RESUMO

Objectives: To compare the impact of ticagrelor or clopidogrel on serum uric acid levels among patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) and further evaluate the effects of variation of serum uric acid levels on platelet reactivity. Methods: STEMI patients who admitted to Fuwai Hospital from April 2017 to January 2020, and underwent primary PCI and discharged alive with aspirin and ticagrelor or clopidogrel were included in this study. Patients were divided into ticagrelor group and clopidogrel group. The baseline clinical data were collected. Serum uric acid and creatinine levels at baseline and 30 days post-PCI were measured. Light transmittance aggregometry was used to assess maximum aggregation rate induced by adenosine diphosphate and arachidonic acid. The changes of serum uric acid and creatinine were compared between the two groups. Multivariate logistic regression was performed to evaluate independent related factors for rise in the uric acid levels, and the effect of variation of serum uric acid level on platelet reactivity was analyzed. Results: A total of 967 patients were included, the age was (59.4±12.1) years, and 163 case were female. There were 550 cases in ticagrelor group (56.9%) and 417 cases in clopidogrel group (43.1%). Baseline serum uric acid and creatinine levels were similar between the 2 groups. At 30 days, the serum uric acid level [(347.2±96.5) mmol/L vs. (341.2±105.3) mmol/L, P=0.009] and absolute [46.4 (-2.4, 88.1) mmol/L vs. 25.0 (-21.9, 73.0) mmol/L, P=0.001] and percentage [13.2 (-0.01, 29.0) % vs. 7.9 (-5.7, 25.0) %, P=0.007] increase in the serum uric acid levels were significantly higher in ticagrelor group than in clopidogrel group. The level of serum creatinine at 30 days was significantly lower in ticagrelor group than in clopidogrel group [(89.7±21.3) µmol/L vs. (94.4±43.9) µmol/L, P<0.05], whereas there were no differences in absolute [8.0 (-1.4, 16.6) µmol/L vs. 7.8 (-2.0, 16.6) µmol/L] and percentage [10.5 (-1.7%, 22.6%) vs. 9.8 (-2.4%, 22.1%)] change in the serum creatinine between the 2 groups (all P>0.05). Logistic regression analysis showed that, after adjusting for confounding factors, ticagrelor therapy was an independent related factor of serum uric acid elevation (OR=1.582, 95% CI:1.023-2.447, P=0.039). The variation of the serum uric acid levels did not affect platelet aggregation and the percentage of high platelet reactivity in both groups. Conclusions: Ticagrelor use is related to a significant increase in the serum uric acid levels at 30 days post-PCI in this patient cohort. The variations in the uric acid levels do not increase the percentage of high platelet reactivity in STEMI patients treated with ticagrelor or clopidogrel.

RESUMO

Objective: To evaluate the 4-year clinical outcomes of patients following Firesorb bioresorbable scaffold (BRS) implantation. Methods: The study reported the 4-year follow-up results of the FUTURE I study. FUTURE I was a prospective, single-center, open-label, first-in-man study which evaluated the feasibility, preliminary safety, and efficacy of Firesorb stent in the treatment of coronary artery stenosis. A total of 45 patients with single de novo lesions in native coronary arteries ,who hospitalized in Fuwai Hospital from January to March 2016 were enrolled. After successfully stent implantation these patients were randomized in a 2∶1 ratio into cohort 1 (n=30) or cohort 2 (n=15). The patients in cohort 1 underwent angiographic, IVUS or OCT examination at 6 months and 2 years; and cohort 2 underwent angiographic, IVUS or OCT at 1 and 3 years. All patients underwent clinical follow-up at 1, 6 months and 1 year and annually thereafter up to 5 years. The primary endpoint was target lesion failure (TLF, including cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization). Secondary endpoints included patient-oriented composite endpoint (PoCE, defined as composite of all death, all miocardial infarction, or any revascularization). Results: A total of 45 patients were enrolled and implanted with Firesorb BRS, including 35 males (77.8%), and the age was (54.4±9.3) years. At 4 years, 10 patients in cohort 1 were reexamined by coronary angiography and OCT examination. Among them, 2 patients' stents were completely degraded and absorbed. Compared with the OCT images of the other 8 patients in cohort 2 at 3 years, the degree of stent degradation was increased, and no stent adherence was found. The 4-year clinical follow-up rate was 100%. In 4-year clinical following up, 2 patients suffered PoCE (4.4%): 1 patient underwent non-target vessel revascularization the day after index procedure and target vessel revascularization (Non-target lesion revascularization) at 2-year imaging follow-up; the other patient underwent target lesion revascularization during imaging follow-up at 4 years but not due to ischemic driven. There was no scaffold thrombosis or TLF events through 4 years. Conclusions: Four years after the implantation, complete degradation and absorption of the Firsorb stent are evidenced in some patients. Firesorb stent is feasible and effective in the treatment of patients with non-complex coronary lesions.

RESUMO

Objective: To compare the long-term outcomes in ST-elevation myocardial infarction (STEMI) patients who underwent early or late delayed percutaneous coronary intervention (PCI) using drug-eluting stents (DES). Methods: This study was a retrospective, observational and single-center study. Consecutive STEMI patients (n=977), who admitted to Fuwai Hospital in 2013 and underwent successful selective PCI using drug-eluting stents (DES) within 3 to 35 days after symptom onset were enrolled and divided into the early delayed PCI (3-14 d) group (n=495) and the late delayed PCI (15-35 d) group (n=482). General clinical data of the patients and related data of coronary angiography and interventional therapy were collected, and the endpoint events were followed up. The primary endpoint was 2-year major adverse cardiac and cerebrovascular events (MACCE) including cardiac death, recurrent myocardial infarction, definite or probable stent thrombosis and ischemic stroke. The secondary endpoint was 2-year ischemia-driven target vessel revascularization. The incidence of endpoint events of the two groups was compared, and it was compared again after the primary baseline characteristics such as age and gender were matched by the propensity scoring method at a 1∶1 ratio. Results: A total of 910 (93.1%) patients who underwent delayed PCI were transferred from other hospitals, and 292 (29.9%) patients received thrombolysis before PCI. The time interval before PCI was 14 (10, 20) days. The incidence of 2-year MACCE (3.0%(15/495) vs. 2.3%(11/482), P=0.468) and ischemia-driven target vessel revascularization (3.8%(19/495) vs. 5.0%(24/482), P=0.385) were similar between the two groups. The incidence of 2-year MACCE (3.3%(15/453 vs. 2.4%(11/453), P=0.426) and ischemia-driven target vessel revascularization (4.2% (19/453) vs. 4.9%(22/453), P=0.632) were also similar between the two groups after matching propensity score. Conclusion: The long-term clinical outcomes after early delayed PCI using DES is statistically equivalent to those of late delayed PCI using DES for STEMI patients who missed the time window for emergency PCI.

RESUMO

Objective: To compare the 6-month follow-up results of primary percutaneous coronary intervention (PPCI) guided by optical coherence tomography (OCT) or coronary angiography (CAG) alone in a larger ST-segment elevation myocardial infarction (STEMI) cohort. Methods: We enrolled 275 STEMI patients undergoing OCT-guided PPCI from March 2017 through December 2018. Two hundred and seventy-five propensity score matched STEMI patients undergoing CAG-guided PPCI served as control group. The 6-month clinical follow-up results were compared between the two groups. The demographic data, complications, coronary angiography and OCT characteristics were evaluated. Results: OCT evaluation showed that there were 151 patients (54.9%) with plaque prolapse and 113 patients (41.1%) with stent malposition. Proximal and/or distal dissection of stents occurred in 38 patients (13.8%), of which 3 patients (1.1%) had both proximal and distal dissection. Of the 38 patients, 2 patients received rescue stent implantation. Results of clinical follow-up at 6 months showed that there was no significant difference in cardiovascular death, repeat myocardial infarction, target vessel revascularization, stroke and hemorrhage endpoint events between OCT-guided PPCI patients and CAG-guided PPCI patients (P=0.682). Conclusion: Clinical events at 6 months are similar between OCT-guided PPCI and CAG-guided PPCI for STEMI patients.

RESUMO

Objective: To investigate the association between postprocedural D-dimer, high sensitivity C-reactive protein(hs-CRP) and low-density lipoprotein-cholesterol(LDL-C) and outcomes of acute myocardial infarction (AMI) patients treated by percutaneous coronary intervention(PCI), in order to clarify the impacts of thrombotic, inflammatory and cholesterol risks on long-term prognosis. Methods: Patients with AMI who underwent emergency PCI from January 2010 to June 2017 in Fuwai Hospital with complete baseline data were enrolled. Patients were stratified into four groups according to quartiles of D-dimer, hs-CRP and LCL-C. Cox regression was used to analyze the relationship between these biomarkers and prognosis. Restricted cubic spline (RCS) was used to characterize the continuous association between risk of all-cause death and biomarkers. The primary outcome was all-cause death. Results: A total of 3 614 patients were included in the analysis. The age was (59.2±12.0) years old, and 2 845 (78.7%) were male and 3 161 (87.5%) patients were diagnosed as ST-segment elevation myocardial infarction. The follow-up time was 652 (414, 1 880) days. Survival analysis showed that postprocedural D-dimer and hs-CRP were significantly associated with all-cause mortality (all P<0.05). Cox regression with multiple adjustments showed that patients with D-dimer≥580 µg/L presented higher risk of all-cause death (HR=2.03, 95%CI 1.22-3.38, P=0.006), compared to patients with D-dimer<220 µg/L. RCS analysis showed that risk of all-cause death was stably high when D-dimer reached 500 µg/L. Multivariable Cox regression also showed that patients with hs-CRP<2.74 mg/L (HR=1.86, 95%CI 1.10-3.15, P=0.020)or hs-CRP≥11.99 mg/L (HR=2.14, 95%CI 1.35-3.40, P=0.001) presented higher mortality compared to patients whose hs-CRP was 2.74-7.18 mg/L. RCS analysis indicated a J-shaped relation between hs-CRP and mortality, as greater risk of death was observed when hs-CRP was lower than 2 mg/L or higher than 10 mg/L. LDL-C was not associated with outcomes (all P>0.05). Conclusions: Postprocedural D-dimer is significantly associated with long-term prognosis of AMI patients treated by PCI. Patients with extremely high or low levels of hs-CRP presents worse outcomes. Intensive and tailored antithrombotic or anti-inflammatory therapies should be considered for patients with increased thrombotic risk and those with extremely high or low inflammatory risk.

RESUMO

Echinococcus granulosus sensu stricto is regarded to have the highest zoonotic potential of all Echinococcus taxa. Globally, human infection due to this species constitutes over 88.44% of the total cystic echinococcosis (CE) burden. Here, we report a CE infection in a Nigerian camel caused by E. granulosus G1 genotype. To the best of our knowledge, this report is the first encounter of the G1 genotype in the West Africa sub-region where the G6 genotype is reportedly prevalent, suggesting that the epidemiology of this highly zoonotic group could have a wider host range and distribution in the sub-region, and emphasizes the need for further investigation into the genetic diversity of Echinococcus spp. in Nigeria and across the sub-region.

RESUMO

Objective: To investigate the clinical features and change trend of patients with acute coronary syndrome(ACS) undergoing emergent percutaneous coronary intervention(PCI). Methods: In this retrospective study, we retrieved all medical records of 4 907 ACS patients who underwent emergent PCI in Fuwai hospital from January 1,2010 to December 31,2016. We analyzed the clinical features and change trend in these patients. According to clinical diagnosis, patients were grouped as ST-elevated myocardial infarction(STEMI) group (3 719 cases) and NSTE-ACS group (patients with non-STEMI and unstable angina, 1 188 cases). Results: The ACS patients were aged (59.5±11.8) years old. There were 3 772 males and 1 135 females. The annual number of ACS patients underwent emergent PCI increased from 412 patients in 2010 to 1 067 patients in 2016. The number of NSTE-ACS patients increased from 11.4% (47/412) in 2010 to 26.5% (283/1 067) in 2016. Compared with STEMI group, patients in NSTE-ACS group were significantly older ((61.2±10.9) years old vs. (58.9±12.1) years old,P<0.01).The percent of female patients (30.1% (358/1 188) vs. 20.9% (777/3 719), P < 0.01), history of hypertension (69.1% (821/1 188) vs. 60.4% (2 248/3 719,P <0.01), previous PCI (25.8% (307/1 188) vs. 12.4% (461/3 719), P <0.01), and previous coronary artery bypass grafting (3.0% (36/1 188) vs. 1.0% (37/3 719), P <0.01) were all significantly higher in NSTE-ACS group than in STEMI group. On the other hand, NSTE-ACS patients presented less chronic renal failure (2.9% (35/1 188) vs. 4.3% (173/3 719), P <0.05) and hepatic dysfunction (8.5% (101/1 188) vs. 13.3% (495/3 719), P<0.01) as compared to ACS patients. In coronary angiography, NSTE-ACS patients had a higher prevalence of left-main disease (14.0% (166/1 188) vs. 7.8% (291/3 719), P<0.012 5) and triple vessel disease (47.8% (568/1 188) vs. 43.5% (1 619/3 719), P<0.012 5). There were no differences in prevalence of diabetes mellitus (31.9% (1 187/3 719) vs. 34.8% (414/1 188),P>0.05) and acute renal failure (0.1% (38/3 719) vs. 0.6% (7/1 188),P>0.05) between STEMI group and NSTE-ACS group. Conclusions: This single center retrospective analysis reveals that there is an increasing trend of NSTE-ACS patients from 2010 to 2016. Furthermore, there are more high-risk clinical characteristics in NSTE-ACS patients than in STEMI patients.

RESUMO

Objective: To compare the safety of continued warfarin therapy and bridging anticoagulation therapy during hospital stay in patients undergoing percutaneous coronary intervention (PCI). Methods: We retrospectively analyzed patients on warfarin therapy referred for PCI in Beijing Anzhen Hospital from January 2008 to December 2016. The patients were divided into continued warfarin therapy (n=195) or bridging anticoagulation therapy (n=311) groups. After Propensity Score Matching, data from matched patients (n=123 in each group) were analyzed. Bleeding complications and major adverse cardiac events including death, myocardial infarction, target vessel revascularization, and stent thrombosis were assessed. Results: There were no significant difference in the rate of death (2.4%(3/123) vs. 1.6%(2/123),P=0.54), acute myocardial infarction (4.1%(5/123) vs. 4.9%(6/123), P=0.78),re-revascularization (0.8%(1/123) vs. 1.6%(2/123),P=0.16), stent thrombosis (1.6%(2/123) vs. 1.6%(2/123),P=1.00) and stroke between the two groups. Prevalence of minor bleeding complications was significantly higher in the bridging therapy group (15.4%(19/123) vs. 9.8%(12/123),P=0.01). Rate of access-site complications (hematoma:4.1%(5/123) vs. 2.4%(3/123),P=0.20; pseudoaneurysm:2.4%(3/123) vs. 2.4%(3/123),P=1.00; arteriovenous fistula:0.8%(1/123) vs. 1.6%(2/123),P=0.09; and retroperitoneal hematoma:0(0/123) vs. 0.8%(1/123),P=0.23) were similar between the two groups. Conclusion: For patients receiving chronic warfarin therapy, the uninterrupted oral anticoagulant treatment is as safe as bridging therapy in PCI patients.

RESUMO

Objective: To investigate the degree and determinants of using ticagrelor among discharged patients with acute coronary syndrome (ACS). Methods: Patients with ACS in Fuwai hospital who were given ticagrelor after discharge between Jan. 2015 to Jun. 2015 were analyzed.The clinical characteristics and adherence to ticagrelor of these patients were collected by reviewing the electronic medical records and telephone interview.Date were statistically-analyzed. Results: Among all screened 404 patients, 158 (39.1%) patients prematurely stopped ticagrelor within 12 months, while 119(29.5%) patients switched from ticagrelor to clopidogrel.Unavailable locally (34.8%), economic reasons (17.7%) and hemorrhagic events (18.4%) were the main causes of the premature discontinuation of ticagrelor.Univariate analysis showed left main disease (P=0.04) and the frequency of outpatient follow-up (P<0.01) as relative factors for prematurely stopping ticagrelor outside hospital after discharge.Multivariate analysis revealed medical insurance payment (OR 1.79, 95%CI 1.03-3.11) and the frequency of outpatient follow-up (OR 0.61, 95%CI 0.43-0.86) as independent predictors of prematurely stopping ticagrelor outside hospital.Prematurely stopping ticagrelor has no significant effect on the ischemic events (myocardial infaction or stroke) (P=0.76). Conclusion: Social cinditions is the main factor for the persistence to ticagrelor among ACS patients after dischcrge.Medical insurance payment and low frequency of outpatient follow-up were independent predictors of prematurely stopping ticagrelor and it may not have impact on ischemic events.

RESUMO

Vaccination as a preventative strategy against Trichinella spiralis infection is an ongoing effort, although no ideal vaccine candidates have been identified until now. Identification of more effective antigens that have a role in essential life stages of the parasite and that may be effective vaccine candidates is therefore of importance. In the present study, we identified a novel aquaporin gene (TsAQP) from T. spiralis, and the potential antigenicity of TsAQP was evaluated by epitope prediction. A total of 11 post-translational modification sites were predicted in the protein and fell into 4 categories: N-glycosylation; casein kinase II phosphorylation; protein kinase C phosphorylation; and N-myristoylation sites. TsAQP is a membrane intrinsic protein with high hydrophobicity; the main hydrophobic domains comprised up to 38.5% of the protein and were distributed at amino acid positions 21-43, 54-71, 83-91, 107-121, 163-174, 187-200, and 242-261. The protein consisted mainly of helices (39.58%) and loops (50%). The advanced structure of TsAQP was predicted using homology modeling, which showed that the protein was formed from 6 membrane-spanning domains connected by 5 loops. Based on these analyses, 6 potential B-cell epitopes and 4 potential T-cell epitopes were further predicted. These results suggest that TsAQP could be a promising antigen candidate for vaccination against T. spiralis.

RESUMO

We investigated the effect of neural stem cells (NSC) and erythropoietin (EPO) on axon regeneration in adult rats with transected spinal cord injury, and provided an experimental basis for clinical treatment. Forty Wistar rats with T10-transected spinal cord injury were randomly divided into four groups of ten rats: a control group (group A), an NSC-transplant group (group B), an NSC-transplant and EPO group (group C), and an EPO group (group D). Biotinylated dextran amines (BDA) anterograde corticospinal cord neuronal tracing and Fluoro-Gold (FG) retrograde tracing were carried out at the 8th week after operation to observe the regeneration of nerve fibers. The Basso, Beattie, and Bresnahan (BBB) locomotor score was used to evaluate restoration. 1) BDA and FG immunofluorescence staining: in group C, a large number of regenerated axons were observed and some penetrated the injured area. In group B, only a small number of regenerated axons were observed and none penetrated the injured area. In group D, only sporadic regenerated nerve fibers were observed occasionally, while in group A, no axonal regeneration was observed. In group C, a small number of cones and axons emitted yellow fluorescence, and no FG-labeled cells were observed in the other groups. 2) The BBB scores for group C were higher than those for the other groups, and the differences were statistically significance (P < 0.05). NSC transplantation combined with EPO intraperitoneal injection may benefit axon regeneration in rats with transected spinal cord injury, and accelerate the functional recovery of the hindlimb locomotor.

RESUMO

The 5'-adenosine monophosphate-activated protein kinase (AMPK) is an energy sensor that regulates cellular metabolism. 5'-Adenosine monophosphate-activated protein kinase controls glucose and lipid metabolism in skeletal muscle, liver, and adipose tissues. The aim of this study was to investigate the effects of AMPK on glucose and lipid metabolism in dairy goat mammary epithelial cells. Treatment of mammary epithelial cells with an AMPK activator (5-aminoimidazole-4-carboxamide 1-ß-D-ribofuranoside) dramatically increased glucose uptake and glucose transporter-1 mRNA abundance, and decreased levels of glycogen synthase 1 mRNA. Activation of AMPK also induced an increase in carnitine palmitoyl transferase 1 mRNA and decreases in fatty acid synthase and acetyl-CoA carboxylase 1 mRNA. These results suggest that AMPK is involved in the regulation of energy metabolism in dairy goat mammary epithelial cells.

RESUMO

Taenia multiceps is an adult worm affiliated to Taeniidae family, Platyhelminthes phylum. The larvae of the parasite (Coenurus cerebralis) parasitic in the brain and spinal cord in domestic and wild ruminants or humans can led to a fatal central nervous system (CNS) disease. The aims of the present study were to define the transcriptome profiles of the larvae of T. multiceps by RNA-Seq approach, and to generate large functional gene datasets that could be used to predict the key molecular pathways linked to this cestode. Our results generated a total of 39,094,890 clean reads that were assembled from the sequence data in 90,833 contigs. Briefly, 70,253 unigenes with a mean length of 1492bp were formed. Based on a sequence similarity search against the databases (NR, Swissport, GO, COG, KEGG) using BLASTX with an E-value cutoff of 10-5, 40,465 of unigenes were identified as coding sequences (CDS) and 3261 were scanned by ESTScan. The present study carried out the transcriptome of the larval stage of T. multiceps, which provides a solid foundation for further studies in molecular biology and biochemistry as well as identification of candidate genes used in diagnosis and vaccine development.

RESUMO

Trichinella spiralis, an intracellular parasitic nematode, can cause severe foodborne zoonosis, trichinellosis. The life cycle of T. spiralis consists of adult (Ad), muscle larvae (ML) and newborn larvae (NBL). The protein profiles in different developmental stages of the parasite remain unknown. In the present study, proteins from lysates of Ad, ML and NBL were identified by isobaric tags for relative and absolute quantitation (iTRAQ). A total of 4691 proteins were identified in all the developmental stages, of which 1067 proteins were differentially expressed. The number of up-regulated proteins in NBL was higher than that of the other two groups. The protein profiles from Ad, ML and NBL were compared in pairs. The identified proteins were involved in various functions of T. spiralis life cycle, including sexual maturity, metabolism, utilization of carbohydrates, lipids and nucleotides, and other crucial developmental processes that occur at distinct stages. Further investigation of the transcriptional levels of major sperm protein, serine protease, zinc finger protein, etc. from the different protein profiles using quantitative RT-PCR showed identical results to the iTRAQ analysis. The differentially expressed proteins that are involved in developmental regulation and host-parasite interactions should be further studied.

RESUMO

Twenty-three cases of spinal extradural tumors were differentiated with CT myelography. In 16 benign tumors, the proximal and/or distal widened extradural space was filled with adipose tissue, whereas in 7 malignant tumors, the widened extradural space showed soft-tissue density. This difference is helpful in evaluating the nature of the tumors.

RESUMO

Coenurosis is a parasitic disease caused by the larval stage of Taenia multiceps, which affects various ruminants species, particularly sheep and goats, and occasionally humans. In this note, non-cerebral coenurosis in goats with the goal to compare morphological and biomolecular characteristics is focused in order to determine if the non-cerebral specimens should be considered a new specie or a strain of T. multiceps. Three hundred goats slaughtered with macroscopic lesions due to the presence of metacestodes were examined in an abattoir in Dubai, United Arab Emirates in order to evaluate the presence of extra-cerebral coenuri. Forty-eight coenuri were found under the skin, between fasciae of the skeletal muscles, diaphragm and in the abdominal cavities. Morphologically, the examined non-cerebral coenuri recovered showed the same features reported by other authors for Coenurus cerebralis, but their location outside the central nervous system suggests that they may be a different strain or genetic variants of T. multiceps. Nine caprine coenuri were then processed for sequencing of mitochondrial partial COI (396 bp) and ND1 (471 bp) genes indicating that they had a pairwise distance of 1.0-1.3% and 2.4-4.1% compared with parasite' COI sequences from Italy (Tm1-Tm3 strains) and Erzurum strains of ovine origin, respectively; whereas it had 0.6-1.3% and 0.4-1.1% pairwise distance for ND1. Phylogenetic trees of their ND1 and COI sequences using the maximum composite likelihood method with MEGA showed that these nine parasites recovered in Emirates abattoir could be grouped into a new strain. In conclusion, morphological and molecular characterization of caprine coenurosis from Dubai, United Arab Emirates, shows that the specimens are significantly different from other strains or genotypes in COI sequence, which suggests that they should belong to different genotypes or strains of T. multiceps.
