Objective To detect the expressions of Numb and α-catenin in the gastric cancer and matched normal gastric mucosa,and to analyze their relationship with clinicopathological factors of gastric cancer and explore their roles in gastric carcinogenesis and progression.Methods Immunohistochemical method was used to detect the expressions of Numb and α-catenin in 109 cases of tumor specimens and 97 cases of matched normal gastric mucosa.The correlations between Numb,α-catenin and clinicopathological factors were analyzed.Results The positive rates of Numb and α-catenin in gastric cancer were significantly lower than those in normal gastric mucosa (60.6％ ∶ 100.0％,x2 =48.361,P =0.000;76.1％ ∶ 100.0％,x2 =26.480,P=0.000).The expression of Numb protein was correlated with Lauren type (x2 =17.018,P =0.000) and tubular adenocarcinoma differentiation (x2 =17.586,P =0.000).The expression of α-catenin protein was correlated with Borrmann type (x2 =6.700,P =0.035),Lauren type (x2 =11.098,P =0.001),tubular adenocarcinoma differentiation (x2 =8.203,P =0.017) and lymph node metastasis (x2 =6.402,P =0.011).The expressions of Numb and α-catenin were statistically correlated in 109 cases of gastric cancer (rk =0.184,P =0.028).Conclusion Compared with normal gastric mucosa,both Numb and α-catenin expressions are down-regulated and the two expressions are correlated in gastric cancer.Numb and α-catenin may be involved in the regulation of histological differentiation of gastric cancer by certain passages,Numb protein may be adjusted by α-catenin pathway which is involved in Wnt-β-catenin pathway,and thus plays an important role in promoting cell proliferation,invasion and metastasis in human gastric cancer.

Objective:Hyperoxia is a necessary therapy in some neonatal diseases, and long-term therapeutic hyperoxia may induce severe damaging effects on intestinal epithelial cells.The aim of this study was to investigate whether hyperoxia could promote the expression of ASK1 and P38 in intestinal epithelial cells through ROS.Methods:The human colon adenocarcinoma cell line Caco-2 cells were treated with different concentrations of H 2O 2(100 μmol/L, 200 μmol/L and 400 μmol/L)and 85% oxygen in vitro.The expression of ASK1 was detected by immunofluorescence, and the expression of P38 and p-P38 were detected by Western Blot and Real-time PCR. Results:With the increase of H 2O 2 concentration, the fluorescence intensity of ASK1 increased.The fluorescence intensity of ASK1 in the hyperoxia group was significantly stronger than that of the control group and the H 2O 2 groups.With the increase of H 2O 2 concentration(100 μmol/L、200 μmol/L、400 μmol/L), the expression of P38 protein(0.21±0.02, 0.28±0.13, 0.44±0.07)and p-P38 protein(0.09±0.02, 0.19±0.03, 0.37±0.07)gradually increased.The expression of P38 mRNA in 200 μmol/L and 400 μmol/L H 2O 2 groups(4.03±0.68、3.94±0.71)was significantly higher than that in 100 μmol/L H 2O 2 group(3.05±0.47)( P<0.01). The expressions of P38 protein, p-P38 protein and P38 mRNA in the hyperoxia group were significantly higher than those in the H 2O 2 group( P<0.01). Compared with the control group, the expressions of P38 protein, p-P38 protein and p38 mRNA in the hyperoxia group and H 2O 2 groups increased significantly( P<0.01). Conclusion:The expression of ASK1 and P38 in intestinal epithelial cells increased significantly under hyperoxia, which indicated that hyperoxia might activate ASK1 and thereby regulate the expression of downstream P38 through ROS, resulting in intestinal epithelial cells damage.

Objective To investigate the influence of different HBV DNA extraction methods with Micro-Nucleic-Releaser (MNR), polysaccharide deposition method and boiling method in real-time quantitative and provide reference data for clinical lab regarding the PCR kit selection. Methods Three different HBV DNA isolation methods including MNR, polysaccharide deposition method and boiling method were used to study the extraction efficiency and anti-interference ability when HBV DNA virus in lipemia, haemolysis or jaundice serum samples was detected with real-time PCR. The traditional HBV DNA isolation method of Hydroxybenzene-Chloroform was used as control method. Results The quantitative results and amplification efficiency differed among different extraction methods. Complete hemolytic sample brought biggest influence, modest hemolytic sample give minimal influence, whereas the lipemia and jaundice did not bring significant influence to detection. The MNR give the best amplification efficiency and quantitativereproducibility. The extraction efficiency of boiling method was lowest. The fluorescent efficiency of real-timePCR from Hydroxybenzene-Chloroform methods was better than other methods, but it suffered from losingHBV DNA. Conclusions Real-time PCR system of HBV DNA isolation by MNR can provide an accurate,highly sensitive, and rapid method to quantify Hepatitis B virus. It is suitable to use in clinical laboratory.
