Medication Rules in Herbal Medicine for Mild Cognitive Impairment: A Network Pharmacology and Data Mining Study.

Background: Although traditional Chinese medicine (TCM) has good efficacy in the treatment of mild cognitive impairment (MCI), especially memory improvement and safety, its substance basis and intervention mechanism are particularly complex and unknown. Therefore, based on network pharmacology and data mining, this study aims to explore the rules, active ingredients and mechanism of TCM in the treatment of MCI.

Methods: By searching the GeneCard, OMIM, DisGeNET and DrugBank databases, we obtained the critical targets associated with MCI.

Xinglou Chengqi Decoction improves neurological function in experimental stroke mice as evidenced by gut microbiota analysis and network pharmacology.

The current study was designed to explore the brain protection mechanism of Xinglou Chengqi Decoction (XCD) based on gut microbiota analysis and network pharmacology. A transient middle cerebral artery occlusion (MCAO) model of mice was established, followed by behavioral evaluation, TTC and TUNEL staining. Additionally, to investigate the effects of gut microbiota on neurological function after stroke, C57BL/6 mice were treated with anti-biotic cocktails 14 days prior to ischemic stroke (IS) to deplete the gut microbiota.

Tongluo Huatan capsule improves cognitive function by regulating the endocytosis of N-methyl-D-aspartic acid receptors mediated by clathrin in a rat model of vascular dementia.

Objective: To explore the neuroprotective mechanisms of Tongluo Huatan capsule (THC) in a rat model of vascular dementia (VD).

Methods: A rat model of VD was established by repeated clamping of bilateral common carotid arteries with the intraperitoneal injection of sodium nitroprusside solution. VD rats were administered THC, memantine hydrochloride, or distilled water daily for 14 d after operation.

Therapeutic Targets and Mechanism of Xingpi Jieyu Decoction in Depression: A Network Pharmacology Study.

Background: Depression is a common mental disease that lacks effective therapeutic drugs with good curative effects and few adverse reactions. Traditional Chinese medicine (TCM) has the advantages of multiple components, multiple channels, and fewer adverse reactions in the treatment of depression. Although Xingpi Jieyu Decoction (XPJYD) demonstrates a good therapeutic effect on depression, the pharmacological mechanism underlying its antidepressant effect is still unclear.

[Systematic evaluation and Meta-analysis of efficacy and safety of Tianzhi Granules in treatment of vascular cognitive impairment].

Tianzhi Granules has effects in calming liver wind, nourishing liver and kidney and activating blood. At present, it is used for treatment of vascular cognitive impairment. However, its efficacy and safety remained to be verified.

McMYB12 Transcription Factors Co-regulate Proanthocyanidin and Anthocyanin Biosynthesis in Malus Crabapple.

The flavonoid compounds, proanthocyanidins (PAs), protect plants from biotic stresses, contribute to the taste of many fruits, and are beneficial to human health in the form of dietary antioxidants. In this study, we functionally characterized two Malus crabapple R2R3-MYB transcription factors, McMYB12a and McMYB12b, which co-regulate PAs and anthocyanin biosynthesis. McMYB12a was shown to be mainly responsible for upregulating the expression of anthocyanin biosynthetic genes by binding to their promoters, but to be only partially responsible for regulating PAs biosynthetic genes.

The Balance of Expression of Dihydroflavonol 4-reductase and Flavonol Synthase Regulates Flavonoid Biosynthesis and Red Foliage Coloration in Crabapples.

Red leaf color is an attractive trait of Malus families, including crabapple (Malus spp.); however, little is known about the molecular mechanisms that regulate the coloration. Dihydroflavonols are intermediates in the production of both colored anthocyanins and colorless flavonols, and this current study focused on the gene expression balance involved in the relative accumulation of these compounds in crabapple leaves.

A possible role of myristoylated alanine-rich C kinase substrate in endocytic pathway of Alzheimer's disease.

It is believed that amyloid-beta peptide (Abeta) plays a central role in the pathogenesis of Alzheimer's disease (AD). Thus, the process of amyloid precursor protein (APP) cleavage is a key event and has raised much attention in the field of AD research. It is proposed that APP, beta- and gamma-secretases are all located on the lipid raft, and the meeting of them is an indispensable step for Abeta generation.

[Regulation function of Qingnao drop pilula to MARCKS mRNA express changes in acute cerebral ischemia hippocampus].

Objective: To observe the contribution of Qingnao drop pilula to the alteration of myristoylated alanine-rich C kinase substrate (MARCKS) mRNA expression in acute multi-infarction hippocampus.

Method: Rat models of acute multi-infarction were established by injecting the embolus of blood powder through the right external carotid arteryinto the internal carotid artery, rats were randomly divided into five groups (n = 12 in each): normal, sham operation, model, Chinese medicine treatment, and Western medicine treatment. Qingnao drop pilula (133.
