??Risk factors and prevention of surgical site infection LIU Hong-bin. Department of General Surgery, General Hospital of Lanzhou Command of PLA??Lanzhou 730050??China
Abstract Surgical site infection (SSI) is the most common complication after surgical operation. It can cause the increasement of hospitalization expense??extension of hospitalization time and the incidence and mortality of postoperative complications. The increasing of the difficulty and complexity of surgery??transfer technique and prosthesis implantation, immunosuppressant and hormones used widely and misuse of antibiotics may increase the incidence of SSI. With the rapid development of minimally invasive surgery and enhanced recovery after surgery (ERAS), prevent SSI are facing new challenges. So SSI should cause the attention of the society and hospitals. With the improvement of medical treatment level??the standardized treatment measures of SSI should be formulated and implemented. SSI should be prevented from forecast??diagnosis??perioperative managemant. SSI shoule be managed comprehensively in every level of patients, medical staff and environment.     

儿童先天代谢异常伴发的肥厚型心肌病

儿童先天代谢异常是导致肥厚型心肌病（HCM）的重要病因, 掌握每种疾病的特征性表现有助于正确的诊断及鉴别诊断。多数先天代谢异常伴发HCM属于常染色体隐性遗传,少数为常染色体显性遗传X连锁遗传方式,部分线粒体病呈母系遗传。常规心电图、超声心动图等心脏检查即可以为部分疾病的基础病因找到诊断线索。随着酶替代疗法等新的治疗方法的不断进步,加强心脏评估,恰当地针对原发病治疗,多学科协同合作将为越来越多的患者生存提供可能。

Abstract Objective To identify the perioperative complication incidence and its risk factors in patients underwent ileal/ileocecal resection for chronic radiation enteritis (CRE) with small bowel obstruction. Methods Univariate and multivariate analysis of a retrospectively gathered database between June 2001 and December 2011 in Department of General Surgery, Nanjing General Hospital of Nanjing Military Command PLA were performed on a cohort of patients (n=158) underwent ileal/ileocecal resection for CRE obstruction at a single institution. Altogether, we analyzed 33 potential risk factors to identify significant influence on the postoperative outcome. Results Overall and major morbidity rates were 57.0% (90 patients) and 28.5% (45 patients), respectively. The mortality rate was 1.9% (3 patients). Univariate analysis determined that ASA score of not less than 3, anemia, low platelet level, long operation time, intraoperative transfusion, presence of radiation uropathy and proctitis and experience of surgeons were important risk factors for Grade ??-?? morbidity. Multivariate analysis found ASA score of not less than 3, anemia, intraoperative transfusion, low platelet level, radiation uropathy and surgeon’s experience as independent risk factors for Grade ??-?? morbidity. Conclusion The current study provides the first evidence of predictive risk factors for postoperative morbidity of ileal/ileocecal resection for CRE.     

肝硬化慢性肝衰竭临床治疗实践

临床综合治疗是肝硬化慢性肝衰竭救治的基本方法。强调控制感染、营养支持、及早输注新鲜血浆或全血、白蛋白的重要性，保持水、电解质平衡，维护机体内环境稳定及控制肠源性内毒素血症是临床救治成功的关键，同时积极预防及治疗并发症，肝移植是目前临床上公认的终末期肝病最有效的治疗手段。

??Aggressive periodontitis??AgP??is a type of periodontitis with early onset and rapid progression??which mostly affects young adults. The most common problems found in AgP patients include severe periodontal destruction and pathologic tooth migration??PTM????which impair function and aesthetics of the stomatognathic system. Effective orthodontic treatment not only provides an acceptable functional and aesthetic occlusion??and corrects traumatic occlusion??but also stimulates rebuilding of the original periodontal architecture and achieves long-term stability. Hence??it is of utmost importance for an orthodontist to have knowledge and ability to manage the case of aggressive periodontitis with multidisciplinary approach??create harmonious cooperation with the periodontist??initiate the orthodontic treatment after the achievement of proper plaque control??and stick to the strategy of proper design of active treatment??placement with light force??strict control of oral hygiene??regular periodontal maintenance and careful monitoring of the whole course.

??Abstract??Objective To make doctor perform operation accurately on patients with dentomaxillofacial deformity by preoperative simulation based on digital data which was collected by digital software. Methods Fifteen patients had previously undergone 3-dimensional computed tomography and the data from CT scan were input into digital software. We used the software to simulate operations preoperatively including fixing point??osteotomies and movements of jaw bones. The collected information from software was applied to actual operations. Results All the operations had been completed successfully without serious complication. The patients were satisfied with the effect of operation 6 months after operation??with a satisfaction rate of 93.3%. Conclusion The digital simulation technique is a precise method which provides practical and effective basis for establishing the preoperative planning of individual optimal surgical procedure for patients with dentomaxillofacial deformities in orthognathic surgery.
