[Method] The model of hyperglycemia mice were obtained by injecting streptozotocin intraperitoneally to study the effect of F. suspensa leaves on lowering blood sugar of hyperglycemia mice and normal ani- mals. [Result] F. suspensa leaves could antagonize the streptozotocin-reducing mice hyperglycemia and significantly reduce the fasting blood glucose level of diabetic mice. [Coaclusion] F. suspensa leaves exhibits a good therapeutic effect on diabetic mice and has a good development prospect.展开更多

Methods: LCR detection of the urine for Neisseriagonorrhoeae and bacteria culture of discharge was per-formed simultaneously to 276 patients with urethritisor cervicitis seeking treatment in sex transmitted dis-eases (STDs) outpatient clinic. For specimens withdiscordant results, polymerase chain reaction wasconducted. The purpose was to detect the respectivesensitivity and specificity of bacteria culture and LCR. Results: 24 of 276(8.7%) patients had positive LCRresults and 21 of 276(7.6%) were positive for culture.5 specimens had discordant results from LCR andbacteria culture. The sensitivity and specificity of LCRin the diagnosis of gonorrhoeae were 92.3% and100% respectively. Conclusion: This study showed that LCR had ahigher sensitivity and specificity for the diagnosis ofgonorrhoeae from urine.展开更多

Methods： Type 2 diabetes mellitus rats were induced by an injection of 35 mg/kg streptozotocin （STZ） and a high-carbohydrate/high-fat diet for 16 weeks. Diabetic rats were given low-, middle-, high-dose berberine （75, 150, 300 mg/kg）, fenofibrate （100 mg/kg） and rosiglitazone （4 mg/kg） for another 16 weeks, respectively. The myocardium structure was observed with hematoxylin ＆ eosin （H＆E） staining and Cdk9 and cyclin T1 protein expressions were detected by immunohistochemistry. Results： Middle-dose, high-dose berberine improved myocardial hypertrophy and interstitial fibrosis of diabetic rats. Cdk9 and cyclin T1 protein were significantly lower in diabetic myocardium than in control one （P〈0.01）, and middle-dose, high-dose berberine and fenofibrate obviously increased both Cdk9 and cyclin T1 expression to near control level （P〈0.01）. Conclusion： Berberine modulates Cdk9 and cyclin T1 protein expression in diabetic myocardium which may contribute to ameliorate myocardium damage.展开更多

Methods: The function of gap junctional intercellular communication in the cultured bladder detrusor cells was detected by fluorescence redistribution after photobleaching. Results: At the fourth minute after bleaching, the mean fluorescences recovery rates of DI group bladder detrusor cells were (35 791±0 836)%, that of control group (8 645±0 673)%. The mean fluorescence recovery rates of DI group were significantly higher than those of control group ( P <0 01). Conclusion: It shows that the increase of intercellular excitatory communication is one of the important reasons of pathogenesis of DI.展开更多
