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 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 investigate the values of echocardiographic parameters for predicting the spontaneous closure of the ductus arteriosus in preterm infants .Methods A retrospective study of 110 preterm infants from October 2013 to October 2014 in our hospital was done .Examination was done at 1 ,3 ,7 d with echocardiography for those infants .Diameter of left atrium(LA) ,aotic root(AO) and arterial canal‐related parameters (the smallest width of ductal color Doppler flow jet and the maximum velocity at the ductus) at first .Preterm infants in this study were divided into two groups .The early patent ductus arterisus group included ones whoes ductus didn′t closed spontaneous in 7 d ,and the control group included ones whoes ductus closed spontaneous in 7 d ,and then the echocardiographic parameters between the two groups were compared .Results (1)The rates of ductus arteriosus sponta‐neous closure in preterm infants at 3 ,7 d were 70 .9% (78/110) ,78 .2% (86/110) ,respectivly .(2)When compared with the control group ,The rate of LA/AO in patent ductus arterisus group were higher than that of the control group(P<0 .01);The smallest width of ductal color Doppler flow jet in patent ductus arterisus group were bigger than that of the control group(P<0 .01);The maximum velocity at the ductus in patent ductus arterisus group were lower than that of the control group(P<0 .05) .(3)The best critical points of the LA/AO ,the smallest width of ductal color Doppler flow jet and the maximum velocity at the ductus of the spontaneous ductus arteriosus closure in preterm infants were 1 .32 mm ,2 .56 mm and 185 .5 cm/s ,respectivly .Conclusion Echo‐cardiography plays a significant role in prediction of the spontaneous closure of the ductus arteriosus in preterm infants .
