ABSTRACT
Objective To cross-cultural adapt and test the reliability and validity of Humanistic Relationship Experience Scale (HRES) made by Boscart. Methods Cross-culture Adaptation was carried out by following American Academy of Orthopaedic Surgeons Evidence Based Medicine Committee (AAOS). A convenience sampling was conducted among 180 patients with chronic disease, and then assessed the reliability and validity of HRES. The internal consistency coefficient and the test-retest were used to assess the reliability of HRES, and the content validity index (CVI) and construct validity were used to assess the validity of HRES. Results In order to understand the purpose and content of the scale easily, the Chinese version title of HRES was revised to"Nursing Humanistic Care Experience Scale-Noninfectious Chronic Disease Patients Version (NHCES-NCDP)" after soliciting experts′ advice. The CVI of the scale was 1;factor analysis got three factors, which could explain 67.897％of the total variance. A 0.965 Cronbachαof total scale was obtained, and for each dimension range was 0.876-0.948;the test-retest reliability was 0.710 for the overall scale. Conclusion NHCES-NCDP is reliable and valid, which can be used to assess the experience of nursing humanistic care for patients with chronic diseases, and to explore nurses′implementation of nursing humanistic care.
ABSTRACT
Glucose oxidase (GOD) is an important industrial enzyme with many potential applications. In order to increase the production and productivity of GOD by recombinant Pichia pastoris GS115, we investigated the feeding strategies of mixed carbon sources during induction phase, based on results of the optimization of initial cell and methanol concentration on GOD production. The optimal initial cell and methanol concentration were 100 g/L and 18 g/L. During induction phase, the mixed-carbon-sources strategies showed that glycerol, sorbitol or mannitol co-feeding with methanol could enhance GOD production. With mannitol co-feeding (20:1(W/W)), the maximum GOD production and maximum GOD productivity reached 711.3 U/mL and 4.60 U/(mL x h) after an induction period of 156 h. Compared to the control, the enhancements of GOD production and productivity were 66.3% and 67.9%, respectively. Meanwhile, we found an appropriate mannitol co-feeding strategy that would not inhibit the expression of promote. The activity of alcohol oxidase was 8.8 U/g, which was enhanced by 69.2% compared to the control (5.2 U/g). We can use the same optimization process to improve the production of other proteins from recombinant Pichia pastoris by changing the fermentation parameters.
