BACKGROUND:Human mesenchymal stem cells derived from Wharton's jelly(WJCs)display the characteristics of MSCs as defined by the International Society for Cellular Therapy.They can be differentiated into bone,cartilage,adipose,muscle,and neural cells.They can also support the expansion of other stem cells,be weli-tolerated by the immune system,and have the ability to home to tumors.OBJECTIVE:To investigate biological changes of WJCs and brain tumor stem cells(BTSCs)co-cultured in vitro.METHODS:WJCs cultured by situ cultivation and BTSCs used enzyme digestion way respectively,and gathering the 3rd passage of WJCs though subculturing as well as BTSCs.Two kinds of cells co-cultured in 24-well plates in serum-free medium (SFM)without any growth factor.3 and 7 days after co-cultured respectively,CD133 expression of suspension cells in the 24-well plates were identified by flow cytometry,and immunofluorescence was performed for Nestin and glial fibrillary acidic protein (GFAP)expression of adherent cells.Co-culture supernatant(CCS)re-suspended 3~(rd) passage of BTSCs and cultured into 96-well plates at day 3,which were used to determine the difference in cell growth curve in both groups using a microplate reader.RESULTS AND CONCLUSION:With the cocultivation days increasing,the phenomenon that tumor sphere cells began to be decomposed,adherent and differentiated observed by an inverted microscope.BTSCs in the co-cultured group expressed GFAP and Nestin when adherent and differentiated.The higher degree of malignant brain tumor tissue used in culturing BTSCs was,the higher expression of CD133 in BTSCs was.CD 133~+ in BTSCs declined when co-cultured with WJCs.Growth curve of brain tumor stem cells cultured in CCS compared with in SFM at day 3,which indicates that the proliferation of BTSCs inhibited obviously.Results indicated that CD 133~+ expression and proliferative capacity of BTSCs went down and BTSCs underwent differentiation during the co-culture in vitro.

BACKGROUND:Bone marrow mesenchymal stem cells have low immunogenicity and immunomodulatory effect,but there are seldom reports concerning the immunomodulatory effect of Wharton's jelly-derived mesenchymal stem cells of human umbilical cord and its mechanims.OBJECTIVE:To investigate the immunomodulatory effects and mechanisms of Wharton's jelly-derived mesenchymal stem cells of human umbilical cord on varient peripheral blood T lymphocytes.METHODS:Mesenchymal stem cells were isolateded from Wharton's jelly of human umbilical cord by tissue culture.T lymphocytes from human peripheral blood were stimulated by phytohemagglutinin and co-cultured with umbilical cord Wharton's jelly-derived mesenchymal stem cells and umbilical cord Wharton's jelly-derived mesenchymal stem cells supernatant respectively to measure A value following 72 hours of coculture using multifunctional microplate reader.Expression of cytokines including transforming growth factor-beta 1(TGF-β1)and interferon-y(IFN-γ)was evaluated by enzyme-labeled immunosorbent assay.RESULTS AND CONCLUSION:Wharton's jelly-derived mesenchymal stem cells could inhibite the proliferation of T lymphocytes induced by phytohemagglutinin.The proliferation inhibition rate was 56%(P＜0.01).Wharton's jelly-derived mesenchymal stem cells supernatant also had inhibitory effects on proliferation of T lymphocytes induced by phytohemagglutinin,in a dose-dependent fashion.The proliferation inhibition rates were 8.3% and 27% respectively in the 50% Wharton's jelly-derived mesenchymal stem cells supernatant and 100% Wharton's jelly-derived mesenchymal stem cells supematant groups(P＜0.05).Wharton's jelly-derived mesenchymal stem cells significantly decreased γ-interferon secrted from T-lymphocytes(P＜0.05).The secretion of TGF-β1 was lower in the coculture of Wharton's jelly-derived mesenchymal stem cells and T lymphocytes group than Wharton's jelly-derived mesenchymal stem cells alone group(P＜0.05).These indicated that Wharton's jelly-derived mesenchymal stem cells and Wharton's jelly-derived mesenchymal stem cells supernatant have inhibitory effects on proliferation of T lymphocytes induced by phytohemagglutinin.The mechanims may be associated with cell contant and inhibition of v-interferon secrted from T-lymphocytes.

Chronic myeloid leukemia (CML) is a clonal hematologic malignancy. In recent years, its treatment mainly involves the application of tyrosine kinase inhibitors (TKI) targeting the BCR::ABL fusion gene, but some patients still develop drug resistance or drug intolerance during TKI treatment and enter into the advanced stages (include accelerated phase and blast crisis phase). This article reviews the research progress of novel TKI drugs, TKI combined regimens and other targeted drugs for treatment of advanced stages of CML.

Objective:To investigate the effect and mechanism of circular RNA (cirRNA) on the radiosensitivity of rectal cancer.Methods:The differential circRNAs in radiosensitive and radioresistant rectal cancer tissues (biopsy tissue before radiotherapy and chemotherapy) were detected by gene sequencing, and the effect of circRNAs on the radiosensitivity of colorectal cancer cells was further confirmed in vitro. Results:Through gene sequencing of rectal cancer tissue samples, 64 circRNAs were found to be highly expressed in radiosensitive rectal cancer tissues, and 36 circRNAs were lowly expressed in radiosensitive tissues. Ten differential circRNAs were selected and verified by qRT-PCR, and it was found that circATL2 was highly expressed in radiosensitive rectal cancer tissues. In vitro cell experiment indicated that up-regulation of circATL2 expression could significantly improve the radiosensitivity of rectal cancer. Subsequently, 8 miRNAs lowly expressed in radiosensitive rectal cancer tissues were analyzed. The direct binding relationship between miR-205 and circATL2 was confirmed by dual luciferase reporter assay. The rescue experiment confirmed that circATL2 in rectal cancer regulated the radiosensitivity of rectal cancer through miR-205. Conclusion:circATL2 regulates the radiosensitivity of rectal cancer by binding to miR-205.

Purpose To explore the molecular features of diffuse large B-cell lymphoma(DLBCL)with high expression of MYC.Methods The clinical data of 45 cases of DLBCL were collected.Immunohistochemical EnVision method was used to classify the patients into the group with high expression of MYC and the group with low expression of MYC.All samples were subjected to DNA targeted sequencing and molecular typing was performed using the LymphGen online tool.Cellular origin was determined by using the Lymph2Cx method.The correlation be-tween MYC overexpression and clinicopathological parameters was analyzed by the x2 test and Fisher precise test.Survival curves were drawn and survival-related factors were analyzed u-sing Cox univariate and multivariate regression.ResultsCases were classified into DLBCL with high expression of MYC(n=17)and DLBCL with low expression of MYC(n=28).Com-pared to the group with low expression of MYC,the group with high expression of MYC had more PIM1,MYD88,CD79B,CD58 and PRDM1 mutations(76.5％vs 28.6％,70.6％vs 32.1％,58.8％vs28.6％,29.4％vs3.6％,29.4％vs 3.6％,P＜0.05),MCD were more frequently found(58.8％vs 10.7％,P=0.001),GCB were rarely found(17.6％vs 50.0％,P=0.030).Overall survival was significantly shorter in DLBCL with high expression of MYC(P＜0.05).Cox multi-factorial analysis showed that age was an independent prognostic factor for DLBCL(P＜0.05).Conclusion Patients with high expression of MYC were frequently characterized as MCD and ABC,and PIM1,MYD88,CD79B,CD58 and PRDM1 muta-tions were common.Patients with high expression of MYC had a poorer prognosis.

Objective To examine the correlation between the gene of phosphate and tension homology deleted on chromosometen (PTEN gene) polymorphism and schizophrenia (SCZ) associated with the type 2 diabetes mellitus (T2DM ) in Shanghai Han population. Methods The study recruited 591 long-stay schizophrenic inpatients including 304 with and 287 without type 2 diabetes mellitus, 206 patients with the type 2 diabetes mellitus and 205 normal subjects from Shanghai Han population. SNPs of PTEN gene (rs1234225, rs12569998, rs1234223) were genotyped by using Taqman genotyping. The frequency distributions of allele, genotype and haplotype between groups were analyzed. Results There were significant differences in the frequency of rs1234223 genotype (P=0.01) and allele distribution (P=0.02) between the SCZ with type 2 diabetes mellitus group and the SCZ without type 2 diabetes mellitus group. The difference of genotype frequencies remained statistically significant (P=0.03) but the allele distribution was not (P=0.06) after Bonferroni correction. Haplotype analysis showed that TTC haplotype was less common in the SCZ with type 2 diabetes mellitus group than in the SCZ without type 2 diabetes mellitus group (P=0.02). Conclusions PTEN gene may be a susceptibility gene for schizophrenia with type 2 diabetes mellitus in Chinese Han population. The TTC haplotype may be a protective factor for schizophrenia with type 2 diabetes mellitus.

Objective: To investigate the clinical and microbiological characteristics of Myroides odoratimimus producing MUS-1 carbapenemase. Methods: A strain of gram-negative bacterium isolated from the urine sample of one patient hospitalized in the oncology department of Affiliated Hospital of Xuzhou Medical University was identified by the Vitek 2 automatic microbial analyzer and 16S RNA sequencing, and its bla MUS-1 gene was detected with PCR. The minimum inhibitory concentrations (MICs) of antimicrobial drugs were determined by the broth dilution method. Results: One strain of MUS-1 carbapenemase producing Myroides odoratimimus was found. The drug susceptibility test showed that it was resistant to most of antibiotics conventionally used, but sensitive to minocycline and meropenem, the MIC of imipenem was 8 μg/mL, which was judged as intermediate. Conclusion The bla MUS-1 gene may be the cause leading Myroides odoratimimus to resistant carbapenems drugs.
