Inflammation regulation is essential for maintaining healthy functions and normal homeostasis of the body. Porphyromonas gingivalis (P. gingivalis) is a gram-negative anaerobic bacterium and a major pathogen that causes oral inflammation and other systemic inflammations. This study aims to examine the anti-inflammatory effects of Agrimonia pilosa Ledeb root extracts (APL-ME) in Porphyromonas gingivalis LPS-induced RAW 264.7 cells and find anti-inflammatory effect compounds of APL-ME. ⋯ However, IL-10 expression was increased by ALP-ME. In addition, protein expressions of COX-2 and iNOS were inhibited APL-ME extracts dose-dependently. According to these results, APL-ME has anti-inflammatory effects in P. gingivalis LPS induced RAW 264.7 cells.

Macrophage autophagy defect is closely related to the progression of atherosclerosis (AS) and is regulated by the triggering receptor expressed on myeloid cell 2 (TREM2). TREM2 is a key factor in the development of Alzheimer's disease (AD), the deficiency of which leads to anomalous autophagy in microglia. However, the role of TREM2 in the autophagy of plaque macrophages is still unclear. ⋯ GP inhibited the progression of AS in ApoE[Formula: see text] mice, reinforced macrophage autophagy, and downregulated TREM2 by inhibiting mTOR signaling. Taken together, augmenting the autophagy levels in plaque macrophages by inhibiting the TREM2/mTOR axis can potentially impede atherosclerotic progression. The promising therapeutic effects of GP seen in this study should be validated in future trials, and the underlying mechanisms have to be elucidated in greater detail.

Meta Analysis
Efficacy and Safety of Ginkgo biloba in Patients with Acute Ischemic Stroke: A Systematic Review and Meta-Analysis.
Ginkgo biloba and its extract have been suggested to have a neuroprotective role in patients with acute ischemic stroke. We aimed to examine the efficacy and safety of Ginkgo biloba use in patients with acute ischemic stroke. We searched seven databases for randomized controlled studies examining the use of Ginkgo biloba in patients with acute ischemic stroke. ⋯ There was no apparent impact of Ginkgo biloba use on all-cause mortality (Risk ratio (RR): 1.21; 0.29-5.09, p=0.80) or cerebrovascular bleeding (RR: 0.82; 0.43-1.57, p=0.55). There was limited evidence on to support the use of gingko biloba in terms of improving quality of life and other stroke events. As such, more studies are needed before it can be recommended for routine use in improving neurological and cognitive function in patients with acute ischemic stroke.

Review Historical Article
Potential Targets for Treatment of Coronavirus Disease 2019 (COVID-19): A Review of Qing-Fei-Pai-Du-Tang and Its Major Herbs.
COVID-19 has been declared a pandemic by WHO on March 11, 2020. No specific treatment and vaccine with documented safety and efficacy for the disease have been established. Hence it is of utmost importance to identify more therapeutics such as Chinese medicine formulae to meet the urgent need. ⋯ Two clusters of actions identified were cytokine storm prevention and angiotensin converting enzyme 2 (ACE2) receptor binding regulation. The multi-target mechanisms of QFPDT for treating viral infection in general and COVID-19 in particular were validated. While large scale clinical studies on QFPDT are being conducted in China, one should use real world data for exploration of integrative treatment with inclusion of pharmacokinetic, pharmacodynamic and herb-drug interaction studies.

Chinese Herbal Medicines (CHM) are the most common interventions of traditional Chinese medicine (TCM), typically administered as either single herbs or formulas. Systematic reviews (SRs) are essential references for evaluating the efficacy and safety of CHM treatments accurately and reliably. Unfortunately, the reporting quality of SRs with CHM is not optimal, especially the reporting of CHM interventions and the rationale of why these interventions were selected. ⋯ A total of twenty-four items (including sub-items) are included in the checklist, relating to title (1), structured summary (2), rationale (3), objectives (4), eligibility criteria (6), data items (11), synthesis of results (14, 21), additional analyses (16, 23), study characteristics (18), summary of evidence (24), and conclusions (26). Illustrative examples and explanations are also provided. The group hopes that PRISMA-CHM 2020 will improve the reporting quality of SRs of CHM.
