Gua Sha- An Ancient Technical Management- for Certain Illness

We were attracted by a news in Washington Post talking about the effects of Gua Sha(刮痧) on pain relief in the United States.Once there was a film telling culture conflicts between Eastern and Western world derived from Gua Sha in 2000,in which the Chinese parents were sued as child abuse evidenced by the appearance of petechiae and ecchymosis(Sha) on the child’s back.Now about 12 years later Gua Sha has been one of the complementary therapies widely accepted in the United States mirrored by more and more clinic-visits and several evidence-based studies published in peer-reviewed journals.     

人脐血单个核贴壁细胞与胃癌细胞的共培养：最适效靶比筛选***☆

背景：近年来大量研究关注脐血细胞可能对肿瘤细胞有杀伤和抑制作用，人们尝试利用脐血细胞移植抑制和杀伤肿瘤细胞，这为临床医生们提供了抗癌的新途径。 目的：探讨人脐血单个核细胞与肿瘤细胞体外共培养后，对肿瘤细胞的抑制作用。 方法：采用密度梯度离心的方法分离人脐血单个核细胞，流式检测细胞表面Marker表达，将单个核细胞与胃癌细胞进行共培养，倒置显微镜观察两种细胞共培养后细胞形态的变化，采用了乳酸脱氢酶法检测对肿瘤细胞的抑制作用，找出抗肿瘤细胞效果最好的效靶比。 结果与结论：加入脐血的贴壁单个核细胞贴壁细胞2 d后，肿瘤细胞的脱落明显，贴壁细胞实验组肿瘤细胞排列不规整，细胞密度低。酸脱氢酶法显示部分脐血贴壁细胞确有较强的抗肿瘤能力，但个体间抗肿瘤的能力差异较大，最大可相差4倍。脐血单个核贴壁细胞对肿瘤细胞有直接的杀伤作用，其最适的效靶比为2:1。
