China Pharmacist 2014;(12):2078-2079
Objective:To explore the curative effect and security of Jiuwei Zhenxin granules in the treatment of generalized anxiety disorder. Methods:Totally 112 patients with generalized anxiety disorder were randomly divided into the research group and the control group with 56 ones in each. The research group was given Jiuwei Zhenxin granules while the control group was given paroxetine with the treatment course of 6 weeks. The curative effect of the two groups was observed using Hamilton anxiety scale ( HAMA) , and the side effects were observed using treatment energent eymptom scale( TESS) . Results:After the 2-week treatment, HAMA scores were signifi-cantly lower than those before the treatment (P<0. 01). HAMA scores between the two groups before the treatment and at each time point after the treatment had no statistically significant differences (P>0. 05). The recovery rate and effective rate of the two groups also showed no statistically significant differences (P >0.05). The incidence of adverse drug reactions in the research group was 14. 8%, which was lower than that in the control group (22. 6%, P<0. 05). There was no statistically significant difference in TESS total score between the two groups (P>0. 05). Conclusion:Jiuwei Zhenxin granules show similar effect with paroxetine in the treat-ment of generalized anxiety disorder with lower adverse reaction incidence and promising safety.
3. Effects of halofuginone on hepatic fibrosis in rats and their mechanism
Chinese Traditional and Herbal Drugs 2013;44(23):3352-3358
Objective: To investagate the protective effects of halofuginone against liver injury induced by concanavalin A (Con A) in rats and their mechanism. Methods: Rats were divided into control (G1, 8), model (G2, 14), low- (5 mg/kg, G3, 14) and high-dose (10 mg/kg, G4, 14) halofuginone groups. The rats in G1 were iv injected with 300 μL PBS from tail vain once a week, the rats in other three groups were iv injected with 12.5 mg/kg Con A (in 300 μL PBS) once a week for eight consecutive weeks. Halofuginone was given in the diet for rats in G3 and G4 after molding and continuous administration for eight weeks after the rats were weighted and then were put to execution. The biochemical analysis was used to determine alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein (TP), and album protain (ALB) in serum while enzyme-linked immuno sorbent assay (ELISA) was applied for detecting transforming growth factor β1 (TGF-β1), hyaluronic acid (HA), and procollagen III (PC-III) levels in serum. HE and Masson's trichrome stainings were conducted in liver tissue to observe the pathological variations. Grades of hepatic fibrosis were evaluated according to SSS system. Sirus and immunohistochemical stainings were executed for detecting the deposition and protein expression of collagen 1 (Col I) in liver tissue. Results: Compared with the G2, halofuginone could decrease the levels of ALT, AST, TP, ALB, TGF-β1, HA, and PC-III in serum obviously (P < 0.05, 0.01). Halofuginone could improve the liver pathological variations of fibrotic rats obviously (P < 0.05, 0.01) and reduce the score of hepatic fibrosis significantly (P < 0.05, 0.01). Halofuginone treatment could reduce the deposition and expression of Col I protein (P < 0.05, 0.01). Conclusion: Halofuginone could attenuate the Con A-induced immunological liver injury and the fibrosis level in rats. The mechanisms possibly contribute to down-regulating the deposition and expression of Col I protein in liver of rats.
4.Logic Problem Analysis on Determination of Syndrome-attribution in A Variety of Animal Model Establishment Methods
World Science and Technology-Modernization of Traditional Chinese Medicine 2013;(7):1665-1669
Intervening animals by pathogen of traditional Chinese medicine (TCM) to establish animal model is the most common and easiest method to determine syndrome attribute of an animal model. However, the underlying prob-lem of this modeling method is that the concept of wind, cold and dampness in the nature are confused with the syn-drome of wind-cold-dampness summarized by abnormal appearance of clinical patients. The typical animal model establishment are through the methods of wind blowing, low temperature freezing, cold water immersion, environmen-tal humidity increasing. Modern medical modeling methods, such as chemicals, organ resections, are also used in the establishment of animal models. Then, the syndrome-attribution of modeling animal is evaluated by physicochemical indexes of modern medicine which is one of modeling methods that have been used by academia in early times. But animal model established by this method is a kind of disease model which is lack of sufficient theoretical and clini-cal evidences. Therefore, the syndrome-attribution should be reappraised among this kind of animal models.

Chinese Journal of Tissue Engineering Research 2013;(41):7272-7277
BACKGROUND:Studies have shown that Ganoderma lucidum polysaccharides have biological activities of anti-viral, anti-tumor, enhance immunity, anti-oxidative and anti-aging. OBJECTIVE:To observe the biological effect of Ganoderma lucidum polysaccharides on the antioxidant capacity of D-galactose induced aging mice skin tissues, and to observe the effect in postponing skin aging. METHODS:Forty-four 2-month-old Kunming mice were randomly divided into four groups:normal control group, aging model group, vitamin E group, and Ganoderma lucidum polysaccharide group. Rats in the last three groups received subcutaneous injection (nape area) of Ganoderma lucidum polysaccharide to establish rat aging models, and intragastric administration of corresponding drugs or saline was performed. After 42 days, pathological sections of back skin were obtained to assess the morphological changes of skin tissues, measure the epidermal and dermal thickness, and detect the superoxide dismutase levels and the expression of CuZn-superoxide dismutase mRNA. RESULTS AND CONCLUSION:The epidermal and dermal thickness in the vitamin E group and Ganoderma lucidum polysaccharide group were increased when compared with the aging model group. The superoxide dismutase levels in the Ganoderma lucidum polysaccharide group were significantly higher than those in the other two groups. The decreased degree of cycle threshold value in the Ganoderma lucidum polysaccharide group was lower than that in the other two groups. The results indicate that Ganoderma lucidum polysaccharide can increase the epidermal and dermal thickness, improve the skin tissue structure, and enhance the superoxide dismutase levels and the expression of CuZn-superoxide dismutase mRNA.
