BACKGROUNDSeasonal influenza epidemic occurs every year in Guangzhou, which can affect all age groups. Young children are the most susceptible targets. Parents can decide whether to vaccinate their children or not based on their own consideration in China. The aim of this study was to identify factors that are important for parental decisions on vaccinating their children against seasonal influenza based on a modified health belief model (HBM).
METHODSA cross-sectional study was conducted in Guangzhou, China. A total of 335 parents who had at least on child aged between 6 months and 3 years were recruited from women and children's hospital in Guangzhou, China. Each eligible subject was invited for a face-to-face interview based on a standardized questionnaire.
RESULTSUptake of seasonal influenza within the preceding 12 months among the target children who aged between 6 months and 36 months was 47.7%. Around 62.4% parents indicated as being "likely/very likely" to take their children for seasonal influenza vaccination in the next 12 months. The hierarchical logistic regression model showed that children's age (odds ratio [OR] =2.59, 95% confidence interval [CI]: 1.44-4.68), social norm (OR = 2.08, 95% CI: 1.06-4.06) and perceived control (OR = 2.96, 95% CI: 1.60-5.50) were significantly and positively associated with children's vaccination uptake within the preceding 12 months; children with a history of taking seasonal influenza vaccine (OR = 2.50, 95% CI: 1.31-4.76), perceived children's health status (OR = 3.36, 95% CI: 1.68-6.74), worry/anxious about their children influenza infection (OR = 2.31, 95% CI: 1.19-4.48) and perceived control (OR = 3.21, 95% CI: 1.65-6.22) were positively association with parental intention to vaccinate their children in the future 12 months. However, anticipated more regret about taking children for the vaccination was associated with less likely to vaccinate children within the preceding 12 months (OR = 0.21, 95% CI: 0.08-0.52).
CONCLUSIONSThe modified HBM provided a good theoretical basic for understanding factors associated with parents' decisions on their children's vaccination against seasonal influenza.

A simple and cost-effective indirect competitive enzyme-linked immune sorbent assay (ic-ELISA) was developed to rapidly screen the content of aflatoxin B1 (AFB1) in lotus seeds, and the results were confirmed by ultra-fast liquid chromatography-tandem mass spectrometry( UFLC-MS/MS). Matrix-matched calibration expressed a good linearity ranging from 0. 171 to 7. 25 µg · L(-1) for AFB, with R2 > 0.978. The medium inhibitory concentration( IC50 ) for AFB1 was 1.29 µg · L(-1), the recovery for AFB1 was 74.73% to 126.9% with RSD < 5%, and the limit of detection (IC10) was 0.128 µg · L(-1). The developed ic-ELSIA method was applied to rapid analysis of AFB, in 20 lotus seeds samples and the results indicated that the contents of AFB, in samples 1-15 were in the range of 1. 19- 115. 3 µg · kg(-1) and in 40% of the samples exceeded the legal limit(5 µg · kg(-1)), while the contamination rate of AFB, in samples 16-20 was 40%. Pearson correlation coefficient(r) reached 0.997 for AFB1 content in the samples detected by ic-ELSIA and UFLC-MS/MS methods. The results proved that the developed ic-ELISA method is simple, sensitive and reliable, and can be used for rapid and high-throughput screening of AFB1 in lotus seeds

Objective To compare and evaluate the efficacy of three operating procedures to produce permanent rat models of cerebral ischemia, including mortality, neurological evaluation score, infarction volume of ischemia and time consumed in the operation. Methods The rats were randomly divided into three groups. Group 1: The common carotid artery (CCA) and external carotid artery (ECA) were ligated during the operation and ICA was clipped temporarily by artery clamp. Group 2: The CCA and ECA were ligated and the superior thyroid artery and pterygopalatine artery were exposed but not ligated. Silk suture was utilized to hang the internal carotid artery (ICA). Plastic suture was inserted into ICA and stepped over the initiation point of pterygopalatine artery under microscopic observation. Group 3: The CCA and ECA were ligated and ICA was hanged with a silk suture, and the pterygopalatine artery was not exposed, but during the period of inserting plastic suture, the proximal part of the suture was pressed to make the suture's round distal end elevated, and then pass the initial point of pterygopalatine artery. Mortality, neurological score, volume of ischemic infarction and operation time consumed of the three groups were compared after the operation. Results The procedure to prepare the model was most efficient in the group 3, taking only 17.5 min to complete, significantly less than that in the group 1 (50 min) and group 2 (40 min), (P<0.05), and with a lower mortality and more steady neurological evaluation score and infarction volume. Conclusion The use of the third operating method can shorten the operation time and improve the efficacy of operation. Using this method, more consistent and repetitive focal cerebral ischemia models can be produced effectively, and meet the demands of clinical trials.
