Natural soluble epoxide hydrolase inhibitors from Inula britanica and their potential interactions with soluble epoxide hydrolase: Insight from inhibition kinetics and molecular dynamics.

Soluble epoxide hydrolase (sEH) is a potential drug target to treat inflammation and neurodegenerative diseases. In this study, we found that the extract of Inula britanica exhibited significantly inhibitory effects against sEH, therefore, we investigated its phytochemical constituents to obtain seven new compounds together with sixteen known ones (1-20), including two pairs of novel enantiomers, (2S,3S)-britanicafanin A (1a), (2R,3R)-britanicafanin A (1b), (2R,3S)-britanicafanin B (2a), and (2S,3R)-britanicafanin B (2b), and three new lignans britanicafanins C-E (3-5). Their structures were determined by HRESIMS, 1D and 2D NMR, and electronic circular dichroism (ECD) spectra as well as quantum chemical computations.

Prognostic value of serum amyloid A in patients with COVID-19.

Objective: To investigate the prognostic value of serum amyloid A (SAA) in the patients with Corona Virus Disease 2019 (COVID-19).

Methods: The medical data of 89 COVID-19 patients admitted to Renmin Hospital of Wuhan University from January 3, 2020 to February 26, 2020 were collected. Eighty-nine cases were divided into survival group (53 cases) and non-survival group (36 cases) according to the results of 28-day follow-up.

Natural sesquiterpenoid oligomers: A chemical perspective.

Sesquiterpenoid oligomers, biogenetically assembled by at least two monomeric sesquiterpenoid units via diverse pathways, represent a unique class of natural products with distinct bioactivities. Herein, we provide a review covering the dimeric, trimeric, and tetrameric sesquiterpenoids categorized by reaction types in biosynthesis from a chemical perspective. Emphasis is focused on the biosynthetic oligomerization pathways of these interesting molecules and their related biological functions, which will supply inspiration for the total synthesis or biomimetic synthesis of more oligomeric sesquiterpenoids and further pharmacological investigations.

Effect of kai xin san on learning and memory in a rat model of paradoxical sleep deprivation.

The present study aimed to evaluate the effect of kai xin san (KXS, at doses of 500, 250, and 125 mg/kg body weight per day), a well-known traditional Chinese medicine, on learning and memory in paradoxical sleep deprivation (PSD)-induced cognition deficit rats. Two behavior tests (the Open Field test and the Morris water maze task) were used for testing the effects of KXS on a PSD-induced learning and memory deficit model. Furthermore, its effect on the glutamic acid (GLU) and γ-amino-butyric acid (GABA) levels in the brain tissue, brain-derived neurotrophic factor (BDNF), cyclic AMP response element binding protein (CREB), and phosphorylated-CREB (p-CREB) expression in the hippocampus was also tested.

[Effect and mechanism of dingzhixiao wan on scopolamine-induced learning-memory impairment in mice].

Objective: To investigate the effect of Dingzhixiao Wan (DZXW), a classic traditional Chinese medicine formula consisting of Acorus tatarinowii, Polygala tenuifolia, Poria cocos and Panax ginseng in a proportion of 2: 2: 3: 3, on learning-memory impairment induced by scopolamine and its possible mechanisms.

Method: The mice were randomly divided into six groups: the control group, the model group, the positive huperzine A (0.05 mg x kg(-1)) group, DZXW 700 mg x kg(-1), 350 mg x kg(-1) and 175 mg kg(-1) groups.

[Predictive value of corrected QT interval, corrected Tp-e interval and Tp-e/QT ratio on malignant arrhythmia events in acute ST-segment elevation myocardial infarction patients undergoing thrombolysis].

Objective: The prognostic value of corrected QT interval (QTc), corrected Tp-e interval (Tp-ec) and Tp-e/QT ratio on occurrence of malignant arrhythmia events (MAE) in acute ST-segment elevation myocardial infarction (STEMI) patients underwent successful thrombolysis was explored and the potential association of these indices with MAE was analyzed.

Methods: Fifty-seven STEMI patients underwent successful thrombolytic therapy within 6 hours after admission and conservative medical treatment were included. QTc, Tp-ec, Tp-e/QT ratio were obtained and calculated in infarct-related electrocardiograph leads and non-infarct-related leads before thrombolysis, (7±1) days and (30±3) days after thrombolysis respectively, and incidence of MAE up to 30 days after thrombolysis was analyzed.

Antidepressant-like effect of the extracted of Kai Xin San, a traditional Chinese herbal prescription, is explained by modulation of the central monoaminergic neurotransmitter system in mouse.

Ethnopharmacological Relevance: Kai Xin San (KXS) is a traditional Chinese herbal prescription for the treatment of depression-like disorders, anxiety, and impairment in learning and memory, however, there is very little scientific data concerning the efficacy of this.

Aim Of The Study: The present study aimed to investigate the antidepressant potential of Kai Xin San and its possible mechanisms.

Materials And Methods: Mouse models of depression including the tail suspension test (TST) and the forced swim test (FST) were used to evaluate the effects of KXS.

[The clinical epidemiology characteristics of HFMD in 2010 of Hangzhou].

Aim: To study the expression of ether à go-go (Eag1) potassium channel in colorectal cancer and the relation-ship between their expression and clinico-pathological features.

Methods: The expression levels of Eag1 protein were determined in 76 cancer tissues with paired non-cancerous matched tissues as well as 9 colorectal adenoma tissues by immunohistochemistry. Eag1 mRNA expression was detected in 13 colorectal cancer tissues with paired non-cancerous matched tissues and 4 colorectal adenoma tissues as well as two colorectal cancer cell lines (LoVo and HT-29) by reverse transcription PCR.
