Epidemiological analysis of measles in China between 2005 and 2013 / 军事医学

Objective To analyze the epidemiologic characteristics and epidemic intensity of measles in China between 2005 and 2013 , and to provide evidence for reasonable allocation of health resources and measles elimination in China . Methods Descriptive epidemiological methods were applied to measles surveillance data and demographic information during this study.Results A total of 597 594 cases, including 366 deaths, were reported from all over China , among whom 355 409 were males (59.47%) and 242 185 were females (40.53%).The average annual incidence was 5.07/100 000 and the average annual mortality was 0.0031/100 000.The majority of cases were children under 10 years old, accouning for 64.64%.Conclusion The incidence of measles in China is decreasing .Measles mainly occurrs in spring and there is significant difference between age and gender groups , and obvious regional differences are also found .

Comparison of different methods to revascularize the isolated left anterior descending artery disease / 中华胸心血管外科杂志

Objective Off-pump coronary artery bypass (OPCAB),minimally invasive direct coronary artery bypass (MIDCAB) and robotic-assisted coronary artery bypass (RA-CAB) are all used to treat isolated left anterior descending artery (LAD) disease.The aim of this study is to compare the early outcomes after these three procedures.Methods From February 2009 to May 2012,102 consecutive patients underwent revascularization of LAD.31 patients were treated by OPCAB,45 by MIDCAB and 26 by RA-CAB.Patients received sternotomy in the OPCAB procedures.The MIDCAB procedures were performed through a 10-cm anterolateral muscle-sparing minithoracotomy.In the RA-CAB procedures,left internal mammary arteries (LIMA) were harvested with the aid of da Vinci surgical system and sewing of the anastomoses was performed under direct vision by a 3-cm anterolateral minithoracotomy.Results No significant difference was observed in graft flow,pulse index,renal failure,reoperation for hleeding,new onset of arterial fibrillation and deep wound infection between these three groups.There was also no significant difference in peri-operative mortality,major adverse cerebro-cardiovascular events (MACCE) between these three groups.Compared with OPCAB,MIDCAB and RA-CAB significantly reduced the need of blood transfusion (4.4％ vs.32.3％,P＜ 0.05; 7.7％ vs.32.3％,P＜0.05).The patients receiving RA-CAB had shorter length of postoperative stay than whom receiving OPCAB[(8.8 ± 3.2) days vs.(12.4 ± 7.7) days,P ＜ 0.05)].There is no significant difference between the outcomes of MIDCAB and RA-CAB.Conclusion These findings indicated that MIDCAB and RA-CABwere feasible,effective and safe options for revascularization of isolated LAD disease.MIDCAB and RA-CAB showed the advantage of less invasive and faster recovery,compared with OPCAB.Therefore,MIDCAB and RA-CAB should be the routine treatment for patients with isolated LAD disease.In some advanced centers,RA-CAB will be the preferred method.The mid-and long-term outcomes of these three methods should be further investigated.
