She told me she was im－pressed by the student volunteers in two respects: First , all the students could speak very good English ; second, many of them know about Western culture and society, but when it came to some issues of Chinese culture, from time to time they stammered and stut－tered.

她告诉我，她对这些学生志愿者的印象主要有两个：一是所有学生的英语都说得很好；二是他们中有许多人对于西方的文化和社会情况都非常了解，但是每当提及中国文化的一些问题，他们却老是支支吾吾。

However, when volunteers generously placed their interests of others before their own by making charitable donations, another brain circuit was selectively activated: the subgenual cortex/septal region.

然而，当志愿者慷慨把自己的利益之前他人，使自己的慈善捐款，另一个大脑电路选择性激活：在subgenual皮质/间隔区域。

Conversely, they noticed the dots 23.5 milliseconds sooner in the positive images, such as cuddly puppies, than in the neutral ones, suggesting they were subliminally drawn to them.

相反地，这些志愿者找出正面图像，如可爱的小狗，中的黑点比找出中立图像中的黑点用时短23.5毫秒，表明他们潜意识里被正面图像吸引。

"Therefore, it's difficult to produce legislation on surrogacy bans."

Part II The experiment study on anti-tumour effect of dendritic cells derived from peripheral blood monocyte of patients with oral cancer after pulsed by tumour antigen in different ways. Collected 50ml peripheral blood from each patients and volunteers to induced DC in vitro. We parted the test group and control group into three subgroups respectively, untreated group A, freezed and thawn group B, RNA transfected group C. To group A, after induced DCs for five days , we added 200U/mlTNF-α in each hole and cultured on. To group B, we added protein antigen (DC/ tumor cells = 1 : 1 ,each hole) for 4h at 5d, and then added 200U/mlTNF-α in each hole and cultured on. To group C, transfected immature DC with tumor cell RNA(DC:RNA=1×105/ml: 5ug)at 5d, operated completely with the specification of invitrogen DMRIE-C reagents. After transfection we replaced transfection agent with complete medium, and then added 200U/mlTNF-α in each hole and cultured on.

第二部分口腔癌患者外周血来源的树突状细胞体外负载抗原后抑瘤作用的实验研究无菌采集20例口腔癌患者和20例健康志愿者外周血50ml，分离单个核细胞体外诱导培养DC，并将实验组和对照组细胞各分为三组，A组为未处理组，B组为冻融组，C组为RNA转染组。A组DC在培养5d后，每孔加入TNF-α200U/ml；B组DC培养第5d后，每孔中加入癌细胞蛋白抗原，使DC/肿瘤细胞=1：1，继续培养4h后，每孔加入TNF-α200U/ml；C组将培养至第5d的未成熟DC用肿瘤细胞RNA进行转染(DC：RNA=1×105/ml： 5ug，按照invitrogen DMRIE-C试剂说明书进行操作)，转染结束后用完全培基取代转染剂，每孔加入TNF-α200U/ml。

This new approach allowed us to measurethe dose-dependent release of histamine and tryptase from mastcells and the subsequent vascular and sensory effect withoutsystemic side effects in volunteers.

这种方法让我们可以在志愿者中测量巨细胞剂量依赖性的释放的组胺以及类胰蛋白酶的量，及其对血管和感觉的作用而不产生副作用。

Methods: The mucociliary transport rates of 30 patients with chronic hypertrophic rhinitis before and 3 and 6 months after the partial inferior turbinectomy and 10 healthy control subjects were detected by saccharin test.

用糖精法测定30例慢性肥厚性鼻炎患者术前、术后3个月及术后6个月和10例无鼻腔疾病志愿者作为对照组的鼻黏膜纤毛输送率。

RESULTS: Unmedicated major depressed patients had significantly decreased platelet [3H]-rauwolscine binding Bmax values compared to normal volunteers.

结果：与健康志愿者比，未用药的抑郁症患者血小板[3H]-α-育亨宾和Bmax 都显著降低，而[3H]-α-育亨宾的结合常数没有区别。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
