Objective To analyze the change of disease spectrum and the direct cause of death in Xi'an Children's Hospital emergency patients in the past 2 years.Methods The cases of death in 130 emergency cases from 2009 to 2010 were retrospectively analyzed.Results The main causes of death in 2009 were pneumonia,congenital heart disease,asphyxia,neonatal pulmonary hemorrhage and intracranial hemorrhage.Meanwhile,The main cause of death in 2010 were pneumonia,asphyxia,viral encephalitis,congenital heart disease and neonatal pulmonary hemorrhage,which significantly changed compared with 2009.Major direct causes of death were found:respiratory failure in 25 cases (27.5%),heart failure in 17 patients ( 18.7% ),shock in 17patients ( 18.7% ),asphyxia in 16 cases ( 17.5% ),and hernia in 16 cases ( 17.5% ),Conclusion In order to reduce the mortality rate of emergency patients,we should strengthen health care,actively manage pulmonary infection,systemic infection,and shock,control heart failure,and prevent aspiration.

This paper developed a calculation method to acquire the yield load P of bone plate during four-point bending test. This method is based on the displacement--force (δ-F) curve function f(M)(δ) obtained from the test, each slope of the curve was calculated using piecewise smooth function and the line segment in f(M)(δ) elastic deformation area was searched by setting the minimum slope T. Slope S was obtained through linear fit so as to build parallel displacement function f(L)(δ). Then, approximating intersection point of f(M)(δ) and f(L)(δ) was obtained through linear interpolation. Thus, yield load P was acquired. The method in the paper was loyal to YY/T 0342-2002 regulation and was liable to program calculation. The calculating process was nothing to do with whether the initial point during the test was preloaded or unloaded, and there was no need to correct the original point. In addition, T was set in an ideal fitting level guaranteed by the fitting coefficient of determination R2, and thus S was very close to the real value, and P was with a high accuracy.

This study is to compare the influence of CYP2D6 *3 and *4 genotypes and phenotypes on the metabolic activity of CYP2D6 in Chinese Han, Uygur and Kazakh ethnic groups. Allele specific amplification (ASA) was used to determine the CYP2D6*3 and CYP2D6*4 genotypes. Phenotypes of CYP2D6 in all subjects were determined using dextromethorphan as probe drug by HPLC methods. Among the 132 Han subjects, one subject (0.76%) exhibited the *1/*3 combination, and one (0.76%) exhibited the *1/*4. Among the 136 Uygur subjects, 4 subjects (2.94%) showed the *1/*3 combination, 12 (8.82%) showed *1/*4, 4 (2.94%) showed *4/*4, and one (0.74%) showed *3/*4. Among the 116 Kazakh subjects, 2 (1.72%) exhibited the *1/*3 combination, 7 (6.03%) exhibited *1/1*4, and one (0.86%) showed *4/*4. This research revealed significant differences in the occurrence frequencies of the CYP2D6 genotype between Han and Uygur ethnic groups, as well as between Uygur and Kazakh populations. However, no difference was found between Han and Kazakh populations. In addition, the prevalence of PMs of the Uygur is comparable to that of the Caucasians. However, the molecular mechanism underlying the poor metabolism is different in these two populations.
