Background::The ratio of high-density lipoprotein cholesterol (HDL-C) to low-density lipoprotein cholesterol (LDL-C) predicts cardiovascular disease (CVD) endpoints, yet its prognostic validity in high-risk populations and for type 2 diabetes mellitus (T2DM)-related adverse events remains unestablished.Methods::This study included 32,609 people aged 35-75 years in Fujian Province, China, who were at high risk for CVD. The primary endpoint was all-cause mortality during follow-up. Cox proportional hazard models and restricted cubic spline (RCS) analysis were used to evaluate the correlation between the HDL-C/LDL-C ratio and the endpoints.Result::On the basis of the restricted RCS curve, the participants were classified as having a low (< 0.3), middle (0.3-0.5), or high (> 0.5) HDL-C/LDL-C ratio. Multivariate Cox regression analyses revealed that the risk of all-cause mortality (HR = 1.48, 95% CI 1.14-1.93, p < 0.01 for low; HR = 1.30, 95% CI 1.06-1.58, p < 0.05 for high) was increased in the low and high groups. Participants without T2DM who were at high risk for CVD had similar prognoses (HR = 1.65, 95% CI 1.19-2.28, p < 0.01 for low; HR = 1.35, 95% CI 1.05-1.74, p < 0.01 for high). However, this association was not found in participants with T2DM who were at high risk for CVD. Conclusion::HDL-C/LDL-C can be used to predict the prognosis of individuals at high risk for CVD, and maintaining HDL-C/LDL-C ratios between 0.3 and 0.5 may be the most helpful range for this population. Furthermore, maintaining this ratio range holds clinical significance for cohorts without T2DM, although further exploration is needed in this T2DM cohort.

Objective To use analytic hierarchy process(AHP)-entropy weight method to evaluate the quality of symbiotic Armillaria in Gastrodia elata Bl.Methods The physiological,growth and chemical indexes of 6 strains of G.elata symbiotic Armillaria were used as evaluation factors,and the weight coefficients of each index were calculated by the AHP-entropy weight method.A comprehensive quality evaluation system was established to evaluate the quality of Armillaria strains,and the results were verified by red G.elata and hybrid G.elata combined planting experiments.Results The quality evaluation results showed that extracellular xylanase activity,extracellular cellulase activity and total sugar weight were relatively high,among which strains N6 and N3 ranked the top.The results showed that strains N5 and N4 combined with red G.elata had better quality,that strains N6 and N3 combined with hybrid G.elata had better quality.Conclusion The correlation of extracellular xylanase activity and total sugar of cellulase activity should be paid attention to in the quality evaluation of symbiotic Armillaria in G.elata.The quality evaluation system constructed in this artilcle is basically consistent with the results of hybrid G.elata combined with hybrid G.elata experiment,which can provide references for the quality screening of symbiotic Armillaria in G.elata.
