AIM To observe the effects of Wuwei Wentong Chubi Capsules (Cinnamomi Ramulus,Poria,Epimedii Folium,etc.) on autophagy proteins of Beclin-1 and LC3-Ⅱ in adjuvant-induced arthritis rats and to explore the possible mechanism of action.METHODS Sixty SD rats were randomized into six groups:normal group,model group,Wuwei Wentong Chubi Capsules (0.8,1.6,3.2 g/kg) groups and tripterygium glycosides (TPT,40 mg/kg) group.In addition to the normal group,adjuvant arthritis (AA) was induced with Freund's complete adjuvant.From the 2th day after injection of FCA,Wuwei Wentong Chubi Capsules with different doses and TPT were given by gavage once a day for 12 days.At the end of the experiment,ankle-joint samples were taken to examine the degree of AA by HE.Beclin-1 and LC3-Ⅱ mRNA were determined by real-time fluorescent quantitative PCR.Meanwhile,the protein expression levels of Beclin-1 and LC3-Ⅱ were determined by immunofluorescence histochemical staining and Western blot.RESULTS As compared with the model group,Wuwei Wentong Chubi Capsules (1.60,3.20 g/kg) not only significantly reduced histopathological injuries,but also effectively up-regulated mRNA and protein expressions of Beclin-1 and LC3-Ⅱ.CONCLUSION Wuwei Wentong Chubi Capsules has a therapeutic action on AA in rats,which might be partly associated with promoting autophagy,decreasing excessive proliferation of synovial cells,leading to the reduction of damage to articular cartilage.

Objective To investigate the immunological reaction mechanism of medicated serum in Zibai Gelatin for SiHa cells of the cervical cancer infected by high risk human papilloma virus (HPV). Methods Through immunohistochemical comparison and the cell culture, and after medicated serum was administrated to SiHa cells of cervical cancer for 24 h, 48 h, and 72 h, optical densities of IL-6, IL-10, CD83 and TNF-αin the same time but different concentrations and different times but the same concentration were observed. Relationships of dose-effect and time-effect between expressions of IL-6, IL-10, CD83 and TNF-α and medicine action were analyzed by calculating average optical density. Results With the increase of medicine concentration and administration time of Zibai Gelatin, the expressions of IL-6 and TNF-αgradually decreased, while the expressions of CD83 and IL-10 gradually increased (P<0.05). Conclusion Zibai Gelatin with medicated serum can inhibit local inflammatory reaction by improving local immunologic function of cervix, which is beneficial to reduce cervix high-risk HPV.

Objective:To explore the effect of repetitive high-frequency magnetic stimulation (H-F rTMS) of the dorsolateral part of the prefrontal cortex (DLPFC) combined with smoking-related cues on nicotine addicts′ cigarette craving, the concentration of exhaled CO and sleep quality.Methods:Sixty nicotine addicts were randomly divided into groups A, B and C, each of 20. All were given H-F rTMS five times a week for two weeks, while those in groups A and B watched smoking and non-smoking pictures for ten minutes, respectively. Before and after the intervention, all of the subjects self-reported their cigarette cravings using a visual analogue scale. Exhaled CO (CO ppm) was measured and the Pittsburgh sleep quality index (PSQI) was evaluated. Results:After the intervention the average craving score, CO ppm and PSQI score had improved significantly in all three groups. The average craving score and CO ppm of group A were both significantly better than in the other two groups. Conclusions:rTMS can significantly improve cigarette craving, CO ppm and sleep quality of cigarette adicts. Viewing smoking-related pictures as an addition to rTMS can even better the effects of rTMS.

To elucidate the anti-depressive effect of Fufang Chaigui prescription and its mechanism and investigate its effect on neuroendocrine hormone, rats were included into a chronic unpredictable mild stress (CUMS) model for 28 d, and drugs were administered at the same time. During the period, rats' behaviors were observed and the blood was collected by using ELISA to determine representative hormone concentrations of HPAA, HPTA and HPGA. The changes in endogenous metabolites were analyzed by using H NMR metabolomics to seek the potential biomarkers. Results showed Fufang Chaigui prescription could improve the behaviors of CUMS rats obviously, increase contents of ACTH, CORT, T₃and decrease contents of TSH and TESTO and regulate the levels of lactate, α-glucose, choline, N-acetylglycoprotein, trimethylamine oxide and leucine to get closer to the contents of control group. The results of correlation analysis indicated that HPTA was associated with glycometabolism, amino acid metabolism and choline metabolism. And HPAA was related to glycometabolism and amino acid metabolism. However, HPGA was only correlated with glycometabolism. In conclusion, Fufang Chaigui prescription could show an obvious anti-depressive effect and its underlying mechanism might involve regulations of neuroendocrine function and pathways of glycometabolism, amino acid metabolism and choline metabolism.
