抗HLA和抗MICA抗体的表达对移植肾功能和急性排斥反应的预示作用

Objective To investigate the prediction of anti-human leukocyte antigen antibodies (HLA) and anti-major histocompatibility complex class I-related chain A antibodies (MICA) to the development of acute rejection (AR) and kidney allograft function. Methods Forty-one kidney transplant patients were prospectively tested for anti-HLA and anti-MICA. Thirty-seven patients were screened using Luminex/single-antigen beads to determine the HLA and MICA-specific antibody levels at 0,30,90, 180,360,720 and 1080 days post-transplantation. The patients and donors of HLA and MICA allele typing were determined by PCR-SSOP, and donor specific antibody (DSA) and non-donor specific antibody (NDSA) were identified.Simultaneously,their serum creatinine (SCr) levels and clinical data were analyzed. Results Nine patients (21.95 % ,9/41 ) had pre-existing anti-HLA and(or) anti-MICA, including 6 cases of anti-MICA,2 cases of anti-HLA, and one case of anti-MICA and anti-HLA. Nine patients had pre-existing DSA and NDSA. In the 37 patients, 6 patients (16.2% ) developed de novo anti-HLA, and 3 (8.1%) developed de novo antiMICA. In patients positive for de novo anti-HLA, the titer of antibody was gradually increased during the follow-up of three years. Four patients out of 9 patients with pre-existing antibodies were suffered from AR (44.4%); In 6 patients positive for de novo anti-HLA,three cases (50.0%) were suffered from AR; In three patients positive for de novo anti-MICA,no AR occurred (P＜0.05). In two patients positive for DSA of HLAⅡ antibody detected at the third and seventh day after transplantation, the renal grafts were renovecd due to rejection. The Scr levels in patients positive for pre-existing MICA with AR were higher than in those positive for pre-existing MICA without AR at each scheduled time point during the follow-up period (P＜0.05). The Scr levels in patients negative for antibodies pre-transplantation and having AR were higher than in those having no AR at each scheduled time point during the follow-up period (P＜0. 01 ). The Scr levels in patients positive for de novo HLA and MICA and having AR one month following transplantation were higher than in those negative for antibodies and having no AR (P＜0.01 ). Conclusion Pre-existing and de novo anti-HLA were the irnportant factors for the development of AR, but the mismatch of HLA and MICA alleles in donors and patients was primary causes for generation of de novo antibodies.

代谢综合征与肾透明细胞癌分级和分期相关性的研究

目的：研究代谢综合征及其各组分与肾脏透明细胞癌分级和分期之间的关系。方法：筛选2018年1月—2019年12月本院收治的153例病理确诊为肾透明细胞癌患者的资料进行回顾性分析,收集年龄、性别、吸烟、饮酒、体重指数、血压、空腹血糖、血脂水平、肿瘤直径、分级及分期等信息。肿瘤分级采用1982年Fuhrman四级分类,将Ⅰ、Ⅱ级合并成高分化组,Ⅲ、Ⅳ级合并成低分化组。根据2010年TNM分期标准,将T1a、T1b期作为低分期组,T2a、T2b期作为高分期组。计量资料比较采用t检验进行统计学分析;计数资料比较使用χ2检验;使用Logistic回归分析寻找独立危险因素。结果：肾透明细胞癌的病理分级和分期与代谢综合征有关（P < 0.05）,高血压、糖尿病、高血脂与肾透明细胞癌的病理分级、分期有关（P < 0.05）。多因素Logistic回归分析结果表明,高血压、糖尿病、高血脂是肿瘤病理分级的独立危险因素（P < 0.05）,而糖尿病和高血脂是肿瘤分期的独立危险因素（P < 0.05）。结论：肾透明细胞癌合并代谢综合征患者的Fuhrman分级、TNM分期更高。     

前列腺特异性抗原新参数在早期前列腺癌筛查中的作用

目的探讨前列腺特异性抗原(PSA)及相关新参数在前列腺癌(PCa)早期筛查的诊断作用。方法回顾性分析苏州大学附属第一医院2015年6月至2018年9月行前列腺穿刺患者的临床资料,比较新参数前列腺游离抗原比值比前列腺特异性抗原密度[(f/t)/PSAD]、PSA质量(PSAM)、PSA质量比(PSAMR)与总PSA(tPSA)、游离PSA(fPSA)、PSA游离抗原比值(f/t PSA)、前列腺特异性抗原密度(PSAD)等指标对PCa筛查的预测作用。结果本研究共纳入717例患者,其中病理确诊PCa317例,BPH 400例。当PSA在0～20ng/mL时,tPSA、f/t PSA、PSAD、(f/t)/PSAD、PSAM及PSAMR在PCa组和BPH组中差异具有显著性统计学意义(P0.05)。当PSA在20～100ng/mL时,除f/t PSA外(P0.05),tPSA、PSAD、(f/t)/PSAD、PSAM及PSAMR在两组中差异具有显著性统计学意义(P0.05)。结论 (f/t)/PSAD在PSA灰区时诊断效能最高,取截点为0.475时,灵敏度为72.28%,特异度为61.07%。PSAMR在灰区外诊断效能较好,取截点为0.135时,灵敏度为66.17%,特异度为55.95%。而PSAM对于前列腺癌的诊断作用不强。     

一次性输尿管软镜和重复性输尿管软镜治疗肾下盏结石的疗效分析

目的 探讨重复性输尿管软镜(FURS)和一次性FURS治疗肾下盏结石的疗效。方法 回顾性分析2020年1月至2021年3月在本院治疗的206例肾下盏结石患者的临床资料,根据手术方式分为重复性FURS组（154例）及一次性FURS组（52例）。比较两组的一般情况、结石侧别、结石长径、结石数量、结石密度、肾盂肾下盏漏斗夹角（IPA）等方面的差异。结果 两组的一般情况、结石侧别、结石长径、结石数量、结石密度、IPA、术后并发症、住院时间及结石清除率比较,差异均无统计学意义（均P>0.05）。重复性FURS组的手术时间高于一次性FURS组[（42.96±16.81）min vs.(37.31±14.88)min,P=0.041],而住院费用低于一次性FURS组[（23 492.60±5 151.34）元 vs. (29 262.33±2 099.96)元, P<0.001]。结石数量、结石长径、结实密度及术后并发症与手术时间均有相关性（均P<0.05）。通过logistic回归分析结果得出,结石数量、结石长径及手术方式均为影响手术时间的独立危险因素（均P<0.05）。结论 对于肾下盏结石的治疗,一次性FURS与重复性FURS的疗效相似。对于肾下盏结石数量较多、结石长径较大的患者,在经济情况的允许下,可优先选择一次性FURS,可缩短手术时间。

术前白蛋白与碱性磷酸酶比值对局限性阴茎癌术后复发的影响

目的 探讨术前白蛋白与碱性磷酸酶的比值(AAPR)与局限性阴茎癌(T1～3N0M0)术后复发的关系。方法 收集苏州大学附属第一医院2012年1月—2017年1月收治的93例局限性阴茎癌患者的临床资料,比较术后复发组与非复发组间年龄、体质指数(BMI)、AAPR、高血压、糖尿病、肿瘤直径、术后病理分级及分期的差异。Cox回归分析术后发生复发的独立危险因素。采用Kaplan-Meier法绘制生存曲线,比较高、低AAPR组间术后发生复发的差异。结果 复发组较非复发组有较高的WHO/国际泌尿外科病理学学会(ISUP)病理分级(P=0.018)和病理分期(P=0.012)、较低的AAPR(P=0.001)。Cox回归结果显示,AAPR为术后发生复发的独立危险因素(P=0.041)。生存曲线结果表明,高、低AAPR组患者与术后未发生复发的生存时间负相关(P=0.028)。结论 术前AAPR是局限性阴茎癌术后复发的独立危险因素,且与未发生复发时间相关。随着AAPR的升高,复发发生率下降,无进展生存时间延长。
