OBJECTIVE To evaluate the distribution and drug resistance of pathogens in patients of liver cirrhosis combined with spontaneous bacterial peritonitis(SBP),and provide the credible evidence with the clinic diagnosis and the treatment of SBP.METHODS Totally 113 cases of hospitalized cirrhotic patients with SBP were admitted to our hospital between Mar,2000 and Dec,2005.Ascitic fluids of all cases were cultured.The total 114 strains of pathogens were identified and the drug resistance was analyzed.RESULTS Escherichia coli among the pathogens infected the ascitic fluids rated the top(39.5%),the next were Klebsiella pneumoniae,Enterobacter cloacae and Acinetobacter baumannii.The drug resistance of E.coli to imipenem was the lowest,about 2.2%.CONCLUSIONS The diagnosis of SBP with cirrhosis mainly depended on both of ascites results and clinical symptoms.The clinic should reasonably choose the antibiotics according to the test results of the pathogens sensitivity to drugs.

Objective To investigate the factors that affecting the efficacy of arthroscopic debridement in the treatment of knee osteoar-thritis. Methods The clinical data of patients with knee osteoarthritis treated with arthroscopic debridement in our hospital from January 2009 to December 2013 was retrospectively analyzed,and the treatment effect was evaluated by Lysholm score. The factors that may affect the efficacy were selected to make a single factor analysis,and then made a multiple logistic regression analysis with the factors which were of sta-tistical significance through single factor analysis. Results Single factor analysis showed that age,course of disease,body mass index,psycho-logical factor,preoperative VAS score,preoperative Kellgren-Lawrence grade,preoperative Lysholm score and postoperative rehabilitation exer-cise were the factors that affected the efficacy of knee arthroscopy in the treatment of knee osteoarthritis,and the difference between the two groups was statistically significant. Further multivariate analysis showed that high body mass index,high preoperative VAS pain score,low Ly-sholm score,high psychological expectations and high preoperative Kellgren-Lawrence grading were expected to be the independent risk fac-tors of knee arthroscopy in the treatment of knee osteoarthritis. Strict compliance with the postoperative rehabilitation exercise was the protect factor. Conclusion High body mass index,high preoperative VAS pain score,low preoperative Lysholm score,high preoperative Kellgren-Lawrence grading,and high psychological expectations were expected to reduce the effect of surgery,while strict compliance with the postoper-ative rehabilitation exercise can improve the curative effect.
