Objective To investigate the expression of IFN-α of the peripheral blood monocytes (PBMC) stimulated by bacille Calmeue-Guérin (BCG) expressing recombinant human B7-2, and the antitumor effect of BCG activated killer cells(BAK). Methods Expression of human B7-2 was detected by SDS-PAGE and ELISA. Recombinant BCG and wild-type BCG were used to stimulate PBMC in different concentrations in vitro. Supernatant was collected at various time points and IFN-α was detected by an enzyme-linked immunosorbent assay (ELISA). MTT assay was used to observe the effects of recombinant BCG on proliferation of T cell, and LDH assay was used to study antitumor cytotoxicity of BAK cells. Results The concentration of human B7-2 in culture was 3.8 U/ml by ELISA. Compared with wild-type BCG, recombinant BCG can induce more IFN-α. The results of the LDH release assay showed that the anti-tumor activity of BAK cells stimulated by recombinant BCG was 2.14 fold higher than that of wild-type BCG. Conclusion The expression of IFN-α in PBMC stimulated by recombinant BCG is higher than that stimulated by wild-type BCG, suggesting that enhanced antitumor activity of BAK when bladder cancer cells could be enchanced by using recombinant BCG.

Objective To investigate the effect of paclitaxel drug-coated balloon (DCB) dilatation in treating coronary in-stent restenosis (ISR) occurring after drug-eluting stent (DES) implantation,and to observe the long-term changes of the target vascular lumen area in order to clarify the curative effect of paclitaxel DCB in treating ISR.Methods Four patients with ISR whose clinical condition met the DCB indication were selected.According to the standard process,sufficient pre-expansion of ISR was performed first,then paclitaxel DCB dilatation was carried out to dilate the lesion segment of ISR,and no stent was implanted.Both coronary angiography and intravascular ultrasound (IVUS) were performed immediately after the treatment as well as 9 months to measure the minimum lumen area (MLA) and cross-sectional area (SA) of the stent,and the intimal hyperplasia was also been evaluated.Results In all 4 patients,angiography performed immediately after paclitaxel DCB dilatation showed that neither dissection of the dilated segment of the target artery nor obvious residual stenosis was observed.Angiography performed 9 months after the treatment revealed that all dilated segments of the target arteries were patent,and no pronounced restenosis of stent segment was seen.IVUS examination was indicated that MLA became enlarged,SA showed an increasing trend,and intimal hyperplasia showed a tendency to be inhibited.Conclusion For the treatment of ISR,pure paclitaxel DCB dilatation can obtain long-term lumen area enlargement,thus,repeated stent implantation can be avoided,which,in turn,can reduce the risk of ISR recurrence.Paclitaxel DCB dilatation can locally release paclitaxel,which has curative effect on the coronary artery wall to inhibit the excessive proliferation of intima.

Objective:To identify the immune characteristics elicited by immunogen prepared in two different ways against a 36AA-peptide. Methods：Rabbits were immunized by a 36-AA-hapten coupled with carrier proteins or recombinant fusion protein separately. The kinetics and specificities of antibody responses were compared. Results：After about 3 months of primary immunity, the antisera elicited by two kinds of immunogen reached the peak titer. The highest titer elicited by the immunogen prepared with coupled-hapten method reached 1∶12 000, while the highest titer elicited by the immunogen prepared with gene engineering method was 1∶6 000. But the immune response produced by the recombinant fusion protein was more long-lasting. Conclusion：Both kinds of immunogen can successfully elicit 36-AA specific antibody response in rabbits, which have different immune characteristics. To couple the hapten with vector proteins is a quicker and more effective way to prepare the immunogen.

Objective To discuss the effect and safety of modified XELOX regimen for the treatment of colorectal cancer with he-patic metastases.Methods A retrospective analysis on the clinical data in 18 patients with colorectal cancer with hepatic metastases was performed in our hospital.The diagnosis in all patients was confirmed by biopsy and colonoscopy,and the primary lesion was not resected but with at least 2 courses treatment with modified XELOX regimen (intravenous infusion of oxaliplatin changed into ar-terial perfusion and 1-hour slow perfusion with indwelling catheter).The intrahepatic metastases were detected by CT and/or MRI and the primary focus was examined by enteroscopy every 2 months.A follow-up on survival time was performed and the objective response was evaluated in accordance with RECIST criteria.SPSS 1 9.0 was used for an analysis by Kaplan-Meier method.Results (1)Curative effect was evaluated in all 18 patients and TACE has been used for 1 1 5 times.The median OS was 14.0 months with 95% CI (9.6,18.4),and the median PFS was 8.0 months with 95% CI (5.2,10.8)including CR in 2,PR in 7,SD in 4 and PD in 5.The efficiency rate (RP)was 50.0% and the clinical benefit rate (CBR)was 72.2%;(2)The post-treatment adverse reactions mainly included fever,nausea,emesis,pain,impaired liver function,myelosuppression and peripheral sensory neuropathy,most of which were at Level Ⅰ-Ⅱ without treatment-related death.Fever with different degrees occurred in all patients,and nausea and emesis in 13.Pain and abnormal liver function occurred within 3-5 days after TACE with less than Level 2.Conclusion Modified XELOX regimen is practically effective in treating colorectal cancer with hepatic metastases.With a high objective response rate,it can improve patients'living quality and increase excision rate with tolerable adverse reactions.

Objective To investigate the association of lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms with metabolic syndrome. Methods PCR-RFLP was used to detect lipoprotein lipase Hind Ⅲ and S447X genotypes in 401 subjects(including 201 controls, 200 metabolic syndrome patients). Results ( 1 ) The levels of waist circumference ( WC ) , hip circumference ( HC ) , waist-to-hip ratio ( WHR ) , body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure ( DBP) , total cholesterol ( TC) , triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and fasting plasma glucose (FPG) were significantly different between metabolic syndrome group and control group (all P< 0.05). (2)The frequencies of H+H+ genotype,H+allele,SS genotype, and S allele for metabolic syndrome were all significantly higher than those for controls( H+H+ genotype:66. 5% vs 54.2% ,P=0.012; H+ allele:78.0% vs 71.4%, P=0.031;SS genotype:89.5% vs 77. 1% , P = 0.001; Sallel:94.5% vs 87. 56% , P = 0.001). (3) The levels of WC, HC, WHR, BMI, SBP, DBP, TG, LDL-C, and FPG in H + H-/H-H- genotype were significantly lower than those in H+H+ genotype, HDL-C was significantly higher than that in H+H+ genotype ( all P<0. 05). The levels of WC, HC, WHR, BMI, SBP, DBP, TC, TG, and FPG in SX/XX genotype were significantly lower than those in SS genotype, HDL-C was significantly higher than that in SS genotype ( all P< 0.05). (4)Multi-way logistic regression analysis suggested that risk factors for metabolic syndrome were smoking, drinking, and SS genotype (OR value was 4.289,2.268, and 2. 597, respectively ). (5) Result of interaction analysis among different factors indicated that the risk for metabolic syndrome in smoker with SS genotype was 3. 996 times of non-smokers with SX/XX genotype. Conclusions The lipoprotein lipase gene S447X polymorphism is associated with metabolic syndrome risk in Kazakh, and SS genotype and S allele may serve as genetic risk factors of metabolic syndrome, H + H-/H-H- and SX/XX genotypes yield beneficial effect for lipid and blood pressure. SS genotype and smoking may exist additive effect.

Questionnaire-based survey, physical examination, and blood testing were conducted according to cluster random samplings in Kazakh residents in Xinjiang.2 760 samples were collected to analyze the association of different strata of waist circumference and clustering of metabolic syndrome (MS) components.Accoding to International Diabetes Federation standard, the prevalence of ≥1and ≥2 components of MS showed increasing trend with the increase of waist circunference, and odds ratio of clustering of MS components also increased significantly.The distance of receiver operating characteristic curve was the shortest and the prevalence of MS was 22.1% ;22.4% in men, and 21.9% in women;when the waist circumference was ≥91 cm for men, and ≥88 cm for women.
