ABSTRACT
Guided by the development of new medical science proposed by Ministry of Education and the "Education and Training Plan for Excellent Doctors 2.0", shifted from treatment-oriented to whole life-health cycle, we have explored curriculum ideological and political education in metabolic-related curriculum chain. Firstly, we constructed a core teaching team and had the training of curriculum ideological and political education. The top-level design was made with the integration of moral education into medical education. Secondly, the syllabus was comprehensively revised, containing the connotation of "morality education". The elements relevant to curriculum ideological and political education hidden behind professional courses were excavated. Finally, the mixed teaching mode of online combining with offline was carried out. Metabolism-related curriculum chain, focused on "metabolism, diabetes, obesity and patient education", formed a progressive link from basic medical science to practice to clinical, strengthening the "prevention, treatment and health care" based "one health" philosophy and giving full play to the implicit curriculum ideological and political education hidden behind professional courses. Our practice shows that the implementation of curriculum ideological and political education in metabolism-related curriculum has been accepted by students, and curriculum ideological and political education has been become part of professional courses. The "gene chimera" mode for curriculum ideological and political education incorporation into professional courses needs to be infiltrated imperceptibly, and the effect will be visualized in the future.
ABSTRACT
Recent studies have revealed that the property of drug is mainly associated with the body's substance and energy metabolism. The present study aimed to evaluate the drug property of Poria, called Fuling (FL) in traditional Chinese medicine (TCM), in terms of its effects on the substance and energy metabolism in rat models of cold-deficiency and heat-deficiency syndromes, compared with Aconiti Lateralis Radix Praeparaia, called Fuzi (FZ) in TCM, with hot property, and Anemarrhenae Rhizoma, called Zhimu (ZM) in TCM, with cold property, as reference drugs, respectively. The appearance score, toe and rectal temperatures of the animals treated were assessed at different time points. Several indices in vivo correlated with substance and energy metabolism (glucokinas, phosphoglycerate kinase, cytochrome c reductase, cytochrome c oxydase, and Na-K-ATPase), endocrine system (triiodothyronine, thyroxine, and 17-hydroxycorticosteroid), nervous system (acetylcholin esterase), and cyclic nucleotide system were determined. The changes in appearance score and indices in vivo suggested the successful establishment of cold-deficiency and heat-deficiency syndrome models. FZ reversed the decreased levels of indices (substance and energy metabolism and endocrine system) and alleviated the syndrome of cold-deficiency model, and ZM showed obviously therapeutic effect on heat-deficiency syndrome (appearance score, substance and energy metabolism, and endocrine system). FL could alleviate cold-deficiency syndrome and raise the decreased levels of glucokinas, phosphoglycerate kinase, cytochrome c reductase and triiodothyronine in cold-deficiency model, but had no significant effect on heat-deficiency syndrome. Drug property of FL was inferred as trending to "flat and warm", which still need further study. It was advisable to adopt both cold-deficiency and heat-deficiency models to study the drugs with "flat" property.

This article was aimed to study the impact on substance and energy metabolism by chemical split fractions of Mori Cortex among hypoglycemic diabetic mouse model, in order to explain the new hypothesis of the science connotation in nature and flavor of traditional Chinese medicine (TCM). Male Kunming mice were intraperitoneally injected with a large dose of streptozotocin (STZ) (170 mg·kg-1) to establish type 1 diabetes mellitus mouse model. Medication was given consecutively for four weeks. The enzyme-linked immunesorbent assay (ELISA) was used to detect glucosekinase (GCK), glycogen phosphorylase (PYGL), pyruvate dehydrogenase (PDH), α-ketoglutarate dehydrogenase (α-KGDHC), phosphoglycerate kinase (PGK), acetyl coenzyme A (acetyl-CoA), adenylate kinase (ADK), fumarase (FUM), cytochrome C reductase (CCR), cytochrome C oxidase (COX) and other indicators. Enzymatic detection was used to determine the content of ATP coenzyme (ATPs), the content and ratio of NAD and NADH, the content of myocardial cell Na+-K+ ATP enzyme, as well as the content of ATP and ADP. The results showed that in the model group, the expression of PYGL was increased; and the expressions of GCK and PDH were decreased. It prompted that the source of glucose increased and the expelling of glucose decreased. The glucose level was increased. The COX expression was reduced and the respiratory chain was blocked. It regulated oxidative phosphorylation and the substrate phosphorylation level. It upregulated the expression of CCR, ATPs, NAD+, PGK, α-KGDHC and ADK. However, the expression of FUM was decreased. The activity of Na+-K+ ATPase was decreased significantly. At last, the metabolic disorders appeared. Mori Cortex aqueous extracts and the chemical split fractions significantly increased the GCK and PDH level in substance metabolism among diabetic mice. The levels of PYGL, α-KGDHC, PGK and acetyl-CoA were decreased (P < 0.05, or P <0.01). Meanwhile, it increased ATP and FUM, myocardial cell Na+-K+ ATP enzyme, and COX level in the energy metabolism (P < 0.05). It decreased the level of NAD+, CCR and ATPs (P < 0.05, or P <0.01). It was concluded that both the aqueous extracts and chemical split fractions of Mori Cortex can effectively improve the substance and energy metabolism disorders of diabetic mouse model. This effect may be related to the cold nature of Mori Cortex.
ABSTRACT
OBJECTIVE: To study the effects of Dendrobium officinale Kimura et Migo on the rats substance metabolism and anti-exercise fatigue capacity in the exercise training. METHODS: High-intensity endurance training rat was as a model. Divided the 6-week-old male (42 d age) Wistar rats 55 into 5 groups of 10 (removed the rats, which are not meeting the requirement): still group (group C), exercise group (group T), exercise ig low-dose Dendrobium officinale Kimura et Migo group of (group TML), exercise ig middle-dose of Dendrobium officinale Kimura et Migo group (group TMM), exercise ig high-dose of Dendrobium officinale Kimura et Migo group (group TMH). Gavage using professional device ig once a day, group TML, Group TMM, group TMH ig dose was 1.5, 3, 4. 5 g · kg-1 · d-1, the ig volume 5 mL · kg-1, Group C and group T were added to ig the same amount of saline. For 24 h after the last training, measured weight, exhaustive swimming time, Hemoglobin and other biochemical markers. RESULTS: The TM each weight no significant differences, and greater than the group T(P < 0.05) less than group C(P < 0.05). TM swimming time is longer than the group C and group T(P < 0.01), and the dose increased and extended. Prolonged exhaustive exercise lead to liver glycogen, muscle glycogen reserves decreased(group T(P < 0.01), groups TM(P < 0.05) lower than in group C. TM each group of liver glycogen [P < 0.05), inositol the original (P < 0.01] higher than the group T, no significant differences between each group of the TM, with the dose increase and higher). In addition, blood urea nitrogen rise[group T(P < 0.01) and groups TM(P < 0.05) blood urea nitrogen higher than in group C. Groups TM is lower than the group T(P < 0.05), TM each non-significant difference]. Hemoglobin decreased [group T(P < 0.01), groups TM(P < 0.05) lower than in group C. Groups TM is higher than the group T(P < 0.05), no significant difference between the TM each]. CONCLUSION: Dendrobium officinale Kimura et Migo supplement can promote protein synthesis, inhibition of amino acid and protein degradation, thereby increasing the hemoglobin content and glycogen reserves, enhanced resistance to fatigue, it has a multi-target, multi-channel features.
