BACKGROUND AND AIMS: The resect-and-discard strategy for colorectal polyps based on accurate optical diagnosis remains challenges. Our aim was to investigate the feasibility of hyperspectral imaging (HSI) for identifying colorectal polyp properties and diagnosis of colorectal cancer in fresh tissues during colonoscopy.
METHODS: 144,900 two dimensional images generated from 161 hyperspectral images of colorectal polyp tissues were prospectively obtained from patients undergoing colonoscopy. A residual neural network model was trained with transfer learning to automatically differentiate colorectal polyps, validated by histopathologic diagnosis. The diagnostic performances of the HSI-AI model and endoscopists were calculated respectively, and the auxiliary efficiency of the model was evaluated after a 2-week interval.
RESULTS: Quantitative HSI revealed histological differences in colorectal polyps. The HSI-AI model showed considerable efficacy in differentiating nonneoplastic polyps, non-advanced adenomas, and advanced neoplasia in vitro, with sensitivities of 96.0%, 94.0%, and 99.0% and specificities of 99.0%, 99.0%, and 96.5%, respectively. With the assistance of the model, the median negative predictive value of neoplastic polyps increased from 50.0% to 88.2% (p = 0.013) in novices.
CONCLUSION: This study demonstrated the feasibility of using HSI as a diagnostic tool to differentiate neoplastic colorectal polyps in vitro and the potential of AI-assisted diagnosis synchronized with colonoscopy. The tool may improve the diagnostic performance of novices and facilitate the application of resect-and-discard strategy to decrease the cost.
BACKGROUND: Tumor modeling using organoids holds potential in studies of cancer development, enlightening both the intracellular and extracellular molecular mechanisms behind different cancer types, biobanking, and drug screening. Intestinal organoids can be generated in vitro using a unique type of adult stem cells which are found at the base of crypts and are characterized by their high Lgr5 expression levels.
METHODS AND RESULTS: In this study, we successfully established intestinal cancer organoid models by using both the BALB/c derived and mouse embryonic stem cells (mESCs)-derived intestinal organoids. In both cases, carcinogenesis-like model was developed by using azoxymethane (AOM) treatment. Carcinogenesis-like model was verified by H&E staining, immunostaining, relative mRNA expression analysis, and LC/MS analysis. The morphologic analysis demonstrated that the number of generated organoids, the number of crypts, and the intensity of the organoids were significantly augmented in AOM-treated intestinal organoids compared to non-AOM-treated ones. Relative mRNA expression data revealed that there was a significant increase in both Wnt signaling pathway-related genes and pluripotency transcription factors in the AOM-induced intestinal organoids.
CONCLUSION: We successfully developed simple carcinogenesis-like models using mESC-based and Lgr5 + stem cell-based intestinal organoids. Intestinal organoid based carcinogenesi models might be used for personalized cancer therapy in the future.

BACKGROUND: Hepatic ischemia-reperfusion injury (HIRI) is commonly observed in cases of extensive hepatic resection and involves complex mechanisms. Cell senescence has been recognized as a factor in liver injury including HIRI, where it presents as a pro-inflammatory phenotype called senescence-associated secretory phenotype (SASP). Radix Rehmanniae Praeparata (RRP) is a commonly utilized traditional Chinese medicine known for its hepatoprotective, anti-aging and antioxidant qualities. Despite its recognized benefits, the specific mechanisms by which RRP may impede the progression of HIRI through the regulation of cell senescence and the identification of the most potent anti-aging extracts from RRP remain unclear.
MATERIALS AND METHODS: Here, we first applied different chemical analysis methods to identify the RRP aqueous extract (RRPAE) and active fractions of RRP. Next, we constructed a surgically established mouse model and a hypoxia-reoxygenation (HR)-stimulated liver sinusoidal endothelial cells (LSECs) model to explore the underlying mechanism of RRP against HIRI through transcriptomics and multiple molecular biology experiments.
RESULTS: After identifying active ingredients in RRP, we observed that RRP and its factions effectively restored LSECs fenestration and improved inflammation, cellular swelling and vascular continuity in the hepatic sinusoidal region during HIRI. Transcriptomic results revealed that RRP might reverse HIRI-induced senescence through the NOTCH signaling pathway and cell categorization further showed that the senescent cell population in HIRI liver was primarily LSECs rather than other cell types. Different RRPAE, especially RRP glucoside (RRPGLY), improved LSECs senescence and suppressed the expression of pro-inflammatory SASP genes either induced by HR insult or NOTCH1 activator, which was accompanied with the inhibition of LRP1-NOTCH1-C/EBPβ pathways. Additionally, the specific inhibition of NOTCH1 by siRNA synergistically enhanced the hepatoprotective effect of RRPGLY. The ChIP-qPCR results further showed that C/EBPβ was enriched at the promoter of a representative SASP, Il-1β, in hypoxic LSECs but was significantly inhibited by RRPGLY.
CONCLUSION: Our study not only clarified the potential mechanism of RRP active extractions in alleviating HIRI, but also highlighted RRPGLY was the main component of RRP that exerted anti-aging and anti-HIRI effects, providing a fresh perspective on the use of RRP to improve HIRI.
The present invention discloses a tetrandrine solid lipid nano-particle and a preparation method thereof. Tetrandrine extracted from traditional Chinese medicine, namely stephania tetrandra, is used as a medicine effective constituent, lipid materials, such as stearic acid, etc., are used as carriers, and soybean phospholipid, etc. are used as emulsifiers. An ultrasonic method and a high-pressure uniform emulsification method are adopted, the tetrandrine is coated and carried in a solid lipid nano-particle, and then the tetrandrine solid lipid nano-particle is prepared. The tetrandrine solid lipid nano-particle prepared by the present invention has the characteristics of small particle diameter, high stability and high envelopment ratio. The present invention not only can enhance bioavailability, but also can change the intracorporal process of the medicine, enhance the targeting character to the liver and the spleen, reduce the dosage and the toxic side effect of the medicine, and improve curative effect.
Adipose tissue stores triacylglycerol (TAG) in lipid droplets (LD) and release fatty acids upon lipolysis during energy shortage. We identify ApoL6 as a LD-associated protein mainly found in adipose tissue, specifically in adipocytes. ApoL6 expression is low during fasting but induced upon feeding. ApoL6 knockdown results in smaller LD with lower TAG content in adipocytes, while ApoL6 overexpression causes larger LD with higher TAG content. We show that the ApoL6 affects adipocytes through inhibition of lipolysis. While ApoL6, Perilipin 1 (Plin1), and HSL can form a complex on LD, C-terminal ApoL6 directly interacts with N-terminal Plin1 to prevent Plin1 binding to HSL, to inhibit lipolysis. Thus, ApoL6 ablation decreases white adipose tissue mass, protecting mice from diet-induced obesity, while ApoL6 overexpression in adipose brings obesity and insulin resistance, making ApoL6 a potential future target against obesity and diabetes.
The study was designed four arms. The investigators will perform colposcopy because of various causes. The first arm is used tenaculum and performed intracervical blockage. The second arm is not used tenaculum and performed intracervical blockage. The third arm is used tenaculum and not performed intracervical blockage. The fourth arm is not used tenaculum and not performed intracervical blockage and then we will study patients pain and biopsy size during colposcopic biopsy. Pain reduce and biopsy size are very important for patient and diagnose of the cervix cancer.
NEW MATERIAL:A compound which is obtained by esterifying maltopentaose with linoleic acid or alpha-linolenic acid in the 1-position. EXAMPLE:Maltopentaose 1-0-linolenate. USE:A component is intravenous nutrient transfusion containing saccharides and essential fatty acids. Since linoleic or alpha-linolenic acid, a hydrophobic and essential fatty acid, is converted into a water-soluble derivative, the fatty acid can be included in the transfusion solution containing saccharides in no need of emulsification. Thus, a homogeneous transfusion solution with high qualityl, safety and rich nutirents is obtained. PREPARATION:The condensation reaction between a reactive derivative of linoleic acid or alpha-linolenic acid such as thiazolidinethione-linoleic acid amide and maltopentaose is effected in a solvent such as pyridine in the presence of sodium hydride.

BACKGROUND: Tooth loss significantly impacts oral function and overall health deterioration. Dental caries and periodontal disease are major contributors to tooth loss, emphasizing the critical need to prevent these conditions. Genetic studies have played a crucial role in deepening our understanding of the underlying mechanisms of these diseases. While large-scale genome-wide association studies (GWAS) on dental caries and periodontal disease have been conducted extensively, research focusing on Asian populations remains limited. Given substantial genetic and lifestyle variations across ethnicities, conducting studies across diverse populations is imperative. This study aimed to uncover new insights into the genetic mechanisms of these diseases, contributing to broader knowledge and potential targeted interventions.
METHODS: We conducted a GWAS using genome data from 45,525 Japanese individuals, assessing their self-reported history of dental caries and periodontal disease. Additionally, we performed a meta-analysis by integrating our results with those from a previous large-scale GWAS predominantly involving European populations.
RESULTS: While no new loci associated with periodontal disease were identified, we discovered two novel loci associated with dental caries. The lead variants of these loci were intron variant rs10974056 in GLIS3 and intron variant rs4801882 in SIGLEC5.
CONCLUSION: Our study findings are anticipated to advance understanding of the underlying mechanisms of dental caries and periodontal disease. Thes insights may inform better management strategies for patients affected by these conditions.

The use of insoluble enzyme preparations comprising an enzyme which is immobilized on a solid carrier having an average particle size of from about 0.1 to 500 µm as additives in consumer near applications is disclosed. These insoluble enzyme preparations provide compositions with reduced safety risks regarding allergenicity compared to the free enzyme. Therefore, the insoluble enzyme preparations are beneficial when used in certain applications that involve direct contact of enzymes with humans either by handling, utilizing, or uptake of enzymes or enzyme containing compositions. Furthermore, the insoluble enzyme preparations have low dusting, high blendability and good dispersion characteristics which are particularly beneficial to numerous industries (including, but not limited to, personal care, oral care, home care, food and/or feed industries). The invention further relates to the use of insoluble enzyme preparations dispersed in single-use compositions which may be e.g. chewing gum, toothpaste, ointment, shampoo, deodorant, a silicone elastomer, dry provender for animal nutrition, a bakery composition like dough, paint or a home care composition like hard surface cleaner.
Statin is crucial for acute myocardial infarction (AMI) patients. However, the risk of new-onset diabetes mellitus (NODM) associated with statin is a concern. This study aimed to determine the incremental diabetogenic effects of statins according to their intensity and dose in AMI patients undergoing percutaneous coronary intervention (PCI). Among 13,104 patients enrolled in the Korea AMI Registry between 2011 and 2015, 6152 patients without diabetes mellitus (DM) who underwent PCI and received moderate-to-high-intensity atorvastatin and rosuvastatin were selected for the study. The endpoints were NODM and major adverse cardiovascular events (MACE), composite of all-cause mortality, recurrent MI, and revascularization up to 3 years. Among the participants, 3747 and 2405 received moderate- and high-intensity statins, respectively. The Kaplan-Meier curves demonstrated a higher incidence of NODM in patients with high-intensity statins than those with moderate-intensity. High-intensity statin was a significant predictor of NODM after adjusting for other co-variables (HR = 1.316, 95% CI 1.024-1.692; P < 0.032). Higher dose of rosuvastatin was associated with a higher cumulative incidence of NODM, but this dose-dependency was not apparent with atorvastatin. Cumulative incidence of MACE decreased dose-dependently only with atorvastatin. High-intensity statin was associated with a higher cumulative incidence of NODM in AMI patients, and this association was more evident in rosuvastatin. The different diabetogenic effects of the two statins provide supporting evidence for understanding the nuanced nature of statin treatment in relation to NODM.
PURPOSE: This study aimed to explore the incidence and severity of vincristine-induced peripheral neuropathy (VIPN) in non-Hodgkin lymphoma (NHL) survivors (primary aim) and its impact on daily life by comparing common cancer symptoms, functional status, and quality of life (QoL) among survivors with acute, long-term, and non-VIPN (secondary aim).
METHODS: This cross-sectional study examined 144 NHL survivors. Standardized questionnaires were used to assess common cancer symptoms, functional status, and QoL with the European Organization for the Research and Treatment of Cancer - Quality of Life Questionnaire (EORTC-QLQ-C30). VIPN (Chemotherapy-Induced Peripheral Neuropathy) status was classified using EORTC-QLQ-CIPN20. A self-designed interference scale was developed to determine the impact of the VIPN on daily activities. The Kruskal-Wallis test and Spearman rank correlation were used in this study.
RESULTS: Among the survivors of acute and long-term VIPN, the highest incidences and most severe symptoms were found for hand numbness and foot cramps. A significant moderate correlation was found between disturbances in daily activities and acute or long-term VIPN, including gait changes, going up or down the stairs, and imbalance-related falls. Acute and long-term VIPN survivors showed worse symptoms (fatigue, insomnia, and constipation) and lower QoL than non-VIPN survivors did. In acute VIPN, social function was significantly affected, whereas in long-term VIPN, emotional and cognitive functions were affected.
CONCLUSION: Numbness and cramps should be addressed in survivors of acute and long-term VIPN. Preventing falls is recommended for NHL survivors with VIPN, and psychological support is suggested for long-term VIPN survivors.
This retrospective, cross-sectional, and descriptive study aimed to analyze the trend of utilizing traditional Korean medicine services in patients with lumbar disc herniation (LDH) and/or lumbar spinal stenosis (LSS). In this study, based on the national patient sample data provided by Health Insurance Review and Assessment Service (HIRA), the trend of Korean medicine service utilization was investigated, including the following information: demographic characteristics of the patients, the total expenditure, number of claim statements per category, medical care expenditure per category, and routes of visiting traditional Korean medicine institutions. The study population comprised patients who visited Korean medicine institutions at least once from January 2010 to December 2019, with LSS and LDH as the primary diagnosis. LDH patients who used traditional Korean medicine services for treatment increased by about 1.36 times. LDH and LSS patients under 45 years of age were more likely to be males, but women accounted for a higher percentage among those over 45 years of age. Overall, women accounted for a slightly higher percentage than their counterparts for both diseases. From details of treatments received that were extracted from the claims data, acupuncture treatment accounted for the highest percentage for both disorders. Moreover, 50.7% of the patients who visited Korean medicine institutions to treat the two diseases also visited conventional Western medicine institutions. These patients, who were diagnosed with their condition at a Korean medicine institution, visited a conventional institution and then returned; the conventional institutions were primarily used for examination (40.5%). Increased utilization of traditional Korean medicine services was confirmed among patients with LDH and/or LSS; in particular, a sharp increase was noted among patients with LSS. The results of this study will be useful as basic research data for clinicians, researchers, and policy makers.
BACKGROUND: This study examined the effect of the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase 1 (HO-1) pathway on chronic obstructive pulmonary disease (COPD) and the potential molecular mechanism.
METHODS: A COPD mouse model was established by cigarette smoke exposure and administered with either ML385 or dimethyl fumarate (DMF). Airway resistance of mice was detected. IL-1β and IL-6 levels in mice alveolar lavage fluid were examined by enzyme-linked immunosorbent assay. Hematoxylin and eosin staining and immunohistochemical of lung tissues were utilized to detect lung injury and NLRP3 expression. DMF was used to treat COPD cell model constructed by exposing normal human bronchial epithelial (NHBE) cells to cigarette smoke extract. NHBE cells were transfected by NLRP3-expression vectors. Expression of proteins was detected by Western blot.
RESULTS: COPD mice showed the enhanced airway resistance, the inactivated Nrf2/HO-1 pathway and the overexpressed NLRP3, Caspase-1 and GSDMD-N proteins in lung tissues, and the increased IL-1β and IL-6 levels in alveolar lavage fluid. ML385 treatment augmented these indicators and lung injury in COPD mice. However, DMF intervention attenuated these indicators and lung injury in COPD mice. Nrf2/HO-1 pathway inactivation and overexpression of NLRP3, Caspase-1 and GSDMD-N proteins were observed in COPD cells. DMF intervention activated Nrf2/HO-1 pathway and down-regulated NLRP3, Caspase-1 and GSDMD-N proteins in COPD cells. However, NLRP3 overexpression abolished the effect of DMF on COPD cells.
CONCLUSION: Nrf2/HO-1 pathway activation may alleviate inflammation in COPD by suppressing the NLRP3-related pyroptosis. Activating the Nrf2/HO-1 pathway may be an effective method to treat COPD.
The neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein-to-prealbumin ratio (CPAR) are novel markers of inflammation. The CPAR is an indicator of inflammation and malnutrition. We evaluated NLR and CPAR in combination as indicators of disease severity and prognosis in hospitalized older patients with coronavirus disease 2019 (COVID-19). A total of 222 hospitalized patients with COVID-19 (aged > 60 years) were divided into non-severe and severe groups. The severe group was subdivided into the surviving and deceased subgroups. We retrospectively assessed the predictive power of NLR and CPAR in combination (NLR + CPAR) to determine the prognosis of hospitalized older patients with COVID-19. The NLR and CPAR were significantly higher in the severe group than in the non-severe group (P < .001). Furthermore, the NLR and CPAR were higher in the deceased subgroup than in the surviving subgroup (P < .001). Pearson correlation analysis showed a highly significant positive correlation between NLR and CPAR (P < .001, r = 0.530). NLR + CPAR showed an area under the curve of 0.827 and sensitivity of 83.9% in the severe group; the area under the curve was larger (0.925) and sensitivity was higher (87.1%) in the deceased subgroup. The receiver operating characteristic curve of NLR + CPAR was significantly different from the receiver operating characteristic curves of either biomarker alone (P < .001). Kaplan-Meier analysis showed that patients in the severe group with elevated NLR + CPAR had a significantly lower 90-day survival rate than patients who lacked this finding (odds ratio 7.87, P < .001). NLR + CPAR may enable early diagnosis and assessment of disease severity in hospitalized older patients with COVID-19. This may also enable the identification of high-risk older patients with COVID-19 at the time of admission.
