Chinese Journal of Urology 2017;38(3):216-220
Objective To explore the effects of TMPRSS2 promoted suicide gene CD-5-FC combined with phytochemicals on the proliferation and apoptosis of prostate cancer (PCa) specific cell-line 22RV1.Methods From March 2016 to October 2016 TMPRSS2-VISA-CD/UPRT'vector was used to deliver pro-drug 5-FC (5-Fluorocytosine) in to PCa specific cell-line 22RV1.Transfection effect was verified by Western-blotting.5-FC,5-FU (5-Fluorouracil) and four phytochemicals epigallocatechin gallate (ECGC),Genistein,Daidzein,and Equol were selected in this study.MTS assay was performed to select dosages,which can kill 10%-40% of 22RV1 cells,from their pre-set drug concentrations,respectively.According to their select concentrations,either 5-FC plasmid or 5-FU in combination with one of four phytochemicals were added in 22RV1 cells in orders,and then cultured them together.Besides,these four phytochemicals were added in 22RV1 cells individually regarding their selecting concentrations and cultured at the same time.Cell viability was detected by MTS assay on 24hrs,48hrs and 72hrs.Comparing the cell killing rates between the combination groups and each single drug groups on cell-line 22RV1.Results TMPRSS2-VISA-CD/UPRT'plasmid with 5-FC was transfected on PCa specific cell-line 22RV1 successfully.The most obvious transfection occurred on 48hrs.The selected concentration of the pro-drug 5-FC were 83.32 μmol/L and 833.20 μmol/L,5-FU were 76.87 mol/L and 768.70 μmol/L.The concentrations of four phytochemical agents were 2.00 μmol/L,10.00 μmol/L and 20.00 μmol/L.In term of the cell killing numbers,results showed that the combination treatment of 83.32 μmol/L 5-FC/ 76.87μmol/L 5-FU and 10.00 μmol/L/20.00 μmol/L four phytochemicals compared with 10.00 μmol/L/20.00 μmol/L single treatment of four phytochemicals,respectively,there was no significant difference (P >0.05),while the combination treatment of 833.20 μmol/L 5-FC/768.70 μ mol/L 5-FU and 2.00 μmol/L/10.00 μmol/L four phytochemicals compared with 2.00 μ mol/L/10.00 μmol/L single treatment of four phytochemicals,respectively,there was a significant difference (P < 0.05).In addition,this study proved that 83.32 μmol/L 5-FC and 76.87 μmol/L 5-FU,833.20 μmol/L 5-FC and 768.70 μmol/L 5-FU reached the same cell killing effect,and there was no statistical difference (P > 0.05).Thus the suicide gene transfection was successful,and its function was the same as the effect of cytotoxic drugs.Conclusions This study has proved that this plasmid with 5-FC suicide gene system can be successfully and efficiently transfected into PCa cells 22RV1.As the pro-drug of 5-FU,5-FC got similar treatment effect with 5-FU,and inhibited cell proliferation.There was no synergistic reaction of enhancing cell apoptosis after combined phytochemical drugs EGCG,Genistein,Daidzen,Equol with suicide gene therapy on 22RV1 cell-line.

Objective:To investigate the mechanism of nape cluster acupuncture in the treatment of acute cerebral infarction. Methods: Eighty patients with acute cerebral infarction were selected and randomly allocated to group A and B. Group B was given routine treatment for acute phase and Group A was added with the nape cluster acupuncture based upon the treatment for Group B. The treatment was given twice daily, with 15 d as a course of the treatments, to observe the decreasing situation in the score of the nerve function defects and changes in plasma ET content. Results:There were significant differences in the score of the nerve function defects and plasma ET content before and after treatments in two groups (P<0.05), but there was significant difference between Group A and Group B after treatment (P<0.05), indicating the curative effect was better in Group A than in Group B.Conclusion: Nape cluster acupuncture can be used to effectively treat acute cerebral infarction and obviously decrease plasma ET content and reduce the score of the nerve function defects. The findings also proves that the therapeutic effect was obviously better than single medication, if nape cluster acupuncture was combined in the treatment of the acute cerebral infarction.

Objective To evaluate the clinical efficacy of percutaneous endoscopic lumbar discectomy (PELD) on treatment of far lateral lumbar disc herniation (FLDH). Methods We retrospectively analyzed 27 patients with FLDH underwent percutaneous endoscopic lumbar discectomy from June 2014 to September 2015, age from 41 to 64, average 52.3. The average operation time, intraoperative blood loss and length of hospital stay were collected. The lumbocrural pain perception of patients before and after surgery was assessed by visual analog scale (VAS) and postoperative lumbar functional recovery after surgery by modified MacNab criteria. Results Average operation time was 69 min (58~109 min), intraoperative blood loss was 18 ml (11~40 ml), and length of stay was 5.0 d (3.0 ~ 10.0 d). VAS score from (8.12 ± 1.25) preoperatively improved to (2.80 ± 1.12) at the 3rd d after operation, (1.59 ± 1.06) at 3 months after operation, and (1.31 ± 0.89) at the last follow-up after operation; There was a statistical difference between preoperative scores and postoperative scores (P < 0.05). Modified MacNab criteria was a ratio of 88.9%. Conclusions PELD on the treatment of far lateral lumbar disc herniation have small area of trauma, faster postoperative recovering and several other advantages,which is a safe and effective minimally invasive surgery.
