Methods:Taking 156 sufferers of auriclar keloid at the orthopaedics department of the Southwest Hospital under the Third Military Medical University from June, 2008 to June, 2011 as the research subject, this research carried out retrospective analysis and summary of different surgical methods with the clinical data of subseque nt treatments, including medicament, radiotheropy, pressure, etc. Results:There was no auricular cartilage necrosis and deformation in the total of 156 cases. It was found that 134 cases were cured in a year of postoperative follow-up, getting the care rate to 85.9%. The treatment was effective on 20 cases, with the effective rate of 12.8%, while it was ineffective on 2 cases, with the ineffective rate being 1.3%. However, two cases showed tendency towards recurrence, which were treated effectively by non-surgical methods like local hormone injection. There was neither recurrence nor apparent hyperplasia of hypertrophic scars on the rest cases, with the auricle and the earlobe in good shape. Conclusion:By auricular keloid excision and stripping surgery, surgical suture tension was reduced. Glucocorticoid and radiotherapy were instantly applied to inhibit pyperplasia of cicatrical tissue. Subsequently, pressure, anti-scarring drugs and silicone membrane were adopted to ensure fine postoperative apperance and reduce recurrence. These methods were proved to be effectiveand they provided systematic and effective treatment for auricular keloid.展开更多

The results show that 23.1% of trihalomethane formation potential （THMFP） and 68% of haloacetic acid formation potential （HAAFP） can be removed by BAC, respectively. Under the same conditions, the removal rates of the same substances were 12.2% and 13-25% respectively only by GAC process. Compared with GAC, the high removal rates of the two formed potential substances were due to the increasing of bioactivity of the media and the synergistic capabilities of biological degradation cooperating with activated carbon adsorption of organic compounds. BAC process has some advantages such as long backwashing cycle time, low backwashing intensity and prolonged activated carbon lifetime, etc.展开更多

In mammals, most discriminative light touch sensation is mediated by the Aβ low-threshold mechanoreceptors. Cell bodies of Aβ low-threshold mechanoreceptors are located in the dorsal root ganglia and trigeminal ganglia, which extend a central projection innervating the spinal cord and brain stem and a peripheral projection innervating the specialized mechanosensory end organs. These specialized mechanosensory end organs include Meissner＇s corpuscles, Pacinian corpuscles, lanceolate endings, Merkel cells, and Ruffini corpuscles. The morphologies and physiological properties of these mechanosensory end organs and their innervating neurons have been investigated for over a century. In addition, recent advances in mouse genetics have enabled the identification of molecular mechanisms underlying the development of Aβ low- threshold mechanoreceptors, which highlight the crucial roles of neurotrophic factor signaling and transcription factor activity in this process. Here, we will review the anatomy, physiological properties, and development of mammalian low- threshold Aβ mechanoreceptors.展开更多
