Objective To explore the efficacy of bilateral facial muscle training combined with visual electromyography biofeedback on facial nerve function recovery in patients with idiopathic facial nerve palsy. Methods Patients with idiopathic facial nerve palsy admitted to Shanghai Fifth People’s Hospital, Fudan University from July 2022 to July 2024 were selected and randomly divided into a control group and an intervention group. The control group received conventional physical factor therapy, while the intervention group received bilateral facial muscle training combined with visual electromyography biofeedback therapy based on the control group’s regimen. After 20 treatment sessions, the total effective rate, the House-Brackmann (H-B) facial nerve grading system, the Sunnybrook Facial Grading System (SFGS) score, and the average value ratio of maximal amplitudes of bilateral frontalis and zygomaticus muscles were compared between the two groups. Results A total of 90 patients were included, 45 in each group. After 20 treatment sessions, the total effective rate was significantly higher in the intervention group than in the control group (84.4% vs 75.6%, P＝0.003). Compared with the control group, the intervention group demonstrated a significantly lower H-B grade (P＝0.003) and a higher SFGS score (P＝0.001). The average value ratios of maximal amplitudes of the affected versus healthy side frontalis (P＝0.013) and zygomatic (P＝0.022) muscles were higher in the intervention group than in the control group. Conclusions Bilateral facial muscle training combined with visual electromyography biofeedback is an effective approach for treating idiopathic facial nerve palsy, effectively promoting the recovery of facial nerve function, and improving facial symmetry and facial muscle function.

Objective:To investigate frailty in older patients with comorbidities and explore related risk factors.Methods:A cross-sectional study was conducted with an enrollment of 746 patients aged 65 years or older with comorbidities in the Wanshoulu Road area of Beijing from April 2019 to December 2020.A total of 617 patients with comorbidities were finally included, aged(85.6±4.8)years, including 358 women(58.0%); According to the FRAIL scale, 617 patients with comorbidities were divided into a frail group(156 cases, 25.3%)and a non-frail group(461 cases, 74.7%). Demographic data and information on comorbidities were collected.Univariate and multivariate Logistic regression analyses of risk factors were conducted.Results:Among 617 patients with comorbidities, the common chronic diseases in descending order were hypertension(497 cases, 80.6%), coronary heart disease(375 cases, 60.8%), osteoporosis(357 cases, 57.9%), osteoarthritis(281 cases, 45.5%), type 2 diabetes(211 cases, 34.2%), stroke and/or transient ischemic attack(193 cases, 31.3%), chronic lung disease(144 cases, 23.3%), tumor(133 cases, 21.6%), chronic kidney disease(92 cases, 14.9%), and heart failure(58 cases, 9.4%). Univariate logistic regression analysis showed that age, type 2 diabetes, coronary heart disease, heart failure, chronic lung disease, stroke/transient ischemic attack, cancer and osteoarthritis were influencing factors for frailty( P<0.05). Multivariate logistic regression analysis showed that age, type 2 diabetes, heart failure, chronic lung disease, cancer and osteoarthritis were risk factors for frailty( OR=1.076, 1.806, 3.275, 3.371, 1.640, 2.227, all P<0.05). Conclusions:Old age, type 2 diabetes, heart failure, chronic lung disease, tumor and osteoarthritis are closely related to frailty in elderly patients with comorbidities.Proactive and effective prevention and intervention should be instituted to target risk factors for frailty to reduce the occurrence of adverse outcomes.

BACKGROUND: Changes in thyroid hormone levels are commonly recognized characters among the elderly, which were reported to potentially influence incident frailty. Therefore, we examined the cross-sectional associations of thyroid hormones (THs) with frailty as well as the five components characterizing frailty (fatigue, resistance, ambulation, number of illnesses, and loss of weight) among the oldest-old. METHODS: Four hundred and eighty-seven community-dwelling oldest-old from a local community in Haidian District, Beijing, participated in our recruitment campaign between April 2019 and May 2020. The primary outcomes were a definitive diagnosis of frailty according to the FRAIL scale (Fatigue, Resistance, Ambulation, Illnesses, Loss of weight) and a positive score for each frailty subdomain. Demographic information (age, sex, marital status, and educational status), comorbidities, and details on the participants' lifestyles were recorded. Serum THs including free triiodothyronin (fT3), triiodothyronine (T3), free thyroxine (fT4), and thyroxine (T4) and thyroid stimulating hormone (TSH) levels were also measured at the beginning of our study. Logistic regressions were conducted to screen for potential risk factors for frailty and its subdomains. RESULTS: Among the total 487 subjects at enrollment, 60 (12.23%) of them were diagnosed with subclinical hypothyroidism and 110 (22.59%) of the total population scored positive for frailty. Logistic regression analyses adjusted for all potential confounders, showed that frailty was significantly associated with the serum TSH concentration (odds ratio [OR]: 1.06), fT3 concentration (OR: 0.54), and subclinical hypothyroidism score (OR: 2.18). The association between fT4 and frailty was absent in our observational study. The fT3/fT4 ratio characterizing peripheral hormone conversion was also tested to be correlated with frailty. CONCLUSION Subclinical hypothyroidism, higher TSH level, lower fT3 level, and decreased fT3/fT4 ratio were all associated with frailty assessed by the FRAIL scale among the community-dwelling oldest-old, suggesting a relevant role of thyroid function in aging. Future longitudinal studies are warranted to determine the casual relationship between thyroid dysfunction and frailty in the oldest-old.

Objective:To examine the status of career decision-making and its influencing factors among nursing postgraduate students.Methods:From October 2018 to December 2019, 249 nursing postgraduate students from universities were selected by convenience sampling method and were investigated using general information questionnaire, Career Decision-making Difficulties Questionnaire, Professional Identity Scale and Proactive Personality Scale.Results:The score of postgraduate nursing students' career decision-making difficulties was (58.10±8.98). Correlation analysis showed that the score of the career decision-making difficulties was positively correlated with professional identity and proactive personality of nursing postgraduate students ( r=0.187, 0.581, P<0.01). Multiple linear regression analysis showed that gender, whether they had received career counseling and proactive personality scores were influencing factors of career decision-making difficulties which explained 38.0% of the total variation. Conclusions:The career decision-making difficulties of nursing postgraduate students is at a medium level. Educators can reduce the career decision-making difficulties of nursing postgraduate students by conducting career counseling, improving professional identity or enhancing career initiative.

Objective: To explore the effect of mindfulness traits on sleep quality of college students, and to investigate the mediating mechanism of cognitive emotion regulation and anxiety for mindfulness trait factors, and sleep quality in college students. Methods: Totally 397 college students from five colleges were investigated using Five Facet Mindfulness Questionnaire, Cognitive Emotion Regulation Questionnaire, Self-Rating Anxiety Scale and Pittsburgh Sleep Quality Index.SPSS 22.0 version and Bootstrap method were used to analysis data and test intermediate effect. Results: (1)The total score of mindfulness trait and the score of describe, act with awareness and non-judge factors in mindfulness traits were(118.44±9.38), (24.82±3.87), (27.41±5.53) and (25.07±4.60), respectively.The total score of sleep quality was (5.57±2.62), and it was negatively related to the above three factors (r=-0.13--0.37, all P<0.05). (2)Anxiety played a complete mediating role between describe factor and sleep quality.Negative cognitive emotion regulation and anxiety played multiple mediating roles between the total score of mindfulness trait, the act with awareness factor and sleep quality.Negative cognitive emotion regulation and anxiety played a complete chain mediated role between non-judge factor and sleep quality. Conclusion The describe, act with awareness and non-judge factors in mindfulness traits can affect sleep quality through mediation of negative cognitive emotion regulation and / or anxiety.

Bacterial ghosts are bacterial cell envelopes devoid of cytoplasmic contents while maintaining their cellular morphology, which can be used as a new vaccine and delivery vector. In this study, a clinical isolate of avian pathogenic Escherichia coli (APEC) strain DE17 was used to prepare bacterial ghost through three different ways. The results showed that the cleavage efficiency of DE17 bacterial ghost was 99.9% with the lysis plasmid containing the PhiX174 lysis gene E. Scanning electron microscopy showed that transmembrane tunnels were formed in the middle or both ends of the cell envelope of DE17. Furthermore, the DE17 bacterial ghost was prepared with one of cell penetrating peptides (CPPs) named MAP (KLALKLALKALKAALKLA), which will completely inactivate DE17 (OD₆₀₀=0.1) by 10 μmol/L MAP. The cell envelope showed a gully-like structure and obvious transmembrane tunnels were not found through the SEM. However, the DE17 could not be lysed by importing the lysis plasmid (pBV220-MAP), which was used to express MAP. The present study will benefit for research on bacterial ghost preparation methods and provide a reference for biosafety of bacterial ghost vaccines.
