非霍奇金淋巴瘤患者化疗后感染及平均住院日的影响因素分析

Factors influencing post-chemotherapy infections and length of hospital stay in patients with non-Hodgkin’s lymphoma

:1511-1518
 
       目的   探讨营养评估及炎症因子水平对非霍奇金淋巴瘤(NHL)患者化学治疗(化疗)后感染及平均住院日的影响。方法   回顾性分析接受R-CHOP治疗的NHL患者95例。通过受试者工作特征(ROC)曲线确定患者主观整体营养评估(PG-SGA)预测患者化疗后感染的界值。将患者分为PG-SGA<4组与PG-SGA≥4组,比较两组间营养及炎症相关指标的差异。采用单因素与多因素回归分析NHL患者化疗后感染及平均住院日延长的危险因素。结果  ROC曲线显示PG-SGA为3.5时,约登指数最大,预测NHL患者化疗后感染灵敏度为92%,特异度为11.1%。PG-SGA≥4组患者平均年龄、国际预后指数(IPI)及Ann arbor Ⅲ~Ⅳ期比例均高于PG-SGA<4组(P<0.05)。与PG-SGA<4组相比,PG-SGA≥4组患者白介素6(IL-6)及中性粒细胞与淋巴细胞比值(NLR)明显升高,且化疗后感染率及平均住院日≥5 d比例高于对照组P<0.05);与对照组相比,PG-SGA<4组患者前白蛋白、白蛋白和血红蛋白水平升高(P均<0.05)。多因素回归分析显示,PG-SGA≥4及合并糖尿病是NHL患者化疗后感染率的独立危险因素(P均<0.05)。白蛋白低于35 g/L及合并化疗后感染是NHL患者平均住院日延长的独立危险因素(P均<0.05)。结论   基于PG-SGA的营养评估及炎症因子分析对NHL患者化疗后感染及平均住院日的预测具有临床指导意义。

基于孟德尔随机化以及 Meta 分析方法评估 CX3CL1 表达水平与系统性红斑狼疮的因果关系

Causal relationship between CX3CL1 expression levels and systemic lupus erythematosus based on Mendelian randomization and Meta-analysis

:1491-1500
 
      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.

:1482-1490
 
       目的   初步探讨生长因子受体结合蛋白14(GRB14)在肺腺癌患者预后中的具体作用机制。方法   通过TIMER数据库、UALCAN数据库及GEPIA数据库,探讨GRB14 mRNA在肺腺癌及正常肺组织中的表达。运用免疫组织化学通过组织芯片(75例肺腺癌患者和75例癌旁组织)检测其蛋白表达水平,收集国外肿瘤研究团队上传至TCGA数据库229例肺腺癌患者的临床数据,分析评估GRB14在肺腺癌患者的表达及其临床特征及生存预后之间的关系。应用TIMER数据库对GRB14肺腺癌患者进行免疫浸润分析。String数据库探讨GRB14与其他蛋白之间是否存在相互作用。结果  TIMER数据库分析显示,相比正常组织,GRB14 mRNA在多种实体肿瘤和肺腺癌组织中高表达(P<0.05)。使用UALCAN数据库和GEPIA数据库以正常样本为对照组,肺腺癌患者的GRB14的表达均增加(P<0.01)。免疫组织化学检测组织芯片结果显示,GRB14蛋白在肺腺癌的表达高于正常肺组织(肺腺癌6.07±1.01 vs 癌旁组织4.80±1.22;P<0.01)。TCGA数据库分析显示,肺腺癌患者中GRB14高表达组和低表达组的中位总生存期分别为(41.59±5.20)月和(88.67±16.69)月;结合TCGA数据库绘制ROC曲线,发现GRB14的表达对肺腺癌患者具有一定的诊断价值。单因素回归分析结果显示,肿瘤分期(Ⅲ-Ⅳ)(P<0.01)、肿瘤原发灶的情况(T3-4)(P<0.01)、淋巴结转移(N1-3)(P<0.01)和GRB14表达(P<0.01)是影响肺腺癌中位总生存期的因素;Cox多因素回归分析显示,淋巴结转移(N1-3)(P<0.05)和GRB14表达P<0.01)是影响肺腺癌中位总生存时间的因素。TIMER数据库分析显示,GRB14 mRNA 表达与巨噬细胞(r=-0.164,P<0.01)、中性粒细胞(r=-0.175,P<0.01)和树突状细胞(r=-0.148,P<0.01)具有相关性。通过String数据库分析发现与GRB14相互作用的蛋白质包括EGFR、HRAS、FGFR1、INSR、CNGA1、COBLL1、LYPLAL1、TNKS2、TNKS、PRKCZ。结论  GRB14表达增加与肺腺癌患者预后不良相关。
       Objective  To assess the specific mechanism of growth factor receptor-bound protein 14(GRB14)in the prognosis of lung adenocarcinoma(LUAD)patients.Methods  The expression of GRB14 mRNA in LUAD and normal lung tissue was explored using TIMER database,UALCAN database,and GEPIA database.The expression of GRB14 protein was examined by immunohistochemistry using a tissue microarray.Then,the associations of GRB14 expression with clinicopathological features and clinical outcomes of LUAD were validated by analyzing TCGA database at the mRNA level and statistically evaluating the results.TIMER database was used to analyze immune infiltration of GRB14 in LUAD.Protein-protein interaction of GRB14 were analyzed using the String database.Results  Using the TIMER database,we found that GRB14 mRNA was highly expressed in various solid tumors and LUAD tissues compared to normal tissues(P<0.05).Comparing with the normal group,the expression of GRB14 was increased in LUAD(P<0.01)via using UALCAN database and GEPIA database.The expression level of GRB14 protein in the LUAD tissues was significantly higher than that in the noncancerous LUAD tissues(LUAD[6.07±1.01] vs benign,[4.80±1.22];P<0.01)in tissue microarray .Median overall survival in the high and low GRB14 expression groups in LUAD was(41.59±5.2)and(88.67±16.69)months respectively.We plotted the ROC curves of 3-year survival rate and 5-year survival rate which again suggested that the model had good predictive performance.Univariate analysis revealed that individual cancer stages(Ⅲ-IV)(P<0.01),tumor(T3-4)(P<0.01),lymph node metastasis(N1-3)(P<0.05)and GRB14 expressionP<0.01)were risk factors affecting the median overall survival time of LUAD.According to Cox multiple regression analysis,we found that lymph node metastasis(N1-3)(P<0.05)and GRB14 expression(P<0.01)were  risk factors affecting the median overall survival time of LUAD.Using TIMER database analysis,the mRNA level of GRB14 was significantly correlated with macrophages(r=-0.164,P<0.01),neutrophils(r=-0.175,P<0.01)and dendritic cells(r=-0.148,P<0.01).Through analysis of the String database,it was found that proteins that interacted with GRB14 including EGFR,HRAS,FGFR1,INSR,CNGA1,COBLL1,LYPLAL1,TNKS2,TNKS,PRKCZ.Conclusions  The results of the present study suggest that GRB14 may efficiently predict poor survival in LUAD patients.

青少年非自杀性自伤行为研究进展

Advances in the study of non-suicidal self-injury in adolescents

:1473-1481
 
       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
