目的 探讨乳腺癌接种后裸鼠后血清中基质金属蛋白酶2的含量变化,为诊断乳腺癌早期转移提供新的依据。方法 将乳腺癌细胞接种裸鼠成瘤后,观察乳腺癌成瘤过程,并采用酶联免疫吸附试验(ELISA)检测肿瘤形成过程中裸鼠血清中MMP-2含量的变化,并结合乳腺癌生物学行为进行分析。结果 乳腺癌MCF-7细胞在接种后第9天至第11天后,于接种部位出现肉眼可见肿瘤结节,随时间推移进行性生长,血清中MMP-2含量明显增高,血清中MMP-2的含量与肿瘤浸润深度、肿瘤组织Ⅳ型胶原分布、淋巴结转移关系密切。结论 乳腺癌动物模型血清中MMP-2含量变化与肿瘤浸润关系密切。测定血清中MMP-2含量可作为判断乳腺癌早期转移的临床观察指标之一。  相似文献

应用皮瓣移植治疗重度虎口挛缩的体会   总被引:1,自引:1,他引:0  
目的 总结几种皮瓣移植术治疗重度虎口挛缩的效果.方法 针对2000年9月至2009年3月收治的重度虎口挛缩的32例病例,应用超薄型髂腹股沟皮瓣、血管蒂逆行岛状皮瓣、神经营养血管蒂皮瓣及游离皮瓣予以治疗,皮瓣面积3.0 cm×5.0 cm~4.5 cm×8.0 cm,术后随访3~12个月,观察其治疗结果.结果 1例神经营养血管蒂皮瓣和1例超薄型髂腹股沟皮瓣远端部分坏死,后经游离植皮术创面愈合,其余皮瓣均完全成活,部分病例术后拆除克氏针固定后虎口有部分程度回缩,虎口角平均为70°(45°~80°),虎口宽度平均为50 mm(35~60 mm),为健侧的80%,挛缩得到明显改善,拇指可完成外展及对掌功能,握力较健侧略差,可完成日常生活及部分工作,但部分皮瓣感觉欠佳.移植皮瓣外形:超薄型髂腹股沟皮瓣外形良好,3例血管蒂逆行岛状皮瓣、1例神经营养血管蒂皮瓣及2例游离皮瓣术后再次行皮瓣修整术以改善皮瓣外形.结论 重度虎口挛缩可应用不同类型皮瓣予以治疗,应根据具体情况选择合适的治疗方式.  相似文献

温度对家兔骨骼肌细胞不可逆变性的影响   总被引:1,自引:0,他引:1  
目的:探讨不同温度下缺血家兔骨骼肌亚微观结构的变化与缺血时间的相关性.方法:设置10个不同温度组即35℃、30℃、25℃、20℃、18℃、15℃、12℃、9℃、6℃和4℃组(每组12只家兔),每个温度组动物每隔1 h取大腿股正中线处一块(0.4 cm×0.4 cm×0.2 cm)肌组织放入2.5%戊二醛液中固定,透射电镜下观察,确定不可逆变性的时限.结果:不同温度组即35℃、30℃、25℃、20℃、18℃、15℃、12℃、9℃、6℃和4℃组缺血家免电镜下骨骼肌细胞出现不可逆变性时间分别为3、4、5、6、7、9、12、16、28和50 h.结论:家兔骨骼肌不可逆变性的温度与时限成幂函数关系:T时限≈100/(X-X ).  相似文献

Objective To summarize the result of several kinds of flaps treated to first web space contraction. Methods Thirty-two cases of sever contracture of the first web space were treated between September 2000 and March 2009. Ultrathin groin flap, blood vessel pedicle reverse-flow island flap, neurocutaneous flap of the forearm, and free skin flap were used. The area of flaps were 3.0 cm × 5.0 cm-4.5 cm× 8.0 cm.The therapeutic result was observed by 3-12 months follow-up. Results There were partial necrosis at the distal part of flap in 1 case of nerve nutritional vascular pedicle skin flap and 1 case of ultrathin groin flap.The raw surface was healed by free skin grafting. The other flaps were all survived. There was some contraction observed in some patients after the K-wire released. The width of the first web space was augmented to an average of 50 mm (35-60 mm) and account to 80% to the uninjured side. The angle of the first web space was increased to an average of 70°(45°-80°). The contracture was improved significantly. The abduction and opposition function of thumb were restored. There was some degree decrease of grasp strength. The patients can fulfil daily life and partial work. But sensation was not good in some patients. The contour of the flaps:the contour of ultrathin groin flap was good. The contour of flaps in 3 cases of island skin flaps, 1 case of nerve nutritional vascular pedicle skin flap and 2 cases of free flaps were trimmed again in order to be improved. Conclusion The sever contracture of the first web space could be treated by different kinds of flaps, the suitable management should be chosen according to the specific situation.  相似文献
