基于代谢组学的琼玉膏延缓衰老作用评价及机制研究
[Abstract]:Qiongyu ointment is one of the famous anti-aging prescriptions circulated in ancient books. It has been highly praised by health-preserving families in the past dynasties. However, the modern research on the mechanism of Qiongyu ointment's anti-aging effect is still in its infancy, which limits its application and promotion. Characteristics of Chinese medicine, the combination of system theory and reductionism research methods.
Objective:
In this study, the serum and urine of aging model rats after intervention with Qiongyu ointment were detected by metabonomics, and compared with normal group, model group and control group, the changes of metabolites were observed, the metabolic pathway was found, and the mechanism of Qiongyu ointment in delaying aging was analyzed. To evaluate the effect of Qiongyu ointment on delaying senility and to explore the possible metabolomic mechanism of Qiongyu ointment on delaying senility, and to lay a foundation for further development and application of Qiongyu ointment.
Method:
Sixty SD rats, half male and half female, were randomly divided into five groups: blank control group, model group, Qiongyu ointment group, western medicine control group (vitamin E), Chinese medicine control group (Liuwei Dihuang pill), 12 rats in each group. Subcutaneous injection of D-galactose 2.5m1 6550 -1. was continuously administered with 60d, and morphological examination and behavioral test (Morris water maze) were used to detect whether the model was successful.
24 hours urine was collected with a metabolic cage after the last administration, and a drop of sodium azide with a mass-volume ratio of 1/100 (w/v) was added for reserve. Rats were anesthetized by intraperitoneal injection of 10% chloral hydrate at a dose of 3 ml Buffer, urine buffer and supernatant were centrifuged at low temperature and high speed and placed in NMR tube for metabolomics detection. TopSpin software (V3.0) was used to pretreat the spectrogram. SIMCA-P+ software (V11.0) was used to analyze the normalized data for multivariate pattern recognition, such as principal component analysis (PCA), partial least squares method-discriminant. Analysis (PLS-DA), orthogonal partial least multiplication-discriminant analysis, etc. The correlation of metabolites in individual groups was analyzed by MATLAB 7.0 software, and the metabolites were input into KEGG database to find the related metabolic pathways.
Result:
1. General situation and model validation: Before and after modeling, there was no significant difference in body weight between groups, P 0.05 was not statistically significant, and there was no difference in body weight between groups. There was no significant difference between the other groups (P 0.05). Compared with the model group, there was significant difference between the two groups from the 4th day (P 0.05).
2. Principal component analysis of NMR spectrogram: PCA analysis showed that the distribution of serum samples in each group was relatively clear, R2X = 80.6%, Q2 = 0.718, with significant difference, while urine samples in each group were dispersed, R2X = 59.8%, Q2 = 0.475, with little difference.
3. Evaluation of the anti-aging effect of Qiongyu ointment: Through PLS-DA analysis, three medication groups, namely Qiongyu ointment group, western medicine control group, Chinese medicine control group, were significantly different from the model group. Especially the western medicine control group and model group were most distinct (R2Y = 0.935, Q2 = 0.799); Qiongyu ointment group and model group were also distinct differences (R2Y = 0.931, Q2 = 0.826), and Western medicine control group. There was no significant difference between group and Qiong Yu ointment group (R2Y=0.755, Q2=0.002).
4. Differential metabolites screening: 46 kinds of hemorrhagic serum and 18 kinds of urine metabolites were identified, and the correlation coefficient | R | 0.576 was statistically significant. There are 33 different metabolites, such as amino acid, valine, lysine and so on. Qiongyu ointment can regulate the changes of 27 of them. Urine samples have 9 different metabolites, such as acetoacetic acid, hippurate, dimethylglycine, succinate and so on. Qiongyu ointment can regulate the changes of 3 different metabolites. Succinate, glutamic acid and other metabolites are closely related to aging.
5. Metabolic pathway analysis: Differential metabolites mainly involve glucose metabolism, amino acid metabolism, energy metabolism, nucleotide metabolism, coenzyme factor and vitamin metabolism, lipid metabolism and other metabolic pathways.
Conclusion:
1. The time for model group to find the platform was significantly longer than that of other groups, and the modeling was successful.
2. in this study, the anti-aging effect of Qiong Yu ointment is mainly manifested in serum, but has little effect on urine.
3. Evaluation of anti-aging effect of Qiongyu ointment: Qiongyu ointment can regulate the changes of metabolites in aging rats. Its efficacy is similar to that of vitamin E, which is better than that of Liuwei Dihuang pill.
4. Major metabolites related to the mechanism of Qiongyu Ointment in delaying senility are acetate, lactate, succinate, glutamate and so on.
5. The mechanism of Qiongyu ointment in delaying senility is related to many metabolic pathways, especially pyruvate metabolism in glucose metabolism, oxidative phosphorylation in energy metabolism and amino acid metabolism involving glutamate.
