Objective To evaluate the effect of mental intervention combined with simple brachial plexus anesthesia in children' upper extremity operation. Method 80 cases of8 ～ 12 years old children were selected after strict evaluation and screening,of who needed upper extremity operation(fractures internal fixation not included) ,and the surgery time less than 120 minutes. All the operations were completed under the simple brachial plexus anesthesia, and combined with mental intervention preoperatively and intraoperatively. The changes of HR and BP intraoperatively the psyche condition after the operation completed were observed and followed up the mental change postoperatively. Result All the operation were completed. The HR and BP were stable intraoperation (P ＞ 0. 05), the psyche was quiet after the operation completed,and no mental disorder was happened postoperative. Conclusion The mental intervention combined with simple brachial plexus anesthesia was safe in 8 ～ 12 years old children' upper extremity operation, and it deserved to spread and apply.

Objective To explore the etiopathogenisis of Reinke's edema. Methods To detect 15 samples of Reinke's edema of vocal cord mucosal and 5 samples of common vocal cord mucosal with S-P immunohistochemical method. Then to observe the effect of immunity class under the light microscope. To detect the expression of the VEGF and the production of the blood capillary in the sample of Reinke's edema of vocal cord mucosal with immunohisto-chemical method. Results There are 12 effects of sex in the 15 samples of Reinke's edema of vocal cord mucosal. There are effects of feminine in the 5 samples of common. Conclusion The main etiopathogenisis of Reinke's edema is that blood vessel grew ad libitum, the permeability of blood vessel increase and oxygen lack partly.

Objective To determine the effects of different anesthetic techniques on T-lymphocyte subsets in patients with esophageal carcinoma. Methods Forty patients were randomly assigned into general anesthesia group (group Ⅰ),or combined generae anesthesia with epidural anesthesia group(group Ⅱ). Peripheral blood CD3, CD4,CD8 were measured before induction ( T1 ), after anesthesia ( T2 ), end of operation ( T3 ), 1d ( T4 ), 3d ( T5 ) after surgery. Resolts CD3,CD4,CD8,CD4/CD8 decreased at T2 in the two groups. In group Ⅱ ,CD3,CD4,CD8,CD4/CD8 ratio almost returned to the baseline values at T4 ,while group Ⅰ did not. Conclusion Epidural anesthesia combined with general anesthesia can reduce depression of T-lymphocyte subsets induced by surgical trauma and anesthesia, and is the anesthetic tecnique of choice for cancer patients undergoing major operation.
