Aconiti alkaloids, mainly including monoester-diterpenoidaconitines(MDAs) and diester-diterpenoidaconitines(DDAs), are considered to act as both bioactive and toxic constituents. In the present study, a feasible, economical, and accurate HPLC method for simultaneous determination of six alkaloid markers using the Single Standard for Determination of Multi-Components(SSDMC) method was developed and fully validated. Benzoylmesaconine was used as the unique reference standard. This method was proven as accurate(recovery varying between 97.5%-101.8%, RSD < 3%), precise(RSD 0.63%-2.05%), and linear(R > 0.999 9) over the concentration ranges, and subsequently applied to quantitative evaluation of 62 batches of samples, among which 45 batches were from good manufacturing practice(GMP) facilities and 17 batches from the drug market. The contents were then analyzed by principal component analysis(PCA) and homogeneity test. The present study provided valuable information for improving the quality standard of Aconiti Lateralis Radix Praeparata. The developed method also has the potential in analysis of other Aconitum species, such as Aconitum carmichaelii(prepared parent root) and Aconitum kusnezoffii(prepared root).展开更多

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.展开更多

Abstract: 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 (...Abstract: 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.展开更多

The objective of this study was to further evaluate the effect of EFS on protection of anterior horn motoneurons and their target musculature after SCI and its mechanism. Rats were randomized into three equal groups. The EFS group received EFS for 30 minutes immediately after injury at T_(10). SCI group rats were only subjected to SCI and sham group rats were only subjected to laminectomy. Luxol fast blue staining demonstrated that spinal cord tissue in the injury center was better protected; cross-sectional area and perimeter of injured tissue were significantly smaller in the EFS group than in the SCI group. Immunofluorescence and transmission electron microscopy showed that the number of spinal cord anterior horn motoneurons was greater and the number of abnormal neurons reduced in the EFS group compared with the SCI group. Wet weight and cross-sectional area of vastus lateralis muscles were smaller in the SCI group to in the sham group. However, EFS improved muscle atrophy and behavioral examination showed that EFS significantly increased the angle in the inclined plane test and Tarlov's motor grading score. The above results confirm that early EFS can effectively impede spinal cord anterior horn motoneuron loss, promote motor function recovery and reduce muscle atrophy in rats after SCI.展开更多

文摘A better understanding of genetic bases of growth regulation is essential for bivalve breeding,which is helpful to improve the yield of the commercially important bivalves.While previous studies have identified some candidate genes accounting for variation in growth-related traits through genotype-phenotype association analyses,seldom of them have verified the functions of these putative,growth-related genes beyond the genomic level due to the difficulty of culturing commercial bivalves under laboratory conditions.Fortunately,dwarf surf clam Mulinia lateralis can serve as a model organism for studying marine bivalves given its short generation time,the feasibility of being grown under experimental conditions and the availability of genetic and biological information.Using dwarf surf clam as a model bivalve,we characterize E2F3,a gene that has been found to account for variation in growth in scallops by a previous genome-wide association study,and verify its function in growth regulation through RNA interference(RNAi)experiments.For the first time,E2F3 in dwarf surf clam,which is termed as MulE2F3,is characterized.The results reveal that dwarf surf clams with MulE2F3 knocked down exhibit a reduction in both shell size and soft-tissue weight,indicating the functions of MulE2F3 in positively regulating bivalve growth.More importantly,we demonstrate how dwarf surf clam can be used as a model organism to investigate gene functions in commercial bivalves,shedding light on genetic causes for variation in growth to enhance the efficiency of bivalve farming.
文摘The compatibility of Chinese herbs is the focus and the difficulty in traditional Chinese medicine research,and it has an important guiding role for clinical medicine.Some scholars believe that the Fuzi(Radix Aconiti Lateralis Preparata,FZ)compatibility with Tubeimu(Rhizoma Bolbostemmatis,TBM)/Gualou(Trichosanthes kirilowii Maxim,GL)does not meet the Chinese medicine theory of“eighteen incompatibilities”.However,this combination has been used many times in many clinical medications.This study reviewed the research progress of pharmacological effects of FZ,and FZ compatibility with TBM/GL,in order to correctly understand and apply the“eighteen incompatibilities”drugs,and provide a reference for further exploration of the combined application in clinical treatment.

文摘Aconiti Lateralis Radix Praeparata(Fuzi) is a commonly used traditional Chinese medicine in clinic for its potency in restoring yang and rescuing from collapse. Aconiti alkaloids, mainly including monoester-diterpenoidaconitines(MDAs) and diester-diterpenoidaconitines(DDAs), are considered to act as both bioactive and toxic constituents. In the present study, a feasible, economical, and accurate HPLC method for simultaneous determination of six alkaloid markers using the Single Standard for Determination of Multi-Components(SSDMC) method was developed and fully validated. Benzoylmesaconine was used as the unique reference standard. This method was proven as accurate(recovery varying between 97.5%-101.8%, RSD < 3%), precise(RSD 0.63%-2.05%), and linear(R > 0.999 9) over the concentration ranges, and subsequently applied to quantitative evaluation of 62 batches of samples, among which 45 batches were from good manufacturing practice(GMP) facilities and 17 batches from the drug market. The contents were then analyzed by principal component analysis(PCA) and homogeneity test. The present study provided valuable information for improving the quality standard of Aconiti Lateralis Radix Praeparata. The developed method also has the potential in analysis of other Aconitum species, such as Aconitum carmichaelii(prepared parent root) and Aconitum kusnezoffii(prepared root).

文摘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.

文摘OBJECTIVE:To elucidate the protective effects of Renshen(Radix Ginseng)and Fuzi(Radix Aconiti Lateralis Preparata)on myocardial infarction(MI)through regulating myocardial autophagy.METHODS:Thirty-one male Sprague-Dawley rats were randomized into five groups(n=6 or 7 for each).After treatment for 3 weeks,electrocardiogram(ECG)and cardiac function were recorded.Hematoxylin and eosin(HE)staining was used to detect pathological changes in the heart.Enzyme-linked immunosorbent assay(ELISA)was used to detect serum B-type brain natriuretic peptide(BNP),cardiac troponin T(c Tn T),tumor necrosis factor-α(TNF-α),and serum inflammatory cytokines.Metabolomic analysis was used to identify differential biomarkers of MI in rats.Immunohistochemistry and western blotting were used to detect BNP,cTnT,TNF-α,LC3B,Beclin-1,p62,and adenosine monophosphate activated protein kinase(AMPK)expression in cardiac tissue.RESULTS:Fuzi(Radix Aconiti Lateralis Preparata)alone or Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)markedly ameliorated cardiac dysfunction and abnormal ECGs,demonstrated by decreases in the heart weight/body weight ratio,BNP,and c Tn T.Pro-inflammation cytokine interleukin(IL)-1αsignificantly decreased and anti-inflammatory cytokine IL-10 significantly increased in Renshen(Radix Ginseng)single or Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)groups compared with the control group.HE results suggested that co-treatment produced a greater reduction in cardiomyocyte cross-sectional area than Renshen(Radix Ginseng)or Fuzi(Radix Aconiti Lateralis Preparata)alone.Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)reversed these changes to different degrees in MI rats.Furthermore,Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)down-regulated LC3 B,Beclin-1,and AMPK expression in cardiac tissue and upregulated p62 expression.CONCLUSIONS:Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)may have a greater effect on heart injury induced by MI in rats than Fuzi(Radix Aconiti Lateralis Preparata)treatment alone,and the underlying mechanism may be associated with the regulation of myocardial autophagy and anti-inflammation effects.These results provide fresh insight into the mechanism of co-treatment with Renshen(Radix Ginseng)and Fuzi(Radix Aconiti Lateralis Preparata)for MI.
文摘Abstract: 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.

文摘OBJECTIVE:To investigate the relationship between the cardiotonic activity of Fuzi(Radix Aconiti Lateralis Preparata,RALP)and its fingerprint determined by liquid chromatography-mass spectrometry(LC-MS).METHODS:First,the fingerprints of six processed products of RALP were established by high performance liquid chromatography quadrupole time-of-flight mass spectrometry(HPLC-Q-TOF-MS)followed by analysis of the principal component of the relative peak area of its common peaks.Next,the scores of the first five principal components were used as input for an artificial neural network(ANN).Additionally,the therapeutic effect of RALP was assessed by measuring the hemodynamic indexes of heart failure model rats.Subsequently,fluorescence semi-quantitative polymerase chain reaction and an enzyme-linked immunosorbent assay kit were used to determine the effects of RALP-processed products on the serum levels of noradrenaline(NA),angiotensin-Ⅰ(Ang-Ⅰ),and the expression ofβ-norepinephrine receptor m RNA(β-NRm)in the rat cardiac tissues.P<0.05 was used as the output of the ANN.Finally,a network was constructed to display the relationship between the LC-MS fingerprints and the cardiotonic activity of the RALP-processed products.RESULTS:Several types of RALPs can improve diastolic function,systolic function and heart rate.On the basis of the findings from the principal component analysis(PCA)of 16 common peaks of fingerprints of six RALP-processed products,it was revealed that the first five principal components may include 100%of the information of the original data.As observed from the multilayer perceptron neural network analysis,principal component 4 presented with the strongest effects on serum levels of NA and Ang-Ⅰin rats,while principal component1 exerted the greatest effect onβ-NRm expression in cardiac tissue.CONCLUSION:The key findings obtained from this study indicated that the network constructed by the PCA-ANN may predict pharmacodynamic effects of the main ingredients of Traditional Chinese Medicine(TCM).This method may serve as a new approach to identify the relationship between LC-MS fingerprints and the pharmacodynamic effects of TCM ingredients.

文摘Our previous study revealed that early application of electrical field stimulation(EFS) with the anode at the lesion and the cathode distal to the lesion reduced injury potential, inhibited secondary injury and was neuroprotective in the dorsal corticospinal tract after spinal cord injury(SCI). The objective of this study was to further evaluate the effect of EFS on protection of anterior horn motoneurons and their target musculature after SCI and its mechanism. Rats were randomized into three equal groups. The EFS group received EFS for 30 minutes immediately after injury at T_(10). SCI group rats were only subjected to SCI and sham group rats were only subjected to laminectomy. Luxol fast blue staining demonstrated that spinal cord tissue in the injury center was better protected; cross-sectional area and perimeter of injured tissue were significantly smaller in the EFS group than in the SCI group. Immunofluorescence and transmission electron microscopy showed that the number of spinal cord anterior horn motoneurons was greater and the number of abnormal neurons reduced in the EFS group compared with the SCI group. Wet weight and cross-sectional area of vastus lateralis muscles were smaller in the SCI group to in the sham group. However, EFS improved muscle atrophy and behavioral examination showed that EFS significantly increased the angle in the inclined plane test and Tarlov's motor grading score. The above results confirm that early EFS can effectively impede spinal cord anterior horn motoneuron loss, promote motor function recovery and reduce muscle atrophy in rats after SCI.

文摘BACKGROUND Fuzi(Radix aconiti lateralis)-Gancao(Radix glycyrrhizae)is one of the most classical drug pairs of traditional Chinese medicine.In clinical practice,decoctions containing Fuzi-Gancao(F-G)are often used in the treatment of liver diseases such as hepatitis and liver failure.AIM To investigate the metabolomics of F-G in CCl4 induced acute liver injury in rats and its regulatory effect on the bile acid profile.METHODS The pharmacodynamic effect of F-G on CCl4 induced acute liver injury in rats was evaluated,and an ultra performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)method for the simultaneous determination of 92 metabolites from multiple pathways was established to explore the protective metabolic mechanism of F-G in serum on the liver.RESULTS Twenty-four differential metabolites were identified in serum samples.The primary bile acid biosynthetic metabolic pathway was the major common pathway in the model group and F-G group.Subsequently,a UPLC-MS/MS method for simultaneous determination of 11 bile acids,including cholic acid,ursodeoxycholic acid,glycochenodeoxycholic acid,glycochenodeoxycholic acid,taurocholic acid,glycocholic acid,chenodeoxycholic acid,deoxycholic acid,taurochenodeoxycholic acid,taurocholic acid,and glycinic acid,was established to analyze the regulatory mechanism of F-G in serum.F-G decreased the contents of these 11 bile acids in serum in a dose-dependent manner compared with those in the model control group.CONCLUSION F-G could protect hepatocytes by promoting the binding of free bile acids to glycine and taurine,and reducing the accumulation of free bile acids in the liver.F-G could also regulate the compensatory degree of taurine,decreasing the content of taurine-conjugated bile acids to protect hepatocytes.
