Retinitis pigmentosa (RP) is the most common hereditary blinding eye disease in clinical practice, with the pathogenesis remaining unclear. Patients experience progressive apoptosis of retinal photoreceptor cells, accompanied by degeneration of retinal pigment epithelium (RPE) cells. Current Western medical treatments mainly focus on gene therapy and stem cell transplantation, showing limited efficacy. In contrast, clinical observations have confirmed the therapeutic effects of traditional Chinese medicine (TCM) treatments. Establishing an RP animal model that aligns with the diagnostic features of both TCM and Western medicine could help combine the strengths of both approaches, thereby broadening the treatment options for RP. This study categorizes and summarizes the existing RP animal models in terms of classification, types, inheritance patterns, and alignment with clinical manifestations. It is found that current RP models are primarily derived from natural animal models such as RD mice and RCS rats, transgenic animal models like RPE-65 knockout mice and rhodopsin gene knockout mice, and chemically induced models such as those created by monochromatic light exposure or N-ethyl-N-nitrosourea (ENU) administration. These three categories of models focus more on detecting RP-related histopathological, molecular biological, and cellular immunological indicators, but offer limited observation of the overall characteristics of the disease and lack insight into syndrome differentiation. Although RP is a congenital genetic disease, its progression is influenced by acquired factors such as environment, constitution, emotions, and care. Current models do not fully capture the characteristics of this disease. Therefore, establishing an RP animal model based on the diagnostic features of both TCM and Western medicine will have significant implications for future experimental and clinical research.

OBJECTIVE To formulate Guidelines for the standardized implementation of pharmacist-managed clinics ( 2026 edition ) in response to the challenges faced by such clinics in China, including uneven development, large discrepancies in service specifications, insufficient patient awareness, and limited medical insurance coverage. METHODS Led by the Pharmaceutical Affairs Professional Committee of the Chinese Hospital Association, the Evidence-based Pharmacy Professional Committee of the Chinese Pharmaceutical Association, and the Hospital Pharmacy Professional Committee of the Cross-strait Medical and Health Exchange Association, a total of 19 domestic hospital pharmacy experts were organized. Through a systematic review of national policies and literature research, current practical experience was summarized. Consensus on the contents of the guidelines was reached after in-depth discussions. RESULTS &CONCLUSIONS The guidelines covered five sections: definition and connotation of pharmacist-managed clinics, establishment requirements, implementation and management, post competency, and practical research. Firstly, the definition and connotation included three operational forms of pharmacist-managed clinics (independent mode, physician-pharmacist joint mode, and online pharmacist-managed clinic mode) and classified service modes (specialty-specific, drug-specific, and disease-specific pharmacist-managed clinics). The establishment requirements were further refined, covering system construction (pharmaceutical service management system, quality control and assessment mechanism), personnel qualifications (professional credentials, continuing education and professional training, etc), service recipients, as well as service venues and facilities. Subsequently, the implementation and management of pharmacist-managed clinics were proposed, involving service procedures, intervention measures, documentation and records, patient education and follow-up, humanistic care, as well as risk management and quality control. Finally, post competency encompassed the competency requirements for pharmacists providing services in pharmacist-managed clinics, as well as the suggestions on teaching methods; practical research encouraged the conduct of high-quality pharmaceutical practice in the setting of pharmacist-managed clinics. The guidelines provide valuable guidance for the standardized implementation of pharmacist-managed clinics in China in terms of establishment, management, teaching, and research, fill the guideline gap in this field, and can promote the high-quality development of pharmacist-managed clinics.

ObjectiveTo investigate the role of interleukin (IL)-17A in acute inhalational pneumonia induced by the highly drug-resistant and hypervirulent Staphylococcus aureus strain USA300-R in mice. MethodsAn acute inhalational pneumonia model was established in mice using an aerosolized pulmonary delivery technique. RNA sequencing (RNA-seq) and enzyme-linked immunosorbent assay (ELISA) were employed to examine the expression dynamics of Il17a mRNA and IL-17A protein, respectively, in the lungs of infected mice. Il17a knockout (Il17a-/-) mice were generated using CRISPR/Cas9 gene editing technology. The survival rate, body weight, bacterial load in lung tissue, and histopathological changes were compared between Il17a-/- and wild-type (WT) mice following inhalational infection with USA300-R. Results12 hours after USA300-R infection, compared to pre-infection, the expression level of Il17a mRNA in lung tissue and the level of IL-17A protein in bronchoalveolar lavage fluid (BALF) increased by approximately 50-fold (P<0.01) and 6-fold (P<0.001), respectively. Compared to WT mice, Il17a-/- mice exhibited approximately 10-fold higher bacterial loads in lung tissue at both 12 and 24 hours post-infection (P<0.001, P<0.05). However, they showed significantly attenuated lung histopathological injury, reduced alveolar wall thickening, markedly decreased neutrophil infiltration, and an approximately 50% improvement in survival rate (P<0.05). ConclusionIn acute Staphylococcus aureus USA300-R inhalational pneumonia, IL-17A contributes to bacterial clearance by recruiting neutrophils; however, excessive neutrophil infiltration exacerbates pulmonary inflammation and injury, reduces survival rates, and represents a potential therapeutic target.

Abstract
Obesity is characterized by a body weight exceeding a certain range and a corpulent physique, often accompanied by symptoms such as dizziness and fatigue, lack of energy and motivation to speak, reduced physical activity, and shortness of breath. The core pathogenesis of obesity lies in the dysfunction of the spleen and stomach in transporting and transforming nutrients, leading to abnormal metabolism of water and grain essences and the subsequent accumulation of pathological substances such as phlegm-dampness and "Gaozhuo" (greasy-turbid substances). Traditional Chinese Medicine emphasizes that "spleen deficiency is the root cause, while phlegm-dampness and Gaozhuo are the manifestations", forming a dialectical system encompassing theories on spleen-stomach transportation and transformation, phlegm-dampness pathogenesis, Gaozhuo pathogenesis, and constitutional differentiation. Traditional Chinese Medicine plays a crucial role in preventing and treating obesity through interventions such as herbal medicine, external therapies, and dietary adjustments. This article systematically reviews classical Chinese medical texts, focusing on the etiology, pathogenesis, theoretical origins, and prevention and treatment methods of obesity, so as to provide references for modern Traditional Chinese Medicine approaches to obesity prevention and treatment.

BACKGROUND:
Macrophage polarization anomalies and dysfunction play a crucial role in the pathogenesis of immune thrombocytopenia (ITP). Itaconate is a Krebs cycle-derived immunometabolite synthesized by myeloid cells to modulate cellular metabolism and inflammatory responses. This study aimed to evaluate the immunoregulatory effects of an itaconate derivative on macrophages in patients with ITP.
METHODS:
Peripheral blood-derived macrophages from patients with ITP and healthy controls were treated with 4-octyl itaconate (4-OI), a derivative of itaconate that can penetrate the cell membrane. Macrophage polarization, antigen-presenting functions, and phagocytic capability were measured via flow cytometry and enzyme-linked immunosorbent assay (ELISA). Macrophage glycolysis in patients with ITP and the metabolic regulatory effect of 4-OI were detected using a Seahorse XFe96 Analyzer. An active murine model of ITP was used to evaluate the therapeutic effects of 4-OI in vivo .
RESULTS:
4-OI reduced the levels of CD80 and CD86 in M1 macrophages and suppressed the release of tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 pro-inflammatory cytokines, suggesting that 4-OI could hinder the polarization of macrophages toward an M1 phenotype. We found that 4-OI pretreated M1 macrophages reduced the proliferation of CD4 + T cells and promoted the differentiation of regulatory T cells. In addition, after 4-OI treatment, the phagocytic capacity of M1 macrophages toward antibody-coated platelets decreased significantly in patients with ITP. In addition, the glycolytic function of M1 macrophages was elevated in individuals with ITP compared to those in healthy controls. 4-OI treatment downregulated glycolysis in M1 macrophages. The glycolysis inhibitor 2-deoxy-d-glucose (2-DG) also inhibited the polarization of M1 macrophages and restored their functions. In vivo , 4-OI treatment significantly increased platelet counts in the active ITP murine model.
CONCLUSIONS
Itaconate derivative 4-OI inhibited M1 macrophage polarization and restored impaired functions through metabolic reprogramming. This study provides a novel therapeutic option for ITP.

Objective:To investigate the association between social support and subjective and objective cognitive functions among the middle-aged and elderly population in Pingyin County, Jinan City, Shandong Province.Methods:Employing a multi-stage cluster random sampling method, a cross-sectional study was conducted in 2023 by selecting people aged 45-70 years from seven villages in three towns within Pingyin County, Jinan City, as survey respondents. Social Support Rating Scale (SSRS), Subjective Cognitive Decline-Questionnaire 9 (SCD-Q9) and Montreal Cognitive Assessment-Basic (MoCA-B) were used to assess the social support and cognitive status of interviewees, and a self-developed questionnaire was used to collect other basic information. Pearson correlation analysis, multiple linear regression and multifactorial logistic regression were used to explore the relationship between social support and subjective and objective cognitive functions.Results:A total of 1 891 subjects were finally included in the study, with 45.52±6.99 for the SSRS total score, an abnormal rate of 43.68% (826/1 891) for the SCD-Q9 score and an abnormal rate of 60.02% (1 135/1 891) for the MoCA-B score. The SSRS total score, subjective support score, objective support score and support utilization score were negatively correlated with SCD-Q9 scores and positively correlated with MoCA-B scores (all P<0.05). An increase in SSRS total score ( β=-0.034, 95% CI: -0.051--0.017, P<0.001) and objective support score ( β=-0.074, 95% CI: -0.121--0.027, P=0.002) can lower SCD-Q9 scores. Compared to those who had only 1 source of financial support or help with practical problems when experiencing an acute situation, those with 2-4 ( OR=0.53, 95% CI: 0.34-0.82), 5 ( OR=0.46, 95% CI: 0.27-0.79), or 6-7 ( OR=0.42, 95% CI: 0.22-0.81) sources of help were more likely to have normal SCD-Q9 scores. Compared to individuals with ≤2 close friends who provided support and help, those with 3-5 ( OR=0.67, 95% CI: 0.50-0.91) or ≥6 friends ( OR=0.72, 95% CI: 0.54-0.97) were more likely to have normal MoCA-B scores. Moreover, compared to individuals who never participated in group activities, those who actively participated ( OR=0.59, 95% CI: 0.42-0.81) were more likely to have normal MoCA-B scores. Conclusions:Social support has protective effects on subjective and objective cognitive functions, and various social support conditions have different protective effects on subjective and objective cognitive functions among middle-aged and older people. Improving social support conditions for middle-aged and elderly individuals may delay the process of cognitive decline.

Objective:To understand the evolution and variation characteristics of the H1N1 influenza virus in Wuxi City from 2018 to 2023.Methods:Real time PCR was used to perform nucleic acid testing on throat swab samples of influenza like cases sent to sentinel hospitals for testing. The influenza A (H1N1) pdm09 positive samples were subjected to cell culture, and nucleic acid was extracted from strains with a red blood cell agglutination test (HA) ≥1∶8. The whole genome sequence was amplified, and a library was constructed. The MiSeq sequencer was used for sequencing on the machine. Using NC_026431.1 as a reference strain, we analyzed the offline data using CLC Genomics Workbench (Version 23) software. MEGA 7.0 software was used to construct a phylogenetic tree, and NetNGlyc 1.0 Server software was used to predict N-glycosylation sites.Results:The nucleotide and amino acid homology between 38 strains of A (H1N1) pdm09 influenza virus from 2018 to 2023 were 96.06%-100% and 96.12%-100%, respectively. From February to May 2023, all 12 strains of A (H1N1) pdm09 had two amino acid mutation sites occurring in the HA antigenic determinant cluster, namely the Ca region (A203T) and the Cb region (K71Q). No mutations were found in the HA receptor binding site and NA resistance site. The strains from January to June 2018 belong to the 6B. 1A evolutionary branch, the strains from December 2018 to January 2020 belong to three evolutionary branches: 6B. 1A. 1, 6B. 1A. 5a, and 6B. 1A. 7, and the strains from February to May 2023 belong to the 6B. 1A. 5a. 2a evolutionary branch. 38 strains of A (H1N1) pdm09 HA gene all have 7 potential N-glycosylation sites, while NA gene has 7-8 potential N-glycosylation sites.Conclusions:There are characteristic amino acid mutation sites of H1N1 influenza A in Wuxi City from 2018 to 2023. The emergence of these mutation sites may affect the virus′s transmission and antigenic changes.

Objective :
To identify autophagy-related genes involved in pulmonary infection caused by the highly drug-resistant and virulent methicillin-resistant Staphylococcus aureus strain USA300 ( USA300) ,and to explore the underlying molecular mechanisms , thereby providing potential targets for immunotherapy.
Methods:
The GSE220943 dataset of a USA300-induced pulmonary infection mouse model was obtained from the GEO database. Differentially expressed genes ( DEGs ) were identified using the DESeq2 package. Autophagy-related genes ( ARGs) were retrieved from the MSigDB and Autophagy databases.Weighted gene co-expression network analysis ( WGCNA) was performed to construct gene co-expression modules.Genes overlapping among DEGs,ARGs,and WGCNA modules were identified as autophagy-related DEGs.Gene Ontology ( GO) enrichment analysis was con- ducted using the clusterProfiler R package,while Kyoto Encyclopedia of Genes and Genomes ( KEGG) pathway en- richment analysis was performed via the Metascape platform.Immune cell infiltration was analyzed using the Immu- CellAI-mouse website.A protein - protein interaction ( PPI) network was constructed using the STRING database, and hub genes were identified through topological analysis in Cytoscape. Receiver operating characteristic curve ( ROC) curves were plotted via the website https: / /www.bioinformatics.com.cn. Finally,key gene expression was validated in mouse lung tissues by real-time quantitative reverse transcription PCR ( RT-qPCR) .
Results:
A total of 6 135,4 075,3 680,and 2 342 differentially expressed genes ( DEGs) were identified at 12,24,48,and 96 hours post-infection,respectively.By integrating DEGs,autophagy-related genes ( ARGs) ,and WGCNA mod- ules,19 autophagy-related DEGs were identified. GO and KEGG enrichment analyses indicated that these genes were mainly involved in CD4 + T cell activation and regulation,innate immune responses,and autophagosome mem- brane formation.Immune infiltration analysis revealed that innate immune cells such as neutrophils and dendritic cells predominated during the early phase of infection,while γδ T cells and M2 macrophages became more promi- nent in the later stages.PPI network analysis identified 12 hub autophagy-related genes,among which three upreg- ulated key genes ( Eif2ak2,Ikbke,and Nfkbiz) were further confirmed.The area under the ROC curve for all three genes was 1. 000.RT-qPCR validation demonstrated significantly elevated expression of these three genes in lung tissues at 24 hours post-infection ( all P<0. 05) .
Conclusion
Eif2ak2,Ikbke,and Nfkbiz may be involved in the pulmonary infection caused by USA300 by promoting autophagy and hold promise as potential targets for immuno- therapy.

Objective:To construct an indicator system for entrustable professional activities (EPAs) in the general practice enhancement stage of pediatric specialist physician training.Methods:A draft indicator system for EPAs in the general practice enhancement stage of pediatric physician training was developed through core EPAs working group discussion, literature review, nominal group discussion, and expert consultation. Subsequently, the indicator system was preliminarily implemented and revised.Results:The core EPAs working group consisted of nine specialist physician trainers. In the initial brainstorming stage, a "potential list" of 30 activities was established. After literature review and collation, the draft indicator system included eight EPAs. Through nominal group discussion, the connotation of the draft was enriched, and the importance of the EPAs was ranked and modified. Finally, through expert consultation, the EPAs for the general practice enhancement stage of pediatric specialist physician training were determined. These included basic operations for the treatment of critically ill children, identification and management of critical illnesses, referral of critically ill children, perioperative management, in-hospital consultation, medical and teaching management and system improvement, doctor-patient communication and dispute handling, and response to public health events. During the preliminary implementation stage, a total of nine specialist physicians who participated in the training were evaluated. Based on the problems found in the pre-evaluation, the indicators of EPAs were revised, and a corresponding curriculum training system was developed.Conclusions:Through multiple rounds of nominal group discussion and expert consultation, the indicator system for EPAs in the general practice enhancement stage of pediatric specialist physician training was formulated. The system was preliminarily implemented and revised, and a curriculum system was constructed.
