Jianpi Bushen Qingchang Huashi Decoction combined with BMSCs for repairing intestinal barrier in a rat model of ulcerative colitis

AIM: To observe the effect of traditional Chinese compound medicine Jianpi Bushen Qingchang Huashi Decoction combined with bone mesenchymal stem cells (BMSCs) in the repair of the intestinal mucosa of rats with ulcerative colitis.

METHODS: Rats were divided into five groups: a normal group, a model group, a BMSCs group, an intervened BMSCs group and a combination group. The rats of the normal and model groups received an intravenous injection of normal saline separately through the tail vein. The BMSCs group received an intravenous injection of BMSCs (1 × 10⁶/mL) through the tail vein. The intervened BMSCs group and combination group received BMSCs (1 × 10⁶/mL) intervened by decoction in vitro, and the combination group additionally received the oral decoction for 10 d. Five rats were killed on the 5^th and 10^th day after the transplantation, respectively. The mRNA and protein expression of Muc2 was detected by real-time PCR and Western blot, respectively. Expression of Math1 and KLF-4 was assayed by Western blot.

RESULTS: The number of goblet cells was increased in each BMSCs transplantation group. The mRNA expression of Muc2 significantly increased in each treatment group relative to the model group, and the increase was more significant in the combination group than in the intervened BMSCs and BMSCs groups. As time increased, the therapeutic effect was more obvious. On the 10^th day of treatment, compared with the normal group, Muc2, Math1 and KLF-4 protein expression was significantly decreased in the model group, while the expression of these proteins was higher in the treatment groups, with the combination group increasing most obviously.

CONCLUSION: Transplantation of BMSCs combined with traditional compound Chinese medicine could improve the mRNA and protein expression of Muc2 in UC rats, reduce inflammation and repair intestinal barrier, which may be related to the Math1 and KLF-4 factors.

Role of ginsenoside in treatment of inflammatory bowel disease

Inflammatory bowel disease mainly includes Crohn's disease and ulcerative colitis, and its etiology and pathogenesis are still not very clear. So far, there has been no cure for this disease. In recent years, it has been found that ginsenoside has anti-inflammatory effects and can promote cell proliferation. In this paper, we review the role of ginsenoside in the treatment of inflammatory bowel disease.
