RESUMO
@#Abstract: The coronavirus disease 2019 (COVID-19) has become a global public health problem due to its highly contagious nature. This article aims to discuss the current situation of traditional Chinese medicine in the prevention and treatment of COVID-19, and to provide a basis for traditional Chinese medicine research and scientific and standardized treatment of COVID-19.In this article, the etiology, pathogenesis, treatment plan and research progress were summarized, analyzed and concluded by retrieving and reviewing the literature and clinical reports related to the prevention and treatment of COVID-19 with traditional Chinese medicine. Traditional Chinese medicine has obvious effects in the prevention and treatment of COVID-19, improvement of clinical symptoms, and control of disease progression, which had the unique advantages of mild curative efficacy and safety. It has important practical significance in relieving patients' early symptoms and reducing the incidence of progression from mild to severe, and had great potential for development in the treatment of COVID-19. The traditional Chinese medicine intervention and the formulation of diagnosis and treatment plans for the COVID-19 need to be continuously optimized and improved. Scientific and rational application of traditional Chinese medicine to prevent and treat COVID-19, optimization diagnosis and treatment programs, and in-depth exploration of pharmacological mechanisms, especially the provide reference for early intervention of new coronavirus pneumonia by traditional Chinese medicine, the control of disease progression in the middle stage, and improve prognosis in the late stage with Western medicine.
RESUMO
AIMS/INTRODUCTION: To explore relationships between polyunsaturated fatty acids (PUFA) and non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes, and whether insulin action has an interactive effect with PUFA on NAFLD progression. MATERIALS AND METHODS: We extracted clinical and omics data of 482 type 2 diabetes patients from a tertiary hospital consecutively from April 2018 to April 2019. NAFLD was estimated by ultrasound at admission. Plasma fasting n3 and n6 fatty acids were quantified by liquid chromatography-tandem mass spectrometry analysis. Restricted cubic spline nested in binary logistic regression was used to select the cut-off point, and estimate odds ratios and 95% confidence intervals. Additive interactions of the n6 : n3 ratio with insulin action for NAFLD were estimated using relative excess risk due to interaction, attributable proportion due to interaction and synergy index. Relative excess risk due to interaction >0, attributable proportion due to interaction >0 or synergy index >1 indicates biological interaction. Spearman correlation analysis was used to obtain partial correlation coefficients between PUFA and hallmarks of NAFLD. RESULTS: Of 482 patients, 313 were with and 169 were without NAFLD. N3 ≥800 and n6 PUFA ≥8,100 µmol/L were independently associated with increased NAFLD risk; n6 : n3 ratio ≤10 was associated with NAFLD (odds ratio 1.80, 95% confidence interval 1.20-2.71), and the effect size was amplified by high C-peptide (odds ratio 8.89, 95% confidence interval 4.48-17.7) with significant interaction. The additive interaction of the n6 : n3 ratio and fasting insulin was not significant. CONCLUSION: Decreased n6 : n3 ratio was associated with increased NAFLD risk in type 2 diabetes patients, and the effect was only significant and amplified when there was the co-presence of high C-peptide.
