Abstract
Background & Aims A high human cytomegalovirus (HCMV) infection rate accompanied by an increased level of bile duct damage is observed in the perinatal period. The possible mechanism was investigated. Methods A total of 1,120 HCMV-positive and 9,297 HCMV-negative children were recruited, and depending on age, their liver biochemistry profile was compared. Fetal and infant biliary epithelial cells (F-BECs and I-BECs, respectively) were infected with HCMV, and the differences in cells were revealed by proteomic analysis. Protein-protein interactions were examined by coimmunoprecipitation and mass spectrometry analyses. A murine cytomegalovirus (MCMV) infection model was established to assess treatment effects. Results Perinatal HCMV infection significantly increased the level of bile duct damage. Neonatal BALB/c mice inoculated with MCMV showed obvious inflammation in the portal area with an abnormal bile duct structure. Proteomics analysis showed higher CD14 expression in F-BECs than in I-BECs. CD14 siRNA administration hindered HCMV infection, and CD14-knockout mice showed lower MCMV-induced bile duct damage. HCMV infection upregulated CD55 and poly ADP-ribose polymerase-1 (PARP-1) expression in F-BECs. Coimmunoprecipitation and mass spectrometry analyses revealed formation of the CD14-CD55 complex. siRNA-mediated inhibition of CD55 expression reduced sCD14-promoted HCMV replication in F-BECs. In MCMV-infected mice, anti-mouse CD14 antibody and PARP-1 inhibitor treatment diminished cell death, ameliorated bile duct damage, and reduced mortality. Conclusions CD14 facilitates perinatal HCMV infection in BECs via CD55, and PARP-1-mediated cell death was detected in perinatal cytomegalovirus-infected BECs. These results provide new insight into the treatment of perinatal HCMV infection with bile duct damage. Impact and implications Perinatal human cytomegalovirus (HCMV) infection is associated with bile duct damage, but the underlying mechanism is still unknown. We discovered that CD14 expression is increased in biliary epithelial cells during perinatal HCMV infection and facilitates viral entry through CD55. We also detected PARP-1-mediated cell death in perinatal HCMV-infected biliary epithelial cells. We showed that blocking CD14 or inhibiting PARP-1 reduced bile duct damage and mortality in a mouse model of murine cytomegalovirus infection. Our findings provide a new insight into therapeutic strategies for perinatal HCMV infection.

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
Periampullary neoplasm is rare in pediatric patients and has constituted a strict indication for pancreatoduodenectomy (PD), which is a procedure sporadically reported in the literature among children. Robotic PD has been routinely performed for periampullary neoplasm in periampullary neoplasm, but only a few cases in pediatric patients have been reported. Here, we report the case of a 3-year-old patient with periampullary rhabdomyosarcoma treated with robotic pylorus-preserving PD and share our experience with this procedure in pediatric patients. A 3-year-old patient presented with obstructive jaundice and a mass in the pancreatic head revealed by imaging. A laparoscopic biopsy was performed. Jaundice progressed with abdominal pain and elevated alpha-amylase leading to urgent robotic exploration in which a periampullary neoplasm was revealed and pathologically diagnosed as rhabdomyosarcoma by frozen section examination. After pylorus-preserving PD, we performed a conventional jejunal loop following a child reconstruction, including an end-to-end pancreaticojejunostomy, followed by end-to-side hepaticojejunostomy and duodenojejunostomy. Delayed gastric emptying (DGE) presented with increasing drain from the nasogastric tube (NGT) a week after the surgery and improved spontaneously within 10 days. In a 13-month follow-up until the present, our case patient recovered well without potentially fatal complications, such as pancreatic fistula. Robotic PD in pediatric patients was safe and effective without intra- or postoperative complications.

Abstract
The sympathetic nervous system (SNS) is a crucial branch of the autonomic nervous system (ANS) that is responsible for regulating visceral function and various physiological processes. Dysfunction of the SNS can lead to various diseases, such as hypertension and metabolic disorders. However, obtaining sympathetic neurons from human tissues for research is challenging. The current research aimed at recapitulating the process of human sympathetic neuron development and achieved the successful establishment of a stepwise, highly efficient in vitro differentiation protocol. This protocol facilitated the generation of functional and mature sympathetic neurons from human pluripotent stem cells (hPSCs) using a chemical-defined induction medium. Initially, each differentiation stage was refined to derive sympathoadrenal progenitors (SAPs) from hPSCs through neural epithelial cells (NECs) and trunk neural crest stem cells (NCSCs). hPSC-derived SAPs could be expanded in vitro for at least 12 passages while maintaining the expression of SAP-specific transcription factors and neuronal differentiation potency. SAPs readily generated functional sympathetic neurons (SymNs) when cultured in the neuronal maturation medium for 3-4 weeks. These SymNs expressed sympathetic markers, exhibited electrophysiological properties, and secreted sympathetic neurotransmitters. More importantly, we further demonstrated that hPSC-derived SymNs can efficiently regulate the adipogenesis of human adipose-derived stem cells (ADSCs) and lipid metabolism in vitro. In conclusion, our study provided a simple and robust protocol for generating functional sympathetic neurons from hPSCs, which may be an invaluable tool in unraveling the mechanisms of SNS-related diseases.

Abstract
BACKGROUND Biliary atresia (BA) is a severe neonatal disease with progressive intra- and extra-hepatic bile ducts inflammation and hepatic fibrosis. Characterization of gut microbiome profiles in infants with biliary atresia can provide valuable information and potential disease biomarkers. Our study aims to explore the relationship between gut microbiota and biliary atresia. METHODS 16 S ribosomal RNA (rRNA) gene sequencing was carried out to identify the differences in composition and diversity of gut microbiota between infants with BA and healthy subjects. A total of 31 infants with biliary atresia and 20 healthy subjects were recruited. RESULTS The composition of gut microbiota in BA group was significantly different with the normal control group (P < 0.05) and the abundance ratio of Klebsiella/Bifidobacterium showed great potential for identification of BA (P < 0.01). In addition, the differential bacterial taxa were involved in lipid and vitamins metabolism. CONCLUSION Our results could provide potential non-invasive biomarker for identification of biliary atresia and contribute to the treatment in terms of ameliorating microbiota dysbiosis.

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
Background & Aims Our previous study indicated that CD177+ neutrophil activation has a vital role in the pathogenesis of biliary atresia (BA), which is partially ameliorated by N-acetylcysteine (NAC) treatment. Here, we evaluated the clinical efficacy of NAC treatment and profiled liver-resident immune cells via single cell RNA-sequencing (scRNA-seq) analysis to provide a comprehensive immune landscape of NAC-derived immune regulation. Methods A pilot clinical study was conducted to evaluate the potential effects of intravenous NAC treatment on infants with BA, and a 3-month follow-up was carried out to assess treatment efficacy. scRNA-seq analysis of liver CD45+ immune cells in the control (n = 4), BA (n = 6), and BA + NAC (n = 6) groups was performed and the effects on innate cells, including neutrophil and monocyte-macrophage subsets, and lymphoid cells were evaluated. Results Intravenous NAC treatment demonstrated beneficial efficacy for infants with BA by improving bilirubin metabolism and bile acid flow. Two hepatic neutrophil subsets of innate cells were identified by scRNA-seq analysis. NAC treatment suppressed oxidative phosphorylation and reactive oxygen species production in immature neutrophils, which were transcriptionally and functionally similar to CD177+ neutrophils. We also observed the suppression of hepatic monocyte-mediated inflammation, decreased levels of oxidative phosphorylation, and M1 polarisation in Kupffer-like macrophages by NAC. In lymphoid cells, enhancement of humoral immune responses and attenuation of cellular immune responses were observed after NAC treatment. Moreover, cell-cell interaction analysis showed that innate/adaptive proinflammatory responses were downregulated by NAC. Conclusions Our clinical and scRNA-seq data demonstrated that intravenous NAC treatment partially reversed liver immune dysfunction, alleviated the proinflammatory responses in BA by targeting innate cells, and exhibited beneficial clinical efficacy. Impact and implications BA is a serious liver disease that affects newborns and has no effective drug treatment. In this study, scRNA-seq showed that NAC treatment can partially reverse the immune dysfunction of neutrophil extracellular trap-releasing CD177+ neutrophils and Kupffer cells, and lower the inflammatory responses of other innate immune cells in BA. In consequence, intravenous NAC treatment improved the clinical outcomes of patients with BA in term of bilirubin metabolism.

Abstract
Background Annular pancreas is a rare congenital disorder that requires surgical management once diagnosed. Diamond-shaped and side-to-side duodenoduodenostomy are both popular worldwide nowadays in the surgical management of annular pancreas. Here we present our experience with laparoscopic management of annular pancreas in the last 5 years and compare the clinical results of the diamond-shaped versus side-to-side anastomotic techniques. Methods Fifty-two patients diagnosed with annular pancreas who underwent duodenoduodenostomy at our medical center between January 2016 and April 2021 were included in the study. Forty-four patients underwent laparoscopic diamond-shaped duodenoduodenostomy (DS group) and eight underwent laparoscopic side-to-side duodenoduodenostomy (STS group). Clinical data, including surgical indices and early outcomes after surgery, with at least 19 months of follow-up, were collected and analyzed. Results Of the 52 patients, 61.5% were prenatally diagnosed, and vomiting was the most common clinical manifestation after birth. The operative time and bleeding volume were 187.5 [interquartile range (IQR), 150-228)] min and 2 (IQR, 2-5) mL in the DS group, compared to 175 (IQR, 155-270) min and 2 (IQR, 2-4.25) mL in the STS group (P=0.89 and 0.32 respectively). The mean time from surgery to initial oral feeding and full oral feeding was 6 (IQR, 4-10) and 12 (IQR, 10-15) days in the DS group, compared to 8 (IQR, 4.75-11.25) and 14.5 (IQR, 13-16.75) days in the STS group (P=0.61 and 0.46 respectively). The mean hospital stay was 16 (IQR, 14-19) and 20 (IQR, 17.75-26) days in the DS and STS groups respectively (P=0.13). No severe complications such as anastomotic leakage, anastomotic stenosis, reoperation or unsuspected rehospitalization were noted in either group. Feeding intolerance was revealed in six cases in the DS group and two cases in the STS group, and there was no significant difference between the two groups (P=0.50). Conclusions Both laparoscopic diamond-shaped and side-to-side techniques showed good clinical results in treating annular pancreas. The surgical technique, trans-anastomotic tube and early feeding are not likely to increase the risk of postoperative feeding intolerance.

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
Objectives To explore the outcomes and related factors in children without cholangitis after Kasai portoenterostomy (KPE). Methods We retrospectively analyzed the data of infants with type III BA who underwent KPE from June 2016 to December 2021. We compared and analyzed the difference in native liver survival (NLS) rates in different types of cholangitis. We also investigated the relationship between the absence of cholangitis and the effect of early bile drainage (EBD) as well as the related factors affecting EBD efficacy. Results A total of 145 children were included in this study. Among these children, 82 (56.6%, 82/145) had cholangitis, including 40 (48.8%, 40/82) with early cholangitis and 33 (40.2%, 33/82) with recurrent cholangitis. The median follow-up period was 29 months (range, 2-75 months). The NLS rates were 67.6%, 51.7%, 45.5% and 43.4% at 6 months, 1 year, 2 years and 5 years following KPE, while the NLS rates for infants without cholangitis after KPE were 68.3%, 50.8%, 46.0% and 46.0%, respectively. Higher gamma-glutamyl transferase (γ- GT) and total bile acid (TBA) before KPE were risk factors for cholangitis (P < 0.05). The NLS rate in recurrent cholangitis was significantly lower than that in occasional cholangitis (P < 0.01). Compared with the EBD-poor group, the NLS rate in the EBD-good group of infants was significantly increased (P < 0.001). EBD was significantly correlated with the occurrence and frequency of cholangitis (P < 0.05). Conclusions Recurrent cholangitis was an important factor affecting NLS. For children without cholangitis after KPE, early bile drainage was better, and the NLS was longer.

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.

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
BACKGROUND/PURPOSE There is currently no consensus on the timing of operative correction for patients with a prenatal diagnosis of choledochal cyst (CDC). This study aims to retrospectively analyze patients with prenatally diagnosed CDCs to identify the optimal timing of operative correction and the importance of cyst size as a predictor of the appearance of symptoms related to the CDC. METHODS We reviewed 125 patients with a prenatal diagnosis of CDC who were admitted to Guangzhou Women and Children's Medical Center from July 2015 to July 2020. After dividing the patients into a symptomatic group (n = 37) and an asymptomatic group (n = 88), according to whether they had any clinical symptoms at the time of their operation, we compared their clinical data and postoperative outcomes. The asymptomatic group was divided into a <1 month group; a ≥1 month and <4 months group; and a ≥4 months group according to their postnatal age at operation; postoperative complications of the three groups were then compared. We were also interested in the effect of cyst size (width and length) for predicting the development of symptoms related to the CDC. RESULTS The time of onset of symptoms after birth was mainly concentrated in the first 3 months (48.6%). The median width and length of cysts measured by preoperative magnetic resonance cholangiopancreatography in the symptomatic group were greater than those in the asymptomatic group (43 mm vs 28 mm and 71 mm vs 45 mm, respectively; P < .05). The serum levels of the liver-related enzymes ALT, AST, and GGT, and the serum level of DBIL, were greater in the symptomatic group than in the asymptomatic group (P < .05). The operative time, intraoperative blood loss, and duration of postoperative hospital stay in the symptomatic group were greater than those in the asymptomatic group (P < .05). In the asymptomatic group, there were no statistically significant differences in the surgical data and postoperative complications between the <1 month group, the ≥1 month and <4 months group, and the ≥4 months group. The area under the receiver operating characteristic curve (AUROC) of the length of the cyst in predicting symptoms was 0.747, the best cut-off point was 5.2 cm, and the sensitivity and specificity were 78% and 70%, respectively. The AUROC of the width of the cyst was 0.704, the best cut-off point was 4.1 cm, and the sensitivity and specificity were 68% and 75%, respectively. CONCLUSION We maintain that it is advantageous to receive surgical treatment in the asymptomatic period for patients with a prenatally diagnosed CDC. A cyst size of length >5.2 cm and width >4.1 cm suggested that clinical symptoms might appear, and that surgery should be carried out as soon as possible, even in the neonatal period.

Abstract
BACKGROUND & AIMS We have previously reported on the potential pathogenic role of neutrophils in biliary atresia (BA). Herein, we aimed to delineate the role of CD177+ neutrophils in the pathogenesis of BA. METHODS Immune cells from the livers of mice with rhesus rotavirus-induced BA were analysed. Single-cell RNA-sequencing was performed to specifically analyse Gr-1+ (Ly6C/Ly6G+) cells in the liver. Gene expression profiles of CD177+ cells were analysed using the Smart-Seq RNA-sequencing method, and the pathogenesis of BA was examined in Cd177-/- mice. Neutrophil extracellular trap (NET) inhibitors were used to determine the role of CD177+ cell-derived NETs in BA-associated bile duct damage, and a pilot clinical study evaluated the potential effects of N-acetylcysteine on NET release in BA. RESULTS Increased levels of Gr-1+ cells were observed in the livers of mice with rhesus rotavirus-induced BA. RNA-sequencing analysis revealed that CD177+ cells were the main population of Gr-1+ cells and expressed elevated levels of both interferon-stimulated and neutrophil degranulation genes. Cd177-/- BALB/c mice exhibited delayed disease onset and reduced morbidity and mortality. High numbers of mitochondria were detected in CD177+ cells derived from mice with BA; these cells were associated with increased levels of reactive oxygen species and increased NET formation, which induced the apoptosis of biliary epithelial cells in cocultures. In a pilot clinical study, the administration of N-acetylcysteine to patients with BA reduced CD177+ cell numbers and reactive oxygen species levels, indicating a potential beneficial effect. CONCLUSIONS Our data indicate that CD177+ cells play an important role in the initiation of BA pathogenesis via NET formation. CLINICAL TRIAL REGISTRATION The pilot study of N-acetylcysteine treatment in patients with BA was registered on the Chinese Clinical Trial Registry (ChiCTR2000040505). LAY SUMMARY Neutrophils (a type of innate immune cell, i.e. an immune cell that doesn't target a specific antigen) are thought to play a role in the development of biliary atresia (a rare but potentially lethal condition of the bile ducts that occurs in infants). Herein, we found that neutrophils expressing a particular protein (CD177) played an important role in bile duct damage by releasing a special structure (NET) that can trap and kill pathogens but that can also cause severe tissue damage. A pilot study in patients with biliary atresia showed that inhibiting NETs could have a beneficial effect.

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
BACKGROUND Kaposiform hemangioendothelioma (KHE) is a rare locally aggressive vascular tumor. The pancreas is not a common site of KHE, especially in pediatric patients. Given that no guidelines are available for the treatment of KHE, management is currently based on expert opinions and clinical experiences. Here, we report a case of pancreatic KHE with obstructive jaundice, which was treated successfully with oral sirolimus instead of radical surgery. Additionally, a literature review on pancreatic KHE was performed to summarize prior clinical experiences and the available treatments. CASE DESCRIPTION A 10-month-old Chinese male infant presented with obstructive jaundice without any signs of fever, abdominal pain, or distention. A detailed consultation revealed an uneventful history. The obstructive jaundice worsened significantly during 3 weeks of conservative therapy. A pancreatic mass was identified via radiological evidence, and a laparoscopic biopsy of the tumor was performed, which confirmed the diagnosis of pancreatic KHE based on histological findings. Oral sirolimus 0.8 mg/m2 twice daily was administered at a steady serum concentration of 5-15 ng/mL, which led to a shrinkage in tumor size and resolution of jaundice. The patient showed no evidence of recurrence after 1 year of follow-up and is still on sirolimus treatment, which has been tolerated well up to the time of this report. CONCLUSIONS The pancreas is a rare location of KHE, which is a locally aggressive vascular tumor. Diagnosis is based on histological findings, and therapy should be multidisciplinary and individualized. Although sirolimus has been very successful in the treatment of KHE even without radical surgery, the possible risks of tumor recurrence and adverse effects warrant some caution.

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
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
BACKGROUND To investigate the clinical characteristics of gastric duplication (GD) in children. METHODS The clinical data of 17 children with GD who were treated in our hospital from July 2015 to June 2021 were analyzed retrospectively. There were 8 males and 9 females, aged from 2 months to 11 years. All children underwent laparoscopic GD resections and postoperative pathological diagnosis was GD. In addition, we searched and analyzed the literature on GD in children from 1 January 2011 to 31 December 2021 from the PubMed, EMBASE, and Cochrane Library databases. RESULTS Gastric duplication was more common in females, with the most common cystic type occurring in the greater curvature of the stomach. Vomiting is the most common clinical manifestation. Ultrasound is an effective method for the early screening of GD. In this study, one patient who had multiple GDs underwent laparoscopic cystectomy and mucosectomy, one patient was converted to open surgery, and all other children underwent laparoscopic cystectomies. The time to oral intake was 2.3 ± 1.0 days (range: 1-4 days), and the postoperative hospital stay was 5.7 ± 1.7 days (range: 2-9 days). All children were followed up for 6-77 months and had an uneventful recovery with the resolution of the preoperative symptoms. CONCLUSION Gastric duplication in children lacks specific clinical manifestations, and the preoperative diagnosis rate is not high, so surgical exploration combined with pathological examination is often needed to make a clear diagnosis. Laparoscopic cystectomy can achieve good therapeutic results.

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
Background: To investigate the effect of embedded hepaticojejunostomy in children with pancreaticobiliary maljunction (PBM) without biliary dilatation. Materials and Methods: The clinical data of 10 patients with nondilated PBM from February 2017 to July 2020 were retrospectively analyzed. Perioperative liver function indexes were compared. Results: All patients were diagnosed by magnetic resonance cholangiopancreatography (MRCP) combined with intraoperative cholangiography. There were 5 cases of Komi type I and 5 cases of type II; the diameter of the common bile duct was 4-9 mm (median: 6 mm); and the length of the common channel was 5-15 mm (median: 9.25 mm). The procedure for one patient with common duct stones was converted to open surgery. Laparoscopic cholecystectomy, common bile duct resection, and embedded hepaticojejunostomy were successfully performed in all 10 cases. The average operation time was 225 ± 96.64 min, and the intraoperative blood loss was 2-5 mL. The mean time to oral intake was 3.5 ± 1.65 days (range: 2-5 days), and the mean hospitalization duration was 6.2 ± 2.44 days (range: 5-8 days). The differences in liver function indexes in the perioperative period were statistically significant (P < .05). The patients were followed-up for 13 to 54 months (median: 40 months). All patients grew well and there was no bile duct dilatation, calculus, or cirrhosis on B-ultrasound examinations. Conclusions: The clinical manifestations of nondilated PBM are often concealed, and preoperative MRCP was important for obtaining a diagnosis. Laparoscopic cholecystectomy, common bile duct resection, and embedded hepaticojejunostomy are feasible for treating nondilated PBM.

Abstract
Hirschsprung disease (HSCR) is an infrequent congenital intestinal dysplasia. The known genetic variations are unable to fully explain the pathogenesis of HSCR. The α/β‐hydratase domain 1 (ABHD1) interferes with the proliferation and migration of intestinal stem cells. Docking protein 6 (DOK6) is involved in neurodevelopment through RET signalling pathway. We examined the association of ABHD1 and DOK6 genetic variants with HSCR using 1470 controls and 1473 HSCR patients from Southern Chinese children. The results clarified that DOK6 rs12968648 G allele significantly increased HSCR susceptibility, in the allelic model (p = 0.034; OR = 1.12, 95%CI = 1.01~1.24) and the dominant model (p = 0.038; OR = 1.12, 95%CI = 1.01~1.25). Clinical stratification analysis showed that rs12968648 G allele was associated with increased risk of short‐segment HSCR (S‐HSCR), in the allelic model (p = 0.028; OR = 1.14, 95%CI = 1.01~1.28) and the additive model (p = 0.030; OR = 1.14, 95%CI = 1.01~1.28). ABHD1 rs2304678 C allele had higher risk to develop total colonic aganglionosis (TCA) in the allelic model (p = 7.04E‐03; OR = 1.67, 95%CI = 1.15~2.43) and the dominant model (p = 4.12E‐03; OR = 1.93, 95%CI = 1.23~3.04). DOK6 rs12968648 and ABHD1 rs2304678 had significant intergenic synergistic effect according to logical regression (p = 0.0081; OR = 0.76, 95%CI = 0.63~0.93) and multifactor dimensionality reduction (MDR, p = 0.0045; OR = 1.25, 95%CI = 1.07~1.46). This study verified two susceptible variations of HSCR on ABHD1 and DOK6. Their roles in HSCR should be conducted in further studies.

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.
