The lymphatic vessel is one of the earliest routes for systemic neoplastic metastasis. But reports on research of the lymphatic vessel have been few compared to the study for tumor vessels. In the past few years,along with advances in understanding about the construction features of the lymphatic system,work has been done to determine the anatomic fundamentals of lymphatic metastasis. Many new specifi c markers of the lymphatic endothelium had been reported, which is useful to differentiate lymphatic vessels from capillary vessels. The lymphatic vessels are usually found in the animal tumor models, human tumors and peritumoral tissues. Furthermore, the molecular mechanism of lymph-angiogenesis has been discovered, which provide effective targets for anti-lymphatic metastasis of malignant tumors, make optimization of individualized treatment strategy possible to restrain lymph-angiogenesis of malignant tumors and so it could benefi t in improving patients' prognosis and survival.

Objective To explore the Csx/Nkx 2.5 gene expression in the heart during the embryonic period and its mutation in subjects with congenital heart disease(CHD). Methods Immunohistochemistry was used to reveal the Csx/Nkx 2.5 gene expression, and PCR-SSCP-silver staining and DNA sequencing for mutation. Sixty-three embryos or fetus, 126 children with congenital heart diseases and 30 normal controls were included in the study. Results Elevated expression of Csx/Nkx 2.5 gene was found in atrium and trabecular of ventricle. After 16 weeks of gestation, the expression in atrium was stable, while slightly reduced in the trabecular. The expression in the ventricle was lower than that in the atrium in early embryonic stage followed by continuous increase which was most remarkable in 13~16 weeks and kept stable after 16 weeks. No expression of Csx/Nkx 2.5 was detected in epicardium. Three different kinds of gene polymorphisms in the third base of the 21st amino acid codon were found in all subjects:A,G,A/G. Conclusions Gene Csx/Nkx 2.5 plays an important role during the fetal heart development and its expression varies in different parts of the heart during different period in fetal development. Neither the sporadic nor the CHD cases showed any mutations in this study.

Objective:To explore role of sodium/chloride transporter member 3 (SLC12A3 ) gene haplotype mutation on Mongolians with essential hypertension (EH) .Methods:A total of 170 EH Mongolians (EH group) and 220 normotensive Mongolians (normotensive group) specimens were collected from Xilin Gol league .Mononucleotide sites (tagSNP) were se-lected using Haploview software ,genotypes were divided using real-time polymerase chain reaction (PCR) and SHESIS on-line analysis software was used to establish haplotype .Results:(1) Body mass index (BMI) ,blood lipids (except high den-sity lipoprotein cholesterol ) and blood pressure of EH group were significantly higher than those of normotensive group , P<0.01;(2) A total of nine tagSNPs were screened from frequent polymorphic mononucleotides (SNPs) of SLC12A3 gene ,and there existed strong linkage disequilibrium (D′> 0.8) in three polymorphic sites (rs2289009 ,rs13306673 and rs7204044 ) .These three polymorphic sites constituted four frequent haplotypes with frequency >3% in total ,and frequen-cy of haplotype GCA in EH group was significantly lower than that of normotensive group (9.4% vs .16.6% ) ,OR=0.52 ,95% CI 0.33~0.84. Conclusion:There is relationship between GCA haplotype of SLC12A3 and hypertension in Mongolians ,individuals with GCA haplotype have a lower risk of hypertension .
