Abstract
Objective: To investigate the relationship between thrombolysis in myocardial infarction risk index(TRI) and the severity of coronary artery lesions and long-term outcome in acute myocardial infarction(AMI) patients undergoing percutaneous coronary intervention(PCI). Methods: A total of 1 663 consecutive AMI patients undergoing PCI between January and December 2013 in Fuwai hospital were prospectively included in this study. The severity of coronary artery lesions was evaluated using the SYNTAX score. Receiver operating characteristic(ROC) curve was used to analyze the optimal cut-off value of TRI on predicting all-cause mortality at 2 years after PCI.The patients were divided into 2 groups based on the optimal cut-off value of TRI:high TRI group (TRI ≥ 23.05, 465 cases) and low TRI group(TRI<23.05, 1 198 cases). Multivariate logistic regression analyses were used for determining the relationship between TRI and SYNTAX scores≥33. A multivariate Cox regression analyses was used to identify the influence factors of long-term outcome after PCI. Results: SYNTAX score was higher in high TRI group than in low TRI group (13.00(7.00, 20.50) vs.10.25(7.00, 17.00), P<0.001). TRI was independently associated with SYNTAX score ≥ 33 (OR=1.09,95% CI 1.03-1.16, P=0.004). After the 2 years follow-up, rates of all-cause death (4.1% (19/465) vs. 0.3% (4/1 198) , P<0.001), cardiac death (2.6% (12/465) vs. 0.2% (2/1 198) , P< 0.001) and stent thrombosis (1.7% (8/465) vs. 0.5% (6/1 198) , P=0.015) were all significantly higher in high TRI group than in low TRI group. Multivariate Cox regression analyses showed that TRI≥ 23.05 was an independent risk factor of all-cause death (HR=5.22, 95%CI 1.63-16.72, P=0.005), cardiac death (HR=8.48, 95%CI 1.75-41.07, P=0.008) and stent thrombosis(HR=3.87, 95%CI 1.32-11.41, P=0.014) at 2 years after PCI in AMI patients, but which was not the independent risk factor of major adverse cardiovascular and cerebrovascular events (HR=0.96, 95%CI 0.69-1.36, P=0.834) .The area under ROC curve of TRI ≥ 23.05 on predicting 2 years all-cause mortality in AMI patients undergoing PCI was 0.803(95%CI 0.711-0.894, P<0.001). Conclusions: TRI is independently associated with SYNTAX score ≥ 33. TRI is also an independent risk factor of 2 years all-cause death, cardiac death and stent thrombosis in AMI patients undergoing PCI.

Abstract
OBJECTIVE To compare the surface microstructures and cyclic fatigue resistance of HyFlex EDM with HyFlex CM and HyFlex NT. METHODS Twelve 25 mm-long 25#/- HyFlex EDM and twelve 25 mm-long 25#/0.06 taper HyFlex CM or HyFlex NT were selected. The surface microstructure of the 2 instruments which were randomly selected from each group was observed by using scanning electron microscope (SEM). The remaining 10 instruments from each group were submitted to the cyclic fatigue test by using a simulated stainless steel root canal with 60° angle of curvature and curvature radius of 3.5 mm. The time till fracture was recorded, the number of cyclic fatigue (NCF) was calculated, the length of fracture fragment was evaluated, and the topographic features were analyzed by using SEM. The data were analyzed by using one-way analysis via SPSS 23.0 software. The statistical significance level was set at 0.05. RESULTS SEM observation of the surface and microstructural characterization revealed peculiar melting appearance and evenly distributed micropores on the surface of HyFlex EDM while observations of the surface of both HyFlex CM and HyFlex NT demonstrated machining grooves and irregularities. The NCF of HyFlex EDM was 838±223, which was significantly higher than not only that of HyFlex CM (582±99), but also that of HyFlex NT (81±20) (P<0.05), and the difference between the latter two groups was significant, as well (P<0.05). The length of fractured fragments of HyFlex EDM was (7.27±0.28) mm, which was significantly longer than the HyFlex CM and HyFlex NT, with values of (6.72±0.26) mm and (6.62±0.37) mm, respectively (P<0.05). Topographic features demonstrated typical cyclic fatigue for all the three groups while the region of crack origins was more for HyFlex EDM and HyFlex CM than that of HyFlex NT. As far as the dimple area was concerned, that of HyFlex EDM was deeper and larger than that of HyFlex CM and HyFlex NT. CONCLUSION Within the limitations of this study, electro-discharge machining leads to peculiar melting appearance with micropores instead of machining grooves and irregularities on the surface of HyFlex EDM, which may be the reason why HyFlex EDM exhibits significantly better cyclicfatigue resistance than HyFlex CM and HyFlex NT.

Abstract
OBJECTIVE To compare the effects of autoclave on surface microstructure and cyclic fatigue resistance of K3XF and K3. METHODS Forty-eight size 25, 0.06 taper 25 mm-long K3XF or K3 were randomly divided into 4 groups (n=12). The instruments from group 1 were not autoclaved, and the groups 2 to 4 underwent autoclave for 10 cycles, 20 cycles, and 30 cycles, respectively. The surface microstructure of two instruments randomly selected from each group was observed using scanning electron microscope (SEM). The remaining 10 instruments were submitted to the cyclic fatigue test by using a simulated metal root canal with curvature of 60° and radius 3.5 mm. The time till fracture was recorded, the number of cyclic fatigue (NCF) calculated, the fragment length evaluated, and the topographic features were analyzed using SEM. The data were analyzed using the two-way ANOVA analysis by SAS 9.3 software at a significance level of P<0.05. RESULTS SEM observation identified rough features on the surface of K3XF with micropores existing evenly. K3 was characterized by machining grooves, which located specifically in the flute, leaving a smooth cutting edge. After autoclave, SEM observation indicated that the micropores in the surface of K3XF became larger and more, whereas the machining grooves in the surface of K3 were squeezed, out of shape and flaking. As far as the NCF was concerned, new K3XF was 210±59, and no significant difference was found after 10, 20, and 30 cycles of autoclave for K3XF, values being 178±37, 208±48, and 227±43, respectively (P>0.05). For K3, the new one was 145±38, and no significant difference in NCF was demonstrated after 10 and 20 cycles of autoclave, with the values of 128±43 and 124±46, respectively (P>0.05). However, after 30 cycles of autoclave of K3, significant increase to 216±38 was identified (P<0.05). Topographic features demonstrated typical cyclic fatigue for all the groups. CONCLUSION The surface roughness of K3XF was increased after autoclave, while the cyclic resistance remained stable after up to 30 cycles.

Abstract
OBJECTIVES To estimate lung volume in normal population by a combination of multi-slice spiral CT and Pulmo software. METHODS Scans of the lung were performed on 45 normal individuals using Emotion 16-slice spiral CT and Pulmo software. A measurement instrument of work station was used to measure the vertical diameter of left and right lungs, the maximum anteroposterior and transverse diameters at the layers of apex pulmonis 1 cm below, arcus aortae, subcarinal and diaphragmatic dome, and the lung volume. Regression analysis was performed on normal lung volume and each measured parameter by SPSS 20.0 and an optimal model was selected. RESULTS The goodness of fit between the best curvilinear equations of the normal bilateral lung volumes was 0.981. The goodness of fit between the curvilinear equations of the normal bilateral lung volume and the product of the vertical diameter and the maximum transverse diameter of diaphragmatic dome were 0.977 and 0.972, respectively. Fifteen cases were selected to make a retrospective test on the 3 models. No significant difference was found between the estimated and measured with Pulmo software lung volumes. CONCLUSIONS The normal lung volume before injury can be estimated by the curvilinear equations established in this study. The percentage of lung compression can be measured based on the volume of compressed lung, which can provide a reference for the identification of lung compression degree.

Abstract
Objective: To compare the phase transformation behavior, bending property and cyclic fatigue resistance of CM-wire, R-phase and M-wire nickel-titanium endodontic files treated by 3 heat treatment techniques. Methods: Hyflex CM (25 mm, 25#/0.06) made from CM wire, TF (25 mm, 25#/0.06) made from R-phase heat treatment, ProTaper Next X2 (25 mm, tip size 25#/0.06) made from M-wire, Mtwo (25 mm, 25#/0.06) and ProTaper F2 (25 mm, tip size 25#/0.08) made from conventional nickel-titanium wire were chosen. Five of each files were chosen for differential scanning calorimetric (DSC) evaluation (n=5). The specimens were prepared from adjacent portions of the shaft. The weight and length were typically (20±1) mg and 2-3 mm. Another eight of the 5 nickel-titanium files were undergone cantilever-bending test, respectively (n=8). Further ten of the 5 instruments were submitted to the cyclic fatigue test by using a simulated metal root canal (n=10). The data of M(s), M(f), A(s), A(f), ΔH, bending load, number of cyclic fatigue (NCF), fragment length were analyzed using one-way analysis of variance at a significance level of P<0.05. Results: The A(f) of Hyflex CM [(60.27±0.94) ℃] and ProTaper Next [(51.40±0.32) ℃] were higher than body temperature of 37 ℃. The bending load values at 3.0 mm deflection of Hyflex CM [(0.867±0.074) N], TF [(1.275±0.146) N], Mtwo [(2.281±0.426) N], ProTaper Next [(3.104±0.252) N] and ProTaper [(4.227±0.483) N] increased gradually and significantly. The NCF of Hyflex CM (582±99), TF (427±85), ProTaper Next (158±22), Mtwo (129±32) and ProTaper (65±20) decreased gradually. Conclusions: The 3 heat treatment techniques exert tremendous influence on the phase transformation behavior and mechanical characteristics of the files, which demonstrate improved bending property and cyclic fatigue resistance than the conventional ones.

Abstract
Objective: To investigate the impact of aortic root morphology on the implantation depth of aortic valve prosthesis during trans-catheter aortic valve replacement (TAVR) in bicuspid aortic valve patients. Methods: Clinical data of 40 patients with native bicuspid aortic valve stenosis who underwent TAVR using the self-expandable prosthesis (the Venus A-valve) from 2014 to 2017 in Fuwai Hospital was retrospectively analyzed. The patients were divided into non-deep implantation group (implant depth ≤10 mm by instant angiogram after implantation,29 cases) and deep implantation group (implant depth> 10 mm by instant angiogram after implantation,11 cases).Pre-procedural aortic root characteristics (e.g. calcification, angle and dimensions) were assessed by CT. The impact of aortic root morphology on the implantation depth and clinical outcomes were also evaluated. Results: The age was (75.1±5.9) years with equal representation from the raphe-type and non-raphe type (52.5%(21/40) and 47.5%(19/40)).The bigger aorta angle ((56.5±4.5)° vs. (47.4±9.4)°, P=0.004),more frequent mild-calcification (HU850, <200 mm(3)) or severe-calcification(HU850, >1 000 mm(3)) of aortic leaflets (7/11 vs. 4/29, P=0.006), as well as higher ratio of left ventricular outflow tract perimeter to annulus perimeter ((109.2±7.5)% vs. (101.5±6.5)%, P=0.004) were found in the deep implantation group compared to the non-deep implantation group. The new in-hospital onset of bundle-branchheart-block or atrioventricular block conduction disturbance rate was higher in the deep implantation group than in the non-deep implantation group (6/11 vs. 2/29, P=0.030).Left ventricular ejection fraction was similar between deep implantation group and non-deep implantation group at baseline((49.9±8.9)% vs. (55.8±10.4)%, P=0.117), and was significantly lower in the deep implantation group than in the non-deep implantation group at 30 days after implantation ((51.6±12.8)% vs. (60.9±8.1)%, P=0.020). Conclusion: Aortic root morphology of bicuspid aortic valve patients is associated with implantation depth of the prosthesis during TAVR, which affects the conduction system and left ventricular function during and post TAVR.

Abstract
BACKGROUND Tacrolimus is used off-label in the treatment of Henoch-Schönlein purpura nephritis (HSPN) in children, with limited evidence-based data. Based on clinical empirical experience and mechanism of action, tacrolimus might be promoted as treatment for childhood HSPN. The objectives of this pilot study were to assess its effectiveness and safety, and to explore the potential impact of CYP3A5 genotype. METHODS Children with HSPN receiving tacrolimus as empirical treatment were included in this prospective, observational study. Effectiveness was classified as complete remission, partial remission or non-response. General safety data analyses during and after study drug exposure included adverse events, reasons for discontinuation, deaths, laboratory data and vital signs. Trough concentration was determined using high-performance liquid chromatography with tandem mass spectrometry. Pharmacogenetic analysis was performed on the CYP3A5 gene. RESULTS A total of 20 patients with a mean age of 7.5 (SD 2.1) years participated in the whole process of the study. Twelve patients reached complete remission and eight patients reached partial remission at the end of 6-month treatment. No patients discontinued tacrolimus treatment due to adverse events, and no drug-related adverse events were shown to have a causal association with tacrolimus therapy. Dose-adjusted trough concentration was significantly higher in children with CYP3A5*1 allele as compared with patients with CYP3A5*3/*3 genotype (170.7±100.9 vs 79.8±47.4 (ng/mL)/(mg/kg)). CONCLUSION This pilot study showed that tacrolimus might be an effective and well-tolerated drug for the treatment of HSPN in children. CYP3A5 polymorphism had a significant impact on tacrolimus concentration.

Abstract
Objective: This study sought to evaluate the safety and efficacy of FIREHAWK, a novel abluminal groove-filled biodegradable polymer sirolimus-eluting stent (SES) in patients with moderate-complex coronary lesions (including patients with small vessel disease, long lesion and multi vessel disease), and to validate the ability of the SYNTAX score (SS) to predict clinical outcomes in patients treated with FIREHAWK stent. Methods: TARGETⅡ was a prospective, multicenter, single-arm clinical trial, a total of 730 patients who underwent percutaneous coronary intervention (PCI) of de novo lesions in native coronary arteries in 24 medical centers in China from August 2011 to February 2012 were enrolled in this study. All patients were exclusively treated with the FIREHAWK stent. Clinical data including patients with diabetes, small vessel disease, long lesion and multi vessel disease were analyzed. The primary composite endpoint was the target lesion failure (TLF) of cardiac death, target vessel-related myocardial infarction (TV-MI), or target lesion revascularization (TLR). The secondary composite endpoint was patient-oriented endpoint (PoCE), a composite of all death, all myocardial in farction (MI), or any repeat revascularization; definite/probable stent thrombosis (ST) (including acute, late, and very late thrombosis) . SS was calculated in lesions with stenosis more than 50% with coronary artery diameter greater than 1.5 mm. Patients were grouped by tertiles of SS (≤7, >7 to ≤12, >12). Follow-up was performed up to 5 years. Results: A total of 730 patients were enrolled in the TARGET Ⅱ trial. The average SS was 10.9±6.9. 683 (93.6%) patients completed 5-year clinical follow-up. The 5-year incidence of TLF was 8.5%(58/683). The incidence of TLF components was as follows: cardiac death 2.0%(14/683), TV-MI 4.4%(30/683), TLR 3.4%(23/683). The incidence of PoCE was 16.4%(112/683). The incidence of definite/probable stent thrombosis was 0.7%(5/683).Multivariable Cox regression analysis showed that the diabetes subgroup (HR=1.123, 95%CI 0.623-2.026, P=0.699), the small vessel disease subgroup (HR=0.909, 95%CI 0.526-1.570, P=0.732), the long lesion subgroup (HR=1.561, 95%CI 0.922-2.640, P=0.097), and the multi vessel disease subgroup (HR=1.062, 95%CI 0.611-1.846, P=0.830) did not increase the HR of TLF compared with the counterpart subgroups. Multivariable Cox regression analysis showed that the hazard of TLF was not increased in the middle and high SS groups as compared with the low SS group (HR=1.203,95%CI 0.607-2.385,P=0.597;HR=1.548,95%CI 0.829-2.892,P=0.171). Conclusions: The 5 years follow-up results of TARGET Ⅱ trial shows that the biodegradable polymer of FIREHAWK stents have long-lasting safety and efficacy for patients with moderate-complex coronary lesions. SS is not the predicting factor for the occurrence of TLF in FIREHAWK treated patients with moderate-complex coronary lesions. Trial Registration Clinical Trials.gov, NCT0141264.

Abstract
Objective: To investigate the association between high-sensitivity C-reactive protein (hs-CRP) and long-term outcomes in Chinese patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) after drug-eluting stent (DES) implantation. Methods: A total of 4 815 consecutive NSTE-ACS patients who treated with DESs were included.Patients were divided into three groups: <1.00 mg/L, 1.00 to 2.99 mg/L and ≥3.00 mg/L, based on the level of hs-CRP on admission.Major adverse cardiovascular and cerebrovascular events (MACCE, including all-cause death, myocardial infarction, revascularization, in-stent thrombosis and stroke) were compared among groups during 2-year follow-up. Results: Patients with higher hs-CRP had more risk factors of cardiovascular events such as concomitant morbidities and multi-vessel lesions(68.5% vs 73.6% vs 76.2%, P<0.001). Higher hs-CRP value was associated with increased rates of MACCE (8.8% vs 11.2% vs 12.6%, P=0.003) and revascularization (6.5% vs 8.5% vs 9.8%, P=0.003). However, the rates of all-cause death, myocardial infarction, stroke, and stent thrombosis were comparable among groups(all P>0.05). Ongoing divergences in MACCE and revascularization among three groups were significant on Kaplan-Meier curves (both Log-rank P=0.003). Multivariable Cox regression analysis indicated that compared to hs-CRP<1.00 mg/L group, MACCE in the >3.00 mg/L group was increased by 42% [HR 1.42 (1.13-1.78), P=0.002]. Meanwhile, multivessel leisions, ejection fraction<50%, elevated white blood cell counts were also independent risk factors.CRP≥3.00 mg/L(HR 1.56, 95%CI 1.16-2.08, P=0.003, compared to <1.00 mg/L) and multivessel leisions were independent predictors of revascularization. Conclusions: (1)Patients with higher hs-CRP on admission have more risk factors of cardiovascular events.(2)Higher hs-CRP value is associated with increased rates of MACCE and revascularization.(3)Pre-procedural hs-CRP is an independent predictor of 2-year outcomes for Chinese NSTE-ACS patients treated with DESs.

Abstract
Objective: To quantify the extent and complexity of residual coronary stenosis following PCI by the residual SYNTAX score, and to evaluate its impact on adverse ischemic outcomes in acute coronary syndrome(ACS) patients. Methods: From January 2013 to December 2013, a total of 1 414 consecutive moderate- and high-risk ACS patients who underwent any PCI with multi-vessel coronary artery disease were evaluated.Patients were stratified by rSS quartiles and their outcomes were compared. Results: The rSS was 4.8±6.7. 591 patients (41.8%) had rSS=0(CR), 233 patients (16.5%) had rSS>0 but ≤ 3, 296 patients (20.9%) had rSS>3 but ≤8 and 294 patients (20.8%) had rSS>8.Clinical risk factors were more frequent in patients with incomplete revascularization(IR) compared with complete revascularization(CR). The 2-year rates of all-caused death(1.2% vs 0.4%, 2.0%, 4.4%, P=0.003), cardiac death, revascularization and MACCE were significantly higher in high rSS group, compared to other groups.By multivariable analysis, rSS was a strong independent predictor of ischemic outcomes at 2-year, including all-cause mortality (HR=1.05, 95%CI 1.01-1.09, P=0.019), cardiac death, revascularization and MACCE. Conclusions: The rSS is a strong independent predictor of all-caused death, cardiac death, revascularization and MACCE and has moderated predictive ability for those ischemic outcomes.

Abstract
Objective: To investigate the impact of direct bilirubin on long-term prognosis of acute coronary syndrome (ACS) patients post percutaneous coronary intervention(PCI). Methods: As a prospective and observational cohort study, a total of 6 431 consecutive ACS patients underwent PCI from January to December 2013 in Fuwai hospital were included. Patients were divided into 3 groups according to tertiles values of direct bilirubin as follows: low direct bilirubin group(<2.2 μmol/L, n=2 219), moderate direct bilirubin group(2.2-3.0 μmol/L, n=2 016), and high direct bilirubin group(>3 μmol/L, n=2 196). The clinical characteristics were compared among the 3 groups, and the impact of direct bilirubin on clinical adverse events (main adverse cardiovascular and cerebrovascular events included cardiogenic death, myocardial infarction, revascularization, stroke, and stent thrombosis) were analyzed at 2 years after PCI. Results: (1) Percent of male patients was 66.5%(1 475/2 219), 78.0%(1 572/2 016), and 86.2%(1 892/2 196), body mass index was(25.7±3.1), (26.0±3.3),and (26.0±3.2) kg/m(2), the ratio of the history of old myocardial infarction was 11.9%(264/2 219), 13.0%(263/2 016),and 14.9%(328/2 196), the ratio of the current smoker was 56.3%(1 249/2 219), 59.1%(1 192/2 016),and 60.0%(1 317/2 196) in low, moderate and high direct bilirubin groups respectively, and the differences were statistically significant (P<0.01 or 0.05). (2) Two years after PCI, the all-cause mortality was 0.8%(17/2 219), 1.8%(36/2 016), and 1.5%(33/2 196) (P=0.011),the cardiogenic mortality was 0.5%(12/2 219), 1.3%(26/2 016), and 0.6%(13/2 196) (P=0.010),the ratio of myocardial infarction was 2.2%(49/2 219), 2.4%(49/2 016), and 1.4%(31/2 196)(P=0.044),the ratio of revascularization was 8.8%(195/2 219), 8.3%(168/2 016),and 8.9%(196/2 196)(P=0.783),the ratio of stroke was 1.4%(30/2 219),1.1%(22/2 016), and 1.9%(42/2 196)(P=0.076),the ratio of stent thrombosis was 0.9%(19/2 219), 1.2%(24/2 016),and 0.7%(15/2 196)(P=0.210) in low, moderate and high direct bilirubin groups, respectively. (3) Multivariable Cox regression analysis showed that, patients in moderate direct bilirubin group faced increased the risk of all-cause mortality compared with patients in the low direct bilirubin group (HR=2.23, 95%CI 1.23-4.05, P= 0.009), and the risk of all-cause mortality was similar between high direct bilirubin group and low direct bilirubin group (HR=1.84, 95%CI 0.99-3.38, P= 0.051). There were no statistically significant difference in the risks of main adverse cardiovascular and cerebrovascular events,cardiogenic death, myocardial infarction, revascularization, stroke, and stent thrombosis in moderate and high direct bilirubin groups compared with low direct bilirubin group (all P>0.05). Conclusion: Moderate direct bilirubin level is associated with increased risk of all-cause death at 2 years after PCI compared with low level of direct bilirubin group.

Abstract
Objective: To explore the current prevalence of dyslipidemia in adult population of 9 provinces of China and the epidemic characteristics of this disease. The potential influence of social economic development on dyslipidemia was also observed. Methods: Present research data are derived from the result of the investigation about survey on health and nutrition in China in 2011, in which multistage stratified cluster random sampling method was adopted to investigate the 24 345 individuals in 216 communities from 9 provinces in China and 10 242 blood samples were collected. In this research, 8 669 blood samples of people over 18 years old were selected for final analysis. After adjustment of age, the percentage of dyslipidemia patients in Chinese adults was calculated. Results: The percentage of dyslipidemia in Chinese adults is 39.91% (3 460/8 669). The percentage of dyslipidemia at the age of 18-24, 35-44, 45-59 and over 60 years old were 30.25% (373/1 233),37.19% (774/2 081), 44.22% (1 304/2 949) and 41.94%(1 009/2 406),respectively (χ(2)=333.02, P<0.01); the percentage of dyslipidemia in male and female population was 51.11% (1 956/3 827) and 31.06%(1 504/4 842), respectively (χ(2)=60.35, P<0.01); the percentage of dyslipidemia in urban residents and rural residents was 42.56% (1 144/2 687) and 38.72%(2 316/5 982), respectively (χ(2)=11.72, P<0.01);the percentage of dyslipidemia in high-GDP regions and low-GDP regions was 43.04% (1 567/3 641) and 37.65% (1 893/5 028), respectively (χ(2)=25.57, P<0.01) .The prevalence of adult hypercholesterolemia in Chinese adult is 9.01% (781/8 669), the prevalence of borderline increased cholesterol is 22.54% (1 954/8 669), the prevalence of hypertriglyceridemia is 27.02% (2 342/8 669), the prevalence of lower high-density lipoproteinemia is 14.36% (1 245/8 669) and the prevalence of increased low-density lipoproteinemia was 10.23% (887/8 669). All prevalence rates are significantly higher compared to the 2005 survey results. Conclusion: The prevalence of dyslipidemia in Chinese adults is high and the prevalence increases in a fast pace. The current situation of dyslipidemia in Chinese adults is critical and targeted strategies should be applied to control the dyslipidemia in adult Chinese population.

Abstract
Objective: To evaluate the prognostic value of Global Registry of Acute Coronary Events(GRACE) discharge score for long-term out-of-hospital death in acute coronary syndrome (ACS) after drug-eluting stents (DES) and with Dual-antiplatelet Therapy (DAPT). Methods: Our study was a prospective, observational, single center (Fuwai Hospital of China) study.A total of 6 431consecutive ACS patients underwent percutaneous coronary intervention(PCI)between January 2013 and December 2013 were involved.The primary endpoint was all-cause death and second endpoint was major adverse cardiovascular and cerebrovascular events (MACCE) as a composite of all-cause death, myocardial infarction, revascularization, stent thrombosis or stroke. Results: Finally, 5 867 ACS patients who were received DES with DAPT and had no in-hospital event included in this study, and 59 (1.01%) death and 608 (10.36%) MACCE were reported during 2-year follow-up after discharge.GRACE score was significantly higher among death patients than those survivalpatients (94± 28 vs 78± 24, P<0.001). According to risk stratification of GRACE discharge score, as compared to the low-risk group, death risk in high-risk group was 6.73 times (HR=6.73, 95%CI 3.53-12.84; P<0.001) higher, but could not distinguish between the moderate and low risk group (HR=1.61, 95%CI 0.88-2.95; P=0.124). The GRACE score showed predictive value in ACS patients after DESand with DAPT (area under the receiver operating characteristic curve (AUROC)=0.661; 95%CI 0.586-0.736, P<0.001). In subgroup analysis, GRACE score also showed predictive value both in unstable angina pectoris (UAP)(AUROC=0.660, 95%CI 0.576-0.744; P<0.001) and acute myocardial infarction(AMI)subgroup (AUROC=0.748, 95%CI 0.631-0.864; P=0.001). Conclusion: GRACE discharge score shows prognostic value for long-term out-of-hospital death in ACS patients undergoing PCI with DES and DAPT, and demonstrates good risk stratification of high and low-risk of death.

Abstract
Objective: To investigate the clinical features of Takayasu's arteritis (TAK) with glomerulonephropathy and to improve physicians' understanding of this complication in patients with TAK. Methods: Clinical data were retrospectively collected including manifestations, laboratory tests, image findings and treatment of 8 patients diagnosed as Takayasu's arteritis with glomerulonephropathy from January 2002 to January 2017 in Peking Union Medical College Hospital. Results: Glomerulonephropathy was confirmed based on percutaneous renal biopsy. There were 6 women and 2 men. The median onset age and median disease duration were 24 (18-37) years and 42 (3-360) months, respectively. Five patients had hypertension. The 24 hour urinary protein was 0.18-14.91 g. Red blood cells and casts in urine were tested among 4 and 2 patients, respectively. Three patients had renal artery stenosis. Three patients demonstrated mesangial proliferative glomerulonephritis, two with IgA nephropathy, two with minimal change disease and one with membranoproliferative glomerulonephritis. Seven patients received glucocorticoid combined with cyclophosphamide therapy (glucocorticoid 40-60 mg/d, prednisone or equivalent; cyclophosphamide 0.4 g/week iv. or cyclophosphamide 0.1 g/d po.). Uninary blood cells removed and 24 hour urinary protein decreased from 1.65 g to 0.90 g after treatment for 12 months in one patient. The other 7 patients were missing. Conclusion: Glomerulonephropathy is occasionally observed among TAK patients. Mesangial proliferative glomerulonephritis is the most common pathological subtype. Glucocorticoid combined with cyclophosphamide therapy could be an optional therapy for Takayasu's arteritis with glomerulonephropathy.

Abstract
Objective: To understand the epidemiological characteristics of Human coronavirus (HCoV), the patterns of emergence and circulation, and the genotype distribution of human coronavirus OC43 (HCoV-OC43) from November, 2009 to April, 2016 in Shanghai. Methods: A total of 6 059 respiratory specimens, including pharyngeal swab, sputum, nasopharyngeal aspirates and alveolar lavage fluid, as well as relative clinical data were collected from patients with acute respiratory infections from seven sentinel hospitals during November, 2009 to April, 2016 in Shanghai. Respiratory specimens were tested by RT-PCR with HCoV-conserved primers and subsequently genotyped by DNA sequencing. Using specific primers to amplify and sequence full-length Spike (S), RNA-dependent RNA polymerase (RDRP) and nucleocapsid (N) gene from HCoV-OC43 positive samples. Further genotype and phylogenetic analysis of HCoV-OC43 were performed by conducting phylogenetic trees. Results: Among 6 059 patients, the total frequency of HCoV was 63 (1.04%), in which HCoV-OC43 was the most frequently detected species with 34 positive samples, followed by human coronavirus 229E (HCoV-229E) and human coronavirus HKU1 (HCoV-HKU1) with 18 and 10 positive sample respectively. However, other HCoV like human coronavirus NL63 (HCoV-NL63), severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle-East Respiratory Syndrome Coronavirus (MERS-CoV), were not been detected, which illustrated that HCoV-OC43 was the dominant subtype. The full-length of S, RDRP and N gene were obtained from 29 HCoV-OC43 positive samples. According to the sequence-analysis, 27 of which was genotype D, 2 of which was genotype B and others genotype, including genotype E, F and G, were not detected. The result indicated that the genotype D may be the dominant genotype. Further analysis of S protein that help HCoV-OC43 to entry host cell and stimulate the host immune system to produce neutralizing antibody found that two important functional domains in S protein, N-terminal domain (NTD) and receptor-binding domain (RBD) contained more amino acid substitution and positive selection sites, accompanied with amino acid insertion/deletion. 13 positive selection sites were all located in the NTD or RBD, 10 of which were located in the NTD and 3 in the RBD. Conclusion: Human coronavirus OC43 was the major circulation human coronaviurs in Shanghai from 2009 to 2016, in which genotype D was the dominant genotype. NTD and RBD regions of the S protein were hypervariable region during HCoV-OC43 evolution, and had amino acid substitutions as well as amino acid insertion/deletion.

Abstract
Objective: To investigate the in-hospital and long-term outcomes of patients with left ventricular ejection fraction (LVEF) <50% undergoing percutaneous coronary intervention (PCI) . Methods: From January to December 2013, 10 445 consecutive patients who underwent PCI in Fuwai Hospital and the LVEF value was available were prospectively included. The patients were divided into LVEF≥50% group (9 896 cases) and LVEF<50% group (549 cases) . The in-hospital and 2-year clinical outcomes were compared between the 2 groups. The association between LVEF<50% and clinical outcomes was assessed using multivariable Cox regression analysis. Results: (1) Compared with LVEF ≥50% group, LVEF< 50% group had higher rates of in-hospital all-cause death (1.1% (6/549) vs. 0.2% (17/9 896) , P<0.01) , cardiac death (1.1% (6/549) vs. 0.1% (12/9 896) , P<0.01) , in-stent thrombosis (0.7% (4/549) vs. 0.2% (18/9 896) , P<0.01) , myocardial infarction (2.4% (13/549) vs. 1.2% (121/9 896) , P<0.05) ,and major adverse cardiovascular and cerebrovascular events (MACCE) which including death, myocardial infarction, revascularization, in-stent thrombosis, and stroke (3.6% (20/549) vs. 1.4% (137/9 896) , P<0.01) . (2) A total of 10 388 (99.5%) patients completed 2-year follow-up. Compared with LVEF ≥50% group, LVEF<50% group had higher rates of 2-year all-cause death (4.7% (26/549) vs. 1.0% (101/9 896) , P<0.01) , cardiac death (4.0% (22/549) vs. 0.5% (50/9 896) , P<0.01) , in-stent thrombosis (3.1% (17/549) vs. 0.7% (71/9 896) , P<0.001) , myocardial infarction (4.2% (23/549) vs. 1.9% (186/9 896) , P<0.01) ,and MACCE (17.9% (98/549) vs. 11.8% (1 172/9 896) , P<0.01) . There were no significant differences on the rates of 2-year target-vessel revascularization, bleeding and stroke between the two groups. (3) The multivariable Cox regression analysis demonstrated that LVEF< 50% was the independent risk factor of 2-year all-cause death (HR=2.47, 95%CI 1.49-4.08, P<0.01) , cardiac death (HR=3.25, 95%CI 1.79-5.90, P<0.01) , in-stent thrombosis (HR=4.19, 95%CI 2.39-7.34, P<0.01) , myocardial infarction (HR=2.00, 95%CI 1.26-3.16, P<0.01) , and MACCE (HR=1.40, 95%CI 1.13-1.74, P<0.01) . (4) After propensity score matching, all in-hospital outcomes were similar between the two groups, including all-cause death, cardiac death, in-stent thrombosis, myocardial infarction, revascularization, bleeding, stroke, and MACCE (all P>0.05) . After propensity score matching,the multivariable Cox regression analysis demonstrated that LVEF<50% was still an independent risk factor of 2-year all-cause death (HR=3.08, 95%CI 1.37-6.89, P<0.01) , cardiac death (HR= 4.12, 95%CI 1.53-11.07, P<0.01) ,and in-stent thrombosis (HR=3.82, 95%CI 1.27-11.5, P<0.05) . Conclusion: LVEF< 50% is an independent risk factor of 2-year all-cause death, cardiac death, and in-stent thrombosis in patients undergoing PCI, but it does not increase the risk of target-vessel revascularization, bleeding or stroke.

Abstract
Objective: To investigate the clinical characteristics and prognosis in patients with stroke after percutaneous coronary intervention (PCI). Methods: From January 2013 to December 2013, 10 724 consecutive patients undergoing PCI including acute coronary syndrome and stable angina pectoris were enrolled.A two years' follow up was conducted among these patients to investigate the clinical characteristics and prognosis of patients with stroke and of those without. A comparison was done between the two groups. Results: One hundred and forty-five patients had stroke (1.4%) during the follow-up period after PCI, including 124 cases with ischemic stroke (1.2%), out of whom 4 (3.2%) patients died; 21 cases with hemorrhagic stroke, out of whom 9 patients (42.9%) died.There was more female, and more patients with risks factors, hypertension, previous myocardial infarction, previous stroke, etc. in the patients with stroke.During the 2-year follow-up, patients with stroke experienced higher incidence of all-cause mortality (9% vs 1.1%, P<0.000 1). There were no significant differences in the incidences of cardiac death, myocardial infarction, revascularization, stent thrombosis and major adverse cardiovascular event rates between the two groups.COX regression analysis showed that stroke after PCI was associated with the increased mortality (HR=8.387, 95%CI: 4.725-14.855, P<0.000 1). Meanwhile, after propensity score matched analyses (129 pairs), the trend was not changed, and stroke was still an independent risk factor of all-cause mortality (HR=6.737, 95%CI: 1.52-29.85, P=0.012). Conclusions: The patients underwent PCI, who had stroke later, had more clinical risk factors, and more serious degree of atherosclerosis.The incidence of stroke is an independent risk factor for all-cause mortality in patients with coronary heart disease after PCI.

Abstract
Objective: To evaluate the relationship between platelet distribution width(PDW) and the extent of coronary artery disease and 2-year outcome in patients received percutaneous coronary artery intervention(PCI) because of stable coronary artery disease(SCAD). Methods: We consecutively enrolled 4 293 patients who received PCI because of SCAD in Fuwai Hospital from Jan 2013 to Dec 2013, patients were followed up for 2 years. Patients were divided into three groups according to tertiles values of PDW as follows: PDW≤11.4%(1 402 patients), 11.4%<PDW≤12.9%(1 441 patients) and PDW>12.9% (1 450 patients). Major adverse cardiovascular and cerebrovascular events (MACCE) were defined as the occurrence of death, myocardial infarction, target vessel revascularization, intra stent thrombosis and stroke during follow-up. Multivariable logistic regression was used to evaluate the relationship between PDW and the extent of CAD. Multivariable Cox regression was used to evaluate the relationship between PDW and prognosis of SCAD patients. Results: PDW was associated with diabetes mellitus, body mass index, red cell distribution width, mean platelet volume (MPV), platelet counts and glycosylated haemoglobin (P<0.05), but not associated with age, sex, estimated glomerular filtration rate (P>0.05). PDW was not correlated with the extent of CAD(P=0.990), SYNTAX score(P=0.721), no-reflow phenomenon after PCI(P=0.978). Multivariable logistic regression also showed no relationship between PDW and extent of CAD (OR=0.994, 95%CI 0.961-1.029, P=0.73). PDW was found to be an independent risk factor of 2-year cardiac death (HR=1.242, 95%CI 1.031-1.497, P=0.022), but was not an independent risk factor of all-cause death and MACCE. Conclusions: PDW is not related with the extent of coronary artery disease. PDW is an independent risk factor of 2-year cardiac death, but is not an independent risk factor of all-cause death and MACCE in this patient cohort.
