The present invention belongs to the field of medicinal chemistry, health food products and medicine. To be specific, the present invention relates to a composition of forsythia suspensa extract (preferably also including panax ginseng extract), the preparation method, and its application in achieving the antiviral, antipyretic, anti-inflammatory and immunity boosting effects, including the application of forsythin, forsythin derivatives and the composition of forsythin and phillygenin in the manufacturing of health products and drugs for the prevention and treatment of diseases associated with human cy tomegalovirus infection.
Human cytomegalovirus (HCMV) is also known as a cellular inclusion body virus because the infected cells become swollen and contain large intranuclear inclusion bodies. HCMV belongs to the beta-herpesvirus subfamily. With a diameter of approximately 200 nm. HCMV is one of the largest animal viruses. It has a core of 64 nm in diameter containing viral DNA. which is enclosed by a icosahydron with a diameter of 110 nm. The entire particle is enclosed by a capsule consisting of at least 25-30 proteins or glycoproteins encoded by the virus particles. The genome of HCMV is approximately 235-240 kb long with a molecular weight of 150-160 × 103 kDa. HCMV is a linear double-stranded DNA virus. It is composed of two components or segments, the unique long (UL) and unique short (US) regions. As the two components have different directions or are inversed at the junctions, the DNA molecules have four different isomers. HCMV is widely distributed so that animals can also be infected, which may cause infections of various systems, mainly the genitourinary system and central nervous system and liver diseases, and the severity ranges from mild asymptomatic infection to severe defects or even life-threatening.
The HCMV gene contains three genetic fragments encoding the infected cell-specific polypeptides, i.e., the immediate early (IE) protein, early (E) protein and late (L) protein. The three proteins have inununogenicity and are time-phase dependent. The transcription and translation of HCMV genes are regulated by themselves and the host cells. The expression of immediate early genes and early genes are regulated by the promoters. The detection of these two genes is mostly seen in acute infections. The transcription and translation of the late genes are regulated by IE genes. E genes and proteins. The detection of late genes indicates that HCMV is in the latent period and the viral assembly is mature, which is the consequence of HCMV infection. There are three morphological transformation regions in HCMV genome, namely the mtrI, mtr II and mtr III, which can induce cell transformation. MtrI is located on the E fragment of Hind III at the left end of the U genome of AD169 strain. It is 588 bp long and can transform the NIH 3T3 and primary mouse embryonic cells. Mtr II is located on the EM fragment of Xbal/Bam HI of the DNA of HCMV Towne strain. It is 980 bp long and can transform the NIH 3T3 and rat-2 cells. It has its corresponding regions on the ADI69 and TdCMV Tanaka of HCMV strains and contains two isolated promoters. P1 and P2. Mtr II is present in all the transformed cells and the resulted tumor cells. Mtr III is located in the Xbal/BamHI fragment and encodes the major immediate early protein with a molecular weight of 72 kD, which is involved in the transactivation and self-regulation of the virus. Mtr III does not exist in the transformed cells.
At the cellular level, HCMV infections are classified into three types: 1) toxigenic infection; 2) latent infection; 3) cell transformation or latent carcinogenesis. In in vitro studies, after HCMVs were inoculated into human fibroblasts, cell strains containing HCMV antigens were formed, which had the characteristics of transformed cells. The specific fragments of HCMV-DNA were extracted and used to transfect cells, and some of the cells could be transformed by integrating the DNA into the chromosomal DNA of the cells, and the transformed cells were inoculated into athymic nude mice to produce tumors. In a study by Liu Chaoqi et al.. the HPV DNA-immortalized human cervical epithelial cells constructed by the transfection using the HCMV IE were inoculated to the nude mice. The results showed that HCMVs were integrated into the chromosomes of the cells of the animals, acted synergistically with HPV16 to promote the malignant transformation of cervical epithelial cells, and formed tumors in the nude mice, indicating the close relationship between HCMV and cervical cancer. In a study conducted by Lu Deyin et al., ultraviolet inactivated HCMVs were inoculated into the uterine cervix of mice three times a week for 8 consecutive weeks. The results showed that the incidence rate of cervical precancerous lesions of the HCMV group was 27.8% (23/83), and that of cervical cancer was 20.5% (17/83).
CMV has the typical morphology of herpesvirus (HSV), and its DNA structure also resembles HSV. but it is 5% larger than the size of HSV. Human cytomegalovirus (HCMV) is highly species-specific to the host or cultured cells. HCMV can only infect humans and proliferate in human fibroblasts. In cell culture, HCMV proliferates slowly and requires a long replication cycle. It generally takes 30 to 40 days to develop the cytopathic effect (CPE) during the initial isolation and culture. The lesions are characterized by the appearance of round and enlarged cells, enlarged nuclei, and a large eosinophilic inclusion body surrounded by a “halo” in the nuclei. The immune function of the cells in the human body plays an important role in the onset and development of CMV infections. Cellular immune deficiency may lead to severe and long-term CMV infection, and further suppress the cellular immune function, such as decreases in the viability of killer T cells and the function of NK cells. After primary CMV infection, the body can produce specific antibodies and killer T lymphocytes, activating the NM cells. The antibody has a limited capacity to prevent the virus replication of CMV, and has a certain resistance to the reinfection by the same virus strain. However, it cannot resist the reactivation of endogenous latent viruses or exogenous infections caused by other different CMV strains. While the species specific killing T lymphocytes and antibody-dependent cytotoxic cells can exert the greatest antiviral effect.
HCMV infection is very common in the population, which can cause a variety of diseases. In adults, immunodeficient or immunosuppressed patients are mostly affected by the HCMV infections. Especially patients receiving immunosuppressive agents after organ or bone marrow transplantation and those with malignant tumors after receiving radiotherapy and chemotherapy are highly susceptible to HCMV infection. The incidence of HCMV infection in AIDS patients is also very high. Due to the high prevalence of HCMV infection and the potential serious consequences, great attention has been paid to HCMV infections all over the world, which is of great significance in exploring the epidemiology, diagnostic techniques, treatment and prevention of HCMV infections as well as the related basic research on the virology. After receiving chemotherapy or radiotherapy, the immune function of tumor patients is much lower than that of normal individuals, and it is easy for the latent human cytomegalovirus (HCMV) to be reactivated and cause serious infections. It is an important factor for infections that affect the survival rate and the quality of life of tumor patients.
CMV infection is a congenital or acquired infection caused by cytomegalovirus (CMV). CMV is a double-stranded DNA virus belonging to the subgroup of the herpes virus family. Its morphology is similar to that of other herpes viruses and has obvious species specificity to the host cells or cultured tissue cells. Human CMVs can only be isolated and cultured in human embryonic fibroblasts.
HCMV infection is widespread in the human population. The infection rate among adults in China is more than 95%, and the infection in adults mostly affects patients with immune deficiency or immunosuppression. Especially patients receiving immunosuppressive agents after organ or bone marrow transplantation and those with malignant tumors after receiving radiotherapy and chemotherapy are highly susceptible to HCMV infection. Most of the infected patients will present with no clinical symptoms, but the virus invasion into multiple organs and systems can cause severe diseases under certain conditions. HCMVs may invade the lung, liver, kidney, salivary gland, mammary gland and other glands, as well as multinucleated white blood cells and lymphocytes, and can be discharged from saliva, milk, blood, urine, semen, and uterine secretions for a long time or intermittently. Multiple routes, such as oral cavity, genital tract, placenta, blood transfusion or organ transplantation, usually transmit the virus.
1. Congenital infection: in pregnant women with HCMV infection, the virus can invade the fetus through the placenta and cause congenital infection, and in rare cases, which may result in premature delivery, abortion, stillbirth or death after birth. The neonates may develop jaundice, hepatosplenomegaly, thrombocytopenic purpura or hemolytic anemia. Most of the surviving neonates will have the sequelea of permanent mental retardation, neuromuscular dyskinesia, deafness and chorioretinitis.
2. Perinatal infection: when HCMV is discharged from the urinary tract and cervix of the puerpera, the infants can be infected through the birth canal during delivery. Most infants will develop subclinical infections with slight or no clinical symptoms, whereas some will have slight respiratory tract obstruction or liver injury.
3. Infections in children and adults: the virus can be transmitted through the routes of breast-sucking, kissing, sexual contact and blood transfusion, and the symptoms caused by the infections are usually subclinical. In some cases, it may lead to heterophil antibody negative infectious mononucleosis. The latent viruses in monocytes and lymphocytes can be activated due to factors including pregnancy, immunosuppressive therapy, organ transplantation and tumors, resulting in mononucleosis, hepatitis, interstitial pneumonia, retinitis, encephalitis, etc.
4. Cell transformation and carcinogenic potential: UV-inactivated HCMVs can transform the embryonic fibroblasts of rodents. In some tumors, such as cervical cancer, colon cancer, prostate cancer and Kaposis sarcoma, the detection rate of HCMV DNA was found high and the titer of HCMV antibody was also higher compared to normal individuals. In addition, the viral particles were also detected in the cell lines constructed from these tumors, suggesting that HCMV, like other herpes viruses, has carcinogenic potential. After receiving chemotherapy or radiotherapy, the immune function of tumor patients is much lower than that of normal individuals, and it is easy for the latent human cytomegalovirus (HCMV) to be reactivated and cause serious infections. It is an important factor for the infection that affects the survival rate and the quality of life of tumor patients.
Most patients with HCMV infection are in the latent infection state. So, even if HCMV is replicated in the body, it will cause asymptomatic infections in most cases. Currently, no anti-HCMV drugs are available that are both effective and safe. Therefore, the treatment for HCMV infection is still limited to symptomatic treatment. Ganciclovir can only be used with caution for symptomatic infections due to its toxic side effects, such as myelosuppression. Ganciclovir DHPG can prevent the spreading of HCMV infection. If it is co-administered with high titer anti-HCMV immunoglobulin, the mortality of complications of HCMV pneumonia can be reduced in patients undergoing bone marrow transplantation. For HCMV-infected patients with resistance to ganciclovir DHPG, foscarnet sodium can be used. This drug can persistently reduce the spreading of HCMV infection, but with poor effect compared with ganciclovir. The anti-HCMV live vaccines developed in other countries can induce generations of antibodies, but whether the carcinogenic potential of the vaccine can be ruled out remains unknown.
Forsythia suspensa is a commonly used traditional Chinese medicine in clinical settings with wide application and huge consumption. It has the functions of clearing heat, detoxifying, subduing swellings, dissolving lumps, and scavenging free radicals. In clinical settings, it is often prepared into formulas with other Chinese herbal medicines and used to treat various viral infection-related diseases. After painstaking explorations, the inventors prepared and extracted the active monomeric compounds forsythin and phillygenin, and synthesized and prepared forsythiin derivatives through chemical synthesis. Based on a series of pharmacological activity studies carried out by the inventors, it was found that forsythiin, forsythiin derivatives and the composition of forsythiin and phillygenin are effective in treating human cytomegalovirus infection, which provided new approaches for the prevention and treatment for this kind of disease.
Panax ginseng belongs to the genus Panax of the Araliaceae family. It has been widely used in China. Korea and Japan for over 2000 years. It is mainly indicated for the prevention of diseases and prolonging life expectancy. According to the records in the Shennong’s Classic of Materia Medica, panax ginseng has the following therapeutic effects, including nourishing the five viscera, calming the nerves, settling the mind, stopping the palpitation due to fright eliminating the evil, improving the eyesight and intelligence, conducive to controlling body weight and prolonging life expectancy. Modern medical studies have shown that panax ginseng’s main functions and effects include regulating the central nervous system, exerting anti-cancer and anti-tumor effects, regulating immune functions, exerting anti-diabetic effects, enhancing liver function, improving cardiovascular and cerebrovascular disorders, exerting anti-arteriosclerosis effects, regulating blood pressure, improving climacteric disorders, exerting anti-osteoporosis effects, and exerting anti-fatigue, anti-oxidation as well as anti-aging effects, etc.

Biosafety cabinet: BHC-1300 II A/B3, AIRTECH; CO2 Incubator: MCO-18AIC, SANYO; Inverted microscope: CKX41, OLYMPUS; Electronic analytical balance: AR1140/C, DHAUS; Medium: DMEM. HyClone; Fetal bovine serum: HyClone; Trypsin: Gibco; MTT: Sigma; DMSO: Tianjin Beilian Fine Chemicals Development Co.. Ltd.
Vero cells were subcultured for 1-2 days until they reached confluency. When a clear boundary appeared and strong stereoscopic and refractive index were observed, they were digested with trypsin. When pinpoint-like holes appeared on the cell surface, the digestive fluid was aspirated completely. Then, the cells were split up by several milliliters of culture medium, counted, then diluted to about 5×107/L with culture medium (DMEM containing 10% fetal bovine serum), and inoculated into a 96-well culture plate to form a monolayer.
Cytotoxicity test: Dilute the drugs at the concentrations shown in Table 1-1 for cytotoxicity determination.
The above drug that was diluted to different concentrations with the cell maintenance medium (DMEM containing 2% fetal bovine serum) was added dropwise to the monolayer of Vero cells, at 0.2 mL per well, in 9 replicate wells for each concentration. Additionally, prepare 9 wells of normal control (blank control group without drug added) and 9 wells of blank control (medium). Then, the cells were cultured in a 5% CO2 incubator at 37° C. Observation for CPE was performed with an inverted microscope and recorded every day. After 72 h, 20 µL of MTT solution (5 mg/mL) was added to each well, and incubation was continued for 4 h; the medium in each well was aspirated and discarded, and 100 µL of DMSO was added into each well. The plate was shaken for 5 min, the OD value was measured at 492 nm, and the cell survival rate was calculated. Probit regression analysis was performed on the cell viability in the SPSS 18.0 statistical software, and the maximum non-toxic concentration (TC0) and half toxic concentration (TC50) of the drug to Vero cells were calculated.
The viruses were diluted on a 10-fold basis to different dilutions of 10-1, 10-2, 10-3, 10-4, 10-5 and 10-6 and inoculated in sequence into the monolayer of Vero cells in the 96-well culture plate, at 100 µL per well, in 10 wells for each dilution. Additionally, a normal cell control group was prepared. The plate was incubated in 5% CO2 at 37° C. for 2 h. and the virus suspension was discarded. Then, 100 µL of cell maintenance medium was added to each well, and the plate was incubated in 5% CO2 at 37° C. Observation for cytopathic effect was performed with a microscope from Day 3. and the results were interpreted and recorded on Days 7-8. The highest dilution that could cause 50% of the cell wells to show positive cytopathic effect was used as the endpoint, and the virus titer was calculated by Spearman-karber method.
Formula:
(TCID50: 50% tissue cell infective dose; XM: logarithm of the dilution of the highest dilution of virus concentration;
d: logarithm of dilution factor (fold); Σpi: sum of percent cytopathy at each dilution.)
The culture plate covered with cell monolayers was taken, and the medium was aspirated and discarded. The cells were inoculated at the virus challenge amount corresponding to 100TCID50, and cell adhesion was allowed in a 5% CO2 incubator at 37° C. for 2 h. Drug solutions of specific concentrations (maximum non-toxic concentration) were added, and incubation was performed in 10 replicate wells for each concentration at 200 µL/well. Ribavirin Injection and Oseltamivir Phosphate were set as positive drug control groups. Meanwhile, a blank control group (without virus and drug added) and virus control group (with virus added but without drug added) were wet up. Observations were made on the effect of drugs on viral CPE. After 72 h, the OD value was measured by MTT colorimetric assay at the wavelength of 492 nm, and the effective antiviral rate (ER%) was calculated. In the SPSS 18.0 statistical software, the significant differences were analyzed on effective antiviral rate among drugs by ANOVA.
ER% = (mean OD value of drug treatment group - mean OD value of virus control group)/(mean OD value of cell control group - mean OD value of virus control group) × 100%
The maximum non-toxic concentration (TC0), half toxic concentration (TC50) of each drug on Vero cells and the concentration used for the antiviral test are shown in Table 1-2.
The effective rates of drugs against viruses and the results of one-way analysis of variance by ANOVA method are shown in Table 1-3 and Table 1-4.
Tables 1-3 and 1-4 show that the panax ginseng-forsythia suspensa composition groups significantly inhibited 8 kinds of viruses (P < 0.01 or P < 0.001). The effective rates of influenza virus, parainfluenza virus, herpes simplex virus type I (HSV-I), enterovirus 71 and adenovirus (ADV) reached 100%, and the curative effect was significantly better than that of forsythin and ginsenoside Rg3. indicating that the panax ginseng-forsythia suspensa composition groups had a synergistic effect. In addition, the inhibitory effects of panax ginseng-forsythia suspensa composition groups on influenza, coxsackievirus A16 (CoxA16), respiratory syncytial virus (RSV), herpes simplex virus type I (HSV-I), adenovirus (ADV), enterovirus 71 (EV71) and coxsackievirus B3 (CVB3) were significantly better than positive drug ribavirin (P < 0.01 or P < 0.001). The inhibitory effects on influenza, coxsackievirus A16 (CoxA16), respiratory syncytial virus (RSV), herpes simplex virus type I (HSV-I), adenovirus (ADV), enterovirus 71 and coxsackievirus B3 (CVB3) were significantly better than oseltamivir phosphate (P < 0.05 or P < 0.01, P < 0.001).
Kunming mice were provided by Laboratory Animal Center, Norman Bethune Health Science Center. Jilin University, YDZ No. 10-5219.
Influenza virus and parainfluenza virus (cell lysate) were serially diluted at 10-fold to the concentrations of 10-1, 10-2, 10-3, 10-4 and 10-5. One hundred and twenty Kunming mice were divided into the influenza virus group (n=60) and parainfluenza virus group (n=60), each of which was divided into 6 groups randomly. The mice were lightly anesthetized with ether and intranasally infected with a virus solution of different dilutions at 0.03 mL/animal. Meanwhile, a blank control was set up, where the virus suspension was replaced with normal saline. Observation for mortality and survival was performed daily until 14 days after infection. The death within 24 h of infection was non-specific death, which was not counted. The LD50 of virus solution was calculated by Karber’s method. Calculation formula:
[where: LD50: median lethal dose; XM: logarithm of the highest dilution of virus concentration: d: logarithm of dilution factor (fold); and Σpi: sum of percent cytopathy at each dilution].
Five hundred and forty-four-week-old Kunming mice were selected for two tests.
Firstly. 270 mice were randomly divided into 27 groups, with 10 mice in each group, and used to determine the lung index and lung index inhibition rate of panax ginseng-forsythia suspensa composition on influenza and parainfluenza virus-infected mice. Ninety mice were selected for each test, and the test was repeated 3 times. Another 270 mice were randomly divided into 27 groups, with 10 mice in each group, which were used to determine the virus hemagglutination titers in lung suspension of panax ginseng-forsythia suspensa composition groups. Ninety mice were selected for each test, and the test was repeated 3 times.
A mass of absorbent cotton was put in a 200-300 mL beaker, then an appropriate amount of ether was poured (to wet the absorbent cotton), the beaker loaded with absorbent cotton was inverted, and a mouse was placed in the beaker for anesthesia. When the mouse appeared to be extremely excited and then obviously weak, the mouse was placed in a supine position and infected intranasally with 15LD50 influenza virus and parainfluenza virus at 0.03 ml/nostril. For the blank control group, the virus suspension was replaced with normal saline.
The panax ginseng-forsythia suspensa composition groups, ginsenoside Rg3 group, forsythin group, ribavirin and oseltamivir phosphate control group were adininistrated by gavage on the day before infection, respectively. Panax ginseng-forsythia suspensa composition groups were divided into high, middle and low dose groups, and the dosage was 13.0. 6.5 and 3.25 mg/kg, respectively. The dosage was 13 mg/kg for the forsythin group, 13 mg/kg for the ginsenoside Rg3 group. 58.5 mg/kg for the ribavirin positive drug group and 19.5 mg/kg for the oseltamivir phosphate group, once daily for 5 days. The blank control and virus control groups were administrated by gavage with the same volume of normal saline.
On the 5th day after drug administration, the mice were fasted for 8 h, weighed and sacrificed by eyeball removal and exsanguination. The thorax was opened, and the whole lungs were removed, washed twice with normal saline, and the surface was dried with filter paper, and the lungs were weighed by electronic balance. The lung index and lung index inhibition rate were calculated according to the following formulas:
The lungs of mice in each group were removed on the 5th day after treatment and ground into homogenate with a homogenizer at a low temperature. The homogenate was diluted into 10% lung tissue suspension with normal saline, which was then centrifuged, and the supernatant was taken and diluted on a fold basis. The diluted supernatant was dropped into a titration plate at 0.2 ml/well, and 0.2 ml of 1% chicken red blood cell suspension was added into each well, and the mixture was mixed well and kept at room temperature for 30 min. The hemagglutination titer was observed and recorded. The endpoint was the agglutination of the red blood cells (++), and the titer was expressed by the dilution factor of the suspension.
Kunming mice in the test group were intranasally infected with 30 µL of influenza virus and parainfluenza virus at different concentrations, respectively. The first 3 groups (virus concentrations of 10-1, 10-2 and 10-3) showed symptoms of varying degrees on day 3 of infection: piloerection, trembling, and reduced food consumption, etc.; On day 5, the mice appeared to wobble while walking. Death was observed in the mice in the highest virus concentration group on day 6, and deaths in the other groups were observed successively on day 7 after infection. At the end of 14-day observation, the number of dead mice in each group was counted, and the results are shown in Tables 1-4 and 1-5 below. The LD50 was calculated as a dilution of 10-2.9 for the influenza virus and a dilution of 10-2.5 for the parainfluenza virus.
The LD50 of virus was calculated by the Karber method. The LogLD50 of influenza virus is as follows:
The LD50 of virus was calculated by the Karber method. LogLD50 of parainfluenza virus is as follows:
The mean lung index of mice infected with influenza virus and parainfluenza virus showed that compared with the infection model group, the lung index of the blank control group, forsythin group (13.0 mg/kg/d), ginsenoside Rg3 group (16.0 mg/kg/d), panax ginseng-forsythia suspensa composition groups (low dose group 3.25 mg/kg/d, middle dose group 6.5 mg/kg/d, high dose group 13.0 mg/kg/d), ribavirin group and oseltamivir phosphate group decreased significantly (P < 0.05 or P < 0.01). The panax ginseng-forsythia suspensa composition groups had a significant protective effect within the concentration range of 3.25-13.0 mg/kg/d, with significantly reduced lung index and significantly better inhibitory rate on lung tissue lesion index than that of the forsythin group and ginsenoside Rg3 group (P < 0.01 or P < 0.05). See Tables 1-6 and 1-7 for the results.

The hemagglutination titers (InX) of the virus in lung tissues in the infection model group were 32.40 and 33.11, respectively, after infection with influenza virus and parainfluenza virus in mice. The hemagglutination titers of virus in lung tissues were decreased in the panax ginseng-forsythia suspensa composition groups at different concentrations after 5 days of treatment, and the difference was significant when compared with the infection model group (P < 0.01). The hemagglutination titers of influenza virus and parainfluenza virus with different doses of panax ginseng-forsythia suspensa composition groups were significantly lower than those in the forsythin group and ginsenoside Rg3 group (P < 0.05 to P < 0.001), indicating that the composition had a synergistic effect. The inhibitory rates of the panax ginseng-forsythia suspensa composition groups against virus proliferation were significantly higher than those of the forsythin group and ginsenoside Rg3 group (P < 0.05 to P < 0.001). The inhibitory rates of the high, middle and low dose groups of panax ginseng-forsythia suspensa composition against the hemagglutination titer of the lung suspension of mice infected with influenza virus were significantly higher than those of the Forsythin group and ginsenoside Rg3 group (P < 0.01 to P < 0.001). The results of the above tests are shown in Tables 1-8 and 1-9.

Rank sum test. X2 test and t test were used for statistical analysis.
There are sweat glands on the plantar skin of rats, so the changes in sweat secretion can be observed by the purple reaction between the iodine-starch mixture and the sweat.
Five hundred Wistar rats, half male and half female, weighing 120-150 g, were taken in the study. They were randomly divided into 50 groups according to body weight and sex, namely the control (0.5% carboxymethylcellulose) group, forsythin group, ginsenoside Rg3 group, low, middle and high dose groups of panax ginseng-forsythia suspensa composition (2.5, 5 and 10 mg/kg. respectively) and positive drug pilocarpine (35 mg/kg) group, with 10 rats in each group, and 10 groups for each test, for totally 5 time periods of testing (1, 5, 10, 15 and 20 min). The rats were placed in a homemade rat-fixing bag to expose both hind limbs. The dirt on the right paw was gently scrubbed with a cotton swab dipped in absolute ethanol. Except for the pilocarpine solution, which was given by subcutaneous injection, other groups were administered by gavage. One hour after administration (30 min after administration in the pilocarpine group), the sweat secreted from the right paw of rats in each group was gently cleaned with a dry cotton swab before the study and during struggling. The right paw was coated with Wotan-Takagaki’s reagent A solution (dissolve 2 g of iodine in 100 mL of absolute ethanol) and then coated with Wotan-Takagaki’s reagent B solution (mix 50 g of soluble starch and 100 mL of Ricinus conununis oil well) after reagent A was fully absorbed. The color and number of dark purple spots (i.e. sweat spots) were observed carefully with a magnifying glass at 1, 5, 10, 15 and 20 min, respectively, after applying solution B. At the end of the test, a rank-sum test was used to analyze the differences among the groups.
Compared with the control group, the middle and high dose groups (5 and 10 mg/kg) of panax ginseng-forsythia suspensa composition could significantly promote the sweat secretion of rat paw at 10, 15 and 20 min after applying solution B (p < 0.05), and the 2.5 mg/kg group of panax ginseng-forsythia suspensa composition could significantly promote the sweat secretion of rat paw at 15 and 20 min after application of solution B (p < 0.05). The sweating effect was comparable with the positive drug pilocarpine, and the panax ginseng-forsythia suspensa composition could slowly promote the rat paw’s sweat secretion. The high dose group of the panax ginseng-forsythia suspensa composition was significantly superior to forsythin and ginsenoside Rg3 (p < 0.05) in promoting sweat secretion of rat paw following 10, 15 and 20 min after applying solution B. The middle dose group of the panax ginseng-forsythia suspensa composition was significantly superior to forsythin and ginsenoside Rg3 (p < 0.05) in promoting sweat secretion of rat paw following 10 and 15 after application of solution B. The low dose group of the panax ginseng-forsythia suspensa composition was significantly superior to forsythin and ginsenoside Rg3 (p < 0.05) in promoting sweat secretion of rat paw following 15 min after application of B solution. The above test results show that the effect of panax ginseng-forsythia suspensa composition groups was significantly superior to that of forsythin and ginsenoside Rg3 in promoting sweat secretion of rat paw. Please see 2-1. 2-2, 2-3. 2-4, and 2-5 for details.
*P < 0.05 for the comparison between each test group and the virus control group; #P < 0.05 for the comparison between panax ginseng-forsythia suspensa composition and forsythin; ▲P < 0.05 for the comparison between panax ginseng-forsythia suspensa composition and ginsenoside Rg3.
After sweat glands activation in rats, besides the increase of sweat secretion, the morphology of the epithelial cells of the sweat glands changes accordingly. Under the optical microscope, the increase and enlargement of vacuoles in the epithelial cells of the sweat glands are observed. Under an electron microscope, the enlarged vacuoles appear to be due to swelling and rupture of mitochondria, enlargement of fusion and secretory vesicles in the epithelial cells of sweat glands. The secretory activity of sweat glands could be understood by observing the histomorphology of the epithelial cells of plantar sweat glands of rats.
Three hundred Wistar rats, half male and half female, weighing 120-160 g. were taken in the study. They were randomly divided into 30 groups according to body weight and sex, namely the control group (0.5% carboxymethylcellulose), ginsenoside Rg3, forsythin, low, middle and high dose groups of panax ginseng-forsythia suspensa composition (2.5, 5, 10 mg/kg) and positive drug pilocarpine group (35 mg/kg), with 10 rats in each group, and 3 tests for each group. Except for the pilocarpine solution given by subcutaneous injection, other groups were administered by gavage. One hour after the control group was given 0.5% carboxymethyl cellulose, 30 min after the positive drug group was given pilocarpine, and 1 h after the administration of forsythin, ginsenoside Rg3 and the panax ginseng-forsythia suspensa composition, the right hind limb was immediately cut off at the level of the ankle joint. Then, the right plantar pad was removed, placed in 10% formaldehyde solution, fixed, dehydrated, embedded, sectioned and stained with HE. Observations were made under an optical microscope for changes in the epithelial cells of the plantar sweat glands of rats in each group, mainly the incidence of vacuoles. The statistical processing was performed by X2 test, and differences among the groups were compared. The above study was repeated for 3 times.
Compared with the control group, the 2.5 mg/kg. 5 mg/kg, 10 mg/kg groups of panax ginseng-forsythia suspensa composition very significantly promoted the sweat secretion of rat paw (p < 0.001). The low, middle and high dose groups (2.5, 5 and 10 mg/kg) had significantly better efficacy than forsythin and ginsenoside Rg3 (p < 0.001 or p < 0.01), indicating that the compositions of panax ginseng and forsythia suspensa have a synergistic effect. The test results are shown in Tables 2-6;

Male Wistar rats: weighing 180-200 g. Before the test, the normal rectal temperature was measured twice with WSC411P portable digital thermometer (at a certain interval), and the mean value of the two measurements was taken as the normal body temperature of the rats. Then. 300 rats with a body temperature of 36.5 ~ 38° C. were randomly divided into 30 groups: the model group (0.5% carboxymethylcellulose), low, middle and high dose groups of panax ginseng-forsythia suspensa composition (2.5, 5, 10 mg/kg), forsythin group (13 mg/kg), ginsenoside Rg3 group (13 mg/kg) and positive drug paracetamol group (100 mg/kg), with 10 rats in each group, and 3 replicate tests for each group. The rats in each group were subcutaneously injected with 10% fresh beer yeast suspension at 10 mL/kg on the back to induce fever. Six point zero hours after administration of 10% fresh beer yeast suspension, the composition of ginsenoside Rg3 and forsythin and paracetamol were given by gavage, and the model group was given an equal volume of 0.5% carboxymethylcellulose by gavage. Rectal temperature was measured at 1, 2, 3 and 4 h after administration. Observations were made on changes in body temperature, and the differences among the groups were compared by t-test of antipyretic percentage. The above study was repeated 3 times.
Six hours after subcutaneous injection of 10% fresh beer yeast suspension to rats in each group, the body temperature increased by about 1.5° C., which was significantly different from that before fever induction (p < 0.001), indicating that the rat fever model induced by beer yeast was established successfully. Compared with the model group, a significant temperature-lowering effect on the rat fever induced by beer yeast suspension was noted in the middle and high dose groups of panax ginseng-forsythia suspensa composition at 1, 2, 3 and 4 h after drug administration and in the low dose group of panax ginseng-forsythia suspensa composition at 2, 3 and 4 h after drug administration (p<0.05 to p<0.001). Meanwhile, the different doses of panax ginseng-forsythia suspensa composition were significantly superior to the forsythin group and ginsenoside Rg3 group (p < 0.001 or p < 0.01) in lowering the temperature, indicating that they had a significant synergistic effect. The results of the above study are shown in Tables 2-7.
Two hundred and twenty male Wistar rats weighing 120-150 g were randomly divided into 22 groups, namely the control group (0.5% sodium carboxymethylcellulose), low, middle and high dose groups of panax ginseng-forsythia suspensa composition (2.5. 5, 10 mg/kg), forsythin group, 20(R)-ginsenoside Rg3 group and positive drug aspirin group (200 mg/kg), with 10 rats in each group. Each group was administered by sublingual intravenous injection. Before the study, the normal volume of the right hind limb was measured by the capillary magnification method. To avoid errors, the measurement position should be fixed and performed by one person before and after administration. The average of the two measurements was taken as the normal volume of the right hind limb of the rats prior to administration. Immediately after administration, 0.1 ml of 1% carrageenan was subcutaneously injected into the right hind paw of rats to induce inflammation. The right hind plantar volume was measured at 15, 30, 60, 120, 180, 240, 300 and 360 min after inflammation induction. The inter-group t-test was performed by the difference percentage (swelling rate) of the plantar volume before and after the inflammation induction, and the differences among the groups were compared.
Compared with the blank control group, the rat paw swelling induced by carrageenan was significantly inhibited (p < 0.05 or p < 0.01) in the high dose group (10 mg/kg) of panax ginseng-forsythia suspensa composition within 15 min to 360 min after administration, the middle dose group (5 mg/kg) and the low dose group (2.5 mg/kg) within 30 min to 360 min after administration, and the efficacy was significantly better than that of the forsythin 10 mg/kg group and 20(R)-ginsenoside Rg3 10 mg/kg group (p < 0.05 or p < 0.01). The efficacy of the above-mentioned dose groups of the composition was very significantly better than that of the 20(R)-ginsenoside Rg3 group at 60 min and 240 min after administration (p < 0.01). The above study results showed a significant synergistic effect when forsythin in the panax ginseng-forsythia suspensa composition was combined with 20(R)-ginsenoside Rg3. See Table 2-8 for details.

Kunming mice, aged 6-8 weeks, weighing 18-22 g. were purchased from Experimental Animal Center of Dalian Medical University, with quality certificate No.: SCXK (13) 2013-0003.
One hundred and fifty-two healthy male mice were subjected to acclimation for 4 days before they were randomly divided into 19 groups: the negative control group, positive control group, forsythin group, 20(R)-ginsenoside Rg3 group, high, middle and low dose groups of panax ginseng-forsythia suspensa composition. The positive control groups were given pidotimod (50 mg/kg), forsythin (144 mg/kg), and 20(R)-ginsenoside Rg3 (144 mg/kg); the panax ginseng-forsythia suspensa composition groups were given low dose (36 mg/kg), middle dose (72 mg/kg) and high dose (144 mg/kg). The drugs were given by gavage, once daily for 30 days, and the negative control group was given the same volume of water.
At 1 h after the last dose, the spleens of animals of each group were aseptically excised to prepare splenocyte suspension. After diluting the splenocyte suspension to a concentration of 3×106 cells/mL, the splenocyte suspension was divided into 2 aliquots.Each of the aliquot was transferred into two 24-well culture plates at a volume of 1 mL/well followed by addition of 75 µL of ConA solution (a) was added to one well, and the other well was used as control (b). The wells were cultured at 37° C. for 72 h. Then, thiazolyl blue (MTT) was added 4 h before the end of the culture. After incubation, acidic isopropanol was added, and the absorbance (ABS) of each solution was measured at 570 nm after it was mixed well. The proliferativity was calculated using the formula: proliferativity = ABSa-ABSb. Each dose group of the test sample was compared with the negative control group. The experimental results are shown in Table 1.
One hour after the last dose, the spleens of animals of each group were aseptically excised to prepare splenocyte suspension. After the red blood cells were lysed with sterile water for injection, the cell suspension was diluted with 1% glacial acetic acid. Then, the concentration of splenocyte suspension was adjusted to 2×107 cells/mL. and the splenocyte suspension was added into a 96-well plate for culturing. For each animal, the wells were divided into reaction wells (splenocyte suspension and YAC-1 cell suspension 100 µL each, effector-to-target ratio 50:1), natural release wells (YAC-1 cell suspension and culture medium 100 µL each) and maximum release wells (YAC-1 cell suspension and 1% NP40 100 µL each). A triplicate set of tubes was prepared for each of the above items. The 96-well plate was incubated at 37° C. in a 5% CO2 incubator for 4 h. After adding LDH matrix solution and 1 moL/L HCl, the solutions in each parallel well were combined, and the absorbance (ABS) was measured at 490 nm. The NK cell viability was calculated: NK cell viability (%) = (ABS reactionwell -ABS naturalreleasewell)/(ABS maximumreleasewell -ABS naturalreleasewell). The experimental results are shown in Table 1.
Following the stimulation of T lymphocytes by ConA, the blast cells will have proliferative responses. The mitochondrial hydrolase in the viable cells, especially the proliferating cells, decomposes MTT into blue-purple crystals. Increased optical density value, if any, indicates that the cell proliferation ability is enhanced. As shown in Table 1, the optical density differences of the high, middle and low dose groups of the panax ginseng-forsythia suspensa composition were higher than those of the negative control group, indicating that this sample had the effect of promoting the proliferation of splenocytes.
After the cells are killed by the NK cells, the LDH in the cytoplasm of viable cells will be released out of the cells, dehydrogenate lithium lactate and reduce NAD to NADH, and NADH is further reduced to iodonitro-tetrazolium chloride (INT) through hydrogen transmitter phenazine methosulfate (PMS). After receiving H+, the INT is reduced to a purple formazan compound, and the optical density value is determined using a microplate reader. As shown in Table 1, the NK cell viability of the high, middle and low dose groups of the panax ginseng-forsythia suspensa composition was significantly higher than that of the negative control group, indicating that the sample could increase the viability of the NK cells.
The above study results showed that different doses of the panax ginseng-forsythia suspensa composition could promote the proliferation of spleen cells and enhance the activity of NK cells. Moreover, the composition of panax ginseng and forsythia suspensa had a synergistic effect, and could significantly promote the proliferation of spleen cells, enhance the activity of NK cells and improve immune function.
