ObjectiveTo summary the clinical application of a new and minimally invasive ablation technology for tumors—irreversible electroporation. MethodsRelated domestic and foreign literatures were reviewed. ResultsCompared with traditional ablation technology, irreversible electroporation had advantages of complete ablation with well-demarcated margin, preservation of vital structures, avoidance of heat/cold-sink effect, and short ablation time. Irreversible electroporation may play an import role in patients who couldn't tolerate surgery in reason of combining with other disease, who were not suitable for surgery due to late tumors, and who had solid tumors of less than 3 cm in diameter. ConclusionAs a new and minimally invasive ablation technology for tumors, irreversible electroporation has high safety and efficacy.
Objective To study clinical efficacy of irreversible electroporation in the treatment of advanced hepatic carcinoma. Methods Between July 2015 and September 2015, 8 patients with advanced hepatic carcinoma (10 tumors) were treated by ultrasound-guided irreversible electroporation, using pertacuneous, laparoscope or open surgery in the Rockets Army General Hospital of PLA. Prospectively collected and summarized the clinical data. Finally, analyzed the therapeutic effect of irreversible electroporation. Results Compared with before treatment, the quality of life score significantly increased 〔(37.75±4.65) scores vs. (22.25±2.87) scores, P=0.000〕 in 3 months after treatment of irreversible electroporation, but value of serum total bilirubin (56.37 mmol/L vs. 150.40 mmol/L, P=0.046), direct bilirubin (58.69 mmol/L vs. 71.60 mmol/L, P=0.012), alanine aminotransferase 〔(52.63±12.14) U/mL vs. (87.28±27.94) U/mL, P=0.003〕, asperate aminotransferase 〔(48.45±13.75) U/mL vs. (74.40±21.09) U/mL, P=0.000〕, and alpha fetoprotein (82.10 ng/mL vs. 159.20 ng/mL, P=0.042) significantly decreased. One patient suffered from persistent upper abdominal pain after irreversible electroporation, but no serious complications, such as infection, biliary fistula, hemorrhage, and liver or kidney failure occurred in all 8 patients. Abdominal enhanced CT scanning or MRI in 3 months after irreversible electroporation showed complete ablation in 7 patients and incomplete ablation with some residual in 1 patient. Eight patients were followed up for 3-5 months 〔an average of (4.0±0.9) months〕. During follow-up period, all patients had been alive with 1 case of recurrence. Conclusion The effect of ultrasound-guided irreversible electroporation in the treatment of advanced hepatic carcinoma is remarkable, and it may deserve clinical application in consideration of its safety and efficacy.
Bones are stained into red color with feeding madder, but we do not know whether the fed madder can change the bone biomechanical properties and bone mineral contents in animals. In this research, we established a rat model with feeding madder. The bone biomechanical properties were detected by universal material mechanics, bone mineral contents were detected by inductively coupled plasma mass spectrometry and spectrometer, and red color material in bone was analyzed by high performance liquid chromatography. The results showed that bone biomechanical parameters in femur diaphysis in the 10% and 15% group rats were significantly higher than those in the control group after feeding madder for 6 months. The level of calcium, magnesium and zinc in femur diaphysis in 10% and 15% group rats were higher than those in the control group after feeding madder for 6 months. However, it was shown that the kidney congestion andhyperemia and the level of blood urea nitrogen and creatinine in the 15% group rats were significantly different compared to those in the control group rats after feeding madder for 6 months. The red colored material in bone is related to alizarin analyzed with high-performance liquid chromatography. The conclusion could be drawn that feeding 10% madder in diet was not toxic to the rats fed for 6 months, and it could improve bone biomechanical properties and increase bone mineral elements.
