Heparin-binding protein (HBP) is a pro-inflammatory granule protein released by activated neutrophils, known for its role in modulating vascular permeability and its pathological significance in infectious diseases. In recent years, HBP has garnered attention due to its immune-activating effects in contexts such as sepsis, acute lung injury and organ transplantation. It has been proposed as a potential biomarker for early detection of infection and inflammation. While preliminary progress has been made in animal studies, clinical evidence remains limited. Therefore, this article focuses on the mechanism of action of HBP in transplantation-related complications, explores its potential pathways for predicting infection risk, mediating ischemia-reperfusion injury and rejection, and evaluates the feasibility of intervention strategies such as neutralizing antibodies, heparin derivatives and albumin. The pivotal role of HBP in regulating inflammatory responses post-transplant may offer a novel target for postoperative infection monitoring and personalized therapeutic interventions.

Obesity is an important manifestation of the imbalance of energy regulation, and its complications can cause irreparable damage to the body. Finding the pathogenesis of obesity at the molecular level can help fundamentally avoid these irreversible complications. Extended synaptotagmins (E-Syts) are proteins related to the formation of endoplasmic reticulum (ER) and plasma membrane (PM). Because of the short discovery time, there is huge room for exploration. In terms of the role of the established structure of E- Syts at the molecular level, it has a non-negligible link with the pathogenesis of obesity. Starting with the structure of hypothalamus, this paper reviews the literature evidence of this connection, hoping to find a new research angle for reducing the incidence of obesity.

Rheumatoid arthritis belongs to arthralgia syndrome in the theory of traditional Chinese medicine， and cold-dampness obstruction syndrome and dampness-heat obstruction syndrome are core syndromes and main syndrome differentiation types of this disease. Fine therapeutic effects have been obtained in the long-term clinical practice of many famous traditional Chinese medicine practitioners following the syndrome differentiation and treatment based on the guiding principles of cold and heat. To adapt to the clinical diagnosis practice of combining disease differentiation and syndrome differentiation， and to better carry out basic research on integrated Chinese and Western medicine and preclinical study on new traditional Chinese medicines， Guidelines for Establishing Animal Models of Rheumatoid Arthritis with Cold-Dampness Obstruction Syndrome and Dampness-Heat Obstruction Syndrome （hereinafter referred to as the Guidelines） were compiled by our research group， in cooperation with the renowned experts in research fields including traditional Chinese medicine， clinical medicine， zoology and evidence-based medicine， which provide a meaningful reference for scientific research， teaching and clinical applications. The compilation process of the Guidelines was guided by the theory of disease and syndrome integration and the principles of "evidence takes the main place， consensus plays an auxiliary role， and experience serves as the reference". Based on the comprehensive evaluation of pathogenesis homology， behavioral phenotypic consistency， and drug treatment predictability compared between animal models and human diseases， by the nominal group method， "recommendations" were formed for recommendations supported by evidence， and "consensus recommendations" were formed for recommendations not supported by evidence. Guidelines were formed involving content such as animal types， arthritis modeling methods， external stimulation conditions， and modeling assessment indicators during the establishment of the animal models of rheumatoid arthritis with cold-dampness obstruction syndrome and dampness-heat obstruction syndrome. The Guidelines are applicable for the disease and syndrome research on rheumatoid arthritis， investigation of therapeutic mechanisms， and development of new traditional Chinese medicine. The Guidelines also provide a reference for the establishment of guidelines on other types of diseases and syndromes combined with animal models to further promote the modernization of traditional Chinese medicine research and its integration with international academic development.

The Guidelines for Establishing Animal Models of Rheumatoid Arthritis with Cold-dampness Obstruction Syndrome and Dampness-heat Obstruction Syndrome （hereinafter referred to as the Guidelines） （No. T/CACM1567-2024） was published by Chinese Association of Chinese Medicine on January 11， 2024. To assist researchers and medical workers in understanding and applying the Guidelines more accurately， and also to provide reference and assistance for the establishment of guidelines on other types of diseases and syndromes combined with animal models， this paper made a declaration of the workflow， technological links， development references， promotion of its application and after-effect evaluation of the Guidelines that has been made according to the requirements of "Draft Group Standard of the Standardization Office of the Chinese Association of Traditional Chinese Medicine".

Background Work-related musculoskeletal disorders (WMSDs) are one of the major occupational health problems faced by bus drivers and should receive special attention. Objective To explore the associations of weekly working hours and sleep quality with neck and lower back WMSDs among bus drivers, as well as assess the potential mediating role of sleep quality. Methods From June to December 2022, we recruited bus drivers from 5 subsidiaries of the Shenzhen Bus Group by convenient sampling method. Demographic characteristics, lifestyles, and work-related features of the bus drivers were collected through a questionnaire survey. The Pittsburgh Sleep Quality Index (PSQI) scale and the Musculoskeletal Disorders Survey Questionnaire were used to assess sleep quality and WMSDs respectively. Logistic regression models were applied to analyze the associations of weekly working hours and sleep quality with WMSDs in neck and lower back. Furthermore, mediation analysis was performed to investigate the role of sleep quality in the associations between weekly work hours and neck and lower back WMSDs. Results A total of 1792 valid questionnaires were collected, with a response rate of 95.07%. Among these, 89.3% of the bus drivers worked more than 40 h per week, and the positive rate of poor sleep quality was 28.2%. The overall positive rate of WMSDs within one year before the survey was 69.12%. Among different body regions, the leading positive rates were identified in neck and lower back regions, at 55.92% and 53.68%, respectively. The logistic regression model showed that compared to the bus drivers with weekly work hours ≤40 h, those weekly worked (40~48] h (OR=1.43, 95%CI: 1.02, 2.01; OR=1.65, 95%CI: 1.17, 2.34), (48~56] h (OR=2.69, 95%CI: 1.89, 3.83; OR=2.30, 95%CI: 1.62, 3.29) and ＞56 h (OR=2.63, 95%CI: 1.86, 3.74; OR=3.23, 95%CI: 2.27, 4.62) had significantly increased risk of WMSDs in neck and lower back. Additionally, when compared to those with good sleep quality, bus drivers with poor sleep quality had higher risks of both neck and lower back WMSDs (OR=4.08, 95%CI: 3.20, 5.23; OR=4.15, 95%CI: 3.26, 5.30, respectively). Further mediation analysis indicated that sleep quality partially mediated the associations between weekly working hours and both neck and lower back WMSDs, with 36.15% and 33.68% as the respective proportion of mediation. Conclusion The positive rate of WMSDs is high among bus drivers, and the most common WMSDs occur in neck and lower back. Long working hours and poor sleep quality are significantly associated with increased risks of neck and lower back WMSDs. Sleep quality may mediate the associations of weekly working hours with neck and lower back WMSDs.

Ocular surface squamous neoplasia(OSSN)is a series of pathological solid tumors formed by dysplasia of keratoconjunctival epithelium, which is one of the most common ocular surface tumors in adults. In the past two decades, the treatment of OSSN has gradually changed from surgical resection to topical chemotherapy. Interferons, 5-fluorouracil and mitomycin are the most commonly used topical agents for the clinical treatment of this disease. This paper summarizes the diagnosis of OSSN and various local chemotherapy treatment options, highlights the potential role of high-resolution optical coherence tomography(HR-OCT)technology in the diagnosis and treatment of this disease.

Background With the continuous development of the healthcare industry, healthcare workers face increasing pressure, including long-term shift work and workplace violence from patients or their relatives. This not only affects the physical and mental health of healthcare workers but may also negatively impact the quality of patient care and the efficiency of medical services. Objectives To analyze the pathways through which shift work and workplace violence affect healthcare workers' self-rated health and depression symptoms, explore potential mediating role of job burnout, and conduct subgroup analyses to reveal differences among various groups. Methods Data were collected from 3706 frontline healthcare workers across 23 provinces from January 10 to February 5, 2019, using a snowball sampling method. The survey included basic demographic information, self-rated health, depression symptoms [assessed using the Patient Health Questionnaire-2 (PHQ-2)], workplace violence experience assessed using the Workplace Violence Scale), and job burnout (assessed using the Chinese Maslach Burnout Inventory). Data were analyzed using logistic regression, structural equation modeling (for mediating effects), and subgroup analysis to examine the impacts of shift work and workplace violence on health and depression symptoms. Results Among the subjects, 2700 workers (73.29%) reported shift work experience, 2079 workers (56.43%) experienced workplace violence, 633 workers (17.18%) reported poor self-rated health, and 687 workers (18.65%) reported depression symptoms. Shift work was associated with self-rated health (OR=0.572, 95%CI: 0.461, 0.710) and depression symptoms (OR=1.519, 95%CI: 1.190, 1.938), while workplace violence also associated with self-rated health (OR=0.566, 95%CI: 0.471, 0.681) and depression symptoms (OR=2.096, 95%CI: 1.740, 2.525). Job burnout significantly mediated the effects of shift work and workplace violence on self-rated health (indirect effects: −0.023, −0.027) and depression symptoms (indirect effects: 0.032, 0.037) (all P < 0.001). The subgroup analysis revealed that age, marital status, physical exercise, smoking, and alcohol consumption influenced the impacts of shift work and workplace violence on health. Conclusion Shift work and workplace violence significantly affect healthcare workers' self-rated health and depression symptoms, with job burnout playing a key mediating role in this process. This suggests that healthcare institutions should improve resource allocation, provide flexible scheduling systems, ensure adequate rest time, and increase psychological support and safety measures to help healthcare workers better cope with work-related stress and violence.
