Objective: To construct a new thrombus risk assessment model and evaluate its predictive ability for venous thromboembolism (VTE) in the patients with malignant tumors, and to provide the basis for the early predition of the malignant tumor patients with high risk for VTE. Methods: A total of 128 untreated malignant tumor patients were included, of which 40 were diagnosed with VTE within 2 months of malignant tumor diagnosis and categorized as VTE group. A total of 88 patients who did not develop VTE were categorized as non-VTE group. The clinical risk factors and laboratory indicators of the patients in two groups were compared and analyzed; the types of thrombotic events of the patients were analyzed; the diagnostic values of thrombin-antithrombin-complex (TAT), α2-plasmin inhibitor-plasmin complex (PIC), D-dimer(D-dimer), and fibrin degradation products(FDP) in malignant tumors complicated by VTE were assessed using receiver operating characteristic (ROC) curve analysis; Multivariate Logistic regression analysis was used to analyze the correlations of the clinical risk factors and biomarkers with the malignant tumors complicated with VTE. A new thrombus risk assessment model was constructed, consisting of TAT≥0. 70 μg·L-1, poor differentiation, and cardiovascular risk factors. The predictive probability of the model for malignant tumors complicated by VTE was evaluated based on the significance, goodness of fit, calibration curve, and C value of the model. The clinical application value of the new thrombus risk assessment model, COMPASS-CAT risk score (CRS), and Khorana risk score (KRS) in assessing malignant tumor patients complicated by VTE was compared using the C value and decision curve analysis (DCA). Results: The plasma levels of TAT (P<0. 001), PIC (P<0. 001), D-dimer (P<0. 05), and FDP (P<0. 01) of the patients in VTE group were higher than those in nonVTE group. Compared with the patients without cardiovascular risk factors, poor differentiation, and lymphatic metastasis, the malignant tumor patients with cardiovascular risk factors (P<0. 001), poor differentiation (P<0. 001), and lymphatic metastasis (P<0. 05) were more likely to develop VTE. Most VTE events (65%) were isolated deep vein thromboembolism(DVT). The ROC curve analysis showed that the area under the curve (AUC), sensitivity, and specificity of TAT and PIC were higher than those of D-dimer and FDP. TAT≥0. 70 μg·L-1 (P<0. 05), poor differentiation (P<0. 01), and cardiovascular risk factors(P<0. 01) were the independent risk factors for VTE in the malignant tumor patients. A new thrombus risk assessment model consisting of TAT≥0. 70 μg·L-1, poor differentiation, and cardiovascular risk factors was constructed. The new risk assessment model had a high goodness of fit (P=0. 805) and good predictive ability during internal validation (χ² =75. 266, P<0. 001). The ROC curve analysis results showed that the C values for the new thrombus risk prediction model, CRS, and KRS were 0. 908, 0. 676, and 0. 541, respectively. The DCA curve analysis results showed that the new thrombus risk assessment model had a higher net benefit rate compared with CRS and KRS. Conclusion: TAT and PIC have greater diagnostic efficiency than D-dimer in the early prediction of the malignant tumor patients with high-risk VTE. For the patients included in this study, the new thrombus risk assessment model, constructed from TAT≥0. 70 μg·L-1, poor differentiation, and cardiovascular risk factors, has superior diagnostic efficiency and clinical predictive value compared with CRS and KRS.

By adding different biomass（corn cob or pine sawdust） to hypercoal, the activated carbon electrode materials for double electric layer capacitors were prepared. The effect of biomass on the structure and electrochemical performance of hypercoal-based activated carbon was explored. Its structure and composition were characterized by SEM, XRD, FTIR and N2 desorption. Its electrochemical performance was tested by cyclic voltammetry, constant current charge-discharge and AC impedance. In terms of biomass composition, the addition of biomass with high cellulose content is beneficial to the development of mesopore and the pore structure is more perfect. High cellulose and hemicellulose content can effectively reduce the impedance of carbon materials, and make the ion transport between pore structures more rapid. When corn cob was added to hypercoal, the specific capacitance increased by 45% and the charge transfer resistance decreased by 65%. Adding pine sawdust to hypercoal can increase the specific capacitance by 30% and decrease the charge transfer resistance by 35%. It is proved that adding biomass with high cellulose content is more beneficial to improve the structure and electrochemical performance of activated carbon. [ABSTRACT FROM AUTHOR]

Objective To analyze the relationship between preoperative serum alanine aspartate aminotransferase /aminotransferase (AST/ALT) ratio and prognosis of patients with Budd-Chiari syndrome (BCS). Methods Data of 280 patients with BCS admitted to the Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. The median value of AST/ALT ratio (0.75) was used for grouping. There were 142 cases in group AST/ALT ratio ≤ 0.75 and 138 cases in group AST/ALT ratio > 0.75. All patients underwent interventional surgery and followed up for at least 5 years. According to the recurrence of follow-up results, the relationship between preoperative serum AST / ALT levels and recurrence was analyzed retrospectively. Results There were significant differences in gender, Child-Pugh grade of liver function and recurrence rate between the two groups. The mean vascular patency time were 45 (37, 52) and 40 (21, 49) months for AST/ALT ratio ≤ 0.75 group and AST/ALT ratio >0.75 group. The mean vascular patency time was significantly shorter in AST/ALT ratio > 0.75 group than that of AST/ALT ratio ≤ 0.75 group (Z=2.159，P＜0.05). The cumulative patencyrates were 94.4%, 76.8% and 64.1%, respectively in AST/ALT ratio ≤0.75 group for 1, 3 and 5 years. The cumulative patency rates were 90.6%, 68.1% and 58.7% in AST/ALT ratio > 0.75 group for 1, 3 and 5 years, respectively. The 5-year cumulative patency rate was significantly lower in patients with AST/ALT>0.75 group than that of patients with AST/ALT≤ 0.75 group (Log-rank χ2=4.372，P＜0.05). Multivariate Cox regression analysis showed that the liver function of Child-Pugh classification (C) patients were easy to relapse BCS. Conclusion AST/ALT ratio is associated with recurrence of BCS after interventional therapy. Child-Pugh classification of liver function is an independent risk factor for the prognosis of BCS.
