Non-coding RNAs (ncRNAs) are a large class of RNA molecules that do not encode proteins, regulate gene expressions multifacetedly, and influence the metabolism, proliferation, differentiation and apoptosis of cells as well as the occurrence and progression of tumors. Some of the ncRNAs act as cancer genes, such as miR-19a, miR-125b, miR-616, miR-7, miR-221, MALAT-1, and PRNCR1, which are upregulated in castration-resistant prostate cancer (CRPC) tissues or cell lines, and promote the development and progression of CRPC, some act as tumor suppressor genes, including miR-185, miR-342, miR-15, miR-16, and miR-146, which are downregulated in CRPC tissues or cell lines and inhibit or delay the occurrence of CRPC, and still others, such as miR-7, miR-19a, miR-125b, miR-221, and MALAT-1, are differentially expressed in the serum or tissue and can be used as potential biomarkers for the early diagnosis and prognosis of CRPC. This article presents an overview on the roles of ncRNAs in the occurrence, progression, diagnosis, and prognosis of CRPC and advances in their studies.

Objective: To observe the influence of rapamycin on the differentiation and proliferation of CD4+ CD25+ Treg cells, so as to lay a foundation for further studying its role in inducing immune tolerance. Methods: The spleens were taken from C57BL/6 mice under sterile condition and the mononuclear cells were isolated. CD4+ T cells were isolated by immunomagnetic beads (negative) and were divide into normal control group, rapamycin (0.1 μmol/L, for 7 days) group and cyclosporine (0.5 μmol/L, for 7 days) group. Flow cytometry was used to determine the proportions of CD4 +CD25+ Treg cells, and RT-PCR was used to examine the expression of Foxp3 mRNA. Results: Compared with the control group, the proportion of CD4+CD25+ Treg cells in the CD4+ T cells was significantly decreased ([7.42±0.82]% vs [3.72±0.74]%, P<0.01) in the cyclosporine group and was significantly increased ([7.42±0.82]% vs [11.47±1.08]%, P<0.01) in the rapamycin group. Expression of Foxp3 mRNA in rapamycin group was significantly higher than that in the other 2 groups (P<0.01), expression of Foxp3 mRNA in the cyclosporine group was significantly lower than that in the control group (P<0.05). Conclusion: Rapamycin can promote the proliferation and growth of CD4 + CD25+ Foxp3+ Treg cells in vitro, and facilitate the development of immune tolerance. It has a different immune suppression mechanism with cyclosporine A.

Objective Previous study found that ifbroblast growth factor-2(FGF2) expression was at a low level in bone marrow of children with aplastic anemia. In this study, we established a bone marrow failure animal model to investigate whether FGF2 is involved in bone marrow failure. Methods BALB/c mice were irradiated by 5.0 Gy ray, and then infused with 1×106 lymphocytes from allogeneic mice lymph node. Peripheral blood cells and bone marrow mononuclear cells counting and bone marrow pathology were done. FGF2 protein in bone marrow mononuclear cells was measured by ELISA. Results Compared with the control group, the counting of hemoglobin, white blood cell, platelet and bone marrow mononuclear cell in aplastic anemia mouse model were signiifcantly deceased (P<0.05). Moreover, FGF2 expression in aplastic anemia mouse model were signiifcantly reduced (P<0.05). Conclusions 5.0 Gy ray irradiation and then 1×106 lymphocyte infusion in mice can induce bone marrow failure similar to the features of aplastic anemia. The low expression of FGF2 in bone marrow of aplastic anemia patients may play an important role in the pathogenesis of aplastic anemia.

AIM: To investigate the effect of cyclophosphamide(CTX) on proliferation and apoptosis of mesangial cells(GMC) of rat in vitro. METHODS: GMC proliferation was detected by MTT method, GMC apoptosis was examined by inverted microscopy for phase-contract and fluoroscopy and flow cytometry analysis. The levels of Fas and Bcl-2 were also detected by immunohistology. RESULTS: The proliferation of GMC were inhibited by CTX, methylprednisolone(MP), low molecular weight heparin(LMWH). Apoptosis of GMC was induced by CTX, the apoptosis rate of GMC was 8.2%, and the Fas level was increased. CONCLUSION: CTX could inhibit proliferation and induce apoptosis of GMC possibly by enhancing the Fas level.

OBJECTIVE: To study the lactagogue effect of Rutong granule on rat with postpartum hypogalactia. METHODS: Female rats which had kittening behavior within 24 h were selected to induce rat model by perfusing bromocriptinum. Meanwhile, model rats were given Rutong granule via i.g. gtt. Milk yield of female rats and body weight of young rats were determined everyday from the second day. Rats were sacrificed on the 8th day. The level of PRL and histological change of breast were observed. RESULTS: Rutong granule can increase the serum PRL level gradually to promote the increase of acinar number and dilatation of gland ducts. Rutong granules can also increase the milk yield of female rats and weight of young rats. CONCLUSION: Rutong granule can promote secretion of milk by means of increase of PRL level and expediting of secretion channels.
