Serotonin-selective reuptake inhibitors （SSRIs）， as widely used antidepressants in clinical practice， exhibit significant individual differences in antidepressant efficacy. Gut microbiota plays an important role in the development and progression of depression， and the use of SSRIs exerts a significant impact on the gut microbiota of patients with depression. Based on this， this article reviews the research progress on the interactions between the antidepressant effects of SSRIs and gut microbiota. It has been found that SSRIs can influence the diversity， abundance， and function of the gut microbiota directly or indirectly. Conversely， the composition of the gut microbiota and differences in its functional metabolic pathways， and other factors， can in turn affect the antidepressant effects of SSRIs. Therefore， in clinical practice， gut microbiota diversity can be utilized as a predictive indicator for the antidepressant effects of SSRIs. Probiotics can be employed as an adjunct therapy alongside SSRIs， and dietary adjustments， as well as fecal microbiota transplantation， can be used to enhance the therapeutic efficacy of SSRIs. In the future， large-scale， multicenter clinical studies should be conducted， enrolling a broadly representative cohort of patients with depression， to uncover the true association between the antidepressant effects of SSRIs and gut microbiota， thereby opening up more effective avenues for the comprehensive treatment of depression.

Objective To investigate the expression of HOXB4 gene in patients with myelodysplastic syn-dromes(MDS)and its clinical significance in disease progression.Methods mRNA expression of HOXB4 gene in bone marrow mononuclear cells was detected by real-time fluorescence quantitative PCR(RT-qPCR),and the difference in HOXB4 expression was compared between 49 patients with MDS(MDS group)and 35 patients without MDS(group C).The relationship of mRNA expression of HOXB4 with disease characteristics and clinical prognosis was explored in MDS patients.Results mRNA expression level of HOXB4 gene was higher in MDS group than that in group C(P＜0.05).The patients were divided into a high-and a low-expression group according to the median expression level of HOXB4.Leukocyte count was lower in the high-expression group in the low-expression group at the time of initial diagnosis.The proportion of patients with subtypes of primitive cellular hyperplasia,poor prognostic staging and leukemic transformation was higher in the high-expression group than in the low-expression group.Conclusions mRNA expression level of HOXB4 gene has certain relation with AML transformation in MDS patients.

Objective To explore the association of the magnitude of systolic blood pressure reduction(SBPr)with post-procedure 24 h symptomatic intracranial hemorrhage(sICH)and 90-day clinical outcomes in patients with successful endovascular thrombectomy(EVT).Methods Consecutively registered patients with EVT caused by anterior circulation large vessel occlusion stroke(LVOS)in the First Affiliated Hospital of Wannan Medical College(Yijishan Hospital)between July 2015 and April 2023 and patients with successful reperfusion were analyzed.Demographic data,medical history(hypertension,diabetes),the trial of Org 10172 in acute stroke treatment(TOAST)classification,the baseline National Institutes of Health Stroke Scale(NIHSS)score and the baseline Alberta stroke early CT(ASPECT)score of patients were collected.And procedure related parameters(including time from onset to puncture,time from onset to reperfusion,occluded site[internal carotid artery,M1 segment of middle cerebral artery,M2 segment of middle cerebral artery],collateral circulation status[determined based on preoperative occluded angiography showing the range of collateral circulation in the occluded vessel area,defined as good collateral circulation with a reflux range of ≥ 50％and poor collateral circulation with a reflux range of＜50％]),immediate postoperative reperfusion status(evaluated using the modified thrombolysis for cerebral infarction[mTICI]grading,successful reperfusion defined as mTICI grading of 2b-3),24 hours sICH,and 90 days clinical outcomes(evaluated using the modified Rankin scale score at 90days after EVT,with a score ≤ 2indicating a good prognosis and a score＞2indicating a poor prognosis).SBPr was defined as(baseline SBP-mean SBP)/baseline SBP x 100％.According to the the magnitude of SBPr,SBPr is divided into 5 categories(＜-10％,-10％-10％,＞10％-20％,＞20％-30％and＞30％).Based on the clinical outcomes at 90 days and the occurrence of sICH at 24 hours after EVT,patients were divided into a good prognosis group and a poor prognosis group,as well as an sICH group and a non-sICH group.The relationship between SBPr and postoperative 90 days clinical prognosis or sICH was analyzed using a binary Logistic regression model.Subgroup analysis was conducted based on a history of hypertension(yes and no),continuous intravenous hypotensive therapy(yes and no),baseline ASPECT scores(3-5 and 6-10),and collateral circulation status(good and bad).Using a restricted cubic plot to depict the relationship between SBPr and sICH and clinical prognosis at 90days.Results(1)In total,731 patients were included.The median age was 71(62,77)years and 424(58.0％)were men.The median baseline NIHSS score was 14(12,18),the median baseline ASPECT was 9(7,10),405(55.4％)patients achieved 90-day modified Rankin scale score 0-2,and 35 patients(4.8％)developed sICH.(2)Multivariate analysis showed that the older age(OR,1.036,95％CI 1.017-1.056),the higher baseline NIHSS score(OR,1.095,95％CI1.049-1.144),the lower baseline ASPECT score(OR,0.704,95％CI 0.636-0.780),diabetes(OR,1.729,95％CI 1.084-2.758),bad collateral circulation(good collateral circulation vs.bad collateral circulation,OR,0.481,95％CI 0.332-0.696)and SBPr＞30％(SBPr-10％-10％as a reference,OR,2.238,95％CI 1.230-4.071),the higher the risk of poor clinical outcomes at 90 days(all P＜0.05).Continuous intravenous hypotensive therapy is a risk factor for postoperative 24 h sICH(OR,2.278,95％CI 1.047-4.953;P=0.038),while SBPr 20％-30％is associated with a lower risk of postoperative 24 h sICH(SBPr-10％-10％as a reference,OR,0.362,95％CI0.131-0.998;P=0.049).(3)The restrictive cube plot shows that there is a U-shaped relationship between SBPr after EVT and poor clinical outcomes at 90 days,while there is a nearly linear relationship with the occurrence of sICH.The more SBP reduction,the lower the incidence of sICH.(4)In the subgroup analyses,in the non-hypertension history and the good collateral circulation group,SBPr＞30％has a higher risk of poor clinical outcomes compared to SBPr-10％-10％(OR and 95％CI were 2.921[1.000-8.528]and 2.363[1.078-5.183],respectively,with P=0.05 or P＜0.05);After EVT,the group receiving continuous intravenous hypotensive therapy and the baseline ASPECT score 6-10 groups showed a significant correlation between SBPr＞30％and poor clinical outcomes at 90 days(SBPr-10％-10％as a reference,OR and 95％CI were 2.646[1.168-5.993]and 2.481[1.360-4.527],respectively,with P＜0.05).The correlation between SBPr and lower incidence of sICH was only found in the subgroup of poor collateral circulation(SBPr-10％-10％as a reference,SBPr＞20％-30％:OR,0.133,95％CI 0.027-0.652;SBPr＞30％:OR,0.104,95％CI 0.013-0.864;all P＜0.05).Conclusions Among patients who achieved successful reperfusion with EVT,SBPr might be related to a worse functional outcome at 90 days and sICH 24 h after operation.However,the relationship may exhibit significant heterogeneity across different subgroups.Baseline ASPECT score,history of hypertension,collateral circulation,and the use of continuous venous hypertension after EVT have been highlighted in individualized blood pressure management after EVT.

Objective To investigate the expression level of tetratricopeptide repeat protein 9A in tumors and its association with the patients'prognosis and immune infiltration.Methods TTC9A expression in different tumor tissues and its association with prognosis,DNA methylation,tumor mutation burden(TMB),and microsatellite instability(MSI)were analyzed based on data from TCGA and GTEx.TIMER and xCell were used to analyze the relationship between TTC9A expression and immune infiltration.Western blotting and RT-qPCR were used to detect the expression of TTC9A in 4 types of cancer cell lines.Results TTC9A expressions were significantly increased in many tumors and down-regulated in a few cancer types(P<0.05).Western blotting and RT-qPCR showed that TTC9A expressions were elevated in lung,colon and liver cancer cells but decreased in bladder cancer cells.In head and neck squamous cell carcinoma,renal clear cell carcinoma,renal papillary cell carcinoma,low-grade glioma,malignant mesothelioma,and endometrial carcinoma tumors,a high expression of TTC9A was strongly correlated with better overall survival(OS),disease-specific survival(DSS),and progression-free interval(PFI)(P<0.05),but was correlated with worse OS,DSS,and PFI in lung adenocarcinoma,pancreatic adenocarcinoma,adrenal carcinoma,and rectal adenocarcinoma(P<0.05).TTC9A hypermethylation was associated with a more favorable prognosis of glioblastoma multiforme,low-grade glioma,uveal melanoma,and ovarian plasmacytoid cystadenocarcinoma(P<0.05)but with poor prognosis of squamous cell carcinoma of the uterine cervix and intracervical adenocarcinoma,squamous cell carcinoma of head and neck,squamous cell carcinoma of the lungs,adrenal carcinoma,and endometrial carcinoma(P<0.05).In most of the cancer types,TTC9A was significantly correlated with the level of immune cell infiltration(P<0.05).Conclusion TTC9A can be used as a prognostic marker for a variety of cancers and is strongly associated with TBM,MSI and immune cell infiltration.

Objective To investigate the influencing factors for acute multiple vessels occlusion(MVO)and its impact on the prognosis of patients with anterior circulation acute large vessel occlusion stroke(ALVOS)who achieved successful recanalization after endovascular treatment(EVT).Methods Patients with anterior circulation ALVOS who received successful EVT at the Yijishan Hospital of Wannan Medical College between July 2015 and April 2023 were retrospectively analyzed.Baseline data,including age,sex,onset-to-puncture time(OTP),onset-to-recanalization time(OTR),medical history(including atrial fibrillation,diabetes,hypertension),alcohol and smoking history,admission blood pressure(systolic and diastolic),Alberta stroke program early CT score(ASPECTS),National Institutes of Health stroke scale(NIHSS)score,trial of Org 10172 in acute stroke treatment(TOAST)classification(atherosclerotic type,cardioembolic type,and other etiology types),and 90-day modified Rankin scale(mRS)score were collected.Collateral circulation was assessed based on the degree of contrast agent reflux observed in the occluded arterial supply area during delayed DSA,and patients were classified into poor and good collateral circulation groups.Malignant cerebral edema was defined as a midline shift of ≥5 mm on the follow-up CT scan performed on day 3 post-surgery.The primary endpoint(efficacy indicator)was the 90-day mRS score,with mRS score≤ 2 considered as a good prognosis and mRS score＞2 considered as a poor prognosis.The secondary endpoint(safety indicator)was the 90-day mortality rate.All patients were divided into MVO and non-MVO groups based on whether they had single or multiple intracranial vessel occlusions.Acute MVO was defined as the detection of acute occlusion of other large or medium vessels,in addition to the main vessels(internal carotid artery or M1/M2 segments of the middle crebral artery[MCA]),in CT angiography,MR angiography,or DSA,resulting in ischemia in brain regions distinct from the main occlusion area.Factors that showed statistically significant differences in univariate analysis were further analyzed using multivariate Logistic regression to identify the risk factors for the occurrence of acute MVO and the factors associated with the prognosis of ALVOS patients.Results A total of 846 patients with ALVOS were included,with ages ranging from 26 to 94 years(mean age[69±11]years).The proportion of male patients was 57.2％(484/846).The median admission ASPECTS was 8(7,9)and the median admission NIHSS score was 14(12,18).The incidence of malignant cerebral edema at 3 days post-surgery was 13.4％(112/835),and the 90-day mortality rate was 19.1％(162/846).(1)Among the 846 ALVOS patients,810(95.7％)were in the non-MVO group and 36(4.3％)were in the MVO group.Univariate analysis showed significant differences between the MVO and non-MVO groups in terms of atrial fibrillation,malignant cerebral edema,admission ASPECTS,admission NIHSS scores,TOAST classification,collateral circulation,rate of complete recanalization,and 90-day poor prognosis rate(all P＜0.05).However,there was no statistically significant difference in 90-day mortality between the two groups(P=0.193).Multivariate Logistic regression analysis showed that TOAST classification of cardioembolic type(OR,16.089,95％CI 1.835-141.061,P=0.012)and other etiology types(OR,9.768,95％CI 1.078-88.540,P=0.043)were associated with the occurrence of MVO.(2)Among the 846 ALVOS patients,445 had a good prognosis at 90days,and 401 had a poor prognosis.Univariate analysis showed that,compared to the good prognosis group,the poor prognosis group had a lower proportion of males and smokers,and a higher proportion of patients with older age,higher baseline systolic blood pressure,hypertension,diabetes,and atrial fibrillation(all P＜0.01).Additionally,the poor prognosis group had higher admission NIHSS scores(P＜0.01),lower admission ASPECTS,lower rates of good collateral circulation and complete recanalization,higher rates of malignant cerebral edema and MVO,and statistically significant differences in TOAST classification distribution(all P＜0.01).Multivariate Logistic regression analysis showed that MVO was associated with poor 90-day prognosis in ALVOS patients after EVT(OR,3.368,95％CI 1.149-9.878,P=0.027).Furthermore,older age(OR,1.045,95％CI 1.025-1.066),diabetes(OR,1.719,95％CI 1.080-2.734),higher baseline systolic blood pressure(OR,1.012,95％CI 1.004-1.019),lower admission ASPECTS(OR,0.746,95％CI 0.674-0.826),higher admission NIHSS score(OR,1.115,95％CI 1.070-1.162),without immediate postoperative complete recanalization(OR,0.413,95％CI 0.290-0.592),poor collateral circulation(OR,0.594,95％CI 0.415-0.851),and malignant cerebral edema(OR,6.191,95％CI 3.026-12.670)were all associated with poor 90-day prognosis after EVT in ALVOS patients(all P＜0.05).Conclusions The TOAST classification of cardioembolic type and other etiology types is associated with MVO.MVO is a risk factor for poor outcomes after successful EVT in ALVOS patients.

Objective:To analyze the role of dandelion and mulberry leaf in the progression of acute myeloid leukemia(AML)by network pharmacology,and to clarify the active components and their mechanisms in treating AML.Methods:The active components of dandelion and mulberry leaf were screened by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP).The targets were predicted by SwissTargetPrediction Database.The AML-related genes and protein targets were retrieved from the SymMap Database,the GeneCards Human Gene Database,the DisGeNET Database,and the Online Mendelian Inheritance in Man(OMIM)Database.The AML-related genes and target genes of dandelion and mulberry leaf were compared by comparative analysis and were identify by the enrichment genes,followed by Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis.The drug-active component-target network and protein-protein interaction(PPI)network were constructed by Cytoscape 3.8.0 software,and the core genes were selected by CytoNCA plugin;the molecular docking was conducted by AutoDock software.Results:After filtering by databases,39 active components were identified,and 148 common targets between dandelion-mulberry leaf and AML were collected.The GO functional enrichment analysis mainly involved cytokine-mediated signaling pathways,positive regulation of kinase activity,and oxidative stress responses.The KEGG signaling pathway enrichment analysis focused on the phosphatidylinositol 3 kinase/protein kinase B(PI3K-AKT)signaling pathway,the tumor necrosis factor(TNF)signaling pathway,and the Janus kinase/signal transducer and activator of transcription(JAK-STAT)signaling pathway.The key targets were identified by topological analysis including signal transducer and activator of transcription 3(STAT3),epidermal growth factor receptor(EGFR),protein kinase B1(AKT1),recombinant human epidermal growth factor(EGF),vascular endothelial growth factor A(VEGFA),oncogene MYC,tumor protein P53(TP53),mitogen-activated protein kinase 3(MAPK3),cysteiny asparate specific protease-3(CASP3),oncogene SRC,heat shock protein 90 alpha family class A member 1(HSP90AA1),tenascin XB1(CTNNB1),phosphoinositide kinase-3 catalytic subunit alpha(PIK3CA),interleukin 6(IL-6),TNF,mitogen-activated protein kinase 1(MAPK1),and phosphatidylinositide kinase-3 regulatory subunit 1(PIK3R1).The molecular docking results showed the highest affinity pairing to be taraxerol with MYC(-8.74 kcal·mol-1),and quercetin,kaempferol,luteolin,and artemetin demonstrated good binding affinities with various targets.Conclusion:The main active components of dandelion-mulberry leaf,such as quercetin,taraxerol,kaempferol,luteolin,and artemetin,may exert the anti-AML effect by regulating AKT1,STAT3,HSP90AA1,IL-6,and MAPK1;regulation the PI3K-AKT signaling pathway may be the critical mechanism of anti-AML effect by dandelion-mulberry leaf.

To improve the transduction efficiency of recombinant adeno-associated virus (rAAV) in NK92 cells, the number of cells, concentration of IL-2 in the medium, and serotype and dosage of rAAV were explored to optimize cell state and viral transfection conditions.Then, zinc chloride (ZnCl2), chloroquine, polyvinyl alcohol (PVA) and genistein with different concentration were added separately during transfection to further improve the viral transduction efficiency.The results showed that, at cell number of 5 × 105, the expression efficiency of enhanced green fluorescent protein (EGFP) was relatively high.When the IL-2 concentration was 1 000 IU/mL, NK92 cells were most suitable for virus transfection. The transduction efficiency of different serotypes of rAAV in NK92 cells was rAAV6, rAAV2 and rAAV9 in descending order.Pretreatment of NK92 cells with genistein could significantly increase the viral transduction efficiency, while the addition of other reagents had no significant effect.Through the optimization of the above conditions, the transduction efficiency of rAAV to NK92 cells could be significantly improved, which provided evidence for functional genetic modification of NK92 cells by rAAV.
