RESUMO
Background: The incidence of glycolipid metabolic diseases is extremely high worldwide, which greatly hinders people's life expectancy and patients' quality of life. Oxidative stress (OS) aggravates the development of diseases in glycolipid metabolism. Radical oxygen species (ROS) is a key factor in the signal transduction of OS, which can regulate cell apoptosis and contribute to inflammation. Currently, chemotherapies are the main method to treat disorders of glycolipid metabolism, but this can lead to drug resistance and damage to normal organs. Botanical drugs are an important source of new drugs. They are widely found in nature with availability, high practicality, and low cost. There is increasing evidence that herbal medicine has definite therapeutic effects on glycolipid metabolic diseases. Objective: This study aims to provide a valuable method for the treatment of glycolipid metabolic diseases with botanical drugs from the perspective of ROS regulation by botanical drugs and to further promote the development of effective drugs for the clinical treatment of glycolipid metabolic diseases. Methods: Using herb*, plant medicine, Chinese herbal medicine, phytochemicals, natural medicine, phytomedicine, plant extract, botanical drug, ROS, oxygen free radicals, oxygen radical, oxidizing agent, glucose and lipid metabolism, saccharometabolism, glycometabolism, lipid metabolism, blood glucose, lipoprotein, triglyceride, fatty liver, atherosclerosis, obesity, diabetes, dysglycemia, NAFLD, and DM as keywords or subject terms, relevant literature was retrieved from Web of Science and PubMed databases from 2013 to 2022 and was summarized. Results: Botanical drugs can regulate ROS by regulating mitochondrial function, endoplasmic reticulum, phosphatidylinositol 3 kinase (PI3K)/protein kinase B (AKT), erythroid 2-related factor 2 (Nrf-2), nuclear factor κB (NF-κB), and other signaling pathways to improve OS and treat glucolipid metabolic diseases. Conclusion: The regulation of ROS by botanical drugs is multi-mechanism and multifaceted. Both cell studies and animal experiments have demonstrated the effectiveness of botanical drugs in the treatment of glycolipid metabolic diseases by regulating ROS. However, studies on safety need to be further improved, and more studies are needed to support the clinical application of botanical drugs.
RESUMO
OBJECTIVE: To investigate the effects of erlong zuoci (ELZC) pills and its disassembled prescriptions (Shudi-huang-Zexie group and Zexie group) on the enzymatic activity and protein expression changes of the key apoptosis molecules in the gentamycin injured hair cells. METHOD: The model of gentamycin induced ototoxicity in mice cochlear primary cultures was copied. Cochlear organotypic cultures of postnatal day 3-5 (P3-P5) mice were treated with gentamycin alone or in combination with ELZC pills, Shudihuang-Zexie group or Zexie group respectively. The enzymatic activity of Caspase-9 and Caspase-3 was determined by means of fluorescence staining in situ. The protein expression of Bcl-2 and Bax in the hair cell area was examined by immunofluorescence in normal and treated specimens. RESULT: Average optical density analysis indicated that, compared to the normal group, 0.03 mmol x L(-1) gentamycin could significantly activate Caspase-9 and Caspase-3, downregulate the ratio of Bcl-2 and Bax protein expression. Compared to the gentamycin model group, ELZC pills significantly inhibited the enzymatic activity of Caspase-9 and upregulated the ratio of Bcl-2 and Bax protein expression, showing inhibition trend toward the enzymatic activity of Caspase-3. Both Shudihuang-Zexie group and Zexie group could effectively inhibit the enzymatic activity of Caspase-9 and Caspase-3, upregulate the ratio of Bcl-2 and Bax protein expression. CONCLUSION: ELZC pills, Shudihuang-Zexie group and Zexie group can effectively protect hair cells from gentamycin by correcting the abnormal changes of the mitochondrion-dependent signal transduction pathway.

OBJECTIVE: To explain functions, differences and coordination of three divided combinations of the "Erxian decoction", the famous traditional Chinese formula, on the effective sites of gonad gland at the cell level. METHOD: The effects of Erxian decoction and its main disassembled prescriptions, "Kidney Warming", "Yin Nourishing" and "Chong-ren Adjusting", on the level of testosterone (T) progesterone (P) estradiol (E2), respectively secreted by the primary culture Leydig cell, luteal cell and granulosa cell, were measured by radioimmunoassay. RESULT: (1) Erxian decoction could stimulate the T secretion while its three main disassembled prescriptions would seem no individual promoting effect on the secretion of T. (2) Erxian decoction and the "Kidney Warming" had the stimulating effect on P secretion, and the action of the whole formula being better than that of the "Kidney Warming". (3) Erxian decoction and its main disassembled prescriptions had the stimulating effect on E2 secretion, especially the whole formula. CONCLUSION: Erxian decoction can stimulate the secretion of T of the Leydig cell, P of luteal cell and E2 of granulosa cell. It can be seen that the effect of the whole formula is better than that of its main disassembled prescriptions.
