Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To analyze the efficacy of autologous tissue repair for rectocele through the perineal approach in treating constipation and fecal incontinence in patients.Methods From January 2021 to November 2022,23 female patients with symptomatic rectal protrusion were treated with perineal autologous tissue repair.Preoperatively and at 12 months postoperatively,the Cleveland Clinic Constipation Score(CCCS),Cleveland Clinic Incontinence Score(CCIS),and Patient Assessment of Constipation Quality of Life(PAC-QOL)questionnaires were used to assess postoperative outcomes and quality of life.Results Among the 23 patients,with a median follow-up time of 12.6 months,CCCS decreased from 17.09±1.68 to 3.96±2.08(P＜0.05);CCIS decreased from 1.52±4.15 to 0.52±1.41(P＞0.05);PAC-QOL:physical discomfort decreased from 13.00±1.51 to 4.74±1.98;psychological discomfort decreased from 20.96±3.27 to 5.74±2.67;concern and anxiety decreased from 26.13±4.37 to 8.78±3.14;satisfaction decreased from 15.39±2.35 to 4.60±1.59(P＜0.05).All patients showed significant improvement in constipation and incontinence symptoms postoperatively,with no serious postoperative complications and a marked improvement in postoperative quality of life.Conclusion Rectocele repair with perineal approach using autologous tissue is an effective and safe method,avoiding potential potential complications associated with grafts.

Objective:To explore the effects of pre-transplant controlling nutritional status(CONUT)and post-transplant minimal residual disease(MRD)on prognosis of patients with multiple myeloma(MM)after autologous hematopoietic stem cell transplantation(auto-HSCT).Methods:The clinical data of 79 patients who received auto-HSCT from 2011 to 2020 in The First Affiliated Hospital of Chongqing Medical University were retrospectively analyzed.The patients were divided into Low-CONUT group(n=62)and High-CONUT group(n=17)according to whether the CONUT score was less than 5.The differences in clinical features,hematopoietic reconstruction,adverse reactions,efficacy and survival between the two groups were compared.In addition,the prognostic risk factors were analyzed and verified by time-dependent ROC curve.Results:The proportions of male patients and bone marrow plasma cells＞30％at initial diagnosis in High-CONUT group were both higher than those in Low-CONUT group(both P＜0.05).While,there were no significant differences in hematopoietic reconstruction and adverse reactions(＞grade 2)between the two groups.The complete response(CR)rate and CR+very good partial response(VGPR)rate before transplantation in Low-CONUT group were both significantly higher than those in High-CONUT group(both P＜0.05).After 3 months of transplantation,the CR+VGPR rate still remained an advantage in Low-CONUT group compared with High-CONUT group(P＜0.01),but CR rate did not(P＞0.05).The overall survival(OS)and progression-free survival(PFS)in Low-CONUT group were both superior to those in High-CONUT group(both P＜0.05).Low CONUT score(0-4)before transplantation and negative MRD at 6 months after transplantation were favorable factors affecting OS and PFS(both P＜0.05),while the International Myeloma Working Group(IMWG)high-risk at initial diagnosis and lactate dehydrogenase(LDH)level＞250 U/L before transplantation were only risk factors for PFS(both P＜0.05).Time-dependent ROC curve analysis showed that pre-transplant CONUT score and MRD status at 6 months after transplantation could independently or jointly predict 1-and 2-year OS and PFS,and the combined prediction was more effective.Conclusion:The combination of pre-transplant CONUT and post-transplant MRD can better predict the prognosis of MM patients.

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.

Pulmonary disease is one of the major threats to human health. However, the current clinical treatment drugs for lung diseases generally have problems such as low lung delivery efficiency, fast clearance rate and obvious toxic side effects. Recently, membrane biomimetic nanocarriers have attracted more and more attention. Due to their advantages of high targeting, long cycle time, good biocompatibility and strong immune escape ability, membrane biomimetic nanocarriers have become a major research hotspot in targeted therapy of lung diseases. In this review, we discuss the main preparation methods of membrane biomimetic nanoparticles, the characteristics of membrane biomimetic nanocarriers from different cell sources and their application in the targeted therapy of lung diseases. At the same time, according to the characteristics of different membranes, the shortcomings, current technical limitations and future prospects are discussed. This review is expected to provide references for the design of membrane biomimetic nanocarriers and their potential applications in the treatment of lung diseases.

Objective:To explore the feasibility and safety of remote programming technology based on 5G cloud technology support platform in postoperative follow-up of cardiovascular implantable electronic devices(CIED).Methods:This study was a multicenter cross-sectional study. CIED patients from 12 hospitals lacking full-time follow-up specialists in Sichuan Province were enrolled from June 2021 to October 2021. All patients′ devices received remote inspecting and programming by the follow-up specialist of the remote follow-up center of the Third People′s Hospital of Chengdu through 5G cloud technology support platform. The baseline data, device alarm events, device reprogramming events, adverse reactions and satisfaction questionnaire survey results were collected.Results:A total of 195 CIED implantation patients were included, with an age of (72.5±11.3) years, including 103 males (52.6%). All patients completed remote inspecting and programming successfully, with a duration of (5.8±4.0) min. Ninety-one patients′ CIED were reprogrammed, with a total of 104 parameter adjustments. No abnormal communication or adverse events occurred. The satisfaction questionnaire showed that 97.9%(191/195) of the patients trusted or relatively trusted remote follow-up and 86.7%(169/195) of the patients were willing to choose remote follow-up mode for device management.Conclusion:The remote programming based on 5G cloud technology support platform may be feasible and safe for postoperative follow-up of CIED patients.

Objective:To observe the effect of auricular pressure beans(APN)combined with Compound Tung-Leaf Burn Oil(CTBO)on perioperative anxiety and pain in patients undergoing circumcision.Methods:This study included 100 patients undergo-ing circumcision with the disposable circumcision anastomosis stapler in our hospital from August 2023 to November 2023,of whom 50 received routine circumcision nursing care(the control group)and other 50 APN combined with compound CTBO in addition(the ob-servation group).We compared between the two groups the anxiety scores before any intervention,30 minutes before and 24 hours and 10 days after operation,the pain scores 24 hours postoperatively and at the first change of wound dressing,the frequency of 3-day post-operative sleep awakenings,the incidence of complications,and the satisfaction of the patients.Results:Totally,94 patients com-pleted the study,46 in the observation and 48 in the control group.The anxiety scores exhibited no statistically significant difference between the two groups of patients before any intervention(P>0.05),but were markedly lower in the observation than in the control group at 30 minutes before and 24 hours and 10 days after surgery(P<0.05),and so were the pain scores24 hours after surgery and at the first change of wound dressing(P<0.05),and the frequency of 3-day postoperative sleep awakenings(P<0.05).The satis-faction rate of the patients was remarkably higher(P<0.05)while the incidence of complications significantly lower in the observation group than in the control(P<0.05).Conclusion:Auricular pressure beans combined with Compound Tung-Leaf Burn Oil can ef-fectively alleviate perioperative anxiety,reduce postoperative pain and improve satisfaction of the patients undergoing circumcision.

ObjectiveTo investigate the mechanism of Akkermansia muciniphila （A. muciniphila） regulating the visceral hypersensitivity in irritable bowel syndrome （IBS） rats induced by neonatal maternal separation （MS） and water avoidance stress （WAS）. MethodsNeonatal male Sprague-Dawley rats were randomly divided into sham WAS group （blank group）， MS+WAS group （IBS model group） and A. muciniphila group. IBS model was established by MS combined with WAS in both IBS model group and A. muciniphila group. Meanwhile， the rats in the A. muciniphila group were given 1 mL 1×10⁹ CFU/mL A. muciniphila by gavage daily for 10 days. Visceral pain responses were detected by behavioral observations and abdominal withdrawal reflex scores. ResultsCompared with IBS model group， A. muciniphila group exhibited significant increase of body weight and visceral pain threshold， significantly decreased numbers of fecal particles and proportions of unformed stools， significantly higher expression levels of cannabinoid receptor type 2 （CB₂R） mRNA in colon tissues. ConclusionA. muciniphila may alleviate the visceral hypersensitivity in IBS rats by regulating the expression of CB₂R mRNA in colonic tissues.
