Today, is the study of China as a world power, the standpoint of the humanities, review the new start of expectation. In the living environment of the city"s plan, if you want to create a place to live in the city space, not only the richness of modern physics, more important is through the real communication among citizens, enjoy the true value of life, believe that space form, can to promote the communication between people help. The purpose of this study is to search for promote interpersonal communication space form, mainly in the possibility of the third class space.

The functional role of microRNA-375 (miR-375) in the development of prostate cancer (PCa) remains controversial. Previously, we found that plasma exosomal miR-375 is significantly elevated in castration-resistant PCa (CRPC) patients compared with castration-sensitive PCa patients. Here, we aimed to determine how miR-375 modulates CRPC progression and thereafter to evaluate the therapeutic potential of human umbilical cord mesenchymal stem cell (hucMSC)-derived exosomes loaded with miR-375 antisense oligonucleotides (e-375i). We used miRNA in situ hybridization technique to evaluate miR-375 expression in PCa tissues, gain- and loss-of-function experiments to determine miR-375 function, and bioinformatic methods, dual-luciferase reporter assay, qPCR, IHC and western blotting to determine and validate the target as well as the effects of miR-375 at the molecular level. Then, e-375i complexes were assessed for their antagonizing effects against miR-375. We found that the expression of miR-375 was elevated in PCa tissues and cancer exosomes, correlating with the Gleason score. Forced expression of miR-375 enhanced the expression of EMT markers and AR but suppressed apoptosis markers, leading to enhanced proliferation, migration, invasion, and enzalutamide resistance and decreased apoptosis of PCa cells. These effects could be reversed by miR-375 silencing. Mechanistically, miR-375 directly interfered with the expression of phosphatase nonreceptor type 4 (PTPN4), which in turn stabilized phosphorylated STAT3. Application of e-375i could inhibit miR-375, upregulate PTPN4 and downregulate p-STAT3, eventually repressing the growth of PCa. Collectively, we identified a novel miR-375 target, PTPN4, that functions upstream of STAT3, and targeting miR-375 may be an alternative therapeutic for PCa, especially for CRPC with high AR levels.

Objective: Noninvasive prenatal detection of trisomy 21 (T21) has been achieved by measuring the ratio of two alleles of a single nucleotide polymorphism in circulating placenta specific 4 (PLAC4) mRNA in maternal plasma with a few assays in recent years. Our research is to explore the variations of PLAC4 mRNA expression level in maternal plasma with normal pregnancies in second trimester, which can provide pregnant women deeper insights with suitable detection period for the non-invasive prenatal detection of T21. Methods: We measured a serial plasma PLAC4 mRNA concentrations weekly from the same 25 singleton normal pregnant women. We recruited maternal plasma samples from 45 singleton pregnant women , comprising of 25 euploid pregnancies (control group; range, 17 to 21 weeks) and 20 T21 pregnancies (T21 group; range, 19 to 24 weeks). With the application of reverse transcription polymerase chain reaction, we achieved an insight of PLAC4 mRNA expression levels in maternal plasma during second trimester with euploid pregnancies. Results: Among the control group, the levels of PLAC4 mRNA expression in the gestation of 17 to 18 weeks were significantly less than those in the gestation of 18 to 21 weeks (P<0.05). The average PLAC4 mRNA concentration of the normal pregnant women was not higher than that of the T21 group (P>0.05). Conclusion: The PLAC4 mRNA showed a higher level of expression in the gestation of 18 to 21 weeks with an euploid pregnancy of pregnant women. We also found that there was no significant difference in plasma PLAC4 mRNA concentration between the normal and the T21 pregnancies in second trimester.
