急性缺氧对飞行员胃液排空功能的影响

为探讨急性缺氧对飞行人员胃液体排空功能的影响，在常压下吸入不同浓度氧（17％、16％、14％、12％、10．5％及9％）的低氧混合气体30min，采用B型超声波在实验前后分别测量了64名男性飞行员的胃液体排空功能。结果表明，吸入17％低氧混合气胃排空延迟，但经统计学处理无显著性差异（P＞0．05），吸入16％以下的低氧混合气后胃排空延迟，经统计学处理有显著性差异（P＜O．01），且随着缺氧程度加重，胃液体排空时间延长更加明显。提示当发生高空缺氧时，应考虑到缺氧对胃排空有抑制作用这一因素。

重症急性胰腺炎早期非手术治疗的探讨

目的：探讨重症急性胰腺炎（SAP）的治疗效果。方法：采取回顾性总结方法对1992年1月～1997年5月收治的86例SAP病例资料，分析发病2周内非手术治疗和手术治疗的并发症发生率以及治愈率。结果：发现经早期非手术治疗使SAP特别是SAPⅡ型的病人并发症发生率大大降低，并提高了疾病的治愈率。结论：在ICU的严密监护下，对SAP患者采用全身支持治疗，使用抗胰酶制剂，胰腺休息治疗，以及预防性应用抗生素等早期非手术治疗取得明显的效果，值得提倡和推广。     

急性病毒性肝炎住院患者血清学分型与流行病学分布研究

本文收集了西安市住院急性病毒性肝炎患者血清标本２９３份，用ＥＬＩＳＡ进行分型检测，并作流行病学调查。结果发现：甲肝占６５．１９％，乙肝占１０．９２％，丙肝占４．７８％，丁肝占３．７５％，戊肝占４．４４％，诊断不明者占１０．９２％。结果表明，在西安市住院的急性病毒性肝炎中，甲肝为主要类型；与以往结果比较，甲肝患者的发病年龄明显后移；除乙肝外，各型肝炎中男性均多于女性，尤以丁肝和戊肝为著；甲肝有明显的     

乳腺癌的X线诊断（附186例分析）

本文搜集经手术病理证实的186例乳腺癌，分析了乳癌的发病年龄与乳腺类型的关系，讨论了乳癌的各种X线表现，着重探讨了乳腺癌几种病理类别的X线表现特点，作者将乳腺癌的X线表现归纳为四型：肿块型（又分为团块形，结节形和不规则形），浸润型，钙化型和结构紊乱型，联系其病理结构，提出诊断要点以提高诊断。     

高血压病患者左心室舒张功能新指标测定

目的观察左心室舒张功能新指标测定的意义。方法应用脉冲多普勒技术测定高血压病Ⅰ期（20例）、高血压病伴左心室肥厚（22例）、高血压病伴有房颤（14例）及25例正常人二尖瓣口及瓣下1cm、2cm、3cm左心室内不同部位的舒张早期充盈速度（E0、E1、E2、E3），计算E1／E0、E2／E0、E3／E0比值。结果高血压病人E3显著降低，E3／E0与自身E2／E0相比有显著差异（P＜0．01），且E3／E0与常规测定舒张功能指标E／A法有良好的相关性。高血压病Ⅱ组与高血压病Ⅰ组相比，舒张功能障碍更为明显。结论高血压病早期即有左心室舒张功能减退，并出现于心室功能障碍之前，且左心室舒张功能减退随心肌受损加重而明显。E3／E0法是反映左心室舒张功能障碍的良好指标，可弥补E／A法的不足。     

Outbreaks of smallpox due to variolation in China, 1962-1965

In 1985, previously unknown outbreaks of smallpox were uncovered which had occurred in Shanxi Province and Nei Monggol Autonomous Region in northern China during 1962-1965, several years after smallpox transmission was thought to have been interrupted. During field investigation, the authors learned that most of the cases were known to local health officials but had not been officially reported to national authorities. All were among persons who had been variolated or were their close contacts. Variolation is an ancient method of protection against naturally acquired smallpox that was officially proscribed in the early 1950s but was renewed in remote areas when smallpox vaccination activities were interrupted during the three-year famine of 1959-1962, following the "great leap forward" program of 1958. It was found that the variolators in Shanxi Province and Nei Monggol Autonomous Region inoculated persons with the use of powdered smallpox scabs mixed with human milk, and that they obtained fresh supplies of scabs every 6-12 months by variolating relatives and friends. The health authorities responded by capturing the variolators, confiscating their variolation material and equipment, and vaccinating the population. The last known cases occurred in 1965, and the practice of variolation is now believed to be extinct.
