Implementation of dynamic processes of innovative transformations in the social sphere of many countries of the world is a guarantee for an effective management of their socio-economic systems. ...Today, the People’s Republic of China (PRC) is trying to find its own approach to the effective development of the social infrastructure of the territories, the problem of which is actualized in the context of large-scale socio-economic reforms, and the possibility of a solution is supported by the significant growth of the innovative potential of the PRC. It is noted that maintenance at the achieved level and further socio-economic development of the state are not possible without regular implementation of innovations. China is one of the world’s technological and scientific leaders, adapting quickly and creating its own innovations. However, the development of the social sector requires separate innovative initiatives and projects. It is determined that social innovation has been promoted as China’s national development strategy since the mid-2010s. New ideas, patterns of organizational behavior, and political agendas have been transformed into social innovations. These events create a climate that promotes social innovation as a general conception. The views of scientists of the People’s Republic of China regarding the harmonious social development of Chinese society were considered, including the implementation of the priority strategy of education; improving the health care system; active implementation of employment policy; creation of a fair distribution system; fair social guarantees; coordinated development of regions. The steps for implementing China’s socio-economic breakthrough strategy are highlighted: first, increasing the share of the market economy and reducing the level of support for the state-owned enterprises; secondly, stimulation of the domestic market and consumption; third, improving social protection, which will help solve the demographic problem; fourth, invest in the development of less polluting industries, gradually reduce the number of thermal power plants, switch to alternative energy sources; fifthly, the fight against corruption and strengthening the rule of law are of fundamental importance.
Culture is the embodiment of a country's social style, as a country’s spiritual embodiment, culture can not only bring economic benefits to a country, but also can show a country’s social style, the ...role of culture can not be underestimated. Therefore, this paper is mainly based on the “Internet plus” background of the music and cultural industry innovation model to explore. Mainly for two aspects of research and discussion, the first is the current music and cultural industry facing the development of challenges; the second is the current music and cultural industry innovation model and innovative thinking. At the same time, I hope that enterprises can play a certain role in innovation inspiration. It is hoped that this paper can provide a little reference for the relevant research, so as to lay a solid foundation for the development of the relevant music and cultural industry.
There are remarkable disparities among patients of different races with prostate cancer; however, the mechanism underlying this difference remains unclear. Here, we present a comprehensive landscape ...of the transcriptome profiles of 14 primary prostate cancers and their paired normal counterparts from the Chinese population using RNA-seq, revealing tremendous diversity across prostate cancer transcriptomes with respect to gene fusions, long noncoding RNAs （long ncRNA）, alternative splicing and somatic mutations. Three of the 14 tumors （21.4%） harbored a TM- PRSS2-ERG fusion, and the low prevalence of this fusion in Chinese patients was further confirmed in an additional tumor set （10/54=18.5%）. Notably, two novel gene fusions, CTAGE5-KHDRBS3 （20/54=37%） and USP9Y-TTTY15 （19/54=35.2%）, occurred frequently in our patient cohort. Further systematic transcriptional profiling identified nu- merous long ncRNAs that were differentially expressed in the tumors. An analysis of the correlation between expres- sion of long ncRNA and genes suggested that long ncRNAs may have functions beyond transcriptional regulation. This study yielded new insights into the pathogenesis of prostate cancer in the Chinese population.

Bright and efficient blue emission is key to further development of metal halide perovskite light-emitting diodes. Although modifying bromide/chloride composition is straightforward to achieve blue ...emission, practical implementation of this strategy has been challenging due to poor colour stability and severe photoluminescence quenching. Both detrimental effects become increasingly prominent in perovskites with the high chloride content needed to produce blue emission. Here, we solve these critical challenges in mixed halide perovskites and demonstrate spectrally stable blue perovskite light-emitting diodes over a wide range of emission wavelengths from 490 to 451 nanometres. The emission colour is directly tuned by modifying the halide composition. Particularly, our blue and deep-blue light-emitting diodes based on three-dimensional perovskites show high EQE values of 11.0% and 5.5% with emission peaks at 477 and 467 nm, respectively. These achievements are enabled by a vapour-assisted crystallization technique, which largely mitigates local compositional heterogeneity and ion migration.
A major efficiency limit for solution-processed perovskite optoelectronic devices, for example light-emitting diodes, is trap-mediated non-radiative losses. Defect passivation using organic molecules ...has been identified as an attractive approach to tackle this issue. However, implementation of this approach has been hindered by a lack of deep understanding of how the molecular structures influence the effectiveness of passivation. We show that the so far largely ignored hydrogen bonds play a critical role in affecting the passivation. By weakening the hydrogen bonding between the passivating functional moieties and the organic cation featuring in the perovskite, we significantly enhance the interaction with defect sites and minimize non-radiative recombination losses. Consequently, we achieve exceptionally high-performance near-infrared perovskite light-emitting diodes with a record external quantum efficiency of 21.6%. In addition, our passivated perovskite light-emitting diodes maintain a high external quantum efficiency of 20.1% and a wall-plug efficiency of 11.0% at a high current density of 200 mA cm−2, making them more attractive than the most efficient organic and quantum-dot light-emitting diodes at high excitations.Improved understanding of passivation leads to near-infrared perovskite light-emitting diodes with 21.6% external quantum efficiency.
Purpose To understand the role of MALAT-1 in prostate cancer we evaluated its expression in prostate cancer tissues and cell lines. We also studied the therapeutic effects of MALAT-1 silencing on ...castration resistant prostate cancer cells in vitro and in vivo. Materials and Methods Quantitative reverse transcriptase-polymerase chain reaction was used to detect MALAT-1 expression in prostate cancer tissues and cell lines. siRNA against MALAT-1 was designed and the silencing effect was examined by quantitative reverse transcriptase-polymerase chain reaction. The biological effects of MALAT-1 siRNA on cells were investigated by examining cell proliferation using a cell counting kit and cell colony assays as well as cell migration by in vitro scratch assay, cell invasion by Transwell® invasion assay and cell cycle by flow cytometry. We further investigated the effect of therapeutic siRNA targeting MALAT-1 on castration resistant prostate cancer in vivo. Results MALAT-1 was up-regulated in human prostate cancer tissues and cell lines. Higher MALAT-1 expression correlated with high Gleason score, prostate specific antigen, tumor stage and castration resistant prostate cancer. MALAT-1 down-regulation by siRNA inhibited prostate cancer cell growth, invasion and migration, and induced castration resistant prostate cancer cell cycle arrest in the G0/G1 phases. Importantly, intratumor delivery of therapeutic siRNA targeting MALAT-1 elicited delayed tumor growth and reduced metastasis of prostate cancer xenografts in castrated male nude mice, followed by the concomitant prolongation of survival of tumor bearing mice. Conclusions MALAT-1 may be needed to maintain prostate tumorigenicity and it is involved in prostate cancer progression. Thus, MALAT-1 may serve as a potential therapeutic target for castration resistant prostate cancer.
Extracellular communication within the tumor microenvironment plays a critical role in tumor progression. Although exosomes can package into long non-coding RNAs (lncRNAs) to mediate extracellular ...communication, the role of exosomal lncRNA PTENP1 in bladder cancer (BC) remains unclear.
We detected PTENP1 expression between patients with BC and healthy controls; the expression occurred in tissues and exosomes from plasma. We assessed the diagnostic accuracy by the receiver operating characteristic curve (ROC) and the area under curve (AUC). Cell phenotypes and animal experiments were performed to determine the effect of exosomal PTENP1.
PTENP1 was significantly reduced in BC tissues and in exosomes from plasma of patients with BC (P < 0.05). We found that PTENP1 was mainly wrapped by exosomes. Exosomal PTENP1 could distinguish patients with BC from healthy controls (AUC = 0.743; 95% confidence interval (CI) = 0.645-0.840). Normal cells secreted exosomal PTENP1 and transmitted it to BC cells, thus inhibiting the biological malignant behavior of BC cells by increasing cell apoptosis and reducing the ability to invade and migrate (P < 0.05). Exosomal PTENP1 could suppress tumor growth in vivo. Furthermore, exosomal PTENP1 mediated the expression of PTEN by competitively binding to microRNA-17.
Exosomal PTENP1 is a promising novel biomarker that can be used for the clinical detection of BC. Exosomes derived from normal cells transfer PTENP1 to BC cells, which reduce the progression of BC both in vitro and in vivo and suggest that exosomal PTENP1 participates in normal-cell-to-bladder-cell communication during the carcinogenesis of BC.

Lipid production in the industrial microalga Nannochloropsis gaditana exceeds that of model algal species and can be maximized by nutrient starvation in batch culture. However, starvation halts ...growth, thereby decreasing productivity. Efforts to engineer N. gaditana strains that can accumulate biomass and overproduce lipids have previously met with little success. We identified 20 transcription factors as putative negative regulators of lipid production by using RNA-seq analysis of N. gaditana during nitrogen deprivation. Application of a CRISPR-Cas9 reverse-genetics pipeline enabled insertional mutagenesis of 18 of these 20 transcription factors. Knocking out a homolog of fungal Zn(II)

Abstract Objective Emerging evidences implicate long noncoding RNAs (lncRNAs) are deregulated in cancer development. The purpose of the current study is to investigate the role of new lncRNA, named ...PlncRNA-1, in prostate cancer (CaP) pathogenesis. Materials and methods In this study, real-time q-PCR was used to demonstrate the expression of PlncRNA-1 in 16 pairs CaP tissues and matched normal tissues, 14 pairs CaP tissues and BPH tissues, 4 CaP cell lines, including LNCaP, LNCaP-AI, PC3, and C4-2, and 2 normal prostate epithelial cell lines RWPE-1 and PWR-1E. After PlncRNA-1 was suppressed by siRNA in LNCaP and LNCaP-AI cell lines, cell proliferation and apoptosis were assessed using CCK-8 and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL). After PlncRNA-1 and AR was suppressed by siRNA in LNCaP and LNCaP-AI cell lines, real-time q-PCR and Western blotting were used to measure reciprocal regulation of PlncRNA-1 and AR. Results We showed that expression PlncRNA-1, was significantly higher in CaP cells relative to normal prostate epithelial cells, as well as higher in human CaPs compared with normal tissues and benign prostatic hyperplasia (BPH). Silencing of PlncRNA-1 significantly reduced cell proliferation and induced apoptosis in CaP cell lines LNCaP and LNCaP-AI. Mechanistically, PlncRNA-1 suppression by siRNA resulted in a decrease of androgen receptor (AR) mRNA, protein and AR downstream target. Of note, blockade of AR signaling with siRNA also resulted in a suppression of PlncRNA-1 expression in CaP cell lines. Conclusions Our study suggests reciprocal regulation of PlncRNA-1 and androgen receptor contribute to CaP pathogenesis and that PlncRNA-1 is a potential therapy target.
