Objective To understand the current situation of iodine deficient disorder(IDD) 10 years after achieving the stage goal of eliminating IDD in Longyan city and to evaluate the effect of prevention and treatment measures, and to provide the basis for the development of control strategies. Methods There were 7 counties in the city, and each county(city, district) was as a unit to carry out the inspection for organization and leadership,iodine salt management, monitoring and control, health education (referred to as the four management indicators)according to "The County-Level Assessment and Evaluation Implementation Detailed Rules of Realizing the Goal to Eliminate IDD in Fujian Province". According to the east, west, south, north and middle positions in each county,a village and a primary school were selected. Forty 8 to 10 year-old students in each school were randomly selected to check thyroid and among them 20 students were collected urine samples to determine urinary iodine. Nine townships were selected in the 7 counties of the city and among which 4 administrative villages were selected in each township. Eight edible salt samples from each household in each administrative village were collected to test salt iodine. Goiter was examined by palpation, the level of urinary iodine was examined by arsenic and cerium spectrophotometry, salt iodine was detected by direct titration. Results The average score of the four management indicators was 94.1 in Longyan city. The adjusted goiter rate of children aged 8 - 10 years old was 1.9%. The median of urinary iodine was 278.6 μg/L, among which less than 100 μg/L accounted for 4.57%(32/700), 100 -< 200 μg/L accounted for 24.00%(168/700), 200 - < 300 μg/L accounted for 25.29%(177/700), and higher than 300 μg/L accounted for 46.14%(323/700). The using rate of qualified iodized salt was 98.86%. The coverage rate of iodized salt was 99.50%, the qualified rate of iodized salt was 99.35%, and the rate of non-iodized salt was 0.50%. All the indicators had reached the national standard to eliminate IDD. Conclusions After achieving the stage goal of eliminating IDD, the disease is stable and the effect of control measures are significantly. But the iodine provided has a trend of more than suitable. Therefore, it is reasonable to reduce the current salt iodine content.

OBJECTIVETo investigate the sensitivity of gastric cancer stem cells (GCSCs) to 5-fluorouracil (5-FU), and to explore the cytological mechanism of drug-resistance of gastric cancer.
METHODSImmunohistochemical staining was employed to examine expression of stem cell marker CD44 and drug-resistance protein thymidylate synthase (TS) in 71 cases with gastric cancer. Based on morphology of cell colonies derived from AGS gastric cell line, colonies consisting of GCSCs were isolated, and expression of CD44 and TS, as well as self-renewal capacity of GCSCs were detected. Sensitivity of GCSCs to 5-FU was examined through CCK-8 assay.
RESULTSThe positive rates of CD44 and TS were 59.2% (42/71) and 56.3% (40/71) in gastric cancer, and expression of CD44 was associated with that of TS (χ(2)=12.76, P<0.01; Kappa=0.41). Serial sections indicated that CD44+ cancer cells simultaneously expressed TS. AGS developed morphologically diverse colonies, and the GCSCs colonies exhibited a tight and regular shape, which were called holoclone. Holoclones expressed CD44 and TS strongly, possessing capacity of robust self-renewal and forming a lot of second passage clones after incubation. Subclones expressed CD44 and TS weakly, forming less second passage clones. Paraclones almost did not express CD44 and TS, forming no second passage clone after incubation. Affected by 5-Fu, three holoclones showed less growth inhibition compared with another colony type and wild-type AGS cells. Furthermore, IC50 of 5-FU for three holoclones was (113.43±5.81), (272.68±25.75) and (118.14±17.75) μmol/L respectively, which were significantly higher than that of one subcolony type [(16.97±1.01) μmol/L] and AGS cells [(27.52±0.59) μmol/L] (all P<0.05).
CONCLUSIONSGCSCs possess lower sensitivity to 5-FU, and may play a critical role in drug-resistance of gastric cancer.

BACKGROUNDApoptosis is a major cause of ischemic heart dysfunction. Apelin, the endogenous ligand for the G-protein-coupled APJ receptor, has been reported to exert cardioprotective effects during myocardial injury. The aim of this study was to investigate the effects of apelin on apoptosis of rat cardiomyocytes induced by glucose deprivation (GD) and study the related signaling pathway.
METHODSApelin and APJ mRNA expression were determined by RT-PCR in neonatal rat cardiomyocytes during different durations of GD. Cardiomyocyte apoptosis was detected by annexin V-FITC/propidium iodide (PI) staining after GD for 12 hours with or without apelin-13 (10 and 100 nmol/L) pretreatment. Protein levels of Akt and the mammalian target of rapamycin (mTOR) as well as cell apoptosis were detected in the presence or absence of LY294002 (a phosphatidylinositol 3-kinases (PI3K) inhibitor) or rapamycin (a mTOR inhibitor).
RESULTSApelin mRNA expression was up-regulated when cardiomyocytes were exposed to GD for 6, 12, 18, and 24 hours compared with the base level (P > 0.05, P < 0.01, P < 0.01, P < 0.01). However, when cardiomyocytes were exposed to GD for up to 36 hours, apelin mRNA expression was 17% lower than the base level (P < 0.05). APJ mRNA expression paralleled that of apelin. Apelin-13 pretreatment at 100 nmol/L significantly inhibited GD-induced cardiomyocyte apoptosis (P < 0.05) and increased Akt and mTOR phosphorylation (P < 0.01, P < 0.01). At the same time apelin-13 (100 nmol/L) up-regulated Bcl-2 protein expression and down-regulated Bax and cleaved caspase-3 expression (P < 0.01, P < 0.05, P < 0.05). The anti-apoptotic effect of apelin-13 was blocked by LY294002 (P < 0.01) but not by rapamycin.
CONCLUSIONSThe endogenous apelin-APJ system is compensatorily up-regulated and ultimately down-regulated following sustained myocardial ischemia. Apelin protects against ischemic cardiomyocyte apoptosis via activation of the PI3K/Akt pathway.
