Objective To develop a health-promoting lifestyle scale for women with polycystic ovary syndrome （PCOS），and to test its reliability and validity，and preliminarily apply it. Methods Based on the Pender health promotion model，the item pool of the scale was constructed through literature research，semi-structured interviews and group discussions. After 2 rounds of Delphi expert consultation and pre-survey，the initial scale was formed. From April to July 2022，316 patients with PCOS in the health management center，reproductive medicine center and endocrinology department of a tertiary hospital in Nanjing were selected for item analysis，exploratory factor analysis and reliability test，respectively. From August to October 2022，358 PCOS patients were selected for confirmatory factor analysis. From November 2022 to February 2013，294 PCOS patients were selected，and the scale was used to investigate the status of health-promoting lifestyle in PCOS patients. Results The health-promoting lifestyle scale for PCOS patients included 5 dimensions and 33 items. The total content validity index of the scale was 0.942，and the content validity index of each item was 0.810-1.000. 5 common factors were extracted by 2 exploratory factor analyses，and the cumulative variance contribution rate was 62.399%. Confirmatory factor analysis showed that the model fit was good. The Cronbach’s α coefficient of the total scale was 0.930；the split-half reliability was 0.842；the test-retest reliability was 0.888. The preliminary application results showed that the total score of health-promoting lifestyle in PCOS patients was（96.925±14.273），and the average score of items was （2.937±0.433），which was at a medium level. Conclusion The health-promoting lifestyle scale for PCOS patients has good reliability and validity，which can be used as a tool for medical staff to assess the level of health-promoting lifestyle of PCOS patients，and can help nurses to quickly identify the level and dimensions of health-promoting lifestyle of patients，so as to formulate individualized precise health management plans.

Objective To construct a lifestyle management scheme for infertile women with polycystic ovary syndrome（PCOS） during outpatient medical treatment，and to evaluate its clinical effects. Methods Based on the evidence summary and qualitative interviews，a lifestyle management scheme for infertile women with PCOS during medical treatment was constructed. The infertile women at childbearing age with PCOS from the health management center and reproductive medicine center of a tertiary A hospital in Nanjing were recruited through convenience sampling. 27 patients who visited the above mentioned 2 centers from September 15 to 30，2021 were recruited in an experimental group successively，while another 27 patients who visited there from February 15 to 28，2021 were recruited in a control group successively. Next，the lifestyle management scheme was implemented in the experimental group in 9 key steps，including evaluation，screening，status analysis，formulation of body mass management objectives，diet management，exercise management，behavior management，health guidance，and evaluation. Meanwhile，27 patients in the control group were given the routine healthy lifestyle guidance. After 3 months，the figure of BMI，insulin resistance index，serum testosterone，anxiety，depression and quality of life of the 2 groups were analysed. Results After the intervention，the BMI of the experimental group was 24.43±2.99，which was lower than （26.48±3.49） in the control group. The insulin resistance index was 2.42±0.98，which was lower than 3.52±0.97 in the control group. The level of testosterone was（0.55±0.19） ng/ml，which was lower than（1.20±0.42） ng/ml in the control group. The anxiety level was（5.73±2.13） and the depression level was（5.12±2.66），which were lower than（9.40±2.36） and（10.60±2.58） of the control group. The score of disease-related quality of life was（140.38±7.25），which was higher than（115.56±7.99） of the control group，and the differences were statistically significant （P<0.05）. Conclusion The implementation of the lifestyle management scheme for infertile women with PCOS during medical treatment is conducive to adjust patients’ endocrine and metabolic status，alleviate their anxiety and depression and improve quality of life.

This article aims to summarize the experience in the nursing care of an 8-year-old child with sitosterolemia. The mainly nursing points are as follows：to formulate a personalized diet list,to restrict the intake of plant sterols and some animal sterols;to monitor the growth and development indicators and assess nutritional status;to observe and record changes in xanthomas and reduce their disturbance;to closely observe the condition to prevent complications;to strengthen psychological care for the child and family members to relieve their negative emotions;to conduct regular follow-up and continued care to improve disease management capabilities of the child and his family. After 20 months of continuous follow-up,the patient’s condition improved without any complications.

Objective To construct a hypoglycemia nursing decision support system and to explore its application in clinical practice. Methods This study firstly established a nursing decision support system of hypoglycemia,and realized functions such as intelligent entry,intelligent reminding,and assistant decision making. The medical records before the application of the system（from January to March 2018） and after it（from October to December 2018） were selected to compare the incidences of hypoglycemia and the completion of nursing documents. 117 nurses were enrolled to investigate their satisfaction with the system by self-designed satisfaction questionnaires. Results After applying the hypoglycemia nursing decision support system,the recurrence rate of hypoglycemia decreased from 7.05% to 3.33%,and the difference was statistically significant（χ ²=8.253,P=0.004）. The completion rate of nurses’ documents increased from 68.17% to 94.23%,and the difference was statistically significant （χ ²=137.303, P<0.001）. 117 questionnaires were collected,and the average score for each dimension was over 2.50. The results showed that nurses were more satisfied with the overall system. Conclusion The establishment of a hypoglycemia nursing decision support system can reduce the recurrence rate of hypoglycemia,improve the quality of clinical nursing documents and the efficiency of clinical nurses,and increase the satisfaction of nurses.
