Clinical effects of different therapeutic regimens for Helicobacter pylori infection in children / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the clinical effects of sequential therapy, triple therapy, sequential therapy combined with Lactobacillus, and triple therapy combined with Lactobacillus in the eradication of Helicobacter pylori (H.pylori) infection in children.</p><p><b>METHODS</b>A total of 416 children with H.pylori infection were randomly assigned to sequential group (102 children), triple group (100 children), sequential-Lactobacillus group (109 children), and triple-Lactobacillus group (105 children). The clinical outcome, H.pylori eradication rate, cost-effect ratio, and incidence of adverse events were compared between the four groups.</p><p><b>RESULTS</b>The sequential-Lactobacillus and triple-Lactobacillus groups had significantly better clinical outcomes than the sequential group and the triple group (P<0.05). The sequential-Lactobacillus group had the highest marked response rate, followed by the triple-Lactobacillus group. The triple group had the lowest marked response rate. The sequential-Lactobacillus group also had the highest H.pylori eradication rate, followed by the triple-Lactobacillus group. The triple group had the lowest H.pylori eradication rate (P<0.05). The sequential group had the lowest cost-effect ratio, followed by the sequential-Lactobacillus group. The triple group had the highest cost-effect ratio (P<0.01). The sequential-Lactobacillus group had the lowest incidence rate of adverse events, followed by the triple-Lactobacillus group. The triple group had the highest incidence rate.</p><p><b>CONCLUSIONS</b>Sequential therapy combined with Lactobacillus seems to be the best regimen for the eradication of H.pylori infection in children.</p>

Anti-HIV-1 activities of extracts and phenolics from Smilax China l.

Four extracts [EtOH, CHCl[3], EtOAc, and BuOH] and five phenolics [dihydrokaempferol [1], resveratrol [2], kaempferol-7-O-beta-D-glucoside [3], dihydrokaempferol-3-O-alpha-L-rhamnoside [4], oxyresveratrol [5]] from Smilax china L. was evaluated for anti-HIV-1 activities and cytotoxicity activities in vitro. All these extracts and phenolics showed lower or no cytotoxicity at a concentration ranged from 0.8 microg/mL to 100 microg/mL, but some showed potential anti-HIV-1 activities, that is, BuOH extract and compound 2 showed higher anti-HIV-1 activities than other extracts and compounds in the tested concentrations. EtOAc extract and compound 1 and 3 showed moderate anti-HIV-1 activities at a concentration higher than 4 microg/mL. In the end, the structure-activity relationship of four extracts and five phenolics was discussed.
