Objective:To compare the outcomes of multiple scales, primarily the speech, spatial, and other qualities of hearing scale for parents（SSQ-P）, in children with ipsilateral vs. Contralateral cochleareimplantat ion（CRI）. Methods: A total of 69 children who received cochlear implantation surgery from April 1999 to June 2024 were included. Patients were divided into two groups based on whether the implantation was on the same side. General information such as gender, age, age at initial implantation and reimplantation was collected. The primary caregivers of the children were followed up by telephone using the categories of auditory performance（CAP）, speech intelligibility rating（SIR）, and SSQ-P questionnaires. Statistical methods including stepwise regression, linear regression, and permutation tests were employed to investigate if there were any statistically significant differences in the scores of CAP, SIR, SSQ-P total, SSQ-P speech perception, SSQ-P spatial hearing, and SSQ-P auditory quality dimensions between the ipsilateral and contralateral reimplantation groups. Results:Of the 69 children included, 62 were in the ipsilateral reimplantation group with a mean age of 11.1 years, and 7 were in the contralateral reimplantation group with a mean age of 11.7 years. Statistical analysis showed that patients in the contralateral reimplantation group had significantly lower SSQ-P total scores （P<0.05） and spatial hearing dimension scores （P<0.05） than those in the ipsilateral reimplantation group after controlling for the corresponding confounders. Conclusion:The effect of ipsilateral reimplantation of cochlear implants is superior to that of contralateral reimplantation in terms of overall auditory function and spatial hearing in daily life for children, but the mechanisms require further investigation.

After being treated with acupuncture, some patients with idiopathic tinnitus may experience a short-term aggravation of tinnitus symptoms on the original basis. These symptoms can be gradually relieved and the overall condition fluctuates towards recovery. This phenomenon has brought some difficulties to patients and clinicians. Based on the academic view of TCM, "destroying pathogens and re-building balance", and in association with the existing understanding of acupuncture in modern medicine for tinnitus, this paper briefly discusses the mechanism and influencing factors of symptom fluctuation in patients with idiopathic tinnitus after acupuncture treatment in terms of both TCM and modern medicine, and proposes the future direction in the research of symptom fluctuation, so as to promote the recognition of clinicians and patients on symptom fluctuation and make rational use of its positive effects. Besides, it is hoped that more researchers will pay attention to symptom fluctuation and advance the exploration of it in academic field.

This review summarizes the applications and advancements of artificial intelligence(AI)in the analysis of retinal vascular parameters. Retinal vascular parameters, including vessel diameter, fractal dimension, vascular tortuosity, branching angles, and vessel density, are important indicators for assessing changes in the retinal vascular network structure. These parameters are not only related to various ophthalmic diseases but also reflect the conditions of systemic diseases such as diabetes and Alzheimer's disease. This article provides a detailed discussion on the advantages of AI technology in the automated identification and quantification of retinal vascular parameters, particularly in improving measurement efficiency and accuracy, and enabling the early detection and monitoring of various diseases. Additionally, the challenges faced by AI in the analysis of retinal vascular parameters were discussed, such as data standardization and insufficient sample diversity, and proposes directions for future research. By thoroughly analyzing the application of AI in retinal vascular parameter analysis, this article aims to offer new perspectives and methods for clinical diagnosis and early intervention of diseases, holding significant clinical significance and application prospects.

Objective:To investigate the risk factors for the formation of eggshell vertebral body after open reduction and internal fixation with posterior screw-rod system for thoracolumbar spine fractures. Methods:A retrospective study was conducted to analyze the 118 patients with thoracolumbar single-segment fracture who had been treated at Department of Orthopaedic Surgery, The First Hospital Affiliated to Soochow University between January 2020 and January 2023. The patients were divided into a case group (47 cases) and a control group (71 cases) according to whether an eggshell vertebral body developed in the injured vertebra after internal fixation with posterior screw-rod system. The 2 groups were compared in terms of gender, age, follow-up time, body mass index, history of primary hypertension, history of diabetes mellitus, vertebral bone quality (VBQ) score, local Cobb angle correction, presence or absence of screwing at the injured vertebra, fracture site, fracture type, presence or absence of injury to the posterior ligamentous complex, presence or absence of injury to the upper and lower discs/endplate complex in the injured vertebrae, recovery rates of the anterior, middle, and posterior heights of the injured vertebra, and preoperative and postoperative visual analog scale (VAS) for pain. After positive indicators were screened by univariate analysis ( P<0.05), they were included in a multivariate logistic regression model and receiver operating characteristic curve (ROC) to analyze the risk factors for the formation of eggshell vertebral body after posterior screw-rod internal fixation of thoracolumbar spine fractures. Results:Of the 118 patients, 47 developed an eggshell vertebral body after surgery. Univariate analysis showed that VBQ score, presence or absence of screwing at the injured vertebra, burst fracture type, injury to the posterior ligamentous complex, injury to the upper and lower discs/endplate complex in the injured vertebrae, recovery rate of the anterior height of the injured vertebra, recovery rate of the middle height of the injured vertebra were statistically significant ( P<0.05). The multivariate logistic regression analysis and ROC curve analysis showed that a VBQ score ≥ 2.95 points( OR=6.216, 95% CI: 1.890 to 20.441, P=0.003), a recovery rate of the anterior height of the injured vertebra ≥ 25.26% ( OR=1.097, 95% CI: 1.046 to 1.149, P<0.001), a burst fracture type ( OR=6.397, 95% CI: 1.733 to 23.617, P=0.005), and injury to the upper and lower discs/endplate complex in the injured vertebrae ( OR=7.581, 95% CI: 1.827 to 31.461, P=0.005) were significantly associated with the formation of eggshell vertebral body after open reduction and internal fixation with posterior screw-rod system for thoracolumbar spine fractures ( P<0.05). Conclusion:A VBQ score ≥ 2.95 points, a recovery rate of the anterior height of the injured vertebra ≥ 25.26%, a burst fracture type, and injury to the disc/endplate complex in the injured vertebrae are the independent risk factors for the formation of eggshell vertebral body after open reduction and internal fixation with posterior screw-rod system for thoracolumbar spine fractures.

Objective:To investigate the impact of preoperative sarcopenia on chronic postsurgical pain(CPSP)after cardiac surgery in elderly patients.Methods:Elderly patients undergoing elective open-chest cardiac surgery at the Affiliated Hospital of Xuzhou Medical University from September 2022 to May 2024 were collected.According to the updated diagnostic criteria and revised by the Asian Working Group for Sarcopenia(AWGS2019)in 2019, patients were classified into sarcopenia and non-sarcopenia groups Elderly patients were divided into two groups based on the occurrence of chronic pain at 3 months postoperatively: CPSP group and non-CPSP group.Indicators with statistically significant differences in univariate regression analysis were included in multifactorial regression to analyze the influencing factors of chronic pain after cardiac surgery in elderly patients.The receiver operating characteristic(ROC)curve was plotted and the area under the curve(AUC)was calculated to compare the predictive efficacy of sarcopenia, commonly used clinical pain assessment tools(gender+ acute postoperative pain), and(gender+ acute postoperative pain+ sarcopenia)in predicting CPSP after cardiac surgery in elderly patients.Results:The study ultimately included 379 patients, consisting of 238 males(62.8%), with an average age of(66.6 ± 5.3)years.Among them, 83 patients had sarcopenia, and 119 patients developed CPSP.Univariate regression analysis showed that gender, history of atrial fibrillation, acute postoperative pain, American Society of Anesthesiologists(ASA)Physical Status Classification System, New York Heart Association(NYHA)Classification of Cardia Function, sarcopenia, and duration of extracorporeal circulation were associated with the occurrence of CPSP after cardiac surgery in elderly patients.However, after adjusting for all possible confounders, multifactorial regression analysis showed that gender, acute postoperative pain, and sarcopenia were independent risk factors for CPSP after cardiac surgery in elderly patients(all P<0.05), with sarcopenia patients having a 2.913-fold risk of developing CPSP compared with non-sarcopenia patients.The AUCs of the ROC curves for commonly used clinical perioperative pain assessment tools and those with the addition of sarcopenia determination were 0.731 and 0.802, respectively. Conclusions:Preoperative sarcopenia is an independent risk factor for the development of chronic pain after cardiac surgery in elderly patients, and the inclusion of sarcopenia determination in commonly used clinical pain assessment tools can significantly improve the predictive efficacy for chronic pain.

To explore the application of sequential analysis in post-market safety dynamic surveillance of vaccines. Under the dynamic monitoring data of vaccines post-market approval, this research introduces the fundamental principles of maximizing sequential probability ratio test (MaxSPRT) and Bayesian sequential analysis, employing R software. Through an example of dynamic safety monitoring data of vaccines post-market approval, we analyze using the MaxSPRT and Bayesian sequential analysis. The MaxSPRT identified a safety signal in week 4 ( P<0.05), while Bayesian sequential analysis indicated that the 95% highest density interval for the RR value at week 4 is 1.13-3.27, suggesting the first appearance of a safety signal at week 4. The MaxSPRT and Bayesian sequential analysis effectively leverage continuously accumulating dynamic monitoring data, thereby serving as a valuable method for post-market safety surveillance of vaccines.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

OBJECTIVES: To explore the mechanism by which Pulsatilla saponin D (PSD) inhibits invasion and metastasis of triple-negative breast cancer (TNBC). METHODS: The public databases were used to identify the potential targets of PSD and the invasion and metastasis targets of TNBC to obtain the intersection targets between PSD and TNBC. The "PSD-target-disease" interaction network was constructed and protein-protein interaction (PPI) analysis was performed to obtain the core targets, which were analyzed for KEGG pathway and GO functional enrichment. Molecular docking study of the core targets and PSD was performed, and the therapeutic effect and mechanism of PSD were verified using Transwell assay and Western blotting in cultured TNBC cells. RESULTS: Network pharmacology analysis identified a total of 285 potential PSD targets and 26 drug-disease intersection core targets. GO analysis yielded 175 entries related to the binding of biomolecules (protein, DNA and RNA), enzyme activities, and regulation of gene transcription. KEGG analysis yielded 46 entries involving pathways in cancer, chemical carcinogenesis-receptor activation, microRNAs in cancer, chemical carcinogenesis-reactive oxygen species, PD-L1 expression and PD-1 checkpoint pathway in cancer. Molecular docking showed high binding affinities of PSD to MTOR, HDAC2, ABL1, CDK1, TLR4, TERT, PIK3R1, NFE2L2 and PTPN1. In cultured TNBC cells, treatment with PSD significantly inhibited cell invasion and migration and lowered the expressions of MMP2, MMP9, N-cadherin and the core proteins p-mTOR, ABL1, TERT, PTPN1, HDAC2, PIK3R1, CDK1, TLR4 as well as NFE2L2 expressionin the cell nuclei. CONCLUSIONS The inhibitory effects of PSD on TNBC invasion and metastasis are mediated by multiple targets and pathways.
