Objective To explore the surgical approach of reducing the incontinence after radical retropubic prostatectomy with recent anatomic findings. Methods Sixteen patients with stage B prostate carcinoma received continence preserving anatomic radical retropubic prostatectomy. Results All the patients were followed up 3 months to 5 years,mean 13 months.Thirteen patients had normal voiding,two with mild stress incontinence.Only one was complicated with serious incontinence. Conclusions Identifing and preserving the external striated urethral sphincter and its innervation in performing anatomic retropubic prostatectomy will achieve postoperative urinary continence.

Objective Focal nodular hyperplasia(FNH) is composed of multiple hyperplastic liver cell nodules,but its pathogenesis has not been elucidated. Foci (FAH) or nodules of altered hepatocytes (NAH) are precursors of hepatocellular adenoma (HCA) and carcinoma.This study aimed at identifying FAH and NAH from FNH and evaluating their role in FNH development.Methods 6 FNH lesions from 5 patients and 10 HCA from 9 patients were examined histologically,and expression levels of CD_(34) cytokeratin 19(CKl9) and Ki-67 antigen were demonstrated immunohistochemicailly.Proliferative activity was evaluated by Ki-67 antigen-labeling indices(Ki-67 LI).Results Multiple FAH and NAH were identified in all of the 6 FNH lesions. Whiie micmvasculatures were demonstrated by CD_(34) immunoreactivity in both HCA and FNH,their density and distribution were different in these two lesions,being diffuse in HCA and focal or nodular,mainly within NAH.CKl9 expression Was found in FNH,localized in ductal and ductular cells,but not within NAH and HCA.Average Ki.67 LI of 73 NAH(2.8%) was shown to be higher than that of the whole FNH lesions (0.6%),and had no statistieal difference comparable to that of HCA(1.8%).Conclusion Muhiple NAH are present in all classical FNH lesions.Unlike the surrounding parenchyma,NAH lesions are more proliferative and equipped with CD_(34)-positive microvasculatures as in HCA.

ObjectiveTo evaluate the efficacy and safety of combination therapy of tamsulosin and solifenacin for benign prostatic hyperplasia ( BPH ) with overactive bladder ( OAB ).Methods82 patients with OAB and coexisting BPH were randomly divided into tamsulosin group ( n = 38 ) and combination group ( n = 44). The ages were from 50 to 75 y ( averaged, 56.8 ± 8.6). Inclusion criteria: the mean frequency of micturition ≥8 times per day, the frequency of nocturia ≥2 times per day, voiding volume ＜200 ml each time; for the overactive bladder symptom score ( OA BSS), the 3 rd score ＞ 2, total score ＞ 3. The tamsulosin group accepted tamsulosin 0.2 mg once daily, the combination group accepted tansulouxin 0.2 mg and solifenacin 0.2 mg once daily. Both groups were maintained the corresponding therapy for 12 weeks.The international prostate symptom score (IPSS), Qmax, residual urine volume, OAB score and adverse reactions were recorded.ResultsThe values of IPSS ( 19.5 ±2.2 vs 15.6 ±2.4, P =0.027), the voiding symptom score ( 15.6 ± 2.4 vs 3.4 ± 1. 7, P = 0. 022) and Qmax ( 13.7 ± 3.8 vs 16.6 ± 4.1, P = 0. 034 )improved significantly after treatment in tamsulosin group ( P ＜ 0. 05 ). The values of IPSS ( 19.7 ± 2.3 vs 9.7 ± 3.0, P ＜0. 001), the storage symptom score (13.8 ± 1.9 vs 5.6 ± 1.6, P ＜0. 001 ), OABSS (10.3 ±1.8 vs 5.3 ±1.3, P ＜0.001) and Qmax(14.1 ±4.1 vs 17.2 ±3.5, P=0.027) also improved significantly after treatment in combination group ( P ＜ 0. 05 ). The values of IPSS ( 9.7 ± 3.0 vs 15.6 ±2.4, P ＜ 0.001 ), the storage symptom score (5.6 ± 1.6 vs 12.0 ± 1.6, P ＜ 0.001 ) and OABSS ( 5.3 ±1.3 vs 9.7 ± 2.7, P ＜ 0. 001 ) improved significantly in combination group than those in tamsulosin group ( P ＜0.001 ). There were no difference between two groups in values of the voiding symptom score, Qmax and residual urine volume ( P ＞ 0.05 ). The incidences of adverse reactions in tamsulosin group and combination group were 7.9％ (3/38) and 20.5％ (9/44) without significant difference. There was no acute urinary retention in both groups.ConclusionsIt is effective and safe for patients with BPH and OAB to accept combination therapy of tamsulosin and solifenacin.

Objective To discuss the management of renal vein trauma in the percutaneous ne-phrostomy (PCN) procedure.Methods Three cases with renal vein trauma by PCN or malposition of nephrostomic catheter were reviewed.Case 1 was a patient with staghorn calculi.There was mas-sive hemorrhage after the puncture and the dilatation during PCN.Then the nephrostomy catheter was clamped.The post-operative CT scan showed the nephrostomy catheter passed the inferior vena cava to the right external jugular vein.Case 2 was a patient with a 3 cm calculus in the inferior calice of the right kidney.A massive haemorrage occurred after the dilatation by the 16 F sheath guided by ultra-sound during PCN.The nephrostomic catheter was found in the renal vein by X-ray film.Case 3 was a patient with bilateral hydronephrosis complicating chronic renal failure,which caused by the meta-static of the gastric carcinoma.After the puncture,the massive hemorrage appeared and a nephros-tomic catheter was placed and then clamped.The catheter was seen in the renal vein confirmed by the X-ray.For all 3 patients,the catheter was withdrawn carefully monitored by the X-ray until the place of the renal vein perforation during the first 24-48h.Then it was withdrawn 3 to 4 cm each time un-til reach the pelvic.Results The hemorrhage was well controlled and nobody needed the surgical in-tervention.There was no renal function aggravation in these 3 patients.Conclusions The renal vein trauma during the echo-guide PCN procedure can be treated by clamping the nephrostomy catheter and withdrawing it gradually.Thus,the surgical intervention can be avoided and this method will not im-pair the renal function.

Objective:To observe the changes of metabolic intensity value of points on the face before and after needling bilateral Hegu (LI 4) in healthy people and provide scientific basis for association between Hegu (LI 4) and face/mouth. Methods:A total of 45 healthy college students were selected in this study. Using medical thermography and Pennes bio-heat transfer model, the infrared thermograph images on the face before and after needling bilateral Hegu (LI 4) were collected to observe the distribution of metabolic intensity value on the face before acupuncture and changes in these values after needling bilateral Hegu (LI 4). Results:Before acupuncture, Cuanzhu (BL 2) had the maximal metabolic intensity value. Its mean value was (0.71±0.23) W. Quanliao (SI 18) had the minimal metabolic intensity value. There were no left-right statistical significances in metabolic intensity values. After needling bilateral Hegu (LI 4), the metabolic intensity values of most points on the face were increased. Kouheliao (LI 19) obtained the maximal increase: 0.35 W on average; and Yangbai (GB 14) obtained the minimal increase: 0.08 W on average. Conclusion:Points on both sides in healthy people have good symmetry in metabolic intensity value. After needling bilateral Hegu (LI 4), the metabolic intensity values of points on the face were increased, especially points around the lips, which accords with the pathway of the Large Intestine Meridian on the head and face. This provided some scientific foundation for the association between Hegu (LI 4) and face/mouth.

A new type of surface plasmon resonance ( SPR) spectroscopy system was designed and built. Here, a kind of dual photocell sensor was developed as a detection device to achieve a rapid measurement of SPR angle within a certain range. This SPR system was combined and integrated with electrochemical workstation to obtain a new type of electrochemistry-time-resolved SPR ( EC-TR-SPR ) instrument via instrumental technique. This EC-TR-SPR instrument was used to characterize the electrochemical polymerization process of aniline to validate the spectroscopic characteristics. Applications of transient electrochemical characterization methods, including chronoamperometry and differential pulse voltammetry, confirmed the time resolution and the applicability of this instrument system toward the steady state and transient electrochemical methods upon small molecular reactions. The experiment results showed that this EC-TR-SPR possessed the time resolution up to 10000 times per second (0. 1 ms), and could be used to real-time investigate the doping and de-doping of polymerization process of aniline monomer as well as the prepared polyaniline film, which could not be discriminated on a conventional electrochemical current-time curve. .

Objective To discuss the feasibility and benefits of staged ureteroscopic laser lithotripsy in complicated cases. Methods From May 2005 to May 2008, the staged ureteroscopic procedure was done in 56 cases for ureteric stricture, kinking, spasm or high mobility of ureteric mucosa. Encountering difficulties, with the guide wire settled in place, the endoscopic procedure was ended and a ureteral stent was set. A second ureteroscopic procedure was carried out two weeks later. Results There was no difficulty for the insertion and the advancing of the ureteroscope two weeks later in all 56 cases. Among the 41 cases previously having the ureteric calculi, the stone was pushed into the kidney by the stent in 16 cases. There was no surgical complication during the second procedure. After three months the complete evacuation rate of the calculus was 96.4%. No patient experienced a fever >39.1 ℃ after the first attempt. Conclusions For complicated cases, such as ureteric stricture, spasm, kinking and high mobility of the ureteric mucosa which hinder the safe advancing of the ureteroscope, staged ureteroscopic procedure might be a safe and effective choice.
