Objective To explore the effect and underlying molecular mechanism of miR-101 on ventricular remodeling in rats after acute myocardial infarction (AMI). Methods The AMI rat model was established using the left anterior descending coronary artery ligation method. The AMI rats were randomly divided into AMI group, agomir-NC group, miR-101 agomir group and coumermycin A1 group, another 12 rats were selected as sham group with 12in each . The targeting relationship between miR-101 and JAK2 was analyzed by Target Scan 8.0 database and double luciferase reporter gene assay. The expression of miR-101 in rat myocardium was detected by RT-qPCR. LVESD, LVEDD, LVEF and LVFS were measured by ultrasonography. The level of IL-1β, IL-6 and TNF-α in rats serum was determined by ELISA. The myocardial tissue lesion and fibrosis were detected by HE staining and Masson staining. The expression of collagenⅠ and TGF-β in rat myocardial tissue was detected by immunohistochemical staining. The expression of E-cadherin, N-cadherin, Vimentin, p-JAK2, JAK2, p-STAT3 and STAT3 proteins was detected by Western blot. Results Compared with AMI group and agomir-NC group, the myocardial tissue lesions and fibrotic area in miR-101 agomir group were significantly decreased(P＜0.05), the level of LVESD, LVEDD, L-1β, IL-6, TNF-α, collagenⅠ, TGF-β, N-cadherin, vimentin, p-JAK2 and p-STAT3 decreased (P＜0.05).

Objective To explore the correlation between the expression of microRNA-452 (miR-452) and micro-RNA-221 (miR-221) in peripheral blood and post-operative urinary sepsis after percutaneous nephrolithotripsy (PCNL). Methods From January 2019 to June 2023, 92 patients with post-operative urinary sepsis after PCNL admitted to 909 Hospital of the Chinese People′s Liberation Army Joint Logistic Support Force were regarded as the disease group, 92 patients who underwent PCNL surgery during the same period without urinary sepsis were collected as control group. RT-qPCR was applied to detect the expression of miR-452 and miR-221 in peripheral blood; Logistic regression was applied to analyze the influencing factors of urinary sepsis after PCNL surgery; Receiver operating characteristic (ROC) curve was applied to evaluate the diagnostic efficacy of peripheral blood miR-452 andmiR-221 levels for post-operative urinary sepsis in PCNL patients. Results The time length of the surgical operation in disease group was longer than that in the control group, and the level of miR-452 and miR-221 in peripheral blood, were higher than those in the control group (P＜0.05). Peripheral blood miR-452, miR-221, procalcitonin (PCT), C-reactive protein (CRP), neutrophil to lymphocyte ratio (NLR), urine routine and surgical time were all influence factors for post-operative urinary sepsis in PCNL (P＜0.05). The area under the curve (AUC) for the combined diagnosis of peripheral blood miR-452 and miR-221 in patients with urinary sepsis after PCNL surgery was 0.888, which was better than their individual detection (Z_{combination-miR-452}=2.005, Z_{combination-miR-221}=2.972, P=0.045, 0.003), the sensitivity and specificity were 77.17% and 91.30%, respectively. Conclusions The change of miR-452 and miR-221 level in peripheral blood is closely related to urinary sepsis after PCNL. Combined testing has a high diagnostic efficacy for post-operative urinary sepsis after PCNL surgery.

Objective To investigate the relationship between the protective mechanism of dexmedetomidine (Dex) against myocardial ischemia-reperfusion(I/R) injury and cuproptosis. Methods The Langendorff models were constructed using SD rats(I/R group), which were divided into 4 groups according to different interventions during reperfusion as: sham group, I/R group, Dex group and Dex+ES-Cu group. The left ventricular peak pressure(LVSP)of the rats in the above four groups were continuously monitored in the immediate pre-ischemic period(T0), 30 min of reperfusion(T1), 60 min reperfusion(T2), 90 min reperfusion(T3),2 h of reperfusion(T4). Left ventricular end-diastolic pressure(LVEDP), heart rate (HR), maximum rate of rise of left ventricular pressure (+dp/dtmax) and maximum rate of drop. Subsequently, the extent of myocardial infarction was shown by1% triphenyltetrazoliumchloride (TTC) staining, and the degree of myocardial fibrosis was assessed by Sirius red staining; Myocardial enzyme profiles, oxidative stress and inflammation indexes were detected by ELISA; Copper ions were detected by copper ion detection kit in myocardial tissues; ATF3, SPI1 and FDX1 protein level expression was detected by Western blot. Results Compared with the sham-operated group, the extent of myocardial infarction and fibrosis increased in the I/R group(P＜0.05), the level of serum MDA, IL-6, IL-1β, and TNF-α was elevated(P＜0.05), and the activity of SOD and GSH-Px decreased(P＜0.05). The Dex group significantly alleviated the above changes in the I/R group, and compared with the Dex group, in the Dex+ES-Cu group myocardial tissue copper ion content at the end of perfusion was increased(P＜0.05). Both ATF3 and SPI1 protein were increased and FDX1 protein was decreased(P＜0.05). Conclusions Dex can regulate copper metabolism and improve myocardial ischemia-reperfusion injury(MI/RI) resulted from oxidative stress and inflammation in rat model.

Objective To explore the relationship between miR-409-3p and miR-325-3p with the efficacy of interventional therapy in patients with primary liver cancer. Methods Ninety-six patients with primary liver cancer who visited Nanyang Central Hospital from October 2021 to January 2024 were regarded as the liver cancer group. All patients underwent transcatheter arterial chemoembolization(TACE)treatment and were separated into an effective group(complete remission,partial remission)and an ineffective group(disease stability, disease progression)basedon the treatment effect. Totally 91 patients with liver cirrhosis who underwent treatment in our hospital during the same period were selected as liver cancer group and 98 healthy individuals who received physical examinations during the same period were selected as the healthy group. Serum miR-409-3p,miR-325-3p levels were detected and analyzed for their correlation. Logistic regression was applied to analyze the relevant factors affecting the efficacy of TACE treatment. Receiver operating characteristic(ROC) curve was applied to evaluate their predictive value for TACE treatment efficacy of serum miR-409-3p,miR-325-3p levels. Results Compared with the healthy group,the serum level of miR-409-3p and miR-325-3p in the liver cirrhosis group and liver cancer group were reduced(P＜0.05). Compared with the liver cirrhosis group,the serum level of miR-409-3p and miR-325-3p in the liver cancer group were also reduced(P＜0.05). Compared with the effective group,the serum level of miR-409-3p and miR-325-3p in the ineffective group significantly decreased(P＜0.05). There was a positive correlation between serum level of miR-409-3p and of miR-325-3p in patients with primary liver cancer(r=0.472,P＜0.001). The elevated level of miR-409-3p and miR-325-3p were protective factors for ineffective TACE treatment in primary liver cancer patients(P＜0.05). The combination of serum miR-409-3p and miR-325-3p was superior to single prediction in predicting efficacy after TACE treatment in primary liver cancer patients(Z_{combination - miR-409-3p}=4.556,P＜0.001,Z_{combination-miR-325-3p}=2.613,P＜0.01). Conclusions The serum level of miR-409-3p as well as miR-325-3p is both reduced in patients with primary liver cancer,and is related to the efficacy of interventional therapy.

Objective To investigate the effects of miR-338-3p on interleukin (IL) -13-induced human bronchial epithelial cell line (BEAS-2B) injury and airway inflammation in mice with ovalbumin (OVA) -induced asthma. Methods OVA was used to replicate an asthma model of mice, which were divided into control group, model group, miR-NC agomir and miR-338-3p agomir intervention groups. HE staining microscopy was employed to observe the pathological morphology of lung tissue, while TUNEL staining was used to assess cell apoptosis in lung tissue. ELISA was conducted to measure the levels of interleukin-1β (IL-1β) and tumor necrosis factor (TNF)-α in lung tissue. The BEAS-2B cells were subjected to IL-13-induced injury and divided into control group, IL-13group, IL-13+miR-NC group, and IL-13+miR-338-3p mimic group. Cell viability was assessed with MTT assay. Flow cytometry was employed to evaluate cell apoptosis. The level of IL-1β and TNF-α in cells was measured by ELISA. The targeting relationship between miR-338-3p and Ras homologous (Rho) was investigated using bioinformatics analysis, luciferase assay, Western blot, and functional repair assay. Results Compared to the model group, the miR-338-3p agamid intervention group exhibited a significant reduction in inflammatory cell infiltration and airway wall thickening in lung tissue, as well as decreased cell apoptosis and the level of IL-1β and TNF-α in lung tissue (P＜0.05). Compared to the control group, cell viability of BEAS-2B cells in the IL-13+miR-338-3p mimic group exhibited a significant increase (P＜0.05), while apoptosis and level of IL-1β and TNF-α within the cells demonstrated a notable decrease (P＜0.05). Rho was a target gene of miR-338-3p, and over-expression of Rho attenuated the effect of miR-338-3p mimic on IL-13-induced injury and inflammation in BEAS-2B cells. Conclusions Up-regulation of miR-338-3p can inhibit asthma-related airway inflammation and injury of lung epithelial cells with a potential mechanism targeting at Rho gene.

Objective To evaluate the impact of different CO₂ fractional laser parameters on the formation of microscopic treatment zone (MTZ) on the nail surface and to compare the observations of these areas using various instruments. Methods This study applied 60 different combinations of CO₂ fractional laser parameters, including pulse widths ranging from 100-1 000 μs and powers from 10-60 W, on bovine hoof samples. The formation and overall changes of MTZ on the nail surface were subsequently observed and compared using optical microscopy, inverted microscopy, and white light interferometry. The relationships between MTZ and various laser parameters were analyzed. Results Significant statistical differences were observed between white light interferometry and inverted microscopy in MTZ assessment(P＜0.001). White light interferometry demonstrated greater accuracy and reliability in measuring micro-ablative column(MAC) and thermal coagulation zone (TCZ). There were also significant statistical differences in MAC formation based on CO₂ fractional laser parameters(P＜0.001), with the strongest correlation found between pulse width and MTZ(0.656 68-0.772 62). Longer pulse widths correlated with larger MACareas and depths, as well as increased TCZ thickness. Conclusions White light interferometry shows significant advantages in assessing the impact of CO₂ fractional laser ablation on tissue depth. These findings provide valuable insights for optimizing laser parameters in the treatment of nail disorders and contribute to enhancing the safety and efficacy of such therapies.

Objective To investigate the correlation between coagulation system biomarkers and bone mineral density (BMD) in patients with spinal degenerative diseases. Methods A total of 251 patients who underwent surgical treatment for spinal degenerative diseases at the Department of Spinal Surgery, Beijing Jishuitan Hospital, from March to October 2019, were enrolled in this study. These patients had both BMD data and coagulation system test Results available. The distribution of coagulation indicators, including prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen(Fib), and thrombin time (TT), was analyzed across different gender and BMD groups. Results A retrospective analysis of laboratory coagulation indicators revealed that in male patients, only fibrinogen levels were significantly increased with the reduction of BMD (P＜0.05). PTand APTT did′t show significant differences in female patients across BMD groups, but fibrinogen levels increased with the decrease in BMD (P＜0.05). Patients were classified into osteoporosis and non-osteoporosis groups based on their BMD Results. Pearson correlation analysis was performed between the binary variable of BMD grouping and patients′ coagulation indicators. TheResults showed a significant negative correlation between BMD grouping and fibrinogen levels in both genders (P＜0.05). Conclusions Fibrinogen level in patients with spinal degenerative diseases significantly increases as BMD decreases, suggesting that fibrinogen may serve as a predictive biomarker for BMD stratification in these patients.

Methods The electronic medical record system data of children diagnosed with NEC who underwent partial enterocolectomy in the Second Affiliated Hospital of Xi′an Jiaotong University from January 2018 to January 2023 were retrospectively reviewed. According to the occurrence of PPCs in 7 days after surgery, the children were divided into two groups: PPCs group and non-PPCs group. Pre-operative, intra-operative and post-operative data of the children from two groups were collected and statistically analyzed. Risk factors for PPCs were screened out by univariate independent variables, and variables with differences between groups in univariateanalysis were included in multivariate Logistic regression analysis to further determine the risk factors for PPCs in NEC. Results A total of 216 children meeting the criteria were included, of which 86(40%) had PPCs and 130(60%) had no PPCs. The Results of univariate Logistic regression analysis showed that pre-operative low body mass, low gestational age, high American Society Anesthesiologists(ASA)grade, low pre-operative hemoglobin level, intra-operative volume control ventilation, no positive end expiratory pressure(PEEP), intra-operative hypoxemia were correlated with the occurrence of PPCs in the two groups, and the differences were statistically significant(P＜0.05). Through the Results of univariate analysis, collinear variables were corrected, and variables with differences between groups were included in multivariate Logistic regression. It was found that pre-operative low body weight(OR=0.262, 95% CI:0.144-0.447, P＜0.001),intra-operative volume control ventilation(OR=0.471, 95% CI:0.261-0.850, P＜0.05) and intra-operative PEEP(OR=0.064, 95% CI:0.007-0.623, P＜0.05) were identified as risk factors for PPCs in children with NEC. Conclusions Pre-operative low body weight, intra-operative volume control ventilation and non-use of PEEP are independent risk factors for PPCs in children with NEC.

Objective To study the performance of serum amyloid A (SAA), procalcitonin (PCT) and hypersensitive C-reactive protein (hs-CRP) in predicting and evaluating therapeutic efficacy of neonatal septicemia. Methods Totally 63 neonates with clinical diagnosis of septicemia and 50 healthy neonates as control from January 2021 to April 2024 were enrolled this study. The clinical features and the Results of SAA, PCT and hs-CRP were compared between the two groups; The Results of SAA, PCT and hs-CRP of neonates suffering from septicemia with different therapeutic outcomes were compared. Results There was no significant difference in clinical features(age, birth weight, mode of delivery, etc.) between the two groups, and the positive rate of blood culture in neonates with septicemia was only 12.7%, gram-positive cocci were the main pathogens; The level of SAA, PCT and hs-CRP in sepsis group was significantly higher than those in control group(P＜0.01);The area under the receiver operating characteristic(ROC) curve(AUC) of the three indexes was higher than 0.7, and the AUC of the combined detectionwas 0.9, the sensitivity was 90.55%; The Results of the three indexes were significantly decreased in effective group after treatment(P＜0.01), and the AUC of the joint detection in evaluating therapeutic efficacy was 0.77, the sensitivity and specificity were 65.36% and 82.45% respectively. Conclusions A combined detection of SAA, PCT and hs-CRP shows high value in diagnosis and prognosis prediction of neonatal septicemia.

Hyperuricemia (HUA), characterized by abnormal uric acid (UA) metabolism, leads to the accumulation of urate salts within the kidney. This accumulation not only disrupts glomerular filtration and tubular reabsorption functions but also triggers oxidative stress, inflammation,and up-regulating the renin-angiotensin-aldosterone system (RASS), all of which damage renal cells and tissues. These mechanisms contribute to renal fibrosis and accelerate the progression of diabetic nephropathy (DN)/diabetic kidney disease(DKD). These findings underscore the role of HUA as a risk factor for the advancement of DKD, emphasizing the critical importance of effective UA control in delaying its development.

Endometrial injury disease is a kind of uterine disease of thin endometrium and intrauterine adhesion caused by endometrial basal layer damage. The current clinical use of drug therapy and hysteroscopy surgery can not have good curative effects. Mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) can secrete a variety of active factors to regulate the inflammatory response and immune response of endometrial, promote endometrial proliferation and repair, and there is a mutual promoting effect between the two. Combined use can provide a new idea for the clinical treatment of endometrial injury diseases.

Intestinal ischemia-reperfusion (I/R) injury firstly causes damage to the intestine itself. After the intestinal barrier and function are impaired, bacteria, metabolites and endotoxins in the intestine will enter the portal system through the damaged intestinal mucosa, and then participate in the systemic microcirculatory system through the liver to act on the distal organs. This leads to further damage and induces reperfusion syndrome and multiple organ dysfunction syndromes (MODS), which can lead to death in severe cases.

Migraine is a complex neurological disorder with unknown etiology, involving genetic and environmental factors. The pathogenesis of migraine is closely related to the activation of microglia and inflammatory factors. ATP is a ligand for the P2X receptor (P2XR), a ligand gated ion channel (LGIC) widely expressed in neurons and glial cells. This review elucidates that P2X (P2X3, P2X4, P2X7) receptors regulate the activation of microglia and release of inflammatory factors through different signaling pathways, mediating neuropathic pain and migraine occurrence, providing potential targets for the treatment of migraine.
