A Geographical and Temporal Risk Evaluation Method for Red-Light Violations by Pedestrians at Signalized Intersections: Analysis and Results of Suzhou, China.

Red-light violations of pedestrians crossing at signal intersections is one of the key factors in pedestrian traffic accidents. Even though there are various studies on pedestrian behavior and pedestrian traffic conflicts, few focus on the risk of different crosswalks for the violating pedestrian group. Due to the spatio-temporal nature of violation risk, this study proposes a geographical and temporal risk evaluation method for pedestrian red-light violations, which combines actual survey and video acquisition.

Recombinant human granulocyte macrophage colony stimulating factor in deep second-degree burn wound healing.

Background: The aim of this study was to explore the effects of recombinant human granulocyte macrophage colony stimulating factor (rhGM-CSF) on deep second-degree burn wound healing.

Methods: In this study, 95 patients with a total of 190 burn wounds were treated with either rhGM-CSF or placebo, separated into 2 groups by treatment type. Wound healing rate, wound healing time, histopathological condition, and scar scale were all compared between the 2 groups.

[Analysis of clinical data of 16 595 pediatric burn patients during fifteen years].

Objective: To analyze the epidemiological characteristics of pediatric burn in the midwest region of Inner Mongolia and the related areas, and to provide reference for seeking pertinent measures of prevention and treatment.

Methods: Medical records of patients hospitalized in the 253rd Hospital of PLA, the 322nd Hospital of PLA, and the Inner Mongolia Autonomous Region Hospital from January 1996 to December 2010 were collected. Patients were divided into pediatric burn group with specific reason (group SF, with scald resulted from construction defect of Guo-lian-kang--a heatable brick bed linked to a cooking pot), and burn control group with other causes (group C) according to the main injury cause.

[The reverse flow island flap nourished by sural nerve nutrition blood vessel for repair of severe frostbite of feet].

Objective: The study was to verify the feasibility of an improved method using reverse flow island flap nourished by the sural nerve nutrition vessel to repair severe frostbite of feet.

Methods: At the proximal end of the principal flap, an auxiliary triangular skin flap of 6.5 - 7 cm in length was designed in order to cover the pedicle of the principal flap.
