Objective To investigate the molecular epidemiology of CRAB isolated from children in wuhan. Methods Forty non-repetitive strains of CRAB were collected from hospitalized children of emergency department, neonatal medicine, cardiothoracic surgery, bone surgery, respiratory medicine and renal medicine in Wuhan children's hospital during December 2008 and May 2009. MIC values were PFGE; KPC, IMP, GIM, SPM, SIM, OXA-23, VIM genes and integrase gene were amplified by PCR and then sequenced to confirm the genotypes.; Plasmid conjugation experiment was used to study the transfer method of bacterial resistance and southern blot hybridization was used to target the resistance genes. Results Susceptible rates of 40 strains to gentamicin, tobramycin, amikacin, ciprofloxacin, levofloxacin, trimoxazole were 20%, 5%, 93%, 93%, 95%, and 23% respectively. Eleven types of clone were detected by PFGE,including 29 strains of type A clone, 2 strains of type B clone, and 1 strain for each type of C to K clone. Eleven isolates produced both IMP-4 and OXA-23 carbapemase. Twenty-six isolates only possessed OXA-23 carbapemase. Thirty-six strains carried class Ⅰ integron. The results of southern blot hybridization showed that Intl, IMP-4 and OXA-23 type were located on chromosome. Conclusions Type A clone of CRAB is the most common. OXA-23 and IMP-4 type are the major acquired carbapemases, especially the OXA-23 is the most common type. The horizontal transmission of OXA-23 and IMP-4 gene mediated by Int1 and the spread of type A resistant clone is the major way of the spread of carbapenem-resistant Acinetobacter baumannii in the region.

Objective To investigate the distribution of acquired carbapenemases in carbapenemresistant strains of Klebsiella pneumoniae, and explore its role in epidemiology of nosocomial infection. Methods From November 2008 to March 2009, twenty clinical isolates of carbapenem-resistant Klebsiella pneumoniae were collected from children hospitalized in Wuhan children's hospital. MICs of antibiotics were tested by DNA of Klebsiella pneumoniae. Modified Hodge test was used to screen strains producing carbapenemases,combined imipenem(IPM)-EDTA , meropenem(MEM)- EDTA and ceftazidime(CAZ) - EDTA double-disk synergy test (DDST) were used to detect metallo-β-lactamase-producing. PCR amplification of the carbapenemase and integrase genes, and sequencing were performed. Plasmid conjugation transfer experiments and Southern hybridization were applied to study the mode of drug resistance transmission. Results Four types of Klebsiella pneumoniae were detected by PFGE, type A consisted of 5 strains, including 3 strains of type Al and 2 strains of type A2), type B (2 strains), type C (12strains) and type D (1 strain). Type A and C were the main drug resistant clones. Eight strains of Klebsiella pneumoniae carried both KPC-2 and IMP-4 genes, 10 strains carried IMP-4 gene, 2 strains carried KPC-2 gene. None of NDM-1 ,GIM, SPM, SIM, OXA-23, and VIM carbapenemase genes was detected in 20 isolates. All of 20 isolates carried lntl which were found to be located on bacterial chromosome by Southern blot. Conclusions KPC-2and IMP-4 genes are the major carbapenemase genes in Klebsiella pneumoniae isolated in Wuhan.Transmission of drug resistance is mainly through vertical transmission of type C resistant clone and horizontal transmission of Intl on bacteria chromosome.

Objective To explore ways to decrease peripheral vascular complications during parenteral nutrition through peripheral veins. Methods According to the support sequences of giving peripheral parenteral nutrition, ninty perioperative cases were randomly divided into low(20. 3 kPa·h-1 ),medium(27. 1 kPa·h-1 ) and high(33. 9 kPa·h-1 ) osmotic pressure rates(n=30 in each group). The infusion pump was used to control the rate of infusion. The total parenteral nutrient was infused through BD24G venous indwelling needles. The pain ratings at injection sites were evaluated after parenteral nutrition everyday,the incidences of phlebitis were observed three days later after removing the indwelling needles. ResultsUnder the low osmotic pressure,the pain was mild,while for the medium osmotic pressure,the pain became more obvious. The pain was aggravated obviously under high osmotic pressure. There were only two cases of over grade-II phlebitis under low osmotic pressure rate,9 cases under medium osmotic pressure rate and 14 cases under high osmotic pressure rate, in which a grade-Ⅲ phlebitis developed. Conclusion Decreasing the osmotic pressure rate through peripheral venous is an effective method to avoid or reduce the incidences of peripheral vascular complications with the peripheral parenteral nutrition support.

OBJECTIVETo study the anti-angiogenesis effect and toxicity of arsenic trioxide (As2O3) plus cinobufacin on transplanted human hepatocarcinoma in nude mice, and the acting mechanism of the treatment was explored as well.

METHODSHuman hepatocarcinoma was transplanted in nude mouse, and the modeled mice were divided at random into 4 groups, 8 in each group. They were treated respectively with normal saline (GA), 2.5 mg/kg As2O3 (GB), 5 mL/kg cinobufacin (GC) and 2.5 mg/kg As2O3 + 5 mL/kg cinobufacin (GD), by intraperitoneal injection for 21 days. The anti-tumor effects was evaluated by estimating general condition of nude mice, tumor size, microvessel density(MVD) level. Expressions of vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) in tumor, in tumor tissue of mice as well as pathology of tumor were detected by immunohistochemistry assay, optical microscope, transmission electron microscope (TEM), respectively. Moreover, blood routine and pathological examinations of liver and kidney were performed.

RESULTSThe tumor weight and volume were 0.65 +/- 0.25 g and 0.44 +/- 0.14 cm3 in GB, 0.70 +/- 0.27 g and 0.46 +/- 0.19 cm3 in GC, 0.42 +/- 0.16 g and 0.26 +/- 0.11 cm3 in GD, all significantly lower than those in GA (1.06 +/- 0.25 g and 0.67 +/- 0.17 cm3, P < 0.05). The coefficient of drug interaction (CDI) on tumor weight was 0.97 and that on tumor size was 0.86, all less than 1, showing the synergistic action between the two drugs. Expressions of VEGF and EGFR in tumor as well as the MVD were decreased in GB and GC, and the decreasing of these indices were even more significant in GD. Pathologic examination showed the growth of tumor in GB, GC and GD were all inhibited significantly. No obvious toxicity of the treatments to the hepatic, renal and hematopoietic systems in the nude mice was observed.

CONCLUSIONSAs2O3 and cinobufacini showed synergistic action in inhibiting human hepatocarcinoma in nude mice and the angiogenesis in tumor. Combined use of the two had no obvious toxicity to the hepatic, renal and hematopoietic systems.

BACKGROUND:There is no literature about the treatment according to the mechanism of cervical spine injury classification, especial y for the treatment of extension type cervical fracture/dislocation with merger cases of posterior composite structure damage, whether simple anterior approach can meet the needs of the treatment has no detailed elaboration. This article may analyze from the aspect of cervical spine injury mechanism. OBJECTIVE:To observe the short-term effect of anterior cervical Cage-assisted fusion combined with locking titanium plate internal fixation for the treatment of extension type cervical fracture. METHODS:A retrospective analysis was performed in 15 extension type cervical spine fracture dislocation patients treated with decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation from June 2006 to March 2011 in the Department of Orthopedics, Xianning Central Hospital, including 10 cases of single segment injury and treatment, and five cases of multiple segment injury and treatment. Japanese Orthopaedic Association score and the neck disability index were compared before and after treatment;the cervical flexion and height were measured according to the antersposterior X-ray film taken before fixation, 1 week after fixation and final fol ow-up.RESULTS AND CONCLUSION:The patients were fol owed-up for 8-37 months. One case had Cage mild sinking and shift, and there was no internal fixation breakage or loosening in al the patients. Transient pharyngeal discomfort was observed in 11 patients. Compared with the preoperation, the Japanese Orthopaedic Association score, neck dysfunction index, fusion segment cervical flexion and fusion segment intervertebral disc height were significantly improved at 1 week after fixation and final fol ow-up (P<0.05). There were no significant differences between 1 week after fixation and final fol ow-up (P>0.05). The short-term effect of decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation for the treatment of extension-type cervical fracture is good.
