This paper reviews the absorption, distribution and metabolic characteristics of dietary soluble silicic acid in human body, as well as its relationship with human health.Available data show that it has lots of supporting evidences that dietary soluble silicic acid can prevent osteoporosis, maintain vascular health, improve the symptoms of Alzheimer's disease and multiple sclerosis.Its unique crosslinking ability and antagonism to toxic aluminum play a crucial role. In the early stage of human life, there is a strong demand for silicon, and the level of silicon in the aged is generally reduced, suggesting that pregnant women and old people should pay attention to the intake of soluble silicic acid. It is suggested to strengthen the basic and applied research on dietary soluble silicic acid,and gradually establish the relevant nutrition and hygiene standards.Objective To understand the genotype distribution and molecular epidemiological characteristics of hepatitis E virus (HEV) isolated in Shandong Province, 2017. Methods The cases of hepatitis E who were reported to the National Notifiable Disease Reporting System (NNDRS) from January to December 2017 in Shandong Province were chosen as the subjects in the study. Epidemiological information and blood samples were collected from 1 045 participants. Both anti-HEV IgM and anti-HEV IgG were detected using ELISA method. Viral nucleic acids were extracted only from those of anti-HEV IgM positive samples. Nested reverse transcription-polymerase chain reaction was carried out to amplify 644 bp nucleotide sequences within HEV open reading frame (ORF) 2 region. The sample sequences together with reference sequences from GenBank were subjected to phylogenetic analysis. Results In total, 638
