According to the literature, the usability of the same ranges from 10 clays to 2! days. The aim was to determine the usefulness of such a maximum time preserved grafts. This study comprised 50 patients, of which, take parts of skin with the size of 3 cm × 5 cm. It started from the 11th day after the 5 preparation were divided, one of which is a part applied to a suitable surface for accepting the transplant, the second part of the extended conservation 10 more days （to be transplanted） and the third placed in formalin and sent to histopatological analysis. Then, a series of five preparations were made, in which each subsequent extended period of conservation by one day longer, ending their 20th day. Usability over 50% of grafts preserved in NaCl solutions up to 20 days, and then felt. It is possible that a transplant is used with 30 days of preservation, but this is the exception, not the usual state.展开更多
目的探讨年龄、总前列腺特异性抗原(total prostate specific antigen,tPSA)、游离前列腺特异性抗原(free prostate specific antigen,fPSA)和Gleason评分诊断前列腺癌(prostate cancer,PCa)全身骨转移的作用,同时比较MRI及核素骨扫描...目的探讨年龄、总前列腺特异性抗原(total prostate specific antigen,tPSA)、游离前列腺特异性抗原(free prostate specific antigen,fPSA)和Gleason评分诊断前列腺癌(prostate cancer,PCa)全身骨转移的作用,同时比较MRI及核素骨扫描对骨盆区域骨转移的诊断价值,为临床早期诊断骨转移提供有效参考。方法回顾性分析51例确诊PCa的患者资料,由骨转移病灶的临床标准诊断骨转移,并分析全身骨转移的相关因素,同时比较MRI与核素骨扫描诊断骨盆区域骨转移的价值。结果(1)51例PCa患者分骨转移组(24例)与非骨转移组(27例),骨转移组tPSA、fPSA和Gleason评分明显高于非骨转移组(P<0.05)。当tPSA、fPSA取界值68.59、6.42 ng/mL时,诊断骨转移的敏感度和特异度最佳(分别为75.00%、81.50%和83.30%、81.50%)。(2)分析骨盆区域分为骨转移组22例和非骨转移组29例,MRI、核素骨扫描及二者联合诊断骨转移的敏感性、特异性、准确度分别为86.36%、93.10%、90.20%(P<0.05)和90.91%、86.21%、88.24%(P<0.05)及94.45%、79.31%、86.27%(P<0.05)。结论(1)tPSA、fPSA和Gleason评分是诊断PCa全身骨转移的危险因素,数值升高对预测骨转移有很好的指示意义,特别是当tPSA、fPSA取界值68.59、6.42 ng/mL时诊断效能最佳;(2)对骨盆区域研究发现MRI诊断PCa骨转移的特异性最高,与核素骨扫描联合诊断时敏感性最高,表明两者的联合使用可实现优势互补,有助于PCa骨转移的早期诊断。展开更多
