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 investigate effect of Qishen-Qinggan decoction on proliferation and apoptosis of human hepatocellular carcinoma cellline SMMC-7721.Methods SMMC-7721 cells were cultivated in vitro.Logarithmic growth phase cells were divided into a drug intervention group and a control group.SMMC-7721 cells were treated with Qishen-Qinggan decoction of 0.135、0.27、0.54、1.08、2.16 g/ml respectively for 12、24、48 hours in the drug intervention group while the control group remained untreated.The inhibition rate of SMMC-7721 cells were detected by MTT assay,cell apoptotic rate were measured by flow cytometry analysis.Results Qishen-Qinggan decoction of 0.135,0.27,0.54,1.08,2.16 g/ml had a significantly inhibitory effect on SMMC-7721 cells in a dose and time dependent manner.OD values of 12 hours were 0.89±0.05,0.85±0.05,0.80±0.06,0.78± 0.02,0.69±0.07,OD values of 24 hours were 0.77±0.07,0.74±0.07,0.59±0.07,0.50±0.09,0.39±0.08,OD values of 48 hours were 0.78±0.05,0.61±0.08,0.44±0.10,0.39±0.08,0.34±0.07 respectively.Each drug intervention group had significant difference compared with control group.Qishen-Qinggan decoction of 0.27,0.54 g/ml could induce apoptosis of SMMC-7721 were 11.19 ± 2.23,15.69 ± 2.51,compared with control group of 1.41 ± 0.22.Apoptotic rates of Qishen-Qinggan decoction of 1.08 g/ml had extremely significant difference with the control group (41.83 ± 7.11 vs 1.41 ± 0.22).Conclusion Qishen-Qinggan decoction could inhibit the proliferation of SMMC-7721 cells probably by inducing cell apoptosis.

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.

Objective To evaluate the clinical application value of CT angiography(CTA) in detection of the accessory renal artery(ARA).Methods The renal artery CTA in 100 cases was reconstructed retrospectively with volume rendering (VR), multiplanar reconstruction (MPR), maximum density projection (MIP) and curved surface reconstruction (CPR).Results In all 200 kidneys,ARA were 47 with an incidence of 23.5% (47/200).The incidence of ARA in male and female were about 17% and 13%, and there was no significant difference between them.The ARA in the upper pole of the kidney was 25 (53.1%), and in lower pole was 22 (46.9%).It was showed on MIP with a display rate of 100%, on MRP of 93.6%, on VR of 90.4% and on CPR of 85.1%.Conclusion CTA is a safe, rapid, noninvasive and economical method for the diagnosis of ARA.It is helpful for surgical renal operation, interventional therapy and renal transplantation.
