Objective To understand the current situation of iodine deficiency diserders(IDD) in Longyan City and to evaluate the effect of prevention and control measures of IDD in order to provide evidence for formulating prevention and control tactics. Methods During the year of 2006 and 2007, the 30 primary schools were screened by population proportion survey(PPS) from the 7 counties of Longyan City. Forty children aged 8-10 years in each school were randomly selected as a group to examine thyroid, and 7 children in each group were selected to measure the urine iodine and the salt iodine at the same time. The goiter rote, the median urinary iodine, the consumption rate of qualified iodized salt, the iodine salt coverage rate, the rate of qualified iodized salt and the non-iodized rate were detected. Results The goiter rate of children aged 8-10 years old in Longyan City was 0.94%(79/8438). The median urinary iodine was 259.12 μg/L. The consumption rate of qualified iodized salt was 97.86% (1462/1494). The iodine salt coverage rate was 99.46%(1486/1494). The rate of qualified iodized salt was 98.38 (1462/1486), and the non-iodized rate was 0.54% (8/1494). Conclusions All indicators have reached the national standard of eliminating IDD in Longyan City.

Objective To establish age related reference value for the new reticulocyte hemoglobin equivalent (RET-He) parameter in healthy children aged one to thirteen years. Methods Reticulocyte hemoglobin equivalent was measured by Sysmex XE-2100 after completing daily internal quality control in 424 healthy children and the outlying observations was handled afterward, Age related reference value anddistribution of RET-He level were described as the 2.5th and 97.5th centiles, and the equation regardingage related reference value was established through curve fitting methods. Results After grouping accordingto sex, the medians of boys and girls in RET-He were 31.30 pg,31.80 pg. Non-parametric test showed therewas no differences between the boys and girls. When the data from two group was integrated together, thefitted equations of RET-He were: P2.5 =-0.008X3+0.125X2 - 0.178X+26.456; P97.5= 0.021X2-0.184X+34.670(X refers to age) ; R2 were 0.85 and 0.90,respectively(P <0.05). There was statisticallysignificance for the above equations. Conclusions The reference value of RET-He in healthy children isdifferent from those in adult. The equations can be used to produce age related reference value. It could beuseful for anemia diagnosis, differential diagnosis and hematopoiesis screening at early stage.

To explore the relationship between serum thyroid stimulating hormone (TSH) level and obesity and nonalcoholic fatty liver disease (NAFLD) in euthyroid subjects, 1322 subjects were subjected to a questionnaire survey and physical examination. Fasting blood samples were collected to test serum TSH, plasma glucose and lipids. Fatty liver was diagnosed by type B ultrasonography. The relationship between serum TSH level and body mass index (BMI), percentage of body fat and NAFLD was analyzed. The results showed that serum TSH level was significantly higher in females than in males at the same group, and it was significantly higher in overweight group than in control group. Levels of body weight, BMI, waist circumference and percentage of body fat were increased in TSH >2.5 group compared to TSH ≤2.5 group in women. However, plasma lipids showed no significant differences. In males all the parameters showed no significant differences between two groups. Serum TSH was significantly correlated with body weight, BMI, waist circumference and percentage of body fat after adjustment for age in females. Multiple linear regression analysis revealed that percentage of body fat and BMI contributed significantly to the variance of TSH. Serum TSH level was significantly higher in nonalcoholic fatty liver group than in normal group in females. Multiple logistic regression analysis showed that TSH level was not the independent risk factor of NAFLD. Taken together the data suggest that serum TSH in normal range is significantly correlated with BMI and percentage of body fat in females. And the change of TSH level would not influence the prevalence of NAFLD.

OBJECTIVETo investigate the female sexual dysfunction (FSD) in type 2 diabetes patients, by comparing the sexual function between type 2 diabetic women and non-diabetic women with Female Sexual Function Index (FSFI).

METHODS115 type 2 diabetic women and 107 age-matched non-diabetes women were enrolled with similar backgrounds. Their sexual functions were evaluated with FSFI. Metabolic parameters such as body mass index, blood lipid profile, hemoglobin A1C, plasma glucose were also collected.

RESULTSTotal score of FSFI of the type 2 diabetic women were significantly lower than that of the non-diabetic controls (18.27±8.96 vs. 23.02±5.78, P=0.000). Scores of the FSFI domains (desire, arousal, lubrication, orgasm, satisfaction, pain) of the type 2 diabetic group were also lower than those of the control group. According to the FSD criterion (FSFI<25) available in China, the percentage of FSD in the type 2 diabetic group was significantly higher than that of the control group (79.2%vs. 55.0%, P<0.001). These trends seemed more prominent in pre-menopause subgroups. The logistic regression analysis indicated that age and diabetes were independent risk factors of FSD. Body Mass Index (BMI) also had influence in the diabetes group.

CONCLUSIONFindings from this study showed that there are more FDS in Chinese type 2 diabetic women than in their non-diabetic counterparts, especially in pre-menopause participants.

OBJECTIVETo investigate the effects of hypoxia on lipid metabolism in the normal human hepatic cell line L02 and to investigate the underlying molecular mechanisms.

METHODSL02 cells were exposed to hypoxic conditions (experimental groups: at 1% O2, 5% CO2, 94% N2 for 3, 6, 12, 24, or 48 hours) or normoxic conditions (control group: at 21% O2). Lipid droplet accumulation and triglyceride content were measured in each group by oil red O staining and biochemical assay, respectively. The mRNA expression levels of hypoxia-inducible factor (HIF)-2a and sterol regulatory element binding protein (SREBP)-1c were detected by reverse transcription-polymerase chain reaction. Protein expression levels of HIF-2a, adipose differentiation-related protein (ADRP), and Fas were tested by Western blot analysis.

RESULTSLipid droplet accumulation and the triglyceride content were significantly higher in the hypoxia group than the normoxia group. In addition, the hypoxia groups had significantly down-regulated mRNA expression of SREBP-1c (12h: 0.236+/-0.043, 24 h: 0.287+/-0.044, 48 h: 0.342+/-0.049 vs. normoxia: 0.503+/-0.037; F = 28.37, P less than 0.01) and FAS protein (12 h: 0.562+/-0.054, 24 h: 0.674+/-0.062, 48 h: 0.682+/-0.057 vs normoxia: 0.857+/-0.069; F = 16.08, P less than 0.01). In normoxic cells, little or no expression of HIF-2a protein was detected by Western blot. In hypoxic cells, HIF-2a protein expression peaked at 6h (0.973+/-0.067). ADRP protein expression was significantly higher in hypoxia groups than in the normoxia group (12 h: 0.319+/-0.043, 24 h: 0.732+/-0.056 and 48 h: 0.873+/-0.066 vs. 0.211+/-0.019; all, P less than 0.05.

CONCLUSIONExposure to hypoxic conditions might induce lipidosis in normal human hepatic cells by stimulating HIF-2a and ADRP expression.
