Objective To discuss the relationship between serum 25-hydroxy vitamin D[25(OH)D] level and the severity of diabetic retinopathy in type 2 diabetes mellitus.Methods 1474 cases of type 2 diabetic patients were classified into three groups according to their severity of diabetic retinopathy, the non-diabetic retinopathy group(NDR group, n =640), the background diabetic retinopathy group(BDR group, n =494) and the proliferative diabetic retinopathy group(PDR group, n=340).640 healthy people with normal level of glycosylated hemoglobin(HbA1c) were selected as control group(NDM group, n=640).Disease duration, body mass index(BMI), systolic pressure, low density lipoprotein-cholesterol(LDL-C), HbA1c and 25(OH)D were detected and compared among groups.Results Disease duration and HbA1c were increasing significantly, and the levels were NDM groupNDR group>BDR group>PDR group(all P<0.05).The level of 25(OH)D was negatively related to disease duration and HbA1c (P<0.001), and it was negatively associated to the severity of diabetic retinopathy(r=-0.855,P<0.001).Conclusion The decrease of 25(OH)D level is closely associated with the severity of diabetic retinopathy in patients with type 2 diabetes mellitus, and it might be an important predictor for the severity of diabetic retinopathy.

Objective To evaluate the efficacy and safety,particularly eye safety of hydroxychloro-quine(HCQ)treatment in primary Sj(o)gren's syndrome(pSS)patients.Methods Forty pSS patients were en-rolled and treated with HCQ 400 mg/day for 12 months.This is a prospective open-label study.Clinical mani-festations,clinical efficacy,biochemical and immunoserological parameters as well as ophthalmological exami-nations were investigated every three months to assess the safety and tolerability.Results There were signifi-cant decrease in the erythrocyte sedimentation rate(ESR),immunoglobulin G(IgG),immunoglobulin M (IgM)and rheumatoid factor(RF)level after 6 months treatment with HCQ(P＜0.01 or P＜0.05).No changewas detected in serum antinuclear antibody(ANA),anti-SSA/SSB antibodies after treated for 12 months.Somepatients had partial improvement in symptoms such as dry mouth,dry eyes and arthralgia.During the treat-ment,no significant effect on serum alanine aminotransferase (ALT),blood urea (BUN),serum creatinine (Cr),whole blood count(WBC)or hemoglobin(Hb)could be discovered.Central semus retinopathv(CSR)was found in one patient after 6 months treatment with HCQ.However,its association with HCQ could not be confirmed since it was not compatible with the usual HCQ retinopathy.Conclusion HCQ can improve svmp-toms of some pSS patients and can significantly decrease ESR,IgG,IgM and RF level.The safety profile of HCQ is generally good.However,ophthalmological examination before and after a 6-month interval may be necessary in long term HCQ treatment.

Objective: To investigate the level of mental health literacy among residents in Jiaxing City, Zhejiang Province, so as to provide insights into implementation of mental health education and improvements of the quality of mental health services. Methods: A total of 2 248 permanent residents at ages of 18 years and older were sampled using a multi-stage stratified random sampling method from 3 streets (townships) in Jiaxing City. Residents' demographics were collected using self-designed questionnaires, and the mental health literacy was investigated using the Mental Health Literacy Questionnaire. Factors affecting the achievement of the target of mental health literacy were identified among residents using a multivariable logistic regression model. Results: A total of 2 248 questionnaires were allocated and 2 172 valid questionnaires were recovered, with an effective recovery rate of 96.62%. The respondents included 1 075 men (49.49%) and 1 097 women (50.51%). There were 623 respondents that met the target of the mental health literacy (28.68%). Multivariable logistic regression analysis showed a higher possibility of achieving the target of mental health literacy levels among women than among men (OR=1.282, 95%CI: 1.047-1.570), among unmarried residents (OR=1.685, 95%CI: 1.018-2.788) than among married residents, among residents with educational levels of junior high school (OR=1.689, 95%CI: 1.168-2.441), high school/vocational high school/technical secondary school (OR=2.420, 95%CI: 1.601-3.658) and college or above (OR=3.543, 95%CI: 2.252-5.574) than among residents with an educational level of primary and below, among students (OR=2.572, 95%CI: 1.013-6.527), medical personnel (OR=3.330, 95%CI: 2.029-5.467), teachers (OR=2.909, 95%CI: 1.202-7.040), freelance/self-employed staff (OR=1.519, 95%CI: 1.100-2.098) and other professional technical personnel (OR=1.529, 95%CI: 1.012-2.310) than among workers. Conclusions The proportion of mental health literacy levels meeting the target is high among residents in Jiaxing City, and gender, educational level, occupation and marital status are factors affecting mental health literacy levels.

OBJECTIVETo determine the physiological role of D-bifunctional protein (DBP) in bile acid biosynthesis through investigating the effect of increasing activity of DBP on bile acid biosynthesis.

METHODSTwenty male Wistar rats were divided into two groups: diethylhexyl phthalate (DEHP) group (n = 10) and control group (n = 10). Serum triglyceride, total cholesterol, hepatic DBP activity, and fecal bile acids were assayed. The mRNA levels of hepatic peroxisome proliferator-activated receptor alpha (PPARalpha), DBP, and cholesterol 7alpha-hydroxylase (CYP7A1) were detected by RT-PCR.

RESULTSCompared with control group, serum triglyceride level was decreased significantly and PPARalphamRNA level was increased significantly in DEHP group (P < 0.01). Together with a sharp induction of DBP mRNA expression and DBP activity in DEHP group (P < 0.01), the levels of CYP7A1 mRNA and fecal bile acids were significantly increased by 1.9 times and 1.6 times respectively compared to control group (P < 0.01). There was a significantly positive correlation between DBP mRNA level or DBP activity and CYP7A1 mRNA level (r = 0.89, P < 0.01; r = 0.95, P < 0.01).

CONCLUSIONThe up-regulation of DBP mRNA and activity in liver can result in the increase in CYP7A1 mRNA expression and bile acid biosynthesis, suggesting that DBP may be involved in bile acid biosynthesis together with CYP7A1.

Objective To investigate the inlfuence of overexpression of miR-26b on the secretion of adipokines dur-ing human adipocyte differentiation. Methods Human preadipocytes were infected with the hsa-miR-26b over-expressing lentivirus and were induced to differentiate, and then the levels of adipokines (IL-6, leptin, resistin, TNF-α) at different time points during differentiation were measured by ELISA. Results Compared with control group, decreased secretions of both IL-6 and leptin, and increased secretion of resistin were found during the differentiation of human adipocytes in miR-26b overexpressed group. However, the secretion of TNF-αwas not measured in both groups. Conclusion The miR-26b can improve the inlfammation and insulin resistance of human adipocytes, which will provide potential targets for obesity treat-ment.

Objective It remains to be confirmed whether tissue kallikrein has neuroprotective effect in diabetes-induced stroke.This study was to investigate the neuroprotection of tissue kallikrein against cerebral ischemia-reperfusion injury in diabetic rats. Methods Healthy male SD rats were randomly divided into a sham operation, a saline control, and a tissue kallikrein group.Diabetes mellitus was induced in the animals by intraperitoneal injection of streptozotocin and the model of focal cerebral ischemia-reperfusion was made with an intraluminal vascular occlusion method. At 24 hours after modeling, we obtained the neurological deficit score, in-farct size, and brain water content, counted Iba1-and MPO-positive cells by immunohistochemistry, and determined the expressions of ICAM-1 and VCAM-1 by real-time PCR. Results In comparison with the saline controls, the rats treated with tissue kallirein showed significant decreases in the neurological deficit score (P<0.01), the infarct size ([23.57 ±5.79] vs [47.97 ±1.19]%, P<0.01), brain edema ([81.73 ±2.10] vs [84.94 ±2.34]%, P<0.05), the counts of Iba1-and MPO-positive cells (12.33 ±4.46 vs 31.83 ±8.13 and 13.83 ±4.49 vs 37.50 ±7.64, both P<0.01), and the expressions of ICAM-1 and VCAM-1 (both P<0.05). Conclusion Tissue kallikrein has a neuroprotective effect against cerebral ischemia-reperfusion injury in diabetic rats, which may be associated with its anti-inflammation property.
