Rotavirus (RV) is one of the major pathogens responsible for acute viral gastro-enteritis in children. The infec-tion of RV is dependent upon the recognition of the host cell speciifc receptors and attachment. Thus, receptors are the important factors of infection. Recent studies have suggested that a genetic factor might play a role in the susceptibility of hosts to RV infec-tion. Histo-blood group antigens have recently been discovered as receptors binding to RV, which are important for the study of evolution. Thus it will be also crucial for the pathogenesis and epidemiology and prevention and treatment for RV. In this article, we will review the correlation of the RV infection and histo-blood group antigens and further discuss the development of optimal vaccine.

Nonalcoholic fatty liver disease(NAFLD)has become one of the most common liver diseases in the world.Considering the important role of insulin resistance in its pathogenic mechanisms,insulin sensitizers are becoming the promising pharmacological strategies for NAFLD.We collected and analyzed the relevant articles in recent years and found that pioglitazone,rosiglitazone and metformin could improve liver enzymes and insulin sensitivity of NAFLD.However,only pioglitazine was supported in ameliorating liver histology by envidences from randomized,double-blinded,controlled clinical trials.There were no much obvious adverse effects in NAFLD patients who received insulin senitizers.Small or medium samples and no more than 2 years of treatment course may be the major limitation of current studies.Future information derived from well-designed running trials will be useful in defining the clinical implications of insulin sensitizers in the treatment of NAFLD.

Objective　To study the possibility of measuring health status for residents in rural areas by the Chinese SF-36 scale. Methods　Health status for 207 residents in rural areas of Fuyang city who were 14 years old and over was measured by the Chinese SF-36 scale. The reliability and validity were analyzed. Results　The internal consistency reliability coefficients (Cronbach'α) exceeded 0.50 for all scales except SF and RE scales. Inter-scale correlation coefficients were lower than Cronbach'α coefficients for all scales except SF scale. Factor analysis identified three principal components, which could be used to explain 64.6% of the total variance. The differences of scale scores between the young group and the middle age group weren't significant. There weren't significant differences of scale scores between sexes except RP scale. The differences of scale scores between smokers and no-smokers, drinkers and no-drinkers weren't significant. Nor were the differences between various educational levels. Conclusion　Whether the Chinese SF-36 scale is suitable for measurement of health status for residents in rural areas needs further studies to give more evidences.

Objective To analyze the coverage of iodized salt and the focus population iodine nutrition after implementing new standard of iodized salt in Hainan Province.Methods Eighteen cities (counties,districts) were divided into eastern coastal,western coastal and inland areas according to coastline and terrain of Hainan Province in 2013.One township (town,street) was sampled from each city (county,district) in the east,the west,the south,the north and the center of these areas.Four villages (committees) and 15 households in each village (committee),and 40 children aged 8-10 in one primary school,20 pregnant women and lactating women were sampled from each township (town,street).Iodized salt samples collected from household were monitored by the method of direct titration;random urine samples of children aged 8-10,pregnant woman and lactating woman were tested by arsenic cerium catalytic spectrophotometry.Results Totally 6 310 edible salt samples were tested,and the median of salt iodine was 25.9 mg/kg.The coverage of iodized salt was 97.92％ (6 179/6 310).Residents consumption rate of qualified iodized salt reached 95.47％ (6 024/6 310),and the rate of non-iodized salt was 2.08％ (131/6 310).About 4 444 urine samples of children aged 8-10 were examined,and the median of urinary iodine was 165.4 μg/L,in which suitable urinary iodine (100-199 μg/L) accounted 49.3％ (2 194/4 444);about 1 286 urine samples of lactating woman were examined,the median of urinary iodine was 122.3 μg/L,≥ 100 μg/L was 60.6％ (779/1 286);about 813 urine samples of pregnant woman were examined,the median of urinary iodine was 126.6 μg/L,59.6％ (485/ 813) of this group were urinary iodine deficiency (＜ 150 μg/L).There were significant differences between the three groups in the east,the middle and the west areas of Hainan Province (children:176.7,147.7,158.0 μg/L,lactating women:148.7,108.7,106.7 μg/L,pregnant women:146.7,108.0,147.1 μg/L,H =34.70,26.76,35.95,all P ＜ 0.01).Conclusion The results have showed that pregnant woman are iodine deficiency,they should be given more iodine.

Objective 　To evaluate the clinical measurement of cerebral perfusion by dynamic CT. Methods　 Thirteen normal adults were examined by dynamic CT for the measurement of cerebral blood flow (CBF). Another dynamic CT scans with the measurement of CBF were performed separately to rule out cerebral ischemia in 5 cases and secondary Parkinson disease in 2. Results　 Normal cerebral cortical perfusion was measured at 59.3～96.8 ml*min-1*100g-1 with the　mean value 76.2 ml*min-1*100g-1. Normal white matter perfusion was measured at 27.1～43.1 ml*min-1*100g-1 with the mean value 33.9 ml*min-1*100g-1. In 5 cases of suspending cerebral ischemia, one showed increase of CBF and 4 presented decrease of CBF. In 2 cases of suspending secondary Parkinson disease, one appeared decrease of CBF and other one was normal. Conclusion　 Dynamic CT scan with the measurement of CBF can demonstrate the hemodynamic status of normal brain and pathological lesion. Combined with routine CT scan, measurement of cerebral perfusion by dynamic CT is an ideal method to show the morphological and functional changes of brain tissue simultaneously.
