Abstract
Objective: To explore the difference of peripheral blood mononuclear cells (PBMC) transcripts between atopic dermatitis (AD) and healthy controls, and to screen and preliminarily validate potential biomarkers of AD. Methods: From January 2021 to May 2022, blood samples from 9 AD patients and 10 healthy controls were collected from the Dermatology and Cosmetic Center of the Third Affiliated Hospital of Chongqing Medical University, ribonucleic acid-sequencing (RNA-seq) was used to determine the transcriptome and relative expression of PBMC, the differentially expressed genes (DEGs) were analyzed by gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and protein-protein interaction networks (PPI) analysis, and the potential biomarkers were identified by quantitative real-time PCR (qRT-PCR). Results: The age of patients in the AD group [M (Q1, Q3)] was 26.50 (22.75, 30.50) years old, and the course of disease [M (Q1, Q3)] was 15 (10, 20) years,and the age of the healthy control group [M (Q1, Q3)] was 37.00 (27.75, 40.25) years old. Compared with healthy controls, 1 044 DEGs were detected in PBMC samples in AD group, including 668 up-regulated genes and 376 down-regulated genes. Differential variable splicing (AS) showed that mutually exclusive exons (46.74%) and skipped exon (31.01%) accounted for a large proportion. GO and KEGG enrichment analysis revealed that AD is closely linked to DEGs implicated in the inflammatory response and cytokine interaction and signal pathway. Comprehensive enrichment analysis and PPI analysis selected the expression of 8 candidate genes (CCL4, CCR3, CXCR5, NFKBIA, CXCL1, IL-1B, CCL20, LY96), which was confirmed by qRT-PCR and were consistent with that of RNA-seq. Conclusions: CCL4, CCR3, CXCR5, NFKBIA, CXCL1, IL-1B, CCL20 and LY96 might be potential biomarkers of AD, participating in the occurrence and development of AD.

Abstract
Diagnosis of diabetic kidney disease (DKD) mainly relies on screening the morphological variations and internal lesions of glomeruli from pathological kidney biopsy. The prominent pathological alterations of glomeruli for DKD include glomerular hypertrophy and nodular mesangial sclerosis. However, the qualitative judgment of these alterations is inaccurate and inconstant due to the intra- and inter-subject variability of pathologists. It is necessary to design artificial intelligence (AI) methods for accurate quantification of these pathological alterations and outcome prediction of DKD. In this work, we present an AI-driven framework to quantify the volume of glomeruli and degree of nodular mesangial sclerosis, respectively, based on an instance segmentation module and a novel weakly supervised Macro-Micro Aggregation (MMA) module. Subsequently, we construct classic machine learning models to predict the degree of DKD based on three selected pathological indicators via factor analysis. These corresponding modules are trained and tested on a total of 281 whole slide images (WSIs) digitized from two hospitals with different scanners. Our designed AI framework achieved inspiring results with 0.926 mIoU for glomerulus segmentation, and 0.899 F1 score for glomerulus classification in the external testing dataset. Meantime, the visualized results of the MMA module could reflect the location of the lesions. The performance of predicting disease achieved the F1 score of 0.917, which further proved the effectiveness of our AI-driven quantification of pathological indicators. Additionally, the interpretation of the machine learning model with the SHAP method showed similar accordance with the development of DKD in pathology. In conclusion, the proposed auxiliary diagnostic technologies have the feasibility for quantitative analysis of glomerular pathological tissues and alterations in DKD. Pathological quantitative indicators will also make it more convenient to provide doctors with assistance in clinical practice.

Abstract
Atopic dermatitis (AD) is a chronic, relapsing, pruritic inflammatory disease with a high prevalence, ranking as the leading non-fatal burden of skin diseases. The pathogenesis of AD involves interactions among genetic factors, impaired skin barrier function, dysbiosis, and immune dysregulation. The immune phenotype is highly heterogeneous, with the Th2-dominant immune response. AD exhibits diverse clinical phenotypes, posing challenges for the establishment of clinical diagnostic criteria and personalized management. Targeted biologic therapies focusing on Th2-type inflammatory responses and small-molecule drugs blocking inflammatory signaling pathways have significantly improved the management of the moderate or severe AD. However, the balance between efficacy and safety remains to be evaluated due to limited data. Despite significant advancement in basic and clinical research on AD in recent years, there are still many questions that need to be resolved urgently.

Abstract
Objective: To investigate and analyze the clinical features of elderly atopic dermatitis (AD) in China. Methods: Based on the National Clinical Research and Homogeneous Diagnosis and Treatment Project for Type 2 Inflammation Dermatosis, a total of 2 281 patients aged 65 years or older were enrolled from 172 grade A tertiary hospitals who were diagnosed as atopic dermatitis from June 2021 to February 2023, and their demographics, clinical feature, and disease severity, etc. were collected. Elderly AD patients were divided into groups based on gender, history of allergic diseases (with or without a personal or family history of allergic diseases), and clinical features (site of onset, AD signs) and scales were compared within the groups. Median (Q1, Q3) was used for quantitative data. Results: The age of 2 281 elderly AD patients was 73.02 (68.83, 79.62) years old, among whom there were 1 649 males (72.29%) and 632 females (27.71%). A total of 2 244 cases were recorded with the information of the onset stage, of whom 1 713 cases (76.34%) occurred in the elderly stage. A total of 2 136 cases were recorded with the information of personal or family history of allergic diseases, of which 1 076 cases (50.37%) had a personal or family history of allergic diseases, and 1 060 (49.63%) had no history of allergic diseases. Skin lesions were predominantly involved in the waist, back, buttocks, and AD signs were mainly eczema-like skin lesions on the cheek and/or scalp and/or limb extension. Patients with moderate to severe AD accounted for 60.58% (1 327 cases), moderate to severe itching accounted for 81.32% (1 781 cases). Patients with anxiety and depression accounted for 46.14% (1 011 cases) and 39.27% (860 cases), respectively. Men had a higher EASI score than women [9.67 (4.77, 19.28) vs 8.45 (3.98, 17.11), P=0.040]. EASI, HADS-anxiety and WI-NRS scores were higher in patients with history of allergic diseases than those without allergy history [ (9.79 (4.84, 19.96) vs 8.96 (4.05, 18.31), P=0.015; 7.22 (3.49, 10.00) vs 6.81 (3.12, 9.33), P=0.012; 7.64 (5.62, 9.07) vs 7.38 (5.35, 8.91), P=0.036]. Conclusion: Elderly AD patients have their own exclusive clinical manifestations, and the understanding of these characteristics is beneficial for guiding clinical development of targeted management plans. Elderly AD patients are mostly senile onset, and male patients are more than female patients, skin lesions are mainly distributed on the extended side, and the disease burden is heavy.

Abstract
PURPOSE To comprehend the etiology of diabetic retinopathy (DR), it is crucial to clarify the genetic susceptibility factors for DR. Previous studies have reported that five single nucleotide polymorphisms (SNPs), including rs9362054 (near the CEP162 gene), rs1990145 (MRPL19), rs10519765 (FMN1), rs237025 (SUMO4) and rs767649 (MIR155HG) were associated with DR. This study was conducted to elucidate the association between the five SNPs and DR in a Chinese Han population. METHODS A total of 957 individuals with type 2 diabetes mellitus (T2DM) including diabetes mellitus without retinopathy (DNR = 478), nonproliferative DR (NPDR = 384) and proliferative (PDR = 95) were recruited in this study. SNPs were genotyped using the Mass ARRAY MALDI-TOF system. The genotype and allele frequencies were determined using χ2 tests. For genotype and allele risk, odds ratios (OR) and 95% confidence intervals (CI) were calculated. Four genetic models (homozygous, heterozygous, dominant, and recessive) were used to further investigate the link between the five SNPs and DR. RESULTS There was a statistically significant difference of CEP162 rs9362054 between NPDR and DNR (P = .027, OR = 1.26, 95%CI = 1.03-1.54) and a significant association of SUMO4 rs237025 detected between PDR and DNR (P = .031, OR = 1.45, 95%CI = 1.03-2.02). The association of CEP162 rs9362054 was also observed under the dominant mode (P = .03, OR = 1.35, 95%CI = 1.03-1.77). The association of SUMO4 rs237025 was found under the heterozygous model (P = .03, OR = 1.68, 95%CI = 1.06-2.69) and the dominant model (P = .02, OR = 1.70, 95%CI = 1.08-2.67). No associations of the other three SNPs with NPDR and PDR were detected when compared with DNR under these genetic models. CONCLUSIONS This study showed that rs9362054 and rs237025 were associated with NPDR and PDR when compared with DNR, suggesting that SUMO4 may be involved in the development of PDR, while CEP162 may be associated with NPDR.

Abstract
Two polysaccharides, BCP-1 and BCP-2, were obtained from Bupleurum chinense DC. by water extraction and ultrafiltration. BCP-1 (1.04 × 105 Da) and BCP-2 (2.14 × 104 Da) were composed of Mannose, Rhamnose, Glucose, Galactose, Arabinose, and Galacturonic acid in different proportions. They both contained oligogalacturonides in their main chain. Besides, the backbone of BCP-1 was composed of 4-β-Galp and 4,6-β-Glcp, and branched at C4 of 4,6-β-Glcp. While BCP-2 contained a backbone of 3,5-α-Araf residues with branches at C3. BCP-2 effectively extended the forced swimming time, improved the glycogen reserves and antioxidant system, decreased the levels of blood urea nitrogen, lactic acid, lactate dehydrogenase and creatinine kinase expression. It alleviated physical fatigue through regulating 5'-AMP-activated protein kinase (AMPK) and Nuclear Factor erythroid 2-Related Factor 2 (Nrf2) signalling pathway in skeletal muscles. This study demonstrated that BCP-2 exhibited more effective anti-fatigue activity than BCP-1 potentially associated with its primary and higher structures.

Abstract
Increasing concerns have been raised on the health risks of parabens in the regard of their widespread applications and potential endocrine disrupting activities. In this study, four typical parabens, including methyl paraben (MeP), ethyl paraben (EtP), propyl paraben (PrP), and butyl paraben (BuP) were systematically investigated for their estrogen receptor- and steroid hormone-related endocrine disruptions using multi-level approaches. Paraben exposure promoted the proliferation of MCF-7 cells, increased the luciferase activity in MVLN cells, and induced the vitellogenin (vtg) expression in zebrafish larvae, showing the typical estrogenic effects. The in vitro protein assays further revealed that PrP and BuP could bind with two isoforms of estrogen receptors (ERs). The estrogenic activities of parabens were predicted to be positively correlated with their chemical structure complexity by using molecular docking analysis. Furthermore, the synthesis and secretion of estradiol (E2) and testosterone (T) were significantly disturbed in H295R cells and zebrafish larvae, which could be regulated by paraben-induced transcriptional disturbance in both in vitro steroidogenesis and in vivo hypothalamic-pituitary-gonadal (HPG) axis. Parabens could disturb the endocrine system by activating the ERs and disrupting the steroid hormone synthesis and secretion, suggesting their potential deleterious risks to the environment and human health.

Abstract
We examined the impact of statins on protein kinase D (PKD) activation by G protein-coupled receptor (GPCR) agonists. Treatment of intestinal IEC-18 cells with cerivastatin inhibited PKD autophosphorylation at Ser916 induced by angiotensin II (ANG II) or vasopressin in a dose-dependent manner with half-maximal inhibition at 0.2 µM. Cerivastatin treatment inhibited PKD activation stimulated by these agonists for different times (5-60 min) and blunted HDAC5 phosphorylation, a substrate of PKD. Other lipophilic statins, including simvastatin, atorvastatin, and fluvastatin also prevented PKD activation in a dose-dependent manner. Using IEC-18 cell lines expressing PKD1 tagged with EGFP (enhanced green fluorescent protein), cerivastatin or simvastatin blocked GPCR-mediated PKD1-EGFP translocation to the plasma membrane and its subsequent nuclear accumulation. Similar results were obtained in IEC-18 cells expressing PKD3-EGFP. Mechanistically, statins inhibited agonist-dependent PKD activation rather than acting directly on PKD catalytic activity since exposure to cerivastatin or simvastatin did not impair PKD autophosphorylation or PKD1-EGFP membrane translocation in response to phorbol dibutyrate, which bypasses GPCRs and directly stimulates PKC and PKD. Furthermore, cerivastatin did not inhibit recombinant PKD activity determined via an in vitro kinase assay. Using enteroids generated from intestinal crypt-derived epithelial cells from PKD1 transgenic mice as a model of intestinal regeneration, we show that statins oppose PKD1-mediated increase in enteroid area, complexity (number of crypt-like buds), and DNA synthesis. Our results revealed a previously unappreciated inhibitory effect of statins on receptor-mediated PKD activation and in opposing the growth-promoting effects of PKD1 on intestinal epithelial cells.

Abstract
The formation and evolution of adiabatic shear behaviors, as well as the corresponding mechanical properties of a near-Ti-6Al-3Nb-2Zr-1Mo (Ti-6321) alloy during dynamic compression process, were systematically investigated by the split Hopkinson pressure bar (SHPB) compression tests in this paper. Ti-6321 samples containing three types of microstructures, i.e., equiaxed microstructure, duplex microstructure and Widmanstätten microstructure, were prepared to investigate the relationship between microstructures and dynamic mechanical behaviors under different strain rates in a range from 1000 s-1 to 3000 s-1. It was found by the dynamic strain-stress relation that the Ti-6321 alloys containing equiaxed microstructure, duplex microstructure and Widmanstätten microstructure all exhibited a strong strain-hardening effect. The samples containing equiaxed microstructure exhibited a larger flow stress than samples containing duplex microstructure and Widmanstätten microstructure. The adiabatic shearing behaviors in Ti-6321 alloy are significantly influenced by different types of microstructures. The formation of adiabatic shearing bands occurs in equiaxed microstructure when the strain rate is increased to 2000 s-1. The adiabatic shear bands are formed in duplex microstructure when the strain rate reaches 3000 s-1. However, the initiation of adiabatic shear bands is found in Widmanstätten microstructure under the strain rate of 1000 s-1. The Widmanstätten microstructure shows a larger sensitivity to adiabatic shearing than the equiaxed microstructure and duplex microstructure samples.

Abstract
Membranous nephropathy is one of the most prevalent conditions responsible for nephrotic syndrome in adults. It is clinically nonspecific and mainly diagnosed by kidney biopsy pathology, with three prevalent techniques: light microscopy, electron microscopy, and immunofluorescence microscopy. Manual observation of glomeruli one by one under the microscope is very time-consuming, and there are certain differences in the observation results between physicians. This study makes use of whole-slide images scanned by a light microscope as well as immunofluorescence images to classify patients with membranous nephropathy. The framework mainly includes a glomerular segmentation module, a confidence coefficient extraction module, and a multi-modal fusion module. This framework first identifies and segments the glomerulus from whole-slide images and immunofluorescence images, and then a glomerular classifier is trained to extract the features of each glomerulus. The results are then combined to produce the final diagnosis. The results of the experiments show that the F1-score of image classification results obtained by combining two kinds of features, which can reach 97.32%, is higher than those obtained by using only light-microscopy-observed images or immunofluorescent images, which reach 92.76% and 93.20%, respectively. Experiments demonstrate that considering both WSIs and immunofluorescence images is effective in improving the diagnosis of membranous nephropathy.

Abstract
BACKGROUND cGAS-STING signaling has been primarily discovered as an important DNA sensing machinery, bridging innate immunity and adaptive immunity. Beyond its antiviral response, recent evidence expanded its complicated role in cancer therapy. METHODS UALCAN, The TCGA Wander, GEPIA, SMART, TIMER, Kaplan-Meier plotter, TCGA Data, and cBioPortal were utilized in the investigation. RESULTS We evaluated the expression of four key molecules (MB21D1, TMEM173, TBK1, and IRF3) in the cGAS-STING pathway and found that the TMEM173 gene was significantly downregulated in lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC). Not only immunostimulatory cells but also regulatory T cells were triggered by the DNA sensing pathway. With gene enrichment analysis, we revealed that cell cycle and mechanotransduction/cytoskeleton signals were most closely connected with cGAS-STING signal alterations in non-small-cell lung cancer (NSCLC). cGAS-STING signaling was robustly correlated with methylation changes, especially histone H3K4 lysine demethylase KDM5s. Transient activation of cGAS-STING was found to exert tumor surveillance effect, and inhibition of STING signaling co-opt elevated KDM5 demethylases might inadvertently worsen clinical outcomes. CONCLUSION cGAS-STING signaling and KDM5 demethylases have the potential to be used as targets for evaluating an effective immune response in the tumor microenvironment.

Abstract
Background The pathophysiological processes linked to an acute ischemic stroke (IS) can be reflected in the circulating metabolome. Amino acids (AAs) have been demonstrated to be one of the most significant metabolites that can undergo significant alteration after a stroke. Methods We sought to identify the potential biomarkers for the early detection of IS using an extensive targeted technique for reliable quantification of 27 different AAs based on ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). A cohort with 216 participants was enrolled, including 70 mild to moderate ischemic stroke patients (National Institutes of Health Stroke Scale < 15, MB group), 76 stroke mimics (MM group) and 70 healthy controls (NC group). Results It was found that upon comparing MB and MM to control patients, AAs shifts were detected via partial least squares discrimination analysis (PLS-DA) and pathway analysis. Interestingly, MB and MM exhibited similar AAs pattern. Moreover, ornithine, asparagine, valine, citrulline, and cysteine were identified for inclusion in a biomarker panel for early-stage stroke detection based upon an AUC of 0.968 (95% CI 0.924-0.998). Levels of ornithine were positively associated with infract volume, 3 months mRS score, and National Institutes of Health Stroke Scale (NIHSS) score in MB. In addition, a metabolites biomarker panel, including ornithine, taurine, phenylalanine, citrulline, cysteine, yielded an AUC of 0.99 (95% CI 0.966-1) which can be employed to effectively discriminate MM patients from control. Conclusion Overall, alternations in serum AAs are characteristic metabolic features of MB and MM. AAs could serve as promising biomarkers for the early diagnosis of MB patients since mild to moderate IS patients were enrolled in the study. The metabolism of AAs can be considered as a key indicator for both the prevention and treatment of IS.

Abstract
BACKGROUND AND PURPOSE In patients with Moyamoya disease, the relationship between preoperative hemodynamic status and prognosis after encephalo-duro-arterial synangiosis (EDAS) surgery was unclear. We aimed to explore the value of the preoperative hemodynamic status acquired by cine phase-contrast MR imaging in predicting collateral formation and clinical outcomes after EDAS surgery in patients with Moyamoya disease. MATERIALS AND METHODS Participants with Moyamoya disease were prospectively recruited and underwent preoperative phase-contrast MR imaging. All participants were classified into good and poor groups according to the collateral formation after EDAS surgery. On the basis of the change in the mRS system, participants were classified into the improved mRS group and the poor response group. Hemodynamic status including mean velocity, peak velocity, and blood volume flow of the superficial temporal artery was compared between groups. Logistic regression was performed to relate the phase-contrast MR imaging parameters to collateral formation and clinical outcomes. RESULTS A total of 45 patients with Moyamoya disease with unilateral EDAS surgery were finally included. Mean velocity, peak velocity, and blood volume flow of the ipsilateral superficial temporal artery were significantly greater in patients with good collateral formation compared with those with poor collateral formation (P = .011, .004, and .013, respectively). The mean velocity, peak velocity, and blood volume flow were independently associated with postoperative collateral formation after adjusting for confounding factors. Furthermore, the peak velocity of the ipsilateral superficial temporal artery was also significantly associated with improvement of the mRS score. CONCLUSIONS Good hemodynamic status of the ipsilateral superficial temporal artery as a donor artery evaluated by phase-contrast MR imaging was significantly associated with better collateral formation and improved mRS after EDAS surgery in patients with Moyamoya disease.

Abstract
The diverse applications of porphyrin-based nano-sized metal-organic frameworks (NMOFs) lead to great exposure risks to human and environment. Understanding the cellular biological effects (such as toxicity, distribution, and localization) of porphyrinic NMOFs is a prerequisite to the assessment of their health risk. However, the characteristics of distribution, localization, and immune response induced by porphyrinic NMOFs have not been studied yet. Here, we report the size-dependent biological effects of porphyrinic NMOFs under sublethal dose. Various sizes of PCN-224 (30, 90, and 180 nm) were taken as model porphyrinic NMOFs. We found that 30 nm PCN-224 gave the highest uptake content, followed by 90 and 180 nm PCN-224. The mechanism for uptake was clathrin-mediated for 30 and 90 nm PCN-224, but clathrin- and glycosylphosphatidylinositol-mediated for 180 nm PCN-224. All PCN-224 were localized in lysosome with size-dependent velocity of colocalization transport. 30 nm PCN-224 induced the highest released cytokines than 90 and 180 nm PCN-224 accompanied with the activation of NF-κB pathway. This work reveals the mechanisms for the endocytosis of PCN-224 and the release of cytokine induced by PCN-224, which is helpful for the health risk assessment of NMOFs.

Abstract
Herpes zoster (HZ) is a common viral disease that mainly affects the elderly population with a rising incidence. The occurrence of postherpetic neuralgia (PHN) is the dominant and thorny complication, which thus further aggravates the disease burden. Vaccination and clinical application of small molecules and biologics for certain diseases are identified as new risk factors for the development of HZ development. HZ vaccination has emerged as a pivotal prevention measure against the occurrence of HZ. Refining the diagnosis and early standardized antiviral treatment of HZ is the key to improve standardized management strategy.

EXPERIMENTAL DESIGN We curated a total of 139 advanced non-small cell lung cancer (NSCLC) patients who harbored wild-type TP53 (TP53wt) or mutated TP53 (TP53mut) based on next-generation sequencing (NGS) to analyze multiple-dimensional data types, including tumor mutation burden (TMB), programmed death receptor ligand 1 (PD-L1) expression, co-mutant alterations, hotspot mutations distribution, and therapy response. RESULTS TP53 was evident in 125 mutations and significantly associated with male sex, adenocarcinoma differentiation, smoking history, PD-L1 tumor proportion score, and TMB level. The most frequent mutations were distributed on exon 8, but there were no distinct hotspot mutations. After outlining the co-mutation genes, it is interesting to note that DNA damage repair (DDR) genes were frequent alterations in the mutated TP53 cohort. Even though there was no significant difference between the TP53wt and TP53mut cohorts on therapy response, patients with nucleotide variation in G>T achieved a relatively higher durable clinical benefit (DCB) rate. CONCLUSIONS This real-world retrospective study suggests that molecular stratification on the basis of TP53 mutations should be deeply explored for NSCLC to optimize and modify clinical therapy choices.

Abstract
Acetate supplementation has been shown to increase milk fat yield in diets with low risk of biohydrogenation-induced milk fat depression. The interaction of acetate supplementation with specific dietary factors that modify rumen fermentation and short-chain fatty acid (FA) synthesis has not been investigated. The objective of this experiment was to determine the effect of acetate supplemented as sodium acetate at 2 dietary fiber levels. Our hypothesis was that acetate would increase milk fat production more in animals fed the low-fiber diet. Twelve lactating multiparous Holstein cows were arranged in a 4 × 4 Latin square design balanced for carryover effects with a 2 × 2 factorial arrangement of dietary fiber level and acetate supplementation with 21-d experimental periods. The high-fiber diet had 32% neutral detergent fiber and 21.8% starch, and the low-fiber diet had 29.5% neutral detergent fiber and 28.7% starch created by substitution of forages predominantly for ground corn grain. Acetate was supplemented in the diet at an average 2.8% of dry matter (DM) to provide approximately 10 mol/d of acetate as anhydrous sodium acetate. Acetate supplementation increased DM intake by 6%, with no effect on meal frequency or size. Furthermore, acetate supplementation slightly increased total-tract apparent DM digestibility and tended to increase organic matter digestibility. Acetate supplementation increased milk fat concentration and yield by 8.6 and 10.5%, respectively, but there was no interaction with dietary fiber. The increase in milk fat synthesis was associated with 46 and 85 g/d increases in the yield of de novo (<16C) and mixed source (16C) FA, respectively, with no changes in yield of preformed FA (>16C). There was a 9% increase in the concentration of milk mixed-source FA and a 7% decrease in milk preformed FA with acetate supplementation, regardless of dietary fiber level. Acetate supplementation also increased the concentrations of plasma acetate and β-hydroxybutyrate, major metabolic substrates for mammary lipogenesis. Overall, acetate supplementation increased milk fat yield regardless of dietary fiber level through an increase mostly caused by an increase in longer-chain de novo FA, suggesting stimulation of mammary lipogenesis. The heightened mammary de novo lipogenesis was supported by an increase in the concentration of metabolic substrates in plasma.

Abstract
BACKGROUND AND OBJECTIVE Current recommendations prescribe either nicardipine or labetalol as the first-line treatment for acute hypertension due to ease of use, availability, and low price. However, it is unclear if these drugs have different effectiveness and safety profiles. This systematic review and meta-analysis aimed to compare the efficacy and safety of labetalol and nicardipine in patients with acute stroke. MATERIALS AND METHODS MEDLINE via PubMed, Scopus, Embase, and Google Scholar databases were electronically searched for the eligible publications from inception until March 2022. All full-text journal papers in English which compared the efficacy of nicardipine with that of labetalol on lowering blood pressure (BP; or treating hypertension) in all subtypes of acute stroke were included. The Cochrane Collaboration tool was used to assess the risk of bias. Data were analyzed using specific statistical methods. RESULTS Following the abstract and full-text screening, this meta-analysis included five retrospective cohorts and one prospective pseudorandomized cohort. Nicardipine's effect on time at goal BP was significantly superior to that of labetalol in patients with acute stroke (0.275 standardized mean difference [SMD], 95% confidence interval [CI]: 0.112-0.438, P = 0.001). The incidence of adverse events was significantly higher in the nicardipine group than that in the labetalol group. The pooled odds ratio (OR) was 1.509 (95% CI: 1.077-2.113, I2 = 0.00%, P = 0.757). The quality of included studies was found to be low. CONCLUSION More prospective, comparative trials are needed to investigate the efficacy of BP management as well as clinical outcomes in acute stroke patients receiving continuous labetalol and nicardipine infusions.

Abstract
Both exosomes derived from neural progenitor cells (NPCs) can suppress inflammation. Whether exosomes derived from miR-21-transfected NPCs (miR-21-Exo) could be utilized to alleviate hearing loss is investigated. NPCs were transfected with lentiviral vectors overexpressing miR-21, and miR-21-Exo was purified. Morphology and exosome membrane markers were examined with nanoparticle tracking analysis, transmission electron microscopy, and Western blot. After incubation with different concentrations of miR-21-Exo, the viability of RAW 264.7 cells and the relative expressions of miR-21 and IL-10 were determined. The ischemia and reperfusion (I/R) model of C57BL/6 J mice was constructed, and the treatment benefit of miR-21-Exo was revealed by the auditory brainstem response (ABR) test. Immunofluorescence staining of caspase-3 and parvalbumin was used to detect apoptosis hair cells in the cochlea, and Western blot was utilized to detect the relative expressions of P53 and inflammatory cytokines in the cochlea. Isolated exosomes were confirmed by the size of 96 ± 25 nm, single membrane, and positive expression of CD9 and Tsg101. Upregulated miR-21 expression was detected in miR-21-transfected NPCs and miR-21-Exo. miR-21-Exo incubation demonstrated no cytotoxicity but upregulated miR-21 and IL-10 expressions in RAW 264.7 cells. The administration of miR-21-Exo inhibited the increased ABR threshold under 8, 16, and 32 kHz frequencies in cochlea-I/R injury mice and diminished the mean fluorescent intensity of caspase-3/parvalbumin. Moreover, miR-21-Exo treatment increased the IL-10 expression and prevented the increased TNF-α and IL-1β expressions in the cochlea of I/R mice both in mRNA and protein levels. Inner ear administration of miR-21-Exo effectively improved hearing damage caused by I/R.

Abstract
The wide utilization of nano-sized metal-organic frameworks (NMOFs) leads to inevitable health risks to humans. Previous studies on health risks of NMOFs mainly focus on the cytotoxic tests of typical NMOFs,but lack sufficient studies on the effects of physiochemical characteristics of NMOFs on the cytotoxicity and the related mechanisms. Here, four kinds of Zr-based porphyrinic NMOFs (PCNs), including spherical 30, 90, and 180 nm PCN-224 and rod-like 90 nm PCN-222, were taken as a proof of the concept to investigate the effects of the size and shape of NMOFs on the cytotoxicity and related mechanisms to macrophages. The 30 nm spherical PCN-224 induced significant rupture of cell membrane and dissolved in lysosome, leading to the most significant cell necrosis among the studied other nano-sized PCNs. However, other studied PCNs showed insignificant membrane rupture and their dissolution in lysosome. Furthermore, the 90 nm-sized PCN-224 led to much more significant cell necrosis by inducing lysosome damage and inhibiting of autophagy flux than the rod-like 90 nm PCN-222. These findings reveal the size- and shape-dependent cytotoxicity of PCNs and the related mechanisms and are helpful to the assessment of the potential health risks of NMOFs and the safe application of NMOFs.

Abstract
Biohydrogenation-induced milk fat depression (MFD) is a reduction in milk fat synthesis caused by bioactive fatty acids (FA) produced during altered ruminal microbial metabolism of unsaturated FA. The methionine analog 2-hydroxy-4-(methylthio)butanoate (HMTBa) has been shown to reduce the shift to the alternate biohydrogenation pathway and maintain higher milk fat yield in high-producing cows fed diets lower in fiber and higher in unsaturated FA. The objective of this experiment was to verify the effect of HMTBa on biohydrogenation-induced MFD and investigate associated changes in rumen environment and fermentation. Twenty-two rumen cannulated high-producing Holstein cows [168 ± 66 d in milk; 42 ± 7 kg of milk/d (mean ± standard deviation)] were used in a randomized design performed in 2 blocks (1 = 14 cows, 2 = 8 cows). Treatments were control (corn carrier) and HMTBa (0.1% of diet dry matter). The experiment included a 7-d covariate period followed by 3 phases that fed diets with increasing risk of MFD. The diet during the covariate and low-risk phase (7 d) was 32% neutral detergent fiber with no additional oil. The diet during the moderate-risk phase (17 d) was 29% neutral detergent fiber with 0.75% soybean oil. Soybean oil was increased to 1.5% for the last 4 d. The statistical model included the random effect of block and time course data were analyzed with repeated measures including the random effect of cow and tested the interaction of treatment and time. There was no effect of block or interaction of block and treatment or time. There was no overall effect of treatment or treatment by time interaction for dry matter intake, milk yield, and milk protein concentration and yield. Overall, HMTBa increased milk fat percent (3.2 vs. 3.6%) and yield (1,342 vs. 1,543 g/d) and there was no interaction of treatment and dietary phase. Additionally, HMTBa decreased the concentration of trans-10 18:1 in milk fat and rumen digesta. Average total ruminal concentration of volatile FA across the day and total-tract dry matter and fiber digestibility were not affected by HMTBa, but HMTBa increased average rumen butyrate and decreased propionate concentration and increased total protozoa abundance. Additionally, HMTBa increased the fractional rate of α-linoleic acid clearance from the rumen following a bolus predominantly driven by a difference in the first 30 min. Plasma insulin was decreased by HMTBa. In conclusion, HMTBa prevented the increase in trans FA in milk fat associated with MFD through a mechanism that is independent of total volatile FA concentration, but involves modification of rumen biohydrogenation. Decreased propionate and increased butyrate and ruminal protozoa may also have functional roles in the mechanism.

Abstract
Patients with co-occurring mutations in LRP1B and FAT1/2/3/4 revealed a relatively higher TMB level compared with single LRP1B and FAT mutation groups. Patients with EGFR mutation were prone to produce a weaker TMB level and less co-occurring mutation in LRP1B and FAT1/2/3/4, which might be correlated with immunosuppressive tumor microenvironment. LRP1B and FAT members showed specifically enriched T cell-inflamed genes and the co-occurring mutant TP53 status in NSCLC patients who harbor LRP1B/FAT comutations.
Background Preliminary investigation revealed that Low-density lipoprotein receptor-related protein 1b (LRP1B) and FAT atypical cadherin (FAT) family mutation might serve as immune regulators under certain tumor microenvironment. Experimental design We curated a total of 70 non-small cell lung cancer (NSCLC) patients who harbored alterations in LRP1B and/or FAT family (FAT1/2/3/4) based on next-generation sequencing (NGS) to analyze multiple-dimensional data types, including comutant status, tumor mutation burden (TMB), programmed death receptor ligand 1 (PD-L1) expression, T cell-inflamed gene expression profiling (GEP) and therapy response. Results 20 patients with co-occurring mutations in LRP1B and FAT1/2/3/4 revealed a relatively higher TMB level of 17.05 mut/Mb compared with 7.60 mut/Mb and 8.80 mut/Mb in single LRP1B and FAT mutation groups, respectively. LRP1B and FAT members showed specifically enriched T cell-inflamed genes and the co-occurring mutant TP53 status in NSCLC patients who harbor LRP1B/FAT comutations. Conclusions This work provides evidence that co-occurring mutations of LRP1B and FAT in NSCLC may serve as a group of potential predictive factors in guiding immunotherapy on the basis of their association with TMB status.

Abstract
Antimicrobial materials can prevent microbial infection and affect the beauty and structure of interior walls. Herein, a hybrid material silver/chitosan-sepiolite (Ag/5CTs-Sep) with antimicrobial activities was prepared via impregnation. Its antimicrobial properties were investigated via the disk diffusion method. Results showed that the width of inhibition zone of Ag/5CTs-Sep against Staphylococcus aureus (S. aureus), Escherichia coli (E. coli) and Aspergillus niger reached 58.15, 32.95 and 35.18 mm, respectively. The Sep was a suitable carrier for increasing thermal stability and antimicrobial durability, and chitosan improved the dispersion of silver to enhance antimicrobial activities. In addition, characterization indicated that the modification of Sep by CTs can promote the formation of lattice oxygen in Ag/5CTs-Sep, which can induce a high reactive oxygen species (ROS) content, causing the death of microbials. The antifungal mechanism revealed that the death of Aspergillus niger was due to Ag/5CTs-Sep that induced the production of high ROS level and damaged cell membrane. Moreover, Ag/5CTs-Sep possessed low cytotoxicity, and an applied test of the water-based coatings showed that the addition of Ag/5CTs-Sep could both effectively inhibit microorganisms and meet the performance standards for water-based coatings. This work may provide new guidance for the design and application of antibacterial materials.

Abstract
All-solid-state sodium batteries (ASSSBs) are promising candidates for grid-scale energy storage. However, there are no commercialized ASSSBs yet, in part due to the lack of a low-cost, simple-to-fabricate solid electrolyte (SE) with electrochemical stability towards Na metal. In this work, we report a family of oxysulfide glass SEs (Na3PS4−xOx, where 0 < x ≤ 0.60) that not only exhibit the highest critical current density among all Na-ion conducting sulfide-based SEs, but also enable high-performance ambient-temperature sodium-sulfur batteries. By forming bridging oxygen units, the Na3PS4−xOx SEs undergo pressure-induced sintering at room temperature, resulting in a fully homogeneous glass structure with robust mechanical properties. Furthermore, the self-passivating solid electrolyte interphase at the Na|SE interface is critical for interface stabilization and reversible Na plating and stripping. The new structural and compositional design strategies presented here provide a new paradigm in the development of safe, low-cost, energy-dense, and long-lifetime ASSSBs. Single sodium-ion solid electrolyte that meets the requirements of practical applications is difficult to design. Here, the authors show how kinetic stability via the creation of a self-passivating solid electrolyte interphase allows a homogenous glass solid electrolyte to exhibit remarkable electrochemical stability with sodium metal.

Abstract
Background Cytoplasmic activation/proliferation-associated protein-1 (CAPRIN1) plays an important role in carcinogenesis, whereas its role in laryngeal squamous cell carcinoma remains unclear. This study was designed to investigate the roles of CAPRIN1 in glycolysis and chemoresistance and its underlying mechanisms in laryngeal squamous cell carcinoma. Methods Cell viability was evaluated by using CCK-8 and colony formation assays. qRT-PCR, Western blotting, and immunohistochemistry were used to determine the expressions of target genes. Gene knockdown and overexpression cell lines were constructed by performing transfection of siRNAs and plasmids, respectively. Luciferase reporter assay, RNA pull-down, and RNA immunoprecipitation assays were applied to evaluate the RNA-protein interactions. The Kaplan-Meier analysis was performed to evaluate the relationship between gene expression and overall survival rate. Results An elevation of CAPRIN1 was identified to be associated with chemoresistance and poor prognosis in patients with laryngeal cancer. The increase of CAPRIN1 promoted glycolysis and chemoresistance, whereas the knockdown of CAPRIN1 inhibited glycolysis and chemoresistance in laryngeal cancer cells. The underlying mechanistic investigation revealed that CAPRIN1 promoted glycolysis and chemoresistance of laryngeal cancer cells by the regulation of Zic Family Member 5 (ZIC5). Conclusion CAPRIN1 promoted laryngeal squamous cell carcinoma glycolysis and chemoresistance by the regulation of ZIC5.

Abstract
BACKGROUND Low-temperature plasma ablation (LTPA) is an emerging technique for laryngeal leukoplakia (LL). OBJECTIVE To initially observe the healing process of trauma after LTPA for LL. MATERIALS AND METHODS Seventeen patients who underwent LTPA for LL were collected, and the degrees of wound healing were analyzed. RESULTS Only 1 patient in who dysbiosis of the pharyngeal flora was induced by self-administered hormone nebulization treatment during the follow-up period. In the remaining patients, the wound healing was characterized by a crater-shaped defect on the vocal folds surface with pseudo-membranes, congestion, and mild edema on postoperative day 1. These symptoms became worse on postoperative day 7. On postoperative day 15, the pseudo-membrane was fully formed and some patients had granulomatous swelling of the vocal cords. These symptoms became better and better on postoperative day 30 and day 45. On postoperative day 60, the mucosa of the vocal folds had essentially returned to normal. On postoperative day 90, the vocal folds morphology and function had recovered well. CONCLUSION It takes 2-3 months for the wound to heal completely after LTPA for LL. SIGNIFICANCE A proper understanding of the wound healing process can reduce unnecessary surgical and pharmacologic interventions and avoid excessive treatment.

Abstract
Understanding the toxicity of metal-organic frameworks (MOFs) is important for improving their biocompatibility in further applications, especially the hematotoxicity of MOFs due to the unavoidable contact of MOFs with blood in biomedical science. Here we report the hematotoxicity and underlying mechanisms of nano-sized zeolite-like MOFs ZIF-8 and ZIF-67 because of their wide applications in biomedical science. ZIF-67 induced significant hemolysis of red blood cell (Rb) through breaking the structure of membrane due to the generation of free radicals, whereas ZIF-8 was hematocompatible. ZIF-67 was thus internalized by Rb and then bound with hemoglobin via hydrogen bond and van der Waals force, which influenced the structure and function of hemoglobin in accompany with heme release. These findings reveal the detailed mechanism of the hematological effects of MOFs on Rb and are helpful to the assessment of the toxicity and potential health risks of MOFs and the design of biosafe MOFs for biomedical applications.

Abstract
BACKGROUND AND OBJECTIVES Direct immunofluorescence (DIF) is an important medical evaluation tool for renal pathology. In the DIF images, the deposition appearances and locations of immunoglobulin on glomeruli involve immunological characteristics of glomerulonephritis and thus can be used to aid in the identification of glomerulonephritis disease. Manual classification to such deposition patterns is time consuming and may lead to significant inter and intra operator variances. We wanted to automate the identification and fusion of deposition location and deposition appearance to assist physicians in achieving immunofluorescence reporting. METHODS In this paper, we propose a framework that consists of a pre-segmentation module and a classification module for automatically segmenting glomerulus object and classifying the deposition pattern of immunoglobulin on glomerulus object. For the pre-segmentation module, the glomerulus object is segmented out from the acquired DIF images using a segmentation network, which excludes other tissues and makes the classification module focus on the glomerulus. For the classification module, two branches of classifying deposition region and appearance, respectively, are formed by using multiple attentions convolutional neural network (MANet) based on the segmented images, and the classification results of the two pre-trained classification networks are fused with labels. RESULTS Experimental results show that the proposed framework achieves a high classification performance with an accuracy of 98% and 95% in terms of deposition region and appearance, respectively. The label fusion of deposition appearance and deposition classification is achieved with high accuracy based on well-trained classification. CONCLUSIONS The data show that automated and accurate patterned immunofluorescence report generation is achieved, which can effectively help improve the diagnosis of autoimmune kidney disease.

Abstract
Acute myeloid leukemia (AML) is a heterogeneous disease associated with various alterations in T cell phenotype and function leading to an abnormal cell population, ultimately leading to immune exhaustion. However, restoration of T cell function allows for the execution of cytotoxic mechanisms against leukemic cells in AML patients. Therefore, long-term disease control, which requires multiple therapeutic approaches, includes those aimed at the re-establishment of cytotoxic T cell activity. AML treatments that harness the power of T lymphocytes against tumor cells have rapidly evolved over the last 3 to 5 years through various stages of preclinical and clinical development. These include tissue-infiltrated lymphocytes (TILs), bispecific antibodies, immune checkpoint inhibitors (ICIs), chimeric antigen receptor T (CAR-T) cell therapy, and tumor-specific T cell receptor gene-transduced T (TCR-T) cells. In this review, these T cell-based immunotherapies and the potential of TILs as a novel antileukemic therapy will be discussed.

Abstract
Background Despite improvements in diagnosis and treatment, lung cancer is one of the most lethal human diseases, with a dismal 5-year relative survival rate of only 5% for patients diagnosed with advanced metastatic disease. Accumulating evidence supports that epigenetic aberration of histone demethylase-KDM5 subfamily is linked to human pan-cancer. However, the detailed functions of KDM5 proteins in lung cancer, especially in non-small-cell lung cancer (NSCLC), remain poorly understand. Methods UALCAN, GEPIA, Kaplan-Meier plotter, cBioPortal, TIMER, TISIDB, and STRING databases were utilized in this investigation. Results We detected varying degrees of gene mutations of KDM5 subfamily members and found that KDM5B/C were remarkably overexpressed in LUAD and LUSC compared to normal tissues. Different from KDM5D, positive relationship was shown between overall survival and mRNA expression of KDM5A/B/C in lung cancer. We determined that KDM5A/B/C expression levels were positively correlated with CD4+ T cells infiltration, especially immunological markers of Tregs and Th17 cells. Moreover, LUAD and LUSC were separately rich in inflammatory and wound healing subtypes after immunogenomics analyzing with respect to KDM5 subfamily overexpression. And with their 120 co-expressed genes, we revealed that nucleocytoplasmic transport and cellular protein localization-related genes were closely connected to KDM5 subfamily alterations, next to chromatin remodeling genes. Conclusion We formulated the immune-infiltrating and prognostic value of KDM5 subfamily and highlighted its promising role in immune-inflammatory interaction with tumour microenvironment in NSCLC.

Abstract
Familial exudative vitreoretinopathy (FEVR) is a severe retinal vascular disease that causes blindness. FEVR has been linked to mutations in several genes associated with inactivation of the Norrin/β-catenin signaling pathway, but these account for only approximately 50% of cases. We report that mutations in α-catenin (CTNNA1) cause FEVR by overactivating the β-catenin pathway and disrupting cell adherens junctions. We identified 3 heterozygous mutations in CTNNA1 (p.F72S, p.R376Cfs*27, and p.P893L) by exome sequencing and further demonstrated that FEVR-associated mutations led to overactivation of Norrin/β-catenin signaling as a result of impaired protein interactions within the cadherin-catenin complex. The clinical features of FEVR were reproduced in mice lacking Ctnna1 in vascular endothelial cells (ECs) or with overactivated β-catenin signaling by an EC-specific gain-of-function allele of Ctnnb1. In isolated mouse lung ECs, both CTNNA1-P893L and F72S mutants failed to rescue either the disrupted F-actin arrangement or the VE-cadherin and CTNNB1 distribution. Moreover, we discovered that compound heterozygous Ctnna1 F72S and a deletion allele could cause a similar phenotype. Furthermore, in a FEVR family, we identified a mutation of LRP5, which activates Norrin/β-catenin signaling, and the corresponding knockin mice exhibited a partial FEVR-like phenotype. Our study demonstrates that the precise regulation of β-catenin activation is critical for retinal vascular development and provides new insights into the pathogenesis of FEVR.

Abstract
Protein tyrosine phosphatases (PTPs) are modulators of cellular functions such as differentiation, metabolism, migration, and survival. PTPs antagonize tyrosine kinases by removing phosphate moieties from molecular signaling residues, thus inhibiting signal transduction. Two PTPs, SHP-1 and SHP-2 (SH2 domain-containing phosphatases 1 and 2, respectively) and another inhibitory phosphatase, SH2 domain-containing inositol phosphatase (SHIP), are essential for cell function, which is reflected in the defective phenotype of mutant mice. Interestingly, SHP-1, SHP-2, and SHIP mutations are identified in many cases of human leukemia. However, the impact of these phosphatases and their mutations regarding the onset and progression of leukemia is controversial. The ambiguity of the role of these phosphatases imposes challenges on the development of targeting therapies for leukemia. This fundamental problem, confronted by the expanding investigational field of leukemia, will be addressed in this review, which will include a discussion of the molecular mechanisms of SHP-1, SHP-2, and SHIP in normal hematopoiesis and their role in leukemia. Clinical development of leukemic therapies achieved by targeting these phosphatases will be addressed as well.

Abstract
In the diagnosis of chronic kidney disease, glomerulus as the blood filter provides important information for an accurate disease diagnosis. Thus automatic localization of the glomeruli is the necessary groundwork for future auxiliary kidney disease diagnosis, such as glomerular classification and area measurement. In this paper, we propose an efficient glomerular object locator in kidney whole slide image(WSI) based on proposal-free network and dynamic scale evaluation method. In the training phase, we construct an intensive proposal-free network which can learn efficiently the fine-grained features of the glomerulus. In the evaluation phase, a dynamic scale evaluation method is utilized to help the well-trained model find the most appropriate evaluation scale for each high-resolution WSI. We collect and digitalize 1204 renal biopsy microscope slides containing more than 41000 annotated glomeruli, which is the largest number of dataset to our best knowledge. We validate the each component of the proposed locator via the ablation study. Experimental results confirm that the proposed locator outperforms recently proposed approaches and pathologists by comparing F 1 and run time in localizing glomeruli from WSIs at a resolution of 0.25 μm/pixel and thus achieves state-of-the-art performance. Particularly, the proposed locator can be embedded into the renal intelligent auxiliary diagnosis system for renal clinical diagnosis by localizing glomeruli in high-resolution WSIs effectively.

Abstract
PURPOSE Genetic factors have been studied to be associated with diabetic retinopathy (DR). This study aimed to investigate the association between the polymorphisms in the osteoproterin (OPG) gene and DR in a Han Chinese population. METHODS There were 475 patients with diabetic retinopathy (DR), 478 type 2 diabetes mellitus without retinopathy (DNR) and 469 healthy controls collected in this study. OPG single-nucleotide polymorphisms (SNPs) rs2073618 and rs3134069 were genotyped by Mass ARRAY MALDI-TOF system. The genotype and allele frequencies were evaluated using the χ2 tests. Odds ratio (OR) and 95% confidence intervals (95% CI) were calculated for the risk of genotype and allele. RESULTS There was a statistically significant difference for OPG SNP rs3134069 between DR cases and healthy controls in the allelic model (P = .036, OR = 1.33, 95% CI = 1.02-1.73). The C allele frequency of this polymorphism was 0.154 in the DR cases, whereas it was 0.120 in healthy controls, suggesting a risk effect for DR. SNP rs3134069 had a significant association with DR in the dominant model (P = .038, OR = 1.37, 95% CI = 1.02-1.84), indicating that the CC/AC genotype was more likely to suffer from DR. For rs2073618, no significant difference was identified in the allelic model (P = .632, OR = 0.95, 95% CI = 0.78-1.16) and the four genetic models. CONCLUSIONS This study showed that OPG SNP rs3134069 was associated with DR in the dominant model, suggesting that the OPG gene variant may be involved in the development of DR.

Abstract
In the present work, the localized features of adiabatic shear bands (ASBs) of our recently designed damage tolerance α+β dual-phase Ti alloy are investigated by the integration of electron backscattering diffraction and experimental and theoretical Schmid factor analysis. At the strain rate of 1.8 × 104 s-1 induced by a split Hopkinson pressure bar, the shear stress reaches a maximum of 1951 MPa with the shear strain of 1.27. It is found that the α+β dual-phase colony structures mediate the extensive plastic deformations along α/β phase boundaries, contributing to the formations of ASBs, microvoids, and cracks, and resulting in stable and unstable softening behaviors. Moreover, the dynamic recrystallization yields the dispersion of a great amount of fine α grains along the shearing paths and in the ASBs, promoting the softening and shear localization. On the contrary, low-angle grain boundaries present good resistance to the formation of cracks and the thermal softening, while the non-basal slipping dramatically contributes to the strain hardening, supporting the promising approaches to fabricate the advanced damage tolerance dual-phase Ti alloy.

Abstract
Probing the interaction of nanomaterials (NMs) with proteins is the basic step for biological safety assessment. Many physiochemical factors of NMs play important roles in binding with proteins as they determine the binding process. Among them, the chirality-related biological effects and nanotoxicology have not been fully understood. As NMs are mainly exposed to human circulatory system with intentional or unintentional exposure, understanding the interaction mechanism of plasma functional proteins with chiral NMs is of great importance. Herein, we show the interaction of chiral gold nanoclusters (AuNCs), L- and D-cysteine coated AuNC (i.e., L-AuNC and D-AuNC, respectively) with human coagulation factor XII (FXII, an important plasma zymogen initiating the inner coagulation system). D-AuNC exhibited weak binding affinity for FXII, induced FXII aggregation due to significant conformational change, which then activated the FXII for further cleavage. In contrast to D-AuNC, the binding affinity of L-AuNC for FXII was strong and their bioconjugate was quite stable without aggregation. L-AuNC induced the structural change and autoactivation of FXII to a lower extent. Moreover, the enzymatic activity of FXIIa (the activated form of FXII) was influenced upon incubation with L- AuNCs and D-AuNCs with different molecular mechanisms. The finding will expand the understanding of the nanobiological effects of chiral NMs and suggest the potential application in nanomedicine.

Abstract
The tremendous potential for graphene quantum dots (GQDs) in biomedical applications has led to growing concerns of their health risks in human beings. However, present studies mainly focused on oxidative stress, apoptosis, and other general toxicity effects; the knowledge on the developmental toxicity and the related regulatory mechanisms is still far from sufficient. Our study revealed the development retardation of mouse embryonic stem cells (mESCs) caused by GQDs with a novel DNA methylation epigenetic mechanism. Specifically, GQDs were internalized into cells mainly via energy-dependent endocytosis, and a significant fraction of internalized GQDs remained in the cells even after a 48-h clearance period. Albeit with unobservable cytotoxicity or any influences on cell pluripotency, significant retardation was found in the in vitro differentiation of the mESCs into embryoid bodies (EBs) with the upregulation of Sox2 levels in GQD pretreatment groups. Importantly, this effect could be contributed by GQD-induced inhibition in CpG methylation of Sox2 through altering methyltransferase and demethyltransferase transcriptional expressions, and the demethyltransferase inhibitor, bobcat339 hydrochloride, reduced GQD-induced upregulation of Sox2. The current study first demonstrated that GQDs compromised the differentiation program of the mESCs, potentially causing development retardation. Exposure to this nanomaterial during gestation or early developmental period would cause adverse health risks and is worthy of more attention.

Abstract
Background: Familial exudative vitreoretinopathy (FEVR) is an inheritable retinal vascular disease, which often leads to severe vision loss and blindness in children. However, reported mutations can only account for 50-60% of patients with FEVR. The purpose of this study was to identify novel frizzled class receptor 4 (FZD4) and Norrin cystine knot growth factor NDP (NDP) mutations in a cohort of Indian patients with FEVR by whole-exome sequencing. Methods: We performed data filtering and bioinformatic analyses. Results: Two novel heterozygous mutations in FZD4 gene were identified, each in two different families: c.1499_1500del [p.500_500del] and c.G296C [p.C99S]. One novel mutation in NDP in another family was identified: c.A256G [p.K86E]. All FZD4 mutations affected conserved amino acid residues and were absent in 1000 control individuals. To assess the effect of these FZD4 mutations on the biological activity of the protein, we introduced each FZD4 mutation into FZD4 cDNA by the site-directed mutagenesis techniques. A Norrin/beta-catenin pathway-based luciferase reporter assay revealed that the c.1499_1500del failed to activate the luciferase reporter; in contrast, compared with the wild-type FZD4 protein, the, c.G296C [p.C99S] mutation exhibited increased luciferase reporter activity. Conclusion: Our study found two novel FZD4 mutations, with opposite effects regarding functional expression levels in Indian patients with FEVR and expands on the mutational spectrum of FZD4 in Indian FEVR patients.

Abstract
Objective: To explore the death risk factors of extremely severe burn patients, establish a death risk nomogram predicting model, and investigate the predictive value for death risk of extremely severe burn patients. Methods: The medical records of 231 extremely severe burn patients (190 males and 41 females, aged 18-60 years) who were admitted to the Institute of Burn Research of the First Affiliated Hospital of Army Medical University from January 2010 to October 2018 and met the inclusion criteria were analyzed retrospectively. According to the final outcome, the patients were divided into survival group of 173 patients and death group of 58 patients. The sex, age, severity of inhalation injury, total burn area, full-thickness burn area, burn index, rehydration coefficient and urine volume coefficient of the first and second 24 h after injury, the first base excess, shock index, and hematocrit (HCT) after admission, whether to have pre-hospital fluid infusion, use of ventilator, and use of continuous renal replacement therapy (CRRT), and abbreviated burn severity index (ABSI ) and Baux score on admission of patients in the two groups were recorded or calculated. According to the use of ventilator, the patients were divided into with ventilator group of 131 patients and without ventilator group of 100 patients, and the death, total burn surface area, burn index, incidence and severity of inhalation injury were recorded. According to the use of CRRT, the patients were divided into with CRRT group of 59 patients and without CRRT group of 172 patients, and the death, total burn surface area, and burn index were recorded. Data were statistically analyzed with t test, chi-square test, and Mann-Whitney U test to screen the death related factors of patients. The indexes with statistically significant differences between survival group and death group were included in the multivariate logistic regression analysis to screen the independent death risk factors of patients, and the death risk nomogram predicting model was constructed based on the results.The Bootstrap method was used to validate the death risk nomogram predicting model internally. The predictive value of the nomogram model for predicting death risk of patients was detected by drawing calibration graph and calculating concordance index, and the death risk scores of 231 patients were acquired according to the death risk nomogram model. The receiver's operating characteristic (ROC) curve was drawn, and the optimal threshold and the sensitivity and specificity of optimal threshold in the ROC curve and the area under the curve were calculated. Results: (1) There were statistically significant differences in burn index, ABSI on admission, severity of inhalation injury, total burn area, full-thickness burn area, rehydration coefficient at the first 24 h after injury, use of ventilator, use of CRRT, and Baux score on admission of patients between the two groups (Z=-7.696, -7.031, χ(2)=18.304, 63.065, 23.300, 13.073, 34.240, 59.586, t=-7.536, P<0.01). (2) There were statistically significant differences in death, incidence and severity of inhalation injury, total burn area, and burn index of patients between with ventilator group and without ventilator group (χ(2)=34.240, 17.394, 25.479, Z=-6.557, -7.049, P<0.01). (3) There were statistically significant differences in death, total burn area, and burn index of patients between with CRRT group and without CRRT group (χ(2)=62.982, Z= -47.421, -6.678, P<0.01). (4) The use of ventilator, use of CRRT, and burn index were independent risk factors for the death of extremely severe burn patients (odds ratio=3.277, 5.587, 1.067, 95% confidence interval=1.073-10.008, 2.384-13.093, 1.038-1.096, P<0.05 or P<0.01). (5) The initial concordance index of nomogram predicting model was 0.90 and the corrected concordance index was 0.89. The concordance indexes before and after correction were higher and similar, which showed that the nomogram had good concordance and predictive effect. The optimum threshold of ROC curve was 0.23, the sensitivity and specificity of optimum threshold were 86.0% and 80.0%, respectively, and the area under ROC curve was 0.90 (95% confidence interval=0.86-0.94, P<0.01). Conclusions: Severe burns and damage and/or failure of organ are the main death causes of extremely severe burn patients. The death risk nomogram predicting model established on the basis of use of ventilator, use of CRRT, and burn index have good predictive ability for death of extremely severe burn patients.

Abstract
Gold nanoparticles (AuNPs) have attracted considerable interest in suppressing tumor cell migration, while small extracellular vesicles (sEVs) play an essential role in tumor metastasis by shaping the tumor microenvironment. Understanding how AuNPs alter sEV attributes is critical in antitumor medication design. In this study, mouse embryonic stem cells (mESCs) were treated with three sizes of AuNPs (i.e. 5 nm AuNPs, 20 nm AuNPs, and 80 nm AuNPs) to obtain sEVs (i.e. sEV-5, sEV-20, and sEV-80), which were characterized from the biophysical and proteomic aspects. When compared with the control (sEV-ctrl), sEV-5 possessed relatively higher rigidity, and a differentially expressed protein profile. It attenuated 4T1 tumor cell proliferation and migration through inhibiting cofilin expression and extracellular regulated protein kinase (Erk) phosphorylation, which was opposite to the effect induced by sEV-ctrl. In contrast, sEV-20 and sEV-80 had negligible effects. This study revealed for the first time that AuNP-5 exposure changed the biophysical properties and cellular functions of mESC-derived sEVs, providing a promising strategy for designing AuNP-based antitumor medication.

Abstract
Individuals with substance use disorders (SUD) undergo treatment to recover from addiction. However, exerting self-control, which is essential for successful abstinence from drug addiction, can cause ego depletion. This study experimentally investigated the effect of ego depletion on interpersonal trust and examined possible changes in the ego depletion effect across different abstinence periods. This study employed a 2 (ego depletion: high vs. low) × 2 (partners: non-SUD vs. SUD) mixed factorial design. The participants were 273 male individuals with SUD and with periods of drug abstinence ranging from several days to 2 years, who resided in a compulsory drug rehabilitation center. The participants were first asked to complete an ego depletion task, followed by a decision-making task in a trust game, first with a non-SUD stranger, and then with a SUD stranger. Ego depletion was not related to trust in non-SUD strangers. However, ego depleted participants were more likely to trust SUD strangers than non-ego depleted participants. Moreover, this ego depletion effect fluctuated near the end of SUD treatment. This study highlights the importance to ensure follow-up outpatient care and offer social support services for individuals with SUD after compulsory SUD treatment.

Abstract
Understanding the structure-reactivity relationship at the atomic scale is of great theoretical importance for rational design of highly active catalysts, which has long been a central concern in catalysis communities and interface science. Herein, we developed a high-efficiency catalyst for catalytic oxidation of C6H12 by poststructural decoration on well-defined single-crystal facets of hematite. Especially for Cl-decorated {012} facets, the conversion and KA oil selectivity are improved about 3.4 times and 2 times, respectively. A better catalytic performance of the newly formed active site is derived from the charge difference between Cl and the neighboring outmost O atoms, which is affected by the geometric and electronic structures of the original catalyst surface. Based on the experimental results and the theoretical analysis, we concluded that the contribution of various O terminations to Cl-decoration follows the order O(I) > O(III) > O(II). Cl-decorated {001} facets show the highest intrinsic activity, whereas Cl-decorated {012} facets show the best catalytic performance because of their more active sites for Cl-decoration.

Abstract
BACKGROUND We sought to explore the effects of sodium valproate combined with lamotrigine on quality of life and serum inflammatory factors in patients with poststroke secondary epilepsy. METHODS A total of 145 patients with post-stroke secondary epilepsy admitted to our hospital from January 2017 to June 2018 were collected: 76 treated with sodium valproate combined with lamotrigine (study group) and 69 patients treated with sodium valproate alone (control group). The levels of serum high-mobility group protein B1, matrix metalloproteinase 9, and interleukin 6 were detected before and after treatment, and the therapeutic efficacy and adverse reactions were compared between the 2 groups. RESULTS The total effective rate of the study group was higher than that of the control group. Both groups decreased in epileptiform discharges or in the number of involved leads after treatment, with the results of the study group being lower than those of the control group. The quality of life scores in both groups was increased after treatment, albeit the scores of the study group were higher than those of the control group. In terms of the levels of serum inflammatory factors, the 2 groups were reduced after treatment; the levels of the study group were lower than those of the control group. Regarding the incidence of adverse reactions, no significant difference was seen between the 2 groups. CONCLUSIONS Sodium valproate combined with lamotrigine has better clinical efficacy and higher safety in the treatment of poststroke secondary epilepsy and is able to reduce the expression levels of serum inflammatory factors.
