Objective To study the risk factor and prognosis of concurrent depression in elderly patients with acute myocardial infarction (AMI) treated with percutaneous coronary intervention (PCI). Methods Two hundred and ninety-five AMI patients who received PCI and whose clinical data were complete were selected. Depression was determined by a self-rating scale (SDS), and was confirmed when SDS standard score≥53 scores. The patients were divided into 2 groups according to the ages:senium (age ≥ 60 years, 144 cases) group and younger group (age<60 years, 151 cases). Multiple Logistic regression analysis was used to analyze the related factors of depression. The patients were followed up for 1 year, and the rehospitalization rate, incidence of major adverse cardiovascular events (MACE) and left ventricular ejection fraction (LVEF) at 12 months were compared. Results The incidence of depression in senium group was significantly higher than that in younger group: 41.7%(60/144) vs. 21.2%(32/151), and there was statistical difference (P<0.05). Female gender, hypertension and type 2 diabetes mellitus were the independent risk factor for depression in patients with AMI after PCI (P<0.05). In senium group, the rehospitalization rate and incidence of MACE in patients with depression were significantly higher than those in patients without depression: 18.3% (11/60) vs. 6.0% (5/84) and 15.0% (9/60) vs. 4.8%(4/84), the LVEF was significantly lower than that in patients without depression:(41.50 ± 2.25)%vs. (49.76 ± 2.93)%, and there were statistical differences (P<0.05). The LVEF in patients with depression of senium group was significantly lower than that in patients with depression of younger group:(41.50 ± 2.25)%vs. (51.50 ± 2.32)%, and there was statistical difference (P<0.05). Conclusions The elderly AMI patients treated with PCI have higher rates of depression. Female gender, hypertension and type 2 diabetes mellitus are the important risk factor for depression after PCI. Depression has a significant effect on the prognosis of AMI patients, especially on LVEF in elderly patients.

Objective To study the radiological features of dynamic enhanced multi-slice spiral CT (MSCT) and CTA in pure hepatic arterio-venous fistula (AVF).Methods The radiological features of MSCT imaging and CTA of 100 patients with pure hepatic AVF were retrospectively analyzed.Results Positive signs on the arterial phase were detected in 100 patients with pure hepatic AVF.In 89 patients,they were the peripheral type and in 11 patients they were the central type.There were 128 lesions in the 100 patients.In the peripheral type,the features were (1) in the arterial phase,the lesions appeared as a wedged or a patchy enhancement area at the edge of the liver,showing a halo sign in 68 patients.In 56 patients,the PV was shown also in the early arterial phase;(2) in the arterial phase,arailway track sign was shown in 21 patients as a result of a portal vein branch showing right next to a hepatic arterial branch.In the central type and in the arterial phase,the main portal vein (or the hepatic vein) and the left/right branches of the PV (or the HV) were shown.Conclusion MSCT and CTA were useful in the diagnosis of pure hepatic AVF.

Objective:To analyze the clinical characteristics of patients with eosinophilic granulo-matosis with polyangiitis (EGPA) and improve the understanding of the disease.Methods:EGPA patients who fulfilled the 1990 American College of Rheumatology (ACR) classification criteria were recruited from Sun Yat-sen Memorial Hospital Sun Yat-sen University between December 2003 and April 2020. Their demographic characteristics, clinical manifestations, laboratory and auxiliary examinations were analyzed retrospectively. Mann-whitney U test and χ2 test were used for statistical analysis. Results:Among 52 EGPA patients, 34 (65.4%) were males and the median age at disease onset was 47(38-55) years. The median time from disease onset to diagnosis was 30(4-96) months. The most common initial symptoms were respiratory (61.5%) and nose/paranasal sinus (21.2%) involvement. The most common department for the first visit was respiratory medicine (53.8%), followed by rheumatology (11.5%). 44.2% EGPA patients were diagnosed by rheumatologists. The most common clinical manifestations were asthma (88.5%), nose/paranasal sinusitis (84.6%), pulmonary (76.9%) and nervous system (61.5%) in volvement. Eight(15.4%) patients were positive for antineutrophil cytoplasmic antibodies (ANCA). Patients with positive ANCA had lower incidence of asthma, but higher incidence of general symptoms especially arthralgia and renal involvement, elevated eosinophil count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Birmingham vasculitis activity score and vasculitis damage index than patients with negative ANCA (all P<0.05). 21.2%-34.6% EGPA patients had poor prognostic factors. Conclusion:Early diagnosis of EGPA is important. EGPA patients with positive ANCA may be more severe than patients with negative ANCA. The management should be a multi-disciplinary collaboration between rheumatologists and pulmonologists.

Objective:To study the protective effects of Danhong injection ( DH) on myocardial damage induced by doxorubicin ( DOX) in Lewis tumor bearing mice. Methods:The model of Lewis lung cancer in mice was established by underarm injecting tumor cells, and then randomly divided into four groups:the model control group, DOX group, DH group and DH+DOX group. After the experiment, myocardial and tumor tissue were separated from Lewis tumor bearing mice, and the excised tumors were weighted. The activities of lactate dehydrogenase ( LDH) , creatine kinase ( CK) , manganese superoxide dismutase ( SOD) , catalase ( CAT) and glu-tathione peroxidase ( GPx) , and the content of malondialdehyde ( MDA) were determined by a colorimetric method. Flow cytometry was used to determine the levels of apoptosis, reactive oxygen species (ROS) and mitochondrial membrane potential (△Ψm). Re-sults:Compared with that in the model control group, a significant decrease of tumor weight was shown in both DOX group and DH+DOX group (P<0. 01). DH had no significant influence on the anticancer function of DOX. The activity of LDH and CK, and the ap-optosis in myocardium cells significantly increased (P<0. 01). Compared with DOX group, the activities of LDH and CK, and the ap-optosis significantly decreased in DH+DOX group (P<0. 01). The activities of △Ψm, SOD, CAT and GPx significantly increased (P<0.05orP<0.01). ThecontentofMDAandROSgenerationbothdecreased(P<0.01).Conclusion:DHhasnosignificantin-fluence on the antitumor effect of DOX. The combination of DH and DOX shows cadioprotective effect on the myocardial damage through improving mitochondrial antioxidant defense capacity, ameliorating oxidative stress and maintaining △Ψm homeostasis.

Objective To identify independent predictors of no-reflow after primary percutaneous coronary intervention (PPCI)in aged patients with ST-elevation acute myocardial infarction (STEMI), and thus construct a no-reflow predicting model.MethodsTotal of 668 aged patients with STEMI and successfully treated with PPCI were divided into the no-reflow group and the normal flow group. All clinical, angiographic and procedural data were collected. Multiple logistic regression analysis was used to identify independent no-reflow predictors.ResultsThe no-reflow was found in 181 of 668 (27.1％) patients.Multiple stepwise logistic regression analysis identified that admission systolic blood pressure (SBP)＜100 mm Hg, collateral circulation 0-1 grade, pre-PCI thrombus score ≥ 4, and intra-aortic balloon pump (IABP) use before PCI were independent noreflow predictors.The no-reflow incidence significantly enhanced as the numbers of independent predictors increased [10.0％ (2/20), 13.7％ (32/233), 30.8％ (85/276), 38.1％ (37/97), and 59.5％ (25/42) in patients with 0, 1, 2, 3, and 4 independent predictors, respectively,x2 =25.796,P＜0.01) ]. ConclusionsThe no-reflow predictors are admission SBP ＜ 100 mm Hg, collateral circulation 0-1grade, pre-PCI thrombus score≥4, and IABP use before PCI in patients with STEMI and treated with PPCI. The prediction model may provide basis for therapeutic decision.

Objective To assess independent no-reflow predictors in patients with STEMI after primary drug-eluted stenting.Method A prospective study was carried out in 1413 patients with STEMI treated with primary drug-eluted stenting within 12 hours after onset of AMI from January 2007 through March 2010.The patients were divided into the no-reflow group and the normal reflow group.Univariate and multivariate logistic regression were applied to identification of no-reflow predictors.Results The no-reflow was found in 297(21.0％)of 1413 patients.Univariate and multivariate logistic regression identified that age ＞65 years,long time from onset to reperfusion ＞6 hours,admission plasma glucose(APG)＞ 13.0mmol/L,collateral circulation ≤ 1,pre-percutaneous coronary intervention(PCI)thrombus score ≥ 4,and intra-aortic balloon pump(IABP)used before PCI(P ＜0.05)were independent no-reflow predictors.The no-reflow rate significantly increased as the number of predictors increased(P ＜ 0.01).Conclusions There are 6 factors associated with coronary no-reflow used for prediction in patients with STEMI after primary drug-eluted stenting.

Objective To assess the association between admission plasma glucose (APG) and noreflow during primary percutaneous coronary intervention (PCI) in patients with ST-elevation acute myocardial infarction (STEMI). Methods A total of 1413 patients with STEMI successfully treated with PCI were divided into no-reflow group and normal reflow group. Results The no-reflow was found in 297 patients (21.0%) of 1413 patients; their APG level was significantly higher than that of the normal reflow group [( 13.80 ±7.47) vs (9.67 ±5.79) mmol/L, P＜0.0001]. Multivariate logistic regression analysis revealed that current smoking ( OR 1.146, 95% CI 1.026-1. 839,P = 0.031), hyperlipidemia ( OR 1. 082,95% CI 1. 007-1. 162, P = 0. 032), long reperfusion ( ＞ 6 h, OR 1. 271, 95% CI 1. 158-1. 403, P =0. 001 ) , admission creatinine clearance ( ＜ 90 ml/min, OR 1.046, 95% CI 1. 007-1.086, P = 0.020 ) ,IABP use before PCI (OR 9.346, 95%CI 1.314-67. 199, P=0.026), and APG ( ＞ 13.0 mmol/L, OR1.269, 95% CI 1.156-1.402, P = 0.027) were the independent no-reflow predictors. The no-reflow incidence was increased as APG increased ( 14. 6% in patients with APG ＜ 7. 8 mmol/L and 36. 7% in patients with APG ＞ 13.0 mmol/L, P = 0.009 ). Conclusion APG ＞ 13.0 mmol/L is an independent noreflow predictor in patients with STEMI and PPCI.

ObjectivesTo examine the validity of high-frequency Doppler ultrasound in identifying knees synovitis in patients with rheumatoid arthritis(RA).MethodsNinety-five consecutive patients with active RA were examined withhigh-frequency Doppler ultrasound to examine synovitis signals in knees.Synovial tissue samples of 51 patients were obtained by closed needle biopsy from knees after ultrasound examination.Serial synovial tissue sections were stained with H&E and immunohistochemical staining,and the histopathological synovitis scores were evaluated.The relationship among clinical, histopathological and ultrasound synovitis indexes was analyzed by Spearman's rank order correlation test and receiver operating characteristic curve analysis.ResultsAmong 95 RA patients,the median thickness of synovial membrane in ultrasound was 2.8 mm,the median depth of effusion was 2.7 mm; Doppler signals of synovial blood flow were detected in 82％(78/95 ) of patients and the median semiquantitive grading of synovial blood flow was 1.0.The thickness of synovial membrane and synovial blood flow at Doppler ultrasound correlated positively with histological synovitis score,hyperplasia of the lining layer,and inflammatory infiltration in sublining area (the thickness of synovial membrane:r=0.438,0.424,0.368,respectively; synovial blood flow:r=0.357,0.377,0.347,respectively; all P＜0.05).Although there was no significant difference in clinical synovitis indexes between patients with histologically low-grade and high-grade synovitis,the thickness of synovial membrane and synovial blood flow in ultrasound in patients with histologically high-grade synovitis was significantly higher than those with low-grade synovitis(P=0.001,0.036,respectively).When the thickness of synovial membrane in ultrasound was ≥ 3.9 mm,the specificity of diagnosing the high-grade synovitis was 96.7％ and the sensitivity was 61.9％.ConclusionSynovitis signals at high-frequency Doppler ultrasound correlate with histopathological synovitis,and it might be helpful in evaluating the severity of histopathological synovitis.

Objective To investigate doctor's screening practice for hepatitis B virus (HBV) infection before immunosuppressive therapy for rheumatoid arthritis (RA) patients and clinical management of RA patients with positive surface antigen of HBV (HBsAg).Methods One hundred fifty doctors who treated RA patients in daily clinic were survied with a modified American College of Rheumatology (ACR) questionnaire which was composed of demographic data and 10 multiple-choice questions.Step-forward logistic regression analysis was performed to find out the influencing factors,then receiver operator characteristic curve analysis and area under the curve were performed to confirm the influencing factors.Results One hundred and thirtytwo effective questionnaires were collected.Before immunosuppressive therapy,HBV screening rate in outpatients with RA was significandy lower than that in hospitalized patients (68.7％ vs 94.6％,x2=31.5,P＜0.01).Only 23.7％(31/131) of doctors considered antiviral treatment for all RA patients with positive HBsAg.One hundred and thirteen doctors had clinical experience of antiviral treatment,but only 30.1％(34/113) and 23.9％ (27/113) of these doctors chose entecavir or adefovir as the antiviral drug respectively,59.3％ (67/113) prescribed antiviral drug before or together with immunosuppressive therapy compared with 40.7％(46/113) after HBV reactivation.Only 20.4％(23/113) of doctors would sustain antiviral treatment until the termination of steroid or disease modifying antirheumatic drugs (DMARDs).During immunosuppressive therapy for HBsAg(+) RA patients,11.4％(15/132) and 30.3％(40/132) of doctors reported no regular monitoring of aminotransferase or HBV DNA respectively.Conclusion Our survey shows that HBV screening rate in outpatients with RA is low and low awareness of antiviral treatment for all RA patients with positive HBsAg,and lack of awareness of indication,choosing of antiviral drugs,initiation,monitoring and duration of antiviral treatment during immunosuppressive therapy.Further medical education on the associated information and importance to collaborate with hepatologists should be emphasized.
