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.

Iron metabolism is a critical factor in tumorigenesis and development. Although TP53 mutations are prevalent in glioblastoma (GBM), the mechanisms by which TP53 regulates iron metabolism remain elusive. We reveal an imbalance iron homeostasis in GBM via TCGA database analysis. TP53 mutations disrupted iron homeostasis in GBM, characterized by elevated total iron levels and reduced ferritin (FTH). The gain-of-function effect triggered by TP53 mutations upregulates itchy E3 ubiquitin-protein ligase (ITCH) protein expression in astrocytes, leading to FTH degradation and an increase in free iron levels. TP53-mut astrocytes were more tolerant to the high iron environment induced by exogenous ferric ammonium citrate (FAC), but the increase in intracellular free iron made them more sensitive to Erastin-induced ferroptosis. Interestingly, we found that Erastin combined with FAC treatment significantly increased ferroptosis. These findings provide new insights for drug development and therapeutic modalities for GBM patients with TP53 mutations from iron metabolism perspectives.

AIM:This study aims to investigate the mechanism by which LINC00973 regulates multidrug re-sistance of non-small-cell lung cancer(NSCLC).METHODS:The GEPIA database was employed to analyze the expres-sion levels of LINC00973 in NSCLC and its correlation with patient prognosis in clinical settings.RT-qPCR was utilized to assess LINC00973 expression in various NSCLC cell lines and chemoresistant cells.The migration,invasion,stemness ca-pacity,and drug sensitivity of NSCLC cells with either overexpression or knockdown of LINC00973 were evaluated using wound healing assay,Transwell assay,sphere formation assay,and CCK-8 assay.RNA sequencing was conducted on LINC00973-overexpressing and parental NSCLC cells to identify dysregulated pathways and targets.The LncBase Pre-dicted v.2 and TargetScan databases were used to predict the microRNAs(miRNAs)co-bound by LINC00973 and their target genes.Mimics and inhibitors of candidate miRNAs were synthesized and transfected into NSCLC cells subjected to LINC00973 overexpression or knockdown.Changes in the expression level of LINC00973,and the mRNA and protein ex-pression levels of its target genes were assessed using RT-qPCR and Western blot.RESULTS:Analysis of the GEPIA da-tabase revealed that LINC00973 was significantly up-regulated in lung adenocarcinoma and lung squamous cell carcino-ma,correlating with poor prognosis of NSCLC patients.The LINC00973 expression was elevated in various NSCLC and chemoresistant cell lines(A549/DDP and A549/5-FU).Overexpression of LINC00973 in A549 and H520 cells markedly enhanced their migration,invasion,and stemness capabilities,while concurrently reducing sensitivity to chemotherapy and targeted therapies.RNA sequencing,along with RT-qPCR results,indicated that ATP-binding cassette transporter G5(ABCG5)was activated in LINC00973-overexpressing A549 and H520 cells.Further database analyses and dual trans-fection experiments confirmed that LINC00973 regulated ABCG5 expression through competitive binding with hsa-miR-150-5p.CONCLUSION:LINC00973,which is aberrantly up-regulated in NSCLC specimens and associated with poor clinical prognosis,promotes the expression of ABCG5 through competitive binding with hsa-miR-150-5p.This interaction leads to en-hanced invasion,stemness,and multidrug resistance in NSCLC cells.
