Chromatographic adsorption of serum albumin and antibody proteins in cryogels with benzyl-quaternary amine ligands.

The preparation and characterization of mixed-mode adsorbents for a typical separation purpose are of great importance in bioseparation areas. In this work, we prepared a new monolithic cryogel with a combination of ion-exchange and hydrophobic functions by employing benzyl-quaternary amine groups. The fundamental cryogel properties, protein equilibrium adsorption isotherm and chromatographic adsorption in the cryogel were measured experimentally.

[Early clinical research of total hip arthroplasty for the treatment of old acetabular fractures].

Objective: To analyze the early clinical effects of total hip arthroplasty(THA) for the treatment of old acetabular fractures.

Methods: From January 2007 to June 2010, thirteen patients with old acetabular fractures were reviewed, including 10 males and 3 females. Ten patients were treated with internal fixation and conservative treatment had been used in three patients.

[Prognostic significance of hidden blood loss in total hip arthroplasty (THA)].

Objective: To explore the prognostic significance of hidden blood loss in total hip arthroplasty.

Methods: From May 2008 to July 2009, Harris hip score was used to evaluate the functions of 71 patients undergoing single side total hip arthroplasty (including 47 males and 24 females with a mean age of 68.3 years, ranged from 48 to 75 years).
