摘要:

目的    探讨不同糖代谢状态与血小板活化指标—可溶性p选择素(sP-selectin)、可溶性CD40L(sCD40L)的关系,并进一步研究其影响因素。方法   分别选取正常对照组(NC组)、糖尿病前期组和2型糖尿病组(T2DM组)患者各30例,计算体质量指数(BMI),采集空腹静脉血测定血糖(FPG)、胰岛素(FINS)、甘油三酯(TG)、总胆固醇(TC)、低密度脂蛋白(LDL-C)、高密度脂蛋白(HDL-C)、糖化血红蛋白(HbA1C)等指标,酶联免疫法(ELISA)测定静脉血清中sP-selectin、sCD40L水平,计算稳态模型胰岛素抵抗评估指数(HOMA-IR)。结果   糖尿病前期组和T2DM组的sP-selectin和sCD40L较NC组明显升高(P<0.05)。sP-selectin的表达与FPG、TG、TC、LDLC、HOMA-IR呈正相关,与HDL-C呈负相关(P均<0.05),其中与TG和FPG的相关性更高(P<0.01); sCD40L与FPG、BMI、HbA1c呈正相关(P均<0.05),与TG、TC、HOMA-IR无明显相关性(P均>0.05)。结论   糖尿病前期及T2DM人群血清中sCD40L和sP-selectin水平已明显升高,提示血小板活化在糖尿病前期已启动。

Abstract:

Objective   To investigate the levels of platelet activation indexes including soluble P-selectin (sP-selectin) and soluble CD40L (sCD40L) in subjects with different glucose metabolisms, and analyze the influencing factors for further study. Methods   The study enrolled pre-diabetic, T2DM patients and normal controls (NC) with 30 subjects in each group. Body mass index (BMI) was calculated. Fasting plasma glucose (FPG), insulin (FINS), triglyceride (TG), total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C) and glycated hemoglobin (HbA1C) levels were measured. Soluble P-selectin and soluble CD40L in serum were measured by enzyme-linked immunosorbent assay. Moreover, HOMA-IR of insulin resistance was calculated by homeostasis models. Results   The sCD40L and sP-selectin levels in pre-diabetes and T2DM groups were significant higher compared with those of the NC group (P<0.05). The sP-selectin level was positively correlated with FPG, TG, TC, LDL-C and HOMA-IR (P<0.05), in addition, its correlation with TG and FPG was especially higher (P<0.01).But it was negatively correlated with HDL-C (P<0.05). Furthermore, the sCD40L level was positively correlated with FPG, BMI, and HbA1c (P<0.05). However, it was not associated with TG, TC and HOMA-IR (P>0.05). Conclusions   The sCD40L and sP-selectin levels significantly increase in pre-diabetic and diabetic subjects, which suggests platelet activation has occurred during the pre-diabetic stage.
