ABSTRACT
Objective To explore the efficacy and safety of the resection of prostate-tangerine techniquewith 980 nm diode laser benign prostatic chyperplasia(BPH).Methods Data of 60 patients with highvloum BPH treated with the resection of prostate-tangerine technique with 980 nm diode laser were reviewed.The age of the patients were 65-89 years old,and mean prostate volume was 74.5± 13 ml.The mean operative time,blood loss were oberseved and recored,the international prostate symptom score(IPSS),quality of life score (QOL),maximum urinary flow rate(Qmax) and residual urine volume (PVR) were collected and analyzed.Results The 60 cases were safe during the perioperative period.The average operation time was (70.2± 16.9) min,and there was no obvious bleeding during the operation and no blood transfusion cases.The time of remove the transurethral catheter was 2-5 d,and the mean time was (2.4±0.3) d.Follow up 1-3 months after operation,a significant reduction in IPPS was reported (P =0.000),significant durable improvements in Qmax,PVR before operation(P=0.000).Conclusion Transurethral vaporization of 980 nm diode laser could be a safe and effective treatment modality for BPH.
ABSTRACT
ObjectiveTo explore the influence of mental abacus calculation (MAC) training on children's form recognition.Methods 28 children ( 14 children with MAC training and 14 children with non-MAC traning)were investigated by using event-related potential(ERP) technology.The event-related potentials were recorded when subjects were in the different form shape recognition.Results ( 1 ) The amplitudes of the posterior P1 evoked by the children with MAC training ( (9.59 ± 3.58) μV) were significantly greater than that of the children without MAC training ( (7.06 ± 2.84) μV) ( P ＜ 0.05 ).(2) The amplitudes of right temporal-posterior N170 of children with MAC( ( -9.83 ±2.97) μV) were markedly less than that of children with non-MAC( ( - 12.45 ±2.51 ) μV) ( P ＜ 0.05 ).( 3 ) The amplitudes of prefrontal P3 of children with MAC ( (7.65 ± 2.25 ) μV) were remarkably greater than that of children with non-MAC ( (4.89 ± 3.35 ) μV) ( P ＜ 0.05 ).ConclusionThe brain function of form recognition in children is influenced by mental abacus calculation training.
ABSTRACT
Objective To investigate the expressions of Livin protein and VEGF protein in bladder urothelial carcinoma(BUC) ,and theirs relationships with the clinicopathologic parameters of bladder urothelial carcinoma. Methods The expression of Livin and VEGF protein in 69 samples of BUC tissue and 10 samples of normal bladder epithelium tissue were detected by immunohistochemical SP method. Their relationships with clinicopathologic data were statistically analyzed. Results The positive expression rate of Livin and VEGF in BUC tissues were 65.2% (45/69) and 46.4% ( 32/69), but negative in normal bladder epithelium tissues, which showed significant differences in the comparison (Ps ＜ 0. 05 ). We found significant difference in the comparison of Livin positive rate between groups with or without recurrence ( 78. 8 % vs 48. 1%, χ2 = 6. 13, P ＜ 0. 05 ); but no differences in pathological grade,TNM stage and tumor number( Gl 55.6% ,G2 64. 3% ,G3 73.9% ;Ta ～ T1 61.9% ,T2 ～ T4 70. 4%; Single-tumor 59. 6%, multi-tumor 77.3%; χ2 = 1.52,0. 52,2.07, Ps ＞ 0. 05 ). For BUC,the expression of VEGF was correlated with the pathological grade,TNM stage( Gl 16. 7% ,G2 53.6% ,G3 60. 9%, χ2 = 8. 91; Ta ～ T1 33.3%, T2 ～ T4 66. 7%; χ2 = 7. 34; Ps ＜ 0. 05 ), but not the tumor number and recurrence( Single-tumor 57.4% , multi-tumor 59. 1%, χ2 = 0. 01; with recurrence 51.5% , without recurrence 40. 7% ,χ2= 0. 69; Ps ＞ 0. 05 ). We found no relationship between the expression of Livin and VEGF (r =0. 056,P ＞ 0. 05 ). Conclusion The overexpressions of Livin and VEGF protein may play an important role in the occurrence and development of BUC. Combind detection of these two protein can be used in the diagnosis and prognosis of BUC.
ABSTRACT
Objective To access the effect of intermittent catheterization (IC) on the urinary tract infection in patients with spinal cord injury. Methods Sixty patients of spinal cord injury combined with urinary tract infec-tion were randomly divided into two groups: treatment group (32 patients) treated with sensitive antibiotics and IC;control group (28 patients) treated with sensitive antibiotics only. Both groups were treated for two weeks. Results In the treatment and control group,the cure rate was 56% and 29% ,respectively,the total effective rate was 91% and 64% in the treatment and control group,respectively,the clearance rate of bacteria was 81% and 57% ,respec-tively. All differences were significant (P<0.05). Conclusions IC can improve the effect of antibiotic on urinary tract infection in patients with spinal cord injury, and might be effective on the treatment of urinary tract infection caused by various neurogenic bladders.
ABSTRACT
Objective To discuss the prognosis of the metastatic prostatic carcinoma and analyze the relative factors. Methods From 2001 to 2002, 32 cases of matastatic prostatic carcinoma were admitted to our hospital, the ages ranging from 54 to 87, with the mean age of 71 years. All the diagnosis was proved by the six cores transrectal biopsy of the prostate. The serum PSA ranged from 63 to 2000 ng/ml. Two cases had the Gleason score of 2 - 6, 19 cases had the Gleason score of 7 and 11 cases had the Gleason score of 8 - 10. Preoperative routine examinations included serum testosterone, pelvic CT or MRI scan, CXR and bone scan. Twenty-seven cases were found to have osseous metastasis, among them 8 cases combined with lymph nodes metastasis, and 5 cases with lymph nodes metastasis only. All of them were treated with gonadectomy and the blockade of the androgen receptor (with Bicalutamide 50 mg/d or Flutamide 250 mg/d). It lasted 7 - 48 months with first endocrine therapy,and mid last time 23 months. After first line endocrine therapy failure, Diethylstilbestrol and Estramustine were used in the androgen-independent stage. Thirteen cases were not effective, and second therapy had effect to 19 cases and it lasted for 3 - 15 months. Results The follow-up periods ranged from 13 to 98 months, with the mean period of 33 months. Twenty-eight cases died, 4 cases survived. The median survial period was 37 months, 1-year survival rate was 100% (32/32), 3-year survival rate was 53%(17/32) , 5-year survival rate was 19%(6/23). As to the survival period, there were negative correlaions between survival and the level of PSA (r= -0. 262, P=0. 045) and the Gl-eason score (r=- 0. 624, P=0. 001). There were positive correlations between survival and the level of testosterone (r=0. 514, P=0. 008) and the age (r=0. 311, P = 0. 032). And there was no correlation between survival and the number of the positive cores of the biopsy (r=0. 211, F = 0. 158) and the clinical stage (r=0. 211, P = 0. 352). Conclusions As to the metastatic prostatic carcinoma, there are correlations between the survival and the levels of testosterone before treatment, age, the Gl-eason score and the level of PSA. There is no relationship between the survival period of the metastatic prostatic carcinoma and the number of the positive cores of the biopsy and the clinical stage.
