早期DSA检查对蛛网膜下腔出血的临床意义

蛛网膜下腔出血（subarachnoid hemorrhage，SAH）是临床发病率和死亡率均较高的急性脑血管病之一，并呈逐年增高趋势。随着神经介入影像学的发展，对急性SAH患早期（72h内1开展数字减影血管造影（digital subtraction angiography．DSA）检查，使SAH的早期病因诊断及病因治疗成为可能，患的预后也得到显改善。我院自2003年1月至2006年4月收治96例SAH患行早期DSA检查并给予相应的病因治疗．取得较好的临床疗效。现将有关资料与临床治疗总结报道如下。[第一段]     

Pathogenesis of congenital pyrimidine 5′ -nucleotidase | deficiency: A study on relationship among erythrocyte morphology, enzyme protein content and activity

Objective: To further explore the mechanism of congenital pyrimidine 5'-nucleotidase I deficiency. Methods; The samples were collected from the family members of a patient with P5'N- I deficiency. The enzyme activities were measured by UMP method and the enzyme proteins were quantified by ELISA while the morphology of peripheral blood cells was observed. Results: The enzyme contents reduced as their enzyme activities decreased in the family especially in four members. There was a significant positive correlation(r =0. 955) between the activity and the content of P 5'N- I . The count of the stippling cell was varied in the family. Conclusion.- One of the reasons for congenital P5' N- I deficiency might be the deficiency in the enzyme content. The morphology of peripheral blood erythrocyte may be an assistant diagnotic index. The P5'N- I activities and contents were measured simultaneously may be a effective method in clinic diagnosis.

Thyroid Artery Erosion by Esophageal Cancer: Management with Interventional Radiology

Management of upper gastrointestinal bleeding because of erosion of vessels by esophageal cancer may be challenging. We present herein the angiographic images of a 49-year-old patient who was admitted with massive bleeding from a tumor-eroded inferior thyroid artery. Attempts to control the bleeding by means of flexible endoscopy and insertion of a Sengstaken–Blakemore tube had failed. The diagnosis was impressively demonstrated by multislice computed tomography with intravenous contrast in the arterial phase and multiplanar reconstructions (computed tomography angiography) and by digital subtraction angiography. The bleeding was successfully treated with superselective catheterization and coiling of the eroded vessel.     

FR-Ⅲ型矫治器治疗上颌骨发育不足型Ⅲ类错的临床分析

目的　探讨替牙中期FR Ⅲ型矫治器矫治上颌骨发育不足型Ⅲ类错牙合患者骨骼、牙齿参数变化。方法　选择15例安氏Ⅲ类错牙合患者 ,在替牙中期使用FR Ⅲ型矫治器 ,治疗前、结束后均拍摄头颅侧位片 ,并对其进行测量分析。结果　通过上切牙唇倾、下切牙舌倾、下颌向后向下旋转 ,前牙可建立正常覆盖覆牙合关系。结论　替牙中晚期 ,FR Ⅲ型矫治器是治疗上颌骨发育不足型Ⅲ类错牙合的一种有效方法。     

王成荣治疗子宫内膜异位症“火热致瘀”理论探讨

王成荣研究员长于以中医药诊治子宫内膜异位症（EMT），根据其临床经验认为“火热致瘀”是EMT的基本病因、病机，且火热与瘀血互为因果、恶性循环，致使EMT病程缠绵不愈、反复复发。王老据此提出“清热解毒、化瘀散结”的治疗法则，为治疗EMT开辟了另一思路和理论。
