Semantics-Aware Spatial-Temporal Binaries for Cross-Modal Video Retrieval

With the current exponential growth of video-based social networks, video retrieval using natural language is receiving ever-increasing attention. Most existing approaches tackle this task by extracting individual frame-level spatial features to represent the whole video, while ignoring visual pattern consistencies and intrinsic temporal relationships across different frames. Furthermore, the semantic correspondence between natural language queries and person-centric actions in videos has not been fully explored. To address these problems, we propose a novel binary representation learning framework, named Semanticsaware Spatial-temporal Binaries (S(2)Bin), which simultaneously considers spatial-temporal context and semantic relationships for cross-modal video retrieval. By exploiting the semantic relationships between two modalities, S(2)Bin can efficiently and effectively generate binary codes for both videos and texts. In addition, we adopt an iterative optimization scheme to learn deep encoding functions with attribute-guided stochastic training. We evaluate our model on three video datasets and the experimental results demonstrate that S(2)Bin outperforms the state-of-the-art methods in terms of various cross-modal video retrieval tasks

Allium vegetable consumption and health: An umbrella review of meta‐analyses of multiple health outcomes

Previously, our meta‐analysis and other studies have suggested that allium vegetable consumption is beneficial for health, but no umbrella review has been conducted to assess the evidence of the various health benefits of allium vegetable consumption. Therefore, we conducted this umbrella review on this topic. This umbrella review included a total of 16 meta‐analyses with 50 unique outcomes. The most beneficial cancer‐related outcome was shown for gastric cancer (risk ratio 0.78; 95% confidence interval [CI] 0.67–0.91). In addition, only 8 weeks of garlic consumption significantly decreased serum total cholesterol (weighted mean differences −17.20 mg/dl; 95% CI −23.10 to −11.30), and patients with dyslipidemia who consumed garlic experienced more benefits than the whole population. Diabetic patients with longer durations of garlic intake experienced more benefits in terms of fasting blood glucose (FBG), HbA1c, and serum fructosamine than healthy participants, and garlic intake was associated with blood pressure reduction in hypertensive patients but not in normotensive participants. Limited side effects of garlic, such as garlic odor and gastrointestinal complaints, were reported among the included meta‐analyses. Our results suggested that allium vegetables might be beneficial for cancer prevention. In particular, garlic was comparatively safe and is recommended as a long‐term dietary component for patients with dyslipidemia, diabetes, and hypertension

The effect of switch therapy to tenofovir versus entecavir maintenance on recurrence of hepatocellular carcinoma after surgery (SWITE): study protocol for a randomized controlled trial

Abstract Background Antiviral therapy has been reported to be associated with lower recurrence rate of hepatocellular carcinoma (HCC) for patients with hepatitis B virus (HBV) infection. While entecavir (ETV) and tenofovir disoproxil fumarate (TDF) were both recommended as first-line therapies for HBV patients, recent retrospective studies proposed a lower incidence rate of HCC occurrence or recurrence in those receiving TDF compared ETV. However, the survival benefits of switching to TDF therapy after prolonged ETV treatment before surgery remain uncertain. We delineate the rationale and design of SWITE, a randomized, open-label, phase III trial contrasting TDF switch therapy versus ETV maintenance in HBV-related HCC patients. Methods and analysis This is a prospective, randomized, controlled, single-center study with two parallel groups of patients with HBV-related HCC who have received long-term ETV therapy before surgery. West China Hospital will enroll 238 patients, randomized in a 1:1 ratio to TDF switch therapy or ETV maintenance after surgery. The primary endpoint of this study is 3-year recurrence free survival (RFS), with the secondary endpoint being 3-year overall survival (OS) after curative surgery of HCC. Safety events will be diligently recorded. Ethics and dissemination The study protocol aligns with the ethical guidelines of the 1975 Declaration of Helsinki. It was approved by ethics committee of West China Hospital (approval number: 2022-074) and was registered with chictr.org.cn (chiCTR2200057867). Informed consent will be obtained from all participants. The results of this trial will be published in peer-reviewed journals and presentations at national and international conferences relevant to this topic. Trial registration chiCTR2200057867 . Date of registration is March 20 2022

Integrating Network Pharmacology with Molecular Docking to Unravel the Active Compounds and Potential Mechanism of Simiao Pill Treating Rheumatoid Arthritis

Objective. To explore the main components and unravel the potential mechanism of simiao pill (SM) on rheumatoid arthritis (RA) based on network pharmacological analysis and molecular docking. Methods. Related compounds were obtained from TCMSP and BATMAN-TCM database. Oral bioavailability and drug-likeness were then screened by using absorption, distribution, metabolism, and excretion (ADME) criteria. Additionally, target genes related to RA were acquired from GeneCards and OMIM database. Correlations about SM-RA, compounds-targets, and pathways-targets-compounds were visualized through Cytoscape 3.7.1. The protein-protein interaction (PPI) network was constructed by STRING. Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed via R packages. Molecular docking analysis was constructed by the Molecular Operating Environment (MOE). Results. A total of 72 potential compounds and 77 associated targets of SM were identified. The compounds-targets network analysis indicated that the 6 compounds, including quercetin, kaempferol, baicalein, wogonin, beta-sitosterol, and eugenol, were linked to ≥10 target genes, and the 10 target genes (PTGS1, ESR1, AR, PGR, CHRM3, PPARG, CHRM2, BCL2, CASP3, and RELA) were core target genes in the network. Enrichment analysis indicated that PI3K-Akt, TNF, and IL-17 signaling pathway may be a critical signaling pathway in the network pharmacology. Molecular docking showed that quercetin, kaempferol, baicalein, and wogonin have good binding activity with IL6, VEGFA, EGFR, and NFKBIA targets. Conclusion. The integrative investigation based on bioinformatics/network topology strategy may elaborate on the multicomponent synergy mechanisms of SM against RA and provide the way out to develop new combination medicines for RA

Objective<p>Daytime cognitive impairment is an essential symptom of primary insomnia (PI). However, the underlying neural substrate remains largely unknown. Many studies have shown that the right anterior insula (rAI) as a key node of salience network (SN) plays a critical role in switching between the executive control network (ECN) and the default mode network (DMN) for better performance of cognitively demanding tasks. Aberrant effective connectivity (directional functional connectivity) of rAI with ECN or DMN may be one reason for daytime cognitive impairment in PI patients.
