OBJECTIVE To investigate the causal relationships between gut microbiota, blood metabolites and antidepressant treatment response from a genetic perspective, and to assess the potential mediating role of blood metabolites. METHODS This study utilized a two-sample Mendelian randomization (MR) design. Exposure data were derived from four large-scale gut microbiome genome-wide association study (GWAS) datasets and two blood metabolite GWAS datasets. The inverse variance weighted method was used as the primary method to evaluate the causal relationships between gut microbiota, blood metabolites and antidepressant effects. The robustness, heterogeneity and horizontal pleiotropy of the results were evaluated through various sensitivity analyses. Additionally, the false discovery rate (FDR) was applied to correct type Ⅰ errors caused by multiple hypothesis testing. Finally, MR mediation analysis was conducted to test the potential mediating effect of blood metabolites. RESULTS The s_ Bilophila was negatively associated with the effectiveness of antidepressant treatment ( P =8.030×10 -5 , then P =0.033 after FDR correction), and the f_Bacteroidales was positively associated with the effectiveness of antidepressant treatment ( P =3.275×10 -4 , then P =0.034 after FDR correction). Over a hundred blood metabolites were also screened out as being associated with antidepressant response, but after FDR correction, no significant causal relationship was observed. The P value of the mediation effect proportion of blood metabolites in the “gut microbiota-blood metabolites-antidepressant efficacy” pathway was greater than 0.05. CONCLUSIONS The s_ Bilophila may represent a risk factor for antidepressant effects, whereas the f_Bacteroidales may serve as a protective factor for antidepressant effects. The correlation between blood metabolites and antidepressant efficacy is not strong, and no genetic evidence is found to support that the investigated blood metabolites play a key mediating role between the gut microbiota and antidepressant response.

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 evaluate the relationship between microRNA-29a (miR-29a) and p53 up-regulated modulator of apoptosis (PUMA) in propofol-induced reduction of glucose deprivation (GD)-induced injury to human glioma cells.Methods:Human glioma U87 cells were cultured in vitro to the logarithmic growth phase. Cells were then divided into 6 groups ( n=24 each) by the random number table method: control group (group C), group GD, propofol + GD group (group P+ GD), miR-29a inhibitor group (group I), miR-29a inhibitor + GD group (group I+ GD) and miR-29a inhibitor+ propofol+ GD group (group I+ P+ GD). Cells were cultured in normal condition in group C. The culture medium was changed to glucose-free DMEM solution, and the cells were cultured for 12 h in group GD. In group P+ GD, cells were incubated with propofol 10 μmol/L for 12 h and then incubated in glucose-free DMEM solution for 12 h. In group I, group I+ GD and group I+ P+ GD, miR-29a inhibitor was transfected into cells using lipofectamine transfection kit, and then the cells were cultured for 48 h, and the other treatments were similar to those previously described in group P+ GD. The cell survival rate, mitochondrial membrane potential and level of reactive oxygen species (ROS) were determined. The expression of miR-29a was detected by quantitative real-time polymerase chain reaction, and the expression PUMA was detected by Western blot. Results:Compared with group C, the cell survival rate and mitochondrial membrane potential were significantly decreased, the level of ROS was increased, the expression of miR-29a was down-regulated, and the expression of PUMA was up-regulated in group GD and group I ( P<0.05). Compared with group GD, the cell survival rate and mitochondrial membrane potential were significantly increased, the level of ROS was decreased, the expression of miR-29a was up-regulated, and the expression of PUMA was down-regulated in group P+ GD, and the cell survival rate and mitochondrial membrane potential were significantly decreased, the level of ROS was increased, the expression of miR-29a was down-regulated, and the expression of PUMA was up-regulated in group I+ GD ( P<0.05). Compared with group P+ GD, the cell survival rate and mitochondrial membrane potential were significantly decreased, the level of ROS was increased, the expression of miR-29a was down-regulated, and the expression of PUMA was up-regulated in group I+ P+ GD ( P<0.05). Conclusions:The mechanism by which propofol reduces glucose deprivation-induced injury to human glioma cells is related to up-regulation of miR-29a expression and down-regulation of PUMA expression.

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.
