Application of four diagnostic methods in Treatise on Exogenous Febrile Diseases / 中华中医药杂志

Based on the study of four diagnostic methods in Treatise on Exogenous Febrile Diseases,this dissertation analysed the cause of differentiation of syndrome unavailable,and indicated that:differentiation of syndrome unavailable resulted from multi-reasons.The patients who had symptoms and signs but all the modern physics and chemistry index were normal,the data get from traditional four diagnostic methods were useful to discriminate and estimate diseases.Modern physics and chemistry index can help in improving exactitude,but we cannot ignore traditional diagnostic methods.

Effect of nerve growth factor on neuronal apoptosis after spinal cord injury in rats / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To explore the molecular mechanism of the protective effect of nerve growth factor (NGF) on injured spinal cord.</p><p><b>METHODS</b>The posterior T(8) (the 8th thoracic segment) spinal cords of 60 Wistar rats were injured by impacts caused by objects (weighing 10 g) falling from a height of 2.5 cm with Allen's way. Solution with nerve growth factors (NGF) was given to 30 rats (the NGF group) through a microtubule inserted into the subarachnoid cavity immediately, and at 2, 4, 8, 12 and 24 hours after spinal cord injury (SCI) respectively. Normal saline (NS) with same volume was given to the other 30 rats (the NS group) with the same method. And 5 normal rats were taken as the normal controls. The expression of bcl-2 and bax proteins in spinal cord was detected with immunohistochemistry. The apoptotic neurons in spinal cord were measured with terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end-labeling of DNA fragments (TUNEL) staining.</p><p><b>RESULTS</b>The positive expression of bcl-2 protein was strong in the normal controls, but decreased in the NS group, and increased significantly in the NGF group as compared with that of the NS group (P<0.01). The positive expression of bax protein was also strong in the normal controls, but increased in the NS group, and decreased significantly in the NGF group as compared with that of the NS group (P<0.01). Apoptotic neurons were found in the NS group, and they decreased significantly in the NGF group as compared with that of the NS group (P<0.01).</p><p><b>CONCLUSIONS</b>NGF can protect the injured nerve tissues through stimulating the expression of bcl-2 protein, inhibiting the expression of bax protein and inhibiting the neuronal apoptosis after SCI.</p>

Effects of nerve growth factor on neuronal nitric oxide production after spinal cord injury in rats / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To explore the protective effects of nerve growth factor (NGF) on injured spinal cord.</p><p><b>METHODS</b>The spinal cord injury (SCI) model of Wistar rats was established by a 10 gx2.5 cm impact force on the T(8) spinal cord. NGF (60 microg/20 microl) was given to the rats of the treatment group immediately and at 2, 4, 8, 12, 24 hours after SCI. The level of neuronal constitutive nitric oxide synthase (ncNOS) and the expression of ncNOS mRNA in the spinal cord were detected by the immunohistochemistry assay and in situ hybridization method.</p><p><b>RESULTS</b>Abnormal expression of ncNOS was detected in the spinal ventral horn motorneuron in injured rats. The levels of ncNOS protein in the NGF group were significantly lower than those in the normal saline group (P<0.05 ). The ncNOS mRNA expression was found in the spinal ventral horn motorneuron in injured rats and the expression in the NGF group was significantly decreased compared with that in the normal saline group (P<0.01).</p><p><b>CONCLUSIONS</b>NGF can protect the injured tissue of the spinal cord by prohibiting abnormal expression of nitric oxide synthase and the neurotoxicity of nitric oxide.</p>

Effects of nerve growth factor on N-methyl-D-asparate receptor 1 after spinal cord injury in rats / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To explore the effects of the nerve growth factor (NGF) on N-methyl-D-asparate receptor 1 (NMDAR 1) after spinal cord injury.</p><p><b>METHODS</b>Spinal cord injury of Wistar rats was performed with Allen's method by a 10 gx2.5 cm impact on the posterior T8 spinal cord. NGF was given to the rats of the treatment group via subarachnoid space tube at once, 2, 4, 8, 12 and 24 hours after spinal cord injury, respectively. The expression of NMDAR1 mRNA in spinal cord was detected by in situ hybridization.</p><p><b>RESULTS</b>Rare expression sequence of NMDAR1 mRNA was found in rat spinal cord of the normal group. A strong expression sequence of NMDAR1 mRNA was found in rat spinal cord of the normal saline group. The expression of NMDAR1 mRNA in the NGF group was significantly decreased as compared with that in the normal saline group (P=0.01).</p><p><b>CONCLUSIONS</b>NGF can relieve damage of injured spinal cord by prohibiting the expression of NMDAR1 mRNA.</p>

Transpedicular Fixation Combined with Mixed Transpedicular Structural and Cancellous Bone Graft for Severe Compressed or Burst Thoracolumbar Spinal Fractures / 中国微创外科杂志

Objective To explore the efficacy of transpedicular fixation combined with mixed transpedicular structural and cancellous bone granule graft for the treatment of severe compressed or burst thoracolumbar spinal fractures.Methods From January 2001 to January 2008,18 cases of severe compressed or burst thoracolumbar spinal fractures was treated with transpedicular fixation of spondylolisthesis and fracture(SF) or atlas fixation(AF) combined with mixed transpedicular structural and cancellous bone granule graft in the compressed vertebral body.Results In this group,no injuries to the spinal cord or nerves occurred.The mean blood loss was 50-300 ml(average 80 ml).The mean operation time was 100-180 min(mean 120 min),and the mean postoperative hospital stay was 12 to 30 days(14 days on average).Follow-up was available in 18 cases for a mean of 24 months(5-72 months),all the patients achieved satisfying recovery of the height and physiological curve of the vertebral body: 17 of the cases had normal height and physiological curve;in the other patient,the natural curve was partly destroyed;no patient had loosing and disrupted internal fixation.According to preoperative Frankel evaluation,1 case was classified as Frankel A,1 Frankel B;5 Frankel C,3 Frankel D,and 8 Frankel E before the operation;while postoperative classification showed 1 case of Frankel B;1 cases of Frankel C,and 16 cases of Frankel E.Conclusions Transpedicular fixation combined with mixed transpedicular structural and cancellous bone granule graft is safe and effective for the treatment of severe compressed or burst thoracolumbar spinal fractures.
