BACKGROUND:Recently, there are many documents al over the world reporting hypotoxicity infection after fracture internal fixation surgery, but reports are different on whether it is necessary for chronic hypotoxicity infection internal fixation removal post surgery. There are no fixed judgment criteria of curative effects, which leads to inexact conclusion of treatment method. ＜br> OBJECTIVE:To observe the curative effects of taking rifampicin and ciprofloxacin with transfer of skin flap in the treatment of chronic hypotoxicity infection with sinus formation after fracture surgery on tibial plateau and ankle. METHODS:A total of 56 cases of chronic hypotoxicity infection after fracture surgery of tibial plateau and ankle were col ected from September 2005 to December 2012. 30 cases in the therapy group were treated with ＜br> levofloxacin and rifampicin with transfer of skin flap. 26 cases in the control group were treated with conventional intravenous antibiotics with local debridement to remove internal fixation. In both groups, the course of disease was 3 to 6 months. The erythrocyte sedimentation rate, kidney function and radiographic indices were reviewed every 1 to 3 months, and curative effects were evaluated. ＜br> RESULTS AND CONCLUSION:During the fol ow-up visit of 6-24 months, no recurrence happened to the cured and improved patients. In the therapy group, 24 cases were cured, 4 cases were improved, and 2 cases were invalid, with a total effective rate of 93%. In the control group, 11 cases were cured, 6 cases were improved and 9 cases were invalid with the total effective rate of 65%.χ2 test showed that therapeutic effects were significantly better in the therapy group than in the control group (P＜0.05). These data indicated that rifampicin and ciprofloxacin with transfer of skin flap for chronic hypotoxicity infection with sinus formation after fracture surgery of tibial plateau and ankle showed good curative effects.

Objective To report a multi-center series of 600 consecutive cases of completely video-assisted thoracoscopic lobectomy with 3-year follow-up results. Methods Data from 600 consecutive patients who underwent attempts for thoracoscopic lobectomy between September 2006 and August 2010 in Peking University People's Hospital, Jiangsu Cancer Hospital and Beijing Haidian Hospital were collected. Of these, 315 males (52.5%) and 285 females (47.5%), the average age was ( 59.1 ± 12.6 ) years( 15 - 86 years). Perioperative variables were assessed using standard descriptive statistics and 3-year survival was estimated by Kaplan-Meier analyses. Results One hundred and nineteen cases were diagnosed as benign disease and 481 cases were malignancy. 68.9% (82/119) of the benign cases were chronic infectious disease and the majority of the malignancy was non-small cell lung cancer, especially adenocarcinomas which comprised 65.9% (317/481) of all malignancies.Fifty-four cases required conversion to thoracotomy with a conversion rate of 9%. Of the VATS accomplished group, the median operation time was 180 min(30 -40 min), median blood loss 200 ml( 10 - 1500 ml) . Benign surgery took significantly less time, had shorter drainage time and hospitalization time, and lower morbidity than that for malignancies ( P = 0.001, P ＜0.01, P = 0.004, P = 0.020, respectively). Non-small cell lung cancer patients had a 3 -year survival of 85.4%, and pathologic stage Ⅰ patients 91.2%. Conclusion This largest case series and the first report 3-year survival in China confirms that completely thoracoscopic lobectomy surgery we performed have reached short- and middle-term standards compared with that of the western country.

ObjectiveTo determine the epidemiological characteristics and transmission factors of a varicella outbreak in a school in Nanxun District of Huzhou City， and assess the effect of prevention and control measures， which may provide scientific evidence for improvement in the response to varicella outbreak. MethodsData were collected by field epidemiological survey and analyzed by descriptive epidemiology. Statistical analysis was performed by SPSS 22.0 software. ResultsA total of 80 varicella cases were identified in this outbreak， which lasted 68 days. There were four peaks of incidence， involving 21 classes. The total incidence rate was determined to be 4.14%. Before the public health intervention， some cases were not isolated in time， which led to the initial spread in the class. After the mid-term examination， the outbreak further spread to multiple classes. Breakthrough varicella cases accounted for 48.75% of all the cases in the outbreak， among which 94.87% had been vaccinated for more than five years. However， there was no significant difference in the incidence of fever and rash between the breakthrough cases and non-breakthrough cases（P>0.05）. ConclusionTimely report， prompt response， and strict implementation of prevention and control measures remain crucial for effective containment of varicella outbreak.
