河南省病毒性肝炎血清流行病学研究

Role of Ultrasound B in Diagnosis and Clinical Treatment of CranialOrbital Communicating Tumor

目的：了解我省各型肝炎的感染状况，为制定肝炎防治策略提供依据。方法：采用不等比例多阶段整群系统随机抽样，在全省选择１３个市县，３９个村（或市居委会），对１８９０个家庭的５８９８名成员进行调查和采取血样，血清采用放射免疫和酶联免疫方法检测甲、乙、丙、丁、戊各型肝炎病毒的感染标志。结果：全省甲、乙、丙、丁、戊肝的感染率分别为８９８％、６４２％、５０％、１２％、８６％。结论：我省各型肝炎病毒的感染分布各有规律，依此提出了河南省病毒肝炎的防治策略。

Objective: To invastigate the dignostic method of cranialorbital communicating tumor(COCT) with ultrasound B for its clinical diagnosis and treatment. Methods: The ultrasound graphies were directly got from orbit,skullcavity paranasal sinuses via the probe placed on the eyelid, or on the temperal skin be there temperal bone erosion. Results: According to their residental and invasive location, 46 cases of COCT were divided into the following five categories: ①CranialOrbital 19 cases, ②cranialorbitalnasal 3 cases, ③orbitalcranial 7 cases, ④Cranialorbitalextracranial 16 cases, ⑤nasalcranial 1 case. 32 case sunder went surgical removal with its approaches varied depending on its ultrasound B classification, total removal 30 cases,the other 2 cases subtotal. Conclusion: ultrasound B show a high reliability in the diagnosis of COCT,and selecting surgical approach according to the residental and invasive location of majorty part of the tumor manifested by ultrasound B graphy can significantly increase the total removal rate of COCT
