Objective To explore the relationship between ambulatory blood pressure changes and health-related behaviors as well as sleep quality in hypertensive patients. Methods A retrospective study was conducted on 684 patients who underwent 24-hour ambulatory blood pressure monitoring at Chengdu Fifth People's Hospital between January 2023 and April 2025. The cohort included 502 hypertensive patients and 182 non-hypertensive patients. Clinical data from both groups of patients were collected. Their health-related behaviors and sleep quality were investigated. Pearson correlation analysis was conducted to explore the relationship between ambulatory blood pressure changes and health-related behaviors as well as sleep quality in hypertensive patients. Results The differences in dSBP, dDBP, nSBP, nDBP, 24-hour SBP, 24-hour DBP, 24-hour SBP CV, and 24-hour DBP CV levels between the two groups were statistically significant (P<0.05). The scores of the Active Health Behavior Scale (AHBS) in the hypertension group were lower than those in the non-hypertension group, while the scores of the Pittsburgh Sleep Quality Index (PSQI) in the hypertension group were higher than those in the non-hypertension group (P<0.05). AHBS showed a negative correlation with dSBP, dDBP, nSBP, nDBP, 24 h SBP, 24 h DBP, 24 h SBP CV, and 24 h DBP CV (P<0.05), while PSQI showed a positive correlation with dSBP, dDBP, nSBP, nDBP, 24 h SBP, 24 h DBP, 24 h SBP CV, and 24 h DBP CV (P<0.05). Conclusion Health-related behaviors and sleep quality can influence ambulatory blood pressure through various mechanisms, including neural, endocrine, and vascular functions.

Ulcerative colitis (UC) is a chronic and recurrent inflammatory bowel disease (IBD) that has become a major gastroenterologic problem during recent decades. Numerous complicating factors are involved in UC development such as oxidative stress, inflammation, and microbiota disorder. These factors exacerbate damage to the intestinal mucosal barrier. Spirulina platensis is a commercial alga with various biological activity that is widely used as a functional ingredient in food and beverage products. However, there have been few studies on the treatment of UC using S. platensis aqueous extracts (SP), and the underlying mechanism of action of SP against UC has not yet been elucidated. Herein, we aimed to investigate the modulatory effect of SP on microbiota disorders in UC mice and clarify the underlying mechanisms by which SP alleviates damage to the intestinal mucosal barrier. Dextran sulfate sodium (DSS) was used to establish a normal human colonic epithelial cell (NCM460) injury model and UC animal model. The mitochondrial membrane potential assay 3-‍‍(4,5-dimethylthiazol-2-yl)-2,‍5-diphenyltetrazolium bromide (MTT) and staining with Annexin V-fluorescein isothiocyanate (FITC)/propidium iodide (PI) and Hoechst 33258 were carried out to determine the effects of SP on the NCM460 cell injury model. Moreover, hematoxylin and eosin (H&E) staining, transmission electron microscopy (TEM), enzyme-linked immunosorbent assay (ELISA), quantitative real-time polymerase chain reaction (qPCR), western blot, and 16S ribosomal DNA (rDNA) sequencing were used to explore the effects and underlying mechanisms of action of SP on UC in C57BL/6 mice. In vitro studies showed that SP alleviated DSS-induced NCM460 cell injury. SP also significantly reduced the excessive generation of intracellular reactive oxygen species (ROS) and prevented mitochondrial membrane potential reduction after DSS challenge. In vivo studies indicated that SP administration could alleviate the severity of DSS-induced colonic mucosal damage compared with the control group. Inhibition of inflammation and oxidative stress was associated with increases in the activity of antioxidant enzymes and the expression of tight junction proteins (TJs) post-SP treatment. SP improved gut microbiota disorder mainly by increasing antioxidant enzyme activity and the expression of TJs in the colon. Our findings demonstrate that the protective effect of SP against UC is based on its inhibition of pro-inflammatory cytokine overproduction, inhibition of DSS-induced ROS production, and enhanced expression of antioxidant enzymes and TJs in the colonic mucosal barrier.

BACKGROUND: In many studies, rats were commonly used as models of retrorsine-induced hepatic injury. Some reports have confirmed that retrorsine cannot inhibit proliferation of mouse hepatic cells. Other reports have shown that retrorsine has inhibitory effects on proliferation of mouse hepatic cells. OBJECTIVE: To study the liver regeneration after hepatic injury by creating mouse models treated with partial hepatectomy combination with retrorsine. METHODS: A total of 40 C57BL/6J mice were equally and randomly assigned to 2 groups. In the partial hepatectomy combined with retrorsine group, intraperitoneal injection of retrorsine 70 mg/kg was conducted, twice, within an interval of 2 weeks. Four weeks later, 2/3 hepatectomy was performed. In the partial hepatectomy group, intraperitoneal injection of saline 70 mg/kg was performed, twice, with an interval of 2 weeks. Four weeks later, 2/3 hepatectomy was performed. At 14 days after partial hepatectomy, the restoration of the livers was observed. The liver cell injury was observed at 3, 7 days with hematoxylin-eosin staining. The hepatocyte proliferation was observed at 3 days with BrdU staining. Oval cell proliferation was observed at 3, 7and 14 days with CK19 and C-kit antibody immunohistochemistry.RESULTS AND CONCLUSION: In the partial hepatectomy group, the damaged liver nearly restored to normal at 14 days after partial hepatectomy, and the result was contrary to partial hepatectomy combined with retrorsine group. Hematoxylin-eosin staining demonstrated that significant degeneration changes in hepatic cells in the partial hepatectomy combined with retrorsine group. BrdU staining showed that hepatocyte proliferation at day 3 was significantly determined in the partial hepatectomy group, but few in the partial hepatectomy combined with retrorsine group. CK19 and C-kit immunohistochemistry demonstrated that visible oval cell proliferation was seen in mice of partial hepatectomy combined with retrorsine group. First of all, hepatic oval cells appeared in portal area and differentiated into hepatic cells and bile duct cells, and then grew into the hepatic lobule gradually. These indicated that retrorsine can obviously inhibit hepatocyte regeneration after liver injury in mice. The model of mice treated with retrorsine and partial hepatectomy could induce oval cell proliferation.
