By analyzing the current application of multi-modal data in the diagnosis of gastric "inflammation-cancer" transformation， this study explored the feasibility and strategies for constructing a disease-syndrome integrated diagnosis and treatment system. Based on traditional Chinese medicine （TCM） phenomics， we proposed utilizing multi-modal data from literature research， cross-sectional studies， and cohort follow-ups， combined with artificial intelligence technology， to establish a multi-dimensional diagnostic and treatment index system. This approach aims to uncover the complex pathogenesis and transformation patterns of gastric "inflammation-cancer" progression. Additionally， by dynamically collecting TCM four-diagnostic information and modern medical diagnostic information through a long-term follow-up system， we developed three major modules including information extraction， multi-modal phenotypic modeling， and information output， to make it enable real-world clinical data-driven long-term follow-up and treatment of chronic atrophic gastritis. This system can provide technical support for clinical diagnosis， treatment evaluation， and research， while also offering insights and methods for intelligent TCM diagnosis.

[Objective] To explore the clinical features of IgG4-related urinary diseases so as to provide reference for the diagnosis and treatment of such diseases. [Methods] The clinical data of 4 cases of IgG4-related urinary system diseases diagnosed and treated in Xijing Hospital of Air Force Medical University during Aug.2019 and Dec.2023 were retrospectively collected.Here, we report on the diagnosis and treatment of these patients, analysing their symptoms, serology, imaging and pathology as well as their treatment and outcomes. [Results] The patients included 2 male and 2 female.The lesions were involved with the retroperitoneum and urinary system.Three patients had symptoms of lumbar pain.The imaging manifestations were complex, including retroperitoneal mass involving urinary system organs in 2 cases, tabdense shadow of the right kidney in 1 case, and simple cystic mass of kidney in 1 case.Serum IgG4 value was not detected before surgery.All patients underwent radical surgical treatment.Postoperative pathology showed fibrous tissue hyperplasia with a large number of plasma cells, lymphocytes, a few neutrophil infiltrates, and lymphoid follicles and obliterated vasculitis in some specimens.The number of IgG4⁺ plasma cells was more than 10 in all tissues under high power microscope.After surgery, 3 patients had symptoms improved, and serum IgG4 value was within the normal range; 1 patient (patem 3) had elevated IgG4 value during follow-up, received subsequent hormone therapy, and the serum IgG 4 level remained stable. [Conclusion] The symptoms of IgG4-related diseases involving the urinary system are non-specific, and the imaging findings are various, easily confused with other diseases.Early detection of serum IgG4 and biopsy pathology can help clinicians make correct diagnosis in the early stage.

People’s health is an essential requirement of Chinese-style modernization. The red doctor spirit serves as the fundamental safeguard for achieving the goal of people’s health. What is the red doctor spirit？ What is the relationship between the red doctor spirit and virtue ethics？ How can virtues shape the red doctor spirit and seek theoretical support for this spirit from extensive and profound ethical resources？ From the perspective of virtue ethics， the red doctor spirit refers to the virtue requirements that the Communist Party of China （CPC） puts forward for medical workers during the process of leading the Chinese people to create and develop healthcare undertakings with Chinese characteristics， including political firmness， respecting life and healing the wounded and rescuing the dying with superb medical skills， and serving the people. This spirit is passed down and developed in line with the times， characterized by political， people-centered， practical， and inheritable traits. The integration of virtue ethics elements with the red doctor spirit not only puts forward new virtue ethics requirements for this spirit in the new era but also provides corresponding pathways for the virtue ethics cultivation of the red doctor spirit.

BACKGROUND: Immunosuppression is closely related to the pathogenesis of sepsis, but the underlying mechanisms have not yet been fully elucidated. In this study, we aimed to examine the role of the Sterile Alpha Motif, Src Homology 3 domain and nuclear localization signal 1 (SAMSN1) in sepsis and elucidate its potential molecular mechanism in sepsis induced immunosuppression. METHODS: RNA sequencing databases were used to validate SAMSN1 expression in sepsis. The impact of SAMSN1 on sepsis was verified using gene knockout mice. Flow cytometry was employed to delineate how SAMSN1 affects immunity in sepsis, focusing on immune cell types and T cell functions. Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9)-mediated gene editing in RAW264.7 macrophages enabled interrogation of SAMSN1 's regulatory effects on essential macrophage functions, including cell proliferation and phagocytic capacity. The mechanism of SAMSN1 in the interaction between macrophages and T cells was investigated using the RAW264.7 cell line and primary cell lines. RESULTS: SAMSN1 expression was significantly increased in patients with sepsis and was positively correlated with sepsis mortality. Genetic deletion of Samsn1 in murine sepsis model improved T cell survival, elevated T cell cytolytic activity, and activated T cell signaling transduction. Concurrently, Samsn1 knockout augmented macrophage proliferation capacity and phagocytic efficiency. In macrophage, SAMSN1 binds to Kelch-like epichlorohydrin-associated protein 1 (KEAP1), causing nuclear factor erythroid 2-related factor 2 (NRF2) to dissociate from the KEAP1-NRF2 complex and translocate into the nucleus. This promotes the transcription of the coinhibitory molecules CD48/CD86/carcinoembryonic antigen related cell adhesion molecule 1 (CEACAM1), which bind to their corresponding receptors natural killer cell receptor 2B4/CD152/T cell immunoglobulin and mucin domain-containing protein 3 (TIM3) on the surface of T cells, inducing T-cell exhaustion. CONCLUSIONS SAMSN1 deletion augmented adaptive T cell immunity and macrophage phagocytic-proliferative dual function. Furthermore, it mediates the KEAP1-NRF2 axis, which affects the expression of coinhibitory molecules on macrophages, leading to T-cell exhaustion. This novel immunosuppression mechanism potentially provides a candidate molecular target for sepsis immunotherapy.

OBJECTIVE: To explore the effectiveness of arthroscopic release of elbow joint assisted by medial small incision ulnar nerve release in the treatment of non-traumatic elbow stiffness. METHODS: The clinical data of 15 patients with non-traumatic elbow stiffness treated with arthroscopic release of elbow joint assisted by medial small incision ulnar nerve release between April 2019 and September 2023 were retrospectively analyzed. There were 6 males and 9 females with an average age of 46 years ranging from 34 to 56 years. The causes included rheumatoid arthritis in 3 cases, gouty arthritis in 2 cases, loose bodies in 3 cases, and elbow osteoarthritis in 7 cases. There were 4 cases with ulnar neuritis and 3 cases with synovial osteochondromatosis. The duration of elbow stiffness ranged from 6 to 18 months, with an average of 10 months. The operation time and intraoperative blood loss were recorded. The effectiveness was evaluated by visual analogue scale (VAS) score, range of elbow motion (maximum flexion, maximum extension, and total flexion and extension), Mayo score, and Hospital for Special Surgery (HSS) elbow score. RESULTS: The operation time was 60-90 minutes, with an average of 65 minutes, and the intraoperative blood loss was 40-100 mL, with an average of 62 mL. All patients were followed up 13-18 months, with an average of 14 months. There was no complication such as vascular and nerve injury, poor wound healing, collateral ligament injury, elbow joint space narrowing, osteophyte proliferation, or loose body formation around the joint. At last follow-up, the elbow range of motion (maximum flexion, maximum extension, and total flexion and extension), VAS score, and Mayo score significantly improved when compared with those before operation ( P<0.05). The HSS elbow score was 85-95, with an average of 92; 12 cases were excellent, 3 cases were good, and the excellent and good rate was 100%. CONCLUSION Arthroscopic release of elbow joint assisted by medial small incision ulnar nerve release is an effective way to treat non-traumatic elbow stiffness, which has the advantages of small trauma, short operation time, and good effectiveness. It can carry out early elbow rehabilitation training and significantly improve elbow function.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective:To analyze the trend of dementia mortality rate among individuals aged 60 to 94 years in China from 1982 to 2021.Methods:Utilizing data from the Global Burden of Disease Study 2021, the Joinpoint regression model was employed to analyze the trend in the dementia mortality rate among Chinese older adults from 1982 to 2021. The age-period-cohort analysis method was used to decompose the age effect, period effect and cohort effect of dementia mortality data in Chinese elderly people.Results:From 1982 to 2021, the crude mortality rate of dementia in elderly women aged 60-94 in China (133.67/100 000-214.02/100 000) was higher than that in men (70.92/100 000-119.70/100 000), and the age-standardized mortality rate of dementia in women (230.74/100 000-246.87/100 000) was also higher than that in men (132.88/100 000-140.19/100 000). The age-standardized mortality rate of dementia in both genders showed an N-shaped fluctuation trend. The average annual percent change (AAPC) of dementia mortality rate in elderly males aged 60-94 was 0.07% (95% CI: 0.01%-0.13%), and the AAPC of dementia mortality rate in elderly females was -0.01% (95% CI:-0.08%-0.07%). Age effect analysis showed that from the age of 60, the risk of dementia death in males and females increased with age, especially among elderly people aged 75-94 who experienced a rapid increase in dementia mortality rate. The period effect analysis showed that the overall risk of dementia death in elderly men and women aged 60-94 was decreasing, but it had increased from 2017 to 2021. The cohort effect analysis showed that the risk of dementia death was lower in later birth cohorts. Conclusion:From 1982 to 2021, the dementia mortality rate among Chinese older adults aged 60 to 94 years exhibited fluctuations. Particularly, there has been a notable rebound in recent years. Special attention should be directed towards female seniors and those aged 75 to 94 years.

The computer network system is the core of a smart hospital,and the requirements for network architecture in the construction of large-scale smart hospitals are becoming increasingly high.Traditional network architectures with users moving with the network generally suffer from problems such as low installation efficiency,slow policy deployment speed,and easy confu-sion of asset accounts.When faced with complex network requirements in hospitals,they also face challenges such as poor net-work scalability and cumbersome management.Selecting appropriate network virtualization technology and building a new,high-speed,and reliable network architecture play a crucial role in promoting the development of large-scale smart hospitals.Starting from 2023,a large tertiary hospital in Guangzhou has built a new branch network project based on software-defined networking,showcasing the advantages of this architecture in terms of deployment speed,policy configuration,and endpoint management.Ex-perimental data ultimately shows that using a software-defined networking architecture can significantly improve the efficiency of policy deployment in hospital networks.

Objective:To investigate the related risk factors of surgical appendectomy after endoscopic retrograde appendicitis therapy (ERAT) in children.Methods:From September 2019 to November 2023 at the Children's Hospital Affiliated to Shandong University,the data from all related children with appendectomy after ERAT were analyzed. The general situation and main clinical manifestations of the children were collected. According to the effect of ERAT,the patients were divided into transfer to surgical group and appendicitis recurrence group by the reasons and time of transfer to surgical treatment. The indexes such as ERAT and reoperation process and pathological types of appendix after operation were collected,and the clinical experience was summarized.Results:Among the 242 children who underwent ERAT,32 cases underwent appendectomy again,including 19 males and 13 females,with an average age of（9.16±2.77）years,and the reoperation rate was 13.2%. The clinical manifestation was abdominal pain (32 cases,100.0%),mainly right lower abdominal pain (28 cases,87.5%),and the main duration was less than 3 months (30 cases,93.8%). Abdominal ultrasound or CT before ERAT mainly indicated appendicitis (11 cases,34.4%) and appendicitis complicated with appendiceal calculus (11 cases,34.4%). There were 9 children in transferred to surgical group,of which 5 cases were transferred to surgery because of ERAT intubation failure,and 4 cases were transferred to surgery because of appendix perforation or abscess. Postoperative pathology showed acute suppurative appendicitis in 5 cases and acute gangrenous appendicitis in 4 cases. There were 23 children in appendicitis recurrence group,whose abdominal pain was relieved after ERAT,but their symptoms were repeated after discharge. After clinical evaluation,they were diagnosed as recurrent appendicitis and underwent surgical appendectomy. Most of them were reoperated within 6 months after ERAT (21 cases,91.3%).Postoperative pathology was mainly chronic appendicitis (10 cases,43.5%).Conclusion:Acute suppurative appendicitis and acute gangrenous appendicitis are prone to catheterization or endoscopic failure during ERAT,and there is a high risk of surgical transfer. ERAT may relieve the symptoms of chronic appendicitis in children. If the symptoms are repeated,surgery is still needed to remove the appendix.
