Objective To investigate the effect of sakubatrotril and valsartan in the treatment of heart failure after percutaneous coronary intervention(PCI)for acute myocardial infarction(AMI).Methods AMI patients who received PCI were randomly divided into treatment group and control group.Both groups were given routine basic treatment such as anti-platelet aggregation,lipidregulation,β-blocker and diuretic tolasemide,while the control group was given enalapril maleate tablet(5 mg,bid).The treatment group was given sacubactril valsartan sodium tablets(5 mg,bid)in addition to basic treatment.The clinical efficacy,myocardial injury markers,cardiac function,ventricular remodeling indexes,vascular endothelial function and cardiovascular adverse events(MACEs)were compared between the two groups.Results The treatment group and the control group were enrolled in 40 patients.After 3 months of treatment,the total effective rate of the treatment group was 95.00％and that of the control group was 80.00％.The difference between the total effective rate of the treatment group and the control group was statistically significant(P＜0.05).After 3 months of treatment,the levels of creatine kinase isoenzyme(CK-MB)in treatment group and control group were(30.23±5.28)and(36.58±7.05)U·L-1,respectively;cardiac troponin Ⅰ(cTnⅠ)were(1.04±0.18)and(1.25±0.31)ng·mL-1,respectively;left ventricular ejection fraction(LVEF)were(40.29±6.32)％and(34.39±5.62)％,and endothelium-dependent diastolic function(FMD)were(15.72±2.83)％and(9.55±2.05)％,respectively;nitric oxide(NO)levels were(47.41±5.85)and(41.28±3.37)μmol·L-1;endothelin-1(ET-1)was(70.53±8.29)and(83.62±10.11)ng·L-1,respectively.Compared with the control group,the above indexes in treatment groups were statistically significant(all P＜0.05).The incidence of MACEs was 10.00％in treatment group and 25.00％in control group,with no statistical significance(P＞0.05).After 3 months of treatment,the incidence of adverse drug reactions in AMI patients in treatment group was 12.50％,and that in control group was 17.50％.There was no statistical significance in the incidence of adverse drug reactions in treatment group compared with control group(P＞0.05).Conclusion Sacubactril valsartan can effectively prevent ventricular remodeling and improve vascular endothelial function in patients with heart failure after PCI.

Research on inflammatory response,liver injury,and immune regulation has demonstrated that the intricate interactions among immune cells constitute a critical regulatory network.Alcohol consumption alters the liver microenvironment,triggering inflammation and immune responses.Elucidating the inhibitory,cooperative,and synergistic effects among lymphocytes and myeloid cells may reveal the core mechanisms of alcohol-associated liver disease(ALD)pathogenesis and identify promising therapeutic targets.This review seeks to elucidate the intricate and multifaceted interactions among immune cells,encompassing both direct cellular interactions and the secretion of various effector molecules.It is essential to underscore that these interactions have broader and more complex roles in ALD than the activities of individual immune cell types.These interactions play a crucial role in mutually regulating one another,thereby preserving the homeostasis of the inflammatory and immune response in the liver environment.Targeting these immune cell interactions is anticipated to offer a novel approach to the prevention and treatment of ALD.

Objective To investigate the activated phenotype and the expression of the receptor of advanced glycation endproducts(RAGE)of astrocytes after hypoxic-ischemic brain damage(HIBD)in neonatal rats and the effects of gastrodin(GAS)intervention on them.Methods Totally 48 neonatal 3 days SD rats were used to construct HIBD model and randomly divided into sham group,HIBD group and HIBD+GAS group(100 mg/kg),and the expressions of Al type astrocyte marker C3,A2 type astrocyte marker S100A10,RAGE,tumor necrosis factor-α(TNF-α),brain-derived neurotrophic factor(BDNF),and insulin-like growth factor(IGF-1)in the corpus callosum of the ischemic side were detected by Western blotting and immunohistochemical staining on day 1 and day 3 after HIBD.TNC-1 cells were divided into control group,oxygen glucose deprivation(OGD)group,OGD+GAS(0.34 mmol/L)group and GAS group,and then the protein expressions of RAGE,TNF-α,BDNF and IGF-1 were detected by Western blotting and immunofluorescence.Results In vivo,Western blotting showed that compared with the sham group,the protein expression levels of C3,S100A10,RAGE,TNF-α and IGF-1 in the 1 day and 3 days groups after HIBD group in 1 day group were significantly higher than those in the sham group(P＜0.05),but the protein expression level of BDNF decreased in 1 day group and increased in 3 days group(P＜0.05).Compared with the HIBD group,the C3,RAGE and TNF-α protein expression levels were significantly attenuated in the HIBD+GAS group(P＜0.05),and the protein expression levels of BDNF and IGF-1 further increased(P＜0.05).The protein expression of S100A10 in the 3 days group was higher than that in the HIBD group after GAS treatment(P＜0.05).The immunohistochemical staining results of C3,S100A10,and RAGE in the 1 day and 3 days groups after HIBD were consistent with Western blotting results.Furthermore,the protein expressions of RAGE and TNF-α were significantly enhanced in OGD-stimulated astrocytes(P＜0.05).After GAS intervention,while the expressions of both RAGE and TNF-α decreased significantly(P＜0.05),the expressions of BDNF and IGF-1 increased significantly(P＜0.05).Conclusion With inhibiting the up-regulation of RAGE signal in astrocyte after HIBD and expressions of A1 astrocyte and neuroinflammatory factors,gastrodin can promot the expressions of A2 astrocyte and nutritional factors,which play an important role in neuro-protective effect.

Objectives: In order to provide valuable information for the diagnosis and treatment of dermatitis, the prevalence rate and trend changes of common allergens in patients with allergic skin diseases in Beijing City were investigated and analyzed. Methods: This study was a retrospective data collection study. A total of 2 822 patients diagnosed with moderate to severe atopic dermatitis with allergen examinations were collected from Peking University First Hospital from 2017 to 2021, most of them were adults, and 83%(2 340/2 822) were over 18 years old. The ImmunoCAP fluorescent enzyme-linked immunoassay system was used to quantify specific IgE. The positive rate of each allergen was counted according to age, gender and year. The epidemiological characteristics and trends were analyzed. Results: In the past five years, 22 503 allergen-specific IgE test data were collected, and the positive rate of allergens in 40%(1 122/2 822) of the 2 822 patients was mainly multiple sensitization, the positive rate of allergens and multiple sensitization rates were the highest in people aged 13-18 years old. The 2 822 patients were dominated by inhaled allergens, and the highest positive rate was inhaled mixture (29.3%). The top five positive rates of inhaled allergens were Dermatophagoides farina (26.7%), Dermatophagoides pteronyssinus (25.5%), Mugwort (23.9%), Birch pollen (19.2%) and Siberian cocklebur (18.2%). The top five positive rates of food allergens were shrimp (15.2%), peanut (14.8%), sesame (14.7%), wheat (13.2%) and milk (13.1%). Analysis of the positive rate of allergens in different age groups showed except for the positive rate of birch pollen peaked at 3-12 years old, other inhaled allergens were the highest food allergens in 13-18 years old. Among food allergens, the positive rates of fx5, milk, egg and wheat were the highest in <3 years old, the positive rate decreased gradually with age, and the positive rate of other food allergens peaked at 13-18 years old, and the shrimp and crab was the highest in adult. The positive rate of various allergens in the 2 822 patients showed little difference between male and female and the male was slightly higher than female. In the past five years, the positive rate of allergens has been on the rise. The changes of inhaled allergens in cat/dog hair dander, Dermatophagoides farina and cicadas were large, while the positive rate of food allergens was stable. Conclusions: The etiology of the allergic skin diseases is complex, which may be related to allergen exposure, heredity, immunity, environmental factors, abnormal skin barrier function, etc. This study showed the distribution of allergens in patients with allergic skin diseases in Beijing City to a certain extent. It provided epidemiological data and clinical evidence for the prevention and treatment of allergic diseases.

Inductively coupled plasma mass spectrometry (ICP-MS) was applied to determine the concentrations of lead (Pb), cadmium (Cd) and arsenic (As) in Lindera aggregata (Sims) Kosterm. The physiologically based extraction test (PBET) digestion in vitro/Caco-2 cell model was established to investigate the bioaccessible contents of Pb, Cd and As in decoction of Lindera aggregata (Sims) Kosterm. The target-organ toxicity dose modification of HI method (TTD) was used to evaluate the cumulative risk caused by the combined exposure of the total levels of Pb, Cd and As in Lindera aggregata (Sims) Kosterm. and the bioaccessible contents in the decoction. The results showed that the total contents of Pb, Cd and As in 4 batches of samples were in the range of 2.901-3.872, 1.299-1.800 and 0.062-0.216 mg·kg^-1, respectively. After transportation by Cacco-2 cells, the bioaccessible contents of Pb, Cd, and As in the decoction were in the range of 0.045-0.080, 0.070-0.112 and 0.004-0.018 mg·kg^-1. The results of risk assessment showed that calculated by the total amounts of heavy metals in the Lindera aggregata (Sims) Kosterm., for the end points of nervous system, the cumulative risks of co-exposure of heavy metals in 3 batches of samples were of concern. After decoction and transportation by Caco-2 cells, for the end points of cardiovascular system, blood, nervous system, kidney and testis, the TTD modification of HI values of all batches of samples were less than 1, and the health risks were acceptable. The study provided methodology basis for a more objective assessment of the health risks of heavy metals and harmful elements in traditional Chinese medicine and for a more scientific limit standard of heavy metals and harmful elements.

OBJECTIVE: To evaluate the safety and efficacy of catheter-directed thrombolysis (CDT) versus systemic thrombolysis (ST) in the treatment of pulmonary embolism (PE). METHODS: The Cochrane Library, PubMed, and Embase databases were searched to collect the literature on the comparison of the results of CDT and ST in the treatment of PE from the beginning of their records to May 2020, and meta-analysis was performed by STATA software (version 15.1). Using standardized data-collection forms, the authors screened the studies and independently extracted data, and assessed the quality of the studies using the Newcastle-Ottawa Scale for cohort studies. Cohort studies that examined the following results were included in the current study: in-hospital mortality, all-cause bleeding rate, gastrointestinal bleeding rate, intracranial hemorrhage rate, the incidence of shock, and hospital length of stay. RESULTS: A total of eight articles, with 13,242 participants, involving 3962 participants in the CDT group and 9280 participants in the ST group were included. CDT compared with ST in the treatment of PE can significantly affect in-hospital mortality rate [odds ratio (OR) = 0.41, 95% CI: 0.30-0.56, P < 0.05], all-cause bleeding rate (OR = 1.20, 95% CI: 1.04-1.39, P = 0.012), gastrointestinal bleeding rate (OR = 1.43, 95% CI: 1.13-1.81, P = 0.003), the incidence of shock (OR = 0.46, 95% CI: 0.37-0.57, P < 0.05), and hospital length of stay [standard mean difference (SMD) = 0.16, 95% CI: 0.07-0.25, P < 0.05]. However, there was no significant effect on intracranial hemorrhage rate in patients with PE (OR = 0.70, 95% CI: 0.47-1.03, P = 0.070). CONCLUSIONS CDT is a viable alternative to ST in the treatment of PE, as it can significantly reduce in-hospital mortality rate, all-cause bleeding rate, gastrointestinal bleeding rate, and incidence of shock. However, CDT may prolong hospital length of stay to a certain extent. Further research is needed to evaluate the safety and efficacy of CDT and ST in the treatment of acute PE and other clinical outcomes.

Age-dependent loss of skeletal muscle mass and function is a feature of sarcopenia, and increases the risk of many aging-related metabolic diseases. Here, we report phenotypic and single-nucleus transcriptomic analyses of non-human primate skeletal muscle aging. A higher transcriptional fluctuation was observed in myonuclei relative to other interstitial cell types, indicating a higher susceptibility of skeletal muscle fiber to aging. We found a downregulation of FOXO3 in aged primate skeletal muscle, and identified FOXO3 as a hub transcription factor maintaining skeletal muscle homeostasis. Through the establishment of a complementary experimental pipeline based on a human pluripotent stem cell-derived myotube model, we revealed that silence of FOXO3 accelerates human myotube senescence, whereas genetic activation of endogenous FOXO3 alleviates human myotube aging. Altogether, based on a combination of monkey skeletal muscle and human myotube aging research models, we unraveled the pivotal role of the FOXO3 in safeguarding primate skeletal muscle from aging, providing a comprehensive resource for the development of clinical diagnosis and targeted therapeutic interventions against human skeletal muscle aging and the onset of sarcopenia along with aging-related disorders.
