Introduction: Helicobacter pylori eradication remains a problematic issue. We are in an urgent need for finding a treatment regimen that achieves eradication at a low cost and less side effect. Recent published results showing a high rate of resistance and with clarithromycin-based treatment regimens. The aim of the study was to compare moxifloxacin therapy and classic clarithromycin triple therapy in H. pylori eradication. Methods: This was a pilot study that enrolled 60 patients with helicobacter pylori associated gastritis. Diagnosis was done by assessment of H. pylori Ag in the stool. The patients were randomly assigned to receive either moxifloxacin based therapy (Group A), or clarithromycin based therapy (Group B) for two weeks. We stopped the treatment for another two weeks then reevaluation for cure was done. Results: 90 % of patients had negative H. pylori Ag in the stool after 2 weeks of stoppage of the treatment in group A versus 66.7 % in Group B. None of the patients in both groups had major side effects. Conclusion: Moxifloxacin-based therapy showed higher eradication power and less resistance when compared to clarithromycin triple therapy.

Based on transferring energy from multiple pump beams into one Stokes beam using Brillouin amplification, a serial coherent laser beam combination scheme is presented, which has many advantages, such as, simple structure, low cost, ease of adjustment, higher load capability, scalable easily, etc. Furthermore, it has been demonstrated that the combination of several beams using this method is theoretically possible. But in practice, the amplification of high power Stokes beam is a key problem to solve. In this paper, the amplification of Stokes beam whose power is higher than the pump beam is first studied and proved experimentally. Coupling the two laser beams by this method is proved experimentally, and the coupling efficiency reaches more than 80%. Then the feasibility of multiple beams combination based on Brillouin amplification is analyzed and tested theoretically.
