Method: The study was completed in the No. 1 Affiliated Hospital of Hebei North University in Zhangjiakou City, Hebei Province, China, from January 2001 to December 2013 by Analyzing the X-ray, CT scanning and MRI of 257 cases of the brucellar spondylitis retrospectively and comparing with the clinical imageology and pathology 332 cases of turberculosis of the spine diagnosed finally. Results: The brucellar spondylitis: The focuses usually locate in the lumbar vertebra and L4, 5 has the highest occurrence rate. The focuses are often small but multiple, and limited to the edge of the vertebra. Hyperostosis and osteoscterosis are usually found in the tissuses around the focuses. There are often new focuses in the newborn bones, and the destruction of intervertebral discs is usually slight. Hyperostosis and osteoscterosis might be found in the surfaces of the joints. The densites of the bones close to the focuses become high. There were less or no paravertebral abscesses but inflammational granuloma can be found frequently. Turberculosis of the spine: The focuses are usually located in the thoracic and lumbar vertebra, and are characterized by the destruction of the vertebra and the intervertebral discs, accompanied by the appearance of dead bones. In most cases, paravertebral abscesses and osteoporosis might be found. Conclusions: The specific manifestation of the clinical imageology can help to differentiate the brucelar spondylitis from the turberculosis of the spine.展开更多

In this study, a rat model of Alzheimer＇s disease was established after intracerebroventricular injection of β-amyloid peptide （25-35）. Subsequently the rats were intraperitoneally treated with osthole （12.5 or 25.0 mg/kg） for 14 successive days. Results showed that osthole treatment significantly improved cognitive impairment and protected hippocampal neurons of AIzheimer＇s disease rats. Also, osthole treatment alleviated suppressed long-term potentiation in the hippocampus of Alzheimer＇s disease rats. In these osthole-treated Alzheimer＇s disease rats, the level of glutamate decreased, but there was no significant change in y-amino-butyric acid. These experimental findings suggest that osthole can improve learning and memory impairment, and increase synaptic plasticity in Alzheimer＇s disease rats. These effects of osthole may be because of its regulation of central glutamate and y-amino-butyric acid levels.展开更多
