Background Glioma has the chief type of primary brain tumors worldwide. The glioma may be controlled by regulatorsincluding some lncRNAs, miRNAs, and proteins. Objective Our study aims to discover the underlying mechanism for lncPCAT19/miR-142-5p/MELK axis in gliomaprogression. Methods The clinical samples were from patients with gliomas in our Hospital. Hematoxylin–eosin staining (H&E) wasapplied to determine the clinical pathological changes. Real time PCR was performed to measure the levels of lncPCAT19,miR-142-5p, MELK, and expression of other genes. Western blot was conducted to detect the protein level of MELK. RIPassay was performed to analyze the interaction between lncPCAT19 and miR-142-5p, and dual-luciferase reporter assay wasused to determine the binding site between lncPCAT19 and miR-142-5p. CCK-8, colony formation assay, flow cytometry,and trans-well assay were carried out to confirm cell proliferation, colony formation, apoptosis, and invasion, respectively. Results LncPCAT19 was increased in cancer tissues. Then, lncPCAT19 could interact with and down-regulate miR-142-5p. Knockdown of lncPCAT19 distinctly inhibited tumor growth in vivo. Interfering lncPCAT19/overexpression of miR-142-5pdecreased glioma cell proliferation, colony formation and invasion, and promoted cell apoptosis by down-regulating expressionof Cyclin B1, CDK2, N-cadherin, Bcl-2, and by up-regulating expression of Bax and E-cadherin. Moreover, overexpressionof lncPCAT19 overturned tumor-suppressing role of miR-142-5p in cells. Additionally, lncPCAT19 and miR-142-5psynergistically regulated expression of MELK. In conclusion, lncPCAT19 enhanced glioma development via increasingMELK by performing as a sponge of miR-142-5p. Conclusions LncPCAT19 promotes glioma progression by sponging miR-142-5p to upregulate MELK levels. Thus, lncPCAT19/miR-142-5p/MELK signaling would be a potential target for glioma treatment.

Heat stress (HS) may induce immunosuppression as well as inhibit the proliferation of lymphocytes. This study evaluated the effects on immune function of our prescription on splenic lymphocytes under HS as well as its compatibility. The effects of four herbal extracts from Agastache rugosa, Atractylodes lancea, Cortex Phellodendri, and Gypsum Fibrosum on heat treated splenic lymphocytes were investigated and the compatibility of the prescription was also explored by using the Taguchi method. This study revealed changes in proliferation by traditional Chinese medicines of splenic lymphocytes after HS. Proliferation in the HS group was significantly lower than the control group. Under HS, the effects of higher concentrations of Agastache rugosa (100 and 200 μg/mL), Atractylodes lancea (100 and 200 μg/mL), Cortex Phellodendri (50 and 100 μg/mL) and Gypsum Fibrosum (100 and 200 μg/mL) caused a significant increase on ConA/LPS-induced proliferation of lymphocytes than lower concentrations. We, therefore, conclude that the prescription of traditional Chinese medicines may recover splenic lymphocytes from the immunosuppression induced by HS. The Taguchi design, which allows rapid and high efficiency for the selection of the best conditions for our prescription on HS-treated splenic lymphocytes, demonstrated that Agastache rugosa (200 μg/mL), Atractylodes lancea (200 μg/mL), Cortex Phellodendri (100 μg/mL) and Gypsum Fibrosum (100 μg/mL)were the optimal conditions for the prescription. The validation experiment confirmed that our composition in optimum extraction conditions enhanced effects on ConA or LPS-stimulated lymphocytes under HS. The results showed that the Taguchi optimization approach is a suitable method for optimization of the composition of prescription.

Objective: Hypoactivity in the reward system among patients with attention deficit hyperactivity disorder (ADHD) is a well-known phenomenon. Whether the activity in the reward pathway is related to harm avoidance, such as in sensitivity to punishment, is unclear. Evidence regarding the potential difference between ADHD patients and controls in terms of this association is scarce. Methods: Event-related functional magnetic resonance imaging was conducted on subjects performing the Iowa gambling test. Fourteen adults with ADHD and 14 controls were enrolled in the study. Results: Harm avoidance was found to be positively correlated with the activities of the bilateral orbitofrontal cortex and right insula in individuals with ADHD. A group difference was also confirmed. Conclusion: Understanding the roles of harm avoidance and brain activation during risk tasks is important.

In this study, we used RNA sequencing (RNA-seq) to analyze and compare bulk cell samples from wild-type (WT) dermal mesenchymal stem cells (DMSCs) (n = 3) and Prx II knockout DMSCs (n = 3). The purpose of the study was to elucidate the role of Prx II on allogeneic immune rejection of transplanted DMSCs. The results revealed differential expression of 472 genes (176 up-regulated and 296 down-regulated; p ≤ 0.05) between the PrxII+/+ (WT) and PrxII−/− sample groups. When highly regulated genes were categorized according to the Gene Ontology (GO) molecular function classification and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, the PrxII−/− samples showed a robust downward trend in allograft rejection. The study identified 43 all immunologically rejected differentially expressed genes, of which 41 showed lower expression in the PrxII−/− vs. PrxII+/+ (WT) samples. These findings suggest that Prx II gene knockout may down-regulate the allograft rejection that occurs during DMSCs transplantation and improve the survival rate of DMSCs in the host. This study provides a new perspective on the clinical treatment of stem cell transplantation.

The purpose of this study was to understand the effect of WeChat relational benefits on customer satisfaction and purchase intention. Due to the rapid development in the technological field, the use of WeChat has expanded drastically in recent years. In visual arts industry, WeChat business occupies a significant proportion of emerging industries. The recruited participants that were recruited via an online survey website were 335 (www.sojump.com). SPSS 22.0 statistical system was used to analyze the descriptive statistics, reliability, and validity. This study conceptualizes the positive relationship among relational benefits, customer satisfaction, and purchase intention of visual arts products. The findings indicated that WeChat users’ relational benefits can be categorized into two distinct benefit types: confidence, and social benefits. The more relational benefits WeChat users perceived, the higher the level of satisfaction. In contrast, the positive influence of customer satisfaction on purchase intention is weaker in consumers with a higher level of perceived risk. The results of this study will help WeChat business to retain its customers, thus, gaining a long-term value for visual arts industry. Theoretical and managerial implication for WeChat business are provided.

In the current economic downturn, it is easy for consumers to be emotional and regret their fashion product purchases. The purpose of this paper was to understand the effect of customer regret on the dissatisfaction and repurchase intention of fashion consumers in China, which is the world's largest fashion trading country. A total of 275 participants were recruited from a Chinese online survey system (www.sojump.com). The SPSS 22.0 statistical package was used for various data analyses. This study conceptualized the positive relationship between customer regret and dissatisfaction and the negative relationship between dissatisfaction and the repurchase intention of fashion goods. The findings indicated that customer regret could be categorized into two distinct types, chosen and forgone regrets. Chosen regret had a greater effect than forgone regret on dissatisfaction. The negative influence of dissatisfaction on repurchase intention was weak in consumers with a high level of regret-solving effort. The results of this study will help fashion businesses retain their customers, thus gaining long-term and repurchase economic value for the fashion industry.
