Ankylosing spondylitis (AS) is a systemic disease, which mainly causes to axial joint chronic inflammation. Spine, thoracic and peripheral joints may have varying degrees of activity limitation, and somatic activity is also likely to decline. Ankylosis of the spine and movement disorder of hip are the mainly causes of AS patients' disability, which not only affect the patients' motor function, and but also affect their social interaction, role affordability, mental state and daily living skills. Exercise therapy is the treatment unarmed or with equipment, for injuries, disease, residual patients, to restore or improve dysfunction. There are a number of studies about exercise therapy for joint function of patients with AS, confirmed that exercise therapy plays a crucial role in the treatment of AS patients, on the basis of the medications control.

Objective To explore the related neurobiochemical mechanism by comparing the concentration change of dopamine (DA),dihydroxy-phenyl acetic acid (DOPAC),glutamate (Glu),and γ-aminobutyric acid (GABA) in the brain tissues in schizophrenia (SZ) developmental model rats and chronic medication model rats.Methods A total of 60 neonatal male Spragur-Dawley (SD) rats were randomly assigned to 3 groups at the postnatal day 6:an SZ developmental rat model group (subcutaneous injection with MK-801 at the postnatal day 7-10,0.1 mg/kg,Bid),a chronic medication model group (intraperitoneal injection at the postnatal day 47-60,0.2 mg/kg,Qd),and a normal control group (injection with O.9％ normal saline during the corresponding periods).DA,DOPAC,Glu,and GABA of the tissue homogenate from the medial prefrontal cortex (mPFC) and hippocampus were examined with Coularray electrochemic detection by high performance liquid chromatogram technique.The utilization rate of DA and Glu was calculated.Results Compared with the normal control group,the concentration of DA and DOPAC in the mPFC and the hippocampus in the SZ developmental model group significantly decreased ( P ＜ 0.05 ),and the GABA concentration and Glu utilization rate in the mPFC also decreased (P ＜ 0.05 ).Compared with the chronic medication model group,the DA concentration of the mPFC in the SZ developmental group decreased ( P ＜ 0.05 ),and the DOPAC concentration and the utility rate of DA in the hippocampus also decreased (P ＜0.01,P ＜0.05,respectively).Conclusion The activities of DA,Glu and GABA system decrease in the mPFC and the DA system function reduces in the hippocampus of SZ developmental rats.

Objective To establish the in vitro biofilm model of Laribacter hongkongensis(LH),to analyze the type Ⅰ integron related genes carried by LH and to investigate the mechanism of LH resistance to quinolones.Methods The biofilm forming abilities of LH clinical isolates were determined by Giemsa staining qualitative method and by crystal violet staining semi-quantitative method.The sensitivity of LH to norfloxacin,ofloxacin,levofloxacin,ciprofloxacin and lomefloxacin in both planktonic and biofilm conditions were dectermined by broth microdilution susceptibility tests.Type I integron related genes carried in 18 LH strains resistant to quinolone were detected by PCR amplification method.Results The detection results by Giemsa staining demonstrated that 36 strains in 55 LH clinical isolates formed visible biofilm,and the biofilm formation rate was 65.4%(36/55).In the biofilm forming ability detected by crystal violet staining semi-quantitative method,OD560≤0.15 was in 8 strains of LH,0.150.20 in 7 strains respectively.The levels of minimal biofilm inhibitory concentration in norfloxacin,ofloxacin,levofloxacin,ciprofloxacin and lomefloxacin to LH were respectively higher than the minimal inhibitory concentration(MIC) in the corresponding floating bacteria(P<0.05).Among 55 strains of LH,18 strains were resistant to quinolones,the resistance rate was 32.7%,and the type I integron in 18 strains of LH carried the drug resistant genes,these drug resistant genes played the drug resistance role in corresponding bacterial strains.Conclusion Drug resistance gene formation and widespread of LH may be associated with type I integron.
