Using a sample of 106 million 𝜓(3686) decays, 𝜓(3686)→𝛾𝜒𝑐𝐽(𝐽=0,1,2) and 𝜓(3686)→𝛾𝜒𝑐𝐽,𝜒𝑐𝐽→𝛾𝐽/𝜓(𝐽=1,2) events are utilized to study inclusive 𝜒𝑐𝐽→anything, 𝜒𝑐𝐽→hadrons, and 𝐽/𝜓→anything distributions, including distributions of the number of charged tracks, electromagnetic calorimeter showers, and 𝜋0s, and to compare them with distributions obtained from the BESIII Monte Carlo simulation. Information from each Monte Carlo simulated decay event is used to construct matrices connecting the detected distributions to the input predetection “produced” distributions. Assuming these matrices also apply to data, they are used to predict the analogous produced distributions of the decay events. Using these, the charged particle multiplicities are compared with results from MARK I. Further, comparison of the distributions of the number of photons in data with those in Monte Carlo simulation indicates that G-parity conservation should be taken into consideration in the simulation.
Background: Gan–Dou–Fu–Mu decoction (GDFMD) improves liver fibrosis in experimental and clinical studies including those on toxic mouse model of Wilson disease (Model). However, the mechanisms underlying the effect of GDFMD have not been characterized. Herein, we deciphered the potential therapeutic targets of GDFMD using transcriptome analysis.
Methods: We constructed a tx-j Wilson disease (WD) mouse model, and assessed the effect of GDFMD on the liver of model mice by hematoxylin and eosin, Masson, and immunohistochemical staining. Subsequently, we identified differentially expressed genes (DEGs) that were upregulated in the Model (Model vs. control) and those that were downregulated upon GDFMD treatment (compared to the Model) using RNA-sequencing (RNA-Seq). Biological functions and signaling pathways in which the DEGs were involved were determined by gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathway analyses. A protein–protein interaction (PPI) network was constructed using the STRING database, and the modules were identified using MCODE plugin with the Cytoscape software. Several genes identified in the RNA-Seq analysis were validated by real-time quantitative PCR. Results: Total of 2124 DEGs were screened through the Model vs. control and Model vs. GDFMD comparisons, and dozens of GO and KEGG pathway terms modulated by GDFMD were identified. Dozens of pathways involved in metabolism (including metabolic processes for organic acids, carboxylic acids, monocarboxylic acids, lipids, fatty acids, cellular lipids, steroids, alcohols, eicosanoids, long-chain fatty acids), immune and inflammatory response (such as complement and coagulation cascades, cytokine–cytokine receptor interaction, inflammatory mediator regulation of TRP channels, antigen processing and presentation, T-cell receptor signaling pathway), liver fibrosis (such as ECM-receptor interactions), and cell death (PI3K-Akt signaling pathway, apoptosis, TGF-beta signaling pathway, etc.) were identified as potential targets of GDFMD in the Model. Some hub genes and four modules were identified in the PPI network. The results of real-time quantitative PCR analysis were consistent with those of RNA-Seq analysis. Conclusions: We performed gene expression profiling of GDFMD-treated WD model mice using RNA-Seq analysis and found the genes, pathways, and processes effected by the treatment. Our study provides a theoretical basis to prevent liver fibrosis resulting from WD using GDFMD.
Six new species of Zaischnopsis Ashmead (Hymenoptera: Eupelmidae) from China are described, Zaischnopsis covid Jiang & Peng sp. nov., Zaischnopsis fuscolivida Tang & Peng sp. nov., Zaischnopsis lii Jiang & Peng sp. nov., Zaischnopsis pacis Jiang & Peng sp. nov., Zaischnopsis campaniformis Tang & Peng sp. nov., and Zaischnopsis zhongi Jiang & Peng sp. nov. All the new species are described and illustrated based on females, and partial mitochondrial cytochrome oxidase subunit I (COI) sequences are provided for the six new species as well as for the previously described Z. fumosa Peng & Xiang. Females of all the species of Zaischnopsis recorded from China are differentiated in a key.
