The keywords clustering were "depression", "functional connectivity", "cognitive reserve", "cognitive function", "physical activity", "recommendations", "dementia prevention", " behavioral disorders", "primary care", "early diagnosis", and "community-based study". Keywords with the highest citation bursts include "physical activity", "framework", "preclinical Alzheimer's disease", "future dementia", and "late life depression". Conclusions: Parallel to the growth trend, the range of research scopes and topics is expanding steadily, focusing on early screening and prevention, negative emotion, and symptom management, broadening researchers' perspectives, which can provide reference and guidance for nursing researchers to conduct research.

Individual stigma in people with severe mental illness: Associations with public stigma, psychological capital, cognitive appraisal and coping orientations.

INTRODUCTION: The reason why some people with severe mental illness (SMI) maintain positive self-identity, while some are affected by the stigmatized environment is unclear. AIMS: To describe the status of individual stigma and explore the relationship between self-stigma, stigma resistance and related variables in people with SMI. METHODS: A cross-sectional study was conducted from April 2021 to March 2022. The Chinese version of Internalized Stigma of Mental Illness Scale and Stigma Resistance Scale were used to assess individual stigma. Perceived public stigma, psychological capital, stigma stress appraisal and coping orientations were also measured by scales. Data was provided by 422 patients with schizophrenia or bipolar disorder, from one psychiatric hospital and four community healthcare centers in China. A structural equation model was applied for analysis. RESULTS: The total mean scores of self-stigma and stigma resistance were (2.06 ± 0.65), and (3.95 ± 0.84). Perceived public stigma was the primary condition for constructing individual stigma, which indirectly affected self-stigma (ß = 0.268) and stigma resistance (ß = -0.145). Stigma stress appraisal mediated the transformation of public stigma into individual, which had direct and indirect effects on self-stigma (ß = 0.417, 0.166), and an indirect effect on stigma resistance (ß = -0.374). Secrecy positively affected self-stigma (ß = 0.117), while positive coping positively affected stigma resistance (ß = 0.380). Psychological capital significantly directly impacted individual stigma. CONCLUSIONS: Findings highlighted how public stigma determines the degree to which patients with SMI deal with stigma stress appraisal, and how this influences individuals. Anti-stigma programs and interventions to improve individuals' psychological capital and coping capabilities should be emphasized.

The Stigma Resistance Scale for people with mental illness: Transcultural adaption and validation of the Chinese version.

The understanding of stigma resistance and its prevalence is limited due to the limitation of existing measures. This study aims to modify the Stigma Resistance Scale (SRS) and assess the psychometric properties of Chinese patients with mental illness. Seven experts were invited to assess the content validity of the Chinese version of the SRS (C-SRS), which has been translated and adapted into Chinese. Convenience samples were included from two psychiatric hospitals and three community healthcare centers in Beijing, China. A total of 484 patients completed the survey from November 2020 to July 2021. Samples were randomized into two parts exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). EFA (n = 242) yielded three factors with Cronbach's α of 0.932 for the total scale, and 0.835, 0.877, and 0.858 for the subscales. CFA (n = 242) revealed good model fit (χ2 /df = 2.190, RMSEA = 0.070). The domain-total correlation scores were 0.834-0.939. The correlation coefficient of test-retest ranged from 0.726 to 0.887. The correlation coefficient between the C-SRS and Stigma Resistance subscale of the Internalized Stigma of Mental Illness scale was 0.399. This study found that the C-SRS has evidence of excellent reliability and validity for assessing stigma resistance. It could be used in Chinese people with mental illness to identify and address stigma resistance.

China's cultivation of master nursing specialist: A qualitative content analysis of the stakeholders.

AIM: To assess the Master of Nursing Specialist (MNS) in China from the perspectives of relevant stakeholders to assist the sustained development of the MNS program. BACKGROUND: With the growing demand for quality nursing care, the cultivation of higher-level specialized nursing professionals continues to be challenging. DESIGN: A descriptive qualitative study. METHODS: The study used a convenience sampling method. Stakeholders of MNS education in the interviews included graduates of the MNS program, hospital administrators and healthcare policymakers. The individual semi-structured interviews were conducted via telephone, online interview, or face-to-face between April and December 2020. All interview materials were audio-recorded and transcribed verbatim and were analyzed using the qualitative content analysis approach. RESULTS: A total of 27 stakeholders completed the interviews, including 11 MNS graduates, 11 hospital administrators and 5 healthcare policymakers. Attitudes about and confirmation of the MNS program were collected as well as suggestions about further optimization. Three themes or categories were identified: the paradox of MNS prospects, current conditions of MNS education and strategic actions for further optimization. CONCLUSIONS: Our findings were based on the relevant stakeholders' views toward MNS education, providing a multidimensional view when combined. The results reflected the current state and future direction of MNS education in China, which will help sustain the development of MNS programs. The practice and experience in China will enlighten other developing countries with similar backgrounds.

Bibliometric analysis of the Doctor of Nursing Practice dissertations in the ProQuest Dissertations and Theses database.

AIMS: To examine the distributed characteristics and explore the research themes of Doctor of Nursing Practice (DNP) dissertations during the past two decades. DESIGN: A descriptive statistical and visualization bibliometric analysis was conducted. METHODS: Doctor of Nursing Practice dissertations submitted between January 2005 and June 2021 were collected from the ProQuest Dissertations and Theses database. A descriptive statistical analysis was conducted to calculate the distribution of the DNP dissertations by granting institution and the published year of publications. The VOSviewer 1.6.13 was used to explore the bibliometric networks and research priorities of the DNP dissertations. RESULTS: A total of 4989 DNP dissertations from 90 universities were included in this study, all from the United States. The number of DNP dissertations showed an upward trend, with steady growth from 2005 to 2014 and rapid growth after 2015. The DNP studies focused on five areas: health care management in clinical nursing, advanced practice in nursing education and health education, public health problems, mental health care for adolescents and nurses and the older people care and long-term care. CONCLUSION: Parallel to the numerical increase in DNP dissertations is a steady expansion in the range of research topics and scopes, which is aligned with specific specializations of the DNP. Many are interdisciplinary and employ techniques imported from the fields of public health, psychology and social sciences, resulting in nursing educators and practitioners continually broaden their subject perspectives. IMPACT: Knowing where, when and why DNP research trends developed will help nursing educators to further develop DNP education and optimize DNP programs in the future, such as paying more attention to the nursing practice. Moreover, this study will inspire DNP students and researchers to expand their subject perspectives and broaden the research scope to solve nursing practice problems based on interdisciplinary theories and methods.

[Clinical efficacy of different rehabilitation modes for lumbar degenerative diseases after operation].

OBJECTIVE: To compare clinical effects of different postoperative rehabilitation modes on lumbar degenerative diseases, and explore influence of rehabilitation mode and other factors on postoperative effect. METHODS: From June 2013 to July 2016, totally 900 patients were admitted from nine tertiary hospitals in Beijing to perform single segment bone grafting and internal fixation due to lumbar degenerative diseases were prospectively analyzed. There were 428 males and 472 females, the age of patient over 18 years old, with an average of (51.42±12.41) years old;according to patients' subjective wishes and actual residence conditions, all patients were divided into three groups, named as observation group 1 (performed integrated rehabilitation approach and orthopedic treatment model intervention), observation group 2 (performed integrated rehabilitation approach and orthopedic treatment, classified rehabilitation model intervention), and control group(performed routine rehabilitation model intervention). Visual analogue scale(VAS), Oswestry Disability Index(ODI) and Japanese Orthopaedic Association (JOA) were used to evaluate postoperative efficacy among three groups at 24 weeks. Possible factors affecting the postoperative efficacy including age, age grouping, gender, body mass index (BMI), BMI grouping, education level, visiting hospital, payment method of medical expenses, preoperative complications, preoperative JOA score, clinical diagnosis, surgery section, operative method, intraoperative bleeding volume, postoperative complications and rehabilitation mode were listed as independent variables, and postoperative ODI score at 24 weeks as dependent variables. Univariate analysis was used to analyze relationship between influencing factors and postoperative efficacy. Multiple linear regression was used to analyze relationship between influencing factors, rehabilitation mode and postoperative ODI score at 24 weeks, in further to find out the main reasons which affect postoperative efficacy, and to analyze impact of rehabilitation mode on postoperative efficacy. RESULTS: All patients were followed up for 24 weeks after operation. All incisions healed at stage I with stable internal fixation. (1)Evaluation of postoperative efficacy:① There were no statistical differences in preoperative VAS and ODI among three groups(P>0.05), the degree of pain and dysfunction decreased among three groups after operation, and had differences in postoperative VAS and ODI among three groups (P<0.05). There were no significant differences between observation group 1 and observation group 2(P>0.05); while compared with observation group 1 and control group, observation group 2 and control group, there were significant differences (P<0.05). ②The function among three groups were improved in varying degrees after operation. There was difference in JOA score among three groups before operation and 24 weeks after operation (P<0.05). There were no difference in JOA score among three groups between observation group 1 and observation group 2 (P>0.05);while compared with observation group 1 and control group, observation group 2 and control group, there were significant differences (P<0.05). (2)Influencing factors at 24 weeks after operation:①Univariate analysis showed gender, age, age grouping, education level, preoperative complications, clinical diagnosis, operative section, operative method, preoperative JOA score and rehabilitation mode had statistical significance with postoperative ODI score at 24 weeks (P<0.05). BMI, BMI grouping, payment method of medical expenses, visiting hospital, intraoperative bleeding volume, postoperative complications had no statistical significance with postoperative ODI score at 24 weeks (P<0.05).②Multivariate analysis results showed gender, rehabilitation mode, age, preoperative JOA score entered the equation eventually, stepwise multiple linear equation obtained had statistical significance (F=12.294, P= 0.000). Among rehabilitation mode, standardized regression coefficient of the integrated rehabilitation approach and orthopedic treatment with classified rehabilitation model was absolute value of the largest (0.176), which had the greatest influence on postoperative curative effect. The degree of dysfunction in control group was higher than that in observation group 1 and observation group 2. Postoperative dysfunction was more severe in males than that of in females. Older age has higher degree of dysfunction after operation. Lower preoperative JOA score has higher degree of dysfunction after operation. CONCLUSION: Preoperative JOA score, gender, age could predict postoperative clinical effects of lumbar degenerative diseases in varying degrees treated with single level bone graft fusion and internal fixation. Different rehabilitation modes could improve clinical effects. Intergrated rehabilitation orthopedic treatment model and integrated rehabilitation approach and orthopedic treatment with classifiedrehabilitation model are superior to conventional rehabilitation model in improving patients' postoperative function and relieving pain, which is worthy of promoting in clinical.

Health personnel-targeted education interventions on inpatient suicide prevention in general hospitals: A scoping review.

BACKGROUND: Inpatient suicide is an important part of patient safety management in general hospitals. Incidence of inpatient suicide can be decreased by health personnel mastering inpatient suicide prevention strategy. To enhance health personnel's inpatient suicide prevention strategy, education intervention is a common method. Educational interventions in the researches varied in contents, duration and outcome measurements. However, there has been not synthesis of education interventions targeting health personnel on inpatient suicide prevention. OBJECTIVE: Prevention of inpatient suicide is a critical priority in patient safety management in general hospitals. Incidence of inpatient suicide can be decreased by effective strategies mastered by health personnel through education interventions. Educational interventions in researches varied in contents, duration and outcome measurements. We aimed to review education interventions targeting health personnel on inpatient suicide prevention. METHODS: A scoping review was used to analyze existing researches on education interventions targeting health personnel focusing on inpatient suicide prevention in general hospitals. Cochrane Library, PubMed, Embase, CINAHL, China National Knowledge Infrastructure, WanFang, and Chinese Scientific Journal Database were searched in Oct 2019. According to the inclusion and exclusion criteria, the searched studies were screened by two reviewers. And then, two researchers conducted the data extraction independently by using a table format, including the first author, year of publication, study design, participants, education intervention, etc. RESULTS: Twelve studies were included in this scoping review. The contents of education interventions on inpatient suicide prevention included three aspects: suicide knowledge, suicide assessment, and skills for coping with suicide. The duration of education interventions ranged from 1.5-h to 32.0-h. The effects of education interventions were mainly focused on participants' knowledge, attitudes and skills of suicide prevention. CONCLUSION: The evidence showed that education interventions on inpatient suicide prevention had positive impact on health personnel's knowledge, attitude and skills about inpatient suicide prevention in general hospitals. However, the best health personnel-targeted education intervention on inpatient suicide prevention in general hospitals was yet to be determined. In the future, it is necessary to combine evidence in this review and the actual condition in clinical practice.

Down-Regulation of miR-301a-3p Reduces Burn-Induced Vascular Endothelial Apoptosis by potentiating hMSC-Secreted IGF-1 and PI3K/Akt/FOXO3a Pathway.

Vascular endothelium dysfunction plays a pivotal role in the initiation and progression of multiple organ dysfunction. The mesenchymal stem cell (MSC) maintains vascular endothelial barrier survival via secreting bioactive factors. However, the mechanism of human umbilical cord MSC (hMSC) in protecting endothelial survival remains unclear. Here, we found IGF-1 secreted by hMSC suppressed severe burn-induced apoptosis of human umbilical vein endothelial cells (HUVECs) and alleviated the dysfunction of vascular endothelial barrier and multiple organs in severely burned rats. Severe burn repressed miR-301a-3p expression, which directly regulated IGF-1 synthesis and secretion in hMSC. Down-regulation of miR-301a-3p decreased HUVECs apoptosis, stabilized endothelial barrier permeability, and subsequently protected against multiple organ dysfunction in vivo. Additionally, miR-301a-3p negatively regulated PI3K/Akt/FOXO3 signaling through IGF-1. Taken together, our study highlights the protective function of IGF-1 against the dysfunction of multiple organs negatively regulated by miR-301a-3p, which may provide the theoretical foundation for further clinical application of hMSC.

Treatment with IL-19 improves locomotor functional recovery after contusion trauma to the spinal cord.

BACKGROUND AND PURPOSE: IL-19 skews the immune response towards a Th2 type and appears to stimulate angiogenesis. In the current study, we tested if IL-19 treatment could reduce secondary injury and improve functional recovery after contusion spinal cord injury (SCI). EXPERIMENTAL APPROACH: Firstly, mice were given a moderate-severe thoracic SCI at the T9-10 level and expression of IL-19 and its receptor was measured in the injured spinal cord. Then SCI mice were treated with mouse recombinant IL-19 and its blocking antibody to investigate the therapeutic effect of IL-19. KEY RESULTS: Protein expression of IL-19 and its receptor IL-20R1 and IL-20R2 was up-regulated in the injured spinal cord of mice. IL-19 treatment promoted the recovery of locomotor function dose-dependently and reduced loss of motor neurons and microglial and glial activation following SCI. Treatment of SCI mice with IL-19 attenuated macrophage accumulation, reduced protein levels of TNF-α and CCL2 and promoted Th2 response and M2 macrophage activation in the injured region. Treatment of SCI mice with IL-19 promoted angiogenesis through up-regulating VEGF in the injured region. Treatment of SCI mice with IL-19 up-regulated HO-1 expression and decreased oxidative stress in the injured region. The beneficial effect of IL-19 was abolished by coadministration of the blocking antibody. Additionally, IL-19 deficiency in mice delayed the recovery of locomotor function following SCI. CONCLUSIONS AND IMPLICATIONS: IL-19 treatment reduced secondary injuries and improved locomotor functional recovery after contusion SCI, through diverse mechanisms including immune cell polarization, angiogenesis and anti-oxidative responses.

Neuroprotective effects of curcumin alleviate lumbar intervertebral disc degeneration through regulating the expression of iNOS, COX­2, TGF­ß1/2, MMP­9 and BDNF in a rat model.

Curcumin is a natural product with antimutagenic, antitumor, antioxidant and neuroprotective properties. However, to the best of our knowledge, curcumin has yet to be investigated for the treatment of lumbar intervertebral disc degeneration LIDD). The aim of the present study was to investigate whether curcumin can alleviate LIDD through regulating the expression of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)­2, transforming growth factor (TGF)­ß1/2, matrix metalloproteinase (MMP)­9 and brain­derived neurotrophic factor (BDNF) in a rat model of LIDD. The results of the present study suggest that pretreatment with curcumin can prevent the development of LIDD in rats. It was revealed that treatment with curcumin significantly reduced interleukin (IL)­1ß and IL­6, iNOS, COX­2 and MMP­9 levels in rats with LIDD. In addition, treatment with curcumin reduced the mRNA expression levels of TGF­ß1 and TGF­ß2, whereas it increased the mRNA expression levels of BDNF in rats with LIDD. In conclusion, the present findings indicate that curcumin may exert protective effects on LIDD development, exerting its action through the regulation of iNOS, COX­2, TGF­ß1/2, MMP­9 and BDNF.

[Effects of acupuncture intervention at different stages on urinary function reconstruction of neurogenic bladder after spinal cord injury].

OBJECTIVE: To explore the effects of early intervention of acupuncture on urinary function reconstruction of neurogenic bladder after spinal cord injury, so as to find the optimal treatment timing of acupuncture. METHODS: Fifty-three patients of neurogenic bladder after spinal cord injury were randomly divided into a prior-to-catheter group (25 cases) and a posterior-to-catheter group (28 cases). For the prior-to-catheter group, one week before the removal of catheter, acupoints on the abdomen and back such as Guanyuan (CV 4), Zhongji (CV 3), Baliao (Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33), Xialiao (BL 34), Jiaji (EX-B 2) and acupoints at distal end such as Zusanli (ST 36) and Sanyinjiao (SP 6) were selected; after the catheter removal, simple method. of water column was used to measure bladder capacity pressure to classify the type of bladder, and then different acupuncture manipulations were given; intermittent catheterization was performed if condition was allowed. The posterior-to-catheter group applied identical treatment after removal of catheter as the prior-to-catheter group. The treatment was given 5 times per week; after one-month treatment, five aspects including the time of first effective urination, time of establishing reflex urination, average residual volume of urine, time of residual urine less than 100 mL and quality of life (QOL) were evaluated. RESULTS: After treatment, the time of first effective urination, time of establishing reflex urination, average residual volume of urine and time of residual urineless than 100 mL in the prior-to-catheter group were all superior to those in the posterior-to-catheter group (all P<0. 05) ; the score of QOL was improved in two groups after treatment (both P<0. 01), but the difference between two groups was not statistically significant (P>0. 05); each index of urination function was not significant among patients with different injured segments of spinal cord (all P>0. 05). CONCLUSION: The early intervention of acupuncture (prior to catheter) has obvious improving function on establishing balanced bladder in patients with neurogenic bladder after spinal cord injury, which is superior to acupuncture intervention after removal of catheter, however, the effects of different injured segments on establishing balanced bladder are not different.

Hypoxia-Inducible Factor 1-Alpha Regulates Cancer-Inhibitory Effect of Human Mesenchymal Stem Cells.

Mesenchymal stem cells (MSCs) have been shown to be able to inhibit cancer cells growth. In this study, we investigate the role and the molecular mechanism of hypoxia-inducible factor 1-alpha (HIF-1α) in inhibition of cancer cell proliferation by human MSCs through depletion and overexpression of HIF-1α in human MSCs. We found that the cell culture medium from HIF-1α-depleted Z3 cells significantly promotes breast cancer MCF-7 cell proliferation and colony formation. The expression of p21 is increased in MCF-7 cells, but p53 level remains unchanged. In contrast, the cultured medium from HIF-1α-overexpressed Z3 cells dramatically inhibits MCF-7 cell proliferation and colony formation. The expression of p21 is inhibited in MCF-7 cells, but p53 does not change. We conclude HIF-1α promotes inhibitory effect of human MCSs on breast cancer cell proliferation and colony formation. This process is tightly correlated with cell cycle protein p21 level in cancer cells.

Treatment and Rehabilitation of Knee Joints Straight Stiffness After Burns.

The knee release surgery and postoperative rehabilitation of patients after burns and knee straight stiffness were investigated. Eleven patients were treated for 16 side burns and knee stiffness who consisted of nine males and two females, aged 19 to 54 years (mean = 33.2). The duration of the patients' knee stiffness ranged from 8 to 26 months, with an average of 12.6 months. Their preoperative flexion ranged from 5° to 50°, with an average of 26.2°. Their preoperative Hospital for Special Surgery (HSS) knee scores ranged from 46 to 72 points, with an average of 55.8 points. All stiff knees were treated with release surgery, along with total release of intra-articular adhesion and excision of vastus intermedius. After the arthrolysis of the stiff knee joint, the tight skin was completely loose in the adhesions. The soft tissue contracture was not grafted, but the shade fascia was freed to increase skin ductility. All knee joints were released to more than 90° of flexion in the operation, and reversed fascia flaps were used to suture the loss of the deep fascia at the position of flexion of 90°. After the operation, the knee joint was fixed in flexion for 72 h while being actively cared for by early rehabilitation. Subsequently, the patient's skin coverage, joint motion, and joint function recovery were observed. Based on the follow-up of the patients for the following 16 to 36 months (mean = 25.7), the knee flexion of the patients ranged from 110° to 135°, with an average of 122.2° and 96° increase (P < 0.01). Furthermore, the patients had better skin ductility to meet the increase in joint flexion. HSS knee function scores at the end of follow-up ranged from 93 to 100 points, with an average of 97.5 points and an increase of 41.7 points (P < 0.01). The joint function improved significantly. The arthrolysis of straight stiff knee joints after burns can ease muscle contracture and free the shade fascia, thus avoiding the need to undergo skin grafting. Short-term fixation of the joints after surgery and active flexion rehabilitation may also be the key to improve skin ductility and joint function of the patients.

Genetic ablation of receptor for advanced glycation end products promotes functional recovery in mouse model of spinal cord injury.

Spinal cord injury (SCI) results in a loss of normal motor and sensory function, leading to severe disability and reduced quality of life. The aim of this work was to investigate the effect of receptor for advanced glycation end products (RAGE) deficiency on the function recovery in a mouse model of SCI. Mice received a mid-thoracic spinal contusion injury. Upregulation of RAGE protein expression in spinal cord tissue was evident at 12 h after SCI and continued at 2 and 5 days. Furthermore, we showed that locomotor recovery was improved and lesion pathology was reduced after SCI in RAGE-deficient mice. RAGE deficiency in mice attenuated apoptosis after SCI through inhibiting p53/Bax/caspase-3 pathway. RAGE deficiency in mice inhibited inflammation after SCI, marked by reduced myeloperoxidase activity, NFκB nuclear translocation, and TNF-α, IL-1ß, and IL-6 mRNA and protein levels. RAGE deficiency in mice exposed to SCI suppressed the upregulation of inducible nitric oxide synthase (iNOS) and gp91-phox and attenuated oxidative and nitrosative stresses, marked by reduced formation of malondialdehyde, reactive oxygen species, peroxynitrite (OONO(-)), and 3-nitrotyrosine. RAGE deficiency in mice exposed to SCI attenuated glial scar at the injury site, marked by decreased expression of glial fibrillary acidic protein. These data indicate that the RAGE plays an important role in the development of SCI and might provide a therapeutic target to promote recovery from SCI.
