目的 本研究旨在探讨2型糖尿病不同程度肾病与chemerin、SOD及MDA的相关性。方法 选取2016年1月—2017年12月期间于广州市第一人民医院内分泌科门诊和住院的患者100例,根据尿白蛋白/肌酐比(ACR)分为正常尿蛋白组(NA组,n=33),微量白蛋白尿组(MA组,n=34)及大量蛋白尿组(CA组,n=33),另选取32例我院体检中心体检结果正常的正常健康人作为对照组(NC组,n=32),测定血糖、糖化血红蛋白、血肌酐、ACR、24小时尿蛋白定量、胆固醇、甘油三酯、SOD、MDA、chemerin等水平。结果 SOD的水平:NC组> NA组> MA组>CA组(P<0.05);MDA的水平:CA组>MA组>NA组>NC组(P<0.05);Chemerin水平:CA组>MA组>NA组>NC组(P<0.05)。相关性分析提示ACR与血清SOD呈负相关,与MDA、chemerin呈正相关。多元回归分析显示,病程、胆固醇、糖化血红蛋白、chemerin是影响ACR的主要因素。结论 Chemerin、MDA、SOD可能参与糖尿病肾病的发生发展,检测其水平可以在一定程度上反映2型糖尿病肾病患者的病情严重程度。

Objective To explore the relationship between different type of Type 2 diabetes nephropathy and chemerin,SOD,MDA. Methods A total of 100 inpatients and outpatients were enrolled in this study between January 2016 and December 2017 in Guangzhou First People's Hospital. They were divided into normal urinary protein group (NA group, n=33), microalbuminuria group (MA group, n=34) and massive proteinuria group (CA group, n=33) based on ACR. Another 32 healthy people were collected as a control group in medical examination center (NC group, n=32). The levels of blood sugar, glycated hemoglobin, serum creatinine, ACR, 24-hour urinary protein, cholesterol, triglyceride, SOD, MDA and chemerin were measured. Results The level of SOD: NC group > NA group > MA group > CA group (P< 0.05). The level of MDA: CA group > MA group > NA group > NC group (P< 0.05). The level of chemerin: CA group > MA group > NA group > NC group (P< 0.05). Correlation analysis showed that ACR was negatively correlated with serum SOD and positively correlated with MDA and chemerin. Multivariate logistic regression demonstrated that course of disease, CHOL, HbA1c and chemerin were the main factors affecting ACR. Conclusion Chemerin, MDA and SOD may be involved in the occurrence and development of diabetic nephropathy. Chemerin, MDA and SOD may reflect the severity of type 2 diabetic nephropathy

目的 本研究旨在探讨血浆chemerin水平与原发性高血压合并心房颤动的相关性。方法 选择2016年2月—2017年12月期间在广州市第一人民医院心内科及老年心内科住院的高血压患者160例,根据是否合并心房纤颤分为心房纤颤组(AF组,n=72)及非心房纤颤组(NAF组,n=88),另选取140例我院体检中心体检结果正常的正常健康人作为对照组(CON组,n=140)。采用全自动生化检测仪测定甘油三脂、总胆固醇、低密度脂蛋白、C反应蛋白等生化学指标;使用ELISA法检测血浆chemerin水平。结果 AF组患者的血浆chemerin水平较NAF组患者升高[(180.45±15.23)ng/mL vs(162.36±13.44)ng/mL,P<0.05],且均较CON组升高[(142.36±11.83)ng/mL,P<0.05)],多元Logistic回归分析显示血浆chemerin水平与高血压病合并心房纤颤呈独立相关性(OR 1.112, 95% CI 1.023～1.302;P<0.001)。结论 高血浆chemerin水平可能是预测高血压合并心房纤颤的独立危险因素,血清chemerin可能成为一种预测高血压发生心房纤颤的重要生物学标记物。

Objective To explore the relationship between chemerin levels and permanent atrial fibrillation in patients with hypertension. Methods A total of 160 patients with hypertension were enrolled in this study. All the patients were classified as AF(n=72) or NAF(n=88) based on the permanent atrial fibrillation or not. And 140 healthy people were collected as a control group(CON). Triglycerides, total cholesterol, low density lipoprotein cholesterol and C-reactive protein were measured by automatic biochemical detector. Serum chemerin levels were determined by enzyme-linked immunosorbent assay(ELISA). Results Serum chemerin levels were higher in AF patients than those in NAF patients(180.45±15.23 ng/mL vs 162.36±13.44 ng/mL,P<0.05). They were both higher than that of the CON patients(142.36±11.83 ng/mL,P<0.05). Multivariate logistic regression demonstrated that chemerin level was independently associated with the permanent atrial fibrillation in patients with hypertension(OR 1.112, 95% CI 1.023～1.302;P<0.001). Conclusion Serum chemerin is an independent risk factor for permanent atrial fibrillation with hypertension. The results suggest that chemerin might be a useful biomarker for predicting the permanent atrial fibrillation with hypertension.

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.
