以专培学员为主导的CBL教学对心血管专培学员自身综合能力提升的影响

心血管专科医师规范化培训目标要求高于住院医师培训，完成心血管专培的医生应能在医疗、教学、科研能力上明显提高，达到心血管专科主治医师水平。如何提高心血管专培学员教学能力是专培中的难点。将专培学员随机分为两组,分别采用案例教学法（case-based learning, CBL）和传统教学法进行带教,课程结束后通过测验和调查问卷两种方式对教学效果进行考察。旨在探讨由心血管专培学员主导CBL教学法在实施过程中是否对其自身综合能力有所提升。结果显示，CBL教学法组学生临床理论及病例分析考试分数均高于对照组；心血管专培学员通过主导CBL教学，在教学能力、组织能力和学科协调均有提升；相较传统教学法,CBL教学法的教学效果更佳,有利于心血管专培学员自身综合能力提升。

腹腔镜肝癌根治术的热点与未来发展

随着腹腔镜肝切除技术的发展与推广，腹腔镜肝切除中的一些难点，如术中出血的控制、解剖性肝切除、巨大肝癌切除、腹腔镜下联合肝脏分割与门静脉支结扎的二步肝切除术(ALPPS)等方面均基本解决。术中超声与荧光染色技术也得到普及。本文就上述问题做一概述，并对腹腔镜肝切除未来发展提出思路，以进一步推动我国腹腔镜肝切除的技术进步。     

Three-dimensional measurement of radiographic bone–implant contact lengths of zygomatic implants in zygomatic bone: a retrospective study of 66 implants in 28 patients

Zygomatic implant treatment is widely applied for severe maxillary atrophy to help rehabilitate the maxillary dentition. This retrospective study was performed to evaluate the actual radiographic bone–implant contact (rBIC) lengths of zygomatic implants. The records of 28 patients who underwent zygomatic implant surgery and subsequent follow-up examinations between August 2013 and September 2018 in the Department of Oral and Maxillofacial Surgery, Taipei Tzu Chi Hospital were reviewed. The surgeries were performed by a single surgeon using the same treatment protocol. All patients had a computed tomography scan at 1 year after the surgery. Using three-dimensional imaging software, an investigator measured the rBIC lengths of 66 implants and documented their clinical status. The implant survival rate was 100%. The mean rBIC length was significantly longer in male patients than in female patients (20.80 ± 5.88 mm versus 17.79 ± 6.34 mm; P = 0.028). The mean rBIC length of double zygomatic implants was significantly longer when compared to that of single implants (21.11 ± 6.23 mm versus 17.75 ± 5.85 mm; P = 0.027). This article is novel in reporting the exact rBIC lengths of zygomatic implants in a clinical setting. The results showed that zygomatic implants are a viable treatment modality for full-mouth rehabilitation.     

Review of clinical characteristics,immune responses and regulatory mechanisms of hepatitis E-associated liver failure

Hepatitis E virus (HEV) is the most common cause of acute liver failure (LF) and one of the most common factors causing acute injury in acute-on-chronic LF (ACLF). When HEV-related LF occurs, a series of changes take place in both the intrahepatic environment and extrahepatic microenvironment. The changed types and distribution of immune cells (infiltrating macrophages and increased lymphocytes) in liver tissue, as well the increased proinflammatory cytokines and chemokines in the blood, indicate that the occurrence and progression of HEV-related LF are closely related to immune imbalance. The clinical features and immune reaction in the body during HEV-related acute LF (ALF) and ACLF are complicated. This review highlights recent progress in elucidating the clinical manifestations of HEV-associated ALF and ACLF and discusses the corresponding systemic immune changes and possible regulatory mechanisms.
