Objective To study the expression of cytokeratin(CK)20 in exfoliated urothelial cells and to evaluate its clinical significance. Methods The expression of CK20 in exfoliated urothelial cells in 40 patients with bladder cancer and 20 subjects with normal urothelium was observed with immunohistochemical methods. Results The positive staining of CK20 in patients with bladder cancer was 52.5%, the expression of CK20 was negative in all controls, the positive rate of expression of CK20 combining with HE staining in patients with bladder cancer was 90%. The expression of CK20 was significantly higher in recurrent cases(80%) than in primary cases(43.3%). CK20 was not related to the tumor grade or stage. Conclusions The results suggested that the method had a higher specificity and therefore CK20 would be a good diagnostic marker.

Objective To study the characteristics of complement expression and the effects of atorvastatin on the complement in rats after the cerebral ischemic infarction.Method One hundred and sixty adult healthy Sprague-Daweley rats were randomly divided into normal group,sham-operated group,ischemia group and treat group.The ischemia group and treatment group were sub-devided into 6 h,12 h,24 h,48 h,3 d,5 d,2week,respectively.The middle cerebral artery occlusion(MACO)model was induced by using filament method,and the thread Was withdraw from the middle cerebral artery after occlusion 2 h.Rats in the sham-operated groupdid not have thread inserted.After wakefulness,the animals The successful of animal model produced was evidenced by the paralysis of contralateral limbs.The animals model in the treatment group treated with Atorvastatins 10 mg once a day for 2 weeks and,rats in the ischemia group did not receive Atorvastatin.The neurological deficit scoring was measured at different intervals in the ischemia and treat ment groups.The expressions of complement C1q and C3 d protein in the brain of the rats in 4 groups were measured by immunohistochemical methods.Result There were a few complement expression in the brain of normal rats,showing no significant difference observed between sham-operated group and normal group(P＜0.05).The complements(C1 q and C3 d)expressied increasubgkt after cerebral ischemia injury,peaked 24 h after ischemia,and returned to normal levels 5 d after ischemia.The expression of complement C1 q and C3 d in the ischemia group were significanfly higher than those in sham-operated group(P＜0.05),The expression of complement C1 q and C3 d in treat ment group were signnificantly lower than those in the ischemia group(P＜0.05).The neurological deficit score in treatment group were signnificantly lower than that of ischemia group.Conclusions The expressions of complement C1 q and C3 d were increase gradually after cerebral ischemia in the rats,Atorvastatin Can inhibit the complement activation,improve neuro logical function of rats.

DNA methylation is a normal modification mode of eukaryon, there is an intimate relationship between aberrant promoter methylation of tumor-related genes and the generation or development of neo- plasms,emerging significantly biological effectiveness. Aberrant promoter methylation of tumor-related genes as the epigenetic markers, maybe play a very important role in the incidence, diagnosis, therapeutic effects, prognosis judgements and other aspects in gallbladder carcinoma.

Objective To evaluate urinary vascular endothelial growth factor (VEGF) in the diagnosis of bladder cancer. Methods VEGF in urine was measured by enzyme linked immunosorbent assay in 33 cases of transitional cell bladder carcinoma,10 benign urological conditions and in 10 normal individuals. Results The mean urinary VEGF level in 33 patients with bladder cancer was ( 309.8 ? 86.6 )ng/g Cr, significantly higher than in the 20 controls which was (107.6?35.4)ng/g Cr ( P

OBJECTIVE:To explore the new mode of industry-university-institute unification for pharmacy professionals. METHODS:The research-teaching interactive platform was established through the principles of“complementary advantages, shared interests and mutual benefits”. RESULTS:It changed the traditional teaching mode,and it ensured the professional plan-ning,curriculum development and training objectives of students based on“4 analysis,2 setting and 1 implementation”. CONCLU-SIONS:The opportunities for cooperation between students and employers were broadened and students’awareness of innovation and entrepreneurship was enhanced. It cultivates project-based pharmaceutical,technical and skilled personnel,solves the problem of industry-university-institute unification and has certain significance for the development of China’s pharmaceutical education.

Objective To study the effects of erythropoietin(EPO) and angiotensin receptor blocker on the expression of eNOS and Bcl-2 after cerebral ischemia.Methods The model of focal cerebral ischemia was made by occluding middle cerebral artery(MCA) for 2h and reperfusing for 48h in healthy Sprague-Dawley rats.The rats received EPO 3 000u · kg-1 · d-1 or valsartan 40mg · kg-1 · d-1 by intraperitoneal injection just before the beginning of reperfusion and after reperfusion.The expression of eNOS and Bcl-2 was detected.Results Compared with ischemia group,Bcl-2 and eNOS expressions in EPO-treated group and EPO-ARB treated group were significantly increased (P ＜ 0.05).eNOS expression in ARB-treated group was significantly increased (P ＜ 0.05),Bcl-2 expression was up-regulated,but it had no significant difference.Conclusion EPO had protective effects on cerebral ischemia-reperfu-sion injury in rats,which partially mediated by up-regulating of Bcl-2 and eNOS expression.Angiotensin receptor blocker had protective effects on cerebral ischemia-reperfusion injury in rats,which partially mediated by up-regulating of eNOS expression.

Objective To discuss the clinical application value of omeprazole and rabeprazole quadruple therapy on Helicobacter pylori associated peptic ulcer.Methods 360 patients with Helicobacter pylori associated peptic ulcer were selected.They were divided into two groups randomly.The rabeprazole group (180 cases) was treated with rabeprazole with quadruple therapy based,omeprazole group (180 cases) was treated with omeprazole quadruple therapy of short acting as the foundation,to observe and record the two groups of patients with clinical curative effect,the healing rate of ulcer,Helicobacter pylori eradication rate,histopathology and treatment of gastric mucosa during adverse reaction condition.Results The cure rate of rabeprazole group was significantly higher than that of omeprazole group (P ＜ 0.05).Compared the two groups before treatment,upper abdominal pain,abdominal discomfort,belching symptoms,no significant difference,the two groups after treatment in patients with upper abdominal pain,abdominal discomfort and belching percentage of patients decreased,and Rebela was the proportion of patients with lower group (P ＜ 0.05).After treatment,the rabeprazole group of ulcer healing rate 90.5％ (163/180),Helicobacter pylori eradication rate was 87.8％ (158/180),omeprazole group of ulcer healing rate was 70.5％ (127/180),Helicobacter pylori eradication rate was 72.2％ (130/180).The rabeprazole group of the healing rate of ulcer and Helicobacter pylori eradication rate were higher (P ＜ 0.05).Before treatment,there was no significant difference on gastric mucosal histopathological score between two groups.After treatment,two groups of gastric mucosa pathological score were decreased (P ＜ 0.05),no difference between the two groups.During the treatment,there was no significant difference on adverse reactions between two groups.Conclusion Rabeprazole with short acting quadruple therapy can significantly treat Helicobacter pylori causes,promote gastric mucosa repair,improve the clinical symptoms of peptic ulcer,the medication is safe,it is worthy of clinical use.

Objective To investigate the effects of pyrrolidine dithiocarbamate(PDTC) on aquaporin-9(AQP9) expression and brain edema around the hematoma in experimental intracerebral hemorrhage(ICH).Methods 128 SD rats were randomly divided into four groups: normal group,control group,ICH group and PDTC group.According to Rosenberg's methods,the models of experimental ICH were established.The rats in PDTC group were received PDTC intraperitoneally 2 h later.The brain weight column(BWC) at different time point was calculated by gray-wet method,and the expression of AQP9 was examined by immunohistochemistry.Results The BWC and expression of AQP9 in hematoma side of ICH begin to increase 4 h after ICH,peaked at 72 h,and decreased 120 h later.The BWC in opposite side of hematoma also increased 4 h after ICH and peaked at 72 h.Compared with control group,the BWC and expression of AQP9 in ICH group were higher,especially in hematoma side of brain(all(P
