An outbreak of hand, foot, and mouth disease was reported through hospital-based surveillance in Nanchang, China in 2014. A total of 244 cases were reported, 176 (72.1%) cases were tested positive for enteroviruses by direct reverse transcription-polymerase chain reaction, in which enterovirus A71 (EV-A71), coxsackievirus A16 (CV-A16), and untyped enteroviruses (UEV) accounted for 84.1%, 3.4%, and 12.5%, respectively. In this outbreak, children under 5 years old constituted more than 98% of the positive cases, and the ratio of male to female cases was 2.6 to 1 (P<0.01). Phylogenetic analysis indicated that the Nanchang EV-A71 strains belonged to subgenotype C4a undergoing continuously evolutionary changes. © 2015 Wiley Periodicals, Inc. Source

Dietary or nutrient patterns represent the combined effects of foods or nutrients, and elucidate efficaciously the impact of diet on diseases. Because the pharmacotherapy on attention deficit hyperactivity disorder (ADHD) was reported be associated with certain side effects, and the etiology of ADHD is multifactorial, this study investigated the association of dietary and nutrient patterns with the risk of ADHD. We conducted a case-control study with 592 Chinese children including ADHD (n = 296) and non-ADHD (n = 296) aged 6–14 years old, matched by age and sex. Dietary and nutrient patterns were identified using factor analysis and a food frequency questionnaire. Blood essential elements levels were measured using atomic absorption spectrometry. A fish-white meat dietary pattern rich in shellfish, deep water fish, white meat, freshwater fish, organ meat and fungi and algae was inversely associated with ADHD (p = 0.006). Further analysis found that a mineral-protein nutrient pattern rich in zinc, protein, phosphorus, selenium, calcium and riboflavin was inversely associated with ADHD (p = 0.014). Additionally, the blood zinc was also negatively related to ADHD (p = 0.003). In conclusion, the fish-white meat dietary pattern and mineral-protein nutrient pattern may have beneficial effects on ADHD in Chinese children, and blood zinc may be helpful in distinguishing ADHD in Chinese children. © 2016 by the authors; licensee MDPI, Basel, Switzerland.

Background:The mechanisms underpinning Kawasaki disease (KD) are incompletely understood. There is an unmet need for specific biomarkers for the early diagnosis of KD.Methods:Eighty-five KD patients suffering from acute-phase and subacute-phase KD, 40 healthy children, and 40 febrile children comprised the study cohort. An enzyme-linked immunosorbent assay was used to measure plasma levels of C1q, C1q-circulating immune complex (C1q-CIC), mannan-binding lectin-associated serine protease (MASP)-1, factor B, C4d, C3d, C5a, C5b-9 and CD59.Results:Plasma concentrations of factor B and C5a in the acute phase were lower than those in healthy and febrile control groups (all P < 0.05). Compared with acute-phase KD patients, plasma concentrations of C1q, factor B, and C3d in KD patients were increased significantly (P < 0.05), but those of C4d, MASP-1 and CD59 decreased significantly (P < 0.05), in patients with sub-acute KD.Conclusion:These data suggest that more than one pathway in the complement system is activated in KD. Importantly, decreased plasma concentrations of factor B and C5a in the acute phase (6-10 d) could be employed as biomarkers for the early diagnosis of KD.

Aims: To examine single nucleotide polymorphisms in the protein tyrosine phosphatase N22 gene (PTPN22) and to study their association with Type 1 diabetes in a Chinese cohort. Methods: Three hundred and sixty-four young patients with Type 1 diabetes and 719 healthy children were included in this case-controlled study. The genotypes of rs1217385, rs2488457 (-1123C>G), rs1217414, rs1217419, rs3765598 and rs2476601 (1858C>T) in the PTPN22 gene were determined using the SNaPshot method. Alleles, genotypes and haplotype frequencies were compared between patients with Type 1 diabetes and healthy control subjects. The association between single nucleotide polymorphisms and clinical traits/autoantibody status was also analysed. Results: The single nucleotide polymorphism, rs1217419, located in the second intron of the PTPN22 gene was associated with Type 1 diabetes (odds ratio 1.5, 95% CI 1.14-1.97, P = 0.003). An additional single nucleotide polymorphism, rs1217385, was also associated with Type 1 diabetes; however, the association was secondary to that of rs1217419. The previously reported single nucleotide polymorphism that is associated with Type 1 diabetes (-1123G>C) had only marginal association with Type 1 diabetes in our study. A marginal association was also identified between -1123G>C and glutamic acid decarboxylase autoantibody positivity in patients with Type 1 diabetes. There was no association between the single nucleotide polymorphism 1858C>T and Type 1 diabetes in our studied cohort. Conclusions: Our study confirmed that PTPN22 is a gene that contributes to Type 1 diabetes susceptibility. The primary association occurs with single nucleotide polymorphism rs1217419 and there is clear heterogeneity of the association between PTPTN22 polymorphisms and Type 1 diabetes in a Chinese population compared with other populations. © 2013 Diabetes UK.

Background: Childhood diabetes has become a growing concern. We conducted a study to evaluate the status and trend of diabetes from 14 medical centers in China. Pre-diabetic status among obese children was also noted. Methods: Hospital medical records were reviewed, and data of diabetes were collected from 1995 through 2010. We took every five years as a calculation unit to analyze the trend of new-onset diabetes. Data on obesity were collected in the recent five years. Results: A total of 4 337 836 patients aged 0-18 years were discharged from the 14 centers. The prevalence (per 100 000 persons) of new-onset type 1 diabetes, type 2 diabetes and other types of diabetes were 96.8, 8.0, and 3.3, respectively. The prevalence of type 1 diabetes increased from 90.9 to 92.9 and 101.4, while type 2 diabetes increased from 4.1 to 7.1 and 10.0 in every five years (P<0.0001). The increasing trend was significant from Southwest to East and North China (type 1 diabetes from 59.76 to 80.02 and 120.45, type 2 diabetes from 2.52 to 3.77 and 15.64 (per 100 000 persons) (all P<0.0001). Well developed areas in China had a higher prevalence compared to less developed areas [type 1 diabetes: 151.51 vs. 32.2 (per 100 000 persons); type 2 diabetes: 15.16 vs. 1.64 and others: 7.54 vs. 0.42 (per 100 000 persons)]. Of the 3153 obese children, 18.24% had impaired fasting glucose (IFG), 5.99% had impaired gulose tolerance (IGT), and 4% had combined IFG and IGT. Conclusions: The prevalence of childhood diabetes in China has increased dramatically, with type 2 diabetes exceeding type 1 diabetes. The incidence rate of abnormal glucose metabolism in obese children has reached 28.26%. © 2013 Children's Hospital, Zhejiang University School of Medicine and Springer-Verlag Berlin Heidelberg.
