RESUMEN
[Abstract] Objective To establish an inflammation model by stimulating BV2 microglia by lipopolysaccharide, and to explore the regulation effect of ginsenoside Rg1 on inflammation by activating peroxisome proliferator activated receptor γ(PPARγ) receptor protein. Methods BV2 microglia were randomly divided into control group, model group, ginsenoside Rg1 group, rosiglitazone group and GW9662 group. The control group did not do any treatment, the model group was treated with 1 mg/ L lipopolysaccharide, and the other groups were treated with lipopolysaccharide added with 0. 4 mmol/ L ginsenoside Rg1, 10 μmol/ L rosiglitazone or 10 μmol/ L respectively. GW9662. The proliferation of BV2 microglia in each group was detected by CCK-8 method; PPAR-γ, phospho-NF-κB p65 (p-NF-κB p65), induced expression of inducible nitric oxide synthase(iNOS) and human arginase 1(ARG-1) proteins. ELISA was used to detect the inflammatory factors interleukin-1β(IL-1β), interleukin-6(IL-6), interleukin-8(IL-8) and the content of tumor necrosis factor-α (TNF-α). Results Compared with the control group, the cell proliferation rate in the model group was significantly increased, and the contents of IL-1β, IL-6, IL-8 and TNF-α increased significantly. The result of immunofluorescence and Western blotting showed that iNOS and p-NF-κB p65 increased significantly, and the positive expressions of PPARγ and ARG-1 decreased significantly(both P<0. 01). The expression level of TNF-α decreased, the positive expressions of iNOS and p-NF-κB p65 decreased significantly, and the positive expressions of PPARγ and ARG-1 increased significantly(all P<0. 01). Conclusion Ginsenoside Rg1 inhibits the inflammatory response of BV2 microglia after lipopolysaccharide stimulation, and its mechanism may be related to the regulation of PPARγ/ NF-κB pathway to promote the M2-type polarization of microglia.

RESUMEN
@#Objective To investigate the efficacy of subclavian-carotid transposition (SCT) in treating patients with proximal subclavian artery occlusive diseases who were unable to be intervened, such as failure of intervention, congenital malformation and unwillingness to intervention. Methods A retrospective review of 19 patients with proximal subclavian artery occlusion who underwent SCT from May 2016 to December 2018 was done. There were 14 males and 5 females with an average age of 54.05±17.34 years. The advantages and disadvantages of SCT in the treatment of proximal subclavian artery occlusion were analyzed. Results All patients achieved immediate remission of symptoms after surgery. The stenosis degree of the proximal subclavian artery decreased from 100.0%±0.0% to 12.7%±10.1% after surgery. The average blood pressure difference between the unaffected side and the affected side decreased from 11.95±10.60 mm Hg to 0.89±5.75 mm Hg (P<0.01). Peripheral nerve injury occurred in 7 (36.8%) patients. The in-patient cost of subclavian artery occlusion patients who received subclavian artery interventional therapy in our hospital during the corresponding period was 3 392.12 yuan higher than that of the SCT group in average (if eliminating the patients whose cost was far from the average value, the cost of interventional therapy was 4 812.01 yuan higher than that of the SCT group in average). During 1-3 years' follow-up, 6 patients with neurological complication relieved. One- and three-year patency rates were 100.0%. No perioperative stroke, death or re-operation happened. Conclusion SCT is an ideal process for the patients with subclavian artery occlusion who cannot accept subclavian artery interventional therapy.
RESUMEN
@#Aortic arch disease is one of the research hotspots and treatment difficulties in the field of aorta, including aortic arch aneurysms, pseudoaneurysm, ulcer, dissection and intramural hematoma. By summarizing the clinical data of the vascular surgery center of Fuwai Hospital of Chinese Academy of Medical Sciences in the past five years and combining with the latest theories of the cutting-edge development of aortic surgery, the authors proposed the "HENDO" concept, including using hybrid technique (H), endovascular repair (Endo) and open surgery (O), properly to treat aortic arch pathologies individually. The authors advocated the establishment of HENDO team and cooperation mechanism in large aortic centers, to eliminate technical shortcomings of a single surgeon by fully mastering the three main technology clusters by teamwork. Accordingly, the best treatment for each patient can be administrated and the survival rate and quality of life can be improved eventually.

RESUMEN
In order to require ideal proximal landing zone and durable long-term outcome, it is necessary to reconstruct the left subclavian artery(LSA) blood supply as much as possible in thoracic aortic endovascular repair(TEVAR). With the advent and progress of diverse assisted techniques and devices, several procedures for the reconstruction of the left subclavian artery have been developed and widely utilized, including surgical LSA bypass or transposition, chimney technique, periscope technique, fenestration and branched stent-graft, which have expanded the proximal landing zone and widened the indication for original TEVAR. This article describes the advantages and pitfalls of each revascularization methods. Anatomies of aortic arch and LSA, urgency and types of pathologies, proficiency of the surgeon with different revascularization techniques and pre-operative risk score of patient should be evaluated in procedure selection. In clinical application, patient-specific evaluations and individualized considerations are essential for initialize the therapeutic strategy and decision making.
