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 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 .

ObjectiveTo evaluate the probability of the fetal heart scanning in first trimester(11 -14+6 week) by transabdominal ultrasonography.MethodsBy using advanced ultrasound machine with high resolution transabdominal probe,249 fetal hearts were scanned.Four chamber view,left and right outflow view,three vessels view were obtained.The successful observation rates of these views under different gestational age were recorded.For 18 pregnant women with suboptimal transabdominal scanning condition,transvaginal scan were supplemented.ResultsAmong 249 singleton fetuses with low risk of congenital heart disease,four chamber view was successfully visualized in 227 (91.2％),left outflow view in 125(50.2％),right outflow view in 102(40.9％),three vessels view in 98(39.4％).The successful observation rate of these four views increased with gestational ages.The successful observation rate of each view in successive gestational age showed remarkable difference (P ＜ 0.05).The four chamber view had the highest successful observation rate with 95％ after 12 weeks.After 13 weeks,left and right outflow views visualizing rate was above 85％.Transvaginal scanning can increase the four chamber view successful observation rate.For observation of other views,transvaginal scanning,however,showed no superior than transabdomial scanning.ConclusionsHigh resolution transabdominal probe can be used to perform the fetal hearts scanning in early trimester.It will benefit to find the fetal heart malformation.
