In order to evaluate the Doppler spectrum of right ventricular outflow tract (RVOT) and left ventricular inflow tract (LVIT) there by to estimate pulmonary artery pressure (PAP) and pulmonary capillary wedge pressure (PCWP) for cor pulmonale (CP) in elderly, 21 patients (6>years ) with CP, 22 patients (>60 years) with chronic bronchitis (CB) and 15 healthy (H) subjects (>60 years) were studied. Results and conclusions: 1) The Doppler spectrum was obtained more easily and simply in RVOT than in main pulmonary artery. The isovolumic relaxation time was measured more easily by LVIT Doppler spectrum than by mechanocardiography. 2)RVOT spectrum may differ CP from CB and H (p< 0. 1). The features of RVOT Doppler for CP reveiled: shortened acceleration time(<100ms ), abnormal RPEP/RVET (>0. 4), increased PAP and pulmonary total resistance. 3) Normal PCWP did not support the diagnosis of left heart failure in the presence of dyspnea and rales in lungs. 4 ) Increased atrial natriuretic peptide in plasma, related to increased right atrial pressure resulted from pulmonary hypertension. 5) The sensitivity and specificity of RVOT Doppler for diagnosing CP were 90. 5% and 94. 6% respectively.

为了评价脉冲多普勒记录右心室流出道(RVOT)及左室流入道(LVIT)血流频谱以检测肺动脉压(PAP)和肺毛嵌压(PCWP)对老年肺心病的临床意义。研究老年肺心病(CP)21例、老年慢性支气管炎(CB)22例、健康老人(H)15名。结果和结论:1)在RVOT比在肺动脉主干内记录血流图容易成功,在LVIT测定左室等容舒张时间比心机图容易;2)RVOT血流频谱可将CP与CB及H区别开来(P<0.01)。CP的RVOT血流图的特点是,加速时间缩短,<100ms;右心室收缩时间间期异常,RPEP/RVET>0.4;由血流曲线计算的肺动脉压及即血管总阻力增高;3)有气短和肺湿性罗音,如PCWP不高,则不支持左心功能不全或舒张型心力衰竭;4)CP患者的血浆心钠素(ANP)显著升高。这反映肺动脉压和右心房压力升高;5)本文RVOT血流图诊断CP的敏感性为90.5%,特异性94.6%。

Objective:To study cytology stud in bronchoalveolar lavage fluid (BALF) from patients with asthma, chronic bronchitis (CB) and hypersensitivity pneumonitis (HP). Methods: Different cell count, T-cell subpopulation and lymphocytes expressing HLA-DR molecular of the BALF obtained from 16 patients with asthma, 15 patients with CB and 16 patients with HP were determined. Results: In asthma,the ratio of eosinophilia and lymphocytes expressing HLA-DR in BALF were significantly higher than those...

Objective:To study cytology stud in bronchoalveolar lavage fluid (BALF) from patients with asthma, chronic bronchitis (CB) and hypersensitivity pneumonitis (HP). Methods: Different cell count, T-cell subpopulation and lymphocytes expressing HLA-DR molecular of the BALF obtained from 16 patients with asthma, 15 patients with CB and 16 patients with HP were determined. Results: In asthma,the ratio of eosinophilia and lymphocytes expressing HLA-DR in BALF were significantly higher than those in CB and HP (P <0. 01 ). In HP,the ratio of lymphocytes and CD8+ cells in BALF were significantly higher than those in asthma and CB (P <0. 01 ). In CB,the ratio of neutrophils in BALF was significantly higher than that in asthma and HP (P <0.01 ). Conclusion: Cytological examination of BALF is effective in differentiating asthma, CB and HP,and provides usful infomation about different pathogenetic processes of the three diseases.

目的:为了解支气管肺泡灌洗液(BALF)细胞学在哮喘、慢性支气管炎(慢支)和过敏性肺炎(HP)的特征。方法:分别对16例哮喘,15例慢支,16例过敏性肺炎患者的BALF中细胞分类计数、T淋巴细胞亚群及HLA-DR进行了测定。结果:哮喘患者BALF中嗜酸细胞及淋巴细胞表面HLA-DR明显高于慢支和过敏性肺炎组(P<0.01);过敏性肺炎的淋巴细胞、CDS8+细胞明显高于哮喘和慢支组(P<0.01);慢支组中性粒细胞明显高于哮喘和过敏性肺炎组(P<0.01)。结论:测定BALF中细胞分类计数、T细胞亚群及HLA-DR,对鉴别哮喘、慢支和过敏性肺炎有指导作用,对研究各自不同的病理生理学过程也可提供有益的线索。

Purpose To investigate inflammation theory of asthma, distinguish the pathological nature of airway inflammation between asthma and chronic bronchitis (CB), and to provide pathological basis for clinical diagnosis and treatment. Methods By passing the fiberoptic bronchoscope into large airway airway, endobronchial biopsies were obtained in 14 subjects with asthma and 13 subjects with CB. For comparison, 5 normal bronchial autopsies were also abtained. All these samples were assessed...

Purpose To investigate inflammation theory of asthma, distinguish the pathological nature of airway inflammation between asthma and chronic bronchitis (CB), and to provide pathological basis for clinical diagnosis and treatment. Methods By passing the fiberoptic bronchoscope into large airway airway, endobronchial biopsies were obtained in 14 subjects with asthma and 13 subjects with CB. For comparison, 5 normal bronchial autopsies were also abtained. All these samples were assessed for microscopical evidence of inflammation by assigning them scores according to the quantitation of inflammatory cell. Eight cases of asthma and eight cases of CB were observed electron microscopically. Results Comparing with normal autoposies, the airway epithelia in asthma and CB demonstrated more evidence for damage, hyperplasia and squamous metaplasia (P<005). Further more, mucosa edema, fibrosis as well as thickness of basement membrane were obvious in asthma and CB subjects. In addition, Although there were many of inflammatory cells in asthma and CB, eosinophils and mast cells made up the majority of the infiltrating cells in asthma (P<005). In asthma mast cell degranulation was observed electron microscopically in different degree, but in CB it was not observed. Conclusion Both asthma and CB are chronic airway inflammation, but there are many clinical and pathological differences between them.

目的:探讨哮喘的炎症学说,并比较支气管哮喘(简称哮喘)与慢性支气管炎(简称慢支)气道炎症的病理异同。方法:经纤支镜行大气道粘膜活检将14例哮喘和13例慢支病人支气管粘膜活检组织以及5例无呼吸病史的意外死亡者尸体解剖的相应部位气道粘膜组织,通过常规病理切片,进行显微镜下双盲观察,采用多指标的定量病理计分及统计学处理,进行比较研究。其中8例哮喘、8例慢支进行了电镜观察。结果:与正常组相比,哮喘组和慢支组气道粘膜上皮均有不同程度的损伤、增生和鳞状上皮化生(P<005),并且在粘膜水肿、纤维化程度和基底膜厚度方面均有明显改变(P<005)。哮喘与慢支相比,哮喘的基底膜明显厚于慢支(P<005)。哮喘与慢支均在其粘膜和粘膜下层有明显的各种炎细胞的浸润,但哮喘组的嗜酸性粒细胞和肥大细胞高于慢支组(P<005)。电镜下可见哮喘组有肥大细胞不同程度的脱颗粒现象,而慢支组未见到。结论:哮喘和慢支均为气道慢性炎症,但二者在临床及病理特点上存在着一定的差异,这为临床诊断和治疗哮喘提供了一定的病理学依据。
