Objective:To explore the mediating effect of psychological resilience on the aggressive coping confidence and post-traumatic growth of psychiatric nurses.Methods:From July to September 2022, convenience sampling was used to select 1 200 psychiatric nurses from 5 psychiatric hospitals in Guangdong Province who had experienced workplace violence incidents as the research subject. The General Information Questionnaire, Confidence in Coping with Patient Aggression Instrument (CCPAI) , Connor-Davidson Resilience Scale (CD-RISC) , and Post-Traumatic Growth Inventory (PTGI) were used to investigate psychiatric nurses. Pearson correlation analysis was used to explore the association between nurses' aggressive coping confidence, psychological resilience and post-traumatic growth. Multiple linear regression was used to analyze the influencing factors of post-traumatic growth, and the Process plug-in was used to conduct non parametric repeated measurement to test the mediating effect. A total of 1 200 questionnaires were distributed, with 135 invalid questionnaires excluded and an effective recovery rate of 88.75%.Results:1 065 psychiatric nurses scored (35.41±7.56) on their aggressive coping confidence, (65.55±16.73) on their psychological resilience, and (65.32±16.60) on their post-traumatic growth. The total score of post-traumatic growth was positively correlated with the aggressive coping confidence ( r=0.371, P<0.01) , and positively correlated with psychological resilience ( r=0.663, P<0.01) . Multiple linear regression analysis showed that aggressive coping confidence, toughness dimension, self-improvement dimension, marital status, and positional title were the main influencing factors for the post-traumatic growth of psychiatric nurses ( P<0.05) . Psychological resilience played a part of the mediating effect (36.69% of the total effect) in aggressive coping confidence and post-traumatic growth. Conclusions:The post-traumatic growth, aggressive coping confidence and psychological resilience of psychiatric nurses are at a medium level. The post-traumatic growth, aggression coping confidence and psychological resilience of psychiatric nurses who have experienced workplace violence are closely related. Psychological resilience has a mediating effect between aggression coping confidence and post-traumatic growth. The post-traumatic growth of psychiatric nurses can be improved by intervening their aggressive coping confidence and psychological resilience.

Objective:To compare the effect and clinical significance of unilateral and bilateral percutaneous kyphoplasty (PKP) combined with hyperextension reduction in the treatment of fresh osteoporotic vertebral compression fracture (OVCF).Methods:The clinical data of OVCF patients treated in Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical University from January to December 2018 were retrospectively analyzed.A total of 62 patients were included.According to the surgical approach, 62 patients were divided into unilateral puncture approach group and bilateral puncture approach group, with 31 cases in each group.The patients in the unilateral puncture group were treated with limb hyperextension reduction combined with unilateral PKP.In the bilateral puncture approach group, limb hyperextension reduction combined with bilateral PKP was used.The changes of visual analogue pain scale (VAS), Oswestry disability index (ODI), vertebral anterior height, vertebral midline height and Cobb angle were observed and compared before operation, 1 day and 2 weeks after operation.At the same time, the operation time, intraoperative fluoroscopy times, intraoperative bone cement injection and adverse reactions were compared between the two groups.Results:The VAS scores of patients in the unilateral puncture approach group before operation, 1 day and 2 weeks after operation were (8.10±0.17), (2.20±0.26) and (1.90±0.39), respectively.The scores of bilateral puncture approach group were (8.10±0.13), (2.30±0.26) and (2.00±0.30), respectively.The results of repeated measurement ANOVA showed that F intra-group=13 790.444, P<0.001, F inter-group=1.951, P=0.168, F interaction=0.735, P=0.481.There were significant differences in VAS scores between the two groups 1 day and 2 weeks after operation (all P<0.05). There was significant difference in VAS score between the two groups 1 day after operation and 2 weeks after operation (all P<0.05). The ODI scores of patients in the unilateral puncture group before operation, 1 day and 2 weeks after operation were (40.30±5.30), (23.20±3.40), (22.30±4.49) points respectively, and those in the bilateral puncture group were (41.00±4.49), (21.90±2.48), (20.70±5.70) points, respectively.The results of repeated measurement ANOVA showed that F intra-group=339.046, P<0.001, F inter-group=1.385, P=0.244, F interaction=1.083, P=0.342.There were significant differences in ODI scores between the two groups 1 day and 2 weeks after operation (all P<0.05). There was significant difference in ODI score between the two groups 1 day after operation and 2 weeks after operation (all P<0.05). The anterior height of vertebral body in unilateral puncture group was (18.26±2.40), (21.97±1.17), (22.03±1.35) mm before operation, 1 day and 2 weeks after operation, and that in bilateral puncture group was (18.94±1.80), (22.06±2.79), (20.29±1.19) mm.The results of repeated measurement ANOVA showed that F intra-group=51.228, P<0.001, F inter-group=1.594, P=0.212, F interaction=6.452, P=0.002.There were significant differences in the anterior vertebral height between the two groups 1 day and 2 weeks after operation (all P<0.05). The height of vertebral midline in the unilateral puncture group was (17.97±2.14), (26.13±1.43), (26.00±1.79) mm before operation, 1 day and 2 weeks after operation, and in the bilateral puncture group was (18.84±1.77), (24.74±1.77), (24.68±2.06) mm.The results of repeated measurement ANOVA showed that F intra-group=358.837, P<0.001, F inter-group=3.850, P=0.054, F interaction=9.117, P<0.001.There were significant differences in the height of vertebral midline between the two groups 1 day and 2 weeks after operation (all P<0.05). The Cobb angles in the unilateral puncture group were (21.74±2.11)°, (11.77±1.91)° and (10.94±1.12)° before operation, 1 day and 2 weeks after operation, respectively, and in the bilateral puncture group were (22.13±2.50)° and (12.0±2.38)° and (11.71±1.37°, respectively.The results of repeated measurement ANOVA showed that F intra-group=674.732, P<0.001, F inter-group=1.975, P=0.165, F interaction=0.376, P=0.688.There were significant differences in Cobb angle between the two groups 1 day and 2 weeks after operation (all P<0.05). There were significant differences in operation time ((52.0±3.8) min and (67.0±6.7) min), intraoperative fluoroscopy times ((15.0±5.8) times and (32.0±6.1) times), and bone cement injection volume ((4.6±0.3) mL and (5.0±0.1) mL) between unilateral puncture approach group and bilateral puncture approach group (all P<0.001). Conclusion:Unilateral and bilateral PKP combined with hyperextension reduction can alleviate the pain of OVCF, restore the lost vertebral height and correct kyphosis.The unilateral puncture approach PKP combined with hyperextension reduction has the advantages of shorter operation time, concise operation process, fewer times of intraoperative fluoroscopy and less use of bone cement.

This paper introduces the concept, basic theory and interventions of reminiscence therapy, summarizes the application status of reminiscence therapy in elderly patients with mental disorders and puts forward the prospect, so as to provide reference for research in China.

Idiopathic normal pressure hydrocephalus (iNPH) is a significant cause of the severe cognitive decline in the elderly population. There is no cure for iNPH, but cognitive symptoms can be partially alleviated through cerebrospinal fluid (CSF) diversion. In the early stages of iNPH, cognitive deficits occur primarily in the executive functions and working memory supported by frontostriatal circuits. As the disease progresses, cognition declines continuously and globally, leading to poor quality of life and daily functioning. In this review, we present recent advances in understanding the neurobiological mechanisms of cognitive impairment in iNPH, focusing on (1) abnormal CSF dynamics, (2) dysfunction of frontostriatal and entorhinal-hippocampal circuits and the default mode network, (3) abnormal neuromodulation, and (4) the presence of amyloid-β and tau pathologies.

BackgroundThe existing tools in China for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint do not sufficiently consider the specialty in psychiatric practice， and the scale items are somewhat cumbersome to use， which together restrict their further promotion and application. Accordingly， there is an urgent need for developing a more scientific assessment tool. ObjectiveTo construct a scale for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint and to verify its reliability and validity， so as to provide a generic tool for the assessment. MethodsBased on the theoretical framework of the knowledge-attitude-practice model， the preliminary scale was formed through systematic literature review， qualitative interview and Delphi method. From July to December 2021， a stratified sampling was utilized to select 729 psychiatric nurses from tertiary， secondary and primary （including unclassified medical institutions and grassroots hospitals） psychiatric hospitals in Guangdong Province. The formal scale was developed through item analysis， exploratory factor analysis and confirmatory factor analysis. The validity of the scale was evaluated by content validity and structure validity， and the reliability was verified by procedures including Cronbach's α coefficient， test-retest reliability， and split-half reliability. ResultsA total of 12 items of three dimensions （knowledge， attitude， practice） were included in the scale for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint. The scale-level content validity index （S-CVI） was 0.941， and the item-level content validity index （I-CVI） ranged from 0.812 to 1.000. Exploratory factor analysis extracted three common factors， and the cumulative variance contribution rate was 62.948%. The confirmatory factor yielded adequate fit. Cronbach's α coefficient was found to be 0.887 for the scale， 0.819 for knowledge dimension， 0.842 for attitude dimension， and 0.831 for practice dimension. The split-half reliability and test-retest reliability for the scale were 0.712 and 0.922， respectively. ConclusionThe scale shows satisfactory reliability and validity， which can be used to assess psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint. ［Funded by Guangdong Clinical Teaching Base Teaching Reform Research Project （number， 2021JD119）］
