Objective To observe the effect of two reverse pedicle flap repaired soft tissue defect of the finger.Methods From April,2011 to March,2015,46 patients were randomly divided into two groups.Twenty-eight cases were performed by dorsal metacarpal artery flaps with cutaneous branches as pedicle and the 18 cases were performed by reverse the proper palmar digital artery dorsal branches island flap.The complication,survival rate,hand function and appearance were analyzed.Results The dorsal metacarpal artery flaps with cutaneous branches as pedicle and reverse the proper palmar digital artery dorsal branches island flap were an average follow-up of 18 and 15 months,all flaps survived.For fingertip defects,8 cases were repaired with as pedicle as the dorsal metacarpal artery flaps with cutaneous branches as pedicle while 16 cases were repaired with reverse the proper palmar digital artery dorsal branches island flap.Among them,complication included 2 cases of early venous congestion and 2 cases of superficial skin necrosis.One case of reverse the digital artery dorsal branches island flap blistered;the flap sensibility was good recovery.The two-point discrimination testing of dorsal metacarpal artery flaps with cutaneous branches as pedicle was from 6.0 to 9.0 mm (average of 7.1 ± 0.5 mm);the two-point discrimination testing of dorsal metacarpal artery flaps with cutaneous branches as pedicle was from 4.0 to 7.0 mm (average of 5.2 ± 0.4 mm),but there were differences in two-point discrimination and there was statistically significant (P ＜ 0.05).There was no significant difference between the two groups each finger interphalangeal joint activity compared with the healthy side.The study found that 10 cases of dorsal metacarpal artery flaps appearance was 5 mm higher than normal skin and 1 patient of reverse the digital artery dorsal branches island flap appearance was 5 mm higher than normal skin,the difference was statistically significant (P ＜ 0.05),the latter was better than the former,especially repaired fingertip defect.Conclusion Dorsal metacarpal artery flaps with cutaneous branches as pedicle and reverse the proper palmar digital artery dorsal branches island flap were safe and reliable,it is the ideal flap finger defects.For finger fingertip defect repaired reverse the proper palmar digital artery dorsal branches island flap is superior dorsal metacarpal artery flaps with cutaneous branches as pedicle.

Objective To study the protein expression levels of matrix metalloproteinases (MMPs)and their inhibitors in bone tissues of rat femoral head and to explore the relationship between necrosis of femoral head and glucocorticoid.Methods Twenty healthy adult SD rats were randomly divided into glucocorticoid group and control group,with 10 rats in each.Glucocorticoid group was treated with intramuscular injection of hydrocortisone twice a week.The control group received normal saline of the same volume.Four weeks later,bone tissues of left femoral head were collected from each group of rats for HE determination of femoral head necrosis.The expressions of matrix metalloproteinase-1 (MMP-1 ), matrix metalloproteinase-2 (MMP-2 ), tissue inhibitor of matrix metalloproteinase-1 (TIMP-1 ),and tissue inhibitor of matrix metalloproteinase-2 (TIMP-2 )at mRNA and protein levels were detected by RT-PCR and Western blot techniques,respectively.Results The expressions of MMP-1 and MMP-2 at mRNA and protein levels were higher in glucocorticoid group than those in the control group. However,TIMP-1 and TIMP-2 gene and protein expression levels were lower in glucocorticoid group (all P<0.05). Conclusion The expressions of MMPs in bone tissues of rat femoral head in early necrosis were increased,but their inhibitors had decreased expressions. We can draw the conclusion that glucocorticoid-induced necrosis of femoral head may be related to its regulation of the expression levels of MMPs and their related inhibitors.
