ABSTRACT
Objective:To study the safety and efficacy of liquid isolation assisted technology in ultrasound-guided percutaneous radiofrequency ablation for hepatocellular carcinoma adjacent to liver surfaces.Methods:A retrospective study was conducted on 246 patients with hepatocellular carcinoma near liver surfaces treated by radiofrequency ablation from November 2016 to November 2019 at the Department of Hepatobiliary and Pancreatic Surgery, Affiliated Tumor Hospital of Zhengzhou University. There were 182 males and 64 females, aged (56.7±9.2) years. The patients were divided into the liquid isolation group with liquid isolation assisted technology for radiofrequency ablation ( n=131) and the conventional treatment group with conventional radiofrequency ablation ( n=115). The complication, one-time complete ablation and progression-free survival rates were compared between the two groups. Results:The incidence of intraoperative complications in the liquid isolation group was 21.4% (28/131), versus 20.9% (24/115) in the conventional treatment group. There was no significant difference between the two groups ( P>0.05). The incidence of postoperative complications in the liquid isolation group was 20.6% (27/131), which was significantly lower than that in the conventional treatment group 33.9% (39/115) ( P<0.05). The incidence of postoperative pain in the liquid isolation group was 6.1% (8/131), which was significantly lower than that in the conventional treatment group 15.7% (18/115) ( P<0.05). For the 131 patients in the liquid isolation group, there were 183 tumors near to liver surfaces. For the 115 patients in the conventional treatment group, there were 142 lesions near to liver surfaces. The one-time complete ablation rate in the liquid isolation group was 94.0% (172/183), which was significantly higher than the 75.4% (107/142) in the conventional treatment group ( P<0.05). The progression-free survival rate in the liquid isolation group was significantly better than that in the conventional treatment group ( P<0.05). Conclusion:The liquid isolation technique increased the one-time complete ablation rate of liver cancer adjacent to liver surfaces, reduced the incidence of postoperative complications and improved prognosis.
ABSTRACT
Objective To study the characteristics of skinfold thickness of Han adults in Jiangsu province . Methods The skinfold thicknesses of facial , subscapular , suprailiac , biceps , triceps and calf on 311 urban adults ( 157 males and 154 females) and 421 rural adults ( 213 males and 208 females ) of Han were investigated in Huaian city of Jiangsu province .Results The thickness of skinfold of urban females were thicker than that of urban males .Rural adults were the same .Han adults of Jiangsu showed the most significant differences between urban areas and rural areas .The values of six skinfold thicknesses of Jiangsu urban adults have positive correlation with age .Conclusion Han adults of Jiangsu show the most significant differences between genders .
