Fourteen patients of OFIW were treated by the plaster cast and wound dressing (PCWD), and 30 patients of OFIW were treated by STIT. The results indicated that after one week of treatment, the white blood cell count in the STIT group, compared to 17. 6±l. 0×109/L from before treatment, returned to 8. 8±0. 8×109/L,and in contrast, the cell count of the PCWD group was about 13. 0±1. 4×109/L. All of wound exudate culture in the STIT group was negative, and those of 7 cases (7/14) in PCWD group were positive (P<0. 0l). The symptoms and signs such as pain, fever and septic exudate on the wound in the STIT group were much milder than those in the PCWD group. There were 5 cases (35. 7%) of toxicemia and septicemia, 2 cases (14. 3%) of osteomyelitis, 2 cases (14. 3 %) of amputation, 1 case (7. 1%) of delayed union and 3 cases (21. 4 %) of malunion in the PCWD group, and no complications in the STIT group.展开更多

Dilution test was used to measure antibacterial activity of N. oculata extracts. Antioxidant activity of extracts was expressed by levels of MDA （Malondialdehyde） and SOD （superoxide dismutase） in the brain and kidneys of fish. Antiviral capability of N. oculata was determined by the expression of cellular immune cells Major Histocompatibility Complex （MHC） Class I for proliferation and inhibition of VNN in blood cells with immunocytochemistry. The results showed that N. oculata extract was able to suppress the growth of V. alginolyticus at a concentration of 40%. Increasing levels of SOD and reducing level of MDA indicated that N. oculata extracts may serve as an antibacterial and antioxidant. Providing cellular response of MHC class I cell expressed on C. altive/is blood cells, N. oculata demonstrated its antiviral activity.展开更多

Methods Between April 1999 and June 2006, 60 patients presented to our department with infectious renal stones. Twenty-nine patients were treated by extracorporeal shock-wave lithortripsy(ESWL) only, 31 patients were given a combination therapy. Thirty-four males and 26 females were evaluated by routine urine tests including urine culture and sensitivity before ESWL treatments. The total number of shock waves varied from 1 600 to 2 800 and the energy levels ranged from 1 to 6 unit. Results The fragmentation after ESWL was 61.6%; 18.3% after 2 ESWL sessions, 8.3% after 3 ESWL sessions, 5.0% after 4 ESWL sessions, 3.3% after 7 ESWL sessions and 1.66% after 9 ESWL sessions. Only one (1.66%) patient failed and changed to open surgery. Conclusion ESWL is an effective and reliable treatment for patients with infectious renal stones. However, better effects and shorter treatment time is obtained by the combination therapy of ESWL with other therapy options.展开更多

Group A consisted of 48 patients with 1 to 4 renal calculi, which were or less than 2 crn in diameter. Group B was composed of 24 patients with renal calculus larger than 2 cm in diameter or one to multiple renal calculi. Group C wes composed of 22 patients with 1 to 3 renal calculi accompanied by 1 to 2 ureteric calculi. Group D consisted of 51 patients with 1 to 3 ureteric calculi that were 0.5 to 1.2 cm in diameter, respectively. Group E included 19 patients with complicated renal calculus, such es casting and staghom renal calculus. Urine and blood samples of these patients were obtained before and after ESWL, respectively. Their urine samples were proven sterile prior to treatment. All samples were cultured for bacteria and investigated for endotoxin concentration by the limulus lysate test.Results No significant difference in serum endotoxin wes noted before and after ESWL. Blood bacterial cultures were all negative in all patients after ESWL, similar to those before ESWL. Significant increases in urine endotoxin after ESWL compared with that before ESWL in patients of Groups B, C and E were observed, respectively (P ＜ 0.05). There was no significant difference in urine endotoxin after ESWL compared with that before ESWL in patients of Groups A and D. The positive incidences of urine bacterial culture were significantly increased (P ＜ 0.05) in Groups B and C and very significantly increased ( P ＜ 0.01 ) in Group E compared with those in Groups A and D.Conclusions Urinary infection risk following ESWL was lower in patients with one to several renal calculi,which were less than 2 cm in diameter and did not interfere obviously with the urine flow or in patients with 1 to 3 ureteric calculi that were 0. 5 to 1.2 cm in diameter. The risk was higher in those with complicated calculi, such as casting, staghom renal calculus, renal calculus larger than 2 cm in diameter or renal calculi accompanied by ureteric calculi. For patients with higher infection risk after ESWL, prophylactic antibiotics are necessary even if bacteriuria is not present before ESWL. Endotoxin determination in urine is a reliable,sensitive and simple method for the diagnosis of bacterial infection in patients undergoing ESWL.展开更多
