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: Disorders of the blood-brain barrier (BBB) arising from diabetes mellitus are closely related to diabetic encephalopathy. Previous research has suggested that neuron-glia antigen 2 (NG2)-glia plays a key role in maintaining the integrity of the BBB. However, the mechanism by which NG2-glia regulates the diabetic BBB remains unclear. Methods: Type 2 diabetes mellitus (T2DM) db/db mice and db/m mice were used. Evans-Blue BBB permeability tests and transmission electron microscopy techniques were applied. Tight junction proteins were assessed by immunofluorescence and transmission electron microscopy. NG2-glia number and signaling pathways were evaluated by immunofluorescence. Detection of matrix metalloproteinase-9 (MMP-9) in serum was performed using enzyme-linked immunosorbent assay (ELISA). Results: In T2DM db/db mice, BBB permeability in the hippocampus significantly increased from 16 weeks of age, and the structure of tight junction proteins changed. The number of NG2-glia in the hippocampus of db/db mice increased around microvessels from 12 weeks of age. Concurrently, the expression of MMP-9 increased in the hippocampus with no change in serum. Sixteen- week-old db/db mice showed activation of the Wnt/β-catenin signaling in hippocampal NG2-glia. Treatment with XAV-939 improved structural and functional changes in the hippocampal BBB and reduced MMP-9 secretion by hippocampal NG2-glia in db/db mice. It was also found that the upregulation of β-catenin protein in NG2-glia in the hippocampus of 16-week-old db/db mice was significantly alleviated by treatment with XAV-939. Conclusion The results indicate that NG2-glia can lead to structural and functional disruption of the diabetic BBB by activating Wnt/β-catenin signaling, upregulating MMP-9, and degrading tight junction proteins.

The surrogate subjects have been gradually replaced from “legal representatives” to “guardians” in China’s relevant norms regarding the surrogate system of the right to informed consent in clinical research recently. Although this change in the expression of surrogate subjects has not altered its legal essence， it may still lead to ambiguities， confusions and deviations， in the understanding of the surrogate subjects for the right to informed consent. Therefore， this paper summarized its characteristics from three aspects， namely， the changes in relevant norms regarding the surrogate system of the right to informed consent in China’s clinical research， their differences from foreign norms， and their differences from surrogate subjects of the medical right to informed consent. On this basis， the formal identity and substantive emphasis between guardians and legal representatives were compared from a normative perspective. Subsequently， the major reasons for legislators to replace the expression of surrogate subjects were explored from three aspects， including institutional systematization， reinforcement of the best interest principle， and cultural values. Finally， corresponding implementation suggestions were proposed for situations where research participants lack guardians during the exercise of the right to informed consent in clinical research.

ObjectiveTo analyze the current status of traditional Chinese medicine （TCM） prediction model research for emerging acute infectious diseases， in order to provide reference for subsequent model construction and optimization. MethodsEight databases， including PubMed， Cochrane Library， and Embase， were systematically searched to comprehensively collect Chinese and English literature on TCM prediction models for emerging acute infectious diseases. The search period ranged from database inception to July 5， 2024. Reporting quality compliance was evaluated using the Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis—Traditional Chinese Medicine （TRIPOD-TCM） guideline. Risk of bias and applicability were assessed using the Prediction Model Risk of Bias Assessment Tool （PROBAST）. ResultsA total of 21 studies were included， comprising 11 early warning model studies， 5 diagnostic model studies， 3 prognostic model studies， and 2 prescription prediction model studies， involving 84 models in total. The diseases involved were mainly viral infectious diseases such as coronavirus disease 2019 （COVID-19） and hepatitis B. The most frequently applied TCM theory was the "five movements and six climates" theory. The most commonly used modeling method was neural network-based approaches. The most frequently reported predictive factors were meteorological variables， including daily mean temperature， wind speed， precipitation， relative humidity， and vapor pressure. In terms of reporting quality， the included studies showed poor item-level compliance， with only 13 sub-items achieving compliance rates above 50%. Overall compliance ranged from 27% to 59% across studies. Although the included studies showed relatively good applicability， all were assessed as having a high risk of bias. The main sources of bias included inappropriate handling of missing data， absence of calibration methods， and unreasonable validation strategies， indicating deficiencies across multiple stages of model development. ConclusionCurrent research on TCM prediction models for emerging acute infectious diseases exhibits distinctive modeling characteristics. These models are based on traditional TCM theories such as the "five movements and six climates"， incorporate TCM-specific features as predictive variables， and use TCM syndromes as outcomes. However， they generally suffer from low reporting compliance and a high risk of bias. Future studies should systematically design model development and validation processes， adhere to TRIPOD-TCM reporting standards， and apply PROBAST or develop dedicated bias risk assessment tools for TCM prediction models to improve methodological quality and promote their translation into clinical practice.

ObjectiveTo observe the effect of Huayu Mingmu prescription on retinal angiogenesis and phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）-hypoxia inducible factor-1α/vascular endothelial growth factor A （HIF-1α/VEGFA） signaling pathway in diabetic retinopathy （DR） rats. MethodsSixty-four SPF-grade male SD rats were used in the study. Eleven rats were randomly selected as the normal group， while the remaining 53 rats were fed a high-sugar， high-fat diet combined with low-dose streptozotocin （STZ） intraperitoneal injection to establish a type 2 diabetes mellitus （T2DM） rat model. DR model evaluation was performed after 12 weeks of diabetes. The rats were then divided into model， low-dose， medium-dose， and high-dose groups of Huayu Mingmu prescription （9.29， 18.57， 37.14 g·kg^-1）， and a calcium dobesilate group （0.16 g·kg^-1）， with 10 rats in each group. The rats were orally administered the corresponding doses of Huayu Mingmu prescription and calcium dobesilate. The normal and model groups received equal volumes of physiological saline via gavage for 8 consecutive weeks. Retinal vascular changes were observed through fundus photography， and pathological changes in retinal tissue were evaluated using hematoxylin-eosin （HE） staining. Retinal microvascular pathological changes were examined through retinal vascular network preparation and periodic acid-Schiff （PAS） staining. Immunofluorescence （IF） was used to detect the expression of VEGFA and angiopoietin-2 （Ang-2） in retinal tissue. Western blot was employed to detect the protein expression of PI3K， Akt， mTOR， HIF-1α， VEGFA， and VEGFR2 in retinal tissue. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to assess the mRNA expression of PI3K， Akt， mTOR， HIF-1α， VEGFA， and VEGFR2 in retinal tissue. ResultsCompared with the normal group， the model group exhibited significant pathological changes in retinal tissue， including the appearance of acellular capillaries， as well as significant endothelial cell （E） proliferation and pericyte （P） loss （P<0.01）. The E/P was significantly elevated （P<0.01）. Protein and mRNA expression levels of PI3K， Akt， mTOR， HIF-1α， VEGFA， and VEGFR2 in retinal tissue were significantly increased （P<0.01）， and the expression of Ang-2 protein was significantly elevated （P<0.01）. In contrast， retinal tissue in the treatment groups showed alleviated pathological changes， with reduced endothelial cell proliferation and pericyte loss （P<0.05， P<0.01）. Among the treatment groups， the high-dose Huayu Mingmu prescription and the calcium dobesilate group exhibited a decreased E/P （P<0.01）. Protein and mRNA expression levels of PI3K， Akt， mTOR， HIF-1α， VEGFA， and VEGFR2 in retinal tissue were significantly reduced （P<0.05， P<0.01）， and the expression of Ang-2 protein was significantly decreased （P<0.01）. ConclusionHuayu Mingmu prescription can intervene in retinal neovascularization in DR rats， delay the progression of DR， and its mechanism may be related to antagonizing the PI3K/Akt/mTOR-HIF-1α/VEGFA signaling pathway.

AIM To investigate the protective effect of Sanfeng Tongqiao Dropping Pills against house dust mite(HDM)-induced allergic asthma in mice.METHODS Compared to the intact BALB/c mice in the blank control group,the BALB/c mice randomly assigned into the model group,the dexamethasone group(0.67 mg/kg),and the low-dose,medium-dose,and high-dose Sanfeng Tongqiao Dropping Pills groups(15,30 and 60 mg/kg),were induced into acute allergic asthma models via weekly intraperitoneal sensitization with 0.1 mL HDM solution(0.5 mg/mL)for three weeks followed by three consecutive daily intranasal challenges with 10 μL HDM solution(2.5 mg/mL)starting in the third week.The drug administered continuously 7 days after the last excitation.The mice had their airway reactive Penh value detected,their pulmonary pathological changes observed by HE staining,their blood eosinophils(EOS)counted,their Th2 cytokines in lung tissue and serum IgE levels detected by ELISA,and their number of peripheral blood mononuclear cells(PBMC)and pulmonary Th2 cells detected by flow cytometry.Chronic allergic asthma was induced in grouped BALB/c mice through repeated intranasal challenges with 10 μL HDM solution(2.5 mg/mL)administered five times weekly for five consecutive weeks.Drug treatment continued for 14 days following the final challenge.After the final treatment,the mice had their pulmonary pathological changes observed by HE staining,and their levels of Th2 cytokines in B ALF and lung tissue and serum IgE detected by ELISA.RESULTS Compared to the blank control group,the acute allergic asthma model group exhibited increases in Penh value,EOS count and IgE level in serum,IL-4 and IL-5 levels in lung tissue(P＜0.01);obvious pulmonary inflammatory cells infiltration,and thickened airway wall;and increase in pulmonary number of Th2 cells(P＜0.01).Compared to the model group,the groups intervened with Sanfeng Tongqiao Dropping Pills demonstrated decreased Penh value,serum EOS count,IgE level and IL-5 level in lung tissue(P＜0.05,P＜0.01);reduced pulmonary inflammatory infiltration and alleviated airway wall thickening;and decreased number of pulmonary Th2 cells.Compared to the blank group,the chronic allergic asthma model group showed obvious pulmonary inflammatory infiltration and airway wall thickening;and increased EOS count and IgE level in serum,IL-4 and IL-13 in lung tissue and IL-14 in BALF(P＜0.05,P＜0.01).Compared to the model group,the groups intervened with either medium-dose or high-dose Sanfeng Tongqiao Dropping Pills demonstrated reduced pulmonary inflammatory infiltration;and decreased serum EOS count,IgE level,IL-13 in lung tissue and IL-14 in BALF(P＜0.05,P＜0.01).CONCLUSION Sanfeng Tongqiao Dropping Pills reduce Th2 cells in peripheral blood and lung tissue,suppress type 2 inflammation,and thereby alleviate allergic asthma.

There is significant inter-individual variation of pharmacokinetics and pharmacody-namics in patients receiving tacrolimus(TAC)for an-ti-rejection therapy,which cause the rejection or toxic action.Based on results of therapeutic drug monitoring and pathophysiological index of trans-plant patients,the individualized dosing regimen can be designed and adjusted by using model in-formed precision dosing(MIPD).The patients'clini-cal outcome can be improved.In the consensus,the different methods of MIPD used for patients re-ceived TAC for anti-rejection therapy were intro-duced,which can be used for the designing and ad-justing doing regimen,predicting adverse drug reac-tion,improving medication adherence and econom-ics during therapy.

AIM:This study aims to investigate the protective effect of Buyang-Huanwu decoction(BYHWD)on cerebral ischemia-reperfusion injury(CIRI)in rats,focusing on its role in regulating the autophagy of cerebral micro-vascular endothelial cells(BMECs).METHODS:(1)We established a rat model of middle cerebral artery occlusion/re-perfusion(MCAO/R)and divided the subjects into four groups:sham group,model(MCAO/R)group,BYHWD group,and 3-n-butylphthalide(NBP)group.Neurological deficits were assessed using the Zea Longa score,while the volume of cerebral infarction was measured through 2,3,5-triphenyltetrazolium chloride(TTC)staining.Pathological damage in the ischemic penumbra was evaluated using HE staining,and blood-brain barrier(BBB)permeability was assessed by Evans blue(EB)staining.The ultrastructure of BMECs was analyzed by transmission electron microscopy,and the co-expres-sion and positive cell rate of microtubule-associated protein 1 light chain 3(LC3)in BMECs were determined through im-munofluorescence double staining.Additionally,the protein expression levels of ZO-1,claudin-5 and occludin in the cor-tical region of the ischemic penumbra in rats were examined using Western blot analysis.(2)A rat BMEC model of oxy-gen-glucose deprivation/reoxygenation(OGD/R)was also established.Rat BMECs were categorized into normal control(CON),OGD/R,dimethyl sulfoxide(DMSO),rapamycin and 3-methyladenine groups to observe autophagy levels by monodansylcadaverine(MDC)staining.Furthermore,rat BMECs were divided into CON,OGD/R,BYHWD-containing serum(BHDS)and NBP groups.The cell autophagy was assessed by MDC staining and Western blot,while cell viability was measured by CCK-8 assay.RESULTS:(1)The rats in MCAO/R group exhibited significantly higher neurological scores(P＜0.01)and increased cerebral infarction volumes(P＜0.01)compared with sham group.Severe damage in the ischemic penumbra was observed,characterized by disordered tissue structure,widened intercellular spaces,and compro-mised cellular integrity.The EB dye permeability was notably elevated(P＜0.01),and BMECs showed structural destruc-tion,including damaged cell membranes,swollen Golgi apparatus,dilated endoplasmic reticulum vesicles,and damaged mitochondria.The ratio of LC3+CD31+/CD31+and the protein levels of ZO-1,claudin-5 and occludin were significantly el-evated(P＜0.01).In contrast,the rats in BYHWD and NBP groups demonstrated lower neurological scores(P＜0.01)and reduced cerebral infarction volumes(P＜0.01).Furthermore,EB permeability decreased(P＜0.01),BMEC morphol-ogy improved,and the protein expression levels of ZO-1,claudin-5 and occludin increased(P＜0.05).(2)Rat BMECs in OGD/R group had a significantly elevated autophagy level compared with CON group(P＜0.01),with increased expres-sion of LC3 and beclin-1 proteins and decreased level of P62 protein(P＜0.05).Notably,the cells in BHDS and NBP groups displayed decreased autophagy level compared with OGD/R group,with increased cell viability(P＜0.01),re-duced LC3 and beclin-1 protein expression,and increased P62 protein expression(P＜0.05).CONCLUSION:Buyang-Huanwu decoction alleviates cerebral ischemia-reperfusion injury in rats by inhibiting the autophagy of cerebral microvas-cular endothelial cells.
