ABSTRACT

Objective To study the surgical treatment strategy of acute type A aortic dissection involving coronary artery on the basis of Fuwai type and evaluate the clinical efficacy. Methods 50 patients with coronary involvement were retrospec-tively analyzed from April 2014 to August 2016. The treatment mothod was based on Fuwai type,mainly including coronary ar-tery repair(CAR)and coronary artery bypass grafting(CABG). The clinical effect of this surgical strategy in the perioperative and follow-up period was analysed. Results A total of 50 patients were included. Of which,38 patients were treated with CAR, 12 patients CABG,including 3 remedial bypass and 2 prophylactic bypass. All patients were followed up from 4 to 32 months,with an average time of 18. 6 months. In group CABG, 1 patient died of multiple organ failure after surgery,and the other patients had no major adverse cardiovascular events and deaths during perioperative period and follow-up period. Conclu-sion This strategy for the treatment of involved coronary arteries based on the Fuwai type has some guiding significance on the surgical treatment of acute type A aortic dissection.

ABSTRACT

200 papers on nerve root type cervical spondylosis treated with Chinese medicine were retrieved and 38 papers with complete diagnostic criteria and medical statistics were included for study. The results showed acupuncture, massage, and herbal therapy were three common methods and have their own advantage, but systemic, standardized and normative treatment program was lack. In the meantime of treating nerve root type cervical spondylosis, prevention should also be paid attention. The treatment, prevention and exercise on the whole therapeutic idea should be established, which has far-reaching significance.

ABSTRACT

BACKGROUND:Based on the integration of virtual reality technology with acupoints, acupuncture can be expressed three-dimensional y. OBJECTIVE:To explore the structure of points through reconstructing digitalized three-dimensional visualization of Neiguan (PC6) structure based on VOXEL-MAN and Micro-XCT. METHODS:Muscles and other tissues adjacent with Neiguan (PC6) were segmented and merged based on the VOXEL-MAN system combined with the anatomical knowledge of acupoints;nerves and blood vessels were performed with three-dimensional reconstruction;the needle-inserting animation of Neiguan (PC6) was obtained by running script file. Three-dimensional visualization and virtual needle-inserting researches of Neiguan (PC6) were performed. Nature of the acupoints was detected by the Micro-XCT-200 machine additional y. RESULTS AND CONCLUSION:The visualization of the anatomical structure of local Neiguan (PC6) was completed, and the localization and expression of Neiguan (PC6) in the digitized virtual human were realized. The Neiguan (PC6) structure was researched with Micro-XCT-200, and showed there was no new tissue. Local three-dimensional reconstruction of the acupoint structure could help to display the anatomical structure of acupoints and simulate the acupuncture process. It could also help to observe the relationship between the needle body and the surrounding tissues during needle-inserting, which supplying a good basis not only for exploring the security of needle-inserting, but also for improving the clinical effect of acupuncture. The research on the structure of acupoint Neiguan (PC6) by Micro-XCT-200 provides further experimental evidence for the hypothesis of three-dimensional acupoint.
