Objective To evaluate the clinical value of bronchoscopy lung biopsy Combined with brush cytology .Methods Collected 113 cases of diffuse or clinical cases of peripheral pulmonary disease examined by bronchoscopy lung biopsy Combined with brush cytology with no X-ray guiding during January 2011 to December 2012 .And the inspection results and the corresponding clini-cal data were retrospectively analyzed.Results In 113 cases 73 cases made a definite diagnosis, diagnostic positive rate was 64.60% in total, include 96.02% of diffuse patchy shadows, 72.13% of diffuse millet or nodular, 54.12% of local infiltration fo-cal, 32.11% of diffuse grid or ground glass honeycomb lesion, 28.26% of local tumor nodules.Conclusion There is significantly clinical diagnosis value of bronchoscopy lung biopsy Combined with brush cytology to examine diffuse and peripheral pulmonary dis-ease.

OBJECTIVE To study the risk factors of pulmonary infection and prognosis in elderly cerebral apoplectic patients. METHODS A retrospective survey on 541 elderly cerebral apoplectic patients was analyzed to investigate the rate of pulmonary infection,the type and the severity of cerebral apoplexy,the underlying disease,disturbance of consciousness,invasive operation and the prognosis. RESULTS The most of the pulmonary infections in elderly cerebral apoplectic patients were nosocomial infection.The rate of infection was high and related to many factors. CONCLUSIONS The result showed that the pulmonary infection in elderly cerebral apoplectic patients is caused by many risk factors.Controlling the rate of pulmonary infection can help us to succeed in treating cerebral apoplexy.

OBJECTIVE To analyze the bacterial distribution and drug-sensitivity in sputum bacterial culture of the hospitalized patients with respiratory tract infection in the department of respiratory medicine to help reasonably choose the antibiotics and reduce the nosocomial infection rate. METHODS The bacterial infection of all the hospitalized patients with lower respiratory tract infection in the department of respiratory medicine from 2004 to 2005 was analyzed retrospectively and compared with all the patients of the hospital. RESULTS The nosocomial infection rate of the department of respiratory medicine in 2005 was 10.18%,which was higher than the rate of nosocomial infection of the whole hospital(3.09%).The Gram-negative bacteria were the main ones infected through respiratory tract.What should be paid attention to was the comparably higher fungal infection rate in 2005.The main Gram-negative bacteria were dominated by Pseudomonas aeruginosa.The most sensitive drug was piperacillin+ tazobactam in 2004 and aminoglycoside antibiotics in 2005.The Gram-positive bacteria were most sensitive to vancomycin. CONCLUSIONS The nosocomial infection is dominated by lower respiratory tract infection in the department of respiratory medicine.The nosocomial infection rate,dominated by Gram-negative bacteria is high.In order to decrease nosocomial infection rate,cross infection should be avoided,sensitive antibiotics be chosen,body resistance be enhanced and hospital stay be reduced.

Objective To detect the change of hemorrheology and prethromboticstate markers levels in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and to explore the pathogenic mechanisms of cardio-cerebrovascular thromboembolic diseases in OSAHS patients. Methods Polysomnography was performed in 86 patients with OSAHS and in 20 control subjects matched for age and body mass index. The patients with OSAHS were divided into mild group , moderate group , and severe group according to the apnea hypopnea index (AHI). Hemorrheology and prethromboticstate markers levels were measured in all the subjects for correlation analysis. Results The whole blood viscosity, erythrocyte aggregation index, and erythrocyte electrophoresis time in mild OSAHS group , moderate OSAHS group and severe OSAHS group were significantly higher than those in the control group. The whole blood viscosity, erythrocyte aggregation index, and erythrocyte electrophoresis time were also significantly different between the three OSAHS groups , increasing with the severity of OSAHS. Plasma viscosity was not significant difference between OSAHS groups and the control group. Plasma D-D , AT-Ⅲ and vWF levels were also not significant difference between OSAHS groups and the control group. Conclusions The change of hemorrheology in OSAHS patients may contribute to the vulnerability of patients to cardio-cerebrovascular thromboembolic diseases.
