Abstract: Using 10.1 fb$^{-1}$ of $e^+e^-$ collision data collected by the BESIII detector with center-of-mass energies between 4.15 GeV and 4.30 GeV, we search for the decays $X(3872)\to\pi^0\pi^0\chi_{c1,2}$, where the $X(3872)$ is produced in $e^+e^-\to\gamma X(3872)$. No evidence above $3\sigma$ is found for either decay. Upper limits at the $90\%$ C.L. on the branching fractions of $X(3872)\to\pi^0\pi^0\chi_{c1,2}$ normalized to the branching fraction of $X(3872)\to\pi^+\pi^-J/\psi$ are set to be $\mathcal{B}(X(3872)\to\pi^0\pi^0\chi_{c1})/\mathcal{B}(X(3872)\to\pi^+\pi^-J/\psi) < 1.1$ and $\mathcal{B}(X(3872)\to\pi^0\pi^0\chi_{c2})/\mathcal{B}(X(3872)\to\pi^+\pi^-J/\psi) < 0.5$, taking into account both statistical and systematic uncertainties., Comment: 12 pages, 4 figures, 6 tables

Abstract: Based on a sample of $(2712.4\pm14.3)\times10^6\;\psi(3686)$ events collected with the BESIII detector, a partial wave analysis of the decay $\psi(3686)\to\Lambda\bar\Sigma^0\pi^0+c.c.$ is performed to investigate $\Lambda^*$ and $\Sigma^*$ resonances in the $\pi^0\bar{\Sigma}^0$ and $\pi^0\Lambda$ invariant mass distributions. Significant contributions are found from the $\Lambda(1405)$, $\Lambda(1520)$, $\Lambda(1600)$, $\Lambda(1670)$, $\Lambda(1690)$, $\Lambda(1800)$, $\Lambda(1890)$, $\Lambda(2325)$, $\Sigma(1385)$, $\Sigma(1660)$, $\Sigma(1670)$, $\Sigma(1750)$, and $\Sigma(1910)$. The masses, widths, and production branching fractions for each component are determined.

Abstract: By analyzing a data sample of $e^+e^-$ collisions with center-of-mass energy $\sqrt{s}=3.773$ GeV, corresponding to an integrated luminosity of $7.9~\rm {fb}^{-1}$ collected with the BESIII detector operating at the BEPCII collider, we study semileptonic decays of the $D^{0(+)}$ mesons into the axial-vector meson $b_1(1235)$ via the decay $b_1(1235)\to \omega\pi$. The decay $D^0\to b_1(1235)^-e^{+}\nu_{e}$ is observed with a significance of 5.2$\sigma$ after considering systematic uncertainty, while evidence for the decay $D^+\to b_1(1235)^0 e^+\nu_e$ is obtained with a 3.1$\sigma$ significance. The product branching fractions are determined to be ${\mathcal B}(D^0\to b_{1}(1235)^-e^{+}\nu_{e})\times {\mathcal B} (b_1(1235)^-\to \omega \pi^-) = (0.72\pm0.18^{+0.06}_{-0.08})\times10^{-4}$ and ${\mathcal B}(D^+\to b_{1}(1235)^0e^{+}\nu_{e})\times {\mathcal B} (b_1(1235)^0~\to \omega \pi^0) = (1.16\pm0.44\pm0.16)\times10^{-4}$, where the first uncertainties are statistical and the second systematic. The ratio of their partial decay widths is determined to be $\frac{\Gamma(D^0\to b_{1}(1235)^-e^{+}\nu_{e})}{2\Gamma(D^+\to b_{1}(1235)^0e^{+}\nu_{e})}=0.78\pm0.19^{+0.04}_{-0.05}$, which is consistent with unity, predicted by isospin invariance, within uncertainties., Comment: 9 pages, 2 figures

The measurements are carried out using several partial reconstruction techniques using data samples collected by the BESIII detector with a total integrated luminosity of 2.5~fb$^{-1}$. We search for new tetraquark candidates $Z_{cs}^\pm$ in the decays $Z_{cs}^\pm\to K^\pm\psi(2S)$. No significant $Z_{cs}^\pm$ signals are observed., Comment: 9 pages, 4 figures

Abstract: Using $(2.712\pm0.014)\times10^{9}$ $\psi(3686)$ events collected with the BESIII detector operating at the BEPCII, we find an evidence of the $\eta_{c}(2S)\to K^+ K^- \eta^{\prime}$ decay with a statistical significance of 3.1$\sigma$. Its decay branching fraction is measured to be $(12.24\pm4.60(\mathrm{stat.})\pm2.37(\mathrm{syst.})\pm4.68(\mathrm{extr.}))\times 10^{-4}$, where the first uncertainty is statistical, the second is systematic, and the third uncertainty is from the branching fraction of the $\psi(3686)\to\gamma\eta_{c}(2S)$ decay. The upper limit on the product branching fraction $B[\psi(3686)\to\gamma\eta_{c}(2S)] \times$ $B[\eta_{c}(2S)\to K^+ K^- \eta^{\prime}]$ is set to be $1.14 \times 10^{-6}$ at $90\%$ confidence level. In addition, the branching fractions of $\chi_{c1}\to K^+ K^- \eta^{\prime}$ and $\chi_{c2}\to K^+ K^- \eta^{\prime}$ are updated to be $(8.47\pm0.09(\mathrm{stat.})\pm0.47(\mathrm{syst.}))\times 10^{-4}$ and $(1.53\pm0.04(\mathrm{stat.})\pm0.08(\mathrm{syst.}))\times 10^{-4}$, respectively. The precision is improved by twofold.

Abstract: Based on $6.1~\mathrm{fb}^{-1}$ of $e^+e^-$ annihilation data collected at center-of-mass energies from 4.600~GeV to 4.843~GeV with the BESIII detector at the BEPCII collider, a partial wave analysis of $\Lambda_c^+\to\Lambda\pi^+\eta$ is performed, and branching fractions and decay asymmetry parameters of intermediate processes are determined. The process $\Lambda_c^+\to\Lambda a_0(980)^+$ is observed for the first time, and evidence for the pentaquark candidate $\Sigma(1380)^+$ decaying into $\Lambda\pi^+$ is found with statistical significance larger than $3\sigma$. The branching fraction product $\mathcal{B}(\Lambda_{c}^{+} \to \Lambda a_0(980)^+) \; \mathcal{B}( a_0(980)^+ \to \pi^{+}\eta)$ is determined to be $(1.05 \pm 0.16_{\mathrm{stat}} \pm 0.05_{\mathrm{syst}} \pm 0.07_{\mathrm{ext}})\%$, which is larger than theoretical calculations by $1 - 2$ orders of magnitude. Here the third (external) systematic is from $\mathcal{B}(\Lambda_{c}^{+} \to \Lambda \pi^+ \eta)$. Finally, we precisely obtain the absolute branching fraction $\mathcal{B}(\Lambda_{c}^{+} \to \Lambda \pi^+ \eta) = (1.94 \pm 0.07_{\mathrm{stat}} \pm 0.11_{\mathrm{syst}})\%$., Comment: 16 pages, 8 figures

Abstract: Based on $10.64~\mathrm{fb}^{-1}$ of $e^+e^-$ collision data taken at center-of-mass energies between 4.237 and 4.699 GeV with the BESIII detector, we study the leptonic $D^+_s$ decays using the $e^+e^-\to D^{*+}_{s} D^{*-}_{s}$ process. The branching fractions of $D_s^+\to\ell^+\nu_{\ell}\,(\ell=\mu,\tau)$ are measured to be $\mathcal{B}(D_s^+\to\mu^+\nu_\mu)=(0.547\pm0.026_{\rm stat}\pm0.016_{\rm syst})\%$ and $\mathcal{B}(D_s^+\to\tau^+\nu_\tau)=(5.60\pm0.16_{\rm stat}\pm0.20_{\rm syst})\%$, respectively. The product of the decay constant and Cabibbo-Kobayashi-Maskawa matrix element $|V_{cs}|$ is determined to be $f_{D_s^+}|V_{cs}|=(246.5\pm5.9_{\rm stat}\pm3.6_{\rm syst}\pm0.5_{\rm input})_{\mu\nu}~\mathrm{MeV}$ and $f_{D_s^+}|V_{cs}|=(252.7\pm3.6_{\rm stat}\pm4.5_{\rm syst}\pm0.6_{\rm input}))_{\tau \nu}~\mathrm{MeV}$, respectively. Taking the value of $|V_{cs}|$ from a global fit in the Standard Model, we obtain ${f_{D^+_s}}=(252.8\pm6.0_{\rm stat}\pm3.7_{\rm syst}\pm0.6_{\rm input})_{\mu\nu}$ MeV and ${f_{D^+_s}}=(259.2\pm3.6_{\rm stat}\pm4.5_{\rm syst}\pm0.6_{\rm input})_{\tau \nu}$ MeV, respectively. Conversely, taking the value for $f_{D_s^+}$ from the latest lattice quantum chromodynamics calculation, we obtain $|V_{cs}| =(0.986\pm0.023_{\rm stat}\pm0.014_{\rm syst}\pm0.003_{\rm input})_{\mu\nu}$ and $|V_{cs}| = (1.011\pm0.014_{\rm stat}\pm0.018_{\rm syst}\pm0.003_{\rm input})_{\tau \nu}$, respectively., Comment: 27 pages, 13 figures

Abstract: The $e^+e^-\rightarrow D_s^+D_{s1}(2536)^-$ and $e^+e^-\rightarrow D_s^+D^*_{s2}(2573)^-$ processes are studied using data samples collected with the BESIII detector at center-of-mass energies from 4.530 to 4.946~GeV. The absolute branching fractions of $D_{s1}(2536)^- \rightarrow \bar{D}^{*0}K^-$ and $D_{s2}^*(2573)^- \rightarrow \bar{D}^0K^-$ are measured for the first time to be $(35.9\pm 4.8\pm 3.5)\%$ and $(37.4\pm 3.1\pm 4.6)\%$, respectively. The measurements are in tension with predictions based on the assumption that the $D_{s1}(2536)$ and $D_{s2}^*(2573)$ are dominated by a bare $c\bar{s}$ component. The $e^+e^-\rightarrow D_s^+D_{s1}(2536)^-$ and $e^+e^-\rightarrow D_s^+D^*_{s2}(2573)^-$ cross sections are measured, and a resonant structure at around 4.6~GeV with a width of 50~MeV is observed for the first time with a statistical significance of $15\sigma$ in the $e^+e^-\rightarrow D_s^+D^*_{s2}(2573)^-$ process. It could be the $Y(4626)$ found by the Belle collaboration in the $D_s^+D_{s1}(2536)^{-}$ final state, since they have similar masses and widths. There is also evidence for a structure at around 4.75~GeV in both processes.

Abstract: A high precision measurement of the branching fraction of the decay $J/\psi \to p \bar{p} \eta$ is performed using $(10 087 \pm 44) \times 10^6$ $J/\psi$ events recorded by the {BESIII} detector at the {BEPCII} storage ring. The branching fractions of the two decays $J/\psi \to p \bar{p} \eta(\eta \to \gamma\gamma)$ and $J/\psi \to p \bar{p} \eta(\eta \to \pi^+ \pi^- \pi^0)$ are measured individually to be $\mathcal{B}(J/\psi \to p \bar{p} \eta(\eta \to \gamma\gamma)) = (1.480 \pm 0.001 \pm 0.024)\times\,10^{-3}$ and $\mathcal{B}(J/\psi \to p \bar{p} \eta(\eta \to \pi^+ \pi^- \pi^0)) = (1.557 \pm 0.003 \pm 0.038)\times\,10^{-3}$, where the first uncertainties are statistical and the second systematic. Both results are compatible within their uncorrelated systematic uncertainties. The combined result is $\mathcal{B}(J/\psi \to p \bar{p} \eta)=(1.495 \pm 0.001 \pm 0.023)\times\,10^{-3}$ where the first uncertainty is the combined statistical uncertainty and the second one the combined systematic uncertainty of both analyses, incorporating correlations between them. In addition, the $p \bar{p}$ threshold region is investigated for a potential threshold enhancement, and no evidence for one is observed.

However, reports on applying vibration therapy based on the holisitic theory of traditional Chinese medicine (TCM) remains limited. This study is to evaluate the immediate effect of vibration therapy on exercise-induced muscle fatigue.Methods: For this retrospective parallel controlled study, all data were from a previously approved and completed clinical trial. Participants (n=40) in the clinical trial included local Greco-Roman wrestling and Judo athletes in south China. The participants were equally randomly divided into the intervention group (n=20) and control group (n=20). The intervention group received a seven-week vibration intervention-based TCM holistic theory combined with conventional therapy, such as stretching, massage, and flapping, while the control group only received the conventional therapy. Surface electromyography (sEMG) of the lumbar segment of erector spinae was measured for each participant pre- and postintervention, and the two-point discrimination thresholds of the data were differentiated and compared with panel data analysis.Results: For the control group, the pre- and postintervention sEMG measure showed no significant difference (p=0.333), whereas significant difference (p=0.004) was observed for the intervention group. Further, the pre- and postintervention two-point discrimination test also showed a significant difference (p=0.016) for the intervention group.Discussion: The application of vibration therapy based on TCM holistic theory may have an immediate effect in reducing sport-induced muscle fatigue from intensive training. Future larger sample size and robust designed clinical trial is warranted to evaluate the long-term effect of the intervention.Keywords: holistic theory, traditional Chinese medicine, sport, muscle fatigue, vibration therapy

Therefore, it is particularly important to screen the predominant LUSC population using biomarkers.Methods: Data for 15 LUSC cell lines were downloaded from the Genomics of Drug Sensitivity in Cancer (GDSC) Project database to screen for mutations related to cisplatin susceptibility. We conducted whole-exome sequencing (WES) of tumors from 58 LUSC patients from Sichuan Provincial People’s Hospital of University of Electronic Science and Technology. Subsequently, the clinical prognostic value of these mutations was verified by using The Cancer Genome Atlas (TCGA)-LUSC cohort and our cohort (n=58).Results: Based on the cisplatin sensitivity data of GDSC-LUSC and survival analysis of TCGA-LUSC and Local-LUSC cohorts, we found that only mutation of IGF2R was associated with cisplatin sensitivity, better overall survival [OS; P=0.04, HR (95% CI): 0.42 (0.23– 0.78)] and progression-free survival [PFS; P =0.016, HR (95% CI): 0.26 (0.12– 0.59)]. However, there were no significant differences in the frequencies of gene mutations between the IGF2R-mutant (IGF2R-MT) and IGF2R-wild-type (IGF2R-WT) groups. Gene set enrichment analysis (GSEA) and single-sample GSEA (ssGSEA) indicated enhanced intracellular detoxification and decreased abnormal signaling activity to reverse cisplatin tolerance in the IGF2R-MT group.Conclusion: The results suggest that IGF2R mutations are a potential biomarker for screening LUSC patients suitable for cisplatin treatment.Keywords: cisplatin, lung squamous cell carcinoma, resistance, mutation, chemotherapy

In this project, we analyzed HCC tumor perfusion changes immediately after IRE treatment using transcatheter intraarterial perfusion (TRIP)-MRI to monitor treatment zone margins.Materials and Methods: All protocols were approved by the institutional animal care and use committee. A total of 34 rabbits were used for this prospective study: tumor liver group (n=17), normal liver group (n=14), and 3 for growing VX2 tumors. All procedures and imaging were performed under anesthesia. VX2 tumors were grown by injection of VX2 cells into rabbit hindlimbs. Liver tumors were induced by percutaneous US-guided injection of VX2 tumor fragments into liver. For digital subtraction angiography (DSA), a 2F catheter was advanced through left hepatic artery via femoral artery access, followed by contrast injection. All rabbits underwent baseline anatomic MRI, then IRE procedure or IRE probe placement only, and lastly post-procedure anatomic and TRIP-MRI. Liver tissues were dissected immediately after imaging for histology. All statistical analyses were performed on GraphPad Prism, with P< 0.05 considered significant.Results: IRE generated central IRE zone and peripheral reversible electroporation (RE) zone on anatomic MRI for both normal liver and liver tumor tissues. The semiquantitative analysis showed that IRE zone had the lowest AUC, PE, WIS, Ktrans, ve, and vp as well as the highest TTP, followed by RE zone, then untreated tissues. Receiver operating characteristic analysis showed that WIS and AUC60 had the highest AUCROC. Histologic analysis showed a positive correlation in viable area fraction between MRI and histologic measurements. IRE zone had the highest %apoptosis and lowest CD31+ staining.Conclusion: Our results demonstrated that intraprocedural TRIP-MRI can effectively differentiate IRE and RE zones after IRE ablation in normal liver and liver tumor tissues.Keywords: hepatocellular carcinoma, irreversible electroporation, liver cancer, perfusion, transcatheter intraarterial perfusion magnetic resonance imaging

The concurrent validity and internal consistency of the THINC-it test were analyzed, and 30 healthy controls were randomly sampled to retest THINC-it to verify the reliability of the THINC-it retest. The correlation between THINC-it and Hamilton Depression Scale (HAMD-17) and Sheehan Disability Scale (SDS) was also analyzed.Results: Fifty-eight patients with BD-D and 61 HCs were included for final analysis. There were significant mean difference (MD) standard errors (SE) between two groups in PDQ-5-D, Spotter and Codebreaker (all P< 0.01), Trails (P=0.015). There was no significant difference in Symbol Check (MD (SE)=− 0.01 (0.18), P=0.938; 95% CI=− 0.38 to 0.35). The Cronbach’s α of PDQ-5-D was 0.640. The intraclass correlation coefficient (ICC) was between 0.440 and 0.757. The highest concurrent validity was PDQ-5-D (r=0.812, P< 0.001). PDQ-5-D was positively correlated with HAMD-17 and SDS score (P< 0.01). The objective test had no significant correlation with HAMD-17 and SDS scores (P> 0.05).Conclusion: This study found that THINC-it can accurately present the cognitive impairment of patients with BD-D. It can be potentially applied in assessing the cognitive function of patients with BD-D although Symbol Check may not accurately reflect the level of cognitive function. The concurrent validity and retest reliability are lower than expected, we need to further increase the sample size to study.Keywords: bipolar depression, BD-D, major depressive depression, MDD, THINC-it, cognitive function, reliability, validity

Fat homeostasis is essentially maintained by fat accumulation and energy expenditure. Studies on brown adipose tissue (BAT) represent a promising opportunity to identify a pharmaceutical intervention against obesity through increased energy expenditure. Long non-coding RNAs (lncRNAs) were thought to be critical regulators in a variety of biological processes. Recent studies have revealed that lncRNAs, including ones that are BAT-specific, conserved, and located at key protein-coding genes, function in brown adipogenesis, white adipose browning (ie, beige adipogenesis), and brown thermogenesis. In this review, we describe lncRNA properties and highlight functional lncRNAs in these biological processes, with the goal of establishing links between lncRNAs and BAT. Based on the advances of lncRNAs in the regulation of BAT, we discussed the advantages of potential lncRNA-based obesity drugs. Further BAT lncRNA-based drug development may provide new exciting approaches to defend obesity by regulation of fat homeostasis.Keywords: obesity, BAT, thermogenesis, lncRNAs

Myeloblastosis (MYB) is involved in OTSCC. This study tried to probe roles of MYB in OSCC with potential axis.Methods: Expression of MYB and miR-130a in OTSCC was detected. Western blot analysis was utilized to determine epithelial–mesenchymal transition-related protein levels. Dual-luciferase reporter gene assay certified the target relation between miR-130a and CYLD. Moreover, xenograft tumors in nude mice were applied to confirm the in vitro experiments.Results: Both MYB and miR-130a were highly expressed in OTSCC, which promoted cell growth. Meanwhile, silenced miR-130a discouraged cell development enhanced by overexpressed MYB. CYLD was poorly expressed in OTSCC and targeted by miR-130a. Additionally, MYB knockdown activated CYLD to suppress OTSCC by downregulating miR-130a.Conclusion: Our experiment supported that silenced MYB suppressed OTSCC malignancy by inhibiting miR-130a and activating CYLD. This investigation may provide novel insights for OTSCC treatment.Keywords: oral tongue squamous cell carcinoma, MYB, microRNA-130a, CYLD, epithelial–mesenchymal transition, proliferation

Although the researches on the molecular mechanisms of EC have been widely carried out and incremental progress has been made, its overall survival rate is still low. There is cumulative evidence showing that the esophageal microenvironment plays a vital role in the development of EC. In precancerous lesions of the esophagus, high-risk environmental factors can promote the development of precancerous lesions by inducing the production of inflammatory factors and the recruitment of immune cells. In the tumor microenvironment, tumor-promoting cells can inhibit anti-tumor immunity and promote tumor progression through a variety of pathways, such as bone marrow-derived suppressor cells (MDSCs), tumor-associated fibroblasts (CAFs), and regulatory T cells (Tregs). The formation of extracellular hypoxia and acidic microenvironment and the change of extracellular matrix stiffness are also important factors affecting tumor progression and metastasis. Simultaneously, primary tumor-derived cytokines and bone marrow-derived immune cells can also promote the formation of pre-metastasis niche of EC lymph nodes, which are beneficial to EC lymph node metastasis. Further research on the specific mechanism of these processes in the occurrence, development, and metastasis of each EC subtype will support us to grasp the overall pre-cancerous prevention, targeted treatment, and metastatic assessment of EC.Keywords: esophageal cancer, tumor precursor microenvironment, tumor microenvironment, premetastatic niche

In this study, we aimed to determine predictors of low adherence in the Chinese IBD populations and also aimed to compare a self-reported scale to a pharmacy refill index in assessing adherence of 5-ASA and azathioprine taken by Chinese IBD patients.Patients and Methods: Adult patients with IBD who had been taking 5-ASA or azathioprine for at least 3 months were recruited from hospital outpatient clinics. The MPR was calculated from previous six-month pharmacy refill data and the self-reported Morisky Medication Adherence Scale (MMAS-8) was issued through QR code questionnaires. Intentional and unintentional adherence scores were calculated according to specific items. Non-adherence was defined as MMAS-8 scores < 6 or MPR < 0.8.Results: The response rate in the IBD patients was as high as 97%. 5-ASA non-adherence rate assessed by MPR was 30% and 37% by MMAS-8, and azathioprine non-adherence rate assessed was 33% by both MPR and MMAS-8. In a linear regression analysis, MPR value was significantly correlated with MMAS-8 score in 5-ASA group (r=0.4, p=0.003), and significantly correlated with unintentional adherence score (r=0.47, p< 0.001). No significant correlation was observed between MPR value and MMAS-8 score in azathioprine group. Multivariate analysis demonstrated that age (OR: 1.08; 95% CI: 1.02– 1.13; P=0.0015) and previous abdominal surgery (OR: 3.18; 95% CI: 2.09– 4.27; P=0.04) were associated with high medication adherence. While patients who had small intestine lesion (OR: 0.09; 95% CI: 0.01– 0.17; P=0.006) were associated with low adherence.Conclusion: Predictors of low adherence were young age, lesions on small intestine, whereas previous abdominal surgery was a protective factor. This study also demonstrated that the MMAS-8 scale was a valid instrument for assessing 5-ASA adherence in IBD patients. Unintentional non-adherence was significantly related to the total non-adherence, which would allow to use the tool to seek ways for adherence improvement.Keywords: inflammatory bowel disease, medication adherence, self-reported Morisky Medication Adherence Scale, Medication possession ratio

SPSS software version 23.0 was used to analyze the data.Results: A total of 353 strains of pathogens were isolated from urine culture. Among these, 278 (79%) strains belonged to the top 10 most frequently isolated pathogens, comprising 209 (75.2%) Gram-negative bacilli and 69 (24.8%) Gram-positive cocci. Escherichia coli was the most frequently isolated pathogen overall and the most frequently isolated Gram-negative bacillus, and Enterococcus faecalis was the most frequently isolated Gram-positive coccus. Drug sensitivity levels were effectively unchanged for less commonly used drugs, whereas drug resistance rates remained high for commonly used drugs such as ampicillin trihydrate, ampicillin/sulbactam, cefazolin, ceftriaxone, aztreonam, levofloxacin and ciprofloxacin.Conclusion: E. coli and E. faecalis remain the most common Gram-negative bacillus and Gram-positive coccus uropathogens, respectively, in patients with urinary calculi. Mid-stream urine pathogen culture and drug sensitivity tests should be used to select appropriate antibacterial drugs before treatment, particularly for perioperative patients with urinary calculi.Keywords: urine pathogen culture, drug sensitivity, urinary calculi, Escherichia coli, Enterococcus faecalis

The α-Synuclein is a major component of Lewy bodies and Lewy neurites, the pathologic hallmark of PD. It is known that α-Synuclein is phosphorylated (p-α-Synuclein) in PD and tau-hyperphosphorylation (p-Tau) is also a pathologic feature of PD. However, the relationship between p-Synuclein and p-Tau in PD is not clear, in particular in the MPTP model of PD. The purpose of this study was to reveal their relationship in the mouse MPTP model.Methods: Firstly, the p-α-Synuclein, α-Synuclein, p-Tau and Tau protein levels were analyzed. Then, GSK3β activation was determined using immunoblot and immunohistochemical staining. Finally, the dopaminergic neurodegeneration was assessed using Tyrosine Hydroxylase (TH) staining and retrograde labeling and microglial marker were labeled. Microglial activation and nigrostriatal pathway degeneration were observed.Results: The results showed that p-α-Synuclein, α-Synuclein, p-Tau and Tau were upregulated in both hippocampus and substantia nigra of the PD mouse model. Furthermore, p-α-Synuclein and p-Tau were localized in the same regions of substantial nigra (SN) and dentate gyrus (DG) of hippocampus (Hippo). The activated form of GSK3β (phosphor GSK3β Y216) was increased in multiple brain areas. The GSK3β inhibitor AZD1080 injected in MPTP mice suppressed the expression of p-Tau and p-GSK3β and improved motor functions.Conclusion: These findings revealed that p-α-Synuclein and p-Tau proteins are key pathological events leading to neurodegeneration and motor dysfunctions in the mouse MPTP model of PD. Our data suggest that the interference with the GSK3β activity may be an effective approach for the treatment of PD.Keywords: α-Synuclein phosphorylation, Tau phosphorylation, Parkinson’s disease

In this article, we mainly discuss NG-R1 in metabolism and the biological activities, including cardiovascular protection, neuro-protection, anti-diabetes, liver protection, gastrointestinal protection, lung protection, bone metabolism regulation, renal protection, and anti-cancer. The metabolites produced by deglycosylation of NG-R1 exhibit higher permeability and bioavailability. It has been extensively verified that NG-R1 may ameliorate ischemia-reperfusion (IR)-induced injury in cardiovascular and neuronal systems mainly by upregulating the activity of estrogen receptor α-dependent phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) and nuclear factor erythroid-2-related factor 2 (NRF2) pathways and downregulating nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) pathways. However, no specific targets for NG-R1 have been identified. Expectedly, NG-R1 has been used as a main bioactive compound in many Traditional Chinese Medicines clinically, such as Xuesaitong, Naodesheng, XueShuanTong, ShenMai, and QSYQ. These suggest that NG-R1 exhibits a significant potency in drug development.Keywords: notoginsenoside (NG)-R1, Panax notoginseng, micro-circulatory hemostasis, permeability, bioavailability

In the current study, nomogram predict models based on pre-treatment hematological parameters and a modified risk-stratified score system have been built.Methods: A total of 197 patients with oropharyngeal, hypopharyngeal and laryngeal cancers receiving multimodality treatment between 2012 and 2014 were included. The pre-treatment ALB, neutrophil, lymphocyte and platelet count (PLT) were detected. Cancer-specific survival and locoregional recurrence (LRC) by 5 years’ follow-up in the cases were obtained. To integrate clinical characteristics, we propose a modified risk-stratified score system. Kaplan–Meier method, proportional hazards COX model, logistic models were used to establish nomograms within external validation.Results: Five-year LRC was decreased (p=0.004) for 140 patients with pre-treatment NLR < 2.77. Five-year LRC and 5-year cancer-specific survival were decreased (p=0.031, p=0.021) with pre-treatment PLT ≥ 248× 109/L. Comparison of univariate parametric models demonstrated that pre-treatment NLR evaluation and PLT> 248× 109/L were better among tested models. On Bayesian information criteria (BIC) analysis, the optimal prognostic model was then used to develop nomograms predicting 3- and 5-year LRC. The external validation of this predictive model was confirmed in 57 patients from another hospital.Conclusion: Pre-treatment NLR elevation and PLT> 248× 109/L are promising predictors of prognosis in patients with operable HNSCC. Nomograms based on the pre-treatment hematological markers and modified risk-stratified score system provide distinct risk stratifications. There results provided the feasibility of anti-inflammatory and antiplatelet treatments for HNSCC patients.Keywords: head and neck squamous cell carcinoma, neutrophil-lymphocyte ratio, platelet count, albumin, nomogram

We explored the significance of BDR, defined by post-bronchodilator change in FEV1 (BDRFEV1) as a measure reflecting the change in flow and in FVC (BDRFVC) reflecting the change in volume.Methods: We analyzed 2974 participants from a multicenter observational study designed to identify varying COPD phenotypes (SPIROMICS). We evaluated the association of BDR with baseline clinical characteristics, rate of prospective exacerbations and mortality using negative binomial regression and Cox proportional hazards models.Results: A majority of COPD participants exhibited BDR (52.7%). BDRFEV1 occurred more often in earlier stages of COPD, while BDRFVC occurred more frequently in more advanced disease. When defined by increases in either FEV1 or FVC, BDR was associated with a self-reported history of asthma, but not with blood eosinophil counts. BDRFVC was more prevalent in subjects with greater emphysema and small airway disease on CT. In a univariate analysis, BDRFVC was associated with increased exacerbations and mortality, although no significance was found in a model adjusted for post-bronchodilator FEV1.Conclusion: With advanced airflow obstruction in COPD, BDRFVC is more prevalent in comparison to BDRFEV1 and correlates with the extent of emphysema and degree of small airway disease. Since these associations appear to be related to the impairment of FEV1, BDRFVC itself does not define a distinct phenotype nor can it be more predictive of outcomes, but it can offer additional insights into the pathophysiologic mechanism in advanced COPD.Clinical trials registration: ClinicalTrials.gov: NCT01969344T4.Keywords: bronchodilator responsiveness, inspiratory capacity, FVC, FEV1, SPIROMICS

However, the expression, role, and mechanism of ATG3 itself in cancers are rarely revealed. Thus, we explored the expression, function, and mechanism of ATG3 in colon cancer.Materials and methods: The expression of ATG3 was detected in colon cancer tissues and cell lines, as well as in adjacent tumor tissues and normal colon epithelial cells. The effects of ATG3 alteration on proliferation and invasion were further analyzed. The expression and role of miR-431-5p, a potential negative regulator of ATG3, were also studied. Eventually, the role of autophagy in ATG3 related effects in colon cancer was checked.Results: ATG3 is upregulated in colon cancer tissues and cells demonstrated by qPCR and IHC. ATG3 knockdown significantly suppressed proliferation and invasion of colon cancer cells indicated by plate clone formation and Transwell invasion assays. The expression of miR-431-5p is downregulated and negatively correlates with ATG3 in colon cancer. Furthermore, luciferase report system, plate clone formation and Transwell invasion assays demonstrated that miR-431-5p could prohibit cell proliferation and invasion via directly targeting ATG3 in colon cancer. Eventually, Western blot, plate clone formation and Transwell invasion assays proved that autophagy block could antagonize the promotive functions of ATG3 on proliferation and invasion in cancer suggesting autophagy activation accounts for the promotive role of ATG3 on proliferation and invasion in colon cancer.Conclusion: Collectively, ATG3 upregulation, caused by downregulated miR-435-5p, promotes proliferation and invasion via an autophagy-dependent manner in colon cancer suggesting that miR-431-5p/ATG3/autophagy may be a potential therapeutic target in colon cancer.Keywords: colon cancer, proliferation, invasion, ATG3, miR-431-5p, autophagy

Glutaminolysis, a glutamine-fueled intracellular metabolic pathway, is an essential pathway of ferroptosis in cancer cells. Recent findings showed low-concentration paclitaxel (PTX) could inhibit cell death by upregulating p53 expression; downregulating glutaminolysis-related genes.Methods: The therapeutic effect of RSL3 plus low-concentration PTX combination therapy was investigated in HPSCC cells harboring mutant p53 (mtp53). Relative cell viability, ferroptosis-specific lipid peroxidation and relevant protein expression were evaluated.Results: We demonstrated that neither PTX nor RSL3 in low concentration caused significant cell death; however, the combination therapy is shown to induce ferroptosis and significant cell death in mtp53 HPSCC. We discovered that low-concentration PTX enhanced the RSL3-induced ferroptosis by upregulating mtp53 expression. Furthermore, mtp53-mediated transcriptional regulation of SLC7A11 could be the key determinant.Discussion: Although gain-of-function of p53 variants remains to be characterized, our findings provide new insight into the synergistical cell death by regulating ferroptosis and p53.Keywords: HPSCC, ferroptosis, low-concentration paclitaxel, RSL3, synthetic cell death, mtp53, SLC7A11, GOF p53 variants

The aims of this study are to investigate: 1) whether significant differences of thyroid profiles exist between manic and depressive episodes in patients with bipolar disorder (BD); 2) the impact of quetiapine monotherapy on thyroid functions in depressed BD patients.Methods: In this retrospective naturalistic study, we reviewed patients’ information based on an electronic medical system from January 2015 to April 2019. Patients with a discharge diagnosis of BD, a current depressive or manic episode, were screened. All depressed BD patients were treated with quetiapine monotherapy for at least one month. For all patients enrolled, the demographic, clinical data and thyroid functions were recorded. The differences between thyroid profiles including total thyroxine (TT4), total triiodothyronine (TT3), free triiodothyronine (FT3), free thyroxine (FT4) and thyroid-stimulating hormone (TSH) between patients with different episodes were analyzed. In addition, the change of thyroid functions before and after one-month or three-month quetiapine treatment in depressed BD patients was also analyzed.Results: Totally, 28 patients with a manic episode and 58 patients with a depressive episode were enrolled. No significant differences in thyroid profiles were found in patients with different mood episodes. After one-month quetiapine treatment, serum levels of TT4, FT4 and FT3 were significantly reduced (P

The chimeric protein, HBc-N144-NspA, was expressed from a prokaryotic vector and generated HBc-like particles, as determined by transmission electron microscopy. Further, the chimeric protein and control proteins were used to immunize mice and the resulting immune responses evaluated by flow cytometry, enzyme-linked immunosorbent assay, and analysis of serum bactericidal activity (SBA) titer.Results: Evaluation of the immunogenicity of the recombinant HBc-N144-NspA protein showed that it elicited the production of high levels of NspA-specific total IgG. The SBA titer of HBc-N144-NspA/F reached 1:16 2 weeks after the last immunization in BALB/c mice, when human serum complement was included in the vaccine. Immunization of HBc-N144-NspA, even without adjuvant, induced high levels of IL-4 and a high IgG1 to IgG2a ratio, confirming induction of an intense Th2 immune response. Levels of IL-17A increased rapidly in mice after the first immunization with HBc-N144-NspA, indicating the potential for this vaccine to induce a mucosal immune response. Meanwhile, the immunization of HBc-N144-NspA without adjuvant induced only mild inflammatory infiltration into the mouse muscle tissue.Conclusion: This study demonstrates that modification using HBc renders NspA a candidate vaccine, which can trigger protective immunity against NMB.Keywords: hepatitis B core protein, Neisserial surface protein A, virus-like particles, recombinant protein vaccine, Neisseria meningitidis serogroup B

This paper aims to provide a comprehensive review of the sex-related influence of OT and VP on social cognition, focusing on partner preference and sexual orientation, trust and relevant behaviors, memory modulation, and emotion regulation. Most studies have suggested that OT facilitates familiar-partner preference in both sexes, with females being more significant, increased trust in others, especially for male, enhanced memory in either sex, and reduced anxious emotion in males. However, VP-regulated social cognition has been less studied. Other relevant studies have indicated that VP facilitated familiar-partner preference, improved memory, induced empathy formation, increased positive-emotion recognition, and induced anxiety without any sex difference. However, there was a male preponderance among studies, and results were often too complex to draw firm conclusions. Clarifying the interplay between OT/VP and sex hormones in the regulation of social cognition is necessary for further applications.Keywords: oxytocin, vasopressin, sexual difference, social cognition, social behavior

In this article, we assessed the efficacy and safety of olaparib maintenance therapy on platinum-sensitive ovarian cancer patients with BRCA mutations through a meta-analysis of available randomized controlled trials (RCTs) to provide more evidence for its clinical applications.Methods: We searched PubMed, Embase, Wanfang, CNKI, Web of Science, Cochrane Library, and VIP databases from 1 August 2018 to identify RCTs and finally included four RCTs (seven articles) with 567 eligible participants beyond the participants, interventions, comparisons, outcomes, and study design regulation. The outcomes of olaparib efficacy including progression-free survival (PFS) and overall survival (OS) were measured by HR and 95% CI, while the quality of life was evaluated by calculating the combination of P-value. Seven common adverse events were tested by risk ratio and 95% CI as the outcomes of olaparib safety. These data were analyzed, and the forest figures were produced using Review Manager 5.3.Results: Compared with other interventions (ie, placebo or chemotherapy drugs), olaparib significantly prolonged PFS (HR=0.31, 95% CI=0.15–0.62) and slightly improved OS (HR=0.75, 95% CI=0.56–0.99), but did not influence the quality of life (P=0.058) in the patients with platinum-sensitive BRCA-mutated ovarian cancer. Additionally, the toxicity profile of olaparib involved anemia, fatigue, vomiting, diarrhea, and nausea with grade 1–2.Conclusion: This meta-analysis suggests that olaparib maintenance therapy is effective and well-tolerated for the patients with platinum-sensitive BRCA-mutated ovarian cancer. More updated RCTs and long-term follow-up should be conducted to compare and analyze the efficacy and toxicity of olaparib at different doses in ovarian cancer patients.Keywords: olaparib, ovarian cancer, efficacy, adverse event, meta-analysis

Abstract: Xiaohua Jiang,* Jing Ye,* Zhihuai Dong, Sunhong Hu, Mang Xiao Department of Otolaryngology Head and Neck Surgery, Sir Run Shaw Hospital, College of Medicine, Zhejiang University, Hangzhou, Zhejiang, China *These authors contributed equally to this work Abstract: Head and neck squamous cell carcinoma (HNSCC) is highly variable by tumor site, histologic type, molecular characteristics, and clinical outcome. During recent years, emerging targeted therapies have been focused on driver genes. HNSCC involves several genetic alterations, such as co-occurrence, multiple feedback loops, and cross-talk communications. These different kinds of genetic alterations interact with each other and mediate targeted therapy response. In the current review, it is emphasized that future treatment strategy in HNSCC will not solely be based on “synthetic lethality” approaches directed against overactivated genes. More importantly, biologic, genetic, and epigenetic alterations of HNSCC will be taken into consideration to guide the therapy. The emerging genetic alterations in HNSCC and its effect on targeted therapy response are discussed in detail. Hopefully, novel combination regimens for the treatment of HNSCC can be developed.

Abstract: Analyzing $e^+e^-$ collision data corresponding to an integrated luminosity of $7.33~\mathrm{fb}^{-1}$ collected at center-of-mass energies between 4.128 and 4.226~GeV with the BESIII detector, we measure the branching fraction of the semileptonic decay $D^+_{s}\to K^0 e^+\nu_e$ to be $(2.98\pm0.23\pm0.12)\times10^{-3}$. The $D_s^+\to K^0$ hadronic form factor is determined from the differential decay rate of $D^+_s\to K^0 e^+\nu_e$ to be $f^{K^0}_+(0)=0.636\pm0.049\pm0.013$. For both measurements, the first uncertainty is statistical and the second systematic. The branching fraction and form factor measurements are factors of 1.6 and 1.7 more precise than the previous world averages, respectively., Comment: 13 pages, 6 figures

Abstract: Using $e^+e^-$ collision data collected with the BESIII detector at the BEPCII collider at center-of-mass energies between 3.510 and 4.914GeV, corresponding to an integrated luminosity of 25 fb$^{-1}$, we measure the Born cross sections for the process $e^+e^-\to K^-\bar{\Xi}^+\Lambda/\Sigma^{0}$ at thirty-five energy points with a partial-reconstruction strategy. By fitting the dressed cross sections of $e^+e^-\to K^-\bar{\Xi}^+\Lambda/\Sigma^{0}$, evidence for $\psi(4160) \to K^{-}\bar\Xi^{+}\Lambda$ is found for the first time with a significance of 4.4$\sigma$, including systematic uncertainties. No evidence for other possible resonances is found. In addition, the products of electronic partial width and branching fraction for all assumed resonances decaying into $K^{-}\bar\Xi^{+}\Lambda/\Sigma^{0}$ are determined., Comment: 26 pages,5 tables, 4 figures, consistent with the publication in JHEP07(2024)258

Abstract: Using $e^+e^-$ annihilation data sets corresponding to an integrated luminosity of 4.5 $\text{fb}^{-1}$, collected with the BESIII detector at center-of-mass energies between 4.600 and 4.699 GeV, we report the first measurements of the absolute branching fractions $\mathcal{B}(\Lambda_c^+\to pK_{L}^{0})=(1.67 \pm 0.06 \pm 0. 04)\%$, $\mathcal{B}(\Lambda_c^+\to pK_{L}^{0}\pi^+\pi^-)=(1.69 \pm 0.10 \pm 0.05)\%$, and $\mathcal{B}(\Lambda_c^+\to pK_{L}^{0}\pi^0)=(2.02 \pm 0.13 \pm 0.05)\%$, where the first uncertainties are statistical and the second systematic. Combining with the known branching fractions of $\Lambda_c^+ \to pK_{S}^{0}$, $\Lambda_c^+ \to pK_{S}^{0}\pi^+\pi^-$, and $\Lambda_c^+ \to pK_{S}^{0}\pi^0$, we present the first measurements of the $K_{S}^{0}$-$K_{L}^{0}$ asymmetries $R(\Lambda_c^+, K_{S,L}^0X) = \frac{\mathcal{B}(\Lambda_c^+ \to K_{S}^{0} X) - \mathcal{B}(\Lambda_c^+ \to K_{L}^{0} X)}{\mathcal{B}(\Lambda_c^+ \to K_{S}^{0} X) + \mathcal{B}(\Lambda_c^+ \to K_{L}^{0} X)}$ in charmed baryon decays: $R(\Lambda_c^+, pK_{S,L}^0) = -0.025 \pm 0.031$, $R(\Lambda_c^+, pK_{S,L}^0\pi^+\pi^-) = -0.027 \pm 0.048$, and $R(\Lambda_c^+, pK_{S,L}^0\pi^0) =-0.015 \pm 0.046$. No significant asymmetries within the uncertainties are observed., Comment: 19 pages, 2 figures, revised with JHEP comments

Abstract: We perform the first amplitude analysis of $D^+_s \to \pi^+\pi^+\pi^-\pi^0$ decays, based on data samples of electron-positron collisions recorded with the BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV, corresponding to an integrated luminosity of 7.33~fb$^{-1}$. We report the observation of $D_{s}^{+} \to f_0(980)\rho(770)^{+}$ with a statistical significance greater than 10$\sigma$ and determine the branching fractions $\mathcal{B}(D_s^+\to\pi^+\pi^+\pi^-\pi^0|_{{\rm non}-\eta})=(2.04\pm0.08_{\rm stat.}\pm0.05_{\rm syst.})\%$ and $\mathcal{B}(D_s^+\to\eta\pi^+)=(1.56\pm0.09_{\rm stat.}\pm0.04_{\rm syst.})\%$. Moreover, we measure the relative branching fraction between $\phi\to\pi^+\pi^-\pi^0$ and $\phi\to K^+K^-$ to be $\frac{\mathcal{B}(\phi(1020) \to \pi^+\pi^-\pi^0)}{\mathcal{B}(\phi(1020) \to K^+K^-)}=0.230 \pm 0.014_{\rm stat.} \pm 0.010_{\rm syst.}$, which deviates from the world average value by more than $4\sigma$.

Abstract: Based on 368.5 pb$^{-1}$ of $e^+e^-$ collision data collected at center-of-mass energies 4.914 and 4.946 GeV by the BESIII detector, the $e^+e^- \to \phi\chi_{c1}(3872)$ process is searched for the first time. No significant signal is observed and the upper limits at the 90\% confidence level on the product of the Born cross section $\sigma(e^+e^- \to \phi\chi_{c1}(3872))$ and the branching fraction $\mathcal{B}[\chi_{c1}(3872)\to\pi^+\pi^- J/\psi]$ at 4.914 and 4.946 GeV are set to be 0.85 and 0.96 pb, respectively. These measurements provide useful information for the production of the $\chi_{c1}(3872)$ at $e^+e^-$ collider and deepen our understanding about the nature of this particle., Comment: 11 pages, 3 figures

Abstract: Using a sample of $(10087\pm 44)\times10^{6}$ $J/\psi$ events collected by the BESIII detector at the BEPCII collider, we search for the decay $X(1870)\to K^+ K^-\eta$ via the $J/\psi\to \omega K^+ K^- \eta$ process for the first time. No significant $X(1870)$ signal is observed. The upper limit on the branching fraction of the decay $ J/\psi\to \omega X(1870) \to\omega K^+ K^- \eta$ is determined to be $9.55\times 10^{-7}$ at the $90\%$ confidence level. In addition, the branching faction $B(J/\psi\to\omega K^+ K^- \eta)$ is measured to be $(3.33\pm0.02(\rm{stat.})\pm 0.12(\rm{syst.}))\times 10^{-4}$.

Abstract: In this work we try to search for signals generated by ultra-heavy dark matter at the Large High Altitude Air Shower Observatory (LHAASO) data. We look for possible gamma-ray by dark matter annihilation or decay from 16 dwarf spheroidal galaxies in the field of view of LHAASO. Dwarf spheroidal galaxies are among the most promising targets for indirect detection of dark matter which have low fluxes of astrophysical $\gamma$-ray background while large amount of dark matter. By analyzing more than 700 days observational data at LHAASO, no significant dark matter signal from 1 TeV to 1 EeV is detected. Accordingly we derive the most stringent constraints on the ultra-heavy dark matter annihilation cross-section up to EeV. The constraints on the lifetime of dark matter in decay mode are also derived., Comment: 17 pages, 12 figures, accepted by PRL

Abstract: Based on $2.7 \times 10^9~\psi(3686)$ decays collected with the BESIII detector, the radiative decay $\psi(3686)\to\gamma2(\pi^{+}\pi^{-})\eta$ is investigated to measure properties of S- and P-wave charmonium states. The branching fraction of the decay $\eta_{c}(1S) \to 2(\pi^{+}\pi^{-})\eta$, which is found to have a strong dependence on the interference pattern between $\eta_c(1S)$ and non-$\eta_c(1S)$ processes, is measured in both destructive and constructive interference scenarios for the first time. The mass and width of the $\eta_{c}(1S)$ are measured to be $M=(2984.14 \pm 0.13 \pm 0.38)$ MeV/$c^{2}$ and $\Gamma=(28.82 \pm 0.11 \pm 0.82)$ MeV, respectively. Clear signals for the decays of the $\chi_{cJ}(J=0,1,2)$ and the $\eta_{c}(2S)$ to $2(\pi^{+}\pi^{-})\eta$ are also observed for the first time, and the corresponding branching fractions are measured. The ratio of the branching fractions between the $\eta_{c}(2S)$ and $\eta_{c}(1S)$ decays is significantly lower than the theoretical prediction, which might suggest different dynamics in their decays.

Abstract: The $J/\psi, \psi(3686) \to \Sigma^0 \bar{\Sigma}^{0}$ processes and subsequent decays are studied using the world's largest $J/\psi$ and $\psi(3686)$ data samples collected with the BESIII detector. The strong-$CP$ symmetry is tested in the decays of the $\Sigma^0$ hyperons for the first time by measuring the decay parameters, $\alpha_{\Sigma^0} = -0.0017 \pm 0.0021 \pm 0.0018$ and $\bar{\alpha}_{\Sigma^0} = 0.0021 \pm 0.0020 \pm 0.0022$. The weak-$CP$ test is performed in the subsequent decays of their daughter particles $\Lambda$ and $\bar{\Lambda}$. Also for the first time, the transverse polarizations of the $\Sigma^0$ hyperons in $J/\psi$ and $\psi(3686)$ decays are observed with opposite directions, and the ratios between the S-wave and D-wave contributions of the $J/\psi, \psi(3686) \to \Sigma^0 \bar{\Sigma}^{0}$ decays are obtained. These results are crucial to understand the decay dynamics of the charmonium states and the production mechanism of the $\Sigma^0-\bar{\Sigma}^0$ pairs.

Abstract: We present a measurement of the integrated luminosity of $e^+e^-$ collision data collected with the BESIII detector at the BEPCII collider at a center-of-mass energy of $E_{\rm cm} = 3.773$~GeV. The integrated luminosities of the data sets taken from December 2021 to June 2022, from November 2022 to June 2023, and from October 2023 to February 2024 are determined to be $4.995 \pm 0.019$~fb$^{-1}$, $8.157 \pm 0.031$~fb$^{-1}$, and $4.191 \pm 0.016$~fb$^{-1}$, respectively, by analyzing large angle Bhabha scattering events. The uncertainties are dominated by systematic effects and the statistical uncertainties are negligible. Our results provide essential input for future analyses and precision measurements.

Abstract: Based on $(2712.4\pm 14.3)\times10^{6}$ $\psi(3686)$ events, we investigate four hadronic decay modes of the $P$-wave charmonium spin-singlet state $h_c(^1P_1) \to h^+ h^- \pi^0/\eta$ ($h=\pi$ or $K$) via the process $\psi(3686) \to \pi^{0}h_c$ at BESIII. The $h_c \to \pi^+ \pi^- \pi^0$ decay is observed with a significance of 9.6$\sigma$ after taking into account systematic uncertainties. Evidences for $h_c \to K^+ K^- \pi^0$ and $h_c \to K^+ K^- \eta$ are found with significances of $3.5\sigma$ and $3.3\sigma$, respectively, after considering the systematic uncertainties. The branching fractions of these decays are measured to be $\mathcal{B}(h_c \to \pi^+ \pi^- \pi^0)=(1.36\pm0.16\pm0.14)\times10^{-3}$, $\mathcal{B}(h_c \to K^+ K^- \pi^0)=(3.26\pm0.84\pm0.36)\times10^{-4}$, and $\mathcal{B}(h_c \to K^+ K^- \eta)=(3.13\pm1.08\pm0.38)\times10^{-4}$, where the first uncertainties are statistical and the second are systematic. No significant signal of $h_c\to\pi^+\pi^-\eta$ is found, and the upper limit of its decay branching fraction is determined to be $\mathcal{B}(h_c\to\pi^+\pi^-\eta) < 4.0 \times 10^{-4}$ at 90% confidence level., Comment: 9 pages, 7 figures

Abstract: We measure the absolute branching fractions of semileptonic $D^+_s$ decays via the $e^+e^-\to D_s^{*+}D_s^{*-}$ process using $e^+e^-$ collision data corresponding to an integrated luminosity of $10.64~\mathrm{fb}^{-1}$ collected by the BESIII detector at center-of-mass energies between 4.237 and 4.699 GeV. The branching fractions are ${\mathcal B}(D_s^+\to \eta e^+\nu_e)=(2.35\pm0.11_{\rm stat}\pm 0.10_{\rm syst})\%,$ ${\mathcal B}(D_s^+\to \eta^\prime e^+\nu_e)=(0.82\pm0.09_{\rm stat}\pm 0.04_{\rm syst})\%,$ ${\mathcal B}(D_s^+\to \phi e^+\nu_e)=(2.21\pm0.16_{\rm stat}\pm 0.11_{\rm syst})\%,$ ${\mathcal B}(D_s^+\to f_0(980) e^+\nu_e,f_0(980)\to\pi^+\pi^-)=(0.15\pm0.02_{\rm stat}\pm 0.01_{\rm syst})\%,$ ${\mathcal B}(D_s^+\to K^0 e^+\nu_e)=(0.24\pm0.04_{\rm stat}\pm 0.01_{\rm syst})\%,$ and ${\mathcal B}(D_s^+\to K^{*0} e^+\nu_e)=(0.19\pm0.03_{\rm stat}\pm 0.01_{\rm syst})\%.$ These results are consistent with those measured via the $e^+e^-\to D_s^{*\pm}D_s^{\mp}$ process by BESIII and CLEO. The hadronic transition form factors $D^+_s\to \eta e^+\nu_e$, $D^+_s\to \eta^\prime e^+\nu_e$, and $D^+_s\to K^0 e^+\nu_e$ at four-momentum transfer squared $q^2$ = 0 are determined to be $f^{\eta}_+(0) = 0.482 \pm 0.011_{\rm stat} \pm 0.009_{\rm syst}\pm0.004_{\rm input},$ $f^{\eta^{\prime}}_+(0) = 0.562 \pm 0.031_{\rm stat} \pm 0.014_{\rm syst}\pm0.003_{\rm input},$ and $f^{K^0}_+(0) = 0.624 \pm 0.052_{\rm stat} \pm 0.013_{\rm syst}\pm0.002_{\rm input}.$, Comment: 14 pages, 3 figures

Abstract: Edge-AI computing requires high energy efficiency, low power consumption, and relatively high flexibility and compact area, challenging the AI-chip design. This work presents a 0.96 pJ/SOP heterogeneous neuromorphic system-on-chip (SoC) with fullerene-like interconnection topology for edge-AI computing. The neuromorphic core integrates different technologies to augment computing energy efficiency, including sparse computing, partial membrane potential updates, and non-uniform weight quantization. Multiple neuromorphic cores and multi-mode routers form a fullerene-like network-on-chip (NoC). The average degree of communication nodes exceeds traditional topologies by 32%, with a minimal degree variance of 0.93, allowing advanced decentralized on-chip communication. Additionally, the NoC can be scaled up through extended off-chip high-level router nodes. A RISC-V CPU and a neuromorphic processor are tightly coupled and fabricated within a 5.42 mm^2 die area under 55 nm CMOS technology. The chip has a low power density of 0.52 mW/mm^2, reducing 67.5% compared to related works, and achieves a high neuron density of 30.23 K/mm^2. Eventually, the chip is demonstrated to be effective on different datasets and achieves 0.96 pJ/SOP energy efficiency., Comment: 5 pages, 8 figures

Abstract: Using data samples with an integrated luminosity of $4.67~\mathrm{fb}^{-1}$ collected by the BESIII detector operating at the BEPCII collider, we search for the process $e^+e^- \rightarrow \eta' \psi(2S)$ at center-of-mass energies from $4.66$ to $4.95~\mathrm{GeV}$. No significant signal is observed, and upper limits for the Born cross sections $\sigma^B(e^+e^-\rightarrow\eta'\psi(2S))$ at the 90\% confidence level are determined.

Abstract: Based on $(2712.4 \pm 14.3) \times 10^{6}$ $ e^{+}e^{-}\to\psi(3686)$ events collected with the BESIII detector operating at the BEPCII collider, we report the first evidence of $\chi_{c0}\to \Lambda\bar \Lambda \phi$ decays and the first observation of $\chi_{c1,2}\to \Lambda\bar \Lambda \phi$ decays, with significances of $4.5\sigma$, $11.3\sigma$ and $13.0\sigma$, respectively. The decay branching fractions of $\chi_{c0,1,2}\to \Lambda\bar \Lambda\phi$ are measured to be $( 2.99\pm1.24\pm0.19) \times 10^{-5}$, $(6.01\pm0.90\pm0.40 )\times 10^{-5}$, and $(7.13\pm0.81\pm0.36) \times 10^{-5}$, where the first uncertainties are statistical and the second systematic. No obvious enhancement near the $\Lambda \bar{\Lambda}$ production threshold or excited $\Lambda$ state is found in the $\Lambda \phi$ (or $\bar{\Lambda}\phi$) system., Comment: 10 pages, 9 figures

Abstract: Using $(27.12\pm 0.14)\times10^{8}$ $\psi(3686)$ events collected with the BESIII detector, we present the first observation of the decays $\chi_{cJ}\to\Lambda\bar{\Lambda}\omega$, where $J=0, 1, 2$, with statistical significances of $11.7 \sigma, 11.2 \sigma$, and $11.8 \sigma$. The branching fractions of these decays are determined to be $\mathcal{B}(\chi_{c0}\to\Lambda\bar{\Lambda}\omega)=({2.37 \pm 0.22 \pm 0.23}) \times 10^{-4}$, $\mathcal{B}(\chi_{c1}\to\Lambda\bar{\Lambda}\omega)=({1.01 \pm 0.10 \pm 0.11}) \times 10^{-4}$, and $\mathcal{B}(\chi_{c2}\to\Lambda\bar{\Lambda}\omega)=({1.40 \pm 0.13 \pm 0.17}) \times 10^{-4}$, where the first uncertainties are statistical and the second are systematic. We observe no clear intermediate structures., Comment: 11 pages, 10 figures

Abstract: The KM2A is the largest sub-array of the Large High Altitude Air Shower Observatory (LHAASO). It consists of 5216 electromagnetic particle detectors (EDs) and 1188 muon detectors (MDs). The data recorded by the EDs and MDs are used to reconstruct primary information of cosmic ray and gamma-ray showers. This information is used for physical analysis in gamma-ray astronomy and cosmic ray physics. To ensure the reliability of the LHAASO-KM2A data, a three-level quality control system has been established. It is used to monitor the status of detector units, stability of reconstructed parameters and the performance of the array based on observations of the Crab Nebula and Moon shadow. This paper will introduce the control system and its application on the LHAASO-KM2A data collected from August 2021 to July 2023. During this period, the pointing and angular resolution of the array were stable. From the observations of the Moon shadow and Crab Nebula, the results achieved using the two methods are consistent with each other. According to the observation of the Crab Nebula at energies from 25 TeV to 100 TeV, the time averaged pointing errors are estimated to be $-0.003^{\circ} \pm 0.005^{\circ}$ and $0.001^{\circ} \pm 0.006^{\circ}$ in the R.A. and Dec directions, respectively., Comment: 15 pages, 9 figures

Abstract: The processes $h_c\to\gamma P(P = \eta^\prime,~\eta,~\pi^0)$ are studied with a sample of $(27.12\pm0.14)\times10^{8}$ $\psi(3686)$ events collected by the BESIII detector at the BEPCII collider. The decay $h_{c}\rightarrow\gamma\eta$ is observed for the first time with the significance of $9.0\,\sigma$, and the branching fraction is determined to be $(3.77\pm0.55\pm0.13\pm0.26)\times10^{-4}$, while $\mathscr{B}(h_{c}\rightarrow\gamma\eta^\prime)$ is measured to be $(1.40\pm0.11\pm0.04\pm0.10)\times10^{-3}$, where the first uncertainties are statistical, the second systematic, and the third from the branching fraction of $\psi(3686)\rightarrow\pi^{0}h_c$. The combination of these results allows for a precise determination of $R_{h_c}=\frac{\mathscr{B}(h_c\rightarrow\gamma\eta)}{\mathscr{B}(h_c\rightarrow\gamma\eta^\prime)}$, which is calculated to be $(27.0\pm4.4\pm1.0)\%$. The results are valuable for gaining a deeper understanding of $\eta-\eta^\prime$ mixing, and its manifestation within quantum chromodynamics. No significant signal is found for the decay $h_c\rightarrow\gamma\pi^{0}$, and an upper limit is placed on its branching fraction of $\mathscr{B}(h_c\rightarrow\gamma\pi^{0})<5.0\times10^{-5}$, at the 90$\%$ confidence level.

Abstract: Accurate knowledge of the properties of hydrogen at high compression is crucial for astrophysics (e.g. planetary and stellar interiors, brown dwarfs, atmosphere of compact stars) and laboratory experiments, including inertial confinement fusion. There exists experimental data for the equation of state, conductivity, and Thomson scattering spectra. However, the analysis of the measurements at extreme pressures and temperatures typically involves additional model assumptions, which makes it difficult to assess the accuracy of the experimental data. rigorously. On the other hand, theory and modeling have produced extensive collections of data. They originate from a very large variety of models and simulations including path integral Monte Carlo (PIMC) simulations, density functional theory (DFT), chemical models, machine-learned models, and combinations thereof. At the same time, each of these methods has fundamental limitations (fermion sign problem in PIMC, approximate exchange-correlation functionals of DFT, inconsistent interaction energy contributions in chemical models, etc.), so for some parameter ranges accurate predictions are difficult. Recently, a number of breakthroughs in first principle PIMC and DFT simulations were achieved which are discussed in this review. Here we use these results to benchmark different simulation methods. We present an update of the hydrogen phase diagram at high pressures, the expected phase transitions, and thermodynamic properties including the equation of state and momentum distribution. Furthermore, we discuss available dynamic results for warm dense hydrogen, including the conductivity, dynamic structure factor, plasmon dispersion, imaginary-time structure, and density response functions. We conclude by outlining strategies to combine different simulations to achieve accurate theoretical predictions.

Abstract: Using 9.0 $\rm fb^{-1}$ of $e^+e^-$ collision data collected at center-of-mass energies from 4.178 to 4.278 GeV with the BESIII detector at the BEPCII collider, we perform the first search for the radiative transition $\chi_{c1}(3872)\to\gamma \psi_2(3823)$. No $\chi_{c1}(3872)\to\gamma \psi_2(3823)$ signal is observed. The upper limit on the ratio of branching fractions $\mathcal{B}(\chi_{c1}(3872)\to\gamma \psi_2(3823), \psi_2(3823)\to\gamma\chi_{c1})/\mathcal{B}(\chi_{c1}(3872)\to\pi^+\pi^- J/\psi)$ is set as 0.075 at the 90\% confidence level. Our result contradicts theoretical predictions under the assumption that the $\chi_{c1}(3872)$ is the pure charmonium state $\chi_{c1}(2P)$., Comment: 8 pages, 2 figures

Abstract: The first source catalog of Large High Altitude Air Shower Observatory reported the detection of a very-high-energy gamma ray source, 1LHAASO J1219+2915. In this paper a further detailed study of the spectral and temporal behavior of this point-like source have been carried. The best-fit position of the TeV source ($\rm{RA}=185.05^{\circ}\pm0.04^{\circ}$, $\rm{Dec}=29.25^{\circ}\pm0.03^{\circ}$) is compatible with NGC 4278 within $\sim0.03$ degree. Variation analysis shows an indication of the variability at a few months level in the TeV band, which is consistent with low frequency observations. Based on these observations, we report the detection of TeV $\gamma$-ray emissions from this low-luminosity AGN NGC 4278. The observations by LHAASO-WCDA during active period has a significance level of 8.8\,$\sigma$ with best-fit photon spectral index $\varGamma=2.56\pm0.14$ and a flux $f_{1-10\,\rm{TeV}}=(7.0\pm1.1_{\rm{sta}}\pm0.35_{\rm{syst}})\times10^{-13}\,\rm{photons\,cm^{-2}\,s^{-1}}$, or approximately $5\%$ of the Crab Nebula. The discovery of VHE from NGC 4278 indicates that the compact, weak radio jet can efficiently accelerate particles and emit TeV photons., Comment: 11 pages, 5 figures
