ABSTRACT
Ulcerative colitis (UC) is a difficult intestinal disease characterized by inflammation, and its mechanism is complex and diverse. Angiopoietin-like protein 2 (ANGPT2) plays an important regulatory role in inflammatory diseases. However, the role of ANGPT2 in UC has not been reported so far. After exploring the expression level of ANGPT2 in serum of UC patients, the reaction mechanism of ANGPT2 was investigated in dextran sodium sulfate (DSS)-induced UC mice. After ANGPT2 expression was suppressed, the clinical symptoms and pathological changes of UC mice were detected. Colonic infiltration, oxidative stress, and colonic mucosal barrier in UC mice were evaluated utilizing immunohistochemistry, immunofluorescence, and related kits. Finally, western blot was applied for the estimation of mTOR signaling pathway and NLRP3 inflammasome-related proteins. ANGPT2 silencing improved clinical symptoms and pathological changes, alleviated colonic inflammatory infiltration and oxidative stress, and maintained the colonic mucosal barrier in DSS-induced UC mice. The regulatory effect of ANGPT2 on UC disease might occur by regulating the mTOR signaling pathway and thus affecting autophagy-mediated NLRP3 inflammasome inactivation. ANGPT2 silencing alleviated UC by regulating autophagy-mediated NLRP3 inflammasome inactivation via the mTOR signaling pathway.
ABSTRACT
Studies have shown that Chinese herb caulis extract can effectively inhibit the expression of the core regulatory hormone hepcidin in iron metabolism and significantly increase the iron level in the body. On this basis, this paper analyzed clinical efficacy and safety of oral niferex [polysaccharide iron complex] combined with caulis Decoction in the treatment of iron deficiency anemia. The results showed that the recovery rate of the Caulis group, Niferex group and the combined treatment group were 41.6%, 46.6% and 58.3% respectively. The difference of recovery rate was statistically significant. The RBC, Hb, Hct, SI, SF, Tf, TIBC and serum Hepcidin in the combined treatment group were
significantly higher than those in the other groups [P<0.05]. Caulis group has 3 cases of gastrointestinal symptoms, and the incidence of adverse reactions was 5%. Chinese medicine caulis can significantly improve erythrocyte count,
hemoglobin, hematocrit and related iron metabolism, but the improvement of the combined treatment group is more obvious. In conclusion, Chinese medicine caulis can significantly improves the clinical symptoms and iron metabolism
in patients with iron deficiency anemia, combined oral niferex therapy has better effect
