蛋白激酶Cε在前列腺癌组织中表达的临床意义

目的 探讨蛋白激酶C ε(PKCε)在不同病理类型前列腺组织中的表达及与前列腺癌病理分级、分期的关系。 方法 正常前列腺(NP)组织标本10例、前列腺增生(BPH)组织标本10例、癌旁(PC)组织标本10例、前列腺癌(PCa)组织标本43例。免疫组化法检测各组织中PKCε的表达情况,分析PKCε表达与不同病理类型及PCa分级、分期的关系。 结果 PCa组PKCε表达阳性27例,BPH组无阳性表达,NP组1例,PC组2例,差异有统计学意义(P＜0.05)。PCa组Gleason评分≥8分组中PKCε表达阳性12/13例,2～4分组4/10例,5～7分组11/20例,组间差异有统计学意义(P＜0.05)。T3期PKCε表达阳性10/12例,T4期9/10例,T1、T2期分别为1/6例和7/15例,高分期与低分期组PKCε表达差异有统计学意义(P＜0.05)。PCa转移组PKCε表达阳性9/10例,未转移组18/33例,组间差异有统计学意义(P＜0.05)。PCa患者血清PSA≤20 ng/ml者PKCε表达阳性7/15例,＞20 ng/ml组20/18例,组间差异无统计学意义(P＞0.05)。 结论 PCa组织中PKCε的表达率较高,并且与PCa病理分级、分期呈正相关,临床上可考虑作为PCa预后因子之一。     

欧洲癌症研究与治疗组织风险评分表在非肌层浸润性膀胱尿路上皮癌中的临床应用初探

Objective To evaluate the feasibility of European Organization for Research and Treatment of Cancer (EORTC) risk tables in non-muscle invasive bladder cancer in Chinese patients.Methods A retrospective analysis was performed on the data from 185 patients with non-muscle invaaive urothelial bladder cancer from January 2003 to February 2009. Among the 185 patients, 128 patients were stage Ta compared with 57 patients who were stage T1. There were 87, 53 and 45 patients with grade G1, G2 and G3 respectively. Transurethral resection of the bladder tumor was performed on all the patients and all the patients received routine post-operative intravesical instillation. A telephone interview follow-up was conducted on all the patients, and the average follow-up period was 36 months. EORTC risk tables were used to calculate risk scores for recurrence and progression for each patient. The recurrence and progression rates of different risk groups were recorded and compared with the estimated rates by EORTC risk table. Statistical analysis was used for comparison. ResultsTotal 1-year recurrence rate and progression rate for these patients were 25.9% and 3.8% respectively. According to calculated values of the patients, the 1-year recurrence rates of Group 0, Group 1-4, Group 5-9, Group 10-17 were 10.4%(5/48), 21. 5%(14/65), 35. 2% (19/54), 55.6%(10/18), respectively. The 1-year progression rates of Group 0, Group 2-6, Group 7-13, Group 14-23 were 0% (0/43), 1.5% (1/67), 6. 7% (4/60), 13. 3% (2/15). There was no significant difference between the real rates and estimated rates of the EORTC risk tables (P＞0. 05). However,the 1-year recurrence and progression rates between the low risk group, the medium risk group and the high risk group showed significant differences respectively (P ＜ 0. 05 ). Conclusions The EORTC risk tables are feasible to evaluate the recurrence and progression risk of non-muscle invasive bladder cancer in the present cohort. Nevertheless, the long term value and feasibility need more research to confirm.

原发性精囊癌1例报道并文献复习

目的探讨原发性精囊癌的诊治方法。方法分析收治的原发性精囊癌1例,结合文献进行复习。结果经CT、MRI及经直肠超声（transrectalultrasound,TRUS）引导下穿刺活检确诊为精囊腺癌,行左侧精囊肿物切除、右侧精囊切除、膀胱与前列腺部分切除及左输尿管膀胱再吻合术,术后恢复良好。现已随访23个月,未见复发转移。结论原发性精囊癌临床罕见,术前诊断较为困难,TRUS引导下穿刺活检可明确诊断,应根据患者个体情况选择不同的根治性切除术。术后定期随访,注意是否复发转移。     

肾癌组织中Tim-3基因的甲基化分析

目的分析肾癌组织中Tim-3基因启动子的甲基化情况,探讨Tim-3甲基化在肾癌发生中的可能作用。方法采用甲基化特异性PCR（MSP）检测20例肾癌组织和3例癌旁组织中Tim-3基因启动子甲基化状态,分析检测结果。结果肾癌组织中有11例（55%）检测到了Tim-3基因甲基化表达,相应癌旁组织中没有检测到Tim-3基因甲基化表达。结论肾癌组织中Tim-3基因启动子发生甲基化,Tim-3基因甲基化可能与肾癌的发生发展有关。     

睾丸间质细胞瘤的诊治—附3例报告

睾丸间质细胞瘤又称Leydig细胞瘤,是睾丸性索/性腺间质肿瘤中的一种单一组织类型的肿瘤,来源于正常发育和演化的成分间质细胞。本病较少见,且该瘤的病因及自然病程尚不十分清楚,对其治疗时手术方式的选择尚存争议。     

腹腔镜及开放根治性肾输尿管膀胱切除术治疗上尿路肿瘤合并膀胱癌8例报告

目的探讨腹腔镜和开放根治性肾输尿管膀胱切除术治疗上尿路肿瘤合并膀胱癌患者的可行性和安全性。方法收集我院2004年6月至2009年3月期间收治的8例单侧上尿路肿瘤并浸润性膀胱癌行根治性肾输尿管膀胱切除术及尿流改道手术患者的临床资料并进行随访分析。结果本组8例。男7例,女1例,平均年龄56岁。术前经膀胱镜、输尿管镜、B超和CT等检查证实为单侧上尿路肿瘤并浸润性膀胱癌,其中4例左肾盂癌和2例右肾盂癌合并膀胱癌,2例为左输尿管癌合并膀胱癌。2例行腹腔镜肾输尿管膀胱切除术及回肠膀胱术,平均手术时间470min,术中平均出血量275ml,均无输血,术后肠功能恢复时间为2d,下床活动时间为4d。6例患者行开放肾输尿管膀胱全切除术,其中4例行回肠膀胱术,另2例行输尿管造口术,平均手术时间366min,平均出血量767ml,平均输血量485ml,术后肠功能恢复时间为3.3d,下床活动时间平均为6.7d。8例患者术后均未出现并发症。术后病理结果 7例为尿路上皮癌,上尿路肿瘤分期分级为T2～4N0～1M0G2,膀胱癌为T2～3N0M0G3,另1例为左肾盂鳞癌T4N1M0合并膀胱鳞癌T3N0M0。术后平均随访24.6个月,鳞癌患者术后18个月因肿瘤广泛转移死亡,余7例患者无瘤生存至今。结论单侧上尿路肿瘤合并膀胱癌可行Ⅰ期根治性肾输尿管膀胱切除术,腹腔镜下行该手术是可行及安全的,较开放手术创伤小,出血少,恢复快。     

三种方案治疗腺性膀胱炎的网络Meta分析

目的采用网络Meta分析评价单纯经尿道切除及术后联合丝裂霉素或吡柔比星膀胱灌注治疗腺性膀胱炎的疗效及安全性。方法检索Pub Med、MEDLINE、Cochrane图书馆、EMBASE、中国期刊全文数据库、中国生物医学文献数据库,纳入单纯经尿道切除术、术后联合吡柔比星或丝裂霉素膀胱灌注治疗腺性膀胱炎的随机对照研究,以治愈率、总有效率、复发率及不良反应发生率为研究指标,采用ADDIS软件进行网络Meta分析。结果共纳入22项研究(1 544例患者)。收敛性良好,非一致性检验无统计学意义(P>0.05)。联合膀胱灌注较单纯经尿道切除术的治愈率及有效率更高,术后联合吡柔比星的疗效显著优于术后联合丝裂霉素[治愈率的比值比1.63,95%可信区间(1.10,2.46);有效率的比值比1.79,95%可信区间(1.10,3.07)];此外,对比单纯经尿道切除术,联合膀胱灌注能显著降低腺性膀胱炎的复发率[联合丝裂霉素的比值比0.26,95%可信区间(0.14,0.49);联合吡柔比星的比值比0.14,95%可信区间(0.07,0.25)];丝裂霉素联合组不良反应发生率最低,但差异无统计学意义。结论联合膀胱灌注较单纯经尿道切除术能显著提高腺性膀胱炎的治愈率、总有效率并降低复发率;术后联合吡柔比星较联合丝裂霉素的治愈率及有效率更高;三种方案的不良反应发生率差异无统计学意义。本网络Meta分析的结论尚需开展更多高质量、大样本的随机对照研究加以验证。     

预防后腹腔镜治疗复杂肾囊性疾病术后尿漏的经验总结——附59例报告

目的：总结预防后腹腔镜治疗复杂肾囊性疾病术后尿漏的经验。方法：1997年4月-2008年12月术前诊断为肾囊性疾病的患者59例,予行后腹腔镜肾囊肿去顶术（术后诊断为单纯肾囊肿36例、多囊肾21例、肾盏憩室2例、肾盂旁囊肿2例）。其中2001年后收治的43例均于术前常规予输尿管逆行插管留置导管,术中经输尿管导管注射染料（亚甲蓝）,观察由亚甲蓝显示的集合系统情况,如发现集合系统损伤,即进行相应处理。结果：59例患者均顺利完成手术。术后发生尿漏并发症共5例。应用输尿管逆行插管注射染料技术前、后尿漏发生率分别是25％（4／16）、2％（1／43）,比较差异有统计学意义（P〈0．05）。术后59例随访3个月～8年,复查B超和（或）CT均未见复发。结论：术中输尿管逆行插管注射亚甲蓝可降低后腹腔镜治疗复杂肾囊性疾病术发生尿漏并发症的风险,是预防尿漏的重要措施。     

不同分型的慢性前列腺炎对精液质量的影响

目的研究不同分型的慢性前列腺炎（要么是由感染或是针对前列腺炎自身免疫引起）是否对精液的质量有恶化的影响。方法根据目前存在感染和／或针对前列腺的自身细胞免疫反应的情况将49个诊断为慢性前列腺炎的患者分组。健康正常的个体作为对照组。检查包括：精予的密度、死亡率、形态,前列腺与精囊标记物、抗精浆抗体、白细胞计数与伴随的炎性反应前细胞因子。结果最严重的畸形见于无明显感染而有针对前列腺的自身细胞免疫的患者中。此外,在此类患者的精浆中被检测到炎性反应前细胞因子的水平显著升高。结论此研究显示,伴有针对前列腺的自身细胞免疫反应的慢性前列腺炎患者在他们精液质量参数方面有重要的改变,并因此而引起不育。
