5DF血球分析仪检测白细胞分类计数与瑞氏染色镜检结果对比研究 总被引:3,自引:2,他引:3
目的 探讨5DF血球分析仪白细胞分类计数与传统的瑞氏染色镜检计数结果之间的差异。方法 用5分类血球分析仪和瑞氏染色法同时对10 0份血样进行分类计数,并用统计学分析研究。结果 中性粒细胞、嗜酸、嗜碱性细胞和淋巴细胞分类计数两法无明显差异(P均>0 .0 5 ) ,但单核细胞分类计数仪器法比镜检法结果偏高(P <0 .0 0 1)。结论 对于一般血液常规检查可选用仪器法筛查,而血液系统疾病或某种原因引起的细胞结构改变应选用镜检法。 相似文献

Background
The underlying mechanisms sustaining human persistent atrial fibrillation (PsAF) is poorly understood.Objectives
This study sought to investigate the complexity and distribution of AF drivers in PsAF of varying durations.Methods
Of 135 consecutive patients with PsAF, 105 patients referred for de novo ablation of PsAF were prospectively recruited. Patients were divided into 3 groups according to AF duration: PsAF presenting in sinus rhythm (AF induced), PsAF <12 months, and PsAF >12 months. Patients wore a 252-electrode vest for body surface mapping. Localized drivers (re-entrant or focal) were identified using phase-mapping algorithms.Results
In this patient cohort, the most prominent re-entrant driver regions included the pulmonary vein (PV) regions and inferoposterior left atrial wall. Focal drivers were observed in 1 or both PV regions in 75% of patients. Comparing between the 3 groups, with longer AF duration AF complexity increased, reflected by increased number of re-entrant rotations (p < 0.05), number of re-entrant rotations and focal events (p < 0.05), and number of regions harboring re-entrant (p < 0.01) and focal (p < 0.05) drivers. With increased AF duration, a higher proportion of patients had multiple extra-PV driver regions, specifically in the inferoposterior left atrium (p < 0.01), superior right atrium (p < 0.05), and inferior right atrium (p < 0.05). Procedural AF termination was achieved in 70% of patients, but decreased with longer AF duration.Conclusions
The complexity of AF drivers increases with prolonged AF duration. Re-entrant and focal drivers are predominantly located in the PV antral and adjacent regions. However, with longer AF duration, multiple drivers are distributed at extra-PV sites. AF termination rate declines as patients progress to longstanding PsAF, underscoring the importance of early intervention. 相似文献17.

BackgroundDengue fever (DF) is the most rapidly spreading mosquito-borne viral disease. Practical vaccines or specific therapeutics are still expected. Environmental factors and genetic factors affect the susceptibility of Dengue virus (DV) infection. Asthma is a common allergic disease, with house dust mites (HDMs) being the most important allergens. Asthmatic patients are susceptible to several microorganism infections.MethodsA nationwide population-based cohort analysis was designed to assess whether to determine whether asthma can be a risk factor for DF.ResultsUnexpectedly, our data from a nationwide population-based cohort revealed asthmatic patients are at a decreased risk of DF. Compared to patients without asthma, the hazard ratio (HR) for DF in patients with asthma was 0.166 (95% CI: 0.118–0.233) after adjustment for possible confounding factors. In the age stratification, the adjusted HR for DF in young adult patients with asthma was 0.063. Dendritic cell-specific intercellular adhesion molecule 3-grabbing non-integrin (DC-SIGN) of dendritic cells (DCs) is an important entry for DV. Through another in vitro experiment, we found that HDM can diminish surface expression of DC-SIGN in monocyte-derived DCs and further decrease the cellular entry of DV.ConclusionsDecreased DC-SIGN expression in DCs of allergic asthmatic patient may be one of many factors for them to be protected against DF. This could implicate the potential for DC-SIGN modulation as a candidate target for designing therapeutic strategies for DF. 相似文献

目的 初步探讨糖尿病足中医不同证型与下肢动脉彩超的关系.方法 收集糖尿病足病例60例,非糖尿病住院病人45例作为对照组,记录相应下肢动脉彩超结果,并进行初步相关性分析.结果 与非糖尿病组比较,糖尿病足组双下肢动脉内径均较窄,其中股总动脉、腘动脉、胫前动脉、胫后动脉内径差异有统计学意义(P<0.01);分型研究中,气阴两虚瘀阻组各下肢动脉内径最窄,与其他证型组比较差异有统计学意义(P<0.01或P<0.05).结论 糖尿病足中医不同征型与下肢动脉彩超有一定的相关性,糖尿病足表现为各下肢动脉内径变窄,以气阴两虚瘀阻型明显. 相似文献

Low-density lipoprotein (LDL) apheresis is performed in patients with homozygous familial hyper-cholesterolemia who lack LDL receptors and with heterozygous familial hypercholesterolemia who are LDL receptor deficient with documented, symptomatic coronary artery disease who are resistant to diet changes and maximum drug therapy. LDL apheresis can reduce or abolish anginal symptoms and improve coronary lesions. Several reports reveal the improvement of insufficient peripheral blood flow. By extensively removing blood LDL and changing coagulation factors and various vasoactive substances, LDL apheresis improves blood rheology and thereby peripheral circulation. It seems worth trying on all patients with arteriosclerotic lesions, even if they are normocholesterolemic. 相似文献

目的探讨DF方案化疗合并后程加速超分割放疗治疗中、晚期食管癌的临床应用价值。方法经病理确诊的中、晚期食管癌90例随机分为两组(单放组和化放组),每组45例;放疗均采用6MVX线外照射,单放组常规分割治疗2Gy/次,5次/周,全疗程总剂量70Gy;化放组放疗前2/3疗程常规放疗2Gy/次,5次/周,共40Gy,后1/3疗程改用加速超分割治疗,1.5Gy/次,2次/天,间隔6h以上,全疗程总剂量70Gy,前程配合DF方案化疗,治疗结束后,按照食管癌诊治规范标准,比较两组疗效及1、3年生存率。结果单放组CR44%,PR51%,1、3年生存率分别为42%、28%;化放组CR51%,PR57%,1、3年生存率分别为74%、53%,经统计学处理两者生存率比较差异有统计学意义(P<0.05),毒副作用两组比较差异无统计学意义(P>0.05)。结论后程加速超分割放疗加DF增敏化疗能明显提高中、晚期食管癌的近期疗效及1、3年生存率,且不增加毒副反应,值得推广应用。 相似文献
