盆底超声参数与SUI患者肌纤维疲劳度和病情程度的相关性分析

目的 探讨盆底超声参数与压力性尿失禁(SUI)患者病情程度、肌纤维疲劳度的相关性.方法 选取2018年10月至2020年3月该院SUI患者146例为研究对象,均接受盆底超声检查并给予盆底肌训练.分析盆底超声参数[膀胱颈旋转角度(θ)、膀胱颈下移距离(X)、膀胱颈移动度(Mu)、膀胱尿道后角(α)]与SUI问卷评分(SS)、肌纤维疲劳度的相关性,以及分析其预测SUI疗效不佳的价值.结果 不同病情程度患者年龄、受教育程度、年收入、分娩方式、会阴情况、流产次数和X比较差异无统计学意义(P>0.05),BMI、既往分娩次数、新生儿体重、θ、Mu、α比较差异有统计学意义(P<0.05).SUI患者X与SS、盆底肌纤维疲劳度无显著相关性(P>0.05),θ、Mu、α与SS评分、盆底肌纤维疲劳度呈正相关(P<0.05).疗效良好者θ、Mu、α低于疗效不佳者(P<0.05);θ预测的曲线下面积(AUC)最大,临界值37.35°时,其灵敏度、特异度分别为94.74％、59.84％.结论 盆底超声参数中θ、Mu、α与SUI患者肌纤维疲劳度、病情程度存在良好线性关系.

Inverted U-Shaped Associations between Glycemic Indices and Serum Uric Acid Levels in the General Chinese Population: Findings from the China Cardiometabolic Disease and Cancer Cohort (4C) Study

Objective The relationship between serum uric acid(SUA)levels and glycemic indices,including plasma glucose(FPG),2-hour postload glucose(2 h-PG),and glycated hemoglobin(HbA1 c),remains inconclusive.We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.Methods The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study.A total of 105,922 community-dwelling adults aged≥40 years underwent the oral glucose tolerance test and uric acid assessment.The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.Results A total of 30,941 men and 62,361 women were eligible for the current analysis.Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels,but with different inflection points in men and women.The thresholds for FPG,2 h-PG,and HbA1 c for men and women were 6.5/8.0 mmol/L,11.0/14.0 mmol/L,and 6.1/6.5,respectively(SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes,while the inflection points were reached earlier in men than in women.     

Omics Approaches for Exploring Pneumoconiosis: A Review

Pneumoconiosis,a fatal lung disease caused by dust inhalation and deposition,is one of the leading occupational diseases worldwide[1].The dust is primarily inorganic particles,such as silica particles,coal dust,and asbestos fibers.If the diameter of dust is less than 5μm,it is defined as‘respirable dust’that can easily reach the distal airways and alveoli[2].     

Combined Effect of Smoking and Obesity on Coronary Heart Disease Mortality in Male Veterans: A 30-year Cohort Study

Objective Evidence is lacking regarding the combined effects of smoking and obesity on mortality from coronary heart disease in male veterans.This study aimed to explore the combined effect of smoking and obesity on coronary heart disease mortality in male veterans in China.Methods A cohort of 1,268 male veterans from 22 veteran centers in Xi’an(Shaanxi Province,China)were followed up once every 2 years from February 1,1987 to October 30,2016.The endpoint was death from any cause.The hazard ratio(HR)of each risk factor and the 95%confidence interval(CI)were calculated using a multivariate Cox proportional hazard model.Results The total follow-up was 24394.21 person-years;each subject was followed up for a mean duration of 19.24 years.By the end of the study,of the 1,268 veterans,889 had died,363 were alive,and 16 were lost to follow-up.Cox regression analysis results revealed that current smoking(HR:1.552,95%CI:1.074–2.243),obesity(HR:1.625,95%CI:1.024–2.581),and the combined effect of the two factors(HR:2.828,95%CI:1.520–5.262)were associated with coronary heart disease mortality.Conclusion Our results suggest that obese veterans who smoke might be an important target population for coronary heart disease mortality control.
