History, Narrative, and Faith: A Study of Du Guangting, the Tang Dynasty Imperial Censor in Nanzhao Yang Dongxia Journal of Dali University    2025, 10 (3): 1-.   DOI: 10. 3969 / j. issn. 2096-2266. 2025. 03. 001 Abstract （157）      PDF （1450KB）（16）    Knowledge map    Save An analysis of The historical narrative of "Du Guangting's Sojourn in Nanzhao" reveals that this narrative was formed through the renowned Tang Daoist figure Du Guangting by constructing, grafting, and appropriation. During the Nanzhao period, this narrative served as a discouerse text through which Nanzhao sought to construct an identity aligned with Tang Dynasty, while also functioning as a tool for internal ideological governance. Subsequently, this narrative underwent continuous "layered accumulation", eventually forming a localized discourse. The narrative gradually evolved into a form of Benzhu worship, which has been preserved and continues to exert influence to now. Du Guangting Benzhu worship represents a vibrant local historical narrative, embodying a historical microcosm of how local ruler and local people actively aligned themselves with central monarchy and central plains culture. It stands as a testament to forging of a strong sense of community for the Chinese nation. Reference | Related Articles | Metrics

Anti-Tumor Effect and Mechanism of CⅡ-3 Extractive from Periplaneta americana on S180 Sarcoma-Bearing Mice Lu Li, He Xu, Zhang Yanju, Peng Fang Journal of Dali University    2023, 8 (10): 1-8.   Abstract （154）      PDF （26926KB）（92）    Knowledge map    Save Objective：To investigate the anti-tumor effect and mechanism of CⅡ-3 extractive from Periplaneta americana on S180 sarcoma-bearing mice. Methods： S180 sarcoma-bearing mice were randomly divided into model group， positive control （CTX） group， high-dose， medium-dose and low-dose CⅡ-3 groups， and a normal control group， with 10 mice in each group. The pathological changes of tumor tissue in each group were observed after administration， and the tumor inhibition rate was calculated. ELISA kits were used to test the levels of vascular endothelial growth factor（VEGF） and telomerase（TE） in serum. The expression of p53， B-cell lymphoma 2（Bcl-2）， cysteinyl asparate specific protease-3（Caspase-3）， microvessel density （MVD） and cyclooxygenase-2（COX-2） protein in tumor tissue were detected by immunohistochemistry. Results： The tumor inhibition rates of CTX group， high-dose， medium-dose， and low-dose CⅡ-3 groups were 85.71%， 55.71%， 44.28%， 34.28%， respectively. The necrotic area of tumor tissue was obvious in high-dose and medium-dose CⅡ-3 groups. Compared with the model group， the TE activity was decreased in high-dose CⅡ-3 group（P<0.05）， and the expression of p53， Bcl-2， MVD and COX-2 in tumor tissues of high-dose and medium-dose CⅡ-3 groups were significantly decreased（P<0.01）， while the Caspase-3 expression was significantly increased（P<0.01）. Conclusion： CⅡ-3 can significantly inhibit the growth of S180 sarcoma， and its mechanism may be related to the reduction of TE activity， the decrease of p53， Bcl-2， MVD， COX-2 expression， and the increase of Caspase-3 expression in tumor tissue.

Masks-Wearing Face Recognition System Based on RetinaFace and FaceNet Algorithms Pei Yi, Liu Guangyu, Lei Yuanbin, Zhang Jilei, Chen Bobo, Zhao Hongyi, Zhao Enming Journal of Dali University    2024, 9 (12): 51-57.   Abstract （150）      PDF （2207KB）（8）    Knowledge map    Save During the epidemic outbreak, wearing masks has become an important public epidemic prevention measure. However, masks will lead to a reduction in recognition accuracy and a slowdown in detection speed of image-based face recognition systems. This study designs a masks-wearing face recognition system based on RetinaFace and FaceNet algorithms. First, the RetinaFace algorithm is used to train the RetinaFace model to realize the face key point positioning function. Secondly, the FaceNet algorithm is used to train the FaceNet model to extract the face feature vector and build a feature database. Finally, by comparing a Euclidean distance between the facial feature vector to be recognized and the vectors in the database, the recognition result is output. The experimental results show that the recognition speed of the system after RKNN model conversion exceeds 25 f/s. On the dataset Mask-LFW, when the Euclidean distance threshold between feature vectors is set to 1.01, the ACC is up to 93.78%, and the AUC is 91.03%. The system meets realtime requirements and has high detection accuracy, which can be used in laboratories, company offices, factories and some public places. Reference | Related Articles | Metrics
