氟伐他汀对缺血性脑卒中患者的疗效观察及护理措施

Objective To explore the effect and nursing main points of fluvastatin on the patients with cerebral arterial thrombosis. Methods Eighty-five patients with cerebral arterial thrombosis were randomly divided into three groups. Group Ⅰ was the negative control group. Group Ⅱ was the conventional-dose therapy group and group Ⅲ was the high-dose therapy group. Each group was treated with related therapy and care. The blood lipids in all groups were tested before the treatment, 4 weeks, 12 weeks and 24 weeks after the treatment; the carotid intima-media thickness (IMT) were measured by the Germany SEQUOIAS-512-B ultra machine before the treatment and 24 weeks after the treatment; At the same time, the side effects of fluvastatin were recorded. Results The results of blood lipid tests showed that the LDL, TC and TG in two treated groups were significantly decreased compared to negative control group (P<0.05). After treated for 24 weeks, the carotid intima-media thickness (IMT) in two treated groups were significantly reduced (P<0.05); the side effects of fluvastatin were infrequent and there was no significant different among the three groups (P>0.05). Conclusion The effects of different doses of fluvastatin on cerebral arterial thrombosis were significantly different. With the dose of fluvastatin increased, the serum LDL-L and TC reduced more obvious and the inhibition on carotid atherosclerosis shows more obvious, and the side effects did not increased.

维甲酸对涎腺腺样囊性癌实验性肺转移的抑制作用研究

本文利用已建立的涎腺腺样囊性癌肺转移动物模型，着重观察了Ａｃｃ－Ｍ细胞株经维甲酸体外处理后其在裸鼠肺部形成转移能力的情况。结果表明：１０μｍｏｌ／Ｌ、２０μｍｏｌ／Ｌ两种浓度有明显抑制转移作用，转移率及肺转移灶重量、数目和直径均较对照组有显著下降（Ｐ〈０．０５）；但抑制作用无浓度依赖性，揭示维甲酸对Ａｃｃ－Ｍ细胞株的作用位点是有限的。１０μｍｏｌ／Ｌ、２０μｍｏｌ／Ｌ可能是维甲酸抑制Ａｃｃ－Ｍ细胞株转移的最低饱和浓度。     

Effect of hepatitis C antibody screening in blood donors on post-transfusion hepatitis in Taiwan

A national screening programme for antibody to hepatitis C virus (HCV) in blood donors in Taiwan began in July 1992 using a second-generation immunoassay. To study the impact of this screening on post-transfusion hepatitis in Taiwan, a prospective study on post-transfusion hepatitis, that was started in 1987, was continued. As of June 1994, 245 patients who received a blood transfusion after July 1992 had completed a follow-up period for more than 6 months post-transfusion. Of them, seven (2.8%) recipients developed acute post-transfusion hepatitis. The hepatitis in six cases could not be attributed to infection by hepatitis A, B, C, D, E viruses or cytomegalovirus (CMV) or Epstein-Barr virus (EBV). The remaining patient seroconverted to both IgG and IgM anti-CMV. All seven patients recovered in 6 months without development of chronicity, and the mean peak alanine aminotransferase level was lower compared with that of the cases before anti-HCV screening (i.e. pre-July 1992). These results indicate that the current anti-HCV screening has effectively interrupted HCV transmission through blood transfusion in Taiwan.     

肝动脉化疗栓塞术治疗肝癌的临床与病理的联系

作者将9例肝动脉化疗栓塞术(HAE)后二期切除的肝癌标本,多处切片作病理检查,结合病人的临床过程分析HAE的治疗作用,肝癌包膜对HAE的影响,HAE的效果及HAE后手术的时机等。作者认为,HAE对肝癌的治疗效果是姑息性的,故HAE后应争取在30～60天内再手三术探查,争取切除肿瘤。否则,HAE后肝癌复发的可能性极大。     

重组人表皮生长因子对胬肉切除-羊膜移植后眼表上皮愈合速度的影响
