人工真皮联合金扶宁对指腹皮肤愈合及细菌检出率的影响

Effect of artificial dermis combined with jinfu ning on skin healing and bacterial detection rate of finger abdomen.

目的:探索人工真皮联合重组人粒细胞巨噬细胞集落刺激因子(rhGM-CSF)凝胶剂(金扶宁)对皮肤缺损愈合及细菌检出率的影响。方法:收集我科收治的110例手指损伤患者,随机分为对照组和观察组,每组55例。对照组在彻底清创后直接进行人工真皮修复,观察组在清创后先给予重组人GM-CSF凝胶涂布创面,然后再进行人工真皮修复。比较两组患者的创面愈合情况、创面炎症情况和细菌检出率、炎症因子表达、随访情况和不良反应。结果:观察组治疗7、14、21、28 d的创面愈合率均显著高于对照组,差异有统计学意义(t=11.211,P=0.000;t=14.895,P=0.000;t=25.346,P=0.000;t=8.247,P=0.000)。观察组创面愈合的平均时间显著短于对照组,差异有统计学意义(t=14.197,P=0.000)。观察组各时间点创面炎症评分显著低于对照组,经组间、时间点、组间·时间点交互效应比较,差异均具有统计学意义(P<0.05),观察组的创面细菌检出率低于对照组,差异有统计学意义(χ2=4.68,P=0.030 5);两组的检出细菌主要为大肠杆菌、破伤风杆菌、真菌等。治疗前两组各指标无显著差异,治疗后两组炎症因子IL-1β、TNF-αIOD值均显著下降,且观察组显著低于对照组,差异有统计学意义(P<0.05)。治疗期间两组均未发生严重不良反应。结论:应用人工真皮联合金扶宁能够促进指腹皮肤软组织缺损创面愈合,还能有效抑制创面细菌感染,能够消炎、杀菌、减轻炎症感染,降低细菌检出率。

Objective: To explore the effect of artificial dermis combined with rhGM-CSF (Jinfuning) on healing of soft tissue defect of finger ventral skin and the influence of bacterial detection rate. Methods: 110 patients with finger injury admitted to the rehabilitation department of our hospital from January 2017 to June 2018 were collected and divided into the control group and the observation group according to the random number table method, with 55 cases in each group. The control group received direct artificial derma lrepairing after thorough debridement, while the observation group received recombinant gm-csf gel coating on the wound surface before artificial dermal repairing, Wound healing, wound inflammation, bacterial detection rate, inflammatory factor expression, follow-up and adverse reactions were compared between the two groups. Results: The wound healing rate of the observation group at 7, 14, 21 and 28 days after treatment was significantly higher than that of the control group (t=11.211, P =0.000);t =14.895, P =0.000;t =25.346, P =0.000;t =8.247, P =0.000). The wound healing time of the observation group was (19.7±2.3) d, and that of the control group was (27.4±3.3) d. The average wound healing time of the observation group was significantly shorter than that of the control group, and the difference was statistically significant (t=14.197, P=0.000). Observation group wound inflammation at each time point score was significantly lower than the control group, the group rooms, time points, point interaction effect between the comparison, the differences were statistically significant ( P <0.05), the observation group wound bacteria detection rate of 7.27%(4 cases): the control bacteria detection rate was 21.81%(12 cases), difference was statistically significant (chi-square=4.68, P =0.030 5), the observation group of bacteria detection rate was significantly lower than the control group;The bacteria detected in the two groups were mainly e. coli, tetanus bacillus and fungi. There was no significant difference in the indicators between the two groups before treatment, and the values of inflammatory cytokines il-1 and TNF-α IOD in the two groups were significantly decreased after treatment, and the observation group was significantly lower than the control group, with statistically significant differences ( P < 0.05). No serious adverse reactions occurred in either group during the treatment. Conclusion: The application of artificial dermals combined with jinfuning can promote wound healing of skin and soft tissue defect of finger abdomen, effectively inhibit bacterial infection of wound surface, reduce inflammation and infection, reducing bacterial detection rate.
