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.

Objective To investigate the pubertal growth patterns and anthropometric characteristics of the patients with adolescent idiopathic scoliosis(AIS) by anthropometry measurements. Methods The anthropometric data of 256 AIS girls were collected. The mean age of diagnosis was 14.1 years old(from 12 to 16 years old). The children with more than 10 degree of the scoliosis angle at coronal level were diagnozed as AIS. The control group consisted of 462 age-matched health girls. Four variables were measured: height, sitting height, arm span and menstrual states. Height and sitting height were adjusted using Bjure formula to make up the height loss from spinal deformity. The above variables were analyzed between AIS group and the controls. Results There were no differences in the composition of age between two groups. There were no significant differences in height,sitting height and arm span between the 256 cases of AIS girls and the 462 controls. However, the corrected height and sitting height were significantly higher in AIS than those of the controls. The menstrual onset time was earlier in AIS than that in controls. There were no statistical differences in corrected height, corrected sitting height and arm span between AIS girls and the controls at the age group of 12 years old. On the contrary, the AIS girls showed shorter uncorrected height than the controls did at this age. However, the scoliotic girls were found in the corrected height, the corrected sitting height and the arm span significantly taller than the controls between ages of 13 and 15 years. There were significant differences in corrected height and corrected sitting height between AIS girls and the controls at the age of 16 years old, while no difference were found in the variables of height, sitting height and arm span. Conclusion There is an abnormal growth pattern in AIS during pubertal growth spurt, which may be related to the pathogenesis of AIS.

BACKGROUND:Open reduction is general y not advocated for the treatment of children clavicle fracture, because the thick and tough periosteum remains intact and attached by the ligament attachment. In clinic, twin-ring external fixation and simple suspension are commonly used, but there is no reliable basis on which method can get better effect.
OBJECTIVE:To compare the stability of twin-ring external fixation and simple suspension for the treatment of children clavicle fracture.
METHODS:The patients with children clavicle fracture and treated by twin-ring external fixation and simple suspension were selected from June 2008 to December 2012, including 17 patients treated with simple suspension and 22 patients treated with twin-ring external fixation. The X-ray film examination was performed regularly to observe the fracture healing and shoulder function.
RESULTS AND CONCLUSION:The 17 patients treated with simple suspension had good healing;three cases had gap between fracture ends at 1 week after treatment, and re-suspension to increase the height and final y two fracture ends contacted in one case;for the other two cases, there was stil gap between fracture ends, and changed for twin-ring external fixation, the fracture ends contacted. Al the 22 patients in the twin-ring external fixation group obtained healing;five cases had performance of upper extremity neurovascular compression on the fracture side after fixation;after releasing, three cases had recovery, and two cases were treated with simple suspension, the fracture ends began to contact;six cases had armpit redness;four cases had early sleep difficulties;two cases had gap between fracture ends at 1 week after treatment, and after re-adjust, the fracture ends contacted in two cases. The results showed both two methods could not cause appearance deformity, and both could get healing. The simple suspension fixation is easy to operate with reliable effect, and it is comfortable which make it easy to accept by the children, it has the advantages of early for functional exercise, less tissue damage, does not affect the blood supply;the twin-ring external fixation is easy to compress the axil ary arteries and nerves on both sides, thus resulting in upper extremity swel ing, numbness and skin redness, and it can cause discomfort night sleeping and poor comfort which is not easy for children to accept. But, no matter what method we take, the review after 1 week, as wel as the line between proximal and distal part and the contact between fracture ends is stil important.
