:1677-1683
 
       目的   探讨基于思维导图的绿色通道急救干预对急性心肌梗死患者介入治疗的效果。方法   对天津市人民医院2022年1月—2024年12月收治的80例AMI患者进行研究,依照收治时间进行分组,将2022年1月—2023年6月采取常规急救流程干预的40例患者分为常规组,将2023年7月—2024年12月的采取基于思维导图的绿色通道急救干预的40例患者分为思维导图组。比较两组患者急救效率、急救前后生命体征(心率、舒张压、收缩压)、心肌损伤指标[磷酸肌酸激酶(CK-MB)及肌钙蛋白Ⅰ(cTnI)],最后比较两组患者干预满意度。结果   对比急救效率发现,思维导图组的预检时间、会诊时间、导管室激活时间、急诊送至PCI手术时间均短于常规组(P<0.05);对比急救前后生命体征发现,与急救前对比,急救后两组的心率、舒张压、收缩压均降低(P<0.05),急救前后两组心率、舒张压、收缩压比较差异无统计学意义(P>0.05);对比急救前后心肌损伤指标发现,急救前两组CK-MB、cTnI比较差异无统计学意义(P>0.05),急救后,思维导图组CK-MB、cTnI低于常规组与急救前(P<0.05);对比干预满意度发现,思维导图组干预满意度为100.00%,高于常规组的85.00%(P<0.05)。结论  基于思维导图的绿色通道急救干预可提升AMI患者的急救效率,稳定患者生命体征,减轻心肌损伤的同时,提升患者干预满意度。
       Objective  To explore the effect of green channel emergency nursing based on mind mapping on percutaneous coronary intervention(PCI) of patients with acute myocardial infarction(AMI).Methods  A study was conducted on 80 AMI patients admitted to Tianjin People’s Hospital from January 2022 to December 2024.The patients were divided into two groups based on their admission time.The 40 patients who received routine emergency nursing interventions from January 2021 to June 2023 were assigned to the conventional group,while the 40 patients who  received green channel emergency nursing based on mind mapping from July 2023 to November 2024 were assigned to the mind mapping group.The emergency treatment efficacy,vital signs(heart rate,diastolic blood pressure,systolic bloodpressure),myocardial injury indicators(phosphocreatine kinase[CK-MB],and troponin I[cTn1])between two groups of patients before and after emergency treatment were compared.Results  The pre-examination time,consultation time,catheterization room activation time and emergency room to PCI operation time of mind mapping group were all shorter than those of conventional group(P<0.05).Compared with the vital signs before and after emergency treatment,we found that the heart rate,diastolic pressure and systolic blood pressure of the two groups decreased after emergency treatment(P<0.05),and there was no significant difference between the heart rate,diastolic pressure and systolic blood pressure of the two groups before and after emergency treatment(P>0.05).Comparing the myocardial injury indicators before and after emergency treatment,there was no significant difference in CK-MB and cTn1 between the two groups before emergency treatmentP>0.05).After emergency treatment,CK-MB and cTn1 in the mind map group were lower than those in the conventional group and before emergency treatment(P<0.05).Comparing the intervention satisfaction,it was found that the mind mapping group of 100.00% was higher than the conventional group of 85.00%(P<0.05).Conclusions  Green channel emergency nursing based on mind mapping can improve the efficiency of emergency treatment for AMI patients,stabilize their vital signs,reduce myocardial injury,improve patient intervention satisfaction.

:1651-1655
 
      目的   探讨妊娠期糖尿病(GDM)患者载脂蛋白B(Apo-B)、载脂蛋白A1(Apo-A1)水平在分娩巨大儿中的预测价值。方法   选取2023年1月—2024年1月在珠海市第五人民医院建档并进行孕检、分娩的85例GDM患者,按照分娩的新生儿体质量情况分为分娩正常组55例(新生儿体质量<4 000 g)和分娩异常组30例(新生儿体质量≥4 000 g)。比较两组孕妇一般资料及孕早期的Apo-B、Apo-A1、Apo-B/Apo-A1比值,采用受试者操作特征(ROC)曲线分析Apo-B、Apo-A1、Apo-B/Apo-A1对GDM患者分娩巨大儿的预测价值。结果   分娩异常组Apo-B水平、Apo_B/Apo_A1比值(1.05±0.15)g/L、(0.81±0.23)]高于分娩正常组(0.95±0.12)g/L、(0.65±0.18)](t分别为3.357、3.544,P<0.05);Apo-A1水平[(1.29±0.26)g/L]低于分娩正常组[(1.47±0.23)g/L](t=3.292,P<0.05);ROC曲线显示,Apo-B、Apo-A1水平及Apo-B/Apo-A1比值预测GDM患者分娩巨大儿的曲线下面积(AUC)分别为0.705、0.660、0.709,灵敏度分别为63.33%、63.33%、66.67%,特异度分别为72.73%、74.55%、76.36%,其中Apo-B/Apo-A1比值预测效能最高(P<0.05)。结论  GDM患者分娩巨大儿与孕早期Apo-B升高、Apo-A1水平降低密切相关,监测患者孕早期的Apo-B、Apo-A1水平及Apo-B/Apo-A1比值有助于临床对分娩巨大儿进行预测。

非小细胞肺癌干细胞靶点筛选及 NDC80 临床意义分析

Screening of stem cell targets for non-small cell lung cancer and analysis of clinical significance of NDC80

:1638-1650
 
      目的   通过生物信息学手段筛选非小细胞肺癌(NSCLC)中的关键靶点基因,识别预后标志物NDC80,并探讨其在NSCLC中的表达意义,进而分析NDC80作为NSCLC基因治疗靶点的可行性。方法   采用癌症基因组图谱(TCGA)TCGA数据库检索NSCLC相关数据,进行加权基因共表达网络分析(WGCNA)以识别关键基因,并进行差异表达分析、相关性分析和蛋白互作网络构建。对筛选出的关键基因进行功能分析。利用免疫组化染色法检测癌组织及癌旁组织中NDC80蛋白的表达水平,并进一步探究其与临床病理特征的关系。采用Kaplan-Meier法分析NDC80表达与NSCLC患者无进展生存时间(PFS)的关系。结果   共筛选出20个与NSCLC高度关联的关键基因,包括CDC20、CDK1、MCM4、CDC6、MCM2、PLK1、NDC80、CCNB1、CDC45、AURKA、MCM8、BUB1、CDT1、ORC1、CCNA2、CASC5、MAD2L1、BUB1B、CENPA、AURKB。免疫组化验证显示,NDC80蛋白在NSCLC组织中高表达,其在NSCLC组(阳性表达率88.6%)显著高于癌旁组(50.0%)(P<0.05)。NDC80蛋白的阳性表达率在TNM分期(Ⅲ期+Ⅳ期)、低分化、淋巴结转移的NSCLC组高于TNM分期(Ⅰ期+Ⅱ期)、高分化及中分化以及未发生淋巴结转移的NSCLC组(P<0.05)。NDC80蛋白的阳性表达率在不同性别、年龄、病灶大小分类的NSCLC组织中无显著差异(P>0.05)。Kaplan-Meier分析显示,NDC80蛋白高表达组的PFS中位数为(9.00±0.27)个月,明显低于低表达组(11.00±0.79)个月(P<0.05)。结论   本研究发现的关键基因在NSCLC干细胞的维持中发挥重要作用。免疫组化结果显示,NDC80蛋白在NSCLC组织中高表达,且与肿瘤分化、TNM分期及淋巴结转移密切相关。NDC80蛋白高表达组的PFS明显低于低表达组,提示NDC80可能成为NSCLC筛查、治疗和预后评估的潜在生物标志物。

Correlation of TRAF6,ChE and APACHE II scores with prognosis and predictive value in patients with septic shock

:1630-1637
 
       目的   探讨脓毒性休克患者肿瘤坏死因子相关受体6 (TRAF6)、胆碱酯酶(ChE)及急性生理学和慢性健康状况评价Ⅱ(APACHE Ⅱ)对预后不良的预测价值。方法   回顾分析2023年2月—2024年3月于某院ICU病区收治的226例脓毒性休克患者的临床资料,基于患者预后情况分为预后良好组(n=151)以及预后不良组(n=75)。回顾226例脓毒性休克患者入院时及治疗后的TRAF6、ChE表达变化,并记录患者APACHEⅡ评分和序贯器官功能衰竭评估(SOFA)评分动态变化;比较并分析两组患者详尽的临床资料,探讨TRAF6、ChE联合APACHE Ⅱ评分之间的关联性以及上述指标对脓毒性休克患者预后情况的临床评估价值。采用Logistic回归来分析对脓毒性休克患者生存状况产生影响的潜在因素。结果   多因素Logistic回归分析,年龄、APACHE Ⅱ评分、SOFA评分、机械通气时间、TRAF6与ChE表达水平均是影响患者预后的独立危险因素(P<0.05);受试者操作特征曲线分析显示,年龄、APACHE Ⅱ评分、机械通气时间、SOFA评分、TRAF6、ChE表达水平联合预测脓毒性休克患者预后不良的曲线下面积为0.925,高于单独检测的0.689、0.783、0.794、0.781、0.708、0.827。结论   临床需要及时识别高龄、长时间机械通气时间、高APACHE Ⅱ与SOFA评分、高TRAF6和ChE表达水平的高风险患者,TRAF6、ChE表达水平、SOFA评分、APACHE Ⅱ评分可作为评估脓毒性休克患者预后情况的临床指标,联合应用能进一步提升临床价值。
