Safety, tolerability, pharmacokinetic, pharmacodynamic and immunogenicity profiles of Exendin-4-IgG4-Fc in healthy subjects: A phase 1, single-centre, randomized, double-blind, dose escalation study.

Aim: Novel long-acting drugs for type 2 diabetes mellitus may optimize patient compliance and glycaemic control. Exendin-4-IgG4-Fc (E4F4) is a long-acting glucagon-like peptide-1 receptor agonist. This first-in-human study investigated the safety, tolerability, pharmacokinetic, pharmacodynamic and immunogenicity profiles of a single subcutaneous injection of E4F4 in healthy subjects.

[Quantitative analysis of the exposure of suboccipital far-lateral approach and postauricular transtemporal approach to the jugular foramen region].

Objective: To study the exposure of suboccipital far-lateral approach and postauricular transtemporal approach to the jugular foramen region based on quantitative measurements, and provide reliable anatomic data for selecting surgical approach individually and protecting the function of important structures.

Methods: The complete approach of the suboccipital far-lateral approach and the postauricular transtemporal approach were reproduced in twelve (twenty-four sides) head-neck specimens of adults be fixed in 10% formalin. The exposure area to the jugular foramen region was obtained using a stereotactic device, and the length of exposure of the clivus and the trigeminal nerve were measured using a vernier caliper.

[Total mesorectal excision versus conventional radical surgery for rectal cancer: a meta analysis].

Objective: To compare treatment outcomes of total mesorectal excision (TME) with those of conventional radical surgery (CRS) for rectal cancer.

Methods: Literature reviews were performed with key words, such as rectal cancer, total mesorectal excision, TME on all studies reported on TME versus CRS for rectal cancer between January 1986 to May 2006. According to the same screening criteria, 17 clinical studies were included in our systematic reviews.
