?AIM: To study the changes of choroidal thickness and hemodynamic parameters in patients with diabetic retinopathy and their influencing factors.?METHODS: From January 2013 to January 2015, 100 patients (100 eyes) with type 2 diabetes were divided into 3 groups:34 patients without diabetic retinopathy ( NDR) , 36 patients with non proliferative diabetic retinopathy ( NPDR) group, and 30 patients with proliferative diabetic retinopathy (PDR). According to the results of OCT, the patients with diabetic retinopathy were divided into 2 groups: diabetic macular edema ( DME ) group ( 28 cases) , and 38 cases without diabetic macular edema. During the same period in our hospital 35 subjects for physical examination were selected as the control group. The hemodynamic parameters of the posterior ciliary artery in different groups of patients at different distance from the center of the macular were compared, analyzing influencing factors.?RESULTS:With the aggravation of diabetic retinopathy, the choroidal thickness in different distance from the center of the macular decreased. The choroidal thickness of NPDR and PDR group were thinner than that of the control group (P<0. 05). The choroidal thickness of NDR group was not different from the control group (P>0. 05). There was no significant difference in the choroidal thickness between the DME patients and non DME patients (P>0. 05). Pearson correlation analysis showed that there was no significant correlation between choroidal thickness of patients with diabetic retinopathy and diabetic duration, fasting blood glucose, HbA1c, eye axis length, systolic blood pressure and diastolic blood pressure (P>0. 05), but there was a correlation with BCVA (logMAR) (P<0. 01). EDV and PSV in NDR group and NPDR group were significantly lower than those in control group, RI was higher than that in control group. PSV and EDV in PDR group were significantly lower than those in other three groups, RI was higher than the other three groups, and the difference was statistically significant ( P<0. 05).?CONCLUSION:With the severity of retinopathy in type 2 diabetic patients, the choroidal thickness decreased, and the thickness of the choroid is beneficial in the comprehensive analysis of 2 diabetic retinopathy.

Objective Define the association of the catechol-O-methyltransferase(COMT) gene single nucleotide polymorphism(SNP) Ala22/72Ser with schizophrenia(SCZ) in Northern Han population.Methods In 506 SCZ patients,the genotype of Ala22/72Ser of COMT gene was sequenced and typing by polymerase chain reaction(PCR)-sequencing;the severity of psychiatric symptoms of SCZ patients was scaled by positive and negative syndrome scale(PANSS);the expression of COMT gene was determined by Real-Time PCR.Results In SCZ patients,the overall score of positive scale and general psychopathology scale were significantly increased in Ser and Ser/Ala carriers(P

Objective To investigate the protective effect of methylene blue (MB) on blood-brain barrier (BBB) injury after focal cere-bral ischemia-reperfusion in rats. Methods 18 male Sprague-Dawley rats were randomly divided into sham-operated group (n=6), model group (n=6) and MB treatment group (n=6). The left middle cerebral arteries were occluded for 1 hour and reperfused. MB was infused intra-venously immediately after reperfusion (3 mg/kg) and again 2 hours post-reperfusion (1.5 mg/kg), while normal saline was administered in the model group. The sham-operated group was treated as same as the model group without occlusion and infusion. HE staining was used to observe the histological injury in the cortex around the infarcted region 47 hours after reperfusion, while albumin immunohistochemistry was used to evaluate the permeability of the BBB, and immunohistochemistry and double immunofluorescence staining were used to exam-ine the expressions of glial fibrillary acidic protein (GFAP) and aquaporin-4 (AQP-4). Results HE staining showed that cells and blood ves-sels were not intact in the cortex around the infarcted region in the model group and they were better in the MB treatment group. The expres-sions of the albumin, GFAP and AQP-4 were higher in the model group than in the sham-operated group (P<0.01), and were lower in MB treatment group than in the model group (P<0.05). The double immunofluorescence staining showed the colocalization of GFAP and AQP-4 in the astrocytes. Conclusion MB may ameliorate the BBB disruption induced by focal cerebral ischemia-reperfusion through reducing glio-cyte proliferation and down-regulation of AQP-4 expression in rats.
