目的: 探讨住院新诊断男性2型糖尿病患者血浆总睾酮水平与骨钙素水平间的相关性。方法: 收集2018年1月至2020年6月间同济大学附属普陀人民医院收治入院的146例新诊断2型糖尿病男性患者（20~60岁）的临床资料及生化指标,将患者分为性功能正常及减退组,比较2组间的骨钙素水平;并将所有观察对象按骨钙素水平四分位数分为Q1组（<8.0 nmol/L）、Q2组（8.0~10.9 nmol/L）、Q3组（10.9~14.7 nmol/L）、Q4组（≥14.7 nmol/L）,比较组间的糖脂代谢及总睾酮水平差异,采用多元线性回归法分析骨钙素与总睾酮及其他指标间的相关性。结果: 58例（39.72%）男性2型糖尿病患者被诊断为性腺功能减,性腺功能减退组患者的骨钙素水平为（11.27±5.62） nmol/L,性腺功能正常组患者的骨钙素水平为（13.22±5.83） nmol/L,2组间的骨钙素水平差异有统计学意义（P<0.05）。随着骨钙素水平的升高,住院新诊断2型糖尿病男性患者的总睾酮水平升高(P<0.05)。Pearson相关分析显示,患者的骨钙素水平与总睾酮、血肌酐、血钙水平均呈正相关（P<0.05）。偏相关分析显示,在校正年龄、体质量指数（body mass index, BMI）、吸烟、饮酒、血肌酐、血钙、总胆固醇、甘油三酯、空腹胰岛素（fasting insulin, FINS）、糖化血红蛋白（glycosylated hemoglobin, HbA1c）、胰岛素抵抗指数（insulin resistance index, HOMR-IR）后,患者的骨钙素水平仍与总睾酮水平呈显著正相关（P<0.01）。Q4组患者的总睾酮及血钙水平较高,而BMI、HOMR-IR、空腹血糖和HbA1c较低。多元逐步回归分析显示,骨钙素是总睾酮水平的独立影响因素（β值为0.197,P<0.05）。结论: 住院新诊断2型糖尿病男性患者的血浆总睾酮水平与骨钙素水平呈正相关,本研究结果可为糖尿病男性患者性功能障碍的诊治提供参考。

Objective: To explore the relationship between plasma total testosterone and osteocalcin levels in males with newly diagnosed type 2 diabetes. Methods: A total of 146 males with newly diagnosed type 2 diabetes mellitus admitted from January 2018 through June 2020 were enrolled in the study. The patients were divided into four groups according to the level of osteocalcin: Q1 group (<8.0 nmol/L), Q2 group (8.0-<10.9) nmol/L, Q3 group (10.9-<14.7 nmol/L) and Q4 group (≥14.7 nmol/L). The parameters of glucose and lipid metabolism and total testosterone levels were compared among groups and multiple linear regression was adopted to analyze the relationship of osteocalcin, total testosterone and other indexes. Results: It revealed that 58 (39.72%) patients also had hypogonadism, with the level of osteocalcin decreased to (11.27±5.62) nmol/L, significantly lower than patients with normal gonadal function(13.22±5.83 nmol/L)(P<0.05). The total testosterone level in males with newly diagnosed type 2 diabetes increased along with osteocalcin (P<0.05). Pearson correlation analysis showed that osteocalcin was positively correlated with total testosterone, serum creatinine and serum calcium (P<0.05). Partial correlation analysis showed that after adjusting for age, body mass index (BMI), smoking, drinking, serum creatinine, blood calcium, total cholesterol, triglyceride, fasting insulin (FINS), glycosylated hemoglobin (HbA1c) and insulin resistance index(HOMR-IR), the level of osteocalcin was still positively correlated with total testosterone(P<0.01). Patients with higher osteocalcin had higher levels of total testosterone and blood calcium(Q4 Group), but lower BMI, HOMR-IR, fasting blood glucose and HbA1c. Multiple stepwise regression analysis revealed that high osteocalcin was an independent factor for elevated level of total testosterone (β value 0.197, P<0.05). Conclusions: Plasma total testosterone level is positively correlated with osteocalcin in newly diagnosed male patients with type 2 diabetes mellitus.
