目的 采用两样本孟德尔随机化以及Meta分析研究趋化因子C-X3-C基序配体1（CX3CL1）表达水平与系统性红斑狼疮（SLE）发病风险的因果关系。方法 获取CX3CL1表达水平与SLE的全基因组关联研究（GWAS）数据，将单核苷酸多态性（SNP）作为工具变量并选择敏感的SNPs进行分析。通过逆方差加权法（IVW）、加权中位数法（WM）、MR-Egger回归法进行两样本MR分析，以OR值评估CX3CL1表达水平与SLE之间的因果关系，并对结果进行异质性和多效性检验。最后利用R软件Meta包进行Meta分析。利用coloc包进行共定位分析。结果 纳入9个SLE作为结局变量，其中4个变量ebi-a-GCST90018917（OR=2.14，95%CI：1.50~3.06），ebi-a-GCST003156（OR=2.25，95%CI：1.00~5.06），ebi-a-GCST90014238（OR=3.02，95%CI：1.54~5.94），finn-b-SLE_NOS（OR=1.81，95%CI：1.01~3.22）表明CX3CL1表达水平与SLE之间存在因果关系。关于 OR 95% CI 的森林图显示 SLE 患者的CX3CL1表达水平显著高于健康人群（OR=1.87，95%CI：1.53~2.29，P＜0.001）。共定位分析结果提示CX3CL1表达水平和SLE表型之间有共享的遗传变异位点（rs170364）。结论 CX3CL1表达水平与SLE存在正向因果关系，CX3CL1表达水平的升高使得SLE的发病风险升高。
Objective To investigate the causal relationship between CX3CL1 levels and the risk of systemic lupus erythematosus（SLE）using two-sample Mendelian randomization and Meta-analysis methods．Methods Genome-Wide Association Study（GWAS）data for CX3CL1 levels and SLE were obtained．Single nucleotide polymorphisms（SNPs）were used as instrumental variables，and sensitive SNPs were selected for analysis．Two-sample Mendelian randomization was performed using the inverse variance weighted（IVW）method，weighted median（WM）method，and MR-Egger regression to evaluate the causal relationship between CX3CL1 levels and SLE，with OR values assessing this relationship．Heterogeneity and pleiotropy tests were conducted on the results．Meta-analysis was performed using the Meta package in R software，and colocalization analysis was conducted using the coloc package．Results Nine SLE outcomes were included as outcome variables，with four variables（ebi-a-GCST90018917［OR=2.14，95%CI：1.50-3.06］，ebi-a-GCST003156［OR=2.25，95%CI：1.00-5.06］，ebi-a-GCST90014238［OR=3.02，95%CI：1.54-5.94］，finn-b-SLE_NOS［OR=1.81，95%CI：1.01-3.22］）indicating a causal relationship between CX3CL1 expression levels and SLE．The forest plot for OR 95%CI showed that CX3CL1 expression levels in SLE patients were significantly higher than in healthy individuals（OR=1.87［95%CI：1.53-2.29］，P＜0.001）．Colocalization analysis suggested that there was shared genetic variation sites（rs170364）between CX3CL1 expression levels and SLE phenotype．Conclusions There is a positive causal relationship between CX3CL1 expression levels and SLE，with increased CX3CL1 levels elevating the risk of developing SLE．

非自杀性自伤行为（NSSI）是指个体在没有自杀意图的情况下，故意对自己身体进行伤害的行为。近年来，NSSI在全球范围内整体呈上升趋势，尤其在青少年群体中日益普遍，这与青少年的年龄特点、心理及生物学特征、社会压力等因素密切相关。有研究表明，NSSI是自杀行为的独立危险因素，不仅对青少年健康造成严重影响，也给家庭和社会带来了沉重的负担。因此，本文通过系统回顾NSSI相关文献，阐述其流行病学现况、影响因素和干预措施，旨在为早期识别高危人群、预防青少年NSSI行为的发生以及制定相应的干预策略提供科学依据。
Non-suicidal self-injury（NSSI）is the behavior in which an individual intentionally inflicts harm on his or her own body without suicidal intent．In recent years，NSSI has been on the rise globally，especially among adolescents，which is closely related to the age characteristics，psychological and biological characteristics，and social pressure．Some studies have shown that NSSI is an independent risk factor for suicidal behavior，which not only poses a serious impact on the health of adolescents，but also imposes a heavy burden on families and society．Therefore，this article systematically reviews relevant literatures on NSSI，mainly elaborating the epidemiological status，influencing factors and interventions．We aim to provide a scientific basis for the early identification of high-risk populations，the prevention of NSSI in adolescents and the development of corresponding intervention strategies

Objective To explore the mechanism of long non-coding ribonucleic acid metastasis - associated lung adenocarcinoma transcript 1（LncMALAT1）regulating enhancer of Zeste homolog 2（EZH2）through competitive combination with microRNA-506-3p（miR-506-3p）to affect the proliferation of bladder cancer．Methods A total of 92 pairs of bladder cancer tissues and corresponding adjacent normal tissues were collected from surgical resections between January 2023 and October 2024．The expression levels of LncMALAT1 and EZH2 were detected using Western blot and qRT-PCR．The patients were divided into poor group（n=34）and good group（n=58）according to their prognosis．Clinical data, such as gender, age, tumor diameter, vascular invasion, TNM stage, and distant metastasis were collected, and the relationship between LncMALAT1 and EZH2 and the prognosis of bladder cancer patients was analyzed with clinical pathological indicators．Through in vitro experiments, including qRT-PCR Western blot, plate cloning and EdU experiment were conducted to verify the effect of LncMALAT1 on EZH2 expression and bladder cancer cell proliferation．Bioinformatics technology was used to predict the interaction between LncMALAT1 and miR-506-3p, and qRT-PCR was used to verify the change of miR-506-3p expression after up regulating LncMALAT1 expression in bladder cancer cells．Results The univariate results showed that vascular invasion, TNM stage, distant metastasis, LncMALAT1 and EZH2 expression levels were related to the poor prognosis of bladder cancer patients, and the difference was statistically significant（all P<0.05）．The results showed that the expression of LncMALAT1 and EZH2 in bladder cancer was positively correlated．In vitro experiment results showed that after up regulating LncMALAT1 expression, EZH2 expression was significantly up-regulated, and the proliferation ability of bladder cancer cells was significantly improved（all P<0.05）．QRT-PCR validation showed that the expression of miR-506-3p was significantly down regulated after the expression of LncMALAT1 was up-regulated（P<0.05）, suggesting that LncMALAT1 could regulate EZH2 through competitive combination with miR-506-3p, thereby affecting the proliferation and progression of bladder cancer cells．Conclusions LncMALAT1 can promote the proliferation of bladder cancer cells by competitively combining with miR-506-3p to regulate EZH2, and then accelerate the proliferation of bladder cancer cells, which can provide a new potential target for the treatment of bladder cancer．
