High expression of HVEM is associated with improved prognosis in intrahepatic cholangiocarcinoma

Herpesvirus entry mediator (HVEM) displays dual signals in T-cell activation according to the ligands and intracytoplasmic effectors it interacts with. High HVEM expression may play an immunosuppressive role in several malignancies. The present study investigated the clinical impact of HVEM on intrahepatic cholangiocarcinoma (ICC), including its prognostic value, and association with clinicopathological features and immune status. The clinical data of 102 consecutive patients with ICC who underwent surgical treatment from January 2012 to December 2017 were collected. The expression of HVEM and different types of tumor-infiltrating lymphocytes (TILs) were investigated in ICC tissue samples by immunohistochemical staining. HVEM expression was detected in the tumor tissues of 92 (90.2%) patients with ICC. Patients with high HVEM expression were more likely to have increased peripheral blood lymphocyte (PBL) concentrations (P=0.031), decreased CEA (P=0.036), low TNM stage (P=0.043) and high frequencies of small-duct histological type (P=0.021) and BAP1 retained expression (P=0.010). Survival analysis showed that high HVEM expression was a favorable independent predictor of overall postoperative survival (P=0.034, hazard ratio=0.486, 95% confidence interval=0.249–0.945). In addition, no significant association of HVEM expression with CD4⁺ (P=0.512), CD8⁺ (P=0.750) or CD45RO⁺ (P=0.078) TILs was identified in the ICC tissues. These results indicate that HVEM may serve as a favorable prognostic marker for ICC. Furthermore, co-stimulatory signals from HVEM may play a dominant role in the progression of ICCs, which can be explained by an increase in the number of PBLs rather than a change in the number of TILs. However, the function of the HVEM network in ICC progression is complex and requires further study.     

信息化质量溯源系统在消毒供应中心外来医疗器械管理与预防骨科感染中的应用价值

目的探讨信息化质量溯源系统在消毒供应中心(CSSD)外来医疗器械管理与预防骨科感染中的应用价值。方法随机选取消毒供应中心2018年1月1日至2018年12月31日期间未采用信息化质量溯源系统的500件骨科外来医疗器械作为对照组,随机选取消毒供应中心2019年3月1日至2019年11月期间采用信息化质量溯源系统的500件消毒供应中心骨科外来医疗器械作为观察组,比较两组外来器械管理效果、外来器械管理质量及医院骨科感染率。结果手术前做好再生处理、器械完好程度、外来器械按时送达医院观察组均高于对照组(P<0.05);不及时更换损坏器械、手术后器械丢失、器械磨损度、信息保存不完善、混淆错拿器械包低于对照组(P<0.05);医院骨科感染率观察组为0.00%低于对照组8.00%(P<0.05)。结论信息化质量溯源系统应用于CSSD外来医疗器械管理中通过提高外来器械管理效果和外来器械管理质量,有效降低医院骨科感染率。     

前列地尔结合丹参注射液治疗老年髋部骨折下肢深静脉血栓护理研究

目的:观察老年髋部骨折下肢深静脉血栓(DVT)采用前列地尔结合丹参注射液治疗的临床价值和护理效果。方法:将老年髋部骨折患者84例根据数字表法随机分为对照组和观察组,每组42例。2组实施手术后,对照组给予低分子肝素钠皮下注射,观察组给予前列地尔注射液联合丹参注射液静脉滴注,连续治疗2周。对比2组DVT发生率和48 h伤口引流量、治疗前后髌下10 cm周径、视觉模拟评分法(VAS)评分、血小板、活化部分凝血酶原时间(APTT)、D-二聚体(D-D)的差异。结果:观察组DVT发生率较对照组低,48 h伤口引流量较对照组少,差异有统计学意义(P0.05)。2组治疗前髌下10 cm周径、VAS评分比较,差异无统计学意义(P0.05)。2组治疗后髌下10 cm周径、VAS评分均改善,观察组治疗后髌下10 cm周径较对照组短,VAS评分较对照组低,差异有统计学意义(P0.05)。2组治疗前血小板、APTT、D-D比较,差异无统计学意义(P0.05)。2组治疗后血小板、APTT、D-D较前改善,观察组治疗后血小板计数较对照组少,APTT较对照组短,D-D较对照组低,差异有统计学意义(P0.05)。结论:老年髋部骨折下肢DVT采用前列地尔和丹参注射液联合治疗,能明显降低下肢DVT发生率,减轻患者疼痛症状。     

医学生人格特质与共情能力的相关性研究

目的  测评医学生的共情能力现状，探讨人格特质对其共情能力的影响,为培养医学生的共情能力提供对策。方法  以上海市3所高校临床医学专业学生为研究对象，采用班级整群抽样的方式进行问卷调研。采用杰斐逊共情量表-医学生版（JSPE-S）和大五人格量表（NEO-FFI）分别评估医学生的共情和人格特质。结果  共发放问卷2 020份，回收有效问卷1 958份，有效率为96.93%。医学生的共情能力总分均值为（103.24±14.35）。共情能力总分与大五人格中的“外向性”“开放性”“宜人性”“严谨性”维度呈显著正相关（r=0.154~0.406, P<0.01），与大五人格中的“神经质”维度呈显著负相关（r=-0.175, P<0.01）。分层回归结果表明：“共情重要性”和“大五人格”量表的5个维度进入回归方程。其中，人格因素占可解释方差变异量的16.2%（P<0.01）。结论  我国医学生的共情能力低于国外医学生，重视人格特质的塑造有助于提高其共情能力。     

Prenatal diagnosis of fetal right ventricular diverticulum with massive pericardial effusion in one of monochorionic diamniotic twins: a case report with a favorable outcome following in utero pericardiocentesis

BackgroundCongenital ventricular diverticulum is a rare abnormality that may occur as an isolated malformation. Most cases are accompanied by pericardial effusion. Prenatal counseling can be difficult because the prognosis is uncertain and there is no consensus approach to prenatal management.Case presentation: We describe a case of congenital cardiac diverticulum complicated by large pericardial effusion in one of monochorionic diamniotic twins. The case was diagnosed by ultrasonography at 21 weeks of gestation. Therapeutic pericardiocentesis at 22 weeks resulted in complete resolution of the effusion and led to a favorable fetal outcome. We summarize the interventions and pregnancy outcomes in cases of cardiac diverticula reported in the literature.ConclusionsBetter awareness of clinical features, in utero therapies, and pregnancy outcomes could help define and improve prenatal management of congenital ventricular diverticula.
