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.

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.

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 investigate the pathogen distribution and drug resistance of gram-negative bacteria causing lower respiratory tract infections in patients with acute exacerbation of chronic obstructive pulmonary disease ( AECOPD) .Methods A total of 742 sputum samples were collected from AECOPD patients with lower respiratory tract infections in Taizhou Hospital of Zhejiang Province during January 2013 and December 2014.Vitek 2 Compact system combined with disk diffusion was used for strains identification and drug susceptibility test.Modified Hodge test and ethylenediamine tetraacetic acid (EDTA) synergic test were used to screen carbapenem-resistant strains.Statistical analysis was performed using WHONET 5.6 and SPSS 20.0 software.Results A total of 593 strains of gram-negative bacteria were isolated , in which 367 strains were nonfermentative bacteria (61.89%), 220 strains were enterobacteriaceae (37.10%), and the rest 6 strains ( 1.01%) were other gram-negative bacteria.Acinetobacter baumannii ( 186 strains ), Pseudomonas aeruginosa (99 strains), Stenotrophomonas maltophilia (33 strains) and Burkholderia cepacia (22 strains ) were top 4 nonfermentative bacteria , and they all showed high resistance to ampicillin , ampicillin/sulbactam, cefazolin, ceftriaxone, cefotetan and nitrofurantoin with resistant rates of 67.20%-100.00%. Drug resistance rates to other β-lactams, fluoroquinolones, aminoglycoside, compound sulfamethoxazole and minocycline were significantly higher in carbapenem-resistant Acinetobacter baumannii and Pseudomonas aeruginosa strains than those in non-carbapenem-resistant strains , and the differences were statistically significant (P <0.05 or <0.01).Stenotrophomonas maltophilia and Burkholderia cepacia strains were only sensitive to levofloxacin , compound sulfamethoxazole and minocycline . Klebsiella pneumonia (89 strains), Escherichia coli (80 strains) and Enterobacter cloacae (25 strains) were top 3 enterobacteriaceae , which were almost completely resistant to ampicillin , but were sensitive to piperacillin/tazobactam , cefoperazone/sulbactam , amikacin and carbapenems ( with resistant rates <15%) .More than 50%strains of extended spectrum β-lactamases ( ESBLs )-producing Klebsiella pneumonia and Escherichia coli were moderately or highly resistant to ampicillin/sulbactam , most cephalosporins ( except cefotetan and cefoperazone/sulbactam ), gentamycin, tobramycin, fluoroquinolones, aztreonam, compound sulfamethoxazole and minocycline , and the resistant rates were higher than those in non-ESBLs-producing strains (P <0.05 or <0.01).Conclusions Nonfermentative bacteria and enterobacteriaceae are the most prevalent gram-negative bacterial pathogens in lower respiratory tract infections in patients with AECOPD . Carbapenem-resistant Acinetobacter baumannii and Pseudomonas aeruginosa strains, as well as ESBLs-producing Klebsiella pneumonia and Escherichia coli strains are highly resistant to most antibacterial agents .

Treatment resistant depression is a common and severe mental disorder associated with significant burden of disease .Most individuals receiving conventional pharmacotheraphy fail to achieve and sustain remission.So this is still one of the difficult challenges for the psychiatrist .Much of the research pro-vided indications that the efficacy of treatment for the disease was not optimistic, but the treatment was still made great progress .The common treatments for this disease included pharmacotherapy,psychotherapy,elec-troconvulsive therapy(ECT),transcranial magnetic stimulation (TMS),magnetic resonance guided focused ultrasound surgery( MRgFUS) ,deep brain stimulation ( DBS) ,aerobic exercise,light therapy and so on.Each therapeutic strategy has its own features, and could be suitable or unsuitable in some situations.The high rates of non-remission with first-line treatment strategies make the combination of antidepressant and non-drug treatments to be the new trend of the treatments for treatment resistant depression in the future.
