The risk of bias was evaluated by the Cochrane Collaboration's tool and all of the studies had acceptable quality. The main outcomes included mortality, re-bleeding, received surgery rate, blood transfusion units and hospital stay time. These outcomes were estimated using odds ratios(OR) and mean difference with 95% confidence interval(CI). Rev Man 5.3.3 software and Stata 12.0 software were used for data analyses. RESULTS: Ten randomized controlled trials involving 1283 patients were included in this review; 678 subjects were in the proton pump inhibitors(PPI) group and the remaining 605 subjects were in the H2 receptor antagonists(H2RA) group. The meta-analysis results revealed that after successful endoscopic therapy, compared with H2 RA, PPI therapy had statistically significantly decreased the recurrent bleeding rate(OR = 0.36; 95%CI: 0.25-0.51) and receiving surgery rate(OR = 0.29; 95%CI: 0.09-0.96). There were no statistically significant differences in mortality(OR = 0.46; 95%CI: 0.17-1.23). However, significant heterogeneity was present in both the numbers of patients requiring blood transfusion after treatment [weighted mean difference(WMD),-0.70 unit; 95%CI:-1.64- 0.25] and the time that patients remained hospitalized [WMD,-0.77 d; 95%CI:-1.87- 0.34]. The Begg's test(P = 0.283) and Egger's test(P = 0.339) demonstrated that there was no publication bias in our meta-analysis.CONCLUSION: In patients with upper gastrointestinal bleeding after successful endoscopic therapy, compared with H2 RA, PPI may be a more effective therapy.展开更多

A literature search was conducted in PubMed, Medline, Embase, and Cochrane databases to include randomized controlled head-to-head comparative trials evaluating the efficacy of H2RAs or proton pump inhibitors in healing EE. Relative risk (RR) and 95% confidence interval (CI) were calculated under a random-effects model.RESULTS: RRs of cumulative healing rates for each comparison at 8 wk were: high dose vs standard dose H2RAs,1.17 (95%CI, 1.02-1.33); standard dose proton pump inhibitors vsstandard dose H2RAs, 1.59 (95%CI, 1.44-1.75);standard dose other proton pump inhibitors vs standard dose omeprazole, 1.06 (95%CI, 0.98-1.06). Proton pump inhibitors produced consistently greater healing rates than H2RAs of all doses across all grades of esophagitis, including patients refractory to H2RAs. Healing rates achieved with standard dose omeprazole were similar to those with other proton pump inhibitors in all grades of esophagitis.CONCLUSION: H2RAS are less effective for treating patients with erosive esophagitis, especially in those with severe forms of esophagitis. Standard dose proton pump inhibitors are significantly more effective than H2RAs in healing esophagitis of all grades. Proton pump inhibitors given at the recommended dose are equally effective for healing esophagitis.展开更多

METHODS: Ten volunteers without H pylori infection participated in this crossover study comparing lafutidine 10 mg with LPZ 30 mg. Intragastric pH was monitored for 6 h in all participants, and blood samples were collected from four randomly selected individuals after single-dose administration of each drug. RESULTS: The median intragastric pH was significantly higher in individuals who received lafutidine 10 mg than in those who received LPZ 30 mg 2, 3, 4, 5, and 6 h after administration. Maximal plasma drug concentration was reached more promptly with lafutidine 10 mg than with LPZ 30 mg. CONCLUSION: In H pylori-negative individuals, gastric acid secretion is more markedly inhibited by lafutidinethan by LPZ.展开更多

While this drug discovery strategy is extremely successful, the number of new chemical entities in the pharmaceutical pipeline is diminishing and complementary strategies are in need. A particularly attractive therapeutic strategy is to neutralize soluble signalling proteins using small molecules. Small molecule-based technologies have the potential to sufficiently alter the molecular topology of a given ligand and inhibit ligand/receptor interactions—effectively neutralizing the ligand’s signalling capacity. Recent technical advances in the field of structural biology have enabled the elucidation of ligand/receptor complexes at atomic resolution enabling a detailed appreciation of the molecular interactions governing ligand-mediated receptor activation. Exploiting molecular modeling techniques to study these signalling complexes allows for a paradigm shift from “receptorcentric” to “ligandcentric” screening strategies. Nerve growth factor (NGF) is a prototypical protein signalling ligand, which binds two receptors, TrkA and p75NTR. We first explore the molecular landscape governing the ligand/receptor interactions of NGF/TrkA and NGF/p75 structures. Next, we use the recently reported NGF neutralizing small-molecule, Y1036, as an affinity probe to determine residues in proximity to the pharmacological targeting domain of NGF and perform theoretical docking experiments to predict the residues which comprise distinct pharmacological targeting domains on the surface of NGF. Exploiting such strategies may facilitate “ligandcentric” drug discovery and could further the development of a trophic-factor-selective compound such as a BDNF-selective antagonist.展开更多
