至清胶囊的质量标准

目的：建立至清胶囊质量标准。方法：采用TLC法鉴别方中的山楂、葛根、绞股蓝和银杏叶提取物,采用HPLC法测定制剂中葛根素的含量。结果：薄层色谱清晰,分离效果好,阴性无干扰;葛根素在55~1 100 ng范围内与峰面积呈良好的线性关系（r=0.999 5）,平均回收率为99.32%,RSD=0.91%（n=6）。结论：方法简便、准确、稳定且无干扰,可作为该制剂的质量控制方法。

长三角绿色认证一体化建设

推进绿色认证是服务生态文明建设和碳达峰碳中和工作的积极举措。在统一的绿色产品标准、认证、标识体系框架下,以共同开展创新试点研究、打造“绿色认证先行区”等举措推进长三角绿色认证一体化建设,对绿色认证制度的进一步完善、认证工作区域协同化发展具有积极意义,更有利于促进认证在助力长三角生态文明体制改革和一体化发展中发挥更大的作用。

Tissue optical clearing imaging for structural changes of neuromuscular junctions after mice ischemic stroke[Invited]

Ischemic stroke causes long-term disability and results in motor impairments.Such impairments are associated with structural changes in the neuromuscular junction(NMJ),including detailed morphology and three-dimensional(3D)distribution.However,previous studies only explored morphological changes of individual NMJs after stroke,which limits the understanding of their role in post-stroke motor impairment.Here,we examine 3D distributions and detailed morphology of NMJs in entire mouse muscles after unilateral and bilateral strokes induced by photothrombosis.The results show that 3D distributions and numbers of NMJs do not change after stroke,and severe unilateral stroke causes similar levels of NMJ fragmentation and area enlargement to bilateral stroke.This research provides structural data,deepening the understanding of neuromuscular pathophysiology after stroke.

长三角地区绿色产品认证一体化建设实践及思考

2020年8月,沪苏浙皖一市三省市场监管局在浙江省湖州市签署《长三角地区共同推进绿色产品认证合作框架协议》,确定了一市三省一体化推进长三角绿色产品认证工作的创新构想。两年来,四地市场监管部门围绕助力构建绿色低碳认证体系,以联合打造“长三角绿色认证先行区”为着力点,建立共商共建共享机制,夯实区域认证监管协作基础,共同为服务全国统一大市场建设、长三角生态绿色一体化发展贡献质量认证的智慧和方案。
