Objective To investigate the interrelationship between Golgi phosphoprotein 3 ( GOLPH3 ) expression with vasculoar endothelial growth factor( VEGF) expression in the progression of human gastric cancer by detecting the expression level of GOLPH3 and VEGF. Methods Immunohistochemistry ( IHC) was used to detect the ex-pression of GOLPH3 and VEGF in 55 cases of gastric cancerous and carcinoma-adjacent tissues. Pearson correlation analysis was used to discuss the association between GOLPH3 expression with VEGF expression. Results The im-munohistochemical detection showed that the positive expression rates of GOLPH3 and VEGF were 67. 27%, 58. 18% respectively, which were significantly higher than the positive expression rates in carcinoma-adjacent tis-sues ( P<0. 05 ) . A statistical analysis revealed that the positive expression rate of GOLPH3 and VEGF in the gas-tric cancer tissues were strongly correlated with depth of invasion ( P<0. 05 ) , distant metastasis ( P<0. 01 ) and TNM stages (P<0. 01), whereas it did not significantly correlate with age or gender or size of tumor. Compared with the negative for the GOLPH3 expression, the VEGF expression in gastric cancer tissues positive for the GOL-PH3 expression was significantly higher. The protein level of GOLPH3 expression was positively correlated with VEGF expression (r=0. 508,P<0. 01). Conclusion GOLPH3 overexpression may regulate gastric angiogenesis by upregulating the expression of VEGF, which affects the invasion and metastasis of gastric cancer.

Objective To determine the expression of metastasis-associated gene 2 ( MTA2 ) and p53 in colorectal cancer and non-cancerous mucosa, analyze their relationship with clinicopathological parameters, and discuss the clinical significance. Methods 120 colorectal neoplasm patients' cancer tissues and clinical information were col-lected from the first affiliated hospital of Anhui medical university. 30 patients of them were chosen to collect non-cancerous mucosa which was 5 cm away from the tumor. Immunohistochemistry staining was used to detect the ex-pression of MTA2 and p53. According to the clinicopathological parameters, the positive and negative expression of MTA2, p53 were counted each group, discussed the relationship between positive expression and clinicopathologi-cal parameters by SPSS 19.0 . Results The immunohistochemistry showed that the positive expression rate of MTA2 was 59.16%, and the positive expression rate of p53 was 61.67%. The expression of MTA2 and p53 in colorectal cancer were significantly higher than non-cancerous mucosa ( P<0.05 ) . The MTA2 expression was positively cor-related with the depth of invasion, lymphatic metastasis, distant metastasis and TNM stages (P<0.05). The p53 protein expression was positively correlated with depth of invasion and lymphatic metastasis ( P<0.05 ) . Conclu-sion MTA2 could be used as a new clinical biomarker and therapeutic target for colorectal cancer probably, which might be more effective than p53 .

Objective: To investigate the apoptotic effects and its mechanisms on K562 cells caused by Interferon-alpha (INF-?) and Cytarabine (Ara-C). Methods: The variation of both morphology and inhibitory rate of K562 cells was observed in culture medium with IFN-? and various concentrations of Ara-C at different time in vitro. The variation of telomerase activity and P53 protein expression were detected before and after apoptosis occurred. Results: INF-? and Ara-C used concurrently could cause apoptosis and inhibit the growth of K562 cells as well as decrease the telomerase activity and increase P53 protein expression significantly. All these processes showed both in time- and dose-dependent manner. Conclusions: INF-? and Ara-C used concurrently can inhibit the growth of K562 cells and induce apoptosis, inhibiting the telomerase activity and increasing the expression of P53 protein may be one of the most important mechanisms.

Objective To investigate the use of PLR induced VTI changes combined with P(cv-a)CO2 in sepsis shock early fluid resuscitation. Methods 54 patients with sepsis shock admitted in Chancheng district central hospital from March 2016 to May 2017 were randomly divided into the treatment group (n=26) and the control group (n=28). The treatment group were monitored by the PLR induced VTI changes combined with P(cv-a)CO2, while the control group were monitored by CVP. The changes of 6 h, 12 h, 24 h, CVP, BNP and LAC levels, the time of vasoactive drugs, the time of mechanical ventilation, ICU hospitalization time and mortality were compared between the two groups. Results There were no statistic difference in fluid infusion within 6h, CVP, BNP, and LAC levels in the two groups; Fluid infusion within 12 h and 24 h, CVP and BNP in the treatment group were lower than those in the control group (P<0.05); the two groups for the treatment of 12 h,24 h plasma, LAC levels were no significant difference; The application time of vasoactive drugs, the time of mechanical ventilation and the length of hospitalization in ICU in the treatment group were shorter than those in the control group (P<0.05); The 28 day mortality was not statistically different between the two groups. Conclusion PLR induced VTI changes combined with P (cv-a) CO2 in septic shock early fluid resuscitation monitoring is superior to CVP, which has the important research significance.

AIM: To observe the effects of dexamethasone on the expression of toll-like receptor 4(TLR4)and the activation of NF-?B of dendritic cells(DC),and investigate the mechanism of dexamethasone suppressing differentiation,maturation,and function of DC.METHODS: DC generated from C57BL/6 murine bone marrow cells were induced by GM-CSF and IL-4.Dexamethasone was added in the DC's culture system,the cells were analyzed by flow cytometry(FCM) to determine the expression of TLR4 & CD11c,and by electrophoretic mobility shift assay(EMSA) to verify the activation of transcription factor NF-?B of DC.RESULTS: Dexamethasone could suppress the expression of CD11c and the activation of NF-?B with a dose-effect relationship in DC,but it could not suppress the expression of TLR4 of DC.CONCLUSION: The mechanism of dexamethasone involved in inhibition of differentiation,maturation,and function of DC is perhaps related to suppression of NF-?B activation.

Thymopentin (TP5) and bursopentin (BP5) are both immunopotentiators. To explore whether the TP5-BP5 fusion peptide (TBP5) has adjuvant activity or not, we cloned the TBP5 gene and confirmed that the TBP5 gene in a recombinant prokaryotic expression plasmid was successfully expressed in Escherichia coli BL21. TBP5 significantly promoted the proliferation of thymic and splenic lymphocytes of mice. The potential adjuvant activity of the TBP5 was examined in mice by coinjecting TBP5 and H9N2 avian influenza virus (AIV) inactivated vaccine. HI antibody titers, HA antibodies and cytokines levels (IL-4 and IFN-γ) were determined. We found that TBP5 markedly elevated serum HI titers and HA antibody levels, induced the secretion of both IL-4 and IFN-γ cytokines. Furthermore, virus challenge experiments confirmed that TBP5 contributed to inhibition replication of the virus [H9N2 AIV (A/chicken/Jiangsu/NJ07/05)] from mouse lungs. Altogether, these findings suggest that TBP5 may be an effective adjuvant for avian vaccine and that this study provides a reference for further research on new vaccine adjuvants.

Objective To compare coronary artery abnormality between patients with silent myocardial ischemia (SMI)and pa-tients with symptomatic myocardial ischemia using coronary artery CT angiography.Methods Forty-three patients with SMI and 45 patients with symptomatic myocardial ischemia were collected and underwent coronary CT angiography using 128-slices spiral CT scanner,respectively.Results Stenosis of coronary artery detected in 23 patients with SMI was (23/43,53.49%),and stenosis in 21 patients with symptomatic myocardial ischemia was (21/45,46.67%).The difference of incidence had no statistical significance, but the degree of stenosis and the number of stenosis vessel had statistical significance(P <0.05).The number of atherosclerotic plaque of coronary artery detected in patients with symptomatic myocardial ischemia was significantly more than that in patients with SMI(P <0.05).Conclusion There are no significant difference in the incidence of coronary stenosis between the patients with SMI and patients with symptomatic myocardial ischemia.However,the degree of stenosis and incidence of atherosclerotic plaque are sig-nificant different.

Objective To explore the characteristics of intestinal Microbiota in T2DM patients by two molecular fingerprint technologies,and investigate the correlation of intestinal microbiota and T2DM,and evaluate the application value of two fin-gerprint technologies.Methods Fecal samples of 8 healthy groups and 7 diabetes patients were collected.Then the total DNA of gut microbiota was extracted.Through the analysis of products by two molecular fingerprints of ERIC-PCR and DGGE-PCR,ecological characteristics of diversity and similarity of gut microbiota were obtained in healthy groups and dia-betes patients.Results Compared to healthy groups,the number of bands and Shannon-Wiener index of gut microbiota in di-abetes patients was decreased but no statistical significance.The similarity in patients group was declining(P <0.05),and the construction of gut microbiota was inclined to differ.Two fingerprint technologies of ERIC and DGGE could directly re-flect the diversity of gut microbiota and were the modern molecular biological techniques without depending on cultivation. ERIC was simple and convenient,had a better reflection of microbial diversity,but gel band cutting and regarded asa proper approach with higher diffraction efficiency and excellent repetition to studysequencing couldn’t be performed since there were more influencing factors on the experiment.DGGE could better reflect the ecological characteristics such as microbial diversity and similarity,and selecting bands,gel band cutting and sequencing could be done.Conclusion The composition and construction of gut microbiota in diabetes patients were changed,which suggests the occurrence of the disease had the correlation with gut microbiota.ERIC and DGGE is regarded as a proper approach with higher diffraction efficiency and ex-cellent repetition to study intestinal microbiota,but also gel band cutting,sequencing,bacteria identification can be performed by DGGE,both can be used in combination.
