Objective To evaluate the role of CCAAT/enhancer-binding protein homologous protein (CHOP) in ischemia-reperfusion induced lung injury, and clarify the potential molecular mechanism.Methods Fifty mice of C57BL/6J were randomly divided into five groups, 10 mice in each group, including Sham operation group(sham group),ischemia/reperfusion group (I/R group), I/R +PBS+Lipofectamine group(I/R+PBS+Lipo group) , I/R+scramble siRNA group( I/R+siRNASCR group) , I/R+CHOPsiRNA group( I/R+siRNACHOP group).The content of total lung water (TLW), wet-to-dry weight ratio (W/D) of lung and index of quantitative assessment of histologic lung injury (IQA) were detected, CHOP mRNA and protein expression were detected by RT-PCR and Western blot.Results Compared with Sham group, W/D, TLW and IQA were significantly elevated in I/R group,I/R+PBS+Lipo group and I/R+siRNASCR group (P<0.05).Moreover, the W/D,TLW and IQA reduced with CHOP-siRNA treatment, respectively(P<0.01).Compared with Sham group, CHOP mRNA and protein expressions were significantly elevated in I/R group,I/R+PBS+Lipo group and I/R+siRNASCR group, Moreover, the CHOP mRNA and protein expressions reduced with CHOP-siRNA treatment, respectively(P<0.01). Conclusion I/R could cause excessive unfolded protein response in lung tissue, and induce apoptosis by CHOP signal pathway, damage lung tissue. The inhibition of CHOP pathway could alleviate lung ischemia-reperfusion injury.

Gallibacterium anatis,a member of the Pasteurellaceae family,constitutes a part of the normal micro-flora of the upper respiratory tract and the lower genital tract in chickens.However,increasing evidence indicate that G.anatis is also associated with a wide range of pathological changes,particularly in the reproductive organs,which leads to decreased egg production,lowered animal welfare and increased mortality.As a recently defined opportunistic pathogen limited focus has been placed on the pathogenesis and putative virulence factors permitting G.anatis to cause disease.One of the most studied virulence determinants is a large RTX-like toxin (GtxA),which has been demonstrated to induce a strong leukotoxic effect on avian macrophages.A number of fimbria of different sizes and shapes,particularly the F17-1ike fimbriaes,appear to be common in a diverse selection of G.anatis strains.The capsular material expressed possibly involved in serum resistance,metalloproteases capable of degrading immunoglobulins,hemagglutinins,and all factors which may promote biofilm formation are likely linked to the virulence of G.anatis.This review summarized the putative virulence factors described for this bacterium to date.

Background During the past two decades, a number of rating scales were developed to facilitate diagnosis and assessment of subjects with social anxiety disorder. One of the most commonly used scales for the assessment of social anxiety disorder is the Liebowitz social anxiety scale (LSAS). The LSAS is widely used in epidemiologic investigations and clinical researches,and its assessment in the pharmacotherapy efficacy for social anxiety disorder is superior to any other scale. So we designed this study to explore the validity and reliability of the LSAS in Chinese patients with social anxiety disorder and normal control, and to find the difference of the scores between the patients self -report version and clinician-administered version. Methods Fifty five patients meeting the DSM-Ⅳ diagnostic criteria for social anxiety disorder and 168 normal controls who were screened from 222 college students were rated by LSAS, social phobia scale and self-made General Information Forms. Results The Cronbath α of LSAS for the patients and the normal controls was 0.83 and 0.77, respectively. The 4-week test-retest reliability for total scores and its factors scores of LSAS in 31 normal controls were ranging from 0.68 to 0.79. The ROC area under curve value in discriminating the patients from normal controls was 0.87±0.03; the total score of 35 was considered to be the best cut-off score for LSAS, then its sensitivity was 0.77 and its specificity was 0.81; and no significant difference between the self-report version and clinician-administered version. Conclusions The LSAS is good in internal consistency and test-retest reliability, and has high sensitivity and specificity in discriminating the patients and the controls. There is no significant difference in the total score and each factor scores of LSAS between self-report version and clinician-administered version.

Objective: To explore the peri-operative treatment and 3 years post-operative outcome in patients with rheumatic mitral valve stenosis and small left ventricle. Methods: A total of 152 patients with rheumatic mitral valve stenosis and severe pulmonary hypertension were studied. According to left ventricular end diastolic index (LVEDI) value, the patients were divided into 2 groups: Small left ventricle (Small) group, the patients with LVEDI value≤60 mm, n=67 and Non-small left ventricle (Non-small) group, the patients with LVEDI value>60 mm,n=85. Peri-operative condition and follow-up parameters were compared between 2 groups. Results: Compared with Non-small group, Small group had increased pre-operative CVP, SPAP and decreased LVEDV, LVEDVI and RVEF at admission, all P<0.05. All patients had liver damage at admission, the indexes (except alkaline phosphatase) were higher in Small group than Non-small group, and the function was recovered prior operation by proper treatment. The immediate post-operative SPAP in Small group and Non-small group were (67.3.1±23.4) mmHg and (61.3±26.9) mmHg, P>0.05. There were 52 severe pulmonary hypertension patients received iloprost inhalation, their SPAP was decreased than non-inhalation patients at incision closing; SPAP was lower in Small group inhalation patients than Non-small group inhalation patients, all P<0.05. Post-operative LVEDVI was lower and SPAP was higher in Small group than Non-small group. At 3 years post-operation, LVEDVI, RVEF increased, NYHA classification decreased and 6MWT prolonged in both groups; while LVEDVI was lower and 6MWT was shorter in Small group than Non-small group, P<0.05. The median survival time at (3.7±1.6) years post-operation was shorter in Small group than Non-small group,P<0.05, while the mortality was similar between 2 groups (2.6% vs 2.0%),P>0.05. Conclusion: The patients with mitral valve stenosis and small left ventricle had the worse pre-operative condition and higher risk in surgery; peri-operative treatment could improve their cardiac and liver function, but they still had the shorter post-operative median survival time.
