Objective To detect the expression of peripheral blood free prostate specific antigen (fSPA),total prostate specific antigen (tSPA),prostate specific antigen density (PSAD) and prostate cancer gene 3 (PCA3) in prostate disease,and the significance of combined detection of fSPA,tSPA and PCA3.Methods 67 patients with prostate cancer,75 patients with prostatic hyperplasia and 70 healthy male were selected as the research objects from Dec.2014 to Jul.2016.The serum level of fSPA and tSPA was detected by chemiluminescence immune staining method.The prostate volume was tested by ultrasonic sound and PSAD value was calculated.The total RNA was extracted by Trizol,and the serum PCA3 mRNA expression was detected by RT-PCR.The specificity and sensitivity of combined detection of fSPA,tSPA and PCA3 were analyzed.Results The serum levels of fSPA,tSPA,PSAD and PCA3 in prostate cancer were significantly higher than those in patients with prostatic hyperplasia and healthy male,and they were higher in patients with hyperplasia of prostate than in healthy male,and the differences had statistical significance (P＜0.01).The serum levels of fSPA,tSPA,PSAD and PCA3 were higher in patients with Gleason score ≥7 points and in T3-T4 stage than in patients with Gleason score ＜7 and in T1-T2 stage,and the difference had statistical significance (P＜0.01).The serum levels of fSPA,tSPA,PSAD and PCA3 were positively correlated with Gleason score and TMN pathological stage,and the difference had statistical significance (P＜0.01).The AUC value of fSPA,tSPA,PSAD and PCA3 in diagnosis of prostate cancer was 0.53,0.57,0.63 and 0.75,and the AUC value of combined detection was 0.92.The combined detection efficiency was higher than the single index.The specificity of fSPA,tSPA,PSAD and PCA3 was 67.16％,68.66％,73.13％ and 85.07％,and the sensitivity was 71.64％,70.15％,74.63％ and 82.09％ respectively.The specificity of combined detection was 97.01％,the sensitivity was 92.54％,and the difference had statistical significance (P＜0.01).Conclusion The serum level of fSPA,tSPA,PSAD and PCA3 is increased in prostate disease,and is negatively correlated with Gleason score and TMN pathological stage.The combined detection of fSPA,tSPA,PSAD and PCA3 can improve the sensitivity and specificity of prostate disease diagnosis,and is of high clinical value.

Objective To investigate the expression and clinical significance of serum neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1) and serum cystain C (CysC) in patients with renal tumor. Methods A total of 120 patients with renal tumor diagnosed in International Hospital of Zhejiang University from January 2016 and March 2016 was selected as the research object, and 60 patient medical volunteers were selected as control. The levels of NGAL and KIM-1 were determined by enzyme-linked immunosorbent assay ( ELISA) method, and the levels of serum CysC were determined by electrochemical luminescence method. The levels of NGAL, KIM-1, and CysC were compared, and their relevance was analyzed. Results The levels of NGAL, KIM-1, and CysC in research object were signifi-cantly higher than the control group; the levels of NGAL, KIM-1, and CysC in malignant tumor patients were significantly higher than the benign tumor;the levels of NGAL, KIM-1, and CysC in one level of ser-um tumor were lower than the two levels, three levels, and four levels of tumor patients. With the more Furhman grading, the levels of NGAL, KIM-1, and CysC were higher, the differences were statistically sig-nificant (P<0. 05). The levels of serum NGAL, KIM-1, and CysC were significantly related to renal dam-age degree. The levels of serum NGAL were significantly positively related to KIM-1 and CysC ( r= 0. 812 and 0. 765 ) . The levels of serum KIM-1 expression were significantly positively related to CysC ( r =0. 832) (P<0. 05). Multiple regression analysis showed that the levels of serum NGAL, KIM-1, and CysC were significantly related to patients with renal tumor Furhman classification ( P<0. 05 ) . Conclusions The levels of NGAL, KIM-1 and CysC were significantly increased in patients with renal tumor renal tumor, the higher the clinical stage, the higher expressive level, and were significantly related to renal damage de-gree. NGAL, KIM-1, and CysC can be used as the diagnostic markers of renal tumor.

Objective To evaluate the effectiveness and safety of terazosin in the treatment of Chinese benign prostatic hyperplasia (BPH) patients. Methods A multicenter prospective postmarketing observational study was conducted from June 2007 to March 2008 in 32 urologic centers.Patients were given terazosin for 4 weeks according to the routine medical care procedures following instructions. Effectiveness evaluation included the primary endpoint focusing on the changes in IPSS total score at the end of 2nd and 4th week compared with the baseline. The secondary endpoints were the changes in Qmax and QOL at the end of 4th week, diastolic and systolic blood pressures at the end of 2nd and 4th week compared with the baseline and the discontinuation rate of terazosin within the four weeks. Safety was assessed by adverse events. Results There were 1006 patients included in this study (FAS) and 992 patients (PP) completed the study. Among them, there were 344 patients having hypertension. The total IPSS score reduced from 22.32±6. 13 at baseline to 16. 98±5.92 at the end of the 2nd week and to 14.00±5. 52 at the end of the 4th week in FAS population (P＜0. 01).The total IPSS score changed from 22.32±6.15 at baseline to 16. 96±5.93 at the end of the 2nd week and to 13. 95±5.52 at the end of the 4th week in the PP population (P＜0.01). The efficacy rate was 26.54% at the 2-week treatment and 60.64% at the 4-week treatment, which was defined as obtaining improvement by 30% compared with the baseline. Patient's IPSS in different age groups with different prostatic hyperplasia levels and patients combined with or without 5-α reductase inhibitors were all decreased significantly(P＜0.01). With 4-week treatment of terazosin, Qmax and QOL were improved significantly by 32% and 45% (P＜0.01). Terazosin decreased BPH patient blood pressure with untreated or uncontrolled hypertension (P＜0.05), but had little influence on normal blood pressure of those under control. The incidence of adverse reactions was low. The most common adverse event was dizziness (3.68%). At the end of the study, 960 subjects (95%) were taking drug continuously.Conclasions Terazosin can significantly improve the symptoms and quality of life in Chinese BPH patients with good safety and compliance.

Objective To research the clinical manifestations of renal tuberculosis and improve the diagnosis and treatment of renal tuberculosis. Methods From 1993 to 2007,223 cases of renal tuberculosis were hospitalized. Retrospective analysis was complied for all the cases about age, clinical manifestations, imaging and treatment. Results The incidence rates of the renal tuberculosis were obviously higher in the 20-40 years old(41.7%) and in the 41-54 years old (36.3%). The course of this disease was from 1 day to 30 years(mean 38. 5 months). Only 36 patients (16.1%) were made a definite diagnosis when they went to see a doctor primary. The miediagnosis of urinary tract infec-tions( 50.3%) was most frequent. The clinical manifestations of most patients included frequency(54.7%), urgency(50.2%), odynuria(42.2%)and hematuria(58.7%). About 58. 3% patients pres-ented with over 3 kinds of above manifestations. The positive yield of the tuberculin test in urine was only 41.9%. The positive diagnostic rate of renal tuberculosis was only 35.7% in KUB+IVU,72.2%in Type-B Ultrasonic, 76.0% in CT test. One hundred and seventy-three cases were performed with nephrectomy(78.6%) and partial nephrectomy(21.4%). Two cases were treated with dialysis due to uremia. Standard medication was taken for the other 48 patiernts, and effective for 41 cases. Conclu-sions The incidence of atypical renal tuberculosis is increasing. More attention must be paid especially to those patients with urinary infection.

Objective To review the diagnosis and treatment of extra-adrenal pheochromocytoma with a 34cases report. Methods Thirty-four cases of extra-adrenal pheochromocytoma were retrospectively analyzed. Hypertension was observed in 27 cases. Abdominal pain was seen in 10 patients and intermittent hematuria in 2 patients. Serum and urinary catecholamine and urinary VMA were measured in 34 cases. The level of serum or urinary catecholamine elevated in 20 cases and urine VMA elevated in 24 cases. Thirty-four cases had ultrasound examination,25 cases underwent CT scan and 6 cases underwent MER scan.Results Pheochromocytomas of 12 cases were located in the renal hilum, 2 in the lower pole of the left kidney, 1 in the posterior aspect of the inferior vena cava, 3 in the interaortocaval region, 2 in the anterior aspect of the abdominal aorta, 1 in the anterior of the right common iliac artery, 1 in the hilum of the liver, 1 in the posterior o{ the pancreas, 2 in the bladder wall, 1 in the posterior of the descending colon, and 8 cases of multifoci. Twenty-two cases of extraadrenal pheochromocytoma were benign and 12 cases were malignant. Thirty cases were followed up from 6 months to 13 years. Among 27 cases with hypertension, the blood pressure of 22 patients returned to normal and 5 cases were still hypertensive. Nine cases of malignant pheochromocytoma all had tumor recurrence or metastases at one year postoperatively. Six patients died during followed-up from 6 months to 3 years, including 3 cases died of cerebral hemorrhage and 3 cases of tumor metastases. Three cases got stable with 131Ⅰ-MIBG radiotheraphy.Conclusions The accurate detecting extra-adrenal pheochromocytoma is difficult. CT scan could be reliable in localizing the lesions. Surgical resection of the tumor could be the best therapy. Patients of malignant extra-adrenal pheochromocytoma may be treated with 131Ⅰ-MIBG after surgical therapy.

Objective To compare the clinical features and results between transperitoneal laparoscopic radical prostatectomy and extraperitoneal laparoscopic radical prostatectomy.Methods Thirty-three prostate cancer patients treated with laparoscopic radical prostatectomy. Among them,21 cases had been done transperitoneally and 12 cases had been done extroperitoneally. The two different approaches were evaluated and compared in respects of operating time, estimated blood loss, complications during surgery, postoperative complications, intestinal function recovery time, catheterization time and length of hospital stay.Results All the surgeries had completed successfully without conversion to open surgery. For transperitoneal approach and extraperitoneal approach, the operating time was (299±46)min and (309±64)min, blood loss was (618±448)ml and (677±469)ml. There were 3 cases with severe blood loss, 2 cases with bladder injuries and 1 case with ureteral injury in transperitoneal approach group. There were 1 case with severe blood loss, 1 case with obturator never injury, 1 case with cysto-ureteral injury and 1 case with peritoneum injury in extraperitoneal approach group. For transperitoneal approach and extraperitoneal approach,the catheterization time was(14.6±3.8)d and (12.3±2.9)d, intestinal function recovery time was (2.7±0.7)d and (2.1±0.5)d, length of hospital stay was (17.0±3.6)d and (11.2±3.5)d, respectively.Conclusions Laparoscopic radical prostatectomy is feasible and safe in clinical practice. Extraperitoneal approach has better vision, less impact on abdominal organs, faster recovery and shorter hospital stay comparing to transperitoneal approach.

OBJECTIVETo investigate the effect and mechanism of alpha1-adrenoceptor blocker combined with antibiotics in the treatment of chronic prostatitis.

METHODSEighty patients with chronic prostatitis were divided into two groups, one treated with alpha1-adrenoceptor blocker (Terazosin 2 mg qn) and Levo-ofloxacin (0.2 bid), and the other given Levo-ofloxacin (0.2 bid) alone for 6 weeks. Chronic prostatitis symptom index (CPSI), urodynamic data and prostatic secretion examination were compared before and after treatment.

RESULTSThe CPSI score of the treated group decreased from 31.8 +/- 7.4 to 15.5 +/-6.6, while that of the control group decreased from 30.9 +/- 7.1 to 21.4 +/- 6.2. There was significant difference between the two groups (P < 0.05). The maximum flow rates before and after the combined treatment were 16.5 +/- 6.3 ml/s and 20.4 +/- 4.6 ml/s, while those before and after Levo-ofloxacin administration were 16.1 +/-5.8 ml/s and 17.3 +/- 6.8 ml/s. The difference was significant (P < 0.05). The maximum urethral pressure of the combined treatment group decreased from 92.5 +/- 15.3 cm H2O to 72.5 +/- 13.4 cm H2O, while that of the control group decreased from 93.2 +/- 14.8 cm H2O to 91.7 +/- 13.6 cm H2O.

CONCLUSIONAlpha1-adrenoceptor blocker can lower the intraurethral pressure, which prevents urine from refluxing to the prostate. Alpha1-adrenoceptor blocker combined with antibiotics is effective for chronic prostatitis.
