0. 05). Conclusion The expression of VEGF is highly related to the invasion, DNA ploidy and cellular proliferation activity of malignant bone tumor. It isn't related to the size of tumor. The expression of VEGF is probablya predictor for judgment of malignant degree of bone tumor.

Objective: The study was designed to observe the effects of alanyl-glutamine (Aln-Gln) dipeptide on postoperative intestinal permeability and stress response. Methods: A prospective, randomized and controlled trial was taken. 20 patients who underwent abdominal surgery were randomized into two groups: study group [intravenous administration of Aln-Gln dipeptide, 0.5 g/(kg?d), for 4 days, n=10 and control group (normal saline as placebo, for 4 days, n=10)]. Serum concentrations of glutamine (Gln), diamine oxidase (DAO), cortisol, interleukin-6(IL-6) and urine lactulose/mannito (L/M) ratio were measured before and after operation. Results: Serum Gln concentration was significantly decreased in control group and increased in study group on postoperative day 5.Urine L/M ratio was significantly increased in control group and decreased in study group.The serum concentrations of DAO,cortisol and IL-6 were significantly decreased in study group while compared with control group. Conclusion: Administration of Aln-Gln dipeptide can increase the level of serum Gln,decrease the intestinal permeability and attenuate the stress response in the early period of postoperative patients. Aln-Gln dipeptide can be used in the fast track surgery.

Objective: The study was designed to observe the effects of alanyl-glutamine(Aln-Gln) dipeptide on postoperative intestinal permeability and immmunologic function in abdominal patients. Methods: A prospective,randomized and controlled trial was taken.20 patients who underwent abdominal operation were divided into two groups: study group(intravenous administration of Aln-Gln dipeptide,0.5 g/(kg?d),for 4 days,n =10) and control group(equal normal saline as placebo,for 4 days,n =10).Serum concentrations of glutamine(Gln) and diamine oxidase(DAO),blood total lymphocyte count(TLC) and human leukocyte antigen(HLA)-DR and urine lactulose/mannito(L/M) ratio were measured before and after operation. Results: Serum Gln concentration was significantly decreased in control group and increased in study group on postoperative day 5.Urine L/M ratio and serum DAO level were significantly increased in control group and decreased in study group after operation.Blood TLC and HLA-DR expression in the study group were significantly higher than those in control group on postoperative day 5. Conclusion: Intravenous administration of Aln-Gln dipeptide can increase the serum Gln level,decrease the intestinal permeability,maintain the intestinal barrier and improve the immmunologic function in the early period of postoperative patients.Aln-Gln dipeptide can be used in the fast track surgery to help patients recover rapidly.

Objective: To explore the effects of 17 β-estrogen (E2) and 2-methoxyestradiol (2ME) on hypoxic induced factor-1α (HIF-1α) and alkane hydroxylase (AlkB) in experimental rats with ovariectomy and hypoxic pulmonary hypertension. Methods: A total of 60 healthy female SD rats with castrated surgery were randomly divided into 6 groups:①Routine oxygen group,②Routine oxygen + E2 group, the rats received subcutaneous injection of E2 (20 μg/kg?d),③Routine oxygen + 2ME group, the rats received 2ME (240 μg/kg?d) and④Hypoxia group,⑤Hypoxia + E2 group,⑥Hypoxia + 2ME group.n=10 in each group and all animals were treated for 8 weeks to establish the hypoxic pulmonary hypertension model. The mean pulmonary artery pressure (mPAP) was measured after bloodletting, right ventricle hypertrophy index (RVHI) was calculated and small pulmonary artery remodeling was observed by HE staining. The expression level of HIF-1α and AlkB were examined by RT-PCR and Western blot analysis. Results: Compared with Routine oxygen group, the rats in Hypoxia group had obviously thickened small pulmonary artery wall with narrowed lumen, increased mPAP and RVHI; the above changes in Hypoxia + E2 and Hypoxia + 2ME groups were relatively smaller, their mPAP and RVHI were higher than Routine oxygen group, while mPAP and RVHI were similar between Hypoxia + E2 and Hypoxia + 2ME groups. There were no real morphological changes in small pulmonary vessels in Routine oxygen + E2 and Routine oxygen + 2ME groups. The HIF-1α expression was obviously elevated in Hypoxia group than Routine oxygen group, while the elevation was less in Hypoxia + E2 and Hypoxia + 2ME groups. HIF-1α expression had no real changes in Routine oxygen+E2 and Routine oxygen + 2ME groups. The AlkB expression was obviously reduced in Hypoxia group than Routine oxygen group, while the reduction was less in Hypoxia + E2 and Hypoxia + 2ME groups. AlkB expression had no real changes in Routine oxygen + E2 and Routine oxygen + 2ME groups. Conclusion: Estradiol E2 and 2ME could remit pulmonary hypertension which might be via up-regulating AlkB expression and down-regulating HIF-1α expression in experimental rats with hypoxic pulmonary hypertension.

BACKGROUND:The incorporating of zeolites or porous fillers into polymer membranes can improve the pervaporation separation properties of membranes.But the effect mechanism of zeolites or porous fillers on membrane properties needs to be further studied.OBJECTIVE:The study was designed to prepare ZSM-5 zeolite incorporated chitosan membrane by solution blending method to investigate the effecIs of zeolite on membrane pervaporation properties.DESIGN:A controlled observation.SETTING:Dalian Institute of Chemical Physics,Chinese Academy of Sciences.MATERIALS:This study was performed at the Laboratory of New Type Membrane Separation Technology,Dalian Institute of Chemical Physics,Chinese Academy of Sciences in May 2006.Chitosan,with deacetylation degree of 75%-85%,was obtained from Sigma-Aldrich Chemical Company,USA;Dimethyl carbonate(DMC),with purity of 99%,was purchased from Fluka Chemical Company,USA:ZSM-5 zeolite was kindly supplied by Dalian Institute of Chemical Physics,Chinese Academy of Sciences,China;Methanol,with purity＞99.5%,were purchased from Shenyang Lianbang Chemical Company,China.METHODS:ZSM-5 zeolite incorporated chitosan membranes were prepared by solution blending method.MAIN OUTCOME MEASURES:①Swelling and sorption of ZSM-5 zeolite-incorporated chitosan membranes in the DMC/methanol mixture.②Effects of zeolite content in the membrane and operating temperature on pervaporation properties.RESULTS:Scanning electron mieroscope demonstrated that zeolite was uniformly distributed in the membrane matrix and the membranes were free from possible defects.The separation selectivity of dimethyl carbonate(DMC)/methanol mixtures was dominated by solubility selectivity rathcr than diffusivity selectivity.Swelling degree increased and the permeation flux of the membranes increased significantly with the zeolite content increasing.From the temperature-dependent permcation values,the Arrhenius activation parameten were estimated.CONCLUSION:The pervaporation results indicated that the membranes incorporated with the ZSM-5 zeolite exhibited better separation properties for DMC/methanol mixtures comparing with homogeneous chitosan membranes.

Objective To study the ultrasonographic and acoustic contrast features of breast fibroadenoma and breast cancer and explore the value of contrast enhanced ultrasonography in the differential diagnosis of benign and malignant breast tumors. Method A retrospective analysis of 18 cases breast fibroadenoma and 12 cases breast cancer in the performance of contrast-enhanced ultrasound was done. Results After contrast agent injection, tumor dimension increased in 4 cases with breast fibroadenoma and 7 cases with breast cancer. The ultrasonographic and acoustic contrast features of breast fibroadenoma showed no significant changes. They showed stenosis, perpendicular and circumambulates vascular shape. The breast cancers significantly increased the number of tumor blood vessels with the thicker,tortuous blood vessels into the tumor. Conclusions The contrast enhanced ultrasonography assessed more accurate size of tumors. The image displayed grown sizes, more vascularity and bending vascular shape in the breast cancer. It was more accurate than gray-scale ultrasound on diagnosing breast cancer.

Many investigations showed that abnormal blood insulin level is associated with the pathogenesis of Alzheimer′s disease and its clinical manifestation, suggesting that increasing blood insulin level and/or improving insulin sensitivity seem to be helpful for patients with Alzheimer′s disease.
