The aim of this study was to explore the protective effect of basic fibroblast growth factor (bFGF) on brain injury following global ischemia reperfusion and its mechanisms. Brain injury following global ischemia was induced by four vessels occlusion and systemic hypotension. Twenty-four rabbits were randomized into three groups: group A, only dissection of vessels; group B, intravenous infusion of normal saline after reperfusion for 6 h; group C, 30 μg/kg bFGF injected intravenously at the onset of reperfusion, then infused with 10 μg/(kg·h) for 6 h. Serum neuron specific enolase (NSE), S-100B, tumor necrosis factor-α(TNF-α), interleukin-1 (IL-1), interleukin-8 (IL-8) were measured before ischemia, 30 min after ischemia, 0.5, 1, 3, 6 h after reperfusion. Brain water content was determined and cerebral histopathological damages were compared. NSE and S-100B were increased 1 h after reperfusion and reached their peaks 6 h after reperfusion, but were much higher in group B than those in group C 3, 6 h after reperfusion. In groups B and C, TNF-a was increased after ischemia and IL-1 and IL-8 were increased significantly 0.5 h after reperfusion, then reached their peaks 6 h, 3 h, 6 h after reperfusion respectively. TNF-a and IL-8 at the time points of 1 h and 3 h and IL-1 at 3 h and 6 h in group C were correspondingly lower than those in group B. These indices in group A were nearly unchanged. There were less severe cerebral histopathological damages in group C compared with group B, but no difference in brain water content. It could be concluded that bFGF alleviates brain injury following global ischemia and reperfusion by down-regulating expression of inflammatory factors and inhibiting their activities. 相似文献

《庄子》思想蕴含的丰富性和复杂性,使它成为各种倾向共生的思想矿床。过去在讨论庄子的社会思想时,注重其避世和愤世的一面,而忽略了它矫治时弊、疗救社会的倾向。这就漏采了庄子思想中一些珍贵的矿藏,造成庄周学派的贬值。挖掘《庄子》书中的社会疗救思想,区分它杂揉在一起的精华和糟粕,有助于对庄子思想的全面认识和准确评价。 相似文献

As one of the oldest civilizations in the world, China boasts numerous ancient books which have not only witnessed the evolution of Chinese culture but also sustained the spirit of Chinese nation. However, a large number of existing ancient books, due to lack of efficient protection, are now aging, being destroyed or even lost. It is an urgent task for the government to rescue and protect those valuable ancient books in a comprehensive manner.[第一段] 相似文献

The coexistence of myelolipoma within adrenal cortical adenoma is extremely rare, for both tumors present usually as separate entities. There are only 16 such cases reported worldwide. To the best of our knowledge, the case we reported here is the first one of myxoid adrenal cortical adenoma associated with myelolipoma reported. A 32-year-old Chinese woman with 4-year history of hypertension was presented in our study. Computed tomography (CT) of the abdomen showed a large heterogeneously-enhancing mass (4.5cm in diameter) in the left suprarenal region. Clinical history and laboratory results suggest a metabolic disorder as Conn's syndrome. The patient underwent a left adrenalectomy, and a histopathological study confirmed the mass to be a myxoid adrenal cortical adenoma containing myelolipoma. The patient was postoperatively well and discharged uneventfully. In the present case report, we also discuss the etiology of simultaneous myelolipoma and adrenal adenoma associated with Conn's syndrome, and the methods of the diagnosis and differential diagnosis. 相似文献

China is the world’s earliest ceramic producer and porcelain inventor. As early as in the Xia Dynasty (ca. 2070 BC – ca. 1600 BC), green-glazed ceramics, quite similar to porcelain wares, appeared in China. By the 2nd century AD, ancient Chinese succeeded in producing porcelain wares with radiant glaze, transparent texture, low water absorption and clear resonance, at the 相似文献

威尼斯蓝天的妩媚和夜空的可爱是无法用语言来描绘的。在那明净的夜晚，湖面水平如镜，连星星的倒影也不会有丝毫颤动。泛舟湖心，四周一片蔚蓝、宁静，真是水天一色，使人如入甜美欲睡的绮丽梦境一般；空气是那么清澈、透明，抬头望去，这儿的星星似乎远比我们法兰西北部夜空中的星星要多。我发现，由于夜空到处布满星辰，那深蓝的夜色都变得暗淡了，融入了一片星辉。 如果你想领略一番这儿独有的清新和恬静，你可以在这迷人的夜晚去皇家花园附近，沿着大理石台阶往下，直到运河边上。要是那里镀金的栅栏已经关上，那人可以乘坐一种名叫… 相似文献
