Objective To study the relationship between polymorphism of NAT2 gene and the susceptibility of osteosarcoma. Methods Using serum samples of patients with osteosarcoma , NAT2 gene polymorphism was determined by PCR-RFLP to observe M1, M2 and M3 mutant genes, NAT2 genotype and allele distribution. Slow acetylation and rapid acetylation genotype between groups in the distribution were also detected. Moreover , the relationship between the clinical characteristics of osteosarcoma and NAT2 genetic polymorphism were analyzed. Results From January 2010 to September 2015, 126 patients with osteosarcoma were enrolled as a case group, and 119 healthy persons in the same period were as the control group. In the control group, the frequency of NAT2 genotype (homozygous wild type (wt/wt and miscellaneous synthetic mutant WT/ MX, homozygous mutant MX/MX) were 30.95%, 50.79% and 18.25% respectively; In the experimental group were 47.06%, 46.22% and 6.72% respectively. The frequency of the two groups was statistically significant (P <0.05). Rapid NAT2 acetylator genotype of suffering from the risk of osteosarcoma 1.782 times slow acetylation genotype (P < 0.05). Compared to rapid acetylation genotype patients with osteosarcoma, slow acetylation genotype patients has smaller tumor volume (P = 0.008),lower differentiation degree of tumor (P = 0.011) and less occurrence of distant metastasis (P = 0.001). Conclusion The rapid acetylation genotype of NAT2 gene may be a risk factor for osteosarcoma.

Objective To explore the influence of the lentiviral vectors-mediated mouse genetic engineering regulatory T cells (Treg) infused after allogeneie bone marrow transplantation (allo-BMT)on graft-versus-host disease (GVHD) in mice.Methods Lentivirus-mediated expression of Forkhead box P3 (Foxp3) converted CD4~+ CD25~- T cells from Balb/c mice into engineered Tregs in vitro.An allo-BMT model of Balb/c→C57BL/6 mice was established.Mice were randomly assigned into four groups:(1) The recipients in engineering Treg group were injected with 5×10~6 donor bone marrow cells and 5×10~6 splenoeytes plus 5×10~6 genetic engineering Treg;(2)The recipients in transplantation control group were iniected with 5×10~6 donor bone marrow cells and 5×10~6 splenocytes;(3) The recipients in radiation group were injected with 0.2 ml RPMI 1640;(4)The recipients in empty vector control group were injected with 5×10~6 donor bone marrow cells and 5×10~6 splenocytas plus 5×10~6 empty vector transduced CD4~+ CD25~- T cells.Survival time,clinical GVHD Score or histopathological analysis(skin,liver and small intestine) were observed after allo-BMT.Chimerism of bone marrow cells from recipients survived for 60 days after transplantation was measured Results The mean survival times in radiation group, transplantation control group,erIgineering Treg group and empty vector control group were (8.8±0.6),(36.7±2.5),(51.6±4.0) and (34.1±2.3)days respectively.The survival time in engineering Treg group was signiticantly prolonged as compared with other groups as judged by the log-rank test(P<0.05).Histopathological ahalysis in several target organs (skin,liver and small intestine)confirmed the presence of severe GVHD in transplantation control group and empty vector control group. No histological signs of GVHD were observed in recipients in engineering Treg group and clinical GVHD scores in this group were significantly decreased compared to transplantation control group and empty vector control group. Conclusion Co-injection of genetic engineering Treg can efficiently prevent recipients from lethal GVHD during allo-BMT in mice

Objective To explore the influence of the lentiviral vectors mediated mouse genetic engineering regulatory T cells(Tr) infused after allogeneic bone marrow transplantation(allo-BMT) on graft-versushost disease(GVHD) in mice. Methods Lentivirus-mediated expression of forkhead box P3 (Foxp3) converted CD4 + CD25 - T cells from BALB/c mice into engineered Tr in vitro. An allo-BMT model of BALB/c→C57BL/6 mice was established. After irradiation, the recipients were injected with donor cells along with genetic engineering Tr. Survival time, histopathological analysis, serum levels of inflammatory cytokines were observed after allo-BMT. Results The mean survival times in radiation group, transplantation control group, engineering Tr group and empty vector control group were ( 8.8 ± 0.6 ) d, ( 36.7 ± 2.5 ) d, ( 51.6 ± 4.0 ) d and ( 34.1 ± 2. 3 ) d. The survival time in engineering Tr group was significantly increased as compared to other groups as judged by the log-rank test ( P ＜0.05 ). Histopathological analysis in several target organs( skin, liver and small intestine) confirmed the presence of severe GVHD in transplantation control group and empty vector control group. No histological signs of GVHD were observed in recipients in engineering Tr group. The serum levels of IFN-γ, IL-2 and TNF-α were all increased after transplantation in above groups. The peaks of concentrations of IFN-γ, IL-2 and TNF-α in engineering Tr group were significantly decreased compared to transplantation control group and empty vector control group at day 21 ( P ＜ 0. 05 ). Conclusion Co-injection of genetic engineering Tr can efficiently prevent recipients from lethal GVHD during allo-BMT in mice by reducing the serum levels of inflammatory cytokines.

Objective This study aimed to establish the leukemia mouse model by using EL4/DsRed cell line expressing red fluorescent protein (DsRed) and to evaluate the model. Methods After total body irradiation with X-ray of 7.0 Gy, C57BL/6 mice were inoculated 5×106 bone marrow cells mixed different numbers of EL4/DsRed cells via tail vein. The model was evaluated by flow cytometry (FCM), reverse transcriptase-polymerase chain reaction (RT-PCR), and histopathology. Results The incidence of leukemia was 100 %. The presence of EL4/DsRed cells was found in liver, spleen, bone marrow and peripheral blood of recipients by FCM two weeks after transplantation. Pathological section revealed that all recipients had several organs infiltration apparently. With the increase in the number of inoculated tumor cells, the survival time of recipients was reduced and the infiltration of leukemia cells in organs was more serious. Conclusion Mouse leukemia model was successfully established when C57BL/6 mouse was intravenously transplanted with ≥5×102 EL4/DsRed cells. The model could be employed usefully in the future research such as the pathogenesis of leukemia and minimal residual disease (MRD).
