依达拉奉用于重型颅脑损伤急性期的疗效观察

目的通过监测神经元特异性烯醇化酶（NSE）的变化情况来探讨依达拉奉对重型颅脑损伤急性期患者的治疗效果。方法60例重型颅脑损伤急性期患者随机分为治疗组（30例）和对照组（30例）,前者在常规治疗的基础上加用依达拉奉治疗,后者采用常规治疗,观察两组治疗前、治疗后1、3、5、7d血NSE变化情况及21d患者GCS评分情况。结果两组患者治疗后,NSE均明显下降（P〈0．05）,治疗3d后NSE水平两组间比较差异有统计学意义（P〈0．05）;治疗21d后两组GCS评分比较差异有统计学意义（P〈0．05）;两组患者用药期间未见有严重不良反应发生。结论依达拉奉治疗重型颅脑损伤,可以降低患者外周血NSE水平,减轻脑细胞的损伤,不良反应少。     

HIF and fumarate hydratase in renal cancer

Hereditary leiomyomatosis and renal cell cancer is a recently described hereditary cancer syndrome in which affected individuals are predisposed to the development of leiomyomas of the skin and uterus. In addition, this clinical entity also can result in the development of biologically aggressive kidney cancer. Affected individuals harbour a germline mutation of the fumarate hydratase (FH) gene, which encodes an enzyme that catalyses conversion of fumarate to malate in the Kreb's cycle. Thus far, proposed mechanisms for carcinogeneis associated with this syndrome include aberrant apoptosis, oxidative stress, and pseudohypoxic drive. At this time, the majority of accumulating data support a role for pseudohypoxic drive in tumour development. The link between FH mutation and pseudohypoxic drive may reside in the biochemical alterations resulting from diminished/absent FH activity. These biochemical derangements may interfere with oxygen homeostasis and result in a cellular environment conducive to tumour formation.
