AIM: To study the efficacy and safety of Fuzhenghuayu capsule (FZHY capsule, a capsule for strengthening body resistance to remove blood stasis) against liver fibrosis due to chronic hepatitis B. METHODS: Multicenter, randomized, double blinded and parallel control experiment was conducted in patients (aged from 18 to 65 years) with liver fibrosis due to chronic hepatitis B. Hepatic histologic changes and HBV markers were examined at wk 0 and 24 during treatment. Serologic parameters (HA, LM, P-Ⅲ-P, Ⅳ-C) were determined and B ultrasound examination of the spleen and liver was performed at wk 0, 12 and 24. Liver function (liver function and serologic parameters for liver fibrosis) was observedat wk 0, 6, 12, 18 and 24. Blood and urine routine test, renal function and ECG were examined before and after treatment. RESULTS: There was no significant difference between experimental group (110 cases) and control group (106 cases) in demographic features, vital signs, course of illness, history for drug anaphylaxis and previous therapy, liver function, serologic parameters for liver fibrosis, liver histologic examination (99 cases in experimental group, 96 cases in control group), HBV markers, and renal function. According to the criteria for liver fibrosis staging, meanscore of fibrotic stage(s) in experimental group after treatment (1.80) decreased significantly compared to the previous treatment (2.33, P＜0.05), but there was no significant difference in mean score of fibrotic stage(s) (2.11 and 2.14 respectively). There was a significant difference in reverse rate between experimental group (52%) and control group (23.3%) in liver biopsy. With marked effect on decreasing the mean value of inflammatory activity and score of inflammation (P＜0.05), Fuzhenghuayu capsule had rather good effects on inhibiting inflammatory activity and was superior to that of Heluoshugan capsule. Compared to that of pretreatment, there was a significant decrease in HA, LM, P-Ⅲ-P and Ⅳ-C content

Research progress in non-aqueous low-temperature electrolytes for sodium-based batteries

Science China Chemistry 2024年

作者： Jinyu Yang mingxu Wang Jiafeng Ruan Qin Li Jibo Ding Fang Fang Fei Wang School of Materials Science and Engineering Anhui University Yiwu Research Institute of Fudan University Department of Materials Science Fudan University

With the increasing demand and striking upsurge in the price of lithium carbonate, sodium-ion batteries(SIBs) have gained significant attentions due to their abundance over lithium-ion batteries(LIBs). Some prototype SIBs have achieved great progress in terms of energy densities. Although SIBs show a relatively higher tolerance at the low temperature than LIBs due to the weaker cation–solvent interaction, the low-temperature performance of SIBs remains a critical challenge restricted by the electrolyte solidification and sluggish interphasial kinetics. In this review, we briefly cover the latest research progress in usable low-temperature electrolytes for SIBs. In the meantime, the mitigating mechanism and low-temperature performance of the electrolytes in different SIB configurations are also discussed. The merits and demerits of ether-based and carbonate-based electrolytes are compared to demonstrate their potential and limitations, thus providing application principles for ether-based and carbonate-based electrolytes at low temperatures to maximize their advantages. Furthermore, mitigation strategies for lowtemperature electrolytes are emphasized to guide the future electrolyte design. Finally, we provide some perspectives on the development of the low-temperature electrolytes for SIBs.
