Objective To investigate the relationship between antibiotic administration and the changes in constituent ratios of preponderant pathogens in infection of burn wounds in our burn unit. Methods The consumption of different kinds of antibiotics [expressed as the number of defined daily doses (DDD)/100 patient-day], as well as the constituent ratio of Staphylococcus aureus and Pseudomonas aeruginosa, and percentage of methicillin-resistant S. aureus (MRSA) among all positive cultures of S. aureus were calculated from 1995 to 2004, and their correlation was analyzed. Results Within this period, it was found that the consumption of first and second-generation cephalosporins and aminoglycosides, including cefazolin and amikacin, was decreased remarkably, while the consumption of antibiotics combined with lactamase inhibitor, third-generation cephalosporins, quinolones, including ceftazidime, levofloxacin and fosfomycin, was increased significantly. At the same time, the constituent ratio of P. aeruginosa declined to certain extent, while the constituent ratio of S. aureus gradually rase, but no increase was found in percentage of MRSA in S. aureus. The constituent ratios of S. aureus and P. aeruginosa were correlated to consumption of more than ten kinds of antibiotics or antimicrobial agents. Conclusions The results suggested that more cefazolin or amikacin and less antibiotics with lactamase inhibitor or third generation cephalosporins were used in the treatment of burn infection might help decrease the infection caused by S. aureus, and that when more carbopenem or cefoperazone/sulbactam were used there might be a tendency of declination of P. aeruginosa infection.

Aim To explore the function of immune modulation of anti-HBV iRNA in patients with chronic hepatitis B(CHB) Methods Peripheral blood lymphocyte iRNA was prepared from anti-HBs positive human body with HBV complete clearance after HBV infection(h-iRNA). The effect of h-iRNA on HBV specific lymphocyte proliferative response of peripheral lymphocyte from patients with CHB was observed by using MTT method and was compared with that by HBV specific iRNA from animal immunized only by HBsAg(a-iRNA).Results Both h-iRNA and a-iRNA increased the level of peripheral lymphocyte proliferative response to HBsAg in patients with CHB to some degree. In group of HBcAg, only h-iRNA showed its enhancement of HBcAg specific lymphocyte proliferative response.Conclusions h-iRNA can increase HBV specific lymphocyte proliferative response in patients with CHB and the function of increasing HBcAg specific lymphocyte proliterative response contributes to HBV clearance .

Background Primary open angle glaucoma (POAG) is a major blindness-causing disease,characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork lining the aqueous outflow pathway modulates the aqueous outflow facility. To study the biological characteristics of the trabecular meshwork cells has important significance. Objective This study was to culture the trabecular cells from primary open-angle glaucomatous eye (POAG) and study the biologic characteristics of passaged cells. Methods The deep scleral tissue with trabecular meshwork was obtained during the trabeculectomy from 8 eyes with POAG. The trabecular cells were primarily cultured and passaged in vitro. The generation 3 cells were identified by immunochemistry with the laminin (LM), fibronectin (FN) and neuron specific endolase (NSE)monoclonal antibodies. The ultrastructure was examined to observe the biological characteristics of the cells under the transmission electronic microscope. The experimental results were compared among POAG group, normal control group and blank control group. Results The primarily cultured POAG trabecular cells migrated from the edge of tissue mass about 10 days. The cells of generation 3 presented the logarithmic phase in the first 4 days and fused in the 7th day. FN,LM and NSE were positively expressed in the generated cells in POAG group and normal control group rather than blank control group. The MOD values of the generation 3 cells for FN in POAG group and normal control group were 0. 35 ± 0.06 and 0. 26 ± 0. 01, and those for LM were 0. 34 ± 0. 03 and 0. 25 ± 0. 02 respectively, showing statistically significant difference between these two groups ( FN: t = 14. 446, P＜0.001; LM: t = 9. 346, P＜0. 001 ). The microvilli, cytolysosome and phagocytic vesicle were obviously decreased in the trabcular cells of POAG group compared with normal control group under the transmission electron microscope. Conclusion The trabecular meshwork cells from POAG can be successfully cultured and passaged in vitro. It provides a cytology basis for further glaucoma research.

Objective To explore the best way to diagnose and cure the nephrosis with ureteropelvic junction obstruction(UPJO) in children.Methods The diagnosis of 26 cases of nephrosis with UPJO were confirmed by ultrasonogram and IVU examinations.All patients underwent AndersonHynes procedures.These results were analyzed and summarized.Results All the diagnosis were proved to be correct by operation and pathology examinations,the operations were carried out successfully.Twenty-four cases were followed up for 6 months to 2 years.After the operation,the hematuria,urinary frequency,abdominal mass and distention disappeared,the urine analysis was normal,all cases cured clinically.Ultrasonogram examinations showed the thickness of parenchyma increased and the large kidneys lessened.Significantly improved renal fuoction on IVU examinations was observed in the 24 cases compared with that before the operations.The ureters of 20 cases displayed well.Conclusions The combination of ultrasonogram and IVU is very effective method to diagnose UPJO in children.Anderson-Hynes technique is the best procedure to cure the UPJO.

Objective To evaluate the preoperative diagnosis and treatment of primary non-specific ureteritis,and to better understand this disease.Methods Three cases of primary non-specific ureteritis (1 man and 2 women)were reported.Their age was 28,38,68 years,respectively.One ease was found to have hydronephrosis on B-ultrasound at physical examination with no symptoms,and 2 had abdominal pain. The lesions were detected in lower part of the ureter in 2 cases,and in middle in I.The patients were diag- nosed preoperatively with combined use of MRU and ureteroscopy.Partial resection of the diseased part of the ureter was performed in all the cases.Results Pathological findings confirmed the diagnosis of non-spe- cific ureteritis.Microscopy showed necrotic tissue and inflammatory cell infiltration of ureteral mucosa,dilated and congested blood vessels,hypertrophic muscular layer,and proliferation of fibrous tissue.During the fol- low-up of 2 years,the patients had no symptoms and were free from hydronephrosis.Conclusions The eti- ology of primary non-specific ureteritis is unclear,and no typical symptoms can be found clinically.Combined use of MRU and ureteroscopy is helpful for definite diagnosis of the disease.Partial resection of the diseased part of the ureter has good results.
