Temperature-sensitive hydrogel for rectal perfusion improved the therapeutic effect of Kangfuxin liquid on DSS-induced ulcerative colitis mice: The inflammation alleviation and the colonic mucosal barriers repair. Int J Pharm 2020; 589:119846. [PMID: 32891717 DOI: 10.1016/j.ijpharm.2020.119846] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Revised: 08/19/2020] [Accepted: 08/31/2020] [Indexed: 01/05/2023]
Abstract
Kangfuxin liquid (KFX) is a Chinese medicine extracted from Periplaneta americana dried worms, which presented the bioactive functions of anti-inflammation and promoting the gastrointestinal mucosal barriers repair. But the low availability of KFX exposed to the distal colon affects its therapeutic effect on ulcerative colitis. Herein, an in situ hydrogel containing KFX was designed by using temperature-sensitive poloxamer 407 (P-407) as material for rectal administration. Three KFX-P formulations with different P407 concentrations (17%, 20% and 25%) were designed and screened by detecting the gelation time, gelation temperature and mechanical strength of hydrogel. P407 in these formulations was able to be completely dissolved in KFX at 4 ℃ and then was in situ gelled at 37 ℃ to form a semisolid hydrogel. Moreover, the gelation time, the gelation temperature and the mechanical strength of KFX-P hydrogel are highly dependent on P407 concentration. With P407 concentration increasing, both the gelation time and gelation temperature of KFX-P accordingly decreased and the gelation temperature range becomes narrowed; while the mechanical strength increased. KFX-P-20% displayed the moderate gelation temperature (28-30 ℃), the short gelation time (26 s) and the moderate mechanical strength (G' = 4.2 × 103 Pa), which was chosen for animal study. Thereafter, ulcerative colitis mice model (UC) was established by dextran sulfate sodium (DSS) and the therapeutic effect of KFX-P on UC was evaluated by inflammation symptoms relief, colon length, colonic MPO level and colonography. After rectal administration of KFX or KFX-P, the symptoms including diarrhea and hematochezia (DAI scores), weight loss and spleen swelling were significantly hindered. Meanwhile, the colonic MPO level in these groups was significantly decreased in comparison with PBS treatment. But the therapeutic effect of KFX-P was better than KFX. Besides, the morphology and mucosal barrier of colon were evaluated by HE staining, ZO-1 and claudin-5 staining. The mucosa epithelium layer, crypt, muscle layer mucosa and submucosa were also well repaired after KFX-P treatment. The strong fluorescence of ZO-1 and claudin-5 were uniformly distributed along the whole epithelial mucosa after KFX-P treatment, indicating the effective repairing of the colonic mucosal barrier. Collectively, the temperature-sensitive KFX-P for rectal delivery could effectively promote the repair of the colon mucosal barrier and inhibit the colonic inflammation in DSS-induced mice, which may be a potential strategy for UC treatment.

Abstract
Implantation of acellular biomimetic scaffolds with proangiogenic motifs may have exciting clinical utility for the treatment of ischemic pathologies such as myocardial infarction. Although direct delivery of angiogenic proteins is a possible treatment option, smaller synthetic peptide-based nanostructured alternatives are being investigated due to favorable factors, such as sustained efficacy and high-density epitope presentation of functional moieties. These peptides may be implanted in vivo at the site of ischemia, bypassing the first-pass metabolism and enabling long-term retention and sustained efficacy. Mimics of angiogenic proteins show tremendous potential for clinical use. We discuss possible approaches to integrate the functionality of such angiogenic peptide mimics into self-assembled peptide scaffolds for application in functional tissue regeneration.

Abstract
BACKGROUND In patients with ulcerative colitis (UC), the repeated cycle of injury and repair of intestinal mucosa has been reported to increase the risk of colon cancer. So, a safe and efficient therapy is required for the treatment and prophylaxis for the disease.This study aims to investigate the efficacy of Calendula officinalis extract in treatment of experimentally induced ulcerative colitis in dog animal model. METHODS During fall 2010, 10 out-bred female German dogs (1-2 years old; weighs of 20-25 kg) were enrolled. Ulcerative colitis was induced with 6% acetic acid as enema and method of treatment was retrograde (via enema) too by C. officinalis. RESULTS Loose stools, diarrhea, gross bleeding and loss of body weight happened after administration of acetic acid and crypt damage, loss of epithelium, infiltration of inflammatory cells and depletion of goblet cells were noticed histologically. C. officinalis could successfully resolve the damages of UC. CONCLUSION Treatment with C. officinalis can broaden the current therapy options for UC.
