集束化干预联合闭环管理对ICU多重耐药菌感染的防控效果

目的 探讨集束化干预策略联合闭环管理模式对ICU多重耐药菌感染的防控效果。方法选取2020年1~12月EICU住院患者275例作为对照组，实施常规管理；2021年1~10月EICU住院患者239例作为观察组，在常规管理基础上实施集束化干预策略联合闭环管理。结果实施后，观察组多重耐药菌感染发生率明显低于对照组；患者住院日显著低于对照组，4项护理措施执行率(隔离标识、手卫生、环境消毒、医务人员相关知识知晓)、病原学送检率显著高于对照组（均P<0.05）。结论集束化干预联合信息化闭环管理可有效降低EICU多重耐药菌感染发生率。

子野个数限值对宫颈癌固定野调强放疗计划的影响

目的:分析子野个数限值对宫颈癌固定野调强放疗（fixed-field intensity-modulated radiotherapy,ff-IMRT）计划的影响，寻求最优的子野个数限值。方法:选取10例接受ff-IMRT的宫颈癌患者，基于Monaco 5.11.03计划系统，以45 Gy/25 f处方剂量分别对同一患者设计8种ff-IMRT计划（ff-IMRT计划依据子野个数限值命名，子野个数限值分别为40、60、70、80、100、120、130、150），采用SPSS 20.0软件比较除plan100之外7个ff-IMRT计划与plan100剂量学参数、优化时间和治疗参数的差异。结果:8种ff-IMRT计划归一化后，plan40和plan60的D2%、Dmin、CI和HI均劣于plan100（P＜0.05）。8种ff-IMRT计划均能较好保护危及器官（organ at risk,OAR）和正常组织。plan40小肠V45;plan40和plan60小肠D2cc，直肠、膀胱V45、D40%，两侧股骨头V40和正常组织 V35、V40均高于plan100（P＜0.05）。plan40和plan60优化时间、治疗参数均优于plan100（P＜0.05）；plan120、plan130和plan150子野面积、子野个数（51~150 cm2和＞150 cm2）和出束时间均劣于plan100（P＜0.05）。结论:子野个数限值为70~100时，ff-IMRT计划能兼顾剂量学参数满足临床要求、优化时间和治疗参数最优化，建议在设计宫颈癌ff-IMRT计划时在该范围内设置子野个数限值。     

Confounded association between proton pump inhibitor use and risk of biliary tract cancer: Result from three cohorts

Recent epidemiological studies suggested that proton pump inhibitor (PPI) use was associated with an increased risk of biliary tract cancer (BTC), however, confounders were not adequately controlled. Our study aimed to evaluate PPI use and subsequent risk of BTC and its subtypes in three well-established cohorts. We conducted a pooled analysis of the subjects free of cancers in UK Biobank (n = 463 643), Nurses' Health Study (NHS, n = 80 235) and NHS II (n = 95 869). Propensity score weighted Cox models were used to estimate marginal HRs of PPIs use on BTC risk, accounting for potential confounders. We documented 284 BTC cases in UK Biobank (median follow-up: 7.6 years), and 91 cases in NHS and NHS II cohorts (median follow-up: 15.8 years). In UK biobank, PPI users had a 96% higher risk of BTC compared to nonusers in crude model (HR 1.96, 95% CI 1.44-2.66), but the effect was attenuated to null after adjusting for potential confounders (HR 0.95, 95% CI 0.60-1.49). PPI use was not associated with risk of BTC in the pooled analysis of three cohorts (HR 0.93, 95% CI 0.60-1.43). We also observed no associations between PPI use with risk of intrahepatic (HR 1.00, 95% CI 0.49-2.04), extrahepatic bile duct (HR 1.09, 95% CI 0.52-2.27) and gallbladder cancers (HR 0.66, 95% CI 0.26-1.66) in UK Biobank. In summary, regular use of PPIs was not associated with the risk of BTC and its subtypes.     

乙肝肝硬化患者门静脉血栓形成的相关因素分析

目的 分析乙肝肝硬化患者门静脉血栓(PVT)形成的影响因素.方法 选取2018年7月至2021年6月新乡市传染病医院肝病科350例乙肝肝硬化患者作为研究对象,统计所有患者PVT形成情况,由研究者设计基线资料调查问卷,询问并记录患者基线资料,检测研究所需的实验室指标并比较,将可能的影响因素纳入,经logistic回归分析检验,找出乙肝肝硬化患者PVT形成的影响因素.结果 350例乙肝肝硬化患者中PVT形成31例,发生率为8.86％(31/350);发生组合并糖尿病占比高于未发生组,发生组门静脉血流速度、白蛋白(ALB)水平比未发生组低,发生组血小板计数(PLT)比未发生组高,差异有统计学意义(P<0.05);logistic回归分析检验结果显示,合并糖尿病、PLT水平高是乙肝肝硬化患者PVT形成的危险因素(OR>1,P<0.05);门静脉血流速度快、ALB水平高是其保护因素(OR<1,P<0.05).结论 乙肝肝硬化患者PVT形成的影响因素可能为合并糖尿病、PLT水平高、门静脉血流速度快、ALB水平高.
