ABSTRACT

BACKGROUND: Endoscopic submucosal dissection (ESD) is a reliable method to resect early esophageal cancer. Esophageal stricture is one of the major complications after ESD of the esophagus. Steroid prophylaxis for esophageal strictures, particularly local injection of triamcinolone acetonide (TA), is a relatively effective method to prevent esophageal strictures. However, even with steroid prophylaxis, stenosis still occurs in up to 45% of patients. Predicting the risk of stenosis formation after local TA injection would enable additional interventions in risky patients. AIM: To identify the predictors of esophageal strictures after steroids application. METHODS: Patients who underwent esophageal ESD and steroid prophylaxis and who were comprehensively assessed for lesion- and ESD-related factors at Southeast University Affiliated Zhongda Hospital between February 2018 and March 2023 were included in the study. The univariate and multivariate regression analyses were conducted to identify the predictors of stricture among patients undergoing steroid prophylaxis. RESULTS: A total of 120 patients were included in the analysis. In the oral prednisone and oral prednisone combined with local tretinoin injection groups, the stenosis rates were 44/53 (83.0%) and 56/67 (83.6%), respectively. Among them, univariate analysis showed that the lesion circumference (P = 0.01) and submucosal injection solution (P = 0.04) showed significant correlation with the risk of stenosis formation. Logistic regression analyses were then performed using predictors that were significant in the univariate analyses and combined with known predictors from previous reports, such as additional chemoradiotherapy and tumor location. We identified a lesion circumference < 5/6 (OR = 0.19; P = 0.02) and submucosal injection of sodium hyaluronate (OR = 0.15; P = 0.03) as independent predictors of on esophageal stricture formation. CONCLUSION: Steroid prophylaxis effectively prevents stenosis. Moreover, the lesion circumference and submucosal injection of sodium hyaluronate were independent predictors of esophageal strictures. Additional interventions should be considered in high-risk patients.

ABSTRACT

Objective: Skin wound exposed to complex external environment for a long time is highly susceptible to bacterial infection. Impact Statement: This work designs a Janus adhesive dual-layer hydrogel containing in situ silver nanoparticles (named PSAP/DXP@AgNPs) with integrated attack and defense to simultaneously kill the existing bacteria and prevent foreign bacterial contamination. Introduction: The current gauze dressing fixed by tape fails to well fit at skin wound and lacks intrinsic antibacterial property, making it highly prone to causing secondary infection. Moreover, foreign bacteria may contaminate the wound dressing during use, further increasing the risk of secondary infection. Methods: In this work, a Janus adhesive dual-layer PSAP/DXP@AgNPs hydrogel is prepared by sequentially building the PSAP gel layer containing zwitterionic poly(sulfobetaine methacrylamide) (PSBMA) on the DXP@AgNPs gel layer containing in situ catechol-reduced AgNPs. Results: The flexible PSAP/DXP@AgNPs can adapt shape change of skin and adhere to skin tissue with interfacial toughness of 153.38 J m-2 relying on its DXP@AgNPs layer, which is beneficial to build favorable fit. The in situ reduced AgNPs released from the DXP@AgNPs layer of PSAP/DXP@AgNPs exhibit obvious antibacterial effects against Escherichia coli and Staphylococcus aureus, with antibacterial rates of 99% and 88%, respectively. Meanwhile, the hydrated PSAP layer of PSAP/DXP@AgNPs containing PSBMA is able to prevent the bacterial contamination, decreasing the risk of secondary infection. Besides, cell experiments demonstrate that PSAP/DXP@AgNPs is biocompatible. Conclusion: The PSAP/DXP@AgNPs hydrogel with integrated attack and defense simultaneously possessing bacteria-killing and bacteria-antifouling properties is a potential alternative in treating infected skin wound.

ABSTRACT

Disruption of the estrous cycle affects fertility and reproductive health. Follicular dynamics are key to the regularity of the estrous cycle. We identified a novel lincRNA, HEOE, showing significant upregulation in the ovaries during the estrus phase across various pig breeds. Functional analysis revealed that HEOE is responsive to luteinizing hormone (LH) stimulation, modulating transcriptional suppression and alternative splicing in ovarian granulosa cells (GCs). This leads to increased GC apoptosis and inhibition of proliferation. Mechanistically, HEOE inhibits miR-16 maturation in the nucleus, and sequesters miR-16 in the cytoplasm, thereby collectively reducing miR-16's inhibition on ZMAT3, enhancing the expression of ZMAT3, a key factor in the p53 pathway and alternative splicing, thereby regulating follicular development. This effect was validated in both mice and pig follicles. Persistent overexpression or suppression of HEOE throughout the estrous cycle impairs cycle regularity and reduces litter size. These outcomes are associated with HEOE reduced follicular PGF2α levels and modulation of the cAMP signaling pathway. Our data, combined with public databases, indicate that the high expression of HEOE during the estrus phase is crucial for maintaining the estrous cycle. HEOE is a potential therapeutic target for regulating fertility and ensuring estrous cycle regularity in pigs.

ABSTRACT

Autism Spectrum Disorder (ASD) is a prevalent neurological condition with multiple co-occurring comorbidities that seriously affect mental health. Precisely diagnosis of ASD is crucial to intervention and rehabilitation. A single modality may not fully reflect the complex mechanisms underlying ASD, and combining multiple modalities enables a more comprehensive understanding. Here, we propose, DeepASD, an end-to-end trainable regularized graph learning method for ASD prediction, which incorporates heterogeneous multimodal data and latent inter-patient relationships to better understand the pathogenesis of ASD. DeepASD first learns cross-modal feature representations through a multimodal adversarial-regularized encoder, and then constructs adaptive patient similarity networks by leveraging the representations of each modality. DeepASD exploits inter-patient relationships to boost the ASD diagnosis that is implemented by a classifier compositing of graph neural networks. We apply DeepASD to the benchmarking Autism Brain Imaging Data Exchange (ABIDE) data with four modalities. Experimental results show that the proposed DeepASD outperforms eight state-of-the-art baselines on the benchmarking ABIDE data, showing an improvement of 13.25% in accuracy, 7.69% in AUC-ROC, and 17.10% in specificity. DeepASD holds promise for a more comprehensive insight of the complex mechanisms of ASD, leading to improved diagnosis performance.

ABSTRACT

Hepatocellular carcinoma (HCC) is a serious health issue due to its low early diagnosis rate, resistance to chemotherapy, and poor five-year survival rate. Therefore, it is crucial to explore novel diagnostic and therapeutic approaches tailored to the characteristics of HCC. Aggregation-induced emission (AIE) is a phenomenon where the luminescence of certain molecules, typically non-luminescent or weakly luminescent in solution, is significantly enhanced upon aggregation. AIE has been extensively applied in bioimaging, biosensors, and therapy. Fluorophore materials based on AIE (AIEgens) have a wide range of application scenarios and potential for clinical translation. This review focuses on recent advances in AIE-based strategies for diagnosing and treating HCC. First, the specific functional mechanism of AIE is described. Next, we summarize recent progress in the application of AIE for multimodal imaging, biosensor detection, and phototherapy. Finally, prospects and challenges for the AIE-based application in the diagnosis and therapy of HCC are discussed.

ABSTRACT

Disulfiram (DSF) is a safe drug with negligible toxicity and Cu-dependent anti-tumor efficacy. However, the accumulation and combination of DSF and Cu in non-tumor tissues leads to systemic toxicity owing to the formation of highly poisonous diethyldithiocarbamate (CuET). In addition, CuET-mediated tumor-killing reactive oxygen species may be weakened by intra-tumoral glutathione (GSH). Herein, a synergistic treatment was developed that utilized the oral delivery of DSF and an injectable polyphenol-copper (PA-Cu) hydrogel loaded with the glutamine uptake inhibitor 2-amino-4-bis(phenoxymethyl)aminobutane (V9302). The injectable hydrogels were synthesized by the Schiff base reaction of hydroxypropyl chitosan (HPCS) with a PA-Cu reversible cross-linking agent. Because of the dynamic coordination between PA and Cu, the PA-Cu/HPCS hydrogel gradually releases Cu2+, forming CuET with DSF. The released V9302 inhibits glutamine uptake, thereby suppressing GSH synthesis and enhancing the therapeutic efficacy of the in situ formed CuET. The synergistic effect of PA-Cu/HPCS/V9302 and DSF in eliminating intracellular GSH and killing tumor cells was validated by in vitro cell experiments. Animal experiments further confirmed that PA-Cu/HPCS/V9302 and DSF have an inhibitory effect on tumor growth while maintaining the biosafety of main organs.

ABSTRACT

To clarify the survival benefit of sequential curative treatment post transcatheter arterial chemoembolization (TACE) for Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC), we retrospectively analyzed HCC patients at a hospital. From July 2017 to July 2020, 787 treatment-naïve HCC patients underwent initial treatment; 77 (9.8%) meeting inclusion criteria were enrolled. Their initial treatments were TACE only (n = 68, 88.3%) or TACE with other treatments (n = 9, 11.7%). Median survival of the TACE-only group was 30 months. Treatment response was evaluated after 2 or 3 consecutive TACEs for patients (54/68, 79.4%) with available pre-/post-TACE computerized tomography (CT) or magnetic resonance imaging (MRI). Treatment responses was divided into 4 groups: complete (n = 14, 26%, group (Gr) 1), incomplete without new tumor growth (n = 28, 52.0%, Gr2), incomplete with new growth (n = 6, 11%, Gr3), and progression (n = 6, 11%, Gr4). Of Gr2, further treatment after TACE were had radiofrequency ablation (n = 13, Gr2a), TACE (n = 9, Gr2b), other modalities (n = 6, Gr2c. Gr2a's median survival was longer than Gr2b's (> 60 vs. 20 months, p = 0.007). Nine patients in Gr2a (69%, 9/13) achieved a complete response, but none in Gr2b (p = 0.001). Conclusively, in TACE-suitable BCLC stage B HCC patients, a partial response without new tumor growth can serve as an indicator of treatment effectiveness following initial TACE treatment. This can facilitate the selection of appropriate candidates to receive RFA, potentially resulting in improved patient survival.

ABSTRACT

Background: Sulfasalazine is a widely used anti-inflammatory medication for treating autoimmune disorders such as ulcerative colitis (UC), Crohn's disease, and rheumatoid arthritis. However, its safety profile has not been systematically evaluated in real-world settings. By analyzing the FDA Adverse Event Reporting System (FAERS) database, we identified risk signals associated with adverse reactions to sulfasalazine, offering valuable insights for clinical decision-making and risk management. Methods: Reports of adverse events (AEs) associated with sulfasalazine, covering the period from Q1 2004 to Q4 2023, were extracted from the FAERS database. Detailed case information was aggregated to assess demographic characteristics. The associations between sulfasalazine and adverse events were evaluated using the Proportional Reporting Ratio (PRR), Reporting Odds Ratio (ROR), Bayesian Confidence Propagation Neural Network (BCPNN), and Empirical Bayes Geometric Mean (EBGM). Results: We extracted 7,156 adverse event reports from the FAERS database where sulfasalazine was identified as the "Primary Suspect (PS)" drug. Using disproportionality analysis, we identified 101 preferred terms (PT) related to sulfasalazine across 24 organ systems. Notable adverse reactions consistent with the drug's labeling were observed, including Stevens-Johnson syndrome, agranulocytosis, eosinophilic pneumonia, and crystalluria. Additionally, novel positive signals not previously documented in the drug label were identified, including acute febrile neutrophilic dermatosis, aseptic meningitis, glomerulonephritis, and hepatosplenic T-cell lymphoma. Conclusion: Most of the adverse reaction findings in this study are consistent with previous clinical research, and we have also identified new potential AEs associated with sulfasalazine. These findings provide valuable insights for the safety monitoring and clinical application of sulfasalazine.

ABSTRACT

Objective: Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation (ROHHAD) is rare, and manifestations of autonomic dysregulation are diverse and may be overlooked. We aimed to evaluate the incidence of these manifestations. Methods: Patients with ROHHAD syndrome reported before and after 2019 were divided into groups 1 and 2. Patients who were diagnosed at three regional hospitals in China were included in group 3. We collected the age of each specific term of the ROHHAD (neurogenic tumor, NET) acronym and the detailed manifestations of each term, and compared them among the three groups. Results: A total of 16 patients were diagnosed within the 2-year period. Two had neurogenic tumors and cognitive and behavioral abnormalities before developing rapid obesity. At least 93.8% of the patients had ≥ 4 symptoms of autonomic dysregulation. When comparing autonomic dysregulation among groups 1-3, the rates of cardiovascular manifestations were NA vs 12.8% vs 81.2%; gastrointestinal disturbances were 11.4% vs 8.5% vs 62.5%; strabismus was 25.7% vs 12.8% vs 62.5%; sleep disturbance was NA vs 6.4% vs 50.0%; and abnormal pain threshold was NA vs 10.6% vs 25.0% (all P < 0.05). The rates of cognitive and behavioral abnormalities were NA vs 29.8% and 87.5% (P < 0.01). Conclusion: Rapid-onset obesity is not always the first sign of ROHHAD syndrome. Higher rates of autonomic dysregulation and cognitive and behavioral abnormalities with multiple manifestations of autonomic dysregulation coexisted in our cohort, indicating that evaluations of autonomic function and the limbic system should be strengthened when assessing this condition.

ABSTRACT

Liver fibrosis, arising from factors such as viral infections or metabolic disorders, represents an ongoing global health challenge and is a major risk factor for hepatocellular carcinoma. Unfortunately, there are no clinically approved drugs available for its treatment. Recent studies have illuminated the pivotal role of macrophage recruitment in the pathogenesis of liver fibrosis, presenting a potential therapeutic target. Therefore, it holds great promise to develop novel anti-fibrotic therapies capable of inhibiting this process. Herein, a drug-loaded biomimetic nanodecoy (CNV-C) is developed by harnessing genetically engineered cellular vesicles for the treatment of liver fibrosis. CNV-C is equipped with a C-C motif chemokine receptor 2 (CCR2)-overexpressed surface, enabling it to selectively neutralize elevated levels of C-C motif chemokine ligand 2 (CCL2), thereby reducing macrophage infiltration and the subsequent production of the fibrogenic cytokine transforming growth factor ß (TGF-ß). Moreover, curcumin, an anti-fibrotic agent, is loaded into CNV-C and delivered to the liver, facilitating its efficacy in suppressing the activation of hepatic stellate cells by blocking the downstream TGF-ß/Smad signaling. This combinational therapy ultimately culminates in the alleviation of liver fibrosis in a mouse model induced by carbon tetrachloride. Collectively, the findings provide groundbreaking proof-of-concept for employing genetically modified nanodecoys to manage liver fibrosis, which may usher in a new era of anti-fibrotic treatments.

ABSTRACT

Posttraumatic osteoarthritis (PTOA) is closely related to the inflammatory response caused by mechanical injury and leads to joint degeneration. Herein, we aimed to evaluate the role and underlying mechanism of NUMB in PTOA progression. Anterior cruciate ligament transection (ACLT)-induced rats and interleukin (IL)-1ß-treated chondrocytes were used as in vivo and in vitro models of PTOA, respectively. The NUMB overexpression plasmid (pcDNA-NUMB) was administered by intra-articular injection to PTOA model rats, and safranin O-fast green staining, the Osteoarthritis Research Society International (OARSI) scoring system, and HE staining were used to evaluate the severity of cartilage damage. The secretion of inflammatory cytokines (TNF-α, IL-1ß, and IL-6) and chondrocyte-specific markers (MMP13 and COL2A1) was detected via ELISA. Cell viability and apoptosis were evaluated by MTT and TUNEL assays. NUMB was expressed at lower levels in ACLT-induced PTOA rats and in IL-1ß-treated chondrocytes than in control rats and cells. NUMB overexpression enhanced cell viability and reduced cell apoptosis, inflammation and cartilage degradation in chondrocytes stimulated by IL-1ß. NUMB bound to BTRC to promote p-IκBα expression, resulting in NF-κB pathway inactivation. BTRC overexpression reversed the promoting effect of NUMB overexpression on cell viability and the inhibitory effects of NUMB overexpression on apoptosis, inflammation and cartilage degradation in IL-1ß-induced chondrocytes. In addition, overexpression of NUMB alleviated articular cartilage damage by repressing inflammation and cartilage degradation in ACLT-induced PTOA rats. Our data indicated that NUMB regulated PTOA progression through the BTRC/NF-κB pathway, which may be a viable therapeutic target in PTOA.

ABSTRACT

Human herpesvirus 8 (HHV-8) infection shows obvious regional and ethnic differences. Although studies have shown that these differences may be associated with lipid metabolism, to date, no large-scale studies have explored this. This study explored the seropositivity rate of HHV-8 among 2516 residents from 10 regions of northwest China and then the correlates of HHV-8 infection with lipid profile. The HHV-8 serological positivity rate was 15.6% among all residents. The HHV-8 seroprevalence ranged 11.2-27.6% among different ethnicities. Across different BMI levels, the positive rates of HHV-8 were 27.6%, 16.9%, and 13.6% for a BMI < 18.5, 18.5-24.9, and ≥25, respectively. HHV-8 seropositivity rate was lower for hypertensive people (12.6%) than for non-hypertensive people (16.7%). Univariate logistic regression analyses revealed that age, hypertension, systolic blood pressure, BMI, total cholesterol, and high-density lipoprotein cholesterol (HDL-C) significantly correlated with HHV-8 seropositivity (p < 0.05). Multivariate logistic regression analysis after adjusting for confounding factors showed that HDL-C (odds ratio [OR]: 0.132, 95% confidence interval [CI], 0.082-0.212; p < 0.001) and BMI (OR: 0.959, 95% CI 0.933-0.986; p = 0.003) were associated with HHV-8 seropositivity. Subgroup analyses concerning ethnicity, sex, or age demonstrated a consistent relationship with HDL-C. The results of HHV-8 seropositivity and BMI were inconsistent in the subgroups. However, Spearman's correlation analysis between HHV-8 serum antibody titer and HDL-C levels showed no linear relationship among HHV-8 seropositive individuals (ρ = -0.080, p = 0.058). HHV-8 serum antibody titers were also not significantly correlated with BMI (ρ = -0.015, p = 0.381). Low HDL-C levels may be an independent risk factor for HHV-8 infection, but there is no significant correlation between HDL-C levels and HHV-8 antibody titers.

ABSTRACT

BACKGROUND: The global burden of metabolic dysfunction-associated steatotic liver disease (MASLD) is growing, but its subsequent health consequences have not been thoroughly examined. METHODS: A phenome-wide association study was conducted to map the associations of MASLD with 948 unique clinical outcomes among 361,021 Europeans in the UK Biobank. Disease trajectory and comorbidity analyses were applied to visualize the sequential patterns of multiple comorbidities related to the occurrence of MASLD. The associations jointly verified by observational and polygenic phenome-wide analyses were further replicated by two-sample Mendelian randomization analysis using data from the FinnGen study and international consortia. FINDINGS: The observational and polygenic phenome-wide association study revealed the associations of MASLD with 96 intrahepatic and extrahepatic diseases, including circulatory, metabolic, genitourinary, neurological, gastrointestinal, and hematologic diseases. Sequential patterns of MASLD-related extrahepatic comorbidities were primarily found in circulatory, metabolic, and inflammatory diseases. Mendelian randomization analyses supported the causal associations between MASLD and the risk of several intrahepatic disorders, metabolic diseases, cardio-cerebrovascular disease, and ascites but found no associations with neurological diseases. CONCLUSIONS: This study elucidated multisystem comorbidities and health consequences of MASLD, contributing to the development of combination interventions targeting distinct pathways for health promotion among patients with MASLD. FUNDING: X.L. was funded by the Natural Science Fund for Distinguished Young Scholars of Zhejiang Province (LR22H260001) and the National Nature Science Foundation of China (82204019) and Y.D. was funded by the Key Project of Traditional Chinese Medicine Science and Technology Plan of Zhejiang Province (GZY-ZJ-KJ-24077) and the National Natural Science Foundation of China (82001673 and 82272860).

ABSTRACT

Many autologous melanocytes are required for surgical treatment of depigmentation diseases such as vitiligo. However, primary cultured melanocytes have a limited number of in vitro passages. The production of functional epidermal melanocytes from stem cells provides an unprecedented source of cell therapy for vitiligo. This study explores the clinical application of melanocytes induced by hair follicle neural crest stem cells (HFNCSCs). This study established an in vitro differentiation model of HFNCSCs into melanocytes. Results demonstrate that most differentiated melanocytes expressed the proteins C-KIT, MITF, S-100B, TYRP1, TYRP2, and tyrosinase. The HFNCSC-derived melanocytes were successfully transplanted onto the dorsal skin of mice and survived in the local tissues, expressing marker protein of melanocytes. In conclusion, HFNCSCs in mice can be induced to differentiate into melanocytes under specific conditions. These induced melanocytes exhibit the potential to facilitate repigmentation in the lesion areas of vitiligo-affected mice, suggesting a promising avenue for therapeutic intervention.

ABSTRACT

Large prospective studies are required to better elucidate the associations of physical activity, sedentary behaviors (SBs), and sleep with overall cancer and site-specific cancer risk, accounting for the interactions with genetic predisposition. The study included 360,271 individuals in UK Biobank. After a median follow-up of 12.52 years, we found higher total physical activity (TPA) level and higher sleep scores were related to reduced risk of cancer while higher SB level showed a positive association with cancer. Compared with high TPA-healthy sleep group and low SB-healthy sleep group, low TPA-poor sleep group and high SB-poor sleep group had the highest risk for overall cancer, breast cancer, and lung cancer. Adherence to a more active exercise pattern was associated with a lower risk of cancer irrespective of genetic risk. Our study suggests that improving the quality of sleep and developing physical activity habits might yield benefits in mitigating the cancer risk.

ABSTRACT

BACKGROUND: Metabolic dysfunction-associated fatty liver disease (MAFLD) is a significant health problem. Dietary intervention plays an important role in patients with MAFLD. OBJECTIVES: We aimed to provide a reference for dietary patterns in patients with MAFLD. METHODS: The presence of MAFLD was determined in the United Kingdom Biobank cohort. Nine dietary pattern scores were derived from the dietary records. Multivariable Cox regression models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs). The contrast test was employed to calculate the heterogeneity across MAFLD statuses. RESULTS: We identified 175,300 patients with MAFLD at baseline. Compared with non-MAFLD, MAFLD was significantly associated with chronic liver disease (CLD) (HR: 3.48; 95% CI: 3.15, 3.84), severe liver disease (SLD) (HR: 2.87; 95% CI: 2.63, 3.14), liver cancer (HR: 1.93; 95% CI: 1.67, 2.23), and liver-related death (LRD) (HR: 1.93; 95% CI: 1.67, 2.23). In the overall cohort, the alternate Mediterranean diet (aMED) (HRCLD: 0.53; 95% CI: 0.37, 0.76; HRSLD: 0.52; 95% CI: 0.37, 0.72), planetary health diet (PHD) (HRCLD: 0.62; 95% CI: 0.47, 0.81; HRSLD: 0.65; 95% CI: 0.51, 0.83), plant-based low-carbohydrate diet (pLCD) (HRCLD: 0.65; 95% CI: 0.49, 0.86; HRSLD: 0.66; 95% CI: 0.51, 0.85), and healthful plant-based diet index (hPDI) (HRCLD: 0.63; 95% CI: 0.47, 0.84; HRSLD: 0.61; 95% CI: 0.47, 0.78) were associated with a lower risk of CLD and SLD. Additionally, unhealthful plant-based diet index (uPDI) was associated with increased risk of CLD (HR: 1.42; 95% CI: 1.09,1.85), SLD (HR: 1.50; 95% CI: 1.19, 1.90), and LRD (HR: 1.88; 95% CI: 1.28-2.78). The aforementioned associations remained consistently strong within the MAFLD subgroup while exhibiting less pronounced in the non-MAFLD group. However, no significant heterogeneity was observed across different MAFLD statuses. CONCLUSIONS: These findings highlight the detrimental effects of MAFLD on the development of subsequent liver diseases and the importance of dietary patterns in managing MAFLD.

ABSTRACT

PURPOSE: Internal iliac artery ligation (IIAL) has been used as a damage control procedure to treat hemodynamically unstable pelvic fracture for many years. However, there is ongoing debate regarding the effectiveness and safety of this hemostatic method. Therefore, we performed a systematic literature review to assess the efficacy and safety of IIAL for pelvic fracture hemostasis. METHODS: Three major databases, PubMed, Embase, and Google Scholar, were searched to screen eligible original studies published in English journals. Two reviewers independently read the titles, abstracts, and full texts of all literature. Articles were included if they reported the use and effects of IIAL. RESULTS: A total of 171 articles were initially identified, with 22 fully meeting the inclusion criteria. Among the analyzed cases, up to 66.7% of patients had associated abdominal and pelvic organ injuries, with the urethra being the most frequently injured organ, followed by the bowel. The outcomes of IIAL for achieving hemostasis in pelvic fractures were found to be satisfactory, with an effective rate of 80%. Hemorrhagic shock was the leading cause of death, followed by craniocerebral injury. Notably, no reports of ischemic complications involving the pelvic organs due to IIAL were found. CONCLUSION: IIAL has a good effect in treating hemodynamically unstable pelvic fracture without the risk of pelvic organ ischemia.

ABSTRACT

PURPOSE: The aim of this study was to evaluate the diagnostic accuracy of the B1 inhomogeneity-corrected variable flip angle (VFA) method using native T1 values in the staging of liver fibrosis. METHODS: Eighty-three patients who presented for liver biopsy due to varying degrees of liver damage, underwent MR examinations and had T1-mapping images of the liver acquired using the B1 inhomogeneity-corrected VFA VIBE method. Among them, 65 patients underwent Fibroscan, and their results were used to evaluate the elasticity of liver tissue. Additionally, T1-mapping images were collected from 19 normal control patients. Independent sample t-tests were used to analyze the correlation between T1 mapping and Fibroscan. The diagnostic efficacy of T1 mapping in patients with different stages of liver fibrosis was evaluated using receiver operating characteristic (ROC) curves. RESULTS: The consistency between different observer groups was intraclass correlation coefficient (ICC) =0.802. T1 mapping demonstrated significant differences between mid-stage liver fibrosis (S = 2) and late-stage liver fibrosis (S = 3), as well as moderate inflammation (G = 2) and severe inflammation (G = 3), P < 0.05. The Area Under Curve(AUC) values of T1 mapping for early liver fibrosis (S ≥ 1), significant liver fibrosis (S ≥ 2), advanced liver fibrosis (S ≥ 3), and end-stage liver fibrosis (S = 4) were 0.760, 0.709, 0.790, and 0.768, respectively. T1 mapping combined with Fibroscan had an AUC value of 0.860. CONCLUSIONS: The B1 inhomogeneity-corrected VFA T1 mapping may be useful for the staging of liver fibrosis. It has a superior diagnostic efficiency for diagnosing advanced fibrosis (≥S3), while native T1 values combined with Fibroscan have potential value for the staging of liver fibrosis.

ABSTRACT

Hepatocellular injury, a pivotal contributor to liver diseases, particularly hepatitis, lacks effective pharmacological treatments. Interleukin-22 (IL-22), crucial for liver cell survival, shows potential in treating liver diseases by regulating repair and regeneration through signal transducer and activator of transcription 3 (STAT3) activation. However, the short half-life and off-target effects limit its clinical applications. To address these issues, lipid nanoparticles are employed to deliver synthetic IL-22 mRNA (IL-22/NP) for in situ IL-22 expression in hepatocytes. The study reveals that IL-22/NP exhibits liver-targeted IL-22 expression, with increased IL-22 levels detected in the liver as early as 3 h postintravenous injection, lasting up to 96 h. Furthermore, IL-22/NP activates STAT3 signaling in an autocrine or paracrine manner to upregulate downstream factors Bcl-xL and CyclinD1, inhibiting hepatocyte apoptosis and promoting cell proliferation. The therapeutic efficacy of IL-22/NP is demonstrated in both chronic and acute liver injury models, suggesting IL-22 mRNA delivery as a promising treatment strategy for hepatitis and liver diseases involving hepatocellular injury.

ABSTRACT

BACKGROUND: Hepatic ischemia reperfusion injury (HIRI) is a common injury not only during liver transplantation but also during major hepatic surgery. HIRI causes severe complications and affects the prognosis and survival of patients. Cuproptosis, a newly identified form of cell death, plays an important role in a variety of illnesses. However, its role in HIRI remains unknown. MATERIALS AND METHODS: The GSE151648 dataset was mined from the Gene Expression Omnibus (GEO) database, and differences were analyzed for intersections. Based on the differentially expressed genes (DEGs), functional annotation, differentially expressed cuproptosis-related genes (DE-CRGs) identification and lasso logistic regression were conducted. Correlation analysis of DE-CRGs and immune infiltration was further conducted, and DE-CRGs were applied to construct an HIRI diagnostic model. The hierarchical clustering method was used to classify the specimens of HIRI, and functional annotation was conducted to verify the accuracy of these DE-CRGs in predicting HIRI progression. The GSE14951 microarray dataset and GSE171539 single-cell sequencing dataset were chosen as validation datasets. At the same time, the significance of DE-CRGs was verified using a mouse model of HIRI with cuproptosis inhibitors and inducers. Finally, a network of transcription-factor-DE-CRGs and miRNA-DE-CRGs was constructed to reveal the regulation mechanisms. And potential drugs for DE-CRGs were predicted using Drug Gene Interaction Database (DGIdb). RESULTS: Overall, 2390 DEGs and 19 DE-CRGs were identified. Through machine learning algorithms, 8 featured DE-CRGs (GNL3, ALAS1, TSC22D2, KLF5, GTF2B, DNTTIP2, SLFN11 and HNRNPU) were screened, and 2 cuproptosis-related subclusters were defined. Based on the 8 DE-CRGs obtained from the HIRI model (AUC=0.97), the nomogram model demonstrated accuracy in predicting HIRI. Eight DE-CRGs were highly expressed in HIRI samples and were negatively related to immune cell infiltration. A higher level of immune infiltration and expression of CRG group B was found in the HIRI population. Differences in cell death and immune regulation were found between the 2 groups. The diagnostic value of the 8 DE-CRGs was confirmed in the validation of two datasets. The identification of 7 DE-CRGs (SLFN11 excluded) by HIRI animal model experiments was also confirmed. Using hTFtarget, miRWalk and DGIDB database, we predicted that 17 transcription factors, 192 miRNAs and 10 drugs might interact with the DE-CRGs. CONCLUSION: This study shows that cuproptosis may occur in HIRI and is correlated with immune infiltration. Additionally, a cuproptosis-related predictive model was constructed for studying the causes of HIRI and developing targeted treatment options for HIRI.
