Purpose: This study aimed to develop and evaluate the effectiveness of the Trauma-nursing Education and Skill Support (TESS) program based on the ADDIE model (Analysis, Design, Development, Implementation, Evaluation model). The program was designed to enhance trauma nurses’ clinical competencies, including trauma-related knowledge, self-efficacy, and problem-solving ability, through the integration of theoretical education and simulation-based practice. Methods: A quasi-experimental study using a non-equivalent control group pretest–posttest design was conducted. Participants included 108 trauma nurses from regional trauma centers, military trauma centers, and emergency care facilities, who were assigned to an experimental group (n=52) or a control group (n=56). The TESS program consisted of a 2-day, 14-hour blended-learning course that included eight lecture sessions and four simulation-based practice stations. Data were collected at baseline, immediately after the intervention, and at 6 months using validated instruments measuring trauma-related knowledge, self-efficacy, and problem-solving ability. Two-way repeated-measures analysis of variance was used for data analysis. Results: The experimental group demonstrated significant improvements in trauma-related knowledge, self-efficacy, and problem-solving ability compared with baseline (all p<.001). These improvements were sustained at 6 months, although trauma-related knowledge scores showed a slight decline compared with immediate posttest levels. Between-group analyses confirmed significant group-by-time interaction effects for all outcomes: trauma-related knowledge (η2=0.12, p<.001), self-efficacy (η2=0.09, p=.002), and problem-solving ability (η2=0.08, p=.003). Conclusion The TESS program effectively enhanced trauma nurses’ trauma-related knowledge, self-efficacy, and problem-solving ability, with effects sustained for up to 6 months. Incorporating blended learning and simulation-based training into standardized trauma nursing education may strengthen clinical competencies and ultimately contribute to improved patient outcomes.

OBJECTIVE: Varied acupoint selections represent a potential cause of the uncertainty surrounding the efficacy of acupuncture for knee osteoarthritis (OA). Skin temperature, a guiding factor for acupoint selection, may help to address this issue. This study explored thermal sensitization of acupoints used for the treatment of knee OA. METHODS: This cross-sectional case-control study enrolled cases aged 45-75 years with symptomatic knee OA and age- and gender-matched non-knee OA controls in a 1:1 ratio. All participants underwent infrared thermographic imaging. The primary outcome was the relative skin temperature of acupoint (STA), and the secondary outcome was the absolute STA of 11 acupoints. The Z test was used to compare the relative and absolute STAs between the groups. Principal component analysis was used to extract the common factors (CFs, acupoint cluster) in the STAs. A general linear model was used to identify factors affecting the STA in the knee OA cases. For the group comparisons of relative STA, P < 0.0045 (adjusted for 11 acupoints through Bonferroni correction) was considered to indicate statistical significance. For other analyses, P < 0.05 was used as the threshold for statistical significance. RESULTS: The analysis included 308 participants, consisting of 151 cases (mean age: [64.58 ± 6.67] years; male: 25.83%; mean body mass index: [25.70 ± 3.16] kg/m²) and 157 controls (mean age: [63.37 ± 5.96] years; male: 26.11%; mean body mass index: [24.47 ± 2.84] kg/m²). The relative STAs of ST34 (P = 0.0001), EX-LE2 (P < 0.0001), EX-LE5 (P = 0.0006), SP10 (P < 0.0001), BL40 (P = 0.0012) and GB39 (P = 0.0037) were higher in the knee OA group. No difference was found in the STAs of ST35, ST36, SP9, GB33 and GB34. Four CFs were identified for relative STA in both groups. The acupoints within each CF were consistent between the groups. The mean values of the relative STAs across each CF were higher in the knee OA group. In the knee OA cases, no factors were observed to affect the relative STA, while age and gender were found to affect the absolute STA. CONCLUSION Among patients with knee OA, thermal sensitization occurs in the acupoints of the lower extremity, exhibiting localized and regional thermal consistencies. The thermally sensitized acupoints that we identified in this study, ST34, SP10, EX-LE2, EX-LE5, GB39 and BL40, may be good choices for the acupuncture treatment of knee OA.

Acupuncture is an ancient treatment method used in traditional Chinese medicine and has been popularized worldwide. Over the past decade, there has been an increase in the amount of acupuncture research, mostly comprised of randomized controlled trials (RCTs) that aimed to answer the question on the efficacy of acupuncture. However, poor methodology and low replicability in these acupuncture RCTs have resulted in uncertainty about the efficacy of acupuncture. In this review, current advancements and challenges in acupuncture RCTs, regarding the methodological aspects of randomization, blinding, sham acupuncture and quality of reporting, were discussed. While there have been advancements in various aspects, current acupuncture RCTs still face pressing issues such as inadequate randomization and blinding, unviable sham acupuncture controls, and poor reporting quality. Given these limitations, this review seeks to identify the methodological problems that are responsible for these problems and to suggest solutions that could help to overcome them so as to improve the quality of future studies evaluating the efficacy of acupuncture.

Objective To investigate the protective effect of Gynostemma pentaphyllum on memory of individuals rapidly ascending to high altitudes.Methods Twenty-one healthy subjects were randomly divided into a G.pentaphyllum food group(n=12)and a control group(n=9).The first group consumed G.pentaphyllum food for seven consecutive days while the control group received placebos.Both groups ascended from the plains to an altitude of 3600 m.Memory function was assessed using the matching memory and sequential memory tests of a cognitive evaluation system on day 1 and day 7 on the plains,and at 24 and 48 h after ascending to the high altitude.Scores of acute mountain sickness symptoms were also recorded.Results After 24 h of stay at the high altitude,the score of headache of the G.pentaphyllum food group was significantly lower than that of the control group(P＜0.05).Cognitive test results showed that the matching memory accuracy and sequential memory accuracy of the control group at 24 and 48 h were significantly lower than those on the plains(P＜0.05).In contrast,the G.pentaphyllum food group performed significantly better than the control group in these metrics(P＜0.05).Conclusion Regular consumption of G.pentaphyllum food can effectively alleviate headache symptoms in individuals rapidly ascending to high altitudes and mitigate the decline in working memory,short-term memory,and memory spans caused by acute hypoxic exposure.

Brasilicardin A, a diterpene glycoside isolated from pathogenic actinomycete Nocardia brasiliensis IFM 0406, has become a novel immunosuppressant candidate due to its significant immunosuppressive activity, low toxicity and unique mechanism of action. However, brasilicardin A and its analogues have become a research hotspot to the development of this promising immunosuppressant because of the low-yield production in the natural pathogenic producer and the synthetically challenging skeleton. According to the reported biosynthetic pathway of brasilicardin A, the function of involved diterpene synthase was analyzed by bioinformatics. Then the genes bra1-5 that synthesize the brasilicardin A skeleton were directionally amplified from the pathogenic strain N. brasiliensis IFM 0406, and heterologous expression was achieved successfully in Streptomyces albus R1. The compounds were isolated and purified by using various column chromatographies including silica gel column chromatography and semi-preparative HPLC. Six new brasilicardins were established and named brasilicardin H-M. The activity of brasilicardins was screened using lipopolysaccharide (LPS)-activated mouse primary macrophage inflammation model. Brasilicardin H-M exhibited good inhibitory activity on nitric oxide (NO) release with IC₅₀ values of 28.24 ± 3.70, 37.44 ± 2.00, 39.85 ± 4.02, 26.77 ± 4.40, 65.25 ± 1.48 and 15.24 ± 2.72 μmol·L^-1, respectively (indomethacin as the positive control with IC₅₀ value of 34.28 ± 4.10 μmol·L^-1). The results indicated that six compounds had potential anti-inflammatory activity. This study laid a foundation for the elucidation of the brasilicardin A biosynthetic pathway and evaluation of the structure-activity relationship as well as new drug developments.

Non-alcoholic fatty liver disease (NAFLD) incidence is rapidly increasing and become the most common chronic liver disease globally. NAFLD also possesses a risk of developing cardiovascular, kidney, and other diseases. To date, NAFLD still faces difficulties in early diagnosis and treatment options. Thus, early detection, prevention, optimally individualized treatment selections, and prediction of prognosis all are the keys in clinical NAFLD control. Although there are assessment tools available for NAFLD severity appraisal using different clinical parameters, it becomes a hot topic of research in the field for how to optimize non-invasive assessment methodologies. Artificial intelligence (AI) and machine learning are increasingly being used in healthcare, especially in assessment and analysis of chronic liver disease, including NAFLD. This review summarized and discussed the most recent progress of AI and machine learning in differential diagnosis of NAFLD and evaluation of NAFLD severity, in order to provide treatment selections, i.e., the novel AI diagnosis models based on the electronic health records and laboratory tests, ultrasound and radiographic imaging, and liver histopathology data. The therapeutic models discussed the personalized lifestyle changes and NAFLD drug development. The NAFLD prognosis model reviewed and predicted how NAFLD-changed liver metabolisms affect prognosis of patients. This review also speculated future prospective research hot spots and development in the filed for how to utilize the existing AI models to distinguish NAFLD and non-alcoholic steatohepatitis (NASH) and assess NAFLD fibrosis status.

Objective: The relationship between outdoor temperature and blood pressure (BP) has been inconclusive. We analyzed data from a prospective cohort study in northwestern China to investigate the effect of outdoor temperature on BP and effect modification by season. Methods: A total of 32,710 individuals who participated in both the baseline survey and the first follow-up in 2011-2015 were included in the study. A linear mixed-effect model and generalized additive mixed model (GAMM) were applied to estimate the association between outdoor temperature and BP after adjusting for confounding variables. Results: The mean differences in systolic blood pressure (SBP) and diastolic blood pressure (DBP) between summer and winter were 3.5 mmHg and 2.75 mmHg, respectively. After adjusting for individual characteristics, meteorological factors and air pollutants, a significant increase in SBP and DBP was observed for lag 06 day and lag 04 day, a 0.28 mmHg (95% Conclusions This study demonstrated a significant negative association between outdoor temperature and BP in a high-altitude environment of northwest China. Moreover, BP showed a significant seasonal variation. The association between BP and temperature differed by season and individuals' demographic characteristics (age, gender, BMI), unhealthy behaviors (smoking and alcohol consumption), and chronic disease status (CVDs, hypertension, and diabetes).

OBJECTIVE: To test the reliability and validity of the Chinese version of parenting sense of competence scale (PSOC) in Chinese mothers of preschool children, and to explore the perception of preschool children's mothers on their own parenting skills and their comfort of being a parent in Yanqing District of Beijing. METHODS: A cross-sectional survey was conducted using a convenience sample in 1 384 preschool children's mothers in Yanqing District of Beijing. SPSS 21.0 and Mplus 7.4 software were used for statistical analysis to test the structural validity, criterion related validity, internal consistency and split half reliability of the scale, and to analyze the score of the scale and its influencing factors. RESULTS: The PSOC had good reliability and validity. Exploratory factor analysis showed that each item of the PSOC had more than 0.4 factor loading in efficacy factor or satisfaction factor, and there was no double load phenomenon. Confirmatory factor analysis showed that the factor loadings ranged from 0.212 to 0.843 in efficacy factor and satisfaction factor, respectively. The goodness of fit test showed that all the fitting indexes were within the acceptable range, and the correlation between the effectiveness subscale and the satisfaction subscale was high. The Cronbach's α coefficient of the whole scale, the efficacy subscale and the satisfaction subscale were 0.872, 0.802, and 0.874, respectively. The Spearman-Brown coefficient of PSOC was 0.851. The average score of the whole scale, the efficacy subscale, and the satisfaction subscale were 72.33±11.31, 35.54±5.91, and 36.79±7.11, respectively, and the score of parenting competence in Chinese mothers of preschool children was influenced by the mother's educational level and the annual income of her family. CONCLUSION The PSOC has satisfactory reliability and validity in Chinese mothers of preschool children. It can be used as an evaluation instrument for measuring the parenting competency, self perceived efficacy and satisfaction in the mainland Chinese mothers of preschool children. The competency of preschool children's mothers in Yanqing District of Beijing is very good, which may be related to the higher education level of the mothers and the higher annual income of their families in this study.

Knee osteoarthritis is the most common type of arthritis, which is manifested by the deformation and degeneration of articular cartilage and the discomfort of patients with joint pain, which affects the quality of life of patients and aggravates the medical burden of society. The pathogenesis of knee osteoarthritis is very complex. This paper reviews the inflammatory factors and signal pathways involved in knee osteoarthritis. It is found that most of the inflammatory factors involved are interleukin, such as IL-1 β, IL-6, IL-15, IL-17, IL-18, and tumor necrosis factors, such as TNF-α. These inflammatory factors aggravate knee osteoarthritisby activating corresponding pathways and promoting the release of inflammatory mediators. The inflammatory signaling pathways involved in knee osteoarthritis are complex. Notch pathway, Wnt pathway, SDF-1 / CXCR4 pathway, TLRs pathway, MAPKs pathway, hippo Yap pathway, OPG-RANK-RANKL pathway and TGF-β pathway are all involved in the regulation of knee osteoarthritis, and the pathways related to inflammatory mechanism are mainly MAPKs pathway and TLRs pathway. Different signaling pathways can cause the destruction of articular cartilage, promote the apoptosis of chondrocytes, and finally lead to the further imbalance of homeostasis in the knee joint. At the same time, the activation of signal pathway can promote the release of inflammatory factors, so under the cascade reaction of inflammatory factors and signal pathway, knee osteoarthritis is aggravating.
