Clinical Effect of Internal Combined with External Fixation on Pelvic Fracture and Serum ALP, TNF-α and TGF-β Levels / 现代生物医学进展

ABSTRACT

Objective:To study the clinical effect of internal combined with external fixation in the treatment of pelvic fracture and its effect on the serum alkaline phosphatase (ALP),tumor necrosis factor-a (TNF-α) and transforming growth factor-β (TGF-β).Methods:Eighty-six patients with pelvic fractures admitted in our hospital from August 2014 to July 2015 were selected and divided into the observation group and control group according to the admission order.Conventional internal fixation was used in the control group,and the internal combined with extemal fixation was performed in the observation group.The clinical curative effect,operative time,blood loss,fracture healing time and incidence of complication were compared between two groups.The levels of serum ALP,TNF-α and TGF-β in the two groups were compared before and after treatment between two groups.Results:The excellent rate of observation group was significantly higher than that of the control group [81.40％ (35/43) vs 41.86％ (18/43)] (P ＜0.05).The operative time,blood loss and fracture healing time in the observation group were significantly shorter or less than those of the control group (P＜0.05).There was no significant difference in the serum ALP,TNF-α and TGF-β levels between the two groups before treatment (P＞0.05).After treatment,the serum ALP levels in the two groups were significantly higher than before treatment (P＜0.05).The levels of TNF-α and TGF-β were significantly lowe than those before treatment(P＜0.05),the ALP levels in the observation group was significantly higher than that of the control group (P ＜0.05),and the levels of TNF-c and TGF-β were significantly lower than those of the control group 0.05).The incidence of complications of observation group was significantly lower than that of the control group [0.00％ (0/43) vs 11.63％ (5/43)] (P ＜0.05).Conclusion:Internal and external fixation was effective and safe in the treatment of pelvic fractures,which could significantly increase the serum ALP level and reduce the levels of TNF-α and TGF-β.
