    Subjects: Medicine, Pharmacy >> Preventive Medicine and Hygienics submitted time 2023-11-02 Cooperative journals: 《中国全科医学》

    Abstract: Background  In recent years,the prevalence of hypertension among the elderly in China has been consistently increasing. Current studies have found some association between hypertension and platelets,and platelet distribution width serves as the most sensitive measure of platelet activation,therefore,this study was conducted to explore the relationship between platelet distribution width and hypertension in elderly males and females. Objective  To investigate the correlation of platelet distribution width with various hypertension subtypes in the elderly males and females. Methods  A total of 600 elderly hypertensive and elderly non-hypertensive patients aged 65 years and above who were hospitalized in the Department of Cardiovascular Medicine,Hebei Provincial People's Hospital between 1 January 2020 and 24 April 2023 were consecutively enrolled and classified into 150 cases in the simple systolic hypertension(ISH) group,150 cases in the simple diastolic hypertension(IDH) group,150 cases in the systolic-diastolic hypertension(SDH)group,150 cases in the normotensive group based on hypertension measurements. Basic data of patients were collected,including age,gender,BMI,systolic blood pressure,diastolic blood pressure,creatinine,uric acid,total cholesterol,triacylglycerol,high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),fasting blood glucose,and platelet distribution width. Binary Logistic regression models were used to analyze the correlation between platelet distribution width and different hypertension subtypes. Results  Binary Logistic regression analysis showed that age,uric acid,and platelet distribution width were influencing factors in the occurrence of ISH in males(P<0.05);age,BMI,total cholesterol,triacylglycerol,HDL-C,LDL-C,and platelet distribution width were influencing factors in the occurrence of IDH in males(P<0.05).Moreover, BMI,uric acid,total cholesterol,triacylglycerol,HDL-C,LDL-C,platelet distribution width,and fasting blood glucose were identified as influencing factors in the occurrence of SDH in males(P<0.05). BMI,total cholesterol,triacylglycerol,and platelet distribution width were influencing factors in the occurrence of ISH females(P<0.05). BMI,triacylglycerol,HDL-C,and platelet distribution width were influencing factors in the occurrence of IDH in women(P<0.05). BMI,total cholesterol,triacylglycerol,HDL-C,LDL-C,and platelet distribution width were influencing factors for the occurrence of SDH in women (P<0.05). The sex-stratified analysis showed that,after adjusting for confounders such as age,BMI,creatinine,uric acid,total cholesterol,triacylglycerol,HDL-C,LDL-C,and fasting blood glucose,in males,the quartile 3 of platelet distribution width(12.1-<12.9 fL) was a risk factor for ISH(OR=8.893,95%CI=2.731-28.955),IDH(OR=5.265,95%CI=1.758-1.758),and SDH(OR=4.674,95%CI=1.549-14.102),while the quartile 4 of platelet distribution width(>12.9 fL) was a risk factor in the occurrence of SDH(OR=3.316,95%CI=1.177-9.345) compared to quartile 1 of platelet distribution width(≤10.7 fL); in females,compared to quartile 1 of platelet distribution width( ≤ 11.0 fL),the quartile 3 of platelet distribution width(12.4-<13.2 fL) was a risk factor for ISH(OR=3.494,95%CI=1.218-10.021) and SDH(OR=4.949,95%CI=1.283-19.089),quartile 4 of platelet distribution width(>13.2 fL) was a risk factor for ISH(OR=5.283,95%CI=1.786-15.633),IDH(OR=5.837,95%CI=1.544-22.068) and SDH(OR=4.966,95%CI=1.373-17.963). Conclusion  Among elderly males,platelet distribution width>12.1 fL is a risk factor for IDH and SDH. Among elderly women,platelet distribution width>12.4 fL is a risk factor for ISH and SDH,when platelet distribution width>13.2 fL,it is a risk factor for IDH.

  • Research on the Evaluation Framework of Open Source Intelligence from International Think Tanks

    Subjects: Library Science,Information Science >> Information Science submitted time 2023-04-01 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] The evaluation of the value of intelligence is the foundation of open source intelligence work. International think tanks have not received attention or been considered as an important source of open source intelligence, and theoretical research lags behind practical requirements. Research on evaluation of open source intelligence from think tanks aims to make relevant theoretical supplements to open source intelligence research of think tanks and provide references for open source intelligence practices in the field of think tanks. [Method/process] Focusing on the perspective of intelligence collection, this paper used deductive methods to demonstrate that open source is an important prerequisite for international think tanks as a source of open source intelligence. On this basis, combined with the characteristics of international think tanks, this paper also concluded that the open source intelligence of international think tanks has affordances of professionalism, policy-oriented, early warning, evidence-based and data value, which provides theoretical basis for open source intelligence evaluation. And under the guidance of the evaluation methods of Admiralty Code, the paper built an open source intelligence evaluation framework of international think tanks. [Result/conclusion] In the open source intelligence evaluation framework of international think tanks, intelligence personnel and professionals in the field need to establish cooperation and jointly act as evaluators. At the same time, evaluation objects conclude both the evaluation of intelligence sources and the evaluation of intelligence content. The evaluation of intelligence sources should focus on the professionalism, independence and credibility of think tanks; and the evaluation of intelligence content should consider 8 key elements including authenticity, integrity, timeliness, predictability, practicality, counterintelligence, understandability, and traceability.

    Abstract: [Purpose/Significance] This is the first systematic description and overall evaluation of the emergence, development and evolution of the Chinese librarians’ alliance in North America, which deeply reveals and accurately judges the identity and function of the alliance in the development of the global library and the construction of overseas Chinese society. [Method/Process] The formation process, structural evolution and strategic direction of the Chinese librarians’ alliance in North America were sorted out comprehensively. This paper focused on the background, process and impact of the formation of organizations such as the Council on East Asian Libraries, the Chinese American Librarians Association, and the Society for Chinese Studies Librarians, and analyzed the strategic significance of the cooperative alliance organizations of the China-US academic libraries alliance organizations in the era. [Result/Conclusion] The Chinese librarians’ alliance in North America has gone through the development stages of beginning, maturity, and deepening, moving from an early scattered group to a regional association, to a high-level qualitative change in the membership structure, to the creation of a deeply integrated professional model, and finally to a transnational alliance with the Chinese library community, building a strategic pattern of internal and external synergy and two-way win-win.

    Subjects: Other Disciplines >> Synthetic discipline submitted time 2023-03-28 Cooperative journals: 《中国科学院院刊》

    Abstract: Reducing CO2 emissions and increasing carbon sinks are basic approaches to achieve carbon neutralization in China. China is the largest mariculture country in the world. China’s mariculture industry is dominated by non-fed culture type and characterized by rich species, diverse nutrition levels, and advanced farming technology. Therefore, mariculture has huge potential for the development of ocean negative carbon emissions (ONCE). However, the ONCE process of bivalves and seaweed farming is complicated, and the scientific principles, process, mechanisms, monitoring and evaluating methods, and approaches of increasing carbon sink are gradually being recognized and yet to be resolved. This study discusses the research progress of fishery carbon sink, existing problems and possible impact of global climate change on ONCE of mariculture. It then proposes technological approachs and policy suggestions to implement ONCE , which include expanding mariculture space and increaseing unit yield, green development of mariculture based on carrying capacity regulatory regime, integrated multi-trophic aquaculture, blue carbon engineering of ocean ranching, and marine artificial upwelling.
