Background： Although emerging evidence points to benefits from Tai Chi Chuan （TCC） in improving immune system function, its effects on cellular immune responses remain under-studied. The objective of this study was to evaluate the effects of TCC training on cellular immunity in non-small cell lung cancer patients. Methods： A 2-group randomized trial design in which post-surgical, non-small cell lung cancer survivors were randomly assigned to a TCC training group （n = 16） or a control group （n = 16）. The participants in the TCC group completed a 16-week intervention. The main immune response outcome measures assayed included the ratio of T-helper cells/T-suppressor cells （CD4＋：CD8＋ ratio） and complement regulatory proteins status （CRPs; CD55 and CD59）. Using repeated measures ANOVA, the data were analyzed for the participants who completed the study （n = 27）. Results： At 16 weeks, the TCC participants showed a significantly lower increment in the expression of CD55 （p 〈 0.05） as compared to the control group. No significant between-group differences were found in the CD4＋：CD8＋ ratio or CD59 expression. There were also no significant correlations among the changes in CRPs or T lymphocyte subpopulations, either. Conclusion： A 16-week TCC intervention caused no alterations in CD4＋：CD8＋ ratio, but significantly attenuated CD55 expression among post- surgical non-small cell lung cancer survivors.

我国反垄断法即将出台,学界要求控制行政性垄断的主张基本上已达成共识,对如何控制行政性垄断还存在着较大分歧,但这些分歧均未涉及在思想上统摄全局的“镇心剂”———行政性垄断控制的法理念。正是基于此目的,从行政主体的角度来探讨控制行政性垄断要求行政主体所持的法理念需及时归位,即行政主体对控制行政性垄断需着眼于社会产出最大化责任者的角度来维护市场的自由竞争秩序,方能有效地控制行政性垄断和实现社会整体经济利益之目的。

破产和解制度作为破产企业再建型程序之一,与破产重整制度、破产清算制度并列为企业破产法律制度中的三大支柱性制度。然而,自中国现行企业破产法实施以来,破产和解制度尚未发挥出其应有的功能,直接导致了破产和解制度在法律价值、制度规范与司法实践之间的分离。有鉴于此,在肯定破产和解制度法律价值的前提下,有必要对破产和解制度的制度规范进行深度反思,进一步改进破产和解制度的监督机制,并创设破产和解制度与破产重整制度、破产清算制度之间的转换机制,以增强破产和解制度在司法实践中的可接受度与可操作性,从而真正确保破产和解制度在法律价值、制度规范与司法实践上的统一。
