目的探讨外周血红细胞分布宽度（red blood cell distribution width，RDW）与冠状动脉病变严重程度的关系。方法选择临床拟诊冠心病（无贫血）患者273例，冠状动脉造影结果阳性170例，阴性103例。阳性病例按Gensini积分评价冠状动脉病变严重程度，并按Gensini积分分为三组，<20分组、20~40分组、>40分组，分别比较各组间外周血RDW水平。结果冠状动脉造影阳性组患者外周血RDW水平明显高于阴性组（P<0.01），且随Gensini积分的增加RDW值逐渐升高，Gensini积分>40分组与<20分组比较差异有统计学意义（P<0.01），Gensini积分>40分组与20~40分组比较差异有统计学意义（P<0.05），而Gensini积分<20分组与20~40分组比较差异无统计学意义。结论 RDW与冠状动脉病变严重程度密切相关，可以作为预测冠状动脉病变严重程度的指标之一。
Objective:To evaluate the clinical effects 0f mandibular overdentures supported by two implants.Methods:From November 2003 to October 2010,52 cases of mandibular edentulous were received by overdentures supported by two implants.Among them,39 were male,13 were female.The age of patients was from 46 to 72.104 implants were implanted in the canines zone.The attachments types of overdentures were 30 ball-sockets,11magnets and 11 Locators.Clinical evaluation and radiographs were assessed.Results:No implants were loosen and lost.All of the implants were stable and excellent osseointegration.The overdentures were stable and functional effectively.The retentive force of 3 ball-sockets was reduced after 2 years and reinforced by adjusted.4 magnets were lossen and reinforced by self-curing resin.The base of overdentures of 4 patients were fracture.The area of fracture lied in combination of implant-attachment.No attachments were lossen and fracture.Conclusions:Overdenture supported by two implants is effective method for mandibular edentulous,especially for alveolar bone absorbed severely.
Objective To analyze the changes of T lymphocyte subsets,B lymphocyte and NK cells in pneumonia children infected by parainfluenza virus types 3(PIV3).Methods Multi-pathogen detection using direct fluorescence antibody test(DFA),clear etiology diagnosis.T lymphocyte subsets,B lymphocyte and NK cells in peripheral blood in part of patients were examined by flow cytometry.Results In,There was no significant difference in CD3+T,CD4+T,CD8+T cells and CD19+B cells between the patients with PIV3 pneumonia and the controls.But the ratio of NK cells were lower in group PIV3 than those in the controls(P0.05).In contrast,the ratio of CD4+/CD8+ increase in group PIV3 than those in the controls(P0.05).Conclusion Parainfluenza virus types 3(PIV3)cases of pneumonia children cellular immune disorders.
目的探讨婴儿支气管肺炎与胃扭转的关系。方法回顾性分析婴儿肺炎合并胃扭转23例病例资料,总结诊断及治疗要点。结果肺炎合并胃扭转者予以体位疗法,可缓解抗生素治疗效果不佳的肺炎患儿症状。结论肺炎患儿病程较长且抗感染等治疗效果不理想、平素吐奶较频繁者应及时行上消化道钡餐检查,以明确是否合并胃扭转,予以相应体位疗法可缓解临床症状。
Objective To explore the causes of misdiagnosis and missed diagnosis of mediastinal tumor in children.Methods The clinical data of 25 children with mediastinal tumor in the Children's Hospital affiliated to Soochow University was analyzed retrospectively.Results These illnesses which led to mediastinal tumor included teratoma(10),lymphoma(7),neuroblastoma(4),thymoma(3),and neurofibroma(1).Most cases were misdiagnosed as pneumonia because of repeated coughing,wheezing,and fever.Conclusion The causes of their misdiagnosis and missed diagnosis were that their manifestations were not typical or were covered by pneumonia,as well as inadequate understanding by clinicians where their chest X-ray film,and CT do not attract enough attention.Therefore clinicians should be on high alert to do the corresponding inspection as early as possible to confirm the diagnosis.
