Objective Prostate cancer (PCa) is one of the most prevalent cancers affecting men worldwide. However, the biological functions of circRNAs in PCa are still largely unknown. Methods Real-time PCR (RT-PCR) and immunohistochemistry were performed to characterize the circ-102004 expression in both human PCa tissues and cell lines. The apoptosis and cell cycle status of prostate immortalized cell lines that were overexpressed with circ-102004 by transfection was analyzed using flow cytometry. The scratch test and the Transwell assay were conducted to evaluate the ability of transfected cells to migrate and invade. RNA sequencing, pathway analysis, and Western blotting were performed to probe the associations of circ-102004 with the classical cancer signaling pathways after functionally evaluating circ-102004 in a xenograft tumor model. Results In the present study, circ-102004 expression was found to be significantly higher in PCa samples than in the matched normal tissues. In functional experiments, circ-102004 is shown to play an oncogenic role in PCa by stimulating cancer cell migration and invasion. Circ-102004 overexpression was also accompanied by significant alterations in many signaling pathways, such as ERK, JNK, and Hedgehog, which are known to cause different types of cancers. Conclusions Circ-102004 is a potential oncogenic gene that regulates the development and progression of PCa. This study provides a scientific basis for targeting circ-102004 for either diagnosis or therapy.

The aim of the present study was to investigate the candidate genes and pathways associated with benign prostatic hyperplasia (BPH) and diabetes. In vitro experiments were performed using normal prostatic epithelial RWPE-1 and HPr-1 cells. The cell lines were treated with a high-glucose solution and MTS and bromodeoxyuridine assays were used to assess cell viability. Transcriptome sequencing was used to screen the candidate genes. The expression of candidate genes was further verified by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blotting. A meiotic recombination 11 (MRE11) overexpression vector was designed and transfected into RWPE-1 cells to verify the function of MRE11. A streptozotocin-induced diabetic rat model was established and rat MRE11 levels were determined by RT-qPCR and immunohistochemical staining. High concentrations of glucose resulted in RWPE-1 and HPr-1 cells with high viability. Transcriptome sequencing revealed that MRE11 was downregulated when RWPE-1 cells were exposed to high-glucose conditions. When MRE11 was overexpressed, cell viability decreased and cell apoptosis was induced under high-glucose conditions. Prostatic tissues from rats were collected and assessed; MRE11 expression was observed to be decreased, which was consistent with the in vitro cell experiments. BPH may be associated with diabetes, as MRE11 expression in prostatic cells was decreased when exposed to high-glucose conditions. Therefore, MRE11 may have potential as a biomarker for the early diagnosis of BPH and diabetes.

Hypericin (HY) is a promising photosensitizer (PS) for use in photodynamic therapy (PDT). Port-wine stains (PWSs) are congenital superficial dermal capillary malformations. In this study, we evaluated the photocytotoxic effects of HY for PDT in human vascular endothelial cells and a chicken cockscomb model. HY significantly inhibited the growth of human umbilical vein endothelial cells (HUVECs), as determined by colorimetric assays and morphological observation, and flow cytometry assays indicated induction of apoptosis and collapse of the mitochondrial membrane potential. In addition, HY more effectively inhibited growth of and induced apoptosis in HUVECs compared with hematoporphyrin (HP). Further experiments performed in a Roman chicken cockscomb model also showed a clear photocytotoxic effect on the cockscomb dermal capillary upon intravenous injection of HY. This effect may be due to the role of HY in the induction of apoptosis. Transmission electron microscopical analysis showed mitochondrial morphological changes such as incomplete ridges and swelling, and immunohistochemical assays showed an increase in the release of cytochrome c. In conclusion, HY exhibited a greater photocytotoxic activity than did HP toward the growth of endothelial cells and may thus represent a potent PS for PWS PDT.

This study reports on the performance of sodium alginate (SA)/poly(vinyl alcohol) (PVA)/moxifloxacin hydrochloride (MH) nanofibrous membranes (NFM) capable of providing antibacterial agent delivery for wound-dressing applications. The aim of this work was to prepare antibacterial NFM with good permeability properties by employing PVA and SA as carriers. A group of 12% PVA/2% SA solutions blended in various ratios (8:2, 7:3, 6:4, 5:5 and 4:6, v/v) and containing 0.5, 1, 2 or 4 wt% MH were studied for electrospinning into nanoscale fibermats. The optimum ratio found to form smooth fibers with uniform fibrous features was 6:4. The drug release behavior of the electrospun, the antibacterial effects on Pseudomonas aeruginosa and Staphylococcus aureus and the animal wound dressing capabilities were also investigated. As much as 80% of the MH was released from the electrospun after 10 h of incubation at 37 °C. In addition, the NFM with 0.5 MH exhibited less activity, whereas those with higher concentrations of MH exhibited greater antibacterial effect. Furthermore, the MH-loaded electrospun accelerated the rate of wound dressing compared to other groups. The results of the in vitro and in vivo experiments suggest that MH/PVA/SA nanofibers might be an interesting bioactive wound dressing for clinical applications.

Privilege refers to a psychological feel right to preferential treatment, being exempt stable social responsibility and universal subjective belief or perception, in different areas can be expressed as a sense of academic privilege, the consumer a sense of privilege, the privilege workplace flu. Psychological privilege enables individuals to become narcissistic, induced interpersonal conflict, selfishness and aggression and so on. The main factors affecting the psychological privilege of individual factors contextual factors have life experience, rearing, attachment type, socioeconomic status, and other environmental organizations and self-compassion, subjective construct, egalitarian values, and so on. Future studies should further explore the psychological privileges concept and structure, expand its research methods, longitudinal studies and strengthen indigenous research and to further explore the psychological factors that may affect the privileges of the privileged and psychological ways to avoid negative consequences (or reduced). As an important element of people's social life, a psychological sense of privilege determines the individual's attitude and implementation efficiency towards social rules, corporate requirements, and work. As a result, people with high levels of psychological privilege are more resistant to being bound by rules and more difficult to manage. Individuals with low levels of psychological privilege are more likely to follow orders. At the same time, from the perspective of identity theory resources and self-regulation and another theoretical perspective of workplace, psychological privilege research is summarized and reviewed.
