摘要

目的:以多囊卵巢综合征（polycystic ovary syndrome

PCOS）人群为研究对象

通过构建包含补体C3的胰岛素敏感性（insulin sensitivity

IS）评分模型

探索一种简便易行的方法对PCOS患者的IR进行评估。方法:纳入99名PCOS患者及116名年龄匹配的正常女性

测量人体参数及空腹血生化指标（胰岛素、hs-CRP、补体C3等）

计算稳态模型胰岛素抵抗指数（homeostasis model assessment of insulin resistance

HOMA2-IR）。对所有PCOS患者及其中20名正常对照行高胰岛素-正葡萄糖钳夹术

结果以M值表示。在PCOS组中

采用多元线性回归

以M值为应变量

以BMI、LDL-C、补体C3、超敏C反应蛋白、空腹血清胰岛素为自变量

建立IS评分（即M值的预测值）模型方程

用ROC曲线评估该模型诊断IR的价值。结果:IS评分=19.36-0.35×BMI-2.28×C3（R

=0.54

P=0.000）。IS评分和HOMA2-IR诊断PCOS患者IR的ROC曲线下面积分别为0.89（95%CI=0.82

.96）和0.75（95%CI=0.64

.86）

当IS评分=8.93时

其诊断PCOS患者IR的灵敏度和特异度分别为0.70和0.95

Youden指数0.63。当HOMA2-IR=0.47时

其诊断的灵敏度和特异度分别为0.60和0.88

Youden指数0.47。结论:包含补体C3的IS评分模型评估PCOS人群的IR具有较好的诊断价值。

Abstract

Objective:To establish a scoring model with complement C3 to evaluate insulin sensitivity(IS)in polycystic ovary syndrome(PCOS)population. Methods:Ninety-nine PCOS patients and 116 age-matched healthy women were included in this study. Anthropometric parameters and fasting biochemical indicators(including insulin

hs-CRP

complement C3

etc.)were determined and homeostasis model assessment of insulin resistance(HOMA2-IR)was calculated. All PCOS patients and 20 healthy controls underwent hyperinsulinemic-euglycemic clamp assay. The equation of IS score was established by multiple liner regression among PCOS patients

and the value of this equation for IR diagnosis was assessed according to the ROC curve. Results:The IS score=19.36-0.35×BMI-2.28 ×C3(R2=0.54

P =0.000). Areas under the ROC curve of IS score and HOMA2-IR were 0.89(0.83 to 0.96) and 0.75(0.64 to0.86)respectively. The sensitivity and specificity of IS score were 0.70 and 0.95

and Youden index equaled to 0.63. The sensitivity and specificity of HOMA2-IR were 0.6 and 0.88

and Youden index equaled to 0.47. Conclusion:IS scoring model with complement C3 is valuable for the diagnosis of IR in PCOS population.
