Objective: To analyze the clinical value and predictive difference of serum Golgi protein 73 (GP73) and serum autophagy-related protein p62 levels in the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure (ACLF). Methods: Clinical data of admitted cases to our hospital from October 2018 to April 2020 were retrospectively analyzed. Simultaneously, there were 32 cases with HBV-related ACLF in group A, 65 cases with hepatitis B virus-related cirrhosis in group B and C (Child-Pugh Class A, 34 cases as B group, and Child-Pugh B/C class, 31 cases as group C), and another 30 healthy subjects served as the control group (group D). The serum GP73 and p62 levels of the four selected groups were measured. ACLF group patients were followed up for 3 months to analyze the prognosis of the patients. The serum GP73 and p62 levels of patients who died and survived during hospitalization were compared. The data were analyzed by one-way analysis of variance, independent sample t-test, and Pearson's correlation analysis. Receiver operating characteristic curve (ROC) was used to analyze the predictive value of GP73 and p62 levels in surviving patients. Results: GP73 levels in the four groups A, B, C and D were (284.30 ± 70.55) ng/ml, (125.33 ± 20.57) ng/ml, (159.82 ± 31.20) ng/ml, and (45.46 ± 10.22) ng/ml, respectively. The p62 levels were (1.30 ± 0.35) ng/ml, (2.88 ± 0.58) ng/ml, (2.02 ± 0.545) ng/ml, and (4.68 ± 1.03) ng/ml, respectively. GP73 detection value was significantly higher in group A than the other three groups (P < 0.05). Group D had significantly lower value than the other three groups (P < 0.05), and group C had significantly higher value than group B (P < 0.05). The detection value of p62 in group A was significantly lower than the other three groups (P < 0.05). Group D had significantly higher value than the other three groups (P < 0.05), and group B had slightly higher value than group C, and the differences were statistically significant (P < 0.05). There was a negative correlation between GP73 and p62 (r = -0.695, P < 0.001). Survived patients GP73 level in the ACLF group was significantly lower than dead patients [(212.17 ± 22.47) ng/ml and (340.08 ± 32.91) ng/ml, t = 12.493, P < 0.05], and p62 level was significantly higher than dead patients [(1.46 ± 0.28) ng/ml and (1.18 ± 0.35) ng/ml, t = 2.445, P < 0.05]. According to the ROC curve analysis results, the area under the curve (AUC) of GP73 was 0.865, the AUC of p62 was 0.750, and the combined AUC of the both was 0.968. Conclusion: Both GP73 and p62 have a certain predictive value for the short-term prognosis of HBV-related ACLF patients, but the combination of the two indicators has a higher predictive value.
目的： 分析血清高尔基体蛋白73（GP73）和血清自噬相关蛋白p62水平对乙型肝炎病毒相关慢加急性肝衰竭（ACLF）患者短期预后的临床价值及预测差异。 方法： 回顾性分析本院2018年10月- 2020年4月收治的HBV相关ACLF患者32例的临床资料（A组），选择同期乙型肝炎肝硬化患者65例（其中Child-Pugh A级为B组34例、Child-Pugh B/C级为C组31例），另选同期健康体检者30名为对照组（D组）。测定四组入选者血清GP73与p62水平，对ACLF组患者随访3个月以分析患者预后情况；并比较死亡和生存患者入院时血清GP73与p62的水平。对数据进行单因素方差分析、独立样本t检验、Pearson相关性分析；采用受试者操作特征曲线（ROC）分析GP73与p62水平对生存患者的预测价值。 结果： A、B、C、D四组GP73水平分别为（284.30±70.55）ng/ml、（125.33±20.57）ng/ml、（159.82±31.20）ng/ml、（45.46±10.22）ng/ml；p62水平分别为（1.30±0.35）ng/ml、（2.88±0.58）ng/ml、（2.02±0.54）ng/ml、（4.68±1.03）ng/ml。GP73检测值A组显著高于其他三组（P < 0.05），D组显著低于其他三组（P < 0.05），C组显著高于B组（P < 0.05）。p62检测值A组显著低于其他三组（P < 0.05），D组显著高于其他三组（P < 0.05），B组略高于C组，差异有统计学意义（P < 0.05）。GP73与p62呈现负相关关系（r = -0.695，P < 0.001）。ACLF组中生存患者GP73水平显著低于死亡患者[（212.17±22.47）ng/ml与（340.08±32.91）ng/ml，t = 12.493，P < 0.05]；p62水平显著高于死亡患者[（1.46±0.28）ng/ml与（1.18±0.35）ng/ml，t = 2.445, P < 0.05]。据ROC曲线分析结果显示：GP73的曲线下面积（AUC）为0.865、p62的AUC为0.750，两项联合AUC为0.968。 结论： GP73与p62均对HBV相关ACLF患者近期预后具有一定预测价值，但两项指标联合预测价值更高。.
