ABSTRACT
PURPOSE: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients.METHODS: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed.RESULTS: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%).CONCLUSIONS: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.

Objective To understand the seasonal distribution of patient hospitalization due to asthma exacerbation in 7 geographic areas in China.Methods This was a retrospective study which involved patients hospitalized for asthma exacerbation in 29 hospitals throughout 7 geographic areas in the mainland of China (northeast,north,central,east,south,northwest and southwest).The numbers of asthmatic patients and total inpatients of the respiratory department of each hospital were recorded.The monthly ratio of asthmatic patients to the total inpatients in every area was calculated and compared.Results During the study period,6 480 patients were admitted for asthma exacerbation,accounting for 3.14％ of all the 206 135 patients admitted to the respiratory departments in the 29 hospitals.The ratio of asthmatic patients to total inpatients in the northeast area (5.61％) was highest,and the ratio in east area was lowest (1.97％).Statistical analysis showed that the difference among different areas was significant (P＜0.000 1).In most areas,both the number and proportion of hospitalized asthmatic patients peaked in spring (February-April) and autumn (September-October).In the northeast area,east area and south area,the peaks in spring were more obvious,while in the north area and southwest area,the peaks in autumn were more obvious.In the northwest area the peaks occurred in winter (December-January) and summer (June-August),respectively.The differences in hospitalization due to asthma among different months were significant in the northeast,north,and southwest areas (P＜0.005).Conclusion The number of patients hospitalized for asthma exacerbation fluctuated with season in different areas in China.In most areas,more asthmatic patients were admitted to hospitals in spring and autumn.

ABSTRACT
Objective The expression of TNF-α was detected in sera of rabbits treated by ulinastatin with acute lung injury in duced by underwater explosion.Methods Rabbits were randomly divided into two groups such as the injured group and ulinastatin therapy group.Established underwater explosion device was used to cause acute lung injury in rabbits.TNF-α in sera of the rabbits were measured by ELISA at 4,12 and 24 hours after the explosion.The SPSS17.0 software was used to analyze the data and P＜0.05 was considered to be significant.Results There was no significant difference between the concentrations of TNF-α in the sera of rabbits in the injure group (538.20±201.43 ng/L) and that of in the ulinastatin group (386.90± 109.22 ng/L,t=2.088,P=0.051) at 4 hours after burst.However,there was evidently decreased in the level of TNF-α in the ulinastatin group (400.60 ± 78.98 ng/L) compared with the injury group (573.80 ± 178.24 ng/L,t =2.809,P =0.012) at 12 hours after burst.Moreover and TNF-α in the ulinastatin group (356.10 ± 130.99 ng/L) was also decreased compared to the injure group (552.30± 169.64 ng/L,t=2.895,P=0.010) at 24 hours after burst.Conclusion The TNF-α expression in sera of the rabbits in ulinastatin group were dramatically decreased than thai of in injury group at 12 hours after burst,which may be benefit to rabbits with acute lung injury induced by underwater explosion.
ABSTRACT
Objective To discuss the treatment method and opportunity for patients with gallbladder stones and extrahepatic bile duct stones who failed endoscopic removal of common bile duct stones by endoscopic retrograde cholangiopancreaticography (ERCP). Methods 12 patients, with gallbladder stones and extrahepatic bile duct stones, failed endoscopic stone extraction (ESE), underwent emergency one-stage laparoscopic cholecystectomy (LC) and Laparoscopic common bile duct exploration (LCBDE). Results All of the patients were successfully completed LC +LCBDE and stones were completely removed. Hyperamylasemia occurred in 3 cases and there was no bile leakage, intestinal leakage, cholangitis, pancreatitis, biliary bleeding and other complications. Conclusions Emergency LCBDE has been shown to be a safe and effective salvage procedure for failed ESE.
ABSTRACT
Objective To investigate the clinical value and safety of thoracoscopic lung biopsy in the diagnosis of diffuse parenchymal lung diseases. Methods 35 patients with diffuse parenchymal lung disease underwent thoraco-scopic lung biopsy were reviewed in order to obtain clinical and pathological data. Results 31 cases were diagnosed by pathology, and the total positive diagnostic rate was 88.6 % (31/35), 10 cases as usual interstitial pneumonial (UIP), 6 cases as Tuberculosis, 4 cases as alveolar cell carcinoma, 3 cases as nonspecific interstitial pneumonia (NSIP), 3 cases as crypto-genieorganizingpneumonia (COP), 2 cases as pulmonary alveolar proteinosis (PAP), 1 case as Wegener's granulomatosis (WG), 1 case as acute interstitial pneumonia (AIP), 1 case as lymphangioleiomyomatosis (LAM). 3 cases (8.6 %) were occurred with postoperative complications, 2 cases as pulmonary infection combined with respiratory failure, 1 case as idiopathic pulmonary fibrosis with acute exacerbation, and 2 cases (5.7 %) were complicated with death. Conclusions Thoracoscopic lung biopsy is a safe and effective method which helps final di-agnosis of diffuse parenchymal lung disease.
