Objective To explore the biomechanical safety of applying traditional Chinese orthopedic manipulation therapy after anterior cervical discectomy and fusion(ACDF)surgery,so as to provide a theoretical basis for clinical treatment in biomechanics.Methods Based on CT data,a three-dimensional finite element model of the normal C0-T1 cervical spine was established,and an ACDF postoperative finite element model of the C5-6 segment was constructed on this basis.Cervical spine rotation manipulation was simulated at the C4 and C7 segments of both models,and the von Mises stresses of the vertebral body,bilateral facet joints,intervertebral discs,and internal fixation system under manipulation loading of the C4 and C7 segments in both models were compared and analyzed.Results When the C4 segment was manipulated,the stress on the C5,C6,and C7 vertebral bodies in the ACDF postoperative model decreased by 12.3％,11.5％,and 26.4％,compared to the normal model.The stress on the left facet joints of the C4-5,C5-6,and C6-7 segments decreased by 12.3％,58.8％,and 15.4％,and the stress on the right facet joints decreased by 16.6％,92.1％,and 17.2％.The stress on the C4-5 and C6-7 segments decreased by 13.2％and 4.0％,while the maximum stress of the fusion cage,titanium plate,and screws in the C5-6 segment were 9.349,111.9,and 300.8 MPa.When the C7 segment was manipulated,the stress on the C4,C5,and C6 vertebral bodies in the ACDF postoperative model increased significantly compared to the normal model,especially the C5 vertebral body,with an increase of nearly 18 times.Except for the stress on the left facet joint of the C4-5 segment increased by 57.7％,the stress on the bilateral facet joints of other segments generally decreased,but the stress on the C4-5 and C6-7 segments increased by 43.2％and 21.7％and the stresses on the fusion cage,titanium plate,and screws in the C5-6 segment were 2.926,205.4,and 256.2 MPa.Conclusions The safety of performing manipulation on the upper vertebral body of the fusion segment after ACDF surgery is relatively high,but performing manipulation on the lower vertebral body of the fusion segment may lead to stress concentration and increase the risk of injury.When postoperative conservative treatment is implemented,the manipulation safety and indications should be considered to avoid operations in high-risk areas,and more precise and safe manipulation intervention treatment should be implemented based on the specific postoperative biomechanical state of the patient.

Objective To explore the biomechanical characteristics of different types of lumbar disc herniation(LDH),and provide a theoretical basis for the clinical classification,diagnosis,and treatment of LDH.Methods A normal lumbar spine model with spinal nerves and four types of LDH models(central type,paracentral type/lateral recess type,intervertebral foramen type,extreme type)were constructed,and the biomechanical characteristics of the intervertebral discs and nerve roots in neutral posture and under six degrees of freedom conditions were analyzed.Results In neutral position,the stress of normal intervertebral disc was carger than that of the herniated intervertebral disc,and the stress ratio of annulus fibrosus and nucleus pulposus in normal model was greater than that of annulus fibrosus and nucleus pulposus in herniated models.In neutral position,the disc stress was mainly concentrated at the incisor between the protrusion and normal part,and recruitment occurred at outer edge of the disc.In flexion and extension position,the stress of the herniated intervertebral disc shifted to the right side.The maximum stress of herniated intervertebral disc appeared during right flexion,and the nerve root stress on the right side was carger than that on the left side.The stress of the herniated intervertebral disc during right rotation was slightly lower than that during right flexion,and the stress of nerve root on the right side was smaller than that on the left side.Conclusions The intervertebral disc is important in maintaining lumbar dynamic and static stability and flexibility.Different positions have an obvious effect the intervertebral disc stress.For patients with LDH,forward bending,flexion of the affected side and large extension should be avoided.Appropriate rotation of the affected side can help relieve the symptoms of nerve root compression.

Objective To review the factors affecting the occurrence of incontinence dermatitis in adults and severe patients,and provide clinical theoretical guidance for clinical nurses to reduce the incidence of incontinence dermatitis.Methods The literatures on the influencing factors of incontinence-associated dermatitis in adult patients with intensive care were searched in PubMed,Web of science,CINAHL,Embase,Cochrane Library,CNKI,Wanfang,Vip and SinoMed.The search period was from the establishment of the database to December 31th,2023(March 31,2025 updated).Results A total of 19 literatures were included,and the influencing factors of IAD mainly included 5 aspects:incontinence type,disease status,medication use,risk assessment and other factors.Conclusion There are many factors affecting the occurrence of incontinence-associated dermatitis in adult patients with intensive care,and nurses should implement diversified skin intervention strategies to reduce the incidence of IAD in adult patients with intensive care.

Objective To summarise the best evidence on non-pharmacological management in children and to provide evidence-based guidelines for clinical practice.Methods With the 6S evidence pyramid model,a comprehensive and systematic search across multiple databases was conducted,including UpToDate,BMJ Best Practice,Joanna Briggs Institute of Australia's Centre for Evidence-based Health Care Database(JBI),National Guideline Clearing-house(NGC),Guidelines International Network(GIN),The National Institute for Health and Care Excellence(NICE)website,Scottish Intercollegiate Guidelines Network(SIGN),American Dental Association,Canadian Dental Association,Cochrane Library,CINAHL,Embase,PubMed,SinoMed,CNKI and Wanfang Data.The search focused on literature pertaining to the improvement of non-pharmacological strategies for compliance with paediatric oral treatment,encompassing clinical decisions,evidence summaries,clinical guidelines,systematic reviews,expert consensus,best practices,and randomised controlled trials.The literature search encompassed all available publications from the inception of databases up to 5th November,2023.A quality assessment of the literature was independently conducted by four researchers trained by evidence-based nursing courses,while evidence extraction and summarisation were handled by two researchers.Results A total of 16 papers were included,comprising 2 clinical decisions,2 evidence summaries,3 guidelines,5 systematic evaluations,1 best practice,2 expert consensus and 1 randomised controlled trial.Nineteen pieces of evidence were extracted and classified into six categories:outpatient setting,assessment and management of children,pre-treatment non-pharmacological management,in-treatment non-pharmacological management,post-treatment non-pharmacological management and training and assessment.Conclusion This study summarises the best evidences for non-pharmacological management aiming to improve the oral treatment compliance in children.Healthcare providers can facilitate the translation of this evidence into clinical practice by considering the specific clinical context as well as factors such as the age and psychological characteristics of children.

Objective:To deeply understand the experience of neurosurgery nurses on the lack of perioperative nursing for intracranial tumors patients, so as to provide reference for reducing the lack of nursing and improving the quality of nursing and patients′ medical experience.Methods:From December 2023 to February 2024, the neurosurgical nurses of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were selected by the purpose sampling method with maximum differentiation. Semi-structured interviews were conducted with phenomenological research methods. The interview data were transcribed, coded, categorized and described.Results:A total of 17 neurosurgical nurses were enrolled, including 6 males and 11 females, aged 24-45(33.29 ± 6.74) years. Three themes of perioperative nursing lack experience of neurosurgery nurses were obtained, including nursing lack experience (lack of safety nursing, lack of timely nursing, lack of high efficiency nursing, lack of effectiveness nursing, lack of fair nursing, and lack of patient-centered), the physical and mental effects of nursing lack on nurses (impacts of lack of nursing on nurses′ physiology and psychology), and reasons for lack of nursing (personnel, equipment, materials, organization management, environment).Conclusions:Neurosurgical nurses lack of perioperative nursing for patients with intracranial tumor, which has a certain impact on the physical and mental health of nurses, suggesting that neurosurgical nurses should attach great importance to the lack of nursing for patients with intracranial tumor and formulate a scientific and effective management system.
