Impact of fast-track surgery-oriented care pathways on perioperative rehabilitation indices in patients undergoing radical prostatectomy for prostate cancer.

OBJECTIVE: This study was conducted to evaluate the effects of Fast-Track Surgery (FTS)-oriented care pathways on perioperative rehabilitation indicators in patients undergoing radical prostatectomy for prostate cancer. METHODS: The clinical data of 120 patients admitted to Sichuan Cancer Hospital & Institute who underwent radical prostatectomy for prostate cancer from September 2020 to October 2022 were collected and retrospectively analyzed. The patients were divided into a control group (n=60, receiving standard care) and an FTS group (n=60 patients receiving FTS-oriented care) according to different nursing methods. The perioperative rehabilitation indices were compared between the groups. RESULTS: The FTS group exhibited shorter hospitalization duration (P=0.001), postoperative anal exhaust time (P=0.012), drain removal time (P=0.007), gastrointestinal recovery time (P=0.008), and a lower total complication rate (P=0.016) compared to the control group. The scores of Visual Analog Scale (VAS) (P=0.001, P=0.003, P=0.015) and Activities of Daily Living (ADL) (P=0.011, P=0.005, P=0.007) at 24, 48, and 72 hours postoperatively were significantly lower in the FTS group than in the control group. Hospitalization cost (P=0.002) and medication expenses (P=0.016) were notably lower in the FTS group. During a 12-month follow-up, the FTS group showed a significantly lower complication rates (3.33%) compared to the control group (18.33%) (P=0.009). CONCLUSION: The application of FTS-oriented nursing pathway in patients undergoing radical prostatectomy for prostate cancer significantly enhances postoperative rehabilitation, reduces pain, lowers hospitalization and medication costs, and improves postoperative quality of life, which contributes positively to the nurse-patient relationship and patient outcome.

Jingangteng capsules ameliorate liver lipid disorders in diabetic rats by regulating microflora imbalances, metabolic disorders, and farnesoid X receptor.

BACKGROUND: The plant Smilax china L., also known as Jingangteng, is suspected of regulating glucose and lipid metabolism. Jingangteng capsules (JGTCs) are commonly used to treat gynecological inflammation in clinical practice. However, it is not clear whether JGTCs can regulate glucose and lipid metabolism, and the mechanism is unclear. PURPOSE: To investigate the impact and mechanism of action of JGTCs on diabetes and liver lipid disorders in rats. METHODS: The chemical constituents of JGTCs were examined using ultra-high-performance liquid chromatography with quadrupole time-of-flight mass spectrometry. A high-fat diet and streptozotocin-induced diabetes model was used to evaluate anti-diabetic effects by assessing blood glucose and lipid levels and liver function. The mechanism was explored using fecal 16S rRNA gene sequencing and metabolomics profiling, reverse transcription-quantiative polymerase chain reaction (RT-qPCR), and Western blot analysis. RESULTS: Thirty-three components were identified in JGTCs. The serological and histomorphological assays revealed that JGTC treatment reduced levels of blood glucose and lipids, aspartate aminotransferase, alanine aminotransferase, and lipid accumulation in the liver of diabetic rats. According to 16S rDNA sequencing, JGTCs improved species richness and diversity in diabetic rats' intestinal flora and restored 22 dysregulated bacteria to control levels. Fecal metabolomics analysis showed that the altered fecal metabolites were rich in metabolites, such as histidine, taurine, low taurine, tryptophan, glycerophospholipid, and arginine. Serum metabolomics analysis indicated that serum metabolites were enriched in the metabolism of glycerophospholipids, fructose and mannose, galactose, linoleic acid, sphingolipids, histidine, valine, leucine and isoleucine biosynthesis, and tryptophan metabolism. Heatmaps revealed a strong correlation between metabolic parameters and gut microbial phylotypes. Molecular biology assays showed that JGTC treatment reversed the decreased expression of farnesoid X receptor (FXR) in the liver of diabetic rats and inhibited the expression of lipogenic genes (Srebp1c and FAS) as well as inflammation-related genes (interleukin (IL)-ß, tumor necrosis factor (TNF)-α, and IL-6). Liver metabolomics analysis indicated that JGTC could significantly regulate a significant number of bile acid metabolites associated with FXR, such as glyco-beta-muricholic acid, glycocholic acid, tauro-beta-muricholic acid, and tauro-gamma-muricholic acid. CONCLUSIONS: This was the first study to investigate the mechanisms of JGTCs' effects on liver lipid disorders in diabetic rats. JGTCs inhibited liver lipid accumulation and inflammatory responses in diabetic rats by affecting intestinal flora and metabolic disorders and regulating FXR-fat synthesis-related pathways to alleviate diabetic lipid disorders.

The trends of pediatric duodenal ulcer and predictors of recurrence.

BACKGROUND: Duodenal ulcer (DU) causes various symptoms in children. The prevalence of Helicobacter pylori (Hp)-associated DU has been reducing in some regions, yet the updated trend in Taiwan is unknown. Risk factors of DU recurrence have not been comprehensively investigated in children. METHODS: This retrospective study included children diagnosed with DU to evaluate the demographics, symptoms, diagnostics, treatment, and outcomes. Specific populations (infant, surgery required) were sorted for subgroup analysis. Predictors of DU recurrence was analyzed in patients who received endoscopic follow-ups. RESULTS: A total of 488 children were included. Most patients were male (72.5%), school-aged (11.3 ± 4.8 years old), and with varied underlying diseases in one-fifth. The annual incidences were around 3-5%, with a declining trend of case numbers and the Hp-positive proportion. Hp infection, concurrent gastric ulcer, perforation, and mortality were noted in 32.7%, 16%, 1.6%, and 1% of patients. Patients with or without Hp infection showed different clinical features but similar outcomes. The characteristics of subpopulations were depicted respectively. Male sex, lower Hb level, and perforation were independent risk factors associated with recurrence. CONCLUSIONS: Hp-positive DU seems to wane. Patients with male sex, lower Hb level, or perforation at diagnosis carried a higher risk of recurrence, which may warrant active surveillance and endoscopic follow-up.

Upstream stimulating factor 2 aggravates neuropathic pain induced in spinal nerve ligation-induced mice via regulating SNHG5/miR-181b-5p.

BACKGROUND: Upstream stimulating factor 2 (USF2) belongs to basic-Helix-Loop-Helix-Leucine Zipper transcription factor family, regulating expression of genes involved in immune response or energy metabolism network. Role of USF2 in neuropathic pain was evaluated. METHODS: Mice were intraspinally injected with adenovirus for knockdown of USF2 (Ad-shUSF2), and then subjected to spinal nerve ligation (SNL) to induce neuropathic pain. Distribution and expression of USF2 was detected by western blot and immunofluorescence. Mechanical and thermal pain sensitivity were examined by paw withdrawal thresholds (PWT) and paw withdrawal latency (PWL). Chromatin immunoprecipitation (ChIP) and luciferase activity assays were performed to detect binding ability between USF2 and SNHG5. RESULTS: The expression of USF2 was elevated and colocalized with astrocytes and microglia in L5 dorsal root ganglion (DRG) of SNL-induced mice. Injection of Ad-shUSF2 attenuated SNL-induced decrease of PWT and PWL in mice. Knockdown of USF2 increased level of IL-10, but decreased TNF-α, IL-1ß, and IL-6 in SNL-induced mice. Silence of USF2 enhanced protein expression of CD206, while reduced expression of CD16 and CD32 in SNL-induced mice. USF2 bind to promoter of SNHG5, and weakened SNL-induced up-regulation of SNHG5. SNHG5 bind to miR-181b-5p, and miR-181b-5p to interact with CXCL5. CONCLUSION: Silence of USF2 ameliorated neuropathic pain, suppressed activation of M1 microglia and inhibited inflammation in SNL-induced mice through regulation of SNHG5/miR-181b-5p/CXCL5 axis. Therefore, USF2/SNHG5/miR-181b-5p/CXCL5 might be a promising target for neuropathic pain. However, the effect of USF2/SNHG5/miR-181b-5p/CXCL5 on neuropathic pain should also be investigated in further research.

An immunophenotype-coupled transcriptomic atlas of human hematopoietic progenitors.

Analysis of the human hematopoietic progenitor compartment is being transformed by single-cell multimodal approaches. Cellular indexing of transcriptomes and epitopes by sequencing (CITE-seq) enables coupled surface protein and transcriptome profiling, thereby revealing genomic programs underlying progenitor states. To perform CITE-seq systematically on primary human bone marrow cells, we used titrations with 266 CITE-seq antibodies (antibody-derived tags) and machine learning to optimize a panel of 132 antibodies. Multimodal analysis resolved >80 stem, progenitor, immune, stromal and transitional cells defined by distinctive surface markers and transcriptomes. This dataset enables flow cytometry solutions for in silico-predicted cell states and identifies dozens of cell surface markers consistently detected across donors spanning race and sex. Finally, aligning annotations from this atlas, we nominate normal marrow equivalents for acute myeloid leukemia stem cell populations that differ in clinical response. This atlas serves as an advanced digital resource for hematopoietic progenitor analyses in human health and disease.

Serum iron concentration and leptin inversely relate, partially mediated by body mass index in American adults.

Iron metabolism and leptin are interconnected, and both link with obesity. In this cross-sectional study, we hypothesized that serum iron markers associate with leptin, with body mass index (BMI) acting as a mediator, confounder, and effect modifier in this relationship. We analyzed data from the National Health and Nutrition Examination Survey III, with a focus on serum iron markers and leptin. The relationship between serum iron markers and leptin was determined by multiple linear regression. The bootstrap method was used to investigate the mediating effect of BMI on this association. Among 3888 American adults, serum iron and transferrin saturation showed a negative association with leptin (log2-transformed) (ß: -0.010, 95% confidence interval [CI], -0.013 to -0.006, P < .001; ß: -0.006, 95% CI, -0.008 to -0.004, P < .001). Total iron-binding capacity was positively associated with the serum concentration of leptin (log2-transformed) (ß: 0.002, 95% CI, 0-0.004, P = .0292). Sex, BMI, and body fat percentage significantly influenced these associations. Notably, the association between the iron markers and leptin diminished in individuals with a BMI ≥30 kg/m2. There was no observable relationship between leptin and serum ferritin concentrations. BMI mediated 4.81% of the serum iron-leptin association, with no mediation of body fat percentage. Our study identified a link between serum iron and leptin, with BMI as a mediating factor. In clinical settings, it is vital to understand how treatments targeting iron metabolism can directly impact serum leptin concentration and the subsequent physiological changes.

Circ ubiquitin-like-containing plant homeodomain and RING finger domains protein 1 increases the stability of G9a and ubiquitin-like-containing plant homeodomain and RING finger domains protein 1 messenger RNA through recruiting eukaryotic translation initiation factor 4A3, transcriptionally inhibiting PDZ and homeobox protein domain protein 1, and promotes the metastasis of hepatocellular carcinoma.

BACKGROUND AND AIM: Circular ubiquitin-like, containing PHD and ring finger domains 1 (circUHRF1) is aberrantly upregulated in human hepatocellular carcinoma (HCC) tissues. However, the underlying molecular mechanisms remain obscure. The present study aimed at elucidating the interactive function of circUHRF1-G9a-ubiquitin-like, containing PHD and ring finger domains 1 (UHRF1) mRNA-eukaryotic translation initiation factor 4A3 (EIF4A3)-PDZ and LIM domain 1 (PDLIM1) network in HCC. METHODS: Expression of circUHRF1, mRNAs of G9a, UHRF1, PDLIM1, epithelial-mesenchymal transition (EMT)-related proteins, and Hippo-Yap pathway components was determined by quantitative polymerase chain reaction (Q-PCR), immunofluorescence, or Western blot analysis. Tumorigenic and metastatic capacities of HCC cells were examined by cellular assays including Cell Counting Kit-8, colony formation, wound healing, and transwell assays. Molecular interactions between EIF4A3 and UHRF1 mRNA were detected by RNA pull-down experiment. Complex formation between UHRF1 and PDLIM1 promoter was detected by chromatin immunoprecipitation assay. Co-immunoprecipitation was performed to examine the binding between UHRF1 and G9a. RESULTS: Circular ubiquitin-like, containing PHD and ring finger domains 1, G9a, and UHRF1 were upregulated, while PDLIM1 was downregulated in HCC tissue samples and cell lines. Cellular silencing of circUHRF1 repressed HCC proliferation, invasion, migration, and EMT. G9a formed a complex with UHRF1 and inhibited PDLIM1 transcription. CONCLUSION: Eukaryotic translation initiation factor 4A3 regulated circUHRF1 expression by binding to UHRF1 mRNA promoter. circUHRF1 increased the stability of G9a and UHRF1 mRNAs through recruiting EIF4A3. Overexpression of circUHRF1 aggravated HCC progression through Hippo-Yap pathway and PDLIM1 inhibition. By elucidating the molecular function of circUHRF1-G9a-UHRF1 mRNA-EIF4A3-PDLIM1 network, our data shed light on the HCC pathogenesis and suggest a novel therapeutic strategy for future HCC treatment.

Circ_0001982 aggravates breast cancer development through the circ_0001982-miR-144-3p-GSE1 axis.

This study was designed to explore the role of circ_0001982 in breast cancer (BC) development. Quantitative real-time polymerase chain reaction and western blot analysis assays were used to determine circ_0001982, miR-144-3p, and gse1 coiled-coil protein (GSE1) expression. Functional assays were performed to evaluate cell proliferation, apoptosis, migration, and invasion. The glycolysis was analyzed with commercial kits. Dual-luciferase reporter assay and RNA immunoprecipitation assays were conducted to analyze the relationships among circ_0001982, miR-144-3p, and GSE1. A murine xenograft model assay was performed to determine circ_0001982-induced effects on BC cell tumor properties in vivo. Circ_0001982 expression was upregulated, but miR-144-3p was reduced in BC tissues and cells in comparison with normal breast tissues and normal human mammary epithelial cells. Circ_0001982 knockdown or miR-144-3p overexpression inhibited BC cell proliferation, glycolysis, migration and invasion, and promoted apoptosis. Circ_0001982 sponged miR-144-3p and negatively regulated miR-144-3p expression in BC cells. In addition, GSE1 was identified as a target mRNA of miR-144-3p. Ectopic GSE1 expression relieved circ_0001982 depletion-induced effects on BC cell tumor properties. Furthermore, circ_0001982 absence suppressed BC cell tumor properties in vivo. Circ_0001982 contributed to the BC cell tumor properties by regulating the miR-144-3p-GSE1 axis.

Cardiorespiratory fitness and morbidity and mortality in patients with non-small cell lung cancer: a prospective study with propensity score weighting.

INTRODUCTION: This study aimed to investigate the association between cardiorespiratory fitness (CRF) and perioperative morbidity and long-term mortality in operable patients with early-stage non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: This prospective study included consecutive patients with early-stage NSCLC who underwent presurgical cardiopulmonary exercise testing between November 2014 and December 2019 (registration number: ChiCTR2100048120). Logistic and Cox proportional hazards regression were applied to evaluate the correlation between CRF and perioperative complications and long-term mortality, respectively. Propensity score overlap weighting was used to adjust for the covariates. We performed sensitivity analyses to determine the stability of our results. RESULTS: A total of 895 patients were followed for a median of 40 months [interquartile range 25]. The median age of the patients was 59 years [range 26-83], and 62.5% were male. During the study period, 156 perioperative complications and 146 deaths were observed. Low CRF was associated with a higher risk of death (62.9 versus 33.6 per 1000 person-years; weighted incidence rate difference, 29.34 [95% CI, 0.32 to 58.36] per 1000 person-years) and perioperative morbidity (241.6 versus 141.9 per 1000 surgeries; weighted incidence rate difference, 99.72 [95% CI, 34.75 to 164.70] per 1000 surgeries). A CRF of ≤ 20 ml/kg/min was significantly associated with a high risk of long-term mortality (weighted hazard ratio, 1.98 [95% CI, 1.31 to 2.98], p < 0.001) and perioperative morbidity (weighted odds ratio, 1.93 [1.28 to 2.90], p = 0.002) compared to higher CRF. CONCLUSION: The study found that low CRF is significantly associated with increased perioperative morbidity and long-term mortality in operable patients with early-stage NSCLC.

Low cardiorespiratory fitness is significantly associated with increased perioperative morbidity and long-term mortality in operable patients with early-stage non-small cell lung cancer.Future research is recommended to investigate the potential prognostic role of integrating cardiorespiratory fitness into the currently used prognosis algorithm for patients with non-small cell lung cancer.

Prognostic models for predicting overall and cancer-specific survival of patients with initially diagnosed metastatic cervical squamous cell carcinoma: A study based on SEER database.

Cervical squamous cell carcinoma (CSCC) is the most common histological type of cervical cancer (CC). And mCSCC is the end stage of CSCC. The aim of this study was to develop prognostic nomograms that provide better predictions for overall survival (OS) and cancer-specific survival (CSS) in mCSCC patients. Data from patients with initially diagnosed mCSCC were extracted from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2015. The nomograms for OS and CSS were constructed based on Cox regression analysis. The validation of the newly established nomograms was evaluated by concordance index (C-index), calibration curves, and decision curve analyses (DCAs). A total of 2198 patients with mCSCC were included and randomly split into training (n = 1539) and validation (n = 659) cohorts in a 7:3 ratio. Multivariate analyses revealed that the prognostic variables significantly related to the OS and CSS were marital status, T stage, brain metastasis, lung metastasis, tumor size, number of positive lymph nodes, chemotherapy, and radiotherapy. The nomograms were constructed based on these factors. The C-index value of the nomograms for predicting OS and CSS was 0.714 and 0.683, respectively. The calibration curves of the nomograms showed good consistency between nomogram prediction and actual survival for both OS and CSS, and the DCAs showed great clinical usefulness of the nomograms. The mCSCC patients were classified into low- and high-risk groups based on the scores from the nomograms. In the validation cohort, mCSCC patients with low-risk had much higher OS and CSS than those with high-risk. We constructed nomograms for predicting the OS and CSS of patients with initially diagnosed mCSCC. Our models had satisfactory predictive performance and could be useful in survival prediction for mCSCC.

Energy and Infrared Radiation Characteristics of the Sandstone Damage Evolution Process.

The mechanical characteristics and mechanisms of rock failure involve complex rock mass mechanics problems involving parameters such as energy concentration, storage, dissipation, and release. Therefore, it is important to select appropriate monitoring technologies to carry out relevant research. Fortunately, infrared thermal imaging monitoring technology has obvious advantages in the experimental study of rock failure processes and energy dissipation and release characteristics under load damage. Therefore, it is necessary to establish the theoretical relationship between the strain energy and infrared radiation information of sandstone and to reveal its fracture energy dissipation and disaster mechanism. In this study, an MTS electro-hydraulic servo press was used to carry out uniaxial loading experiments on sandstone. The characteristics of dissipated energy, elastic energy, and infrared radiation during the damage process of sandstone were studied using infrared thermal imaging technology. The results show that (1) the transition of sandstone loading from one stable state to another occurs in the form of an abrupt change. This sudden change is characterized by the simultaneous occurrence of elastic energy release, dissipative energy surging, and infrared radiation count (IRC) surging, and it has the characteristics of a short duration and large amplitude variation. (2) With the increase in the elastic energy variation, the surge in the IRC of sandstone samples presents three different development stages, namely fluctuation (stage Ⅰ), steady rise (stage Ⅱ), and rapid rise (stage Ⅲ). (3) The more obvious the surge in the IRC, the greater the degree of local damage of the sandstone and the greater the range of the corresponding elastic energy change (or dissipation energy change). (4) A method of sandstone microcrack location and propagation pattern recognition based on infrared thermal imaging technology is proposed. This method can dynamically generate the distribution nephograph of tension-shear microcracks of the bearing rock and accurately evaluate the real-time process of rock damage evolution. Finally, this study can provide a theoretical basis for rock stability, safety monitoring, and early warning.

Blockage of ATPase-mediated energy supply inducing metabolic disturbances in algal cells under silver nanoparticles stress.

Adenosine triphosphate (ATP) generation of aquatic organisms is often subject to nanoparticles (NPs) stress, involving extensive reprogramming of gene expression and changes in enzyme activity accompanied by metabolic disturbances. However, little is known about the mechanism of energy supply by ATP to regulate the metabolism of aquatic organisms under NPs stress. Here, we selected extensively existing silver nanoparticles (AgNPs) to investigate their implications on ATP generation and relevant metabolic pathways in alga (Chlorella vulgaris). Results showed that ATP content significantly decreased by 94.2% of the control (without AgNPs) in the algal cells at 0.20 mg/L AgNPs, which was mainly attributed to the reduction of chloroplast ATPase activity (81.4%) and the downregulation of ATPase-coding genes atpB and atpH (74.5%-82.8%) in chloroplast. Molecular dynamics simulations demonstrated that AgNPs competed with the binding sites of substrates adenosine diphosphate and inorganic phosphate by forming a stable complex with ATPase subunit beta, potentially resulting in the reduced binding efficiency of substrates. Furthermore, metabolomics analysis proved that the ATP content positively correlated with the content of most differential metabolites such as D-talose, myo-inositol, and L-allothreonine. AgNPs remarkably inhibited ATP-involving metabolic pathways, including inositol phosphate metabolism, phosphatidylinositol signaling system, glycerophospholipid metabolism, aminoacyl-tRNA biosynthesis, and glutathione metabolism. These results could provide a deep understanding of energy supply in regulating metabolic disturbances under NPs stress.

Discovery of Paltusotine (CRN00808), a Potent, Selective, and Orally Bioavailable Non-peptide SST2 Agonist.

The discovery of a novel 4-(4-aminopiperidinyl)-3,6-diarylquinoline series of potent SST2 agonists is described. This class of molecules exhibit excellent selectivity over SST1, SST3, SST4, and SST5 receptors. The compound 3-[4-(4-aminopiperidin-1-yl)-3-(3,5-difluorophenyl)quinolin-6-yl]-2-hydroxybenzonitrile (22, paltusotine, formerly known as CRN00808) showed no direct inhibition of major cytochrome P450 enzymes or the hERG ion channel and had sufficient exposure in rats and excellent exposure in dogs upon oral dosing. In pharmacodynamic studies, compound 22 dose-dependently suppressed growth hormone (GH) secretion induced by an exogenous growth-hormone-releasing hormone (GHRH) challenge in both male and female rats following a single oral dose and suppressed IGF-1 levels with repeated oral administration in both rats and dogs. To the best of our knowledge, compound 22 is the first non-peptide SST2 agonist to advance to human clinical trials and is currently in Phase 3 trials in acromegaly patients and a Phase 2 trial in neuroendocrine tumor patients suffering from carcinoid syndrome.

MiR-30c facilitates natural killer cell cytotoxicity to lung cancer through targeting GALNT7.

BACKGROUND: MicroRNAs (miRNAs) have been reported to play important roles in regulating natural killer (NK) cell cytotoxicity to cancer cells. OBJECTIVE: This study aimed to investigate the effects and potential mechanism of miR-30c in regulating NK cell cytotoxicity to lung cancer cells. METHODS: Primary NK cells were derived from the peripheral blood of lung cancer and normal participants. Exosomes were isolated and validated via transmission electron microscopy and nanoparticle tracking analysis. The levels of miR-30c, polypeptide N-acetylgalactosaminyltransferase 7 (GALNT7) and proteins in PI3K/AKT pathway were determined using quantitative real-time polymerase chain reaction or western blot. Tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ) levels and the cytotoxicity of effector NK cells to target lung cancer cells were measured via enzyme linked immunosorbent assay, cell apoptosis or xenograft experiments. The relationship between miR-30c and GALNT7 was analyzed by luciferase activity, RNA pull-down and RNA immunoprecipitation assays. And a xenograft mice model was established to verify the effect of miR-30c in regulating NK cell cytotoxicity to lung cancer cells in vivo. RESULTS: NK cell-derived exosomes carrying miR-30c, and miR-30c level was significantly downregulated in primary NK cells of lung cancer patients. MiR-30c overexpression promoted TNF-α and IFN-γ secretion and enhanced the cytotoxicity of interleukin 2 (IL-2)-treated NK cells to lung cancer cells, while knockdown of miR-30c played an opposite effect in regulating the cytotoxicity of NK cells to lung cancer cells. GALNT7 was a target of miR-30c and was negatively regulated by miR-30c. Besides, miR-30c targeted GALNT7 to exert its function in regulating NK cell cytotoxicity. Furthermore, GALNT7 prompted the activation of PI3K/AKT pathway in NK cells. Additionally, miR-30c overexpression enhanced NK cell cytotoxicity to lung cancer cells and inhibited tumor growth in vivo. CONCLUSION: miR-30c enhanced NK cell cytotoxicity to lung cancer cells via decreasing GALNT7 and inactivating the PI3K/AKT pathway, suggesting that regulating miR-30c expression maybe a promising approach for enhancing NK cell-based antitumor therapies.

Algorithm for systematic valve-crossing in transcatheter aortic valve implantation.

The retrograde valve-crossing of a stenotic aortic valve is a crucial step in the transcatheter aortic valve implantation procedure. In addition to being time-consuming and associated with an increased stroke risk, inappropriate valve-crossing may cause devastating complications. This tutorial review summarizes systematic and detailed techniques to cross the aortic valve. First, the main challenges in retrograde valve-crossing are depicted. Next, a step-by-step guidance on valve-crossing is provided, along with an in-depth description of the three-dimensional anatomy under a two-dimensional fluoroscopy view. Finally, modified techniques for different anatomies are described.

TRIM33 drives prostate tumor growth by stabilizing androgen receptor from Skp2-mediated degradation.

Androgen receptor (AR) is a master transcription factor that drives prostate cancer (PCa) development and progression. Alterations in the expression or activity of AR coregulators significantly impact the outcome of the disease. Using a proteomics approach, we identified the tripartite motif-containing 33 (TRIM33) as a novel transcriptional coactivator of AR. We demonstrate that TRIM33 facilitates AR chromatin binding to directly regulate a transcription program that promotes PCa progression. TRIM33 further stabilizes AR by protecting it from Skp2-mediated ubiquitination and proteasomal degradation. We also show that TRIM33 is essential for PCa tumor growth by avoiding cell-cycle arrest and apoptosis, and TRIM33 knockdown sensitizes PCa cells to AR antagonists. In clinical analyses, we find TRIM33 upregulated in multiple PCa patient cohorts. Finally, we uncover an AR-TRIM33-coactivated gene signature highly expressed in PCa tumors and predict disease recurrence. Overall, our results reveal that TRIM33 is an oncogenic AR coactivator in PCa and a potential therapeutic target for PCa treatment.

Transcaval transcatheter aortic valve implantation in bicuspid aortic valve: A step-by-step procedural guidance.

We report the case of a 78-year-old female with Sapien 3 transcatheter heart valve implantation in the transcaval approach. In this setting, we describe the step-by-step management and technique of the transcaval transcatheter aortic valve implantation.

Rotation characteristics and neo-commissural alignment of transcatheter heart valve in type-0 bicuspid aortic valve.

AIMS: This study sought to characterize the rotation of the transcatheter heart valve (THV) and evaluate the neo-commissures overlap with coronary arteries in type-0 bicuspid aortic valve (BAV). METHODS AND RESULTS: This was a single-center, 10-patient, retrospective observational cohort. Pre-TAVI computed tomography and procedural fluoroscopy were analyzed. Coplanar fluoroscopic views were coregistered to pre-TAVI computed tomography to characterize THV rotation and determine coronary overlap. The incidence of severe coronary artery overlap with one coronary artery was 90%. According to our prediction line, type-0 BAV has predicted a higher incidence of overlap with one coronary artery, but lower incidence with both coronary arteries compared to the tricuspid aortic valve (TAV). The rotational angles in two different phases were 3.8 ± 3.2° versus 11.8 ± 8.0° (p = .01) in patients with mixed cusp fusion. Commissural angles in final and initial deployment were 9.6 ± 6.6 versus 18.1 ± 11.0° (p = .021). Applying hypothetic "commissure-middle view" in 0°, ±5°, and ±10°, the incidence of overlap with one coronary artery are 20%, 40%, and 90% separately. CONCLUSIONS: The THV rotation existed and was activated in the last 1/3 deploying phase. With the observed tendency of "automatic commissural alignment," applying the "commissure-middle" view in type-0 BAV may optimize valve alignment and avoid coronary artery overlap.

Bioactive Poly(octanediol-citrate-polyglycol) Accelerates Skin Regeneration through M2 Polarization Immunomodulating and Early Angiogenesis.

The inhibition of inflammation and the promotion of early angiogenesis are paid much attention in skin tissue engineering. Citric acid-based biomaterials are widely used in tissue engineering due to their bioactive structure and biocompatibility, but there are few studies on investigating their role and mechanism in wound repair and skin regeneration. Herein, the potential anti-inflammation mechanism of poly(octanediol-citrate-polyglycol) (POCG) copolymer is reported in regulating skin wound repair. It is found that POCG can modulate macrophages phenotype through downregulating the expression of proinflammatory cytokines (tumor necrosis facor-α (Tnf-α), Interleukin-1ß (IL-1ß), and Interleukin-6 (IL-6) and polarizing macrophages to anti-inflammatory (M2) phenotype. POCG can promote endothelial cell vascularization by increasing the expression of angiogenesis factors (vascular endothelial growth factor (Vegf) and cluster of differentiation 31CD31) mediated by the macrophage polarization. The in vivo study shows that POCG can accelerate skin wound repair through suppressing the acute inflammation and inducing early angiogenesis through the polarization modulation. Furthermore, the POCG polymer has good biocompatibility for both immune cells and tissue cells. This study may provide the important theoretical support on the bioactivity of citrate-based biomaterials and expanding their applications in tissue engineering.
