AIM To study the boosting effect of Maximin 2 on expression of HLA DR and HLA ABC by cultured bladder cancer cell lines and compare with TNF ??IFN ?. METHODS Cell culture and FCM were used to dectect the effects of Maximin 2,TNF and IFN on the cell growth of three types of bladder cancer cell lines and HLA DR and HLA ABC expression under the IC 50 culture concentration. RESULTS Maximin 2 had show inhibition to cells growth under the small dosage. TNF ??IFN ? also had the effect on restrain all 3 cell lines growth. The expression of HLA DR was not any change in all 3 cell lines after being stimulated by Maximin 2?TNF ? and IFN ?, Maximin 2 and TNF ? can not change HLA ABC expression, IFN ? can up regulate HLA ABC expression. CONCLUSION Maximin 2 show the dose dependent effect on cell growth suppression; The mechanism of antitumor of Maximin 2 seems not relate to the enhanced expression of HLA DR or HLA ABC, TNF ? and IFN ? also not found effect to HLA DR expression. Since IFN ? are able to increase the expression of HLA ABC expression,enhanced recognization and cytotoxity of CTL to bladder cancer cells. It is may be one of the mechanism of antitumor of IFN ?.

Objective To evaluate the clinical efficacy of transurethral resection of ureteral orifice invaded by advanced prostate cancer caused hydronephrosis. Methods A retrospective study was done in 15 patients who were diagnosed by advanced prostate cancer with invasion of ureteral orifice and treated by transurethral resection of ureteral orifice and maximal androgen blockade. 24 kidneys were diagnosed as hydronephrosis by ultrasound. Before the procedure, the average serum BUN was 13.2 mmol/L (8.9~28.5), the average serum Cr was 243.3 μmol/L (126.7~369.2), the average GFR evaluated by renal radionuclide imaging was 48.6 mL/min (31.1~66.2), and the upper urinary tract was obstructed in kidneys with hydronephrosis. Results All 15 patients underwent successfully transurethral resection of ureteral orifice and discharged after 4 days stay. The average procedure time was 65 min (50~100 min) and mean blood loss was 45 mL (30~65 mL) . The patients were followed up for 2~4 weeks. Hydronephrosis examined by ultrasound was ameliorated in 18 kidneys (75%) and not obviously changed in 6 kidneys (25%) in one week after procedure. Hydronephrosis examined by ultrasound was ameliorated in 20 kidneys (83.3%) and not obviously changed in 4 kidneys (16.7%) in two weeks after procedure. Within two weeks after procedure,the average serum BUN was 10.75 mmol/L (6.6~21.30 mmol/L), the average serum Cr was 187.3μmol/L (97.5~286.6 μmol/L), the average GFR evaluated by renal radionuclide imaging was 58.1 mL/min (37.8~79.2 mL/min),and upper urinary tract was unobstructed. Conclusion Upper urinary tract obstruction and renal function were ameliorated and improved in a short time by transurethral resection of ureteral orifice invaded by advanced prostate cancer which caused hydronephrosis.

Objective To discover new method studying renal deficiency and syndrome of blood stasis by gemellary research method.Methods Through clinical investigation of 300 instances of twins,we choice three twins,include mistress Yang from Qionglai city who is being later stage of older;mistress Yu from Chengdu city who is being presenium;mistress Lu from Beijing who is being Middle-age using five species of ovi-type appraisement methods,and syndrome-penthemeron investigation by blood stasis,stagnation of blood measuring scale,renal deficiency measuring scale,and eight principles measuring scale,in this text.Results(1)Get three family constellation graphs,which provide inspiration for syndrome-penthemeron studing.(2)Though investigating to three twins,we discover that this relative value of eight principles measuring scale has augmented tendency with time-lapse.3.There haven’t regularity from the stagnation of blood measuring scale and renal deficiency measuring scale.Conclusion Using gemellary research method to study Diabetes Mellitus is perfect.In spite of there haven’t ideal result,but it provid prospective thinking and suggestion for us.

OBJECTIVETo study pathogeny, diagnosis and treatment of ureter fistula after renal transplantation.

METHODSThe clinical data from 30 cases after renal transplantations were analyzed.

RESULTSFour patients received conservative treatment, and 2 repairment of the fistula. Eleven patients had resection of the ureter or adjustment of the kidney, followed by the anastomosis of the ureter and bladder again. After the turning of the bladder's lamella, 13 patients were given 20 - 24 Foley's tube connecting the pelvis and bladder and nine of them were not subjected to re-anastomosis waiting for the pelvis crawling to the bladder as a tunnel. The one-year survival rates for 30 cases and kidneys was 96.7% (29/30) and 86.7% (26/30) respectively.

CONCLUSIONSThere a lot of causes for ureter which are fistula, running related to every aspect of transplantation. Early diagnosis and treatment is important to prognosis. Most patients need reanastomosis. According to the blood stream, edema, length of the ureter, operative procedures are selected to ensure free of strain.

Objective To investigate the effect of lentivirus carrying shRNA-VDR vector on GLi1 in pros-tate cancer PC-3 cells. Methods The cells were cultured according to the culture conditions of PC-3 cells. Expression of VDR and GLi1 in PC-3 cells was detected by fluorescence quantitative PCR and immunocytochemistry SP method.The efficiency of PC-3 cell virus infection was evaluated.The effect of VDR gene interference and GLi1 transcription level on PC-3 cells was detected by RT-PCR.Results Cell culture,cell status was recorded and PC-3 cells were in good condition and the passages was 4 days. Fluorescence quantitative and immunocytochemi-cal SP showed that VDR and GLi1 were expressed in PC-3 cells.The virus infection efficiency showed that the in-fection efficiency was about 95% when adding LV3-NC lentivirus to PC-3 cells at 1:10 ratio. RT-PCR showed that VDR-shRNA lentivirus successfully disturbed VDR expression and decreased by 85%(P < 0.05)compared with the control group after 72 days of VDR-shRNA lentivirus transfection. Transcription level of GLi1 gene in the experimental group increased by 9% compared with the control group(P < 0.05). The transcription level of GLi1 gene in the experimental group increased by 248% compared with the control group(P < 0.05). Conclusion The cultured PC-3 cells were in good condition. VDR and GLi1 genes were expressed in PC-3 cells. Lentivirus showed highest efficiency in infecting PC-3 at 1:10 ratio. When VDR was disturbed,the expression of GLi1 in-creased.In prostate cancer cells,vitamin D can inhibit the Hh signaling pathway and cause GLi1 expression down expression.
