Study on Hot Property of Aconiti Lateralis Radix Praeparata and Its Compatibility with Zingiberis Rhizoma Based on Animal Temperature Tropism

Objective To establish an objective method for evaluating the intrinsic characteristics between hot and cold properties of herbal drugs and to study the hot property of Aconiti Lateralis Radix Praeparata(ALRP) and its compatibility with Zingiberis Rhizoma(ZR) on animal temperature tropism.Methods The equipment with cold/hot pads was used to investigate the variety of temperature tropism among mice treated by ALRP and its compatibility with ZR.Meanwhile,the activities of adenosine triphosphatase(ATPase),total anti-oxidant capability(T-AOC),and total superoxide dismutase(T-SOD) were measured.Results Compared with the homologous ALRP group,the compatibility between ALRP and ZR(AZ) had a stronger action against the decreasing of remaining rate on hot pad(P < 0.05),suggesting an enhancement of cold tropism.Meanwhile,the internal indexes of Na+-K+-ATPase activity,Ca2+-Mg2+-ATPase activity,and oxygen consuming volume increased significantly(P < 0.05),suggesting an enhancement of energy metabolism.The changes of T-AOC and T-SOD activity suggested that AZ reinforced the anti-oxidative capability of mice.In addition,it could be inferred from cluster analysis that the activity of AZ was concretely stronger than that of homologous ALRP.Conclusion ALRP and ZR are both herbs with hot property,but AZ has an enhanced trend of hot property.This external behavior of cold tropism and the internal activity of energy metabolism and anti-oxidant might reflect the internal hot property in an intuitive and objective way.The changes of ATPase activity of liver tissue might be the mechanism of drug action.

Huanglian decoction suppresses the growth of hepatocellular carcinoma cells by reducing CCNB1 expression

BACKGROUND Hepatocellular carcinoma(HCC)is one of the most prevalent cancers in human populations worldwide.Huanglian decoction is one of the most important Chinese medicine formulas,with the potential to treat cancer.AIM To investigate the role and mechanism of Huanglian decoction on HCC cells.METHODS To identify differentially expressed genes(DEGs),we downloaded gene expression profile data from The Cancer Genome Atlas Liver Hepatocellular Carcinoma and Gene Expression Omnibus(GSE45436)databases.We obtained phytochemicals of the four herbs of Huanglian decoction from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform.We also established a regulatory network of DEGs and drug target genes and subsequently analyzed key genes using bioinformatics approaches.Furthermore,we conducted in vitro experiments to explore the effect of Huanglian decoction and to verify the predictions.In particular,the CCNB1 gene was knocked down to verify the primary target of this decoction.Through the identification of the expression levels of key proteins,we determined the primary mechanism of Huanglian decoction in HCC.RESULTS Based on the results of the network pharmacological analysis,we revealed 5 bioactive compounds in Huanglian decoction that act on HCC.In addition,a protein-protein interaction network analysis of the target genes of these five compounds as well as expression and prognosis analyses were performed in tumors.CCNB1 was confirmed to be the primary gene that may be highly expressed in tumors and was significantly associated with a worse prognosis.We also noted that CCNB1 may serve as an independent prognostic indicator in HCC.Moreover,in vitro experiments demonstrated that Huanglian decoction significantly inhibited the growth,migration,and invasiveness of HCC cells and induced cell apoptosis and G2/M phase arrest.Further analysis showed that the decoction may inhibit the growth of HCC cells by downregulating the CCNB1 expression level.After Huanglian decoction treatment,the expression levels of Bax,caspase 3,caspase 9,p21 and p53 in HCC cells were increased,while the expression of CDK1 and CCNB1 was significantly decreased.The p53 signaling pathway was also found to play an important role in this process.CONCLUSION Huanglian decoction has a significant inhibitory effect on HCC cells.CCNB1 is a potential therapeutic target in HCC.Further analysis showed that Huanglian decoction can inhibit HCC cell growth by downregulating the expression of CCNB1 to activate the p53 signaling pathway.

Effects of Radix Aconiti Lateralis Preparata and Rhizoma Zingiberis on Energy Metabolism and Expression of the Genes Related to Metabolism in Rats

Objective： To study the influence of Radix aconiti lateralis preparata and Rhizoma zingiberis, two species of Chinese medicinal herbs with hot property, on energy metabolism and gene expression spectrum, and to analyze the possible mechanism of their effects. Methods： Forty-eight specific pathogen free Wistar rats were randomly divided into a Radix aconiti lateralis preparata group, a Rhizoma zingiberis group, and a control group. They were intragastrically treated with concentrated decoction of Radix aconiti lateralis preparata, Rhizoma zingiberis and normal saline respectively for 20 days. Toe temperature （TT）, energy intake （El）, digestible energy （DE）, and metabolizable energy （ME） were measured. The content of adenosine triphosphate （ATP） and energy charge （EC） in hepatic tissue were measured with high performance liquid chromatography （HPLC）. The activity of ATPase and succinate dehydrogenase （SDH） in the liver were detected with chemical colorimetry. The gene expression in the liver was detected with Illumina＇s rat Ref-12 gene array. The differential expression genes were selected, annotated and classified based on Gene Ontology （GO）. Real-time quantitative reverse-transcriptase PCR （Q-RT-PCR） was used to test the accuracy of results. Results： Compared with the control group, the -I-r on the 10^th day after the beginning of administration and ATP in the Radix aconiti lateralis preparata and Rhizoma zingiberis groups increased significantly （P〈0.05）. El/body mass （BM）, DE/BM, ME/BM, the hepatic EC and the activity of Na^＋-K^＋-ATPase, Ca^2＋-Mg^2＋-ATPase and SDH of liver increased significantly only in the Radix aconiti lateralis preparata group （P〈0.05）. There were 592 differential expression genes in the Radix aconiti/ateralis preparata group and 1 159 in the Rhizoma zingiberis group compared with the control group. Among the differential expression genes, genes related to metabolic processes were the most significant based on GO analysis. There were 337 strips of gene differential expression in common in both Radix aconiti lateralis preparata and Rhizoma zingiberis groups compared with the control group. Conclusions： Herbs with hot property such as Radix aconiti lateralis preparata and Rhizoma zingiberis could improve the energy metabolism in rats, through influencing the metabolic process of sugar, lipid, and amino acid. It could also promote the production, storage, and utilization of energy by regulating the gene expression related to metabolism, which may be the main molecular mechanism of warming yang and dispelling cold for the treatment of the cold syndrome according to Chinese medicine theory.

Analysis of anti-platelet aggregation components of Rhizoma Zingiberis using chicken thrombocyte extract and high performance liquid chromatography

Background The conventional procedure for screening bioactive components from traditional Chinese medicine is time-consuming, expensive and low efficient. Therefore, some alternative strategies are needed urgently. A novel method for screening anti-platelet aggregation components from oleoresins was developed using chicken thrombocyte extract and high performance liquid chromatography. Methods The anti-platelet aggregation components of oleoresins were combined with receptors, channels and enzymes of chicken thrombocytes under physiological environment. Unbound substances were washed away and bound compounds were eluted using specific phosphate buffered solution （PBS）. Compounds released from target sites were collected and analyzed by high performance liquid chromatography and LC-MS. The activity of three compounds which were screened from this model was confirmed using platelet aggregation pharmacology in vivo. Results There were four typical compounds that bound to the thrombocytes： 6-gingerol, 8-gingerol, 6-shogaol and 10-gingerol, and all had shown anti-platelet aggregation activities. Eight-gingerol displayed the best anti-platelet aggregation effect. Conclusions Chicken thromobcyte extract can be used to isolate chemicals that are ligands of the receptor or other bio-targets on the platelet. This may therefore be a simple and efficient method to screen for anti-platelet aggregation compounds from traditional Chinese medicine.

Research on Fuzi based on animal thermotropism behavior to discover if it has fewer "hot" characteristics without Ganjiang

OBJECTIVE:To investigate whether Fuzi(Radix Aconiti Praeparata) has fewer "hot" characteristics when administered without Ganjiang(Rhizoma Zingiberis).METHODS:Differences in the thermotropism behaviors of mice treated either with Fuzi(Radix Aconiti Praeparata),Ganjiang(Rhizoma Zingiberis) or the combination of the two given intragastrically were investigated using the Animal Thermotropism Behavior Surveillance System.The water intake volume,oxygen consumption volume,adenosine triphosphatase(ATPase) activity,total antioxidant capacity(T-AOC) and total superoxide dismutase(T-SOD) activity were determined during the investigation.RESULTS:When Fuzi and Ganjiang were administered together,the rate at which mice remained on a warm plate("remaining rate") and the times and distances of their movement were all significantly reduced(P<0.05).Compared with the Normal group,the reduction was 55.1%,48.3% and 44.8%,while compared with the Fuzi group,the reduction was 57.6%,34.3% and 36.0%,indicating that "cold" tropism was significantly increased.Compared with the Normal and Fuzi groups,the ATPase activity and the respiratory oxygen consumption volume of the Fuzi + Ganjiang group were significantly increased(P<0.05),suggesting an improvement in energy metabolism and showing a "hot" characteristic when Fuzi and Ganjiang are present together.Additionally,the T-AOC and T-SOD activity were significantly enhanced(P<0.05).CONCLUSION:The behavior of mice tending toward "cold" tropism can be regarded as a quantitative reflection of Fuzi having fewer characteristics consistent w ith a "hot" nature when not used with Ganjiang,the functional mechanism of which may be a change in the ATPase activity in liver tissue.

Comprehensive Metabolic Profiling of Modified Gegen Qinlian Decoction by Ultra-high-Performance Liquid Chromatography-Diode Array Detection-Q-Exactive-Orbitrap-Electrospray Ionization-Mass Spectrometry/Mass Spectrometry and Application of High-Performance

Objective:Gegen Qinlian decoction(GQD)is a classical traditional Chinese medicine formulation which has been used for almost 2000 years.At Guang'anmen Hospital,Beijing,a modified GQD version(m GQD)with seven instead of four herbal ingredients has been applied to treat Type 2 diabetes.Quality control is a crucial prerequisite for the therapeutic application of herbal medicines.For the identification of products derived from classical GQD,the Chinese Pharmacopeia requires the analysis of only three marker compounds.Because m GQD is a more complex mixture containing seven herbs and hundreds of constituents,the pharmacopoeia method for GQD is inadequate.Materials and Methods:A more comprehensive characterization of the formula's constituents has been developed using ultra-high-performance liquid chromatography-diode array detection(UHPLC-DAD)-Q-Exactive-mass spectrometry(MS)in electrospray ionization positive and negative mode.Moreover,a new method for the fingerprint analysis of m GQD via high-performance thin-layer chromatography(HPTLC)has been established.Results:Altogether,91 compounds have been assigned to their originating plants and 84 substances were identified either by comparison with authentic references or with data from the literature.The HPTLC method is based on the application of two different mobile phases and is able to detect both lipophilic and hydrophilic constituents of m GQD.Conclusions:The modified GQD was extensively characterized by UHPLC combined with DAD and Q-Exactive Orbitrap high-resolution MS detection,leading to the assignment and identification of compounds present in the decoction.In addition,a new method for the fingerprint analysis of the m GQD using HPTLC was established,which allows fast and simple identification of the herbal ingredients in the mixture.
