Objective To explore the clinical value when treating cervical cancer of supplementing radiotherapy with hyperbaric oxygen treatment. Methods Fifty-eight cervical cancer patients were randomly divided into 2 groups; the HBO group (n=28) received radiotherapy combined with hyperbaric oxygen treatment; a control group (n = 30) received only radiotherapy. Results The complete response rate (CR) of the HBO group was 75.0% , the partial response rate (PR) was 7.1% ,the effective rate(CR + PR) was 92.8% , the total 3 year survival rate was 71.4% , the local recurrence rate was 10.7% , and all of these results were significantly different from the controls (P

Vitamin C is a well-known antioxidant with antiviral, anticancer, and anti-inflammatory properties based on its antioxidative function. Aptamin C, a complex of vitamin C with its specific aptamer, has been reported to maintain or even enhance the efficacy of vitamin C while increasing its stability. To investigate in vivo distribution of Aptamin C, Gulo knockout mice, which, like humans, cannot biosynthesize vitamin C, were administered Aptamin C orally for 2 and 4 weeks.The results showed higher vitamin C accumulation in all tissues when administered Aptamin C, especially in the spleen. Next, the activity of natural killer (NK) cells were conducted. CD69, a marker known for activating for NK cells, which had decreased due to vitamin C deficiency, did not recover with vitamin C treatment but showed an increasing with Aptamin C. Furthermore, the expression of CD107a, a cell surface marker that increases during the killing process of target cells, also did not recover with vitamin C but increased with Aptamin C. Based on these results, when cultured with tumor cells to measure the extent of tumor cell death, an increase in tumor cell death was observed. To investigate the signaling mechanisms and related molecules involved in the proliferation and activation of NK cells by Aptamin C showed that Aptamin C treatment led to an increase in intracellular STAT3 activation. In conclusion, Aptamin C has a higher capability to activate NK cells and induce tumor cell death compared to vitamin C and it is mediated through the activation of STAT3.
