Results: Thirty-four of the 37 cases chronic sinusitis with adenoidal hypertrophy in children were obviously improved by ESS and plasma ablation, and 10 of the 19 cases were improved only by plasma ablation.

结果：按ESS疗效评定标准（1997，海口）：37例中有效34例，有效率91.9%，19例中有效10例，有效率52.6%，两者有统计学差异。

Secondly, the pulse discharge plasma with allylamine was discussed, and the modification results with two kinds of discharge models were compared. The results showed that discharge models had influences on the plasma treatment results, especially under lower pressure and higher temperature with pulse discharge. The nitrogen element content in the layer under the pulse discharge was obviously lower than that under the continuous discharge, but there was higher proportion NH〓 groups remaining in the layer under the pulse discharge. The sample surfaces obtained by pulse discharge also had good biocompatibility.

其次讨论了脉冲放电模式下丙烯胺单体的等离子体修饰，比较了两种放电模式对修饰结果的影响，研究结果显示，放电模式对表面修饰层的结果有一定的影响，其中脉冲放电对低压及高温两等离子体条件下的影响尤为明显；脉冲放电下所得到的修饰层中的氮元素含量明显低于连续放电模式下，而脉冲放电下有较高比例NH〓基团保留在修饰层中；脉冲放电所得到的表面修饰层同样有较好的生物相容性。

in order to improve the anticoagulation of biomedical stainless steel, we fabricated the plasma-polymerized allylamine films on the surface of the biomedical stainless steel by pulsed plasma polymerization technique, and then immobilized the molecules of bovine serum albumin on the polyallylamine films.

采用脉冲射频等离子体聚合技术，在医用不锈钢表面制备了等离子体聚烯丙胺薄膜，并进一步在聚合薄膜表面固定白蛋白分子。

The SEM-EDS showed that the content of surface elements was changed after treated with glutaraldehyde or albumin indicated that argon plasma only had surface cleaning effect and did not change surface composition and the allylamine deposition thickness was too thin to show the difference in SEM-EDS findings. The XPS results confirmed the argon plasma cleaning effect and revealed that the ratio and the binding energy of surface elements changed with different treatment procedures and were similar to what expected to coat on the titanium surface.

XPS更进一步证实，氩气电浆只有清洁钛金属表面的作用，并不会改变其表面化学组成；其余各组的钛、碳、氮、氧的比例及键结能量随著处理程序而改变，可知表面上有化学组成之改变，且随不同处理程序所得到表面元素之百分比及键结能量，与预期的表面披覆物元素百分比及键结能量相近。

The patient avoided eating food rich of protein for three days and fasting for 12 hours before the blood samples were obtained at 7:00-8:00 in the morning, and had laid on bed for 15 minutes at least, 2ml of the blood samples were taken from median antebrachial vein, put into the heparinized tubles, then centrifugating by 1500/minute for 10 minutes,obtained the plasma from the blood, the plasma sample were kept in -72℃ refrigerator, ELISA method was used to determine the homcysteine level.

患者在标本采集前3天避免食用高蛋白饮食，空腹12小时以上，清晨7：00－8：00采血，采血时平卧位，休息15分钟以上，采集肘正中静脉血2ml，置于肝素抗凝管，以1500转／分离心10分钟后，分离血浆，用酶联免疫吸附法测定各管的HCY含量。

Grew on the normal temperature, it was shown that the deposits of calcium antimonate being the indicator for Ca(superscript 2+) localization mainly concentrated within the vacuoles and intercellular spaces and there was also some Ca(superscript 2+) deposits in cell walls. But when Garyota urens L. was treated by the temperature of 2℃ for 48 h, the level of Ca(superscript 2+) increased in cytoplasm and plasma membrane, but decreased in vacuoles and intercellular spaces considerably. At the same time, the ultrastructure of chloroplasts suffered from chilling: the membrane of chloroplasts had been damaged, the layer of thylakoids was exiguous and unclear, the photosynthetic rate decreased evidently. And when Garyota urens L. was treated by the temperature of 2℃ for 120 h, the deposits of Ca(superscript 2+) mainly concentrated within the cytoplasm, nucleus and plasma membrane and there was also some Ca(superscript 2+) deposits in vacuoles, and the ultrastructure of some cells was simultaneously damaged severely: Chloroplasts structure, vacuole membrane and nuclear membrane had been damaged fully, the structure within the cell had become unclear, and the cell only have respiration.

研究结果表明，未经低温处理的董棕幼苗叶肉细胞，焦锑酸钙沉淀颗粒大量出现在液泡和细胞间隙中，细胞壁中也可见少量沉淀，而细胞基质中则看不到焦锑酸钙沉淀；经2℃ 48 h低温处理后，细胞基质和细胞膜上焦锑酸钙沉淀增加，而液泡和细胞间隙中的焦锑酸钙沉淀则显著减少，并且超微结构已初步显示出寒害的特徵，叶绿体外膜部分破损，类囊体片层稀疏且排列不规则，光合速率明显下降等；经2℃ 120 h低温处理后，细胞间隙内的焦锑酸钙沉淀极少，有的也紧贴在细胞外壁上，而细胞基质和细胞膜上则分布有非常多的焦锑酸钙沉淀，在核基质和液泡中也可见到少量的焦锑酸钙沉淀，并且超微结构遭到了显著破坏，叶绿体结构完全被破坏，核膜与液泡膜严重破损，内部结构模糊，细胞只表现为呼吸作用，不进行光合作用。

It is the first time that these phenomena were observed: Two nuclei are surrounded by plasma and locate at the central of the female gametophyte and the others nuclei are positioned at the fringe of the female gametophyte; Before the pollen tube enters the female gametophyte. the nuclei in chalazal end begin splitting of plasma and form multinuclear cell.4.
