Standardizing the emergency assessment and management process for patients with implantable continuous-flow left ventricular assist device (LVAD) in emergency and intensive care settings is of great significance for reducing delays in diagnosis and treatment, lowering the mortality associated with LVAD-related emergencies, and improving overall prognosis and long-term survival. To this end, a multidisciplinary expert committee was convened to develop this consensus, integrating international evidence-based findings with clinical practice experience in China, with an emphasis on highlighting the characteristics of domestically manufactured devices. The aim is to establish an actionable standardized emergency management protocol to enhance clinical identification and response efficiency, reduce the risk of LVAD-related emergencies, and improve patient outcomes. Using a modified Delphi method, this consensus proposes a structured decision-making pathway that integrates an "ABC" rapid assessment with parallel device troubleshooting, prioritizing the use of point-of-care echocardiography for hemodynamic evaluation and complication assessment. Key emergency scenarios covered include low-flow alarms, pump thrombosis, right heart dysfunction, bleeding and anticoagulation imbalance, arrhythmias, and cardiac arrest. This consensus applies to implantable continuous-flow LVADs commonly used in China, including domestically manufactured devices such as Corheart 6, CH-VAD, EVAHEART, and HeartCon, as well as the imported device HeartMate 3.

This study aimed to systematically construct a transitional curriculum for newly recruited surgical residents and to evaluate its preliminary application outcomes through pre and postimplementation assessments, so as to provide practical references for the design and dissemination of such curricula. A singlecenter historical controlled design was adopted. Residents admitted in 2020 served as the traditional teaching group (preimplementation), while those admitted in 2024 served as the teaching reform group (postimplementation). Both groups completed selfadministered surveys three months after admission. Following Kern's sixstep approach, the transitional curriculum for surgical residents was developed based on needs assessment results, comprising 18 theoretical lectures and 3 practical skill training sessions, all delivered within the first three months after admission. Selfadministered questionnaires were used to assess clinical readiness and teaching satisfaction in both groups at three months postadmission. Betweengroup comparisons were performed using independent samples ttests, with Cohen's d effect sizes calculated, along with sensitivity analyses and power analyses. The teaching reform group ( The transitional curriculum developed in this study provides a systematized framework of theoretical instruction and foundational skills training for newly admitted surgical residents, and its feasibility has been preliminarily validated. Its effectiveness, however, warrants further confirmation through largersample, prospective studies with objective outcome measures.

ObjectiveTo explore the potential mechanism by which Huoxue Wentong prescription (HXWT) ameliorates post-myocardial infarction (MI) ventricular remodeling by regulating endothelial-to-mesenchymal transition (EndMT) via the hypoxia-inducible factor-1α (HIF-1α)/transforming growth factor-β1 (TGF-β1)/periostin (POSTN) signaling pathway. MethodsEighty SPF-grade male Sprague-Dawley rats were randomly assigned to a sham-operated group (n=10) and a modeling group (n=70). The MI model was established by left anterior descending coronary artery ligation. Successfully modeled rats were further randomized into a model group, a sacubitril/valsartan (Entresto, 0.021 g·kg-1) group, and low, medium, and high-dose (4.15, 8.30, and 16.60 g·kg-1, respectively) HXWTF groups (n=10 per group). From postoperative day 2, rats received HXWTF or sacubitril/valsartan by gavage once daily for 4 weeks, and those in sham and model groups received an equal volume of normal saline. After intervention, general conditions were assessed. Echocardiography was performed to measure the left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), left ventricular end diastolic diameter (LVEDD), and left ventricular end systolic diameter (LVESD). Hematoxylin and eosin (HE) staining was employed to evaluate myocardial histopathology, and Masson's trichrome staining to assess myocardial fibrosis. Serum levels of B-type natriuretic peptide (BNP), interleukin (IL)-6, IL-10, and matrix metalloproteinase-9 (MMP-9) were determined by enzyme-linked immunosorbent assay (ELISA). Collagen type Ⅰ (ColⅠ) expression was assessed by immunohistochemistry. Immunofluorescence double staining was adopted to detect the expression of platelet endothelial cell adhesion molecule-1 (CD31) and α-smooth muscle actin (α-SMA). Western blot was performed to quantify the expression of collagen type Ⅰ α2 (Col1A2), VE-cadherin, CD31, α-SMA, HIF-1α, TGF-β1, and POSTN. ResultsCompared with the sham group, the model group exhibited thinning and collapse of the left ventricular wall, decreased LVEF and LVFS and increased LVEDD and LVESD (P<0.01), disrupted myocardial fibers with marked inflammatory cell infiltration, increased collagen deposition, enhanced ColⅠ immunoreactivity, elevate serum BNP, IL-6, and MMP-9 levels, a reduced IL-10 level (P<0.01), downregulated expression of CD31 and VE-cadherin, and upregulated expression of α-SMA, Col1A2, HIF-1α, TGF-β1, and POSTN (P<0.05,P<0.01), accompanied by increased CD31/α-SMA co-localization. Compared with the model group, the sacubitril/valsartan group and all HXWTF groups showed improved ventricular wall structure, increased LVEF and LVFS, decreased LVEDD and LVESD, attenuated myocardial injury with reduced inflammatory infiltration and collagen deposition, declined serum BNP, IL-6, and MMP-9 levels, an elevated serum IL-10 level, upregulated expression of CD31 and VE-cadherin, downregulated expression of α-SMA, Col1A2, HIF-1α, TGF-β1, and POSTN, and reduced CD31/α-SMA co-localization (P<0.05,P<0.01). No significant differences were observed between the sacubitril/valsartan group and the medium- and high-dose HXWTF groups. ConclusionHXWTF may regulate the HIF-1α/TGF-β1/POSTN pathway to inhibit EndMT, thereby ameliorating post-MI ventricular remodeling.

Objective To explore the valve regurgitation status of left heart after the implantation of left ventricular assist device (LVAD) and its effect on prognosis of patients with LVAD implantation. Methods A total of 35 patients with cardiomyopathy who underwent magnetic levitation LVAD implantation at Zhongshan Hospital, Fudan University from February 2021 to July 2024 were retrospectively selected. Clinical data during hospitalization were collected, including preoperative basic data and postoperative valve regurgitation status. Telephone follow-ups were conducted to monitor patients’ survival status and transthoracic echocardiography was used to assess left valve function. Kaplan-Meier survival curves and log-rank test were employed to compare the survival rate of patients with different levels of valve regurgitation. Results The 35 patients had a mean age of (53.9±11.1) years, with 85.7% male, and 3 patients (8.6%) died during hospitalization. Preoperatively, 17 patients (48.6%) had moderate or greater mitral regurgitation, while all 35 patients had less than moderate aortic regurgitation. One month postoperatively, thirty patients were followed up, among which 24 patients (80%) had less than moderate mitral regurgitation, including 11 cases with alleviated regurgitation compared to pre-surgery; 6 patients (20%) had moderate or greater mitral regurgitation, including 4 cases with stable regurgitation and 2 cases with progression of regurgitation compared to pre-surgery; 2 patients (6.7%) had progression of aortic regurgitation to moderate or greater. The follow-up time was 1.2 (1.0, 2.1) years, with 1-year survival rate of 91.4% and 3-year survival rate of 71.1%. Survival analysis showed that the 3-year survival rate of patients with moderate or greater mitral regurgitation one month postoperatively was significantly lower than that of patients with less than moderate regurgitation (66.7% vs 83.3%, P=0.046). Conclusions After the implantation of magnetic levitation LVAD, most patients showed improvement in mitral regurgitation, while aortic regurgitation remained unchanged. The degree of mitral regurgitation one month postoperatively is associated with prognosis.

According to the "Regulations on clinical application management of medical technologies", physicians intending to carry out restricted technologies must undergo standardized training and pass assessments in accordance with the clinical application management standards for the respective technology. As ventricular assist technology is classified as a nationally restricted technology, standardized training is one of the essential conditions for its application. This paper primarily explores the standardized training for the clinical application of ventricular assist technology in Shanghai, in light of its background, clinical application, and current training status. It proposes the training requirements for ventricular assist technology, animal training assessment standards, and clinical practice assessment standards in Shanghai, aiming to promote the standardized development and high-quality advancement of ventricular assist technology in Shanghai.

The study explores the traditional Chinese medicine (TCM) diagnostic and treatment approach to coronary microvascular disease (CMVD) from the perspective of "disharmony of blood collaterals and dysfunction of qi transformation". It is proposed that the core pathogenesis of CMVD lies in these two mechanisms. From an integrative medicine perspective, different CMVD types are analyzed based on their specific pathogenesis. Through clinical practice, four targeted treatment methods, i.e. warming, unblocking, tonifying, and activating, are formulated. CMVD caused by atherosclerosis is primarily associated with myocardial ischemia, myocardial infarction, and coronary revascularization, with corresponding pathological mechanisms of latent pathogenic obstruction, toxic accumulation in the collaterals, and deficiency with collateral stasis. The disease progression exhibits characteristics of correlation, staging, and transformation. Accordingly, treatment principles include warming to assist qi transformation, unblocking obstruction and dispelling turbidity, activating to disperse toxic stasis and invigorate collaterals, and tonifying to eliminate stasis and nourish collaterals. For CMVD unrelated to atherosclerosis, attention should be paid to the underlying disease, analyzing the main syndromes of blood and collateral disharmony. An approach combining disease-syndrome differentiation with blood and collateral regulation is emphasized for precise treatment.

Objective:To compare the impact of preoperative pulmonary vascular resistance(PVR) levels on the prognosis of patients undergoing left ventricular assist device(LVAD)implantation.Methods:A retrospective analysis was conducted on the clinical data of 33 patients among September 2021 and June 2024, who underwent LVAD implantation at Zhongshan Hospital, Fudan University. 29 males and 4 females, with a mean age of(53.61±9.65)years old. The cohort included 30 cases of dilated cardiomyopathy, 2 cases of ischemic cardiomyopathy, and 1 case of noncompaction cardiomyopathy. Patients were grouped based on a preoperative PVR threshold of 3 WU, Preoperative data from Swan-Ganz catheterization, liver and renal function indicators, as well as other relevant clinical parameters were recorded. Patients were followed up to assess differences in survival outcomes.Results:Preoperative PVR was elevated in 18 cases(60%)of the patients, with a mean preoperative PVR of(3.16±1.71)WU. Immediate postoperative right heart catheterization was performed in 20 patients, showing a significant reduction in PVR from(3.85±1.72)WU preoperatively to(1.80±1.38)WU postoperatively( P<0.05). The cardiac index improved significantly from(1.95±0.63)L·min -1·m -2 preoperatively to(4.25±1.26)L·min -1·m -2 postoperatively( P<0.001). The mean follow-up duration was(14.78±12.06)months, no significant difference in postoperative survival was observed between the two groups(100% vs. 80%, P=0.667). Conclusion:Increased pulmonary resistance is often secondary to left heart dysfunction. After the implantation of a LVAD, pulmonary resistance can be improved. For patients with relatively normal right heart function before surgery, elevated pulmonary resistance does not affect the short-term outcomes of the implantation.

The pathogenesis and progression of depression are closely associated with functional dysregula-tion in the brain's reward and emotion-modulating circuits.As the central hub of the reward system,the nucleus accumbens(NAc)forms aberrant neural circuits with multiple brain regions-including the ventral tegmental area(VTA),medial prefrontal cortex(mPFC),amygdala(AMY),hippocampus(HIP),and paraventricular nucleus of the thalamus(PVT)-which have been empirically linked to depressive symptomatology.Acupuncture,with its multi-target therapeutic profile,aligns well with the multifactorial and multisystem dysregulation characteristic of depressive disorders.This review systematically examines the functional alterations of the NAc-centered neural circuitry in depression and explores the potential mechanisms of acupuncture intervention.Evidence suggests that acupuncture holistically ameliorates depression by:modulating dopaminergic transmission in the VTA-NAc pathway,enhancing neurotransmitter equilibrium in the mPFC-NAc circuit,bidirectionally regulating emotional stability via the AMY-NAc loop,attenuating HIP-NAc glutamatergic hyperactivity,and optimizing excitatory signaling in the thalamus-NAc circuit.Furthermore,this synthesis emphasizes a systems-level integration of circuit mechanisms,highlighting both the clinical applicability of acupuncture in depression treatment and recent advances in mechanistic research.The findings provide robust theoretical foundations and practical guidance for clinical practice,bridging translational neuroscience with therapeutic innovation.

Robot-assisted surgery with its advantages such as three-dimensional high-definition vision, dexterous robotic arms, and tremor filtration, is increasingly being applied to complex radical gastrectomy. However, the role of the surgical assistant remains crucial during the procedure. The assistant is responsible for tasks outside the console, including adjusting robotic arms, changing instruments, exposing the surgical field, and addressing unexpected situations. The technical proficiency of the assistant and their collaboration efficiency with the primary surgeon directly impact the smoothness of surgery and patients' outcomes. With the expansion of robot-assisted surgical indications, the establishment of a standardized training system and the optimization of team collaboration models have become urgent challenges to address. This article draws on the author's practical experience as an assistant in robot-assisted gastric cancer surgeries, conducting an in-depth analysis of the responsibilities and operational skills of surgical assistants in robot-assisted procedures. The aim is to develop a relatively comprehensive set of operational guidelines for surgical assistants in robot-assisted radical gastrectomy, providing valuable references for enhancing the overall efficiency of surgical teams and improving surgical outcomes.
