Research advancement in mechanisms of processing and compatibility for detoxication of Aconitums / 中国中药杂志

Aconitums,represented by Aconite Radix,Aconiti Lateralis Radix Praeparata and Aconiti Kusnezoffh Folium,is a kind of traditional Chinese medicine with a long medicinal history in China. They possess the significant toxicity and therapeutic effects simultaneously. Their potent effects of rescuing from dying,curing rheumatism,anti-inflammation,and analgesia make Aconitums highly regarded by physicians and pharmacists of various dynasties. However,countless poisoning cases caused by an irrational use of Aconitums were reported. In case of improper application and exceeding the therapeutic window,the acute cardiotoxicity and neurotoxicity would be caused,seriously threatening health and even life of the users. Therefore,the clinical application of Aconitums is limited to some extent. To avoid its toxicity and ensure the safety of medicinal use,Aconitums is usually used in a form of its processed products instead of the crude herbs,or combined with some other traditional Chinese medicines in a normal prescription. A proper processing and compatibility method can detoxicate its severe toxicity,reduce the adverse reactions,and also significantly broaden the indications and application range of Aconitums. This provides a guarantee for the secondary exploitation and utilization of Aconitums. In this paper,the traditional processing methods of Aconitums,along with the modern advancement were reviewed,and the mechanisms of detoxification by processing and compatibility were also illuminated. The physical detoxification mode and chemical detoxification mode were found as two main detoxification ways for Aconitums. In particular,the detoxification by hydrolysis,ion-pair,and saponification were three main means. The mechanisms illustrated in this paper can be a reference to the development of modern processing method and a guidance for appropriate use of Aconitums in clinical application.

Overall Evaluation on Mutual Detoxication Mechanism of Tripterygii Radix et Rhizoma and Lysimachiae Herba by Correlation Analysis of “Chemical Composition Spectrum-attenuation Spectrum-biological Information Spectrum” / 中国实验方剂学杂志

Objective: To overall evaluate the mutual detoxication mechanism of Tripterygii Radix et Rhizoma(LGT) compatible with Lysimachiae Herba(JQC) in tumor-bearing state.Method: Twelve differentially characteristic components before and after compatibility were used as chemical composition spectrum,six indicators including serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),creatinine(Cr) and urea nitrogen(BUN),malondialdehyde(MDA) levels in the liver and kidney tissues were used as attenuation spectrum,and twelve biological indicators including glutathione(GSH),glutathione-S-transferase(GST),glutathione peroxidase(GPx),superoxide dismutase(SOD),catalase(CAT) and interleukin(IL)-10 in the liver and kidney were used as the biological information spectrum.Mutual detoxication mechanisms of LGT compatible with JQC in tumor-bearing state were overall evaluated by principal component analysis(PCA),and the contribution of chemical components and biological indicators to mutual detoxication was further evaluated by gray correlation analysis(GCA) of "chemical composition spectrum-attenuation spectrum-biological information spectrum".Result: Compared with the model group,the attenuation spectrum scores Z values of S180(Z1 value) and H22(Z3 value) increased significantly after LGT being used alone(PZ1 value and Z3 value caused by LGT when the ratio of LGT and JQC was 4:1,2:1,1:1,1:2 and 1:4(PZ values(Z1 value and Z3 value) of LGT-JQC in the mass ratios including 4:1,1:1,1:2 and 1:4 was significantly higher than that in the ratio of 2:1(PZ values of the bioinformatics scores in the S180(Z2 value) and H22(Z4 value) tumor-bearing state,these two values were significantly increased after compatibility with JQC.The chemical components contributing the most to the attenuating effect of S180 and H22 in tumor-bearing state were 3# and 10#,respectively.The most important biological indicators were kidney GPx and renal GSH.Conclusion: LGT combined with JQC in the mass ratio of 4:1-1:4 can attenuate LGT-induced subacute toxicity in S180 and H22 tumor-bearing state,and the best ratio of such effect is 2:1.The attenuating effect reflects the thought of "there is no reason why there is no meteorology".The mechanism of attenuating action involves antioxidative damage and anti-inflammatory reaction of the liver and kidney,especially the renal GPx(S180) and renal GSH(H22) as the greatest contribution to the detoxication mechanism.

Establishment of one-step approach to detoxification of hypertoxic aconite based on the evaluation of alkaloids contents and quality / 中国天然药物

Aconite is a valuable drug and also a toxic material, which can be used only after detoxification processing. Although traditional processing methods can achieve detoxification effect as desired, there are some obvious drawbacks, including a significant loss of alkaloids and poor quality consistency. It is thus necessary to develop a new detoxification approach. In the present study, we designed a novel one-step detoxification approach by quickly drying fresh-cut aconite particles. In order to evaluate the technical advantages, the contents of mesaconitine, aconitine, hypaconitine, benzoylmesaconine, benzoylaconine, benzoylhypaconine, neoline, fuziline, songorine, and talatisamine were determined using HPLC and UHPLC/Q-TOF-MS. Multivariate analysis methods, such as Clustering analysis and Principle component analysis, were applied to determine the quality differences between samples. Our results showed that traditional processes could reduce toxicity as desired, but also led to more than 85.2% alkaloids loss. However, our novel one-step method was capable of achieving virtually the same detoxification effect, with only an approximately 30% alkaloids loss. Cluster analysis and Principal component analysis analyses suggested that Shengfupian and the novel products were significantly different from various traditional products. Acute toxicity testing showed that the novel products achieved a good detoxification effect, with its maximum tolerated dose being equivalent to 20 times of adult dosage. And cardiac effect testing also showed that the activity of the novel products was stronger than that of traditional products. Moreover, particles specification greatly improved the quality consistency of the novel products, which was immensely superior to the traditional products. These results would help guide the rational optimization of aconite processing technologies, providing better drugs for clinical treatment.

UPLC/ESI-QTOF-MS-based metabolomics survey on the toxicity of triptolide and detoxication of licorice / 中国天然药物

Triptolide (TP) from Tripterygium wilfordii has been demonstrated to possess anti-inflammatory, immunosuppressive, and anticancer activities. TP is specially used for the treatment of awkward rheumatoid arthritis, but its clinical application is confined by intense side effects. It is reported that licorice can obviously reduce the toxicity of TP, but the detailed mechanisms involved have not been comprehensively investigated. The current study aimed to explore metabolomics characteristics of the toxic reaction induced by TP and the intervention effect of licorice water extraction (LWE) against such toxicity. Obtained urine samples from control, TP and TP + LWE treated rats were analyzed by UPLC/ESI-QTOF-MS. The metabolic profiles of the control and the TP group were well differentiated by the principal component analysis and orthogonal partial least squares-discriminant analysis. The toxicity of TP was demonstrated to be evolving along with the exposure time of TP. Eight potential biomarkers related to TP toxicity were successfully identified in urine samples. Furthermore, LWE treatment could attenuate the change in six of the eight identified biomarkers. Functional pathway analysis revealed that the alterations in these metabolites were associated with tryptophan, pantothenic acid, and porphyrin metabolism. Therefore, it was concluded that LWE demonstrated interventional effects on TP toxicity through regulation of tryptophan, pantothenic acid, and porphyrin metabolism pathways, which provided novel insights into the possible mechanisms of TP toxicity as well as the potential therapeutic effects of LWE against such toxicity.

Anti-tumor activity of rosmarinic acid in 7,12-dimethylbenz(a)anthracene (DMBA) induced skin carcinogenesis in Swiss albino mice.

Aim of the present study was to evaluate the anti-tumor effect of orally administered rosmarinic acid in 7,12-dimethylbenz(a)anthracene (DMBA) induced skin carcinogenesis in Swiss albino mice. Phase I and II detoxication agents, lipid peroxidation byproducts, antioxidants and apoptotic biomarkers were used to assess chemopreventive efficacy of rosmarinic acid in DMBA induced skin carcinogenesis. Skin squamous cell carcinoma was induced at the shaved back of mice by applying DMBA (20 μg in 0.1 mL acetone) twice weekly for 8 weeks. Tumor formation (100%) was observed within 15 weeks of treatment in DMBA alone. Marked alterations in the status of above mentioned biomarkers were observed in tumor bearing mice. Oral administration of rosmarinic acid completely prevented the formation of skin tumors during DMBA-induced mouse skin carcinogenesis. Also, oral administration of rosmarinic acid brought back the status of phase I and phase II detoxication agents, lipid peroxidation byproducts, antioxidants and apoptotic markers (p53, Bcl-2, caspase-3 and caspase-9) in DMBA treated mice. Results of the present study suggested that rosmarinic acid had potent anti-cancer, anti-lipid peroxidative and apoptotic effect in DMBA-induced skin carcinogenesis.

Association of MRP2 expression level and arsenic methylation in rats' liver treated with sodium arsenite and sodium arsenate / 中国地方病学杂志

Objective To explore the effect of sodium arsenite (iAs3+) and sodium hydrogen arseuate (iAs5+) exposure on rat multidrug resistance protein 2 (MRP2) expression,and the correlation of liver arsenic and its methylation products,and to provide a basis for further elucidating the mechanism of arsenic toxicity.Methods Seventy wistar rats were randomly divided into seven groups,10 rats in each group.Control group was administrated with deionized water.Sodiun arsenite high-dose group,middle-dose group,low-dose group were administrated with different concentrations of sodium arsenite:20.0,6.7 and 2.2 mg/kg BW every day,respectively.Animals were sacrificed 90 days later by cervical dislocation to collect liver,the expression of MRP2 in the membrane of hepatocyte was determined by Western blotting.HPLC-HGAFS was employed to determine the content or level of arsenic and its methylation products.Correlation between expression of MRP2 and arsenic methylation products was analyzed using Pearson's linear correlation method.Results The MRP2 protein levels of control group,iAs3+ and iAs5+ high-,middle-,low-dose groups were 1.21 ± 0.13,1.85 + 0.09,1.65 + 0.19,1.61 + 0.18,1.69 + 0.04,1.42 + 0.19,1.27 ± 0.10.Compared to control group,MRP2 protein levels of iAs3+ high-,middle-,low-dose group and iAs5+ high-dose group were increased (P ＜ 0.05); Compared with the low-dose group,MRP2 protein levels of iAs3+ and iAs5+ high dose groups were increased(P ＜ 0.05); Comparing the matched doses group of iAs5+ and iAs3+,MRP2 protein levels of iAs3+ high-,middle-,low-dose group were higher than iAs5+(P ＜ 0.05).Meanwhile,there was a significant positive relationship between the expression of MRP2 and the content of iAs3+,MMA and DMA in iAs3+ exposed group(r =0.575,0.678,0.395,all P ＜ 0.05).There was also a significant correlation between the expression of MRP2 and MMA and IMA in iAs5+ exposed group(r =0.593,0.643,all P ＜ 0.05).There was no significant relationship between the expression of MRP2 and the content of iAs5+in iAs5+ exposed group.Conclusions The expression of MRP2 is increased with increasing dose of arsenic exposure,thus resulting in compensatory changes on MRP2 expression in the liver cell membrane.MRP2 efflux may play an important role in the metabolic pathways of iAs3+.The level or load of arsenic methylation in liver is closely related with MRP2 expression.

Objective To observe the infection prevention, wound healing effect and safety of nanometer silver in treatment of Ⅱ degree burn wound. Methods The patients with 6%-10% TBSA Ⅱ degree burn wound ( deep or superficial) were randomly divided into test group ( treated with nanome-ter silver, n =35) and control group (treated with 1% sulfadiazine silver, n =35). Each group was reg-ulated to change dressing and medication one time a day for seven days on 5% superficial Ⅱ degree burn wound. Then, 1% iodophors and gauze were used for change dressing. Before and after change dressing, bacterial culture was done in two groups to observe the time for wound healing. The blood collected before change dressing and at days 1,7 and 14 after change dressing and urine within 24 hours were employed for detecting serum silver level and mean silver level in urine by using inductively coupled plasma mass-spec-trum ( thermoelectricity of American Ⅹ Series Ⅱ ). In the meantime, the liver and renal function was e-valuated at days 7 and 14. Results Positive rate of bacterial culture in test group and control group was 3% and 3.1% respectively after treatment, which showed a decrease compared with the levels before treatment (12. 1% and 15.6% respectively), with no statistical difference. The wound healing time of test group was (9. 18 ± 1.9) days, which was shorter than ( 12.9 ± 1.3 ) days in control group, with sta-tistical difference (P<0.01). Before treatment, the silver level of blood was ( 1.55 ± 1.26) μL and ( 1.54 ± 1.28 ) μg/L respectively in test group and control group, and silver level of urine within 24 hours was ( 1.67 ± 1.05 ) μg and ( 1.87 ± 1.37) μg respectively test group and control group, with no statistical difference (P > 0. 05 ). Silver medication could elevate the serum silver level ( P < 0.01 ), with lower level in test group than control group (P <0. 01 ). Average silver level of urine within 24 hours showed similar change with that in the serum. The patients showed normal renal function, with no abnormal change of ALT. Conclusions For Ⅱ degree burn wound, nanometer silver can more significantly short-en wound healing time compared with sulfadiazine silver. Moreover, nanometer silver has higher degree of safety on silve metabolism and is an ideal medcation for burn wound.
