Under the influence of oncogenic signals and abnormal metabolism, the redox status of cancer cells often differs from that of the normal cells, manifesting as elevated generation of reactive oxygen species( ROS) and oxidative stress.Many signaling pathways involved in tumorigenesis can directly or indirectly regulate ROS metabolism.Currently, the biological significance of increased ROS in cancer cells is still somewhat controversial.ROS on the one hand can promote cancer development and drug resistance, and on the other hand can also cause cell injury and even cell death.To maintain cell viability and proliferation, cancer cells usually up-regulate their antioxidant capacity in adaptation to the intrinsic oxidative stress.Such adaptive mechanisms to oxidative stress are highly important in both cancer development and also play a major role in cancer cell response to therapy.Compelling evidences from recent studies have suggested that targeting the redox regulation mechanisms through proper intervention strategies may have significant therapeutic implications in cancer treatment.This article will focus on alterations of redox status in cancer cells, their adaptation to oxidative stress, and the underlying mechanisms.Potential therapeutic strategies based on such biochemical characteristics of cancer cells will also be discussed.

Objective:To discuss the influence of bifid triple viable enteric-coated capsules on liver function and inflammatory fac-tor in the patients with non-alcoholic steatohepatitis ( NASH) . Methods:Totally 70 cases of patients with NASH were selected and di-vided into the control group and the observation group at random. The patients in the two groups were all given routine hepatoprotective therapy. The patients in the observation group were additionally given 420mg bifid triple viable enteric-coated capsules, three times a day for 4 weeks. Except for bifid triple viable enteric-coated capsules, the patients in the control group were given the same medical treatment as that in the observation group. The changes of liver function index, serum high sensitivity C reaction protein ( hs-CRP) , IL-6 and IL-8 levels in the two groups before and after the medical treatment were observed and the security was compared. Results:After the 4-week medical treatment, ALT, GGT, serum hs-CRP, IL-6 and IL-8 levels in the two groups were obviously declined than those before the treatment (P<0. 05 or P<0. 01), and the declining rate in the observation group was much higher than that in the control group (P<0. 05). Totally 6 and 4 cases of adverse drug reaction (ADR) respectively appeared in the observation group and the control group during the medical treatment with mild symptom, and the difference was without statistical significance (P>0. 05). Conclusion:Bifid triple viable enteric-coated capsules in the treatment of NASH can obviously reduce the serum hs-CRP, IL-6 and IL-8 levels, inhibit the intrahepatic inflammation and immunologic injury, and improve the liver function index with high security.

The purpose of this study was to evaluate the effect of bone marrow mesenchymal stem cells (MSCs) transfected with the basic fibroblast growth factor (bFGF)-expressing recombinant adeno-associated virus vector (rAAV2-bFGF), on early angiogenesis of calvarial defects in rats. The MSCs were cultured and transfected with rAAV2-bFGF after differential adherence isolation. The transfection efficiency was detected by RT-PCR and Western blotting. The transfected MSCs were compounded with poly-DL-lactide/hydroxyapatite (PDLLA/HA) in vitro. The cranial defect models in 36 male SD rats were created. Nothing (group A), PDLLA/HA alone (group B), PDLLA/HA combined with MSCs (group C), and PDLLA/HA combined with rAAV2-bFGF transfected MSCs (group D) were implanted in rat calvarial defects. The specimens were harvested for hematoxylin-eosin staining on the day 1, 3 and 7 after implantation. Factor VIII immunohistochemical staining and histomorphometric analysis were carried out to evaluate neovascularization around the implantation. The results indicated that MSCs could indeed be successfully transfected with the rAAV2-bFGF vector. Histological and histomorphometric analysis revealed that the angiogenesis in group D was significantly enhanced as compared with the rest groups (P<0.05). These results strongly suggest that MSCs transfected with rAAV2-bFGF in combination with PDLLA/HA can effectively promote the early angiogenesis of calvarial defects in rats, which played an important role in creating an environment suitable for the survival and activity of transplanted cells for further applications in cranio-maxillofacial bone regeneration.
