论我国医患冲突成因及和谐关系构建

目前我国医患之间的矛盾与冲突，实质上是新时期我国社会矛盾在卫生工作中的具体表现，反映了社会群体在经济状况、价值取向、角色意识、道德水平、法律法规等多方面的矛盾与冲突。和谐医患关系应是构建我国和谐社会的内容之一。和谐医患关系的构建需要完善的社会医疗保障体系建立、国家卫生行政管理加大、财政补偿合理投入、医疗服务质量提高、医学知识教育普及与提高、媒体理性传播、社会大众道德控制水平提升，法律法规完善等全方位的努力，有赖于医事主体双方及全社会的关注与通力改善。     

Subclinical course of adult visceral Niemann–Pick type C1 disease. A rare or underdiagnosed disorder?

Summary  We present the third case of Niemann–Pick disease type C without neurological symptoms. The patient was a 53-year-old woman without significant prior health problems who died of acute pulmonary embolism. Autopsy findings of hepatosplenomegaly, lymphadenopathy and ceroid-rich foam cells raised the suspicion of the visceral form of acid sphingomyelinase deficiency (Niemann–Pick disease type B; NPB) or a much rarer disorder, variant adult visceral form of Niemann–Pick disease type C (NPC). To verify the histopathological findings, SMPD1, NPC1 and NPC2 genes were analysed. Two novel sequence variants, c.1997G>A (S666N) and c.2882A>G (N961S) were detected in the NPC1 gene. No pathogenic sequence variants were found either in the SMPD1 gene mutated in NPB or in NPC2 gene. The pathogenicity of both NPC1 variants was supported by their location in regions important for the protein function. Both variations were not found in more than 300 control alleles. Identified sequence variations confirm the diagnosis of the extremely rare adult visceral form of Niemann–Pick disease type C, which is otherwise dominated by neurovisceral symptoms. Although only three patients have been reported, this (most probably underdiagnosed) form of NPC should be considered in differential diagnosis of isolated hepatosplenomegaly with foam cells in adulthood.

高压氧综合治疗持续植物状态30例疗效分析

目的评估高压氧综合治疗持续植物状态的疗效和探讨最佳治疗方案。方法回顾性分析了1999年—2005年应用高压氧治疗的30例持续植物状态病例,主要分析了原发病因、高压氧治疗次数以及高压氧治疗时机与疗效的关系。结果脑外伤组显效率和好转率明显高于非脑外伤组(P<0.05),开始治疗时间≤30d组及31～60d组好转率明显高于≥61d组(P<0.05)。结论高压氧综合治疗对脑外伤所致持续植物状态患者60d以内开始行高压氧治疗的患者疗效较好。     

Expression of innate immune complement regulators on brain epithelial cells during human bacterial meningitis

Background  

In meningitis, the cerebrospinal fluid contains high levels of innate immune molecules (e.g. complement) which are essential to ward off the infectious challenge and to promote the infiltration of phagocytes (neutrophils, monocytes). However, epithelial cells of either the ependymal layer, one of the established niche for adult neural stem cells, or of the choroid plexus may be extremely vulnerable to bystander attack by cytotoxic and cytolytic complement components.

顽固性下颌磨牙根尖周炎患者的治疗和护理讨论

目的治疗顽固性下颌磨牙根尖周炎。并尽量减少对牙周膜的机械性损伤。方法采用下牙槽神经阻滞麻醉,并配合局部麻醉。拔牙钳的尖置放于釉牙骨质界以上,采用颊舌向摆动的方式将患牙拔下。在不断滴有生理盐水的条件下,立即用高速车针磨除患牙根尖2￣3mm的牙体组织,根管内3￣5mm深的充填物要用圆钻将其清除,再用牙胶尖和氢氧化钙糊剂充填。将患牙再植入牙槽窝之前,务必用生理盐水将牙槽窝冲洗干净,要求严格控制在15分钟内完成再植,并尽量减少对牙周膜的机械性损伤。再植牙齿一般不需要夹板固定,必要时可采用缝线缝合固定。结果我们选择的5例患者,术后随访1￣2年,1例患者再植失败,4例患者再植成功。结论特异性再植术治疗顽固性下颌磨牙根尖周炎疗效理想,而且较易掌握。     

医改尚未成功,路在何方?

目前我国医疗制度改革尚未取得成功,这与计划经济向市场经济转轨这历史时期及卫生工作的特殊性有关,出现问题,甚至失误,在所难免。提出(1)医改的目的是确保全国人民健康,人人享有医疗保健。(2)把卫生系统推向市场,医疗机构商业化,不是医改的方向。(3)预防为主,健全预防医学制系。(4)国家增加投入。(5)制定公立及私立医院各项制度,保护医务人员的合法权益。(6)加强社区基层医疗机构的建设。
