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.

This study explored the mechanism of Xiangsha Liujunzi Decoction(XSLJZD) in the treatment of functional dyspepsia(FD) based on inositol-requiring enzyme 1(IRE1)/apoptosis signal-regulating kinase 1(ASK1)/c-Jun N-terminal kinase(JNK) pathway-mediated autophagy in interstitial cells of Cajal(ICC). Forty-eight SPF-grade male SD suckling rats were randomly divided into a blank group and a modeling group, and the integrated modeling method(iodoacetamide gavage + disturbance of hunger and satiety + swimming exhaustion) was used to replicate the FD rat model. After the model replications were successfully completed, the rats were divided into a model group, high-dose, medium-dose, and low-dose groups of XSLJZD(12, 6, and 3 g·kg~(-1)·d~(-1)), and a positive drug group(mosapride of 1.35 mg·kg~(-1)·d~(-1)), and the intervention lasted for 14 days. The gastric emptying rate and intestinal propulsion rate of rats in each group were measured. The histopathological changes in the gastric sinus tissue of rats in each group were observed by hematoxylin-eosin(HE) staining. The ultrastructure of ICC was observed by transmission electron microscopy. The immunofluorescence double staining technique was used to detect the protein expression of phospho-IRE1(p-IRE1), TNF receptor associated factors 2(TRAF2), phospho-ASK1(p-ASK1), phospho-JNK(p-JNK), p62, and Beclin1 in ICC of gastric sinus tissue of rats in each group. Western blot was used to detect the related protein expression of gastric sinus tissue of rats in each group. Compared with those in the blank group, the rats in the model group showed decreased body weight, gastric emptying rate, and intestinal propulsion rate, and transmission electron microscopy revealed damage to the endoplasmic reticulum structure and increased autophagosomes in ICC. Immunofluorescence staining revealed that the ICC of gastric sinus tissue showed a significant elevation of p-IRE1, TRAF2, p-ASK1, p-JNK, and Beclin1 proteins and a significant reduction of p62 protein. Western blot revealed that the expression levels of relevant proteins in gastric sinus tissue were consistent with those of proteins in ICC. Compared with the model group, the body weight of rats in the high-dose and medium-dose groups of XSLJZD was increased, and the gastric emptying rate and intestinal propulsion rate were increased. Transmission electron microscopy observed amelioration of structural damage to the endoplasmic reticulum of ICC and reduction of autophagosomes, and the p-IRE1, TRAF2, p-ASK1, p-JNK, and Beclin1 proteins in the ICC of gastric sinus tissue were significantly decreased. The p62 protein was significantly increased. Western blot revealed that the expression levels of relevant proteins in gastric sinus tissue were consistent with those of proteins in ICC. XSLJZD can effectively treat FD, and its specific mechanism may be related to the inhibition of the expression of molecules related to the endoplasmic reticulum stress IRE1/ASK1/JNK pathway in ICC and the improvement of autophagy to promote gastric motility in ICC.

Objective:To explore the prognostic influencing factors of patients with pulmonary large cell neuroendocrine carcinoma (LCNEC), to develop a nomogram-based predictive model for the overall survival (OS) of LCNEC patients and to make validation.Methods:The clinical data of 2 947 patients with LCNEC in the Surveillance, Epidemiology, and End Results (SEER) database (the modeling group) and 147 patients with LCNEC in Beijing Chest Hospital Affiliated to Capital Medical University from 2010 to 2023 (the validation group). The data of patients in the both groups were compared. Cox proportional hazards model was used to screen out the factors influencing the OS of patients with LCNEC. A nomogram model was constructed to predict the OS based on the multivariate analysis result. Internal validation of the predictive model's performance was conducted through 500 repeated samplings based on the Bootstrap method. The predictive performance of the nomogram model was evaluated by using the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. The consistency index (CI) was used to analyze the discrimination of the nomogram model in predicting the survival of LCNEC patients; calibration curves were used to analyze the consistency between the survival predicted by the nomogram model and the actual survival outcomes; and the decision curve analysis (DCA) was used to assess the net benefit of the model for actual clinical decision-making.Results:The differences in the proportions of patients with different age, gender, race, tumor staging, N stage, M stage, hepatic metastasis or not, pulmonary metastasis or not, chemotherapy and radiotherapy or not between the modeling group and the validation group were statistically significant (all P < 0.05). The median OS time of LCNEC patients in the modeling group was 14.0 months, with the 1-year OS rate of 53.3% and the 5-year OS rate of 21.2%; the median OS time of LCNEC patients in the validation group was 17.5 months, with the 1-year OS rate of 58.7%; there was no statistically significant difference in OS between the 2 groups ( P = 0.280). In the modeling group, the median OS time of female and male LCNEC patients was 18.0 and 12.0 months, respectively, and the difference in OS between the 2 groups was statistically significant ( P < 0.05); for patients with stage Ⅰ-Ⅱ, Ⅲ, and Ⅳ LCNEC, the median OS time was 48.0, 16.0, and 6.0 months, respectively, and the difference in OS among the 3 groups was statistically significant ( P < 0.05); the median OS time of patients receiving surgery and not receiving surgery was 28.0 and 8.0 months, respectively, and the difference in OS between the 2 groups was statistically significant ( P < 0.05). The differences in OS among female and male, patients in stages Ⅰ-Ⅱ, Ⅲ and Ⅳ, patients who underwent surgery or not were statistically significant (all P < 0.05). The results of multivariate Cox regression analysis in the modeling group showed that patients aged >60 years old (>60 years old vs. ≤60 years old: HR = 1.234, 95% CI: 1.114-1.367, P < 0.01), M 1 stage (M 1 stage vs. M 0 stage, HR = 2.646,95% CI: 2.385-2.935, P < 0.001), T 2-4 stage (T 2-4 stage vs. T 1 stage: HR = 1.199, 95% CI: 1.147-1.252, P < 0.001), N 1-3 stage (N 1-3 stage vs. N 0 stage: HR = 1.281, 95% CI: 1.225-1.340, P < 0.001) were independent risk factors of the OS in patients with LCNEC; female (female vs. male: HR = 0.877, 95% CI: 0.805-0.956, P = 0.003), surgery (yes vs. no: HR = 0.612, 95% CI: 0.554-0.676, P < 0.001), chemotherapy (yes vs. no: HR = 0.520, 95% CI: 0.470-0.575, P < 0.001) were independent protective factors of the OS in patients with LCNEC. A nomogram model for predicting 1, 3, and 5-year OS rates of LCNEC patients was constructed based on age, gender, T stage, N stage, M stage, surgery and chemotherapy. The result of ROC curve analysis indicated that the AUC of the nomogram model for predicting 1, 3, and 5-year OS rates in the modeling group was 0.822, 0.821 and 0.821, respectively, while the AUC of 1-year OS rate predicted by the validation group was 0.660. The CI of the modeling group and the validation group was 0.756 and 0.660, respectively. The calibration curve showed that 1, 3, and 5-year OS rates predicted by the modeling group were highly consistent with the actual OS rates. The DCA showed that the nomogram model for predicting OS in the modeling group and the validation group both had good clinical net benefits. Conclusions:The constructed nomogram model for predicting the prognosis of LCNEC patients is proved to be reliable and has good clinical values.

Background and purpose:Intracellular deubiquitylating enzymes,such as ubiquitin-specific peptidase 2(USP2),play a pivotal role in regulating protein degradation and cellular homeostasis by modulating protein ubiquitin deconjugation,which have been implicated in the proliferation and survival of multiple myeloma(MM)cells.Targeting the inhibition of USP2 activity in MM cells might modulate their biological behavior.This study aimed to investigate regulatory effects of the leukotriene receptor antagonist montelukast sodium on USP2 in MM cells and its subsequent biological effects.Methods:An in vitro deubiquitination reaction system was established using purified USP2 protein and its substrate,the glutathione S-transferase(GST)tagged ubiquitin A-52 residue ribosomal protein fusion product(UbA52),known as GST-UbA52 protein.This system was used to characterize inhibitory effects of montelukast sodium on USP2 deubiquitinase activity.The MM cell lines MM1.S and H929 were used as in vitro models.Cellular thermal shift assay(CETSA)was subsequently employed to test interaction mode between montelukast sodium and USP2 in MM cells.Western blot assay was applied to detect expression levels of USP2 and its targeting regulators,including cell cycle supervisors cyclin D1(CCND1)and cyclin A1(CCNA1),classical signaling transducer KRAS and glucose regulated protein 78kD(GRP78),as well as apoptotic molecule C/EBP-homologous protein(CHOP)in MM1.S and H929 cells before and after the treatment with different concentrations of montelukast sodium.MM cells with either overexpression(H929-OE,MM1.S-OE)or knockdown(H929-LE,MM1.S-LE)of USP2 were generated using a lentiviral vector.Cell counting kit-8(CCK-8)and flow cytometry were utilized to detect the proliferation and apoptotic rates of H929-OE,MM1.S-OE,H929-LE and MM1.S-LE cells treated with montelukast sodium.Results:Montelukast sodium was found to inhibit USP2 mediated degradation of GST-UbA52 protein in a concentration-dependent manner,with a half inhibitory concentration(IC50)of 3.814 μmol/L.Additionally,montelukast sodium significantly enhanced the thermal stability of USP2 at temperatures of 49.1,53.2 and 56.4℃.It was also shown that montelukast sodium could down-regulate expressions of CCND1,CCNA1 and KRAS,while increase levels of GRP78 and CHOP in MM1.S and H929 cells.Furthermore,after treating with 40 μmol/L montelukast sodium for 24 h,the proliferation inhibition and apoptotic rate of H929-OE cells reached to(37.68±1.10)%and(18.99±0.26)%,while the proliferation inhibition and apoptotic rate of MM1.S-OE cells reached to(24.48±0.49)%and(33.29±0.75)%,which were significantly lower than those in H929 and MM1.S cells[H929:(57.19±1.93)%and(45.65±0.24)%;MM1.S:(50.04±0.53)%and(40.25±0.91)%;P＜0.05,n=3].Conversely,the proliferation inhibition and apoptotic rates of H929-LE and MM1.S-LE cells were significantly higher[H929-LE-1#:(80.70±1.60)%and(89.08±0.49)%;H929-LE-2#:(75.30±3.80)%and(82.41±1.07)%;MM1.S-LE-1#:(70.64±0.84)%and(67.63±0.21)%;MM1.S-LE-2#:(68.47±1.32)%and(85.90±0.18)%;P＜0.05,n=3].Conclusion:Montelukast sodium can target ubiquitin proteasome regulator USP2 and inhibit its deubiquitylating activity,which may modulate USP2 directing protein and trigger endoplasmic reticulum stress to induce cell cycle arrest and apoptosis in MM cells.

Objective: To evaluate the therapeutic potential and underlying mechanisms of action of propolis in db/db mice. Methods: The chemical composition of propolis was analyzed using UHPLC-MS/MS. Thirty mice, including six wt/wt and 24 db/db mice, were randomly assigned to four groups (n = 6 per group): control, model, metformin (250 mg/kg), low dose propolis (100 mg/kg), and high dose propolis (HDP; 400 mg/kg). Treatments were administered orally for four weeks. Body weight and FBG levels were recorded weekly, and an oral glucose tolerance test was conducted on the 25th day. Serum levels of FIN, GSP, connecting peptide, AST, ALT, HDL, LDL, TG, and TC were quantified using ELISA. Liver histopathology was assessed using H&E and PAS staining. Western blotting was performed to examine the expression levels of NF-κB, phosphorylated NF-κB, IκBα, pIκBα, and AKT in liver tissues. Results: The top 10 metabolites of propolis were identified in positive and negative ion modes. The HDP group exhibited a significant reduction in FBG levels, body weight, connecting peptide levels, homeostatic model assessment of β-cell function scores, and homeostasis model assessment of insulin resistance scores (all P < .05). GSP levels were significantly reduced in both treatment groups (all P < .001). The HDP group also exhibited a reduction in TC and LDL levels (both P < .05), whereas HDL levels increased in both treatment groups (all P < .05). Liver weight, AST levels, and ALT levels were reduced in both treatment groups (all P < .05). Histological analysis revealed improved liver morphology. Protein analysis demonstrated downregulation of phosphorylated NF-κB and phosphorylated IκB, alongside upregulation of AKT. Conclusion Propolis exhibited significant antihyperglycemic effects in db/db mice, potentially by modulating the AKT and NF-κB signaling pathways, highlighting its potential as a therapeutic agent for diabetes management.
