Chinese Journal of Immunology 2025;41(1):75-84
Objective:To explore the mechanism of long non-coding RNA nuclear-enriched transcript 1(LncRNA NEAT1)on improving myocardial injury in rats with myocardial infarction(MI)mechanism through miR-136/extracellular signal-regulated kinase 1/2(ERK1/2)axis.Methods:Using the random number table method,120 male SD rats were divided into 6 groups(n=20):sham group,myocardial infarction group(MI group),control interference group(sh-NC group),NEAT1 interference group(sh-NEAT1 group),NEAT1 interference+miR-136 control inhibition group(sh-NEAT1+antagomiR-NC group)and NEAT1 interference+miR-136 suppression group(sh-NEAT1+antagomiR-136 group).Seven days before MI operation,100 μl of corresponding adenovirus vector was injected into the myocardium.Rats in each group were ligated the left anterior descending vessel to establish MI model.In sham group,only the left chest was opened and the heart was exposed without ligation.H9C2 cardiomyocyte were divided into:control group,vehicle group,sh-NC group,sh-NEAT1 group,sh-NEAT1+antagomiR-NC group and sh-NEAT1+antagomiR-136 group.Car-diomyocyte were transfected with corresponding NEAT1 interference vector and negative control,miR-136 inhibitor and negative con-trol.StarBase prediction and dual luciferase report experiment verify the targeted regulation of LncRNA NEAT1 on miR-136;myocar-dial infarct size was measured by TTC staining,and myocardial histopathological changes were observed by HE staining;Echocardiog-raphy was used to detect rat cardiac function;detection of apoptosis in rat myocardial tissue and H9C2 cells by flow cytometry.ELISA method was used to detect serum oxidative stress,corresponding indexes of myocardial enzymes and the contents of inflammatory fac-tors in myocardial tissue and H9C2 cells.CCK8 and EdU staining were used to detect the proliferation ability of H9C2 cells.RT-qPCR was used to detect the expressions of miR-136,SIRT1 mRNA in myocardial tissue and H9C2 cells.Western blot was used to detect the expressions of ERK1/2,p-ERK1/2,B-cell lymphoma-2(Bcl-2),Bcl2-related X protein(Bax)protein in rat myocardial tissue and H9C2 cells.Results:The expression of LncRNA NEAT1 was up-regulated in injured myocardial tissues and cells,and the expression of miR-136 was down-regulated(P<0.05).At the same time,NEAT1 targets and regulates the level of miR-136.Inhibition of NEAT1 expression could increase left ventricular ejection fraction(LVEF),left ventricular fraction shortening(LVFS),Bcl-2 level,and de-crease the activities of creatine kinase(CK),lactate dehydrogenase(LDH),and aspartame Acid transaminase(AST),superoxide dismutase(SOD),reduce Bax,troponin Ⅰ(cTnⅠ),malondialdehyde(MDA),TNF-α,IL-1β,IL-6,ERK1/2/p-ERK1/2 levels(P<0.05),promote the proliferation of myocardial cells,inhibit cell apoptosis,reduce the area of myocardial infarction,inhibit oxida-tive stress and inflammation,and improve myocardial damage Inhibiting miR-136 can save the above effects.Conclusion:The expres-sion of LncRNA NEAT1 is up-regulated and the expression of miR-136 is down-regulated in injured myocardial tissue and cells.Inhibi-tion of LncRNA NEAT1 expression inhibits apoptosis,oxidative stress and inflammation through miR-136/ERK1/2 axis,thus improving myocardial injury.

4.Research Progress in miRNA-mediated Regulation of Glucose Metabolism Pathways in Type 2 Diabetes Mellitus(T2DM)
Chinese Journal of Biochemistry and Molecular Biology 2025;41(10):1467-1477
Type 2 diabetes mellitus(T2DM)is a chronic metabolic disorder characterized primarily by pancreatic β-cell dysfunction and insulin resistance.Beyond impaired glucose homeostasis,the glucotox-icity resulting from dysregulated glucose metabolism can lead to complications such as diabetic nephropa-thy,diabetic coronary heart disease,and diabetic cognitive dysfunction,posing severe threats to patients' health.Therefore,enhancing glucose metabolism and improving insulin resistance are critical strategies for T2DM prevention and treatment.Currently,the primary therapeutic approaches for T2DM include oral hypoglycemic agents and exogenous insulin injections.However,these methods face challenges such as unclear diagnostic markers,suboptimal therapeutic efficacy,and drug-related side effects.Consequently,the development of more precise and effective treatment strategies remains a top priority in clinical re-search.MicroRNA(miRNA)is a short non-coding RNA that regulates gene transcription.It has been reported to exhibit significant alterations even before the onset of overt pathological features like hypergly-cemia,suggesting their potential as early diagnostic biomarkers for T2DM to address current issues like delayed diagnosis and disease progression due to missed optimal treatment windows.Moreover,miRNAs can modulate the expression of pathways involved in glucose metabolism,thereby improving insulin resist-ance and maintaining glucose homeostasis while avoiding side effects associated with conventional thera-pies,such as reduced bone density and localized fat accumulation.This positions miRNAs as a promising avenue for precise and efficient T2DM management.This article systematically elucidates the molecular mechanisms by which miRNAs regulate glucose metabolism-related pathways,providing a theoretical foundation and reference for future clinical research.

Objectives:
Vertebral fractures are associated with disability and mortality, but most vertebral fractures are asymptomatic. The present study aimed to determine the incidence of and develop a predictive nomogram for asymptomatic vertebral fractures in Vietnamese adults.
Methods:
This cohort study as a part of the Vietnam Osteoporosis Study involved 168 men and 287 women aged 50 years and older without a clinically diagnosed vertebral fracture. Their spine x-rays were taken at the recruitment and subsequent 2-year visit. Vertebral fractures were ascertained using the Genant’s semiquantitative method. We employed the Bayesian Model Averaging method to search for the optimal model for predicting asymptomatic vertebral fractures. A predictive nomogram was also developed to facilitate risk prediction.
Results:
During a median of 2.38 years of follow-up, 13 men and 16 women developed an asymptomatic vertebral fracture, yielding the overall incidence rate of 28 fractures per 1000 person-years, or 33 fractures/1000 personyears in men and 24 fractures/1000 person-years in women, respectively. Most asymptomatic vertebral fractures were moderate, almost 1.5 times more common than mild fractures. The optimal model for predicting incident asymptomatic vertebral fractures included age, male sex and lower femoral neck T-score. The area under the receiver’s operating characteristic curve was 0.91, with 95% CI ranging from 0.86 to 0.96.
Conclusions
Asymptomatic vertebral fractures were relatively common among adults in Vietnam. A simple model with sex, age and femoral neck T-score is helpful for selective screening of asymptomatic vertebral fractures in Vietnamese individuals.

Objective:To evaluate the consistency between architectural distortion(AD)observed on coronal images in three-dimensional ultrasonography(3D-US)and full-field digital mammography(FFDM),and to analyze the influencing factors of the presence of AD on 3D-US coronal images.Methods:A retrospective study was conducted on 96 female patients(97 lesions)with AD identified via FFDM that examined at Affiliated Hangzhou First People's Hospital,School of Medicine,Westlake University from January 2019 to December 2021,all of which with corresponding 3D-US results. Kappa analysis was used to assess the consistency between AD on 3D-US and FFDM.The differences of the lesion characteristics on FFDM(glandular density,presence of calcifications,and degree of distortion),3D-US features(number of lesions,presence of mass or non-mass lesions,and skipping sign in coronal images),clinical pathological characteristics(age,location,and pathology)between groups with AD and without AD in 3D-US were compared. Multivariate Logistic regression was used to identify the influencing factors.Results:Among the FFDM-identified AD lesions,62(63.92%,62/97)lesions showed AD on 3D-US coronal images,including 30 malignant lesions(48.39%,30/62);35(36.08%,35/97)lesions without AD on 3D-US,in which 4(11.43%,4/35)were malignant. The consistency of distortion degree between FFDM and 3D-US was moderate(Kappa=0.455, P<0.001),with no statistically significant difference( χ2=2.882, P=0.143). The probability of malignancy was higher in typical AD compared to atypical AD. The comparisons of age,location,number of lesions,presence of skipping sign in 3D-US,breast density,and presence of calcification in the lesion showed no statistically significant differences between the groups with and without AD(all P >0.05).The pathological results of malignancy,presence of lesions in 3D-US(mass and non-mass lesions),and the degree of distortion in FFDM showed statistically significant differences(all P < 0.05). The multivariate Logistic regression analysis indicated that there were no independent risk factors for the appearance of AD in 3D-US(all P > 0.05). Conclusions:In breast FFDM AD lesions,the incidence of 3D-US coronal plane AD was 63.92%,and the consistency between the degree of distortion in FFDM and 3D-US was moderate. The probability of malignancy is higher with typical AD. Pathological malignancy,presence of lesions in 3D-US(both mass and non-mass lesions),and typical AD in FFDM are more likely to correspond with AD in the coronal.
