AIM　To study the electrochemical behavior of ofloxacin at Pt/GC ion implantation modified electrode. METHODS　With Pt/GC ion implantation modified electrode as working electrode, the behavior of ofloxacin was studied by voltammetry in 0.40 mol*L-1 KCl solution. RESULTS　A sensitive reductive peak of ofloxacin was obtained by linear sweep voltammetry. The peak potential was -1.35 V (vs SCE). The peak current was proportional to the concentration of ofloxacin over the range of 1.0×10-6-3.0×10-5 mol*L-1 with the detection limit of 5.0×10-7 mol*L-1. The behavior of reduction wave was studied and applied to determination of ofloxacin in tablets. CONCLUSION　The reduction process was irreversible. The element composition, atomicity form and depth of distribution at the surface of Pt/GC electrode were determined by Auger electron spectroscopy (AES), X-ray photoelectron spectroscopy (XPS) and scannig electron microscope (SEM). The catalysis behavior and reaction mechanism at Pt/GC modified electrode was also studied.

Objective Cerebral ischemic tolerance induced by cerebral ischemic preconditioning has become a hotspot in the researches of ischemic cerebrovascular disease, and its specific mechanism remains to be clarified.This study was to explore the brain protection mechanisms of cerebral ischemic preconditioning by observing the expressions of HIF-1αand VEGF in the cortex area sur-rounding the infarct locus in rats with focal cerebral ischemia /reperfusion ( I/R) after cerebral ischemic preconditioning. Methods A total of 130 male SD rats were randomly divided into three groups:sham operation, middle cerebral artery occlusion, and cerebral is-chemic preconditioning, the animals in the latter two groups subjected to 2, 6, 12, 24, 48 and 72 h of I/R.The expressions of HIF-1α and VEGF at different time points were detected by immunohistochemistry and Western blot. Results In the middle cerebral artery occlusion group, the expressions of HIF-1αand VEGF positive cells and proteins increased at 2 h after I/R, reached the peak at 24 h, and then gradually decreased to and at 72 h, but still higher than in the sham operation group (P<0.05).The expressions of HIF-1αand VEGF positive cells were significantly higher in the cerebral ischemic preconditioning than in the middle cerebral artery occlusion group (all P<0.05), so were the expressions of HIF-1αand VEGF positive proteins in the former group than in the latter (all P<0.05).The sham operation group showed only a little in-crease in the expressions of HIF-1αand VEGF positive cells and proteins. Conclusion Cerebral ischemia reperfusion injury induces the expressions of HIF-1αand VEGF, which can be further upregulated by brain ischemic preconditioning.

Objective To establish Helicobacter pylori (Hp) infection induced chronic obstructive pulmonary disease (COPD) rat model,and to explore the role of Hp in the pathogenesis of COPD.Methods40 Wistar rats were randomly divided into double modeling group (Hp infection,smoked and intratracheal instillation of lipopolysaccharide),COPD group (smoked and intratracheal instillation of lipopolysaccharide),Hp infected group and control group.The lung function,cytokines level in serum and bronchial alveolar lavage fluid (BALF),Hp related genes expression in bronchial and lung tissue were detected.And Hp in bronchial and lung tissue was isolated and cultured.Results The lung tissue of both COPD group and double modeling group accorded with COPD pathological characteristics,and the latter was more apparent.The lung function of COPD group and double modeling group decreased more significantly than that of control group and Hp infected group (all P＜0.05),and which was more obvious in double modeling group than that of COPD group (P＜0.05).Along with the Hp colonization density increased,Ri and Re value of double modeling group increased (r=0.785 and 0.905),the value of Gdyn,PEF and FEV0.3/FVC decreased (r=-0.975,-0.959and -0.976).Compared with control group,IL-6,IL-8 and TNF-a cytokines levels in serum and bronchoalveolar lavage fluid of other groups increased significantly (all P＜0.05),and within the groups,double modeling group increased most significantly (all P＜0.05).Hp UreC gene was only amplified in part of bronchi and lung tissue of double modeling group,no Hp and suspicious bacteria colonies were isolated and cultured.ConclusionsHp not directly colonized in bronchi and lung tissue,which aggravated inflammation through increasing the serum and bronchoalveolar cytokines level of COPD rat model.Which caused the deterioration in lung function of COPD group.
