Echinococcosis (CE) is an infection which is caused by the larval stage of a tapeworm and is endemic in stockbreeding regions of developing countries. The kidney is the most commonly affected organ in the urinary tract. However, reports on renal hydatid disease are limited in the literature, and usually there are no specific clinical characteristics and promising operative methods. The purpose of this study is to assess the most appropriate surgical technique for the patient with urinary tract CE. We retrospectively analyzed thirty patients with renal hydatid cysts who received different surgical treatments in the urology department of the First Affiliated Hospital of Xinjiang Medical University from February 1985 to April 2010. Twenty patients were males and ten were females. The diagnostic accuracy was 74%, 87.5%, and 66.6% respectively by using of ultrasound, CT, and laboratory tests. Thirty patients were followed up for 1–15 years after surgery. One patient experienced a recurrence of renal CE. The ultrasound, CT, and immunological tests are an important means of diagnosis. The surgical treatment principle of renal hydatid should be based on residual renal function, hydatid cyst size, number, location, and surgical techniques to determine the surgical plan to retain the renal function.

We conclude that serum miR-21 and miR106a are expected to be molecular markers for RCC.

BackgroundThe aim of this study was to establish a culture method for mouse dendritic cells (DCs) in vitro and observe their morphology at different growth stages and their ability to induce the proliferation of T lymphocytes.Material/MethodsGranulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin-4 (IL-4) were used in combination to induce differentiation of mouse bone marrow (BM) mononucleocytes into DCs. The derived DCs were then assessed for morphology, phenotype, and function.ResultsThe mouse BM-derived mononucleocytes had altered cell morphology 3 days after induction by GM-CSF and IL-4 and grew into colonies. Typical dendrites appeared 8 days after induction. Many mature DCs were generated, with typical dendritic morphology observed under scanning electron microscopy. Expression levels of CD11c, a specific marker of BM-derived DCs, and of co-stimulatory molecules such as CD40, CD80, CD86, and MHC-II were elevated in the mature DCs. Furthermore, the mature DCs displayed a strong potency in stimulating the proliferation of syngenic or allogenic T lymphocytes.ConclusionsMouse BM-derived mononucleocytes cultured in vitro can produce a large number of DCs, as well as immature DCs, in high purity. The described in vitro culture method lays a foundation for further investigations of anti-tumor vaccines.

In this study, we investigated the mechanism of miR-200c-3p and SLC6A1 in regulating cell activity of clear cell renal cell carcinoma (CCRCC). The mRNA and miRNA expressions of tissue specimens were analyzed by CapitalBio Corporation (Beijing, China). The expression of SLC6A1 in CCRCC cells was examined through qRT-PCR and western blot. The migration and invasion ability of 786-O cells was testified by transwell assay after transfected. 786-O cell proliferation ability was detected by MTT assay. Dual luciferase reporter assay verified the association between SLC6A1 and miR-200c-3p. SLC6A1 was high expressed and miR-200c-3p was low expressed in CCRCC tissues and cells. Besides, lower SLC6A1 expression indicated longer survival time and higher survival rate. MiR-200c-3p could directly target at SLC6A1 and reduce its expression. MiR-200c-3p inhibited the proliferation, migration and invasion in 786-O cells by down-regulating SLC6A1 expression. The results suggested that the miR-200c-3p served as a suppressor for CCRCC via down-regulating SLC6A1.

Smoking affects the prognosis of patient with NMIBC, which is still controversial; however, among ever smokers, a high cumulative exposure smoking can significantly increase the risk of tumor recurrence. Quitting smoking might be associated with a lower recurrence rate for patients with NMIBC.
