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 explore effect of objective life status and psychological factors on the life satisfaction (SLS) in retired carders.Methods:Two hundred and forty-four retired carders were assessed with Quality of Life Inventory (QOLI), The Elderly's Coping Style Questionaire and Social Support Questionaire.Results:The correlation analysis showed that SLS was significantly related with OIQL, coping style, social support,and life expectation.Multiple stepwise regression analysis revealed that objective indicators about physical state and mental state from OIQL distancing style from positive coping and social support had significant effect on SLS.

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 study the relationship between NO, NOS and TNF-? of serum and surgical infection. Methods: We used chemistry technique and ELISA to study serum NO, NOS and TNF-? in 30 cases of surgical infection.Results: Compared with normal group and before treatment group NO, NOS and TNF-? were singnificantly higher in surgical infection(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.

Objective To investigate the effects of acupuncture at points Baihui (GV20), Yintang (Ex-HN3) and Sishencong (Ex-HN1) on spatial learning and memory abilities and hippocampal expression of brain-derived neurotrophic factor (BDNF) in a rat model of post-stroke depression (PSD). Method Thirty male adult SD rats were allocated, using a random number table, tocontrol, acupuncture and sham operation groups, 10 rats each. A rat model of PSD was made by classical middle cerebral artery occlusion (MCAO) using an intraluminal thread technique, chronic unpredictable mild stress (CUMS) and solitary feeding. At the fourteenth day after the beginning of stress, the acupuncture group received acupuncture intervention for 14 consecutive days. At one week after the end of stress, the Morris water maze test was conducted to assess rat spatial learning and memory abilities. After the completion of the water maze test, hippocampal CA3 regional BDNF expression was determined by immunohistochemical method. Result Rat learning and memory abilities decreased significantly in the control group compared with the sham operation group (P<0.05). Space exploration time and the number of crossing platform reflecting memory abilities decreased significantly in the control group (22.36±6.20 s and 3.72±0.90 times, respectively) compared with the sham operation group (48.73±5.40 s and 8.60±1.10 times, respectively); there were statistically significant differences (P<0.01). Learning abilities, space exploration time, the number of crossing platform and BDNF expression increased significantly in PSD rats treated with acupuncture compared with the control group; there were statistically significant differences (P<0.01). Conclusion Acupuncture can improve spatial learning and memory abilities and raise hippocampal regional BDNF levels in rats with post-stroke depression.

Objective To study the early and mid-term outcome in terms of left ventricular(LV)geometry and function in patients with transposition of great arteries with intact ventricular septum (TGA/IVS) undergoing arterial switch operation.Methods Twenty patients were followed up and divided into 2 groups according to age:the earlier group and the later group.Age and sexual matched controls were also designed as control group 1 and control group 2.LV posterior wall thickness(PWTd),dimension(LVIDd)and length(L) at end diastolic phase,LV end-diastolic volume (EDV),end-systolic volume (ESV),ejection fraction (EF),mitral valve early (E) and late (A) inflow velocities and E/A,isovolumic relaxation time (IVRT) were obtained by two-dimensional echocardiography,normalized isovolumic relaxation time (IVRTn),wall thickness index (PWTd/LVIDd) and LV geometry index(LVIDd/L) were calculated,and these indexes between groups were compared.Results ①Compared with control group 1,PWTd in earlier group was higher [(0.41 + 0.06)cm vs (0.36 + 0.05)cm,P =0.022],but LVIDd had no significant statistical difference [(2.08 + 0.21)cm vs (2.21 + 0.23)cm,P =0.117],indicating PWTd/ LVIDd differed between groups(0.20 + 0.04 vs 0.16 + 0.01 P =0.001).②No abnormalities were observed in later group.③Compared with different age groups in TGA,EDV,ESV,L,LVIDd,PWTd were significantly higher in later group(P =0.000).There were obvious correlations between EDV,ESV,L,LVIDd and examined age (r =0.90,0.83,0.73,0.90,P =0.000,R2 =0.809,0.694,0.528,0.808) while there were no significant correlation between PWTd and examined age(r =0.56,P =0.000,R2 =0.309).Conclusions Early after operation,LV is undergoing hypertrophy or hyperplasia in TGA/IVS,but will recover in the mid-term period,and the function is normal all the time indicating that the LV myocardium may avoided irreversible pathological changes if operated in time.All in all,LV develops well in mid-term period.
