The epidemic characteristics and genotype of Bacillus anthracis strains in Liaoning Province ,China was analyze in this study .Six Bacillus anthracis strains from 2001 to 2011 were studied with multiple‐locus variable‐number tandem repeat analysis (MLVA) .BioNumerics4 .0 software was used to analyze the DNA fingerprint of statistics ,and cluster analysis results were obtained .Clustering analysis found that the 6 strains could be divided into two genotypes .For anthrax outbreaks ,the ge‐netic markers of multiple‐locus variable‐number tandem repeat were highly similar .It's suggested that MLVA is quite useful for investigation of strain relatedness in regions of outbreaks .

Objective To compare the treatment effects between improved micro-laparoscopic hernia sac high ligation and traditional hernia sac high ligation.Methods Retrospective analysis was conducted.A total of 200 pediatric patients diagnosed with inguinal hernia in our hospital from 2013 to 2014,ranging in age from 8 months to 14 years,were enrolled and divided into observational group and control group (n=100) The two groups received improved-micro-laparoscopic hernia sac high ligation and traditional hernia sac high ligation respectively.We recorded intraoperative blood loss,operative incision length and operation time during the operation,and hospitalization time,pain time and total cost after the operation.Recurrence rate and complication were followed up for 6 months.Treatment effects were compared between these two groups.Results Smaller incision length,less blood loss and postoperative pain,shorter operative time and hospitalization time and lower recurrence rate were found in observational group and they were of statistical significance (P＜0.05).Conclusion Improved-micro-laparoscopic hernia sac high ligation for pediatric inguinal hernia shows better treatment effect,lower recurrence rate and better prognosis and it is an ideal approach.

Abstract: Our previous work revealed berberine can significantly enhance the susceptibility of fluconazole against fluconazole-resistant Candida albicans, which suggested that berberine has synergistic antifungal activity with fluconazole. Preliminary SAR of berberine needs to be studied for the possibility of investigating its target and SAR, improving its drug-likeness, and exploring new scaffold. In this work, 13-substitutited benzyl berberine derivatives and N-benzyl isoquinoline analogues were synthesized and characterized by 1H NMR and MS. Their synergetic activity with fluconazole against fluconazole-resistant Candida albicans was evaluated in vitro. The 13-substitutited benzyl berberine derivatives 1a-1e exhibited comparable activity to berberine, which suggested that the introduction of functional groups to C-13 can maintain its activity. The N-benzyl isoquinolines, which were designed as analogues of berberine with its D ring opened, exhibited lower activity than berberine. However, compound 2b, 2c, and 4b showed moderate activity, which indicated that berberine may be deconstructed to new scaffold with synergistic antifungal activity with fluconazole. The results of our research may be helpful to the SAR studies on its other biological activities.

OBJECTIVETo explore the clinical features and operative treatment of floating shoulder injuries.

METHODSThe clinical data of 25 patients with floating shoulder injuries that had been admitted to the hospital from July 2000 to May 2011 were retrospectively analyzed. There were 18 males and 7 females,wirh an average age of (36.2 +/- 2.3) years ranging from 17 to 56 years. The scapular neck fractures associated with clavicle fractures were in 21 cases and acromioclavicular joint dislocation in 4 cases. All cases were accompanied by associated injuries. Among of them, 7 cases were conservative treatment, 7 cases were fixed clavicle only, 11 cases were clavicle and scapular. All datum were rated according to Herscovici, Constant and Murley, Rowe rate system.

RESULTSAll patients were followed up for 4.6 years (range 11 months to 10 years). All fractures were healed except for 1 clavicle was delay healed. There were not infections and fixation fracture,2 of conservative treatment were dropping shoulder, 2 of 3 brachial plexus injuries were recovered 3 months later, 1 was 6 months. Suprascapular nerve injury was recoved 1 year later. Herscovici evaluation: 18 excellent, 5 good, 1 fair, 1 poor;Constant and Murley shoulder score: (83.2 +/- 5.7), pain score (12.1 + 2.5), activities of daily living score (17.2 +/- 3.2), range of motion score (32.1 +/- 3.5), strength score (18.5 +/- 2.1); Rowe evaluation: 18 excellent, 5 fair, 2 poor.
