研究目的:

评估对于糖尿病足溃疡创面,与传统换药、手术方法相比,分别采用羊膜微型支架、应力-牵张可调控的皮肤软组织外扩张技术是否能够缩短创面闭合周期,提高创面闭合率。

随机方法(请说明由何人用什么方法产生随机序列):

采用随机区组设计方案,由主要研究者进行。 (1)根据创面大小将患者分类为微型羊膜支架移植/常规换药和皮肤软组织外扩张/常规手术两大类别,分别进入各自大类的试验组或对照组。 (2)确定区组长度和两个组的所有可能排列:设区组长度为4,则试验组和对照组两组所有可能的排列为6。 (3)给每种可能排列的区组分配抽样号码; (4)用抽签方法随机排列上述区组分配的号码。查随机数字表任意选择起始数,并按照从小到大排序得出上述区组分配的号码。 (5)将观察单位按事先编好的病例号从1号开始按顺序进入上述抽签后得到的区组号码顺序的各区组。

Randomization Procedure (please state who generates the random number sequence and by what method):

A randomized block design scheme was adopted and carried out by the main investigator. (1) According to the size of the wound, the patients are classified into two categories: micro-amniotic membrane stent transplantation/conventional dressing change AND external soft tissue expansion/conventional surgery, and enter the
