This study established an HPLC fingerprint of Tibetan medicine Shaji Gao from different habitats and lay a foundation for Shaji Gao varieties identification and preparation process. The chromatographic condition was as follow: Agilent zorbax SB-C18 (4.6 mm x 250 mm, 5 μm) eluted with the mobile phases of acetonitrile and 0.4% phosphoric acid water in gradient mode. The flow rate was 1.0 mL x min(-1), and the detection wavelength was set at 360 nm. The fingerprints of 15 batches Shaji Gao were carried out by similarity comparation, 7 chromatographic peaks were extracted as the common peaks of fingerprint, 3 peaks were identified, which were quercetin, kaempferol and isorhamnetin. The similarity degrees of 14 batches of samples were above 0.9 and 1 batch of samples was below 0.9. This is the first established fingerprint of Shaji Gao by using HPLC. This method has good precision, stability and repeatability that it could provide basis for quality control and evaluation of Shaji Gao.
The ITS2 barcode was used toidentify Tibetan medicine "Dida", and tosecure its quality and safety in medication. A total of 13 species, 151 experimental samples for the study from the Tibetan Plateau, including Gentianaceae Swertia, Halenia, Gentianopsis, Comastoma, Lomatogonium ITS2 sequences were amplified, and purified PCR products were sequenced. Sequence assembly and consensus sequence generation were performed using the CodonCode Aligner V3.7.1. The Kimura 2-Parameter (K2P) distances were calculated using MEGA 6.0. The neighbor-joining (NJ) phylogenetic trees were constructed. There are 31 haplotypes among 231 bp after alignment of all ITS2 sequence haplotypes, and the average G±C content of 61.40%. The NJ tree strongly supported that every species clustered into their own clade and high identification success rate, except that Swertia bifolia and Swertia wolfangiana could not be distinguished from each other based on the sequence divergences. DNA barcoding could be used as a fast and accurate identification method to distinguish Tibetan medicine "Dida" to ensure its safe use.
Hippophae rhamnoides subsp. sinensis Rousi, Hippophae gyantsensis (Rousi) Y. S. Lian, Hippophae neurocarpa S. W. Liu & T. N. He and Hippophae tibetana Schlechtendal are typically used under one name “Shaji”, to treat cardiovascular diseases and lung disorders in Tibetan medicine (TM). A complete set of infrared (IR) macro-fingerprints of these four Hippophae species should be characterized and compared simply, accurately, and in detail for identification. In the present study, tri-step IR spectroscopy, which included Fourier transform IR (FT-IR) spectroscopy, second derivative IR (SD-IR) spectroscopy and two-dimensional correlation IR (2D-IR) spectroscopy, was employed to discriminate the four Hippophae species and their corresponding extracts using different solvents. The relevant spectra exhibited the holistic chemical compositions and variations. Flavonoids, fatty acids and sugars were found to be the main chemical components. Characteristic peak positions, intensities and shapes derived from FT-IR, SD-IR and 2D-IR spectra provided valuable information for sample discrimination. Principal component analysis (PCA) of spectral differences was performed to illustrate the objective identification. Results showed that the species and their extracts can be clearly distinguished. Thus, a quick, precise and effective tri-step IR spectroscopy combined with PCA can be applied to identify and discriminate medicinal materials and their extracts in TM research.
<p>Previous voxel-based morphometry (VBM) studies have revealed that meditation is associated with structural brain changes in regions underlying cognitive processes that are required for attention or mindfulness during meditation. This VBM study examined brain changes related to the practice of an emotion-oriented meditation: loving-kindness meditation (LKM). A 3 T magnetic resonance imaging (MRI) scanner captured images of the brain structures of 25 men, 10 of whom had practiced LKM in the Theravada tradition for at least 5 years. Compared with novices, more gray matter volume was detected in the right angular and posterior parahippocampal gyri in LKM experts. The right angular gyrus has not been previously reported to have structural differences associated with meditation, and its specific role in mind and cognitive empathy theory suggests the uniqueness of this finding for LKM practice. These regions are important for affective regulation associated with empathic response, anxiety and mood. At the same time, gray matter volume in the left temporal lobe in the LKM experts appeared to be greater, an observation that has also been reported in previous MRI meditation studies on meditation styles other than LKM. Overall, the findings of our study suggest that experience in LKM may influence brain structures associated with affective regulation.</p>

Objectives: Meconopsis integrifolia (M. integrifolia) is one of the most popular members in Traditional Tibetan Medicine. This study aimed to investigate the anticancer effect of M. integrifolia and to detect the underlying mechanisms of these effects. Methods: 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and trypan blue assay were used to evaluate the cytotoxicity of M. integrifolia. Changes in cell nuclear morphology and reactive oxygen species (ROS) level were observed by fluorescent microscopy. Apoptosis ratio, DNA damage and mitochondrial membrane potential (MMP) loss were analyzed by flow cytometry. Western blotting assay was adopted to detect the proteins related to apoptosis. Immunofluorescence was used to observe the release of cytochrome C. Results: The obtained data revealed that M. integrifolia could significantly inhibit K562 cell viability, mainly by targeting apoptosis induction and cell cycle arrest in G2/M phase. Collapse in cell morphology, chromatin condensation, DNA damage and ROS accumulation were observed. Further mechanism detection revealed that mitochondrion might be a key factor in M. integrifolia-induced apoptosis. Conclusions: M. integrifolia could induce mitochondria mediated apoptosis and cell cycle arrest in G2/M phase with little damage to normal cells, suggesting that M. integrifolia might be a potential and efficient anticancer agent that deserves further investigation.

Using diffusion tensor imaging, several recent studies have shown that training results in changes in white matter efficiency as measured by fractional anisotropy (FA). In our work, we found that a form of mindfulness meditation, integrative body–mind training (IBMT), improved FA in areas surrounding the anterior cingulate cortex after 4-wk training more than controls given relaxation training. Reductions in radial diffusivity (RD) have been interpreted as improved myelin but reductions in axial diffusivity (AD) involve other mechanisms, such as axonal density. We now report that after 4-wk training with IBMT, both RD and AD decrease accompanied by increased FA, indicating improved efficiency of white matter involves increased myelin as well as other axonal changes. However, 2-wk IBMT reduced AD, but not RD or FA, and improved moods. Our results demonstrate the time-course of white matter neuroplasticity in short-term meditation. This dynamic pattern of white matter change involving the anterior cingulate cortex, a part of the brain network related to self-regulation, could provide a means for intervention to improve or prevent mental disorders.

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.

As metabolomics is widely used in the study of disease mechanisms, an increasing number of studies have found that metabolites play an important role in the occurrence of diseases. The aim of this study is to investigate the effects and mechanisms of quercetin in high-fat-sucrose diet (HFD)-induced nonalcoholic fatty liver disease (NAFLD) development using nontargeted metabolomics. A rat model of NAFLD was established by feeding with an HFD for 30 and 50 days. The results indicated quercetin exhibited hepatoprotective activity in 30-day HFD-induced NAFLD rats by regulating fatty acid related metabolites (adrenic acid, etc.), inflammation-related metabolites (arachidonic acid, etc.), oxidative stress-related metabolites (2-hydroxybutyric acid) and other differential metabolites (citric acid, etc.). However, quercetin did not improve NAFLD in the 50-day HFD; perhaps quercetin was unable to reverse the inflammation induced by a long-term high-fat diet. These data indicate that dietary quercetin may be beneficial to NAFLD in early stages. Furthermore, combining metabolomics and experimental approaches opens avenues to study the effects and mechanisms of drugs for complex diseases.

In this study, a computer-based network pharmacology approach was applied to investigate the potential mechanism and important components of Rhodiola crenulata in the protection of H9c2 cells against hydrogen peroxide (H₂O₂)-induced oxidative stress. The intestinal absorption liquid of R. crenulata enhanced the cell viability, maintained cell morphology and inhibited cell apoptosis in the H₂O₂-induced oxidative stress in H9c2. Then, computer-based network pharmacology was used to analyze the relevant mechanism. A total of 133 oxidative stress-related compounds were screened out; and 26 of them occupied the top 20%, and all of the compounds enriched in 43 oxidative stress-related key targets. Finally, a "compound-target-pathway-function" network was constructed. Based on the analysis of the network pharmacology, R. crenulata protected H9c2 cells against H₂O₂-induced oxidative stress probably by affecting apoptosis-related processes, such as cell death, nitric oxide metabolism, oxidative stress, mitochondrial mechanism, redox process, redox-related enzyme activty and other oxidative stress-related process. And salidroside, ethyl gallate and catechins, which were the main components of R. crenulata, played an important role in this process. Therefore, the potential mechanism and important components of R. crenulata revealed the protective effect on oxidative stress. This study shows a multi-component, multi-target and overall regulation effect of R. crenulata on the oxidative stress, and provides a reliable reference for subsequent systematic experimental studies for the pharmacodynamic material foundation and mechanism of action R. crenulata.
Liver disease is one of the most risk factors threatening human health. It is of great significance to find drugs that can treat liver diseases, especially for acute and chronic hepatitis, non-alcoholic fatty liver disease, and liver cancer. The search for drugs with good efficacy from traditional natural medicines has attracted more and more attention. Tibetan medicine, one of the China's traditional medical systems, has been widely used by the Tibetan people for the prevention and treatment of liver diseases for hundreds of years. The present paper summarized the natural Tibetan medicines that have been used in Tibetan traditional system of medicine to treat liver diseases by bibliographic investigation of 22 Tibetan medicine monographs and drug standards. One hundred and ninety three species including 181 plants, 7 animals, and 5 minerals were found to treat liver diseases in traditional Tibetan medicine system. The most frequently used species are Carthamus tinctorius, Brag-zhun, Swertia chirayita, Swertia mussotii, Halenia elliptica, Herpetospermum pedunculosum, and Phyllanthus emblica. Their names, families, medicinal parts, traditional uses, phytochemicals information, and pharmacological activities were described in detail. These natural medicines might be a valuable gift from the old Tibetan medicine to the world, and would be potential drug candidates for the treatment of liver diseases. Further studies are needed to prove their medicinal values in liver diseases treatment, identify bioactive compounds, elucidate the underlying mechanism of action, and clarify their side effects or toxicity with the help of modern phytochemical, pharmacological, metabonomics, and/or clinical trial methods.
<br>In traditional Chinese medicine (TCM), multicomponent and principally plant-derived drugs are used for disease prevention, symptom amelioration and treatment in a personalized manner. Because of their complex composition and consequent multiple targets and treatment objectives, the application of omics techniques and other integrative approaches seems inherently appropriate and even necessary for the demonstration of their potential preclinical and clinical safety and efficacy. This perspectives article provides proposals for the application of omics methods to the investigation of complex herbal products (CHP), 1 1 Complex herbal products are used in many other forms of Asian medicines than Chinese medicines, such as traditional Indian medicine (Ayurveda), Japanese medicine (Kampo), Korean medicine, Tibetan medicine <b>etc.</b>, although the conceptual background for use may differ. including Chinese herbal medicines (CHM), both <b>in vitro</b> and <b>in vivo</b>, for preclinical and clinical toxicity, pharmacokinetics, pharmacodynamics and efficacy tests. Ultimately, such approaches could aid regulatory scrutiny and potential acceptance, although currently there is no regulatory requirement of omics-based data in any submitted dossier to any regulatory agency, including for conventional drugs and CHP. However, it has been acknowledged that such studies are being increasingly performed, and almost surely will eventually be included into regulatory submission dossiers, possibly initially as supplementary materials. Specifically for CHM and CHP, omics can play a role both in determining product composition and its variability and in monitoring biological effects in carefully selected platforms. Predicting the future is difficult, but it seems possible that regulatory acceptance of omics techniques and a systems biology approach for the study of TCM, CHM and CHP will not be long delayed. It is expected that current studies and plans employing omics techniques and other integrative approaches will prove to be positive and informative.
A phytochemical investigation on Lagotis brevituba led to the isolation and characterisation of 11 phenolic compounds: p-hydroxy-benzoic acid 1, methyl 3,4-dihydroxybenzoate 2, vanillic acid 3, protocatechuic acid 4, caffeic acid 5, glucose ester of (E)-ferulic acid 6, p-coumaric acid 7, vanillin 8, diosmetin-7-O-β-d-glucoside 9, chrysoeriol 10 and luteolin 11. Their structures were elucidated using spectroscopic methods and by comparison with data in the literature. Compounds 1-6 were first obtained from the genus Lagotis, and compounds 1-9 were isolated from L. brevituba for the first time. Compound 4 and 11 displayed remarkable antioxidant activities against DPPH radical (IC50 = 5.60 ± 0.09, 27.5 ± 0.06 mg/L, respectively), which were superior to positive control rutin. And compound 11 was also superior to rutin in ABTS assay (IC50 = 2.04 ± 0.13 mg/L).

Linn. (syn. ), commonly known as Yuganzi in Chinese and Indian gooseberry or amla in English, is a Phyllanthaceaeous plant indigenously grown in the area of Nepal, India, Sri Lanka, throughout South-East Asia to southern China. It is also widely cultivated for its fruits throughout its natural area of distribution, particularly in southern China and India. All parts of the plant are used for medicinal purposes, especially the fruit, which has been used in traditional Chinese medicine and Indian Ayurveda for the treatment of diarrhea, jaundice, and inflammation. Modern pharmacological researches revealed its antidiabetic, hypolipidemic, antibacterial, antioxidant, antiulcerogenic, hepatoprotective, gastroprotective, and chemopreventive properties. The fruit of the plant is also used as a tonic to build up lost vitality and vigor with its highly nutritious and abundant phenolic compounds, tannins, flavonoids, vitamins, amino acids, and minerals [1, 2].
The herbs used as the material for traditional Chinese medicine are mostly planted at mountain areas where there is appropriate weather condition. Due to the complex terrain condition in mountain area, the planting at such places is always associated with a scattered pattern, which inevitably bring difficulty to the work of accurate measurement for the planting area. Advanced research about monitoring the planting area for medicine-herb under complex environmental condition is so critical and meaningful for developing the medicine-herb planting to a large scale and an industry. Therefore, this research, taking the planting of Herpetospermum pedunculosum in Luding county as an example, utilizes RS&GIS: using the image data from TM and ETM datum as the remote sensing information source, integrating GPS data from quadrat survey on the spots, and analyzing on a GIS platform, to extract the planting area of H. pedunculosum in Luding county. The results indicate that: (1) the method and technology used to estimate the planting area of H. pedunculosum are feasible and can be applied to monitoring the planting area of medicine-herb at mountain area under complex environmental conditions: (2) the planting area of H. pedunculosum in Luding county is estimated to be 857. 246 acres by the methods utilized in this research, which is closed to the value from local statistical data with an error range less than 5%; (3) in consideration of those inevitable errorrs generating from the procedures such as remote sensing data acquisition, data preprocessing, data interpretation, and so on, and the fact that the classification of remote sensing data, which must be implemented by those above procedures, was used directly to extract the herb type, the accuracy of area estimation for the herb is significantly influenced by the accuracy of classification for herb type, and the estimated area is inevitably associated with some error.
OBJECTIVE: To explore the protective effects of Tibetan medicine Zuo-Mu-A Decoction (, ZMAD) on the blood parameters and myocardium of high altitude polycythemia (HAPC) model rats.METHODS: Forty male Wistar rats were randomly divided into 4 groups by a random number table, including the normal, model, Rhodiola rosea L. (RRL) and ZMAD groups (10 in each group). Every group was raised in Lhasa to create a HAPC model except the normal group. After modeling, rats in the RRL and the ZMAD groups were administered intragastrically with RRL (20 mL/kg) and ZMAD (7.5 mL/kg) once a day for 2 months, respectively; for the normal and the model groups, 5 mL of distilled water was administered intragastrically instead of decoction. Then routine blood and hematologic rheology parameters were taken, levels of erythropoietin and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were tested, and ultrastructural change in the left ventricular myocardium was observed using transmission electron microscopy.
RESULTS: Compared with the model group, ZMAD significantly reduced the red blood cell count, hemoglobin levels, whole blood viscosity at low/middle shear rates, plasma viscosity, erythrocyte electrophoretic time, erythropoietin and 8-OHdG levels, and also increased the erythrocyte deformation index (P<0.05). There was no difference in all results between the RRL and the ZMAD groups. The cardiac muscle fibers were well-protected, mitochondrial matrix swelled mildly and ultrastructure changes were less prominent in the ZMAD group compared with the model group.
CONCLUSION: ZMAD has significant protective effects on the blood parameters against HAPC, and also has the beneficial effect in protecting against myocardial injury.
