A discussion is made on the risk perception,lawful practice,team building, infrastructure,partnership,and operational mechanism of aviation medical rescue by hospitals,along with proposals for stakeholders and authorities for reference.

General hospitals have an important rescue mission when fortuitous mass casualties occur as a result of natural or man made disasters. The paper argues that in order for general hospitals to constantly improve their emergency rescue capabilities so as to play a better role in rescue and relief work, it is imperative for them to strengthen the construction of the emergency department, amplify various rules and regulations, improve the quality of the chief operator on duty, formulate emergency rescue plans, and enforce the sense of cooperation.

Pre-bospital Emergency Medical Care (EMC) is special medical care based on emergency medical facilities, mainly providing emergency care for patients who need immediate and intensive care out of the hospital Over many years of practice, both patients and medical staff have realized that immediate access to emergency treatment is essential; quality of care is fundamental and effect is ultimate. Therefore, there is an urgent need to establish an overall, objective, and feasible evaluation system for the purpose of improving quality of care. In the present article, the author has designed a framework of quality evaluation system for pre-hospital EMC by means of formulating investigation plans and analyzing the indicators that reflect the quality of care being evaluated so as to promote the implementation of the evaluation system.

With the rapid development of urban construction in China,the urban emergency medical system construction,especially the network construction,which is related to people's safety and security,is of great realistic significance.The author suggests that the urban emergency medical network construction should be strengthened to improve the response speed as well as rescue result by taking the following measures:(1)strengthening network construction to shorten the radius of rescue;(2)implementing strict scientific management to improve response speed;(3)popularizing emergency medical knowledge to extend medical insurance;(4)innovating emergency mode to give priority to ambulance vehicles;(5)establish special service team to cope with unexpected events;(6)setting special lane to ensure unhindered access.

Earth is home not only to humans, but also to everything, including viruses. In the current globalization of coronavirus disease 2019 epidemic, the fluctuations of novel coronavirus makes epidemic prevention and control work normal, and the initiator of the accident, 2019 novel coronavirus, will coexist with human society for a long time. How we can coexist peacefully with them in this state is worth to thinking and studying.

The epidemic caused by 2019 novel coronavirus has been highly concerned by the international community including World Health Organization (WHO). This is an endless battle against human life and health. Never forget the past, the teacher of the future. When you think hard, draw inferences from one instance. Many phenomena and problems in the work of epidemic prevention, control and treatment are worthy of our deep reflection. We should use scientific thinking and dialectical materialism to make a practical and realistic summary. The purpose is to win the battle as soon as possible, and more importantly, to avoid repeating the same mistakes and prevent trouble before it happens.

Objective To study the feasibility and curative effect of laparoscopic radical resection of rectal carcinoma. Methods Sixty-two cases were enrolled in this study between Feb 2003 and Mar 2005, including 32 cases undergoing laparoscopic radical resection (19 Dixon and 13 Miles) , and 30 cases undergoing open radical resection (22 Dixons and 8 Miles). Results The mean operation time of laparoscopic group was 195 min, and open group was 156 min (P 0. 05 ). The GI and urination function of laparoscopic group recovered faster than open group ( evacuated was 2. 7 days vs. 3. 7 days, P

Aviation medicine is being recognized as a rising star and an indispensable part of the "trinity"medical emergency network composed of land, water and air. The unparalleled mobility and traffic advantages of aircraft, especially rotorcraft (helicopter), are playing an increasingly important role in rescuing the dying and wounded, especially the critical patients, and thus derive a new medical operation mode. How to adapt to the development of the situation and the progress of the times, give full play to the advantages of aviation medical care? The key factors are improvement of the level of service efficiency, strength of learning, practice courage, innovation, and good at summing up to keep pace with the times.

[Objective] To explore the techniques of hand-assisted laparoscopic splenectomy plus portozygos disconnection procedure. [Methods] 18 patients with portal hypertension were operated by hand-assisted laparoscopic splenectomy plus portozygos disconnection. [Results] The operations were completed successfully. The mean operative time was 180(150～260) minutes, the mean blood loss estimated was 540(200～2 000) mL, the mean weight of spleen was 910 (500～2000) g and the mean length of hospital stay was 9.7 (8～18) days after operation. All patients had recovered rapidly and suffered less pain and only 5 patients needed analgesic. The mean recovery time of the bowel function was 52(24～74) hours. The hand incisions healed well, and only one occurred complications and another suffered death. [ Conclusions ] Hand-assisted laparoscopic splenectomy plus portozygos disconnection procedure is to be feasible and safe, and has the merits of minimally invasive surgery.
