To evaluate long-term survival and clinical outcomes of patients with knee osteo-arthritis undergoing total knee arthroplasty (TKA) through long-term follow-up. This study was based on a previous cohort study that had completed follow-up. We retrospectively collected clinical data of patients with knee arthropathy (including knee osteoarthritis and knee rheumatoid arthritis) who received the first TKA operation in Peking Union Medical College Hospital from 1993 to 2002 and were followed up for more than 20 years, and conducted a unified follow-up on them in November 10, 2024 (the last follow-up). Kaplan-Meier curve was used to evaluate the survival rate. Hospitals for special surgery (HSS) scores and joint range of motion (ROM) were compared before surgery, 10 years after surgery and at the last follow-up to evaluate the clinical efficacy of TKA. Likert scale was used to evaluate patient satisfaction at the last follow-up. A total of 226 patients (246 knees) received their first TKA in Peking Union Medical College Hospital from 1993 to 2002 and were followed up for more than 10 years. Among them, 104 patients (131 knees) were included in the study at the last follow-up, including 21 patients (24 knees) with prosthesis in place, 18 patients (18 knees) who underwent reoperation for various reasons, and 65 patients (89 knees) who died from non-TKA surgical causes. Up to the last follow-up, there were 29 patients (35 knees) with an average follow-up of more than 20 years, and 12 patients (16 knees) completed HSS score, ROM measurement and patient satisfaction evaluation. Kaplan-Meier curve showed that the 10-year, 15-year, 20-year, and 25-year survival rates were 93.6%, 92.4%, 89.8%, and 71.8%, respectively. The HSS score at the last follow-up was lower than that at 10- year postoperative follow-up[(84.69±11.03) scores TKA treatment for knee arthropathy has high long-term prosthesis survival rate, significant improvement of knee joint function and high patient satisfaction.

To analyze the occurrence of early complications after total hip arthroplasty (THA) in patients with systemic lupus erythematosus (SLE). The data of patients who underwent THA at Peking Union Medical College Hospital from June 2012 to April 2024 were retrospectively and consecutively collected. The patients were categorized into SLE group and control group based on the presence or absence of SLE. Using propensity score matching, we matched patients in the two groups at a 1∶1 ratio according to gender, age, and surgical side. Subsequently, we compared the clinical characteristics, incidence of major complications within 30 days postoperatively, and allogeneic blood transfusion rates between the two groups. A total of 270 patients in the SLE group who met the inclusion and exclusion criteria were selected. Within 30 days postoperatively, 18 cases (6.67%) experienced major complications, including 2 cases (0.74%) of upper respiratory tract infection, 2 cases (0.74%) of pulmonary infection, 3 cases (1.11%) of urinary tract infection, 2 cases (0.74%) of other systemic infection, 5 cases (1.85%) of poor wound healing, 1 case (0.37%) of wound infection, 1 case (0.37%) of gastrointestinal complications, 1 cases (0.37%) of shock, and 1 case (0.37%) of SLE flare-up. The allogeneic blood transfusion rate was 22.59% (61/270). After propensity score matching, 163 cases from SLE and control groups were included for analysis. (1) Regarding medical complications, compared with control group, SLE group showed significant differences in osteoporosis, respiratory system disorders, gastrointestinal diseases, urinary system disorders, hematologic abnormalities, and secondary or concomitant rheumatic diseases (all The incidence of major complications within 30 days following THA in patients with SLE was significantly higher than that in non-SLE patients, while the rate of allogeneic blood transfusion remained comparable. To ensure the safety of THA surgery for patients with SLE, it is important to optimize the patient's condition and achieve stabilization prior to surgery. Additionally, strict perioperative management must be forced.

Traditional Chinese medicine (TCM) represents a paradigmatic approach to personalized medicine, developed through the systematic accumulation and refinement of clinical empirical data over more than 2000 years, and now encompasses large-scale electronic medical records (EMR) and experimental molecular data. Artificial intelligence (AI) has demonstrated its utility in medicine through the development of various expert systems (e.g., MYCIN) since the 1970s. With the emergence of deep learning and large language models (LLMs), AI's potential in medicine shows considerable promise. Consequently, the integration of AI and TCM from both clinical and scientific perspectives presents a fundamental and promising research direction. This survey provides an insightful overview of TCM AI research, summarizing related research tasks from three perspectives: systems-level biological mechanism elucidation, real-world clinical evidence inference, and personalized clinical decision support. The review highlights representative AI methodologies alongside their applications in both TCM scientific inquiry and clinical practice. To critically assess the current state of the field, this work identifies major challenges and opportunities that constrain the development of robust research capabilities-particularly in the mechanistic understanding of TCM syndromes and herbal formulations, novel drug discovery, and the delivery of high-quality, patient-centered clinical care. The findings underscore that future advancements in AI-driven TCM research will rely on the development of high-quality, large-scale data repositories; the construction of comprehensive and domain-specific knowledge graphs (KGs); deeper insights into the biological mechanisms underpinning clinical efficacy; rigorous causal inference frameworks; and intelligent, personalized decision support systems.

Neuropathic pain is frequently comorbidity with cognitive deficits. Neuralized1 (Neurl1)-mediated ubiquitination of CPEB3 in the hippocampus is critical in learning and memory. However, the role of Neurl1 in the cognitive impairment in neuropathic pain remains elusive. Herein, we found that lumbar 5 spinal nerve ligation (SNL) in male rat-induced neuropathic pain was followed by learning and memory deficits and LTP impairment in the hippocampus. The Neurl1 expression in the hippocampal CA1 was decreased after SNL. And this decrease paralleled the reduction of ubiquitinated-CPEB3 level and reduced production of GluA1 and GluA2. Overexpression of Neurl1 in the CA1 rescued cognitive deficits and LTP impairment, and reversed the reduction of ubiquitinated-CPEB3 level and the decrease of GluA1 and GluA2 production following SNL. Specific knockdown of Neurl1 or CPEB3 in bilateral hippocampal CA1 in naïve rats resulted in cognitive deficits and impairment of synaptic plasticity. The rescued cognitive function and synaptic plasticity by the treatment of overexpression of Neurl1 before SNL were counteracted by the knockdown of CPEB3 in the CA1. Collectively, the above results suggest that the downregulation of Neurl1 through reducing CPEB3 ubiquitination and, in turn, repressing GluA1 and GluA2 production and mediating synaptic plasticity impairment in hippocampal CA1 leads to the genesis of cognitive deficits in neuropathic pain.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objectives:To analyze the long-term prognosis of patients with locally advanced gastric cancer in the stage of ypT0~2N0M0 after neoadjuvant chemotherapy.Methods:The clinical data of 78 patients with locally advanced gastric cancer who underwent neoadjuvant chemotherapy and radical resection at ypT0~2N0M0 stage from January 2012 to December 2019 in the Department of Abdominal Surgery/Pancreatic and Gastric Surgery of the Cancer Hospital of Chinese Academy of Medical Sciences were retrospectively analyzed. Kaplan-Meier method was used to calculate the overall survival and disease-free survival, and the survival difference between patients with postoperative ypT0N0M0 and ypT1~2N0M0 was compared. Multivariate Cox proportional hazards regression analysis was performed on clinical, pathologic and treatment measures that may affect survival.Results:Among the 78 patients, there were 18 cases (23.1%) with ypT0N0M0, 14 cases (17.9%) with ypT1aN0M0, 17 cases (21.8%) with ypT1bN0M0, and 29 cases (37.2%) with ypT2N0M0. Median follow-up time was 74.1 (19.8~132.5) months. Fourteen patients (17.9%) had tumor recurrence and metastasis, and 9 patients died from tumor recurrence and metastasis. The 5-year disease-free survival and overall survival rates were 84.4% and 87.8%, respectively. There was no statistically significant difference in 5-year overall survival (86.9% vs 87.8%) or 5-year disease-free survival (88.9% vs 83.2%) between patients with ypT0N0M0 and ypT1~2N0M0. Analysis of factors that may affect prognosis revealed that signet ring cell carcinoma, nerve invasion, and lymph node dissection of fewer than 16 were significantly associated with prognosis ( P<0.05). Multivariate Cox analysis including these three factors showed that only lymph node dissection of fewer than 16 was an independent risk factor affecting prognosis (OS: HR=10.44 ,95% CI: 2.15-50.72, P=0.004; DFS: HR=11.47, 95% CI: 2.85-46.20, P=0.001). Conclusions:The long-term prognosis of patients with locally advanced gastric cancer at ypT0~2N0M0 stage after neoadjuvant chemotherapy is relatively good, and the long-term survival time of patients with ypT1~2N0M0 and ypT0N0M0 is similar. Lymph node dissection of less than 16 nodes may be an independent risk factor affecting prognosis. During surgery, efforts should be made to increase the number of lymph node dissections. For patients with less than 16 nodes dissected, postoperative treatment and follow-up should be strengthened.

This article summarizes and organizes relevant publications in journals, along with a review of medical history, systematically summarizing the development process of dental alveolar surgery in China. The initial establishment phase (1935—1952) marked the starting point of Chinese Alveolar Surgery. Despite the impact of wars, it laid the foundation for subsequent research and practice. During the early development phase (1953—1966), the "Chinese Journal of Stomatology" was founded, which promoted the development of Alveolar Surgery. Research focused on tooth extraction methods and complications. Tooth Transplantation and Preprosthetic Surgery gradually began to take off. The stagnant phase (1967—1977) occurred due to the interruption of international exchanges, leading to an almost complete halt in the development of Alveolar Surgery. Entering the rapid catch-up phase (1978—1985), Alveolar Surgery scholars in China began striving to overcome the stagnation of the previous decade. While some progress was made, no significant innovative achievements emerged. In the scientific development phase (1986—2010), clinical research, basic experiments, and paper writing in modern Chinese Alveolar Surgery began to adhere to scientific standards with the rise of experimental medicine. The exploration and innovation stage (2011—2023) is the current development phase, during which Chinese Aveolar Surgery has reached its peak, making substantial progress in technology, clinical practices, and basic research, gradually reaching or even surpassing international advanced levels. Looking back at the development history in China, we can find the wisdom and hard work of the older generation of Alveolar Surgery scholars. However, contemporary challenges and issues, such as standardizing technology, promoting clinical practices, and talent cultivation, need to be addressed by present-day Alveolar Surgery professionals as they forge ahead.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
