ABSTRACT
Recently, considerable attention has been paid to European eggs that were found to contain the poisonous insecticide fipronil. Excessive consumption of fipronil can harm the human body, in particular, the liver, thyroid, nervous system and kidneys. As a consequence, there is an urgent need to develop a method to detect fipronil. In this work, a lanthanide coordination polymer [Eu(SIP)(H2O)4]n (1) (NaH2SIP = 5-sulfoisophthalic acid monosodium salt) was synthesized and characterized by single-crystal X-ray crystallography, elemental analysis, infrared spectrum and powder X-ray diffractions. The X-ray studies show that 1 is a two-dimensional layered structure, which is constructed of fused {[Eu(H2O)4]3(SIP)3} pseudo-hexagonal grids. The luminescence properties of 1 exhibit effective recognition for fipronil in methanol solution. Furthermore, a wide linear range (10-6-10-4 M), a low detection limit of 0.8 µM, high selectivity and excellent recyclability, reveal that 1 can potentially act as a luminescence-based sensor for quantitative and highly sensitive detection of fipronil. To the best of our knowledge, it is the first time that a metal-organic coordination polymer, as a fluorescent-based probe, has been used for the detection of fipronil. Moreover, fluorescent-based test papers of 1 have also been prepared, which can be regarded as a simple and practical method for detecting fipronil.
ABSTRACT
BACKGROUND: With the great development of liver transplantation in China, long survival and quality of life after liver transplantation have been matters of growing interest. This study was designed to investigate the impact of personality and coping skills on the quality of life after liver transplantation. METHODS: Fifty-five outpatients who had been followed up after liver transplantation at our center were assessed by general quality of life inventory (GQOLI-74), a medical coping modes questionnaire (MCMQ), an eysenck personality questionnaire (EPQ), and a general condition questionnaire(GCQ). RESULTS: The score for material well-being was the lowest(63.22+/-12.67) and for psychological well-being the highest(73.43+/-12.60) in 4 dimensions of the GQOLI in post transplantation patients. Their main coping method was confrontation (21.40+/-3.70). The main characteristics of their personality were extraversation (E score 12.96+/-4.13) and neuroticism (N score 8.20+/-4.90). The total score of the GQOLI was positively correlated with confrontation and E score, and it was negatively correlated with acceptance and N score. The physical well-being positively associated with the E score. The psychological well-being was positively correlated with confrontation and L score, and was negatively correlated with acceptance, P and N score. Social well-being was positively correlated with confrontation and E score, and was negatively correlated with acceptance and N score. Material well-being was not correlated with coping methods and personality. CONCLUSION: The quality of life in post liver transplantation patients is associated with their psychological characteristics.
