Internet healthcare represents a new form of online medical services for patients,evolved from traditional physical hospitals through the integration of digital technology.Currently,China's conventional medical services confronts numer-ous challenges,with an unmet demand for high-quality and convenient healthcare services.In this context,the progression of in-ternet hospitals aligns with the requirements of modern social development in China.Despite this,the construction of China's in-ternet hospital remains nascent.As a forerunner in digital transformation initiatives,Shanghai,recognized as the"international digital capital",offers a fertile ground for such explorations.This study presents S Hospital in Shanghai as a model case,summa-rizing the development process,highlights and challenges encountered in the construction of its internet hospitals.It distills opti-mization strategies from the vantage points of hospital management and governmental authorities,aiming to provide insights into advancement of Shanghai's healthcare sector.

Objective: To construct and determine the weight of Index System for Assessing Parent s Ability on Child Injury Prevention, and to provide the basis for childhood injury intervention in family. Methods: Twenty four experts majored in related fields were invited to participate in Delphi consultation. The final index system was constructed according to the consulting results and the weight of primary and secondary indicators were calculated. Results: The final index system consisted of 5 subscales corresponding to 5 age groups: 0,1-2,3-5,6-11 and 12-17 years old. Each scale included 4 primary indicators and 11 secondary indicators. The weight of primary indicators obtained by analytic hierarchy process is 0.28 for "environment", 0.16 for "product", 0.31 for "behaviors and skills", and 0.25 for "psychology". The highest weight of secondary indicators for "environment", "product" and "behaviors and skills" was "water area", while the top secondary indicators for "psychology" included "parental style""emotional control" "family atmosphere", with all indicators weighted higher than 0.2. Conclusion The Index System for Assessing Parent s Ability on Child Injury Prevention by Delphi consultation is comprehensive in content, and with the focus on parental behaviors and skills on injury prevention.

Objective: To review the articles evaluating parental ability on child injury prevention and to provide suggestions for developing assessment index for parental ability on child injury prevention. Methods: Relevant studies were retrieved from the Chinese Biomedical Literature Database (CBM), Wanfang, CNKI, VIP, PubMed, Medline, Springer, and Web of Science, and were reviewed based on instruments, contents, as well as reliability and validity of instruments. Results: A total of 47 articles were included for analysis. The methods for assessment mainly include quantitative and qualitative investigation, mainly quantitative surveys through scales or questionnaires. Assessment contents mainly included parental knowledge, attitudes and practice on child injury prevention(44 papers), as well as home safety(3 papers).The evaluation object mainly concentrated on parents of preschool children. A small part of studies tested the reliability and validity of the instruments in quantitative investigations.The reliability test indexes included retest reliability and Kronbach coefficient, and the validity test indexes included content validity, structure validity and scale validity. Conclusion There is a lack of assessment tools for evaluating parents ability on child injury prevention in Chinese background. The development of corresponding assessment tools should consider the characteristics of children in different age groups, injury types, as well as its reliability and validity.

Objective: To investigate child injury prevention practice and associated factors among parents of primary school students. Methods: Parents of 2 577 students were selected from three primary schools in three administrative regions of Shanghai by multi stage sampling method between May and June in 2021. Questionnaire survey was administered to parents based on the Index System for Assessing Parent s Ability on Child Injury Prevention, which was developed previously by the present research group. Results were converted into standardized scores for descriptive analysis, and the original scores were analyzed by multiple linear regression model. Results: The standardized scores of parents on environment safety, product safety, behaviors and skills and psychological safety were (0.91±0.08)(0.93±0.08)(0.97±0.04)(0.95±0.05), respectively. The standardized score of general ability was (0.95±0.04). The standardized scores on knowledge, attitude and practice of injury prevention were (0.99±0.03)( 0.97± 0.05)(0.89±0.10), respectively. Mothers performances were generally better than fathers . Parents with higher education performed better than those with lower education. Parents with "being a parent" in mind performed better on child injury prevention. Conclusion There is a gap between practice with the knowledge as well as attitude towards child injury prevention among parents of primary school students. Parenting role, educational background and parental awareness of the importance of parental role are primary factors that affect child injury prevention practice.

Objective: To explore the dose-response relationship between duration of emotional experience of primary school students and the intensity of anxiety disorders, and to understand the risk of anxiety disorders corresponding to different emotional state levels. Methods: A total of 7 152 primary students from grade 3 to 5 were investigated with questionnaire survey from 16 public primary schools, by using the Screen for Child Anxiety Related Emotional Disorder (SCARED) and Positive Affect and Negative Affect Scale. Results: The prevalence of anxiety disorders was 19.91%, among which the prevalence rates of anxiety disorders in boys and girls were 19.41% and 20.43%, respectively. After adjusting for gender, grade, household register, the only child, parental marital status, parental occupation, parental educational level, family financial level, serving as a class leader, receiving special training or counseling in sports and art, and being bullied, the risk of anxiety disorder in children with positive emotions lasting for 7-16 days, 17-24 days and >24 days was lower compared to those with positive emotions lasting for less than 6 days(P<0.05); the risk of anxiety disorder in children with negative emotions lasting for 0.27-0.93 day, 0.94-2 days and >2 days was higher compared to those with negative emotions lasting less than 0.26 day(P<0.05). Restricted cubic spline analysis showed that the duration of emotional state and anxiety disorder showed a significant non-linear dose-response relationship (non-linear test, P<0.01), that is, as the number of days of positive emotions increases, the risk of anxiety disorder continues to decrease, and as the number of days of negative emotions increases, the risk of anxiety disorder continues to increase. Conclusion There is a significant dose-response relationship between the duration of the emotional state of primary school students and the prevalence of anxiety disorders. Acquirement and maintain positive emotions m be an important entry point for mental health promotion among primary school students.

Objective:To investigate the effects of sodium fluoride on growth and development and serum oxidative stress of offspring rats.Methods:Twenty-four clean female SD rats and 24 clean male SD rats were selected, weighting 180 - 220 g, and mating in the same cage for 10 d according to 1 ∶ 1 for male and female. According to body weight by random number table method, the female rats were divided into control group, low-dose fluoride group, and high-dose fluoride group, 8 rats in each group. They were drunk 0, 100 and 200 mg/L sodium fluoride solution prepared with purified water, respectively, and they all ate standard feed. The female rats were exposed to fluoride from the 0th day of pregnancy to the 3rd week after the offspring rats were born (before weaning). After weaning, 10 female offspring rats were selected from each group and continued to be exposed to fluoride in the same amount and manner until the 12th week after birth. The body weight, body length and hind limb length of the offspring rats were measured every week before weaning and every two weeks after weaning. After 12th week of exposure to fluoride, blood samples were taken from abdominal aortas to detect the levels of serum superoxide dismutase (SOD), malondialdehyde (MDA), inducible nitric oxide synthase (iNOS), glutathione peroxidase (GSH-Px) and total antioxidant capacity (T-AOC).Results:At the 2nd week after birth, the body weight [(24.87 ± 3.36) g], body length [(6.37 ± 0.52) cm] and hind limb length [(2.27 ± 0.13) cm] of the offspring rats in high-dose fluoride group were lower than those in control group [(29.23 ± 4.19) g, (6.92 ± 0.47), (2.44 ± 0.16) cm, P < 0.05], but there was no statistically significant difference between low-dose fluoride group and control group and high-dose fluoride group ( P > 0.05). At 3rd to 12th weeks after birth, the body weight, body length and hind limb length of the offspring rats in high-dose fluoride group were lower than those in low-dose fluoride group and control group ( P < 0.05), the low-dose fluoride group were lower than those in control group ( P < 0.05). Serum SOD, GSH-Px and T-AOC levels in control group [(176.51 ± 29.55), (985.23 ± 164.80) U/ml, (0.864 ± 0.167) mmol/L] were higher than those in low-dose fluoride group [(127.98 ± 24.41), (776.53 ± 107.85) U/ml, (0.639 ± 0.110) mmol/L] and high-dose fluoride group [(99.75 ± 14.56), (425.14 ± 78.67) U/ml, (0.441 ± 0.072) mmol/L], the levels of MDA and iNOS [(3.37 ± 0.73) nmol/ml, (189.00 ± 44.67) pg/ml] were lower than those in low-dose fluoride group [(8.22 ± 1.38) nmol/ml, (305.60 ± 73.41) pg/ml] and high-dose fluoride group [(14.81 ± 1.81) nmol/ml, (431.00 ± 91.19) pg/ml], the differences were statistically significant ( P < 0.05); the levels of serum SOD, GSH-Px and T-AOC in high-dose fluoride group were lower than those in low-dose fluoride group, and the levels of MDA and iNOS were higher than those in low-dose fluoride group ( P < 0.05). Conclusion:Excessive fluoride can increase the serum oxidative stress level of offspring rats, which may affect the growth and development of offspring rats.

OBJECTIVETo investigate the status of exclusive breastfeeding(EBF) and possible influencing factors during 0-7 days postpartum in China.

METHODSDuring 2011 to 2013, healthy mothers and neonates who were in the period of 0- 7 days postpartum from 8 provinces across different regions of China were recruited to take the questionnaire investigations and physical examinations. Information about socio-economic, pregnant, and delivery status, infant healthy situation and feeding indicators was collected to calculate the rate of exclusive breastfeeding during 0- 7 days postpartum and analyze the influencing factors.

RESULTSA total of 1 882 pairs of mothers and neonates were covered by this study. The rate of EBF was 13.3% (250 cases) during 0- 7 days postpartum. Bottle feeding (OR=0.08, 95% CI: 0.05- 0.12), the mothers themselves mixed fed at their 0-4 months old (OR=0.22, 95%CI: 0.08-0.58), the mothers who had used methods to stimulate milk secretion (OR=0.58, 95% CI: 0.35- 0.94) might decrease the EBF rate. Compared with the mothers who believed that their breast milk was not enough for their infants, the mothers who believed breastmilk was enough may increase the EBF rate (OR=6.04, 95%CI: 3.34-10.94). Comparing to the EBF rate of Beijing, Yunnan (OR=0.10, 95%CI: 0.04-0.24), and Gansu(OR=0.03,95%CI: 0.01-0.08) had lower EBF rate during 0-7 days postpartum. What's more, the EBF rate increased with the increasing neonates' age (OR=1.33, 95% CI: 1.16- 1.53).

CONCLUSIONThe EBF rate during 0- 7 days postpartum is still low in China and had significant differences in different regions. Suboptimal feeding knowledge and practices affected the EBF rate significantly.
