Aim To apply coronary angiography derived index of microcirculatory resistance(caIMR)to evaluate the effect of coronary microcirculation perfusion on myocardial remodeling after interventional therapy in patients with acute anterior ST segment elevation myocardial infarction(STEMI).Methods This was a cross-sectional study.The analysis was performed among the patients who were hospitalized for acute anterior STEMI in the First Department of the Second Affiliated Hospital of Dalian Medical University from January 2021 to July 2022 and received percutaneous coro-nary intervention(PCI)with regtelar follow-up visits.The patients were divided into low caIMR(L-caIMR)group,me-dium caIMR(M-caIMR)group and high caIMR(H-caIMR)group according to the results of caIMR.The results of ech-ocardiography at perioperative period,1 month,3 months,6 months and 1 year were analyzed and compared,including left atrial diameter(LAD),left ventricular end-diastolic diameter(LVEDD),interventricular septum thickness(IVST),mitral orifice flow velocity E/A,mitral annular septum e'and mitral annular wall e',etc.The difference of interleukin-1β(IL-1β),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α)and other inflammatory factors in peripheral blood of the three groups were also compared.Results A total of 75 patients diagnosed with acute anterior STEMI were recrui-ted,including 55 males.The L-caIMR group,M-caIMR group,and H-caIMR group had 26,26 and 23 cases,respec-tively.Compared with the L-caIMR group,the LAD and IVST in the M-caIMR group and the H-caIMR group exhibited an increasing tendency one month after PCI,and the increase in the H-caIMR group was more significant than that in the M-caIMR group(P＜0.05).The ejection fraction in the H-caIMR group was notably lower than that in the L-caIMR group and the M-caIMR group at 1 and 3 months after PCI(P＜0.05).Compared with the L-caIMR group,the mitral flow velocity E/A at 6 months after PCI,and the e'at the septal side and the lateral wall of the mitral annulus at 1,3,and 6 months after PCI were significantly reduced in the M-caIMR and H-caIMR groups(P＜0.05).Compared with the L-caIMR group,the levels of IL-1β,IL-6,and TNF-α showed an increasing trend in the M-caIMR group and the H-caIMR group,and the increase was greater in the H-caIMR group than that in the M-caIMR group(P＜0.05).Multivariate anal-ysis revealed that caIMR was a factor influencing the levels of IL-1 β and IL-6(P＜0.05).Conclusion CMD may be involved in the process of myocardial remodeling in patients with acute anterior STEMI after PCI,in which inflammation plays a role.

Objective:To compare the efficacy, safety, and cost-effectiveness of the trastuzumab originator (HST) versus its biosimilar (HLX02) combined with pertuzumab and chemotherapy as neoadjuvant treatment in patients with HER-2-positive breast cancer.Methods:This retrospective cohort study included 175 patients with HER-2-positive breast cancer who received neoadjuvant therapy followed by curative surgery at the Cancer Hospital Chinese Academy of Medical Sciences between October 2020 and January 2024. Patients were divided into two groups based on the trastuzumab formulation used: the HST group ( n=89) and the HLX02 group ( n=86).The efficacy, safety, and trastuzumab-related treatment costs were compared between the two groups. Moreover, using Logistic regression model to identify the factors influencing total pathological complete response (tpCR) rates. Results:There were statistically significant differences in clinical T stage and surgical approach between the HST and HLX02 groups ( P＜0.05). Other clinicopathological characteristics, such as age and histological grade, showed no statistically significant differences ( P＞0.05), with most baseline characteristics remaining balanced between the two groups. There were no significant differences in tpCR rates ( P=0.957) or Miller-Payne (MP) grading rates ( P=0.991) between the HST and HLX02 groups. The tpCR rates for the two groups were 55.1% (49/89) and 54.7% (47/86), respectively. The rates of achieving grade 5 (G5) in the postoperative MP pathological grading system were 55.1% (49/89) and 55.8% (48/86), respectively, with no statistically significant difference ( P=0.991). Univariate and multivariate Logistic regression analyses showed that hormone receptor status is an independent risk factor affecting tpCR ( OR=0.31, 95% CI; 0.16-0.61, P＜0.001). The incidence of adverse event during neoadjuvant therapy was similar between the groups, with no occurrences of trastuzumab-related cardiac toxicity. The HLX02 regimen showed a lower cost-effectiveness ratio (586.48 vs. 604.96) and reduced trastuzumab treatment costs during neoadjuvant therapy compared to HST [tpCR:(31 208.37±2 191.00) CNY vs. (33 224.49±2 741.00) CNY; non-tpCR: 33 030.05±5 787.00) CNY vs. (33 412.50±4 203.00) CNY, P＜0.05]. Conclusions:In the neoadjuvant treatment of early-stage HER-2-positive breast cancer, HLX02 combined with pertuzumab and chemotherapy demonstrates similar efficacy and safety to the trastuzumab originator, while offering a significant cost advantage.

Objectives:To investigate the predictive value of Murray's law-based quantitative flow ratio(μQFR)in side branches for long-term clinical prognosis in patients with non-left main bifurcation lesions who underwent simple main branch stenting,and to provide a potential functional assessment standard for intervention decision-making on coronary bifurcation lesions.Methods:A retrospective analysis was conducted in 408 patients with non-left main bifurcation lesions who underwent simple main branch stenting at Lianyungang First People's Hospital and Nanjing First Hospital between July 2018 and January 2021.The study utilized third-generation QFR software to analyze pre-and post-procedure anatomical and functional parameters of the target lesion's main branch and key branches.The primary endpoint was target vessel failure(TVF)events during the 3-year follow-up.Patients were stratified into TVF and non-TVF groups.Baseline characteristics,procedural data,and pre-/post-procedural parameters of target vessels were compared between groups.Multivariable Cox regression was performed to identify predictors of TVF.Diagnostic efficacy of predictors was evaluated using area under the receiver operating characteristic(ROC)curve(AUC)with DeLong's method for comparison.Patients were dichotomized based on the optimal cutoffof post-procedural side branch μQFR,with TVF incidence rates compared via Cox regression and Kaplan-Meier analysis.Results:During 3-year follow-up,54 patients(13.2%)experienced TVF(TVF group),data were compared with 354 patients(86.76%)without TVF(non-TVF group).The TVF group showed higher post-procedural side branch diameter stenosis([32.93±17.80]%vs.[22.62±11.96]%,P<0.001)and lower μQFR(0.80±0.10 vs.0.89±0.07,P<0.001).Multivariate Cox regression identified higher post-procedural side branch μQFR as an independent protective factor against 3-year TVF(per 0.01 increase:HR=0.903,95%CI:0.850-0.959,P<0.001).ROC curves indicated that post-procedural side branch μQFR had moderate diagnostic efficacy for predicting 3-year TVF(AUC=0.769,95%CI:0.678-0.861,P<0.001),with a significantly higher AUC value than post-operative side branch area stenosis and minimal lumen diameter(both P<0.001),the optimal cutoffvalue was 0.84.Multivariate Cox regression and Kaplan-Meier survival analysis revealed markedly higher 3-year TVF rates in patients with μQFR≤0.84 compared to patients with μQFR>0.84(HR=4.007,95%CI:2.342-6.855,P<0.001;28.3%vs.7.9%,log-rank P<0.001).Conclusions:For patients with bifurcation lesions not involving the left main,the immediate post-procedural side branch μQFR could better predict 3-year TVF than anatomical indices.Maintaining post-stenting side branch μQFR>0.84 may optimize clinical outcomes when using a single-stent strategy.

Objective:To construct a humanistic care nursing program for adult ICU patients, providing guidance for the clinical practice of humanistic care in ICUs.Methods:Based on a literature review and clinical practice experience, a preliminary humanistic care nursing program for adult ICU patients was drafted. From August to September 2024, the Delphi method was used to conduct two rounds of expert consultation with 16 experts to revise the content of each item and the overall program, resulting in the final version of the humanistic care nursing program for ICU adult patients.
