摘要目的 研究多囊卵巢综合征(PCOS)患者血清中内脂素、超敏C反应蛋白(CRP)、单核细胞趋化蛋白-1(MCP-1)水平,为阐明PCOS的发病机制提供基础.方法 将94例PCOS患者和100例年龄与体重指数(BMI)相匹配的健康对照组,按BMI≥25 kg/m2或<25 kg/m2分为肥胖亚组和非肥胖亚组,采用酶联免疫吸附法(ELISA)和全自动生化分析仪检测其血清内脂素、CRP、MCP-1水平,并采用化学发光分析法检测其性激素水平以及内分泌代谢指标.结果 (1)PCOS组睾酮(T)、黄体生成素(LH)以及泌乳素(PRL)水平高于健康对照组(P<0.05～0.01),而卵泡刺激素(FSH)水平低于健康对照组(P<0.01).(2)PCOS肥胖亚组和非肥胖亚组内脂素、CRP、MCP-1、空腹胰岛素(FINS)、胰岛素抵抗指数(HOMA-IR)均分别高于健康对照组的肥胖亚组和非肥胖亚组(P<0.01).(3)PCOS组和健康对照组血清内脂素、CRP、MCP-1水平均与BMI、FINS、HOMA-IR呈正相关(r=0.323～0.675,P<0.01);在控制BMI后的偏相关分析显示,PCOS组血清内脂素水平与HOMA-IR呈正相关(r=0.491,P<0.01),PCOS组的MCP-1水平与LH呈正相关(r=0.267,P<0.05).结论 PCOS患者存在较高的内脂素、CRP和MCP-1水平,且内脂素水平与P-COS的胰岛素抵抗相关联.肥胖可能加重了PCOS的慢性炎症过程.

abstractsObjective To investigate the serum level of visfatin, C-reactive protein (CRP) and monocyte chemoattractant protein-1 (MCP-1) in patients with polycystic ovarian syndrome (PCOS), and provide the basis for understanding the pathogenesis of PCOS. Meth-ods 94 patients with PCOS and 100 healthy subjects were divided into 4 subgroups according to their body mass index(BMI), including obese PCOS subgroup(n = 52), non - obese PCOS subgroup (n = 42), obese healthy subject subgroup (n = 43) and non - obese healthy subject (n = 57). Serum visfatin, CRP, MCP-1, sex hormone levels and metabolic parameters were measured by enzyme-linked immu-nosorbent assay (ELISA), automatic chemistry analyzer or chemiluminescent immunoassay. Results Serum levels of testosterone (T), lu-teiizing hormone (LH) and prolactin (PRL) in the PCOS group were significantly higher than those in healthy subjects group(P <0.05～0.01), and follicle-stimulating hormone (FSH) levels were significantly decreased in PCOS group(P<0.01). Serum levels of Visfatin, CRP, MCP-1,fasting insulin(Fins) and insulin resistance homa model (HOMA-IR) in the obese or non - obese PCOS subgroup were signif-icantly increased than that in the obese or non - obese healthy subjects subgroup respectively (P<0.01). Pearson correlation analysis showed that the visfatin, CRP and MCP-1 levels were positively related to BMI, FINS and HOMA-IR(r=0.323～0.675, P<0.01). Par-tial correlation showed that serum visfatin levels were correlated with HOMA-IR(r=0.491, P<0.01), and serum MCP-1 levels were cor-related with LH (r=0.267, P<0.05) in the PCOS group. Conclusion The patients with PCOS had higher visfatin, CRP and MCP-1 lev-els, and visfatin levels were positively correlated with insulin resistance. Obesity were involved in the chronic inflammation course in patients with PCOS.
