[Consistent presentation of medical images based on CPI integration profile].

Because of different display parameters and other factors, digital medical images present different display states in different section offices of a hospital. Based on CPI integration profile of IHE, this paper implements the consistent presentation of medical images, and it is helpful for doctors to carry out medical treatments of teamwork.

[A positioning error measurement method in radiotherapy based on 3D visualization].

The positioning error in radiotherapy is one of the most important factors that influence the location precision of the tumor. Based on the CT-on-rails technology, this paper describes the research on measuring the positioning error in radiotherapy by comparing the planning CT images with the treatment CT images using 3-dimension (3D) methods. It can help doctors to measure positioning errors more accurately than 2D methods.

Loss of heterozygosity in multistage carcinogenesis of esophageal carcinoma at high-incidence area in Henan Province, China.

Aim: Microsatellites are the repeated DNA sequences scattered widely within the genomes and closely linked with many important genes. This study was designed to characterize the changes of microsatellite DNA loss of heterozygosity (LOH) in esophageal carcinogenesis.

Methods: Allelic deletions in 32 cases of matched precancerous, cancerous and normal tissues were examined by syringe microdissection under an anatomic microscope and microsatellite polymorphism analysis using 15 polymorphic markers on chromosomes 3p, 5q, 6p, 9p, 13q, 17p, 17q and 18q.

[Comparative genomic hybridization of esophageal squamous cell carcinoma and gastric cardia adenocarcinoma in high-incidence region of esophageal carcinoma, Linzhou Henan].

Objective: To characterize the profiles of chromosome imbalance in esophageal squamous cell carcinoma (SCC) and gastric cardia adenocarcinoma (GCA) from the high incidence area in Henan.

Methods: Chromosomal aberrations of 37 samples of SCC and 30 GCA were analyzed by comparative genomic hybridization comparative genomic hybridization (CGH).

Results: It was found that the most frequently detected gains were on chromosome arm 8q (78%), and followed by 3q, 5p, 6q and 7p.

Proteomic analysis of blood level of proteins before and after operation in patients with esophageal squamous cell carcinoma at high-incidence area in Henan Province.

Aim: To characterize the protein files in blood from same patients with esophageal squamous cell carcinoma (ESCC) before and after operation at the high-incidence area for ESCC in Henan Province, China.

Methods: Two-dimensional electrophoresis, silver staining and ImageMaster 2-DE analysis software were applied to the determination of protein files in the blood obtained from normal controls and ESCC patients before and after operation.

Results: A total of 655, 662 and 677 protein spots were identified, respectively, from the normal controls and ESCC patients before and after operation.
