RESUMO
OBJECTIVE: We wished to study the impact of Chaihushugan San (CSS) on the behavior of perimenopausal rats with liver-Qi stagnation (LQS) and to investigate the effect of CSS on signal transduction of the Raf/mitogen-activated protein kinase (MEK)/ extracellular signal-regulated kinase (ERK) cascade in the hippocampi of rats induced by immobilization. METHODS: Twenty 52-week-old female rats were divided into two groups by the random number table method: model control group (MCG) and CSS group (CSSG), with 10 rats in each group. Ten-week-old female rats were used as the normal control group (NCG). CSS effects were assessed using rats exposed to immobilization stress by measuring body weight and sucrose consumption, serum hormone levels, and observing performance in the open field test (OFT). Molecular mechanisms were examined by measuring the effect of CSS on expression of Raf1, MEK1/2 and ERK1/2 mRNA in hippocampi using quantitative real-time polymerase chain reaction and by measuring levels of these proteins and related phospho-proteins using Western blotting. RESULTS: Perimenopausal rats with LQS had decreased locomotor activity; reduced sucrose consumption; and increased serum levels of corticotropin releasing hormone (CRH) and corticosterone (CORT). Activation of hippocampal Raf/MEK/ERK cascade was suppressed significantly in the MCG, and activation was increased after 21 days of CSS treatment. CONCLUSION: CSS has significant effects upon relief of the symptoms of LQS in immobilization-induced rats. The mechanism underlying this action might (at least in part) be mediated by reversal of disruption of the Raf/MEK/ERK pathway.

Objective: To explore the tongue epithelial cell apoptosis quantitatively to analysis tongue demonstration change mechanism of perimenopausal syndrome by Chaihu Shugan Decoction. Methods: Patients with perimenopausal syndrome 60 cases, divided into kidney yin deficiency (30 cases), deficiency of both kidney yin and yang (30 cases), 30 healthy cases in normal group. The treatment course lasted for 2 months. The flow cytometry was used to detect the tongue epithelial cell apoptosis. Results: The tongue epithelial cell apoptosis rate of perimenopausal syndrome patients was higher than that in the normal group (P

Objective To study the clinical effect of the treatment for knee osteoarthritis by dissolving the phlegm-stasis.Methods The 100 cases of knee osteoarthritis were randomized into the treatment group and control group with 50 in each.The former was treated by oral administration of Chinese herbal medicine while the latter by oral administration of Votalin and vitamin C.One week as one course,two courses in succession.The comparative analysis on symptom score and therapeutic effect of two groups before and after treatment was carried out.Results After treatment,the symptom scores of both groups were significantly lowered(P
