Abstract
Sialic acids are a family of monosaccharides that share a nine-carbon backbone and a carboxyl group. A recent derivatization method based on 3-nitrophenylhydrazine (3-NPH) provides a mild chemical labeling technique for biomolecules containing carbonyl or carboxyl groups. In this study, we utilized 3-NPH to label sialic acids via a two-step derivatization process. The derivatized species can produce a common reporter ion corresponding to C1-C3 with two labels, and a fragment differentiating between Neu5Ac, Neu5Gc, and KDN. This method is compatible with O-acetylated sialic acids and provides high sensitivity to Neu5Gc and KDN, and since the utilization of dual labeling significantly enhances the hydrophobicity of derivatives, it can effectively mitigate matrix effects when combined with parallel reaction monitoring technology. Negative-ion tandem mass spectrometry (MS/MS) analysis reveals a distinctive fragmentation profile for the 4-O-acetylated species, while the other sialic acids yield similar MS/MS spectra with a high abundance of reporter ions. Using the reporter ion as a transition, this analytical strategy is effective for analyzing complex biological samples. For example, it was successfully employed to quantify sialic acids in the intestinal tissues of several carp species, demonstrating its potential in sialylation research.

Abstract
Staphylococcus aureus (S. aureus) has the ability to invade human cortical bones and cause intracellular infections in osteoblasts, which may lead to a long-term infection that is difficult to eliminate. It is critical to identify the underlying mechanisms of the osteoblast response to the intracellular S. aureus. More recently, multiple circular RNA (circRNA) functions have been identified, including serving as protein scaffolds or miRNA sponges and being translated into polypeptides. The role that circRNAs play in intracellular S. aureus infection of osteoblasts has not, to our knowledge, been investigated. Here, we established an intracellular infection model of S. aureus in osteoblasts and compared the circRNA expression of osteoblasts between the infected and control groups using RNA sequencing technology, by which a significant difference was found. In total, 117 upregulated and 125 down-regulated differentially expressed circRNAs (DEcircRNAs) were identified, and reverse transcription-quantitative PCR was employed to validate the results of RNA sequencing. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses demonstrated that DEcircRNAs were enriched in processes associated with macromolecule modification, cellular component organization or biogenesis, and intracellular non-membrane-bound organelles. Finally, a potentially important network of circRNA-miRNA-mRNA based on the DEcircRNAs was constructed. Overall, this study revealed the circRNA expression profile of human osteoblasts infected by intracellular S. aureus for the first time, and identified the circRNAs that may contribute to the pathogenesis of infectious diseases caused by intracellular S. aureus infection in human osteoblasts.

Abstract
The oceanic-to-neritic species shift of microzooplanktonic tintinnids and their interaction with relevant abiotic variables are two crucial processes in the marine ecosystem. However, these processes remain poorly documented in China's marginal seas. In the summer of 2022, we investigated the community structure of pelagic tintinnids in surface waters from the South China Sea (SCS) to the Yellow Sea (YS), passing through the East China Sea (ECS). A number of 58 species from 23 genera were identified, with 36 and 22 species belonging to oceanic and neritic genera, respectively. The abundance proportion of oceanic and neritic genera exhibited a decreasing and increasing trend, respectively, from the SCS to YS. Furthermore, four distinctive tintinnid community groups were classified based on cluster analysis using tintinnid species and abundance data, and the position of southern Taiwan Strait was identified as the "Shift Point" for oceanic-to-neritic species dominance. The top two tintinnid species in each group showed distinct variations in body size. Additionally, multivariate biotic-abiotic statistical analyses revealed that temperature determined tintinnid species richness, while temperature, salinity, Si(OH)4, and Chl a determined tintinnid abundance. Our study provides a substantial foundation for recognizing the oceanic-to-neritic species shift of tintinnids in the China's marginal seas, and highlights the role of biotic-abiotic factors in driving biogeochemical fluxes and the potential response of microzooplankton to future climate change.

Abstract
The tremendous loss of microplastics from the sea surface and the low density of microplastics found in the water column and sediments indicate that the oceans have mechanisms capable of transporting microplastics from the surface to the seafloor. These include physicochemical processes and biological influences from marine organisms that drive the vertical migration of microplastics. Little is known, however, about the biological processes involved in the deposition of plastics in the marine environment. A considerable number of mariculture filter-feeding organisms can consume substantial amounts of suspended substances in the water column, and these organisms are ideal candidates for depositing microplastics. In this study, we analyzed microplastic abundance in typical mariculture filter feeders, i.e., ascidians (Halocynthia roretzi), oysters (Crassostrea gigas), scallops (Chlamys farreri) and clams (Ruditapes philippinarum), quantified the number and characteristics of the microplastics they deposited in situ, and further compared microplastic biodeposition rates. Microplastics were present in feces and pseudofeces and sank to form biodeposits rather than accumulating to significant levels in organisms. Microplastics were found in significantly higher numbers in the biodeposits of mariculture organisms than in the control deposits (p < 0.01). The shape and color of the microplastics in the sediments were not impacted by the presence of organisms (p > 0.05), but the deposition of <1000 μm and positive-buoyancy (less dense than seawater) microplastics was significantly increased in the biodeposits (p < 0.05). The highest microplastic biodeposition rate was found in scallops (1.14 ± 0.07 items·ind-1·d-1 or 0.5 ± 0.03 items·g-1·d-1). These results suggest that mariculture filter-feeding organisms have important biodepositional functions that influence the fate of microplastics through the transfer of microplastics from the surface to the seafloor. This study could contribute to a better understanding of the biological plastic pump mechanisms in oceans.

Abstract
High-throughput metabolomics data provide a detailed molecular window into biological processes. We consider the problem of assessing how the association of metabolite levels with individual (sample) characteristics such as sex or treatment may depend on metabolite characteristics such as pathway. Typically this is one in a two-step process: In the first step we assess the association of each metabolite with individual characteristics. In the second step an enrichment analysis is performed by metabolite characteristics among significant associations. We combine the two steps using a bilinear model based on the matrix linear model (MLM) framework we have previously developed for high-throughput genetic screens. Our framework can estimate relationships in metabolites sharing known characteristics, whether categorical (such as type of lipid or pathway) or numerical (such as number of double bonds in triglycerides). We demonstrate how MLM offers flexibility and interpretability by applying our method to three metabolomic studies. We show that our approach can separate the contribution of the overlapping triglycerides characteristics, such as the number of double bonds and the number of carbon atoms. The proposed method have been implemented in the open-source Julia package, MatrixLM. Data analysis scripts with example data analyses are also available.

Abstract
Additive manufacturing (AM) is a burgeoning technology for fabricating complex components with high efficiency and low material waste. However, the surface of AM parts is rough owing to partially melted powders and severe surface fluctuation. Electrochemical machining (ECM) is a suitable postprocessing method to finish the surface of the AM parts, and the low current density is usually employed. Our study illustrates the electrochemical dissolution characteristics of the horizontal and vertical sections of the AM SUS 304 component under a low current density and the electrochemical finishing process to obtain smooth surfaces. Linear and fan-shaped melt pools are observed on the horizontal and vertical sections, respectively. Moreover, the melt pool boundaries are vulnerable to dissolution and separate the hollows, basins, and swellings formed after electrochemical dissolution. The two sections display similar current efficiency and polarization because of the single austenitic phase and the identical and uniform elemental content distribution. The top and side surfaces of the AM sample could be efficiently smoothened via ECM by eliminating the partially melted powders and significantly reducing the surface roughness. The numerous band humps make the top surface of the AM sample difficult to smoothen compared with the side surface under the point effect of the electric field.

Abstract
Atmospheric microplastics are attracting increasing attention as an emerging pollutant. However, research on its characteristics and influencing factors is insufficient. This study examines the characteristics and spatiotemporal distribution of atmospheric microplastics around Jiaozhou Bay, the Yellow Sea. The results showed that the dominant shapes of microplastic were fragments (61.9 %) and fibers (25.6 %), and the main types were polyethylene terephthalate (23.8 %), polyethylene (31.6 %) and cellulose (rayon, 34.9 %). The deposition rate of microplastic varied from 8.395 to 80.114 items·m-2·d-1, with a mean of 46.708 ± 21.316 items·m-2·d-1. The deposition rate was higher in the dry season than in the rainy season, indicating the influence of weather condition. The annual mass of atmospheric microplastics entering the bay was estimated to be 7.612 ± 3.474 tons. For the first time, this study reveals that atmospheric microplastics in Jiaozhou Bay change spatiotemporally due to monsoons, which pose a potential threat to marine ecosystems.

Abstract
Dental caries is a dynamic disease induced by the unbalance between demineralization of dental hard tissues caused by biofilm and remineralization of them; however, although various effective remineralization methods have been well documented, it is a challenge to reestablish the balance by enhancing remineralization alone while ignoring the antibacterial therapy. Therefore, the integration of remineralizing and antibacterial technologies offers a promising strategy to halt natural caries progression in clinical practice. Here, the conception of interrupting dental caries (IDC) was proposed based on the development of dual-functional coating with remineralizing and antibacterial properties. In this study, bovine serum albumin (BSA) loaded octenidine (OCT) successfully to form a BSA-OCT composite. Subsequently, through fast amyloid-like aggregation, the phase-transited BSA-OCT (PTB-OCT) coating can be covered on teeth, resin composite, or sealant surfaces in 30 min by a simple smearing process. The PTB-OCT coating showed satisfactory effects in promoting the remineralization of demineralized enamel and dentin in vitro. Moreover, this coating also exerted significant acid-resistance stability and anti-biofilm properties. Equally importantly, this coating exhibited promising abilities in reducing the microleakage between the tooth and resin composite in vitro and preventing primary and secondary caries in vivo. In conclusion, this novel dual-functional PTB-OCT coating could reestablish the balance between demineralization and remineralization in the process of caries, thereby potentially preventing or arresting caries.

Abstract
Bacteria frequently interfere with the post-translational modifications of host cells to facilitate their survival and growth after invasion. SUMOylation, a reversible post-translational modification process, plays an important role in biological life activities. In addition to being critical to host cell metabolism and survival, SUMOylation also regulates gene expression and cell signal transmission. Moreover, SUMOylation in eukaryotic cells can be used by a variety of bacterial pathogens to advance bacterial invasion. In this minireview, we focused on the role and mechanism of host SUMOylation in the pathogenesis of six important clinical bacterial pathogens (Listeria monocytogenes, Shigella flexneri, Salmonella Typhimurium, Klebsiella pneumoniae, Staphylococcus aureus, and Escherichia coli). Taken together, this review provided new insights for understanding the unique pathogen-host interaction based on host SUMOylation and provided a novel perspective on the development of new strategies to combat bacterial infections in the future.

Abstract
In recent years, research on tetracycline antibiotics has gradually shifted from their antibacterial effects to anticancer effects. Doxycycline, minocycline, and tigecycline as the US Food and Drug Administration (FDA) approved tetracycline antibiotics have been the main subjects of studies. Evidence indicated that they have anticancer properties and are able to control cancer progression through different mechanisms, such as anti-proliferation, anti-metastasis, and promotion of autophagy or apoptosis. In addition, studies have shown that these three tetracycline antibiotics can be utilized in conjunction with chemotherapeutic and targeted drugs to inhibit cancer progression and improve the quality of patient survival. Therefore, doxycycline, minocycline, and tigecycline are taken as examples in this work. Their mechanisms of action in different cancers and related combination therapies are introduced. Their current roles in alleviating the suffering of patients undergoing chemotherapy when used as adjuvant drugs in clinical treatment are also described. Finally, the research gaps and potential research directions at this stage are briefly summarized.

Abstract
PURPOSE/OBJECTIVE(S) CAPSTONE-1, a phase 3 trial, showed that SHR-1316 (PD-L1 antibody) combined with standard first-line chemotherapy could prolong overall survival (OS) in patients (pts) with ES-SCLC. The CREST trial reported consolidative thoracic radiotherapy (TRT) of 30 Gy in 10 fractions provided a 10% 2-year OS benefit and more intensive TRT should be investigated in ES-SCLC. In the era of immunotherapy, the role of TRT also needs further exploration. Therefore, we designed this clinical trial to investigate the efficacy and safety of SHR-1316 plus first-line chemotherapy followed by TRT combined with SHR-1316. MATERIALS/METHODS Key inclusion criteria were pts aged 18-75 years, with previously untreated histologically or cytologically confirmed ES-SCLC, and an ECOG performance status of 0-1. Eligible pts would receive 4∼6 cycles of SHR-1316 (20mg/kg, D1, q3w) combined with EP/EC (etoposide, 100mg/m2, D1-5, q3w and cisplatin, 75mg/m², D1-3, q3w or carboplatin, AUC = 5, D1, q3w), followed by SHR-1316 combined with TRT (≥3 Gy*10 f or ≥2 Gy*25 f, involved-field irradiation), and then the maintenance therapy with SHR-1316 until disease progression or intolerable adverse events (AEs). The main endpoints included ORR, PFS and safety. RESULTS From October 2020 to January 2023, 33 pts received SHR-1316 and sequential consolidative TRT. Among them, 19 pts received high-dose TRT (>3 Gy*10 f or ≥2 Gy*25 f) and 14 pts received low-dose TRT (≤3 Gy*10 f or<2 Gy*25 f). The median age was 62 (range: 38-73). Most pts were male (28, 84.8%), former smokers (22, 66.7%) with an ECOG performance status 1 (32, 97%). Ten (30.3%) pts were diagnosed with brain metastasis and 10 (30.3%) pts had liver metastasis at baseline. At the data cutoff date, 9 pts remained on treatment, the average number of treatment cycles was 9.2. 33 pts had at least one 1 post-treatment tumor assessment. The confirmed ORR and DCR were 90.9% (30/33) and 100% (33/33) in all pts, were 89.5% (17/19) and 100% (19/19) in high-dose TRT group, and were 92.9% (13/14) and 100% (14/14) in low-dose TRT group. The median PFS was 10.2(CI: 5.8∼14.7) months in all pts, was 7 (CI: 3.8∼10.2) months in high-dose TRT group and 10.4 (CI: 8.4∼12.3) months in low-dose TRT group. AEs occurred in 27 (81.8%) pts and grade 3 or 4 AEs occurred in 20 (60.6%) pts. The most common grade 3 or 4 AEs included neutropenia (15, 45.5%), leukopenia (8, 24.2%), lymphocytopenia (5, 15.2%), pneumonia (3, 9.1%), anemia (3, 9.1%) and thrombocytopenia (2, 6.1%). CONCLUSION SHR-1316 plus chemotherapy and sequential TRT as first-line therapy for ES-SCLC showed promising efficacy and acceptable safety. There is no significant difference between high-dose and low-dose TRT groups in terms of safety and efficacy according to current data.

Abstract
PURPOSE/OBJECTIVE(S) MRI-based synthetic CT (SCT) images created using generative adversarial network (GAN) have been demonstrated to be feasible for intensity-modulated proton therapy (IMPT) planning. However, dose calculation accuracy can be uncertain in some regions within/near the target of head and neck patients due to the local CT number estimation error or sharp dose fall-off. This study investigated the feasibility of using the SPArc technique to mitigate such dosimetric uncertainty. MATERIALS/METHODS A GAN using a 3D U-net as the generator and a 6-layer 3D convolutional neural network as the discriminator was trained with T1-weighted MR-CT image pairs from 162 nasopharyngeal carcinoma patients (14 for validation). The generator was used to generate SCT images from MR images for 7 test patients. For each test patient, the CT image was used to create a SPArc plan and an IMPT plan with the same clinical objectives. The SPArc plans (control point frequency sampling, arc trajectory, etc.) were optimized using a previously developed iterative approach. The dose distributions of both SPArc plans and IMPT plans were re-calculated on the SCT images and compared to the one calculated on the CT images. The dosimetric uncertainty was quantified using the gamma index. RESULTS The 2%/2mm and 3%/3mm passing rates for SPArc plans were (96.9¡À2.7) % and (98.6¡À1.5) %, while the passing rates for IMPT plans were (94.0¡À3.9) % and (96.4+2.9) %. A significant reduction in dosimetric uncertainty was identified for SPArc plans (p ¡Ü0.021). Table 1 shows the passing rates for the 7 test individuals. CONCLUSION SPArc can mitigate the uncertainty of dose calculation in MRI-based proton planning. Further research needs to validate these findings on a larger patient cohort. The study paves the road map for using MRI for SPArc planning.

Abstract
Crohn's disease (CD) is an inflammatory bowel disease that is characterized by chronic inflammation of digestive system and has a nickname "green cancer" because of its sustained alternation of periods of flares and remissions. Here, we investigated the inflammation changes in peripheral blood system of CD patients, which are less reported in China. Peripheral blood samples of 167 CD patients and 30 healthy people, as well as their clinical information, were collected at the Second Affiliated Hospital of Soochow University. Flow cytometry was performed to analyze the ratio of CD4 T cells to CD8 T cells. Cytometric Bead Array kit was used to detect the cytokines in peripheral blood in CD patients. Moreover, the expression of inflammasomes was also detected by RT-PCR. The percentage and cell number of lymphocytes in CD patients' peripheral blood system decreased significantly, while monocytes increased remarkably. Interestingly, there was an inversion of the CD4 T cells/CD8 T cells ratio in peripheral blood of CD patients. The levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) increased significantly in CD patients' peripheral blood, and lipopolysaccharide (LPS) stimulation aggravate inflammatory response. In addition, the expression of nucleotide-binding oligomerization domain-like receptor family, pyrin domain-containing 1 (NLRP1) and NLRP3 in peripheral blood mononuclear cells (PBMC) of CD patients increased significantly after LPS stimulation. The inflammation in peripheral blood of CD patients had significant changes, including PBMC, cytokines and inflammasomes. These results are helpful to get a deeper understanding of CD and improve the efficiency of diagnosis and treatment in China.

Abstract
Fungi have essential functions in plant health and performance. However, the plant-associated functions of many cultured fungi have not been established in detail. Here, the fungal species diversity in Salvia miltiorrhiza roots and rhizosphere was assessed for the first time using culturomics and high-throughput sequencing. We present a comprehensive functional metagenomic analysis of these fungi and verified activity of cellulase and chitinase predicted in the metagenomic analysis. We first collected and cultured fungi from the root and rhizosphere of S. miltiorrhiza. We found 92 species across 37 families and five phyla, with Ascomycota being dominant. Many rDNA internal transcribed spacer sequences could not be assigned to lower taxonomic levels. There were 19 genera of endophytic fungi and 37 genera of rhizosphere fungi. The culturomics approach had lower taxonomic diversity than high-throughput sequencing, but some fungi were only found in cultures. Structural analyses indicated that the dominant species differed in cultured and non-cultured samples at other levels, apart from the phylum level. Functional analysis mapped 223 carbohydrate enzyme families and 393 pathways in the CAZy and KEGG databases, respectively. The most abundant families were glycoside hydrolases and those involved in carbohydrate metabolism. As predicted by metagenomics, we experimentally verified cellulase and chitinase activity for 29 and 74 fungi, respectively. We provide the first evidence of biomass recycling by fungi that are associated with plants. Culturing is essential to reveal the hidden microbial community and critical functions in plant-microbe interactions.

Abstract
PURPOSE/OBJECTIVE(S) Persistent infection of human papillomavirus (HPV) is one major etiology of cervical cancer (CC). By now, anti-PD-1 immunotherapy is approved for advanced CC patients, but the response rate was just about 10-20%, tumor immune microenvironment (TIME) might be one factor that affect the efficacy. The indoleamine 2,3-dioxygenase (IDO), a metabolic immune checkpoint, is recently shown to have a correlation-ship with HPV carcinogenesis in CC, with unknown mechanism. This study, using the single cell transcriptomic single-cell sequencing and spatial transcription sequencing analysis/immunologic technology, aimed to exam the role of IDO1 expression in HPV+ CC TIME and explore the changes after radiotherapy. MATERIALS/METHODS Newly diagnosed advanced HPV- CC and HPV+ CC patients were tested for the tumor and tumor immune microenvironment (TIME) heterogeneity and their changes after fractionated radiation therapy. Tumor tissues were collected, single cell suspension was made for Single-cell RNA sequencing (SCRNAseq) using the 10 × Genomics, while frozen tissue was embedded for spatial transcriptome sequencing (STRNAseq). Seurat 4.0 was used to cluster and annotate cell clusters and map SCRNAseq data to the STRNAseq data. The specific characters of cell clusters were computed by Gene Set Enrichment Analysis (GSEA). SPOTLight and CellChat were used to analyze cell location and interaction respectively. RESULTS A total of 28631 cells were clustered into 31 cell subsets in HPV- CC and HPV+ CC tissues, including baseline (Pre HPV- CC and Pre HPV+ CC) and 3-week after radiotherapy (Post 3w HPV- CC and Post 3w HPV+CC). There were 10431 epithelial cells (Epi) in all these 4 tumor tissues, with heterogenous IDO1 expression, including IDO1-high Epi, IDO1-low Epi, and IDO1-neg Epi. Interestingly, more than 99% of Epi in Pre HPV- CC tissues were IDO1-neg cells, while more than 99% in Pre HPV+ CC tissue were IDO1-high. Furthermore, the proportion of IDO1-high Epi in Pre HPV+ CC patient dropped to 16.7% after radiotherapy, while the proportion of IDO1-low Epi rase to 63.3%. Using GSEA, the characters of IDO1-high Epi group was shown to have positive regulation of leukocyte chemotaxis and negative regulation of cell adhesion and differentiation. IDO1-high Epi cells also had the hallmark of interferon gamma response. These cells could mainly receive regulative information of interferon gamma pathway from exhausted CD8 T cells, which could affect the apoptosis of tumor cells. CONCLUSION This study comprehensively analyzed the immune suppressive role of IDO1-high Epi cells in HPV+ CC TIME at the single-cell transcriptional scale and explored their functional characters in CC radiotherapy. This would be able to provide more evidence to combine with radiotherapy and immunotherapy to improve patients' prognosis.

Abstract
PURPOSE/OBJECTIVE(S) Re-radiotherapy (re-RT) is the main treatment for locally recurrent nasopharyngeal carcinoma (lrNPC) patients, and commonly led to radiation-induced nasopharyngeal (NP) necrosis, which was lethal but rare study has focused on it. The aim of this study was to evaluate the cause and impact of radiation-induced NP necrosis in lrNPC patients who received re-RT. MATERIALS/METHODS Totally 252 lrNPC patients who received re-RT between January 2013 and December 2020 were retrospectively collected. The inclusion criteria were as follows: (1) no NP necrosis before re-RT; (2) complete medical records, including treatment, clinical and dosimetric information; (3) conventional fractionated radiotherapy. All patients received intensity-modulated radiotherapy ± chemotherapy. Radiation-induced NP necrosis was diagnosed by magnetic resonance imaging and/or electronic nasopharyngoscopy. Dosimetric factors of the planning target volume of primary tumor (PTVp) were extracted from the dose-volume histogram (DVH), which was rescaled to an equivalent dose of 2 Gy per fraction (EQD 2 Gy) using a linear quadratic model. Logistic regression was used to identify the independent prognostic factors for generating the nomogram. RESULTS With a median follow-up of 44.63 months (inter-quartile range [IQR], 27.70 - 69.20 months), 47.6% of patients (120/252) occurred radiation-induced NP necrosis, which mostly happened within 1 year post re-RT (median [IQR], 5.83 [3.37 - 11.57] months). The 3-year overall survival was 83.0% vs 39.7% (P<0.001) in lrNPC patients with or without radiation-induced NP necrosis. Except for the fractionated dose, other dosimetric factors of PTVp were not significantly different between two groups, including D98 (dose to 98% of PTVp), D50, D2 and homogeneity index (Table 1). Furthermore, multivariate analysis showed that continuous variable age (HR [95% CI]: 1.04 [1.02 - 1.07], P = 0.003) and tumor volume (HR [95% CI]: 1.02 [1.01 - 1.03], P<0.001), and fractionated dose > 2.22 Gy (HR [95% CI]: 2.36 [1.32 - 4.21], P = 0.004) were independent factors in predicting radiation-induced NP necrosis, which yielded a C-index of 0.742 (95% CI, 0.682 - 0.803) for OS in the nomogram. CONCLUSION The incidence of radiation-induced NP necrosis was high in lrNPC patients who received re-RT. Patients with older age, larger tumor volume or receiving fractionated dose over 2.22 Gy were more easily to suffer NP necrosis, which need to explore novel treatment strategies to improve patients' survivals.

Abstract
Staphylococcus haemolyticus (S. haemolyticus) is a coagulase-negative Staphylococcus that has become one of the primary causes of nosocomial infection. After a long period of antibiotic use, S. haemolyticus has developed multiple resistance phenotypes for macrolides and lincosamides. Herein, we evaluated four S. haemolyticus clinical isolates, of which three had antibiotic resistance patterns reported previously. The fourth isolate was resistant to both erythromycin and clindamycin in the absence of erythromycin induction. This novel phenotype, known as constitutive macrolides-lincosamides-streptogramins resistance, has been reported in other bacteria but has not been previously reported in S. haemolyticus. Investigation of the isolate demonstrated a deletion in the methyltransferase gene ermC, upstream leader peptide. This deletion resulted in constitutive MLS resistance based on whole-genome sequencing and experimental verification. Continuous expression of ermC was shown to inhibit the growth of S. haemolyticus, which turned out to be the fitness cost with no MLS pressure. In summary, this study is the first to report constitutive MLS resistance in S. haemolyticus, which provides a better understanding of MLS resistance in clinical medicine. IMPORTANCE This study identified a novel phenotype of macrolides/lincosamides resistance in Staphylococcus haemolyticus which improved a better guidance for clinical treatment. It also clarified the mechanistic basis for this form of antibiotic resistance that supplemented the drug resistance mechanism of Staphylococcus. In addition, this study elaborated on a possibility that continuous expression of some resistance genes was shown to inhibit the growth of bacteria themselves, which turned out to be the fitness cost in the absence of antibiotic pressure.

Abstract
Objective: To analyze the long-term quality of life of patients with Brown Ⅱ maxillary defect repaired by tissue flap or prosthesis. Methods: Patients who underwent surgery for maxillary malignant tumors in the First Affiliated Hospital of Bengbu Medical College from 2014 to 2017 were selected to investigate the postoperative long-term (>5 years) quality of life using the fourth edition of the University of Washington quality of life questionnaire (UW-QOL). Mann Whitney U test was used to examine the differences between two groups. Results: In this study, 4 cases were lost to follow-up, 9 died, and a total of 46 valid questionnaires were collected, including 24 males and 22 females, aged 19-86 years. There were 26 cases of class Ⅱb/c and 20 cases of class Ⅱd. Tissue flap reconstruction was performed in 29 cases (tissue flap group) and prosthesis restoration in 17 cases (prosthesis group). The score of chewing QOL in the prosthesis group was higher than that in the tissue flap reconstruction group (Z=-2.787, P=0.005), but the scores of entertainment, swallowing, speech and emotion QOL in the former group were respectively lower than those in the latter group (Z=-3.185, -2.091, -2.556 and -1.996, respectively, all P values<0.05). In patients with Brown Ⅱb/c defect, the prosthesis repair could improve the chewing QOL score (Z=-2.830, P=0.005), but no statistically significant differences in other QOL scores between two groups. In patients with Brown Ⅱd defect, the tissue flap reconstruction could improve the scores of pain, entertainment, swallowing and speech QOL (Z=-2.741, -2.517, -2.320 and -2.843, respectively, all P values<0.05), and the average QOL score in tissue flap reconstruction group was also higher than that of the prosthesis group (Z=-2.276, P=0.023). Conclusion: For postoperative long-term quality of life, both prosthesis and tissue flap reconstruction can offer satisfactory results in patients with Brown Ⅱb/c defect, and patients with Brown Ⅱd defect repaired by tissue flap reconstruction have better speech and swallowing functions. Tissue flap reconstruction may bring more entertainment and emotional benefits.

Abstract
Objective: To investigate the clinical characteristics of patients with rheumatic diseases and abnormal liver function, as well as determine the proportion and severity of liver function abnormalities. Methods: Cross-sectional study. Data were collected from patients registered in the Chinese Rheumatism Date Center from 2011 to 2021. The rheumatic diseases analyzed in this study were rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjogren syndrome (SS), ankylosing spondylitis (AS), and gout. Patient data, including demographic characteristics [ such as age, sex, body mass index,(BMI), and smoking history], liver function test results [including alanine aminotransferase (ALT), aspartate aminotransferase, alkaline phosphatase(ALP), and total bilirubin], and use of anti-rheumatic immune drugs and liver-protective drugs, were collected and compared between groups with normal and abnormal liver functions. In addition, the proportions of abnormal liver function were compared between sex and age groups. Results: A total of 116 308 patients were included in this study, including 49 659 with RA, 17 597 with SLE, 9 039 with SS, 11 321 with AS, and 28 692 with gout. The lowest proportion of liver function abnormalities was observed in patients with RA[11.02% (5 470/49 659)], followed by those with SS[17.97% (1 624/9 039)] and AS [18.22% (2 063/11 321) ], whereas patients with SLE [21.14% (3 720/17 597) ] and gout [28.73% (8 242/28 692)] exhibited the highest proportion of these abnormalities. Elevated ALT, mostly classified as grade 1, was the most commonly noted liver function abnormality, whereas elevated ALP was the least common. Some patients who took liver-protective drugs had normal liver function, with the lowest percentage observed in patients with gout [7.45% (36/483) ] and ranging from 21.7% to 30.34% in patients with RA, SLE, SS, and AS. The proportion of liver function abnormalities was higher in males than in females for all disease types [RA: 13.8%(1 368/9 906) vs. 10.3%(4 102/39 753); SLE: 33.6% (479/1 424) vs. 20.0% (3 241/16 173); SS: 25.4%(111/437) vs. 17.6%(1 513/8 602); AS: 20.1%(1 629/8 119) vs. 13.6% (434/3 202); and gout: 29.3% (8 033/27 394) vs. 16.1% (209/1 298)]. In RA, SLE, and AS, the proportions of liver function abnormalities were similar across all age groups. In SS, the proportion of liver function abnormalities increased with age [<40 years: 14.9%(294/1 979); 40-59 years: 18.1%(858/4 741); ≥60 years: 20.4%(472/2 319)], whereas a reversal of this trend was observed in gout [<40 years: 34.9%(4 294/12 320); 40-59 years: 25.5%(2 905/11 398);≥60 years: 21.0%(1 042/4 971)]. Conclusions: The proportions of combined liver function abnormalities in patients with rheumatologic diseases were high, and the utilization rates of liver-protective drugs were low. It is necessary to pay more attention to monitoring patients' liver function, timely administer liver-protective drugs, and optimize liver-protective regimens during the treatment of rheumatic diseases.

Abstract
Visual positioning is a basic component for UAV operation. The structure-based methods are, widely applied in most literature, based on local feature matching between a query image that needs to be localized and a reference image with a known pose and feature points. However, the existing methods still struggle with the different illumination and seasonal changes. In outdoor regions, the feature points and descriptors are similar, and the number of mismatches will increase rapidly, leading to the visual positioning becoming unreliable. Moreover, with the database growing, the image retrieval and feature matching are time-consuming. Therefore, in this paper, we propose a novel hierarchical visual positioning method, which includes map construction, landmark matching and pose calculation. First, we combine brain-inspired mechanisms and landmarks to construct a cognitive map, which can make image retrieval efficient. Second, the graph neural network is utilized to learn the inner relations of the feature points. To improve matching accuracy, the network uses the semantic confidence in matching score calculations. Besides, the system can eliminate the mismatches by analyzing all the matching results in the same landmark. Finally, we calculate the pose by using a PnP solver. Furthermore, we evaluate both the matching algorithm and the visual positioning method experimentally in the simulation datasets, where the matching algorithm performs better in some scenes. The results demonstrate that the retrieval time can be shortened by three-thirds with an average positioning error of 10.8 m.

Abstract
OBJECTIVE To investigate the expression and localization of metabotropic glutamate receptors 7 and 8 (mGluR7/8) in rat superior cervical ganglion (SCG) and their changes in response to chronic intermittent hypoxia (CIH). METHODS We detected the expressions of mGluR7 and mGluR8 in the SCG of 8-week-old male SD rats using immunohistochemistry and characterized their distribution with immunofluorescence staining. The expression of mGluR7 and mGluR8 in the cytoplasm and nucleus was detected using Western blotting. A 6-week CIH rat model was established by exposure to intermittent hypoxia (6% oxygen for 30 s followed by normoxia for 4 min) for 8 h daily, and the changes in systolic blood pressure, diastolic blood pressure and mean arterial pressure were measured. The effect of CIH on expression levels of mGluR7 and mGluR8 in the SCG was analyzed using Western blotting. RESULTS Positive expressions of mGluR7 and mGluR8 were detected in rat SCG. mGluR7 was distributed in the neurons and small fluorescent (SIF) cells with positive staining in both the cytoplasm and nuclei, but not expressed in satellite glial cells (SGCs), nerve fibers or blood vessels; mGluR8 was localized in the cytoplasm of neurons and SIF cells, but not expressed in SGCs, nerve fibers, or blood vessels. Western blotting of the nuclear and cytoplasmic fractions of rat SCG further confirmed that mGluR7 was expressed in both the cytoplasm and the nucleus, while mGluR8 exists only in the cytoplasm. Exposure to CIH significantly increased systolic blood pressure, diastolic blood pressure and mean arterial pressure of the rats (all P < 0.001) and augmented the protein expressions of mGluR7 and mGluR8 in the SCG (P < 0.05). CONCLUSION mGluR7 and mGluR8 are present in rat SCG but with different localization patterns. CIH increases blood pressure of rats and enhanced protein expressions of mGluR7 and mGluR8 in rat SCG.

Abstract
BACKGROUND AND PURPOSE Highly predictive markers of drug treatment outcomes of tuberous sclerosis complex-related epilepsy are a key unmet clinical need. The objective of this study was to identify meaningful clinical and radiomic predictors of outcomes of epilepsy drug treatment in patients with tuberous sclerosis complex. MATERIALS AND METHODS A total of 105 children with tuberous sclerosis complex-related epilepsy were enrolled in this retrospective study. The pretreatment baseline predictors that were used to predict drug treatment outcomes included patient demographic and clinical information, gene data, electroencephalogram data, and radiomic features that were extracted from pretreatment MR imaging scans. The Spearman correlation coefficient and least absolute shrinkage and selection operator were calculated to select the most relevant features for the drug treatment outcome to build a comprehensive model with radiomic and clinical features for clinical application. RESULTS Four MR imaging-based radiomic features and 5 key clinical features were selected to predict the drug treatment outcome. Good discriminative performances were achieved in testing cohorts (area under the curve = 0.85, accuracy = 80.0%, sensitivity = 0.75, and specificity = 0.83) for the epilepsy drug treatment outcome. The model of radiomic and clinical features resulted in favorable calibration curves in all cohorts. CONCLUSIONS Our results suggested that the radiomic and clinical features model may predict the epilepsy drug treatment outcome. Age of onset, infantile spasms, antiseizure medication numbers, epileptiform discharge in left parieto-occipital area of electroencephalography, and gene mutation type are the key clinical factors to predict the epilepsy drug treatment outcome. The texture and first-order statistic features are the most valuable radiomic features for predicting drug treatment outcomes.

Abstract
China is rich in antimony, boron, and vanadium mineral resources, which have been detected in environmental water bodies and drinking water. During the revision process of the "Standards for Drinking Water Quality (GB5749-2006)", research and evaluation are focused on three indicators: antimony, boron and vanadium. Vanadium is added and the limit value of boron is adjusted. This study reviews and discusses the technical contents related to the revision of the antimony, boron and vanadium, including the environmental presence levels, exposure status, health effects, and the revision of the standard limits of these three indicators. Suggestions are also made for the implementation of this standard.

Abstract
Herein, hydrogen (H·) radical was observed as a new pathway to produce hydroxyl (OH·) radicals that promoted cadmium sulfide (CdS) dissolution and thus Cd solubility in paddy soils. In soil incubation experiments, the bioavailable Cd concentrations in flooded paddy soils were increased by 8.44 % as the soil was aerated for 3d. For the first time, the H· radical was observed in aerated soil sludge. The association of CdS dissolution with free radicals was thereafter confirmed in an electrolysis experiment. Both H· and OH· radicals in electrolyzed water were confirmed by the electron paramagnetic resonance analysis. In the system with CdS, water electrolysis increased soluble Cd2+ concentration by 60.92 times, which was compromised by 43.2 % when the radical scavenger was introduced. This confirmed the free radicals can lead to oxidative dissolution of CdS. The H· radical was generated in systems with fulvic acid or catechol irradiated by ultraviolet lights, indicating soil organic carbon could be an important precursor for H· and OH· radicals. Biochar application decreased soil DTPA-Cd by 22-56 % invoking mechanisms besides adsorption. First, biochar quenched radicals and reduced CdS dissolution by 23.6 % in electrolyzed water in which -C-OH of biochar was oxidized to CO. Second, biochar boosted Fe/S-reducing bacteria and thus compromised CdS dissolution, as affirmed by a reversal correlation between soil available Fe2+ and DTPA-Cd concentrations. A similar phenomenon occurred in Shewanella oneidensis MR-1-inoculated soils. This study provided new insights into the bioavailability of Cd and offered feasible measures to remediate Cd-contaminated paddy soils with biochars.

Abstract
Objective: To observe the present situation, efficacy and safety of immunotherapy in patients with malignant pleural mesothelioma (MPM). Methods: The data of 39 patients with MPM in two centers from 2016 to 2021 were collected and the efficacy and safety were evaluated. According to the application of immune checkpoint inhibitors (ICIs), these patients, whose median clinical follow-up amounting to 18.97 months, were divided into immunotherapy group (19 cases) and control group (20 cases). Kaplan-Meier method and Log-rank test were used for the survival analysis. Results: The objective response rate (ORR) and the disease control rate (DCR) in the immunotherapy group is 21.05% and 79.0% respectively, compared with 10.0% and 55.0% in the control group; and the difference was not statistically significant (P>0.05). The median overall survival (OS) in the immunotherapy group was significantly longer than that in the control group (14.53 months vs 7.07 months, P=0.015), but there was no significant difference in the median progression free survival (PFS) between two groups (4.80 months vs 2.03 months, P=0.062). Single factor survival analysis showed that the nature of pleural effusion, pathological subtype and the efficacy of immunotherapy were related to both PFS and OS of the patients with MPM (P<0.05). The incidence of adverse reactions in immunotherapy group was 89.5% (17 out of 19 cases), and the most common adverse event was hematological toxicity (9 cases), followed by nausea and vomiting (7 cases), fatigue (6 cases) and skin damage (6 cases). Five patients had immune checkpoint inhibitors (ICIs) related adverse reactions with grade 1-2. Conclusions: Patients with MPM have begun to receive immunotherapy in more than 2-line mainly combined chemotherapy in the real world, and the median treatment line is 2-line. Either combined with chemotherapy or anti-angiogenesis therapy, ICI inhibitors have significant efficacy, controllable adverse events and good clinical value.

Abstract
Background Spinal motoneurons may become hyperexcitable after a stroke. Knowledge about motoneuron hyperexcitability remains clinically important as it may contribute to a number of phenomena including spasticity, flexion synergies, and abnormal limb postures. Hyperexcitability seems to occur more often in muscles that flex the wrist and fingers (forearm flexors) compared to other upper limb muscles. The cause of hyperexcitability remains uncertain but may involve plastic changes in motoneurons and their axons. Aim To characterize intrinsic membrane properties of flexor carpi radialis (FCR) motor axons after stroke using nerve excitability testing. Methods Nerve excitability testing using threshold tracking techniques was applied to characterize FCR motor axon properties in persons who suffered a first-time unilateral cortical/subcortical stroke 23 to 308 days earlier. The median nerve was stimulated at the elbow bilaterally in 16 male stroke subjects (51.4 ± 2.9 y) with compound muscle action potentials recorded from the FCR. Nineteen age-matched males (52.7 ± 2.4 y) were also tested to serve as controls. Results Axon parameters after stroke were consistent with bilateral hyperpolarization of the resting potential. Nonparetic and paretic side axons were modeled by a 2.6-fold increase in pump currents (IPumpNI) together with an increase (38%-33%) in internodal leak conductance (GLkI) and a decrease (23%-29%) in internodal H conductance (Ih) relative to control axons. A decrease (14%) in Na+ channel inactivation rate (Aah) was also needed to fit the paretic axon recovery cycle. "Fanning out" of threshold electrotonus and the resting I/V slope (stroke limbs combined) correlated with blood potassium [K+] (R = -0.61 to 0.62, p< 0.01) and disability (R = -0.58 to 0.55, p < 0.05), but not with spasticity, grip strength, or maximal FCR activity. Conclusion In contrast to our expectations, FCR axons were not hyperexcitable after stroke. Rather, FCR axons were found to be hyperpolarized bilaterally post stroke, and this was associated with disability and [K+]. Reduced FCR axon excitability may represent a kind of bilateral trans-synaptic homeostatic mechanism that acts to minimize motoneuron hyperexcitability.

Abstract
The remediation of heavy metals contaminated soils is of great significance for reducing their risk to human health. Here, pristine pinewood sawdust biochar (BC) and phosphate-functionalized biochar (PBC) were conducted to investigate their immobilization performance towards lead (Pb) and cadmium (Cd) in arable soil severely polluted by Pb (9240.5 mg kg-1) and Cd (10.71 mg kg-1) and microbial response in soil. Compared to pristine BC (2.6-12.1%), PBC was more effective in immobilizing Pb and Cd with an immobilization effectiveness of 45.2-96.2% after incubation of 60 days. Moreover, the labile Pb and Cd in soils were transformed to more stable species after addition of PBC, reducing their bioavailability. The immobilization mechanisms of Pb and Cd by PBC were mainly to facilitate the formation of stable phosphate precipitates e.g., Cd3(PO4)2, Cd5(PO4)3OH, Cd5H2(PO4)4‧4H2O, and pyromorphite-type minerals. Further, PBC increased pH, organic matter, cation exchange capacity, and available nutrients (phosphorus and potassium) in soils. High-throughput sequencing analysis of 16 S rRNA genes indicated that the diversity and composition of bacterial community responded to PBC addition due to PBC-induced changes in soil physicochemical properties, increasing the relative abundance of beneficial bacteria (e.g., Brevundimonas, Bacillus, and norank_f__chitinophagaceae) in the treated soils. What's more, these beneficial bacteria could not only facilitate Pb and Cd immobilization but also alter nutrient biogeochemical transformation (nitrogen and iron) in co-contaminated soils. Overall, PBC could be a promising material for immobilization of Pb and Cd and the simultaneous enhancement of soil quality and available nutrients in co-contaminated soils.

Abstract
Anterior chamber paracentesis (ACP) is a commonly used ophthalmic technique with broad clinical applications. It plays an important role in the diagnosis of intraocular infections, vitreoretinal lymphoma, and other diseases. However, the current ACP methods used in clinical practice have some issues and potential risks. There is no unified standard for the procedural steps, environment, and perioperative management. Therefore, this article provides a systematic review of various methods and devices for ACP and briefly summarizes the current clinical ACP environment, perioperative management, and safety considerations. The aim of this review is to provide insights into the current status and future prospects of ACP, with the goal of optimizing the safety and efficacy of this technique.

Abstract
Polycarbonate (PC) foam is a versatile material with excellent properties, but its low thermal stability limits its application in high-temperature environments. The aim of this study was to improve the thermal stability of PC foam by adding glass fibers (GF) and to investigate the effect of GF on PC crystallization behavior and PC foam cell morphology. This study was motivated by the need to improve the performance of PC foams in various industries, such as construction, automotive, and medical. To achieve this goal, PC/GF composites were prepared by extrusion, and PC/GF composite foams were produced using a batch foaming process with supercritical carbon dioxide (SC-CO2) as the blowing agent. The results showed that the addition of GF accelerated the SC-CO2-induced crystallization stability of PC and significantly increased the cell density to 4.6 cells/cm3. In addition, the thermal stability of PC/GF foam was improved, with a significant increase in the residual carbon rate at 700 °C and a lower weight loss rate than PC matrix. Overall, this study highlights the potential of GF as a PC foam reinforcement and its effect on thermal and structural properties, providing guidance for industrial production and applications.

Abstract
OBJECTIVE First-pass effect (FPE), defined as successful reperfusion (modified Thrombolysis in Cerebral Infarction score 2b-3) with a single stent retriever attempt without salvage treatment, has not been fully identified in patients with acute basilar artery occlusion (BAO). The authors' aim was to assess the impact of FPE on efficacy and safety for patients with BAO. METHODS The authors included data from the Acute Basilar Artery Occlusion Study (BASILAR) about patients who underwent mechanical thrombectomy within 24 hours after symptom onset and compared the clinical outcomes of patients who achieved FPE with those who did not. In addition, the authors further compared outcomes between patients with FPE and those with final successful reperfusion achieved with salvage treatment. The primary clinical outcome was favorable outcome (modified Rankin Scale score ≤ 3). RESULTS Among 471 enrolled patients, FPE was achieved in 83 (17.6%) who underwent acute BAO thrombectomy. FPE was strongly associated with favorable outcome (adjusted OR 2.84, 95% CI 1.56-5.16, p = 0.001), lower rate of mortality (28.9% of FPE patients vs 48.2% of non-FPE patients, p = 0.001), and shorter median time from groin puncture to recanalization (65 minutes vs 110 minutes, p < 0.001). Occlusion site of the distal basilar artery, cardioembolism, and undetermined etiology were positive predictors of FPE, whereas baseline National Institutes of Health Stroke Scale score was a negative predictor. Compared with final successful reperfusion, FPE also contributed independently to favorable outcomes (adjusted OR 2.25, 95% CI 1.23-4.10, p = 0.008). CONCLUSIONS FPE was associated with 90-day favorable outcome in patients with acute BAO who underwent stent retriever thrombectomy within 24 hours. Clinical trial registration no.: ChiCTR1800014759 (www.chictr.org.cn).

Abstract
Herein, a one-step co-pyrolysis protocol was adopted for the first time to prepare a novel pyrogenic carbon-Cu0/Fe3O4 heteroatoms (FCBC) in CO2 ambiance to discern the roles of each component in PDS activation. During co-pyrolysis, CO2 catalyzed formation of reducing gases by biomass which facilitated reductive transformation of Fe3+ and Cu2+ to Cu0 and Fe3O4, respectively. According to the analysis, the resulting metal (oxide) catalyzed graphitization of biocharand decomposition of volatile substances resulting in an unprecedented surface area (1240 m2/g). The resulting FCBC showed greater structural defects and less electrical impedance. Batch experiments indicated that Rhodamine B (RhB) degradation by FCBC (100%) was superior to Fe3O4 (50%) and Cu0/Fe3O4 (76.4%) in persulfate (PDS) system, which maintained reasonable efficiency (75.6%-63.6%) within three cycles. The reactive oxygen species (ROS) associated with RhB degradation was identified by an electron paramagnetic resonance and confirmed by scavenging experiments. RhB degradation invoked both (sulfate and dominantly hydroxyl) radical and non-radical (singlet oxygen, 1O2) pathways. Regarding FCBC, Cu0 can continuously react with Fe3+ in Fe3O4 to generate larger quantities of Fe2+, and both Cu0 and Fe2+ activated PDS to yield sulfate radicals which was quickly converted to hydroxyl radical. Besides, Cu0/Cu2+ could complex with PDS to form a metastable complex, which particularly contributed to 1O2 generation. These cascade reactions by FCBC were reinforced by carbonyl group of biochar and favorable electron transfer ability. This work highlighted a new approach to prepare a magnetic and environment-benign heterogonous catalyst to remove organic pollutants in water.

Abstract
CONTEXT Insomnia is associated with insulin resistance (IR) in observational studies, however, whether insomnia is causally associated with IR remains unestablished. OBJECTIVE This study aims to estimate the causal associations of insomnia with IR and its related traits. METHODS In primary analyses, multivariable regression (MVR) and one-sample Mendelian randomization (1SMR) analyses were performed to estimate the associations of insomnia with IR (triglyceride-glucose [TyG] index and triglyceride to high-density lipoprotein cholesterol [TG/HDL-C] ratio) and its related traits (glucose level, TG, and HDL-C) in UK Biobank. Thereafter, two-sample MR (2SMR) analyses were used to validate the findings from primary analyses. Finally, the potential mediating effects of IR on the pathway of insomnia giving rise to T2D were examined using a two-step MR design. RESULTS Across the MVR, 1SMR, and their sensitivity analyses, we found consistent evidence suggesting that more frequent insomnia symptoms were significantly associated with higher values of TyG index (MVR: β = 0.024, P < 2.00E-16; 1SMR: β = 0.343, P < 2.00E-16), TG/HDL-C ratio (MVR: β = 0.016, P = 1.75E-13; 1SMR: β = 0.445, P < 2.00E-16), and TG level (MVR: β = 0.019 log mg/dl, P < 2.00E-16; 1SMR: β = 0.289 log mg/dL, P < 2.00E-16) after Bonferroni adjustment. Similar evidence was obtained by using 2SMR, and mediation analysis suggested that about a quarter (25.21%) of the association between insomnia symptoms and T2D was mediated by IR. CONCLUSIONS This study provides robust evidence supporting that more frequent insomnia symptoms are associated with IR and its related traits across different angles. These findings indicate that insomnia symptoms can be served as a promising target to improve IR and prevent subsequent T2D.

Abstract
OBJECTIVES To develop and validate a nomogram to detect improved knee pain in osteoarthritis (OA) by integrating magnetic resonance imaging (MRI) radiomics signature of subchondral bone and clinical characteristics. METHODS Participants were selected from the Vitamin D Effects on Osteoarthritis (VIDEO) study. The primary outcome was 20% improvement of knee pain score over 2 years in participants administrated either vitamin D or placebo. Radiomics features of subchondral bone and clinical characteristics from 216 participants were extracted and analyzed. The participants were randomly split into the training and validation cohorts at a ratio of 8:2. Least absolute shrinkage and selection operator (LASSO) regression was used to select features and generate radiomics signatures. The optimal radiomics signature and clinical indicators were fitted into a nomogram using multivariable logistic regression model. RESULTS The nomogram showed favorable discrimination performance [AUCtraining, 0.79 (95% CI: 0.72-0.79), AUCvalidation, 0.83 (95% CI: 0.70-0.96)] as well as a good calibration. Additional contributing value of fusion radiomics signature to the nomogram was statistically significant (NRI, 0.23; IDI, 0.14, P < 0.001 in training cohort and NRI, 0.29; IDI, 0.18, P < 0.05 in validating cohort). Decision curve analysis confirmed the clinical usefulness of nomogram. CONCLUSION The radiomics-based nomogram comprising the MR radiomics signature and clinical variables achieves a favorable predictive efficacy and accuracy in differentiating improvement in knee pain among OA patients. This proof-of-concept study provides a promising way to predict clinically meaningful outcomes.

Abstract
Purpose: To explore the surgical outcomes of the macular microvasculature and visual function in eyes with idiopathic epiretinal membrane (iERM) using spectral-domain optical coherence tomography angiography (SD-OCTA). Methods: This observational, cross-sectional study included 41 participants who underwent iERM surgery with a 3-month (3M) follow-up. Forty-one healthy eyes formed the control group. The assessments included best-corrected visual acuity (BCVA) and mean sensitivity (MS) by microperimetry and SD-OCTA assessment of vessel tortuosity (VT), vessel density (VD), foveal avascular zone, and retinal thickness (RT). Results: The findings showed statistically significant differences in VT, foveal avascular zone parameters, RT, BCVA, and MS between the iERM and control groups (p < 0.05). After iERM surgery, the macular VT, SCP VD, and RT decreased significantly (p < 0.01) while the DCP VD increased (p = 0.029). The BCVA improved significantly (p < 0.001) and was associated with the MS (rs = -0.377, p = 0.015). MS was associated with the SCP VD and RT at 3M (SCP VD rs = 0.511, p = 0.001; RT rs = 0.456, p = 0.003). In the superior quadrant, the MS improved significantly (p < 0.001) and the improvement of MS was associated with the reduction of VT (β = -0.330, p = 0.034). Conclusion: Microcirculatory remodeling and perfusion recovery were observed within 3 months after iERM surgery. VT was a novel index for evaluating the morphology of the retinal microvasculature in eyes with iERM and was associated with MS in the superior quadrant.

Abstract
OBJECTIVES The relationship between sarcopenia and cognitive function has been extensively studied, but is usually explored at a single time point. We used repeatedly measured cognitive data to examine the relationship between sarcopenia and cognitive trajectories over time among middle-aged and older Chinese adults. DESIGN A nationally representative cohort study. SETTING AND PARTICIPANTS Data were from three waves (2011, 2013 and 2015) of the China Health and Retirement Longitudinal Study (CHARLS). A total of 8963 participants with complete baseline data (wave 1) and at least two cognitive function tests (waves 1-3) were enrolled in this study. MEASUREMENTS Sarcopenia was diagnosed at baseline (wave 1). The wave 1-3 data were used to analyze cognitive trajectories over time by constructing a latent class trajectory model (LCTM). Logistic regression model was used to analyze the association between sarcopenia and cognitive trajectories. RESULTS Among 8693 participants, we identified two trajectories of cognitive function development, including a persistent low trajectory (n= 4856, 55.86%) and a persistent high trajectory (n= 3837, 44.14%). Sarcopenia was associated with persistently low cognitive trajectory of global cognitive (OR: 1.248, 95%CI: 1.046-1.490) after adjustment for other covariates. This association was still observed when stratified by age, gender, educational level, marital status, social activity, smoking status and drinking status. Mediation analysis showed that body mass index (BMI) mediated efficacy accounting for 42.32% of the relationship. CONCLUSIONS Our study showed two trajectory groups of global cognitive function. Sarcopenia was associated with a persistent low trajectory over time and BMI mediated the relationship between sarcopenia and cognitive trajectories among middle-aged and older Chinese adults.

Abstract
OBJECTIVE The aim of this study was to investigate the efficacy and safety of endovascular treatment (EVT) plus standard medical treatment (SMT) in patients with acute basilar artery occlusion (BAO) within 6 hours of the estimated occlusion time, based on a Chinese population. METHODS The authors selected patients from the Endovascular Treatment of Acute Basilar Artery Occlusion Study (BASILAR) registry, which was a nationwide prospective registry, within 6 hours after the estimated time of onset of a stroke in acute BAO. Patients were divided into the SMT-alone group or the EVT+SMT group according to treatment modalities. The primary outcome was a favorable functional outcome, defined as a modified Rankin Scale score between 0 and 3 at 90 days. Safety outcomes included death at 90 days and symptomatic intracerebral hemorrhage. RESULTS The authors assessed 590 patients for eligibility. Of these patients, 127 received SMT alone and 463 were treated with EVT plus SMT. EVT was associated with a higher rate of a favorable functional outcome (adjusted OR 3.804, 95% CI 1.890-7.658; p < 0.001) and a lower proportion of deaths at 90 days (adjusted OR 0.364, 95% CI 0.223-0.594; p < 0.001). Lower age (adjusted OR 0.978, 95% CI 0.960-0.997; p = 0.022); lower baseline National Institutes of Health Stroke Scale score (adjusted OR 0.926, 95% CI 0.902-0.950; p < 0.001); higher baseline posterior circulation Alberta Stroke Program Early CT Score (adjusted OR 1.681, 95% CI 1.424-1.984; p < 0.001); absence of diabetes mellitus (adjusted OR 0.482, 95% CI 0.267-0.871; p = 0.016); and modified Thrombolysis in Cerebral Infarction scores 2b-3 (adjusted OR 5.117, 95% CI 2.304-11.367; p < 0.001) were independent factors for a favorable outcome in the EVT+SMT group. CONCLUSIONS Based on the study design, patients with acute BAO who received EVT within 6 hours were associated with improved favorable outcome and decreased deaths compared with patients who received SMT. Predictors of desirable outcome in patients undergoing EVT included lower age, lower baseline National Institutes of Health Stroke Scale score, higher baseline posterior circulation Alberta Stroke Program Early CT Score, absence of diabetes mellitus, and modified Thrombolysis in Cerebral Infarction scores 2b-3.

Abstract
Objective: To examine the antioxidant effect of low dosage insulin glargine intervention at different time in rats with delayed resuscitation after burn, in order to acquire a better time of antioxidant intervention during delayed resuscitation following burn injury. Methods: With 10 rats in each group, 50 male SD rats were assigned to sham injury group, delayed resuscitation group, immediate post-burn insulin glargine treatment group (immediate treatment group), 2 hours post-burn insulin glargine treatment group(2 h treatment group), and 6 hours post-burn insulin treatment group(6 h treatment group) with random number table. Each treatment group received subcutaneous injections of insulin glargine (1.0 U·kg-1·d-1) immediately, two hours and six hours after the burn, while the delayed resuscitation group received the same amount of normal saline six hours after the burn. To imitate delayed fluid resuscitation, the delayed resuscitation group and each therapy group were intraperitoneally injected with normal saline (40 ml/kg) 6 hours after injury. No medicine and fluid resuscitation was administered to the sham injury group. Rats in the sham injury group had their abdominal aortic blood, hearts, and kidney tissues collected immediately after injury, while rats in the other groups had their blood and tissues collected 24 hours later. To analyze the timing of antioxidant intervention, the activities of CuZn-superoxide dismutase (CuZn-SOD), catalase (CAT), glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), xanthine oxidase (XOD) and myeloperoxidase (MPO) in blood glucose and myocardial and renal tissues were measured by spectrophotometry. Results: Compared with the sham group, blood glucose levels in the delayed resuscitation group increased [(10.72±0.80) vs (6.57±0.82)mmol/L,P<0.001], while in the myocardium and kidney, the activities of CuZn-SOD, CAT, GSH-Px and T-AOC decreased (all P<0.05) and the activities of XOD and MPO increased (all P<0.05). Compared with the delayed resuscitation group, blood glucose decreased in the immediate, 2 h, and 6 h treatment groups (all P<0.05). In the immediate and 2 h treatment group, the activities of CuZn-SOD, CAT, GSH-Px and T-AOC in the myocardium and kidney increased(all P<0.05). In the 6 h treatment group, only the activities of GSH-Px in myocardium, CAT and GSH-Px in kidney increased (all P<0.05). Compared with the delayed resuscitation group, in the immediate treatment group, the activities of MPO and XOD in myocardial tissue and XOD in renal tissue decreased (all P<0.05). The activities of MPO and XOD in myocardial and renal tissues of the 2 h treatment group both decreased (all P<0.05). In the 6 h treatment group, the activities of MPO in myocardial tissue and XOD in renal tissue both decreased (all P<0.05). Compared with the immediate treatment group, the activity of GSH-Px in myocardial tissue increased (P<0.05), and the activities of CuZn-SOD, CAT, GSH-Px and T-AOC in renal tissue increased in the 2 h treatment group (all P<0.05). The activities of CuZn-SOD, CAT, GSH-Px and T-AOC in myocardium of 6 h treatment group decreased (all P<0.05). Compared with the immediate treatment group, the activities of XOD and MPO in myocardial tissue and XOD in renal tissue of the 2 h treatment group had no significant difference (all P>0.05), but the activity of MPO in renal tissue decreased (P<0.05). The activities of XOD and MPO in myocardial tissue of the 6 h treatment group increased (all P<0.05). Compared with the 2 h treatment group, the activities of CuZn-SOD, CAT and GSH-Px and T-AOC in myocardium and kidney tissues in the 6 h treatment group decreased (all P<0.05), while the activities of XOD and MPO in myocardium and kidney tissues increased [myocardium: (374±8) vs (290±19) U/g, (0.021 8±0.003 9) vs (0.010 7±0.002 4) U/g, kidney: (157±6) vs (128±9) U/g, (0.026 8±0.004 3) vs (0.013 4±0.003 1) U/g, all P<0.05]. Conclusions: The timing of the intervention is related to the antioxidant effect of insulin glargine during delayed burn resuscitation. The intervention immediately and 2 hours after burn could have a better antioxidant effect compared to the intervention at 6 hours after burn.

Abstract
BACKGROUND The drug 3-n-butylphthalide (NBP) was developed and approved in China, where it has been used to treat ischemic cerebrovascular diseases. It is also considered to have a neuroprotective effect. This study aimed to evaluate whether NBP combined with endovascular treatment (EVT) can improve the clinical outcome and safety in patients with acute ischemic stroke (AIS) due to large vessel occlusion (LVO). METHODS Data from three studies of patients treated with EVT for AIS due to LVO were combined in this study. Patients of LVO undergoing EVT were dichotomized into NBP and non-NBP subgroups. The primary efficacy outcome was the shift of the modified Rankin Scale (mRS) score at 90 days. The secondary efficacy outcome included favorable functional outcomes, functional independence, and excellent outcome (defined as an mRS score of 3 or less) at 90 days. Safety outcomes included mortality within 90 days and symptomatic intracranial hemorrhage (sICH) within 48 h. RESULTS A total of 1820 patients undergoing EVT were included in this study; 628 (37.5%) patients received NBP treatment, whereas 1138 (62.5%) did not. After adjusting for multiple factors, NBP was associated with the improvement of functional outcomes at 90 days (adjusted common odds ratio [OR]: 1.503; 95% confidence interval (CI): 1.254-1.801; p < 0.001). NBP was associated with a higher rate of 90-day favorable outcomes (adjusted OR: 1.589; 95% CI: 1.251-2.020; p < 0.001) and a lower rate of 90-day mortality (adjusted OR: 0.486 [95% CI: 0.372-0.635]; p < 0.001). sICH occurred in 74 of 682 (10.9%) patients in the NBP group and 155 of 1126 (13.8%) patients in the non-NBP group; no statistical difference was detected (adjusted OR: 0.787 [95% CI: 0.567-1.092]; p = 0.152). CONCLUSION Among patients with AIS due to LVO, NBP combined with EVT is associated with better functional outcomes and reduced mortality risk without increasing the risk of sICH.

Abstract
Thermal noise in test mass substrates and coatings is a significant noise contribution in the detection band of current and proposed future gravitational wave detectors. Substrate thermal noise can be reduced by using high mechanical Q-factor materials and cooling the test mass mirrors. Silicon is a promising potential candidate for the next generation detector test masses. The low thermal expansion and high thermal conductivity of silicon allow efficient cryogenic operation, and a significant increase in the amount of optical power that can be used in the detectors by decreasing thermal deformation and aberration. Mechanical stress, damage, poor surface quality or contamination can result in increased loss and thermal noise. Therefore, the characterization of mechanical loss in silicon test masses is necessary. In this project, we developed a technique to measure high Q-factor mechanical modes. We used finite element modeling to optimize the design of the test mass support structure to minimize the loss coupling from the support structure over a wide frequency range. Mechanical Q-factors of the order of 107 were achieved for several modes of a 10 cm diam. × 3 cm cylindrical silicon test mass with such a support at room temperature.

Abstract
Hyperphosphorylation of the microtubule associated protein tau is associated with several neurodegenerative diseases including Alzheimer's Disease (AD), collectively referred to as tauopathies. However, the mechanisms by which tau is linked to synaptic dysfunction and memory impairment remain unclear. To address this question, we constructed a mouse model with brain-specific deficiency of SIRT1 (SIRT1 flox/Cre + ). Here, we show that increase of site-specific phosphorylation of tau is coupled with the strengthened O-GlcNAcylation of tau triggered by reduced O-GlcNAcase (OGA) and increased O-GlcNAc transferase (OGT) protein level in the brain of SIRT1 flox/Cre+ mice. SIRT1 deletion in mice brain changes the synaptosomal distribution of site-specific phospho-tau. Learning and memory deficiency induced by dendritic spine deficits and synaptic dysfunction are revealed via SIRT1 flox/Cre+ mice. Our results provide evidence for SIRT1 as a potential therapeutic target in clinical tauopathies.

Abstract
Objective: To analyze the morphological changes of gray matter in clefts lip and palate (CLP) children using voxel-based morphometric (VBM) and surface-based morphometric (SBM) methods. So as to provide a reference for the neural mechanism of cleft palate speech disorder (CPSD) in CLP population. Methods: A total of 29 CLP children with CPSD who were admitted to Department of Oral & Maxillofacial Plastic & Tramuma Surgery, Capital Medical University School of Stomatology from January 2017 to January 2022 were selected (CLP group), including 9 males and 20 females, aged (9.6±3.2) years (5-17 years old). During the same period, 33 healthy children (healthy control group) were recruited in Beijing Children's Hospital, including 9 males and 24 females, aged (9.6±2.4) years (5-16 years). Results: There were no significant differences in age and gender between the healthy control group and the CLP group (t=-0.07, P=0.944; χ2=0.11, P=0.745). Compared with the healthy control group, the left inferior temporal gyrus, right inferior parietal angular gyrus, and left upper cerebellar gray matter volume in the CLP group were significantly decreased (P<0.05), and the volume of the right medial superior frontal gyrus was significantly increased (P<0.05). The left inferior frontal gyrus insula and the right insula cortical thickness of the subjects in the CLP group were significantly thinner [family-wise error rate (FWER) correction, P=0.035]. The right hemisphere cingulate gyrus isthmus sulcus index increased in the CLP group (FWER correction, P=0.040). Conclusions: CLP children with speech disorder have multiple language-related brain regions with reduced gray matter (GM) volume, decreased cortical thickness, and increased gyrificaition index. The abnormal changes in GM morphology in these brain regions may be related to the characteristics of cleft palate speech disorder in the CLP population.
