Objective To investigate the expression of miR-101 in pancreatic cancer and the effect of down-regulation miR-101 on proliferation of pancreatic cancer cell line ASPC1. Methods Real-time PCR was used to determine the expression of miR-101 in pancreatic cancer, adjacent tissues and pancreatic cancer cell line ASPC-1. The miR-101 over-expression vector (peGFPc1-miR-101) was constructed and was transfected into ASPC-1 cell. Transfection efficiency was measured by fluorescence microscope. The expression of miR101in the transfected cells was detected by real-time PCR. Cell viability analysis was performed by MTT. The targeted genes of miR-101 in pancreatic cancer were scanned by the online targeted gene prediction software (target Scan). Results The expression of miR-101 was in pancreatic cancer tissues, adjacent tissues and ASPC-1 cell line, respectively. The expressions in pancreatic cancer tissues and ASPC-1 cells were significantly lower than that in adjacent tissues ( P < 0.01 ). The expression of miR 101 in transfected cells increased to 19.8 folds as much as that in the control group (P <0.01 ). Proliferation rate of transfected cells was significantly decreased, which was only 26% of primary cells ( P < 0.01 ). EZH2 was the potential targeted gene of miR-101 in pancreatic cancer. Conclusions miR-101 was weakly expressed and it may affect the proliferation of pancreatic cancer cell by inhibiting the EZH2 expression.

Objective:To summarize the clinical experiences of pediatric en-bloc kidney transplantation (EBKT) at a single center and explore the measures of improving its efficacy.Methods:Clinical data and outcomes retrospectively analyzed for 38 EBKT children between September 2014 and November 2019 from Department of Urology Affiliated Union Hospital Tongji Medical College Huazhong University of Science & Technology. The pediatric donors were aged (63.6±5.7) days with a weight of (4.1±0.2) kg. And the transplant recipients were aged (28.1±1.4) years with a weight of (48.7±4.9) kg. Serum levels of creatinine and basic profiles of both donors and recipients were recorded at Day 0/7/30/90/80/360 post-EBKT. The postoperative occurrences of such complications such as thrombosis, urine leakage, delayed graft function (DGF), proteinuria and hematoma were measured.Results:The one-year graft survival rate was 76.3%(29/38) and the recipient survival rate 100.0%(38/38). Among 29 recipients with long-term graft survival, no dialysis was required at Week 2 post-EBKT and the serum level of creatinine dropped to normal at Year 1. Thrombosis was a major post-EBKT complication with an incidence of 18.4%(7/38). The other complications included urine leakage (20.7%, 6/29), hematoma (6.9%, 2/29) and primary non-functioning kidney (2.6%, 1/38).Conclusions:As an effective way of expanding the pool of donors, pediatric EBKT is clinically feasible.
