Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To investigate the effect of left colonic artery (LCA) preservation on rectal cancer patients' short-term postoperative anal function and quality of life.Methods:Two-hundred ninty-two patients with rectal cancer at the Department of Gastrointestinal Surgery of Peking University First Hospital between Jan 2022 and Dec 2023 were enrolled . The patients were divided into two groups according to whether the LCA was preserved during surgery or not. The LARS scale and EORTC QLQ-CR29 quality of life questionnaire were used to assess postoperative anal function and quality of life.Results:There were no significant differences between the two groups in terms of the amount of surgical blood loss and the number of lymph node dissections in the root No. 253 group and the time to postoperative voiding (all P>0.05). However, the LARS scores at 1 and 3 months postoperatively were significantly lower in the preserved LCA group than in the LCA nonpreserved group, especially for gas incontinence, loose stool leakage, and number of bowel movements (all P<0.05). The EORTC QLQ-CR29 scores showed that the LCA preserved group recovered significantly better than the non-preserved group in terms of postoperative voiding dysfunction ( P=0.007), urinary incontinence ( P=0.006), mucus discharge ( P=0.009), and fecal incontinence symptoms ( P<0.001). Male sexual dysfunction recovery was quicker in the preserved LCA group ( P=0.043), but there was no significant difference between the two groups at 3 months postoperatively( P>0.05). Conclusion:Preservation of the left colonic artery in low anterior resection of rectal cancer helps to reduce the incidence of postoperative low anterior resection syndrome, improve genitourinary symptoms, and improve patients' quality of life.

Objective:Analyze the risk factors of gastrointestinal perforation caused by foreign body and summarize the experience of surgical treatment of foreign bodies.Method:From Jan 2008 to Dec 2023, 89 patients with foreign bodies in the digestive tract were admitted to the Department of Gastrointestinal Surgery, Peking University First Hospital. Relevant data were collected and binary logistic regression was used to analyze the independent risk factors for intestinal perforation, resection and anastomosis of intestine or enterostomy/colostomy.Results:The mean age of 89 patients was (60.1±16.2) years old, 65 patients (73%) had unintentionally ingested foreign bodies. The most common foreign bodies were jujube pits (40 cases). Thirty-nine patients diagnosed with gastrointestinal perforation. Binary Logistic regression analysis showed that the total number of leukocytes ( OR=4.085, 95% CI: 1.214-13.745, P=0.023), sharp foreign body ( OR=26.124, 95% CI: 5.194-131.392, P<0.001), and the location of foreign body ( OR=3.980, 95% CI: 1.178-13.465, P=0.026) were the independent risk factors for gastrointestinal perforation. Thirty-three patients underwent gastrointestinal repair surgery, and 36 patients underwent resection and anastomosis of intestine or enterostomy/colostomy. Binary Logistic regression analysis showed that the foreign body located in the colorectum ( OR=71.928, 95% CI: 4.646-1 113.479, P=0.002) and the length of the foreign body ≤2.5 cm ( OR=5.791, 95% CI: 1.606-20.882, P=0.007) were the independent risk factors for resection and anastomosis of intestine or enterostomy/colostomy. Conclusions:Leukocyte count ≥10×10 9/L, sharp foreign body, and location of foreign body are independent risk factors for gastrointestinal perforation. Foreign body located in the colorectum and foreign body length ≤2.5 cm are risk factors for resection and anastomosis of intestine or enterostomy/colostomy.

Objective:To evaluate whether additional radical surgery is necessary following non-curative endoscopic resection of early colorectal cancer.Method:Clinicopathological data in 104 patients following non-curative endoscopic resection of early colorectal coucer at the Department of General Surgery, Peking University First Hospital between Jan 2011 and Dec 2021.Results:Lymph node metastasis and/or residual cancer was found in 23 patients (22%), including 12 cases of lymph node metastasis, 7 cases of residual cancer and 4 patients with both residual cancer and lymph node metastasis. Univariate analysis indicated that vascular infiltration, positive vertical margin, and female gender were risk factors for lymph node metastasis. Risk factors for residual cancer were tumors ≥2 cm in size, negative lift sign, infiltration depth of ≥1 000 μm, and positive horizontal and vertical margins. Multivariate Logistic regression analysis revealed that vascular invasion, positive vertical margins, and being female were independent risk factors for lymph node metastasis, while positive vertical margins was independent risk factor for residual cancer. Salvage surgery lasted for a median of 184 (156-233) minutes, with an estimated blood loss of 50 (20-100) ml and an average postoperative hospital stay of 9 (8-11) days. Seven cases of Clavein-Dindo Ⅱ or higher complications were observed, including pulmonary embolism in 1 case , anastomotic leakage in one, lymphatic fistula in one, bowel obstruction in 2 cases and urinary tract infection in 2 cases.Conclusion:Salvage surgery is mandatory for early endoscopic non-curative resection of colorectal cancer.

Objective To explore the clinical effect of floating acupuncture on military training injuries,so as to provide reference for the prevention and treatment of military training injuries.Methods A total of 300 patients with ankle,knee,hip,lower back,neck and shoulder diseases caused by military training were divided into two groups.One group was treated with floating acupuncture,and the other group(control group)was treated with traditional physical therapy,medicine and acupuncture.Visual analogue scale(VAS)and Functional Movement Screening(FMS)were used to assess pain and functional movement before and after treatment,respectively.Results After treatment,VAS scores in the floating acupuncture subgroups were significantly lower than those in the control group,and FMS scores in the floating acupuncture subgroups were significantly higher than those in the control group(all P<0.05).Conclusion Floating acupuncture has significant effect on ankle,knee,hip,lower back,neck and shoulder diseases caused by military training,and it is worthy of popularization.

Objective:To explore the relationship between relapse tendency and childhood maltreatment in methamphetamine-dependent youths,and the role of impulsivity and quality of life in the relationship.Methods:To-tally 287 methamphetamine-dependent youths(160 females,127 males)were selected in compulsory drug rehabili-tation centers.The Relapse Tendency Questionnaire(RTQ),Childhood Trauma Questionnaire-Short Form(CTQ-SF),Barrett Impulsivity Scale(BIS-11)and Quality of Life for Drug Addicts(QOL-DA)for Drug Addicts were used to conduct the survey.SPSS macro program PROCESS was used to test the mediating role.Results:The BIS-11 total scores acted as a partial mediator between the total scores of CTQ-SF and RTQ,with an effect value of 0.03(95％CI:0.01-0.05),the QOL-DA total scores acted as a full mediator between the total scores of CTQ-SF and RTQ,with an effect value of 0.05(95％CI:0.02-0.08),and the scores of BIS-11 and QOL-DA acted as chain mediators between total scores of CTQ-SF and RTQ,with an effect value of 0.01(95％CI:0.00-0.03).Conclusion:Childhood maltreatment,impulsivity,and quality of life may be associated with relapse tendencies in methamphetamine-dependent youths.

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.
