Objective The paper aimed to discuss the influence of case teaching of forensic pathology based on network platform on the critical thinking ability of forensic students．Methods Students majoring in forensic were randomly divided into the experimental group and the control group with 20 students per group. According to heterogeneity classification， the experimental group was divided into 4 subgroups. The subgroups participated in network cases learning whereas the control group received traditional case teaching. Participants were required to fill in California Critical Thinking Disposition Inventory-Chinese Version (CCTDI-CV) before and after learning. CCTDI-CV scores， the scores of final exam and the number of students who had improved in CCTDI-CV scores were compared between the two groups. Results For the experimental group， the total score of CCTDI-CVand the scores of items including looking for the truth， systematized ability， self-confidence， thirst for knowledge were significantly improved after learning. The performance of the experimental group was better than that of the control group at the end of teaching(P<0.05) . The scores of final exam were higher in the experimental group compared to the control group (P<0.05) ．Conclusion Forensic pathology cases teaching based on network platform is an effective way to stimulate students' critical thinking ability and to improve the study ability.

目的人工智能（AI）全涂片自动化硅藻检验技术能比人类专家更快速、高效进行法医病理学溺死硅藻检验。然而，该技术仅与硅藻提取率较低的硝酸消化法联用过，本研究拟采用更加高效的蛋白酶K组织消解法（以下简称酶消化法）作为硅藻提取方法，探究该技术在其他硅藻提取方法中的泛化能力及可行性。方法收集6例溺死尸体的肺组织进行蛋白酶K消解并制成涂片，利用数字化图像矩阵切割方法将涂片进行数字化处理并据此建立硅藻-背景数据库，将数据集按照3：1：1的比例分为训练集、验证集和测试集，在ImageNet预训练基础上对卷积神经网络（CNN）模型进行训练和内部验证及外部测试。结果结果显示最佳模型外部测试的准确率达97.65%，且模型特征提取区域即为硅藻所在区域。实际应用中最佳的CNN模型对溺水尸体的硅藻检测精准率高达80 %以上。结论研究表明，基于CNN模型的AI自动化硅藻检验技术和酶消化法联用能高效识别硅藻，可以作为溺水鉴定中硅藻检测的辅助方法。

【目的】研究大鼠急性心肌缺血后不同时间再灌注心脏不同区域HSP70 和Fos 蛋白表达的规律, 为心肌缺血/再 灌注损伤所致心性猝死的法医学诊断提供形态学依据。【方法】结扎大鼠左冠状动脉前降支建立急性心肌缺血/ 再灌注模型。 用免疫组织化学方法, 观察心肌缺血后不同时间再灌注HSP70 和Fos 蛋白在心肌组织表达的改变。【结果】对照组心肌组织 无Fos 和HSP70 表达。心肌缺血15 min 再灌注0.5 h 后Fos 蛋白即在缺血区域表达, 随着再灌注时间延长表达增强;非缺血 区域1 h 始有表达, 缺血区域表达明显强于非缺血区域。心肌缺血区域再灌注1 h 后HSP70 始有表达, 随着再灌注时间延长 表达增强;非缺血区域心肌2 h 始有表达, 且明显弱于缺血区域。再灌注早期HSP70 和Fos 首先在心肌内层表达, 随着时间延 长表达向心肌外层扩展。【结论】心肌缺血/ 再灌注早期不同时间HSP70 和Fos 蛋白表达有不同的区域性及强度, 有可能为早 期心肌缺血/ 再灌注提供一项新的辅助诊断的形态学指标。

法医病理学实践技能培训是保障法医病理学教学质量、培养合格法医病理学人才的重要环节。通过分析法医病理学实践技能培养的现状及不足，提出改善法医学病理学实践教学水平的建议，即完善教学内容、改进考核方式、重视形成性评价、组建合格的实践教学团队等，有助于实践教学水平的提高。 [ABSTRACT FROM AUTHOR]

Objective: Through the retrospective of the forensic assessment cases of 30 Cases of viral myocarditis, to provide reference for the forensic assessment in those cases. Methods: 30 cases of viral myocarditis' s death from the judicial identification center of Kunming Medical University between January 2003 to July 2014 were retrospected. Results: Most of the 30 cases died of acute cardiac dysfuction due to heavy viral myocarditis and all cause myocardial damage. Myocardial damage mainly includes cardiocyte edema, matrix dissolute and necrosis, many lymphocytes are scattered in the myocardial interstitium, at the same time accompany with different level damage of organs such as lung, brain, amygdala. Conclusion: Severe viral myocarditis is repid onset and atypical clinical symptoms, fast process, incur misdignose and therapeutic error easily, high mortality, so foresic identification is needed. When identificating viral myocarditis in forensic, heart generally and microscopic observed as the main base, but also paying special attention to other mechanical damage, identifing of the relationship between each causes of death, combining with the special inspection when necessary, for example the detection of chemokines MCP- 1.
