Objective To evaluate the effects of Yiqi Huayu Jiedu Decoction combined with chemotherapy on disease-free survival rate and disease-free survival(DFS)of patients with stage Ⅱ and Ⅲ postoperative gastric cancer.Methods Totally 102 patients with stage Ⅱ and Ⅲ postoperative gastric cancer treated by Affiliated Hospital of Nanjing University of Chinese Medicine and Nanjing Drum Tower Hospital were selected.The patients were divided into control group(52 cases)and test group(50 cases)with block random method.The control group received conventional postoperative adjuvant chemotherapy for 4-6 cycles.The test group was treated with Chinese materia medica for 6 months on the basis of chemotherapy.Continue follow-up until the patients had recurrence,metastasis or death.DFS was analyzed by Kaplan-Meier method,and the average DFS of the two groups was estimated.Log Rank test was used to test the significance of differences in survival distribution between groups.Univariate and multivariate analyses of variables affecting prognosis were conducted using the Cox regression model.Adverse reactions of both groups were monitored.Results The recurrence and metastasis rate of the test group was 12.0%(6/50),while that of the control group was 34.6%(18/52),which was lower in the test group than in the control group(P<0.05).The 1-year and 2-year DFS rates and DFS of the control group were 86.5%,72.2%and 25.8 months respectively,while those of the test group were 95.6%,84.1%and 33.9 months respectively,with statistical significance(P=0.012).Cox-regression analysis suggested:The independent factors influencing the disease-free survival time of patients with gastric cancer were the test group(P=0.022),surgical methods of subtotal gastrectomy(P=0.038)and clinical stages Ⅱ(P=0.040).No adverse reactions related to Chinese materia medica were reported in the two groups.Conclusion Yiqi Huayu Jiedu Decoction combined with chemotherapy can improve the 1-year and 2-year DFS rate,prolong DFS,reduce the recurrence and metastasis rate,and improve the prognosis.

Objective: Self-determination theory (SDT) deems that people have three causality orientations: autonomy orientation, control orientation, and impersonal orientation. Previous studies suggested that lower autonomy orientation or higher control and impersonal orientations may be associated with more addictive behaviors. Our study aimed to investigate if these associations exist in Internet gaming disorder (IGD), and if sensation seeking, anxiety, and depression could influence the associations between causality orientations and IGD symptoms. Methods: A total of 1,400 college students completed the Internet Gaming Disorder Scale, General Causality Orientation Scale, Brief Sensation Seeking Scale, Generalized Anxiety Disorder Scale, and Patient Health Questionnaire. Correlation, multiple linear regressions, structural equation model (SEM) analyses, and moderation analyses were conducted to explore the associations. Results: The control and impersonal orientations were positively associated with IGD symptoms, while the autonomy orientation was negatively associated with them. Moreover, SEM analyses showed that the autonomy-IGD relationship was totally mediated by anxiety and depression, the impersonal-IGD relationship was partially mediated by anxiety, and the control-IGD relationship was partially mediated by depression. Finally, the effects of causality orientations on IGD were moderated by sensation seeking. Conclusion Overall, autonomy orientation is linked to fewer gaming problems, whereas control and impersonal orientations are associated with more gaming problems. Moreover, the relationships between causality orientations and IGD symptoms are mediated by anxiety and depression and moderated by sensation seeking. Our findings inform theory on the motivations of gaming behaviors and may shed light on the prevention and intervention of IGD from the perspective of SDT.

Cerium oxide nanoparticles (CeO₂ NPs), as the oxides of the most abundant elements in rare earths, have been widely used in biomedical and industrial production and other fields that are closely related to human life. China is a large country in resources and production of rare earth, and the impact of CeO₂ NPs on human health has been increasingly concerned. In response to the possible health risks of CeO₂ NPs, researchers begin to focus on their toxic effects on living organisms, especially on the reproductive system. The male reproductive system is not only responsible for producing sperm and regulating the secretion of testosterone, but also plays a key role in maintaining male sexual characters and function. Any adverse effects on the male reproductive system may lead to reduced fertility and reproductive dysfunction. Some studies have shown that long-term exposure to CeO₂ NPs may lead to gonadal damage, sex hormone disorders, and other problems in male animals. Therefore, an in-depth study of the potential effects of CeO₂ NPs on the male reproductive system is of great scientific significance and practical value. In this study, we reviewed the male reproductive toxicity of CeO₂ NPs in terms of spermatogenic cells, spermatozoa structure, blood-testis barrier, hypothalamic-pituitary-gonadal axis, and functional changes in epididymis, and analyzed the effects of the size and shape of physicochemical parameters of CeO₂ NPs on the toxicity to male reproductive system. The findings will provide a theoretical basis and scientific evidence for the rational use of CeO₂ NPs.

Objective To investigate the role of miRNAs in maternal amniotic fluid exosomes in development of isolated ventriculomegaly(VM)in fetuses.Methods Amniotic fluid samples were collected from 9 cases of moderate isolated VM and 8 normal control cases to extract exosomal miRNA,and miRNA sequencing technique was used to identify differentially expressed miRNAs between the two groups.Three miRNAs with significant differential expression between the two groups,whose high expression was associated with VM,were selected for verification with RT-qPCR.Dual luciferase reporter assays were used to verify the regulatory effect of miR-122-5p on its predicted target genes AKT3 and CCDC88C.Gene ontology(GO)and KEGG pathway analyses were performed to explore the possible roles of the top 40 significant differential miRNAs in the pathophysiology of VM.Results We identified a total of 272 differentially expressed miRNAs in VM cases,including 43 up-regulated and 229 down-regulated miRNAs.The target genes of these differential miRNAs were associated with DNA and transcription factor binding,transmembrane transporter and nucleic acid binding transcription factor activity,and cell developmental process.These miRNAs were mostly enriched in the MAPK,cGMP-PKG and Wnt signaling pathways.Verification with RT-qPCR showed that miR-122-5p expression level was significantly lower in VM group than in the control group(P<0.05),which was consistent with miRNA sequencing results;let-7b-5p expression level was significantly lower in VM group,which was contrary to miRNA sequencing result.Dual luciferase reporter assays showed that miR-122-5p was not capable of regulating AKT3 or CCDC88C expressions.Conclusions The highly abundant differentially expressed miRNAs in maternal amniotic fluid exosomes play important roles in the occurrence of fetal VM possibly by regulating the MAPK,PI3K-Akt,Wnt and cGMP-PKG signaling pathways.
