The role of ALBI combined with NLR in predicting liver cirrhosis complicated with esophageal and gastric varices bleeding

:387-392
 
       目的   探讨白蛋白-胆红素(ALBI)联合中性粒细胞与淋巴细胞比值(NLR)预测肝硬化合并食管胃底静脉曲张破裂出血(EGVB)的临床价值。方法   回顾性分析2021年1月—2022年12月肇庆市第一人民医院消化内科收治的80例肝硬化合并EGVB患者的临床资料,通过电话及门诊、再入院对其进行为期1年的随访,根据随访结果,将其分为2组,即存活组(n=69)与死亡组(n=11),分析导致患者死亡的危险因素,并评估ALBI联合NLR预测肝硬化合并EGVB患者死亡的临床价值。结果   死亡组的年龄60岁以上、腹水和肝性脑病者占比,总胆红素(TBiL)、NLR、凝血酶原时间(PT)、谷丙转氨酶(ALT)水平及ALBI评分均高于存活组(均P<0.05),而血红蛋白(HGB)、白蛋白(ALB)及血钠水平均低于存活组(均P<0.05);Logtisic回归分析显示,年龄60岁以上、腹水、肝性脑病和TBiL、NLR水平升高及ALBI分级为3级是肝硬化合并EGVB患者死亡的危险因素(均P<0.05);ALBI联合NLR预测肝硬化合并EGVB患者预后的准确率及灵敏度高于单一诊断,漏诊率低于单一诊断(P<0.05)。结论   肝硬化合并EGVB患者可见ALBI评分及NLR水平升高,而以上两种指标是患者死亡的危险因素,将其联合检测可评估患者预后,预测其死亡风险。
       Objective  To investigate the clinical value of albumin-bilirubin(ALBI)combined with neutrophil lymphocyte ratio(NLR)in predicting liver cirrhosis complicated with esophageal  and gastric varices bleeding(EGVB).Methods The clinical data of 80 patients with liver cirrhosis complicated with EGVB admitted to the Department of Gastroenterology of the First People’s Hospital of Zhaoqing from January 2021 to December 2022 were retrospectively analyzed.They were followed up for one year by telephone,outpatient service and readmission.According to the follow-up results,they were divided into the survival group(n=69)and the death group(n=11).The risk factors leading to the death of patients were analyzed and evaluated.Results  The proportion of age over 60,ascites and hepatic encephalopathy,the levels of TBiL,NLR,PT,ALT and ALBI in the death group were higher(P<0.05),while the levels of HGB,ALB and blood sodium were lower(P<0.05).Logistics analysis showed that age over 60,ascites,hepatic encephalopathy,NLR and ALBI grade 3 were independent risk factors for the death(P<0.05).The accuracy and sensitivity of ALBI combined with NLR in predicting their prognosis were significantly higher than that of single diagnosis,and the missed diagnosis rate was lower(P<0.05).Conclusions  ALBI scores and NLR levels significantly increase in patients with liver cirrhosis complicated with EGVB,and the above two indexes are risk factors for the death,and the combination of them can evaluate the prognosis of patients and predict the death risk.

ZEB1、LAMP5 在结直肠癌组织中的表达水平分析及预后预测价值分析

Expression levels and prognostic value of ZEB1 and LAMP5 in colorectal cancer tissues

:228-234
 
       目的  探讨转录因子E盒结合锌指蛋白1(ZEB1)、溶酶体相关膜蛋白5(LAMP5)在结直肠癌组织中的表达水平分析及预后预测价值。方法  选取驻马店市中心医院2018年1月—2020年1月收治的120例结直肠癌患者,分别采取所有患者的结直肠癌组织及癌旁组织进行免疫组化染色,对比ZEB1、LAMP5阳性率。对比不同病理特征结直肠癌患者ZEB1、LAMP5表达水平差异。对所有患者进行4年随访,依照随访结果将患者分为2个亚组,即预后不良组(n=35)和预后良好组(n=85),对比两组患者一般临床特征及ZEB1、LAMP5表达水平,应用Logistic回归分析ZEB1、LAMP5对结直肠癌预后的预测价值。结果 结直肠癌组织ZEB1、LAMP5相对表达量(38.26±5.49、26.77±3.85)与ZEB1、LAMP5阳性率(86.67%、72.22%)高于癌旁组织(15.46±2.54、8.04±1.59、23.33%、15.56%],对比差异有统计学意义(t=41.280,χ2=25.437;t=49.255,χ 2 =16.071;P<0.05)。不同TNM分期[Ⅰ~Ⅱ期(35.55±4.13)、Ⅲ~Ⅳ期(42.32±4.75)]、淋巴结转移患者[是(44.37±4.28)、否(35.84±3.77)]、肿瘤分化程度[低分化(35.27±4.57)、中高分化(41.34±4.60)]ZEB1相对表达量对比差异有统计学意义(t=-8.281,P<0.001;t=10.746,P<0.001;t=-7.253,P<0.001);不同TNM分期[Ⅱ期(24.88±3.37)、Ⅲ~Ⅳ期(29.61±2.57)]、淋巴结转移[是(30.72±2.19)、否(25.21±3.19)]、肿瘤分化程度[低分化(24.57±3.62)、中高分化(29.04±2.55)]患者LAMP5相对表达量对比差异有统计学意义(t=-8.254,P<0.001;t=9.227,P<0.001;t=-7.797,P<0.001);预后良好组与预后不良组患者性别、年龄、大体类型、肿瘤大小对比差异无统计学意义(P>0.05),预后良好组与预后不良组患者TNM分期、淋巴结转移、肿瘤分化程度、ZEB1、LAMP5阳性比例对比差异有统计学意义(P<0.05);Logistic回归分析显示:淋巴结转移、ZEB1阳性、LAMP5阳性为结直肠癌预后不良独立预测因素(P<0.05)。结论  ZEB1、LAMP5在结直肠癌组织中呈现高表达状态,且与结直肠癌的发生有关,同时ZEB1、LAMP5是结直肠癌预后的独立预测因素,两者有希望成为结直肠癌的治疗靶点。

膝骨关节炎患者术前衰弱列线图预测模型的建立

Establishment of a preoperative frailty nomogram prediction model in patients with knee osteoarthritis

:179-186
 
       目的   基于Nomogram初步构建膝骨关节炎(KOA)患者术前衰弱的风险预测模型。方法   便利选取172例于2021年12月—2022年8月在广州市某三甲医院关节外科接受择期膝关节置换术的KOA患者为研究对象,依据衰弱的发生与否分为衰弱组(n=111)和非衰弱组(n=61),通过单因素分析筛选变量,纳入Logistic回归分析,并构建列线图模型。结果   单因素分析结果显示年龄、BMI、膝关节疼痛年限、合并症、抑郁、焦虑、疼痛、睡眠障碍、营养状况等在不同组间比较差异存在统计学的意义(P<0.05)。多因素Logistic回归分析表明,BMI异常(OR=3.360)、膝关节疼痛年限>5年(OR=14.188)、抑郁(OR=5.608)、睡眠障碍(OR=25.480)是KOA患者术前衰弱的独立危险因素(P<0.05)。基于此,建立了预测膝骨关节炎患者术前衰弱风险的列线图预测模型。结果显示C-index为0.915,校正曲线接近理想曲线,ROC曲线下面积(AUC)为0.919(95%CI:0.878~0.961),可见该预测模型具有较好的区分度和准确度。结论   根据BMI、膝关节疼痛年限、抑郁以及睡眠障碍这四个独立危险因素,可以准确地预测膝骨关节炎患者术前衰弱的风险。
    Objective  To develop a nomogram for predicting the risk of preoperative frailty in knee osteoarthritis patients.Methods  A convenience sample of 172 patients who underwent elective knee arthroplasty at a Grade-A hospital in Guangzhou from December 2021 to August 2022 was selected.The patients were divided into two groups based on the presence of preoperative frailty:frailty group(n=111)and non-frailty group(n=61).The variables with statistical differences were screened by univariate analysis for multivariate logistic regression analysis,and the nomogram prediction model was established.Results  Univariate analysis identified significant differences between the groups in age,BMI,years of knee pain,complications,depression,anxiety,pain,sleep disturbance,and nutrition(P<0.05).Multivariate logistic regression showed that abnormal BMI(OR=3.360),years of knee pain > 5(OR=14.188),depression(OR=5.608),and sleep disorders(OR=25.480)were independent  risk factors for preoperative frailty in knee osteoarthritis patients(P<0.05).Based on these findings,a nomogram prediction model was established.Model verification results demonstrated that the nomogram had good differentiation and accuracy in predicting the risk of preoperative frailty,with a C-index of 0.915,an area under the ROC curve of 0.919(95% CI:0.878~0.961),and a calibration curve slope close to 1.Conclusions  The nomogram,based on four independent risk factors(BMI,years of knee pain,depression,and sleep disturbance),effectively predicts the risk of preoperative frailty in knee osteoarthritis patients.
