MethodsThe clinical data of 85 patients of thyroid disease undergoing 126 lobectomies from Jan 2010 to Jan 2011 were retrospectively analyzed.All patients undergone accurate thyroid lobectomy with accurate envelop anatomic dissection,skeletonized blood vessels. Recurrent laryngeal nerve was all dearly exposed.ResultsNo-bleeding surgical area was achieved.The RLN was exposed.Unilateral temporary RLN injury occurred in 2 cases.The rate of RLN injury was 1.59%(2/126). There was no bilateral and perpetual RLN injury.ConclusionsCarrying through the accurate thyroid lobectomy,the incidence of RLN injury is low.

Objective To investigate the glial activation in the spinal cord in a rat model of persistent postoperative pain. Methods Forty-eight adult male SD rats weighing 200-250 g were randomly divided into 2 groups ( n = 24 each): group Ⅰ sham operation (group S) and group Ⅱ persistent postoperative pain. Persistent postoperative pain was evoked by skin/muscle incision and retraction (SMIR) as described by Flatters. Pawwithdrawal threshold to yon Frey hair stimulation was measured before operation (baseline) and at 1, 3, 12, 22and 32 d after establishment of the model. Four animals were sacrificed at each time point and lumbar segment of the spinal cord was removed for determination of expression of glial fibrillary acidic protein (GFAP) in the astrocytes by immunofluorescence histo-chemistry assay. Results The mechanical threshold started to decrease at 1 d after establishment of the model, and peaked at 12 d after establishment of the mode. Immunofluorescence histochemistry assay demonstrated that GFAP expression in the dorsal horn was significantly increased at 3 d after estabhshment of the model and reached the peak at 12 d and was maintained at the high level until 22 d after establishment of the model. Conclusion Glial activation is involved in the mechanism of persistent postoperative pain evoked by SMIR.

ObjectiveTo assess the effects of dopamine,dobutamine and norepinephrine on the P(g-a)CO2 and superior mesenteric blood flow in septic shock.MethodsRabbit septic shock model was established by challenging with intravenous injection of lipopolysaccharides from Escherichia coil(2 mg/kg).The rabbits with septic shock were randomly assigned to 3 groups-dopamine group(n = 8),dobutamine group(n = 8) and norepinephrine group(n = 8).Apart from volume resuscitation with normal saline solution [20 ml/(kg· h)],dopamine[5μg/(kg·min)],dobutamine[(5μg/(kg·min)]and norepinephrine [(1μg/(kg·min)]were infused in dopamine group,dobutamine group and norepinephrine group respeclively.Cardiac index(CI) and superior mesenteric blood flow index(SMBFI) were continuously monitored by doppler flowrneter.Gastric mucosal PCO2 was evaluated by gas tonometry every 10 min.Arterial and venous blood gas analyses and lactate levels were measured every 1 h.ResultsMAP,CI,and SMBFI significandy decreased and P(g-a) CO2 increased after lipopolysaccharides infusion in three groups.After 2-hour treatment,MAP in norepinephrine group[(70 +3) mm Hg]was higher than that of dopamine group[(66±4) mm Hg]and dobutamine group[(65±4) mm Hg](P <0.05).SMBFI in norepinephrine group [(18.7±2.9) ml/(kg·min)]was higher than that of dopamine group[(16.2±1.6) ml/(kg·min)]and dobutamine group[(15.8±1.9) ml/(kg·min)](P<0.05).P(g-a) CO2 in norepinephrine group [(30±6) mm Hg]was lower than that of dobutamine group[(23±5)mm Hg](P<0.05).Condnsion As an adjuvant therapy of volume resuscitation,norepinephrine is more effective than low dose dopamine and dobutamine in improving splanchnic perfusion.

Objective To explore propofol dosage difference between in morning and at after-noon undergoing gynecological clinic short operation.Methods One thousands and nine hundred fifty eight female patients,aged 1 6-50 yr,of ASA physical status Ior II,undergoing gynecology clinic short operation,according to the operation time,were divided into two groups,Group morning (8:30-1 1:30,n =1047)and group afternoon (14:00-1 7:00,n =91 1).Each patient was intravenously injected fentanyl 0.01 μg/kg,and then propofol 2.5 mg/kg.When the observer’s assessment of alertness/se-dation (OAA/S)scores reached 0 score,the operation began.If the body moved,the surgery was stopped and 25 mg propofol was intravenously injected quickly.After 10 seconds observation,if the body movement existed,25 mg more propofol was performed,until the movement disappeared.Re-cord patients’year,height,weight,body mass index,and the heart beat,blood pressure of pre-op-eration,the number of times of cervix uteri expansion per vagina,the history of labor per vagina,the total dosage of propofol and the time length of sedation.Results The dosage of group afternoon (1 52.1 6±65.90)mg was higher than group morning’s (135.69±37.67)mg (P <0.05).There was no significant difference of time lengths of sedation between the two groups.Additional use of propofol in the afternoon group 387 (42.5%)was higher than group morning’s 1 99 (23.5%)(P <0.05).Conclusion In gynecological clinic short operation,the propofol dosage in afternoon was higher than that in the morning group.But the sedation time length in afternoon was not longer than that in the morning.

Objective To study the histologic changes of arteries dilation under different hydraulic pressure. Methods Right carotid arteries were dilated by using hydraulic method with different pressures (40, 80, 120 kPa) normal saline. The endothelial cells, internal elastic membrane (IEM), smooth muscle (SM) and adventitia of the arteries were studied under microscope. The arterial calibre, thickness of tunica intima and smooth muscle were measured under TJTY-300 automatic medical photograph analyser. Results 1) The calibre of the dilated arteries increased. 2) When the pressure was 40 kPa, there were mild injuries of endothelial cells, internal elastic membrane and smooth muscle; all the injuries recovered to normal 1 week later. 3) The degree of injury of the individual layers of the arteries gradually aggravated as the pressure raised up to over 80 kPa. The repair also required long periods of time and was found imperfect. The proliferation of fibres of connective tissues took place one week later. Conclusion 1) Blood flow could be increased after hydraulic dilation of the artery, and the strength of washing away the small thrombosis over the site of anastomosis could be increased. 2) For safety, the hydraulic pressure of arterial dilation should be better kept within 40 kPa.

Objective To observe the patency and the rate of arterial spasm in different time periods following segmental hydrolic dilation during the course of tissue transplantation; also the influence of arterial dilation to arterial structure was studied with histological examinations. Methods Fifty seven patients with thumb or finger defects were treated with thumb reconstruction using thumb nail flap free transplantation in 41 cases, thumb reconstruction using free transplantation of the second toe in 6 cases and 10 cases had finger reconstruction using the second and third toe free transplantation. Following complete tissue isolation, and prior to vascular anastomosis, heparin+normal saline was injected into the dorsal pedal artery, the first metatarsal artery and the digital artery of the big toe or the second for segmental dilation with the pressure of 300 mmHg. The dorsal pedis arteries were taken for histologic studies after hydrolic dilation. Results 1)The temperature of transplanted tissues were 0.16 ℃ higher than the health side. 2)The immediate arterial patency rate was 100% after anastomosis and the rate of spasm was 0. Vascular crisis took place in one case 24 hours after the operation, and was relieved after removal of the hematoma. There was one failure due to the extensive thrombosis formation in the capillaries. 3)Histologic study showed: there were 15% of the arterial endothelium exfoliated following hydraulic dilatation, resulting in looseing of the internal elastic membrane, a basically normal muscular layer of different thickness; without hydraulic dilatation, 7% of the arterial endothelial cells exfoliated, with homogeneous thickness of the internal elastic membrane and intact muscular layer. Conclusion 1)Segmental hydrolic dilation is one of the effective methods to prevent and treat vascular spasm and it is a safe and effective method to increase the successful rate of free tissue transplantation. 2)Hydrolic dilation within a certain range(300 mmHg) had no obvious effect on arterial structure.
