This multi-center, cross-sectional study investigated the association between serum testosterone （T） levels, serum sex hormone-binding globulin （SHBG） levels, and the risk of metabolic syndrome （MS） in 3332 adult Chinese men. The prevalence of MS was 34.7%, and men with MS had lower serum levels of total T （TT） and SHBG than those without MS （P 〈 0.001）. There was no significant difference in serum free T （FT） levels between subjects with and without MS （P = 0.627）. In logistic regression analysis, the association between MS and serum SHBG levels persisted after adjusting for age, body mass index （BMI）, smoking and drinking status, and serum TT （odds ratio [OR] 0.962, 95% confidence interval [95% CI] 0.954-0.969, P 〈 0.01）. However, the association between serum TT level and the risk of MS was weak after adjusting for age, BMI, SHBG level, and smoking and drinking status （OR 0,981, 95% CI 0.960-1.007）. Our study reveals that both serum TT and SHBG levels, but not serum FT, are inversely associated with the prevalence of MS and that serum SHBG is an independent and dominant risk factor for *** multi-center, cross-sectional study investigated the association between serum testosterone （T） levels, serum sex hormone-binding globulin （SHBG） levels, and the risk of metabolic syndrome （MS） in 3332 adult Chinese men.

目的:收集术前核磁共振成像(MRI)所得图像测量的尿路结构相关参数,探究其与腹腔镜根治性前列腺切除术(LRP)术后早期尿控的关联性,为术后发生尿失禁的高危人群筛选提供理论依据。方法:经严格的筛选后共纳入自2015年1月至2021年2月在首都医科大学附属北京同仁医院确诊为前列腺癌并行LRP的49例患者,患者年龄50~78岁,随访时间1年。术前通过收集患者完整资料,提取可能与术后早期尿控情况相关的临床数据,同时测量MRI图像所示可能与尿控相关的解剖结构参数,并收集术后早期患者尿控恢复情况的相关数据—尿垫使用数量。采用SPSS23.0对数据进行基础统计学分析,经单因素相关分析筛选可能相关因素(P<0.1),再采用R4.0.3或SPSS23.0对纳入的因素与尿控结果进行多因素Logistic回归分析。结果:MRI图像测量所得前列腺前后径长度为(4.0±1.11)cm;前列腺左右径长度为(4.6±0.83)cm;前列腺上下径长度为2.4~6.4 cm;膜部尿道长度(MUL)为(13.16±3.52)mm;尿道横纹括约肌厚度范围为1.08~4.37 mm。多因素分析结果显示年龄与术后1个月尿控是否恢复存在相关性(P=0.035,OR=0.16)。尿道横纹肌厚度与术后3个月(P=0.011,OR=0.02)、术后9个月(P=0.014,OR=0.039)、术后12个月(P=0.014,OR=0.039)尿控是否恢复存在相关性。对于术后12个月仍存在尿失禁的患者,尿道横纹括约肌小于或等于1.6 mm,尿失禁较为严重[P=0.010,OR(95%置信区间)=(0.858,6.240)]。MUL与患者术后9个月(P=0.024,OR=0.508)及12个月(P=0.024,OR=0.508)尿控是否恢复呈正相关。前列腺体积、前列腺各径线、以及研究过程中纳入的可能与术后尿控情况存在相关性的因素在分析过程中显示无明显统计学意义。结论:尿道横纹肌厚度与患者早期尿控是否恢复呈正相关,且尿道横纹括约肌越薄,患者尿失禁程度越严重。MUL与早期尿控是否恢复呈正相关。年龄是LRP术后1个月尿控是否恢复的独立危险因素。需要进行长期随访的前瞻性研究进一步证实上述初步结果。

Late-onset hypogonadism （LOH） has been described as a clinical syndrome comprising symptoms consistent with androgen deficiency and a circulating concentration of testosterone in the low-to-normal range in some middle-aged and elderly men. The presence of symptoms may affect the health and quality of life in aging men and it has become a hot spot in global medical research, diagnosis, and treatment in the recent years.
