Objective: To investigate the urinary metabolic spectrum and pathways in very low birth weight (VLBW) premature infants. Method: A prospective case-control study was conducted to collect and compare the data of VLBW premature infants and full term infants from the Sixth Affiliated Hospital of Sun Yet-Sen University in 2014. Within 24 hours after birth, urine specimens in each group were collected. Metabolites of urine samples including amino acid, fatty acid and organic acid were detected using the urease pre-processing and gas chromatography mass spectrometry (GC-MS) technology. Using the orthogonal partial least squares discriminant analysis (OPLS-DA), the biomarkers and differences between the two groups were found. The online metabolic pathway website was explored and multivariable analysis was conducted to investigate the valuable pathways and biomarkers related to the prematurity. Result: A total of 20 VLBW premature infants were enrolled, among whom 11 were male, 9 were female; and 20 full term infants were enrolled, among whom 9 were male, 11 were female. The urinary metabolites were established and compared between the VLBW premature and term infants. The investigation showed that the following nine pathways were enriched: amino-acyl-tRNA biosynthesis(P=0.000), lysine degradation(P=0.007), fatty acid biosynthesis(P=0.008), pyrimidine metabolism(P=0.014), pantothenate and CoA biosynthesis(P=0.022), valine, leucine and isoleucine biosynthesis(P=0.022), lysine biosynthesis(P=0.031), glycerolipid metabolism(P=0.046), and valine, leucine and isoleucine degradation(P=0.031). Almost all the metabolites decreased except for the glyceric acid exhibiting a higher content in the VLBW premature infant. 12 potential biomarkers were explored with the most significant covariance and correlation, within which stearic acid, palmiticacid, myristic acid, β-amino-isobutyric acid, and uric acid were lower, while myo-inositol, mannitol, glycine, glucose1, glucose2, glyceric acid and N-acetyl-tyrosine were higher in the VLBW premature group compared with the control group. Conclusion There is a significant difference between the VLBW premature infants and full-term infants in the metabolic state and pathways. The urease pre-processing and GC-MS technology followed by the OPLS-DA and multivariable analysis to investigate VLBW premature infants′ urinary metabolites is a valuable method to evaluate the patients′ metabolism.

Objective To evaluate the application effect of concept map guided nursing in the high quality nursing of diabetic patients. Methods A total of 119 hospitalized diabetic patients from March 2016 to December 2016 were selected using convenient sampling and randomly divided into the control group (n=59) and observation group (n=58). Conventional nursing ward round were conducted in the control group, and the concept map nursing round were used in the observation group. Patients' satisfaction was evaluated using satisfaction questionnaire. The Chinese critical thinking disposition inventory (CTDI-CV) was used to evaluate the ability of nurses' critical thinking. Results Scores of all dimensions of nursing satisfaction and the total score in the observation group were significantly higher than those in the control group (P< 0.05). After the implementation of concept map nursing round, scores of critical thinking in nurses truth seeking, analysis ability, open-mind, systematic ability, self-confidence of critical thinking and curiosity and the total score were improved when compared to those of nurses before the implementation; the differences were statistically significant (P<0.05). Conclusions Clinical application of concept map, which provides human-based high quality nursing service for patients, can optimize the nursing quality and improve the critical thinking ability and quality of nurses.
