Objective To study a new operative method for treatment of hepatic venous occlasion without (associated) pathologic change of inferior vena cava or long-segment stricture. Methods A total of 44 cases of Budd-chiari syndrome with hepatic venous occlusion without pathologic change or long-segment stricture of (inferior) vena cava underwent combined mesocaval C-shunt, ligation of splenic artery, and esophagogastric (devascularization).Results Pre-shunt portal venous pressure was 36cmH2O(31~45 cmH2O, 1cmH2O=0.0098kPa) and post-shunt pressure fell to 26 cmH2O(21~33 cmH2O),the mean reduction was 10 cmH2O. One patient died of liver failure. A slight degree of hepatic encephalopathy occurred in 2patients who recovered after conservative treatment.Chylorrhea occurred in 4 patients, and it spontaneously disappeared 7d to 3.5months after operation. 39 patients(88.6% follow up) were followed up for 6months to 7years , and there was no case of recurrent bleeding nor hepatic encephalopathy. Ascites disappeared in 31cases,and was markedly reduced in 7 cases .The prosthetic grafts were patent as shown by color Doppler ultra sound in all followed-up patients.Conclusions This operation is simple and effective for B-CS with hepatic venous (occlusion) but not associated with inferior vena caval pathologic change or long-segment stricture.

protrusion measured by ultrasound for diagnosing bladder outlet obstruction.Methods A literature search of medline (1966.1-2011.6),embase(1984.1-2011.6),CNKI (1994.1-2011.6) and WEIPU Data (1989.1-2011.6) from 1999 to 2009 was performed by two reviewers independently.QUADAS items was applicated to assess trial quality.Golden standard was BOOI measured by urodynamics (BOOI more than 40 indicates bladder outlet obstruction).Heterogenous studies and meta-analysis were conducted by Meta-Disc 1.4 software.Results Totally 6 studies was included at last,involving 682 subjects.No threshold effect was found,but there was heterogeneity due to other factors.The meta-analysis showed that the sensitivity was 70.8 ％,specificity was 87.6 ％,positive LR was 5.132,negative LR was 0.303,the diagnostic OR was 22.18,the area under SROC curve was 0.8723 and Q index was 0.8028.Conclusions Intravesical prostatic protrusion measured by ultrasound is a good index for diagnosing bladder outlet obstruction in patients with benign prostate hyperplasia when intravesical prostatic protrusion is equal or more than 10mm.

To elucidate the effects of Zearalenone(ZEA) on proliferation and cell cycle of cultured thymic epithelial cells in mice,trypan blue staining and flow cytometric analysis were performed.At the concentrations from 1 to 25 mg/L,ZEA displayed a significant inhibitory action to proliferation of thymic epithelial cells in its dose-and timedependent manner.Higher doses(10-25 rag/L)ZEA could induce a profound increase in G2/M phase with arrest of thymic epithelial cells in the G2/M phase in a dose-dependent manner.In conclusion,ZEA could be assumed that there were toxic effects on the thymie epithelial cells of mice in vitro.

Objective To evaluate the value of preoperative ultrasonographic parameters in predicting the outcome of TURP.Methods A total of 202 patients with symptomatic benign prostatic hyperplasia (sBPH) entering our department for surgical therapy were prospectively recruited,with mean age of (65.5 ± 8.1) years,international prostate symptom score (IPSS) of 16.6 ± 8.1 and quality of life (QOL) score of 5 (3,6).Preoperative combined test of ultrasonography and urodynamics has found total prostate volume (TPV),transitional zone volume (TZV),transitional zone index (TZI),intravesical prostatic protrusion (IPP),resistive index (RI),postvoiding residue (PVR),detrusor wall index (DWT),ultrasonic estimation of bladder weight (UEBW) and maximum flow rate (Qmax) to be (75.0 ±38.5) ml,(49.9 ± 32.4) ml,0.59 ±0.14,(17.2 ±5.0) mm,0.63 ±0.12,(132.7 ±97.8)ml,(16.3 ±7.9)mm,(44.8 ± 7.1)g and (6.1 ± 6.0)ml/s respectively.A 6-monthsfollow-up after standard TURP were applied including re-measurement of IPSS,QOL score and Qmax.The patients were classified into 2 groups of effective and ineffective after the recovery being stratified into 4 levels of none,fair,good and excellent.The influence of preoperative ultrasonographic parameters on surgical outcome was analyzed by logistic regression and receiver operating characteristic (ROC) curve.Results The group of effective has 149 patients,with the preoperative TZI,IPP,RI,DWT and UEBW of 0.65 ± 0.27,(18.3 ± 3.1) mm,0.77 ± 0.18,(19.0 ± 5.0) mm and (46.6 ± 7.1) g,which were significantly higher than that of the group of ineffective (P ＜ 0.05) Lower RI,DWT and UEBW were found to be risk factors of unfavorable surgical efficacy (P ＜ 0.05) from multivariable analysis.The area under curve (AUC) of RI,DWT and UEBW in outcome prediction was 0.816,0.732 and 0.723 respectively from ROC curve,indicating the good predictive value of the 3 parameters with combined positive predictive value (PPV) of 96.3％.Conclusion RI,DWT and UEBW have favorable value in predicting TURP outcome.Measuring these parameters by preoperative ultrasonography might aid in determining the need for surgical intervention in sBPH patients.

PURPOSE: The aim of this research was to assess the value of the transitional zone index (TZI) and intravesical prostatic protrusion (IPP) from transrectal ultrasonography in evaluating the severity and progression of disease by analyzing the relationship between the 2 parameters and symptoms, clinical history, and urodynamics in benign prostatic hyperplasia (BPH) patients undergoing different treatment. MATERIALS AND METHODS: A total of 203 patients receiving medication and 162 patients who underwent transurethral resection of the prostate because of BPH were enrolled in this retrospective analysis. The clinical history and subjective and objective examination results of all patients were recorded and compared after being classified by TZI and IPP level. Linear regression was used to find correlations between IPP, TZI, and urodynamics. RESULTS: The 2 parameters were found to differ significantly between patients receiving medication and patients undergoing surgical therapy (p<0.05). PSA, maximum flow rate (Qmax), detrusor pressure at Qmax (PdetQmax), and the bladder outlet obstruction index (BOOI) differed according to various TZI levels (p<0.05). In addition, the voiding symptom score, Qmax, and BOOI of subgroups with various IPP levels were also significantly different (p<0.05). Both TZI and IPP had significant effects on Qmax, BOOI, and PdetQmax (p<0.05) and the incidence of acute urinary retention (p=0.000). CONCLUSIONS: The results demonstrated that both TZI and IPP had favorable value for assessing severity and progression in patients with BPH. Further studies are needed to confirm whether the two parameters have predictive value in the efficacy of BPH treatment and could be considered as factors in the selection of therapy.
