Objectives:To evaluate the safety and feasibility of endovascular aortic repair without contrast agent under branch artery guidewire marking(FLARE technique).Methods:The clinical data of 7 patients who underwent contrast-free endovascular aortic repair with branch artery guidewire marking in Fuwai Hospital from 2024 to 2025 were retrospectively analyzed.The criteria for patient selection included renal insufficiency,history of contrast agent allergy,high risk of high-pressure angiography due to extensive calcification of the aortic arch,and patients'strong personal wishes,all patients merited with anatomically friendly and anchored area criteria.The patients were evaluated by preoperative computed tomography or color Doppler ultrasound,and the occlusive stent anchor point was located by branch artery guidewire marking combined with bone marking during surgery.The primary endpoints were early stage of postoperative renal function changes(comparison of preoperative and postoperative serum creatinine)and surgical technique success rate,and the secondary endpoints included the incidence of internal leakage,re-intervention rates,and incidence of aneurysm and kidney-related adverse events during follow-up.Results:Among the seven patients who underwent endovascular aortic repair without contrast using a branch artery guidewire,four were male,with an average age of(72.0±5.9)years.Six of these patients had infrarenal abdominal aortic aneurysms,two of them with bilateral renal artery severe stenosis and renal insufficiency underwent renal artery stenting combined with endovascular aortic repair,one patient had isolated chronic renal insufficiency,one had a history of iodine contrast skin allergy,and the remaining two cases wished this surgery option.The seventh patient had a penetrating ulcer in the aortic arch and descending aorta,along with extensive thrombosis and calcification in the ascending aorta,aortic arch and descending aorta.All the patients achieved surgical technique success.No iodine contrast agent was used during the procedure for endovascular aortic repair.In patients with chronic renal insufficiency and renal artery stenosis before surgery,serum creatinine levels were significantly improved after surgery.All patients did not need hemodialysis,there was no allergic reaction,and no graft-related or perioperative complications.The average follow-up was(5.8±3.0)months,all patients recovered well without re-intervention or complications.The creatinine levels did not fluctuate significantly after surgery.Conclusions:Branch artery guidewire marked contrast-free aortic endovascular repair may be a safe and feasible treatment option in selected patients,especially in patients with contraindications to contrast agents.

Objective:To observe the effect of moxibustion on angiogenesis-related indicators in knee joint synovial tissue of adjuvant arthritis model rats,and to explore the mechanism of moxibustion in inhibiting vascular endothelial growth factor(VEGF)expression in synovial tissue and further limiting the activation of Rho family proteins Rac1 and Cdc42,thereby inhibiting angiogenesis during rheumatoid arthritis(RA)treatment.Methods:Forty-eight male Sprague-Dawley rats were equally divided into a normal group,a model group,a moxibustion group,and a moxibustion+VEGF agonist group according to the random principle.The complete Freund's adjuvant method was used for modeling.On the 12th day after modeling,the moxibustion group and the moxibustion+VEGF agonist group were subjected to suspended moxibustion at bilateral Zusanli(ST36),Guanyuan(CV4),and Ashi points for 20 min each time,once a day,for a total of 15 times.The moxibustion+VEGF agonist group received VEGF agonist(tirofiban hydrochloride hydrate)injection in the knee joint cavity at the same time.Hematoxylin-eosin staining was used to evaluate the pathological changes of rat synovial tissue in each group.Immunohistochemistry was used to observe the CD31 expression level in rat synovial tissue.Western blotting was used to detect the levels of VEGF,Rac1,and Cdc42 protein in rat synovial tissue,and polymerase chain reaction(PCR)was used to detect the VEGF mRNA expression.Results:Compared to the normal group,the expression levels of CD31 protein and VEGF mRNA and protein in rat synovial tissue in the model group increased significantly(P<0.01),and the expression levels of phospho-Rac1 and phospho-Cdc42 proteins also increased significantly(P<0.01).After moxibustion intervention,the expression levels of CD31 protein and VEGF mRNA and protein in the moxibustion group were significantly lower than those in the model group(P<0.01),while the differences in each indicator between the moxibustion+VEGF agonist group and the model group were not statistically significant(P>0.05).Compared to the moxibustion group,the expression levels of CD31 protein,VEGF mRNA and protein,phospho-Cdc42,and phospho-Rac1 in the moxibustion+VEGF agonist group increased significantly(P<0.01).Conclusion:Moxibustion improved synovial inflammation in RA by inhibiting angiogenesis.The mechanism may be to regulate angiogenesis-related VEGF,restrict the activation of Rac1 and Cdc42,and inhibit pseudopodia formation in vascular endothelial cells,thereby reducing angiogenesis.

Objective To investigate the relationship between ST-segment elevation myocardial infarction(STEMI)treatment time nodes and coronary microcirculation dysfunction(CMD)after primary percutaneous coronary intervention(PCI)and its prognosis,providing evidence for early identification of high-risk patients,further optimization of treatment system,shortening treatment time and improving prognosis.Methods This study selected 150 STEMI patients who received primary PCI at the 920th Hospital of the Joint Logistic Support Force of the People's Liberation Army of China from March 2023 to September 2023 as the CMD group after PCI(89 cases),with a microcirculation resistance index(caIMR)of≥40 U based on coronary angiography.caIMR＜40 U was classified as the non-CMD group(61 cases).The clinical data,various examination indicators and imaging data of the two groups of patients were collected,and the occurrence of major adverse cardiovascular events(MACE)within half a year after direct PCI of the patients was followed up.The correlation between the two variables was analyzed using Spearman.Multivariate Logistic regression was used to analyze the relationship between each treatment time point and the occurrence of CMD after direct PCI.Using receiver operating characteristic(ROC)curve analysis to predict the occurrence of CMD after direct PCI.The survival curves between the two groups were plotted using the Kaplan-Meier method.Results The levels of symptom onset-to-balloon(S-to-B),symptom onset-to-first medical contact(S-to-FMC),first medical contact-to-balloon(FMC-to-B),symptom onset-to-door(S-to-D)and first medical contact-to-door(FMC-to-D)in the CMD group were significantly higher than those in the non-CMD group(all P＜0.05).Correlation analysis showed that S-to-D,S-to-FMC,the time from FMC-to-B,and the time from FMC-to-D were all positively correlated with the time from S-to-B(r=0.996,P＜0.001;r=0.937,P＜0.001;r=0.431,P＜0.001;r=0.441,P＜0.001).Multivariate Logistic regression analysis indicated that the duration of S-to-D(OR 2.165,95％CI 1.655-2.830,P＜0.001)was a significant influencing factor for CMD.Moreover,S-to-D has a relatively high predictive value for the occurrence of CMD after direct PCI.The area under the ROC curve is 0.898(95％CI 0.850-0.946,P＜0.001),the optimal cut-off value is 231 min,the sensitivity is 82.0％,and the specificity is 88.5％.Kaplan-Meier curve analysis showed that the cumulative survival rate of MACE outcomes in the CMD group was significantly lower than that in the non-CMD group(Log-rank P=0.009).Conclusions Shortening the S-to-D time can reduce the occurrence of CMD after PCI,thereby reducing the incidence of MACE and improving prognosis.

Objective:To compare the clinical efficacy of O-arm navigation-assisted percutaneous vertebroplasty (PVP) versus C-arm-guided PVP in the treatment of postoperative recurrent vertebral fractures following Kümmell′s disease.Methods:A retrospective cohort study was conducted to analyze the clinical data of 48 patients with postoperative recurrent vertebral fractures following Kümmell′s disease who were admitted to Zhengzhou Orthopedic Hospital from January 2021 to September 2024, including 16 males and 32 females, aged 51-85 years [(69.8±6.6)years]. Among them, 21 patients had stage I Kümmell′s disease and 27 stage II. Fractured vertebrae involved T 8-T 10 in 4 patients, T 11-L 2 in 29, and L 3-L 5 in 15. Twenty-five patients underwent O-arm navigation-assisted PVP (O-arm-assisted group) and 23 underwent C-arm-guided PVP (C-arm-guided group). The two groups were compared in terms of the operative time, intraoperative blood loss, bone cement volume, and bone cement filling saturation rate in the injured vertebral body. The visual analogue scale (VAS) scores and Oswestry disability index (ODI) values were also compared before operation, at 1 day, 1 month, 6 months after operation, and at the last follow-up. The excellent-good rate based on the MacNab criteria at the last follow-up and incidence of postoperative complications were detected. Results:All the patients were followed up for 6-24 months [(13.3±3.5)months]. There were no significant differences in the operative time, operative blood loss or bone cement volume between the two groups ( P>0.05). The O-arm-assisted group demonstrated a bone cement filling saturation rate of 96% (24/25) in the fractured vertebrae, significantly higher than 65% (15/23) in the C-arm-guided group ( P<0.05). The VAS scores before operation, at 1 day, and 1 month after operation were (8.4±1.0)points, (1.9±0.7)points, and (1.8±0.6)points, respectively in the O-arm-assisted group, while they were (8.3±0.8)points, (2.0±0.6)points, and (1.9±0.5)points, respectively in the C-arm-guided group ( P>0.05). The ODI values before operation, at 1 day, and 1 month after operation were 76.6±8.2, 20.4±4.5, and 19.8±4.1, respectively in the O-arm-assisted group, and 74.9±9.1, 21.3±3.6, and 20.9±3.2, respectively in the O-arm-assisted group ( P>0.05). At 6 months after operation and at the last follow-up, the VAS scores were (1.4±0.5)points and (1.5±0.5)points in the O-arm-assisted group, with significant improvement compared to (1.8±0.4)points and (1.9±0.3)points in the C-arm-guided group ( P<0.01); the ODI values were 17.8±3.2 and 18.2±3.5 in the O-arm-assisted group, with significant improvement compared to 19.9±3.1 and 21.3±4.0 in the C-arm-guided group ( P<0.05). Both groups demonstrated significant improvements in VAS scores and ODI values at 1 day, 1 month, 6 months after operation, and at the last follow-up, compared to those preoperatively ( P<0.05), while no statistically significant differences were found in VAS scores or ODI values at any postoperative timepoints ( P>0.05). According to the MacNab criteria, the O-arm-assisted group had a 100% (25/25) excellent-good rate, compared to 74% (17/23) in the C-arm-guided group ( P<0.05). The complication rate was 4% (1/25) in the O-arm-assisted group, significantly lower than 35% (8/23) in the C-arm-guided group ( P<0.05). Conclusion:O-arm navigation-assisted PVP for postoperative recurrent vertebral fractures following Kümmell′s disease offers advantages in precise cement delivery with sufficient dispersion, enhanced pain relief, functional recovery, improved quality of life, and reduced complication rates when compared to C-arm navigation-assisted PVP.

Asarum forbesii is a perennial herb born in a shaded and humid environment, which is warm in nature. With the efficacy of warming lung, resolving fluid retention, and relieving coughs, it can be used to treat the syndrome of cold fluid accumulating in lung. To investigate the effects of different shading conditions on the composition and efficacy of A. forbesii, this study planted A. forbesii under 20% natural light(NL20), 40% natural light(NL40), 60% natural light(NL60), and 80% natural light(NL80) and utilized ultra performance liquid chromatography(UPLC) and micro broth 2-fold dilution method to detect the volatile chemical compounds and the minimum inhibitory concentration. At the same time, the study investigated the effects of A. forbesii grown under different shading conditions on the signs, pathological changes of lung tissues, serum cytokine levels, activities of mitochondrial respiratory chain complexes Ⅰ-Ⅴ in lung tissues, and relative expression of related genes of mice with syndrome of cold fluid accumulating in lung. The results indicated that with the increase of shading, the content of kakuol, methyl eugenol, and asarinin in A. forbesii and the antibacterial effect showed a tendency of increasing first and then decreasing, and the NL40 group was significantly better than the other groups. Under the conditions of NL20 and NL40, A. forbesii significantly alleviated the pathological damage to lung tissues, restored the homeostasis of the lung, and enhanced the energy metabolism level of mice with syndrome of cold fluid accumulating in lung. In addition, A. forbesii planted under the two conditions reduced the content of interleukin-8(IL-8), interleukin-13(IL-13), tumor necrosis factor-α(TNF-α), and mucin 5AC(MUC5AC), increased the levels of interleukin-10(IL-10) and aquaporin 1(AQP1), lowered the expression of MMP9, VEGF, TGF-β, and MAPK3. In conclusion, the therapeutic effect of A. forbesii on the syndrome of cold fluid accumulating in lung was positively correlated with the degree of shading, and the chemical composition and efficacy of warming lung and resolving fluid retention were optimal under the conditions of NL20-NL40. This study can provide reference for the pharmacological research and cultivation of A. forbesii.
