After consultation with the patient, Academician Teng Gaojun and his team stated that the patient is of advanced age and has a complex medical condition, including atrial fibrillation with second-degree atrioventricular block, hypertension, coronary heart disease, and severe stenosis in the P2 segment of the right posterior cerebral artery. The tumor is located close to the hepatic vein and portal vein, making conventional tumor resection or microwave ablation surgery risky or difficult to completely ablate. NanoKnife tumor ablation therapy is a new and advanced technology in tumor ablation, which differs from traditional thermal ablation techniques in its mechanism of inactivation. It can selectively ablate tissues without being affected by thermal sink effects, effectively preserving important tissue structures such as blood vessels, nerves, bile ducts, and ureters, resulting in more thorough and precise tumor inactivation.

(Reported by Fuzhou Evening News) For the past two years, Ms. Zeng from Fuzhou has been battling with advanced liver cancer. After trying various conventional therapies, the cancer cells still had the upper hand. Recently, the newly introduced tumor ablation technology in our province, "nanoknife", came to her aid and brought a welcome reversal to Ms. Zeng's anti-cancer situation.

Recently, the Department of Radiation Oncology of the First People's Hospital of Zhumadian admitted a special patient. The patient is a 58-year-old female who was diagnosed with advanced liver cancer during a physical examination one and a half years ago. After receiving immunotherapy, chemotherapy, and cryoablation, the cancerous lesion still showed local progression.

Two years ago, Ms. Zeng was diagnosed with primary liver cancer during a physical examination. She received multiple treatments including "local ablation of liver cancer" and targeted therapy at the local hospital, and the tumor was effectively controlled.

In June 2022, the Pulsed Field Ablation (PFA) treatment device independently developed by Shanghai Yuanshan Medical successfully completed the first PFA surgery for atrial fibrillation patients at Huaihe Hospital of Henan University. Recently, the patient underwent a follow-up examination at the hospital and all indicators have recovered well.

On January 9, 2023, the first domestic nano-knife treatment for liver malignant tumors was successfully performed at Xiangya Third Hospital of Central South University. The surgery was carried out by Professor Liang Qi's team from the Interventional Department and Professor Fu Dianxun from Tianjin Medical University General Hospital. During the surgery, the High Voltage Steep Pulse Minimally Invasive Therapeutic system independently developed and produced by Yuanshan Medical Technology Co., Ltd(Alpmed). was used, and CT guidance was used to perform Nanoknife ablation for patients with dangerous organ liver portal tumors.
