北京时间10月23日，据浙江大学医学院附属第二医院消息，人工真皮的研究取得突破性进展，人工真皮的存活时间缩短到了7至10天，比国外产品强度高生命力更强。

On October 23rd, Beijing Time, according to the Second Hospital affiliated to Zhejiang University school of medicine, the study of artificial leather has a breakthrough, the survival time of artificial leather shortened from 7 to 10 days, has higher strength and stronger vitality than foreign products.

　　浙医二院烧伤科主任韩春茂教授告诉作者，人工真皮的研究国外其实早就有了，美国就有类似的产品，但价格昂贵，而且人工真皮里没有血管，所以存活时间需要三周时间。在这么长的时间内，移植的地方可能再次受到感染，那么病人出院的时间也会延长。

Professor Han Chunmao, the director of the department of burning and injury of the Second Hospital of Zhejiang University, told reporter that the study of artificial leather has been studied abroad. There are similar products in the United States, but they are expensive and there are no blood vessels in the artificial leather, so it takes three weeks to survive. In such a long time, the transplant may become infected again, so the patient will be discharged again.

　　目前浙医二院团队研究出来的人工真皮，就是在以往的基础上加入了一个高分子编织网的材料，不易变形，强化了整个真皮支架，使得血管存活的时间大大缩短，机械强度更高。用通俗的话来说，就是人工真皮会更紧致、牢靠，不易撕裂。而其中的高分子材料都是可吸收、可降解的，等病人的皮肤组织长好了以后，这些材料也就逐步地降解、排出体外。

At present, the team of the second hospital of zhejiang university has studied the artificial dermis, which is the material that has been added to a polymer woven net on the previous basis, which is not easy to deform. It strengthens the entire dermal scaffold, making the time of blood vessel survival greatly shortened and mechanical strength higher. In popular terms, it is the artificial dermis that is tighter, stronger and less prone to tearing. And the polymer materials are absorbable and biodegradable. When the skin tissue of the patient is well, the materials are gradually degraded and excreted.

　　“人的真皮主要由细胞和细胞外基质成分组成，其中大部分都是胶原，而目前我们的人工真皮主要就是由胶原和高分子材料组成，这和真皮的相似度达80%，已经算是很相近的了。经过大动物的实验以后，根据不同的时间点观察它的愈合力，愈合后的收缩率等等一些情况，发现得到效果的确比国外的人工真皮增加了一个强度，使得它血管化增加了，当时看到这样的结果，内心十分澎湃。”韩春茂对作者说。

“Human dermis is mainly composed of cells and extracellular matrix components, most of which are collagen. At present, our artificial dermis is mainly composed of collagen and macromolecule material. This is about 80 percent similar to the real skin, which is very similar. After the experiment of large animals, according to observe its healing forces at different points of time, the shrinkage rate after healing and so on, the results showed that the effect was more intense than that of foreign artificial dermis, which increased the vascularization. When I saw such a result, I feel excited.” Han Chunmao told reporter.

　　目前，项目进展顺利。人工真皮产品已通过型式检验，进入临床试验阶段还需要2到3年时间。

Now the project is progressing smoothly. The artificial leather products have passed the type inspection and it will take two to three years to enter the clinical trial stage.
