World Journal of Clinical Cases 2019年第4期7卷 431-440页

作者： xiong Xie Ming Li Tian-Tian xiong Rui Wang Liang xiao Department of Pediatrics Third Clinical Hospital China Three Gorges University Gezhouba Central Hospital

BACKGROUND Currently, it is difficult to predict the complications of children at the early stage of sepsis. Brighton pediatric early warning score(PEWS) is a disease risk assessment system that is simple and easy to operate, which has good sensitivity and specificity in disease recognition among children. Because detection indicators vary widely in children, a single indicator is difficult to assess the posttreatment status of children with *** To investigate the relationship between serological markers, Brighton PEWS, and death in children with sepsis after *** A total of 205 children diagnosed with sepsis at our hospital were enrolled. The baseline data, serum scores, and PEWS scores were recorded. In the nested casecontrol study, children who died during the study period were included in an observation group. According to the matching principle, the children who were not dead in the same cohort were included in a control group. The influencing factors of death in children with sepsis after treatment and the value of each evaluation index in predicting the prognosis of children were *** A total of 96 children were enrolled in the study, including 48 each in the observation group and the control group. Multivariate logistic regression analysis indicated that antibacterial treatments within 1 h(P = 0.017), shock(P = 0.044),multiple organ dysfunction syndrome(MODS)(P = 0.027), serum procalcitonin(PCT)(P = 0.047), serum albumin(ALB)(P = 0.024), and PEWS(P = 0.012) were independent risk factors for the death of children with sepsis. The area under the curve of the combination of ALB, PCT, and PEWS to predict the death in children with sepsis was the highest(0.908).CONCluSION Antibacterial treatments within 1 h, shock, MODS, PCT, ALB, and PEWS are independent risk factors for the death of children with sepsis. The predictive accuracy of the combination of PCT, ALB, and PEWS for the prognosis of children with sepsis is the best.

Microstructure and mechanical properties of HIP-ZTC4 during thermal exposure and tensile deformation

Rare Metals 2015年第10期34卷 692-697页

作者： Hai-Tao Jiang xiao-Qian Yan Ji-xiong Liu xiao-Ge Duan Shang-Wu Zeng National Engineering Research Center for Advanced Rolling Technology University of Science and Technology Beijing Baoti Research Institute Baoti Group Co.Ltd.

Casting titanium alloy TC4(ZTC4) after hot isostatic pressing(HIP) is one of the preferred materials in the field of aerospace manufacturing. In this paper, HIPZTC4 after a long-term thermal exposure was *** order to evaluate the variation of mechanical properties with service time, the tensile properties of this alloy after exposure at 400 °C for 100, 500, and 1,000 h were investigated. Microstructure of samples was observed by the means of optical microscopy(OM), scanning electron microscopy(SEM), and transmission electron microscopy(TEM). Tensile test was carried out under different test temperatures and fracture appearance was studied. The results show that the strength increases with exposure time due to the harder a2(Ti3Al) phase precipitated in the a phase and superficial oxygen layer formed, which results in the fact that the resistance of crack propagation could be increased and cracks first initiate between surface oxidation and the matrix. Besides, the tensile temperature also has a significant effect on the mechanical properties of HIPZTC4. The yield strength and tensile strength decrease with the increase of tensile temperature, while the total elongation increases.
