[Analysis of potential pharmacodynamic material basis of Euonymus alatus in treatment of nephritis based on integrated chemomics and network biology].

This paper was aimed to explore the potential pharmacodynamics effect of Euonymus alatus in the treatment of nephritis based on integrated chemomics and network biology. The chemical constituent database of E. alatus was constructed by consulting litera-ture and using online database. The chemical constituents were identified by UPLC-Q-TOF/HRMS~E and UNIFI software. On this basis, a series of comparisons, molecular docking studies and in-depth analysis of the chemical constituents and nephritis disease targets were carried out with use of network biology method, and the potential pharmacodynamic effect of E. alatus for the treatment of nephritis was investigated by reviewing the existing. In this study, 62 chemical constituents were collected in the database of chemical consti-tuents of E. alatus, and 24 chemical constituents were identified by mass spectrum. Subsequently, based on the network biology me-thod, 22 important chemical constituents and 5 key targets were obtained by reverse screening. Molecular docking study showed that a total of 11 chemical constituents such as quercetin, kaempferol, and catechinmay be the potential material basis for E. alatus in the treatment of nephritis. Starting with chemomics and using the technology of network biology, we established a network interaction model between drug components and disease targets in this study. Through the interaction between targets in complex networks, we can find the key targets easily and quickly. By docking the key targets with small drug molecules, we can screen out the potential pharmacodynamic components, providing a reference for the follow-up study of active ingredients.

Cognitive engagement of nursing undergraduates in blended learning: A parallel mixed method study.

BACKGROUND: Blended learning is being integrated into undergraduate nursing education at all levels and from all directions. Cognitive engagement is not only an embodiment and guarantee of students' engagement into the curriculum from a cognitive level, deep engagement and high-level thinking, but also an important indicator of whether students are effectively engaged in the blended learning curricula. However, no studies have been seen to investigate the cognitive engagement of nursing undergraduates in the blended learning curricula and its influential factors. OBJECTIVES: To explore nursing undergraduates' cognitive engagement during the blended learning curricula and its influential factors. DESIGN: A convergent parallel mixed-methods was used. Data were collected between November 2021 and May 2022, inclusive. SETTINGS AND PARTICIPANTS: The study was carried out in the nursing school at a university in China. Participants including students undertaking entry to the blended learning curricula. METHODS: In the quantitative component (n = 142), participants' cognitive engagement was investigated and factors associated with it were examined using univariate analysis, correlation analysis and multiple regression analysis. During this period, personal, semi-structured interviews were conducted with a subset of these participants (n = 15) to understand participants' cognitive engagement experiences. RESULTS: The cognitive engagement of nursing undergraduates was at a moderate level and the cognitive engagement experiences were reflected in the four themes of Reconstitution, Connection, Elaboration and Retention. The influential factors of cognitive engagement were learning activities (ß = 0.226, p = 0.004), autonomy (ß = 0.158, p = 0.047), academic self-efficacy (ß = 0.311, p < 0.001, ß = 0.271, p < 0.001) and social interaction (ß = 0.358, p < 0.001). CONCLUSIONS: The cognitive engagement of nursing undergraduates in the blended learning curricula needs to be improved. To maximize promote cognitive engagement of nursing undergraduates in the blended learning curricula, educators should design diverse learning activities, engage in high quality social interactions with students, and maximize students' autonomy and self-efficacy.

The effectiveness of auricular acupressure on pain management during labor: A systematic review and meta-analysis of randomized controlled trials.

AIM: This meta-analysis aimed to systematically evaluate the effectiveness of auricular acupressure on pain management during labor. METHODS: Six English and three Chinese electronic databases were comprehensively searched from inception to 6 November 2021. The PRISMA checklist was followed. The methodological quality of the included studies was assessed with the Cochrane Collaboration Bias Risk Assessment Tool. The meta-analysis was performed using Review Manager 5.3 software. Heterogeneity between studies was calculated using I2 . RESULTS: Five studies comprising 312 participants were included. The labor pain scores of the auricular acupressure group were significantly lower than those of the usual care group at cervix dilations of 6, 8, and 10 cm, with mean differences (95% confidence intervals) of -1.05 (-1.41, -0.69), -1.44 (-2.07, -0.82), and -1.96 (-3.30, -0.61), respectively. Auricular acupressure can thus effectively improve the labor pain perception at cervix dilations of 6, 8, and 10 cm. Moreover, auricular acupressure shortened the active phase, and had the trend of shortening the second and third stages of labor. There was no evidence that auricular acupressure had an effect on the rate of cesarean section or the 1 and 5 min Apgar scores. CONCLUSION: Effective labor pain relief, better labor pain perception, and the lack of adverse effects support the use of auricular acupressure. More high-quality and rigorous trials are needed to verify our findings before we can make strong recommendations.

Expression and significance of TWIST basic helix-loop-helix protein over-expression in gastric cancer.

AIMS: TWIST protein has been implicated in neoplastic transformation and development of some cancers. In this study, we aimed to investigate the expression of TWIST in gastric cancer and its clinical significance. METHODS: A total of 76 cases of archival gastric cancer tissues were immunohistochemically evaluated for TWIST expression, and its expression was correlated with clinicopathological parameters. Semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect the mRNA of TWIST in four gastric cancer cell lines and a normal immortalised gastric epithelial cell line (GES-1). The expression of TWIST protein in these cell lines and 14 pairs of fresh gastric carcinoma and adjacent normal tissue samples was detected by Western blotting. RESULTS: TWIST expression increased in diffuse-type gastric carcinoma compared with intestinal-type gastric carcinoma (26/42, 61.9% versus 9/34, 26.5%, p<0.05). TWIST expression was significantly increased in 35 (46.1%) of the 76 cancers and correlated with lymph node metastasis (node positive rate 60.4%; node negative rate 21.4%; p<0.05). The expression of TWIST protein was higher in 9/14 (64.3%) fresh cancer tissues compared with adjacent normal tissues. The expression of mRNA and protein of TWIST in gastric cancer cell lines was up-regulated compared with that in GES-1. CONCLUSIONS: TWIST was highly expressed in gastric cancer. Its up-regulation was associated with the neoplastic transformation and subsequent development of gastric cancer. Therefore, TWIST may be a useful prognostic marker and target for gastric cancer therapy.

A case of perforating injury of eyeball and traumatic cataract caused by acupuncture.

Perforating globe injury is the leading cause of monocular blindness and vision loss. A 58-year-old male was injured by acupuncture needle during acupuncture treatment for his cerebral infarction. To the best of our knowledge, this is the first case report of perforating injury of the eyeball and traumatic cataract caused by acupuncture. The patient was hospitalized due to diagnosis of perforating ocular injury, traumatic cataract, and corneal and iris perforating injury. Moreover, he had to accept treatments of phacoemulsification, anterior vitrectomy along with intraocular lens implantation in the sulcus to improve his visual acuity. As acupuncture therapy has been widely performed for various diseases and achieved highly approval, the aim of this report is to remind acupuncturists operating accurately to avoid unnecessary injury during the treatment process, or the cure can also become the weapon.
