ABSTRACT
Enzyme is an efficient and green biocatalyst, and widely used in many areas. Immobilized enzyme is superior to its free form in a variety of properties. Enzyme immobilization studies started in the 1970s in China. Till now, immobilized enzymes are widely applied in the fields of food, medical, energy, environmental management, among others. However, there are still some defects such as no universal method and the high cost. Therefore, based on the relatively mature traditional immobilization technologies, efforts have been made to innovate immobilization technologies. As a result, many new immobilization technologies focusing on new carriers and methods are continuously generated. Coupling with more than ten years' study on enzyme immobilization, we present here recent development and application of new immobilization technologies, as well as suggestions to future development of immobilization technology.
ABSTRACT
Objective To explore the effect of the clinical case oriented management model on nurses comprehensive ability, psychological and critical mind. Methods In 2014 on the implementation ofroutine clinical case management modelas the control group, collected 97 cases of clinical cases. In 2015 on the implementation ofthe clinical case oriented management modelas the observation group, collected 110 cases of clinical cases. Compared two methods of management to improve the nurse management theoretical knowledge, clinical practice ability and deal with the size of the case skills help. When/after clinical special case found the influence for nurses, including psychology, work in the nursing work will, enthusiasm, independent ability to deal with related cases and the nurse critical thinking ability, etc. Results The proportion of the nurses thought that it was helpful to improve the management of theoretical knowledge, clinical practice ability and deal with the size of the case skills and the case analysis of satisfaction were 98.79%(244/247), 99.19%(245/247), 98.79%(244/247), 99.60%(246/247) in the observation group, and 88.57%(217/245), 87.35%(214/245), 87.76%(215/245), 90.61%(222/245) in the control group. The differences were statistically significant (χ2=21.390-27.571, P < 0.01). The proportion of the nurse considered that special case on the psychological effects of nursing work, engaged in the willingness and enthusiasm were the main factor were 15.79%(39/247), 13.77%(34/247), 11.34%(28/247) in the observation group, and 31.84%(78/245), 31.02%(76/245), 30.61%(75/245) in the control group. The differences were statistically significant (χ2=17.475, 21.097, 27.611, P < 0.01). After special case, the percentage of nurses to independently handle the case, help others, loss rates were 97.57%(241/247), 2.02% (5/247), 0.40% (1/247) in the observation group, and 85.71% (210/245), 12.24% (30/245), 2.04% (5/245) in the control group. The proportion of nurses to independently handle the case in the observation group was higher than that in the control group, but the ratio of nurses to help others, loss rates in the observation group were lower than those in the control group, the differences were statistically significant (χ2=22.647, P<0.01).Critical thinking score, the observation group of nurses in the search for truth, open mind, analytical ability, system organization, judging thinking self-confidence, curiosity, cognitive maturity, such as total score were respectively (43.24±4.01), (43.03±4.12), (47.66±4.23), (44.21± 3.92), (44.00 ± 4.97), (52.13 ± 4.44), (48.23 ± 4.85), (319 ± 14.57) points. The control group nurses were respectively (39.00±3.56), (38.90±3.28), (43.65±2.47), (40.55±1.99), (39.00±3.40), (47.87±4.01), (41.89± 5.11), (292.23 ± 6.02) points. The differences were statistically significant(t =12.15-24.19, P < 0.01). Conclusions The clinical case oriented management model can improve nurses comprehensive ability, reduce the adverse impact of the special case for nurses, improve the clinical nurses' critical thinking ability, to ensure patient safety.
