In order to accurately and quickly identify the anti-explosion safety risk of the group buildings outside the plant boundary of the major hazards, firstly, based on the urban disaster risk system theory and disaster risk management concept, an anti-explosion safety risk assessment index system of group buildings was established. The four assessment dimensions include explosive hazard, explosive vulnerability, anti-explosion safety capacity and anti-explosion response capacity. Secondly, an anti-explosion safety risk assessment model based on the extension connection cloud is constructed. It eliminates the uncertainty generated by the cross-fertilization of multiple risk information and realizes the quantitative assessment of the anti-explosion safety risk level of group buildings. Finally, in order to verify the effectiveness of the assessment methodology, the assessment process is applied to group buildings outside the major hazards of explosives-type hazardous chemicals in a city. The results show that the method can quickly and effectively assess the level of anti-explosion safety risk of group buildings. The method reliably and intuitively reflects the anti-explosion deficiencies of group buildings. It provides decision-making support for the anti-explosion safety planning and construction of group buildings outside major hazards enterprises. [ABSTRACT FROM AUTHOR]

BACKGROUND: At present, bone marrow mesenchymal stem cells are the main seed cells used in cell therapy for the treatment of intervertebral disc degeneration. However, the use of bone marrow mesenchymal stem cells as seed cells for the regeneration of fibrous rings is at risk of heterotopic ossification and teratoma at the repair site. Therefore, it is of great economic and social significance to find a new kind of seed cells for tissue engineering of annulus fibrosus for the treatment of intervertebral disc degeneration. OBJECTIVE: To isolate and purify rat annulus fibrosus-derived stem cells by adherent method combined with fibronectin differential adhesion screening method, and to observe its purification effect and biological characteristics. METHODS: Annulus fibrosus tissue was obtained from a SD rat intervertebral disc. Primary annulus fibrosus-derived stem cells were obtained by the mechanical-enzymatic digestion method. Annulus fibronectin differential adhesion method was used to purify annulus fibrosus-derived stem cells. Morphological changes and proliferation of cells were observed through a microscope. The expression levels of stem cell markers were detected by immunofluorescence technique and qPCR. The screened cells were subjected to multi-lineage cell differentiation and characteristic gene detection. RESULTS AND CONCLUSION: (1) The purified cells grew well, and most of them were angular and star-shaped multi-process cells, which had good proliferation ability. (2) Cells were positive for cell membrane surface antigens CD73, CD90 and CD105, while negative for CD45 and CD34. (3) After specific induction, cells could successfully differentiate into osteoblasts, chondroblasts and lipoblasts. (4) Collagen-I, Runx-2 after osteogenic induction, Collagen II, Sox-9 after chondrogenic induction, and PPAR -γ and LPL after lipogenic induction were highly expressed in cells, and the difference was significant compared with that before induction (P < 0.05). (5) These findings confirm that the adherent method combined with fibronectin differential adhesion method is effective enough to screen, isolate and purify rat annulus fibrosus-derived stem cells, and has good cell biological properties, good proliferation ability and multiple differentiation potential.

Objective To investigate the effect and mechanism of bone morphogenetic protein 5（BMP5) on the bio‑ logical behaviors of human liver cancer cells. Methods Normal human liver cell line L02 and human liver cancer cell lines Hep3B and Huh7 were cultured in the incubator at 37℃ with 5% CO2. The expression of BMP5 mRNA in these cells was detected by real time-quantitively PCR (RT-qPCR) . Human liver cancer cells Hep3B and Huh7 were divided into the control group (NC group), low-dose group, medium-dose group and high-dose group. Cells in the low-, medium- and high-dose groups were treated with recombinant human bone morphogenetic protein 5（rh-BMP5) at concentrations of 1, 10 and 100 ng/mL, respectively. Cell proliferation was detected by CCK-8 assay and apoptosis was detected by Annexin/PI flow cytometry. Scratch assay was used to detect cell migration. Western blotting was performed to detect the expression of proliferating cell nuclear antigen (PCNA) and key molecules in SMAD pathway (SMAD3) and its phosphorylation (p-SMAD3) . Results The expression levels of BMP5 in Hep3B and Huh7 cells significantly increased in comparison with that in L02 cells (both P<0. 05) . Compared with NC group, rh-BMP5 promoted the proliferation of Hep3B and Huh7 cells and up-regulated the expression of PCNA in the medium-dose and high-dose groups (all P<0. 05) . After the high dose (100 ng/mL) rh-BMP5 treatment, Hep3B and Huh7 cells showed decreased apoptosis rate and increased migration rate at 24 h and 48 h in comparison with those of the NC group (both P<0. 05) . The high-dose rh-BMP5 group had higher p-SMAD3 level than the NC group (P<0. 05) . Conclusions The expression of BMP5 increases in liver cancer cell lines. BMP5 promotes proliferation and migration and inhibits apoptosis of Hep3B and Huh7 cells, which may be mediated by SMAD3 phosphorylation, and thus facilitates tumor progression.

A detailed process mineralogy study was conducted on a quartz vein gold-bearing ore, and a gravity separation-gravity separation tailings flotation test and gold loss state inspection were carried out based on this study. The results showed that gold is the sole valuable element to recover with a grade of 1.78 g/t. The main gold minerals are native gold and electrum, which are disseminated in the form of encased gold, accounting for 45.33 %.The particle size is mainly concentrated at-0.037 mm, totaling 78.98 %.By using the gravity separation-gravity separation tailings flotation process, the total gold recovery rate was 94.80 %.The gold minerals lost in the flotation tailings mainly exist in the form of encased gold in vein minerals. The leaching effect of the target minerals is good, and the gold loss characteristics are in line with the results of the process mineralogy study. [ABSTRACT FROM AUTHOR]

In the task of knowledge distillation, a dual-source adaptive knowledge distillation(DSAKD)method is proposed to address the issues of feature information loss during the feature alignment process and the lack of consideration for the differences in samples in the soft label distillation method. The DSAKD method extracts more discriminative knowledge from both the feature layer and soft labels of the teacher network, which enhances the performance of the lightweight student network. An attention-based feature adaptive fusion module was proposed to integrate the intermediate layer features of the teacher network and the student network, and then the feature embedding contrastive distillation strategy was used to optimize the features of the student network. An adaptive temperature distillation strategy was also proposed, which assigned different temperature coefficients to all training samples adaptively based on the prediction confidence of the teacher network. The experimental results show that our proposed method achieves the optimal distillation effect on three benchmark datasets, significantly improving the classification performance of lightweight student networks. Specifically, compared with the best-performing method, the proposed method improves the average top-1 validation accuracy on CIFAR10, CIFAR100, and ImageNet datasets by 0.46%, 0.41%, and 0.59%, respectively.

The safety and survival benefits of abiraterone acetate and docetaxel in the treatment of patients with metastatic hormone-sensitive prostate cancer have been confirmed by randomized controlled trials and clinical studies abroad. However, real-world studies remain lacking. In this article, we review the progress of real-world studies of abiraterone acetate and docetaxel in the treatment of patients with metastatic hormone-sensitive prostate cancer and the problems faced in clinical practice against the background of differentiated real-world studies. Further research is needed to address clinically important issues, such as individualized dosing, combination dosing, and monitoring of adverse effects. [ABSTRACT FROM AUTHOR]
