Objective:To study the effect and underlying mechanism of BCG polysaccharide and nucleic acid ( BCG-PSN) in hy-persusceptibility in guinea pigs to explore the improvement method for the quality control model of BCG-PSN. Methods:The ovalbumin induced hypersusceptibility animal model was established, the effect of BCG-PSN on hypersusceptibility in guinea pigs was observed. According to the guideline for immunity toxicity study on Chinese traditional medicine and natural medicine, the hypersusceptibility tests were carried out. Serum IgE and histamine were determined by ELISA. Results:The guinea pigs in the model group and the low dosage BCG-PSN group showed strong anaphylactic symptoms, while the middle and high dosage BCG-PNS groups showed fewer symp-toms. The level of IgE in the model group was (1. 673 0 ± 0. 158 6) μg·ml-1 and (1. 683 1 ± 0. 228 1)μg·ml-1 before and after the attacking, respectively, which was higher than that in the control group(P<0. 01). The levels of IgE in the middle and high dos-age BCG-PNS groups were decreased compared with those in the model group before and after the attacking(P<0. 01). The same re-sults were observed in the levels of histamine. Before and after the attacking, the levels of histamine in the model group was (1. 499 7 ± 0. 133 1) ng·ml-1 and (1. 512 1 ± 0. 050 6) ng·ml-1 , respectively, while the levels of histamine in low, middle and high dos-age BCG-PNS groups were decreased compared with those in the model group before and after the attacking(P<0. 01). Conclusion:BCG-PSN can dose-dependently inhibit the anaphylactic reaction induced by ovalbumin.

Objective:To observe the aging-related trends and age-sensitive changes in postural control reaction time(RT)and movement time(MT)during the adaptive balance after instability. Method:A total of 97 healthy adult subjects aged 20-79 were tested for posture control time using the DE-A somatosensory balance detection system.The test included postural adjustment RT and MT during the adaptive balance(e.g.forward,backward,left and right)tilts of the support surface under static and dynamic balance states.The subjects were sequentially divided into six age groups based on 10-year age intervals,with 16 in Group 1(20-29 years),10 in Group 2(30-39 years),17 in Group 3(40-49 years),18 in Group 4(50-59 years),31 in Group 5(60-69 years)and 5 in Group 6(70-79 years).The age-related trends and age-sensitive changes in postural control RT and MT were observed and analyzed. Result:The postural control RT and MT increased with age.In static balance,all RT and MT indicators were longer in group 6 than in groups 1 to 5,with significant differences compared with groups 1 to 4(P<0.05)but no significant differences compared to group 5(P>0.05).All RT and MT indicators were longer in group 5 than in groups 1 to 4,and there were significant differences(P<0.05).All RT and MT indicators were lon-ger in group 4 than in groups 1 to 3,with a significant difference compared with group 1 in RT when the support surface was tilted to the right(P<0.05),but no significant differences between groups for the remain-ing indicators(P>0.05).All RT and MT indicators were longer in group 3 than in groups 1 to 2,with a sig-nificant difference compared with group 1 in MT when the support surface was tilted to the left(P<0.05),but no significant differences between groups for the remaining indicators(P>0.05).There was no significant difference(P>0.05)between group 2 in all RT and in MT compared with group 1.In dynamic balance,all RT and MT indicators were longer in group 6 than in groups 1 to 5,with significant differences compared with groups 1 to 4(P<0.05)but no significant differences compared with group 5(P>0.05).All RT and MT indicators were longer in group 5 than in groups 1 to 4,but there were no significant differences(P>0.05).All RT indicators were longer in group 4 than in groups 1 to 3,with no significant differences compared with group 1 in RT when the support surface was tilted to the left(P>0.05),while there were significant dif-ferences between groups for the remaining RT indicators(P<0.05).All MT indicators were longer in group 4 than in groups 1 to 3,with significant differences compared with group 2 in MT when the support surface was tilted to the back and left(P<0.05),while there were no significant differences between groups for the remaining RT indicators(P>0.05).All RT indicators were longer in group 3 than in groups 1 to 2,with no significant differences compared with group 1(P>0.05).All MT indicators were longer in group 3 than in groups 1 to 2,with significant differences compared with group 1(P<0.05).There was no significant differ-ence between group 2 in all RT and in MT compared with group 1(P>0.05). Conclusion:The postural control RT and MT during the adaptive balance after instability gradually increase with aging.The deterioration of postural control response time and motion time in static balance may start to become evident around the age of 60,while in dynamic balance,these deteriorations may begin to appear around the ages of 50 and 40,respectively.

Intestinal fibrosis associated stricture is a common complication of inflammatory bowel disease usually requiring endoscopic or surgical intervention. Effective anti-fibrotic agents aiming to control or reverse intestinal fibrosis are still unavailable. Thus, clarifying the mechanism underpinning intestinal fibrosis is imperative. Fibrosis is characterized by an excessive accumulation of extracellular matrix (ECM) proteins at the injured sites. Multiple cellular types are implicated in fibrosis development. Among these cells, mesenchymal cells are major compartments that are activated and then enhance the production of ECM. Additionally, immune cells contribute to the persistent activation of mesenchymal cells and perpetuation of inflammation. Molecules are messengers of crosstalk between these cellular compartments. Although inflammation is necessary for fibrosis development, purely controlling intestinal inflammation cannot halt the development of fibrosis, suggesting that chronic inflammation is not the unique contributor to fibrogenesis. Several inflammation-independent mechanisms including gut microbiota, creeping fat, ECM interaction, and metabolic reprogramming are involved in the pathogenesis of fibrosis. In the past decades, substantial progress has been made in elucidating the cellular and molecular mechanisms of intestinal fibrosis. Here, we summarized new discoveries and advances of cellular components and major molecular mediators that are associated with intestinal fibrosis, aiming to provide a basis for exploring effective anti-fibrotic therapies in this field.
