In recent years, the incidence of dry eye disease(DED)is increasing, positioning it as one of the most prevalent diseases affecting the ocular surface. Inflammatory response is the pathological basis of DED, involving various inflammatory mediators and inflammatory signaling pathways. Consequently, anti-inflammatory treatment emerges as a fundamental strategy for preventing and managing DED. This review summarizes the classic inflammatory factors involved in the development and progression of DED, including interleukins, tumor necrosis factor, matrix metalloproteinases, chemokines, and cell adhesion molecules. It also discusses the relevant inflammatory signaling pathways: the MAPKs pathway, NF-κB pathway, Wnt pathway and TLR pathway. Additionally, this review addresses the mechanisms of action and alterations in relevant biomarkers associated with current first-line recommended anti-inflammatory therapies, including corticosteroids, immunosuppressants, nonsteroidal anti-inflammatory drugs, and traditional Chinese medicine approaches to inflammation management. This comprehensive overview aims to enhance understanding of the inflammatory mechanisms underlying DED while exploring future therapeutic prospects.

OBJECTIVE To develop the quality evaluation standard indicator system for hospital cough and wheeze pharmaceutical care clinic (CWPC) pharmacist training within the layered learning practice model (LLPM), and apply it in clinical practice. METHODS Our teaching team established an LLPM model to train cough and wheeze pharmacists, according to the actual conditions of our college. Using qualitative interview methods, expert questionnaires were compiled with literature research; the expert correspondence methods were employed to conduct two rounds of consultation with 10 domestic respiratory medicine experts, thus constructing an evaluation index system for the teaching quality of cough and wheeze pharmacists. The experts’ positive coefficient, authority coefficient, Kendall’s harmony coefficient, and the degree of concentration of opinions were calculated. The analytic hierarchy process (AHP) was used to determine the weight of each indicator within the index system. From June 2023 to June 2024, the teaching team enrolled 21 pharmacists in the training program. The teaching team assessed and scored the trial group (LLPM) and control group (traditional teaching model) based on the benefit indicators for pharmacists and patients in the evaluation index system, and compared the results. RESULTS This study explored the establishment of a training system for cough and wheeze pharmacists under the LLPM model, and initially established an evaluation index system using the Delphi method. In two rounds of Delphi method questionnaires, the recovery rate was 100%, with an authority coefficient exceeding 0.8, Kendall’s harmony coefficient ranging from 0.235 to 0.459, and all P-values being less than 0.05. Four primary (comprising trainee feedback, learning gains, behavioral improvements, and training performance), 12 secondary and 33 tertiary indicators were finalized. In the empirical evaluation, the results of the two groups showed a significant benefit to the pharmacists in the trial group. Specifically, the percentage of patients receiving corticosteroids for COPD or wheeze service patients per month (80.5%), an average increase in the number of cough and wheeze team service outpatient visits per month (compared to the same period of the previous year) of 14.8 visits per month, and the patient satisfaction score (4.9) were all significantly higher than those in the control group (P<0.05). CONCLUSIONS The application of the LLPM in competency training for pharmacists specializing in cough and wheeze care yields multiple benefits and holds significant guiding value. The constructed training quality evaluation index system under this model is scientific and reliable.

Liver fibrosis is a vital cause of morbidity in patients with liver diseases and developing novel anti-fibrotic drugs is imperative. Isovalerylspiramycin I (ISP I) as a major component of carrimycin applied to upper respiratory infections, was first found to possess anti-fibrotic potential. The present study aims to evaluate the functions and mechanisms of ISP I in protecting against liver fibrosis. According to our results, ISP I not only reduced the expressions of fibrogenic markers in LX-2 cells but also appeared great protective effects on liver injury and liver fibrosis in bile duct ligation (BDL) rats and carbon tetrachloride (CCl4) mice. We proved that nucleotide-binding protein 2 (NUBP2) was the direct target of ISP I. ISP I through targeting NUBP2, increased the amount of vascular non-inflammatory molecule-1 (VNN1) on the cell membrane, which will inhibit oxidative stress and fibrosis. Simultaneously, the original carrimycin's protective effect on liver damage and fibrosis was verified. Therefore, our study provides potential agents for patients with liver fibrosis-related diseases, and the clear mechanism supports wide application in the clinic.

Medicine is the subject of studying human and its inherent humanistic attribute endows medicine with the temperature it deserves. However, with the continuous improvement of medical testing technology and treatment technology, medical workers pay more attention to diseases and ignore humanistic care, which has become an important factor in the aggravation of patients’ burden and the tension relationship between doctors and patients. There are many virtues in Chinese traditional culture. Sun Simiao’s medical ethics thought of "great doctor with professionalism and sincerity" embodies the core value of the humanistic spirit of Chinese traditional medicine. In his medical ethics thought, the moral and ethics of "great doctor with professionalism and sincerity", the medical practice attitude of "being cautious and diligent", the values of "benevolence for the world" and the professional conduct of "honesty and truth" still have strong practical significance at present. It is the good material to cultivate the humanistic spirit of medical students. This is of great value to integrate Sun Simiao’s medical ethics thought into cultivate medical students with both "professionalism" and "sincerity", practice the original intention of medical and health undertakings, and carry forward cultural self-confidence.
