Clinical study of abnormal glucose metabolism and insulin resistance in patients with liver cirrhosis.

Background: To investigate the correlation between abnormal glucose metabolism and insulin resistance in patients with liver cirrhosis.

Methods: A total of 254 participants were assigned into either the experimental group (EG) (n=123) or the normal group (NG) (n=131). We detected fasting blood glucose (FBG), postprandial blood glucose (PBG), fasting insulin (FINS), postprandial insulin, Hemoglobin A1c (HbA1c) and Insulin sensitivity index (ISI), at the same time, we compared various indexes in different Child-Pugh classification of the experimental group.

[Extraction and separation of flavonoids from leave of Eucommia ulmoides in aqueous two-phase system].

Objective: To optimize the aqueous two-phase extraction and separation technology of flavonoids from the leaves of Eucommia ulmoides.

Methods: The system was prepared by dissolving suitable amounis of polyethylene glycol 4000 (PEG4000) and dextran 40000 ( D40) in aqueous solution. Phase map of the system, the mass fraction of PEG4000 and D40, the effects of amount of added sample, pH value and temperature on target compounds were investigated systematically.
