Objective To investigate th effect of PCSK9 inhibitors on early intensive lipid-lowering therapy in patients with symptomatic intracranial atherosclerotic stenosis(ICAS).Method One hundred and thirty-nine symptomatic ICAS patients who attended the Xuzhou Central Hospital from October 2022 to August 2023 were collected.According to the choice of lipid-lowering regimen,they were divided into statin drug group(n=54),PCSK9 inhibitor group(n=42)and combination drug group(n=43).Baseline data,laboratory indices,adverse drug reactions,clinical neurological function scores and endpoint events of the three groups were collected and analyzed.Results There was no statistically significant difference in the clinical data among the three groups before treatment.Compared with pre-treatment,total cholesterol(TC)and low-density lipoprotein cholesterol(LDL-C)levels were significantly lower in the three groups after treatment(all P＜0.01),and peripheral blood leukocyte counts were significantly lower in the PCSK9 inhibitor group after treatment(P＜0.05).After treatment,the differences in TC and LDL-C levels and the proportions of LDL-C＜1.8 mmol/L after 2 weeks of medication and LDL-C＜1.4 mmol/L on the 90th day were statistically significant among the three groups(all P＜0.01).Compared with the statin drug group,the differences in TC and LDL-C levels and the proportions of LDL-C＜1.8 mmol/L after 2 weeks and LDL-C＜1.4 mmol/L on the 90th day in the PCSK9 inhibitor group and the combination drug group were statistically significant(all P＜0.05).The differences in the occurrence of endpoint events,the proportion of recurrent AIS or TIA,cardiovascular events,and the time to endpoint events among the three groups were statistically significant on the 180th day after treatment(all P＜0.05).Differences in the occurrence of endpoint events,proportion of cardiovascular sexual events,and time to endpoint events on day 180 after treatment were statistically different in the PCSK9 inhibitor group and the combination drug group compared with the statin drug group(all P＜0.05).There was a statistically significant difference among the survival analysis curves of the three groups,with higher event-free survival in both groups with PCSK9 inhibitors alone or in combination(Log-Rank=13.95,P=0.0009).Conclusion Early intensive lipid lowering with PCSK9 inhibitors is effective and safe in patients with symptomatic ICAS,and can further reduce LDL-C,TC,and white blood cell counts,as well as improve lipid compliance,and significantly reduce the rate of end-point events with a significantly prolonged time to occurrence.

Compassion is an important part of nurses'professional quality,and it is also the basis of effective nurse-patient communication and humanistic care.Improving nurses'compassion is helpful to provide high-quality nursing services to patients.This study reviews the definition of compassion,the factors affecting compassion and the training methods to improve compassion,analyzes the shortcomings of existing training methods,and puts forward the prospects for future research,so as to provide a theoretical foundation for future compassion training among nurses.

Objective To analysis the effectiveness and cost of Internet-based anticoagulation clinic versus traditional anticoagulation clinic treatment at Nanjing Drum Tower Hospital during the COVID-19 pandemic.Methods We reviewed and analyzed the clinical data of patients receiving anticoagulation management through Internet-based outpatient care and traditional outpatient care in Nanjing Drum Tower Hospital,from June 1,2020 to June 30,2021.Variability in time in therapeutic range(TTR)and international normalized ratio(INR)were calculated for enrolled patients.Patients meeting TTR≥60%and INR variability<0.65 were considered optimal anticoagulation quality.Cost-effectiveness analysis was conducted from the patients'perspective,with results expressed using the incremental cost-effectiveness ratio(ICER).Results In the"Internet-based anticoagulation outpatient care"and"traditional face-to-face anticoagulation outpatient care"groups,19 individuals(67.86%)and 67 individuals(76.14%)met the criteria for optimal anticoagulation quality,respectively.The mean TTR was(71.83±19.17)%in the Internet-based group and(71.74±23.41)%in the traditional face-to-face group,indicating similar levels of warfarin anticoagulation quality between the two groups.The ICER was calculated as 327.17 yuan,less than the per capita gross domestic product(GDP)of 2021.Conclusion During the COVID-19 pandemic,Nanjing Drum Tower Hospital's Internet-based anticoagulation outpatient care effectively complemented the government's epidemic control policies.It ensured equivalent anticoagulation outcomes and significantly reduced patients'financial burdens.This approach offers new insights and guidance for optimizing healthcare services in the post-pandemic era.
