Objective:Utilizing the principles of mechanical vibrations dissections and low-temperature coagulation of harmonic scalpel, and combining the magnifying effect of 3D thoracoscopy and the advantage of low trauma, we used harmonic scalpel to harvest the left internal mammary artery (LIMA) under thoracoscopy, and explored the feasibility and early effect of harmonic scalpel in minimally invasive coronary artery bypass grafting (MICABG).Methods:A total of 488 patients who underwent MICABG from July 2021 to December 2023 in Dong E Hospital were collected. Among them, 347 patients was harvested using harmonic scalpel under thoracoscopy. Following anastomosis, the blood flow and pulsatility index (PI) from the graft to the target vessel were determined using a transit time flow meter (MiraQ, Medistim, Norway), and patency was checked. Data from 347 patients were analyzed.Results:All 347 patients were performed under non-extracorporeal circulation and successful graft patency was achieved in all patients. Analysis of 79 patients revealed a median time to LIMA acquisition of 32 min and a median length of acquisition of 15 cm. No graft-related events or complications occurred in any of the patients, and 2 patients died postoperatively. During a median follow-up of 12.1 months, only one patient experienced graft occlusion necessitating intervention.Conclusion:The utilization of harmonic scalpel for LIMA harvesting in MICABG is feasible and yields stable early results.

Objective:To construct an ultrasound-responsive nano-oxygen carrier,and to enhance cell survival within myocardial patches and promote myocardial infarction(MI)repair.Methods:Ultrasound-responsive phase-change nanobubbles(ND)were first prepared and integrated into GelMA hydrogel to construct myocardial patches. Low-intensity pulsed ultrasound(LIPUS)irradiation was applied to explore whether the nanobubbles could optimize the hydrogel properties. Hemoglobin(Hb)was further encapsulated into the nanobubbles to construct an oxygen carrier(ND-Hb). In vitro and in vivo experiments were conducted to evaluate whether the optimized myocardial patches could improve cell survival and facilitate MI repair. In vitro,cell-loaded patches were divided into 6 groups(control,ND,Hb,LIPUS,LIPUS+ND,and LIPUS+oxygen carrier groups)to assess the cell viability and protein expression. In vivo,an acute MI model was established in SD rats,which were randomly assigned to 4 groups(control,Hb,LIPUS+ND,and LIPUS+oxygen carrier groups).Myocardial patches were implanted,and cardiac function(echocardiography),cell survival(BLI imaging),angiogenesis(CD31 and α-SMA immunofluorescence)and connexin protein expression(Cx43)were evaluated. Results:Following the incorporation of ND and LIPUS irradiation,scanning electron microscopy revealed numerous micropores(about 2 μm)within the hydrogel were observed by scanning electron microscopy. The nano-oxygen carrier was successfully constructed,with a particle size of(301.2 ± 92.4)nm,and released oxygen under LIPUS stimulation. In vitro,at days 3,7,and 14,the cell survival rates in the LIPUS+oxygen carrier group[(89.6 ± 2.1)%,(79.3 ± 1.8)%,(70.9 ± Conclusions:This study successfully employs LIPUS combined with ND-Hb to enhance hydrogel properties,facilitating nutrient exchange within myocardial patches. Additionally,ultrasound-mediated oxygen release improves seed cell survival and promotes myocardial infarction repair.

OBJECTIVE To analyze the impact of intergenerational substitution effect of the drugs with the same indication on fund expenditures for national medical insurance for this indication in China, taking national medical insurance negotiated drugs for non-small cell lung cancer (hereinafter referred to as “NSCLC national negotiation drugs”) as an example. METHODS The sales amounts of 15 types of NSCLC national negotiated drugs in secondary and tertiary public hospitals across seven sample provinces from 2017 to 2023 were collected from the Pharmaceutical Drug Database of the China National Pharmaceutical Industry Information Center. A sliding t-test and Mann-Kendall trend test were used to evaluate the trends in sales amounts and DDDs. Taking epidermal growth factor receptor(EGFR)-tyrosine kinase inhibitors (TKIs) and anaplastic lymphoma kinase (ALK)-TKIs as examples, the generational substitution characteristics of these drugs were analyzed. RESULTS The change points of sales amounts and DDDs differed slightly across provinces; the change points of sales amount were mostly concentrated between the first quarter of 2019 and the second quarter of 2020, while those for DDDs were primarily concentrated in the first to second quarters of 2021. In five provinces, i.e. Beijing, Heilongjiang, Jiangsu, Sichuan and Shaanxi, sales amounts showed no significant upward trend after the breakpoints (P>0.05), whereas in Guangdong and Hubei, both sales amounts and DDDs continued to rise significantly following the breakpoints (P<0.05). Since 2020, the growth in sales amounts of EGFR-TKIs had slowed. After 2021, the sales amounts and DDDs of first- and second-generation EGFR-TKIs declined, while third-generation EGFR-TKIs showed clear substitution effects. The sales amounts of ALK-TKIs continuedto grow. However, the sales amounts and DDDs of first-generation ALK-TKIs had declined year by year, with second-generation ALK-TKIs demonstrating a significant substitution effect on first-generation ones, while third-generation ALK-TKIs had not yet shown a clear substitution trend. CONCLUSIONS With the annual access to and renewal of drugs in national medical insurance negotiations, the overall expenditure trend for NSCLC negotiated drugs comes to a plateau. The intergenerational substitution relationships of drugs with the same indication achieve a relative balance in fund expenditures for negotiated drugs with the same indication. It is recommended that pharmaceutical companies carefully consider their research pipelines, and that medical insurance authorities, during the renewal management process, pay attention to the impact of drug substitution effects on the overall actual expenditure of medical insurance funds for that specific target or the same indication, and scientifically evaluate the extent of price reductions during contract renewals.

Vein graft(VG)failure(VGF)is associated with VG intimal hyperplasia,which is characterized by abnormal accumulation of vascular smooth muscle cells(VSMCs),Most neointimal VSMCs are derived from pre-existing VSMCs via a process of VSMC phenotypic transition,also known as dedifferentiation.There is increasing evidence to suggest that ginger or its bioactive ingredients may block VSMC dedif-ferentiation,exerting vasoprotective functions;however,the precise mechanisms have not been fully characterized.Therefore,we investigated the effect of ginger on VSMC phenotypic transition in VG remodeling after transplantation.Ginger significantly inhibited neointimal hyperplasia and promoted lumen(L)opening in a 3-month VG,which was primarily achieved by reducing ferroptotic stress.Fer-roptotic stress is a pro-ferroptotic state.Contractile VSMCs did not die but instead gained a proliferative capacity and switched to the secretory type,forming neointima(NI)after vein transplantation.Ginger and its two main vasoprotective ingredients(6-gingerol and 6-shogaol)inhibit VSMC dedifferentiation by reducing ferroptotic stress.Network pharmacology analysis revealed that 6-gingerol inhibits fer-roptotic stress by targeting P53,while 6-shogaol inhibits ferroptotic stress by targeting 5-lipoxygenase(Alox5),both promoting ferroptosis.Furthermore,both ingredients co-target peroxisome proliferator-activated receptor gamma(PPARγ),decreasing PPARγ-mediated nicotinamide adenine dinucleotide phosphate(NADPH)oxidase 1(Nox1)expression.Nox1 promotes intracellular reactive oxygen species(ROS)production and directly induces VSMC dedifferentiation.In addition,Nox1 is a ferroptosis-promoting gene that encourages ferroptotic stress production,indirectly leading to VSMC dedifferenti-ation.Ginger,a natural multi-targeted ferroptotic stress inhibitor,finely and effectively prevents VSMC phenotypic transition and protects against venous injury remodeling.

Vein graft (VG) failure (VGF) is associated with VG intimal hyperplasia, which is characterized by abnormal accumulation of vascular smooth muscle cells (VSMCs). Most neointimal VSMCs are derived from pre-existing VSMCs via a process of VSMC phenotypic transition, also known as dedifferentiation. There is increasing evidence to suggest that ginger or its bioactive ingredients may block VSMC dedifferentiation, exerting vasoprotective functions; however, the precise mechanisms have not been fully characterized. Therefore, we investigated the effect of ginger on VSMC phenotypic transition in VG remodeling after transplantation. Ginger significantly inhibited neointimal hyperplasia and promoted lumen (L) opening in a 3-month VG, which was primarily achieved by reducing ferroptotic stress. Ferroptotic stress is a pro-ferroptotic state. Contractile VSMCs did not die but instead gained a proliferative capacity and switched to the secretory type, forming neointima (NI) after vein transplantation. Ginger and its two main vasoprotective ingredients (6-gingerol and 6-shogaol) inhibit VSMC dedifferentiation by reducing ferroptotic stress. Network pharmacology analysis revealed that 6-gingerol inhibits ferroptotic stress by targeting P53, while 6-shogaol inhibits ferroptotic stress by targeting 5-lipoxygenase (Alox5), both promoting ferroptosis. Furthermore, both ingredients co-target peroxisome proliferator-activated receptor gamma (PPARγ), decreasing PPARγ-mediated nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 1 (Nox1) expression. Nox1 promotes intracellular reactive oxygen species (ROS) production and directly induces VSMC dedifferentiation. In addition, Nox1 is a ferroptosis-promoting gene that encourages ferroptotic stress production, indirectly leading to VSMC dedifferentiation. Ginger, a natural multi-targeted ferroptotic stress inhibitor, finely and effectively prevents VSMC phenotypic transition and protects against venous injury remodeling.
