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.

Abstract Objectives Research has demonstrated that obesity may be associated with rheumatoid arthritis (RA). In addition, gut microbiota and its metabolites contribute to the occurrence and development of RA and obesity. However, the mechanism by which obesity affects RA remains unclear. In this study, we aimed to investigate whether gut microbiota and their metabolites alter the effects of high fat diet (HFD) on the severity of collagen-induced arthritis (CIA) in mice. Methods Briefly, mice were divided into normal group (N), CIA model group (C), HFD group (T), and HFD CIA group (CT). Hematoxylin and Eosin staining(HE) and Safranin O-fast green staining were conducted, and levels of blood lipid and inflammatory cytokines were measured. 16S rDNA sequencing technique and liquid chromatography-mass spectrometry (LC-MS)-based metabolomics were performed to explore changes in the microbiota structure to further reveal the pathomechanism of HFD on CIA. Results HFD aggravated the severity of CIA in mice. The CT group had the highest proportion of microbial abundance ofBlautia, Oscillibacter, Ruminiclostridium-9, andLachnospiraceaeUCG 006 at the genus level, but had a lower proportion of Alistipes. Additionally, the fecal metabolic phenotype of the combined CT group shows significant changes, with differential metabolites enriched in 9 metabolic pathways, including primary bile acid biosynthesis, arginine biosynthesis, sphingolipid metabolism, purine metabolism, linoleic acid metabolism, oxytocin signaling pathway, aminoacyl-tRNA biosynthesis, the pentose phosphate pathway, and sphingolipid signaling pathway. Correlation analysis revealed that some of the altered gut microbiota genera were strongly correlated with changes in fecal metabolites, total cholesterol (TC), triglyceride (TG), and inflammatory cytokine levels. Conclusions This study shows that HFD may aggravate inflammatory reaction in CIA mice by altering the gut microbiota and metabolic pathways. RA. .

Abstract Background Understanding the epidemiology of Streptococcus pneumoniae (S. pneumoniae) isolates is important for pneumonia treatment and prevention. This research aimed to explore the epidemiological characteristics of S. pneumoniae isolated from pediatric inpatients and outpatients during the same period. Methods S. pneumoniae were isolated from unsterile samples of inpatients and outpatients younger than five years old between March 2013 and February 2014. The serotypes were determined using diagnostic pneumococcal antisera. The resistance of each strain to 13 antibiotics was tested using either the E-test or the disc diffusion method. The Sequence Types (STs) were analyzed via Multilocus Sequence Typing (MLST). Results The dominant serotypes obtained from inpatients were 19F (32.9 %), 19A (20.7 %), 23F (10.7 %), 6A (10.0 %), and 14 (8.6 %), while those from outpatients were 19F (13.6 %), 23F (12.9 %), 6A (10.0 %), 6B (10.0 %), and 19A (7.9 %). The coverage rates of 13-valent Pneumococcal Conjugate Vaccine (PCV) formulations were high in both groups. The nonsusceptibility to penicillin, cefuroxime, imipenem, erythromycin, and trimethoprim-sulfamethoxazole among the inpatient isolates was 7.1 %, 92.8 %, 65.7 %, 100 %, and 85.0 %, respectively, while that among the outpatient isolates was 0.7 %, 50.0 %, 38.6 %, 96.4 %, and 65.7 %, respectively. There were 45 and 81 STs detected from the pneumococci isolated from inpatients and outpatients, respectively. CC271 was common among both inpatients and outpatients (43.6 % and 14.3 %). Conclusions Pneumococcal vaccine-related serotypes are prevalent among both inpatients and outpatients, especially among inpatients, who exhibit more severe antibiotic resistance. Therefore, universal immunization with PCV13 would decrease the hospitalization rate due to S. pneumoniae and the antibiotic resistance rate of S. pneumoniae.

ABSTRACT: Bovine viral diarrhea virus (BVDV) can cause acute and persistent infections in cattle, resulting in significant economic losses to the livestock industry each year. Targeted antiviral therapy is an effective strategy. This study was based on network pharmacology, molecular docking techniques and in vitro studies to investigate quercetin’s mechanism in treating bovine viral diarrhea/mucosal disease (BVD-MD). The network topology analysis was carried out using Cytoscape 3.9.0 software to construct the network of “Chinese medicine ingredients-target-diseases”. Protein interactions were explored and analyzed using the String system (PPI). GO and KEGG pathway analysis of the intersected targets was performed using Bioconductor software. The molecular docking and molecular dynamics simulation methods were used to reveal the degree of binding of quercetin to key target genes. Western blot and indirect immunofluorescence were used to characterize the antiviral effects of quercetin. This study utilized network pharmacological analysis, identifying 22 targets associated with BVD-MD. The results of the KEGG pathway showed that quercetin was closely related to Ras and MAPK signaling pathways of BVD-MD. Molecular docking results showed that SRC, NS5B, NOX4 and XDH were the key targets of quercetin in the treatment of BVD-MD. Through network pharmacology, molecular docking and in vitro experiments, quercetin was demonstrated to combat bovine viral diarrhea mucosal disease through key targets of SRC, MAPK1, GSK3B, NS5B and E2. Molecular dynamics analysis showed that quercetin exhibited complex stability with NS5B. This study provides a theoretical and experimental basis for quercetin treatment of BVD-MD and later drug development.

Resumo Fundamento A estratificação de risco precoce com biomarcadores simples é essencial em pacientes com infarto do miocárdio sem supradesnivelamento do segmento ST (IAMSSST). Objetivo Este estudo tem o objetivo de avaliar a associação entre nível de big endotelina-1 plasmática (ET-1) e o escore SYNTAX (SS) em pacientes com IAMSSST. Métodos Foram recrutados 766 pacientes com IAMSSST que passaram por angiografia coronária. Os pacientes foram divididos em três grupos: SS baixo (≤22), SS intermediário (23-32), e SS alto (>32). A correlação de Spearman, o ajuste de curva suave, a regressão logística, e a análise de curva característica de operação do receptor (ROC) foram realizados para avaliar a associação entre o nível de big ET-1 plasmática e o SS. Um p-valor <0.05 foi considerado estatisticamente significativo. Resultados Foi identificada uma correlação significativa entre a big ET-1 e o SS (r=0,378, p<0,001). A curva suavizada indicou uma correlação positiva entre o nível de big ET-1 plasmática e o SS. A análise de curva ROC demonstrou que a área sob a curva foi de 0,695 (0,661-0,727) e o ponto de corte ideal do nível de big ET-1 plasmática foi de 0,35 pmol/l. A regressão logística demonstrou que a big ET-1 elevada era um preditor independente de SS intermediário a alto em pacientes com IAMSSST, seja como variável contínua [RC (IC 95%: 1,110 (1,053-1,170), p<0,001] ou como variável categórica [RC (IC 95%: 2,962 (2,073-4,233), p<0,001]. Conclusão Em pacientes com IAMSSST, o nível de big ET-1 plasmática estava significativamente correlacionado ao SS. O nível de big ET-1 plasmática elevado foi um preditor independente para SS intermediário a alto. .

Abstract Background Early risk stratification with simple biomarkers is essential in patients with non-ST segment-elevation myocardial infarction (NSTEMI). Objective This study aimed to evaluate the association between plasma big endothelin-1 (ET-1) level and the SYNTAX score (SS) in patients with NSTEMI. Methods A total of 766 patients with NSTEMI undergoing coronary angiography were recruited. Patients were divided into three groups: low SS (≤22), intermediate SS (23-32), and high SS (>32). Spearman correlation, smooth curve fitting, logistic regression, and receiver operating characteristic (ROC) curve analysis were performed to evaluate the association between plasma big ET-1 level and the SS. A p-value <0.05 was considered statistically significant. Results There was a significant correlation between the big ET-1 and the SS (r=0.378, p<0.001). The smoothing curve indicated a positive correlation between the plasma big ET-1 level and the SS. The ROC curve analysis showed that the area under the curve was 0.695 (0.661-0.727) and the optimal cutoff of plasma big ET-1 level was 0.35pmol/l. Logistic regression showed that elevated big ET-1 was an independent predictor of intermediate-high SS in patients with NSTEMI, whether entered as a continuous variable [OR (95% CI): 1.110 (1.053-1.170), p<0.001] or as a categorical variable [OR (95% CI): 2.962 (2.073-4.233), p<0.001]. Conclusion In patients with NSTEMI, the plasma big ET-1 level was significantly correlated with the SS.

ABSTRACT Purpose: To evaluate the impact of one-time high load exercise on skeletal muscle injury and analysis its mechanism in different genders. Methods: Twenty-four male and 24 female rats were divided randomly into four groups respectively: control, 0 h, 6 h, and 24 h after exercise. The activities of creatine kinase (CK), lactate dehydrogenase (LDH), and myohemoglobin (MYO) in serum, the expression level of oxidative stress markers, mitochondrial respiratory chain complex enzyme, and the apoptosis related protein in quadriceps were detected. Results: The results showed that the activities of CK, LDH and MYO in serum increased immediately after exercise and restored faster in female rats. More obvious structural disorder and apoptosis in male rats were showed. Malondialdehyde (MDA) and superoxide dismutase (SOD) were increased while catalase (CAT) and glutathione (GSH) were decreased in male rats. SOD, CAT and GSH were increased in female rats. Mitochondrial complex enzyme activity was decreased in males and increased in females. Conclusions: The skeletal muscle injury in both genders of rat could be induced by one-time high load exercise due to the mitochondrial respiratory enzyme dysfunction and oxidative stress, which was relatively mild and recovered quicker in female rats.

Abstract To explore the favourable functions of polysaccharide from Spirulina platensis (PSP) on sepsis-originated acute lung injury, together with the corresponding mechanisms. 60 male SD rats were randomly separated into sham, sepsis, and sepsis+PSP group with 20 rats in each group. Sepsis rat model was constructed by cecal ligation and puncture (CLP). The mortality and sepsis-related symptoms were used to judge the model success. CLP successfully established the sepsis-caused acute lung injury rat model. In sepsis rats, systemic inflammation and pulmonary inflammation, as well as endocan protein level were increased. PSP treatment improved sepsis-induced acute lung injury and systemic inflammation, and reduced the endocan protein level. Lung injury biomarkers were positively correlated with serum pro-inflammatory factors/serum endocan protein, while serum pro-inflammatory factors were positively associated with serum endocan level. PSP ameliorates acute lung injury via relieving inflammatory response and down-regulating endocan expression in sepsis rat.

ABSTRACT Background: Dragon′s blood is a well-known traditional Chinese medicine, isolated mainly from the trunks of Dracaena trees. Overexploitation of the Dracaena resource has resulted in this plant becoming endangered. This work aimed to assess the potential to use various tissues of the Dracaena cochinchinensis tree, such as leaves and roots, to produce dragon′s blood. Results: We found that many dragon′s blood components accumulated in the bark of trunk and roots of D. cochinchinensis under natural conditions. In addition, small amounts of loureirin A were detected in leaves, suggesting that the leaves could be a potential source of dragon′s blood. Real-time quantitative PCR analysis showed that most of the genes tested in this study, which encoded enzymes involved in the biosynthesis of dragon′s blood flavonoids, were highly expressed in the bark of roots and trunk. Conclusion: We confirmed that the bark of roots and trunk of D. cochinchinensis tree were the main tissues for the synthesis and storage of dragon′s blood under natural conditions. This study demonstrated the potential to extract dragon′s blood from the roots that have been abandoned due to mining difficulties without destroying the tree, a process which would be beneficial to the protection of the endangered wild D. cochinchinensis tree populations.

ABSTRACT Soil deterioration, yield decline and soil microbial activity reduction caused by banana (Musa × paradisiaca L.) monoculture is threatening the sustainability of banana production in China. Therefore, it is necessary to study the benefits of rotation on soil quality. This study aimed to assess the effects of rotation and tillage on soil properties in a banana plantation for 25 yr. Treatments consisted of three rotation methods (banana-pineapple, BA; banana-cowpea, BP; banana-rice, BR) and banana monoculture (CK) combined with two tillage intensities (no-tillage, NT; conventional tillage, CT). Soil samples were taken at depth of 0-40 cm in 2019-2020. In comparison with CK, BA and BR increased soil moisture, pH, total organic C and available P, but decreased soil bulk density. Microbial biomass C and N at booting stage were 46.1% and 39.2% higher in BA and BR than those in CK. Urease, dehydrogenase and β-glucosidase obtained a mean of 34.1% increase in BP and 23.8% increase in BR compared with BA. Higher total N, NO3-N, available K and macro aggregate were showed in NT compared with CT, whereas porosity was 24.8% lower in NT than in CT. CO2, N2O and CH4 emissions were in average around between one third and two fifth lower in no-tillage compared with conventional tillage. In general, rotations combined with no-tillage led to a positive effect on soil quality, as evidenced by increase of soil moisture, total N, microbial biomass C and urease and accompanying increase in banana yield. In order to sustain higher productivity, application of rotation and no-tillage is of considerable importance.

RESUMO Pholiota adiposa é um cogumelo com excelentes propriedades nutricionais e medicinais. No entanto, o rendimento do corpo de frutificação deste é baixo e o potencial de cultivo comercial deste fungo é limitado. 279 linhagens cruzadas foram obtidas pelo cruzamento mono-mono de linhagens monocarióticas derivadas de P. adiposa HS5 e HS4. Enzimas ligninolíticas e taxas de crescimento micelial foram utilizadas como marcadores para a triagem das linhagens cruzadas, e 18 linhagens foram seleccionadas para análise posterior. A linhagem cruzada A10B4 apresentou o maior rendimento (ie 165,91 ± 12,56 g por sacola), o qual 31,34 g e, 74,48 g a mais do que as linhagens HS5 e HS4, respetivamente. O tempo de colonização micelial de A10B4 foi 25,18 ± 1,33 d, sendo 5,64 d menor que HS5. A10B4 foi caracterizado, por marcadores moleculares de repetição de sequência inter-simples. Foram observadas diferenças nos produtos de PCR de linhagens parentais e cruzadas. Portanto, a linhagem híbrida recém-desenvolvida A10B4 (Renominada P. adiposa HS54), exibindo alto rendimento, pode ser adequada para cultivo comercial.

ABSTRACT Pholiota adiposa is a mushroom with excellent nutritional and medicinal properties. However, fruiting body yields are low, and the commercial cultivation potential of this fungus is limited. Here, 279 crossbred strains were obtained by the mono-mono crossing of monokaryotic strains derived from P. adiposa HS5 and HS4. Laccase enzymes and mycelial growth rates were used as markers to screen the crossbred strains, and 18 strains were selected for further analysis. Crossbred strain A10B4 displayed the highest yield (i.e. 165.91 ± 12.56 g per bag), which was 31.34 g and 74.48 g more than that of strains HS5 and HS4, respectively. The mycelial colonization time of A10B4 was 25.18 ± 1.33 d, which was 5.64 d shorter than that of HS5. A10B4 was characterized by inter-simple sequence repeat molecular markers. Differences in PCR products from parental and crossbred strains were observed. Therefore, the newly developed hybrid strain A10B4, named P. adiposa HS54 exhibiting high yield, might be suitable for commercial cultivation.

SUMMARY: To reveal the regular patterns of water transport in fruit-bearing shoots of walnut (Juglans regia), water transport pathways for various organs were observed using dye-tracing technique; water potential, water status and water transport rate were determined for each of these organs. Water potential in the pedicel, petiole, lateral shoot and main shoot was -2.59, -2.85, -1.68 and -0.37 MPa, respectively. Significant differences were noted among various organs in terms of water status. The ratio of bound water to free water in the petiole was the highest (1.93 RBC), followed by the main shoot, lateral shoot and pedicel. Water transport speed in the petiole was the fastest (3.13 cm/min), followed by the lateral shoot, pedicel and main shoot. However, the water transport rate of the main shoot was the highest, and higher than the sum of the other three organs. The xylem in the petiole was separated from the main shoot; at the top of the main shoot, the xylem was divided into two parts, one of which was connected to the xylem of the pedicel and the other to the lateral shoot. During the shell-hardening period of fruits, the dye was found at the edge of the fruit vascular bundle, although, it was not at the central vascular bundle. No dye was found in the main and accessory buds, instead, only a small part of the xylem was dyed between the accessory bud and the main shoot. Water transport pathways were different for various organs. Thus, the transport and distribution of water in various organs was affected by their water potential, tissue structure and water requirement.

RESUMEN: Para revelar pautas regulares de transporte de agua en brotes frutales de nogal (Juglans regia), se observaron vías de transporte de agua de diversos órganos mediante rastreo de tintes; se determinó: potencial hídrico, estado del agua y tasa de transporte de agua de cada órgano. El potencial hídrico en el pedicelo, peciolo, brote lateral y brote principal fue de -2,59, -2,85, -1,68 y -0,37 MPa, respectivamente. El estado del agua mostró diferencias significativas entre los órganos. La relación entre el agua ligada y el agua libre en el pecíolo fue la mayor (1,93 RBC), seguida por: brote principal, brote lateral y pedicelo. La velocidad de transporte de agua en el pecíolo fue la mayor (3,13 cm/min), seguida del brote lateral, pedicelo y brote principal. Pero la tasa de transporte de agua del brote principal fue la mayor y más alta que la suma de los otros tres órganos. El xilema del peciolo estuvo separado del brote principal; en su parte superior estuvo conectado al xilema del pedicelo y al brote lateral. Durante el período de endurecimiento de la cáscara del fruto, el colorante estuvo en el borde del haz vascular del fruto, pero no en el haz vascular central. No se encontró colorante en yemas principales ni accesorias, en cambio, solo se tiñó una pequeña parte del xilema entre la yema accesoria y el brote principal. Las vías de transporte de agua fueron diferentes para los distintos órganos. El transporte y distribución del agua en varios órganos fueron afectados por su potencial hídrico, la estructura de los tejidos y las necesidades de agua.

Abstract This study aimed to investigate the potential of a novel preparation strategy for glycosylated hydrolysate by liquid fermentation in order to provide a high-quality glycosylated hydrolysate. Protein solubility, surface hydrophobicity and antioxidant activity were evaluated. The results of Fourier transform infrared spectra demonstrated the occurrence of glycosylation reaction. The results of Fluorescence emission spectroscope revealed the decrease of tertiary conformation stability. Circular dichroism spectra revealed significant decrease in α-helix and increase in β-sheet and random coil by glycosylation reaction. In comparison with zein hydrolysate, glycosylated hydrolysate had lower surface hydrophobicity but higher in solubility and in vitro digestibility due to glycosylation. Glycosylated hydrolysate presented higher ABTS (2,2'-Azinobis [3-ethylbenzothiazoline-6-sulfonic acid]-diammonium salt) and superoxide radicals scavenging activities as well as Cu2+ chelating capacity. It is concluded that the glycosylation confer an open structure and modified properties of zein, and glycosylated hydrolysate is a potential ingredient with better hydration and antioxidant activities than zein hydrolysate.

SUMMARY BACKGROUND An association between increased serum ferritin levels and acute myocardial infarction (AMI) remains controversial. The purpose of this meta-analysis is to confirm the association between increased serum ferritin levels and AMI. METHODS We searched PubMed and China National Knowledge Infrastructure (CNKI) for relevant articles that assessed the association between serum ferritin and acute myocardial infarction using terms that included serum ferritin and acute myocardial infarction up to February 13, 2019. RESULTS A total of 11 studies were identified for analysis. All pooled analysis was based on a random-effects models. The variance was exhibited using a forest plot, and the heterogeneity among studies was examined using the I2 index, the publication bias was evaluated using a funnel plot. The pooled standard mean difference of ferritin levels between AMI and controls was 0.78 (95%CI,0.68-0.88). CONCLUSION The results of this meta-analysis demonstrate that serum ferritin in acute myocardial infarction patients is higher than that of healthy controls.

Abstract Cordyceps militaris 202 is a potential fungus for biotransformation zein, due to its various proteases, high tolerance and viability in nature. In this article, single factor experiment and response surface methodology were applied to optimize the liquid fermentation conditions and improve the ability of biotransformation zein. The optimized fermentation conditions were as follows: inoculum concentration of 19%, volume of liquor of 130 mL/500 mL and pH of 4.7. Under this condition, the degree of hydrolysis (DH) was 27.31%. The zein hydrolysates from fungi fermentation maintained a high thermal stability. Compared to the original zein, the zein hydrolysates were found to have high solubility, which most likely results in improved foaming and emulsifying properties. Overall, this research demonstrates that hydrolysis of zein by C. militaris 202 is a potential method for improving the functional properties of zein, and the zein hydrolysates can be used as functional ingredients with an increased antioxidant effect in both food and non-food applications.

Icariin has been reported to possess high anticancer activity. Colon carcinoma is one of the leading causes of cancer-related mortality worldwide. Here, the anticancer activity of icariin against HCT116 colon carcinoma cells and the possible underlying mechanism were studied. The trypan blue staining assay, wound healing assay, clonogenic assay, CCK-8 assay, and Annexin V-FITC/PI double staining method were carried out to determine the changes of HCT116 cell growth and migration. mRNA and protein expressions were determined by quantitative real-time PCR and western blot, respectively. Moreover, small interfering RNA (siRNA) plasmid was used to examine the role of p53 in icariin-induced apoptosis in HCT116 cells. Icariin significantly suppressed colon carcinoma HCT116 cells by decreasing migration and viability, and simultaneously promoting apoptosis. Icariin exerted the anti-tumor effect in a dose-dependent manner by up-regulating p53. During treatment of icariin, p-p53, p21, and Bax levels increased, and Bcl-2 level decreased. Short time treatment with icariin induced DNA damage in HCT116 cells. Furthermore, the cytotoxicity of icariin was decreased after p53 knockdown or by using caspase inhibitors. p53 was involved in activities of caspase-9 and caspase-3. Icariin repressed colon carcinoma cell line HCT116 by enhancing p53 expression and activating p53 functions possibly through Bcl-2/Bax imbalance and caspase-9 and -3 regulation. Icariin treatment also induced DNA damage in HCT116 cells.
