目的 血清同型半胱氨酸(Hcy)水平与慢性肾脏病(CKD)的进展相关,但中年人群的非线性关联研究较少,本研究旨在寻找慢性肾脏病危险因素。方法 本研究基于NHANES 1996—2006年数据,纳入5 361例45~65岁参与者,以估算肾小球滤过率(eGFR)<60 mL/(min·1.73 m2 )和尿白蛋白/肌酐比值(uACR)≥30 mg/g评估肾功能下降。结果 通过逻辑回归及平滑曲线拟合分析发现,Hcy每升高1 µmol/L,eGFR降低的风险增加8%(OR=1.08,95%CI:1.06~1.10),uACR升高的风险增加2%(OR=1.02,95%CI:1.00~1.04)。非线性分析显示,Hcy对eGFR的阈值效应拐点为13.4 µmol/L(拐点左侧OR=1.59,95%CI:1.49~1.70;右侧无显著关联)。亚组分析表明,性别、高血压、糖尿病等协变量无交互作用,然而,在敏感性分析中,糖尿病患者中Hcy与eGFR降低的关联更强(交互P=0.015 8)。结论 本研究提示,控制Hcy水平或可延缓美国中年人群(尤其是糖尿病患者)的肾功能衰退。
Objective Elevated serum homocysteine(Hcy)levels are linked to chronic kidney disease(CKD)progression,yet the nonlinear relationship in middle-aged populations remains underexplored.Methods This study analyzed data from 5 361 participants aged 45–65 years in the NHANES 1996–2006 cohort.Renal dysfunction was defined as an estimated glomerular filtration rate(eGFR)<60 mL/min/1.73 m2 and urinary albumin-to-creatinine ratio(uACR)≥30 mg/g.Results Logistic regression and smoothed curve fitting revealed that each 1 µmol/L increase in Hcy elevated the risk of reduced eGFR by 8%(OR=1.08,95% CI:1.06–1.10)and uACR by 2%(OR=1.02,95% CI:1.00–1.04).A nonlinear threshold effect was identified at 13.4 µmol/L,with a stronger association below this threshold(OR=1.59,95% CI:1.49–1.70)and no significant effect above it.Subgroup analyses showed no interactions with gender or hypertension,but a stronger Hcy-eGFR association was observed in diabetics(interaction P=0.0158).Conclusions These findings suggest that controlling Hcy levels may mitigate renal decline,particularly in diabetic populations,warranting further causal investigations.

目的 探讨谷氨酸对HT22细胞线粒体自噬和细胞凋亡的影响,并评估虾青素预处理的保护作用及其分子机制。方法 用谷氨酸及虾青素处理HT22细胞,通过蛋白印迹及聚合酶联反应等评估其对线粒体自噬的影响。结果 谷氨酸处理显著抑制线粒体初级自噬(PINK1、Parkin、pULK1ser555和LC3Ⅱ)和次级自噬(LAMP1和Rab7),上调cleaved Caspase-3的表达(P<0.05)。虾青素预处理减少细胞凋亡,恢复了线粒体自噬,PINK1、Parkin、pULK1ser555和LC3Ⅱ的表达水平上升(分别为2.3倍、2.6倍、83.3%及81.1%)(P<0.05),该作用被自噬抑制剂BafA1阻断。此外,谷氨酸抑制Nrf2核内转移和NLRX1表达,而预处理显著促进Nrf2的核内转移并上调NLRX1,分别上调25.8%、33.2%。生物信息学分析显示NLRX1启动子区域含有3个Nrf2结合位点,提示Nrf2通过调控NLRX1转录活性发挥作用。结论 文章揭示虾青素通过Nrf2/NLRX1通路激活线粒体自噬,展现神经保护作用。
Objective To explore the effects of glutamate on mitophagy and apoptosis in HT22 cells and evaluate the protective effects and molecular mechanisms of astaxanthin pretreatment.Methods HT22 cells were treated with glutamate and astaxanthin.The effects on mitophagy were assessed using Western Blot and PCR.Results Glutamate treatment significantly inhibited primary mitophagy(PINK1,Parkin,pULK1ser555 and LC3II)and secondary mitophagy(LAMP1 and Rab7)while upregulating cleaved Caspase-3 expression.Astaxanthin pretreatment notably reduced apoptosis and restored mitophagy,the expression levels of PINK1,Parkin,pULK1ser555 and LC3II were significantly upregulated(by 2.3-fold,2.6-fold,83.3% and 81.1% respectively,P<0.05),but this effect was blocked by the autophagy inhibitor BafA1.Additionally,glutamate suppressed Nrf2 nuclear translocation and NLRX1 expression,whereas astaxanthin promoted Nrf2 nuclear translocation and increased NLRX1 expression by 25.8% and 33.2%,respectively.Bioinformatics analysis revealed three Nrf2 binding sites in the NLRX1 promoter region,suggesting that Nrf2 may regulate NLRX1 transcriptional activity.Conclusions The study demonstrates that astaxanthin exhibited potential neuroprotective effect by activating mitophagy through the Nrf2/NLRX1 pathway.

Objective To explore the value of predicting liver disease complex adverse events in patients with liver cirrhosis by combining the degree of liver frailty with liver function grading,as a basis for identifying and intervening in adverse outcomes.Methods A study was conducted on 80 patients with liver cirrhosis admitted to the hospital from December 2022 to December 2023.Patients were followed up for six months to observe the occurrence of adverse events.Twenty-five patients with liver disease complex adverse events with two or more liver disease complications were selected as the observation group,and 55 patients with one or no liver disease complication were selected as the control group.The basic information,laboratory indicators,nutritional indicators,physical activity levels,liver frailty index(LFI),Child Turcotte Pugh(CTP)scores,univariate and multivariate Cox regression analysis were used to evaluate the risk factors for liver disease complex adverse events in liver cirrhosis patients.The value of combining LFI and CTP score in predicting liver disease complex adverse events in patients with liver cirrhosis was assessed by Receiver Operating Characteristic (ROC)curve area.Results The age,alanine aminotransferase(ALT),red blood cell count(RBC),hemoglobin(Hb),serum creatinine(Scr),total bilirubin(TBIL),walking speed,and calf circumference of the observation group were higher than those of the control group(t=4.235,6.500,3.826,3.989,4.289,8.878,2.474,all P<0.05).The nutritional risk of the observation group was 48.00%,LFI score≥4.5 was 52.00%,CTP grade B/C was 76.00%,which was higher than that of the control group at 18.18%,14.55%,and 27.27%(χ 2 =7.664,12.454,16.699,all P<0.05).Univariate Cox regression analysis showed age,nutritional risk,LFI ≥ 4.5,CTP grade B/C,RBC,Scr,TBIL,Hb,step speed and calf circumference were risk factors for the occurrence of liver disease complex adverse events in patients with liver cirrhosis(HR values=2.251,1.578,1.626,1.981,1.715,1.428,1.443,1.419,1.336,1.332,1.254,all P<0.05).Multivariate Cox regression analysis showed that age,ALT,nutritional risk,LFI ≥ 4.5,and CTP grade B/C were independent risk factors for liver disease complex adverse events in patients with liver cirrhosis(HR values=2.275,1.746,2.025,1.895,all P<0.05).The ROC curve results showed that the AUC of LFI,CTP,and LFI combined with CTP in predicting liver disease composite adverse events in patients with liver cirrhosis were 0.82,0.79,and 0.88,respectively(P<0.05).Conclusions Age,liver frailty,CTP grade B/C,and nutritional risk are risk factors for liver disease complex adverse events in patients with liver cirrhosis.The combination of LFI and liver function grade has higher efficacy in predicting liver disease complex adverse events in patients with liver cirrhosis.
