Results: GINaTK retroviral vector containing HSV-tk was constructed and transduced into PA317 retrovirus packaging cell by lipofectin (named PA317TK). Rat glioma cell C6 was infected by the deficiency recombinant retrovirus (named C6TK). The sensitivity of C6TK cells to GCV or ACV increased 450 or 10 times than that of C6 cells respectively. Rat C6 glioma model was successfully built, and SD rats inoculated intracerebrally C6TK cells had normal gliomas. The average survival periods of the rats were about 15 days. However, after treated with ACV, the growth of C6TK tumors obviously regressed, and the survival periods extended to 57.8±8.1 days, especially in rats injected with mixed PA317TK and C6 cells or in situ PA317TK cells, which the tumors nearly disappeared after ACV administration and the survival periods extended to over 120 or 71.4±36.1 days respectively, P ＜0.001.

Scar resection in upper lip, orbicularis oris muscle reconstruction, Z-plasty, V-Y plasty or double movable mucomuscular complex flaps for vermilion defects were applied to slight nasolabial deformities. In severe labionasal deformities, Forked flap was used at the upper lip to lengthen columella for patients who have enough upper lip tissue, while for those who have deficient upper lip tissue, the prolabium was advanced into columella for lengthening and an Abbé flap was adopted for upper lip reconstruction. Results Since 2000, we have treated 23 patients of secondary deformities of bilateral cleft lip.

The contents of N, P, K in leaves were examined by regular leaf analysis. The results showed that the N content was higher in leaf blade than in leafstalk. N content in leaf was gradually reduced along with the vine growth. N, F, K fertilized at 20 to 40 cm soil layers significantly increased N content in leaf. But N content in leafstalk was less affected by N fertilization depth and growing season. P content was higher in leafstalk than in leaf blade. Less change of P content was noticed in leaf along with vine growth. However, N, P, K fertilized at 40 to 60 cm soil layers significantly promoted P in both leaf blade and leafstalk. K content in leafstalk was much higher than in leaf Wade. No obvious influence was noticed by fertilizing depth. But K content in leafstalk was significantly increased due to applied K fertilizer in late growing season.

结果表明，酿酒葡萄叶片中氮含量远高于叶柄，叶片中氮素含量随着生育期的延长逐渐降低，而叶柄中氮含量随施肥深度增加和生育期延长而产生的变化很小，40cm的施肥深度能显著增加叶片中氮素含量；叶柄磷素平均含量高于叶片，全生育期叶片磷含量变化很小，而施肥60cm深度显著促进了叶片和叶柄中磷含量的提高；叶柄中钾含量远高于叶片，施肥深度对叶柄和叶片中钾含量未产生明显影响，但生育后期追施钾肥显著提高叶片钾含量；施肥深度达到40cm时酿酒葡萄的产量最高，而60cm的施肥深度产量显著下降。

The results showed that:(1) The characteristic frequency of IC neurons of house mouse was increased with increasing recording depth, and the masker intensity used was positive relevant to the IC neurons\' minimum threshold. When the minimum threshold was high, the masker intensity needed was loud, vice versa.(2) According to the masking rate at MT+10dB of IC neurons to frequency modulation and tone burst, the IC neurons were classified as three types: type I neurons ( 72/113, 63.7%), in which the masking effect of TB was better than frequency modulation ;type II neurons (32/113, 28.3%), in which the masking effects of the two maskers were same; type III neurons( 9/113, 8.0%), in which the masking effect of FM was better than TB.(3) Type I neurons, the minimum threshold of which was low, but the Q_(10) and DR values of which were large; in type III neurons, the minimum threshold was high, the Q_(10) and DR values were narrow; in type III neurons, the MT Q_(10) and DR values were in between.(4) Both FM and TB could make the MT of type I neurons shift upward distinctively, but the effect of TB was more significant than FM.(5) The Q_(10) values of type I neurons became narrower under the influence of TB, were unaffected under the influence of FM.

结果显示：(1)小鼠下丘神经元的特征频率随着记录深度的增加而增高，掩蔽声强度与神经元的最小阈值呈正相关，即对高最小阈值的神经元进行掩蔽时需要的掩蔽声强度高，对低最小阈值神经元进行掩蔽需要的掩蔽声强度低：(2)根据调频声(frequency modulation， FM)和短纯音(tone burst， TB)对下丘神经元阈上10dB处反应的掩蔽，将小鼠IC神经元分为三类：Ⅰ类神经元(72/113，63.7％)，短纯音的掩蔽效果比调频声更好；Ⅱ类神经元(32/113，28.3％)，两者对神经元声反应的掩蔽率相同；Ⅲ类神经元(9/113，8.0％)，调频声的掩蔽效果更好；(3)Ⅰ类神经元的最小阈值低、Q_(10)值和动态范围大，Ⅲ类神经元最小阈值高、Q_(10)值和动态范围小，Ⅱ类神经元的最小阈值、Q_(10)值和动态范围介于Ⅰ和Ⅲ类神经元之间；(4)短纯音和调频声都可以使Ⅰ类神经元声反应的最小阈值明显上移，但短纯音使神经元最小阈值的上移更显著：(5)短纯音使Ⅰ类神经元的Q_(10)值变小，调频声使神经元的Q_(10)值增大不显著，短纯音与调频声对神经元Q_(10)的影响差别显著；(6)短纯音与调频声都使神经元的动态范围减小，并且作用显著，但短纯音的效果更显著：(7)短纯音与调频声都使神经元反应的潜伏期延长，效果显著，但TB的延长作用更为显著；(8)随着探测声强度的升高，短纯音和调频声对Ⅰ类神经元声反应的掩蔽率都降低，但在各个探测声强度短纯音的掩蔽率都比调频声高。
