新冠疫情背景下组织学与胚胎学网络教学的实施及教学反思*

2020年1月,突发的新冠肺炎疫情给我国经济社会发展带来巨大的挑战,能否将信息技术和网络教学完美融合,确保网络教学的质量,是摆在每一位教育工作者面前的问题[1].按照国家关于新型冠状病毒肺炎疫情防控工作部署要求,遵循"停课不停教、停课不停学"的原则,在2020年春季学期面向本校中医学、针灸推拿学、临床医学等专业开设组织学与胚胎学课程的网络教学.组织学与胚胎学是医学院校中非常重要的专业基础课,与现代医学及生命科学相互交叉与渗透,该学科研究的是正常人体的微观结构及功能,具有教学内容多、知识点繁杂、专业术语多、教学学时偏少、学生学习难度较高等特点[2].

胃肠超声造影的临床应用价值

目的对比胃肠超声造影的优缺点,探讨对胃十二指肠良恶性病变的诊断符合率,评估胃肠超声造影的临床应用价值。方法选取200例有胃肠道症状患者的胃肠超声造影检查结果,与胃镜检查结果对比分析。结果胃肠超声造影对胃肠道疾病的诊断符合率为94.34%,特异度为100%,敏感度为94.12%,与胃镜对比,在胃十二指肠良恶性病变的检出率的差异无统计学意义(P>0.05)。结论口服胃肠超声造影剂对胃十二指肠结构性病变的诊断符合率高,且能有助于提高胰腺等腹膜后病变的检出率,有较好的诊断价值。应熟练掌握胃肠超声检查的适应证,规范扫查流程。     

双长效支气管扩张剂在慢性阻塞性肺疾病治疗中的研究进展

长效支气管扩张剂是稳定期慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)治疗的基石。固定剂量长效β2受体激动剂(long actingβ2 agonist,LABA)/长效抗胆碱能药物(long acting muscarinic antagonist,LAMA)复方制剂被慢性阻塞性肺疾病全球倡议推荐用于COPD的治疗。为了更深入了解已经上市的多种LABA/LAMA复方制剂如维兰特罗/乌美溴铵、茚达特罗/格隆溴铵、福莫特罗/格隆溴铵及奥达特罗/噻拖溴铵等的疗效和安全性,本文对LABA/LAMA一些重要临床研究作一综述,旨在为COPD患者提供个体化的治疗方案。

Aesthetic outcome of intralesional injection of lauromacrogol as a single-agent treatment for uncomplicated infantile hemangiomas: A long-term follow-up study

Infantile hemangiomas (IH) are at risk of incomplete regression with remnant permanent sequelae, ranging from passive waiting for spontaneous regression to active systemic administration. The application of traditional therapy involving injection of a sclerosing agent is limited due to the difficulty in achieving cosmetic improvement. This study aimed to explore a new injection method that could not only promote tumor regression but also achieve cosmetic improvement. A total of 122 IH (from 109 children) injected intralesionally with lauromacrogol in the Plastic Surgery Department of Fujian Medical University Union Hospital between 1 January 2012 and 1 June 2019 were enrolled in this study. The mean follow-up time was 2.9 years. Of 122 lesions studied, 111 (91.0%) achieved complete regression, 10 (8.2%) achieved significant regression and one (0.8%) achieved moderate regression. In terms of aesthetic appearance, 70 (57.4%) IH had no sequelae and the A score was 5/5. Twenty-one (17.2%) IH had minimal hyperpigmentation, hypopigmentation or telangiectasia and the A score was 4/5. Thirty-one (25.4%) IH had left mild or relatively obvious sequelae and the A score was 1–3/5. None of the 122 IH involved had rebound growth after terminating the treatment. Hyper- or hypopigmentation gradually faded over time and part of the IH had already returned to normal appearance by the time of long-term follow up. The results indicated that this new type of injection therapy significantly promoted the regression of uncomplicated IH and helped achieve the expected cosmetic appearance.     

新型冠状病毒肺炎的中西医防治研究进展

新型冠状病毒肺炎(简称新冠肺炎)归属中医"疫病",主要病位在肺,主要病机为"湿、毒",治疗上解毒化湿贯穿始终。新冠肺炎的主要诊断方法为核酸检测,《新型冠状病毒肺炎诊疗方案(试行第七版)》新增加了血清学检测。中医药在新冠肺炎的预防方面具有很大优势,如中医预防方、香囊、针灸、中国传统功法、食疗、足浴、熏蒸等。在新冠肺炎的治疗过程中,中西医结合疗法效果明显,在缓解患者早期临床症状,减少患者轻症向重症、重症向危重症转化的发生率方面具有重要价值。目前尚无治疗新冠肺炎的特效药,对新冠肺炎的认识尚不完整,因此,文章从新冠肺炎的诊断、预防和治疗3个角度出发,探讨了对新冠肺炎中西医方面的认识,为进一步明确新冠肺炎的诊疗提供参考。     

乳腺专用伽马显像中99Tcm-甲氧基异丁基异腈的摄取与乳腺浸润性导管癌患者临床病理特征的关系

目的分析乳腺浸润性导管癌患者的临床病理特征与乳腺专用伽玛显像(BSGI)中⁹⁹Tc^m-甲氧基异丁基异腈(MIBI)摄取之间的关系。 方法回顾性分析2014年3月至2018年3月就诊于威海市立医院行BSGI检查、未接受新辅助治疗及穿刺活组织检查及术前无肿瘤远处转移的浸润性导管癌患者244例的临床资料。分析患者的BSGI数据，计算病灶的放射性计数与正常组织的比值(T/N)，从而评估肿瘤对⁹⁹Tc^m-MIBI的摄取量。T/N为偏态分布数据，用M(P₂₅～P₇₅)表示。用Wilcoxon秩和检验分析患者临床病理特征与T/N之间的关系，用多元线性回归模型分析患者临床病理特征对T/N的影响。 结果全部244例患者BSGI中的T/N范围为1.0～7.5。Wilcoxon秩和检验结果显示T/N与T分期、N分期、组织学分级及Ki67表达有关(Z＝－6.852、5.198、－3.931，P均<0.001；Z＝－3.059, P＝0.002)，而与ER、PR、HER-2、P53、EGFR表达及三阴性乳腺癌无关(Z＝ －0.730、－1.526、－1.137、－1.175、－1.224、－1.556, P均>0.050)。多元线性回归分析表明T分期及N分期是T/N的影响因素(t＝5.100, 95%CI：0.414～0.935, P<0.001；t＝ 2.819, 95%CI：0.118～0.668, P＝0.005)。 结论乳腺浸润性导管癌的T分期和N分期可能影响BSGI中肿瘤对⁹⁹Tc^m-MIBI的摄取，因此，可以通过术前测定BSGI的T/N，对肿瘤的恶性程度进行初步评估。
