ObjectiveTo investigate the effects of Yiqi Wenyang Huoxue Lishui components on the cardiac function and mitochondrial energy metabolism in the rat model of chronic heart failure （CHF） and explore the underlying mechanism. MethodsThe rat model of CHF was prepared by transverse aortic constriction （TAC）. Eight of the 50 SD rats were randomly selected as the sham group， and the remaining 42 underwent TAC surgery. The 24 SD rats successfully modeled were randomized into model， trimetazidine （6.3 mg·kg^-1）， and Yiqi Wenyang Huoxue Lishui components （60 mg·kg^-1 total saponins of Astragali Radix， 10 mg·kg^-1 total phenolic acids of Salviae Miltiorrhizae Radix et Rhizoma， 190 mg·kg^-1 aqueous extract of Lepidii Semen， and 100 mg·kg^-1 cinnamaldehyde） groups. The rats were administrated with corresponding agents by gavage， and those in the sham and model groups were administrated with the same amount of normal saline at a dose of 10 mL·kg^-1 for 8 weeks. Echocardiography was used to examine the cardiac function in rats. Enzyme-linked immunosorbent assay was employed to determine the serum levels of N-terminal pro-B-type natriuretic peptide （NT-ProBNP）， hypersensitive troponin（cTnI）， creatine kinase （CK）， lactate dehydrogenase （LD）， free fatty acids （FFA）， superoxide dismutase （SOD）， and malondialdehyde （MDA）. The colorimetric assay was employed to measure the levels of adenosine triphosphate （ATP）， adenosine diphosphate （ADP）， and adenosine monophosphate （AMP） in the myocardial tissue. The pathological changes in the myocardial tissue were observed by hematoxylin-eosin staining and Masson staining. The Na⁺-K⁺-ATPase and Ca²⁺-Mg²⁺-ATPase activities in the myocardial tissue were determined by the colorimetric assay. The ultrastructural changes of myocardial mitochondria were observed by transmission electron microscopy. Western blot was employed to determine the protein levels of ATP synthase subunit delta （ATP5D）， glucose transporter 4 （GLUT4）， and carnitine palmitoyltransferase-1 （CPT-1）. The mitochondrial complex assay kits were used to determine the activities of mitochondrial complexes Ⅰ， Ⅱ， Ⅲ， and Ⅳ. ResultsCompared with the sham group， the model group showed a loosening arrangement of cardiac fibers， fracture and necrosis of partial cardiac fibers， inflammatory cells in necrotic areas， massive blue fibrotic tissue in the myocardial interstitium， increased collagen fiber area and myocardial fibrosis， destroyed mitochondria， myofibril disarrangement， sparse myofilaments， and fractured and reduced cristae. In addition， the rats in the model group showed declined ejection fraction （EF） and fractional shortening （FS）， risen left ventricular end-diastolic diameter （LVIDd）， left ventricular end-systolic diameter （LVIDs）， left ventricular end-diastolic posterior wall thickness （LVPWd）， left ventricular end-systolic posterior wall thickness （LVPWs）， left ventricular end-diastolic volume （LVVOLd）， and left ventricular end-systolic volume （LVVOLs）， elevated levels of NT-ProBNP， cTnI， CK， MDA， FFA， and LD， lowered level of SOD， down-regulated protein levels of GLUT4 and CPT-1， decreased activities of Na⁺-K⁺-ATPase， Ca²⁺-Mg²⁺-ATPase， and respiratory complexes Ⅰ-Ⅳ， and declined levels of ATP5D， ATP， ADP， and AMP （P<0.05， P<0.01）. Compared with the model group， the Yiqi Wenyang Huoxue Lishui components and trimetazidine groups showed alleviated pathological damage of the mitochondria and mycardial tissue， risen EF and FS， declined LVIDd， LVIDs， LVPWd， LVPWs， LVVOLd， and LVVOLs， lowered levels of NT-ProBNP， cTnI， CK， MDA， FFA， and LD， elevated level of SOD， up-regulated protein levels of GLUT4 and CPT-1， increased activities of Na⁺-K⁺-ATPase， Ca²⁺-Mg²⁺-ATPase， and respiratory complexes Ⅰ-Ⅳ， and elevated levels of ATP5D， ATP， ADP， and AMP （P<0.05， P<0.01）. ConclusionYiqi Wenyang Huoxue Lishui components can improve the cardiac function， reduce myocardial injury， regulate glucose and lipid metabolism， optimize the utilization of substrates， and alleviate the damage of mitochondrial structure and function， thus improving the energy metabolism of the myocardium in the rat model of CHF.

Objective To investigate the regulatory effect of KHSRP on progression of gastric adenocarcinoma and the role of the JAK1/STAT3 signaling axis in mediating its effect.Methods KHSRP mRNA expression level was detected using qRT-PCR in 120 pairs of gastric adenocarcinoma and adjacent tissues,4 gastric adenocarcinoma cell lines(MKN-28,HGC-27,CRL-5822,and SNU-1)and normal human gastric mucosal GES-1 cells.In HGC-27 cells with KHSRP knockdown and SNU-1 cells with KHSRP overexpression,cell proliferation,migration,invasion and expression levels of JAK/STAT were evaluated using CCK-8 assay,Transwell migration and invasion assays,and Western blotting.In BALB/c-nude mice,HGC-27 cells with KHSRP knockdown and SNU-1 cells overexpressing KHSRP were injected either subcutaneous or via the tail vein to observe subcutaneous xenograft growth and lung metastasis of the tumor cells.Results Gastric adenocarcinoma tissues and cell lines all showed significantly increased KHSRP expression as compared with the adjacent tissues and GES-1 cells.In HGC-27 cells,KHSRP knockdown significantly inhibited cell proliferation,migration and invasion,while KHSRP overexpression enhanced the malignant behaviors of SNU-1 cells.In nude mice,inoculation of HGC-27 cells with KHSRP knockdown resulted in smaller tumor volume and weight,slower cell proliferation rate and fewer lung metastatic foci,and KHSRP-overexpressing SNU-1 cells produced the opposite results.KHSRP knockdown in HGC-27 cells significantly down-regulated the expression levels of JAK1 and STAT3,which were obviously increased in KHSRP-overexpressing SNU-1 cells.Conclusion High expressions of KHSRP promote progression and metastasis of gastric adenocarcinoma possibly by regulating the JAK1/STAT3 signaling axis.

Objective:To estimate the longitudinal association between serum lipid biomarkers and the development of cardiometabolic multimorbidity (CMM) in middle-aged and old adults (≥45) in China, while examining effect differences among degree of dyslipidemia aggregation and various dyslipidemia combination patterns.Methods:Based on data from the China Health and Retirement Longitudinal Study (2011-2018), logistic regression analysis was used to evaluate the associations of TC, LDL-C, HDL-C, TG (4 forms of dyslipidemias), degree and pattern of dyslipidemia combination with CMM. We also used restricted cubic splines to show the dose-response associations between 4 lipid biomarkers and CMM development.Results:Of the 6 522 participants included, 590 (9.05%) developed CMM. After adjusting for covariates, all 4 forms of dyslipidemias were positively associated with CMM development (high TC: OR=1.33, 95% CI: 1.03-1.71; high LDL-C: OR=1.35, 95% CI: 1.05-1.75; low HDL-C: OR=1.45, 95% CI: 1.19-1.77; high TG: OR=1.50, 95% CI: 1.20-1.88). The U-shaped dose-response relationship between LDL-C and CMM development was observed ( P for non-linear =0.022). The odds of CMM increased with the increase of dyslipidemias forms, which was highest in those with ≥3 forms of dyslipidemias ( OR=2.02, 95% CI: 1.33-3.06). In various dyslipidemia form combinations, the possibility of CMM development was highest in those with high TC, high LDL-C and low HDL-C ( OR=3.54, 95% CI: 1.40-8.67). High TC and high LDL-C were significantly associated with CMM development in people without cardiometabolic diseases. Low HDL-C was positively associated with diabetes and CMM development in participants without cardiometabolic diseases, cardiovascular disease (CVD) followed by diabetes, and diabetes followed by CVD. High TG was positively associated with diabetes and CMM in participants without cardiometabolic diseases, and diabetes followed by CVD. Conclusions:A total of 4 forms of dyslipidemia were all independently associated with CMM development in middle-aged and old adults in China. The dose-response relationship between LDL-C level and CMM development was U-shaped. The aggregation of 4 forms of dyslipidemia were associated with the development of CMM. Low HDL-C and high TG were significantly associated with multiple patterns of cardiometabolic diseases development.

Objective:To investigate the clinical features and prognosis of testicular relapse in pediatric acute lymphoblastic leukemia (ALL).Methods:Clinical data including the age, time from initial diagnosis to recurrence, relapse site, and therapeutic effect of 37 pediatric ALL with testicular relapse and treated in Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences between November 2011 and December 2022 were analyzed retrospectively. Patients were grouped according to different clinical data. Kaplan-Meier analysis was used to evaluate the overall survival (OS) rate and event free survival (EFS) rate for univariate analysis, and Cox proportional-hazards regression model was used to evaluate the influencing factors of OS rate and EFS rate for multivariate analysis.Results:The age at initial diagnosis of 37 pediatric testicular relapse patients was (5±3) years and the time from initial diagnosis to testicular recurrence was (37±15) months. The follow-up time was 43 (22, 56) months. Twenty-three patients (62%) were isolated testis relapse. The 5-year OS rate and EFS rate of the 37 relapsed children were (60±9) % and (50±9) % respectively. Univariate analysis showed that the 2-year EFS rate in the group of patients with time from initial diagnosis to testicular recurrence >28 months was significantly higher than those ≤28 months ((69±10)% vs. (11±11)%, P<0.05), 2-year EFS rate of the isolated testicular relapse group was significantly higher than combined relapse group ((66±11)% vs. (20±13) %, P<0.05), 2-year EFS rate of chimeric antigen receptor T (CAR-T) cell treatment after relapse group was significantly higher than without CAR-T cell treatment after relapse group ((78±10)% vs. (15±10)%, P<0.05). ETV6-RUNX1 was the most common genetic aberration in testicular relapsed ALL (38%, 14/37). The 4-year OS and EFS rate of patients with ETV6-RUNX1 positive were (80±13) % and (64±15) %, respectively. Multivariate analysis identified relapse occurred≤28 months after first diagnosis ( HR=3.09, 95% CI 1.10-8.72), combined relapse ( HR=4.26, 95% CI 1.34-13.52) and CAR-T cell therapy after relapse ( HR=0.15,95% CI 0.05-0.51) were independent prognostic factors for 2-year EFS rate (all P<0.05). Conclusions:The outcome of testicular relapse in pediatric ALL was poor. They mainly occurred 3 years after initial diagnosis. ETV6-RUNX1 is the most common abnormal gene.Patients with ETV6-RUNX1 positive often have a favorable outcome. Early relapse and combined relapse indicate unfavorable prognosis, while CAR-T cell therapy could significantly improve the survival rate of children with testicular recurrence.

Objective To explore the effect of deep learning image reconstruction(DLIR)algorithm combined with"double low"[low voltage(kV)and low contrast agent dosage]technique on the image quality of coronary computed tomography angiography(CCTA)in overweight patients compared with adaptive statistical iterative reconstruction(ASIR-V)and filtered back projection(FBP).Methods Fifty-two patients with body mass index(BMI)between 25.1 kg/m2and 28 kg/m2 who underwent CCTA scanning were prospectively selected,all of whom scanned on a GE Revolution APEX-CT with a tube voltage of 80 kV,a smart mA(500-1 300 mA),a noise index of 30,and a contrast dosage of 0.5 mL/kg;four groups of images were reconstructed for each patient,FBP,50％ASIR-V,DLIR-M,and DLIR-H.The CT and SD values of the aorta(AO)root,the proximal segment of the right coronary artery(RCA),the left circumflex(LCX),the left anterior descending branch(LAD)and the pericardial fat were measured,and the signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated.Two doctors experienced in the diagnosis of cardiovascular disease were selected to subjectively score the reconstructed images using a double-blind method.The SD value,SNR value,CNR value and subjective scores of images in the four groups were compared.Results In the objective image quality evaluation,there were statistically significant differences in SD value,SNR value and CNR value of reconstructed images in the four groups(P＜0.05).As the four groups of reconstruction algorithms FBP,50％ASIR-V,DLIR-M,and DLIR-H were changed sequentially,the image SD value gradually decreased,the SNR value and CNR value gradually increased,and the DLIR-H group had the lowest SD value and the highest SNR and CNR values.In the subjective image quality evaluation,the subjective scores of the two doctors had good consistency(Kappa value=0.900),and the difference between them was statistically significant(P＜0.001).The subjective scores of DLIR-M and DLIR-H groups were higher.Conclusion DLIR algorithm combined with"double-low"technique can significantly improve the CCTA image quality of overweight patients,which is better than 50％ASIR-V and FBP.

Objective To study the clinical characteristics and related factors affecting the severity of acute tinnitus in patients.Methods A retrospective analysis was conducted on the data of 319 patients with acute tinni-tus.All patients had detailed case history,including basic patient information,tinnitus location,course of disease,acoustic characteristics of tinnitus,hearing loss,combined headache,dizziness,aural fallness,earache and other symptoms,as well as accompanying clinical diseases.All patients completed the tinnitus handicap inventory(THI),generalized anxiety disorder(GAD-7),patient health questionnaire(PHQ-9),pittsburgh sleep quality index(PSQI),hyperacusis questionnaire(HQ),type D personality scale-14(DS-14),etc.The mild tinnitus group was determined based on a THI score of ≤36.The moderate tinnitus group was determined based on a THI score of 38～56.The severe to extremely severe tinnitus group was determinded based on THI 56～100.THI grouping was used as the dependent variable and the above factors as independent variables.The correlation between each factor and the severity of acute tinnitus was analyzed using ordered multinomial logistic regression.Results Among 319 patients with acute tinnitus,158(49.5％)were in the mild tinnitus group,and 72(22.6％)were in the moderate tinnitus group,and 89(27.9％)were in severe to extremely severe tinnitus group.Ordered multinomial logistic re-gression analysis found that hyperacusis(OR=3.921),anxiety(OR=2.495),depression(OR=2.921),and D-type personality(OR=0.349)were associated with the severity of acute tinnitus(P＜0.05),with more serere tin-nitus in these patients.Conclusion Hyperacusis,anxiety,depression,and D-type personality may be factors that affect the severity of acute tinnitus,so high attention should be paid when treating patients with acute tinnitus.

Objective: To explore the social functioning characteristics of children with co ocurrence of attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) for intervention reference. Methods: The Chinese Version of Swanson Nolan and Pelham, Version IV Scale-Parent Form(SNAP-IV), the Chinese Version of Weiss Functional Impairment Scale-Parent(WFIRS-P), and the Questionnaire-Children with Difficulties (QCD) were applied to 192 children with ADHD, 243 children with co occurrence of ADHD and ODD, who firstly visited the Department of Children Psychological Health of Zhuhai Maternal and Child Health Care Hospital, and 118 healthy control children from a school in Zhuhai. Results: The scores of attention deficit factor in SNAP-Ⅳ scale of children in three groups were[1.9(1.7, 2.1), 1.8(1.6, 1.9), 1.0(0.6, 1.2)], the scores of hyperactive impulsivity were[1.8(1.4, 2.1), 1.6(1.1, 1.8), 0.7(0.2, 1.0)] the scores of oppositional defiant were[1.6(1.5, 1.9), 1.0(0.8,1.1), 0.8(0.5, 1.0)], the differences were statistically significant( H=268.44, 237.97, 418.66, P <0.01). The dimensions and total scores of the three groups of children s WFIRS-P scale were family[0.8(0.6, 1.1), 0.6(0.3, 0.8), 0.3(0.1, 0.6)]; learning and school[0.8(0.5, 1.1), 0.8(0.5, 1.0), 0.3(0.1, 0.5)]; life skills[1.0(0.7, 1.2), 0.8(0.6, 1.0), 0.6(0.4, 0.8)]; self management [1.0(0.3, 1.0), 0.7(0.3, 1.0), 0.3(0.0, 0.7)]; social activities [0.7(0.4, 1.0), 0.6(0.3, 0.9), 0.3(0.0, 0.4 )]; adventure activities[0.3(0.2, 0.5), 0.2(0.1, 0.4), 0.1(0.0, 0.2)]; the total score[0.8(0.6, 1.0), 0.6(0.5, 0.8), 0.4( 0.2 , 0.6)], the difference between the groups was statistically significant( H=108.82, 122.45, 60.17, 40.58, 96.17, 76.57, 138.30, P <0.01). The difference between the QCD scale scores of children in the three groups was statistically significant[30.0( 24.0 , 37.0), 32.0(27.0, 40.0), 47.0(37.0, 52.3), H=124.65, P <0.01). Multiple regression analysis showed that attention deficit, and oppositional defiant symptoms were associated with both the total WFIRS-P score and the QCD score of children( R 2= 0.40 , 0.25, P <0.05). Conclusion Children with co occurrence of ADHD and ODD have more severe deficits in all dimensions of social functioning than children with ADHD, which might be associated with attention deficit and oppositional defiant symptoms.
