Objective To evaluate the effects of different doses of propofol infusion on real-time monitoring of recurrent laryngeal nerve. Method 30 ASA Ⅰ-Ⅱ patients who underwent thyroid gland surgery were given propofol intravenously in different concentrations. BP, HR and real-time monitoring of recurrent laryngeal nerve were recorded with the propofol dosage varying from 3 to 6, 9, 12, 15, 18?g/(kg?min). Results The amplitude of recurrent laryngeal nerve reflex had no change with different doses of propofol infusion. The HR and BP were elevated with low doses of propofol infusion, but there were no changes when propofol concentration was 15 or 18?g/(kg?min). Conclusion Propofol infusion i.v. does not interfere with real-time intraoperative monitoring of recurrent laryngeal nerve, and it does not inhibit the action potential of recurrent laryngeal nerve, but can effectively decrease the cardiovescular reaction.

Objective To discuss the clinical value of the "three-step" diagnostic routine in the diagnosis of cervical high-grade lesions. Method The women with the abnormal thinprep cytology test (TCT) underwent colposcopy and biopsy,the pathobiology result was the diagnostic standard. The sensitivity and specificity of the cervical high-grade lesions was calculated. Results The identify rate of the cervical high-grade lesions from the abnormal TCT was 22.3% (340/1524), the sensitivity was 27.1% (92/340), the specificity was 97.5% (1154/1184). The sensitivity of colposcopy was 47.9% (163/340), the specificity of colposcopy was 96.4% (1141/1184). Conclusion TCT with high sensitivity is used for preliminary screening, the colposcopic examination is used to pinpoint and evaluate the lesions,the detection rate and accuracy of cervical high-grade lesions can be improved.

Objective To observe effects of propofol versus urapidil on perioperative hemodynamics in patients with gallbladder opera-tion during tracheal extubation. Methods From 2010 January to 2012 December, 128 patients who were diagnosed by color B ultra /CT and then underwent gallbladder selective operation (ASAⅡ~IV) were selected, and they were divided into the propofol group (n=64) and the urapidil group (n=64). At the end of operation, patients of the two groups were given intravenous injection of propofol 1. 5 mg/kg and ura-pidil 2. 5mg/kg which were diluted with normal saline to 8 mL respectively. Sputum suction immediately after medication, and then wiped out the endotracheal tube and gave oxygen masks for 10 min. Record the systolic/diastolic blood pressure ( SBP/DSP) , heart rate ( HR) , pH, PaO2 , PaCO2 and SaO2 under double blind trial before induction, after medication, at the time of sputum suction, at the time of extuba-tion, 5 min after extubation and 10 min after extubation. At the same time, agitation during the extubation period and patients awake time were recorded. Results After extubation, cough (4. 7% vs. 26. 6%), agitation (3. 1% vs. 17. 2%) and glossoptosis (12. 5% vs. 21. 9%) in propofol group was significantly lower than urapidil group (P<0. 05). SBP/DSP and heart rate of propofol group and urapidil group were significantly increased (P<0. 05) before induction, after medication, at the time of sputum suction, at the time of extubation, 5 minafter extubation and 10 min after extubation. The recovery time of propofol group and urapidil group were of no significant differences (P>0. 05). During perioperation extubation, there was no significantly difference in terms of changes of pH, PaO2, PaCO2 and SaO2 be-tween the groups (P>0. 05). Conclusion Propofol is better than urapidil in preventing adverse effect of extubation for patients with gall-bladder operation, and it will not affect the recovery time of patients.

Objective To investigate the effect of different bone cement volume injected after vertebroplasty on stress distribution of the upper and lower endplates of the injured vertebra in the flexion and extension positions by finite element analysis.Methods Two patients with osteoporotic compression fractures of L2 vertebral body were chosen.Bone cement volumes of 25％ and 50％ were respectively injected into the fractured vertebral body bilaterally.Pre-and post-operative finite element models of fractured and adjacent vertebral bodies were developed after extracting the CT data.Stress changes at L2 superior-and inferior-vertebral endplates were observed in the vertical,flexion,and extension loading.Results Stress at the upper and lower endplates of the fractured vertebra increased after bone cement injection and more increase was observed in 50％ bone cement group than in 25％ bone cement group.In the neutral position,the stress mainly concentrated at posterior vertebral body,with stress of the upper endplate improving from 0.91 × 106 N · mm to 0.93 × 106 N · mm and stress of the lower endplate from 0.98 × 106 N ·mm to 1.03 × 106 N · mm.In the anterior flexion,the stress mainly concentrated at anterior vertebral body,with stress of the upper endplate improving from 4.44 × 106 N · mm to 5.55 × 106 N · mm.In the posterior extension,the stress mainly concentrated at medial vertebral body,with stress of the upper endplate improving from 21.95 × 106 N · mm to 22.10 × 106 N · mm and stress of the lower endplate from 30.60 ×106 N · mm to 30.88 × 106 N · mm.The finite element model revealed stress at the upper and lower endplates was higher in the anterior flexion and posterior extension than in the neutral position,while in the anterior flexion the stress was comparatively higher.Conclusions A small amount of implanted bone cement act no evident effect on stress distribution of the upper and lower vertebral endplates.However,the stress changes are significant as cement volume reached up to 50％,especially in the flexion position,as may suggest an enhanced risk of adjacent intervertebral disc degeneration and adjacent vertebral body fractures.

Objective To compare the effect of insulin pump continuous subcutaneous insulin (CSII) and multiple subcutaneous insulin (short-acting insulin before meals + glargine,MSII) for the short duration of type 2 diabetes mellitus (T2DM) patients.Methods Fifty-two newly diagnosed T2DM patients were randomly divided into CSII(n =29) and MSII(n =23) group.Patients in CSII group were given insulin pump continuous subcutaneous plus metformin.And patients in MSII group were given insulin by multiple subcutaneous insulin injection plus metformin.The treating periods was 2 weeks and followed up one month.Results The periods from point of insulin injection to blood glucose back to normal level in CSII group was (4.70 ±2.01) d,shorter than that in MSII group(6.90 ± 1.50) d,and the difference was significant(t =2.056,P ＜0.05).The levels of C peptide in two hours postprandial before and after treatment in CSII group were (4.24 ± 0.25) ng/L,(6.29 ± 0.56) ng/L,and (3.20 ±0.11) ng/L and (7.33 ±0.41) ng/L respectively in MSII group.The levels of C peptide in two hours postprandial after treatment were higher than that of before treatment in two groups (t =2.018,2.436 respectively,P ＜0.05),but there were no significant differences between two groups(t =0.985,P ＞ 0.05).Nineteen cases (65.5％) in CSII group were off insulin treatment in one month,and 9 cases (39.1％) in MSII group.There were significant differences in two groups(x2 =5.11,P ＜0.05).Conclusion The two treatment plans can make the improvement in terms of glucose control.However,CSII plan showed more effective than MSII.

Objective To determine the radiographic feasibility of oblique lumbar interbody fusion (OLIF) corridor to treat lumbar disease at each lumbar disc level,including the corridor's numerical value and the influence of diaphragmatic crura and aorta abdominalis.Methods A retrospective CT study was conducted on 110 patients (including 69 males and 41 females,average age 47.95 years,range 16-83 years) that continuously collected and analyzed in the PACS system.The oblique corridor was defined as the area between the left lateral border of the aorta abdominalis(or iliac artery) and the right lateral border of the left psoas.The distances and angles of L1-2,L2-3,L3-4 and L4-5 levels were measured.Whether the change of diaphragmatic crura and aorta abdominalis affected the building of the corridor was also observed.Results The mean distances of oblique corridor to the levels of L1-L5 discs were:L1-2 15.90 mm,L2-3 14.82 mm,L3-4 17.57 mm,L4-5 11.16 mm.At the levels of L1-2 and L3-4,all of the images could build the corridor.But there were only 97.27％ images allowing operation at both L2-3 and L4-5,and the other 3 cases couldn't build the corridor since the aorta abdominalis was very close to psoas,and the distance was almost 0 mm.The max mean distance was 36.79 mm at L3-4 level.The mean angles were:L1-2 36.98°;L2-3 37.76°;L3-4 40.96°;L4-5 37.85°.The significant difference was at L3-4,ranged from 13.09 to 61.93°.The level of the aortic bifurcation was from the lower third of the L3 vertebral body to the middle third of the L5 vertebral body.The levels of left diaphragmatic crura's ending point in the lumbar was divided into four groups:1) Group L1 vertebral body level:the level at L1 vertebral body and above,5 cases (4.55％);Group L1-2 disc to L2 vertebral body level:at L1-2 disc and L2 vertebral body,67 cases (60.91％);Group L2-3 disc to L3 vertebral body level:at L2-3 disc and L3 vertebral body,36 cases (32.72％);Group L3-4 disc to L4 vertebral body level:at L3-4 disc and L4 vertebral body,2 case (1.81％).Conclusion The OLIF corridor can be built successfully at L1-2 and L3-4.However,it may be difficult at L2-3 and L4-5 for some patients due to the aorta abdominalis which is too close to psoas.The angles of L1-L5 levels were similar.While the left diaphragmatic crura was mainly impact the corridor insertion at L1-2 and L2-3.And the level of the aortic bifurcation was mainly located at the upper endplate of L4 to the L4-5 disc (87％).
