舒心益脉胶囊对冠状动脉病变的影响及临床观察

目的：观察舒心益脉胶囊对冠状动脉病变的影响及临床疗效。方法：86例冠病患，随机分为舒心益脉胶囊组（治疗组）46例，地奥心血录组（对照组）40例，平均治疗14个月后重复冠状动脉造影，采用计算机定量测定系统评价冠状动脉病变狭窄程度的变化，同时随访患听临床情况。结果：治疗组用药后冠状动脉病变的进展、再狭窄及不稳定性心绞痛的发生率均明显低于对照组（P＜0．05），而病变的减轻、稳定有病情的稳定均明显于对照组（P＜0．05）。治疗组、对照组总有效率分别为84．5％、60．0％（P＜0．05）。结论：长期服用舒心益脉胶囊显降低冠状动脉病变进展，并显减少心脏事件和不稳定性心绞痛发生，明显改善临床症状。     

冠心病猝死心肌肌红蛋白缺失的免疫组化研究

作者应用免疫组化ABC法首次对SCD及对照组病例的心肌Mb缺失情况进行了研究,并经扫描显微镜光度计测量及电子计算机统计分析,结果发现SCD组心肌Mb均有明显缺失,呈现多发、散在、节段性分布,而对照组无缺失,认为这种多发、散在、节段性Mb缺失可作为无大片心肌梗死的SCD病例的诊断标志之一,为SCD的尸检诊断开辟了新途径。     

微生态制剂—XA1503菌粉的研制和应用

Cytoskeleton immunohistochemical study of early ischemic myocardium

Previous studies on cytoskeletal changes of in vitro and in vivo animal models of ischemic myocardium have suggested the possibility of using alterations in cytoskeleton proteins as an early marker for the post-mortem diagnosis of myocardial ischemia in cases of sudden death due to coronary artery disease (CAD). In the present study, using the technique of ABC-immunohistochemistry, we examine the changes of three cytoskeletal proteins: vinculin, desmin and α-actinin in human myocardial samples taken from 14 cases of CAD sudden death and 13 cases of non-CAD death. Results of these examinations are compared with immunohistochemical changes of myoglobin and histochemical staining of hematoxylin and eosin and phosphotungstic acid, and Masson trichrome. Patchy and extensive loss of the three cytoskeletal proteins was demonstrated in the myocardium of victims who died 1 h or later following the onset of symptoms of ischemic myocardium. The pattern of cytoskeleton change is equivocal in the cases of CAD who died less than 1 h after the onset of symptoms and of the cases of non-CAD. In these cases, no significant histological change was observed. With less non-specific background changes and stronger positive staining, immunohistochemical staining of the three cytoskeletal proteins is more reliable than myoglobin, which has attracted the attention of many pathologists searching for anatomic evidence of ischemic myocardium in coronary artery disease.

社会转型与农村医疗卫生

随着我国进入社会转型加速期,农村医疗卫生的宏观环境发生了重大变化,农民对健康越来越重视,健康观念对农民生活的影响也越来越大.农村疾病模式也正向慢性病模式转变,农民面临双重疾病负担.农民求医难、看病贵问题仍然没有得到很好解决,新农村建设中必须大力加强农村医疗卫生建设.     

A retrospective analysis of cardiovascular deaths: A 5-year autopsy study of 1045 cases in Antalya,Turkey

This study aims to identify the macroscopic and microscopic changes that occur in the heart in different causes of cardiovascular death and sudden cardiac death in autopsy cases and evaluate the difficulties that a forensic practitioner may encounter during autopsies. All forensic autopsy cases in the Morgue Department of the Council of Forensic Medicine, Antalya Group Administration between January 1, 2015, and December 31, 2019, were examined, retrospectively. The cases were chosen according to inclusion and exclusion criteria, and their autopsy reports were examined in detail. It was determined that 1045 cases met the study criteria, 735 of which were also met the sudden cardiac death criteria. The top three common causes of death were ischemic heart disease (n = 719, 68.8%), left ventricular hypertrophy (n = 105, 10%), and aortic dissection (n = 58, 5.5%). The frequency of myocardial interstitial fibrosis was significantly higher in deaths due to left ventricular hypertrophy than in deaths due to ischemic heart disease and other causes (χ²(2) = 33.365, p < 0.001). Despite detailed autopsy and histopathological examinations, some heart diseases that cause sudden death may still not be detected.     

The mouse that trolled: the long and tortuous history of a gene mutation patent that became an expensive impediment to Alzheimer's research

This case study presents the tale of the academic discovery of a rare mutation for early-onset Alzheimer''s disease that was patented by a sole inventor and licensed to a non-practicing entity (NPE), the Alzheimer''s Institute of America (AIA). Our aims are (1) to relate this story about patents, research tools, and impediments to medical progress, and (2) to inform ongoing debates about how patents affect research, disposition of university inventions, and the distribution of benefits from publicly funded research. We present an account of the hunt for Alzheimer''s genes, their patenting, assignment, and enforcement based on literature, litigation records and judicial decisions. While AIA''s litigation eventually failed, its suits against 18 defendants, including one university, one foundation, and three non-profit organizations were costly in court years, legal fees, and expert time. Reasons for the failure included non-disclosure of co-inventors, State laws on ownership and assignment of university inventions, and enablement. We discuss the policy implications of the litigation, questioning the value of patents in the research ecosystem and the role of NPEs (“patent trolls”) in biotechnological innovation. The case illustrates tactics that may be deployed against NPEs, including, avenues to invalidate patent claims, Authorization and Consent, legislative reforms specifically targeting NPEs, reforms in the America Invents Act, and judicial action and rules for judicial proceedings. In the highly competitive research environment of Alzheimer''s genetics in the 1990s, patents played a minor, subordinate role in spurring innovation. The case produces a mixed message about the patent system. It illustrates many mistakes in how patents were obtained, administered, and enforced, but, eventually, the legal system rectified these mistakes, albeit slowly, laboriously, and at great cost.     

Susan Sontag,battle language and the Hong Kong SARS outbreak of 2003

Abstract

The widespread use of military language to describe modern epidemics is often attributed to the popularization of the germ theory of disease. Whatever its origins, critics regularly deplore martial imagery in the medical context finding it by turns dangerous, humiliating, and offensive. This article examines the most famous of these critiques, Susan Sontag's rebuttal of disease-as-war language, and finds it problematic in a number of respects. Mass emergency response to the Severe Acute Respiratory Syndrome (SARS) outbreak in Hong Kong in 2003 offers a cross-cultural case study in the use of representations of war. Key to the argument is the proposition that disease-as-war language expresses something ‘real’ not illusory, vital not frivolous, about the community which employs it. The language is a vehicle for articulating social emotions of collective fear, patriotism, homage, and exculpation in conditions that presage collective death
