Objective To investigate the surgical technique and clinical effectiveness of retroperitoneal laparoscopic nephroureterectomy with transurethral bladder-cuff excision and open nephroureterectomy in pelvis carcinoma. Methods We retrospectively analysed the records of all 62 patients who underwent retroperitoneal laparoscopic or open nephroureterectomy in Tianjin Dagang Hospital or the Second Affiliated Hospital of Tianjin Medical University from July 2001 to July 2009. Variables analyse were compared including operative time, blood loss, turning to open operation, complications, length of stay, tumor recurrence and metastasis. Groups were compared using Student's t-test, and a probability (P) value of less than 0.05 was taken to indicate statistical significance. Results The respective mean operative duration [(47.34±39.16) vs (118.17±44.65) ml], length of hospital stay [(9.15±2.19) vs (11.64±3.71) d], time to ambulation [(3.58±0.79) vs (5.67±1.24) d]and blood loss [(70.64±27.33) vs (118.17±44.65) ml]in retroperitoneal laparoscopic nephroureterectomy with transurethral bladder-cuff excision group was significantly reduce to open nephroureterectomy group (t = 3.3167, 2.0587, 8.0494, 5.1777, P ＜0.05). There was no significantly difference between two groups in complication of during operation and post operation [4.8 % (2/42) vs 5.0 %(1/20), 0 vs 0, respectively](P ＞0.05). 4 cases were failed and conversed to open surgery in retroperitoneal laparoscopic nephroureterectomy group. During the follow up period range from 8-48 months, there was no significantly difference between two groups in tumor recurrence and metastasis [4.8 % (2/42) vs 5.0 % (1/20),2.4 % (1/42) vs 5.0 % (1/20), respectively](P ＞0.05). Conclusion Retroperitoneal laparoscopy in upper urinary tract transitional carcinoma uses a small incision, incurs less blood loss, and allows for a more rapid recovery, suggesting it is a safe and effective method for treating patients with renal and pelvis cancer.

Objective:To research the relationship of urinary cytology positive rate with the grade and stage of primary ureter uroepithelium cancer.Methods:A total of 104 cases of primary ureter uroepithelium cancer were recruited in this study.The urine of all paitents was collected for preoperative urinary cytology de-tection.The urinary cytology detection rates were compared among different grades and stages of primary ureter uroepithelium cancer.Results:The overall unnary cytology positive rate of primary ureter uroepithelium cancer was 34.26%.The overall urinary cytology positive rate was 43.59%in the advanced stage group and 11.54%in the low stage group,with a significant difference(X2=8.740, P=0.003).The difference in positive rate between the advanced stage group and the low stage group in the high grade with inferior segment group of primary ureter uroepithelium cancer was statistically significant(X2=10.628,P=0.001).The difference in positive rate between the advanced stage group and the low stage group in the high grade group of primary ureter uroepithelium cancer was statistically significant(X2=5.678,P=0.01 7).The difference in positive rate be-tween the high grade group and the low grade group in low stage group of primary ureter uroepithelium can-cer was statistically significant(X2=12.860,P=0.001).Conclusion:The unnary cytology positive rate of primary ureter uroepithelium cancer of high grade and low stage is higher.

OBJECTIVETo evaluate the value of taking surgical margin specimens during transurethral resection of bladder tumor(TURBT) in the diagnosis and treatment of non-muscle invasive bladder cancer.

METHODSThe data of 356 patients with non-muscle invasive bladder cancer from June 2009 to January 2014 were analyzed retrospectively. A standardized protocol were performed during TURBT in 176 patients(surgical margin group), by taking surgical margin specimens from tumor base and 'normal'-appearing margin sites. The other 180 cases merely received general TURBT (general group). To observe the positive rate of surgical margin specimens and whether the diagnosis and treatment plan changed in the surgical margin group. Using Chi-square test to compare the recurrence and progression rates between surgical margin and general groups. To compare their recurrence-free survival time by Mann-Whitney U test. Results Of these 176 surgical margin specimens, the positive rate was 19. 3% (34/176),which consists of tumor base 11. 9% (21/176) and tumor normal-appearing margin 7. 4% (13/176). Following with urothelial carcinoma Ta stage in 1. 7% (3/176), T1 stage in 5. 7% (10/176), T2 stage in 8. 0% (14/176), carcinoma in situ (Tis) in 4. 0% (7/176). Among these 176 patients final diagnosis were changed in 10. 8% (19/176) patients due to the specimens results, and 18. 2% (32/176) patients altered their treatment plans. All 356 patients with a mean follow-up of 36. 8 months (6 to 60 months). Two groups of patients(surgical margin group vs. general group) recurrence rates respectively were 22. 2% (39/176) vs. 35. 6% (64/180), recurrence-free survival time were 33. 0 months vs. 23. 5 months and progression rates were 5. 7% (10/176) vs. 10. 6% (19/180). Compared with general group, patients who were taken additional surgical margin specimens showed significantly lower recurrence rate (χ2 = 7. 677, P = 0. 007) and longer recurrence-free survival time (U = 12 605,P = 0. 001). While the progression rate showed no statistical difference between them (χ2 = 2. 825, P = 0. 121).

CONCLUSIONTaking additional surgical margin specimens during transurethral resection of bladder tumor is helpful for pathological diagnosis and the planning of further treatment.

Objective To review the clinical and pathologic features of xanthogranulomatous cystitis (XC). Methods The clinical and pathologic data of 3 patients (2 females and 1 male, mean age, 37.3 year, age range, 24-50 year) with XC were reported in combination with review of the relevant literature. All 3 cases had recurrences cystitis-like symptoms, 2 cases had lower abdominal pain.1 case found low abdominal palpable mass during physical examination. Ultra sonography and CT revealed solid mass at the dome of the bladder. Partial cystectomy was performed on 2 patients, the rest 1 was case treated as urachal carcinoma.Results Postoperative pathology confirmed XC. Pathological features were as follows: xanthoma cells (lipidladenmacrophages), multinucleated giant cells and cholesterol clefts. With 12-36 (mean 28) months follow-up, there was no recurrence and cystitis-like symptoms on these patients. Conclusions XC is a rare disease. XC is usually identified by pathology. The presence of a concomitant neoplasm should be considered when the diagnosis of XC is made.Surgical resection could be a curative treatment.

Objective: To construct siRNA plasmid expression vector in order to knockdown E2F-3 activity. Methods: Sixty-four base-pair oligos for hairpin RNA expression, which targeted E2F-3 gene, were chemically synthesized and annealed. The pRNAT-U6.1/Neo vector was linearized with Bam HI and HindⅢ. Finally, the annealed oligos were inserted into the lined pRNAT-U6.1/Neo to construct RNAi plasmid(pRNAT-U6.1-E2F-3/Neo). The reconstructed RNAi plasmids were i-dentified by electrophoresis after digestion with BamHI and Hind Ⅲ, and were confirmed by sequencing analysis. Results: The recombinant pRNAT-U6.1-E2F-3/Neo vector was identified by polymerase chain reaction, and confirmed by sequencing analysis. The results demonstrated that 64 bp had been inserted into the expected site. Furthermore, the insertion sequence was exactly correct and no mutation site was found. Conclusion: The pRNAT-U6.1-E2F-3/Neo RNAi system was constructed successfully. This will facilitate the study of E2F-3 in bladder cancer cell lines.

Objective This study is to investigate the expressions of MACC1 and c-Met genes in prostate cancer tis?sues and to explore the relationship between these gene expressions with the development, invasion and metastasis of pros?tate cancer. Methods The expressions of MACC1 and c-Met genes were examined in 30 cases of benign prostatic hyperpla?sia and 67 cases of prostate cancer using citron acid-microwave-SP immunohistochemical method and analysed with their clinical pathological features. Results Expressions of MACC1 and c-Met in prostate tissues show statistical difference ac?cording to Gleason score, PSA level, pathological stages and whether bone metastasis occurs after radical surgery ( P<0.05 or P < 0.01), but their expressions in prostate tissue show no significant difference among different sex, age and whether smoking or not. Expression of MACC1 in prostate tissue of stageⅢandⅣcancer is significantly higher than that in benign prostatic hyperplasia (BPH) tissues (P<0.05) while the expression of c-Met only shows statistical difference in prostate tis?sue of stage Ⅳcancer compared with that in BPH (P < 0.05). There is a positive correlation between the expression of MACC1 with expression of c-Met in prostate cancer tissues (P<0.01). Kaplan-Meier curves revealed that the survival rates was lower and survival time of bone-free metastasis were shorter in patients with high MACC1 and c-Met expressions in prostate tissue than those with low expressions of MACC1 and c-Met in prostate tissue. Conclusion Expression of MACC1 and c-Met is closely related to the development, invasion and metastasis of prostate cancer, so MACC 1 and c-Met may be used as promising diagnostic and prognostic markers for prostate tumor, and as new therapeutic targets for prostate cancer.

Objective To evaluate the relationship between the CCNE1 or RIP2, identified at a single nucleotide poly?morphism, and the risk, clinic stage and pathological grade of bladder cancer. Methods Peripheral venous blood samples were obtained from 176 patients with bladder cancer and 210 controls without cancer. DNA was extracted. Polymerase chain reaction (PCR) method was used to detect CCNE1 (rs8102137) and RIP2 (rs42490) polymorphism. According to the postoper?ative pathological results, patients with bladder cancer were determined the grading and staging. The genotype differences of medium gene and the distribution gene were analyzed and compared in bladder cancer group and control group. The relation?ship of CCNE1 (rs8102137) and RIP2 (rs42490) genotypes and clinical data of patients with bladder cancer was analyzed, and the relationship of them with the genetic susceptibility to bladder cancer was also analyzed. Results The genotype dis?tribution was with good group representative in control group. The frequency of CCNE1(rs8102137) variant allele was signifi?cantly higher in bladder cancer group (40.91%) than that of control group (30.95%,OR=1.54,95%CI:1.02-2.45, P<0.05). The frequency of RIP2 (rs42490) variant allele was significantly higher in bladder cancer group (72.73%) than that of control group (62.38%, OR=1.61, 95%CI:1.04-2.48, P<0.05). There were no significant differences in gene polymorphisms of CC?NE1(rs8102137) and RIP2 (rs42490) between different pathological grades and different clinical stages of bladder cancer. Conclusion The CCNE1 (rs8102137) and RIP2 (rs42490) polymorphism have interaction in occurrence of bladder cancer process. There is higher risk of bladder cancer in individuals carrying mutant alleles than that of individuals carrying wild type.

Objective To discuss the mode of onset,clinical characteristics,treatment and prognosis of children with granulocyte sarcoma (GS),in order to provide guidance for early diagnosis and effective treatment of GS.Methods Six cases of children with GS diagnosed at the Department of Hematology,Children's Hospital Affiliated to Soochow University between June 2009 and June 2014 were analyzed,the data including the mode of onset,clinical manifestation,diagnosis,treatment and outcome.Results There were 2 cases with a painless mass onset (1 case was 2 years old,characterized by right waist mass,about 10 cm × 5 cm;the other case was 6 years old,characterized by axillary lump,about 2 cm × 3 cm),and both of them received surgical removal of the tumor,then the postoperative tumor was examined by pathologic and immunohistochemical method,and at last the primary granulocyte sarcoma was diagnosed.The third case was a 7 years old girl,she was onset characterized by scalp lump,about 2 cm × 3 cm,and was diagnosed by the pathologic and immunohistochemical method,and changes in hematological system appeared a month later and acute myeloid leukemia(AML) was confirmed by bone marrow examination.The onset ages of other 3 cases were in 10 months,1 year and 7 months,13 years and 3 months old respectively,characterized by scalp lump (about 2 cm × 3 cm),spinal canal tumor (about 1.0 cm × 1.5 cm),intracranial tumors (6.0 cm × 4.9 cm),with AML occurring at the same time,which was confirmed by surgical pathology,immunohistochemistry and bone marrow cell morphology,immune classification,chromosome,and fusion gene diagnosis.Four cases were hematopoietic malignancies by pathology,2 cases of then belonging to small round cell tumor.The immune pathology showed 5 cases of myeloperoxidase positive,CD68-positive,3 cases of CD43-positive,CD123-positive.All children CD3,CD20 levels in all children were negative.Four cases underwent surgery combined with chemotherapy,other 2 cases received surgery and then gave up treatment,1 case discontinued follow-up 3 months later,and the other case died of intracranial hemorrhage after 3 months,which induced by thrombocytopenia.The treated 4 cases were followed up 3 to 58 months,and all had disease-free survival.Conclusions Children with GS have low incidence and non-specific diagnostic criteria,its diagnosis depends on immune pathology,and the treatment is mainly in accordance with AML program for high-dose chemotherapy.The systematic chemotherapy helps to prolong overall survival;at the same time,the hematopoietic stem cell transplantation with bone marrow may help to improve the prognosis.

Objective:To investigate the relationship between the expression of Fascin protein and vascular endothelial growth factor(VEGF)and the biological behavior of bladder transitional cell carcinoma(BTCC).Methods:The expressions of Fascin and VEGF were examined by SABC(StreptAvidin-Biotin Complex)immunohistochemistry in 56 paraffin-embedded tissue specimens and 10 control samples of normal bladder tissues.Results:The positive expression rates of Fascin and VEGF were 0 in normal bladder tissue.The positive expression rates of Fascin and VEGF were 73.21% and 60.71% in BTCC(P ＜ 0.01).The higher expressions of Fascin and VEGF were related to the tumor grade,clinical stage and recurrence(P ＜ 0.01).The expression of Fascin was closely correlated with that of VEGF in BTCC(r=0.476 9,P＜ 0.01).Conclusion:The expression of Fascin may be one of parameters for understanding the biological behavior of BTCC.Fascin protein and VEGF may enhance the influence of the development of BTCC together,which may also provide theoretical foundation of chemopreventive stategy for bladder cancer in the future.
