Methods The diversification of the clinical symptoms, signs and laboratory indicators of ankylosing spondylitis patients in Yishen Wendu Compound 30 cases of treatment group and sulfasalazine (SASP) 30 cases of control group before and after treatment were observed. Results After treatment, the percentage of ASAS20 standard cases number (%) and the efficacy of TCM syndrome total effective rates of treatment group were 95.83% and 93.3% respectively, superior to sulfasalazine control group 82.5% and 66.7% (P

OBJECTIVE: To investigate the mechanism of Chinese herbal recipe Weichang'an (WCA) in inducing cell apoptosis of human gastric cancer grafted onto nude mice. METHODS: The high performance liquid chromatography was used for monitoring the stability of WCA. A human gastric cancer cell line SGC-7901 grafted in nude mouse was used as the animal model. The mice were divided into untreated group and two experimental groups. Animals in the two experimental groups received either WCA over a 34-day period or 5-fluorouracil (5-FU) over a 6-day period starting at the 8th day after grafting. Animals in the untreated group received normal saline on an identical schedule. Animals were killed 41 days after being grafted. To assess the effect of the treatment on tumor, the tumor weight was determined by the electron balance immediately after the animals were killed. SP immunohistochemical method was used to detect the expression of proliferating cell nuclear antigen (PCNA) in grafts. Apoptotic indices (AI) of the tumor cells were examined by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate fluorescence nick end labeling (TUNEL) method. SP method was also used to detect the expressions of cleaved caspase-3, caspase-8 and caspase-9. SYBR green dye I real-time quantitative polymerase chain reaction (real-time quantitative [corrected] PCR) was used to assess the related gene alterations in mRNA level. The expressions of phospho-Stat3 (Tyr705) and bcl-2 proteins were detected by using SP method. RESULTS: Compared with the untreated group, tumor growth was significantly inhibited by treatment of WCA or 5-FU (P<0.01, respectively). The tumor inhibition rate in the WCA-treated group was 48.70% and that in the 5-FU-treated group was 60.10%. The average labeling index (LI) for PCNA in the WCA-treated group and 5-FU-treated group was significantly decreased as compared with that in the untreated group, respectively. The AI of human gastric cancer grafted in the nude mice detected by using TUNEL method was significantly increased to (9.72+/-4.51)% in the WCA-treated group, while it was (2.45+/-1.37)% in the untreated group. 5-FU-treated group was also found a significantly increased AI compared with the untreated group. The expressions of cleaved caspase-3 and caspase-9 in the WCA-treated group and 5-FU-treated group were significantly increased as compared with those in the untreated group. But caspase-8 showed no significant alteration either in the WCA-treated group or in the 5-FU-treated group. The expression levels of Stat3 (2(-)delta delta C(T))=0.16) and bcl-2 (2(-)delta delta C(T))=0.10) detected by using real-time quantitative [corrected] PCR were lower in the WCA-treated group than those in the untreated group. The expressions of phospho-Stat3 (Tyr705) and bcl-2 in the WCA-treated group were significantly decreased as compared with those in the untreated group. CONCLUSIONS: Chinese herbal recipe WCA can inhibit gastric cancer cell SGC-7901 growth in vivo, induce gastric cancer cell apoptosis and suppress the cell proliferation. WCA induces apoptosis through the caspase-9 and caspase-3 pathway in vivo. Its mechanism might be involved in the down-regulation of Stat3 and bcl-2 genes.

OBJECTIVE: To observe the protective effects of Yanggan Lidan Granules (YGLDG) on carbon tetrachloride (CCl(4))-induced liver damage in mice and to find out its mechanism. METHODS: A model of chronic liver damage was established in mice by intraperitoneal injection of CCl(4). After three weeks, those model mice were treated with low-, medium-, high-dose YGLDG, Danning Tablets and bifendate respectively for four weeks. Then the levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), as well as the contents of superoxide dismutase (SOD) and malondialdehyde (MDA) in liver tissues were detected. RESULTS: YGLDG could significantly reduce the levels of serum ALT and AST in model mice, and the content of MDA was obviously decreased while the content of SOD was increased in liver tissue. CONCLUSION: The therapeutic effect of YGLDG on mice with CCl(4)-induced liver damage is to relieve the seriousness of liver damage, and its mechanism may relate to reducing peroxidation activity in liver tissue.

OBJECTIVE: To evaluate the growth-inhibiting and anti-metastasis effects of Weichang'an Decoction (WCAD) on orthotopic transplant nude mouse model of human gastric cancer. METHODS: Forty-one nude mice were implanted with SGC-7901 cells at orthotopic site, whereas 25 were implanted with SGC-7901 cells subcutaneously. Then the nude mice in each transplantation model were divided into the same three groups which were WCAD-treated group with WCAD 0.5 ml/d taken orally, 5-FU-treated group with 5-FU 50 mg/kg intraperitoneally injected weekly and untreated control group with physiological saline 0.5 ml/d taken orally. The growth-inhibiting rates of transplant tumors were detected and the metastatic lesions were examined in the orthotopic transplant mouse model while PCNA-positive rate and apoptotic index (AI) were observed in the subcutaneous transplant mouse model. RESULTS: The growth-inhibiting rates in the WCAD-treated and 5-FU-treated groups of orthotopic transplant mouse model were 40.82% and 37.92% respectively whereas those of subcutaneous transplant mouse model were 48.70% and 60.10%. The incidence rates of metastasis in perigastric lymph notes, lymph nodes in the porta hepatis, liver, diaphragm and peritoneum in the WCAD-treated and 5-FU-treated groups were lower than those in the untreated control group, and the total metastasis rates in the WCAD-treated, 5-FU-treated and the untreated control groups were 30.77%, 28.57% and 71.43% respectively with significant differences (P<0.05). The total PCNA-positive rates in the WCAD-treated and 5-FU-treated groups were obviously lower than that in the untreated control group (P<0.05 or P<0.01) while the AI was higher than that in the untreated control group (P<0.01). The growth-inhibiting rate, total PCNA-positive rate and total metastasis rate in the WCAD-treated group had no significant differences as compared with those in the 5-FU-treated group, but the AI in the WCAD-treated group was significantly higher than that in the 5-FU-treated group (P<0.05). CONCLUSION: WCAD has the inhibiting effects on tumor growth and metastasis of gastric cancer which is orthotopic implanted onto nude mice. This effect may be obtained by proliferation suppression and apoptosis induction in cancer.

OBJECTIVE: To evaluate the efficacy and safety of Danning Tablet (DNT) in patients with non-alcoholic fatty liver disease (NAFLD) of damp-heat syndrome type. METHODS: A multicenter, randomized, double-blinded and positive drug parallel controlled trial was performed. One hundred and thirty-five patients were enrolled into the study and divided into two groups: DNT-treated group (n=102) and ursodeoxycholic acid (UDCA)-treated group (n=33). Body mass index (BMI), principal symptoms, liver function, blood lipids, iconographic, and compositional parameters were measured before and after treatment, respectively. RESULTS: In the two groups, BMI, distress in hepatic region, fatigue, anorexia, liver function, blood lipids and iconographic parameters were significantly improved, and the improvements of BMI, distress in hepatic region were better in DNT-treated group than in UDCA-treated group. The histological study also showed that DNT had positive effect in treatment of NAFLD. CONCLUSION: DNT is an effective drug to treat patients with NAFLD of damp-heat syndrome type and is more effective than UDCA.

Traditional Chinese medicine (TCM) is considered an important complementary therapy with beneficial effects for cancer patients. Elderly patients with non-small-cell lung cancer (NSCLC) are a complex patient group with increasing co-morbidity and shrinking physiological reserve, and may derive substantial benefit from the supportive aspects of TCM. Researchers from Shanghai Longhua Hospital found that qi and yin deficiency is a common syndrome in patients with stage III or IV lung cancer. This project was designed to study the combination of single-agent chemotherapy with TCM methods of benefiting qi and yin in elderly patients with advanced NSCLC.
