Exploring the mechanism of Xiaoaiping Injection inhibiting autophagy in prostate cancer based on proteomics

Chinese Journal of Natural Medicines 2025年第1期23卷 64-76页

Xiaoaiping(XAP) Injection demonstrates the anti-prostate cancer(PCa) effects, yet the underlying mechanism remains unclear. This study aims to investigate the impact of XAP on PCa and elucidate its mechanism of action. PCa cell proliferation was evaluated using a cell counting kit-8(CCK-8) assay. Cell apoptosis was assessed through Hoechst staining and Western blotting assays. Proteomics technology was employed to identify key molecules and significant signaling pathways modulated by XAP in PCa cells. To further validate potential key genes and important pathways, a series of assays were conducted, including acridine orange(AO)staining, transmission electron microscopy, and immunofluorescence assays. The molecular mechanism of XAP against PCa in vivo was examined using a PC3 xenograft mouse model. Results demonstrated that XAP significantly inhibited cell proliferation in multiple PCa cell *** C4-2 and prostate cancer cell line-3(PC3) cells, XAP induced cellular apoptosis, evidenced by reduced B-cell lymphoma 2(Bcl-2) levels and elevated Bcl-2-associated X(Bax) levels. Proteomic, immunofluorescence, and quantitative reverse transcription-polymerase chain reaction(q RT-PCR) investigations revealed a strong correlation between forkhead box O3a(Fox O3a) autophagic degradation and the anti-PCa action of XAP. XAP hindered autophagy by reducing the expression levels of autophagy-related protein 5(Atg5)/autophagy-related protein 12(Atg12) and enhancing Fox O3a expression and nuclear translocation. Furthermore,XAP exhibited potent anti-PCa action in PC3 xenograft mice and triggered Fox O3a nuclear translocation in tumor tissue. These findings suggest that XAP induces PCa apoptosis via inhibition of Fox O3a autophagic degradation, potentially offering a novel perspective on XAP injection as an effective anticancer therapy for PCa.

Objective: To examine the effectiveness of Chinese medicine(CM) Lianhua Qingwen Granule(LHQW) and Jingyin Gubiao Prescription(JYGB) in asymptomatic or mild patients with Omicron infection in the shelter hospital. Methods: This single-center retrospective cohort study was conducted in the largest shelter hospital in Shanghai, China, from April 10, 2022 to May 30, 2022. A total of 56,244 asymptomatic and mild Omicron cases were included and divided into 4 groups, i.e., non-administration group(23,702 cases), LHQW group(11,576 cases), JYGB group(12,112 cases), and dual combination of LHQW and JYGB group(8,854 cases). The length of stay(LOS) in the hospital was used to assess the effectiveness of LHQW and JYGB treatment on Omicron infection. Results: Patients aged 41–60 years, with nadir cycle threshold(CT) value of N gene sults of factorial design ANOVA proved that the LHQW/JYGB combination therapy synergistically shortened LOS(P=0.032). Conclusions: Patients with a nadir CT value <25were more likely to accept CM. The LHQW/JYGB combination therapy could shorten the LOS of Omicron-infected individuals in an isolated environment.

Effect of heat treatment on microstructure and mechanical properties of a novel Al-Zn-Mg-Cu alloy

引用

China Foundry 2025年

作者： yan-mei yang Xin-chen Tang Ye-fei Li xue-wei Fang Da-wei Yi Zhi-yun Zhang Qiao-ling Zheng Zhi-xi Wang Guo-yu Zhang su Zhang Hao Cheng yang He Yi-bo Liu Zi-han Wu Ya-nan Chen Yi-min Gao State Key Laboratory for Mechanical Behavior of Materials Xi'an Jiaotong University Xi'an Aerospace Precision Electromechanical Institute

Effects of solution and aging treatment on the microstructure and mechanical properties of a novel Al-Zn-Mg-Cu alloy by microalloying rare elements Sc and Er were studied. The results show that solution time has a visible influence on the microstructure and mechanical properties of the alloy. Specifically, as the solution time increases, the area fraction of the residual phase in the alloy decreases, and the shape of the grain becomes more spheroidal and coarser, leading to a decrease in hardness. This is attributed to the dissolution of strengthening phases during the solution treatment, which weakens the solid solution strengthening *** single-stage aging treatment shows an initial increase in strength and hardness of the alloy, followed by a decrease as the aging time is extended, until a steady state is achieved. The optimal single-aging conditions are found to be at 120 ℃ for 24 h, where the alloy exhibits an excellent combination of high strength and good ductility, with an ultimate tensile strength(UTS) of 523 MPa, yield strength(YS) of 482 MPa, and elongation(El)of 1.75%, respectively. Compared to single-stage aging, double-stage aging(120 ℃ for 24 h and then 150 ℃ for 52 h) significantly increases the elongation of the alloy(4.17%), but the UTS reduces to 465.29 MPa, and YS reduces to 410.64 MPa. Transmission electron microscopy(TEM) observations disclose that the grain size, the distribution spacing of precipitates along the grain boundary, and the width of the precipitation-free zone(PFZ) all undergo augmentation as the duration of the second stage aging process elongates.
