Methods 120 patients with chronic heart failure were randomly divided into two groups. Patients in both groups were treated with digitalis, diuretic and angiotensin-converting enzyme inhibitor and patients in treatment group received additional amlodipine.

采用随机对照的方法，将120例慢性心功能不全患者随机分为治疗组和对照组，对照组以洋地黄、利尿剂及血管紧张素转换酶抑制剂等药物治疗，治疗组在对照组治疗基础上加用氨氯地平片(5~10)mg/d。

Those indices such as AOPPs, protein thiol groups and dityrosine were used as biomarkers of protein injury.

对照组内不加任何尿毒素。37℃分别温育0.5 h和24 h后，分别测定各组的AOPPs、蛋白巯基及二酪氨酸浓度。

The result indicated that the reacting mixture containing dioxane 11.3mL/g HDCA which had been added ethyl chloroformate drop wise should be keep at 10℃ for 30min, then, rising to 15℃ for another 20min in the step of forming mixed anhydride ,and 1.5mol/L NaOH was used to dissolve taurine before aminolysis, and crude product was recrystalled by acetone in purifying process.

结果表明，形成混酐时，二氧六环用量为11.3ml/g HDCA，滴加氯甲酸乙酯后先在10℃反应30min，再在15℃下反应20min；用1.5mol/L的NaOH水溶液溶解牛磺酸后再进行氨解；粗产品用丙酮重结晶。

A salt or ester of butyric acid .

加有一个碘原子的酪氨酸。

Synthesis process of 2,6-dichloro-3-methylaniline was investigated 3-methylaniline was first N-acetylated with acetic anhydride,then treated with chlorosulphonic acid and ammonia yielding the 2-methyl-4--benzenesulfonic amide,which wasin turn deacetylated,chlorinated and hydrolyzed to the title compound.Hydrochloric acid was used instead of sodium hydroxide in deacetylation and sodium chlorate instead of hydrogen peroxide as oxidant in chlorination.

合成工艺2，6-二氯-3-甲基苯胺调查3-甲基首次N-乙酰与醋酸酐，然后与氯磺酸和氨产量 2-甲基-4--苯磺酰胺基，而擅转乙酰，氯化和水解的标题compound.hydrochloric酸代替氢氧化钠乙酰氯酸钠代替双氧水为氧化剂，加氯。

A salt of iodic acid .

加有三个碘原子的甲腺氨酸。

A preparation method of the visible-light photocatalyst Bi2WO6 nano-powder is characterized by comprising the steps as follows:(1) the selection of raw materials;(2) bismuth nitrate Bi(NO33 question mark 5H2O is added into a citric acid solution to obtain the citric acid solution containing white sediment;(3) EDTA is added into ammonia water which is then added dropwise with the citric acid solution containing the Bi(NO3)3 question mark 5H2O so to obtain a solution of bismuth;(4) the solution of bismuth is added with (NH4)6W7O24 question mark 6H2O solution to form a precursor solution which is then stirred, dried, coked, cooled and ground to obtain decarburized powder;(5) the decarburized powder is roasted for 2h to 4h under 450 DEG C to 550 DEG C to obtain the visible-light photocatalyst Bi2WO6 nano-powder.

可见光催化剂Bi 2 WO 6 纳米粉体的制备方法，其特征在于它包括如下步骤：1原料的选取；2将Bi(NO 3 ) 3 5H 2 O加到柠檬酸溶液中，得到含有白色沉淀的柠檬酸溶液；3将乙二胺四乙酸加到氨水中，并缓慢滴加入含有Bi(NO 3 ) 3 5H 2 O的柠檬酸溶液中，得铋的溶液；4将(NH 4 ) 6 W 7 O 24 6H 2 O溶液加入上述铋的溶液中，组成前驱液；搅拌，干燥，焦化，冷却后，研磨，得去碳的粉体；5将去碳的粉体在450～550℃下焙烧2～4h后，得到可见光催化剂Bi 2 WO 6 纳米粉体。
