简介：　　【摘要】 目的：研究多巴丝肼片（美多巴）联合盐酸普拉克索速释片治疗帕金森的临床效果及安全性。方法：研究对象选取笔者所在医院 2015年 5月 -2016年 7月收治的 78例帕金森病患者，并采用随机数字法将其均分为对照组和观察组，每组 39例。对照组患者采用美多巴治疗，观察组患者采用美多巴联合盐酸普拉克索速释片治疗，比较两组患者治疗后的临床效果及不良反应发生率。结果：观察组的治疗总有效率 87%，明显高于对照组的 62%，差异有统计学意义（字 2=6.72， P<0.05）；观察组的不良反应发生率 5%，明显低于对照组的 23%，差异有统计学意义（字 2=5.19， P<0.05）。结论：美多巴联合盐酸普拉克索速释片治疗帕金森病的临床效果显著，是值得在临床上推广使用的安全可靠的治疗方法。  

简介：摘要目的探讨肺栓塞误诊常见原因分析及第二代炫速双源CT肺动脉成像联合双能量肺灌注在避免误诊中的临床价值以降低误诊率、病死率,提高对肺栓塞的认识和诊断.方法回顾性分析３３例经第二代炫速双源CT肺动脉成像联合双能量灌注成像扫描诊断明确的肺栓塞的临床资料及误诊情况,就误诊原因加以分析.结果肺栓塞常见误诊原因为临床医生对肺栓塞的认识或重视不足;肺栓塞常起病隐匿,症状缺乏特异性;且如合并心、肺慢性疾病掩盖了肺栓塞的临床表现.第二代炫速双源CT肺动脉成像联合双能量灌注成像扫描时间短,危重患者及急诊排查均可适用,它一站式检查同时完成CTPA及肺通气灌注扫描两项检查,在临床上可早期确诊急性肺栓塞,提高肺栓塞的临床确诊率及减少临床误诊率.结论加强对肺栓塞的认识,对疑似肺栓塞症状患者,特别对有肺栓塞高危因素的人群,应尽早行特异性检查如第二代炫速双源CT肺动脉成像联合双能量灌注成像以提高确诊率和早期抢救成功率.关键词肺栓塞;误诊;第二代炫速双源CTAnalysisofclinicalmisdiagnosisin３３patientswithacutepulmonaryembolismandSecondgenerationofHyun－speeddual－sourceCTmisdiagnosisofpulmonarylungperfusionImagingincombinationwithenergyinavoidingmisseddiagnosisanditsclinicalvalueBaotouofInnerMongoliaCentralHospitalJiaXiaoQingWangYuanChangXiaoYueYaoXingYanDingLinFangCode０１４０４０AbstractObjectiveStudyoncommoncauseofpulmonaryembolismmisdiagnosisanalysisandsecondgenerationHyun－speeddual－sourceCTmisdiagnosisofpulmonarylungperfusionImagingincombinationwithenergytoavoidmisdiagnosisofclinicalvalueinordertoreducerates,mortalityrates,increasedawareＧnessanddiagnosisofpulmonaryembolism??MethodRetrospectiveanalysisof３３casesofdiagnosedpulmonaryembolismofclinicaldataandmisdiagnosis,missed,misseddiagnosisanalysisMethodsRetrospectiveanalysisof３３casesofsecondgenerationofHyun－speeddual－sourceCTofpulmonaryperfusionImaＧgingincombinationwithenergyscanindiagnosisofspecificpulmonaryembolismofclinicaldataandmisdiagnosis,missed,misseddiagnosisanalysis??ResultsCommonmisdiagnosisforpulmonaryembolismofclinicaldoctorofpulmonaryembolismawarenessorinsufficientattention;pulmonaryembolismofteninsidiousonset,symptomsoflackofspecificity;andcombinedheartandlungchronicdiseasemaskedtheclinicalmanifestationsofpulmonaryembolism??SecondgenerationofHyun－speeddual－sourceCTofpulmonaryperfusionImagingincombinationwithenergyscantimeisshort,criticallyillpatientsandemergencytroubleＧshootingcanbeapplied,One－stopcheckbothCTPAandpulmonaryventilationperfusionscanchecksearlyintheclinicaldiagnosisofacutepulmonaryembolism,improvetheclinicaldiagnosisofacutepulmonaryembolismandreduceclinicalmisdiagnosisrate??ConclusionStrengthentheawarenessofpulmonaryembolism,thesymptomsofpatientswithsuspectedpulmonaryembolism,Especiallytohaveriskfactorsofpulmonaryembolisminthepopulation,shouldasfarasearlyspeＧcificlaboratoryexaminationsuchasthesecondgenerationHyunspeeddualsourceCTpulmonaryangiographycombinedwithdualenergyperfusionimaginginorＧdertoKiemyprwoovredsthediagnosisrateandearlyrescuesuccessrate??pulmonaryembolism;misdiagnosis;SecondgenerationofHyun－speeddual－sourceCT中图分类号R５６３文献标识码A文章编号１００８－６３１５(２０１５)１２－０４１１－０２
