The probiotic composition provided by this invention includes at least two of the following: prebiotics, vitamin K, and zinc, as well as *Bifidobacterium longum* subsp. infantis i18. The probiotic composition provided by this invention can not only effectively promote the growth and development of premature mice, but also optimize the intestinal flora structure and promote intestinal development in premature infants by reducing the abundance of harmful bacteria and increasing the relative abundance of beneficial bacteria; simultaneously, it can downregulate the levels of pro-inflammatory factors TNF-α and IL-6, reducing intestinal inflammation and lowering the risk of necrotizing enterocolitis in premature infants. This invention can be applied to the preparation of products that improve the intestinal flora of premature infants, promote their growth, or prevent intestinal inflammation.

This invention discloses a strain of *Bacillus belyceae* with broad-spectrum antibacterial activity and its application in the prevention and treatment of necrotic enteritis in poultry. The *Bacillus belyceae* strain provided by this invention (… Bacillus from Velez The genome of strain GDG25CB056 is approximately 3.91 Mb in size, contains no virulence factors, and is rich in gene clusters encoding non-ribosomal peptides and polyketide synthases. Studies have confirmed that this strain exhibits significant growth advantages, strong tolerance to high temperatures, gastric acid, and bile salts, which facilitates intestinal colonization. It can produce siderophores and various enzymes, and has overcome the technical bottleneck of a narrow antibacterial spectrum, possessing broad-spectrum antibacterial activity, especially strong specific antagonistic activity against Clostridium perfringens. In vivo experiments have shown that this strain can significantly reduce the Clostridium perfringens load in the cecum of chicks with necrotizing enterocolitis, alleviate intestinal congestion and swelling, repair damaged intestinal villi, and enhance mucosal barrier function, providing a safe and efficient strain resource for the prevention and treatment of bacterial enteric diseases.

The invention relates to the field of infant food, in particular to an anti-oxidative stress composition and application thereof to improvement of neonatal necrotizing enterocolitis. The composition is prepared from the following components: neutral oligosaccharide and sialylated oligosaccharide. The neutral oligosaccharide is 3-fucosyllactose, and the sialylated oligosaccharide is 3 '-sialic acid lactose. The invention provides a composition capable of relieving neonatal necrotizing enterocolitis. Through combination of the 3-fucosyllactose and the 3 '-sialic acid lactose, related symptoms of the neonatal necrotizing enterocolitis can be improved by inhibiting a TLR4 / NF-kappa B inflammation pathway, improving cell oxidative stress, protecting cell barriers and reducing cell apoptosis, and the 3-fucosyllactose and the 3'-sialic acid lactose have important application value in the field of functional foods or formula foods.

The invention relates to the technical field of molecular biology, and provides a marker combination for diagnosing neonatal necrotizing enterocolitis and application thereof. The marker combination comprises a CC chemokine ligand 20, a heparin binding epidermal growth factor, angiotensin and aldosterone. Four markers related to neonatal necrotizing enterocolitis are obtained through research and screening, whether neonatal necrotizing enterocolitis occurs or not and the severity of neonatal necrotizing enterocolitis can be effectively judged based on the markers, and the markers have high sensitivity and specificity and can be used for detecting neonatal necrotizing enterocolitis. The kit can help clinical diagnosis and prognosis of neonatal necrotizing enterocolitis.

To provide a bifunctional degrading agent for interleukin-1 receptor-related kinases and its therapeutic use. [Solution] This disclosure provides a bifunctional compound as an IRAK4 degradation agent via the ubiquitin-proteasome pathway, and a method for treating diseases modulated by IRAK4. The compounds of this disclosure or their pharmaceutical compositions are useful as therapeutic agents for treating inflammatory disorders such as rheumatoid arthritis (RA), inflammatory bowel disease (IBD), Crohn's disease, ulcerative colitis, necrotizing enterocolitis, gout, Lyme disease, arthritis, psoriasis, pelvic inflammatory disease, systemic lupus erythematosus (SLE), Sjögren's syndrome, inflammation associated with gastrointestinal infections including C. difficile, viral myocarditis, acute and chronic tissue injury, non-alcoholic steatohepatitis (NASH), alcoholic hepatitis, and renal diseases including chronic kidney disease and diabetic kidney disease.

The application discloses application of anti-myosin autoantibody in preparation of a diagnosis product for neonatal necrotizing enterocolitis. The application determines that IgG and IgM type anti-myosin autoantibody in peripheral blood of a child with neonatal necrotizing enterocolitis (NEC) is significantly increased in early stage of the disease; the application finds that the anti-myosin autoantibody can be used as an early prediction and diagnosis marker, and is used for diagnosis of NEC; the marker has high diagnosis efficiency for early NEC, and provides an effective basis for early prediction and diagnosis of NEC.

The invention belongs to the technical field of biological medicines, and relates to application of nicotinic acid in preparation of a medicine for preventing and treating neonatal necrotizing enterocolitis. In-vivo experiments prove that the nicotinic acid can enhance the immunosuppression function of myeloid-derived suppressor cells, so that the excessive inflammatory reaction of intestinal tracts of neonatal necrotizing enterocolitis model mice is inhibited, and necrotizing enterocolitis is relieved; nicotinic acid is a vitamin necessary for a human body, the safety advantage of nicotinic acid is far better than that of a brand new chemical synthesis medicine, and the risk and cost of clinical transformation are reduced.

Disclosed is a method for monitoring and evaluation of bowel health in premature newborns. The method involves collecting stool / fecal samples from premature newborns / babies and processing the sample using microbiomics, automated cell counting, flowcytometry, and RT PCR analysis using specific gene signature or RNA transcriptomics analysis to determine risk of necrotizing enterocolitis. The method allows evaluation and tracking of gut health without needing to draw a blood test and is a non-invasive method. The method diagnoses and prevents bowel inflammation, infection and necrotizing enterocolitis (NEC) that facilitates initiation of prompt therapy to limit morbidity and mortality in premature babies. The method facilitates early management of signs of NEC thereby helping to save lives of premature babies and infants having low birth weight.

The invention provides an application of ribosome small subunit protein RPS29 in diagnosis of neonatal necrotizing enterocolitis. Research finds that the expression level of the RPS29 protein in a biological sample of a neonatal necrotizing enterocolitis patient is remarkably reduced compared with that of a control neonatal. A further ROC curve analysis result shows that the RPS29 protein can be used as a specific detection marker of the neonatal necrotizing enterocolitis for assisting diagnosis of the neonatal necrotizing enterocolitis, and early diagnosis and early treatment of the neonatal necrotizing enterocolitis can be realized.

Disclosed herein are methods, devices, and systems for accurately detecting and / or diagnosing a child having or at risk of developing necrotizing enterocolitis (NEC).
