Effects of epigallocatechin gallate, caffeine, and their combination on fat accumulation in high-glucose diet-fed Caenorhabditis elegans.

Epigallocatechin gallate (EGCG) and caffeine are inevitable to be ingested together in the process of drinking green tea. This study used Caenorhabditis elegans as an organism model to examine whether the binding of EGCG and caffeine could influence the fat-reduction effect. The results revealed that EGCG significantly reduced the Nile Red fluorescence intensity and the triglyceride/protein ratio of the C. elegans obesity model by 14.7% and 16.5%, respectively, while the effect of caffeine was not significant. Moreover, the degree of reduction in fluorescence intensity and triglyceride/protein ratio by EGCG + caffeine was comparable to that of EGCG. In the exploration of underlying mechanism, we found that EGCG and EGCG + caffeine treatments had no influence on food intake and energy expenditure of C. elegans. Their fat-reduction effects were dependent on the regulation of lipogenesis, as shown by the decreased expression of the sbp-1, fat-7, and daf-16 genes.

Purification of total flavonoids from Ginkgo biloba flowers with resin column chromatography and evaluation of antioxidant activities in vitro.

Purification of total flavonoids from Ginkgo biloba flowers (GBF) extracts were studied using six resins. Adsorption-desorption experiments indicated that polyamide resin is the most suitable resin. The optimal purification process of total flavonoids of GBF was as follows: a loading concentration of 5.85 mg/mL, a loading volume of 1 bed volume (BV), a loading flow rate of 2 BV/h, a water volume of 2.67 BV, and a desorption solution of 40% ethanol. Under these conditions, the maximum purity of total flavonoids was 37.1 ± 1.1%. The antioxidant activity of purified flavonoids was further evaluated in vitro. It showed that the 40% ethanol purified fraction (Fr. B) group had the strongest antioxidant activity of the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity concentration for 50% of maximal effect (EC50, 145.4 ± 13.8 µg/mL) and ferric reducing ability (2.5 ± 0.2 mM FeSO4 equivalent mg-1 Fr. B). In addition, at the concentration of 160 µg/mL, the Fr. B strikingly increased the viability rate of hydrogen peroxide stimulated PC-12 cells to normal levels (***p < 0.001). This method provides a basis for the application and development of GBF resources. It indicated that the purified GBF flavonoids can be used as a source of potential antioxidant.

Effects of Tingli dazao xiefei decoction on ventricular remodeling in model rats with heart failure after myocardial infarction through ACE2-Ang（-1-7）-Mas axis / 中国药房

OBJECTIVE To explore the mechanism of Tingli dazao xiefei decoction on ventricular remodeling in model rats with heart failure after myocardial infarction. METHODS The rat model of heart failure after myocardial infarction was established by ligation of anterior descending branch of left coronary artery， which was divided into 8 groups： sham operation group， model group， A779 group （1 mg/kg）， A779 （1 mg/kg）+Tingli dazao xiefei decoction equivalent-dose group （0.8 g/kg）， A779 （1 mg/kg） +Tingli dazao xiefei decoction high-dose group （1.6 g/kg）， Tingli dazao xiefei decoction equivalent-dose group （0.8 g/kg）， Tingli dazao xiefei decoction high-dose group （1.6 g/kg） and losartan potassium group （10 mg/kg）. Each group was given equal volume of distilled water or corresponding drugs intragastrically for 4 weeks. Masson staining was used to determine the distribution of collagen fibers in rat myocardium. The content of hydroxyproline （Hyp） in myocardium was determined by alkaline hydrolyzation. The expressions of type Ⅰ and Ⅲ collagen （COLⅠ， COLⅢ）in myocardium were detected by immunohisto-chemistry. Myocardial fibrosis-related indexes such as matrix metalloproteinase-2 （MMP-2）， MMP-9， tissue inhibitor of metalloproteinase-1 （TIMP-1） and soluble suppression of tumorigenicity-2 （sST-2） were detected by ELISA. The protein expressions of angiotensin converting enzyme 2-angiotensin-（1-7）-Mas [ACE2-Ang-（1-7）-Mas] axis were detected by Western blot. RESULTS Compared with sham operation group， myocardial cells in model group and A779 group were disordered， collagen fiber deposition was significantly increased and myocardial fibrosis was obvious； the Hyp content and MMP-2， MMP-9， sST-2 levels were increased， and COL Ⅰ and COL Ⅲ positive expressions were significantly enhanced； TIMP-1 level， protein expressions of ACE2， Ang-（1-7） and Mas were significantly decreased （P＜0.05）. Compared with model group， above indexes of Tingli dazao xiefei decoction equivalent-dose and high-dose groups were improved to different extents. Compared with A779 group， A779+Tingli dazao xiefei decoction equivalent-dose and A779+high-dose groups could improve myocardial arrangement and collagen distribution， reduce the Hyp content and MMP-2， MMP-9 levels， reduce positive expressions of COL Ⅰ and COL Ⅲ （P＜0.05）， but couldn’t improve Ang-（1-7） and Mas protein expression. CONCLUSIONS Tingli dazao xiefei decoction can improve ventricular remodeling in myocardial failure model rats after myocardial infarction by improving the expression of ACE2- Ang（- 1-7）-Mas axis proteins.

Clinical Application Analysis of Da Qinjiaotang Based on Ancient and Modern Literature / 中国实验方剂学杂志

Da Qinjiaotang is a common classical prescription for the treatment of stroke. It originates from Collection of Writings on the Mechanism of Disease， Suitability of Qi， and the Safeguarding of Life as Discussed in the Basic Questions （《素问病机气宜保命集》） by physician LIU Wansu， and is composed of Gentianae Macrophyllae Radix， Glycyrrhizae Radix et Rhizoma， Chuanxiong Rhizoma， Angelicae Sinensis Radix， Paeoniae Radix Alba， Asari Radix et Rhizoma， Notopterygii Rhizoma et Radix， Saposhnikoviae Radix， Scutellariae Radix， Gypsum Fibrosum， Angelicae Dahuricae Radix， Atractylodis Macrocephalae Rhizoma， Rehmanniae Radix， Rehmanniae Radix Praeparata， Poria， and Angelicae Pubescentis Radix. Doctors of all dynasties have disputed the composition principle of the prescription and argued whether its treatment of stroke belongs to the theory of "internal wind" or "external wind". Through collating and analyzing ancient and modern literature related to the indications of Da Qinjiaotang， this paper was dedicated to the origin of syndrome differentiation and treatment of Da Qinjiaotang. According to LIU Wansu's original works， Da Qinjiaotang is a prescription for the treatment of "internal wind"， and in the prescription， wind medicinal herbs such as Gentianae Macrophyllae Radix， Notopterygii Rhizoma et Radix and Angelicae Pubescentis Radix removes stagnation， clears sweat pore， and makes qi and blood channels flow smoothly. However， later generations， affected by the idea of "external wind"， believe that this prescription is used for the treatment of "external wind". Ancient physicians gradually supplemented the symptoms of stroke， such as wry eye and mouth， hemibody pain and limb numbness， which were treated by Da Qinjiaotang， and Da Qinjiaotang was also applied to the treatment of other diseases， such as tendon dryness， convulsion and arthralgia. Modern doctors still explain the disease pathogenesis from the theory of "external wind" as deficiency in channels and collaterals and the entry of pathogenic wind， and the prescription has the effect of dispersing wind， clearing heat and nourishing and activating blood. In clinical practice， Da Qinjiaotang is mainly used to treat cerebrovascular diseases and peripheral facial paralysis in nervous system diseases， gouty arthritis and rheumatic arthritis in the rheumatic immune system and skin diseases. The above findings facilitate the research and development of Da Qinjiaotang.

Research Progress of Active Components of Traditional Chinese Medicine in Treatment of Hyperlipidemia by Activating PPARα Pathway / 中国实验方剂学杂志

Hyperlipidemia is a dyslipidemia caused by dyslipidemia of lipid metabolism， which can be divided into primary and secondary types. The current clinical diagnostic criteria are mainly changes in lipid levels， which are the inducers of high-risk cardiovascular diseases such as atherosclerosis， pancreatitis and coronary heart disease. As a key target in lipid metabolism， peroxisome proliferator-activated receptor α （PPARα） is involved in a variety of metabolic activities， including fatty acid degradation， synthesis， transport， storage， lipoprotein metabolism， etc. Activation of PPARα can maintain the balance of lipid metabolism through a variety of ways， which is an important way to treat hyperlipidemia. At present， chemical drugs such as statins and bettes are mainly used in the clinical treatment of hyperlipidemia. Although they can slow down the disease to a certain extent， there are many adverse reactions and drug resistance. By reviewing the literature in recent years， the author found that the activation of PPARα pathway by traditional Chinese medicine in the treatment of hyperlipidemia has significant effect and small adverse reactions. The lipid-lowering active ingredients include flavonoids， alkaloids， phenols， terpenoids and other compounds. These active components mainly affect the expression of downstream effectors through the activation of PPARα pathway， thereby inhibiting the synthesis of total cholesterol and promoting fatty acid oxidation， and play a role in the treatment of hyperlipidemia. In this paper， we systematically reviewed the structure types and mechanism of active components of traditional Chinese medicine that activate PPARα pathway， so as to provide guidance for the rational development and clinical application of lipid-lowering traditional Chinese medicine new drugs.

Neuroprotective Effect of Chinese Medicinal Compounds Effective in Supplementing Qi and Resolving Phlegm on Alzheimer's Disease： A Review / 中国实验方剂学杂志

Alzheimer's disease （AD） is a common chronic degenerative neurological disease in the elderly and is mainly manifested by the impairment of cognition， memory， and behaviors. At present， the etiology and pathogenesis of this disease have not been fully unraveled， and the research on related drugs for alleviating the disease progression is still in clinical trials. Traditional Chinese medicine （TCM） believes that the elderly have reduced visceral function. Deficiency of vital Qi and turbid phlegm obscuring orifices are the core pathogenesis of AD. Qi deficiency and phlegm obstruction run through the whole pathological process of AD， and the important role of therapeutic principles of supplementing Qi and resolving phlegm is emphasized in treatment. In recent years， the Chinese medicinal compounds effective in supplementing Qi and resolving phlegm represented by Kaixin Powder have been widely used in the clinical and basic research of AD. As reported， in addition to the improvement of the cognitive function of AD， it can also reduce β amyloid （Aβ） deposition， inhibit tau hyperphosphorylation， improve neurotransmitter activity， regulate neuronal synaptic plasticity， resist oxidant stress injury， and inhibit the central inflammatory response and neuronal apoptosis. Therefore， this article reviewed and analyzed the theoretical basis of the treatment of AD by supplementing Qi and resolving phlegm and the mechanism of Chinese medicinal compounds effective in supplementing qi and resolving phlegm against AD to provide theoretical support and a scientific basis for the clinical application of TCM in the prevention and treatment of AD.

Antidepressant Effects of Oligosaccharides and Polysaccharides in Chinese Medicine： A Review / 中国实验方剂学杂志

Depression is a common psychiatric disease that seriously affects the physical and mental health and quality of life of patients， and has become one of the major global disease burdens. The etiology of depression is intricate， and despite extensive research， its pathogenesis remains inconclusive， resulting in various hypotheses of its onset mechanisms. Presently， the primary approach for clinically treating depression involves the utilization of selective inhibitors targeting the reuptake of monoamine neurotransmitters within the central nervous system. However， these drugs are generally characterized by delayed onset of action， limited efficacy and obvious resistance. Recently， researchers have gradually turned their attention to the development of antidepressant drugs with novel mechanisms. Notably， as a category of abundantly available active ingredients in Chinese medicine， numerous pharmacological studies have demonstrated that oligosaccharides and polysaccharides possess promising antidepressant properties， such as Morindae Officinalis Radix oligosaccharides， Polygalae Radix oligosaccharide esters， Poria polysaccharides and Astragali Radix polysaccharides. Their pharmacological mechanisms are various， including enhancing the levels of monoamine neurotransmitters in the brain， inhibiting the hyperactivation of the hypothalamic-pituitary-adrenal axis（HPA axis）， increasing the expression of neurotrophic factors（NTF）， regulating immune-inflammatory responses and modulating the microbiota-gut-brain axis. Therefore， oligosaccharides and polysaccharides from Chinese medicine have become a vital source of safe and effective novel antidepressant candidates due to the potential to improve depression through integrated regulatory effects. This article aims to provide a comprehensive and systematic review of recent progress to contribute to the elucidation of the mechanisms underlying the antidepressant effects of oligosaccharides and polysaccharides derived from Chinese medicine.

Study on the action mechanism of the peptide compounds of Wuguchong on diabetic ulcers, based on UHPLC-Q-TOF-MS, network pharmacology and experimental validation.

ETHNOPHARMACOLOGICAL RELEVANCE: Diabetic foot ulcers mainly refer to people who are initially diabetic and do not have peripheral neuropathy or peripheral vascular disease, but have developed foot infection, septicemia, and ulceration. Diabetic trauma disease is characterized by high sugar and very slow wound healing, which is the reason why some patients with severe diabetic trauma require amputation. Prolonged hyperglycemia can lead to changes in bodily functions and endocrine changes, which can lead to permeability damage of epidermal tissue structure, microvascular damage and, in more severe cases, nerve damage, which are also the main causes of diabetic trauma. Small molecule peptides have various biological activities, such as: lowering blood pressure, antibacterial and wound healing activities, etc. It is a drug recorded in classical Chinese medicine, it is safer to use natural active peptides to treat wounds compared to the listed drugs, and there are no side effects in its use.The wound healing effect of Wuguchong dry product has been confirmed but the mechanism is still unclear, whether it is related to the small molecule active peptides contained in it remains to be studied. AIM OF STUDY: Objective To investigate the potential mechanism of the peptide compounds of Wuguchong (PCW) on diabetic wound healing and the relevant targets in the pathway associated with the treatment of diabetic ulcers using a systematic pharmacological and pharmacological experimental validation approach. METHODS: 1) PCW was prepared by enzymatic digestion of TCMW and analyzed by UHPLC-Q-TOF-MS. 2) Further screening of the active chemical components of PCW using PubChem, Swiss Target Prediction data. 3) Prediction of its targets using Drug Bank, CTD, and Genecards databases. 4) Construct protein/gene interactions network diagrams for PCWs acting by using Cytoscape 3.7.0 software. 5) GO and KEGG analysis of PCW targets were performed by David database. 6) Validated by AO/EB staining, scratching and in vitro tube formation methods. 7) Explored the mechanism of PCW to promote diabetic wound healing by protein blotting and immunohistochemical detection of relevant protein expression. RESULTS: and finally: 1) After the above screening, 81 active ingredients of PCW and 94 targets acting on diabetic ulcers were obtained. 2) 30 biological processes, 30 cellular compositions and 30 molecular functions were obtained by GO analysis; 28 signaling pathways were obtained by KEGG analysis. 3) The results of AO/EB staining assay, scratch assay and in vitro tube-forming assay showed that PCW has significant pro-vascular endothelial cell proliferation and pro-angiogenic effects in vitro. CONCLUSIONS: The results of this study confirmed the effect of the PCW in treating diabetic ulcers to a certain extent, and further revealed its mechanism of action in depth, which provides a new reference for the next step of Chinese medicine in treating diabetic ulcers.

Pathogenesis of Gouty Arthritis and Intervention with Chinese Medicines： A Review / 中国实验方剂学杂志

Gouty arthritis （GA） is the metabolic rheumatism caused by purine metabolism disorder， which can be acute or chronic. The main manifestations of GA include recurrent redness， swelling， heat pain， and dysfunction of the affected joints. According to the theory of modern medicine， GA is closely associated with the increase in uric acid， the participation of inflammatory cytokines， the weakening of antioxidant response， apoptosis， and the imbalance of intestinal flora and bone metabolism， whereas the specific pathogenesis remains unclear. GA is characterized by easy diagnosis， difficult treatment， and high recurrence rate， which seriously affects the life quality of patients. Colchicine， corticosteroids， non-steroidal anti-inflammatory drugs， and selective cyclooxygenase-2 inhibitors are the commonly used western medicines for this disease， which demonstrate remarkable short-term therapeutic effect. However， long-term use of these medicines will bring serious adverse reactions. Chinese medicines， with high safety and causing few adverse reactions， have a variety of active components which can act on multiple pathways and targets to exert synergistic effects， thus attracting wide attention. This paper systematically reviews the literature reporting the Chinese medicines in improving antioxidant response， reducing chondrocyte apoptosis， and regulating intestinal flora and bone metabolism， aiming to further clarify the pathogenesis of GA and provide a scientific basis for the clinical application of Chinese medicines in the prevention and treatment of GA.
