In this study, we provide valuable insights in the field by examining the evolution of the relationship between COPD and CHD over the past 20 years.Methods: A comprehensive computer search was conducted in the Web of Science (WOS) core dataset, covering literature on COPD combined with CHD from January 1, 2005, to August 20, 2024. Visual analyses were performed using VOSviewer, CiteSpace, and Bibliometrix to assess countries, institutions, the centrality of institutional intermediaries, authorship patterns, including co-cited authors and references, and keywords; Excel (version 2021) software was utilized for generating relevant descriptive analysis tables.Results: A total of 2420 publications sourced from WOS were included in this study. Since 2005, there has been a continuous increase in the literature about COPD combined with CHD; polynomial fitting yielded an R² value of 0.7758. The volume of literature in this domain is projected to continue growing steadily. The United States emerged as the leading country by publication count; Lin Cheng-li ranked first among authors, while China Medical University topped institutional contributions. Notably, Sin dd, Mannino dm, and Helvaci Mr were identified as the top three authors based on citation frequency. The Journal of Vascular Surgery recorded the highest number of publications, whereas The Lancet was recognized as the most influential among the top ten co-cited journals. The most frequently cited reference pertains to systemic inflammation’s role in increasing cardiovascular risk among patients with COPD. Through keyword clustering analysis, we categorized all keywords into three distinct groups: management strategies for COPD and CHD; diseases associated with both conditions; and epidemiological characteristics concerning their burden—current hotspots include multimorbidity factors such as hypertension and obesity alongside outcomes like diagnosis during COVID-19 pandemic implications within societal contexts are highlighted here too.Conclusion: Presently focused research on COPD coupled with CHD primarily revolves around five key areas: pathogenesis exploration, early diagnostic techniques, COVID-19 infection, dynamics intervention, methodologies, and treatment protocol development efforts. To improve the early detection rate of COPD complicated with CHD, the main development direction in the future is to extract computed tomography (CT) features using imaging omics and establish an early prediction model. The results of this study will provide new ideas and directions for subsequent related research.Keywords: chronic obstructive pulmonary disease, COPD, coronary heart disease, CHD, inflammation, bibliometrics, visual analysis

However, there is a notable lack of research focusing on their prognostic implications specifically in the early stage of gastric cancer. This study aims to investigate the prognostic indicators of early gastric cancer (EGC), including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), SII, PNI, and lymph node metastasis (LNM).Methods: In this retrospective analysis, we examined 490 patients diagnosed with EGC (pT1Nx). The peripheral blood indices of interest were SII, PNI, PLR, and NLR. The receiver operating characteristic (ROC) curves and the area under the ROC curve (AUC) were used to determine optimal cutoff values and prognostic efficacy for each parameter. Additionally, Kaplan-Meier survival curves and multivariate Cox regression models were utilized to delineate independent prognostic factors.Results: The optimal cutoff values for SII and PNI were determined as 613.05 and 42.21, respectively. Patients in the low SII (SII-L) group demonstrated significantly higher 5-year Disease-Free Survival (DFS) and Overall Survival (OS) rates of 94.7% and 96.2%, compared to the high SII (SII-H) group (DFS: 78.7%; OS: 81.9%), with both differences proving statistically significant (P < 0.001, P < 0.001). Similarly, patients in the high PNI (PNI-H) group showed superior 5-year DFS (93.3%) and OS rates (95.1%) versus the low PNI (PNI-L) group (DFS: 71.4%; OS: 74.3%), also demonstrating statistical significance (P < 0.001, P < 0.001). Multivariate analysis identified SII, PNI, and LNM as independent prognostic factors for EGC. A combined analysis of SII, PNI, and LNM yielded a C-index of 0.723 (P = 0.008).Conclusion: SII, PNI, and LNM are effective markers for predicting the survival outcomes of patients undergoing radical gastrectomy for EGC.Keywords: early gastric cancer, systemic inflammatory response index, prognostic nutritional index, lymph node metastasis, prognosis

Gluconeogenesis, a critical metabolic pathway, is responsible for the synthesis of glucose in the normal liver. This study aimed to examine the role of gluconeogenesis-related genes (GRGs) in HCC and evaluate their impact on the tumor microenvironment infiltration and drug sensitivity in HCC.Methods: We retrieved gene expression and clinical pathological data of HCC from The Cancer Genome Atlas (TCGA) database. This dataset was utilized to develop a prognosis model. The data from The International Cancer Genome Consortium (ICGC) served as an independent validation cohort. A least absolute shrinkage and selection operator (LASSO) regression analysis was applied to a curated panel of GRGs to construct and validate the predictive model. Furthermore, unsupervised consensus clustering, based on the expression levels of GRGs, categorized HCC patients into distinct subgroups.Results: A four-gene prognostic model, referred to as GRGs, has been successfully developed with high accuracy and stability for the prediction of HCC patient prognosis. This model enables the stratification of patients into high or low risk groups based on individual risk scores, revealing significant differences in immune infiltration patterns and anti-tumor drug responses. Unsupervised consensus clustering analysis delineated four distinct subgroups of patients, each characterized by a unique prognosis and tumor immune microenvironment (TIME).Conclusion: This study is the first to develop a prognostic model incorporating 4-GRGs that effectively predicts the prognosis, tumor microenvironment infiltration, and drug sensitivity in HCC patients. The model based on 4 GRGs may contribute to predict the prognosis, immunotherapy and chemotherapy response of HCC patients.Keywords: hepatocellular carcinoma, gluconeogenesis metabolism, prognostic model, tumor microenvironment infiltration, drug sensitivity

Based on its good hemostatic efficacy, it is mainly used clinically for bleeding in trauma, various types of surgical and dental procedures and prevention of bleeding in patients with hemophilia. In recent years, studies have shown that TXA has the effects of anti-melanogenesis, anti-inflammation, anti-angiogenesis and promotes the recovery of the skin barrier, so it has been tried to be used as a treatment for hyperpigmentation and telangiectatic diseases. Oral, topical, intradermal injections and microneedling are all commonly used modes of administration. TXA for melasma is the most studied and has achieved indications in some countries, whereas it is still an off-label drug for many other dyschromia. We review the clinical use of TXA in hyperpigmentation and telangiectatic disorders other than melasma, such as post-inflammatory hyperpigmentation, Riehl’s melanosis, rosacea, and post-acne erythema, to provide more evidence for the use of TXA in these disorders, and to provide safer and more cost-effective alternatives for the treatment of these diseases.Keywords: tranexamic acid, hyperpigmentation, erythema, telangiectatic disorder

The aim of this study was to detect fatigue rate and to evaluate factors associated with fatigue in NAFLD patients.Patients and Methods: A cross-sectional study was carried out from the Huadong Sanatorium between April 2022 and May 2023, and 133 NAFLD patients were included in this study. They completed Fatigue Severity Scale to assess fatigue, the Hospital Anxiety and Depression Scale to estimate psychological status, and the Pittsburgh Sleep Quality Index for sleep quality. Data were analyzed by independent samples t-tests, χ 2 tests and logistic regression models.Results: We found that 51.1% of NAFLD patients had fatigue. Exercise, anxiety, depression, subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disorders, daytime dysfunction and overall sleep quality were related to fatigue among NAFLD patients. Moreover, logistic regression models indicated anxiety, habitual sleep efficiency and sleep disorders as important predictors of fatigue.Conclusion: This was the first time to explore demographic, clinical, psychological and sleeping correlated factors for fatigue in Chinese NAFLD patients. Our study showed that more than half of NAFLD patients had fatigue, and anxiety, habitual sleep efficiency and sleep disorders were significantly associated with fatigue in NAFLD. The findings indicated that it was very necessary to pay more attention to fatigue of NAFLD patients, especially those with negative emotions and poor sleep quality by favorable intervention to relieve fatigue symptoms, so as to improve quality of life.Keywords: non-alcoholic fatty liver disease, fatigue, exercise, anxiety, sleep

Healthy controls were collected in a 1:1 ratio from the same hospital’s physical examination center. All participants underwent SMI and power Doppler ultrasound (PDUS) of the rotator cuff gap.Results: The study included 79 patients with frozen shoulder and 77 healthy controls. Compared with the healthy control group, the patient group had a higher proportion of hypoechoic rotator cuff gap (81.0% vs 48.1%, P< 0.001), a thicker coracohumeral ligament (2.60± 1.01 vs 2.03± 0.97, P< 0.001), a thicker glenohumeral joint capsule (3.10± 0.99 vs 2.46± 1.17, P< 0.001), and elevated blood grading using SMI (P< 0.001) and PDUS (P=0.014). The highest area under the curve (AUC) was observed for SMI blood flow grading (AUC=0.824, 95% CI: 0.755– 0.880, P< 0.001), resulting in 82% sensitivity and 77% specificity when using a cutoff of 1. SMI blood flow grading was associated with external rotation < 30° (P=0.007) and abduction < 30° (P=0.013) but not with internal rotation < 30° (P=0.630) or flexion < 30° (P=0.562).Conclusion: The grading of SMI blood flow may emerge as a valuable predictive indicator for the early stages of frozen shoulder. This simple ultrasound technique holds the potential to enhance the diagnostic process, enabling early initiation of treatment and potentially improving patient outcomes.Keywords: adhesive capsulitis of the shoulder, microcirculation, ultrasonography, early diagnosis, predictive value

Among these, zeolitic imidazolate framework-8 (ZIF-8) stands out as a widely utilized MOF known for its robust stability in aqueous environments owing to the robust interaction between its constituent zinc ions (Zn2+) and 2-methylimidazole (2-MIM). ZIF-8 readily decomposes under acidic conditions, serving as a promising candidate for pH-responsive drug delivery systems. Moreover, biomimetic materials typically possess good biocompatibility, reducing immune reactions. By mimicking natural structures or surface features within the body, they enhance the targeting of nanoparticles, prolong their circulation time, and increase their bioavailability in vivo. This review explores the latest advancements in biomimetic ZIF-8 nanoparticles for drug delivery, elucidating the primary obstacles and future prospects in utilizing ZIF-8 for drug delivery applications.Keywords: MOF, ZIF-8, cell membrane, biomimetic drug delivery

Beyond its structural significance, collagen is implicated in various diseases or cancers, notably breast cancer, where it influences crucial cellular processes including proliferation, metastasis, apoptosis, and drug resistance, intricately shaping cancer progression and prognosis. In breast cancer, distinct collagens exhibit differential expression profiles, with some showing heightened or diminished levels in cancerous tissues or cells compared to normal counterparts, suggesting specific and pivotal biological functions. In this review, we meticulously analyze the expression of individual collagen members in breast cancer, utilizing Transcripts Per Million (TPM) data sourced from the GEPIA2 database. Through this analysis, we identify collagens that deviate from normal expression patterns in breast cancer, providing a comprehensive overview of their expression dynamics, functional roles, and underlying mechanisms. Our findings shed light on recent advancements in understanding the intricate interplay between these aberrantly expressed collagens and breast cancer. This exploration aims to offer valuable insights for the identification of potential biomarkers and therapeutic targets, thereby advancing the prospects of more effective interventions in breast cancer treatment.Keywords: collagen, breast cancer, extracellular matrix, prognostic marker

A total of 462 and 199 patients served as the training and validation sets, respectively. Pre-operative blood markers were collected and analyzed for LFNII. The LFNII score was formulated using the least absolute shrinkage and selection operator Cox regression model. A nomogram model was developed using the training set to incorporate other relevant clinicopathological indicators and predict postoperative recurrence. Model discrimination was assessed using the receiver operating characteristic curve, calibration was evaluated using a calibration curve, and clinical applicability was assessed using clinical decision curve analysis. A comparison with liver cancer staging was performed using the nomogram model. Finally, a cohort study was conducted to validate our findings.Results: We derived the LFNII scores from nine indicators. Elevated LFNII scores correlated with unfavorable clinicopathological features. The LFNII score area under the curve revealed superior predictive efficacy at 1-, 2-, and 5-year RFS intervals, with values of 0.675, 0.658, and 0.633, respectively. Multivariate Cox analysis revealed that a high LFNII score independently increased RFS risk in patients with AFP-NHCC. The C-index of the LFNII-nomogram model was 0.686 (95% confidence interval [CI], 0.651– 0.721). The nomogram model’s clinical application value surpassed that of standard HCC staging systems.Conclusion: The LFNII score-derived nomogram effectively predicted the RFS of patients with AFP-NHCC after curative resection.Keywords: hepatocellular carcinoma, alpha-fetoprotein-negative, immunity, inflammation, nutrition, recurrence-free survival

These versatile cells serve myriad functions, including the regulation of vascular tension and the management of hemostasis and thrombosis. Inflammation constitutes a cascade of biological responses incited by biological, chemical, or physical stimuli. While inflammation is inherently a protective mechanism, dysregulated inflammation can precipitate a host of vascular pathologies. ECs play a critical role in the genesis and progression of vascular inflammation, which has been implicated in the etiology of numerous vascular disorders, such as atherosclerosis, cardiovascular diseases, respiratory diseases, diabetes mellitus, and sepsis. Upon activation, ECs secrete potent inflammatory mediators that elicit both innate and adaptive immune reactions, culminating in inflammation. To date, no comprehensive and nuanced account of the research progress concerning ECs and inflammation in vascular-related maladies exists. Consequently, this review endeavors to synthesize the contributions of ECs to inflammatory processes, delineate the molecular signaling pathways involved in regulation, and categorize and consolidate the various models and treatment strategies for vascular-related diseases. It is our aspiration that this review furnishes cogent experimental evidence supporting the established link between endothelial inflammation and vascular-related pathologies, offers a theoretical foundation for clinical investigations, and imparts valuable insights for the development of therapeutic agents targeting these diseases.Keywords: endothelial cells, endothelial inflammation, vascular-related diseases, atherosclerosis, diabetes mellitus, cardiovascular diseases

We aimed to evaluate the reliability of the systematic reviews/meta-analyses (SRs/MAs) evidence regarding acupuncture treatment of PSCI.Methods: The methodological quality was appraised with Methodological Quality of Systematic Reviews 2 (AMSTAR-2). We evaluated reporting quality with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and evidence quality with Grade of Recommendation, Assessment, Development and Evaluation (GRADE) system.Results: The inclusion criteria were met by fifteen reviews. All studies assessed by AMSTAR-2 had critically poor methodological quality due to the limitations on the lack of the provision of the list of excluded trails, screening of duplicate study, and protocol registration. For reporting quality, response rate of “yes” was less than 50% in Q5 (protocol and registration topic), Q8 (Search) and Q23 (Additional analysis). Evidence quality of outcome measures was low or worse with GRADE because when the data was qualitatively synthesized, low quality and small sample size trials provided the data.Conclusion: Acupuncture may be beneficial for PSCI. Because of limitations and inconsistent conclusions, further research is needed to provide higher evidence for acupuncture on PSCI.Keywords: acupuncture, treatment, cognitive impairment, stroke, evidence

Therefore, tissue engineering research using MSCs as seed cells is a current trending directions. However, the healing effect of direct cell transplantation is unstable, and the paracrine/autocrine effects of MSCs cannot be effectively elicited. Tumorigenicity and heterogeneity are also concerns. The combination of MSCs as seed cells and appropriate vector materials can form a stable cell growth environment, maximize the secretory features of stem cells, and improve the biocompatibility and mechanical properties of vector materials that facilitate the delivery of drugs and various secretory factors. There are numerous studies on tissue engineering and inflammation of various biomaterials, mainly involving bioceramics, alginate, chitosan, hydrogels, cell sheets, nanoparticles, and three-dimensional printing. The combination of bioceramics, hydrogels and cell sheets with stem cells has demonstrated good therapeutic effects in clinical applications.

To better understand the potential complexity of effects, this study sought to explore (a) the mediating role of meaning of life in the association between self-compassion and authentic-durable happiness and (b) the moderating role of COVID-19 burnout in the relationship between self-compassion and meaning of life.Methods: We conducted a cross-sectional online survey study in China from February 1 to 14, 2021. Online survey questionnaire technique and convenience sampling method were used for data collection. Participants anonymously completed the measures of self-compassion scale short form, COVID-19 burnout scale, meaning in life questionnaire, and subjective authentic-durable happiness scale. The data were examined utilizing Pearson’s r correlations and moderated mediation analysis.Results: This study included 1165 Chinese college students (Mage = 19.68 years, SD = 1.37). Self-compassion (M = 3.39, SD = 0.49) was significantly positively associated with authentic-durable happiness (M = 3.82, SD = 0.66) (r = 0.45, p < 0.001), and mediation analyses indicated that meaning of life (M = 4.65, SD = 0.86) partially mediated this association (indirect effect = 0.103, SE = 0.016, 95% CI = [0.073, 0.135]). Moderated mediation analysis further revealed that COVID-19 burnout (M = 1.87, SD = 0.72) buffered the relation between self-compassion and meaning of life (β = − 0.05, p < 0.033).Discussion and Conclusion: Findings of this study shed light on a correlation between self-compassion and authentic-durable happiness. In addition, this study underlines the importance of intervening in COVID-19 burnout among college students and enhancing the meaning of life in order to promote and safeguard authentic-durable happiness in the setting of COVID-19.Keywords: coronavirus, students, self-compassion, meaning of life, happiness, psychological burnout

These two processes are in dynamic balance to maintain a constant amount of bone for accomplishing its critical functions in daily life. Multiple cell type communications are involved in these two complex and continuous processes. In recent decades, an increasing number of studies have shown that osteogenic and osteoclastic extracellular vesicles play crucial roles in regulating bone homeostasis through paracrine, autosecretory and endocrine signaling. Elucidating the functional roles of extracellular vesicles in the maintenance of bone homeostasis may contribute to the design of new strategies for bone regeneration. Hence, we review the recent understandings of the classification, production process, extraction methods, structure, contents, functions and applications of extracellular vesicles in bone homeostasis. We highlight the contents of various bone-derived extracellular vesicles and their interactions with different cells in the bone microenvironment during bone homeostasis. We also summarize the recent advances in EV-loaded biomaterial scaffolds for bone regeneration and repair.Keywords: bone, homeostasis, metabolism, extracellular vesicles, regeneration

We sought to develop and validate a multivariable model to predict the all-cause mortality risk in patients with acute VTE in emergency settings.Methods: A total of 700 patients were included from Qilu Hospital of Shandong University and were randomly assigned into training set (n=490) and validation set (n=210) in an 7:3 ratio. Multivariate logistics regression analysis was performed to identify independent variables and develop a prediction model, which was validated internally using bootstrap method. The discrimination, calibration and clinical utility were evaluated by receiver operating characteristic curve (ROC) analysis, Hosmer-Lemeshow (HL) test, Kaplan-meier (KM) analysis and decision curve analysis (DCA).Results: There were 52 patients (10.6%) dying and 437 (89.4%) surviving in training set. Age (odds ratio [OR]: 4.158, 95% confidence interval [CI]: 2.426– 7.127), pulmonary embolism (OR: 1.779, 95% CI: 1.124– 2.814), platelet count (OR: 0.507, 95% CI: 0.310– 0.830), D-dimer (OR: 1.826, 95% CI: 1.133– 2.942) and platelet/lymphocyte ratio (OR: 2.166, 95% CI: 1.259– 3.727) were independent risk variables associated with all-cause mortality. The model had good predictive capability with an AUC of 0.746 (95% CI: 0.668,0.825), a sensitivity of 0.769 (95% CI: 0.607,0.889), a specificity of 0.672 (95% CI: 0.634,0.707). The validation model had an AUC of 0.739 (95% CI: 0.685,0.793), a sensitivity of 0.690 (95% CI: 0.580,0.787), a specificity of 0.693 (95% CI: 0.655,0.729). The model is well calibrated and the HL test showed a good fit (χ2=5.291, p=0.726, Nagelkerke R2=0.137). KM analysis and DCA showed a good clinical utility of the nomogram.Conclusion: This study identified independent variables affecting all-cause mortality in patients with acute VTE, and developed a prediction model and provided a nomogram with good prediction capability and clinical utility.Keywords: venous thromboembolism, prediction model, mortality, risk variable, platelet/lymphocyte ratio

We evaluated the ability of Circul to detect obstructive sleep apnea in Chinese adults.Methods: We recruited 207 Chinese Han subjects: 70% males, mean age 48.2± 14.7 years, mean BMI 27.6± 4.8 kg/m2 and mean AHI 28.6± 25.2 events/h. All participants underwent simultaneous polysomnography (PSG) and Circul testing in a sleep laboratory. Oxygen desaturation index (ODI), mean oxygen saturation (MSpO2), cumulative time at SpO2< 90% (CT90), cumulative percentage of sleep time spent with SpO2< 90% (CT90/TST) were derived and compared for the Circul and the PSG.Results: The ODI was 25.3± 24.5 events/h using PSG and 22.2± 24.5 events/h using Circul (P< 0.0001), with an intraclass correlation coefficient (ICC) of 0.884. CT90 and CT90/TST between the two methods were not different; the MSpO2 level calculated by PSG was slightly lower than Circul, 95.0% (93.0– 96.0%) vs 95.3% (93.9– 96.6%), P< 0.0001. Circul-ODI had a good correlation (r=0.91, p< 0.0001) and close agreement with PSG-AHI (Bland-Altman analysis: Mean Difference 6.4, 95% CI − 14.8 to 27.5 events/h). Using a threshold of AHI ≥ 5 events/h, the Circul had 87% sensitivity, 83% specificity, 5.09 positive likelihood ratio (LR+), 86% accuracy, and 0.929 area under the curve (AUC).Conclusion: Circul ring pulse oximetry can detect OSA with reasonable reliability. The Circul system is a reliable and comfortable choice for OSA assessment.Keywords: obstructive sleep apnea, reflective photoplethysmography, pulse oximetry, polysomnography

However, a new study suggests that underdog expectations may encourage employees to work harder, resulting in positive effects. Based on regulatory focus theory, this study constructed a moderated double-mediation model to explain the “double-edged sword effect” of underdog expectations.Subjects and Methods: A three-wave survey method and leader–employee pairing method were used to conduct a questionnaire survey among 346 employees drawn from five enterprises in Shanghai, China. Statistical analysis methods, including hierarchical regression analysis, simple slope analysis, and difference analysis, were used for data analysis. SPSS 24.0, Amoss 24.0, and Mplus 7.4 software were employed to test four proposed hypotheses.Results: Under the positive moderating effect of prevention focus, underdog expectations reduce employee work engagement by adopting an avoidance path of employee feedback-avoiding behaviors(β = 0.090, p < 0.01). Moreover, underdog expectations play a negative role in this situation . Under the positive moderating effect of promotion focus, underdog expectations improve employee work engagement by adopting an approach of proving others wrong (β = 0.189, p < 0.001). Moreover, underdog expectations play a positive role in this situation.Conclusion: The study results refined the double-sided effects of underdog expectations on employee work engagement and provided theoretical and practical implications for managers on how to motivate employees with underdog expectations and how to better convey expectations to subordinates.Keywords: underdog expectations, regulatory focus theory, prove others wrong, feedback-avoiding behaviors

Both chronic hepatitis B (CHB) and MAFLD have been independently attributed to an increased risk of disease development to cirrhosis. However, it is still unclear whether MAFLD is associated with an increased risk of cirrhosis in CHB patients.Aim: This study aimed to analyze the impact of MAFLD on the risk of cirrhosis in CHB patients.Methods: In this retrospective cohort study, consecutive CHB patients with or without MAFLD were enrolled from January 1st, 2007, to May 1st, 2020, in Guangdong Provincial Hospital of Chinese Medicine. Inverse probability treatment weighting (IPTW) was performed to balance the covariates across groups. The weighted Kaplan–Meier analysis and Cox regression analysis were used to compare both groups for the risk of cirrhosis.Results: A total of 1223 CHB patients were included in this study during the median follow-up of 5.25 years; of these patients, 355 were CHB-MAFLD patients. After IPTW, the weighted Kaplan–Meier analysis showed that the weighted cumulative incidence of cirrhosis was significantly higher in patients with MAFLD than that in patients without MAFLD (12.6% versus 7.1%, P=0.015). In the weighted multivariate Cox analysis, coexisting MAFLD was related to an increased risk of cirrhosis [adjusted weighted hazard ratio (HR) 1.790; P =0.020]. Age (> 40 years, adjusted weighted HR, 1.950; P=0.015), diabetes mellitus (adjusted weighted HR, 1.883; P=0.041), non-antiviral treatment (adjusted weighted HR, 2.037; P=0.013), and baseline serum HBV DNA levels (> 2.4 log10 IU/mL, adjusted weighted HR, 1.756; P=0.045) were significant risk factors for cirrhosis.Conclusion: We found that MAFLD was associated with a higher risk of cirrhosis in CHB patients.Keywords: chronic hepatitis B, metabolic dysfunction-associated fatty liver disease, hepatic steatosis, cirrhosis

Although concurrent MAFLD is common in patients with HBV-related HCC, whether MAFLD increases the risk of poor prognosis in patients with HBV-related HCC remains unclear. This study aimed to investigate the impact of MAFLD on prognosis in patients with HBV-related HCC.Patients and Methods: In this retrospective cohort study, 549 patients with HBV-related HCC were enrolled from January 2010 to April 2020 in Guangdong Provincial Hospital of Chinese Medicine, including 169 patients with MAFLD (MAFLD group) and 380 patients without MAFLD (Non-MAFLD group). Propensity score matching (PSM) analysis was performed to balance the baseline characteristics. Kaplan–Meier survival curves were performed to compare the prognosis between the two matched groups. A multivariate Cox proportional hazards model was used to determine the risk factors for poor prognosis.Results: The median follow-up time for all patients was 20 (interquartile range 8– 40) months. We found concurrent MAFLD was associated with a significantly decreased PFS rate before and after PSM analysis. The 1-year, 2-year, and 3-year PFS rates for the MAFLD and Non-MAFLD groups after PSM were 61.3% and 70.8%, 43.9% and 54.5%, 31.1% and 41.8%, respectively. Cox multivariable analysis showed that concurrent MAFLD was an independent risk factor for poor prognosis (death or progression) (HR = 1.49, P = 0.001). More interestingly, the risk of poor prognosis was significantly higher in the MAFLD subtype with metabolic components ≥ 2 compared to those with metabolic components < 2 (HR = 1.97, P < 0.001).Conclusion: Concurrent MAFLD was associated with a higher risk of poor prognosis in patients with HBV-related HCC, especially MAFLD with metabolic components ≥ 2.Keywords: hepatocellular carcinoma, hepatitis B virus, metabolic dysfunction-associated fatty liver disease, poor prognosis

Vector biomaterials embedded with mesenchymal stem cells (MSCs) are considered a promising treatment approach. In this study, we presented a novel and effective approach to accelerate diabetic skin wound healing.Methods and Materials: Human umbilical cord mesenchymal stem cells (hUC-MSCs) were shaped into spheres. RADA16-I, KLT, and RGD nanopeptides were selected for self-assembly into hydrogels. hUC-MSCs spheroids (hUC-MSCsp) were combined in vitro with self-assembled nanopeptide hydrogels and subsequently transplanted into a mouse model of diabetic skin trauma.Results: Compared with the PBS, hUC-MSCs, hUC-MSCsp, and hUC-MSCs with hydrogel groups, hUC-MSCsp with hydrogel significantly accelerated wound healing (p< 0.01) and shortened the healing time (10 vs 14 vs 21 days). The expressions of IL-6, IL-10, IL-1β, and TNF-α were significantly decreased (p< 0.001). The expression of VEGF was significantly higher in the hUC-MSCsp with hydrogel group (p< 0.05), and the density of neovascularization in the fresh skin tissue at the wound was also remarkably increased (p< 0.01).Conclusion: Nanopeptide hydrogels loaded with hUC-MSCsp accelerated diabetic skin wound healing by inhibiting inflammation and promoting angiogenesis compared with conventional stem cell transplantation, which deserves further investigation.Keywords: diabetic wound, human umbilical cord mesenchymal stem cell, spheroid, nanopeptide hydrogels, treatment

Objective: To assess the efficacy and safety of iguratimod in adult patients with active axial spondyloarthritis (axSpA). Method: This randomized, double-blind, placebo-controlled clinical trial lasted for 28 weeks. Patients with axSpA were randomized 1:1 to receive iguratimod 25 mg twice daily or a placebo. All patients also took celecoxib 200 mg twice daily for the first 4 weeks and on demand from 4 to 28 weeks. The primary endpoints were ASAS20 at 4 weeks and the non-steroidal anti-inflammatory drug (NSAID) index at 28 weeks. Other assessment variables included ASAS40, ASAS5/6 response rates, Spondyloarthritis Research Consortium of Canada (SPARCC) scores, and adverse events. Results: In total, 35 patients completed the study and were included for analyses. The median (interquartile range) NSAID index was 43.8 (34.9–51.8) in the iguratimod group, which is significantly lower than 68.9 (42.5–86.4) in the placebo group (p = 0.025). ASAS response rates and changes in disease activity scores were similar between the iguratimod and placebo groups. Patients in the iguratimod group had more improvement in median (interquartile range) SPARCC scores for sacroiliac joints than did those in the placebo group [71% (54–100%) vs 40% (0–52%), p = 0.006]. Iguratimod combined with celecoxib was not associated with a greater risk of adverse effects than was monotherapy with celecoxib. No severe adverse events occurred. Conclusions: In the treatment of active axSpA, iguratimod has a potential NSAID-sparing effect, and may also reduce magnetic resonance imaging-assessed bone marrow oedema in sacroiliac joints. Iguratimod provides an additional treatment option for patients with active axSpA.Clinical trial registration numberChiCTR2000029112, Chinese Clinical Trial Registry () [ABSTRACT FROM AUTHOR]

However, whether immune/inflammatory indicators and other factors are associated with mortality in patients with IHES remains unclear.Patients and Methods: The clinical data and follow-up results of 167 patients with IHES were retrospectively analyzed using Cox regression analysis and receiver operating characteristic curve (ROC).Results: Of 167 patients, 120 were men (71.9%) and 47 were women (28.1%). The median age was 52 (36.0, 68.0) years. The median follow-up period was 42.8 (18.5, 75.1) months, during which all-cause mortality occurred in 26 patients (15.6%). Age (HR: 1.041, 95% CI: 1.015– 1.068; p = 0.002), lymphocyte counts (109/L, HR: 0.866, 95% CI: 0.816– 0.907; p = 0.013), platelet counts (109/L, HR: 0.994, 95% CI: 0.989– 0.999; p = 0.012) and NLR (HR: 1.161, 95% CI: 1.054– 1.280; p = 0.003) were independent risk factors for all-cause mortality. There was no relationship between PLR, and SII and all-cause mortality (p = 0.181 and 0.202, respectively). ROC analysis showed that the AUCs of age, lymphocyte count (109/L), platelet count (109/L) and NLR were 0.712 (95% CI: 0.601– 0.824), 0.584 (95% CI: 0.448– 0.719), 0.686 (95% CI: 0.560– 0.812), and 0.797 (95% CI: 0.695– 0.899), respectively, with sensitivities of 0.5, 0.462, 0.769, and 0.792, respectively, and specificities of 0.765, 0.745, 0.617, and 0.845, respectively. Kaplan–Meier analysis (Log rank test) showed that patients with age ≥ 73.5 years, lymphocyte count (109/L) < 1.45, platelet count (109/L) < 225 and NLR ≥ 2.54 had high mortality. Patients with high NLR (≥ 2.54) usually have multiorgan involvement, with cardiac involvement and skin involvement being the most common. Patients with NLR ≥ 2.54 had significantly higher absolute eosinophil counts (p = 0.047) and percentages (p = 0.041).Conclusion: We identified NLR for the first time as an independent predictive factor for all-cause mortality in patients with IHES, necessitating its further application in clinical practice.Keywords: idiopathic hypereosinophilic syndrome, mortality, risk variable, neutrophil/lymphocyte ratio

Suicidal ideation (SI) often precedes and predicts suicide attempt and death, is the most common suicidal phenotype and is over-represented in veterans. The genetic architecture of SI in the absence of suicide attempt (SA) is unknown, yet believed to have distinct and overlapping risk with other suicidal behaviors. We performed the first GWAS of SI without SA in the Million Veteran Program (MVP), identifying 99,814 SI cases from electronic health records without a history of SA or suicide death (SD) and 512,567 controls without SI, SA or SD. GWAS was performed separately in the four largest ancestry groups, controlling for sex, age and genetic substructure. Ancestry-specific results were combined via meta-analysis to identify pan-ancestry loci. Four genome-wide significant (GWS) loci were identified in the pan-ancestry meta-analysis with loci on chromosomes 6 and 9 associated with suicide attempt in an independent sample. Pan-ancestry gene-based analysis identified GWS associations with DRD2, DCC, FBXL19, BCL7C, CTF1, ANNK1, and EXD3. Gene-set analysis implicated synaptic and startle response pathways (q's

This article discusses the role of personal needs in epidemic control and linked psychological needs with management measures to propose intervention advice on curbing viral transmission in a systematic way.Methods: Based on case studies, we showed the integration of the Maslow’s Hierarchy of Needs in the COVID-19 risk chain. The analysis combined the micro-view from individual needs and macro influences from governmental measures. The proposed chain of vulnerabilities could help identify critical links of COVID-19 crisis management in case that cascading effects such as super-spread can be intercepted in time.Results: The article mainly focused on curbing the viral transmission timely whenever cluster of cases resurge. Considering the triggered activities from personal needs may facilitate the spread, minimizing the impact scale while managing the crisis could start with protecting vulnerable population, well governing potential hotspots, and necessary restrictions on group activities. Besides, “individual” protections combined with “institutional” solutions are strongly advocated. The worst scenario would be the governance link slackened or made mistakes, together with delayed identification, plus unprotected way of living and gathering. In order to cut the transmission in time, besides virus-blocking strategies and vaccination approach, screening measures in combination with the satisfaction of personal needs would help identify confirmed cases earlier. Publicizing the model citizen of being responsible could show needs’ satisfaction can live with the virus elimination. At the emergency response stage, it is also crucial to secure fewer loopholes in the health system and strengthen the self-protection barrier by all means.Conclusion: China’s experience offers a reference for the balance between the resurgence of clustered cases and sustained recovery. As long as the global pandemic continues, its impact on personal activities will not stop, and vice versa. The chain of vulnerabilities integrating psychological needs into the COVID-19 risk management can provide clear clues for cutting further transmission in an efficient and more socially acceptable way.Keywords: pandemic control experience, China, COVID-19, risk management
