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 explore the mechanisms of Yangjing Tongluo prescription (YJTL) in the treatment of intrauterine adhesion (IUA) from the perspective of oxidative stress mediated by the Kelch-like ECH-associated protein 1/nuclear factor erythroid 2-related factor 2/heme oxygenase-1 (Keap1/Nrf2/HO-1) signaling pathway. MethodsA total of 48 rats with normal estrous cycles were selected and randomly divided into a normal group (n=8) and a modeling group (n=40). An IUA rat model was established using a dual-injury method combining surgical curettage and infection. Eight rats were randomly selected from the modeling group for a pilot experiment to confirm successful model establishment. After successful modeling, the remaining 32 rats were randomly divided into a model group, a low-dose YJTL group (YJTL-L), a high-dose YJTL group (YJTL-H), and a Progynova group. Rats in the normal and model groups were administered purified water (15 mL·kg-1) by gavage daily, while rats in the YJTL-L, YJTL-H, and Progynova groups received YJTL at doses of 6.43 and 12.86 g·kg-1 and Progynova at 2.06 × 10-4 g·kg-1, respectively, for 14 consecutive days. The general condition, uterine morphology, and uterine index of the rats were monitored. Histopathological changes in uterine tissue were observed using hematoxylin-eosin (HE) staining. Serum levels of reactive oxygen species (ROS) and glutathione peroxidase (GSH-Px) were measured by enzyme-linked immunosorbent assay (ELISA). Protein expression levels of Keap1, Nrf2, and HO-1 in endometrial tissue were detected by Western blot. Immunofluorescence (IF) was used to assess the distribution of Nrf2 and HO-1, as well as the expression of Nrf2 in the cytoplasm and nucleus. ResultsCompared with the normal group, rats in the model group exhibited poor mental status and reduced mobility, markedly edematous and tortuous uterine morphology, decreased gland number, and inflammatory reactions in the endometrium, along with an increased uterine organ index (P<0.05). Serum ROS levels were significantly increased (P<0.05), while serum GSH-Px levels were significantly decreased (P<0.05). In endometrial tissue, Keap1 protein expression was increased (P<0.05), whereas Nrf2 and HO-1 protein expression was decreased. Mild nuclear translocation of Nrf2 was observed, accompanied by increased relative fluorescence intensity of nuclear Nrf2 and decreased relative fluorescence intensity of cytoplasmic HO-1. Compared with the model group, all treatment groups showed varying degrees of improvement in the above symptoms and pathological changes. Serum ROS levels were reduced (P<0.05), serum GSH-Px levels were increased (P<0.05), Keap1 protein expression in endometrial tissue was decreased, and Nrf2 and HO-1 protein expression was increased in a dose-dependent manner (P<0.05). Notably, significant nuclear translocation of Nrf2 was observed, with correspondingly increased relative fluorescence intensity of nuclear Nrf2 and enhanced relative fluorescence intensity of cytoplasmic HO-1. ConclusionYJTL may enhance antioxidant capacity and repair oxidative damage to the endometrial basal layer by regulating the Keap1/Nrf2/HO-1 signaling pathway.

ObjectiveTo explore the mechanism by which Sini San (SNS) inhibits ferroptosis, alleviates inflammation and myocardial injury, and improves myocardial infarction (MI). MethodsThe active ingredients of SNS were obtained by searching the Traditional Chinese Medicine System Pharmacology Platform (TCMSP) database, its target sites were predicted using the SwissTargetPrediction Database, and the core components were screened out using the CytoNCA plug-in. The targets of MI and ferroptosis were obtained by using GeneCards, Online Mendelian Inheritance in Man (OMIM) database, DrugBank, Therapeutic Target Database (TTD), FerrDb database and literature review, respectively. The intersection of these targets of SNS-MI-ferroptosis was plotted as a Venn diagram. The protein-protein interaction (PPI) network was constructed using the STRING database, and the visualization graph was prepared using Cytoscape. The core targets were screened out using the CytoNCA plug-in, and the biological functions were clustered by the MCODE plug-in. Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed using the David database. Molecular docking was performed using AutoDock and visualized with PyMOL2.5.2. The Kunming mice were randomly divided into the control group, the model group, the SNS group, and the trimetazidine (TMZ) group. The mice were subcutaneously injected with isoprenaline (ISO, 5 mg·kg-1·d-1) to establish an MI model. The drug was continuously intervened for 7 days. The ST-segment changes were recorded by electrocardiogram (ECG), and the tissue morphology changes were observed by hematoxylin-eosin (HE) staining. Cardiomyocyte ferroptosis was investigated by transmission electron microscopy. Serum creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactate dehydrogenase (LDH), reduced glutathione (GSH), and malondialdehyde (MDA) levels were detected by biochemical assay. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of interleukin (IL)-6 and 4-hydroxynonenal (4-HNE). Immunohistochemical staining was employed to detect IL-6 and phosphorylated signal transducer and transcription activator 3 (p-STAT3) in cardiac tissues. Western blot was used to detect STAT3 and p-STAT3 in cardiac tissues. Real-time PCR was used to detect the levels of IL-6, IL-18, solute carrier family 7 member 11 (SLC7A11), arachidonic acid 15-lipoxygenase (ALOX15), and glutathione peroxidase 4 (GPx4) in cardiac tissues. ResultsA total of 121 active ingredients of SNS were obtained, and 58 potential targets of SNS in the treatment of MI by regulating ferroptosis were screened. The three protein modules with a score5 were mainly related to the inflammatory response. The GO function was mainly related to inflammation, and KEGG enrichment analysis showed that SNS mainly regulated ferroptosis- and inflammation- related signaling pathways. Molecular docking indicated that the core component had a higher binding force to the target site. Animal experiments confirmed that SNS reduced the level of p-STAT3 (P0.01), down-regulated the expression of ALOX15 mRNA (P0.01), up-regulated the level of serum GSH, and the expressions of SLC7A11 and GPx4 mRNA, reduced MDA and 4-HNE levels (P0.05, P0.01). Additionally, SNS improved the mitochondrial injury induced by cardiomyocyte ferroptosis, reduced the area of MI, alleviated inflammation and myocardial injury, lowered the levels of serum CK, CK-MB, LDH, IL-6, and the mRNA expression levels of IL-16 and IL-18 (P0.05), and improved ST segment elevation. ConclusionSNS can reduce ISO-induced STAT3 phosphorylation levels, inhibit ferroptosis in cardiomyocytes, alleviate inflammation and myocardial injury, thereby improving MI.

OBJECTIVE To construct an intelligent pharmaceutical Q&A platform for precision medication with low “artificial intelligence (AI) hallucination”, aiming to enhance the accuracy, consistency, and traceability of medication consultations. METHODS Medication package inserts were batch-processed and converted into structured data through Python programming to build a local pharmaceutical knowledge base. The retrieval and question-answering processes were designed based on large language models, and system integration and localized deployment were completed on Dify platform. By designing typical clinical medication questions and comparing the output of the intelligent pharmaceutical Q&A platform with the online version of DeepSeek across dimensions such as peak time retrieval, half-life, and dosage adjustment reasoning for patients with renal impairment, the accuracy and reliability of its retrieval and reasoning results were evaluated. RESULTS The intelligent pharmaceutical Q&A platform, constructed based on local drug package inserts, achieved 100% accuracy in retrieval and reasoning for peak time, half-life, and dosage adjustment schemes. In comparison, the online version of DeepSeek demonstrated accuracies of 30%(6/20), 50%(10/20), and 38%(23/60) across these three dimensions, respectively. CONCLUSIONS The constructed intelligent pharmaceutical Q&A platform is capable of accurately retrieving and extracting information from the local knowledge base based on clinical inquiries, thereby avoiding the occurrence of AI hallucinations and providing reliable medication decision support for healthcare professionals.

ObjectiveTo elucidate the expression patterns of CYHR1 in colorectal cancer (CRC) and its regulatory role in tumour cell proliferation and metastasis-related phenotypes. MethodsExpression differences of CYHR1 between colorectal cancer tissues and adjacent normal tissues were analyzed using data from The Cancer Genome Atlas (TCGA) database, and the association between CYHR1 expression and patient survival was evaluated. A CRC cell model with CYHR1 overexpression was established, and changes in the expression of related molecules were verified by quantitative real-time PCR (qRT-PCR). Cell proliferation and metastatic potential were assessed using MTT assays, colony formation assays, and Transwell migration and invasion assays to evaluate the effects of CYHR1 and MALAT1 on CRC cell proliferation and migration/invasion, including combined intervention experiments. ResultsDatabase analysis revealed that CYHR1 is significantly overexpressed in CRC tissues, and that this overexpression is significantly associated with poorer overall survival. Compared with normal control cells, mRNA expression levels of CYHR1 were markedly elevated in CRC cell lines (HCT116, RKO, etc.) (P=0.002; P=0.006). Functional experiments demonstrated that CYHR1 overexpression significantly promoted the proliferation (P<0.001), colony formation (P<0.001), migration (P=0.002) and invasive capacity (P=0.002) of HCT116 cells; whereas knockdown of either CYHR1 or MALAT1 inhibited CRC cell proliferation and reduced their migration (P=0.006) and invasive capacity (P=0.006). In the context of CYHR1 overexpression, combined knockdown of MALAT1 partially reversed the promotional effect of CYHR1 on CRC cell proliferation, migration and invasion (P<0.001; P=0.001). Mechanistic studies further revealed that CYHR1 overexpression upregulates MALAT1 mRNA expression levels (P<0.001), whilst CYHR1 knockdown leads to downregulation of MALAT1 expression (P<0.001); MALAT1 knockdown likewise downregulates CYHR1 expression, suggesting a mutually reinforcing positive regulatory relationship between the two. Furthermore, CYHR1 can activate the IL-6/STAT3 signalling axis, whilst knockdown of IL-6 or STAT3 inhibited the upregulation of MALAT1 expression by CYHR1 (P=0.031; P=0.006). ConclusionCYHR1 is abnormally overexpressed in colorectal cancer and is closely associated with poor prognosis. CYHR1 may promote the proliferation, migration, and invasion of colorectal cancer (CRC) cells by activating the IL-6/STAT3/MALAT1 axis.

OBJECTIVE To investigate the effect and mechanism of Jingangteng capsules in the treatment of non-alcoholic fatty liver disease (NAFLD). METHODS Thirty-two SD rats were randomly divided into normal group and modeling group. The modeling group was fed a high-fat diet to establish a NAFLD model. The successfully modeled rats were then randomly divided into model group, atorvastatin group[positive control, 2 mg/(kg·d)], and Jingangteng capsules low- and high-dose groups [0.63 and 2.52 mg/(kg·d)], with 6 rats in each group. The pathological changes of the liver were observed by hematoxylin-eosin staining and oil red O staining. Enzyme-linked immunosorbent assay was performed to determine the serum levels of triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), alanine transaminase (ALT), aspartate transaminase (AST), tumour necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, IL-18. 16S rDNA amplicon sequencing and metabolomics techniques were applied to explore the effects of Jingangteng capsules on gut microbiota and metabolisms in NAFLD rats. Based on the E-mail:591146765@qq.com metabolomics results, Western blot analysis was performed to detect proteins related to the nuclear factor kappa-B (NF-κB)/NOD-like receptor family protein 3 (NLRP3) signaling pathway in the livers of NAFLD rats. RESULTS The experimental results showed that Jingangteng capsules could significantly reduce the serum levels of TG, TC, LDL-C, AST, ALT, TNF-α, IL-1β, IL-6, IL-18, while increased the level of HDL-C, and alleviated the hepatic cellular steatosis and inflammatory infiltration in NAFLD rats. They could regulate the gut microbiota disorders in NAFLD rats, significantly increased the relative abundance of Romboutsia and Oscillospira, and significantly decreased the relative abundance of Blautia (P<0.05). They also regulated metabolic disorders primarily by affecting secondary bile acid biosynthesis, fatty acid degradation, O-antigen nucleotide sugar biosynthesis, etc. Results of Western blot assay showed that they significantly reduced the phosphorylation levels of NF-κB p65 and NF-κB inhibitor α, and the protein expression levels of NLRP3, caspase-1 and ASC (P<0.05 or P<0.01). CONCLUSIONS Jingangteng capsules could improve inflammation, lipid accumulation and liver injury in NAFLD rats, regulate the disorders of gut microbiota and metabolisms, and inhibit NF-κB/NLRP3 signaling pathway. Their therapeutic effects against NAFLD are mediated through the inhibition of the NF-κB/NLRP3 signaling pathway.

ObjectiveTo explore the role of lead exposure in the phenotypic transformation of vascular smooth muscle cells (VSMC), and to provide new insights for the mechanism of lead impact on vascular lesions. MethodsMouse aortic smooth muscle cells (MOVAS) were divided into a control group (0 μmol·L-1), low concentration lead groups (0.1, 1, 5, and 10 μmol·L-1), and high concentration lead groups (15, 25, and50 μmol·L-1). MTT assays were used to assess the proliferation of the cells, and scratch assays were implicated to measure migration ability of the cells. Fluorescence quantitative PCR was employed to determine levels of mRNA expression for smooth muscle actin α (α⁃SMA), smooth muscle 22 alpha (SM22α), synthetic phenotype-related genes osteopontin (OPN), matrix metalloproteinase 9 (MMP9), and the transcription factor SOX9. Immunoblotting was used to determine levels of protein expression for α-SMA, OPN, and MMP9. ResultsProliferation of MOVAS was observed under the lead ions concentrations of 0‒50 µmol·L-1, with a significant increase of proliferation compared to the control group at the concentrations of 5‒50 µmol·L-1 (all P<0.05). The migration ability of cells gradually increased at the concentrations of 0‒10 µmol·L-1, with a significant increase at 5 (q=4.574, P=0.003) and 10 µmol·L-1 (q=10.570, P<0.001) compared to the control group. The 10 µmol·L-1 lead ions significantly reduced the levels of mRNA expression for vascular smooth muscle contractile phenotype genes α⁃SMA (q=7.426, P<0.001) and SM22α (q=4.766, P=0.001), while significantly increasing the levels of mRNA expression for OPN (q=11.330, P<0.001), MMP9 (q=7.842, P<0.001), and SOX9 (q=11.120, P<0.001) genes. Furthermore, the 10 µmol·L-1 lead ions significantly reduced the levels of protein expression for the vascular smooth muscle contractile phenotype marker α-SMA protein (q=2.897, P=0.049), while significantly increasing the levels of protein expression for the synthetic markers OPN (q=3.188, P=0.031) and MMP9 (q=3.292, P=0.026), compared to the control group. ConclusionTreatment with lead in vitro induced VSMC to differentiate from contractile phenotype to synthetic phenotype, indicating that a certain dose of lead exposure might be detrimental to the cardiovascular system.

Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.

Vascular damage plays a significant role in the onset and progression of Alzheimer's disease (AD). However, the precise molecular mechanisms underlying the induction of neuronal injury by vascular damage remain unclear. The present study aimed to examine the impact of fibrinogen (Fg) on tau pathology. The results showed that Fg deposits in the brains of tau P301S transgenic mice interact with tau, enhancing the cytotoxicity of pathological tau aggregates and promoting tau phosphorylation and aggregation. Notably, Fg-modified tau fibrils caused enhanced neuronal apoptosis and synaptic damage compared to unmodified fibrils. Furthermore, intrahippocampal injection of Fg-modified tau fibrils worsened the tau pathology, neuroinflammation, synaptic damage, neuronal apoptosis, and cognitive dysfunction in tau P301S mice compared to controls. The present study provides compelling evidence linking Fg and tau, thereby connecting cerebrovascular damage to tau pathology in AD. Consequently, inhibiting Fg-mediated tau pathology could potentially impede the progression of AD.
