To review the recent progress of the small intestinal submucosa (SIS) in application research of tissue repair and reconstruction. The domestic and international articles on the SIS were reviewed and summarized. As a natural extracellular matrix, SIS has outstanding biological advantages, such as good mechanical property, tissue compatibility, and lower immunogenicity. SIS has been used to repair and reconstruct various types of tissue defects in animal models and clinical application, especially in the treatment of hernia, urinary system disease, and refractory skin trauma. The development of the tissue engineering technology expands the field of SIS repair and reconstruction and promotes the intensive study of SIS. However, the long-term effect of SIS in tissue repair and reconstruction still remains to be further observation, while the cell/SIS material construction by tissue engineering technology also needs more studies. SIS has a widely promising application future in the tissue repair and reconstruction.

We have studied the nonlinear optical absorption and the nonlinear optical rectification of an exciton in a nanoring in the presence of magnetic flux. The calculation results show that one can control the properties of nonlinear optical absorption and nonlinear optical rectification of a nanoring by tuning the outer and inner radius. Moreover, we find that the nonlinear optical properties of a nanoring can be modulated by the magnetic flux through the nanoring. © 2011 IOP Publishing Ltd.

Optical properties of a two-dimensional quantum ring with pseudopotential in the presence of an external magnetic field and magnetic flux have been theoretically investigated. Our results show that both of the pseudopotential and magnetic field can affect the third non-linear susceptibility and oscillator strength. In addition, we found that the oscillator strength and the absolute value of the resonant peak of the linear, non-linear and total absorption coefficient demonstrates the Aharonov-Bohm oscillation with magnetic flux, moreover, changes in confinement potential can influence the Aharonov-Bohm oscillation in peak while the resonant peak value of the linear, non-linear and total refractive index changes decreases as magnetic flux increases. © 2011 Elsevier B.V.

Glucose regulated protein 78 (GRP78) has been reported to be present on cell membranes of cancer cells but not the normal cells, serving as a potential anti-cancer target. In the present study, a fusion protein containing the GRP78 binding peptide WIFPWIQL and the active fragment of mung bean trypsin inhibitor was constructed, and its targeted anti-tumor effects were investigated both in vitro and in vivo. The results showed that the fusion protein specifically inhibited growth and induced apoptosis in colorectal cancer cells but not in the normal cells. Mechanistically, these anti-tumor effects were attributed to induction of G1 phase arrest and activation of multiple apoptotic pathways. Importantly, the fusion protein could also suppress the growth of xenografted human colorectal carcinoma in vivo. Our study reveals that this fusion protein may be developed as a therapeutic agent for treatment of colon cancer, and holds important implications for developing other anti-cancer peptide drugs. © 2013 Elsevier B.V.
