A total of 115 patients with acute chest pain under the suspicion of acute myocardial infarction (AMI) were selected.By the onset time of chest pain,they were divided into two periods of ＜3 h and 3 -6 h respectively. Heart-type fatty acid binding protein (H-FABP)and such traditional cardiac biochemical markers as cardiac troponin T (cTnT),creatine kinase isoenzyme (CK-MB) and myoglobin (MYO) were tested to compare the sensitivity and specificity in the early diagnosis of AMI.The sensitivity of H-FABP was significantly higher than those of cTnT,CK-MB and MYO (P =0.026,0.005,0.048 ) ; the specificity of H-FABP was lower than those of cTnT,CK-MB in the diagnosis of AMI ( P ＞ 0.05 ).The sensitivities of H-FABP were 81.6％ and 78.1％ in the ST-elevation myocardial infarction (STEMI) and nonST elevation myocardial infarction (NSTEMI) groups respectively ( P =0.095 ).Regardless of the onset of chest pain at ＜ 3 h or 3 -6 h,the combination of H-FABP and cTnT had a higher sensitivity than those of cTnT,CK-MB and MYO in the early diagnosis of AMI (P =0.005,0.028).In the early and rapid diagnosis of AMI patients,H-FABP has a high sensitivity and a poor specificity.And it has some reference value.

Objective To investigate the correlations of body mass index (BMI) with plasma apelin, waist-hip ratio (WHR), fasting plasma glucose (FPG), glycosylated hemoglobin (HbAlc), biochemical indicator, blood fat and ultrasonic cardiogram (UCG) figures in patients with congestive heart failure (CHF).Methods A total of 41 elderly CHF patients (20 males and 21 females, aged 66.0±12.3 years) were divided into 3 groups according to BMI: normal group (n= 16), overweight group (n=13) and obese group (n= 12).And they were also divided into 2 subgroups: grade Ⅲ heart function group (n=22) and grade Ⅳ heart function group (n= 19).Enzyme linked immunosorbent assay was used to detect the levels of plasma apelin, and BMI, WHR, C-reactive protein (CRP), FPG, creatine kinase (CK), CK-MB, blood fat, electrolyte and UCG of all patients were detected .Results There were significant differences in waist circumference, hip circumference and WHR among the 3 groups (P<0.05 or P<0.01).But there were no significant differences in high density lipoprotein (HDL), low density lipoprotein (LDL), total cholesterol (TC), triglyceride (TG), FPG, HbAlc, CK, CK-MB, potassium, sodium, CRP, left ventricular internal diameter at end-diastole (LVIDd), left ventricular internal diameter at end-diastole (LVIDs), interventricular septal thickness at end diastole (IVSd) and left ventrieular ejection fraction (LVEF) among the 3 groups (all P> 0.05).The apelin level was higher in obese group than in normal group and in overweight group ((0.48±0.15) mg/L vs.(0.18±0.15) mg/L and (0.27±0.06) mg/L, both P<0.01].And the plasma apelin level was higher in grade Ⅳ heart function group than in grade Ⅲ heart function group [(0.35±0.16) mg/L vs.(0.26±0.13)mg/L, P<0.05].The level of plasma apelin was positively correlated with BMI, white blood cell, CK, hemoglobin and TG, and was negatively correlated with cardiac function and LVEF.The influencing factors for the plasma apelin were BMI (β=0.672, P<0.01), age (β=0.244, P<0.05) and HDL (β=-1.000, P<0.01).Conclusions The plasma apelin level is closely correlated with the development of heart failure.Cardiac dysfunction is more severer when the level of plasma apelin is higher.The high level of plasma apelin may be one of factors for the higher survival rate of the obese CHF patients.Plasma apelin level may be used as an indicator of state of illness.

Objective To analyze the coverage of iodized salt and the focus population iodine nutrition after implementing new standard of iodized salt in Hainan Province.Methods Eighteen cities (counties,districts) were divided into eastern coastal,western coastal and inland areas according to coastline and terrain of Hainan Province in 2013.One township (town,street) was sampled from each city (county,district) in the east,the west,the south,the north and the center of these areas.Four villages (committees) and 15 households in each village (committee),and 40 children aged 8-10 in one primary school,20 pregnant women and lactating women were sampled from each township (town,street).Iodized salt samples collected from household were monitored by the method of direct titration;random urine samples of children aged 8-10,pregnant woman and lactating woman were tested by arsenic cerium catalytic spectrophotometry.Results Totally 6 310 edible salt samples were tested,and the median of salt iodine was 25.9 mg/kg.The coverage of iodized salt was 97.92％ (6 179/6 310).Residents consumption rate of qualified iodized salt reached 95.47％ (6 024/6 310),and the rate of non-iodized salt was 2.08％ (131/6 310).About 4 444 urine samples of children aged 8-10 were examined,and the median of urinary iodine was 165.4 μg/L,in which suitable urinary iodine (100-199 μg/L) accounted 49.3％ (2 194/4 444);about 1 286 urine samples of lactating woman were examined,the median of urinary iodine was 122.3 μg/L,≥ 100 μg/L was 60.6％ (779/1 286);about 813 urine samples of pregnant woman were examined,the median of urinary iodine was 126.6 μg/L,59.6％ (485/ 813) of this group were urinary iodine deficiency (＜ 150 μg/L).There were significant differences between the three groups in the east,the middle and the west areas of Hainan Province (children:176.7,147.7,158.0 μg/L,lactating women:148.7,108.7,106.7 μg/L,pregnant women:146.7,108.0,147.1 μg/L,H =34.70,26.76,35.95,all P ＜ 0.01).Conclusion The results have showed that pregnant woman are iodine deficiency,they should be given more iodine.
