AlM: To compare the two methods for the measurement of glaucoma patients' intraocular pressure ( lOP) between Goldmann applanation tonometer ( GAT) and non-contact tonometer ( NCT) and find the laws of the two methods.?METHODS: The lOP of 108 glaucoma patients ( 206 eyes) were measured by GAT and NCT respectively.?RESULTS: ln 108 glaucoma patients, the average lOP of 206 eyes was 29. 77 ± 10. 27mmHg by GAT and 24. 59 ± 8. 58mmHg by NCT. There was significant difference between GAT and NCT (P<0. 01). The higher of lOP, the difference between GAT and NCT was greater.?CONCLUSlON: The measurement results with NCT were lower than that of GAT. The higher of lOP, the difference between GAT and NCT was greater. lt's better to measure lOP by GAT for the glaucoma patients, in order to avoid the misdiagnosis and mistreatment of glaucoma.

AlM:To evaluate the clinic efficacy of protein-free calf blood extract ophthalmic gel on healing children dry eye.METHODS: One hundred patients ( 50 patients each group) with children dry eye were divided into two groups randomly: control group was dropped 1g/L sodium hyaluronate eye drop four times per day and experimental group was dropped protein-free calf blood extract ophthalmic gel four times per day. Both groups received the depathogeny treatment at the same time. Symptom scores, Schirmer l test values, tear break-up time ( BUT ) , cornea fluorescein staining scores were recorded on the prior treatment and 30d post-treatment, then they were analyzed.
RESULTS:There were statistically significant difference (P<0. 05) for the comparison in the symptom scores, Schirmer l test values, BUT, cornea fluorescein staining scores of prior treatment and post-treatment in each groups. And there were statistically significant difference (P<0. 05) in the same items of post-treatment between the two groups.
CONCLUSlON: There is a clearly beneficial effect of protein-free calf blood extract ophthalmic gel on healing children dry eye.

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.

AIM:To observe the structural basis of ocular motility abnormalities in patients with congenital fibrosis of the extraocular muscles type Ⅰ ( CFEOM Ⅰ) due to missense mutations in the developmental kinesin KIF21A using high - resolution magnetic resonance imaging ( MRI) .
METHODS: Totally 11 affected individuals reported KIF21A mutations were correlated with MRI studies demonstrating extraocular muscles ( EOMs ) size, location, contractility, and innervation. EOMs and the motor nerve in the orbits were imaged with T1 weighted in a triplanar scan using a dual-phased coils with 2. 0mm thick. Motor nerves were imaged at the brainstem using head coils and 3D-FIESTA with 0. 6-mm thick.
RESULTS: Patients with CFEOM Ⅰ exhibited different degrees of hypoplasia of oculomotor nerve, the abducens nerve and the trochlear nerve were also affected, of which 8 cases of orbital section could see the signal of abnormal nerve dominated by oculomotor nerve to lateral rectus. The both sides of six EOMS in all patients exhibited variable atrophy and abnormal bright internal signal on T1 imaging, particularly severe for the superior rectus and levator muscles.
CONCLUSION: High - resolution MRI can directly demonstrate pathology of motor nerves,affected EOMs, and ‘Pulley' hypoplasia caused by CFEOM Ⅰ due to mutations in KIF21A,and these findings suggest that the neuronal hypoplasia is the etiological factor of CFEOM.
