Objective To discuss the effects of resistant starch (RS ) on metabolism of type 2 diabetes mellitus (T2DM ) . Methods The databases of Pubmed ,Ovid ,Embase and Cochrane Library were retrieved for search the randomized controlled trials (RCTs) on RS intervention on T2DM .The retrieval time was until June 21 ,2016 .The literature quality was assessed by using the bias risk evaluation tool recommended by Cochrane collaboration net .The related data were integrated and analyzed by using the Stata 12 .0 software .Results A total of 909 articles were retrieved out ,in which 6 articles met the included criteria and 308 cases were included as the research subjects .All the studies demonstrated that fasting blood glucose(FBG) in the patients with T2DM was decreased significantly after RS intervention .Four studies detected postprandial blood glucose and considered that postprandial glucose was decreased significantly after RS intervention (P=0 .023 ,P=0 .010 ,P<0 .05 ,P=0 .045) .Three studies .reported the related data of fasting total cholesterol(TC) and triglyceride(TG) ,but the study results were greatly different from each other .3 stidies indicated that compared with control group ,the HDL-C level of the RS group was significantly increased (P<0 .05) ,while the level of LDL-C had no obvious difference .In Bodinham′s .study ,HDL-C and LDL-C had no obvious difference between the two groups .The study by Gargari′s and Bodinham′s .thought the level of TNF-αin the RS group was significantly decreased (P<0 .05 , P=0 .013) ,however ,the former thought that the level of IL-6 in the RS group was also decreased ,while the latter thought that compared with the control group ,the IL-6 level had no significant difference .Conclusion RS can increase insulin sensitivity inT2DM patients ,and improves glucolipid metabolic disorder .

The self-healing microcapsule material is one of the smart materials that can self-identify and self-heal microcracks. Adding microcapsules to dental resin composites can resist generation of microcracks and prolong service life of resin restorations. In this literature, the overview of self-healing microcapsule materials, the combined application of self-healing microcapsule materials and other modified materials, the silanization treatment of dental self-healing microcapsules, the dynamic mechanics, fatigue and aging studies on self-healing dental resins were comprehensively presented and reviewed. In addition, prospects of dental self-healing microcapsule materials were also discussed.
