Objective To retrospectively a nalyze and think the original papers o f gastrointestinal(GI) imageology for 46 years in Chinese Journal of Radiology(C JR), meeting a huge challenge of Chinese GI imageology in alternation of generat ions. Methods From October 1953 to October 1999, a review of o riginal articles of GI imageology in CJR was conducted. Results Within 46 years of GI imageol ogy evolution, 211 published original articles of CJR included 79 original paper s of radiography and single contrast radiography, 73 original papers of double co ntrast radiography, 21 original papers of interventional radiology, 15 original papers of CT and MR and CR (computed radiograpy), 9 original papers of experim e nt study, and 4 original papers of comprehensive imaging applications. There wer e different dominant imaging applications at different times, radiography and si ngle contrast radiography in fifties and sixties, double contrast radiography an d CT diagnosis in seventies and eighties, and comprehensive applications of CT a nd MR and CR and interventional radiology in nineties. Conclusion In GI imageol ogy for 46 years, double contrast radiography in X-ray diagnosis was the main m e thod of imaging diagnosis, CT and MR and CR diagnosis were important means of re cruit; interventional radiology was an important section of GI imageology in nin eties.

Objective Experimental study of the mechanism in esophageal restenosis after balloon dilation of benign stricture.Methods Esophageal stenosis model of the rats was created by 5ml of 50% NaOH solution burn with double balloon method, and esophageal restenosis (RS) model was developed by esophageal stenosis with dilation of PTCA balloon catheter. Quantitative and quanlitative analysis of esophageal stenosis and RS formation in the rats were observed and recorded by analytic measurements imaging and immunohistologic chemistry respectively. Results Esophageal benign stricture and RS model of 49 rats were developed. Cross section area and perimeter of esophageal mucosa layer, muscule layer and the whole layer had increased in experimental group. Comparing to control group, it had remarkable significance in statistics ( P

Transcatheter bilateral internal lilac arterial embolization therapy (TAE) using CDDP-mierosphere was performed in 19 patients with advanced or recurrent pelvic malignant tumors. The complete response (CR) of turner to the therapy in one patient, partial response (PR) in 12, miner response (MR) in 5, and no changes (NC) in 1, thus the response rate (CR+PR) reached 68% (13/19). The colporrhagia, pain of vulva and lump of buttock were evidently remitted. In the present survived 13 cases, with 1-year for 4 and half-year for 6. The important complications after embolization including mild lower limb paresthesia and hypodynamia in 10 cases, severe lower limb dyscinesia and sensory disturbance in one, pain of buttock in 16, erythema of buttock in two, pain of hip in one and hematochezia in one. The complications have been crucially discussed.

Objective To observed the long-term follow-up of the two types of interventional procedure for achalasia. Methods The study cohort was comprised of 140 patients of achalasia including 70 patients treated under fluoroscopy with pneumatic dilation (group A) and 70 with temporary partially covered metal stent dilation (group B). Results One hundred and forty dilations were performed on the 70 patients of group A with complications of chest pain (n=35), reflux (n=18), and bleeding (n=8); 38 atients of relapsing dysphagia during a 12-month follow-up, and 50 patients out of 60 of recurrent dysphagia during a 36-month follow-up. Seventy partially covered expandable metal stents were temporarily placed in the 70 patients of group B and withdrawn after 3-7 days via gastroscopy with complications of chest pain (n=28), reflux (n=15), and bleeding (n=9); 7 patients out of 70 exhibited dysphagia relapse during a 12-month follow-up, and 9 out of 58 patients exhibited dysphagia relapse during a 36-month follow-up. All the stents were inserted and withdrawn successfully. The follow-up in groups A-B lasted for 12-96 months. Conclusion Temporary partially covered metal stent dilation is one of the best methods of interventional procedure for achalasia in long-term follow-up. (J Intervent Radiol,2005,14:171-174)
