银杏叶制剂联合地塞米松在老年突聋治疗中对血清炎症指标的影响

目的: 探讨银杏叶制剂联合地塞米松在老年突聋治疗中对血清炎症指标的影响。方法: 按随机数字表法将我院2016年7月-2021年7月收治的102例老年突聋患者分入两组（各51例）。对照组用地塞米松治疗，治疗组加用银杏叶制剂治疗。观察两组治疗前后纯音听阈和血管内皮功能指标[超氧化物歧化酶（SOD）、脂质过氧化物（LPO）、一氧化氮（NO）]、血清炎症指标[肿瘤坏死因子-α（TNF-α）、C反应蛋白（CRP）、白细胞介素-6（IL-6）]，分析其疗效与不良反应。结果: 与对照组比较，治疗组总有效率更高（96.08％vs 82.35％）（χ2=4.993，P=0.025）；两组治疗后各频率点阈值均下降，且相比对照组，治疗组治疗后各频率点阈值更低（P<0.05）；治疗后两组SOD、NO水平均升高，LPO水平降低（P<0.05），且相比对照组，治疗组治疗后SOD、NO水平更高，LPO水平更低（P<0.05）；治疗后两组血清TNF-α、CRP、IL-6水平降低，且相比对照组，治疗组TNF-α、CRP、IL-6水平更低（P<0.05）；治疗组不良反应发生率5.88％，对照组为9.80％，两组比较差异无统计学意义（P=0.543，χ2=0.461）。结论: 银杏叶制剂联合地塞米松治疗老年突聋患者疗效理想，能恢复各频率点听力，安全可靠，推测改善患者血管内皮功能和炎症因子水平是其重要作用机制。

Heart rupture as an acute complication of cocaine abuse: A case report

The purpose of this study is to show a very rare complication of acute cocaine poisoning, namely heart rupture. In the present case report, acute cocaine intoxication caused massive myocardial infarction, resulting in heart rupture and cardiac tamponade. A crime scene investigation found a dead body on the street in a drug dealing district. Examination of the body showed no external injuries. A thorough autopsy was performed showing massive cardiac tamponade with 510 ml of blood within the pericardium and full-thickness tissue lesion at the posterior wall of the left ventricle of 3.5 × 3 cm. Histological examination in hematoxylin and eosin was performed and confirmed the interruption of the posterior wall of the left ventricle with the presence of blood. In fact, although the correlation between cocaine and myocardial damage is well established, the relationship between heart rupture and acute cocaine intoxication is an extremely rare event. Moreover, since there are, to date, few reports of similar deaths, our report provides useful information regarding sudden death in a cocaine abuser. It is, therefore, of crucial importance to report this case to the scientific community.     

Assessing the utility of yearly pre-season laboratory screening for athletes on a major professional sports team

Objectives

Professional athletes undergo annual pre-season laboratory screening, although clinical evidence supporting the practice is limited and no uniform set of guidelines on pre-season laboratory screening exists. The aim of this study was to assess the clinical value of annual pre-season laboratory screening tests for a major professional sports team over multiple years.
