Objective:
To analyze the characteristics of a norovirus outbreak in a kindergarten, and factors affecting the detoxification time, so as to provide a scientific basis for targeted control measures.
Methods:
On February 24,2023, the basic personal information, clinical manifestations,morbidity and treatment of 16 kindergarten cases with a norovirus outbreak in Wuhan were collected. Anal swabs were collected every 7 d after the outbreak to detect norovirus. Chisquare test was used for comparison of intergroup rates. The comparison of detoxification time between different groups was conducted by Logrank test, and the influencing factors of detoxification time in cases were analyzed by Cox multiple regression analysis.
Results:
From February 19-28, 2023, a total of 18 cases were reported and 16 of them participated in the detoxication time monitoring. In the first, second, third and fourth sampling after the outbreak, the positive rates were 60.00%, 100.00%, 75.00% and 0, respectively. The reverse transcriptionpolymerase chain reaction cycle threshold (Ct values) were (25.83±5.74, 28.83±5.55, 36.13±4.30), and undetected, respectively. The median time of detoxification was 19.42 d with 95%CI=(18.21-20.64)d. The results of Cox regression showed that the detoxication time was shorter in the treatment group than in the nontreatment group[HR(95%CI)=5.09(1.39-18.58), P<0.05].
Conclusion
Children infected with norovirus has a long duration of detoxification,and case management, which could be shortened by drugs, and disinfection should be strengthened after the case returned to school.

It is believed that children bronchiolitis obliterans (BO) is located at the lung and closely related to the spleen and kidney. Phlegm, stasis, block and deficiency are the main pathogenesis. This article promotes staged differentiation and treatment of BO considering the clinical manifestations and pathogenesis characteristics. The attack stage is dominated by phlegm and stasis blocking the lung, for which the method of dissolving phlegm and dispelling stasis, relieving cough and calming panting should be used; Xiaoqinglong Decoction(小青龙汤) and Sanzi Yangqin Decoction (三子养亲汤) with modifications and selfmade Modified Wuhu Decoction (五虎汤加味) are recommended for cold-phlegm blocking the lung syndrome and phlegm heat blocking the lung syndrome, respectively. In sustained stage, the upper excess and lower deficiency together with phlegm-stasis blocking the lung are the pathogenesis, for which the method of dissolving phlegm and dispelling stasis, reopening the block and supplementing deficiency is suggested, and Xiaoqinglong Decotion (小青龙汤) and Duqi pills (都气丸) with modifications can be used. In convalescent stage, the pathogenesis is lung-spleen-kidney depletion with residual pathogen. It suggested to supplement the deficiency and consolidate the root, as well as clear the residual pathogen, for which Baogen NO.1 Decoction (宝根1号方) with modifications can be used.

OBJECTIVE
To elucidate the possible mechanism, and to explore the main components, core targets, and key signaling pathways of Haimufang Decoction(HMF) in treating non-small cell lung cancer(NSCLC) by the network pharmacology and serum pharmacology methods.
METHODS
TCMSP and DisGeNET databases were used to search and summarize the components, targets and non-small cell lung cancer-related targets of HMF, respectively. The common targets were obtained by intersection of drug targets and disease targets, and uploaded to the STRING data platform to construct a protein-protein interaction(PPI) network to screen core targets. GO and KEGG enrichment analysis of core targets were performed using DAVID database. Cytoscape 3.9.1 software was used to construct the network of "HMF flavor-components-targets-pathways", predicting the possible mechanisms of action of HMF. Finally, the cell cycle arrest and apoptosis induction experiments of HMF-containing serum on NSCLC NCI-H1975 cells were used to verify the effect of HMF on lung cancer and its potential mechanism.
RESULTS
A total of 65 compounds were identified from HMF, and 47 main compounds such as 24-keto-cholesterol, quercetin and diisobutyl phthalate were screened out. PPI network analysis shown that tumor protein p53, tumor necrosis factor, cystein-asparate protease-3 and other 55 proteins might be the core target proteins of HMF in the treatment of NSCLC, involving multiple signaling pathways such as pathways in cancer. In subsequent validation experiments, cell cycle arrest and apoptosis induction in the pathways in cancer pathway have been shown to be involved in the inhibition of non-small cell lung cancer.
CONCLUSION
HMF plays a role in the treatment of NSCLC through multi-component, multi-target and multi-channel signaling pathways, which provides a theoretical basis for the mechanism and clinical application of HMF.

Background::Liver cancer is largely resistant to chemotherapy. This study aimed to identify the effective chemotherapeutics for β-catenin-activated liver cancer which is caused by gain-of-function mutation of catenin beta 1 ( CTNNB1), the most frequently altered proto-oncogene in hepatic neoplasms. Methods::Constitutive β-catenin-activated mouse embryonic fibroblasts (MEFs) were established by deleting exon 3 ( β-cateninΔ(ex3)/+ ), the most common mutation site in CTNNB1 gene. A screening of 12 widely used chemotherapy drugs was conducted for the ones that selectively inhibited β-cateninΔ(ex3)/+ but not for wild-type MEFs. Untargeted metabolomics was carried out to examine the alterations of metabolites in nucleotide synthesis. The efficacy and selectivity of methotrexate (MTX) on β-catenin-activated human liver cancer cells were determined in vitro. Immuno-deficient nude mice subcutaneously inoculated with β-catenin wild-type or mutant liver cancer cells and hepatitis B virus ( HBV); β-cateninlox(ex3)/+ mice were used, respectively, to evaluate the efficacy of MTX in the treatment of β-catenin mutant liver cancer. Results::MTX was identified and validated as a preferential agent against the proliferation and tumor formation of β-catenin-activated cells. Boosted nucleotide synthesis was the major metabolic aberration in β-catenin-active cells, and this alteration was also the target of MTX. Moreover, MTX abrogated hepatocarcinogenesis of HBV; β-cateninlox(ex3)/+ mice, which stimulated concurrent Ctnnb1-activated mutation and HBV infection in liver cancer. Conclusion::MTX is a promising chemotherapeutic agent for β-catenin hyperactive liver cancer. Since repurposing MTX has the advantages of lower risk, shorter timelines, and less investment in drug discovery and development, a clinical trial is warranted to test its efficacy in the treatment of β-catenin mutant liver cancer.
