OBJECTIVE: To assess the efficacy and safety of Sanjin tablets in the treatment of urinary tract infection. METHODS: Retrieved from electronic databases and references literatures by on-line or manual way, RCTs about Sanjin tablets in the treatment of urinary tract infection were collected. Related data were obtained and analyzed with evidence-based medical software statistically. RESULTS: 1 046 patients in 13 studies with were included. Two studies showed that Sanjin tablets had better effect than amoxicillin, ciprofloxacin, erythromycin and norfloxacin in the treatment of urinary tract infections. One study showed there was no significant difference in efficacy of Sanjin tablets and Modified juling tang. Other trials showed that there was no difference in efficacy between Sanjin tablets and Chinese herbal medicine, antibiotics. Three trials showed Sanjin tablets combined with Chinese herbal medicine or antibiotics had the same effect with antibiotics alone in the treatment of urinary tract infection. No severe ADR induced by Sanjin tablets was found in included studies. Funnel plot which assumed asymmetry indicated the existence of publication bias and unsatisfactory methodological quality. CONCLUSION: Few trials show efficacy of Sanjin tablets are better than antibiotics. Most of studies show that there is no significant difference between Sanjin tablets and antibiotics. At present no evidence indicate that efficacy of Sanjin tablet is superior to other drugs. The methodological quality of clinical trials of Sanjin tablets for urinary tract infections should be improved.

The influence of anisodamine on the cerebral blood flow in the uncompletely ischemic brains was studied with radioactive biomicrosphere assay. After the bilateral carotid arteries were occluded the cerebral blood flow drawmatically decreased and middle part of the hemisphere had the most severe reduction. Anisodamine 10mg ? kg-1 iv selectively increased the cerebral blood flow in this area and 20mg ? kg-1 increased that in the whole hemisphere. When it was used in the dose of 40mg ? kg-, the increasing effect on the cerebral blood flow became weaker. While the cerebral blood flow decreased, the myocardial blood flow increased significantly after bilateral carotid artery occlusion. Anisodamine 20mg ? kg-1 iv made it further increase and 40mg ? kg-1 iv made it decrease. The cardiac index was not influenced by bilateral carotid artery occlusion and anisodamine 10~20mg ? kg-1 iv, but was significanntly increased by anisodamine 40mg ? kg-1 iv. These results suggested that anisodamine may be used in the treatment of ischemic cerebral diseases and should be used in different doses according to different purposes.

Objective To study the protective effect of recombination human erythropoietin (rhEPO) on the apoptosis of retinal neurons induced by glutamate.Methods The primary retinal neurons of postnatal SD rats were cultured in vitro for 7 days and divided into 3 groups :control group ,glutamate group and rhEPO pretreatment group.The neurons in the rhEPO pre-treatment group were afterwards allocated to three subgroups in terms of different rhEPO treatments (0.15 ,0.30 or 0.50 U/mL rhEPO for 12 h).Those in glutamate group and rhEPO pretreatment group were treated with glutamate at the concentration of 20μmol/L for 30 min for establishment of the apoptosis model.Twenty-four h later ,the apoptosis index (AI) was assayed by TUNEL and the expressions of BCL-xL mRNA and protein was detected by RT-PCR and immunocytochemistry respective-ly.Results The AI was significantly higher in the glutamate group than in the control group (P<0.01).The AI was signifi-cantly reduced ,and the expression level of BCL-xL mRNA and protein was markedly dose-dependently increased in the rhEPO pretreatment groups compared with the glutamate group (P<0.01).Conclusion The rhEPO pretreatment can inhibit the glu-tamate-induced apoptosis of retinal neurons by up-regulating the expression of BCL-xL .

BACKGROUND: Focal adhesion kinase (FAK) phosphorylation influences the proliferation, migration and apoptosis of cells. However, there are no reports about the role of FAK phosphorylation in migration and proliferation of vascular smooth muscle cells during the process of vascular restenosis.OBJECTIVE : To analyze the correlation between FAK phosphorylation and vascular remodeling after balloon endothelial denudation in rats.DESIGN: Random controlled experiments in animals.SETTING: Cardiology Institute of Xianning College; Shenzhen Center for Chronic Disease Prevention and Control;Department of Cardiology at the Affiliated Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology.MATERrALS: The experiment was carried out in the Laboratory of Cardiology at the Affiliated Tongji Hospital from March to May in 2005. Forty male Wistar rats were used in the study, and they were managed according to the ethical standard of animals.METHODS: ①Forty rats were randomized into five groups (n =8): non-balloon endothelial denudation control group, and 4-day, 8-day, 16-day and 24-day model groups after balloon endothelial denudation. ②The rat models of restenosis following balloon endothelial denudation were built. At days 4, 8, 16 and 24 postoperatively, the denudated vessels were harvested for the detection of the morphological changes, which were taken as the judgment of successful models;Western blot method was used to detect the expression and activity of FAK. Abdominal aorta of left common carotid in rats was served as controls.MAIN OUTCOME MEASURES: The expressions of FAK and phosphorylation FAK in rat artery.RESULTS: Totally 40 rats were all involved in the result analysis.①A small quantity of FAK without phosphorylation could be detected in the controlled rats. Compared with the control group, the expression and activity of FAK in the model group rapidly increased at 4 days after balloon injury (P ＜ 0.05), and they changed in a similar manner with the increase of injury duration. The expression of FAK reached a peak at 8 days and began to descend at 16 days. The expression of phosphorylation FAK reached a peak at 16 days and then rapidly descended. ②Focal hyperplasia of intima was found at 8 days after balloon endothelial denudation, and diffuse hyperplasia of intima was found at 16-24 days after denudation.CONCLUSION: FAK can take part in vascular remodeling after balloon endothelial denudation in rats. The level of intimal hyperplasia is closely associated with the level of FAK and FAK phosphorylation.

The nonstructural protein 5A (NS5A) of the hepatitis C virus (HCV) has been shown to interact with a variety of cellular proteins and implicated in the regulation of cell growth, interferon resistance, and other cellular signaling pathways. Using the yeast-two hybrid method, we have isolated a clone that encodes a novel NS5A--associated binding protein: NS5ABP37. Reverse transcription polymerase chain reaction (RT-PCR) method was employed to amplify the full fragment,and the plasmid pGADT7-NS5ABP37 with the Saccharomyces cerevisiae vector pGADT7 was constructed. To prove the interaction, yeast cell Y187 transformed with pGADT7-NS5ABP37 was mated with yeast cell AH109 containing pGBKT7-NS5A to verify the interaction between the novel protein coded by the new gene NS5ABP37 and NS5A.

Objective HCV NS3 protein plays an important role in disease caused by HCV. We investigate the gene expression of HCV NS3 in yeast for future study of the function of the protein. Methods PCR was performed to amplify the gene of HCV NS3 from the plasmid pBRTM/HCV containing the whole fragment of HCV and the gene was cloned into pGEM T vector. Thereafter, HCV NS3 gene was cut from pGEM T vector and cloned into yeast expression plasmid pGBKT7, and recombinant pGBKT7∶NS3 was transformed into yeast AH109. The yeast protein was isolated and analyzed with sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE) and Western blotting. Results HCV NS3 gene was successfully cloned into pGBKT7. The results of SDS PAGE and Western blotting assay showed that the molecular weight of the expressed product was about 22000 Da and HCV NS3 protein was existed within yeast cells.Conclusions HCV NS3 was successfully expressed in yeast expression system.

Objective To analyze the potential risk factors of sudden death at home in senile people. Methods 38 cases of cardiac arrest in a community occurring at home from 1993 to 2004 were retrospectively analyzed. The data concerning their condition of health before death, the diagnosis of the diseases confirmed, the predisposing causes of cardiac arrest, and the season and time of death were collected and analyzed. Results It was found that hypertension, CHD and diabetes were the predominant diseases in senile patients died of out-of-hospital cardiac arrest. Most of the deaths occurred in April, 73.7% of the deaths occurred during 6:00-18:00, and 81.6% cases occurred in their homes. Conclusion In senile patients, the cardiovascular diseases may be the main risk factors of out-of-hospital cardiac arrest. The patients with myocardial infarction, arrhythmia and heart failure constitute the high risk group of cardiac arrest. Usually death occurs without a portent.
