ABSTRACT
Objective To investigate the correlation and significance of S100A12 with obstructive sleep apnea hypopnea syndrome (OSAHS).Methods Fifty-three patients with OSAHS were chosen as OSAHS group and 46 healthy volunteers were chosen as control group.The levels of S100A12 and hs-CRP in the two groups were compared,and its relationship with those of epworth (ESS),apnea hypopnea index (AHI),and minimum blood oxygen saturation (L-SpO2) were analysised.Results The scores of ESS,BMI,A HI,L-SpO2,hs-CRP and S100A12 in two groups were statistically significant (P＜0.05).The severity of hs-CRP in severe OSAHS group was significantly higher than that of mild OSAHS group (P＜0.05).There was no significant difference in hs-CRP between moderate OSAHS group and mild OSAHS group and severe group (P＞0.05).The level of S100A12 in severe OSAHS group was significantly higher than that of moderate OSAHS group and OSAHS mild group(P＜0.05).The level of S100A12 in moderate moderate group was significantly higher than that of mild group(P＜0.01).hs-CRP was negatively correlated with ESS and AHI (r=0.822,0.787,P＜0.01),was positively correlated with L-SpO2 (r=-0.740,P＜0.01),S100A12 was positively correlated with ESS and AHI (r =0.707,P ＜ 0.01),and negatively correlated with ESS and AHI (r =0.707,0.807,P＜0.01),and negatively correlated with with L-SpO2 (r=-0.670,P＜0.01).Conclusion S100A12 is associated with OSAHS.The higher the severity of OSAHS,the higher the S100A12 value,which can be used as a new predictor of cardiovascular disease risk in OSAHS patients.
ABSTRACT
Objective To investigate the effects of different doses of rosuvastatin on expression of liver X receptor(LXR) and caveolin-1 in cultured human monocyte-macrophage cells which induced by oxidized low density lipoprotein (ox-LDL).Methods The human monocyte-macrophage cells were divided into six groups:control group,ox-LDL group,different doses of rosuvastatin group (0.01 μmol/L,0.1 μmol/L,1 μmol/L,5 μmol/L).The expression of LXR mRNA and caveolin-1 mRNA were assayed by RT-PCR.Results LXR mRNA expression induced by ox-LDL in the control group and ox-LDL group were 1.00 ± 0.02,0.26 ± 0.02,and the difference was significant (t =56.39,P ＜ 0.001).Meanwhile,caveolin-1 mRNA expression in ox-LDL is (0.27 ± 0.01) fold than that in control (t =31.27,P ＜ 0.001).Meanwhile,There were significant differences among ox-LDL group and the different doses of rosuvastatin group in terms of LXR mRNA and caveolin-1 mRNA expressions (F =72.154,66.007,P ＜ 0.001).Along with the increase the doses of rosuvastatin,there was an increased trends of LXR mRNA and caveolin-1 mRNA expressions (P ＜ 0.05).Conclusion Rosuvastatin and upregulated the LXR mRNA and caveolin-1 mRNA expressions in a dose dependent manner.
ABSTRACT
Three kinds of fortified biscuits and bread were given as breakfast for 5 months to 106 preschool children 4-6 years old lodged in a kindergarten, with a control group taking common biscuits and bread without fortification. 6 g protein and 160 kcal were supplied by 50 g of fortifed foods in which 0.25 g lysine, 0.25 g lysine and 0.8 mg riboflavin, and cod liver oil and calcium in addition to lysine and riboflavin were fortified respectively. The results showed that a diet with intake of 2.1 g protein and 71 kcal/kg body weight fortified on the average by 228 mg lysine or 228 mg lysine and 1.1 mg riboflavin increased the monthly increment of body weights, heights, and urinary excretions of creatinine per day. There was also a tendency of improvement, in nitrogen retention. The urinary excretion of riboflavin in load test was increased in the group taking the second kind of fortified foods.
