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.

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.

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.

OBJECTIVE: Cerebral vasospasm (CVS) induced by subarachnoid hemorrhage (SAH) is a difficulty in neurosciences. Because the pathogenesis of CVS remains a matter of discussion, clinical prevention and treatment are currently not sufficient. With the application of advanced experimental technology in recent years, great breakthroughs have been achieved in domestic and foreign studies on potassium channels. Definite mechanism in the region plays a significant role in instruction for clinical prevention and treatment. In this paper, researches related to potassium channels in cerebral vascular vessels after SAH are reviewed.DATA SOURCES: Related articles published between January 1991 and December 2005 were searched by the computer in Medline database with the key words of "potassium channels, subarachnoid hemorrhage, cerebral vasospasm" and the language was limited to English. Meanwhile, relevant articles were also searched in CNKI and Wanfang database with the same key words in Ghinese.STUDY SELECTION: All articles were selected firstly, and literatures related to potassium channel on physiology and pathogenesis of SAH-induced CVS were selected. Researches on biochemistry and gene etc were excluded.DATA EXTRACTION: A total of 45 English articles were collected, among which, 17 met the inclusion criteria. Of 2 Chinese articles collected,one study was in accordance with the inclusion criteria. Eighteen literatures on the pathological and physiological mechanism of CVS after SAH were looked for the full text.DATA SYNTHESIS: Researches showed that remarkable changes occurred in potassium channels in CVS after SAH, while potassium channel modulators had significant interventional effect on CVS in animal experiment by promoting or blocking the ion movements.CONCLUSION: Potassium channels plays an important role in the pathogenesis of SAH-indueed CVS. Some therapeutic intervention may be provided based on the studies of potassium channels in CVS.
