Objective To detect the proliferation of neural stem cells (NSC) and analyze the effects of taurine on NSC proliferation in rats with fetal growth restriction (FGR).Methods For in vivo experiment,pregnant rats were randomly divided into three groups:control group (n=5),FGR group (n=7) and taurine group (n=6) [treated with taurine,300 mg/(kg · d)].Rats in the latter two groups were fed with 40％ of food intake in control group throughout pregnancy to establish the FGR model.Fatty acid binding protein-7 (FABP-7) expression in brains was detected by immunohistochemistry.For in vitro experiment,pregnant rats were divided into two groups including control group and FGR group.FGR modeling was established in the same way as above.On the 14.5 day of pregnancy,NSC were isolated and cultured for five days to form neurospheres with different concentrations of taurine (control,0,5,10,15,20,30,40 mmol/L).Immunofluorescence staining was used to detect the expression of NSC-specific marker FABP-7.CCK8 test was used to detect the cell proliferating index.Neurospheres were collected at the end of culture and disaggregated to get the total number of viable cells.One-way ANOVA,Kruskal-Wallis Test,SNK-test and Tamhane's test were used for statistical analysis.Results Compared with the control group (18 012±3 016),the number of FABP-7-positive cells in FGR model group (10 173±1 728) was decreased (P＜0.05),but increased in taurine group (19 518±3 201) (F=200.8,P＜0.05).Free-floating neurospheres could be formed in both control and FGR groups and the cells within neurospheres were mostly FABP-7-positive and were then considered as NSC.The proliferation indexes in control,FGR,FGR+5 mmol/L taurine,FGR+10 mmol/L taurine,FGR+15 mmol/L taurine,FGR+20 mmol/L taurine,FGR+30 mmol/L taurine,FGR+40 mmol/L taurine groups were 1,0.80±0.07,0.92±0.11,1.33±0.24,1.20±0.15,1.11 ±0.14,0.80±0.12 and 0.82±0.08,respectively.The proliferation indexes in FGR groups treated with 10,15 or 20 mmol/L of taurine were significantly higher than that of FGR group without taurine interference (P＜0.05).The total cell numbers in the eight groups were (24.5 ± 0.6)× 105,(20.23 ± 1.09)× 105,(22.80 ±0.86) × 105,(27.53± 1.22)× 10s,(25.30±1.05)× 105,(22.70±0.72)× 105,(21.80± 1.80)× 105 and (18.06 ± 0.90)× 105,respectively.Compared with the FGR group without taurine interference,those treated with 5,10,15 or 20 mmol/L of taurine showed higher total cell numbers (all P＜0.05 or ＜0.01),while that treated with 40 mmol/L oftaurine was lower.Conclusions The number and proliferation of NSC in FGR fetal rat brains is significantly decreased,however,these could be reversed by antenatal supplementation of taurine.The best effect is shown when l0 mmol/L of taurine is given.

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.

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.
