  • The diagnosis of chronic obstructive lung disease using pulmonary function test is notcompletely the same with the criteria of obstructive ventilatory defect

    COPD是以不完全可逆性气流受限为特征的进展性肺疾病, 与肺部对香烟烟雾等有害气体或有害颗粒的异常炎症反应有关。病理改变存在于外周气道、中央气道、肺实质和肺血管系统等, 也可引起肺外的不良效应, 但外周气道病变和功能异常是导致不完全可逆气流受限的主要原因。国内外采用吸入支气管舒张剂后一秒率( FEV1/FVC) 小于70%来进行定性诊断。

  • Value of Pulmonary Ventilation Function Test in Evaluating the Prognosis of Cardiac Surgery

    Objective To assess the value of pulmonary ventilation test in evaluating the prognosis of cardiac surgery patients. Methods Data were collected retrospectively from consecutive patients with coronary heart disease or valvular disease, who were prepared for cardiac surgery in Zhongshan Hospital from January 2007 to December 2008. The main outcome indices were mortality of surgery, the prolonging time of using artificial airway ( ≥3 days) , and the prolonging time in intensive care units ( ICU) ( ≥5 days) . Then the relationship between the poor outcome and ventilation disorder was analyzed. Results In the 422 cases,the incidence of ventilation disorder was 55% , included 27. 5% restrictive ventilation disorder, 15. 6% obstructive ventilation disorder, and 11. 8% mixed ventilation disorder. And the severity of pulmonaryventilation disorder was mild of 34. 6% , moderate of 15. 2% , and severe of 5. 2% . Among the 42 patients who gave up surgery,50% were due to ventilation dysfunction, and the patients were prone to give up surgery with the deterioration of pulmonary function( P lt; 0. 001) . But comparing with the patients with normal pulmonary function, the risk of poor outcome after surgery did not significantly increase in the patients with ventilation disorder ( P gt; 0. 05 ) . The logistic regression analysis indicated that cardiopulmonary bypass ( CPB) was an absolute risk factor ( P lt; 0. 05) . Conclusions The incidence of ventilation disorder in patients with cardiac disease is quite high. Severe pulmonary ventilation disorder is the significant cause of giving up surgery, but may be not the absolute contraindication of cardiac surgery.

  • Clinical analysis of community acquired pulmonary cryptococcosis

    Objective To investigate clinical characteristics of community acquired pulmonary crypyococcosis(PC).Methods A total of 30 cases of PC diagnosed at Zhongshan Hospital of Fudan University from Jan 2003 to Dec 2007 were retrospectively analysed.All cases were identified by pathological study.Results The patients consisted of 19 males and 11 females,with median age of 44 years(16 to 70 years),66.7% of whom without underlying deseases and with normal immune function.9 patients(30%) were asymptomatic,and 21 patients(70%) had respiratory and/or constitutional symptoms.The most common symptoms were dry cough(16.7%),expectoration(46.7%),fever(23.3%),chest pain(13.3%) and dyspnea on exertion(13.3%).All symptoms were mild and often showed a self-limiting trend.The common imaging features were nodule and mass,either solitary or multiple(53.3%),infiltrates and consolidation(40%) or diffused and mixed lesions.Non-caseous granulomas was the main character of patholgical study(96.7%),in which 93.1% with multinucleated giant cells containing abundant vacuolus yeast forms with the periodic acid schiff(PAS) reaction and/or Grocott Gomori’s methenamine silver(GMS) staining postive.Only one case found Cryptococcus neoformans spores in biopsy tissue smear and another in sputum smear.16.7% of the patients had positive biopsy tissue cultures for Cryptococcus neoformans,and 3.3% were positive of sputum cultures.15 patients underwent latex agglutination test for pulmonary cryptococcosis,and 93.3% were positive.Conclusions Some immunocompetent healthy people may compromised with community acquired PC with mild symptoms or even not at all and heterogeneous imaging appearance.Pathology,etiology,and serology were valuable diagnostic tools.

  • mpact of Using Different FEV1 /FVC as Cut-off Point in the Qualitative Diagnosis on the Prevalence of Chronic Obstructive Pulmonary Disease

    Objective To investigate the impact of using low limit of normal( LLN) for FEV1 /FVC ratio and fixed ratio ( 70% ) as cut-off point in the qualitative diagnosis on the prevalence of chronic obstructive pulmonary disease( COPD) . Methods An epidemiological study was carried out in preoperative patients who received pulmonary function test in Zhongshan hospital fromNovember 6, 2007 to December 30, 2007. 339 patients were enrolled and diagnosed as COPD by different diagnostic criteria as follows: ①GOLD criteria; ②FEV1 /FVC
