Chinese Chemical Letters 2025年第2期36卷 161-172页

作者： Haobo Wang fei Wang Yong Liu Zhongxiu Liu Yingjie Miao Wanhong Zhang Guangxin Wang Jiangtao Ji Qiaobao Zhang School of Materials Science and Engineering Provincial and Ministerial Co-construction of Collaborative Innovation Center for Non-ferrous Metal new Materials and Advanced Processing Technology Henan University of Science and Technology Faculty of Engineering Huanghe Science and Technology University Henan Key Laboratory of Non-Ferrous Materials Science & Processing Technology Henan University of Science and Technology College of Agricultural Equipment Engineering Henan University of Science and Technology State Key Laboratory of Physical Chemistry of Solid Surfaces College of Materials Xiamen University

Lithium metal is one of the most promising anodes for lithium batteries because of their high theoretical specific capacity and the low electrochemical potential. However, the commercialization of lithium metal anodes(LMAs) is facing significant obstacles, such as uncontrolled lithium dendrite growth and unstable solid electrolyte interface, leading to inferior Coulombic efficiency, unsatisfactory cycling stability and even serious safety issues. Introducing low-cost natural clay-based materials(NCBMs) in LMAs is deemed as one of the most effective methods to solve aforementioned issues. These NCBMs have received considerable attention for stabilizing LMAs due to their unique structure, large specific surface areas, abundant surface groups, high mechanical strength, excellent thermal stability, and environmental friendliness. Considering the rapidly growing research enthusiasm for this topic in the last several years, here, we review the recent progress on the application of NCBMs in stable and dendrite-free *** different structures and modification methods of natural clays are first summarized. In addition, the relationship between their modification methods and nano/microstructures, as well as their impact on the electrochemical properties of LMAs are systematically discussed. Finally, the current challenges and opportunities for application of NCBMs in stable LMAs are also proposed to facilitate their further development.

Electroacupuncture enhances the mitophagy of granulosa cells in premature ovarian insufficiency model mice by inactivating the hippo-yes-associated protein/transcriptional co-activator with postsynaptic density protein,drosophila disc large tumor suppresso

引用

Journal of Traditional Chinese Medicine 2025年第1期45卷 13-21页

作者： WU Jiaman TANG Meng LUO Yu ZHU Haimin ZHAO Tianqi MA fei NING Yan Department of Chinese Medicine Affiliated Shenzhen Maternity and Child Healthcare HospitalSouthern Medical University Guangzhou University of Chinese Medicine Southern Medical University

OBJECTIVE: To investigate the potential mechanism of electroacupuncture（EA） in alleviating premature ovarian insufficiency（POI） and to provide a theoretical basis for EA treatment of POI. METHODS: For this purpose, a POI mice model was developed by injecting 12 mg/kg busulfan and 120 mg/kg cyclophosphamide intraperitoneally to induce POI. It was then proceeded by EA intervention at Guanyuan（CV4） acupoint on the second day following modeling. Similarly, apoptosis in ovarian granulosa cells was detected by terminal deoxynucleotidyl transferase d UTP nick end labeling staining, while enzyme-linked immunosorbent assay was employed for measuring serum folliclestimulating hormone（FSH）, luteinizing hormone（LH）, estrogen（E2）, and anti-müllerian hormone（AMH） levels. Moreover, transmission electron microscopy（TEM） was employed for examining mitochondrial morphology, while autophagy and hippo-yes-associated protein/transcriptional co-activator with postsynaptic density protein, drosophila disc large tumor suppressor, and zonula occludens-1 protein binding motif（YAP/TAZ） pathway related protein levels in ovarian tissue were detected via Western blotting. RESULTS: Analysis of serum levels of various hormones indicated that serum FSH and LH were reduced in EA compared to the POI group, while E2and AMH levels were found to be elevated in EA compared to the POI group. The EA was found to inhibit apoptosis in granulosa cells in POI model mice, in addition to improved mitochondrial damage and significantly improved mitophagy. Pathway analysis revealed that EA was involved in activating the hippo-YAP/TAZ pathway, followed by reversing EA effects on granulosa cell apoptosis and mitophagy with the use of verteporfin, an autophagy and YAP-T-cell factor/enhancer of split and activator of transcription domain family member interaction inhibitor. CONCLUSIONS: EA at the Guanyuan（CV4） acupoint protected the granulosa cell by inhibiting cell apoptosis and promoting mitophagy, which was mediate
