As one of the practitioners in the integrated traditional Chinese and western medicine in the period of the Republic of China,Lingnan medical practitioner Zhang Gongwen was a learned person in studying traditional Chinese medicine(TCM),and widely made friends with those people who were interested in TCM,aiming to inherit TCM.Zhang Gongwen was experienced in paracticing TCM and was quite accomplished.He popularized and developed TCM by setting up the New Chinese Medicine Training Center,renewing the Guangdong Meixian School of Traditional Chinese Medicine,establishing journals,and running the sanatoriums.He was a good physician with years of clinical experience and cared for the patients,reaching the medical goal of serving people's health.He spread medical knowledge and cultivated medical talents by compiling and publishing a number of TCM textbooks and setting up correspondence course.He was a promising figure who actively explored the integration of traditional Chinese and western medicine during the period of the Republic of China,by examing TCM and advocating science,trying to integrate the essence of western medicine into TCM,thus to make TCM be more specific and scientific.Zhang Gongwen contributed all his efforts to the continuation and development of TCM in Lingnan during the hard times of TCM,and was a precious medical talent at that time.

ObjectiveTo explore the characteristics of balance and cortical activation in older adults when performing cognition-balance dual tasks. MethodsFrom January to April, 2023, 20 healthy older adults were non-targeted recruited. They completed six tasks of close eyes & fixed platform (CF), close eyes & fixed platform & cognitive task (CFc), open eyes & sway-referenced platform (OS), open eyes & sway-referenced platform & cognitive task (OSc), close eyes & sway-referenced platform (CS), and close eyes & sway-referenced platform & cognitive task (CSc) on the Balance SD, wearing functional near-infrared spectroscopy caps. The overal stability index (OSI) was measured with Balance SD. The premotor cortex (PMC), sensorimotor cortex (SMC) and prefrontal cortex (PFC) were as regions of interest (ROIs), and the β values were calculated. ResultsThe OSI was more as CFc than as CF (Z = -2.014, P < 0.05), and was less as CSc than as CS (Z = -2.063, P < 0.05). The β values of bilateral ROIs were all more as CFc than as CF (|Z| > 2.464, |t| > 3.733, P < 0.05), and as OSc than as OS (|t| > 2.308, P < 0.05); the β value of the right SMC was more as CSc than as CS (t = -2.912, P < 0.05). The number of correct counts was less as CSc than as CFc and OSc (|Z| > 3.643, P < 0.001). ConclusionBalance has been impaired under dual tasks for older adults, while activation of cerebral cortex increases. However, for more difficult balance task, older adults would preferentially maintain postural balance under dual tasks, while cognitive performance decreases, which may be the results from no more activation of cerebral cortex under dual tasks.
