Performance of novel multiparametric second-generation dual-layer spectral detector CT in gouty arthritis.

Objectives: This study aimed to compare the performance of different dual-energy computed tomography (DECT) technologies in detecting monosodium urate (MSU) crystals and evaluate the potential clinical value of novel second-generation dual-layer spectral detector CT (dlDECT) in gouty arthritis.

Methods: Using data collected from a tertiary hospital, we examined the diagnostic accuracy of different DECT technologies for the diagnosis of MSU. We used two standards: (1) demonstration of MSU crystals in synovial fluid (gold) and (2) 2015 ACR/EULAR gout classification criteria (silver).

Silicon composition and stoichiometric ratios with other nutrients in the lower Minjiang River, Southeast China.

Over the past decades, rivers have delivered imbalanced nutrient loads to coastal marine ecosystems due to human activities, which leads to serious regional or global eutrophication problems. The Minjiang River is heavily influenced by human activities. To understand the changing characteristics of nutrient transport ratios in the Minjiang River waters, we measured the seasonal variations of carbon, nitrogen, phosphorus and silicon nutrients in the lower surface waters of the Minjiang River between July 2019 and July 2020.

Artificial intelligence aided precise detection of local recurrence on MRI for nasopharyngeal carcinoma: a multicenter cohort study.

Background: MRI is the routine examination to surveil the recurrence of nasopharyngeal carcinoma, but it has relatively lower sensitivity than PET/CT. We aimed to find if artificial intelligence (AI) could be competent pre-inspector for MRI radiologists and whether AI-aided MRI could perform better or even equal to PET/CT.

Methods: This multicenter study enrolled 6916 patients from five hospitals between September 2009 and October 2020.

[Identification of active components of Dendrobium inhibit growth of gastric cancer cells based on component-activity relationship].

Three cancer cell lines including gastric cancer SGC-7901, HGC-27, and MGC-803 cells were employed to evaluate the bioactivity of seven Dendrobium species. Simultaneously, these Dendrobium species were assessed with UPLC-Q-TOF-MS, and 504 common peaks were found. Based on the hypothesis that biological effects varied with differences in components, multivariate relevance analysis for chemical component-activity relationship of Dendrobium, including grey relation(GRA) and partial least squares(PLS) analysis were performed to evaluate the contribution of each identified component.

Enhancement of epithelial cell autophagy induced by sinensetin alleviates epithelial barrier dysfunction in colitis.

Intestinal epithelial barrier dysfunction is a key pathology of colitis. Autophagy of epithelial cells maintains homeostasis of the intestinal barrier by inhibiting apoptosis and stimulating degradation of the tight junction protein claudin-2. This study investigated the effects and mechanism of activity of sinensetin, a polymethylated flavonoid isolated from tangerine peel and citrus, on intestinal barrier dysfunction in colitis.

Ethnopharmacological Relevance: Dragon's blood (Chinese name: Xuejie), which comprises red resins obtained from several plants (27 species from 4 families), is drawing worldwide interests in medicinal applications owing to its broad pharmacological spectrum such as promoting blood circulation, regenerating muscle, relieving swelling and pain, maintaining hemostasis, etc. AIM OF THE STUDY: This work aims to evaluate current research progress on phenolic constituents, pharmacological activities, quality control, and metabolism of six Dracaena plants, namely, Dracaena cochinchinensis (Lour.) S.

Diversity of culture-independent bacteria and antimicrobial activity of culturable endophytic bacteria isolated from different Dendrobium stems.

Dendrobium is known for its pharmacological actions including anti-cancer effect, anti-fatigue effect, gastric ulcer protective effect, and so on. At present, only studies on endophytic fungi of Dendrobium affecting the metabolites of host plants have been reported, very little research has been done on endophytic bacteria. In this study, we have demonstrated the great diversity of endophytic bacteria in 6 Dendrobium samples from different origins and cultivars.

[Identification of active components in Longxue Tongluo Capsules against ischemic brain injury based on component-activity relationship].

Modulation of staurosporine-activated volume-sensitive outwardly rectifying Cl⁻ channel by PI3K/Akt in cardiomyocytes.

Chloride (Cl⁻) channels participate in the regulation of cardiac function in response to stress although the underlying regulatory mechanism remains poorly understood. This study was designed to examine the impact of the pro-apoptotic stimulus staurosporine (STS) on the volume-sensitive outwardly rectifying Cl⁻ current (I(Cl,Vol)) in cardiomyocytes and possible regulatory mechanism involved with a focus on phosphatidylinositol-3 kinase (PI3K)/Akt. Primary cultured rat neonatal cardiomyocytes were subjected to hypotonic and isotonic environment in the presence or absence of STS prior to whole-cell voltage-clamp evaluation of Cl⁻ current.
