ABSTRACT
Objective To explore the etiology and epidemiological characteristics of fever and rash syndrome a mong children under the age of five years in Northwest China from 2009 to 2015.Methods Descriptive epidemiological analysis was conducted based on the monitoring data in sentinel hospitals,which was from the information management system of national infectious disease monitoring from 2009 to 2015 in Gansu,Qinghai,Inner Mongolia and Xinjiang.Results The results showed that the major pathogens of fever and rash syndrome among children under the age of five years were enterovirus,measles virus,varicella-zoster virus (VZV) and rubella virus.The major pathogens among children in the age group of 0-years and in the age group of 1-5 years were measles virus and enteroviruses,respectively.Among the positive cases of enterovirus,the positive detectable rates of human enterovirus 71 (EV71) and coxsackie A16 (CA16) were 47.18％ and 45.59％,respectively.The incidences of enterovirus and measles virus infection were mainly concentrated on May to July and March to May,respectively.Conclusions The major pathogens of fever and rash syndrome among children under the age of five years in Northwest china were enterovirus and measles virus with seasonal epidemic characteristics.Therefore,the prevention and control of measles and hand-foot-mouth disease should be strengthened.
ABSTRACT
0bjective To investigate the serum total bilirubin level of healthy population in northwest area of China.Methods According to the guiding principle and the screening standard of C28-P3,722 individuals conforming to the screening standard from October 2011 to January 2012 were collected.Serum total bilirubin was determined with diazo reagent method(Roche)on the P module of Hitachi 7600 automatic biochemistry analyzer,and the vanadate reagent method(WAKO)on the D module of the Hitachi 7600 automatic biochemistry analyzer,respectively.The detection results were analyzed between different analysis systems,between country and city and among different age groups by SPSS13.0.The top and bottom limitations of 95% reference interval recommen-ded by the C28-P3 file were calculated by the non-parametric method.Results Serum total bilirubin detection results had no statis-tically significant differences between the two kinds of detection methods,between rural and urban populations,among all ages and genders (P >0.05).The ultimate reference interval of serum total bilirubin in the northwest area was 2.19 -29.29 μmol/L.Con-clusion The differences of serum total bilirubin reference interval exist between the healthy population in the Northwest area of China and the current reference interval used in domestic and foreign population.Establishing the reference intervals of new bio-chemical test item suitable for China′s population will provide the scientific basis for the evaluation of disease diagnosis,treatment, prognosis judgment and health assessment in the Chinese population.
