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).

为研究同型半胱氨酸代谢相关酶亚甲基四氢叶酸还原酶基因C677T和胱硫醚-β合成酶基因T833C位点碱基突变与缺血性脑卒中的关系，对74例缺血性脑卒中患者和83例健康对照者，采用聚合酶链反应-限制性片段长度多态性技术检测MTHFR基因C677T基因型，用扩增阻滞突变体系法检测CBS基因T833C突变。

It was found that manganese porphyrins linked with stable nitroxyl radials could oxidize sulfides using NaOCl as the oxidant to give the corresponding sulfoxides in good to excellent yields (80-97%) with high chemoselectivity and diasteroselectivity (dr≥7:1 for glycosyl sulfoxides).

发现连有稳定氮氧自由基的卟啉锰络合物对NaOCl选择性氧化各种硫醚底物有较好的催化效果，获得了高的产率(80％～97％)、化学选择性和非对映选择性(糖基亚砜非对映异构体的比例大于7：1)。

MPH plastic magnetic pump complies with JB/T7742-1995Standard for Small Magnetic Transmission Centrifugal Pump. Its flow-through parts adopt PPS with corrosion resistance to most acid, alkali and salt (except oxidable acid like strong sul-furic acid, nitric acid and aqua regia). Its performance is close to the chemical performance of F4, which can resist to most organic solvents under 100℃, especially to the mixture of gas and carbinol. Thus it is an ideal pump for acid and alkali industries.

MPH型塑料磁力泵符合JB/T 7742-1995《小型磁力传动离心泵》标准，过流部件采用聚苯硫醚，不受大多数酸、碱、盐的侵蚀(除氧化性酸如浓硫酸、硝酸和王水等)，其性能接近于聚四氟乙烯的化学性能，在100℃以下能耐大多数有机溶剂，特别能耐汽油和甲醇的混和液，是酸碱工业中的理想用泵。

In the cardiovascular system, the endogenous NO, CO, and H2S form three specific and relevant pathways with their corresponding enzymes including nitric oxide syntheses, the home oxygenize and cystathionine-r-lyric enzyme, whose affect can relieve the atherosclerosis.

血管系统中内源性气体信号分子NO、CO、H2S作为一种独特的血管活性物质，分别与其相应的合成酶一氧化氮合酶、血红素加氧酶和胱硫醚－r-裂解酶形成独立而又相互关联的体内重要抗氧化系统，可以减少动脉粥样硬化的严重度。

Pyridoxine, pyridoxal , pyridoxamine as well as their phosphated forms are structural analogues in which pyridoxal-5"-phosphate and pyridoxamine-5"- phosphate are the biological active forms in vivo which act as the cofactors of aminotransferases, amino acid decarboxylases, cysteine desufbrase and cystathionine , etc by constant transconversions. Recently, it was discovered that B6 played a novel role in tumor growth suppression.

它包括三种结构十分近似的化合物：吡哆醇(Pyidoxine，PN)、吡哆醛(Pyridoxal，PL)和吡哆胺(Pyridoxamine，PM)，分别以磷酸化的形式发挥作用，其中吡哆醛-5'-磷酸(Pyridoxal-5'-phosphate，PLP)为B_6在体内的活性形式，通过与磷酸吡哆胺(Pyidoxamine-5-phosphate，PMP)的互变，作为多种酶(氨基转移酶、氨基酸脱羧酶、半胱氨酸脱硫酶、胱硫醚酶等)的辅酶而发挥传递基团的作用。
