Abstract

Ischemia-induced adhesion is very common after surgery, and leads to severe abdominal adhesions. Unfortunately, many existing barrier agents used for adhesion prevention have only limited success. The objective of this study is to evaluate the efficacy of biodegradable and thermosensitive poly(ε-caprolactone)-poly(ethylene glycol)-poly(ε-caprolactone) (PCL-PEG-PCL) micelles for the prevention of postoperative ischemia-induced adhesion. We found that the synthesized PCL-PEG-PCL copolymer could self-assemble in an aqueous solution to form micelles with a mean size of 40.1 ± 2.7 nm at 10°C, and the self-assembled micelles could instantly turn into a nonflowing gel at body temperature. In vitro cytotoxicity tests suggested that the copolymer showed little toxicity on NIH-3T3 cells even at amounts up to 1,000 μg/mL. In the in vivo test, the postsurgical ischemic-induced peritoneal adhesion model was established and then treated with the biodegradable and thermosensitive micelles. In the control group (n=12), all animals developed adhesions (mean score, 3.58 ± 0.51), whereas three rats in the micelles-treated group (n=12) did not develop any adhesions (mean score, 0.67 ± 0.78; P<0.001, Mann-Whitney U-test). Both hematoxylin and eosin and Masson trichrome staining of the ischemic tissues indicated that the micelles demonstrated excellent therapeutic effects on ischemia-induced adhesion. On Day 7 after micelle treatment, a layer of neo-mesothelial cells emerged on the injured tissues, which confirmed the antiadhesion effect of the micelles. The thermosensitive micelles had no significant side effects in the in vivo experiments. These results suggested that biodegradable and thermosensitive PCL-PEG-PCL micelles could serve as a potential barrier agent to reduce the severity of and even prevent the formation of ischemia-induced adhesions.

Attention Score in Context

This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 February 2014.
All research outputs
#1,785,770
of 4,507,280 outputs
Outputs from International Journal of Nanomedicine
#278
of 1,146 outputs
Outputs of similar age
#42,322
of 124,304 outputs
Outputs of similar age from International Journal of Nanomedicine
#31
of 129 outputs
Altmetric has tracked 4,507,280 research outputs across all sources so far. This one has received more attention than most of these and is in the 58th percentile.
So far Altmetric has tracked 1,146 research outputs from this source. They receive a mean Attention Score of 1.8. This one has gotten more attention than average, scoring higher than 69% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 124,304 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 63% of its contemporaries.
We're also able to compare this research output to 129 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 65% of its contemporaries.
