Objective To establish the method and assess the safety，feasibility and clinical efficacies of percutaneous transhepaticcontrast-enhancedcholangio-ultrasonography(PTCECUS).Methods Twenty-one patients aged(58.5±16.65)years(range 27-93)with biliary obstruction or stricture underwent percutaneous transhepatic cholangiodrainage or ch01ecystodrainage.A dose of more than 50 ml of 0.94% Sono Vue(Bracco，Itay)solution was injected into their bile ducts(n=17)and cholecysts(n=4)through the drainage catheter.Their biliary tracts，cholecysts and duodenums were scanned under contrast pulsed sequencing mode(CPS，Sequoia 512，Siemens)to achieve related contrast-enhanced ultrasonograms.Severity of biliary obstruction were assessed according to the PTCECUS findingswith a comparison toconventionalultrasonography(CVUS)，magnetic resonance cholangiopancreatography(MRCP)and percutaneous transhepatic cholangiography(PTC)in a part of the patients.Results①PTCECUS gave rise to good-quality contrast-enhanced uhrasonograms of biliary tracts.②PTCECUS was superior to CVUS and in consistence with MRCP and PTC in evaluating the severity of biliary tract obstruction.This method helped to make a proper design for biliary drainage.③PTCECUS was more efficient than PTC in that PTC had the patients receive transhepatic puncture and cholangiography in separated departments.④Neither any complications immediate from transhepatic puncture and administration of SonoVue inall the 21 patients，nor those 1 to 8 months late during ultrasound follow up in 14 patients were found.Conclusions PTCECUS，characterized in bettering the display of biliary tracts，especially the severity of obstruction of biliary tracts，is safe through the procedure and valuable in supervising biliary drainage against obstructive jaundice.

Objective To study the MRI findings of HE and the pathological mechanism and to improve the diagnosis and differential diagnosis of HE. Methods Five patients of HE diagnosed by clinical and laboratory examination were examined with conventional MRI scan. Additional DWI, MRA and enhancement MRI scan were performed on 3 patients in which abnormal findings was detected on the conventional MRI. The distribution of lesions and signal characteristics were analyzed. The ADC values of the lesions and of the contralateral non-lesion area were measured. Moreover, the possible pathological mechanisms of HE were discussed on the basis of changes of clinical and imaging manifestations in the two cases with serial clinical and MRI data. Results Of 5 patients, brain abnormalities were found in 3 cases,which showed scattered spotted supratentorial white matter lesions of isointensity on T1 WI and DWI, and high signal intensity on T2WI and fluid-attenuated inversion recovery (FLAIR). Meanwhile, multiple plaque-like lesions involving both white matter and gray matter were found, mainly located at the basal ganglia nuclei, hippocampus and cingulate cortex. The lesions demonstrated iso-or hypo-intensity on T1 WI,and iso-or hyper-intensity on T2 WI, FIAIR and DWI at the initial stage. No enhancement was found in these lesions and MRA disclosed no remarkable findings. The ADC value of the lesions [ (0. 449 ± 0. 092) ×10-3 mm2/s] was decreased significantly compared with the contralateral noninvolved area [ (0. 838 ±0. 062) × 10-3 mm2/s] at the early onset. In 2 cases with glucocorticoid therapy, together with symptom relief, MRI follow-up scan demonstrated the reduction of lesion volume, the signal change to hyperintensity on T1 WI and hypo-intensity on DWL The ADC of the lesions increased significantly. Conclusion The MRI could be one of the effective tools for diagnosis, differential diagnosis, and judging the prognosis and therapeutic results of HE. Meanwhile, it may be a non-invasive method to study the pathological mechanism of HE.

The zinc finger protein A20 exists in many kinds of ceils in the body and plays multiple roles in physiological and pathological processes such as regulation of immune response,inflammatory diseases and cancers by inhibiting cell apoptosis induced by tumor necrosis factor (TNF) and restricting NFKB signaling pathway.Recently,the role of A20 in generation and development of tumors draws wide attention,hence,we summarized recent research progress of the relation between A20 and cancer in this review.

Objective To study the curative effect of mesenchymal stem cells(MSC)transplantation on occupational chronic benzene poisoning and summarize the nursing measures.Methods The clinical data of 5 patients with occupational chronic benzene poisoning treated with MSC transplantation for 48 times totally were retrospectively reviewed for the purpose of investigating the curative effects and summing up the nursing measures.Results After transplantation,the levels of white blood cells,hemoglobin and neutrophil,platelet were all increased significantly.The differences in white blood cells and neutrophil were significant between pre-and post-transplantation(P<0.05).Bone marrow hyperplasia was active after treatment.No adverse reactions were observed in all of the patients.Conclusion MSC is safe and effective in treating occupational chronic benzene poisoning.Observing patient’s conditions closely,implementing protective isolation and psychological nursing strictly and doing predictive nursing measures are of significance for success of MSC transplantation and improvement of the curative effect.

Objective: To explore the effect of different selenium sources on the function of humoral immunity and antioxidant capacity of rabbits. Method: Thirty-five rabbits were randomly divided into seven groups and vaccinated with rabbit haemorrhagic disease (RHD) dead vaccine. At the same time, rabbits were injected respectively with sodium selenite (0.1 mg/kg bw and 0.3 mg/kg bw), Kappa-selenocanageenan (0.1 mg/kgbw and 0.3 mg/kg bw), DL-selenomethionine (0.1 mg/kg bw and 0.3 mg/kg bw) and physiological saline as control. Antibody against RHD, activity of GSH-Px and content of MDA in rabbit serum were detected on 0, 10, 20, 30d after inoculation. Results: Sodium selenite (0.1 mg/kg bw), Kappa- selenocanageenan (0.3 mg/kg), and DL-selenomethionine (0.3mg/kg bw) could significantly increase the level of RHD antibody. Sodium selenite (0.3 mg/kg bw) and Kappa-selenocanageenan (0.3mg/kg bw) improved the activity of GSH-Px. All selenium groups could decrease serum MDA, but Kappa-selenocanageenan (0.3 mg/kg bw) showed the best effect. Conclusion: Kappa-selenocanageenan (0.3 mg/kg bw) was better than the lower dosage and other selenium sources in the effects on the function in humoral immunity and antioxidant capacity of rabbits.

BACKGROUND:Compared with the cone stem,short stem holds good matching with femoral canal,and remarkably reduces the risk of prosthesis loosening.OBJECTIVE:To further investigate the clinical efficacy of Accolade Ⅱ stem for Crowe type Ⅰ developmental dysplasia of the hip.METHODS:Clinical data of 16 patients with Crowe type Ⅰ developmental dysplasia of the hip undergoing total hip arthroplasty using Accolade Ⅱ stem were collected,the length of both lower limbs before and after surgery was compared,and the Visual Analogue Scale,functional recovery of the hip and general conditions were observed at 12 weeks postoperatively.RESULTS AND CONCLUSION:(1) The change in length of both lower limbs before and after surgery had significant difference (P ＜ 0.05),and 10 patients (62％) with the same length of both lower limbs before surgery,and 15 cases (94％) after surgery.(2) The postoperative acetablar abducent angle was 41°-54° (average 46.9°).(3) The Visual Analogue Scale and Harris hip scores after surgery were significantly improved compared with baseline (P ＜ 0.05).(4) The intraoperative blood loss was 147 mL on average,the mean operation time was 72 minutes,and the hospitalization time was 7.2 days.(5) All patients recovered well and no complications occurred at 3 months postoperatively.(6) To conclude,Accolade Ⅱ stem is safe and reliable for Crowe type Ⅰ developmental dysplasia of the hip,and exhibits good functional recovery of the hip.
