Abstract
Purpose This study aimed to develop a novel and feasible modification strategy to improve the solubility and antitumor activity of resiquimod (R848) by utilizing the supramolecular effect of 2-hydroxypropyl-beta-cyclodextrin (2-HP-β-CD). Methods R848-loaded PLGA nanoparticles modified with 2-HP-β-CD (CD@R848@NPs) were synthesized using an enhanced emulsification solvent-evaporation technique. The nanoparticles were then characterized in vitro by several methods, such as scanning electron microscopy (SEM), differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) spectroscopy, particle size analysis, and zeta potential analysis. Then, the nanoparticles were loaded with IR-780 dye and imaged using an in vivo imaging device to evaluate their biodistribution. Additionally, the antitumor efficacy and underlying mechanism of CD@R848@NPs in combination with an anti-TNFR2 antibody were investigated using an MC-38 colon adenocarcinoma model in vivo. Results The average size of the CD@R848@NPs was 376 ± 30 nm, and the surface charge was 21 ± 1 mV. Through this design, the targeting ability of 2-HP-β-CD can be leveraged and R848 is delivered to tumor-supporting M2-like macrophages in an efficient and specific manner. Moreover, we used an anti-TNFR2 antibody to reduce the proportion of Tregs. Compared with plain PLGA nanoparticles or R848, CD@R848@NPs increased penetration in tumor tissues, dramatically reprogrammed M1-like macrophages, removed tumors and prolonged patient survival. Conclusion The new nanocapsule system is a promising strategy for targeting tumor, reprogramming tumor -associated macrophages, and enhancement immunotherapy.

Abstract
BACKGROUND This study aims to explore how miR-98-5p affects osteoarthritis, focusing on its role in chondrocyte inflammation, apoptosis, and extracellular matrix (ECM) degradation. METHODS Quantitative real-time PCR was used to measure miR-98-5p and CASP3 mRNA levels in OA cartilage tissues and IL-1β-treated CHON-001 cells. We predicted miR-98-5p and CASP3 binding sites using TargetScan and confirmed them via luciferase reporter assays. Chondrocyte viability was analyzed using CCK-8 assays, while pro-inflammatory cytokines (IL-1β, IL-6, TNF-α) were quantified via ELISA. Caspase-3 activity was examined to assess apoptosis, and Western blotting was conducted for protein marker quantification. RESULTS Our results showed lower miR-98-5p levels in both OA cartilage and IL-1β-stimulated cells. Increasing miR-98-5p resulted in reduced pro-inflammatory cytokines, decreased caspase-3 activity, and improved cell viability. Furthermore, miR-98-5p overexpression hindered IL-1β-induced ECM degradation, evident from the decline in MMP-13 and β-catenin levels, and an increase in COL2A1 expression. MiR-98-5p's impact on CASP3 mRNA directly influenced its expression. Mimicking miR-98-5p's effects, CASP3 knockdown also inhibited IL-1β-induced inflammation, apoptosis, and ECM degradation. In contrast, CASP3 overexpression negated the suppressive effects of miR-98-5p. CONCLUSIONS In conclusion, our data collectively suggest that miR-98-5p plays a protective role against IL-1β-induced damage in chondrocytes by targeting CASP3, highlighting its potential as a therapeutic target for OA.

Abstract
In this work, Pt3Fe nanoparticles (Pt3Fe NPs) with the ordered internal structure and Pt-rich shells surrounded by plenty of Fe single atoms (Fe SAs) as active species (Pt3Fe NP-in-Fe SA) loaded in the carbon materials are successfully fabricated, which are abbreviated as island-in-sea structured (IISS) Pt3Fe NP-in-Fe SA catalysts. Moreover, the synergistic effect of O-bridging between Pt3Fe NPs and Fe SAs, and the ordered internal structured Pt3Fe NPs with Pt-rich shells of an optimal thickness contributes to the achievement of the local acidic environments on the surfaces of Pt3Fe NPs in the alkaline hydrogen evolution reaction (HER) and the enhancement of the desorption rate of *OH intermediate in the acidic oxygen reduction reaction (ORR). In addition, the electronic interactions between Pt3Fe NPs and dispersed Fe SAs cannot only provide efficient electrons transfer, but also prevent the aggregation and dissolution of Pt3Fe NPs. Furthermore, the overpotential and the half wave potential of the as-prepared IISS Pt3Fe NP-in-Fe SA catalysts toward the alkaline HER and toward the acidic ORR are 8 mV at a current density of 10 mA cm-2 and 0.933 V, respectively, which is 29 lower and 86 mV higher than those (37 mV and 0.847 V) of commercial Pt/C catalysts.

Abstract
1. The following study addressed the problem of small duck eggs as challenging to detect and identify for pick up in complex free-range duck farm environments. It introduces improvements to the YOLOv4 convolutional neural network target detection algorithm, based on the working conditions of egg-picking robots.2. Specifically, one scale of anchor boxes was removed from the prediction network, and a duck egg labelling dataset was established to make the improved algorithm YOLOv4-ours better match the working state of egg-picking robots and enhance detection performance.3. Through multiple comparative experiments, the YOLOv4-ours object detection algorithm exhibited superior overall performance, achieving a precision of 98.85%, recall of 96.67%, and an average precision of 98.60% and F1 score increased to 97%. Compared to the original YOLOv4 model, these improvements represented increases of 1.89%, 3.41%, 1.32%, and 1.04%, respectively. Furthermore, detection time was reduced from 0.26 seconds per image to 0.20 seconds.4. The enhanced model accurately detected duck eggs in free-range duck housing, effectively meeting the real-time egg identification and picking requirements.

Abstract
BACKGROUND Previously, we revealed noticeable dynamic fluctuations in syndecan-1 levels in the peripheral blood of post-stroke patients. We further investigated the clinical prognostic value of syndecan-1 as a biomarker of glycoprotein damage in patients with acute ischaemic stroke (AIS). METHODS We examined 105 patients with acute large vessel occlusion in the anterior circulation, all of whom underwent mechanical thrombectomy (MT). Peripheral blood syndecan-1 levels were measured 1 day after MT, and patients were categorised into favourable and unfavourable prognostic groups based on the 90-day modified Rankin Scale (mRS) score. Additionally, we compared the clinical outcomes between groups with high and low syndecan-1 concentrations. RESULTS The findings revealed a significantly lower syndecan-1 level in the group with an unfavourable prognosis compared to those with a favourable prognosis (p < 0.01). In the multivariable logistic regression analysis, lower syndecan-1 levels were identified as a predictor of unfavourable prognosis (odds ratio (OR) = 0.965, p = 0.001). Patients displaying low syndecan-1 expression in the peripheral blood (< 29.51 ng/mL) experienced a > twofold increase in the rates of unfavourable prognosis and mortality. CONCLUSIONS Our study demonstrates that syndecan-1, as an emerging, easily detectable stroke biomarker, can predict the clinical outcomes of patients with AIS. After MT, low levels of syndecan-1 in the peripheral blood on the first day emerged as an independent risk factor for an unfavourable prognosis, suggesting that lower syndecan-1 levels might signify worse clinical presentation and outcomes in stroke patients undergoing this procedure.

Abstract
Liquefied petroleum gas (LPG) is widely used for its cleanliness and high efficiency in industry and city life. In order to improve the suppression effect on LPG explosion, a constant volume combustion bomb was used to investigate the synergistic influence of N2/ultrafine water mist on the explosion and combustion characteristics of 6% premixed LPG/air gas. The results showed that (1) the effect of a single ultrafine water mist on suppressing LPG explosion is unstable. When the concentration of ultrafine water mist is low, the flame acceleration in the initial stage of explosion is promoted, and when the ultrafine water mist with a mass fraction of 420 g/m3 is introduced, the maximum pressure rise rate increases. (2) The combination of N2/ultrafine water mist has a synergistic effect on LPG explosion. Compared to the individual suppression effects, the combination of N2/ultrafine water mist showed more effective suppression on the explosion pressure, flame propagation, and flame instability of LPG explosion. (3) Through the mechanism analysis, it is found that the combined action of N2/ ultrafine water mist can better reduce the mole fraction and ROP peak of active free radicals such as H, O, and OH by inhibiting the main reaction of generating H, O, and OH radicals during the explosion of LPG, resulting in the reduction of flame free radicals in the explosion system, thus effectively inhibiting the chain reaction of ignition and explosion of LPG. This research can provide guidance for a better understanding and implementation of gas-liquid two-phase suppression technology for LPG explosion.

Abstract
Background The gut microbiota (GM) is believed to be closely associated with symptomatic carotid atherosclerosis (SCAS), yet more evidence is needed to substantiate the significant role of GM in SCAS. This study, based on the detection of bacterial DNA in carotid plaques, explores the characteristics of GM in SCAS patients with plaque bacterial genetic material positivity, aiming to provide a reference for subsequent research. Methods We enrolled 27 healthy individuals (NHF group) and 23 SCAS patients (PFBS group). We utilized 16S rDNA V3-V4 region gene sequencing to analyze the microbiota in fecal samples from both groups, as well as in plaque samples from the carotid bifurcation extending to the origin of the internal carotid artery in all patients. Results Our results indicate significant differences in the gut microbiota (GM) between SCAS patients and healthy individuals. The detection rate of bacterial DNA in plaque samples was approximately 26%. Compared to patients with negative plaques (PRSOPWNP group), those with positive plaques (PRSOPWPP group) exhibited significant alterations in their GM, particularly an upregulation of 11 bacterial genera (such as Klebsiella and Streptococcus) in the gut, which were also present in the plaques. In terms of microbial gene function prediction, pathways such as Fluorobenzoate degradation were significantly upregulated in the GM of patients with positive plaques. Conclusion In summary, our study is the first to identify significant alterations in the gut microbiota of patients with positive plaques, providing crucial microbial evidence for further exploration of the pathogenesis of SCAS.

Abstract
Introduction: As psychoneuroimmunology flourishes, there is compelling evidence that depression suppresses the anti-tumor immune response, promotes the progression of cancer, and inhibits the effectiveness of cancer immunotherapy. Recent studies have reported that antidepressants can not only alleviate the depressant condition of cancer patients, but also strengthen the anti-tumor immunity, thus suppressing tumors. Tumor necrosis factor receptor 2 (TNFR2) antagonistic antibodies (Anti-TNFR2) targeting tumor-infiltrating regulatory T cells (Tregs) has achieved great results in preclinical studies, and with a favorable toxicity profile than existing immunotherapies, and is expected to become a new generation of more effective treatment strategies. Understanding the effects of combination therapy with antidepressants and Anti-TNFR2 may help design new strategies for cancer immunotherapy. Methods: We treated CT26, HCT116, MCA38 and SW620 colon cancer cells with fluoxetine (0-50 µM), ansofaxine hydrochloride (0-50 µM) and amitifadine hydrochloride (0-150 µM) to examine their effects on cell proliferation and apoptosis. We explored the antitumor effects of ansofaxine hydrochloride in combination with or without Anti-TNFR in subcutaneously transplanted CT26 cells in tumor-bearing mouse model. Antitumor effects were evaluated by tumor volume. NK cell, M1 macrophage cell, CD4+ T cell, CD8+ T cell, exhausted CD8+ T and regulatory T cell (Tregs) subtypes were measured by flow cytometry. 5-hydroxytryptamine, dopamine and norepinephrine levels were measured by ELISA. Results: Oral antidepression, ansofaxine hydrochloride, enhanced peripheral dopamine levels, promoted CD8+T cell proliferation, promoted intratumoral infiltration of M1 and NK cells, decreased the proportion of tumor-infiltrating exhausted CD8+T cells, and strengthened anti-tumor immunity, thereby inhibiting colon cancer growth. In combination therapy, oral administration of ansofaxine hydrochloride enhanced the efficacy of Anti-TNFR2, and produced long-term tumor control in with syngeneic colorectal tumor-bearing mice, which was attributable to the reduction in tumor-infiltrating Treg quantity and the recovery of CD8+ T cells function. Discussion: In summary, our data reveal the role of ansofaxine hydrochloride in modulating the anti-tumor immunity. Our results support that exhausted CD8+T is an important potential mechanism by which ansofaxine hydrochloride activates anti-tumor immunity and enhances anti-tumor effects of anti-TNFR2.

Abstract
The interfacial and confined water have long been attractive objects due to their crucial roles in biological, geological processes, etc. In this paper, we investigate the hydrogen-bonded structures of water and their low temperature transitions in the subnano channels of AlPO4-11 for the first time on the basis of infrared spectroscopy. The number of the adsorbed water molecules is estimated to be 8.45 per channel in one unit cell by thermogravimetric analysis. It is found that the confined water molecules are involved in saturated and unsaturated coordination with different hydrogen bond strengths at ambient temperature. The former refers to ice-like four-coordinated water and the latter includes liquid-like structures, Al-coordinated and relatively free water molecules. Unique coordination between water molecules and framework Al sites is responsible for the ice-like structures in the channels above the ice melting point. The appearance of liquid-like structures is closely related to the strong channel confinement, which does not allow the formation of extensive tetrahedral hydrogen-bonded configuration. As temperature decreases, a structural transformation of confined water happens in the channels of AlPO4-11. Isolated small water oligomers and two new components with stronger hydrogen bonds, such as low-density amorphous ice-like structures and a kind of low-density liquid-like structures are preferred. Our results provide important insights into the structural organizations and thermal-dynamic behaviors of confined water in extreme narrow channels.

Abstract
BACKGROUND Aspergillus infection seriously jeopardizes the health and safety of life of immunocompromised patients. The emergences of antifungal resistance highlight a demand to find new effective antifungal drugs. Angelica sinensis is a medicine-food herb and phthalides are its characteristic components. A few of the phthalides have been reported to display satisfactory antifungal activities against plant pathogenic fungi. However, the structure-activity relationships and antifungal action mechanism of phthalides remain to be further explored and elucidated. RESULTS The antifungal activities of five natural phthalides and four artificial analogs were investigated, and their structure-activity relationships were preliminarily elucidated in the current study. The benzene ring moiety played an essential role in their antifungal activities; the oxygen-containing substituents on the benzene ring obviously impacted their activities, the free hydroxyl was favorable to the activity. Typical phthalide senkyunolide B (SENB) exhibited broad antifungal activities against human and plant pathogenic fungi, especially, Aspergillus fumigatus. SENB affected the spore germination and hyphae growth of Aspergillus fumigatus via down-regulating phosphatidylinositol-PKC-calcineurin axis and the expression of ENG genes. Moreover, SENB disturbed the oxidation-reduction process in Aspergillus fumigatus to destroy the mature biofilms. In vivo experiments indicated SENB significantly prolonged survival and decreased fungal burden in mouse model of invasive pulmonary aspergillosis. CONCLUSIONS Phthalides could be considered as the valuable leads for the development of antifungal drug to cure plant and human disease. © 2023 Society of Chemical Industry.

Abstract
We employ the internally contracted multireference configuration interaction (icMRCI-F12) with Davidson corrections to explore the electronic states of monobromosilylene molecules (HSiBr). A total of 20 states with energy up to 8.7 eV and the corresponding 50 states after taking the spin-orbit coupling (SOC) effects into account are investigated. The spectroscopic constants of the low-lying states, as well as oscillator strengths, vertical transition energies and potential energy curves (PECs) for all the 20 spin-free states and the 50 spin-orbit-coupled states of HSiBr are presented. The results indicate that the SOC effect significantly affects the dissociation pathways and the PECs of electronic excited states of HSiBr. Based on our calculation results, the interactions between the states and the dissociation of HSiBr in the UV region are discussed. Our study sheds some light on the complex interactions and dynamics of the electronic excited states of HSiBr, which would provide valuable information for future experimental investigations.

Abstract
Four isoquinolinequinones (1-4) were isolated from the fermentation broth of Streptomyces albidoflavus which were derived from lichens. Among them, mansouramycin H (1) was identified as a new isoquinolinequinone by comprehensive spectroscopic data analysis. The mansouramycins from S. albidoflavus presented broad cytotoxic activities, especially against MDA-MB-231, but the SAR and mechanism were still unclear. The total synthesis of mansouramycin H (1) and its twenty-three derivatives were completed and their cytotoxic activities against MDA-MB-231 were evaluated in vitro. Primary SAR revealed that the piperazine moieties introduced into the amino group at C-7 could improve the activities of mansouramycins. Benzoyl and phenylacetyl groups on piperazine fragments had better activities than those of benzyl substitution; the alkyl substituent on piperazine exhibited optimal activity. Among them, compound 1g showed the strongest cytotoxicity against MBA-MB-231 cells with an IC50 value of 5.12 ± 0.11 μM. Mechanistic studies revealed that 1g induced apoptosis in MBA-MB-231 cells through down-regulating the protein expression of Bcl-2, up-regulating the protein expression of bax, and, meanwhile, activating the cleavage of caspase-3 and caspase-9. 1g caused S phase cell cycle arrest in MBA-MB-231 cells by reducing the protein expression of CDK2 and cyclin A2 and increasing the protein levels of p21.

Abstract
Introduction Social network strategies, in which social networks are utilized to influence individuals or communities, are increasingly being used to deliver human immunodeficiency virus (HIV) interventions to key populations. We summarized and critically assessed existing research on the effectiveness of social network strategies in promoting HIV self-testing (HIVST). Methods Using search terms related to social network interventions and HIVST, we searched five databases for trials published between January 1st, 2010, and June 30th, 2023. Outcomes included uptake of HIV testing, HIV seroconversion, and linkage to antiretroviral therapy (ART) or HIV Care. We used network meta-analysis to assess the uptake of HIV testing through social network strategies compared with control methods. A pairwise meta-analysis of studies with a comparison arm that reported outcomes was performed to assess relative risks (RR) and their corresponding 95% confidence intervals (CI). Results and discussion Among the 3,745 manuscripts identified, 33 studies fulfilled the inclusion criteria, including one quasi-experimental study, 17 RCTs and 15 observational studies. Networks HIVST testing was organized by peers (distributed to known peers, 15 studies), partners (distributed to their sexual partners, 10 studies), and peer educators (distributed to unknown peers, 8 studies). The results showed that all of the three social network distribution strategies enhanced the uptake of HIV testing compared to standard facility-based testing. Among social networks, peer distribution had the highest uptake of HIV testing (79% probability, SUCRA 0.92), followed by partner distribution (72% probability, SUCRA 0.71), and peer educator distribution (66% probability, SUCRA 0.29). Pairwise meta-analysis showed that peer distribution (RR 2.29, 95% CI 1.54-3.39, 5 studies) and partner distribution (RR 1.45, 95% CI 1.05-2.02, 7 studies) also increased the probability of detecting HIV reactivity during testing within the key population when compared to the control. Linkage to ART or HIV Care remained comparable to facility-based testing across the three HIVST distribution strategies. Conclusions Network-based HIVST distribution is considered effective in augmenting HIV testing rates and reaching marginalized populations compared to facility-based testing. These strategies can be integrated with the existing HIV care services, to fill the testing gap among key populations globally.PROSPERO Number: CRD42022361782.

Abstract
OBJECTIVE Metabolic biomarkers are expected to decode the phenotype of gastric cancer (GC) and lead to high-performance blood tests towards GC diagnosis and prognosis. We attempted to develop diagnostic and prognostic models for GC based on plasma metabolic information. DESIGN We conducted a large-scale, multicentre study comprising 1944 participants from 7 centres in retrospective cohort and 264 participants in prospective cohort. Discovery and verification phases of diagnostic and prognostic models were conducted in retrospective cohort through machine learning and Cox regression of plasma metabolic fingerprints (PMFs) obtained by nanoparticle-enhanced laser desorption/ionisation-mass spectrometry (NPELDI-MS). Furthermore, the developed diagnostic model was validated in prospective cohort by both NPELDI-MS and ultra-performance liquid chromatography-MS (UPLC-MS). RESULTS We demonstrated the high throughput, desirable reproducibility and limited centre-specific effects of PMFs obtained through NPELDI-MS. In retrospective cohort, we achieved diagnostic performance with areas under curves (AUCs) of 0.862-0.988 in the discovery (n=1157 from 5 centres) and independent external verification dataset (n=787 from another 2 centres), through 5 different machine learning of PMFs, including neural network, ridge regression, lasso regression, support vector machine and random forest. Further, a metabolic panel consisting of 21 metabolites was constructed and identified for GC diagnosis with AUCs of 0.921-0.971 and 0.907-0.940 in the discovery and verification dataset, respectively. In the prospective study (n=264 from lead centre), both NPELDI-MS and UPLC-MS were applied to detect and validate the metabolic panel, and the diagnostic AUCs were 0.855-0.918 and 0.856-0.916, respectively. Moreover, we constructed a prognosis scoring system for GC in retrospective cohort, which can effectively predict the survival of GC patients. CONCLUSION We developed and validated diagnostic and prognostic models for GC, which also contribute to advanced metabolic analysis towards diseases, including but not limited to GC.

Abstract
Background The treatment for Parkinson's disease (PD) consumes a lot of manpower and financial resources. Non-pharmacological alternative motor-/sensory-based interventions are optimized for the rehabilitation of PD patients. Mindfulness-based therapy shows ideal efficacy, but the diversity of the therapy brings difficulties to the selection of clinicians and patients. Methods Network meta-analysis in the Bayesian framework was used to evaluate the efficacy of non-pharmacological alternative motor-/sensory-based interventions in improving motor and non-motor symptoms in PD patients. Results A total of 58 studies (2,227 patients) were included. Compared with the non-intervention group, qigong was associated with improved outcomes in the Timed Up and Go (TUG) test (mean difference (MD) -5.54, 95% confidence interval (CI) -8.28 to -2.77), and UPDRS-I (MD -15.50, 95% CI -19.93 to -7.63). Differences between non-pharmacological alternative motor-/sensory-based interventions were not significant for PDQ-39, UPDRS-I, or UPDRS-II; however, qigong was superior to dance (MD -3.91, 95% CI -6.90 to -0.95), Tai Chi (MD -3.54, 95% CI -6.53 to -0.69), acupuncture (MD -6.75, 95% CI -10.86 to -2.70), music (MD -3.91, 95% CI -7.49 to -0.48), and exercise (MD -3.91, 95% CI -6.49 to -1.33) in the TUG test. Conclusion This network meta-analysis supports mindfulness-based therapy (e.g., qigong, yoga, and Tai Chi) as a preferred non-pharmacological alternative motor-/sensory-based intervention for PD rehabilitation.

Abstract
Grain boundary engineering is a versatile tool for strengthening materials by tuning the composition and bonding structure at the interface of neighboring crystallites, and this method holds special significance for materials composed of small nanograins where the ultimate strength is dominated by grain boundary instead of dislocation motion. Here, we report a large strengthening of a nanocolumnar copper film that comprises columnar nanograins embedded in a bamboo-like boron framework synthesized by magnetron sputtering co-deposition, reaching the high nanoindentation hardness of 10.8 GPa among copper alloys. The boron framework surrounding copper nanograins stabilizes and strengthens the nanocolumnar copper film under indentation, benefiting from the high strength of the amorphous boron framework and the constrained deformation of copper nanocolumns confined by the boron grain boundary. These findings open a new avenue for strengthening metals via construction of dual-phase nanocomposites comprising metal nanograins embedded in a strong and confining light-element grain boundary framework.

Abstract
Batch and column leaching tests were used to study thallium's release and migration behaviour and evaluate its potential toxicity risks in soil. The results indicated that leaching concentrations of Tl using TCLP and SWLP were much higher than the threshold, indicating a high risk of thallium pollution in the soil. Furthermore, the intermittent leaching rate of Tl by Ca2+ and HCl reached its maximum value, demonstrating the easy release of Tl. After HCl leaching, the form of Tl in the soil has changed, and ammonium sulfate has increased its extractability. Additionally, the extensive application of calcium promoted the release of Tl, increasing its potential ecological risk. Spectral analysis showed that Tl was mainly present in minerals such as Kaolinite and Jarosite, and exhibited significant adsorption capacity for Tl. HCl and Ca2+ damaged the crystal structure of the soil, greatly enhancing the migration and mobility of Tl in the environment. More importantly, XPS analysis confirmed that the release of Tl (I) in the soil was the leading cause of increased mobility and bioavailability. Therefore, the results revealed the risk of Tl release in the soil, providing theoretical guidance for its pollution prevention and control.

Abstract
A kind of high yield and recyclable Cobalt-Carbon composite (Zn1Co5/PnC) was prepared by carbothermal reduction process, in which the cobalt acetate and zinc acetate were considered as Zn and Co precursors, and the polyester waste was evolved as the carbon precursor. The morphology, structure and composition of the composite were characterized using scanning electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. Results showed that evaporation of zinc contributed to the formation of porous carbon structure, and the Co nanoparticles were wrapped and protected by the porous carbon matrix. The Zn1Co5/PnC activated peroxymonosulfate (PMS) system (Zn1Co5/PnC/PMS) was constructed to degrade the levofloxacin (LEV). The activity and mechanism of LEV degradation was understood. The LEV degradation efficiency was high to 96.60% within 90 min in the presence of Zn1Co5/P4C. Moreover, the Zn1Co5/P4C still maintained favorable PMS activation performance after five-cycle runs. The results show that the Zn1Co5/P4C played positive role in activating the PMS, it may be due to the facts that the polyester derived carbon could supported the Co while the evaporated Zn could increase the surface area of Zn1Co5/P4C, leading to the increased activity. The possible degradation pathways were proposed by identifying the intermediate products through liquid chromatography-mass spectrometry analysis. This study put forward a promising method to use polyester waste to synthesize high yield cobalt-carbon composite for degrading the antibiotic in wastewater.

Abstract
BACKGROUND Contrast-induced encephalopathy (CIE) is a rare transient, reversible abnormality in the structure or function of the nervous system caused by the intravascular use of contrast agents. CIE can present with a range of neurological manifestations, including focal neurological deficits (hemiplegia, hemianopia, cortical blindness, aphasia, and parkinsonism) and systemic symptoms (confusion, seizures, and coma). However, if not accurately diagnosed and treated in a timely manner, CIE can cause irreversible damage to patients, especially critically ill patients.
CASE SUMMARY A male in his 50 s, 2 h after digital subtraction angiography, had a progressive disorder of consciousness, mixed aphasia, bilateral pupillary sluggish light reflex, and right limb weakness. Seven hours after the procedure, he developed unconsciousness, high fever (39.5 °C), seizures, hemiplegia, neck stiffness (+), and right Babinski signs (+). computed tomography (CT) findings 2 h postprocedure were very confusing and led us to misdiagnose the patient with subarachnoid hemorrhage. Brain CT was performed again 7 h after the procedure. Compared with the CT 2 h after the procedure, the CT 7 h after the procedure showed that the manifestations of subarachnoid hemorrhage in the left cerebral hemisphere had disappeared and were replaced by brain tissue swelling, and the cerebral sulci had disappeared. Combined with the clinical manifestations of the patient and after the exclusion of subarachnoid hemorrhage and cerebrovascular embolism, we diagnosed the patient with CIE, and intravenous fluids were given for adequate hydration, as well as mannitol, albumin dehydration, furosemide and the glucocorticoid methylprednisolone. After 17 d of active treatment, the patient was discharged with no sequelae.
CONCLUSION CIE should be taken seriously, but it is easily misdiagnosed, and once CIE is diagnosed, rapid, accurate diagnosis and treatment are critical steps. Whether a follow-up examination using a contrast agent can be performed should be closely evaluated, and the patient should be fully informed of the associated risks.

Abstract
AIMS The increasing incidence of chronic kidney disease (CKD) urgently calls for effective nephroprotective agents. Traditional Chinese Medicine Angelica sinensis and its formula are well known for CKD therapy, but the underlying mechanisms and effective substances of reno-protective effects remain unclear. To this end, we isolated eleven ligustilide dimers (1-11) from A. sinensis and examined the molecular mechanism of their nephroprotective effects. MAIN METHODS Because of internal RAS playing an important role in CKD, we used renin expression as a target and screened preliminarily for antifibrotic effects of ligustilide dimers (1-11) by constructing a dual luciferase reporter gene in vitro. Furthermore, the reno-protective effects of the ligustilides and their underlying mechanism were investigated in TGF-β1-stimulated HK-2 cells and 5/6 nephrectomy (Nx) mice. KEY FINDINGS The ligustilide dimers exhibited anti-fibrotic effects by inhibiting human renin (hREN) promoter activity to decrease renin expression and down-regulate the expression of fibrosis-related factors, including α-SMA, collagen I, and fibronectin in vitro. Levistolide A (LA) and angeolide keto ester (AK) were screened out to identify their ability and underlying mechanism for treating CKD. Experimental validation further indicated that LA or AK treatment inhibited the expression of key molecules in RAS, TGF-β1/Smad, and MAPK pathways to downregulate ECM deposition. Furthermore, LA obviously meliorated renal injury in 5/6 Nx mice through ameliorating oxidant stress, inflammation, apoptosis and renal fibrosis. SIGNIFICANCE The experimental results demonstrated that ligustilide dimers were potential nephroprotective agents. LA might be an attractive drug candidate for renin-targeted CKD therapy.

Abstract
Arrhythmia is one of the common cardiovascular diseases. Nowadays, many methods identify arrhythmias from electrocardiograms (ECGs) by computer-aided systems. However, computer-aided systems could not identify arrhythmias effectively due to various the morphological change of abnormal ECG data. This paper proposes a deep method to classify ECG samples. Firstly, ECG features are extracted through continuous wavelet transform. Then, our method realizes the arrhythmia classification based on the new lightweight context transform blocks. The block is proposed by improving the linear content transform block by squeeze-and-excitation network and linear transformation. Finally, the proposed method is validated on the MIT-BIH arrhythmia database. The experimental results show that the proposed method can achieve a high accuracy on arrhythmia classification.

Abstract
PURPOSE The relationship of CAN and BMD, fracture risk is still unclear in T2DM. The aim of the present study is to investigate the correlation between heart rate variability (HRV) and BMD in T2DM. METHODS The study included 276 patients with T2DM aged ≥ 50 years, and Cardiovascular Autonomic Reflex Tests (CARTs) were applied to divide patients into two groups: CAN ( ±). 24 h Ambulatory ECG was assessed for HRV, BMD was measured by dual-energy X-ray bone densitometry, and FRAX scores were calculated for 10-year hip fracture risk (HF1) and major osteoporotic fracture risk (MOF). Adjusted regression analysis was performed to investigate influence factors for BMD and fracture risk. ROC curve was used to analyze the optimal cut-off point of LF/HF for screening osteoporosis. RESULTS Baseline data showed significant differences in the duration of T2DM, insulin resistance index (HOMA-IR), 25-hydroxyvitamin D[25(OH)D], femoral neck BMD, hip BMD, lumbar BMD, HF1, and MOF between the CAN ( +) and CAN (-) groups. The proportion of patients with osteoporosis increased as the degree of CAN lesion increased. Correlation analysis showed that LF/HF was significantly correlated with BMD, especially with hip (r = - 0.534, p < 0.001). Regression analysis showed that LF/HF was a risk factor for reduced BMD and increased fracture risk. The optimal cut-point value for LF/HF to predict osteoporosis by ROC curve analysis was 3.17. CONCLUSIONS CAN is associated with reduced BMD and increased fracture risk in patients with T2DM, and LF/HF may have the potential to be a predictor of diabetic osteoporosis and have some clinical value in early diagnosis of diabetic osteoporosis and non-traumatic fractures in T2DM.

Abstract
Lead-containing sludge produced from lead-acid battery factory will cause environmental hazards if they are not treated properly. A novel process was developed to recycle lead from sludge back into Fe-doped PbO2 electrodes and realize sludge reduction in this study. The effects of Fenton conditioning on Pb removal efficiency in electro-kinetic (EK) treatment process and its mechanism as well as electro-dewatering (ED) performance were investigated. It was found that the oxidation of Fenton can promote desorption and release of Pb from the organic binding state, and improve the removal efficiency of Pb during EK process, as well as enhance sludge ED performance. About 63.8 wt% Pb can be removed from sludge during EK process, achieving sludge reduction of 63.5 wt% by ED treatment. The composite PbO2@Fe electrode recovered from lead-containing sludge showed a high electrocatalytic activity for acid red G (ARG) degradation. The electrode obtained by electrodeposition at 20 mA cm-2 had the largest exchange current density (3.26 × 10-5 A cm-2). In the experiment of dye wastewater electrocatalytic degradation, over 99.5% organic matter was degraded within 80 min.

Abstract
Although the precise pathogenesis of steroid-induced osteonecrosis of femoral head (SONFH) is not yet fully understood, evidence shows miRNAs-mediated posttranscription control directs the adipogenesis of bone marrow mesenchymal stem cells (BMSCs) and plays a pivotal role in the SONFH processes. Huogu injection formulated according to traditional Chinese medicine (TCM) theory has been used to treat SONFH by intra-articular injection. In this study, we asked whether the therapeutic effects of Huogu injection might depend on the inhibition of adipogenic differentiation of BMSCs, and if so, the pathway might be a therapeutic target to promote bone repair. Consequently, miR-34c-5p was upregulated in the dexamethasone (DEX)-treated BMSCs and might participate in the adipogenesis of BMSCs. TargetScan database and the luciferase reporter assay showed miR-34c-5p targeted on the MDM4 and negatively regulated its expression. Huogu injection in vitro inhibited the adipogenesis in the DEX-treated BMSCs by inhibiting the expression levels of PPARγ and C/EBPα, as well as reducing miR-34c-5p to prevent the degradation of MDM4. Moreover, miR-34c-5p mimic or MDM4 knockdown using shRNA neutralized the anti-adipogenesis of Huogu injection in BMSCs. In vivo, the results of X-ray imaging confirmed that Huogu injection alleviated the bone loss in rat SONFH. Consistent with results in vitro, Huogu injection reduced the lipid accumulation, removed the suppression of MDM4 by downregulating the expression of miR-34c-5p, and inhibited the expression of C/EBPα and PPARγ in bone tissues. When the lentivirus encoding miR-34c-5p was conducted by intra-articular injection, the overexpression of miR-34c-5p antagonized the therapeutic effects of Huogu injection. Our results underline the critical importance of the miR-34c-5p/MDM4 pathway in regulating the adipogenic outcome of BMSCs, suggesting the miR-34c-5p as a potentially effective therapeutic target in SONFH. These results further reinforce the potential of Huogu injection as an alternative approach in SONFH.

Abstract
OBJECTIVE The current study aimed to assess the reporting quality of the clinical practice guidelines/consensuses on metastatic colorectal cancer based on the Reporting Items for Practice Guidelines in HealThcare (RIGHT) checklist. METHODS We searched China National Knowledge Infrastructure, VIP database, Wanfang Data, Chinese Biological Literature Service System, PubMed, Web of Science, ScienceDirect, Elsevier clinicalkey, BMJ Database, EMBASE, Cochrane Library, World Health Organization Network and other websites. We collected clinical practice guidelines/consensuses on metastatic colorectal cancer with published between 1 January 2017 and 1 April 2021 after release of the RIGHT checklist. Two reviewers extracted the basic information independently and conducted a RIGHT evaluation. RESULTS Eighteen guidelines/consensuses were included, 10 from China and 8 from other countries. The average reporting rate was 74.1%±11.2%. Thirteen items had 100% reporting rate, and the reporting rate for items No. 16 (11.1%), 17 (16.7%) and 18b (22.2%) was low. Basic information had the highest reporting rate (100%), whereas review and quality assurance had the lowest (13.9%). The average reporting rate of guidelines/consensuses published in other countries was higher than in China [p=0.005; odds ration (OR) 1.17, 95% confidence interval (CI) 1.07-1.28]. The average reporting rate of the guidelines was higher than that of the consensus statements (p<0.001; OR 1.20, 95% CI 1.10-1.31). The reporting rates of guidelines/consensuses focused on whole body (79.0%±12.7%) were higher than local organ (69.2%±7.3%) metastases (p=0.005; OR 1.14, 95% CI 1.04-1.25). CONCLUSIONS The quality of reporting using the RIGHT checklist varied among the guidelines/consensuses on metastatic colorectal cancer. Low-quality items were external review and quality assurance. Developers of guidelines/consensuses should aim to improve the reporting quality in the future.

Abstract
Background and purpose Acupuncture is widely used in clinical practice for the treatment of vascular diseases. However, the protocol, efficacy, and mechanism of acupuncture in animal models of vascular dementia are still controversial. Based on the above problems, we initiated this comprehensive study. Methods To analyze the literatures included in this study, 4 databases were searched and the SYRCLE's Risk of bias tool was employed. To perform the subgroup analysis of different acupuncture methods and the Review Manager 5.3 was applied. Meanwhile, the pairwise and network meta-analysis were conducted using Addis 1.16.8. The outcomes included escape latency, number of crossings, time spent in the target quadrant, and swimming speed. Results Forty-two studies with a total of 1,486 animals were included in this meta-analysis. According to the results from subgroup analysis, GV20 + ST36 (Baihui + bilateral Zusanli) combined with 14-day manual acupuncture can obtain best improvement of the rats cognitive function among all acupuncture regimens (MD: -23.41; 95%CI: -26.66, -20.15; I2 = 0%; P < 0.001). The heterogeneity of other acupuncture treatments was significantly higher than that of GV20 + ST36, because the treatment courses were not uniform. Pair-wise and network comparisons are highly consistent. The major results of the network meta-analysis were as follows, In comparison to the impaired group, the acupuncture group showed significantly reduced escape latency (MD: -25.87; 95%CI: -30.75, -21.12), increased number of original platform crossings (MD: 2.63; 95%CI: 1.94, 3.34) and time spent in the target quadrant (MD: 7.88; 95%CI: 4.25, 11.44). The overall results of the network meta-analysis are as follows: the normal and sham-operated groups performed the best, followed by medicine and acupuncture, while no effect was found in the impaired group treated with non-acupoint and palliative. Conclusions Acupuncture significantly improves cognitive function in rats with vascular dementia. Compared to other acupuncture plans, (GV20 + ST36, MA) and 14 -day manual acupuncture can be used to obtain better results. The main mechanism of acupuncture in the treatment of vascular dementia is reduced oxidative stress, neuronal inflammation, and apoptosis, as well as the increased synaptic plasticity and neurotransmitters.

Abstract
ABSTRACT Food additives are widespread in the human diet; however, their excessive intake can have an impact on the quality of health. This study evaluated food additives in bread and pasta products consumed by residents in various regions of Jilin Province, People's Republic of China, from 2019 to 2021. We collected samples of bread and six types of pasta products from farmers' markets and morning markets and used high-performance liquid chromatography, UV-visible spectrophotometry, and graphite furnace atomic absorption spectrometry to detect the content of the following food additives: sodium formaldehyde sulfoxylate, aluminum, and borate compounds. For 836 samples in total, we detected the presence of sodium formaldehyde sulfoxylate, aluminum, and borate compounds in excess rates reaching 3.5, 10, and 4.7%, respectively. Aluminum in fried breadsticks exceeded the standard by 40%. The results of this study can be used to assess the overall pass rate of bread and pasta products sold in Jilin Province and support the detection of possible food safety problems. HIGHLIGHTS

Abstract
BACKGROUND We report a hitherto unreported combination of pulmonary stenosis, single coronary artery anomaly and coronary sinus to left atrial communication. Our case highlights the important value of coronary computed tomographic angiography and transthoracic echocardiography for the diagnosis of such anomalies and guidance for proper management. METHODS AND RESULTS A 64-year-old male presented chest tightness and shortness of breath for 2 days. Transthoracic echocardiography revealed a thickened pulmonary valve leaflet and subvalvular outflow tract stenosis, colour flow Doppler showed a significant accelerated blood flow in the pulmonary artery cavity originating from the subvalvular outflow tract, continuous wave Doppler revealed the transpulmonary valvular pressure gradient of 63mmHg. Computed tomographic angiography image reveals thickened pulmonary valve leaflets and subvalvular outflow tract stenosis, single coronary artery anomaly and levoatriocardinal vein. The patient underwent percutaneous pulmonary valve balloon dilatation, the post-procedural course was uneventful. DISCUSSION Pulmonary stenosis can occur as part of more congenital cardiac malformations or as rare primary isolated pulmonary stenosis, which includes the valvular, sub-valvular, or supra-valvular pulmonary stenosis. Single coronary artery anomalies are very rare, anomalous right coronary artery originates from proximal to mid-left anterior descending coronary artery is one such single coronary artery anomaly, in most cases, it is asymptomatic, diagnosed incidentally, and a benign entity has a better prognosis except if the right coronary artery is passing between the aorta and pulmonary artery. This course of the right coronary artery anomaly is malignant. Coronary sinus to left atrial communication includes a direct or indirect communication. The direct communication is described as a partial or complete absence of the roof between the coronary sinus and left atrium, as it is well known as the unroofed coronary sinus syndrome. The indirect communication is an anomalous bridging vein communicating the coronary sinus to the left atrium, which can be distinguished from classical unroofed coronary sinus syndrome. The venous collateral channel communication between the coronary sinus to the left atrium by a bridging vein is also categorized as a variant type of unroofed coronary sinus syndrome. Understanding coronary venous variations has significant clinical implications particularly in the realm of electrophysiology. The anatomical variations can have important consequences for procedures such as biventricular pacing and trans-coronary vein ablations. CONCLUSION Pulmonary stenosis combined with single coronary artery anomaly and bridging vein communication between the coronary sinus and the left atrium is an extremely rare. Coronary computed tomographic angiography and transthoracic echocardiographyplay an important role the diagnosis of such anomalies and guidance for clinical Treatment.

Abstract
We perform time-resolved polarization-dependent study on ultrafast dynamics in the à 2 B 2 state of NO 2 . A linearly-polarized 400 nm femtosecond laser is used to resonantly pump NO 2 to its first excited state à 2 B 2 , and the time-dependent ionic yields produced via strong field ionization at 800 nm are measured under different laser polarizations. The yield ratios measured with the lasers perpendicular and parallel to each other first decrease then increase as the wave packet evolves on the excited state, with a minimum ratio at the delay time of 180 fs, which can be attributed to the evolution time in the à 2 B 2 state. The behavior of the time-resolved ionization in elliptically polarized laser field is also investigated and discussed. Our study indicates that the time-resolved polarization-dependent studies will shed some light on and pave the way to understand ultrafast dynamics in molecular excited states.

Abstract
Objective Chronic heavy drinking causes ethanol‐induced osteoporosis (EIO). The present study aimed to explore the role of GM in EIO. Material and Methods A rat EIO model was established by chronic ethanol intake. Taking the antibiotic application as the matched group of dysbacteriosis, an integrated 16S rRNA sequencing and liquid chromatography–tandem mass spectrometry‐based metabolomics in serum and faeces were applied to explore the association of differential metabolic phenotypes and screen out the candidate metabolites detrimental to ossification. The colon organoids were used to track the source of 5‐HT and the effect of 5‐HT on bone formation was examined in vitro. Results Compared with antibiotics application, ethanol‐gavaged decreased the BMD in rats. We found that both ethanol and antibiotic intake affected the composition of GM, but ethanol intake increased the ratio of Firmicutes to Bacteroidetes. Elevated serotonin was proved to be positively correlated with the changes of the composition of GM and faecal metabolites and inhibited the proliferation and mineralization of osteogenesis‐related cells. However, the direct secretory promotion of serotonin was absent in the colon organoids exposed to ethanol. Conclusion This study demonstrated that ethanol consumption led to osteoporosis and intestinal‐specific dysbacteriosis. Conjoint analysis of the genetic profiles of GM and metabolic phenotypes in serum and faeces allowed us to understand the endogenous metabolite, 5‐HT, as detrimental regulators in the gut‐bone axis to impair bone formation.

Abstract
A new bacterial strain, Acinetobacter calcoaceticus TY1, was identified in activated sludge. This strain efficiently metabolized nitrogen from ammonium at low temperatures, utilizing NH4+-N, NO3--N, and NO2--N as nitrogen sources. Of these, NH4+-N was superior in terms of both assimilation and heterotrophic nitrification at 8 °C. The nitrogen metabolism-associated genes amoA, nirK, and nosZ were identified in TY1. Optimal requirements for growth and nitrogen removal were pH 7, shaking speed of 90 rpm, a C/N ratio of 10, and sodium citrate for the carbon supply. The ability to denitrify at low temperature suggests TY1's potential for wastewater management.

Abstract
Activated persulfate oxidation has been proven to be an efficient advanced sludge treatment technique to improve sludge dewaterability. This study investigates the influence of persulfate on the transformation of phosphorus (P) and heavy metals (HMs) during the hydrothermal treatment of sewage sludge. The hydrothermal temperature, time, and persulfate concentration are optimized by a Box-Behnken design to obtain the best sludge dewaterability, which is expressed by capillary suction time (CST). The highest CST reduction efficiency is 90.5% at the optimal hydrothermal temperature, time, and concentration of persulfate, which are 145 °C, 2 h, and 150 mg/g dry sludge (DS), respectively. The distribution and transformation of P and HMs with different persulfate concentrations (100-200 mg/g DS) during the hydrothermal process are investigated. Results show that more than 90% of the P and HMs in the sludge are retained in sludge cakes after the hydrothermal treatment. The addition of SPS can make the P in the sludge cakes transform into more stable P species according to the extraction capacity of sequential extracts. It can be found from the ecological risk indexes of the HMs that the addition of SPS during the hydrothermal treatment of sludge can reduce the environmental risk of HMs. This study provides insights into the P and HM distribution and transformation during hydrothermal treatment with persulfate, providing a reference for sludge recovery strategies.

Abstract
BACKGROUND Left atrial anomalous fibromuscular cord is a rare congenital anomaly, which exists in a small proportion of the general population. Although its clinical significance remains largely unknown, it is generally considered a benign entity. We report a case of incidental finding of left atrial fibromuscular cord without structural cardiac abnormalities or hemodynamic obstruction. METHODS AND RESULTS A-39-year-old female presented with palpitations for more than 10 years. Electrocardiogram and laboratory tests showed no unremarkable. Transthoracic echocardiography revealed an abnormal linear structure connecting the interatrial septum and the left atrial free wall, color Doppler flow imaging did not show hemodynamic obstruction. Cardiac contrast-enhanced computed tomography images showed the string-like structure associated with calcification, connecting the interatrial septum and the ridge around the orifice of the left inferior pulmonary vein. Sagittal multiplanar reconstructed image showed a dot-like structure located in the left atrial cavity. DISCUSSION Left atrial anomalous fibromuscular cord is a rare congenital anomaly, which is also known as left atrial anomalous fibromuscular cord, left atrial false tendon, accessory chordae tendineae, or left atrial aberrant band. The clinical significance is unclear. Some cases have been reported that the fibromuscular cord, which do not have pathological significance. It has also been reported that it may be associated with supraventricular arrhythmias, patent foramen ovale, and Chiai's network. In some patients, attachment to the mitral chord can lead to mitral valve insufficiency and murmur. Nevertheless, a detailed understanding the anomalous anatomical characteristics of the anomalous cord may help us to better predict an unexpected difficulty in catheter manipulation, and potential arrhythmogenicity. CONCLUSION Transthoracic echocardiography and cardiac computed tomography angiography have an important imaging value for the diagnosis of the left atrial anomalous fibromuscular cord, including its origin, course, or whether associated with other cardiovascular malformations.

Abstract
BACKGROUND Abscess of the mitral-aortic intervalvular fibrosa (MAIVF) is a rare occurrence, with its most frequently described causative associations being active or prior endocarditis, prosthetic valves, or native valves with anomalies. We report a case of infective endocarditis (IE) complicated by an abscess of the MAIVF without valvular involvement. This case highlights the importance of this rare clinical entity and of the multimodality imaging approach in reaching an accurate diagnosis and differential diagnosis. METHODS AND RESULTS A 35-year-old male presented with fatigue and intermittent high-grade fever for a 2-week duration. IE was suspected based on a clinical exam. Transthoracic echocardiography (TTE) demonstrated heterogeneous mass with a size of about 2.9 cm × 2.3 cm coming from the MAIVF, mimicking an intracardiac mass. Color Doppler flow Imaging showed the mass without communication with the surrounding cardiovascular cavities. Cardiac computed tomography angiography (CCTA) revealed a large low-density mass without any enhancement, which was situated adjacent to the left ventricular tract with a severely compressed left atrial chamber. The patient underwent cardiac mass removal under extracorporeal circulation. During the procedure, a large abscess was found to be located in MAIVF. The postoperative course was uneventful. DISCUSSION The abscess of MAIVF is a rare entity with a high risk of developing the pseudoaneurysm of MAIVF (p-MAIVF). The periaortic spread of the abscess is a dynamic process in which the inflammation of the deep tissue causes, in the first stage, a MAIVF thickening, which eventually progresses with the formation of an abscess, and subsequently, a pseudoaneurysm. Complications of p-MAIVF include rupture into the left atrium, aorta, or pericardial space leading to hemopericardium, tamponade, and death. The major differential diagnosis for abscess of MAIVF includes p-MAIVF an intracardiac mass. TTE plays a key role in the diagnosis and differential diagnosis of abscesses of MAIVF. CCTA can be a useful adjunct to further characterize abscess spread, three-dimensional spatial relationships with other cardiac structures for preoperative planning, as well as in the evaluation of potential complications such as coronary artery compromise and communication with the aorta, left atrium, or pericardial space. Surgical management is recommended in complicated, symptomatic patients to prevent further expansion of abscesses or pseudoaneurysms. CONCLUSION The abscess of MAIVF is a rare complication of endocarditis and surgical trauma in the MAIVF area, TTE remains a first-line imaging modality for clinically suspected periaortic abscess or other IE complications. CCTA has a complementary role to echocardiography in identification, characterization, and preoperative planning.

Abstract
Background The use of transcranial magnetic stimulation combined with electromyography for the functional evaluation of the cerebral cortex in both clinical and non-clinical populations is becoming increasingly common. Numerous studies have shown that electro-acupuncture (EA) can regulate cerebral cortical excitability. However, the effect of EA on the lateralization of the human swallowing motor cortex excitability is not yet fully understood. Objective The aim of this study was to assess whether lateralization is present in the swallowing motor cortex of healthy subjects, and to investigate the impact of EA at Lianquan (CV23) and Fengfu (GV16) on lateralization. Methods Forty subjects were randomized 1:1 into the EA group and the sham-EA group. The bilateral swallowing motor cortices was located by a neuroimaging navigation system. Then, the resting motor threshold (RMT) and motor evoked potential (MEP) of the mylohyoid of healthy subjects were recorded while applying combined transcranial magnetic stimulation and electromyography before and after EA or sham-EA. Results First, the RMT and MEP latency of the contralateral mylohyoid innervated by the right swallowing cortex (71.50 ± 1.67%, 8.30 ± 0.06 ms) were lower than those innervated by the left (79.38 ± 1.27%, 8.40 ± 0.06 ms). Second, EA at CV23 and GV16 reduced the bilateral RMT and enhanced the bilateral MEP latency and amplitude (P = 0.005, P < 0.001; P = 0.002, P = 0.001; P = 0.002, P = 0.009), while sham-EA did not (P > 0.05). Third, EA had an effect on the RMT and MEP latency in terms of lateralization changes, but this was not significant (P = 0.067, P = 0.156). Conclusion The right swallowing motor cortex of healthy subjects is more excitable than that of the left at resting state. Thus, we found that lateralization is present in the swallowing motor cortex of healthy people, which might indicate a hemispheric dominance of swallowing predominates in the right swallowing motor cortex. In addition, EA at CV23 and GV16 can instantly promote the excitability of the bilateral swallowing motor cortices. But there was no significant difference in EA stimulation in terms of lateralization.

Abstract
BACKGROUND Abnormalities in drainage of the great cardiac vein (GCV) are interesting due to its rarity and likely to be underreported, with most cases found incidentally in cardiac imaging and autopsy studies. We report a case with anomalous drainage of the GCV into the LA, and the rest of the cardiac veins are draining normally. METHODS AND RESULTS A 60-year-old male presented with heart palpitations for half a month. Electrocardiogram and laboratory tests showed no abnormalities. He was recommended for coronary computed tomography angiography (CCTA). The maximum intensity projection image of CCTA showed that the GCV draining into the left atrium, the rest of the cardiac veins, and coronary vein sinus were draining into the right atrium normally. Volume-rendered image of coronary CT angiography showed that the GCV originated in the upper third of the anterior interventricular sulcus and drained directly into the left atrium. DISCUSSION Abnormalities in drainage of the GCV are interesting due to its rarity and likely to be underreported. Only a few cases have been reported that the aberrant drainage of the GCV, with draining into the anterior cardiac veins, the left internal thoracic vein, the superior vena cava, the right atrium, and the LA. The abnormality of GCV is an often neglected aspect of CCTA imaging, it can be better displayed in the venous phase of coronary catheter angiography. The awareness of which may be critically important for procedures that require venous access such as coronary surgery requiring retrograde cardioplegia, surgical ablation of aberrant conducting pathways, pacemaker insertion, and valves surgery. CONCLUSION This variant of the GCV is interesting due to its rarity. CCTA has important diagnostic imaging value in abnormalities of the origin, course, and termination of the GCVs, the variant can be better displayed in the venous phase of coronary catheter angiography.
