Baicalin confers hepatoprotective effect against alcohol-associated liver disease by upregulating microRNA-205.

Recently, baicalin refers to flavonoid compound extracted from Scutellaria baicalensis Georgi has been indicated to hold promising therapeutic effects in alcohol-associated liver disease (ALD). However, knowledge of the molecular mechanisms for its hepatoprotective effect is still very limited. Evidence exists suggesting potential association between miR-205 and baicalin's function. Bioinformatic analysis and dual luciferase reporter assay were conducted to determine the binding affinity between miR-205 and importinα5. Our findings revealed that baicalin could alleviate ALD by raising the expression of miR-205. Additionally, miR-205 repressed NF-κB signaling pathway activation by binding to importinα5 to relieve ALD. Baicalin inhibited importinα5-mediated NF-κB signaling pathway to protect the liver against alcohol-induced injury, inflammation, oxidative stress and hepatocyte apoptosis. Taken conjointly, baicalin confers hepatoprotective effect against ALD through miR-205-mediated importinα5 inhibition via the NF-κB signaling pathway, highlighting a promising therapeutic target for ALD treatment with the help of traditional Chinese medicine.

Chemical profiling of Callicarpa nudiflora and its effective compounds identification by compound-target network analysis.

Callicarpa nudiflora, belonging to the family Verbenaceae, is widely used to treat inflammation caused by bacterial infection.However, the underlying active substances of C. nudiflora against inflammation remains obscure. In this work, an ultra high-performance liquid chromatography (UHPLC) coupled with quadrupole time-of-flight mass spectrometry method was developed to characterize the ingredients in C. nudiflora, and a validated UHPLC coupled with triple quadrupole tandem mass spectrometry method was applied to quantify major components. As a result, a total of 96 chemical compounds were identified in C. nudiflora, and 26 compounds of them were further quantified in 34 batches of C. nudiflora. Based on the identified components from C. nudiflora, a compound-target network for the anti-inflammation effect was constructed by reverse docking target prediction, disease associated genes screening in DisGeNET and the protein-protein interaction from STRING. The compound-target network showed that C. nudiflora might exert anti-inflammation effect on the target of complement 3 and 5 in the pathway of cells and molecules involved in local acute inflammatory response, and 16 effective candidate compounds were found such as catalpol, acteoside, rutin, etc. This study provided an opportunity to deepen the understanding of the chemical composition and the potential anti-inflammatory mechanism of C. nudiflora.

Acupuncture on treating asthma: A protocol for systematic review and meta analysis.

BACKGROUND: Asthma is one of the most common chronic diseases in the world, with approximately 300 million asthma patients worldwide. The mortality rate of asthma is 1.6 to 36.7 / 100,000 people, and China has become one of the countries with the highest asthma death rate in the world. Asthma is a chronic allergic airway inflammatory disease. Patients with this disease may have symptoms such as cough, wheezing, and difficulty breathing. For many years, Western medicine has mainly used anti-inflammatory, anti-bronchial spasm, asthma, cough and oxygen to treat this disease, but the effect is not good. Clinical studies in recent years have found that the use of acupuncture in the treatment of bronchial asthma has a good clinical application prospect. This study was conducted to study the effect of using acupuncture to treat asthma. METHODS AND ANALYSIS: We will search for PubMed, Cochrane Library, AMED, EMbase, WorldSciNet; Nature, Science online and China Journal Full-text Database (CNKI), China Biomedical Literature CD-ROM Database (CBM), and related randomized controlled trials included in the China Resources Database. The time is limited from the construction of the library to November 2019. We will use the criteria provided by Cochrane 5.1.0 for quality assessment and risk assessment of the included studies, and use the Revman 5.3 and Stata13.0 software for meta-analysis of the effectiveness, recurrence rate, and symptom scores of asthma. ETHICS AND DISSEMINATION: This systematic review will evaluate the efficacy and safety of acupuncture for asthma. Because all of the data used in this systematic review and meta-analysis has been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process Trial.

Therapeutic outcomes of combined topical autologous serum eye drops with silicone-hydrogel soft contact lenses in the treatment of corneal persistent epithelial defects: A preliminary study.

PURPOSE: To evaluate the efficacy of the combination of topical 20% autologous serum eye drops (ASEs) and silicone-hydrogel soft contact lenses (SCLs) for the treatment of corneal persistent epithelial defects (PEDs), and to compare the recurrence of epithelial breakdown with or without continuous use of ASEs after silicone-hydrogel SCLs removal. METHODS: We conducted a prospective interventional study of 21 eyes of 21 patients with PEDs treated with combined ASEs and silicone-hydrogel SCLs from September 2014 to August 2015. SCLs were removed after total re-epithelialization and patients were subsequently randomized divided into two groups: (1) with and (2) without continuous use of ASEs for an additional 2 weeks. PEDs healing rate and epithelial defect recurrence were evaluated. RESULTS: PEDs healed in all eyes within 3 weeks. Recurrence was noted in five eyes (50%) in patients without continued use of ASEs for 2weeks after total re-epithelialization and SCLs removal during a 3-month follow-up (odds ratio: 23.0; P<0.05). Recurrent epithelial defects were successfully treated with secondary SCLs application combined with autologous serum use. No adverse events were noted during the entire treatment period. CONCLUSIONS: The combined use of ASEs and silicone-hydrogel SCLs can successfully treat recalcitrant PEDs. Prolonged use of ASEs after total re-epithelialization can decrease recurrence rates.

Saxagliptin is similar in glycaemic variability more effective in metabolic control than acarbose in aged type 2 diabetes inadequately controlled with metformin.

This study compared the effects on glycaemic variability and glucose control between saxagliptin and acarbose as add-on therapies for aged T2DM inadequately controlled with metformin alone. The results showed that compared with acarbose-metformin, saxagliptin-metformin was more effective in glucose control with similar glycaemic variability.

Clinical trial with traditional Chinese medicine intervention ''tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'' for chronic hepatitis B-associated liver failure.

AIM: To study the clinical efficacy of traditional Chinese medicine (TCM) intervention "tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment" ("TTK") for treating liver failure due to chronic hepatitis B. METHODS: We designed the study as a randomized controlled clinical trial. Registration number of Chinese Clinical Trial Registry is ChiCTR-TRC-12002961. A total of 144 patients with liver failure due to infection with chronic hepatitis B virus were enrolled in this randomized controlled clinical study. Participants were randomly assigned to the following three groups: (1) a modern medicine control group (MMC group, 36 patients); (2) a "tonifying qi and detoxification" ("TQD") group (72 patients); and (3) a "tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment" ("TTK") group (36 patients). Patients in the MMC group received general internal medicine treatment; patients in the "TQD" group were given a TCM formula "tonifying qi and detoxification" and general internal medicine treatment; patients in the "TTK" group were given a TCM formula of "TTK" and general internal medicine treatment. All participants were treated for 8 wk and then followed at 48 wk following their final treatment. The primary efficacy end point was the patient fatality rate in each group. Measurements of various virological and biochemical indicators served as secondary endpoints. The one-way analysis of variance and the t-test were used to compare patient outcomes in the different treatment groups. RESULTS: At the 48-wk post-treatment time point, the patient fatality rates in the MMC, "TQD", and "TTK" groups were 51.61%, 35.38%, and 16.67%, respectively, and the differences between groups were statistically significant (P < 0.05). However, there were no significant differences in the levels of hepatitis B virus DNA or prothrombin activity among the three groups (P > 0.05). Patients in the "TTK" group had significantly higher levels of serum total bilirubin compared to MMC subjects (339.40 µmol/L ± 270.09 µmol/L vs 176.13 µmol/L ± 185.70 µmol/L, P = 0.014). Serum albumin levels were significantly increased in both the "TQD" group and "TTK" group as compared with the MMC group (31.30 g/L ± 4.77 g/L, 30.72 g/L ± 2.89 g/L vs 28.57 g/L ± 4.56 g/L, P < 0.05). There were no significant differences in levels of alanine transaminase among the three groups (P > 0.05). Safety data showed that there was one case of stomachache in the "TQD" group and one case of gastrointestinal side effect in the "TTK" group. CONCLUSION: Treatment with "TTK" improved the survival rates of patients with liver failure due to chronic hepatitis B. Additionally, liver tissue was regenerated and liver function was restored.
