Ankle sprains are orthopedic clinical common disease, accounting for joint ligament sprain of the first place. If treatment is not timely or appropriate, the joint pain and instability maybe develop, and even bone arthritis maybe develop. The mechanism of injury of ankle joint, anatomical basis has been fully study at present, and the diagnostic problem is very clear. Along with the development of science and technology, biological modeling and three-dimensional finite element, three-dimensional motion capture system,digital technology study, electromyographic signal study were used for the basic research of sprain of ankle. Biomechanical and kinematic study of ankle sprain has received adequate attention, combined with the mechanism research of ankle sprain,and to explore the the biomechanics and kinematics research progress of the sprain of ankle joint.

OBJECTIVETo discuss the relative association of soft tissue tension and cervical physiological curvature chang in patients with scapula muscle fasciitis.

METHODSFrom February 2012 to December 2012,29 patients with scapula muscle fasciitis were investigated. There were 10 males and 19 females with an average age of 27.77 years old (ranged from 22 to 40 years old). Routine AP and lateral cervical X-rays were done in all patients. Cervical lordosis was measured according to Borden's method and the pain point tension was measured by soft tissue tension meter. Finally,perform statistic analysis to bove data.

RESULTSLateral X-rays showed 9 cases were normal cervical lordosis, 18 cases were cervical lordosis decreased, 2 cases were cervical lordosis increased. The regression equation of cerical lordosis changes D(Y) and soft tissue tension displacement D0.5 kg (X) was Y = -15.069 + 3.673X.

CONCLUSIONThere is linear relationship between soft tissue tension and cervical physiological curvature change. With the soft tissue tension increases, the cervical lordosis trend to decrease.

OBJECTIVETo set up a venous congested flap model to study the mechanism of necrosis through long-term microcirculation observation.

METHODSA specially deviced chamber was assembled to one side of the ears in an adult white rabbit, about 7 approximately 10 days after the operation the congested flap model was made and the microcirculatory status of the flap was dynamically observed under a vivo-microscope for a long time.

RESULTSThe venous crisis phenomenon of flap was well studied and the microcirculation of the flap was observed carefully, finally the variational rule of the congestion flap microcirculation was made clear.

CONCLUSIONSThe model could well simulate the venous crisis flap in clinic, and the microcirculation could also be observed for a long time.

Objective To explore the clinical outcome of using modified great toe wrap-around flap to reconstruct degloved thumb and fingers.Methods Eighteen patients were involved.Based on different types of injury,four procedures were carried on for reconstructing degloved thumb and fingers:①Unilateral modified great toe wrap-around flap to reconstruct 9 degloved thumbs of distal proximal level and 3 degloved fingers of proximal interphalangeal joint level.②Unilateral modified great toe wrap-around flap with second toe medial flap to reconstruct 2 total degloved fingers.③Bilateral modified great toe wrap-around flap to reconstruct 2 thumbs.④Bilateral modified great toe wrap-around flap and second toe medial flap with neurolized super thin anterolateral thigh flap to reconstruct 12 degloved fingers.This wrap-around flap carried with entire nail.A triangle flap was reserved at medial plantar of great toe.Results All free flaps were survived in one stage.Fifteen patients were followed up for 8 to 25 months.The contour of reconstructed digit was as same as contralateral digit with satisfactory motion arc and sensation.There was no extensive scar in donor toe.The width of medial plantar triangle flap increased significantly.All patients could walking,running,jumping without restricted.Conclusions With reconstructed by modified great toe wrap-around flap,degloved thumb or finger can be promised with excellent contour and function outcome.In the meantime,the loss of donor foot can be expected to minimal.This procedure is one of the best ways for reconstructing degloved thumb and finger.

Objectives To explore the effect of erythromycin on glutathione hormone (GSH) and γ-glutamyl cysteine synthetase (γ-GCS) in premature newborn rats exposed to hyperoxia, to study the intervention effect of erythromycin on hype-roxia-induced lung injury. Methods One-day old preterm SD rats were randomly divided into four groups:control group, eryth-romycin group, hyperoxia group, erythromycin+hyperoxia group. Hyperoxia group and hyperoxia+erythromycin group were continuously exposed to oxygen (oxygen concentration>0.85), control group and erythromycin group were in room air. Via cau-dal vein, the preterm rats was injected with erythromycin in erythromycin group and hyperoxia+erythromycin group, sodium chloride in control group and hyperoxia group daily. After 1,7,14 day(s) of hyperoxia (or air ) exposure, the preterm SD rats of four groups were killed, whole lung of these rats were isolated and histological changes were observed by hematoxylin-eosin (HE) staining, GSH andγ-GCS of pulmonary tissue homogenate were detected by double antibody sandwich enzyme linked im-munosorbent assay. Total lung RNA was extracted andγ-GCS mRNA was detected by reverse transcription polymerase chain re-action. Results The results showed that:After 1 and 7 day(s) of exposure, the expression of GSH、γ-GCS andγ-GCS mRNA in four groups showed significant differences(P<0.05). Among them, GSH expression in erythromycin + hyperoxia group was higher than that in the other three groups in 1,7,14 day(s) of exposure with significant differences (P<0.05);GSH expression in erythromycin+hyperoxia group and hyperoxia group reached the peak after 7 days of exposure. The expression ofγ-GCS andγ-GCS mRNA in erythromycin+hyperoxia group and hyperoxia group were higher than the other two groups after 1and 7 day(s) of exposure, the expression ofγ-GCS mRNA in erythromycin+hyperoxia group were higher than that of hyperoxia group with significant differences (P<0.05). Conclusions The expressions of GSH andγ-GCS in the lung of premature SD rats were abnor-mal by oxidation outbreak. Erythromycin may increase the activity ofγ-GCS, improve the anti-oxidation ability of GSH, and al-leviate hyperoxia mediated lung injury in premature rats.
