OBJECTIVES: This study investigated the seasonal impact of diurnal temperature range (DTR) on hospitalization rates for intracerebral hemorrhage (ICH) in middle-aged and elderly adults. METHODS: We collected data on the DTR and hospitalization records of ≥45-year-old patients with ICH in 2019 in Hunan Province, central China. Time-series analyses were performed using a distributed lag non-linear model. RESULTS: Overall, 54,690 hospitalizations for ICH were recorded. DTR showed a non-linear relationship with ICH hospitalization in both middle-aged and elderly populations (45-59 and ≥60 years, respectively). During spring, a low DTR coupled with persistently low temperatures increased ICH risk in both age groups, while a high DTR was associated with an increased risk in the middle-aged group only (relative risk [RR], 1.24; 95% confidence interval [CI], 1.21 to 1.27). In the summer, a low DTR combined with persistently high temperatures was linked to a higher risk exclusively in the middle-aged group. A high DTR in the autumn was correlated with increased risk in both age groups. In winter, either a low DTR with a continuously low temperature or a high DTR elevated the risk solely in the elderly population (RR, 1.37; 95% CI, 1.00 to 1.69). In the elderly group, the impact of DTR on hospitalization risk manifested within a 5-day period. CONCLUSIONS The impact of DTR on ICH hospitalization risk differed significantly across seasons and between age groups. Elderly individuals demonstrated greater sensitivity to the impact of DTR. Weather forecasting services should emphasize DTR values, and interventions targeting sensitive populations are needed.

Objective:To explore the effect of health management based on constitution identification in perimenopausal women.Methods:From November 2020 to April 2021, 244 perimenopausal women from Doumen Street, Yuecheng District, Shaoxing were selected as the research subject by convenience sampling method, and divided into the control group (121 cases) and the observation group (123 cases) according to their respective communities. The control group adopted routine health management, while the observation group implemented health management based on constitution identification on the basis of routine health management. Three months after intervention, the perimenopausal symptom scores between the two groups were compared. One year after intervention, the number of individuals with biased constitution and quality of life scores between the two groups were compared.Results:Three months after intervention, the scores of hot flashes, sweating, insomnia, dizziness, fatigue, muscle and joint pain, headache, palpitations, and total score of perimenopausal symptom of the observation group were lower than those of the control group, with statistically significant differences ( P<0.05). Three months after intervention, there were no significant differences in scores of paraesthesia, mood swings, depressive suspicion, skin ant sensation, sexual difficulties, urinary tract infection between the observation group and the control group ( P>0.05). One year after intervention, the number of individuals with biased constitution of the observation group was less than that of the control group, and the difference was statistically significant ( P<0.05). One year after intervention, the scores of physical health, mental health, social relationship, and total score of quality of life of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05). One year after intervention, there was no statistically significant difference in the score of the surrounding environment between the observation group and the control group ( P>0.05) . Conclusions:Health management based on constitution identification can improve the perimenopausal symptoms of perimenopausal women, gradually change their biased constitution towards a calm constitution, and improve their quality of life.

Objective: This study aims to explore the effect of practice on the triage and acuity scale in the emergency department of Stomatological Hospital. Methods : 150 emergency patients admitted to the emergency department from April 2016 to July 2016 were randomly selected as the control group before the implementation of graded district diagnosis and treatment, and 150 emergency patients admitted from August 2016 to November 2016 were selected as the observation group after the implementation of graded diagnosis and treatment. The control group was treated with the traditional nursing treatment mode, and the observation group adopted the triage and acuity scale mode. The efficiency of treatment for the patients and the degree of satisfaction of the patients in terms of the nursing work was compared between the two groups (waiting time, checkup time, start treatment time). Results: A comparison of the patients in the observation group and control group showed that the waiting time (min)(25.63 ± 8.75 vs. 35.57 ± 10.60, t = -8.52, P < 0.001), the time of accepting examination (min)(24.80 ± 7.90 vs. 39.23 ± 12.42, t = -12.01, P < 0.001) and the starting time of treatment （min）(28.67 ± 9.37 vs. 40.47 ± 10.86, t = -10.08, P < 0.001) were significantly lower in the observation group than the control group (P < 0.05). The degree of satisfaction with the nursing work for the patients in the observation group (96.67%) was higher than that of the control group (85.33%), and this difference was statistically significant (χ2=17.647, P=0.001). Conclusion The application of a triage and acuity scale in the diagnosis and treatment of stomatological emergency patients according to the severity and urgency of disease can ensure the priority of treatment in critically ill patients, the safe and efficient performance of emergency work, and improvements to the efficiency and quality of emergency medical services.
