AlM:To explore the suitable conditions in rapid model of corneal neovascularization ( CNV ) after thermal burn under different constant temperature in rabbit.
METHODS: Total 45 New Zealand white rabbits were divided randomly into five groups ( A, B, C, D, E ) . A groups:100℃ ( n = 10 ) , B groups: 200℃ ( n = 10 ) , C groups:300℃ ( n=10 ) , D groups: 400℃ ( n=10 ) , and E groups:control group ( n=5 ) . All left eyes of rabbits in A,B,C,D groups were induced corneal neovascularization by constant temperature burning device. The growth of CNV was observed by slit lamp microscope and the area of CNV were recorded on 4 th , 7 th , 14 th , 30 th days postoperatively. SPSS 19. 0 statistical package was used for data analysis, and the data was recorded by mean ± standard deviation. Comparison by analysis of variance was made by repeated measures in the area of neovascularization at each time point in groups. Statistical tests were considered significantly when P values were less than 0. 05.
RESULTS:On postoperative 4 th , 7 th , 14 th , 30 th days: no neovascularization was found after corneal thermal burn in A group, but only a few nebula left (n=2);the area of CNV were (9.16±1.45)mm2, (37.73±5.49)mm2, (62.44± 7. 54 ) mm2 , ( 40. 28 ± 7. 39 ) mm2 in B group respectively;and (11.45±1.04)mm2, (44.51±4.64)mm2, (66.13±4.13)mm2, (43.04±2.33)mm2 in C group respectively; and (13.23± 0.86)mm2,(47.26±4.59)mm2,(67.57±4.56)mm2,(45.59± 4. 44 ) mm2 in D group respectively, and part corneal carbide ( n = 4 ) was observed as well as corneal perforation ( n= 6 ) were found on 3d in D group. No neovascularization was found in normal control group. Comparison of the areas of CNV at each time point between groups was statistically different, P < 0. 05. Statistical differences were found among B, C, D groups, P<0. 05.
COCLUSlON:ln 4 to 7d, the higher the temperature is, the more the neovascularization area of CNV are. lt has no significant difference in 14 to 30d. But corneal carbide and corneal perforation are often found in 400℃ group, so its modeling failure rate is high. lt is between 200℃ and 300℃ that repeatability and uniformity of the corneal neovascularization model of rabbit are superior.

BACKGROUND:Percutaneous vertebroplasty, percutaneous kyphoplasty and expandable pedicle screw fixation can treat primary osteoporotic thoracolumbar fractures. The three methods have their own advantages and disadvantages. OBJECTIVE:To investigate the methods and clinical effects of primary osteoporotic thoracolumbar fractures. METHODS:Clinical data of 61 patients with primary osteoporotic thoracolumbar fractures were col ected and retrospectively analyzed. Perioperative preparation must be done. Al patients were treated by percutaneous vertebroplasty, percutaneous kyphoplasty and expansive pedicle screw fixation. We recorded Visual Analogue Scale (VAS) and the Oswestry Disability Index (ODI) before treatment, 3 months after treatment, as wel as sagittal index (SI) and Cobb angle of vertebral fracture before treatment, 3 days and 3 months after treatment. RESULTS AND CONCLUSION:(1) Al cases were fol owed up for 12-18 months. (2) There was no significant difference in VAS scores, ODI, SI and Cobb angle of vertebral fracture among the three groups of patients preoperatively. (3) At 3 months after treatment, there were significant differences in VAS scores and ODI in the three groups as compared with that preoperation (P<0.05). However, no significant difference in VAS and ODI was determined among intergroup comparison (P>0.05). (4) SI and Cobb angle of vertebral fracture were significantly increased;the difference was statistical y significant (P<0.05). The efficacy was similar between the percutaneous kyphoplasty and expansive pedicle screw fixation groups (P>0.05), and was better than the percutaneous vertebroplasty group (P<0.05). (5) Three kinds of treatment can effectively restore the vertebral height and intensity, relieve pain and stabilize the spine, and no significant vertebral compression was found in the short term. However, restoration of postoperative vertebral height was better in percutaneous kyphoplasty and expansive pedicle screw fixation groups than in the percutaneous vertebroplasty group. In view of their respective indications, advantages and disadvantages, the key point of raising therapeutic effect was to choose appropriate surgical procedures.

Objective To research whether serum hepatocyte growth factor (HGF) level increases in ischemic stroke and hemorrhagic stroke, and explore the relationship between the serum HGF level and stroke recurrence. Methods We studied a total of 92 consecutive acute stroke patients who had been admitted to hospital within 24h of onset from 6 participating hospitals in Xi'an from January 2000 to May 2004. All patients were divided into ischemic stroke group and hemorrhagic stroke group according to the results of brain computed tomography (CT) scan or MRI on admission. Patients in stroke groups were divided into recurrent group and non-recurrent group. Healthy volunteers or patients without cerebrovascular diseases comprised the control group. Stroke and control groups were strictly matched with 1∶1 ratio. The patients were followed up for 4 years. Serum HGF was tested with enzyme-linked immunosorbent assay (ELISA). Results Serum HGF of stroke patients was significantly higher than that of control group (P<0.05). The serum HGF level in recurrent group was higher than that in non-recurrent group of ischemic patients, and there was no significant difference in hemorrhagic ones. Conclusion These results indicate that serum HGF may be used as a diagnostic marker for stroke, and serum HGF level is helpful in predicting the recurrence of ischemic stroke.

Objective: To observe the changes of heart rate and the contents of angiotensin Ⅱ(AngⅡ) in blood plasma in ventricular tachycardia(VT) rats with electro-acupuncture(EA) on ‘daling’(PC7). Methods: 40 SD rats were randomly divided into normal, model, treatment and control groups with 10 cases in each. VT model was duplicated by inject CsCl in femoral vein. To observe the rats’ electrocardiogram (ECG) and record their heart rates. EA was applied to‘daling’ (PC7) on treatment group and applied to‘Taiyuan’ (LU9) on control group for 5 minutes. Then, we detected the contents of AngⅡ in the rats’blood plasma respectively. Results: The heart rate and contents of AngⅡin rat increased obviously in model group were (547?30) time/min and (353.21?49.12)pg/mL). They restored to the normal state after EA ‘daling’ (PC7) are(474?25)time/min and(268.44?47.49)pg/ mL.But the effect was not obvious in ‘Taiyuan’ (LU9). Conclusion VT rat heart can be prompted to restore to the normal state after EA ‘daling’(PC7); AngⅡ played an important role in VT.

AIM: To evaluate the accuracy of central conreal thickness ( CCT ) using EX500 Excimer Laser workstation (EX500) in laser in situ keratomileusis (LASIK) patients.METHODS:The CCT of 120 eyes (63 patients) who had LASIK between January 2013 and June 2013 were measured by A- scan and EX500. Three groups were classified: >550μm, 500 ~550μm, <500μm according the CCT value of A-scan. The CCT were measured again by corneal flap creating by moria SBK microkeratome. The thickness of the corneal bed stroma were measured by A-scan and EX500 after keratomileusis. All outcomes were analyzed with paired t test.
RESULTS: The average preoperative CCT value was 527. 9±34. 3μm measured by A-scan, 528. 5±34. 6μm measured by EX500. There was no significant difference between these two measurements (t=1. 736, P=0. 085). In group which CCT >550μm, the average preoperative CCT value was 571. 4±17. 3μm measured by A-scan, 572.7±15. 7μm measured by EX500. There was no significant difference between these two measurements (t=1. 857, P=0. 072). In group which CCT 500 ~ 550μm, the average preoperative CCT value was 523. 4±13. 1μm measured by A-scan, 524. 2±12. 4μm measured by EX500. There was no significant difference between these two measurements ( t=1. 934, P = 0. 058 ). In group which CCT <500μm, the average preoperative CCT value 484. 5±9.8μm measured by A-scan, 483. 7±8. 9μm measured by EX500. There was no significant difference between these two measurements (t=1. 395, P=0. 174). The average CCT value after corneal flap lifting was 401. 3 ± 34. 2μm measured by A-scan, 393. 4±38. 9μm measured by EX500. There was a significant difference between these two measurements ( t = 6. 669, P = 0. 000 ). The average thickness of the corneal bed stroma value after keratomileusis was 332. 6±38. 3μm measured by A-scan, 307. 3 ± 37. 1μm measured by EX500. There was a significant difference between these two measurements ( t=17. 165, P=0. 000).
CONCLUSION: There is no significant difference between preoperative CCT value measured by A-scan and EX500. After corneal flap lifting and keratomileusis, the CCT value measured by EX500 is smaller than measured by A-scan.
