BACKGROUND:Types II,IIA,and III of Hangman fractures often require surgical treatment,and the selection of surgical methods is controversial.Current surgeries have shortcomings such as incomplete reduction and malunion after surgery.In the early stage,our team used C2-3 lag screws combined with a bucking bar.Intermittent pushing of the C2 vertebral body in the oropharynx has achieved satisfactory clinical results.However,the preliminary studies included few samples and lacked a control group for comparison. OBJECTIVE:To compare the clinical efficacy of posterior C2-3 fixation combined with the bucking bar technique and posterior C2-3 fixation alone in the treatment of unstable Hangman fractures. METHODS:The clinical and imaging data of 55 patients with unstable Hangman fractures who underwent posterior C2-3 internal fixation in Affiliated Hospital of Southwest Medical University were retrospectively analyzed.According to the surgical plan,the patients were divided into two groups.Among them,23 patients received posterior cervical C2-3 internal fixation combined with the bucking bar technique(group A),and 32 patients received simple posterior C2-3 internal fixation(group B).Operation time,intraoperative blood loss,complications,pain visual analog scale score,neck disability index,American Spinal Injury Association classification,and patient satisfaction(Odom's classification)preoperation and during follow-up were compared between the two groups.The changes in C2-3 displacement and angulation and other imaging indicators were compared at each observation time point. RESULTS AND CONCLUSION:(1)There was no statistically significant difference in operation time,intraoperative blood loss,and postoperative complications between the two groups(P>0.05).(2)The neck pain visual analog scale and neck disability index scores of the two groups of patients at the final follow-up were significantly improved compared with those before surgery(P<0.05).The Odom standard classification showed that 21 cases(91%)in group A were excellent and 29 cases(91%)were excellent and good in group B.There was no statistically significant difference in the clinical efficacy indicators between the two groups(all P>0.05).(3)There was no significant difference in C2-3 angulation and displacement between the two groups before operation(P>0.05).Postoperation and at the last follow-up,the angle and displacement of C2-3 in both groups were significantly smaller than before surgery,and the difference was statistically significant(P<0.01).There was no statistically significant difference in the above indicators after surgery and at the last follow-up(P>0.05).After surgery and at the last follow-up,the displacement and angle of C2-3 in group A were significantly smaller than those in group B(P<0.05).(4)At the last follow-up,no patients in group A had residual deformity,and 4 cases(13%,4/32)in group B had residual deformity.(5)Therefore,posterior C2-3 fixation combined with transoral bucking bar technology may be beneficial to the reduction and stabilization of the vertebral body,reduces malunion,and can achieve better reduction.

Objective To compare the effect of different intensity of neuromuscular training(NMT)on muscle strength and knee joint function of patients after anterior cruciate ligament reconstruction(ACLR).Methods From January,2023 to January,2024,60 ACLR patients in Changhai Hospital were selected,and they received the same intensity of NMT from one to eight weeks after surgery.Eight weeks after surgery,they were randomly divided into low intensity group(n=30)and high intensity group(n=30),and then they received different inten-sities of NMT from nine to 16 weeks after surgery,each training session lasted one hour,with three sessions per week,totaly 48 sessions.The Lysholm score,knee flexor and extensor muscle strength and muscle endurance-were compared at eight weeks and 16 weeks after surgery.Results After group training,the Lysholm score significantly increased in both groups(|t|>13.739,P<0.001),and was higher in the high intensity group than in the low intensity group(t=-2.574,P<0.05);in the high intensity group,the relative peak torque and endurance of the extensor and flexor muscles improved at angular velocities of 60°/s,120°/s and 180 °/s(|t|>2.320,P<0.05);in the low intensity group,the flexor peak torque improved at all the three angular velocities(t>2.177,P<0.05),the extensor peak torque improved at angular velocities of 60°/s and 180°/s(|t|>1.715,P<0.05),and the extensor endurance improved at angular velocity of 60°/s(t=-2.293,P<0.05).However,there was no significant difference in the relative peak torque and endurance of the extensor and flexor muscles at all the three angular velocities(P>0.05).Conclusion Both high and low intensity NMT could improve the muscle strength,muscle endurance and knee joint func-tion.Maybe,high intensity is superior to low intensity.Further verification is still needed.

Aim To explore the mechanism of the co-lonic mucosa of rats with irritable bowel syndrome(IBS)by regulating the Tongxie Yaofang on mecha-nism of short chain fatty acids(SCFAs)and 5-hydroxytryptamine(5-HT)conversion metabolism.Methods The IBS model rats were established by colorectal stimulating baby rats combined with tempora-ry separation of baby rats and female rats.The IBS rats were divided into low-dose Tongxie Yaofang group,high-dose group,model control group,and normal control group.Transmission electron microscopy was used to observe the ultrastructure of the intestinal mu-cosa;ELISA was used to detect the levels of DAO,D-LA,ET,5-HT and 5-HTP in serum;gas chromatogra-phy was used to detect the levels of SCFAs(acetic,propionic and butyric acids)in feces;immunohisto-chemistry was used to detect the expression levels of TPH1,TRPA,5-HTP,5-HT,TGR5,TLR2,5-HT4R and SERT;Western blot was used to detect the expres-sion of intestinal mucosal tight junction proteins Clau-din-1,ZO-1 and Hcy,and the expressions of TPH1,TRPA,TGR5,TLR2 and SERT in colon tissues were further validated.Results Tongxie Yaofang signifi-cantly increased the protein expression of Claudin-1 and ZO-1 of IBS model rats(P＜0.01),decreased Hcy protein expression(P＜0.01),and reduced lev-els of DAO,D-LA,ET,5-HT and 5-HTP in serum(P＜0.05,P＜0.01).It reduced acetic acid,propionic acid and butyric acid content in feces(P＜0.05,P＜0.01),decreased colonic tissue TPH1,TRPA,5-HTP,5-HT,TGR5,TLR2,5-HT4R expression(P＜0.05,P＜0.01),and increased SERT expression(P＜0.05,P＜0.01).Conclusion Tongxie Yaofang improves the pathology of IBS by promoting the expres-sion of intestinal tight junction proteins,regulating the expression of related proteins in the SCFAs-5-HT trans-lational metabolic system,and repairing the intestinal mucosal barrier function.

Recent studies have shown that the physiological homeostasis of oral mucosal cells is regulated by the circadian clock.Dis-ruption or dysfunction of the circadian clock is closely associated with the development of oral squamous cell carcinoma(OSCC).Research based on the circadian clock offers a novel perspective on the pathogenesis and therapeutic strategies for OSCC.However,there is current-ly limited research on this topic,and people generally have insufficient understanding and recognition of the circadian clock.Given the complexity and challenges of circadian clock which is the fourth dimension of medical research,we organize relevant experts based on summarizing the current research results of circadian clock in the pathogenesis and precision diagnosis and treatment of OSCC,combining the scientific principles of the circadian clock's role and their long-term research experience,then summarizes and recommends the con-sensus opinions for the research of circadian clock in the pathogenesis mechanism and precision diagnosis and treatment of human OSCC,with the hope of providing guidance for the basic research and clinical application of circadian clock or circadian rhythm in the pathogene-sis mechanism and precision diagnosis and treatment of oral and maxillofacial squamous cell carcinoma.

Aim To explore the protective effect of icariin on the damage of tight junctional function of Sertoli cells in naturally aging mice and the related mechanism.Methods 15-month-old C57BL/6J male mice were randomly divided into three groups:aging model group,low-dose and high-dose icariin treatment group(5 and 20 mg·kg-1).Another 1-month-old C57BL/6J male mice were considered as adult control group(n=10).The mice in adult control group and aging model group were given the vehicle(0.5％sodi-um carboxymethyl cellulose solution)by intragastric administration,while the mice in icariin-treated groups were given different concentrations of icariin,respec-tively.After continuous administration of icariin for three months,the testes and epididymis were immedi-ately removed,weighed,and the organ index was calcu-lated.Sperm viability and sperm concentration in epi-didymis were measured.The morphological changes of testes were observed by HE staining.The ultrastructur-al changes of tight junctions of Sertoli cells were ob-served by transmission electron microscopy.The ex-pression levels of tight junction-related proteins ZO-1,Occludin,and Claudin11 of testicular Sertoli cells were detected by Western blot.The expression and localiza-tion of ZO-1,Occludin,Raptor,Rictor,p-70S6K,and p-rps6 were detected by immunofluorescence.Results Compared with the aging model group,icariin signifi-cantly increased testicular weight and its index,and ep-ididymal index,improved sperm viability and increased sperm concentration in naturally aging mice.In addi-tion,icariin improved the degeneration of testicular morphology and the damage of ultrastructure of Sertoli cell tight junction with aging.Furthermore,Western blot results showed that icariin up-regulated the expres-sion of ZO-1 and Occludin,but had no significant effect on the expression of Claudin 11.Immunofluorescence assay showed that icariin up-regulated the expression of Rictor,and down-regulated the expression of p-70S6K,p-rps6 and Raptor.Conclusions Icariin improves the tight junction damage of Sertoli cells in naturally aging mice,and its mechanism may be related to restoring the balance between mTORC1 and mTORC2.

Objective To explore the changes of durability properties of reusable surgical gowns when used in dry and wet conditions.Methods Reusable surgical gowns made of single-layer polyester fiber or 3-layer composite material were selected as test samples,and a Martindale abrasion and pilling tester was used as the basic test platform and modified to form fixtures suitable for the wet state environment.The reusable surgical gowns underwent abrasion experiments in wet and dry conditions to observe the changes in their fiber structure,and were subjected to water penetration resistance and swelling strength tests.Results Visually the reusable surgical gowns had few changes of the microscopic textile fiber structure in dry and wet conditions,and the gowns made of single-layer polyster fiber gained advantages over the outer layers of those of 3-layer composite material in abrasion resistance with the same friction cycles.In dry and wet conditions,the hydrostatic pressure values of the gowns of single-layer polyster fiber gradually decreased with the increase of the degree of abrasion,which were always lower than those of the gowns of 3-layer composite material;the swelling strength of the gowns of single-layer polyster fiber was always greater than that of the gowns of 3-layer composite material,which decreased with the deterioration of the wear more significantly than that of the gowns of 3-layer composite material.Conclusion The reusable surgical gowns made of single-layer polyester fiber or 3-layer composite material have few differences in durability and protective properties at the early stages of ablation in dry and wet conditions.The durability of the gowns decreases as the degree of wear increases,while the trend of the decrease is slowing down until the fabric breaks down and completely loses its barrier effect.[Chinese Medical Equipment Journal,2025,46(6):28-33]

Oropharyngeal squamous cell carcinoma(OPSCC)is a malignant tumor originating from the squamous epithelium of the oro-pharyngeal mucosa,accounting for more than 90％of oropharyngeal malignancies.In recent years,human papillomavirus(HPV)infec-tion has become one of the primary etiological factors of oropharyngeal squamous carcinoma.The incidence of HPV-associated oropharyn-geal squamous carcinoma has been rising annually,with a noticeable trend toward younger populations,posing a significant threat to hu-man health.Due to the distinct biological behavior and clinical characteristics of HPV-associated oropharyngeal squamous carcinoma com-pared to its non-HPV-related counterpart,the diagnostic and treatment strategies for oropharyngeal squamous carcinoma have undergone substantial changes.Prevention and screening for oropharyngeal squamous carcinoma are of critical importance.The diagnostic and treat-ment process involves multi-disciplinary collaboration,including oral and maxillofacial surgery,otolaryngology,head and neck surgery,oncology,radiology and pathology.Based on evidence from clinical practice,a comprehensive,integrated diagnostic and therapeutic ap-proach has been established,centered around the concept of"prevention,screening,diagnosis,treatment,and rehabilitation",covering the entire patient lifecycle and providing a valuable reference for clinical practice.

Objective To construct a support system that facilitates the participation of children with special needs(CSN)in physi-cal activity within the context of inclusive education.Methods Based on World Health Organization(WHO)health promoting school(HPS)framework,and integrating WHO International Classification of Functioning,Disability and Health(ICF)as well as the WHO guidelines on physi-cal activity,a systematic and multidimensional support framework was developed.Results In the context of inclusive education,the primary forms of physical activity for CSN included physical educa-tion classes and extracurricular sports activities.A comprehensive support system was developed at macro-,me-so-and micro-levels.At the macro-level,the framework called for the establishment of inclusive physical educa-tion and activity-related policies,accessible and universally designed physical environments,inclusive activity climates,and integrated community resources.At the meso-level,it emphasized creating a supportive profession-al development environment for inclusive physical education teachers,equipping them with skills in inclusive pedagogy,classroom management and extracurricular activity planning.At the micro-level,it focused on the de-sign of physical education curricula tailored to the physical activity and motor development needs of CSN,the es-tablishment of individualized learning support mechanisms,and encouraging active participation in physical edu-cation and physical activities.Conclusion To address the physical activity and educational needs of CSN in inclusive education settings,a three-tiered support system has been constructed.The macro-level involves policy,environment and community;the meso-level focuses on teachers and instructional practices;and the micro-level targets students'learning,motor devel-opment and health.

Aim To investigate the effects of m6A demethylase ALKBH5 on cardiomyocytes pyroptosis in mice with myocardial infarction(MI).Methods The MI model of left anterior descending coronary artery ligation surgery was established by knocking down ALKBH5 using adeno-associated virus,and the hypox-ia model of mouse cardiomyocytes(HL-1)was estab-lished by knocking down small interfering RNA.The effects of ALKBH5 on the pyroptosis of MI mice and hypoxic HL-1 cells were observed.Subsequently,mechanism studies were conducted at the cellular lev-el,and the binding of ALKBH5 and IGF2BP2 to NL-RP3 mRNA was detected through RNA pull down and RNA immunoprecipitation(RIP)experiments.The MeRIP-qPCR method was used to determine the effects of ALKBH5 on the mRNA m6A level of NLRP3.Acti-nomycin D for RNA stability experiments were conduc-ted to detect the effects of ALKBH5 and IGF2BP2 on the stability of NLRP3 mRNA.Results Knocking down ALKBH5 in vivo and in vitro both inhibited NL-RP3 inflammasome activation and alleviated pyroptosis in MI mice and hypoxic HL-1 cells.Mechanistically,the results showed that NLRP3 mRNA could bind to ALKBH5 protein in HL-1 cells;knocking down ALK-BH5 could increase the m6A level of NLRP3 and re-duce the stability of NLRP3 mRNA;subsequently,it was confirmed that NLRP3 mRNA and IGF2BP2 pro-tein bound to each other;knocking down IGF2BP2 in-creased the mRNA stability of NLRP3.The Rescue ex-periment showed that knocking down IGF2BP2 re-versed the decrease in NLRP3 mRNA expression caused by knocking down ALKBH5.Conclusions ALKBH5 mediated m6A modification of NLRP3 pro-motes cardiomyocytes pyroptosis in mice with myocardi-al infarction.
