[Pharmacokinetics of Jinlingzi San and its single medicines in rats by LC-MS/MS].

This study aims to investigate the scientificity and efficacy of the compatibility of Jinlingzi San from pharmacokinetics. Liquid chromatography-tandem mass spectrometry(LC-MS/MS) was utilized to determine the plasma concentrations of the active components: toosendanin, tetrahydropalmatine A, and tetrahydropalmatine B at various time points following the gavage of Jinlingzi San and its single medicines in rats. Subsequently, WinNonlin was employed to calculate pertinent pharmacokinetic parameters.

[Influence of rhubarb on gastrointestinal motility and intestinal mucosal barrier in patients with severe burn].

Objective: To observe the influence of rhubarb on gastrointestinal motility and intestinal mucosal barrier in patients with severe burn.

Methods: Thirty patients with severe burn admitted to our burn wards within 48 hours after burn injury from December 2009 to December 2010 were divided into therapeutic group (T, treated with 10 g rhubarb by nasal feeding and 5 g L-glutamine by oral administration beginning from 6 hours after admission, three times per day, and also given enteral nutrition beginning from 24 hours after admission, n = 16) and control group (C, received the same treatment as used in T group but without rhubarb, n = 14) according to the random number table. Gastrointestinal function indexes including restoration of bowel sound within 24 hours, abdominal distension, tolerance to enteral nutrition, and defecation were observed after treatment.

[Spatial organization of neurons, astrocytes and vessels in rat brain].

Objective: To demonstrate the spatial organization of neurons, astrocytes and vessels in rat brain.

Methods: Cerebral vascular was shown by vivi-perfusion with ink. Glial fibrillary acidic protein (GFAP) immunohistochemistry and nissl's staining were performed on the serial sections of frozen brain tissues.
