目的 初步研究2型糖尿病并视网膜病变患者的血浆趋化素(chemerin)水平及其与骨密度的关系。方法 选择150名糖尿病患者,按视网膜病变分为视网膜病变组(DR组)和眼底正常对照组(NDR组),采用全自动生化检测仪测定糖化血红蛋、甘油三脂、总胆固醇、低密度脂蛋白、高敏C反应蛋白;使用ELISA法检测血浆chemerin水平。骨密度采用双能X线骨密度仪分别测定腰椎正位(L2、L3、L4)、左侧股骨颈、大粗隆区、Ward's三角区的骨密度。结果 ①与NDR组相比,DR组的糖尿病病程较NDR组显著延长(P<0.05)。②DR组的TC、LDL-C、HbA1c、hs-CRP、chemerin水平较NDR组均显著升高(P<0.05)。③DR组的股骨颈、大粗隆区、Ward's三角区的骨密度较NDR组显著降低(P<0.05)。④血清chemerin水平与病程、BMI、HbA1C呈正相关,与股骨颈、大粗隆区、Ward's三角区的骨密度呈负相关。结论 DR患者的chemerin显著升高,chemerin可能参与DR的发生发展,并可能促使DR患者的骨密度降低。

Objective To explore the relationship between the circulation level of chemerin level and bone mineral density(BMD)in type 2 diabetes retinopathy patients. Methods A total of 150 patients with type 2 diabetes were selected. They were divided into two groups: retinopathy group(DR group), non- retinopathy group(NDR group). HbAlc, triglycerides(TC), total cholesterol(TG), low density lipoprotein cholesterol(LDL-C)and high-sensitivity C-reactive protein(hs-CRP)was measured by automatic biochemical detector. Bone mineral density was measured by the dual-energy X-ray absorptiometry. The BMD of lumbar vertebrae 2-4 and the left side of the femoral neck, the greater trochanter and Ward's triangle were assessed. Results ①Compared with the NDR group, the duration of diabetes in group DR was significantly longer(P<0.05); ②The levels of TC, LDL-C, HbA1c, hs-CRP and chemerin in DR group were significantly higher,③The BMD of the femoral neck, trochanter regionandward's triangle were significant reduction;④The level of chemerin was positively correlated with the duration of diabetes, BMI, HbA1C, and negatively correlated with the bone mineral density of the femoral neck, the greater trochanter, and the s' Ward triangle. Conclusion The level of chemerinin DR patients were significantly increased, and chemerin may play a role in the occurrence and development of DR, may promote the bone density decreased.

Objective To investigate the therapeutic effects and mechanisms of tetramethylpyrazine (TMP) on streptozocin(STZ)-induced-nephropathy in type 2 diabetic rats. Methods 50 SD rats were randomly divided into normal group(n=10) and model group(n=40). The model rats were fed on high fat and sugar diets for 4 weeks, then given STZ(40 mg/kg,ip). After 72 hours, the fasting blood glucose (FBG) was measured. Rats with high FBG above 16.67mmol/L were randomly divided into four groups: model, metformin(Met, 250 mg/kg)and TMP (80 mg/kg, 160 mg/kg) groups for treating 8 weeks, and both the control and model groups were given equals distilled water by intragastric administration. At the end of the experiment, blood glucose, urine protein, blood urea nitrogen and creatinine were measured. The expression of TLR4 and caspase3 protein in kidney tissue of rats was determined by immunohistochemistry. Pathological changes of kidney were observed under light microscope. Results Compared with the model group, metformin and high dose of TMP administered after 8 weeks, rats can significantly reduce the dynamic fasting blood glucose(P<0.05). Urinary protein excretion of total dynamic decreased significantly (P<0.01, P<0.05); the protein expression of TLR4 and caspase3 in the metformin group and high dose group was significantly lower than that in the model group (P<0.05); kidney tissue pathological damage was significantly reduced. Conclusion TMP has a protective effect on STZ induced nephropathy in type 2 diabetic rats, and its mechanism may be related to the down-regulation of TLR4 expression.

Objective To investigate the effects of metformin and glucagon like polypeptide -1 on fracture recovery in patients with type 2 diabetes mellitus(DM). Methods We selected 120 patients with type 2 diabetes mellitus from May 2016 to April 2017 in department of orthopedicsin in our hospital and randomly divided them into 5 groups, 24 cases in each group,includingthe low dose of metformin monotherapy group (A1), the high dose of metformin monotherapy group (A2), single drug GLP-1 group (B), and GLP-1 group low dose of metformin combination (C1) and high dose of metformin combination with GLP-1 group (C2). The low dose of metformin was 0.5 g / time, 2 times a day for oral administration. The high dose was 0.5 g / time, 4 times a day. Subcutaneous injection of liraglutide was once daily, starting at a daily dose of 0.6 mg, 1.2 mg daily after 1 week and 1.8 mg daily after another week. After an ideal level of blood glucose control, corresponding surgical procedures should be performed according to standard surgical methods and procedures. Diet control and other symptomatic treatments were also given. The femoral neck bone mineral density (BMD) and the Harris system score were examined at the first, third, and sixth month respectively. Results With the prolongation of treatment time, the BMD value and Harris system score in the A1 group, C1 group, C2 group were increased. After surgery in March and June, the BMD and Harris score of C1 group were higher than that of A1 group (P<0.05). The bone mineral density and Harris score of C1 group was significantly higher than that of group C2 (P<0.05). Conclusion Glucagon like peptide -1 may promote the fracture recovery and functional recovery in patients with type 2 diabetes mellitus, and with combination of low dose metformin is more effective than that with high dose metformin.

Objective To explore the periodontal disease occurrence and its factors for elderly type 2 diabetes patients, providing reference for comprehensive prevention and treatment measures. Methods 273 cases of elderly in-patients with type 2 diabetes in our hospital were enrolled. We checked their periodontal disease conditions, collected information including age, sex, educational level, body mass index, disease duration, smoking, fasting blood glucose, glycosylated hemoglobin, brushing habits. These values were compared between periodontal disease group and no periodontal disease group. Results People with periodontal disease in 273 cases of the object of study included 154 patients (56.41%), among them, gingivitis 60 cases, 94 cases of periodontitis. The teeth number was (18.54±6.31) for periodontal disease group on average, with (21.62 ±7.48) for no periodontal disease group (t=3.679, P<0.001). Older (P<0.001), longer course of disease (P<0.001), smoking (P<0.001), higher fasting blood glucose (P<0.001) and higher glycosylated hemoglobin (P<0.001) were risk factors of periodontal disease for elderly patients with type 2 diabetes. And well-educated (P=0.017), brushing teeth frequency > 1 / d (P<0.001), vertical brush mode (P=0.004), the use of dental floss (P=0.004) were the protective factors. Conclusion Periodontal disease prevalence is high in elderly patients with type 2 diabetes. The three level preventive measures should be strengthened to reduce the exposure of the periodontal disease risk factors.

目的 探讨2型糖尿病肾病(DN)患者肾组织中STOML2的表达及作用。方法 免疫组化检测临床2型糖尿病肾病患者肾组织STOML2的表达及定位,采用慢病毒转染方法建立稳定过表达STOML2的HK-2细胞系,并应用Western blot检测肾小管上皮细胞钙粘蛋白(E-cadherin)、Fibronectin和STOML2的表达。结果 STOML2在DN患者肾组织的肾小管上皮细胞胞浆中表达明显升高。在高糖刺激HK-2细胞建立的EMT模型中,STOML2呈时间依赖表达上调。STOML2稳定高表达时,E-cadherin表达下调,而Fibronectin明显上调,即能促进肾小管上皮细胞发生EMT。结论 STOML2可能通过促进肾小管上皮细胞向间充质细胞分化,进而参与糖尿病肾病肾脏纤维化的发生发展。

Objective To investigate the expression and role of STOML2 in renal tissue of patients with type 2 diabetic nephropathy. Methods To detect he expression and localization of STOML2 in clinical renal tissue in patients with type 2 diabetic nephropathy by immunohistochemistry, and use lentiviral transfection method to establish a stable cell line of over-expressing STOML2, lastly apply western blot to detect the expression of E-cadherin, Fibronectin and STOML2 in renal tubular epithelial cells. Results STOML2 was significantly increased in renal tubular epithelial cytoplasm of patients with DN. In the EMT model of HK-2 cells stimulated by high glucose, STOML2 was increased in a time dependent. Overexpression of STOML2 led to E-cadherin down-regulated, while Fibronectin up-regulated, which promoted the occurrence of EMT in renal tubular epithelial cells. Conclusion STOML2 may be involved in the development and progression of renal fibrosis in diabetic nephropathy by mediating epithelial- mesenchymal transition of renal tubular epithelial cells.
