OBJECTIVES: To observe the effect of electroacupuncture (EA) preconditioning at "Quchi" (LI11) and "Xuehai" (SP10) in prevention of urticaria. METHODS: Twenty-four male SD rats were randomly divided into control, model and preconditioning of EA (Pre-EA) groups (8 rats/group). The urticaria model was established by intradermal injection of dilute allogeneic antioalbumin serum at the spots of the bilateral symmetry of the spine on the back, and followed by tail venous injection of mixture solution of egg albumin diluent, plus 0.5% Evans blue and normal saline. Ten days before the end of modeling, rats of the pre-EA group received EA stimulation of LI11 and SP10 for 20 min, once a day for 10 consecutive days. The times of rat's scratching the sensitized skin were recorded. HE staining method was used to observe the pathological changes of skin tissue, and toluidine blue staining method was used to observe the morphology of mast cells (MCs) in the skin, blood, mesentery, and peritoneal fluid, and calculate the degranulation rate. Immunohistochemical stainning was used to detect immunoglobulin E (IgE), histamine (HIS), and 5-hydroxytryptamine (5-HT) expressions in subcutaneous tissue. NOD like receptor thermal domain associated protein 3 (NLRP3) inflammasome, apoptosis related granule protein (ASC), and cysteine aspartate aminotransferase 1 (Caspase-1) protein expression levels in skin tissue were detected by Western blot. The contents of serum interleukin(IL)-1ß and IL-18 were detected using ELISA method. RESULTS: Compared with the control group, the scratching times, amount of Evans blue exudation of the sensitized blue spots, degranulation rate of MCs in skin, blood, mesentery and peritoneal fluid, the expression levels of IgE, HIS, 5-HT in subcutaneous tissue, protein expression levels of NLRP3, ASC, Caspase-1 in skin tissue, and the contents of serum IL-1ß and IL-18 were significantly increased (P<0.01, P<0.05) in the model group. In comparison with the model group, the scratching times, amount of Evans blue exudation of the sensitized blue spots, degranulation rate of MCs, the expression levels of IgE, HIS, 5-HT in subcutaneous tissue, protein expression levels of NLRP3, ASC, Caspase-1 in skin tissue, and the contents of serum IL-1ß and IL-18 in EA group were significantly decreased (P<0.01, P<0.05). CONCLUSIONS: EA preconditioning at LI11 and SP10 can prevent and treat UR by inhibiting inflammatory response, which is related to the regulation of pyroptosis.

[Clinical Features and Prognosis of Patients with Diffuse Large B-Cell Lymphoma of the Breast].

OBJECTIVE: To explore the clinical characteristics and prognosis of patients with diffuse large B-cell lymphoma (DLBCL) of the breast. METHODS: The clinical data of 28 DLBCL patients admitted to Shanxi Provincial Cancer Hospital from January 2013 to January 2023 were retrospectively analysed, including 13 cases of primary breast DLBCL (PB-DLBCL) and 15 cases of secondary breast DLBCL (SB-DLBCL), and the data of their clinical manifestations, laboratory tests, pathological examinations, treatment protocols, and follow-up were statistically analyzed. RESULTS: There were significant differences in IPI score, LDH level and ß2- microglobulin between PB-DLBCL and SB-DLBCL patients (P < 0.05). Among the 23 patients with breast DLBCL who received regular treatment, 13 patients achieved complete remission (9 patients with PB-DLBCL and 4 patients with SB-DLBCL) after initial treatment. By the end of follow-up, 11 patients relapsed or progressed (5 patients with PB-DLBCL and 6 patients with SB-DLBCL) and 9 patients died (3 patients with PB-DLBCL and 6 patients with SB-DLBCL). The 5-year OS rate was (75.0±15.3)% in PB-DLBCL group and (32.3±17.1)% in SB-DLBCL group. The 5-year PFS rate was （59.1±19.8）% in PB-DLBCL and 0% in SB-DLBCL group. The 5-year OS rate and PFS rate of PB-DLBCL patients were higher than those of SB-DLBCL patients (P < 0.05); the 5-year OS rate of the combined central preventive treatment group was higher than that of the chemotherapy group (P < 0.05). CONCLUSION: Breast DLBCL is divided into two categories: PB-DLBCL and SB-DLBCL. Compared with SB-DLBCL, PB-DLBCL has the characteristics of lower IPI score, LDH, and ß2-microglobulin levels. PB-DLBCL patients have a longer survival period. In addition, the prognosis of patients receiving central preventive treatment is more optimistic.

Forsythoside B, the active component of Frosythiae fructuse water extract, alleviates Streptococcus pneumoniae virulence by targeting pneumolysin.

AIMS: To explore the therapeutic potential of Forsythoside B in treating Streptococcus pneumoniae (S. pneumoniae) infections, focusing on its ability to inhibit pneumolysin activity and protect cells from damage. METHODS AND RESULTS: Hemolysis tests were used to evaluate Forsythoside B's inhibitory effect on pneumolysin activity, while growth curve analysis assessed its impact on S. pneumoniae growth. Western blotting and oligomerization analysis were conducted to examine its influence on pneumolysin oligomerization. Cytotoxicity assays, including LDH release and live/dead cell staining, evaluated the protective effects of Forsythoside B against pneumolysin-induced damage in A549 cells. Additionally, a mouse model was employed to test the effects on survival rates, lung bacterial load, and inflammation. The results showed that Forsythoside B significantly inhibited pneumolysin activity, reduced its oligomerization, and protected A549 cells from damage without affecting bacterial growth. In the mouse model, it improved survival rates and reduced lung inflammation, indicating its potential as a therapeutic agent against S. pneumoniae infections. CONCLUSIONS: Forsythoside B shows potential as a therapeutic agent for treating pneumonia, particularly in infections caused by S. pneumoniae.

A Metalgel with Liquid Metal Continuum Immobilized in Polymer Network.

Gels are formed by fluids that expand throughout the whole volume of 3D polymer networks. To unlock unprecedented properties, exploring new fluids immobilized in polymer networks is crucial. Here, a new liquid metal-polymer gel material termed "metalgel" is introduced via fluid replacement strategy, featuring 92.40% vol liquid metal fluid as a continuum immobilized by interconnected nanoscale polymer network. The unique structure endows metalgel with high electrical conductivity (up to 3.18 × 106 S·m‒1), tissue-like softness (Young's modulus as low as 70 kPa), and low gas permeability (4.50 × 10‒22 m2·s‒1·Pa‒1). Besides, metalgel demonstrates electrical stability under extreme deformations, such as being run over by a 4.5-metric-tonne truck, and maintains its integrity in various environments for up to 180 days. The immobilization of high-volume-fraction liquid metal fluid is realized by electrostatic interactions is further revealed. Potential applications for metalgel are diverse and include soft electromagnetic shielding, hermetic sealing, and stimulating/sensing electrodes in implantable bioelectronics, underscoring its broad applicability.

Native Mass Spectrometry of Membrane Protein-Lipid Interactions in Different Detergent Environments.

Native mass spectrometry (MS) reveals the role of specific lipids in modulating membrane protein structure and function. Membrane proteins solubilized in detergents are often introduced into the mass spectrometer. However, detergents commonly used for structural studies, such as dodecylmaltoside, tend to generate highly charged ions, leading to protein unfolding, thereby diminishing their utility in characterizing protein-lipid interactions. Thus, there is a critical need to develop approaches to investigate protein-lipid interactions in different detergents. Here, we demonstrate how charge-reducing molecules, such as spermine and trimethylamine-N-oxide, enable the opportunity to characterize lipid binding to the bacterial water channel (AqpZ) and ammonia channel (AmtB) in complex with regulatory protein GlnK in different detergent environments. We find that protein-lipid interactions not only are protein-dependent but also can be influenced by the detergent and type of charge-reducing molecule. AqpZ-lipid interactions are enhanced in LDAO (n-dodecyl-N,N-dimethylamine-N-oxide), whereas the interaction of AmtB-GlnK with lipids is comparable among different detergents. A fluorescent lipid binding assay also shows detergent dependence for AqpZ-lipid interactions, consistent with results from native MS. Taken together, native MS will play a pivotal role in establishing optimal experimental parameters that will be invaluable for various applications, such as drug discovery as well as biochemical and structural investigations.

Accelerated Fe3+/Fe2+ cycle in Mo2C-based Fe catalyst to promote peroxymonosulfate activation.

The harmful impact of organic pollutants on aquatic ecosystems underscores the pressing need for effective remediation. While activating peroxymonosulfate (PMS) with Fe catalyst offers a promising approach for eliminating these pollutants, its widespread use is hindered by the sluggish regeneration of Fe2+ from Fe3+. Here, this study demonstrates for the first time that combining an Fe catalyst with Mo2C (Fe-Mo2C) enhances the Fe³âº/Fe2⁺ cycle, thereby improving PMS activation. The Fe-Mo2C/PMS system achieved near-complete degradation of carbamazepine (CBZ) within only 8 min, with an impressive observed rate constant (kobs) of up to 0.624 min-1, about 15 times greater than that of Fe-C catalyst. It also exhibits the capability to degrade a broad range of common antibiotics, phenols, and dye-like organic compounds. Through electron paramagnetic resonance (EPR) analysis and quenching experiments, it was verified that hydroxyl radicals (·OH), sulfate radicals (SO4·-), singlet oxygen (1O2), and superoxide radicals (·O2-) species during the reaction, with the former three serving as the primary active species. These findings offer a hopeful avenue for the systematic development and enhancement of catalysts specifically designed to efficiently remediate organic pollutants in wastewater.

Sources of Rapid and Delayed New Lower Jaw Input in the Forepaw Barrel Subfield (FBS) in Rat Primary Somatosensory Cortex (SI) Following Forelimb Deafferentation.

Previously, we reported an immediate emergence of new lower jaw input to the anterior forepaw barrel subfield (FBS) in primary somatosensory cortex (SI) following forelimb deafferentation. However, a delay of 7 weeks or more post-amputation results in the presence of this new input to both anterior and posterior FBS. The immediate change suggests pre-existing latent lower jaw input in the FBS, whereas the delayed alteration implies the involvement of alternative sources. One possible source for immediate lower jaw responses is the neighboring lower jaw barrel subfield (LJBSF). We used anatomical tracers to investigate the possible projection of LJBSF to the FBS in normal and forelimb-amputated rats. Our findings are as follows: (1) anterograde tracer injection into LJBSF in normal and amputated rats labeled fibers and terminals exclusively in the anterior FBS; (2) retrograde tracer injection in the anterior FBS in normal and forelimb-amputated rats, heavily labeled cell bodies predominantly in the posterior LJBSF, with fewer in the anterior LJBSF; (3) retrograde tracer injection in the posterior FBS in normal and forelimb-amputated rats, sparsely labeled cell bodies in the posterior LJBSF; (4) retrograde tracer injection in anterior and posterior FBS in normal and forelimb-amputated rats, labeled cells exclusively in ventral posterior lateral (VPL) nucleus and posterior thalamus (PO); (5) retrograde tracer injection in LJBSF-labeled cell bodies exclusively in ventral posterior medial thalamic nucleus and PO. These findings suggest that LJBSF facilitates rapid lower jaw reorganization in the anterior FBS, whereas VPL and/or other subcortical sites provide a likely substrate for delayed reorganization observed in the posterior FBS.

Spatial confined synthesis of submicron Fe-MoS2 with abundant surface cationic groups and sulfur vacancies for enhanced peroxymonosulfate activation.

The widespread use of emerging refractory organic contaminants poses a significant threat to human health, prompting the need for a cost-effective and efficient removal strategy. While the iron ions/PMS system effectively removes organic pollutants, slow Fe3+ to Fe2+ transformation hampers its efficiency, and the homogeneous distribution of iron ions complicates separation, resulting in secondary sludge pollution. Herein, we developed a novel submicron Fe-MoS2 (S-Fe-MoS2) catalyst with abundant surface cationic groups and sulfur vacancy through a cationic polyacrylamide aerogels (CPAMA) confined hydrothermal synthesis strategy. These features promote active site exposure, enhance reactant adsorption, and accelerate electron transfer between Mo and Fe sites, improving catalytic kinetics and promoting Fe3+/Fe2+ cycle for PMS activation. As a result, the S-Fe-MoS2/PMS system exhibited a high catalytic rate constant (kobs) of 0.32 min-1, in the degradation of 4-chlorophenol (4-CP), 1.5 times higher than that of the conventional Fe-MoS2/PMS system. It also achieved 82.9% total organic carbon (TOC) degradation within 60 min. Additionally, it possessed similar degradation performance for various organic pollutants, along with remarkable reusability (four cycles) and broad pH adaptability (2-8), indicating significant potential for widespread application. This study provided a new way for developing advanced heterogeneous catalysts with high efficiency for water treatment.

Clinical effect of spleen aminopeptide on improving liver function damage and immune function in children with infant hepatitis syndrome.

BACKGROUND: Infant hepatitis syndrome (IHS) is a clinical syndrome in infants less than one year of age with generalized skin jaundice, abnormal liver function, and hepatomegaly due to various etiologies such as infection. AIM: To investigate the effect of IHS patients, after treatment with arsphenamine-based peptides, on patients' liver function damage and immune function. METHODS: Of 110 patients with IHS treated in our hospital from January 2019 to January 2021 were grouped according to the randomized residual grouping method, with 5 cases in each group shed due to transfer, etc. Ultimately, 50 cases remained in each group. The control group was treated with reduced glutathione, and the treatment group was treated with sesquiterpene peptide based on the control group. Observe and compare the differences in indicators after treatment. RESULTS: The comparison of serum total bilirubin, direct bilirubin, and serum alanine transferase after treatment was significantly different and lower in the treatment group than in the control group (P < 0.05). The comparison of CD4+, CD3+, CD4+/CD8+ after treatment was significantly different and higher in the treatment group than in the control group, and the comparison was statistically significant (P < 0.05). The complication of the two groups showed that the rash, cough and sputum, elevated platelets, and gastrointestinal reactions in the treatment group were significantly lower than those in the control group, and the differences were statistically significant by test (P < 0.05). CONCLUSION: The comparative study of IHS treated with arsphenamine combined with reduced glutathione is more effective.

GRP75-dependent mitochondria-ER contacts ensure cell survival during early mouse thymocyte development.

Mitochondria and endoplasmic reticulum contacts (MERCs) control multiple cellular processes, including cell survival and differentiation. Based on the observations that MERCs were specifically enriched in the CD4-CD8- double-negative (DN) stage, we studied their role in early mouse thymocyte development. We found that T cell-specific knockout of Hspa9, which encodes GRP75, a protein that mediates MERC formation by assembling the IP3R-GRP75-VDAC complex, impaired DN3 thymocyte viability and resulted in thymocyte developmental arrest at the DN3-DN4 transition. Mechanistically, GRP75 deficiency induced mitochondrial stress, releasing mitochondrial DNA (mtDNA) into the cytosol and triggering the type I interferon (IFN-I) response. The IFN-I pathway contributed to both the impairment of cell survival and DN3-DN4 transition blockage, while increased lipid peroxidation (LPO) played a major role downstream of IFN-I. Thus, our study identifies the essential role of GRP75-dependent MERCs in early thymocyte development and the governing facts of cell survival and differentiation in the DN stage.

[Retracted] Mammalian STE20­like kinase 1 regulates pancreatic cancer cell survival and migration through Mfn2­mediated mitophagy.

Following the publication of this paper, it was drawn to the Editors' attention by a concerned reader that certain of the JC­1 staining images in Fig. 2C were strikingly similar to data appearing in different form in other articles written by different authors at different research institutes that had either already been published elsewhere prior to the submission of this paper to Molecular Medicine Reports, or were under consideration for publication at around the same time (a small number of which have been retracted). In addition, the Snail western blot data in Fig. 3E bore a close similarity to certain of the Mfn2 data shown in Fig. 4A. In view of the fact that certain of the contentious data had already apparently been published previously, and owing to a lack of confidence in the presentation of certain of the data in this paper, the Editor of Molecular Medicine Reports has decided that this paper should be retracted from the Journal. The authors were asked for an explanation to account for these concerns, but the Editorial Office did not receive a reply. The Editor apologizes to the readership for any inconvenience caused.

SWI/SNF chromatin remodeling factor BAF60b restrains inflammatory diseases by affecting regulatory T cell migration.

Regulatory T (Treg) cells play a critical regulatory role in the immune system by suppressing excessive immune responses and maintaining immune balance. The effective migration of Treg cells is crucial for controlling the development and progression of inflammatory diseases. However, the mechanisms responsible for directing Treg cells into the inflammatory tissue remain incompletely elucidated. In this study, we identified BAF60b, a subunit of switch/sucrose nonfermentable (SWI/SNF) chromatin remodeling complexes, as a positive regulator of Treg cell migration that inhibits the progression of inflammation in experimental autoimmune encephalomyelitis (EAE) and colitis animal models. Mechanistically, transcriptome and genome-wide chromatin-landscaped analyses demonstrated that BAF60b interacts with the transcription factor RUNX1 to promote the expression of CCR9 on Treg cells, which in turn affects their ability to migrate to inflammatory tissues. Our work provides insights into the essential role of BAF60b in regulating Treg cell migration and its impact on inflammatory diseases.

Association between serum galectin-3 and chronic obstructive pulmonary disease: A meta-analysis.

Chronic obstructive pulmonary disease (COPD) is a significant public health issue characterized by progressive and irreversible airflow limitation. The aim of this meta-analysis was to determine the association between changes in serum galectin-3 levels and COPD and to assess the relationship between serum galectin-3 levels and acute exacerbations of COPD (AECOPD). Relevant observational studies were retrieved from electronic databases, including PubMed, Web of Science, Embase, Wanfang, and China National Knowledge Infrastructure (CNKI). A random-effects model was used to combine the data, incorporating the influence of between-study heterogeneity. Twelve case-control studies were included. The pooled results showed a significantly higher serum level of galectin-3 in patients with COPD compared to controls (standardized mean difference [SMD] 0.60; 95% confidence interval [CI] 0.40 - 0.80; P < 0.001; I2 = 68%). Further meta-analysis suggested higher levels of serum galectin-3 in patients with AECOPD compared to those with stable COPD (SMD 0.33; 95% CI 0.20 - 0.46; P < 0.001; I2 = 0%). Subgroup analyses according to the mean age of the participants, the proportion of males, and study quality scores did not significantly change the results (P for subgroup differences all > 0.05). In conclusion, patients with COPD were found to have higher serum levels of galectin-3, with levels further elevated in patients with AECOPD compared to those with stable COPD.

Role of social support in the relationship between resilience and sleep quality among cancer patients.

Introduction: The present study aimed to investigate the effect of resilience on sleep quality and explore the role of social support between resilience and sleep quality in cancer patients. Methods: A multicenter and cross-sectional study was conducted in China from May to November 2021. A total of 202 cancer patients were recruited to complete the questionnaires composed of demographic information, Pittsburg Sleep Quality Index (PSQI), Resilience Scale-14 (RS-14), and Multidimensions Scale of Perceived Social Support (MSPSS). The associations between resilience, social support, and sleep quality were explored through hierarchical regression analysis. Results: The prevalence of poor sleep quality was 50% among cancer patients. Resilience, social support, and the interaction between resilience and social support were all found to be significantly associated with sleep quality. Results of simple slope analysis indicated that the association between resilience and sleep quality were gradually decreased with the increasing social support levels (1 SD below the mean, B=-0.225, ß=-0.551, P<0.001), mean social support (B=-0.147, ß=-0.353, P<0.001) and high social support (1 SD above the mean, B=-0.065, ß=-0.156, P<0.001). Additionally, social support mediated the effect of resilience on sleep quality among cancer patients. Discussion: Poor sleep quality has been common in cancer patients. Social support could mediate and alleviate the relationship between resilience and sleep quality among cancer patients. Besides providing sufficient social support, interventions based on resilience should be applied to address sleep problems in cancer patients.

YiQi GuBen capsule alleviates OVA-induced asthma through improving mitochondrial dysfunction.

Objective: This study aims to explore the effect of YiQi GuBen capsule on improving mitochondrial dysfunction in an animal model of asthma.Methods: The mice (n = 8) were divided into four groups including control (NC), ovalbumin (OVA), dexamethasone (OVA + DEX), and YiQi GuBen (OVA + YQGB) groups. Firstly, we established an OVA-induced mouse asthma model except for the NC group, which then were treated with dexamethasone and YiQi GuBen capsule. Subsequently, HE staining and Masson staining were used for pathological analysis of mice lung tissues. Next, we used transmission electron microscopy (TEM) to observe the effect of the Yiqi Guben capsule on the ultrastructure of mitochondria. Flow cytometry was used to analyze the ROS level, membrane potential, and the number of mitochondria in lung tissue. Moreover, we analyzed the copy number of mitochondrial DNA (mtDNA) and the expression levels of activator peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) and mitochondrial transcription factor A (TFAM).Results: The results of the pathological analysis showed that after treatment with the YiQi GuBen capsule, the lung tissue damage was significantly reduced. In addition, we observed that the ultrastructural damage of mitochondria was improved. Flow cytometry proved that after treatment with the YiQi GuBen capsule, the level of ROS in the mitochondria was effectively reduced, while the mitochondrial membrane potential decreased and the number increased significantly. Moreover, we found that the copy number of mtDNA was significantly increased and the expression levels of PGC-1α and TFAM were significantly upgraded.Conclusion: This study suggests YiQi GuBen capsule can effectively improve mitochondrial dysfunction in the OVA-induced mouse model.

Pediatric massage therapy for treatment of tic disorders in children: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Tic disorder is a common neurodevelopmental disorder in childhood, characterized primarily by motor or vocal tics. However, there is no systematic evaluation of pediatric massage therapy for children with Tic disorder. This study aims to evaluate the effectiveness and safety of massage therapy for children with tic disorder through a comprehensive meta-analysis and systematic review. METHODS: We systematically searched relevant randomized controlled trials from various databases such as CBM, CNKI, VIP, Wanfang database, PubMed, Embase, Web of Science, Cochrane Library, and SINOMED, published up to October 2023. To collect randomized controlled trials on pediatric massage therapy or in combination with other therapies for the treatment of tic disorders in children. The risk of bias in the included articles was assessed using the Cochrane guideline. Meta-analyses were performed using Review Manager 5.4, and publication bias was evaluated by using Begg test and Egger test in Stata SE software. RESULTS: This meta-analysis included 19 randomized controlled trials with 1423 patients. Pediatric massage therapy alone or in combination with conventional medication demonstrated a significant increase in clinical effectiveness rates [risk ratios = 1.15, 95% confidence interval [CI] (1.10, 1.20), Z = 6.54, P < .001], and reduced Yale Global Tie Severity Scale scores [standardized mean difference = -0.85, 95% CI (-1.50, -0.19), Z = 2.54, P = .01] and traditional Chinese medicine syndrome scores [standardized mean difference = -1.35, 95%CI (-2.08, -0.63), Z = 3.66, P = .0002]. In terms of adverse reactions, there was no statistical difference between the experimental and control groups [risk ratios = 0.26, 95% CI (0.14, 0.49), Z = 4.25, P < .001]. The Begg test and Egger test results indicated no publication bias. CONCLUSION: Evidence suggests that pediatric massage therapy is effective in improving tic disorders in children.

Effects of physical and psychological symptoms on cancer-related fatigue among esophageal cancer patients.

BACKGROUND: Cancer-related fatigue (CRF) is considered one of the most prevalent and distressing symptoms among cancer patients and may vary among patients with different cancer types. However, few studies have explored the influence of physical and psychological symptoms on CRF among esophageal cancer (EC) patients without esophagectomy. Therefore, this study aimed to examine the effects of physical and psychological symptoms on CRF among EC patients without esophagectomy. METHODS: In the present study, a cross-sectional study was conducted from February 2021 to March 2022 in Liaoning Province, China. Among the 112 included participants, 97 completed our investigation. The questionnaires used consisted of the Brief Fatigue Inventory (BFI), the MD Anderson Symptom Inventory Gastrointestinal Cancer Module (MDASI-GI), the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7), and demographic and clinical information. Multivariate linear regression was conducted to test the relationships between physical and psychological symptoms and CRF. RESULTS: Of the 97 EC patients, 60.8% reported CRF (BFI ≥ 4). The mean age of the participants was 64.92 years (SD = 8.67). According to the regression model, all the variables explained 74.5% of the variance in CRF. Regression analysis indicated that physical symptoms, including constipation, diarrhoea, and difficulty swallowing, contributed to CRF. On the other hand, depressive symptoms increased the level of CRF among EC patients without esophagectomy. CONCLUSIONS: Given the high prevalence of CRF among EC patients without esophagectomy, it is urgent to emphasize the importance of fatigue management interventions based on physical and psychological symptoms to alleviate CRF in EC patients.

Immunological pathways in viral hepatitis-induced hepato-cellular carcinoma. / è‚ç‚Žç— æ¯’æ„ŸæŸ“å¯¼è‡´è‚ç»†èƒžç™Œå‘ç”Ÿçš„å ç–«æœºåˆ¶ç ”ç©¶è¿›å±•.

Hepatocellular carcinoma (HCC) is a serious neoplastic disease with increasing incidence and mortality, accounting for 90% of all liver cancers. Hepatitis viruses are the major causative agents in the development of HCC. Hepatitis A virus (HAV) primarily causes acute infections, which is associated with HCC to a certain extent, as shown by clinicopathological studies. Chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infections lead to persistent liver inflammation and cirrhosis, disrupt multiple pathways associated with cellular apoptosis and proliferation, and are the most common viral precursors of HCC. Mutations in the HBV X protein (HBx) gene are closely associated with the incidence of HCC, while the expression of HCV core proteins contributes to hepatocellular lipid accumulation, thereby promoting tumorigenesis. In the clinical setting, hepatitis D virus (HDV) frequently co-infects with HBV, increasing the risk of chronic hepatitis. Hepatitis E virus (HEV) usually causes acute infections. However, chronic infections of HEV have been increasing recently, particularly in immuno-compromised patients and organ transplant recipients, which may increase the risk of progression to cirrhosis and the occurrence of HCC. Early detection, effective intervention and vaccination against these viruses may significantly reduce the incidence of liver cancer, while mechanistic insights into the interplay between hepatitis viruses and HCC may facilitate the development of more effective intervention strategies. This article provides a comprehensive overview of hepatitis viruses and reviews recent advances in research on aberrant hepatic immune responses and the pathogenesis of HCC due to viral infection.
