In smart classrooms, conducting multi-face expression recognition based on existing hardware devices to assessstudents’ group emotions can provide educators with more comprehensive and intuitive classroom effect analysis,thereby continuouslypromotingthe improvementof teaching ***,most existingmulti-face expressionrecognition methods adopt a multi-stage approach, with an overall complex process, poor real-time performance,and insufficient generalization ability. In addition, the existing facial expression datasets are mostly single faceimages, which are of low quality and lack specificity, also restricting the development of this research. This paperaims to propose an end-to-end high-performance multi-face expression recognition algorithm model suitable forsmart classrooms, construct a high-quality multi-face expression dataset to support algorithm research, and applythe model to group emotion assessment to expand its application value. To this end, we propose an end-to-endmulti-face expression recognition algorithm model for smart classrooms (E2E-MFERC). In order to provide highqualityand highly targeted data support for model research, we constructed a multi-face expression dataset inreal classrooms (MFED), containing 2,385 images and a total of 18,712 expression labels, collected from smartclassrooms. In constructing E2E-MFERC, by introducing Re-parameterization visual geometry group (RepVGG)block and symmetric positive definite convolution (SPD-Conv) modules to enhance representational capability;combined with the cross stage partial network fusion module optimized by attention mechanism (C2f_Attention),it strengthens the ability to extract key information;adopts asymptotic feature pyramid network (AFPN) featurefusion tailored to classroomscenes and optimizes the head prediction output size;achieves high-performance endto-end multi-face expression detection. Finally, we apply the model to smart classroom group emotion assessmentand provide design refe

Asperuloside Promotes Apoptosis of Cervical Cancer Cells through Endoplasmic Reticulum Stress-Mitochondrial Pathway

Chinese Journal of Integrative Medicine 2024年第1期30卷 34-41页

作者： QI Zhi-min WANG Xia LIU Xia zhao juan Medical Examination Center Hebei Province Hospital of Chinese MedicineShijiazhuang(050011)China Department of Gynaecology and Obstetrics Hebei Province Hospital of Chinese MedicineShijiazhuang(050011)China Experimental Center for Teaching Hebei Medical UniversityShijiazhuang(050017)China

Objective: To investigate the effects of asperuloside on cervical cancer based on endoplasmic reticulum(ER) stress and mitochondrial pathway. Methods: Different doses(12.5–800 μg/mL) of asperuloside were used to treat cervical cancer cell lines Hela and CaSki to calculate the half maximal inhibitory concentration(IC_(50)) of asperuloside. The cell proliferation was analyzed by clone formation assay. Cell apoptosis, intracellular reactive oxygen species(ROS) and mitochondrial membrane potential were determined by flow cytometry. The protein expressions of cleaved-caspase-3, Bcl-2, Bax, Cyt-c, cleaved-caspase-4 and glucose-regulated protein 78(GRP78) were analyzed by Western blot. And the inhibitor of ER stress, 4-phenyl butyric acid(4-PBA) was used to treat cervical cancer cells to further verify the role of ER stress in the apoptosis of cervical cancer cells induced by asperuloside. Results: Asperuloside of 325, 650, and 1300 μg/mL significantly inhibited the proliferation and promoted apoptosis of Hela and CaSki cells(P<0.01). All doses of asperuloside significantly increased intracellular ROS levels, reduced mitochondrial membrane potential, significantly reduced Bcl-2 protein expression level, and increased Bax, Cyt-c, GRP78 and cleaved-caspase-4 expressions(P<0.01). In addition, 10 mmol/L 4-PBA treatment significantly promoted cell proliferation and reduced apoptosis(P<0.05), and 650 μg/mL asperuloside could reverse 4-PBA-induced increased cell proliferation, decreased apoptosis and cleaved-caspase-3,-4 and GRP78 protein expressions(P<0.05). Conclusion: Our study revealed the role of asperuloside in cervical cancer, suggesting that asperuloside promotes apoptosis of cervical cancer cells through ER stress-mitochondrial pathway.

背景骨髓抑制是肺癌化疗常见的不良反应之一,针对化疗相关性骨髓抑制,现代医学多采用对症治疗,但存在一定局限性。目的探讨“子午流注”理论指导下择时揿针疗法预防肺癌化疗后骨髓抑制的效果。方法选择2020年7月—2022年6月在江苏省苏北人民医院呼吸科住院的142例首次行化疗的非小细胞肺癌(NSCLC)患者,按事先电脑生成的随机数字表和制订的分配方案,根据入院时间将研究对象随机分为对照组(47例)、揿针组(48例)及择时组(47例)。对照组给予肺癌化疗常规护理措施,揿针组在对照组措施基础上加用膈俞穴、脾俞穴、胃俞穴等穴位揿针疗法,择时组在对照组遵循子午流注纳子法于当日辰时(7:00—9:00)至巳时(9:00—11:00)实施择时揿针疗法。检测分析三组化疗前1 d及化疗第3、7、14、21天反映骨髓抑制情况的血常规指标及舒适度评分的变化情况。结果白细胞计数、中性粒细胞计数:揿针组和择时组化疗第7、14天均高于对照组(P<0.05),择时组均高于揿针组(P<0.05);血小板计数:化疗第7、14天揿针组和择时组均高于对照组(P<0.05)。舒适度评分:化疗第7、14天揿针组和择时组均高于对照组(P<0.05),化疗第14天择时组高于揿针组(P<0.05)。结论子午流注择时揿针疗法能有效预防NSCLC患者化疗后骨髓抑制,提高白细胞计数、中性粒细胞计数和血小板计数等部分血常规指标,提升患者的舒适度。
