Abstract：

Objective To explore the effect of doxazosin on rabbit bladder compliance after partial bladder outlet obstruction. Methods A total of 40 male New Zealand white rabbits were randomized into 4 groups, with 10 rabbits in each group. Partial bladder outlet obstruction was established in groups B and C, while groups A and D underwent the same operation but without partial bladder outlet obstruction. On the day after the operation, groups C and D received oral administration of doxazosin. After 14 weeks, urodynamic examinations were carried out in all groups, and the bladder was weighted after cystectomy. Results Bladder weight was (3.2±0.9) g in group A, (14.1±2.3) g in group B, (5.0±2.0) in group C,and (2.9±0.5) g in group D. The bladder weight in groups B and C increased significantly compared to groups A and D (P＜0.01), group B increased significantly over group C (P＜0.01), and there was no significant difference between groups A and D (P＞0.05).The detrusor leak point pressure was (10.2±2.5) cm H2O in group A, (18.8±6.1) cm H2O in group B, (13.5±4.7) cm H2O in group C,and (11.6±3.6) cm H2O in group D. The detrusor leak point pressure in group B was significantly higher than group A, group D (P＜0.01) and group C (P＜0.05). There was no significant difference between group A, group C and group D (P＞0.05). The bladder compliance was (2.86±0.56) ml/cm H2O in group A, (1.22±0.39) ml/cm H2O in group B, (4.25±2.19) ml/cm H2O in group C,and (2.90±0.53) ml/cm H2O in group D. The bladder compliance was significantly decreased in group B compared to groups A and D (P＜0.01). Bladder compliance in group C was significantly higher than in groups A and D (P＜0.05), and there was no significant difference between group A and group D (P＞0.05). Conclusion Early use of doxazosin can delay the occurrence of lower bladder compliance after partial bladder outlet obstruction, thus protecting the storage function of bladder.     

The effects of topical L-arginine and Ng-nitro-L-arginine methyl ester after experimental acute spinal cord injury. A light and electron microscopic study

The primary objective of this study was to investigate the effects of topical L-arginine and Ng-nitro-L-arginine methyl ester vs the role of ischemia in contributing to secondary injury after experimental acute spinal cord trauma. Twenty-six rabbits were submitted to spinal cord compression at the T7/8 level. The animals were divided into three groups: no applied drug (n=6), L-arginine (n=10), and Ng-nitro-L-arginine methyl ester (n=10). L-arginine was topically administered at a dose of 10 μmol (1.742 mg) per kg immediately after acute spinal cord injury. Ng-nitro-L-arginine methyl ester was applied topically at a dose of 10 μmol (10 mg/kg) immediately after acute spinal cord injury. Cortical somatosensory evoked potentials were recorded before injury and 1 min, 15 min, 30 min, and 60 min after injury. Physiological parameters were followed before, during, and 1 h post injury. Light and electron microscopic analysis was performed in all of the groups. In contrast to group 1, the edema of perineural, axoplasm, or surrounding tissue, the thickening of walls of the arterioles and venules, and the degeneration in myelinated axons in groups 2 and 3 were well observed. However, no differences between group 2 and group 3 occurred. Electronic Publication

Abstract：

Objective To investigate the effects of solifenacin on the detrusor instability of patients with overactive bladder (OAB).Methods A total of 20 outpatients with OAB of.1 - 20 ( mean, 8 )years, 12 males and 8 females, aged 21 - 83 ( mean, 43) years were included in this study.Five mg solifenacin was given orally once daily for 12 weeks.Before and after treatment, overactive bladder symptom score (OABSS), patient perception of bladder condition symptoms rating scale (PPBC), and filling cystometry was performed.Results Before and after solifenacin administration, significant decrease were detected in term of unstable detrusor waves ( 2.3 ± 2.4) vs (0.6 ± 1.3 ) ( P ＜ 0.05 ), and detrusor overactivity ( DO ) disappeared in 6 patients.Bladder capacities at first desire to void and maximum bladder capacity were significantly increased (P ＜0.01 ).Bladder compliance and detrusor pressure at maximum urine flow had no significant difference (P ＞ 0.05 ).All patients had significant improvement in OAB symptoms evaluating by OABSS and PPBC ( P ＜ 0.05 ).Six patients had mild side effect of dry mouth and could be relieved by drinking more water.Conclusion Urodynamically, solifenacin decreases the detrusor overactivity, increases the bladder capacity and improves the quality of life of OAB patients.     

Acute phase effects of ATP-MgCl<Subscript>2</Subscript> on experimental spinal cord injury

The purpose of this study was to study the acute phase effects of adenosine triphosphate (ATP)-MgCl₂ on experimental spinal cord clip compression injury. Spinal cord clip compression injury was performed on 36 albino Wistar rats. The rats were divided into five groups. T4–T8 total laminectomy was performed on all rats. Group 1: sham-operated group. Group 2: clip compression group. In group 3, ATP-MgCl₂ (100 μmol/kg) was given 2 min before the "clip compression injury." In group 4, ATP-MgCl₂ (100 μmol/kg) was given 5 min after the clip compression injury. In group 5, ATP MgC1₂ (100 μmol/kg) was administered 8 h after the injury. The spinal cords were excised for a length of 2 cm and deep frozen at –76°C. Tissue malondialdehyde (MDA) levels were used to determine the effects of ATP-MgCl₂ on spinal cord lipid peroxidation. In the groups in which ATP MgCl₂ was administered after the clip compression injury (groups 4 and 5), the decrease in spinal cord MDA levels was statistically significant when compared with those of the injury group (group 2). Although MDA levels of group 4 were lower than those of group 5, this difference was not statistically significant. Administration of the ATP-MgCl₂ before the clip compression injury (in group 3) did not have a statistically significant effect on lipid peroxidation when compared with the injury group (group 2). In this study, we found that ATP-MgCl₂ has decreased lipid peroxidation in spinal cord injury and protected the spinal cord from secondary injury after the trauma. We concluded that ATP-MgCl₂ may be used in the treatment of spinal cord injuries in conjunction with the other treatment modalities, but further investigations are mandatory.

Abstract：

Objective To study the value of the preoperative detrusor contractility to the outcome assessment of prostatectomy for benign prostatic hyperplasia (BPH).Methods A total of 109 patients with BPH were analyzed.Their ages ranged from 62 to 83 years with a mean of 71 years.All patients underwent urodynamic study to confirm a diagnosis of BOO preoperatively.Further more, their BOO was not caused by nervous, endocrine or other diseases.Pateints were divided into two groups based on maximum detrusor contractility.Group Ⅰ (n =61, BPH with maximum detrusor contractility ≥ 40 cm H2O, 1cm H2O =0.098 kPa) underwent TURP or open surgery, respectively.Group Ⅱ (n =48, BPH with maximum detrusor contractility ≤ 20 cm H2O ) underwent TURP and suprapubic punctural cystostomy simultaneously,the bladder fistula was kept open continuously for at least two weeks postoperatively.The difference in outcome between the two grous was assessed by using urodynamic parameters including maximum detrusor contractility, Qmax and residual urine at one and three months postoperatively respectively.Student's t-test was used to compare the result for normally distributed data and Wilcoxon's signed-ranks test for skewed data in this study.Results There was significant difference in preoperative maximum contractility, Qmax between group Ⅰand groupⅡ (78.4 ±37.0 cm H2O) vs (19.2 ±5.4 cm H2O)(P＜0.01), (7.6±2.2 ml/s) vs (2.5 ± 1.1 ) ml/s (P ＜ 0.05) respectively.Although there was significant difference at one month postoperatively in Qmax (17.4 ±2.9)ml/s vs (12.5 ±2.0)ml/s (P＜0.05), no significant difference was found in Qmax between the two groups after three months ( 18.3 ±2.8 ml/s) vs ( 15.2 ± 1.8)ml/s (P ＞ 0.05).Conclusions The Qmax may improve and the impaired detrusor recovered gradually after the BOO was removed.Performing an operation on patients with BOO accompanied with detrusor underactivity may be useful to recover detrusor contractility.     

Influence of cryopreserved olfactory ensheathing cells transplantation on axonal regeneration in spinal cord ofadult rats

Objective: To observe the effects of cryopreserved olfactory ensheathing cells (OECs) transplantation on axonal regeneration and functional recovery following spinal cord injury in adult rats. Methods : Twenty-four rats were divided into experimental and control groups, each group having 12 rats. The spinal cord injury was established by transecting the spinal cord at T10 level with microsurgery scissors. OECs were purified from SD rat olfactory bulb and cultured in DMEM ( Dulbecco‘s minimum essential medium) and cryopreserved (-120~C) for two weeks. OECs suspension I (1-1.4) x 105/ul ] was transplanted into transected spinal cord, while the DMEM solution was injected instead in the control group. At 6 and 12 weeks after transplantation, the rats were evaluated with climbing test and MEP ( moter evoked potentials) monitoring. The samples of spinal cord were procured and studied with histological and immunohisto chemical stainings. Results: At 6 weeks after transplantation, all of the rats in both transplanted and control groups were paraplegic, and MEPs could not be recorded. Morphologyof transplanted OECs was normal, and OECs wereinterfused with host well. Axons could regrow into gap tissue between the spinal cords. Both OECs and regrown axons were immunoreactive for MBP. No regrown axons were found in the control group. At 12 weeks after transplantation, 2 rats (2/7) had lower extremities muscle contraction, 2 rats (2/7) had hip and/or knee active movement, and MEP of 5 rats (5/7) could be recorded in the calf in the transplantation group. None of the rats (7/7) in the control group had functional improvement, and none had MEPs recorded. In the transplanted group,histological and immunohistochemical methods showed the number of transplanted OECs reduced and some regrown axons had reached the end of transected spinal cord. However, no regrown axons could be seen except scar formation in the control group. Conclusions: Cryopreserved OECs could integrated with the host and promote regrowing axons across the transected spinal cord ends.     

Experimental study on spinal cord injury treated by embryonic spinal cord transplantation and greater omental transposition

Objective: To observe the clinical efficacy of the embryonic spinal cellular transplantation and greater omentaltranspesition for treatment of the spinal cord injury in 24 mongrel dogs. Methods: 24 adult mongrel dogs, weighing 10 ～ 13kg, without male and female limit, were employed in this experimental study and randomly divided into 4 groups:①simple injury group(group A) ;②greater omental transposition group (group B) ;③embryonic spinal cellular transplantation group (group C) ;④em-bryonic spinal cellular transplantation and greater omental transposition group (group D). Each group consisted of 6 dogs. SEP(somatosensory evoked potential) and MEP (motor evoked potential) of the spinal cord were examed prior to the spinal cord injuryand 2 months after the treatment to observe the changes of the animals‘ behavior. All dogs were killed 2 months after surgery andthe spinal cord sections were obtained from TI2 to LI level for pathological analysis and observation under the electron microscope.Re.lilts: There was an obvious difference in the spinal sematosensory evoked potential and the motor evoked potential between thegroup D.and the other three groups (group A, B, and C). Recovery of the behavior was noted. The spinal cells had survived fortwo months following the transplantation. Conclusion: Transplantation of the embryonic spinal cell and greater omentum for treat-ment of the spinal cord injury in dogs can gain a better outcome than the other groups in behavior and spinal somatosensory andmotor evoked potential, but the further study is still essential to confirm its clinical efficacy.     

老年男性下尿路症状伴逼尿肌过度活动患者临床及尿动力学特点分析

Objective To study the change of clinical and urodynamic parameters in the patients with lower urinary tract symptom (LUTS) caused by detrusor overactivity (DO). Methods Two hundred and twenty-seven patients with LUTS underwent clinical evaluation from October 2006 to December 2008, including Prostate Volume (PV), International Prostate Symptom Score (IPSS), Peak Flow rate (PF) and Residual Urine (RU) measurement. Pressure flow studies were performed. The detrusor overactivity was recorded to classify the patients into 2 groups, DO group and none DO group. The clinical and urodynamic parameters were compared between the two groups. Results Mean patient age was 70 years (range 52 to 89). According to the urodynamic results, there were 126 patients in DO group and 101 patients in none DO group. The mean patients age was older in DO group than the none DO group(P＜0.05). Adjusted by age, the PV, PF, and RU were no different between the two groups(P>0.05). The mean first sensation of bladder, bladder compliance, cystometric capacity, bladder outlet obstruction parameters, single voiding volume and max detrusor pressure during contraction were different between the two groups(P＜0.05). Conclusions The main risk factors of DO are the ageing and BOO. The non invasive parameters such as PV、 PF、 and RU could not be used to judge DO. The changes of urodynamic parameters caused by DO were hyperaesthesia of bladder、lower bladder compliance、 higher max detrusor pressure and lower max cystometric capacity. This study emphasis the importance of the urodynamic studies in the aged patients with LUTS.     

甲泼尼龙预干预脊髓缺血再灌注损伤对热休克蛋白27和肿瘤坏死因子α表达的影响

Objective To observe the effect of methylprednisolone (MP) pre-intervention on ex-pressions of heat shock protein 27 (HSP27) and tumor necrosis factor alpha (TNF-α) in cells in rat spinal cord following ischemia-reperfusion injury. Methods One hundred and fifty male Sprague-Dawley (SD) rats were randomly divided into 3 equal groups: group A (control) in which the abdominal aorta was exposed without any treatment, group B in which the abdominal aorta was clipped for 30 minutes before reperfusion for 3 bours to establish a model of ischemia- reperfusion injury, and group C in which intravenous MP injection was conducted 30 minutes before the establishment of the ischemia-reperfusion injury model. Three hours later the spinal cords were harvested. Pathological changes of spinal cord cells were observed with HE staining and expressions of HSP27 and TNF-α in spinal cord cells were observed with immunohistochemical staining. The motor function of hind-limbs before was evaluated before sample harvest. The data were analyzed with SPSS software. Results There were significant differences between groups A and B in the expressions of TNF-α and HSP27. Compared with group B, the expression of TNF-α decreased and HSP27 increased in group C, with statistically significant differences between the 2 groups. The motor function score of hind-limbs decreased in group B but improved in group C. Conclusions Since MP can decrease the expression of TNF-α and up-regulate the expression of HSP27, it has a potency of neuro-protection. Spinal cord ischemia-reperfusion injury can be avoided or decreased after MP pre-intervention.

目的 探讨良性前列腺增生(BPH)合并膀胱过度活动症(OAB)的尿动力学特点,为正确合理的治疗提供参考.方法 回顾性分析2009年1月至2010年5月就诊的235例BPH患者的尿动力学检查资料.患者年龄52～88岁,平均(68±8)岁.根据患者主诉有无OAB症状分为BPH组和BPH合并OAB组;根据尿动力学检查有无逼尿肌过度活动(DO)又将其分为单纯性BPH组、单纯性BPH合并DO组、BPH合并OAB无DO组及BPH合并OAB伴DO组,比较各组年龄、国际前列腺症状评分(IPSS)、前列腺体积、最大尿流率、残余尿量、初感容量、强烈尿感容量、梗阻指数和逼尿肌收缩力情况.结果 最终入选219例患者,年龄56～88岁,平均年龄(66±8)岁,平均前列腺体积(35±24)ml,平均最大尿流率(11±6)ml/s.33.8%(74/219)的患者尿动力学检查出现DO.与BPH组(104例)比较,BPH合并OAB组(115组)年龄更大、IPSS评分更高、前列腺体积更大、初感容量及强烈尿感容量更小、梗阻指数及逼尿肌收缩力减弱比例更高(P＜0.05).单纯BPH组、BPH合并DO组、BPH合并OAB无DO组及BPH合并OAB伴DO组分别为93例(42.5%)、11例(5.0%)、52例(23.7%)、63例(28.8%).BPH合并OAB伴DO与BPH合并DO两组比较,前者DO最大逼尿肌压更高、持续DO时间更长.结论 了解BPH合并OAB患者的尿动力学特点对于合理治疗和预测疗效具有重要意义.     

Urologic management of spinal cord injury by subarachnoid phenol block

Subarachnoid phenol block was applied to four traumatic spinal cord injury patients who had been suffering from urinary incontinence caused by detrusor hyperreflexia. Two were females with complete thoracic cord injury, the others were males with incomplete cervical cord injury. In all patients, detrusor hyperreflexia and urinary incontinence disappeared after 0.3-0.6 ml injection of 10% phenol glycerin. Vesicoureteral reflux observed in three ureters of two patients disappeared or improved. Two obtained sufficient bladder capacity for urine storage, while the others who had been treated by continuous urine drainage for a long time prior to the block could not obtain sufficient bladder compliance. The cause seemed to be organization of the bladder wall.
