Chrysin alleviates cerebral ischemia-reperfusion injury by inhibiting ferroptosis in rats / 中国中药杂志

The purpose of this study is to investigate whether chrysin reduces cerebral ischemia-reperfusion injury(CIRI) by inhi-biting ferroptosis in rats. Male SD rats were randomly divided into a sham group, a model group, high-, medium-, and low-dose chrysin groups(200, 100, and 50 mg·kg~(-1)), and a positive drug group(Ginaton, 21.6 mg·kg~(-1)). The CIRI model was induced in rats by transient middle cerebral artery occlusion(tMCAO). The indexes were evaluated and the samples were taken 24 h after the operation. The neurological deficit score was used to detect neurological function. The 2,3,5-triphenyl tetrazolium chloride(TTC) staining was used to detect the cerebral infarction area. Hematoxylin-eosin(HE) staining and Nissl staining were used to observe the morphological structure of brain tissues. Prussian blue staining was used to observe the iron accumulation in the brain. Total iron, lipid pero-xide, and malondialdehyde in serum and brain tissues were detected by biochemical reagents. Real-time quantitative polymerase chain reaction(RT-qPCR), immunohistochemistry, and Western blot were used to detect mRNA and protein expression of solute carrier fa-mily 7 member 11(SLC7A11), transferrin receptor 1(TFR1), glutathione peroxidase 4(GPX4), acyl-CoA synthetase long chain family member 4(ACSL4), and prostaglandin-endoperoxide synthase 2(PTGS2) in brain tissues. Compared with the model group, the groups with drug intervention showed restored neurological function, decreased cerebral infarction rate, and alleviated pathological changes. The low-dose chrysin group was selected as the optimal dosing group. Compared with the model group, the chrysin groups showed reduced content of total iron, lipid peroxide, and malondialdehyde in brain tissues and serum, increased mRNA and protein expression levels of SLC7A11 and GPX4, and decreased mRNA and protein expression levels of TFR1, PTGS2, and ACSL4. Chrysin may regulate iron metabolism via regulating the related targets of ferroptosis and inhibit neuronal ferroptosis induced by CIRI.

Danhong Injection Up-regulates miR-125b in Endothelial Exosomes and Attenuates Apoptosis in Post-Infarction Myocardium / 中国结合医学杂志

OBJECTIVE@#To investigate the involvement of endothelial cells (ECs)-derived exosomes in the anti-apoptotic effect of Danhong Injection (DHI) and the mechanism of DHI-induced exosomal protection against postinfarction myocardial apoptosis.@*METHODS@#A mouse permanent myocardial infarction (MI) model was established, followed by a 14-day daily treatment with DHI, DHI plus GW4869 (an exosomal inhibitor), or saline. Phosphate-buffered saline (PBS)-induced ECs-derived exosomes were isolated, analyzed by miRNA microarray and validated by droplet digital polymerase chain reaction (ddPCR). The exosomes induced by DHI (DHI-exo), PBS (PBS-exo), or DHI+GW4869 (GW-exo) were isolated and injected into the peri-infarct zone following MI. The protective effects of DHI and DHI-exo on MI hearts were measured by echocardiography, Masson's trichrome staining, and TUNEL apoptosis assay. The Western blotting and quantitative reverse transcription PCR (qRT-PCR) were used to evaluate the expression levels of miR-125b/p53-mediated pathway components, including miR-125b, p53, Bak, Bax, and caspase-3 activities.@*RESULTS@#DHI significantly improved cardiac function and reduced infarct size in MI mice (P<0.01), which was abolished by the GW4869 intervention. DHI promoted the exosomal secretion in ECs (P<0.01). According to the results of exosomal miRNA microarray assay, 30 differentially expressed miRNAs in the DHI-exo were identified (28 up-regulated miRNAs and 2 down-regulated miRNAs). Among them, DHI significantly elevated miR-125b level in DHI-exo and DHI-treated ECs, a recognized apoptotic inhibitor impeding p53 signaling (P<0.05). Remarkably, treatment with DHI and DHI-exo attenuated apoptosis, elevated miR-125b expression level, inhibited capsase-3 activity, and down-regulated the expression levels of proapoptotic effectors (p53, Bak, and Bax) in post-MI hearts, whereas these effects were blocked by GW4869 (P<0.05 or P<0.01).@*CONCLUSION@#DHI and DHI-induced exosomes inhibited apoptosis, promoted the miR-125b expression level, and regulated the p53 apoptotic pathway in post-infarction myocardium.

Development of Two-Dimensional Liquid Chromatography Coupled with Tandem Mass Spectrometry for Identification of Extracted Proteins of Rice Leaves: Hydrophilic Interaction-Reversed-phase Approach / 分析化学

A two-dimensional liquid chromatography method was developed for the analysis of rice leaves proteomics based on the coupling of hydrophilic interaction liquid chromatography-reversed-phase liquid chromatography with online tandem mass spectrometry. The influence of pH value of chromatographic mobile phase on the orthogonality of the hydrophilic interaction-reversed-phase two-dimensional liquid chromatography was evaluated by the changes of standard peptide retention. The results indicated that the better orthogonality (R2=0.34113) was achieved from the system with hydrophilic interaction columns(pH 9.3) in the first and C18columns(pH 3.3) in the second LC dimension. Coupled with multiple fraction concatenation strategy,the orthogonality of two-dimensional liquid chromatography was further evaluated in the analysis of complex rice leaf proteins. The results showed that more than 50% of the total peptides were identified less than two times, and the peptides obtained from first-dimension were well distributed across the elution window,indicating that the method showed significant orthogonality in the identification of complex rice leaf proteins. Based on the proteome discoverer software,207345 peptides belonged to 2930 protein clusters were identified.

Investigation of Evolution Rules of Phlegm and Blood Stasis Syndrome in Hyperlipidemia and Ath- erosclerosis by NMR-based Metabolic Profiling and Metabonomic Approaches / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore evolution rules of phlegm and blood stasis syndrome ( PBSS) in hyperlipidemia and atherosclerosis (AS) using NMR-based metabolic profiling and metabonomic approaches based on formulas corresponding to syndrome.</p><p><b>METHODS</b>Totally 150 SD rats were divided into the normal group, the model group, the Erchen Decoction (ED) group, the Xuefu Zhuyu Decoction (XZD) group, the Lipitor group, 30 in each group. The hyperlipidemia and AS rat model was duplicated by suturing carotid artery, injecting vitamin D3, and feeding with high fat diet. ED and XZD were used as drug probes. Blood samples were withdrawn at week 2, 4, and 8 after modeling. Blood lipids, blood rheology, histopathology and metabolomics were detected and analyzed. Results Results of blood lipids and pathology showed hyperlipidemia and early AS rat models were successfully established. At week 2 after modeling, levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) significantly increased, which reached the peak at week 4 and maintained at higher levels at week 8. ED exerted obvious effect in improving TC and LDL-C levels of early models, while XZD could greatly improve levels of TC and LDL-C of late models. Rheological results showed at week 2, there was no significant difference in whole blood viscosity, plasma viscosity, or hematocrit between the model group and the normal group (P > 0.05). At week 4 partial hemorheological indicators (such as plasma viscosity) were abnormal. Till week 8 whole blood viscosity, plasma viscosity, and hematocrit were significantly abnormal (P <0. 05, P < 0.01). As time went by, whole blood viscosity, plasma viscosity, and hematocrit showed gradual increasing tendency in the ED group, while they showed gradual decreasing tendency in the XZD group. Results of metabonomics showed significant difference in spectra of metabolites between the normal group and the model group. As modeling time was prolonged, contents of acetyl glucoprotein and glucose in the model group increased in late stage, which was in. line with results of blood lipids and hemorheology. ED showed more obvious effect in early and mid-term modeling (at week 2 and 4), and increased contents of partial metabolites (such as choline, phosphatidyl choline, glycerophosphocholine), but these changes in the XZD group were consistent with those of the model group. In late modeling (at week 8) XZD showed more obvious effect in improving contents of lactic acid, acetyl glycoprotein, LDL, creatine, choline, and glucose.</p><p><b>CONCLUSIONS</b>ED and XZD not only showed regulatory effects on lipid disorders, but also could improve dysbolism of Chos. In formulas corresponding to syndrome, damp-phlegm was main pathogenesis of hyperlipidema and AS in early and mid stages. Blood stasis syndrome began to occur along with it progressed. Phlegm can result in blood stasis and intermingles with stasis. Phlegm turbidity runs through the whole process.</p>

Effects of polysaccharides from six different dendrobium species against alcohol-induced subacute liver injury in mice / 中国药学杂志

OBJECTIVE: To investigate and compare the hepatoprotective effects of six different polysaccharides from Dendrobium huoshanense (DHP), D. officinale (DOP'), D. fimbriatum (DFP), D. chrysotoxum (DCP), D. nobile (DNF) and D. moniliforme (DMP) against alcohol-induced subacute liver injury in mice. METHODS: The mice were randomized into the normal control, alcohol control, positive control and Dendrobium treatment groups. Dendrobium treatment groups were divided into different sub-groups, which were intragastrically administered with high(200 mg · kg-1), middle(100 mg · kg-1) and low(50 mg · kg-1) dosages of six Dendrobium polysaccharides for 30 d, respectively. The positive control group were orally administrated with Lyceum barbarum polysaccharides (200 mg · kg-1 b. w) for 30 d. The normal control and alcohol control groups were fed with distilled water at the same volume as polysaccharide for 30 d. On the 16th day, the mice in all groups except the normal control group were intragastrically administered with alcohol(30%, V/V, 10 mL · kg-1) once a day for 14 d to induce subacute liver injury. After the last administration, the mice were fasted for 4 h and euthanized with pentobarbital solution for body weight measurement, blood sampling from abdominal aorta and liver tissue sampling. Then, serum biochemical parameters including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin (TBIL), total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol(HDL-C) were analyzed and hepatic biochemical parameters including TC, TG, alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ALDH), antioxidant enzymes (SOD, CAT, GSH-PX, GR, GST), glutathione(GSH) and malondialdehyde(MDA) were determined. Meanwhile, the histopathological changes in liver tissues were observed and the mRNA expression of hepatic CYP2E1, TNF-α and IL-1β in mice were measured. RESULTS: Compared with the alcohol control group, different polysaccharides from six Dendrobium species showed different hepatoprotective effects against alcohol-induced liver injury. Among all tested polysaccharides, DHP and DOP possessed the highest potential for protecting the liver from hepatotoxicity caused by alcohol intake, which was evidenced by the decreased levels of ALT, AST, ALP, TBIL, TC, TG and LDL-C in serum and TC, TG, MDA, CYP2E1, TNF-α and IL-1β in hepatic tissues, the increased levels of HDL-C in serum and SOD, CAT, GSH-PX, GR, GST, GSH, ADH and ALDH in hepatic tissues, and the ameliorated histopathological changes of hepatic tissues. CONCLUSION: DHP and DOP can protect against hepatotoxicity caused by alcohol intake in mice by inhibition of hepatic oxidative damage and inflammatory damage. The differences of hepatoprotective effects between different Dendrobium polysaccharides might be related to their differences in chemical structures including molecular weight, monosaccharide compositions and glycosidic linkages.
