Background and purpose:Thermal ablation (radiofrequency ablation, RFA/microwave ablation, MWA) is the most commonly used minimally invasive technique for the treatment of liver cancer. Real-time shear wave elastography (SWE) is a new type of ultrasonic imaging technology, which was used in our study to monitor thermal ablation of liver cancer. This study aimed to investigate the stiffness change of liver cancer and that of surrounding liver parenchyma before and after thermal ablation, and to evaluate the application of SWE for monitoring thermal ablation for liver cancer.Methods:From Oct. 2014 to Apr. 2015, a total number of 36 patients, with 39 lesions, were treated with RFA or MWA and got complete response. SWE examination was performed before and after ablation. The SWE-mean, SWE-min, SWE-max, SWE-SD of lesions and the surrounding liver parenchyma were measured. Statistical analysis was made to compare the stiffness changes of liver cancer with those of the surrounding liver parenchyma before and after thermal ablation, and to determine whether there were differences between two different ablation modes.Results:Before and after ablation, the SWE-mean of lesions was (30.09±11.67) kPavs (52.11±17.56) kPa,SWE-min was (10.46±8.22) kPavs (20.57±11.42) kPa, SWE-max was (51.50±20.84) kPavs (88.54±27.75) kPa, SWE-SD was (10.63±4.30) kPavs (16.89±7.72) kPa; There were statistically signiifcant differences (P<0.05). Before and after ablation, the SWE-mean of surrounding liver parenchyma was (8.84±2.82) kPavs (8.91±2.78) kPa, SWE-min was (4.77±1.95) kPavs (4.69±1.90) kPa, SWE-max was (13.82±3.79) kPavs (14.34±3.97) kPa, SWE-SD was (3.24±1.32) kPavs (3.37±1.29) kPa; There were no statistically signiifcant differences (P>0.05). After ablation, the SWE-mean of RFA and MWA was (45.55±10.91) kPavs (60.59±20.99) kPa, SWE-min was (18.95±8.86) kPavs (25.93±10.93) kPa, SWE-max was (76.58±15.51) kPavs (104.01±32.59) kPa, SWE-SD was (13.82±3.52) kPavs (20.85±9.77) kPa; There were statistically signiifcant differences (P<0.05).Conclusion:SWE can quantitively analyze the stiffness of lesions. The ablation zone became stiffer after RFA or MWA, and the ablation zone of MWA was stiffer than that of RFA. Two kinds of ablation methods did not signiifcantly affect the stiffness of liver parenchyma around the lesion. SWE could potentially be used to monitor thermal ablation of liver cancer.

Objective To evaluate the therapeutic effect of acupoint catgut embedding on gastrointestinal dysfunction after surgery in patients with severe traumatic brain injury.Methods Sixty-eight consecutively hospitalized patients with gastrointestinal dysfunction after surgery in patients with severe traumatic brain injury admitted to the Department of Intensive Care Unit (ICU) in the First Affiliated Hospital of Zhejiang University of Chinese Medicine from January 2015 to December 2015 were enrolled.Six of those patients were withdrawn from the course of observation,and actually only 62 patients entered the study.They were divided into an observation group (32 cases) and a control group (30 cases) by random number table.All the patients of two groups were given conventional treatment of western medicine for consecutive 7 days.The observation group was additionally treated with acupoint catgut embedding.The control group took mosapride tablets via a nasogastric tube 5 mg,3 times a day.Intra-abdominal pressure (IAP),gastric residual volume (GRV),time for reaching standard enteral nutrition,serum diamine oxidase(DAO),D-Lactate activity,incidence of hospital-acquired pneumonia (HAP),hospitalization days in ICU,28-day mortality and adverse reactions of acupoint catgut embedding were observed in the two groups.Results After treatment,the levels of IAP,DAO,D-lactic acid were lower than those before treatment,GRV was less than that before treatment in the two groups,and after treatment for 7 days the changes were more significant in the observation group [IAP (cmH2O,1 cmH2O =0.098 kPa):12.42±3.11 vs.17.70 ± 2.98,GRV (mL):129.54 ± 57.54 vs.242.91 ± 99.29,DAO (U/L):9.06± 2.84 vs.13.60 ± 7.16,D-Lactate (mg/L):16.47 ± 5.39 vs.26.29 ± 9.62,all P ＜ 0.01].Days of mechanical ventilation (days:6.97 ± 4.13 vs.9.23 ± 4.61),time for reaching standard enteral nutrition (days:4.25 ± 3.15 vs.5.50 ± 3.12) and hospitalization days in ICU (days:9.50± 4.03 vs.12.20 ± 6.38) in observation group were significantly shorter than those in control group (all P ＜ 0.05).The incidence of HAP [15.6％ (5/32) vs.40.0％ (12/30)] and 28-day mortality [3.1％ (1/32) vs.6.7％ (2/30)] in observation group were obviously lower than those in control group.The patients in observation group had no significant adverse reactions of acupoint catgut embedding.Conclusions Acupoint catgut embedding therapy is not only easy to operate,but also can effectively improve gastrointestinal motility and intestinal barrier function in patients with gastrointestinal dysfunction after surgery of severe head injury,thus it is beneficial to reaching the enteral nutritional goal in less time,reducing the incidence of HAP,shortening the hospitalization time in ICU and promoting the recovery of the patients.
