儿童原发性腹膜后恶性肿瘤的诊断与治疗

卵巢恶性肿瘤与血小板增多关系分析

目的探讨卵巢恶性肿瘤伴发血小板增多的临床规律。方法回顾分析98例卵巢恶性肿瘤患者的临床资料,26例合并血小板增多。结果血小板增多占26.5%,其中晚期(Ⅲ+Ⅳ期)占88.46%,晚期患者血小板偏高明显增多,且肿瘤切除后血小板下降。结论卵巢恶性肿瘤伴发血小板增多晚期患者多见,预后差,血小板增多可作为判断卵巢肿瘤恶性程度及术后随访的指标。     

Early computed tomographic scanning after resection of brain tumors in children

Enhanced and non-enhanced computed tomography (CT) brain scans were performed within 72 h of surgery on 21 children in whom brain tumors had been resected totally or subtotally, and scans were repeated at varying intervals thereafter. Biopsies of the resection margins were performed in 12 patients at the end of the surgical procedure. The immediate CT scan showed enhancement in the resection margin in 13 of the 21 patients and in 9 of the 13, the enhancement disappeared on follow-up scans. There was discordance between the results of immediate CT scan examination and the biopsies of the resection margins in 7 of the 12 cases. The advantages and disadvantages of an immediate postoperative scan versus a more delayed CT scan are discussed.

Papilliferous keratoameloblastoma

A case of papilliferous keratoameloblastoma is reported which is only the second ever documented. The patient was a 76-yr-old black woman with a large expansile multilocular radiolucency of the body, angle and ramus of the mandible. Histologically the lesion consisted of sheets of cystic follicles filled with necrotic debris and sometimes parakeratin. The vast majority of the follicles were lined by a papilliferous epithelium consisting of large rounded cells with centrally placed nuclei. True papillary projections with cores of connective tissue were also present. The remainder of the follicles were lined by a thin parakeratinising stratified squamous epithelium. Histological features characteristic of ameloblastoma were absent. Final classification of these lesions will have to await the reporting of further cases.     

拆方研究补中益气汤中黄芪 甘草及全方的免疫调节作用

目的　检测补中益气汤中黄芪、甘草及全方对病态机体的免疫调节作用。方法　分 7组检测全方中黄芪、甘草及全方缺黄芪、缺甘草组方对利血平制备的脾虚小鼠的 5项非特异性免疫功能的影响进行研究。结果　黄芪能使Hb明显升高 ,单味甘草对某些免疫功能不起作用甚至起抑制作用 ,缺甘草组方作用低于全方 ,全方能明显提高机体免疫功能。结论　黄芪是方中主要升高Hb药物 ;方中甘草起到特殊的调节作用。     

急性脑血管病肿瘤坏死因子-α的临床研究

目的：探讨肿瘤坏死因子-α（TNF-α）在急性脑血管病（ACVD）中的作用及其变化的临床意义。方法：选取95例ACVD患者，并设性别及年龄相匹配的血清对照组（20例）及脑脊液对照组（10例）。应用酶联免疫吸附法（ELISA）于发病后第1、3、7、14d测定血清和脑脊液中TNF-α。结果：①三种脑血管病患者血清TNF-α动态变化存在差异，脑出血和脑梗死组的峰值单间为发病后第3d，而蛛网膜下腔出血（SAH）组为第1d。②脑梗死患者血清TNF-α水平与梗死面积、神经功能缺损程度及病情恶化与否相关。③SAH组于发病后第1d、3d、7d脑脊液TNF-α值高于血清，14d时降至对照组水平并与血清无差异。结论：①脑梗死患者血清TNF-α的动态观察，可为临床预测梗死灶大小、神经功能缺损程度及病情恶化与否提供依据。②发病早期的脑梗死患者若CT未能显示病灶时，血清TNF-α的明显升高有助于临床诊断和治疗。③SAH患者脑脊液中TNF-α水平明显高于血清，进一步提示脑内神经组织可产生TNF-α。脑脊液中TNF-α的持续明显升高可能与SAH后脑血管痉挛有关。④TNF-α参与了ACVD的炎性反应过程，早期抑制TNF产生及抗炎性反应的治疗可能具有潜在的临床价值。
