Objective To observe the effect of traditional Chinese medicine internal and external treatment on chronic osteomyelitis.Method Chronic osteomyelitis experimental animal models were set up with debridement, then it was random divided into two groups ( antibiotics group for the control group, antibiotics and traditional Chinese medicine group for the observation group).After treatment for 10 days, new capillaries in the tissues surrounding sinus crossings were detected by pathological observation and VEGF expression was determined by ELISA.Result VEGF expression and vascular points of tissues surrounding sinus crossings of antibiotics with traditional Chinese medicine group were obviously higher than that of antibiotics group[ (47.48 ±3.22) μg/ml vs (28.26 ±2.61)μg/ml, P <0.01;8.03 ±1.73 vs5.17 ±2.89, P<0.05 ].Conclusion Traditional Chinese medicine internal and external treatment can improve VEGF expression and increase capillary number inside tissues surrounding sinus.crossings , thus it can promote the healing of chronic osteomyelitis.

Objective To investigate the technique of radio-stereotactic mammography aspiration biopsy(SCNB) and the clinical usage.Methods The stereotactic mammography aspiration biopsy was performed on 38 breast focuses,the results were compared with pathology.The technique and operation skills of SCNB were studied.Results In this 38 breast focuses,the accuracy of diagnostic aspiration,misplay and false negativity were 84.2%,7.89%and 7.89% respectively.No false positive was found.Conclusion In this technique,the distance between the needle tip and focus central was calculated by computer.This is a effective,easy operate and safe tool for the localization and very valuable in the diagnosis of a early cancer.

Objective This retrospective study is performed to analyze the epidemiological and clinical features of patients with infective endocarditis (IE) hospitalized in Fuwai Cardiovascular Hospital during the latest 7 years.Methods This retrospective study included a cohort of 368 infective endocarditis patients hospitalized in Fuwai Hospital form August 2005 to August 2012.Predisposing cardiac diseases,causative organisms,clinical features and outcomes were analyzed.Risk factors related to outcome including NYHA classes,causative organisms and complications,were evaluated.Results Among the IE patients,6.8% (25/368) patients had rheumatic heart diseases 31.8% (117/368) had congenital heart diseases,22.8% (84/368) were post-PCI or operative endocarditis and IE developed in 14.1% (52/368) patients without previous cardiac diseases.Blood culture positive rate was 46.2% (170/368).Streptococci viridians [27.6% (47/170)]were the most common causative organisms,followed by coagulase-negative staphylococci [15.9% (27/170)].Fever and cardiac murmur were the most common clinical presentations.Congestive heart failure was the most common complication [87.8% (323/368)].Systemic and pulmonary embolism occurred in 16.0% patients,80.9% IE was detected by echocardiography.In-hospital mortality rate was 6.7%,mostly due to refractory congestive heart failure and sepsis.Subgroup analysis showed that incidence of post-PCI or operative endocarditis was significantly higher in IE patients hospitalized after 2009 compared to IE patients hospitalized before 2009 (27.5% vs.19.2%,P < 0.05).Higher incidence of staphylococcal infection was evidenced in mechanical valves than in native valves(44.4% vs.19.8%,P < 0.05).Conclusion During the past decade,there is a significant change on epidemiology and clinical features of IE in China.Incidence of post-surgical and interventional IE increased significantly.Staphylococcal and Gram negative bacilli infection are major pathorganisms of endocarditis of mechanical valves.Due to the lower positive rate of blood culture,echocardiography serves as the most important diagnostic tool for infective endocarditis.
