Objective The purpose of this study was to describe the clinical and CT features in Cryptogenic organizing pneumonia(COP),and method of managemant.Methods We reviewed characteristics of clinical,laboratory,chest CT and pulmonary function test of 6 patients with histologically proven COP,and evaluated their therapeutic response to corticosteroids.Results Most patients of 6 cases manifested as a persistent nonproductive cough,exerting dyspnea,pyrexia,malaise,and weight loss clinically.Less common symptoms include pleuritic chest pain and hemoptysis.Chest CT manifestations included ground-glass opacity,consolidation,diffusing reticular infiltration of parenchyma,pleural effusion,cavitation and migration.The patients had high level of peripheral WBC number,erythrocyte sedimentation,and C-reactive protein.Pulmonary function tests showed a impairment of restrictive pattern and diffusion capacity.All but one Patients responsed well to corticosteroids.Conclusions COP is a rapidly developing pneumonia-like illness characterized by lung inflammation,The clinical doctor must always be aware of the full view of COP so as to achieve successful diagnosis.Most of the patient can recover with corticosteroids therapy.

Objective To evaluate the clinical features and various diagnostic methods for sarcoidosis.Methods The data of 28 cases with sarcoidosis confirmed by pathology were reviewed and analized,and different diagnostic methods were compared.The disease was evaluated by regular serological tests,chest X ray film,chest high resolution computed topography(HRCT),bronchofibroscopy,and pulmonary function test.Results These patients shared a typical clinical presentation,consisting of dyspnea,cough,subskin nodes,enlargement of peripheral lymphnodes and splenomegaly.Laboratory test revealed elevated serum blood sedimentation,alkali phosphatase,Angiotensin-converting,and urine calcium.The saricoidosis was confirmed by pathological biopsy for bronchial mucosa,lung tissues,peripheral lymphnodes,subskin nodes biopsies and spleen.HRCT showed its superiority to traditional X ray film examination in fingding early staging chest sarcoidosis.Conclusions Chest HRCT and bronchopulmonary biopsy through bronchofibroscopy possess significant clinical value for sarcoidosis diagnosing and staging.And extropulmonary lessions biopsy also plays a complementary role to some extent.

Objective To observe the radiological feature of chest X ray in SARS patients. Methods The chest films of 54 cases of SARS were reviewed in the study. The chest film features and site of lung involvement were studies in early stage, most severe stage and recovery stage. The correlation between the score of lung involvement and clinical course was also studied. Results 79.63% cases had abnormal chest films in early stage. Most of them (72.22%) were found in 3～7 days after onset. The lung involvement was most common in bilateral (88.89%) and most in middle and lower field (46.30%). Exudation and consolidation lesions showed to be dominant. The lesions progressed quickly and showed to be variable. There are 17 (31.48%) cases had second peak in X ray, the mean time of onset is 14.71 days. The chest X ray is not parallel with clinical syndrome. The absorption of lung infiltrates is correlation with glucocorticosteroids treatment in 20 patients, and the correlation is not found in 26 patients.Conclusions The chest X ray of SARS has some features and its changes can reflect the clinical situation.

Objective To analyze the 5-year survival rate,causes of death and prognostic indicators of systemic lupus erythematosus (SLE).Methods A retrospective analysis was performed on 243 newly diagnosed SLE patients who Were admitted into our hospital from 1998 to 2005.The clinical features and serologic data were studied.Survival rate of SLE patients over time was studied by the Kaplan-Meier method,and prognostic indicators of mortality were studied by Cox proportional hazards models.Results The 1-,3- and 5-yr survival rate was 96%,94% and 91%,respectively.Renal failure and infection were the main causes of death,followed by lupus encephalotmthy and pulmonary hypertension.Cox regression analysis revealed that lupus nephritis and lupus encephalopathy at the diagnosis were independent risk determinants for mortality.However,age,sex,low C3 level,positive anti-dsDNA antibody,hematological abnormalities,lupus lung involvement and heart damages at diagnosis and immunosuppressant treatment had no strong association with survival.Conclusion Early diagnosis,control of SLE organ damage and infection prevention are critical to improve survival of SLE patients.

Objective To compare the value of clinical application of the ratio of urine albumin to creatinine (ACR) in the community-dwelled middle-aged and elderly at high-risk for diabetes in screening for albuminuria with casual and morning urine specimens. Methods Totally, 443 middle-aged and elderly people (234 men and 209 women) at high-risk for diabetes, with an average age of (59±8) years, were recruited from Changfeng Community of Shanghai in screening for albuminuria with casual and morning urine specimens collected on the same day, as well as another two morning urine specimens collected at an interval of two weeks, for determination of urine ACR. Albuminuria was defined as ACR equal to or more than 30 mg (albumin)/g (creatinnine) in two or more of the three urine specimens collected. Results Overall prevalence of albuminuria was 6. 3% ( 28/443 ) in the middle-aged and elderly according to diagnostic standard mentioned above, significantly higher in casual urine specimens than in morning urine specimens (14. 9% vs. 5.9%, P <0. 05). Urine ACR of casual urine specimens was significantly higher than that of morning urine (7. 1 mg/g vs. 3. 2 mg/g, P<0. 001 ). There was no significant difference in sensitivity and positive predictive value (PPV) between casual and morning urine specimens in screening for albuminuria (96. 4% vs. 92. 9%, and 99.7% vs. 99. 5%, respectively, P >0. 05). Specificity and negative predictive value (NPV) of casual urine specimens was significantly lower than those of morning urine specimens (90.6% vs. 100.0%, and 40.9% vs. 100.0%, respectively, P<0.05). The optimal cut-off value of ACR by casual urine specimens was 40. 0 mg/g in screening for albuminuria, based on receiver operating characteristic (ROC) curve, with sensitivity of 96. 4%, specificity 95.2%, PPV 57.5% and NPV 99. 8%. The middle-aged and elderly with negative albuminuria in morning urine but positive in casual urine had more risk factors for cardiovascular and chronic kidney diseases than those with negative albuminuria in both morning and casual urine specimens. Conclusions Morning urine specimen is better than casual urine for albuminuria screening in the middle-aged and elderly people with risk factors for diabetes in urban community, but casual urine used in screening for albuminuria is very convenient for collection. It is suggested that urine ACR of 40. 0 mg/g be used as an optimal cut-off value for casual urine in albuminuria screening among them.

Objective: To explore the influence of awareness on the behaviors of Chinese adults with diabetes mellitus, so as to provide scientific evidence for developing relevant policies and strategies in the prevention and control of diabetes.Methods: Data from the 2013 China Chronic Disease Risk Factor Surveillance were used, covering 297 surveillance counties (districts).The variables involved in this cross-sectional study included: the prevalence of diabetes, the awareness situation, demographic characteristics, behaviors, and other information.The study used descriptive analysis to analyze diabetes status and chi-square test to determine the difference in the distribution of behaviors between patients who were aware of their disease and those who were not.Logistic analysis was performed to examine the influence of diabetes awareness on patients' behaviors with adjustment for potential confounders.Results: A total of 175 670 subjects were involved.The prevalence of self-reported diabetes in China in 2013 was 3.9%, while the awareness rate was 38.6%.The percentage of current smokers or current drinkers among the patients who were aware of their disease (20.2%, 25.0%) was less than that among the patients who were not aware (25.8%, 35.0%).The proportion of those who often exercised among the patients who were aware of their disease (83.4%) was higher than that among the patients who were not aware (79.0%).There was slightly higher proportion of the subjects who had insufficient intake of vegetables and fruits or over intake of red meat among the patients who were aware of their disease (49.4%, 28.0%) than that among the patients who were not aware (48.4%, 26.1%).After controlling urban and rural areas, regions, age, gender, nationality, marital status, educational level, occupation, and income factors, the possibility of current smoking (OR=0.79) or drinking (OR=0.58) among the patients who were aware of their disease was lower than among those who were not;the possibility of more than 150-minute physical activity per week (OR=1.30) among the patients who were aware of their disease was higher than among those who were not.Conclusion: The awareness rate of diabetes in China still remains low.Kno-wing whether they have diabetes or not has an effect on individual choice of behaviors, including smoking, drinking and physical activities.Therefore, health education and health examination for diabetes should be further expanded with wide cooperation from all relevant departments, thus forming an integrated environment involving individuals, health systems and socioeconomic policies to prevent and control diabetes.
