BACKGROUND Ischemic colitis(IC)is also known as colon ischemia and is caused by colon vascular occlusion or nonocclusion,which results in a reduced blood supply to the colon and is not significant enough to maintain the metabolic function of cells,leading to intestinal wall ischemia.Its main symptoms include abdominal pain,diarrhea,and bloody stool.In severe cases,intestinal gangrene,peritonitis,intestinal stenosis and even intestinal obstruction may occur.IC induced by long-term use of certain special drugs is relatively rare in clinical practice.This article describes the clinical diagnosis and treatment of a typical case and provides a new treatment idea for the treatment of IC.CASE SUMMARY The patient was admitted to the hospital with"abdominal pain for half a month and bloody stool with mucous and pus for 3 d"and was diagnosed with"IC".Symptomatic and supportive treatment,such as antibiotics(levofloxacin),acid inhibition and stomach protection,fluid replenishment,and intravenous nutrition,was given.The patient's colonic ulcers were considered to be related to the oral administration of platelet(PLT)-raising capsules;the patient was asked to stop PLT-raising drugs for selective review via colonoscopy,and antibiotics and mesalazine enteric-coated tablets were stopped.Under the guidance of hematology consultation,60 mg of methylprednisolone was given in combination with PLT infusion to increase the PLT.After treatment,the patient's condition stabilized,the patient’s stool turned yellow,the patient’s symptoms improved,and the patient was allowed to leave the hospital.CONCLUSION PLT-raising capsules can lead to IC,so clinicians should have a full understanding of the application of these drugs in the treatment of various causes of thrombocyt-INTRODUCTION Ischemic colitis(IC)is also known as colon ischemia(CI)and is caused by colon vascular occlusion or nonocclusion,which results in a reduced blood supply to the colon;this process is not significant enough to maintain the metabolic function of cells,leading to int

This research aims to identify the key fatty acid beta-oxidation(FAO)genes that are altered in kidney renal clear cell carcinoma(KIRC)and to analyze the role of these genes in KIRC The Gene Expression Omnibus(GEO)and FAO datasets were used to identify these key genes.Wilcoxon rank sum test was used to assess the levels of acyl-CoA dehydrogenase medium chain(ACADM)between KIRC and non cancer samples.The logistic regression and Wilcoxon rank sum test were used to explore the association between ACADM and clinical features.The diagnostic performance of ACADM for KIRC was asessed using a diagnostic receiver operating ch aracteristic(ROC)curve.The co-expressed genes of ACADM were identifed in LinkedOmics database,and their function and pathway enrichment were analyzed.The correlation between ACADM expression level and immune infitration was analyzed by Gene Set Variation Analysis(GSVA)method Additionally,the proliferation,migration,and invasion abilities of KIRC cells were assessed after overexpressing ACADM.Following differential analysis and intersection,we identifed six hub genes,induding ACADM.We found that the expression level of ACADM was decreased in KIRC tissues and had a better diagnostic efect(AUC=0.916).Survival analysis suggested that patients with decreased ACADM expression had a worse prognosis.According to correlation analysis,a variety of dinical features were associated with the expression level of ACADML By analyzing the infiltration level of immune cells,we found that ACADM may be related to the enrichment of immune cells.Finally,ACADM overexpression inhibited proliferation,migration,and invasion of KIRC cells.In conclusion,our findings suggest that reduced ACADM expression in KIRC patients is indicative of poor prognosis.These results imply that ACADM may be a diagnostic and prognostic marker for individuals with KIRC,offering a reference for dinicians in diagnosis and treatment.

Diferent from necrosis,apoptosis,autophagy and other forms of cell death,ferroptosis is a mechanism that catalyzes lipid peroxidation of polyunsaturated ftty acids under the action of iron divalent or lipoxygenase,leading to cell death.Apatinib is currently used in the third line standard treatment of advanced gastric cancer,targeting the anti-angiogenesis pathway.However,Apatinib mediated ferroptosis in vascular endothelial cells has not been reported yet.Tumor.secreted exosomes can be taken up into target cells to regulate tumor development,but the mechanism related to vascular endothelial cell ferroptosis has not yet been discovered.Here,we show that exosomes secreted by gastric cancer cells carry miR-214.3p into vascular endothelial cells and directdy target zinc finger protein A20 to negatively regulate ACSL4,a key enzyme of lipid peroxidation during frroptosis thereby inhibiting ferroptosis in vascular endothelial cells and reducing the eficiency of Apatinib.In conclusion,inhibition of miR-214-3p can increase the sensitivity of vascular endothelial cells to Apatinib,thereby promoting the antiangiogenic efect of Apatinib,suggesting a potential combination therapy for advanced gastric cancer.

Colorectal cancer(CRC)belongs to the class of significantly malignant tumors found in humans.Recently,dysregulated fatty acid metabolism(FAM)has been a topic of attention due to its modulation in cancer,specifically CRC.However,the regulatory FAM pathways in CRC require comprehensive elucidation.Methods:The clinical and gene expression data of 175 fatty acid metabolic genes(FAMGs)linked with colon adenocarcinoma(COAD)and normal cornerstone genes were gathered through The cancer Genome Atlas(TCGA)-COAD corroborating with the Molecular Signature Database v7.2(MSigDB).Initially,crucial prognostic genes were selected by uni-and multi-variate Cox proportional regression analyses;then,depending upon these identified signature genes and clinical variables,a nomogram was generated.Lastly,to assess tumor immune characteristics,concomitant evaluation of tumor immune evasion/risk scoring were elucidated.Results:A 8-gene signature,including ACBD4,ACOX1,CD36,CPT2,ELOVL3,ELOVL6,ENO3,and SUCLG2,was generated,and depending upon this,CRC patients were categorized within high-risk(H-R)and low-risk(L-R)cohorts.Furthermore,risk and age-based nomograms indicated moderate discrimination and good calibration.The data confirmed that the 8-gene model efficiently predicted CRC patients’prognosis.Moreover,according to the conjoint analysis of tumor immune evasion and the risk scorings,the H-R cohort had an immunosuppressive tumor microenvironment,which caused a substandard prognosis.Conclusion:This investigation established a FAMGs-based prognostic model with substantially high predictive value,providing the possibility for improved individualized treatment for CRC individuals.

BACKGROUND Complement components could contribute to the tumor microenvironment and the systemic immune response.Nevertheless,their role in colorectal cancer(CRC)remains a contentious subject.AIM To elucidate the relationship between complement components and CRC risk and clinical characteristics.METHODS Searches were conducted in PubMed,the Cochrane Library,and the China National Knowledge Infrastructure database until June 1,2023.We included cohort studies encompassing participants aged≥18 years,investigating the association between complement components and CRC.The studies were of moderate quality or above,as determined by the Agency for Healthcare Research and Quality.The meta-analysis employed fixed-effects or random-effects models based on the I^(2)test,utilizing risk ratio(RR)and their corresponding 95%confidence interval(CI)for outcomes.Sensitivity and subgroup analyses were performed to validate the robustness of the collective estimates and identify the source of heterogeneity.RESULTS Data from 15 studies,comprising 1631 participants that met the inclusion criteria,were included in the meta-analysis.Our findings indicated that protein levels of cluster of differentiation 46(CD46)(RR=3.66,95%CI:1.75-7.64,P<0.001),CD59(RR=2.86,95%CI:1.36-6.01,P=0.005),and component 1(C1)(RR=5.88,95%CI:1.75-19.73,P=0.004)and serum levels of C3(standardized mean difference=1.82,95%CI:0.06-3.58,P=0.040)were significantly elevated in patients with CRC compared to healthy controls.Strong expression of CD55 or CD59 was associated with a higher incidence of lymph node metastasis,whereas strong CD46 expression correlated with a higher incidence of tumor differentiation compared to low CD46 expression(P<0.05 for all).Although specific pooled results demonstrated notable heterogeneity,subgroup analyses pointed to regional differences as the primary source of inconsistency among the studies.CONCLUSION Our analysis underscores that increased levels of specific complement components are associated with a heightened risk of CRC,emphasi

Human epidermal growth factor receptor 2(HER2)-positive breast cancer(BC)has been the most challenging subtype of BC,consisting of 20%of BC with an apparent correlation with poor prognosis.Despite that pyrotinib,a new HER2 inhibitor,has led to dramatic improvements in prognosis,the efficacy of pyrotinib monotherapy remains largely restricted due to its acquired resistance.Therefore,identifying a new potential antitumor drug in combination with pyrotinib to amplify therapeutic efficacy is a pressing necessity.Here,we reported a novel combination of pyrotinib with chrysin and explored its antitumor efficacy and the underlying mechanism in HER2-positive BC.We determined that pyrotinib combined with chrysin yielded a potent synergistic effect to induce more evident cell cycle arrest,inhibit the proliferation of BT-474 and SK-BR-3 BC cells,and repress in vivo tumor growth in xenograft mice models.This may be attributed to enhanced autophagy induced by endoplasmic reticulum stress.Furthermore,the combined treatment of pyrotinib and chrysin induced ubiquitination and glucose-6-phosphate dehydrogenase(G6PD)degradation by upregulating zinc finger and BTB/POZ domain-containing family protein 16(ZBTB16)in tumorigenesis of BC.Mechanistically,we identified that miR-16-5p was a potential upstream regulator of ZBTB16,and it showed a significant inverse correlation with ZBTB16.Inhibition of miR-16-5p overexpression by restoring ZBTB16 significantly potentiated the overall antitumor efficacy of pyrotinib combined with chrysin against HER2-positive BC.Together,these findings demonstrate that the combined treatment of pyrotinib and chrysin enhances autophagy in HER2-positive BC through an unrecognized miR-16-5p/ZBTB16/G6PD axis.

Background:Lung adenocarcinoma is a very pervasive histological form of lung cancers,and inhibiting metastasis is crucial for effective treatment.In this investigation,we explored the functional interaction of miR-30a-5p and the putative transcription factor 2 of the homeodomain(PHTF2)in dictating the aggressiveness and metastasis of lung adenocarcinoma.Method:We collected clinical samples to evaluate the expression patterns of miR-30a-5p and PHTF2 in lung adenocarcinoma along with normal tissues.Cellular experiments including cell count kit(CCK)-8 growth assay,apoptosis analysis,migration and invasion examinations were performed to assess the aggressiveness of lung adenocarcinoma cells.Furthermore,we examined tumorigenesis and metastasis in a nude mouse model.Results:MiR-30a-5p exhibited downregulation pattern in lung adenocarcinoma samples.Transfection of miR-30a-5p mimic in lung adenocarcinoma cells resulted in the suppression of malignant characteristics.Notably,the administration of miR-30a-5p mimic also curbed tumorigenesis and metastasis of lung adenocarcinoma cells in animal model.Moreover,PHTF2 was found to be a molecular target of miR-30a-5p.Upregulating PHTF2 counteracted the tumor-suppressive effect of the miR-30a-5p mimic.Conclusion:miR-30a-5p functions as a tumor-suppressive molecule while PHTF2 acts as an oncogenic factor in the development and metastasis of lung adenocarcinoma.Therefore,targeting miR-30a-5p and PHTF2 could be developed into a promising therapeutic approach for inhibiting metastasis in lung adenocarcinoma.

At the end of 2022,the adjustment of the coronavirus disease 2019(COVID-19)pandemic control policy in China resulted in alarge-scale increase in public infection.To compare the fertility parameters of male patients before and after the adjustments ofthe COVID-19 pandemic control policy in China,we collected data on patients’medical histories and laboratory examinations ontheir first visits between June 2022 and March 2023 in five different hospitals.Data were divided into five groups according tothe timeline of the policy adjustment.The data we collected from male patients included semen quality and serum reproductivehormone levels,and intergroup comparisons were made using the Mann–Whitney U and Chi-square tests.In total,16784 casesunderwent regular semen analysis,11180 had sperm morphology assessments,and 7200 had reproductive hormone analyses.Thedata showed declining trends in semen volume,sperm motility,and the progressive sperm motility rate after the policy adjustment.Subgroup comparison revealed an initial decrease and gradual recovery in progressive motility rate.Sperm morphology analysisshowed increased neck and tail abnormalities after the policy adjustment.No significant change in hormone levels was observed.Following the adjustment of the COVID-19 prevention policy in China,a decline in sperm motility and morphology was observed.This trend may gradually recover over 2 months.After the policy adjustment,reproductive hormone levels were relatively stablethroughout,except for an increase in luteinizing hormone(LH).These changes in semen parameters suggest that the policyadjustment had a short-to medium-term impact on male reproductive function.
