OBJECTIVE To investigate the effect of plasma trough concentration of venetoclax and its influencing factors in patients with acute myeloid leukemia （AML）. METHODS After 5 days of venetoclax administration， venous blood samples were collected from AML patients before the next dose. Plasma trough concentrations of venetoclax were determined using high-performance liquid chromatography-tandem mass spectrometry. Spearman correlation was used to assess the correlations between venetoclax plasma trough concentration and various parameters （including patients’ general information， venetoclax-related indicators， liver function indicators， kidney function indicators， and blood routine indicators）. Multiple linear regression analysis was performed to identify independent factors influencing plasma trough concentration of venetoclax. Using efficacy as dependent variable [complete remission （CR）+partial remission （PR） vs. no remission （NR）]， univariate and multivariate binary Logistic regression analyses were conducted to identify factors affecting efficacy. The receiver operating characteristic （ROC） curve was used to evaluate the predictive value of venetoclax plasma trough concentration for clinical efficacy （assessed as CR）. RESULTS A total of 172 venetoclax plasma trough concentration measurements from 101 patients were included in this study. The median plasma trough concentration of venetoclax was 2.38 （1.18， 3.85） μg/mL； the median sampling time for plasma trough concentration of venetoclax was 10 （7， 15） d； the duration of venetoclax use was （34±12） d. Multiple linear regression analysis showed that alkaline phosphatase （ B ＝14.65， 95%CI： 5.35-23.95， P ＝0.002）， total bilirubin （ B ＝－101.71， 95%CI： －197.16 to －6.25， P ＝0.037）， and white blood cell count （ B ＝－106.84， 95%CI： －187.61 to －26.07， P ＝0.010） were independent factors influencing plasma trough concentration of venetoclax. Due to patient attrition during treatment， 114 venetoclax plasma trough concentration measurements from 69 patients were included for efficacy evaluation. The results showed that 46 patients （66.7%） achieved CR， 11 patients （15.9%） achieved PR， and 12 patients （17.4%） were NR. Multivariate binary Logistic regression analysis showed that age， hemoglobin， venetoclax plasma trough concentration， hematocrit， and mean corpuscular hemoglobin were independent factors affecting patient efficacy （ P ＜0.05）. ROC curve analysis showed that the cut-off value of plasma trough concentration of venetoclax for predicting patient efficacy （assessed as CR） was 1.68 μg/mL （AUC＝0.66， 95%CI： 0.54-0.78， P ＝0.014）. CONCLUSIONS There is considerable inter-individual variability in plasma trough concentration of venetoclax among AML patients. Plasma trough concentration of venetoclax is significantly correlated with alkaline phosphatase， total bilirubin， and white blood cell count. Plasma trough concentration of venetoclax is an independent factor affecting patient’s efficacy， and when the cut-off value for predicting CR is above 1.68 μg/mL， better effects may be achieved.

Objective To evaluate the predictive value of triglyceride-glucose body mass index(TyG-BMI),atherogenic index of plasma(AIP),and postprandial glucose excursion(PPGE)for sarcopenia in patients with type 2 diabetes mellitus(T2DM).Methods An observational cohort trial was conducted on 590 hospitalized T2DM patients(322 males and 268 females)admitted to Department of Endocrinology of the First Affiliated Hospital of Chongqing Medical University between January 2023 and December 2024.General demographic data and key metabolic indicators,including fasting plasma glucose(FPG),postprandial 2-hour plasma glucose(PPG),triglyceride(TG)were collected,and then TyG-BMI,AIP,and PPGE were calculated.Based on the Asian Working Group for Sarcopenia(AWGS)2019 criteria,they were divided into a sarcopenia group(n=140)and a non-sarcopenia group(n=450).After 1∶1 propensity score matching(PSM),102 patients with sarcopenia were matched with 102 without.Differences in metabolic indicators FPG,PPG,TyG-BMI,AIP and PPGE were compared between the 2 groups.Spearman correlation analysis was conducted to assess correlations of these indicators with sarcopenia.Conditional logistic regression analysis was performed to identify independent risk factors,and receiver operating characteristic(ROC)curves were plotted to assess predictive performance.An external validation cohort consisting of 192 T2DM patients from Department of Endocrinology of Jiangbei Branch of First Affiliated Hospital of Army Medical University between January 2023 and December 2024 was included to validate the prediction model.Results After PSM,the baseline data of the 2 groups was balanced(P>0.05).The sarcopenia group showed higher levels of PPG,AIP,and PPGE,but lower TyG-BMI value than the non-sarcopenia group(all P=0.001).Spearman correlation analysis revealed that the TyG-BMI was negatively correlated(r=-0.404,P=0.001),whereas AIP and PPGE were positively correlated with concomitant sarcopenia(r=0.280,P=0.001;r=0.372,P=0.001)in the T2DM patients.Conditional logistic regression analysis identified AIP(OR=14.367)and PPGE(OR=1.245)as independent risk factors,while TyG-BMI(OR=0.966)as independent protective factors.ROC curve analysis revealed that the area under the curve(AUC)of the combined model of TyG-BMI,AIP and PPGE in predicting sarcopenia was 0.918,and the AUC value was 0.954 in external validation,with good sensitivity and specificity.Conclusion TyG-BMI,AIP,and PPGE are important metabolic predictors in T2DM patients with sarcopenia.Their combination has good screening value for sarcopenia,and can be applied in external prediction for T2DM patients.

In recent years,with the rapid development of mechanical thrombectomy(MT)for acute large vessel occlusion,an increasing number of clinical studies begin to focus on the acute distal medium vessel occlusion(DMVO).This article systematically reviews the existing literature,summarizes the definition and classification of DMVO,the advance in MT,the imaging evaluation methods,and the clinical application of emerging technologies.Currently,the definition of DMVO is mostly based on vascular anatomical features and clinical functional deficits,the etiology of DMVO can be classified as primary and secondary.Due to the small diameter and tortuous running course of distal medium vessels,individualized treatment strategies are often required for patients with DMVO.This review focuses on the efficacy and safety of the therapeutic techniques,including direct thrombectomy,aspiration thrombectomy,stent retriever thrombectomy,and bridging therapy,in treating DMVO,besides,this review also discusses the role of imaging methods,including non-enhanced CT(NCCT),CT perfusion(CTP),CT angiography(CTA),and MRI in the patient screening and treatment decision-making.Meanwhile,the emergence of novel small-scale thrombectomy devices and techniques offers new possibilities for improving recanalization rates and reducing complication risks.Overall,although preliminary studies suggest that MT has promising clinical benefits for the treatment of DMVO,the available evidence remains limited.High-quality randomized controlled trials are urgently needed to further formulate the optimal treatment strategies and promote the precision interventional therapy.

Fetal growth restriction(FGR)refers to the failure of a fetus to reach the level of growth potential determined by its genetic potential.It is a common obstetric complication,occurring in 5%to 10%of pregnancies.As a major risk factor for perinatal death and adverse neonatal outcomes,early prediction of FGR is crucial for optimizing pregnancy management.Existing evidence suggests that FGR is significantly associated with a variety of adverse pregnancy outcomes,including intrauterine hypoxia,preterm birth,neonatal asphyxia,and even neonatal mortality.It may also affect long-term neurological development and increase the risk of metabolic diseases in adulthood.Its pathogenesis is complex,which may involve placental blood flow perfusion insufficiency and genetic factors.Ultrasound parameters are the main basis for the diagnosis of FGR,among which fetal biological and hemodynamic parameters are of great value.Elevated umbilical artery blood flow resistance index,absent or reversed end-diastolic blood flow,and placental insufficiency are associated with the severity of FGR.However,approximately 10%of fetuses diagnosed by ultrasound as having FGR are later confirmed to be healthy small-for-gestational-age(SGA)infants after birth,and this false positive result may lead to unnecessary clinical interventions.Currently,there is no recognized accurate prediction model for FGR in clinical practice.Future research should focus on establishing unified diagnostic criteria and developing multi-index joint prediction tools based on artificial intelligence(AI).Early prediction and intervention for FGR are of great significance to improve perinatal outcomes.This paper reviewed the predictive value of ultrasound parameters,blood indicators,and their integration with AI for FGR,in order to provide a basis for clinical decision-making.

Objective To investigate the clinical manifestations,risk factors,treatment strategies and clinical prevention feasibility of diabetic ketoacidosis(DKA)after coronary artery bypass transplantation(CABG).Methods Clinical data of 9 patients with ketoacidosis after CABG surgery treated and treated by CICU in the Intensive Care Unit of Cardiac Surgery in Nanjing Gulou Hospital from January 2022 to January 2024 were retrospectively analyzed,and the diagnosis and treatment process and short-term postoperative follow-up were conducted to evaluate the causes of ketoacidosis in order to obtain clinical characteristics.To provide early warning information for follow-up diagnosis and treatment,and to evaluate the effect of perioperative corrective treatment strategy on the short-term prognosis of patients.Results The median duration of DKA in the 9 patients was 2.6 days after surgery,and the clinically suggestive symptoms were tachyarrhythmia(8/9),hypotension(4/9),polyuria(6/9),intractable hyperglycemia(3/9),and derangation(5/9).Analysis of concomitant manifestations or risk factors were mainly the perioperative use of sodium-glucose cotransporter 2 inhibitors(SGLT2i)(9/9),age＞60 years old.The main diagnosis was based on abnormal blood ketone and urine ketone.Blood gas analysis suggested metabolic acidosis,and BE showed serious negative performance.After early diagnosis,8 patients took the volumetric surplus strategy,and the average correction time was 5.6 days.One patient was slow to correct and eventually died from other types of severe complications.Conclusion Perioperative use of SGLT2-i drugs in CHD patients with heart failure and type 2 diabetes is a high risk factor for DKA.The strategy of early diagnosis and parallel capacity surplus is an important way to correct DKA.

Cancer is one of the major diseases of high morbidity and mortality worldwide,and its therapeutic approaches are facing great challenges.Immunotherapy,especially the activation of innate immunity represented by the cGAS-STING signaling pathway,is the current research hotspot in tumor immunotherapy.Activation of innate immune response by gas therapy is the latest development in tumor therapeutic approaches,especially the use of gas signaling molecules(NOx CO,H2S and SO2)to activate the cGAS-STING signaling pathway to induce intrinsic immunity of the organism,which leads to anti-tumor immunotherapy.Although intrinsic immunity activated by gas signaling molecules plays an important role in tumor immunotherapy,few reviews have been reported on its association with the cGAS-STING signaling mechanism.In this paper,we will comprehensively describe how gas signaling molecules damage the mitochondrial matrix and DNA damage through oxidative/nitrosative stress,thereby activating the cGAS-STING signaling pathway and triggering the innate immune cascade,aiming to summarize the process of activation of anti-tumor immune effects by gas signaling molecules,and to provide more references for the gas therapies in the future anti-tumor immunity research.

Objective:To analyze the expression level of protein arginine methyltransferase 5 (PRMT5) in pancreatic cancer tissues and its correlation with prognosis using bioinformatics methods, and to explore its potential mechanisms.Methods:Expression analysis of the PRMTs family members was performed based on the gene expression profiles of 178 pancreatic cancer tissues from the Gene Expression Profiling Interactive Analysis (GEPIA) database and 171 normal pancreatic tissues from the TCGA and GTEx databases. Using the median expression level of PRMTs family members in pancreatic cancer tissues as the cutoff, patients were divided into high-expression and low-expression groups, and Kaplan-Meier curves for overall survival (OS) and disease-free survival (DFS) were plotted. The correlation between PRMT5 expression and the expression of oncogenes such as KRAS, TP53, BRCA1, BRCA2, and SLC39A4 was analyzed. Functional enrichment analysis was conducted on genes similar to PRMT5, and a protein-protein interaction (PPI) network was constructed to analyze the interaction relationships among these similar genes. Pancreatic cancer PANC1 and AsPC-1 cells cultured in standard medium served as the control group, while PANC1 and AsPC-1 cells cultured in medium supplemented with the PRMT5 inhibitor EPZ015666 served as the intervention group. Cell viability was assessed using the CCK-8 assay, and cell cycle progression was analyzed by flow cytometry.Results:The expression level of PRMT5 in pancreatic cancer tissues was significantly higher than that in normal pancreatic tissues and showed a significant negative correlation with both OS and DFS. Patients with high PRMT5 expression had a shorter median survival time compared to those with low expression (17.2 months vs 19.5 months). PRMT5 expression was significantly positively correlated with the expression of oncogenes KRAS, TP53, BRCA1, BRCA2, SLC39A4, and KLF5. Genes similar to PRMT5 were primarily enriched in cell cycle-related signaling pathways, and NOP58 identified as a hub gene in the PPI network. Compared to the control group, the proliferation activity of PANC1 and AsPC-1 cells in the intervention group was significantly reduced [(67.3±1.9)% vs (100±4.4)% for PANC1; (60.5±2.7)% vs (100.0±1.7)% for AsPC-1], and the proportion of cells in the G1 phase was significantly increased [(51.6±0.7)% vs (35.3±2.7)% for PANC1; (51.2±0.9)% vs (29.7±2.2)% for AsPC-1]. All these differences were statistically significant (all P values <0.05). Conclusions:High expression of PRMT5 was closely associated with poor prognosis in pancreatic cancer patients, and it may contribute to pancreatic cancer progression by regulating the cell cycle.

BACKGROUND: Delayed platelet engraftment is a common complication after umbilical cord blood transplantation (UCBT), and there is no standard therapy. Avatrombopag (AVA) is a second-generation thrombopoietin (TPO) receptor agonist (TPO-RA) that has shown efficacy in immune thrombocytopenia (ITP). However, few reports have focused on its efficacy in patients diagnosed with thrombocytopenia after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: We conducted a retrospective study at the First Affiliated Hospital of the University of Science and Technology of China to evaluate the efficacy of AVA as a first-line TPO-RA in 65 patients after UCBT; these patients were compared with 118 historical controls. Response rates, platelet counts, megakaryocyte counts in bone marrow, bleeding events, adverse events and survival rates were evaluated in this study. Platelet reconstitution differences were compared between different medication groups. Multivariable analysis was used to explore the independent beneficial factors for platelet implantation. RESULTS: Fifty-two patients were given AVA within 30 days post-UCBT, and the treatment was continued for more than 7 days to promote platelet engraftment (AVA group); the other 13 patients were given AVA for secondary failure of platelet recovery (SFPR group). The median time to platelet engraftment was shorter in the AVA group than in the historical control group (32.5 days vs . 38.0 days, Z  = 2.095, P  = 0.036). Among the 52 patients in the AVA group, 46 achieved an overall response (OR) (88.5%), and the cumulative incidence of OR was 91.9%. Patients treated with AVA only had a greater 60-day cumulative incidence of platelet engraftment than patients treated with recombinant human thrombopoietin (rhTPO) only or rhTPO combined with AVA (95.2% vs . 84.5% vs . 80.6%, P  <0.001). Patients suffering from SFPR had a slightly better cumulative incidence of OR (100%, P  = 0.104). Patients who initiated AVA treatment within 14 days post-UCBT had a better 60-day cumulative incidence of platelet engraftment than did those who received AVA after 14 days post-UCBT (96.6% vs . 73.9%, P  = 0.003). CONCLUSION Compared with those in the historical control group, our results indicate that AVA could effectively promote platelet engraftment and recovery after UCBT, especially when used in the early period (≤14 days post-UCBT).
