0.05).Conclusion Trans anal local excision for rectal cancer might only be successfully performed in se lected patients(T_1～T_2N_0M_0,well moderately-differentiated carcinoma). Postoperation adjuant radiation therapy is the main points for T_2 patients to controll local recurrence.

Objective To explore the effect of Jin's three-needle therapy, as an assistant treatment, in improving the intelligence of children with mental retardation (MR).Method Seventy-six MR patients were divided into a control group and an observationgroup, 38 cases in each group.The control group was treated with rehabilitation, while the observation group with JIN's three needle therapy plus the rehabilitation training.Prof. JIN Rui's 10-item observation index was adopted to evaluate the memory ofthe patients before and after the treatment; Gesell Developmental Schedule (GDS) was used to measure the intelligence before and after the treatment. The clinical efficacies in the two groups were statistically analyzed.Result After the treatment, Prof.JIN Rui's 10-item index scores dropped obviously and the GDS scores increased significantly in both groups, while the decrease and increase of scores in the observation group were more significant than those in the control group (P<0.05). The total effective rate was 94.7% in the observation group, significantly higher than 71.1% in the control group (P<0.05).Conclusion As an assistant treatment, JIN's three-needle therapy can help rehabilitation training to improve the intelligence of MR patients.

Objective To survey aesthetics cognition for smiling beauty in young people smile. Methods Smile model was established. The middle incisor width/length ratio, lateral incisor and middle incisor width ratio, difference of lateral incisor and the middle incisor gingival level, gingiva exposure, buccal corridor width and smile line radian were used as variable values to change respectively. A total of 200 young people were selected to evaluate results. The differences in index of ideal value and acceptable range between different dender groups were calculated. Results The ideal value of middle incisor width/length ratio was 0.75, and acceptable range was 0.65-0.85. The ideal value of lateral incisor and middle incisor width ratio was 0.618, and acceptable range was 0.518-0.718. The ideal value of lateral incisor and the middle incisor gingival level difference was-0.5 mm, and the acceptable range was-1-0 mm. The ideal value of gingiva exposure was 0 mm, and the acceptable range was 0-2 mm. The ideal value of buccal corridor was 0.09, and the acceptable range was 0.05-0.21. Coordinate smile was ideal smile line (value=1), and the acceptable range was 0.5-1. There were no statistically significant differences in smile esthetics of six ideal value indicators and acceptable ranges between different gender groups. Conclusion The ideal values and acceptable ranges of six indexes of quantitative criteria can be used for clinical treatment.

Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) enables non-invasive imaging characterization of tissue vascularity with small molecular weight gadolinium chelates. Depending on this technique, tissue blood perfusion, microvessel permeability and extracellular leakage space can be obtained. The basic principles of two dynamic MRI techniques (T2*W and T1W DCE-MRI) and their applications in prostate cancer of DCE-MRI including diagnosis, differential diagnosis, formulation of treatment plan, evaluation of therapeutic reaction, detection of lesion recurrent were reviewed in this article.

Objective To investigate the character and differentiation diagnosis of coronary artery fistula in aged.Methods Clinical symptom, sign and laboratory examination were analyzed in 8 aged patients with coronary artery fistula. Results Myocardial ischemia is the main manifestation of agedness coronary artery fistula, and should be discriminated with coronary artery disease. Conclusion If myocardial ischemia symptom aggravates with age in patient with long-term angina, coronary angiogram is the most dependable method.

Objective To probe into the safety and effectiveness of transcatheter coil embolization for congenital coronary artery fistula. Methods Between May 1999 and December 2002, coil embolization of coronary artery fistula was attempted in 6 patients aged 38 to 70 years (mean, 50.7 years). The fistulae connected the left coronary artery to the pulmonary artery in 2 patients, the right coronary artery to the pulmonary artery in 2, the right coronary artery to the right infra-pulmonary vein in 1, bilateral coronary artery (the left anterior descending artery and right coronary artery) to the pulmonary artery in 1. Results Complete fistula occlusion was achieved in 5 patients (83.3%); one failed to go through the tortuous fistula and gave up coil embolization. There were no operative or late deaths and complications. Follow-up evaluation by physical examination and echocardiography in 5 patients showed no evidence of recurrent or residual coronary artery fistula. Conclusion On the basis of our result, we believe that transcatheter coil embolization of coronary artery fistula is a safe, effective and convenient procedure without a thoracotomy and the use of cardio-pulmonary bypass in some cases.

Objective To study the relation between hyperglycaemia and the prognosis in patients with type 2 diabetes mellitus undergoing coronary revascularization. Methods Study retrospectively 334 type 2 diabetes mellitus patients underwent coronary revascularization, we compare the incidence of hyperglycaemia between patients with good prognosis and patients with bad prognosis undergoing coronary artery bypass graft and percutaneous transluminal coronary angioplasty. We identify by logistic regression analysis the extent of hyperglycaemia as risk factor in the prognosis individually. Results In patients undergoing coronary artery bypass graft and percutaneous transluminal coronary angioplasty, the incidence of hyperglycaemia is higher in patients with bad prognosis than in patients with good prognosis. It is identified by logistic regression analysis that hyperglycaemia deteriorates the prognosis of patients undergoing coronary artery bypass graft (OR=2.033, P=0.008) and patients undergoing percutaneous transluminal coronary angioplasty (OR=2.476, P=0.006). Conclusion To control hyperglycaemia efficiently following coronary revascularization in patients with type 2 diabetes mellitus is mandatory.

Objective To define the CT imaging characteristic of menetrier disease. Methods Four patients with proved Menetrier disease were retrospectively studied by means of CT performed with the water as oral contrast, hypotonic agent and dynamic or spiral CT technique. Results All cases showed that the enlarged rugae were seen projecting into the gastric lumen, but the gastric wall was otherwise normal. CT detected all lesions and made a confirmed diagnosis before pathology biopsy. Conclusion Our primary result revealed that the CT appearance of Menetrier disease was quite characteristic, CT is a very valuable tool for the diagnosis of Menetrier disease.
