Methods: Myocardial cells from 1- to 2-day-old neonatal rats were cultured in Dulbecco's modified Eagle's medium low-glucose and Ham's F12 medium (1:1), and the cellular injury was induced by H2O2. The ultra-filtration extract mixture from Angelica sinensis and Hedysarurn po/ybotrys was given in three doses of 3.75, 7.5, and 15 mg/mL. Morphological changes of cardiomyocytes were observed by microscope. Survival rate of myocardial cells was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (Ml-r) assay. The cardiomyocyte damages were estimated by detecting lactate dehydrogenase (LDH) and creatine kinase (CK) releases in the medium, superoxide dismutase (SOD) activities, and intracellular malondialdehyde (MDA) and myeloperoxidase (MPO) contents. The levels of caspase-3 and heat shock protein 70 (hsp70) mRNA expression in cardiomyocytes were measured by reverse transcription polymerase chain reaction. Results: The EDBD could protect the cardiomyocytes from H202 injury in a dose- dependent manner (3.75, 7.50, and 15.00 mg/mL). The EDBD could significantly decrease LDH and CK leakages and intracellular MDA and MPO contents, increase SOD activity, up-regulate hsp70 expression, and down-regulate caspase-3 expression. Conclusion: The EDBD has protection on cardiomyocytes injured by H202 through improving cell antioxidant ability, up-regulating hsp70 expression, and inhibiting caspase-3 activity.展开更多

Goto-Kakizaki(GK) rats were randomly allocated to a diabetes atherosclerosis(DA) group, a DBD group, and an ABC group(10 per group), which were all high-fat diet-fed. The treated rats were administered DBD(4 g/kg) or ABCs(in amounts equal to those present in DBD) once daily for 28 d, and a control group of Wistar rats were administered vehicle. Body mass gain, fasting blood glucose, and homeostasis assessment of insulin resistance(HOMAIR) were measured. Serum triglyceride(TG), cholesterol(CHOL), high density lipoprotein-cholesterol(HDL-C), low-density lipoprotein-cholesterol(LDLC) and tumor necrosis factor-α(TNF-α) concentrations were determined. Hematoxylin and eosin staining and microscopy were used to characterize the abdominal aorta and the expression of lipogenic genes was quantified in this vessel.RESULTS: Seven ABCs were identified in rat serum:ferulic acid, formononetin, calycosin, astragaloside,caffeic acid, ligustilide, and butyphthalide. DBD significantly reduced HOMA-IR, the serum concentrations of TG, CHOL, and LDL-C, and the expression of the lipogenic genes monocyte chemotactic protein1, Fas, intercellular adhesion molecule 1, and Cd36 in aorta;and significantly increased the mRNA expression of Scd1 in aorta.CONCLUSION: DBD affects lipid metabolism in the early stage of atherosclerosis in diabetic GK rats,with the mechanism likely involving the regulation of lipid metabolic genes in vessels. The contribution of ABCs to the effect of DBD on lipid metabolism was 24%-101%.展开更多

文摘Objective: To investigate whether the administration of the ultra-filtration extract from Danggui Buxue Decoction (当归补血汤, EDBD) was able to protect cardiomyocytes from oxidative injury of rats induced by hydrogen peroxide (H2O2) and its potential mechanism. Methods: Myocardial cells from 1- to 2-day-old neonatal rats were cultured in Dulbecco's modified Eagle's medium low-glucose and Ham's F12 medium (1:1), and the cellular injury was induced by H2O2. The ultra-filtration extract mixture from Angelica sinensis and Hedysarurn po/ybotrys was given in three doses of 3.75, 7.5, and 15 mg/mL. Morphological changes of cardiomyocytes were observed by microscope. Survival rate of myocardial cells was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (Ml-r) assay. The cardiomyocyte damages were estimated by detecting lactate dehydrogenase (LDH) and creatine kinase (CK) releases in the medium, superoxide dismutase (SOD) activities, and intracellular malondialdehyde (MDA) and myeloperoxidase (MPO) contents. The levels of caspase-3 and heat shock protein 70 (hsp70) mRNA expression in cardiomyocytes were measured by reverse transcription polymerase chain reaction. Results: The EDBD could protect the cardiomyocytes from H202 injury in a dose- dependent manner (3.75, 7.50, and 15.00 mg/mL). The EDBD could significantly decrease LDH and CK leakages and intracellular MDA and MPO contents, increase SOD activity, up-regulate hsp70 expression, and down-regulate caspase-3 expression. Conclusion: The EDBD has protection on cardiomyocytes injured by H202 through improving cell antioxidant ability, up-regulating hsp70 expression, and inhibiting caspase-3 activity.

文摘OBJECTIVE: To determine the constituent compounds of Danggui buxue decoction(DBD) involved and the potential mechanisms mediating its effects, with specific reference to lipids playing a role in the initiation of diabetic atherosclerosis.METHODS: Liquid chromatography-tandem mass spectrometry was used to identify and quantify the absorbed bioactive compounds(ABCs) present in DBD. Goto-Kakizaki(GK) rats were randomly allocated to a diabetes atherosclerosis(DA) group, a DBD group, and an ABC group(10 per group), which were all high-fat diet-fed. The treated rats were administered DBD(4 g/kg) or ABCs(in amounts equal to those present in DBD) once daily for 28 d, and a control group of Wistar rats were administered vehicle. Body mass gain, fasting blood glucose, and homeostasis assessment of insulin resistance(HOMAIR) were measured. Serum triglyceride(TG), cholesterol(CHOL), high density lipoprotein-cholesterol(HDL-C), low-density lipoprotein-cholesterol(LDLC) and tumor necrosis factor-α(TNF-α) concentrations were determined. Hematoxylin and eosin staining and microscopy were used to characterize the abdominal aorta and the expression of lipogenic genes was quantified in this vessel.RESULTS: Seven ABCs were identified in rat serum:ferulic acid, formononetin, calycosin, astragaloside,caffeic acid, ligustilide, and butyphthalide. DBD significantly reduced HOMA-IR, the serum concentrations of TG, CHOL, and LDL-C, and the expression of the lipogenic genes monocyte chemotactic protein1, Fas, intercellular adhesion molecule 1, and Cd36 in aorta;and significantly increased the mRNA expression of Scd1 in aorta.CONCLUSION: DBD affects lipid metabolism in the early stage of atherosclerosis in diabetic GK rats,with the mechanism likely involving the regulation of lipid metabolic genes in vessels. The contribution of ABCs to the effect of DBD on lipid metabolism was 24%-101%.

文摘Colon cancer-related anemia(CCRA)is mainly caused by systemic inflammation,intestinal bleeding,iron deficiency and chemotherapy-induced myelosuppression in colon cancer.However,the best therapeutic schedule and related mechanism on CCRA were still uncertain.Studies on blood enrichment and anti-tumor effects of combined Danggui Buxue Decoction(DBD),Fe and rhEPO based on CCRA and gut microbiota modulation were conducted in this paper.Here,CCRA model was successfully induced by subcutaneous inoculation of CT-26 and i.p.oxaliplatin,rhEPO+DBD high dosage+Fe(EDF)and rhEPO+DBD high dosage(ED)groups had the best blood enrichment effect.Attractively,EDF group also showed antitumor activity.The sequencing results of gut microbiota showed that compared to P group,the relative abundances of Lachnospiraceae and opportunistic pathogen(Odoribacter)in ED and EDF groups were decreased.Interestingly,EDF also decreased the relative abundances of cancer-related bacteria(Helicobacter,Lactococcus,Alloprevotella)and imbalance-inducing bacteria(Escherichia-Shigella and Parabacteroides)and increased the relative abundances of butyrate-producing bacteria(Ruminococcaceae_UCG-014),however,ED showed the opposite effects to EDF,this might be the reason of the smaller tumor volume in EDF group.Our findings proposed the best treatment combination of DBD,rhEPO and Fe in CCRA and provided theoretical basis and literature reference for CCRA-induced intestinal flora disorder and the regulatory mechanism of EDF.
