Among them, 20 patients were candidates of valve replacement and 18 PDA and pericarditis had their blood samples taken before operation,and 1,2,24 and 48 hours after closure of thorax for measurement of concentrations of CK、CK-MB and TnT,together with ECG recording. Results Of the 60 patients, concentrations of cTnT before operation were normal; 2 hours after aortic unclamping, the correlation coefficient between cTnT and aortic clamping was r = 0.873( P＜0.01), the regression analysis showed Y = 0. 019X-0. 026. Of the 20 patients, ECG showed the myocardium was ischemic; CK、CK-MB and cTnT all rose significantly, reaching the peak after closure of thorax. Of the 18 patients, the ECG and cTnT before operation and after closure of thorax were normal; except 2 patients with pericarditis.

结果 60例瓣膜手术患者术前cTnT均在正常值范围内，主动脉开放后2 h时，阻断时间和cTnT的相关系数为r=0.875(P＜0.01)，回归方程为Y=0.019X-0.026；其中20例瓣膜手术患者心脏经过阻断后，心电图有缺血性改变，周围血液中的CK、CK-MB和cTnT均有明显升高，分别在关胸后2 h达到高峰，数值分别为术前的12.6、9.2和257倍；18例行动脉导管结扎和心包剥脱术的患者术前和关胸后的心电图和血液中的cTnT均正常，CK和CK-MB除2例心包炎患者关胸后出现明显变化外，余均未见改变。

On the basis of the peak absorption values of the visible spectra of MB, the dimerization constants and the molar absorption coefficients of the monomer and the dimer of MB were calculated.

根据MB特征峰处的吸收光谱值，计算了MB的二聚平衡常数和相应单体、二聚体的摩尔消光系数。并用稳态荧光法和无外加探针的循环伏安法进一步论证了计算结果。

Results:The spective sensitivity value of cTnI,CK-MB and Mb were 93.3%,86.7% and 78.3%;the spective specificity value were 100%,100% and 88.0%;the sensitivity and specificity value of both cTnI and Mb were 96.7% and 88.0%;the sensitivity and specificity value of all cTnI,Mb and CK-MB were 98.3% and 88.0%;the positive and negative expectative value were 95.2% and 88.0%.

结果：患者入院后24 h内cTnI、CK-MB和Mb对AMI的敏感性分别为93.3%，86.7%和78.3%，特异性分别为100%，100%和88.0%；同时检测cTnI和Mb时AMI的敏感性为96.7%，特异性为88.0%；同时检测cTnI、Mb和CK-MB时AMI的敏感性为98.3%，特异性为88.0%，阳性预期值为95.2%，阴性预期值为88.0%。

The developing principle of MB gypsum fine foamer which takes compound honey-locust abietic acid anionic surfactant as principal composition,is analyzed in theory.

从理论上分析了以复合型皂角松香酸类阴离子表面活性剂为主要成分的MB石膏微发泡剂的研制原理，详细研究了MB微发泡剂在石膏料浆中的起泡条件、起泡性能及其对硬化后的建筑石膏物理力学性能的影响，MB微发泡剂与现有发泡剂的性能比较，MB微发泡剂在纸面石膏板中的应

In our study, we found menadione has anticancer potential on human breast adenocarcinoma MDA MB 231 by weather cell cycle arrest, anti proliferation, or apoptosis. Low concentration of menadione (5.8μM) significant inhibited growth curve on breast cancer cells (MDA MB 231) but not breast cells (MCF 10A) by performing MTT and trypan blue cell counting. RT-PCR and western blotting showed menadione increase p21 gene and protein expressions but decrease cyclin E and CDK2 protein expression resulting in cell cycle G0/G1 arrest by flow cytometry.

MTT及生长曲线的实验，发现menadione在低浓度且长时间作用情况下，对在於人类乳腺上皮细胞癌(MDA-MB 231)是有明显的抑制作用，而在正常乳腺细胞(MCF-10A)则没有影响，在分子转录上及蛋白质表现方面也发现低浓度menadione处理24时能使MDA-MB 231诱发p21基因及蛋白表现量增加及cyclin E、CDK2抑制，再经由流式细胞仪分析也发现低浓度 menadione 处理24小时能使MDA-MB 231细胞周期GO/G1比例上升，造成细胞周期停滞，进而抑制细胞生长。

This is caused by the intercalation of MB to DNA bases which restricts the rotational motion of MB.

溴化乙锭的存在使MB-DNA体系的荧光强度增强，这是由于溴化乙锭与MB竞争结合DNA而使MB与DNA的结合反应向左移动，溶液中游离MB浓度增加了的缘故。

The CPF/ZnO nanomaterial, obtained by treating the precursor PF/ZnO at 460 ℃ for 40 min, could fully decolorize and degrade dye MB in 10 min under the natural light compared with 10% degradation of MB on ZnO only under the same reaction condition. The decolorizing efficiency will be still above 80% after 3 cycles.

如在460 ℃下处理40 min所得的纳米复合材料，在自然光条件下，10 min即可使MB溶液完全脱色，而在相同条件下，纯纳米ZnO仅能使MB的脱色率为10%左右；该催化材料重复使用3次仍可使MB溶液的脱色率保持在80%以上。

Result Among 384 MB patients, 4 had relapsed in Xingyi City. The mean relapse rate was 0.15/100 person-years. In Puan County, 1 out of 297 MB patients had relapse. The mean relapse rate was 0.05/100 py. A total of 5 cases of relapse in these counties, and these figures were not included in the man-year relapse rate study.
