Percutaneous transhepatic biliary preset implantation of after-loading radiotherapy catheter for the treatment of bile duct carcinoma of ampulla: preliminary results of 10 cases / 介入放射学杂志

Objective To discuss the safety and feasibility of percutaneous transhepatic biliary preset implantation of after-loading radiotherapy catheter in treating bile duct carcinoma of ampulla.Methods A total of 10 patients with carcinoma of ampulla were collected.After percutaneous transhepatic biliary stent implantation was accomplished,the after-loading radiotherapy catheter was inserted via the guide wire.Based on the lesion's location,the positioning of both the catheter tip and the simulation radioactive source implanted through catheter was conducted.Each time before irradiation,the positions of the catheter and the radioactive source were reset under CT or fluoroscopic guidance in order to ensure that the lesion could get adequate internal irradiation dose.Results Percutaneous transhepatic biliary implantation of after-loading radiotherapy catheter and the positioning of simulation radioactive source were successfully accomplished in all 10 patients,and the total internal irradiation dose was completed within 5-7 days after catheter implantation.No severe complications occurred during the whole therapeutic process.Conclusion The technology of percutaneous transhepatic biliary preset implantation of after-loading radiotherapy catheter is safe and feasible,it carries high success rate with less complications.This therapy can improve the patency rate of biliary stent,and,as a palliative treatment,it is suitable for patients with carcinoma of ampulla.This treatment is worthy of application and promotion.

Measuring the length of the proportional units(PU) of lower limb and analyzing the relationship / 全日本鍼灸学会雑誌

Measuring the length of the proportional units of the lower limb and analyzing their interrelations showed that between genders there were significant differences in a length of one can of perpendicular proportional unit for various regions of the lower limb; within the same gender, there were different results in comparing the lengths of one of perpendicular proportional unit among various regions of the lower limb.

Safe Needling Depth for Potentially Dangerous Acupoints in the Head and Neck / 全日本鍼灸学会雑誌

Fifty-one fresh adult cadavers (male 21, female 30) were randomly selected. The required acupoints were localized and then the cadavers were frozen for anatomical dissection. Distance between the shallow point on the skin and the dangerous zones were measured after the cavaders were unfrozen. Data were analyzed statistically. The results showed that safe needling depths for Fengfu, Yamen, Fengchi and Jingming were 40.08mm, 38.10mm, 39.70mm and 34.25mm, respectively
