[Modulation of Chinese regimen granules of Shenyang on peripheral blood lymphocyte subsets of SD rats with SCC of tongue].

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.

[Modulation of Chinese prescription Shenyang on Th1/Th2 cytokines in serum of SD rats with squamous cell carcinoma of the tongue].

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.

[Immunodetections and analysis of peripheral blood for patients with oral cancer undergoing operation].

PURPOSE: To investigate the immunological function for patients with oral cancer undergoing operation. METHODS: Peripheral blood was taken from patients with oral cancer before and after operation. Proportions of CD3(+) total T, CD4(+) Th, CD8(+) Tc/Ts, CD19(+) total B, CD16(+)/CD56(+)NK were detected by flow cytometry (FCM). Detections of serum tumor necrosis factor alpha (TNF-alpha) and soluble interleukin-2 receptor (sIL-2R) were performed with enzyme-linked immunosorbent assay(ELISA). Paired t test was used for statistical analysis. RESULTS: The proportions of CD8(+)Tc/Ts, CD19(+) total B and CD4(+)/CD8(+) increased significantly after surgery. Post operative proportion of CD16(+)/CD56(+)NK decreased more significantly. The concentration of TNF-alpha was less than that before operation(P<0.05). CONCLUSIONS: Surgery could change immunological function and alleviate immunosuppression of oral cancer patients. Detections for immune conditions of oral cancer patients might have important clinical values in prognosis evaluation and guiding treatment, especially immunotherapy, after operation.

[Prognosis evaluation and statistical analysis].

With the progress of medical sciences, many new methods and protocols have been developed for clinical diagnosis and treatment. And evaluation of disease prognosis has been emphasized increasingly. Thus, choosing appropriate statistical parameters and analytic methods become more and more important for objective evaluation. This article reviews the parameters used in evaluation of patients' prognosis, influencing factors on prognosis, design of research on prognosis and statistical analysis. The causes for bias and problems needing attention in evaluation of prognosis are also discussed.

[The reconstruction of neovascularization of posterior pharyngeal flap: an experimental study in dogs].

OBJECTIVE: To elucidate the reconstruction of neovascularization that occurred in the superiorly and inferiorly based posterior pharyngeal flaps in different time postoperatively. METHODS: Ten mongrel dogs were randomly divided into two experimental groups, which were performed superiorly or inferiorly based posterior pharyngeal flap surgery respectively. Each group was then subdivided into five subgroups, and were sacrificed immediately after operation or on 3, 7, 30, 90 day postoperative respectively. Microangiography was used to exhibite the vessel. RESULTS: 1. The blood vessel reconstruction of the superiorly based posterior pharyngeal flap was more rapid compared with the inferiorly based flap. The 3-day flap has established an axial vascular network, which was mature on the 30-day flap. The superiorly based posterior pharyngeal flap was mainly supplied by the pedicle. 2. The blood vessels reconstruction of the inferiorly based posterior pharyngeal flap was firstly occurred in the pedicle and apex of the flap, which grew slowly to the middle of the flap. The inferiorly based posterior pharyngeal flap was supplied by the pedicle and the soft palate. A mature axial vascular network was exhibited on the 90-day flap, which was not mature on the 30-day flap. CONCLUSION: Both superiorly and inferiorly based posterior pharyngeal flap can establish an axial vascular network and gain ample blood supply.
