OBJECTIVE To explore a new model of intelligent medication education for pharmaceutical outpatient clinics by constructing dynamic HTML web pages through the DeepSeek-V3-0324 large-scale model. METHODS Clinical pharmacists integrated key clinical information such as patients’ basic information， medication history and medication precautions in real time， and generated a standardized medication education list through the DeepSeek-V3-0324 large-scale model and manual review. RESULTS The DeepSeek-V3-0324 large-scale model was applied in the pharmaceutical outpatient clinics to generate a personalized medication education list， which could effectively solve the disunity of pharmacy guidance caused by the lack of standardization of medication education and the difference of individualized experience of pharmacists in the traditional pharmaceutical outpatient clinics in the face of complex cases， and medication errors caused by forgetting or misremembering information among certain special patient populations after receiving medication education. CONCLUSIONS The transformation and application of artificial intelligence technology in pharmaceutical outpatient clinics is an innovation of pharmaceutical outpatient service means， which can provide patients with immediate and personalized medication education and improve the quality of pharmaceutical care. However， it is also necessary to face the lag of database update and the lack of risk management， as well as the lack of diversification of medication education lists.

Aim To explore the potential genes and mechanism of alisol B in the treatment of non-small cell lung cancer(NSCLC).Methods The proliferation and migration of NSCLC cells were detected by CCK-8 and Transwell.Genes of NSCLC and alisol B were col-lected through TCGA and compound gene prediction database,and their intersection genes were obtained.The network of protein-protein interaction(PPI)was constructed by using String database,and the top 20 key nodes were screened out,and the prognosis-related proteins related to the prognosis of NSCLC were screened out by using R language,and the intersection of them was obtained.The potential mechanism of ali-sol B on NSCLC was explored by KEGG and GO en-richment analysis and the relationship between related genes and immune cells,which was verified by cell-lev-el experiments.Results Alisol B inhibited the cell activity and migration ability of NSCLC cells.Five im-portant genes were identified by network pharmacologi-cal analysis:CCNE1,CDK1,COL1A1,COL1A2 and COL3A1.The results of cell experiment showed that al-isol B down-regulated the expression of Cyclin E1,CDK1 and COL1A2 in NSCLC cells.In addition,alisol B could inhibit the expression of COL1A2 and M2 macrophage marker CD206 in macrophages.Conclu-sions Alisol B may inhibit the proliferation of tumor cells by down-regulating CDK1 and Cyclin E1,and may affect the function of macrophages by inhibiting COL1A2,thus regulating the tumor immune microenvi-ronment and inhibiting NSCLC.

OBJECTIVE To evaluate the mechanisms underlying the antidepressant effect of ZBH2012001,a novel serotonin and norepinephrine reuptake inhibitor(SNRI),in general and its ability to enhance monoaminergic transmission and suppress neuroinflammation in particular.METHODS① Male ICR mice were divided into vehicle(distilled water),duloxetine(DLX,10 or 20 mg·kg-1)and ZBH2012001(5,10 and 20 mg·kg-1)groups.One hour following ig administration,the antidepressant effect of ZBH2012001 was evaluated using the tail suspension test(TST)and forced swimming test(FST).② Radioligand binding assay was conducted to evaluate the affinity of ZBH2012001 for human serotonin transporters(hSERTs)and human norepinephrine transporters(hNETs).③ Mice were divided into vehicle(distilled water),DLX(10 or 20 mg·kg-1)and ZBH2012001(5,10 and 20 mg·kg-1)groups.One hour following drug administration,the 5-hydroxytryptophan(5-HTP)-induced head-twitch test or yohimbine-induced lethality test were performed to evaluate the effect of ZBH2012001 on the function of the 5-hydroxytryptamine(5-HT)and norepinephrine(NE)systems.④ Mice were divided into vehicle(distilled water+0.1%acetic acid),reserpine model(distilled water+reserpine 5 mg·kg-1),DLX(DLX 20 mg·kg-1+reserpine 5 mg·kg-1)and ZBH2012001(ZBH2012001 5,10 and 20 mg·kg-1+reserpine 5 mg·kg-1)groups.One hour following drug administration,reserpine was injected intraperitoneally to establish a monoamine-depletion model.The ptosis,akinesia,and hypothermia assays were performed to evaluate the effect of ZBH2012001 on the down-regulation of the reserpine-induced monoamine system.The TST in mice was used to evaluate the effect of ZBH2012001 on reserpine-induced depressive-like behavior while high-performance liquid chromatography with electrochemical detection(HPLC-ECD)was used to measure the levels of monoamines and their metabolites in the hippocampal tissue of reserpine-induced monoamine-depletion mice.ELISA was employed to detect the contents of tumor necrosis factor-alpha(TNF-α)and interleukin-6(IL-6)in the hippocampal tissue of reserpine-induced monoamine-depletion mice.Western blotting was used to assess the expressions of ionized calcium-binding adapter molecule-1(Iba-1)and nuclear factor-kappa B(NF-κB)in the hippocampal tissue of reserpine-induced monoamine-depletion mice.RESULTS ① Compared with the vehicle group,ZBH2012001(5,10 and 20 mg·kg-1)significantly reduced the immobility time both in the TST in mice(P<0.01,respectively),and ZBH2012001(20 mg·kg-1)and in the FST in mice(P<0.05).② ZBH2012001 competitively inhibited the binding of[3H]-imipramine to hSERTs and[3H]-nisoxetine to hNETs,with the half maximal inhibitory concentration(IC50)values of 84.95 and 712.90 nmol·L-1,respectively.③Com-pared with the vehicle group,ZBH2012001(10 and 20 mg·kg-1)significantly increased the head twitches induced by 5-HTP in mice(P<0.01,respectively)and increased the mortality rate in mice induced by yohimbine(P<0.05,P<0.01).④ In the reserpine-induced monoamine-depletion model in mice,compared with the vehicle group,mice in the reserpine model group exhibited ptosis,akinesia and hypothermia feature(P<0.01,respectively),significantly prolonged immobility time in the TST(P<0.01),significantly decreased the levels of NE,5-HT and dopamine(DA)(P<0.05,P<0.01),significantly increased the metabolic conversion rate of 5-HT and DA(P<0.01,respectively),significantly elevated levels of TNF-α and IL-6(P<0.05,respectively),and significantly increased expressions of Iba-1 and NF-κB(P<0.05,respectively)in the hippocampus.Compared with the model group,ZBH2012001(5,10 and 20 mg·kg-1)significantly antagonized ptosis and hypothermia behaviors induced by reserpine(P<0.01,respectively),ZBH2012001(10 and 20 mg·kg-1)significantly shortened the immobility time in reserpine-treated mice(P<0.05,P<0.01),ZBH2012001(20 mg·kg-1)significantly increased the levels of NE and 5-HT in the hippocampus of reserpine-treated mice(P<0.05,respectively),decreased the metabolic conversion rate of 5-HT(P<0.05),significantly reduced the contents of TNF-α and IL-6 in the hippocampus of reserpine-treated mice(P<0.05,respectively),ZBH2012001(5,10 and 20 mg·kg-1)significantly reduced the expression of Iba-1 protein in the hippocampus of reserpine-treated mice(P<0.01,respec-tively),and ZBH2012001(20 mg·kg-1)significantly reduced the expression of NF-κB protein in the hippocampus of reserpine-treated mice(P<0.05).CONCLUSION ZBH2012001 exerts its antidepres-sant effect through a dual mechanism involving monoamine enhancement and inflammation suppres-sion.

We investigated the prevalence and spatial distribution characteristics of T.gondii infection in cats in China,to provide a scientific basis for the prevention and con-trol of T.gondii.We searched PubMed,CNKI,Wanfang Da-tabase,and Baidu Academic Database to retrieve studies on the seroprevalence of T.gondii in domestic cats published by December 31,2023,in China,to investigate the spatial loca-tion and expression of T.gondii infection in China by using Geographical Information Systems(GIS).SPSS 26.0 software was used for statistical analysis.A total of 86 eligible studies published between 1984 and 2023 were included in this study,covering 28 provincial administrative regions and involving 20 722 cats.The ArcGIS classification results indicated that the overall positivity rate of T.gondii in domestic cats was 14.78％(3 080/20 836,95％CI:14.07％-15.03％).No epidemiological study of T.gondii infection in cats has been reported in Tibet,Tianjin,Hainan,Hong Kong,Ma-cao,or Taiwan.The prevalence of T.gondii infection in cats was highest in Shanxi Province(60％,54/90,95％CI:49.82％-70.18％),followed by Hebei Province(57.33％,43/75,95％CI:46.07％-68.59％),Henan Province(45.53％,173/380,95％CI:46.07％-68.59％),and Yunnan Province(43.64％,24/55,95％CI:30.49％-56.79％).The lowest seroprevalence of T.gondii antibody was found in Jiangxi Province(2.47％,2/81,95％CI:-0.90％-5.90％).Furthermore,the seropreva-lence of T.gondii in cats in northern China was 14.12％(2 044/14 491 95％CI:12.34％-15.90％),whereas that in southern China was 16.30％(1 036/6 355 95％CI:15.40％-17.20％).Significant differences were observed between them(x2=16.60,P＜0.05).The temporal distribution results indicated a decrease in the overall seroprevalence of T.gondii in cats in China from 1984 to 2023.Our findings suggested that T.gondii in cats is widespread in China,with a stable epidemic cycle,and the rates of Toxoplasma positivity vary greatly among regions.The increasing prevalence of pet cats in China,and the close rela-tionship between these cats and humans,may pose substantial exposure risks to a large susceptible population.Therefore,the association between cat ownership and T.gondii infection in humans,and how to decrease human environmental contamination through cat exposure to T.gondii and T.gondii oocysts,requires further investigation.

Metastasis is the main risk factor for poor prognosis of laryngeal squamous cell carcinoma (LSCC) .Chemokines are closely related to metastasis in the tumor microenvironment.CXCL8 is a cyto-kine-like secreted protein that plays key roles in the malignant development of a variety of tumors,but has not been elucidated in LSCC.In this paper,we elucidated the role of CXCL8 in LSCC cells and found miRNAs that targeted CXCL8,which may become new targets for the diagnosis and treatment of LSCC.Firstly,the GEPIA showed that CXCL8 was highly expressed in head and neck cancer (P<0.05).The real-time fluorescence quantification (qRT-PCR) found that CXCL8 was highly expressed in LSCC cells.The enzyme-linked immunoassay also found that CXCL8 was highly secreted in the superna-tant of LSCC cells (P<0.001) .Then,the CCK8 assay confirmed that knockdown of CXCL8 significant-ly inhibited the proliferation of FD-LSC-1 and AMC-HN8 cells (the average inhibition rate was 34.0％and 19.5％,respectively);The EdU assay also confirmed that knockdown of CXCL8 significantly inhibi-ted the proliferation of LSCC cells (P<0.05) .The transwell assay confirmed that knockdown of CXCL8 also significantly inhibited the migration and invasion of FD-LSC-1 cell (average inhibition rate was 40.0％,38.5％,respectively);Knockdown of CXCL8 also significantly inhibited the migration and inva-sion of AMC-HN8 cell (average inhibition rate was 37.5％,53.5％,respectively ) .The analysis of bioinformatics predicted that CXCL8 may be a target of miR-513b-5p.The dual luciferase reporter assay confirmed that miR-513b-5p could bind to the CXCL8-3'UTR.QRT-PCR assay also confirmed that over-expression of miR-513b-5p could decrease the 60％ of the CXCL8 expression (P<0.01) .Cell function rescue assays found that overexpressed of CXCL8 could effectively reversed proliferation,migration and invasion of LSCC cells weakened by miR-513b-5p (P<0.05) .In summary,miR-513b-5p inhibited the proliferation,migration and invasion of LSCC cells by targeting CXCL8.

Objective:To explore the optimal storage condition and time of umbilical cord blood from collection to preparation.Methods:Collect cord blood samples from 30 healthy newborns,with each new born's umbilical cord blood was divided into two parts on average.One part was stored in cold storage(4 ℃)and the other was stored at room temperature(20-24 ℃).Samples were taken at 24,36,48,60 and 72 h,respectively,total nucleated cells(TNC)count and TNC viability was analyzed.Flow cytometry was used to detect the ratio of viable CD34+cells to viable CD45+cells and viability of CD34+cells,and colony-forming unit-granulocyte-macrophage(CFU-GM)count was performed by hematopoietic progenitor cell colony culture.The change trend of each index over time was observed,and the differences in each index was compared between cold storage and room temperature storage under the same storage time.Results:The TNC count(r4℃=-0.9588,r20-24℃=-0.9790),TNC viability(r4℃=-0.9941,r20 24 ℃=-0.9970),CD34+cells viability(r4℃=-0.9932,r20-24℃=-0.9828)of cord blood stored in cold storage(4 ℃)and room temperature storage(20-24 ℃)showed a consistent downward trend with the prolongation of storage time.The percentage of viable CD34+cells(r4℃=0.9169,r20-24 ℃=0.7470)and CFU-GM count(r4℃=-0.2537,r20-24℃=-0.8098)did not show consistent trends.When the storage time was the same,the TNC count,TNC viability,CD34+cells viability and CFU-GM count of cord blood stored in cold storage were higher than those stored at room temperature.Under the same storage time(24,36,48,60 or 72 h),TNC viability in room temperature storage was significantly lower than that in cold storage(P＜0.001),but TNC count,percentage of viable CD34+cells and CFU-GM count were not significantly different between room temperature storage and cold storage.When stored at room temperature for 24 h and 36 h,the viability of CD34+cells was significantly lower than that in cold storage(P＜0.001,P＜0.01),when the storage time for 48,60 and 72 h,there was no significant difference in the CD34+cells viability between room temperature storage and cold storage.Conclusion:It is recommended that cord blood be stored in cold storage(4 ℃)from collection to preparation,and processed as soon as possible.

Objective:To investigate the risk factors of pulmonary infection in patients with acute leukemia(AL)after chemotherapy.Methods:A total of 294 patients with AL were collected and divided into infection group(n=93)and control group(n=201)according to whether the pulmonary infection occurred after chemotherapy.Analyze the correlation between sociodemographic data(sex,age,BMI),clinical data(disease type,ECOG score,invasive procedure,underlying disease,hormone therapy,empirical use of antibiotics,prognosis stratification,chemotherapy intensity,primitive cell count,white blood cell count,neutrophil count,duration of granulocyte deficiency,platelet count,hemoglobin,and albumin and pulmonary infection after chemotherapy.COX regression method was used to analyze the risk factors of pulmonary infection in AL patients after chemotherapy.Results:Among 294 patients with AL,11 died within 30 days after pulmonary infection.There were statistically significant differences in age,smoking history,ECOG score,invasive procedure,hormone therapy,empirical use of antibiotics,prognosis stratification,chemotherapy intensity,primitive cell count,neutrophil count,duration of granulocyte deficiency,platelet count,hemoglobin,albumin and fasting blood glucose between the 2 groups(P＜0.05).COX regression analysis showed that smoking history,invasive procedure,unexperienced use of antibiotics,poor prognosis,long duration of granulocytopenia,low platelet level and low albumin were high risk factors for pulmonary infection in AL patients after chemotherapy(P＜0.05).Conclusion:Smoking,invasive procedures,unexperienced use of antibiotics,poor prognosis,long duration of granulodeficiency,low platelet levels and low albumin are risk factors for pulmonary infection in AL patients after chemotherapy.

Multiple myeloma(MM)is an incurable malignant plasma cell diseases,the incidence of which is increasing year by year.The application of immunomodulators drugs,proteasome inhibitors,anti-CD38 antibodies,CAR-T,and HSCT have significantly improved the prognosis of patients with MM,however new therapeutic tools need to be developed to improve the prognosis of patients with relapsed/refractory after conventional regimens treatment.Bispecific antibodies are a novel immunotherapeutic approach that generates immune synapses by binding to targets on malignant plasma cells and cytotoxic immune effector cells(T cells/natural killer cells),leading to T/NK cells activation and malignant plasma cell lysis.Several preclinical and phase Ⅰ clinical studies have shown good efficacy,bringing new possibilities for patients with relapsed/refractory MM to improve their prognosis in the future in combination with the rest of the treatment options.This article summarizes the classification of bispecific antibodies developed in recent years,and the results of preclinical and clinical trials,which will provide some reference for treating MM.

Objective:To investigate the clinical characteristics and treatment of relapsed CD5+diffuse large B-cell lymphoma(DLBCL).Methods:The data of a patient with CD5+DLBCL was collected,and its clinical characteristics and treatment outcome were analyzed.Results:The patient developed hemophagocytic syndrome and achieved complete remission(CR)after 6 cycles of R-ECHOP chemotherapy,then relapsed.After 2 cycles of PD-1 inhibitor combined with lenalidomide treatment,the patient achieved CR again accompanied by a decrease of interleukin(IL)-10 expression level.After a total of 15 cycles of chemotherapy,the patient remained in CR for 24 months,and the level of IL-10 remained in the normal range.Conclusion:PD-1 inhibitor combined with lenalidomide regimen may be a new treatment for relapsed CD5+DLBCL.

Objective:To investigate the effect of feeder layer cells expressing interleukin(IL)-21 on the amplification of NK cells in vitro.Methods:The K562 cell line with IL-21 expression on its membrane was constructed by electroporation,and co-cultured with NK cells after inactivation.The proliferation of NK cells was observed.The killing function of the amplified NK cells in vitro was evaluated by the lactate dehydrogenase(LDH)and interferon-γ(IFN-y)release assay.A colorectal cancer xenograft model in NOD/SCID mice was established,and a blank control group,a NK cell group and an amplified NK cell group were set up to detect the tumor killing effect of amplified NK cells in vivo.Results:K562 cells expressing IL-21 on the membrane were successfully constructed by electroporation.After co-culturing with K562 cells expressing IL-21 on the membrane for 17 days,the NK cells increased to 700 times,which showed an enhanced amplification ability compared with control group(P＜0.001).In the tumor cell killing experiment in vitro,there was no significant difference in the killing activity on tumor cells between NK cells and amplified NK cells,and there was also no significant difference in mice in vivo.Conclusion:K562 cells expressing IL-21 on the membrane can significantly increase the amplification ability of NK cells in vitro,but do not affect the killing function of NK cells in vitro and in vivo.It can be used for the subsequent large-scale production of NK cells in vitro.
