Objective To investigate the value of interrupter resistance (Rint) pulmonary function testing in the diagnosis of asthma in preschool children,and to compare the significance of Rint pulmonary function testing versus impulse oscillometry (IOS) in the diagnosis of asthma. Methods A prospective study was conducted among 108 children with recurrent wheezing,aged 4 to<6 years,who were admitted from July 2022 to November 2023. According to the treatment outcome,they were divided into an asthmatic group (61 children) and a non-asthmatic group (47 children). Rint pulmonary function parameters and IOS parameters were analyzed for both groups,and the two tests were compared in terms of feasibility and diagnostic value. Results Compared with the non-asthmatic group,the asthmatic group had significantly higher percentage of actual measured value to predicted value for Rint and percent changes in the measured value and predicted value of Rint (P<0.05). The receiver operating characteristic curve analysis showed that the percent change in the predicted value of Rint had an optimal cut-off value of 32.0％ in the diagnosis of asthma in preschool children,with an area under the curve (AUC) of 0.705,a sensitivity of 41.0％,and a specificity of 91.5％ (P<0.05). In terms of the degree of completion,18 children (16.7％) failed to complete the IOS test,but they could successfully complete Rint pulmonary function testing with good quality control. Rint pulmonary function testing and IOS had a similar area under the curve in the diagnosis of asthma in preschool children (P>0.05). Conclusions Rint pulmonary function testing can be used to assist in the diagnosis of asthma in preschool children,with a similar diagnostic value to IOS and a relatively high level of feasibility. A percent change of ≥32％ in the predicted value of Rint in the bronchial dilation test can be used as a cut-off value for the diagnosis of asthma in preschool children.

OBJECTIVES: To explore the relationship between the height of alveolar bone resorption and sex and age in the adolescent dentition. METHODS: Multi-slice computed tomography (MSCT) was used to measure the height of alveolar bone resorption at labial, lingual, mesial and distal sites of teeth in 149 adolescents aged from 10 to 20 years. SPSS 25.0 software was used to analyze the relationship between the height of alveolar bone resorption and sex and age. RESULTS: There was no significant difference in the height of alveolar bone resorption between sex (P>0.05). The height of alveolar bone resorption was positively correlated with age in all types of teeth. The model constructed by combining the alveolar bone resorption height data of four sites (y=2.569x₁+3.106x₂+4.108x₃+1.451x₄-0.082, R²_max=0.756)had a better ability to infer age than that of combining two sites (y=5.942x₁+4.489x₂+0.612, R²_max=0.706) and a single site (R²_max=0.638). CONCLUSIONS The height of alveolar bone resorption is positively correlated with the age of adolescents. The combination of four sites has a stronger ability to infer the relationship between the height of alveolar bone resorption and age in adolescents and has higher accuracy in practical application.

AIM: To analyze the chemical ingredients of Qingxin-zishen prescription decoction (QZPD) and predict its main pharmacodynamic substances and mechanism in the prevention and treatment of menopause syndrome (MPS) with the help of high performance liquid chromatography-quadrupole-time of flight mass spectrometry (HPLC-Q-TOF/MS) combined with network pharmacology. METHODS: The chemical ingredients of QZPD were identified after analyzing the retention time, exact mass, secondary mass spectrometry fragmentation and other information obtained from HPLC-Q-TOF/MS and comparing them with the established chemical ingredients database and the literatures. The targets of ingredients in QZPD were predicted by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and SwissTargetPrediction database. The disease targets of MPS were obtained through Online Mendelian Inheritance in Man (OMIM) and GeneCards Database. Gene ontology (GO) function enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of potential targets were analyzed with the Metascape database. Cytoscape 3.7.2 software was used to construct the network of active components-key targets-pathways. AutoDockTools 4.2.5 software was applied in the molecular docking verification between the key active components and key targets. RESULTS: A total of 83 components were identified in QZPD and 847 drug targets were predicted. After intersection them with 3 050 disease targets, 395 common targets were obtained. After network topology analysis, 74 key targets were obtained, involving mitogen-activated protein kinase (MAPK), phosphatidylinositol-3 kinase/protein kinase B (PI3K/Akt), transforming growth factor-β (TGF-β) and other signaling pathways. Molecular docking analysis results indicated that 23 key active components, such as berberine, epiberberine, coptisine, geissoschizine methyl ether, liensinine, norcoclaurine, palmatine, quercetin, and luteolin, had good binding activity with several of the key targets. CONCLUSION: This study preliminarily identifies the potential effective chemical ingredients of QZPD, predicts its targets in the prevention and treatment of MPS, which provides supporting information for the further study of the pharmacodynamic substances and mechanisms of QZPD.

Brucea javanica oil emulsion (BJOE) has been used to treat tumor in China for more than 40 years. However, its components and effectiveness in the treatment of acute lymphocytic leukemia (ALL) and its mechanism of anti-cancer activity remain unknown. In the current study, high-performance liquid chromatography-evaporative light scattering detector (HPLC-ELSD) was used to analyze the components of BJOE. Then, the anti-leukemia effects of BJOE were examined both in vitro and in vivo using ALL Jurkat cells and the p388 mouse leukemia transplant model, respectively. The primary ALL leukemia cells were also used to confirm the anti-leukemia effects of BJOE. The apoptotic-related results indicated that BJOE induced apoptosis in Jurkat cells and were suggestive of intrinsic apoptotic induction. Moreover, BJOE inhibited Akt (protein kinase B) activation and upregulated its downstream targets p53 and FoxO1 (forkhead box gene, group O-1) to initiate apoptosis. The activation of GSK3β was also involved. Our findings demonstrate that BJOE has anti-leukemia effects on ALL cells and can induce apoptosis in Jurkat cells through the phosphoinositide3-kinase (PI3K) /Akt signaling pathway.
