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.

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

目的观察重组人表皮生因子(rhEGF)对眼表上皮修复的影响及羊膜移植治疗翼状肉的疗效。方法对36例患者40眼的翼状肉施行肉切除－羊膜移植术,术后随机分为(rhEF治疗组(20眼)和药物赋型剂对照组(20眼),分别观察两组角膜上皮愈合速度和结膜上皮覆盖羊膜植片的愈合速度,对全部患者随访3-12个月。结果rhEGF治疗组术后角膜上皮愈合速度[(74983±1998)μm/h]显著高于对照组[(59372±17.197)μm/hP＜0.01];rhEGF治疗组结膜上皮愈合速度[(36.584±7.888)μm/h显著高于对照组[(29．181±5.450) μmh,P＜0.01]。随访全部病例未见复发,结论rhEGF可有效促进眼表上皮的损伤修复,羊膜移植为治疗翼状肉的较好方法。

胫骨延长后骨痂直径与新生骨预后关系的临床分析

目的探讨胫骨延长后骨痂直径与新生骨预后的关系.方法 1996年1月～2001年12月,对68例胫骨延长者测量达所需延长长度时的骨痂直径,计算骨痂直径率(callus diameter ratios,CDR);统计拆除外固定架后2～4周时新生骨发生骨折例数及畸形角度,比较骨折和成角畸形与CDR的关系.结果拆除外固定架前胫骨前屈角度5度以上畸形19例,其中11例发生骨折;拆除外固定架后胫骨出现5度以上畸形6例,其中2例骨折;其余43例胫骨延长骨痂正常愈合.计算CDR值:CDR值小于80% 23例,其中发生新生骨骨折13例,成角畸形5度以上者21例;CDR在81%～85%之间6例,成角畸形5度以上4例;CDR值超过86% 39例,无畸形或新生骨骨折.结论胫骨延长时CDR小于80%时,容易发生新生骨骨折和畸形;CDR大于85%时,无新生骨骨折和畸形发生;两组间具有统计学意义(P＜0.05).CDR是判断骨痂能否正常愈合较为理想的检测指标.
