Abstract
Periodontal disease is a chronic infectious disease characterized by gingival inflammation and progressive destruction of alveolar bone, and the interaction between plaque microbes and host defense affects the process of the disease. Recent studies have found that autophagy is one of the most primitive host defense responses against pathogenic microbial invasion. Autophagy plays an important role in the development of periodontal disease through such functions as clearing pathogens, regulating inflammatory responses and promoting osteoclast activation to affect bone resorption with inflammatory factors. This review article mainly introduces the research advances on autophagy mechanism and the relationship between autophagy and periodontal disease from the domestic and foreign literatures and expounds the mechanism of autophagy and periodontal pathogens, inflammatory reaction and bone resorption of osteoclasts, so as to enrich the pathogenesis of periodontal disease and provide a new perspective for the treatment of periodontal disease.

Abstract
AIMS We developed a strategy for localized delivery of the LFCA (lactoferricinlactoferrampin), which is actively synthesized in situ by Lactococcus lactis (pAMJ399-LFCA/LLMG1363), and explored the possibility of using pAMJ399-LFCA/LLMG1363 as an alternative additive diet to antibiotics. METHODS AND RESULTS The antimicrobial activities of the LFCA derived from pAMJ399-LFCA/LLMG1363 were tested in vitro. The results showed that LFCA had an inhibitory effect on Staphylococcus aureus, Escherichia coli and Salmonella enteritidis. Then, the pAMJ399-LFCA/LLMG1363 was used as an additive diet for piglets. Our data demonstrated that oral administration of pAMJ399-LFCA/LLMG1363 significantly improved the average daily gain, feed-to-gain ratio, intestinal mucosal integrity and decreased the serum endotoxin and d-lactic acid levels. The mRNA expression levels of intestinal tight junction proteins (including occludin, Claudin-1 and ZO-1) were significantly upregulated by pAMJ399-LFCA/LLMG1363 administration. The serum immunoglobulin G (IgG) levels, intestinal secretory immunoglobulin A (sIgA) levels, IL-2, IL-10 and TGF-β levels were significantly increased by pAMJ399-LFCA/LLMG1363. Furthermore, our data revealed that oral administration of pAMJ399-LFCA/LLMG1363 significantly increased the number of general Lactobacillus, and decreased the total viable E. coli counts in the ileum and cecum contents. CONCLUSIONS We developed a novel pAMJ399-LFCA/LLMG1363 secreting LFCA, which had probiotic effects on the growth performance, intestinal morphology, intestinal barrier function and immunological indices of weaned piglets. SIGNIFICANCE AND IMPACT OF THE STUDY pAMJ399-LFCA/LLMG1363, with probiotic effects on the health of weaned piglets, may be a promising feed additive for weaned piglets.

Abstract
AIMS The purpose of this study was to evaluate the biological fixation of a 3D printed porous implant, with and without different hydroxyapatite (HA) coatings, in a canine model. MATERIALS AND METHODS A canine transcortical model was used to evaluate the characteristics of bone ingrowth of Ti6Al4V cylindrical implants fabricated using laser rapid manufacturing (LRM). At four and 12 weeks post-implantation, we performed histological analysis and mechanical push-out testing on three groups of implants: a HA-free control (LRM), LRM with precipitated HA (LRM-PA), and LRM with plasma-sprayed HA (LRM-PSHA). RESULTS Substantial bone ingrowth was observed in all LRM implants, with and without HA, at both time periods. Bone ingrowth increased from 42% to 52% at four weeks, to 60% to 65% at 12 weeks. Mechanical tests indicated a minimum shear fixation strength of 20 MPa to 24 MPa at four weeks, and 34 MPa to 40 MPa at 12 weeks. There was no significant difference in the amount of bone ingrowth or in the shear strength between the three implant types at either time period. CONCLUSION At four and 12 weeks, the 3D printed porous implants exhibited consistent bone ingrowth and high mechanical shear strength. Based on the results of this study, we confirmed the suitability of this novel new additive manufacturing porous material for biological fixation by bone ingrowth.

Abstract
Objective: To evaluate the therapeutic efficacy and safety of immunosuppressive therapy (IST) combined with recombinant human thrombopoietin (rhTPO) for severe aplastic anemia (SAA) in pediatric patients. Method: A retrospective case-control study was conducted and the clinical data of 45 pediatric patients with de novo SAA admitted to the Anemia Diagnosis and Treatment Center of Chinese Academy of Medical Sciences & Blood Disease Hospital during the period from December 2009 to December 2014 were analyzed. Among them, 15 patients were treated with the regimen of IST together with rhTPO and 30 patients were given IST treatment only. The variation characteristics of the peripheral blood routine as well as the transfusion of blood products was dynamically observed, and the therapeutic efficacy was assessed respectively after 3, 6 and 12 months after the treatment. In the meantime, adverse effects related to rhTPO application were recorded. Thereafter, the statistics of the two groups were compared by non-parametric rank sum test. Result: Among 45 pediatric patients, there were 26 male and 19 female, and the median age was 11 years (6-14). The number of patients received good hematological response(complete remission (CR) plus good partial response (GPR)) in the combinatory group versus vs. the IST group was 6 vs. 3 patients (χ(2)=3.906, P=0.048) at the 3rd month, 7 vs. 7 patients (χ(2)=1.568, P=0.210) at the 6th month, and 13 vs. 14 patients (χ(2)=6.667, P=0.01) at the 12th month respectively. For those achieved good hematological response at the 3rd month, the amount of platelets transfusion and red blood cells transfusion of the combined group were both less than that of the IST group during the period from the 10th to the 12th weeks (platelets transfusion: 1.4 U vs. 2.9 U, t=-3.523, P=0.002; red blood cells transfusion: 0.8 U vs. 2.6 U, t=-2.392, P=0.026). No serious adverse effect related to rhTPO application was observed in the IST combined with rhTPO group. Conclusion: Application of rhTPO can improve the short-term therapeutic efficacy of IST for pediatric SAA, alleviate transfusion dependence, and has a good safety profile.

Abstract
Objective: To investigate the long-term prognosis of Second generation drug-eluting stents(G2-DES) in diabetic mellitus(DM) and non-DM patients. Methods: Patients with coronary heart disease(CHD) in Fuwai Hospital from January 2013 to December 2013 who had exclusively G2-DES implantation, were consecutively included the follow-up period was 2 years. Results: A total of 6 094 patients with CHD were implanted with G2-DES, of which 1 862 patients with DM, and 4 232 patients without DM.The proportion of DM patients receiving G2-DES implantation with the following characteristics: advanced age, female, hypertension, hyperlipidemia, history of previous stroke, history of peripheral artery disease, previous history of PCI, and with triple vessel, high preoperative Syntax score, high number of target lesions, B2 or C type lesions, severe calcification lesions, and chronic occlusive disease were significantly higher than those of non-DM patients(P<0.05). The incidence of major adverse cardiac and cerebral vascular events(MACCE), target vascular revascularization(TVR) and target lesion revascularization(TLR) were higher in DM patients than in non-DM patients during 2 year's follow-up(P<0.05). The univariate COX regression analysis showed that diabetes was risk factor for MACCE in patients with CHD implanting G2-DES(HR=1.241, 95%CI: 1.053-1.463, P=0.010). However, multivariable COX analysis showed that DM was not an independent risk factor for MACCE in CHD patients with G2-DES(HR=1.125, 95%CI: 0.952-1.330, P=0.167). While age, female, preoperative Syntex score, triple vessel, B2 or C lesion were independent risk factors for poor clinical prognosis in CHD patients with G2-DES. Conclusions: (1) CHD patients with DM often accompany more clinical risk factors and complicated coronary lesions; (2) the incidence of MACCE, TVR and TLR in DM patients is significantly higher than non-DM patients with G2-DES during the 2 year's follow-up; (3) after multivariate adjustment, DM is not an independent risk factor for poor clinical prognosis in CHD patients with G2-DES, while traditional risk factors and complex coronary lesions are independent risk factors for poor clinical prognosis.

Abstract
AIM To evaluate the clinical usefulness of quantitative dual-energy (DE) computed tomography (CT) iodine enhancement metrics combined with morphological CT features in distinguishing small-cell lung cancer (SCLC) from non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS One hundred and six untreated lung cancer patients who underwent DECT before biopsy or surgery were prospectively enrolled. Twenty-seven routine CT descriptors, including tumour location, size, shape, margin, enhancement heterogeneity, and internal and surrounding structures, and associated findings were assessed and DECT parameters were measured in all patients. Multiple logistic regression analyses were applied to identify independent predictors of SCLC. The area under the receiver operating characteristic curve was compared between CT features combined with DECT metrics and CT features alone for distinguishing SCLC from NSCLC. RESULTS Histology revealed NSCLC in 80 and SCLC in 26 patients. In univariate analysis, 12 morphological CT features and two DECT metrics differed significantly between NSCLC and SCLC. When DECT parameters were combined with CT features for multivariate analysis, the independent predictors of SCLC were large tumour size, central location, confluent mediastinal lymphadenopathy, homogeneous enhancement, absence of coarse spiculation, and lower iodine density and iodine ratio (all p<0.05). The area under the receiver operating characteristic curve was improved from 0.908 to 0.981 after adding DECT metrics compared with CT features alone (p=0.007). CONCLUSION The combination of DECT measures and CT morphological features can be used to distinguish SCLC from NSCLC, with higher diagnostic performance compared with CT morphological features alone.

Abstract
Objective: To investigate the impact of coronary lesion calcification on the long-term outcome of patients with coronary heart disease after percutaneous coronary intervention. Methods: In this prospective observational study, a total of 10 119 consecutive patients with coronary heart disease undergoing percutaneous coronary intervention from January 1 to December 31, 2 103 in our hospital were enrolled. The patients were divided into non/mild calcification group (8 268 cases) and moderate/severe calcification group (1 851 cases) according to the angiographic results. The primary endpoint was one-year major adverse cardiovascular events (MACE), including all-cause death, myocardial infarction, and target vessel revascularization. Results: The patients were (58.3±10.3) years old, and there were 2 355 females (23.3%). Compared with non/mild calcification group, patients in the moderate/severe calcification group were older ((60.0±10.6) years vs. (57.9±10.2) years, P<0.01), and had higher proportion of female (25.4% (470/1 851) vs. 22.8% (1 885/8 268), P=0.02), debates (33.9% (628/1 851) vs. 29.0% (2 399/8 268), P<0.01), hypertension (68.0% (1 259/1 851) vs. 63.7% (5 264/8 268), P<0.01), coronary artery bypass grafting (4.6% (85/1 851) vs. 3.2% (268/8 268), P<0.01), stroke (12.6% (233/1 851) vs. 10.4% (861/8 268), P=0.01), and renal dysfunction (6.2% (115/1 851) vs. 3.7% (303/8 268), P<0.01). Compared with non/mild calcification group, patients in themoderate/severe calcification group experienced longer procedure time (37 (24, 61) min vs. 27 (17,40) min, P<0.01) and stent length was longer (32 (23,48) mm vs. 27 (18,38) mm, P<0.01), and percent of rotational atherectomy was higher (2.56%(57/2 229) vs. 0.03% (3/11 930), P<0.01). One-year follow-up results showed that MACE (7.5% (139/1 846) vs. 4.9% (402/8 243), P<0.01), all-cause death (1.0% (19/1 846) vs. 0.6% (49/8 243), P=0.04), myocardial infarction (2.2% (41/1 846) vs. 1.4% (114/8 243), P=0.01), and target vessel revascularization (5.0% (92/1 846) vs. 3.2% (266/8 243), P<0.01) were all significantly higher in moderate/severe calcification group than in non/mild group. Multivariate Cox regression analysis showed that moderate/severe calcification was an independent predictor of MACE at one-year after the procedure (HR=1.41, 95%CI 1.16-1.72, P<0.01). Conclusion: Moderate/severe calcification in coronary lesion is an independent predictor of long-term poor prognosis in coronary heart disease patients undergoing percutaneous coronary intervention.

Abstract
OBJECTIVE Spontaneous paralysis from hourglass-like fascicular constriction of peripheral nerves is rare, its clinical manifestations are not well documented, and its pathogenesis remains unknown. The unclear origin of this disorder and difficulty in diagnosis result in its uncertain management. The authors sought to gain a more thorough understanding of this condition through describing the anatomy, clinical features, etiology, and treatment of hourglass-like constriction. METHODS The authors retrospectively reviewed 20 patients (22 nerves) with hourglass-like constriction. The patients' clinical information was reviewed. Preoperative sonographic assessment and electrophysiological examination of involved nerves were performed. Surgical treatments included interfascicular neurolysis and neurorrhaphy. Samples of tissue subjected to resected constriction were sent for pathological analysis. The patients had regular face-to-face follow-up visits. RESULTS Acute pain was always the first symptom and was followed by paralysis. Paralysis progression was rapid and serious. Surgical exploration indicated an hourglass-like constricted segment completely unrelated to the compressive structures. Electrophysiological analysis showed severe denervation, and histopathological examination showed inflammatory cell infiltration, demyelination, and reduction of nerve fibers. CONCLUSIONS Hourglass-like fascicular constrictive neuropathy has an integrative effect from multiple different mechanisms. Surgical intervention is beneficial for selected patients who do not recover in a timely fashion and have hourglass-like lesions confirmed by preoperative ultrasound imaging. The authors recommend that early surgical intervention of the nerve be offered to patients who do not show any signs of recovery 3 months after onset. Both interfascicular neurolysis and neurorrhaphy are effective treatment methods. Mild to moderate constriction can usually be treated successfully by interfascicular neurolysis alone, whereas more advanced lesions with loss of fascicle continuity (severe constriction) may be best treated with resection and direct neurorrhaphy.

Abstract
OBJECTIVE Diabetes is a common chronic disease. ARF is a new tumor suppressor, which is one hotspot of cell cycle regulators. The mutation of ARF is absent in nearly 50% of tumors. ARF plays an important role in many physiological processes, such as cell proliferation, cell senescence and cell cycle arrest. However, the molecular mechanism of ARF regulating is not clear at present. Our study aims to explore the mechanism of ARF in diabetes. METHODS ARF-Tg mice and C57 mice were fasted for 12 hours before the experiment. STZ was injected at a dose of 45-65 mg/kg. The model was established for blood glucose ≥16.7 mmol/L, the level of sugar in urine was at 3 + -4+. The experiment was carried out when the mice was eight weeks. The levels of glucagon with or without doxycycline mice, the proliferation and apoptosis of β-cell after immunosuppressive therapy were determined by immunofluorescence assay. Immunofluorescence and immunohistochemistry were used to observe the changes of insulin and glucagon. RESULTS Forty-eight model mice (96%) were divided into two groups, each group has 24 mice, respectively. There was not significant difference of insulin and glucagon in both groups without induction. After induction, the level of insulin was increased in ARF-Tg mice, the neonatal β cells were not increased but the number of proliferation cells and apoptotic cells was increased. Sirolimus combined with tacrolimus can effectively inhibit the reversal of the development of diabetes, but the conclusions need to be further confirmed in clinical. CONCLUSIONS High expression of ARF can promote the occurrence of diabetes by accelerating cell proliferation and apoptosis. Immunosuppressive agents can effectively reverse this phenomenon.

Abstract
OBJECTIVE To prepare ion exchange doxorubicin-loaded poly (acrylic acid) microspheres (DPMs) and evaluate the properties of these chemoembolic agents. METHODS Poly (acrylic acid) microspheres (PMs) without drug were prepared by inverse suspension polymerization method and then doxorubicin was loaded by ion exchange mechanism to prepare DPMs. Optical microscope was used to investigate the morphology and particle size distribution of PMs and DPMs; fluorescence microscope and confocal microscope were used to observe the distribution of doxorubicin after drug loading. Elasticities of both the microspheres were evaluated by texture analyzer. High performance liquid chromatography (HPLC) method was established to determine the drug loading behavior of PMs and releasing behavior of DPMs. The in vivo embolic property was evaluated by embolizing the hepatic artery of a rabbit with 0.1 mL of DPMs. RESULTS PMs and DPMs were both spherical in shape, smooth in surface and dispersed well. Doxorubicin was mainly in the outer area inside of DPMs and distributed evenly. The average particle size of PMs and DPMs were (283±136) μm and (248±149) μm, respectively. PMs and DPMs both had good compression ability with the Young's modulus of (62.63±1.65) kPa and (93.94±1.10) kPa separately. PMs reached the drug loading balance at 12 h, and the entrapment efficiency was greater than 99%. Drug loading of PMs in doxorubicin solution at the concentration of 5.0 g/L and 12.5 g/L was (19.78±0.27) g/L and (49.45±0.37) g/L, respectively. Doxorubicin released slowly from DPMs in PBS and the accumulative release percentages of DPMs with corresponding drug loading were 6.82%±0.02% and 2.83%±0.10% after 24 h, respectively. Arterial angiograms showed that the hepatic artery of the rabbit was successfully embolized with DPMs. CONCLUSION DPMs with good performance of loading doxorubicin could be a potential embolic agent for transcatheter arterial chemoembolization.

Abstract
Objective: To investigate the effect of heterogeneous nuclear ribonucleoprotein K (hnRNP K) and its interaction with human papillomavirus 16 (HPV16) on cervical intraepithelial neoplasia (CIN). Methods: The participants included 67 women with normal cervix (NC), 69 women with CINⅠ and 68 women with CINⅡ/Ⅲ in a community cohort of pathologically diagnosed women established in Jiexiu of Shanxi province, from June 2014 to June 2015. A structured questionnaire was used to collect the demographic data of the subjects and the related factors of cervical lesions. Cervical exfoliated cells and cervical tissues from biopsy or surgery were selected. The infection status of HPV16 was detected by flow-through hybridization. The protein expression levels of hnRNP K were evaluated by Western blot. SPSS 23.0 software was used to collate and analyze the data. To study the differences in demographic characteristics, related factors, hnRNP K protein and HPV16 infection among NC, CINⅠand CINⅡ/Ⅲgroups, χ(2) test, trend χ(2) test, and Kruskal-Wallis H test were conducted. Multiple comparisons of hnRNP K protein in three groups were completed by using the Bonferroni method. The OR and its 95%CI of hnRNP K, HPV16 and CIN were calculated by using the unconditional logistic regression models. Two-way interactions between hnRNP K protein and HPV16 infection on CIN were analyzed by using additive model and related indicators. Results: HPV16 infection rates were 10.4% in women with normal cervix, 14.5% in women with CINⅠ and 41.2% in women with CINⅡ/Ⅲ, respectively. The differences among three groups were significant (P<0.001). Moreover, the infection rates of HPV16 gradually increased with the increasing severity of CIN (trend χ(2)=18.512, P<0.001). The differences in protein expression of hnRNP K among three groups were significant (H=48.138, P<0.001) and the expressionincreased with the development of cervical lesionss (trend χ(2)=21.765, P<0.001). Results from the interaction analysis indicated that there were additive effects between high expression of hnRNP K protein and HPV16 in CINⅡ/Ⅲ group compared with normal group (API=0.639, 95%CI: 0.083-1.196). In contrast, no such additive effect was found in CINⅠ group. Conclusions: HPV16 infection and over-expression of hnRNP K protein were associated with the increased risk of cervical intraepithelial neoplasia. There might be interaction between hnRNP K protein overexpression and HPV16 infection existed on the progress of CINⅡ/Ⅲ.

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 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.

Abstract
Management of complex foot injuries, which involve open fractures and severe trauma to soft tissues, represent a challenge to orthopedic clinicians. In the present case report, we treated a complex foot injury with a remodeled fibular osteocutaneous free flap to reconstruct the anterior and lateral areas of the foot. The flap survived completely. At the 9-month follow-up examination, bony union of the graft bone was identified by radiographic examination. The reconstructed foot could bear body weight, and the patient could maintain a bipedal gait without discomfort. The remodeled fibular osteocutaneous free flap provides an option for functional reconstruction of foot defects.

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
We report measurements of the nuclear modification factor R_{CP} for charged hadrons as well as identified π^{+(-)}, K^{+(-)}, and p(p[over ¯]) for Au+Au collision energies of sqrt[s_{NN}]=7.7, 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV. We observe a clear high-p_{T} net suppression in central collisions at 62.4 GeV for charged hadrons which evolves smoothly to a large net enhancement at lower energies. This trend is driven by the evolution of the pion spectra but is also very similar for the kaon spectra. While the magnitude of the proton R_{CP} at high p_{T} does depend on the collision energy, neither the proton nor the antiproton R_{CP} at high p_{T} exhibit net suppression at any energy. A study of how the binary collision-scaled high-p_{T} yield evolves with centrality reveals a nonmonotonic shape that is consistent with the idea that jet quenching is increasing faster than the combined phenomena that lead to enhancement.

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
Oxidative stress is closely associated with the pathogenesis of various diseases. Orientin (Ori), a flavonoid component isolated from natural plants, possesses antioxidant activity. Accordingly, we focused on exploring the potential therapeutic effects of Ori on hydrogen peroxide (H2O2)-induced oxidative impairment in RAW 264.7 cells and the underlying antioxidative mechanisms. Our findings suggested that Ori exposure effectively alleviated H2O2-stimulated cytotoxicity, inhibited reactive oxygen species (ROS) generation, and glutathione (GSH) depletion, which were involved in induction of heme oxygenase-1 (HO-1) by enhancing the nuclear factor-erythroid 2-related factor 2 (Nrf2) translocation, decreasing the Keap1 protein expression, and increasing the antioxidant response element (ARE) activity. However, knockdown of Nrf2 and HO-1 with siRNA mostly abolished the cytoprotective effects against H2O2-induced cell oxidative injury, reduced the expression of Nrf2 and HO-1, respectively. Moreover, Ori exposure significantly induced a c-Jun NH2-terminal kinase (JNK) and phosphatidylinositol 3-kinase (PI3K)/serine/threonine kinase (AKT) phosphorylation, but JNK and PI3K/AKT inhibitors treatment effectively reduced levels of Ori-enhanced Nrf2 nuclear translocation and HO-1 protein expression, and blocked Ori-inhibited cytotoxicity and ROS accumulation triggered by H2O2 respectively. Taken together, Ori might exhibit a protective role against H2O2-stimulated oxidative damage by the induction of HO-1 expression through the activation of the JNK- and PI3K/AKT-Nrf2 signaling pathways.

Abstract
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.

Abstract
OBJECTIVES To introduce real-time polymerase chain reaction (real-time PCR) into the initial sample screening, to improve the effectiveness of traditional trace sample extraction method. METHODS Serial diluted 9947A was quantified using a Rotor-Gene Q real-time RT-PCR, and the genotype was determined with AmpFℓSTRTM IdentifilerTM Plus PCR kit. Thus a quantitative threshold model was built to obtain complete STR typing from the trace samples. In addition, 903 trace samples were used to verify the reliability. RESULTS When the samples quality concentration was >0.03 ng/μL, the effective STR typing could be directly obtained; when the concentration was >0.01 and ≤0.03 ng/μL, the effective STR typing could be directly obtained by optimizing the PCR thermal cycle parameters (30 cycles); and when the concentration was ≤0.01 ng/μL, no effective map could be obtained even if PCR was optimized. CONCLUSIONS The real-time PCR quantitative threshold model is effective for the screening of trace samples.

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.

[PMID: 29651618 PMCID: PMC6890580 DOI: 10.1007/s00059-018-4698-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2017] [Revised: 02/11/2018] [Accepted: 03/18/2018] [Indexed: 12/31/2022]
Abstract
Background This study assessed the therapeutic effects of renal sympathetic denervation (RDN) on post-myocardial infarction (MI) ventricular remodeling and sympathetic neural remodeling in dogs. The possible mechanisms and optimal time for treatment are discussed. Methods We randomly assigned 30 dogs to five groups: RDN 1 week before MI (RDN1w + MI; n = 6), RDN 1 week after MI (MI1w + RDN; n = 6), RDN 2 weeks after MI (MI2w + RDN; n = 6), control (N; n = 6), and MI (n = 6). A canine model of myocardial infarction was established by interventional occlusion with a gelatin sponge via the femoral artery. Brain natriuretic peptide (BNP) and endothelin-1 (ET-1) levels were measured and echocardiography was performed to assess cardiac function and heart size. All dogs were killed at the end of the experiment and samples of cardiac and renal arteries were obtained. The expression of matrix metalloproteinase (MMP)-2 and MMP-9 in cardiac and of tyrosine hydroxylase (TH) in renal arteries was assessed by immunohistochemistry. Sympathetic innervations in the infarction border zone were investigated via Western blotting and real-time PCR. Results Left ventricular function in the MI group decreased significantly, while plasma BNP and ET-1 levels as well as MMP-2 and MMP-9 expression increased. Compared with the MI group, the RD groups showed significantly reduced MMP‑2, MMP‑9, TH, and growth-associated protein (GAP) 43 expression in the RDN1w + MI, MI1w + RDN, and MI2w + RDN groups was significantly improved. Additionally, the expression of TH in renal arteries decreased after RDN. Conclusion RDN has preventive and therapeutic effects on post-MI ventricular remodeling and sympathetic neural remodeling. The mechanism of RDN is likely mediated through restraint of renal sympathetic nerve activity.

Abstract
Objective: To observe the association of carotid artery plaque with all-cause mortality and cardiovascular events. Methods: A total of 7 017 participants who completed the carotid sonography examination between 2010 and 2011 were selected from the stroke and the elderly prospective cohort Kailuan study. The participants of stroke cohort received health examination between 2006 and 2007, and participants of elderly cohort received health examination between 2010 and 2011. All participants were divided into plaque group (3 285 cases) and without plaque group (3 732 cases) according to with or without carotid artery plaque.The all-cause mortality and cardiovascular events were compared between the 2 groups. Multivariate Cox regression analysis was used to identify the association of carotid artery plaque with all-cause mortality and cardiovascular events. Results: (1) There were 4 297 male (61.2%) and 2 720 female (38.8%) in this cohort and participants were (58.1±11.8) years old. Age, systolic blood pressure, diastolic blood pressure, fasting plasma glucose, total cholesterol, low-density lipoprotein cholesterol, rates of male, smoking, drinking, history of hypertension and diabetes mellitus were higher in the plaque group than in the without plaque group, and high density lipoprotein cholesterol was lower in the plaque group than in the without plaque group (all P<0.01) at baseline. (2) During a follow-up period of (4.92±0.59) years, the incidence rates of all-cause mortality in the plaque group and without plaque group were 5.5% (180/3 285) and 1.5% (57/3 732) ,respectively (P<0.01) .The incidence rates of cardiovascular events in the plaque group and without plaque group were 3.8% (124/3 285) and 1.4% (52/3 732) , respectively (P<0.01) . (3) Multivariate Cox regression analysis showed that carotid plaque was an independent risk factor of all-cause mortality (HR=1.667, 95%CI 1.160-2.395, P<0.01) and cardiovascular events (HR=1.942, 95%CI 1.312-2.876, P<0.01) after adjusting for age, sex, systolic blood pressure, diastolic blood pressure, fasting plasma glucose, body mass index, total cholesterol,low density lipoprotein cholesterol, high density lipoprotein cholesterol, smoking, drinking, history of hypertension and diabetes mellitus, and use of lipid-regulating drugs. Conclusion: Carotid plaque is an independent risk factor of all-cause mortality and cardiovascular events. Clinical Trial Registration Chinese Clinical Trials Registry, ChiCTR-TNC-11001489.

Abstract
Objective: To explore the life span of red blood cells (RBC) in patients with severe/very severe aplastic anemia (SAA/VSAA). Methods: Clinical data of 128 SAA/VSAA patients from November 2016 to April 2017 were retrospectively analyzed, and 13 healthy volunteers in the same period was used as normal control. The endogenous Breath Carbon Monoxide (CO) test was used to detect the life span of RBC in SAA/VSAA patients, and the effect of immunosuppressive therapy (IST) on the life span of RBC in these patients was explored. Results: The mean life span of RBC in 51 untreated SAA/VSAA patients was (50.69±21.43) d, which was significantly shorter than that in normal controls[(111.85±31.55) d](t=-6.611, P<0.001). The mean life span of RBC in 77 patients treated with IST was (87.14±39.28) d. The mean life span of RBC in complete responses (CR), hematologic response (HR) and non-response (NR) patients were (106.15±32.12) d, (92.00±38.60) d and (50.44±21.56) d, respectively. The life span of RBC in patients with HR was significantly longer than that in newly diagnosed and NR patients (t=7.430, P<0.001; t=4.846, P=0.002), which was similar to that in the normal controls (t=-1.743,P=0.085). There was no statistical significance between CR patients and the normal controls in the mean life span of RBC (t=-0.558, P=0.579). No factor affecting the RBC life span was found in univariate logistical regression analyses in the newly diagnosed SAA/VSAA patients. The serum levels of IL-2R and IL-6 were much lower in HR patients than NR patients[IL-2R: 4.3×105 U/L vs 6.5×105 U/L, z=-2.733, P=0.006; IL-6: 2.6 (2.0-17.7) ng/L vs 6.1 (2.0-14.4) ng/L, z=-2.968, P=0.003]. Of the 51 newly diagnosed patients, 38 received IST and their 3-month curative effect was evaluated. Receiver operator characteristics (ROC) curve was used to analyze the predictive effect of RBC life span of untreated patients on the efficacy of IST before treatment. The cut-off point was 60 days with sensitivity of 37.5% and specificity of 86.4%. In 9 cases with life span of RBC>60 d before IST, 6 cases acquired HR, while in 29 cases with life span of RBC ≤ 60 d before IST, 10 cases acquired HR, the difference was not statistically significant (P=0.128). Conclusion: The life span of RBC in SAA/VSAA patients was shortened, which can be improved even recovered to the normal after IST. Elevated cytokines might play a role in the pathophysiology of the shortened RBC life span in SAA/VSAA.

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
Rapidity-odd directed-flow measurements at midrapidity are presented for Λ, Λ[over ¯], K^{±}, K_{s}^{0}, and ϕ at sqrt[s_{NN}]=7.7, 11.5, 14.5, 19.6, 27, 39, 62.4, and 200 GeV in Au+Au collisions recorded by the Solenoidal Tracker detector at the Relativistic Heavy Ion Collider. These measurements greatly expand the scope of data available to constrain models with differing prescriptions for the equation of state of quantum chromodynamics. Results show good sensitivity for testing a picture where flow is assumed to be imposed before hadron formation and the observed particles are assumed to form via coalescence of constituent quarks. The pattern of departure from a coalescence-inspired sum rule can be a valuable new tool for probing the collision dynamics.

Abstract
Objective:To determine the distribution characteristics of inhaled allergens and its influencing factors among allergic rhinitis (AR) patients in Chongqing. Method:Intracutaneous test was carried out in 2 474 AR patients. All the cases were divided into six groups according to age, 6-13 years old, >13-18 years old, >18-29 years old, >29-39 years old, >39-49 years old, >49 years old and four groups on the basis of season (spring, summer, autumn, winter). The correlations between the positive rates and gender, age, season were analyzed. Result:The most common allergens were dermatophagoides farin (71.26%), dermatophagoides pteronyssinus (73.61%) and polyvalent insect (60.79%). There was no significant correlation between most allergens and gender(P>0.05). Statistical analysis was conducted among different age groups, it showed that the positive rates of overwhelming majority allergens were highest in the group of 13-18 years old and higher in 6-13 years old group, and then gradually declined with age with a striking difference in each groups (P<0.05). Similar analysis was carried out among the groups in four seasons. It revealed that the prevalence rates of most allergens were higher in summer and autumn than that in spring and winter (P<0.05). Conclusion:Dermatophagoides and polyvalent insect are the most prevalent inhalant allergens in AR disease in Chongqing. Most AR patients had multiple allergens. The prevalence rates of most allergens were significantly different with age and season.
