Smoothened Agonist in vitro Methods The expression of TOP2A mRNA in normal liver tissues and HCC tissues and its significance for survival and prognosis of HCC patients were analyzed by BioGPS, GEPIA and Kaplan-Meier Plotter databases. The coexpression gene of TOP2A and its GO function were analyzed using GENE and Metascape databases, along with the KEGG pathway enrichment analysis. The correlation between TOP2A and microsatellite instability (MSI) and DNA repair gene was analyzed by Sangerbox database. Then, the correlation between TOP2A gene and CD4+ T cells and various immune cells was analyzed by TISIDB and TIMER database, and analysis was also performed regarding the effect of CD4+ T cells on the survival and prognosis of HCC patients. Results TOP2A mRNA is not significantly expressed in normal liver tissues and CD4+ T cells, but is significantly expressed in HCC tissue, which is not conducive to the survival and prognosis of patients. The GO function of TOP2A coexpression gene is mainly enriched in cell mitosis and cell proliferation, while KEGG is mainly enriched in cell cycle and platinum drug resistance pathway. The expression of TOP2A is positively correlated with MSI, MSH2 and MSH6 of DNA repair gene, the purity of tumor cells and the numbers of various immune cells. All kinds of immune cells reported certain copy number variation in HCC, but only the numbers of CD4+ T cells showed a significant effect on the survival and prognosis of HCC patients. Conclusion There is a significant positive correlation between the expression of TOP2A mRNA and the number of CD4+T cells in HCC, which is not conducive to the survival and prognosis of HCC patients.Objective To analyze the differentially expressed genes (DEGs) in patients with poor response to ursodeoxycholic acid (UDCA) therapy and to provide theoretical basis for the treatment of primary biliary cholangitis (PBC). Methods The GEO database was searched to obtain UDCA response related gene chip dataset. The DEGs were screened and the protein-protein interaction (PPI) network was constructed. The enrichment analysis of the biological function and signaling pathway of DEGs were carried out with the use of DAVID database. The CIBERSORT deconvolution algorithm was used to analyze the infiltration of 22 kinds of immune cells. Finally, Coremine database was used to predict traditional Chinese medicine (TCM) by analyzing the DEGs that were not only related to UDCA response, but also related to the immune cell infiltration. Results By analyzing the gene chips from UDCA responders and UDCA poor-responders, 99 DEGs were obtained. Biological function and signaling pathway enrichment analysis showed that the up-reginfiltration.Objective To investigate the effect of baicalin on acute lung injury (ALI) induced by lipopolysaccharide (LPS), and to explore the roles of M1/M2 polarization of pulmonary macrophages and M1/M2 macrophage-mediated inflammation in the effect. Methods Sixty SD rats were divided into six groups normal control group, LPS group, (10, 50, 100) mg/kg baicalin combined with LPS group, and dexamethasone (DEX) group. ALI models were established by intratracheal instillation of LPS. After 24 hours, bronchoalveolar lavage fluid (BALF) and bilateral lung tissues were collected. The pathological changes of rat lung tissue were observed by HE staining, and the wet/dry mass ratio (W/D) of lung tissue was measured; the contents of IL-1β, IL-6, TNF-α, and IL-10 in BALF were detected by ELISA; the M1 macrophage marker inducible nitric oxide synthase (iNOS) and the M2 macrophage marker CD206 in CD68 positive macrophages were detected by immunofluorescence cytochemical staining; the mRNA expressions of iNOS, IL-1β, Arg1, and CD206 were detected by real-time PCR, and the protein expressions of iNOS and Arg1 were detected by Western blot analysis. Results Baicalin significantly reduced lung lesions and lung water content in ALI rats, and down-regulated the secretion levels of pro-inflammatory cytokines TNF-α, IL-6, and IL-1β, while up-regulated the secretion of anti-inflammatory cytokine IL-10 in BALF. Baicalin significantly inhibited the lung macrophage polarization to M1 phenotype, and promoted the polarization to M2 phenotype. Baicalin significantly decreased the mRNA and protein expression levels of IL-1β and iNOS, while increased the mRNA and protein expression levels of CD206 and Arg1 in lung tissues. Conclusion Baicalin can inhibit the lung macrophage polarization to M1 phenotype, promote the polarization to M2 phenotype, and reduce the M1/M2 ratio, thereby alleviating the LPS-induced pulmonary inflammatory response in ALI rats.Objective To investigate the effects of ox-LDL/β2GPI/anti-β2GPI antibody complex on apoptosis and inflammatory factors expression in RAW264.7 cells and its mechanism. Methods RAW264.7 cells were treated with medium, ox-LDL, β2GPI/aβ2GPI antibody complex, ox-LDL/β2GPI complex, ox-LDL/aβ2GPI antibody complex, and ox-LDL/β2GPI/aβ2GPI antibody complex separately. The role of signaling pathways was investigated by TLR4 inhibitor TAK-242 and mTOR inhibitor rapamycin. Finally, cells were stimulated with different concentrations of TNF-α. The apoptosis was detected by Annexin V-FITC/PI double labeling. The mRNA expressions of TNF-α and IL-1β were detected by real-time quantitative PCR, and the protein expressions of TNF-α, IL-1β, and apoptosis-related proteins cleaved-caspase-3 (c-caspase-3) and Bcl2 were detected by Western blot. Results Ox-LDL/β2GPI/aβ2GPI antibody complex promoted RAW264.7 cells' apoptosis, with a decrease in protein Bcl2 and an increase in protein cleaved-caspase-3, and enhanced the level of inflammatory factors, while apoptosis and the expression of inflammatory factors were partially reduced when macrophages had been pre-treated with inhibitors. TNF-α up-regulated apoptosis in RAW264.7 cells at 100 ng/mL and 200 ng/mL. Conclusion Ox-LDL/β2GPI/aβ2GPI antibody complex induces apoptosis in RAW264.7 cells by increasing the expression of inflammatory factors. TLR4 and mTOR pathways are involved in the process.
This study aimed to assess the associations between maternal drug use, cytochrome P450 (
) genetic polymorphisms, and their interactions with the risk of congenital heart defects (CHDs) in offspring.
A case-control study involving 569 mothers of CHD cases and 652 controls was conducted from November 2017 to January 2020.
After adjusting for potential confounding factors, the results show that mothers who used ovulatory drugs (adjusted odds ratio [a

1.00-2.40), or traditional Chinese drugs (a
= 1.97; 95%
1.26-3.09) during pregnancy were at a significantly higher risk of CHDs in offspring. Maternal
genetic polymorphisms at rs1065852 (A/T
. A/A
= 1.53, 95%
1.10-2.14; T/T
A/A

1.07-2.31) and rs16947 (G/G
C/C
= 3.41, 95%
1.82-6.39) were also significantly associated with the risk of CHDs in offspring. Additionally, significant interactions were observed between the
genetic variants and drug use on the development of CHDs.
In those of Chinese descent, ovulatory drugs, antidepressants, antiabortifacients, and traditional Chinese medicines may be associated with the risk of CHDs in offspring. Maternal
genes may regulate the effects of maternal drug exposure on fetal heart development.

This study aimed to examine the associations of daytime napping with incident risks of cardiovascular diseases (CVDs) and hypertension (HTN).
Data for napping and CVD outcomes in 25 provinces were collected from baseline (2010) and three waves of follow-up (2012-2017) investigations of the China Family Panel Studies. Cox frailty models with random intercepts for the surveyed provinces were used to assess the longitudinal effects of daytime napping on CVD and HTN.
Compared with non-nappers, 30+ min nappers had higher risks of CVD and HTN, while no significant associations were observed among < 30 min nappers. Incident risks among 30- to < 60-min nappers increased by 22% [hazard ratio (HR) 1.22, 95% confidence interval (
) 1.08-1.39] for CVD and 21% (1.21, 1.04-1.41) for HTN, respectively, with corresponding HRs of CVD and HTN of 1.27 (1.09-1.47) and 1.38 (1.16-1.65) among ≥ 60 min nappers. Nap-associated CVD risks varied by subgroups, with stronger associations in participants with lower body mass index (< 24 kg/m
), physically inactive persons, smokers, and participants with longer nighttime sleep (≥ 7 h/night).
