Aim To investigate the regulatory effects of 3-bromopyruvate (3-BrPA) on apoptosis and autophagy of fibroblast-like synoviocytes (FLS) in rats based on AMPK/mTOR signaling pathway and the underlying mechanism. Methods FLS of rats in vitro were cultured and induced by tumor necrosis factor-α (TNF-α) to construct a model of rheumatoid arthritis (R A). MTT assay was used to explore the optimal concentration of TNF-α and 3 -BrPA for induction and treatment of FLS. The effects of 3-BrPA on the migration and invasion of FLS were detected by Wound healing assay and Transwell assay. The apoptosis of FLS was tested by flow cytometry and mitochondrial membrane potential assay kit (JC-1). Moreover, FLS autophagic flux was detected by mCherry-EGFP-LC3B-overexpressed plasmids, and the expression of apoptosis/autophagy-related proteins as well as AMPK/mTOR pathway-related proteins were detected by Western blot. Results 3-BrPA (15 μmol • L) significantly inhibited the proliferation, migration, and invasion of FLS stimulated by TNF-a (25 μg • L

Aim To explore the potential mechanism of Dangshen Pingfei Huoxue decoction (DPHD) in the treatment of pulmonary fibrosis. Methods The common targets of DPHD and pulmonary fibrosis were obtained. Cytoscape software was used to construct " disease-drug-ingredients-targets " network diagram, and the common targets were imported into the STRING database for protein-protein interaction (PPI) analysis to screen out the core targets. In order to screen out key signaling pathways, the core genes were inputted into the DAVID platform for gene ontology (GO) and kyoto encyclopedia of genes genomes (KEGG) enrichment analysis. Then the molecular docking technology was used to verify the molecular docking between the core components and the key proteins in the signaling pathway. Finally, the molecular docking technology was used to verify the results of network pharmacology. Results A total of 176 active ingredients were obtained, and the top 5 was quercetin, kaempferol, luteolin, naringenin and p-sitosterol, respectively. A total of 116 common targets were obtained. A total of 21 core targets were finally obtained by PPI screening, and the top 5 was AKT1, CCND1, CASP3, MYC and IL1B, respectively. The results of GO enrichment analysis showed that DPHD was mainly involved biological processes of oxidative stress, proliferation and differentiation, transcriptional regulation, drug response and inflammatory response. The results of KEGG enrichment analysis indicated that the mainly signaling pathways included PI3K/Akt, MAPK, cellular senescence, AMPK, and TGF-beta. Molecular docking results showed that the binding energies of the top 5 active components of DPHD and the top 5 core targets were all less than-6.0 kcal • mo

This study explored the effect and mechanism of Maiwei Yangfei Decoction(MWYF) on pulmonary fibrosis(PF) mice. MWYF was prepared, and its main components were detected by ultra-high-performance liquid chromatography-triple quadrupole tandem mass spectrometry(UPLC-MS/MS). Male C57BL/6J mice were randomly divided into a control group, a model group, a pirfenidone(PFD) group, and low-, medium-, and high-dose MWYF groups, with 10 mice in each group. The PF model was induced in mice except for those in the control group by intratracheal instillation of bleomycin(BLM), and model mice were treated with saline or MWYF or PFD by gavage the next day. The water consumption, food intake, hair, and activity of mice were observed daily. The pathological changes in lung tissues were observed by hematoxylin-eosin(HE) staining, Masson staining, and CT scanning. The level of hydroxyproline(HYP) in lung tissues was detected by alkaline hydrolysis. Immunohistochemistry was used to observe the expression of collagen type Ⅲ(COL3) and fibronectin. The mRNA expression levels of α-smooth muscle actin(α-SMA), type Ⅰ collagen α1(COL1α1), COL3, and vimentin were detected by reverse transcription real-time fluorescence quantitative polymerase chain reaction(RT-qPCR). Superoxide dismutase(SOD) and malondialdehyde(MDA) kits were used to detect oxidative stress indicators in lung tissues and serum. The nuclear translocation of nuclear factor E2-related factor 2(Nrf2) protein was detected by immunofluorescence. The protein and mRNA expression levels of Nrf2, catalase(CAT), and heme oxygenase 1(HO-1) in lung tissues were detected by Western blot and RT-qPCR. Twelve chemical components were detected by UPLC-MS/MS. Animal experiments showed that MWYF could improve alveolar inflammation, collagen deposition, and fibrosis in PF mice, increase body weight of mice, and down-regulate the expression of fibrosis indexes such as HYP, α-SMA, COL1α1, COL3, fibronectin, and vimentin in lung tissues. In addition, MWYF could potentiate the activity of SOD in lung tissues and serum of PF mice, up-regulate the expression level of Nrf2, and promote its transfer to the nucleus, up-regulate the levels of downstream antioxidant target genes CAT and HO-1, and then reduce the accumulation of lipid metabolite MDA. In summary, MWYF can significantly improve the pathological damage and fibrosis of lung tissues in PF mice, and its mechanism may be related to the activation of the Nrf2 pathway to regulate oxidative stress.

Studies have investigated the effects of androgen deprivation therapy (ADT) use on the incidence and clinical outcomes of coronavirus disease 2019 (COVID-19); however, the results have been inconsistent. We searched the PubMed, Medline, Cochrane, Scopus, and Web of Science databases from inception to March 2022; 13 studies covering 84 003 prostate cancer (PCa) patients with or without ADT met the eligibility criteria and were included in the meta-analysis. We calculated the pooled risk ratios (RRs) with 95% confidence intervals (CIs) to explore the association between ADT use and the infection risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and severity of COVID-19. After synthesizing the evidence, the pooled RR in the SARS-CoV-2 positive group was equal to 1.17, and the SARS-CoV-2 positive risk in PCa patients using ADT was not significantly different from that in those not using ADT (P = 0.544). Moreover, no significant results concerning the beneficial effect of ADT on the rate of intensive care unit admission (RR = 1.04, P = 0.872) or death risk (RR = 1.23, P = 0.53) were found. However, PCa patients with a history of ADT use had a markedly higher COVID-19 hospitalization rate (RR = 1.31, P = 0.015) than those with no history of ADT use. These findings indicate that ADT use by PCa patients is associated with a high risk of hospitalization during infection with SARS-CoV-2. A large number of high quality studies are needed to confirm these results.

Objective: To investigate the efficacy and safety of enhanced recovery after surgery (ERAS) in perioperative management of patients with gallbladder carcinoma. Methods: The data of the patients with gallbladder carcinoma admitted at Peking Union Medical College Hospital between January 2017 and December 2021 were analyzed retrospectively. There were 69 males(42.1%) and 95 females(57.9%),with age of (64.0±10.3) years(range:37 to 89 years). Patients were divided into ERAS group(n=53) and normal group(n=111) according to whether they were treated with ERAS measures during the perioperative period.The basic characteristics of the two groups were matched by propensity score matching,and then the perioperative information was compared between the two groups. Categorical variables were presented as absolute numbers or frequencies. Differences between study groups were analyzed using χ2 test, Fisher's exact test, t-test, or Mann-Whitney U test, as appropriate. Results: Each group had 45 patients after propensity score matching with well-balanced basic characteristics. There was no difference in basic characteristics, operation time,bleeding,complication,and hospitalization expenses between two groups(all P>0.05). Compared with the normal group,time of ambulation (M(IQR)) (1(1) day vs. 2(2) days;Z=-3.839,P<0.01),postoperative anal exhaust time (2(1) days vs. 3(1) days;Z=-3.013,P=0.003),feeding time(2(1) days vs. 2(1) days;Z=-3.647,P<0.01),postoperative (5(2) days vs. 7(4) days;Z=-3.984,P<0.01) and total(8(4) days vs. 13(6) days;Z=-3.605,P<0.01) hospitalization time were shorter in ERAS group. Postoperative complications occurred in 12 patients. According to the Clavien-Dindo classification,6,4,and 2 patients were classified as grade Ⅰ,Ⅱ,and Ⅲa,respectively. Conclusion: The ERAS measures is safe and effective for perioperative management of patients with gallbladder carcinoma, enhancing patient recovery and shortening hospitalization time without increasing complication or hospitalization cost.
