Objective: To observe and analyze clinical characteristics of patients with coronary myocardial bridge (CMB) and explore its therapeutic methods. Methods: To retrospectively analyze clinical data of 340 patients undergoing selective coronary angiography (CAG) in our hospital from Jan 2011 to Jan 2013. Results: A total of 33 CMB cases (9.7%) were found in 340 patients undergoing CAG, including 29 cases（87.9%）with isolated myocardial bridge and four patients with coronary atherosclerosis-like changes. There were 31 cases (93.9%) located in left anterior descending branch (LAD), one case (3.03%) in the first diagonal branch (D1) and one case (3.03%) in left circumflex artery (LCX). According to Noble classification of stenosis, 19 cases (57.6%) were class 1, 12 cases (36.4%) were class 2 and two cases (6.06%) were class 3. A total of 16 cases (48.5%) had typical symptoms of angina pectoris, 15 cases (45.5%) had chest tightness and two cases (6.06%) had palpitations. In electrocardiogram and/or dynamic electrocardiogram, ST-T or T wave changes were found in 19 cases (57.6%). All patients received β-receptor blocker and/or non-dyhydropyridine calcium channel blocker, and 29 patients (87.7%) with symptoms improved. Conclusion: Clinical symptoms and manifestations of myocardial bridge is diverse, β-receptor blocker and non-dyhydropyridine calcium channel blocker can relieve most clinical symptoms caused by myocardial bridge.

Objective To investigate the effects of submucosal resection by guidance under esophageal endoscopic ultrasound. Methods 79 cases ofsuspected upper gastrointestinal submucosal tumors were found by endoscopic ultrasonography,transesophageal endoscopic ultra-sound showed lesions under muscularis mucosa,after informed consent,they were underwent endoscopic mucosal resection. Pathological diag-nose of the lesions were found out after resection. Results Compared with pathological results showed that endoscopic ultrasound accurately determine tumor location in the hierarchy;through endoscopic mucosal resection to remove all lesions,5 patients were found bleeding postop-erative,6 patients were found esophageal stricture,the prognosis was good after treatment. Conclusion Endoscopic ultrasonography can accu-rately determine submucosal myoma,it can be used to guide resection of submucosal myoma.

To establish a rat model of diabetes-associated cerebral ischemia due to qi and yin deficiency and blood stasis, and to investigate the effects of Radix Ginseng, Rhizoma Chuanxiong, Rhizoma Polygonati Odorati and Rhizoma Polygonati Sibirici Granule (Shenxiong Yujing Granule), which has the function of strengthening qi, nourishing yin, and activating blood, on proliferation, differentiation and survival of neural cells in rats with diabetes-associated cerebral ischemia.
