Objective: To explore the different genotypes’ susceptibility to intervention of coarse grain food in dyslipdemia population. Method: 409 middle and old aged residents with blood lipoprotein abnormalities were randomized to 2 groups: the intervention group (230 subjects) and the control group (179 subjects). Everyone of the former group was given a steamed bread of coarse grain food per day and health education once every month; while the control group was only given health education. Intervention period was 6 months. The genotypes of LPL-Pvu Ⅱ of the intervention group were analyzed by PCR-RFLP (restriction fragment length polymorphism) technique. Results: All indices in intervention group except WHR were improved after intervention. BMI, WHR, SBP, DBP, serum TG were significantly lower than control group; while serum HDL-C was significantly higher than control group after intervention. Among all genotype groups, the P+/P+ group was more sensible for the change of serum TG and more significant in the effect of improving blood lipids than the P-/P- group; and the susceptibility of change for TC and HDL-C in serum was least in the P-/P- group. Conclusion: There are good intervention effects of coarse grain food in dyslipdemia population. The susceptibilities to improve blood lipids vary with different geno-types of LPL-Pvu Ⅱ , especially for change of serum TG ,and P+/P+ group was more sensible.

Objective To evaluate efficacy of healthy canteen based-nutritional health promotion so as to provide evidence for popularization and application.Methods A total of 429 college professors and administrative staffs with a healthy canteen were selected as the intervention group in 2012 in Changzhou,and another 947 counterparts without a healthy canteen were selected as the control group.Those of the intervention group was further assigned to the ≥2 times/week and＜2 times/week subgroups.Blood pressure,fatty liver,serum triglycerides,blood glucose,total cholesterol,uric acid,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol and body mass index(BMI)were tested before and after the intervention.Results After the intervention,the mean serum glucose[(5.06±0.62)mmol/L],uric acid[(310.57 ± 71.79)μmol/L],total cholesterol[(4.88 ± 0.86)mmol/L],triglycerides[(1.39 ± 0.67)mmol/L]and low-density lipoprotein cholesterol[(2.51 ±0.62)mmol/L]of the intervention group were significantly decreased(t values were 7.513,2.126,2.062,3.731 and 8.891,respectively; all P＜0.05),and mean high-density lipoprotein cholesterol[(1.43±0.34)mmol/L]were significantly increased(t=-2.309,P＜0.05).After the intervention,mean serum glucose and uric acid of the control group were significantly increased(t values were-3.491 and-7.703,respectively; both P＜0.05),although there was no statistically significant difference of mean serum triglycerides,total cholesterol,low-density lipoprotein cholesterol and high-density lipoprotein cholesterol in the control group before and after the intervention(all P＞0.05).The abnormality rates of serum glucose,uric acid,total cholesterol,triglycerides,low-density lipoprotein cholesterol and BMI as well as the incidence of hypertension of the intervention group were significantly decreased after the intervention(x2 values were 4.202,3.940,4.031,7.305,59.422,4.273 and 7.385,respectively; P＜0.05).In the control group,although the abnormality rate of serum uric acid and the incidence of fatty liver were significantly inclined after the intervention(x2 values were 23.740 and 7.408,respectively; both P＜0.05),there were no significant difference of abnormal serum triglycerides,glucose,total cholesterol,low-density lipoprotein cholesterol and BMI as well as the incidence of hypertension before and after the intervention(all P＞0.05).Mean serum triglycerides[(1.15 ±0.68)mmol/L]and low-density lipoprotein cholesterol[(2.4 1±0.60)mmol/L]in the ≥2 times/ week subgroup were significantly lower than those of the＜2 times/week subgroup(t values were-4.884 and-2.513,respectively; both P＜0.05),and mean high-density lipoprotein cholesterol[(1.46±0.33)mmo]/L]of the ≥2 times/week subgroup was significantly higher than that of the＜2 times/week subgroup(t=2.032,P＜0.05).The abnormality rates of serum total cholesterol,triglyceride and low-density lipoprotein cholesterol in the ≥ 2 times/week subgroup were significantly lower than those in the＜2 times/week subgroup(x2 values were 3.963,9.947 and 4.589,respectively; all P＜0.05).Conclusion Healthy canteen based-nutritional health promotion model may provide an effective method to prevent and control the development of noncommunicable chronic diseases.

Objective To study the effect of Chinese wild rice diet on lipid metabolism in rats. Method Forty four male SD rats were divided into 4 groups:control group, high lipid group, white rice-flour group and Chinese wild rice group. All groups were given different experimental diets for 8 w and body weights, serum TC, TG, HDL-C, high sensitive C-reactive protein (hs-CRP), TNF-? and IL-6 were measured. Results The hyperlipidemic rat model was successfully induced. When compared with high lipid group and white rice-flour diet group, serum TG and TC contents were significantly decreased, and HDL-C significantly increased in the Chinese wild rice group. Moreover, Chinese wild rice group had lower contents of serum hs-CRP and TNF-? than those in high lipid group and white rice-flour group, but no effect on serum IL-6. Conclusion Chinese wild rice could improve lipid metabolism and low-grade inflammation of hyperlipidemic rats induced by high lipid diet.

OBJECTIVETo evaluate the effects of compound whole grain-soybean on insulin resistance and serum adipocytokines levels in impared fasting glucose population.

METHODSAccording to inclusion and exclusion criteria, 163 cases of impared fasting glucose (IFG) Chinese Han population from the age of 40 to 75 years old, were screened from 12 community health centers of three main districts of Nanjing city by the multi-stage cluster and simple randomization method from March to September, 2008. The IFG subjects were randomly divided into the intervention group (87 individuals) and control group (76 individuals) by quasi-experimental design. The intervention group was provided with compound whole grain-soybean and health education, while only health education was provided for the control group. Body mass index (BMI), waist-to-hip ratio (WHR), lipid profiles, fasting blood glucose (FBG), fasting insulin (FINS) and homeostasis model assessment of insulin resistance (HOMA-IR), adipocytokines including leptin, lipocalin 2 (LCN-2) and adiponectin (ADP) levels were measured before and after the half a year intervention period. Chi square test was used to analyze the distribution differences. Two-sample t-test was used to compare the differences of the two groups before and after the half a year intervention period, and paired t-test was used to compare the differences between before and after intervention in the intervention group or control group. Wilcoxon rank sum test was used to compare the differences of all indexes between after and before dietary intervention.

RESULTSAfter dietary intervention for half a year on the IFG population, BMI ((24.87 ± 3.69) kg/m(2)), FBG((6.27 ± 0.24) mmol/L), FINS((7.14 ± 1.05) mU/L) , HOMA-IR (1.99 ± 0.31), leptin ((13.07 ± 2.22) µg /L), LCN-2 ((67.42 ± 18.20) µg/L) of intervention group were decreased significantly compared to the levels of BMI ((25.16 ± 4.07) kg/m(2)), FBG((6.40 ± 0.28) mmol/L), FINS ((7.32 ± 1.54) mU/L), HOMA-IR (2.08 ± 0.45), leptin ((13.43 ± 2.52) µg/L), LCN-2((74.87 ± 17.81) µg/L) before dietary intervention, t values were 4.48, 7.08, 2.05, 3.39, 3.28 and 6.36, respectively, and all P values were < 0.05, while ADP ((5.07 ± 1.51) mg/L) of intervention group after dietary intervention was increased significantly compared to the level of ADP ((4.92 ± 1.53) mg/L) before dietary intervention, t = -2.47 and P < 0.05. The medians (P25, P 75) of differences after and before dietary intervention in the intervention group were BMI (-0.25(-0.68, 0.02) kg/m(2)), FBG (-0.08 (-0.20, 0.00) mmol/L), FINS (-0.15(-0.32, 0.00) mU/L), HOMA-IR (-0.07(-0.12, -0.03)), leptin (-0.36(-0.77, 0.12) µg/L), LCN-2 (-5.85(-14.29, -0.71) µg/L) and ADP (0.15(-0.13, 0.36) mg/L), and the medians of differences of after and before dietary intervention in the control group were BMI (0.00(-0.23, 0.29) kg/m(2)), FBG (0.00(-0.03, 0.04) mmol/L), FINS (-0.01(-0.13, 0.04) mU/L), HOMA-IR (-0.01(-0.05, 0.02)), leptin (-0.07 (-0.57, 0.46) µg/L), LCN-2 (-0.85(-5.39, 1.63) µg/L) and ADP (0.02(-0.19, 0.13) mg/L). There were significantly statistical differences between them (Z values were -3.65, -4.88, -3.08, -5.23, -2.16, -4.43 and 3.05, all P values were <0.05).

CONCLUSIONDietary intervention of compound whole grain-soybean can improves glucose level, increase insulin sensitivity and ameliorate insulin resistance state of IFG population.
