In situ tumor vaccine has become an important strategy in cancer immunotherapy owing to its ability to induce immune responses locally and overcome tumor heterogeneity. However, the abnormal structure and mechanical properties of the tumor’s physical microenvironment significantly limit the efficiency of vaccine delivery and immune efficacy. In this review, the key factors in the tumor’s physical microenvironment, including solid pressure, interstitial fluid pressure, matrix stiffness, and tissue microstructure, are systematically discussed. Their obstructive roles in immune cell infiltration, antigen presentation, and immune activation are analyzed. The potential of approaches, such as radiotherapy, anti-angiogenic therapy, extracellular matrix degradation agents, nanomaterials, and hydrogel delivery platforms, in reshaping the tumor’s physical microenvironment is explored. This review aims to offer theoretical and practical guidance for optimizing in situ vaccine strategies through the regulation of the tumor’s physical microenvironment, ultimately advancing the precision and effectiveness of cancer immunotherapy.

In recent years,enhanced recovery after surgery(ERAS)has been widely used in clinical practice,aiming to optimize perioperative management measures through evidence-based medicine and reduce the physical and mental trauma,stress reactions,and complications of surgical patients through multidisciplinary collaboration.This paper examined the clinical practice of ERAS from the perspective of medical humanities,reviewed its development and characteristics,and first pointed out that the concept of"minimal harm"laid the medical humanities foundation for ERAS.However,the concept of"minimum harm"faced ethical and realistic challenges in practice,such as differentiated cognition between benefits and non-harm,the tension between generalization and personalization,and the gap between rehabilitation continuity and family care.This paper led into the caregiving perspective of social sciences,proposed"optimal care"as a supplement to the medical humanities concept of ERAS,and introduced its connotation and practice.The combination of"minimal harm"and"optimal care"can provide theoretical guidance for medical humanistic care in ERAS and innovate the practical path of medical humanities into clinical practice.

In recent years， enhanced recovery after surgery （ERAS） has been widely used in clinical practice， aiming to optimize perioperative management measures through evidence-based medicine and reduce the physical and mental trauma， stress reactions， and complications of surgical patients through multidisciplinary collaboration. This paper examined the clinical practice of ERAS from the perspective of medical humanities， reviewed its development and characteristics， and first pointed out that the concept of “minimal harm” laid the medical humanities foundation for ERAS. However， the concept of “minimum harm” faced ethical and realistic challenges in practice， such as differentiated cognition between benefits and non-harm， the tension between generalization and personalization， and the gap between rehabilitation continuity and family care. This paper led into the caregiving perspective of social sciences， proposed “optimal care” as a supplement to the medical humanities concept of ERAS， and introduced its connotation and practice. The combination of “minimal harm” and “optimal care” can provide theoretical guidance for medical humanistic care in ERAS and innovate the practical path of medical humanities into clinical practice.

Objective To investigate the prevalence of Cryptosporidium infection and the distribution of parasite species and genotypes among HIV-positive individuals in Jiangxi Province. Methods HIV-positive individuals' sociodemographic and clinical data were collected from three AIDS designated hospitals in Jiangxi Province from January 2022 to March 2023. Subjects' stool samples were collected, and genomic DNA was extracted from stool samples. Nested PCR assay was performed based on the small subunit ribosomal RNA (SSU rRNA) gene of Cryptosporidium, and Cryptosporidium gp60 gene was amplified in stool samples positive for the SSU rRNA gene. The second-round PCR amplification product was checked with 1.5% agarose gel electrophoresis, and the products of suspected positive amplifications were sequenced, followed by sequence alignment. The phylogenetic tree was created using the Neighbor-Joining method with the software MEGA 11.0, to characterize the species, genotypes and sub-genotypes of Cryptosporidium. Results A total of 382 HIV-positive individuals were enrolled, with two cases identified with Cryptosporidium infection (0.52% prevalence), and both cases had no abdominal pain or diarrhea. Following sequencing and sequence alignment, the gene sequences of these two Cryptosporidium isolates shared 99.76% and 99.88% similarity with the gene sequence of C. meleagridis isolates. Phylogenetic analysis based on the Cryptosporidium SSU rRNA gene sequence identified the species of these two Cryptosporidium-positive stool samples as C. meleagridis. Following nested PCR amplification of the Cryptosporidium gp60 gene, sequencing and sequence alignment, the two C. meleagridis isolates were characterized as III eA17G2R1 and III bA25G1R1a sub-genotypes, and the sub-genotype III bA25G1R1a was firstly described in humans. Conclusion The prevalence of Cryptosporidium is low among HIV-positive individuals in Jiangxi Province. The likelihood of Cryptosporidium infection cannot be neglected among HIV-positive individuals without diarrhea.
