Stress urinary incontinence is one of the most common diseases in urinary system.At present,the major methods for treating stress urinary incontinence include medication,physico-behavior therapy and operation.However,for various reasons,the current methods do not yield satisfactory results.As a newly emerging technique,tissue engineering provides a new concept and method to treat stress urinary incontinence.The application of tissue engineering in the treatment of stress urinary incontinence is reviewed in this article.

Objective To explore the method of culture of rat adipose-derived stem cells(ADSCs) and differentiation induction into myoblasts. Methods Adipose tissues were obtained from SD rats,and were isolated by enzyme digestion and cultured into ADSCs.The expression of surface antigen CD90,CD105 and CD34 was detected by immunofluorescence and flow cytometry.ADSCs of the second passage with logarithmic growth were obtained,and culture media containing 5-azacytidine(5-aza) and basic culture media were employed for cells in induction group and control group,respectively.The induction lasted for 7 d,14 d,21 d,28 d and 35 d,respectively.Cell growth and cell morphology were observed by inverted phase contrast microscope,and immunofluorescence and flow cytometry were utilized to detect the expression of myoblast specific antigens desmin and myosin. Results ADSCs were successfully isolated and cultured,and were identified to be stem cells.On the 28th day of induction,cells in induction group displayed "swirl" morpholgy,and multinucleation was observed.It was revealed by immunofluorescence and flow cytometry that the highest expression rates of desmin and myosin were 52.57% and 50.04%,respectively on the 28th day of induction,while there was no expression before induction and in control group. Conclusion ADSCs can be isolated and cultured from rat adipose tissues,and can further differentiate into myoblasts after induction by culture media with 5-aza.The expression of myoblast specific antigen is the highest on the 28th day of induction.

To set standards for histomorphological studies on Lysimachia fortunei, an efficacious and widely applied folk medicine in this study, in order to develop its resources. Its species were identified by observing plant morphology and herbs appearance characters, preparing slices with routine methods and defining structural characters. According to the results of morphologic observation, leaves, stamen and pistil of this plant were different from the descriptions in Flora of China. The whole herb can be used in medicines, mainly including rhizomes, stems and leaves. According to the findings in the first study on microscopic structures, its rhizomes, stems and leaves were characteristic and worth identifying. The transaction tissue structures of rhizomes and stems were under developed and contained endodermis, secretory structures; Stems had sclerenchymata of different shapes of sclereids; Leaves were bifacial and had vascular bundles under midribs, which were surrounded by parenchymal sheathes. On the surface of leaves, stomata, glandular hairs and keratin lines were morphologically different in upper and lower epidermis. The herbal power had glandular hairs, sclereids and vessels. In conclusion, herbs of L. fortunei can be identified by the above histomorphological characteristics, which lays a foundation for further development and application of L. fortunei.

Emerging evidence has indicated that circular RNAs (circRNAs) play pivotal roles in the regulation of cellular processes and are found to be aberrantly expressed in a variety of tumors.However,the clinical role of circRNAs in bladder cancer (BC) and the molecular mechanisms have yet to be fully understood.In this study,the clinical specimens were obtained and the expression level of a circRNA BCRC4 was detected by real-time PCR in both BC tissues and cell line.The circular RNA over-expression plasmid was constructed and transfected into BC cells and related cell line.The cell cycles and apoptosis were observed using inverted microscope and flow cytometry.Western blotting was used to compare the relative protein expression of groups with different treatments.It was found that circRNA BCRC4 expression was lower in BC tissues than in adjacent normal tissues.Furthermore,consequences of fomed-expression of BCRC4 promoted apoptosis and inhibited viability of T24T and UMUC3 cells,and up-regulated BCRC4-inereased miR-101 level,which suppressed EZH2 expression in both RNA and protein levels.In addition,gambogic acid (GA) is a promising natural anticancer compound for BC therapy,and GA treatment increased the BCRC4 expression in T24T and UMUC3 cells in a dose-dependent manner.Altogether,our findings suggest that BCRC4 functions as a tumor suppressor in BC,and mediates anticancer function,at least in part,by up-regulating the expression of miR-101.Targeting this newly identified circRNA may help us develop a novel strategy for treating human BC.

Isolated alkaloids from Coptis chinensis Franch. The compounds were identified as berberine, columbamine, groenlandicine, jatrorrhizine, magnoflorine, corydaldine and ferulic acid methylester. Then measured their bitter degree based on the electronic tongue and evaluated the antibacterial. The results based on the Electronic Tongue showed that berberine, columbamine, groenlandicine and jatrorrhizine have higher bitter degree than magnoflorine and corydaldine. And they also appeared better antibacterial activity on E. coli and S. aureus. The correlation coefficients between bitter degree and the two bacteria antibacterial activity were 0.983 and 0.911. So there was close relationship between the bitter degree and antibacterial activity of bitter components. Thus, it is confirmed further that bitter components are the material foundation of medicinal effectiveness of bitter herbs.

Circulating tumor cells (CTCs) play an important role in cancer recurrence and metastasis, which are the principal reasons to death. In recent studies, it has been reported that platelets are closely associated with CTCs for inducing epithelial-mesenchymal-like transition, pro-angiogenesis, tumor thrombus and immunosuppression, and they can accelerate the progression of tumor directly. This review summarizes that how platelets affect generation and metastasis of CTCs in order to find out new evidences and direction for treatment of cancer. Copyright © 2014 by TUMOR.
