AIM: To investigate the dose and time-effect relationship of 7 antimicrobial agents in experimental treatment of vibrio vulnificus infection in mice. METHODS: Vibrio vulnificus ( 6.0?10 11 CFU?L -1) was introduced intraperitoneally into the right abdominal cavity. After 1 h, 7 antimicrobial agents were given intraperitoneally using 5 dose levels respectively, and (were given intraperitoneally) using human therapeutic dose after 0.5, 1, 2, 3 h of infection, respectively. 7 antimicrobial agents were imipenem lcilastatin, chloramphenicol, doxycycline hydrochloride, netilmicin sulfate, cefoperazone sodium, piperacillin sodium, and levofloxacin lactate. The numbers of survival mice and the supermicrostructure change of organs were observed. RESULTS: With high dose of the seven agents, blood culture showed negative, and organ supermicrostructure injure recovered. 7 antimicrobial agents produced satisfactory therapeutic effect against experimental vibrio vulnificus infection using human therapeutic dose after 0.5～1 h of infection. Chloramphenicol, netilmicin sulfate, cefoperazone sodium and levofloxacin lactate had the better therapeutic effect after 2 h of infection, and weak effect after 3 h. Imipenem showed a weak effect. CONCLUSION: The treatments with these 7 antimicrobial agents early can obtain satisfactory therapeutic effect against experimental vibrio vulnificus infection in mice.

Objective To investigate the effects of hyperbaric oxygen (HBO) on homing of exogenous bone marrow mesenchymal stem cells (BMSCs) after traumatic brain injury (TBI) in rats. Methods BMSCs were isolated and cultured with Ficoll density gradient centrifuga-tion, and the surface markers (CD29, CD90, CD45, CD11b) of the third generation were identified with flow cytometry. The authenticated BM-SCs were processed by the cell membrane fluorescent probe CM-DiI before transplantation. Thirty-six Sprague-Dawley rats were divided in-to Sham group (n=6), TBI group (n=6), BMSCs group (n=12), HBO+BMSCs group (n=12). The number and locations of homing of tracing BMSCs were observed under fluorescent microscope after frozen sections, and the expression of stromal cell-derived factor 1 (SDF-1) and CXC chemokine receptor type 4 (CXCR4) proteins were detected with Western blotting one and three days after BMSCs transplantation. Re-sults The fluorescence-labeled BMSCs focused on the injured hemisphere, especially around the damaged brain tissue. The number of hom-ing was more in HBO+BMSCs group than in BMSCs group at the same time (P<0.01), and increased in both groups three days after trans-plantation compared with those of one day after transplantation (P<0.01). The expression of SDF-1 and CXCR4 protein were more in HBO+BMSCs group than in BMSCs group (P<0.05). Conclusion HBO can promote the exogenous BMSCs homing to damaged brain tissue in rats after traumatic brain injury, which is related to the enhancement of SDF-1/CXCR4 axis.
