Objective To investigate the impact of red blood cell suspension infusion across various perioperative periods on patients with valvular heart disease. Methods The patients with valvular heart disease admitted to Tianjin Chest Hospital from 2018 to 2020 were selected. Based on the timing of perioperative red cell suspension infusion, patients were categorized into three groups: a group 1 receiving intraoperative red cell suspension infusion, a group 2 receiving red cell suspension infusion within 24 hours after entering the ICU, and a group 3 receiving red cell suspension infusion at both time points. The laboratory results, perioperative blood component infusion volume, and other relevant parameters were retrospectively analyzed. After propensity score matching, the differences in different variables among the three groups were compared. Results After propensity score matching, 102 patients were enrolled, including 52 males and 50 females, with an average age of (61.74±10.58) years. There were 34 patients in each group. The preoperative hemoglobin (Hb) value of the group 2 was significantly higher than that of the group 1 and the group 3, and the amount of red cell suspension and autoblood transfusion was the lowest (P<0.05). Group 1 had the highest postoperative Hb, as well as the highest Hb and hematocrit (HCT) levels within 24 hours post-surgery (P<0.05). The group 1 had the lowest plasma, platelet and cryoprecipitate infusion volumes, and the shortest cardiopulmonary bypass time, aortic occlusion time, postoperative ICU stay and hospital stay, and the least blood loss and total drainage volume (P<0.05). The difference between postoperative and preoperative Hb (△Hb1) was highest in group 1 (P<0.05). Conclusion For patients with valvular heart disease, intraoperative-only infusion of red blood cell suspension is associated with a better prognosis at discharge and during follow-up.

Animal model research on spleen and stomach diseases in traditional Chinese medicine （TCM） is of great significance for elucidating the nature of diseases and syndromes and for revealing the mechanisms of action of Chinese herbal medicinals. At present， studies on classical TCM syndrome models of spleen and stomach diseases mainly focus on spleen deficiency syndrome， liver constraint syndrome， and damp-heat syndrome. Model construction is mostly based on the etiological and pathophysiological characteristics of syndrome， and model evaluation primarily involves macroscopic manifestations and physicochemical indicators. This paper summarizes the current research status of animal models integrating disease and syndrome for seven common spleen and stomach diseases， including chronic gastritis and gastric precancerous lesions， gastroesophageal reflux disease， functional dyspepsia， inflammatory bowel disease， irritable bowel syndrome， functional constipation， and functional diarrhea. The modeling methods and characteristics of disease-syndrome combined animal models for each disease are analyzed. It is proposed that future research on disease-syndrome integration in spleen and stomach diseases should move toward syste-matic， precise， and integrative development， and that interdisciplinary and cross-disciplinary research approaches should be adopted to enhance the predictive value and application efficiency of disease-syndrome combined animal models.

Objective: To assess the nutritional supply status of school meals for primary and secondary school students in Henan Province, so as to provide a basis for scientific guidance of school meals. Methods: During 2021-2023, 115 lunch and dinner samples were collected from 25 primary and secondary schools in Zhoukou, Anyang and Luoyang of Henan Province by a direct selection method, and 13 nutrients were determined for each sample. The nutrient supply was evaluated based on Nutrition Guidelines of School Meals and Reference Intake of Dietary Nutrients for Chinese Residents (2023 Edition). Mann-Whitney U test was used to compare the differences of nutritional supply between urban and rural schools. Results: The median values for energy (709.77 kcal,1 kcal=4.18 kJ), fat energy supply ratio (0.27) and carbohydrate energy supply ratio (0.55) in the 66 lunches and dinners from primary school were within the recommended range. The supply of protein (28.39 g) and sodium (1 464.59 mg) was excessive. The median values of zinc (2.62 mg) and dietary fiber (5.19 g) were lower than the reference values. No statistically significant differences were observed in the supply of 13 nutrients between urban and rural primary schools( U = 427.00 -633.00, P > 0.05 ). Among 49 samples from secondary schools, the median value of energy supply (930.02 kcal), carbohydrate energy ratio ( 0.54 ) and fat energy supply ratio(0.25) were within the recommended range; and the median values of protein (38.82 g) and sodium (2 556.80 mg) were higher than the standard; and the median values of calcium (250.32 mg) and vitamin B1 (0.16 mg) were lower than the standard. Additionally, the differences in the level of vitamin B2 ( U =372.00) and zinc ( U =375.00) between the urban and rural secondary schools were statistically significant ( P <0.05). Conclusion Nutrient supply of primary and secondary school meals in three cities of Henan Province is inadequate and imbalanced, and the recipe need to be further optimized and improved.

Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Aim To investigate the effects of lycopene on myocardial microvascular remodeling and elucidate its underlying mechanisms via the LXR/PI3K/Akt pathway.Methods 50 SD rats were selected to establish a coronary microcirculation disorder model and divided into sham,model and low/mid/high concentration lycopene groups.Left ven-tricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),left ventricular ejection fraction(LVEF)and left ventricular fractional shortening(LVFS)in rats were detected using echocardiography,creatine kinase(CK),lactate dehydrogenase(LDH),vascular endothelial growth factor(VEGF),platelet-derived growth factor(PDGF)were detected using ELISA,matrix metalloproteinase-9(MMP-9),matrix metalloproteinase-2(MMP-2)and PI3K/Akt pathway related protein expression were detected using Western blot,and liver X receptor α(LXRα)and liver X receptor β(LXRβ)expression were detected using immunohistochemical staining.In vitro,a hypoxia model of myo-cardial microvascular endothelial cells(MCMEC)was established,with groups including control,hypoxia,hypoxia+low/mid/high concentration lycopene,LXR/PI3K/Akt pathway inhibitor group and mitochondrial fission inhibitor group.Cell viability was detected using CCK-8,LXRα and LXRβ were detected using immunofluorescence,superoxide dismutase(SOD),reactive oxygen species(ROS),VEGF and PDGF levels were detected using ELISA,mitochondrial function-re-lated proteins(Drp1,Fis1,LC3-Ⅱ/LC3-Ⅰ,PINK1,Parkin and Opa1)and MMP-9,MMP-2 and PI3K/Akt pathway related proteins were detected using Western blot,and myocardial tissue injury was evaluated using HE staining.Results Compared with the sham group,the model group exhibited severe myocardial injury,with increased levels of LVEDD,LVESD,CK and LDH,decreased LVEF and LVFS,downregulated expression of VEGF,PDGF,MMP-9 and MMP-2,de-creased expression of p-PI3K/PI3K and p-Akt/Akt,and downregulated expression of LXRα and LXRβ.In cells,com-pared with the control group,the hypoxia group showed decreased cell viability,downregulated expression of VEGF,PDGF,MMP-9,and MMP-2,and decreased expression of p-PI3K/PI3K and p-Akt/Akt.Lycopene treatment could ef-fectively reverse the above changes and increase the expression of LXRα and LXRβ.Moreover,lycopene could also re-verse and modulate the characteristic alterations of Drp1,Fis1,LC3-Ⅱ/LC3-Ⅰ,PINK1,Parkin and Opa1 induced by LXR/PI3K/Akt pathway inhibitors or mitochondrial fission inhibitors.Conclusion Lycopene enhances mitochondrial activi-ty,reduces oxidative stress and improves myocardial microvascular remodeling by activating the LXR/PI3K/Akt pathway.

Objective To investigate the expression of non-receptor protein tyrosine phosphatase 18(PT-PN18)and RNA binding protein FOX2(RBFOX2)in endometrial cancer(EC),and to analyze their relation-ship with clinicopathological features and prognostic significance.Methods A total of 122 EC patients treated in Hainan Women and Children's Medical Center from January 2020 to June 2021 were collected.The expres-sion of PTPN18 and RBFOX2 protein was detected by immunohistochemistry.The expressions of PTPN18 mRNA and RBFOX2 mRNA were detected by real-time fluorescence quantitative PCR.Pearson correlation a-nalysis was used to analyze the correlation between PTPN18 mRNA and RBFOX2 mRNA expression in EC.Kaplan-Meier curve and multivariate Cox regression model were used to analyze the effect of PTPN18 mRNA and RBFOX2 mRNA expression on the prognosis of EC patients.Results Compared with adjacent tissues,PTPN18 protein expression(2.53±0.67 vs.0.56±0.14)was higher and RBFOX2 protein expression(0.74±0.22 vs.3.11±0.63)was lower in EC cancer tissues,and the difference was statistically significant(t=31.790,39.229,P<0.001).Compared with adjacent tissues,PTPN18 mRNA expression(3.15±0.76 vs.0.78±0.23)was higher and RBFOX2 mRNA expression(1.14±0.34 vs.3.87±0.80)was lower in EC cancer tissues,and the difference was statistically significant(t=32.976,34.689,P<0.001).There was a negative correlation between the expression of PTPN18 mRNA and RBFOX2 mRNA in EC(r=-0.674,P<0.001).The expression of PTPN18 mRNA was higher and RBFOX2 mRNA was lower in FIGO stage Ⅲ EC patients with lymph node metastasis(P<0.05).There was no significant difference in 3-year overall survival rate between PTPN18 mRNA high expression group and low expression group,and between RBFOX2 mRNA high expression group and low expression group(P>0.05).The 3-year progression-free survival rate of the PTPN18 mRNA high expression group was lower than that of the low expression group,and the 3-year pro-gression-free survival rate of the RBFOX2 mRNA high expression group was higher than that of the low ex-pression group,and the differences were statistically significant(P<0.001).FIGO stage Ⅲ,lymph node me-tastasis and PTPN18 mRNA were risk factors for progression-free survival in EC patients,and RBFOX2 mR-NA was a protective factor(P<0.05).Conclusion PTPN18 expression is increased and RBFOX2 expression is decreased in EC,which is related to FIGO stage and lymph node metastasis.PTPN18 is a tumor marker for evaluating the prognosis of EC.

Objective:To investigate lymph node metastasis(LNM)in the prostatic anterior fat pad(PAFP)of PCa patients after robot-assisted radical prostatectomy(RARP),and analyze the clinicopathological features and prognosis of LNM in the PAFP.Methods:We retrospectively analyzed the clinicopathological data on 1 003 cases of PCa treated by RARP in the Department of Urolo-gy of PLA General Hospital from January 2017 to December 2022.All the patients underwent routine removal of the PAFP during RARP and pathological examination,with the results of all the specimens examined and reported by pathologists.Based on the pres-ence and locations of LNM,we grouped the patients for statistical analysis,compared the clinicopathological features between different groups using the Student's t,Mann-Whitney U and Chi-square tests,and conducted survival analyses using the Kaplan-Meier and Log-rank methods and survival curves generated by Rstudio.Results:Lymph nodes were detected in 77(7.7％)of the 1 003 PAFP samples,and LNM in 11(14.3％)of the 77 cases,with a positive rate of 1.1％(11/1 003).Of the 11 positive cases,9 were found in the upgraded pathological N stage,and the other 2 complicated by pelvic LNM.The patients with postoperative pathological stage≥T3 constituted a significantly higher proportion in the PAFP LNM than in the non-PAFP LNM group(81.8％[9/11]vs 36.2％[359/992],P=0.005),and so did the cases with Gleason score ≥8(87.5％[7/8]vs 35.5％[279/786],P=0.009).No statisti-cally significant differences were observed in the clinicopathological features and biochemical recurrence-free survival between the pa-tients with PAFP LNM only and those with pelvic LNM only.Conclusion:The PAFP is a potential route to LNM,and patients with LNM in the PAFP are characterized by poor pathological features.There is no statistically significant difference in biochemical recur-rence-free survival between the patients with PAFP LNM only and those with pelvic LNM only.Routine removal of the PAFP and inde-pendent pathological examination of the specimen during RARP is of great clinical significance.

Objective To investigate the association between high-density lipoprotein cholesterol(HDL-C)levels and all-cause and cause-specific mortality in the elderly population,and to determine the optimal HDL-C concentration range associated with the lowest mortality risk.Methods This prospective cohort study included 16,632 elderly individuals aged≥60 years from the National Health and Nutrition Examination Survey(NHANES)between 1999 and 2018.Participants were divided into 5 groups based on HDL-C levels:<40 mg/dl group(n=2933),40-49 mg/dl group(n=4602),50-59 mg/dl group(n=3824),60-79 mg/dl group(n=3988),and≥80 mg/dl group(n=1285).Mortality data were obtained by linking records with the National Death Index(NDI).Cox proportional hazards regression and restricted cubic spline curves were used to analyze the association between HDL-C and mortality risk.Subgroup and sensitivity analyses were conducted.Results Multivariable-adjusted Cox models showed that,compared with 50-59 mg/dl HDL-C group,HDL-C<40 mg/dl group had significantly higher risks of all-cause mortality(HR=1.17,95%CI 1.05-1.31,P=0.006),cardiovascular mortality(HR=1.32,95%CI 1.08-1.58,P=0.001),and non-cardiovascular mortality(HR=1.14,95%CI 1.02-1.27,P=0.013).HDL-C≥80 mg/dl group had significantly higher risks of all-cause mortality(HR=1.18,95%CI 1.03-1.35,P=0.027)and non-cardiovascular mortality(HR=1.23,95%CI 1.03-1.46,P=0.029),but no significant effect on cardiovascular mortality(HR=1.07,95%CI 0.88-1.28,P=0.492).Restricted cubic spline curves revealed U-shaped associations between HDL-C and all-cause/non-cardiovascular mortality,and an inverse J-shaped association with cardiovascular mortality.These patterns were consistent in both elderly men and women.The HDL-C levels associated with the lowest risk were 56 mg/dl(95%CI 53-59 mg/dl)for all-cause mortality,54 mg/dl(95%CI 51-57 mg/dl)for cardiovascular mortality,and 59 mg/dl(95%CI 56-62 mg/dl)for non-cardiovascular mortality.Subgroup analyses showed no significant effect modifications.Sensitivity analyses confirmed the primary findings.Conclusions In the elderly population,extremely high HDL-C levels increase the risks of all-cause mortality and non-cardiovascular mortality,but do not elevate cardiovascular mortality.The risk of all-cause mortality is the lowest at an HDL-C concentration of 56 mg/dl.

Acute kidney injury (AKI) is a critical clinical condition characterized by rapid renal function decline, with high morbidity, mortality, and healthcare costs. Traditional Chinese medicine (TCM) has shown potential effects on mitigating oxidative stress and programmed cell death in AKI models. Scutellaria barbata D. Don (SB) and Scleromitrion diffusum (Willd.) R. J. Wang (SD), a classic TCM herbal pair exhibited anti-inflammatory and antioxidant activities. Using advanced chromatographic separation technology, we enriched the effective fractions of water extracts from SB-SD, obtaining self-assembled herbal nanoparticles (SB and SD nanoparticles, SSNPs) rich in flavonoids and terpenoids. These SSNPs demonstrated robust antioxidant properties in vitro and mitigated AKI progression in vivo by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Oral administration of SSNPs in mice resulted in absorption into the bloodstream, formation of a protein corona, reduced macrophage phagocytosis, and enhanced bioavailability and renal targeting. Furthermore, we investigated the self-assembly principle of SSNPs using representative flavonoids and terpenoids. Kinetic studies and in situ transmission electron microscopy (in situ TEM) revealed that these compounds self-assemble via supramolecular forces like hydrogen bonding and π-π interactions, forming stable nanostructures. This study elucidates the renoprotective effects and mechanisms of SB and SD, and provides a novel approach for the development of TCM-based nanomedicines, highlighting the potential of nano-TCM in AKI treatment.

Attention deficit hyperactivity disorder (ADHD), a prevalent neurodevelopmental disorder influenced by both genetic and environmental factors, remains poorly understood regarding how its polygenic risk score (PRS) impacts functional networks and symptomology. This study capitalized on data from 11,430 children in the Adolescent Brain Cognitive Development study to explore the interplay between PRS_ADHD, brain function, and behavioral problems, along with their interactive effects. The results showed that children with a higher PRS_ADHD exhibited more severe attention deficits and rule-breaking problems, and experienced sleep disturbances, particularly in initiating and maintaining sleep. We also identified the central executive network, default mode network, and sensory-motor network as the functional networks most associated with PRS and symptoms in ADHD cases, with potential mediating roles. Particularly, the impact of PRS_ADHD was enhanced in children experiencing heightened sleep disturbances, emphasizing the need for early intervention in sleep issues to potentially mitigate subsequent ADHD symptoms.
