This paper systematically reviews the core concepts and lines of theoretical inheritance of major spleen-stomach theories in traditional Chinese medicine (TCM), including spleen deficiency theory, spleen-stomach damp-heat theory, and liver-spleen disharmony theory. It is found that these theories have all undergone a developmental trajectory characterized by classical foundation, refinement of therapeutic methods, systematization of pathogenesis, and modern innovation. The evolution of spleen-stomach theory has achieved a shift from a singular focus on tonifying the spleen to regulating dynamic middle-jiao (焦) balance, and from localized spleen-stomach regulation to the circular movement of qi involving all five zang organs. In terms of modern disease-syndrome integrative research, spleen deficiency syndrome is shown to be closely associated with impairment of the gastrointestinal mucosal barrier, metabolic disorders, and gene polymorphisms related to Helicobacter pylori-associated gastric diseases. Spleen-stomach damp-heat syndrome is closely linked to hyperactive energy metabolism, inflammatory cytokines, and abnormal expression of aquaporins. Liver-spleen disharmony syndrome is mainly associated with dysregulation of the brain-gut axis and microbiota-related metabolic disorders. It is proposed that future research on spleen-stomach diseases and syndromes should further elucidate their potential multidimensional differential biological characteristics, thereby promoting the modernization of the TCM discipline of spleen-stomach studies.

Organ transplantation is an effective alternative treatment for patients with end-stage organ failure. However, the shortage of donor organs has limited the widespread application of clinical transplantation. In recent years, breakthroughs in CRISPR-Cas9 gene editing technology have overcome the barrier of hyperacute rejection in xenotransplantation, offering a potential solution to the organ shortage crisis. Rejection remains a critical factor affecting graft survival. Antigen-presenting cells play a vital role in the initiation and progression of rejection and immune regulation in xenotransplantation. Therefore, in-depth investigation into the role of antigen-presenting cells in xenotransplantation is of great significance. This article summarizes the roles and therapeutic strategies of professional antigen-presenting cells, including macrophages, dendritic cells and B cells in xenotransplantation, aiming to provide insights for future research on immune regulation mechanisms in this field.

Heparin-binding protein (HBP) is a pro-inflammatory granule protein released by activated neutrophils, known for its role in modulating vascular permeability and its pathological significance in infectious diseases. In recent years, HBP has garnered attention due to its immune-activating effects in contexts such as sepsis, acute lung injury and organ transplantation. It has been proposed as a potential biomarker for early detection of infection and inflammation. While preliminary progress has been made in animal studies, clinical evidence remains limited. Therefore, this article focuses on the mechanism of action of HBP in transplantation-related complications, explores its potential pathways for predicting infection risk, mediating ischemia-reperfusion injury and rejection, and evaluates the feasibility of intervention strategies such as neutralizing antibodies, heparin derivatives and albumin. The pivotal role of HBP in regulating inflammatory responses post-transplant may offer a novel target for postoperative infection monitoring and personalized therapeutic interventions.

Objective:
To investigate the effect of integrin α5 on the expression of NOD-like receptor thermal protein domain associated protein 3 (NLRP3) in periodontal ligament fibroblasts (PDLFs) within an inflammatory microenvironment.
Methods:
This study was approved by the Ethics Committee of Laboratory animals. After rat PDLFs were treated with LPS (0.5, 5, and 50 µg/mL) for 24 h, the primary medium was discarded and replaced with serum-free culture medium. After 24 h, the supernatant was collected and mixed with DMEM medium containing 10% exosome-free serum at a volume ratio of 1:1 to obtain conditioned medium (CM). The groups were labeled as the 0.5-CM, 5-CM, and 50-CM groups. In addition, PDLFs cultured in DMEM medium containing 10% exosome-free serum were considered the 0-CM group. PDLFs were cultured with the above CM. In the inhibitor group, PDLFs were cultured in 0-CM containing different concentrations of integrin α5 inhibitor ATN-161 (0, 0.025, 0.25, 2.5, 25, and 250 μg/mL). The effect of CM and integrin α5 inhibitor ATN-161 on cell viability was assessed using the CCK-8 assay. According to the CCK-8 results, in further inhibitor intervention experiments, PDLFs were cultured in 0-CM, 5-CM (without/with 25 μg/mL ATN-161), and 0-CM containing 25 μg/mL ATN-161, which were labeled as the 0-CM, 5-CM, ATN-161+5-CM, and ATN-161 groups, respectively. The expression changes of integrin α5 and NLRP3 were detected using Western blot and qRT-PCR techniques. For in vivo experiments, 24 rats were randomly divided into four groups (n=6). The control group contained healthy rats that received no treatment. The rats in the other three groups were injected with 40 µL of 0-CM containing 25 μg/mL ATN-161 or 5-CM (without or with 25 μg/mL ATN-161) on the palatal side of the left maxillary first molar every three days; these groups were classified as the ATN-161, 5-CM, and ATN-161+5-CM groups, respectively. On the 30th day, the left maxillary tissue of rats was used for Micro-CT, HE staining, and immunohistochemical detection.
Results :
The CCK-8 assay showed that CM, 25 μg/mL ATN-161, and ATN-161 concentrations below 25 μg/mL had no significant effect on cell viability at 12 h and 24 h (P > 0.05). 50-CM and 25 μg/mL ATN-161 significantly inhibited cell viability at 48 h (P < 0.05). For in vitro experiments, compared to the 0-CM group, both the protein and mRNA levels of integrin α5 and NLRP3 were significantly increased in rat PDLFs in the 5-CM group (P < 0.05). Intervention with 25 μg/mL ATN-161 significantly attenuated the enhancement of 5-CM on the expression of integrin α5 and NLRP3 (P < 0.05). For in vivo experiments, compared to the control group, alveolar bone resorption and periodontal inflammatory cell infiltration were significantly increased in the 5-CM and ATN-161+5-CM groups, and the expression of integrin α5 and NLRP3 was significantly increased (P < 0.01). However, compared to the 5-CM group, the ATN-161+5-CM group had less alveolar bone resorption and fewer periodontal inflammatory cells. Further, the expression of integrin α5 and NLRP3 was significantly reduced (P < 0.01).
Conclusion
In vitro and in vivo experiments showed that integrin α5 mediated NLRP3 expression in PDLFs under an inflammatory microenvironment. ATN-161 inhibited the expression of integrin α5, thus significantly downregulating the expression of NLRP3, which plays a role in inhibiting inflammation.

OBJECTIVE To investigate the effects and potential mechanism of paeoniflorin on oxidative stress of ulcerative colitis (UC) mice based on adenosine monophosphate-activated protein kinase (AMPK)/nuclear factor-erythroid 2-related factor 2 (Nrf2) pathway. METHODS Male BALB/c mice were randomly divided into control group, model group, inhibitor group (AMPK inhibitor Compound C 20 mg/kg), paeoniflorin low-, medium- and high-dose groups (paeoniflorin 12.5, 25, 50 mg/kg), high- dose of paeoniflorin+inhibitor group (paeoniflorin 50 mg/kg+Compound C 20 mg/kg), with 8 mice in each group. Except for the control group, mice in all other groups were given 4% dextran sulfate sodium solution for 5 days to establish the UC model. Subsequently, mice in each drug group were given the corresponding drug solution intragastrically or intraperitoneally, once a day, for 7 consecutive days. The changes in body weight of mice were recorded during the experiment. Twenty-four hours after the last administration, colon length, malondialdehyde (MDA) content, and activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in colon tissues were measured; histopathological morphology of colon tissues, tight junctions between intestinal epithelial cells, and histopathological scoring were all observed and evaluated; the mRNA expressions of AMPK and Nrf2, as well as the protein expressions of heme oxygenase-1(HO-1), occludin and claudin-1, were all determined in colon tissue. RESULTS Compared with model group, paeoniflorin groups exhibited recovery from pathological changes such as inflammatory cell infiltration and crypt damage in the colon tissue, as well as improved tight junction damage between intestinal epithelial cells. Additionally, significant increases or upregulations were observed in body weight, colon length, activities of SOD and GSH-Px, phosphorylation level of AMPK, and protein expression of Nrf2, HO-1, occludin, claudin-1, and mRNA expressions of AMPK and Nrf2; concurrently, MDA content and histopathological scores were significantly reduced (P< 0.05 or P<0.01). In contrast, the inhibitor group showed comparable (P>0.05) or worse (P<0.05 or P<0.01) indicators compared to the model group. Conversely, the addition of AMPK inhibitor could significantly reverse the improvement of high- dose paconiflorin (P<0.01). CONCLUSIONS Paeoniflorin can repair intestinal epithelial cell damage in mice, improve tight junctions between epithelial cells, upregulate the expression of related proteins, and promote the expression and secretion of antioxidant-promoting molecules, thereby ameliorating UC; its mechanism may be associated with activating AMPK/Nrf2 antioxidant pathway.

ObjectiveBased on the theory of "gut-prostate" axis, this study explored the effects and mechanisms of Zishen Tongguan formula and Cinnamomi Cortex in the formula in treating rats with chronic non-bacterial prostatitis(CNP) by detecting the levels of inflammatory factors, and the composition and structure of intestinal flora in CNP rats. MethodsEight out of 42 SD rats were randomly selected as the normal group, and the remaining rats were injected with carrageenan to prepare the CNP model. After successful modeling, 32 rats were randomly divided into the model group, Ningmitai capsule group(0.50 g·kg-1), Zishen Tongguan formula group(2.00 g·kg-1), and the Phellodendri Chinensis Cortex-Anemarrhenae Rhizoma pair group(PCC-AR group, 2.00 g·kg-1), with 8 rats in each group. The administered groups were given the corresponding medicinal solution by gavage, and the normal and model groups were intragastrically administered with an equal volume of normal saline, once a day for 14 consecutive days. The prostate tissues of rats were collected and subjected to hematoxylin-eosin(HE) staining and Masson staining to observe the pathological changes of the tissues in each group. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of related inflammatory factors in rat serum, and 16S rDNA sequencing was used to analyze the abundance and diversity changes of gut microbiota before and after administration, and species difference analysis was performed. ResultsAll the administered groups could alleviate the inflammatory symptoms of CNP rats, increase the expression levels of anti-inflammatory factors and decrease the expression levels of pro-inflammatory factors, with the most sIgnificant effect observed in the Zishen Tongguan formula group. Compared with the normal group, the expression levels of interleukin(IL)-8, hypersensitive C-reactive protein(hs-CRP), immunoglobulin(Ig)M, secretory IgA (sIgA), and inducible nitric oxide synthase(iNOS) were sIgnificantly increased in the model group(P<0.01). Compared with the model group, the expression levels of the above inflammatory factors in all administered groups were significantly reduced(P<0.01). When compared with the PCC-AR group, the Zishen Tongguan formula group showed a significant decrease in transforming growth factor(TGF)-β1 expression level(P<0.05) and a significant increase in IgM expression level(P<0.01). The results of gut microbiota analysis showed that, compared with the PCC-AR group, at the order level, the Zishen Tongguan formula group significantly reduced the relative abundance of conditional pathogens such as Bacteroidales, Acidaminococcales, Rhodospirillales, Clostridiales, and Elusimicrobiales(P<0.01). And at the genus level, the Zishen Tongguan formula group significantly decreased the relative abundance of pathogenic microbiota such as Lachnospira and Bacteroides(P<0.01) and significantly increased the relative abundances of beneficial microbiota such as Ruminococcus and Lactobacillus(P<0.01). ConclusionZishen Tongguan formula can reduce the level of harmful intestinal bacteria, increase the level of beneficial intestinal bacteria, down-regulate the expression of serum inflammatory factors, and the small amount of Cinnamomi Cortex in the formula may play a key role in the treatment of CNP with this formula.

[Objective] To analyse the distribution of antigen phenotypes in the Rh, MNS and Kidd blood group systems of Han and Tujia blood donors in Chongqing, and to provide data support for the establishment of an expanded blood group antigen phenotype database and the development of expanded blood group coordinated transfusion in blood donors. [Methods] The antigens of Rh, MNS and Kidd blood group systems in Han and Tujia blood donors in Chongqing were detected by test-tube method, and the Hardy-Weinborg anastomosis of the three blood group systems was calculated. Pearson's chi-square test and Fisher's exact probability method were used to compare the differences in phenotypic distribution frequencies among different regions and ethnic groups. [Results] Han and Tujia blood donors accounted for the highest proportion of CCee in the antigenic phenotype of the Rh blood group system, followed by CcEe, and then Ccee and ccEE. Tujia blood donors accounted for 52.02% of CCee, which was higher than that of Han blood donors (47.24%), while Han blood donors accounted for 32.20% of CcEe, which was higher than that of Tujia blood donors (28.94%). In the antigenic phenotype of the MNS blood group system, the blood donors of Han nationality and Tujia were MN>MM>NN,. The antigen phenotype distribution frequency of the Kidd blood group system was highest for Jk(a+b+) among both Han and Tujia blood donors, and the blood donors of Han nationality were Jk(a+b+)>Jk(a+b+), while those of Tujia were Jk(a-b+)>Jk(a+b-). The antigens of the three blood groups of Han and Tujia blood donors were consistent with the Hardy-Weinberg balance(P>0.05). There was no statistically significant difference in the frequency of antigen phenotypes of the three blood group systems between Han and Tujia blood donors(P>0.05). There were statistically significant differences in the phenotypic distribution frequency of Rh antigens between Chongqing and Xi'an, Zhejiang, Shantou, Foshan, Nanning and Yangzhou(P<0.05), but not with Guang'an and Shenzhen(P>0.05). There were statistically significant differences in the phenotypic distribution frequency of Rh antigens between Han, Tujia, Zang, Mongolian, Korean and Hani ethnic groups in Chongqing(P<0.05). There were statistically significant differences in the phenotypic distribution frequency of MNS antigens between Han blood donors in Chongqing and Urumqi, Hainan and Yuncheng, but not with Xi'an and Wenzhou. There was a statistically significant difference in the phenotypic distribution frequency of MNS antigen between Tujia blood donors in Chongqing and Urumqi and Hainan(P<0.05), but there was no significant difference in the phenotypic distribution frequency of MNS antigen between Tujia blood donors in Chongqing, Urumqi and Hainan(P>0.05). There was a statistically significant difference in the phenotypic distribution frequency of Kidd antigens between blood donors in Chongqing and Harbin(P<0.05), but not in Huizhou, Wenzhou and Yichang(P>0.05). [Conclusion] The population in Chongqing has multi-ethnic characteristics, and the antigenic phenotypes of Rh, MNS and Kidd blood group systems exhibit diversity and regional differences. Establishing an expanded blood bank can provide more options for precision blood transfusion.
