The Security-Development Nexus: Connotations, Pathways, and Influencing Factors of China's Peripheral Diplomacy in the New Era Qi Weiqun , Xi Guigui Journal of Dali University    2025, 10 (9): 85-.   Abstract （28）      PDF （1494KB）（93）    Knowledge map    Save Since the 18th National Congress of the Communist Party of China, China has actively advanced its peripheral diplomacy by adhering to the principles of "treating neighbors with friendship and partnering with them", upholding "good-neighborliness, securing neighbors, and enriching neighbors", and highlighting the philosophy of "amity, sincerity, mutual benefit, and inclusiveness". In the new era, China′s proposal of the "Global Development Initiative （GDI）" and "Global Security Initiative （GSI）" has endowed China′s peripheral diplomacy with the critical connotation of balancing "security" and "development". This paper argues that the main pathways of China′s peripheral diplomacy include the expression of goodwill signals, institutional creation, and economic reciprocity. Meanwhile, the fundamental connotations consist of China′s own economic growth, its response to the challenges posed by the U. S. Indo-Pacific strategy, and its efforts to address the diverse security and development demands of Southeast Asian countries. Related Articles | Metrics

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.

The Development and Evolution of Traditional Rural Elite-Driven Governance, Its Experiences,#br# Wisdom and Practical Enlightenment#br# Zhang Sheng Journal of Dali University    2024, 9 (11): 121-128.   DOI: 10. 3969 / j. issn. 2096-2266. 2024. 11. 017 Abstract （88）      PDF （1409KB）（85）    Knowledge map    Save In traditional Chinese society, almost every village has nurtured virtuous people （elites） within its own local culture. They are similar to officials yet different; they are similar to the common people yet more powerful. The elites can convey public opinions through their own privileges, act as intermediaries between the government and the people, and directly participate and play a leading role in rural governance. Traditional rural elite-driven governance is the main mode of traditional rural social governance. Looking at its development, its content has gradually evolved from being solely responsible for moral education to directly participating in specific rural affairs. Traditional rural elite-driven governance has promoted rural autonomy, developed public welfare undertakings, flourished rural culture, and consolidated rural strength. It fully reflects the sage-like color of traditional Chinese politics and prominently showcases the experience and wisdom of grassroots governance in China. Summarizing its experience can bring some practical inspirations for new elites to participate in rural governance in the context of the new era, and it is worthy of exploration and research.

Cultural Strategy, Narrative Translation and Order Shaping: A Study on the Mechanism of Yunnan#br# Myths Consolidating the Sense of Community for the Chinese Nation#br# Sun Haoran, Cheng Bo Journal of Dali University    2024, 9 (7): 1-9.   DOI: 10. 3969 / j. issn. 2096-2266. 2024. 07. 001 Abstract （101）      PDF （1608KB）（81）    Knowledge map    Save Historically, various ethnic groups in Yunnan have consciously and continuously intervened in the "original narrative" to achieve the reconstruction of "secondary narrative" in the long-term process of interaction, communication and integration. Through the translation process of decoding and coding, they have transformed the secular into the sacred, the conflict into harmony, and the non-community into the community, and finally constructed a set of sacred narrative system. Yunnan myth, as a reflection of historical reality, cultural reality and social fact, is a cultural strategy with emotion, metaphor, folk and enlightenment in daily life. This cultural strategy can influence the goal setting and action choice of regional ethnic groups, and promote the conscious formation of regional ethnic community and even Chinese national community. Yunnan mythology, specially the "myth of the Chinese nation community", contains rich consciousness of the Chinese national community and is the "knowledge inventory" to cast the sense of community for the Chinese nation.

Investigation on the Carrier Rate and Antifungal Susceptibility of Yeast Species Isolated from External Urethral Meatus of Healthy College Students Bai Zongkai, Lü Neng, Liu Runhua, Luo Yuanxi, Wu Qiuyue, Xu Jing, Wu Youcong Journal of Dali University    2023, 8 (4): 34-38.   Abstract （148）      PDF （4609KB）（76）    Knowledge map    Save Objective： To investigate the yeast carrier rate， species distribution and susceptibility to common antifungal drugs in external urethral meatus of healthy college students. Methods： A total of 261 healthy university students were randomly recruited from a university in Yunnan Province， and the swabs from urinary meatus were collected for isolation， identification， drug sensitivity testing， and statistical analysis. Results： 39 yeast species were isolated，with a carrier rate of 14.9%；  among them， 6 strains were isolated from 130 male samples， with a carrier rate of 4.6%， while 33 strains were isolated from 131 female samples， with a carrier rate of 25.2%. The difference of carrier rate between different gender groups was statiscally significant（χ2=21.73，P=0.005）. Among 39 yeast species， there were 11 strains of Candida albicans（28.2%）， 24 strains of Candida glabrata（61.5%）， 4 strains of other Candida species（10.3%）. The result showed that the geometric means of the yeast to fluconazole， flurocytosine and amphotericin B were 22.03， 0.16 and 4.37 μg/mL， respectively， and the drug resistance rates of isolates were 15.4%， 0.0% and 100.0%， respectively. Conclusion： The prevalence of Candida colonization among healthy college students at urinary meatus is relatively low， with smooth colony Candida glabrata being the predominant species.The colonization rate of Candida among female students is significantly higher than that among male students. Some Candida strains exhibit intrinsic resistance to commonly used antifungal drugs. Reference | Related Articles | Metrics

Expression of SOX9 in the Directed Differentiation of Mouse Hepatic Oval Cell into Biliary Epithelial Cells Huang Shan, Jin Liquan, Yu Yu, Huang Ji, Zhang Junhua, Chen Yiming Journal of Dali University    2023, 8 (4): 22-27.   Abstract （91）      PDF （7480KB）（72）    Knowledge map    Save Objective： To investigate the expression changes of SOX9 during the directed differentiation of mouse hepatic oval cell （HOC） into biliary epithelial cell（BEC）. Methods：A mouse HOC activation model was established by 2-acetylaminofluorene gavage and 2/3 partial hepatectomy. HOC were extracted by two-step enzyme digestion and Percoll density gradient centrifugation， and then induced to differentiate into BEC by using epidermal growth factor（EGF）， stem cell growth factor（SCF） and leukemia inhibitory factor（LIF） in vitro. Cell morphological changes before and after differentiation were observed under inverted microscope， BEC were identified by flow cytometry， and the expression of SOX9 before and after differentiation was detected by immunofluorescence.Results： HOC were differentiated into purer BEC up to the 8th generation under the joint action of EGF， SCF and LIF. SOX9 was mainly expressed in the cytoplasm of primary mouse HOC， and gradually entered the nucleus during differentiation， with a significant increase in average light density value. Conclusion： SOX9 enters the nucleus and its expression remarkably increases during differentiation of mouse HOCs into BECs， indicating its possible involvement in the regulation of this differentiation process.
