Objective To observe the relationship between zonula occludens protein subunit 1 (ZO-1) and the regulatory effect of vasodilator stimulated phosphoprotein (VASP) on the intestinal barrier function in rats of hemorrhagic shock (HS). Methods The intestinal barrier function was reflected by the hematoplasma D-lactic acid content,and the mucous membrane of small intestine from HS rats at different time after shock (1,2 and 4 h) were adopted to determine the expressions of VASP,phospho-VASP and ZO-1. cAMP,the agonist of VASP phosphorylation,was employed to observe the change of the above mentioned molecules and the intestinal barrier function following HS. Results (1) VASP expression of small intestine mucous membrane was decreased significantly after HS (P

Objective To observe the effects of vasedilator stimulated phosphoprotein (VASP) of small intestine mucous membrane on the intestinal barrier dysfunction during hemorrhagic shock (HS) in rats. Methods Forty Wistar rats were divided into normal group, HS 1 hour, HS 2 hours and HS 4 hours groups, as well as HS 2 hours + cyclic adenosine monophosphate (cAMP) treatment group. The activity of sermn diamine oxidase (DAO), content of hematoplasma D-lactic acid of each group were determined, and their relationship with the expression of VASP was analyzed. Results The expression of VASP was increased, serum DAO activity and hematoplasma D-lactic acid content were decreased by cAMP in rats at 2 hours after HS. There were differences upon the levels of VASP expression, DAO activity and hematoplasma D-lactic acid content between HS 2 hours group and HS 2 hours + cAMP treatment group ( t = 18.62, 9.28, 2.83, P < 0.05 ). The serum DAO activity increased while VASP expression decreased significantly after HS, which showed an obvious negative correlation between the two indexes (r=-0.95, P<0.05). Conclusions The decrease of VASP contributes to the intestinal barrier dysfunction after HS in rats, while the intestinal barrier dysfunction can be alleviated by cAMP.

Fever and sweating are the most common clinical symptoms, which are important parts in the inquiry of traditional Chinese medicine (TCM). Just as Zhang Jingyue said, Firstly inquire for cold and heat and secondly in-quire for the sweating. It placed both symptoms as priorities in the collection of disease history. In the clinical prac-tice, febrile diseases refer to acute exogenous diseases infected by warm evil with the main symptom of fever. And fever is almost throughout the entire process of febrile diseases. It is also known as Han-Bing for the visible varia-tion of sweating in its entire disease process. It is important to identify the abnormality of sweating for the determina-tion of the severity febrile diseases and the level of body fluid shortage. Therefore, two main symptoms for the diag-nosis of febrile diseases are particularly prominent and important. The reasons of sweating and fever in febrile dis-eases have been explored so much but the relationship between them is less which is extremely essential to learn more about febrile diseases. So we are expected to explore this topic to make better use of theories of febrile dis-eases.

Objective: To propose reasonable suggestions to promote the standardization of clinical studies by reviewing the systematic reviews and meta-analyses of acupuncture-moxibustion treatment of essential hypertension (EH). Methods: Computer retrieval was conducted through Excerpta Medica Database (EMBASE), PubMed, China National Knowledge Infrastructure (CNKI), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), and Wanfang Academic Journal Full-text Database (Wanfang) to collect systematic reviews and meta-analyses relevant to treating EH with acupuncture-moxibustion therapy. The time range was from the database's inception till July, 2020. The studies were screened based on the inclusion and exclusion criteria and then data-extracted. The study's quality and evidence ratings were performed by referring to the preferred reporting items for systematic review and meta-analysis (PRISMA), a measurement tool to assess systematic reviews 2 (AMSTAR 2), and the grading of recommendations, assessment, development, and evaluation (GRADE). Results: A total of 14 studies, 10 in Chinese and 4 in English, published between 2012 and 2019, were included, involving 70 outcome measures. The methodological quality was rated as critically low, the reporting was relatively complete or had certain flaws, and the evidence strength was rated as low or very low. Conclusion: Regarding the acupuncture-moxibustion treatment of EH, the methodological quality and outcome measure evidence of existing systematic reviews and meta-analyses are relatively low, and the reporting quality also expects further improvements.

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.

Objective: To understand the current situation of trauma treatment and evaluate the training effect and influencing factors of "China Trauma Care Training (CTCT)" by investigating the trainees who participated in the course. Methods: A total of 1660 trainees who participated in CTCT training from May 2017 to May 2018 were selected as the subjects of this study. Through questionnaires, the general information (gender, occupation, professional title, discipline source, length of time engaged in trauma treatment), the situation of trauma treatment in their hospitals (hospital level, trauma treatment mode, number of severe trauma cases each year), the recommended model of trauma treatment, learning methods of trauma treatment knowledge, and the trauma training interval were obtained. The trainees took tests before and after the training, and the test results were used to evaluate the training effect and analyze the influencing factors. Results: (1) There were 1 230 males (74.10%), 1 356 physicians (81.93%), 1 247 with intermediate title or lower levels (75.12%), 756 from emergency department/emergency surgery (45.54%), and 899 who were engaged in trauma treatment for more than five years (54.16%). (2) There were 1 068 trainees from tertiary hospitals (64.34%). The main mode of severe trauma treatment in hospitals was "emergency+ consultation+ triage" (1 198 trainees, 72.17%). A total of 1014 trainees treated less than 200 severe trauma patients each year (61.08%). A total of 1210 trainees recommended emergency/emergency surgery (72.89%) and 350 trainees recommended trauma surgery/trauma hospital (21.08%) as the main mode of treatment. (3) There were various approaches to acquire trauma treatment knowledge, including 1 029 person-times (61.99%) through department internal guidelines, 924 person-times (55.66%) through case discussion, 879 person-times (52.95%) through self-teaching, 767 person-times (46.20%) through lectures, 382 person-times (23.01%) through trauma courses and 285 person-times through further studies at home and abroad (17.17%). A total of 951 trainees recommended 1-2 years as the training interval (57.3%). (4) The average test score before training was (67.5±14.5)points, which were influenced by the hospital level, discipline source, title of trainees, length of time engaged in trauma treatment, and amount of severe trauma cases each year in their hospitals. The hospital level and discipline source were the main effect factors. (5) The average test score after training was (83.8±11.6)points, which was significantly higher than that before training (P<0.01), and the scores of trainees in different subgroups were all improved. The main factors influencing the test score included hospital level, number of severe trauma cases each year, discipline source, professional title, number of severe trauma cases each year treated in the hospital. The major effect factor was the amount of severe trauma cases each year. Conclusions The main mode of trauma treatment in hospitals involved in this study is "multi-disciplinary consultation+ decentralized treatment" . Few trainees have received systematic trauma treatment training, and their trauma treatment knowledge level and the test scores before training is influenced by hospital level, the case number of severe trauma treatment, discipline source, and trainees’qualifications. After the standardized and standardized trauma treatment training course "CTCT" , the scores of students from different backgrounds have been significantly improved, and the gap between students has been significantly narrowed.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously，the patients with traumatic rib fractures were mostly treated non-surgically，of which 50%，especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities，being unable to retain a full-time job. In the past two decades，thanks to the development of internal fixation material technology，the surgical treatment of rib fractures has achieved good outcomes. However，there are still some problems in clinical treatment，including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans，and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore，the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association，in conjunction with national multidisciplinary experts，formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures（2021）following the principle of evidence-based medicine，scientific nature and practicality. This expert consensus puts forward some clear，applicable，and graded recommendations from aspects of preoperative imaging evaluation，surgical indications，timing of surgery，surgical methods，rib fracture sites for surgical fixation，internal fixation methods and material selections，treatment of combined injuries in rib fractures，in order to provide references for surgical treatment of traumatic rib fractures.

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.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
