重视和总结我国临床诊治甲型H1N1流感的经验
目的 探讨妊娠期甲型H1N1流感的临床特点。 方法 对乌鲁木齐市妇幼保健院2009年11月-2010年1月收治的妊娠期甲型H1N1流感临床资料进行回顾性分析。 结果 同期住院非甲流孕产妇1 856例,确诊甲型H1N1流感52例,发病率2.7%。妊娠期甲型H1N1流感的发热时限及不同孕期与病程时限均无相关关系。使用磷酸奥司他韦(达菲)治疗23例,较未使用此药物患者病程显著缩短[(4.79±2.04) d比(7.26±3.77) d,Plt;0.05]。合并肺炎6例,病程较无合并症患者显著延长[(9.83±4.70) d比(5.37±2.54) d,Plt;0.05]。 结论 妊娠期甲型H1N1流感应予以高度重视,在早预防、早诊断及早治疗的基础上,提早预防合并症的发生。明确诊断后及早使用磷酸奥司他韦可缩短疗程。
In order to investigate immune protection against swine-origin influenza virus (S-OIV) A H1N1, the helper-dependent adenovirus vector (HDAd) system was exploited to construct recombinant HDAd encoding hemagglutinin (HA). The HA gene was synthesized and cloned to the HDAd backbone. Then, the HDAd/HA DNA molecules were transfected into 293Cre4 cells with calcium phosphate. The cells were infected by helper virus 16 hours after the transfection. The 293Cre4 cells were coinfected with HDAd/HA and the helper virus for large-scale preparation of HDAd/HA. The HDAd/HA was obtained and purified twice with CsCl density ultracentrifugation and observed morphologically under transmission electron microscope, and the expression of HA protein was analyzed with RT-PCR. Recombinant HDAd/HA expressing HA protein was successfully constructed which could pave the way for in vivo investigation on immunogenicity and efficacy against S-OIV A H1N1 infection.
糖皮质激素在甲型H1N1流感中的应用探讨
目的:通过对首例甲型H1N1流感密切接触者临床医学观察发现二代患者,为大规模临床医学观察积累经验和参考。方法:对首例甲型H1N1流感患者密切接触者115例的临床医学观察资料进行回顾性分析。结果:115例密切接触者中,有6人出现不同程度咽充血、咽部疼痛症状,其中1例为糖尿病患者、2例为高血压患者;1例左前臂疱疹,1例口腔溃疡,4例结膜充血;观察第3天1例出现精神抑郁,1例出现情绪激动;观察第4天2例多次要求提前解除隔离,多例关心何时解除隔离。七日医学观察期间115例密切接触者均无咽痛、咳嗽、鼻塞等症状,体温均正常,情绪稳定,未发现二代患者。结论:对甲型H1N1流感患者的密切接触者进行临床医学观察是必要的,有助于发现二代患者,疾控中心(CDC)采样与临床医学观察和心理干预的有效结合,给传染病医学观察提供宝贵的经验和有效的工作模式。
【摘要】 目的 总结甲型H1N1流感病毒性肺炎患者的胸部X线和CT表现特征。 方法 回顾分析2009年3月-11月3例经临床表现及病原学检查证实的甲型H1N1流感病毒性肺炎的胸部X线、CT表现。 结果 肺部病灶多呈散在小片状高密度影,边缘模糊,邻近胸膜;病变最常累及肺基底段;病灶多有少量胸腔积液;病灶有扩散迅速,合理用药后消失较快的特点;病灶吸收落后于临床表现。 结论 甲型H1N1流感病毒性肺炎的X线、CT表现具有一定的特点,总结并掌握这些特点,有利于早期诊断。其确诊有赖于实验室检查和流行病学调查。【Abstract】Objective To explore the chest X-ray, CT manifestations of pneumonia of patients with influenza virus A/H1N1 infection. Methods The pulmonary X-ray and CT findings of 3 patients who were confirmed by laboratory results and epidemiology with infection of influenza virus A/H1N1 were retrospectively analyzed between March 2009 to November 2009. Results Both sides of the lung field showed many small cloudy infiltration in chest X-ray and CT film. The lesions of the lung were mostly near the pleural. They were often found in basal segment. Pleural effusion may be observed. Radiology dynamic changes showed the diffusion of the lesions of the lung was quick in a short time, and scattered and disappeared quickly after rational use of drugs. The lesions vanished later than clinical disappearance. The lesions of the lung may appear fibrosis at the period of the end. Conclusion Some radiographic characteristics exist in the pneumonia of patients with influenza virus A/H1N1 infection. It will be helpful for early diagnosis when getting familiar with its X-ray and CT manifestations, but the final diagnosis depends on the laboratory results and epidemiological history.
