Objective To investigate the trend of omtibacterial resistance rate of Acinetobater baumannii in our hospital from Jan.2000 to Jun.2005,and for the guidance of rational use of antibacterials.Methods A.baumannii strain was isolated and tested by K-B method from clinical samples and antibiotic resistance was analyzed and studied retrospectively.Results There was an elevated tendency of the resistance rates to common antibacterial in A baumanii for past six years. The resistance rate to imipenem was the lowest (3.6%) and to amikacin, cefoperazone/sulbactam was 29.5%-77.4%.Conclusion The resistance rates to common the antibacterial in A.baumanii are high and the resistance pattern is wide. It is important to select antibiotics according to the antibiotics sensitivity in vitro.

OBJECTIVE:To screen and analyze the ?-lactamases-resistant genes in imipenem-resistant pseudomonas aeruginosa (IMPRPa). METHODS: ?-lactamases-resistant genes including IMP,VIM and OprD2 in 60 clinically isolated IMPRPa strains were detected by polymerase chain reaction (PCR),and sequence analysis was performed on the PCR amplified products of some of IMP and VIM genes. RESULTS: Of the 60 IMPRPa strains,?-lactamases-resistant positive genes were as follows: IMP gene was positive in 7 strains,VIM gene was positive in 18 strains,and both IMP and VIM genes were positive in 3 strains. Sequencing of the PCR products of IMP and VIM genes were IMP-1 and VIM-2 types,and OprD2 gene deletion was noted in 29 strains. CONCLUSION: OprD2 protein channel deletion and metal-producing ?-lactamases are the chief mechanisms for the resistance of IMPRPa to imipenem.

OBJECTIVE:To investigate the change in drug resistance of pseudomonas aeruginosa to imipenem bewteen Jan.2000and Jun.2005in the hospital where the authors work in order to provide the reference for rational choice of antibac-terials in clinic.METHODS:158strains of imipenem resistant pseudomonas aeruginousa had been isolated in clinic and their drug sensitivity to antibacterials was tested by KB slip diffusion method and analyzed statistically.RESULTS:Meropenem,amikacin,and ceftazidime were among the antibacterials that kept high antibacterial activity and had resistance rates less than35%included.CONCLUSIONS:Imipenem resistant pseudomonas aeruginosa strain has stronger resistance to commonly used antibacterials and its multidrug resistance is more severe.Rational use of antibacterials can help to control and lessen the drug resistance of bacteria.

Objective To investigate the stapled trans-anal rectal resection (STARR) and Altemeir's resection for rectum prolapse in spinalcord injury (SCI) patients. Methods Anus bowel disease of 260 SCI patients were investigated, 21 cases with rectum prolapse who wereinvalid for nonoperative treatment chose Altemeir's resection or STARR depending on the degree of rectum prolapse. They were recorded ac- cording to International Spinal Cord Injury Bowel Function Based and Extension Set before and 12 months after operation. Results 85 SCIpatients were with rectum prolapse (32.7%), 21 patients complicated with constipation and mixed hemorrhoid, 19 with rectal mucous membraneprolapse (<7 cm), 4 with rectal internal mucous intussusception, 2 were completely rectum prolapse (≥7 cm). Rectum prolapse of Ⅰdegree was found in 13 cases, Ⅱ in 5 cases, and Ⅲ in 3 cases. Patients with Ⅰ or Ⅱ degrees rectum prolapse accepted STARR, those withⅢ degrees accepted Altemeir's resection. No serious complication was found. Self-report of intestinal dysfunction affecting the quality oflife during the 12 months after operation significantly decreased (P<0.01), so as the need of drawing out defecate with hands (P<0.01), theusage of liner, plug, or antidiarrheal (P<0.001). The symptom such as endless defecate feeling, abdominal distension, abdominal pain, abdominaldiscomfort were significantly alleviated (P<0.05). Conclusion STARR and Altemeir's resection are both safe and effective operationfor rectum prolapse in SCI patients.

Objective To study the value of serum tartrate-resistant acid phosphatase 5b (TRACP5b) in bone metastasis in early breast cancer patients with negative axillary lymph nodes.Methods The serum level of TRACP5b was determined by enzyme-linked immumosorbent assay (ELISA) in 26 breast cancer patients and 18 healthy female adults.Results The serum level of TRACP5b was (3.85 ± 0.85) U/L in the group of breast cancer patients and (2.08 ± 0.84) U/L in the control group.The difference had statistical significance (P ＜0.05 ).The sensitivity was 42.31％ and the specificity was 94.44％ for TRACP5 b in predicting bone metastasis of breast cancer with negtive axillary lymph nodes.Conclusions TRACP5b has higher sensitivity and specificity in breast cancer patients than in healthy female adults.TRACP5b is a useful serum marker to predict bone metastasis in breast cancer patients.

The American Clinical Practice Guiding -Neurogenic Bowel Management in Adults with Spinal Cord Injury (SCI) had been prepared based on scientific and professional information known about neurogenic bowel management, its causes, and its treatment, in 1998. It will provide reference to China's neurogenic bowel management after SCI in rehabilitation and treatment.
