Phase diagram of holographic thermal dense QCD matter with rotation
A
bstract
We study the rotation effects of the hot and dense QCD matter in a non-perturbative regime by the gauge/gravity duality. We use the gravitational model that is designated to match the state-of-the-art lattice data on the thermal properties of (2+1)-flavor QCD and predict the location of the critical endpoint and the first-order phase transition line at large baryon chemical potential without rotation. After introducing the angular velocity via a local Lorentz boost, we investigate the thermodynamic quantities for the system under rotation in a self-consistent way. We find that the critical temperature and baryon chemical potential associated with the QCD phase transition decrease as the angular velocity increases. Moreover, some interesting phenomena are observed near the critical endpoint. We then construct the 3-dimensional phase diagram of the QCD matter in terms of temperature, baryon chemical potential, and angular velocity. As a parallel investigation, we also consider the gravitational model of SU(3) pure gluon system, for which the 2-dimensional phase diagram associated with temperature and angular velocity has been predicted. The corresponding thermodynamic quantities with rotation are investigated.

LncRNA PVT1 regulates atrial fibrosis via miR-128-3p-SP1-TGF-β1-Smad axis in atrial fibrillation
Background
Long non-coding RNAs (lncRNA) plasmacytoma variant translocation 1 (PVT1) has been shown to be associated with liver fibrosis. Nevertheless, the role of PVT1 in atrial fibrosis remains undefined. This study aims to elucidate the pathophysiological role of lncRNA PVT1 in the regulation of atrial fibrosis and to explore the underlying mechanism.
Methods
Expression of PVT1, miR-128-sp, and Sp1 were examined in human atrial muscle tissues and angiotensin-II (Ang-II)-induced human atrial fibroblasts. Furthermore, the role of PVT1 in regulating atrial fibrosis in Ang-II-treated human atrial fibroblasts and Ang-II-induced atrial fibrosis in mice was investigated. Moreover, the interaction among PVT1, miR-128-3p, and Sp1 were examined using bioinformatics, expression correlation analysis, gain- or loss-of-function assays, RIP assays, and luciferase reporter assays. The involvement of transforming growth factor beta 1 (TGF-β1)/Smad pathway in this process was also explored.
Results
PVT1 was increased in atrial muscle tissues from AF patients and positively with collagen I and collagen III. In vitro assay revealed that PVT1 overexpression facilitated the Ang-II-induced atrial fibroblasts proliferation, collagen production, and TGF-β1/Smad signaling activation, whereas PVT1 knockdown caused the opposite effect. In vivo assay further confirmed that PVT1 knockdown attenuated the Ang-II-induced mouse atrial fibrosis. Mechanically, PVT1 acted as a sponge for miR-128-3p to facilitate Sp1 expression, thereby activating the TGF-β1/Smad signaling pathway.
Conclusion
LncRNA PVT1 promotes atrial fibrosis via miR-128-3p-SP1-TGF-β1-Smad axis in atrial fibrillation.

Vector meson spectral function in a dynamical AdS/QCD model
By using gauge/gravity duality, we calculate the spectral function of the heavy vector mesons with the presence of an intense magnetic field in a hot and dense medium. The results show that, a general conclusion, as the increases of magnetic field, chemical potential and temperature, the height of the peak of the spectral function decreases and the width increases. A nontrivial result is the change from the peak position of spectral function. We explain this non-trivial behavior by the interplay of the interaction between the two heavy quarks and the interaction between the medium with each of the heavy quarks.

Holographic spin alignment of J/ψ meson in magnetized plasma
A
bstract
We study the mass spectra and spin alignment of vector meson
J/ψ
in a thermal magnetized background using a generalized theoretical framework based on gauge/gravity duality. Utilizing a soft wall model for the QGP background and a massive vector field for the
J/ψ
meson, we delve into the meson’s spectral function and spin parameters (
λ
θ
, λ
φ
, λ
θφ
) for different cases, assessing their response to variations in magnetic field strength, momentum, and temperature. We initially examine scenarios where a meson’s momentum aligns parallel to the magnetic field in helicity frame. Our results reveal a magnetic field-induced positive
λ
θ
H
for low meson momentum, transitioning to negative with increased momentum. As a comparison, we also study the case of momentum perpendicular to the magnetic field and find the direction of magnetic field does not affect the qualitative behavior for the
eB
-dependence of
λ
θ
H
. Moreover, we apply our model to real heavy-ion collisions for three different spin quantization directions. Further comparisons with experimental data show qualitative agreement for spin parameters

J/Ψ suppression in a rotating magnetized holographic QGP matter
We study the dissociation effect of
J
/
Ψ
in magnetized, rotating QGP matter at finite temperature and chemical potential using gauge/gravity duality. By incorporating angular velocity into the holographic magnetic catalysis model, we analyze the influence of temperature, chemical potential, magnetic field, and angular velocity on the properties of
J
/
Ψ
meson. The results reveal that temperature, chemical potential, and rotation enhance the dissociation effect and increase the effective mass in the QGP phase. However, the magnetic field suppresses dissociation, and its effect on the effective mass is non-trivial. Additionally, we explore the interplay between magnetic field and rotation, identifying a critical angular velocity that determines the dominant effect. As a parallel study, we also examine the rotation effect in the holographic inverse magnetic catalysis model, although the magnetic field exhibits distinctly different behaviors in these two models, the impact of rotation on the dissociation effect of
J
/
Ψ
is similar. Finally, we investigate the influence of electric field and demonstrate that it also speeds up the
J
/
Ψ
dissociation.

Contemporary characteristics, management, and outcomes of patients hospitalized for atrial fibrillation in China: results from the real-world study of Chinese atrial fibrillation registry
[1] Indeed, most understanding of AF is based on findings from clinical trials and observational studies performed in North America and Western Europe,[2] and some studies have described the characteristics of patients with AF in other regions. [...]the aim of this study was to investigate the clinical demographics, management, and outcomes of patients hospitalized for AF using data from a recently registered AF-specific nationwide cohort study in China, the real-world study of Chinese atrial fibrillation (RWS-CAF) registry. The collected data included age, sex, type of AF, body mass index, valvular or non-valvular AF, hypertension, coronary heart disease (CHD), heart failure, diabetes mellitus (DM), chronic obstructive pulmonary disease (COPD), CHA2DS2-VASc score, and HAS-BLED (hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, drugs/alcohol concomitantly) score.

Effect of acupuncture on quality of life in atrial fibrillation: study protocol for a randomised controlled trial
IntroductionAtrial fibrillation (AF) is the prevalent cardiac arrhythmia and can significantly impair the quality of life (QoL). Although catheter ablation (CA) is an established treatment for AF,post-procedural complications or perceived inadequate control of AF may diminish the QoL for some patients, potentially even to levels lower than pre-procedure. Preliminary findings from our previous pilot trial indicate that acupuncture may positively influence QoL in AF patients post-CA. This study aims to increase the sample size to evaluate the efficacy of acupuncture as an adjunctive treatment to conventional medical therapy in improving QoL of patients with AF after CA.Methods and designThis multicentre randomised clinical trial will be conducted in China. A total of 146 eligible patients will be randomly assigned in a 1:1 ratio to either the acupuncture group or the sham acupuncture group. All patients will receive standard postablation care and undergo 18 sessions of acupuncture/sham acupuncture within 12 weeks following CA, followed by a 9-month follow-up period. The primary outcome is the change in the Atrial Fibrillation Effect on Quality-of-Life (AFEQT) summary score from baseline to months 6 after CA. Secondary outcomes include the changes in the AFEQT subscale scores at months 6, the AFEQT summary and subscale score at months 3 and 12, AF burden, AF recurrence, heart rate variability, number of cardioversions, repeat CA procedures, European Heart Rhythm Association score, number of arrhythmia-related hospitalisations, average heart rate, use of Six-Dimensional Health State Short Form to assess health status, costs incurred by disease treatment, Credibility/Expectancy Questionnaire and blinded assessments. Adverse events will also be meticulously recorded throughout the trial.Ethics and disseminationEthics approval has been granted by the Ethics Committee of Beijing University of Traditional Chinese Medicine (approval no: 2020BZYLL0802) and seven other subcentres. The findings of the study results will be disseminated through presentations at scientific conferences or publications in peer-reviewed journals.Trial registration numberChiCTR2100049323.

Bibliometric analysis of acupuncture research through the Web of Science database from 1990 to 2019
Background: The main points of focus of bibliometric analysis of acupuncture treatment of diseases include pain (headache, low back pain), insomnia, and knee osteoarthritis, for example. In this paper, we analyze the frontiers, hotspots, and research trends of acupuncture over the past 30 years and compare them for each of three 10-year periods. Methods: All the studies on acupuncture research in three different periods (1990–1999, 2000–2009, 2010–2019) were collected from the Web of Science database. The evolution of the research, hotspots, and trends in acupuncture were explored intuitively by analyzing the frequency, betweenness centrality, and subject word clustering of the three periods. Results: (1) 1990–1999, the main content relating to research was the mechanism of research of acupuncture treatment of pain. Naloxone was the high-frequency subject word, and centrality included, for example, the spinal cord, enkephalin, smoking cessation, and detoxification. The results of keyword cluster analysis showed that the main research content included capsaicin-induced neurogenic edema, chemical dependency treatment, afferent fiber, and sufferers from xerostomia. (2) 2000–2009, during this stage, the frequency of keywords appeared in new research content such as randomized controlled trials of acupuncture and low back pain, but pain still dominated the main research content. From the perspective of intermediary centrality, along with the rise in randomized controlled trials, there were many important meta-analyses, as well as the management of acupuncture treatment. The main elements of the keyword cluster analysis included, for example, systematic review, randomized controlled pilot study, add-on therapy, brief overview, and ovarian morphology. (3) 2010–2019, during this period, compared with the previous two stages, there was increased frequency of keywords, a growth in clinical randomized controlled trials, and distribution of centrality was evident in the emergence of acupuncture in care, osteoarthritis treatment, and breast cancer research. The keyword clustering covered, for example, neural specificity, inflammatory reaction, chronic pain, sleep pattern, and consort statement. Conclusion: This article summarizes the trend of development of acupuncture from 1990 to 2019 and compares the main research categories and hotspots in each of three different 10-year periods within this span, thereby helping elucidate the research direction within the field.
