BACKGROUND: Antenatal depression (AD) is one of the most common pregnancy complications. Recent studies indicated that immune responses during pregnancy may contribute to development of AD.
OBJECTIVE: This study aimed to identify possible inflammatory biomarkers in early pregnancy to predict maternal depressive symptoms before delivery.
METHODS: This case-control study was conducted within the Maternal and Infant Health (MI-Health) birth cohort (Beijing, China) and depressive symptoms were assessed by Zung Self-rating Depression Scale (SDS) in both second and third trimesters. By using immune multi-factors kits, we tested 26 inflammatory factors in the serum of 38 cases with antenatal depression symptoms in both trimesters (SDS ≥ 53) and 38 controls. Logistic regression was used to identify candidate biomarkers, and the predictive capabilities were evaluated by using Receiver Operator Characteristics (ROC) analysis.
RESULTS: The concentrations of ln(CCL24) (p = 0.020), IL-7 (p = 0.006) and IL-10 (p = 0.014) were higher in early pregnancy among women with depressive symptoms comparing to healthy controls. The difference remained statistically significant after adjusting for maternal age, education level, gestational diabetes mellitus, pre-pregnancy BMI and gestational weeks of blood sampling (OR(ln(CCL24)) = 4.625, OR(IL-7) = 1.414, OR(IL-10) = 1.151). In ROC analysis, ln(CCL24), IL-7, and IL-10 achieved discrimination for depressive symptoms antepartum, with the values of AUC estimated at 0.75.
CONCLUSIONS: The sample size is limited, and the infectious disease infection records were not collected for control.
CONCLUSIONS: Higher levels of CCL24, IL-7 and IL-10 may indicate the higher risk of antenatal depression and are potential biomarkers indicating pathogenesis of antenatal depression.

OBJECTIVE: Chronic graft-versus-host disease (cGVHD) is a significant complication following allogenic hematopoietic stem cell transplantation, often necessitating therapeutic interventions such as rituximab (RTX) and cyclosporin A (CsA). This study aims to elucidate the mechanisms by which RTX and CsA jointly address B-cell dysregulation in cGVHD, providing a theoretical foundation and scientific rationale for the treatment and prognostic evaluation of this condition.
METHODS: A total of 30 cGVHD mouse models were established by subjecting recipient mice to total body irradiation followed by injection of a mixed suspension of bone marrow cells and splenocytes from donor mice. From Day 2 to Day 29 post-model establishment, the mice received subcutaneous administration of RTX and CsA. Throughout the study, body weight, clinical cGVHD scores, and survival rates were monitored. Blood samples were collected via the orbital venous plexus. Serum levels of B-cell activating factor (BAFF) and pro-inflammatory factors were measured using enzyme-linked immunosorbent assay (ELISA), and the ratio of regulatory B cells (Bregs) in the blood sample was assessed via flow cytometry.
RESULTS: Mice with cGVHD exhibited a 14.5% decrease in body weight, elevated clinical scores, and more severe symptoms compared to the control group. Notably, all mice in both the cGVHD and control groups survived until the conclusion of the study. Induction of cGVHD resulted in B-cell dysregulation, evidenced by elevated serum BAFF levels and a decreased proportion of Bregs. However, treatment with RTX combined with CsA ameliorated B-cell dysregulation and significantly reduced serum levels of pro-inflammatory factors in cGVHD mice, with decreases of 39.78% in TNF-α and 37.89% in IL-6.
CONCLUSIONS: The combination of RTX and CsA effectively mitigates B-cell dysregulation in cGVHD, thereby reducing the severity and progression of the disease.

UNASSIGNED: The prevalence of asymptomatic fever among children is high and may be confused with fever caused by corona. The purpose of this study is to investigate the characteristics of inflammatory factors and cardiac enzymes in children with Covid-19 hospitalized with the initial manifestation of fever without other symptoms.
UNASSIGNED: In this descriptive-analytical cross-sectional study, all 200 children with positive Covid-19 were hospitalized in Hazrat Ali-Asghar Hospital in Tehran between 2018 and 2019. For gathering data, clinical records and demographic information of patients were noted in the made-researcher\'s checklist and the collected data were analyzed using SPSS software version 24.
UNASSIGNED: It was found that the relationship between the degrees of fever of the patients with the number of platelets was also inverse and significant. In addition, there was a significant relationship between the degree of fever of the patients and the LDH number, ALT number and segment and lymphocyte percentage of the patients. In addition, it was found that the passing time of fever has a significant relationship with ALT and ESR in such a way that with the passage of time, there is a higher probability of seeing an increase in ESR, but in the case of ALT, it increases in a shorter period of time and decreases more after the passage of time.
UNASSIGNED: According to the results of the present study, in case of suspected to Covid and fever in patients, along with other tests, AST, ALT, D-dimer, and CKMB can be used to diagnose Covid, in such a way that in Covid, AST is probably normal and mentioned other tests can be higher than normal.

UNASSIGNED: This study aimed to observe the intervention of Weizhuan\'an prescription on rats with precancerous lesions of gastric cancer (PLGC) as well as its regulation on gastric mucosal microflora and inflammatory factors and explore the pharmacodynamic mechanisms of Weizhuan\'an Formula.
UNASSIGNED: The rats were classified into the blank control group (BCG); low-, medium-, and high-dose groups of Weizhuan\'an prescription (LDG, MDG, and HDG, respectively); and natural recovery group (NRG) at random. The rats in the traditional Chinese medicine (TCM) group were given corresponding doses of Weizhuan\'an formula, while the rats in the NRG and BCG were given an equivalent volume of distilled water for 12 weeks. After that, gastric mucosa samples of rats were collected to observe the general and pathological changes in the gastric mucosa; the changes in gastric mucosal microflora were detected by 16S rDNA amplicon sequencing, and the inflammatory factors were analyzed by cytokine antibody microarray and Western blotting.
UNASSIGNED: The results suggest that compared with the BCG, the pathology of gastric mucosa and gastric mucosal microflora and inflammatory factors in rats with PLGC have changed significantly, while Weizhuan\'an formula effectively improved them, especially in the MDG and HDG (p < 0.05). Compared with the NRG, the abundance of probiotics such as Lactobacillus and Veillonella were increased, while the abundance of pathogens such as Proteobacteria and Pseudomonas was decreased (p < 0.05, p < 0.01), and the relative contents of IL-2, IL-4, IL-13, and MCP-1 in gastric mucosa were decreased (p < 0.05). Moreover, it can upregulate the DNA-binding transcriptional regulator, ABC type multidrug transport system, and related enzymes and affect the signaling pathways such as viral protein interaction with cytokine and cytokine receptor and T cell receptor signaling pathway significantly (p < 0.05, p < 0.01), which can promote drug absorption and utilization and repair damaged gastric mucosa.
UNASSIGNED: The study confirmed that Weizhuan\'an prescription can treat rats with PLGC by regulating gastric mucosal microflora and inflammatory factors.

BACKGROUND: Intussusception occurs in children and progresses rapidly. If not treated in time, it may lead to secondary complications such as intestinal perforation, which affect the quality of life and health of children. Surgery is the most common clinical treatment and has a good effect. However, the postoperative prognosis of children with intussusception has a correlation with the postoperative rehabilitation method. Therefore, in this study, we explored the relationship between postoperative rehabilitation, gastrointestinal function, and the expression of inflammatory factors in children with intussusception.
OBJECTIVE: To explore the relationship between postoperative rehabilitation, gastrointestinal function, and inflammatory factor levels in children with intussusception.
METHODS: The medical records of 18 children who were admitted to our hospital for intussusception surgery between October 2022 and May 2024 were retrospectively reviewed. The patients were divided into the routine nursing group (n = 6) and rehabilitation training group (n = 12) according to the postoperative rehabilitation method. The general data, gastrointestinal function, and inflammatory factor levels of the two groups were statistically analyzed. Pearson correlation analysis of gastrointestinal function, inflammatory factors, and postoperative rehabilitation was performed.
RESULTS: We found no significant intergroup differences in sex, age, or disease course (P > 0.05). The times to first defecation, bowel sound recovery, and anal exhaust were shorter and inflammatory factor levels were lower in the rehabilitation training group than in the routine nursing group (P < 0.05). Pearson correlation analysis showed that gastrin and motilin levels were positively correlated with postoperative rehabilitation (P < 0.05). Interleukin (IL)-2, IL-4, IL-6, IL-10, high-sensitivity C-reactive protein, and tumor necrosis factor-α levels were negatively correlated with postoperative rehabilitation (P < 0.05). Gastrointestinal function was positively correlated (P < 0.05), and levels of inflammatory factors were negatively correlated with postoperative recovery time (P < 0.05).
CONCLUSIONS: We found a positive correlation between gastrointestinal function and postoperative rehabilitation training, and a negative correlation between inflammatory factor levels and rehabilitation training in children with intussusception.

OBJECTIVE: This study aimed to investigate the potential causal association between Sleep Apnea Syndrome (SAS) and Depression, focusing on the roles of gut microbiota, serum metabolites, and inflammatory factors in these conditions.
METHODS: Mendelian Randomization (MR) analysis was performed using data from genome-wide association studies to assess 211 types of gut microbiota, 1400 serum metabolites, and 91 inflammatory factors as potential contributing factors. Causal inference was conducted using the Inverse Variance Weighted (IVW) method, with additional robustness checks through Cochran\'s Q test, MR-Egger regression intercept test, MR-PRESSO global test, and leave-one-out analysis.
RESULTS: The MR analysis indicated a positive correlation between the risk of SAS and Depression (OR = 1.12, 95 % CI: 1.05-1.19, P < 0.001), with a reciprocal analysis showing a similar positive correlation between Depression and the risk of SAS (OR = 1.19, 95 % CI: 1.07-1.31, P = 0.001). Additionally, causal associations were identified between 15 types of gut microbiota, 36 serum metabolites, and 2 inflammatory factors with SAS, and between 11 types of gut microbiota, 23 serum metabolites, and 3 inflammatory factors with Depression (IVW, all P < 0.05). The robustness of these findings was confirmed through the MR-Egger regression intercept test and MR-PRESSO global test.
CONCLUSIONS: This study provides epidemiological evidence of a bidirectional causal association between SAS and Depression, emphasizing the potential roles of gut microbiota, serum metabolites, and inflammatory factors in the pathogenesis of these disorders. These findings may inform the development of new therapeutic strategies.

Coccidiosis poses a significant challenge to the poultry industry. However, the excessive and improper use of anticoccidial drugs and vaccines has led to resistance and food safety concerns. Consequently, traditional Chinese herbs have garnered attention as a potentially safer and more effective alternative. ChangQing compound derived from various Chinese herbal medicines is a promising anticoccidiosis agent, but its therapeutic effects have not been comprehensively evaluated. This study aimed to assess the therapeutic efficacy of ChangQing Compound against Eimeria tenella-induced coccidiosis in chickens on the basis of physiological indicators, cecum lesions, and changes in microbial diversity. The comparison with the positive control group revealed the average weight gain (AWG) and anticoccidial index (ACI) of the chicks were significantly higher, in contrast, the feed conversion ratio (FCR), cecal lesion score (CLS), and oocyst count per gram of cecal content (OPG) were significantly lower (P<0.05). Notably, AWG (138.87 g), OPG (0.57 × 106), ACI (177.92), and FCR (2.51) reflected the significant therapeutic effect of the 2.5 g/L ChangQing compound treatment (CQM). Histological sections showed that the cecal villus damage and intestinal wall swelling were minimal in the CQM, consistent with the CLS (0.73). Additionally, the 2.5 g/L ChangQing compound treatment effectively prevented the decrease of red blood cells, platelets, and hemoglobin, while promoting the release of anti-inflammatory factors interleukin-10 and interleukin-4, and inhibiting the pro-inflammatory factors interferon-γ and interleukin-17. The microbial community structure in the CQM was most similar to that of the negative control group. In summary, ChangQing compound had multiple positive effects (e.g., promoting weight gain, alleviating anemia, suppressing coccidial proliferation, reducing intestinal damage, modulating immunity, and maintaining intestinal microbiota homeostasis). The study results may be relevant to developing a novel strategy for the clinical management of coccidiosis.

Objectives: This study aimed to explore the relationship between circulating metabolites and postmenopausal osteoporosis (PMOP) and to assess the mediating role of inflammatory factors. Methods: Utilizing summary-level data from genome-wide association studies (GWAS) and employing a Mendelian Randomization approach, a two-sample MR analysis was conducted to assess the relationship between circulating metabolites and PMOP. Additionally, a two-step MR was used to quantify the mediating impact of inflammatory factors on the effect of circulating metabolites on PMOP. Results: The results revealed a significant association between certain metabolites and the risk of PMOP, notably the ratio of free cholesterol to total lipids in very large VLDL particles (OR: 1.399, 95% CI: 1.002-1.954, p = 0.048) and IL-16 (OR: 0.773, 95% CI: 0.608-0.983, p = 0.036). IL-16 was found to partially mediate the impact of circulating metabolites on PMOP, with a mediation effect of 10.4%. Conclusion: This study underscores the crucial role of circulating metabolites and inflammatory factors in PMOP pathogenesis. A causal relationship between circulating metabolites and PMOP was established, with IL-16 mediating some effects. These findings hold promise for clinical applications in early detection, personalized medicine, and the identification of therapeutic targets for PMOP.

Sepsis, a life-threatening condition, involves complex interactions among metabolic alterations, inflammatory mediators, and host responses. This study utilized a bidirectional Mendelian randomization approach to investigate the causal relationships between 1400 metabolites and sepsis, and the mediating role of inflammatory factors. We identified 36 metabolites significantly associated with sepsis (p < 0.05), with AXIN1, FGF-19, FGF-23, IL-4, and OSM showing an inverse association, suggesting a protective role, while IL-2 exhibited a positive correlation, indicating a potential risk factor. Among these metabolites, Piperine and 9-Hydroxystearate demonstrated particularly interesting protective effects against sepsis. Piperine\'s protective effect was mediated through its interaction with AXIN1, contributing to a 16.296% reduction in sepsis risk. This suggests a potential pathway where Piperine influences sepsis outcomes by modulating AXIN1 levels. 9-Hydroxystearate also exhibited a protective role against sepsis, mediated through its positive association with FGF-19 and negative association with IL-2, contributing 9.436% and 12.565%, respectively, to its protective effect. Experimental validation confirmed significantly elevated IL-2 levels and reduced FGF-19, AXIN1, piperine, and 9-hydroxyoctadecanoic acid levels in sepsis patients compared to healthy controls. Piperine levels positively correlated with AXIN1, while 9-hydroxyoctadecanoic acid levels negatively correlated with IL-2 and positively correlated with FGF-19, supporting the Mendelian randomization findings. Our findings provide insights into the molecular mechanisms of sepsis, highlighting the unique roles and contributions of specific metabolites and their interactions with inflammatory mediators. This study enhances our understanding of sepsis pathophysiology and opens avenues for targeted therapeutic interventions and biomarker development for sepsis management. However, further research is essential to validate these pathways across diverse populations and fully explore the roles of these metabolites in sepsis.

BACKGROUND: Whey protein (WP), a high-biological-value protein contained in milk, may have anti-inflammatory properties and can reduce proinflammatory cytokines; however, the current evidence is inconclusive.
OBJECTIVE: The aim of this study was to further investigate the effects of whey protein supplementation on inflammatory factors and oxidative stress in adults.
METHODS: We conducted a comprehensive search up to March 2022 using relevant key words in databases such as PubMed, Scopus, Embase, and the Cochrane Central Register of Controlled Trials, focusing on randomized controlled trials (RCTs).
METHODS: RCTs that examined the impact of WP on C-reactive protein, tumor necrosis factor alpha, interleukin-6, glutathione, malondialdehyde, and total antioxidant capacity were selected independently by 2 authors. Results were pooled using a random-effects model as weighted mean differences and 95% CIs.
METHODS: The results of the present study demonstrated that WP supplementation had no significant effect on the modulation of inflammation and oxidative stress compared with the control. None of the predefined subgroup analyses explained the differences in the effects of WP supplementation on inflammatory factors and oxidative stress.
CONCLUSIONS: This research suggests that WP supplementation had no significant effect on inflammatory factors and oxidative stress.
