Abstract
Objective: To explore the association between polygenic risk score (PRS) and age at onset and early-onset risk of gastric cancer (GC). Methods: Gastric cancer cases from existing genome-wide association study were included, and 112 single nucleotide polymorphisms associated with GC risk were used to derive individual PRS. Analysis of variance and Pearson correlation test was used to depict the relationship between PRS and GC onset age. Cases diagnosed before 50 years old were defined as early-onset gastric cancer. Cox proportional hazard model was used to test the association between PRS and early-onset GC risk with early-onset age as the timescale and low genetic risk (PRS ≤20%) as the reference group. Results: A total of 8 629 cases, including 6 284 males (72.82%) and 2 345 females (27.18%), were included, and the mean age was (60.61±10.80) years old. The PRS was negatively correlated with age of GC onset (r=-0.05, P<0.001). The mean age of gastric cancer cases with low, intermediate, and high genetic risk were (61.68±10.33), (60.53±10.79), (59.80±11.20), respectively. PRS was significantly associated with the risk of early-onset GC in a dose-response manner (intermediate genetic risk: HR=1.19, 95%CI: 1.03-1.39, P=0.022; high genetic risk: HR=1.44, 95%CI: 1.20-1.71, P<0.001). Conclusions: PRS may contribute to the risk of both GC and early-onset GC. PRS can be used as a measurable indicator for risk prediction for occurrence and early-onset of GC.

Abstract
Background:Patients with systemic lupus erythematosus (SLE) have a substantially increased risk of venous thromboembolism (VTE). An individual VTE risk assessment is important to ensure that all patients are assessed and given adequate thromboprophylaxis.Objectives:We conducted this study to develop a risk score for VTE in patients with SLE.Methods:Patients with SLE who participated in the Chinese SLE Treatment and Research group were enrolled in this study. Patient baseline information and clinical laboratory indicators were obtained, and VTE events were recorded every 3-6 months during follow-up visits. The risk prediction model was created and internally validated using the bootstrap methods, and a scoring system was established (Figure 1).Figure 1.Flow chart of study design.Results:Out of 4,502 patients included in this study, 135 had a VTE event. After univariate analysis and Lasso regression, the following 11 variables were identified and included in the risk prediction model: male sex, age, BMI ≥25 kg/m2, hyperlipidemia, hypoalbuminemia, hsCRP>3 mg/L, renal involvement, nervous system involvement, anti-β2-glycoprotein I antibody positivity, lupus anticoagulant positivity, and no use of hydroxychloroquine. The AUC for the SLE-VTE score (Table 1) was 0.947 (95% CI, 0.9249-0.9694). The SLE-VTE score’s sensitivity and specificity with the optimal cutoff value of 13 were 0.919 and 0.881, respectively. The SLE-VTE score was superior to the GAPSS system in predicting the risk of VTE in patients with SLE (AUC= 0.947 vs. 0.680, P< 0.001; integrated discrimination improvement (IDI)= 0.6652, P< 0.001; net reclassification improvement (NRI)= 0.6652, P< 0.001).Table 1.Final multivariable analysis for venous thromboembolism risk in patients with SLE β coefficientsOdds ratio* (95% CI)P-valuePoints in scoring systemMale0.6211.86(0.953-3.503)0.0612Age at study entry(≥50)0.8372.308(1.339-3.915)0.0023BMI02(kg/m20.7922.209(1.333-3.627)0.0023Hyperlipemia0.8382.313(1.246-4.166)0.0063Hypoalbuminemia2.1638.697(5.185-14.794)< 0.0017hsCRP>3 mg/L1.4524.272(2.618-6.968)< 0.0015Anti β2GPI1.0132.754(1.543-4.853)0.0013LA1.5594.752(2.799-8.072)< 0.0015Nervous system2.38210.832(6.163-18.998)< 0.0018Lupus nephritis0.8352.305(1.414-3.756)0.0013No use of hydroxychloroquine1.7715.876(3.722-9.401)< 0.0016BMI: body mass index; hsCRP: Hypersensitive c-reactive protein; ACL: anticardiolipin, antiβ2GPI: anti-β2-glycoprotein I, LA: lupus anticoagulantm;Values in bold are statistically significant at p <0.05.Conclusion:Various factors are related to the occurrence of VTE in patients with SLE.

Abstract
AIMS Wuyiencin is a nucleoside antibiotic produced by Streptomyces albulus CK-15. The aim of this study was to determine whether wuyiencin can be used, as a suitable alternative to chemical pesticides, to protect cucumbers (Cucumis sativus L.) from powdery mildew caused by Sphaerotheca fuliginea. Further, the mechanisms underlying the control of cucumber powdery mildew by S. albulus CK-15 were preliminarily elucidated. METHODS AND RESULTS Wuyiencin solutions of different concentrations were used to treat infected cucumber plants under greenhouse conditions. The results indicated that wuyiencin could significantly reduce powdery mildew disease incidence, with a maximum prevention efficacy of 94·38%. Further, scanning electron micrographs and enzyme assays showed that wuyiencin inhibited S. fuliginea spore growth and elicited the activity of plant systemic resistance-related enzymes. Additionally, real-time quantitative reverse transcription PCR suggested that wuyiencin can activate a salicylic acid-dependent plant defence response. CONCLUSIONS Wuyiencin produced by S. albulus CK-15 possessed antifungal effects and was able to mitigate cucumber powdery mildew disease via antagonistic action. Wuyiencin also induced defence responses in the plants. SIGNIFICANCE AND IMPACT OF THE STUDY These results reinforce the biotechnological potential of wuyiencin as both an antagonistic agent and an inducer of plant systemic resistance.

Abstract
Objective: To analyze the distribution and variance of neonatal pulse oxygen saturation (SpO2) at different altitudes in China, and provide a new evidence for the screening of NCHD at high altitudes. Methods: Based on the database of National Screening Project of NCHD, the distribution of SpO2 values was described in 26 766 newborns at altitudes of 0-100 m, 600-700 m, 900-1 100 m, 1 400-1 600 m, 1 900-2 100 m, and 2 200-2 500 m. One-way analysis of variance was used to analyze the differences among SpO2 values in newborns at different altitudes. Results: The average SpO2 values of right hand in newborns at altitudes of 0-100 m, 600-700 m, 900-1 100 m, 1 400-1 600 m, 1 900-2 100 m and 2 200-2 500 m were 97.7%±1.4%, 97.1%±1.1%, 96.1%±1.3%, 96.0%±1.7%, 95.9%±1.7% and 95.5%±2.4%, respectively. And corresponding average SpO2 values of either foot were 97.7%±1.4%, 96.9%±1.1%, 96.3%±1.4%, 96.0%±1.7%, 95.6%±1.8% and 95.2%±2.7%, respectively. There were statistically significant differences in the average SpO2 values of newborns at different altitudes (right hand: F=1 248.35, P<0.001; either foot: F=1 280.45, P<0.001). The SpO2 of newborns tended to be lower with the increase of altitudes (P-trend<0.001). Conclusion: SpO2 values in newborns were negatively associated with the altitudes, which indicated that the cut-off value of screening for NCHD at sea level might not be applicable to newborns at higher altitudes. Thus, it is worthwhile to conducted studies on the normal values of SpO2 and the cut-off value of screening for NCHD in newborns at high altitudes.

Abstract
Background:Patients with autoimmune disease often require immunosuppressive medications that may increase their risk of developing severe illness from COVID-19. The importance of immunization in this population is particularly high. While the studied vaccines show efficacy in the general population, nothing is known regarding the immune response or safety profile in patients with autoimmune disease and those taking immunomodulatory medications.Objectives:To assess the safety profile and degree of adverse events from SARS-CoV-2 vaccines in patients with autoimmune and inflammatory disease.Methods:This study is part of a larger prospective observational study examining the immunogenicity and safety profile of the SARS-CoV-2 vaccine in patients with immune-mediated diseases taking immunomodulatory medications. Adults with an immune-mediated disease scheduled to receive either a Pfizer or Moderna SARS-COV-2 vaccine were enrolled in this study. Subjects participated in 3 study visits (pre-vaccine, dose 1 (D1) and dose 2 (D2)) where blood, for immunologic assays, and clinical data were collected. Assessments of adverse events (AE), including local and systemic symptoms and validated degree of AE severity were solicited within 7 days of receiving each vaccine dose.Results:To date, 70 patients with autoimmune and inflammatory disease have been enrolled. Demographic and clinical characteristics are shown in Table 1. Distribution of current immunomodulatory medications included prednisone 18.6%, conventional synthetic DMARD 55.7%, targeted synthetic DMARD 4.3%, and biologic DMARD 68.5%. Almost all participants experienced an adverse event following vaccination (D1 96%, D2 100%). Following D1 AEs were generally mild (76.5%) whereas following D2 a large portion of patients experienced AEs that were moderate (47.8%) and severe (30.5%). Injection site pain was the most common AE following both doses followed by arthralgias (D1 21.6%, D2 78.2%), fever (D1 21.6%, D2 70%) and fatigue (D1 21.6%, D2 65.2%) (Figure 1).Figure 1.Solicited Local and Systemic Adverse Events. Percentage of participants who had endorsed an adverse event within 7 days of first or second dose of SARS-CoV-2 Vaccine. ‘Other’ symptoms included chills, blurry vision, brain fog and dizziness.Conclusion:Patients with autoimmune and inflammatory disease experience a significant burden of adverse events following SARS-CoV-2 vaccination with both frequency and severity appearing greater than that of the reported results from the vaccine clinical trials. Several of the endorsed AEs such as fever, fatigue and arthralgias can also be commonly seen in rheumatologic diseases, mimicking flares. While SARS-CoV-2 immunization is crucial in patients with autoimmune diseases, this study demonstrates the importance of understanding the AEs experienced by this patient population to better inform patients of possible expected side effects of SARS-CoV-2 vaccination and further management in the future.Table 1.Demographic and Clinical Characteristics of ParticipantsParameter N (%)N=70Age [years], mean (SD)Age group48.3 ± 16.4 < 6553 (75.7) 65+17 (24.3)Gender Female48 (68.6) Male20 (38.5) Other2 (2.9)Race White47 (67.1) Asian14 (20.0) Hispanic8 (11.4) Black1 (1.4) BMI [kg/m2], mean (SD)25.0 ± 5.4Immunologic Diagnosis Rheumatoid Arthritis21 (30.0) Spondyloarthritis*21 (30.0) Systemic Lupus Erythematous8 (11.4) Connective Tissue Disease, Other‡12 (17.1) Vasculitis3 (4.2) Inflammatory Bowel Disease7 (10.0) Autoinflammatory Syndrome5 (7.1) Multiple Sclerosis2 (2.9) IgG4 Related Disease2 (2.9)Disease Duration [years], mean (SD)9.0 ± 5Medications Prednisone13 (18.6)DMARDs Hydroxychloroquine16 (22.9) Methotrexate15 (21.4) Sulfasalazine6 (8.6) Tofacitinib3 (4.3) Azathioprine2 (2.9)Biologics TNF inhibitor33 (47.1) Rituximab7 (10) Abatacept6 (8.6) IL-23 inhibitor2 (2.9)* Spondyloarthritis includes Axial Spondyloarthritis and Psoriatic Arthritis. ‡ Other Connective Tissue Disease includes scleroderma, Sjogren’s syndrome, polymyositis, and UCTD.Disclosure of Interests:Monica Yang: None declared, Patti Katz: None declared, Diana Paez: None declared, Alexander Carvidi: None declared, Mehrdad Matloubian: None declared, Mary Nakamura: None declared, Lianne S.

Abstract
TheH-Tphase diagram of Ni3V2O8is very rich and remains puzzling in a high magnetic field range. Through the state-of-the-art specific heat measurement in pulsed high field to 35 T and magnetocaloric effect measurement up to 45 T, we successfully construct the high-field phase diagram of Ni3V2O8for fields applied along thebaxis. The phase boundaries are corrected for previous results by magnetization and magneto-optical measurements. The resulting phase diagram shows that the high temperature incommensurate (HTI) phase develops well to high fields and low temperatures. In addition to the early reported C', C, low temperature incommensurate (LTI) and HTI phases, we explore a new magnetic ordered phase called HF1 in fields of 10-30 T. A multicritical point is also observed at 6 K and 8 T. Furthermore, the specific heat data reveal enhancements of the anomalies at ∼4 K, probably associated with a strong spin-lattice coupling in this frustrated multiferroic material.

Abstract
Objectives: The mortality rate of sepsis remains very high. Metabolomic techniques are playing increasingly important roles in diagnosis and treatment in critical care medicine. The purpose of our research was to use untargeted metabolomics to identify and analyze the common differential metabolites among patients with sepsis with differences in their 7-day prognosis and blood PD-1 expression and analyze their correlations with environmental factors. Methods: Plasma samples from 18 patients with sepsis were analyzed by untargeted LC-MS metabolomics. Based on the 7-day prognoses of the sepsis patients or their levels of PD-1 expression on the surface of CD4+ T cells in the blood, we divided the patients into two groups. We used a combination of multidimensional and monodimensional methods for statistical analysis. At the same time, the Spearman correlation analysis method was used to analyze the correlation between the differential metabolites and inflammatory factors. Results: In the positive and negative ionization modes, 16 and 8 differential metabolites were obtained between the 7-day death and survival groups, respectively; 5 and 8 differential metabolites were obtained between the high PD-1 and low PD-1 groups, respectively. We identified three common differential metabolites from the two groups, namely, PC (P-18:0/14:0), 2-ethyl-2-hydroxybutyric acid and glyceraldehyde. Then, we analyzed the correlations between environmental factors and the common differences in metabolites. Among the identified metabolites, 2-ethyl-2-hydroxybutyric acid was positively correlated with the levels of IL-2 and lactic acid (Lac) (P < 0.01 and P < 0.05, respectively). Conclusions: These three metabolites were identified as common differential metabolites between the 7-day prognosis groups and the PD-1 expression level groups of sepsis patients. They may be involved in regulating the expression of PD-1 on the surface of CD4+ T cells through the action of related environmental factors such as IL-2 or Lac, which in turn affects the 7-day prognosis of sepsis patients.

Abstract
OBJECTIVE To detect the expression of long non-coding ribonucleic acid (lncRNA) ASB16-AS1 in non-small cell lung cancer (NSCLC) tissues and cells, and to explore the effect of lncRNA ASB16-AS1 on the biological functions of NSCLC cells. PATIENTS AND METHODS The expression level of lncRNA ASB16-AS1 in NSCLC tissues and cells was detected via real-time fluorescence quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR). The interference sequences of lncRNA ASB16-AS1 were designed and synthesized, and its transfection efficacy was detected by qRT-PCR. After knockdown of lncRNA ASB16-AS1, the proliferation, cell cycle, and apoptosis of NSCLC cells were detected via cell counting kit-8 (CCK-8) assay, colony formation assay, and flow cytometry, respectively. Moreover, the expression changes in the Wnt/β catenin signaling pathway were detected via Western blotting. RESULTS LncRNA ASB16-AS1 was upregulated in NSCLC tissues and cells compared with that in paracarcinoma tissues and 16HBE cells. The results of CCK-8 assay and colony formation assay revealed that the silence of lncRNA ASB16-AS1 attenuated the proliferative ability in NSCLC. The results of flow cytometry manifested that the silence of lncRNA ASB16-AS1 arrested the cell cycle in G0/1 phase, and accelerated the apoptosis rate. The key proteins in the Wnt/β-catenin signaling pathway were regulated by lncRNA ASB16-AS1 in NSCLC. CONCLUSIONS LncRNA ASB16-AS1 is upregulated in NSCLC tissues and cells, which promotes proliferation and inhibits apoptosis of NSCLC cells through the Wnt/β-catenin signaling pathway.

Methods: A total of 49 children with moderate to severe HIE admitted to the Children's Hospital Affiliated to Nanjing Medical University from July 2015 to September 2018 were retrospectively analyzed. Cranial magnetic resonance imaging (MRI) data of 31 full-term neonates without neurological symptoms and signs who visited the hospital during the same period were recruited as the control group. ImgJ software was used to delineate the whole brain area at the thalamus/basal ganglia level as the area of interest, and MRIcron software was used to obtain ADC histogram parameters. The differences of ADC histogram parameters between HIE group and control group were compared. The correlation between ADC histogram parameters and neonatal neurobehavioral neurological assessment (NBNA) in HIE group was analyzed. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficiency of each parameter. Results: The mean value, minimum value, maximum value, mode-value, variance, heterogeneity and 10%-90% ADC values of HIE group were all greater than those of the control group(634±65,310±36,1 683±18,711±87,66 928±921,5 907±204,477±50,513±53,542±56,568±59,591±61,625±92,661±97,709±105,811±119),the differences were statistically significant(all P<0.05), while mode-count of HIE group was smaller than that of the control group(272±22 to 395±83), and the difference was statistically significant (t=2.996,P<0.05). All the above parameters with statistical differences were correlated with NBNA score, among which mode-count was negatively correlated with NBNA score(r=-0.369,P<0.05), and the rest were positively correlated(all P<0.05). The area under the ROC curve (AUC) of variance had the highest diagnostic efficiency (0.881), followed by 90% ADC value and ADC maximum value. Conclusion: ADC histogram is helpful for the diagnosis of HIE, objectively and quantitatively reflecting the diffusion information of brain, and assessing the severity of HIE.

Abstract
The electron valley and spin degree of freedom in monolayer transition-metal dichalcogenides can be manipulated in optical and transport measurements performed in magnetic fields. The key parameter for determining the Zeeman splitting, namely, the separate contribution of the electron and hole g factor, is inaccessible in most measurements. Here we present an original method that gives access to the respective contribution of the conduction and valence band to the measured Zeeman splitting. It exploits the optical selection rules of exciton complexes, in particular the ones involving intervalley phonons, avoiding strong renormalization effects that compromise single particle g-factor determination in transport experiments. These studies yield a direct determination of single band g factors. We measure g_{c1}=0.86±0.1, g_{c2}=3.84±0.1 for the bottom (top) conduction bands and g_{v}=6.1±0.1 for the valence band of monolayer WSe_{2}. These measurements are helpful for quantitative interpretation of optical and transport measurements performed in magnetic fields. In addition, the measured g factors are valuable input parameters for optimizing band structure calculations of these 2D materials.

Abstract
OBJECTIVE The aim of this study was to analyze the association of ATPase plasma membrane Ca2+ transporting 1 (ATP2B1) gene polymorphism with the incidence of eclampsia, and to investigate the possible underlying mechanism. PATIENTS AND METHODS ATP2B1 genotype and allele distributions in umbilical venous blood cells were analyzed in 50 control subjects and 117 eclampsia patients via Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and TaqMan genotyping technique. Meanwhile, the differences in the single nucleotide polymorphisms at rs2681472 and rs17249754 in the case group and control group were analyzed using the χ2-test. The risk factors for eclampsia were analyzed via univariate, multivariate, and Logistic regression analyses. Furthermore, the associations of rs2681472 gene polymorphism with risk factors for eclampsia (hypertension and lower extremity edema) were verified via χ2-test. RESULTS The statistically significant differences were observed in the gestational week, body mass index, blood pressure, and incidence rates of proteinuria and lower extremity edema of pregnant women between the case group and the control group (p<0.05). Meanwhile, the genotype and allele distributions at rs2681472 in the case group were remarkably different from those of the control group (p<0.05). However, no evident differences were observed at rs17249754 between the two groups (p>0.05). According to univariate, multivariate, and logistic regression analyses, hypertension, and lower extremity edema were significantly associated with the incidence of eclampsia (p<0.05). In addition, the gene polymorphism at rs2681472 showed significant differences among subjects with and without hypertension and lower extremity edema (p<0.05). CONCLUSIONS ATP2B1 gene polymorphism at rs2681472 shows significant differences between eclampsia patients and normal controls. Moreover, its gene polymorphism is closely related to the occurrence of hypertension and lower extremity edema.

Abstract
The overall goal of this study is to investigate the effect of sulfidated nanoscale zerovalent iron (S-nZVI) on the removal of hexavalent molybdate (MoO42-) under different aquatic chemistry conditions. Surface analysis suggests that Mo(VI) is removed mainly by adsorption and co-precipitation onto the surface of S-nZVI and a small amount of Mo(VI) can be reduced to Mo(V) species. The results of batch tests show that Mo(VI) removal by S-nZVI are well described with the pseudo-second-order adsorption model. The removal rate increases with a decrease in solution pH (4.0-9.0) and is significantly affected by the S/Fe ratio of S-nZVI, with the optimal S/Fe ratio being 0.5. The presence of anions WO42- or CrO42- can reduce the Mo(VI) removal, which is likely because they compete for adsorption sites on the solid surfaces. The divalent cations Ni2+, Cu2+ and Co2+ also inhibit the removal of Mo(VI) whereas Zn2+, Ca2+ and Mg2+ enhance it. After being aged for 35 d in water, S-nZVI still exhibits high reactivity towards Mo(VI) removal (57.39%). The study demonstrates that S-nZVI can be used as an environmentally friendly material for effectively removing Mo(VI) from contaminated water.

Abstract
OBJECTIVES Older adults with frailty are vulnerable to cardiovascular event and subsequent mortality. Frailty and albuminuria share atherosclerotic risk factors. The present study investigated the association of frailty and albuminuria among elderly Chinese inpatients. DESIGN Cross-sectional study. SETTINGS AND PARTICIPANTS A total of 202 patients aged over 60 years from the Center of Gerontology and Geriatric, West China Hospital. MEASUREMENTS Frailty was defined using the five-item FRAIL scale. This included measurements of fatigue, resistance, ambulation, illness, and loss of weight. We further determined the random urine albumin/creatinine ratio (UACR) of all patients. Random UACR ≥30 mg/g was defined as albuminuria, and < 30mg/g as normoalbuminuria. The relationship between albuminuria and frailty was assessed through multiple regression analysis. RESULTS The 202 participants (156 men, 77.2%) had an average age of 78.99±7.60 years, which ranged from 60 to 95. Compared to those without albuminuria, elderly patients with albuminuria were of an older age, had a higher prevalence of diabetes and poorer renal function. The prevalence of frailty, pre-frailty and ambulation (one of the FRAIL components) were higher in the albuminuria group than the normoalbuminuria group (23.9% vs. 12.2%, 47.9% vs.37.4%, 33.8% vs. 16.0%, respectively, P<0.05). Following the adjustment for age, eGFR, hypertension, diabetes and using ACEI/ARB, being frail or pre-frail led to an enhanced risk of albuminuria (OR frail 2.60, 95% CI frail 1.01-6.72; OR pre-frail 2.14, 95% CI pre-frail 1.03-4.44). CONCLUSIONS Frailty is independently associated with albuminuria when adjusted for classic cardiovascular risk factors.

Abstract
Purpose This study was performed to investigate the effect of miRNA let-7a-5p on the proliferation, invasion, and migration of human hepatoma cells as well as to determine BZW2 expression in these cells. Methods Western blotting and real-time quantitative polymerase chain reaction were used to detect changes in the expression of miRNA let-7a-5p and BZW2 protein and gene, respectively. A luciferase reporter gene assay was used to examine whether BZW2 is the target gene of miR-let-7a-5p. The effect of miR-let-7a-5p on the invasion, migration, and proliferation of human hepatoma Bel-7404 and HepG2 cells was determined using the transwell invasion assay, scratch test, and CCK-8 assay, respectively. Flow cytometry was used to assess the effect of miR-let-7a-5p and BZW2 expression on apoptosis of hepatoma cells. Results The luciferase reporter gene assay identified BZW2 as the target gene of miR-let-7a-5p. Moreover, increased expression of miR-let-7a-5p was found to significantly decrease BZW2 expression; inhibit proliferation, invasion, and migration; and promote apoptosis of hepatoma cells. Conclusion miR-let-7a-5p can inhibit proliferation, invasion, and migration as well as promote apoptosis of hepatoma cells by decreasing BZW2 expression.

Abstract
Previous studies have indicated that each conotoxin precursor has a hyperconserved signal region, a rather conserved pro region and a hypervariable mature region, and nucleotide mutations are the main driven factor. However, in this study, we made an in-depth analysis on the M-superfamily conotoxin precursors and found that the diversity of the signal, pro and mature regions are more complicated than previous findings. Different conotoxin precursors can have same signal, pro and/or mature regions, especially different conotoxin precursors with same mature region but different signal and pro regions. In addition, insertions and deletions (indels) were detected in conotoxin precursors. Indels are infrequent in the signal region but frequent in the pro and mature regions. In contrast to deletions that dominate in the pro region, insertions dominate in the mature region. The number of amino acids is crucial for the physiological functions of mature conotoxins, therefore indels, especially insertions in the mature region, play an important role in the sequence and function diversity of conotoxins.

Abstract
Dual-energy computed tomography (DECT) has shown a great potential for lowering range uncertainties, which is necessary for truly leveraging the Bragg peak in proton therapy. However, analytical stopping-power-ratio (SPR) estimation methods have limitations in resolving the influence from the beam-hardening artifact, i.e. CT number variation of the same object scanned under different imaging conditions, such as different patient size and location in the field-of-view (FOV). We present a convolutional neural network (CNN)-based framework to estimate proton SPR that accounts for patient geometry variation and addresses CT number variation. The proposed framework was tested on both prostate and head-and-neck (HN) patient datasets. Simulated CT images were used in order to have a well-defined ground-truth SPR for evaluation. Two training scenarios were evaluated: training with patient CT images (ideal scenario) and training with computational phantoms (realistic scenario). For the training in ideal scenario, computational phantoms were created based on 120 kVp patient CT images using a custom-defined density and material translation curve. Then, 80 kVp and 150 kVp Sn DECT image pairs were obtained using ray-tracing simulation, and their corresponding SPR was calculated from the known density and elemental compositions. For the training in realistic scenario, computational phantoms were created based on the geometry of calibration phantoms. For both scenarios, evaluation was performed on the phantoms created from patient CT images. Compared to a conventional parametric model, U-net trained with computational phantoms (realistic scenario) reduced the SPR estimation uncertainty (95th percentile) of the prostate patient from 1.10% to 0.71%, and HN patient from 2.11% to 1.20%. With the U-net trained with patient images (ideal scenario) uncertainty values were 0.32% and 0.42% for prostate and HN patients, respectively. These results suggest that CNN has great potential to improve the accuracy of SPR estimation in proton therapy by incorporating individual patient geometry information.
