Abstract Objective: To investigate the incidence, clinical and genetic characteristics of pediatric lymphoma patients of China with inborn errors of immunity (IEI)-related gene mutations, which have not been fully studied. Method: From Jan. 2020 to Mar. 2023, IEI-related genetic mutations were retrospectively explored in 108 children with lymphomas admitted to Beijing Children’s Hospital by NGS. Genetic rule and clinical characteristics as well as treatment outcomes were compared between patients with or without IEI-related gene mutations. Results: A total of 17 patients (15.7 %) harbored IEI-associated mutations, including 4 cases with X-linked lymphoproliferative syndrome (XLP), 3 cases had mutations in tumor necrosis factor receptor superfamily 13B (TNFRSF13B), 2 cases with Activated p110 syndrome (APDS). Patients with IEI all had alteration of immunocompetence with decreased levels of immunoglobulin and lymphocyte subsets. Recurrent infection existed in 41.2 % of patients. The 18-month event-free survival (EFS) and the overall response rate (ORR) of patients with IEI are significantly lower than those without IEI (33.86% vs. 73.26 %, p = 0.011; 52.94% vs. 87.91 %, p = 0.002, respectively). In addition, patients with IEI had a higher progression disease (PD) rate of 23.5 % than those without IEI of 4.4% (p = 0.006). Conclusion: The present study demonstrated that IEI-associated lymphomas were much more common than originally appreciated in pediatric lymphomas, and those were insensitive to treatment and more likely to progress or relapse. The genomic analysis and a thorough review of the medical history of IEI can be used to distinguish them from pediatric lymphomas without IEI, which are beneficial for the early diagnosis and direct intervention.

RESUMEN La inundación de CO2 para la recuperación de petróleo es un proceso dinámico que requiere más investigación sobre las características de cambio de la interfaz petróleo-gas, los procesos de transferencia de masa interfacial y la variación de la composición petróleo-gas durante el desplazamiento tanto inmiscible como miscible. Comprender estos factores es crucial para comprender mejor su impacto en la recuperación de petróleo mejorada con CO2 (EOR). Esta investigación adopta un aparato experimental de inundación visual miscible con CO2 desarrollado conjuntamente para estudiar las características dinámicas horizontales del CO2 y el petróleo crudo bajo diferentes presiones y caudales en un tubo visual delgado. A 10 MPa, los resultados de la estratificación del CO2 y del petróleo crudo indican que el experimento es una inundación inmiscible. El ángulo de contacto (7,9°) entre las dos fases de CO2 y el petróleo crudo a un caudal de 15 cm/min es mayor que el (5,2°) a 1,5 cm/ min, y la escala de grises del CO2 aumenta a 100 cm/min. La cantidad, el contenido individual y la forma de los componentes de hidrocarburos ligeros y medios condensados en la pared interior del tubo varían con diferentes caudales. A 15 MPa, la aparición del intervalo de transición de CO2 y petróleo crudo demuestra que el experimento es una inundación miscible. A diferentes caudales, el ángulo de inclinación y la distribución de las franjas negras son diferentes. Todo el intervalo de transición se divide en 6 intervalos y el intervalo de transición se alarga al aumentar la velocidad del fluido. Los experimentos demuestran visualmente la aparición de la fase miscible e identifican la presión experimental y el caudal de fluido como factores clave que influyen en la miscibilidad del CO2 y el petróleo crudo.

ABSTRACT CO2 flooding for oil recovery is a dynamic process that requires further investigation of oil-gas interface change characteristics, interfacial mass transfer processes, and oil-gas composition variation during both immiscible and miscible displacement. Understanding these factors is crucial for better comprehending their impact on CO2-enhanced oil recovery (EOR). This research used a jointly developed CO2 miscible visual flooding experimental apparatus to study the horizontal dynamic characteristics of CO2 and crude oil under different pressures and flow rates in visual slim tube. At 10 MPa, the stratification results of CO2 and crude oil indicate that the experiment is immiscible flooding. The contact angle (7.9°) between the two phases of CO2 and crude oil at the flow rate of 15 cm/min is larger than that (5.2°) at 1.5 cm/min, and the grey scale of CO2 increases at 100 cm/min. The quantity, individual content, and shape of the light and medium hydrocarbon components condensed on the inner wall of the tube vary with different flow rates. At 15 MPa, the appearance of the CO2 and crude oil transition interval proves that the experiment is miscible flooding. At different flow rates, the inclination angle and distribution of black stripes vary. The whole transition interval is divided into 6 intervals, and the transition interval lengthens with increasing fluid velocity. The experiments visually demonstrate the occurrence of the miscible phase, and identify experimental pressure and fluid flow rate as key factors influencing the miscibility of CO2 and crude oil.

Abstract Objectives: Allergic diseases and Meniere’s disease found to have a possible link in observational study. However, the potential causal relationship between the two is unclear. Therefore, we aimed to explore the causal relationship between allergic diseases and Meniere’s disease using a new data analysis technique called bidirectional Mendelian randomization study. Method: Summary-level statistics for Meniere’s disease and three allergic diseases (asthma, allergic rhinitis, eczema/dermatitis) were obtained from large-scale genome-wide association studies. The inverse variance weighted method was used as the primary measure, supplemented by MR-Egger regression and the weighted median method. To ensure the reliability of the conclusions, Cochran’s Q, MR-Egger intercept, MR-PRESSO test, leave-one-out test, and MR Steiger test were used. Results: Inverse-variance weighted method showed asthma (p = 0.008, OR = 3.908, 95% CI 1.424 − 10.724, adjust p = 0.024), allergic rhinitis (p = 0.026, OR = 24.714, 95% CI 1.479 − 412.827, adjust_p = 0.026) and eczema/dermatitis (p = 0.019, OR = 3725.954, 95% CI 3.795 to 3,658,399.580, adjust_p = 0.029) all had a significant effect on Meniere’s disease. Reverse Mendelian randomization studies have shown that Meniere’s disease does not increase the risk of three allergic diseases. Sensitivity analysis showed no horizontal pleiotropy and heterogeneity for each trait. Conclusion: Our Mendelian randomization analysis supports a positive causal relationship between three allergic diseases (asthma, allergic rhinitis, eczema/dermatitis) and Meniere’s disease. This suggests that physicians should pay more attention to the Meniere’s patient’s allergy history and consider allergy avoidance as part of their treatment plan. Level of evidence: Mendelian Randomized (MR) studies are second only to randomized controlled trials in terms of the level of evidence.

Abstract Autophagy-related gene (ATG) 5 regulates blood lipids, chronic inflammation, CD4+ T-cell differentiation, and neuronal death and is involved in post-stroke cognitive impairment. This study aimed to explore the correlation of serum ATG5 with CD4+ T cells and cognition impairment in stroke patients. Peripheral blood was collected from 180 stroke patients for serum ATG5 and T helper (Th) 1, Th2, Th17, and regulatory T (Treg) cell detection via enzyme-linked immunosorbent assays and flow cytometry. The Mini-Mental State Examination (MMSE) scale was completed at enrollment, year (Y)1, Y2, and Y3 in stroke patients. Serum ATG5 was also measured in 50 healthy controls (HCs). Serum ATG5 was elevated in stroke patients compared to HCs (P<0.001) and was positively correlated to Th2 cells (P=0.022), Th17 cells (P<0.001), and Th17/Treg ratio (P<0.001) in stroke patients but not correlated with Th1 cells, Th1/Th2 ratio, or Treg cells (all P>0.050). Serum ATG5 (P=0.037), Th1 cells (P=0.022), Th17 cells (P=0.002), and Th17/Treg ratio (P=0.018) were elevated in stroke patients with MMSE score-identified cognition impairment vs those without cognition impairment, whereas Th2 cells, Th1/Th2 ratio, and Treg cells were not different between them (all P>0.050). Importantly, serum ATG5 was negatively linked with MMSE score at enrollment (P=0.004), Y1 (P=0.002), Y2 (P=0.014), and Y3 (P=0.001); moreover, it was positively related to 2-year (P=0.024) and 3-year (P=0.012) MMSE score decline in stroke patients. Serum ATG5 was positively correlated with Th2 and Th17 cells and estimated cognitive function decline in stroke patients.

SUMMARY OBJECTIVE: This study aimed to explore and analyze the therapeutic effect of the combination of Bifidobacterium animalis subsp. lactis BB-12® and Lactobacillus rhamnosus GG on underweight and malabsorption in premature infants. METHODS: This is a retrospective study. The clinical data of 68 premature infants admitted to Beijing United Family Hospital (Private Secondary Comprehensive Hospital, Chaoyang District, Beijing, China) from January 2016 to January 2022 were analyzed retrospectively. Preterm infants less than 37 weeks of gestational age admitted to the neonatal intensive care unit were included in the study. Patients with intestinal malformations, necrotizing enterocolitis, etc., who require long-term fasting were excluded. A telephone follow-up was performed 3-6 months after discharge. They were classified as treatment groups A and B according to the treatment plan. The treatment group A included parenteral nutrition, enteral nutrition, etc. In treatment group B, based on treatment group A, the premature infants were treated with Bifidobacterium animalis subsp. lactis BB-12® and Lactobacillus rhamnosus GG. The time to regain birthweight and the weight on day 30 were compared between the two groups, as was the duration of transition from parenteral nutrition to total enteral nutrition. RESULTS: The time of weight regain birthweight in group B was shorter than that in group A (t=-2.560; t=-4.287; p<0.05). The increase of weight on day 30 in group B was significantly higher than that in group A (t=2.591; t=2.651; p<0.05). The time from parenteral nutrition to total enteral nutrition in group B was shorter than that in group A (z=-2.145; z=-2.236; p<0.05). CONCLUSION: In the treatment of premature infants, the combination of Bifidobacterium animalis subsp. lactis BB-12® and Lactobacillus rhamnosus GG can have a better therapeutic effect on the underweight and malabsorption of premature infants, and this treatment method can be popularized in clinics.

ABSTRACT We focus here on the problem of poor real-time performance and low accuracy of seed box allowance detection during wheat sowing operations, and present a real-time weighing system for a seed box allowance. The proposed weighing system obtains the seed box allowance using an ultrasonic sensor and load cell, and displays it in real time via a computer. Based on the proposed weighing system, the weighing structure is also designed for the seed box. At the software level, three filtering methods are proposed to condition the signal, namely mean filtering, median filtering, and the acceleration method, and models of these three filtering algorithms are implemented in MATLAB/Simulink. Experiments to assess the accuracy of the system and filtering algorithm were carried out on the test bench; the results show that the system error is initially in the range −16.3 g to 63.8 g, and is reduced to the range −13.4 g to 15.1 g after correction. No significant difference between the three filtering algorithms is found, but since the acceleration method can improve the response speed of the system, this is selected as the final filtering method. realtime operations cell computer level signal MATLABSimulink MATLAB Simulink MATLAB/Simulink bench 163 16 3 −16. 638 63 8 63. 134 13 4 −13. 151 15 1 15. correction found −16 6 −13 −1 −

The overexpression of P-glycoprotein (P-gp/ABCB1) is a leading cause of multidrug resistance (MDR). Hence, it is crucial to discover effective pharmaceuticals that counteract ABCB1-mediated multidrug resistance. FRAX486 is a p21-activated kinase (PAK) inhibitor. The objective of this study was to investigate whether FRAX486 can reverse ABCB1-mediated multidrug resistance, while also exploring its mechanism of action. The CCK8 assay demonstrated that FRAX486 significantly reversed ABCB1-mediated multidrug resistance. Furthermore, western blotting and immunofluorescence experiments revealed that FRAX486 had no impact on expression level and intracellular localization of ABCB1. Notably, FRAX486 was found to enhance intracellular drug accumulation and reduce efflux, resulting in the reversal of multidrug resistance. Docking analysis also indicated a strong affinity between FRAX486 and ABCB1. This study highlights the ability of FRAX486 to reverse ABCB1-mediated multidrug resistance and provides valuable insights for its clinical application.

Abstract Objective: To investigate the optimal timing of initial intravenous immunoglobulin (IVIG) treatment in Kawasaki disease (KD) patients. Methods: KD patients were classified as the early group (day 1-4), conventional group (day 5-7), conventional group (day 8-10), and late group (after day 10). Differences among the groups were analyzed by ANOVA and Chi-square analysis. Predictors of IVIG resistance and the optimal cut-off value were determined by multiple logistic regression analyses and receiver operating characteristic (ROC) curve analysis. Results: There were no significant differences in IVIG resistance among the 4 groups (p = 0.335). The sensitivity analysis also confirmed no difference in the IVIG resistance between those who started the initial IVIG ≤ day 7 of illness and those who received IVIG >day 7 of illness (p = 0.761). In addition, patients who received IVIG administration more than 7 days from the onset had a higher proportion of coronary artery abnormalities (p = 0.034) and longer length of hospitalization (p = 0.033) than those who started IVIG administration less than 7 days. The optimal cut-off value of initial IVIG administration time for predicting IVIG resistance was >7 days, with a sensitivity of 75.25% and specificity of 82.41%. Conclusions: IVIG therapy within 7 days of illness is found to be more effective for reducing the risk of coronary artery abnormalities than those who received IVIG >day 7 of illness. IVIG treatment within the 7 days of illness seems to be the optimal therapeutic window of IVIG. However, further prospective studies with long-term follow-up are required.

Abstract A novel kiwifruit wine (KW) fermented by Aspergillus niger and Aspergillus oryzae was developed with elegant flavor and poor alcoholic strength. The effects of natural aging, microwave and ultrasonic treatment on the quality of KW were investigated. A total of 61 aroma components were detected in the KW fermented by Aspergillus niger and Aspergillus oryzae. The results showed that microwave and ultrasonic treatments could promote the maturation of KW and increase the aroma components of KW. The variety of flavor components increased with a longer storage time. Combined with the taste evaluation analysis. The esters, alcohols, acids, and aldehydes in ultrasonic-aged wines were in dynamic balance and harmony with each other. The wine was soft and mellow, making the kiwi wine more typical.

Abstract To study the stability of meat color in the post-slaughter storage process of Qinchuan cattle, three different bovine muscles, including longissimus dorsi (LD), knee round (KR) and psoas major (PM) muscles of Qinchuan cattle, were selected as research objects to determine the changes in meat color, myoglobin (Mb) relative content, pH, oxygen consumption rate (OCR), total iron, heme iron (HI) and other contents during storage. With the prolongation of the storage time, the relative content of oxymyoglobin (OxyMb) decreased, the relative content of metmyoglobin (MetMb) gradually increased, and muscle browning was due to the increase of a* value and hue value; Among them, HI and non-heme iron (NHI) reduced the stability of meat color by accelerating lipid oxidation, which was consistent with the results of Mb content and meat color index determining meat color stability. Therefore, the total iron content in muscles can also be used as an indicator of meat color stability.

Abstract The effects of irradiation, ultrahigh pressure and ultraviolet combined coating (UV-coating) on physicochemical, microbial, sensory and volatile flavor compounds of low salt sliced bacon under their optimal sterilization conditions were investigated to explore the most suitable treatment for this product. The results indicated that the sterilization effect of irradiation and ultrahigh pressure was better than that of UV-coating treatment, and the nitrite content of the three treatments was far lower than the Chinese standard limit. The effect of irradiation treatment on the structure of sliced bacon was considered to be the lowest, but it promoted fat oxidation and the formation of sulfur compounds, which in turn affected the flavor. The ultrahigh pressure treatment could improve the water-holding capability and taste feeling, meanwhile remain the color as well as the composition and relative content of the main aromatic compounds such as aldehydes, phenols and hydrocarbons closest to blank group. UV-coating treatment could significantly increase moisture content, block oxygen and raise color, while its sterilization effect was poor and the sour was heavier, easily to affect the edible quality of the product. Therefore, the ultrahigh pressure process was considered as the best according to the sterilization ability and flavor quality. UVcoating UV (UV-coating physicochemical microbial product limit lowest waterholding water holding feeling aldehydes group heavier Therefore

Abstract Based on the theory of single-phase elastic medium and unsaturated porous medium, the vibration isolation effect of composite multilayer wave impeding block (WIB) in the unsaturated ground under an underground dynamic load is investigated. The results show that the best vibration isolation effect can be obtained by designing the wave impedance ratio between the composite multilayer WIB and unsaturated ground. The composite multilayer WIB improves the vibration-damping bandwidth compared with the homogeneous WIB. The vibration isolation effect is better the closer the embedded depth of the composite multilayer WIB is to the vibration source, and its vibration isolation effect increases significantly with the increase of thickness, but when the thickness of the WIB exceeds a certain critical thickness, its vibration isolation effect decreases with the increase of thickness. Soil saturation has a significant effect on the vibration isolation effect of composite multilayer WIB in the unsaturated ground, and the composite multilayer WIB can achieve a better vibration isolation effect at low saturation. singlephase single phase (WIB investigated vibrationdamping damping source

Abstract Objectives: this study aimed to evaluate the relationship of Nutritional Risk Screening 2002 (NRS2002) and in-hospital major adverse cardiac events (MACE) in patients with severe heart failure. Methods: an observational study was conducted at the emergency intensive care units (EICU) of Shandong University Qilu Hospital from January 2017 to December 2019. Nutritional screening and assessment were performed at the time of admission to hospital with the NRS2002. Results: of the 209 patients included, 16 cases (7.66 %) were not at nutritional risk, and 193 cases (92.34 %) were at risk. Among them, 12 cases (5.74 %) were malnourished, 38 cases (18.18 %) were at high nutritional risk, and 115 cases (55.02 %) were overweight and obese. The differences in prealbumin (PA) and N-terminal B-type natriuretic peptide precursor (NT-proBNP) between the 2 groups were statistically signific ant (p < 0.05). A total of 134 cases (64.12 %) received nutrition treatment support, of which 39 cases (29.10 %) received enteral nutrition (EN), 77 cases (57.46 %) parenteral nutrition, and 18 cases (13.43 %) enteral nutrition combined with parenteral nutrition (EN + SPN) support treatment. In all, 31 cases (54.39 %) reached 100 % of the target dose. Patients in the EN and EN + SPN groups had 37 MACE (64.91 %) and 31 enteral nutrition complications (54.39 %), with differences between the 3 groups being statistically significant (p < 0.05). Conclusion: the nutritional risk of patients with severe heart failure is high, and age and heart function are positively correlated with nutritional risk. The complications rate of patients with high nutritional risk is significantly higher than in those with low risk; the higher the nutritional risk, the higher the hospital mortality rate — that is, nutritional risk affects disease outcome.

Entre ellos, 12 casos (5,74 %) estaban desnutridos, 38 casos (18,18 %) tenían un alto riesgo nutricional y 115 casos (55,02 %) tenían sobrepeso u obesidad. Las diferencias de prealbúmina (PA) y precursor del péptido natriurético de tipo B N-terminal (NT-proBNP) entre los 2 grupos fueron estadísticamente significativas (p < 0,05). En total, 134 casos (64,12 %) recibieron soporte de tratamiento nutricional, de los que 39 casos (29,10 %) recibieron nutrición enteral (NE), 77 casos (57,46 %) nutrición parenteral y 18 casos (13,43 %) nutrición enteral combinada con nutrición parenteral (NE + SPN) como tratamiento de apoyo. Treinta y un casos (54,39 %) alcanzaron la dosis objetivo al 100 %. Los pacientes de los grupos EN y EN + SPN tuvieron 37 MACE (64,91 %) y 31 complicaciones de la nutrición enteral (54,39 %), siendo la diferencia entre los 3 grupos estadísticamente significativa (p < 0,05). Conclusiones: el riesgo nutricional de los pacientes con insuficiencia cardíaca grave es alto; la edad y la función cardiaca se correlacionan positivamente con el riesgo nutricional. La complicación de los pacientes con alto riesgo nutricional es significativamente mayor que la de los de bajo riesgo; cuanto mayor es el riesgo nutricional, mayor es la tasa de mortalidad hospitalaria, es decir, el riesgo nutricional afecta el resultado de la enfermedad.

SUMMARY OBJECTIVE: This study aimed to develop and validate a practical nomogram to predict the occurrence of post-traumatic hydrocephalus in patients who have undergone decompressive craniectomy for traumatic brain injury. METHODS: A total of 516 cases were enrolled and divided into the training (n=364) and validation (n=152) cohorts. Optimal predictors were selected through least absolute shrinkage and selection operator regression analysis of the training cohort then used to develop a nomogram. Receiver operating characteristic, calibration plot, and decision curve analysis, respectively, were used to evaluate the discrimination, fitting performance, and clinical utility of the resulting nomogram in the validation cohort. RESULTS: Preoperative subarachnoid hemorrhage Fisher grade, type of decompressive craniectomy, transcalvarial herniation volume, subdural hygroma, and functional outcome were all identified as predictors and included in the predicting model. The nomogram exhibited good discrimination in the validation cohort and had an area under the receiver operating characteristic curve of 0.80 (95%CI 0.72–0.88). The calibration plot demonstrated goodness-of-fit between the nomogram’s prediction and actual observation in the validation cohort. Finally, decision curve analysis indicated significant clinical adaptability. CONCLUSION: The present study developed and validated a model to predict post-traumatic hydrocephalus. The nomogram that had good discrimination, calibration, and clinical practicality can be useful for screening patients at a high risk of post-traumatic hydrocephalus. The nomogram can also be used in clinical practice to develop better therapeutic strategies.

Abstract Fluoroquinolones are an important class of antimicrobial agents to manage infectious diseases. However, knowledge about how host bile acids are modified by fluoroquinolones is limited. We investigated and compared the impact of fluoroquinolones on circulating bile acid profiles and gut microbiota from in vivo studies. We administered ciprofloxacin (100 mg/kg/day) or moxifloxacin (40 mg/kg/day) orally to male Wistar rats for seven days. Fifteen bile acids (BAs) from the serum and large intestine were quantified by HPLC-MS/MS. The diversity of gut microbiota after ciprofloxacin and moxifloxacin treatment was analyzed using high-throughput, next-generation sequencing technology. The two fluoroquinolone-treated groups had different BA profiles. Ciprofloxacin significantly reduced the hydrophobicity index of the BA pool, reduced secondary BAs, and increased taurine-conjugated primary BAs in both the serum and large intestine as compared with moxifloxacin. Besides, ciprofloxacin treatment altered intestinal microbiota with a remarkable increase in Firmicutes to Bacteroidetes ratio, while moxifloxacin exerted no effect. What we found suggests that different fluoroquinolones have a distinct effect on the host BAs metabolism and intestinal bacteria, and therefore provide guidance on the selection of fluoroquinolones to treat infectious diseases.
