Methods Treatment and nursing were performed on 25 patients with pulmonary edema related to uremia.When nursing patients with pulmonary edema related to uremia,besides general nursing measures,the following aspects should be included:（1）specially observing the blood pressure,respiration and arterial blood oxygen saturation and urine volume of patients;（2）controlling the blood pressure of patients effectively;（3）dialysing or ultrafiltrating in proper manner and at proper time,meanwhile nursing carefully during dialysis;（4）ameliorating the general nutritional status of patients to prevent infection of the lungs;（5）keeping firmly in mind the care program:post????oxygen????drugs of vasodilatation????hemodialysis;（6）controlling water drinking.

共治护25例肺水肿患者，对尿毒症性肺水肿除采取常规护理措施外，应做到以下几点特殊护理：（1）密切观察血压、呼吸、血氧饱和度、近期尿量变化；（2）有效控制血压；（3）采取不同的透析方式适时适量透析超滤并加强透析中的护理；（4）改善全身营养状况、纠正贫血、预防肺部感染；（5）牢记护理程序体位―吸氧―血管扩张药―血液透析；（6）严格控制入量。

The oxygen atom can strengthen the wafers, and prevent plastic deformation during high temperature process. Furthermore, the oxygen precipitates and oxygen-induced defects can provide gettering sites so as to get a high-quality surface denuded zone.

氧可以增大硅片的机械强度，抑止硅片在高温时的塑性变形，氧沉淀以及随后诱生的二次缺陷可以有效地吸除工艺过程中引入的金属杂质玷污，从而获得高质量的表面洁净区。

The scavenging effect of polyphenols extracted from grape seeds such as monomers, dimers and trimers on superoxide and hydroxyl radicals is studied with the ESR spin trapping method. The results are comparable with those obtained from chemiluminescence method. It has been proved that polyphenols extracted from grape seeds have a strong scavenging effect on Oxygen free radicals. Probably this is the reason why drinking some grape wine every day is good for one's health.

用ESR自旋捕集技术研究了从葡萄籽分离的单体、二聚体和三聚体等多酚类物质对羟基自由基和超氧阴离子的精除作用，并与化学发光法的测定结果进行了比较，得到了较一致的结果，证明葡萄籽中多酚类物质对氧自由基的确有较好的清除作用，这很可能是喝少量葡萄酒有利于身体健康的原因。
