Intermittent theta burst stimulation(iTBS),a time-saving and cost-effective repetitive transcranial magnetic stimulation regime,has been shown to improve cognition in patients with Alzheimer’s disease(AD).However,the specific mechanism underlying iTBS-induced cognitive enhancement remains unknown.Previous studies suggested that mitochondrial functions are modulated by magnetic stimulation.Here,we showed that iTBS upregulates the expression of iron-sulfur cluster assembly 1(ISCA1,an essential regulatory factor for mitochondrial respiration)in the brain of APP/PS1 mice.In vivo and in vitro studies revealed that iTBS modulates mitochondrial iron-sulfur cluster assembly to facilitate mitochondrial respiration and function,which is required for ISCA1.Moreover,iTBS rescues cognitive decline and attenuates AD-type pathologies in APP/PS1 mice.The present study uncovers a novel mechanism by which iTBS modulates mitochondrial respiration and function via ISCA1-mediated iron-sulfur cluster assembly to alleviate cognitive impairments and pathologies in AD.We provide the mechanistic target of iTBS that warrants its therapeutic potential for AD patients.

BACKGROUND Peripherally inserted central catheters(PICCs)are an essential infusion route for oncology patients receiving intravenous treatments,but lower extremity veni-puncture is the preferred technique for patients with superior vena cava syndrome(SVCS).We report the case of a patient with a lower extremity PICC ectopic to the ascending lumbar vein,to indicate and verify PICC catheterisation in the lower extremity is safe and feasible.And hope to provide different per-spectives for clinical PICC venipuncture to get the attention of peers.CASE SUMMARY On 24 August 2022,a 58-year-old male was admitted to our department due to an intermittent cough persisting for over a month,which worsened 10 d prior.Imaging and laboratory investigations suggested the patient with pulmonary malignancy and SVCS.Chemotherapy was not an absolute contraindication in this patient.Lower extremity venipuncture is the preferred technique because administering upper extremity venous transfusion to patients with SVCS can exacerbate oedema in the head,neck,and upper extremities.The patient and his family were informed about the procedure,and informed consent was obtained.After successful puncture and prompt treatment,the patient was discharged,experiencing some relief from symptoms.CONCLUSION Inferior vena cava catheterisation is rare and important for cancer patients with SVCS,particularly in complex situations involving ectopic placement.

Cell replacement therapy using neural progenitor cells(NPCs)has been shown to be an effective treatment for ischemic stroke.However,the therapeutic effect is unsatisfactory due to the imbalanced homeostasis of the local microenvironment after ischemia.Microenvironmental acidosis is a common imbalanced homeostasis in the penumbra and could activate acid-sensing ion channels 1a(ASIC1a),a subunit of proton-gated cation channels following ischemic stroke.However,the role of ASIC1a in NPCs post-ischemia remains elusive.Here,our results indicated that ASIC1a was expressed in NPCs with channel functionality,which could be activated by extracellular acidification.Further evidence revealed that ASIC1a activation inhibited NPC migration and neurogenesis through RhoA signaling-mediated reorganization of filopodia formation,which could be primarily reversed by pharmacological or genetic disruption of ASIC1a.In vivo data showed that the knockout of the ASIC1a gene facilitated NPC migration and neurogenesis in the penumbra to improve behavioral recovery after stroke.

BACKGROUND The efficacy and safety of transarterial chemoembolization(TACE)combined with lenvatinib plus programmed cell death protein-1(PD-1)for unresectable hepato-cellular carcinoma(HCC)have rarely been evaluated and it is unknown which factors are related to efficacy.AIM To evaluate the efficacy and independent predictive factors of TACE combined with lenvatinib plus PD-1 inhibitors for unresectable HCC.METHODS This study retrospectively enrolled patients with unresectable HCC who received TACE/lenvatinib/PD-1 treatment between March 2019 and April 2022.Overall survival(OS)and progression-free survival(PFS)were determined.The objective response rate(ORR)and disease control rate(DCR)were evaluated in accordance with the modified Response Evaluation Criteria in Solid Tumors.Additionally,the prognostic factors affecting the clinical outcome were assessed.RESULTS One hundred and two patients were enrolled with a median follow-up duration of 12.63 months.The median OS was 26.43 months(95%CI:17.00-35.87),and the median PFS was 10.07 months(95%CI:8.50-11.65).The ORR and DCR were 61.76%and 81.37%,respectively.The patients with Barcelona Clinic Liver Cancer Classification(BCLC)B stage,early neutrophil-to-lymphocyte ratio(NLR)response(decrease),or early alpha-fetoprotein(AFP)response(decrease>20%)had superior OS and PFS than their counterparts.CONCLUSION This study showed that TACE/lenvatinib/PD-1 treatment was well tolerated with encouraging efficacy in patients with unresectable HCC.The patients with BCLC B-stage disease with early NLR response(decrease)and early AFP response(decrease>20%)may achieve better clinical outcomes with this triple therapy.

BACKGROUND A fish spike stuck in the throat is a common ear,nose,and throat(ENT)emergency.However,it is very rare for a fish spike to reach the thyroid tissue through the throat,which is very dangerous and can lead to pharyngeal fistula,cervical abscess,mediastinal abscess,and thyroid abscess.Proper and timely management can help reduce complications,especially in elderly patients.CASE SUMMARY In the case presented here,the causative factor was dentures,but improper management aggravated the condition.In the case presented here,an elderly woman with a history of accidentally swallowing fish bones for 20 d had a sensation of foreign bodies in her throat.Eventually,computed tomography(CT)of the neck showed that the left side of the thyroid gland had a dense shadow in the form of a stripe.CONCLUSION If a fishbone foreign body is not visible during endoscopic examination but the patient has significant symptoms,the surgeon should be aware that the fishbone may be lodged in the thyroid.To avoid a misdiagnosis,ultrasound,CT,and other tests can be used to clarify the diagnosis.T The first step in treating a fish bone in the thyroid gland is to determine the position of the foreign body and the extent of the infection,and to develop a personalized surgical plan for its removal.At the same time,scientific information should be made available to the general public so that people know that if a fish bone is accidentally lodged,they should not force it to be swallowed or be spit out by inducing vomiting,which are incorrect methods and may aggravate the condition or even cause it to migrate outside the cavity,leading to serious complications,as in this reported case.

Intratumoral microbiota has become research hotspots,and emerges as a non-negligent new component of tumor microenvironments(TME),due to its powerful infuence on tumor initiation,metas-tasis,immunosurveillance and prognosis despite in low-biomass.The accumulations of microbes,and their related components and metabolites within tumor tissues,endow TME with additional pluralistic features which are distinct from the conventional one.Therefore,it's definitely necessary to comprehen-sively delineate the sophisticated landscapes of tumor microbe microenvironment,as well as their func-tions and related underlying mechanisms.Herein,in this review,we focused on the fields of tumor microbe microenvironment,including the heterogeneity of intratumor microbiota in different types of tu-mors,the controversial roles of intratumoral microbiota,the basic features of tumor microbe microenvi-ronment(i.e.,pathogen-associated molecular patterns(PAMPs),typical microbial metabolites,autophagy,infammation,multi-faceted immunomodulation and chemoresistance),as well as the multi-disciplinary approach-based intervention of tumor microbiome for cancer therapy by applying wild-type or engineered live microbes,microbiota metabolites,antibiotics,synthetic biology and rationally de-signed biomaterials.We hope our work will provide valuable insight to deeply understand the interplay of cancer-immune-microbial,and facilitate the development of microbes-based tumor-specific treatments.

Atherosclerotic cardiovascular disease and its complications are a high-incidence disease worldwide.Numerous studies have shown that blood flow shear has a huge impact on the function of vascular endothelial cells,and it plays an important role in gene regulation of pro-inflammatory,pro-thrombotic,pro-oxidative stress,and cell permeability.Many impor-tant endothelial cell mechanosensitive genes have been discovered,including KLK10,CCN gene family,NRP2,YAP,TAZ,HIF-1α,NF-kB,FOS,JUN,TFEB,KLF2/KLF4,NRF2,and ID1.Some of them have been intensively studied,whereas the relevant regulatory mechanism of other genes remains unclear.Focusing on these mechanosensitive genes will provide new strategies for therapeutic intervention in atherosclerotic vascular disease.Thus,this article reviews the mechanosensitive genes affecting vascular endothelial cells,including classical pathways and some newly screened genes,and summarizes the latest research progress on their roles in the pathogenesis of atherosclerosis to reveal effective therapeutic targets of drugs and provide new insights foranti-atherosclerosis.

Objective This study aimed to comprehensively analyze and compare the clinicopathological features and prognosis of Chinese patients with human epidermal growth factor receptor 2(HER2)-low early breast cancer(BC)and HER2-IHC0 BC.Methods Patients diagnosed with HER2-negative BC(N=999)at our institution between January2011 and December 2015 formed our study population.Clinicopathological characteristics,association between estrogen receptor(ER)expression and HER2-low,and evolution of HER2 immunohistochemical(IHC)score were assessed.Kaplan-Meier method and log-rank test were used to compare the long-term survival outcomes(5-year follow-up)between the HER2-IHC0 and HER2-low groups.Results HER2-low BC group tended to demonstrate high expression of ER and more progesterone receptor(PgR)positivity than HER2-IHC0 BC group(P<0.001).The rate of HER2-low status increased with increasing ER expression levels(Mantel-Haenszelχ^(2)test,P<0.001,Pearson’s R=0.159,P<0.001).Survival analysis revealed a significantly longer overall survival(OS)in HER2-low BC group than in HER2-IHC0 group(P=0.007)in the whole cohort and the hormone receptor(HR)-negative group.There were no significant differences between the two groups in terms of disease-free survival(DFS).The discordance rate of HER2 IHC scores between primary and metastatic sites was 36.84%.Conclusion HER2-low BC may not be regarded as a unique BC group in this population-based study due to similar clinicopathological features and prognostic roles.

Purpose:To identify the risk factors for training-related lower extremity muscle injuries in young males by a non-invasive method of body composition analysis.Methods:A total of 282 healthy young male volunteers aged 18-20 years participated in this cohort study.Injury location,degree,and injury rate were adjusted by a questionnaire based on the overuse injury assessment methods used in epidemiological studies of sports injuries.The occurrence of training injuries is monitored and diagnosed by physicians and treated accordingly.The body composition was measured using the BodyStat QuadScan 4000 multifrequency Bio-impedance system at 5,50,100 and 200 kHz to obtain 4 impedance values.The Shapiro-Wilk test was used to check whether the data conformed to a normal distribution.Data of normal distribution were shown as mean±SD and analyzed by t-test,while those of non-normal distribution were shown as median(Q1,Q3)and analyzed by Wilcoxon rank sum test.The receiver operator characteristic curve and logistic regression analysis were performed to investigate risk factors for developing training-related lower extremity injuries and accuracy.Results:Among the 282 subjects,78(27.7%)developed training injuries.Lower extremity training injuries revealed the highest incidence,accounting for 23.4%(66 cases).These patients showed higher percentages of lean body mass(p=0.001),total body water(TBW,p=0.006),extracellular water(p=0.020)and intracellular water(p=0.010)as well as a larger ratio of basal metabolic rate/total weight(p=0.006),compared with those without lower extremity muscle injuries.On the contrary,the percentage of body fat(p=0.001)and body fat mass index(p=0.002)were lower.Logistic regression analysis showed that TBW percentage>65.35%(p=0.050,odds ratio=3.114)and 3rd space water>0.95%(p=0.045,odds ratio=2.342)were independent risk factors for lower extremity muscle injuries.Conclusion:TBW percentage and 3rd space water measured with bio-impedance method are potential risk factors for predicting the incidence of lower

Background Hematoma expansion is a determinant of poor outcome of intracerebral hemorrhage but occurs frequently,especially in warfarin-associated intracerebral hemorrhage(W-ICH).In the present study,we employ the warfarin-associated intracerebral hemorrhage(W-ICH)rat model,to explore the efficacy and potential mechanism of glibenclamide pretreatment on hematoma expansion after intracerebral hemorrhage,hoping to provide proof of concept that glibenclamide in stroke primary and secondary prevention is also potentially beneficial for intracerebral hemorrhage patients at early stage.Methods In the present study,we tested whether glibenclamide,a common hypoglycemic drug,could attenuate hematoma expansion in a rat model of W-ICH.Hematoma expansion was evaluated using magnetic resonance imaging;brain injury was evaluated by brain edema and neuronal death;and functional outcome was evaluated by neurological scores.Then blood-brain barrier integrity was assessed using Evans blue extravasation and tight junction-related protein.Results The data indicated that glibenclamide pretreatment significantly attenuated hematoma expansion at 24 h after W-ICH,thus mitigating brain edema and neuronal death and promoting neurological function recovery,which may benefit from alleviating blood-brain barrier disruption by suppressing matrix metallopeptidase-9.Conclusions The results indicate that glibenclamide pretreatment in stroke primary and secondary prevention might be a promising therapy for hematoma expansion at the early stage of W-ICH.
