摘要：目的:探讨综合护理干预对糖尿病足溃疡愈合及创面修复因子的调控作用。方法:40例糖尿病足溃疡患者随机分为对照组和护理干预组,各20例,对照组采用内科常规护理,干预组采用湿润烧伤膏外敷换药和综合强化护理,比较两组患者在溃疡愈合速度、时间、换药次数、时间及疗效方面的差异,并检测各时间段肉芽组织中创伤修复因子的表达量。结果:干预组在换药次数、时间,创面愈合时间上均明显少于对照组(P<0.05);干预4周后,干预组疗效明显优于对照(P=0.00);干预组在第14、21、28天的b FGF、EGF、VEGF、PDGF、AEGs表达量与对照组比较,差异具有统计学意义(P<0.05)。结论 :综合护理干预能有效提高糖尿病足溃疡治疗的疗效,并能促进创面愈合修复因子b FGF、EGF、VEGF、PDGF的表达,抑制负性因子AEGs的生成。

摘要：目的研究湿润烧伤膏对SD大鼠深Ⅱ度烫伤创面的影响及作用机制。方法将60只SD大鼠制成深Ⅱ度烫伤模型,并按照随机数表法分为湿润烧伤膏组(30只),创面外用湿润烧伤膏换药治疗;磺胺嘧啶银组(30只),创面外用磺胺嘧啶银换药治疗。于烫伤后第3天和第7天通过免疫组化法观察CD31、Ki67在创面上的表达,作为创面肉芽组织增生情况的评判指标;测定大鼠烫伤创面愈合率,作为判断创面愈合情况的指标;采用荧光定量PCR法测定两组大鼠血小板源性生长因子及表皮生长因子的表达量。结果以愈合率达到95%为创面愈合,实验组创面平均愈合时间为17 d,对照组创面平均愈合时间为20 d,两组创面愈合率进行配对t检验,P<0.05,差异具有统计学意义。免疫组化法观察结果显示,实验组CD31及Ki68的表达均强于对照组。Real-Time PCR结果显示,实验组PDGF(血小板源性生长因子)在伤后1～7 d的表达量均强于对照组;EGF(表皮生长因子)在伤后3～10 d的表达量也均强于对照组。结论湿润烧伤膏能通过增加PDGF、EGF的表达促进创面血管新生及细胞增殖,加速上皮化进程,达到防止创面加深、促进创面愈合的作用。

摘要：目的：探讨全蝎软膏对糖尿病皮肤溃疡大鼠模型EGF、PDGF及其受体表达的影响及创面愈合的机理。方法：60只大鼠随机分为对照组、模型组、湿润烧伤膏组和全蝎软膏组，每组15只。建立糖尿病皮肤溃疡大鼠模型，干预后7天及14天，观察并比较大鼠创面愈合率和血清中表皮生长因子(epidenllal giiilllh factor, EGF)、血小板衍生生长因子(platelet-derived growth factor, PDGF)及其受体水平。结果：全蝎软膏组、湿润烧伤膏组与模型组7 d、14 d同时间点比较创面愈合率，差异有统计学意义(P<0.05或P<0.01)；全蝎软膏组、湿润烧伤膏组7 d、14 d同时间点比较，差异无统计学意义(P>0.05)。免疫组化结果显示，EGF的表达水平，全蝎软膏组、湿润烧伤膏组与模型组比较，7 d差异有统计学意义(P<0.05);14 d差异无统计学意义(P>0.05)。EGFR的表达水平，全蝎软膏组与湿润烧伤膏组、模型组、空白组7 d、14 d同时间点比较，差异无统计学意义(P>0.05)。PDGFB的表达水平，全蝎软膏组、湿润烧伤膏组与模型组7 d、14 d同时间点比较，差异有统计学意义(P<0.05)。PDGFRB的表达水平，7 d全蝎软膏组与湿润烧伤膏组、模型组、空白组比较，差异无统计学意义(P>0.05);14 d全蝎软膏组、湿润烧伤膏组与模型组比较，差异有统计学意义(P<0.05或P<0.01)。结论：全蝎软膏可影响糖尿病皮肤溃疡大鼠模型EGF、PDGF及其受体的表达，促进糖尿病创面愈合。

摘要：Background and objective: Vitamin K is a fat-soluble vitamin that plays an important role in the coagulation pathways of living organisms. A popular application of vitamin K has been used to help in the extravascular removal of blood from the skin. The aim of the present study was to test the wound healing effect of vitamin K and some common wound dressing agents available in Erbil city clinical settings such; the moist exposed burn ointment (MEBO) and the Cica silver spray to test their combination with vitamin K injections. Methods: Six groups of albino rats were used (6 rats in each group). Group M received Mebo ointment, Group Creceived Cica silver spray, Group K received Vitamin K injection, Group MK received Mebo ointment+vitamin K injection.Group CK received Cica silver spray +vitamin K Group, and Group N received no- treatment. The duration of the experiments was as 7, 14, and 21 days post wound surgery.The percentage of wound contraction was measured, and the blood serum was collected to test the level of transforming growth factor β (TGFβ) and platelet-derived growth factor (PDGF). Results: Data presented in our study showed that the best wound contraction percentage(99%) was obtained by the MK treated rats compared to the control group. Similar results were obtained fromTGFβ and PDGF data in which MK group showed a significant increase in the levels of these growth factors. Conclusion: The wound healing process is supposed to be due to an increase of TGFβ, PDGF, and enhanced fibroblast proliferation and neovascularization of tissues.
