A pharmacophore-based study was conducted to investigate the therapeutic activity of the traditional Tibetan medicine Zha Xun (ZX) in liver diseases. In the present study, the protective effect of ZX on the acute liver injury induced by concanavalin A (ConA) and 0.15% carbon tetrachloride (0.15% CCl4) in ICR mice was evaluated, and the results showed that ZX significantly reduced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the ConA-induced acute immune liver injury model and the CCl4-induced acute oxidative liver injury model (P < 0.05). Subsequently, the protective effects of aqueous, 95% ethanol, 60% ethanol and 30% ethanol eluting fractions of ZX, and fulvic acid, the main water-soluble constituent of ZX, were evaluated against acute oxidative liver injury induced by 0.15% CCl4 in mice. The results showed that different solvent-eluting fractions of ZX showed certain hepatoprotective activities, among which the aqueous extract of ZX and 30% ethanol extract of ZX significantly reduced the serum levels of ALT, AST, and lactate dehydrogenase (LDH) in mice (P < 0.05), and the serum levels of LDH in mice were significantly reduced by fulvic acid (P < 0.05), which showed significant hepatoprotective activity. The protective activities and preliminary mechanisms of the total extract of ZX, the aqueous extract of ZX, the 30% ethanol extract of ZX, and fulvic acid against hepatocellular injury in vitro were further evaluated by using the H2O2-induced hepatocellular injury model. The results showed that the components could significantly inhibit H2O2-induced hepatocellular injury, reduce the levels of ALT, alkaline phosphatase (ALP), and LDH, improve the survival rate of hepatocellular cells, and reduce the content of intracellular reactive oxygen species (ROS) in cell culture. At the same time, it can inhibit hepatocyte apoptosis by increasing the expression ratio of Bcl-2/BAX protein and decreasing the expression ratio of cleaved caspase-3/pro caspase-3 protein. The present study showed that ZX has clear hepatoprotective activity in vitro and in vivo, and the different solvent elution fractions of ZX showed certain hepatoprotective activity, among which the aqueous extract of ZX, 30% ethanol extract of ZX had better hepatoprotective activity, and the activity of 60% ethanol extract of ZX was stronger than that of 95% ethanol extract of ZX. The activity of ZX and its water-soluble elution site exerted hepatoprotective effects by inhibiting hepatocyte apoptosis and oxidative stress. The animals used in this experiment and related disposal meet the requirements of animal welfare, and have been reviewed and approved by the Laboratory Animal Management and Use Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences (approval number: 00004018).

By tracing to the origin of Tibetan medicine, it is known that Tibetan medicine absorbs a variety of medical ideas such as traditional Chinese medicine, Vedic medicine, Persian medicine and Byzantine medicine, and forms a unique theoretical system. The meridian-acupoint system and the characteristics and application of external therapies such as bloodletting and moxibustion in Tibetan medicine are analyzed by elaborating the relevant aspects of acupuncture and moxibustion involved in treatment of diseases listed in Medical Canon in Four Sections. The paper emphasizes the introduction of ironing moxibustion and huo'er moxibustion of fire moxibustion and the application of separation-action decoction and ghee therapy in bloodletting, as well as alternative therapy. Besides, by taking the external treatment of cirrhotic ascites and head trauma as an example, the idea of acupuncture and moxibustion therapy in Tibetan medicine embodied in the Medical Canon in Four Sections is explained so as to benefit the development of acupuncture and moxibustion therapy in Tibetan medicine.

Corydalis hendersonii(CH) is a Tibetan folk medicine with the functions of clearing heat, detoxifying, cooling blood, checking diarrhea, and lowering blood pressure. It is often used to treat high altitude polycythemia, vasculitis, peptic ulcer, and diarrhea. Nine compounds were separated from the ethanol extract of CH by silica gel, ODS, Sephadex LH-20 chromatography and semi-preparative HPLC. Their structures were identified as hendersine H(1),hendersine I(2), dehydrocheilanthifoline(3), protopine(4), izmirine(5), 6,7-methylenedioxy-1(2H)-isoquinolinone(6), icariside D_2(7), ethyl 4-(β-D-glucopyranosyloxy)-3-methoxybenzoate(8), 3-hydroxy-4-methoxybenzoic acid(9), respectively, by the spectroscopic data analysis and comparison with those in the literature. Among them, compounds 1 and 2 are new isoquinoline alkaloids, and compounds 7-9 are reported the first time for Corydalis. The hypoglycemic model of H9c2 cardiomyocytes and the inflammatory model of H9c2 cardiomyocytes induced by conditional supernatant were employed to determine the activities of the above compounds. The results showed that 20 μmol·L~(-1) compound 1 had a protective effect on H9c2 cardiomyocytes and 10 μmol·L~(-1) compounds 4 and 5 inhibited H9c2 cardiomyocyte inflammation induced by conditional supernatant.

Aim To explore the mechanism of Tibetan medicine Siwei Huangqi powder(SW)in reducing hypoxic pulmonary hypertension. Methods A total of 110 Wistar rats were randomly divided into normoxia control group,hypoxic control group and hypoxic drug group. The two hypoxic groups were divided into 1,3,7,15 and 30 day group according to the exposure time of hypoxic,10 groups in total. The normoxia control group was placed in the atmospheric environment at an altitude of 2 260 meters without intervention; 10 hypoxic groups were placed in a hypobaric hypoxic chamber with a simulated altitude of 5 000 meters. The hypoxic drug group was given SW suspension(0.42 g/100 g)by gavage,and the hypoxic control group was given normal saline by gavage,once a day. The Ppa and RV/(LV+S)were measured at the corresponding time points in each group; the levels of p-AMPK,ULK-1 and LC3 /LC3 Ⅱ protein in lung tissues were measured by WB method. Results Compared with normoxia control group,the ratio of PA and RV/(LV + s)in hypoxic control group increased gradually with the extension of hypoxic exposure time,which was consistent with the thickness of pulmonary artery smooth muscle layer and the changes of pulmonary tissue subcellular organelles. The expression level of p-AMPK protein in lung tissues was also slightly up-regulated(P<0.05),and ULK-1 and LC3 Ⅱ were significantly up-regulated(P<0.01),especially in acute hypoxic. Compared with the hypoxic control group,the increase of Ppa and the thickening of pulmonary artery smooth muscle layer in the hypoxic drug group were significantly reduced(P<0.050.01),while the expression levels of p-AMPK,ULK-1 and LC3 Ⅱ proteins in lung tissues increased with the extension of hypoxic exposure time(P<0.050.001),especially in chronic hypoxic. Conclusion SW can inhibit hypoxic pulmonary hypertension by up-regulating AMPK autophagy signaling pathway.

This study aimed to explore the underlying framework and data characteristics of Tibetan prescription information. The information on Tibetan medicine prescriptions was collected based on 11 Tibetan medicine classics, such as Four Medical Canons(Si Bu Yi Dian). The optimal classification method was used to summarize the information structure of Tibetan medicine prescriptions and sort out the key problems and solutions in data collection, standardization, translation, and analysis. A total of 11 316 prescriptions were collected, involving 139 011 entries and 63 567 pieces of efficacy information of drugs in prescriptions. The information on Tibe-tan medicine prescriptions could be summarized into a "seven-in-one" framework of "serial number-source-name-composition-efficacy-appendix-remarks" and 18 expansion layers, which contained all information related to the inheritance, processing, origin, dosage, semantics, etc. of prescriptions. Based on the framework, this study proposed a "historical timeline" method for mining the origin of prescription inheritance, a "one body and five layers" method for formulating prescription drug specifications, a "link-split-link" method for constructing efficacy information, and an advanced algorithm suitable for the research of Tibetan prescription knowledge discovery. Tibetan medicine prescriptions have obvious characteristics and advantages under the guidance of the theories of "three factors", "five sources", and "Ro-nus-zhu-rjes" of Tibetan medicine. Based on the characteristics of Tibetan medicine prescriptions, this study proposed a multi-level and multi-attribute underlying data architecture, providing new methods and models for the construction of Tibetan medicine prescription information database and knowledge discovery and improving the consistency and interoperability of Tibetan medicine prescription information with standards at all levels, which is expected to realize the "ancient and modern connection-cleaning up the source-data sharing", so as to promote the informatization and modernization research path of Tibetan medicine prescriptions.

OBJECTIVE@#To assess the effectiveness of Jiuwei Zhuhuang Powder (JWZH), a Tibetan patent medicine in treating upper respiratory tract infection (URTI) associated cough in children.@*METHODS@#The study was a multicenter, randomized, open-label, controlled trial. A total of 142 children aged 2 to 14 years old, with URTI-associated cough within 48 h of onset, were randomly assigned to two groups at a 1:1 ratio by computer-generated randomization sequence. Children were treated with JWZH (1 to 1.5 g, twice to thrice daily) in the treatment group or conventional treatment (Pediatric Paracetamol, Artificial Cow-bezoar and Chlorphenamine Maleate Granules, 0.25 to 1 g, thrice daily) in the control group for 5 days. The primary endpoints were the time to cough resolution and 4-day cough resolution rate. The secondary endpoints were the daily improvement in symptom scores and cough resolution rate during the study period.@*RESULTS@#A total of 138 children were included in the intention-to-treat analysis, with 71 cases in the treatment group and 67 cases in the control group. Compared with the conventional treatment, the children receiving JWZH had a shorter time to cough resolution [hazard ratio, 2.10; 95% confidence interval (CI), 1.29-3.40; P=0.003]. The median time to cough resolution for children receiving JWZH was shorter than that of the conventional treatment (2 days vs. 3 days; P<0.001). The 4-day cough resolution rate in the JWZH group was higher than that of the control group (94.4% vs. 74.6%; risk difference: 19.8%, 95% CI: 8.1%-31.5%; relative risk: 1.265, 95% CI: 1.088-1.470; P=0.001). There were no statistically significant differences in the improvement of other symptoms caused by URTI (P>0.05). Adverse events was reported in 5.6% (4/71) and 4.5% (3/67) in participants of JWZH and PPACCM groups (P>0.05), respectively, which were all mild and resolved without treatment.@*CONCLUSION@#JWZH seemed to be a safe and effective therapy for URTI-associated cough in children. (Trial registration No. ChiCTR2000039421).

Ultra-high performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UPLC-Q-TOF/MS) was used to investigate the effect of Pterocephalus hookeri on serum metabolism of adjuvant arthritis(AA) model rats induced by complete Freund's adjuvant. After the AA model was properly induced, the serum of rats was collected 30 days after treatment. UPLC-Q-TOF-MS chromatograms were collected and analyzed by principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA). The results revealed that compared with the control group, the model group showed increased content of 12 biomarkers in the serum(P<0.05) and reduced content of the other nine biomarkers(P<0.05). P. hookeri extract could recover the above-mentioned 19 biomarkers to a certain range. Pathway enrichment showed that these markers mainly involved eight metabolic pathways, including valine, leucine, and isoleucine degradation, arachidonic acid metabolism, arginine and proline metabolism, glycerol phospholipid metabolism, primary bile acid biosynthesis, bile acid biosynthesis, tryptophan metabolism, and unsaturated fatty acid biosynthesis. The findings of this study demonstrate that P. hookeri extract can regulate metabolic disorders and promote the regression of metabolic phenotype to the normal level to exert the therapeutic effect on AA rats. This study is expected to provide a certain scientific basis for the biological research on the treatment of rheumatoid arthritis by P. hookeri.

The present study investigated the mechanism of the Tibetan medicine Ershiwuwei Songshi Pills(ESP) against the liver injury induced by acetaminophen(APAP) in mice based on the kelch-like ECH-associated protein 1(Keap1)/nuclear transcription factor E2 related factor 2(Nrf2) and Toll-like receptor 4(TLR4)/nuclear factor-kappa B(NF-κB) p65 signaling pathways. Kunming mice were randomly divided into a blank control group, a model group, an N-acetyl-L-cysteine(NAC) group, and high-(400 mg·kg~(-1)), medium-(200 mg·kg~(-1)), and low-dose(100 mg·kg~(-1)) ESP groups. After 14 days of continuous administration, except for those in the control group, the mice were intraperitoneally injected with 200 mg·kg~(-1) APAP. After 12 h, the serum and liver tissues of mice were collected. Hematoxylin-eosin(HE) staining was performed on pathological sections of the liver, and the levels of aspartate aminotransferase(AST) and alanine aminotransferase(ALT) in the serum and the levels of glutathione(GSH), malondialdehyde(MDA), superoxide dismutase(SOD), catalase(CAT), myeloperoxidase(MPO), and total antioxidant capacity(T-AOC) in liver tissue homogenate were detected to observe and analyze the protective effect of ESP on APAP-induced liver injury in mice. The serum levels of tumor necrosis factor-alpha(TNF-α), interleukin-1 beta(IL-1β), and interleukin-6(IL-6) were determined by enzyme-linked immunosorbent assay(ELISA). The protein expression of Nrf2, Keap1, TLR4, and NF-κB p65 in the liver was determined by Western blot. Quantitative real-time was used to determine the mRNA expression of glutamate-cysteine ligase catalytic subunit(GCLC), glutamate-cysteine ligase regulatory subunit(GCLM), heme oxygenase-1(HO-1), and NAD(P)H dehydrogenase quinone 1(NQO-1) in the liver to explore the mechanism of ESP in improving APAP-induced liver damage in mice. As revealed by results, compared with the model group, the ESP groups showed improved liver pathological damage, decreased ALT and AST levels in the serum and MDA and MPO content in the liver, increased GSH, SOD, CAT, and T-AOC in the liver, reduced TNF-α and IL-6 levels in the serum, down-regulated expression of Keap1 in the liver cytoplasm and NF-κB p65 in the liver nucleus, up-regulated expression of Nrf2 in the liver nucleus, insignificant change in TLR4 expression, and elevated relative mRNA expression levels of antioxidant genes GCLC, GCLM, HO-1, and NQO-1. ESP can reduce the oxidative damage and inflammation caused by APAP, and the mechanism may be related to the Keap1/Nrf2 signaling pathway and the signal transduction factors on the TLR4/NF-κB p65 pathway.

Abstract@#In the late 16<sup>th</sup> century, Tibetan medical schools which were based on Indian Ayurvedic medicine were spread in Mongolia when Buddhism was revived the third time in Mongolia. This was a brand new page in the history of the Mongolian health system. Monasteries were set up in every corner and larger monasteries had doctor’s schools to train tens of doctors. At the end of the 17<sup>th</sup> century, Mongolian doctors, scholars started translating and explaining the fundamentals of Indian Ayurveda and Tibetan medicine and even established new branches (schools) blending the Tibetan theory and treatment methods with their empirical knowledge.@*Conclusion@#At that time, in the 18<sup>th</sup> century, complete bases were established for the start of the golden period of Mongolian medical development which was characterized by theoretical and practical compliance with the “Four Medical Tantras”. Tens of books of this time were written in the Mongolian and Tibetan languages by Mongolian doctors and scholars alike. A new paradigm containing progress, unique opinions can be seen on pages of “The Mongolian Four Medical Tantras” written by Sumbe khamba Ishbaljor, and “Satisfaction for the Readers” or Uzegsdiin Bayasgalan by Jigmeddanzan jamts and “Secrets of Prescription Recipes” or Uvidasyn Dalai by Mindol Jambal. These scholars reflected new concepts that were not specifically clear in the Four Fundamentals such as warm and cold diseases, which were the basis to categorize cold and common diseases and treat them differently, and the theoretical and practical understanding of the categorization of infectious diseases, in their book.
