目的 探究血清多配体蛋白聚糖-1(SCD-1)与可溶性血管内皮生长因子受体-2(sVEGFR-2)表达水平在老年慢性心力衰竭患者预后评估的判定价值。方法 选取2023年1月—2024年3月珠海市第五人民医院检验科收治的110例老年慢性心力衰竭患者,检测其血清SCD-1和sVEGFR-2水平,对患者进行随访调查,了解其再次由于心力衰竭住院、心源性死亡的情况。运用多因素Logistic回归分析,探究老年慢性心力衰竭患者预后影响因素。结果 Logistic回归分析显示,心功能分级(OR=3.433,95%CI:0.934~6.431)、B型脑钠肽升高(OR=2.462,95%CI:0.861~4.765)、血清SCD-1升高(OR=3.795,95%CI:0.972~6.894)、血清sVEGFR-2升高(OR=3.842,95%CI:0.942~6.912)为影响老年慢性心力衰竭患者预后不良的重要因素(P<0.05);联合血清SCD-1和sVEGFR-2曲线下面积0.962与B型脑肽钠曲线下面积0.844,相较于单一SCD-1曲线下面积0.658、sVEGFR-2曲线下面积0.712明显偏高(P<0.05)。结论 经研究证实,老年慢性心力衰竭患者预后效果不理想,其血清SCD-1和sVEGFR-2监测水平异常升高,和老年慢性心力衰竭预后不佳存在关联性,可视为老年慢性心力衰竭患者判定预后效果的主要标志物。
Objective To investigate the prognostic value of serum syndecan-1(SCD-1)and soluble vascular endothelial growth factor receptor-2(sVEGFR-2)expression levels in elderly patients with chronic heart failure.Methods A total of 110 elderly patients with chronic heart failure admitted to our hospital were selected,with a time interval of January 2023 to March 2024.Serum SCD-1 and sVEGFR-2 levels were detected and follow-up investigations were conducted to understand their re hospitalization and cardiogenic death due to heart failure.Multiple logistic regression analysis was used to explore the prognostic factors affecting elderly patients with chronic heart failure.Results According to logistic retrospective analysis,heart function grading(OR=3.433,95%CI:0.934-6.431),elevated B-type brain natriuretic peptide(OR=2.462,95%CI:0.861-4.765),elevated serum SCD-1(OR=3.795,95%CI:0.972-6.894),and elevated serum sVEGFR-2(OR=3.842,95%CI:0.942-6.912)were important factors affecting the poor prognosis of elderly patients with chronic heart failure,with differences P<0.05.The area under the curve of combined serum SCD-1 and sVEGFR-2 was 0.962,and the area under the curve of B-type brain peptide sodium was 0.844,which was significantly higher than that of a single SCD-1 curve of 0.658 and sVEGFR-2 curve of 0.712,with a difference of P<0.05.Conclusions Research has confirmed that the prognosis of elderly patients with chronic heart failure is not satisfied,and their serum SCD-1 and sVEGFR-2 monitoring levels are abnormally elevated,which is related to the poor prognosis of elderly patients with chronic heart failure.It can be regarded as the main biomarker for defining the prognosis of elderly patients with chronic heart failure.
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。
Objective To investigate the expression levels and prognostic value of transcription factor E-box binding to zinc finger protein 1(ZEB1)and lysosomal associated membrane protein 5(LAMP5)in colorectal cancer tissues.Methods A total of 120 colorectal cancer patients admitted to a hospital from January 2018 to January 2020 were selected.Immunohistochemical staining was performed on the colorectal cancer tissues and adjacent tissues of all patients,and the positivity rates of ZEB1 and LAMP5 were compared.The expression levels of ZEB1 and LAMP5 in colorectal cancer patients with different pathological characteristics were compared.All patients were followed up for 4 years and divided into two subgroups based on the follow-up results,namely the poor prognosis group(n=35)and the good prognosis group(n=85).The general clinical characteristics and expression levels of ZEB1 and LAMP5 were compared between the two groups.Logistic regression analysis was used to evaluate the predictive value of ZEB1 and LAMP5 for the prognosis of colorectal cancer.Results The relative expression level of ZEB 1 and LAMP 5 in colorectal cancer tissues [(38.26±5.49),(26.77±3.85)] and the positive rate of ZEB 1 and LAMP 5(86.67%,72.22%)were significantly higher than that of adjacent tissues [(15.46±2.54),(8.04±1.59),23.33%,15.56%],the contrast difference was statistically significant(t=41.280,χ2=25.437;t=49.255,χ 2 =16.071;P<0.05).Relative ZEBI expression levels in different TNM stages [I-Ⅱstage(35.55±4.13),Ⅲ-Ⅳstage(42.32±4.75)],lymph node metastasis[Yes(44.37±4.28),No(35.84±3.77)],degree of tumor differentiation [hypodifferentiated(35.27±4.57),and middle or high differentiated (29.04±2.55)],those differences were statistically significant(t=-8.254,P<0.001;t=9.227,P<0.001;t=-7.797,P<0.001).The relative expression of LAMP 5 between different TNM stages [I-Ⅱstage(24.88±3.37),Ⅲ-Ⅳstage(29.61±2.57)],lymph node metastasis [yes(30.72±2.19),no(25.21±3.19)],degree of tumor differentiation [hypodifferentiated(24.57±3.62),and middle or high differentiated(29.04±2.55)],the contrast was statistically significant(t=-8.254,P<0.001;t=9.227,P<0.001;t=-7.797,P<0.001).There were no differences in gender,age,gross type,and tumor size between the good prognosis group and the poor prognosis group(P>0.05),while there were differences in TNM stages,lymph node metastasis,tumor differentiation degrees,ratio of ZEB 1 and LAMP 5(P<0.05).Logistic regression analysis showed that TNM stage,lymph node metastasis,ZEB 1 positive,and LAMP 5 positive were independent predictive factors of poor prognosis in colorectal cancer(P<0.05).Conclusions ZEB1 and LAMP5 are highly expressed in colorectal cancer tissues and closely related to the occurrence and development of colorectal cancer.ZEB1 and LAMP5 are independent prognostic factors for colorectal cancer,and they have the potential to become therapeutic targets for colorectal cancer.
目的 探讨老年营养风险指数(GNRI)与慢性阻塞性肺疾病者急性加重期患者预后的相关性。方法 选择贵州省六盘水水旷医院2019年1月—2022年1月收治的COPD急性加重期患者,根据GNRI值,分为正常营养组(GNRI>98)和营养不良组(GNRI≤98),应用生存曲线和Cox比例风险回归评估营养状况与死亡率之间的关联。结果 共纳入198例COPD急性加重期患者,正常营养组90例,营养不良组108例,营养不良发生率为54.5%;Kaplan-Meier曲线表明,营养不良组的全因累积死亡率更高(58.3% vs 35.0%,P<0.001)。Cox比例风险回归分析显示在未校正模型中,HR为2.31(1.25~4.28),P<0.001。在完全校正模型中,HR为2.48(1.37~4.51),P=0.005,提示与正常营养状况相比,营养不良与全因死亡风险升高相关。结论 GNRI低是COPD患者急性加重期全因死亡的独立危险因素。
Objective To investigate the correlation between elderly nutritional risk index(GNRI)and prognosis of patients with AECOPD.Methods Patients with AECOPD admitted to our hospital from January 2019 to January 2022 were selected and divided into normal nutrition group(GNRI>98)and malnutrition group(GNRI≤98)according to GNRI value.Survival curve and Cox regression were used to evaluate the association between nutritional status and mortality.Results A total of 198 patients with AECOPD were included in this study.According to GNRI scores,90 patients were in the normal nutrition group and 108 were in the malnutrition group,with malnutrition incidence of 54.5%.The Kaplan-Meier curve showed that the cumulative all-cause mortality was higher in the malnutrition group(58.3% vs 35%,P<0.001).Cox proportional hazard regression analysis showed that HR in the uncorrected model was 2.31(1.25-4.28),P<0.001.In the fully corrected model,HR was 2.4(1.37-4.51)and P=0.005,suggesting that malnutrition was associated with a significantly higher risk of all-cause mortalitycompared with normal nutritional status.Conclusions Low GNRI is an independent risk factor for all-cause death in AECOPD patients.
