A gas chromatographic method has been developed for determining glycerin concentrations of both therapeutic and physiological levels in serum. The linear relationship was obtained in the range of 1.6-800 ug/ml and the coefficient variations determined within a day and between days were 2.2% and 2.4% respectively. Recoveries of glycerol from serum were about 87%.

Objective To explore the application value of sensitive index of nursing quality in nursing management of patients with cancer pain.Methods One hundred and eight patients with cancer pain in the First Affiliated Hospital of Xinxiang Medical University from February 2014 to March 2015 were selected as the control group;one hundred and eight patients with cancer pain in the First Affiliated Hospital of Xinxiang Medical University from April 2015 to June 2016 were selected as the study group.The traditional cancer pain nursing quality evaluation criterion was taken in the control group,and the improved cancer pain nursing quality evaluation criterion was taken in the study group to evaluate the nursing quality.The accuracy of pain assessment,awareness rate of cancer pain knowledge,degree of satisfaction to the nursing work were compared between the two groups.Results The accuracy of pain assessment of patients in the study group (90.7％,98/108)was significandy higher than that in the control group (45.4％,49/108) (x2 =51.16,P ＜ 0.05);the awareness rate of cancer pain knowledge of patients (98.1％,106/108) in the study group was significantly higher than that in the control group (72.2％,78/108) (x2 =28.83,P ＜ 0.05);the satisfaction rate of the patients in the study group (100.0％,108/108) was significantly higher than that in the control group (85.2％,92/108) (x2 =17.38,P ＜ 0.05).Conclusion The overall quality of cancer pain care can be improved by strengthening the quality evaluation of the pain assessment accuracy and the awareness rate of cancer pain knowledge in patients with cancer pain.

Objective:To study the effects of early intervention on physical and neurological development of premature infants.Methods:One hundred and fifty-two premature infants born in Pan′an County Maternal and Child Health Family Planning Service Center from January 2017 to June 2018 were randomly selected. According to parents′ wishes, 75 cases received regular systematic health care and parenting guidance(control group), and 77 cases received targeted intervention guidance and individualized training on the basis of the control group(intervention group). The results of mental development index (MDI) and psychomotor Development index(PDI) were evaluated at 6 and 12 months respectively.Results:Six and 12 months after treatment, the MDI scores of the intervention group were significant higher than those of the control group [(94.2 ± 5.2) scores vs. (85.3 ± 6.1) scores, (104.9 ± 3.9) scores vs. (91.7 ± 5.7) scores], the PDI scores of the intervention group were also significant higher than those of control group [93.7 ± 4.3) scores vs. (81.7 ± 5.5) scores, (96.9 ± 3.8) scores vs. (83.9 ± 4.6) scores], and there were statistical differences ( P<0.05). Results:Early comprehensive intervention for premature infants has a good effect on their intelligence and motor ability development, which is worthy of clinical application.
