The ISSR fingerprinting of 18 Japanese plum cultivars and 12 plum species or variety were established by using optimum system with primer 5"-9T-3"and 5"-9C-3", respectively. The identification rate of plum cultivars and species or variety was 100%. The effects of five important components on reaction of SSR were studied with Prunus salicina cv. Meilili. The results showed that the optimum concentration of five important components i.e. Tag DNA polymerase, Mg +, single primer, template DNA and dNTPs in 25 μL reaction system of SSR were 1.5u, 2.0mM, 0.8 μ M, 30~40ng and 0.16~0.24mM, respectively. The dendrograms of these cultivars was contructed according the Jaccard coefficient of similarity.

利用该优化体系，以5′-_9T-3′为引物，构建了中国李18个品种的ISSR指纹图谱，该引物可将这些品种完全区别开来；以5′-_9C-3′为引物，构建了李属6类种质资源的ISSR指纹图谱，该引物区分率为100％。4、中国李品种适宜的SSR反应分析体系是：25μL SSR反应体系中，Taq DNA聚合酶、Mg~(2+)、每个引物、模板DNA和dNTPs等5种成分的适宜浓度分别是：1.5u、2.0mmol·L~(-1)、0.8μmol·L~(-1)、30～40ng和0.16～0.24mmol·L~(-1)。5、采用RAPD、ISSR和SSR等三种分子标记技术对中国李品种资源54份和2个欧洲李品种进行了遗传多样性分析，并以品种间的遗传相似系数构建了Jaccard聚类树状图。

Methods Polymerise chain reaction and restriction fragment length polymorphism were used to analyze the polymorphisms of MTHFR genes C6677T and A1298C in 56 patients of colorectal cancer and 143 age-and-sex-matched control subjects.

方法以聚合酶链反应和限制性片段长度多态方法，对56例直肠癌患者和143例正常人对照的MTHFR基因C677T和A1298C基因型进行检测分析其对直肠癌风险的相关性。结果在正常对照组中，MTHFRC677TCC、CT、TT基因型频率分别为62·90%、35·08%和2·12%，而在直肠癌病人中分别为58·93%、26·77%和14·26%。A1298C与A1298C基因型在病例和对照中的分布差异无显著性意义。
