Objective To describe the characteristics of pulmonary involvement in Crohn was described and relevant literature were reviewed. Results The patient showed chief complaints of cough,expectoration and fever. The chest CT scan revealed bilateral lung opacity shadows ,Ziehl-Neelsen acid-fast stain examination in sputum and cultures got negative results for many times. Chest CT scan revealed no dissipation after different antimicrobials treatment for 2 months. The fiberoptic bronchoscopy was performed, which showed nodular lesions in the trachea and beside the opening of right upper lobe. Histopathology showed polypoid hyperplasia of granulation tissue. The bilateral patchy opacity dissipated, the nodes in the trachea disappeared and the nodes beside the opening of right upper lobe diminished obviously after the patient was treated with oral prednisone and salicylazosulfapyridine (SASP). Pulmonary involvement in Crohn disease is very rare and it can involve any part of the lungs. The most common manifestations are cough, expectoration and fever. The lung and gastrointestinal system often share similar pathogenetic changes: granulomatous inflammation. These patients responded well to combination use of glucocorticoid and SASP. Conclusion Pulmonary involvement should be considered when patients with Crohn disease manifested with respiratory symptoms, which can be definitely diagnosed by clinical features and histopathological examintation.

Objective To investigate the expression of survivin and bcl-xl in non-small cell lung cancer(NSCLC)and their relationship.Methods The NSCLC tissuechips including 32 cores were constructed and expression of survivin and bcl-xl was examined by immunohistochemical technique in 30 normal bronchial epithelium and 32 primary NSCLC.Results The positive rate of survivin and bcl-xl protein in NSCLC was 71.9% and 81.3% respectively,significantly higher than that in the normal ones(P0.05).The expression of bcl-xl protein was closely related to cell differentiation(P0.05).The over-expression of survivin and bcl-xl was positively correlated(P

Objective To evaluate the effect of gastroesophageal reflux disease(GERD)on exacerbations of chronic obstructive pulmonary disease(COPD).Methods All of 74 patients with COPD accomplishing the reflux diagnostic questionnaire(RDQ)were.divided into GERD group(n=38)and non-GERD group(n=36)according the scores of RDQ.The clinical data including the frequency of exacerbations of COPD were compared between the two groups.Results The frequency of exacerbations of COPD was significantly higher in GERD group compared with that in non-GERD group[(2.68±0.77)times/year vs (1.38±0.49)times/year,t=8.74,P＜0.05].The mean FEV;percentage was similar in the two groups [(39.82 4-10.95)%vs(37.11±12.24)%,t=1.00,P＞0.05].The score of RDQ was probably as a factor of predicting the frequency of exacerbations of COPD(R2a=o.39,t=6.98,P＜0.05).Conclusion The presence of GERD appears to be associated with increased exacerbations of COPD.

A total of 59 untreated asthmatics and 47 healthy control subjects were recruited from Qianfoshan Hospital of Shandong Province from May 2011 to April 2012.Compared with healthy control subjects,the levels of IL-25 in induced sputum and eosinophils,IgE,interleukin-4 (IL-4) and interleukin25 (IL-25) in serum samples of asthmatics were significantly higher while the level of interferon-gamma (IFN-γ) were much lower.However,after inhaled glucocorticoid treatment,the levels of eosinophils,IL-4 and IL-25 decreased and IFN-γ significantly increased,while the level of IgE showed no significant changes.It was also found the expression of IL-25 was markedly positively correlated with the levels of eosinophils and IL-4 in serum and markedly negatively correlated with the levels of IFN-γ and had no relatio.
