目的 探讨尿液前列腺特异性抗原（u-PSA）预测老年良性前列腺增生（BPH）发生急性尿潴留（AUR）的价值。方法 选取东莞市中医院100例老年BPH患者（2020年1月—2021年4月）进行回顾性研究,均口服盐酸坦索罗辛+非那雄胺片治疗,随访1年,记录AUR发生情况,据此分为AUR组、非AUR组。比较2组一般资料,Logistic回归模型分析老年BPH发生AUR的危险因素,受试者工作特征（ROC）分析前列腺体积（PV）、u-PSA对老年BPH发生AUR的预测价值。结果 100例老年BPH患者AUR发生率为26%;AUR组u-PSA水平高于非AUR组,PV大于非AUR组（P<0.05）;Logistic回归模型分析,u-PSA水平及PV增高是老年BPH患者发生AUR的独立危险因素（P<0.05）;ROC曲线分析,u-PSA预测AUR的AUC=0.897,高于AUC_PV（P<0.05）。结论 u-PSA可作为老年BPH继发AUR的量化评估指标,有利于临床早期筛查、诊断,采取针对性干预措施,改善预后。

Objective To investigate the value of urinary prostate-specific antigen（u-PSA）in predicting acute urinary retention（AUR）in elderly patients with benign prostatic hyperplasia（BPH）．Methods A total of 100 elderly patients with BPH in our hospital（from January 2020 to April 2021）were selected for a retrospective study,all of whom were treated with oral tamsulosin hydrochloride + finasteride tablets,followed up for 1 year,and the occurrence of AUR was recorded．The patients were divided into AUR group and non-AUR group．The general data of the two groups were compared．Logistic regression model was used to analyze the risk factors of AUR in elderly BPH patients,and receiver operating characteristic（ROC）was used to analyze the predictive value of prostate volume（PV）and u-PSA for AUR occurrence．Results The incidence of AUR in 100 elderly patients with BPH was 26%;the level of u-PSA in the AUR group was higher than that in the non-AUR group,and the PV was greater than that in the non-AUR group（P<0.05）．Increased PV was an independent risk factor for AUR in elderly patients with BPH（P<0.05）．ROC curve analysis showed that the AUC of u-PSA for predicting AUR was 0.897,which was higher than that of PV（P<0.05）．Conclusions u-PSA can be used as a quantitative evaluation index for AUR secondary to BPH in the elderly,which is conducive to early clinical screening and diagnosing,and taking targeted intervention measures to improve prognosis.

目的 探讨体外循环手术前后患者血清HMGB₁、CK、CK-MB、LDH、LD₁、AST水平变化及意义。方法 采用ELISA法检测57例体外循环患者手术前后血清HMGB₁表达水平,采用临床常规方法检测血清中CK、CK-MB、LDH、LD₁、AST水平。对体外循环手术前后血清HMGB1表达水平与CK、CK-MB、LDH、LD₁、AST的水平进行比较与相关分析。结果 体外循环手术患者HMGB₁、CK、CK-MB、LDH、LD₁、AST水平在手术后0.5小时、24小时、48小时、72小时均高于手术前(P<0.05);HMGB₁、CK、CK-MB、LD₁、AST水平在手术后24小时达高峰,LDH水平高峰出现于手术后48小时,其他各指标渐渐下降。体外循环手术阻断时间延长,则HMGB₁、CK、CK-MB、LDH、LD₁、AST水平升高。体外循环手术后患者血清中HMGB₁表达水平与CK、CK-MB、LDH、AST指标呈正相关关系(P<0.05)。结论 体外循环手术后患者血清HMGB₁、CK、CK-MB、LDH、LD₁、AST水平升高,HMGB1参与了心肌的缺血再灌注损伤过程。

Objective To investigate before extracorporeal circulation and after HMGB₁, CK, CK-MB, LDH, LD₁, AST levels and significance in serum of patients. Methods 57 cases before extracorporeal circulation surgery and after, the levels of HMGB₁ were detected by ELISA,while the levels of CK and CK-MB and LDH and LD₁ and AST were detected by using conventional methods of clinical. Difference of HMGB₁ and CK, CK-MB, LDH, LD₁ and AST levels were compared. The relationship were been analyzed on the patients before extracorporeal circulation surgery and after. Results In extracorporeal circulation surgery, HMGB₁, CK, CK-MB, LDH, LD₁, AST levels after surgery in 0.5 hours, 24 hours, 48 hours,72 hours were higher than before surgery (P<0.05); HMGB₁, CK, CK-MB, LD₁, AST levels peaked at 24 hours aftersurgery, LDH levels was peaked at 48 hours after surgery, and then gradually declined. Extracorporeal circulation blocking was prolonged, the levels of HMGB₁ and CK and CK-MB and LDH and LD₁ and AST were elevated. After extracorporeal circulation surgery in serum the levels of HMGB₁ expression and CK,CK-MB,LDH, AST indicators showed a positive correlation(P<0.05). Conclusion The levels of HMGB₁, CK, CK-MB, LDH, LD₁ and AST were elevated after extracorporeal circulation surgery. HMGB₁ was involved in myocardial ischemia and reperfusion injury.
