Objects To evaluate the immune protective effect of dexmedetomidine on breast cancer dur-ing perioperative radical mastectomy via sevoflurane inhalation general anesthesia. To explore reasonable anesthet-ic strategyfor breast cancer radical mastectomy. Methods Patients were divided into two groups. Patients in ex-perimental group receivedgeneral anesthesia with dexmedetomidine and sevoflurane. Control group means general anesthesia with sevoflurane only. In both groups, the level of cortisol, IL-6, IL-8 and of TNF-αin serum were measured at 5 time points , 30 minutes before anesthesia , after cutting skin , after surgery , 24 h after surgery and 72 h after surgery. Results The amount of anesthetic used to induce general anesthesia in the experimen-talgroup were lower than that of the control group.There is no obvious difference of cortisol , IL-6, IL-8 and of TNF-αin serumat the time of 30 min before anesthesia between two groups.Concentrations ofseveral markersin-creasedafter anesthesia, of which experimentalgroup were lower than that of the control group. Conclusions Dexmedetomidine could be immunoprotective for patient with breast cancer during perioperative radical mastecto-my via sevoflurane inhalationgeneralanesthesia. This study recommends usingmultiple anestheticdrugs to anes-thetize patients of breast cancer when performing radical mastectomy.

One patient with recurrent attacks of pancreatitis and pancreatic head mass had a long history of recurrent abdominal pain, abdominal distension, nausea and vomiting, and no significant alleviations were observed under non-surgical treatment in many hospitals. After the diagnosis and treatment by the multidisciplinary team of gastroenterology, hepatobiliary and pancreatic surgery, oncology, pathology, radiology and other departments of Third Xiangya Hospital of Central South University, the patient underwent pancreaticoduodenectomy to completely remove the painful lesion, without leaving histological basis for canceration caused by chronic inflammation. The safety of the surgery was greatly improved and no obvious complications were observed.
