ABSTRACT
AIM To determine the contents of chemical consituents in Lycii Fructus from Qaidam Basin.METHODS Spectrophotometry was adopted in the content determination of polysaccharides,total flavonoids and carotenoid.HPLC was applied to the content determination of betaine and scopoletin.Kjeldahl method was used for the content determination of protein.Then principal component analysis was performed.RESULTS The contents of carotenoid,betaine and scopoletin in samples from six growing areas showed obvious differences (P ＜ 0.05),while those of polysaccharides,total flavonoids and protein exhibited no obvious differences (P ＞ 0.05).The contents of various constituents in samples at three picking time also had no obvious differences (P ＞ 0.05).The comprehensive score of principal components of samples from Delingha City was the highest,followed by that from Ulan County.CONCLUSION The quality of Lycii Fructus from Qaidam Basin from Delingha City is the best.
ABSTRACT
Objective To observe the influence of nursing intervention on postpartum depression and breastfeeding compliance in primipara.Methods From August 2013 to April 2015,146 women received cesarean section in North Jiaochang Branch of Hanzhong Central Hospital were randomly divided into intervention group and control group with 73 cases in each group.The control group was treated with routine nursing measures,and the intervention group with both routine care and nursing intervention.Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS) were used to evaluate the negative emotions of maternal postpartum.Breastfeeding Self-Efficacy Scale (BSES) were used to evaluate the confidence of maternal breast feeding.The breast feeding compliance between the two groups was compared.The breast feeding rates of the two groups were compared in 1 week and 1 month after discharge.Results Compared with the control group,the SDS and SAS scores of the intervention group were significantly lower (P＜0.05).The breastfeeding confidence of the intervention group was significantly better than the control group and the difference was statistically significant (P＜0.05).The compliance of breast feeding of the intervention group was 97.26％ significantly higher than that of the control group (78.08％)with a statistically significant difference (P＜0.05).After one-week and one-month follow-up,the rate of breastfeeding of the intervention group was significantly higher than that of the control group (95.89％ VS 83.56％;91.78％ VS 72.60％,P＜0.05).Concltsion The nursing intervention measures for primipara after cesarean section can significantly break bad mood,enhance maternal breastfeeding confidence,increase the rate of breastfeeding compliance and are worthy of promotion.
ABSTRACT
Objective To develop clinical dual-qualification nursing teachers stressors scale. Methods Based on literature review, semi-structured interview and the Delphi, first of all, the item pool was made up, then the pre-test scale was formatted. 167 dual-qualification nursing teachers participated in this investigation.Finally, the official scale was formed after measuring its reliability and validity. Results The scale was made up of six dimensions and 25 items. The Cronbach's α was 0.652 ～ 0.903, and the intraclass correlation coefficient was 0.716 ～ 0.921. Conclusion The process of this scale is scientific, rational, rigorous. The scale has good psychometric characteristics and can be used for the stress assessment of dual-qualification nursing teachers.
