OBJECTIVETo investigate the application of microsurgical technique in the replantation of amputated ear.

METHODS7 cases of amputated ears were analyzed from June 2009 to April 2015 in our department. We used microsurgical technique to anastomose about five vessels and nerves. The blood supply of auricle was restored within three to six hours. All subjects underwent treatments including anti-freezing, anti-spasm and anti-infection treatment after the emergency surgery.

RESULTS7 amputated ears were all survived after replantation. The patients were followed up for one month to six months ( average for 28 months). The appearances of survived ears body were fully recovered without any significant atrophy or pigmentation. The sensory function of ears recovered to normal after 1 year.

CONCLUSIONSThe application of microsurgical technique in the replantation of amputated ear can expect the high success rate of ear replantation. However, skilled and high-quality anastomosis technique of small vascular are required.

Objective To evaluate the anti-schistosomiasis effect of World Bank loan for schistosomiasis control project 1992-2001 in Jingzhou City, Hubei Province, and observe the endemic situation after two years of the end of the project.Methods By a retrospective longitudinal survey, information from annual reports was collected, which included disease screening, treatment and extended chemotherapy for human population and livestock, the distribution of Oncomelania hupensis and health education information from eight counties in Jinzhou prefecture from 1992 to 2003.Statistical u test was used for phased retrospective dynamic analysis.Results In the year 2001, schistosomiasis patients(77 009 cases)were 45.2% less than that of 1992(140 438 cases), The number of acute and advanced cases(63 and 1 032 cases, respectively)was 74.2% and 43.9% less than those of 1992(244 and 1 841 cases, respectively).The average infection rate among residents was also reduced from 7.8% of 1992 to 4.7%(u=28.864, P
