Mechanisms and therapeutic potential of chinonin in nervous system diseases.

The flavonoid compound chinonin is one of the main active components of Rhizoma anemarrhena with multiple activities, including anti-inflammatory and antioxidant properties, protection of mitochondrial function and regulation of immunity. In this paper, we reviewed recent research progress on the protective effect of chinonin on brain injury in neurological diseases. "Chinonin" OR "Mangiferin" AND "Nervous system diseases" OR "Neuroprotection" was used as the terms for search in PumMed. After discarding duplicated and irrelevant articles, a total of 23 articles relevant to chinonin published between 2012 and 2023 were identified in our study.

Prognostic Value of Coronary Microvascular Dysfunction Assessed by Coronary Angiography-Derived Index of Microcirculatory Resistance in Patients With ST-Segment Elevation Myocardial Infarction.

BACKGROUND: CaIMR is proposed as a novel angiographic index designed to assess microcirculation without the need for pressure wires or hyperemic agents. We aimed to investigate the impact of caIMR on predicting clinical outcomes in STEMI patients. METHODS: One hundred and forty patients with STEMI who received PCI in Putuo Hospital of Shanghai from October 2021 to September 2022 were categorized into CMD and non-CMD groups according to the caIMR value. The baseline information, patient-related examinations, and the occurrence of MACE at the 12-month follow-up were collected to investigate risk factors in patients with STEMI. RESULTS: We divided 140 patients with STEMI enrolled into two groups according to caIMR results, including 61 patients diagnosed with CMD and 79 patients diagnosed with non-CMD. A total of 21 MACE occurred during the 1 year of follow-up. Compared with non-CMD group, patients with CMD showed a significantly higher risk of MACE. A multivariate Cox regression model was conducted for the patients, and it was found thatcaIMR was a significant predictor of prognosis in STEMI patients (HR: 8.921). Patients with CMD were divided into culprit vascular CMD and non-culprit vascular CMD, and the result found that culprit vascular CMD was associated with the incidence of MACE (OR: 4.75) and heart failure (OR: 7.50). CONCLUSION: CaIMR is a strong predictor of clinical outcomes and can provide an objective risk stratification for patients with STEMI. There is a strong correlation among leukocyte index, the use of furosemide, Killips classification, and clinical outcomes.

Evans syndrome suggests disease progression in lung adenocarcinoma.

We admitted a 60-year-old male patient diagnosed with lung adenocarcinoma who had a shrinking lung cancer mass after radiotherapy and 6 cycles of chemotherapy, but developed facial inflammation 2 weeks after the end of the final chemotherapy treatment, and was admitted to the hospital with anemia and thrombocytopenia, and diagnosed with Evans syndrome, and brain metastasis of lung cancer was found in the course of the consultation, which suggested disease progression. Evans syndrome was seen as a paraneoplastic syndrome.

Development of an artificial intelligence-based multimodal model for assisting in the diagnosis of necrotizing enterocolitis in newborns: a retrospective study.

Objective: The purpose of this study is to develop a multimodal model based on artificial intelligence to assist clinical doctors in the early diagnosis of necrotizing enterocolitis in newborns. Methods: This study is a retrospective study that collected the initial laboratory test results and abdominal x-ray image data of newborns (non-NEC, NEC) admitted to our hospital from January 2022 to January 2024.A multimodal model was developed to differentiate multimodal data, trained on the training dataset, and evaluated on the validation dataset. The interpretability was enhanced by incorporating the Gradient-weighted Class Activation Mapping (GradCAM) analysis to analyze the attention mechanism of the multimodal model, and finally compared and evaluated with clinical doctors on external datasets. Results: The dataset constructed in this study included 11,016 laboratory examination data from 408 children and 408 image data. When applied to the validation dataset, the area under the curve was 0.91, and the accuracy was 0.94. The GradCAM analysis shows that the model's attention is focused on the fixed dilatation of the intestinal folds, intestinal wall edema, interintestinal gas, and portal venous gas. External validation demonstrated that the multimodal model had comparable accuracy to pediatric doctors with ten years of clinical experience in identification. Conclusion: The multimodal model we developed can assist doctors in early and accurate diagnosis of NEC, providing a new approach for assisting diagnosis in underdeveloped medical areas.

The Chinese version of the Ohkuma questionnaire: reliability analysis and diagnostic value.

BACKGROUND: While the Ohkuma questionnaire is a simple, reliable, and easy-to-use tool to assess dysphagia, none of its versions can be used by the Chinese population. OBJECTIVE: The purpose of this study was to evaluate the internal consistency, reliability and clinical validity of a newly made Chinese version of the Ohkuma questionnaire, and to provide some objective basis for its application in screening dysphagia. MATERIALS AND METHODS: From September 21 to June 2022, 96 patients with dysphagia and 89 asymptomatic subjects were recruited from three hospitals in China to form an observation and a control group, respectively. All subjects completed the Ohkuma questionnaire, Eating Assessment Tool-10, and a Video Fluoroscopy Study of Swallowing. RESULTS: The Cronbach's α coefficient measured in the questionnaire was 0.867, indicating acceptable internal reliability. The analysis of variance generated four main factors to be assessed, showing a good aggregation effectiveness of the questionnaire. The AVE square root values of three factors were greater than the maximum absolute value of the correlation coefficients between factors, indicating good differentiation effectiveness. The sensitivity and specificity scores, together with the positive and negative likelihood as well as diagnostic odds ratios indicate a good reactivity of the questionnaire. Lastly, after adjusting for age and sex, the results of the stepwise linear regression analysis showed that there was a significant positive correlation between the Ohkuma questionnaire and the penetration aspiration scale. CONCLUSIONS: The Chinese version of the Ohkuma questionnaire has good reliability and validity, and can be used as a rapid and effective screening tool for dysphagia.

Long-Term Prognosis of Patients Undergoing Percutaneous Coronary Intervention: The Impact of Serum Creatinine Levels on All-Cause Mortality.

BACKGROUND The correlation between serum creatinine levels and the long-term prognosis of patients undergoing percutaneous coronary intervention (PCI) has not yet been systematically investigated. This study aimed to evaluate the association between long-term prognosis and serum creatinine levels in patients after PCI. MATERIAL AND METHODS This was an observational cohort study of 2533 patients who received PCI and completed serum creatinine and other tests in China. The study's primary prognostic indicators were the frequency of clinical adverse events, all-cause death, cardiac death, acute myocardial infarction, and stroke. All-cause death referred to death from all causes during the follow-up period, whereas cardiac death was death due to cardiac injury resulting in severe cardiac dysfunction or failure. Clinical events included death, ischemia, and stroke. Yao et al completed the entire study and uploaded the data to the DATADRYAD website. We used only this data for secondary analysis. RESULTS The study involved 2533 participants, with a mean age of 59.9±11.1 years and a median follow-up of 29.8 months. The analysis, controlling for confounding factors, revealed a positive correlation between serum creatinine and all-cause death (OR: 2.178, 95% CI: 1.317-3.603, P<0.05), which was confirmed by the results of sensitivity analysis (P for trend <0.05). However, no direct linear correlation was found between serum creatinine and acute myocardial infarction, cardiac death, or stroke. CONCLUSIONS There was a linear correlation between serum creatinine and all-cause death in the long-term prognosis of patients after PCI, independent of acute myocardial infarction, cardiac death, and stroke.

Exogenous methyl jasmonate enhanced kenaf (Hibiscus cannabinus) tolerance against lead (Pb) toxicity by improving antioxidant capacity and osmoregulators.

In this study, the effects of exogenous methyl jasmonate (MeJA) on metal uptake and its ability to attenuate metal toxicity in kenaf plants under Pb stress were investigated. The experiment was conducted with five different MeJA concentrations (0, 40, 80, 160, and 320 µM) as a foilar application to kenaf plants exposed to 200 µM Pb stress. The results revealed that pretreatmen of MeJA significantly increased plant dry weight, plant height, and root architecture at all concentrations tested, with the most significant increase at 320 µM. Foliar application of MeJA at 160 µM and 320 µM increased the Pb concentrations in leaves and stems as well as the translocation factor (TF) from root to leaf. However, the bioaccumulation factor in the shoot initially decreased and then increased with increasing MeJA concentration. By increasing enzymatic (SOD, POD, and CAT) and non-enzymatic (AsA and non-protein thiols) antioxidants, MeJA pretreatment decreased lipid peroxidation, O2- and H2O2 accumulation and recovered photosynthetic pigment content under Pb stress. Increased osmolytes (proline, sugar, and starch) and protein content after MeJA pretreatment under Pb stress restore cellular homeostasis and improved kenaf tolerance. Our results suggest that MeJA pretreatment modifies the antioxidant machinery of kenaf and inhibits stress-related processes that cause lipid peroxidation, hence enhancing plant tolerance to Pb stress.

STAT3 mediates ECM stiffness-dependent progression in ovarian cancer.

The treatment of ovarian cancer remains a medical challenge and its malignant progression is connected with obvious changes in both tissue and cell stiffness. However, the accurate mechanical-responsive molecules and mechanism remains unclear in ovarian cancer. Based on our previous results combined with the crucial regulatory role of STAT3 in the malignant progression of various cancer types, we want to investigate the relationship between STAT3 and matrix stiffness in ovarian cancer and further explore the potential mechanisms. Collagen-coated polyacrylamide gels (1, 6, and 60 kPa) were prepared to mimic soft or hard matrix stiffness. Western blotting, qRT-PCR, flow cytometry, IHC, EdU assays, and TEM were used to evaluate the effect of STAT3 in vitro under different matrix stiffnesses. Furthermore, a BALB/c nude mouse model was established to assess the relationship in vivo. Our results confirmed the differential expression of STAT3/p-STAT3 not only in normal and malignant ovarian tissues but also under different matrix stiffnesses. Furthermore, we verified that STAT3 was a mechanically responsive gene both in vitro and in vivo, and the mechanical response was carried out by altering the migration-related molecules (TNFAIP1) and adhesion-related molecules (LPXN, CNN3). The novel findings suggest that STAT3, a potential therapeutic target for clinical diagnosis and treatment, is a mechanically responsive gene that responds to matrix stiffness, particularly regulation in migration and adhesion in the progression of ovarian cancer.

Effect of Interdisciplinary Collaboration in Emergency Nursing Using the SWOT Model on Acute Myocardial Infarction.

Objective: To explore the effect of interdisciplinary collaboration in emergency nursing using the strengths-weaknesses-opportunities-threats (SWOT) model on patients with acute myocardial infarction (AMI). Methods: Eighty AMI patients undergoing rescue treatment at Affiliated Hospital of Inner Mongolia Medical University from October 2020 to June 2022 were selected and randomly divided into the SWOT group and the control group. The patients in the control group received routine emergency nursing intervention, while those in the SWOT group were given interdisciplinary collaboration using the SWOT model. The emergency-related time, cardiac function indicators, incidence of adverse events, quality of life, and nursing satisfaction were compared between the two groups. Results: The waiting time, triage assessment time, electrocardiogram examination time, emergency treatment time, PCI duration and ICU stay time in SWOT group were significantly shorter than those in control group. The left ventricular end-systolic diameter (LVESd), left ventricular end-diastolic diameter (LVEDd), and left ventricular ejection fraction (LVEF) in the SWOT group were all superior to those in the control group. The SWOT group had a significantly lower incidence rate of adverse events than the control group. The quality of life scores of SWOT group were higher than those of control group. The nursing satisfaction in the SWOT group was higher than that in the control group. Conclusion: Interdisciplinary collaboration using the SWOT model for AMI patients can effectively shorten the rescue time, ameliorate cardiac function indicators, reduce the risk of adverse events, improve patients' quality of life, and enhance nursing satisfaction.

CPU-GPU-coupled acceleration method for point flux calculation in Monte Carlo particle transport.

In Monte Carlo particle transport simulations, point flux tallying is a variance reduction technique that performs well with small detectors and finds broad application in source-detector problems and local point dose calculations. However, its use in large-scale point flux tallying computation adds substantial computational time. To address this issue, we propose a CPU-GPU-coupled acceleration method, which separates the complex logic and computationally intensive parts of particle transport calculation and assigns them to the CPU and GPU, respectively. This proposed method greatly enhances the efficiency of large-scale point flux tallies, providing significant convenience for subsequent dose calculations and other related steps. We validated our method by comparing the performance of a pure CPU program with our CPU-GPU accelerated program using the NUREG/CR-6115 PWR benchmark problem. The results indicate identical outcomes for photon point flux estimation, with the accelerated program being ~50 times faster.

Chromatin binding protein HMGN1 promotes HBV cccDNA transcription and replication by regulating the phosphorylation of histone 3.

BACKGROUND AND AIMS: Direct elimination of cccDNA remains a formidable obstacle due to the persistent and stable presence of cccDNA in hepatocyte nuclei. The silencing of cccDNA transcription enduringly is one of alternative strategies in the treatment of hepatitis B. Protein binding to cccDNA plays an important role in its transcriptional regulation; thus, the identification of key factors involved in this process is of great importance. APPROACHES AND RESULTS: In the present study, high mobility group nucleosome binding domain 1 (HMGN1) was screened out based on our biotin-avidin enrichment system. First, chromatin immunoprecipitation and fluorescent in situ hybridization assays confirmed the binding of HMGN1 with cccDNA in the nucleus. Second, functional experiments in HBV-infected cells showed that the promoting effect of HMGN1 on HBV transcription and replication depended on the functional region of the nucleosomal binding domain, while transfection of the HMGN1 mutant showed no influence on HBV compared with the vector. Third, further mechanistic exploration revealed that the silencing of HMGN1 increased the level of phosphorylase CLK2 and promoted H3 phosphorylation causing the reduced accessibility of cccDNA. Moreover, silenced HMGN1 was mimicked in HBV (r) cccDNA mouse model of HBV infection in vivo. The results showed that silencing HMGN1 inhibited HBV replication in vivo. CONCLUSIONS: In summary, our study identified that a host protein can bind to cccDNA and promote its transcription, providing a candidate strategy for anti-HBV targeting to interfere with the transcriptional activity of cccDNA microchromosomes.

Intercomparison of neutron personal dose equivalent measured by thermoluminescence dosimeters.

An intercomparison of neutron personal dose equivalent measured by the Harshaw thermoluminescence neutron dosimeters (TLDs) between the National Institute of Metrology of China (NIM) and the Institute for Nuclear Science and Technology of Vietnam (INST) was performed. Three sets of TLDs (each set consisting of five TLDs) were prepared for each laboratory. Each set was then irradiated to the corresponding same nominal standard value of neutron personal dose equivalent, Hp(10)n-stdi, of 1.0, 2.0, and 3.0 mSv, respectively at these two laboratories. The irradiated TLDs were then read-out at the INST using the Harshaw 4500-type TLD reader to obtain neutron personal dose equivalents at the NIM, Hp(10)n-NIMi and at the INST, Hp(10)n-INSTi, which are corresponding to different values of Hp(10)n-stdi. The TLDs' responses to different scattered components of neutrons in these two fields are also discussed. Comparisons between the corresponding pair values of Hp(10)n-NIMi and Hp(10)n-INSTi show good agreements within 10% with the standard uncertainty of 12.5% (k = 1). The measured values of Hp(10)n-NIMi and Hp(10)n-INSTi are satisfied the Trumpet curve criteria. This implies that the TLDs can be used for safety assessment of occupational neutron personal dose equivalents. This intercomparison result also confirms the capabilities of these two laboratories (i.e., NIM, INST) on deliveries of neutron personal dose equivalent standard values for calibrations.

The influence of Hyssopus cuspidatus Boriss extract on lipid mediators metabolism network in asthmatic mice.

Current drugs do not provide an absolute cure or modify the course of asthma. Hyssopus cuspidatus Boriss extract (SXCF) has been used as Uyghur medicine for several years to treat bronchial asthma. However, very limited research has been conducted on the therapeutic mechanisms of SXCF. Disruptions in the metabolic network of lipid mediators (LMs) are closely linked to the development of asthma. Here, we explored the therapeutic mechanism of SXCF in asthma based on the metabolic network of LMs, aiming to contribute to the understanding of SXCF in asthma treatment at the molecular level. The UHPLC-MRM strategy was used for the quantitative detection of LMs in the lung tissue and in the peripheral circulatory system (serum). ELISA was used to detect IgE in serum and cytokines in BALF. The lung tissue sections were stained with H&E to observe the infiltration of inflammatory cells, and behavioural changes in mice were observed and recorded throughout the animal experiment. In contrast to the asthma group, the opposite result was observed in the SXCF groups, where the perturbed LMs metabolic network was partly restored in a dose-dependent manner with a significant elevation of anti-inflammatory metabolites, while pro-inflammatory lipids were decreased. As significant downregulation of IgE and pro-inflammatory cytokines was observed, IgE and cytokines analysis also supported the anti-inflammatory effects of SXCF. It was also noticed that SXCF treatment reduced the number of coughs and decreased the inflammatory cell infiltration around the bronchus in mice. These results suggested that SXCF has a significant ameliorative effect on ovalbumin (OVA)-induced asthma. The modulation of LMs is a possible underlying mechanism of the SXCF effects.

A comprehensive review on pollution status and associated health risk assessment of human exposure to selected heavy metals in road dust across different cities of the world.

In order to expound on the present situation and potential risk of road dust heavy metals in major cities, a total of 114 literatures mainly over the past two decades, involving more than 5000 sampling sites in 61 cities of 21 countries, were screened through the collection and analysis of research papers. The concentration, sources, distribution, health risk, sample collection, and analytical methods of heavy metal research on road dust in cities around the world are summarized. The results show that Cd, Zn, and Cu in many urban road dusts in the world are higher than the grade II of the Chinese maximum allowable concentration of potentially toxic elements in the soil. Geo-accumulation index values show that Pb > Cd > Zn > Cu had the highest contamination levels. Hazard index assessment indicates Pb and Cr had the highest potential health risk, especially for children in which ingestion was found as the main exposure pathway. Moreover, through comparative analysis, it is found that some pollutants are higher in developed and industrialized cities and transport (53%) followed by industrial emissions (35%) provide the major contributions to the sources of heavy metals.

Ciliatoside A, isolated from Peristrophe japonica, inhibits HBsAg expression and cccDNA transcription by inducing autophagy.

Hepatitis B surface antigen (HBsAg) loss and seroconversion are considered as an end point of a functional cure. Therefore, it is crucial to find new agents which could efficiently decrease HBsAg. Traditional herbal plants have been considered as an important source of new hepatitis B drugs development for their extensive use in antimicrobial and anti-inflammation. In this study, Peristrophe japonica, which could remarkably reduce HBsAg in the supernatant of HepG2.2.15 cells, was screened out for further extraction. Here, an active ethyl acetate fraction of Peristrophe japonica containing 34 sub-fractions was extracted. Subsequently, the monomeric compound Ciliatoside A was isolated and identified as a potential antiviral reagent with low cytotoxicity from Fraction 30. Ciliatoside A exhibited strong inhibition on intracellular and circulating HBsAg and HBV RNAs in HBV-infected cells and an HBV recombinant-cccDNA mouse model. The mechanistic study revealed that Ciliatoside A exhibited a potent anti-HBV effect through inducing autophagy-lysosomal pathway to autophagic degradation of HBc by activating AMPK-ULK1 axis and inhibiting mTOR activation. In summary, we have identified a novel antiviral compound Ciliatoside A isolated from Peristrophe japonica. This study may provide important direction and new ideas for the discovery of hepatitis B cure drugs.

Yanghe decoction attenuated pain hypersensitivity induced by michigan cancer foundation-7 injection in rats with bone metastases from breast cancer by inhibiting transient receptor potential ankyrin 1.

OBJECTIVE: To study the effect and underlying mechanisms of Chinese medicine Yanghe decoction on pain relief in a rat model of bone metastasis of breast cancer induced by michigan cancer foundation-7 (MCF-7). METHODS: Bone pain was induced in the tibia of rats injected with MCF-7 cells. The Chinese herbal remedy was used to decoct Yanghe decoction for the treatment of bone pain rats. The behavior study was carried out to evaluate the paw mechanical withdraw threshold and thermal withdraw latency. Liquid chromatography-mass spectrometry, Western blotting, quantitative real-time polymerase chain reaction, enzyme-linked immunosorbent assay (ELISA), immunohistochemical (IHC) staining were performed for analysis. RESULTS: Yanghe decoction could improve the defensive behavior similar to the transient receptor potential ankyrin 1 (TRPA1) inhibitor. In morphology study, Yanghe decoction could attenuate the cellular growth as well as inflammatory infiltration in the metastasis group. Furthermore, Yanghe decoction downregulated the TRPA1 expression on the dorsal root ganglion from the metastatic rats at both transcriptional and protein level. Yanghe decoction alleviated the inflammation in metastatic tissues by hematoxylin-eosin and IHC analysis, and Yanghe decoction also reduced the inflammatory cytokines production in the serum including tumor necrosis factor-α and interleukin-6, interleukin-1 beta by ELISA. As the cytochromec oxidase subunit II/prostaglandin E2 (PGE2) is required for cancer development, Yanghe decoction reduced the expression of PGE2 in the tissue and serum. CONCLUSION: Taken together, Yanghe decoction protected the rats from breast cancer bone metastasis through TRPA1 signaling mediated neuropathic pain and additional immune modulation in tumor microenvironment.

A new method for studying the mechanism of "Feature Identification based quality assessment" of Traditional Chinese Medicine, taking Gastrodiae Rhizoma as an example.

Aim of the study: The research group proposed that the mechanism of "Feature Identification based Quality Assessment" (FIQA) of Traditional Chinese Medicine (TCM) can be explained according to the relationship between the "Feature" of TCM and the Pharmacodynamic Components representing the holistic effect of TCM. Gastrodiae Rhizoma (GR) was selected as the research object to reveal the close relationship between "Feature" and the quality of TCM. Materials and methods: In this study, the "Feature" such as "Shape", "Color", "Odour" and "Taste" of GR are quantified by the electronic nose, electronic tongue, and other instruments. Then, the Pharmacodynamic Components Group (PCG) of GR was determined which could reflect the holistic effect of GR by spectrum effect relationship analysis. By analyzing the correlation between the "Feature" and the content of PCG, the mechanism of FIQA of GR was determined. Results: The quantitative results of "Shape", "Color", "Odour" and "Taste" of GR from different sources were significantly different. Six components were selected as the PCG, which can represent the holistic effect of GR in the aspect of the neuroprotective effect. There was a good correlation between the components in the PCG and "Feature". Conclusions: The quality of GR can be determined quantitatively according to its "Shape", "Color", "Odour" and "Taste". The mechanism of FIQA of TCM can be explained according to the relationship between the Shape of TCM and the Pharmacodynamic Components representing the quality of TCM. The revelation of this mechanism reflects the holistic characteristics of the multi-component synergistic effect of TCM. This study provides a reference research method for revealing the mechanism of FIQA of TCM.

Butyrolactone I attenuates inflammation in murine NASH by inhibiting the NF-κB signaling pathway.

Nonalcoholic steatohepatitis (NASH) is the development of non-alcoholic fatty liver disease (NAFLD) and a key element in the exacerbation of NAFLD. Since there are currently no drugs approved by the U.S. Food and Drug Administration to treat this disease, the search for treatments that can be translated into clinical use is urgent. Butyrolactone I (BLI), isolated from Aspergillus terreus, is an active compound possessing multiple biological activities. However, the effects of BLI on NASH have never been reported. In this study, RAW264.7 cells stimulated by lipopolysaccharide (LPS) were applied to study the anti-inflammatory effect and the underlying mechanisms of BLI in vitro. Following this, mice fed with high-fat and -fructose diet (HFFD) were used to explore the alleviation of NASH by BLIin vivo. We found that BLI attenuated inflammation in LPS-induced RAW264.7 cells by inhibiting the NF-κB signaling pathway and downregulating the expression of iNOS and COX-2. Moreover, results of experiments in vivo demonstrated that BLI reduced serum transaminase levels, decreased hepatic fat accumulation, inhibited inflammation, suppressed oxidative stress, and ameliorated liver fibrosis. For the first time, we investigated the role of BLI in the treatment of murine NASH. We found that BLI alleviates NASH partly by inhibiting the NF-κB pathway of signaling. Given its hepatoprotective effects and non-toxic properties, BLI can be a novel and effective drug for NASH patients.
