RESUMO
Objective@#To analyze the risk factors of cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.@*Methods@#530 patients with esophageal cancer underwent thoracoscopic-lapacoscopic esophagectomy at the Cancer Hospital, Chinese Academy of Medical Sciences from Jan 2011 to Dec 2015. The demographic, surgical and clinical data of patients were retrospectively analyzed. Multivariate logistic regression was used to evaluate risk factors of cervical anastomotic leakage in these patients.@*Results@#A total of 530 patients undergoing thoracoscopic-lapacoscopic esophagectomy were enrolled in this study. There were 421 males and 109 females. The mean age was (59.40±8.08) years old, and 91 patients with cervical anastomotic leakage. Sigle factor analysis revealed that the risk grading by American Society of Aneshesiologists, previous history of chest surgery, respiratory comorbidity, diffusion capacity for carbon monoxide of the lung, operation time, anastomosis, average days of postoperative hospitalization, death within 30 days after surgery, respiratory complications, pleural effusion or empyema, and poor healing of the incision were statistically associated with cervical anastomotic leakage (all P<0.05). Multivariate analysis showed that previous history of chest surgery, hepatic insufficiency, manual anastomosis, prolonged postoperative hospitalization, and poor healing of the incision were independent risk factors for cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy (all P<0.05).@*Conclusions@#Previous history of chest surgery, hepatic insufficiency, poor healing of the incision, manual anastomosis and prolonged postoperative hospitalization were significantly associated with cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. It′s important to strengthen perioperative nursing and surgical techniques to prevent anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.
RESUMO
In the past two decades,the United States made an impressed progress in the prevention and control of cancer that the overall morbidity and mortality of cancer had shown a downward trend, while China had seen an opposite trend. Cancer, one of the major public health concerns in China, has imposed an enormous burden onthe society and individuals. Therefore,in order to scientifically formulate cancer prevention and control policies, it is essential to make a comprehensive understanding of the practical experience in the field of cancer prevention and control from the United States. This article reviews the relevant literature on cancer trends as well as the prevention and control strategies in the United States,depictsthe cancer epidemic situation in the United States in the past 30 years, and summarizes the influencing factors, strategies and intervention experiences that lead to the improvement of cancer epidemic. It highlights the policy support, surveillance and intervention adopted by the United States for the cancer prevention and control. This article is expected to provide some implications and reference for the cancer prevention and control in China.
RESUMO
Gene editing technology has a broad development prospect in medical research and appli-cation,and it is a frontier hot spot in the field of biomedical research worldwide,especially in the field of be-havioral medicine,making it possible to treat and prevent major diseases such as brain diseases,neurodegen-erative diseases and behavioral psychology diseases. But we must recognize that gene-editing technology poses new threats to bio-security while benefiting humanity. This paper summarizes the development and application prospect of gene editing technology in the field of behavioral medicine,summarizes the ethical and relevant institu-tional problems and international regulatory policies faced by the rapid development of gene editing technology, and finally puts forward relevant regulatory suggestions for the development of gene editing technology.
RESUMO
In Scientific Research Institutions,it has great significance of the S&T resources archiving and sharing to promote the deepening reform of S&T system and realize the great leap-forward development of S&T innovation.In this paper,we conduct empirical analysis on the conditions of S&T resources archiving and sharing in a Medical Organization in Beijing.The results show that the S&T resources archiving and sharing in Medical Organization have achieved initial success,however,the achievements are not ideal and the waste and shortage of S&T resources still coexisted.In view of the deficiencies of the idea,system,laws and regulations of S&T resources archiving and sharing,this paper puts forward corresponding countermeasures and suggestions.
