Sepsis commonly occurs in severe post-burn patients, often resulting in death. We aimed to evaluate the influence of early enteral feeding on outcomes in patients with extensive burns, including infection incidence, healing and mortality. We retrospectively reviewed 60 patients with extensive burns, 35 who had received early enteral nutrition and 25 who had received parenteral nutrition. Average healing time, infection incidence and mortality were clinically observed. Hemoglobin and serum albumin were monitored weekly in both groups during treatment. Causative organisms were identified in patients with sepsis. Infection incidence was significantly less in the enteral nutrition group than the parenteral nutrition group (17.1% vs 44.0%; p = 0.023); and latency duration was longer in the enteral nutrition group than in the parenteral nutrition group (30.5 ± 4.7 days vs 14.5 ± 2.3 days; p<0.001). Duration of antibiotic therapy of the enteral nutrition group was significantly shorter than that of the parenteral nutrition group (12.5 ± 3.0 days vs 19.8 ± 3.6 days; p<0.001). Mean hemoglobin results (10.1 ± 1.3 g/L vs 8.3 ± 1.5 g/L; p<0.001) and serum albumin results (44.7 ± 5.7 g/L vs 36.2 ± 6.9 g/L; p<0.001) of enteral nutrition and parenteral nutrition groups, respectively, provided an overview of systemic nutrition and protein metabolism, suggesting higher systemic nutrition and protein synthesis in enteral nutrition group than in parenteral nutrition group. Risk of post-burn infection is reduced in burn patients who are supported by earliest possible enteral nutrition.

Image correction technology is very important both for image mosaic and for measurement. To overcome the defects and limitations of polynomial and TPS models, basing on polynomial and TPS correction models, an improved algorithm is proposed in this paper. In this method, the processing is divided into two stages, global correction and local correction, and different screening methods of GCPs are adopted in different stages. By fully utilizing all GCPs, the respective correction advantages of the two sub-models can be efficiently demonstrated, and, in the meanwhile, the ultra-plus effect of this combination can be stimulated. Eventually, image correction accurcy can be improved. Simulation results show that, comparing with currently available approximate geometric correction methods, this method has high accuracy, good robustness and can effectively coordinate the conflict of the global correction and local correction.

Visible images are always slantwise, simultaneity ground control points layout are not easy, so we must choose one method which can correct the slantwise image based on few reference points. When exterior orientation elements known, the paper can build a correction plane founded on collinearity equations, and then correct the slantwise image using gray interpolation. The corrective effect is very visible, and the speed is rapid.
