1.CK20 expression in exfoliated urothelial cells of bladder cancer
Chinese Journal of Urology 2000;0(05):-
Objective To study whether CK20 expression could be served as a noninvasive test for detecting and monitoring bladder cancer. Methods Reverse transcriptase polymerase chain reaction (RT PCR) was used to determine the expression of CK20 in cells collected from the urine of 10 healthy volunteers,41 patients with bladder cancer and in 20 hematuria patients with bladder cancer excluded. Results CK20 amplification band (370bp) was obtained with mRNA extracted from TCC cells of bladder cancer. Of 41 patients with bladder cancer, 37 specimen were positive.No false positive cases were found in the 10 healthy controls and only in 3 of the 20 hematuric cases.Of the 3 false positive, 2 had pelvic cancer and 1 chronic inflammation. CK20 was positive in 23 of the 25 G 1 patients,in 8 of the 9 G 2 patients,and in 6 of the 7 G 3 patients. Conclusions The preliminary results showed that CK20 might be a potential biomarker for the noninvasive detection of bladder cancer by means of assaying urothelial cells from the voided urine specimen with RT PCR.

Tumor 2001;(2):138-139
Objective To study the malignant or benign characters of lung mini nodules for diagnosis and treatment.Methods A retrospective analysis was performed on 80 post-operative cases with pathologically confirmed malignant or benign lung mini-nodules.Results Lung mini-nodule resection cases accounted for 17.7%(80) out of a 451-cases group.Malignant cases accounted for 73.7%(59/80),benign cases 26.3%(21/80).Most of the malignant cases were squamous cell carcinoma and adenocarcinoma,while most of the benign cases were tuberculosis and inflammatory pseudo-neoplasms.As for pTNM staging in malignant cases,there were 28 in pT1N0M0,19 in pT1N1M0,1 in pT1N1M1,10in pT1N2M0 and 1 in pT1N2M1;the average survival time was 29.4 months.The accurate rate of pre-operative X-ray and CT scan was 45% and 76.2% respectively.Conclusion For patients with lung mini-nodules <2 cm CT value at 37HU,and the nature unknown ,resection is suggested.

Objective To evaluate the effect of ImmunoCyt on the early diagnosis of bladder cancer by comparing the result of cystoscopy with that of cytology. Methods Eighty-six consecutive patients with bladder cancer (mean age,63 years) were included in this group.Among them 38 had undergone transurethral resection of superficial transitional cell carcinoma and had been followed up and 48 had hematuria.These patients were evaluated with standard cytology and ImmunoCyt test.Then all the patients underwent cystoscopy and suspected lesions were biopsied. Results Transitional cell carcinoma of bladder was confirmed pathologically in 28 cases.The sensitivity of ImmunoCyt (82%) was superior to that of cytology (39%, P

Objective To evaluate the clinical effect of emergency pelvic external fixation in hemodynamically unstable patients with pelvic fracture.Methods The clinical data of 56 hemodynamically unstable patients with pelvic fracture from January 2008 to December 2013 were selected.The changes of hemoglobin,mean arterial pressure,heart rate,serum lactate,urine volume,norepinephrine dosage before and after surgery for 24 h were compared and analyzed.Results Compared with those before surgery,the levels of hemoglobin,mean arterial pressure,serum lactate,urine volume,heart rate after surgery for 24 h were significantly improved:(109 ± 12) g/L vs.(69 ±22) g/L,(87.8 ±6.5) mmHg (1 mmHg =0.133 kPa) vs.(55.8 ± 7.7) mmHg,(6.3 ± 5.1) mmol/L vs.(10.8 ± 6.6) mmol/L,(35.9 ± 9.9) ml/h vs.(17.6 ± 8.4) ml/h,(84.2 ± 15.4) times/min vs.(146.4 ± 12.1) times/min,and the norepinephrine dosage was significantly reduced:(0.8 ± 0.2) μ g/ (kg· min) vs.(2.2 ± 0.8) μ g/ (kg· min).The differences had statistical significance (P < 0.05 or < 0.01).Conclusion Bedside pelvic external fixation can rapidly improve shock symptom in hemodynamically unstable patients with pelvic fracture,which is safe and efficient.

Objective To evaluate the effect of technical improvement of radical retropubic prostatectomy (RRP) for patients with localized prostatic cancer. Methods RRP was performed in 32 cases (mean age,68 years) of prostatic cancer at clinical T 1 and T 2 stages.Technical improvements included extensive lymph node clearance,protection of the neurovascular bundle,suture and ligation of the dorsal vein complex,preservation of the distal prostatic urethra,and intussusception of the bladder neck. Results The mean operative time was 3.5 h.The mean blood loss was 450 ml;blood transfusion was conducted in 17 cases.Postoperative pathologic findings revealed tumor confined disease in 30 cases,positive surgical margin in 1, and lymph node metastasis in 1.All the patients survived and were followed up for a mean of 22 months (range 8 to 48 months),with PSA

Objective To evaluate the clinical value of cystectomy with prostate capsule sparing in orthotopic bladder replacement for bladder cancer. Methods A total of 56 male patients (mean age,62 years) with bladder cancer were included.Of them 40 cases were of primary tumors and 16 were of recurrent ones.Pathology by cystoscopy and biopsy showed transitional cell carcinoma in 53 cases and squamous cell carcinoma in 3.According to the analysis of B ultrasound,CT,MRI and cystoscopy, they were clinically diagnosed as recurrent multiple superficial tumors (n=27) and invasive tumors (n=29).Radical cystectomy with prostate capsule sparing was performed on them.Detubularized ascending colon (20 cases) or ileal segment (36 cases) was used to form a neobladder,which was anastomosed with distal portion of prostate capsule. Results Mean operative time of ascending colonic neobladder and ileal neobladder was 5 h 50 min and 6 h 20 min,with blood loss of 580 ml and 540 ml,respectively.Pathology showed pT 1N 0 in 28 cases,pT 2N 0 in 25 and pT 3N + in 3.During the follow up of 4 to 102 months (mean,42 months) 3 patients of pT 3N + died of bladder cancer and 5 died of other diseases.The cancer specific 5 year survival was 94% in cases of T 1N 0,83% in T 2N 0.At 1 year follow up,17 out of 18 patients (94%) with ascending colonic neobladder and 30 out of 30 patients (100%) with ileal neobladder were fully continent during the day,and 46 (96%) voided 1 to 2 times at night and could stay dry.Of 31 patients with preoperative adequate sexual function, 23 (74%) maintained potency postoperatively. Conclusions Radical cystectomy with distal prostate capsule sparing and reconstruction with an orthotopic neobladder is a relatively safe and reliable surgical procedure.It can improve the continence and potency without compromising the principle of tumor control.

This study was aimed to observe the influence ofQing-Chang Hua-Shi Recipe (QHR) on IL-6trans-signaling in experimental colitis mice, in order to initially explore the possible mechanisms of QHR for ulcerative colitis (UC). TNBS/ethanol was used in the establishment of colitis mice model. After intervention of medication, ELISA was used in the detection of soluble Interleukin-6 receptor (sIL-6R). Real-time PCR was used to detect the mRNA expression level of IL-6 and glycoprotein 130 (gp130). Western blot was used in the observation of protein expression of IL-6 and gp130 in the colonic mucosa. The results showed that the level of sIL-6R, the mRNA and protein expression of IL-6 and gp130 in the model group were significantly higher than that in the control group. QHR was able to reduce the sIL-6R level (P < 0.01), decreased the mRNA and protein expression of IL-6 and gp130 (P < 0.01) in the colon tissues among experimental colitis mice. It was concluded that QHR had good anti-inflammatory effects on experimental colitis mice. It might be associated with influencing IL-6trans-signaling.
