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.

In this article,the authors analyzed the current status of the therapeutic effect evaluation of TCM and proposed some measures to improve the current therapeutic effect evaluation of TCM,quantificated messages from TCM four diagnostic methods,explored biological parameter reflected essence of diseases,introduced quality of life scale and PRO,in the hope of establishing a comprehensive system of therapeutic effect evaluation reflecting the superiority and characteristics of theory of body and spirit.

The article searched ancient literature from pre-Qin to Qing Dynasty,researched the character meaning,implication of physique and spirit,and the historical evolvement process of view of physique-spirit unity(ghost theory-sporadic physique and spirit theory-systemic view of physique-spirit unity-view of physique-spirit unity combined with Chinese medicine)so that the view of physique and spirit can be applied to medical domain preferably,which will help the clinic diagnosis and treatment.

Objective To study the major risk factors for female thyroid tumor in Hohhot of Inner Mongolia and to provide a scientific basis for prevention and treatment of the disease.Methods A case control study was carried out,190 female patients who had suffered thyroid tumor and had been operated on in the Affiliated Hospital of Inner Mongoha Medical College and Inner Mongolia Hospital from March 2010 to September 2011 were selected.Meanwhile,190 female patients who were excluded from being suffering this disease were chosen as controls.A formal questionnaire was made,including the following contents:the general situation,the life style and behavior habit,women's physiological and reproductive situation,job and life factors,personal disease,and medicine and genetic factors.Then,trained investigators who had at least got the bachelor degree interviewed all the patients in the two groups and the doctors in the office of ultrasound and pathology made the check-up.All data made up a database;statistical description and analysis was done with software SPSS 17.0.Through Logistic regression analysis,the relationship between all factors and female thyroid tumor was analyzed in order to find major risk factors related to female thyroid tumor in Hohhot.Results The results of Logistic regression analysis showed that the delay of the first pregnancy,the higher Body Mass Index,too much preserved food and seafood in the diet,higher level of education,negative live event were apparently related to female thyroid tumor (OR =1.527,22.729,2.271,4.303,1.117,1.489,all P ＜ 0.05).Conclusions The female thyroid tumor in Hohhot is a result of comprehensive effect of multiple factors.This study found that the delay of the first pregnancy,the higher Body Mass Index,too much preserved food and seafood in the diet,higher level of education,and negative live event are apparently related to female thyroid tumor,and these factors may be major risk factors for thyroid tumor based on the current epidemiological study.

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.
