Objective To study the clinical diagnosis of pulmonary sarcoidosis,in order to improve the diagnostic accuracy.Methods The clinical data of 20 patients with pulmonaty sarcoidosis was retrospectively analyzed .Results There were 7 males and 13 females in this group with 20 patients age 14～63 years old mean 41 6 years,main symptom was cough(n=16),wet cough(n=8),hard breathing(n=6),fever(n=6),erythema(n=4),visual change(n=3),fatigue(n=2),headache(n=1),X-ray and CT examination results were as followes:bilateral hilar hilifuge larger than normal 19 cases,single hilifuge larger than normal 1 cases,mediastinal lymphadenectasis 12 cases,interstial pulmonary fibrosis 6 cases,bilateral little quantity pleural effusion 3 cases.Bronchofiberoscopy diagnosis in 14 cases,live tissue examination of skin,mucosa and lymph node in 8 cases,Kveim test positive 3 cases,SACE 69 8?12 6?/L.Conclusions Clincal symptom of pulmonary sarcoidosis was not typical,high morbidity was occured among females.In combination of clinical symptom,X-ray examination and bronchofiberoscopy pathologic examination was required to improve diagnosis rate.The therapy of adrenocortical hormone could acquire good efficacy.

Objective To evaluate the efficacy and safety of intermittent use of low-dose urokinase in the treatment of pulmonary embolism. Methods Forty-two patients with acute pulmonary embolism were divided into UK group with UK 10 000 U/(kg·d),7 days and rt-PA group with rt-PA 50 mg/2 h randomly. The efficacy was determined by the improvement of right heart dysfunction and perfusion defect 8 d and 14 d after the treatment. The bleeding incidence, death rate and PE recurrence were also evaluated. Results Differences of right heart dysfunction and perfusion defect between UK group and rt-PA group indicated no statistical significance (P >0.05).The rate of bleeding in UK group was lower than that of rt-PA group. Conclution The intermittent use of low-dose urokinase in the treatment of pulmonary embolism exhibits similar efficacy as rt-PA.
