p53 and BLC2 Immunohistochemical Expression Across Molecular Subtypes in 1099 Early Breast Cancer Patients With Long-Term Follow-up: An Observational Study

Introductionp53 and antiapoptotic B-cell leukemia/lymphoma 2 (BLC2) have been proposed as prognostic markers for early breast cancer (BC), although their relationship with conventional parameters and patient prognosis, as well as their distribution within the molecular BC subtypes remains uncertain.Patients and MethodsIn this observational study, we analyzed the immunohistochemical expression of p53 and BLC2 in 1099 early BC patients surgically treated between 2000 and 2006 and followed for at least 5 years, also considering their association with pathologic factors and molecular subtypes, as well as their influence on disease-free survival.Resultsp53 and BLC2 are distributed differently across molecular subtypes (P < .0001); in particular, p53 positivity and BLC2 negativity seems to be associated with more aggressive conventional tumor phenotypes. Moreover, BLC2 negativity seems to be a significant discriminating factor for disease-free survival (P = .003) according to Kaplan-Meier analysis, while p53 seems to have no discriminating effect. Among patients with discordant p53/BLC2 phenotype, the combination p53⁺BLC2⁻ seems to be associated with the worst outcomes (P = .007) and significantly influenced the clinical course of node-negative patients treated only with hormone therapy (P = .004).ConclusionThese two biomarkers, in addition to conventional pathologic factors and molecular subtype, could help define the risk and outcome of BC.     

Japanese version of The Cancer Genome Atlas,JCGA, established using fresh frozen tumors obtained from 5143 cancer patients

This study aimed to establish the Japanese Cancer Genome Atlas (JCGA) using data from fresh frozen tumor tissues obtained from 5143 Japanese cancer patients, including those with colorectal cancer (31.6%), lung cancer (16.5%), gastric cancer (10.8%) and other cancers (41.1%). The results are part of a single‐center study called “High‐tech Omics‐based Patient Evaluation” or “Project HOPE” conducted at the Shizuoka Cancer Center, Japan. All DNA samples and most RNA samples were analyzed using whole‐exome sequencing, cancer gene panel sequencing, fusion gene panel sequencing and microarray gene expression profiling, and the results were annotated using an analysis pipeline termed “Shizuoka Multi‐omics Analysis Protocol” developed in‐house. Somatic driver alterations were identified in 72.2% of samples in 362 genes (average, 2.3 driver events per sample). Actionable information on drugs that is applicable in the current clinical setting was associated with 11.3% of samples. When including those drugs that are used for investigative purposes, actionable information was assigned to 55.0% of samples. Germline analysis revealed pathogenic mutations in hereditary cancer genes in 9.2% of samples, among which 12.2% were confirmed as pathogenic mutations by confirmatory test. Pathogenic mutations associated with non–cancerous hereditary diseases were detected in 0.4% of samples. Tumor mutation burden (TMB) analysis revealed 5.4% of samples as having the hypermutator phenotype (TMB ≥ 20). Clonal hematopoiesis was observed in 8.4% of samples. Thus, the JCGA dataset and the analytical procedures constitute a fundamental resource for genomic medicine for Japanese cancer patients.     

呼吸内科PBL教学法在全科医师规培中的应用

目的探索基于呼吸治疗团队教学的以问题为基础的教学法(problem based learning,PBL)在全科住院医师规范化培训中的应用。方法呼吸系统以老年人慢性疾病为主,是全科医学生教育的重要环节。开展PBL教学法的教学探索,以期达到对全科医师的专科疾病培训,使其理解并掌握相关疾病知识,能适应未来医学发展和社会需要,为患者提供更好的社区医疗服务。结果PBL教学法的精髓是发挥问题对学习过程的指导作用,调动学生学习的积极性和主动性,整体提升学生的综合素质和能力。结论在全科医学规范化培训教学中运用PBL教学,带教老师以任务为主线、以学员为主体进行引导,可极大的提高学生的学习兴趣、主动性以及自学能力,从而培养学员的分析问题、解决问题的能力。可以更好的帮助学员形成以患者为中心的临床诊断思路、提高解决临床问题的综合能力及团队合作能力。     

《中医基础理论》多元化教学评价方式的构建与实践

《中医基础理论》是中医学课程体系中的主干课程,其教学质量对于中医学人才的总体培养质量具有举足轻重的作用。构建科学合理的教学评价方式是切实推进教学改革,提升教学质量的重要一环。文章论述了《中医基础理论》课程多元化教学评价方式的构建和具体实施方案,在整个《中基》教学过程的不同阶段合理地运用三种评价方式,进行全面客观和准确的判断评价,从而为师生"教"与"学"的切实改进和提升提供真实的依据。实践表明:多元化教学评价方式增强了学生学习的兴趣,提高了学生自主学习的积极性和能力,提高了学生运用知识分析和解决问题的能力,培育了学生的团队协作精神和创新思维;同时,激发了教师教学的热情,促进了教师教学理念、教学方法、教学手段以及专业知识的更新,提高了教师综合素质。本文对实践中存在的问题也进行了总结。     

中药配方颗粒品种统一标准的有关问题探讨

通过参考《中国药典》2015年版和相关文献,结合国家药典委员会2016年发布的《中药配方颗粒质量控制与标准制定技术要求(征求意见稿)》,综合考虑中药配方颗粒的实际生产情况,对《关于中药配方颗粒品种试点统一标准的公示》中质量标准特异性、定量检测指标的选择和指标性成分转移率等方面进行讨论,根据讨论结果为中药配方颗粒质量标准的完善和提高提出了相关建议,为推进配方颗粒产业健康发展提供参考。     

中西医不同角度对儿童新型冠状病毒肺炎(COVID-19)的认识

2019年12月以来,以湖北省武汉市为中心陆续发现了多例新型冠状病毒肺炎(COVID-19)患者。人群普遍易感,儿童亦有感染病例出现,感染波及新生儿、婴幼儿,并且已出现儿童重症病例。儿童感染病例引起了社会高度重视。目前COVID-19病理机制尚不清楚,治疗亦缺乏特效药,这些问题都给疫情防控和临床救治带来极大困难。尝试从中西医不同角度认识儿童COVID-19,分析儿童COVID-19病因、流行特点、病情发展特点及治疗措施,同时从中医角度探讨儿童COVID-19病因病机、辨证及治疗方法,能更好地通过中西医结合对此次儿童COVID-19进行深入了解,理解其病理之基础,分析目前疫情发展之趋势,并在此基础上寻找安全有效的防治措施,以期对临床更好地防治儿童COVID-19提供参考。
