AIM To observe the curative effects of Modified Buzhong Yiqi Decoction (Codonopsis Radix,Astragali Radix,Atractylodis macrocephalae Rhizoma,ect.) on perioperative period of intertrochanteric fractures in elderly patients with Qi deficiency and blood stasis type.METHODS One hundred and twenty cases of elderly intertrochanteric fractures were randomly divided into treatment group and control group,60 cases in each group.All patients underwent closed fracture reduction and proximal femoral nail anti-rotation (PFNA) fixation.During the perioperative period,the control group only received conventional treatment,while the treatment group received conventional treatment and Modified Buzhong Yiqi Decoction once a day.The levels of interleukin-6 (IL-6),interleukin-10 (IL-10) and tumor necrosis factor (TNF-α) of both groups in preoperative and in the 1st day,the 7th day,the 14th day of postoperative were observed and compared.The complications and the curative effects according to the Harris score also were observed and compared between the two groups.RESULTS In preoperative,there was no significant difference in levels of IL-6,IL-10 and TNF-α between the two groups (P ＞ 0.05).The levels of IL-6 and TNF-α in the 1 st day of postoperative in the control group were significantly higher than those in the treatment group (P ＜0.05,P ＜0.01).And the levels of IL-10 were similar between the two groups (P ＞0.05).In addition,in the 7th day and the 14th day of postoperative,the levels of IL-6,IL-10 and TNF-α in both groups were all decreased,moreover,the descent degree in treatment group was more significant than those in the control group (P ＜ 0.05,P ＜ 0.01).The treatment group had the lower incidence of complications and the higher curative effects than those in the control group,both differences were statistically significant (P ＜0.05).CONCLUSION Modified Buzhong Yiqi Decoction applying to the perioperative period of femoral intertrochanteric fractures in elderly patients with Qi deficiency and blood stasis,can effectively reduce the perioperative inflammatory response,reduce the incidence of postoperative complications,and improve the curative effects.So it has a positive effect on the rehabilitation for the traumatic patients and is worthy of clinical promotion.
