Objective:To evaluate the effects of smart stethoscope on the monitoring childhood asthma exacerbation, so as to assist family management in childhood asthma.Methods:A prospective randomized controlled study was carried out.A total of 80 children with asthma who were treated at Department of Pediatric Respiratory, Xinhua Hospital, Shanghai Jiao Tong University School of Medicine and Shanghai Tonxin Pediatric Clinic from November 2020 to May 2021 were enrolled and randomly divided into a test group of 40 cases (used the smart stethoscope) and a control group of 40 cases(not used the smart stethoscope). Medical history data were collected.The control group received monthly routine follow-up, while the test group was followed up both routinely and by smart stethoscope.In the test group, hearing wheezing sound was regarded as asthma exacerbation, and in the control group, the asthma exacerbation was reported by the parents themselves.The frequency of asthma exacerbation, asthma control level and quality of life were compared between the two groups.The recognition, diagnosis, treatment and outcomes of acute asthma exacerbation in two groups of children were described and analyzed.Measurement data were analyzed by t test or Mann- Whitney U test.Numeration data were analyzed by χ2 test. Results:Respiratory sounds collected by smart stethoscope in the test group were assessed by 3 specialist physicians.There were 12 wheezing rales (42.86%), 1 moist rale (3.57%) and 1 rhonchi rale (3.57%). Besides, 12 files (42.86%) were difficult to distinguish, and 2 files (7.14%) induced inconsistent identification.The number of asthma exacerbation was 12 in the test group and 5 in the control group.In the test group, 12 were recognized by the smart stethoscope, and only 6 were recognized by the parents.Comparing the diagnosis and treatment measures between two groups, it was found that there were more children in the test group (38.1%) receiving home treatment through telemedicine than those in the control group (20.0%). Besides, there were less children (61.9%) in the test group receiving unplanned hospital treatment (including unplanned outpatient, emergency and hospitalization) than those in the control group (80.0%). There was no statistically significant difference between the two groups of children during acute asthma exacerbation ( χ2=4.67, P=0.097). Parents were satisfied with the common functions, convenience and stability of smart stethoscope. Conclusions:Smart stethoscope can acquire the respiratory sounds of children with asthma in real time, achieving timely detection, diagnosis and treatment of asthma exacerbation in children.What′s more, smart stethoscope reduces the incidence of unplanned hospital diagnosis and treatment, and assists parents with better family management of children asthma.
2.The role and mechanism of Clq/tumor necrosis factor related protein family in sepsis
Chinese Pediatric Emergency Medicine 2023;30(7):545-548
Clq/tumor necrosis factor related proteins(CTRPs)are a newly discovered superfamily of proteins with wide tissue distribution and diverse biological functions, which are involved in the regulation of glucose and lipid metabolism, vascular endothelial cell function and inflammatory response.There are few studies on the relationship between CTRP family and sepsis, and a few studies have shown that some CTRP family members are involved in the occurrence and development of sepsis.This review introduced the role of CTRP family in sepsis and related mechanism.

Objective:To explore the feasibility and optimization effect of modifying the Henry Ford Hospital (HFHS) RapidPlan model for stereotactic body radiation therapy planning based on local requirements.Methods:The following changes were made based on Henry Ford Health System(HFHS) Rapid Plan Lung SBRT model, taking the latest clinical guideline evidence and local clinical practice into account: Internal gross target volume(IGTV) and organ at risk(OAR) structure, lung, were added and set corresponding parameters.The upper value of planning target volume (PTV) was adjusted from 109% to 125%. The original training library was replaced with 73 local historical simultaneous integrated boosting plans, and statistical verification and outlier cleaning of the initial trained model were performed using Model Analytics software. Totally 10 cases not included in the model library were selected for independent verification, and automatic optimization result of the models before and after modifying were compared under the same beam condition. The following dosimetric parameters were compared after target dose normalization: conformal index (CI) of target volume, the mean doses, maximum doses and dose-volume parameters of OARs.Results:The " tail" of the PTV′s DVH and the " shoulder" and " tail" of the IGTV′s DVH of model M (local) validation plan (M (local)_P) performs higher than the original model HFHS (HFHS_P). The PTV_CI (1.07±0.13) of M local_P were significantly smaller than HFHS_P (1.25±0.24) ( Z=-2.497, P<0.05). Except for Heart_ D15 cm 3 and Heart_ Dmax, most of the M local_P dosimetric parameters of OARs were lower than HFHS_P, and the standard deviation was smaller. However, the difference of between two plans was no more than 3.06%. 10 HFHS_P plans don′t satisfy dose parameters requirement, two of which PTV_CI values are 1.52 and 1.74, far beyond the clinically acceptable range. Conclusions:Commercial model HFHS could be localized by replacing training library and adjusting parameters. Moreover, plans optimized by the modified model are local clinical acceptable in the aspects of target volume conformity and hotspots, and have a better performance in terms of OAR sparing and plan consistency.

ZNF804A rs1344706 has been identified as one of the risk genes for schizophrenia. However, the neural mechanisms underlying this association are unknown. Given that ZNF804A upregulates the expression of COMT, we hypothesized that ZNF804A may influence brain activity by interacting with COMT. Here, we genotyped ZNF804A rs1344706 and COMT rs4680 in 218 healthy Chinese participants. Amplitudes of low-frequency fluctuations (ALFFs) were applied to analyze the main and interaction effects of ZNF804A rs1344706 and COMT rs4680. The ALFFs of the bilateral dorsolateral prefrontal cortex showed a significant ZNF804A rs1344706 × COMT rs4680 interaction, manifesting as a U-shaped modulation, presumably by dopamine signaling. Significant main effects were also found. These findings suggest that ZNF804A affects the resting-state functional activation by interacting with COMT, and may improve our understanding of the neurobiological effects of ZNF804A and its association with schizophrenia.
