Abstract： Background The occurrence and development of acute coronary syndrome（ACS）are closely associated with inflammatory responses，but the relationship between dietary inflammatory potential and severity of coronary artery disease of ACS patients is currently unknown. Objective To investigate the relationship between dietary inflammatory potential evaluated by Dietary Inflammation Index（DII）and severity of coronary artery disease in ACS patients. Methods Convenient sampling method was used to select 309 patients diagnosed as ACS for the first time by coronary arteriography in the Department of Cardiology，the Second Affiliated Hospital of Harbin Medical University from April 2022 to March 2023，and they were divided into DII-1 group（from -8.35 to -4.56），DII-2 group（from -4.55 to -0.77），DII-3 group（from -0.76 to 3.02）and DII-4 group（from 3.03 to 6.81）according to the quartile of DII，into Q1 group（4-32），Q2 group（34-52），Q3 group（54-84）and Q4 group（86-192）according to the quartile of Gensini score. Demographic and clinical features，overall DII，and DII of nutrient were compared in ACS patients with different severity of coronary artery stenosis，multiple Logistic regression analysis was used to analyze the relation of DII with the severity of coronary artery stenosis. Results There was significant difference in educational level，LDL-C，LP-a，overall DII，DII of total fat，saturated fatty acids，vitamin E，carotene in ACS patients with different severity of coronary artery stenosis，respectively（P ≤ 0.05）. After the correction of confounders of educational level，LDL-C and LP-a，the multiple Logistic regression analysis showed that，DII-4 group was the influencing factor of Q2 group［OR=15.389，95%CI（1.595，148.432）］，Q3 group［OR=15.102，95%CI（1.620，140.788）］ and Q4 group［OR=17.319，95%CI（1.901，157.807）］，respectively（P<0.05）；DII of total fat［OR=3.831，95%CI（1.195，9.094）］，saturated fatty acids［OR=8.562，95%CI（1.519，48.258）］ and vitamin E［OR=0.640，95%CI（0.460，0.890）］ was the influencing factor of Q4 group，respectively（P<0.05）. Conclusion Dietary inflammatory potential as well as inflammatory potential of nutrient total fat，saturated fatty acids and vitamin E are influencing factors of severity of coronary artery disease in ACS patients，thus clinicians should further strengthen the reasonable anti-inflammatory dietary guidance of ACS patients.

Abstract： [Purpose/significance] From the perspective of industry chain, this paper takes virtual reality technology as an example, constructs VR patent industry chain corpus, and explores the technical theme, research and development hotspot and future development trend of China VR patent. [Method/process] First of all, this paper used Python to crawl the patent text in VR field and got effective corpus through data cleaning. Secondly, combining IPC classification number and K-means clustering algorithm, this paper constructed and validates VR patent industry chain. In addition, based on TF-IDF algorithm and LDA theme model, we identified the core technology themes and their comprehensive strength, technology research and development hotspots and future trends of China VR patents from the perspective of production chain. [Result/ conclusion] At present, the proportion of patents in each link of China VR industry chain is unbalanced. The upstream link is the most popular, followed by the downstream link, and the weakest link is the midstream link. In terms of theme mining, the upstream hot spot is software development, the midstream hot spot is film and television production, and the downstream hot spot is medical, educational and entertainment applications. In terms of future trends, the upstream of the industrial chain will be dominated by technologies such as electronic digital data processing, optical components, image communication, etc., the midstream will be dominated by technologies such as vehicle components, power devices, damping devices, etc., and the downstream will be dominated by technologies such as indoor games, medical diagnosis, identification, etc.

Abstract： [Purpose/significance] The service level evaluation of domestic government open data can provide reference and basis for the objective evaluation and policy-making of government open data, thus improving the efficiency of domestic government open data.[Method/process] From the micro level of data and users perspectives, this paper established the evaluation framework of the service level of government open data. For example, "Cultural Leisure" thematic datasets on data open platform of Wuhan and other 8 platforms, using entropy method to calculate the comprehensive evaluation value of weight and government open data service level.[Result/conclusion] The service level of government open data is highly correlated with the availability of data, and it is hierarchical; the service level of government open data is inconsistent.
