摘 要:目的目前关于血清betatrophin水平与糖尿病肾病(DN)的研究较少,文中旨在观察新诊断2型糖尿病(T2DM)患者血清betatrophin水平,探讨其与尿白蛋白肌酐比(UACR)的关系。方法选取2013年3月至2016年7月在江苏大学附属医院内分泌代谢科新诊断T2DM就诊患者90例,以及同期在体检中心体检的健康者60例(对照组),患者90例按UACR水平分为2组:UACR正常组(UACR<30 mg/g,n=60)、UACR异常组(UACR>30 mg/g,n=30)。采用酶联免疫吸附法测定血清betatrophin水平,采用免疫比浊法测定UACR,同时检测血糖、血脂等指标。结果 UACR异常组的betatrophin明显高于UACR正常组[(677.37±59.02)pg/m L vs(486.13±41.22)pg/m L,P<0.05]。T2DM患者血清betatrophin水平与年龄(r=0.246)、腰臀比(r=0.240)、空腹血糖(r=0.234)、餐后2 h血糖(r=0.363)、糖化血红蛋白(Hb A1c)(r=0.346)、空腹胰岛素(r=0.249)、胰岛素抵抗指数(HOMA-IR)(r=0.309)、血尿素氮(r=0.223)、血肌酐(r=0.277)及UACR(r=0.244)呈正相关(P<0.05),与肾小球滤过率(r=0.308)呈负相关(P<0.01);UACR正常组血清betatrophin与年龄、Hb A1c、UACR呈正相关(P<0.05);UACR异常组血清betatrophin与腰臀比(r=0.504)、餐后2 h血糖(r=0.600)、Hb A1c(r=0.449)、HOMA-IR(r=0.395)呈正相关(P<0.05)。肾小球滤过率、HOMA-IR、Hb A1c及腰臀比是血清betatrophin水平的影响因素。结论 T2DM合并蛋白尿患者的血清betatrophin水平的显著提高提示,betatrophin可能参与了DN的发生发展。Objective There are few researches for the serum betatrophin level and diabetic nephropathy (DN) recently. The aim of this study was to investigate the change of serum betatrophin level and the correlation of serum betatrophin and urinary albu- nfin-to-creatintine ratio (UACR) in patients with type 2 diabetes mellitus (T2DM). Methods A total of 150 Chinese subjects from Mar 2013 to Jul 2016 were enrolled in the study, including 90 patients with type 2 diabetes and 60 healthy controls. According to the level of UACR, the diabetic patients were divided into two groups:normal UACR group (UACR〈 30 mg/g, n = 60) and abnormal UACR group(UACR〉30 rag/g, n= 30). Serum betatropbin was measured by enzyme linked immunosorbent assay (ELISA). UACR was measured by turbidimetric inhibition immune assay. Blood glucose blood lipid were measured simultaneously. Results The ser- um betatrophin level was significantly higher in abnormal UACR group than that in normal UACR group [ 677.37±59.02 vs 486.13± 41.22 pg/mL, P〈O.05] ; Serum betatrophin level in T2DM patients was positively correlated with age (r= 0.246), waist hip ratio (WHR) ( r= 0.240), fasting blood glucose (FPG) ( r = 0.234) , 2 hour plasma glucose (2hPG) ( r = 0.363 ) , glycosylated hemoglo- bin ( HbA 1c) ( r = 0.346), fasting insulin (FINS) ( r = 0.249) , insulin resistance index (HOMA-IR) ( r = 0.309) , blood urea nitro- gen (BUN) (r=0.223), creatinine (CREA) (r=0.277) and UACR (r=0.244) (P〈0.05) ,and negatively correlated with glomeru- lar filtration rate (GFR) (r=0.308) (P〈0.01). Serum betatrophin level in normal UACR group was positively correlated with age, HbAlc and UACR (P〈0.05) ; Serum betatrophin level in abnormal UACR group was positively correlated with WHR (r--0.504), 2hPG (r=0.600), HbAlc (r=0.449), HOMA-IR (r=0.395) (P〈0.05). The WHR, HbAlc, HOMA-IR and GFR were the influ- ential factors of the serum beta
