北京時間10月23日，據浙江大學醫學院附屬第二醫院消息，人工真皮的研究取得突破性進展，人工真皮的存活時間縮短到了7至10天，比國外産品強度高生命力更強。

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.

　　浙醫二院燒傷科主任韓春茂教授告訴作者，人工真皮的研究國外其實早就有了，美國就有類似的産品，但價格昂貴，而且人工真皮裏沒有血管，所以存活時間需要三周時間。在這麼長的時間內，移植的地方可能再次受到感染，那麼病人出院的時間也會延長。

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.

　　目前浙醫二院團隊研究出來的人工真皮，就是在以往的基礎上加入了一個高分子編織網的材料，不易變形，強化了整個真皮支架，使得血管存活的時間大大縮短，機械強度更高。用通俗的話來説，就是人工真皮會更緊致、牢靠，不易撕裂。而其中的高分子材料都是可吸收、可降解的，等病人的皮膚組織長好了以後，這些材料也就逐步地降解、排出體外。

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.

　　“人的真皮主要由細胞和細胞外基質成分組成，其中大部分都是膠原，而目前我們的人工真皮主要就是由膠原和高分子材料組成，這和真皮的相似度達80%，已經算是很相近的了。經過大動物的實驗以後，根據不同的時間點觀察它的癒合力，癒合後的收縮率等等一些情況，發現得到效果的確比國外的人工真皮增加了一個強度，使得它血管化增加了，當時看到這樣的結果，內心十分澎湃。”韓春茂對作者説。

“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，項目進展順利。人工真皮産品已通過型式檢驗，進入臨床試驗階段還需要2到3年時間。

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.
