感染患者血清可溶性细胞间粘附分子含量的变化及其对脑梗死的影响

目的：探讨感染合并脑梗死患者血清可溶性细胞间粘附分子（sICAM-1)的变化及临床意义。方法：采用双抗体（ELISA）法测定50例感染合并脑梗死患者血清中sICAM-1的含量，并与30例脑梗死患者和30例健康人对照。结果：感染合并脑梗死患者急性期血清sICAM-1的水平明显高于对照组。结论：感染合并脑梗死时sICAM-1的表达明显升高，sICAM-1水平的增高加重了脑梗死的发生发展。

隐性脊柱裂排尿功能异常的临床特征

目的：研究伴有排尿功能障碍的隐性脊柱裂患者临床特征。方法：总结41例有明显排尿功能障碍的隐性脊柱裂患者临床资料。以18岁为界，将患者分为儿童组和成人组，所有患者均接受X线检查，除4例儿童外，均接受普通尿流动力学检查。结果：儿童组发病高峰年龄在1～2岁，主要临床表现为持续性原发性遗尿，部分伴有尿频、尿急及轻度急迫性尿失禁现象；成人组发病高峰年龄在18～26岁，主要临床表现为尿频、尿急、排尿前踌躇、排尿困难、遗尿等。结论：隐性脊柱裂患者常有排尿功能异常表现，出现症状的高峰时间为出生后及青春发育期后。X线、CT、MRI和尿流动力学等检查在隐性脊柱裂排尿功能障碍的诊断和治疗方案制定中有重要地位。     

A Synergistic Effect Between PG490-88 and Tacrolimus Prolongs Renal Allograft Survival in Monkeys

This study was undertaken to determine if PG490-88 and tacrolimus (Tac) act synergistically to prevent renal allograft rejection in monkeys and to explore possible mechanisms of synergy between these agents. MHC-mismatched renal allografts were transplanted into cynomolgus monkeys after bilateral nephrectomy. Recipients were divided into the following groups: (i) no treatment; (ii) PG490-88 (0.03 mg/kg); (iii) Tac (1 mg/kg); (iv) PG490-88 (0.01 mg/kg) + Tac (1 mg/kg) and (v) PG490-88 (0.03 mg/kg) + Tac (1 mg/kg). Through synergy PG490-88 and Tac inhibited anti-CD3/PMA-induced T-cell proliferation and IFN-gamma expression in vitro. Tac monotherapy only marginally prolonged survival (27 +/- 3.2 days), while the combination of PG490-88 and Tac significantly prolonged graft survival to a median of 99 days (PG490-88 at 0.03 mg) and 38.5 days (PG490-88 at 0.01 mg/kg). Prolonged survival correlated with inhibited IgM production as well as reduced T-cell infiltration, IL-2 protein expression and NF-AT/NF-kappaB activity. We conclude that PG490-88 and a subtherapeutic dose of Tac significantly prolong renal allograft survival in monkeys through the synergistic inhibition of T-cell activation and a decrease in IFN-gamma production and NF-AT/NF-kappaB activity.     

肝癌经导管动脉灌注化疗栓塞术疗效的MR扩散加权成像动态研究

目的探讨MR扩散加权成像(DWI)在原发性肝癌经导管动脉化疗栓塞术(TACE)疗效动态评价中的作用。方法在1.5TGE Signa Twin speed MR机上,取扩散敏感梯度因子(b值)为0及800s/mm2,利用固定参数组合的自旋回波-平面回波(SE-EPI)序列对首次行TACE治疗的25例肝癌肿块分别于术前24~48h、术后36~48h、术后7~10d、术后30~38d内各进行1次DWI,对每次的图像进行后处理,计算出每例肝癌每个时点的表观扩散系数(ADC值),对各个时点的ADC值进行对比研究,并结合第1次TACE术后与第2次TACE术前肿瘤的血管造影染色及碘油沉积的改变判断肿瘤的复发情况。结果术前24~48h、术后36~48h、术后7~10d、术后30~38d组的ADC值分别为(1.376±0.012)×10-3mm2/s、(1.598±0.012)×10-3mm2/s、(1.723±0.012)×10-3mm2/s、(1.684±0.012)×10-3mm2/s。术后各组肝癌组织的ADC值较术前明显升高(P<0.05);术后7~10d、术后30~38d组的ADC值较术后36~48h组明显升高(P<0.05);术后30~38d的ADC值较术后7~10d组明显降低(P<0.05)。将第1次TACE术后与第2次TACE术前的造影片及碘油沉积片对比见术后30~38d ADC值下降的肝癌病例都有不同程度的复发,ADC值下降明显的复发也最为明显。结论利用MR DWI技术对肝癌组织的ADC值进行动态观察,可以评价肝癌TACE术后癌组织的坏死、复发情况。     

用结合^131碘和化疗药物的明胶微球作肝动脉...

Nine patients with inoperable hepatoma were treated by using hepatic arterial embolization 131I and chemotherapeutic agent gelatin microsphere (131I-CA-GM). The emission CT after operation detected that the microspheres were concentrated on tumor area. The ratio between the radioactivity in tumor and that in liver was 4.1:1. A case died of ictopic embolization; the others survived 3, 4, 5, 19, 24, 7, 8, and 12 months respectively. Three of them were still alive. 131I-CA-GM has triple anticarcinogenic actions, including the arterial occlusion, targeting chemotherapy and internal radiation. The microspheres can selectively accumulate in the tumor artery and can be easily traced by gamma-camera or emission CT. 131I-CA-GM is a hopeful embolic agent for the treatment of liver cancer, but some problems about ectopic arterial embolization should be further studied.     

血液流变学数据库的建立及其应用

This hemorheological data base was established with an Apple II computer. The covering technique was applied to deal with its lacks of memories. This data base had a mutual administration system and complete managing functions including inputting, inquiring, printing, transferring, revising functions and so on. More than twenty hemorheological parameters involving apparent viscosities of whole human blood, plasma viscosity, viscoelasticity and thixotropy indices, were saved in the way of paging mode. Meanwhile, this data base had a common mathematical statistics system in recently medical use. It included monovariable linear and nonlinear regressions, t-test, multiple linear regression, cluster analysis etc. Therefore, this data base can be conveniently utilized to analyze the hemorheological data comprehensively. Besides the establishment of normal hemorheological indices, this data base equipped a primary method of quantitative diagnosis through hemorheological indices, it gave a new method to diagnose some diseases and to observe their curing process.
