Fermented traditional Chinese medicine(TCM) has a long history of medicinal use, such as Sojae Semen Praeparatum, Arisaema Cum Bile, Pinelliae Rhizoma Fermentata, red yeast rice, and Jianqu. Fermentation technology was recorded in the earliest TCM work, Shen Nong's Classic of the Materia Medica. Microorganisms are essential components of the fermentation process. However, the contamination of fermented TCM by toxigenic fungi and mycotoxins due to unstandardized fermentation processes seriously affects the quality of TCM and poses a threat to the life and health of consumers. In this paper, the characteristics, microbial composition, and mycotoxin profile of fermented TCM are systematically summarized to provide a theoretical basis for its quality and safety control.

Executive function(EF) is an advanced cognitive function of the central nervous system, and is closely related to an individual's capacity for daily living and adaptation. Patients with attention deficit hyperactivity disorder (ADHD) typically exhibit significant executive dysfunction. While most existing studies on the executive function of individuals with ADHD are cross-sectional, and little is known about the longitudinal maturation process of related brain structures and functional connectivity patterns. The findings indicate that ADHD patients exhibit differential developmental trajectories in brain structural and functional connectivity compared with typically developing group.Furthermore, there is a lifespan association between abnormal brain network development and ADHD symptoms. This article aims to elucidate the characteristics of executive function deficits in ADHD patients across different developmental stages, examining their relationship with the nervous system’s development from a development perspective.

To investigate the effect of capsaicin(CAP)on the replication of bovine viral diarrhea vi-rus(BVDV).Bovine nasal turbinate osteoblasts(BT)infected with BVDV served as the research model,and viral gene and protein levels were evaluated using RT-qPCR and Western blot.Moreo-ver,molecular docking,molecular dynamics simulation,and oil red O staining were applied to ana-lyze the mechanism by which CAP inhibits BVDV replication.The results revealed no significant effect of CAP at 6.25,12.5,25,and 50 mg/L on the viability of BT cells.CAP was found to signifi-cantly inhibit BVDV 5′UTR RNA and E2 protein levels,according to the antiviral effect study.Molecular docking and molecular dynamics simulations indicated that CAP could bind with high affinity to the active site of PI3K.Additional mechanistic studies indicated that CAP significantly reduced the activation of the PI3K/AKT signaling pathway triggered by BVDV.Furthermore,CAP notably decreased the mRNA levels of FASN,SREBP-1,and ACC-1,which are crucial fatty acid synthesis enzymes in the downstream PI3K/AKT signaling pathway,as well as the levels of lipid droplets.Interestingly,the addition of exogenous oleic acid greatly diminished the antiviral effec-tiveness of CAP and significantly lowered the mRNA levels of IFN-α and IFN-β.The results reveal for the first time that CAP can inhibit BVDV replication,establishing a foundation for its preven-tion and the development of feed additives.

OBJECTIVE To investigate the mechanism of inhibition of breast cancer lung metastasis by Shugan Yishen Recipe by studying the effects of Shugan Yishen Recipe(SGYSR)on gene expression in the lung microenvironment of mice with breast cancer.METHODS A high metastasis model of breast cancer was constructed,and the mice were randomly divided into saline group,low,medium,high(0.5,1,2 g·kg-1)Shugan Yishen Recipe groups,and docetaxel group(5 mg·kg-1),and intervened for 28 days.HE staining was used to observe the lung tissue structure;transcriptome analysis was performed on the metastatic foci,and the key differential gene expression was screened by bioinformatics analysis of the GO and KEGG pathway characteristics of the gene ex-pression profiles,and the expression of key immune genes was analyzed by qPCR and Western blot.The expression of MDSCs was de-tected by flow cytometry;the expression of cytokines and chemokines including Cxcl2,and GM-CSF was detected by ELISA.RE-SULTS Compared with the saline group,the number of metastatic nodules in lung tissues of the middle and high dose groups of Shu-gan Yishen Recipe and docetaxel group were correspondingly lower;HE staining suggested that the degree of lung pathology was im-proved.There were 814 differentially expressed genes in the lung microenvironment of the high-dose group of Shugan Yishen Recipe and the saline group,of which 713 genes were down-regulated and 101 genes were up-regulated;screening for key inflammatory medi-ator genes in the Shugan Yishen Recipe group,Nfkbiz,Tnfaip3,Maff,Hspa1a,Hspb1 and Cxcl2,the inflammatory genes in the Shu-gan Yishen Recipe,as compared with that of the saline group,were significantly down-regulated(P<0.05,P<0.01),and ultimately its results were consistent with the trend of the transcriptome results.Western blot was used to verify the results at the protein level,and it was found that compared with the saline group,the protein expression levels of Nfkbiz,Tnfaip3,Maff,Hspa1a and Cxcl2 in the Shugan Yishen Recipe group were decreased(P<0.05,P<0.01),while the protein expression of Hspb1 was up-regulated(P<0.01).Both the Shugan Yishen Recipe group and the docetaxel group could inhibit the expression of MDSCs(P<0.001),and the ex-pression of Cxcl2,and GM-CSF decreased to a certain extent(P<0.05,P<0.01).CONCLUSION Shugan Yishen Recipe can in-hibit breast cancer lung metastasis and regulate the lung immune microenvironment genes in a wide range.

Objective:To evaluate the outcomes of intensive conservative treatment compared to conventional conservative treatment in patients with acute aortic syndrome(AAS).Methods:The study prospectively enrolled consecutive patients with AAS who were admitted to Beijing Anzhen Hospital, affiliated with Capital Medical University, and Beijing Dawanglu Emergency Rescue Hospital from January 2024 to December 2024. These patients with surgical contraindications or refused surgery for various reasons opted for conservative treatment. A total of 282 patients were included, and 15 patients with missing data or those who died without any treatment were excluded. Finally, 267 patients were enrolled, of whom 94 received intensive conservative treatment, and 173 received conventional conservative treatment, the inverse probability of treatment weighting (IPTW) was used to reduce the influence of confoundings. After adjusting of baseline datas via IPTW, the survival outcomes of the two groups were compared at 14 days, 30 days, and at the end of follow-up.Results:The results showed significant differences in acute phase survival rates between the enhanced conservative treatment group and the conventional conservative treatment group at 14 days(82.40%vs.53.20%, P<0.0001). Significant survival differences were also observed at 30 days and at 276-day mid-term follow-up (96.29% vs.51.60%, P<0.0001; 78.50% vs.48.50%, P<0.0001). In the subgroup analysis, for type A aortic dissection, the enhanced conservative treatment group had higher survival rates compared to the conventional conservative treatment group at 14, 30 and 276 days (63.46% vs.41.35%, P<0.05; 52.17% vs.37.90%, P<0.05; 50.00% vs. 31.97%, P<0.05). However, for type B aortic dissection, although the enhanced conservative treatment group had higher survival rates than the conventional conservative treatment group, no statistically significant differences were observed (96.29% vs. 80.00%, P=0.054; 95.65% vs.78.37%, P=0.067; 94.12% vs.74.20%, P=0.088). Conclusion:For patients diagnosed with AAS are forced to choose conservative treatment if emergency surgery is not possible in the first place, intensive conservative treatment strategies can significantly reduce the mortality in the acute phase compared with conventional conservative treatment. Mid-term follow-up, intensive conservative treatment still has a significant survival advantage.

Fear of disease progression(FoP)is a common psychological state among patients with coronary heart dis-ease(CHD),which exists throughout the course of disease and seriously affects the prognosis.High level of FoP not only harms the mental health of patients but also do not benefit their rehabilitation after discharge.This concept was first proposed by foreign researchers studying the psychological state of cancer patients.In recent years,there have been numerous studies on the influencing factors and qualitative aspects of FoP in CHD patients,while related inter-vention studies remain few.This paper reviews the concept,scales and related influencing factors of FoP,providing ideas for medical staff to provide targeted interventions for CHD patients.
