Objective To investigate the therapeutic effects of two parenteral nutrition (PN)methods in preterm infants. Methods Forty-two preterm infants who could not tolerate full enteral feeding were randomly divided into two groups. Twenty-two cases of the experimental group started to receive amino acids (AA) by 1.0 g/(kg·d) within 24 h after birth. Then AA was increased by 1.0 g/(kg·d)each day to maximum of 3.0 g/(kg·d)The dose and add method of intralipid was given alike AA within 48 h. Complete PN was achieved 5 d after birth. Twenty cases of the control group started to receive AA by 0. 5 g/(kg·d) ,and then increased by 0. 5 g/(kg·d) each day to maximum of 3.0 g/(kg ·d). The dose and add method of intralipid was given alike AA after 72 h. Complete PN was achieved at 8 or 9 d after birth. The feeding results was observed,the blood biochemistry was monitored at 72 h and 10 d after birth,and the incidence of complication was recorded. Results In comparison with the control group, time returning to birth weight, the weight loss rate, PN time and time returning to full enteral feeding were shorter in the experimental group (P ＜0. 01). There were no significant differences in the blood glucose,total bilirubin, urea nitrogen,carbon dioxide combining power,total cholesterol and the incidence of complication between the two groups (P ＞ 0. 05). Conclusion Quantity sufficient and early parenteral nutrition can be tolerated by preterm infants within 24 h after birth.

As the change of medicine mode,measuring approaches of patient satisfaction have been widely focused on and become an important tool to improve the quality of medical service.This paper is aimed to analyze the latest development of patient satisfaction questionnaires including relevant content and methods by literature review.

Objective:To investigate the present situation of unintended pregnancy within two years postpartum and its influencing factors in China.Methods:Participants who delivered a live birth at 60 hospitals in 15 provinces in the eastern, central and western regions of China during July 2015 to June 2016 were interviewed by using structured questionnaire. Information on occurrence of unintended pregnancy within 2 years after delivery, postpartum contraceptive use, sexual resumption, breastfeeding, and women′s socio-demographic characteristics, and so on, were collected. Life-table analysis, cluster log-rank tests and a 2-level Cox regression model were used for data analysis.Results:A total of 18 045 postpartum women were investigated. The cumulative 1- and 2-year unintended pregnancy rates after delivery were 5.3% (95% CI: 4.5%－6.1%) and 13.1% (95% CI: 11.3%－14.8%), respectively. Cox regression model analysis showed that the risk of unintended pregnancy within 2 years postpartum were increased in younger women, ethnic minorities, women with abortion history, and those who had a vaginal delivery with short lactation time and late postpartum contraceptive initiation (all P<0.01). The risk of postpartum unintended pregnancy was not associated with geographic regions and hospitals where women gave a birth (all P>0.05). Conclusions:In China, the risk of unintended pregnancy within 2 years after delivery is relatively high. Service institutions and service providers should improve the quality of postpartum family planning services, promote the use of high effect contraceptive methods, and educate women to use a method at the time of their sexual resumption or even before.
