基于 NHANES 数据库中年人群血清同型半胱氨酸水平与肾功能下降的阈值效应分析

Threshold effect of serum homocysteine level on kidney function decline among middle-aged adults in America based on NHANES database

:1061-1068
 
       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%CI1.06~1.10),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.

运动因子对心血管系统保护作用的研究进展

The protective effects of exerkines on cardiovascular system

:870-879
 
       运动可以调节机体代谢,预防和治疗由糖脂代谢紊乱所引发的心血管疾病。运动因子是在运动过程中,由肌肉、脂肪以及肝脏等多个组织合成和分泌的一系列生物活性物质,包括蛋白质和多肽类分子、小分子代谢物以及核酸等。诸多研究证实,运动因子是运动调节机体代谢的重要因素之一,也是机体从运动中获益的关键分子机制。近年来,随着蛋白质组学、代谢组学以及高通量测序等相关技术的飞速发展,越来越多的运动因子被陆续发现和证实。这不仅拓宽了人们对机体从运动中获益相关机制的认知,还激发了人们对运动因子在健康领域应用前景的浓厚兴趣。文章系统地阐述了运动因子对机体心血管系统的影响,旨在揭示运动因子在促进心血管健康以及治疗心血管疾病等方面的积极效用。

The effect of bevacizumab combined with chemotherapy on the levels of MSH2,MLHI,MSH6 and PMS2 in patients with advanced colorectal cancer

:809-814
 
       目的   分析贝伐珠单抗与化疗对晚期结直肠癌患者4种错配修复蛋白(MSH2、MLHI、MSH6、PMS2)水平影响。方法   选择2022年1月—2024年1月江苏省宿迁市中医院肿瘤科102例晚期结直肠癌患者,按抽签法分成两组,即化疗组及联合组,各51例。化疗组应用FOLFOX(亚叶酸钙+奥沙利铂+氟尿嘧啶)方案进行化疗,联合组采取贝伐珠单抗联合FOLFOX方案治疗。对比其肿瘤控制效果、免疫功能及MSH2、MLHI、MSH6和PMS2水平变化,并对比组间不良反应发生率。结果   联合组客观缓解率、疾病控制率高于化疗组(P<0.05);治疗后联合组患者CD4+ 、CD3+ 、CD8+ 、和CD4+ /CD8+数值高于化疗组,且两组治疗后均低于治疗前(P<0.05);治疗后两组患者MSH2、MLHI、MSH6和PMS2缺失率对比无统计学意义(P>0.05),但其阳性、阴性表达情况对比差异有统计学意义,联合组MSH2、MLHI、MSH6和PMS2阳性率低于化疗组(P<0.05);两组不良反应发生率对比差异无统计学意义(P>0.05)。结论   对晚期结直肠癌在化疗基础上增加贝伐珠单抗抗肿瘤效果显著,改善其免疫功能,虽无法改善患者错配修复蛋白缺损,但可辅助降低其阳性率,且不影响安全性。
