Objective To investigate the mediating effect of psychological flexibility on the relationship between pain self-efficacy and kinesiophobia in patients with lumbar disc herniation(LDH),so as to provide references for relief from kinesiophobia of the patients.Methods Convenience sampling was used to select 256 patients with LDH as the research subjects from the Outpatient Department of Spinal Orthopaedics of a Grade IIIA hospital in Guangdong Province between May and December 2023.The subjects were surveyed with a general information questionnaire,the kinesiophobia assessment scale,psychological flexibility inventory for pain patients,and chronic pain self-efficacy scale.The mediation effect of psychological flexibility on pain self-efficacy and kinesiophobia was analysed using SPSS 26.0 and the PROCESS 3.5 macro.Results The scores for kinesiophobia,psychological flexibility and pain self-efficacy among the LDH patients were 31.66±4.73,55.26±11.06 and 68.14±17.48,respectively.Kinesiophobia was positively correlated with the psychological flexibility(r=0.545,P<0.001)and negatively correlated with the pain self-efficacy(r=-0.599,P<0.001).The psychological flexibility was negatively correlated with the pain self-efficacy(r=-0.510,P<0.001).Psychological flexibility partially mediated the relationship between pain self-efficacy and kinesiophobia,with a mediating effect of-0.045,accounting for 27.78%of the total effect.Conclusion The patients who have LDH and under conservative treatment exhibit a high level of kinesiophobia and with a moderate levels of pain self-efficacy and psychological flexibility.The medical staff can improve the self-efficacy and psychological flexibility of patients,so as to reduce kinesiophobia level and its incidence.

Objective To investigate the types of latent profiles and influencing factors of knowledge,attitudes and practice(KAP)in curriculum-based ideological and political education in undergraduate nursing students and to provide evidence for design of ideological and political courses tailored to different types of nursing undergraduates.Methods A convenience sampling method was used to recruit 671 undergraduate nursing students from our school between March and July 2024.Data were collected using a general data survey form,a KAP questionnaire on nursing curriculum-based ideological and political education,a professional identity survey for nursing undergraduates,and the Jefferson empathy scale nursing student edition(JSPE-NS).Latent profile analysis(LPA)was conducted using 22 items of the KAP questionnaire as observed variables,and a logistic regression analysis was used to assess the influencing factors of different KAP latent profiles in ideological and political education.Results A total of 663 nursing undergraduate students completed the survey.They spread in three latent groups:a mediocre group(172/663,25.9%),a competent group(378/663,57.0%),and an exceptional group(113/663,17.1%).From a single-child family,grade point average(GPA),professional identity and empathy were identified as the factors that influenced KAP latent profiles in curriculum based ideological and political education among the undergraduate nursing students(all P<0.05).Conclusion There exists a heterogeneity in KAP in curriculum based ideological and political education among the undergraduate nursing students.Nursing educators should develop targeted enhancement measures according to the characteristics of latent profile groups therefore to facilitate the comprehensive development of the undergraduate nursing students.

Objective:To investigate the impact of olanzapine and risperidone on the cognitive function, sensory gating function and clinical symptoms of patients with first-episode schizophrenia(FES).Additionally, to analyze the correlation between sensory gating inhibitory deficits and cognitive impairment in FES patients.Methods:A total of 71 FES patients were selected in the Third People's Hospital of Zhongshan City from March 2023 to March 2024, and 60 healthy controls were recruited during the same period.The FES patients were divided into olanzapine group and risperidone group by random number table.Olanzapine group was treated with variable doses of olanzapine(10-20 mg/d), and risperidone group was treated with variable doses of risperidone(3-6 mg/d).The MATRICS consensus cognitive battery(MCCB) was used to evaluate the cognitive function of the patients, P50 index was measured by auditory paired condition-stimulus paradigm, and the efficacy was evaluated by positive and negative syndrome scale(PANSS) score reduction rate before and after 6 weeks of treatment.Healthy controls were assessed cognitive function only once with P50.SPSS 25.0 software was used for data processing. Perform statistical analysis using paired sample t-test, Wilcoxon signed rank test, independent sample t-test, Mann Whitney U test, χ2 test and generalized linear model. Results:Before treatment, the S2 amplitude of FES (1.74 (0.91, 2.79) μV) was higher than that of healthy controls (1.70 (1.04, 2.71) μV) (Wald χ2=4.483, P=0.034), the S2/S1 ratio of FES (0.58 (0.43, 0.78)) was higher than that of healthy controls (0.41 (0.31, 0.57)) (Wald χ2=10.909, P=0.001), and the difference of FES amplitude of S1-S2 was (1.22 (0.43, 1.92) μV) was lower than that of healthy controls (2.23 (1.54, 3.07) μV) (Wald χ2=17.679, P<0.001). There was no significant difference in PANSS, MCCB and P50 between olanzapine group and risperidone group before treatment (all P>0.05). After treatment, there was no significant difference in response rate between the two groups ( χ2=0.059, P=0.808), the PANSS scores were lower than those before treatment, the MCCB test results were higher than those before treatment (both P<0.05), and the P50 results were not statistically significant different compared with those before treatment (both P>0.05). The generalized linear model showed that the S1, S2 amplitude of the P50 had positive impact on the connection test score in the MCCB test ( β=0.466, P=0.020; β=0.879, P=0.009), other indicators were not found to have an impact on the test scores of the MCCB test (all P>0.05). Conclusion:Olanzapine and risperidone can significantly improve the cognitive function of FES, but the improvement of sensory gating deficits is limited. The pathogenic mechanism of sensory gating inhibitory deficits in FES may be different from that of cognitive dysfunction.

Objective:To investigate the prevalence and influencing factors of kinesiophobia in chronic pain patients undergoing conservative treatment for lumbar disc herniation (LDH), providing reference and basis for reducing the occurrence of kinesiophobia in this patient population.Methods:A cross-sectional study was conducted from May 2023 to January 2024. A convenience sample of chronic pain patients undergoing conservative treatment for LDH in Guangdong Second Provincial General Hospital was selected as the study population. Data were collected by the general information questionnaire, Numerical Rating Scale, Tampa Scale of Kinesiophobia-11, Psychological Inflexibility in Pain Scale, and Chronic Pain Self-efficacy Scale. A random forest model was constructed to rank variable importance, and binary Logistic regression was used to analyze the influencing factors of kinesiophobia.Results:The effective response rate of the questionnaire was 96.8% (270/279). Among 270 patients, there were 139 males and 131 females, 92 patients aged 18-40 years, 132 patients aged 41-60 years, and 46 patients aged >60 years old. The total kinesiophobia score for chronic pain patients undergoing conservative treatment for LDH was (31.00 ± 5.09) points, with a kinesiophobia prevalence of 79.6% (215/270). The random forest algorithm identified eight influencing factors: pain self-efficacy, psychological flexibility, physical exercise after low back pain onset, duration of pain, pain status, understanding of LDH, marital status, and pain intensity. Binary Logistic regression analysis showed that physical exercise after low back pain onset ( OR=0.583, 95% CI 0.344-0.986), pain status ( OR=0.424, 95% CI 0.206-0.873), psychological flexibility ( OR=1.102, 95% CI 1.052-1.155), pain self-efficacy ( OR=0.923, 95% CI 0.895-0.953) were significant influencing factors of kinesiophobia in chronic pain patients undergoing conservative treatment for LDH (all P<0.05). Conclusions:The prevalence of kinesiophobia is high among chronic pain patients undergoing conservative treatment for LDH. Physical exercise after low back pain onset, pain status, psychological flexibility, and pain self-efficacy are significant influencing factors. Healthcare professionals should pay increased attention to kinesiophobia in chronic pain patients undergoing conservative treatment for LDH and implement targeted early interventions to reduce its occurrence.
