Patients undergoing major oncological surgery for head and neck cancer (SHNC) have a particularly high risk of nosocomial infections. We aimed to identify risk factors for ventilator-associated pneumonia (VAP) in patients undergoing SHNC. The study included 465 patients who underwent SHNC between June 2011 and June 2014. The rate of VAP, risk factors for VAP, and biological aspects of VAP were retrospectively evaluated. The incidence of VAP was 19.6% (n=95) in patients who required more than 48 h of mechanical ventilation. Staphylococcus (37.7%), Enterobacteriaceae (32.1%), Pseudomonas(20.8%), and Haemophilus (16.9%) were the major bacterial species that caused VAP. The independent risk factors for VAP were advanced age, current smoking status, chronic obstructive pulmonary disease, and a higher simplified acute physiology score system II upon admission. Tracheostomy was an independent protective factor for VAP. The median length of stay in the ICU for patients who did or did not develop VAP was 8.0 and 6.5 days, respectively (P=0.006). Mortality among patients who did or did not develop VAP was 16.8% and 8.4%, respectively (P<0.001). The potential economic impact of VAP was high because of the significantly extended duration of ventilation. A predictive regression model was developed with a sensitivity of 95.3% and a specificity of 69.4%. VAP is common in patients who are undergoing SHNC and who require more than 48 h of mechanical ventilation. Therefore, innovative preventive measures should be developed and applied in this high-risk population.

Head and neck cancer (HNC) consists of a group of malignancies affecting closely related anatomical regions of the upper aerodigestive tract (UADT), including the oral cavity, salivary glands, upper and lower jaw bones and facial skin; the nasal cavity, paranasal sinuses, pharynx, larynx and thyroid gland (although the latter is often excluded and considered as part of endocrine neoplasms). Of these, 90% of HNCs are histologically squamous cell carcinomas originating from the mucosal lining. These malignancies are strongly associated with certain environmental and life-style risk factors, principally tobacco in both smoked and smokeless forms, excessive alcohol consumption, diets poor in antioxidants and essential micronutrients, UV light, chemicals used in certain workplaces, and viruses, principally certain strains of human papillomavirus (HPV) and Epstein-Barr virus (EBV). These cancers are frequently aggressive in their biological behaviour with local invasion and metastasis to lymph nodes in the neck. Since most patients are already at late stages of disease at the time of diagnosis, the desirable practice of early diagnosis (first sign of the malignant lesion at an initial stage ) and early treatment, a critical priority to save lives and retain quality of life, is difficult to implement. Thus, primary prevention has been set as a key goal. This article aims to reinforce the basic knowledge of aetiology, key risk factors related to the development of head and neck cancer, basic features of clinical appearance of this group of cancers, and strategies for prevention and early detection. We also suggest basic research strategies on the basis of current knowledge, which should ultimately lead to the improvement of clinical management.

软骨缺损难以自行修复,组织工程是实现软骨再生的理想途径。目前,组织工程软骨主要有两类用途:一是用于骨科或关节外科,修复关节表面或半月板部位的软骨缺损,实现关节运动功能的重建;二是用于整形或头颈外科,修复耳廓、气管、睑板、鼻、喉等具有特殊形态及功能的软骨缺损。不同应用目标的组织工程软骨,其构建方法和所面临的挑战,以及临床转化进程均会有很大差别。本文旨在针对上述两大应用目标,结合我们团队在研究过程中所建立的观点及积累的经验,对组织工程软骨目前的主要研究进展和所面临的挑战,以及未来的发展方向做一简要总结。

Video-assisted thoracoscopic surgery (VATS) provides a new approach for treating early-stage lung cancer. Lobectomy by VATS has many advantages over conventional thoracotomy, such as shorter recovery time, less postoperative pain, and faster resumption of a normal lifestyle. However, there is still much debate on the role of VATS in lobectomy for the treatment of lung cancer. Concerns regarding safety, the extent of mediastinal lymph node dissection, and long-term survival have made some surgeons apprehensive of its validity for lung cancer. In this paper, we review the development of thoracoscopy, the present status of VATS for early stage of non-small cell lung cancer (NSCLC), and comparison between VATS and open thoracotomy in the management of NSCLC.

A total of 251 patients with epithelial ovarian cancer (EOC) treated between 2002 and 2008 was retrospectively analyzed to investigate the long-term outcomes and prognostic factors of these patients, particularly those who underwent primary debulking surgery followed by platinum-based chemotherapy. Clinico-pathological parameters, including progression-free survival (PFS) and overall survival (OS), were also analyzed. The median follow-up period from the end of initial treatment to June 2010 was 58 months. The three-year PFS rate was 61.7% for International Federation of Gynecology and Obstetrics (FIGO) I–II, 19.9% for FIGO III–IV, and 33.9% for all stages. By comparison, the five-year PFS rate was 44.6% for FIGO I–II, 17.7% for FIGO III–IV, and 28.3% for all stages. The three-year OS rate was 67.9% for FIGO I–II, 41.7% for FIGO III–IV, and 50.2% for all stages. The five-year OS rate was 52.7% for FIGO I–II, 30.8% for FIGO III–IV, and 39.2% for all stages. Univariate analysis revealed that advanced FIGO stage, serum CA125, and suboptimal debulking were significant factors affecting PFS and OS. In multivariate analysis, PFS was significantly influenced by FIGO stage and suboptimal debulking. However, OS was significantly influenced by advanced FIGO stage only. Our study confirms the efficacy of surgery followed by platinum-based chemotherapy for EOC. FIGO stage is considered as one of the most reliable predictors of the prognosis of patients with EOC.

Natural orifice transluminal endoscopic surgery (NOTES) has received considerable interest in recent years as a novel surgical technique. Here, we aim to review the current progress on NOTES, particularly focusing on the advantages and complications related to NOTES, the recent advances of surgical approaches, new instruments for closure of the natural orifice incision, and the newly developed platform for NOTES. Finally, we make a prediction of the conceivable applications of NOTES on human subjects.
