IL13RA2 promotes progression of infantile haemangioma by activating glycolysis and the Wnt/β-catenin signaling pathway

Background:Interleukin 13 receptor subunit alpha 2(IL13RA2)plays an essential role in the progression of many cancers.However,the role of IL13RA2 in infantile haemangioma(IH)is still unknown.Materials and Methods:IL13RA2 expression in IH tissues was analyzed using western blot,qRT-PCR,and immunofluorescence.The role of IL13RA2 in haemangioma-derived endothelial cells(HemECs)was determined following knockdown or overexpression of IL13RA2 using CCK-8,colony formation,apoptosis,wound healing,tubule formation,Transwell,and western blot.Results:IL13RA2 expression was upregulated in IH tissues.IL13RA2 overexpression promoted proliferation,migration,and invasion of HemECs and induced glycolysis,which was confirmed with a glycolysis inhibitor.Specifically,IL13RA2 interacted withβ-catenin and activated the Wnt/β-catenin pathway in HemECs,which were involved in the above-mentioned effects of IL13RA2.Conclusions:These findings revealed that targeting IL13RA2 is a potential therapeutic approach for IH.

A biomimetic spore nanoplatform for boosting chemodynamic therapy and bacteria-mediated antitumor immunity for synergistic cancer treatment

Bacterial-based antitumor immunity has become a promising strategy to activate the immune system for fighting cancer.However,the potential application of bacterial therapy is hindered by the presence of instability and susceptibility to infections within bacterial populations.Furthermore,monotherapy is ineffective in completely eliminating complex cancer with multiple contributing factors.In this study,based on our discovery that spore shell(SS)of Bacillus coagulans exhibits excellent tumor-targeting ability and adjuvant activity,we develop a biomimetic spore nanoplatform to boost bacteria-mediated antitumor therapy,chemodynamic therapy and antitumor immunity for synergistic cancer treatment.In detail,SS is separated from probiotic spores and then attached to the surface of liposome(Lipo)that was loaded with hemoglobin(Hb),glucose oxidase(GOx)and JQ1to construct SS@Lipo/Hb/GOx/JQ1.In tumor tissue,highly toxic hydroxyl radicals(·OH)are generated via sequential catalytic reactions:GOx catalyzing glucose into H_(2)O_(2)and Fe^(2+)in Hb decomposing H_(2)O_(2)into·OH.The combination of·OH and SS adjuvant can improve tumor immunogenicity and activate immune system.Meanwhile,JQ1-mediated down-regulation of PD-L1 and Hb-induced hypoxia alleviation synergistically reshape immunosuppressive tumor microenvironment and potentiate immune response.In this manner,SS@Lipo/Hb/GOx/JQ1 significantly suppresses tumor growth and metastasis.To summarize,the nanoplatform represents an optimum strategy to potentiate bacteria-based cancer immunotherapy.

Characteristics and Influencing Factors of Self- Advocacy in Young and Middle-Aged Patients with Breast Cancer: A Latent Profile Analysis

Objective:To explore the potential categories and influencing factors of self-advocacy in young and middle-aged patients with breast cancer and to provide a theoretical basis for personalized intervention.Methods:From September 2023 to March 2024,314 young and middle-aged breast cancer patients were studied.Female cancer patients were surveyed using the self-advocacy scale,social support rating scale,and chronic health literacy scale.Latent profile analysis was used to investigate the heterogeneity and influencing factors of self-advocacy.Results:Self-advocacy among young and middle-aged breast cancer patients were classified into two potential categories:low advocacy-lack of support(51.7%)and high advocacy-effective communication(48.3%).Binary logistic regression analysis indicated that educational level,per capita monthly income,social support,and health literacy were significant influencing factors of these categories(P<0.05).Conclusion:Self-advocacy in young and middle-aged breast cancer patients demonstrates categorical heterogeneity.Identifying self-advocacy characteristics and implementing targeted intervention strategies—focused on self-efficacy and improving health literacy—can enhance self-advocacy in these patients.

Advances in the management of acute liver failure

Acute liver failure(ALF)is an uncommon but dramatic clinical syndrome characterized by hepatic encephalopathy and a bleeding tendency due to abrupt loss of liver function caused by massive or submassive liver necrosis in a patient with a previously healthy liver.The causes of ALF encompass a wide variety of toxic,viral,metabolic,vascular and autoimmune insults to the liver,and identifying the correct cause can be difficult or even impossible.Many patients with ALF develop a cascade of serious complications involving almost every organ system,and death is mostly due to multi-organ failure,hemorrhage,infection,and intracranial hypertension.Fortunately,the outcome of ALF has been improved in the last 3 decades through the specific treatment for the disease of certain etiology,and the advanced intensive care management.For most severely affected patients who fail to recover after treatment,rapid evaluation for transfer to a transplantation center and consideration for liver transplantation is mandatory so that transplantation can be applied before contraindications develop.This review focuses on the recent advances in the understanding of various contributing etiologies,the administration of etiology-specific treatment to alleviate the liver injury,and the management of complications(e.g.,encephalopathy,coagulopathy,cardiovascular instability,respiratory failure,renal failure,sepsis and metabolic disturbance)in patients with ALF.Assessment of the need for liver transplantation is also presented.

Small bowel racemose hemangioma complicated with obstruction and chronic anemia:A case report and review of literature

BACKGROUND Gastrointestinal hemangiomas are rare benign tumors.According to the size of the affected vessels,hemangiomas are histologically classified into cavernous,capillary,or mixed-type tumors,with the cavernous type being the most common and racemose hemangiomas being very rare in the clinic.Melena of uncertain origin and anemia are the main clinical manifestations,and other presentations are rare.Due to the rarity of gastrointestinal hemangiomas and lack of specific manifestations and diagnostic methods,preoperative diagnoses are often delayed or incorrect.CASE SUMMARY We report a 5-year-old girl who presented with abdominal pain,nausea,and vomiting for a duration of 10 h.The laboratory studies showed prominent anemia.Computed tomography and contrast-enhanced computed tomography of the abdomen revealed a small bowel obstruction caused by a giant abdominal mass.Segmental resection of the ileal lesions was performed through surgery,and the final pathology results revealed a diagnosis of racemose hemangioma complicated by a small bowel obstruction and simultaneous chronic anemia.CONCLUSION The current report will increase the understanding of the diagnosis and treatment of gastrointestinal hemangiomas and provide a review of the related literature.

Surgical treatment for residual or recurrent strabismus

Although the surgical treatment is a relatively effective and predictable method for correcting residual or recurrent strabismus, such as posterior fixation sutures,medial rectus marginal myotomy, unilateral or bilateral rectus re-recession and resection, unilateral lateral rectus recession and adjustable suture, no standard protocol is established for the surgical style. Different surgical approaches have been recommended for correcting residual or recurrent strabismus. The choice of the surgical procedure depends on the former operation pattern and the surgical dosages applied on the patients, residual or recurrent angle of deviation and the operator’s preference and experience. This review attempts to outline recent publications and current opinion in the management of residual or recurrent esotropia and exotropia.

Clinical and experimental study on angiopoietin-like protein 8 associated with proliferative diabetic retinopathy

AIM：To confirm the role of angiopoietin-like protein 8（Angptl 8） in proliferative diabetic retinopathy（PDR）.METHODS：The sera and aqueous humor of 10 PDR patients and 10 non-diabetic retinopathy（NDR） patients（idiopathic macular hole patients） were collected and the expression of Angptl 8 was detected by enzyme linked immune-sorbent assay（ELISA）.Experimental diabetes mice model was induced with streptozotocin.The expression of glycosylated hemoglobin and Angptl 8 in sera was detected.Recombinant Angptl 8 was re-infused into wild type（WT） diabetic mice and spatial frequency threshold and contrast sensitivity were measured.In vitro retinal pigment epithelium（RPE） were stimulated by recombinant Angptl 8 for 24 h.MMT assay were used to detect cell proliferation.At the same time,q RT-PCR and Western blot was used to measure the expression of proliferation-related factors in PRE cells.RESULTS：The expression of Angptl 8 was markedly increased in the sera and aqueous humor of PDR patients（F=99.02,P〈0.0001 in sera;t=10.42,P〈0.0001 in aqueous）.After successfully establishing the diabetic mice model,we found that glycosylated hemoglobin and Angptl 8 expression levels were increased.Re-infusion of recombinant Angptl 8 into WT diabetic mice could further decrease spatial frequency threshold and contrast sensitivity（P〈0.01）.In vitro,RPE cells stimulated by recombinant Angptl 8could increase the relative absorbance of MMT assay（1.486±0.042 vs 1.000±0.104,P〈0.05） and proliferating cell nuclear antigen（PCNA） expression（0.55±0.01 vs 0.29±0.03,P〈0.05）.The proliferative effect of Angptl 8 is mainly mediated by increasing the expression of proliferation-activating factors cyclin A1（4.973±0.205 vs 2.720±0.197,P〈0.05）,cyclin F（5.690±0.219 vs 4.297±0.292,P〈0.05） and E2 F2（2.297±0.102 vs 1.750±0.146,P〈0.05）,and reducing the expression of proliferation-inhibiting factors cdkn1（2.370±0.074 vs 3.317±0.135,P〈0.05） and cdkn2（4.793±0.065 vs 5.387±0.149,P〈0.05）.CONCLUSION：The expression of Angptl 8 is increased in PDR,and the increased Angptl 8 can promote proliferation and increase proliferation-related factors.

Quantitative and morphological differences of nerve fibers between proliferative and mature scars in two-and three-dimensional spaces

BACKGROUND： Numerous studies use fluorescent microscopy to obtain two-dimensional optical images of the morphology of nerve fibers in hypertrophic scars. In addition, current confocal microscopy studies have focused on normal, not pathological, cutaneous nerves. However, laser scanning confocal microscopy results in a three-dimensional structure of the nerve fibers. OBJECTIVE： To observe quantitative and morphological differences in nerve fibers from the proliferative and mature stage in hypertrophic scars using fluorescent and confocal microscopy. DESIGN, TIME AND SETTING： Neuropathological, comparison study was conducted at the Provincial Hospital Affiliated to Shandong University, China from June 2006 to July 2007. PARTICIPANTS： Specimens were selected from 30 patients undergoing scar restoration at the Provincial Hospital Affiliated to Shandong University of China at 1 month to 23 years following wound healing. The study comprised 20 males and 10 females. The scars were fibrous lesions, erythematous, tough, confined to skin lesions, did not exhibit ulceration or infection, exhibited telangiectasia, with or without itching and pain, and were not locally treated. Samples were equally assigned to two groups according to course of disease： proliferative group （〈 6 months） and mature group （6-24 months）. Control samples were collected from full-thickness skin from donor sites （n = 10）. METHODS： Nerve fiber morphology was observed using fluorescent and confocal microscopy following immunofluorescence of the skin specimens. The microscopic images were semi-quantitatively analyzed to acquire a positive area ratio of neurofilament protein-positive nerve fibers. MAIN OUTCOME MEASURES： Morphology and positive area ratio of neurofilament protein/positive nerve fibers was measured. RESULTS： The positive area ratio of neurofilament protein-positive nerve fibers was significantly greater in the proliferative group compared to the normal control group （P 〈 0.05）. Nerve fibers were irregularly distributed and exhibited local swelling, twisting, and disconnection. However, the positive area ratio of neurofilament protein-positive nerve fibers was significantly less in the mature group compared with the normal control group （P 〈 0.05）. The nerve fibers were arranged in an orderly manner, with intact inner and stereoscopic structures similar to normal skin. CONCLUSION： Compared with mature scars, hypertrophic scars exhibited a greater number of nerve fibers, with more serious pathologies.

Remodeling of skin nerve fibers during burn wound healing

Burn wound healing involves a complex sequence of processes. Recent studies have revealed that skin reinnervation may have an impact on physiological wound repair. Few studies have addressed the process of reinnervation and morphological changes in regenerated nerve fibers. The regeneration of neurites during full-thickness burn wound healing was determined by immunofluorescent staining using an anti-neurofilament protein monoclonal antibody, and three-dimensional morphology was observed under a laser scanning confocal microscope. Morphology and the volume fraction of collagen and nerve fibers were measured. Skin reinnervation increased during wound healing, peaked during the proliferative scar stage, and then decreased to lower levels during the maturation period. The results from the skin nerve fibers correlated with those from collagen using semi-quantitative analysis. Disintegration and fragmentation were observed frequently in samples from the proliferative stage, and seldom occurred during the maturation stage. There was a remodeling process of regenerated nerve fibers during wound healing, which comprised changed innervation density and topical morphology. The mechanism of remodeling for nerve fibers requires further investigation.

Rapid,specific and sensitive detection of Vibrio vulnificus by loop-mediated isothermal amplification targeted to vvhA gene

Vibrio vulnificus is an estuarine bacterial pathogen for human.The rapid,specific and sensitive detection of V.vulnificus is urgently needed for early disease diagnosis and timely treatment of V.vulnificus infection.In the study,a loop-mediated isothermal amplification（LAMP） technique was developed for V.vulnificus detection with a set of primers,composed of two out primers and two inner primers targeted to vvh A gene.The optimal amplification temperature was 63°C and the reaction only took 35 min.The amplification products could not only be detected by agarose gel electrophoresis with ladder-like pattern bands,but also could be visualized using calcein with naked eye directly.Forty-five strains were tested for the specificity of LAMP assay,and all the V.vulnificus strains were identified correctly while other strains were negative results.The sensitive of the new LAMP assay was 100-fold more sensitive than the conventional PCR.Meanwhile,all the V.vulnificus strains were detected correctly in spiked,clinical and environmental samples by the new LAMP assay.Compared with other well-known techniques,the new LAMP assay targeted to vvh A gene was extremely rapid,simple,sensitive and specific for V.vulnificus identification.

Successful opening in-stent chronic total occlusion lesion of coronary artery by excimer laser coronary angioplasty

In percutaneous coronary intervention (PCI), chronic total occlusion (CTO) coronary artery disease still remains difficult to treat. One of the reasons for the failure is the hard of the CTO lesions that balloon is difficult to pass through or expand. Previous methods to deal with CTO lesions that cannot be passed by balloon, include selecting reinforced catheter (such as 5 in 6 guiding catheter, Guidzilla catheter, or Tornus microcatheter), guidewire extrusion or rotary grinding technology. In recent years, excimer laser coronary angioplasty (ELCA) has been gradually applied to CTO lesions. Using inert halide as the laser medium, ELCA emits a 308 nm high-intensity unidirectional light wave with absorption depth of only 50 μmL, resulting in less thermal effect and less damage to non-target lesions. In this paper, we will describe a successful PCI case of an in-stent CTO lesion using ELCA with long term coronary angiography follow-up.

Reabsorption of intervertebral disc prolapse after conservative treatment with traditional Chinese medicine:A case report

BACKGROUND Conservative treatments have been reported to diminish or resolve clinical symptoms of lumbar intervertebral disc herniation(LIDH)within a few weeks.CASE SUMMARY Computed tomography and magnetic resonance imaging(MRI)of the lumbar region of a 25-yearold male diagnosed with LIDH showed prolapse of the L5/S2 disc.The disc extended 1.0 cm beyond the vertebral edge and hung along the posterior vertebral edge.The patient elected a conservative treatment regimen that included traditional Chinese medicine(TCM),acupuncture,and massage.During a follow-up period of more than 12 mo,good improvement in pain was reported without complications.MRI of the lumbar region after 12 mo showed obvious reabsorption of the herniation.CONCLUSION A conservative treatment regimen of TCM,acupuncture,and massage promoted reabsorption of a prolapsed disc.

Recombinant angiopoietin-like protein 4 attenuates intestinal barrier structure and function injury after ischemia/reperfusion

BACKGROUND Intestinal barrier breakdown,a frequent complication of intestinal ischemiareperfusion(I/R)including dysfunction and the structure changes of the intestine,is characterized by a loss of tight junction and enhanced permeability of the intestinal barrier and increased mortality.To develop effective and novel therapeutics is important for the improvement of outcome of patients with intestinal barrier deterioration.Recombinant human angiopoietin-like protein 4(rhANGPTL4)is reported to protect the blood-brain barrier when administered exogenously,and endogenous ANGPTL4 deficiency deteriorates radiationinduced intestinal injury.AIM To identify whether rhANGPTL4 may protect intestinal barrier breakdown induced by I/R.METHODS Intestinal I/R injury was elicited through clamping the superior mesenteric artery for 60 min followed by 240 min reperfusion.Intestinal epithelial(Caco-2)cells and human umbilical vein endothelial cells were challenged by hypoxia/reoxygenation to mimic I/R in vitro.RESULTS Indicators including fluorescein isothiocyanate-conjugated dextran(4 kilodaltons;FD-4)clearance,ratio of phosphorylated myosin light chain/total myosin light chain,myosin light chain kinase and loss of zonula occludens-1,claudin-2 and VE-cadherin were significantly increased after intestinal I/R or cell hypoxia/reoxygenation.rhANGPTL4 treatment significantly reversed these indicators,which were associated with inhibiting the inflammatory and oxidative cascade,excessive activation of cellular autophagy and apoptosis and improvement of survival rate.Similar results were observed in vitro when cells were challenged by hypoxia/reoxygenation,whereas rhANGPTL4 reversed the indicators close to normal level in Caco-2 cells and human umbilical vein endothelial cells significantly.CONCLUSION rhANGPTL4 can function as a protective agent against intestinal injury induced by intestinal I/R and improve survival via maintenance of intestinal barrier structure and functions.

Common carotid artery thrombosis and malignant middle cerebral artery infarction following ovarian hyperstimulation syndrome:A case report

BACKGROUND Arterial thrombosis is a serious and rare complication of ovarian hyperstimulation syndrome(OHSS).Herein,we describe a case of OHSS complicated by common carotid artery thrombosis and malignant middle cerebral artery infarction after egg retrieval and before embryo transfer.CASE SUMMARY A 32-year-old female with a family history of thrombosis who was undergoing in vitro fertilization due to unexplained infertility,was admitted due to abdominal distension for 3 d and coma for 2 h.She received egg retrieval 7 d ago and embryo transfer had not yet been performed.Blood biochemical analysis showed estrogen of 15781 pmol/L.Gynecological examination showed palpable masses on both sides of the adnexal areas.Ultrasound observed enlarged ovaries and abdominal ascites.Imaging examination of the head and neck revealed fresh malignant middle cerebral artery infarction in the left side of brain and internal carotid artery as well as occlusion in the left carotid artery,internal carotid artery,and middle cerebral artery.The patient was finally diagnosed with severe OHSS,complicated by common carotid artery thrombosis and malignant middle cerebral artery infarction.Liquid replacement,anticoagulation,vascular endothelium protection,brain protection and decompressive craniectomy were carried out.Rehabilitation training was then performed for 6 mo.At present,she has poor speaking ability and decreased muscle strength on the right side.CONCLUSION There is a risk of thrombosis during any period of OHSS.During in vitro assisted reproduction,for cases with a family history of thrombosis,hyperlipidemia and other high-risk factors,serum lipid levels should be controlled as soon as possible to improve metabolic dysfunction.When thrombosis occurs,timely and effective treatment should be performed to improve the prognosis.

Changes and clinical significance of serum tumor markers in patients with rheumatoid arthritis combined with interstitial lung disease

Objective: To investigate the changes and clinical significance of serum tumor markers in patients with rheumatoid arthritis (RA) combined with interstitial lung disease. Methods:A total of 50 healthy volunteers were chosen as the normal control group, 47 patients with rheumatoid arthritis alone were chosen as the RA group, and 28 patients with rheumatoid arthritis combined with interstitial lung disease were chosen as combined disease group. The differences in the levels of serum tumor markers, RA markers and inflammatory mediators were compared among the three groups, and Pearson test was used to evaluate the correlation of serum tumor marker levels with RA markers and inflammatory mediators in patients with RA combined with interstitial lung disease. Results: Serum tumor markers CA199, CA153 and CEA levels of combined disease group were higher than those of RA group;RA markers RF and GPI levels were higher than those of RA group whereas CCP and AKA levels were not significantly different from those of RA group;inflammatory mediators HMGB1, GM-CSF, IL-6, IL-17 and IL-27 levels were higher than those of RA group. Correlation analysis showed that serum tumor markers CA199, CA153 and CEA levels in patients with RA combined with interstitial lung disease were positively correlated with RF, GPI, HMGB1, GM-CSF, IL-6, IL-17 and IL-27 levels. Conclusion: Serum tumor markers CA199, CA153 and CEA levels abnormally increase in patients with RA combined with interstitial lung disease, and the specific levels were directly correlated with the disease severity.
