Objective To comprehend the characters of sensory integration of children with brain injury and identify the effect of sensory integration training.Methods 127 children with brain injury were determined by the check form of sensory integration, Wechsler Preschool and Primary Scale of Intelligence (WPPSI), Wechsler Intelligence Scale for Children-China Recension (WISC-CR) and comprehensive function assessment for disabled children. These children were divided into the trial group (n=92) and control group (n=35). All children of two groups received rehabilitation training, but children of the trial group also received sensory integration training. The Results of them were compared before and after rehabilitation.Results The scores of the check form of sensory integration of the children with cerebral palsy were significantly higher than that of children with mental retardation (P<0.01). After rehabilitation training, the raising scores of comprehensive function assessment for disabled children of the trial group were significantly higher than the control group (P<0.01).Conclusion The ability of sensory integration are abnormal in children with brain injury. The sensory integration training can accelerate the comprehensive function of children with brain injury effectively.

BACKGROUND:Repair of large-area burns and severe post-traumatic skin defects has always been urgent clinical breakthrough technology bottleneck. With the development of tissue engineering, epidermal stem cel s are increasingly being used in tissue engineering, cel replacement therapy and genetic engineering. Therefore, the isolation and identification of epidermal stem cel s is becoming the research focus of concern.
OBJECTIVE:To review the research progress in biological markers of epidermal stem cel s.
METHODS:The Chinese Biomedical Literature database, CNKI database, China Academic Journals Ful-text database, PubMed database and EMbase database were retrieved for articles about specific markers of epidermal stem cel s using the keywords of“epidermal stem cel s, integrin, keratin, P63, CD71, telomerase, ACE, cx43, hoechst”in Chinese and English. Older theoretical perspectives and repetitive research were excluded.
RESULTS AND CONCLUSION:Final y, only 40 articles were included in result analysis. Epidermal stem cel s bring a new source for skin tissue repair. Epidermal stem cel s distribute in the fol icle eminence and basal layer of the epidermis. About 4%cel s in the basal layer, however, are stem cel s. Therefore, it is critical to correctly isolate, culture and identify skin stem cel s. As a reason, specific markers of epidermal stem cel s become a hotspot. Currently, a great progress in the biological markers of epidermal stem cel s has been made, but there is stil no absolute and proven marker for epidermal stem cel s. Most studies are focusing on integrin, keratin, P63, CD71, connexin 43, and telomerase. In addition, hoechst, CD90, CD98, CD200 have been reported recently. Each marker has its own shortcomings, and there are stil many problems that need to be solved.

The change of PKC activity and cytosolic free Ca 2+ induced by oxLDL and simvastatin in ASMC were measured by its ability to transfer phosphate from 32P-ATP to lysine-rich histone and flow cytometric analysis loading with the Ca 2+ dye fluo-3/Am, respectively. As a result, oxLDL increased total PKC activity in a dose-dependent manner with phase peaking at 14 min, then decreased slowly and maintained for at least 30 min, while oxLDL induced biphasic [Ca 2+]i responses including rapid initial transient phase and sustained phase. Removal of extracellular Ca 2+did not inhibit the rapid phase of oxLDL-induced rise in [Ca 2+]i, but abolished the sustained phase of [Ca 2+]i in response to oxLDL. Activity of PKC was markedly decreased and simvastatin did not impair the initial peak in response to oxLDL but significantly reduced the subsequent plateau phase when simvastatin was added. The results suggested that oxLDL can induce dynamic changes of signal transduction of PKC and cytosolic free Ca 2+in ASMC. The rapid initial transient phase was due to the mobilization of [Ca 2+]i from intracellular Ca 2+ pool and the sustained phase resulted from the influx of extracellular Ca 2+. The inhibition of PKC activity induced by simvastatin may contribute to the changes of intracellular Ca 2+.

Objective To evaluate the MR findings of normal and abnormal collateral ligament. Methods The MR findings of 56 normal and 36 surgically confirmed injured collateral ligaments were retrospectively reviewed and compared. Results The normal tibial and fibular collateral ligaments were hypointense string on both T 1 and T 2 coronal MR images, with an average length of 6.8 cm for tibial collateral ligament and 5.7 cm for fibular collateral ligament. 36 collateral ligaments were injured, including 18 tibial and 12 fibular collateral ligaments. Three cases (6 ligaments) had both tibial and fibularcollateral ligaments injuries. The injury of collateral ligament was classified as: Grade I (18 ligaments), Grade Ⅱ (11 ligaments), and Grade Ⅲ (7 ligaments). The complications of anterior cruciate ligament sprains (13 cases), posterior cruciate ligament sprains (9 cases), meniscal tears (12 cases), bony contusion and fracture (7 cases), and joint effusion (20 cases) were found in 25 patients(78%). Conclusion Coronal MR imaging can clearly demonstrate the structure of the knee collateral ligaments, accurately diagnose and classify the ligament injury, and correctly detect the complications. MRI should be used as a routine examining method for knee trauma.
