Comparative Analysis of the Wounded in Patients and Deaths in a Hospital Following the Three Major Earthquakes in Western China.

The purpose of this study was to analyze the injury characteristics of patients and therapeutic strategies for patients injured in the last three big earthquakes in China, so as to provide a reference for the improvement of emergency plans for earthquakes. The analysis was based on the data provided by the Mianyang Central Hospital (MCH) from May 12th, 2008 to September 26th, 2017. Microsoft EXCEL software was used for data input, and SPSS was used for statistical analysis.

Determination of oroxylin A, oroxylin A 7-O-glucuronide, and oroxylin A sodium sulfonate in beagle dogs by using UHPLC MS/MS Application in a pharmacokinetic study.

Oroxylin A, obtained from the root of Scutellaria baicalensis Georgi, is a flavonoid with antitumor and other pharmacological activities. Our previous studies showed for the first time that it is mainly metabolized to oroxylin A sodium sulfonate by sulfotransferase enzymes in beagle dogs. In this study, rapid, universal, selective, and robust ultra-high-performance liquid chromatography-tandem mass spectrometry methods were established and fully validated to quantitatively detect oroxylin A, oroxylin A 7-O-glucuronide, and oroxylin A sodium sulfonate in beagle dog plasma.

Pharmacokinetics, tissue distribution and excretion study of Oroxylin A, Oroxylin A 7-O-glucuronide and Oroxylin A sodium sulfonate in rats after administration of Oroxylin A.

Oroxylin A (OA), as a natural flavonoid extracted from the root of Scutellaria baicalensis Georgi, is a candidate drug with multiple pharmacological activities. However, pharmacokinetic studies of OA have rarely been reported up to now. The present study aim to conduct a systemic evaluation on the pharmacokinetics, tissue distribution and excretion of OA in rats, with quantification of both OA and its two metabolites, Oroxylin A 7-O-glucuronide (OG) and Oroxylin A sodium sulfonate (OS) by the sensitive and rapid UPLC-MS/MS methods.

Oroxylin A, a methylated metabolite of baicalein, exhibits a stronger inhibitory effect than baicalein on the CYP1B1-mediated carcinogenic estradiol metabolite formation.

Human cytochrome P450 1B1 (CYP1B1)-mediated formation of 4-hydroxyestradiol (4-OHE2) from 17β-estradiol plays an important role in the progression of human breast cancer, while the biotransformation of 17β-estradiol to 2-hydroxyestradiol mediated by cytochrome P450 1A1 (CYP1A1) is considered as a less harmful pathway. In this study, inhibitory effects of flavonoids baicalein and oroxylin A, a metabolite of baicalein in human body, on CYP1A1 and 1B1 activities were investigated in vitro. The inhibition intensities of baicalein and oroxylin A towards CYP1B1 were greater than towards CYP1A1 with a mixed mechanism.

[Injury characteristics and therapeutic strategy of patients injured in "8·8" Jiuzhaigou earthquake].

Objective: To summarize the injury characteristics and therapeutic strategy of patients injured in "8·8" Jiuzhaigou earthquake.

Methods: The clinical data of 48 patients injured in "8·8" Jiuzhaigou earthquake who were admitted to Mianyang Central Hospital were analyzed retrospectively. There were 25 males and 23 females with an average age of 36 years (range, 5-87 years).

Determination of oroxylin A and oroxylin A 7-O-d-glucuronide in HepG2 cell lysate and subcellular fractions with SPE-UPLC-MS/MS: Cellular pharmacokinetic study to indicate anti-cancer mechanisms.

Targeting therapy of anti-cancer drugs has been gaining increasing attention. Cell pharmacokinetics have been used for in vitro disposition evaluation, as well as drug-drug interaction for anti-cancer drugs, revealing their fate after entering tumor. Flavonoid compound oroxylin A (OA) possesses strong anti-cancer effects especially on the liver and breast cancer.

[Impact of anxiety-depression symptoms on clinical recovery and serum TNF-alpha and IL-6 of patients with burns].

Objective: To investigate the impact of anxiety-depression symptoms on the healing of burn wounds and the serum tumor necrosis factor a (TNF-alpha) and interleukin-6 (IL-6) in the patients with moderate and severe burns.

Methods: The patients with moderate and severe burns were divided into anxiety-depression group (24 patients) and non-anxiety-depression group (27 patients)according to the scores of anxiety-depression scores three days after burn measured by Hamilton Rating Scale for Depression (HAMD) and Hamilton Rating Scale for Anxiety (HAMA). The routine therapy was applied for both groups for 30 days.
