The relevant laws and regulations regarding the utilization of the deceased as medical research subjects are not yet fully developed in China nowadays. Taking the deceased as research subjects as a starting point， this paper discussed the definition of the deceased and the scope of their interest protection from multiple perspectives. It posited that the scope of interest protection for the deceased encompassed two components： spiritual personality interests and material personality interests represented by the remains. The spiritual personality interests of the deceased included identification information such as name， portrait， reputation， honor， privacy， and personal information， as well as medical and health information. The personal information of the deceased was not directly affected by the individual’s life and death status and remained relatively independent. In terms of ethical review， the research team approached from two perspectives： the remains and the personal information of the deceased. Based on the standard of whether the research subjects involve a human body， research with the remains of the deceased as the medical research subjects was classified as non-clinical research. According to the standard of whether a human body is clinically operated， research with the personal information of the deceased （including medical and health information） as the medical research subjects was recognized as clinical research without human research operation. This approach provided evidence for the application of existing laws and regulations in ethical review and record management. The ethical review of investigator-initiated clinical research conducted in medical and health institutions， as well as the regulatory conditions for exemption from ethical review， were examined. The forms， content， and acquisition of informed consent were summarized， and the risk-benefit characteristics of the research activity were evaluated， with a view to providing a basis for the smooth and compliant implementation of research activities involving the deceased as medical research subjects.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective To evaluate the effect of relaxation training combined with basic psychological intervention on attention deficit factor score in children with attention deficit hyperactivity disorder.Methods A total of 320 children with attention deficit hyperactivity disorder were enrolled in Anhui Children's Hospital affiliated to Anhui Medical University from April 2022 to April 2024.The children were divided into 2 groups by random number table method with 160 cases in each.The control group received basic psychological intervention and the observation group received relaxation training combined with psychological intervention.Attention deficit factor score,hyperac-tivity factor score,oppositional defiant factor score,Weiss Functional Deficit Scale(parent version)score and satis-faction were compared between the two groups.Results The Pittsburgh Sleep Quality Index(PSQI)score of the observation group was higher(17.35±1.42)than that of the control group(P＜0.05).The scores of Attention Defi-cit Hyperactivity Disorder Rating Scale-Parent Version(SNAP-Ⅳ)in observation group were lower than those in control group(P＜0.05),including attention deficit factor(14.25±1.58),hyperactivity factor(12.01±1.33)and oppositional defiant factor(9.79±1.27).There was no difference in Weiss functional deficit Scale(parent version)between the two groups before intervention,and Weiss functional deficit scale(parent version)score of the obser-vation group was higher than that of the control group after intervention(P＜0.05).The satisfaction of observation group was higher than that of control group(P＜0.05).Conclusions The effect of relaxation training combined with psychological intervention is obvious in children with attention deficit hyperactivity disorder,and the symptoms of attention deficit are significantly improved.

Objective To explore the application effect of the dual-track nursing intervention model in the treatment process of children with lobar pneumonia.Methods A total of 186 children with lobar pneumonia were selected and randomly divided into control group and intervention group u-sing a double-blind method,with 93 cases in each group.The control group received conventional nursing intervention,while the intervention group implemented the dual-track nursing intervention model on the basis of conventional nursing.This model included the establishment and training of nurs-ing teams,personalized nursing plans,health education,and psychological support.Outside the hos-pital,it emphasized family support,regular follow-up guidance,and community-based collaborative ed-ucation.Both groups received a 3-week intervention.The improvement times of clinical symptoms,hos-pital stay,pulmonary function indicators before and after nursing,treatment compliance,and family members' satisfaction with nursing were compared and analyzed between the two groups.Results The fever resolution time[(3.89±0.96)d],cough relief time[(6.21±1.34)d],disappearance time of pulmonary rales[(7.89±1.56)d],and hospital stay duration[(9.45±1.89)d]in the intervention group were all shorter than those in the control group[(5.23±1.14),(7.45±1.67),(9.32±2.01),and(11.28±2.35)d,respectively],with statistically significant differences(P＜0.05).After nursing,the forced expiratory volume in one second(FEV1)[(1.51±0.22)L],forced vital capacity(FVC)[(1.75±0.25)L],and FEV1/FVC[(94.12±5.65)％]in the intervention group were all higher than those in the control group[(1.42±0.15)L,(1.66±0.22)L,and(85.73±8.41)％,respectively],with statistically significant differences(P＜0.05).The scores for exami-nation cooperation[(23.91±3.82)points],nursing cooperation[(24.19±4.03)points],standardized medication use[(24.26±3.94)points],and rational diet[(23.77±3.62)points]in the intervention group were higher than those in the control group[(20.16±3.53),(19.64±3.46),(23.05±3.68),and(18.85±3.41)points,respectively],with statistically significant differences(P＜0.05).The satisfaction rate of family members with nursing work in the intervention group was higher than that in the control group,with a statistically significant difference(98.92％versus 89.25％,P＜0.05).Conclusion The dual-track nursing intervention model has a signifi-cant application effect in children with lobar pneumonia.It can accelerate their recovery process,improve treatment compliance,promote pulmonary function improvement,and enhance family mem-bers' satisfaction.

Objective:To investigate the efficacy of enteral nutrition in preventing bone marrow suppression in patients with nasopharyngeal carcinoma undergoing concurrent radiotherapy and chemotherapy.Methods:The clinical data of 150 nasopharyngeal carcinoma patients undergoing concurrent radiotherapy and chemotherapy treatment in our hospital from Sep 2022 to Sep 2024 were analyzed.They were divided into the conventional group(74 cases)and the enteral nutrition group(76 cases)according to different nutritional intervention plans.The conventional group received conventional nutritional therapy,while the enteral nutrition group received enteral nutrition therapy.The occurrence of bone marrow suppression,blood routine indicators,nutritional status indicators were compared,and quality of life was evaluated with cancer patient quality of life measurement scale(EORTC-QLQ-C30)and compared.Results:The total incidence of bone marrow suppression in the enteral nutrition group was lower than that in the conventional group(P＜0.05),and the degree of bone marrow suppression was milder than that in the conventional group(P＜0.05).At the end of treatment,the enteral nutrition group had higher levels of hemoglobin,granulocytes count,red blood cells count,white blood cells count,platelets count,body mass index,upper arm circumference,waist circumference,and scores of each functional domain of EORTC-QLQ-C30 compared to the conventional group(P＜0.05).Conclusion:Enteral nutrition therapy for nasopharyngeal carcinoma patients undergoing concurrent radiotherapy and chemotherapy can prevent bone marrow suppression,improve blood routine indicators and nutritional status,and enhance quality of life.
