OBJECTIVETo introduce a new procedure for repairing coronal or subcoronal hypospadias with severe chordee.

METHODSA modified technique of elongating the anterior urethra, combined with the MAGPI procedure, was used to repair the coronal or subcoronal hypospadias in 19 severe chordee patients (aged 5 to 12 years). The fibrous bands on the ventral aspect of the penis were excised to correct the chordee. If the penile curvature still remained, the corpora cavernosa dissection and elongation could be applied.

RESULTSAll of the patients were successfully treated by this procedure in one stage.

CONCLUSIONSThe modified technique of the anterior urethra elongation, combined with MAGPI procedure, might be one of the simple and effective method for repairing coronal or subcoronal hypospadias with severe chordee.

Objective To explore the effects of different treatments on prognosis of patients with Gynura segetum caused hepatic vein occlusion disease (HVOD).Methods From July 2008 to January 2016,85 patients with Gynura segetum caused HVOD were enrolled and received treatment of liver function protection and microcirculation improvement.According to different treatment options,patients were divided into non-anticoagulation group,nowanticoagulation transfered to transjugular intrahepatic portosystem stent-shunt (TIPS) group,anticoagulation group,anticoagulation transfered to TIPS group and anticoagulation-TIPS step-by-step treatment group.The efficacy of each group was observed.Chi square test was performed for statistical analysis.Results Among 22 patients who received nonanticoagulation treatment,six (27.3％) patients were cured and 14 (63.6％) patients died during the treatment period;besides two (9.1 ％) patients received TIPS because of ineffective treatment and achieved longterm survival.Among 63 patients treated with combination of low-molecular-weight heparin and warfarin,six (9.5％) patients died and 36(57.1％) patients were cured.The cure rate was higher than that of nonanticoagulation group (x2 =5.820,P=0.016).Other 21 patients received TIPS treatment,achieved longterm survival except one patient died from surgical complications.The cure rate of anticoagulation-TIPS step treatment group was 88.9 ％ (56/63) which was higher than that of non-anticoagulation group,and the difference was statistically significant (x2 =31.350,P＜0.01).Conclusions Compared to conventional liver function protection treatment and symptomatic treatment,anticoagulation therapy significantly increases the cure rate of patients with Gynura segetum caused HVOD.Anticoagulation-TIPS step-by-step treatment further improves the cure rate.

Aim Toinvestigatetheanalgesiceffectsof epidural osthole application on the mechanical allodyn-ia and the ERK/MAPK signaling pathway and the expression of COX-2 mRNA in the spinal dorsal horn.Methods 125adultmaleSDratswererandomizedin-to five groups( n=25 each) :Blank, Sham, NP, Ost and vehicle. At postoperative day 6, 1mg/rat osthole 50 μl was injected epidurally into group Ost and the same volume of vehicle was given into group vehicle. The mechanical pain threshold was measured by 50%MWT at 1 day before operation and the 3 rd,6 th,7 th, 14 th,21 st day after operation. After the measurement of pain threshold on postoperative day 14 , the L4-6 segment of spinal dorsal horn was removed for determi-nation of the expression of ERK, pERK and COX-2 mRNAbyWesternblotandRT-PCR.Results Com-pared with blank group, the mechanical pain threshold was only down-regulated at day 1 after operation in sham group, the expression of pERK and COX-2 mR-NA in sham group showed no significant difference ( P>0. 05 ); the mechanical pain threshold was signifi-cantly down-regulated after operation in NP, Ost and vehicle groups( P<0. 05 ) and the expression of pERK and COX-2 mRNA was significantly increased ( P <0. 05). Compared with vehicle group, the pain thresh-old in Ost group was significantly increased after drug administration( P<0. 05 ) and the expression of pERK and COX-2 mRNA was significantly reduced ( P <0. 05 ) . The expression of ERK showed no significant difference among each group(P>0. 05). The correla-tion analysis on pERK1/2 and COX-2 mRNA revealed the Pearson correlation coefficient was 0 . 878 and 0 . 910 , suggesting a strong positive correlation between pERKandCOX-2mRNA.Conclusions Ostholead-ministrated in the early stage after surgery can alleviate the nucleus pulposus-induced radicular inflammatory pain probably by inhibiting the expression of pERK and COX-2 mRNA in spinal dorsal horn.

Objective To investigate the type,clinical and imaging features of iatrogenic bile duct injury and the efficacy and safety of endoscopic and interventional radiology therapy.Methods A total of 48 patients with iatrogenic bile duct injury who have undergone endoscopic and/or interventional therapy from January 1st 2013 to June 30th 2016 were enrolled.Patients' general information,causes of injury,clinical manifestations,treatment methods,efficacy and complications were retrospectively analyzed.Results The causes of iatrogenic bile duct injury were cholecystectomy(45.8％,22/48),liver transplantation (35.4％,17/48),transjugular intrahepatic portosystemic shunt (8.3％,4/48),Roux-en-Y anastomosis (6.3％,3/48) and endoscopic retrograde cholangiopancreatography (4.2％,2/48).The most common type of iatrogenic bile duct injury was stenosis of intra/extra bile ducts (66.7％,32/48).Other types included biliary fistula(18.8％,9/48),hemobilia (10.4％,5/48) and stenosis of anastomotic stoma (4.2％,2/48).The most common clinical manifestations were jaundice (37.5％,18/48) and abdominal pain (29.2％,14/48).Other clinical manifestations were fever (14.6％,7/48),hematemesis or melena (8.3％,4/48) and abnormal drainage fluid (8.3％,4/48).Diagnosis was confirmed by angiography,cholangiography or endoscopy.The overall effective rate of minimally invasive therapy was 91.7％ (44/48) and the most common complications were fever (16.7％,8/48) and pancreatitis (10.4％,5/48).Other complications were hemobilia (2.1％,1/48),cardia dilaceration (2.1％,1/48) and biliary fistula caused by catheter shedding(2.1％,1/48).Conclusion Iatrogenic bile duct injury could occur after upper abdominal surgeries,endoscopic or interventional procedures.Early diagnosis and treatment with endoscopic or vascular interventional methods can achieve satisfying efficacy and safety.
