RESUMEN
BACKGROUND: The triglyceride-glucose (TyG) index is associated with the development and prognosis of coronary artery disease (CAD). However, the impact of the TyG index on CAD severity across different glucose metabolism states exhibits significant disparities in previous research. METHODS: This cross-sectional study comprised 10,433 participants from a prospective cohort. Participants were categorized into four groups based on glucose metabolism state: normal glucose regulation (NGR), prediabetes (pre-DM), diabetes mellitus (DM) without insulin prescribed (Rx), and DM with insulin Rx. The TyG index was determined by the following formula: Ln [TG (mg/dL) × FPG (mg/dL) / 2], where TG is triglycerides and FPG is fasting plasm glucose. Statistical methods such as binary logistic regression, interaction analysis, restricted cubic spline (RCS), and receiver operating characteristic (ROC) were employed to analyze the relationship between the TyG index and CAD severity across the entire population and glucose metabolism subgroups. Mediation analysis was conducted to examine the mediating effects of glycated hemoglobin (HbA1c) on these relationships. Sensitivity analysis was performed to ensure the robustness of the findings. RESULTS: Multivariable logistic regression analysis revealed a significant positive association between the TyG index and multi-vessel CAD in the entire population (OR: 1.34; 95% CI: 1.22-1.47 per 1-unit increment). Subgroup analysis demonstrated consistent positive associations in the NGR, pre-DM, and DM non-insulin Rx groups, with the highest OR observed in the NGR group (OR: 1.67; 95% CI: 1.3-2.14 per 1-unit increment). No correlation was found in the DM with insulin Rx subgroup. RCS analyses indicated the distinct dose-response relationships across different glucose metabolism subgroups. Including the TyG index in the established model slightly improved the predictive accuracy, particularly in the NGR group. Mediation analyses showed varying mediating effects of HbA1c among different glucose metabolism subgroups. Sensitivity analysis confirmed the robustness of the aforementioned relationships in the new-onset CAD population and in individuals not using antilipidemic medications. CONCLUSIONS: The TyG index positively associated with CAD severity across all glucose metabolism states, except for individuals receiving insulin treatment. Moreover, it might serve as a supplementary noninvasive predictor of CAD severity in addition to established factors, especially in NGR patients.

Indium phosphide (InP) quantum dots (QDs) have become the most recognized prospect to be less-toxic surrogates for Cd-based optoelectronic systems. Due to the particularly dangling bonds (DBs) and the undesirable oxides, the photoluminescence performance and stability of InP QDs remain to be improved. Previous investigations largely focus on eliminating P-DBs and resultant surface oxidation states; however, little attention has been paid to the adverse effects of the surface In-DBs on InP QDs. This work demonstrates a facile one-step surface peeling and passivation treatment method for both In- and P-DBs for InP QDs. Meanwhile, the surface treatment may also effectively support the encapsulation of the ZnSe shell. Finally, the generated InP/ZnSe QDs display a narrower full width at half-maximum (fwhm) of â¼48 nm, higher photoluminescence quantum yields (PLQYs) of â¼70%, and superior stability. This work enlarges the surface chemistry engineering consideration of InP QDs and considerably promotes the development of efficient and stable optoelectronic devices.
RESUMEN
Global warming and heavy metal pollution pose tremendous challenges to human development, and photocatalysis is considered to be an effective strategy to solve these problems. Herein, copper(II) tetra (4-carboxyphenyl) porphyrin (CuTCPP) molecules were successfully in situ loaded onto Bi4O5Br2 by a hydrothermal approach. A series of experimental results show that the light absorption capacity and photogenerated carrier separation efficiency were synchronously enhanced after the construction of CuTCPP/Bi4O5Br2 composites. Hence, the as-prepared composites possess significantly improved photocatalytic ability for both CO2 and Cr(VI) reduction. Specifically, CuTCPP/Bi4O5Br2-2 achieves a CO generation rate of 17.14 µmol g-1 under 5 h irradiation, which is twice as high as that of Bi4O5Br2 (8.57 µmol g-1). Besides, the optimized CuTCPP/Bi4O5Br2-2 also exhibits a removal rate of 61.87% for Cr(VI) within 100 min under irradiation. Furthermore, the mechanism of CO2 and Cr(VI) photoreduction was explored by in situ Fourier transform infrared spectroscopy and capture experiments, respectively. This work can be a reference toward the construction of photocatalysts with high activity for solar energy conversion.
RESUMEN
White adipose tissue accumulation and inflammation contribute to obesity by inducing insulin resistance. Herein, we aimed to screen the synergistic components of the herbal pair Coptidis Rhizoma-Glycyrrhizae Radix et Rhizoma for the treatment of insulin resistance and explore the potential synergistic mechanisms. Enzyme-linked immunosorbent assay and quantitative PCR were used to detect expression levels of inflammatory genes in vitro and in vivo. Western blotting and immunohistochemistry were performed to detect protein levels of the insulin signaling pathway and macrophage markers. The effects on obesity-induced insulin resistance were verified using a diet-induced obesity (DIO) mouse model. Interactions between macrophage and adipocyte were assessed using a cellular supernatant transfer assay. Berberine (BBR) and isoliquiritigenin (ISL) alleviated mRNA levels and secretion of inflammatory genes in vitro and in vivo. Furthermore, BBR acted synergistically with ISL to ameliorate obesity and dyslipidemia in DIO mice. Meanwhile, the combination treatment significantly improved glucose intolerance and insulin resistance and decreased M1-macrophage accumulation and infiltration in the adipose tissue. Mechanistically, co-treatment with BBR and ISL upregulated the protein expression of the IRS1-PI3K-Akt insulin signaling pathway, enhanced glucose uptake in adipocyte, and suppressed the interaction between macrophage and adipocyte. BBR and ISL were identified as the synergistic components of the herbal pair Coptidis Rhizoma-Glycyrrhizae Radix et Rhizoma for treating insulin resistance. The synergistic combination of BBR with ISL can be a promising and effective strategy for improving obesity-induced adipose inflammation and insulin resistance.

Malicious social bots pose a serious threat to social network security by spreading false information and guiding bad opinions in social networks. The singularity and scarcity of single organization data and the high cost of labeling social bots have given rise to the construction of federated models that combine federated learning with social bot detection. In this paper, we first combine the federated learning framework with the Relational Graph Convolutional Neural Network (RGCN) model to achieve federated social bot detection. A class-level cross entropy loss function is applied in the local model training to mitigate the effects of the class imbalance problem in local data. To address the data heterogeneity issue from multiple participants, we optimize the classical federated learning algorithm by applying knowledge distillation methods. Specifically, we adjust the client-side and server-side models separately: training a global generator to generate pseudo-samples based on the local data distribution knowledge to correct the optimization direction of client-side classification models, and integrating client-side classification models' knowledge on the server side to guide the training of the global classification model. We conduct extensive experiments on widely used datasets, and the results demonstrate the effectiveness of our approach in social bot detection in heterogeneous data scenarios. Compared to baseline methods, our approach achieves a nearly 3-10% improvement in detection accuracy when the data heterogeneity is larger. Additionally, our method achieves the specified accuracy with minimal communication rounds.
RESUMEN
The involvement of necroptosis in the immunosuppressive tumor microenvironment has been established and has been shown to contribute to the growth of pancreatic ductal adenocarcinoma, indicating its role in promoting tumor development. However, the relationship between necroptosis and bladder urothelial carcinoma (BUC) has yet to be fully understood. To shed light on this issue, our study aimed to uncover the impact of necroptosis on immune cell infiltration and immunotherapy response in BUC patients. We conducted an analysis of 67 necroptosis genes to assess their expression and genomic changes across pan-cancer and identified 12 necroptosis genes that are prognostically relevant and associated with immune subtypes and tumor stemness in BUC. Using a public database of 1841 BUC samples, we then performed Unsupervised Cluster Analysis and discovered two distinct necroptotic phenotypes in BUC. These phenotypes showed significant differences in molecular subtypes, immune infiltration patterns, and gene mutation profiles. We confirmed this discovery in BUC through qPCR and WB experiments. To evaluate the impact of necroptosis on prognosis, chemotherapy sensitivity, and immunotherapy response (such as anti-PD-L1), we developed a principal component analysis model called NecroScore. Finally, we validated the effects of RIPK3 and MLKL through a nude mouse transplantation model for BUC. Our study has uncovered that necroptosis plays a role in shaping the tumor immune microenvironment in BUC. The high necroptosis phenotype (Cluster B) was characterized by a higher abundance of tumor immunosuppressive cells and more key biological processes driving tumor progression, while the low necroptosis group (Cluster A) had higher FGFR3 mutations. We found that the infiltration levels of immune cells, including CD8+ T cells, were significantly different between FGFR3 mutated and wild-type (WT) samples. Our results confirmed the reliability of NecroScore as a comprehensive assessment tool for evaluating the immunotherapeutic effect and prognosis of BUC patients, with high NecroScore values favoring basal-like differentiation and lower FGFR3 alterations. We also observed that high expression of MLKL had a significant inhibitory effect on tumor growth and increased neutrophil infiltration in vivo. In our study, we uncovered the regulation pattern of necroptosis in the tumor immune microenvironment of BUC. Additionally, we developed a scoring tool called NecroScore that can be utilized to predict the most suitable chemotherapy and immunotherapy strategy for bladder urothelial carcinoma patients. This tool can effectively guide the chemotherapy and immunotherapy regimens for patients with advanced BUC.

Hepatic sinusoidal obstruction syndrome (HSOS) is a death-dealing liver disease with a fatality rate of up to 67%. In the study present, we explored the efficacy of andrographolide (Andro), a diterpene lactone from Andrographis Herba, in ameliorating the monocrotaline (MCT)-induced HSOS and the underlying mechanism. The alleviation of Andro on MCT-induced rats HSOS was proved by biochemical index detection, electron microscope observation, and liver histological evaluation. Detection of hepatic ATP content, mitochondrial DNA (mtDNA) copy number, and protein expression of nuclear respiratory factor-1 (NRF1) and peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PPARGC1A) demonstrated that Andro strengthened mitochondrial biogenesis in livers from MCT-treated rats. Chromatin immunoprecipitation assay exhibited that Andro enhanced the occupation of nuclear factor erythroid 2-related factor 2 (NFE2L2, also known as NRF2) in the promoter regions of both PPARGC1A and NRF1. Andro also activated the NRF2-dependent anti-oxidative response and alleviated liver oxidative injury. In Nrf2 knock-out mice, MCT induced more severe liver damage, and Andro showed no alleviation in it. Furthermore, the Andro-activated mitochondrial biogenesis and anti-oxidative response were reduced in Nrf2 knock-out mice. Contrastingly, knocking out Kelch-like ECH-associated protein 1 (Keap1), a NRF2 repressor, reduced MCT-induced liver damage. Results from co-immunoprecipitation, molecular docking analysis, biotin-Andro pull-down, cellular thermal shift assay, and surface plasmon resonance assay showed that Andro hindered the NRF2-KEAP1 interaction via directly binding to KEAP1. In conclusion, our results revealed that NRF2-dependent liver mitochondrial biogenesis and anti-oxidative response were essential for the Andro-provided alleviation of the MCT-induced HSOS. Graphical Headlights: 1. Andro alleviated MCT-induced HSOS via activating antioxidative response and promoting mitochondrial biogenesis. 2. Andro-activated antioxidative response and mitochondrial biogenesis were NRF2-dependent. 3. Andro activated NRF2 via binding to KEAP1.

Machine learning (ML) models have received increasing attention as a new approach for the virtual screening of organic materials. Although some ML models trained on large databases have achieved high prediction accuracy, the application of ML to certain types of organic materials is limited by the small amount of available data. On the other hand, metalloporphyrins and porphyrins (MpPs) have received increasing attention as potential photocatalysts, and recent studies have found that both HOMO/LUMO energy levels and energy gaps are important factors controlling the MpP photocatalysts. Since the training data of MpPs are insufficient and limited to porphyrin-based dyes, in this study, we proposed a deep transfer learning approach to rapidly predict the HOMO/LUMO energy levels and energy gaps of MpPs. To complement the open-source Porphyrin-based Dyes Database (PBDD), we curated a new database, the Metalloporphyrins and Porphyrins Database (MpPD), in which MpPs were specifically designed as potential photocatalysts and the HOMO/LUMO energies were calculated by advanced DFT functionals. We proposed PorphyBERT, a BERT-based regression model that was pre-trained with PBDD and fine-tuned with MpPD. The model performed satisfactorily in predicting HOMO and LUMO energies and energy gap with RMSEs of 0.0955, 0.0988, and 0.0787 eV and MAEs of 0.0774, 0.0824, and 0.0549 eV. Furthermore, due to its unique unsupervised pre-training phase, the model is not affected by the difference in computational functionals between pre-training and fine-tuning databases. Finally, we recommended 12 MpPs as potential photocatalysts for CO2 reduction with out-of-sample model predictions of energy gaps close to the values calculated by DFT.
RESUMEN
INTRODUCTION AND HYPOTHESIS: The study was aimed at exploring the 50 most cited articles related to vaginal tightening. METHODS: The papers were searched through the Thomson Reuters Web of Science on 30 July 2022, and were ranked by the total number of citations. The included articles were analyzed for author, journal, country, number of citations, keywords, subject matter, and level of evidence. The search output was also imported into VOSviewer. RESULTS: The 50 most cited articles were cited a combined total of 2,558 times. The papers were published between 1990 and 2020, of which 86% were published between 2010 and 2020. They included 38 original articles, 8 reviews, 3 editorial articles, and 1 letter. Most articles were published in gynecology-related journals (n=30, 60%). The articles covered a wide range of topics, the most common being laser/radiofrequency treatment, vaginal tightening procedures, and urinary incontinence. The majority presented findings supported by level IV or V evidence. Through co-occurrence analysis, high-frequency words and countries were displayed well. CONCLUSIONS: The study shed light on frequently read articles and influential topics about vaginal tightening. The highly cited literature mainly focused on laser or radiofrequency treatments and gynecologists currently dominate the highly cited literature on vaginal tightening. The articles related to surgical treatments are low in number and evidence level so far. The co-occurrence analysis reveals the hot research content and active countries in the field. In general, the study provides useful evidence for future research and educational materials.

BACKGROUND AND OBJECTIVES: Albuminuria is recognized as being a predictor of cardiovascular and renal disease. We aimed to identify the impact of the long-term burden and trends of systolic blood pressure on albuminuria in midlife, as well as to explore sex differences concerning this relationship. METHODS: This longitudinal study consisted of 1,683 adults who had been examined 4 or more times for blood pressure starting in childhood, with a follow-up time period of 30 years. The cumulative effect and longitudinal trend of blood pressure were identified by using the area under the curve (AUC) of individual systolic blood pressure measurement with a growth curve random effects model. RESULTS: Over 30 years of follow-up, 190 people developed albuminuria, including 53.2% males and 46.8% females (aged 43.39 ± 3.13 years in the latest follow-up). The urine albumin-to-creatinine ratio (uACR) values increased as the total and incremental AUC values increased. Additionally, women had a higher albuminuria incidence in the higher SBP AUC groups than men do (13.3% for men vs. 33.7% for women). Logistic regression showed that the ORs of albuminuria for males and females in the high total AUC group were 1.34 (0.70-2.60) and 2.94 (1.50-5.74), respectively. Similar associations were found in the incremental AUC groups. CONCLUSIONS: Higher cumulative SBP was correlated with higher uACR levels and a risk of albuminuria in middle age, especially in women. The identification and control of cumulative SBP levels from an early age may assist in reducing the incidences of renal and cardiovascular disease for individuals in later life.

OBJECTIVE: To investigate the effect of sub-regional split-thickness skin grafting in perineal resurfacing. METHODS: A single-center retrospective study was conducted in the Genital Plastic Surgery Center. Detailed clinical data of 14 consecutive patients who underwent split-thickness skin grafting after vulvar tumor resection from February 2013 to June 2022 were analyzed. Clinical data, postoperative photographs, scoring of vulvar appearance, and questionnaire results of the Female Sexual Function Index before and after surgery were analyzed. RESULTS: The patients had sub-regional split-thickness skin grafting ranging from 7 × 8 cm to 11 × 12 cm (88.86 ± 24.99 cm2 ). After a follow-up of 8.21 ± 2.22 months (mean ± SD), all patients had a three-dimensional and aesthetically pleasing vulva and high scoring of vulvar appearance (mean ± SD, 4.43 ± 0.65). All patients had good healing of both the recipient and donor sites without major complications. Only one patient had minor dehiscence in the perineal region and recovered soon after proper treatment. The scores of the Female Sexual Function Index were significantly improved after surgery. Among the included domains, scores of "desire," "arousal," "orgasm" and "satisfaction" increased significantly after surgery (p value <0.05). CONCLUSIONS: Sub-regional split-thickness skin grafting could achieve excellent cosmetic outcomes with few complications in perineal reconstruction after the excision of superficial vulvar tumors. It can provide an aesthetically pleasing appearance in the vulvar region and improve female sexual function to some extent. In general, sub-regional split-thickness skin grafting could be a recommended reconstructive option to repair vulvar defects.

BACKGROUND: Plastic surgery has grown rapidly over the past decade, with increasing scientific output. The emergence of coronavirus disease 2019 (COVID-19) has a considerable impact on plastic surgery. OBJECTIVE: To identify trends in published literature in plastic surgery from 2011 to 2021. To explore the impact of COVID-19 on scientific research output through bibliometric analysis methods. METHODS: Web of Science was searched by authors on December 23, 2021. Published papers about plastic surgery over the last decade were analyzed. The search output was imported into VOSviewer for science mapping. RESULTS: The actual number of papers related to plastic surgery during the COVID-19 period was higher than expected one. For scientific outputs in plastic surgery, keywords about surgical practice had a high frequency. "Reconstruction," "effect," "flap," "tissue," "defect," "model" maintained a high level of heat before and after COVID-19. The heat of "risk," "complication," "review," "infection," "cohort," and "meta-analysis" increased after the outbreak of COVID-19. The international collaboration showed an upward trend despite the impact of COVID-19. From the perspective of the volume of plastic surgery publications, some journals had a more positive performance compared to the pre-epidemic period. The proportion of original articles decreased after the spread of COVID-19 from 70.26% to 63.84%. CONCLUSION: Although the COVID-19 has a profound impact on the healthcare industry, the bibliographic data reveals an increasing scientific output in the field of plastic surgery over time. For plastic surgery, high-frequency terms, research hotspots, popular journals, article types, and international collaboration have changed under the influence of COVID-19.

BACKGROUND: VQ motif-containing (VQ) proteins are cofactors of transcriptional regulation that are widely involved in plant growth and development and respond to various stresses. The VQ gene family has been identified and characterized for many plants, but there is little research on VQ gene family proteins in wheat (Triticum aestivum L.). RESULTS: In this study, 113 TaVQ genes (40 homoeologous groups) were identified in the wheat genome. TaVQ proteins all contain the conserved motif FxxhVQxhTG, and most of the TaVQ genes do not contain introns. Phylogenetic analysis demonstrated that TaVQ proteins can be divided into 8 subgroups (I-VIII). The chromosomal location mapping analysis indicated that TaVQ genes are disproportionally distributed on 21 wheat chromosomes. Gene duplication analysis revealed that segmental duplication significantly contributes to the expansion of the TaVQ gene family. Gene expression analysis demonstrated that the expression pattern of TaVQ genes varies in different tissues. The results of quantitative real-time PCR (qRT-PCR) found that TaVQ genes displayed different expression levels under different phytohormones and abiotic stresses. The cis-elements analysis of the promoter region demonstrated that stress responses, hormone responses, growth and development, and WRKY binding elements are all widely distributed. Additionally, a potential regulatory network between TaVQ proteins and WRKY transcription factors was visualized. CONCLUSION: This study systematically analyzed the wheat TaVQ gene family, providing a reference for further functional characterization of TaVQ genes in wheat.

Intact and healthy hair follicles are important for hair growth after hair follicle transplantation. However, effective and practical evaluation methods for the quality of hair follicles are currently lacking. In the present study, we developed a novel fast staining method for histological examination of hair follicles. The whisker follicles from mice were used to explore the staining protocols, and the final protocol for the evaluation of human hair follicles was derived from animal experiments. After extraction, human hair follicles or mouse whisker follicles were permeabilized with 0.3% Triton X-100. Subsequently, hair follicles were processed by either hematoxylin or alkaline phosphatase staining. The integrity and growth state, including the status of hair follicle stem cells and blood vessels of the extracted hair follicles, were clearly identified under a light microscope. Unhealthy hair follicles from donors or hair follicles broken during extraction were easily revealed by this method. Importantly, it took less than half an hour to obtain images of an individual hair follicle. This method is simple and practical for evaluating the quality and status of hair follicles, providing a fast-screening procedure for hair follicle transplantation.

BACKGROUND: The triglyceride-glucose index (TyG index) has emerged as a reliable surrogate marker of insulin resistance associated with arterial stiffness. However, most studies were based on a cross-sectional design, and few studies have evaluated the longitudinal impact of the TyG index on arterial stiffness. This study aimed to investigate the associations of single time point measurement and the long-term trajectory of the TyG index with arterial stiffness in a Chinese cohort. METHODS: Data are derived from the Hanzhong Adolescent Hypertension Cohort study. A total of 2480 individuals who participated in the 2017 survey was included in the cross-sectional analysis. A sample of 180 individuals from the sub-cohort with follow-up data in 2005, 2013, and 2017 was enrolled in the longitudinal analysis. The TyG index was calculated as ln (fasting triglyceride [mg/dL] × fasting glucose [mg/dL]/2), and arterial stiffness was determined using brachial-ankle pulse wave velocity (baPWV). The latent class growth mixture modeling method was used to identify the TyG index trajectories from 2005 to 2017. RESULTS: In the cross-sectional analysis, the median age of the study population was 42.8 (39.8, 44.9) years, and 1351 (54.5%) were males. Each one-unit increment in TyG index was associated with a 37.1 cm/s increase (95% confidence interval [CI] 23.7-50.6 cm/s; P < 0.001) in baPWV, and similar results were observed when the TyG index was in the form of quartiles. In the longitudinal analysis, we identified three distinct TyG index trajectories and found that the highest TyG index trajectory carried the greatest odds of increased arterial stiffness, with a fully adjusted odds ratio (OR) of 2.76 (95% CI 1.40, 7.54). CONCLUSIONS: Elevated levels of baseline TyG index and higher long-term trajectory of TyG index were independently associated with increased arterial stiffness. Monitoring immediate levels and longitudinal trends of the TyG index may help with the prevention of arterial stiffness in the long run.

BACKGROUND: The advantages of prophylactic central lymph node dissection (CLND) for clinically node-negative patients remained a great deal of controversies. Our research was aimed to analyze the relationship between cervical central lymph node metastasis (CLNM) and BRAFV600E mutation, ultrasonic and clinicopathologic characterizes in papillary thyroid carcinoma (PTC). METHODS AND MATERIALS: In current study, a total of 112 consecutive PTC patients who experienced thyroidectomy plus cervical central neck dissection were included in our research. All PTC were pre-operatively analyzed by ultrasonic features, including tumor size, multifocality or not, tumor location, internal components, echogenicity, microcalcification, margins, orientation, taller than wide shape, and internal vascularity. The presence of clinicopathologic factors, including age, sex, T stage, Hashimoto's thyroiditis, and BRAFV600E mutation was then investigated. Univariate and multivariate analysis were conducted to check into the relationship between predictive factors and cervical CLNM in PTC patients, and then a predictive model was also established. RESULTS: Pathologically, 58.0% (65/112) of the PTC patients harbored cervical CLNM. Univariate and multivariate analysis were conducted to identify age < 55 years, tumor size > 10 mm, microcalcification, non-concomitant Hashimoto's thyroiditis and BRAFV600E mutation were predictive factors for cervical CLNM in PTC. The risk score for cervical CLNM in PTC patients was calculated: risk score = 1.284 × (if age < 55 years) + 1.241 × (if tumor size > 10 mm) + 1.143 × (if microcalcification) - 2.097 × (if concomitant Hashimoto's thyroiditis) + 1.628 × (if BRAFV600E mutation). CONCLUSION: Age < 55 years old, PTC > 10 mm, microcalcification, non-concomitant Hashimoto's thyroiditis and BRAFV600E mutation are predictive factors for cervical CLNM. BRAFV600E mutation by pre-operative US-FNA technology synergized with clinicopathologic and ultrasonic features is expected to guide the appropriate surgical management for PTC patients.

The objective of the study was to investigate the expression levels of potassium voltage-gated channel subfamily A member 5 (KCNA5), connexin 43 (Cx43), and connexin 40 (Cx40) in the left atrial appendage of patients with atrial fibrillation (AF) and the interactions between them. We gathered tissue samples from patients with persistent AF and sinus rhythm and used fluorescence quantitative polymerase chain reaction to evaluate messenger RNA (mRNA) changes of KCNA5, Cx43, and Cx40. Then, we studied the protein levels of KCNA5, Cx43, and Cx40 by immunofluorescence and western blot analysis and the interactions between these proteins were identified by immunoprecipitation and immunofluorescence colocation, respectively. Compared with the control group, the mRNA and protein levels of KCNA5, Cx43, and Cx40 in the AF group were decreased and the positive expression of KCNA5, Cx43, and Cx40 protein was also decreased by immunofluorescence staining in the AF group. In addition, immunoprecipitation and immunofluorescence colocation revealed that KCNA5 was coexpressed with Cx43 and Cx40 proteins. The expressions of KCNA5, Cx43, and Cx40 were substantially downregulated in the myocardium of patients with AF and KCNA5 interacted with Cx43 and Cx40 proteins, respectively.

BACKGROUND: Glycolysis reprogramming is deeply involved in the progression of hepatocellular carcinoma (HCC), in which HCC cells with stemness traits play important roles as well. Thus, whether platelet isoform of phosphofructokinase 1 (PFKP), a rate-limiting enzyme in glycolysis, contributes to the maintenance of stemness of HCC cells is worth investigation. METHODS: PFKP levels were compared between human hepatocellular carcinoma and adjacent normal tissues by Western blotting and immunohistochemistry. The relationship between PFKP expression and clinic pathological features was also analyzed. Furthermore, the colony formation capabilities and the levels of stemness markers (ALDH1, CD44, CD133, Sox-2) as well as ß-catenin were compared between HCC cells either undergoing PFKP silencing or overexpression. RESULTS: PFKP levels were higher in HCC as compared to normal hepatic tissues. Silencing PFKP decreased HCC proliferation, colony formation capabilities, and levels of stemness markers and ß-catenin; whereas overexpressing PFKP demonstrated the opposite effects. CONCLUSION: PFKP promoted HCC proliferation and contributed to the maintenance of HCC stemness. Silencing PFKP could restrain the stemness of HCC, suggesting that PFKP may be a potential therapeutic target for HCC treatment.

OBJECTIVE: To evaluate the comprehensive complication index(CCI) and Clavien-Dindo classification(CDC) for short-term postoperative complications in radical cystectomy and assess cumulative surgical morbidity to compare sufficient surgical skill. METHODS: From September 30, 2010, to October 1, 2020, clinical data of patients with urothelial carcinoma who underwent radical cystectomy with urinary diversion were gathered, patients who had only a urinary diversion, bladder sparing surgery, additional abdominal surgeries at the same time were all excluded. The CDC and CCI were utilized to evaluate 30-d complications after radical cystectomy and the relevance of hospital stay was compared between CCI and CDC. The cumulative sum control models (CUSUM) were used to evaluate the overall surgical morbidity of radical cystectomy in our facility and for comparisons between surgeons. RESULTS: This study enrolled a total of 635 individuals, 548 (86.3%) of whom had 1124 problems. The incidence of severe complications (CDC≥ Grade III) was 10.2%. The average CCI was 20.2 ± 14.7. Gender, urinary diversion subtype, procedure method, and surgeon were significantly correlated with the increase of CCI (p < 0.05). The CCI demonstrated a better relationship with hospital stay (R2 = 0.429) than the CDC (R2 = 0.361). The CUSUM-CCI model demonstrated a difference and growth distribution in dynamic time between individual surgeons. CONCLUSIONS: CCI can better reflect the incidence of complications for radical cystectomy than CDC, and CCI is more strongly correlated with postoperative hospital stay. The CUSUM-CCI model can reflect the quality of surgical skill for each surgeon instantaneously.

BACKGROUND: It is difficult to plan a simple and effective surgical strategy for patients with horizontal and vertical redundant tissue of the labia minora and clitoral hood redundancy. A single edge resection or wedge resection labiaplasty with clitoral hood reduction that simultaneously resolves these three issues has yet to be reported. This study investigated the clinical effects and safety of trilobal labiaplasty via a composite incision. METHODS: The single-center, retrospective, observational study included data from patients with hypertrophy of the labia minora and clitoral hood who underwent trilobal labiaplasty. RESULTS: Altogether, 136 patients (average age: 31.6 ± 8.82 years; range: 21-53 years; 224 sides) sought surgery for aesthetic (39/136, 28.7%), functional (17/136, 12.5%), or both reasons (80/136, 58.8%). Overall, 134 patients (134/136, 98.5%) were followed up for 3 months. No serious complications or malformations occurred. Three patients (2.2%) underwent secondary repair surgery due to incomplete bilateral symmetry, 122 (91.0%) scored ≥ 21 points on the Female Genital Self-Image Scale, 107 (91.5%) were satisfied with the cosmetic outcomes, and 93 (95.9%) were satisfied with the functional improvement. CONCLUSIONS: Trilobal labiaplasty performed via a composite incision using edge and wedge labiaplasty to adjust horizontal and vertical hypertrophy of the labia minora and remove lateral folds of the clitoris is a safe and effective method to improve the appearance and rearrange the position of the clitoral hood and clitoral frenulum while preserving the fine structure of the surrounding tissue. This method results in few complications and high functional and aesthetic satisfaction rates. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.
