Association between Baseline SBP/DBP and All-Cause Mortality in Residents of Shanxi,China: A Population-based Cohort Study from 2002 to 2015

Objective To investigate the association between blood pressure and all-cause mortality in Shanxi,China.Methods The‘2002 China Nutrition and Health Survey’baseline data in Shanxi province was used.A retrospective investigation was performed in 2015.The effects of SBP and DBP on the all-cause mortality were analyzed using the Cox regression model.The hazard ratio(HR)and 95%confidence interval(CI)were estimated by the sex and age groups.Results The follow-up rate was 76.52%over 13 years,while the cumulative mortality rate for all participants was 917.12/100,000 person-years.The mortality rose with an increasing SBP(χ_trend²=270.537,P<0.001)or DBP level(χ_trend²=57.240,P<0.001).After adjustment for the confounding factors,a significant association between mortality and high SBP(≥160 mm Hg)and high DBP(≥100 mm Hg),with adjusted HR ranging from 1.405-to 2.179-fold for SBP and 1.550-to 2.854-fold for DBP,was noted.Significant HRs for most DBP subgroups were found in>60-year-old participants.Males with DBP≥100 mm Hg had a significantly higher mortality,with an HR(95%CI)of 2.715(1.377–5.351).Conclusion Adults with SBP>160 mm Hg and DBP>100 mm Hg had a higher mortality risk.Sex and age difference was noted in both DBP and mortality risk.     

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.

Rapid Determination of Total Content of Five Major Anthraquinones in Rhei Radix et Rhizoma by NIR Spectroscopy

Objective To establish a new method with near-infrared(NIR) spectroscopy to determine the total content of emodin, chrysophanol, rhein, aloeemodin, and physcion. NIR was used in this study to provide rapid and nondestructive analysis results. Methods In the first place, HPLC was used to measure the total content of emodin, chrysophanol, rhein, aloe-emodin and physcion in Rhei Radix et Rhizoma(RR) as a reference. In the second place, the spectral regions, regression methods, pretreatment methods, and partial least squares(PLS) factors were compared to increase the feasibility of the model. In the last, the root mean square error of calibration(RMSEC), root mean square error of cross validation(RMSECV), root mean square error of prediction(RMSEP), and correlation coefficient(r) were used as assessment parameters. Results PLS with first derivative pretreatment in the ranges of 4242-5581 cm~(-1), 5885-6233 cm~(-1) and 6394-7011 cm~(-1) provided the best results. The RMSEC and RMSEP obtained were 0.134 and 0.226 respectively. The according determination coefficients of the quantitative model were 0.99 and 0.94. Conclusion NIR spectroscopy as a quick and nondestructive analytical method may be used to determine the total content of emodin, chrysophanol, rhein, aloeemodin, and physcion for the quality control of RR.     

线粒体复合体在肾脏疾病中的研究进展

肾脏是富含线粒体的器官之一,其正常运行依赖于线粒体氧化磷酸化(oxidative phosphorylation,OXPHOS)为细胞供能.线粒体复合体(mitochondrial complex,MC)构成了线粒体呼吸链(mitochondrial respiratory chain,MRC),具有电子传递和质子转移的功能,参与OXPHOS的过程.近年的研究表明,MC参与了肾脏疾病的发生发展,MC在不同的肾脏疾病中作用不尽相同.本文旨在系统综述MC的功能,总结其在急性肾损伤(acute kidney injury,AKI)、以糖尿病肾病(diabetic kidney disease,DKD)为主的慢性肾脏病(chronic kidney disease,CKD)、肾脏肿瘤、线粒体DNA(mtDNA)疾病等不同肾脏病领域中的作用,分析探讨MC作为新的靶点在肾脏疾病诊治中的潜在价值.
