Results The frequencies of micronucleated binucleated cell in 30 nmol/L FA were significantly higher than those in 60, 120, 240, 2 260 nmol/L FA (P.001～0.05), but no significant differences were observed either between those in 60 and 120 nmol/L FA, or between those in 120, 240 and 2 260 nmol/L FA within either groups when the genotype was the same.

结果 MTHFR C677T三种基因型的乳腺癌个体与对照组淋巴细胞在叶酸浓度为30 nmol/L时双核细胞微核率均显著高于60、120、240和2 260 nmol/L测试组（P.001～0.05），60 和120 nmol/L 两个测试组之间以及120、240和2 260 nmol/L三个测试组之间都未发现显著性差异。

The frequencies of CCR5delta32,CCR2b-64I,SDF1-3′A alleles in Dai population were 0.0000,0.2130,0.2030,respectively;The frequencies of CCR5delta32,CCR2b-64I,SDF1-3′A alleles in Chingpaw population were 0.000,0.1637,0.1770,respectively.Distributions of the CCR2b-64I,SDF1-3′A alleles among the both populations were in accordance with Hardy-Weinberg equilibrium.No statistical difference was found in the allelic frequencies of both CCR2b-64I and SDF1-3′A between male and female individuals.

结果表明，中国傣族景颇族人群中未发现CCR5△32等位基因突变；傣族CCR2b-64I、SDF1-3′A基因突变频率分别为0.2130和0.2030，景颇族CCR2b-64I和SDF1-3′A基因突变频率分别为0.1637和0.1770；与中国汉族人群相比较，傣族和景颇族中SDF1-3′A突变频率较低（P值分别为0.0322和0.0021）；两个民族的CCR2b-64I和SDF1-3′A等位基因群体分布符合Hardy-Weinberg平衡，在性别之间分布无显著差异。

In the second operation, the cases receiving choleeystostomy had less peritoneal adhesion, anatomic structure changes, haemorrhage[(30-50) mL vs (100-200) mL] and operation time[(2.5-3.0) h vs (3.5-5.0) h] than those receiving choledochotomy with T-tube drainage ,and did not appear inadequate drainage for cystic duet obstruction.

而Ⅰ期行胆囊造瘘术的患儿，未发现有因胆囊管梗阻而致胆汁引流不畅者，且Ⅱ期手术时胆总管周围结构较清晰，手术操作相对容易、出血少(30~50mL)、耗时短(2.5~3.0h)。
