OBJECTIVE: Aconite is a traditional Chinese herbal medicine that has been found to inhibit the development of liver cancer; however, its exact molecular mechanisms in this process remain unclear. This study explores how aconite aqueous extract (AAE) inhibits hepatocellular carcinoma (HCC). METHODS: An in vivo mouse model of subcutaneous liver cancer was established. After AAE treatment, immunohistochemistry (IHC) was used to determine the effect of AAE on natural killer (NK) cells. Subsequently, C57BL/6 mice were used to establish the subcutaneous tumor model, and a group of these mice were treated with anti-PK163 antibody to remove NK cells, which was verified by flow cytometry and IHC. The effect of AAE on the proliferation of HCC cells in vitro was determined using cell counting kit-8. The effect of AAE on chemokine production in HCC cells was measured using real-time quantitative polymerase chain reaction and an enzyme-linked immunosorbent assay. The effect of AAE on the migration of NK cells was determined using a transwell assay. Finally, the molecular mechanism was investigated using the Western blotting method. RESULTS: We demonstrated that the ability of AAE to induce overexpression of the cytokine C-C motif chemokine ligand 2 (CCL2) in HCC cells is fundamental to the infiltration of NK cells into the tumor bed. Mechanistically, we found that the upregulation of CCL2 was achieved by the activation of c-Jun N-terminal kinase but not extracellular regulated protein kinase or p38. CONCLUSION Our findings suggest that AAE can be used as an effective immune adjuvant to enhance antitumor immunity by increasing NK cell infiltration into tumors, which could help to improve the efficacy of HCC treatments.

This study selected three typical Chinese herbs with cold property(Rhei Radix et Rhizoma, Scutellariae Radix, and Coptidis Rhizoma) and another three with heat property(Cinnamomi Cortex, Zingiberris Rhizoma, and Aconiti Lateralis Radix Praeparata) to observe their regulatory effects on metabolism in animal organism, especially on lipid and energy metabolism in mice after a short-(7 d) and long-term(35 d) intervention. The mRNA expression levels of lipid metabolism genes in epididymal adipose tissue and liver were determined by real-time PCR. The oxygen consumption, carbon dioxide production, and energy consumption were detected by metabolic system. After the short-term intervention, the Chinese herbs with heat property significantly reduced epididymal adipose tissue index and elevated the expression levels of acetyl-CoA carboxylase(ACC), lipoprotein lipase(LPL), and carnitine-palmityl transferase 1(CPT-1) in liver and epididymal adipose tissues. However, those with cold property promoted the expression of above-mentioned genes in epididymal adipose tissue. After the long-term intervention, cold and heat Chinese herbs had no significant effect on epididymal adipose tissue index of animals, while cold Chinese herbs could increase carbon dioxide production and energy consumption and reduce activity. These findings demonstrated that the short-term intervention effects of cold and heat Chinese herbs on animal metabolism were significantly stronger than the long-term intervention effects. Specifically, the short-term intervention with cold Chinese herbs enhanced the lipid metabolism in epididymal adipose tissue, while the heat Chinese herbs promoted lipid metabolism in epididymal adipose tissue and liver. The long-term intervention with cold and heat Chinese herbs resulted in no obvious change in lipid level, but long-term intervention with cold Chinese herbs accelerated energy consumption of the body. This study preliminarily observed the effects of cold and heat Chinese herbs on normal animal physiology from lipid and energy metabolism, which would provide reference for explaining the biological basis of Chinese herbs with cold or heat property based on biological response.

This study aims to investigate the therapeutic effects of alkaloids in Tibetan medicine Bangna(Aconiti Penduli et Aconiti Flavi Radix) on osteoarthritis(OA) rats in vitro and in vivo and the underlying mechanisms. Chondrocytes were isolated from 2-3 week-old male SD rats and lipopolysaccharide(LPS) was used to induce OA in chondrocytes in vitro. Methyl thiazolyl tetrazolium(MTT) assay was used to investigate the toxicity of seven alkaloids(12-epi-napelline, songorine, benzoylaconine, aconitine, 3-acetylaconitine, mesaconitine, and benzoylmesaconine) to chondrocytes. Chondrocytes were classified into the control group, model group(induced by LPS 5 μg·mL~(-1) for 12 h), and administration groups(induced by LPS 5 μg·mL~(-1) for 12 h and incubated for 24 h). The protein expression of inflammatory factors cyclooxygenase-2(COX-2), inducible nitric oxide synthetase(iNOS), tumor necrosis factor-α(TNF-α), and interleukin-1β(IL-1β) in each group were detected by Western blot, and the protein expression of matrix metalloprotease-13(MMP-13), aggrecan, collagen Ⅱ, fibroblast growth factor 2(FGF2) by immunofluorescence staining. For the in vivo experiment, sodium iodoacetate was used to induce OA in rats, and the expression of MMP-13, TNF-α, and FGF2 in cartilage tissues of rats in each group was detected by immunohistochemistry. The results showed that the viability of chondrocytes could reach more than 90% under the treatment of the seven alkaloids in a certain dose range. Aconitine, 12-epi-napelline, songorine, 3-acetylaconitine, and mesaconitine could decrease the protein expression of inflammatory factors COX-2, iNOS, TNF-α and IL-1β compared with the model group. Moreover, 12-epi-napelline, aconitine, and mesaconitine could down-regulate the expression of MMP-13 and up-regulate the expression of aggrecan and collagen Ⅱ. In addition, compared with the model group and other Bangna alkaloids, 12-epi-napelline significantly up-regulated the expression of FGF2. Therefore, 12-epi-napelline was selected for the animal experiment in vivo. Immunohistochemistry results showed that 12-epi-napelline could significantly reduce the expression of MMP-13 and TNF-α in cartilage tissues, and up-regulate the expression of FGF2 compared with the model group. In conclusion, among the seven Bangna alkaloids, 12-epi-napelline can promote the repair of OA in rats by down-regulating the expression of MMP-13 and TNF-α and up-regulating the expression of FGF2.

The chemical constituents from the roots of Aconitum kongboense were studied. Twenty-five diterpenoid alkaloids were isolated from the 95% methanol extract of the roots of A. kongboense by silica gel, reverse-phase silica gel and basic alumina column chromatography. They included a new aconitine-type diterpenoid alkaloid, named as kongboensenine(1), and twenty-four known ones(2-25), i.e., acotarine F(2), acotarine G(3), 14-acetyltalatisamine(4), talatisamine(5), indaconitine(6), yunaconitine(7), chasmanine(8), 6-epi-foresticine(9), homochasmanine(10), 8-deacetyl-yunaconitine(11), chasmaconitine(12), ajaconine(13), franchetine(14), ezochasmanine(15), crassicautine(16), 14-O-deacylcrassicausine(17), genicunine A(18), falconeridine(19), sachaconitine(20), liljestrandisine(21), 8-methyl-14-acetyltalatisamine(22), kongboendine(23), 14-benzoylchasmanine(24) and pseudaconine(25). Their structures were elucidated by common spectroscopic methods including high-resolution electrospray ionization mass spectrometry(HR-ESI-MS) and nuclear magnetic resonance(NMR) techniques. Compounds 2-4, 10, 13, 15-19 and 21-22 were isolated from this plant for the first time. Experimental results showed that all compounds did not have a significant inhibitory activity against acetylcholinesterase(AChE).

In this study,transcriptomics technique was used to investigate the mechanism of action of Aconiti Lateralis Radix Praeparata on acute heart failure rats induced by propafenone hydrochloride.First,rats were randomly divided into normal group,model group and administration group(1.25,2.5,5 g·kg-1).A rat with acute heart failure was constructed by intravenous femoral administration of proparone hydrochloride.The changes of heart rate,+dp/dtmaxand-dp/dtmaxat 5,10,20,30 and 60 min were recorded.Then another group of rats were given the same drug delivery method.In another group of animals,serum TNF-α could be determined by ELISA with the same dosage method.High-throughput sequencing technology was used to detect all gene expression differences in cardiac tissue samples of rats with acute heart failure.Through functional annotation and enrichment analysis,gene expression signaling pathways of rats with acute heart failure and rats with post-administration heart failure were screened out.The results showed that heart rate and LV+dp/dtmaxand LV-dp/dtmaxwere significantly decreased in the model group(P<0.05),while heart rate and LV+dp/dtmax and LV-dp/dtmaxwere significantly increased in the drug group(P<0.05,P<0.01).Moreover,ANP,BNP and TNF-α in acute heart failure rats was significantly decreased in high-dose aconite decoction group(P<0.05).Transcriptomics analysis showed that the mechanism of action was mainly related to activation of PI3 K-AKT signaling pathway and Jak-STAT pathway.Compared with the model group,aconite decoction up-regulated the expression of phosphatidylinostol 3-kinase(PI3 K),lysophosphatidic acid(LAP3),Bcl-3 and STAT genes,and down-regulated the expression of integrin(ITGA),nuclear orphan receptor(Nur77) genes.It could be concluded that the mechanism of aconite in treating acute heart failure rats may be related to the regulation of the PI3 k-Akt/Jak-STAT pathway.

The tuberous roots of Aconitum carmichaeli are largely used in traditional Chinese medicine and widely grown in Jiangyou, Sichuan, China. During the growth process, this medicinal plant releases a large amount of allelochemicals into soil, which retard the growth and development of near and late crops. Therefore, a pure culture experiment was thus carried out by seed soaking to study the allelopathic effects of extracts from tuberous roots of A. carmichaeli (ETR) on the seed germination and young seedling growth of Lolium perenne, Trifolium repens, and Medicago sativa, the late pasture grasses after cultivation of A. carmichaeli. The results showed that three pasture grasses varied significantly in seed germination and young seedling growth in response to ETR concentrations. Seed germination of M. sativa was stimulated by low ERT concentration (0.01 x g(-1)), while all of pasture grass seeds germinated poorly in solution with 1.00 g x L(-1). Seed soaking with 1.00 g x L(-1) also inhibited significantly the growth of pasture young seedlings, with M. sativa showing the highest seedling height reduction of 42.05% in seeding height, followed by T. repens (40.21%) and L. perenne with about 11%. Cultivation of L. perenne could thus be beneficial to increase whole land productivity in A. carmichaeli-pasture grass cropping systems. In addition, hydrolysis of protein, starch, and inositol phosphates was blocked and free amino acids, soluble sugars and phosphorus were decreased in seeds by seed soaking with ETR, which could be one of the reason for the inhibition of seed germination. There was a significant reduction in root vigor, nitrate reductase, and chlorophyll after the seed treatment with ETR, indicating the suppression of nutrient uptake, nitrate assimilation, and photosynthesis by allelopathic chemicals in ETR, which could lead to the slow growth rate of pasture grass seedlings.

Chuanwu (CW), a famous traditional Chinese medicine (TCM) from the mother roots of Aconitum carmichaelii Debx.. (Ranunculaceae), has been used for the treatment of various diseases. Unfortunately, its toxicity is frequently reported because of its narrow therapeutic window. In the present study, a metabolomic method was performed to characterize the phenotypically biochemical perturbations and potential mechanisms of CW-induced toxicity. Meanwhile, the expression level of toxicity biomarkers in the urine were analyzed to evaluate the detoxification by combination with Gancao (Radix Glyeyrrhizae, CG), Baishao (Radix Paeoniae Alba, CS) and Ganjiang (Rhizoma Zingiberis, CJ), which were screened from classical TCM prescriptions. Urinary metabolomics was performed by UPLC-Q-TOF-HDMS, and the mass spectra signals of the detected metabolites were systematically analyzed using pattern recognition methods. As a result, seventeen biomarkers associated with CW toxicity were identified, which were associated with pentose and glucuronate interconversions, alanine, aspartate, and glutamate metabolism, among others. The expression levels of most toxicity biomarkers were effectively modulated towards the normal range by the compatibility drugs. It indicated that the three compatibility drugs could effectively detoxify CW. In summary, our work demonstrated that metabolomics was vitally significant to evaluation of toxicity and finding detoxification methods for TCM.

Sini decoction (SND), a classical traditional Chinese medicine emergency formula recorded in Shanghan Lun (Treatise on Febrile Diseases), which is composed of Aconiti Lateralis Preparata Radix, Glycyrrhizae Preparata Radix and Zingiberis Rhizoma. Modern clinical and pharmacological researches have shown that SND can protect the myocardium effectively during myocardial ischemia reperfusion injury (MI-RI). A myocardial ischemia reperfusion injury model of H9c2 cardiomyocytes in vitro has been established. Four groups, control group, MI-RI Model group, SND group and SND without Glycyrrhizae Radix group, were arranged. The livability, the level of LDH and CK activity in H9c2 cardiomyocytes in different groups were tested. By combining with principal components analysis (PCA), partial least squares discriminant analysis (PLS-DA), orthogonal partial least squares projection of latent structures-discriminant analysis (OPLS-DA), 17 biomarkers in extracellular fluid were identified and 15 of them were related to the pathway of biological processes. The results showed that the attenuate and synergistic mechanism between Aconiti Lateralis Praeparata Radix and Glycyrrhizae Radix for toxicity reduction was related with the glycolysis, lipid metabolism, citrate cycle and nitrogen metabolism of amino acids metabolism. The study proved the effect on H9c2 cardiomyocyte treated by MI-RI injury both SND group and SND without Glycyrrhizae Radix group, and compared with the SND without Glycyrrhizae Radix, the protective effect of myocardial ischemia reperfusion injury model of H9c2 cardiomyocyte from SND was stronger.

The paper is to report the study of the effect of Shenfu injection on the enzyme activity of liver CYP450 and its mRNA level of rat liver. Microsome of rat liver was prepared after intravenous administration of Shenfu injection for 7 days. The enzyme activity was quantified by Cocktail method. Meanwhile, the mRNA expression of CYP1A2, CYP2B1/2, CYP2C11 and CYP3A1 in the liver was detected by RT-PCR. Shenfu injection obviously induced the enzyme activities of CYP2B and CYP2C. Meantime Shenfu injection decreased the enzyme activities of CYP1A2 and CYP3A. The mRNA levels of CYP2B and CYP2C were also induced in rats treated with Shenfu injection. But it obviously inhibited the mRNA level of CYP1A2 and CYP3A. Since the enzyme activity and mRNA level were obviously changed after administration, the potential effect of drug-drug interaction should be concerned.
