Methods: The primary PAEC had been cultured and passage with porcine autoserum. PAECs were plated in 96-well microculture plates, and incubated with 5%AB normal human serum, 5% heat-inactivated FCS and 5% no heat-inactivated FCS for 6 days respectively, then the survival rates were detected by MTT chromatic test and expression of heme oxygenase 1 (HO-1) was observed by immunohistochemical method after these PAECs had been incubated with 25% NHS for 2 hours.

以猪自体血清原代培养PAEC并传代，接种于96孔板后分别以5%正常人血清、胎牛血清和补体灭活的胎牛血清诱导6d，加入25%正常人血清，以MTT比色法检测细胞的存活率，并以免疫组化的方法观察各组HO-1的表达情况。

Inferior petrosal sinus extends from the posterior part of the cavernous sinus and courses along the clivus laterally, in IPS sulcus. It usually leaves cranial cavity through the jugular foramen and eventually joins the jugular bulb or the internal jugular vein.

岩下窦起自海绵窦后端，走行在斜坡两侧的IPS沟内，通常经颈静脉孔出颅，最终汇入颈静脉球或颈内静脉，沿途接收多条静脉的注入，与颅神经Ⅵ、Ⅸ、Ⅹ、Ⅺ关系密切。

Methods Nineteen bone impacted and unerupted teeth in 18 cases selected by orthopantomograph were scanned by 3DX-CT with 1.0 mm slice thickness. Images obtained by 3DX-CT (horizontally, sagittally, coronally) were analyzed after multi-plane reconstruction and 3D reconstruction including the angle of the bone axis impacted and unerupted teeth; maximum radius of the coronal teeth; distances between the tooth and the cortical bone around; distances to the neighboring tooth roots and nerve forum canal; the thickness of the bone tissue, etc.
