太极张三丰从口服到外用 雄激素性秃发治疗增加“局部靶向”新路径_我的网站
A | (ECNS) -- A joint research team from Shanghai and Hong Kong published a landmark study in the journal Science on Friday, revealing the mechanisms behind the heart's innate emergency blood-supply pathway. The discovery could lead to game-changing treatments for acute myocardial infarction. The 10-year collaborative project, jointly led by researcher Zhou Bin of the Center for Excellence in Molecular Cell Science at the Chinese Academy of Sciences (CAS) and Professor Kathy Lui of the Chinese University of Hong Kong, found that when major cardiac arteries are blocked during a heart attack, tiny capillaries – previously regarded as mere narrow “side paths” – are reprogrammed to remodel themselves into functional collateral arteries. These spontaneous new vessels act as natural bypass channels, rerouting blood around blocked sections to rescue damaged heart tissue. The finding overturns the long held belief that collateral arteries can only arise from pre existing arterial structures. The breakthrough paves the way for targeted therapies to stimulate the heart to grow its own life-saving networks, offering a promising new treatment direction for all types of ischemic heart disease.

随着医学界对雄激素性秃发发病机制认识不断完善，一种新的治疗思路正在临床逐渐形成——既然影响毛囊的重要雄激素代谢主要发生在头皮局部，那么药物是否也可以更加精准地作用于头皮?
8月22日，在上海举行的杨国亮皮肤病学大会上，多位毛发医学专家围绕这一问题进行了讨论。 专家介绍，多数雄激素性秃发患者并不存在明显的全身雄激素升高，其重要发病环节之一，是头皮毛囊局部的睾酮在5α-还原酶作用下转化为双氢睾酮，并持续作用于敏感毛囊。 传统非那雄胺主要采用口服方式，通过抑制5α-还原酶减少双氢睾酮生成。随着药物递送和制剂技术发展，过去一年，外用非那雄胺喷雾剂在中国批准上市，逐步进入临床应用，使雄激素性秃发的治疗在过去一年里由全身系统性用药进一步延伸到头皮局部用药。 这并非简单的“片剂变喷雾”，而是反映了皮肤科治疗逐渐走向精准化和局部化的趋势。 相关临床研究显示，外用非那雄胺喷雾剂型可以降低头皮局部双氢睾酮水平，并改善部分患者的毛发生长情况，同时对全身激素水平的影响相对较小。
