Objective To study a new method of opening prostatectomy.Methods 71 cases of benign prostatic hyperplasia (BPH) patients were divided into three group at random;treating group:prostatectomy by transfixing inferior vesical artery and reserving posterior urethra(n=21),control group Ⅰ:Millin operation(n=18) and control group Ⅱ:cystoprostatectomy through superior pectineus(n=32),the clinical effect was studied and observated.Results All 71 cases of patients were BPH according to pathology reports.Treating group had lower incidence than that of control group in injury of urethra,bleeding after operation,the times of irrigation of urinary bladder,urinary incontinence in the near future,secondary bleeding,urinary tract infection,bladder spasm,urethral stricture,and so on.Conclusions Prostatectomy by transfixing inferior vesical artery and reserving posterior urethra has many virtues such as simple,soon to discharge,cheapness of medical cost,and easy to spread.

Objective To investigate the effect,safety,and skills of holmium laser lithotripsy by ureteroscopy for upper urinary tract radiotransparent calculi complicated with polyps. Methods From January to December 2008,60 patients with upper urinary tract radiotransparent calculi complicated with polyps were treated by holmium laser lithotripsy(Coherent PowerSuite 20 W,500 ?m) via a ureteroscope.The laser lithotrite was introduced to the stones,and the intraluminal stone was fragmented and melted by holmium laser simultaneously.Results The mean operation time of this series was 21 min(15-70 min).The polyps was removed completely in one session in all of the cases except in 4 patients,whose upper calculi were flushed into the renal pelvis.No ureteral mucosa avulsion,perforation,false passage and other severe complications occurred.Some of the patients had mild haematuria after the operation without fever or renal pain.The patients were followed up for 3 to 12 months(mean 5 months);none of them had residual stones or ureteral stricture during the period. Conclusions Holmium laser lithotripsy via ureteroscope is a safe and effective procedure for the treatment of upper urinary tract radiotransparent complicated with polyps.

To investigate the effects of anti-sense peptide nucleic acids (PNAs) targeting Ki-67 gene on modulation of the proliferation and apoptosis of human renal carcinoma cell lines, human renal carcinoma cell line 786-0 cells were treated with anti-sense PNAs at different concentrations (1.0 micromol/L, 2.0 micromol/L, 10.0 micromol/L). The Ki-67 expression of 786-0 cells was detected by immunohistochemical technique and Western blot method respectively. The proliferation of 786-0 cells was studied by cell growth curves and 3H-thymidine incorporation. The apoptosis of 786-0 cells was detected by TUNEL assay. The control groups were treated with anti-sense oligonucleotide (ASODNs) targeting Ki-67 gene. Our results showed that the Ki-67 expression of 786-0 cells treated with anti-sense PNAs (16.9+/-0.7) was significantly inhibited as compared with that of the control groups (28.6+/-0.4) (P<0.01). The Ki-67 protein rate of 786-0 cells treated with anti-sense PNAs (42.1 +/-2.2) was significantly reduced when compared with that of the control groups (83.6+/- 1.4) (P<0.01). Proliferation of 786-0 cells treated with anti-sense PNAs (20.7+/- 1.5) was significantly inhibited as compared with that of the control groups (58.6+/- 1.4) (P<0.01). The apoptosis rate of 786-0 cells treated with anti-sense PNAs (28.7+/- 2.3) was significantly increased higher compared with that of the control groups (13.8 +/- 1.0) (P<0.01). From these finds we are led to conclude that anti-sense PNAs targeting Ki-67 gene have stronger effects on the inhibition of the proliferation and induction of apoptosis of human renal carcinoma cells than ASODNs targeting Ki-67 gene. The strategies using anti-sense PNAs targeting Ki-67 gene may be a promising approach for the treatment of renal cell carcinoma.

Objective To explore the effects of Tongfu Huayu Daotan Decoction (通化阏导痰汤)on the serum concentration of S-100β protein, neuron-specific enolase(NSE) and Prognosis in patients with severe craniocerebral injury.Methods Sixty patients with severe craniocerebral injury were randomly divided into a a'eatment group and a control group.The treated group was treated with Tongfu Huayu Daotan Decoction plus conventional treatments including dehydration,antibiotics, organ functional support, nerve nutrition, prevention of complication, etc.; the control group was treated with conventional treatments alone. The concentration of serum S-100β protein and neuron-specific enolase(NSE) in plasma at admission and at24, 36, 72huors, and 5, 7 days after treatment were determined respectively; the Glasgow outcome scale (GOS)and neurological deficits scoring at 2weeks and 4weeks after hospitalization were compared to observe the efficacy of the patients. Results The concentration of serum S-100β protein and neuron-specific enolase (NSE) in plasma at previous treatment and at 24, 36 hours after the treatment had no statistical difference in the two groups(P＞0.05 ), The concentration of serum S-100β protein and neuron-specific enolase (NSE) in plasma at 72huors, 5 and 7 days after the treatment in the Tongfu Huayu Daotan Decoction group were lower than those in the control group, the differences being significant (P＜0.01). The Glasgow outcome scale (GOS) and neurological deficits scoring at 2weeks and 4weeks after the treatment in the Tongfu Huayu Daotan Decoction group were significantly nigher than those in the control group, the differences being significant (P＜0.01) .Conclusion Tongfu Huayu Daotan Decoction can alleviate the plasma concentrations of S-100β protein and neuron-specific enolase (NSE) in patients with severe craniocerebral injury and markedly improve the clinical therapeutic effects. Combined Tongfu Huayu Daotan Decoction and western medicine can significantly reduce mortality and improve the Glasgow outcome scale (GOS), neurological deficits scoring and therapeutic effect.

Objective To evaluate the efficacy of standard large trauma craniectomy to treat the patients with severe bump brain injury. Methods Thirty-two bump brain injured patients with cerebral hernia were treated with inside and outside decompression of standard large trauma craniectomy compared with 24 cases of routine temporoparietal craniectomy between Oct 2001 and Aug 2004.Results In standard large trauma craniectomy group,21 cases got good recovery(65.6%) and 5 were dead(15.6%).In routine temporoparietal craniectomy group,9 cases got good recovery(37.5%) and 10 were dead(41.7%).There was significant difference between the two groups in good recovery and mortality(P

Objective:To investigate the anti-tumor immune responses against renal cell carcinoma induced by dendritic cells(DCs)transfected with survivin gene mediated by recombinant adenovirus.Methods:The DCs derived from human peripheral blood were infected with recombined adenovirus vector carrying the survivin gene.The expression of survivin protein in the infected DCs was examined by Western blotting assay;the surface expression of CD83,MHCⅡ,CD80 and CD86 by flow cytometry(FCM),Interleukin-12(IL-12)in the supernatants of DCs and IFN-? released by the cytotoxic T lymphocytes(CTLs)by ELISA,the ability of DCs in proliferating allo-lymphocytes by mixed lymphocyte reaction(MLR),and specific killing activity of CTLs by MTT assay.Results:The DCs presented mature DCs phenotype after transfection with Ad-svv.The expression of survivin protein in transfected DCs was confirmed by Western blotting analysis.The IL-12 level in the supernatant of DCs transfected with Ad-svv was significantly higher than that transfected with empty vector(Ad-CMV,P
