Tibetan medicine Liuwei Muxiang pills (LWMX pills) effectively protects mice from chronic non-atrophic gastritis.

BACKGROUND: Chronic non-atrophic gastritis (CNG) is the most common type of chronic gastritis. If not actively treated, it may induce gastric cancer (GC). Western medicine is effective in CNG, but there are more adverse reactions after long-term medication, and it is easy to relapse after treatment, which affects patients' health and life. Tibetan medicine Liuwei Muxiang Pills (LWMX pills) is a traditional Tibetan medicine compound, which has a unique curative effect in the treatment of gastric inflammation, especially chronic non-atrophic gastritis. However, the mechanisms of LWMX pills for treatment CNG still remain poor known. PURPOSE: The aim of this study was to evaluate the therapeutic intervention potential of Tibetan medicine LWMX pills on CNG and explore its potential mechanisms in mice models. METHODS: The mice models was established to evaluate the therapeutic effect of LWMX pills on CNG. The main components of LWMX pills were analyzed by GC-MS. HE staining, immunohistochemistry, proteomics and Western Blot were used to analyze the potential mechanism of LWMX pills for CNG treatment. RESULTS: In the present study, LWMX pills containing costunolide, dehydrocostuslactone and antioxidants were found. IF results showed that the expression of ALDH1B1 in the control group was significantly lower than that in the model group in the gastric mucosa tissue, and the expression of ALDH1B1 was significantly lower in the 25 mg/ml LWMX Pills group (one month) and 25 mg/ml LWMX Pills group (two months) than in the model group. IHC revealed that model group samples expressed higher levels of Furin than 25 mg/ml LWMX Pills group samples, as evidenced by very strong staining of Furin in gastric mucosal cells. However, AMY2 staining in gastric mucosal cells did not differ significantly between the treated and control groups. the protein expression levels of these proteins were decreased in 25 mg/mL LWMX pills. Meanwhile, we found that the CAM1 protein expression in the in 25 mg/ml LWMX pills group (two mouths) was increased compared to the in 25 mg/ml LWMX pills group (one mouths).Western blotting showed that the protein expression levels of Furin, AMY2A, CPA3, ALDH1B1, Cam1, COXII, IL-6, IL-1ß were decreased in 25 mg/mL LWMX pills. Meanwhile, that the CAM1 protein expression in the in 25 mg/ml LWMX pills group (two mouths) was increased compared to the in 25 mg/ml LWMX pills group (one mouths). CONCLUSION: 25mg/ml LWMX pill treatment for one month had better therapeutic effect on mice CNG. Further proteomic results showed that LWMX pills maintain gastric function by inhibiting inflammation and oxidative stress, and we also found that LWMX pills regulate the expression of proteins associated with cancer development (Amy2, Furin).

[Exploration and practice on construction of Tibetan medicine prescription information database and knowledge discovery].

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.

[Study on regularity of drug use in Tibetan medicine treating hypertension based on multi-center clinical medical records and "prescription-property-efficacy-disease"].

This study aimed to explore the rule of Tibetan medicine in clinical treatment of hypertension( k Hrag-rLung-stod-vtshangs) and analyze the characteristics of its prescriptions. One hundred and thirty-seven cases of hypertension treated Tibetan medicine were collected. Data mining,Gephi,Cytoscape and other methods and software were used to analyze the characteristics of Tibetan medicine. The results showed that there were 44 cases of r Lung-type hypertension in clinical medical records,while 57 cases of k Hrag-type hypertension. There were 103 treatment prescriptions. The frequency of these prescriptions covered Twenty-five Yuganzi Pills( 96 times),Seventy Pearl Pills( 80 times),Eight Chenxiang Pills( 75 times),and Sanwei Ganlu Powder( 62 times),and they were highly correlated,with confidence greater than 95%. There were 332 prescriptions involved in the prescriptions which is core prescription medicines. This study first proposed the dosage analysis method of Tibetan medicine prescription medicines,and obtained the more dosage of Chebulae Fructus,Phyllanthi Fructus,Aucklandiae Radix,Aquilariae Lignum Resinatum and so on. The correlation analysis of the prescription medicines found that Carthami Flos,Myristicae Semen,Bambusae Concretio Silicea,Caryophylli Flos,Amomi Fructus Rotundus led by Tsaoko Fructus had a high correlation and a confidence greater than 75%. These herbs were guaranteed when Tibetan medicine was used in combination. The key drugs for protecting viscera and regulating the three gastric fires. The prescription is mainly cold,blunt,sparse and rough. Its efficacy focuses on the pathogenesis of blood fever,blood stickiness and venous blockage caused by heat,sharpness,odor and stickiness. It mainly treats Tibetan medicine diseases such as k Hrag-r Lung-stod-vtshangs and k Hrag-vpel( polyemia). It is suggested that Tibetan medicine has a three-in-one invisible treatment principle of " clearing blood-heat,opening vessel and regulating stomach-fire" in the treatment of hypertension,which attributed to both cardiovascular function and gastrointestinal metabolic function. This may be a significant and invisible knowledge of Tibetan medicine in the treatment of hypertension.
