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 evaluate the influence of complete or incomplete revascularization on the life quality of elderly patients with multivessel coronary artery disease. Methods:The study retrospectively analyzed the clinical data and the quality of life assessment result in the elderly patients with multivessel coronary artery disease,who were over 60 years,underwent percutaneous coronary intervention(PCI) procedure from June 2003 to December 2004 in our center,and followed-up for 2 years with the 36 items short form health survey(SF-36).Results:All domains,except that for mental health,assessed by the SF-36 showed significantly higher scores after revascularization by PCI,and the scores in completely revascularized patients were higher than those in incompletely revascularized patients. Conclusion:PCI can significantly improve the quality of life and the improvement is better with complete than with incomplete revascularization.

Objective: The main purpose of percutaneous coronary intervention(PCI) is to improve patients' quality of life.Many studies focus on the efficacy of PCI for angina relief,but rarely on the improvement of quality of life after PCI.We aim to investigate the quality of life in patients with coronary heart disease(CHD) 2 years after coronary stent implantation.Methods: A total of 457 CHD patients underwent coronary stent implantation,their quality of life investigated with The Short Form 36 Health Survey Questionnaires(SF-36) before and 2 years after the operation.Results: The results of various dimensions of SF-36 before and 2 years after the operation were as follows: physical function(PF)(56.47?26.05 vs 68.20 ? 20.18,P 0.05).Conclusion: Coronary stent implantation could significantly improve the long-term(2-year) quality of life of patients with coronary heart disease.

unprocessed sample. The statistics analysis showed that the emodin contents in raw Rhizoma Polygoni Cuspidati were significantly different from those in the different processed products of Rhizoma Polygoni Cudpidati. Conclusion: The processing temperature and time, wine, vinegar and salt could make the contents of emodin in Rhizoma Polygoni Cuspidati change in different degree.

Objective To compare the curative effects of lumbar traction in supine position with hip flection and extension for prolapse of lumbar intervertebral disc (PLID).Methods 84 PLID patients were all treated by lumbar traction in supine position. But, group A (42 cases) with hip flection and group B (42 cases) with hip extension. Before and after three weeks therapy, all patients were assessed by Fairbank JC index and Visual Analogue Scales (VAS) to observe the symptom and pain condition.Results The scores of Fairbank JC index and VAS scale of the patients in group A were significantly lower than those in the group B (P<0.001).Conclusion Lumbar traction in supine position with hip flection for the PLID can obviously promote the curative effects.

Proteins extracted from two varieties of Chinese roses leaves were separated by two- dimensional polyacrylamide gel electrophoresis (2-DE) with immobilized pH gradient (IPG). Many difference proteins were isolated with molecular weights ranging 10-30 kDa and pI5-6. Three proteins of high levels observed in a gel were excised and identified using peptide mass fingerprinting and MS-MS. A summary of the identified proteins and their putative functions are presented. They are identified as eIF-5A、LEA protein and Hsp17. 5. Functions of these proteins in plant tolerance to high temperature were discussed.

Objective To evaluate the effects of TENS on metatarsus plantar flexion and inversion in stroke patients,and to explore its mechanism.Methods Thirty-two stroke patients with gastrocnemius spasticity were randomly divided into a control group (n=16) and a TENS group (n=16).All patients were treated with foot sup- ports,neurodevelopmental and manipulation therapies.In addition,the TENS group received TENS on the anterior tibialis,peroneus longus and brevis muscles.All patients were assessed in terms of their Chinese stroke scale(CSS) and H reflex scores before and after therapy.Results Compared with those in the control group,the H reflex scores in the TENS group were obviously decreased,while H reflex latency was prolonged and H/M was reduced. Gait in the TENS group was evidently improved.Conclusion TENS is an effective therapy to decrease gastrocnemi- us spasticity and to improve the gait of stroke patients.
