RESUMO
Background: Parental health literacy is important to children's health and development, especially in the first 3 years. However, few studies have explored effective intervention strategies to improve parental literacy. Objective: This study aimed to determine the effects of a WeChat official account (WOA)-based intervention on parental health literacy of primary caregivers of children aged 0-3 years. Methods: This cluster randomized controlled trial enrolled 1332 caregiver-child dyads from all 13 community health centers (CHCs) in Minhang District, Shanghai, China, between April 2020 and April 2021. Participants in intervention CHCs received purposefully designed videos via a WOA, which automatically recorded the times of watching for each participant, supplemented with reading materials from other trusted web-based sources. The contents of the videos were constructed in accordance with the comprehensive parental health literacy model of WHO (World Health Organization)/Europe (WHO/Europe). Participants in control CHCs received printed materials similar to the intervention group. All the participants were followed up for 9 months. Both groups could access routine child health services as usual during follow-up. The primary outcome was parental health literacy measured by a validated instrument, the Chinese Parental Health Literacy Questionnaire (CPHLQ) of children aged 0-3 years. Secondary outcomes included parenting behaviors and children's health outcomes. We used the generalized linear mixed model (GLMM) for data analyses and performed different subgroup analyses. The ß coefficient, risk ratio (RR), and their 95% CI were used to assess the intervention's effect. Results: After the 9-month intervention, 69.4% (518/746) of caregivers had watched at least 1 video. Participants in the intervention group had higher CPHLQ total scores (ß=2.51, 95% CI 0.12-4.91) and higher psychological scores (ß=1.63, 95% CI 0.16-3.10) than those in the control group. The intervention group also reported a higher rate of exclusive breastfeeding (EBF) at 6 months (38.9% vs 23.44%; RR 1.90, 95% CI 1.07-3.38) and a higher awareness rate of vitamin D supplementation for infants younger than 6 months (76.7% vs 70.5%; RR 1.39, 95% CI 1.06-1.82). No significant effects were detected for the physical score on the CPHLQ, breastfeeding rate, routine checkup rate, and children's health outcomes. Furthermore, despite slight subgroup differences in the intervention's effects on the total CPHLQ score and EBF rate, no interaction effect was observed between these subgroup factors and intervention factors. Conclusions: Using a WHO literacy model-based health intervention through a WOA has the potential of improving parental health literacy and EBF rates at 6 months. However, innovative strategies and evidence-based content are required to engage more participants and achieve better intervention outcomes.

Background: Parental health literacy is an important determinant of children's health, especially during the critical window of early development in the first 3 years. As the information communication technology develops, health education via social media is widely used to deliver health information. However, few studies have explored the effect of intervention via social media on parental health literacy. Objective: This study aims to determine whether a WeChat official account-based health intervention can improve parental health literacy of primary caregivers of children aged 0 to 3 years in Minhang District, Shanghai, China. Methods: The cluster randomized controlled trial includes all 13 community health centers (CHCs) in Minhang District, Shanghai. We take each CHCs as a cluster in the randomization. The CHCs are randomly allocated to the intervention or the control group through random sequence generation. Ninety primary caregivers of children aged 0 to 2 years will be recruited from each CHC, 1170 in total. Caregivers in the intervention group will be provided with a series of video clips and online reading material links on scientific parenting via a WeChat account. Caregivers in the control group will receive printed educational materials with similar contents to the intervention group. All the participants will access routine child health care and be followed up for 9 months. Online assessment of health literacy will be conducted for both groups before and after the intervention. The primary outcome is the change in the total scores of parental health literacy using a validated instrument. The data of secondary outcomes, such as exclusive breastfeeding in the first 6 months, anthropometric measurements, and disease conditions, will be extracted from routine health care records. Generalized linear mixed model (GLMM) will be used for data analyses. Discussion: Compared with traditional health education, health intervention via WeChat official account could be a feasible and effective solution to improve parental health literacy. Trial registration: This trial is registered with the Chinese Clinical Trial Registry (ChiCTR): (#ChiCTR2000031711) on April 07, 2020.

Two dimeric abietane diterpenoids, salviwardins A and B (1 and 2), and a seco-abietane diterpenoid salviwardin C (3), along with five known analogues (4-8), were isolated from the roots of Salvia wardii. The structures of these isolates were elucidated by extensive spectroscopic methods. The inhibitory activities of these isolates against five human cancer cell lines in vitro were also tested.
RESUMO
Hyperuralone A (1), a polycyclic polyprenylated acylphloroglucinol possessing an unprecedented tetracyclo-[5.3.1.1(4,9).0(4,11)]-dodecane core, was characterized from Hypericum uralum together with hyperuralone B (2), a congener with another complex caged skeleton. Their structures were determined by extensive spectroscopic analysis and ECD calculations. A plausible biosynthetic pathway of their intriguing architectures via intramolecular Diels-Alder reactions was also proposed. Compound 1 exhibited obviously cytotoxic activities against five human cancer cell lines in vitro (IC50 4.6-14.4 µM).
