[Abstract] Objective This paper tries to investigate the relationship on serum betatrophin concentration and islet beta cell function in patients with newly diagnosed obese type 2 diabetes mellitus (T2DM). Methods Totally 100 patients with newly diagnosed obese type 2 diabetes in the hospital from January 2014 to January 2015 were selected as the observation group and 100 healthy people at the same period were convenient selected as the control group. Anthropometrics and blood biochemical indexes of metabolism were measured, and serum betatrophin concentration was determined with ELISA. Correlation between betatrophin and anthropometrics and biochemical indexes was linear correlation analyzed. Results Serum betatrophin level was (422.5±247.60)pg/mL vs (316.3±293.30)pg/mL significantly increased in the observation group compared with healthy controls (P 1 资料与方法
1.1 一般资料
方便选取该院门诊或住院新诊断肥胖T2DM患者100例,男54例,女46例,年龄30~65岁,平均(54.25±8.84)岁,均符合1999年WHO诊断标准,按亚太地区(2000年)肥胖诊断标[3],体质指数(BMI)≥25 kg/m2为肥胖。另选择同期该院体检健康者(NGT)100名为对照观察,男47名,女53名,年龄32~63岁,平均(53.03±9.15)岁。排除标准:①合并糖尿病急性并发症或需胰岛素治疗者;②有严重心脑血管疾病或合并感染者;③严重心、肝、肾功能不全者;④妊娠或哺乳期妇女;⑤入选前3个月内服用过影响糖脂代谢药物者。两组研究对象例数、年龄、性别等基本资料比较,差异无统计学意义(P>0.05),具有可比性。
1.2 方法
询问病史,记录年龄、性别,检测血压,计算BMI,测量腰臀比(WHR)。受试对象隔夜禁饮食8~10 h后采集静脉血检测空腹血糖(FPG)、空腹胰岛素(FIns)、餐后2 h血糖(2 hPG)、餐后2 h胰岛素(2 hIns)、HbA1c、血脂谱(TC、TG、HDL-C、LDL-C)、肝肾功等。计算稳态模型胰岛素抵抗指数(HOMA-IR)及稳态模型胰岛β细胞功能指数(HOMA-β);并采用酶联免疫吸附实验(ELISA)法测定空腹血清betatrophin水平。
1.3 统计方法
用SPSS 18.0统计学软件进行正态性检验,正态分布的计量数据采用均数±标准差(x±s)表示,组间比较采用两独立样本资料的t检验,双变量相关性分析采用Pearson相关分析,Betatrophin的影响因素采用多元逐步回归分析。P参考文献]
