The incidence of liver cancer has been increasing year by year.In China,the incidence of liver cancer is 25.7/10 million.However,when the important organs have been involved or when the malignant liver tumors are located adjacent to the hepatic portal vital organs,the lesions are usually difficult to be surgically removed,and the curative results of chemotherapy and radiotherapy for such lesions are often poor.In recent years,along with the gradual rise of ablation techniques,the irreversible electroporation (IRE),regarded as a new ablation method that uses non-thermal energy,has been widely employed in clinical practice.Through generating instantaneous high voltage electrical pulses,IRE produces irreversible nanoscale damage to the cell membrane.Both domestic and foreign researches have indicated that for the treatment of inoperable primary or metastatic liver tumors IRE can effectively inactivate the tumor tissue while the lumen architecture of the vessels can be preserved and large vessel or bile duct will not be damaged.This paper aims to make a comprehensive review about IRE device structure,mechanism of therapeutic action,preclinical studies,clinical application methods and clinical efficacy in order to provide reference for the application of this technology in clinical practice.(J Intervent Radiol,2017,26:285-289)

Objective To observe the influence of human umbilical cord wharton′s jelly‐mesenchymal stem cells(WJ‐MHCs) on the tumor necrosis factorα (TNF‐α) and N‐terminal pro‐brain natriuretic peptide(NT‐proBNP) in rats with heart failure of a‐cute myocardial infarction .Methods Totally 80 male rat models of heart failure of acute myocardial infarction were made by isopre‐naline(ISO) 200 mg/kg injected subcutaneously twice at an interval of 24 hours .After one week ,24 survival rats were randomly di‐vided into WJ‐M HCs transplantation group and normal control group .Sham group was made of 12 health rats ,and then each of the three groups was subdivided into pre‐transplantation group and post‐transplantation group 4 weeks later .WJ‐MHCs transplantation group was transplanted with WJ‐MHCs with DAPI labeled after ISO injected one week .Sham group and normal group were un‐treated and normally bred .The left ventricular ejection fraction(LVEF) measured by before transplantation and post‐transplantation 4 weeks later .The injected cells and the expression of TNF‐αwas measured .Results Compared to pre‐transplantation group ,WJ‐M HCs transplantation group increased the LVEF(P<0 .05);compared to pre‐transplantation and normal control ,WJ‐M HCs trans‐plantation group reduced the TNF‐αand NT‐proBNP in the serum(P<0 .05)and the expression of TNF‐α from the heart tissue (P<0 .05);compared to normal transplantation ,WJ‐M HCs transplantation group reduced the mortality from 33 .3% to 16 .7% ;immunofluorescence demonstrated that transplanted cells were still found alive in the heart after transplantation 4 weeks later .Con‐clusion Transplantation of WJ‐MHCS down‐regulates TNF‐α and NT‐proBNP in the serum in the serum and the expression of TNF‐αfrom the heart tissue and up‐regulates the LVEF in rats with heart failure of acute myocardial infarction .

Objective To assess the effectiveness of a novel mobile health patient management system involving doctors, nurses, and patients ( TRIO mode) on glycemic control and self-monitoring of blood glucose (SMBG) compliance among the type 2 diabetes mellitus ( T2DM) patients using basal insulin standardization treatment in China. Methods From April 2014 to April 2015, 416 hospitals in 110 cities of 30 provinces, municipalities, and autonomous regions across China were selected to participate in the program. A Online-to-Offline ( O2O) integrated mobile health patients management system with mobile terminals for the doctors, nurses, and patients was applied in the program for patient education, follow-up, and data collection. For all the newly recruited patients, the baseline information was collected and a first-day patient education program were provided by a designated nurse. In the 12-week follow-up period, data of basal insulin doses and fasting plasma glucose ( FPG) values were collected from the patients by text messages or tracking phone call by the nurse. The patients also received timely standardized patients health education and glycemic control guidance by participating in thepatient education forum anddoctors' hotline in order to help them achieve the glycemic control goals. Results A total of 102 524 patients using basal insulin treatment were eligible and enrolled in the program. 64 420 patients completed the 12 weeks follow-up and provided at least one FPG value at all five follow-ups. In total, 62. 6% (40 334 / 64 420) of the patients reached the FPG control target(FPG≤7. 0 mmol/ L) at the end of follow-up period. The weekly average FPG for patients with complete SMBG data decreased from 10. 58 mmol/ L to 6. 91 mmol/ L while the FPG control rates increased from 13. 4% to 69. 2% . The weekly average FPG for the patients provided incomplete SMBG data decreased from 10. 54 mmol/ L to 7. 13 mmol/ L while the FPG control rates increased from 13. 6% to 62. 2% . The FPG control rates for the patients provided complete SMBG were 1. 74 times higher than those patients provided incomplete SMBG. Based on a GEE model, the average decline of the FPG and the increase of the FPG control rates were significantly better for patients who provided complete SMBG as compared to the patients with incomplete SMBG data. The results of the multivariate logistic regression analysis showed that factors such as receiving the first-day education, participating in the follow-up patient education forum, and the doctors' hotline were significantly associated with the improvement of the SMBG compliance, the treatment adherence, and the FPG control rates. The SMBG compliance and the treatment adherence for patients who completed first-day education were 1. 68 times and 1. 22 times higher, respectively. For the patients who participated in follow-up education activities, their SMBG compliance and treatment adherence were 3. 17 times and 3. 36 times higher, respectively. Conclusion The innovativeTRIOmobile health patient management mode was feasible and effective for better managing the type 2 diabetes patients initiated on basal insulin treatment in China. Active participation in the first-day education program and the follow-up patient education activities can effectively improve the SMBG compliance and the treatment adherence, and therefore play an important role in helping patient achieving FPG control in a faster manner.

nm23-H1 is a proven tumor metastasis suppressive gene, tumor metastasis phenotype could be reversed by transfected nm23-H1 cDNA. This study was conducted to transfect nm23-H1 cDNA into L9981 cells and to explore the function of nm23-H1 in reversing the malignant phenotype of L9981 cells. The plasmid of pLXSN-nm23-H1-EGFP was constructed by gene clone technique, and the transfected nm23-H1 cDNA cell lines of L9981-nm23-H1 was established. The protein expression of nm23-H1 was detected by Western blot. The biologic features of L9981-nm23-H1 cells were studied in vitro and in vivo. The results showed that the fusion protein of nm23-H1-EGFP was stable, continuous and expressed with high efficiency in L9981-nm23-H1 cells. The cell proliferation, colon formation and invasive ability are significantly lowered in L9981 cells transfected nm23-H1 cDNA (P < 0.01); the tumorgenesis and the lung metastasis incidence was lower in tranfected nm23-H1 cells than in L9981 and L9981-Plxsn in nude mice (P < 0.01); the rate for inhibiting tumorgenesis of nm23 -H1 was 82.56%. These data suggest that the malignant phenotype could be reversed by wild nm23-H1 gene in L9981 cells.

Objective To summarize and analyze the perioperative complications of irreversible electroporation (IRE) ablation in treating tumors at different locations and to discuss their managements. Methods A total of 200 patients with tumors, including pancreatic tumor (n=71), liver tumor (n=64) and other tumors (n =65), were enrolled in this study. All patients received IRE ablation treatment. The perioperative complications were recorded and the data were statistically analyzed. The causes of severe complications and the treatment of complications were discussed. Results None of the patients died during the course of IRE ablation procedure. Severe postoperative complications occurred in the patients with pancreatic tumor or liver tumor, including duodenal artery bleeding in 3 patients with pancreatic tumor, which occurred at 10 days, 11 days and 15 days after IRE ablation respectively, and gastrointestinal bleeding (n =1) and biliary septic shock (n=1) in 2 patients with liver tumor, which occurred at 9 days after IRE ablation, the clinical symptoms were controlled after interventional embolization and/or vascular ligation together with anti-infective therapy. All minor complications were relieved after symptomatic treatment within 14 days. Conclusion IRE ablation has less systemic inflammatory response, and both the intraoperative and postoperative adverse reactions can be easily controlled, besides, IRE ablation has higher clinical safety. Although IRE ablation procedure may damage the internal or peripheral vessels of the pancreatic tumor, this severe complications can be effectively avoided if proper measures are adopted based on the causes of complications.
