目的 研究SOCS6/STAT6通路在前列腺细胞炎性增殖作用中的调控作用。方法 使用人前列腺细胞株RWPE-1建立炎症模型,将细胞分为对照（CON）组和炎症刺激（INF）组,后者通过添加脂多糖（LPS）模拟炎症环境。采用ELISA检测白细胞介素-1β（IL-1β）-1β、白细胞介素-6（IL-6）和白细胞介素-8（IL-8）表达水平,蛋白免疫印迹法检测细胞因子信号抑制物-6（SOCS6）、信号转导和转录激活因子-6（STAT6）及磷酸化STAT6蛋白的表达水平。结果 经过LPS处理后,RWPE-1细胞中的SOCS6蛋白表达水平显著下降（P<0.01）,而磷酸化STAT6表达水平上升（P<0.01）。结论 SOCS6/STAT6通路可能通过调节炎症环境下STAT6的磷酸化水平,参与调节前列腺细胞的炎性增殖作用。

Objective To explore the regulatory role of SOCS6/STAT6 pathway in the inflammatory proliferation of prostate cells．Methods The human prostate cell line RWPE-1 was used to establish an inflammation model．Cells were divided into a control（CON）group and an inflammation-stimulated（INF）group,with the latter subjected to lipopolysaccharide（LPS）treatment to simulate an inflammatory environment．The expression levels of interleukin（IL）-1β、IL-6 and IL-8 were detected by ELISA,and the expression levels of suppressor of cytokine signaling 6（SOCS6）,signal transducer and activator oftranscription-6,（STAT6）,and phosphorylated STAT6 proteins were detected by Western blot．Results The results showed that after LPS treatment,the expression of SOCS6 protein in RWPE-1 cells significantly decreased,while the expression of phosphorylated STAT6 increased．Conclusions The SOCS6/STAT6 pathway may be involved in regulating the inflammatory proliferation of prostate cells by modulating the phosphorylation level of STAT6 under inflammatory conditions．

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．

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 in the normal group（P<0.05）;the levels of FPG,HOMA-IR and UA in the obese group were higher than those in the overweight group（P<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．

目的 本研究以脑卒中患者为研究对象,通过二代Illumina高通量测序平台对患者的粪便标本进行微生物群落多样性测序。选择物种丰度≥30%的24个门类（Phylum）作为肠道菌群的研究指标,进而研究肠道菌群与脑卒后抑郁（PSD）之间的相关关系。方法 以40位脑卒中患者的24个门类作为特征变量,抑郁组和对照组为二分类目标变量,建立以Logistic回归、随机森林、支持向量机和AdaBoost为基模型的Stacking分类模型。主成分分析方法作为该模型的特征选择方法选择恰当的主成分进行模型训练,通过二分类评价报告（precision、recall、f1-score）、ROC曲线和混淆矩阵等评价指标对其性能进行评价。结果 （1）通过差异性检验分析了两组（抑郁组和对照组）的基线一致（P<0.05）;（2）从Stacking模型融合的角度定量分析了影响脑卒中后抑郁情绪的具体肠道菌群。研究结果可知,放线菌门、拟杆菌门、变形菌门和酸杆菌门在PSD患者中均增加（P<0.001）;厚壁菌门,疣微菌门,绿弯菌门和软壁菌门在PSD患者中降低（P<0.001）。结论 以上菌群是影响脑卒中后抑郁患者情绪的主要影响因素,因此,在临床上通过恰当干预肠道菌群的变化来调节脑卒中后抑郁患者的抑郁水平,这为脑卒中后抑郁情绪的诊断和治疗方案提供科学依据。

Objective In this study,patients with stroke were selected as the research object,and the microbial community diversity of patients' stool samples was sequenced by the second-generation Illumina high-throughput sequencing platform． Twenty four phylum species with 30% species abundance were selected as indicators for the study of gut microbiota,and then the correlation between gut microbiota and post-stroke depression（PSD） was studied．Methods Taking 24 categories of 40 stroke patients as characteristic variables,depression group and control group as dichotomous target variables,a stacking classification model based on Logistic regression,random forest,support vector machine and AdaBoost was established．As the feature selection method of the model,principal component analysis selects the appropriate principal components for model training,and evaluates its performance through dichotomous evaluation reports（precision,recall,f1 score）,ROC curve and confusion matrix．Results The baseline of the two groups（depression group and control group）was consistent（P<0.05）through the difference test．From the perspective of stacking model fusion,the specific intestinal flora affecting post-stroke depression was quantitatively analyzed．The results showed that Actinobacteria,Bacteroidetes,Proteobacteria and Acidobacteria were significantly increased in PSD patients（P<0.001）,while Firmicutes,Verrucomicrobia,Chloroflexi and Tenericutes were significantly decreased in PSD patients（P<0.001）．Conclusions The above microbiota are the main factors affecting the mood of patients with post-stroke depression．Therefore,in clinical practice,we can adjust the depression level of patients with post-stroke depression by properly intervening the changes of intestinal microbiota,which provides a scientific basis for the diagnosis and treatment of PSD．

目的 评估无托槽隐形矫治应用在正畸拔牙患者中的效果及对牙根吸收、可溶性细胞间黏附分子-1（sICAM-1）的影响。方法 纳入2022年1月—2024年8月的70例正畸拔牙患者,按照治疗方法分组,即对照组（35例,给予固定矫治）、观察组（35例,给予无托槽隐形矫治）,评价组间牙根吸收情况、牙周指标、炎症因子、矫治时间。结果 治疗结束时,两组均出现牙根吸收情况,但是观察组无牙根吸收>3 mm病例,而对照组存在牙根吸收>3 mm、>4 mm病例,P<0.05。治疗前,两组牙周指标[龈沟出血指数（SBI）、牙龈指数（GI）、菌斑指数（PLI）]、炎症因子[白介素-1β（IL-1β）、sICAM-1]比较差异无统计学意义（P>0.05）。治疗后,两组SBI、GI、PLI、IL-1β、sICAM-1升高,且观察组SBI、GI、PLI、IL-1β、sICAM-1低于对照组（P<0.05）。与对照组比较,观察组矫治时间更长（P<0.05）。结论 对正畸拔牙患者进行无托槽隐形矫治,虽然治疗时间长,但是可以抑制牙根吸收,减轻炎症反应,提高牙周健康水平。

Objective To evaluate the effect of clear aligner treatment on orthodontic tooth extraction patients and its impact on root resorption and soluble intercellular adhesion molecule-1（sICAM-1）．Methods Seventy orthodontic extraction patients from January 2022 to August 2024 were included and divided into two groups according to treatment methods：a control group（35 cases,receiving fixed orthodontic treatment）and an observation group（35 cases,receiving clear aligner treatment）． The root resorption,periodontal indicators,inflammatory factors,and orthodontic treatment time between groups were evaluated．Results At the end of treatment,both groups showed root resorption,but there were no cases of root resorption>3 mm in the observation group,while there were cases of root resorption>3 mm and>4 mm in the control group,P<0.05．Before treatment,there was no difference in periodontal indicators（gingival bleeding index[SBI],gingival index[GI],plaque index[PLI]）,inflammatory factors（interleukin-1 β[IL-1 β],sICAM-1） between the groups,P>0.05．After treatment,SBI,GI,PLI,IL-1 β,sICAM-1 increased in both groups,but SBI,GI,PLI,IL-1 β,sICAM-1 were lower in the observation group,P<0.05．Compared with the control group,the observation group had a longer orthodontic treatment time,P<0.05．Conclusions Although the clear aligner treatment time for orthodontic extraction patients is longer,it can inhibit root resorption,reduce inflammatory reactions,and improve periodontal health．
