Objective:To investigate the alterations in the brain structural network properties related to cognitive emotion regulation strategies in young, first-episode and drug-naive (FEDN) patients with major depressive disorder (MDD).Methods:One hundred and twelve young patients who were diagnosed with FEDN MDD were enrolled in the Second Xiangya Hospital of Central South University between October 2019 and October 2023, and 143 healthy controls (HC) were recruited for reference during the same period. Clinical data and T 1 structural images of high-resolution magnetic resonance imaging were collected from all participants, and the cognitive emotion regulation was assessed using the Chinese version of the Cognitive Emotion Regulation Questionnaire (CERQ-C). The brain structural alterations related to cognitive emotion regulation strategies were explored using whole-brain voxel-based morphometry (VBM) group analysis and individual differential structural covariance network (IDSCN) analysis. Partial correlation analysis was performed between the IDSCN anomalous structural concatenated edge and subdimensions of the CERQ-C. Results:The scores on the sub-dimension of negative cognitive emotion regulation (self-condemnation, rumination, catastrophization, blaming others) in the young FEDN MDD patients in CERQ-C were significantly higher than those in HC (14.28±2.30 vs 12.45±2.00, t=6.501, P<0.001;14.40±2.97 vs 11.31±2.93, t=7.934, P<0.001;12.19±3.75 vs 7.59±2.58, t=10.553, P<0.001;10.26±3.00 vs 8.74±2.89, t=3.916, P<0.001; respectively). There was no statistically significant difference in the VBM group analysis (all P>0.05). However, IDSCN single sample t test results showed significant group differences between the left orbitofrontal inferior gyrus and the left supplementary motor area, the left orbitofrontal middle gyrus and the bilateral precuneus, and the left superior temporal gyrus and the bilateral hippocampus (all P<0.05). With controlling for age, sex, and other factors, partial correlation analysis results showed that the left orbital inferior frontal gyrus-left supplementary motor area connection in patients with MDD was positively correlated with the self-condemnation and acceptance scores of the CERQ-C ( r=0.226, P=0.027; r=0.216, P=0.035), while negatively correlated with the score of blaming others ( r=-0.252, P=0.013). Additionally, connections between the right hippocampus and left superior temporal gyrus were significantly associated with the scores on catastrophization subdimension of the CERQ-C ( r=0.229, P=0.025). Conclusion:Due to its sensitivity to individualized analyses, the IDSCN analysis found that abnormal topological property changes were mainly manifested in the limbic system, the sensorimotor system, and the default network in young FEDN MDD patients, and were linked to their negative cognitive emotion regulation strategies, even though the VBM group analysis did not yield any significant results.

Sodium glucose cotransporter(SGLT)2 inhibitors,initially developed as antihyperglycemic agents,have demonstrated remarkable cardioprotective effects in numerous clinical trials and are now utilized in the treat-ment of heart failure across a range of ejection fractions.SGLT2 is predominantly expressed in the renal proximal tubules,brain,and epicardial adipose tissue within the human body.Research indicates that the protective effects of SGLT2 inhibi-tors in heart failure are linked to their direct modulation of SGLT2 receptors in both the kidneys and epicardial adipose tis-sue.Furthermore,SGLT is also present in the brain,and recent studies have revealed that SGLT2 inhibitors can enhance sympathetic activity in patients with metabolic syndrome,suggesting a potential neuroregulatory role.Given that excessive activation of the sympathetic nervous system can contribute to the onset and progression of heart failure,this paper reviews the neural regulatory mechanisms of SGLT2 inhibitors to provide insights for a deeper understanding of heart failure and to optimize their clinical application.

Objective:To evaluate the extracorporeal membrane oxygenation (ECMO) related outcomes during hospitalization during the intensive care unit (ICU) in idiopathic pulmonary fibrosis (IPF) patients with high body mass index (BMI, >25 kg/m 2) undergoing lung transplantation with ECMO support. Methods:A retrospective observational study was conducted. IPF patients who received ECMO during lung transplantation admitted to the Affiliated Wuxi People's Hospital of Nanjing Medical University from 2019 to 2020 were enrolled. Preoperative indicators including, demographics, comorbidities, arterial blood gas, and laboratory indicators; intraoperative indicators, such as lung lobe volume reduction, surgical type, surgical time, cold ischemia time, blood loss and transfusion volume; immediate indicators upon admission to the ICU, such as blood gas analysis and laboratory indicators; ECMO related outcomes, such as ECMO mode, ECMO support time, ECMO related complications (bleeding at the catheterization site, intraductal thrombosis, lower limb ischemia), and the length of ICU stay, duration of mechanical ventilation, and 30-day survival rate were collected. According to BMI, patients were divided into three groups: light weight group (BMI < 18.5 kg/m 2), normal weight group (BMI 18.5-24.9 kg/m 2), and overweight group (BMI ≥ 25.0 kg/m 2). Mainly to compare the relevant outcomes of ECMO among patients during ICU. Results:A total of 114 IPF patients who received ECMO support during lung transplantation were collected, including 23 cases in the light weight group, 63 cases in the normal weight group, and 28 cases in the overweight group. Compared with patients with underweight and normal weight, overweight patients were more likely to have hypertension (46.4% vs. 8.7%, 23.8%, P < 0.01) and coronary heart disease (32.1% vs. 4.3%, 20.6%, P < 0.05) before surgery, which was consistent with international guidelines for obesity. Other clinical data (preoperative, intraoperative, ICU characteristics) showed no statistically significant differences and were comparable. There was no statistically significant difference in terms of ECMO related outcomes, such as ECMO related complications [veno-venous (V-V) mode: 78.3%, 77.8%, 78.6%, veno-arterial (V-A) mode: 21.7%, 22.2%, 21.4%], ECMO support time (hours: 61.70±20.03, 44.57±5.76, 41.77±7.26), ECMO related complications (bleeding at the catheterization site: 4.3%, 7.9%, 14.3%; intraductal thrombosis: 8.7%, 12.7%, 17.9%; lower limb ischemia: 8.7%, 12.7%, 14.3%), and the length of ICU stay (days: 11±3, 7±1, 9±1), duration of mechanical ventilation [days: 2 (2, 11), 2 (2, 6), 3 (2, 8)] among the light weight group, normal weight group, and overweight group (all P > 0.05). Kaplan-Meier survival curve analysis showed that there was no statistically significant difference in the 30-day cumulative survival rate among the three groups (Log-Rank test: χ2 = 0.919, P = 0.632). Conclusions:High BMI does not worsen ECMO-related outcomes or adversely affect early prognosis in IPF patients undergoing lung transplantation. BMI as a single parameter should not be a contraindication for the use of ECMO in lung transplantation surgery for IPF patients.

Objective To assess effect of ultrasound-guided erector spinae plane block(ESPB)combined with patient controlled intravenous analgesia(PCIA)on postoperative analgesia after cesarean section.Methods A total of 120 full-term singleton pregnant women who underwent cesarean section under spinal anesthesia at Jiaxing Maternal and Child Health Care Hospital from May 2022 to August 2023 were selected.Participants were randomly divided into three groups using a random number table:Group E(ESPB combined with PCIA),group T[transversus abdominis plane(TAP)block combined with PCIA],and control group(PCIA alone),with 40 women in each group.Visual analogue scale(VAS)and Bruggrmann comfort scale(BCS)scores during rest and coughing were recorded at 4h,8h,12h,24h,and 48h postoperatively.Number of effective PCIA presses,total sufentanil dosage,proportion of rescue analgesia and maternal satisfaction were also documented within 48h.Additionally,adverse reactions and neonatal outcomes were observed within the same 48h period.Results Postoperatively,VAS scores for rest and coughing in group E at 8h,12h,24h were significantly lower than those in group T,those in two groups were lower than those in control group(P＜0.05).Postoperatively at 8h,12h,and 24h,BCS scores in group E were significantly higher than those in group T,with both higher than those in control group(P＜0.05).Within 48h after surgery,the number of effective PCIA presses,proportion of rescue analgesia and total sufentanil dosage in group E were lower than those in group T,both lower than those in control(P＜0.05).Moreover,maternal satisfaction score in group E was significantly higher than that in group T,that in two groups was significantly higher than that in control group(P＜0.05).Within 48h after surgery,there were no significant differences in adverse reactions or neonatal outcomes among the three groups(P＞0.05).Conclusion Ultrasound-guided ESPB combined with PCIA outperforms TAP block combined with PCIA,with reducing analgesic dose and enhancing maternal satisfaction and comfort.

AIM:To explore the effect of tomatidine(TA)on lipopolysaccharide(LPS)-induced nerve cell in-jury and the underlying mechanism.METHODS:The neuroinflammation model was induced by treating SH-SY5Y cells with LPS.These cells were divided into control(CON),LPS,and LPS+TA groups.The LPS group was treated with 5 μg/mL LPS for 24 h to establish an inflammatory model.The LPS+TA group was first treated with 5 μmol/L tomatidine for 24 h and then co-cultured with 5 μg/mL LPS for 24 h.Cell viability was detected using the CCK-8 assay.RT-qPCR was used to detect the mRNA expression of inflammatory factors tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β).The protein expression of transcription factor EB(TFEB),p-TFEB,P62,and microtubule-associated protein 1 light chain 3(LC3)expression was detected through Western blot.TFEB localization and cleaved caspase-3 expression were detected through immunofluorescence.The cell apoptosis rate was detected through flow cytometry.RESULTS:(1)Compared with the CON group,the LPS group exhibited significant increases in IL-1β and TNF-α mRNA levels(P＜0.05),the cell apoptosis rate,and the p-TFEB level(P＜0.01).By contrast,P62,LC3-Ⅱ/LC3-Ⅰ,and TFEB protein ex-pression levels decreased significantly(P＜0.05),and TFEB was mainly localized in the cytoplasm.(2)Compared with the LPS group,tomatidine treatment significantly decreased the p-TFEB protein expression level(P＜0.01),increased the TFEB protein expression level(P＜0.01),and promoted the TFEB protein to migrate into the nucleus.After treatment of tomatidine,the LC3-Ⅱ/LC3-Ⅰ protein expression level significantly increased(P＜0.05),and the cell apoptosis rate signifi-cantly decreased(P＜0.01).In addition,the TNF-α mRNA level significantly decreased after tomatidine treatment(P＜0.01).CONCLUSION:Tomatidine improves autophagy dysfunction,inflammatory reaction,and cell apoptosis induced by LPS via activating the transcription factor EB.

Objective:To investigate the synergistic effects and molecular mechanisms of dihydroartemisinin(DHA) and sorafenib(SOR) in inducing ferroptosis in anaplastic thyroid cancer(ATC) cells.Methods:CCK-8 and flow cytometry assays were performed to detect the effects of DHA and SOR on the proliferation and ferroptosis of ATC cells(CAL-62). Real-time fluorescence quantitative PCR and Western blotting assays were performed to detect the expressions of ferroptosis-related genes glutathione peroxidase 4(GPX4), solute carrier family 7 member 11 gene(SCL7A11), lipoxygenase-15(LOX-15), and p53. The levels of iron death intermediate metabolites including lactate dehydrogenase(LDH), glutathione(GSH), malondialdehyde(MDA), ferrous ion(Fe 2+ ), nitric oxide(NO), and reactive oxygen species(ROS)were measured by corresponding assay kits. The corresponding inhibition of DHA and SOR on ATC in vivo was analyzed in a tumor model in nude mice. Results:Compared with the control group, DHA, SOR, and DHA+ SOR treatment significantly inhibited cell proliferation and apoptosis in a dose-dependent manner( P<0.001), with increased LDH, Fe 2+, MDA, and ROS contents and reduced GSH activity( P<0.001), which were promoted by ferrous sulfate(FeSO 4)and reversed by ferroptosis inhibitor-1. Compared with the control group and the drug monotherapy group, 15-LOX-2 and p53 expressions were upregulated in DHA+ SOR group while GPX4 and SCL7A11 expressions were decreased( P<0.001), without significant difference in 15-LOX-1 protein content. In addition, NO level was significantly increased in DHA+ SOR group( P<0.001). DHA and SOR inhibited tumor growth of ATC in vivo. Conclusion:DHA and SOR synergistically induced ferroptosis via upregulating the expression of 15-LOX-2 gene and inhibiting NO synthesis in ATC cells.
