RESUMO

@#Objective     To establish a model of transplanting neonatal cardiomycytes into the wall of rat inferior vena cava. Methods     Neonatal cardiomyocytes (n=6, 5×106cells each, A group) or medium (n=6, B group) only were transplanted into the wall of inferior vena cava in female Fisher rats. At 21 days after transplantation, the contraction of transplanted cardiomyocytes was assessed and the inferior vena cava was processed for histology. Results     Distinct rhythmic beating of the vena cava at the site of cell transplantation before and after the aorties were clamped (at a rate 141± 47 rpm and 88± 44 rpm which was dramaticly lower than aortic beating, with a statistical difference at P value of 0.03). Cardiomyocyte was seen in 6 rats who had neonatal cardiomyocyte transplantation, but not in 6 rats receiving media. Hematoxylin and eosin staining showed viable cardiomyocytes in the wall of the vena cava in 6 rats treated with neonatal cardiomyocytes, but not in 6 rats receiving media. Conclusion     This study shows that neonatal cardiomyocytes can survive, mature and spontaneously and rhythmically contract after they are transplanted in the wall of inferior vena cava.

RESUMO

Objective To explore the clinical application and safety of treatment of percutaneous radioactive 125I seed implantation treatment in lung metastases under CT guidance.Methods Twenty-seven lung metastatic malignancy cases (67 nodules) were studied.Eighteen cases (46 nodules) were hepatic cancer,4 cases (9 nodules) were prostate cancer,and 5 cases (12 nodules) were breast carcinoma.Diameters of lung nodules ranged from 0.5 cm to 4.0 cm with an average diameter of 2.1 cm.125I seeds were embedded under CT guidance,using 2 to 33 particles/nodule with an activity of 18.5 to 29.6 MBq/grain for each particle.Tumor matched peripheral dose was 90-120 Gy.Postoperative validation and quality evaluation followed.Results Four months later,24 nodules showed CR,30 showed PR,5 showed NC and 8 showed PD.The total effective rate was 80.6% (54/67).In the course of treatment,11 patients had pneumothorax,3 had heavy lung compression and 4 had hemoptysis.All conditions were improved by pleural puncture or under close follow-up observation.Conclusion 125I seed implantation is an effective and safe technique in treatment of metastatic lung tumors under CT guidance.

RESUMO

Thirty patients with malignant obstructive jaundice were treated with biliary stent implantation+brachytherapy+conformal radiotherapy (study group; n=15) or biliary stent implantation alone (control group; n=15). Total bilirubin (TBIL) levels significantly declined within 1 month in both groups. However, at 6 months, TBIL values began to increase in the control group and continuously declined in the study group. Maximum tumor diameter increased in the control group, while decreased in the study group (remission rate, 13/15 ). As for the study group, the survival rate at 0. 5, 1, and 2 years was 15/15,14/15, and 10/15, respectively, higher than the control group (15/15,5/15,and 1/15) . Combining biliary stent implantation with brachytherapy and conformal radiotherapy might be a safe and effective treatment of choice for patients with malignant obstructive jaundice.

RESUMO

0.05). In both A and B groups the number of CD_3~+, CD_4~+, CD_8~+ T cells and NK was signficantly higher after treatment than before treatment(P0.05). The amount of CD_3~+,CD_4~+ T cells and NK was obivously lower after treatment than before treatment in C group, and CD_8~+ T cells amount significantly increased after treatment compared with before treatment(P
