Gain deeper insights into traditional Chinese medicines using multidimensional chromatography combined with chemometric approaches / 中草药·英文版

Traditional Chinese medicines (TCMs) possess a rich historical background, unique theoretical framework, remarkable therapeutic efficacy, and abundant resources. However, the modernization and internationalization of TCMs have faced significant obstacles due to their diverse ingredients and unknown mechanisms. To gain deeper insights into the phytochemicals and ensure the quality control of TCMs, there is an urgent need to enhance analytical techniques. Currently, two-dimensional (2D) chromatography, which incorporates two independent separation mechanisms, demonstrates superior separation capabilities compared to the traditional one-dimensional (1D) separation system when analyzing TCMs samples. Over the past decade, new techniques have been continuously developed to gain actionable insights from complex samples. This review presents the recent advancements in the application of multidimensional chromatography for the quality evaluation of TCMs, encompassing 2D-gas chromatography (GC), 2D-liquid chromatography (LC), as well as emerging three-dimensional (3D)-GC, 3D-LC, and their associated data-processing approaches. These studies highlight the promising potential of multidimensional chromatographic separation for future phytochemical analysis. Nevertheless, the increased separation capability has resulted in higher-order data sets and greater demands for data-processing tools. Considering that multidimensional chromatography is still a relatively nascent research field, further hardware enhancements and the implementation of chemometric methods are necessary to foster its robust development.

The mediation role of self-esteem between workplace bullying and mental health among nurses:the moderating effect of self-efficacy / 中华行为医学与脑科学杂志

Objective To investigate the impact of workplace bullying,general self?efficacy,self?es?teem on mental health of nurses. Methods With random sampling,450 nurses from six hospitals in Nanning of Guangxi were selected to complete questionnaire survey. Results 34.7% of nurses were reported to have been subjected to bullying at their workplace. Workplace bullying(23.78±6.94) showed significantly nega?tive relationship with mental health(36.63±4.53)( r=-0.32, P<0.01),while general self?efficacy(26.86± 4.82) and self?esteem(30.62±4.08) showed significantly positive correlations with mental health( r=0.45, 0.44, P<0.01). Workplace bullying had a significantly negative effect on mental health ( β=-0.25, P<0.01) ,and the relationship was affected by general self?efficacy and self?esteem. Conclusion Workplace bullying can influent nurses' mental health through self?esteem and the relationship is moderated by general self?efficacy.
