Abstract:

Objective · To observe the change of serum complement C1q tumor necrosis factor-related protein1 (CTRP1) level and explore its relationship with serum adiponectin (APN) level in elderly male metabolic syndrome (MS) patients. Methods · Clinical data of 279 male objects (6090 years old) were analyzed retrospectively, serum CTRP1 and APN levels of all objects were tested by enzyme-linked immuno sorbent assay (ELISA). The patients were divided into three groups, i.e. 105 MS patients (MS group), 90 MS patients combined with hypertension (HMS group), and 84 non-MS patients (control group). All general information, including height, body weight, systolic blood pressure (SBP), diastolic blood pressure, fasting blood glucose, fasting insulin and serum three acyl glycerin (TAG) were recorded, in order to calculate body mass index (BMI) and homeostasis model assessment of insulin resistance (HOMA-IR). Results · Compared with the control group, serum CTRP1 levels of patients in MS group and HMS group both increased, and the latter was more obviously. Serum APN levels of patients decreased obviously in HMS group and MS group. The level of serum CTRP1 was negatively related with the level of serum APN. Conversely, serum CTRP1 level was positively related with blood glucose, BMI, SBP, TAG and HOMA-IR. Conclusion · The level of serum CTRP1 is elevated, while the level of serum APN declines in elderly male MS patients. The serum level of CTRP1 is even higher in HMS patients. Serum CTRP1 level is related to many risk factors of atherosclerosis.
