Active-specific immunotherapy for melanoma

Twenty-five patients with metastatic melanoma were treated with a therapeutic vaccine ("theraccine") consisting of allogeneic melanoma lysates and a novel adjuvant, DETOX (Ribi ImmunoChem Research, Inc, Hamilton, MT). Each patient received 200 antigenic units (20 x 10(6) tumor cell equivalents) subcutaneously on weeks 1, 2, 3, 4, and 6. Clinical responses included one complete remission, three partial remissions, and a long-term (17-month) stability. Two other patients had mixed responses, with partial remissions of numerous subcutaneous nodules. Sites of responsive disease included primarily the skin, but ileal, breast, and a liver metastasis also responded. Removal of residual lesions in patients with partial remissions, whose other lesions had disappeared during treatment, led to long disease-free survivals. The median duration of remission was 17 months, with four of the five responders alive for at least 24 months after treatment. An increase in precursors of cytolytic T cells (CTLs) correlated with clinical outcome, when complete, partial, and mixed responses and long-term stability were considered. The CTLs recognized melanoma-associated antigens on many cell lines, but not other types of tumor or normal lymphocytes. Skin-test reactivity to melanoma antigens and serum antibodies against the melanoma cells was unrelated to clinical response. Toxicity was minimal, restricted largely to minor soreness at the site of injection. Only five patients, four of whom were treated with repeated courses, developed severe granulomas. These results confirm that active-specific immunization with allogeneic lysates of melanoma administered with the adjuvant DETOX can induce immunity to melanoma, and can induce regressions of disease in a proportion of patients with metastatic disease with little toxicity.     

新工艺制备的β—TCP陶瓷小鼠肌肉内种植后的变化

目的：检测新工艺制备的β－磷酸三钙（β－TCP）的生物相容性,方法：将自制β－TCP植入小鼠股后肌袋。术后24,72h,1,2,4,8周分别取材做组织学检查,2,4周取材部分标本做扫描电镜（SEM）观察。结果：随着时间推移,β－TCP逐渐被纤维组织分割包围,但是无软骨,骨和坏死组织形成,结论：新工艺制备的β-TCP具有良好的组织相容性。     

Change of Coagulation Factor Ⅷ and Antithrombin Ⅲ Activity in Bank-Stored Blood

Blood storage and blood transfusion have beenimportantclinical work.In recentyears,the demandfor the quality of blood transfusion is getting higher.Great progress has been made in blood storage tech-nique and more and more reports on change in bloodcomponents during storage have been published.However,reports on dynamic changes in blood com-ponentsin bank- stored blood are stillrare.The paperinvestigated the dynamic change of blood componentsF :c and AT- in blood stored in blood bank un-der…     

视盘血管炎的治疗

目的:研究视盘血管炎的发病机制,病因,病程经过,治疗方法及预后.方法:系统治疗和观察了视盘血管炎46例,其中视乳头水肿26例、30眼,中央静脉血栓型20例、20眼.对患者视力、视野、眼压、视乳头改变、眼底荧光血管造影及血象等进行了检查.对视乳头水肿型行CT颅脑扫描,眼压测量和脑脊液检查以除外颅内病变.所有患者均予以抗感染和抑制免疫反应疗法.结果:患者均在18个月内治愈.视乳头水肿型视盘血管炎半数视盘颜色变淡.中央静脉血栓型25%患者视盘颜色变淡,但其视力不下降.全部患者视力均有不同程度地提高.结论:视盘血管炎是一种非特异性内源性血管炎,是对广泛性抗原的过敏反应,抗感染和抑制免疫反应可以缩短病程,提高视力,减少并发症.     

KATP通道开放剂KRN2391对离体大鼠心肌梗死范围的影响

目的：探讨ＡＴＰ敏感性钾通道（ＫＡＴＰ通道）开放剂ＫＲＮ２３９１（ＫＲＮ）对离体大鼠心功能及心肌梗死范围的影响。方法：用Ｌａｎｇｅｎｄｏｒｆｆ装置,观察不同浓度ＫＲＮ对冠脉灌流量及左心室压力的影响。应用离体大鼠双冠脉分别灌注芊４５ｍｉｎ缺血及２ｈ再灌注,观察药物对心肌梗死面积的影响。结果：ＫＲＮ在达到１ｕｍｏｌ／Ｌ浓度后冠脉灌流量明显增加,达２０ｕｍｏｌ／Ｌ时左室收缩压明显下降,用１ｕｍｏｌ／ＬＫ     

老年病人麻醉期间氧供需平衡的研究

目的:研究老年病人麻醉期间氧代谢变化,并分析其原因,提出保护老年病人麻醉期间氧供需平衡的方法.方法:选择上腹部手术老年病人(年龄＞65岁)30例,按数字随机法分为全麻组(n＝15)和硬膜外麻醉组(n＝15),并随机选择青壮年上腹部手术病人10例,作全麻对照组.监测麻醉期间老年病人氧供(DO2)、氧耗(VO2)、氧摄取率(ERO2)、混合静脉血氧饱和度(SVO2)和动脉血乳酸含量(ABL)等指标动态变化的情况.结果:老年病人全麻组与硬膜外麻醉组比较:前者麻醉诱导后至术毕DO2、VO2、ERO2均小于后者,并且SVO2、ABL均大于后者,它们之间均有显著性差异或非常显著的统计学意义(P＜0.05或P＜0.01).而老年全麻组与青壮年全麻对照组比较:前者DO2、VO2、ERO2小于后者,SVO2、ABL大于后者,而且它们之间也有显著性差异(P＜0.05).结论:上腹部手术老年病人全麻期间存在氧供需平衡障碍,出现明显的组织缺氧.根本的原因可能是老年病人微循环障碍的存在,而硬膜外麻醉有改善老年病人微循环障碍,纠正氧供需平衡失调的作用.     

二尖瓣脱垂的外科治疗

报道５７例二尖瓣脱垂（ＭＶＰ０不同术式的外科治疗效果。手术随机分为３组;传统的二尖瓣成形组,Ｇｏｒｅ－Ｔｅｘ线人工腱索替换组和瓣膜置换组。结果显示,Ⅱ组和Ⅲ组术后每搏二尖瓣返流量明显少于Ⅰ组。各组术后长期随访机能状况均明显改善。ＭＶＰ的外科治疗应首选二尖瓣成形;而Ｇｏｒｅ－Ｔｅｘ线人工腱索替换和人造瓣环盛开有方法安全可靠,其效果优于传统的腱索成形,并可避免瓣膜置换术后长期抗凝的并发症。
