Objective To evaluate the efficacy and safety of 10-day moxifloxacin,esomeprazole plus furazolidone triple therapy as first-line treatment to eradicate Helicobacter pylori (Hp)in comparison with the 14-day quadruple therapy containing esomeprazole,amoxicillin, clarithromycin and colloidal bismuth pectin. Methods A total of 1 26 cases of endoscopically confirmed Hp-positive chronic active gastritis or peptic ulcer were randomly assigned to the treatment group to receive esomeprazole,moxifloxacin plus furazolidone triple therapy for 1 0 days;or to the control group to receive esomeprazole, amoxicillin,clarithromycin,and colloidal bismuth pectin quadruple therapy for 14 days.Clinical efficacy and safety were evaluated after 4-week treatment.Results At the end of treatment,the Hp eradication rate was 89.4%in the treatment group, and 88.3% in the control group(P>0.05).The incidence of adverse reactions in the treatment group (16.7%)was significantly lower than that in the control group (36.7%)(P<0.05).Conclusions The 10-day moxifloxacin,esomeprazole plus furazolidone triple therapy is effective and well-tolerated as first-line treatment to eradicate Hp with samilar efficacy and fewer adverse reactions compared to the 14-day bismuth-based quadruple therapy.

Liposomes have made remarkable achievements as drug delivery vehicles in the clinic. Liposomal products mostly benefited from remote drug loading techniques that succeeded in amphipathic and/or ionizable drugs, but seemed impracticable for nonionizable and poorly water-soluble therapeutic agents, thereby impeding extensive promising drugs to hitchhike liposomal vehicles for disease therapy. In this study, a series of weak acid drug derivatives were designed by a simplistic one step synthesis, which could be remotely loaded into liposomes by pH gradient method. Cabazitaxel (CTX) weak acid derivatives were selected to evaluate regarding its safety profiles, pharmacodynamics, and pharmacokinetics. CTX weak acid derivative liposomes were superior to Jevtana® in terms of safety profiles, including systemic toxicity, hematological toxicity, and potential central nerve toxicity. Specifically, it was demonstrated that liposomes had capacity to weaken potential toxicity of CTX on cortex and hippocampus neurons. Significant advantages of CTX weak acid derivative-loaded liposomes were achieved in prostate cancer and metastatic cancer therapy resulting from higher safety and elevated tolerated doses.

Pure drug-assembled nanomedicines (PDANs) are currently under intensive investigation as promising nanoplatforms for cancer therapy. However, poor colloidal stability and less tumor-homing ability remain critical unresolved problems that impede their clinical translation. Herein, we report a core-matched nanoassembly of pyropheophorbide a (PPa) for photodynamic therapy (PDT). Pure PPa molecules are found to self-assemble into nanoparticles (NPs), and an amphiphilic PEG polymer (PPa-PEG
