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 .

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 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.

Objective To investigate the distribution characteristics and antimicrobial resistance of carbapenem-resistantAcinetobacter baumannii (CRAB),and to guide effective clinical prevention and rational antimicrobial use. Methods Data about clinically isolated CRAB between January 2009 and December 2013 were analyzed retrospec-tively,distribution and antimicrobial resistance were analyzed by WHONET 5.5 software.Results A total of 888 Acinetobacter baumannii strains were isolated,421 of which were CRAB,the isolation rate was 47.4%,the isola-tion rates in 2011 ,2012 and 2013 were all about 50.0%;CRAB strains were mainly isolated from sputum (73.4%) and mostly distributed in intensive care unit (ICU)(61 .3%),followed by neurosurgery department (12.4% ). CRAB presented highly antimicrobial resistance.Except cefotaxime and cefatriaxone,resistant rates of CRAB to the other detected antimicrobial agents(ceftazidime,cefepime,cefoperazone/sulbactam,aztreonam,imipenem,amika-cin,gentamycin,minocycline,chloramphenicol,levofloxacin,ciprofloxacin,and compound sulfamethoxazole)were all higher than non-CRAB isolates(all P ≤0.01),Compared with non-CRAB isolates,The resistant rate of CRAB to cefoperazone/sulbactam was the lowest(<15%),followed by minocycline,resistant rates to other antimicrobial agents were all >80.0%.Conclusion Surveillance of CRAB should be further strengthened.It is necessary to fo-cus on the control and prevention of healthcare-associated infection in ICU patients and respiratory system.

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.
