Objective To investigate anesthesia effect comparision of the Rayleigh fentanyl-propofol intravenous anes-thesia and epidural anesthesia and analyze the safety and feasibility of them. Methods A total of 70 cases of the pa-tients undergoing laparoscopic surgery were randomly divided into A,B groups, 35 cases in each group, group A used Rayleigh fentanyl-propofol intravenous anesthesia and group B used lumbar epidural anesthesia. Results Narcotic ef-fect, pain, muscle relaxant and internal force of group A were better than that of group B (P<0.05, P<0.01); There were no significant difference of SBP, DBP, MAP, HR, SpO2 between group A and group B; Intraoperative inflow,inci-dence of postoperative nausea and vomiting and the use of ephedrine in group A were less than group B(P<0.01). Con-clusion In gynecological laparoscopic surgery anesthesia, the effect of Rayleigh fentanyl-propofol intravenous anesthe-sia,which is easy and security, is better than that of lumbar epidural anesthesia.

Objective:To evaluate the effect of stored autologous blood transfusion on the function of bone marrow hematopoietic stem cells and the recovery of reticulocytes in peripheral blood of rabbits.Methods:Thirty healthy male New Zealand rabbits, aged 3-6 months, weighing 2.5-3.0 kg, were divided into 5 groups ( n=6 each) using a random number table method: control group (C group), operation group (O group), blood collection group (O+ B group), stored autologous whole blood group (O+ WB group) and stored autologous component blood group (O+ CB group). In O+ B group, O+ WB group and O+ CB group, blood was collected via the right femoral artery at a rate of 3-5 ml/min at 7 days before surgery, the blood volume was 10% of the total blood volume, and blood was stored at 4-6 ℃.In O+ CB group, blood was centrifuged to remove plasma and white blood cells, and red blood cell suspension was prepared and placed in a blood storage bag.In O, O+ B, O+ WB and O+ CB groups, hepatectomy was performed, and bleeding was performed through the right femoral artery at a rate of 3-5 ml/min, and the blood volume was 10% of the total blood volume.Lactated Ringer′s solution 1 ml/min was intravenously infused during surgery in O and O+ B groups, stored autologous whole blood was intravenously infused during surgery in group O+ WB, and stored autologous red blood cell suspension 1 ml/min was intravenously infused during surgery in group O+ CB.Bone marrow blood samples were collected immediately before the start of surgery (T 2) and at 6 and 24 h after surgery (T 3, 4) to determine the percentage of CD34 + cells, cell cycle and relative expression of telomere DNA.Peripheral venous blood samples were collected before storage (T 1) and at T 4 for determination of the percentage of reticulocytes. Results:Compared with group C, the percentage of CD34 + cells was significantly increased at T 3 and T 4, the percentage of CD34 + cells in G1 phase was decreased, and the expression of telomere DNA in CD34 + cells was up-regulated in group O, and the percentage of reticulocyte in peripheral blood was increased at T 4 in the remaining 4 groups ( P<0.05). Compared with group O, the percentage of CD34 + cells was significantly increased at T 2-4, the percentage of CD34 + cells in G1 phase was decreased, and the expression of telomere DNA in CD34 + cells was up-regulated in O+ B, O+ WB and O+ CB groups, and the percentage of reticulocyte in peripheral blood was increased at T 4 in O+ WB and O+ CB groups ( P<0.05). Compared with group O+ B, the percentage of CD34 + cells was significantly increased at T 3 and T 4, the percentage of CD34 + cells in G1 phase was decreased, and the expression of telomere DNA in CD34 + cells was up-regulated in O+ WB and O+ CB groups, and the percentage of reticulocyte in peripheral blood was decreased at T 4 in O+ WB and O+ CB groups ( P<0.05). Compared with O+ WB group, the percentage of CD34 + cells was significantly decreased at T 3 and T 4, the percentage of CD34 + cells in G 1 phase was increased, the expression of telomere DNA in CD34 + cells was down-regulated, and the percentage of reticulocytes in peripheral blood was increased at T 4 in group O+ CB ( P<0.05). Conclusion:Stored autologous blood transfusion can inhibit the function of bone marrow hematopoietic stem cells and is not helpful for recovery of reticulocytes in peripheral blood of rabbits; stored autologous component blood transfusion has less effect on the hematopoietic function of bone marrow than stored autologous whole blood transfusion.

OBJECTIVETo compare the efficacy difference between acupotomy and acupuncture in the treatment of avascular necrosis of femoral head at the early and middle stages.

METHODSThe randomized controlled prospective study method was adopted. Sixty cases of avascular necrosis of femoral head at Ficat-ArletⅠto Ⅱ stages were randomized into an acupotomy group (32 cases) and an acupuncture group (28 cases) by the third part. In the acupotomy group, the acupotomy was adopted for the loose solution at the treatment sites of hip joint, once every two weeks, totally for 3 times. In the acupuncture group,points around the hip joint were selected and stimulated with warm acupuncture therapy, once every day, for 6 weeks. Harris hip score was observed before and after treatment. The efficacy was evaluated in the two groups.

RESULTSHarris hip score was improved significantly after treatment in the two groups (both<0.05). The result in acupotomy group was better than that in the acupuncture group (<0.05). The effective rate was 90.6% (29/32) in the acupotomy group, better than 75.0% (21/28) in the acupuncture group after treatment (<0.05).

CONCLUSIONSHarris hip score and the effective rate in the acupotomy group are better than those in the treatment with routine acupuncture for avascular necrosis of femoral head at the early and middle stages.
