Aim To investigate the effect of procyanidins on apoptosis in brain of experimental rats with intracerebral hemorrhage(ICH) and its possible mechanisms.Method Rat intracerebral hemorrhage model was established by injecting collagenase into the brain caudate nucleus.Fifty-four health Sprague-Dawley rats were divided into six groups randomly: sham operation group,model group of intracerebral hemorrhage,treatment groups with procyanidins at doses of 50 mg?kg~-1,100 mg?kg~-1 and 200 mg?kg~-1,and positive control group with nimodipine at dose of 10 mg?kg~-1.Twentyfour hours after operation,the content of glutathione(GSH) and activity of catalase(CAT) were measured.The levels of bax and bcl-2 were detected by method of immunohistochemistry,and the apoptosis in brain tissues was detected by method of TUNEL.Result In procyanidins groups(50,100 and 200 mg?kg~-1),the content of GSH and the activity of CAT were significantly higher than those in ICH group(P

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. The prevalence of NAFLD is increasing year by year in the world, which seriously threaten the public health. The pathogenesis of NAFLD is complex, and there is no specific treatment for NAFLD. Natural-derived compounds have the characteristics of multi-target and multi-mechanism, which can improve the curative effect and reduce the toxic and side effects by regulating multiple factors of the disease. They are ideal drugs for treating complex diseases and have unique advantages in improving NAFLD. However, low intestinal absorption, poor bioavailability, and single medicine efficiency limit the utilization of many compounds, and further drug development and clinical application are challenging. This paper reviews the research progress of natural-derived compounds in the prevention and treatment of NAFLD in recent years, analyzes the existing problems, and discusses the improvement strategies, so as to provide reference for related research.

BACKGROUND: After local injection of Botulinum toxin type-A (BoTX-A), not only the function of the neuromuscular conjunction was affected, but also the changes occurred remote from the injected site. F-waves result from the back fire of the motoneuron activation, which may indirectly reflect the functional state of the motoneurons.OBJECTIVE: To evaluate the remote effect of local BoTX-A injection by F-wave test.DESIGN: Self-control study based on patients with movement disorders.SETTING: Neruologic clinic in a university hospital.PARTICIPANTS: Twenty-six patients with movement disorders not received previous local BoTX-A were selected from Neurological Clinic in Renmin Hospital of Wuhan University between September 2002 and July 2003, including 19 cases with hemificiospasm, 5 Meige syndrome and 2 torticollis spasmodicus.INTERVENTIONS: F- and M-waves of ulnar and tibial nerves were recorded before 1, 12 - 24 weeks after local injection of BoTX-A in 26 patients.MAIN OUTCOME MEASURES: The following parameters were analyzed:latency(ML) and amplitude (Mamp) of M-wave, minimal (Fmin) and average latency (Fave), amplitude of negative peak(Famp), duration (Fdur), persistence (Fpcr) and chronodispersion (Fchr) of F-wave.RESULTS: No definite F-response of ulnar nerve stimulation was obtained 1 week after injection in 3 HFS patients (5 nerves) . Fave prolonged significantly on ulnar and tibal nerve and Fdur increased significantly on ulnar nerve 1 week after injection, but there was no significant difference 12 - 24 weeks later, compared with before injection. No significant correlation of the altered F-wave parameters was found with the dosage of BoTX-A.CONCLUSION: Fdur and Fave could sensitively assess the remote effect,which correlates with distance away from the injected muscle, rather than the dosage of BoTX-A.

ObjectiveTo investigate the treatment effects of comprehensive nursing intervention on patients with chronic obstructive pulmonary disease(COPD) treated by non-invasive mechanical ventilation with BiPAP mode.Methods96 patients with diagnosed COPD and using non-invasive mechanical ven- tilation with BiPAP mode were randomly divided into the control group(46 cases) which was treated with routine measures and the comprehensive nursing intervention group (50 cases) which adopted comprehen- sive nursing intervention according to experimental design. The frightening degree, incidence rate of com- plications and clinical treatment effect by ventilator were compared between the two groups.ResultsPa- tients compliance with treatment and clinical treatment effect by ventilator in the comprehensive nursing in- tervention group was better than that of the control group. The frightening degree and incidence rate ofcomplications were lower than those of the control group (P < 0.01 ).ConclusionsComprehensive nurs-ing intervention with non-invasive mechanical ventilation with BiPAP mode can improve the treatmentcompliance of COPD patients,reduce complications followed by non-invasive mechanical ventilation andreach the prospective treatment effect.

This study was aimed to collect relevant provisions of bulging disease medical records in the Ming and Qing dynasties to excavate the syndrome differentiation, drug law and medication frequency analysis. A database was established to analyze relevant provisions. The results showed that the syndromes of liver stagnation and spleen deficiency, dampness-heat accumulation, spleen-yang deficiency are the most common type. The mainly used drugs are from the category to eliminate dampness and water, and to tonify the deficiency. The top three used drugs are poria, atractylodes, and dried citrus peel. It was concluded that medications used in the Ming and Qing dynasties were mainly targeted to the disordered zangfu-organ, which was mainly about the spleen and the stomach. The syn-drome differentiation is the mixture of deficiency and excess. And deficiency is the main part. The medication should combine tonification and reducing. And tonification should be paid attention to. The syndrome differentiation and treatment should be coordinated and the primary and secondary aspect should be identified. These rules provide ref-erence effect for the clinical practice and scientific research of bulging disease treatment.

Objective:To investigate the mechanism responsible for lost sensibility of tyrosine aminotransferase(TAT)to dexam- ethasone(Dex)in human hepatoma cell line SMMC-7721 through examining the cDNA sequence of TAT and the status of glucocorticoid receptor(GR)pathway.Methods:The TAT cDNA fragment containing the full length of coding sequence was amplified by reverse transcription-polymerase chain reaction(RT-PCR)and was sequenced.The expression of TAT mRNA was determined by real-time quantitative PCR to observe the influence of Dex on expression of TAT mRNA in SMMC-7721 cells.The experiement with HepG2 cells was performed as the control.Reporter genes(GRE-tk-LUC and GRE-MMTV-CAT)were transiently transfected into SMMC-7721 cells by electroporation.The induction efficiencies of LUC and CAT genes expression by Dex were examined and compared between SMMC-7721 cells and HepG2 cells.Results:The results showed that there was a same-sense mutation(Gln576Gln)in TAT cDNA se- quence.TAT mRNA could be induced by Dex,with the maximal induction level being 2.22-folds in SMMC-7721 cells,which was signifi- cantly lower than that in HepG2 cells(15.1-fold increase,P
