ABSTRACT
Objective:To study the regularity of clinical symptoms of sympathetic cervical spondylosis. Methods:A retrospective study was conducted on 110 patients with sympathetic cervical spondylosis admitted to the outpatient department from 2017 to 2019. The regularity of clinical symptoms of the patients was analyzed, including the sympathetic symptoms of different systems, the property of dizziness, the sequence, time interval and correlation of the symptoms, and whether the numbness of the limbs was accompanied by the symptoms and signs of cervical spondylotic radiculopathy and cervical spondylotic myelopathy. Results:The sympathetic symptoms were complex, involved in digestive system (71.82%), cardiovascular system (83.64%), respiratory system (63.64%), sweat gland (48.18%), eyes (81.82%), ears (60.91%), brain (68.18%) and limbs (70%), mainly sympathetic excitatory. The dizziness of the patients was mainly manifested as muddled brain (66.36%), a few patients were accompanied by external objects or their own rotation and sloshing (23.64%), and a very few patients showed external objects or their own rotation and sloshing (8.18%). Most patients complained chronic neck pain before dizziness and other sympathetic symptoms, accounting for 58.18%. The mean time for progression from neck pain to dizziness was (68.98±64.42) months. There were 77 patients complaining limb numbness, but none of them was found symptoms or signs of cervical spondylotic radiculopathy or cervical spondylotic myelopathy. It seemed to be a part of sympathetic symptoms in the limbs. The severity of dizziness was positively correlated with the course of disease (r = 0.610, P < 0.001), and was also positively correlated with the score of sympathetic symptom (r = 0.301, P = 0.004). Conclusion:The symptoms of sympathetic cervical spondylosis are complex. Muddled brain is the main symptom of dizziness, not vertigo. As the disease progresses, dizziness and sympathetic symptoms gradually worsen. Most sympathetic cervical spondylosis develops from cervical spondylosis. Cervical spondylotic radiculopathy or cervical spondylotic myelopathy may be the more severe forms of cervical spondylosis that develop on this basis。
ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of Ganhuang Injection (GHI) on reject reaction of xenograft.</p><p><b>METHODS</b>RT-PCR technique was used to detect the activated relevant gene expression in porcine endothelial cells (PEC), and 51Cr releasing method was used to test the killing and adhesion action of NK cells.</p><p><b>RESULTS</b>The normal human serum and human NK-92 cell could up-regulate the mRNA expressions of E-selectin and IL-1 alpha gene in PEC, showing the PEC activating action, GHI could inhibit these activated gene expressions. Cyto-toxic experiment showed that GHI could also inhibit the cytotoxicity of NK cell on PEC dose-dependently, which was in accord with its inhibition on adhesive action of NK on PEC.</p><p><b>CONCLUSION</b>GHI could inhibit not only the PEC activation in hyperacute rejection, but also the function of NK cells in delayed xenograft rejection.</p>

<p><b>AIM</b>To analyse the mechanism of corticosterone on the elevation of cytosolic free calcium ([Ca2+]i) induced by high-K+ in pheochromocytoma PC12 cells,</p><p><b>METHODS</b>The [Ca2+]i was real-time checked by fluorescence image system.</p><p><b>RESULTS</b>(1) When the cells were preincubated at 37 degrees C for 5 min in the presence of various concentration corticosterone and stimulated with 55 mmol/L KCl , an inhibitory effect of corticosterone on delta[Ca2+]i was observed in a concentration-dependent manner. (2) When PC12 cells were preincubated with various concentration of B-BSA at 37 degrees C for 5 min and stimulated with 55 mmol/L KCl, an inhibitory effect of B-BSA on delta[Ca2+]i was observed, which is also concentration-dependent manner. (3) The inhibitory effect of corticosterone and B-BSA could not be antagonized by RU38486 at 10(-4) mol/L. (4) cycloheximide could not block the inhibitory effect of corticosterone after pretreating cells at 10(-5) mol/L at 37 degrees C for 3 hours.</p><p><b>CONCLUSION</b>It is obvious that the locus of corticosterone action is on the plasmic membrane. The inhibitory effect of corticosterone is independent of protein synthesis and intracellular glucocorticoid receptor. The effect of corticosterone on [Ca2+]i is nongenomic action in PC12 cells.</p>
