Operation: First of all, the performer holds the back up of beneficiary's hand with both four fingers and pressing on both big and small "Yu Ji" point with both thumbs and pushing along with both "Yu Ji" to the tips of little finger and thumb for six times and then holds the wrist with one hand to press from both sides with thumb and forefingers and another hand to hold and to push the joints of fingers of beneficiary to smooth out and shake from the root to the top of the fingers.

操作：首先用两手四指托扶住受术者掌背，用大拇指分别压在掌根大小鱼际处，同时沿大小鱼际方向向指尖处分推6次；再用一只手托住其腕，另一只手的拇指指腹与食指夹合，着力推捏受术者的指关节，自指根捋抖到指端。

Methods 30 patients with benign breast tumor, 30 patients with malignant breast tumor underwent color Doppler sonography 1 week prior to surgical operation, and the sizes and sites of tumor masses, color gradings of blood flow and hemodynamic parameters of the lateral thoracic artery and axillary artery were measured and recorded, with 25 healthy women as the control group.

术前1周对30例乳腺良性肿块患者、30例乳腺恶性肿块患者及25例健康女性进行彩色多普勒超声检查，测量并记录肿块大小、部位、彩色血流分级及胸外侧动脉和腋动脉阻力指数。结果乳腺癌组肿块大小2～6 cm，腋动脉、胸外侧动脉RI与良性组和对照组相比明显降低（P.05或P.01）。

一个很典型的例子就是DNA分子大小的测量：在凝胶电泳出现之前，DNA分子大小是用蔗糖密度梯度沉降法来测量的，这一方法费时费力而且花费昂贵；而在梯度沉降法出现之前，使用的是黏度法。

As PTDT does in threshold traits, PTDT is valid not only for different QTL effect level, but also for maker with multiple alleles and multiple tightly linked markers.(2) Under an appropriate selection ratio s (in this study, s is 0.2, 0.4, 0.6, 0.8, respectively), the power of PTDT can be improved and the genotying individuals can be decreased using selective genotyping design. However, the power of PTDT is related with population size and population structure, an appropriate selection ratio can be defined by simulation based on the existing data.(3) Among the three transforming methods, mixed-family selection is the best, full-sib selection has same power to mixed-family selection in many parameter combinations, and Estimated Breeding Value selection is inferior to them.

数量性状QTL定位的模拟研究结果表明：(1)数量性状经有效转化后，PTDT对数量性状QTL定位保持了阈性状QTL定位的稳健与高效，对不同效应大小的QTL(10％，30％，50％)PTDT都是一个有效的分析方法；(2)在多等位基因标记、多标记方面，PTDT的检验功效与阐性状分析时一样高效；(3)在合适的选择率下(本研究的分别为0.2，0.4，0.6，0.8，1.0)，选择性基因型测定不仅可以减少基因型测定的数量，而且可以提高PTDT的检验功效，但选择性基因型测定的PTDT检验功效很大程度上与群体大小和结构有关，这个可根据具体情况通过模拟找到一个合适的选择率；(4)三种转化方法的转化效力结果表明，家系内混合家系选择的转化效力最高，家系内全同胞选择次之，估计育种值选择的转化效力较差。

In certain range,the bioenrichment of the mealworm larvae to Zinc in reference to the dosage added in the fodder is accorded with cubic curve relation:Y=181.2517+20.9314X-0.4099X2+ 0.0025X3. And the enrichment ability of T. molitor larvae in reference to the weight is also accorded with the cubic model:Y=35.8325+61.4155X-10.2980X2+0.4434X3. The enrichment of the larvae to Zinc can get to a high level in 2 to 3 days. This is anadvantage to numerous rearing of the mealworm. But we do not find a good rearing way to enhance the rate of bioenrichment to Zinc. And the further research about this is anticipated.

第二部分：采用锌作为添加元素，考查黄粉虫对微量元素的富集规律，结果表明：(1)黄粉虫虫体锌含量在一定范围内随锌添加量增加而呈三次曲线关系，符合三次曲线方程：Y=181.2517+20.9314X-0.4099X~2+0.0025X~3；(2)黄粉虫幼虫对锌富集能力随虫体大小变化而变化，与虫大小亦呈三次曲线关系；Y=35.8325+61.4155X-10.2980X~2+0.4434X~3；(3)黄粉虫虫体锌含量随着锌饲料添加而迅速上升，可在短期2～3天内达到较高水平，对于以黄粉虫为材料进行富锌保健食品生产有很大优越性；(4)本试验并未找到一种较好的锌添加方法来提高锌富集量，这方面的研究有待继续。
