AIM:To verify the performance of a lesion size measurement system through a clinical ***:Our proposed system,which consists of a conventional endoscope,an optical device,an optical probe,and a personal computer,generates a grid scale to measure the lesion size from an endoscopic *** width of the grid scale is constantly adjusted according to the distance between the tip of the endoscope and lesion because the lesion size on an endoscopic image changes according to the *** shape of the grid scale was corrected to match the distortion of the endoscopic *** distance was calculated using the amount of laser light reflected from the lesion through an optical probe inserted into the instrument channel of the *** endoscopist can thus measure the lesion size without contact by comparing the lesion with the size of the grid scale on the endoscopic image.(1)A basic test was performed to verify the relationship between the measurement error eM and the tilt angle of the endoscope;and(2)The sizes of three colon polyps were measured using our system during *** sizes were immediately measured by scale after their ***:There was no error atα=0°.In addition,the values of eM(mean±SD)were 0.24±0.11 mm(α=10°),0.90±0.58 mm(α=20°)and 2.31±1.41mm(α=30°).According to these results,our system has been confirmed to measure accurately when the tilt angle is less than 20°.The measurement error was approximately 1 mm in the clinical ***,it was concluded that our proposed measurement system was also effective in clinical ***:By combining simple optical equipment with a conventional endoscope,a quick and accurate system for measuring lesion size was established.

AIM: To examine the influence of lipoprotein lipase (LPL) gene polymorphism in ulcerative colitis (UC) patients. METHODS: Peripheral blood was obtained from 131 pa- tients with UC and 106 healthy controls for DNA extrac- tion. We determined LPL gene polymorphisms affecting the enzyme at Ser447stop, as well as HindⅢ and Pvu Ⅱ polymorphisms using PCR techniques. PCR products were characterized by PCR-RFLP and direct sequencing. Polymorphisms were examined for association with clini- cal features in UC patients. Genotype frequencies for LPL polymorphisms were also compared between UC patients and controls. RESULTS: In patients with onset at age 20 years or younger, C/G and G/G genotypes for Ser447stop poly- morphism were more prevalent than C/C genotype (OR = 3.13, 95% CI = 0.95-10.33). Patients with H+/- or H-/-genotype for HindⅢ polymorphism also were more nu- merous than those with H+/+ genotype (OR = 2.51, 95% CI = 0.85-7.45). In the group with H+/+ genotype for HindⅢ polymorphism, more patients had serum triglyc- eride concentrations over 150 mg/dL than patients with H+/- or H-/- genotype (P < 0.01, OR = 6.46, 95% CI = 1.39-30.12). Hypertriglycemia was also more prevalent in patients with P+/+ genotypes for PvuⅡ polymorphism (P < 0.05, OR = 3.0, 95% CI = 1.06-8.50). Genotype fre- quency for LPL polymorphism did not differ significantly between UC patients and controls. CONCLUSION: Ser447stop and HindⅢ LPL polymor- phisms may influence age of onset of UC, while HindⅢ and PvuⅡ polymorphisms influence serum triglyceride in UC patients.
