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.

Objective To study the epidemic characteristics and disease spectrum of Epstein-Barr virus (EBV) infected children in Zhongshan region, Guangdong province. Methods Clinical data from the children with positive EBV-DNA detected by real-time lfuorescent quantitative PCR between 2011 and 2013 was retrospectively analyzed. Results A total of 409 cases were detected with EBV-DNA positive from 3402 cases, with a total positive rate 12%, and the positive rate is 8.1%in 2011, 10.4% in 2012, 19.5% in 2013, there were significant differences among positive rate (χ2=6804.00, P<0.05). There was no statistically signiifcant difference in the positive rate of EBV-DNA between different gender (χ2=0.239, P>0.05) and different age groups (χ2=136.96, P<0.05). The positive rate of pre-school group is the highest. EBV infection can cause multiple system diseases. The most common disease caused by EBV infection was infectious mononucleosis (61.6%), followed by respiratory tract infection (26.7%), neck lymphadenitis (3.4%), idiopathic thrombocytopenic purpura (2.4%), etc. Among the 409 cases of EBV infection, the concurrent other pathogen speciifc IgM positive cases as MP-IgM positive (n=79), CP-IgM positive (n=47), Parvovirus B19-IgM positive (n=20), HSV-IgM positive (n=11), CMV-IgM positive (n=10), and RV-IgM positive (n=4) were found. Conclusions Infectious mononucleosis is the leading disease in children infected by EBV in Zhongshan region, the annual positive rate is increasing. Multiple pathogen speciifc IgM may be detected positive in children with EBV infection, which should be interpreted in combination with clinical status.

Objective To explore the clinical characteristics, treatment and prognosis of pediatric patients with bronchiec-tasis caused by Mycoplasma pneumonia (MP) and Chlamydia pneumonia (CP). Methods The clinical data from 27 MP and CP pneumonia pediatric patients with bronchiectasis suggested by the high resolution CT were retrospectively analyzed. Results The morbility rate of bronchiectasis caused by MP and CP pneumonia is 0.56%. The mean age of these patients was 75.4 ± 52.7 months. Among them, 27 cases (100%) had cough, 19 cases (70.4%) had fever, 10 cases (37%) had respiratory distress and 20 cases had lung auscultation. Sixteen cases were MP-IgM positive, 5 cases (18.5%) were CP-IgM positive and 6 cases (22.2%) were positive of both. Eight cases were combined with other pathogens infections, in which 6 cases were bacterial infections. The imaging ifndings showed diffuse bronchiectasis in 13 cases (48.1%) and local bronchiectasis in14 cases (51.9%). The bronchoscopy found endothelium in-lfammation, mucosal swelling, partial erosion and follicular hyperplasia in 16 cases (66.7%), the formation of short column sputum bolt in 5 cases (20.8%), in which 1 case had plastic bronchitis. All patients were treated with macrolides antibiotics, 10 cases (37%) combined with methylprednisolone, 3 cases (11.1%) combined with immunoglobulin and 20 cases (74%) combined with other anti-biotics. The average length of hospitalization was 12±4.3 days. The bronchiectasis sign disappeared within 4 months in 23 cases (92%). Two cases (8%) still had bronchiectasis after 9 to 15 months, with the recurrent pneumonia. Conclusions MP and CP pneumonia can lead to acute bronchiectasis. Most of patients are recoverable with effective treatment.
