Purpose: The study aims to confirm the mediating effect of nursing professional pride in the relationship between nursing practice environment, nursing performance, and retention intention. Methods: A descriptive cross-sectional survey was conducted from December 13 to 31, 2021, involving 127 nurses. The following statistical analysis was conducted: t-test, ANOVA, Scheffé test, Pearson's correlation coefficient analysis, and Hayes Process Macro Model 4 (to test the mediating effect). Results: Nursing practice environment showed a significant positive correlation with nursing performance, retention intention, and nursing professional pride. Nursing practice performance showed a positive correlation with retention intention and nursing professional pride, and retention intention showed a significant positive correlation with nursing professional pride. The mediating effect of nursing professional pride was found in the effect of nurses' nursing practice environment on their retention intention. In addition, the mediating effect of nursing professional pride was found in the effect of nurses' nursing practice performance on their retention intention. Conclusion Through this study, it was confirmed that nursing professional pride is a major A factor affecting retention intention in the hospital. Therefore, in order to increase nurses' retention intention to remain in Hospital, the basis of basic data was presented for strategy development.

Patients with non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) amplification or sensitive muta-tions initially respond to the tyrosine kinase inhibitor gefitinib, however, the treatment becomes less effective over time by resis-tance mechanism including mesenchymal-epithelial transition (MET) overexpression. A therapeutic strategy targeting MET and EGFR may be a means to overcoming resistance to gefitinib. In the present study, we found that picropodophyllotoxin (PPT), derived from the roots of Podophyllum hexandrum, inhibited both EGFR and MET in NSCLC cells. The antitumor efficacy of PPT in gefitinib-resistant NSCLC cells (HCC827GR), was confirmed by suppression of cell proliferation and anchorage-independent colony growth. In the targeting of EGFR and MET, PPT bound with EGFR and MET, ex vivo, and blocked both kinases activity. The binding sites between PPT and EGFR or MET in the computational docking model were predicted at Gly772/Met769 and Arg1086/Tyr1230 of each ATP-binding pocket, respectively. PPT treatment of HCC827GR cells increased the number of annexin V-positive and subG1 cells. PPT also caused G2/M cell-cycle arrest together with related protein regulation. The inhibition of EGFR and MET by PPT treatment led to decreases in the phosphorylation of the downstream-proteins, AKT and ERK. In addition, PPT induced reactive oxygen species (ROS) production and GRP78, CHOP, DR5, and DR4 expression, mitochondrial dysfunc-tion, and regulated involving signal-proteins. Taken together, PPT alleviated gefitinib-resistant NSCLC cell growth and induced apoptosis by reducing EGFR and MET activity. Therefore, our results suggest that PPT can be a promising therapeutic agent for gefitinib-resistant NSCLC.

Purpose: To develop a self-reported communication competency scale for patients with schizophrenia. Methods: Twenty-nine preliminary items were selected from 42 candidate items derived from literature review and qualitative interviews using content validity analysis of expert opinions to evaluate 637 patients’ schizophrenia communication competence. Data from 383 individuals were analyzed. Confirmatory factor analysis was conducted using data of 280 individuals. The final dataset included data from 254 participants. Data were subjected to exploratory and confirmatory factor analyses using SPSS and AMOS 24.0. Results: After evaluating the model fit index for the last 24 items, the following results were obtained: x2=633.95 (p<.001), x2/df (degree of freedom)=2.26, SRMR=0.04, RMSEA=0.06, TLI=0.93, CFI=0.94, NFI=0.96. Therefore, this tool’s suitability was evaluated as acceptable. The final scale comprised 24 items and 3 subscales that could measure basic, interpersonal, and communicative expression of patients with schizophrenia. Conclusion A self-reported communication competency scale was developed for patients with schizophrenia. It is expected to help measure the effectiveness of intervention programs to improve communication among patients with schizophrenia.

PURPOSE: The present research was done to examine the fundamental significance and structure of conflict experience of nurses in hospital nursing organizations.METHODS: This qualitative research was conducted by analyzing data collected through in-depth interviews based on Colaizzi's (1978) method of analysis, one of the phenomenological methods of analysis.RESULTS: Statements from the 12 study participants demonstrate two key topics “accumulation of conflicts” and “manifestation of new conflicts” as well as seven sub-topics including “being forced to comply”, “Lack of respect and consideration”, “unsatisfactory conflict management by the leaders”, “continuous and overwhelming vicious cycle”, “prevalence of self-defensive egotism”, “difficult to accept differences”, and “incapable of responding to the structural changes of nursing workforce”.CONCLUSION: Resolving the dysfunctional conflicts in hospital nursing organizations requires not only improvement in the organizational culture of individuals and nursing organizations, but also legal and institutional measures in addition to new attempts to integrate education and research findings from relevant fields of studies.

Bioassay-guided fractionation of the roots of Asarum sieboldii led to the isolation of the six compounds methylkakuol (1), sesamin (2), asarinin (3), xanthoxylol (4), and (2E,4E,8Z,10E/Z)-N-(2-methylpropyl) dodeca-2,4,8,10-tetraenamide (5/6). Among the isolates, xanthoxylol (4) exhibited significant cytotoxicity against human breast cancer cells MCF-7 and MDA-MB-231 in vitro with IC₅₀ values of 9.15 and 13.95 µM, respectively.

OBJECTIVES: Osteoporosis is a disease of bones that is thought to result from an imbalance between bone resorption and bone formation. Although osteoporosis itself has no symptoms, osteoporosis caused by osteoclasts leads to an increased risk of fracture. Here we examined the effects of cornus officinalis on receptor activator of nuclear factor-kappaB ligand (RANKL)-mediated osteoclast differentiation. METHODS: We evaluated the effects of cornus officinalis on RANKL-induced osteoclast differentiation from bone marrow-derived macrophages (BMMs) and performed a cytotoxicity assay, reverse transcriptase-polymerase chain reaction (RT-PCR), and Western blot analysis. RESULTS: Cornus officinalis significantly inhibits RANKL-mediated osteoclast differentiation in a dose-dependent manner, but without cytotoxicity against BMMs. The mRNA expression of tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), c-Fos, and nuclear factor of activated T cells cytoplasmic 1 (NFATc1) in BMMs treated with RANKL was considerably inhibited by cornus officinalis treatment. Also, cornus officinalis inhibits the protein expression of c-Fos and NFATc1. Cornus officinalis greatly inhibits RANKL-induced phosphorylation of p38 and c-JUN N-terminal kinase (JNK). Also, cornus officinalis significantly suppresses RANKL-induced degradation of I-kappaB. CONCLUSIONS: Taken together, our results suggest that cornus officinalis may be a useful the treatment of osteoporosis.

Aberrant activation of hepatocyte growth factor/scatter factor (HGF/SF) and its receptor, Met, is involved in the development and progression of many human cancers. In the cell-based screening assay, (-)epigallocatechin-3-gallate (EGCG) inhibited HGF/SF-Met signaling as indicated by its inhibitory activity on HGF/SF-induced cell scattering and uPA activation (IC50 = 15.8 microg/ml). Further analysis revealed that EGCG at low doses specifically inhibited HGF/SF-induced tyrosine phosphorylation of Met but not epidermal growth factor (EGF)-induced phosphorylation of EGF receptor (EGFR). On the other hand, high-dose EGCG decreased both Met and EGFR proteins. We also found that EGCG did not act on the intracellular portion of Met receptor tyrosine kinase, i.e., it inhibited InlB-dependent activation of Met but not NGF-induced activation of Trk-Met hybrid receptor. This inhibition decreased HGF-induced migration and invasion by parental or HGF/SF-transfected B16F10 melanoma cells in vitro in either a paracrine or autocrine manner. Furthermore, EGCG inhibited the invasion/metastasis of HGF/SF-transfected B16F10 melanoma cells in mice. Our data suggest the possible use of EGCG in human cancers associated with dysregulated paracrine or autocrine HGF/SF-Met signaling.
