[Huazhi Rougan Granules attenuates steatosis in cell model of nonalcoholic fatty liver disease by inducing autophagy].

To investigate the effect of Huazhi Rougan Granules(HZRG) on autophagy in a steatotic hepatocyte model of free fatty acid(FFA)-induced nonalcoholic fatty liver disease(NAFLD) and explore the possible mechanism. FFA solution prepared by mixing palmitic acid(PA) and oleic acid(OA) at the ratio of 1∶2 was used to induce hepatic steatosis in L02 cells after 24 h treatment, and an in vitro NAFLD cell model was established. After termination of incubation, cell counting kit-8(CCK-8) assay was performed to detect the cell viability; Oil red O staining was employed to detect the intracellular lipid accumulation; enzyme-linked immunosorbnent assay(ELISA) was performed to measure the level of triglyceride(TG); to monitor autophagy in L02 cells, transmission electron microscopy(TEM) was used to observe the autophagosomes; LysoBrite Red was used to detect the pH change in lysosome; transfection with mRFP-GFP-LC3 adenovirus was conducted to observe the autophagic flux; Western blot was performed to determine the expression of autophagy marker LC3B-Ⅰ/LC3B-Ⅱ, autophagy substrate p62 and silent information regulator 1(SIRT1)/adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK) signaling pathway.

[Pharmacodynamic mechanism of Tibetan medicine Liurui Capsules on experimental autoimmune uveitis in rats based on network pharmacology and animal experiments].

By integrating network pharmacology and animal experiments, we studied the pharmacodynamic mechanism of the Tibetan medicine Liurui Capsules in the treatment of experimental autoimmune uveitis(EAU). The active ingredients and targets of Liurui Capsules were searched against the Encyclopedia of Traditional Chinese Medicine(ETCM), Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine(BATMAN-TCM), and relevant literatures. The EAU-related targets were obtained from Gene Expression Omnibus(GEO), GeneCards, Online Mendelian Inheritance in Man(OMIM), and Therapeutic Target Database(TTD).

[Discussion on safety of Xanthii Fructus and consideration on its rational use].

Xanthii Fructus is a traditional Chinese medicine for the treatment of sinusitis and headache,rich in medicinal materials and is widely used for more than 1 800 years. Modern pharmacological studies have showed that Xanthii Fructus has anti-inflammatory,analgesic,anti-tumor,anti-bacterial,hypoglycemic,anti-allergic,immunomodulatory and other pharmacological effects,which can be commonly used in the treatment of diseases relating to immune abnormalities,such as rheumatoid arthritis,acute and chronic rhinitis,allergic rhinitis,and skin diseases,with a high medicinal value. Toxicological studies have shown that Xanthii Fructus poisoning can cause substantial damage to organs,such as the liver,kidney,and gastrointestinal tract,especially to liver.

[Medication rules of Professor Zhang Bing in treatment of skin itching based on data mining].

Skin itching is a subjective sensation that causes the desire to scratch. It is one of the most common clinical symptoms at department of dermatology, even the only complaint of dermatological patients, which seriously affects the quality life of patients. Therefore, based on the software of traditional Chinese medicine inheritance auxiliary platform, association rules and complex system entropy clustering were adopted to collect and analyze Zhang Bing's prescriptions for skin itching, and get the drug use frequency and the relationship between drugs.

The spectrum-effect relationship-a rational approach to screening effective compounds, reflecting the internal quality of Chinese herbal medicine.

Since the chromatographic fingerprint was introduced, it has been accepted by many countries to assess the quality and authenticity of Chinese herbal medicine (CHM). However, solely using the chromatographic fingerprint to assay numerous chemicals is not suitable for the assessment of the whole internal quality and pharmacodynamics of CHM. Consequently, it is necessary to develop a rational approach to connecting the chromatographic fingerprint with effective components to assess the internal quality of CHM.

[Molecular docking analysis of xanthine oxidase inhibition by constituents of cichory].

Human xanthine oxidase is considered to be a target for therapy of hyperuricemia. Cichorium intybus is a Chinese plant medicine which widely used in Xinjiang against various diseases. In order to screen the inhibitors of xanthine oxidase from C.

Relationship between High-Performance Liquid Chromatography Fingerprints and Uric Acid-Lowering Activities of Cichorium intybus L.

This study aimed to explore the spectrum-effect relationships between high-performance liquid chromatography fingerprints and the uric acid-lowering activities of chicory. Chemical fingerprints of chicory samples from ten different sources were determined by high-performance liquid chromatography, and then investigated by similarity analysis and hierarchical clustering analysis. Pharmacodynamics experiments were conducted in animals to obtain the uric acid-lowering activity information of each chicory sample.

[Mechanism of endogenous carbon monoxide effect on hydrogen sulfide in guinea pigs with established allergic rhinitis].

Objective: To study the effect of carbon monoxide (CO) on hydrogen sulfide (H2S) in guinea pigs with allergic rhinitis (AR) through intervention treatment.

Methods: AR model in guinea pigs was established by using ovalbumin. The animals were divided into three groups.
