Objective To explore the effective molecular mechanism of PPAR-γligands rosiglitazone to biliary ischemia-reperfusion injury in autologous liver transplantation. Method A total of 40 SD rats were randomly (random number) divided into sham operation group (SO), ischemia - reperfusion group (Ⅰ/R), rosiglitazone (ROS) and GW9662 group, with 10 ones in each. The models, rat biliary ischemiareperfusion injury of autologous liver transplantation, were made by modified two-cuff technique. Tissues of the liver and bile ducts and blood of those models were evaluated by pathological and biochemical methods to make sure the models were made successfully or not. SO group suffered autologous orthotopic liver transplantation, and L/R group suffered both that and ischemia-reperfusion. ROS group were injected rosiglitazone (0.3mg/kg) via portal vein after having been done all as I/R. GW9662 group suffered all as ROS, and 10min later ,they were injected GW9662(0.3mg/kg) via portal vein. 4h after the experiment, tissues of livers and bilary ducts were taken to be tested by immunohistochemistry method, and the blood punctured from the right ventricular were taken to be determined by ELISA. ANOVA was used for statistical analysis.Results IL-1β, TNF-α and IL-6 were mainly expressed in the cytoplasm of hepatocytes and bile duct cells,while NF-κB was expressed both in the cytoplasm and nuclei. Expression of those proteins in L/R and GW9662 group was increased, significantly higher when compared to the SO and ROS (P ＜ 0.05). IL-1β,TNF-α and IL-6 in rat serum were simultaneously increased, and significantly higher than SO(P ＜0.05).Compared with the SO, expressions of the IL-1 β,TNF-α and IL-6 were not significantly changed in ROS (P＞ 0.05 )but significantly increased in GW9662. Conclusions PPAR-γ ligand rosiglitazone took protective role in biliary ischemia-reperfusion injury in autologous liver transplantation. The mechanism correlates with the release of the IL-lα, IL-1β and TNF-α and other inflammatory mediators, which decreased as the expression of NF-κB inhibited by its antagonist.

Objective To observe the clinical efficacy of electroacupuncture plus moxibustion in treating infantile cerebral palsy. Method Eighty eligible patients with infantile cerebral palsy were randomized into a treatment group of 42 cases and a control group of 38 cases. The control group was intervened by physiotherapy (PT), while the treatment group was given electroacupuncture at scalp acupoints, body acupuncture, and moxibustion along the Governor Vessel in addition to the treatment given to the control group. The two groups were treated once a day, 6 months in total. The comprehensive ability and the Gross Motor Function Measure (GMFM) were evaluated before and after the interventions in the two groups, and the clinical efficacies were compared.Result After 6-month treatment, the total effective rate was 92.9% in the treatment group versus 78.9% in the control group, and the total effective rate of the treatment group was superior to that of the control group (P<0.05). The motor function and activities of daily living were significantly improved in both groups after the interventions (P<0.05,P<0.01); after the treatment, there were significant differences in comparing the motor function and activities of daily living between the two groups (P<0.05). The GMFM scores of each domain were significantly changed after the treatment in both groups (P<0.05); after the treatment, there were significant differences in comparing the GMFM scores of each domain between the two groups (P<0.05).Conclusion Compared with being used alone, conventional PT can more significantly benefit the improvement of motor function of cerebral palsy patients when electroacupuncture and moxibustion were added.

“Multi-component Chinese medicine” was derived from effective clinical prescriptions, which is similar to natural medicines, and its form is similar to the fixed-dose compounds. The adaptable indications mainly cast chronic, intractable, and complex diseases. Its research targets of pharmacology mostly are diseases, symptoms or pathological process. Vivo and vitro experiments can be used in its researches. Its dose-effect relationship mostly shows non-linear relationship, and three elements (dose, efficacy and syndrome) are involved. However, the comprehensive evaluation method is still in the exploratory stag. In the safety evaluation, there were few general pharmacological researches, and the basis of toxicity and the relationship between amount and toxicity need further study. In combined optimization aspect, including identification of components and component ratio optimization, many methods have been developed, but it still needs to be developed in theory and systemic integration. Pharmacological mechanism researches focus on the multi-component, multi-target, multi-pathway, and multi-pharmacodynamics aspects, combined with new ideas and new technologies, such as systems biology, network pharmacology, etc. But as multi-component medicine, it should also be studied about the correspondence and network relationships of component and target, with a purpose to explain the contribution of each component in overall mechanism.
