Effect of combining valsartan and amlodipine in the treatment of type 2 diabetes mellitus complicated by hypertension

Purpose: To investigate the efficacy of combining valsartan and amlodipine on patients who were co-morbid with type 2 diabetes mellitus (T2DM) and hypertension.
 Methods: The medical records of 110 patients treated in North China Electric Power University Hospital, Beijing, China from July 2018 to October 2022 were retrospectively analyzed. Control group (CG; n = 50) was administered oral amlodipine (5 mg daily for 6 months), while the study group (SG; n = 60) received one tablet of co-formulated valsartan (80 mg)) and amlodipine (5 mg) daily for 6 months. All the patients, in addition to the above drugs, were also placed on insulin and atorvastatin calcium. After a 6-month treatment period, the therapeutic effect and incidence of adverse effects were compared between CG and SG. Blood glucose-related indices (glycosylated hemoglobin (HbA1c), 2 h postprandial blood glucose (2 h PG), and fasting blood glucose (FBG)) and blood pressure indices, viz, (diastolic blood pressure (DBP), systolic blood pressure (SBP)) were compared.
 Results: Compared to the pre-treatment values, both groups showed significant decrease in 2 h PG, FBG, HbA1c, SBP and DBP after treatment (p < 0.05), but the 2 h PG, FBG, HbA1c, SBP and DBP in SG were significantly lower in comparison to CG (p < 0.05). The overall response rate (ORR) of CG was significantly lower in comparison to SG (p < 0.05). In SG, there was significant reduction in the incidence of adverse effects compared to CG (p < 0.05).
 Conclusion: The combination of valsartan and amlodipine is effective in treating T2DM co-morbid with hypertension, and satisfactorily controls blood glucose level and blood pressure with a relatively high level of safety. Further experiments would be required to ascertain the reliability of these findings.

Sensitivity analysis in multi-criteria decision making: A state-of-the-art research perspective using bibliometric analysis

In the present era, the implementation of scientifically grounded Multi-Criteria Decision Making (MCDM) has emerged as a pivotal solution to diverse decision-making challenges across various domains. Although a substantial body of exploratory, conceptual, and experimental studies exists, only 9.457% studies have incorporated sensitivity analyses to assess the robustness of MCDM methods. An exhaustive scientific exploration of sensitivity analysis within the scope of MCDM is thus lacking. This research aims to address this gap through Bibliometric Analysis while examining 1374 articles published between January 2000 and March 2023 from the Scopus database. Using RStudio (Biblioshiny), CiteSpace, and VOSviewer software, the study constructs a visual representation of the most prolific countries, institutions, and authors. Impressively, China takes the lead in article publications, while India excels in international collaboration. “An extended TODIM multi-criteria group decision-making method for green supplier selection in an interval type-2 fuzzy environment,” featured in the Journal of Environmental Management, emerges as the most cited paper with a total citation of 455. The study also identifies the top three most cited journals, namely “Journal of Cleaner Production,” “Expert Systems With Applications,” and “Computers and Industrial Engineering.” “North China Electric Power University” is the leading institute with the highest research outputs. “Pamučar D” is the most cited author, with 2594 citations and 39 articles, followed by “Kahraman C” and “Zavadskas EK. This study sheds light on trends in scientific developments and collaborations, providing a model for the application of sensitivity analysis in MCDM research and highlighting global trends. An understanding of the current state of sensitivity analysis research can assist researchers working in the entire domain of MCDM. Additionally, the visualization provides prescriptive data for future work and applications related to sensitivity analysis.

Bibliometric Analysis of Game Theory on Energy and Natural Resource

This paper uses CiteSpace software to conduct a bibliometric analysis of research literature under the topic of game theory which specifically focuses on energy and natural resources in the Web of Science Core Collection. The results show that: since 1990, the number of documents covering the topics of “energy” and “game theory”, and “natural resources” and “game theory” has continued to grow steadily, and entered an explosive growth stage after 2017. In terms of disciplinary classification of published papers, Energy & Fuels has the highest frequency, 311 with a significant centrality, 0.22. In terms of journal publications, Applied Energy is the most cited journal whose frequency is 311 and centrality is 0.01. In terms of country, China has the highest number of published papers, and the United States with the highest overall centrality of papers. North China Electric Power University published 31 papers, the largest number of documents from one institution. In terms of author productivity, Puyan Nie has been the most productive author since 2016. The co-citation cluster analysis on the literature topics shows that the game theory of energy and natural resources have roughly gone through four stages: (1) From 1990 to 2009, this is the embryonic stage with no more than 15 new papers per year; (2) From 2010 to 2014, this stage had microgrid as its mainstream research topic, and other topic clusters officially emerged; (3) From 2015 to 2017, the main research topics became the integrated energy system, subsidy mechanism and household energy management, with a hot topic on the evolutionary game process between government and enterprises; (4) From 2018 to 2021, this stage continued to focus on the previous topics, and the research goes much deeper, resulting in more models and new green technologies. Finally, the keyword analysis concludes with nine themes of concern in this research field, and has come to a comprehensive summary of the mainstream research methods in the field of game theory of energy and natural resources.

Dependence of dynamic resistances in high-temperature semiconducting quasi-isotropic strands on magnitude and orientation of AC magnetic field

The dynamic resistance of a superconductor appears if it carries a direct current (DC) current and is simultaneously exposed to alternative current (AC) magnetic fields if its amplitude is higher than its full penetrated field. Due to its strong anisotropy, the dynamic resistance of high-temperature superconducting (HTS) tape is not only affected by the magnitude of AC magnetic fields but also their orientations. In particular, the dynamic resistance has considerable effect on the current distribution in HTS cables (except for Roebel cables) and even cable-in-conduit conductors made from those HTS cables, except for dissipative loss. This paper presents the behavior of dynamic resistance in an HTS quasi-isotropic strand (Q-IS), which consists of four sub-stacked 2G HTS tapes proposed by our group at North China Electric Power University, while it carries a DC current and simultaneously experiences an AC magnetic field with different magnitudes and orientations. An angular dependence of dynamic resistance in a single 2G HTS tape in an AC magnetic field with various orientations is first performed in simulations and experiments, respectively. The experimental results are in good agreement with the simulated ones, which shows that the dynamic resistance of a Q-IS also exhibits quasi-isotropic characteristics and has an important effect on the distribution of DC transport current. The related results are promising for the design and application of other DC HTS cables, feeders and magnets.
