Meta Analysis Comparative Study
Herbal Medicine Treatment for Influenza: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
The aim of this research is to evaluate the clinical evidence of an herbal medicine (HM) treatment on influenza and describe the potential benefits and adverse events by reviewing all relevant randomized controlled trials. All papers published from 2010 to 2019 in all languages in six databases were searched, including all randomized controlled trials on adults and children, testing herbal medicine for treatment of influenza, alone or in combination with conventional antiviral therapy. The main outcome parameters of interest were total effective rate, time to resolution of fever, adverse events, complications, and duration of viral shedding. 25 trials of 3044 patients were included. ⋯ HM presented fewer adverse events compared to oseltamivir, but the difference was not significant (risk difference, [Formula: see text]0.04; 95% CI, [Formula: see text]0.09 to 0.00; [Formula: see text]), and the combined treatment did not increase adverse events compared to oseltamivir (risk difference, [Formula: see text]0.02; 95% CI, [Formula: see text]0.06 to 0.02; [Formula: see text]). Research findings show that herbal medicine treatments have beneficial therapeutic effects on influenza and could decrease duration of fever and improve total effective rate. In addition, herbal medicine plus oseltamivir combined therapy could increase the therapeutic effect compared to a single treatment with oseltamivir.

Diabetes mellitus is a chronic endocrine disease result from absolute or relative insulin secretion deficiency, insulin resistance, or both, and has become a major and growing public healthy menace worldwide. Currently, clinical antidiabetic drugs still have some limitations in efficacy and safety such as gastrointestinal side effects, hypoglycemia, or weight gain. ⋯ A great deal of pharmacological research showed that rosemary extract and its phenolic constituents, especially carnosic acid, rosmarinic acid, and carnosol, could significantly improve diabetes mellitus by regulating glucose metabolism, lipid metabolism, anti-inflammation, and anti-oxidation, exhibiting extremely high research value. Therefore, this review summarizes the pharmacological effects and underlying mechanisms of rosemary extract and its primary phenolic constituents on diabetes and relative complications both in vitro and in vivo studies from 2000 to 2020, to provide some scientific evidence and research ideas for its clinical application.

In December 2019, coronavirus disease-2019 (COVID-19) broke out in Wuhan and other places. Seven versions of the Diagnosis and Treatment Program for Coronavirus Disease-2019 successively issued by the Chinese government have designated traditional Chinese medicine (TCM) as a necessary medical strategy. Based on the changes in TCM diagnosis and treatment strategies in these seven versions of Diagnosis and Treatment Program for Coronavirus Disease-2019, this paper collected data reported by the Chinese government media; analyzed the understanding of the etiology, pathogenesis, syndrome differentiation, treatment methods, and prescriptions of COVID-19 by TCM and evaluated the clinical efficacy of TCM strategies. ⋯ TCM strategies represented by Qing Fei Pai Du Tang have shown apparent advantages in improving symptoms, promoting virus clearance, and shortening hospitalization, as well as surprising efficacy of zero patient progressing from mild to severe cases in a TCM cabin hospital. Clinical data illustrate the effectiveness of TCM strategies proposed by the Chinese government. This major epidemic may bring new opportunities for TCM development.

Depression is partially caused by inflammation in the central nervous system. Early study demonstrated that musk, glandular secretion from male musk deer, exerted an antidepressant-like effect. The aim of this study was to investigate if muscone, a bioactive ingredient in musk, could ameliorate neuroinflammation and depressive-like behaviors as well as explore the potential action mechanism. ⋯ LPS-induced activation of microglial cells and elevation in expression of inflammatory cytokines including IL-1 β , RANTES, and MCP-1 in the prefrontal cortex of mice were effectively abrogated by muscone, which significantly down-regulated expression of TLR4, MyD88, Caspase-1, NLRP3, renin, and Ang II. In addition, treatment of BV2 microglia cells with muscone markedly attenuated the LPS-induced rise in protein expression of TLR4, Ang II, and IL-1 β. This study revealed that muscone could ameliorate LPS-induced depressive-like behaviors by repressing neuroinflammation in the prefrontal cortex of mice caused by its suppression on microglia activation and production of inflammatory cytokines via acting on TLR4 pathway and RAS cascade.

The outbreak caused by COVID-19 is causing a major challenge to clinical management and a worldwide threat to public health. So far, there is no specific anti-coronavirus therapy approved for the treatment of COVID-19. Recently, as the efficacy and safety of traditional Chinese medicine (TCM) is widely acknowledged, it has been brought to a crucial status by the public, governments, and World Health Organization (WHO). ⋯ Therefore, on the basis of epidemiology and virology information, we reviewed relevant meta-analysis and clinical studies of anti-coronavirus therapeutics by TCM, in the aspect of mortality, symptom improvement, duration and dosage of corticosteroid, incidence of complications and the like. In addition, we also summarized preclinical rationale for anti-coronavirus activity by TCM in terms of virion assembly and release, as well as viral entry and replication, which could be a useful contribution for figuring out effective Chinese herbal medicine (CHM) for coronavirus, including ingredients from single monomeric compounds, Chinese herbs, Chinese herb extracts and Chinese herb formulas, or potential targets for medicine. We would like to see these relevant studies, ranging from basic researches to clinical application, could provide some idea on effects of CHM to combat COVID-19 or other coronaviruses, and also offer new thinking for the exploration of therapeutic strategies under the guidance of TCM.
