  • REVIEW AND CLINIACL APPLICATION OF END-TO-SIDE ANASTOMOSIS OF PERIPHERAL NERVE

    OBJECTIVE: To review the methods of end-to-side anastomosis in repair of peripheral nerve injury and to analyze the difficulty faced. METHODS: By index of recent literature, the kind of experimental model, observation criteria and the clinical data were collected and analyzed. RESULTS: For different methods of end-to-side anastomosis in repair of peripheral nerve defect, the clinical outcomes were reported differently. The clinical application was fewer. There was lack of case summary and assessment criteria. CONCLUSION: The superiority of end-to-side anastomosis made it necessary to further study the mechanism and improvement of quality.

  • ADVANCES IN TREATMENT OF ACHILLES TENDON INJURY

    OBJECTIVE: To review the anatomy, etiology, therapy strategy of Achilles tendon injury and its related advances in recent years. METHODS: The related articles in recent years were extensively reviewed. RESULTS: There still were many arguments about the effect of corticosteroid on the treatment of tendon disease. Fluoqmnolone was found to be related with Achilles tendon injury. Acute rupture of Achilles tendon could be treated with open operation, percutaneous repair, or conservative therapy. For old rupture, many kinds of operations could be selected. CONCLUSION: The growth factors found in recent years provide us with new prospect for future treatment of Achilles tendon injury.

  • THE EARLY PROTECTIVE EFFECTS OF BASIC FIBROBLAST GROWTH FACTOR ON ACUTE SPINAL CORD INJURY IN RATS

    OBJECTIVE To study the early protective effects of basic fibroblast growth factor(bFGF) on the experimental acute spinal cord injury. METHODS Thirty-four SD rats were randomly divided into three groups, and were subjected to contusion of thoracolumbar spinal cord. A thin plastic tube was placed in subarachnoid space below the injury level for perfusion. The bFGF-treated rats were received 20 microliters bFGF(containing bFGF 100 U) at once, 30 min, 1, 2, 3, 4, 6, 12, 24 and 48 hours after injury, and an equal volume of normal saline was given to the control group at the same time. The injured spinal cord was detected by morphological observation and biochemical index after injury. RESULTS The degree of ionic disorder in bFGF-treated rats was significantly ameliorated and the contents of H2O were also markedly decreased. The morphological finding showed that the damages of gray and white matter in bFGF-treated rats were slighter than those of saline-treated rats. CONCLUSION bFGF has some protective effects on the secondary lesion of early spinal cord injury in rats.

  • EXPERIMENTAL STUDY ON NERVE GROWTH FACTOR IN DROTECTING INJURED SPINAL CORD

    Thirty-five SD rats were divided into 3 groups, in which 5 rats were served as control. The other 2 groups, 15 rats in each received either NGF solution or normal saline. The injury at the level of T8 spinal segment of the rat in these two groups were made by dropping a weight of 10 g from a height 2.5 cm after a total laminectomly from T7-11 segments. A thin plastic tube was inserted into the subarachnoid space below the injured segments. NGF was introduced through the tube at intervals of 1, 2, 3, 4, 8, 12, 24, 48 hours in the NGF group, and normal saline in the normal saline group. At 4, 8, 24 hours following surgery, 5 rats in each group were sacrificed and the injured segments were resected for examination. The contents of water and calcium were measured by dry-wet method and atomic absorption spectroscopy. The result showed that total calcium and water contents in normal saline group were markly increased, however, the changes of these two parametere were not so prominent in NGF group. It was suggested that NGF play a role in protecting the spinal cord by maintaining the calcium level of the injured segment.

  • EXPERIMENTAL STUDY OF EXOGENOUS HIGH MOLECULAR WEIGHT NERVE GROWTH FACTOR MIXED WITH BLETILIA STRIATA GELATIN IN PROMOTING WOUND HEALING

    Abstract To observe the effect of exogenous high molecular weight nerve growth factor (HMW-NGF) mixed with bletilia striata gelatin (BSG) in the promotion of healing, the experiment was performed as follow: (1) In serumfree medium, the normal saline, BSG, HMWNGF, and BSG+HMW-NGF were added separately, and then, the chick embryo root ganglions (DRGs) were cultivated in the above prepared media and the axonal growth was observed. (2) 40 SD rats were divided into 4 groups. A wound of 2cm×2cm was made on the back of every rat. No treatment was given in group one. In other groups, BSG, HMW-NGF, andBSG+HMW-NGF were given separately to the wounds once daily. After 3 and 10 days, the wound area of every rat was measured, cells in the wounds were observed under light microscope and were calculated, and the time of healing was recorded. The results showed that BSG, HMW-NGF, especially BSG+HMW-NGF could promote wound healing.
