Objective Previous studies on the association between lipid profiles and chronic kidney disease(CKD)have yielded inconsistent results and no defined thresholds for blood lipids. Methods A prospective cohort study including 32,351 subjects who completed baseline and follow-up surveys over 5 years was conducted.Restricted cubic splines and Cox models were used to examine the association between the lipid profiles and CKD.A regression discontinuity design was used to determine the cutoff value of lipid profiles that was significantly associated with increased the risk of CKD. Results Over a median follow-up time of 2.2(0.5,4.2)years,648(2.00%)subjects developed CKD.The lipid profiles that were significantly and linearly related to CKD included total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),TC/HDL-C,and TG/HDL-C,whereas low-density lipoprotein cholesterol(LDL-C)and LDL-C/HDL-C were nonlinearly correlated with CKD.TC,TG,TC/HDL-C,and TG/HDL-C showed an upward jump at the cutoff value,increasing the risk of CKD by 0.90%,1.50%,2.30%,and 1.60%,respectively,whereas HDL-C showed a downward jump at the cutoff value,reducing this risk by 1.0%.Female and participants with dyslipidemia had a higher risk of CKD,while the cutoff values for the different characteristics of the population were different. Conclusion There was a significant association between lipid profiles and CKD in a prospective cohort from Northwest China,while TG,TC/HDL-C,and TG/HDL-C showed a stronger risk association.The specific cutoff values of lipid profiles may provide a clinical reference for screening or diagnosing CKD risk.

Background::Studies have found that the ratio of total cholesterol to high-density lipoprotein cholesterol (TC/HDL-C) was associated with the development of chronic kidney disease (CKD). However, the relationship in different genders was rarely discussed. The aim of this study was to explore this relationship and assess its predictive power for both males and females.Methods::Based on a prospective cohort platform in northwest China, 32,351 participants without CKD were collected in the baseline and followed up for approximately 5 years. Cox proportional hazard model and restricted cubic spline regression analysis were performed to investigate the association between TC, HDL-C, TC/HDL-C and CKD in adult female and male. The clinical application value of the indicators in predicting CKD was evaluated by the receiver operator characteristic curve.Results::During a mean follow-up of 2.2 years, 484 males and 164 females developed CKD. After adjusted for relevant confounders, for every one standard deviation increase in TC, HDL-C and TC/HDL-C, the hazard ratios (HRs) and 95% confidence intervals (95% CIs) for CKD were 1.17 (1.05-1.31), 0.84 (0.71-0.99), and 1.15 (1.06-1.25) for males, 0.94 (0.78-1.13), 0.58 (0.35-0.95), and 1.19 (1.01-1.40) for females, respectively. The results also showed that TC, HDL-C, and TC/HDL-C were associated with CKD in a linear dose-response relationship. The TC/HDL-C had the largest area under the curve (AUC) compared to TC and HDL-C, and the AUC among the females was larger than that among males.Conclusions::The TC/HDL-C was significantly associated with CKD in adult males and females and has better clinical value in predicting CKD than TC and HDL-C, especially in females.

ObjectiveTo study the anxiety and depression status of the third-year junior high school students in Nanning city， and to discuss their relationships with test anxiety， so as to provide references for targeted psychological intervention for students. MethodsFrom May to June， 2021， a simple random sampling method was adopted to randomly enroll three classes of third-grade students from one junior high school in each district and county of Nanning city. The selected students were assessed using Test Anxiety Scale （TAS）， Self-rating Anxiety Scale （SAS） and Self-rating Depression Scale （SDS）. Thereafter， Pearson correlation analysis was conducted to explore the correlation among each scale score. ResultsA total of 2 080 students participated in the survey， and 1 826 （87.79%） valid questionnaires were collected. Among them， 999 students （54.71%） felt uncomfortable due to the test. Anxiety and depression were detected in 577 （31.60%） and 830 （45.45%） students， respectively. TAS score of female students was higher than that of male students ［（16.75±6.78） vs. （15.08±6.97）， t=-5.136， P<0.01］， SAS score of female students was higher than that of male students ［（46.05±10.43） vs. （44.16±10.87）， t=-3.769， P<0.01］， and SDS score of female students was higher than that of male students ［（52.34±12.44） vs. （49.98±12.17）， t=-4.039， P<0.01］. Correlation analysis showed that SAS and SDS scores were positively correlated with TAS score （r=0.574， 0.531， P<0.01）， and the correlation still existed after further controlling for age and gender （r=0.570， 0.526， P<0.01）. ConclusionThe third-year junior high school students in Nanning city suffer a high prevalence rate of anxiety and depression， and the two psychological states have positive relations with TAS. Furthermore， both anxiety and depression are more severe in female students than in male students.
