ObjectiveTo detect the proportion of splenic follicular helper T （Tfh） cells and their functionally related cytokine expression levels in the incomplete embryo implantation disorder （EID） model mice， and to explore the immunological mechanism of Tfh in infertility caused by embryo implantation disorder. MethodsSixteen female Kunming mice were randomly divided into two groups， with eight mice in each group. On day 4 of pregnancy， an incomplete EID mouse model was established by oral gavage of mifepristone suspension， while an equal volume of saline was administered to the control group. On day 8 of pregnancy， the mice were euthanized. Flow cytometry was used to detect the levels of Tfh cells in the spleen lymphocytes of both incomplete EID mice and normal control mice. qRT-PCR was performed to measure the mRNA levels of B-cell lymphoma 6 （Bcl-6） and C-X-C chemokine receptor type 5 protein （CXCR5） in the spleen lymphocytes of both groups. Western blot was employed to assess the protein expression levels of Bcl-6 and CXCR5 in the spleen lymphocytes of both groups. Serum levels of interleukin-4 （IL-4）， IL-6， and IL-21 were measured by ELISA. Immunohistochemistry （IHC） was used to observe the expression levels of progesterone receptor （PR）， Bcl-6， and CXCR5 proteins in the uterine endometrial tissue of mice in both groups. ResultsIncomplete-type EID mice had a reduced number of embryo implantation points and reduced endometrial PR expression. Flow assay results showed that the proportion of CD4⁺CXCR5⁺Tfh cells in splenic lymphocytes of incomplete-type EID mice was significantly higher than that of normal controls （P<0.05）. Compared with the normal control group， Bcl-6 and CXCR5 mRNA levels and protein levels were elevated in splenic lymphocytes of incomplete EID mice， with statistically significant differences （P<0.05）； serum IL-4， IL-6， and IL-21 levels were elevated in incomplete EID mice， and Bcl-6 and CXCR5 proteins in the endometrium were significantly elevated （P<0.05）. ConclusionThe increase of Tfh cells and their associated cytokines Bcl-6 and CXCR5 is associated with the development of incomplete EID， and may be involved in the development of female immune infertility.

OBJECTIVE: To evaluate the effectiveness of the single-stage anterior eccentric kyphotic distraction reduction technique (EKD-RT) for treating lower cervical dislocation with locked facet joints, assessing its reduction success rate, neurological improvement, and safety. METHODS: A retrospective analysis was conducted on 67 patients with lower cervical dislocation and locked facet joints (21 unilateral, 46 bilateral) treated between January 2015 and January 2024. There were 39 males and 28 females, with an average age of 49.5 years (range, 22-75 years). The injured segments included C _{3, 4} in 4 cases, C _{4, 5} in 13 cases, C _{5, 6} in 22 cases, and C _{6, 7} in 28 cases. The interval between injury and admission ranged from 2 hours to 2 days (mean, 5.6 hours). Preoperative Frankel grading included grade A in 9 cases, grade B in 28 cases, grade C in 17 cases, grade D in 11 cases, and grade E in 2 cases. Japanese Orthopaedic Association (JOA) score was 7.0±1.4. All patients underwent single-stage anterior cervical discectomy and fusion. Following discectomy at the dislocated level, the EKD-RT was applied to unlock and reduce the locked facet joints, followed by internal fixation. Operation time, blood loss, reduction success rate, and complications were recorded. Interbody fusion status was evaluated using Bridwell criteria. Neurological status was assessed pre- and post-operatively using Frankel grading. Spinal cord function was scored using the 17-point JOA score, and the improvement rate was calculated. RESULTS: Successful reduction of the locked facet joints achieved in all cases. The operation time was 41-85 minutes (range, 63.3 minutes), and intraoperative blood loss was 50-360 mL (range, 125.0 mL). Complications included cerebrospinal fluid leakage in 2 cases; no severe complications such as major vascular injury or recurrent laryngeal nerve injury occurred. All patients were followed up 12-24 months (mean, 17.9 months). At last follow-up, radiological examination confirmed interbody fusion in all patients, with no implant failure or migration. The Frankel grading included grade A in 3 cases, grade B in 9 cases, grade C in 13 cases, grade D in 16 cases, and grade E in 26 cases; the JOA score reached 13.7±2.3; all of which significantly improved compared to preoperative levels ( P<0.05). The improvement rate of JOA score was 66.1%±24.7%. CONCLUSION The EKD-RT is an effective surgical approach for lower cervical dislocation with locked facet joints. It enables safe and efficient reduction of the locked facet joints via a single incision, resulting in significant neurological improvement with a low complication rate.

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.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis. However, it still lacks effective predictors and approaches. Here, a classical model of pharmacoresistant temporal lobe epilepsy (TLE) was established to screen pharmacoresistant and pharmaco-responsive individuals by applying phenytoin to amygdaloid-kindled rats. Ictal electroencephalograms (EEGs) recorded before phenytoin treatment were analyzed. Based on ictal EEGs from pharmacoresistant and pharmaco-responsive rats, a convolutional neural network predictive model was constructed to predict pharmacoresistance, and achieved 78% prediction accuracy. We further found the ictal EEGs from pharmacoresistant rats have a lower gamma-band power, which was verified in seizure EEGs from pharmacoresistant TLE patients. Prospectively, therapies targeting the subiculum in those predicted as "pharmacoresistant" individual rats significantly reduced the subsequent occurrence of pharmacoresistance. These results demonstrate a new methodology to predict whether TLE individuals become resistant to ASMs in a classic pharmacoresistant TLE model. This may be of translational importance for the precise management of pharmacoresistant TLE.

OBJECTIVE To understand the healthcare-seeking behavior of patients with AIDS co-infected with tu-berculosis and analyze the factors influencing delayed consultation and diagnosis,and to provide a theoretical basis for the implementation of interventional tuberculosis control measures.METHODS Two hundred and two patients with AIDS complicated with tuberculosis who were first admitted to Yunnan Infectious Diseases Hospital from Jan.2020 to Dec.2023 were selected,and their clinical data were collected through the inpatient medical record system.Multivariate logistic regression model was used to analyze the factors influencing delayed consultation and diagnosis.RESULTS Time of admission,place of residence,presence of lung cavities,distribution of lung lesions,intermediate hospital visited,sputum culture results,etiological situation,CD4+/CD8+cell ratio,and CD8+cell counts were the factors influencing delayed consultation(P<0.05).The initial diagnosis and Gene-Xpert results were the factors influencing delayed diagnosis(P<0.05).Multivariate logistic regression analysis showed that ad-mission in 2021(OR=3.842,95%CI:1.651-8.966),and presence of lung cavity(OR=8.007,95%CI:1.381-6.436),single lung lesion accumulation(OR=0.637,95%CI:0.049-8.267)were risk factors for delayed consultation.A 10%reduction in body mass(OR=2.070,95%CI:1.056-4.059)and negative Gene-Xpert re-sults(OR=1.667,95%CI:0.688-4.038)were risk factors for delayed diagnosis.CONCLUSIONS The issues of delayed medical consultation and diagnosis in patients with AIDS complicated with tuberculosis remain severe,with different factors influencing the delay.Special attention should be paid to the screening for latent tuberculosis infection in people infected with HIV.When experiencing suspicious symptoms,patients should go be encouraged to take exams at designated tuberculosis hospitals,repeatedly collect sputum samples and monitor changes in body mass,all of which are positively significant in reducing delays.

[Purpose]To analyze the trends of incidence and mortality of lung cancer in Jinshan District of Shanghai from 2002 to 2020.[Methods]The data of lung cancer was obtained from the Shanghai Cancer Registry and the population data was obtained from the Jinshan District Bureau of Public Security.The crude rate and age-standardized rate of incidence and mortality(ASIR and ASMR),and the average annual percentage change(AAPC)of lung cancer were calculated.[Results]From 2002 to 2020,8 982 new cases and 6 081 deaths of lung cancer were reported.The ASIR of lung cancer increased from 36.55/105 to 56.72/105 with an AAPC of 3.34％(P＜0.05).The ASIR was also increased in male and female,with higher increase in female(AAPC=8.56％)than that in male(AAPC=0.50％).The ASMR decreased from 32.25/105 to 23.06/105 with an AAPC of-2.08％(P＜0.05).The ASMR was decreased both in male and female,with higher decline in male(AAPC=-2.71％)than that in female(AAPC=-0.43％).The disease risk in male was higher than that in female,while the difference in ASIR between male and female was decreasing.The inci-dence and mortality increased with age.[Conclusion]From 2002 to 2020,the incidence of lung cancer in Jinshan District was increasing,but the age-standardized mortality was decreasing.The incidence and mortality of lung cancer varied among different ages and sexes,so targeted preven-tion and control measures should be implemented.

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 observe any therapeutic effect of transcranial direct current stimulation (tDCS) combined with intermittent oroesophageal tube feeding (IOE) on dysphagia among ischemic stroke survivors.Methods:Eighty-four ischemic stroke survivors with dysphagia were randomized into an observation group and a control group, each of 42. In addition to conventional rehabilitation, swallowing training and IOE, the observation group received tDCS while the control group received sham stimulation. Before and after 14 days of this treatment, both groups′ swallowing, life quality and depression were evaluated using the Penetration Aspiration Scale (PAS), the Functional Oral Intake Scale (FOIS), the Dysphagia Handicap Index (DHI), and a 9-item patient health questionnaire (PHQ-9).Results:There were no significant differences between the two groups before the experiment in terms of their general data, their average PAS, FOIS, DHI or PHQ-9 scores, or the incidence of depression. After the treatment, significant improvement was observed in the above indicators among both groups, but with significantly better average PAS, FOIS, DHI [(51.25±6.78) vs. (44.78±5.75)] and PHQ-9 [(4.17±1.15) vs. (6.01±1.93)] scores and less depression (14.29% vs. 42.86%) in the observation group compared with the control group.Conclusions:Combining tDCS with IOE better improves swallowing function, depression, and life quality after an ischemic stroke.
