    摘要:

    目的 本研究旨在探讨瑰及乳膏对压疮模型大鼠压疮肉芽组织中纤维粘连蛋白(fibonectin,FN)及碱性成纤维细胞生长因子(Basic fibroblast growth factor,BFGF)水平的的影响机制?方法 在128 只SD 大鼠中随机取32 只设为假手术组,另96 只均在大鼠双侧臀肌下埋置磁片外加磁铁片循环压迫缺血?再灌注的方法建立大鼠III 期压疮模型,4 d 后随机分为模型组?阳性对照组及瑰及乳膏组?假手术组和模型组外敷生理盐水纱布,阳性对照组外敷水胶体敷料,瑰及乳膏组在压疮部位外敷瑰及乳膏纱布?在治疗结束时统计压疮创面显效时间?压疮愈合速度和愈合率,并分别于治疗的第3?7?14?21 天时检测大鼠尾静脉血的血清炎症介质白介素?1β(interleukin?1β, IL?1β)?白介素?6(interleukin?6,IL?6)及C 反应蛋白(C?reactive protein,CRP)的水平,采用固相夹心法酶联免疫吸附实验检测压疮肉芽组织中FN 及BFGF 水平?结果 瑰及乳膏组显效时间和愈合时间较阳性对照组缩短,创面愈合率和愈合速度较阳性对照组提高,两组比较差异有显著性( P < 0. 05)?在治疗第14?21?28 天时,瑰及乳膏组静脉血CRP 及IL?1β?IL?6 均明显低于模型组和阳性对照组同期水平( P < 0. 05),BFGF 及FN 均明显高于模型组和阳性对照组同期水平( P < 0. 05)?结论 瑰及乳膏可能通过抑制压疮创面炎症介质IL?6?IL?1β 引起的炎症反应来减轻创面损伤,并提高BFGF 及FN 的合成来促进间质细胞的增殖和细胞外基质的合成,从而促进创面肉芽组织新生而加速创面组织修复?

    Abstract:

    Objective The purpose of this study was to investigate the effects of rose and cream on fiber pressure ulcer granulation tissue in rat models of pressure ulcer in terms of adhesion protein (fibronectin, FN) and basic fibroblast growth factor (BFGF) levels and their associated mechanisms. Methods A total of 128 SD rats were randomly selected for groups as follows: 32 in the sham operation group and the other 96 for groups with rat bilateral gluteal muscle implanted under the external magnetic disk compression cycle method of ischemia reperfusion to establish stage III model. After 4 days, these 96 were randomly divided into a model group, a positive control group, and a rose and cream group. The sham operation group and model group were treated with physiological Shiomizu Sabu, the positive control group was treated with hydrocolloids, and the rose and cream group had Guiji cream gauze applied to bedsores. At the end of treatment, bedsore wound healing rate and healing speed were analyzed upon treatment for 3, 7, 14, and 21 d, along with determination of the levels of rat tail vein blood serum inflammatory cytokines interleukin?1 beta ( IL?1β), IL?6, and C?reactive protein (CRP), and ELISA for FN and BFGF to determine the level of pressure ulcer granulation tissue, by the solid?phase sandwich method . Results The effective time and healing time of the rose and cream group were shorter than those of the positive control group, and the healing rate and healing speed of the cream group were higher than those of the positive control group ( P < 0. 05). Upon treatments for 14, 21, and 28 d, the rose and cream group venous blood CRP, IL?1β, and IL?6 levels were significantly lower than those of the model group and the positive control group ( P < 0. 05), while BFGF and FN were significantly higher than those of the model group and positive control group ( P < 0. 05). Conclusions Rose and cream may reduce wound injury by inhibiting the inflammation caused by the ulcer wound inflammatory mediators IL?6 and IL?1β, increasing the synthesis of BFGF and FN to promote cell proliferation and extracellular matrix synthesis of stromal cells, promoting wound granulation tissue of newborns, and accelerating wound tissue repair.
