考察了水中苦味酸在弱碱性离子交换树脂D301R上的吸附与解吸。研究了吸附热力学、动力学特性及吸附机理。结果表明,树脂在pH=2.7~10.2时,吸附能力最好。等温平衡吸附遵循Freundlich模型。吸附过程为吸热、熵增的自发过程。吸附动力学符合Lagergren准二级速率方程,颗粒内扩散为吸附速率的主要控制步骤,吸附速率常数为7.23×10-5~1.20×10-4g/(mg.min),吸附活化能为19.4 kJ/mol。树脂上吸附的苦味酸可用HNO3+丙酮混合液定量洗脱,洗脱率达99%。静态吸附和脱附的比较结果证实了吸附过程中存在不可逆化学吸附。树脂对苦味酸的吸附主要是通过静电吸附、酸碱络合吸附、氢键吸附等协同作用来完成的。 相似文献

目的 探讨股前外侧肌皮瓣修复小腿截肢残端软组织缺损,保留小腿长度或膝关节以利于假肢装配.方法 2013年4月-2016年11月,应用股前外侧肌皮瓣对小腿截肢残端软组织缺损进行修复4例,其中游离肌皮瓣3例,带蒂肌皮瓣1例.患者均为男性,截肢肌创面位于小腿近端,年龄8~48岁,平均20岁,创面面积7.0 cm×6.0 cm^25.0 cm×10.0 cm.一期清创后二期修复,肌皮瓣面积13.0 cm×10.0 cm^28.0 cm×12.0 cm,保留胫骨长度5.2~9.4 cm.结果 肌皮瓣全部成活,1例肌皮瓣边缘出现浅表感染经换药处理后愈合,供区无并发症.所有患者随访12~37(平均19)个月,末次随访时皮瓣血运好、质地柔软、耐磨.皮瓣感觉恢复程度:S22例, S31例,S3+1例. 6 min步行测试:Ⅳ级2例,Ⅲ级2例;Stanmore运动分级:V级2例,Ⅳ级2例.结论 股前外侧肌皮瓣是修复小腿截肢残端软组织缺损的理想皮瓣. 相似文献

臂丛损伤患者的生存质量调查分析 总被引:1,自引:0,他引:1
Objective To investigate the quality of life on brachial plexus injury patients in crosssectional study method and acquire related data. To analysis the effect factors and try to study on the methods which help to improve the quality of life of these patients. To our knowledge, this is the first study that measures quality of life of the brachial plexus injury patients in China. Methods Research participants completed the Chinese version of the World Health Organization Quality of Life Assessment-Bref (WHOQOL-BREF) and the 5-items version of International Index of Erectile Dysfunction Questionnaire (IIEF-5) for male.Data were typed into computer and analyzed with SPSS version 13.0. Correlations between domain scores and hospital stay, age, and family monthly income variables were analyzed with Spearman non-parameter correlation analysis. Results Fifty-one valid questionnaires were retrieved. The average score of these patients in physical, psychological, environment domains were 11.47 ± 2.36, 12.37 ± 2.28 and 11.62 ± 2.22, respectively. They were significantly lower than the norm groups in national studies which were 15.8 ± 2.9, 14.3 ±2.5 and 13.2 ± 2.4 (P < 0.01 ). The average score of IIEF-5 was ( 17.83 ± 4.65), significantly lower than the normal score of 22 (P < 0.01 ). Significant correlation was found among physical domain and age(P < 0.05),family monthly income (P < 0.05) and IIEF-5 score(P < 0.01). Psychological domain also has significant correlation with IIEF-5 score (P < 0.05) and so does environment domain with family monthly income (P <0.05). Conclusion Brachial plexus injury patients showed a reduction in quality of life scores. Even though the physical aspect was the most affected, there is evidence that the psychological, environmental domains and erectile function remained far from the ideal conditions expected for the general population. The effect factors are complex and there still remain much work to do. 相似文献

硝基呋喃类和硝基咪唑类药物的研究进展 总被引:14,自引:0,他引:14
目前,细菌感染仍是危害人类健康的主要疾病,全身及局部应用抗生素是杀灭体内致病菌的主要方式.硝基呋喃类及硝基咪唑类药物因杀菌能力强、抗菌谱广、不易产生耐药性、价格低廉、疗效好,在临床得到广泛应用.硝基呋喃类主要用于治疗泌尿系感染、肠道细菌感染、皮肤创伤感染以及作为食品添加剂预防家禽肠道传染病.硝基咪唑类对厌氧菌及原虫有独特的杀灭作用,与其他抗生素联合应用于临床的各个领域.但硝基杂环类化合物具有细胞诱变性、动物致癌毒性,已引起了临床的高度重视.本文将硝基呋喃类及硝基咪唑类常用药物的临床应用及副作用综述如下. 相似文献
