阴股沟皮瓣显微解剖学特征及其在组织修复功能重建中的应用

目的：明确阴股沟皮瓣的显微解剖基础，为临床应用此皮瓣提供解剖依据。资料来源：应用计算机检索Medline1991-01／2005-01的相关文章，检索词“pudendal-thigh flap，micranatomy”，并限定文章语言种类为English。并且手工检索《中文科技资料目录一医药卫生）1998-01／2005-01的相关文章，检索途径：分类途径。 资料选择：对资料进行初审，并查看每篇文献后的引文。纳入标准：①随机对照的基础及临床试验。②无论是否为单盲，双盲或非盲法。排除标准：重复性研究或综述性文章。 资料提炼：共检索到42篇相关文章，21篇文献符合纳入标准，排除的21篇文献为内容陈旧或重复。 资料综合：阴股沟区动脉血液供应充足，并且位置均比较恒定，尤以阴部外动脉最为恒定。静脉回流丰富，神经支配可靠。阴股沟皮瓣是位于股内侧上方与会阴部之间的无毛区域，上界平耻骨联合上缘水平，下界为两侧坐骨结节连线，内侧界为阴囊或大阴唇外侧缘，外侧界为股内侧皱襞，自阴囊（唇）外侧缘向大腿内上方延伸约5cm包括的范围。该区动脉血液供应丰富，计有阴部外动脉，闭孔动脉前皮支，阴囊（唇）后动脉的外侧支，旋股内侧动脉的皮支，股内侧的主要动脉支，以及来自阴部内动脉的肛动脉（直肠下动脉）等，并且位置均比较恒定，其中尤其以阴部外动脉最为恒定。在阴股沟区，阴囊（唇）后动脉与旋股内动脉、闭孔动脉前支及阴部外动脉的分支存在广泛的吻合并在内收肌内侧以上的深筋膜层形成血管网。进入阴股沟区的多支血管相互吻合成网。阴股沟区静脉回流丰富，神经支配可靠。 结论：阴股沟皮瓣血运丰富，解剖简便易行，切取方便，供区隐蔽，再造性器官外形及恢复神经感觉均取得较为理想的效果，是一种值得推广的方法。     

Stimulation of inositol phosphate formation in cultured human retinal pigment epithelium.

Several hormones, neurotransmitters, and neuropeptides were screened for the ability to stimulate inositol phosphate formation in cultured human retinal epithelial (RPE) cells. Carbachol, vasopressin and thrombin were found to be effective. Treatment of RPE cells with all three agents produced increases in inositol monophosphate, inositol bisphosphate and inositol trisphosphate in the presence of 10 mM LiCl. Carbachol stimulated a 4-fold increase in the total of inositol phosphates at 1 mM. Studies with cholinergic antagonists showed a rank order of 4 DAMP greater than QNX greater than pirenzepine greater than methoctramine, suggesting the presence of M3 muscarinic receptors. Vasopressin gave a 2.5-fold stimulation at 10 microM. Agonists of vasopressin were also tested and gave differential responses. Studies using a V1 agonist (PIOVP) and a V2 agonist (DAVP) showed DAVP matching the level of stimulation elicited by vasopressin whereas treatment with PIOVP only reached 50% of the vasopressin response. These data suggested the presence of V2 receptors in the RPE cells. Several proteases were tested for their ability to stimulate RPE inositol phosphates. Thrombin caused a 7-fold increase in inositol phosphate formation at 1 U/ml, whereas trypsin and plasmin elicited smaller responses (approximately 2-fold). The thrombin effect was blocked by the thrombin-specific inhibitor, hirudin, but not by other protease inhibitors. Several mediators of inflammation such as bradykinin, histamine and serotonin were also tested, and they were ineffective in stimulating inositol phosphate turnover in the RPE cells.

A comparative study on therapeutic method of traumatic epidural hematoma

Objective： To explore the therapeutic methods, surgical indications and clinical practice of minimally invasive surgery on traumatic epidural hematoma （EDH）. Methods： Retrospective study was made on 135 patients with traumatic EDH admitted into our hospital from June 2002 to August 2005. Sixty-five patients were treated with mini-invasive negative pressure drainage （treatment group）, 70 patients with comparable condition used traditional craniotomy （control group ）. The mean time of operation, average days in hospital, expenditure and prognosis of two groups were recorded and analyzed. Results： There was no significant difference in therapeutic efficacy between two groups. Patients in treatment group had a shorter hospital stay and less expenditure than those in control group. Conclusion： Mini-invasive negative pressure drainage is simple, effective, economical and applicable to some traumatic EDH patients.
