[Objectives]The aim of this study was to investigate the effects of APS-sEPS(a polysaccharide compound of Astragalus polysaccharides and sulfated Epimedium polysaccharide)on intestinal mucosal immunity and structural morphology.[Methods]Firstly,the diarrhea model was established using the optimal dose of magnesium sulfate in mice.Then,the diarrhea mice were randomly divided into three groups and given either physiological saline(diarrhea model group)or injected with APS-sEPS or APS.The normal mice were selected as a control group.After administration,the duodenum,jejunum and ileum were processed microtome section,and observed for describing the small intestine morphology,villus height and crypt depth.The tissue homogenates of the duodenum,jejunum and ileum were gathered to detect the changes of sIgA,IL-4 and IL-10.[Results]The results indicated that APS-sEPS could effectively relieve diarrhea in mice.In the APS-sEPS group,the villus heights of duodenum,jejunum and ileum were increased and the depth of crypt was reduced.The contents of IL-4,IL-10 and sIgA in jejunum and ileum in APS-sEPS group were significantly higher than that in the control group(P<0.05).[Conclusions]These results indicated that APS-sEPS promoted the recovery of intestinal morphological structure and enhanced the mucosa immunity of the small intestine. 展开更多

[Objective] The aim was to explore the mechanism of Chinese medicinal herb to enhance the body's immune. [Method] The quantitative distribution of immunocytes in chicken small intestinal mucosa lymphoid tissue-secretory type immune globulin cell A were dynamic observed to research chicken immune organ growth with histology conventional slice technology and immunohistochemistry dye. 1 day age healthy roosters were divided into 3 groups: the group 3 was control group. 1% and 0.5% concentration of Chinese herbal medicine immunopotentiator drinking water were added in the group 1 and 2 in continuous 60 d. The immune organ index was determined every 12 d and the histotomy of chicken small intes- tine in group control and 1% were taken for histological observation on day 24, 36 and 48. [ Result] Treatment group immune organ index was significantly higher than that of the control group and 1% group of small intestinal villus inherent intraformational immune cells number significantly increased (P〈0.01) compared with controls. Day 36 age group and day 48 group immune cells were higher than day 24 group of cell number (P〈 0.01 ). [ Conclusionl Chinese medicinal herb had obvious role in promoting chicken immune organ growth and obvious influence on the quantity change of the intestinal mucosal immune cells. 展开更多

BACKGROUND Coronavirus disease 2019(COVID-19)is a public health emergency of international concern.The global population lacks immunity to COVID-19 and is generally susceptible.Underlying conditions,especially chronic respiratory diseases,may affect progression,treatment and prognosis of COVID-19.CASE SUMMARY We report a patient with confirmed COVID-19 combined with asthma.It took 41 d from disease onset to discharge to obtain two negative tests for this coronavirus.CONCLUSION This case indicates the dynamic clinical characteristics,laboratory and computed tomography findings and adjustment of treatment,and the possible relationship between glucocorticoid therapy and coronavirus clearance. 展开更多
