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.

Background/Aims:
Liver transplantation (LT) following total hepatectomy is a life-saving treatment for hepatocellular carcinoma (HCC). The HCC recurrence after LT hinders the effectiveness of the procedure. The objective of this study is to develop a pre-operative risk stratification model based on a liquid biopsy.
Methods:
We conducted a comprehensive multi-omics study of 260 HCC patients from three centers, including clinical data, low-coverage whole-genome sequencing of cell-free DNA (cfDNA) from plasma, as well as whole-exome, single-nucleus RNA, and spatial transcriptomics from matched tumor and non-tumor tissues.
Results:
We identified cfDNA-derived copy number alteration (CNA) signatures associated with post-transplant recurrence. By integrating cfDNA-derived CNA profiles with single-cell transcriptomic data, we traced recurrence-associated cfDNA to a distinct subpopulation of malignant cells within the primary tumor. These cells were embedded in a pro-metastatic microenvironment of specialized endothelial subtypes and cancer-associated fibroblasts. Notably, most recurrence-associated lesions were detectable in cfDNA prior to liver transplantation (LT). Building on these insights, we developed the ZJU Criteria based on CNA fragments and tumor markers, a pre-LT risk prediction tool that integrates conventional clinical factors with cfDNA-derived CNA signatures, and validated it using internal and independent external cohorts.
Conclusion
Our findings suggest that post-transplant recurrence commonly originates from advanced subclones that emerge late during tumor evolution. The ZJU Criteria provides an accurate, non-invasive strategy that significantly improves pre-LT risk stratification and clinical decision-making for patients with HCC.

Objective To investigate the effects of Xuetong capsule on blood lipids and liver lesion in hyperlipidemic model animals. Methods Sixty ICR mice were randomly divided into six groups. The normal control group was fed with normal diet, the other groups were fed with high-fat diet to induce hyperlipidemia. After four weeks feeding, the three groups were given low, middle, and high doses of Xuetong capsules (0.5, 1.0, and 2.0 g/kg) by gavage, and the positive drug control group was given atorvastatin calcium (1.5 mg/kg) by gavage. The model group was given solvent (0.5% carboxymethyl cellulose sodium). After treatment for 8 weeks, the body weight, organ index, blood lipids, blood glucose and liver function index were measured. The liver oil red staining was used to determine the lipid droplet content, and quantitative PCR was used to detect the expression of inflammatory factors TNF-α, IL-6, and IL-1β. Results The body weight, the weight of liver and spleen were significantly increased by high-fat diet. High-fat diet increased the organ indexes of the liver and spleen, the degree of liver oil red staining, and also significantly increased the levels of glucose, triglyceride (TG), cholesterol (CHOL), and low-density lipoprotein cholesterol (LDL-C) in serum. Compared with the model group, the level of TG has no significant change in low, middle and high doses groups. The level of CHOL in serum was reduced by Xuetong capsule with a dose dependent manner. There were significant difference between the model group and middle, high doses groups. The results of LDL-C were similar, the level of LDL-C was significantly reduced by middle and high doses groups [middle dose (0.55±0.21) mmol/L, high dose (0.52±0.22) mmol/L vs (0.81±0.29) mmol/L in model group, P<0.05]. Compared with the normal control, there was no significant difference in HDL-C levels between the high-fat model and each drug-treated group. Liver function showed that Xuetong capsules significantly reduced the degree of liver oil red staining and decreased the level of alanine aminotransferase (ALT) induced by high-fat diet. The body weight, the weight and organ indexes of liver and spleen were significantly reduced by positive drug control group. The levels of CHOL, LDL-C, and TG, and the degree of liver oil red staining were also significantly reduced in positive drug control group. Further studies have shown that high dose of Xuetong capsules significantly reduced the expression of TNF-α and IL-6 induced by high-fat diet (P<0.05), while the reduction of IL-1β was not so significant (P>0.05). Conclusion Xuetong capsules significantly reduced the body weight of animals with high fat, liver size, fat deposition, inflammatory damage and also significantly reduced blood lipid CHOL and LDL-C levels and transaminase elevation. The above effects may be related to Xuetong capsules reducing the expression of inflammatory factors such as TNF-α and IL-6 in the liver.

ObjectiveThe Golgi apparatus serves as a central hub in the eukaryotic secretory pathway, responsible for the processing, sorting, and trafficking of proteins and lipids. In mammalian cells, the Golgi typically forms a perinuclear ribbon-like structure composed of laterally connected cisternae stacks.The maintenance of Golgi ribbon structure depends on the balance of membrane flux across multiple intracellular trafficking pathways, yet the specific contributions of distinct trafficking branches to Golgi macroscopic morphology remain elusive. In mammalian cells, the Golgi ribbon is typically organized as a perinuclear, laterally connected structure composed of stacked cisternae, and its integrity is highly dynamic and sensitive to perturbations in membrane trafficking. This study aims to elucidate the role of coat protein complex I (COPI)-mediated retrograde transport in maintaining the Golgi ribbon and to dissect the functional relationship between the transmembrane cargo receptors LEPROT/LEPROTL1 (LEPROTs) and the COPI adaptor GOLPH3. MethodsUsing siRNA interference and gene-deficient cell lines, we selectively perturbed COPI- or adaptor protein complex 1 (AP-1)-mediated trafficking pathways in HeLa cells. To quantitatively evaluate Golgi morphology, we employed a “Golgi Angle”-based measurement to assess its circumferential distribution around the nucleus. The spatial distribution of the Golgi ribbon was quantitatively analyzed using confocal microscopy, while Golgi ultrastructure and vesicle density were examined via transmission electron microscopy. Additionally, the subcellular distribution of COPI components was assessed by immunofluorescence co-localization. ResultsSelective inhibition of COPI retrograde transport significantly induced the circumferential extension of the Golgi ribbon around the nucleus, whereas blocking AP-1-mediated anterograde transport resulted in Golgi compaction, indicating opposing roles. These results suggest that different trafficking branches downstream of ARF1 exert distinct and even antagonistic effects on Golgi morphology. LEPROTs-deficient cells exhibited a Golgi extension phenotype highly consistent with COPI impairment. Furthermore, knockdown of GOLPH3 in a LEPROTs double-knockout background produced a significant additive effect on Golgi extension, suggesting that LEPROTs and GOLPH3 play non-redundant roles in regulating COPI-related trafficking processes. Mechanistically, loss of either LEPROTs or GOLPH3 led to the aberrant accumulation of COPI components at endoplasmic reticulum exit sites, accompanied by a reduction in COPI-like vesicles around the Golgi. This redistribution indicates a defect in COPI recycling between the ER-Golgi interface and the Golgi apparatus. Ultrastructural analysis revealed that Golgi cisternae in defective cells became shorter and thicker while maintaining a stable number of stacks. In parallel, the density of Golgi-associated vesicles was markedly decreased, further supporting an impairment in COPI vesicle formation or budding processes. ConclusionThis study demonstrates that active COPI retrograde transport is a critical factor in restricting the over-connection of the Golgi ribbon and maintaining its compactness. Rather than causing fragmentation, partial disruption of COPI function leads to a distinct morphological outcome characterized by Golgi ribbon extension at the light microscopy level and cisternal remodeling at the ultrastructural level. LEPROTs and GOLPH3 cooperatively promote the recycling and vesiculation of COPI components, thereby imposing a structural constraint on the Golgi periphery. Our findings support a model in which multiple adaptor proteins act in parallel to sustain efficient COPI cycling, thereby maintaining Golgi structural homeostasis. These findings provide new cell biological evidence for the membrane trafficking basis of Golgi morphological homeostasis.

To investigate the clinical value of cardiac magnetic resonance feature tracking (CMR-FT) technology in the assessment of the right ventricle function in patients with immune checkpoint inhibitor (ICIs)-related myocarditis. Patients who visited Peking Union Medical College Hospital from April 2022 to April 2024, were diagnosed as ICIs-related myocarditis by cardiologists, and had normal right ventricular ejection fraction (RVEF) were enrolled in myocarditis group. Meanwhile, healthy individuals without cardiovascular diseases were selected as healthy control group. All subjects underwent cardiac magnetic resonance (CMR) examinations. Cardiac function parameters of the left and right ventricles were measured in the subjects, including left ventricular ejection fraction (LVEF), RVEF, left ventricular end-systolic volume index (LVESVI), left ventricular end-diastolic volume index (LVEDVI), right ventricular end-systolic volume index (RVESVI), and right ventricular end-diastolic volume index (RVEDVI). Additionally, myocardial strain of the left and right ventricles were recorded, encompassing left ventricular global longitudinal strain (LV-GLS), left ventricular global circumferential strain (LV-GCS), left ventricular global radial strain (LV-GRS), right ventricular global longitudinal strain (RV-GLS), right ventricular global circumferential strain (RV-GCS), and right ventricular global radial strain (RV-GRS). A total of 30 patients were induded in the myocarditis group and 20 in the healthy control group. The LVEF in the myocarditis group was was lower than that in the control group [(58.0±6.9)% Right ventricular myocardial strain obtained through CMR-FT technology can reveal early right ventricular cardiac dysfunction in patients with ICIs-related myocarditis, providing crucial evidence for early clinical prevention and timely intervention.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.
