    Abstract Acute lung injury (ALI) is a severe inflammatory disorder that has a high morbidity and mortality rate. Urolithin A (UA) is reported to have anti-inflammatory and anti-oxidative effects in ALI. However, its molecular mechanisms in ALI remain to be explored. Mice and BEAS-2B cells were administrated with lipopolysaccharide (LPS) to mimic the ALI model in vivo and in vitro. Hematoxylin-eosin (HE) staining was used to detect the pathological injury of lung tissues. The levels of proinflammatory cytokines in bronchoalveolar lavage fluid (BALF) and culture supernatant and the levels of oxidative stress markers in lung tissues were measured using ELISA. DCFH-DA probe was used to assess the reactive oxygen species (ROS) level. TUNEL staining and flow cytometry were performed to determine cell apoptosis. The key targets and pathways were confirmed by immunohistochemistry (IHC) and western blot. UA suppressed the pathologic damage, wet/dry weight ratio, and total protein and inflammatory cells in BALF. UA decreased neutrophil infiltration and proinflammatory cytokines production. UA reduced the level of malondialdehyde (MDA) and increased the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in pulmonary tissues. UA also inhibited cell apoptosis in lung tissues by decreasing Bax expression and increasing Bcl-2 expression. In addition, UA suppressed LPS-induced inflammatory factor production, ROS level, and cell apoptosis in BEAS-2B. Importantly, UA decreased the expression of HMGB1 in LPS-treated mice and BEAS-2B cells. HMGB1 overexpression greatly abrogated the inhibition of UA on inflammation, ROS, and cell apoptosis in LPS-administrated BEAS-2B. Furthermore, UA treatment suppressed the phosphorylated levels of p38, JNK, ERK, and p65 in LPS-administrated mice and BEAS-2B cells. UA alleviated lung inflammation, oxidative stress, and apoptosis in ALI by targeting HMGB1 to inactivate the MAPK/NF-κB signaling, suggesting the potential of UA to treat ALI.

    Abstract The addition of a co-catalyst is one of the most effective ways to enhance the performance of CdS photocatalytic hydrogen production. In this work, ternary photocatalysts with Defect MoS₂ and Ti₃C₂ acting synergistically on CdS are explored. The experimental results showed that the Defect MoS₂/Ti₃C₂/CdS photocatalyst had excellent photocatalytic hydrogen production performance of 14.1mmolh⁻¹g⁻¹, which was 18.5, 12.4, and 1.2 times higher than that of CdS, Ti₃C₂/CdS and Defect MoS₂/CdS, respectively. Defect MoS₂ and Ti₃C₂ synergistically interact with CdS and form heterojunctions, which improve the carrier separation efficiency and effectively suppress the recombination of photogenerated carriers. A possible photocatalytic hydrogen production mechanism of Defect MoS₂/Ti₃C₂/CdS is also proposed. The dual co-catalysts of Defect MoS₂ and Ti₃C₂ demonstrated in this paper provide a feasible approach for the development of composite catalysts.

    Abstract Background: The aim of this study was to discover the molecular mechanism of betulin palliative therapy for chronic obstructive pulmonary disease (COPD) based on the
    Methods: A COPD mouse model was developed. Changes in pulmonary ventilation function, pulmonary airway and vascular remodeling indicators, inflammatory cells, and inflammatory factors were determined after betulin intervention, and the pathological alterations of lung tissues were detected. An in vitro experimental model was constructed to observe the influence of betulin at varying concentrations on the proliferation of human bronchial epidermal cell line (16-HBE) cells and changes in inflammatory factors in cell supernatant. The expression levels of key proteins in 16-HBE cells transfected with overexpressed or silenced
    Results: After betulin intervention, pulmonary ventilation function in the 20 mg/kg betulin and 40 mg/kg betulin groups was improved. Levels of white blood cells (WBCs), neutrophils (Ns), tumor necrosis factor (TNF), TNF-ɑ, interleukin (IL)-1β, and IL-6 in the 2 groups also decreased significantly (all P<0.05). The pathological changes in COPD mice were detected. After betulin intervention, the pathological injury of the lung was reduced, the pathological score decreased significantly, and the remodeling indicators of pulmonary airway and pulmonary vessels diminished remarkably (all P<0.05). Betulin had no effect on the proliferation of 16-HBE cells in vitro. After cigarette smoke extract (CSE) stimulation, the rate of survival for 16-HBE cells decreased significantly. After betulin treatment, the survival rate of 16-HBE cells augmented remarkably, and the levels of TNF-ɑ, IL-6, and IL-1β in cell supernatant reduced substantially (all P<0.05). 16-HBE with overexpression and knockdown of
    Conclusions: Betulin relieved lung pathological injury, ameliorated lung ventilation function, and diminished the level of inflammatory factors in COPD mice, playing a therapeutic role via the

    Abstract Yiqi Yangyin Decoction (YYD) is a classic traditional Chinese medicine (TCM) formulation to treat lung cancer in clinic. Nevertheless, the active ingredients, key targets, and molecular mechanisms for YYD are still poorly understood. This study is focused on elucidating the pharmacological mechanism of YYD in non-small-cell lung cancer (NSCLC) by using a combined network pharmacology approach and biological experiment validation. Online bioinformatics tools showed that 40 bioactive compounds and 229 putative targets of YYD were associated with anti-NSCLC activity. Protein-Protein Interaction (PPI) network demonstrated AKT1, SRC, JUN, TP53, and EGFR as the top five key targets for YYD against NSCLC. Through enrichment analysis, YYD was found to affect cell proliferation and apoptosis in NSCLC possibly by PI3K-AKT signaling. Molecular docking confirmed a strong binding between the main compounds (quercetin or luteolin) and EGFR. As demonstrated by CCK-8, EdU, and colony formation assays, we found a significant inhibition of YYD on cell proliferation. Moreover, YYD treatment induced cell cycle arrest by affecting p53, p21, and cyclin D1 expression. YYD administration enhanced apoptosis by changing the expression of cleaved caspase-3, Bax, and Bcl-2. Mechanistically, YYD resulted in a significant inactivation of EGFR-PI3K-AKT signaling. Furthermore, EGFR activator significantly reversed YYD-mediated proliferation inhibition and apoptosis. YYD also showed an inhibitory effect on tumor growth in mice. Together, YYD might target the EGFR-PI3K-AKT pathway to repress NSCLC progression.

    Abstract In this work, a novel Mo vacancy defective MoS₂ loaded on CdS nanoparticles were obtained by a facile hydrothermal method. The photocatalytic performance of the prepared composites was evaluated from the perspective of decomposing water to produce H₂. The experimental result showed that the release rate of H₂ with defect MoS₂/CdS composites is 11,750 μmol g⁻¹h⁻¹, which is 1.3 and 15.3 times higher than that of MoS₂/CdS composites without defect (Mo) and pure CdS, respectively. The defective (Mo) vacancies formed on the MoS₂ surface due to partly oxidized by potassium permanganate. The synergistic interaction of defect MoS₂/CdS composites exhibited significant photocatalytic hydrogen production performance. The possible photocatalytic hydrogen production mechanism of the defect MoS₂/CdS was suggested. This study provides a new way to prepare efficient hydrogen production photocatalysts based on defective metal vacancy.

    Abstract Texture quality affects the sensory and market acceptance of fermentation minced pepper (FMP), but it will deteriorate during storage. Thus, high pressure processing (HPP) and thermal pasteurization (TP) were used to improve the texture quality of FMP during storage. The results showed that variations in texture quality and pectin characteristics under HPP and TP treatments were similar during storage. The hardness, cell wall material (CWM) and sodium carbonate‐soluble pectin (SSP) content, water‐soluble pectin (WSP) molecular weight (Mw) decreased, while WSP content and sodium chelate‐soluble pectin (CSP) Mw increased after storage. HPP‐treated FMP showed higher hardness (66.64–85.95 N) than that in TP‐treated one (57.23–62.72 N) during storage. Rhamnose (Rha), arabinose, mannose, and glucose were the crucial compositions in three pectins, and their total molar ratios, respectively, reached 89.19% and 87.97% after HPP and TP treatment. However, the molar ratio of most monosaccharide in three pectins decreased after storage. Atomic force microscope images indicated the short chains and branch structures increased but aggregates decreased in most pectin components during storage. Pearson correlation analysis demonstrated FMP hardness was extremely (p < 0.01) positively correlated with CWM and SSP content, and extremely (p < 0.01) negatively correlated with WSP content. Compared to TP treatment, HPP presented higher hardness, SSP content and Mw, Rha content, CSP Mw, and lower WSP content during storage. Hence, HPP was an effective method to improve the texture quality of FMP by maintaining pectin characteristics during storage. PRACTICAL APPLICATION: Softening is one of the main factors affecting market value and consumer preferences for FMP, and it is closely related to the modification and depolymerization of pectin. Changes of texture quality and pectin properties in HPP‐ and TP‐treated FMP during storage were assessed, including hardness, the content, monosaccharide compositions, Mw distribution, and nanostructure of WSP, SSP, and CSP. Compared to TP treatment, HPP could effectively improve the texture quality of FMP by inhibiting pectin degradation during storage. All the findings presented in this study would help to provide new insights into regulating the texture quality of FMP.

    Abstract Fiber membrane for adsorption organic pollutants from wastewater has attracted more and more attention because of its easy recovery performance. However, the adsorption properties of fiber membranes alone are not sufficient to effectively and quickly degrade pollutants. In this work, PAN/Bi₂MoO₆/Ti₃C₂ (PAN/BT) fiber membrane was prepared by electrospinning. The morphology, crystal structure and photocatalytic activity of the obtained membranes were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), photoelectron spectroscopy (XPS) and UV–visible spectrophotometer (UV–vis). The experimental results showed that it not only had high recovery performance but also good photocatalytic activity, and the best sample could effectively degrade 90.3% of tetracycline. After three times of photocatalytic regeneration, the removal rate is still about 80%. Its efficient catalytic performance comes from Bi₂MoO₆/Ti₃C₂ heterojunction. The Ti₃C₂ accelerates the separation and transfer of photogenerated electrons and effectively inhibits the recombination of photogenerated carriers. The films formed by PAN electrospinning are easy to recycle because of their good toughness. The construction of electrospinning membrane with composite photocatalyst is an easy and effective way to improve water environmental remediation pollution caused by tetracycline under visible light.

    Abstract Background: Previous studies have reported that rehabilitation training combined acupuncture (RTA) can be used for the treatment of limb hemiplegia (LH) caused by cerebral infarction (CI). However, its effectiveness is still unclear. In this systematic review study, we aim to evaluate the effectiveness and safety of RTA for LH following CI.
    Methods: We will retrieve the databases of CENTRAL, EMBASE, MEDILINE, CINAHL, AMED, CBM, PUBMED, and CNKI from inception to June 1, 2020 with no language restrictions. The randomized controlled trials of RTA for evaluating effectiveness and safety in patients with LH following CI will be included. Cochrane risk of bias tool will be used to measure the methodological quality for all included studies. Two authors will independently select the studies, extract the data, and assess the methodological quality of included studies. A third author will be invited to discuss if any disagreements exist between 2 authors. We will perform heterogeneity assessment before carrying out meta-analysis. According to the heterogeneity, we select random effect model or fixed effect model for meta-analysis of the included cohort studies. Cochrane risk of bias tool will be used to determine the methodological quality for included studies. RevMan 5.3 software (Cochrane Community, London, UK) will be utilized to perform statistical analysis.
    Results: This systematic review will assess the effectiveness and safety of RTA for LH caused by CI. The primary outcome includes limbs function, as measured by the Wolf Motor Function Test (WMFT) Assessment scale, or other associated scales. The secondary outcomes consist of muscle strength, muscle tone, quality of life, and any adverse events.
    Conclusion: The findings of this study will summarize the current evidence of RTA for LH caused by CI, and may provide helpful evidence for the clinical treatment.
    Dissemination and ethics: The findings of this study are expected to be published in peer-reviewed journals. It does not require ethical approval, because no individual data will be utilized in this study.
