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.

OBJECTIVE To provide standardized guidance for the rational clinical use of antibody-based drugs for the treatment of myasthenia gravis， and to enhance the evidence-based system of guidelines and consensus in this field. METHODS The consensus expert team consisted of 71 multidisciplinary experts from 28 provinces/autonomous regions/municipalities directly under the Central Government. Evidence was systematically retrieved through multiple databases， drug package inserts， and official websites of international and national health administrative authorities， drug regulatory agencies， healthcare security departments， and related industry associations， up to April 30， 2025. Evidence was graded according to the 2014 version of JBI pre-grading system for evidence from intervention studies. Based on full consideration of the current best evidence and multidisciplinary expert experience， the expert consensus recommendations were formulated using a modified Delphi method. RESULTS The Evidence-based expert consensus on the clinical application and pharmaceutical management of antibody-based drugs for the treatment of myasthenia gravis standardized the key points of whole-process pharmaceutical management for four antibody-based drugs approved for marketing in the mainland of China for the treatment of myasthenia gravis （efgartigimod alfa， efgartigimod alfa/hyaluronidase， eculizumab， and rozanolixizumab）. It formulated 37 expert consensus recommendations covering nine pharmaceutical management aspects： drug suitability selection， medication in special populations， administration methods， drug storage， therapeutic drug monitoring and pharmacogenetic testing， immunization management， drug interactions， pharmaceutical care， and off-label drug use. CONCLUSIONS Based on the current best evidence and multidisciplinary expert experience， this consensus establishes a whole-process management framework for antibody-based drugs for the treatment of myasthenia gravis， from clinical application to pharmaceutical management. It provides a scientific basis for the rational and precise use of these drugs in clinical practice， effectively promotes the enhancement of pharmaceutical management efficiency， and helps improve the overall therapeutic benefits for patients.

OBJECTIVE To construct a research question system of the Guideline for the Management of Therapeutic Drug Monitoring （hereinafter referred to as the Guideline ）， so as to provide the basis for the formulation of the Guideline . METHODS Based on literature research and expert interviews， the questionnaire about research questions of the Guideline was initially constructed. Through the modified Delphi method， the online questionnaire survey and expert consensus meeting were conducted among the Guideline development experts to determine the research question system of the Guideline . RESULTS A total of 59 questionnaires were distributed， and 52 valid questionnaires were collected. The positive coefficient of experts was 88.14%. The experts came from 21 provinces/autonomous regions/municipalities directly under the central government， covering multidisciplinary experts related to therapeutic drug monitoring， all of whom held senior professional titles. After one round of survey， a consensus was reached on the research questions， and a research question framework encompassing four research parts was constructed， including： indications for conducting therapeutic drug monitoring （4 first-level research questions，10 second-level research questions， 31 third-level research questions）； therapeutic drug monitoring technical process （3 first-level research questions， 9 second-level research questions， 13 third-level research questions）； result interpretation and clinical application （3 first-level research questions and 3 second-level research questions）； quality control （8 first-level research questions and 12 second-level research questions）. The importance scores for the four parts ranged from 4.71 to 4.88， with full-score rates all no less than 73.08%. The expert authori ty coefficients were all no less than 0.90， the coefficients of variation of importance scores were all no higher than 0.11， and Kendall’s W ranged from 0.464 to 0.626 （all P ＜0.05）. CONCLUSIONS The constructed research question system has high authority， scientificity， and reliability， laying a foundation for the standardized formulation of the Guideline .

Kynurenine pathway (KP) is a major catabolic route of tryptophan, generating a series of bioactive metabolites including kynurenine, kynurenic acid (KA), quinolinic acid, and 3-hydroxykynurenine. Beyond its fundamental role in amino acid metabolism, KP exerts critical regulatory functions in neurodevelopment, synaptic plasticity, and immune modulation. Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental condition with onset in early childhood, characterized by persistent deficits in social communication and restricted, repetitive behaviors. Despite extensive research, the etiological mechanisms underlying ASD remain highly complex and incompletely understood, involving genetic, environmental, and immunological factors. Emerging clinical evidence has consistently revealed a significant imbalance in KP metabolites in individuals with ASD, often accompanied by altered ratios of neuroprotective versus neurotoxic byproducts. However, the primary drivers of this metabolic dysregulation and its causative contribution to ASD pathogenesis are not yet fully elucidated. In this review, we systematically review the enzymatic steps of KP and the principal physiological functions of its major metabolites, with particular emphasis on their dual roles in neuroprotection and neurotoxicity. We then analyze the potential pathogenic mechanisms through which KP dysfunction may contribute to ASD, focusing on two interconnected etiological dimensions. First, KP imbalance can promote oxidative stress, which in turn triggers chronic inflammatory responses via microglial activation and release of pro-inflammatory cytokines, thereby disrupting neuronal homeostasis. Second, aberrant KP metabolism affects neurotransmitter systems, particularly glutamatergic and dopaminergic signaling, leading to impaired neural circuit development and synaptic pruning. By integrating current findings on the KP-ASD association, this review offers a comprehensive etiological framework and a clinically relevant paradigm. Furthermore, we highlight that specific KP metabolites, such as the KA/quinolinic acid ratio, hold promise as peripheral biomarkers for early diagnosis and disease stratification. Finally, we discuss the therapeutic potential of targeting KP enzymes or receptors for personalized intervention strategies, while acknowledging the challenges in translating these findings into clinical practice.

"Weibing" is a fundamental concept in traditional Chinese medicine (TCM), representing a transitional state characterized by diminished self-regulatory abilities without overt physiological or social dysfunction. This perspective delves into the biological foundations and quantifiable markers of Weibing, aiming to establish a research framework for early disease intervention. Here, we propose the "Health Quadrant Classification" system, which divides the state of human body into health, sub-health, disease-susceptible state, and disease. We suggest the disease-susceptible stage emerges as a pivotal point for TCM interventions. To understand the intrinsic dynamics of this state, we propose laboratory and clinical studies utilizing time-series experiments and stress-induced disease susceptibility models. At the molecular level, bio-omics technologies and bioinformatics approaches are highlighted for uncovering intricate changes during disease progression. Furthermore, we discuss the application of mathematical models and artificial intelligence in developing early warning systems to anticipate and avert the transition from health to disease. This approach resonates with TCM's preventive philosophy, emphasizing proactive health maintenance and disease prevention. Ultimately, our perspective underscores the significance of integrating modern scientific methodologies with TCM principles to propel Weibing research and early intervention strategies forward.

In order to standardize the workflow for the clinical comprehensive evaluation of drugs， enhance the assessment of research evidence， and improve the application value of research outcomes in translational practice， the Chinese Pharmaceutical Association issued the Guideline for the Workflow of Clinical Comprehensive Evaluation of Drugs （T/CLPA 5-2025） in June 2025. The core points include clarifying the concept of clinical comprehensive evaluation of drugs and standardizing the main work processes and technical essentials. This article provides a detailed interpretation of the technical methods for standard formulation， the operational logic of the four core processes （theme selection， evaluation implementation， evidence evaluation， result application transformation）， and the key points of core technologies. The aim is to assist medical institution technicians， policymakers and researchers in accurately grasping the connotation of the standards， resolving practical concerns such as process connection and technology application， and enhancing the quality and homogenization of evaluation work. It provides support for the scientific decision-making of healthcare and health， and the rational clinical medication.

Accurate timing of myelination is crucial for the proper functioning of the central nervous system. Here, we identified a de novo heterozygous mutation in TMEM63A (c.1894G>A; p. Ala632Thr) in a 7-year-old boy exhibiting hypomyelination. A Ca²⁺ influx assay suggested that this is a loss-of-function mutation. To explore how TMEM63A deficiency causes hypomyelination, we generated Tmem63a knockout mice. Genetic deletion of TMEM63A resulted in hypomyelination at postnatal day 14 (P14) arising from impaired differentiation of oligodendrocyte precursor cells (OPCs). Notably, the myelin dysplasia was transient, returning to normal levels by P28. Primary cultures of Tmem63a^-/- OPCs presented delayed differentiation. Lentivirus-based expression of TMEM63A but not TMEM63A_A632T rescued the differentiation of Tmem63a^-/- OPCs in vitro and myelination in Tmem63a^-/- mice. These data thus support the conclusion that the mutation in TMEM63A is the pathogenesis of the hypomyelination in the patient. Our study further demonstrated that TMEM63A-mediated Ca²⁺ influx plays critical roles in the early development of myelin and oligodendrocyte differentiation.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

OBJECTIVE To construct the research questions and topic selection evaluation index system of the Guideline for Topic Selection for Comprehensive Clinical Evaluation of Drugs （hereinafter referred to as the Guideline）， so as to provide the basis for the formulation of the Guideline. METHODS Through literature research， an expert questionnaire on the research questions and evaluation index system of the Guideline was initially constructed. Experts were selected according to relevant requirements of the guideline formulation and Delphi method； the research questions and evaluation indicators of the Guideline were screened by electronic questionnaire communication， and the weights of evaluation index system of topic selection were assigned by the analytic hierarchy process. RESULTS Five research questions of the Guideline were constructed， including the organization and management of theme selection， evaluation process， evaluation methods， evaluation index system， and index weight assignment. And a theme selection and evaluation index system， including 5 primary indexes， 9 secondary indexes and 17 tertiary indexes， was constructed. Kendall coefficients of the research questions and all indexes were ＞0.4， and the P values of χ2 test were＜0.05， which meant the evaluation results were consistent. The weights of all levels of the evaluation index system were assigned by analytic hierarchy process with consistency ratio of 0.007 6 （＜0.1）， and the model matrix passed the consistency test. CONCLUSIONS The research questions and topic selection evaluation index system of the Guideline established in this study are highly authoritative， scientific and reliable， which lay a foundation for the standardization of the Guideline.
