Abstract：

Objective To investigate the value of B7-H3 in expressed prostatic secretions (EPS) in differential diagnosis of patients with inflammatory elevation of PSA in t-PSA gray zone (4-10 ng/ml). Methods One hundred and sixteen patients from the ages of 19 to 80 years (mean, 40 years) were stu-died. In the group there were 91 chronic prostatitis (CP) patients (mean age 31 years, 19-49 years), including 11 chronic bacterial prostatitis (type II) patients, 26 inflammatory nonbacterial prostatitis (IIIA) patients and 54 noninflammatory nonbacterial prostatitis (IIIB) patients. Transrectal ultrsound guided prostate biopsy was performed on 25 patients (mean age 71 years, 62-80 years) with t-PSA in gray zone (7.21±2.60 ng/ml). Five had positive results, Gleason score was 6 in two cases, 7 in two cases and 8 in one case. Twenty patients had negative results, of whom 11 patients had inflammatory cell infiltration. EPS was collected by transrectal massage, and Enzyme-linked immunosorbent assays (ELISA) were performed for B7-H3 detection. In addition, 11 normal male controls with a mean age of 30 years (24-46 years) were recruited into the study. Volunteers were excluded if they had a history of genitourinary symptoms or surgery.Results The EPS B7-H3 levels of controls, II, IIIA, IIIB groups were 49.81±11.54, 19.33±13.90, 17.67±15.76, 25.14±13.44 ng/ml, respectively. The levels of EPS B7-H3 in positive biopsy, noninflammatory negative biopsy and inflammatory negative biopsy groups were 26.30±16.32, 30.23±18.42, 10.11±5.42 ng/ml, respectively. The highest levels were found in the control group (P<0.01). Compared to the IIIB, B7-H3 levels in II and IIIA groups were significantly lower (P<0.05). There was no significantly difference between II and IIIA groups (P>0.05). The EPS B7-H3 levels in the inflammatory negative biopsy group were statistically lower than in positive biopsy and noninflammatory biopsy groups (P<0.05). But no significant differences were found among inflammatory negative biopsy, II and IIIA groups (P>0.05). Receiver operating curve (AUC=0.883, P=0.001) utilizing EPS B7-H3 levels≤16.24 ng/ml identified patients with inflammatory elevation of PSA with a sensitivity of 78.6% and a specificity of 81.8% from patients with t-PSA in gray zone. Conclusion The EPS B7-H3 detection provides a new way for differential diagnosis of patients with inflammatory elevation of PSA in t-PSA gray zone resulting in a reduction of unnecessary prostate biopsy.     

TSP-1在肾透明细胞癌与外周血中的表达及临床意义

目的 检测并分析凝血酶敏感蛋白-1(thrombospondin-1,TSP-1)在肾透明细胞癌患者肾癌、癌旁组织、正常肾组织及外周血中的表达及临床意义.方法 收集47例肾透明细胞癌患者的标本包括:47例肾癌组织、41例癌旁组织、38例正常肾组织、35例患者外周血标本,制备组织抽提液及外周血清.运用ELISA法检测三种组织及血清中TSP-1的表达,并结合临床资料分析其临床意义.结果 TSP-1在肾癌组织、癌旁组织、正常肾组织三者间的表达水平分别为36.44±4.80ng/mL、42.55±4.12ng/mL、46.55±1.55ng/mL,依次递增,三种组织间的表达水平,两两比较均有统计学差异(P均＜0.01).TSP-1在肾癌组织中的表达,随着肾癌TNM分期与Fuhrman分级的提高而均降低,且都呈负相关(r=-0.84,P＜0.01;r=-0.70,P＜0.01).结论 TSP-1在肾透明细胞癌组织中低表达,可能在抑制肿瘤血管形成过程中起重要作用;TSP-1在肾透明细胞癌组织中的表达与肾癌的TNM分期和Fuhrman分级关系密切,可作为评判肾透明细胞癌发展及恶性程度的指标.     

肾移植患者血清中可溶性B7-H3水平的变化及其临床意义

Objective To detect the serum soluble B7-H3 (sB7-H3) in patients before and after renal transplantation, and to investigate the clinical significance. Methods The serum level of sB7-H3 in 34 patients were determined before and 3, 6, 12 months after renal transplantation. Besides, 11 health adults were elected as controls. These 34 patients were divided into two groups according to HLA and/or MICA antibodies using Luminex before operation. After transplantation, all the patients were divided into two groups according to their conditions; group Ⅰ with rejection; group S with stable renal function and no rejection. Results The serum level of sB7-H3 in all 34 patients before operation was significantly higher than health controls [(27. 10 ± 13. 61) μg/L,n = 34 vs (11.61 ±3.77) μg/L,n = 11 ,P ＜0. 01], and significantly higher in patients with antibodies than in those without before operation [(34. 96 ± 17. 37) (μ/L, n = 11 vs (23. 34 ± 9. 75) (μg/L, n = 23, P ＜ 0. 05]. There was no significant difference in the serum level of sB7-H3 between control group and S group after operation (P ＞0. 05). In group Ⅰ, the serum level of sB7-H3 was increased obviously when rejection occurred [(20. 63 ±4. 28) μg/L,n = 12; (18. 95 ±2.98) μg/L,n=6; (28.36 ±19. 83) μg/L,n = 10] , as compared with group S and control group (P＜0. 01), while at the time without rejection, there was no difference among them (P ＞0. 05). Conclusion Monitoring serum sB7-H3 after renal transplantation would be clinically useful in indicating therapeutic effect and outcome of the patients.

成人输尿管囊肿的诊断和治疗（附32例报告）

目的探讨成人输尿管囊肿的诊断及治疗方法。方法回顾性分析2008年08月～2013年03月收治的32例成人输尿管囊肿患者的临床资料。所有病例均经B超、静脉肾盂造影（IVP）和膀胱镜检查确诊,分别给予观察随访、开放手术或者经尿道输尿管囊肿电切开术（TUIU）治疗。结果膀胱镜诊断符合率为100％（32／32）,IVP诊断符合率87．5％（28／32）,B超诊断符合率78．1％（25／32）。1例观察随诊,2例行开放手术,其余29例行TUIU术。术后随访3～28个月,患者临床症状和肾积水消失或减轻,无膀胱输尿管反流发生。结论TUIU是治疗成人输尿管囊肿的一种有效且重要的方法。对于合并严重的重复肾、输尿管畸形者宜采用开放性手术,并行输尿管再植术,防止术后膀胱输尿管反流。
