The plasma concentration of IL-6, IL-8, TNFα and LPS were assayed before and after surgical intervention, as well as when the patients vital signs became stable. The results showed: ①The patients' conditions abruptly deteriorated when the burn wound sepsis emerged.展开更多

At present, the signal feature extraction methods of these two types of events are usually designed from the view of the time domain. However, the differences of time-domain characteristics for different harmful intrusion events are not obvious, which cannot reflect the diversity of them in detail. We find that the spectrum distribution of different intrusion signals has obvious differences. For this reason, the intrusion signal is transformed into the frequency domain. In this paper, an energy ratio feature extraction method of harmful intrusion event is drawn on. Firstly, the intrusion signals are pre-processed and the power spectral density （PSD） is calculated. Then, the energy ratio of different frequency bands is calculated, and the corresponding feature vector of each type of intrusion event is further formed. The linear discriminant analysis （LDA） classifier is used to identify the harmful intrusion events in the paper. Experimental results show that the algorithm improves the recognition rate of the intrusion signal, and further verifies the feasibility and validity of the algorithm.展开更多

It had been stated in the old medical writings that the death of a burn victim was due to an assault to the heart by flame toxin. Though different kinds of salves had been used for the treatment, the efforts were usually of no avail and the victims succumbed to the injury. In the early 20th century, modern medical sciences were introduced into China and burn victims were taken care of by surgeons who had received modern medical training. However, burn care remained to be a poorly defined discipline as a minor subject in the realm of general surgery. We were totally ignorant as regards excruciating disturbances in homeostasis after a burn trauma. In the 30s of the last century, we were categorically told by our surgical professors that a burn injury covering over 30% total body surface area (TBSA) was almost invariably fatal.展开更多
