ABSTRACT
We investigated the ability of Dracocephalum moldavica (EPDM) flavonoids to protect human brain microvascular endothelial cells (HBMECs) from necroptosis induced by ischemia-reperfusion injury. To mimic the process of cerebral ischemia-reperfusion injury, a necroptosis model was established by treatment with the pan-cysteine aspartic acid protease (caspase) inhibitor Z-VAD-FMK combined with oxygen-glucose deprivation/re-oxygenation (OGD/R) injury using HBMECs. Cell proliferation and cytotoxicity (cell counting kit-8, CCK-8) was used to measure cell viability. A Hoechst33342/PI fluorescent double-staining method was exploited to determine the rate of cell necroptosis. A commercial kit was used to detect lactate dehydrogenase in the cell culture supernate. DCFH-DA probes, calcein AM and JC-1 probes were used to measure changes in ROS production, mitochondrial membrane permeability transformation pore (MPTP) opening and mitochondrial membrane potential (MMP), respectively. Enzyme-linked immunosorbent assay (ELISA) kits were chosen to detect the release of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6). Western blotting was used to detect necroptosis-related proteins. The results show that relative to control group, Z-VAD-FMK combined with OGD/R injury reduced cell viability, increased the necroptosis rate and the levels of LDH and ROS in HBMECs. The MPTP of the model group cells opened and the MMP reduced. TNF-α, IL-1β, and IL-6 levels were significantly elevated. Furthermore, the expression of receptor-interacting protein kinase 3 (RIP3) and mitochondrial phosphoglycerate mutase 5 (PGAM5) was significantly increased, accompanied by an increase of phosphorylated mixed-lineage kinase domain-like protein (p-MLKL)/MLKL. EPDM partially reversed the changes of the above-mentioned factors in HBMECs induced by Z-VAD-FMK plus OGD/R injury. These results indicate that EPDM may protect HBMECs from cerebral ischemia-reperfusion injury by inhibiting the RIP3/MLKL/PGAM5 pathway and MPTP opening to maintain mitochondrial function, thereby providing a scientific basis for the use of EPDM in the treatment of cerebral ischemia-related diseases.
ABSTRACT
Objective: To investigate the pharmacokinetic and pharmacodynamic changes of Yangyin Tongnao Granules (YTG) in cerebral ischemia reperfusion rats after the compatibility of main effective parts (total alkaloids, total flavonoids, total saponins and total phenolic acids). Methods: By using the orthogonal design to research the main effective parts of YTG, nine different dosage ratios combinations were formed, which were used for oral administration in cerebral ischemia reperfusion rats. High performance liquid chromatography-diode array detector (HPLC-DAD) was used to determine the concentration of puerarin, ferulic acid, and ligustrazine in rat plasma at different time points. The non-compartmental model was used to fit the pharmacokinetic parameters by Drug and Statistics (DAS) 3.2.6 software. The total quantum statistical moment analysis method and comprehensive evaluation method were used to evaluate the total pharmacokinetic characteristics. Meanwhile, the content of superoxide dismutase (SOD) and catalase (CAT) were determined by enzyme-linked immunosorbent assay (ELISA) kits. Finally, the PK-PD model and the quantitative equations between drug concentration and efficacy were obtained. Results: The pharmacokinetic characteristics of puerarin, ferulic acid and ligustrazine in cerebral ischemia-reperfusion rats were different. Total statistical moment and comprehensive score study showed that different combinations had different effects on ACUT, mean retention time (MRT), and comprehensive evaluation. The effective parts inhibited the reduction of oxidation indexes such as SOD and CAT. Sigmoid-Emax models were adopted in all PK-PD models, and the fitting results had a good correlation with the measured data. The R values were more than 0.85. Conclusion: Compatibility of YTG activity parts had a certain effect on their pharmacokinetic behaviors and antioxidation in model rats. The total quantum statistical moment analysis and comprehensive evaluation method can be used to study the pharmacokinetics of multi-component traditional Chinese medicine prescriptions. PK-PD model could be used to predict and evaluate the correlation between pharmacokinetics and pharmacodynamics of traditional Chinese medicine prescriptions.
ABSTRACT
Objective:To explore the effect of different effective parts of Taohe Chengqitang on the synthesis and degradation of extracellular matrix in human kideny-2（HK-2） cells induced by transforming growth factor-β1（TGF-β1）. Method:Petroleum ether extract, ethyl acetate extract, n-butanol extract, raffinate and polysaccharide extract, mirabilite extract were extracted with 70% ethanol by systematic solvent method. The HK-2 cell fibrosis model induced by TGF-β1 was built to intervene the cells in different parts of Taohe Chengqitang with different concentrations (0, 50, 100, 200, 400, 800 mg·L-1). Enzyme-linked immunosorbent assay（ELISA）kit assay was used to detect collagen（Col）-Ⅰα1 and fibronectin （FN）in supernatant to screen out the main active parts. Cell counting kit-8 （CCK-8）method was used to determine the best concentration of intervention site of bioactive components. Western blot analysis was used to detect the expression levels of Col-Ⅰ, Col-Ⅲ, matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase inhibitor2 (TIMP2), and connective tissue growth factor (CTGF). Immunofluorescence assay was used to detect the expression of α-smooth muscle actin（α-SMA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） analysis was used to detect the mRNA expression of plasminogen activator inhibitor-1（PAI-1）. Result:ELISA kit assay demonstrated that compared with the model group, ethyl acetate extract, n-butanol extract and chloroform extract significantly reduced the Col-Ⅰα1 and FN content at the concentrations of 200 and 400 mg·L-1 (P<0.05, P<0.01). CCK-8 assay showed that the cells viability was significantly inhibited with drug intervention at the concentrations of 400 and 800 mg·L-1 (P<0.01). Western blot demonstrated that compared with the model group, ethyl acetate extract, n-butanol extract and chloroform extract decreased the expression levels of Col-Ⅰ, Col-Ⅲ, TIMP2 and CTGF in HK-2 cells induced by TGF-β1, and increased the expression of MMP-2 (P<0.05), with more significant effect in n-butanol extract (P<0.01). The results of immunofluorescence showed that ethyl acetate extract, n-butanol extract and chloroform extract could inhibit the expression of α-SMA (P<0.05), with more significant effect in n-butanol extract (P<0.01). The results of Real-time PCR showed that ethyl acetate extract and chloroform extract inhibited mRNA expression of PAI-1 (P<0.05), with more significant effect in n-butanol extract (P<0.01). Conclusion:The extracts of ethyl acetate, n-butanol and chloroform are the active parts of Taohe Chengqitang with the anti-renal fibrosis effect, with n-butanol extract as the most active part. The mechanism on anti-renal fibrosis may be related to its regulation of extracellular matrix (ECM) synthesis and degradation.

ABSTRACT
"Chinese materia medica component" is one of the core concepts involved in the study of component-based Chinese medicine. The difference and connection among concepts of "Chinese materia medica component", "active ingredients", "active parts", and "extracts" are the first issue to be solved in the study of component-based Chinese medicine. According to the literature about Chinese materia medica components from 1999 to 2017, we try to define its concept. Chinese materia medica component is the basic unit of component compatibility, which comes from the effective part (s), and it is a group of components with high homogeneity or a certain proportion of the composition. Its chemical composition can be identified, and the proportion of each component is relatively fixed, and its activity is generally characterized and repeatable. Chinese materia medica components, active ingredients, effective parts, and extracts are all different forms of describing the efficacy substances of traditional Chinese medicines. The difference and connection between Chinese materia medica components and related concepts were also discussed. Hence, we hope that the results of this study may provide a reference for the researchers and experts in order to promote the further development of component-based Chinese medicine.

ABSTRACT
This article was aimed to study immunomodulatory effect of chemical split fractions ofMori Cortex, in order to initially explain effective parts that played a role in immunomodulatory effect ofMori Cortex. The carbon clearance test, serum hemolysin test, E-rosette test, and lymphocyte transformation test were carried out to explore influence of these chemical split fractions ofMori Cortex on immune organs, nonspecific immunity, humoral immunity and cellular immunity. The results showed that in the carbon clearance test, 50% ethanol fraction markedly reduced the thymus index (P<0.01) and the correction indexα (P<0.05). In hemolysin test, the half value hemolysis (HC50) was improved by 30% ethanol fraction and fatty oil fraction (P<0.05). Besides, in the E-rosette test, the E-rosette ration was increased in the 30% ethanol fraction group (P<0.05). In the lymphocyte transformation test, the 30% ethanol fraction can promote the thymus and spleen lymphocytes proliferation (P<0.05 orP<0.01), while the 50% ethanol fraction inhibited the proliferation (P<0.05 orP<0.01). It was concluded that the 30% ethanol fraction can boost both the humoral immunity and cellular immunity; the 50% ethanol fraction can induce the growth of thymus with a suppressive effect on nonspecific immunity and cellular immunity; the fatty oil fraction can improve humoral immunity.
ABSTRACT
This study was aimed to explore the effect of total flavonoids and saponins from Huang-Qi Ge-Gen (HQGG) decoction on blood glucose (BG), serum lipid, interleukin-12 (IL-12) and interleukin-15 (IL-15) of liver in diabetes mellitus (DM) rats, in order to investigate their interactions in regulating DM processes. A total of 66 SD rats were randomly divided into 6 groups, which were the normal group, model group (A1B1), control group, total flavonoids group (A2B1), total saponins group (A1B2), and total flavonoids and saponins group (A2B2), with 11 rats in each group. Except the normal group, other groups were intraperitoneal injected with streptozotocin (STZ). And the experiment was according to 2×2 factorial design experiment scheme. The BG was determined before STZ injection and 7 days after the STZ injection. After 30 days, BG, serum lipid, IL-12 and IL-15 of liver were tested. Related indexes were calculated to the weighted composite score. Main and interactive effect of total flavonoids and saponins were studied according to the factorial design experiment scheme. The results showed that compared with the normal group, all indexes of model group showed statistical differences (P<0.05). Total flavonoids and saponins from HQGG decoction can effectively reduce BG, without any interactions between them. Both the total flavonoids and total saponins can reduce serum cholesterol (CHO), triglyceride (TG), liver IL-12 and IL-15. And there were interactive effects. The single use of herb achieved better effects than the combination. It was concluded that total flavonoids and saponins from HQGG decoction can reduce BG, CHO, TG, and liver IL-12 and IL-15 levels in rats. However, the regulation of total flavonoids and saponins on indexes mentioned above showed no additive effect.
