Objective: Immunotherapeutic outcomes and clinical characteristics of claudin 18 isoform 2 positive(CLDN18.2-positive) gastric cancer(GC) vary in different clinical studies, making it difficult to optimize antiCLDN18.2 therapy. We conducted a retrospective analysis to explore the association of CLDN18.2 expression with clinicopathological characteristics and immunotherapeutic outcomes in ***: A total of 536 advanced GC patients from 2019 to 2021 in the CT041-CG4006 and CT041-ST-01clinical trials were included in the analysis. CLDN18.2 expression on ≥40% of tumor cells(2+, 40%) and CLDN18.2 expression on ≥70% of tumor cells(2+, 70%) were considered the two levels of positively expressed GC. The clinicopathological characteristics and immunotherapy outcomes of GC patients were analyzed according to CLDN18.2 expression ***: CLDN18.2 was expressed in 57.6%(cut-off: 2+, 40%) and 48.9%(cut-off: 2+, 70%) of *** death-ligand 1(PD-L1) and CLDN18.2 were co-expressed in 19.8% [combined positive score(CPS)≥1, CLDN18.2(cut-off: 2+, 40%)] and 17.2% [CPS≥5, CLDN18.2(cut-off: 2+, 70%)] of ***18.2 expression positively correlated with younger age, female sex, non-gastroesophageal junction(nonGEJ), and diffuse phenotype(P<0.001). HER2 and PD-L1 expression were significantly lower in CLDN18.2-positive GC(both P<0.05). Uterine adnexa metastasis(P<0.001) was more frequent and liver metastasis(P<0.001)was less common in CLDN18.2-positive GC. Overall survival and immunotherapy-related progression-free survival(ir PFS) were inferior in the CLDN18.2-positive ***: CLDN18.2-positive GC is associated with poor prognosis and worse immunotherapeutic outcomes. The combination of anti-CLDN18.2 therapy, anti-PD-L1/PD-1 therapy, and chemotherapy for GC requires further investigation.

Inflammatory bowel disease (IBD) influences several million people around the globe， with a high prevalence in North America and Europe. Results from the studies about host-gut microbial interactions demonstrated that gut microbiota plays a critical role in the progression of IBD， and probiotics can significantly improve microflora dysbiosis and inflammatory response caused by intestinal pathogens. However， several limitations existed for the probiotics delivered to the intestine in the free form (non-encapsulated)， such as low pH and diverse digestive enzymes in the gastrointestinal tract， etc. To overcome the problems， several probiotic delivery systems were established and verified with effects. Here， the types and applications of probiotics in animal models and clinical studies are firstly reviewed in this paper. Subsequently， various types of probiotic delivery systems are elaborated， containing the well-known microcapsules and hydrogel delivery systems， and the engineered probiotic delivery systems are also introduced. Furthermore， mechanism of action associated with probiotics are illustrated， including maintaining gut microbiota barrier balance， modulating the immune response， and alleviating oxidative stress， etc. Finally， we discussed the relative advantages and disadvantages of different encapsulation methods， as well as future trends for further development of probiotic delivery systems with health benefits.
