Objective:To compare the aortic remodeling of the Fabulous stent system and standard thoracic aortic endovascular repair (TEVAR) on distal aorta type B aortic dissection (TBAD). Methods:The prospective data collected between Dec 2017 and Oct 2019 from 134 patients with type B aortic dissection (TBAD) who underwent treatment with the "Fabulous" stent system, and retrospective data from 159 TBAD patients receiving standard TEVAR from corresponding multicenter. By using propensity score matching analysis, we compared the prognosis and aortic remodeling outcomes in patients undergoing Fabulous and standard TEVAR treatments during a 1-year postoperative follow-up.Results:In this study, 62 patients in Fabulous group and 62 patients in standard TEVAR were included.There were no significant statistical differences in baseline characteristics between the two groups. In terms of aortic remodeling in bare stent region, Fabulous group had better change trends of diameter of true lumen [10.6 (4.4, 14.5) mm vs. 4.7 (0.9, 10.7) mm, P=0.001] and false lumen [-24.2 (-30.5, -4.9) mm vs. 0.7 (-11.8, 2.3) mm, P<0.001] than those in the standard TEVAR group. The rate of complete false lumen thrombosis was also higher in the Fabulous group (62.9% vs. 37.1%, P=0.042). Conclusion:The Fabulous stent system, when compared to standard TEVAR surgery, demonstrates good aortic remodeling outcomes in the distal aorta.

Objective:To compare the efficacy and safety of azacitidine combined with venetoclax or CAG regimen in the treatment of newly treated elderly patients with acute myeloid leukemia (AML).Methods:A retrospective cohort study was conducted. The clinical data of 34 newly treated elderly patients with AML treated in the Fifth People's Hospital of Datong from May 2018 to August 2023 were retrospectively analyzed. According to the treatment regimen, all patients were divided into venetoclax group (azacitidine + venetoclax, 17 cases) and CAG group (azacitidine + CAG regimen, 17 cases). The clinicopathological characteristics, efficacy, adverse reactions and survival of the both groups were compared.Results:There were no statistically significant differences in the clinical data of both groups (all P > 0.05). The complete remission (CR) rate and the objective response rate (ORR) in venetoclax group were higher than those in CAG group [CR: 70.6%(12/17) vs. 47.1% (8/17); ORR: 82.4% (14/17) vs. 64.7% (11/17)],while the differences in CR and ORR were not statistically significant (χ 2 = 2.00, P = 0.163; χ 2 = 2.00, P = 0.244). The follow-up time[ M ( Q1, Q3)] was 25.4 months (7.2 months, 60.3 months). At the end of follow-up, 19 of 34 patients survived (13 cases in venetoclax group and 6 cases in CAG group); 15 died (4 cases in venetoclax group and 11 cases in CAG group). The median overall survival (OS) time was 14.22 months (95% CI: 8.2-60.3 months) and 10.56 months (95% CI: 7.2-50.2 months), respectively in venetoclax group and CAG group;the median progression-free survival (PFS) time was 9.97 months (95% CI: 5.4-40.5 months) and 6.82 months (95% CI: 5.0-36.2 months), respectively, and there were no statistically significant differences in OS and PFS between the two groups (all P > 0.05). Grade 3-4 hematological adverse reactions occurred in 16 and 14 patients in venetoclax group and CAG group, respectively. There were no significant differences in granulocyte deficiency time, platelet deficiency time, infection and bleeding incidence between the two groups (all P > 0.05). Conclusions:Azacitidine combined with venetoclax or CAG regimen have better clinical efficacy and safety for newly treated elderly patients with AML.

Objective To evaluate the short-term outcomes of thoracic endovascular aortic repair (TEVAR) with outer branched and inner branched endografts in the treatment of Stanford type B aortic dissection (TBAD), and to analyze the effects of endografts on blood flow status of aortic dissection by computational fluid dynamics (CFD). Methods The clinical data of TBAD patients treated with outer branched endograft technology in outer branched endograft group and inner branched endograft technology in inner branched endograft group in Department of Vascular Surgery Tianjin Medical University General Hospital from May 2018 to December 2021 were collected, and the short-term results of two groups were analyzed retrospectively. Based on CT angiography images of patients in two groups, one typical case in each group was selected to construct personalized 3D model and CFD numerical simulation was performed. The parameters including flow field velocity distribution, wall pressure and wall shear stress (WSS) before and after surgery were compared and analyzed. Results A total of 55 cases with TBAD were enrolled, consisting of 49 cased in outer branched endograft group and 6 cases in inner branched endograft group. There was no statistical difference in baseline data between two groups, and surgical success rate were both 100%. Reconstruction of left subclavical artery(LSA) simple was 41(83.7%) cases in outer branched endograft group and all 6 cases in inner branched endograft group. In outer branched endograft group there were 5 cases with reconstruction of left common carotid artery (LCCA) combined with bridging carotic clavical artery, 2 cases with reconstruction of LCCA combined with LSA embolism, and 1 case with reconstruction of LCCA combined with LSA window. Four cases were lost during follow-up in outer branched endograft group. There were no significant differences in the aorta-related mortality rate (P=1.000), branch patency rate (P=1.000) and avoidance of secondary intervention of target vessels between the two groups during the perioperative period and follow-up period (P=0.298). After endograft implantation of two groups the flow field disturbance in dissection lesions improved significantly, aortic blood flow pattern restored normal, and local abnormally increased WSS decreased. However, the interference of inner branch on aortic arch and blood flow of branch was more obvious than that of outer branch. Conclusions Both outer branched endograft and inner branched endograft TEVAR for reconstruction of LSA had good short-term results in the treatment of TBAD. Compared with inner branched endograft, outer branched endograft has a higher anatomical fit and can restore the normal blood flow to a greater extent for aortic arch.

Objective:To establish a model C-GALAD for detecting hepatocellular carcinoma (HCC) from the chronic liver disease and healthy people based on the serum markers.Methods:A clinical cohort including 229 hepatocellular carcinoma patients, 2 317 patients with chronic liver disease and 982 healthy people, was retrospectively collected from eight hospitals or physical examination institutions from April 2018 to October 2020. The data were divided into a training set and a testing set by stratified sampling with a 6∶4 ratio. A predictive model was established on the training set using a logistic backward regression method and validated on the testing set. In addition, clinical data from March to July 2021 in Beijing You′ an Hospital affiliated to Capital Medical University, including 84 patients with liver cancer and 204 patients with chronic liver disease collected were used for external independent validation of the model. The receiver operating characteristic curve (ROC) area under curve (AUC), the sensitivity and the specificity were used to evaluate the effectiveness of the model.Results:Through the logistic backward regression method, the seven signatures including age, gender, alpha-fetoprotein (AFP), alpha-fetoprotein alloplasm-3 ratio (AFP-L3%), des-gamma-carboxyprothrombin(DCP), platelet (PLT) and total bilirubin (TBIL) were selected as risk factors in the detection model. The area under the ROC curve (AUC) of the model on the testing set was 0.954, with an 88.04% sensitivity and a 94.85% specificity, and the AUC of model on the external independent validation set was 0.943, with an 89.29% sensitivity and a 90.2% specificity, which were better than other published models.Conclusion:The C-GALAD Ⅱ model can accurately predict the risk of hepatocellular carcinoma occurrence, and thus provide a trustworthy diagnosis method of hepatocellular carcinoma.

Objective:To investigate the effects of histone deacetylase 3 (HDAC3) on the pyroptosis of breast cancer (BC) cells via regulating miR-625/anti-silencing function 1B (ASF1B) and its mechanism.Methods:The expression level of HDAC3, miR-625 and ASF1B in BC tissue, adjacent normal tissue, BC cell lines (T47D, MCF7 and MDA-MB-231) and human normal breast epithelial cell MCF-10A was detected by qRT-PCR. The expression level of cell pyroptosis related protein NLRP3, Caspase-1 and GSDMD was detected by Western blot. The expression level of IL-18 and IL-1βwere detected by ELISA. ChIP experiment was used to determine the interaction between HDAC3 and miR-625. The dual luciferase reporter assay was used to verifiy the targeted regulation between miR-625 and ASF1B.Results:Compared with adjacent normal tissue and MCF-10A cells, the expression of HDAC3 and ASF1B was increased and the expression of miR-625 was decreased in BC tissue and cells (all P<0.05) . Compared with si-NC group, the protein expression level of NLRP3, Caspase-1 and GSDMD in si-HDAC3 group was increased, and the concentration of IL-18 and IL-1β in cell culture supernatant was increased (all P<0.05) . HDAC3 inhibited the expression of miR-625 by binding to the promoter region of miR-625 ( P<0.05) . Compared with si-HDAC3+miR-NC group, The expression of NLRP3, Caspase-1, GSDMD, IL-18 and IL-1β in si-HDAC3+miR-625 inhibitor group was decreased (all P<0.05) . ASF1B was confirmed as a target gene of miR-625, the level of pyroptosis related factors in si-HDAC3+pcDNA3.1-ASF1B group was significantly lower than that in si-HDAC3 + pcDNA3.1-NC group. Conclusion:HDAC3 up regulates the expression of ASF1B by inhibiting miR-625, and then inhibits BC cell pyroptosis.

Ornithine decarboxylase (ODC) is a key enzyme in the biosynthetic pathway of polyamines and catalyzes the decarboxylation of ornithine to produce putrescine. Inhibition of ODC activity is a potential approach for the prevention and treatment of many diseases including cancer, as the expression levels and the activities of ODC in many abnormal cells and tumor cells are generally higher than those of normal cells. The discovery and evaluation of ODC inhibitors rely on the monitoring of the reaction processes catalyzed by ODC. There are several commonly used methods for analyzing the activity of ODC, such as measuring the yield of putrescine by high performance liquid chromatography, or quantifying the yield of isotope labelled carbon dioxide. However, the cumbersome operation and cost of these assays, as well as the difficulty to achieve high-throughput and real-time detection, hampered their applications. In this work, we optimized a real-time label-free method for analyzing the activity of ODC based on the macromolecule cucurbit[6]uril (CB6) and a fluorescent dye, DSMI (trans-4-[4-(dimethylamino) styryl]-1-methylpyridinium iodide). Finally, the optimized method was used to determine the activities of different ODC inhibitors with different inhibition mechanisms.

Although the tumor suppressor P53 is known to regulate a broad network of signaling pathways, it is still unclear how certain drugs influence these P53 signaling networks. Here, we used a comprehensive single-cell multiomics view of the effects of ginsenosides on cancer cells. Transcriptome and proteome profiling revealed that the antitumor activity of ginsenosides is closely associated with P53 protein. A miRNA-proteome interaction network revealed that P53 controlled the transcription of at least 38 proteins, and proteome-metabolome profiling analysis revealed that P53 regulated proteins involved in nucleotide metabolism, amino acid metabolism and "Warburg effect". The results of integrative multiomics analysis revealed P53 protein as a potential key target that influences the anti-tumor activity of ginsenosides. Furthermore, by applying affinity mass spectrometry (MS) screening and surface plasmon resonance fragment library screening, we confirmed that 20()-protopanaxatriol directly targeted adjacent regions of the P53 DNA-binding pocket and promoted the stability of P53-DNA interactions, which further induced a series of omics changes.
