Objective To observe the effects of secoisolariciresinol (SECO) and its metabolites, enterolactone (ENL) and enterodiol (END), on proliferation of MCF-7 cell line and to the probable mechanism. Method Effect of SECO, END, ENL and genistein (GEN) on MCF-7 proliferation was investigated by MTT assay. Cell cycle arrest was measured by flow cytometry (FCM). Cell morphology was observed by optical microscope. The anticarcinogenic mechanism of SECO was analyzed. Results SECO had promotive effect on the cell growth at lower concentration (≤40 ?mol/L) but inhibition effect at higher concentration (100 ?mol/L). ENL and END, however, showed significant inhibition effect at all tested concentrations (10~100?mol/L). The cell cycle progression was arrested at G2/M phase and apoptosis was observed by optical microscope. Conclusion Effect of SECO on the MCF-7 cell proliferation depends on its concentration. Inhibition effect of SECO may relate to its metabolites ENL or END.

Background and purpose: The effects of tumor after radiotherapy and chemotherapy with tumor cell apoptosis have positive correlation. Survivin is an apoptosis suppressor gene, which is overexpressed in lung cancer. The reduction of its expression can increase lung cancer cell apoptosis. RNA interference can speciifcally and effectively blocked the expression of this gene. After accepting a dose of radiation, tumor tissues can raise the rate of gene transduction. The purpose of this study was to investigate the effects of the expression of Survivin gene suppressed by intratumor injection siRNA and radiation in lung cancer. Methods:Mouse subcutaneous transplanted with tumors were randomly divided into four groups:untreated group (group A), group with intratumor injection siRNA (group B), group with radiation (group C), group 4 Gy pre-irradiation combination with intratumor injection siRNA (group D). Two days later, mouse with different treatments were executed by cervical dislocation and stripped the subcutaneous tumors. mRNA and protein levels of Survivin gene were detected by quantitative real-time PCR (qRT-PCR) and Western blot; Cell cycle and cell apoptosis were assayed by lfow cytometry (FCM). Results:The expression of Survivin gene in mRNA and protein levels in group B, C, and D were signiifcantly reduced compared with group A. The differences of Survivin expression in mRNA level between group A and group D were statistically signiifcant. Compared with the other 3 groups, the expression of Survivin gene in group D was signiifcantly reduced, the differences were statistically signiifcant (P=0.036);The proportion of cells in S-phase of group D was (2.70±0.34)%, compared with group B [(8.93±0.75)%] and group C [(6.71±0.51)%], that was significantly reduced. The differences of the proportion of S-phase cells in group A and group D were statistically signiifcant (P=0.034);The rate of cell apoptosis in group D was (25.67 ± 0.65)%, which was signiifcantly increased compared with the rate of cell apoptosis in the other 3 groups, the differences were statistically signiifcant (F=78.82, P<0.05). Conclusion:Pre-irradiation can enhance the transduction rate of siRNA, reduce the expression of Survivin gene in lung cancer, promote cell apoptosis, and increase the sensitivity of the radiotherapy.

Objective To compare the sensitivity and specificity of mucin 7(Muc7) mRNA test with urine cytology in detection bladder cancer.Methods In 86 patients suspected with bladder cancer,RT-PCR for Muc7 mRNA and urine cytology were conducted in the same urine samples.Fif-ty-two patients with bladder transitional cell carcinoma were confirmed histologically.The sensitivity and specificity of Muc7 mRNA and urine cytology were analyzed.Results The overall sensitivity,specificity and false positive of Mue7 mRNA test were 84.6%,85.2% and 14.7% respectively.Those of urine cytology were 34.6%,91.2% and 8.8% respectively.There were no significant differences between urine cytology and Muc7 mRNA test in the specificity and false positive; however,Muc7 mRNA had significantly higher sensitivity than urine cytology in detection of bladder cancer.Conclusion The sensitivity of Muc7 mRNA test is superior to urine cytology in detection of bladder cancer.

Objective To investigate the expression of human epididymal protein 4 (HE4) in chronic kidney disease (CKD) and its clinical value.Methods From April 2014 to December 2015,Serum samples of 92 non-cancer patients diagnosed as CKD and 84 healthy controls were collected in Nantong University Hospital.HE4,BUN,Scr,Cys C and β2MG were detected.The difference of HE4 expression in different stages of CKD and the correlation of HE4 with Urea,Scr,Cys C and β2MG were analysized,respectively.ROC curve was used to evaluate the auxiliary diagnostic value of HE4,BUN,Scr,Cys C and β2MG.Results The serum HE4 expression in patients with impaired renal function was 388.2 (130.1～1 659.5)mIu/ L,(F=16.237,P=0.001).Which was significantly higher than that in the control group [38.1 (32.77 ～ 48.17)mIu/L].The serum HE4 expression was increased by the stage of renal damage and the difference was existed among different groups (P＜0.05).HE4 expression was positive related with Cys C and β2MG.The AUC of HE4,BUN,Scr,Cys C and β2MG were 0.878,0.785,0.816,0.874 and 0.819,respectively.Conlusion It needs to consider the exsits of impaired renal function when the HE4 was detected.The HE4 might be a novel early diagnostic indication for CKD.

Objective Currently,the sit-to-stand process is not well evaluated.The aim of the study is to evaluate quantitatively the reliability of posturographic parameters in the sit-to-stand process.Methods Seventy-four healthy participants were enrolled and required to finish 20-second sitting,standing and the sit-to-stand process.The computer calculated the posturographic parameters automatically.The test was repeated twice to assess the reliability at an interval of six days.Results During sitting and standing position,the intraclass correlation coefficients (ICCs) of all the parameters were above 0.50,indicating a good or fair reliability.During the standing stance and sitting phase of the sit-to-stand process,the ICCs of all the parameters were above 0.40 and 0.60 respectively,showing a good or fair reliability.Conclusions Sit-to-stand posturographic parameters are a new way to assess the position control ability among the healthy participants with a good reliability.Further study should be conducted among patients to result in better functional and effectiveness evaluation.
