Objective To build relationship model of personality, life style and mental health for medical students. Methods 869 medical students were surveyed with Eysenk Personality Questionnaire, Symptom Check List 90(SCL-90), common condition questionnaire, to describe the situation of medical students mental health and personality, and a relationship model was set up by structural equation modeling. Results The situation of mental health for medical students was well. Male students showed significantly higher lie than female students. The only children showed significant higher lie than those having siblings. Neuroticism, life style, lie, sleep time everyday, boarding and lodging in middle school, friends, only child, degree of parents attention had significant direct influence on mental health (β =0.508, 0.136, 0.100, 0.082, 0.076, -0.057, 0.057, 0.051 ). Neuroticism, friends and sleep time everyday affected mental health in an indirect way through life style (β = 0.044, - 0. 008, 0.007). Only child affected mental health in an indirect way through boarding and lodging in middle school (β = -0.026). Lie affected mental health in an indirect way through neuroticism (β =0. 195). Conclusion The important effects of personality, life style on mental health are further supported in this study.

Hyperglycemia has direct and indirect impact on the occurrence and develop-ment of stroke. At present, hyperglycemia is considered as an independent risk factor for stroke. Hyperglycemia directly involves in cellular and vascular injury through activating polyol pathway, forming advanced glycosylation end product, activating protein kinase C and the hexosamine pathway. Moreover, hyperglycemia involves in vascular injury through the indirectly pathway such as lipid metabolism, glycosylated hemoglobin and insulin. Controlling hyperglycemia may effectively reduce the incidence of stroke and improve the prognosis in patients with stroke.

AIM: To investigate the expression of aquaporins-1 (AQP-1)in cultured bovine corneal endothelial cells and to explore the role of AQP-1 in corneal endothelial fluid transport.METHODS:The bovine corneal cells were cultured in DMEM containing 200mL/L neonate bovine serum. AQP-1 expression in the bovine corneal endothelial cells was detected with immunohistochemistry method before and after treatment of the cells with aquaporin inhibitor, p-chloromercuribenzene sulfonate. The osmotic water permeability was determined bymonitoring volume changes of cultured bovine corneal endothelial cells.RESULTS: AQP-1 expression in the membrane of cultured bovine corneal endothelial cells was revealed by positive staining (in brown color). The reading of osmotic water permeability of the cultured bovine corneal endothelial cells before treatment with p-chloromercuribenzene sulfonate was 0.044±0.005cm/s, which significantly decreased to 0.017 0.003 cm/s(n= 15) after treatment.CONCLUSION: AQP-1 expressed in the membrane of cultured bovine corneal endothelial cells may play an important role in fluid transport of corneal endothelial cells. Alteration of the AQP-1 expression may cause abnormal corneal function and corneal edema.

Background Researches showed that aquaporin-1 (AQP1) is closely associated with corneal neovescularization(CNV).Carbonic anhydrase inhibitor has the inhibitory effect on the AQP1 and further suppresses the CNV.However,the systemic adverse effect of Carbonic anhydrase inhibitor limit its clinical application.Therefore,the influence of topical carbonic anhydrase inhibitor on CNV is concerned.Objective Present study was to investigate the effects of topical carbonic anhydrase inhibitors on the expression of AQP1 in rat cornea after alkali burn and explore its role in corneal neovascularization (CNV).Methods The alkali-burn animal models were established in 60 eyes of 30 clean Sprague Dawley rats by putting the filter paper soaked 1 mol/L NaOH solution at the central cornea for 40 seconds.1％ Brinzolamide was topically administered in the 30 eyes of 15 models (Brinzolamide group),and the normal saline solution was used at the same way in other 30 eyes of 15 rats (model group).The 10 eyes of 5 normal Sprague Dawley received the eye drops of normal saline solution as the normal control group.The corneal burning degree was graded on the Mahoney ' s criteria in the third day,and Ee ' s method was used to score the opacification of cornea and the CNV area was analyzed in 3,5,7,10 days under the slit lamp microscope.The cornea tissue was obtained in the tenth day after burning for the observation of the pathology under the light microscope and the ultrastructure under the transmission electron microscope.The expressions of AQP1 and vascular endothelial growth factor(VEGF) in cornea tissue were detected using immunohistochemistry.The use of animals complied with the Statement of ARVO.Results No significant difference was seen in the scores of rat corneal alkali burn between the model group and brinzolamide group( t=0.97,P＞0.05 ).The scores of corneal edema and opacification and neovascular area were lower in brinzolamide group compared with model group ( t =2.18,P＜0.05 ;t =6.58,P＜0.01 ).The pathological and ultrastructural examinations showed less CNV and inflammatory cells in rat corneal tissue of the brinzolamide group in comparison with model group.The grey values of VEGF were 84.92±9.49 and 78.18± 11.41,and those of AQP1 were 88.01 ± 11.03 and 58.10 ± 12.14 in the model group and brinzolamidegroup respectively,showing statistically significant differences ( VEGF:t =2.48,P =0.02 ; AQPI:t =9.99,P =0.00 ).Conclusions 1％ Brinzolamide suppresses alkali burn-induced CNV by downregulating the expressions of AQP1 and VEGF in cornea in rat.

Kawasaki disease, also known as infantile skin mucous membrane lymph node syndrome, is an acute vasculitis syndrome in pediatricdepartment. The lesion mainly involves medium and small arteries, particularly the coronary artery, being a major cause of pediatric coronary lesion and also a potential risk factor of coronary heart disease during later adulthood. Here the clinical data and treatment of one case of Kawasaki disease complicated with coronary aneurysm and 4 years later the occurrence of cardiocerebrovascular lesion (CCVL) were retrospectively analyzed, and the related literatures were reviewed and analyzed to approach the clinical characteristics of this disease complications. It is suggested that at early stage regular treatment should be applied and afterwards periodical follow-up should be performed; long-term monitoring coronary changes ought to be carried out to decrease the occurrence of CCVL accident.
