Objective To discuss the effect of body posture change on the catheter tip position of totally implantable venous access port (TIVAP).Methods Under ultrasound guidance,implantation of TIVAP was carried out through bedside puncturing of internal jugular vein or subclavian vein.After the implantation of TIVAP,X-ray chest films of both erect position and supine position were taken to check the catheter tip position.The distance from the upper edge of the first thoracic vertebra to the catheter tip was separately measured on the erect position and supine position chest films.The shift of the catheter tip position was judged by the difference in the distance measured on chest films as well as by the comparison with the bony anatomic marks.Results Successful implantation of TIVAP was accomplished in 86 patients.When the patients changed from erect position to supine position,the catheter tip of TIVAP moved caudally in 71 patients,with the mean displace distance being (12.29±7.48) mm;the catheter tip of TIVAP moved cephalad in 31 patients,with the mean displace distance being (5.00±3.79) mm;and the catheter tip of TIVAP remained in the same position in 2 patients.When the patients changed from erect position to supine position,the catheter tip of TIVAP had a tendency to move toward the foot side,the average displace distance was (-9.32±9.36) mm,the difference in catheter tip location between two photographic positions was statistically significant (P＜0.000 1).No statistically significant correlation existed between the changes of catheter tip position and the sex,age,height,weight as well as body mass index (P＞0.05).Conclusion After the implantation of TIVAP,the position of catheter tip will change with patient's body posture.When patient's posture changes from erect position to supine position the tip of the catheter tends to shift towards the atrium.

Objective To compare the curative effect of transarterial chemoembolization (TACE)plus microwave ablation (MWA) with that of pure TACE in treating hepatocellular carcinoma (HCC) larger than 5 cm in diameter.Methods The clinical data of 208 patients with HCC,who were admitted to authors' hospital to receive treatment during the period from June 2014 to December 2015,were retrospectively analyzed.The patients were divided into combination group (n=40,treated with TACE+MWA) and TACE group (n=168,treated with TACE only).By using 1 ∶ 1 pairing,the curative results of the two groups were analyzed.The survival of patient was taken as the primary observation index,and both the one-month solidtumor response value determined with modified Response Evaluation Criteria in Solid Tumors (mRECIST)and the reduction in AFP level were the secondary observation indexes.Results A total of 31 pairings were accomplished.The baseline data of the paired groups were comparable.The results indicated that half-,one-,1.5-,2-and 2.5-year survival rates in the combination group were 96.8％,90.3％,86.8％,82.5％ and 70.7％ respectively,which were significantly better than those of 77.4％,61.3％,53.6％,48.2％ and 24.1％ respectively in the TACE group (P=0.011).The one-month tumor-control rate and the reduction degree in AFP level of the combination group were better than those of the TACE group.No severe complications occurred in both groups.Conclusion For the treatment of HCC that is larger than 5 cm in diameter,TACE combined with MWA is superior to pure TACE in increasing survival rate as well as in improving tumor-control rate.

To explore the application of humanistic care in children’s fever clinics， the children’s fever clinics of Guangzhou Women and Children’s Medical Center conducted relevant research using narrative medicine as a guiding concept. This paper elaborated on the medical humanistic dilemmas and narrative care needs in children’s fever clinics， and focused on exploring the practice paths of narrative medicine in pediatric with Chinese characteristics from five dimensions， including the cultivation of nursing staff’s abilities of professional narrative and humanistic care， the establishment of health lectures featuring narrative patient education， the alleviation of medical anxiety for children and their families， related support of narrative nursing， and caring services. The aim was to improve the narrative care ability of nurses in children’s fever clinics， develop methods for pediatric patients that can eliminate the fear of seeking medical treatment， and protect children’s physical and mental health. A carrier of care， support， and emotional expression can be provided for parents. The foundation for nursing staff to achieve professional growth through narrative reflection can be laid. Thus， it can assist in establishing a life narrative community relationship between doctors and patients， and jointly explore the meaning of life.
