Objective Jizhipingchuan soft capsula is mainly used to treat acute bronchitis and acute attack of chronic bron-chitis.This paper investigate the antitussive, antiasthmatic and expectorant effects of Jizhipingchuan soft capsula according to its func-tions. Methods The antitussive effect of Jizhipingchuan soft capsula was observed in cough mouse model induced by ammonia and in guinea cough pig model induced by citric acid, and the latent period of asthma was observed in guinea pig induced by acetylcholine chloride and histamine phosphate.Its expectorant effect was evaluated by the excretion of phenol red in mice and the exudation phlegm in rats. Results Jizhipingchuan soft capsula could decrease the frequence of cough induced by ammonia in mice and induced by cit-ric acid in guinea pig.It could prolong the latent period of cough in guine pig and also prolong the latent period of asthma in guine pig induced by acetylcholine chloride and histamine phosphate.Jizhipingchuan soft capsula could significantly increase the amount of phe-nol red secreted in mice and the phlegm exudation of rats. Conclusion Jizhipingchuan soft capsula showed definite antitussive, an-tiasthmatic and expectorant effects.

Objective To investigate the relationship between the serum concentrations of brain derived neurotrophicfactor (BDNF) and its G196A polymorphism in the amphetamine induced-psychosis inpatients.Methods The cross-sectional study included 233 amphetamine abuses and 110 healthy participants who served as controls.The serum concentration of BDNF was measured by sandwich ELISA,and the genotype of BDNF G196A polymorphism was determined used polymerase chain reaction (PCR) techniques.The data were analyzed using SPSS 12.0 statistics software.Results The serum concentration of BDNF in case group((205.81±75.36) pg/ml) were significantly higher than that in control group((95.04±31.63) pg/ml;t=15.02,P＜0.01).There was no significant difference about the BDNF serum concentrations between the inpatients with the amphetamine induced psychosis and the inpatients with the amphetamine abuse (P＞0.05).The BDNF serum concentration showed no significant difference in the genotype distributions and allele frequencies (P＞0.05).The genotype distributions and allele frequencies of BDNF G196A showed no significant difference among three groups(P＞0.05).Conclusion The BDNF serum concentration is correlated with methamphetamine abuse,while the BDNF G196A gene polymorphism may not be associated.

OBJECTIVE: To reveal the characteristics of gene expression in adrenal gland of H22 tumor mice with typical syndromes and in different liver cancer stages. METHODS: By the quantitative four diagnosis and syndrome differentiation methods and GeneChip Mouse Exon 1.0 ST Array, we observed adrenal gland gene expression in H22 tumor mice with pathogenic factor-toxin predominance syndrome and qi deficiency syndrome in the earlier stage, yang-qi deficiency syndrome in the intermediate stage, and qi-yin-yang deficiency syndrome in the advanced stage. Genes highly expressed and remarkably different were analyzed in this study. RESULTS: A total of seventy-three up-regulated coincident genes and twenty-six down-regulated coincident genes in different stages were investigated in the study. Up-regulated coincident genes included Hp, C3, Anxa1, Procr, C2, Il4ra, Cd14, Ptprc, Cd52, C4b, Eno3, Xdh, Gpx3, and so on. Down-regulated coincident genes included nervous system function-related genes such as Plp1, Mbp, Aldh1a1, Cck, Atn1, genes associated with electrolyte metabolism such as Aldh1a1 and Slc22a17, genes related to signal transduction such as Cxcr4, Spag5 and Stmn3, etc, and genes related to transcriptional control and protein biosynthesis such as Hspa1a, Dnajb1, Thra, Hhex and so on. CONCLUSION: With the development of the tumorigenesis, the symptoms and signs and differentially expressed genes in adrenal gland of H22 tumor mice can be measured. Up-regulated and down-regulated coincident genes may be the features of H22 tumor mice different from those of normal mice.
