Objective To investigate the effects of evolocumab in the early postoperative period after percutaneous coronary intervention(PCI)on blood lipids and inflammatory cytokines in the patients with ul-tra-high-risk atherosclerotic cardiovascular disease(ASCVD).Methods A total of 65 patients with ultra-high-risk ASCVD treated by PCI in this hospital from October 2022 to March 2023 were selected as the study subjects and divided into the observation group(n=33)and control group(n=32)according to the used drugs.The patients in the control group received the treatment of oral rosuvastatin 10 mg;on the basis of the treatment in the control group,the observation group was treated with subcutaneous injection of evolocumab 140 mg immediately after PCI.The fasting blood samples were collected before surgery,on postoperative 3 d,1,3,6 months,and the levels of inflammation and blood lipid indexes were detected and recorded.The occur-rences of cardiovascular adverse events(MACE)and other complications in postoperative 6 months were re-corded.Results The levels of LDL-C,Lp-PLA2 and lipoprotein a on postoperative 3 d,1,3,6 months in the observation group were gradually decreased,moreover were lower than those in the control group,and the differences were statistically significant(P<0.05).The levels of IL-6,homocysteine and hs-CRP on postoper-ative 3 d,1,3,6 months in the two groups were decreased,moreover the levels of various indexes in the obser-vation group were lower than those in the control group,and the differences were statistically significant(P<0.05).The incidence rate of MACE in the observation group was lower than that in the control group,and the difference was statistically significant(P<0.05);the difference in the incidence rates of other complications between the two groups was not statistically significant(P>0.05).According to the Log Rank test,the sur-vival rate of the observation group was higher than that of the control group,and the difference was statistical-ly significant(P<0.05).Conclusion The early application of evolocumab after PCI could reduce the blood lipid level and inflammatory cytokines levels of the patients with ultra-high-risk ASCVD,and increase their survival rate.

Objective To investigate the current status of frailty in lung cancer patients undergoing radiotherapy and analyze its influencing factors.Methods The convenience sampling method was used to select 241 lung cancer patients admitted to the radiation therapy department of a tertiary Grade A tumor specialty hospital in Yunnan Province from January to December 2023.A questionnaire survey was conducted using the General Information Survey Questionnaire,Fried Weakness Scale,Anderson Symptom Assessment Scale(MDASI),Hospital Anxiety and Depression Scale(SDS),Nutrition Risk Screening 2002,and Barthel Index Scale.Results The frailty in lung cancer patients undergoing radiotherapy was 55.19%,with a total frailty score of 3.00(1.00,4.00)points.The results of logistic regression analysis showed that age,number of radiotherapy sessions,hemoglobin count,Barthel index,Anderson symptom assessment score,and anxiety score were the influencing factors of frailty in lung cancer patients undergoing radiotherapy(P<0.05).Conclusion The incidence of frailties in patients with lung cancer radiotherapy is high.Age,radiotherapy frequency,hemoglobin count,Barthel index,Anderson symptom rating and anxiety score are the factors affecting frailties in patients with lung cancer radiotherapy.Clinical medical staff should promptly evaluate the frailty of lung cancer radiotherapy patients and identify their risk factors,and actively take intervention measures to prevent or control the occurrence and development of frailty.

Objective To systematically evaluate the qualitative studies on the care experience of caregivers for primary malignant bone tumors patients,in order to provide references for the construction of bone tumor support care system.Methods The Cochrane Library,PubMed,Embase,CNKI,Wanfang Database,VIP database,and China Biomedical Literature Database were searched by computer to collect qualitative studies on the care experience of caregivers of malignant bone tumors patients from the establishment of the databases to November 2022.The quality of the literature was evaluated using the Joanna Briggs Institute(JBI)Quality Evaluation Criteria for Quality Research in Evidence-Based Health Care Centers(2016),and the results were integrated by a pooled integration approach.Results A total of 12 studies were included;48 themes were extracted and summarized into 9 categories,which were combined into 3 integrated results.Integration result 1 is obvious physical and mental disturbance.Integration result 2 is multiple role maladaptation.Integration result 3 is positive growth after adjustment.Conclusion Caregivers of patients with malignant bone tumors have serious physical and mental burden and are eager for multiple support.It is suggested that medical staff pay attention to the multi-dimensional needs of patients,formulate personalized support strategies,help caregivers adapt and transform their roles,and promote the post-traumatic growth of caregivers.

Objective: To explore the effect of mindfulness traits on sleep quality of college students, and to investigate the mediating mechanism of cognitive emotion regulation and anxiety for mindfulness trait factors, and sleep quality in college students. Methods: Totally 397 college students from five colleges were investigated using Five Facet Mindfulness Questionnaire, Cognitive Emotion Regulation Questionnaire, Self-Rating Anxiety Scale and Pittsburgh Sleep Quality Index.SPSS 22.0 version and Bootstrap method were used to analysis data and test intermediate effect. Results: (1)The total score of mindfulness trait and the score of describe, act with awareness and non-judge factors in mindfulness traits were(118.44±9.38), (24.82±3.87), (27.41±5.53) and (25.07±4.60), respectively.The total score of sleep quality was (5.57±2.62), and it was negatively related to the above three factors (r=-0.13--0.37, all P<0.05). (2)Anxiety played a complete mediating role between describe factor and sleep quality.Negative cognitive emotion regulation and anxiety played multiple mediating roles between the total score of mindfulness trait, the act with awareness factor and sleep quality.Negative cognitive emotion regulation and anxiety played a complete chain mediated role between non-judge factor and sleep quality. Conclusion The describe, act with awareness and non-judge factors in mindfulness traits can affect sleep quality through mediation of negative cognitive emotion regulation and / or anxiety.

Deregulation of endothelial nitric oxide synthase (eNOS) plays an important role in the development of multiple cardiovascular diseases. Our recent study demonstrated that genistein supplementation attenuates pulmonary arterial hypertension in broilers by restoration of endothelial function. In this study, we investigated the molecular mechanism by using broiler pulmonary arterial endothelial cells (PAECs). Our results showed that genistein stimulated a rapid phosphorylation of eNOS at Ser(1179) which was associated with activation of eNOS/NO axis. Further study indicated that the activation of eNOS was not mediated through estrogen receptors or tyrosine kinase inhibition, but via a phosphatidylinositol 3-kinase (PI3K)/Akt-dependent signaling pathway, as the eNOS activity and related NO release were largely abolished by pharmacological inhibitors of PI3K or Akt. Thus, our findings revealed a critical function of Akt in mediating genistein-stimulated eNOS activity in PAECs, partially accounting for the beneficial effects of genistein on the development of cardiovascular diseases observed in animal models.
