Impact of composition upon the cold flow properties for biodiesel was investigated with gas chromatography-mass and cold filter plugging point tester based on the theories of molecular structure and crystal growth.

上颌牵引成骨技术矫治腭裂继发重度上颌后缩畸形术后颌骨稳定性明显提高，3例患者术后A点前后向复发率仅为8％，垂直方向复发率为14％。

All the LOH on 〓 and 〓 was observed in invasive ductal carcino- ma, carcinoma simplex, medulary carcinoma and scirrhous carcino- ma, no deletions at these sites were observed in any invasive lobular carcinoma and others. These results imply an etiological difference.P53 gene is a hot point gene in the occurrence and development of breast, cancer. PCR-SSCP analysis was performed to detect P53 gene point mutation in the region between exon 5 and 8, 5 of 12 (41. 6%) stage I breast cancer patients contain mutation of P53, 3 of 5 patients were accompanied by 〓 deletion. These results suggested that point mutation and allelic loss of P53 gene are two vi- tal genetic events in earlier stage of breast tumorigenesis.

我们还发现，〓和〓位点LOH均分布在乳腺浸润性导管癌、单纯癌、髓样癌及硬癌中，在浸润性小叶癌和某些特殊类型乳腺癌中全部为LOH阴性，上述位点LOH可能与某些组织学类型乳腺癌的发生有关。P53基因是乳腺癌形成过程中的一个热点基因，本研究对12例Ⅰ期乳腺癌组织标本中P53基因热点区域第5、6、7、8外显子点突变进行了测定，发现41.6％（5／12）的病人有P53基因一个或多个点突变，其中3例同时伴有〓位点LOH，表明P53基因点突变和等位基因缺失是发生在乳腺癌形成早期的一个重要遗传学事件。
