Objective To prepare the mB7-1-GPI-anchored Lewis vaccine and investigate its antitumor effects. Methods mB7-1-GPI was incorporated on Lewis tumor cells and mB7-1-GPI-anchoring tumor vaccine was prepared. The anti-tumor immunity induced by the prepared mB7-1-GPI-anchored Lewis tumor cell vaccine in tumor-bearing mice was observed. Results Flow cytometric analysis showed that mB7-1-GPI were positively expressed on the surface of Lewis tumor cells. After Lewis tumor cells incubated with mB7-1-GPI, the positive rate (PR) of mB7-1 antigen was 95.8% (0h), 93.6% (4h), 91.1% (8h) and the fluorescence intensity (FI) was 11.2(0h), 10. 6(4h), 9. 8(8h). The IL-2 and IFN-γ production of splenic lymphocytes + lewis cells was (25.9 ± 1.4) pg/ml, (56. 0± 3. 5 ) pg/ml. The IL-2 and IFN-γ production of splenic lymphocytes + lewis/mB7-1-GPI was ( 871.3 ± 10. 4 ) pg/ml, ( 1329. 0 ± 11.9 ) pg/ml. In 25 days, the mean diameter of tumor of Lewis/mB7-1 -GPI was shorter than Lewis( 1.4 ± 0. 21 )cm & ( 2. 5 ± 0. 27 )cm , P ＜ 0. 05 ). Lewis tumor cell-bearing C57BL/6 mice treated with Lewis/mB7-1-GPI vaccine survived much longer than mice treated with Lewis vaccine ( 75.2 ± 2. 0 ) d & (40. 2 ± 2. 0 ) d ( P ＜ 0. 05 ). Conclusion The Lewis tumor vaccine prepared with mB7-1-GPI fusion protein significantly inhibited the tumor growth in Lewis bearing mice. It represented an useful new strategy for attaching immunological factor onto tumor cell surfaces without genetic manipulation.

OBJECTIVE:To observe the clinical efficacy and safety of recombinant human endostatin (rh-endostatin) combined with Lobaplatin for injection and irinotecan injection in the treatment of advanced recurrent small cell lung cancer (SCLC). METHODS:A total of 88 patients with advanced recurrent SCLC in our hospital were divided into control group (41 cases) and observation group (47 cases) according to random number table. Control group was given Irinotecan injection+Lobaplatin for injection. Observation group was additionally given Recombinart human endostatin injection 15 mg added into 0.9%Sodium chloride injection 250 mL,ivgtt,qd,for consecutive 14 d,every 14 d. A treatment course lasted for 28 d,and both groups were treated for 2 courses. The clinical efficacy,the levels of serum carcinoembryonic antigen(CEA),the scores physical state (ECOG) and quality of life (QOL) before,after treatment were observed in the two groups,and the survival and adverse reactions of the two groups were compared. RESULTS:The total response rate of observation group was 59.6%,which was higher than 43.9% of control group,but there was no statistical significance (P>0.05). Before treatment, there was no significant difference in serum CEA levels,ECOG scores or QOL scores,between 2 groups(P>0.05);after treatment,the serum CEA levels of the two groups were significantly decreased,and the observation group was significantly lower than the control group,with statistically significant (P<0.05). In observation group,ECOG scores decreased while QOL scores increased significantly,and significantly better than the control group,with statistical significance(P<0.05). The overall survival(OS)of observation group was 16.8 months,which was significantly higher than 11.5 months of control group,with statistical significance (P<0.05). The incidence of leucopenia in observation group was significantly higher than control group;the incidence of leucopenia and abnormal liver function were significantly lower than control group,with statistical significance(P<0.05). CONCLUSIONS:Rh-endostatin injection combined with lobaplatin and irinotecan can improve serum CEA levels and the quality of living aswell as prolong the survival time.

The specific ScFv gene against botulinum neurotoxin A (BoNTa)was cloned into pPIC9k. Positive integrators were screened by increasing the dose of G418 in culture and expressed in Pichia pastoris GS115. As a result, engineered recombinant clone were obtained. 26 kD product of interest was seen easily in SDS-PAGE. Expression of human ScFv got the highest level 15% of total secreted proteins during 72～84 h after 1% methanol inducing. Purification of ScFv was finished by two steps: gel filter and ion exchange. Competing ELISA showed that recombinant ScFv could compete with antiserum to specific bind BoNTa.

Background Vitronectin is a glycoprotein that has a variety of functions.Its expression was markedly higher in the retina of oxygen induced mice,which was confirmed in our animal model,and also increased in human umbilical vein endothelial cells (人 UVECs) that were cultured in high glucose.However,there was no evidence that showed vitronectin was involved in retinal neovascularization.Objective This study was to observe the influence of vitronectin on cytoskeleton remodeling,cell migration and blood vessel formation in 人 UVECs conditioned by high glucose.Methods 人 UVECs were cultured in high glucose and the expression of vitronectin was knocked down using RNA interference technology.The experiments were divided into the high glucose group (人 UVECs were conditioned with DMEM medium that contained 50 mmol/L glucose),negative interference group (人 UVECs were transfected with control siRNA in advance,and then were conditioned with DMEM medium that contained 50 mmol/L glucose) and positive interference group (HUVEC were transfected with vitronectin siRNA in advance,and then were conditioned with DMEM medium that contained 50 mmol/L glucose).The protein expression of vitronectin was measured by Western blot,and the microfilament cytoskeleton of 人 UVECs was examined by immunofluorescence cytochemical staining followed by fluorescence microscopy.Cell migration ability in a scratch wound assay and blood vessel formation ability in a matrigel assay of 人 UVECs were evaluated.The general differences were analysed by One-Way ANOVA ;further contrasts of the two groups were analysed by the LSD-t test.Results The differences in vitronectin expression of the three groups were not obvious at 0 hour (F=1.064,P＞0.05).After 24 hours,vitronectin expression was highest in the high glucose group,lower in the negative interference group,and the lowest in the positive interference group,and the differences were significant (F =15.519,P＜0.05).After 48 hours,vitronectin expression of the three groups displayed the same pattern,and the differences were also significant (F=37.521,P＜0.05).Immunofluorescence showed that the cytoskeleton structure was most obvious in the high glucose group,moderate in the negative interference group,and was the least obvious in the positive interference group,after both 24 hours and 48 hours.In the scratch wound assay,the cell migration ability of the high glucose group was the highest,lower in the negative interference group,and the lowest in the positive interference group after 24 hours,and the differences were significant (F=90.685,P＜0.05).After 48 hours,the cell migration abilities of the three groups displayed the same pattern,and the differences were also significant (F=67.880,P＜0.05).In the matrigel assay,after 6 hours,the number of blood vessels formed in the high glucose group was more than that in the negative interference group,and the least amount was found in the positive interference group.The differences among of them were significant (F =86.653,P＜0.05).The number of blood vessel formed in the positive interference group was also the lowest after 12 hours,and the differences were also significant (F=18.992,P＜0.05).Conclusions Vitronectin can bring about cytoskeleton remodeling,increase in cell migration,and enhancement of blood vessel formation in 人 UVECs conditioned in high glucose.It may be one of the important influence factors of diabetic retinopathy.

Immobilization conditions of Candida tropicalis to be absorbed in polyurethane foam carrier materials were studied on the xylitol production from corn hemicellulosic hydrolysate. Optimum batch-fermentation conditions were as follows: inoculum amount, 7% (volume ratio); polyurethane foam quantity, 1.0 g/100 mL; 30?C; initial pH, 6.0. Shaking speed was divided into two-phase to accommodate the dissolved oxygen, with 200 r/min at 0~24 h and 150 r/min at 24 h~46 h. The immobilized cells on polyurethane foam carrier have high density and good resistance to inhibitors in the hydrolysates. Average xylitol yield and volumetric productivity of polyurethane foam immobilized fermentation were much higher than the fermentation without immobilization. Corn cob hydrolysates can be directly biotransformed to xylitol without decoloration or ion-exchange treatment. This process can effectively reduce production costs, and it shows broad prospects of applications. Average xylitol yield was 67.6% and xylitol volumetric productivity was 1.92 g/(L?h).
