Objective To investigate the changes of uveoscleral pathway by an I1 receptor agonist,moxonidine,and with pretreatment of antagonists topical administration,and to study the mechanism that moxonidine improves uveoscleral outflow.Methods Moxonidine was administered unilaterally and topically to rabbits and with pretreatment of the antagonists,namely,prazosin,yohimbine and efaroxan.FITC-BSA,a tracer agent,was injected into the anterior chamber after moxonidine treatment or with pretreatment of the antagonists.Frozen sections were undertaken at different time points between 2 to 10 h.Fluorescence intensity was observed in the sites of uveoscleral pathway in the sections by fluorescence microscopy.Results Bilateral fluorescence intensity treated with moxonidine was more intense than that with placebo,and the most intense regions of fluorescence were ciliary body and superchoroidal space.Fluorescence intensity by prazosin pretreatment was not significantly different compared to that by moxonidine,while yohimbine and efaroxan pretreatment decreased the intensity compared with moxonidine(P

Objective To explore the clinical significance of monocyte chemoattractant protein-1(MCP-1)in children with Henoch-Schonlein purpura nephritis(HSPN).At the same time compare the association between serum and urine MCP-1,to investigate the impact of the both on them in children with HSPN.Methods Serum and urine MCP-1 were measured by enzyme linked immunosorbent assay in 50 children with Henoch-Schonlein purpura(HSP)(25 cases of them patients with renal injures),and 25 healthy children,the changes of serum and urine MCP-1 were compared;at the same time serum urea nitrogen,creatinine,urinary albumin,urine N-acetyl-D-glucosaminidase(NAG),urine ?2-MG,24 hours urinary levels of protein were investigated in children with HSPN by analyzing the correlation between these indicators and serum and urine MCP-1;urine MCP-1 in HSPN group were measured in recovery period,and were compared with urine MCP-1 in HSP group and HSPN group in acute period.Results 1.The expressions of urine MCP-1 was significantly higher in HSPN group than those in HSP group and healthy controls(P0.05).2.Urine MCP-1 levels were associated with proteinuria in children with HSPN,but serum MCP-1 levels had nothing to do with HSPN.3.There was a close correlation between urine MCP-1 expression and urinary albumin,urine NAG,urine ?2-MG and 24 hours urinary levels of protein,but the expression of urine MCP-1 levels were not correlated with the serum urea nitrogen and creatinine.4.There was statistical significance in urine MCP-1 in acute and recovery periods with HSPN group(P

AlM:To investigate the effect of teaching mode of problem- based learning ( PBL ) in the teaching of medical students' clinical ophthalmology.
METHODS: Five classes ( total 148 students ) were randomly selected as experimental group, using PBL method, at the same time another 5 classes ( total 151 students) were also randomly selected as control group, using lecture-based learning ( LBL) mode in 2010 grade. The scores of the experimental group were compared with control at the end of term. ln addition, students and teachers were respectively interviewed using self -administered questionnaire to obtain their evaluation for PBL practice.
RESULTS:The mean scores of PBL group (78. 35±7. 63) were significantly higher than control group (71. 68±6. 37) (P<0. 001). Most of students thought that their ability of referring, synthesizing and analyzing information was enhanced by PBL, and their skills both in written and oral were also improved. PBL made it easier to understand the contexts of course. lt was the best way to improve the effect of teaching in ophthalmology based on the increase of quality in novitiate that gives more chance to students of contacting with practice, developing the ability of clinical thinking and verifying the theory in clinical novitiate. Lots of teachers considered that the classroom atmosphere was more active, students were becoming more and more proactive on their classes and the relationship between students and teachers were more harmonious when PBL was used.
CONCLUSlON:Using PBL teaching mode can highly improve the teaching effectiveness of clinical epidemiology, which is worth popularizing.
