目的探讨慢性硬膜下血肿(CSDH)患者钻孔引流术后血肿复发的危险因素及其预测作用。方法回顾性分析2018年1月至2022年5月石河子大学第一附属医院神经外科收治的129例行钻孔引流术的CSDH患者的临床资料。随访3个月, 根据血肿是否复发将患者分为复发组与未复发组。比较两组患者的一般资料、与凝血功能相关的药物史和术前实验室检查指标、术前临床症状、手术前后血肿的影像学相关资料的差异, 对差异有统计学意义的指标(P<0.05)行多因素logistic回归分析。绘制受试者工作特征曲线(ROC)并计算曲线下面积(AUC), 评价相关危险因素对CSDH钻孔引流术后复发的预测作用。结果 129例患者中, 术后7~90 d共有24例(18.6%)血肿复发。单因素分析显示, 与未复发组(104例)比较, 复发组(24例)中女性、有吸烟史、发病时头晕、双侧血肿、血肿腔内有分隔患者的占比高, 有外伤史的占比低, 术前检查部分凝血酶原时间缩短、凝血酶时间延长、纤维蛋白降解产物含量高, 术后血肿引流量少、颅内积气量多, 上述指标差异均有统计学意义(均P<0.05)。多因素logistic回归分析显示, 性别(OR=24.19, 95%CI:1.98~295.01)、外伤史(OR=0.08, 95%CI:0.01~0.65)、吸烟史(OR=70.19, 95%CI:6.00~820.78), 术前纤维蛋白降解产物(OR=1.10, 95%CI:1.03~1.17)、部分凝血酶原时间(OR=0.43, 95%CI:0.22~0.86)、凝血酶时间(OR=5.13, 95%CI:2.05~12.85), 以及术后颅内积气量(OR=1.04, 95%CI:1.01~1.07)是CSDH钻孔引流术后复发的重要影响因素(均P<0.05)。由上述指标绘制的ROC的AUC为0.96(95%CI: 0.93~0.99), 最佳临界值为0.11, 预测CSDH钻孔引流术后复发的灵敏度为91.71%, 特异度为88.60%。结论性别、外伤史、吸烟史、术前纤维蛋白降解产物、术前部分凝血酶原时间、术前凝血酶时间及术后颅内积气量是CSDH钻孔术后复发的预测因素, 预测价值较高。

对大学生使用运动类APP的现状进行调查分析,了解大学生使用运动类APP的现状及运动类APP在大学生群体中的使用情况。调查结果显示:体育锻炼逐渐成为大学生的一种生活方式;运动类APP在大学生群体中占有率很高,且没有明显性别区分;大学生利用较短的碎片化时间进行体育锻炼;大学生使用运动类APP主要通过朋友推荐、新媒体传播、用户体验等途径;不同种类APP能满足大学生记录数据、运动指导、激发锻炼兴趣以及社交等不同需求;运动类APP存在监督作用差、运动技术指导不完善、与个人实际情况不符、数据记录不准确等问题。建议:对运动相关内容进行明确划分;通过多种途径对运动APP进行推广;有侧重性发展适用于大学生的健身、运动模块;设计独立的社交模块;巩固和完善运动类APP的基础功能。
