Objective To investigate the mRNA expression of survivin, livin and XIAP gene in peripheral blood of patients with gastric cancer and its relationship with clinico-pathological features.Methods This study included 50 patients with gastric cancer and 20 healthy donors. The expression of survivin, livin and XIAP gene was detected by reverse transcription-quantitative polymerase chain reaction (RT-QPCR) using a molecular beacon probe, while recombination plasmid containing the sequence of survivin, livin and XIAP was standard. The relationship between copies of survivin, livin and XIAP gene expression in peripheral blood with gastric cancer and clinical data was analyzed. Results A linear standard curve was obtained between 103 ~ 1010 copies. The copies of survivin, livin and XIAP mRNA in peripheral blood of patients with gastric cancer did not correlate with gender, age, and histological types ( P > 0.05). There were positive relationships between copies of survivin, livin and XIAP gene with lymph node metastasis and TNM stage (P <0.05 ). The expression of survivine, livin and XIAP was all negative in peripheral blood of healthy people. 52% (17/33) of patients suffered from recurrence or metastasis who had positive expression of survivin and/or livin and/or XIAP mRNA, while it was 18% (3/17)among the negative survivin and/or livin and/or XIAP mRNA caces ( P < 0.05). Conclusions The expression of survivin, livin and XIAP mRNA can be used to detecte micro-metastasis in peripheral blood circulation of gastric cancer.

Objective:The purpose of this study is to investigate the expression of tumor stem cell marker aldehyde dehydrogE-nase 1 (ALDH1) in breast cancer and its clinical significance. Methods:The expression of ALDH1 protein was examined by immunohistochemical staining in 92 breast cancer tissues. The correlation analysis and diseasE-free survival analysis of patients was evaluated based on the clinical follow-up data. Results:Expression of ALDH1 protein had a significant correlation with progesterone receptor (PR) and cerb-B2 (P<0.05), but had no significant correlation with age, tumor size, clinical staging, and lymph node metastasis (P>0.05). The 2-year diseasE-free survival rate of AlDH1-positive patients was lower than that of ALDH1-negative patients (P<0.05). ALDH1-positive patients, who received CEF regimen chemotherapy and hormone therapy, had lower 2-year diseasE-free survival rate than that of ALDH1-negative patients (P<0.05). Conclusion:The decreased diseasE-free survival rate of ALDH1-positive patients is related with drug resistance. ALDH1 could be used as an independent factor for predicting the prognosis of breast cancer.

Objective To investigate the survival of islet isograft in NOD mice treated with islet antigen-specific regulatory T cells.Methods GAD-65 antigen pulsed immature dendritic cells (imDC) were used to induce naive T cells into islet antigen-specific regulatory T cells.NOD mice which had progressed to type 1 diabetes (T1DM),as the recipients,received islet isografts (500 IEQ) under renal capsule from NOD mice without T1DM.In NOD mice in control group without transplantation,the changes in blood glucose (BG) were observed.NOD mice in simple islet transplantation group were given islet isograft without Treg infusion.In experiment group,NOD mice were infused with 1 × 106 islet antigen-specific regulatory T cells on the 1st day before transplantation,subsequently underwent islet isotransplantation.The survival of the islet isograft was evaluated by BG levels and the pathological changes were observed.Results BG levels were sustained above 11.1 mmol/L in control group.In simple islet transplantation group,BG level was decreased to the normal level in 1 ~2 days after transplantation,and began to rebound in 7~ 17 days posttransplantation and maintained at the preoperative level.The mean survival of the islet isograft in the NOD mice was (12.2 ± 2.6) day;In experiment group,BG level was decreased to the normal level in 1 ~2 days after transplantation,rebounded above 11.1 mmol/L in some mice on the 27th day after transplantation,and rebounded above 11.1 rnmol/L on the 43th day in all mice.The mean survival of the islet isograft in the NOD mice was (35.2 ± 4.3) days,which was significantly prolonged compared to simple islet transplantation group (P< 0.01).In simple islet transplantation group,the islet isograft was infiltrated by many lymph cells and damaged severely,and only few residual islet cells secreted insulin without complete islet existing in insulin staining.The islet isograft in experiment group was intact on the 15th day,with little lymph cell infiltration and a great number of islets secreting insulin.Conclusion Infusion of islet antigen-specific regulatory T cells induced by imDC and islet antigen GAD-65 in vitro could delay the destruction of autoimmune system and prolong the islet isograft survival in NOD mice.

Objective To investigate the proliferation inhibition and the apoptosis induction effect of brucine on human chronic myeloid leukemia cell line HL-60 cells.Methods HL-60 cells were exposed to various dosages of brucine 24,48,72 h respectively,MTT method was used to assay the growth inhibition effect of brucine on HL-60 cells and the IC50 of brucine was evaluated at the same time.The morphology was observed by AO/EB stains.The cell apoptosis and cell cycle was tested by flow cytometry with Annexin V-FITC/PI double staining and PI labeling respectively.Results The results indicated that the brucine displayed significant anti-proliferative effect on HL-60 cells in a dose-and time-dependent manner,with IC50 value of 211.8 μg/ml(24 h),107 μg/ml(48 h),83 μg/ml(72 h)respectively.The most significant inhibition was observed at 320 μg/ml for 48 h.In this condition,apoptosis morphology was induced by brucine with nuclear chromatin condensation,most of the nuclears were orange stained and condensation-like or bead-like,which was consistent with the Annexin V-FITC/PI results.The cell apoptosis rates were(2.1±1.1)%,(21.3±1.2)%,(38.6±1.3)%,(58.5±4.1)%,(75.3±0.87)%and(66.2±0.75)%in different dose of brucine,respectively.At the same time,the cell cycle analysis results showed that the cell ratio in G0/G1 phase was decreased while in G2/M and sub-G0 phases was increased,comparing with blank control group.Conclusion Brucine can inhibit cell growth dramatically,which may be related to the cell apoptosis and the cell cycle arrest.

Objective To investigate the feasibility of induction of experimental chronic pancreatitis rat model with L-arginine.Methods Animals were randomly divided into control group,arginine 12 h group,arginine 24 h group and arginine 7 d group with 10 rats in each group.L-arginine solution was intraperitoneally injected twice with an interval of 1 h.Serum amylase and glucose levels at corresponding time points were detected and histopathological scores of pancreas were evaluated.Collagen in pancreas was stained with Van Gieson method.Results Serum amylase levels were (1 634±890 ) U/L,( 3 872±2 676 ) U/L,( 3 307±2 197)U/L and (1 561±304) U/L in control group,arginine 12 h group,arglnine 24 h group and arginine 7 d group,respectively.The serum amylase level in arginine 7 d group was significantly lower than those in arginine 12 h group and arginine 24 h group (P < 0.05 ).There was no significant difference in serum glucose level among all the groups.Histopathological scores were 0.8±0.4,5.1±2.6,6.5±2.2 and 4.5±1.6,respectively.The histopathological score of arginine 7 d group was significantly lower than those in arginine 24 h group (P < 0.05 ).Obvious collagen could be found in pancreatic parenchyma in arginine 7 d group,while little collagen was found in pancreatic tissue in control,arginine 12 h and arginine 24 h groups.Conclusions Injection of L-arglnine induced fibrosis in pancreatic parenchyma and proliferation of tubular complex 7 days later,and it could be used for chronic pancreatitis model induction.
