[The epidemiologic characteristics of patients with severe acute respiratory syndrome (SARS)].

Objective: To study the epidemiologic characteristics of patients with Severe Acute Respiratory Syndrome (SARS) and to investigate the transmission way of the disease.

Methods: A total of 80 clinically diagnosed SARS patients was enrolled in this study.

Results: The result showed that 72/80 patients had exposed to SARS patient, and the least contact time was only 20 minutes, the average incubation period was (7.

[A study of the expression of CD(44) in pneumocytes in pulmonary sarcoidosis].

Objective: To study the expression of CD(44) in pneumocytes in pulmonary sarcoidosis.

Methods: CD(44) and AE(1)/AE(3) were detected by immunostaining in lung tissues from 21 cases of pulmonary sarcoidosis, 5 cases of tuberculosis, 4 cases of idiopathic interstitial fibrosis, 3 cases of Wegener's granulomatosis and 8 normal controls. The numbers of CD(44) positive cells and AE(1)/AE(3) positive cells (total alveolar epithelial cells) per three high-power fields were counted, and the ratio of CD(44) cells to AE(1)/AE(3) cells (84 +/- 6) were calculated.

[Electroencephalogram spectral power analysis of obstructive sleep apnea syndrome patients before and during continuous positive airway pressure therapy].

Objective: To investigate the instant effects of continuous positive airway pressure (CPAP) on EEG spectral power changes in obstructive sleep apnea syndrome (OSAS) patients.

Methods: 26 OSAS patients were included. The diagnosis was made by polysomnography (PSG).
