Heart rate is a crucial indicator of human health with significant physiological importance. Traditional contact methods for measuring heart rate, such as electrocardiograph or wristbands, may not always meet the need for convenient health monitoring. Remote photoplethysmography (rPPG) provides a non-contact method for measuring heart rate and other physiological indicators by analyzing blood volume pulse signals. This approach is non-invasive, does not require direct contact, and allows for long-term healthcare monitoring. Deep learning has emerged as a powerful tool for processing complex image and video data, and has been increasingly employed to extract heart rate signals remotely. This article reviewed the latest research advancements in rPPG-based heart rate measurement using deep learning, summarized available public datasets, and explored future research directions and potential advancements in non-contact heart rate measurement.

Objective To investigate the risk factor for adverse events(AEs)after non-sedated esophagogastroduodenoscopy(EGD).Methods The data on clinical manifestations,adverse events after non-sedated EGD and common risk factors were collected and retrospectively analyzed with statistical methods in patients who underwent non-sedated EGD from May 2018 to June 2019.These patients were divided into AEs group and non-AEs group.Results Of 2 384 patients,57.67%(1 375/2 384)presented with nausea,12.79%(305/2 384)vomiting,and 5.79%(138/2 384)presented with pharyngalgia.Multivariate Logistic regression analysis was performed.Advanced age(≥65 years old)(OR=0.683,95%CI:0.506-0.921)was protective factors for nausea after non-sedated EGD.Hypertension(OR=1.361,95%CI:1.026-1.806),overweight(OR=1.399,95%CI:1.154-1.695),obesity(OR=2.594,95%CI:1.760-3.823)and inspection duration>15 min(OR=3.107,95%CI:2.296-4.206)were independent risk factors for nausea after non-sedated EGD.Advanced age(OR=0.393,95%CI:0.221-0.699)and imported equipment(OR=0.697,95%CI:0.546-0.890)were protective factors for vomiting after non-sedated EGD.Moreover,inspection duration>15 min(OR=1.641,95%CI:1.008-2.699)was independent risk factors for vomiting after non-sedated EGD.There was no difference in success rate of non-sedated EGD between two groups(P<0.05).Conclusion Hypertension,overweight and obesity were independent risk factors for nausea after non-sedated EGD.The advanced age and imported equipment were protective factors for vomiting after non-sedated EGD.In addition,inspection duration over 15 min is a risk factor for AEs such as nausea and vomiting after nonsedative EGD.Whether AEs occurred or not is non-related to success rate of non-sedated EGD.

Gastric cancer is a common clinical tumor,and its incidence and mortality rates rank among the top of malignant tumors.Helicobacter pylori(Hp)is an important carcinogenic factor for gastric cancer.Studies have found that in addition to Hp,other microorganisms in the stomach also play a key role in the progression of gastric cancer.The composition and diversity of the gastric microbiota vary significantly under different gastric disease conditions,which may affect the progression of gastric cancer.Hp can induce gastric epithelial inflammation and oxidative stress through various virulence factors,thereby promoting the occurrence of gastric cancer.Non-Hp microorganisms can be involved in the process of gastric cancer through pathways such as metabolic changes and immune regulation.In recent years,with the development of high-throughput sequencing technology,the complexity of gastric microbiota has gradually been revealed,which provides new insights for the early warning and intervention of gastric cancer.This article comprehensively review the role of gastric microbiota in the progression of gastric cancer.

ObjectiveTo investigate the effect of modified Baduanjin exercise, as an rehabilitation exercise, on cardiopulmonary function, motor function and activities of daily living in patients with stroke. MethodsFrom January to September, 2023, 42 stroke patients in the Nanjing Qixia District Hospital were randomly divided into control group (n = 21) and experimental group (n = 21). The control group received routine rehabilitation, and the experimental group received modified Baduanjin exercise in addition, for four weeks. They were assessed with peak oxygen uptake (VO_2peak), anaerobic threshold (AT), peak oxygen pulse (VO_2peak/HR), forced vital capacity (FVC), forced expiratory volume in the first second (FEV₁), peak expiratory flow (PEF), Fugl-Meyer Assessment-upper extremities (FMA-UE), Berg Balance Scale (BBS) and modified Barthel Index (MBI) before and after intervention. ResultsVO_2peak, AT, and the scores of FMA-UE, BBS and MBI improved in the control group after intervention (|t| > 2.256, |Z| > 2.936, P < 0.05); while VO_2peak, AT, VO_2peak/HR, FVC, FEV₁, PEF, and the scores of FMA-UE, BBS and MBI improved in the experimental group (|t| > 4.390, |Z| > 3.451, P < 0.001); and all the indexes were better in the experimental group than in the control group (|t| > 4.136，|Z| > 2.751，P < 0.01), except the scores of BBS and MBI. ConclusionModified Baduanjin exercise can improve the cardiopulmonary function and upper limb motor function for stroke patients.

Objective:To explore the potential pathogenesis of exosome-mediated polymyositis/dermatomyositis (PM/DM) through multi-omics combined with bioinformatic analysis approach and to identify potential new targets for the diagnosis and treatment of PM/DM.Methods:Collect serum exosome samples from PM/DM patients and healthy individuals who underwent physical examination in Wuxi Second People′s Hospital from January 2021 to June 2023. HiSeq high-throughput sequencing technology and iTRAQ quantitative proteomics techniques were used to perform a sequencing analysis of miRNA and protein components in serum exosomes from patients with PM/DM and healthy control. R language was adapted to conduct the limma differential analysis, gene ontology (GO), Kyoto encyclopedia of genes and genomes (KEGG), gene set enrichment analysis (GSEA) functional analysis, and immunological correlation analysis. Based on these analysis, we identified core genes and established a miRNA-target gene-transcription factor co-expression molecular network. Subsequently, we employed quantitative real-time PCR (qRT-PCR) to experimentally validate the core genes. Data analysis was performed using t-test statistical analysis and receiver operating characteristic (ROC) curves were plotted to evaluate the test efficacy of the core genes. Results:Initially, 42 up-regulated differential proteins and 61 DEP down-regulated differential proteins, as well as 22 up-regulated differential miRNAs and 19 down-regulated miRNAs were screened, and 7 core genes, 13 associated differential miRNAs, and 4 transcription factors were finally identified. Based on the functional analysis we concluded that the core genes CTSG, MPO, H1-5 involved in the formation of neutrophil extracellular trap network, NF-κB pathway and other inflammation-related pathways might play an important role in exosome-mediated PM/DM pathogenesis. Immune cells such as mast cells, immature dendritic cells, natural killer cells, regulatory T cells, and helper T cells 2 were expressed to a higher extent in the disease. In the t-test, MPO [(1.08 ±0.47) vs. (2.05 ±0.62), t=-3.50, P=0.004], CTSG [(1.11 ±0.51 ) vs. (2.27 ±1.10 ), t=-2.72, P=0.022], and H1-5 [(1.03 ±0.25) vs. (1.81 ±0.73), t=-2.89, P=0.019] showed statistically significant differences. In the ROC curve analysis, MPO[AUC(95% CI): 0.92(0.78, 1)], CTSG [AUC(95% CI): 0.81(0.59, 1)], and H1-5 (AUC (95% CI)= 0.84(0.64, 1)] indicated that the three core genes had good accuracy. Conclusion:We identified the key differential molecules in serum exosomes of patients with PM/DM, and constructed a regulatory network of miRNA-target gene-transcription factor, and determined that the pathogenic mechanism of PM/DM was mediated by serum exosomes was mediated through the formation of neutrophil extracellular trapping nets and the NF-κB pathway. CTSG, MPO, and H1-5 are the core genes in the these pathways, and their related miRNAs and transcription factors have been identified, which may become potential targets and biomarkers for the diagnosis and treatment of PM/DM.
