ABSTRACT
During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
ABSTRACT
Objective:To explore the possibility of using Lopinave/Litonawe (LPV/r) as treatment for novel coronavirus 2019-nCov pneumonia by systematically review earlier coronavirus studies.Methods:Systematically retrieve relevant clinical studies from Chinese and English databases such as CNKI,VIP, Wangfang Data,CBM,PubMed, Web of Science,EMBASE. In addition, information from Chinese biomedical journals, WHO, US CDC, Chinese CDC websites and the references from published relevant articles were retrieved. The inclusion period is from January 2003 to January 24, 2020. The criteria for inclusion are: (1) studies that aim to compare LPV/r and placebo/standard for SARS, MERS; (2) studies that include at least one clinical outcome; (3) studies with diagnosis criteria meeting WHO requirement on SARS or MERS; (4) data from multiple reports but originated from one study, where we extract information from all reports; (5) guidelines, includes: national or academic guidelines/experts 'consensus. The exclude criteria are: 1) only have abstracts but no full information; 2) in vitro studies.

ABSTRACT
The digestive tract is a target organ attacked by COVID-19. It is also the earliest affected organ other than the lung and must bear side effects from the anti-virus chemotherapy such as LPV/r. In this article, we aim to provide practical recommendations for a nutritional and metabolic management strategy for severe corona virus disease-19 (COVID-19) patients. These recommendations are based on the newest pathophysiological findings on the risk factors of malnutrition for COVID-19. We also systematically retrieve literatures on nutritional therapy for acute lung injuries from international and Chinese databases according to evidence-based principles. Our suggestions are: 1) Physicians should be mindful of gut injury when they focus on respiratory support, by monitoring and managing the nutritional status; 2) Periodical and dynamic nutritional risk evaluation is needed; 3) For severe patients, the feeding target of calorie and protein should be down-regulated; 4)The using of ω-3 fatty acids products should be in accordance with pharmacological indications; the forms and dosage should be determined individually.

ABSTRACT
The advantages of 5G communication, including large bandwidth, low latency and wide connection, and rapid transmission, have proved to be vital in facilitating emergency medical rescue. On June 17th, 2019, an earthquake occurred in Channing, Yibin, Sichuan Province. Sichuan Provincial People’s Hospital initiated the Emergency Medical Rescue System for the rescue operation in the disastrous area. This was the first use of 5G emergency medical rescue worldwide. Remote consultations, injury assessments and helicopter transfers were carried out for the critical patients. Our rescue system have been effective and efficient in rapid responding, information transmission and the coordination of medical resources, which has led to the best possible medical decisions and treatments. However, there were challenges found in the application of this system: the stability of 5G signal, the optimization of the configuration of 5G ambulances, and the survival rate and self guarantee in the field. In conclusion, this practice of 5G emergency medical system provides a new paradigm and valuable experiences for the improvements in disaster rescue in China and worldwide.

ABSTRACT
Objective One of the major challenges to emergency department is to provide high quality and time sensitive service under limitation of human/material resources,along with patients population with extremely complex conditions.We presented a study that based on a big data got from real world and used wavelet transform technique to analyze time-dependent diseases spectrum patterns and evolution patterns,which will provide solid methodological support for optimizing resources configuration for acute care surgery service.Methods Record data of patients admitted to acute care surgery from 2007-2014 were collected by using data management tool (Avaintec,Helsinki,Finland).The data were cleansed and were transformed to continuing spectrum according to time series of admission time points (per 9 hours).Matlab was used for wavelet transform,and applied five levels of wavelet decomposition and calculated the best decomposition levels by K-mean algorithm for each level.Then we used aprori algorithm for data mining (frequent patterns mining).Results A total of 23 795 cases were enrolled and acute abdomens were made up biggest proportion of admission.Meanwhile,it is found that the spectrum of acute care surgery admission frequency was a complex rising sequence.After wavelet decomposition,signal wave A reflexed trends evolution in a given time scale,and noise wave D reflexed minutia at relevant time scale.In another words,a principal wave A1 represented fluctuation at a cycle of 16 days.Noise wave D1 reflected intensity level in this 16 days' cycle.For example,the 5 · 12 episodes of massive earthquake in 2008 were included in the study,it is found that a significant noise wave at D3 level that indicated a 4 days' cycle.Clinically,it indicated explosive admissions to acute care surgery in 4 days.Conclusions The admission spectrum to acute care surgery is a phenomenon of multi-scale.Based on wavelet decomposing,we can easily analyze the rule of admission spectrum from electronic records of patients and can be used for optimization the emergency medicine resources.
ABSTRACT
Objective To evaluate systematically whether administration of hypertonic saline transfusion affects clinical outcomes with compared to standard fluid in the early stage of resuscitation for traumatic shock patients.Methods Seven English and Chinese routine biology and medicine databases were searched for randomized controlled trials (RCTs) published from January 2002 to August 2012,and established inclusion and exclusion criteria to evaluate these RCTs.The quality assessment was based on the Cochrane Handbook for Systematic Reviews of Interventions Version 5.0.1 and Jadad' s score scale.RevMan 5.0 statistical software was used for meta-analysis.Results After evaluated 211 related literatures,five RCTs met all the inclusion criteria and were enrolled for meta-analysis.The meta-a nalysis demonstrated that early hypertonic transfusion did not decrease short-term (first 48 hours after admission) mortality (RR =1.04,P =0.74); nor did it decrease later-term (7day to 3month after injury) mortality (RR =0.97,P =0.72).It also did not decrease the total volume of fluid and blood transfusion required during the first day (P =0.38).Similarly,it did not affect the incidents of infections (RR =1.04,P =0.70),the length of stay in ICU (P =0.2) and total length of stay in the hospital.Conclusions Compared to standard fluid,there was no advantage on mortality and hospital infection by using hypertonic supplement transfusion in the early stage of resuscitation for traumatic shock patients.Hypertonic transfusion did not have any significant effect on the volume of total fluid and blood transfusion required the first day,and no trend of reduction for the length of ICU and hospital stay.Further well-designed randomized controlled trials are needed to demonstrate the cost effectiveness of hypertonic transfusion to traumatic shock patients while in ICU.
ABSTRACT
For the first time ever, the scientists of J. Craig Venter team have created actual self-replicating synthetic life. The research was just published in the Journal of Science on May 20, 2010. Although this news immediately brings the worry about the possible potential threat to biosecurity and biosafety as well as the ethical disputes, it yet indicates that mankind have made a new step forward in synthetic biology. In the time of post-genome era, we believe the advancement of synthetic biology that might affect or change the future life of human being will be widely used in energy, environment, materials, medication and many other fields.

Throughout human history, pandemic bacterial diseases such as the plague and tuberculosis have posed an enormous threat to human beings. The discovery of antibiotics has provided us with powerful arsenal for the defense against bacterial infections. However, bacteria are acquiring more and more resistance genes to shield off antibiotics through mutation and horizontal gene transfer. Therefore, novel antibiotics must be produced and the arms race between bacterial pathogens and antibiotics is becoming increasingly intense. Recently, researchers have found that plasmids carrying a new metallo-beta-lactamase gene, blaNDM-1, and many other antibiotics resistance genes can easily spread through bacterial populations and confer recipient stains resistance to nearly all of the current antibiotics. It is a threat to the human health and a great challenge for our medical science, which we are facing. We need to find new ways to fight and win this arms racing.
