Abstract
Quantitative analysis of irregular anatomical structures is crucial in oral medicine, but clinicians often typically measure only several representative indicators within the structure as references. Deep learning semantic segmentation offers the potential for entire quantitative analysis. However, challenges persist, including segmentation difficulties due to unclear boundaries and acquiring measurement landmarks for clinical needs in entire quantitative analysis. Taking the palatal alveolar bone as an example, we proposed an artificial intelligence measurement tool for the entire quantitative analysis of irregular dental structures. To expand the applicability, we have included lightweight networks with fewer parameters and lower computational demands. Our approach finally used the lightweight model LU-Net, addressing segmentation challenges caused by unclear boundaries through a compensation module. Additional enamel segmentation was conducted to establish a measurement coordinate system. Ultimately, we presented the entire quantitative information within the structure in a manner that meets clinical needs. The tool achieved excellent segmentation results, manifested by high Dice coefficients (0.934 and 0.949), intersection over union (0.888 and 0.907), and area under the curve (0.943 and 0.949) for palatal alveolar bone and enamel in the test set. In subsequent measurements, the tool visualizes the quantitative information within the target structure by scatter plots. When comparing the measurements against representative indicators, the tool's measurement results show no statistically significant difference from the ground truth, with small mean absolute error, root mean squared error, and errors interval. Bland-Altman plots and intraclass correlation coefficients indicate the satisfactory agreement compared with manual measurements. We proposed a novel intelligent approach to address the entire quantitative analysis of irregular image structures in the clinical setting. This contributes to enabling clinicians to swiftly and comprehensively grasp structural features, facilitating the design of more personalized treatment plans for different patients, enhancing clinical efficiency and treatment success rates in turn.

Abstract
OBJECTIVE To investigate the seroprevalence of Toxoplasma gondii infections among patients with hematological diseases, so as to provide insights into improving the prognosis and quality of life among patients with hematological diseases. METHODS A total of 240 patients with hematological diseases (including 170 patients with hematological tumors and 70 patients with non-tumor hematological diseases) admitted to The Affiliated Hospital of Putian University during the period from January 1, 2021 through October 10, 2023 and 500 healthy volunteers in the hospital during the same period were enrolled. Subjects' demographics and serum samples were collected, and serum specific IgG and IgM antibodies against T. gondii were detected using the chemiluminescence assay, with any of a positive IgG or IgM antibody defined as a positive T. gondii infection. The seroprevalence of specific IgG and IgM antibodies against T. gondii was compared between patients with hematological diseases and healthy volunteers. RESULTS The mean age (F = 2.034, P > 0.05) and gender distribution (χ2 = 0.462, P > 0.05) were comparable among patients with hematological tumors, patients with non-tumor hematological diseases and healthy volunteers, and there was no significant difference in the proportion of history of cat or dog contacts between patients with hematological diseases and healthy volunteers (χ2 = 0, P > 0.05). The seroprevalence of anti-T. gondii antibody was significantly higher among patients with hematological diseases than among healthy volunteers (15.8% vs. 0.6%; χ2 = 71.902, P < 0.01), and there was a significant difference in the seroprevalence of anti-T. gondii antibody among patients with hematological tumors (18.2%), patients with non-tumor hematological diseases (10.0%) and healthy volunteers (χ2 = 78.327, P < 0.01). The seroprevalence of anti-T. gondii antibody was significantly higher among patients with hematological tumors and non-tumor hematological diseases than among healthy volunteers (both P values < 0.05), while no significant difference was seen in the seroprevalence of anti-T. gondii antibody between patients with hematological tumors and non-tumor hematological diseases (P > 0.05). In addition, the proportion of history of cat or dog contacts was significantly higher among patients with hematological diseases that were positive for serum anti-T. gondii anti-body than among those negative for serum anti-T. gondii antibody (21.1% vs. 5.4%; χ2 = 8.653, P < 0.05). CONCLUSIONS There is a high seroprevalene rate of T. gondii infections among hematological diseases, which is significantly greater than that among healthy volunteers.

Abstract
1. This study investigated the effects of lysolecithins (LL) on performance, egg quality, blood profiles, relative organ weight and liver histopathology in laying hens.2. A total of 480 healthy 65-week-old Lohmann laying hens were randomly allocated into four treatments in a 2 × 2 factorial arrangement design with two levels of energy (AMEn, 11.08 MJ/kg and 12.94 MJ/kg) and two levels of LL (0 and 0.05%).3. Birds fed high energy diets had lower (P < 0.05) average daily intake and feed conversion rate during weeks 0-4, 5-8 and 0-8, but higher (P < 0.05) average egg weight (AEW) during trial weeks 0-4. There was an interaction in (P < 0.05) AEW during trial weeks 0-14 and 0-8 for energy and LL. The high energy diets increased yolk colour at the end of weeks 2 and 4, while addition of LL increased albumen height at the end of week 2. There was an interaction (P < 0.05) in yolk colour between energy and LL at the end of week 2. There was an interaction (P < 0.05) in serum superoxide dismutase and LDL-C throughout the experiment.4. The high energy diets increased (P < 0.05) the relative weight of abdominal fat compared with low energy diets. The high energy diets increased (P < 0.05) liver ether extract content and liver pathological injury score compared with low energy diets at the end of week 8, while the addition of LL decreased (P < 0.05) liver pathological injury score.5. The supplementation of LL in high energy diets could alleviate some negative effects on liver injury in late laying hens.

Abstract
The productivity of smallholder dairy farms is very low in developing countries. Important genetic gains could be realized using genomic selection, but genetic evaluations need to be tailored for lack of pedigree information and very small farm sizes. To accommodate this situation, we propose a flexible Bayesian model for the genetic evaluation of milk yield, which allows us to simultaneously account for nongenetic random effects for farms and varying SNP variance (BayesR model). First, we used simulations based on real genotype data from Indian crossbred dairy cattle to demonstrate that the proposed model can separate the true genetic and nongenetic parameters even for small farm sizes (2 cows on average) although with high standard errors in scenarios with low heritability. The accuracy of genomic genetic evaluation increased until farm size was approximately 5. We then applied the model to real data from 4,655 crossbred cows with 106,109 monthly test day milk records and 689,750 autosomal SNPs. We estimated a heritability of 0.16 (0.04) for milk yield and using cross-validation, a genomic estimated breeding value (GEBV) accuracy of 0.45 and bias (regression of phenotype on GEBV) of 1.04 (0.26). Estimated genetic parameters were very similar using BayesR, BayesC, and genomic BLUP approaches. Candidate genes near the top variants, IMMP2L and ARHGEF2, have been previously associated with milk protein composition, mastitis resistance, and milk cholesterol content. The estimated heritability and GEBV accuracy for milk yield are much lower than those from intensive or pasture-based systems in many countries. Further increases in the number of phenotyped and genotyped animals in farms with at least 2 cows (preferably 3-5, to allow for dropout of cows) are needed to improve the estimation of genetic effects in these smallholder dairy farms.

Abstract
PURPOSE Merkel cell carcinoma (MCC) is a neuroendocrine carcinoma originating in the skin. Studies are needed to determine the mechanisms of immune escape in patients with MCC, and malignant cell conditions that promote immune evasion. METHODS We used Single-cell RNA sequencing (scRNA-seq) to determine cellular features associated with MCC disease trajectory. A longitudinal multi-omics study was performed using scRNA-seq data of peripheral blood harvested from four-time points. Six major cell types and fifteen cell subgroups were identified and confirmed their presence by expression of characteristic markers. The expression patterns and specific changes of different cells at different time points were investigated. Subsequently, bulk RNA data was used to validate key findings. RESULTS The dynamic characteristics of the cells were identified during the critical period between benign improvement and acquisition of resistance. Combined with the results of the validation cohort, the resistance program expressed in the relapse stage is mainly associated with T cell exhaustion and immune cell crosstalk disorder. Coinciding with immune escape, we also identified a decrease non-classical monocytes and an expansion of classical monocytes with features of high inflammation and immune deficiency. CONCLUSION Changes in cellular status, such as depletion of T cells and dysregulation of B cell proliferation and differentiation, may lead to drug resistance in MCC patients. Meanwhile, the widespread decreased antigen presentation ability and immune disorders caused by deletion of MHC class II gene expression should not be ignored.

Abstract
PURPOSE/OBJECTIVE(S) Prostate cancer is the most common non-cutaneous cancer diagnosed among men in the United States, and the majority of patients are diagnosed with localized disease. Men with localized prostate cancer have several treatment options including external beam radiotherapy with either photons or protons. Proton beam therapy (PBT) has certain dosimetric advantages and the potential to reduce treatment-associated morbidity and improve oncologic outcomes, but current PBT is significantly more costly than intensity-modulated radiotherapy (IMRT). The PARTIQoL trial (NCT01617161) is the first multicenter phase 3 randomized trial comparing protons to photons in the treatment of localized prostate cancer. MATERIALS/METHODS Patients with low or intermediate risk prostate cancer (Stage T1c-T2c, PSA < 20, Gleason score ≤ 7) are randomized to receive either PBT or IMRT, with targeted recruitment efforts for minority populations. A companion registry study has concurrently enrolled patients who declined randomization or whose insurance denied coverage for PBT. Patients are stratified by clinical site, age, use of rectal spacer, and fractionation schedule (conventional fractionation: 79.2 Gy in 44 fractions vs moderate hypofractionation: 70.0 Gy in 28 fractions). Participants are followed longitudinally to assess patient-reported outcomes (PROs) of bowel, urinary, and erectile function for 60 months after completion of radiotherapy (with an option for additional follow up through 10 years). Participants may also participate in correlative studies, including serial CT imaging during treatment and analyses of biopsy tissue, blood and urine specimens. The primary objective is to compare PROs of bowel function using the EPIC score at 24 months following completion of radiation. Secondary objectives are to assess treatment-related differences in urinary and erectile functions, adverse events, efficacy endpoints (biochemical control, metastasis-free survival, disease-specific survival, and overall survival), health state utilities, perceptions of care, late effects, cost-effectiveness, association between radiotherapy dose distribution and PROs, and to identify biomarkers of radiation response and toxicity. RESULTS The randomized trial has completed accrual, with 450 patients enrolled at 27 sites between June 2012 and November 2021. 20.3% of patients enrolled are non-white. Accrual on the companion registry is active, with 354 patients enrolled as of February 2023. CONCLUSION Follow-up for the primary endpoint on the randomized trial will be reached in 2024. The PARTIQoL randomized clinical trial will rigorously assess the clinical benefits of PBT relative to IMRT and results will inform decision making by patients, providers, policymakers, and payers.

Abstract
PURPOSE/OBJECTIVE(S) Testicular seminoma affects young men and is associated with very favorable prognosis. The evolution in treatment paradigm has focused on minimizing acute and especially late toxicities. Following orchiectomy, while surveillance is favored in Stage I patients, radiotherapy (RT) is a standard treatment option for de novo or relapsed stage IIA or select non-bulky stage IIB disease. Despite low doses, standard RT fields to paraaortic and pelvic lymphatics using x-rays exposes a large volume of uninvolved normal tissue/viscera to excess dose. This young patient population is especially vulnerable to risks of late RT toxicities including secondary malignancy. Proton beam therapy (PBT) has dosimetric advantage over x-ray-based RT due to lack of exit dose, and comparative dosimetric/modeling studies show significant sparing of uninvolved abdominal/pelvic organs. However, there is scant reported clinical data at this time for PBT. We review our early institutional outcomes with PBT for testicular seminoma. MATERIALS/METHODS Single institution retrospective review from a tertiary care center of patients treated with PBT from 2013-2022 for testicular seminoma. Recurrence free (RFS) and overall survival (OS) were calculated from the completion of PBT. Toxicities were graded (Gr) using CTCAE v5.0. RESULTS Four patients underwent PBT, median age 39 (range 36-47). All were Stage I at diagnosis (pT1b n = 3; pT2 n = 1) and were treated for recurrent stage II disease (IIA n = 3; IIB n = 1) at a median of 34 months from orchiectomy (range 3 - 74 months). Nodal extent included 2 with multiple paraaortic nodes, 1 with solitary paraaortic node and 1 with solitary pelvic node. PBT was delivered with pencil-beam scanning, treating paraaortic + ipsilateral pelvic fields (20 Gy in 10 fractions), then sequential boost to involved nodes (10 -16 Gy in 5-8 fractions). Typically, PA or posterior oblique fields were used to minimize dose to out-of-field abdominal/pelvic viscera. Treatment was well tolerated with minimal acute toxicities: fatigue Gr 1 (n = 3), nausea Gr 1 (n = 3). No Gr 2 or higher acute toxicities or significant late toxicities were observed. At median follow up of 30 months (range 3 - 54), no recurrences were observed, and RFS and OS were 100%. Two patients are without evidence of disease > 4 years post-treatment. CONCLUSION In this case series, PBT for retroperitoneal and pelvic metastases in Stage IIA/IIB testicular seminoma was associated with oncologic efficacy with minimal toxicity. PBT reduces unnecessary dose to abdominal/pelvic organs compared to x-ray techniques, which is advantageous in young patients who have anticipated long-term survival. This is one of the few series reporting clinical outcomes of PBT in the management of seminoma. Randomized comparisons with x-ray approaches are impractical given the relatively low volume of patients receiving RT in modern seminoma management, so it is essential to report and track longitudinal outcomes across institutions to validate this approach.

Abstract
PURPOSE/OBJECTIVE(S) Given the generally long natural history of thymic malignancies, proton beam therapy (PBT) is advocated to minimize the risk of long-term toxicities to mediastinal organs. Adverse events (AE) and long-term clinical outcomes for this population have not been well-characterized. MATERIALS/METHODS The Proton Collaborative Group registry (NCT01255748), a multi-institutional prospective database of academic and community proton centers in the US, was queried for patients with thymomas and thymic carcinomas treated with PBT. Patients with recurrent/metastatic disease, non-thymic histology, received either prior or palliative radiotherapy (dose < 40 Gy RBE) were excluded. Overall survival (OS) and local control (LC) were estimated using Kaplan-Meier methods. RESULTS A total of 97 patients were identified in the PCG registry. After applying relevant exclusion criteria, 70 patients from 12 proton centers treated from 2011-2021 were included for analysis. Median follow-up length was 16 months. Median age was 58.5 years (IQR 46-63), and 60% were female. 81.4% had a diagnosis of thymoma, and 18.6% thymic carcinoma. 59 patients underwent surgical resection. 11 were treated with definitive PBT, of which 5 received concurrent chemotherapy. Median dose was 54 Gy RBE (range 41.4 - 70 Gy RBE), median number of fractions was 30 (range 21 - 38). 73.4% received pencil beam scanning and 23% uniform scanning PBT. Treatment was overall well-tolerated: a single patient developed grade 4 pneumonitis. Grade 3 AEs were seen in 3 patients - dyspnea, anorexia, and heart failure. Highest grade toxicity experienced was grade 2 for 47.1% and grade 1 for 42.9% of patients. 3-year overall survival (OS) was 82.6% for the entire cohort. 3-year OS was 94% for resected/adjuvant cohort and 35.6% in the non-surgical/definitive cohort. 3-year local control (LC) was 91.7% for the entire cohort. By surgery/margin status, 3-year LC was 96.8% in patients with close or negative margins (a single failure in a patient with close margins), whereas 3-year LC was 55.1% for patients with positive margins/unresectable disease. CONCLUSION Thymic malignancies treated with PBT appear to have favorable outcomes, especially in the adjuvant setting, in this cohort representing the largest series of such patients.

Abstract
PURPOSE/OBJECTIVE(S) To report on outcomes, acute toxicities, and the use of dose-escalation with proton therapy (PT) in patients with rhabdomyosarcoma and Ewing sarcoma in a prospective multi-institutional registry (PCG). MATERIALS/METHODS Data on patients with primary rhabdomyosarcoma and Ewing sarcoma treated with definitive PT (defined as ≥45 Gy) were queried from the PCG registry. A similar query was performed of our institutional database with IRB approval. Overall survival rates were calculated by Kaplan-Meier. Toxicities were scored using CTCAE v4.0. RESULTS A total of 354 patients across 10 institutions (203 rhabdomyosarcoma, 151 Ewing sarcoma) met the eligibility criteria. Median age was 9 years (Interquartile Range: 5-15). Median dose was 50.4 GyRBE for rhabdomyosarcoma patients (Range: 45-66 GyRBE) and 55.8 GyRBE for Ewing sarcoma patients (Range: 45-66 GyRBE). Median follow-up was 2.4 years (Range 0.3-12.3 years). Two-year overall survival rates were 81.1% (95% CI: 73.7%-88.5%) for rhabdomyosarcoma and 79.1% (95% CI: 71.7%-86.2%) for Ewing sarcoma. The Table lists the prescription doses delivered by tumor histology; 28.1% of rhabdomyosarcoma and 21.9% of Ewing sarcoma patients, respectively, received dose-escalated radiotherapy (defined as >50.4 Gy for rhabdomyosarcoma and >55.8 Gy for Ewing sarcoma). Excluding alopecia and skin desquamation, 153 patients (43.2%) developed any acute grade 2+ non-hematologic toxicity, while 49 patients (13.8%) developed one or more grade 3 toxicities. The most common grade 3 toxicities were anorexia/weight loss (7.3%), pain (7.3%) mucositis/esophagitis (4.8%), and nausea/vomiting (3.1%). One grade 4 toxicity (esophagitis) and no deaths were reported during treatment. CONCLUSION In this multi-institutional prospective registry, 28.1% of rhabdomyosarcoma and 21.9% of Ewing sarcoma patients received dose-escalated PT, with 13.8% of patients developing grade 3 toxicities. Long-term outcomes for disease control and late toxicity and anticipated cooperative group trial results are needed to fully assess the benefits and risks of dose-escalated radiotherapy for these tumors.

Abstract
PURPOSE/OBJECTIVE(S) To characterize a proton pencil beam scanning system for ultra-high dose rate (UHDR) irradiations and validate it with FLASH preclinical experiments. MATERIALS/METHODS After modifications to the beamline to maximize the beam current at isocenter in our gantry room, we characterized the UHDR beam in terms of: 1) Size and shape of the beam spot in three configurations; pristine beam, 75 mm water-equivalent-thickness (WET) range shifter (RS), and custom-built 135 mm WET RS mounted 310 mm upstream of the aperture in the snout housing. These configurations were analyzed to determine which one achieved the highest dose rate; 2) Beam transport efficiency and beam output. We compared the signal in the monitor chambers of the proton system with a Faraday cup and plane parallel ionization chamber (PPC05, IBA dosimetry) for beam current at the cyclotron from 7.5 nA to 800 nA; 3) Dose homogeneity, beam penumbra, and dose rate for the fields to be used in preclinical irradiations. All measurements were performed at isocenter, in air or at 1 cm depth in solid water, using the highest energy (about 230 MeV), which corresponded to a nominal range of 32.9 cm in water. We modeled the UHDR beam in our treatment planning system (TPS) to optimize the dose homogeneity and lateral penumbra of the irradiation fields. We performed the preclinical experiments in single fractions of 19 Gy (RBE), 21 Gy (RBE) and 23 Gy (RBE) (RBE = 1.1), targeting the pelvis of C57BL/6 mice and using survival as the endpoint. Each arm included 6-10 mice. The proton beam was used in transmission mode, positioning the center of the mouse pelvis at isocenter, and irradiating the pelvis with a 2x6 cm^2 field. Apertures were placed at 9cm from the isocenter to sharpen the lateral penumbra. RESULTS The range measurements with a multi-layer ionization chamber were consistent within 1 mm with the nominal range. In UHDR mode, the spot size at the isocenter varied from 4.5 mm for the pristine beam to 9.2 mm for the 135 mm RS. The spot size at isocenter remained constant when the beam intensity varied from 7.5 nA to 800 nA at the cyclotron exit. By employing the configuration with the 135 mm RS and optimizing the fields in the TPS, we achieved a dose rate of 1 Gy (RBE)/s for the conventional regime and 75(RBE) Gy/s for the UHDR regime. The monitor chambers of the proton system were affected by recombination at high dose rates: we observed about 35% higher output for the same number of monitor units delivered at 800 nA vs 7.5 nA. The delivered dose was determined with the PPC05 for each field, as this detector did not show recombination effects. When preclinical irradiations were independently monitored, the delivered dose was typically within 1% of the intended value. In three independent experiments, a dose of 21 Gy (RBE) or higher was associated with an increased survival in the UHDR arm compared to the conventional arm. CONCLUSION We adapted a clinical proton system for preclinical irradiations at UHDR. Our results confirm the presence of the FLASH effect.

Abstract
PURPOSE/OBJECTIVE(S) To report on the utilization of dose-escalated radiotherapy, acute toxicities, and survival following definitive proton therapy (PT) for osteosarcoma patients in a prospective multi-institutional study. MATERIALS/METHODS Data on patients with osteosarcoma treated with definitive intent PT were queried from the Proton Collaborative Group (PCG) prospective registry. A similar query was performed on an institutional database with IRB approval. Overall survival rates were calculated by Kaplan-Meier. Toxicities were scored using CTCAE v4.0. RESULTS Forty osteosarcoma patients across 9 institutions received definitive intent PT between 2011-2021 and met the eligibility criteria. Median age was 32 years (Range: 6-86 years). Median PT dose was 66.6 GyRBE (Range: 50.4-80.0 GyRBE); 38 patients received proton therapy alone, whereas 2 received combined proton/photon therapy. Seventeen (42.5%) patients received doses ≥70 GyRBE. Median follow-up was 3.1 years (Range: 0.9-10.5 years). One-year and three-year overall survival rates were 83.5% and 59.1%, respectively, with 14 deaths due to disease. Excluding skin desquamation and alopecia, 22 patients (55.0%) developed any acute grade 2+ toxicity, and 5 patients (12.5%) developed any grade 3 toxicities. No acute grade 4-5 toxicities were reported. The most frequent grade 2+ non-skin toxicities were fatigue (37.5%), anorexia/weight loss (17.5%), mucositis/esophagitis (22.5%), pain (20.0%), and nausea/vomiting (10.0%). The most frequent grade 3 toxicities were anorexia/weight loss (5.0%), mucositis/esophagitis (5.0%), and neurologic symptoms (5.0%). CONCLUSION In this multi-institutional study, 42.5% of osteosarcoma patients treated with PT received doses between 70-80 Gy, with 12.5% experiencing any grade 3 toxicity. Long-term outcomes for disease control, late toxicity, and quality-of-life are needed to more fully assess the benefits and risks of dose-escalated radiotherapy in this radioresistant tumor. The authors plan to assess the outcomes of osteosarcoma patients treated with dose-escalated radiotherapy for unresectable or gross residual disease in future studies.

Abstract
The Southern Ocean is a major sink of atmospheric CO2, but the nature and magnitude of its variability remains uncertain and debated. Estimates based on observations suggest substantial variability that is not reproduced by process-based ocean models, with increasingly divergent estimates over the past decade. We examine potential constraints on the nature and magnitude of climate-driven variability of the Southern Ocean CO2 sink from observation-based air-sea O2 fluxes. On interannual time scales, the variability in the air-sea fluxes of CO2 and O2 estimated from observations is consistent across the two species and positively correlated with the variability simulated by ocean models. Our analysis suggests that variations in ocean ventilation related to the Southern Annular Mode are responsible for this interannual variability. On decadal time scales, the existence of significant variability in the air-sea CO2 flux estimated from observations also tends to be supported by observation-based estimates of O2 flux variability. However, the large decadal variability in air-sea CO2 flux is absent from ocean models. Our analysis suggests that issues in representing the balance between the thermal and non-thermal components of the CO2 sink and/or insufficient variability in mode water formation might contribute to the lack of decadal variability in the current generation of ocean models. This article is part of a discussion meeting issue 'Heat and carbon uptake in the Southern Ocean: the state of the art and future priorities'.

Abstract
Giant cell tumors (GCTs) of the bone are locally aggressive primary bone tumors with a benign character. Spinal involvement is rare which accounts for approximately 5% of all primary bone tumors and it is quite rare in the lumbar spine. An 11-year-old boy patient presented with pain of low back and bilateral low extremities. Lumbar CT and MRI revealed a lytic lesion of the L4 vertebra corpus. The patient earned remarkable and timely recovery with 2 surgical interventions and the use of denosumab. Surgical resection for GCTs is still preferable as the initial treatment, denosumab should be utilized after tumor resection whether based on the purpose of prevention or treatment of tumor recurrence.

Abstract
OBJECTIVE To explore the molecular mechanisms of Porphyromonas gingivalis infection-induced umbilical vein endothelial barrier dysfunction in vitro. METHODS Human umbilical vein endothelial cells (HUVECs) were cultured in vitro, and after the formation of the endothelial barrier, the cells were infected with P. gingivals at a multiplicity of infection (MOI). The transepithelial electrical resistance (TEER) of the cell barrier was measured, and FITC-dextran trans-endothelial permeability assay and bacterial translocation assay were performed to assess the endothelial barrier function. The expression levels of cell junction proteins including ZO-1, occludin and VE-cadherin in the cells were examined by qRT-PCR and Western blotting. RESULTS In freshly seeded HUVECs, TEER increased until reaching the maximum on Day 5 (94 Ωcm2), suggesting the formation of the endothelial barrier. P. gingivals infection caused an increase of the permeability of the endothelial barrier as early as 0.5 h after bacterial inoculation, and the barrier function further exacerbated with time, as shown by significantly lowered TEER, increased permeability of FITC-dextran (40 000/70 000), and increased translocation of SYTO9-E. coli cross the barrier. MTT assay suggested that P. gingivals infection did not significantly affect the proliferation of HUVECs (P>0.05), but in P. gingivalsinfected cells, the expressions of ZO-1, occludin and VE-cadherin increased significantly at 24 and 48 h after bacterial inoculation (P < 0.05). CONCLUSION P. gingivals may disrupt the endothelial barrier function by down-regulating the expressions of the cell junction proteins (ZO-1, occludin, VE-cadherin) and increasing the permeability of the endothelial barrier.

Abstract
INTRODUCTION Our previous study demonstrated that intrahepatic Th17 cells exacerbated the progression of chronic hepatitis B virus (HBV) infection. Meanwhile, we found a small group of IFN-γ and IL-17 double-positive Th17 cells (IFN-γ+IL-17+ Th17 cells) in liver tissues. This study aimed to investigate the clinical significance and properties of IFN-γ+IL-17+ Th17 cells in liver injury associated with chronic HBV infection. METHODS The frequencies of CD4+ Th cells, Tregs, and CD4+ T cells expressing specific chemokine receptors in the blood and liver tissues were detected using flow cytometry. The chemotaxis of C C chemokine receptor 5 (CCR5) and C-X-C chemokine receptor 3 (CXCR3) toward IFN-γ+IL-17+ Th17 cells and Tregs was evaluated by transwell chemotactic assay. Analyses of different variables were performed using GraphPad Prism v 5.01 and IBM SPSS Statistics 23.0. HBV-specific IFN-γ+IL-17+ Th17 cells were investigated using a cell stimulation assay with HBV antigens in vitro. RESULTS The frequencies of IFN-γ+IL-17+ Th17, Th17 cells, and Tregs in the blood were increased from normal controls to chronic hepatitis B (CHB) and acute-on-chronic liver failure (ACLF). The same trend could also be observed in CHB liver tissues compared to those in CHB blood specimens. Furthermore, the frequencies of IFN-γ+IL-17+ Th17 cells were positively associated with Th17 cells, Th17 cell-related cytokines (IL-17 and IL-6), HBV DNA load, and the levels of HBsAg, HBeAg, and ALT. The ratios of IFN-γ+IL-17+ Th17 cells to Tregs extremely decreased in ACLF blood specimens compared with those in CHB blood specimens. Additionally, CCR5 and CXCR3 were conducive to the recruitment of IFN-γ+IL-17+ Th17 cells and Tregs to liver tissue. CONCLUSIONS IFN-γ+IL-17+ Th17 cells have Th17 cell-like properties in the progression of chronic HBV infection. CCR5 and CXCR3 facilitated the recruitment of IFN-γ+IL-17+ Th17 cells and Tregs to the liver. Importantly, the ratio of IFN-γ+IL-17+ Th17 cells to Tregs might be an effective assessment indicator of the severity of liver injury.

Abstract
Objective: To evaluate the safety and feasibility of robotic-assisted thoracoscopic day surgery for pulmonary nodules. Methods: Clinical data of 523 patients with pulmonary nodule underwent robotic-assisted thoracoscopic surgery in the Department of Thoracic Surgery, Xiangya Hospital, Central South University from January 2021 to June 2022 were retrospectively analyzed, which including 223 males and 300 females, aged from 19 to 72 (54.0±11.7) years. Those patients were divided into the day surgery group (DSG) and inpatient surgery group (ISG) according to perioperative management methods. Propensity score matching (PSM) (1∶2) was performed according to the general baseline information, T stage of the tumor, surgery approach, and tumor position, and a total of 178 patients were finally included. Clinical outcomes of DSG were observed. The differences in incidence of postoperative complications, treatment-related costs and resource consumption between DSG and ISG were compared. Subgroup analysis was performed according to surgery method to evaluate the difference between DSG and ISG in lobectomy and sublobectomy. Results: In 81 cases DSG, eight patients were transferred to thoracic surgery ward, and the day surgery discharge rate was 90% (73/81). There was no statistically significant difference in incidence of postoperative complications between DSG and ISG (P=0.612). The length of stay after surgery, period of chest draining, average hospital cost, and drug cost of DSG were statistically significant lower than ISG, ((2.19±0.84) vs (4.74±1.81) days, (1.70±0.65) vs (3.45±1.85) days, (6.64±0.74) vs (8.29±0.97)×104 CNY, (0.35±0.07) vs (0.69±0.18)×104 CNY), respectively(all P<0.05). The drainage volume and VAS score at discharge in DSG and ISG group were(220.47±120.02) ml and(242.21±129.96) ml, 1.68±0.79 and 1.64±0.91, respectively, with no statistically significant difference (P>0.05). In subgroup analysis, there was no statistically significant difference in incidence of postoperative complications, drainage volume after surgery and VAS score at discharge between DSG and ISG both for lobectomy and sublobectomy patients. And the results of the length of stay after surgery, period of chest draining, and drug cost in DSG were also significantly lower than ISG (P<0.05). Conclusions: Robotic-assisted thoracoscopic day surgery for pulmonary nodule is safe and feasible, with the advantage of short length of stay after surgery, short period of chest draining, less average hospital cost and drug cost. There is no difference in incidence of postoperative complications between DSG and ISG.

Abstract
BackgroundHyperuricemia may have a protective role in diseases characterized by high levels of oxidative stress, such as osteoporosis. Previous studies have shown that hyperuricemia is associated with osteoporotic. However, this association is controversial and even yielded conflicting results.ObjectivesThis study investigated the relationship between hyperuricemia and osteoporotic among Chinese adults.MethodsThe data of cross-sectional study was collected at Guangdong Second Provincial General Hospital in Guangzhou City, China between January 2009 and December 2019. Physical examinations and laboratory measurement variables were obtained from the medical check-up system. The multivariate-adjusted logistic regression model was performed to assess the association between hyperuricemia and osteoporotic.ResultsA total of 18917 participants (11334 males and 7579 females) were included in this study, with an average age of 46.23 years (SD: 11.67) at baseline. It included 5881 cases of hyperuricemia and 1587 osteoporotic. After adjusted for the confounding factors in logistic regression analysis, we observed a negative significant association between hyperuricemia and risk of osteoporotic (odds ratio [OR],0.852, 95%CI 0.795–0.967; P <0.05). Further stratified analyses showed a negative significant association with the risk of osteoporotic in women (OR,0.787, 95%CI 0.698–0.853; P <0.05), man (OR,0.897, 95%CI 0.786–0.954; P <0.05) and old adults (OR, 0.808, 95%CI, 0.759-0.894; P <0.05). No significant differences in other groups.ConclusionOur study observed participants with hyperuricemia had significantly less osteoporosis. More high-quality research is needed to further support these findings.References[1]Zong Q, Hu Y, Zhang Q, Zhang X, Huang J, Wang T.

Abstract
BackgroundPrevious studies have observed an increasing trend in the prevalence of hyperuricemia which is linked to the physiological prerequisite for gout in recent years. However, the prevalence of hyperuricemia varies across different populations and different areas.ObjectivesThe aim of this study was to explore the prevalence of hyperuricemia and influencing factors in Chinese adults.MethodsThe analysis was a part of a cross-sectional study in Guangdong Second Provincial General Hospital in Guangzhou City, China between January 2009 and December 2019. A total of 205922 participants (21401 with hyperuricemia) were included in this study. Hyperuricemia was defined as serum uric acid ≥416.0 µmol/L (7.0 mg/dl) for men and ≥357.0 µmol/L(6.0 mg/dl) for women. We calculated the prevalence of hyperuricemia and used the multivariate-adjusted logistic regression model to identify the risk factors associated with hyperuricemia.ResultsThe overall estimated prevalence of HUA was 10.4% in China. Our study showed the prevalence of hyperuricemia in male (10.7%) was higher than that in female (9.9%) (P<0.05). The prevalence of HUA in the age group(≥75) subjects (13.3%) was higher than others. Multivariate logistic regression analysis revealed that sex (OR=1.75), age (OR=1.68), blood urea nitrogen (BUN) (OR=1.051), creatinine (Cr) (OR=1.045), high-density lipoprotein cholesterol (HDL-C) (OR=1.225), low-density lipoprotein cholesterol (LDL-C) (OR=1.466), systolic blood pressure (SBP) (OR=1.012),triglycerides (TG) (OR=1.460) and Body Mass Index (BMI) (OR=1.080) could increase the risk of hyperuricemia, while diastolic blood pressure (DBP) (OR=0.998), fasting plasma glucose (FPG) (OR=0.902) and total cholesterol (TC) (OR=0.704) were associated with a lower risk of hyperuricemia in all adults.ConclusionThe latest prevalence of hyperuricemia is high in Chinese adults and is associated with multiple factors, indicating that prevention and control strategies for hyperuricemia are needed urgently.References[1]Han B, Wang N, Chen Y, Li Q, Zhu C, Chen Y, Lu Y.

Abstract
Objective Sijunzi decoction (SJZD) was used to treat patients with colorectal cancer (CRC) as an adjuvant method. The aim of the study was to investigate the therapeutic targets and pathways of SJZD towards the tumor microenvironment of CRC via network pharmacology and the ESTIMATE algorithm. Methods The ESTIMATE algorithm was used to calculate immune and stromal scores to predict the level of infiltrating immune and stromal cells. The active targets of SJZD were searched in the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and UniProt database. The core targets were obtained by matching the differentially expressed genes in CRC tissues and the targets of SJZD. Then, GO, KEGG and validation in TCGA were carried out. Results According to the ESTIMATE algorithm and survival analysis, the median survival time of the low stromal score group was significantly higher than that of the high stromal score group (P = 0.018), while the patients showed no significant difference of OS between different immune groups (P = 0.19). A total of 929 genes were upregulated and 115 genes were downregulated between the stromal score groups (|logFC| > 2, adjusted P < 0.05); 357 genes were upregulated and 472 genes were downregulated between the immune score groups. The component-target network included 139 active components and 52 related targets. The core targets were HSPB1, SPP1, IGFBP3, and TGFB1, which were significantly associated with poor prognosis in TCGA validation. GO terms included the response to hypoxia, the extracellular space, protein binding and the TNF signaling pathway. Immunoreaction was the main enriched pathway identified by KEGG analysis. Conclusion The core genes (HSPB1, SPP1, IGFBP3 and TGFB1) affected CRC development and prognosis by regulating hypoxia, protein binding and epithelial-mesenchymal transition in the extracellular matrix.

Abstract
The NCI-MATCH was designed to characterize the efficacy of targeted therapies in histology-agnostic driver mutation-positive malignancies. Sub-protocols F and G were developed to evaluate the role of crizotinib in rare tumors that harbored either ALK or ROS1 rearrangements. Patients with malignancies that progressed following at least one prior systemic therapy were accrued to the NCI-MATCH for molecular profiling, and those with actionable ALK or ROS1 rearrangements were offered participation in sub-protocols F or G, respectively. There were five patients who enrolled on Arm F (ALK) and four patients on Arm G (ROS1). Few grade 3 or 4 toxicities were noted, including liver test abnormalities, and acute kidney injury. For sub-protocol F (ALK), the response rate was 50% (90% CI 9.8-90.2%) with one complete response among the 4 eligible patients. The median PFS was 3.8 months, and median OS was 4.3 months. For sub-protocol G (ROS1) the response rate was 25% (90% CI 1.3-75.1%). The median PFS was 4.3 months, and median OS 6.2 months. Data from 3 commercial vendors showed that the prevalence of ALK and ROS1 rearrangements in histologies other than non-small cell lung cancer and lymphoma was rare (0.1% and 0.4% respectively). We observed responses to crizotinib which met the primary endpoint for ALK fusions, albeit in a small number of patients. Despite the limited accrual, some of the patients with these oncogenic fusions can respond to crizotinib which may have a therapeutic role in this setting.

Abstract
This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). The article is a duplicate of a paper that has already been published in Medicine, 97 (2018) e11849 https://doi.org/10.1097/MD.0000000000011849. Redundant publications overweigh the relative importance of published findings and distort the academic record of the authors. One of the conditions of submission of a paper for publication is therefore that authors declare explicitly that the paper has not been previously published and is not under consideration for publication elsewhere. As such this article represents a misuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.

Abstract
OBJECTIVE To explore the incidence of enteral feeding intolerance and its risk factors in patients with malignant oral and maxillofacial tumors. METHODS We conducted a retrospective analysis of 122 patients with malignant oral and maxillofacial tumor admitted in a general hospital for enteral nutrition between March, 2018 and March, 2021. The incidence of intolerance to enteral nutrition was analyzed, and the two groups of patients with and without intolerance were compared for age, gender, height, weight, pathological staging, types of enteral nutrition preparations, clinical treatment (physical hypothermia and nasal delivery), drug usage (sedatives, vasoactive drugs, acid suppressant, potassium preparation, antibiotics and hormones) and biochemical parameters (serum total protein, serum albumin, blood glucose and serum potassium concentration). Logistic regression analysis was used to analyze the influencing factors of enteral nutritional feeding intolerance in patients. RESULTS Of the 122 patients, 52 had enteral feeding intolerance with an incidence rate of 42.6%. Logistic regression analysis showed that potassium preparation (OR=4.125, P=0.027, 95%CI: 1.178-14.444), sedatives (OR=4.125, P=0.000, 95%CI: 2.007-11.765) and hypoproteinemia (OR=3.557, P=0.010, 95%CI: 1.351-9.366) were independent risk factors of feeding intolerance in patients with malignant oral and maxillofacial tumors, while adding dietary fiber was a protective factor (OR= 0.108, P=0.015, 95%CI: 0.018-0.643). CONCLUSION The incidence of enteral feeding intolerance is high in patients with malignant oral and maxillofacial tumors. Enteral nutrition preparations with dietary fiber are recommended for these patients. The patients with potassium preparations, sedatives and hypoproteinemia should be closely monitored for enteral feeding intolerance, and timely intervention should be administered to reduce its incidence.

Abstract
OBJECTIVE Dysregulated lipid metabolism has been reported in the progression of hepatocellular carcinoma (HCC). In the present study, we investigated the molecular characteristics of lipid-metabolism-related genes (IMRGs) as prognostic markers for HCC. MATERIALS AND METHODS Multi-dimensional bioinformatics analyses were performed to comprehensively analyze IMRGs, and to construct prognostic prediction signatures. RESULTS Data of 770 HCC patients and their corresponding 776 IMRGs were downloaded from three databases. Patients were classified into 2 molecular clusters that were associated with overall survival, clinical characteristics, and immune cells. The biological functions of the IMRGs differentially expressed between the 2 clusters were associated with tumor-related metabolic pathways. A 6 IMRG signature (6-IS), consisting of FMO3, SLC11A1, RNF10, KCNH2, ME1, and ZIC2, was established as an independent prognostic factor for HCC. The performance of the signature of 6-IS prognostic was verified in a validation set and compared to an external data set. It was revealed that the 6-IS could effectively predict the prognosis of patients with HCC. CONCLUSIONS This study provides new insights into the role of IMRGs in the pathogenesis of HCC, and presents a novel signature (6-IS) to predict the prognosis of HCC.

Abstract
Objective: To explore the clinical features of poly ADP-ribose polymerase (PARP) inhibitor-related anemia in advanced and relapsed epithelial ovarian cancer (EOC). Methods: Patients diagnosed with advanced or relapsed EOC and treated with PARP inhibitor at National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between January 2015 to October 2020 were accrued. The data included PARP inhibitors, treatment details, and lab tests before treatment and during treatment were collected and the clinical characteristics of PARP inhibitor-related anemia were analyzed. Results: (1) A total of 98 patients with a median age of 56.5 years old (30-82 years old) were enrolled in this study. All patients were treated with PARP inhibitor (65 cases of olaparib, 17 cases of niraparib, and 16 cases of fluzoparib). The median treatment duration was 37.5 weeks (4-119 weeks). (2) The anemia rate was 40% (39/98), including 5% (5/98) of grade Ⅰ, 14% (14/98) of grade Ⅱ, 11% (11/98) of grade Ⅲ, and 9% (9/98) of grade Ⅳ. Fourteen patients with pre-treatment grade Ⅰ anemia had a higher rate of anemia events than the 80 patients without pre-treatment anemia, 7/14 vs 35% (28/80; χ2=4.281, P=0.039). (3) The median anemia occurrence time was 7.0 weeks (1-52 weeks), including 41% (16/39) of anemia cases occurred in 1-4 weeks, 26% (10/39) occurred in 5-8 weeks, 13% (5/39) occurred in 9-12 weeks, 3% (1/39) occurred in 13-16 weeks, 10% (4/39) occurred in 17-20 weeks, 8% (3/39) occurred ≥21 weeks. At the time of the lowest hemoglobulin tested, the median value of mean corpuscular volume (MCV) was 106 fl,which was higher than the up limit of normal range (100 fl), 74% (29/39) of anemia patients had an elevated MCV level; the median value of mean corpuscular hemoglobin (MCH) was 36 pg, 54% (21/39) of anemia patients had an elevated MCH level; the median value of mean corpuscular hemoglobin concentration (MCHC) was 320 g/L, 69% (27/39) of anemia patients had a higher MCHC level; 92% (36/39) of anemia patients had a normal level of serum iron; 79% (31/39) of anemia patients had a normal level of transferrin. 74% (29/39) of the anemia patients were macrocytic orthochromatic anemia. (4) Among the 39 patients with anemia, 20 patients (51%, 20/39) withhold the treatment of PARP inhibitor due to grade Ⅲ or Ⅳ anemia, including 10 patients (50%, 10/20) who resumed the PARP inhibitor treatment by suppling iron, folate, and vitamin B12. The median stopping time of PARP inhibitor was 5.5 weeks (2-10 weeks), while the other 10 patients terminated the PARP inhibitor treatment for not recovering from severe anemia. Conclusions: One of the common adverse effects of PARP inhibitors is anemia, which mostly happened in the first 3 months of treatment. In the treatment of EOC, PARP inhibitor-related anemia mainly manifest as macrocytic orthochromatic anemia, and most patients with normal serum iron and transferrin.

Abstract
Background Psoriasis is a chronic inflammatory skin disease requiring prolonged treatment. New biologic therapies require long‐term evaluation to assess the durability of their efficacy and safety profiles over time. Objectives To evaluate the long‐term efficacy and safety of risankizumab (RZB) for the treatment of psoriasis. Methods LIMMitless is an ongoing, phase III, open‐label extension study evaluating the long‐term efficacy and safety of RZB in adults with moderate‐to‐severe plaque psoriasis following multiple phase II/III studies. This analysis assessed efficacy through 172 weeks of continuous RZB treatment by examining the proportion of patients achieving ≥ 90% or 100% improvement in Psoriasis Area and Severity Index (PASI 90 and PASI 100), static Physician’s Global Assessment of clear or almost clear (sPGA 0/1) and Dermatology Life Quality Index of no effect on quality of life (DLQI 0/1). Safety was assessed by recording adverse events (AEs) through the data cutoff date. The study is registered at ClinicalTrials.gov (identifier: NCT03047395). Results Of 955 patients randomized to RZB 150 mg in the base studies, 897 patients continued into LIMMitless; 799 patients were still receiving treatment in LIMMitless at the time of data cutoff for this analysis. After 172 weeks of continuous RZB treatment, 85·5% of patients achieved PASI 90, 54·4% achieved PASI 100, 85·2% achieved sPGA 0/1, and 78·4% achieved DLQI 0/1 using modified nonresponder imputation. Rates of AEs leading to discontinuation and AEs of safety interest were low with long‐term treatment and comparable with those identified in the base studies. Conclusions Overall, long‐term continuous RZB was well tolerated and showed high and durable efficacy over 172 weeks.
What is already known about this topic?
Risankizumab is a humanized immunoglobulin G1 monoclonal antibody that specifically inhibits interleukin‐23 by binding to its p19 subunit. In multiple phase II/III clinical trials in adults with moderate‐to‐severe psoriasis, risankizumab has displayed superior efficacy vs. placebo or other psoriasis treatments for up to 52 weeks.
What does this study add?
LIMMitless is an ongoing phase III open‐label extension study designed to evaluate the long‐term safety and efficacy of risankizumab treatment for up to 5 years of continuous use. The results from this interim analysis demonstrate that risankizumab offers sustained efficacy after more than 3 years of continuous use, with no new safety signals identified.

Abstract
Background:Hyperuricemia has been reported to be significantly associated with risk of obesity. However, previous studies on the association between serum uric acid (SUA) and body mass index (BMI) yielded conflicting results.Objectives:The present study examined the relationship between SUA and obesity among Chinese adults.Methods:Data were collected at Guangdong Second Provincial General Hospital in Guangzhou City, China between January 2010 and December 2018. Participants with ≥2 medical checkup times were included in our analyses. Logistic regression model (LRM) was performed for data at baseline. For all participants, generalized estimation equation (GEE) model was used to assess the association between SUA and obesity, where the data were repeatedly measured over the nine-year study period. We calculated the cut-off values for SUA of obesity using the receiver operating characteristic curves (ROC) technique.Results:A total of 15,959 participants (10,023 males and 5,936females) were included in this study, with an average age of 37.38 years (SD: 13.27) and average SUA of 367.05 μmol/L (SD: 97.97) at baseline, respectively. Finally, 1078 participants developed obesity over the 9-year period. The prevalence of obesity was approximately 14.2% for high SUA level. In logistic regression analysis at baseline, we observed a positive association between SUA and risk of obesity: OR=1.84 (95% CI: 1.77,1.90) for per-SD increase in SUA. Considering repeated measures over 9-year for all participants in the GEE model, the per-SD OR was 1.85 (95% CI:1.77,1.91) for SUA and the increased risk of obesity were greater for male (OR=1.45) and elderly participants (OR=1.01). The SUA cutoff points for risk of obesity using ROC curves were approximately consistent with the international standard.Conclusion:Our study observed higher SUA level was associated with increased risk of obesity. More high-quality research is needed to further support these findings.References:[1]Nagahama S, Kashino I, Hu H, Nanri A, Kurotani K, Kuwahara K et al.

Abstract
PURPOSE The aim of this study was to evaluate the efficacy of liposome-paclitaxel and carboplatin combination chemoradiotherapy for patients with locally advanced esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS Seventy-nine consecutive patients treated with liposome-paclitaxel based concurrent chemoradiotherapy between January 2015 and December 2019 at Cancer hospital of the University of Chinese Academy of Sciences (Zhejiang cancer hospital) were enrolled in this study. The overall response, toxicities, progression-free survival and overall survival were analyzed with SPSS software. RESULTS A total of 302 cycles of weekly chemotherapy were delivered, with a median 4 courses. After concurrent chemoradiotherapy (CCRT), the efficacy was classified as CR in 4 cases (5.1%), PR in 22 cases (28.2%) and SD in 51 cases (65.4%). The median PFS and OS time were 18.2 months and 23.4 months. The 3-year PFS and OS rates were 45.1% and 43.6%, respectively. CONCLUSIONS Liposome-paclitaxel and carboplatin concurrent with radiotherapy is a safe and effective modality for locally advanced ESCC. Further clinical investigation are warranted to evaluate the efficacy of this regimen.

Abstract
BACKGROUND The effectiveness and cost-effectiveness of biologic therapies for psoriasis are significantly compromised by variable treatment responses. Thus, more precise management of psoriasis is needed. OBJECTIVES To identify subgroups of patients with psoriasis treated with biologic therapies, based on changes in their disease activity over time, that may better inform patient management. METHODS We applied latent class mixed modelling to identify trajectory-based patient subgroups from longitudinal, routine clinical data on disease severity, as measured by the Psoriasis Area and Severity Index (PASI), from 3546 patients in the British Association of Dermatologists Biologics and Immunomodulators Register, as well as in an independent cohort of 2889 patients pooled across four clinical trials. RESULTS We discovered four discrete classes of global response trajectories, each characterized in terms of time to response, size of effect and relapse. Each class was associated with differing clinical characteristics, e.g. body mass index, baseline PASI and prevalence of different manifestations. The results were verified in a second cohort of clinical trial participants, where similar trajectories following the initiation of biologic therapy were identified. Further, we found differential associations of the genetic marker HLA-C*06:02 between our registry-identified trajectories. CONCLUSIONS These subgroups, defined by change in disease over time, may be indicative of distinct endotypes driven by different biological mechanisms and may help inform the management of patients with psoriasis. Future work will aim to further delineate these mechanisms by extensively characterizing the subgroups with additional molecular and pharmacological data.

Abstract
Objective: To investigate the spectrum and antimicrobial resistance of major pathogens causing nosocomial infections in China, 2018. Methods: Non-duplicated nosocomial cases as well as pathogens causing bloodstream infections (BSI), hospital-acquired pneumonia (HAP) and intra-abdominal infections (IAI) from 11 teaching hospitals across China were collected. The minimum inhibitory concentrations (MICs) of clinically significant strains were determined by agar dilution method or broth microdilution method. The Clinical and Laboratory Standards Institute (CLSI) M100-S29 criteria were used for interpretation, and the WHONET-5.6 software was used in data analysis. Results: A total of 1 590 cases were collected, including 831 cases from BSI, 450 cases from HAP and 309 cases from IAI. The most prevalent pathogens causing BSI were Escherichia coli (29.2%, 243/831), Klebsiella pneumoniae (16.2%, 135/831) and Staphylococcus aureus (10.1%, 84/831); the most prevalent pathogens causing IAI were E. coli (26.2%, 81/309), Enterococcus faecium (15.5%, 48/309) and K. pneumoniae (13.3%, 41/309); while Acinetobacter baumanii (24.7%, 111/450), Pseudomonas aeruginosa (20.7%, 93/450) and K. pneumoniae (16.2%, 73/450) were dominated in HAP. All S. aureus were susceptible to tigecycline, linezolid, daptomycin and glycopeptides; 77.8% (105/135) of S. aureus strains were susceptible to ceftaroline. Methicillin-resistant S. aureus (MRSA) accounted for 29.6% (40/135) of all the S. aureus, and was lower than the accounted rate of methicillin-resistant coagulase-negative Staphylococcus (MRCNS) (83.7%, 41/49). One E. faecium strain (1.1%, 1/95) resistant to vacomycin and teicoplanin and one E. faecalis strain (2.3%, 1/43) resistant to linezolid was found. The prevalence of extended-spectrum β-lactamase (ESBL) was 56.1% (193/344) in E. coli and 22.1% (55/249) in K. pneumonia; the rate of carbapenem resistant E. coli and K. pneumonia was 4.1% (14/344) and 22.9% (57/249), respectively; the percentage of ceftazidime/avibactam resistant E. coli and K. pneumonia was 2.3% (8/344) and 2.0% (5/249), respectively; the percentage of colistin resistant E. coli and K. pneumonia was 1.5% (5/344) and 7.6% (19/249), respectively; no E. coli and K. pneumonia strains were found resistant to tigecycline. The rate of carbapenem resistant A. baumanii and P. aeruginosa were 78.9% (146/185) and 36.7% (66/180), respectively. A. baumanii showed low susceptibility to the antimicrobial agents except colistin (99.5%, 184/185) and tigecycline (91.4%, 169/185). Colistin, amikacin and ceftazidime/avibactam demonstrated high antibacterial activity against P. aeruginosa with susceptility rate of 100% (180/180), 93.3% (168/180) and 85.6% (154/180), respectively. Conclusions: Nosocomial Gram-negative pathogens show high susceptibilities to tigecycline, colistin and ceftazidime/avibactam in vitro. Antimicrobial resistance in A. baumannii is a serious problem. The prevalence of carbapenem-resistant Enterobacteriaceae has increased, which should be monitored continuously in China.

Abstract
BACKGROUND & AIM Although serum fibroblast growth factor 21 (FGF21) levels are associated with liver fat content in non-alcoholic liver fat disease (NAFLD), the precise nature of the association remains undetermined. Therefore, this study aimed to explore the potential dose-response relationship between FGF21 and liver fat content in NAFLD. METHODS For this exploratory study from a randomized trial, 220 NAFLD patients with central obesity were recruited via community-based screening and randomly assigned to either control, moderate or vigorous-moderate exercise groups for 12 months. After this exercise intervention, patients were followed-up for a further 12 months. Serum FGF21 levels were measured by ELISA. Intrahepatic triglyceride (IHTG) content was determined by proton magnetic resonance spectroscopy. RESULTS Of the 220 patients, 149 (67.7%) were female; mean age was 53.9 ± 7.1 years and mean BMI was 28.0 ± 2.9 kg/m2 for all patients. Baseline IHGT increased gradually (P = 0.029 for trend) according to baseline serum FGF21 quartiles 1, 2, 3 and 4 (212.3, 358.9, 538.7 and 793.5 pg/mL, respectively). On grouping the distribution of serum FGF21 level changes into quartiles at month 12, the relative IHTG loss increased as serum FGF21 levels were reduced (P = 0.004 for trend). A similar trend was observed at month 24 (P = 0.006 for trend). Multivariate linear regression analysis revealed that changes in serum FGF21 levels were independently associated with changes in IHTG at both month 12 [β (SE), 0.136 (0.118); P = 0.048] and month 24 [β (SE), 0.152 (0.139); P = 0.041]. Using restricted cubic spline regression, changes in serum FGF21 were strongly and positively associated with their corresponding relative IHTG loss at both month 12 and follow-up (Poverall = 0.017, Pnon-linear = 0.044 and Poverall = 0.020, Pnon-linear = 0.361, respectively, for dose-response). CONCLUSION Serum FGF21 is strongly associated with liver fat content in a dose-response manner in centrally obese NAFLD patients. These findings support the use of serum FGF21 as a biomarker of liver fat content in NAFLD.

Abstract
AIMS To search for a set of reference genes for reliable gene expression analysis in the globally important marine coccolithophore Emiliania huxleyi-virus model system. METHODS AND RESULTS Fifteen housekeeping genes (CDKA, CYP15, EFG3, POLAI, RPL30, RPL13, SAMS, COX1, GPB1-2, HSP90, TUA, TUB, UBA1, CAM3 and GAPDH) were evaluated for their stability as potential reference genes for qRT-PCR using ΔCt, geNorm, NormFinder, Bestkeeper and RefFinder software. CDKA, TUA and TUB genes were tested as loading controls for Western blot in the same sample panel. Additionally, target genes associated with cell apoptosis, that is metacaspase genes, were applied to validate the selection of reference genes. The analysis results demonstrated that putative housekeeping genes exhibited significant variations in both mRNA and protein content during virus infection. After a comprehensive analysis with all the algorithms, CDKA and GAPDH were recommended as the most stable reference genes for E huxleyi virus (EhV) infection treatments. For Western blot, significant variation was seen for TUA and TUB, whereas CDKA was stably expressed, consistent with the results of qRT-PCR. CONCLUSIONS CDKA and GAPDH are the best choice for gene and protein expression analysis than the other candidate reference genes under EhV infection conditions. SIGNIFICANCE AND IMPACT OF THE STUDY The stable internal control genes identified in this work will help to improve the accuracy and reliability of gene expression analysis and gain insight into complex E. huxleyi-EhV interaction regulatory networks.
