第三方库检测是Android应用安全分析领域的上游任务,其检测精度对于恶意应用检测、重打包检测、隐私泄露等下游任务有显著影响.为了提升检测精度和效率,采用相似性比较的思想,提出一种基于包结构和签名的第三方库检测方法,命名为***以流水线式模式组合主模块识别、第三方库候选识别和细粒度检测等3个组件.主模块识别方法区分主程序二进制代码与引入的第三方库二进制代码,旨在提升方法检测效率.在此基础上,提出由第三方库候选识别和细粒度检测构成的两阶段检测方法.前者利用包结构特征的稳定性来应对应用程序的混淆行为以提升混淆情形下的检测精度,并利用包结构签名完成快速比对以识别候选第三方库,达到显著降低成对比较次数、提升检测效率的目的;后者在前者涮选出的候选中,通过更细粒度但代价更高的相似性分析精确地识别第三方库及其对应的版本.为了验证方法的性能和效率,构建3个评估不同检测能力的基准数据集,在这些基准数据集上开展实验验证,从检测性能、检测效率和抗混淆性等方面对实验结果进行深入分析,结果表明LibPass具备较高的检测精度,检测效率,以及应对多种常用混淆操作的能力.

目的了解重症监护病房(ICU)医院感染与器械相关感染情况,为医院感染管理提供科学依据。方法收集2019年1月—2021年12月某三甲医院ICU住院患者医院感染监测数据并进行统计学分析。结果共监测2302例患者,发生医院感染120例(138例次),医院感染发病率为5.21%,发病例次率为5.99%。2019—2021年各年度医院感染发病率、发病例次率比较,差异均无统计学意义(均P>0.05)。医院感染部位以下呼吸道(96例次,69.57%)为主,其次是泌尿道(28例次,20.29%)和血液(6例次,4.35%)。共分离病原菌125株,以革兰阴性菌为主,占比74.40%。中央导管相关血流感染(CRBSI)、导尿管相关尿路感染(CAUTI)、呼吸机相关肺炎(VAP)日发病率依次为0.34‰、1.47‰、8.65‰,三年间器械相关感染发病率下降,VAP下降明显(均P<0.05)。非器械相关的医院获得性感染中肺部感染占比由23.53%上升至46.00%,差异具有统计学意义(P<0.05)。结论连续三年目标性监测显示,器械相关感染发病率下降,但非器械感染发病率升高。医院感染管理应增加监测非机械通气患者医院感染防控措施的落实情况,从而整体降低ICU医院感染发病率。
