Objective To compare the costs of Danmu extract syrup and Xiaoer Chiqiao Qingre granules for the treatment of acute upper respiratory tract infection (AURI) in children. Methods We conducted this prospective cohort study from July 2018 to June 2020. Children with AURI in the pediatric outpatient department and emergency department of West China Second Hospital were enrolled, and were divided into two groups: Danmu extract syrup group (Danmu group) and Xiaoer Chiqiao Qingre granule group (Chiqiao group) according to the treatment. The pharmacoeconomic evaluation took the medical and health system as the research perspective and considered direct medical costs, including registration fees, drug fees, inspection fees, testing fees, and treatment fees. A cost-effectiveness analysis or a cost minimization analysis was adopted according to the results of efficacy between the two groups. Results We enrolled 1 036 children with AURI. After propensity score matching, 252 in the Danmu group and 253 in the Chiqiao group were included. There was no statistically significant difference in the symptom recovery time between the two groups. The cost minimization analysis showed that the total costs (median difference −21.55) and drug costs (median difference −7.24) of the Danmu group were significantly lower than those of the Chiqiao group (P<0.001). The results of the subgroup and sensitivity analyses were consistent with the primary analysis. Conclusion Danmu extract syrup is a cost-saving alternative compared with Chiqiao granules for AURI in children.

A great number of studies have demonstrated functional abnormalities in children with attention-deficit/hyperactivity disorder (ADHD), although conflicting results have also been reported. And few studies analyzed homotopic functional connectivity between hemispheres. In this study, resting-state functional magnetic resonance imaging (MRI) data were recorded from 45 medication-naïve ADHD children and 26 healthy controls. The regional homogeneity (ReHo), degree centrality (DC) and voxel-mirrored homotopic connectivity (VMHC) values were compared between the two groups to depict the intrinsic brain activities. We found that ADHD children exhibited significantly lower ReHo and DC values in the right middle frontal gyrus and the two values correlated with each other; moreover, lower VMHC values were found in the bilateral occipital lobes of ADHD children, which was negatively related with anxiety scores of Conners' Parent Rating Scale (CPRS-R) and positively related with completed categories of Wisconsin Card Sorting Test (WCST). Our results might suggest that less spontaneous neuronal activities of the right middle frontal gyrus and the bilateral occipital lobes in ADHD children.

Objective To update and form an instrument for evaluating clinical applicability of guidelines (version 1.0). Methods We updated the systematic review of global guideline clinical applicability evaluation instruments to form the initial item list and carried out Delphi expert consultation to establish the instrument for evaluating clinical applicability of guidelines (version 2.0). Results The general structure of version 2.0 was consistent with that of version 1.0, which included 12 evaluation items belonging to five domains covering accessibility, readability, acceptability, feasibility, and an overall evaluation. Moreover, some new items were added in version 2.0, such as "The guideline does not provide supporting tools or resources and the operation is poor", "After the guideline implementation, the expected effects of diagnosis and treatment do not be achieved", " Medical staff in your workplace believe that the guideline is not necessary because they have sufficient medical experience, etc.", "Lack of authority of the organizations and personnel that developed the guideline" and "Medical staff in your workplace are reluctant to change the original medical practice". Conclusion This study updated and formed an instrument for evaluating clinical applicability of guidelines (version 2.0), which is able to better assess the applicability of new clinical guidelines and greatly promote more appropriate guidelines into practice.
Rational drug use is a global concern. As one of the highest risk groups for drug use, children's rational drug use has always been concerned.
