ObjectiveTo establish a tumor prognostic risk assessment model related to target genes of the miR-34 family. MethodsTarget genes of the miR-34 family were screened， and the scores of miR-34 target genes were assessed in 16 tumor types. Univariate Cox regression analysis was used to identify the tumor type with the strongest correlation between miR-34 target gene scores and overall survival （OS）. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） analyses were performed to elucidate the functional roles and signaling pathways of miR-34 target genes. A prognostic risk model based on the miR-34 target genes was constructed using univariate Cox and LASSO regression analyses. Quantitative real-time PCR （qPCR） and dual-luciferase reporter assays were conducted to validate whether the target genes bind to miR-34 and measure their RNA expression levels in the relevant tumors. Additionally， the risk score was integrated with other clinical indicators to develop a nomogram prediction model for patient survival. ResultsA total of 65 target genes of the miR-34 family were screened. The cancer type exhibiting stronger correlation between the target gene scores and OS was lung adenocarcinoma （P = 0.003， HR= 5.150）. Furthermore， miR-34 target genes were predominantly enriched in oxidative stress pathways and various tumor-related processes. Three genes， LDHA， GALNT7， and SATB2， were identified as core components of the prognostic analysis model for lung adenocarcinoma. Additionally， the constructed nomogram model demonstrated robust predictive performance. ConclusionThe risk model and prognosis model of lung adenocarcinoma constructed based on the key target genes of miR-34 have good predictive performance.

Objective: To investigate the mechanism of miR-224-5p on proliferation, apoptosis, invasion and migration of human hepatocellular carcinoma HepG2 cells. Methods : The RNA expression levels of miR-224-5p and early growth responsive gene 2(EGR2) in patients with hepatocellular carcinoma were obtained from the TCGA dataset. Normal human hepatocytes LO2 and hepatoma cells HepG2 were cultured in vitro, and the HepG2 cells were transfected with lentiviral vectors(knockdown of miR-224-5p), small interfering RNA fragments or overexpression vectors(interference and overexpression of EGR2). The expression levels of miR-224-5p and EGR2 in hepatocellular carcinoma cDNA chips and cells were detected by quantitative real-time PCR(qPCR). The expression level of EGR2 protein was detected by Western blot. Dual luciferase reporter gene assay was used to detect the binding of miR-224-5p to EGR2. HepG2 cells positive rate were detected by EdU assay, apoptosis rate was detected by flow cytometry, cell invasion number was detected by Transwell assay, and cell mobility was detected by scratch assay. Results : Compared with paracancerous tissues, the expression of miR-224-5p was increased and the expression of EGR2 mRNA decreased in HCC tissues. Compared with LO2 group, the expression of miR-224-5p in HepG2 cells increased, and the expression of EGR2 mRNA and protein decreased. Compared with the Lv-sh-NC group, the 24 h EdU positive cell rate, cell invasion number, and 48 h cell mobility of HepG2 cells in the Lv-sh-miR-224-5p group decreased, while the apoptosis rate increased. Compared with Oe-NC group, 24 h EdU positive cell rate, cell invasion number, and 48 h cell mobility of HepG2 cells in Oe-EGR2 group decreased, while apoptosis rate increased. Compared with Lv-sh-NC group, the expression of EGR2 protein in Lv-sh-miR-224-5p group increased. Compared with Lv-sh-miR-224-5p+si-NC group, 24 h EdU positive cell rate, cell invasion rate, and 48 h cell mobility of HepG2 cells in Lv-sh-miR-224-5p+si-EGR2 group increased, while apoptosis number decreased. Conclusion miR-224-5p can promote proliferation, invasion, and migration of HepG2 cells and inhibit apoptosis via binding with EGR2.

Objective:To explore the genotypes and clinical phenotypes of three families with Liddle Syndrome(LS).Methods:In this study, three young patients with hypertension and hypokalemia were confirmed LS through second-generation sequencing genetic testing. Members of the three families were screened for genes, and genotypes and clinical phenotypes were analyzed.Results:This study identified three patients in Family 1 carrying a possible pathogenic heterozygous variant c. 1859A>G(p.Y620C) in the SCNN1B gene(sodium channel epithelia 1β subunit). Five patients in family 2 and family 3 carried the pathogenic heterozygous variant c. 1789dup(p.R597Pfs*11) in the SCNN1B gene. Following three months of treatment with salt restriction and triamterene, blood pressure and potassium levels returned to normal in all eight patients.Conclusion:LS patients typically present clinically with early-onset hypertension accompanied by hypokalemia, but there is clinical heterogeneity. It is recommended to conduct genetic testing on suspected patients as early as possible to confirm the diagnosis and initiate timely treatment with effective medications so as to reduce the complications of target organs.

Hypoglycemia can lead to physical and psychological disorders, which are associated with a decrease in quality of life and an increase in mortality risk. Compared to those hospitalized, homebound and community patients have a higher incidence of hypoglycemia and are more vulnerable to the disorders. Hypoglycemia is preventable and treatable, timely intervention can preserve physical well-being of patients and reduce the mortality risk. This article reviews the incidence of hypoglycemia in community diabetic patients, and the knowledge and awareness of patients about hypoglycemia, including the onset inducement, symptoms, hazards, coping and prevention, to provide a reference for the prevention and treatment of hypoglycemia in diabetic patients.

Lung-brain interaction refers to the complex physiological and pathological processes in which the lungs and brain influence and regulate each other through various mechanisms. This process works on the complex network between the lung and brain through multiple levels such as nerve, immune, microbial, metabolic, and gas pathways, and affects development of the diseases. This article aims to provide new ideas and methods for prevention and treatment of related lung and brain diseases, as well as references for subsequent research and clinical practice, by reviewing the physiological and pathological mechanisms of neural pathway, immune pathway, and microbial, metabolic and gas pathways in lung brain interaction.

Objective:To explore the safety and efficacy of Neuroform Atlas stent assisted coil embolization in intracranial wide-necked aneurysms, and analyze the risk factors for procedure-related complications.Methods:A retrospective analysis was performed; the clinical data of 367 patients with 374 intracranial wide-necked aneurysms accepted Neuroform Atlas stent assisted coil embolization from January 2021 to February 2024 were collected. Clinical prognosis, immediate postoperative and 6-12 months postoperative angiography, and procedure-related complications (including perioperative complications and complications during follow-up) were analyzed. Univariate and multivariate Logistic regression analyses were used to identify the independent risk factors for procedure-related complications.Results:Immediate postoperative Raymond-Roy Occlusion Classification (RROC) grading I was noted in 323 aneurysms (86.4%), grading II in 42 aneurysms (11.2%), and grading III in aneurysms (2.4%). Perioperative complications occurred in 26 patients (7.1%): 19 (5.2%) were ischemic complications, while 7 (1.9%) were hemorrhagic complications. A total of 260 aneurysms (69.5%) underwent follow-up angiography, including 229 aneurysms (88.1%) with RROC grading I, 25 aneurysms (9.6%) with grading II and 6 aneurysms (2.3%) with grading III. During the follow-up, 5 patients (1.9%) developed stent stenosis, but only 1 patient had transient ischemic attack, and all of them had boundless vessel occlusion. At the last follow-up, 10 patients (2.7%) had poor prognosis, including 8 (2.2%) with severe disabilities (7 with modified Rankin Scale [mRS] scores of 3 and 1 with mRS scores of 4), and 2 (0.5%) deaths (mRS scores of 6). Multivariate Logistic regression analysis showed that large aneurysms and posterior circulation aneurysms were independent risk factors for procedure-related complications ( OR=6.299, 95% CI: 1.131-35.094, P=0.036; OR=3.654, 95% CI: 1.478-9.035, P=0.005). Conclusion:Neuroform Atlas stent assisted coil embolization in intracranial wide-necked aneurysms is safe and feasible; patients with large aneurysms and posterior circulating aneurysms are more likely to have procedure-related complications.
