However, its pathophysiologic role in humans remains largely unknown. The aim of our study was to investigate the relationship between serum vaspin level and glucose metabolism or obesity in Chinese adults. Methods A total of 123 subjects, including 84 subjects with normal glucose tolerance （NGT） and 39 subjects with diabetes, were enrolled in this study. Anthropometric parameters, abdominal fat areas, plasma glucose concentration, serum insulin, lipids, and vaspin level were measured in each participant. Results Serum vaspin concentration was significantly higher in diabetic patients than that in NGT subjects （592 （438-695） pg/ml vs 380 （294-517） pg/ml, P=0.020） in women. In all participants, age, fasting plasma glucose concentration （FPG）, 2-hour post-load plasma glucose （PG2h）, hemoglobin Alc （HbAlc） and high-density lipoprotein cholesterol （HDL-c） significantly increased from the lower tertile to the higher tertile of vaspin. Univariate linear regression analyses revealed that vaspin level was only positively correlated with age （β=0.340, P=0.002） in NGT subjects. And vaspin was positively associated with FPG （β=0.365, P=0.023）, PG2h （β=0.526, P=0.001）, HbAlc （β=0.388, P=0.016）, and HDL-c （β=0.353, P=0.027）, while negatively with homeostasis model assessment of beta cell function （HOMA-β） （β=-0.361, P=-0.024） in diabetic patients. In stepwise multivariate regression analyses, age was independently associated with circulating vaspin in NGT subjects, whereas PG2h was an independent predictor of vaspin in diabetic patients. In addition, there was no significant difference of serum vaspin level between men and women. And no significant correlations between vaspin and body fat indexes were detected.

文摘目的分析多囊卵巢综合征(polycystic ovary syndrome,PCOS)患者血清丝氨酸蛋白酶抑制剂Vaspin、肿瘤坏死因子相关蛋白9(C1q/tumor necrosis factor-related protein-9,CTRP9)的水平及相关影响因素。方法将于本院2016年3月至2017年8月确诊的59例PCOS患者纳入观察组,按照体质指数(body mass index,BMI,≥28 kg/m^2定义为肥胖)将其分为观察A组(非肥胖,28例)和观察B组(肥胖,31例);另选取同期于本院行健康体检的60例健康女性纳入对照组,根据BMI分为对照A组(非肥胖,31例)和对照B组(肥胖,29例)。检测并对比四组受检者血清Vaspin、CTRP9水平,分析其一般情况及生化指标。结果观察组患者血清Vaspin水平明显高于对照组(P<0.05),CTRP9水平明显低于对照组(P<0.05)。Pearson相关性分析显示:PCOS患者Vaspin水平与其高密度脂蛋白胆固醇(HDL-C)及120~180分钟葡萄糖代谢率(M120-180)水平呈负相关(r分别为-0.20、-0.18;P_均<0.05),与BMI、总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、空腹胰岛素(FINS)、甘油三酯(TG)、总睾酮水平及腰围、稳态模型胰岛素抵抗指数(homeostasis model assessment of insulin resistance,HOMA-IR)水平呈正相关(r分别为0.21、0.19、0.20、0.20、0.19、0.21、0.19、0.21;P_均<0.05)。PCOS患者CTRP9水平与HDL-C、M120-180呈正相关(r分别为0.20、0.18;P_均<0.05),与BMI、TC、LDL-C、FINS、TG、总睾酮水平及腰围、HOMA-IR水平呈负相关(r分别为-0.21、-0.19、-0.20、-0.20、-0.19、-0.21、-0.19、-0.21;P_均<0.05)。结论与健康人群相比,PCOS患者血清Vaspin水平较高,CTRP9水平较低;BMI、TC、HDL-C、腰围、FINS、TG、总睾酮、HOMA-IR、LDL-C、M120-180与血清Vaspin、CTRP9水平均密切相关。
