神经生长因子基因转染联合强化铁营养防治豚鼠爆震性聋的实验研究

Objective To study the protective effects of adenovirus-mediated human beta-nerve growth factor gene (hNGFβ) transfer combined with iron fortified nutrition on blast hearing damage in guinea pigs. Methods Deafness was induced by blast (172dB SPL) in 35 healthy guinea pigs. Seven days after noise exposure, 10 guinea pigs were inoculated with adenovirus-mediated hNGFβ (Ad-hNGFβ) into the perilymphatic space (the gene group), another 10 guinea pigs were given hNGFβ combined with iron fortified nutritional diet (the combination group), still another 10 guinea pigs were inoculated with artificial perilymphatic fluid (APF), and 5 guinea pigs served as control, given neither medicine nor noise exposure. Auditory brainstem response (ABR) threshold shifts were monitored in the guinea pigs before blast exposure and after gene transfer. Changes in cochlear morphology were examined with immunohistochemical and HE staining. Results One week after successful inoculation of hNGFβ, it was noted that Ad-hNGFβ protein was expressed in each turn of the cochlea, and its intensity was almost equal. After gene transfer in the combination group and the gene group, ABR threshold shifts at week 1 and 4 were significantly smaller than those of the APF group. HE staining showed that the number of the spiral ganglion cells in the combination group and the Ad-hNGFβ group was significantly higher than that of the control group after 4 weeks (P<0.01). Conclusions Ad-hNGFβ combined with iron fortified nutritional diet was effective in the prevention and treatment of blast hearing damage of cochlear hair cells.

蛛网膜下腔出血后迟发性脑血管痉挛的发病机制及治疗

蛛网膜下腔出血(SAH)是常见的脑血管意外,发病率高,可分为自发性蛛网膜下腔出血和外伤性蛛网膜下腔出血.自发性蛛网膜下腔出血多由于动脉瘤破裂造成的,可导致多种并发症,脑血管痉挛(CVS)是其最严重的并发症.蛛网膜下腔出血后脑血管痉挛是颅底动脉的一支或多支血管平滑肌的持续收缩,或血管损伤引起管腔形态学的变化,在动脉造影时表现出血管管腔狭窄,发生率高达30%～90%.早发性CVS出现于出血后,历时数分钟至数小时缓解,目前认为是SAH后流入脑脊液中的血液对脑血管的机械性刺激所致.暂时性或早发性CVS对脑血管功能影响不大.迟发性CVS发生于出血后4～15 d,7～10 d为高峰期,常引起严重的局部脑组织缺血或迟发性缺血性损伤,甚至导致脑梗死,成为致死和重残的主要原因.近年来随着发病机制研究的不断深入,治疗的种类和方法均有新的进展.
