Efficacy and safety analysis of continued nursing of complications in discharged patients after percutaneous transhepatic biliary drainage.

BACKGROUND: Percutaneous hepatobiliary drainage (PTCD) is an effective method for the treatment of biliary obstruction and other diseases, but postoperative complications are still one of the important problems faced by patients. Continuous nursing is a comprehensive nursing model that plays an important role in postoperative recovery. The purpose of this study was to investigate the effect of continuous nursing on the incidence of complications in patients after PTCD surgery through meta-analysis and to evaluate its efficacy and safety. AIM: To evaluate the effect of extended nursing on the incidence of complications in discharged patients after percutaneous transhepatic biliary drainage (PTBD). METHODS: Randomized controlled studies on PTBD postdischarge extended care were identified in the CNKI, Wanfang, VIP, CBM, PubMed, Cochrane Library, Embase, Web of Science, and other databases. The quality of the included studies was evaluated using the Joanna Briggs Institute of Australia literature quality evaluation tool, and a meta-analysis of the included studies was performed with RevMan 5.4 software. RESULTS: Finally, 9 studies were included, with a total sample size of 854 patients (425 patients in the control group and 429 patients in the intervention group). Meta-analysis revealed that extended care effectively reduced biliary tract infection (RR: 0.42, 95%CI: 0.30-0.57), puncture wound infection (RR: 0.19, 95%CI: 0.06-0.65), catheter protrusion or displacement in discharged patients after PTBD (RR: 0.31, 95%CI: 0.18-0.54), catheter blockage (RR: 0.23, 95%CI: 0.13-0.42), skin infection around the drainage tube (RR: 0.30, 95%CI: 0.12-0.77), and catheter-related readmissions (RR: 0.34, 95%CI: 0.18-0.65) (P < 0.05). CONCLUSION: Compared with conventional discharge care, extended care can effectively reduce the occurrence of complications such as biliary tract infection, puncture wound infection, catheter prolapse or displacement, catheter blockage, skin infection around the drainage tube, and catheter-related readmission in discharged patients after PTBD.

Factors associated with neurofeedback and mindfulness-based combination therapy for patients with substance use disorder: A multicenter study

Background and objectives Substance use disorder (SUD) has become a major concern in public health globally, and there is an urgent need to develop an integrated psychosocial intervention. The aims of the current study are to test the efficacy of the integrated treatment with neurofeedback and mindfulness-based therapy for SUD and identify the predictors of the efficacy. Methods This study included 110 participants with SUD into the analysis. Outcome of measures includes demographic characteristics, severity of dependence, quality of life, symptoms of depression, and anxiety. Independent t test is used to estimate the change of scores at baseline and three months follow-up. Generalized estimating equations are applied to analyze the effect of predictors on the scores of dependence severity over time by controlling for the effects of demographic characteristics. Results A total of 22 (20 %) participants were comorbid with major mental disorder (MMD). The decrement of the severity in dependence, anxiety, and depression after treatment are identified. Improved scores of qualities of life in generic, psychological, social, and environmental domains are also noticed. After controlling for the effects of demographic characteristics, the predictors of poorer outcome are comorbid with MMD, lower quality of life, and higher level of depression and anxiety. Conclusion The present study implicates the efficacy of integrated therapy. Early identification of predictors is beneficial for healthcare workers to improve the treatment efficacy. (AU)

Comprehensive Analysis of N6-Methylandenosine-Related lncRNAs in Clear Cell Renal Cell Carcinoma: A Correlation With Prognosis, Tumor Progression, and Therapeutic Response.

This study aims to develop a prognostic signature based on m6A-related lncRNAs for clear cell renal cell carcinoma (ccRCC). Differential expression analysis and Pearson correlation analysis were used to identify m6A-related lncRNAs associated with patient outcomes in The Cancer Genome Atlas (TCGA) database. Our approach led to the development of an m6A-related lncRNA risk score (MRLrisk), formulated using six identified lncRNAs: NFE4, AL008729.2, AL139123.1, LINC02154, AC124854.1 and ARHGAP31-AS1. Higher MRLrisk was identified as a risk factor for patients' prognosis in ccRCC. Furthermore, an MRLrisk-based nomogram was developed and demonstrated as a reliable tool for prognosis prediction in ccRCC. Enrichment analysis and tumor mutation signature studies were conducted to investigate MRLrisk-related biological phenotypes. The tumor immune dysfunction and exclusion (TIDE) score was employed to infer patients' response to immunotherapy, indicating a negative correlation between high MRLrisk and immunotherapy response. Our focus then shifted to LINC02154 for deeper exploration. We assessed LINC02154 expression in 28 ccRCC/normal tissue pairs and 3 ccRCC cell lines through quantitative real-time polymerase chain reaction (qRT-PCR). Functional experiments, including EdU incorporation, flow cytometry and transwell assays, were performed to assess the role of LINC02154 in ccRCC cell functions, discovering that its downregulation hinders cancer cell proliferation and migration. Furthermore, the influence of LINC02154 on ccRCC cells' sensitivity to Sunitinib was explored using CCK-8 assays, demonstrating that decreased LINC02154 expression increases Sunitinib sensitivity. In summary, this study successfully developed an MRLrisk model with significant prognostic value for ccRCC and established LINC02154 as a critical biomarker and prospective therapeutic target in ccRCC management.

Genetic underpinnings explored: OPA1 deletion and complex phenotypes on chromosome 3q29.

BACKGROUND: Copy number variations (CNVs) have emerged as significant contributors to the elusive genetic causality of inherited eye diseases. In this study, we describe a case with optic atrophy and a brain aneurysm, in which a de novo CNV 3q29 deletion was identified. CASE PRESENTATION: A 40-year-old female patient was referred to our department after undergoing aneurysm transcatheter arterial embolization for a brain aneurysm. She had no history of systemic diseases, except for unsatisfactory best-corrected visual acuity (BCVA) since elementary school. Electrophysiological tests confirmed the findings in retinal images, indicating optic nerve atrophy. Chromosomal microarray analysis revealed a de novo deletion spanning 960 kb on chromosome 3q29, encompassing OPA1 and six neighboring genes. Unlike previously reported deletions in this region associated with optic atrophy, neuropsychiatric disorders, and obesity, this patient displayed a unique combination of optic atrophy and a brain aneurysm. However, there is no causal relationship between the brain aneurysm and the CNV. CONCLUSION: In conclusion, the optic atrophy is conclusively attributed to the OPA1 deletion, and the aneurysm could be a coincidental association. The report emphasizes the likelihood of underestimating OPA1 deletions due to sequencing technology limitations. Recognizing these constraints, healthcare professionals must acknowledge these limitations and consistently search for OPA1 variants/deletions in Autosomal Dominant Optic Atrophy (ADOA) patients with negative sequencing results. This strategic approach ensures a more comprehensive exploration of copy-number variations, ultimately enhancing diagnostic precision in the field of genetic disorders.

Microbial Analysis in Chronic Rhinosinusitis Patients with Chronic Kidney Disease and End-Stage Renal Disease.

INTRODUCTION: This study aimed to elucidate the bacterial profile of chronic rhinosinusitis (CRS) in patients with end-stage renal disease (ESRD) and chronic kidney disease (CKD) compared with nonrenal patients, guiding antibiotic selection for clinicians. METHODS: We retrospectively analyzed 13,906 inpatients from the Chang Gung Research Database who underwent sinus surgery (2004-2018). Patients were categorized into ESRD-CRS, CKD-CRS, and non-CKD-CRS based on the estimated glomerular filtration rate. Bacterial cultures from surgical samples were classified as facultative anaerobes or aerobes (e.g., Klebsiella pneumoniae [KP], Pseudomonas aeruginosa [Ps.a]), anaerobes, and fungi and ranked by prevalence. RESULTS: Data from 47 ESRD-CRS, 230 CKD-CRS, and 13,123 non-CKD-CRS patients were analyzed. In ESRD-CRS, the predominant species were KP (31.6%), Ps.a (21.1%), and Coagulase-negative Staphylococcus (CoNS, 15.8%). CKD-CRS showed Staphylococcus epidermidis (27.7%), CoNS (20.5%), and Ps.a (20.5%). Non-CKD-CRS had Staphylococcus epidermidis (29.8%), CoNS (25.0%), and Staphylococcus aureus (15.5%). For anaerobes, ESRD-CRS was dominated by Fusobacterium nucleatum (10.5%) and Peptostreptococcus micros (10.5%), whereas CKD-CRS and non-CKD-CRS showed Propionibacterium acnes as a primary strain (14.5% and 28.7%, respectively). CONCLUSION: For CRS in ESRD, antibiotics targeting KP and Fusobacterium nucleatum are recommended. In CKD-CRS, a focus on Staphylococcus epidermidis and Propionibacterium acnes is suggested. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:3499-3507, 2024.

Modified Ileal Conduit for Pelvic Lipomatosis: Technique Description and Outcome.

INTRODUCTION: To present the surgical technique and clinical outcomes of modified ileal conduit for pelvic lipomatosis (PL). METHODS: From 2020 to 2022, we prospectively enrolled 9 patients with PL undergoing modified ileal conduit. The patient characteristics, perioperative variables, and follow-up outcomes as well as the description of surgical technique were reported. RESULTS: All 9 patients successfully completed the operation. Two patients had perioperative complications of Clavien-Dindo grade I. The mean operation time and bleeding volumes were 253±51.4 min and 238.9±196.9 ml, with a mean postoperative follow-up time of 13.0±5.6 months. The postoperative 3-month and 1-year creatinine values were significantly decreased versus the preoperative (P=0.006 and P=0.024). The postoperative 3-month and 1-year eGFR values were significantly increased comapred with those before operation (P=0.0002 and P=0.018). The separation value of left renal pelvis collection system after operation were significantly reduced compared with preoperative evaluation (P=0.023 at 3 month and P=0.042 at 1 year) and so was the right side (P=0.019 and P=0.023). CONCLUSION: Modified ileal conduit is safe and feasible for PL. A large sample cohort with long-term follow-up is needed to evaluate the clinical outcomes of PL.

Data of RNA-seq transcriptomes of gastrocnemius muscle, epididymal adipose tissue in obese rats under normoxia/hypoxic exercise environments.

Studies on the crosstalk between muscle and adipose tissue can provide beneficial help in elucidating the pathogenesis and treatment of obesity-related diseases [1]. In this data article, we performed RNA sequence analysis of mRNA isolated from epididymal adipose tissue and gastrocnemius muscle tissue in obese rats. Twenty-two samples were selected for gene expression analysis. Raw data from the Illumina Hiseq™ platform sequencer was used for differential gene expression analysis using DESeq and deposited in the GEO public repository under accession number GSE237950. With the economic development and the change of people's lifestyle, obesity has become a major public health problem that endangers global health. Obesity is a metabolic disorder caused by excessive accumulation of white adipose tissue, which can further induce metabolic syndrome such as insulin resistance, type 2 diabetes, and cardiovascular and cerebrovascular diseases. Studies have shown that altitude hypoxic exercise can not only improve muscle buffering capacity and body performance, but also reduce body weight and body fat more significantly. In many countries, it has been used as a treatment program for obesity diseases [2]. Hypoxic exercise can improve lipid metabolism, reduce blood lipid levels, inhibit fatty acid synthesis, and promote fatty acid decomposition and oxidation, which is the mechanism of hypoxic exercise to significantly reduce weight and fat. However, the mechanism of the cross-talk between muscle and fat tissue is not well understood under hypoxia exercise and normoxia exercise conditions. The data contained rat's four different states: normoxia quiet, normoxia exercise, hypoxic quiet, and hypoxic exercise. RNA-seq data will provide insights into the cross-talk between muscle and fat, and the mechanisms of fat metabolism. The data of this study have not been published and are hereby published on this platform to study the cross talk between muscle tissue and adipose tissue in rats under different oxygen content and exercise environment.

Minimally invasive ureteroplasty with lingual mucosal graft for complex ureteral stricture: analysis of surgical and patient-reported outcomes

ABSTRACT Objective: To evaluate objective treatment efficacy and safety, and subjective patient-reported outcomes in patients with complex ureteral strictures (US) undergoing minimally invasive lingual mucosal graft ureteroplasty (LMGU). Materials and Methods: We prospectively enrolled patients underwent robotic or laparoscopic LMGU between May 2020 and July 2022. Clinical success was defined as symptom-free and no radiographic evidence of re-obstruction. Patient-reported outcomes, including health-related quality of life (HRQoL), mental health status and oral health-related quality of life (OHRQoL), were longitudinally evaluated before surgery, 6 and 12 months postoperatively. Results: Overall, 41 consecutive patients were included. All procedures were performed successfully with 32 patients in robotic approach and 9 in laparoscopic. Forty (97.56%) patients achieved clinical success during the median follow-up of 29 (range 15-41) months. Although patients with complex US experienced poor baseline HRQoL, there was a remarkable improvement following LMGU. Specifically, the 6-month and 12-month postoperative scores were significantly improved compared to the baseline (p < 0.05) in most domains. Twenty-eight (68.3%) and 31 (75.6%) patients had anxiety and depression symptoms before surgery, respectively. However, no significant decrease in the incidence of these symptoms was observed postoperatively. Moreover, there was no significant deterioration of OHRQoL at 6 months and 12 months postoperatively when compared to the baseline. Conclusions: LMGU is a safe and efficient procedure for complex ureteral reconstruction that significantly improves patient-reported HRQoL without compromising OHRQoL. Assessing patients' quality of life enables us to monitor postoperative recovery and progress, which should be considered as one of the criteria for surgical success.

Characteristic of school injuries in Asia: a cross-national, multi-center observational study.

BACKGROUND: To prevent school injuries, thorough epidemiological data is an essential foundation. We aimed to investigate the characteristics of school injuries in Asia and explore risk factors for major trauma. METHODS: This retrospective study was conducted in the participating centers of the Pan-Asian Trauma Outcome Study from October 2015 to December 2020. Subjects who reported "school" as the site of injury were included. Major trauma was defined as an Injury Severity Score (ISS) value of ≥16. RESULTS: In total, 1305 injury cases (1.0% of 127,715 events) occurred at schools. Among these, 68.2% were children. Unintentional injuries were the leading cause and intentional injuries comprised 7.5% of the cohort. Major trauma accounted for 7.1% of those with documented ISS values. Multivariable regression revealed associations between major trauma and factors, including age, intention of injury (self-harm), type of injury (traffic injuries, falls), and body part injured (head, thorax, and abdomen). Twenty-two (1.7%) died, with six deaths related to self-harm. Females represented 28.4% of injuries but accounted for 40.9% of all deaths. CONCLUSIONS: In Asia, injuries at schools affect a significant number of children. Although the incidence of injuries was higher in males, self-inflicted injuries and mortality cases were relatively higher in females. IMPACT: Epidemiological data and risk factors for major trauma resulting from school injuries in Asia are lacking. This study identified significant risk factors for major trauma occurring at schools, including age, intention of injury (self-harm), injury type (traffic injuries, falls), and body part injured (head, thoracic, and abdominal injuries). Although the incidence of injuries was higher in males, the incidence of self-harm injuries and mortality rates were higher in females. The results of this would make a significant contribution to the development of prevention strategies and relative policies concerning school injuries.

Impaired Brain-Heart Relation in Patients With Methamphetamine Use Disorder During VR Induction of Drug Cue Reactivity.

Methamphetamine use disorder (MUD) is an illness associated with severe health consequences. Virtual reality (VR) is used to induce the drug-cue reactivity and significant EEG and ECG abnormalities were found in MUD patients. However, whether a link exists between EEG and ECG abnormalities in patients with MUD during exposure to drug cues remains unknown. This is important from the therapeutic viewpoint because different treatment strategies may be applied when EEG abnormalities and ECG irregularities are complications of MUD. We designed a VR system with drug cues and EEG and ECG were recorded during VR exposure. Sixteen patients with MUD and sixteen healthy subjects were recruited. Statistical tests and Pearson correlation were employed to analyze the EEG and ECG. The results showed that, during VR induction, the patients with MUD but not healthy controls showed significant [Formula: see text] and [Formula: see text] power increases when the stimulus materials were most intense. This finding indicated that the stimuli are indiscriminate to healthy controls but meaningful to patients with MUD. Five heart rate variability (HRV) indexes significantly differed between patients and controls, suggesting abnormalities in the reaction of patient's autonomic nervous system. Importantly, significant relations between EEG and HRV indexes changes were only identified in the controls, but not in MUD patients, signifying a disruption of brain-heart relations in patients. Our findings of stimulus-specific EEG changes and the impaired brain-heart relations in patients with MUD shed light on the understanding of drug-cue reactivity and may be used to design diagnostic and/or therapeutic strategies for MUD.

Efficacy and Safety of Direct Oral Anticoagulants in Pediatric Venous Thromboembolism: A Systematic Review and Meta-Analysis.

OBJECTIVES: To assess the efficacy and safety of direct oral anticoagulants (DOACs) in comparison to standard-of-care (SOC) anticoagulants in the management and prophylaxis of thromboembolic events in pediatric populations. METHODS: A comprehensive search of electronic databases was conducted to identify relevant studies published between January 1, 2015, and December 18, 2022. A meta-analysis was undertaken to evaluate the effect of DOACs on clinically significant endpoints, employing trial-level data with harmonized endpoint definitions. The primary outcome was venous thromboembolism (VTE). Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. The study was registered with INPLASY (2022120065). RESULTS: Three studies encompassing 934 subjects were included. The incidence of VTE was reduced in patients administered DOACs compared to those on SOC anticoagulants (OR 0.41 [95% CI 0.19-0.93], I² = 0%, P = 0.03). No significant differences were observed between the DOAC and SOC groups in all-cause mortality (OR 0.50 [95% CI 0.07-3.59], I² = 0%, P = 0.35) or serious adverse events (OR 0.75 [95% CI 0.50-1.12], I² = 0%, P = 0.16). The risk of major bleeding (OR 0.50 [95% CI 0.13-1.87], I² = 44%, P = 0.30) and clinically relevant non-major bleeding (OR 1.23 [95% CI 0.50-3.00], I² = 0%, P = 0.65) exhibited no significant differences between the groups. CONCLUSIONS: DOACs are associated with a reduced risk of VTE in pediatric patients without increasing the risk of bleeding, all-cause mortality, or serious adverse events when compared to SOC anticoagulants. DOACs may be an alternative for the treatment and prevention of thromboembolic events in the pediatrics.

Clinical Characteristics and Genetic Variants in Taiwanese Patients With PROM1-Related Inherited Retinal Disorders.

Purpose: This study investigated the clinical characteristics of patients with PROM1-related inherited retinal diseases (IRDs). Methods: Patients diagnosed with IRDs who had mutations in PROM1 were identified at Linkou Chang Gung Memorial Hospital and Kaohsiung Medical University Hospital in Taiwan. Information on clinical characteristics and best-corrected visual acuity was recorded. Color fundus (CF) images, fundus autofluorescence photography (FAF), spectral-domain optical coherence tomography (SD-OCT), and electroretinograms (ERGs) were analyzed to examine patient phenotypes. PROM1 variants were detected using whole exome sequencing and verified by Sanger sequencing. Results: Fourteen patients from nine families with PROM1-related IRDs were analyzed. Most patients exhibited chorioretinal atrophy in the macular area, with or without extramacular involvement on CF. Similarly, hypo-autofluorescence confined to the macular area, with or without extramacular involvement, was present for most patients on FAF. Furthermore, SD-OCT revealed outer retinal tubulations and focal or diffuse retinal thinning. ERGs showed variable findings, including maculopathy with normal ERG, subnormal cone response, and extinguished rod and cone responses. We detected five variants of the PROM1 gene, including c.139del, c.794del, c.1238T>A, c.2110C>T, and c.1117C>T. Conclusions: In this study, we evaluated 14 Taiwanese patients with five PROM1 variants. Additionally, incomplete penetrance of heterozygous PROM1 variants was observed. Furthermore, patients with autosomal dominant PROM1 variants had lesions in the macular area and the peripheral region of the retina. SD-OCT serves as a useful tool for early detection of PROM1-related IRDs, as it captures certain signs of such diseases.

Efficacy and safety of baricitinib for the treatment of hospitalized adults with COVID-19: a systematic review and meta-analysis.

OBJECTIVES: Several clinical trials have evaluated the efficacy and safety of baricitinib in COVID-19 patients. Recently, there have been reports on critical patients, which are different from previous research results. The meta-analysis was performed to investigate the effects of baricitinib in COVID-19, by pooling data from all clinically randomized controlled trials (RCTs) available to increase power to testify. METHODS: Studies were searched in PubMed, Embase, and Cochrane Library databases on January 31, 2023. We performed a meta-analysis to estimate the efficacy and safety of baricitinib for the treatment of hospitalized adults with COVID-19. This study is registered with INPLASY, number 202310086. RESULTS: A total of 3010 patients were included in our analyses. All included studies were randomized controlled trials or prospective study. There was no difference in 14-day mortality between the two groups [OR 0.23 (95% CI 0.03-1.84), I2 = 72%, P = 0.17]. In subgroup analyses we found that baricitinib did not seem to improve significantly in 24-day mortality critically ill patients [OR 0.60 (95% CI 0.35-1.02), I2 = 0%, P = 0.06]. Fortunately, baricitinib have led to faster recovery and shorter hospital stays for COVID-19 patients. There were no difference in infections and infestations, major adverse cardiovascular events, deep vein thrombosis and pulmonary embolism. CONCLUSIONS: Baricitinib did not increase the incidence of adverse reactions. At the same time, we can find that it reduces the mortality of COVID-19 patients, not including the critically ill.

Aspirin versus LMWH for VTE prophylaxis after orthopedic surgery.

Low molecular weight heparin (LMWH) is often used to prevent perioperative venous thrombosis after surgery, but aspirin is also recommended by academics. Studies were searched in electronic databases until February 24, 2023. We performed a meta-analysis to evaluate the safety and efficacy of aspirin and LMWH for venous thromboembolism (VTE) prophylaxis in patients after orthopedic surgery. The outcomes were death from any causes, deep vein thrombosis (DVT), pulmonary embolism (PE), etc. This study was registered with INPLASY, number 202320117. Six randomized controlled trials enrolled 13,851 patients with postoperative joint surgery. The risk of DVT was comparable between the two groups when aspirin was combined with mechanical devices (RR 0.61 [95% CI 0.27-1.39], I² = 62%, P = 0.24). No significant differences in all cause death, PE, wound infection, and wound complication were found between the aspirin and LMWH groups. In this meta-analysis, the mortality rate was comparable between the aspirin and LMWH groups. However, aspirin alone had a higher risk of DVT than LMWH. Based on the results of this meta-analysis, we suggest aspirin combined with mechanical devices for VTE prophylaxis in patients after orthopedic surgery.

Surgical techniques and oncological outcomes of pure transperitoneal laparoscopic radical nephroureterectomy for upper urinary tract urothelial carcinoma.

Background: Open radical nephroureterectomy (RNU) with bladder cuff excision is the standard treatment for upper urinary tract urothelial carcinoma (UTUC). Traditional laparoscopic radical nephroureterectomy (LSRNU) is not minimally invasive enough due to the complex surgical procedure. This study aims to discuss the clinical feasibility and oncological outcomes of pure transperitoneal LSRNU for UTUC. Methods: Between July 2010 and December 2020, 115 patients were admitted to the hospital with the diagnosis of UTUC treated with pure LSRNU by one surgeon. A special laparoscopic bulldog clamp was placed at the bladder cuff before cutting and suturing. The clinical and follow-up data were preoperatively collected and analyzed. Overall survival (OS) and cancer-specific survival (CSS) were estimated by the Kaplan-Meier method. Results: All surgeries were completed uneventfully in this cohort. The mean operative time was 145.69 minutes. The mean estimated blood loss was 56.61 mL. The mean removal time of the drain was 3.46 days. The mean time of having liquid diet was 1.32 days, and the ambulation time was 1.50 days. All surgeries were effectively completed, and no case required open conversion. According to the Clavien-Dindo classification system, postoperative complications occurred in two patients (II, III). The mean length of postoperative hospital stay was 5.78 days. The mean follow-up duration was 54.50 months. Recurrence in the bladder was 16.0% (15/94), compared with 4.6% (4/87) in the contralateral upper tract. The 5-year OS and CSS rates were 78.9% and 81.4%, respectively. Conclusions: Pure transperitoneal LSRNU is a safe and effective minimally invasive technology for the treatment of UTUC.

Circular RNA_0000326 accelerates breast cancer development via modulation of the miR-9-3p/YAP1 axis.

Circular RNA (circ)_0000326 has been reported in bladder cancer and cervical cancer and is concerned to be involved with the development of cancerous cells. Whereas, there have been no reports concentrating on the influences of circ_0000326 in breast cancer (BC). Therefore, the latent modulatory mechanisms of circ_0000326 in BC are researched. circ_0000326 expression in BC tissues and correlative cells was evaluated via RT-qPCR, and the relevance between circ_0000326 expression and overall survival and the clinicopathological feature was also investigated. After a series of transfection, the effects of circ_0000326, microRNA-9-3p (miR-9-3p), and Yes-associated protein 1 (YAP1) in BC cell growth, invasion, and stemness were studied by CCK-8, flow cytometry, Transwell, and sphere-forming assays. The binding sites and correlation of circ_0000326, miR-9-3p, and YAP1 were certified via starBase website, luciferase reporter assay, and Pearson's χ2 test. The in vivo experiment was evaluated by establishing a subcutaneous tumorigenesis model. High-expressed circ_0000326 in BC tissues and cells was discovered, which was connected with an undesirable prognosis. Silencing of circ_0000326 visibly inhibited MCF-7 and BT549 cell growth, invasion, stemness, meanwhile declining the protein levels of SRY-related high-mobility group box gene 2 (SOX2) and octamer binding transcription factor 4 (OCT4). miR-9-3p was a sponger of circ_0000326, which was negatively regulated by circ_0000326. Moreover, YAP1 was confirmed as a target gene of miR-9-3p. circ_0000326 affected BC cell behaviors via mediating miR-9-3p and YAP1. Furthermore, circ_0000326 silencing prohibited tumor growth of BC in vivo. The research uncovered that circ_0000326 facilitated BC development via mediating the miR-9-3p/YAP1 axis.
