RESUMEN
Objective To investigate the epidemiological characteristics and drug sensitivity of non-typhoid salmonella in Zhongshan city.Methods We collected the positive cases of non-typhoid salmonella in children of Zhongshan city from 2013 to 2015.The sex,age,place of residence,onset time and main serum type of these cases were collected.The characteristics of the cases were described by descriptive epidemiologi-cal study.Results From 2013 to 2015,3 040 stool specimens from patients with enteritis were collected and 402 strain of non-typhoid salmonella were separated out. The total detection rate was 13.22%,the annual detection rate were 10.26%,12.21% and 16.76%,respectively.The peak period was from July to August every year.Of the 402 children,240 were male,162 were female,and the ratio was 1.48:1.The minimum age was 1 month,the maximum was 5 years and 8 months,the mean age was 13.62 months.All patients were characterized by diarrhea and fever,including 64 cases of bloody stool and 1 case of sepsis.The most com-mon serotypes were 4,5,12:i:-and 4,12:i:-.The resistant strains were salmonella typhimurium and variety salmonella typhimurium strains.From 2013 to 2015,the resistance rate of ceftriaxone and ceftazidime in non-typhoid salmonella isolates increased linearly (ceftriaxone: 17.35%, 26.23%, 39.01%; ceftazidime:12.24%,17.21%,30.77%).The differences were statistically significant(χ2=30.3,P<0.01;χ2=26.3, P<0.01).Conclusion The positive rate of nontyphoid salmonella increased year by year from 2013 to 2015.The most common serotype was salmonella typhimurium, and the resistant strains were salmonella typhimurium and salmonella typhimurium variety.The resistance rate of non-typhoid salmonella to ceftriaxone and ceftazidime increased year by year,and the highest rate of ceftazidime resistance was in July 2015.Non-typhoid salmonella was more resistant to ceftriaxone than ceftazidime.
RESUMEN
Disease is closely related to nutrition,and disease state of hospitalized children with nutrient consumption and malnutrition is worrying. Malnutrition affects not only children′s growth,reduce the body func-tion,but also can increase the nutrition related complications and mortality. However currently the decision crite-ria of nutrition risk screening and evaluation method are not identical, there is no systemic, standard, unified plan,which cause a lot of malnutrition cases misdiagnosis and miss the timing of the early intervention. There-fore,it is necessary to do nutritional risk screening,nutrition assessment and nutritional surveillance for hospital-ized children,so that we can timely find the nutritional problems and take reasonable nutrition support and inter-vention measures. In this paper,the hospitalized children with nutritional risk screening and nutrition evaluation research progress are reviewed briefiy.
RESUMEN
Objective To discuss the newrborn ARDS first time blood gas analysis characteristic.and the clinical significance. Methods Application blood gas analysis and PaO2/PAO2,QS/QT,PaO2/FiO2,A-ac-DO2,RI and so on many indexes of blood gas analysis,to 2001~2005 year period were hospitalized in my courtyard NICU makes clear diagnoses the ARDS parallel breath machine treatment 20 examples trouble carries on monitors. Results First time when blood gas analysis 60% trouble prompt low oxygen blood sickness (PaO2<50 mm Hg).Parameter the and so on RI,QS/QT,A-acDO2,PaCO2/FiCO2,PaCO2/PaO2 values separately were:3.32±4.18,10±9.85,149.06±159.54,94.96±50.47,0.12±0.05. 72 hours ventilation after the breath machine. Conclusion Carries on the clinical appraisal using these targets to ARDS, to early strives for the breath machine treatment,the judgement condition and estimates pre-after has the vital significance.
