Objective To study whether Helicobacter pylori CagA protein can control gastrin gene expression and the detailed mechanism. Methods First, pcDNA3. 1ZEO (-)/cagA7 was transfected into gastric cancer cell lines AGS and SGC-7901 cells. At the same time, culturing the Helicobacter pylori NCTC11637 and infecting AGS and SGC-7901 cells with it. Next, in the infected and transfecled AGS and SGC-7901 cells, respectively adding the JAK2 signaling pathway inhibitor AG490 and the ERK signaling pathway inhibitor U0126 to inhibit the two signaling pathway. Untreated gastric cancer cells and empty vector transfected cells as the control. Using real-time fluorescence quantitative PCR to detect the levels of gastrin mRNA in transfected and infected cells. Results After AGS and SGC-7901 cells were transfected with pcDNA3. lZE0(-)/cagA7 and infected with NCTC11637, the results showed that the expression of gastrin mRNA increased significantly (P < 0. 05) in transfected and infected cells as compared with the control group, but after adding the inhibitor AG490 and U0126 respectively, the expression of gastrin mRNA decreased significantly(P<0.05). Conclution These results suggest that CagA may up-regulate the expression of the gastrin gene, and CagA is one of the important proteins in regulating gastrin gene expression. The ERK/MAPK and JAK/STAT signaling pathways may be involved in controlling of gastrin gene expression by CagA.

An in vitro detection method of the gastrointestinal absorption of Pilose Antler protein was established for mixed protein activity. Five bands of protein with molecular weight of 17.8-160 kD derived from the Pilose Antler were extracted and sufficiently labeled with FITC (FITC-PE). The stability and variation of FITC-PE in gastrointestinal circumstances were detected by native polyacrylamide gel electrophoresis and confocal laser scanning microscope. Results showed that the main component of FITC-PE kept invariant after being reacted with artificial gastric fluid and artificial intestinal fluid. The fluorescence signal was detected 20 min after administration in the valgus intestinal purse experiment, and three kinds of protein, with molecular weight of 45, 25, and 17.8 kD, were detected in the mixture of absorbent protein. The research laid the foundation for the further in vivo study of Pilose Antler protein. Meanwhile, it would be an in vitro screening method for the absorption, distribution and metabolism of mixed protein from traditional Chinese medicine.

AIM: To investigate the possible role of nuclear transcription factor kappa B (NF-?B), Bcl-2, Bax and caspase-3 in etodolac-induced apoptosis of liver tumor SMMC7721 cell line. METHODS: Cell apoptosis was determined by flow cytometry analysis with PI staining and DNA laddering. Expression of Bcl-2 and Bax protein was measured by Western blotting. Caspase-3 activity was evaluated by active caspase-3 apoptosis kit with flow cytometry. NF-?B activation was detected by ELISA-based TransAM~(TM) NF-?B p65/p50 kit. RESULTS: Etodolac, a selective COX-2 inhibitor, stimulated apoptosis in liver tumor SMMC7721 cell line significantly. Flow cytometry showed that the apoptotic rate was 16.3%?3.1%, 19.9%?3.6%, 22.9%?3.2%, 31.2%?3.3% with different concentrations of etodolac (0.25, 0.50, 1.0 or 2.0 mmol/L), while the apoptotic peak did not appear in the control group (0 mmol/L) (P

Objective To investigate the effect of Rho kinase inhibitor,fasudil,on pulmonary fibrosis induced by paraquat in rats in order to elucidate the underlying mechanisms.Methods A total of 72 SpragueDawley male rats of specific pathogen free (SPF) were randomly (random number) divided into four groups:the normal control group (NS group,n =18),fasudil control group (FS control group,n =18),paraquat poisoning group (PQ poisoning group,n =18) and fasudil intervention group (FS intervention group,n =18).On days 7,14,28 after paraquat exposure,six rats were respectively selected from each group.These rats were anesthetized and sacrificed immediately,and their lung tissues were collected.The hydroxyproline (HYP) in the lung tissue was detected by using alkaline hydrolysis.The expressions of type Ⅰ,Ⅲ collagen protein,connective tissue growth factor (CTGF) and ROCK1 mRNA in Rho/ROCK signaling pathway were assayed by using the real-time quantitative PCR (RT-PCR),and the levels of type Ⅰ,Ⅲ collagen protein,connective tissue growth factor (CTGF) and Rho / ROCK signaling pathway ROCK1 protein were measured by using Western blotting.The pathological changes of lung tissue were observed under light microscope.Results There were no significant differences in the observed biomarkers between FS control group and NS group (P > 0.05).While in PQ poisoning group and FS intervention group on days 7,14,28 (all P < 0.05),the amount of HYP increased obviously (P < 0.05),the expressions of type Ⅰ,Ⅲ collagen protein,CTGF,ROCK1 mRNA and protein levels were increased significantly (P < 0.05).Compared with the PQ poisoning group,the amount of HYP decreased significantly,and the expressions of type Ⅰ,Ⅲ collagen protein,CTGF,ROCK1 mRNA and protein levels were decreased significantly in FS intervention group on days 7,14,28 (all P < 0.05).The pathological changes of lung tissue revealed that the degree of pulmonary fibrosis in the PQ poisoning group were most serious on 28 d after paraquat exposure,and the degree of pulmonary fibrosis were lessened in FS intervention group on days 7,14,28.Conclusions ROCK inhibitor,fasudil,has obvious therapeutic effects on paraquat-induced lung fibrosis,by regulating Rho / ROCK signaling pathway with downregulated expression of CTGF,and decrease in the levels of type Ⅰ,Ⅲ collagen protein,thus reducing protein deposition.

Objective To investigate the effects of blocking gastrin receptor on the proliferation,apoptosis and expression of key proteins in the related pathway in gastric cancer cell lines.Methods In the experimental group,the gastric cancer cell lines SGC-7901 and AGS cells were treated with 5 mmol/L proglumide,a kind of a gastrin receptor antagonist.And the normal cultured gastric cancer cells SGC-7901 and AGS were used in control group.The growth of each group was detected by MTT assay;the cell growth curve was drawn by flow cytometry;the cell cycle of each group was detected by flow cytometry.Annexin V-FITC/PI double staining was used to detect the cell growth of apoptosis.The relative mRNA expression of β-catenin,nuclear factor-P65,mammalian target of rapamycin and glycogen synthase kinase 3 beta in Wnt,NF-κB and PI3K-AKT-MTOR pathways were detected by RT-qPCR.The expression of β-catenin protein was detected by Western blotting.Results After treatment with proglumide,the growth of the cells in the experimental group was lower than that in the control group;and the proportion of S phase cells in the cell cycle was also lower than that in the control group,but the proportion of cells in G0/G1 phase was higher than that in the control group(P<0.05).The percentage of apoptotic cells was also increased after treatment with proglumide(P<0.05).Furthermore,proglumide treatment significantly reduced the expression of β-catenin at both mRNA and protein levels(P<0.05).Conclusion Blocking gastrin receptor can down-regulate the expression of β-catenin,inhibit the cell proliferation and promote the cell apoptosis in gastric cancer cells.

Patients with decompensated cirrhosis often have varying degrees of portal hypertension, and when portal pressure reaches a certain threshold, various clinical complications may occur and even threaten patients′ lives. Therefore, portal pressure assessment is important for the clinical management and prognosis of such patients. Due to the anatomical characteristics of the portal vein, it is difficult to measure portal pressure directly. At present, hepatic venous pressure gradient is used to replace portal pressure in China and foreign countries. However, the measurement of hepatic venous pressure gradient is an interventional procedure and is difficult to perform in clinical practice. Therefore, noninvasive assessment of portal hypertension has become a research hotspot. This article reviews the research advances in the roles of serum markers, ultrasound elastography, computed tomography, and magnetic resonance imaging/magnetic resonance elastography in noninvasive assessment of portal hypertension.
