OBJECTIVE To analyze infection state and drug resistance feature of Staphylococcus spp with a view of offering references for controlling and treating infection led by it.METHODS Totally 652 strains of Staphylococcus isolated from patients with infection were identified and their drug resistance was analyzed.RESULTS From them 204 strains were Staphylococcus aureus and 448 strains were coagulase negative Staphylococcus detected and the isolating rate of MRSA and MRCNS were respectively accounted for 55.4% and 84.6%.The most common coagulase negative Staphylococcus strains were S.haemolyticus and S.epidermidis.The drug-resistant rates of MRS were higher transparently than MSS.CONCLUSIONS Staphylococcus are one of the main pathogens leading to nosocomial infections.As a result, it is very important to use antibiotics properly for infection control and nosocomial infection management.

A microscopic fluorescence spectrometric analysis ( MFSA) system was set in the laboratory. A novel method for in situ determination of Anthracene ( Ant) adsorbed onto root surface micro-zone of two kinks of mangrove plant, named Kandelia obovata ( K. obovata) and Avicennia marina ( A. marina) by MFSA was established. Fluorescence spectra of Ant adsorbed on root surface micro-zone were obtained by synchronous scanning mode. The signal to noise (S/N) of Ant (5. 3 pg/μm2) adsorbed on K. obovata and A. marina root surface micro-zone increased up to 5. 5 and 6. 8 while wavelength offset (△λ) both were at 60 nm, respectively. The linear dynamic ranges of established method were 5. 3-63. 2 pg/μm2 for K. obovata and 10. 5-52. 6 pg/μm2 for A. marina, with the detection limits of 1. 1 pg/μm2 and 5. 5 pg/μm2 , respectively. The relative standard deviations were both less than 12 . 5% ( n=9 ) , and the recoveries were 98 . 1% -117. 0% and 81. 2%-110. 9%, respectively. The result showed that the MFSA system had ability to obtain quantitative information of fluorescence spectra and fluorescence image of Ant adsorbed onto plant roots surface micro-zone.

Objective To discuss the feasibility of percutaneous nephrolithotomy (PCNL) for treating upper urinary calculi under local anesthesia.Methods One thousand three hundred and sixty-three patients who suffered with upper urinary calculi were treated with PCNL, the puncture and tracts were created using local anesthesia and guided through ultrasound.Of the 1363 patients, 475 patients had complicated renal caluli, 520 patients had kidney pelvic calculi and 368 had upper uretere calculi.Results All of the patients successfully received PCNL under the local anesthesia.Of the 1363 patients five tracts were used in two patients, four tracts were used in four patients, three tracts were used in nine patients, double tracts were used in 25 patents and one tract was used in the remaining patients.The stone-free rate was 96.0% in the kidney pelvic calculi patients, 100.0% in the upper uretere calculi patients, and 90.1% in the complicated renal caluli patients.90.0% patients were find well throught the operation, 10.0% patients find a little pain and solved by another more 5 - 10 ml lidocaine local injection or 50 - 75 mg pethidine hydrochloride intramuscular injection.No case stop operation because of pain or position changed.All without any severe complications such as damaged of liver, spleen, thorax and intestine.Conclusion The PCNL handled under local anesthesia was simple safe and effective, deserved clinical popularizing use.

Objective To explore the mediating effect of perceived social support on the relationship between perfectionism and depression. Methods 454 college students completed Almost Perfectionism Scale Revised Chinese Revised, Perceived Social Support Scale and Beck Depression Inventory. SPSS 12.0 was used for Spearman Correlation Analysis and Lisrel 8. 70 was used for Structural Equation Model Analysis. Results The model(M1) fit indexes of perceived social supports partial mediating effect on the relationship between discrepancy and depression were χ2/df = 2.15, RMSEA = 0.049, SRMR = 0.068, NNFI = 0.97, CFI = 0.98, IFI = 0.98, PNF1 =0.74, ECVI =0. 35. The model( M3) fit indexes of the relationship among high standard, discrepancy, perceived social support and depression were χ2/df = 1.77, RMSEA = 0.040, SRMR = 0.059, NNFI = 0.98, CFI = 0.98, IFI = 0.98, PNFI = 0.76, ECVI = 0.48. The two models were proved well. Conclusions Perceived social support partially mediates the relationship between the negative component of perfectionism and depression; The positive component of perfectionism moderates the relationship between the negative component of perfectionism and depression; Considering the effect of the positive component of perfectionism, perceived social support still partially mediates the relationship between the negative component of perfectionism and depression; To change the perceived social support of level may help perfectionistic individuals to decrease their depressive level.

Objective To evaluate the clinical applications of rigid dilatation using double catheter method for ureteric stenosis.Methods The clinical data of 51 ureteric stenosis patients who had underwent rigid dilatation using double catheters method were retrospectively analyzed. Results Among the 51 patients,the ureteroscopy successfully went through the stricture in 46 cases(90.2%),and all patients had no ureteral perforation or laceration.Among the 5 patients in whom ureteroscopy did not go successfully through the stricture,2 cases were placed double J tube,2 cases underwent percutaneous nephrolithotomy,and 1 case underwent two stage ureteral stricture resection and religation.All patients were examined by ultrasound examination 3 months after the treatment,and the degree of hydronephrosis was partial remission. Conclusions The double catheters method is a safe and effective way for rigid dilatation for ureteric stenosis,and it is worth popularizing.

OBJECTIVE[corrected] To evaluate the method and technique of single-port laparoscopic radical nephrectomy.

METHODSForm January 2009 to September 2011, 22 patients with renal carcinoma were treated with single-port laparoscopic radical nephrectomy. An incision about 5 cm in length was made through the umbilicus or in the postaxillary line under the 12th rib to establish the peritoneal or retroperitoneal working space. A single-port cannulation was deployed and the operation was carried out using standard and crooked laparoscopic equipment.

RESULTSThe operations were completed successfully in all the 22 cases without conversion to open surgery, but additional trocar was needed in 5 cases. The mean operative time of radical nephrectomy was 150 min (90-240 min). The mean postoperative hospital stay was 7.6 days (3-15 days). The operation left a roughly 5-cm-long scar in all the cases.

CONCLUSIONSingle-port laparoscopic radical nephrectomy is safe and feasible with good cosmetic effect and shows much potential in radical resection of renal carcinoma.
