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 prepare pullulan-spermine (PS)-poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) conjugated with CD3 antibody, and to investigate their effects on T cell proliferation and cytokine secretion.Methods:Purulan polysaccharide was sperminized to synthesize PS, hydrophobically modified, and then grafted with PLGA to synthesize PS-PLGA. Infrared spectroscopy and nuclear magnetic resonance hydrogen spectrum were used to characterize the structure of PS-PLGA. PS-PLGA NPs were prepared by ultrasonic dialysis method and then coupled with CD3 antibody to prepare PS-PLGA-CD3 NPs. The morphological features of PS-PLGA-CD3 NPs were observed by the transmission electron microscope. The particle sizes, Zeta potential and dispersive coefficient of the NPs were measured using the dynamic laser particle size analyzer. The amount of coupled CD3 antibody on the surface of the NPs was determined using quantitative fluorescence analysis method. The effects of 1, 10, 50, 100, and 200 μg/ml PS-PLGA-CD3 NPs on T-cell proliferation were determined using cell counting kit-8 method. The effects of 1, 10, 50, 100, 200 μg/ml PS-PLGA-CD3 NPs on secretion of interferon-γ (IFN-γ), interleukin-2 (IL-2), and tumor necrosis factor-β (TNF-β) by T cell were determined by enzyme-linked immunosorbent assay. Comparisons were made using independent sample t-test or one-factor analysis of variance. Results:Pullulan and PS showed strong absorption at 2 939 cm ?1, and PS had a weaker absorption peak at 3 384 cm ?1 than pullulan. The proton peaks of spermine appeared at chemical shifts of 1.25 to 1.50, 1.63, and 2.25 to 2.75. The characteristic peaks of PLGA appeared at chemical shifts of 1.50, 3.40, and 4.80 to 5.30. Compared to pullulan, the characteristic peaks of both PS and PLGA appeared in the corresponding intervals for PS-PLGA. The morphology of PS-PLGA-CD3 NPs with spermine substitution at 9.7% was all regular and circular, with a mean particle size of (173.3±24.5) nm, a Zeta potential of (?12.78±3.68) mV, the dispersive coefficient of 0.254±0.101, and the CD3 antibody mass fraction of (52.1±9.4) μg/mg. The differences in cell survival were statistically significant for PS-PLGA-CD3 NPs and PS-PLGA NPs, respectively, after co-incubation with T cell after 24, 48, and 72 h at concentrations of 50, 100, and 200 μg/ml, respectively (all P<0.05). The results of the three concentration comparisons after 24 h of co-incubation were [(129.8±23.1)% vs (95.5±8.9)%, (137.5±22.7)% vs (95.1±15.8)%, and (142.3±25.6)% vs (93.2±9.2)%]; and the results after 48 h were [(145.9±23.7)% vs (95.8±10.6)%, (149.3±23.5)% vs (94.9±16.3)%, and (161.2±26.9)% vs (91.5±8.3)%]; and the results after 72 h were [(147.6±20.1)% vs (95.9±17.8)%, (152.4±22.3)% vs (92.7±16.5)%, and (167.7±25.4)% vs (90.8±17.4)%]. The differences in the levels of IFN-γ, IL-2 and TNF-β were statistically significant (all P<0.05 or 0.01) at 50, 100 and 200 μg/ml concentrations for PS-PLGA-CD3 NPs and PS-PLGA NPs, respectively. For IFN-γ, the results of the comparison of the three concentrations were [(35.7±3.1) ng/ml vs (16.4±6.9) ng/ml, (67.3±5.2) ng/ml vs (19.6±2.8) ng/ml, and (79.0±4.2) ng/ml vs (19.3±2.3) ng/ml]; and for IL-2, the results were [(43.5±8.2) ng/ml vs (12.6±1.9) ng/ml, (53.5±7.8) ng/ml vs (15.8±3.3) ng/ml, and (64.0±8.2) ng/ml vs (17.4±3.8) ng/ml]; and for TNF-β, the results were [(108.4±18.9) pg/ml vs (40.8±1.3) pg/ml, (152.3±28.3) pg/ml vs (56.4±3.7) pg/ml and (185.0±33.6) pg/ml vs (81.6±10.2) pg/ml]. Conclusions:PS-PLGA-CD3 NPs are successfully prepared, which have the function of effectively promoting T cell proliferation and cytokine sectetion.

Objective: To explore the association between dietary inflammatory index (DII) and metabolic syndrome (MetS) and its components among children aged 6-14 years in Beijing, so as to provide a reference for preventing MetS. Methods: A cross sectional study was carried out in 2 086 records of 1 832 children from the 2017 and 2019 Nutrition and Health Surveillance in Primary and Secondary school students of Beijing (NHSPSB). Three day consecutive 24 hour dietary recalls combined with weighing household cooking oils and condiments were used to collect dietary intake and calculate DII. MetS was diagnosed according to "Definition and Suggestion on the Metabolic Syndrome of Chinese Children and Adolescent". The Generalized estimating equations (GEEs) models were used to analyze the association between DII and the presence of MetS and its components (abdominal obesity, high triglyceride, low high density lipoprotein cholesterol, hypertension, and hyperglycemia). Results: The mean DII score was (1.64±1.07) for the included children. No significant association was found between DII scores and the likelihood of MetS (per 1 point increment: OR =1.16, 95% CI =0.92-1.48, P >0.05). In terms of the components of MetS, DII scores were positively associated with the odds of high triglyceride (per 1 point increment: OR =1.17, 95% CI =1.01-1.36, P <0.05). There was no statistically significant difference in the association among different age groups ( P >0.05). No significant associations were observed between DII and other MetS components( P >0.05). Conclusion DII scores may not be correlated with the risk of MetS, but proinflammatory diet might increase the risk of high triglyceride. DII score in childhood should be emphasized to identify and prevent MetS as soon as possible.

This consensus report provides a brief account of the concept, methodology and implementation of MIPD as well as clinical decision supporting systems for MIPD. The status and future advancing of MIPD was also discussed to facilitate the appropriate application and development of MIPD in China.

Objective:To observe the presence or absence of necroptosis in PC12 cells after radiation injury, and to detect the expression of receptor-interacting protein 3(RIP3) and evaluate its regulatory effect on necroptosis.Methods:PC12 cells were treated with different doses of irradiation and their necroptosis was detected by lactate dehydrogenase (LDH) release at different time points. After pretreatment with necroptosis inhibitor Necrostatin-1(Nec-1), the changes of cell necroptosis were detected by LDH. The expression level of RIP3 after irradiation intervention was detected by Western blot (WB). After pretreatment with the RIP3-specific inhibitor GSK′872, the changes of cell necroptosis were detected by LDH. The best transfection sequence of RIP3 knockout was screened by WB. The cells were divided into the control group, irradiation group, solvent control group, no-load control group and pretreatment group. WB, immunofluorescence staining, MTT, LDH and Annex V-fluorescein Isothiocyanate/Propidium Iodide (AnnexV-FITC/PI) flow cytometry were used for detection and analysis.Results:After 4 Gy irradiation, the degree of cell necrosis was the highest after 3 hours of culture, and the expression level of RIP3 protein was up-regulated. The cell necrosis was decreased after Nec-1, GSK′872 and RIP3 gene knockdown pretreatment.Conclusions:The radiation injury of 4 Gy can induce the necroptosis of PC12 cells, and the most significant effect can be observed when cultured for 3 hours after irradiation. RIP3 is involved in the process of necroptosis of PC12 cells induced by radiation injury, and plays a pivotal positive regulatory role.

A splicing mutation in VPS4B can cause dentin dysplasia type I (DD-I), a hereditary autosomal-dominant disorder characterized by rootless teeth, the etiology of which is genetically heterogeneous. In our study, dental follicle cells (DFCs) were isolated and cultured from a patient with DD-I and compared with those from an age-matched, healthy control. In a previous study, this DD-I patient was confirmed to have a loss-of-function splicing mutation in VPS4B (IVS7 + 46C > G). The results from this study showed that the isolated DFCs were vimentin-positive and CK14-negative, indicating that the isolated cells were derived from the mesenchyme. DFCs harboring the VPS4B mutation had a significantly higher proliferation rate from day 3 to day 8 than control DFCs, indicating that VPS4B is involved in cell proliferation. The cells were then replenished with osteogenic medium to investigate how the VPS4B mutation affected osteogenic differentiation. Induction of osteogenesis, detected by alizarin red and alkaline phosphatase staining in vitro, was decreased in the DFCs from the DD-I patient compared to the control DFCs. Furthermore, we also found that the VPS4B mutation in the DD-I patient downregulated the expression of osteoblast-related genes, such as ALP, BSP, OCN, RUNX2, and their encoded proteins. These outcomes confirmed that the DD-I-associated VPS4B mutation could decrease the capacity of DFCs to differentiate during the mineralization process and may also impair physiological root formation and bone remodeling. This might provide valuable insights and implications for exploring the pathological mechanisms underlying DD-I root development.
