Tumor 2019;39(5):388-397
Objective: To systematically evaluate the optimal duration of adjuvant androgen deprivation therapy (ADT) after radiotherapy for prostate cancer. Methods: The CBM, CNKI, Wanfang, PubMed, EMbase, Cochrane Library, Clinical Trials.gov databases were searched by computer. The randomized controlled trial (RCT) on long-term and shortterm ADT for intermediate and high risk non-metastatic prostate cancer after radiotherapy were collected. The retrieval time was from the establishment of these databases to November 5, 2018. After independent screening literature, extracting data and evaluating the quality of the included studies, two researchers used RevMan 5.3 software for Meta-analysis. Results: A total of eight RCTs were selected, including 6 165 patients. Meta-analysis showed that the overall survival (OS) rate in longterm ADT group was higher than that in short-term treatment group [hazard ratio (HR) = 0.75, 95% confidence interval (CI): 0.63-0.89, P = 0.000 7]; the disease-free survival (DFS) rate in long-term ADT group was higher than that in short-term treatment group (HR = 0.81, 95% CI : 0.70-0.94, P = 0.007); the disease-specific survival (DSS) in long-term ADT group was higher than that in short-term treatment group (HR = 0.83, 95% CI : 0.71-0.96, P = 0.01); the local progress (LP) in long-term ADT group was lower than that in short-term treatment group [relative risk (RR) = 0.76, 95% CI : 0.59-0.97, P = 0.03]; the biochemical failure (BF) in long-term ADT group was lower than that in short-term treatment group (RR = 0.66, 95% CI : 0.52-0.83, P = 0.0004); the distant metastasis (DM) in long-term ADT group was lower than that in short-term treatment group (RR = 0.85, 95% CI : 0.74-0.96, P = 0.01). Conclusion: The long-term ADT treatment is superior to the shortterm treatment in OS rate, DFS rate, DSS rate, LP rate, BF rate and DM rate after radiotherapy for moderate and high risk prostate cancer. Due to the limitation of the quantity and quality of the included literatures, the above conclusion need to be verified by higher quality research.

AIM: To investigate the effect of selective silencing of SLC7a8 on uptaking L-dopa in renal tubular epithelial cells of rat (NRK-52E). METHODS: The three siRNAs targeting SLC7a8 (siRNA-1, siRNA-2, siRNA-3) were designed and synthesized. A siRNA with nonspecific coding sequence (siRNA-con) was used for control. All siRNAs were transfected into NRK-52E cells. The siRNA-con transfected group, blank control group and gene-specific silencing SLC7a8 group were set up. The efficiency of transfection was estimated by flow cytometry. The efficiency of RNA interference was detected and screened by RT-PCR preliminarily, and was followed by Western blotting at protein level. The concentrations of L-dopa uptake into the NRK-52E cells were detected by ultraviolet spectrophotometry at different time points (6, 12, 24, 36, 48, 60, 72 and 120 min). RESULTS: The transfection efficiency was 94% detected by flow cytometry. The initial screening of RT-PCR showed that the efficiencies of RNA interference of siRNA-1 and siRNA-3 were higher, and siRNA-3 was the highest at protein level determined by Western blotting. No distinctive change was found between siRNA-con treated NRK-52E and blank control cells. The L-dopa uptake at different time points (6, 12, 24, 36, 48, 60, 72 and 120min) in siRNA-interference group was lower than that in siRNA-con transfected group and blank control group. No significant difference of L-dopa uptake between siRNA-con group and blank control group was observed. CONCLUSION: RNA interference technology selectively down-regulates SLC7a8 expression in rat renal tubular epithelial cells. The L-dopa uptake is also decreased after specifically silencing the slc7a8 expression.

Objective The aim of this study was to investigate the clinical value of human serum Kallikrein 6 for the diagnosis and monitor of pithelial ovarian cancer. Methods Serum levels of KLK6 were analyzed with ELISA in 30 cases of epithelial ovarian carcinoma, 20 cases of benign ovarian tumor and 30 cases of healthy women. In the meantime, serum CAi25 was determined with chemiluminescence. Furthermore, serum levels of KLK6 and CA125 were also detected in 12 case of epithelial ovarian carcinoma with the same methods one week and the 3rd month postoperation of follow-up. Results Serum levels of KLK6 in epithelial ovarian carcinoma was higher than that in benign ovarian tumor and healthy women (P < 0.05). KLK6 also showed positive correlation with clinical stage, cytological grade, pelvic lymph node metastasis, recurrent or dead disease (P < 0. 05). On the contrary, KLK6 showed no significant correlation with pathological types (P >0. 05). After surgery of follow-up, KLK6 and CA125 were significantly decreased in 12 case of epithelial ovarian carcinoma (P < 0. 05). Furthermore, the total sensitivity and specificity of KLK6 in the diagnosis of epithelial ovarian carcinoma was 73.3% and 85.0% respectively, followed by the sensitivity to be 50. 0% and 88. 9% for the diagnosis of stage Ⅰ-Ⅱand Ⅲ-Ⅳ disease. Conclusion Our resuits showed KLK6 may be one of the reliable indexes for the diagnosis and monitor of ovarian cancer.
