一片来自南极海域的红色磷虾,近日在深圳举行的“中国海洋第一展”——2026中国海洋经济博览会上被重新定义。
博览会现场,一项关于海洋磷脂的纯度纪录被刷新——科研团队发布海洋磷脂定向富集技术专利,将海洋磷脂含量从行业长期徘徊的40%至56%,首次提升至95%。这不是简单的提纯进步,而是为海洋磷脂打开了从功能食品向药用辅料、创新药研发跨越的通道。
海洋磷脂是继植物磷脂、动物磷脂之后的第三类天然脂质资源,具有独特的组成与结构特征。中国药科大学药学院副教授何东升指出,其在新型药物递送系统中具备突出的药用开发潜力。但长期以来,纯度瓶颈制约着它的应用边界。此次95%超高纯海洋磷脂的突破,使其具备了作为原料药级核心原料的资格,为海洋创新药与脂质纳米递送系统提供了全新的材料选择。
纯度之外,更关键的突破在于“抵达”。
阿尔茨海默病的药物研发被称为制药界的天堑——致病机制复杂,单靶点药物临床试验屡屡折戟;更棘手的是血脑屏障,这道保护墙让98%的小分子药物难以通过,大分子药物递送更是难上加难。该科研团队以95%高纯海洋磷脂为核心原料,构建海洋磷脂靶向递送路径,试图以“高效穿透血脑屏障、多靶点协同干预”双技术路径,突破传统药物入脑难、靶点窄、风险高、费用贵的困局。
这一设想已有初步验证支撑。科研团队与青岛大学签署阿尔茨海默病专项研究合作协议,在前期“磷虾油及高纯南极磷虾多烯磷脂酰胆碱治疗阿尔茨海默病的初步药理学评价”项目基础上,进一步深化研究。
青岛大学药学院副教授宋振华介绍,磷虾油来源高纯多烯磷脂酰胆碱在阿尔茨海默病小鼠模型中可改善认知功能、发挥神经元保护效应,同时降低神经炎症水平、改善脂质代谢紊乱;在体外血脑屏障模型中,该成分表现出更高的跨血脑屏障转运效率。这意味着,深海磷脂正在被验证为一种有潜力的脑部药物递送载体。
技术突破的背后,是一套系统性的平台构建。科研团队将海洋磷脂定向富集技术、海洋磷脂递送技术、磷虾油精制技术整合为海洋磷脂靶向递送平台,攻克鲜虾冷萃、药用级磷脂辅料国产化替代、海洋磷脂临床应用三项关键技术,并牵头启动磷虾油质量评价与海洋磷脂药用辅料团体标准研制。从基础原料到递送系统,从实验室验证到行业标准,一条围绕海洋磷脂的科研闭环正在成形。
从南极磷虾到高纯磷脂,从肠道吸收到血脑屏障穿透,这条路径上的每一步,都在重新定义海洋生物资源的科研价值。当深海里的分子开始学会“找路”,海洋医药的科研叙事,正在被改写。

The 2026 Greater Bay Area Science Forum will be held in Guangdong, Hong Kong and Macao from October 31 to November 2. Huang Hongyu, vice president of the Guangzhou Branch of the Chinese Academy of Sciences, said that during the forum, the institutes affiliated to the Chinese Academy of Sciences will sign more than 20 cooperation projects with Guangdong enterprises, covering cutting-edge fields such as energy, advanced manufacturing and biomedicine.

The 2026 Greater Bay Area Science Forum press conference was held in Guangzhou. Wang Yueqin, director of the Guangdong Provincial Department of Science and Technology, said that Guangdong is promoting the collaborative innovation of Guangdong, Hong Kong and Macao into the 2.0 stage to achieve all-round and in-depth collaboration from the flow of factors to projects, platforms, talents, industry and finance.

Researchers from the Chengdu Institute of Biology, Chinese Academy of Sciences, systematically analyzed the evolutionary history of unique terrestrial animals on the Qinghai-Tibet Plateau and surrounding areas, revealing a new mechanism for the formation of animal diversity in the Earth's "Third Pole." Relevant results were published in the Proceedings of the National Academy of Sciences on October 27.

On the night of October 22, a 7.0-magnitude earthquake occurred in Nagchu Baqing County, Tibet. The China Earthquake Administration quickly launched a Level 2 emergency response, dispatched 72 experts to the earthquake area, set up monitoring equipment in alpine areas above 4,800 meters above sea level, and carried out earthquake damage surveys and intensity assessments to provide data support for earthquake relief.

The China Earthquake Administration released the "7.0-magnitude earthquake intensity map of Baqing, Tibet". The highest intensity of this earthquake was 9 degrees. The 9 degree area covers an area of about 449 square kilometers and involves many towns and villages in Tibet and Qinghai provinces.

The China Earthquake Administration officially released a 7.0-magnitude earthquake intensity map in Baqing County, Nagqu City, Tibet. The highest intensity of the earthquake was IX. The macro and micro epicenter was located in Maru Township. The VI area and above covered an area of about 35,145 square kilometers, involving 2 provinces, 3 cities, 9 counties and 43 towns.
