The unique properties of self-healing materials hold great potential in the field of biomedical engineering. Although previous studies have focused on the design and synthesis of self-healing materials, their application in in vivo settings remains limited. Here, we design a series of biodegradable and biocompatible self-healing elastomers (SHEs) with tunable mechanical properties, and apply them to various disease models in vivo, in order to test their reparative potential in multiple tissues and at physiological conditions. We validate the effectiveness of SHEs as promising therapies for aortic aneurysm, nerve coaptation and bone immobilization in three animal models. The data presented here support the translation potential of SHEs in diverse settings, and pave the way for the development of self-healing materials in clinical contexts.
Hyperfibrinogenemia has been reported to be a predictor of poor prognosis in cancer patients, and in hepatocellular carcinoma (HCC) patients, survival remains uncertain and unpredictable. The aim of the present study was to evaluate the association between the level of plasma fibrinogen and overall survival in HCC patients.Overall, 308 patients with histologically proven HCC were included in our study. Univariate and multivariate analyses were performed to identify predictive risk factors for the rates of overall survival and tumor recurrence.Patients in the high-fibrinogen-level group were more likely to have advanced stage HCC, portal vein invasion, and tumors that were greater in number and larger in diameter than were patients in the low-fibrinogen-level group (all P < .05). The long-term overall survival rate of patients in the high-fibrinogen group was much lower than that of patients in the normal-fibrinogen group (P = .008), and similar outcomes were observed in the subgroup of patients who underwent radical therapies for HCC (P = .003). The results of the univariate and multivariate analyses indicated that high plasma fibrinogen remained independently associated with poorer overall survival. In addition, high plasma fibrinogen levels were associated with nonresponse to transarterial chemoembolization (TACE) (P < .001).Elevated plasma fibrinogen was independently associated with advanced HCC stage, poor prognosis, and nonresponse to TACE and may, therefore, serve as a valuable clinical biomarker for predicting prognosis in HCC patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
