Summary: To address volume expansion from active sulfur and shuttle effect from polysulfides during the electrochemical process of lithium sulfur batteries, nitrogen/sulfur co‐doping porous active carbons (NS‐PACs) derived from biomass cattail were manufactured by one‐step activated hydrothermal method. The effects of N/S atoms co‐doping and the activation of KOH on NS‐PACs were investigated in the macro‐morphology, micro‐structure, and electrochemical performance using scanning electron microscopy (SEM), X‐ray photoelectron spectroscopy (XPS), Brunauer‐Emmett‐Teller (BET), as well as galvanostatic charge/discharge tests. The experimental data demonstrated that the NS‐PACs show stable foam‐likes porous structure, and the specific surface area (SSA) and pore volumes are 2155.81 m2g−1 and 1.43 cm3g−1, respectively, and reveals perfect N/S atoms doping with S atomic content of 1.4% and N atomic content of 0.78%. Moreover, the initial discharge capacity of NS‐PACs is 1477.8 mAh g−1 at 0.1 C and the extraordinary long‐run cycling stability after 500 cycles reaches 803.4 mAh g−1 at 2.0 C. These outstanding electrochemical performances of NS‐PACs are associated with efficient physical confinement by porous architecture together with the potent chemical adsorption of N/S atoms with polysulfide.

A hexagonal prism CuSn alloy was prepared at room temperature from 1-ethyl-3-methylimidazolium dicyanamide ([Emim][DCA]) by the direct template-free electrodeposition method with different concentrations of Cu(I) and Sn(II) at a low current density of 0.04 A dm−2. Moreover, the electrodeposition time was also investigated, and the results indicated that the composition of the CuSn alloy became complex and the structure turned unstable with expanding time. The cycling performance of the hexagonal prism-structural CuSn electrode was investigated, with the first discharge capacity of 345 mAh g−1 and a discharge capacity of about 210 mAh g−1 after 10 cycles.

Background and Aims. There are few studies on the prevalence and clinical characteristics of portopulmonary hypertension (POPH) in patients with portal hypertension. In addition, invasive right heart catheterization further limits the clinical diagnosis of POPH patients. Methods. From January 2018 to December 2019, 1004 patients with portal hypertension were treated in the Department of Hepatology, the First Hospital of Jilin University. Based on the inclusion and exclusion criteria, 188 patients with portal hypertension were finally included. We collected complete clinical data, laboratory examinations, and imaging examinations. Patients were divided into a POPH group and a non-POPH group based on echocardiographic results. We calculated the prevalence of POPH in patients with portal hypertension. The differences in clinical characteristics of the two groups of patients were compared. Results. The prevalence of POPH in patients with portal hypertension was 2.8%. Among the 188 patients with portal hypertension with fingertip oxygen saturation < 95 % at rest, 28 patients had POPH (12 males and 16 females), with an average age of 63 ± 8 , and 160 patients did not have POPH (110 males, 50 women), with an average age of 59 ± 11. The proportion of women in the POPH group (P < 0.01) and patients without liver cancer (P = 0.044) was high. Compared to patients without POPH, patients with POPH had lower hemoglobin (related to the severity of anemia, P < 0.01), higher creatinine (P < 0.05), and lower partial pressure of oxygen and carbon dioxide (P < 0.05). Patients with POPH had a higher incidence of atrial enlargement, ventricular enlargement, mitral valve regurgitation, tricuspid regurgitation, pulmonary artery widening, pericardial effusion, and aortic regurgitation than those without POPH. The risk of POPH did not increase with the aggravation of the Child-Pugh classification. Conclusion. The prevalence of POPH in patients with portal hypertension is 2.8%. The proportion of women and nonliver cancer in POPH patients was higher than that in non-POPH patients. In addition, the POPH group had higher creatinine and lower hemoglobin, and echocardiography showed that POPH patients had more cardiac structural changes. In patients with portal hypertension, the risk in patients with POPH has nothing to do with the Child-Pugh classification and MELD score. [ABSTRACT FROM AUTHOR]

Background and Aims. Alcohol-associated liver disease is exhibiting an increasing disease burden. In terms of pathogenesis, inflammation is closely related to alcohol-induced liver injury. The neutrophil-to-lymphocyte ratio (NLR) is a novel inflammatory biomarker. Here, we aim to evaluate the role of the NLR and other biomarkers in predicting short-term mortality in alcoholic cirrhotic patients. Methods. This was a retrospective study that included 459 male alcoholic cirrhosis patients. Among them, 345 patients completed follow-up. Based on their 30-day mortality information, patients were separated into surviving and nonsurviving groups. Demographic, clinical, and biochemical features were collected for further analysis. Logistic regression was used to identify factors associated with short-term mortality, and receiver operating characteristic (ROC) curve analysis was used to establish the predictive value of these factors. Results. The prognostic scores were significantly higher in the nonsurviving group than in the surviving group: NLR: 5.5 vs. 3.2 (P < 0.001), model for end-stage liver disease (MELD): 15.4 vs. 7.9 (P < 0.001), Maddrey's discriminant function (MDF): 39.8 vs. 12.7 (P < 0.001), and the integrated MELD (i-MELD): 37.9 vs. 28.4 (P < 0.001). Logistic regression demonstrated that albumin (ALB), NLR, and i-MELD values were significantly correlated with patient death in 30 days. On ROC analysis, the diagnostic accuracy for 30-day mortality of the NLR (area under the ROC curve (AUROC) of 0.72, P < 0.001) was similar to that of the MELD or i-MELD (AUROCs of 0.71 and 0.74, respectively, P < 0.001). The new biomarker, NLA, calculated as 100 × NLR / ALB , had the best prognostic value. The cutoff values of the NLR and NLA for predicting 30-day mortality were 4.2 and 19.6, respectively. Conclusions. The NLR and its related biomarker NLA are simple and robust predictors of 30-day mortality in alcoholic cirrhosis patients. [ABSTRACT FROM AUTHOR]
