RESUMO
Objective:To explore the effect of nano-carbon in lymph node dissection for thyroid cancer.Methods:46 patients with thyriod cancer were randomly divided into treatment group and control group.The identification rate of lymph nodes,lymph node positivity and parathyroid function were compared after surgery.Results:Compare to the control group,the identification rate of lymph nodes in treatment group was higher (P＜0.05),but there was no significant difference on lymph node positivity (P＞0.05).what's more,patients with low blood calcium and parathyroid hormone in treatment group were less than that in control group after surgery (P＜0.05).The difference of severity of clinical symptoms was not statistically significant (P＞0.05).Conclusion:Nano-carbon increases the lymph node identification rate and reduces the risk of parathyriod injury in patients with thyroidectomy.
RESUMO
The objective of the study is to find out the effect of shark chondroitin on T lymphocyte subsets in cancer patients. Patients were divided into two groups. One group was treated with chemotherapy alone, and the other group was treated with chemotherapy plus shark chondroitin. Using immunofluorescence technique, T lymphocyte subsets in the peripheral blood were determined in two groups before and after chemotherapy. The results showed that CD4(+)/CD8(+) ratio increased in the patients received shark chondroitin. In the chemotherapy group, CD3(+) had no change, but CD4(+) decreased while CD8(+) increased significantly. The results suggest that shark chondroitin could enhance immune function in cancer patients, especially during chemotherapy.
