Clinical and prognostic features in asymptomatic and symptomatic patients with arteriosclerosis obliterans

Background: Patients with arteriosclerosis obliterans (ASO) often have co-existing atherosclerotic diseases. The purpose of this study was to examine the clinical features of patients with ASO, including the overlap of atherosclerotic risk factors, characteristics of car-diovascular events, and clinical prognosis. Method: We enrolled 205 consecutive patients who had ankle brachial index (ABI) of ?0.9 between January 2008 and December 2009. Fontaine (F) classification and clinical background were evaluated and clinical events including mortality and major adverse cardiocerebro-vascular events (MACCEs) were determined. Results: There was a high prevalence of each risk factor. Sixty- five percent of subjects had three or more of the four overlapping risk factors, including hypertension, dia- betes, dyslipidemia, and smoking. After a maximum follow-up of 800 days, the incidence of MACCEs and mortality was 46% and 10%, respectively. We divided the patients into two groups according to the presence of ASO symptoms (F1 and F2-4) and compared the incidence of events. The incidence of MACCEs and mortality in the F2-4 group was significantly higher than that in the F1 group (P = 0.048, P = 0.044, respectively). After excluding lower extremity revascularization, coronary artery disease was a common cause of MACCEs, and the mortality rates after MACCEs increased in a stepwise manner according to F classification severity (P = 0.028). Conclusion: Patients with ASO had overlapping coronary risk factors and a high incidence rate of cardiovascular events. The incidence of coronary events was common, especially in symptomatic patients, and the mortality rates after MACCEs were high in accordance with F classification severity.

Association of the plasminogen activator inhibitor-1(PAI-1) gene 4G/5G promoter polymorphism in Buerger's disease (Tromboangiitis obliterans)

Thromboangiitis obliterans (TAO) is an unusual tobacco-associated vasculopathy that is a non- atherosclerotic inflammatory disorder of unkn- own etiology that affects small and medium- sized vessels of the extremities. The single guanosine nucleotide deletion/insertion polym- orphism (4G/5G) at -675 bp in promoter region of the PAI-1 gene is the major genetic determi- nant of PAI-1 expression. Plasma PAI-1 level is higher in people with the homozygous 4G genotype than in those with the 5G/5G genotype and renders higher transcription activity. The aim of this study was to determine the status and the role of PAI-1 gene 4G/5G promoter polymorphism in patients with Buerger's disease (Thromboangiitis obliterans—TAO). The current case-control study included 30 consecutive pat- ients with Buerger's disease (mean age 42.9 ± 14.3 years, 28 men and 2 women), and 30 healthy volunteers (mean age 40.9 ± 4.79 years, 27 men and 3 women) between January 2006 and September 2009. Patients and control cases were genotyped for the 4G/5G polymorphism using the multiplex PCR based stripassay reverse hybridisation technique. It was found that heterozygote PAI-1 gene polymorphisms (p < 0.05) was significantly more frequent in patients with TAO in the current results. There was a significant difference in genotype distribution between the two groups (P < 0.001). The 4G allele occurred more frequently in the patient group of heavy smokers (P = 0.05). The current study shows the higher prevalence of of 4G allele in TAO patients in Sivas population means gene may predispose to TAO.

Correlation of peripheral blood NF-κB expression with cytokines and endothelial injury in patients with thromboangiitis obliterans

Objective:To study the correlation of peripheral blood nuclear factorκB (NF-κB) expression with cytokines and endothelial injury in patients with thromboangiitis obliterans (TAO).Methods:Patients who were diagnosed as lower limb thromboangiitis obliterans in Jining No. 1 People's Hospital between March 2014 and October 2017 were selected as the TAO group of the research, and healthy subjects who received physical examination in Jining No. 1 People's Hospital during the same period and had the general information matching that of TAO group were selected as the control group. The NF-κB expression intensity in peripheral blood as well as the contents of cytokines and endothelial injury indexes in serum was determined.Results: NF-κB expression intensity in peripheral blood of TAO group was significantly higher than that of control group;serum ICAM-1, VCAM-1, E-selectin, TGF-β1, IL-10, TXB2, vWF, D-D, HIF-1 and VEGF levels of TAO group were significantly higher than those of control group whereas 6-Keto-PGF1 level was significantly lower than that of control group, and serum ICAM-1, VCAM-1, E-selectin, TGF-β1, IL-10, TXB2, vWF, D-D, HIF-1 and VEGF levels of TAO group of patients with high NF-κB expression were significantly higher than those of patients with low NF-κB expression whereas 6-Keto-PGF1 level was significantly lower than that of patients with low NF-κB expression.Conclusion: The high expression of NF-κB in the peripheral blood of patients with TAO can promote the excessive secretion of inflammatory and immune cytokines and aggravate the endothelial cell injury.

Si-Miao-Yong-An Decoction alleviates thromboangiitis obliterans by regulating miR-548j-5p/IL-17A signaling pathway

Thromboangiitis obliterans(TAO)is a rare,chronic,progressive,and segmental inflammatory disease characterized by a high rate of amputation,significantly compromising the quality of life of patients.Si-Miao-Yong-An decoction(SMYA),a tradition-al prescription,exhibits anti-inflammatory,anti-thrombotic,and various other pharmacological properties.Clinically,it was fully proved to be effective for TAO therapy,but the specific therapeutic effect of SMYA on TAO has been unknown.Thus,deep unveiling the mechanism of SMYA in TAO for identifying clinical therapeutic targets is extremely important.In this study,we observed elev-ated levels of IL-17A in the peripheral blood mononuclear cells(PBMCs)of TAO patients,whereas the expression of miR-548j-5p was significantly decreased.A negative correlation between the levels of miR-548j-5p and IL-17A was also demonstrated.In vitro ex-periments showed that overexpression of miR-548j-5p led to a decrease in IL-17A levels,whereas downregulation of miR-548j-5p showed the opposite effect.Using a dual luciferase assay,we confirmed that miR-548j-5p directly targets IL-17A.Furthermore,serum containing SMYA effectively decreased IL-17A levels by increasing the expression of miR-548j-5p.More importantly,the results of in vivo tests indicated that SMYA mitigated the development of TAO by inhibiting IL-17A through the upregulation of miR-548j-5p in vascular tissues.In conclusion,SMYA significantly enhances the expression of miR-548j-5p,thereby reducing the levels of the target gene IL-17A and alleviating TAO.Our research not only identifies novel targets and pathways for the clinical diagnosis and treatment of TAO but also advances the innovation in traditional Chinese medicine through the elucidation of the SMYA/miR-548j-5p/IL-17A regulatory axis in the pathogenesis of TAO.

Protective Effects and Potential Mechanism of Tongxinluo on Mice with Thromboangiitis Obliterans Induced by Sodium Laurate

Objective To investigate the effects of Tongxinluo(TXL)on thromboangiitis obliterans(TAO)and the underlying mechanisms.Methods Ninety male C57/BL6J mice were randomly divided into 6 groups according to a random number table:the sham group,TAO model group,Compound Danshen Tablet(CDT)group,and the high-,medium-,and low-dose TXL groups.All mice except the sham group were injected with sodium laurate(0.1 mL,5 mg/mL)in the femoral artery to establish TAO mouse model.After modeling,mice in the sham and TAO model groups were intragastrically administered 0.5%(w/v)sodium carboxymethylcellulose,mice in the CDT group were intragastrically administered 0.52 g/kg CDT,and mice in the TXL-H,TXL-M,and TXL-L groups were intragastrically administered 1.5,0.75,and 0.38 g/kg TXL,respectively.After 4 weeks of gavage,the recovery of blood flow in the lower limbs of mice was detected by Laser Doppler Imaging.The pathological changes and thrombosis of the femoral artery were observed by morphological examination.The expressions of tumor necrosis factorα(TNF-α)and inducible nitric oxide synthase(iNOS)in the femoral artery wall were detected by HE staining.Levels of thromboxane B2(TXB2),6-keto-prostaglandin F1α(6-keto-PGF1α),endothelin-1(ET-1),interleukin(IL)-1βand IL-6 were measured using enzyme-linked immunosorbent assay(ELISA).Levels of activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT)and fibrinogen(FIB)were detected by a fully automated biochemical analyzer.Results TXL promoted the restoration of blood flow in the lower limbs,reduced the area of thrombosis in the femoral artery,and alleviated the pathological changes in the femoral artery wall.Moreover,the levels of TXB2,ET-1,IL-6,IL-1β,TNF-αand iNOS were significantly lower in the TXL groups compared with the model group(P<0.05 or P<0.01),while the level of 6-keto-PGF1αwas significantly higher(P<0.01).In addition,APTT,PT,and TT were significantly prolonged in TXL groups compared with the model group(P<0.05 or P<0.01),and FIB levels were significantly decreased compared with the model group(P<0.01).Conclusions TXL had a protective effect on TAO mice,and the mechanism may involve inhibition of thrombosis and inflammatory responses.TXL may be a potential drug for the treatment of TAO.
