ABSTRACT

ObjectiveTo observe the effect of polysaccharides from root, stem, leaf and fruit of Schisandra chinensis on exercise endurance in the aging mice induced by D-galactose. MethodMale ICR mice were randomly assigned into six groups: blank control group, model group, root polysaccharide group, stem polysaccharide group, leaf polysaccharide group and fruit polysaccharide group. The mice were administrated with distilled water or root, stem, leaf and fruit polysaccharide (total sugar content of 35 mg·kg-1) by gavage. Thirty minutes after the administration, the blank control group was subcutaneously injected with normal saline, and the other groups with D-galactose (300 mg·kg-1), once daily for 6 weeks. The anti-fatigue effects were evaluated by rotarod test, forelimb grip strength test, and weight-loaded swimming test. The fatigue and oxidation indicators such as blood urea nitrogen (BUN), serum lactic acid (LD), lactic dehydrogenase (LDH), creatine kinase (CK), superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), and reactive oxygen species (ROS) were measured by chemical colorimetry. The protein levels of pro-apoptotic protein B cell lymphoma-2 (Bcl-2)-associated X protein (Bax), anti-apoptotic Bcl-2 and cleaved cysteinyl aspartate-specific protease-3 (cleaved Caspase-3) in mouse skeletal muscle were detected by Western blot. ResultIn the rotarod test, the time on rod was shorter in the model group than in the blank control group (P<0.01) and the root, stem and fruit polysaccharide groups (P<0.01). In the forelimb grip strength test, the forelimb grip strength in the model group was lower than that in the blank control group (P<0.01) and the root, stem, leaf and fruit polysaccharide groups (P<0.01). In the weight-loaded swimming test, the weight-loaded swimming time in the model group was shorter than that in the blank control group (P<0.01) and the root, stem, leaf and fruit polysaccharide groups (P<0.01). Compared with those in the blank control group, the BUN, LD, LDH and CK levels significantly increased in the model group (P<0.05, P<0.01). The increases in BUN and LDH levels were decreased by the root, stem and fruit polysaccharides (P<0.05, P<0.01) and those in LD and CK by the root, stem, leaf and fruit polysaccharides (P<0.05, P<0.01). Compared with the blank control group, the model group showed decreased SOD and GSH-Px activities (P<0.01) and increased MDA and ROS content (P<0.01). Compared with the model group, the root, stem, and fruit polysaccharide increased the SOD activity (P<0.05, P<0.01) and decreased ROS content (P<0.01). The root and stem polysaccharides decreased the MDA content (P<0.01) and increased the GSH-Px activity (P<0.05, P<0.01). Compared with the blank control group, the model group showed up-regulated protein levels of Bax and cleaved Caspase-3 and down-regulated protein level of Bcl-2 (P<0.01). Compared with the model group, the root, and stem polysaccharides down-regulated the protein levels of cleaved Caspase-3 (P<0.05) and up-regulated protein level of Bcl-2 (P<0.01). ConclusionThe polysaccharides from the root, stem, leaf, and fruit of S. chinensis have anti-fatigue effect in D-galactose-induced aging mice. The polysaccharides may exert such effect by improving the antioxidant capacity and inhibiting the apoptosis of skeletal muscle cells.

ABSTRACT

Fatigue is a widespread and complex physiological phenomenon. Chronic fatigue can lead to cardiovascular dysfunction, mental disorders and other serious pathological reactions. Therefore, how to relieve fatigue accurately and effectively is an important proposition to implement the concept of "Healthy China" in the new era. As an important part of Chinese medicine health industry, Chinese medicine health food has been developing rapidly in recent years. At present, there are 1 157 kinds of anti-fatigue health food on the market in China, most of which are single Chinese medicine and its compound. However, their functions are generally labeled as "anti-fatigue", and their function positioning is too extensive and unclear. With the deepened understanding of fatigue classification and its physiological and pathological basis, it is urgent to be combined with the progress of modern chemical and pharmacological stu-dies to differentiate and precisely position the anti-fatigue health effects of traditional Chinese medicine. For this purpose, the classifications of fatigue were summarized in this paper, and the mechanism of fatigue was explained from the aspects of energy metabolism, accumulation of metabolites, oxidative stress, inflammation, hypothalamus pituitary adrenal axis and so on. We selected 10 traditional Chinese medicines which are most frequently used in health food, analyzed their anti-fatigue effect mechanisms, and summarized the best types of anti-fatigue food, so as to promote the scientific development of anti-fatigue health food industry, expand the market application scope of anti-fatigue health food, better respond to the construction of a healthy China and serve for people's health.

ABSTRACT

Objective: To explain the phenomenon that Panax ginseng is not compatible with Raphani Semen based on pharmacodynamics and pharmacokinetics. Methods: The forced swimming time and biochemical parameters such as blood lactate (BLA), serum urea nitrogen (SUN), and hepatic glycogen (GLU) were determined for anti-fatigue experiment. The UPLC-MS/MS was used to analyze the pharmacokinetics of Rg1, Re, Rb1, and Rd after orally administration of P. ginseng and P. ginseng combined with Raphani Semen to rats. Pharmacokinetic differences of four ginsenosides between single uses of P. ginseng and combined with Raphani Semen were investigated. Results: The results showed that Raphani Semen tended to significantly reduce the anti-fatigue activity of P. ginseng. Co-administration of P. ginseng and Raphani Semen had significant effects on the pharmacokinetics of the four ginsenosides in rats compared to that observed with P. ginseng extract alone. The AUC0–12 h values of the four ginsenosides in PG group were higher than the corresponding values in the PR group. It can be inferred that Raphani Semen decreased the blood exposure of the four ginsenosides in rats when it combined with P. ginseng. Conclusion: The anti-fatigue activity and pharmacokinetic results showed that Raphani Semen may reduce the pharmacological actions of P. ginseng.

ABSTRACT

Aim: To study the anti-fatigue,anti-oxidative and hemostatic effects of small molecule Asini Corii Colla (SMACC). Methods: Rat model of complex blood deficiency was established to detect the exhausted time of swimming, hematology, superoxide dismutase (SOD), serum maleic dialdehyde (MDA), and lipid peroxide (LPO) levels, aiming to explore the anti-fatigue and anti-oxidative effects of SMACC. ICR mice were used to measure the blood clotting time (CT) and bleeding time (BT). Fevered and bleeding model and the heparinized bleeding model in rats were established to investigate the effect of SMACC in hemostasis and its possible mechanism. Results: Compared with model group, SMACC significantly prolonged the swimming time of model rats (P < 0. 05, P < 0. 01) and decreased the content of serum MDA, LPO (P < 0.05,P<0.01) at doses of 1. 500,0. 750,0. 375 g. kg-1,and increased the number of lymphocytes in the blood at doses of 1. 500,0. 375 g. kg-1 (P <0. 05). SMACC of 3. 00,1.50 g kg-1 significantly reduced the BT and CT (P < 0. 05). SMACC markedly reversed the prolonged prothrombin time (P < 0. 05) and the adverse changes of the hematological indicators. Conclusions: SMACC has the pharmacological effects of anti-fatigue, anti-oxidation and enhancing endurance, and also the effects of hemostasis and convergence.

ABSTRACT

Objective: To explore the anti-fatigue mechanism of Astragali Radix based on network pharmacology. Methods: The main active ingredients of Astragali Radix were obtained by TCMSP and the results of our previous work. GeneCards and OMIM were used to predict and screen the therapeutic targets of Astragali Radix. The Cytoscape 3.6.0 software was used to construct the active components-targets network of Astragali Radix. The protein interactions network was constructed using the String database and Cytoscape software. The GO and KEGG pathways involved in the targets were analyzed by using DAVID database. Results: The results showed that 11 active components including six flavonoids (calycosin-7-O-β-D-glucoside, calycosin, ononin, formononetin,7,2’-dihydroxy-3,4-dimethoxyisoflavan, 3-hydroxy-9,10-dimethoxypterocarpan), four saponins (astragaloside I, II, III, IV) and sucrose and 76 targets of Astragali Radix were involved. The network analysis results showed that the process of nitric oxide biosynthesis, hydrogen peroxide reaction, positive regulation on brown adipocyte differentiation, and active oxygen metabolism were mainly involved by adjusting the cancer, FoxO, PI3K-Akt, HIF-1, VEGF, MAPK and other signaling pathways to exert its antifatigue effect. Conclusion: This study reflects the characteristics of multi-components, multi-targets, and multi-pathways of Astragali Radix, which provides new ideas and clues for further research on the mechanism of anti-fatigue effects of Astragali Radix.

ABSTRACT

BACKGROUND: Performing cognitive tasks and muscular fatigue have been shown to increase muscle activity of the lower extremity during quiet standing. A common intervention to reduce muscular fatigue is to provide a softer shoe-surface interface. However, little is known regarding how muscle activity is affected by softer shoe-surface interfaces during static standing. The purpose of this study was to assess lower extremity muscular activity during erect standing on three different standing surfaces, before and after an acute workload and during cognitive tasks. METHODS: Surface electromyography was collected on ankle dorsiflexors and plantarflexors, and knee flexors and extensors of fifteen male participants. Dependent electromyography variables of mean, peak, root mean square, and cocontraction index were calculated and analyzed with a 2 × 2 × 3 within-subject repeated measures analysis of variance. RESULTS: Pre-workload muscle activity did not differ between surfaces and cognitive task conditions. However, greater muscle activity during post-workload balance assessment was found, specifically during the cognitive task. Cognitive task errors did not differ between surface and workload. CONCLUSIONS: The cognitive task after workload increased lower extremity muscular activity compared to quite standing, irrespective of the surface condition, suggesting an increased demand was placed on the postural control system as the result of both fatigue and cognitive task.

ABSTRACT

To provide a basis for the establishment of the commodity grade of Astragali Radix (AR), we compared the chemical components and the anti-fatigue effect of different grades of AR. The components of primary metabolites were analyzed by 1H NMR and the contents of five flavonoids were determined by HPLC-UV with different grades of AR. Fatigue efficacy of different grades of AR was compared. All the procedures were approved by the Laboratory Animal Ethics Committee of the Shanxi University. The results showed that the content of water soluble extracts (WSE) of the Grade Ⅱ AR was the lowest, and 21 compounds were identified through 1H NMR spectrum. There are 3 components showing a higher content in the Grade-top AR, and 7 components were higher in the Grade-Ⅳ, and 7 other components were higher in the Grade-Ⅱ AR. Total flavonoid content was the highest in Grade-Ⅱ but it was the lowest in the Grade-Ⅳ. Pharmacodynamic results showed that AR could significantly enhance the exhaustion time of rats and improve the biochemical indexes of serum and gastrocnemius muscle, and the best anti-fatigue effect was observed with Grade -Ⅱ AR. Therefore, chemical composition and efficacy index were used to evaluate the quality of different grades of AR, and the quality evaluation approach was established based on chemical and pharmacological effects to provide a scientific basis for the development of AR. The study may provide useful information for construction of the quality grade standard of AR.

ABSTRACT

This study was designed to explore the intervention of muscle fatigue in rats with Astragali Radix using 1H NMR metabolomics methods. The fatigue model was induced in rats by forced swimming plus food restriction, and the effects of Astragali Radix (3, 6 and 12 g·kg-1) were investigated using the exhaustive time of rat swimming. After 3 weeks, the gastrocnemius was collected for 1H NMR detection, and the anti-fatigue effects of Astragali Radix were explored using multivariate statistical analysis. Astragali Radix significantly improved the exhaustive swimming time of rats. Compared with control group, the levels of isoleucine, leucine, creatine, phosphatidylcholine, trimethylamine oxide, taurine, guanidinoacetate, AMP, inosine, histidine, hypoxanthine, anserine in rat gastrocnemius of model group were increased. While the levels of lactate, acetone, choline, glycerophosphocholine, glycine were decreased. These 6, 11, 5 potential biomarkers could be reversely regulated by treatment with Astragali Radix (high dose, middle dose, low dose), respectively. Metabolomics analysis revealed that Astragali Radix has a certain anti-fatigue effects and the mechanism may be related to regulation of amino metabolism.

Objective:To study the effects of compound schisandra extracts (CSE) (schisandra,astragalus,acanthopanax,and rhodiola)on the exhaustive swimming time and the levels of blood urea nitrogen(BUN),serum lactic acid(LD),liver glycogen and muscle glycogene,superoxide dismutase(SOD)activity,and malonaldehyde(MDA) level in the mice and to charify its anti-fatigue effect and the mechanism.Methods:Eighty male ICR mice were randomly divided into blank control group,50 mg·kg-1 CSE group,100 mg·kg-1 CSE group,and 200 mg·kg-1CSE group;there were 20 mice in each group.The mice were administered orally for 30 d.Then 10 mice were randomly selected for exhaustive swimming test in each group and the exhaustive swimming time of the mice was recorded.The remaining 10 mice in each group were used for 90 min swimming,then all the mice were sacrificed and the blood and tissue samples were taken for the measurement of the levels of BUN,LD,liver glycogen and muscle glycogen,the SOD activity and MDA level;the total inhibitory rate of oxidation of CSE in vitro was determined by linoleic acid-ferric thiocyanate method.Results:Compared with blank control group,the exhaustive swimming time of the mice in 50,100,and 200 mg·kg-1 CSE groups were significantly increased (P<0.01);the levels of BUN and LD of the mice in 100 and 200 mg·kg-1 CSE groups were significantly decreased (P<0.05 or P<0.01);the levels of liver glycogen and muscle glycogen of the mice in 100 and 200 mg·kg-1 groups were significantly increased(P<0.05 or P<0.01);whereas the SOD activities were significantly increased and the levels of MDA were decreased(P<0.05 or P<0.01).Compared with 100 mg·kg-1 CSE group,the levels of serum BUN and LD of the mice in 200 mg·kg-1 CSE group were decreased (P<0.01),and the levels of liver glycogen and muscle glycogen were increased(P<0.05).The total inhibitory rate of oxidation of 5 g·L-1CSE was 76.94%.Conclusion:CSE has an anti-fatigue effect and the mechanism may be related to anti-oxidation effect.
