甲状腺机能亢进症围手术期的处理

为探讨甲状腺机能亢进症的手术治疗效果，对１０３８例甲状腺机能亢进症病人的围手术期处理情况进行了分析。结果：术后无１例发生甲状腺危象。术后２年以上者９８０例，均获随访（１００％），随访时间为２～１５年，治愈率为９９．１％；复发９例，占０．９％。     

刮治＋自体骨移植术治疗牙源性角化囊肿（附14例报告）

本文总结了１４例应用刮治和自体骨移植术治疗大型牙源性角化囊肿的方法，１４例植骨均成活，４例术后囊肿复发，再次手术，指出：与骨断切除治疗大型角化囊肿的方法比较，此法最大的优点是有利于保持患者面容和咀嚼功能，并对大型角化囊肿的手术原则，自体骨移植问题及手术注意事项进行了讨论。     

Gene Delivery to Human B-Precursor Acute Lymphoblastic Leukemia Cells

Autologous leukemia cells engineered to express immune-stimulatingmolecules may be used to elicit antileukemia immune responses. Genedelivery to human B-precursor acute lymphoblastic leukemia (ALL) cellswas investigated using the enhanced green fluorescent protein (EGFP) asa reporter gene, measured by flow cytometry. Transfection of the Nalm-6and Reh B-precursor ALL leukemia cell lines with an expression plasmidwas investigated using lipofection, electroporation, and a polycationiccompound. Only the liposomal compound Cellfectin showed significantgene transfer (3.9% to 12% for Nalm-6 cells and 3.1% to 5% for Rehcells). Transduction with gibbon-ape leukemia virus pseudotyped Moloneymurine leukemia virus (MoMuLV)-based retrovirus vectors wasinvestigated in various settings. Cocultivation of ALL cell lines withpackaging cell lines showed the highest transduction efficiency forretroviral gene transfer (40.1% to 87.5% for Nalm-6 cells and 0.3%to 9% for Reh cells), followed by transduction with viral supernatant on the recombinant fibronectin fragment CH-296 (13% to 35.5% for Nalm-6 cells and 0.4% to 6% Reh cells), transduction on human bonemarrow stroma monolayers (3.2% to 13.3% for Nalm-6 cells and 0% to0.2% Reh cells), and in suspension with protamine sulfate (0.7% to3.1% for Nalm-6 cells and 0% for Reh cells). Transduction of bothNalm-6 and Reh cells with human immunodeficiency virus-type 1 (HIV-1)-based lentiviral vectors pseudotyped with the vesicular stomatitis virus-G envelope produced the best gene transfer efficiency, transducing greater than 90% of both cell lines. Gene delivery intoprimary human B-precursor ALL cells from patients was then investigatedusing MoMuLV-based retrovirus vectors and HIV-1-based lentivirusvectors. Both vectors transduced the primary B-precursor ALL cells withhigh efficiencies. These studies may be applied for investigating genedelivery into primary human B-precursor ALL cells to be used forimmunotherapy.     

免疫层析法用于HCG快速检测的研究

目的：研制用于尿液HCG快速检验试纸条。方法：采用胶体金免疫层析分析方法。结果：检测灵敏度可达50IU／L，与高含量的LH、FSH、TSH均无交叉反应，检测214例临床样品，准确率为100％。结论：该方法简单、快速、特异性强，是检测尿液HCG较好的免疫学方法。     

Ⅱ孔型房间隔缺损直视修补术后心律失常的临床观察

210例Ⅱ孔型房间隔缺损术后发生心律失常90例,14种类型,共292例次,其中,室上性占96%。30例需药物治疗,93%的患者出院时恢复正常。本文着重分析心律失常的特点,讨论影响因素及预防措施。     

单发性双侧面横裂伴有家族遗传和染色体异常3例报告

报告3例单发性双侧面横裂伴有三代家族遗传史和相同的染色体异常核型,相同的对称性恒牙(胚)先天性缺如,并对面横裂的发病机制及病因学进行了讨论。这是一组极罕见的病例,在所涉猎的文献中,迄今尚未见相同报道,是否为一种新的综合征,目前尚不能定论,有待今后进一步探讨     

小肠平滑肌肿瘤的血管研究

目的：观察小肠平滑肌肿瘤血管形态。方法：对８例正常小肠标本及１０例（１５个瘤体）经病理证实的平滑肌瘤手术切除标本，采用血管造影、解剖镜观察、石蜡切片光镜观察及图像分析。结果：小肠平滑肌肿瘤血管丰富，共同特征是：供血动脉增粗，沿瘤蒂进入瘤中心，呈放射状分布、簇状增生、丰富吻合，形似“蜘蛛网”状。血管扭曲、中断，瘤体内造影剂池明显者提示平滑肌肉瘤。结论：小肠平滑肌肿瘤属多血供肿瘤，良、恶性之间血管存在一定特点。这有助于介入诊断及螺旋ＣＴ诊断。
