Background The high work intensity and possible subsequently increased susceptibility to occupational hazards of calcium carbide plants may lead to hypertension in workers, but there are few studies on the relationship between occupational hazard exposure and hypertension in workers involving the production process of calcium carbide. Objective To explore the influence of occupational hazards on the incidence of hypertension in calcium carbide plants. Methods Using historical cohort design, the employees of a calcium carbide factory in the western part of Inner Mongolia Autonomous Region were selected as research subjects. According to the pre-determined inclusion and exclusion criteria, the study population comprised an exposure group of 377 employees (including furnace workers, inspection workers, and maintenance workers) exposed to dust, noise & carbon monoxide, and a control group of 388 employees (including central control workers, electricians, and administrative personnel) without above-mentioned exposure. The total sample size was 765 participants. The follow-up period was from April 2011 to October 2022, and the study endpoint was defined as the conclusion of the follow-up period or diagnosed hypertension in annual occupational health examination. Information on general demographic characteristics, living habits, and work status was collected from all study subjects. Cox proportional hazards regression model was used to analyze the association between occupational hazard exposure and the risk of hypertension among the calcium carbide plant employees. Results The average age, mean systolic and diastolic blood pressure, proportion of males, smoking rate, and alcohol consumption rate in the exposure group were higher than those in the control group (P<0.05). Compared to baseline, both systolic and diastolic blood pressure levels increased in the exposure group and the control group at the end of the follow-up (P<0.05). At the end of the follow-up, the average differences between systolic/ diastolic blood pressure and baseline values in the exposure group were higher than those in the control group (P<0.05). During the follow-up period, a total of 223 cases of hypertension occurred, with a total follow-up of

Dementia in traditional Chinese medicine (TCM) mainly presents amnesia and dullness. Alzheimer's disease and vascular dementia belong to the category of dementia in TCM. These progressive neurological diseases have a complex etiology and a long course, and the drugs that can reverse the disease course remain to be developed. Therefore, early intervention plays a vital role in delaying the disease progression. Apathy refers to a lack of motivation that leads to the attenuation or disappearance of goal-directed behaviors, cognitive functions, and emotional responses. Clinical studies have suggested that apathy exists in the early stage of a variety of neurodegenerative diseases, being one of the key symptoms to the early diagnosis of dementia. The severity of apathy is related to the severity of dementia. Therefore, early diagnosis and treatment of apathy are of great significance to the prevention and treatment of dementia. The preclinical research on apathy in dementia is still in its infancy, and the systematic evaluation method has not been prescribed. The clinical diagnosis and treatment are also in the exploratory stage, and the complex pathophysiological mechanisms of apathy and dementia development have not been fully elucidated. This article reviews the research progress of apathy in dementia, the apathetic behaviors of dementia animal models, the behaviors of patients with apathy, and the treatment methods in recent years and summarizes the research status of apathy in dementia. This review aims to provide a theoretical basis for exploring the behavior of apathy in dementia and conducting preclinical research and evaluation of the pathogenesis and to lay a foundation for the treatment of apathy in dementia.

Objective:To evaluate the effects of different exercises on patients with chronic kidney disease based on network Meta-analysis so to provide a basis for medical and nursing staff to develop exercise programs.Methods:Randomized controlled trials on the effects of different exercises on patients with chronic kidney disease were electronically searched in databases such as Web of Science, PubMed, Embase, Cochrane Library, China Biology Medicine disc, WanFang Data, and China National Knowledge Infrastructure. The search period was from January 1, 2000, to March 1, 2023. Two researchers conducted literature screening, data extraction, and literature quality evaluation independently. The data was analyzed by using R software in conjunction with the gemtc package and plotted by using Stata software.Results:A total of 52 articles were included, with a cumulative sample size of 3 127 cases, involving three types of exercise (aerobic, resistance, and combined). The network Meta-analysis showed statistically significant differences between the three exercise methods and routine nursing in delaying renal function progression and improving cardiovascular endurance ( P<0.05). In controlling blood pressure and improving walking ability, the effects of three exercise methods were all superior to routine nursing, and the differences were statistically significant ( P<0.05). The area under the cumulative ranking probability curve showed that aerobic exercise>resistance exercise>combined exercise in terms of delaying renal function progression. In controlling blood pressure, resistance exercise>aerobic exercise>combined exercise. In terms of improving cardiovascular endurance, aerobic exercise>resistance exercise>combined exercise; In terms of improving walking ability, resistance exercise>combined exercise>aerobic exercise. Subgroup analysis showed that ≥ 24 weeks was the optimal intervention period for aerobic exercise. Resistance exercise intervention for ≥ 12 weeks could lower blood pressure, and intervention for ≤12 weeks could improve walking ability. However, when the intervention time was longer than 24 weeks, combined exercise had an excellent effect. Conclusions:Aerobic exercise is an excellent way to delay renal function progression and improve cardiovascular endurance. Resistance exercise is the optimal exercise method for controlling blood pressure and improving walking ability. Medical and nursing staff should choose appropriate types of exercise based on the patient's medical needs.
