Abstract
BACKGROUND Paroxysmal supraventricular tachycardia (PSVT) is characterized by episodes of rapid tachycardia with sudden onset and sudden termination. PSVT treatment has evolved considerably over the past 30 years. Currently, radiofrequency catheter ablation is the first-line treatment. HYPOTHESIS We conducted a randomized controlled trial to compare safety and effectiveness of PSVT ablation between the Jinjiang and Johnson (J&J) catheters in 57 patients in our hospital. METHODS AND RESULTS Patients were randomly assigned to ablation procedures using either the Jinjiang system or the J&J Carto system. Follow-up was performed 3 days, 1, and 6 months after the procedure. Success rate, ablation time, frequency of ablation, and rates of complications and recurrence did not significantly differ between the groups. One Jinjiang group patient (3.6%) experienced arrhythmia recurrence during the 6-month follow-up. CONCLUSIONS The Jinjiang catheter for radiofrequency ablation of PSVT is as safe and effective as the J&J catheter.

Abstract
OBJECTIVE To compare the clinical effects and safety of ultrasound (US)-guided selective cervical nerve root injection (SCNI) and computed tomography (CT)-guided SCNI for patients with cervical radicular pain (CRP). METHODS Forty-two CT-guided SCNI procedures (26 eligible patients) and forty-two US-guided SCNI procedures (25 eligible patients) performed to treat CRP were identified from the medical record system between October 2017 and July 2021 and enrolled in the study. The numeric rating scale was used to assess pre- and postprocedural pain levels, and the neck disability index was used to assess the level of function. All immediate and delayed clinical complications were also recorded. The cost of each procedure and the radiation dose of the CT procedure were documented. The follow-up data were obtained by telephone calls or outpatient visits. RESULTS Five patients in the CT group and one patient in the US group were lost to follow-up at 1 year. No procedure-related complications were observed in either group. Significant pain relief and cervical function improvement were achieved after treatment in both the CT-guided SCNI and US-guided SCNI groups; however, there were no significant differences between the two groups. The average cost per CT-guided SCNI procedure was 133.2 USD, which was higher than the cost per US-guided SCNI procedure (42.2 USD). Meanwhile, the necessary radiation dose per patient in the CT group was 0.36 ± 0.08 mGy. CONCLUSIONS US-guided SCNI and CT-guided SCNI have similar efficacy in treating CRP, but US-guided SCNI is radiation free and less costly than the CT-guided procedure.

Abstract
Acute respiratory distress syndrome is a disease triggered by severe pulmonary and systemic inflammation that may lead to fibrosis and the decline of lung function. Lung capillary endothelial-to-mesenchymal transition (EndMT) is one of the primary sources of fibroblasts in pulmonary fibrosis. The role of miRNAs as molecular markers of pulmonary fibrosis, and miRNAs as nucleic acid drugs has attracted increasing attention. To mock EndMT process, Human pulmonary microvascular endothelial cells (HPMECs) were induced with lipopolysaccharide (LPS). Similarly, LPS treatment was used to generate a mouse model of LPS-induced EndMT and pulmonary fibrosis. LPS-induced EndMT in HPMECs resulted in a significant reduction of miR-23b-3p. miR-23b-3p inhibited the interstitial transition of HPMECs, and miR-23b-3p could mediate this process via inhibiting dipeptidyl peptidase-4 (DPP4). Dual-luciferase assays confirmed the regulatory mechanism of miR-23b-3p. In our mouse model of LPS-induced pulmonary fibrosis, miR-23b-3p and a DPP4 inhibitor (sitagliptin) individually alleviated LPS-induced EndMT progression and pulmonary fibrosis, and their combined use achieved the strongest remission effect. To sum up, miR-23b-3p alleviates EndMT in pulmonary fibrosis by inhibiting the expression of DPP4.

Abstract
Septic acute kidney injury (AKI) contributes to the mortality and morbidity of sepsis patients. Toll-like Receptor 4 (TLR4) has prominent roles in septic AKI. This study investigated the functions of TLR4 in septic AKI. A septic AKI mouse model was established by cecal ligation and puncture surgery. Mouse kidney function and kidney tissue lesion were examined using corresponding kits and H&E staining. The in vitro cell model of septic AKI was established by lipopolysaccharide induction. Cell viability, inflammatory factor (TNF-α, IL-6, IL-4, IL-1β, IL-18) levels, pyroptotic cell number changes, lactate dehydrogenase (LDH) activity, myeloperoxidase (MOP) concentration, and levels of pyroptosis-associated protein and MyD88, TRIF and p38 MAPK phosphorylation were determined by MTT, ELISA, FAM-FLICA Caspase-1 Detection kit, other corresponding kits, and Western blot. TLR4 was highly expressed in septic AKI mouse kidney tissues and human septic AKI cells. TLR4 knockdown alleviated kidney injury, increased cell viability, and reduced LDH activity and MPO concentration. TLR4 knockdown reduced cell pyroptosis by repressing p38 MAPK phosphorylation through MyD88/TRIF, suppressed pro-inflammatory factor (TNF-α, IL-6, IL-4, IL-1β, IL-18) levels, promoted anti-inflammatory factor (IL-4) level, and reduced inflammatory response, thus playing a protective role in septic AKI. Briefly, TLR4 promoted the inflammatory response in septic AKI by promoting p38 MAPK phosphorylation through MyD88/TRIF.

Abstract
Enrichment of Veillonella parvula in the lung microbiota is strongly associated with non-small cell lung cancer (NSCLC) and induces the progression of lung adenocarcinoma in vivo, but its actual role and mechanism remain unexplored. This study analyzed the correlation between NSCLC and V. parvula abundance based on 16 s rRNA sequencing results. The effects of V. parvula on the progression of lung adenocarcinoma were observed in vivo and in vitro using a C57 bl/6j mouse tumor-bearing model, a bacterial cell co-culture model, combined with transcriptome sequencing, and a TCGA database to explore and validate the growth promotion of lung adenocarcinoma by V. parvula and its molecular mechanism. 16 s rRNA sequencing revealed that V. parvula was significantly enriched in lung adenocarcinoma. In vivo, V. parvula promoted the growth of lung adenocarcinoma in mice by suppressing the infiltration of tumor-associated T lymphocytes and peripheral T lymphocytes. It showed a higher affinity for lung adenocarcinoma in vitro and promoted lung adenocarcinoma cell proliferation through adhesion or intracellular invasion. Further analysis of differential gene expression and KEGG enrichment by transcriptome sequencing revealed that V. parvula induced CCN4 expression and activated NOD-like receptor and NF-κB signaling pathway in lung adenocarcinoma cells. Further analysis clarified that V. parvula promoted activation of the NF-κB pathway via Nod2/CCN4 signaling, which promoted lung adenocarcinoma cell proliferation. Thus, V. parvula mediates activation of the Nod2/CCN4/NF-κB signaling pathway to promote non-small cell lung adenocarcinoma progression, thereby providing a potential target for diagnosing and treating lung adenocarcinoma.

Abstract
PURPOSE The abnormal expression of tight junction (TJ) plays a vital role in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP). However, there is no appropriate tool to distinguish and diagnose epithelial barrier defects in clinical practice. This study aimed to evaluate the predictive value of claudin-3 for epithelial barrier dysfunction in CRSwNP. METHODS In this study, TJ protein levels were evaluated by real-time quantitative polymerase chain reaction, immunofluorescent, and immunohistochemistry staining in control subjects and CRSwNP patients. The receiver operating characteristic (ROC) curve was created to assess the predictive value of TJ breakdown in clinical outcomes. In vitro, human nasal epithelial cells were cultured at the air-liquid interface to analyze the transepithelial electrical resistance (TER) level. RESULTS The expression levels of occludin, tricellulin, claudin-3, and claudin-10 were decreased (all P < 0.05), and those of claudin-1 was increased (P < 0.05) in CRSwNP patients as compared to healthy subjects. Additionally, claudin-3 and occludin levels were negatively correlated with the computed tomography score in CRSwNP (all P < 0.05), and the ROC curve indicated that the claudin-3 level had the most predictive accuracy in evaluating epithelial barrier disruption (area under the curve = 0.791, P < 0.001). Finally, the time-series analysis showed the highest correlation coefficient between TER and claudin-3 (cross-correlation function = 0.75). CONCLUSION In this study, we suggest that claudin-3 could be a valuable biomarker for predicting nasal epithelial barrier defects and disease severity in CRSwNP.

Abstract
BACKGROUND Zinc finger protein 687 (ZNF687) has previously been discovered as a potential oncogene in individuals with giant cell tumors of the bone, acute myeloid leukemia, and hepatocellular carcinoma. However, its role and mechanism in lung adenocarcinoma (LUAD) remain unclear. METHODS In LUAD cells, tumor, and matched adjacent tissue specimens, quantitative real-time RT- polymerase chain reaction (qRT-PCR), western blotting analyses, and immunohistochemistry staining (IHC) were conducted. Cell counting kit-8 (CCK8) assay, clonogenicity analysis, flow cytometry, and transwell assays were utilized to detect ZNF687 overexpression and knockdown impacts on cell growth, colony formation, cell cycle, migration, and invasion. Bioinformatic studies, qRT-PCR and western blotting studies were employed to validate the underlying mechanisms and signaling pathways implicated in the oncogenic effect of ZNF687. RESULTS This study demonstrated that ZNF687 expression was elevated in LUAD cells and tissues. Individuals with upregulated ZNF687 had a poorer prognosis than those with downregulatedZNF687 (p < 0.001). ZNF687 overexpression enhanced LUAD growth, migration, invasion and colony formation, and the cell cycle G1-S transition; additionally, it promoted the epithelial-mesenchymal transition (EMT). In contrast, knocking down ZNF687 showed to have the opposite impact. Moreover, these effects were associated with the activity of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling mechanism. CONCLUSION ZNF687 was upregulated in LUAD, and high ZNF687 expression levels are associated with poor prognoses. The activation of the PI3K/AKT signaling pathway by upregulated ZNF687 increased the proliferation of LUAD cells and tumor progression. ZNF687 may be a beneficial predictive marker and a therapeutic target in LUAD.

Abstract
BACKGROUND Preeclampsia (PE) is one of the most serious pregnancy complications with unknown pathogenesis. Emerging evidence has demonstrated that Fms-related tyrosine kinase 1 (FLT1) is highly involved in PE development. As a pseudogene of FLT1, FLT1P1 increased in PE samples. However, its functions remain largely unknown. METHODS AND RESULTS In this study, co-expression analysis was performed to identify the potential target genes of FTL1P1. Then chromatin isolation using RNA purification (ChIRP) method was employed to explore the interactomes of FLT1P1, including interacting with DNA fragments and proteins. We found that in PE samples, both FLT1P1 and FLT1 were highly expressed and closely correlated. ChIRP-protein data revealed that FLT1P1 interacts with translation- and transcription-related proteins, including 4 transcription factors (TFs). ChIRP-DNA analysis revealed that FLT1P1 preferentially interacted with DNA fragments downstream of transcription start sites (TSSs). Functional analysis of its interacting genes revealed that they were enriched in transcriptional regulation and apoptosis-related pathways. Twenty-six TFs, including CREB1 and SRF, were extracted from the potential FLT1P1-interacting gene sets and were potential targets of FLT1P1. CREB1 could bind to FLT1 promoter, and was negatively correlated with FLT1 at the expression level, making it a potential regulator of FLT1. CONCLUSIONS Our study extensively investigated the interactome profiles of FLT1P1, especially the prompter region of TF gene CREB1, and revealed the potential molecular regulatory mechanisms of FLT1 expression in PE samples. Our results provide a novel view of PE pathogenesis, and suggest that FLT1P1 could serve as a potential therapeutic target in PE diagnosis and treatment.
