Obesity and its related metabolic diseases have become a major global public health threat, and its rising incidence significantly increases the risk of cardiovascular and cerebrovascular diseases, diabetes and other complications. Pancreatic lipase is a key enzyme that converts food-borne lipids into triglycerides and fatty acids, and the effective inhibition of its activity has become an important strategy for the treatment of obesity. This paper discusses the screening methods of pancreatic lipase inhibitors, and summarizes and reviews the basic principles, advantages and disadvantages and application status of traditional screening methods, modern new screening methods and virtual screening methods. In view of the problems faced by the screening methods of pancreatic lipase inhibitors, future research urgently needs to move towards a collaborative innovation path of multi-technology integration, intelligent screening and complex systematization of traditional Chinese medicine, so as to open up new research paradigms.

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.

ObjectiveTo explore the effect of the medical-community linkage model on activities of daily living, psychological status and motor function of stroke patients in the community. MethodsA total of 60 stroke patients admitted to two community health service centers and their affiliated stations in Fengtai District, Beijing, from January, 2024 to August, 2025 were enrolled and randomly divided into control group (n = 30) and intervention group (n = 30). The control group received routine medicine, dietary care and rehabilitation management, while the intervention group underwent rehabilitation with the medical-community linkage model, for twelve weeks. They were assessed with modified Barthel Index (MBI), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD) and Fugl-Meyer Assessment (FMA) before and after intervention. ResultsAfter intervention, the MBI, HAMA, HAMD and FMA scores of patients improved in both groups (|t| > 5.599, P < 0.001), and improved more in the intervention group than in the control group (P < 0.05), except MBI. The HAMA and HAMD scores of family members decreased in both groups (|t| > 10.333, P < 0.001), and decreased more in the intervention group than in the control group (t > 5.681, P < 0.001). ConclusionThe medical-community linkage model can further improve the motor function of stroke patients in community, as well as the psychological status of both patients and their family members.

Objective To construct and compare logistic regression and decision tree models for predicting systemic inflammatory response syndrome (SIRS) in patients with type B aortic dissection (TBAD) after interventional surgery. Methods A retrospective analysis was conducted on clinical data of TBAD patients at Peking University Shenzhen Hospital from 2020 to 2024. The patients were divided into a SIRS group and a non SIRS group based on whether SIRS occurred within 24 hours after surgery. Multivariate logistic regression was used to analyze the influencing factors of SIRS occurrence in TBAD intervention patients, and a decision tree model was constructed using SPSS Modeler to compare the predictive performance of the two models. Results A total of 742 patients with TBAD were included, including 579 males and 163 females, aged 27-97 (58.85±10.79) years. Within 24 hours after intervention, a total of 506 patients developed SIRS, with an incidence rate of 68.19%. Logistic regression analysis showed that the extensive involvement of the dissection, the surgical time≥2 hours, PET coated stents implanted, serum creatinine, white blood cell count, C-reactive protein, monocyte (MONO), neutrophil count levels elevated, estimated glomerular filtration rate and decreased albumin levels were independent risk factors for SIRS (P<0.05). The decision tree model selected a total of 10 explanatory variables and 6 layers with 37 nodes, among which MONO was the most important predictor. The area under the decision tree model curve was 0.829 [95%CI (0.800, 0.856)], which was better than the logistic regression model's 0.690 [95%CI (0.655, 0.723)], and the difference was statistically significant (P<0.001). Conclusion The incidence of SIRS after TBAD intervention is high, and the decision tree model has better predictive performance than logistic regression. It can identify high-risk patients with higher accuracy and provide a practical tool for early clinical intervention.

ObjectiveTo investigate the potential mechanism of Shenqi Yiliu Formula （参芪抑瘤方） in treating precancerous lesions of gastric cancer （PLGC） by the Wnt/β-catenin signaling pathway. MethodsThe CCK-8 assay was used to determine the optimal intervention time for Shenqi Yiliu Formula drug-containing serum and the concentration of the Wnt/β-catenin pathway inhibitor XAV939 depends on the survival rate of AGS gastric cancer cell line. AGS cells were divided into the gastric cancer cell group （15% blank serum）， inhibitor group （selected concentration of XAV939）， high-dose Shenqi Yiliu Formula group （12% Shenqi Yiliu Formula drug-containing serum + 3% blank serum）， medium-dose Shenqi Yiliu Formula group （6% Shenqi Yiliu Formula drug-containing serum + 9% blank serum）， and low-dose Shenqi Yiliu Formula group （3% Shenqi Yiliu Formula drug-containing serum + 12% blank serum）. Each group was tested in triplicate. After culturing for 24 and 48 hours， cell migration and invasion were assessed by scratch assays； after a selected intervention period （48 hours）， cell cycle distribution was analyzed using flow cytometry， Ki67 protein levels were detected by immunofluorescence， the protein levels of Wnt， β-catenin， GSK-3β， and intranuclear T-cell specific factor（TCF） were measured by the protein immunoblotting assay， and the mRNA expressions of these above factors were determined by quantitative real-time PCR. ResultsThe optimal intervention time for Shenqi Yiliu Formula drug-containing serum was determined to be 48 hours， and the effective concentration of XAV939 was 20 μmol/L. Compared with the gastric cancer cell group， Shenqi Yiliu Formula at all doses reduced the cell migration rate at 24 and 48 hours （P＜0.05）， except for the low-dose group at 24 hours. Compared to the low-dose group at corresponding time points， high- and medium-dose Shenqi Yiliu Formula groups showed significantly reduced migration rates， particularly the high-dose group at 48 hours （P＜0.05）. Compared with the gastric cancer cell group， the high-dose Shenqi Yiliu Formula and inhibitor groups exhibited reduced protein and mRNA levels of Wnt， β-catenin， and TCF， along with reduced Ki67 protein levels and a decreased proportion of cells in the S and G2 phases of the cell cycle， but GSK-3β protein levels， GSK-3β mRNA expression， and the proportion of cells in the G1 phase increased （P＜0.05）. Compared to the inhibitor group， the high-dose Shenqi Yiliu Formula group showed a decreased proportion of G1-phase cells and an increased proportion of G2-phase cells （P＜0.05）， although differences in Wnt and β-catenin protein levels and mRNA expressions were not statistically significant （P＞0.05）. ConclusionShenqi Yiliu Formula drug-containing serum inhibits the migration and invasion of gastric cancer AGS cells and block the cell cycle at G1 phase， and its underlying mechanism may be related to the regulation of the Wnt/β-catenin signaling pathway.

Objective To establish a method for determination of pyriclobenzuron (PBU) residues in rice and paddy environments, and to determine the residual amounts and observe the degradation dynamics of PBU. Methods In July 2022, the paddies of Zhejiang Academy of Agricultural Sciences were selected as experimental fields, and were divided into the blank control group (no pesticide application), the 1-fold-concentration pesticide group (1 kg/667 m²), and the 5-fold-concentration pesticide group (5 kg/667 m²), with a 100 m² area in each group. At the early tillering stage of rice, 20% suspension of PBU sulfate was sprayed once in the 1-fold-concentration and 5-fold-concentration pesticide groups, and rice plants, paddy water and soil samples were collected 2 h, and 1, 2, 3, 5, 7, 11, 14, 21, 28, 35, 49 d and 63 d following spraying PBU, while rice straw, field soil, brown rice and rice husk samples were collected 98 d following spraying. PBU was extracted and purified in samples using a quick, easy, cheap, effective, rugged, and safe (QuEChERS) pretreatment technique, and the PBU contents were determined in samples using ultrahigh performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The solvent standard working solution and matrix standard working solution were prepared. A linear regression equation was fitted between PBU concentration (x-axis) and peak area (y-axis), and the ratio of the slope (k) of the matrix standard curve to the slope (K) of the solvent standard curve was calculated to evaluate the matrix effect of PBU in samples. According to the Guidelines for Pesticide Residue Testing in Crops (NY/T 788—2018), the addition levels of PBU were set at 0.005, 0.050, 5.000, 1 000.000 mg/kg in rice plants, 0.005, 0.050, 2.000, 10.000 mg/kg in paddy water, 0.005, 0.050, 2.000 mg/kg in soil, and 0.005, 0.050, 5.000 mg/kg in brown rice and rice husks. The recovery and relative standard deviation (RSD) of PBU addition were calculated to evaluate the effectiveness of UPLC-MS/MS for determination of PBU contents. The first-order kinetic equation of PBU concentration was fitted in samples at different sampling time points to analyze the trends in PBU degradation in rice plants, paddy water, and soil, and the half-life of PBU was calculated in different samples. Results There was a good linear relationship between the mass concentration and peak area of PBU at concentrations of 0.000 1 to 0.020 0 mg/kg under solvent and matrix conditions (R² = 0.985 8 to 0.999 7, t = -0.47 to 1.62, all P values < 0.01). The matrix effects of PBU were 70.26%, 65.42% and 65.12% in rice plants, brown rice and rice husks, indicating a matrix-inhibitory effect, and the matrix effect was 87.06% in soils, indicating a weak matrix effect. The recovery of PBU addition was 77.61% to 100.12% in different samples, with RSD of 1.43% to 6.74%, and a limit of quantification (LOQ) of 0.005 mg/kg, and the addition recovery and RSD met the requirements of the Guidelines for Pesticide Residue Testing in Crops (NY/T 788—2018), validating the effectiveness of UPLC-MS/MS assay. Following spraying PBU at a dose of 1 kg/667 m², the half-life of PBU was 6.24 d in rice plants and 3.43 d in paddy water samples, respectively. The final residues of PBU were lower than the LOQ of 0.005 mg/kg in brown rice and rice husk samples 98 d following spraying PBU. Following spraying PBU at a dose of 5 kg/667 m², the half-life of PBU was 15.75 d in rice plants and 7.62 d in paddy water samples, respectively. The final residue of PBU was lower than the LOQ of 0.005 mg/kg in brown rice 98 d following spraying PBU, and the final residue of PBU was 0.049 mg/kg in rice husks. Conclusions A simple, and highly accurate and precise UPLC-MS/MS assay has been developed for determination of PBU residues in rice plants and paddy environments through extraction and purification of PBU from matrix samples using QuEChERS pretreatment. After spraying PBU in paddies, the concentration of PBU gradually decreases in rice plants and paddy water over time, and the final residual concentration is low.

Breast cancer is the leading cause of cancer-related mortality among women worldwide and has drawn extensive research attention.Owing to its molecular heterogeneity,drug resistance,and low therapeutic response,single-modality treatments often fail to achieve satisfactory efficacy or broad applicability.Combination therapy,designed based on the pathophysiological characteristics,related signaling pathways,and biomarkers of breast cancer,has emerged as a promising approach for improving therapeutic outcomes.With the advancement of research on combination strategies,the understanding of their molecular mechanisms—particularly key signaling pathways and biomarkers—has become increasingly important.However,comprehensive reviews addressing these molecular mechanisms and synergistic strategies remain scarce.This article summarizes recent advances in combination therapy for breast cancer,providing a comprehensive review of recent combination therapies for breast cancer and their underlying molecular mechanisms,and focusing on key signaling pathways involved in combination therapy and synergistic strategies,thereby providing theoretical insights and reference for researchers,graduate students,and clinicians engaged in the development of novel combination therapeutic strategies for breast cancer and related malignancies.

Objective:To explore the effect of fibroblast growth factor 2(FGF2)on ferroptosis of renal fibrotic cells and its po-tential molecular mechanisms.Methods:Rat NRK-52E cells were randomly divided into control group,renal fibrosis model group,FGF2 cytokine stimulation group,knockdown empty plasmid group,si-FGF2 group,overexpression empty plasmid group,overexpres-sion FGF2 group,Fer-1 treatment group.The model group was treated with TGF-β1 to obtain a renal fibrosis cell model.Cellular im-munofluorescence method was used to measure the level of cell fibrosis.Western blot was used to detect ferroptosis-related proteins(Nrf2,GPX4 and SLC7A11)and pathway proteins(STAT3,p-STAT3)expression level in the cells.Results:Knockdown of FGF2 could alleviate the increase in α-SMA and Collagen Ⅲ proteins caused by TGF-β1 stimulation of renal tubular cells(P<0.05).FGF2 could promote the activation of STAT3 protein into p-STAT3.The expression level of SLC7A11 protein was significantly increased after FGF2 cytokine stimulation(P<0.05).Compared with the control group,the expressions of Nrf2 and GPX4 in renal fibrotic cells in the si-FGF2 group and Fer-1 treated group were significantly reduced(P<0.05).In addition,knockdown of FGF2 significantly reduced in-terstitial fibrosis of renal tubular epithelial cells(P<0.05).Conclusion:FGF2 may mediate TGF-β1-induced renal ferroptosis through the STAT3/SLC7A11 signaling pathway,and knock down of FGF2 can improve fibrosis of renal tubular epithelial cells.

Objective:To investigate whether systemic immune inflammation index(SII)-C-reactive protein/albumin(CRP/Alb)can predict postoperative survival in non-small cell lung cancer(NSCLC)patients.Methods:A total of 262 patients with NSCLC who underwent surgery in Hebei Provincial People's Hospital from January 2017 to November 2020 were included.SII and CRP/Alb expressions in patients after surgery were analyzed by K-M survival curve analysis,Cox multivariate risk regression analysis and ROC curve analysis.Results:Patients with high SII expression(>961.78)and high CRP/Alb expression(>0.025)had worse outcomes than patients with low SII and CRP/Alb expressions,respectively(P<0.001).SII-CRP/Alb score(P=0.032),age≥60 years(P=0.038)and T stage T2～T3(P<0.001)were significantly associated with shorter overall survival.AUC of SII-CRP/Alb scores were larger than SII and CRP/Alb scores,respectively.Conclusion:SII-CRP/Alb score can effectively evaluate postoperative survival status of patients with NSCLC,and SII-CRP/Alb score are independent predictors of postoperative overall survival in NSCLC patients.

Objective Network pharmacology and molecular docking techniques were used to predict the potential mechanisms by which the active components of Piper nigrum(PN)regulate depressive-like behaviors in chronic restraint stress(CRS)mice.Methods The major chemical components and targets of PN were screened using the Traditional Chinese Medicine Systems Pharmacology database.Targets related to ferroptosis and depression were obtained from the Online Mendelian Inheritance in Man,GeneCards,and FerrDB databases.The intersecting targets were then subjected to Gene Ontology and Kyoto Encyclopedia of Genes and Gnomes(KEGG)pathway enrichment analyses,and molecular docking was performed to validate the binding capacities between the core targets and their corresponding active components.Finally,we established a CRS mouse model.Mice were treated with PN 75,150,and 300 mg/kg for 4 weeks,followed by behavioral assessments and reverse transcription-quantitative polymerase chain reaction(RT-qPCR)to verify the expression of core genes.Results Nine active components were screened from PN,corresponding to 27 targets,and 8377 targets related to depression and 547 targets associated with ferroptosis were screened from the databases.The intersection of these three sets resulted in 25 target genes.KEGG enrichment analysis revealed that these core targets were predominantly enriched in signaling pathways,including cholinergic synapses,serotonergic synapses,and neuroactive ligand-receptor interactions.Molecular docking result showed that the main active components of PN had strong binding affinities for the targets CHRM2,SLC6A4,PTGS2,and SLC6A2.Behavioral assessments demonstrated that PN significantly increased the sucrose preference index(P＜0.01,P＜0.001),reduced immobility time in the tail suspension and forced swimming tests(P＜0.01,P＜0.001),and enhanced exploratory behavior in the open field test(P＜0.05.P＜0.01,P＜0.001).PN significantly reduced the serum levels of inflammation markers(P＜0.05.P＜0.01,P＜0.001),as shown by enzyme-linked immunosorbent assay,and neurotransmitter analysis revealed that PN significantly increased the levels of serotonin and acetylcholine in the mouse hippocampus(P＜0.05).RT-qPCR showed that PN demonstrated the mRNA expression of SLC6A4(P＜0.05.P＜0.01,P＜0.001).Conclusions PN may improve depressive-like behavior in mice by modulating serotonin and acetylcholine levels,inhibiting inflammatory responses,participating in immune regulation,and exerting neuroprotective effects.
