Objective　To investigate the mechanisms of Pinacidil prec onditioning protection of hemorrhagic shock rats. 　Methods　The rats were divided into 3 groups: a normal group ( n=10), a control group (n=40) and a preconditioning group (n=40). Pinacidil preconditio ning was processed 24 h before making the hemorrhagic shock model. The cPLA 2 expression in myocardium was observed at different time points with western blot; Pinacidil preconditioning was processed 24, 48 and 72 h before making th e hemorrhagic shock model to observe hsp70 expression in myocardium and liver tissue with western blot. 　Results　Pinacidil preconditioning could increase hsp70 expres sion and decrease cPLA2 expression. 　Conclusions　Pinacidil preconditioning protects "shock cell" by inducing hsp70 overexpression and inhibiting cPLA2 expression, which is re sponsible for protecting myocardial and liver tissues of the hemorrhagic shock rats.

OBJECTIVE:To observe the clinical short-term efficacy and safety of brucea javanica oil injection combined with oxaliplatin and xeloda in the treatment of elderly patients with advanced gastric cancer. METHODS:82 elderly patients with ad-vanced gastric cancer were randomly divided into control group and observation group. Control group was treated with Oxaliplatin injection 130 mg/m2 added into 5% Glucose injection 250 ml for 2 h,iv,d1+Xeloda tablets 1 000 mg/m2,orally,twice a day, d1-14;based on the treatment of control group,observation group was additionally treated with 10% Brucea javanica oil injection 30 ml added into 0.9% Sodium chloride injection 250 ml,iv,once a day,d1-14. 21 days were as a treatment course,and it lasted 3 courses. The short-term efficacy,life quality and toxicity reactions were evaluated in 2 groups. RESULTS:The short-term efficacy in observation group was significantly higher than control group,life quality was significantly better than control group,and the in-cidences of leucopenia and liver damage were significantly lower than control group(P<0.05). CONCLUSIONS:Brucea javanica oil injection combined with oxaliplatin and xeloda has better efficacy than oxaliplatin combined with xeloda in the treatment of elder-ly patients with advanced gastric cancer,with good safety.

Hemicellulose is a kind of very abundant carbohydrate,which is not y ot exploited Arabinofuranosidase is important enzyme in biodegradation of hemi cellulose Up to now many arabinofuranosidases and genes have been studied in t he world In this paper, we reviewed mainly on the classification, characterizati on, utility and gene expression of arabinofuranosidase

Objective To evaluate the diagnostic value of multi-slice spiral CT(MSCT)perfusion imaging in chronic obstructive pulmonary disease(COPD).Methods Twenty COPD patients and20 volunteers underwent 8-row detector spiral CT(MSCT)perfusion imaging using cine scan mode with5 mm slice thickness.0.5 s rotation time and a total scan time of 45 s with 5 s intervals.60 ml contrast agent(300 mg I/ml)were administered at a rate of 4 ml/s from the forearm superficial vein.The imaging data were transferred to a workstation.A time-density curve and pseudo-color map were generated automatically with GE CT perfusion 3 software,the blood flow(BF),blood volume(BV),mean transit time(MTr)and permeability surface(PS)were measured.Results Time-density curve was flatter and the peak of the curve was obviously lower in COPD patients than the volunteers.The BF.BV.PS in COPD volunteers was(10.58 ±4.85)s and(4.50 ±1.71)s respectively.The BF,BV and PS in COPD patients Was lower than the volunteers,the MTY was higher(P＜0.01).Conclusion MSCT perfusion imaging is helpful for the diagnosis of COPD.

Objective Little is known about the effects of antioxidant on the micturition function in diabetic cystopathy .In this study, we investigated the effects of antioxidant sulforaphane on bladder micturition function in diabetes mellitus ( DM)mice with bladder underactivity . Met hods We established DM models in mice by intraperitoneal injection of a single dose of streptozotocin (STZ)at 65 mg/kg and randomly divided them into three groups , sulforaphane treatment (n=10), vehicle treatment (n=10), and DM model (n=10), with another 10 normal healthy mice included as blank controls.At 24 weeks of the experiment, we obtained and analyzed such indexes of mice as the body weight , fasting blood glucose (FBG), 24-hour urine volume (24 h UV) and bladder wet weight ( BWW ) , results of cystometrography , and cystometric parameters including intercontraction interval ( ICI ) , maximum bladder pressure during micturition ( Pmax ) , maximum cystometric capacity (MCC), void volume (VV), post-void residual urine vol-ume (PVR) and residual urine rate (RUR). Results Compared with the blank controls , the DM models with bladder underactivity showed significantly increases in BWW ([67.96 ±2.35]mg), 24 h HU ([22.47 ±1.93]mL), MCC ([0.70 ±0.03]mL), VV (0[.23 ±0.01]mL), PVR ([0.49 ±0.02]mL), RUR ([70.10 ± 0.80]%), and ICI, but a remarkable decrease in Pmax .Sulforaphane treatment significantly reduced BWW ([576.9 ±2.41]mg), 24 h HU ([16.27 ±1.51] mL), MCC ([0.54 ±0.03]mL), PVR ([0.34 ±0.02]mL), RUR ([62.71 ±1.26]%), and ICI of the diabetic mice . Conclusion Sulforaphane could improve bladder micturition function in mice with STZ-induced DM , which might be related to its action mechanism of antioxidative stress damage .

OBJECTIVE To determine the sensitivity of Vibrio vulnificus to 23 kinds of antibacterial drugs,and offer the evidence for clinical V.vulnificus infections treatment.METHODS Isolated 11 strains of V.vulnificus from the patients blood and blisters of infected parts,using ATB automatic identification and susceptibility testing to measure the vitro drug sensitivity of the bacteria.RESULTS The susceptibility of the bacteria to the 22 kinds of commonly used antibiotics showed 100% sensitivity,the rate of ciprofloxacin sensitivity was 72%.CONCLUSIONS It is sensitive to commonly used semi-synthetic penicillin,cephalomycin,carbapenem,aminoglycosides,the third generation cephalosporins,fluoroquinolones and so on,all these above drugs may be chosen to treat the V.vulnificus infection.
