Mechanistic Analysis and Process Simulation of Ethyl Acetate-Ethanol Separation by Complex Solvent Extractive Distillation.

Developing high-performance solvents for extraction and optimizing process technologies is crucial for efficient extractive distillation (ED) separation of azeotrope mixtures. In this paper, computer-aided screening was used to study the ED of azeotrope mixtures in ethyl acetate and ethanol systems using organic solvent dimethyl sulfoxide (DMSO) and ionic liquid (IL) ([EMIM][Ac]). The structural relationship between the ILs and the azeotrope mixture was analyzed by σ-profile, molecular surface electrostatic potential, interaction energy, and separation gradient.

Alteration of serum bile acid profiles of HBV-related hepatocellular carcinoma identified by LC-MS/MS.

Background: Hepatocellular carcinoma closely related to metabolic disorders is a common and aggressive liver malignancy. The dysregulation of bile acid homeostasis has emerged as a key factor for the development and progression of HCC. We aimed to investigate the relationship between bile acids and HCC diagnosis and progression.

[The combined application of scalp and body acupuncture by stages for low limb dysfunction of patients with apoplexy].

Objective: To verify the clinical efficacy on the function recovery of lower extremities for patients with cerebral apoplexy by the staging treatment with the combined therapy of the scalp and body acupuncture.

Methods: Ninty-six cases were randomized into an observation group and a control group, 48 cases in each one. The conventional medication and rehabilitation therapy were given in each group.
