Combined Use of Emapalumab With Ruxolitinib and Dexamethasone as an Effective Treatment for Epstein-Barr Virus-associated Hemophagocytic Lymphohistiocytosis Complicated With Multiorgan Damage and Severe Infection.

Anti-interferon-γ monoclonal antibody emapalumab and JAK1/2 inhibitors ruxolitinib have been widely reported for the treatment of hemophagocytic lymphohistiocytosis (HLH) recently. These targeted drugs have fewer side effects and may provide new options for patients with HLH who are refractory to previous treatment or intolerant to chemotherapy. Herein, we reported a case of Epstein-Barr virus-related HLH, which did not respond well to HLH-94 plus ruxolitinib and developed severe fungal infection. The disease was successfully controlled after a combination therapy of emapalumab, ruxolitinib, and dexamethasone.

Genome-Wide Identification and Characterization of the CCT Gene Family in Rapeseed (Brassica napus L.).

The CCT gene family is present in plants and is involved in biological processes such as flowering, circadian rhythm regulation, plant growth and development, and stress resistance. We identified 87, 62, 46, and 40 CCTs at the whole-genome level in B. napus, B. rapa, B. oleracea, and A. thaliana, respectively. The CCTs can be classified into five groups based on evolutionary relationships, and each of these groups can be further subdivided into three subfamilies (COL, CMF, and PRR) based on function. Our analysis of chromosome localization, gene structure, collinearity, cis-acting elements, and expression patterns in B. napus revealed that the distribution of the 87 BnaCCTs on the chromosomes of B. napus was uneven. Analysis of gene structure and conserved motifs revealed that, with the exception of a few genes that may have lost structural domains, the majority of genes within the same group exhibited similar structures and conserved domains. The gene collinearity analysis identified 72 orthologous genes, indicating gene duplication and expansion during the evolution of BnaCCTs. Analysis of cis-acting elements identified several elements related to abiotic and biotic stress, plant hormone response, and plant growth and development in the promoter regions of BnaCCTs. Expression pattern and protein interaction network analysis showed that BnaCCTs are differentially expressed in various tissues and under stress conditions. The PRR subfamily genes have the highest number of interacting proteins, indicating their significant role in the growth, development, and response to abiotic stress of B. napus.

Role of mitochondrial dysfunction in kidney disease: Insights from the cGAS-STING signaling pathway.

ABSTRACT: Over the past decade, mitochondrial dysfunction has been investigated as a key contributor to acute and chronic kidney disease. However, the precise molecular mechanisms linking mitochondrial damage to kidney disease remain elusive. The recent insights into the cyclic guanosine monophosphate-adenosine monophosphate (GMP-AMP) synthetase (cGAS)-stimulator of interferon gene (STING) signaling pathway have revealed its involvement in many renal diseases. One of these findings is that mitochondrial DNA (mtDNA) induces inflammatory responses via the cGAS-STING pathway. Herein, we provide an overview of the mechanisms underlying mtDNA release following mitochondrial damage, focusing specifically on the association between mtDNA release-activated cGAS-STING signaling and the development of kidney diseases. Furthermore, we summarize the latest findings of cGAS-STING signaling pathway in cell, with a particular emphasis on its downstream signaling related to kidney diseases. This review intends to enhance our understanding of the intricate relationship among the cGAS-STING pathway, kidney diseases, and mitochondrial dysfunction.

Critical role of FGF21 in diabetic kidney disease: from energy metabolism to innate immunity.

Diabetic kidney disease (DKD) stands as the predominant cause of chronic kidney disease (CKD) on a global scale, with its incidence witnessing a consistent annual rise, thereby imposing a substantial burden on public health. The pathogenesis of DKD is primarily rooted in metabolic disorders and inflammation. Recent years have seen a surge in studies highlighting the regulatory impact of energy metabolism on innate immunity, forging a significant area of research interest. Within this context, fibroblast growth factor 21 (FGF21), recognized as an energy metabolism regulator, assumes a pivotal role. Beyond its role in maintaining glucose and lipid metabolism homeostasis, FGF21 exerts regulatory influence on innate immunity, concurrently inhibiting inflammation and fibrosis. Serving as a nexus between energy metabolism and innate immunity, FGF21 has evolved into a therapeutic target for diabetes, nonalcoholic steatohepatitis, and cardiovascular diseases. While the relationship between FGF21 and DKD has garnered increased attention in recent studies, a comprehensive exploration of this association has yet to be systematically addressed. This paper seeks to fill this gap by summarizing the mechanisms through which FGF21 operates in DKD, encompassing facets of energy metabolism and innate immunity. Additionally, we aim to assess the diagnostic and prognostic value of FGF21 in DKD and explore its potential role as a treatment modality for the condition.

The value of CT-based radiomics in predicting hemorrhagic transformation in acute ischemic stroke patients without recanalization therapy.

Objective: The aim of this study is to investigate the clinical value of radiomics based on non-enhanced head CT in the prediction of hemorrhage transformation in acute ischemic stroke (AIS). Materials and methods: A total of 140 patients diagnosed with AIS from January 2015 to August 2022 were enrolled. Radiomic features from infarcted areas on non-enhanced CT images were extracted using ITK-SNAP. The max-relevance and min-redundancy (mRMR) and the least absolute shrinkage and selection operator (LASSO) were used to select features. The radiomics signature was then constructed by multiple logistic regressions. The clinicoradiomics nomogram was constructed by combining radiomics signature and clinical characteristics. All predictive models were constructed in the training group, and these were verified in the validation group. All models were evaluated with the receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA). Results: Of the 140 patients, 59 experienced hemorrhagic transformation, while 81 remained stable. The radiomics signature was constructed by 10 radiomics features. The clinicoradiomics nomogram was constructed by combining radiomics signature and atrial fibrillation. The area under the ROC curve (AUCs) of the clinical model, radiomics signature, and clinicoradiomics nomogram for predicting hemorrhagic transformation in the training group were 0.64, 0.86, and 0.86, respectively. The AUCs of the clinical model, radiomics signature, and clinicoradiomics nomogram for predicting hemorrhagic transformation in the validation group were 0.63, 0.90, and 0.90, respectively. The DCA curves showed that the radiomics signature performed well as well as the clinicoradiomics nomogram. The DCA curve showed that the clinical application value of the radiomics signature is similar to that of the clinicoradiomics nomogram. Conclusion: The radiomics signature, constructed without incorporating clinical characteristics, can independently and effectively predict hemorrhagic transformation in AIS patients.

Inducing preferential growth of the Zn (002) plane by using a multifunctional chelator for achieving highly reversible Zn anodes.

Aqueous zinc-ion batteries (AZIBs) have demonstrated great potential for large-scale energy storage. However, their practical applications have been restricted by fast Zn dendrite growth and severe side reactions at the Zn/electrolyte interface. Herein, sodium gluconate is incorporated into a mild acidic electrolyte as a multifunctional additive to stabilize the Zn anode. Experiments and theoretical calculations reveal that the SG additive can induce planar growth of Zn along its (002) direction, thereby inhibiting Zn dendrite growth. This dendrite inhibition effect is attributed to the preferential adsorption of Zn2+ on the Zn (002) plane, while the Zn (100) and (101) planes are shielded by gluconate ions. Consequently, Zn||Zn symmetric cells with the electrolyte additive exhibit significantly prolonged cycle lives of 2000 h at 1 mA cm-2, 1 mA h cm-2 and 900 h at 5 mA cm-2, 2.5 mA h cm-2. Futhermore, the Zn||NH4V4O10 full cell retains 95% of its initial capacity after 2000 cycles at a current density of 5 A g-1 with an average CE of nearly 100%. This work offers a cost-effective strategy to enhance the electrochemical performance of AZIBs.

Co-Occurring Thrombotic Thrombocytopenic Purpura and Autoimmune Hemolytic Anemia in a Child Carrying the Pathogenic SHOC2 c.4A>G (p.Ser2Gly) Variant.

BACKGROUND RASopathies involve mutations in genes that encode proteins participating in the RAS-mitogen-activated protein kinase pathway and are a collection of multisystem disorders that clinically overlap. Variants in the SHOC2 gene have been reported in Noonan-like syndrome, which include distinct facial features, short stature, congenital cardiac defects, developmental delays, bleeding disorders, and loose anagen hair. This report is of a 7-year-old girl with the c.4A>G (p.Ser2Gly) variant of the SHOC2 gene, consistent with Noonan-like syndrome, with loose anagen hair, presenting with thrombotic thrombocytopenic purpura and autoimmune hemolytic anemia. CASE REPORT The child had a medical history of 7 hospitalizations at our institution. At the age of 2 months, she underwent surgical correction for ventricular and atrial septal defects. At the age of 2 years, tonsil and adenoid removal surgery was performed, followed by surgery for otitis media at age 5 years. At 7 years, she was hospitalized for the simultaneous occurrence of thrombotic thrombocytopenic purpura and autoimmune hemolytic anemia. The patient displayed short stature and mild intellectual disability. Notable facial features included sparse hair, mild frontal bossing, and low-set ears. Antinuclear antibody levels demonstrated a significant gradual shift. Through trio whole-exome sequencing, a c.4A>G (p.Ser2Gly) variation in the SHOC2 gene was identified. CONCLUSIONS Given the clinical information and genetic testing results, the patient's condition appeared to closely be a type of RASopathy. This report has highlighted the importance of physical, developmental, and genetic testing in children presenting with dysmorphism, developmental delay, and hematological abnormalities.

Successful management of tracheal lobular capillary hemangioma with arterial embolization followed by electrosurgical snaring via flexible bronchoscopy in an 11-year-old boy: A case report and literature review.

Lobular capillary hemangioma (LCH), previously known as pyogenic granuloma, is a benign vascular lesion commonly found within the oral and nasal cavities. However, it is rarely encountered within the trachea, especially in pediatric patients, where it manifests as hemoptysis, cough, and wheeze, and is frequently misdiagnosed as bronchitis or asthma. There is limited literature on the presentation, behavior, and management of tracheal LCH. Herein, we describe a rare case of tracheal LCH in an 11-year-old boy with a history of hemoptysis, which was successfully managed with arterial embolization followed by electrocautery loop snaring via flexible bronchoscopy. No complications occurred during and after the procedure. A review of the relevant literature is also provided. Our case is unique, given the therapeutic strategy utilized for pediatric tracheal LCH, and reminds physicians to be aware of tracheal LCH in the differential diagnosis for hemoptysis.

Stroke risk study based on deep learning-based magnetic resonance imaging carotid plaque automatic segmentation algorithm.

Introduction: The primary factor for cardiovascular disease and upcoming cardiovascular events is atherosclerosis. Recently, carotid plaque texture, as observed on ultrasonography, is varied and difficult to classify with the human eye due to substantial inter-observer variability. High-resolution magnetic resonance (MR) plaque imaging offers naturally superior soft tissue contrasts to computed tomography (CT) and ultrasonography, and combining different contrast weightings may provide more useful information. Radiation freeness and operator independence are two additional benefits of M RI. However, other than preliminary research on MR texture analysis of basilar artery plaque, there is currently no information addressing MR radiomics on the carotid plaque. Methods: For the automatic segmentation of MRI scans to detect carotid plaque for stroke risk assessment, there is a need for a computer-aided autonomous framework to classify MRI scans automatically. We used to detect carotid plaque from MRI scans for stroke risk assessment pre-trained models, fine-tuned them, and adjusted hyperparameters according to our problem. Results: Our trained YOLO V3 model achieved 94.81% accuracy, RCNN achieved 92.53% accuracy, and MobileNet achieved 90.23% in identifying carotid plaque from MRI scans for stroke risk assessment. Our approach will prevent incorrect diagnoses brought on by poor image quality and personal experience. Conclusion: The evaluations in this work have demonstrated that this methodology produces acceptable results for classifying magnetic resonance imaging (MRI) data.

Disseminated Cunninghamella elegans Infection Diagnosed by mNGS During Induction Therapy in a Child With Intermediate-risk Acute Lymphoblastic Leukemia: A Case Report and Review of Literature.

We described a 14-year-old girl with acute lymphoblastic leukemia who developed disseminated mucormycosis during induction therapy. Disseminated Cunninghamella elegans infection was confirmed by histopathology, microbiological culture, and metagenomic next-generation sequencing analysis of skin tissue, blood, and cerebrospinal fluid. Subsequently, the patient received a combination of liposomal amphotericin B, posaconazole, and caspofungin for antifungal treatment, but eventually died because of severe fungal pneumonia, respiratory failure, and septic shock. Moreover, case reports of pulmonary mucormycosis in children published since 1959 were reviewed. In summary, metagenomic next-generation sequencing is an effective diagnostic method for Cunninghamella with high speed and sensitivity.

Efficacy and safety of non-steroidal mineralocorticoid receptor antagonists for renal outcomes: A systematic review and meta-analysis.

BACKGROUND: Novel nonsteroidal mineralocorticoid receptor antagonists (MRAs) are noted for their potential cardiorenal benefits for patients with type 2 diabetes mellitus and chronic kidney diseases; however, the effect of this regimen on renal outcomes remains uncertain. METHODS: We performed a systematic review and meta-analysis of nonsteroidal MRAs focusing primarily on renal outcomes and safety in randomized, controlled trials. The MEDLINE, Embase, and Cochrane databases were systemically searched for trials published through April 2022. We included randomized, controlled trials assessing the effects of nonsteroidal MRAs on renal outcomes, as well as cardiovascular disease (CVD) effects in patients with chronic kidney disease (CKD). Summary estimates of risk ratios (RRs) reductions were calculated with a random-effects model. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used to evaluate the certainty of evidence. This study is registered with PROSPERO under number CRD42022335464. FINDINGS: In total, 11 trials and 1 pooled analysis including a total of 17,517 participants were enrolled. Nonsteroidal MRAs reduced renal composite endpoints by 17 % [HR = 0.83, 95 % (0.75, 0.91); low quality] with 16 % in kidney failure (high quality), 23 % in ESRD (high quality), 20 % in eGFR decreased to less than 15 mL/min/1.73 m2 (high quality), and 17 % with more than a 40 % decrease in eGFR (high quality); 14 % with cardiovascular composite endpoints [HR = 0.86, 95 % (0.78, 0.94); moderate quality]; and 13 % of all-cause mortality [HR = 0.87, 95 % (0.76, 0.98); moderate quality]. Nonsteroidal MRAs were also associated with additional benefits in lowering UACR levels (moderate quality) and lowering BP levels (moderate quality) compared with the control groups. However, nonsteroidal MRAs did not show a statistically significant effect on the risk of renal death (moderate quality), hospitalization for any cause (moderate quality) or change in GFR (low quality). Regarding safety, there was no significant difference in the risk of adverse events between the participants receiving nonsteroidal MRAs and the control group. INTERPRETATION: Nonsteroidal MRAs had a statistically beneficial effect on reducing the risk of the composite kidney outcome, the composite of cardiovascular outcomes, and all-cause mortality. Nonsteroidal MRAs were also associated with benefits of proteinuria remission and blood pressure lowering. Although these findings provided positive evidence for the use of nonsteroidal MRAs for cardiorenal protection in patients with or without CKD, the quality of this evidence is potentially uncertain.

Comprehensive analyses of a tumor-infiltrating lymphocytes-related gene signature regarding the prognosis and immunologic features for immunotherapy in bladder cancer on the basis of WGCNA.

Tumor-infiltrating lymphocyte (TIL) is a class of cells with important immune functions and plays a crucial role in bladder cancer (BCa). Several studies have shown the clinical significance of TIL in predicting the prognosis and immunotherapy efficacy. TIL-related gene module was screened utilizing weighted gene coexpression network analysis. We screened eight TIL-related genes utilizing univariate Cox regression analysis, least absolute shrinkage and selection operator (LASSO) Cox regression analysis, and multivariate Cox regression analysis. Then, we established a TIL-related signature model containing the eight selected genes and subsequently classified all patients into two groups, that is, the high-risk as well as low-risk groups. Gene mutation status, prognosis, immune cell infiltration, immune subtypes, TME, clinical features, and immunotherapy response were assessed among different risk subgroups. The results affirmed that the TIL-related signature model was a reliable predictor of overall survival (OS) for BCa and was determined as an independent risk factor for BCa patients in two cohorts. Moreover, the risk score was substantially linked to age, tumor staging, TNM stage, and pathological grade. And there were different mutational profiles, biological pathways, immune scores, stromal scores, and immune cell infiltration in the tumor microenvironment (TME) between the two risk groups. In particular, immune checkpoint genes' expression was remarkably different between the two risk groups, with patients belonging to the low-risk group responding better to immune checkpoint inhibition (ICI) therapy. In conclusion, our study demonstrates that the TIL-related model was a reliable signature in anticipating prognosis, immune status, and immunotherapy response, which can help in screening patients who respond to immunotherapy.

Hsa_circ_0102485 inhibits the growth of cancer cells by regulating the miR-188-3p/ARID5B/AR axis in prostate carcinoma.

BACKGROUND: Studies have shown that circular RNAs (circRNAs) have significant potential as novel molecular markers for the diagnosis, treatment, and prognosis of prostate carcinoma (PCa). However, the role and mechanism of circRNA hsa_circ_0102485 in PCa remains unclear. MATERIALS & METHODS: The real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to quantify hsa_circ_0102485 expression in PCa. The potential mechanisms and roles of hsa_circ_0102485 in tumor growth were explored using dual-luciferase-reporter and subcutaneous-xenograft assays, rescue experiments, and immunohistochemical staining. Clinical correlations were assessed by tissue-on-a-chip in-situ hybridization and Fisher's exact test. RESULTS: Hsa_circ_0102485 expression was decreased in PCa, and overexpression of hsa_circ_0102485 suppressed the proliferation, metastasis, invasion, and antiapoptotic abilities of PCa cells. MicroRNA 188-3p (MiR-188-3p) is a direct target of hsa_circ_0102485, and cotransfection of hsa_circ_0102485 in PCa cells overexpressing miR-188-3p inhibited its promotive effects. Hsa_circ_0102485 indirectly promotes the expression of AT-rich interaction domain 5B (ARID5B) and androgen receptor (AR) by sponging miR-188-3p and inhibiting PCa cell growth. Correlation analysis showed that hsa_circ_0102485 expression in PCa was not significantly correlated with the age, International Society of Urologic Pathologists (ISUP) grade, Gleason score, or lymph node metastasis status of PCa patients. CONCLUSION: Hsa_circ_0102485 plays an inhibitory role in PCa by regulating the Mir-188-3p/ARID5B/AR axis and may be a potential diagnostic biomarker and therapeutic target for PCa that requires further study.

Clinicopathological and Prognostic Value of Necroptosis-Associated lncRNA Model in Patients with Kidney Renal Clear Cell Carcinoma.

Background: Necroptosis, a recently identified type of programmed necrotic cell death, is closely related to the tumorigenesis and development of cancer. However, it remains unclear whether necroptosis-associated long noncoding RNAs (lncRNAs) can be used to predict the prognosis of kidney renal clear cell carcinoma (KIRC). This work was designed to probe the possible prognostic worth of necroptosis-associated lncRNAs along with their impact on the tumor microenvironment (TME) in KIRC. Methods: The Cancer Genome Atlas (TCGA) database was used to extract KIRC gene expression and clinicopathological data. Pearson correlation analysis was used to evaluate necroptosis-associated lncRNAs against 159 known necroptosis-associated genes. To define molecular subtypes, researchers used univariate Cox regression analysis and consensus clustering, as well as clinical significance, TME, and tumor immune cells in each molecular subtype. We develop the necroptosis-associated lncRNA prognostic model using univariate Cox regression analysis and least absolute shrinkage and selection operator (LASSO) regression analysis. Patients were divided into high- and low-risk groups according to prognostic model. Moreover, comprehensive analyses, including prognostic value, gene set enrichment analysis (GSEA), immune infiltration, and immune checkpoint gene expression, were performed between the two risk groups. Finally, anticancer drug sensitivity analyses were employed for assessing associations for necroptosis-associated lncRNA expression profile and anticancer drug chemosensitivity. Results: Through univariate analysis, sixty-nine necroptosis-associated lncRNAs were found to have a significant relationship with KIRC prognosis. Two molecular clusters were identified, and significant differences were found with respect to clinicopathological features and prognosis. The segregation of patients into two risk groups was done by the constructed necroptosis-associated lncRNA model. The survival prognosis, clinical features, degree of immune cell infiltration, and expression of immune checkpoint genes of high-risk and low-risk groups were all shown to vary. Conclusions: Our study identified a model of necroptosis-associated lncRNA signature and revealed its prognostic role in KIRC. It is expected to provide a reference for the screening of KIRC prognostic markers and the evaluation of immune response.

Efficacy and safety of artesunate for patients with IgA nephropathy: a study protocol for a multicenter, double-blind, randomized, placebo-controlled trial.

BACKGROUND: IgA nephropathy is the most common glomerular disease and is a common cause of progression to end-stage renal disease in patients with kidney diseases. Proteinuria levels are critical for the prognosis of patients with IgA nephropathy, but many patients are still unable to effectively control their proteinuria levels after receiving RAAS blockers. Antimalarial drugs have shown good efficacy in the treatment of kidney disease in previous studies; however, there have been no strictly designed randomized controlled trials to confirm the clinical efficacy of artesunate for treating IgA nephropathy patients. Therefore, we designed this clinical trial to compare the effect of artesunate versus placebo in patients with IgA nephropathy. METHODS: This study is a randomized, double-blind, three-group-parallel, placebo-controlled clinical trial. One hundred and twenty eligible IgA nephropathy patients at risk of progression will be randomly divided into the artesunate 100-mg group, artesunate 50-mg group, and placebo group. Changes in proteinuria and renal function will be measured 6 months after the intervention. The levels of Gd-IgA1 and anti-Gd-IgA1 in the patient's blood will also be tested to explore the possible immune mechanisms. DISCUSSION: Clinical evidence supporting artesunate treatment of IgA nephropathy is currently lacking, and we expect that the results of this trial will provide high-quality clinical evidence for artesunate as a treatment option for IgA nephropathy in the future.

Molten salt synthesis of carbon-supported Pt-rare earth metal nanoalloy catalysts for oxygen reduction reaction.

The synthesis of nano-sized alloys of Pt and rare earth (RE) metal catalysts has been a huge challenge due to a significantly large standard reduction potential difference of Pt and RE metals and the high synthesis temperature. Pt x Y/C catalysts with an average particle size of around 21 nm, were synthesized by mixing K2PtCl4 with Y2O3 (a molar ratio of Pt : Y = 1 : 1) with a carbon support in a molten LiCl-CaH2 system by a one-step molten salt synthesis method at 600 °C. The synthesis processes of the Pt x Y/C alloys are proposed as follows: Pt nanoparticles were first obtained by the reaction of K2PtCl4 and CaH2 at 210 °C, then Y ions were preferentially reduced on the Pt nanoparticle surface by the reduction of CaH2, followed by Pt x Y alloy formation in the molten LiCl-CaH2 system at 600 °C. Molten LiCl provides a strong reducing environment and lowers the formation temperature of alloys. Pt2Gd/C and Pt2La/C were also obtained with Gd2O3 and La2O3 as the starting raw materials, respectively by using the same process. When investigated as an electrocatalyst for the oxygen reduction reaction (ORR), the half-wave potentials of Pt x RE/Cs are all more positive than that of commercial Pt/C catalyst (e.g., 0.905 V for Pt x Y/C while 0.880 V for JM Pt/C), and the nano-sized Pt x Y/C alloy shows higher electrocatalytic activity toward the ORR and preferable catalytic durability with respect to JM Pt/C catalysts. This facile synthesis method provides an effective strategy for the preparation of Pt-RE based multicomponent nanoalloys, especially in large-scale production.

Efficacy and safety of 2-micron laser versus conventional trans-urethral resection of bladder tumor for non-muscle-invasive bladder tumor: A systematic review and meta-analysis.

Aim: To compare the clinical efficacy and safety of 2-micron laser and conventional trans-urethral resection of bladder tumor (TURBT) in the treatment of non-muscle-invasive bladder tumor (NMIBT), providing evidence-based evidence for clinical treatment. Materials and Methods: PubMed, Embase, Cochrane Library, CMB, CNKI, and WanFang databases were searched since their inception until December 2021 for all eligible randomized controlled trials (RCTs) related to 2-micron laser and TURBT for treating NMIBT. Two researchers independently screened the literature, extracted outcome indicators, and assessed the risk of bias according to the inclusion and exclusion criteria. Binary and continuous variables were calculated by relative risk (RR) and mean difference (MD) with 95% confidence interval (95%CI), respectively. RevMan 5.4 and Stata 15.0 software were used for all statistical analysis. Results: A total of ten RCTs involving 1,163 patients were included: 596 cases in the 2-micron laser group and 567 cases in the TURBT group. The results of the meta-analysis revealed that 2-micron laser has advantages over the TURBT in operative duration (MD = -2.94, 95% confidence interval (CI) [-8.55, 2.68], P = 0.31), operative blood loss (MD = -19.93, 95%CI [-33.26, -6.60], P = 0.003), length of hospital stay (MD = -0.94, 95%CI [-1.38, -0.50], P < 0.001), post-operative bladder irrigation time (MD = -28.60, 95%CI [-50.60, -6.59], P = 0.01), period of catheterization days (MD = -1.07, 95%CI [-1.73, -0.40], P = 0.002), obturator nerve reflex (RR = -0.06, 95%CI [0.02, 0.15], P < 0.001), bladder perforation (RR = 0.14, 95%CI [0.06, 0.35], P < 0.001), and bladder irritation (RR = 0.30, 95%CI [0.20, 0.46], P < 0.001). There was no significant difference between the two surgical methods in post-operative urethral stricture and short-term recurrence of NMIBT. Conclusion: Compared with TURBT, 2-micron laser may be safer and more effective for NMIBT management. However, these conclusions need to be validated through more high-quality RCTs because of the quality limitations and publication bias of the included studies.

Prevalence and risk factors for mental health symptoms in community epidemic prevention workers during the postpandemic era of COVID-19 in China.

Few people have paid attention to community epidemic prevention workers in the postpandemic era of COVID-19. This study aimed to explore the prevalence and risk factors for mental health symptoms in community epidemic prevention workers during the postpandemic era. Mental health status was evaluated by the Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, Chinese Perceived Stress Scale, Insomnia Severity Index, and Maslach Burnout Inventory-General Survey. The results showed that a considerable proportion of community epidemic prevention workers reported symptoms of depression (39.7%), anxiety (29.5%), high stress (51.1%), insomnia (30.8%), and burnout (53.3%). The prevalence of depression and anxiety in community epidemic prevention workers was higher than in community residents. Among community epidemic prevention workers, short sleep duration was a risk factor for depression, anxiety, high stress and insomnia. Concurrent engagement in work unrelated to epidemic prevention and current use of hypnotics were risk factors for depression, anxiety and insomnia. Our study suggests that during the postpandemic era, the mental health problems of community epidemic prevention workers are more serious than those of community residents. Several variables, such as short sleep duration and concurrent engagement in work unrelated to epidemic prevention, are associated with mental health among community epidemic prevention workers.

Enhanced photocatalytic degradation of 4-chlorophenol under visible light over carbon nitride nanosheets with carbon vacancies.

Two-dimensional graphitic carbon nitride (g-C3N4, GCN) is considered as one of the promising visible light-responsive photocatalysts for energy storage and environmental remediation. However, the photocatalytic performance of pristine GCN is restricted by the inherent shortcomings of rapid charge carrier recombination and limited absorption of visible light. Vacancy engineering is widely accepted as the auspicious approach for boosting the photocatalytic activity of GCN-based photocatalysts. Herein, a magnesium thermal calcination method has been developed to reconstruct GCN, in which magnesium serves as a carbon etcher for introducing carbon vacancies and pores into GCN (Vc-GCN). The fabricated Vc-GCN demonstrates excellent photocatalytic performances of degrading hazardous 4-chlorophenol under visible light irradiation benefiting from the improved carrier separating and light absorption ability as well as rich reactive sites. The optimal Vc-GCN sample delivers 2.3-fold enhancement from the pristine GCN. The work provides a tactic to prepare GCN photocatalysts with controllable carbon vacancies and for a candidate for the degradation of organic pollutants from the environment.
