Objective To observe the effect of shenfu injection on ischemia/reperfusion injury in skeletal muscle of rats. Methods To make a model of ischemia/reperfusion injury in skeletal muscle of rats, and observe the plasma level of LDH, CK, MDA and the change of MDA, MPO, W/D in the skeletal muscle. Result Shenfu injection can reduce the heightened plasma level of LDH, CK, MDA and MDA, MPO, W/D of the skeletal muscle, lighten the injury of the ultrastructure. Conclusion Shenfu Injection can protect ischemia/reperfusion injury in skeletal muscle.

BACKGROUND:Valgus knee deformity is rare in the clinic. The therapeutic effects of artificial knee arthroplasty are worse than varus knee deformity. There is no unified opinion for replacement approach, soft tissue release method and procedure and prosthetic choice at present.
OBJECTIVE:To summarize case data and to observe clinical effects of total knee arthroplasty for valgus knee deformity.
METHODS:Clinical data of 37 cases of valgus knee deformity (42 knees) undergoing total knee arthroplasty, who were treated by the same group of physicians in the First Department of Orthopedics, Gansu Provincial Hospital of Traditional Chinese Medicine from January 2010 to December 2012 were retrospectively analyzed. There were 11 males (13 knees) and 26 females (29 knees), at the age from 56 to 78 years, with an average age of 63.7 years. The differences in range of motion, femorotibial angle and Hospital for Special Surgery knee score were compared before and after replacement. Clinical effects of total knee arthroplasty for valgus knee deformity were evaluated.
RESULTS AND CONCLUSION:The postoperative fol ow-up lasted from 6 to 36 months. Knee joint range of motion increased from preoperative 68.5° to an average of postoperative 108.5°. Femorotibial angle reduced from preoperative 16.82° to postoperative 5.62° on average. The average Hospital for Special Surgery knee score increased from preoperative 39 points to postoperative 88 points (P<0.05). These results suggested that the curative effect of total knee arthroplasty for valgus knee deformity is proved. Total knee arthroplasty is an effective way to improve deformity.
