Objective:To explore the latent classes of recurrence risk perception in ischemic stroke patients and their relationship with health behaviors.Methods:Convenience sampling was used to select 312 patients with ischemic stroke from two ClassⅢ Grade A hospitals of Guangzhou from December 2022 to June 2023 as the research subject. Before discharge, the General Information Questionnaire, Recurrence Risk Perception Scale for Patients with Stroke, and Health Behavior Scale for Stroke Patients were used for investigation. One month later, the Health Behavior Scale for Stroke Patients was used for follow-up. Latent class analysis and multiple Logistic regression analysis were used to explore the latent classes of recurrence risk perception and their influencing factors, while multiple linear regression was used to analyze the relationship between latent classes of recurrence risk perception and health behavior at 1-month follow-up.Results:A total of 312 questionnaires were distributed, and 302 valid questionnaires were collected, with an effective response rate of 96.79%. One month later, 261 study subjects completed follow-up. The recurrence risk perception in ischemic stroke patients were divided into four classes of overall low perceived accuracy, light consequence-heavy disease-moderate perceived accuracy, heavy self-care-light diet-upper moderate perceived accuracy, and overall high perceived accuracy. Age, educational level, place of residence and monthly average income were influencing factors for different latent classes ( P<0.05). Compared with patients with overall low perceived accuracy, patients with heavy self-care-light diet-upper moderate perceived accuracy, as well as those with overall high perceived accuracy, showed better health behavior after discharge, with a statistically significant difference ( P<0.05) . Conclusions:Medical and nursing staff should provide targeted nursing interventions based on the common characteristics and individual differences of different classes of patients, helping patients correctly perceive the recurrence risk, improve health behavior, and prevent stroke recurrence.

Objective:To evaluate the clinical efficacy and safety of compound acid combined with Chinese medicinal liniment pourmask in the treatment of pigmentation after acne.Methods:From October 2020 to October 2021, the Department of Dermatology, the First Affiliated Hospital of Anhui College of Traditional Chinese Medicine divided 96 patients with pigmentation after acne inflammation, 34 males, 62 females, aged 18-53 (27.4±7.3) years, into a joint group (compound acid combined with Chinese medicinal liniment pourmask, n=32), compound acid group ( n=32) and Chinese medicinal liniment pourmask group ( n=32). Compound acid was used once every 2 weeks, Chinese medicinal liniment pourmask twice a week, a total of 8 weeks. The clinical efficacy of 2 weeks and 4 weeks after treatment was different from that before treatment ( P<0.05). The pigmentation degree score and the total efficacy of each group were assessed at 2 weeks and 4 weeks after the end of treatment. The occurrence of adverse reactions in each group during the treatment cycle was also recorded. Results:After 2 weeks and 4 weeks of follow-up after the course of treatment, the pigmentation score of the three groups of patients decreased, and the difference was statistically significant ( P<0.05). The total effective rates of the combined group were 68.75% (22/32) and 96.88% (31/32) at 2 and 4 weeks after treatment respectively, both were higher than that of the compound acid group and Chinese medicinal liniment pourmask group ( P<0.05). There was no significant difference in total effective rate between compound acid group and Chinese medicinal liniment pourmask group ( P>0.05). Conclusions:The efficacy of compound acid combined with Chinese medicinal liniment pourmask group in the treatment of pigmentation after acne is remarkable and the safety is good, and therefore it is worth promoting.
