Objective To study the status of filial piety and anxiety among adults, explore the relationship between filial piety and anxiety, and analyze the factors that affect anxiety. Methods A total of 915 adults from Jiangsu and Anhui provinces were selected using the General Information Questionnaire, the Chinese Filial Values Index scale (FVI) and Zung Self-rating Anxiety Scale (SAS), through the online platform and on-site payment, recovery of the questionnaire to investigate. Results The overall level of filial piety was 85.23 ± 9.22 , among which the care dimension was 84.60 ± 9.75 and the respect dimension was 86.12 ± 11.76;111 adults were with anxiety (12.13％), and patients with mild and moderate anxiety respectively were 88 (9.62％) and 23 (2.51％) cases. The overall level of filial piety was negatively correlated with the level of anxiety (r=-0.403, P<0.01), and the level of filial piety is an independent factor affecting the level of anxiety in adults(B=-0.299,P<0.01). Other factors also include the quality of sleep, illness, duration, beliefs, occupational stability. Conclusion The high level of filial piety in adults is moderately correlated with anxiety and is an independent risk factor for anxiety in this population. The adult's education of filial piety should be strengthened and the positive adjustment of filial piety to anxiety should be strengthened in order to better solve the physical and mental health problems caused by the pension burden.

Henoch-Sch?nlein purpura is also known as IgA vasculitis. The kidney involvement, namely Henoch-Sch?nlein purpura nephritis (HSPN), is one of IgA vasculitis's main clinical manifestations. Galactose-deficient IgA1 plays an important role in the pathogenesis of HSPN, which not only is similar to the "four-hits hypothesis" of IgA nephropathy, leading to IgA1 deposit in the mesangial region of the kidney, but also is closely related to inflammation with more complicated compositions of its immune complex. Therefore, abnormal glycosylation of IgA1 is expected to be a biomarker for diagnosis and prediction of HSPN pathogenesis, disease activity determination and prognosis prediction. Here, the paper reviews the research progress on the pathogenesis and clinical application of abnormal glycosylation of IgA1 in HSPN.
