RESUMEN
ObjectiveTo observe the clinical efficacy of modified Yigongsan combined with multi-enzyme tablets and bifidobacterium triple live powder on infantile anorexia with spleen-stomach Qi deficiency syndrome. MethodA total of 112 infantile patients anorexia with spleen-stomach Qi deficiency syndrome treated at Hebei Provincial Hospital of Traditional Chinese Medicine from January 2022 to June 2023 were enrolled and divided into a control group and an observation group， with 56 cases in each group， according to a random number table. Children in the control group were treated with multi-enzyme tablets and Bifidobacterium triple live powder， while those in the observation group were treated with modified Yigongsan in addition to the treatment in the control group. During the study， one case dropped out in the control group and two cases dropped out in the observation group. The clinical efficacy of the two groups of children was compared， including changes in traditional Chinese medicine （TCM） syndrome scores （main symptoms， secondary symptoms， tongue， and pulse）， time to restore normal food intake， and increase in body weight. Changes in calcium， iron， zinc levels， hemoglobin， and albumin levels before and after treatment， as well as changes in gastrointestinal hormones such as gastrin and motilin， vasoactive intestinal peptide， somatostatin， neuropeptide Y， orexin， and leptin， were observed. The occurrence of adverse reactions in the two groups of children during the study was also recorded. ResultThe total effective rate of children in the control group after treatment was 85.19% （46/54）， while that in the observation group was 98.15% （53/54） （χ2 =5.939， P<0.05）. Compared with the control group， the time for food intake to return to normal in the observation group was shorter， and the increase in body weight was greater （P<0.05）. Compared with the results before treatment， the TCM syndrome scores （main symptoms， secondary symptoms， tongue， and pulse） in both groups of children significantly decreased， while the levels of calcium， iron， zinc， hemoglobin， albumin， gastrin， motilin， neuropeptide Y， and orexin increased， and the levels of vasoactive intestinal peptide， somatostatin， and leptin decreased （P< 0.01）. Compared with the control group after treatment， the improvement in the above indicators in the observation group was more significant （P<0.01）. The incidence of adverse reactions in the two groups of children during the treatment period was similar， and the difference was not statistically significant. ConclusionModified Yigongsan combined with multi-enzyme tablets and Bifidobacterium triple live powder is highly effective in treating infantile anorexia （spleen-stomach Qi deficiency syndrome）. After treatment， symptoms of the children were improved，appetite and food intake increased， gastrointestinal function was improved， body weight increased， and adverse reactions were few， indicating that the treatment was safe and reliable.

It can significantly improve clinical symptoms, and its mechanism may be related to the regulation of intestinal microbiota and serum inflammation.
RESUMEN
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.

RESUMEN
Aims@#This study aimed to investigate the effect of exopolysaccharide (EPS) from Bifidobacterium pseudocatenulatum ATCC 27919 in Caco-2 cells on apoptotic and autophagic pathways.@*Methodology and results@#Cell viability was examined by MTS assay and it showed a significant decrease in Caco-2 cells after exposure to EPS. Microscopy imaging and morphological analyses demonstrated that EPS-exposed Caco-2 cells exhibited the main morphological characteristics of apoptosis. EPS-exposed cells showed early apoptosis and cell cycle arrest at the G2/M phase in the cell cycle and dead cell assays. qPCR suggested that mRNA expression of substantial apoptotic markers such as cleaved Caspase-3, BAX and PARP-1 were significantly increased in EPS-exposed cells. The autophagy event was demonstrated in EPS-exposed cells by the contrary mRNA expression of Beclin-1 and Bcl-2 and the detection of autophagic LC3-II protein at 24 h exposure. GRP78 mRNA expression was also increased in EPS-exposed cells, indicating the occurrence of endoplasmic reticulum (ER) stress. @*Conclusion, significance and impact of study @#Autophagy activity in EPS-exposed Caco-2 cells preceded apoptosis, suggesting it was a cytoprotective response against ER stress. Research findings set the foundation for therapeutic CRC treatments and provide insight into its regulatory processes.

Abstract This study aimed to evaluate the effect of Bifidobacterium animalis subsp. lactis (B. lactis) HN019 in drinking water on the development of apical periodontitis (AP) in rats. In total 60 animals were divided into a control group (sound teeth); Group I - regular water without AP; Group II - probiotic water without AP; Group III - regular water with AP; Group IV - probiotic water with AP. AP was induced after 3 days in the control groups and after 7, 21, and 42 days in groups III and IV. The animals were euthanized, and the mandibles were subjected to histotechnical processing. Samples were stained with hematoxylin & eosin (H&E) to identify root canal features, apical and periapical regions. Additionally, histoenzymology was performed to detect osteoclasts, immunohistochemistry was used to identify osteoclastogenesis markers, and the Brown & Brenn technique was applied for microbiological analysis. The data were analyzed using GraphPad Prism 8.0.1 with a significance level of 5%. Although no statistical differences were observed, the groups administered with probiotics showed better conditions in terms of histological aspects seen microscopically. Furthermore, there were no differences in the number of osteoclasts (p > 0.05). The RANKL marker was not found in the probiotic group at 42 days, unlike in group III.
RESUMEN
Traditionally, fermented food and beverages are prepared by adding a mixture of plant residues as a starter or source of microbes. Most of the conventional fermented foods use a local starter which contains a mixture of herbs or old ferment or otherwise cereal dust-coated tablet. In this study, we have made an attempt to prepare a rice-based fermented food with the herbal starter (0.5% w/w) of Elephantopus scaber L. rhizome, and also examined its microbial and nutrient profiles. The food product is fortified with organic acid and titratable acidity of 0.58% and also contained an excellent source of microbes (LAB and Bifidobacterium sp.). The fermented food contains significant amount of fat, protein, minerals, vitamins, oligosaccharide, unsaturated fatty acids (?3, ?6, ?7 and ?9) and a pool of free amino acids. The presence of phytochemical contents in the fermented rice was also exhibited significant effects against commercially available free radicals (DPPH, ABTS, FRAP and OH-radicals). Thus, food-grade microbes containing newly formulated fermented food would provide essential macro-and micro-nutrients to the individuals and convey the sustainability of good health. Therefore, the mentioned plant part would be used as an effective starter for aiding rice-based food products.
RESUMEN
La incidencia de enfermedades alérgicas en la infancia va en aumento, y se ha convertido en una de las principales consultas. Una posible causa es la disbiosis del microbioma intestinal, relacionada con estados inflamatorios aumentados. Debido a la necesidad de mejorar la calidad de vida, y el impacto en lo económico y en lo educativo, surgen los probióticos como tratamiento adyuvante, por lo que se pretende determinar la asociación del uso de Bifidobacterium en menores de 5 años con la modulación de la respuesta inmune en enfermedades alérgicas. El microbioma intestinal inicia su desarrollo y maduración desde la gestación, continúa en el nacimiento y termina hasta los 3 años, influenciado por factores maternos, neonatales y ambientales. La disbiosis intestinal generada por estos factores reduce la proporción de bifidobacterias, lo cual se relaciona con estados proinflamatorios. En consecuencia, estudios del uso de Bifidobacterium en niños con enfermedades alérgicas ha evidenciado mejora de síntomas y calidad de vida. Los probióticos favorecen un microbioma intestinal saludable, asociado a un estado antiinflamatorio, debido a la regulación en el balance celular Th1/Th2/T reguladoras y células asesinas naturales. Esta modulación en la respuesta inmune permite mejor control de síntomas, calidad de vida y menor incidencia de enfermedades alérgicas en la infancia
The incidence of allergic diseases in childhood is increasing, and has become one of the main queries. One possible cause is dysbiosis of the gut microbiome, related to increased inflammatory states. Due to the need to improve the quality of life, and the economic and educational impact, probiotics emerge as adjuvant treatment, so it is intended to determine the association of the use of Bifidobacterium in children under 5 years with the modulation of the immune response in allergic diseases. The intestinal microbiome begins its development and maturation from gestation, continues at birth and ends up to 3 years, influenced by maternal, neonatal and environmental factors. The intestinal dysbiosis generated by these factors reduces the proportion of bifidobacteria, which is related to proinflammatory states. Consequently, studies of the use of Bifidobacterium in children with allergic diseases have shown improvement in symptoms and quality of life. Probiotics favor a healthy intestinal microbiome, associated with an anti-inflammatory state, due to the regulation of the regulatory Th1/Th2/T cell balance and natural killer cells. This modulation in the immune response allows better control of symptoms, quality of life and lower incidence of allergic diseases in childhood

RESUMEN
Objective:To investigate the effects of Bifidobacterium animalis subsp. lactis BB-12 on hippocampal neuroinflammation and cognitive function of mice after whole brain radiotherapy. Methods:A total of sixty male C57BL/6J mice aged 7-8 weeks were randomly divided into 5 groups with 12 mice in each group: control group (Con group), probiotic group (BB-12 group), irradiation group (IR group), irradiation and Memantine group (IR+ Memantine group), irradiation and probiotic group (IR+ BB-12 group). The model of radiation-induced brain injury of mice was established by 10 Gy whole brain radiotherapy with a medical linear accelerator. Y-maze test was used to evaluate the cognitive function. The activation of microglia and astrocytes was observed by immunofluorescence staining. The expressions of inflammatory cytokines interleukin-1β (IL-1β), IL-6 and tumor necrosis factor-α (TNF-α) were detected by quantitative real-time reverse transcription polymerase chain reaction (QRT-PCR) and Western blot.Results:Y-maze test showed that, compared with Con group, the percentage of the times of reaching the novel arm in the total times of the three arms decreased significantly in the IR group ( t=5.04, P<0.05). BB-12 mitigated radiation-induced cognitive dysfunction ( t=4.72, P<0.05). Compared with Con group, the number ( t=3.05, 7.18, P<0.05) and circularity index ( t=6.23, 2.52, P<0.05) of Iba1 and GFAP positive cells were increased, the microglia and astrocytes were activated in the hippocampus of IR group, but these alterations were eliminated by BB-12. After whole brain IR, the mRNA and protein expression levels of inflammatory cytokines IL-1β, IL-6 and TNF-α in the hippocampus of mice were significantly increased compared with Con group ( tmRNA =4.10, 3.04, 4.18, P<0.05; tprotein=11.49, 7.04, 8.42, P<0.05), which were also significantly reduced by BB-12 compared with IR group ( tmRNA=4.20, 3.40, 2.84, P<0.05; tprotein=6.36, 4.03, 3.75, P<0.05). Conclusions:Bifidobacterium animalis BB-12 can suppress neuroinflammation mediated by microglia and astrocytes in the hippocampus of mice after radiotherapy and alleviates IR-induced cognitive dysfunction. Therefore, BB-12 has potential application in alleviating radiation induced brain injury.
RESUMEN
Remodeling the tumor microenvironment through reprogramming tumor-associated macrophages (TAMs) and increasing the immunogenicity of tumors via immunogenic cell death (ICD) have been emerging as promising anticancer immunotherapy strategies. However, the heterogeneous distribution of TAMs in tumor tissues and the heterogeneity of the tumor cells make the immune activation challenging. To overcome these dilemmas, a hybrid bacterium with tumor targeting and penetration, TAM polarization, and photothermal conversion capabilities is developed for improving antitumor immunotherapy in vivo. The hybrid bacteria (B.b@QDs) are prepared by loading Ag2S quantum dots (QDs) on the Bifidobacterium bifidum (B.b) through electrostatic interactions. The hybrid bacteria with hypoxia targeting ability can effectively accumulate and penetrate the tumor tissues, enabling the B.b to fully contact with the TAMs and mediate their polarization toward M1 phenotype to reverse the immunosuppressive tumor microenvironment. It also enables to overcome the intratumoral heterogeneity and obtain abundant tumor-associated antigens by coupling tumor penetration of the B.b with photothermal effect of the QDs, resulting in an enhanced immune effect. This strategy that combines B.b-triggered TAM polarization and QD-induced ICD achieved a remarkable inhibition of tumor growth in orthotopic breast cancer.
