RESUMO
Tissue-resident memory T cells (TRM) are a specialized subset of T cells that reside in tissues and provide long-term protective immunity against pathogens that enter the body through that specific tissue. TRM cells have specific phenotype and reside preferentially in barrier tissues. Recent studies have revealed that TRM cells are the main target of immune checkpoint inhibitor immunotherapy since their role in cancer immunosurveillance. Furthermore, TRM cells also play a crucial part in pathogenesis of immune-related adverse events (irAEs). Here, we provide a concise review of biological characteristics of TRM cells, and the major advances and recent findings regarding their involvement in immune checkpoint inhibitor immunotherapy and the corresponding irAEs.

Biological antibodies targeting key cytokines such as IL-17 and IL-23 have revolutionized psoriasis outcome. However, the recurrence remains an urgent challenge to be addressed. Currently, most of the descriptions of skin T-cell characteristics in psoriasis are derived from lesional and non-lesional skin, and their characteristics in resolved lesions (clinically healed lesions) remain vague. In order to further elucidate the cellular mechanism of recurrence, we performed single-cell sequencing and multiplexed immunohistochemical staining of T-cell subsets in autologous resolved lesion (RL), on-site recurrent psoriatic lesion (PL), and adjacent normal-appearing skin (NS) of psoriasis. By comparing with PL and NS tissues, we identified three potential cellular candidates for recurrence in clinically healed lesions: IL-17A/F double producing T cells, unstable Tregs and quiescent TRMs. Our results provide research clues for elucidating the immunological recurrence mechanism of psoriasis, and further work is needed to deepen our findings.

Interleukin-17 s (IL-17s) are well-known proinflammatory cytokines, and their antagonists perform excellently in the treatment of inflammatory skin diseases such as psoriasis. However, their physiological functions have not been given sufficient attention by clinicians. IL-17s can protect the host from extracellular pathogens, maintain epithelial integrity, regulate cognitive processes and modulate adipocyte activity through distinct mechanisms. Here, we present a systematic review concerning the physiological functions of IL-17s. Our goal is not to negate the therapeutic effect of IL-17 antagonists, but to ensure their safe use and reasonably explain the possible adverse events that may occur in their application.

The matrix product state (MPS) Ansatz offers a promising approach for finding the ground state of molecular Hamiltonians and solving quantum chemistry problems. Building on this concept, the proposed technique of quantum circuit MPS (QCMPS) enables the simulation of chemical systems using a relatively small number of qubits. In this study, we enhance the optimization performance of the QCMPS Ansatz by employing the variational quantum imaginary time evolution (VarQITE) approach. Guided by McLachlan's variational principle, the VarQITE method provides analytical metrics and gradients, resulting in improved convergence efficiency and robustness of the QCMPS. We validate these improvements numerically through simulations of H2, H4, and LiH molecules. In addition, given that VarQITE is applicable to non-Hermitian Hamiltonians, we evaluate its effectiveness in preparing the ground state of transcorrelated Hamiltonians. This approach yields energy estimates comparable to the complete basis set (CBS) limit while using even fewer qubits. In particular, we perform simulations of the beryllium atom and LiH molecule using only three qubits, maintaining high fidelity with the CBS ground state energy of these systems. This qubit reduction is achieved through the combined advantages of both the QCMPS Ansatz and transcorrelation. Our findings demonstrate the potential practicality of this quantum chemistry algorithm on near-term quantum devices.
RESUMO
The advent of Neural-network Quantum States (NQS) has significantly advanced wave function ansatz research, sparking a resurgence in orbital space variational Monte Carlo (VMC) exploration. This work introduces three algorithmic enhancements to reduce computational demands of VMC optimization using NQS: an adaptive learning rate algorithm, constrained optimization, and block optimization. We evaluate the refined algorithm on complex multireference bond stretches of H2O and N2 within the cc-pVDZ basis set and calculate the ground-state energy of the strongly correlated chromium dimer (Cr2) in the Ahlrichs SV basis set. Our results achieve superior accuracy compared to coupled cluster theory at a relatively modest CPU cost. This work demonstrates how to enhance optimization efficiency and robustness using these strategies, opening a new path to optimize large-scale restricted Boltzmann machine-based NQS more effectively and marking a substantial advancement in NQS's practical quantum chemistry applications.
RESUMO
We are interested in estimating the effect of a treatment applied to individuals at multiple sites, where data is stored locally for each site. Due to privacy constraints, individual-level data cannot be shared across sites; the sites may also have heterogeneous populations and treatment assignment mechanisms. Motivated by these considerations, we develop federated methods to draw inferences on the average treatment effects of combined data across sites. Our methods first compute summary statistics locally using propensity scores and then aggregate these statistics across sites to obtain point and variance estimators of average treatment effects. We show that these estimators are consistent and asymptotically normal. To achieve these asymptotic properties, we find that the aggregation schemes need to account for the heterogeneity in treatment assignments and in outcomes across sites. We demonstrate the validity of our federated methods through a comparative study of two large medical claims databases.

Background: Sepsis is an uncontrolled systemic inflammatory response. Long noncoding RNAs (lncRNAs) are involved in the pathogenesis of sepsis. However, little is known about the roles of lncRNAs in sepsis-induced myocardial dysfunction. Objective: We aimed to determine the regulatory mechanism of lncRNAs in sepsis-induced myocardial dysfunction. Methods: In this study, we analysed the lncRNA and mRNA expression profiles using microarray analysis. Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, protein-protein interaction network, and gene set enrichment analysis were used to evaluate the data. We also constructed coding and noncoding coexpression and competing endogenous RNA networks to investigate the mechanisms. Results: In vivo lipopolysaccharide -induced sepsis rat model was established. A total of 387 lncRNAs and 1,952 mRNAs were identified as significantly changed in the left ventricle. Kyoto Encyclopedia of Genes and Genomes analysis of mRNAs showed that the upregulated genes were mainly enriched in the "complement and coagulation cascade pathway" and "immune-related biological processes" terms. Eight significantly changed lncRNAs detected by RT-qPCR may be responsible for these processes. A competing endogenous RNA network was generated, and the results indicated that eight lncRNAs were related to the "calcium ion binding" process. Conclusion: These results demonstrate that crosstalk between lncRNAs and mRNAs may play important roles in the development of sepsis-induced myocardial dysfunction.
RESUMO
In recent years,great progress has been achieved in the application of immune checkpoint inhibitors (ICI) in tumor immunotherapy.However,a variety of adverse reactions induced by ICI have been reported.Despite the high overall incidence of adverse reactions caused by ICI,some adverse reactions,such as immune-related pancreatitis,are rare in clinical practice.In this paper,a case of immune-related pancreatitis after treatment of advanced gastric cancer with nivolumab was identified.We analyzed the cause,treatment,incidence,and risk factors of the adverse reaction,aiming to improve the clinical diagnosis,treatment,and safe medication of rare adverse reactions associated with ICI.

This study aimed to evaluate the variability of dabigatran plasma concentration and the association with clinical events in Chinese patients treated with dabigatran etexilate (DE) for non-valvular atrial fibrillation (NVAF). The steady-state concentration of dabigatran (the active metabolite of DE) was determined at trough and peak. The effect of dabigatran concentration variability and related factors on clinical outcomes were explored. Data from 86 patients receiving a fixed dose of 110 mg showed that dabigatran trough concentration varied remarkably. Age, BMI and history of heart failure were identified as important covariates for dabigatran trough concentration. Dabigatran trough concentration (P = 0.002) and history of hypertension (P = 0.012) scores were identified as key factors for predicting the risk of bleeding events. Dabigatran trough concentration, affected by Age, BMI and history of heart failure, may serve as an independent risk factor for bleeding events in Chinese patients treated with DE for NVAF.

The aim of this study was to elucidate the roles played by circular RNAs (circRNAs) in the mechanism underlying submandibular gland (SMG) dysfunction in hypertension. We employed RNA-seq to analyze the circRNA and mRNA expression profiles of SMGs. Seventy-five differentially expressed (DE) circRNAs and 691 DE mRNAs were determined to be significantly altered in spontaneously hypertensive rats. Altered mRNAs were primarily related to the immune system and immune response. Eight circRNAs were selected for further analysis. Cell adhesion molecules were determined to be the most strongly enriched pathway through analysis of DE mRNAs, the coding noncoding gene co-expression (CNC) network and the competitive endogenous RNA (ceRNA) network. The salivary secretion pathway was observed to be notably enriched through analysis of the ceRNA network. These results suggest that the crosstalk among circRNAs may play a crucial role in the development of SMG dysfunction in hypertension.

BACKGROUND: The widespread use of shared bicycles has increased the demand and sanitary requirements for shared bicycles. Previous studies have identified potentially pathogenic bacteria on the surfaces of shared bicycles, but fungal communities have not been investigated. METHODS: We sampled shared-bicycle handles and saddles from five selected locations in a metropolis (Chengdu, China, n = 98) and used surrounding air deposition samples as controls (n = 12). Full-length ITS sequencing and multiple bioinformatic analyses were utilized to reveal fungal community structures and differences. RESULTS: Aspergillus was dominant on both the handles and saddles of shared bicycles, and Alternaria and Cladosporium were the most abundant families in the air samples. Significant differences in fungal community structures were found among the three groups. The handle samples contained higher abundances of Aureobasidium melanogenum and Filobasidium magnum than the saddle and air samples. The saddle samples had a higher abundance of Cladosporium tenuissimum than the other two sample types (P < 0·05). A higher abundance of fungal animal pathogens on shared-bicycle surfaces than in air by FUNGuild (P < 0·05). Moreover, the co-occurrence network of fungi on handles was more stable than that on saddles. CONCLUSION: There were more potential pathogens, including Aspergillus pseudoglaucus, Aureobasidium melanogenum, Kazachstania pintolopesii, Filobasidium magnum, Candida tropicalis, and Malassezia globose were found on shared bicycles than in air, suggesting that hands should not contact mucous membrane after cycling, especially in susceptible individuals, and hygiene management of shared bicycles should be given more attention by relevant organizations worldwide.

Noninvasive positive-pressure ventilation (NPPV) is recognized as an effective adjuvant therapy for sleep-disordered breathing (SDB) in heart failure patients with reduced ejection fraction (HFrEF + SDB). In recent years, some studies have found that adaptive servo-ventilation (ASV) has a negative impact on survival, especially among patients with central sleep apnea (CSA), the use of which is controversial. This study aims to explore the effects of NPPV on cardiac function and survival in patients with sleep-disordered breathing and chronic congestive heart failure. This meta-analysis was based on literature searches of publications published before August 31, 2019, in the PubMed, EMBASE, Cochrane Library, and Web of Science databases. A total of 88 independent studies were summarized and compared, comprising a sampling of 19,259 subjects. Compared with the nontreatment group, treatment with ASV had no effect on all-cause mortality in patients with HFrEF + CSA (hazard ratio (HR) = 1.13 [0.84, 1.51]). Short-term treatment with ASV, e.g., 3-6 months, was significantly beneficial regarding event-free survival in patients with HFrEF + CSA (HR = 0.13 [0.04, 0.45]). Periodic short-term (e.g., 3-6 months) positive-pressure ventilation can significantly improve cardiac function, which is beneficial for the survival of patients with HFrEF + CSA. Attention should be paid to the length and period of treatment, as prolonged treatment may have negative effects.

OBJECTIVES: To evaluate the diagnostic performance of 1.5-T non-contrast MR coronary angiography (MRCA) for detection of coronary artery disease (CAD) using whole-heart imaging combined with volume-targeted imaging. METHODS: Forty-five patients scheduled for conventional coronary angiography (CAG) underwent 1.5-T free-breathing non-contrast steady-state free-precession MRCA, including whole-heart and subsequent three-vessel volume-targeted imaging. Coronary stenosis was evaluated as follows: (1) by whole-heart MRCA alone; (2) by combined MRCA (whole-heart plus volume-targeted images). The diagnostic performance for significant stenosis (≥ 50% diameter reduction) was evaluated and compared using CAG as a reference standard. RESULTS: Combined MRCA was completed in all 45 patients with a total acquisition time of 16.6 ± 3.3 min. The sensitivity, specificity, and accuracy of combined MRCA per patient were 97% (95% confidence interval 84-100%), 83% (52-98%), and 93% (82-98%), respectively. The areas under the receiver operating characteristic curve of combined MRCA were significantly higher than those of whole-heart MRCA on a per patient (0.97 versus 0.85, p = 0.0078) and per vessel (0.96 versus 0.86, p < 0.0001) basis. Compared with whole-heart MRCA, combined MRCA showed equally high sensitivity but significantly improved specificity on a per patient (83% versus 25%, p = 0.016) and per vessel (85% versus 50%, p < 0.0001) basis. CONCLUSIONS: 1.5-T non-contrast MRCA combining whole-heart and volume-targeted imaging can detect significant CAD with high sensitivity and moderate specificity. Combined MRCA significantly improves specificity compared with whole-heart imaging alone. KEY POINTS: ⢠1.5-T non-contrast MRCA with combined whole-heart and volume-targeted imaging can detect CAD with high sensitivity and moderate specificity comparable with coronary CTA. ⢠Compared with whole-heart imaging alone, combined imaging provides improved diagnostic accuracy, especially specificity.

OBJECTIVES: To investigate the diagnostic performance of 70-kVp stress dynamic myocardial CT perfusion (CTP) as a low-dose, one-stop cardiac CT examination in clinical application. MATERIALS AND METHODS: Consecutive symptomatic patients were prospectively recruited and scanned with stress dynamic myocardial CTP. The CTP phase with the best enhancement of the coronary arteries was selected and extracted as the CTP-derived single-phase coronary CT angiography (SP-CTA). The diagnostic performance of CTP and CTP+SP-CTA for functionally significant CAD was assessed. Invasive coronary angiography and fractional flow reserve were used as the reference standard for the myocardial ischemia evaluation. RESULTS: In total, 71 patients (43 men and 28 women; 63.6 ± 8.8 years old) underwent the stress dynamic myocardial CTP; 63 vessels (36.2%) from 42 of the patients (59.2%) were identified as causing ischemia. On a per-vessel basis, the sensitivity, specificity, PPV, NPV, and diagnostic accuracy for CTP and CTP+SP-CTA were 77.8%, 93.7%, 87.5%, 88.1%, and 87.9% and 84.1%, 93.7%, 88.3%, 91.2%, and 90.2%, respectively. The area under the curve (AUC) of CTP+SP-CTA (AUC = 0.963; 95%CI, 0.938-0.989) was significantly superior to that of CTP (AUC = 0.922; 95%CI, 0.880-0.964) and that of SP-CTA (AUC = 0.833; 95%CI, 0.765-0.900) alone (all p < 0.01). The mean radiation dose of the CTP examination was 3.8 ± 1.4 mSv. CONCLUSION: CTP-derived SP-CTA improved the diagnostic value of CTP. With a promising performance of myocardial ischemia detection and low radiation dose, the innovative low-dose, one-stop CTP examination is clinically feasible for patients who need to receive a myocardial perfusion assessment. KEY POINTS: ⢠Myocardial CTP performed well in the evaluation of hemodynamically significant CAD. ⢠CTP-derived single-phase CCTA improved the diagnostic value of CTP. ⢠The combined use of low-dose CTP and CTP-derived CCTA at 70 kVp is clinically feasible for CAD patients who need to receive a myocardial perfusion assessment.

BACKGROUND: The association between anxiety and atrial fibrillation (AF) remains unclear. Moreover, this association has rarely been studied in Chinese individuals aged 60 years or older. This study investigated the association between anxiety and AF in a community-based case-control study of older adult residents in urban China. METHODS: The cases and controls were from a community-based study conducted in the Jingansi community in Shanghai, China, between January 2010 and December 2012. A total of 3622 residents aged 60 years or older without severe vision, hearing, or speaking impairments were eligible to participate in the physical examinations and questionnaire survey. AF was assessed based on a previous physician's diagnosis, electrocardiogram, ambulatory electrocardiogram, or echocardiogram. Anxiety was evaluated using the Zung Self-Rating Anxiety Scale (ZSAS). Using the AF group as a reference, the control group consisted of randomly selected age- and sex-matched individuals in a 1:5 ratio (case:control = 1:5). The association between anxiety and AF in the AF group and the multifactor-matched control group was explored using logistic regression. RESULTS: In the AF and control groups, after adjusting for a history of coronary heart disease, valvular heart disease, hypertension, stroke, hyperlipidemia, and diabetes, as well as depression score, ZSAS scores (odds ratio 1.07; 95% confidence interval 1.02-1.12; p = 0.003), and anxiety symptoms (odds ratio 3.94; 95% confidence interval 1.06-14.70; p = 0.041) were associated with AF. CONCLUSIONS: Anxiety symptoms were associated with AF in a Chinese older population. This suggests that older adults who have anxiety symptoms may need psychological intervention or treatment in daily life and care.

Hedgehog plays an important role in a wide range of physiological and pathological conditions. Paracrine activation of Hedgehog pathway in stromal cells increases the expression of VEGF, which promotes neovascularization in colorectal cancer and ultimately the growth of colorectal cancer. Berberine (BBR) has anticancer activity. In this study we investigated whether BBR inhibited the growth of colon cancer through suppressing the paracrine sonic hedgehog (SHH) signaling in vitro and in vivo. We showed that BBR (1-10 µM) dose-dependently inhibited the secretion and expression of SHH protein in HT-29 and SW480 cells. BBR did not influence the transcription of SHH, but promoted the degradation of SHH mRNA, thus decreased the SHH mRNA expression in the colorectal cancer cells. In nude mice bearing HT-29 xenograft, oral administration of BBR (100 mg · kg-1 · d-1) or a positive control drug GDC-0449 (100 mg · kg-1 · d-1) for 4 weeks markedly suppressed the growth of HT-29 tumor with BBR exhibiting a better antitumor efficacy. The tumor growth inhibition caused by BBR or GDC-0449 was comparable to their respective inhibitory effect on the mouse-specific Gli mRNA expression in the tumor. However, BBR (20 µM) did not affect the expression of human transcription factor Gli1 mRNA in HT-29 and SW480 cells. In conclusion, BBR promotes the degradation of SHH mRNA in colorectal cancer cells, interrupting the paracrine Hedgehog signaling pathway activity thus suppresses the colorectal cancer growth. This study reveals a novel molecular mechanism underlying the anticancer action of BBR.

Sepsis is the most common cause of death in intensive care units. This study investigated the circular RNA (circRNA) and mRNA expression profiles and functional networks of the aortic tissue in sepsis. We established a lipopolysaccharide (LPS)-induced rat sepsis model. High-throughput sequencing was performed on the aorta tissue to identify differentially expressed (DE) circRNAs and mRNAs, which were validated by real-time quantitative polymerase chain reaction (RT-qPCR). Bioinformatic analysis was carried out and coding and non-coding co-expression (CNC) and competing endogenous RNA (ceRNA) regulatory networks were constructed to investigate the mechanisms. In total, 373 up-regulated and 428 down-regulated circRNAs and 2063 up-regulated and 2903 down-regulated mRNAs were identified. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses of mRNAs showed that the down-regulated genes were mainly enriched in the process of energy generation. CNC and ceRNA regulatory networks were constructed with seven DE circRNAs. The results of functional enrichment analysis of CNC target genes revealed the important role of circRNAs in inflammatory response. The ceRNA network also highlighted the significant enrichment in calcium signalling pathway. Significant alterations in circRNAs and mRNAs were observed in the aortic tissue of septic rats. In addition, CNC and ceRNA networks were established.

Berberine (BBR), a small alkaloid, is used as a hypoglycemic agent in China. Stachyose (Sta), a Rehmannia glutinosa oligosaccharide, acts as a prebiotic. This study aimed to evaluate whether BBR combined with Sta produced better glycometabolism than BBR alone, and explored the effects on gut microbiota and metabolomics. Type-2 diabetic db/db mice were administered BBR (100 mg/kg), Sta (200 mg/kg), or both by gavage once daily. Glucose metabolism, the balance of α- and ß-cells, and mucin-2 expression were ameliorated by combined treatment of BBR and Sta, with stronger effects than upon treatment with BBR alone. The microbial diversity and richness were altered after combined treatment and after treatment with BBR alone. The abundance of Akkermansia muciniphila was increased by combined treatment compared to treatment with BBR alone, while the levels of the metabolite all-trans-heptaprenyl diphosphate were decreased and the levels of fumaric acid were increased, which both showed a strong correlation with A. muciniphila. In summary, BBR combined with Sta produced better glycometabolism than BBR alone through modulating gut microbiota and fecal metabolomics, and may aid in the development of a novel pharmaceutical strategy for treating Type 2 diabetes mellitus.
