Objective To study the influence of sivelestat sodium on platelets activity,injury and count during cardiopulmonary bypass (CPB)in dogs.Methods Twelve adult health dogs were randomly divided into control group (group C,n=6)and sivelestat sodium group (group S,n=6). Sivelestat sodium at 15 mg/kg was administrated intravenously before the establishment of CPB and then was maintained intravenously at 10 mg·kg-1·h-1 to the end of CPB in the group S,and the same volume of saline was used in the group S.The levels of neutrophil elastase (NE),malondialdehyde (MDA),granular membrane protein-140 (GMP-140),thromboxaneB2 (TXB2 ),the count of plate-lets and the hematocrit (Hct)were measured before CPB,15 and 45 min after cross-clamping and 30, and 60 min after aortic unclamping in both groups.Results The levels of NE,GMP-140,TXB2 at T2-T5 and MDA at T3-T5 were significantly higher than those at T1 in both groups;moreover the lev-els were significantly lower in group S than group C (P<0.05).The levels of Plt at T2-T5 were sig-nificantly lower than those at T1 in both groups;moreover the levels were significantly higher in group S than group C (P <0.05).Conclusion Sivelestat sodium reduced the levels of plasma NE, MDA,GMP-140,TXB2 inhibited the activation of Plt,and decreased the injury and consumption of Plt,which presents the protective effects for Plt during CPB.

Objective To explore the relationships between erythropoietin( EPO), endothelin - 1 (ET - 1) and perinatal anoxia. Method ELISA was used to test cord blood EPO and ET-1 in 54 high risk neonates as subjects and 14 healthy neonates as controls.Results The cord blood EPO levels in amniotic fluids turbid Ⅲ degree group and group eclampsia/pre - eclampsia were higher than those in control group (t= 4.0842,3 680 allP

Confronted with similar problems and difficulties in mainland,Taiwan reformed its medical education. The reform included setting up flexible program,formulating objective and detailed rotary guide,making the best of the resources,implementing medical humanities education based on the reality and forming unique cultivation system and mode. These measures can be taken as references for medical education reform in mainland.

OBJECTIVETo explore the clinical effects of Mobi-C cervical artificial disc replacement (CADR) and anterior cervical decompression and fusion (ACDF) in treating single cervical disc herniation.

METHODSFrom June 2009 to June 2012, the clinical data of 27 patients with single cervical disc herniation were retrospectively analyzed. There were 18 males and 9 females, aged from 30 to 62 years old with an average of 46.7 years. Of them, 12 patients were treated with CADR (CADR group) and 15 patients with ACDF (ACDF group). All patients had pain and numbness in neck, shoulder and upper limbs, and courses of disease was from 1 to 13 months with an average of 2.4 months. The data of clinical evaluation and questionnaire survey about quality of life were collected before operation, postoperative at 1 week and final follow-up. Odom criterion was used to evaluate postoperative effect. Visual analogue scale (VAS) was used to record pain levels. Neck disability index (NDI) and health questionnaire SF-36 were used to assess the quality of life.

RESULTSNo complications about nerve and blood vessel were found and the patients were followed up from 6 to 30 months, with an average of 16 months. One week after operation, 10 cases got excellent results and 2 good in CADR group; 5 cases got excellent results and 10 good in ACDF group; there was significant difference between two groups (P<0.05). At final follow-up, 10 cases got excellent results and 2 good in CADR group; 12 cases got excellent results and 3 good in ACDF group; there was no significant difference between two groups (P> 0.05). Pain of upper limbs had obviously relieved between two groups at 1 week after operation and final follow-up (P<0.05). VAS of neck and NDI in CADR group had decreased respectively from preoperative 3.58±0.79, 23.42±6.36 to 0.58±0.51, 5.42±1.68 at 1 week after operation (P<0.05); but the index in ACDF group was no obvious at 1 week after operation. At final follow-up, VAS of neck and NDI and SF-36 score were obviously improved than preoperation (P<0.05) between two groups.

CONCLUSIONMobi-C CADR retains the movement unit in the decompression segment and can quickly recover normal action for patients. Using CADR method has a good curative effect in the early phase, and the clinical effect is reliable, may improve the quality of life.

OBJECTIVETo investigate the clinical application of free superficial iliac circumflex artery skin flaps, as well as the management of donor site defects.

METHODS17 free superficial iliac circumflex artery skin flaps were applied for the traumatic defects or deformities on face, neck, foot, hand, ankle and lower leg, respectively. The donor site defects were closed directly or covered by paraumbilical island flaps.

RESULTSThe 17 flap size ranged from 5 cm x 3 cm to 19 cm x 14 cm. 16 flaps survived completely except 1 flap with partial necrosis, which was closed by free skin graft. The donor site defects were closed directly in 10 cases, and covered by paraumbilical island flaps in 7 flaps without no flap necrosis. The abdomen had a good appearance.

CONCLUSIONSGood appearance can be achieved with free superficial iliac circumflex artery skin flaps for the defects on face, neck, foot, hand, ankle and lower leg. Paraumbilical island flap can be used for the donor site defects.

AlM:To investigate the changes of retinal histology and oxidative stress in diabetic retinopathy and its reversal by pyruvate in diabetic rats.
METHODS: Eighty Wistar rats were divided into 3 groups:control group ( 20 rats ) , model group ( 30 rats ) and treatment group ( 30 rats ) . After streptozotocin ( STZ) induced diabetes mellitus in the model group and the treatment group, the treatment group received 2%pyruvate in diet and drinking. The changes of body weight and blood glucose were observed and the changes of glutathione peroxidase ( GSH-PX ) , malonie dialdehyde ( MDA) , and Na+-K+-ATPase levels of retinal tissue and retinal ultrastructure were investigated in three groups at 12wk after occurrence of diabetes.
RESULTS: Compared with control group, the body weight of the model group were significantly decreased, the activities of GSH-PX and ATP in the retina of diabetic rats were significantly lower, the MDA was signigicantly higher and significant changes occurred in retinal ultrastructure. Compared with model group, the blood glucose of the treatment group had no significant changes. However, the activities of GSH and ATP in the retina of diabetic rats were higher, the MDA was lower and the retinal ultrastructure was comparatively mild.
CONCLUSlON:Pyruvate can alleviate oxidatie stress reaction, improve the energy metabolism of retina, and delay the development of retinopathy.

Objective To compare and quantify the determinants in quantitative electroencephalogram(q-EEG) and heart rate variability power spectrum analysis(HRV-PSA) of ketamme(KTM) anesthesia for preschoolers. Methods Seventy four cases were selected and assigned into 3 groups named A(4-5 years), B(5-6 years), C(6-7 years), 22,28,24 cases in every group respectively. All cases were induced with KTM 5 mg /kg intramuscularly and changes of determinants were recorded continuously. If body movement happened, KTM would be injected with 1 mg/kg. Results On pre- anesthesia, BIS in group A was the least among 3 groups, while LF/HF and HRVI were the largest(P
