Objective: To evaluate the effect of chewing sugar-free gum on gastrointestinal function recovery after cesarean section. Methods: Randomized controlled trials comparing the use of chewing gum in postoperative recovery with a control group were retrieved from the databases including Pubmed, Cochrane Library, Science Direct, Web of Science, CBM, CNKI, Wanfang and VIP, et al. After screening literatures, evaluating the quality of studies, extracting data, the RevMan5.3 software was used for data analysis. Results: A total of 13 RCTs including 2233 patients were analyzed in the study. The results showed that chewing gum after cesarean delivery can effectively shorten the recovery time of bowel sounds, passage of flatus and first defecation (all P < 0.05). Conclusion: Chewing sugar-free gum after cesarean section can promote the early recovery of gastrointestinal function, but the side effects of chewing gum are still unclear, which needs more clinical, large sample and high-quality studies to further verify.

Traditional Chinese Medicine and Traditional Chinese Culture" is a general education elective course offered by Yangtze University. This paper introduces the construction of the course from six aspects: course objectives, course construction, teaching design, course assessment and evaluation, course characteristics and innovation, and continued construction plan, which can provide some reference for the construction of similar courses.

Alzheimer's disease (AD) is a progressive neurodegenerative disease, is one of the leading causes of death in the aging population, and has become a serious public problem endangering the physical and mental health of the elderly. The disease not only affects the health of the elderly and the quality of life in their later years, but also brings heavy financial and emotional burden to the family and society. The specific mechanism of AD is still unclear, and the current treatments focus on improving mental function and slowing down memory loss. The early diagnosis of AD is difficult and there is no cure for it, so the early prevention is particularly important. This review will introduce the major treatment, potential risk factors and summarize the relevant research about early preventions of AD, such as regular physical sports, reasonable nutritional diet, certain social activities and so on, and expect to provide a new direction for the improvement of AD.

Background: Frailty is a geriatric syndrome, and a common negative consequence of aging, which shares some obvious characteristics as cognitive impairment. Preventing and relieving frailty may reduce the possibility of developing cognitive impairment. Objective: This study aimed to investigate frailty prevalence and its correlation with cognitive function in elderly surgical inpatients. Methods: We enrolled a random sample of elderly surgical inpatients from Jingzhou from June 2020 to August 2020. We used a self-made registration sheet to collect their demographic data (gender, age, nationality, educational level and monthly income), and used the FRAIL Scale to assess the prevalence of frailty, and used the Mini-Mental State Examination (MMSE) to assess cognitive function. We used multiple linear regression analysis to explore the correlation between frailty level and demographic data, then Pearson correlation analysis was performed to analyze the correlation between frailty and cognitive function. Results: In the 143 elderly surgical inpatients, prevalence of frail was seen in 29 (20.3%), and pre-frail state was found in 64 (44.8%). Only 50 (34.9%) were in healthy state. Cognitive impairment was seen in 28 (19.5%). Pearson correlation analysis showed that the frail scoring was correlated with cognitive function in elderly surgical inpatients (r = −0.378, P < 0.05). Conclusion: The prevalence of frailty is high in elderly surgical inpatients, which is closely related to age and gender. Elderly surgical inpatients have high cognitive impairment, and frailty appears strongly associated with cognitive status. The findings suggest that attention should be paid to the frailty and cognitive function in the elderly surgical inpatients by provision of effective interventions.
