1401例超长住院日患者分布与影响因素分析

目的分析超长住院患者分布及影响因素,探讨减少超长住院日的措施。方法从江苏省某三甲医院病案管理系统中调取2020年1月1日-2020年12月31日134016例出院患者的住院病案首页资料,对住院时间≥30天的1401例超长住院患者的分布特征进行统计描述,采用Logistic回归模型分析超长住院日的影响因素。结果2020年全院平均住院日为7.13天,其中超长住院患者平均住院日为41.85天。超长住院患者以60岁以上年龄组最多(39.61%);出院科室主要分布在血液科(42.18%)、普通外科(11.85%)、骨科(7.49%)等;疾病类别主要为肿瘤(47.32%)、影响健康状态和与保健机构接触的因素(10.56%)、循环系统疾病(7.07%)等;多因素Logistic回归结果显示,男性(OR=1.188)、离院方式为非医嘱离院或其他(OR=2.046)和死亡病例(OR=3.362)是超长住院的危险因素。结论控制超长住院日对平均住院日影响显著,医院应加强重点人群、重点科室和重点病种管理提高诊疗管理水平,缩短平均住院日。     

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。     

腹腔镜与开腹手术治疗长径5~10 cm中危原发性胃间质瘤的安全性和有效性比较

目的　比较腹腔镜和开腹手术治疗长径5~10 cm的中危胃间质瘤的安全性和有效性，并评估患者术后使用伊马替尼辅助治疗是否有明显益处。方法　回顾性分析2010年1月—2020年7月在南京大学医学院附属鼓楼医院接受手术治疗的72例长径在5~10 cm的中危胃间质瘤患者资料。其中腹腔镜手术组28例，开腹手术组44例。比较两组患者基本资料、病理特征、围手术期结果、住院总费用。对比术后使用和不使用伊马替尼辅助治疗的生存率。结果　开腹组和腹腔镜组临床病理特征差异无统计学意义（P>0.05）。腹腔镜组术后并发症发生率为32.1%（9/28），开腹组为52.3%（23/44），两组比较差异无统计学意义（P=0.094）。与开腹组相比，腹腔镜组总住院时间明显缩短［（12.5±3.2） d比（15.0±3.5） d，P=0.004］；术后中位住院天数明显缩短（7.5 d 比 9.0 d，P=0.006）；首次排气时间明显缩短（P=0.003）。中位随访时间58个月（13~129个月），期间未出现与肿瘤相关的死亡病例。开腹组有2例死亡，分别因乳腺癌和心脏病；腹腔镜组有1例死亡，死亡原因与胃间质瘤无关。72例患者中，40例术后接受伊马替尼辅助治疗，开腹组22例（50.0%），腹腔镜组18例（64.3%），两组接受伊马替尼辅助治疗的患者例数占比差异无统计学意义（χ2=1.414，P=0.234）。术后使用伊马替尼辅助治疗组总体生存率与未使用伊马替尼辅助治疗组相比差异有统计学意义 （P=0.015）。结论　与开腹手术相比，腹腔镜治疗长径在5~10 cm的中危胃间质瘤是一种安全有效的方法。实现R0切除的长径在5~10 cm的中危胃间质瘤患者术后使用伊马替尼辅助治疗未增加生存率，且未使用伊马替尼者未出现与肿瘤相关的死亡、复发及转移。     

以宫腔积液为首发症状的胃型宫颈腺癌1例报道并文献复习

宫腔积液指宫腔内液体积存(积水、积血或积脓),是绝经后女性常见体征之一,常于超声检查时发现。持续宫腔积液患者,需宫腔镜检查寻找病因。本文报道1例以宫腔积液为首发症状,经宫腔镜检查确诊为胃型宫颈腺癌的患者。通过病例回顾并文献复习,以期为更多绝经后宫腔积液及宫颈病变的诊断提供参考,避免漏诊及误诊。1病例资料患者67岁,女,主因"绝经18年,不规则阴道出血2月"于2020年5月就诊于首都医科大学附属北京妇产医院妇科微创中心。     

Exploring the potential of exosomes in diagnosis and drug delivery for pancreatic ductal adenocarcinoma

Pancreatic cancer (PC) is a cancer of the digestive system, and pancreatic ductal adenocarcinoma (PDAC) accounts for approximately 90% of all PC cases. Exosomes derived from PDAC (PDAC-exosomes) promote PDAC development and metastasis. Exosomes are nanoscale vesicles secreted by most cells, which can carry biologically active molecules and mediate communication and cargo transportation among cells. Recent studies have focused on transforming exosomes into good drug delivery systems (DDSs) to improve the clinical treatment of PDAC. This review considers PDAC as the main research object to introduce the role of PDAC-exosomes in PDAC development and metastasis. This review focuses on the following two themes: (a) the great potential of PDAC-exosomes as new diagnostic markers for PDAC, and (b) the transformation of exosomes into potential DDSs.     

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.
