DATA RETRIEVAL：We performed a bibliometric analysis of studies on spinal cord injury-induced neurogenic bladder using the Web of Science.Data retrieval was performed using key words＂spinal cord injury＂,＂spinal injury＂,＂neurogenic bladder＂,＂neuropathic bladder＂,＂neurogenic lower urinary tract dysfunction＂,＂neurogenic voiding dysfunction＂,＂neurogenic urination disorder＂and ＂neurogenic vesicourethral dysfunction＂. SELECTION CRITERIA：Inclusion criteria：（a）published peer-reviewed articles on spinal cord injury-induced neurogenic bladder indexed in the Web of Science;（b）type of articles：original research articles and reviews;（c）year of publication：no limitation.Exclusion criteria：（a）articles that required manual searching or telephone access;（b）Corrected papers and book chapters.

Methods: Between March 2005 and September 2006, a total 19 patients;16 patients with overactive bladder (5 neurologic, 11 idiopathic), 2 with nocturnal enuresis, 1 with interstitial cystitis, intravesical BTX-A injection was applied. Except one patient, 18 patients with a median age 46 (20 - 80) were registered to the study. Patients were examined at postoperative 3 weeks and 6 months with ICIQ-SF (International Consultation on Incontinence Questionnaire-Short Form) and satisfaction forms used in our clinic. Results: The median follow-up time was 16 months (6 - 18). When evaluated according to diagnosis, symptoms were improved 100% in neurologic overactive bladder (5/5), 80% in idiopathic overactivity (8/10), 50% in nocturnal enuresis (1/2). In one patient with interstitial cystitis there was no improvement. Median efficiency time of BTX-A treatment was 6 months (1 - 17). At 3 weeks and 6 months after the treatment, ICIQ-SF score was decreased to 3.6 and 7.5 respectively from preoperative level of 18.7. Quality of life scores at preoperative, 3 week and 6 months were 9.7, 2.7 and 4.3 respectively. Except 3 patients with overactive neurologic bladder because of spinal cord injury, symptoms of patients with pollacuria and nocturia decreased at 3. week. Even if these rates increased at 6 months they still were significantly less than preoperative status. The spinal cord injured 3 patients had clean intermittent catheterization per 1 hour and had urinary incontinence between the catheterizations preoperatively, however at 3 weeks and 6 months the intervals of catheterisations was 4 hours and 3 hours respectively and also the urinary incontinance between the catheterisations improved. At patient satisfactions, 78% of patients declared that they were pleased and underwent the procedure again and will recommend it to their relatives with similar problems. One patient had a complication as tansient weakness on her legs. Conclusion: BTX-A injections provide an alternative treatment before surgery at overactive bladder especially for those who doesn’t response to medical treatment or cannot use antimuscarinics because of their side effects. Further studies with a greater number of patients are needed for determining the effectiveness of BTX-A on patients with voiding dysfunctions.展开更多

Conclusion: BTX-A injections provide an alternative treatment before surgery at overactive bladder especially for those who doesn’t response to medical treatment or cannot use antimuscarinics because of their side effects. Further studies with a greater number of patients are needed for determining the effectiveness of BTX-A on patients with voiding dysfunctions.
文摘目的:探讨膀胱癌细胞中细胞色素c氧化酶亚基7A2(COX7A2)基因的表达,及其与顺铂联用对膀胱癌J82细胞增殖、凋亡及线粒体功能影响。方法:采用生物信息学方法分析COX7A2在膀胱癌患者中的表达,并在J82细胞中进行验证。功能实验分为对照组(仅转染阴性对照siNC)、siRNA组(仅转染COX7A2的siRNA)、对照组+顺铂组(先转染阴性对照后用顺铂处理)和siRNA+顺铂组(先敲低COX7A2后用顺铂处理)。CCK-8、Transwell迁移能力测试和克隆增殖实验检测对照组和siRNA组中J82细胞的增殖、迁移能力。采用相应试剂盒检测各组细胞的ATP水平、活性氧(ROS)水平及线粒体膜电位(ΔΨm),以评估线粒体功能。流式细胞术检测各组细胞凋亡,以反映细胞的线粒体状态与对顺铂治疗的响应性关系。进一步通过癌症治疗响应基因标识数据库(CTR-DB),分析COX7A2与接受顺铂联合治疗的膀胱癌患者预后的关系。结果:生物信息学分析与生存曲线显示,COX7A2在膀胱癌患者中高表达并且与患者预后不良有关联。COX7A2在J82细胞中呈高表达(P<0.05)。在未经顺铂处理时,与对照组相比,siRNA组J82细胞增殖、迁移和克隆形成能力均显著下降(均P<0.001),而线粒体的ATP表达减少(P<0.01)、ROS表达量增多(P<0.0001)、MMP发生去极化(P<0.0001),凋亡水平增加(P<0.05);顺铂处理后,与对照组+顺铂相比,siRNA+顺铂组ATP表达减少(P<0.01)、ROS表达量增多(P<0.0001)、MMP发生去极化(P<0.0001),线粒体功能受损,凋亡水平增加(P<0.001)。CTR-DB数据库生信分析显示,5例接受顺铂+多柔比星+甲氨蝶呤+长春碱联合治疗的膀胱癌患者中,有应答者比无应答者COX7A2中位RNA表达量低(中位表达量:4501 vs 5009),12例铂类药物联合治疗的膀胱癌患者中有应答者比无应答者COX7A2中位RNA表达量低(中位表达量:2947 vs 3035),由于样本量有限,虽观察到趋势但无统计学意义。结论:敲低COX7A2可通过损伤线粒体功能,抑制膀胱癌细胞增殖与迁移,并可能由此增强细胞对顺铂诱导凋亡的敏感性。
