The inflammatory microenvironment is closely associated with the initiation and progression of osteoarthritis （OA）， specifically manifesting as macrophage activation， dysregulation of inflammatory cytokines， and redox imbalance. Following an overview of the pathological characteristics of the OA inflammatory microenvironment， this paper reviews the research progress on the mechanism of traditional Chinese medicine （TCM） intervening in OA by modulating the inflammatory microenvironment. It has been found that TCM monomers/active ingredients （such as total alkaloids from Strychnos nux-vomica ， quercetin， triptolide， etc.）， herb pairs （e.g. Angelica pubescens - Gentiana macrophylla ， Carthami Flos-Lycopodii Herba）， and TCM formulas （such as Zhuanggu jianxi formula， Duhuo jisheng decoction and Rongjin niantong formula， etc.） can inhibit macrophage activation， reduce the release of proinflammatory cytokines and the generation of reactive oxygen species by inhibiting multiple signaling pathways， including nuclear factor-κB， Wnt/ β -catenin， and mitogen-activated protein kinase， thereby alleviating the articular inflammatory microenvironment， restoring local joint homeostasis， and slowing the progression of OA.

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 explore the application value of computed tomography (CT) three-dimensional reconstruction in total knee arthroplasty (TKA). Methods A total of 102 patients who underwent TKA in our hospital between April 2022 and April 2025 were enrolled and divided using a random number table into a traditional group (51 cases, routine preoperative evaluation) and a study group (51 cases, CT three-dimensional reconstruction-assisted surgery). The therapeutic efficacy at 3 months postoperatively and perioperative indicators were compared between the two groups. The hip-knee-ankle (HKA) angle was measured preoperatively and at 3 months postoperatively. The Hospital for Special Surgery (HSS) knee score and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score were recorded preoperatively and at 3 and 6 months postoperatively. Complications were documented. Results The excellent/good rate in the study group (92.16%) was higher than that in the traditional group (74.51%) (P<0.05). The operation time, intraoperative blood loss, postoperative drainage volume, and hospital stay in the study group were (69.52 ± 7.11) min, (102.69 ± 8.54) mL, (167.33 ± 12.35) mL, and (10.93 ± 2.37) days, respectively, which were shorter than those in the traditional group [(78.45 ± 5.98) min, (108.36 ± 10.02) mL, (175.96 ± 14.93) mL, and (12.04 ± 1.95) days] (P<0.05). At 3 months postoperatively, the HKA angle was 178.02° ± 1.05° in the study group and 177.45° ± 1.34° in the traditional group, both were significantly improved compared with those before operation, with the study group showing better improvement (P<0.05). The HSS knee and WOMAC scores in both groups at 3 and 6 months postoperatively were improved compared with preoperative scores (P<0.05). At 3 and 6 months postoperatively, the study group showed higher HSS knee score and lower WOMAC score than the traditional group (P<0.05). The incidence of complications in the study group (3.92%) was lower than that in the traditional group (17.65%) (P<0.05). Conclusion TKA guided by CT three-dimensional reconstruction improved the excellent/good rate, optimized HKA angle and knee function, shortened operation time and hospital stay, reduced intraoperative blood loss and postoperative drainage volume, and decreased the incidence of complications.

As people’s attention to health continues to increase, the market demand for traditional Chinese medicine (TCM) is growing steadily. The quality and safety of Chinese medicinal materials have attracted unprecedented social attention. In particular, the issue of exogenous harmful residue pollution in TCM has become a hot topic of concern for both regulatory authorities and society. The Chinese Pharmacopoeia 2025 Edition further refines the detection methods and limit standards for exogenous harmful residues in TCM. This not only reflects China’s high-level emphasis on the quality and safety of TCM but also demonstrates the continuous progress made by China in the field of TCM safety supervision. Basis on this study, by systematically reviewing the development history of the detection standards for exogenous harmful residues in TCM and analyzing the revisions and updates of these detection standards in the Chinese Pharmacopoeia 2025 Edition, deeply explores the key points of the changes in the monitoring standards for exogenous harmful residues in TCM in the Chinese Pharmacopoeia 2025 Edition. Moreover, it interprets the future development directions of the detection of exogenous residues in TCM, aiming to provide a reference for the formulation of TCM safety supervision policies.

Objective To investigate the mechanism of serine protease inhibitor A3N(SerpinA3N)in alleviating reti-nal neural injury in diabetic mice by inhibiting Müller cell inflammation.Methods Thirty-six db/db mice(72 eyes)were randomly divided into the db/db group,the db/db+SerpinA3N-overexpressing adeno-associated virus(AAV-SerpinA3N)group,and the db/db+empty vector adeno-associated virus(NC-SerpinA3N)group,with 12 mice in each group.Twelve age-matched healthy male littermate mice were randomly selected as the healthy control group(db/m group).Mice in each group were sacrificed 4 weeks after the corresponding treatments.Immunofluorescence staining was used to detect the co-localization of SerpinA3N and glial fibrillary acidic protein(GFAP)in the mouse retina.Hematoxylin-eosin(HE)staining was used to observe histopathological changes in the retinal tissue.TUNEL staining was used to detect the apoptosis of reti-nal ganglion cells(RGCs).Immunohistochemistry was used to detect GFAP expression.ELISA was used to measure the levels of inflammatory factors[interleukin(IL)-1 β,IL-6,IL-18,and tumor necrosis factor-α(TNF-α)]in the retinal tis-sue.The predicted target genes of SerpinA3N were imported into the STRING database to construct a protein-protein inter-action(PPI)network.The highest-scoring target was selected based on the scores for molecular docking.Western blot was used to detect the expression levels of SerpinA3N,nuclear factor kappa B(NF-κB),and spleen focus-forming virus proviral integration oncogene(Spi1)proteins in the retinal tissue.Results Immunofluorescence staining showed co-lo-calized expression of SerpinA3N and GFAP in the retinal tissue.Compared with the db/m group,the db/db,db/db+NC-SerpinA3N,and db/db+AAV-SerpinA3N groups showed decreased retinal thickness and RGC count,and increased number of TUNEL-positive cells,relative GFAP-positive expression intensity,levels of all inflammatory factors,and expression lev-els of NF-κB and Spi1 proteins,while SerpinA3N protein expression was decreased(all P＜0.05).Compared with the db/db group,the db/db+AAV-SerpinA3N group showed increased retinal thickness and RGC count,and decreased number of TUNEL-positive cells,relative GFAP-positive expression intensity,levels of all inflammatory factors,and expression levels of NF-κB and Spi1 proteins,while SerpinA3N protein expression was increased(all P＜0.05).Compared with the db/db+AAV-SerpinA3N group,the db/db+NC-SerpinA3N group showed decreased retinal thickness and RGC count,and increased number of TUNEL-positive cells,relative GFAP-positive expression intensity,levels of all inflammatory factors,and ex-pression levels of NF-κB and Spi1 proteins,while SerpinA3N protein expression was decreased(all P＜0.05).The PPI re-sults indicated an interaction between SerpinA3N and Spi1.Molecular docking results showed that Spi1 could form hydro-gen bonds with residues surrounding SerpinA3N.Conclusion Overexpression of SerpinA3N can inhibit Müller cell in-flammation and ameliorate retinal neural injury in diabetic mice,and the mechanism may be associated with the inhibition of the Spi1/NF-κB signaling pathway.

Objective To propose a lead attention network-based ST-T change recognition algorithm to detect ECG ST-T changes accurately.Methods Firstly,heartbeat signals were extracted through R-wave localization,and a 12-lead heartbeat matrix was generated by correlation-based screening and merging to realize data augmentation.Secondly,a lead attention module was constructed by combining depthwise convolution(DWConv)with the channel attention squeeze-and-excitation block(SE-block)structure to perceive the differences in ST-T status among electrocardiogram leads.Thirdly,the mapping output by two independent attention modules was fused and splicing with the original signal residual was carried out,so that attention information extraction and original information transfer were enhanced effectively.Finally,SE-ResNet was used as the backbone network to extract signal features to complete the classification and identification of ST-T changes.To validate the recognition performance of the proposed algorithm for ST-T changes in ECG,the 12-lead ECG data of 97 472 patients containing different ECG rhythms were collected for ablation and comparison experiments at the First Affiliated Hospital of Army Medical University.Results The proposed algorithm achieved an AUC of 0.965 with a sensitivity of 90.51%,specificity of 90.23%,positive predictive value of 89.24%and overall accuracy of 90.36%on an independent test set.Comparative analysis demonstrated superior performance to four benchmark architectures,including VGG16,ResNet18,MobileNetV3-Small and ShuffleNet,in terms of both classification accuracy and computational efficiency.Conclusion The algorithm designed can accurately detect ST-T changes and can be used for wearable ECG automatic analysis to assist in the early warning of cardiovascular diseases in both acute and chronic patients and highland residents.[Chinese Medical Equipment Journal,2025,46(7):1-11]

Objective:To develop a risk prediction model for moderate to severe orthodontic-induced inflammatory root resorption (OIIRR) of maxillary incisors based on cone beam CT (CBCT) radiomics features and clinical characteristics of the orthodontic patients.Methods:Clinical and CBCT data from 101 orthodontic patients treated by the same attending orthodontist in the Department of Orthodontics, Stomatology Hospital of Tianjin Medical University from January 2019 to January 2024 were retrospectively collected. The sample included 42 class Ⅰ patients, 52 class Ⅱ patients and 7 class Ⅲ patients [age: (19.7±6.3) years], and a total of 394 maxillary incisors were analyzed. Potential influencing factors for moderate to severe OIIRR (root volume resorption rate≥10%) were collected from the patients′ CBCT and medical records, including initial age, gender, treatment duration, Angle′s classification, extraction or not, type of orthodontic appliance (fixed or clear aligner), changes in root inclination, root movement distance and direction, pre-treatment cephalometric measurements, pre-treatment root-bone relationship, pre-treatment root length, and pre-treatment radiomics features of the teeth. Univariate analysis was initially performed to screen for factors influencing moderate to severe OIIRR. Subsequently, least absolute shrinkage and selection operator (LASSO) regression, best subset regression, and random forest were used for feature selection to construct the OIIRR risk prediction model. The discrimination, calibration, and net benefit of the three risk prediction models were evaluated, and the optimal model was displayed using a nomogram.Results:LASSO regression identified clinical features including initial age (LASSO coefficient 0.052), treatment duration (LASSO coefficient 0.024), pre-treatment root length (LASSO coefficient -0.023), and vertical root movement distance (LASSO coefficient -0.029). Initial age and treatment duration were positively correlated with the severity of OIIRR, while root length and vertical root movement distance were negatively correlated. A total of 14 radiomics features were identified, including 2 original image features and 12 wavelet features. Best subset regression identified vertical root movement distance as the clinical feature and 7 radiomics features, including 1 original image feature and 6 wavelet features. The random forest model identified 8 wavelet features as important predictors, and all of which were radiomics features. Model performance evaluation showed that the random forest model had the highest discrimination, calibration, and net benefit, making it the optimal model, with radiomics features being the most important predictors.Conclusions:Based on the data from this study, radiomics features were identified as the most important predictors by the optimal model for OIIRR risk prediction. Predicting the occurrence of moderate to severe OIIRR before orthodontic treatment held potential clinical application value.
