Objective:To explore the predictive value of Epinephrine (EPI) level for Major adverse cardiovascular events (MACE) in patients with ST segment elevation myocardial infarction (STEMI) after emergency Percutaneous coronary intervention (PCI).Methods:A total of 107 patients with STEMI after emergency PCI in Northern Jiangsu People's Hospital of Jiangsu Province from September 2020 to November 2021 were selected. Baseline data, biochemical test data and coronary angiography data were collected. EPI level was measured by enzyme-linked immunosorbent assay. The following analysis was planned: ① Patients were divided into MACE group and non-MACE group, and various indicators of the two groups were compared; ② According to Receiver operating characteristic curve (ROC), the best cut-off values of EPI level which predict the occurrence of MACE were calculated respectively. Patients were respectively divided into high EPI level group and low EPI level group according to the best cut-off values, and the occurrence of MACE between the groups was compared respectively.③ Survival analysis (Kaplan-Meier method and log-rank test) was used to investigate the relationship between EPI level and MACE in patients with STEMI after emergency PCI. ④COX proportional hazard regression model was used to investigate the risk factors for MACE in patients with STEMI after emergency PCI.Results:①According to the inclusion and exclusion criteria, 107 patients with STEMI after emergency PCI were selected for the study, of which 19 patients had MACE and 88 patients did not have MACE. Compared with the non-MACE group, the patients in the MACE group were older, the proportion of Killip Ⅱ and above, NT-proBNP and EPI were higher, while FT3 was lower, and the differences were statistically significant ( P<0.05). The Gensini score of MACE group was significantly higher than that of non-MACE group ( P<0.01). ② According to ROC analysis, the Area under the curve (AUC) of EPI level for predicting MACE in patients with STEMI after emergency PCI was 0.699 (95% CI: 0.579-0.819, P=0.007), the best cut-off value of EPI level was 528.54, the sensitivity was 78.9%, and the specificity was 56.8%. The incidence of MACE in the high EPI level group was significantly higher than that in the low EPI group ( P=0.005).③ Kaplan-Meier survival curve showed that the higher the EPI level value, the higher the risk of MACE (log-rank test P=0.004). ④Multivariate COX regression analysis showed that age ( P=0.042), FT3 ( P<0.001), EPI level ( P<0.001) and Gensini score ( P=0.004) were independent risk factors for MACE. Conclusions:①EPI level significantly correlates with the occurrence of MACE in patients with STEMI after emergency PCI. EPI level has predictive value for MACE in patients with STEMI after emergency PCI. The higher the EPI value, the higher the risk of MACE. ②Multivariate COX regression analysis show that EPI level is independent risk factor for MACE in patients with STEMI after emergency PCI.

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 investigate the distribution differences of cytochrome P4502C19(CYP2C19)gene polymorphisms and its impact on antiplatelet therapy in patients with coronary arter-y disease undergoing percutaneous coronary intervention(PCI)in Yangzhou region.Methods A to-tal of 215 patients diagnosed with coronary heart disease who underwent PCI from January 2021 to De-cember 2022 in Yangzhou region were retrospectively selected as study objects.The age of the pa-tients ranged from 37 to 93 years,with 152 males and 63 females.Polymerase chain reaction-sequen-cing was used to detect the CYP2C19 genotypes in the patients.The relationships of gender and age with distribution of CYP2C19 gene polymorphism were observed.Based on the metabolic types of CYP2C19 and the antiplatelet drugs used post-operatively,the patients were divided into fast-metabo-lizing clopidogrel group,medium-slow metabolizing clopidogrel group,fast-metabolizing ticagrelor group,medium-slow metabolizing ticagrelor group.After 6 months of follow-up,the incidence rates and severity of adverse events of cardiovascular ischemia and bleeding were compared among groups.Results The CYP2C19 genotypes of 215 patients were distributed as follows:81 cases of CYP2C19*1/*1 genotype,93 cases of CYP2C19*1/*2,10 cases of CYP2C19*1/*3,25 cases of CYP2C19*2/*2,6 cases of CYP2C19*2/*3.CYP2C19 metabolite types were fast metabolizers in 81 cases(37.67％),intermediate metabolizers in 103 cases(47.91％)and slow metabolizers in 31 cases(14.42％).The proportion of extensive metabolizers of CYP2C19 in the study patients was 37.67％,intermediate metabolizers accounted for 47.91％,and poor metabolizers accounted for 14.42％.There was no significant difference in the distribution of CYP2C19 genotype between different genders(x2=0.346,P=0.987).There was no significant difference in the distribution of metabolic type between different genders(x2=0.342,P=0.843).There was no significant differ-ence in the distribution frequency of metabolic type among different age groups(x2=1.098,P=0.895).The incidence of cardiovascular ischemia of adverse events in the fast-metabolizing clopi-dogrel group and the fast-metabolizing ticagrelor group was 16.67％and 14.29％,respectively,no significant difference was observed(P＞0.05).The incidence of cardiovascular ischemia of adverse events in the medium-slow metabolized clopidogrel group was higher than that in the medium-slow metabolized ticagrelor group,and the difference was statistically significant(P＜0.05).There was no significant between-group difference in the incidence of bleeding of adverse events among groups(P＞0.05).Conclusion In patients undergoing PCI for coronary heart disease in Yangzhou re-gion,there is a polymorphism in the CYP2C19 gene with no significant differences between genders and age groups.The intermediate and fast metabolizers are more prevalent.It is clinically significant to perform CYP2C19 gene testing and adopt precise antiplatelet therapy for such patients.

Atrial fibrillation(AF)is one of common arrhythmia,which is associated with lower quality of life,decreased heart function,and reduced survival rate.Currently,the treatment of AF focuses on improving symptoms,reducing the incidence of complications and mortality,as well as de-creasing emergency department visit or hospitalization related to AF.Percutaneous left atrial append-age closure(LAAC)can reduce the risk of stroke in non-valvular atrial fibrillation(NVAF)patients,and is an effective alternative to oral anticoagulant therapy.This study reported the successful thera-peutic process of LAAC in a patient with persistent AF and coexisting coronary heart disease,and the preoperative transesophageal echocardiography(TEE)showed a complex multi-lobed left atrial append-age,so the LAmbre occluder with small umbrella and large cover design was selected for treatment.
