Effects of steroid therapy on lymphocyte subsets and immune factors in children with primary nephrotic syndrome

:1103-1108
 
       目的   分析原发性肾病综合征(PNS)患儿在糖皮质激素(激素)治疗后淋巴细胞亚群及免疫因子的水平变化,以探讨PNS耐药机制。方法   选取PNS患儿共71例,正常对照组108例,收集PNS患者在激素治疗前、后及正常对照组儿童的淋巴细胞亚群[CD4+ 、CD8+ 、CD4+ /CD8+ 、CD19+ 和自然杀伤(NK)细胞]及免疫因子水平,并分析激素治疗后激素敏感患儿和激素耐药患儿相关指标的差异。结果  PNS患儿淋巴细胞亚群及免疫因子水平异常,激素治疗后PNS患儿总免疫球蛋白E(IgE)水平[767.50(270.25,1 937.50)IU/mL vs 311.00(62.70,757.00)IU/mL](P=0.008)下降,而CD4+ T细胞比例[(33.88±7.42)% vs(38.25±7.16)%](P=0.004)升高,激素治疗敏感患儿NK细胞比例高于激素治疗耐药患儿[(8.39±4.60)% vs(4.72±1.99)%](P=0.034),IgE水平低于耐药患儿[311.00(62.70,633.00)IU/mL vs783.00(88.05,1 290.00)IU/mL](P<0.001)。结论  PNS患儿淋巴细胞亚群分布及免疫球蛋白水平异常,激素治疗可影响患儿CD4+ T细胞比例及IgE水平,并且NK细胞比例和IgE水平与患儿激素耐药相关。

Correlation between islet β cell function and BMI in patients with long course type 2 diabetes

:1094-1102
 
       目的   探讨长病程2型糖尿病(T2DM)患者体质指数(BMI)与胰岛β细胞功能间的相关关系。法    选取2023年12月—2024年3月于承德市中心医院内分泌风湿免疫科住院的260例长病程(病程≥10年)T2DM患者作为研究对象,依据BMI将其分成正常组、超重组和肥胖组,比较三组间一般资料、检验学指标及检查的差异,分析胰岛β细胞功能与各指标间的相关性。结果   三组研究对象在空腹静脉血糖(FPG)、空腹C肽(FCP)、胰岛素抵抗指数(HOMA-IR)、尿酸(UA)、甘油三酯(TG)等上差异有统计学意义(P<0.05),在胰岛β细胞功能指数(HOMA-β)比较差异无统计学意义(P>0.05);肥胖组的FPG、FCP、HOMA-IR、UA、TG均高于正常组(P<0.05),超重组的UA、TG均高于正常组(P<0.05),肥胖组的FPG、HOMA-IR、UA高于超重组(P<0.05),Spearman相关分析结果显示HOMA-β与体质量指数(BMI)无相关性(r=0.046,P=0.461),HOMA-β与UA(r=0.226,P<0.001)、TG(r=0.148,P=0.017)呈正相关,HOMA-IR与BMI(r=0.279,P<0.001)与、UA相关(r=0.284,P<0.001)及TG(r=0.349,P<0.001)呈正相关,多元线性回归分析显示UA是HOMA-β的影响因素(P<0.05),BMI、UA、TG是HOMA-IR的影响因素(P<0.05)。论    长病程的T2DM患者,其胰岛素抵抗水平随着BMI的增加逐渐升高,而胰岛β细胞功能指数与BMI的相关性不显著。同时,UA和TG也是长病程T2DM患者胰岛β细胞功能的影响因素。
       Objective  To explore the correlation between body mass index(BMI)and islet β cell function in patients with long course type 2 diabetes mellitus(T2DM).Methods  A total of 260 patients with T2DM with a long course of disease(course≥10 years)admitted to the Department of Endocrinology and Rheumatology of Chengde Central Hospital from December 2023 to March 2024 were selected as the study objects,and were divided into normal group,overweight group and obese group according to BMI.Comparison among the three groups in general data,inspection index and and the difference of the islet β cell function were performed,and the correlation among the indexes was analyzed.Results  There were statistically significant differences in fasting plasma glucose(FPG),fasting C peptide(FCP),homeostasis model assessment-insulin resistance(HOMA-IR),uric acid(UA)and triglycerides(TG)among the three groups(P<0.05),but no statistically significant differences in homeostatic model assessment of β-cell function(HOMA-β)(P>0.05).The levels of FPG,FCP,HOMA-IR,UA and TG in the obese group were higher than those in the normal group(P<0.05);the levels of UA and TG in the overweight group were higher than those inthe normal group(P<0.05);the levels of FPG,HOMA-IR and UA in the obese group were higher than those in the overweight groupP<0.05).Spearman correlation analysis showed that HOMA-β was not correlated with BMI(r=0.046,P=0.461),but was positively correlated with UA and TG(r=0.226,P<0.001;r=0.148,P=0.017),HOMA-IR was positively correlated with BMI,UA and TG(r=0.279,P<0.001;r=0.284,P<0.001;r=0.349,P<0.001).Multiple linear regression analysis showed that UA was the influencing factor of HOMA-β(P<0.05),BMI,UA and TG were the influencing factors of HOMA-IR(P<0.05).Conclusions  In T2DM patients with long disease course,the level of insulin  resistance increased gradually with the increase of BMI,but the correlation between β-cell function index and BMI was not significant.At the same time,UA and TG are also factors affecting the function of islet β cells in patients with long-course T2DM.

:1069-1073
 
       目的   探讨单次根管疏通填充对牙体牙髓病患者的填充效果及龈沟液炎症指标的影响。方法   选择2023年8月—2024年2月天津市人民医院接收的牙体牙髓病患者84例进行研究,采用随机数字表法分为两组,各42例。对照组采取多次根管疏通填充,观察组采取单次根管疏通填充,比较2组填充效果、治疗效果、龈沟液炎症指标、口腔健康和功能指标、并发症情况。结果 观察组欠填、恰填、超填比例与对照组比较无统计学意义(χ 2 分别为0.262、1.615、0.512,P别为0.608、0.203、0.474)。观察组的总有效率为97.62%,高于对照组80.95%(χ 2 =6.098,P=0.014)。治疗后,观察组龈沟液白细胞介素IL-1β、IL-17A、IL-35、肿瘤坏死因子-α水平低于对照组(t分别为3.271、3.028、2.699、2.968,P分别为0.002、0.003、0.008、0.004)。治疗后,观察组龈沟出血指数、牙龈指数低于对照组,咬合力、咀嚼效率高于对照组(t分别为2.311、2.686、2.262、2.776,P分别为0.023、0.009、0.026、0.007)。观察组并发症发生率4.76%低于对照组21.43%χ 2 =5.126,P=0.024)。结论   牙体牙髓病采取单次根管疏通填充治疗可保证恰当的填充效果,取得良好的治疗效果,而且减轻龈沟液炎症反应,促进口腔健康和功能改善,并发症较少,安全性高,值得推广。

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.
