[Functional reconstruction of multiple severe deformities after extensive deep burn].

To explore new measures for functional reconstruction of multiple severe deformities as a result of extensive deep burn (total burn surface area > or = 90% TBSA, including deep burn > or = 70%TBSA) in late stage. Twelve severe burn patients with above-mentioned deformities were hospitalized in our ward during 1960--2005, the scars resulted from burns were distributed from head to foot with 173 deformities, including 27 scar ulcers. All patients lacked of self-care ability, among them some could not stand.

[Management of a patient with massive and deep burns: early care and reconstruction after convalescence].

Objective: To seek ideal strategies in saving a patient with very extensive deep burns, and measures for functional reconstruction after convalescence.

Methods: A patient with 99. 5% TBSA flame burn injury (III degrees 80%, deep second degree 14.

[Effect of bone marrow stromal cells on the apoptotic sensitivity of HL-60 and HL-60/VCR cells].

This study was aimed to investigate the effects of human bone marrow fibroblastoid stromal cell line (HFCL) on chemosensitivity of acute myeloid leukemia sensitive HL-60 cell line and multidrug-resistant (MDR) HL-60/VCR cell line in vitro co-culture. Setting up co-culture system of HL-60 or HL-60/VCR cells in direct contact with HFCL cells, or with HFCL cells separated by transwell, and exposing HL-60 or HL-60/VCR cells to different concentrations of topotecon (TPT), morphologic evidence for apoptosis was determined by staining with Wright-Giemsa stain and acridine orange/ethidium bromide (AO/EB). Cell cycle, sub-G(1) and annexin V FITC staining were detected by flow cytometry.

[Selection of approach and understanding of application in deep Over-Bite cases treated by Edgewise technique].

There are many approaches to open deep over bite with edgewise technique.As far as the three clinical pictures of deep over-bite are concerned,this article indicates that the extrusion and intrusion of teeth should be treated differently according to the technique of malocclusion-forming.It also makes a preliminary exploratory and analyse on the selection of commonly used approaches and personal understanding of clinical application.
