1. Out-of-Distribution Detection Using Peer-Class Generated by Large Language Model

Author: Huang, K, Song, G, Su, Hanwen, and Wang, Jiyan
Subjects: Computer Science - Computer Vision and Pattern Recognition
Abstract: Out-of-distribution (OOD) detection is a critical task to ensure the reliability and security of machine learning models deployed in real-world applications. Conventional methods for OOD detection that rely on single-modal information, often struggle to capture the rich variety of OOD instances. The primary difficulty in OOD detection arises when an input image has numerous similarities to a particular class in the in-distribution (ID) dataset, e.g., wolf to dog, causing the model to misclassify it. Nevertheless, it may be easy to distinguish these classes in the semantic domain. To this end, in this paper, a novel method called ODPC is proposed, in which specific prompts to generate OOD peer classes of ID semantics are designed by a large language model as an auxiliary modality to facilitate detection. Moreover, a contrastive loss based on OOD peer classes is devised to learn compact representations of ID classes and improve the clarity of boundaries between different classes. The extensive experiments on five benchmark datasets show that the method we propose can yield state-of-the-art results.

Moreover, serum liver enzymes (GGT, alanine aminotransferase [ALT], aspartate aminotransferase [AST], and alkaline phosphatase [ALP]) are associated with metabolic syndrome and its components, including hypertriglyceridemia. However, the relationship between liver enzymes and postprandial hypertriglyceridemia (PHTG) remains unclear. Therefore, in this study we conducted oral fat tolerance tests (OFTTs) to understand the differences in serum liver enzyme levels among individuals with different lipid tolerance levels and their correlation with PHTG.Patients and Methods: For the OFTT, we enrolled 202 non-diabetic volunteers whose fasting triglyceride (TG) levels were less than 1.7 mmol/L in this case-control study. The participants were categorized into two groups according to the TG levels at the 0- and 4-h OFTT: a postprandial normal TG (PNTG) group and a PHTG group. Routine fasting serum biochemical indices, liver enzyme (GGT, ALT, AST, and ALP) levels, and 0- and 4-h OFTT lipid levels were assessed.Results: The PHTG group had significantly higher serum GGT and ALT levels and a lower AST/ALT ratio than those in the PNTG group. However, no significant difference was observed in AST and ALP levels compared with the PNTG group. After adjusting for major confounders, logistic regression analysis indicated a significant correlation between serum GGT and PHTG (odds ratio = 1.168, P < 0.001), but not with ALT level, AST level, AST/ALT ratio, and ALP level. The receiver operating characteristic curve analysis demonstrated that the serum GGT level was an effective predictor of PHTG.Conclusion: Serum GGT levels are significantly associated with PHTG risk and serve as an effective biomarker for early identification.Keywords: gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, inflammation, triglyceride, oral fat tolerance test

One hundred and nineteen patients with T2DM were selected as the case group, and 123 people with non-T2DM were selected as the control group. People insulin resistance was detected by the homeostasis model assessment method (HOMA-IR) greater than 2.69 were included in the diabetic insulin resistance group, and those with HOMA-IR less than 2.69 were included in the diabetic non-insulin resistance group. Record the general body indicators, biochemical indicators, hepatic function indicators, vitamin E, and other indicators. Correlation analysis, logistic regression, trend analysis, and restricted cubic spline (RCS) were performed using SPSS 25.0 and R 4.1.1 software. Correlation analysis, logistic regression, trend analysis, restricted cubic spline (RCS) analysis were conducted on general body indicators, biochemical indicators, hepatic function indicators, vitamin E, and other indicators.Results: The logistic regression results showed that after adjusting for confounding factors, vitamin E was an independent influencing factor for insulin resistance in T2DM patients (P < 0.001). The trend analysis results show that with the decrease of serum vitamin E levels, the risk of insulin resistance in T2DM patients gradually increases. The RCS results showed that the risk of insulin resistance was significantly increased when the serum vitamin E level was lower than 10,575.23 ng/mL.Conclusion: Serum vitamin E levels are lower in T2DM patients than in healthy populations; Vitamin E is an independent influencing factor for HOMA-IR in T2DM patients. The risk of insulin resistance gradually increases in T2DM patients as serum vitamin E levels decrease. Vitamin E is a risk factor for insulin resistance at serum vitamin E levels below 10,575.23 ng/mL. At higher serum vitamin E levels than 10,575.23 ng/mL, vitamin E is a protective factor for insulin resistance.Keywords: Vitamin E, type 2 diabetes mellitus, insulin resistance, oxidative stress

Abstract: With the development of industry, drones are appearing in various field. In recent years, deep reinforcement learning has made impressive gains in games, and we are committed to applying deep reinforcement learning algorithms to the field of robotics, moving reinforcement learning algorithms from game scenarios to real-world application scenarios. We are inspired by the LunarLander of OpenAI Gym, we decided to make a bold attempt in the field of reinforcement learning to control drones. At present, there is still a lack of work applying reinforcement learning algorithms to robot control, the physical simulation platform related to robot control is only suitable for the verification of classical algorithms, and is not suitable for accessing reinforcement learning algorithms for the training. In this paper, we will face this problem, bridging the gap between physical simulation platforms and intelligent agent, connecting intelligent agents to a physical simulation platform, allowing agents to learn and complete drone flight tasks in a simulator that approximates the real world. We proposed a reinforcement learning framework based on Gazebo that is a kind of physical simulation platform (ROS-RL), and used three continuous action space reinforcement learning algorithms in the framework to dealing with the problem of autonomous landing of drones. Experiments show the effectiveness of the algorithm, the task of autonomous landing of drones based on reinforcement learning achieved full success.

Therefore, this study aimed to determine the level of PA in PD patients and investigate the associated psychological and behavioural factors.Methods: PD patients were recruited from the Department of Neurology of the First Hospital Affiliated with Dalian Medical University using convenience sampling for this cross-sectional study. A questionnaire covering social-demographic and disease-related characteristics, Chinese version of Impact on Participation and Autonomy (IPA) Questionnaire, Connor-Davidson Resilience Scale (CD-RISC), Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS), Medical Coping Modes Questionnaire (MCMQ), Social Support Rating Scale (SSRS), Hoehn-Yahr Staging System and Unified Parkinson’s Disease Rating Scale (UPDRS) were used for investigation. A multivariate stepwise linear regression analysis was used to determine the factors that influence IPA.Results: A total of 326 PD patients responded to all the questionnaires. The patients had a mean IPA score of 46.6 (SD 21.79). Multiple linear regression analyses revealed that UPDRS II (β = 0.35, p < 0.001) had the strongest correlation with IPA, followed by tenacity, which was the second strongest factor (β = − 0.25, p < 0.001). Hoehn-Yahr stage (β = 0.19, p < 0.001) and availability of social support (β =− 0.12, p =0.001) were also strong factors.Conclusion: The average level of PA among PD patients was at the lower middle-level. Among PD patients, physical function, psychological resilience and social support were the strongest factors associated with PA. These findings provide valuable insights into PD patients’ PA and can help medical professionals identify the early risks of restricted PA among PD patients, implement interventions to promote PA and ultimately achieve rehabilitation.Keywords: participation and autonomy, psychological resilience, social support, Parkinson’s disease, medical coping modes

Blood samples were obtained at 0, 2, and 4 h after eating to detect relevant indicators. PPT was defined as triglyceride (TG) levels ≥ 2.5 mmol/L. According to the test results, the participants were divided into two groups: postprandial normal triglycerides (PNT) and PPT. The levels of blood lipids and ANGPTL3, ANGPTL4, and ANGPTL8 were compared between the two groups.Results: There were differences in the body mass index (BMI), waist circumference (WC), fasting total cholesterol (TC), TG, low-density lipoprotein cholesterol (LDL-C), triglyceride-rich lipoprotein cholesterol (TRL-C), non-high-density lipoprotein cholesterol (non-HDL-C), apolipoprotein B (ApoB), ApoA1/ApoB, fasting blood glucose (FBG), fasting insulin (FINS), ANGPTL4, and ANGPTL8 between the two groups. In the PNT group, the TG level increased from baseline at 2 and 4 h, TRL-C increased from baseline at 4 h, and ANGPTL8 decreased from baseline at 2 and 4 h. After OFTT, the levels of TG, TRL-C, ANGPTL3, and ANGPTL4 in the PPT group gradually increased; ANGPTL8 gradually decreased. Fasting ANGPTL3 was positively associated with age, TC, HDL-C, TRL-C, and ApoA1, and negatively associated with systolic blood pressure. Fasting ANGPTL4 was positively correlated with weight, WC, BMI, TC, TG, LDL-C, TRL-C, non-HDL-C, ApoB, FBG, and FINS, and negatively correlated with ApoA1/ApoB and fasting ANGPTL8. Binary logistic regression analysis indicated that ANGPTL4 and ANGPTL8 were significant predictors of PPT.Conclusion: PPT occurrence is closely associated with changes in ANGPTL4 and ANGPTL8 levels.Keywords: dyslipidemia, serum lipid, ANGPTL proteins, oral fat tolerance test, postprandial normal triglyceride

Abstract: We propose the construction of LEGEND-1000, the ton-scale Large Enriched Germanium Experiment for Neutrinoless $\beta \beta$ Decay. This international experiment is designed to answer one of the highest priority questions in fundamental physics. It consists of 1000 kg of Ge detectors enriched to more than 90% in the $^{76}$Ge isotope operated in a liquid argon active shield at a deep underground laboratory. By combining the lowest background levels with the best energy resolution in the field, LEGEND-1000 will perform a quasi-background-free search and can make an unambiguous discovery of neutrinoless double-beta decay with just a handful of counts at the decay $Q$ value. The experiment is designed to probe this decay with a 99.7%-CL discovery sensitivity in the $^{76}$Ge half-life of $1.3\times10^{28}$ years, corresponding to an effective Majorana mass upper limit in the range of 9-21 meV, to cover the inverted-ordering neutrino mass scale with 10 yr of live time.

On the day of IVF-ET with donor sperm transplantation, patients were investigated with general data questionnaire, self-rating anxiety scale (SAS) and self-rating depression scale (SDS) to analyze their anxiety and depression scores and their influencing factors.Results: Scores of anxiety and depression on the day of transplantation in patients receiving IVF-ET with donor sperm were 43.98± 6.80 and 46.03± 10.61 respectively, which were higher compared to levels of Chinese health norm (P< 0.05). The anxiety score of patients’ spouses was 41.23± 6.69 and depression score was 44.23± 11.65, which were higher compared to levels of Chinese health norm (P< 0.05). Score of anxiety and depression of women was significantly higher compared to those of their spouse (P< 0.05). Anxiety and depression scores of women in non-pregnant group were significantly higher compared to those in pregnant group (P< 0.05). Regression analysis showed that education level and annual family income were influencing factors of anxiety and depression scores of IVF-ET with donor sperm couples on the day of transfer, and number of eggs taken and transfer times were influencing factors of depression scores of IVF-ET with donor sperm patients on the day of transfer.Conclusion: Psychological state of couples receiving IVF-ET with donor sperm was significantly affected, especially in female side. Medical staff should focus on patients with low education level, low family income, and more times of transfer and egg retrieval, and take targeted intervention measures to keep them in good psychological state, which is conducive to improving pregnancy outcome.Keywords: in vitro fertilization and embryo transfer with donor sperm, day of transfer, anxiety, depression, psychological state

To investigate this, we observed the changes in blood lipid levels after an oral fat tolerance test (OFTT) and examined the short-term effects on FGF21.Patients and Methods: A total of 158 non-diabetic adult volunteers who underwent OFTT were randomly recruited from the Hebei General Hospital. Participants were stratified into three groups according to fasting and 4-h postprandial triglyceride levels: normal fat tolerance (NFT), impaired fat tolerance (IFT), and hypertriglyceridemia (HTG). Blood samples were collected at 2-h intervals for 6 h. Circulating total cholesterol levels, triglycerides, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, free fatty acids (FFA), and FGF21 were assessed.Results: Fasting FGF21 levels increased progressively in the NFT, IFT, and HTG groups and were strongly correlated with FFA levels (r = 0.531, P < 0.001). During the OFTT, the FFA and FGF21 levels decreased and then increased after reaching a nadir at 2 and 4 h, respectively. After adjusting for potential risk factors, the FFA incremental area under the curve (iAUC) was an independent influencing factor of FGF21 iAUC (P = 0.005).Conclusion: Fasting FGF21 levels showed a strong positive correlation with FFA. During OFTT, changes in FGF21 levels were closely associated with alterations in FFA exogenously changed by OFTT. Moreover, they were linearly related to each other. Therefore, the serum FGF21 level is positively correlated to the FFA level in the postprandial period.Keywords: fibroblast growth factor 21, free fatty acid, lipids, dyslipidemia, postprandial state, oral fat tolerance test

Anthropometric parameters, islet function, biochemical parameters and body composition of T2DM group and control group were determined. Correlation analysis and logistic regression were used to evaluate the risk factors associated with the onset of insulin resistance in T2DM.Results: The folate levels in type 2 diabetic patients with insulin resistance were significantly lower than those in patients without insulin resistance. Logistic regression showed that FA and high-density lipoprotein were independent influencing factors for insulin resistance in diabetic patients (P < 0.05). After adjusting for confounding factors, the degree of insulin resistance in diabetic patients was in a significant inverse relationship with folate levels (P< 0.05). We also found that below the serum FA threshold of 7.09 ng/mL insulin resistance was significantly more elevated.Conclusion: Our findings suggest that the risk of insulin resistance increases with the decrease in serum FA levels in T2DM patients. Monitoring folate levels in these patients and FA supplementation are warranted preventive measures.Keywords: folic acid, type 2 diabetes mellitus, insulin resistance, Chinese

T2DM patients were sub-classified into groups based on whether they had diabetic peripheral neuropathy (DPN), diabetic retinopathy (DR), and diabetic kidney disease (DKD). Clinical data including demographic characteristics and blood test results [serum levels of osteocalcin (OC), N-terminal propeptide of type 1 procollagen (P1NP), and β-crosslaps (β-CTX)] were collected. Logistic regression and restrictive cubic spline curves were performed to examine the association of BTMs with the risk of T2DM and microvascular complications.Results: After adjusting for family history of diabetes, sex and age, an inverse association was observed between elevated serum OC levels [O, p < 0.001] and increased serum P1NP levels , p < 0.001] with the risk of T2DM. Moreover, there was an inverse linear association of serum OC and P1NP levels with the risk of T2DM. However, β-CTX was not associated with T2DM. Further analysis showed a nonlinear association between OC and the risk of DR, while P1NP and β-CTX were not correlated with DR. Serum concentrations of BTMs were not associated with the risks of DPN and DKD.Conclusion: Serum OC and P1NP levels were negatively correlated with T2DM risk. Particularly, serum OC levels were associated with DR risk. Given that BTMs are widely used as markers of bone remodeling, the present finding provides a new perspective for estimating the risk of diabetic microvascular complications.Keywords: bone turnover markers, type 2 diabetes mellitus, microvascular complications

Flow cytometry, fluorescence staining, Western blot, T-AOC, DPPH radical scavenging assay, hydroxyl radical’s inhibitory capability and GSH test were used to examine the esculetin’s effects on the ROS level, the oxidation-related substances and proteins’ expression in hepatoma cells. In vivo experiment was performed by xenograft model. Ferrostatin-1 was used to determine the death way of hepatoma cells induced by esculetin. Live cell probe, Western blot, Fe2+ content, MDA, HE staining, Prussian blue staining and immunohistochemistry were used to examine the ferritinophagy-related phenomenon induced by esculetin in hepatoma cells. The relationship between esculetin and NCOA4-mediated ferritinophagy was confirmed through gene silence and overexpression, immunofluorescence staining and Western blot.Results: Esculetin suppressed the proliferation, migration and apoptosis of HUH7 and HCCLM3 cells significantly, influenced the oxidative stress level, altered the autophagy and iron metabolism levels in cells, and produced a ferritinophagy-related phenomena. Esculetin increased the levels of cellular lipid peroxidation and reactive oxygen species. In vivo, esculetin could decrease tumour volume, promote LC3 and NCOA4 expressions, suppresse hydroxyl radical‘s inhibiting capacity and GSH, increase Fe2+ and MDA levels, decrease antioxidant proteins expression in tumour tissue. In addition, Esculetin could also increase the iron deposition of tumour tissues, promote ferritinophagy, and induce tumours’ ferroptosis.Conclusion: Esculetin has an inhibitory effect on liver cancer in vivo and in vitro through triggering NCOA4 pathway-mediation ferritinophagy.Keywords: esculetin, ferritinophagy, liver cancer, anti-tumour, NCOA4

Abstract: While the mitigating effects of trees on shallow landslide occurrence are well recognised, the impact of landslides on tree community structure and tree-tree interactions have received much less research attention. The structures of tree communities before and after landslides were compared in a 25-ha subtropical forest plot. Tree-tree interactions were examined by analysing the pre- and post-landslide spatial point patterns of large (DBH ≥ 20 cm) and small (1 cm ≤ DBH < 20 cm) tree cohorts. In landslide scarps, 35 (34%) of 104 large trees and 467 (13%) of 3.072 small trees survived. Large (L) and small (S) tree cohorts were paired together for spatial analyses, including pre-landslide (PL) (LPL-SPL), surviving (S) (LS-SS), and missing (M) large-small tree paired cohorts (LM-SM). We randomly selected trees from the pre-landslide tree cohorts to create two virtual paired cohorts, the L34%-S13% and L66%-S87% paired cohorts, whose population sizes were identical to the field-observed LS-SS and LM-SM paired cohorts respectively, but with random spatial patterns. Post-landslide survival rates of trees increased monotonically with DBH. Large trees dislodged by landslides scarcely reduced small-tree survival. Evidence for this included: (i) the distance from small trees to the nearest large trees of the LM-SM paired cohort did not differ significantly from that of the virtual L66%-S87% paired cohort; (ii) survival rates of small trees near LM individuals did not differ significantly from those without large trees nearby. Surviving large trees had positive effects on the survival of small trees, indicated by: (i) the distance from small trees to the nearest large trees of the LS-SS paired cohort was significantly lower than that of the virtual L34%-S13% paired cohort; (ii) SS individuals clumped around LS individuals, whereas the virtual L34%-S13% spatial relationship was random. Large trees prevent landslide dislodgement of adjacent small trees through the nurse-plant effect. Our study suggests that landslide damage in sloping forests may be reduced simply by constantly maintaining a critical density of large trees.

The basic information of occupational exposure, factors influencing different occupational exposure types, ways to discover occupational exposure, discovery places of occupational exposure, and specific occurrence scenarios were compiled and analyzed among these data.Results: Occupational exposure mainly occurred in nurses (37, 46.25%), and cleaning (21, 26.25%). After the occurrence of occupational exposure, 20 staff (25%) did not know the occurrence time. Moreover, occupational exposure types were listed from high to low proportion as follows: broken protective clothing (56, 70%), mask loosening or displacement (13, 16.25%), skin exposure (6, 7.5%), and sharp object injuries (5, 6.25%). Occupational exposure was discovered mainly through self-discovery (56, 70%), while other discovery ways were majorly colleague discovery (12, 15%) and infection control supervisor discovery (12, 15%). Furthermore, occupational exposure was discovered principally in the public area (53.75%) and the office area (25%) of the cabin, but the proportion of mask loosening or displacement (38.46%) and skin exposure (50%) was also high in the first unloading area. Broken protective clothing occurred in the following scenarios: scratching while working in the cabin (37, 66.07%) and not knowing its occurrence time (25%). The occurrence scenarios of mask loosening or displacement were mainly not knowing its occurrence time (6, 46.15%), self-discovery (3, 23.08%), and at the time of removal (3, 23.08%).Conclusion: Targeted training and prevention of occupational exposure should be performed to decrease infection risk and ensure staff safety in Fangcang shelter hospitals.Keywords: Fangcang shelter hospital, occupational exposure, characteristics, scenarios, SARS-CoV-2 Omicron

The aim of this study was to investigate the relationship between C1306T, 1612– 5A/6A, C-1562T polymorphisms of MMP-2,3,9 genes and IS in Chinese Han population.Methods: The polymorphisms of MMP-2(C1306T), − 3(1612– 5A/6A), − 9(C-1562T) gene were detected by PCR-RFLP and SNaPshot sequencing. Then, stratified analysis was used to study the relationship between IS subtypes and MMP-2,3,9 polymorphisms.Results: For the MMP-2 gene C1306T polymorphism, TT genotype and T allele were significantly associated with a reduced risk of IS (P = 0.015, P = 0.003, respectively). T allele was significantly associated with a reduced risk of small artery occlusion (SAO) subtype compared with the control group (P = 0.012, OR = 0.550, 95% CI = 0.065– 1.291). For the MMP-3 gene-1612 (5A/6A) polymorphism, 5A/5A genotype was significantly increased in the IS group (P = 0.011, OR = 0.370, 95% CI = 0.168– 0.814), especially in the large-artery atherosclerosis (LAA) subtype (P = 0.001, OR = 2.345) as compared to the control group.Conclusion: Our study suggested that the T allele of MMP-2 may be a protective factor of IS, especially in SAO subtype, while the 5A/5A gene of MMP-3 may increase the risk of IS, especially in LAA subtype in Chinese Han population.Keywords: ischemic stroke, matrix metalloproteinase, polymorphism, association study

Extrinsic and intrinsic subdivision is one of the most common types, defined in terms of total serum immune globulin E (IgE) and/or specific IgE to food and environmental allergens. Extrinsic AD is the most common type (80%), with high IgE, impaired skin barrier, as well as high incidence of comorbid atopic diseases, whereas intrinsic AD accounted for 20% of AD, with normal IgE and intact barrier function. Clinical studies have shown that extrinsic AD was a classic Th2-based inflammatory dermatitis, while the intrinsic subtype presented increased Th1/Th17/Th22 but normal Th2 cytokines. Protein sensitization, a classic Th2 response, has been clearly characterized in extrinsic AD, while metal hapten induces intrinsic AD’s sensitization, which may be associated with suprabasin deficiency. In this review, we aimed to further expand our knowledge about similarities and differences between these two subtypes, which will expand our capability to further dissect pathophysiology of AD and enable us to develop personalized medicine approaches.Keywords: intrinsic atopic dermatitis, extrinsic atopic dermatitis, epidermal barrier, immune dysfunction, immune globulin E

Family environment and school life play important roles in shaping adolescent mental health. Our study aimed to examine the effect of parent-adolescent communication, school-life experiences, learning difficulties, and confidence in the future on depressive symptoms. We also examined the mediating effects of school-life experiences, learning difficulties, and confidence in the future on the relationship between parent-adolescent communication and depressive symptoms.Methods: Data on depressive symptoms, parent-adolescent communication, and mediating variables were obtained from the China Education Panel Survey (CEPS), including baseline data (2013– 2014) and follow-up data (2014– 2015). Mixed-effect models were used to evaluate the effects of parent-adolescent communication, school-life experiences, learning difficulties, and confidence in the future on depressive symptoms, and path analyses were performed to determine the mediating roles of school-life experiences, learning difficulties, and confidence in the future on the relationship between parent-adolescent communication and adolescent depressive symptoms.Results: More father-adolescent communication, better school-life experiences, and higher confidence in the future were protective factors for depressive symptoms among all boys and girls, and learning difficulties were a risk factor for depressive symptoms among all boys and girls. School-life experiences, learning difficulties, and confidence in the future had statistically significant mediating effects on the relationship between parent-adolescent communication and depressive symptoms.Conclusion: More father-adolescent communication, higher confidence in the future, better school-life experiences, and fewer academic difficulties were associated with lower levels of depressive symptoms. Both mother-adolescent communication and father-adolescent communication affected depressive symptoms through their effects on school-life experience, learning difficulties, and confidence in the future. This finding highlighted the importance of parent-adolescent communication and its impact on depression.Keywords: depression, communication, adolescent, CEPS

KRBA1 is a member of the KRAB family and participates in the regulation of gene transcription. However, no studies have focused on the role of KRBA1 in HCC.Patients and Methods: In this study, we first analyzed the expression of KRBA1 in HCC using TCGA and ICGC databases and validated by Immunohistochemistry in clinical HCC samples. The Wilcoxon rank-sum test was used to determine the relationship between KRBA1 expression and clinicopathological features. Subsequently, we used Kaplan-Meier online website analysis and Cox regression model to predict the prognostic value of KRBA1 in HCC patients. Furthermore, the functions of KRBA1 were identified by enrichment analysis. TIMER and GSCALite were used to investigate the relationship between KRBA1 expression in HCC and immune infiltration and drug targets, respectively. Finally, the relationship between KRBA1 expression and m6A modification in HCC was analyzed using the TCGA and ICGA datasets.Results: The results showed that KRBA1 was upregulated in HCC and was associated with many clinicopathological features. High KRBA1 causes poor overall survival and may be an independent risk factor for HCC. KRBA1 tends to be hypermethylated and associated with poor prognosis in HCC compared with normal tissues. Enrichment analysis indicates that KRBA1 is associated with cell cycle and immune processes, and TIMER analysis shows that KRBA1 expression is associated with infiltration levels and immune characteristics of various immune cells. Silenced KRBA1 evidently reduced three chemokine expression in HCC cells. Drug sensitivity analysis showed that KRBA1 was sensitive to 39 drug small molecules. KRBA1 showed a strong positive correlation with five m6A related genes.Conclusion: KRBA1 is a prognostic biomarker associated with HCC immunity and m6a modification, serving as an effective target for the diagnosis and treatment of HCC.Keywords: KRBA1, prognosis, biomarker, immune infiltration, hepatocellular carcinoma, m6A modification

It is relatively difficult to have preoperative diagnosis due to the lack of specific tumor markers and pre-operative images.Methods: In the present study, database of the pancreas center in the First Affiliated Hospital of Nanjing Medical University was retrospectively screened. A total of thirteen cases diagnosed as undifferentiated carcinoma of pancreas with osteoclast-like giant cells were included. Their clinical data and treatments were collected.Results: Thirteen patients include eight males and five females, and the median age was 67 (60– 72) years old. The lesions were found in more than half patients through health examination with no symptoms. NSE was elevated in eight cases (66%). CT scan revealed that cystic and solid lesions often had thick (4/5), contrast-enhanced (5/5) wall with smooth edges (5/5) and the boundary of lesions mainly with solid composition (4/10) is not well demarcated with normal pancreatic parenchyma. All patients received surgical resection. Eight patients had adjuvant chemotherapy and only one patient had adjuvant radiotherapy. The median survival time was 13 months. Five patients had postoperative metastasis or recurrence of tumor and four of them had died of this disease during follow-up.Conclusion: Our data showed that elevated level of NSE and characteristic pre-operative images might provide aid with the pre-operative diagnosis for undifferentiated carcinoma of pancreas with osteoclast-like giant cells. Patients with suspected diagnosis should receive surgical intervention as soon as possible, supplemented with postoperative chemotherapy, in order to prolong the survival of patients.Keywords: pancreatic cancer, undifferentiated carcinoma of pancreas, osteoclast-like giant cells, retrospective, pre-operative image

Male pups were randomly selected from LBW and normal-birth weight (NBW) offspring, then all given a high-fat diet. Blood glucose, serum insulin, total cholesterol (TC) and triglyceride (TG) levels were measured. The weight ratio of liver, muscle, and adiposity index were calculated. Hematoxylin and eosin staining was used to visualize adipose tissue morphology. Oil red O staining of liver and TG content of muscle were used to determine ectopic lipid deposition. TMT combined with LC-MS/MS was used to analyze protein expression in white adipose tissue. PRM and Western blot were used to verify the expression of CD36, SCD1, PCK1 and PPARγ.Results: Compared with NBW mice, fasting blood glucose, insulin and HOMA-IR significantly increased in LBW mice, indicating insulin resistance and impaired glucose regulation; TC, TG, adipocyte size, and adiposity index were increased in LBW mice, suggesting obesity and disorder of lipid metabolism. We observed ectopic lipid deposition in liver and muscle. There were 996 differentially expressed proteins (DEPs) in the LBW/NBW groups. Peroxisome proliferator-activated receptor (PPAR) was a relatively important signaling pathway regulating metabolic process in functional enrichment analysis of DEPs. Up-regulated expression of CD36, SCD1, and PCK1 in the adipose tissue of LBW mice was observed through PPAR pathways cluster analysis. And PRM and Western blot assay validated the proteomics findings.Conclusion: When exposed to high-fat diets, LBW mice exhibited insulin resistance and disorder of lipid metabolism compared with NBW mice. The expression of PPARγ was elevated, as well as upstream CD36, downstream SCD1 and PCK1 of the PPARγ in the adipose tissue of LBW mice. It was suggested that the activation in CD36/PPARγ/SCD1 and CD36/PPARγ/PCK1 pathways may induce adipose dysfunction, thereby increasing susceptibility to insulin resistance.Keywords: low birth weight, adipose tissue, insulin resistance, lipid metabolism

According to abdominal ultrasound findings, patients were divided into two groups: MAFLD group and non-MAFLD group. A total of 734 patients were diagnosed with MAFLD. Participants were divided into three study groups according to the SUA/Cr ratio. Chi-square test and one-way analysis of variance were used to perform a comparison between groups. The relationship between SUA/Cr ratio and MAFLD risk was analyzed using correlation analysis and regression analysis. Furthermore, subgroup analyses were performed to verify the robustness of the results.Results: The detection rate of MAFLD in patients with T2DM was 51.2%, and the detection rate of progressive liver fibrosis in T2DM patients with MAFLD was 36.6%. A significantly higher SUA/Cr ratio was seen in the MAFLD group than in the non-MAFLD group. After adjusting for confounding factors, multivariate logistic regression analysis revealed that the SUA/Cr ratio was an independent risk factor for MAFLD development. Stronger correlations were found in participants with a body mass index ranging between 23 and 28 kg/m2, HbA1C > 7%, or female sex.Conclusion: An elevated SUA/Cr index is independently correlated with an increased risk of MAFLD in Chinese adults with T2DM.Keywords: metabolic-associated fatty liver disease, type 2 diabetes, SUA/Cr

Local anesthetic techniques, a universal component of perioperative multimodal analgesia, are reportedly effective in reducing pain scores and opioid requirements. However, the optimal local anesthetic technique for postoperative CS pain remains unclear.Methods: Six databases were searched, and a Bayesian network meta-analysis was performed. The outcomes included cumulative morphine consumption and pain scores at four time points, time to first analgesic request, postoperative nausea and vomiting, pruritus, and sedation.Results: Sixty-eight studies with 5039 pregnant women were included. Six local anesthetic techniques were involved, including transversus abdominis plane block (TAPB), ilioinguinal and iliohypogastric nerve block, quadratus lumborum blocks, transversalis fascia plane block, erector spinae block, and wound infiltration. Compared to inactive controls, TAPB reduced cumulative morphine consumption at 6, 12, 24, and 48 h, pain scores at 6, 12, and 24 h (with the exception of 24 h at rest), the risk of postoperative nausea and vomiting, and sedation. Compared with inactive controls, ilioinguinal and iliohypogastric nerve block reduced cumulative morphine consumption at 6 and 24 h and pain scores at 6, 12, and 24 h during movement. Compared with inactive controls, quadratus lumborum blocks reduced cumulative morphine consumption at 24 and 48 h and pain scores at 6 and 12 h and lengthened the time to first analgesic request. Compared with inactive controls, wound infiltration reduced cumulative morphine consumption at 12 and 24 h, pain scores at 12 and 24 h during movement, and risk of sedation. Compared with inactive controls, erector spinae block reduced pain scores at 6 and 12 h. Transversalis fascia plane block was found to have similar outcomes to inactive controls.Conclusion: TAPB is the most comprehensive local anesthetic technique for postoperative CS analgesia in the absence of intrathecal morphine.Keywords: Cesarean section, postoperative pain, network meta-analysis, local anesthesia

The development of obesity is a dynamic process that can be described as a multistate process with an emphasis on transitions between weight states. However, it is still unclear what convenient biomarkers predict transitions between weight states. The aim of this study was to show the dynamic nature of weight status in adults stratified by age and sex and to explore blood markers of metabolic syndrome (MetS) that predict transitions between weight states.Methods: This study involved 9795 individuals aged 18 to 56 at study entry who underwent at least two health check-ups in the eight-year period of study in the health check-up centre of our institution. Weight, height and biochemical indices were measured at each check-up. The participants were divided into four groups based on age and sex (young male, middle-aged male, young female and middle-aged female groups). A multistate Markov model containing 3 states (healthy weight, overweight and obesity) was adopted to study the longitudinal weight data.Results: Young people were more likely to transit between weight states than middle-aged people, and middle-aged people were more resistant to recover from worse states. The mean sojourn time in obesity was greatest in the middle-aged male group (6.23 years), and the predicted rate of obesity beginning with healthy weight was greatest in the young male group (13.7%). In multivariate models, age group and triglyceride (TG) and high-density lipoprotein cholesterol (HDL) levels were significant for specific transitions in females, whereas age group and HDL levels were significant in males. In females, if HDL levels increased 1 mmol/L, the probability of progression from healthy weight to overweight decreased by 37.0% (HR= 0.63), and the probabilities of recovery (overweight to healthy weight and obesity to overweight) increased by 62.0% (HR= 1.62) and 1.23-fold (HR= 2.23), respectively. In males, if TG levels increased 1 mmol/L, the risk of progression from healthy weight to overweight increased by 24.0% (HR= 1.24). Each unit increase in HDL levels was associated with a 0.99-fold (HR= 1.99) increase in the chance of recovery from overweight to healthy weight and with a 0.37-fold (HR= 0.63) decrease in the risk of progression from healthy weight to overweight.Conclusion: The weight status of young people was less stable than that of middle-aged people. Males were more likely to become overweight and more resistant to recover from worse states than females. Young males with healthy weight were more likely to develop obesity than other healthy weight groups. Blood lipid levels, especially HDL, were predictors of weight transitions in adults. Prevention and intervention measures should be applied early.Keywords: obesity, multistate Markov model, triglyceride, high-density lipoprotein cholesterol, low density lipoprotein cholesterol

The 0.5 McFarland (Mc) concentration of the bacterial suspension was inoculated in cation-adjusted Mueller-Hinton broth (CAMHB) with a final cell turbidity of 5× 105 CFU/mL. The broth was incubated with serial concentrations of antibiotics. After centrifuging the bacterial suspensions, the lysed cells were analyzed by MALDI-TOF MS to identify the growth-promoting or inhibitory effects on K. pneumoniae. The molecular mechanisms of resistance were investigated by PCR and DNA sequencing analysis.Results: The expression of known resistance genes (blaKPC, blaFOX, blaDHA, blaCTX-M and blaTEM) was detected in the 30 carbapenems-resistant strains. The agreement between the MIC values derived from the MALDI-TOF MS analysis and from the broth micro-dilution method was 61.7% for ceftriaxone and 71.7% for imipenem. According to the Clinical and Laboratory Standards Institute (CLSI) breakpoint of resistance to ceftriaxone and imipenem, the 60 isolates were accurately classified as resistant or susceptible isolates with 100% sensitivity and 100% specificity.Conclusion: The transmission and infection of multidrug-resistant bacteria could be better managed and treated with the rapid identification of strains and antimicrobial susceptibility. A MALDI-TOF MS-based susceptibility test could be used to identify resistance of K. pneumoniae within a short time-frame. This approach could potentially be used as a supplementary antimicrobial susceptibility test that could be investigated on more bacterial species combined with different antibiotics.Keywords: Klebsiella pneumoniae, matrix-assisted laser desorption ionization–time of flight mass spectrometry, carbapenemases, extended-spectrum β-lactamases, antimicrobial susceptibility test

Participants with T2DM were recruited from the Department of Endocrinology in Hebei General Hospital according to inclusion and exclusion criteria. Data on basic characteristics and blood parameters were collected. We used the IR index (20/[fasting C-peptide × fasting plasma glucose]) to evaluate IR. Potential confounding factors were selected from comparisons among different IR index groups of quartiles and were adjusted in different models.Results: We included 172 subjects (121 men and 51 women) whose mean age was 53.2± 10.6 years. Body mass index (BMI), DM course, insulin use, glycated hemoglobin (HbA1c), fasting blood glucose, fasting C-peptide, triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (ApoA1), and albumin were differed among different IR-index groups (all P value < 0.05). In models 1 and 2, no or some confounding factors were adjusted for, and we found that there was no relationship between 25OHD and the IR index. In model 3, when all confounding factors (DM course, insulin use, BMI, HbA1c, TG, HDL-C, ApoA1, albumin and other bone turnover markers) were adjusted for, the IR index was increased by 5.6% when 25OHD levels increased by 1 ng/mL (odds ratio: 1.056; 95% confidence interval: 1.009, 1.105).Conclusion: Vitamin D is independently associated with IR in patients with T2DM.Keywords: diabetes mellitus, type 2, vitamin D, insulin resistance

Long non-coding RNA (lncRNA) is a significant factor in the development of PC. In the current study, the possible effects of HOTAIR on the epithelial–mesenchymal transition (EMT) of PC and the related mechanisms were investigated.Methods: The PC models were induced by 10 mg/100 g dimethylbenzoanthracene (DMBA) in pancreas. Mice were injected with the HOTAIR mimic and HOTAIR shRNA to determine the role of HOTAIR in PC. Subsequently, the expression of HOTAIR in PC cells was assayed. To determine the mechanism of HOTAIR in PC, human PC cell line PANC-1, Miapaca-2 and human normal pancreatic ductal epithelial cell line HPDE6-C7 were transfected with the HOTAIR mimic, the shRNA against HOTAIR, the Wnt/b-catenin activator (LiCl), and the Wnt/b-catenin inhibitor (XAV939), respectively. Moreover, the expressions of the Wnt/β-catenin signaling pathway-related genes (β-catenin, cyclinD1, c-myc, LEF-1 and c-Jun) and the levels of the EMT markers (E-cadherin, N-cadherin and Vimentin) were determined. Finally, the cell biological processes were evaluated by functional experiments.Results: HOTAIR was found to be highly expressed in the PC cells in mice. The expression of β-catenin, cyclinD1, c-myc, LEF-1 and c-Jun, N-cadherin and Vimentin was found to be decreased, while the expression of E-cadherin was found to be increased subsequent to the silencing of HOTAIR in human PC cell lines PANC-1 and Miapaca-2. Additionally, it was observed that the silencing of HOTAIR could inhibit the Wnt/β-catenin signaling pathway to alleviate EMT of tumor cells and inhibit the capacities of cell proliferation, migration, and invasion.Conclusion: The key finding of the present study is that the silencing of HOTAIR could potentially inhibit EMT and growth of PC through the Wnt/β-catenin signaling pathway, providing a novel therapy for PC.Keywords: long non-coding RNA, HOTAIR, Wnt/β-catenin signaling pathway, epithelial–mesenchymal transition, pancreatic cancer
