ObjectiveTo investigate the mechanism of Si Junzitang in treating liver injury in rats with spleen Qi deficiency syndrome based on transcriptomics and to experimentally verify its effects. MethodsSixty male SD rats were randomly divided into blank group, model group, low-dose Si Junzitang (6 g·kg-1·d-1), medium-dose Si Junzitang group (12 g·kg-1·d-1), high-dose Si Junzitang group (24 g·kg-1·d-1), and natural recovery group, with 10 rats in each group. A composite multifactorial modeling method (forced swimming + intragastric administration of Xiao Chengqitang + irregular diet) was used to establish a spleen Qi deficiency model. After 30 days of continuous intervention, body weight and 3-hour food intake were measured, and macroscopic symptom scores for spleen Qi deficiency syndrome were evaluated. Serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in each group were detected, and hematoxylin and eosin (HE) staining was used to observe histopathological changes in liver tissue. Transcriptome sequencing (RNA-Seq) was used to identify differentially expressed genes (DEGs) among the blank, model, and high-dose Si Junzitang groups. Gene ontology(GO) and Kyoto encyclopedia of genes and genome(KEGG) enrichment analyses were performed on the DEGs. Immunofluorescence (IF) and Western blot were used to detect NOD-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein (ASC), Caspase-1, and the N-terminal domain of gasdermin D (GSDMD-N). Immunohistochemistry (IHC) was used to detect the expression of downstream inflammatory cytokines interleukin-1β (IL-1β), interleukin-6 (IL-6), and interleukin-18 (IL-18). ResultsCompared with the blank group, the model group showed significantly reduced body weight and 3-hour food intake, significantly increased macroscopic symptom scores, and elevated serum AST and ALT levels (P<0.01), with mild inflammatory liver injury observed histologically. Compared with the model group, Si Junzitang at all doses significantly improved these parameters and alleviated liver injury in a dose-dependent manner (P<0.05,P<0.01). RNA-Seq analysis revealed 1 254 DEGs between the blank and model groups, and 842 DEGs between the model and high-dose Si Junzitang groups. GO and KEGG enrichment analyses indicated that the NOD-like receptor signaling pathway was activated in liver injury associated with spleen Qi deficiency, suggesting that the NLRP3 inflammasome may be a key target. Results from IF, IHC, and Westernblot showed that compared with the blank group, the expression of NLRP3, ASC, Caspase-1, GSDMD-N, and the downstream inflammatory cytokines IL-1β, IL-6, and IL-18 were significantly increased in the model group (P<0.01), while these levels were markedly decreased in the high-dose Si Junzitang group (P<0.01). ConclusionSi Junzitang effectively improves mild inflammatory liver injury in rats with spleen Qi deficiency syndrome in a dose-dependent manner. Its mechanism may be associated with inhibition of the NLRP3/ASC/Caspase-1 signaling pathway, downregulation of the pyroptosis executioner protein GSDMD-N, and reduction of pyroptosis-related inflammatory cytokine release.

OBJECTIVE:
To evaluate the efficacy and safety of Shexiang Tongxin Dropping Pill (STDP) in treating stable angina patients with phlegm-heat and blood-stasis syndrome by exercise duration and metabolic equivalents.
METHODS:
This multicenter, randomized, double-blind, placebo-controlled clinical trial enrolled stable angina patients with phlegm-heat and blood-stasis syndrome from 22 hospitals. They were randomized 1:1 to STDP (35 mg/pill, 6 pills per day) or placebo for 56 days. The primary outcome was the exercise duration and metabolic equivalents (METs) assessed by the standard Bruce exercise treadmill test after 56 days of treatment. The secondary outcomes included the total angina symptom score, Chinese medicine (CM) symptom scores, Seattle Angina Questionnaire (SAQ) scores, changes in ST-T on electrocardiogram and adverse events (AEs).
RESULTS:
This trial enrolled 309 patients, including 155 and 154 in the STDP and placebo groups, respectively. STDP significantly prolonged exercise duration with an increase of 51.0 s, compared to a decrease of 12.0 s with placebo (change rate: -11.1% vs. 3.2%, P<0.01). The increase in METs was significantly greater in the STDP group than in the placebo group (change: -0.4 vs. 0.0, change rate: -5.0% vs. 0.0%, P<0.01). The improvement of total angina symptom scores (25.0% vs. 0.0%), CM symptom scores (38.7% vs. 11.8%), reduction of nitroglycerin consumption (100.0% vs. 11.3%), and all domains of SAQ, were significantly greater with STDP than placebo (all P<0.01). The changes in Q-T intervals at 28 and 56 days from baseline were similar between the two groups (both P>0.05). Twenty-five participants (16.3%) with STDP and 16 (10.5%) with placebo experienced AEs (P=0.131), with no serious AEs observed.
CONCLUSION
STDP could improve exercise tolerance in patients with stable angina and phlegm-heat and blood stasis syndrome, with a favorable safety profile. (Registration No. ChiCTR-IPR-15006020).

OBJECTIVE:
EPF3 is a fibrinolysin monomer isolated and purified from Pheretima vulgaris Chen, an earthworm used in traditional Chinese medicine as Dilong for treating blood stasis syndrome. Its composition, anticoagulant and fibrinolytic activities, and relevant mechanisms have been confirmed through in vitro experiments. However, whether it has antithrombotic effects in vivo and can be absorbed by the gastrointestinal tract is unknown. This study evaluates the antithrombotic effect in zebrafish and investigates the gastrointestinal stability and intestinal absorption mechanism of this protein in vitro.
METHODS:
The antithrombotic effect of EPF3 in vivo was verified using the zebrafish thrombus model induced by arachidonic acid and FeCl3. Then, the protein bands of EPF3 incubated with simulated gastric fluid (SGF), simulated intestinal fluid (SIF), and homogenate of Caco-2 cells (HC2C) were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis to evaluate its gastrointestinal stability. Finally, the transport behavior and absorption mechanism of EPF3 were studied using Caco-2 cell monolayer.
RESULTS:
EPF3 could significantly enhance the returned blood volume and blood flow velocity in zebrafish with platelet aggregation thrombus induced by arachidonic acid. It could also prolong the formation time of tail artery thrombus and increase the blood flow velocity in zebrafish with vessel injury thrombus induced by FeCl3. EPF3 was stable in SIF and HC2C and unstable in SGF. The permeability of EPF3 in Caco-2 monolayer was time-dependent and concentration-dependent. The efflux ratio was less than 1.2 during transport, and the transport behavior was not affected by inhibitors. EPF3 could reversibly reduce the expression of tight junction-related proteins, including zonula occludens-1, occludin, and claudin-1 in Caco-2 cells.
CONCLUSION
EPF3 could play a thrombolytic and antithrombotic role in zebrafish. It could be transported and absorbed into the intestine through cellular bypass pathway by opening the intestinal epithelium tight junction. This study provides a scientific explanation for the antithrombotic effect of earthworm and provides a basis for the feasibility of subsequent development of EPF3 as an antithrombotic enteric-soluble preparation.

OBJECTIVE:
This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study.
METHODS:
A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants.
RESULTS:
Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m 2) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m 2) and obesity (≥ 28.0 kg/m 2) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m 2 ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses.
CONCLUSION
This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective:To investigate the sense of coherence, job stressors and mental health status of nurses practitioners, and analyze the correlation among them.Methods:In September 2020, nurses practitioners in Chengdu City, Sichuan Province were selected as the research objects by convenience sampling method. The Sense of Coherence Scale, Nurses' Job Stressors Scale and SCL-90 were used to investigate their sense of coherence, job stressors and mental health status, respectively. Pearson correlation test was used to analyze the correlation among them, and the structural equation model was constructed to explore the mechanism of them.Results:A total of 1693 nurse practitioners were included. The total scores of sense of coherence, job stressors and SCL-90 were (65.00±14.01) points, (69.08±18.38) points and (129.68±52.99) points, respectively. The mean scores of all dimensions of sense of coherence of nurse practitioners were negatively correlated with the mean scores of all dimensions of job stressors and SCL-90 ( P<0.001). And there were positive correlations between the mean scores of all dimensions of job stressors and the mean scores of all dimensions of SCL-90 ( P<0.001). The structural equation model fitted well. The path coefficient between job stressors and sense of coherence was -0.372 ( P<0.001), and the path coefficient between sense of coherence and SCL-90 score was -0.647 ( P<0.001) . Conclusion:The sense of coherence plays a significant buffering role in job stressors and mental health of nurses practitioners. Nursing managers should be committed to improving the level of sense of coherence of nurses, enhance the happiness of nurses at work, and improve their mental health level.
