RESUMEN

PURPOSE: Prospective research demonstrated that Chinese prescription Shenyang could prolong the survival time and improve the survival rate of patients with oral squamous cell carcinoma (SCC). But the mechanism was not clear. The purpose of this study was to investigate effect of Shenyang on the level of Th1/Th2 cytokines in serum of SD rats with SCC of tongue and clarify its mechanism. METHODS: Among 80 SD rats fed by 0.002% 4-nitroquinoline-1-oxide (4NQO) drinking water for 36 weeks, 61 with SCC of tongue had been found and randomly divided into 4 groups, namely Shenyang A, Shenyang B, positive and negative control group. Before and after high and low dosage of Shenyang, acanthopanax senticoside and water had been given for 15 days respectively, peripheral blood serum was collected. Secretion of Th1-type cytokines, such as IFN-gamma, IL-2, TNF-alpha and Th2-type cytokines, such as IL-4, IL-10 were detected by enzyme-linked immunosorbent assay (ELISA). Statistical analysis was made with paired t test. RESULTS: Shenyang significantly enhanced ,the serum levels of Th1-type cytokine, TNF-alpha and IL-2 (P<0.05), and decreased the expression of Th2-type cytokine, IL-4 and IL-10(P<0.05). Serum IFN-gamma had been increased to some extent. CONCLUSION: Reversing Th2 to Th1 cytokines and then enhancing the immunity may be one of the mechanisms in anti-tumor effect of Shenyang.

RESUMEN

OBJECTIVE: Prospective research demonstrated that Chinese regimen granules of Shenyang could prolong survival time and improve survival rate of patients with oral squamous cell carcinoma (SCC). But the mechanism was not clear. The purpose of this study was to investigate Shenyang's effect on peripheral blood lymphocyte subsets of SD rats with SCC of tongue and explore immunological mechanism. METHODS: Among 80 SD rats fed by 0.002% 4-nitroquinoline-1-oxide (4NQO) drinking water for 36 weeks, 61 rats with SCC of tongue had been found and were randomly divided into 4 groups, namely Shenyang A, Shenyang B, positive and blank control groups. Before and after high and normal dosage of Shenyang, acanthopanax senticoside and water had been given for 15 days respectively, peripheral blood lymphocyte subsets were detected with flow cytometry. The data were statistically analyzed with paired t Test. RESULTS: Percentage of CD3+ CD4+ T cell and CD3-CD161a+ NK cell, ratio of CD4+/CD8+ were increased. Percentage of CD3+CD8+ T cell was decreased, and the effect was better than that of acanthopanax senticoside in improving the percentage of CD3-CD161a+ NK cell. CONCLUSION: Among anti-tumor mechanisms of Shenyang it is that corrects disorder of lymphocyte subsets and increases percentage of CD3-CD161a+ NK cell.

RESUMEN

OBJECTIVE: To evaluate the long term therapeutic effect of Chinese prescription "Shen Yang" in the combined and sequential therapy for oral squamous cell carcinoma cases. METHODS: There are 238 cases with oral squamous cell carcinoma. They were divided into two groups randomly as "Shen Yang" experiment group and control group (placebo). 25 cases were precluded from the experiment group. 17 of them were due to unexperiment of taking "Shen Yang" within three months. 8 cases were lost of follow-up. 213 patients were included in this study. Among them, 104 cases in experiment group, and 109 cases in control one. Patients in both groups were followed-up for 5-10 years. Their life-curve was calculated by means of Logrank method. RESULTS: The survival rate of "Shen Yang" group was improved by 8.46%, 9.26%, 9.04% and 8.57% for 3-year, 5-year, 8-year and 10-year survival rates. But the differences between the two groups were not statistically significant (P=0.1936, P>0.05). CONCLUSION: Chinese prescription of "Shen Yang" had a tendency to improve the survival rate for oral squamous cell carcinoma patients.
