Objective: This study investigates the effect of docetaxel + oxaliplatin + S-1 (DOS program) in treating advanced gastric cancer and surgical safety assessment. Methods: Fifty patients with advanced gastric cancer admitted to the Department of Gastrointestinal Surgery, The Affiliated Tumor Hospital of Xinjiang Medical University between January 2011 and May 2012 were enrolled in this study. These patients were randomized into the observation arm (n=25) and the control group (n=25). The observer group was administered three cycles of chemotherapy using a DOS program before surgical treatment, whereas the control group underwent surgery. Results: Compared with the control group, the clinical response rate (64.0%), D2 lymph node dissection rate (88.0% vs. 64.0%), and R0 resection rate (92.0%vs. 68.0%) in the observation group were significantly higher (P<0.05). Moreover, the number of postoperative lymph node metastasis in the observation group was significantly less than that in the control group (3.2±2.5 vs. 6.3±2.9, P<0.05). The operative time (230.5 min±45.6 min vs. 205.6 min±42.4 min) and intra-operative blood loss (425.5 mL ±115.4 mL vs. 210.6 mL±125.6 mL) of the two groups were sta-tistically significantly different (P<0.05). The incidence of postoperative complications and lymph node sweeping number of the two groups showed no significant difference (19.6 ±2.8 vs. 21.2 ±2.0, P>0.05). The patients exhibited good tolerance to chemotherapy, with bone marrow suppression and gastrointestinal reactions as the main adverse effects. Conclusion:The DOS program is a highly efficient, advanced gastric cancer neoadjuvant chemotherapy. The program can improve patient survival and has good patient tolerance and compliance, good peri-operative safety, high R0 resection rate, and low postoperative lymph node metastasis rate.

Objective To identify the imbalance of T cell-specific transcription factors T-bet/GATA-3,and to explore the modulation with dexamethasone and imiquimod in CD4+T cells from ovalbumin (OVA)sensitized mice.Methods CD4+T cells were obtained fromsingled-cell suspension of spleen(after lysis of RBC).ELISA assay was used to detect the concentrations of IL-4,IL-5 and IFN-γin superna tants and cell pellets,and the expression of T-bet and GATA-3 was detected by Western blot.Resuits In the control group,tIle low levels of IFN-γ were detected in the supernatants during 24 h.In OVA treatment group,the concentrations of IL-4,IL-5 were increased significantly,and the concentrations of IFN-γ were always low in the supernatants.In the dexamethasone treatment group,the concentrations of IFN-γ,IL-4 and IL-5 were all low in the supernatants during 24 h.In the imiquimod treatment group,the concentrations of IFN-γ were increased significantly,and the concentrations of IL-4 and IL-5 were decreased in the super natants.It worked at 6 h,and achieved the peak at 12 h,lasted over 24 h.In the control group,the expres sions of T-bet and GATA-3 were detected in CD4+T cells during 24 h.In OVA treatment group,the expressions of T-bet were decreased,and that of GATA-3 were increased rapidly in CD4+T cells.In dexam ethasone treatment group,the expressions of T-bet were always low in CD4+T cells,and that ofGATA-3 were no change during 24 h.In imiquimod treatment group,the expressions of T-bet were increased,andthat of GATA-3 were decreased in CD4+T cells.The protein expressions worked at 6 h.and achieved the peak at 12 h,lasted over 24 h.Conclusion The imbalance T cell-specific transcription factors T-bet/GA-TA-3 contributes to both high expression of GATA-3 and low expression of T-bet in CD4+T cells from OVA sensitized mice.Dexamethasone treatment inhibits the expression of T-bet in CD4+T cells and has no func tion in GATA-3.Imiquimod treatment modulates key master switches GATA-3 and T-bet that results in com mitting T helper cell to a TH 1 phenotype and imiquimod may play a key role in the regulation of TH2 cytokine responses in asthma.

Objective To study the growth inhibition,apoptosis induction effects of cinobufagin(CB)on human osteosarcoma(OS) cell line U2OS,MG63 and SaO2 in vitro and the underlying mechanism of action of cinobufagin in OS cells.Methods Cell viability was assessed by MTT assay.Cell-cycle status,apoptosis-inducing effects were evaluated by flow cytometry,fluorescent staining and DNA fragmentation assays.Inhibitors of apoptosis proteins (IAPs) and Bcl-2 family proteins including Bax,cleaved-PARP,xIAP,cIAP-1,survivin and p65 were tested by Western blot.Results MTT assay showed that CB could inhibited the growth of U2OS,MG63 and SaO2 cells in a dose-and time-dependent manner.The 48 h IC50 of CB on U2OS,MG63 and SaO2 cells were (104.83± 16.96) nmol/L,(47.07±7.5) nmol/L,and (136.72±10.08) nmol/L respectively.The induction of G2/M cell-cycle arrest was seen in the cells treated with CB.After cells were cultured for 12 h in the presence of 100 nmol/L CB,the percentages of cells in the G0/G1 phase were decreased,while G2/M phase were increased in U2OS,MG63 and SaOS2 cells,respectively.The results showed CB inhibited the proliferation of osteosarcoma cells through blocking the cell cycle in G2/M phase.Induction of apoptosis was confirmed by Hoechst 33258 and Annexin V/PI staining.After treating with 100 nmol/L CB for 48 h,the extents of apoptosis were 33.6％±6.4％,36.4％±7.8％ and 29.3％±5.1％,respectively.These results indicate that the anti-tumor activity of cinobufagin in osteosarcoma cells was due to a G2/M cell cycle arrest and apoptosis inducing effect.Western blot showed that CB could induce the apoptosis related family proteins Bax,cleaved-PARP up-regulation,xIAP,cIAP-1,survivin and p65 downregulation in OS cells.Conclusion CB can inhibit the cell viability and induce G2/M cell cycle arrest and apoptosis in U2OS,MG63 and SaO2 cells.The apoptosis-inducing effect of CB is confirmed by the regulation of apoptosis related proteins IAPs and Bcl-2 in vitro.

Protein tyrosine phosphatase (PTP) 1B is a potential target for the treatment of diabetes and obesity. We have previously identified the benzoyl sulfathiazole derivative II as a non-competitive PTP1B inhibitor with in vivo insulin sensitizing effects. Preliminary SAR study on this compound series has been carried out herein, and thirteen new compounds have been designed and synthesized. Among them, compound 10 exhibited potent inhibition against human recombinant PTP1B with the IC50 value of 3.97 micromol x L(-1), and is comparable to that of compound II.

A novel series of benzyl urea analogues based on the structural modification of sorafenib were synthesized. Their in vitro antitumor activities against MX-1, HepG2, Ketr3 and HT-29 were evaluated using the standard MTT assay. While several target compounds showed inhibitory activity against multiple cancer cell lines, compound 9 was of particular interest, demonstrating IC50 values (5.69-13.6 micromol x L(-1)) comparable to those of sorafenib. Furthermore, compounds 20 and 23 showed more potent inhibitory activity against HT-29 and MX-1 when compared to sorafenib. In particular, compound 20 bearing the N-3-pyridyl moiety not only exhibited greater inhibitory activity against HT-29 cell line (IC50 3.82 micromol x L(-1)), but also had improved solubility at pH 7.2, is worthy of further investigation as a lead to identify novel antitumor agents.

Objective To summarize the diagnosis,treatment and prevention of dysuria within 6 months after the suprapubic transvesical prostatectomy. Methods Twenty-four cases were retrospectively reviewed,including the data on the diagnosis, treatment and prognosis. Results Twenty-one of the 24 cases had received surgery. There were 9 cases with bladder neck stricture,9 cases with posterior urethra stricture and 3 cases with of remnant glands. Nine cases received transurethral bladder neck incision, 9 received open surgery ( bladder neck,posterior urethral incision) and 3 received transurethral resection of the prostate (TURP) plus bladder neck incision. The other 3 diagnosed as detrusor weakness were conservatively treated by indwelling catheter and they were improved one months later. None of these patients was readmitted into hospital for dysuria within 6 months after treatment. Conclusion The recurrence of dysuria post prostatectomy mostly ( 75% ) occurred within 6 months after surgery. A majority of these patients need a second surgery. To avoid a second surgery for postoperative dysuria, much attention should be paid to the operating technique and postoperative management.

Purpose To explore the expression of FLi-1,h-caldesmon and collagen Ⅳ in glomus tumor and possible relationship between different histological types and clinical-pathological characteristics.Methods Immunohistochemistry of EnVision method was used to detect the expression of FLi-1,h-caldesmon and collagen Ⅳ in 35 cases of glomus tumor under microscope,and the relationship between different histological types and clinical-pathological characteristics was analyzed.Results The pathological morphology of tumor cells was round or polygonal,patchy distribution in blood vessels or arranged in a ring around the blood vessels.The tumor cell boundary was clear and the shape was regular,gradual transition between tumor cells and spindle smooth muscle cells was sometimes visible.The positive rate of FLi-1,h-caldesmon and collagen Ⅳ in 35 cases of glomus tumor were 58.6％,97.1％ and 100％ respectively.Different histological types of glomus tumors had no correlation with the sex of patient and the size of tumor,but had correlation with the age of patient.Vimentin and SMA were positive for glomus tumors by immunohistochemistry in 35 cases.CD34 was positive in 2 cases.Desmin positive was found in 1 case.EMA,S-100,CgA,CD68 and CD99 were negative.Conclusion h-caldesmon and collagen Ⅳ are the markers for glomus tumor diagnosis,and FLi-1 can serve as a good auxiliary reference marker.

OBJECTIVETo investigate the expression profile of interleuki-1β (IL-1β) in rat myocardium at different time points during hypoxia/reoxygenation(H/R)transition.

METHODSThe isolated Langendorff perfused rat heart model was established.Forty SD rats were randomly divided into sham group (A group) and hypoxia/reoxygenation group (H/R group). The H/R group rats were subdivided into H/R 0.5 h group(B group), H/R 1 h group(C group), H/R 2 h group(D group)according to reoxygenation time. The left ventricular development pressure(LVDP), maximal rates of increase/decrease of the left ventricular pressure(±dp/dtmax) were continuously recorded. The concentration of interleukin-1β(IL-lβ) and creatine kinase-MB (CK-MB) in myocardium was measured by ELISA. The mRNA expression of IL-lβ in myocardium was determined by RT-PCR. Microstructure of myocardium was observed under light microscopy.

RESULTSThe value of LVDP and ±dp/dtmax in hypoxia/reoxygenation group rat were significantly lower than that in sham group(P < 0.05). The expression of IL-lβ and CK-MB at protein level and the expression of IL-1β at mRNA level in hypoxia /reoxygenation group were higher than that in sham group(P < 0. 05). There were significant differences of the above parameters among H/R 0.5 h, 1 h, 2 h group(P <0.05). The concentration of IL-1β and CK-MB, the mRNA expression of IL-1β were higher in H/R 2 h group than that of other groups(P < 0.05).

CONCLUSIONThe high expression of IL-Iβ in myocardium after myocardial hypoxia /reoxygenation in rats might lead to. ischemia/reperfusion injury.
