The extraction and stability of the pigments in Tussilago farfara L. were studied. The experimental results showed that the pigments could be solved in acetone. The stability of the pigments is good when pH is within 3~9; the oxidizing agents, reducing agents and common food additives have little influence on its stability; it is react too much with Fe(superscript 3+) ion, and Na(superscript +) ion showed a certain increment effect on the color; the heat performance of the pigments is good when under 60℃.

研究了款冬花色素的热稳定性、氧化还原稳定性和pH值稳定性，并对常用的几种食品添加剂对款冬花色素的稳定性进行了探讨，结果表明：款冬花色素易溶于丙酮，属于脂溶性色素；在pH＝3～9时，款冬花色素的稳定性较好；氧化还原剂及食品添加剂对其稳定性影响不大，Fe(上标 3+)金属离子对其影响显著，Na有增色作用；水浴温度在60℃以下色素的热稳定性较好。

First,"Dreams of the Red Chamber" is a complete overthrow of the Chinese traditional twenty-four histories, and has opened up for us, in a gigantically breading way, the third pedigree of human history with the male and female love as the core and different from the pedigree with the dual division between the good and the bad. Next, along with the affirmation of the third pedigree of human beings,"Dreams of the Red Chamber" enable the female sex acting as the "second sex" for long to come again onto the stage in the human history, thus unprecedentedly disclosing the incomparably grave historic tragedy of the female sex in reality. Finally, more importantly,"Dreams of the Red Chamber" not only consider the ruling of the current discourse as the deepest cause of the female tragedy but also make a restoration with the meaning of the life generation science for the human discourse so as to make the initial word "discourse of love" more original than the discourse of the knowledge nature and bring the following of "God of lover", the new salvation way, into the agenda.

首先，《红楼梦》是对中国传统二十四史的彻底颠覆，并大破大立地为我们开辟出有别于善恶二分谱系的一种以男女情爱为核心的人类历史第三谱系；其次，随着对这一人类第三谱系肯定，《红楼梦》使长期作为&第二性&的女性在人类历史中重新登场，并前所未有地揭露了现实中女性无比深重的历史悲剧；最终，更重要的是，《红楼梦》不仅把现行话语的统治视为女性悲剧的最为深刻原因，而且同时对人类话语进行了一种生命发生学意义的还原，而使一种有别于知识性话语的更为始源的&情的话语&这一泰初之言得以彰显，把对&情的上帝&的昄依这一新的救赎之途提到人类文化的议事日程。

To study genetic mutations of methylenetetrahydrofolate reductase C677T and cystathioinine-β-synthase T833C related to homocysteine metabolism in patients with ischemic stroke, the MTHFR gene C677T gene mutation and the CBS T833C gene mutation were detected by PCR-RFLP or ARMS method in 74 patients with ischemic stroke and 83 normal people for control. Results showed that the frequencies of MTHFR genet homogenetic type(2.7%), heterogenetic type(51.4%) and T allele(28.4%) in ischemic group were higher than those in control group(1.2%, 39.8% and 21.1%, respectively).

MDA content, cell division , he activities of NR, CAT, POD and SOD of Pistia sagittifolia and Myriophyllum Spicatum with heavy metal,s ion concentration to appear a trend of ascending firstly and desending secondly . This trend explains that Pistia sagittifolia and Myriophyllum Spicatum on the Toxic Effects have similarities under handing the single Pb2+ and Hg2+. As the range of the concentration which each index is arriving at the maximum is different, this also indicates that there are some differences of the Toxic Effects between Pistia sagittifolia and Myriophyllum Spicatum under handing the single Pb2+ and Hg2
