Methods: A total of 48 patients with diabetic lower limb ulcer who were treated in the Endocrine Department of the hospital between January 2016 and January 2017 were divided into the control group and research group by random number table, 24 cases in each group. Control group received vacuum sealing drainage, and research group received vacuum sealing drainage combined with intermittent insulin flushing. The differences in the expression of inflammatory factors and apoptosis genes in the wound exudate were compared between the two groups before and after treatment. Results: Before treatment, the differences in the inflammatory factor contents and apoptsis gene expression in wound exudate were not statistically significant between the two groups of patients. After treatment, inflammatory factors IL-6, IL-1β, TNF-α, CRP, VCAM-1 and FGF2 contents in wound exudate of research group were lower than those of control group;apoptosis gene Bcl-2 mRNA expression in wound exudate of research group was higher than that of control group while Bax, p53 and Fas mRNA expression were lower than those of control group. Conclusions: Vacuum sealing drainage combined with intermittent insulin flushing can effectively reduce the local inflammatory response and promote the granulation cell proliferation in wound of patients with diabetic lower limb ulcer.展开更多

The expression of HIF-1α, angiogenesis molecules, inflammatory response cytokines and apoptosis molecules in keloid samples normal skin tissues were detected.Results: HIF-1α, VEGF165, Flt-1, Flk-1, Ang-1, Tie-2, PGE2, PGF2 , MIF, Livin and Survivin mRNA expression in keloid of pathology group were significantly higher than those in normal skin tissue of control group while TSG-6, Caspase-3, Caspase-7 and Caspase-9 mRNA expression were significantly lower than those in normal skin tissue of control group;HIF-1α mRNA expression was positively correlated with VEGF165, Flt-1, Flk-1, Ang-1, Tie-2, PGE2, PGF2 , MIF, Livin and Survivin mRNA expression, and negatively correlated with TSG-6, Caspase-3, Caspase-7 and Caspase-9 mRNA expression.Conclusion:HIF-1α is highly expressed in keloid and can promote angiogenesis and inflammatory response and inhibit apoptosis.展开更多
