ObjectiveTo investigate the value of preoperative dual-layer spectral detector CT （DLCT） parameters in predicting lymph node metastasis （LNM） of non-functional pancreatic neuroendocrine neoplasms （NF-pNENs）. MethodsA retrospective study was conducted on patients with pathologically confirmed NF-pNENs who underwent preoperative contrast-enhanced DLCT examination between September 2019 and July 2024. Regions of interest （ROIs） were manually delineated on three representative slices of the solid component of the lesion， and the mean values were recorded. Conventional CT parameters， monochromatic energy images （40 keV， 70 keV， 100 keV）， iodine concentration maps， and effective atomic number （Z_eff） maps in the pancreatic parenchymal phase and portal venous phase were acquired. A total of 34 parameters， including clinical characteristics， imaging features， conventional CT and DLCT quantitative parameters， were analyzed. Intergroup differences were compared between the LNM and non-LNM groups. Independent predictive factors were screened using logistic regression and least absolute shrinkage and selection operator （LASSO） regression. Receiver operating characteristic （ROC） curves were generated for each predictive model， and the area under the curve （AUC） was calculated to evaluate the predictive efficacy. ResultsA total of 82 patients with NF-pNENs were enrolled， including 37 males and 45 females， with a mean age of 49.7±14.7 years. Thirty patients were performed with LNM and 52 were with non-LNM. After univariate logistic regression， LASSO regression and multivariate stepwise logistic regression analyses， body mass index （BMI）， organ invasion， normalized CT value in the portal venous phase （nCTv） and normalized iodine concentration in the portal venous phase （nICv） were identified as independent predictive factors. The AUCs of the clinical-radiological qualitative model （BMI+organ invasion）， conventional CT model （nCTv）， DLCT model （nICv） and comprehensive model （organ invasion+nICv） were 0.815 （0.719， 0.910）， 0.750 （0.642， 0.858）， 0.829 （0.733， 0.925） and 0.865 （0.879， 0.953）， respectively. The comprehensive model combining clinical-radiological and DLCT characteristics exhibited superior predictive performance. ConclusionDLCT parameters are more effective than conventional CT parameters in predicting LNM in NF-pNENs， enabling non-invasive preoperative prediction and assisting clinical decision-making.

OBJECTIVE To evalu ate relat ed researches about the cost- benefit of pharmaceutical care in medical institutions with cost- benefit analysis，in order to provide evidence-based basis for related policy decisions and provide methodological reference for the cost- benefit evaluation of pharmaceutical care in the future. METHODS Retrieved from PubMed ，Embase，the Cochrane Library ，CBM，Wanfang database ，VIP and CNKI ，cost-benefit analysis was used to evaluate the researches about the cost-benefit of pharmaceutical care in medical institutions. Two researchers independently screened the research and extracted data according to the “Consolidated Health Economic Evaluation Reporting Standards Checklist ”. The quality of included studies was scored and evaluated systematically. RESULTS A total of 46 studies from 17 countries were included. Most of them came from the United States （21.74％），China（19.57％）and France （8.70％）. Average score of 46 literature was 14.30，of which 1 literature was excellent ，5 literature were good ，25 literature were qualified and 14 literature were unqualified. There were 25 research protocols of prospective study type ；the type of pharmaceutical care involved mostly was pharmaceutical monitoring （60.87％）， followed by prescription review （23.91％），medication reconciliation （8.70％）and outpatient pharmacy （6.52％）were less. The median cost-benefit ratio of pharmaceutical care was 5.05 （3.08，11.28）. CONCLUSIONS Pharmaceutical care shows good economic value ，and pharmacists have played an important role in saving medical resources ，but the design level and report quality of the existing studies need to be improved.

OBJECTIVE： To investigate the protective effect and its mechanism of thymoquinone （TQ） on myocardial fibrosis （MF） induced by lipopolysaccharide in rats. METHODS： Totally 40 male Wistar rats were randomly divided into control group， model group， TQ low-dose and high-dose groups [5， 10 mg/（kg?d）]， with 10 rats in each group. Except that control group was given constant volume of normal saline intraperitoneally， other groups were given LPS intraperitoneally to induce MF model， once a day， for consecutive 3 weeks. Since the first day of modeling， administration group was given relevant medicine intraperitoneally， once a day， for consecutive 3 weeks. After last medication， ELISA method was used to detect the contents of serum inflammation factors （IL-1β， IL-6， TNF-α） in rats. Cardiac mass parameters （HW/BM， LVW/BW） were weighed and calculated. HE staining was used to observe the histopathological changes of myocardial tissue. The contents or activities of oxidative stress indicators （MDA， SOD） and myocardial collagen indexes （HYP， Col-Ⅰ， Col-Ⅲ） were detected by chemical analysis， xanthine oxidase method or ELISA. mRNA expression of regulation genes （Col-Ⅰ， Col-Ⅲ， MMP-3， MMP-9， TGF-β1 and Smad3） related to myocardial fibrosis were determined by real-time fluorescence quantitative PCR. RESULTS： Compared with control group， there were swollen myocardial cells， disordered nuclei of different sizes and visible fiber hyperplasia in model group； the levels of serum inflammatory factors and LVW/BW， cardiac contents of MDA， HYP， Col-Ⅰand Col-Ⅲ， mRNA expression of Col-Ⅲ， TGF-β1 and Smad3 in model group were increased significantly （P＜0.05）， while SOD activity was decreased significantly （P＜0.05）. Compared with model group， the degree of myocardial fibrosis was improved in TQ groups to different extents； serum content of IL-1β and the contents of MDA， HYP and Col-Ⅰ in cardiac tissue in TQ low-dose group， serum contents of IL-1β， IL-6 and TNF-α， LVW/BW and the contents of MDA， HYP， Col-Ⅰ and Col-Ⅲ in cardiac tissue of TQ high-dose group as well as mRNA expression of Col-Ⅰ， Col -Ⅲ， TGF-β1 in TQ groups were decreased significantly （P＜0.05）. The activities of SOD in cardiac tissue were increased significantly in TQ groups （P＜0.05）. There was no statistical significance in other indexes among groups （P＞0.05）. CONCLUSIONS： TQ can protect against MF model rats to certain extent， the mechanism of which may be associated with the inhibition of inflammation reaction and oxidant stress reaction， and down-regulation of mRNA expression of Col-Ⅰ， Col-Ⅲ and TGF-β1.
