Analysis of spiritual well-being status and influencing factors in patients with esophageal cancer: a cross-sectional study.

OBJECTIVE: To understand the status of spiritual well-being in patients with esophageal cancer and analyze its influencing factors. METHODS: A total of 187 patients with esophageal cancer (EC) from two grade A hospitals in Chengdu were selected and investigated by general data questionnaire, chronic disease function evaluation-spirituality scale 12 (FACIT-SP-12), general well-being scale (GWB), and Anderson symptom assessment scale gastrointestinal tract (MDASI-GI). RESULTS: The spiritual well-being score of patients with esophageal cancer was (25.13 ± 9.63). Spiritual well-being was positively correlated with general well-being and negatively correlated with symptom burden (P < 0.01). The results of multiple stepwise linear regression analysis showed that hobbies, disease stage, general well-being, and symptom burden were the main influencing factors for the spiritual well-being of esophageal cancer patients (P < 0.05), explaining 49.0% of the total variation. CONCLUSIONS: The spiritual well-being of patients with esophageal cancer is lower than the middle level, In addition, whether there is a hobby in life, disease stage, subjective well-being, and symptom burden are the main factors affecting the spiritual well-being of patients with EC. It is suggested that medical staff should take targeted care measures according to the influencing factors, so as to improve the spiritual well-being level of patients and improve the quality of life of patients.

Psychometric validation of the Chinese versions of the quality of communication questionnaires for cancer patients and their family caregivers.

BACKGROUND: Given the lack of valid and reliable instruments for evaluating the quality of communication between physicians and cancer patients and their family caregivers in China, this study translated and culturally adapted the Quality of Communication questionnaires for cancer patients (QOC-P) and their family caregivers (QOC-F) for use in the Chinese context and evaluated their psychometric properties. METHODS: The QOC-P and QOC-F were translated following an adapted version of Brislin's translation model and culturally adapted according to a Delphi expert panel. We pretested and refined the Chinese versions of the QOC-P and QOC-F among 16 dyads of patients and their family caregivers. Subsequently, we administered the questionnaires to 228 dyads of patients and their family caregivers who were recruited from six tertiary hospitals. The content validity, construct validity, convergent validity, and reliability of the QOC-P and QOC-F were examined. RESULTS: Through exploratory factor analysis, The QOC-P and QOC-F were divided into two dimensions: general communication and end-of-life communication. The Cronbach's coefficients ranged from 0.905 to 0.907 for the two subscales of the QOC-P and from 0.908 to 0.953 for the two subscales of the QOC-F. The two-week test-retest reliability was acceptable for both the QOC-P and QOC-F, with intraclass correlation coefficients of 0.993 and 0.991, respectively. The scale content validity index (QOC-P: 0.857, QOC-F: 1.0) and split-half reliability (QOC-P: 0.833, QOC-F: 0.935) were satisfactory. There was a negative correlation with anxiety and depression for both the QOC-P (r = -0.233 & -0.241, p < 0.001) and QOC-F (r = -0.464 & -0.420, p<0.001). The QOC-P showed a negative correlation with decision regret (r = -0.445, p<0.001) and a positive correlation with shared decision-making (r = 0.525, p<0.001), as hypothesized. CONCLUSION: The QOC-P and QOC-F show acceptable psychometric properties for evaluating the quality of communication between physicians and cancer patients and their family caregivers in both clinical and research contexts. Future studies should use more diverse and inclusive samples to test the structure of the Chinese version of the QOC-P and QOC-F with confirmatory factor analysis.

Experimental study on the effect of luteolin on the proliferation, apoptosis and expression of inflammation-related mediators in lipopolysaccharide-induced keratinocytes.

OBJECTIVE: This study aimed at exploring the effects of luteolin on psoriasis-like cell model proliferation, apoptosis regulation and the expression of inflammation-related mediators. METHODS: A Cell Counting Kit-8 (CCK-8) assay was used to determine the survival rate of human immortalized keratinocytes (HaCaT cells) and normal human epidermal keratinocytes (NHEK cells) following stimulation with luteolin and lipopolysaccharide (LPS). Western blot and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis were used to detect the protein and mRNA expressions of nuclear factor (NF)-κB p65 and interleukin (IL)-6 after LPS stimulation. Then a luteolin stimulation protocol (10 µmol/L, 24 h) was determined and a reasonable LPS stimulation concentration (20 µg/mL, 24 h) was chosen to establish the psoriasis cell model. Keratinocytes in luteolin pre-treatment and control groups were stimulated with 20 µg/mL LPS for 24 h, and the expressions of NF-κB p65 and IL-6 were detected by western blot and RT-qPCR. The apoptosis of HaCaT cells was detected by flow cytometry, and the enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of psoriasis-related inflammatory factors. RESULTS: CCK-8 assay indicated that luteolin inhibited the proliferation of keratinocytes. LPS stimulated the proliferation of keratinocytes and upregulated the expression of NF-κB p65 and IL-6 in a concentration-dependent manner, and induced psoriasis-like changes. Furthermore, the protein and mRNA expression levels of NF-κB p65 and IL-6 were decreased in the luteolin pre-stimulation group (p < 0.05). Treatment with luteolin downregulated the expression of the LPS-induced inflammatory mediators in keratinocytes (p < 0.05). The flow cytometry results showed that luteolin induced HaCaT cells apoptosis. Finally, ELISA results demonstrated that luteolin inhibited the release of the IL-17, IL-23 and tumor necrosis factor α (TNF-α) in the pre-stimulation group (p < 0.05). CONCLUSION: This study confirmed that luteolin can effectively relieve inflammatory mediators in LPS-induced keratinocyte models of psoriasis, which suggested the potential of luteolin in treating psoriasis.

Intimate Partner Violence Screening Instruments: A Protocol for a COSMIN-Based Systematic Review.

Intimate partner violence (IPV) is a major public health problem resulting in a significant impediment to equal participation, quality of life, and personal, social, and economic development. At present, a variety of screening instruments for IPV have emerged in developed countries, and some of them have been adapted to the language and culture of different countries, such as Hurt, Insult, Threaten, Scream (HITS) and the Abuse Assessment Screen (AAS). The selection of the most appropriate IPV screening instrument for the target population and context from among those instruments has become difficult for researchers when intending to start screening. Therefore, a systemic review of IPV screening instruments is needed. This protocol describes a COSMIN-based systematic review of the measurement properties of these instruments. The aims of the systematic review are to (1) evaluate the methodological quality of studies on the measurement properties including the validity, reliability, and internal consistency of these IPV screening instruments, and (2) provide suggestions for relevant researchers in their local context for using the IPV screening instruments.

Association between spiritual care competency and perceived professional benefit among nurses: A cross-sectional study.

AIMS: This study aimed to investigate the status quo of nurses' spiritual care competency and their relationship with perceived professional benefit. BACKGROUND: Spiritual care has always been considered a vitally important part of holistic nursing. Understanding the spiritual care competency of nurses during the COVID-19 pandemic can help nursing managers understand the weak links in spiritual care practice and improve the quality of nursing service. As a positive emotional experience and cognitive evaluation of the profession, perceived professional benefit can serve to adjust work pressure, relieve job burnout and promote an individual's overall growth. However, the relationship between perceived professional benefit among nurses and spiritual care competency remains unclear. METHODS: A total of 372 nurses were recruited from 15 separate Chinese hospitals. An online questionnaire was used to assess nurses' sociodemographic, spiritual care competency and perceived professional benefit. Statistical analyses were performed using Pearson's correlation analysis, t test, analysis of variance (ANOVA) and multiple stepwise linear regression analysis. RESULTS: The total mean score of spiritual care competency (99.43 ± 21.10) among nurses was found to be moderate. Nurses' spiritual care competency was positively correlated with perceived professional benefit (P < .01). The multiple stepwise linear regression model (n = 372) had an explained variance (R2 = 0.218) and showed that perceived professional benefit and the manner of receiving spiritual training were the main influencing factors of nurses' spiritual care competency (P < .001). CONCLUSION: The study findings indicated that nurses need to improve their spiritual care competency by improving their perceived professional benefit. IMPLICATION FOR NURSING MANAGERS: Our study evaluated the spiritual care competency of nurses and explored the correlation between perceived professional benefit and spiritual care competency among nurses. The results of this study can help nursing managers to carry out relevant interventions, thus improving nurses' spiritual care competency and optimizing the quality of nursing.

[Analysis of genetic variant in a case of sporadic neurofibromatosis type I with alopecia areata and vitiligo].

OBJECTIVE: To explore the genetic basis for a patient with clinically suspected neurofibromatosis type I, alopecia areata and vitiligo. METHODS: Variant of the NF1 gene was detected by chip capture and high-throughput sequencing. Candidate variant was verified by Sanger sequencing of the family trio. RESULTS: The patient was found to harbor a novel missense c.1885G>A (p.Gly629Arg) variant of the NF1 gene, for which neither parent was carrier. The variant was not recorded in the public database. Based on the guidelines for genetic variation of the American College of Medical Genetics and Genomics, the c.1885G>A missense variant was predicted to be pathogenic (PS1+PS2+PM2+PP3+PP4). CONCLUSION: The c.1885G>A missense variant probably underlay the disease in this child. Above finding has enriched the spectrum of the NF1 gene variants.

Unveiling the Metabolic Profile of First-Episode Drug-Naïve Schizophrenia Patients: Baseline Characteristics of a Longitudinal Study Among Han Chinese.

Objective: Metabolic and other medical conditions are frequently comorbid with schizophrenia. As they might be the side-effects of antipsychotic treatment, studying first-episode drug-naïve schizophrenia (FDSZ) provides a unique opportunity to investigate a direct pathogenic link between metabolic changes and schizophrenia. Here, we presented the methods and baseline unique metabolic profile of FDSZ patients without medical comorbidities unveiling subthreshold indices of metabolic disturbances. Method: Drug-naïve individuals diagnosed with schizophrenia but without any previous medical conditions were invited to participate in the study. Participants were submitted to structured psychiatric and cognitive assessments, laboratory and neuroimaging tests. Subjects will be followed after antipsychotic treatment at 6, 24 and 48 weeks. Results: During an 8-month-period, out of 103 patients presenting with first episode psychosis, 67 subjects (43.3% men, 56.7% women) were enrolled in the study. They had a mean ± SD age of 32.1 ± 8.7 years, with a mean BMI of 21.1 kg/m2 and 11.3 ± 3.6 years of schooling. Less than 1/3 reported a family history of mental illness. Upon laboratory assessment, 10.4%, 7.5%, and 11.9% of patients were identified with hyperhomocysteinemia, hypertriglyceridemia and hyperprolactinemia, respectively, with percentages of women relatively higher than men except for hypertriglyceridemia. Conclusions: First episode schizophrenia patients, especially women, present subclinical metabolic abnormalities, independent of antipsychotic treatment.

Subjective Family Socioeconomic Status and Peer Relationships: Mediating Roles of Self-Esteem and Perceived Stress.

This study explored the relationships between subjective family socioeconomic status (FSES), self-esteem, perceived stress, and perceived peer relationships among Chinese adolescents. A total of 1,353 adolescents (age range: 15-19 years) were asked to complete a questionnaire. Mediation analysis revealed that subjective FSES influenced perceived peer relationships in three ways: first, through the mediating effect of perceived stress; second, through the mediating effect of self-esteem; and third, through the serial mediating effects of perceived stress and self-esteem. The results remained significant after controlling for parental education. In addition, a contrast analysis showed no significant differences in the mediating effects of self-esteem and perceived stress. Thus, we suggest that steps should be taken to improve adolescents' self-esteem and reduce their stress through training interventions and preventive measures, to help them improve their perceived peer relationships and reduce adverse effects associated with low subjective FSES.

Cardamonin as a potential treatment for melanoma induces human melanoma cell apoptosis.

2',4'-dihydroxy-6'-methoxychalcone (cardamonin) is a natural compound with anti-proliferative effects on several cancer types including nasopharyngeal carcinoma. The effects of cardamonin on melanoma cells are unknown. The present study investigated the anti-proliferative effect of cardamonin on human melanoma cell lines (M14 and A375), and the underlying apoptosis inducing mechanisms. MTS assay showed that cardamonin inhibited M14 cells viability, and a reduction of the M14 cell density was also observed. Flow cytometry showed that cardamonin induced M14 cells apoptosis in a dose-dependent manner. Western blot analysis showed protein expression in M14 and A375; the pro-apoptotic protein BAX was upregulated, while the anti-apoptotic protein B-cell lymphoma-2 was downregulated. The protein expression of cleaved caspase-8, -9 and cleaved poly (ADP-ribose) polymerase was increased, whereas P65 was decreased. Furthermore, cardamonin inhibited M14 cell migration. These findings suggest that cardamonin may be a novel anticancer treatment for human melanoma.

High-precision temperature sensor based on weak measurement.

High-precision temperature sensor is demonstrated based on weak measurement using spectrum domain analysis. By introducing an extra phase to the postselection, the operating temperature range and temperature precision can be conveniently modulated. Spectral shifts resulted from temperature variation are robust to practical imperfections. The precision of 2.4 × 10-6°C can be achieved by a currently available spectrometer. The maximum operating range is associated with the nematic temperature range of nematic liquid crystals (NLCs) sample. Moreover, the temperature sensitivity of 16.16 nm/°C is obtained experimentally in different linear operating intervals.

Hair regrowth in alopecia areata patients following Stem Cell Educator therapy.

BACKGROUND: Alopecia areata (AA) is one of the most common autoimmune diseases and targets the hair follicles, with high impact on the quality of life and self-esteem of patients due to hair loss. Clinical management and outcomes are challenged by current limited immunosuppressive and immunomodulating regimens. METHODS: We have developed a Stem Cell Educator therapy in which a patient's blood is circulated through a closed-loop system that separates mononuclear cells from the whole blood, allows the cells to briefly interact with adherent human cord blood-derived multipotent stem cells (CB-SC), and returns the "educated" autologous cells to the patient's circulation. In an open-label, phase 1/phase 2 study, patients (N = 9) with severe AA received one treatment with the Stem Cell Educator therapy. The median age was 20 years (median alopecic duration, 5 years). RESULTS: Clinical data demonstrated that patients with severe AA achieved improved hair regrowth and quality of life after receiving Stem Cell Educator therapy. Flow cytometry revealed the up-regulation of Th2 cytokines and restoration of balancing Th1/Th2/Th3 cytokine production in the peripheral blood of AA subjects. Immunohistochemistry indicated the formation of a "ring of transforming growth factor beta 1 (TGF-ß1)" around the hair follicles, leading to the restoration of immune privilege of hair follicles and the protection of newly generated hair follicles against autoimmune destruction. Mechanistic studies revealed that co-culture with CB-SC may up-regulate the expression of coinhibitory molecules B and T lymphocyte attenuator (BTLA) and programmed death-1 receptor (PD-1) on CD8ß(+)NKG2D(+) effector T cells and suppress their proliferation via herpesvirus entry mediator (HVEM) ligands and programmed death-1 ligand (PD-L1) on CB-SCs. CONCLUSIONS: Current clinical data demonstrated the safety and efficacy of the Stem Cell Educator therapy for the treatment of AA. This innovative approach produced lasting improvement in hair regrowth in subjects with moderate or severe AA. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01673789, 21 August 2012.

AIM: To investigate the intervenient effect of compound traditional Chinese medicine on dendritic cells (DCs) in peripheral blood in vitro. METHODS: DCs in peripheral blood were cultured for five days with medium which had GM-CSF and IL-4. The compound traditional Chinese medicine were added into the medium and the cells were collected on the 5th day. Surface markers of CD83 and CD86 in DCs were analyzed by flow cytometry. The capability of DC to stimulate the proliferation of T lymphocytes was evaluated by allogeneic mixed lymphocyte reaction. The content of IL-12 in cell culture supernatant was detected by ELISA. RESULTS: The expression of CD83 and CD86 was increased significantly(P<0.001) after the addition of the compound traditional Chinese medicine. The capability of DC to stimulate the proliferation of T lymphocytes was increased evidently (P<0.05). However the production of IL-12 was decreased obviously(P<0.001). CONCLUSION: The compound traditional Chinese medicine has immunoregulation of DC, It can enhance the presenting capability of antigen in DCs and inhibit the production of IL-12.

[The effects of pcDNA3.1-IL-15 transfection on the surface molecules and immune function of murine bone marrow-derived dendritic cells].

AIM: To explore the effects of pcDNA3.1-IL-15 transfected on co-stimulatory molecule expression and immune function on murine bone marrow-derived dendritic cells (DCs). METHODS: Recombinant plasmid pcDNA3.1-IL-15 was constructed and used to transfect DCs. The expression of CD40, CD80 and CD86 on the transfected DCs was analyzed by flow cytometry. Murine splenocytes were stimulated with the transfected DCs. CD4+ and CD8+ T cell subsets in the splenocytes were analyzed by flow cytometry. The proliferation of splenocytes was detected by MTT colorimetry. The IFN-gamma in the culture supernatant of the splenocytes was detected by ELISA. RESULTS: pcDNA3.1-IL-15-transfected DCs expressed higher level of CD40, CD80 and CD86, and induced proliferation of CD4+ T cells and CD8+ T cells in the splenocytes. But the ratio of CD4+/CD8+ T cells was lower than that in the spleen cells stimulated by untransfected DCs or DCs transfected with pcDNA3.1. CONCLUSION: pcDNA3.1-IL-15 can improve the expression of co-stimulatory molecules on DCs and enhance their immune function.
