Osteoporosis is a metabolic dysregulation of bone that occurs mainly in postmenopausal women,and the hyperfunction of osteoclasts is the primary contributor to postmenopausal ***,the development of effective therapeutic drugs and precise delivery systems remains a challenge in the field of anti-absorption ***,we reported theα-cyperone(α-CYP)for anti-osteoporosis and developed a liposome-based nano-drug delivery system ofα-CYP,that specifically targets the bone resorption ***,we found that theα-CYP,one of the major sesquiterpenes of Cyperus rotundus L.,attenuated the progression of osteoporosis in ovariectomized(OVX)mice and down-regulated the expression of phosphorylated proteins of phosphoinositide 3-kinase(PI3K)and protein kinase B(Akt),causing down-regulation of osteoclast-related genes/proteins and curbing osteoclast ***,α-CYP reversed the activation of osteoclastic differentiation and enhanced osteoporosis-related proteins expression caused by PI3K/Akt agonist(YS-49).More importantly,we adopted the osteoclastic resorption surface targeting peptide Asp8 and constructed the liposome(lipαC@Asp8)to deliverα-CYP to osteoclasts and confirmed its anti-osteoporosis effect and enhanced osteoclast inhibition by blocking PI3K/Akt *** conclusion,this study demonstrated thatα-CYP inhibits osteoclast differentiation and osteoporosis development by silencing PI3K/Akt pathway,and the liposome targeting delivery systems loaded withα-CYP might provide a novel and effective strategy to treat osteoporosis.

以钒电池为代表的液流电池有望成为大规模储能应用的电池技术,得益于其循环寿命长、能效高、可独立调节功率和能量等诸多优点。钒作为钒电池电解液的核心元素,由于相对稀缺导致成本过高,制约着钒电池产业的发展。因此,拓展钒资源途径成为当前研究的重点。而绝大部分钒产量来自于钒钛磁铁矿冶炼得到的钒渣,实现钢渣高效提钒成为我国钒产业可持续发展的关键举措。本文使用含钒钢渣为原料,在温度为1000℃,时间为3 h,配钙比为8%的条件下进行焙烧,最后以焙烧渣作为浸出原料,通过单因素试验研究了浸出温度、液固比、浸出时间及硫酸浓度对钒元素浸出的影响。采用高锰酸钾-硫酸亚铁铵滴定法,计算不同因素下钒的浸出率,最终得出浸出效果的最优参数。结果表明,在浸出温度为90℃、液固比为10∶1 mL/g、浸出时间为60 min、硫酸浓度达到35%时,钒的浸出效果最好,浸出率高达80.25%。这为缓解钒资源缺口提供了新的思路,有助于降低钒电池产业生产成本,进而加快国家的电化学储能建设。
