A new dibenzocyclooctadiene lignan, renchangianin E (1) was isolated from the stems of Kadsura renchangiana. Its structure and stereochemistry were elucidated by spectroscopic methods, including 2D-NMR techniques.

Against the backdrop of global climate change and environmental degradation,green development has become a key issue in the healthcare industry.This paper takes the Workers'Hospital of Liuzhou as a case study to explore the applica-tion and challenges of artificial intelligence(AI)technology in promoting the development of green hospitals.The paper analyzes in detail the application of AI technology in key areas such as intelligent navigation and triage,smart logistics systems,medical imaging expert systems,image cloud films,and electronic health cards.It demonstrates the significant effects of AI technology in improving medical service efficiency,enhancing patient experience,and optimizing the allocation of medical resources.At the same time,the paper also points out the challenges faced by AI technology in the application process in the medical field,inclu-ding issues of data security and privacy protection.Through case analysis,this paper aims to provide reference and inspiration for other medical institutions,as well as to encourage further research and exploration of the problems and challenges faced by AI technology in the healthcare field.

BACKGROUNDLocally advanced lung cancer includes IIIA and IIIB lung cancer that tumors are localized within the chest and with no clinic and pathologic distal metastasis. In this study the results of extended resection of a portion of heart or great vessels with cardiopulmonary bypass was summarized in the treatment of locally advanced lung cancer.

METHODSLobectomy or pneumonectomy combined with extended partial excision of the heart or great vessels were carried out in 10 patients with locally advanced lung cancer. The operations included aortic resection and reconstruction with left heart bypass in 2 cases, extended resection of left atrium with normal cardiopulmonary bypass in 5 cases, and resection and reconstruction of superior vena cava in 3 cases respectively.

RESULTSThe patients had no operative complication except for one haemothorax, which was controlled by re-exploration. One patient died of brain metastasis 6 months after operation and another one died of multiple metastasis 26 months after operation. The others were alive.

CONCLUSIONSCPB is a safe and effective anesthetic procedure during extended resection of locally advanced lung cancer although it is controversial for aggravating operative trauma, complex technique and higher cost.
