BACKGROUND:Thyroid cancer stem cells are one of the reasons for tumor resistance that promotes tumor development. The research of thyroid cancer stem cells has provides a new clinic means for the diagnosis and treatment of thyroid cancer. OBJECTIVE:To overview the discovery, identification, and correlation of thyroid cancer stem cells with thyroid cancer. METHODS:A computer-based online search of PubMed database and Wan Fang database between 1995-01/2014-01 was performed to search related articles with the key words of“thyroid cancer, cancer stem cell, stem cell, cancer suppressor gene”in English and Chinese, respectively. Literatures related to thyroid cancer stem cells were selected;in the same field, the articles published lately in authoritative journals were preferred. RESULTS AND CONCLUSION:A total of 561 literatures were primarily selected, and 57 documents were involved for result analysis according to inclusion criteria. Cancer stem cells have become a focus in the study of carcinogenesis. Stem cells also exist in the thyroid gland and its tumor. At present, there are several ways to isolate and identify thyroid cancer stem cells. The tumor thyroid stem cells are closely related to the occurrence, transfer and treatment of tumors. But whether we can cure thyroid cancer through restraining or eliminating thyroid cancer stem cells is stil unknown that needs further studies.

OBJECTIVETo assess the association of single nucleotide polymorphisms (SNPs) of leptin receptor (LEPR) gene with essential hypertension (EH) and body mass index (BMI) among ethnic Mongolian and Han Chinese from Inner Mongolia region.

METHODSIn total 411 Han Chinese patients with EH and 480 healthy controls, together with 658 Mongolian patients with EH and 403 healthy controls, were collected. The SNPs of the LEPR gene were determined with ligase detection reaction (LDR). Logistic regression was used to analyze the association of the polymorphisms of each locus with EH and BMI. MDR software was used to analyze the interaction between above loci and environmental factors.

RESULTSGenotypic frequencies of LEPR gene rs7555955, rs1137100 and rs1137101 loci had differed significantly among ethnic Hans with EH and the control group (All P<0.05). While those of rs7555955, rs1805094, rs1137100, rs11579567, rs1805134 and rs6669354 loci had differed significantly among ethnic Mongolians with EH and the control group (All P<0.05). After adjustment for confounders, logistic regression analysis indicated that age (OR=2.97, 95%CI:1.94-3.99), BMI (OR=3.93, 95%CI:2.91-5.96), and rs1137101 (AA) (OR=3.96, 95%CI:1.32-11.90) were independent risk factors for EH among ethnic Hans, while age (OR=2.99, 95%CI:2.98-4.57), BMI (OR=3.03, 95%CI:1.05-1.27), rs7555955 (AG, AA) (OR=12.12, 95%CI:2.80-52.43; OR=6.35, 95%CI:1.44-27.94), and rs7555955 (GG) were independent risk factors for EH among ethnic Mongolians (P<0.05).

CONCLUSIONAge and BMI are independent risk factors for EH in both ethnic Han and Mongolian Chinese. rs1137101 locus is associated with EH among ethnic Hans, while rs7555955 locus is associated with EH among ethnic Mongolians.
