Objective To investigate the effect of tritiated water on the immune system of zebrafish and its potential molecular mechanism. Methods Zebrafish embryos (2.5 to 3 hours post-fertilization [hpf]) were exposed to 3.7 × 10⁴ Bq/mL tritiated water (tritiated water group), and those exposed to E3 culture medium were used as the control group. The mortality rate, hatching rate, deformity rate, heart rate, body length, yolk sac area, neutrophil count in the tail, immune-related gene expression, and immune-related protein expression of zebrafish in the two groups were determined. Then transcriptome technology was used to further analyze the possible mechanism of tritiated water affecting the immune system of zebrafish. Results Compared with the control group, zebrafish at 72 hpf in the tritiated water group had no significant changes in the mortality rate, hatching rate, deformity rate, body length, and yolk sac area((t = 0.9045, 0.5000, 1.0000, 0.7238, 0.0337, P = 0.4169, 0.6433, 0.3739, 0.4785, 0.9735), but had significantly increased heart rate(t = 4.575，P = 0.002). At 4 days post-fertilization (dpf), the neutrophil count in the tail of zebrafish in the tritiated water group was significantly increased(t = 2.563，P = 0.0196), the mRNA expression of TNF-α was significantly decreased(t = 2.891, P = 0.045), the protein expression of nuclear factor-kappa B (NF-κB) was significantly increased(t = 3.848, P = 0.018), and the protein expression of NLRP3 was significantly decreased(t = 14.98, P = 0.001). At 7 dpf, the neutrophil count in the tail and the protein expression levels of NF-κB, NLRP3, and interleukin-1β were significantly decreased(t = 3.772, 7.048, 15.620, 4.423, P = 0.014, 0.002, 0.0001, 0.012). Transcriptome sequencing revealed that differentially expressed genes were mainly enriched in the “neutrophil activation” and “platelet activation pathways” at 4 dpf and in the “neutrophil apoptosis”, “ferroptosis”, and “necroptosis” pathways at 7 dpf. Conclusion Tritiated water exposure induces a temporally dynamic immune response in zebrafish, potentially affecting immune homeostasis by regulating neutrophil activation and apoptosis, as well as the expression of NF-κB and NLRP3.

OBJECTIVE: To assess the efficacy of Qingda Granule (QDG) in ameliorating hypertension-induced cardiac damage and investigate the underlying mechanisms involved. METHODS: Twenty spontaneously hypertensive rats (SHRs) were used to develope a hypertension-induced cardiac damage model. Another 10 Wistar Kyoto (WKY) rats were used as normotension group. Rats were administrated intragastrically QDG [0.9 g/(kg•d)] or an equivalent volume of pure water for 8 weeks. Blood pressure, histopathological changes, cardiac function, levels of oxidative stress and inflammatory response markers were measured. Furthermore, to gain insights into the potential mechanisms underlying the protective effects of QDG against hypertension-induced cardiac injury, a network pharmacology study was conducted. Predicted results were validated by Western blot, radioimmunoassay immunohistochemistry and quantitative polymerase chain reaction, respectively. RESULTS: The administration of QDG resulted in a significant decrease in blood pressure levels in SHRs (P<0.01). Histological examinations, including hematoxylin-eosin staining and Masson trichrome staining revealed that QDG effectively attenuated hypertension-induced cardiac damage. Furthermore, echocardiography demonstrated that QDG improved hypertension-associated cardiac dysfunction. Enzyme-linked immunosorbent assay and colorimetric method indicated that QDG significantly reduced oxidative stress and inflammatory response levels in both myocardial tissue and serum (P<0.01). CONCLUSIONS Both network pharmacology and experimental investigations confirmed that QDG exerted its beneficial effects in decreasing hypertension-induced cardiac damage by regulating the angiotensin converting enzyme (ACE)/angiotensin II (Ang II)/Ang II receptor type 1 axis and ACE/Ang II/Ang II receptor type 2 axis.

Objective:To investigate the impact of QiliQiangXin Capsules on ventricular remodeling and cardiac contraction and relaxation function in aging rats with heart failure following myocardial infarction.Methods:From August 2022 to August 2023, a total of 30 old rats were randomly assigned to three groups: sham-operated group, model group, and treatment group, with 10 rats in each group selected through a digital lottery method.The model and treatment groups were created by ligating the anterior descending branch of the left coronary artery.The rats in the treatment group received daily administration of Astragalosa hebecarpa Drabanemerosa Strong Heart Capsule(1.0 g/kg)via gavage after 4 weeks.After the 4-week drug administration period, echocardiography was performed to measure various parameters including left ventricular end-diastolic internal diameter(LVIDd), left ventricular end-systolic internal diameter(LVIDs), left ventricular ejection fraction(LVEF), left ventricular anterior wall myocardial thickness(LVAWd), mitral valve early diastolic peak flow velocity(E peak), and early diastolic velocity of mitral annulus(e peak)detected by tissue Doppler(TDI). The E/e value was calculated based on these measurements.Additionally, serum levels of B-type brain natriuretic peptide(BNP), matrix metalloproteinase 2(MMP-2), matrix metalloproteinase 9(MMP-9), and tumor necrosis factor(TNF-α)were measured using enzyme-linked immunosorbent assay(ELISA). Hematoxylin-eosin(HE)staining was employed to observe the morphological changes in myocardial tissue.Results:Compared to rats in the model group, rats in the treatment group exhibited lower left ventricular internal dimension at end-diastole(LVIDd)(9.1±0.6 mm vs.11.4±0.8 mm, P<0.01), lower left ventricular internal dimension at end-systole(LVIDs)(5.9±0.8 mm vs.8.7±0.9 mm, P<0.01), lower E/e ratio(13.4±2.0 vs.16.3±2.8, P<0.05), higher left ventricular ejection fraction(LVEF)(68.8±7.1% vs.52.0±8.4%, P<0.01), and elevated left ventricular anterior wall thickness at end-diastole(LVAWd)(1.5±0.2 mm vs.1.2±0.3 mm, P<0.05). In addition, compared to rats in the model group, the treatment group showed a decrease in brain natriuretic peptide(BNP)(0.26±0.04 μg/L vs.0.34±0.05 μg/L, P<0.01), decreased matrix metalloproteinase-2(MMP-2)(3697.0±857.7 μg/L vs.4719.5±703.5 μg/L, P<0.01), decreased matrix metalloproteinase-9(MMP-9)(87.3±13.8 μg/L vs.116.5±9.6 μg/L, P<0.01), decreased tumor necrosis factor-alpha(TNF-α)(165.3±36.9 μg/L vs.269.8±35.0 μg/L, P<0.01), and lower TNF-α levels(165.3±36.9 μg/L vs.269.8±35.0 μg/L, P<0.01). Histological examination using hematoxylin and eosin(HE)staining revealed that the treatment group had less severe cardiac myocyte arrangement disorder and inflammatory reaction compared to the model group. Conclusions:Qiliqiangxin Capsules were found to effectively delay ventricular remodeling and improve myocardial contraction and relaxation function in aging rats with heart failure after acute myocardial infarction.

Autism spectrum disorder(ASD)is a pervasive neurodevelopmental disorder with onset in infancy or early childhood.Mendelian randomization(MR)is a statistical method used to infer causal relationships between exposures and outcomes.This article summarizes MR studies related to ASD.Existing research supports a causal relationship between maternal inflammatory bowel disease in children with ASD,parental education levels,screen time exposure,obesity,insomnia,serum transferrin,decreased blood selenium,abnormal signals in brain functional MRI,interleukin-6,phosphodiesterase 2A,mitogen-activated protein kinase kinase 3,mitochondrial ribosomal protein L33,serotonin,and ASD.However,it does not support a causal relationship between parental rheumatoid arthritis,systemic lupus erythematosus,neonatal jaundice in children with ASD,cytomegalovirus infection,asthma,oral ulcers,vitamin D levels,and ASD.This article reviews the etiological factors related to ASD and MR studies,aiming to explore and deepen the understanding of the pathophysiology of ASD.It provides strong statistical support for the prevention,diagnosis,and treatment of ASD,and offers new methods and strategies for the etiological analysis of complex traits.

Objective:To explore the current situation of maternal childbirth readiness and analyze its influencing factors, providing a basis for improving maternal childbirth readiness.Methods:From March to July 2023, convenience sampling was used to select 355 pregnant women who visited Obstetrics Clinic in three Class Ⅲ Grade A hospitals in Chengde City, Hebei Province as participants. Participants were surveyed using the self-designed General Information Questionnaire, Childbirth Readiness Scale, Perceived Social Support Scale, Family APGAR Index, and Childbirth Self-efficacy Inventory 32. LASSO regression and random forest importance ranking were used to select characteristic variables, and multiple linear regression was combined to enhance interpretability, so as to explore the important factors affecting maternal childbirth readiness.Results:The total score of the Childbirth Readiness Scale for 355 pregnant women was (74.41±7.09), and the mean score of each item was (4.13±0.39). The random forest algorithm showed that when the lambda (λ) value was 0.167 7, the error was minimized, and the corresponding number of influencing factors was six. The top six independent variables in importance ranking were perceived social support, childbirth self-efficacy, gestational week, primiparous status, participation in maternity school, and place of residence. Multiple linear regression analysis showed that perceived social support, childbirth self-efficacy, whether primigravida, gestational week, and participation in maternity school were important influencing factors of maternal childbirth readiness ( P<0.05) . Conclusions:The childbirth readiness of pregnant women is above the middle level. Medical and nursing staff can start with factors that affect the childbirth readiness of pregnant women, adopt personalized nursing measures for pregnant women with different characteristics, and encourage family members to provide sufficient family support to improve the readiness of pregnant women for childbirth.

The PRR11 gene (Proline Rich 11) has been implicated in lung cancer; however, relationship between PRR11 and immune infiltration is not clearly understood. In this study, we used The Cancer Genome Atlas (TCGA) data to analyze the lung adenocarcinoma patients; PRR11 gene expression, clinicopathological findings, enrichment, and immune infiltration were also studied. PRR11 immune response expression assays in lung adenocarcinoma (LUAD) were performed using TIMER, and statistical analysis and visualization were conducted using R software. All data were verified using Gene Expression Profiling Interactive Analysis (GEPIA), and the Human Protein Atlas (HPA). We found that PRR11 was an important prognostic factor in patients with LUAD. PRR11 expression was correlated with tumor stage and progression. Gene Set Enrichment Analysis (GSEA) showed that PRR11 was enriched in the cell cycle regulatory pathways. Immune infiltration analysis revealed that the number of T helper 2 (Th2) cells increased when PRR11 was overexpressed. These results confirm the role of PRR11 as a prognostic marker of lung adenocarcinoma by controlling the cell cycle and influencing the immune system to facilitate lung cancer progression.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.

Objective To explore the effect of Yiqi Tongluo Anshen Recipe combined with statins on coronary blood flow and blood pressure in patients with coronary heart disease complicated with hy-pertension.Methods A total of 120 patients with coronary heart disease combined with hypertension were selected as study objects,and were divided into two groups according to treatment methods,with 60 patients in each group.The conventional group was treated with amlodipine tablets combined with atorvastatin calcium tablets,and the Anshen prescription group was treated with Yiqi Tongluo Anshen Recipe on the basis of the conventional group.The levels of Salusin-β,lipoprotein-associated phospho-lipase A2(LP-PLA2),high-sensitivity C-reactive protein(hs-CRP),pentamylin 3(PTX3),tumor necrosis factor-α(TNF-α)and blood pressure of the two groups were recorded before and after treat-ment,and the TIMI3 rate of coronary blood flow in myocardial infarction thrombolysis test(TIMI)and the adverse reaction rate during treatment were analyzed.Results The total effective rate of TCM syn-drome in the Anshen prescription group was higher than that in conventional group(P＜0.05).After treatment,systolic blood pressure(SBP)and diastolic blood pressure(DBP)in two groups were lower than before treatment,and SBP and DBP in the Anshen prescription group were lower than those in the conventional group(P＜0.05).The rate of coronary blood flow TIMI3 in the Anshen prescrip-tion group was higher than that in the conventional group(P＜0.05).After treatment,levels of Sa-lusin-β,LP-PLA2,PTX3,hs-CRP and TNF-α in two groups were decreased compared with those before treatment,and levels of Salusin-β,LP-PLA2,PTX3,hs-CRP and TNF-α levels of in the Anshen prescription group after treatment were lower than those in the conventional group(P＜0.05).There was no significant difference in the incidence of adverse reactions between the Anshen prescription group and the conventional group(P＞0.05).Conclusion Yiqi Tongluo Anshen Recipe combined with statins in the treatment of coronary heart disease with hypertension can reduce the expression of related factors,improve coronary blood flow and the curative effect.
