Objective:To standardize the management of auditory hallucination symptoms in inpatients with mental illness and develop an expert consensus on the management of auditory hallucinations in hospitalized psychiatric patients.Methods:From March 2023 to July 2023, the Mental Health Committee of the Chinese Nursing Association focused on the key issues in the management of auditory hallucinations symptoms in inpatients with mental illness, based on clinical practice, using literature analysis combined with the work experience of mental health experts, and formed the first draft of the expert consensus on the management of auditory hallucinations in inpatients with mental illness (hereinafter referred to as the consensus). Through 3 rounds of expert consultation and 3 rounds of expert demonstration meeting, the draft was adjusted, revised, and improved.Results:37 experts were included in the Delphi expert consultation, 1 male and 36 females with 39-67(51.48 ± 6.61) years old. The positive coefficients of experts in 3 rounds of Delphi expert consultations were all 100%, and the degrees of expert authority were 0.924, 0.938 and 0.949, respectively. The average importance value of each item was higher than 4.00, the variation coefficient of each item was less than 0.25. The Kendall harmony coefficient of the experts were 0.179, 0.195 and 0.198, respectively (all P<0.05). There were 15, 12, 12 experts in the first, seeond, third rounds of expert demonstration meeting. Finally, a consensus was reached on the recommendation of 4 parts, included auditory hallucination assessment, management format, symptom management implementation, and precautions. Conclusions:The consensus covers all parts of the management of auditory hallucination symptoms in hospitalized patients with mental disorders, which is practical and scientific. It is helpful to guide mental health professionals to standardize the management of auditory hallucination symptoms, improve the quality of nursing and ensure the safety of patients.

Objective:To analyze the relationship between self-disclosure, self-efficacy and medical coping modes in adolescent depression, and explore the mediating effect of self-efficacy between self-disclosure and medical coping modes.Methods:Using the convenience sampling method, a total of 403 adolescents with depression in a tertiary psychiatric hospital in Beijing were recruited from March 2020 to March 2021. The data of general information questionnaire, distress disclosure index scale, medical coping modes questionnaire and general self-efficacy scale were collected.SPSS 26.0 software was used to analyze the correlation between self-disclosure, self-efficacy and medical coping modes of adolescent patients with depression, and Stata 13.1 software was used to analyze the mediating effect of self-efficacy between self-disclosure and medical coping modes.Results:The scores of dimension of the medical coping modes of adolescent depression patients were(16.90±3.84) for facing, (16.34±2.88) for yielding, (12.48±4.31) for avoiding, (30.47±9.91) for self-disclosure and (19.63±6.54) for self-efficacy, respectively. Self-disclosure and self-efficacy were positively correlated with facing of medical coping modes ( r=0.301, 0.327, both P<0.01), and negatively correlated with yielding of medical coping modes ( r=-0.465, -0.487, both P<0.01). Self-disclosure was negatively correlated with avoidance of medical coping modes ( r=-0.118, P=0.018). The direct effect of self-efficacy on medical coping modes was 0.103, and the total effect was 0.365, and the mediating effect accounted for 28.22%. Conclusion:Self-efficacy partially mediates between self-disclosure and medical coping modes in adolescents with depression.

Objective : To establish a mouse model of acute pseudomembranous stomatitis and to observe the effect of photoactivated disinfection (PAD) on the removal of Candida albicans in vivo, and initially explore the feasibility of this technology in the treatment of acute pseudomembranous stomatitis. Methods: Six-week-old male ICR mice were selected and immunized with 1 × 107CFU/mL Candida albicans solution on the backs of the tongues of immunosuppressed mice. Thirty model mice with acute pseudomembranous stomatitis were successfully established and randomly divided into a control group and a photoactivated disinfection group, with 15 mice in each group. Mice in the photoactivated disinfection group were coated with 1 mg/mL toluidine blue solution on the back of the tongue, incubated for 1 min and irradiated with 750 mW LED red light for 1 min. Immediately after treatment, the tongue fungal load was measured in the photoactivated disinfection group and the control group. Tongue fungal load was measured again 48 h later, and tongue histopathological examination was performed in both groups. Results : Forty-eight hours after PAD treatment, the white pseudomembrane on the back of the tongue in the photoactivated group was significantly less than the control group. The fungal load on the dorsum of the tongue in the treatment group was significantly lower than the control group immediately and 48 h after treatment for PAD, and the difference was statistically significant (P<0.05). Forty-eight hours after PAD treatment, HE staining showed that the epithelial structure of the PAD group was more regular than the control group, and no microabscesses were observed. PAS staining showed that the number of mycelia in the PAD group was significantly less than the control group. Mycelia occasionally invaded the keratinized layer but did not penetrate into the upper cortex. Conclusion PAD significantly removed Candida albicans from the tongues of mice with acute pseudomembranous Candida stomatitis.

Objective:To explore the influence of mindfulness on perceived stress in psychiatric nurses and the mediating effect of resilience.Methods:A total of 427 psychiatric nurses from a psychiatric hospital in Beijing were selected.Five-facet mindfulness questionnaire(FFMQ), Chinese-version perceived stress scale (CPSS) and Connor-Davidson resilience scale (CD-RISC) were used in this survey.Pearson correlation analysis and multiple stepwise regression analysis were performed using SPSS 24.0.And mediating effect was performed using AMOS 24.0.Results:The total score of psychiatric nurses' perceived stress was (37.89±7.16). Among all psychiatric nurses, 66.74% were under high pressure and 20.84% were under great pressure.The perceived stress was negatively correlated with mindfulness(123.69±10.82, r=-0.65, P<0.01) and resilience(85.40±17.87, r=-0.67, P<0.01), and mindfulness was positively correlated with resilience ( r=0.50, P<0.01). The direct effect of mindfulness on perceived stress was -0.15, the indirect effect was -0.34, and the total effect was -0.49. Conclusion:Resilience plays a partial mediating role between mindfulness and perceived stress psychiatric nurses.

To understand the survival stress of community-dwelling people with mental disorder. Fifteen cases were selected by purposive sampling and received semi-structured individualized interviews.The data were analyzed by Colaizzi framework and themes were extracted. Four themes were extracted:physiological stress due to psychiatric symptoms and side effects of drugs;psychological stress due to the outcome of mental illness and to conflict of roles in daily life;social and environmental stress such as social discrimination,lack of job opportunities,and difficulty in obtaining social welfare resources;and interpersonal stress caused by discrimination and deteriorating family relations. Community-dwelling people with mental illness have a higher level survival stress after returning to their families and society,with the stressors including symptoms of illness,social discrimination,and interpersonal relationship.Eliminating self-discrimination of the patients,improving social support and social welfare system,and increasing individualized community mental rehabilitation activities may reduce the survival stress of these patients and promote their rehabilitation.

Objective:To prepare a drug release system of drug-loaded cross-linked decellularized corneal stromal lenticules and evaluate its drug release characteristics in vitro. Methods:Lenticules were obtained during femtosecond laser-assisted small incision lenticule extraction (SMILE) surgery in Chongqing Aier Ophthalmology Hospital.Decellularized corneal stromal lenticules were prepared using high concentration sodium chloride (NaCl) combining nuclease.The decellularized corneal stromal lenticules were randomly divided into normal group, 0.5% levofloxacin group, 3% levofloxacin group and 5% levofloxacin group, with 4 lenticules in each group.The lenticules did not receive any treatment in the normal group, and drug-loading those were soaked in different doses of levofloxacin solution for three hours according to grouping.In the crosslinking test, 12 decellularized corneal stromal lenticules were randomly divided into non-crosslinking group, 0.01 mmol 1-(3-dimethylamino) propylimine (EDC) group, 0.05 mmol EDC group and 0.25 mmol EDC group.The lenticules for cross-linking were soaked in different contents of mixed solution of EDC with N-hydroxysuccinyl (NHS) for four hours respectively according to grouping, and then in 3% levofloxacin solution for three hours.Only 3% levofloxacin solution soaking was carried in the non-crosslinking group.High performance liquid chromatography (HPLC) was employed to detect the drug release concentration of the lenticules, and spectral scanning method was performed to measure light transittance of the lenticules.The surface ultrastructure of the decellularized lenticules among different cross-linking groups was examined and compared with scanning electron microscope.The use of the human corneal lenticules was approved by an Ethics Committee of Chongqing Aier Ophthalmology Hospital (No.2019012). Written informed consent was obtained from each patient before surgery.Results:The release concentrations of decellularized corneal stroma lenticules were significantly different at 1 day, 7, 14, and 21 days among 0.5%, 3%, and 5% levofloxacin group ( P<0.05) or also among the 0.01 mmol EDC, 0.05 mmol EDC, and 0.25 mmol EDC cross-linked groups ( P<0.01). The drug release concentrations in 0.05 mmol EDC group were the highest at various time points, and the release time of the three cross-linked groups lasted until 21 days after release concentrations of decellularized corneal stroma lenticules.The drug release concentrations in cross-linked groups and non-crosslinking group were gradually declined with the prolong of drug-loading time, showing a significant difference at different time points ( P<0.05). The transmittance of the lenticules was (88.68±1.19)% and (91.55±1.16)% in the non-crosslinking group and normal group, respectively, with no significant difference ( P>0.05). The average transmittance of the lenticules was significantly reduced in the drug-loaded groups compared with the normal group ( P<0.05). The smaller collagen fiber voids and closely arranged collagen fibers were displayed in the cross-linking groups under the scanning electron microscope with the best effect in the 0.25 mmol EDC group. Conclusions:EDC/NHS cross-linking can improve the drug-loading effect of decellularized corneal stromal lenticules probably by lessening collagen fiber voids.The drug-loaded cross-linked decellularized corneal stromal lenticules have a good drug release effect in vitro.

Objective To investigate the value of rosuvastatin in alleviating early inflammatory reaction and in preventing early recurrence of persistent atrial fibrillation (AF) after catheter ablation treatment. Methods A total of 84 patients with persistent AF who had received catheter ablation were enrolled in this study. The patients were randomly and equally divided into group A (n = 42, study group) and group B (n = 42, control group). Rosuvastatin therapy (10 mg/d, 42 patients) was employed in the patients of group A, while no medication was used in the patients of group B. One month after the ablation treatment, the serum lipid level, hs-CRP and IL-6, as well as the recurrence rate of all kinds of arrhythmia were determined. The preoperative and postoperative levels of inflammatory markers were also determined, the results were compared between the two groups, and its correlation with the early recurrence of AF was evaluated. Results One month after the ablation treatment, the levels of inflammatory markers, including hs-CRP and IL-6, in the study group were significantly lower than those in the control group, as well as lower than those determined before treatment, while in the control group the serum hs-CRP and IL-6 levels became significantly higher than the preoperative ones. Sinus rhythm was successfully maintained in 29 cases (69%) of the study group and in 25 cases (59.5%) of the control group, while the difference was not statistically significant (P = 0.362). The patients of the study group were further divided into non-recurrence sub-group (n = 29) and recurrence sub-group (n = 13). The reduction in inflammatory marker level in the non-recurrence sub-group was greater than that in the recurrence sub-group although the difference was not statistically significant. Conclusion There is remarkable inflammatory reactions during the early period after catheter ablation. Rosuvastatin can effectively relieve the degree of inflammatory reaction, although it has only a slight effect in reducing the early recurrence rate after catheter ablation of AF. The greater the inflammatory markers levels are reduced, the lower the recurrence rate of AF will be, although the difference is not statistically significant.
