In women who have undergone menopause, the function of thyroid hormone in their body begins to decline and thus affects the ability of the body to produce energy. The purpose of this study was to determine the correlation between the intakes of carbohydrates, proteins, and fats and random blood sugar levels in menopausal women.Methods: This study was a correlational analytical research with a cross-sectional design, which was conducted in 72 menopausal women recruited by the purposive sampling technique. In this study, a 24-hour food recall form was used, and randomized blood sugar levels were measured using a glucometer. The analysis of the data was performed using a Pearson product moment and multiple linear regression.Results: Carbohydrates and fats together affected random blood sugar levels with an F-value of 25.810 and a p-value of 0.000.Meanwhile, adjusted R^2 showed the value of 0.411, indicating that the difference in the intake of carbohydrates and fats together affected random blood sugar levels by 41.1%.Conclusions: Intake of carbohydrates and fats affected random blood sugar levels, whereas the rest were influenced by other factors,and protein intake was unrelated to random blood sugar levels in menopausal women.展开更多

The high blood fat model was established by feeding mouse on high fat feedstuff. Compared with control group, the concentration of HDL-C, the ratio of HDL-C/TC increased;while the concentration of TC, LDL-C and TG decreased in experimental groups. Conclusion: FGS was an effective serum lipid regulator and can be developed as medicine and health food.展开更多

The experiment shows that the absorption spectra of blood are of serious noise in the wave band of 200 to 300 nm, which hides the useful spectral characteristics. The effective separation of the noise was achieved by db4 wavelet transform, and the signals of reconstruction have been obviously improved in the noise serious wave band, reflecting some useful information. The absorption peaks of different samples are displaced to some degrees. The correlation between absorbance at 278nm and blood fat concentration is no significant and random. Based on the evident correlation between serum absorption spectrum and blood fat con-centration in the wave band of 265 to 282nm, a neural network model was built to forecast the blood fat concentration, bringing a relatively good prediction. This provides a new spectral test method of blood fat concentration.展开更多

Patients in control group were treated with basic feed for feeding, other groups of rats are used high fat diet were fed to establish hyperlipidemia rat model, in the process of modeling and prophylactically, determination of rats after 10 weeks of lipid metabolism and susceptibility of LDL to oxidation and blood viscosity concentration coagulation state.Result: Antioxidant capacity of the model group rat's serum LDL-C decreased significantly, and simvastatin group and three groups of lipid-lowering mixture group rats serum LDL antioxidant capacity were significantly enhanced;and high lipid mixture, LDL antioxidant ability in middle dose group rats were significantly higher than those of the Jiangzhi Decoction low dose group rats (P<0.05). Lipid mixture of high, middle dose group rats of EET and ETA P, ETA B (high, medium and low shear), IED, HCT, the role of the IEA was significantly higher in Jiangzhi Decoction low dose group rats (P<0.05 or P<0.05).Conclusion:Lipid-lowering mixture on experimental hyperlipidemia rats blood lipid metabolism and blood viscosity concentration coagulation state has a good regulatory role, and lipid-lowering mixture on blood lipid and blood flow abnormalities lipid-lowering mixture can also play a good regulation and therapeutic effect.展开更多

High salt and fat diets are known to have negative impacts on food intake (FI), body weight (BW), body composition (BC), glucose metabolism, and blood pressure. These factors have been studied as separate entities, but the main and interactive effects of dietary salt and fat received little study. The objective of this study was to examine the effect of sodium and fat content of the diet on FI, BW, and BC in male Wistar rats. Male Wistar Rats (n = 48) were allocated into 4 groups (n = 12) and received the following diets: 1. Normal sodium normal fat, 2. Normal sodium high fat, 3. High sodium normal fat, and 4. High sodium high-fat diet for 12 weeks. BW and FI were measured weekly. BC and organs’ weight were recorded post-termination. Regardless of sodium content, a greater FI was observed in normal-fat diet groups compared with high-fat diet groups. However, higher BW and fat (%) were observed in high-fat diet groups. Fasting blood glucose was higher in rats fed normal fat diets compared with those fed high-fat diets. Systolic and diastolic blood pressure was lower in rats fed either high fat, high salt, or normal fat, normal salt diet. In conclusion, fat but not salt content in the diet is a determining factor in the regulation of FI and body weight. Moreover, glucose metabolism can be influenced by both the fat and salt content of the diet.展开更多
