In more than 30 years' work, we have completed many difficult operations, such as: super-selective hepatic artery embolization of bletilla striata, vertebroplasty of the second thoracic vertebra, percutaneous lumbar discectomy via anterior abdominal approach, percutaneous radiofrequency ablation via hepatic portal for metastatic tumor, interventional therapy via anterior cervical discectomy, interventional therapy for giant retroperitoneal tumor, carotid bifurcation stent implantation, jugular vein and portal vein-vena cava shunt, etc. It is the first in China to carry out minimally invasive interventional therapy for disc herniation, infertility, tumor with traditional Chinese medicine as embolic agent and dual interventional therapy for femoral head necrosis. It involves a wide range of diseases and technologies, and is proficient in various minimally invasive technologies.

In 2003, Dr. Ren Sheng began to pay attention to the research of cell application technology. At that time, the treatment of stem cells was limited to the simple treatment techniques of autologous cell culture and intravenous drip, and there were fewer diseases. At that time, there was a vague concept that as long as cells entered the body, they swam to the diseased site. Under the influence of this concept, the application of stem cells is extremely simple and the therapeutic effect is not ideal. Dr. Ren keenly felt that the input mode of stem cells is an important factor affecting its therapeutic effect.

In 2009, in cooperation with this team, we successfully applied stem cell hepatic artery interventional technology to treat 1 liver cirrhosis patients in Indonesia. Before treatment, the patient developed severe ascites, elevated transaminase and severe jaundice, and his liver function was grade 3. After 1 week treatment, ascites disappeared, albumin increased and transaminase decreased. The case was completed on June 27, 2009, and it is the first case of successful treatment of liver cirrhosis with allogeneic stem cells in China.

During October, 200913, Dr. Ren successfully treated nearly 1,000 patients with various diseases by using his exquisite minimally invasive technology and stem cell technology. Include severe liver disease, uremia, diabetic complications, Parkinson's disease, sequelae of cerebrovascular diseases, avascular necrosis of femoral head, lupus erythematosus, chronic obstructive emphysema, chronic pancreatitis and other diseases.

At the same time, the plastic surgery technology has been expanded, and the biological scaffold breast enhancement technology, biological scaffold facial skin filling and micro-needle implantation hair growth technology have been successfully completed.
