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 To evaluate the relationship between long-term survival rate and protection to marrow and lymphoid tissues in the pelvis with hypoxia radiotherapy for uterine cervical carcinoma. Methods 113 patients, confirmed as having carcinoma of uterine cervix by pathology, were randomly divided by the envelope method into two groups: hypoxia radiotherapy group(HRG,57 patients) and conventional radiotherapy group (CRG,56 patients). HRG was given by sustained inhaling hypoxia gas (oxygen physical volume=0.105) for two minutes before the start of radiotherapy till the end of radiotherapy of each field and then repeated for the other field in the same way. The duration of irradiation to each field was less than five minutes. CRG was given with conventional radiotherapy. The irradiation dose in the midpelvical plane was 20-50Gy depending on the different stages of cervical carcinomatous lesion. The dose of four-divided-field in the parametria was 15-34Gy.The dose at point A of intracavitary therapy was 15-35Gy. Results The decreased value of peripheral blood white cells after treatment was (1.36?1.27)?109/L in HRG and (2.97?1.19)?109/L in CRG(P

Objective To investigate the effect of ear massage on blood pressure and sleep quality of hypertensive patients . Methods Two hundred and ninety-eight elderly hypertensive patients were nursed on the basis of conventional therapy. One hundred and forty-eight patients randomly selected were set as the experiment group, where they were given intervention of ear massage. Another one hundred and fifty patients were set as the control group and treated with conventional interventions. The two groups were compared in terms of blood pressure (systolic and diastolic blood pressure) after nursing interventions and the sleep quality (by Pittsburgh sleep quality index, PSQI). Result After intervention, the diastolic and systolic blood pressure values in the experiment group were both significantly decreased than before intervention (P<0.05) and the quality of sleep was significantly lower than that before intervention (P<0.05). Conclusion Ear massage can be effective in regulating blood pressure in elderly hypertensive patients and improving their quality of sleep.

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)

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
