ObjectiveTo study the mechanism of Huanglian Jiedutang (HLJDT) in treating mice with atherosclerosis (AS) by improving ferroptosis. MethodsA total of 10 SPF C57BL/6J mice were selected as a normal group, and 50 ApoE-/- mice were randomly divided into five groups: model group, low-dose group of HLJDT, medium-dose group of HLJDT, high-dose group of HLJDT, and atorvastatin (ATV) group. ApoE-/- mice were fed a high-fat diet for eight weeks to establish the AS model, and at the 9th week, they were given normal saline, low, medium, and high doses of HLJDT (3.9, 7.8, 15.6 g·kg-1·d-1), and atorvastatin calcium tablets (0.01 g·kg-1·d-1), respectively, for a total of eight weeks. The formation of aortic plaque in mice was observed by gross oil red O staining and Masson staining. The levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C) in blood fat were measured by the automatic biochemical analyzer, and the mitochondrial structure of the aorta was observed by transmission electron microscopy. The content of serum superoxide dismutase (SOD) in serum was detected by enzyme-linked immunosorbent assay (ELISA). The content of reduced glutathione (GSH) in serum was detected by the microplate method, and that of malondialdehyde (MDA) in serum was detected by the TBA method. The protein expression of nuclear factor E2-associated factor 2 (Nrf2)/glutathione peroxidase 4 (GPX4) signaling pathway was detected by Western blot. ResultsCompared with those of the normal group, the contents of TC, LDL-C, TG, HDL-C, and MDA in the serum and the aortic vascular plaque deposition of the model group were significantly increased (P<0.01), while the expression levels of SOD and GSH in serum, as well as Nrf2, solute carrier family 7 member 11 (SLC7A11), and GPX4 in aorta were significantly decreased (P<0.01). Mice in the model group appeared mitochondrial fragmentation and vacuolation in the aorta, volume atrophy, mitochondrial crista reduction, or a loose and disorganized form. Compared with those in the model group, the aortic vascular plaque deposition was significantly decreased in the low-dose, medium-dose, and high-dose groups of HLJDT and ATV group, and the contents of serum TC, LDL-C, TG, and MDA in serum were significantly decreased (P<0.05, P<0.01). The contents of serum SOD and GSH and the expression levels of Nrf2, SLC7A11, and GPX4 in the aorta were increased (P<0.05, P<0.01), and the symptoms of aortic mitochondrial vacuolation were alleviated. The number of cristae was increased, and they were ordered neatly. ConclusionHLJDT can reduce aortic vascular plaque deposition, decrease blood lipid and MDA expression, increase SOD and GSH expression, and ameliorate the pathological changes of ferroptosis, the mechanism of which is related to the Nrf2/GPX4 signaling pathway.

Diabetes mellitus (DM) is a metabolic disease caused by absolute or relative insulin deficiency and reduced insulin sensitivity in peripheral cells, posing a serious threat to global health. Chronic complications arising in the later stages of DM can lead to the decline or even loss of function in multiple organs, including the eyes, heart, liver, kidneys, nerves, and feet, making them the primary cause of mortality in DM patients. Although modern medicine has made some progress in the treatment of these complications, challenges such as high costs and adverse drug reactions remain. Thus, identifying highly effective drugs with minimal adverse effects has become a top priority. Astragalus membranaceus is a shining gem in the treasure trove of Chinese medicine. Numerous studies have shown that its primary active component, astragaloside Ⅳ, possesses various biological activities, including anti-inflammatory, antioxidant, and antiviral effects, as well as benefits for cardiac and cerebral function, nerve conduction, and myocardial protection. Meanwhile, the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway plays a crucial role in regulating oxidative stress, inflammatory responses, apoptosis, and autophagy. Extensive research has highlighted the significant role of this pathway in various DM complications, leading to widespread studies on its interaction with astragaloside Ⅳ. This review summarizes research findings on how astragaloside Ⅳ alleviates pancreatic cytotoxicity in DM patients by modulating the PI3K/Akt pathway. Additionally, it highlights its protective effects on basic cardiac function, inhibition of retinal cell damage, improvement of cerebral nerve dysfunction, reduction of chronic kidney and liver damage, and mitigation of neurovascular toxicity in the lower limbs. These insights provide a valuable reference for the clinical application of A. membranaceus and its active monomer, astragaloside Ⅳ, in the treatment of DM and its complications.

To develop a novel polyamino acid-based nanohydrogel drug delivery system for dexamethasone to enhance its delivery efficiency to the inner ear. A fluorescein-labeled polyglutamic acid-based polyamino acid dexamethasone nanohydrogel was synthesized, and its gelation time was measured. The hydrogel was surgically injected into the round window niche of guinea pigs to determine its degradation time in the middle ear cavity in vivo. The safety, pharmacokinetics, and distribution patterns of dexamethasone in the inner ear were evaluated. The hydrogel exhibited a gelation time of 80 seconds in a 37℃ water bath. In vivo, the hydrogel was almost completely degraded within 7 days in the middle ear cavity of guinea pigs. Transient hearing loss was observed one day after administration, but hearing gradually returned to normal over time. No significant cytotoxicity, vestibular stimulation signs, or pathological abnormalities in spiral ganglion cells were observed. Histopathological examination revealed no significant inflammatory reactions. Pharmacokinetic analysis demonstrated sustained drug release and prolonged dexamethasone activity. Immunofluorescence staining confirmed the distribution of dexamethasone in both the cochlea and vestibular organs. The polyamino acid nanohydrogel exhibits excellent injectability and biodegradability, representing a safe and effective drug delivery system for the inner ear.

Human naïve pluripotent stem cells (PSCs) hold great promise for embryonic development studies. Existing induction and culture strategies for these cells, heavily dependent on MEK inhibitors, lead to widespread DNA hypomethylation, aberrant imprinting loss, and genomic instability during extended culture. Here, employing high-content analysis alongside a bifluorescence reporter system indicative of human naïve pluripotency, we screened over 1,600 chemicals and identified seven promising candidates. From these, we developed four optimized media-LAY, LADY, LUDY, and LKPY-that effectively induce and sustain PSCs in the naïve state. Notably, cells reset or cultured in these media, especially in the LAY system, demonstrate improved genome-wide DNA methylation status closely resembling that of pre-implantation counterparts, with partially restored imprinting and significantly enhanced genomic stability. Overall, our study contributes advancements to naïve pluripotency induction and long-term maintenance, providing insights for further applications of naïve PSCs.

Objective To investigate the association between the variability of remnant cholesterol inflammatory index(RCII),a novel composite biomarker,and the risk of stroke,in order to provide a theoretical basis for stroke prevention.Methods A prospective cohort study was conducted on 38 659 Kailuan individuals who took annual physical examinations in 2006,2008,and 2010.These subjects were grouped based on the quartiles of RCII variability,which was represented by standard deviation(SD)and average real variability(ARV),and were followed up every 2 years,with the occurrence of stroke(including ischemic and hemorrhagic strokes),death,or the end of follow-up on December 31,2022 as the endpoints.Kaplan-Meier method was used to calculate the cumulative incidence rate of endpoint events across different groups,and log-rank test was used to compare the difference of cumulative incidence of endpoint events in each group.Multivariate Cox proportional hazards regression model was adopted to analyze the association between RCII variability and risk of stroke.Results Among the 38 659 participants,a total of 2 539 strokes occurred during a mean follow-up period of 11.22±2.26 years.After adjusting confounding factors,when the participants were grouped by the quartiles of RCII-SD,the hazard ratio(HR)for stroke was 1.034(95%CI:0.917~1.167,P=0.584),1.146(95%CI:1.018~1.290,P=0.025),and 1.209(95%CI:1.066~1.370,P=0.003),respectively in the Q2,Q3,and Q4 groups,when compared with the Q1 group(Ptrend<0.05).When they were grouped by the quartiles of RCII-ARV,the HR for stroke was 1.008(95%CI:0.894~1.136,P=0.901),1.109(95%CI:0.986~1.248,P=0.085),and 1.152(95%CI:1.018~1.303,P=0.025),respectively,in the Q2,Q3,and Q4 groups,when compared with the Q1 group.Furthermore,both sensitivity and stratified analyses yielded similar results.Conclusion RCII variability is significantly associated with stroke,and the risk of stroke is gradually increasing with increment of the variability.Countermeasures Relevant authorities can focus on reducing RCII variability as a central objective by establishing regular monitoring mechanism,strengthening lifestyle interventions,and standardizing dietary,exercise,and weight management in order to suppress the index fluctuations.The principle of stable lipid-lowering in medication and optimization of therapeutic regimens with stable efficacy should be emphasized to prevent the risk of additional vascular damage.

Objective:To investigate the effect of the number of positive preoperative serological tumor markers on the surgical approach and prognosis of patients with intrahepatic cholangiocarcinoma.Methods:This is a retrospective case-series study. Data from 548 patients with intrahepatic cholangiocarcinoma after radical resection from October 2010 to April 2019 were retrospectively collected in 10 hospitals of China. There were 277 males and 271 females with an age of (57.8±10.2)years(range:23 to 84 years). Four hundred and twenty-six patients(77.7%) had at least one positive preoperative serum tumor marker. The data collection included the results of 4 preoperative serological tumor markers,other preoperative indicators(5 prodromal symptoms, 6 medical history,8 preoperative serological indicators,5 preoperative imaging indicators,and 14 preoperative pathological examination indicators),baseline data (gender and age),surgical methods,and prognostic follow-up data. Four preoperative results of serologic tumor marker and surgical procedure were converted into categorical variables. The number of positive preoperative serum tumor markers was used as the treatment variable,the surgical method was used as the mediating variable,and the survival time was used as the outcome variable. Univariate and multivariate analysis were used to screen for other preoperative indicators which were independent factors that influenced the surgical procedure and the prognosis of patients as covariates to analyze the mediating effect.Results:Of the 548 patients included in the study, 176 patients (32.1%) underwent partial hepatectomy,151 patients(27.5%) underwent hemihepatectomy, and 221 patients(40.3%) underwent partial hepatectomy or hemihepatectomy combined with other treatments. The results of the univariate and multivariate analysis showed that the number of positive serum tumor markers,intrahepatic bile duct dilatation,portal vein invasion,pathological differentiation,pathological type,vascular invasion,T stage,N stage and maximum tumor diameter were independent factors influencing the surgical procedure(all P<0.05). Intrahepatic bile duct dilatation,pathological differentiation and T stage were independent prognostic factors for patients with intrahepatic cholangiocarcinoma(all P<0.05). Intrahepatic bile duct dilatation,differentiation and T stage were included as covariates in the mediation effect model. The results showed that the number of positive serum tumor markers before surgery had a negative predictive effect on the survival time of patients with intrahepatic cholangiocarcinoma ( β=-0.092, P=0.039),and had a positive predictive effect on the surgical method ( β=0.244, P<0.01). The number of positive serum tumor markers had a negative predictive effect on the survival time of patients with intrahepatic cholangiocarcinoma ( β=-0.151, P=0.002). Direct and indirect effects accounted for 71.3% and 28.7% of total effects,respectively. Conclusions:The higher the positive number of preoperative tumor markers,the worse the prognosis of patients with intrahepatic cholangiocarcinoma. The number of positive cells not only directly affects the prognosis of patients,but also indirectly affects the prognosis of patients by affecting the surgical method.

Objective:
To investigate the differences in enolase and laminin levels in vaginal epithelial tissues between mice successfully infected withGardnerellaand mice not infected with Gardnerella, providing information for further exploration of the correlation between enolase and laminin levels and the incidence of bacterial vaginosis.
Methods:
Gardnerella strains isolated, purified, and identified from vaginal secretions of patients with bacterial vaginosis were used to infect the vagina of mice and establish a mouse model of bacterial vaginosis. Successful and failed mice was defined as successful and failed groups, respectively. Differential expression of enolase and laminin in the vaginal epithelial tissue of two groups of mice was detected by Western blot. Modeling success rate was statistically analyzed, and the expression differences of enolase and laminin was compared between two groups.
Results:
One strain of Gardnerella vaginalis infected 10 SPF grade KM mice, 7 mice met the diagnostic criteria for bacterial vaginosis, and 3 mice failed to model, with a success rate of 70%. Western blot was used to detect protein expression levels, and the levels of laminin and enolase in the successfully modeled mouse vaginal epithelial tissue were significantly higher than those in the failed modeling group, with statistical differences between the two groups(P<0.05).
Conclusion
Enolase and laminin may be involved in the occurrence of bacterial vaginosis, however, further research is needed to determine the mechanisms through which they trigger the occurrence and development of the disease.
