5.Study on ultrasonic pachymetry on eyes
Journal of Practical Medicine 2002;435(11):18-20
Ultrasonic pachymetry was carried out in 300 eyes of normal, myopic, and senile cataract patients with Alcon Surgical Pachymeter. The mean central corneal thickness was 0.527mm+/- 0.034mm. Corneal thickness wa significantly correlated with age, axial length, and sex. No statistical correlation was found between corneal thickness and the right or left eyes, corneal curvature, and ocular tention (within normal range). Pachymetric results were consistent if a good applanation of the probe occurred. Thus, reliable data could only be obtained by skilled user.

8.Images and parameters of lower extremity arteries by Doppler ultrasound in normal group subjects
Journal of Practical Medicine 2005;505(3):21-23
In this study the Doppler ultrasound method has ben used for investigating the lower extremity arteries in normal group subjects.After passing through the clinical examination for exclusion purpose, 30 normal subjects were involved in Doppler ultrasound examination. Result: Parameters of arteries such as peak systolic flow velocity (Vp), peak flow velocity of reverse flow component (Vr), transversal diameter, before-after diameter were presented, which will be databases for diagnostic lower extremity artery diseases.

9.Ultrasonic measurement of biparietal diameter in combining with analytical computer for determining fetal age
Journal of Practical Medicine 2003;425(5):14-16
660 times of measurement of biparietal diameter in combining with analytical computer were performed on 74 female subjects of 16-42 week age of pregnancy (9 times for each subjects) to determine the fetal age. Results showed a close relation of biparietal diameter and fetus age. The speed of growth of biparietal diameter was high initially then lower gradually, with the age of 16-30 weeks, BD grown up 3 mm each week, and with the age of 31-37 weeks: 2 mm and 38-40 weeks: 1 mm

PURPOSE: To evaluate the effect of dry eye on the corneal thickness measured by Orbscan and ultrasonic pachymetry. METHODS: The central corneal thickness was measured by both ultrasonic and Orbscan pachymetry in 30 eyes with dry eye (dry eye group) and in 30 eyes of normal subjects (control group). Dry eye was diagnosed when a Schirmer test result was less than 10 mm (after topical anesthesia) and the test for tear osmolarity was also performed. RESULTS: Tear osmolarity was 364.4+/-42.9 mOsm/L in dry eye group and 337.8+/-34.5 mOsm/L in control group. It was significantly higher in dry eye group than in the control group (p=0.011). Mean central corneal thickness measured by Orbscan pachymetry was 547.5+/-27.3 microgram in dry eye group and 562.0+/-20.4 microgram in the control group. It was significantly thinner in dry eye group than in the control group (p=0.023). Mean central corneal thickness measured by ultrasonic pachymetry was 535.7+/-27.2 microgram in dry eye group and 547.6+/-20.1 microgram in the control group with out significant difference between the two groups (p=0.059). CONCLUSIONS: The corneal thickness measured by ultrasonic pachymetry is less affected by dry eye compared to that measured by Orbscan pachymetry.
