BACKGROUND Venoarterial(VA)extracorporeal membrane oxygenation(ECMO),an effective short-term circulatory support method for refractory cardiogenic shock,is widely applied.However,retrospective analyses have shown that VA-ECMO-assisted cases were associated with a relatively high mortality rate of approximately 60%.Embolization in important organs caused by complications of left ventricular thrombosis(LVT)during VA-ECMO is also an important reason.Although the incidence of LVT during VA-ECMO is not high,the consequences of embolization are disastrous.CASE SUMMARY A 37-year-old female patient was admitted to hospital because of fever for 4 d and palpitations for 3 d.After excluding the diagnosis of coronary heart disease,we established a diagnosis of“clinically explosive myocarditis”.The patient still had unstable hemodynamics after drug treatment supported by VA-ECMO,with heparin for anticoagulation.On day 4 of ECMO support,a left ventricular thro-mbus attached to the papillary muscle root of the mitral valve was found by transthoracic echocardiography.Left ventricular decompression was performed and ECMO was successfully removed,but the patient eventually died of multiple cerebral embolism.CONCLUSION LVT with high mobility during VA-ECMO may cause embolism in important organs.Therefore,a"wait and see"strategy should be avoided.

Introduction:Hepatocellular carcinoma(HCC),a prevalent malignancy,poses signiﬁcant challenges with high tumor heterogeneity and poor prognosis.MicroRNAs(miRNAs)play a pivotal role in hepatocarcinogenesis.Although abnormalities in microRNA-557(miR-557)expression have been implicated in various cancer types,its role in HCC remains unclear.Therefore,there is a need to explore the function of microRNA-557 in HCC.Methods:Candidate miRNAs were identiﬁed through screening in GSE108724 and GSE20077.Real-time PCR was employed to analyze the expression level of miR-557 in hepatoma cell lines and tissues.Cell viability and migration assays were applied to assess the impact of miR-557 on HCC cell lines.Furthermore,the miR-557 target was predicted through three algorithms(Targetscan,miRWalk,and miRanda),and this was conﬁrmed through luciferase assay and Western blotting.Results:In this study,miR-557 was identiﬁed in two datasets and expressed at a low level in both hepatoma cell lines and tissues.Notably,high expression of miR-557 in HCC cells inhibited oncogenesis.Conversely,low expression of miR-557 enhanced tumor proliferation and migration.Polycomb chromobox 4(CBX4)was identiﬁed as a direct target of miR-557.Silencing CBX4 inﬂuenced the functional impact of miR-557 on HCC cell migration.Conclusion:Taken together,our study contributed to elucidating the hepatoma molecular heterogeneity and provided novel insights into miR-557 role and its target CBX4 in HCC,suggesting its potential as a future effectively druggable target for HCC intervention.

Background:The aberrant intraellular expression of a mitochondrial aspartyl tRNA synthetase 2(DARS2)has been reported in human cancers.Nevertheless its critical role and detailed mechanism in lung adenocarcinoma(LUAD)remain unexplored.Methods:Initially,The Cancer Genome Atlas(TCGA)based Gene Expression Profiling Interactive Analysis(GEPIA)database (http:/***/)was used to analyze the prognostic relevance of DARS2 expression in LUAD.Further,cell counting kit(CCK)8,immunostaining,and transwell invasion assays in LUAD cell lines in vitro,as well as DARS2 silence on LUAD by tumorigenicity experiments in wivo in nude mice,were performed.Besides,we analyzed the expression levels of p-PI3K(phosphorylated Phosphotylinosital3 kinase),PI3K,AKT(Protein Kinase B),p-AKT(phosphorylated Protein Kinase B),PCNA(proliferating cell nudear antigen),cleaved-caspase 3,E cadherin,and N-cadherin proteins using the Westem blot analysis.Results:LUAD tissues showed higher DARS2 expression compared to normal tissues.Upregulation of DARS2 could be related to Tumor-Node-Metastasis(TNM)stage,high lymph node metastasis,and inferior prognosis.DARS2 silence decreased the proliferation,migration,and invasion abilities of LUAD cells.In addition,the DARS2 downregulation decreased the PCNA and N-cadherin expression and increased cleaved:caspase 3 and E cadherin expressions in LUAD cells,coupled with the inactivation of the PI3K/AKT signaling pathway.Moreover,DARS2 silence impaired the tumonigenicity of LUAD in vivo.Interestingly,let:7b-5p could recognize DARS2 through a complementary sequence.Mechanistically,the increased let 7b 5p expression attenuated the promo oncogenic action of DARS2 during LUAD progression,which were inversely correlated to each other in the LUAD tssues Conclusion:In summary,let 7b-5p,downregulated DARS2 expression,regulating the progression of LUAD cells by the PI3K/AKT signaling pathway.

Objective Anthracycline-containing regimens are irreplaceable in neoadjuvant chemotherapy(NAC)for breast cancer(BC)at present.However,30% of early breast cancer(EBC)patients are resistant to anthracycline-containing chemotherapy,leading to poor prognosis and higher mortality.Ki-67 is associated with the prognosis and response to therapy,and it changes after NAC.Methods A total of 105 BC patients who received anthracycline-containing NAC were enrolled.Then,the optimal model of Ki-67 was selected,and its predictive efficacy was analyzed.Immunohistochemistry(IHC)was used to determine the estrogen receptor(ER),progesterone receptor(PR),and human epidermal growth factor receptor 2(HER-2)status and Ki-67 level.Fluorescent in situ hybridization(FISH)was used to verify the HER-2 when the IHC score was 2+.Results The post-NAC Ki67 level after treatment with anthracycline drugs was lower than pre-NAC Ki-67(19.6%±23.3%vs.45.6%±23.1%,P<0.001).Furthermore,patients with the Ki-67 decrease had a border line higher pathological complete response(pCR)rate(17.2%vs.0.0%,P=0.068),and a higher overall response rate(ORR)(73.6%vs.27.8%,P<0.001),when compared to patients without the Ki-67 decrease.The ΔKi-67 and ΔKi-67%were valuable markers for the prediction of both the pCR rate and ORR.The area under the curve(AUC)for ΔKi-67 on pCR and ORR was 0.809(0.698-0.921)and 0.755(0.655-0.855),respectively,while the AUC for ΔKi-67% on pCR and ORR was 0.857(0.742-0.972)and 0.720(0.618-0.822),respectively.Multivariate logistic regression model 1 revealed thatΔKi-67 was an independent predictor for both pCR[odds ratio(OR)=61.030,95% confidence interval(CI)=4.709-790.965;P=0.002]and ORR(OR=10.001,95%CI:3.044-32.858;P<0.001).Multivariate logistic regression model 2 revealed thatΔKi-67%was also an independent predictor for both pCR(OR=408.922,95%CI=8.908-18771.224;P=0.002)and ORR(OR=5.419,95%CI=1.842-15.943;P=0.002).Conclusions The present study results suggest thatΔKi67 andΔKi67%are candidate predictors for anthracycline-containing NAC response,and

Objective: To assess the efficacy and safety of Bufei Jiedu(BFJD) Granules as adjuvant therapy for patients with multidrug-resistant pulmonary tuberculosis(MDR-PTB). Methods: A large-scale, multi-center, double-blinded, and randomized controlled trial was conducted in 18 sentinel hospitals in China from December 2012 to December 2016. A total of 312 MDR-PTB patients were randomly assigned to BFJD Granules or placebo groups(1:1) using a stratified randomization method, which both received the long-course chemotherapy regimen for 18 months(6 Am-Lfx-P-Z-Pto, 12 Lfx-P-Z-Pto). Meanwhile, patients in both groups also received BFJD Granules or placebo twice a day for a total of 18 months, respectively. The primary outcome was cure rate. The secondary outcomes included time to sputum-culture conversion, changes in lung cavities and quality of life(QoL) of patients. Adverse reactions were monitored during and after the trial. Results: A total of 216 cases completed the trial, 111 in the BFJD Granules group and 105 in the placebo group. BFJD Granules, as adjuvant treatment, increased the cure rate by 13.6% at the end of treatment, compared with the placebo(58.4% vs. 44.8%, P=0.02), and accelerated the median time to sputum-culture conversion(5 months vs. 11 months). The cavity closure rate of the BFJD Granules group(50.6%, 43/85) was higher than that of the placebo group(32.1%, 26/81; P=0.02) in patients who completed the treatment. At the end of the intensive treatment, according to the 36-item Short Form, the BFJD Granules significantly improved physical functioning, general health, and vitality of patients relative to the placebo group(all P<0.01). Overall, the death rates in the two groups were not significantly different; 5.1%(8/156) in the BFJD Granules group and 2.6%(4/156) in the placebo group. Conclusions: Supplementing BFJD Granules with the long-course chemotherapy regimen significantly increased the cure rate and cavity closure rate, and rapidly improved QoL of patients with MDR-PTB(Registration No. ChiCTR-TRC-

Rationale:Multi-organ failure is a symptom of paraquat poisoning,resulting in high mortality and morbidity rates.Though paraquat is widely available,poisoning through inhalation is rare.Patient’s Concern:A 37-year-old male reported to the emergency department with complaints of vomiting after an alleged history of inhalation of paraquat while at work.Diagnosis:Paraquat poisoning.Interventions:Supportive management along with multiple sessions of hemodialysis.Outcomes:Renal complications caused by paraquat were improved after multiple sessions of hemodialysis.However,the patient developed respiratory complications and later due to persistent hypoxemia and non-responsive to supportive therapy,he succumbed to his illness.Lessons:Acute kidney injury is a complication of paraquat poisoning.However,kidney involvement with the inhalational mode is rare.It is caused by reduction and oxidation cycles,as well as the formation of reactive oxygen species,necessitating hemodialysis as the treatment.Without a clear history,a specific clinical trait,or a diagnostic test,diagnosis can be difficult.Our case thus highlights the inhaled paraquat poisoning,presenting with acute kidney injury with late respiratory impairment as a consequence.

Dear Editor,The tuberculin skin test(TST)reagents have continuously improved,with the ESAT6-CFP10(EC)test having recently been introduced,but are seldom based on the direction of the delayed-type hypersensitivity(DTH)mechanism.Previous studies only partially showed the infiltration and activation of immune cells and the production of cytokines of the skin induration[1,2],and lack the detailed measurements of cell proportions and gene expression in the DTH response.Therefore,in this study,we revealed the comprehensive characteristics of DTH by single-cell RNA sequencing(scRNA-seq)in the guinea pig tuberculosis(TB)model[Experimental Animal Welfare Ethics Committee,Beijing Tuberculosis and Thoracic Tumor Research Institute(2021-064)].
