Objective To investigate the diagnostic values of direct lymphangiography for the thoracic duct outlet obstruction.Methods The image data of direct lymphangiography were retrospectively analyzed in 124 patients with lymphedema,Chylothorax,chylous ascites,chyluria and intestinal lymphangiectasis,and compared with the results of neck thoracic duct surgical exploration,2 radiologists reviewed DLG DSA images in a double blind manner.The number of neck stem,subclavian stem,bronchialmediastinal stem and TD terminal into blood obstruction on the operation side showed by DLG were assessed using Kappa analysis.Results Of 124 patients,80 patients had the left cervical lymphatic stem reflux on DLG,75 patients with the left subclavian lymphatic stem reflux,30 patients with the left bronchial-mediastinal lymphatie stem reflux,118 patients showed the thoracic duct outlet barrier into the blood.The consistency rate of DLG were 89.9％ (80/89),92.6％ (75/81),90.9％ (30/33) and 95.2％ (118/124) compared with the neck thoracic duct surgical exploration.Tow radiologists had a high degree of diagnostic consistency (K =0.82,P ＜ 0.05).In addition,114 patients (91.9％) had tortuous,dilated waist lymphatic stem,only 10 patients (8.1％) were normal.The cisterna chyli reflux were found in 92 patients (74.2％),intestinal stem reflux in 16 patients (12.9％),reflux to the kidney area in 11 patients (8.9％),to the pericardium reflux in 5 patients (4.0％),vaginal lymphatic leakage in 7 patients (5.6％),retroperitoneal lymph leakage in 2 patients (1.6％),pleural lymphatic leakage in 3 patients (2.4％),tracheal lymph leakage in 1 patient (0.8％).Conclusion Direct lymphangiography has a high consistency with the cervical thoracic duct surgical exploration in displaying thoracic duct outlet obstruction.

Objective To detect the methylation status of the promoter of BNIP3 gene in gastric cancer cell lines MKN1,and to explore the mecha?nism of DNA methylation regulating the expression of BNIP3 in gastric cancer cells. Methods The methylation status of BNIP3 promoter was de?tected by bisulfate sequencing PCR. Reverse transcription PCR was used to evaluate BNIP3 mRNA expression. MKN1 cells were treated with 5?Aza?2′?deoxycytidine(5?Aza?CdR),and after the treatment,the methylation status and BNIP3 mRNA expression were observed. Chromatin immuno?precipitation(ChIP)was used to determine the combination of BNIP3 with DNA methyltransferase 1(DNMT1). Results The promoter DNA of BNIP3 in MKN1 cells was in state of hypermethylation. Compared to the control group,methylation status and mRNA expression of BNIP3 in the drug treatment group(the 5?Aza?CdR concentration was 10μmol/L)were reversed,which showed statistical differences(P<0.05). 5?Aza?CdR inhibited the combination of BNIP3 with DNMT1. Conclusion CpG island methylation regulates BNIP3 gene expression in MKN1 cells. DNA methylation is related with the binding between the promoter of BNIP3 and DNMT1.

Objective To explore the feasibility of transauricular arterial access for hepatic artery catheterization in rabbits.Methods Thirty healthy New Zealand White rabbits were randomly divided into 5 groups ( n =6 in each group):transauricular vein injection group , transarterial infusion group , transarterial lipiodol group , transarterial gelfoam group and transhepatic puncture group .Every rabbit was prescribed elemene (20 mg/kg) via different access in 6 minutes. All the rabbits of hepatic artery catheterization were divided into two groups according to their serial number :transauricular arterial access group (odd, n=9) and transfemoral arterial access group (even, n=9).The arterial access could be changed each other due to the failure of one technique .The catheterization time , success rate and survival rate were compared between the two groups .Venous blood collection via auricular vein or jugular vein for pharmacokinetics was performed in each rabbit .Results Technical success rates of hepatic artery catheterization were 0% ( 0/9 ) and 88.9%( 16/18 ) for transauricular and transfemoral arterial access , respectively . The time duration of transauricular and transfemoral access groups was 28.4 ±13.6 and 33.9 ±19.6 minutes, respectively (P>0.05).The survival rates of the transauricular and transfemoral access groups were 100%(9/9) and 88.9%(16/18), respectively.Blood samples were collected via auricular vein in 4 and jugular vein in 23 rabbits.Conclusions Hepatic artery catheterization via transauricular arterial access is technically not feasible , while transfemoral access is simple and suitable in rabbits .Blood collection via the jugular vein may be a more reliable and valuable method for pharmacokinetic studies in rabbits .

Objective To report and analyze the renal function improvement in a case with ad-vanced bilateral renal cell carcinoma after targeted therapy. Methods The patient was a 60-year-old man who complained of lower back pain for 1 month. Ultrasound and CT scan detected bilateral renal masses, left lesion was 11.0 cm×9.4 cm×8.5 cm, and the right one was 3.5 cm×4.3 cm×4.1 cm. X-ray examination showed metastatic lesions in liver and lower right lung. GFR was 20.39 ml/min of left kidney, 25.40 ml/min of right kidney. The renal biopsy confirmed renal clear cell carcinoma. Sorafenib was administrated 400 mg twice or once daily for 12 weeks. Results After the targeted therapy, the decreased bilateral kidney tumor sizes were identified by CT scan. There was liquid nec-rosis in the tumor, and no new metastatic lesion detected. The kidney function was improved as well. The total GFR increased to 71.38 ml/min. Left kidney GFR increased to 31.57 ml/min, right kidney GFR increased to 39.81 ml/min, respectively. Conclusion Targeted therapy could improve renal function in advanced renal cell carcinoma cases by controlling tumor development.
