RESUMO
To provide the ancient literary evidence support for the clinical application and development of classical prescription based on systematical collection and analysis of the ancient Chinese medical literature containing Jinshui Liujun Jian, including its origin and development. Bibliometric analysis was used and information of Jinshui Liujun Jian in ancient Chinese medical literature was then collected for statistical analysis of formula compositions, main indications, dosage, preparation methods, etc. A total of 151 valid items of data were obtained from 48 ancient Chinese medicine books. Jinshui Liujun Jian was first recorded in Jingyue Quanshu written by ZHANG Jiebin. This prescription consisted of Rehmanniae Radix Praeparata, Angelicae Sinensis Radix, Pinelliae Rhizome, Citri Reticulatae Pericarpium, Poria and Glycyrrhizae Radix et Rhizome Praeparata cum Melle, and it was mainly used to treat the deficiency of lung and kidney, edema and excess production of phlegm, or Yin deficiency in the old, insufficient blood-qi, wind-cold evil, cough and disgusting, asthma and excessive phlegm. Doctors in later dynasties mostly followed the prescription compositions, dosages and indications in Jingyue Quanshu, and extended the clinical application of this prescription.

This paper deals with the application of ultra-performance liquid chromatography tandem quadrupole time of flight mass spectrometry(UPLC-ESI-Q-TOF-MS/MS) method to rapidly determine and analyze the chemical constituents of methanol extract of Urtica hyperborea. We employed UPLC YMC-Triart C18(2. 1 mm×100 mm,1. 9 µm) column to UPLC analysis with acetonitrile-water(containing 0. 4% formic acid) in gradient as mobile phase. The flow rate was 0. 3 m L·min-1 gradient elution and column temperature was 30â; the injection volume was 4 µL. ESI ion source was used to ensure the data collected in anegative ion mode. The chemical components of U. hyperborea were identified through retention time,exact relative molecular mass,cleavage fragments of MS/MS and reported data.The results indicated that a total of 31 compounds were identified,including 8 flavonoids,14 phenolic compounds,8 phenylpropanoids(4 coumarins and 4 lignans),and 1 steroidal compound,13 of which were confirmed by comparison. The UPLC-ESI-Q-TOF-MS/MS method could rapid identify the chemical components of U. hyperborea. The above compounds were discovered in U. hyperborea for the first time,which could provide theoretical foundation for further research on the basis of the pharmacodynamics of U. hyperborea.

In this study,mouse models of benign prostatic hyperplasia induced by subcutaneous injection of testosterone propionate was used to investigate the therapeutic effect and mechanism of Urtica hyperborean( UW) extracts on prostate hyperplasia in mice. The effects of UW extracts on prostate index,serum epidermal growth factor( EGF) and dihydrotestosterone( DHT) in model mice were observed,and the EGF and anti-apoptotic factor( Bcl-2) mRNA expression levels were detected as well as pathological changes in prostate tissue. The results showed that the ethyl acetate extraction and alcohol soluble fraction of the UW could significantly reduce the prostate index,reduce the serum DHT and EGF levels( P<0. 01),and significantly decrease the EGF and Bcl-2 mRNA expression( P<0. 01),significantly improved the morphological structure of prostate tissue. The above results confirmed that ethyl acetate extract and alcohol-soluble parts of UW have a good preventive effect on mice prostatic hyperplasia model,and its mechanism may be to reduce androgen levels by regulating polypeptide growth factors and/or inhibiting cell hyperproliferation and promoting apoptosis. This study laid the foundation for the further research on UW.

In this study, a non-targeted metabolic profiling method based on ultra-performance liquid chromatography-high resolution mass spectrometry (UPLC-HRMS) was used to characterize the plasma metabolic profile associated with the protective effects of the Sagittaria sagittifolia polysaccharide (SSP) on isoniazid (INH)-and rifampicin (RFP)-induced hepatotoxicity in mice. Fourteen potential biomarkers were identified from the plasma of SSP-treated mice. The protective effects of SSP on hepatotoxicity caused by the combination of INH and RFP (INH/RFP) were further elucidated by investigating the related metabolic pathways. INH/RFP was found to disrupt fatty acid metabolism, the tricarboxylic acid cycle, amino acid metabolism, taurine metabolism, and the ornithine cycle. The results of the metabolomics study showed that SSP provided protective effects against INH/RFP-induced liver injury by partially regulating perturbed metabolic pathways.

INTRODUCTION: Lamiophlomis rotata (Duyiwei) is a folk herbal medicine that traditionally has been used in China as a hemostatic agent. Raw plant materials used for medicinal products from different geographical regions are often inconsistent in chemical composition. Metabolic fingerprinting provides a new approach for distinguishing the geographical origins of L. rotata. OBJECTIVE: To identify metabolites that contribute to the different geographical regions of L. rotata samples. METHODS: Lamiophlomis rotata metabolomics were performed by (1)H-nuclear magnetic resonance (NMR) spectroscopy and multivariate statistical analyses. The L. rotata metabolic profile was prepared for NMR measurements using methanol-d4 solvent. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) were applied to analyse the L. rotata (1)H-NMR spectroscopy data. RESULTS: Nine iridoid glycosides, one flavonoid and three phenylpropanoid glycosides were detected in L. rotata by (1)H-NMR spectroscopy. (1)H-NMR measurements and multivariate analysis were used to successfully discriminate samples from three different locations. CONCLUSION: The NMR-based analysis of L. rotata is a more comprehensive approach than traditional chromatographic methods. Simple sample preparation, rapidity and reproducibility of are additional advantages of NMR analysis.

Rhizoma coptidis, a broadly used medicinal plant, originates from the dried rhizomes of three species in Chinese pharmacopoeia, namely, Coptis chinensis Franch, Coptis deltoidea C. Y. Cheng et Hsiao, and Coptis teeta Wall. In this study, a novel approach using (1)H NMR spectroscopy combined with multivariate analysis was introduced to differentiate the three species and identify potential metabolic markers for better controlling the quality of rhizoma coptidis. A broad range of metabolites including alkaloids, sugars, organic acids, amino acids, and fatty acids present in rhizoma coptidis were detected by means of (1)H NMR spectroscopy. Principal component analysis (PCA) of the (1)H NMR data set showed a clear separation between all samples by PC1 and PC3, and some metabolites that could be responsible for the discrimination of the three species were identified. An analysis of variance (ANOVA) was performed to statistically verify the significance of differences in metabolite levels between species. By combining PCA and ANOVA, significantly higher contents of palmatine, coptisine, epiberberine, columbamine, and fatty acids together with lower contents of jateorrhizine were found in Coptis chinensis, whereas Coptis deltoidea and Coptis teetA showed the highest levels of sucrose and chlorogenic acid, respectively. This study indicates that metabolites of rhizoma coptidis vary with the species and the proposed method is suitable for metabolic fingerprinting analysis to check the genuine origin of rhizoma coptidis.

Swertia mussotii Franch. and Swertia chirayita Buch.-Ham. have been commonly used under the same name "Zangyinchen" for the treatment of liver and gallbladder diseases in traditional Tibetan medicine. Detailed characterization and comparison of the complete set of metabolites of these two species are critical for their objective identification and quality control. In this study, a rapid, simple and comprehensive (1)H NMR-based metabolomics method was first developed to differentiate the two species. A broad range of metabolites, including iridoid glycosides, xanthones, triterpenoids, flavonoids, carbohydrates, and amino acids, were identified. Statistical analysis showed evident differences between the two species, and the major markers responsible for the differences were screened. In addition, quantitative (1)H NMR method (qHNMR) was used for the target analysis of the discriminating metabolites. The results showed that S. mussotii had significantly higher contents of gentiopicrin, isoorientin, glucose, loganic acid, and choline, whereas S. chirayita exhibited higher levels of swertiamarin, oleanolic acid, valine, and fatty acids. These findings indicate that (1)H NMR-based metabolomics is a reliable and effective method for the metabolic profiling and discrimination of the two Swertia species, and can be used to verify the genuine origin of Zangyinchen.

Improving efficacy of inflammation treatment by increasing drug delivery to the inflammatory sites is a challenging endeavor. N-formyl-methionyl-leucyl-phenylalanine (fMLP), the first discovered leukocyte chemotaxis peptide, is composed of formyl methionine, leucine and phenylalanine. It conjugates with formyl peptide receptors on the target cells with high receptor expression on the surface such as macrophages. With this in mind, we developed a novel fMLP-modified liposome (fMLP-LIP) for enhancing drug delivery to the inflammatory sites and resolving the systemic reaction issue with conventional anti-inflammatory drugs. Being a more stable and cheaper liposomal component than phospholipids, cholesterol (CHO) has been thoroughly investigated as an alternative anchor. In this study, fMLP was covalently conjugated with CHO with polyethylene glycol link to prepare the liposomes, cellular uptake of liposomes by differentiated human U937 cells was examined and cellular uptake experiment in vitro was employed to optimize fMLP-LIP prescription and investigate the uptake mechanism. An in vivo inflammatory model was established to evaluate the targeting performance of fMLP-LIP to inflammatory site. The in vitro and in vivo findings indicate that the fMLP ligands playing an important role in increasing drug delivery to inflammatory sites and fMLP-LIP as a promising anti-inflammatory drug carrier.

Rhizoma coptidis, a broadly used traditional Chinese medicine, derives from the dried rhizomes of Coptis chinensis Franch, Coptis deltoidea C.Y. Cheng et Hsiao and Coptis teeta Wall. Quantitative determination of protoberberine alkaloids in R. coptidis is critical for controlling its quality. In this study, a rapid, simple and accurate quantitative (1)H NMR (qNMR) method was developed for simultaneous determination of berberine, jatrorrhizine, epiberberine, coptisine, palmatine and columbamine in R. coptidis from the three species. Method validation was performed in terms of selectivity, precision, repeatability, stability, accuracy, robustness and linearity. The average recoveries obtained were in the range of 96.9-102.4% for all the six alkaloids. In addition, the qNMR data were analyzed with analysis of variance (ANOVA), hierarchical clustering analysis (HCA) and principal component analysis (PCA), and the results showed that the contents of the active alkaloids have significant difference among the three species. Compared with the conventional HPLC approach, the proposed qNMR method was demonstrated to be a powerful tool for quantifying the six alkaloids due to its unique advantages of high robustness, rapid analysis time and no need of standard compounds for calibration curves preparation. These findings indicate that this method has potential as a reliable method for quality evaluation of herb medicines, especially for protoberberine alkaloid-containing ones.
