Exhaled breath condensate(EBC) analysis,as a new technology of studying the respiratory biochemical components in recent years,has the advantages of non-invasiveness,simple collection and good repeatability,etc.The detection of exhaled breath condensate biomarkers plays an important role in screening,early diagnosis,disease monitoring,efficacy and prognosis assessment,following up of lung cancer.

Objective To investigate the clinical characteristics and treatments of early-stage acute pancreatitis following laparoscopic cholecystectomy (LC). Methods From April 1998 to June 2006,totally 18 470 cases of LC were performed in our hospital,16 (0.09%) of them developed early-stage acute pancreatitis (

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.

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.

In July 2009, some farms of breeding Muscovy ducks on the peak of egg laying suffered the decrease of hatching rate and the quality of the eggs showing low mortality and no evident respiratory symptoms. The swelling and congestive ovary was visible after autopsy. This study was brought out for the diagnosis of these cases. The virus was isolated and identified by the methods of virus culture in chicken embryo, physical and chemical properties test, hemagglutinin test, NDV (Newcastle diseases Virus) interference test, electron microscope observation, pathogenicity test and the gene sequence analysis. The results indicated the virus showed the characters of inducing dwarf embryo after inocubation, the sensibility to lipid solvent and the hemagglutination capacity after pancreatic enzyme treatment, the typical morphology of coronavirus, the interference to NDV replication and the homology among 84.7% - 99% of the particial N gene sequences to the reference IBV (Avian infectious bronchitis virus) strains. The strain was identified as IBV isolate and this study confirmed the pathogenicity of IBV to Muscovy ducks.

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.

Aim To investigate the effect of Ding''s herb enema prescription on intestinal tissue related target in rat colitis induced by dextran sulfate sodium(DSS), and to elucidate the mechanism of Ding''s herb enema prescription in improving the intestinal inflammation and intestinal fibrosis.Methods Rats were fed with 3.5％ DSS.The rats were randomly divided into positive drug group, model group, Control group, and Ding''s herb enema prescription group.The positive drug group was treated with mesalazine enema, and Ding''s herb enema prescription group was treated with Ding''s herb enema prescription.The colon mucosa was taken once a day for 6 weeks.The changes of intestinal inflammatory response and intestinal fibrosis related proteins were detected by GSR-CAA-67 antibody protein array, and the differentially expressed proteins were screened out.Results Eight proteins showed statistical differences, including IFN-γ, erythropoietin(EPO), TIMP-2, TIM-1, IL-6, TIMP-1, TNF-α, IL-22 (P<0.05).On the other hand, Ding''s herb enema prescription and mesalazine significantly antagonized the effect of IL-6 and TIMP-1 (P<0.05).The antagonized effect of Ding''s embolization enema on TNF-α and IL-22 was also significant(P<0.05), but mesalazine had no similar effect (P>0.05).Conclusions Ding''s herb enema prescription has the effect of multiple targets, which may improve the intestinal inflammatory response and intestinal fibrosis to achieve the purpose of treatment of ulcerative colitis(UC).

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.
