Authors: Tanaka Tatsuya , Goto Hirofumi , Momozaki Nobuaki , Honda Eiichiro , Suehiro Eiichi , Matsuno Akira
Published: September 2024

Background:

Even mild head trauma can cause severe intracranial hemorrhage in patients with cerebrospinal fluid (CSF) shunts for hydrocephalus. CSF shunts are considered a risk factor for subdural hematoma (SDH). The management of acute SDH (ASDH) in shunted patients with normal pressure hydrocephalus can be challenging. Addressing the hematoma and the draining function of the shunt is important. To preserve the shunt, we set the shunt valve pressure to the highest and perform hematoma evacuation for ASDH. In this study, we report the surgical cases of ASDH in patients with shunts.

Methods:

Between 2013 and 2019, five patients with ASDH and CSF shunts underwent hematoma evacuation at our hospital. We retrospectively analyzed data regarding their clinical and radiological presentation, hospitalization course, the use of antithrombotic medications, and response to different treatment regimens.

Results:

The patients presented with scores of 5–14 in the Glasgow coma scale and severe neurological signs, consciousness disturbance, and hemiparesis. Most patients were elderly, taking antithrombotic medications (four of five cases), and had experienced falls (4 of 5 cases). All patients underwent hematoma evacuation following resetting their programmable shunt valves to their maximal pressure setting and shunt preservation. ASDH enlargement was observed in only one patient who underwent burr-hole drainage. Glasgow outcome scale scores at discharge were 1 and 3, respectively.

Conclusion:

In hematoma evacuation, increasing the valve pressure may reduce the bleeding recurrence. To preserve the shunt, setting the shunt valve pressure to the highest level and performing endoscopic hematoma evacuation with a small craniotomy could be useful.
Occurrence of malignant cerebral infarction following intracranial hematoma evacuation in traumatic brain injury: A case report
Authors: Pangaribuan Vega , Apriawan Tedy , Turchan Agus
Published: September 2024

Background:

Traumatic brain injury-related cerebral infarctions are well-documented in the literature. We want to report a case of malignant cerebral infarction that occurred at the contralateral location of evacuated epidural hematoma 3 days after surgery. The early-onset cerebral infarction’s clinical presentation was already evident during the initial clinical examination, and it resembled “Kernohan’s Notch Syndrome.”

Case Description:

A 57-year-old male Indonesian was taken to our Academic General Hospital’s emergency room following a motorcycle accident. His primary complaints were reduced consciousness and left-sided hemiparesis. A head computed tomography (CT) scan revealed an intracerebral hematoma beneath an epidural hematoma (EDH) at the left temporal area. The EDH was surgically removed promptly. The patient’s Glasgow coma scale improved, and they were able to follow commands afterwards. The patient had a decreased consciousness 3 days after the surgery. A malignant infarction of the right middle cerebral artery region was identified from the head CT scan evaluation. He immediately had an emergency decompressive craniectomy and had an improvement of consciousness following the surgery.

Conclusion:

It is imperative to reassess the initial clinical signs of Kernohan’s notch phenomenon to determine whether the offending mass was able to generate this clinical phenomenon. Initial cerebral infarction, which occurs concomitantly with traumatic intracranial hematoma, is a possible cause of clinical deterioration following the surgery.

Tüketiciler satın alma kararları verirken kişilik yapıları, finansal durumları ve diğer birçok faktörden etkilenmektedir. Satın alma kararları rasyonel olabileceği gibi aynı zamanda rasyonel olmayan çok fazla durumu da bünyesinde bulundurmaktadır. Kişilerin finansal iyi oluş düzeyleri de kişilik yapılarından, verdikleri finansal kararların sonucunda elde ettikleri maddi kazançlardan ve finansal davranış boyutları gibi birçok durumdan dolaylı ve doğrudan etkilenmektedir. Bu çalışmanın amacı, tüketicilerin D tipi kişilik özelliklerinin kendilerinin finansal iyi oluş ve kompulsif satın alma davranışı üzerindeki etkisi aynı zamanda finansal iyi oluş düzeylerinin de kompulsif satın alma davranışı üzerine etkisini ortaya koymaktır. Çalışmada, Denizli ilinde ikamet eden 18 yaş üzeri ve çalışır durumda olan 658 katılımcıya anket uygulanmıştır. Araştırma sonucunda; D tipi pozitif kişilik boyutunun finansal iyi olma haline etkisinin düşük, kompulsif satın almaya ise çok düşük etkisinin olduğu sonucuna varılmıştır. D tipi negatif kişilik durumunun ise finansal iyi olma haline küçük bir etkisi varken kompulsif satın alma davranışına ise çok küçük bir etkisinin olduğu bulunmuştur. Ayrıca çalışma sonucunda finansal iyi olma halinin ise yine kompulsif satın alma davranışına küçük bir etkisinin olduğu tespit edilmiştir.

Kimlik siyasetinin 1960’lar ile politik alanın en önemli tartışma nesnelerinden biri olması ve bu tartışmaların muhalif habitusu ikiye bölmesi gözlemlenebilir bir olgudur. Bununla birlikte özellikle 2010’larla başlayan, sosyal medyanın aracılığıyla hızlanan ve yaygınlaşan başka bir tür muhalefet biçiminin yeni kamusal alanlarda kendini gösterdiğini gözlemliyoruz. Woke (Uyanış) aktivizmi olarak adlandırılan bu hareket bir tür hiper-kimlik siyaseti ile ciddi destekçiler bulurken öte taraftan özellikle kullandıkları yöntemlerle ilgili olarak sert bir biçimde eleştiriliyorlar. Woke taraftarları, toplumsal cinsiyet normları, etnik aidiyet, göç ve çevre gibi sorunlar hakkında son derece duyarlıyken bu duyarlılığın dile getiriliş pratikleri öteki politik gruplar tarafından sorunsallaştırılmaktadır. Bu hiper-kimlik hareketinin üyeleri, özellikle sosyal medya kullanıcılarının kamuya açık olarak ifade ettikleri görüşleri hem içerik hem de seçilen sözcükler bağlamında sürekli eleştirmekte ve Woke filtresine takılanlar için yine sosyal medyada yoğun bir eleştiri fırtınası başlatmaktadırlar. Son kertede literatüre “iptal etmek” olarak geçen bu süreç, fail için geri dönülmez bir aşamaya geçebilmekte ve tüm yaşamını etkileyebilmektedir. Bu bağlamda biz çalışmamızda Woke aktivizminin belirli bir çerçevesini oluşturmaya çalışacağız. Bu çerçeve, Woke’un kavramsal olarak konumlandığı yerin tarihsel dinamikleri ve özellikle kavrama yönelik eleştirilerle oluşturulacaktır.

Published: September 2024

This study aims to determine the impact of creative self-efficacy and green shared vision on the inclination of employees in the logistics sector to engage in green innovative behaviour. The study's population comprises 564,323 individuals employed in the logistics sector in Turkey. Information was acquired via an internet-based questionnaire. Hence, the study's sample comprises 421 individuals who were chosen from the pool of employees. The analysed data was subjected to frequency analysis, exploratory factor analysis, reliability analysis, normality analysis, correlation analysis, and regression analysis. The correlation study revealed a substantial association between creative self-efficacy and green shared vision, creative self-efficacy and green innovative conduct, and green shared vision and green innovative behaviour. According to the results of the regression analysis, it was determined that creative self-efficacy and green shared vision had significant effects on green innovative behavior tendencies. According to regression analysis, creative self-efficacy was found to affect green innovative behavior tendencies more than green shared vision. Consequently, suggestions were put forward to highlight the significance of a collective environmentally friendly vision to all staff members in this particular group. This study is considered novel because there is no existing research example in the literature that evaluates the impact of creative self-efficacy and green shared vision on green innovative behaviour tendencies.

The Impact of Financial Development, Foreign Direct Investment and Geopolitical Risk on CO2 Emissions: Evidence from Turkey
Authors: Aydın Şehmus , Öztutuş Ferhat , Polat İbrahim Halil
Published: September 2024

The rise in greenhouse gas emissions, particularly carbon dioxide (CO₂), represents one of the most significant challenges facing humanity's existence in the 21st century. It is crucial to implement the measures to reduce these emissions to achieve environmental sustainability. Turkey, along with many nations, is striving to reduce its CO₂ emissions in accordance with the United Nations' 2030 Sustainable Development Goals. This study explores the effects of financial development (FIN), foreign direct investment (FDI), and geopolitical risk (GPR) on Turkey's CO₂ emissions, using annual data from 1985 to 2022. To investigate long-term relationships among these variables, we apply the RALS-Fourier ADF (RALS-FADF) unit root test, the Fractional Fourier ADL (FFADL) cointegration test, and the Fully Modified Ordinary Least Squares (FMOLS) method. The evidence from the FMOLS show that FIN, FDI, and GPR lead to higher CO2 emissions in Turkey over time. It is concluded that any policies designed to achieve a sustainable environmental quality in Turkey must consider mitigating the negative effects of the financial development, foreign direct investment and geopolitical risks on the environment.
Participation of N. A. Berdyaev in the activities of the Russian Student Christian Movement (RSCM) in 1923–1935
Authors: Гутнер У.А.
Published: September 2024

В статье рассматривается история участия Н. А. Бердяева в Русском студенческом христианском движении (РСХД). На основе анализа архивных данных, публикаций в «Вестнике РСХД» и мемуарной литературы изучается деятельность Бердяева в РСХД в период с 1923 по 1930-е гг. Деятельность развивалась в нескольких направлениях: руководство молодежными кружками в Берлине (1922–1925) и Париже (1925–1932), лекционные поездки по странам Европы и Прибалтики с целью организации кружков РСХД, участие в местных и общих съездах, начиная с первого Пшеровского съезда. Показана связь публикаций Бердяева в «Вестнике РСХД» и других журналах с его деятельностью в РСХД и размышлениями о путях развития Движения. В начале существования РСХД в 1923–1928 гг. Бердяев ценил его как новую, творческую форму жизни церкви, но в то же время подвергал критике в разные периоды его деятельности. В приложении к статье опубликован «Меморандум», написанный Бердяевым в декабре 1926 г. В этом документе, который впервые вводится в научный оборот, отражены взгляды Бердяева на церковный раскол 1926 г. (обличение Карловацкого синода в излишнем консерватизме и политизации церкви) и тезисно сформулированы принципы, на которых, с точки зрения Бердяева, основано Движение: взаимосвязь свободы и соборности, ответственность мирян за жизнь церкви, церковность и творческое христианское отношение к решению социальных проблем общества, апологетика христианства в современном мире и сотрудничество с западными христианскими вероисповеданиями.

The article examines the history of N. A. Berdyaev’s participation in the activities of the Russian Student Christian Movement (RSCM). Based on the analysis of archival data, publications in the “Bulletin of the RSHD” and memoirs, the activity of Berdyaev in the RSHD is studied in the period 1923–1930s, which developed in several directions: leadership of youth circles in Berlin (1922–1925) and Paris (1925–1932), lecture trips across Europe and the Baltic countries with the aim of organizing RSHD circles, participation in local and general congresses, starting with the first Psherovsky congress. The connection between Berdyaev’s publications in the “Vestnik RSHD” and other journals with his activities in the RSHD and his thoughts about the ways of its development is shown. In the appendix to the article, a “Memorandum” written by Berdyaev in December 1926 is published. This document reflects Berdyaev’s views on the church schism of 1926 (exposing the Karlovac Synod of excessive conservatism and politicization of the church) and the principles on which, from Berdyaev’s point of view, the Movement was founded: the relationship between freedom and conciliarity, the responsibility of the laity for the life of the church, churchliness and a creative Christian attitude to solving social problems of society, apologetics of Christianity in the modern world and cooperation with Western Christian denominations.
Composition Variation Reveals the Non-Ideal Mixing of Components in (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O and the Benefits of this Variation in Sodium Ion-Battery
Authors: Tegomoh Modeste , Lee Kug-Seung , Co Anne
Published: September 2024

The reversible transformation between a multiphase and single-phase state has been used as a hallmark for entropy stabilization in the system (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O. it was shown that cations are fully random and homogeneous in this single-phase material, providing a way to estimate its configurational entropy. The deliberate variation of this entropy led to the conclusion that (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O is primarily stabilized by this configurational entropy. Here, we show that this phase transformation observed in (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O could originate from a Jahn-Teller distortion rather than entropy stabilization. We further demonstrate through composition variation that the consolute temperature depends on the nature of the components rather than the number of components. In addition, we show that there is significant cation ordering in these systems, further casting doubts on the role of configurational entropy as the main stabilizing term. Finally, we demonstrate that this compositional variation can be used to tune the voltage of these complex metal oxides to improve their reactivity in a sodium-ion cell.

Published: September 2024

The escalating demands of industrialization and development underscore the necessity for an efficient and scalable Carbon Capture and Storage (CCS) methodology. Mineral carbonation of MgO presents itself as a promising solution due to its considerable theoretical capacity for CO2 adsorption. However, the sluggish kinetics of the carbonation process pose a significant challenge. Consequently, a comprehensive understanding of the structural and chemical alterations occurring during carbonation is imperative for material design. In this study, we conduct a thorough structural and chemical investigation of the MgO (sourced from different mine tailings) carbonation process using electron microscopic techniques. Our findings demonstrate that treating MgO with polar solvents enhances its degree of carbonation significantly, offering a promising avenue for improvement. Moreover, we observe a particle size dependency in MgO carbonation and note that the inclusion of additional materials, such as Si-based compounds, further accelerates the carbonation. Density functional theory (DFT) calculations provide insight into surface functionalization as a result of solvent treatment and its mechanistic effect on the origin of the enhanced carbonation of polar solvent-treated MgO, revealing a stronger interaction between CO2 and the treated MgO (100) surface as compared to the non-polar solvent treated surfaces. These discoveries showcase an alternative approach for enhancing MgO carbonation, thereby offering a potential method for sequestering atmospheric CO2 more effectively using mine waste rich in MgO.

Published: September 2024

Ensemble-average sampling of structures sampled from ab initio molecular dynamics (AIMD) simulations can be used to predict theoretical extended X-ray absorption fine structure (EXAFS) signals that closely match experimental spectra. However, AIMD simulations are time-consuming and resource-intensive, particularly for solvated lanthanide ions, which often form multiple non-rigid geometries with high coordination numbers. To accelerate the characterization of lanthanide structures in solution, we employed the Northwest Potential Energy Surface Search Engine (NWPEsSe), an adaptive-learning global optimization algorithm, to efficiently screen first-shell structures. As case studies, we examine two systems: Eu(NO3)3 dissolved in acetonitrile with a terpyridine ligand (terpyNO2), and Nd(NO3)3 dissolved in acetonitrile. The theoretical spectra for structures identified by NWPEsSe were compared to both experimental and AIMD-derived EXAFS spectra. The NWPEsSe algorithm successfully identified the proper solvation structure for both Eu(NO3)3(terpyNO2) and Nd(NO3)(acetonitrile)3, with the calculated EXAFS signals closely matching the experimental spectra for the Eu-ligand complex and showing good similarity for the Nd salt; the better agreement with the ligand-containing structure is attributed to a less dynamic coordination environment due to the rigid ligand. The key advantage of the global optimization algorithm lies in its ability to sample the coordination environment across the potential energy surface. The structure identification process can be done with a variety of methods and generally has reduced the time required from a month to within a week.
Metal-Organic Frameworks for the Trace Multiplexed Adsorption and Quantitation of 50 Per- and Polyfluoroalkyl Substances
Authors: Hua Lisa , Solomon Marcello , D'Alessandro Deanna , Donald William
Published: September 2024

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants that pose significant health risks. With recent regulatory guidelines lowering safe drinking water advisory limits to parts-per-quadrillion (ppq) levels, the need for methods capable of detecting and quantifying many PFAS simultaneously in trace amounts has become increasingly critical. In this study, six metal-organic frameworks were evaluated as solid-phase extraction sorbents for multiplexed adsorption of PFAS, followed by quantitative liquid chromatography-tandem mass spectrometry. UiO-66 demonstrated the highest performance with 87% adsorption efficiency and 85% recovery for 33 PFAS spiked at 2 parts per billion. In multiplexed adsorption for 50 PFAS at concentrations of 200 ppq, UiO-66 achieved an average recovery of 75%, with detection limits as low as 4 ppq and an average detection limit of 108 ppq. Validation using six environmental water samples revealed quantifiable PFAS in all samples with 25 PFAS detected. Compared to polymeric resins, which typically detect PFAS in the 1–80 parts per trillion range, UiO-66 demonstrated enhanced sensitivity for multiplexed adsorption, capable of detecting concentrations in the low ppq range. These findings highlight the potential of UiO-66 for large-scale PFAS monitoring under increasingly stringent environmental regulations.
Coupled Cation-Electron Transfer at Pt(111)/Perfluoro-Sulfonic Acid Ionomer Interface and Kinetic impact on the Oxygen Reduction Reaction

Published: September 2024

Electrochemical interfaces between polymer electrolytes and metal electrodes are central to many key electrochemical devices in the global sustainable energy transition, however, much of the electrochemical insights were gained at the liquid/solid electrochemical interfaces. In this work, we analyze the adsorption and desorption processes of sulfonate groups in Nafion, the most widely used polymer electrolyte and binder, on Pt(111), and demonstrate that they are distinct from specific adsorption of common anions in the following aspects: 1) The main thermodynamic driving force for the specific adsorption of sulfonate groups is not the chemical bonds formed between the anion and the surface. 2) The adsorption and desorption of sulfonate in Nafion on Pt(111) involve distinct elementary steps, with the latter proceeding through a coupled cation-electron transfer. 3) Adsorbed sulfonate groups in Nafion not only block a fraction of surface Pt sites, but more importantly, generate two new types of surface adsorbates, i.e., OHNafion and ONafion, which exhibit distinct kinetic properties from adsorbed OH and O on bare Pt(111), respectively. The impact of adsorbed Nafion on the activity of the oxygen reduction reaction (ORR) cannot be rationalized by existing thermodynamic descriptors, e.g., OH binding energy. The reduced ORR activity on Nafion-covered Pt(111) is caused by the kinetically slower *O → *OH conversion and *OH reduction on the Pt sites in the vicinity of adsorbed sulfonate groups. Our findings highlight that the kinetic properties of key surface intermediates must be taken into account in the design of ORR catalysts.

Harnessing biological systems for the hydrogen economy requires a thorough understanding of the responsible iron-sulfur (FeS) cluster-containing proteins. This study focuses on the HydA1 hydrogenase of Chlamydomonas reinhardtii (CrHydA1), a simplistic and well-characterized [FeFe]-hydrogenase and employs electron paramagnetic resonance (EPR) spectroscopy for studying the complex paramagnetic states of its FeS cluster. We report the existence of two distinct cluster species arising from a single [4Fe4S]-cluster within the apo-form of the enzyme. Multi-frequency and variable-temperature pulsed EPR experiments revealed the interconversion of the two dominating species, characterized by their axial and rhombic EPR responses. The species interconvert depending on redox potentials and pH levels. Molecular dynamics simulations and quantum mechanical calculations identified two secondary-sphere residues, Arg227 and Lys228, as potential causes of the binary response of the [4Fe4S] cluster. These amino acids can adopt inner and outer conformations relative to the [4Fe4S] cluster, causing valence rearrangement and thus providing a plausible explanation for the observed spectroscopic differences. The dynamic behavior of these cluster species not only suggests a central role in the catalytic mechanisms of hydrogenases but also offers valuable insights for the analysis of other FeS-containing metalloproteins with comparable characteristics.

This article focuses on the relationship between coursework and field experience, theory and practice. Guided by Korthagen et al.’s (2006) fundamental principles for teacher education, an alternative student teaching structure was tested at the Université du Québec en Outaouais (Canada) in the Fall 2016 term. An online survey was conducted to elicit feedback on how this structure helped enhance the link between theory and practice, according to student teachers, mentor teachers, and teacher educators. Results show the structure offered student teachers the opportunity to reinvest learning in both theory and practice and to discuss the tensions between the two, which represented a significant moment in the program’s development.
Does Digitalization Increase Economic Growth? Evidence from SADC Countries
Authors: Mhaka Simbarashe , Taonezvi Lovemore
Published: September 2024

The fourth industrial revolution has contributed significantly towards the growing global technological transfers that enhance productivity, employment and standard of living. The outbreak of the COVID-19 pandemic has undeniably disrupted lives globally; however, it enhanced technological transformation by causing an abrupt shift towards digital technology usage. The development and diffusion of digitalisation is expected to drive economic growth as we move towards the 2030 Sustainable Development Agenda. This study examines the impact of digitalisation on economic growth for 14 Southern African Development Community (SADC) countries from 2000 to 2020 employing the Fixed Effects model. Results reveal that all digitalisation indicators employed tend to have a positive impact on economic growth. A percentage change in individual usage of information communication technologies (ICTs), fixed broadband subscriptions, and mobile cellular subscriptions leads to a 0.17%, 0.11% and 0.12% increase in GDP per capita, respectively. Therefore, usage of and access to digital technologies stimulate economic growth in the SADC region. Public policies should seek to  stimulate private sector investments in technological infrastructure and liberalise the telecommunications and innovation market. This accelerates digitalisation and consequently leads to higher economic growth and development in the SADC region.
An updated checklist of spiders (Arachnida, Araneae) of the protected areas of the Kherson region (Ukraine)
Authors: Iosypchuk A.M.
Published: September 2024

The protected areas of Kherson region include 84 sites of different categories, of which only one-tenth been studied in terms of spider diversity. It is advisable to use the results of long-term monitoring of flora and fauna to assess the level of conservation of protected areas, including species composition, abundance, and character of spider communities, Accordinly, a list of spider species of nine objects of the Nature Reserve Fund of Ukraine has beed compiled It includes two bdiosphere reserves, five national nature parks, and two preserves. The literature data were supplemented with the results of my research in 2021 on the territories of the Dzharylhatskyi and Oleshkivski Pisky Nature Parks. The spider fauna of the protected areas of the Kherson region includes 363 species of 30 families. Ten species Cyclosa sierrae Simon, 1870, Eresus moravicus Řezáč, 2008, Nomisia exornata (C.L. Koch, 1839), Oxyopes globifer Simon, 1876, Pirata piscatorius (Clerck, 1757), Singa semiatra L. Koch, 1867, Trochosa hispanica Simon, 1870, Zelotes tenuis (L. Koch, 1866), Erigonoplus jarmilae (Miller, 1943), Titanoeca spominima (Taczanowski, 1866) were recorded for the first time from the Kherson region. The latter two were added to the list after reviewing the collection of spiders from the Chornomorskiy Biosphere Reserve. For the first time in Ukraine, Neaetha absheronica Logunov & Guseinov, 2002 (1 male; June ‒ July 2021; 46.025905N, 32.934212E) was found in a psammophytic steppe of a wide part of the Dzharylgach Spit ('Dzharylhatskyi' NNP), which extends the northern border of the species' range. The genus Neaetha (Salticidae) is also new to Ukraine. The records of Eresus kollari Rossi, 1846, Civizelotes pygmaeus (Miller, 1943) and Minicia marginella (Wider, 1834) need to be confirmed. According to the author's estimates, the spider fauna of the Kherson region includes approximately 400 species. Among the upcoming research, it is planned to make an inventory of the spider fauna and analyze their communities to assess the impact of hostilities, as well as to update the information on the spider species diversity of the Chornomorskiy and Askania Nova Biosphere Reserves. A comprehensive sozological assessment of the areas proposed for protection, which already have detailed botanical descriptions, is expected. There is a high probability of extinction of a number of species from the above mentioned protected areas, since all the studied sites were affected by the hostilities.

Authors: Li Zhijun
Published: September 2024

Objective: To evaluate the therapeutic effect of using drug-coated balloon (DCB) during percutaneous coronary intervention (PCI) for unstable angina (UA). Methods: 97 patients with UA treated in the Twelfth People’s Hospital of Guangzhou between August 2019 and June 2023 were selected, all of whom underwent PCI. Random number table grouping, 49 cases in the experimental group were treated with DCB during the operation; 48 cases in the reference group were treated with drug-coated stent (DSE) implantation during the operation, comparing the cardiac function indexes, prognostic indexes, quality of life scores, and adverse cardiovascular events (MACE) in the 2 groups. Results: There was no difference in the cardiac function indexes between the two groups when comparing preoperative and 6 months postoperative (P > 0.05). In the immediate postoperative period and 1 year postoperatively, there was no difference in the comparison of reference vessel diameter (RVD) and minimum lumen diameter (MLD) between the two groups (P > 0.05); the level of late lumen loss in the experimental group was lower than that in the reference group (P < 0.05). Preoperatively, there was no difference in the comparison of quality of life scores between the two groups (P > 0.05). At 1 year postoperatively, the quality of life score of the experimental group was higher than that of the reference group (P < 0.05). The incidence of MACE in the experimental group was lower than that in the reference group (P < 0.05). Conclusion: The use of DCB therapy and DSE implantation in PCI can enhance the cardiac function of patients with UA, improve the levels of RVD and MLD, and prevent luminal restenosis, improve the postoperative quality of life, and have a high therapeutic safety.

Objective: This study aims to provide an accurate quantitative analysis of the burden of ischemic heart disease (IHD) in China, and to provide a scientific basis for the development of effective prevention and control strategies. Methods: Based on the latest public database GBD2021 (2021 Global Burden of Diseases), the characteristics and trends of incident, prevalence, death, and attributable risk factors of IHD in the Chinese population from 1990 to 2021 were quantitatively analyzed. Results: From 1990 to 2021, the burden of IHD in China has significantly increased. The number of incident cases increased from 23.01 million in 1990 to 70.40 million in 2021, with an annual growth rate of 3.97%. The number of prevalent cases increased from 195 million in 1990 to 633 million in 2021, with an annual growth rate of 3.92%. The number of deaths also showed an upward trend, increasing from 547,800 in 1990 to 1.9569 million in 2021, with an annual growth rate of 4.19%. The incidence rate increased from 195.64/100,000 in 1990 to 513.41/100,000 in 2021, with an annual growth rate of 3.36%. The prevalence rate increased from 1657.98/100,000 in 1990 to 4451.34/100,000 in 2021, with an annual growth rate of 3.31%. The mortality rate increased from 46.57/100,000 in 1990 to 137.54/100,000 in 2021, with an annual growth rate of 3.34%. The age-standardized incidence rate increased from 315.31/100,000 in 1990 to 365.67/100,000 in 2021, with an annual growth rate of 0.66%; the age-standardized prevalence rate increased from 2526.44/100,000 in 1990 to 3042.35/100,000 in 2021, with an annual growth rate of 0.64%; the age-standardized mortality rate increased from 94.14/100,000 in 1990 to 110.91/100,000 in 2021, with an annual growth rate of 0.72%. These data directly reflect the changing trend of the burden of IHD in China. Conclusion: The conclusion section indicates that from 1990 to 2021, the burden of IHD in China has significantly increased, manifested by the continuous rise in incident cases, prevalent cases, and deaths. The research data shows that the annual growth rates of incident cases, prevalent cases, and deaths due to IHD are 3.97%, 3.92%, and 4.19% respectively, reflecting the serious situation of prevention and control of IHD in China. In addition, although the growth rates of age-standardized incidence, prevalence, and mortality rates are relatively slow, they still show an overall upward trend, which may be related to factors such as population aging, lifestyle changes, and insufficient management of chronic diseases. These findings emphasize the urgency of taking effective prevention and control measures to reduce the impact of IHD on the public health system in China.
