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 To investigate the effect of jejunal casein perfusion on pancreatic exocrine secretion in experimental acute necrotic pancreatitis (ANP) rats and analyze the neuromechanism that may be involved. Methods 30 SD rats were randomly divided into three groups (control group, ANP group and ANP jejunal nutrition group). Experimental ANP was induced by intra pancreatic duct injection of sodium taurocholate (STC). Animals in ANP jejunal nutrition group were given jejunal casein perfusion 24h after model induction, while control group and ANP group received jejunal saline perfusion. Pancreatic juice was collected every 15 min for six times and the volume of pancreatic juice and protein in pancreatic juice were detected. After jejunal nutrition c-Fos expression in nucleus tractus solitarii (NTS) was determined by immunohistochemistry method in three groups. Results There was no significant difference between the volume of pancreatic juice at different time points in ANP group and ANP jejunal nutrition group, however, these parameters were significantly lower than that of control group (P < 0. 05). There was no significant difference among the 3 groups in the protein level in the pancreatic juice during jejunal nutrition infusion, however, during the periods of 0 ～ 15 min, 15 ～30 min, 30 ～45 min and 75 ～90 min, the protein levels in the pancreatic juice in ANP and ANP jejunal nutrition group were lower than that of control group (P < 0.05). After jejunal perfusion, c-Fos expression was found in ANP jejunal nutrition group but not found in ANP and control groups. Conclusions Jejunal casein perfusion enhanced NTS c-Fos expression, but did not increase the volume of pancreatic juice and protein.

To report a case of 16-month-old boy with anhidrotic ectodermal dysplasia with immunodeficiency who experienced disseminated herpes simplex infection. From 2 months of age, the patient experienced multiple pyrexial episodes of undetermined origin, which responded well to anti-inflammatory agents after undressed. Abnormal sweat with dry skin was noted; therefore, the skin biopsy of right axilla was performed at 7 months of age, and suggested a diagnosis of anhidrotic ectodermal dysplasia. Since 6 months of age, he developed recurrent upper respiratory infections and 2 episodes of pneumonia. Twenty days before, several glossal erosions occurred in the patient, supervened by painful and erosive eruptions and numerous blisters around the mouth and both hands with hyperpyrexia. Four days before, the patient was transferred to the department owing to skin lesion exacerbation. Cutaneous examination showed multiple crested or ulcerated plaques distributed eriorificially (mouth and nasal cavity) on the face. Several irregular, demarcated ulcers were scattered on the buttocks, scrotum and lower limbs, surrounded by grouped and umbilicated vesicles arising on erythema. Both hands were swelling, crusting and painful. Dentition was abnormal, and the patient had only 2 upper conical incisors. Routine investigation revealed that white cell count and C-reactive protein extremely elevated. Immunologic profile showed an abnormal distribution of lymphocyte subsets with decreased CD3+ T cells, CD8+ T cells and NK cells. Serum IgM level was slightly low. IgM antibodies to herpes simplex virus type 1 (HSV-1) were detected by serological testing. Based on the above-mentioned features, a diagnosis of anhidrotic ectodermal dysplasia with immunodeficiency and disseminated herpes simplex infection was confirmed. The patient was resolved favourahly after intravenous ganciclovir and antibiotics for 3 weeks without relapse of skin lesions.

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: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.
