1.Application of biotherapy in recurrent or metastatic gastric cancer.
Chinese Journal of Gastrointestinal Surgery 2011;14(8):569-572
Post-operative recurrence and metastasis remain the leading causes of death for patients with gastric cancer. The major determinants of recurrence and metastasis are the biological characteristics of cancer cells and the immunological status of the patients. In recent years, due to the target-specificity, biotherapy has yielded efficacious responses in diverse clinical applications for cancer treatment, partially for the treatment of recurrence and metastasis of gastric cancer. However, because of the high diversities in clinical manifestations, patients' condition, and tumor's characteristics, there is no ideal strategy of biotherapy established for the prevention and treatment of recurrence and metastasis in gastric cancer. Therefore, a lot of work need to be done in basic research and clinical trial to make the biotherapy effective in treatment of gastric cancer recurrence.

Human immunodeficiency virus (HIV) infection can cause variable movement disorders, including parkinsonism. HIV-related parkinsonism usually responds well to highly-active antiretroviral therapy (HAART), suggesting a possible reversible dysfunction of the dopaminergic system. We report the case of a 42-year-old man who presented with rapidly progressive symmetric parkinsonism, cognitive decline, and loss of postural reflex as the initial manifestation of HIV infection. A significant improvement of his parkinsonism after HAART demonstrates a potentially reversible dopaminergic system dysfunction secondary to HIV infection. A normal 99mTc-TRODAT-1 SPECT image after HAART treatment paralleled the clinical improvement in extrapyramidal symptoms. Early identification of HIV-related parkinsonism, especially in patients with symmetrical akinetic-rigidity and early loss of posture reflex, is important for its potential reversibility with HAART therapy.

Objective To explore the effectiveness of sandplay therapy combined with family counseling in children with school phobia and its influence of child′ self-consciousness. Methods Integrative sandplay therary with family consulting were used to treat 28 patients with school phobia regularly for 2 months. Sandplay and family consulting therapy were given once a week for 45 minutes . Clinical outcomes were assessed using CGI-GI and Piers-Harris children′s self-consciousness scale before and after treatment as well as 3 months posttreatment. Results Overall response rate was 85%. In addition, the physical appearance and characteristic factor before and after treatment were no significant difference (P>0.05). The rest of the various factors and total score compared with pre-treatment significantly improved (P<0.05). After treatment for 3 months, every factor in self-consciousness of children and total score were no significant difference (P>0.05). Conclusion Integrative sandplay therapy with family counseling has better and long-lasting treatment effect to self-consciousness of children with school refusal.

The aim was to construct and identify the mammalian expression vector of pCAG-IRES-SHIP-GFP and to detect whether it could express in human acute leukemia cell line K562.The cDNA fragment of SHIP obtained by RT-PCR was inserted into pCAG-IRES-GFP.The recombinant plasmid was confirmed by restriction enzyme digesiton,PCR and DNA sequecing.pCAG-IRES-SHIP-GFP was transfected into K562 cells with lipofectamine 2000.The expression of SHIP was determined by GFP fluorescence and Western blot analysis.FQ-PCR was used to quantitate SHIP mRNA.The expression of p-Akt,Akt were determined by Western blot.PI were tested by flow cytometry and MTT to verify whether exogenous SHIP could inhibit proliferation of K562 cells.The results showed that the correct constrution of the recombinant plasmid pCAG-IRES-SHIP-GFP has been shown by restriction enzyme digestion,PCR and DNA sequencing.pCAG-IRES-SHIP-GFP could express SHIP protein in K562 cells.The K562 cells viability after transfected with SHIP gene droped down.Western blot analysis showed that phospha-Akt308 and Akt473 were reduced to 38.7% and 68% respectively.It was concluded that the vector of pCAG-IRES-SHIP-GFP has been successfully constructed and it can be expressed in K562 cells.The expression of exogenous SHIP gene can lead to apoptosis of K562 cells by down-regulating the p-Akt expression.What found here might be one of the mechanisms involved in the pathogenesis of leukemia.

ObjectiveTo prepare high specific monoclonal antibodies(mAbs) against BP26 of Brucella(B.)melitensis.Methods A recombinant plasmid pET-28a-BP26 was constructed and transformed into competent Escherichia coli BL21 (DE3),and then the bacteria were induced by 1 mmol/L isopropylthio-β-D-galactoside (IPTG).After induction,the recombinant BP26 protein (rBP26) was purified by sodium dodecyl sulfate polyacrylamide gel electrophoresis(SDS-PGAE) and nickel ion affinity chromatography(Ni-NTA).Mice were inoculated with rBP26 antigens for three times at 2-week intervals.The first subcutaneous injection contained 100 μg rBP26 with 0.1 ml complete Freund adjuvant.The second subcutaneous injection was 50 μg rBP26 with 0.1 ml incomplete Freund adjuvant.The antibody titers to rBP26 were determined 2 weeks after each reimmunization.Three days before cell fusion,the mice with the highest titer were intraperitoneally injected with 50 μg rBP26 in 0.1 ml PBS.Pre- and post-immunization sera were collected and used as negative or positive controls for screening mAbs.Mice with the highest titer were sacrificed and spleen cells were isolated.The spleen cells of rBP26 immunized mice were fused with SP2/0 myeloma cells in a ratio of 5 ∶ 1 by polyethylene glycol(PEG) 1450.Antibody-producing hybridomas were primarily screened by an indirect enzyme-linked immunosorbnent assay(ELISA) with rBP26.Reactive hybridomas were subcloned for 3 times,then the strains of hybridoma cells secreting antibodies against BP26 were obtained.Supernatant of cloned hybridoma cultures was collected for mAb analyses.These mAbs were named by the hybridoma clone number and tested their reactivity to membrane proteins extracted(NMP) from B.melitensis vaccine strain(M5-90) by Western blotting and Dot-ELISA.mAbs isotyping and kappa(κ) or lambda(λ) light chain was identified by Mouse Monoclonal Antibody Isotyping Kit.Results A total of two mAbs reactive to rBP26 of B.melitensis were selected from antibody screening hybridomas by indirect-ELISA.The two mAbs were named 3C3 and 5A5,and identified as IgG1 (κ) and IgG2(κ),respectively.They could react with NMP from M5-90.Conclusions Results of identification show that two mAbs against rBP26 can be produced.The two mAbs can recognize natural BP26 protein,giving the experimental materials for further research on identification of its epitopes.
