Abstract
Objective: To evaluate the relationship between admission mean platelet volume (MPV) and 2-year cardiac mortality in patients with stable coronary artery disease (CAD) undergoing elective percutaneous coronary intervention (PCI), and explored the consistence of this relationship in diabetes mellitus (DM) and non-DM subgroups. Method: A total of 4 293 patients who underwent PCI in Fuwai Hospital in 2013 were enrolled and divided into two groups according to MPV as follows: lower MPV (n=2 219, MPV≤10.5fL) and higher MPV (n=2 074, MPV>10.5fL). Result: Patients with high MPV had a higher rate of DM (30.4%(674/2 219) vs 34.5%(715/2 074)), smoking (53.3%(1 183/2219) vs 57.0%(1 182/2 074)), and previous coronary artery bypass grafting (CABG) (4.0%(88/2 219) vs 5.4%(112/2 074)), while left ventricular ejection fraction (LVEF) (64±7 vs 63±7), and glomerular filtration rate (eGFR) (92±14 vs 91±15) were lower compared with patients in the low MPV group (all P<0.05). In the laboratory examination, patients with high MPV had higher glycosylated hemoglobin, and lower platelet count (all P<0.05). In coronary angiography, there was no significant difference in SYNTAX scores, left main/three-vessel lesions, stent type, success rate of operation, and total stent length (all P>0.05). Compared with low MPV group, patients with high MPV had ahigher cardiac mortality [18 (0.9%) vs 5 (0.2%), P=0.004]. Kaplan-Meier analysis showed that compared to low MPV group, cardiac mortality in high MPV group was significantly higher (Log-rank P=0.004). Multivariate Cox regression analysis showed that high MPV was independently associated with 2-year cardiac mortality (HR 4.127, 95%CI 1.373 to 12.405, P=0.012). Receiver operating characteristic curve (ROC) analysis also showed that MPV had a good diagnostic value in predicting 2-year cardiac mortality (area under the curve=0.624, 95%CI: 0.511-0.738, P=0.04). Subgroup analysis showed that in patients with DM (HR 2.090, 95%CI 1.217-3.589, P=0.008) and male (HR 1.561, 95%CI 1.007-2.421, P=0.047), MPV was significantly related with cardiac mortality. Conclusion: In patients with stable CAD who underwent elective PCI, high MPV was independently associated with an increase in 2-year cardiac mortality, especially in patients with DM and male gender.

Abstract
Objective: To analyze the association between plasma high-density lipoprotein cholesterol (HDL-C) levels and the severity of coronary artery disease, and to evaluate the impact of HDL-C levels on long-term outcomes in patients underwent percutaneous coronary intervention (PCI). Methods: A total of 10 458 consecutive patients underwent PCI from January 2013 to December 2013 at Fuwai hospital were enrolled in this study. Patients were divided into three groups according to HDL-C tertiles: low HDL-C group (HDL-C≤0.89 mmol/L, n=3 525), median HDL-C group (HDL-C>0.89-1.11 mmol/L, n=3 570) and high HDL-C group (HDL-C>1.11 mmol/L, n=3 363). SYNTAX score was used to evaluate the severity of coronary artery disease, linear regression was used to analyze the relationship of HDL-C and SYNTAX score. Kaplan-Meier survival analysis was used to compare the outcomes among the three groups. Multivariate Cox regression was used to define the potential associations of HDL-C and outcomes. Results: The HDL-C level was (1.03±0.28) mmol/L and the SYNTAX score was 11.7±8.1. Patients were older, proportion of female, stable angina pectoris, successful PCI and left ventricular eject fraction value were higher, while incidence of diabetes mellitus was lower, hyperlipidemia, old myocardial infraction, smoking history and left main and three vessels disease were lower in high HDL-C group (all P<0.05). Patients in high HDL-C group also had the lowest SYNTAX score (12.2±8.4 vs. 11.7±8.1 vs. 11.2±7.8, P<0.001). Both univariate and multivariate linear regression analysis showed that HDL-C was negatively associated with SYNTAX score, e.g. Univariate analysis: β=-0.046, P<0.001; Multivariate analysis: β=-0.058, P=0.001. And 10 400 (99.4%) patients completed 2-year follow up. At 2-year follow-up, there were no difference in all-cause death, cardiac death, myocardial infarction, revascularization, stroke, major adverse cardiovascular and cerebral events (MACCE) and stent thrombosis among three groups (P for trend>0.05), while patient in high HDL-C group experienced the highest BARC type 2 bleeding events (P for trend=0.018). Multivariate Cox regression analysis showed that HDL-C level was not an independent risk factor of 2-year adverse ischemia events (P>0.05) and 2-year bleeding events (P>0.05). Conclusion: In patients underwent PCI, plasma HDL-C level is negatively associated with SYNTAX score, but not an independent risk factor of ischemic and bleeding events post PCI.

Abstract
Objective: Using previous total mesorectal excision with pelvic autonomic nerve preservation (PANP+TME) and simple total mesorectal excision (TME) without emphasis on retained nerves as control, we explore the advantages of nerve plane-oriented laparoscopic total mesorectal excision (NPO+LTME) on urinary and sexual function. Methods: A retrospective cohort study was carried out. Case inclusion criteria: (1) male patients with pathologically confirmed middle and low rectal adenocarcinoma (4 to 11 cm from the anus); (2) stage T1-2tumor; (3) normal sexual life before operation. Exclusion criteria: (1) no pathological diagnosis before surgery; (2) local recurrence or distant metastasis; (3) preoperative neoadjuvant chemoradiotherapy; (4) opensurgery and laparoscopic surgery conversionto open; (5) no follow-up data. According to the above criteria, clinical data of 173 male patients with low and middle rectal adenocarcinoma who underwent radical operation for laparoscopic rectal cancer from July 2003 to July 2018 at the Department of Gastrointestinal Surgery, Wuhan University People's Hospital were collected. According to different surgical methods, patients were divided into TME group (58 cases), PANP+TME group (63 cases) and NPO+LTME group (52 cases). There were no significant differences in the baseline data including age, body mass index and pathological examination between the 3 groups (all P>0.05). The nerve plane referred to the nerve, the adipose tissue, the extremely finecapillaries around the nerve with overlying fine membranous tissue. NPO+LTME referred to the process of laparoscopic TME guided by the nerve plane, performing in the loose connective tissue between the nerve plane and the rectal properfascia, in order to ensure the integrity of the nerve plane, and maximally protect the patient's urinary and reproductive functions. The operation time, intraoperative blood loss, urinary catheter removal time, urinary function grading, postoperative first erection time, and erectile function and ejaculation function were observed and compared among the 3 groups at 3- and 6-month after operation. Results: In the NPO+LTME group, the PANP+TME group and the TME group, the operation time was (181.9±24.5) minutes, (176.7±29.2) minutes and (137.7±16.2) minutes, respectively (F=54.868, P<0.001); the intraoperative blood lost was (6.0±1.4) ml, (6.5±1.8) ml and (12.8±4.6) ml, respectively (F=95.016, P<0.001); the time to postoperative removal of the catheter was (2.4±1.1) days, (3.7 ±1.7) days and (6.5±2.4) days, respectively (F=79.409, P<0.001); the first postoperative erection time was (1.6±0.6) days, (8.9±2.7) days and (15.9±6.8) days (F=177.677, P<0.001), respectively, whose differences were all statistically significant (all P<0.01). In comparison of urinary function grading, the proportion of grade I (normal function, no urinary dysfunction) in the NPO+LTME, the ANP+TME group and the TME group was 84.1% (53/63), 39.7% (23/58) and 19.2% (10/52), respectively, and the difference was statistically significant (H=52.915, P<0.001). At postoperative 3- and 6-month, proportion of patients with grade I erectile function (normal erectile function) was 77.8% (49/63) and 85.7% (54/63), 44.8% (26/58) and 53.4% (31/58), 28.8% (15/52) and 48.1% (25/52) in the NPO+LTME group, the PANP+TME group, and the TME group, respectively. The differences were statistically significant (H=91.709, P<0.001; H=79.692, P<0.001). The proportion of patients with grade I ejaculation function (with ejaculation, no abnormalities in routine semen examination before and after surgery) at 3- and 6-month after surgery in the NPO+LTME group, the PANP+TME group and the TME group was 82.5% (52/63) and 87.3% (55/63), 53.4% (31/58) and 60.3% (35/58), 28.8% (15/52) and 46.1% (24/52), respectively. The differences were statistically significant as well (H=86.543, P<0.001; H=78.667, P<0.001). Patients in the NPO+LTME group had no grade III erections and ejaculation disorders. Conclusion: The surgical procedure of NPO+LTME can promote the recovery of postoperative neurological function and preserve urination and sexual function better.

Abstract
In order to study changes in benthic diatom communities and their relationships with environmental factors during different hydrological periods, 32 sites were sampled in the main stream of the Three Gorges Reservoir during the non-storage period (July 2015 to September 2015) and the storage period (December 2015 to March 2016). Results showed that there were significant differences in water temperature (WT), underwater light intensity (PAR), pH, conductivity (Spc), dissolved oxygen (DO), redox potential (ORP), turbidity (Tur), transparency (SD), flow rate (v), and permanganate index between the storage and non-storage periods. Ninety-six species of benthic diatoms, belonging to 28 genera, were identified during the two hydrological periods. Thirteen dominant species and three dominant species were identified during the non-storage period and the storage period, respectively, suggesting that some differences existed in the composition and distribution of dominant species between the two periods. However, Melosira varians, an α-polluting and eutrophic species, was dominant during both of the hydrological periods. Redundancy analysis (RDA) found that pH, flow rate, and orthophosphate (PO43--P) were the main environmental factors affecting the composition of benthic diatom communities, and a significant difference was found between up- and down-stream areas during the non-storage period. In comparison, water temperature, turbidity, permanganate index, and dissolved oxygen (DO) were the main environmental factors influencing the patterns of benthic diatoms communities, for which an insignificant difference was observed between up- and down-stream areas during the storage period. These results suggest that water storage in the Three Gorges Reservoir has an important impact on the composition of benthic diatom communities, and that this results in a change in community structure.

Abstract
Objective: The authors aim to provide genetic counselling and prenatal gene diagnosis to the families with osteogenesis imperfecta(OI), based on the identification of pathogenetic mutations in large cohort genetic testing. Methods: DNA was extracted from the peripheral blood of parents of the fetuses, and from the villi tissue, amniotic fluid or cord blood of the fetuses using a standard sodium dodecyl sulfate-proteinase K-phenol/chloroform extraction method. PCR combined with Sanger DNA sequencing was performed to validate the pathogenic mutations of 200 fetuses at risk of OI and their parents from 158 families. Allelic analysis of microsatellite markers was applied to exclude the false positive caused by maternal DNA contamination, when both the fetus and the mother harbored the same pathogenic genotype. Results: A total of 83 affected fetuses (83/200, 41.5%) and 12 (12/200, 6.0%) recessive carriers were identified among the 200 fetuses. The 83 affected fetuses included 78 heterozygotes (45 of COL1A1, 32 of COL1A2, one of IFITM5), and 5 compound heterozygotes or homozygotes of recessive OI (two of FKBP10, one of SEC24D, one of WNT1 and one of CRTAP); The 12 recessive carriers included 7 of WNT1, 4 of SERPINF1 and one of SERPINH1. Maternal DNA contamination was excluded from the genomic DNA samples of OI fetuses when their mother with the same affected genotypes. Conclusion: In this study, the authors used an optimized gene diagnosis system of OI to perform prenatal genetic diagnosis to 200 fetuses at high risk of OI, and provided precisely genetic counselling to the OI families.

Abstract
Objective: To compare the clinical characteristics and long-term prognosis between male and female patients with premature coronary artery disease (PCAD) post coronary intervention, and analyse the risk factors of major adverse cardio-cerebrovascular events (MACCE) and bleeding events. Methods: This was a prospective single-center observational study. From January 2013 to December 2013, 4 744 patients diagnosed as PCAD and treated with percutaneous coronary intervention (PCI) in Fuwai Hospital were enrolled. The general clinical data, laboratory results and interventional treatment data of all patients were collected, and patients were followed up for 2 years after PCI and the incidence of events including MACCE and bleeding was analyzed. The baseline data and clinical events of PCAD patients of different genders were compared. Survival curves were estimated by Kaplan-Meier method. Univariate and multivariate Cox regression were used to analyze whether gender was an influencing factor of different clinical events of PCAD patients within 2 years after PCI, and other relevant influencing factors of MACCE and bleeding events. Results: Among the 4 744 PCAD patients included, there were 3 390 (71.5%) male aged (47.0±5.4) years old and 1 354 (28.5%) female aged (57.0±5.8) years old. Compared with female patients, male patients had higher body mass index, higher proportion of hyperlipidemia, smoking, myocardial infarction, previous PCI, preoperative estimated glomerular filtration rate, ST-segment elevation myocardial infarction, radial artery approach, intravenous ultrasound use and chronic occlusive lesions (all P<0.05). Age, left ventricular ejection fraction, prevalence of hypertension, diabetes mellitus, past stroke history, non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and the use of calcium channel blockers were lower in male patients than in female patients (all P<0.05). The 2-year follow-up results showed that the incidence of BARC type 1 hemorrhage was significantly higher in female patients than in male patients (6.9%(92/1 343) vs. 3.7%(126/3 378), P<0.001); however, the incidence of MACCE, all-cause death, cardiac death, recurrent myocardial infarction, revascularization (target vessel revascularization and target lesion revascularization), stent thrombosis, stroke and BARC type 2-5 hemorrhage were similar between the two groups (all P>0.05). Multivariate Cox regression analysis showed that gender was an independent risk factor for BARC type 1 bleeding in PCAD patients (HR=2.180, 95%CI 1.392-3.416, P<0.001), but it was not an independent risk factor for MACCE and BARC type 2-5 bleeding(all P>0.05). Hyperlipidemia, preoperative SYNTAX score, multivessel lesions and NSTE-ACS were the independent risk factors for MACCE in PCAD patients with PCI (the HRs(95%CI) were 1.289(1.052-1.580), 1.030(1.019-1.042), 1.758(1.365-2.264), 1.264(1.040-1.537), respectively); gender (HR=1.579, 95%CI 1.085-2.297, P=0.017), hyperlipidemia (HR=1.305, 95%CI 1.005-1.695, P=0.046), anticoagulant drugs including low molecular weight heparin (HR=1.321, 95%CI 1.002-1.741, P=0.048) or sulfonate(HR=1.659, 95%CI 1.198-2.298, P=0.002) were the independent risk factors for bleeding events. Conclusions: There are differences in clinical and coronary artery lesion characteristics between different genders in patients with PCAD. The incidence of minor bleeding is significantly higher in female PCAD patients than in male PCAD patients. Hyperlipidemia, preoperative SYNTAX score, multivessel lesions and NSTE-ACS are the independent risk factors for MACCE, and gender, hyperlipidemia, anticoagulant drugs including low molecular weight heparin or sulfonate are the independent risk factors for bleeding events in patients with PCAD.

Abstract
Abstract
Background and purpose
Limited data is available on the situation of cardiogenic shock (CS) complicating ST-elevated myocardial infarction (STEMI) in China. This study aims to disclose the incidence, management and in-hospital mortality (IHM) of patients with STEMI complicated by CS (STEMICS) in China and at different levels of hospitals.
Methods
We queried the 2013–2016 China Acute Myocardial Infarction (CAMI) registry databases to identify patients with STEMI and/or CS (developing before or during hospitalization). The overall and different hospital-level incidence of STEMICS and IHM were analyzed.
Results
Of 28230 STEMI patients, 2273 patients (8.05%) had CS. The incidence of STEMICS in provincial, prefectural and county-level hospitals were 5.23%, 8.46% and 13.76% (p<0.001), respectively. Primary PCI (PPCI) was performed on 675 patients (29.7%) with STEMICS. The proportion of STEMICS patients undertaking PPCI in provincial, prefectural and county-level hospitals were 46.53%, 31.48% and 8.00% (p<0.001). The overall IHM rate of patients with STEMICS was 49.8% with no difference among the different hospital levels. However, the IHM rate of prehospital STEMICS in county-level hospitals were significantly higher than that in prefectural and provincial hospitals (42.3% versus 33.3% and 28.3%, respectively; p<0.01), while that of in-hospital STEMICS were similar among the different hospital levels (66.5%, 66.9% and 62.2%; provincial, prefectural and county-level hospitals, respectively). After adjustment, the difference of IHM in prehospital STEMICS between county-level hospitals and the other two levels no longer existed. However, once PPCI was excluded from the multivariable adjustment model, the IHM of prehospital STEMICS remained higher in county-level hospitals.

Differences in IHM of prehospital STEMICS between county-level hospitals and other two levels of hospitals before or after adjustment Provincial hospitals/ County-level hospitals Prefectural hospitals/ County-level hospitals Unadjusted OR (95% CI) 0.54 (0.36, 0.80); P=0.0019 0.68 (0.49, 0.94); P=0.0193 Adjusted OR* (95% CI) 0.63 (0.34, 1.17); P=0.1455 0.64 (0.38, 1.08); P=0.0962 Adjusted OR† (95% CI) 0.49 (0.27, 0.90); P=0.0214 0.54 (0.32, 0.91); P=0.0198 IHM: in-hospital mortality; OR: odd ratio; CI: confidence interval. *Adjusted for baseline characteristics, in-hospital medications and primary PCI; †adjusted for baseline characteristics and in-hospital medications.
Figure 1. Flowchart
Conclusion
The overall incidence and IHM rate of STEMICS in China are still high. Especially, higher IHM rate of prehospital STEMICS is observed in county-level hospitals, which may be attributed to the lower implementation rate of PPCI.

Abstract
Abstract
Aims
We aim to investigate the effect of single dose of statin pretreatment prior to primary Percutaneous Coronary Intervention (PCI) on long-term clinical outcomes in patients with ST-elevation Myocardial Infarction (STEMI).
Methods
Using data from China Acute myocardial Infarction (CAMI) registry, we compared the outcome in STEMI patients with vs without atorvastation pretreatment prior to primary PCI. The primary endpoint was the composite outcome of all-cause mortality, non-fatal MI or stroke events during follow-up. Propensity-score (PS) matching was used to assemble a cohort of patients with similar baseline characteristics. All patients were followed till 24 months since baseline.
Results
Of all 3772 patients who met our inclusion criteria at 108 hospitals in China, 3288 patients (1644 patients in each arm) were included in our PS-matched cohort. In the PS-match cohort, overall 144 (8.65%) and 113 (6.79%) patients in the control group and pretreatment group had the primary endpoint respectively (p=0.048). The estimated HRs were 0.78 (95% CI: 0.606–0.997, p=0.046) in the unadjusted model and 0.76 (95% CI: 0.596–0.984, p=0.032) in the adjusted model (Figure). The HRs were broadly similar for the pretreatment dosage of 40 mg or 80 mg (0.78 vs 0.77, p=0.75). The HRs were even stronger in patients with single-vessel only than multi-vessel coronary artery disease (0.31 vs 0.75, p=0.014).
Conclusion
Among Chinese patients with STEMI, atorvastatin pretreatment before primary PCI may have better long-term composite outcome of all-cause mortality, non-fatal MI, or stroke events.

It is recommended to base revascularization strategy on the clinical status, comorbidities and lesion characteristics in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS). However, the risk and benefit of Culprit Lesion Only (CVO) versus Multi-vessel One-stage Intervention (MVOI) is unclear. We aim to compare the long-term prognosis of NSTE-ACS undergoing CVO and MVOI PCI strategy.
Method
A total of 4768 consecutive patients with NSTE-ACS who underwent PCI in our hospital in 2013 were enrolled in this study. Patients were divided into CVO group and MVOI group according to whether the culprit vessel was the only target vessel. Prognosis impact on 2-year major adverse cardiovascular and cerebrovascular events (MACCE) is analyzed across 2 groups, including death, cardiac death, myocardial infarction, unplanned revascularization, in-stent thrombosis, stroke and bleeding.
Results
Compared with CVO group, MVOI patients had generally worse clinical baseline characteristics and angiographic findings, including higher BMI, SYNTAX score, higher proportion of diabetes, hypertension, NSTEMI, tri-vessel disease, total occlusion, etc. Two-year follow-up revealed that MVOI patients have significantly higher rate of unplanned revascularization (10.1% vs. 7.9%, p=0.018), stroke (2.2% vs. 1.3%, p=0.042) and MACCE (14.0% vs. 11.3%, p=0.012). Kaplan-Meier survival analysis yielded similar results. After adjusting for confounding factors by Cox regression analysis, MVOI was shown to be independently associated with higher rate of 2-year in-stent thrombosis (HR = 3.718, 95% CI: 1.125 - 12.293).
Two-year Clinical Outcomes CVO (n=3634) MVOI (n=1134) P value All-cause Death 39 (1.1) 13 (1.1) 0.836 Cardiac Death 18 (0.5) 8 (0.7) 0.402 Myocardial Infarction 64 (1.8) 22 (1.9) 0.693 Unplanned Revascularization 287 (7.9) 115 (10.1) 0.018 In-stent Thrombosis 26 (0.7) 12 (1.1) 0.257 Stroke 49 (1.3) 25 (2.2) 0.042 Bleeding 253 (7.0) 67 (5.9) 0.216 MACCE 409 (11.3) 159 (14.0) 0.012 CVO = Culprit Vessel Only; MVOI = Multivessel One-stage Intervention; MACCE = Major Adverse Cardiac and Cerebrovascular Events.
Cox Regression Analysis on CVO/MVOI
Conclusion
In our large cohort of Chinese patients, MVOI strategy for NSTE-ACS patient undergoing PCI was associated with worse 2-year prognosis compared with CVO strategy. MVOI is an independent risk factor for 2-year in-stent thrombosis.

Abstract
Abstract
Background
Prediction of in-hospital bleeding is critical for clinical decision making for acute myocardial infarction (AMI) patients undergoing percutaneous coronary intervention (PCI). Machine learning methods can automatically select the combination of the important features and learn their underlying relationship with the outcome.
Objective
We aim to evaluate the predictive value of machine learning methods to predict in-hospital bleeding for AMI patients.
Methods
We used data from the multicenter China Acute Myocardial Infarction (CAMI) registry. We randomly partitioned the cohort into derivation set (75%) and validation set (25%). Using data from the derivation set, we applied a state-of-art machine learning algorithm, XGBoost, to automatically select features from 106 candidate variables and train a risk prediction model to predict in-hospital bleeding (BARC 3, 5 definition).
Results
16736 AMI patients who underwent PCI were consecutively included in the analysis, while 70 (0.42%) patients had in-hospital bleeding followed the BARC 3,5 definition of bleeding. Fifty-nine features were automatically selected from the candidate features and were used to construct the prediction model. The area under the curve (AUC) of the XGBoost model was 0.816 (95% CI: 0.745–0.887) on the validation set, while AUC of the CRUSADE risk score was 0.723 (95% CI: 0.619–0.828).

Abstract
Objective:The results of the detection of the serum inhalant allergen in children with adenoid hypertrophy in Yantai were analyzed, and the common inhalant allergens and their distribution in the children with adenoid hypertrophy were found. Method:Serum inhaled allergen specific IgE(sIgE) was measured in 590 cases of adenoid hypertrophy from Nov 2017 to Oct 2018 by Symer allergen detection system, and stratified according to sex, age and visiting season. The distribution of inhaled allergens in serum of children with adenoid hypertrophy was described. Result:The positive rate of serum inhaled allergens in children with adenoid hypertrophy in Yantai area was 34.07%. Among them the most common inhaled allergens were dust mite(19.66%), dust mite(18.98%) and the mixed mold(17.97%). The positive degree of allergen in children with adenoid hypertrophy was mild(93 cases), moderate(88 cases), and severe(20 cases). 76 cases were positive for single allergens, 79 cases were positive for 2 allergens, and 56 cases were positive for three or more allergens. Stratified study showed that there was no significant difference in the positive rate of inhaled allergens between male and female children(P>0.05), but the positive rate of mixed mold and animal dandruff allergens in male children was higher than that in female children(P<0.05). There was no significant difference in the positive rate of inhaled allergens between pre-school and school-age children(P>0.05), and there was no significant difference in the positive rate of inhaled allergens in different seasons(P>0.05). Conclusion:Dust mite, dust mite and mildew mixture were the most common inhaled allergens in children with adenoid hypertrophy in Yantai area. The positive degree of serum allergens in children with adenoid hypertrophy was mild to moderate, and most of the children were allergic to two kinds of allergens. Male children were more susceptible to mold mixing and animal dandruff. There was no significant difference in age and seasonal distribution of common inhaled allergens.

Abstract
Abstract
Background
Controversy exists regarding the use of beta-blockers (BBs) among patients with acute myocardial infarction (AMI) in contemporary reperfusion era. Previous studies predominantly focused on beta-blockers prescribed at discharge, and the effect of long-term adherence to beta-blocker on major adverse cardiovascular events (MACE) remains unclear.
Objective
To explore the association between long-term beta-blocker use patterns and MACE among contemporary AMI patients.
Methods
We enrolled 7860 patients with AMI, who were discharged alive and prescribed with BBs based on CAMI registry from January 2013 to September 2014. Patients were divided into two groups according to BBs use pattern: Always users group (n=4476) were defined as patients reporting BBs use at both 6- and 12-month follow-up; Inconsistent users group were defined as patients reporting at least once not using BBs at 6- or 12-month follow-up. Primary outcome was defined as MACE at 24-month follow-up, including all-cause death, non-fatal MI and repeat-revascularization. Multivariable cox proportional hazards regression model was used to assess the association between BBs and MACE.
Results
Baseline characteristics are shown in table 1. At 2-year follow-up, 518 patients in inconsistent users group (15.6%) and 548 patients in always users group (12.3%) had MACE. After multivariable adjustment, inconsistent use of BBs was associated with higher risk of MACE (HR: 1.323, 95% CI: 1.171–1.493, p<0.001).
Table 1 Baseline characteristics Variable Always user (N=4476) Inconsistent user (N=3384) P value Age (years) 60.6±12.0 61.2±12.2 <0.001 Male 3381 (75.7%) 2461 (74.3%) 0.084 Diabetes 892 (20.0%) 610 (18.4%) 0.003 Hypertension 2372 (53.2%) 1543 (46.6%) <0.001 Dyslipidemia 244 (5.5%) 126 (3.8%) <0.001 Prior myocardial infarction 351 (7.9%) 232 (7.0%) <0.001 Heart failure 88 (2.0%) 63 (1.9%) <0.001 Chronic obstructive pulmonary disease 66 (1.5%) 60 (1.8%) <0.001 Current smoker 2054 (46.1%) 1579 (47.8%) 0.179 Left ventricular ejection fraction (%) 53.7±11.48 54.0±10.9 <0.001 Major Adverse Cardiovascular Events 548 (12.3%) 518 (15.6%) <0.001
Conclusions
Our results showed consistent BBs use was associated with reduced risk of MACE among patients with AMI managed by contemporary treatment.

Abstract
Abstract
Background
The prevalence and prognosis of familial hypercholesterolemia (FH) with acute myocardial infarction (AMI) in China is unclear.
Purpose
To invistigate the prevalence and prognosis of familial hypercholesterolemia (FH) with acute myocardial infarction (AMI) in China.
Methods
In China Acute Myocardial Infarction (CAMI) Registry, 13,002 patients with age 18–80 were consecutively enrolled with first-onset acute myocardial infarction who were naïve to statin before admission from Januanry 1st, 2013 to October 31st, 2014. According to Dutch Lipid Clinical Network Criteria (DLCNC), the patients were divided to heterozygous familial hypercholesterolemia (HeFH) (definite or probable HeFH, possible HeFH) or no HeFH group. All the patients were followed up (average follow-up period, 24 months) and composite major adverse cardiovascular events (ENDPOINT) were recorded which were defined as all-cause death, non-fatal myocardial reinfarction and stroke. Cox regression was performed to analyze the difference of composite endpoint occurrence between HeFH group and no HeFH group.
Results
The number of the patients in the three groups was as following, 62 in definite or probable HeFH group, 484 in possible HeFH group, 12456 in no HeFH group. The prevalence of HeFH is 4.2% (including 0.47% of definite or probable HeFH, 3.73% of possible FH). The average age of onset of first-time AMI was 54±12,56±12,63±12 years old (p<0.0001) in definite or probable HeFH group, possible HeFH group and no HeFH group, respectively. The percentage of Killip III or above (8.1% vs 4.3% vs 6.3%, p=0.1629), cardiac arrest (1.6% vs 0.6% vs 0.9%, p=0.6990), and TIMI 0–2 grade after primary percutaneous cardiac intervention (PCI) (0% vs 6.8% vs 4.3%, p=0.5866) was not significantly different in definite or probable HeFH group, possible HeFH group and no HeFH group, respectively. After Cox proportional analysis adjusting multiple factors, the rate of composite endpoint during follow-up period was not significantly different (definite or probable HeFH group vs no HeFH group, HR 0. 853, 95% CI 0.381–1.910, p=0.699, possible HeFH group vs no HeFH group, HR1.076, 95% CI 0.795–1.458, p=0.635).
The prognosis of FH with AMI in China
Conclusions
In CAMI Registry, the prevalence of HeFH was 4.2%, the diagnosis of HeFH was not a dependent risk factor for the rate of composite cardiovascular events.

Abstract
Abstract
Background
Although primary percutaneous coronary intervention (pPCI) is the optimal reperfusion method for ST-segment elevation myocardial infarction (STEMI), it remains difficult to implement in many areas. Some STEMI patients have to accept fibrinolytic therapy and no reperfusion therapy instead.
Purpose
The aim of this study was to describe the impact of reperfusion therapy on the long-term outcomes of STEMI patients in China.
Methods
Using data from the China Acute Myocardial Infarction (CAMI) registry, we analyzed the 2-year outcomes of 18,075 STEMI patients symptom onset within 7 days from January 2013 to September 2014 according to the type of reperfusion therapy. The primary endpoint was a composite of major adverse cardiovascular event (MACE), defined as all-cause mortality, myocardial infarction or stroke.
Results
7798 (43%) were treated with pPCI and 1798 (10%) underwent fibrinolysis; 8479 (47%) did not receive any reperfusion. The 2-year MACE was 9.6% following pPCI, 15.7% following fibrinolysis, and 21.5% for patients without reperfusion therapy (P<0.0001). Adjusted hazard ratios for 2-year MACE were 0.71 (95% confidence interval [CI] 0.65–0.78, P<0.0001) for pPCI versus no reperfusion and 0.92 (95% CI 0.82–1.03, P=0.16) for fibrinolysis versus no reperfusion. Compared with patients without reperfusion, fibrinolysis only showed benefit in patients presented within 3 hours of symptom onset (HR 0.70, 95% CI 0.57–0.85, P=0.0005), whereas pPCI was associated with significantly decreased 2-year MACE rate in patients presented within 3 hours (HR 0.53, 95% CI 0.44–0.64, P<0.0001), 3–6 hours (HR 0.60, 95% CI 0.51–0.71, P<0.0001) and >6 hours (HR 0.86, 95% CI 0.76–0.97, P=0.01) of symptom onset.
Adjusted cumulative MACE rate
Conclusions
In a real-world setting, early reperfusion is the optimal strategy for STEMI. Fibrinolysis was not associated with better outcome in STEMI patients admitted >3 hours of symptom onset in Chinese real world setting.

Abstract
Objective: To evaluate the effect of ABO blood groups on long-term outcome of stable coronary artery disease (CAD) after percutaneous coronary intervention (PCI). Methods: A total of 4 272 patients with stable coronary artery disease and received PCI were consecutively enrolled from January to December 2013 and followed up for 2 years. Patients were divided into O group and non-O group according to their ABO groups. Multivariable COX regression was used to evaluated the relationship between ABO blood groups and prognosis of CAD. The endpoints included all-cause death, cardiac death, myocardial infarction(MI), revascularization, and stroke. Results: There were 1 302 patients in O group and 2 970 patients in non-O group. ABO blood group was not associated with age, sex and blood pressure (P>0.05). The comorbidity rate of hypertension, diabetes mellitus, smoking, family history, previous MI, previous cerebrovascular disease, previous PCI and left ventricular ejection fraction were similar between the two groups (P>0.05). Total cholesterol, low density lipid cholesterol level were significantly higher in non-O group compared with O group [(4.2±1.1)mmol/L vs (4.1±1.1)mmol/L, P=0.027; (2.5±0.9)mmol/L vs (2.4±0.9) mmol/L, P=0.025], while high density lipid cholesterol level was significantly lower[(1.04±0.26) mmol/L vs (1.06±0.28) mmol/L, P=0.035]. As to angiographic results, non-O blood group was not related to the severity of coronary atherosclerosis assessed by SYNTAX score(P=0.277). More cardiac death occurred in non-O group compared with that in O group [21 (0.7%) vs 2(0.1%)] during 2-year follow-up. After adjusted for confounding factors, multivariable COX regression revealed that non-O blood type was not associated with increased cardiac death [HR (95%CI)=7.30(0.97-55.09), P=0.054]. Conclusion: Non-O blood group is associated with 2-year cardiac death in patients with stable coronary artery disease who received PCI, but it is not an independent risk factor for cardiac death.

Abstract
The aim of this paper was to study the effect of total flavones of Clematis filamentosa Dunn(TFCD) post-conditioning against myocardial ischemia-reperfusion injury (MIRI) and the role of PI3K/Akt-eNOS signaling pathway. Forty male SD rats were divided randomly into five groups: Sham group, model group (I/R), TFCD post-conditioning group (TFCD), TFCD post-condition-ing+LY294002 (a PI3K/Akt signaling pathway inhibitor) group (TFCD+LY), and LY294002 group (LY). At the end of reperfusion, hemodynamic parameters were recorded, morphology changes of myocardial tissue were evaluated by using HE staining, and myocardial infarct size were observed, blood samples were obtained to determine plasma activation of lactate dehydrogenase (LDH), creatine kinase (CK) nitric oxide (NO), endothelial nitric oxide synthase (eNOS), superoxide dismutase (SOD), maleic dialdehyde (MDA) and glutathione peroxidase (GSH-Px). The expressions of Akt, p-Akt, eNOS and p-eNOS proteins were assessed by using Western blot, and eNOS and inducible nitric oxide synthase (iNOS) mRNA was measured by RT-PCR. The results showed that, compared with the model group, TFCD post-conditioning remarkably improved hemodynamics function and myocardial structure, reduced myocardial infarct size and enhanced the contents of NO, eNOS, SOD and GSH-Px, and decreased the contents of LDH, CK and MDA, increased the levels of phosphorylation of Akt and eNOS protein expression, eNOS and iNOS mRNA expression significantly(P<0.05 or P<0.01). These effects were inhibited by LY294002, a blocker of PI3K/Akt signaling pathway. The above experiments indicated that TFCD post-conditioning could significantly reduce MIRI in rats, the mechanism of which may be associated with increasing antioxidation, scavenging oxygen free radicals, regulating NO generation and activating PI3K/Akt-eNOS signaling pathway.

Abstract
Objective: To evaluate the diagnostic value of the heparin-binding protein (HBP), procalcitonin (PCT) and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score in ventilator-associated pneμmonia (VAP). Methods: A total of 160 patients who required tracheotomy or intubation and assisted breathing with invasive mechanical ventilator from the First Affiliated Hospital of Zhengzhou University from January 2015 to January 2017 was included in this prospective study,and divided into VAP group and no-VAP group based on if VAP happened or not; the VAP group was further divided into deterioration group and improvement group based on the curative effect after anti-infective treatment for 1 week. A total of 40 community acquired pneumonia (CAP) patients and 30 healthy volunteers were also included as control groups. The levels of HBP and PCT in blood of the subjects were tested with enzyme-linked immuno sorbent assay (ELISA) and chemiluminescence immunoassay (ECLIA) respectively, APACHE Ⅱ score was utilized to assess the severity of illness. The difference of HBP, PCT levels and APACHE Ⅱ score among the groups were analyzed. Receiver operating characteristic(ROC) curve was utilized to analyze the diagnostic value of HBP, PCT, APACHE Ⅱ score in VAP. Results: A total of 230 subjects participated in this study, including 68 VAP patients, 92 non-VAP patients, 40 CAP patients and 30 healthy volunteers. Before administration of mechanical ventilation, there were no statistically significant differences in HBP, PCT and APACHE Ⅱ score between VAP group and non-VAP group (all P>0.05). The levels of HBP,PCT and APACHE Ⅱ score were (41.4±21.3) μg/L,(0.355±0.254) μg/L,(13.4±2.5) respectively when the VAP was diagnosed,which were higher than those within the first 12 h of mechanical ventilation (7.3±2.7) μg/L, (0.080±0.038) μg/L, (8.4±2.0), all P<0.001). The HBP, PCT and APACHE Ⅱ score had no significant difference between within the first 12 h of mechanical ventilation and after mechanical ventilation in non-VAP group (all P>0.05). The levels of HBP was positively correlated with PCT and APACHE Ⅱ score (r=0.82, 0.68, all P<0.001). In deterioration group,the HBP,PCT and APACHE Ⅱ score after 1 week of anti-infective treatment were higher than those when the VAP was diagnosed (all P<0.001). No matter it is when the VAP was diagnosed or after anti-infective treatment for 1 week,the levels of HBP, PCT and APACHE Ⅱ score in deterioration group were higher than those in the improvement group (all P<0.001). The area under curve (AUC) of HBP+APACHE Ⅱ score, PCT+APACHE Ⅱ score for VAP diagnosis was 0.98, 0.95 respectively. The sensitivity of HBP+APACHE Ⅱ score in the diagnosis of VAP was lower than PCT+APACHE Ⅱ score (94.1% vs 95.6%),and the specificity was higher (92.4% vs 82.6%). Conclusion: The diagnostic value of HBP+APACHE Ⅱ score for early VAP is superior to PCT+APACHE Ⅱ score.

Abstract
In order to explore the composition of epiphytic algae and its related environmental factors, 12 sampling sites in the natural reaches and the backwater reaches (including perennial backwater sections and fluctuating backwater sections) were investigated among tributaries of the Caotang River, the Meixi River, and the Daxi River in the Fengjie district of the Chongqing section of the Three Gorges Reservoir under different hydrological regimes (i.e., storage and non-storage periods). Results showed that 103 species of epilithic algae belonging to 45 genera and 4 families are found in the 3 tributaries. This included 67 species belonging to 34 genus in the natural sections and 82 species (64 species in perennial backwater sections and 41 species in fluctuating backwater sections) belonging to 34 genera in the backwater sections. During the storage period, the dominant species in the natural sections were Melosira varians, Cocconeis placentula, Diatoma vulgure, Gyrosigma scalproides, and Oscillatoria tenuis, while the dominant species in the backwater sections were M. varians, Cymbella affinis,D. vulgure, Eucapsis alpina, and M. granulata. During the non-storage period, the dominant species in the natural sections were M. varians, C. affinis, and C. placentula, whereas the dominant species in the backwater sections were O. princeps, O. rupicola,O. formosa, Synedra acus, Ulothrix sp., Merismopedia elegans, and O. tenuis. These results suggested that the compositions of dominant species showed significant differences during the non-storage period, while little difference was found during the storage period. In addition, the dominant species did not show a significant change in the natural sections, but a marked difference was observed in the backwater sections. Similar dominant species were observed in both perennial and fluctuating backwater sections during the non-storage period, but significantly different dominant species were found during the storage period. Redundancy analysis suggested that the composition of epilithic algae was influenced by different environmental factors, such as temperature, electrical conductivity, pH, total nitrogen, and total phosphorus. Indeed, changes in the cell densities of dominant algae at the different sites were mainly affected by temperature and the concentrations of nitrogen and phosphorus. These results suggest that the different hydrological regimes had an important role not only on the reservoir water environment, but also the dynamics of epilithic algal communities.

Abstract
Objective: To evaluate the prognostic value of the thrombolysis in myocardial infarction (TIMI) and global registry of acute coronary events (GRACE) risk scores for in-hospital mortality in Chinese non-ST-segment elevation myocardial infarction (NSTEMI) patients. Methods: Data of present study derived from the prospective, multi-center registry trial of Chinese AMI (CAMI). Among 31 provinces, municipalities or autonomous districts in China, at least one tertiary and secondary hospital was selected. From January 2013 to September 2014, 5 896 consecutive non-ST-segment elevation myocardial infarction patients who were admitted to 107 hospitals within 7 days of symptom onset were enrolled. For each patient, TIMI and GRACE risk scores were calculated using specific variables collected at admission. Their prognostic value was evaluated by the endpoint of in-hospital mortality. Results: Among 5 896 NSTEMI patients (age was (65.4±12.1) years old), 68.2% (n=4 020) were males. The in-hospital mortality was 6.0% (n=353) and the median length of hospital stay was 10.0 (7.0, 13.0) days. The incidence of pre-hospital cardiac arrest was 3.6% (n=213) among 5 896 NSTEMI patients. Six hundreds and forty five patients (10.9%) received primary percutaneous coronary intervention, and 6 patients underwent emergent coronary artery bypass grafting surgery (0.1%), and the median time of reperfusion was 529.5 (256.0, 1 065.0) minutes. The prescription percentage of statins, β-blocker, angiotensin converting enzyme inhibitors or angiotensin Ⅱ receptor blockers, and aldosterone antagonists were 94.8% (n=5 587), 71.7% (n=4 228), 65.5% (n=3 864) and 26.0% (n=1 533) respectively. The area under the curve of GRACE risk score for in-hospital mortality (0.7930 (95%CI 0.767-0.818)) was better than that of TIMI risk score (0.5588 (95%CI 0.532-0.586), P<0.001). Conclusion: GRACE risk score demonstrates better predictive accuracy than TIMI risk score for in-hospital mortality in NSTEMI patients in this patient cohort.

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
The RASopathies are a group of syndromes that have in common germline mutations in genes that encode components of the RAS/mitogen-activated protein kinase (MAPK) pathway and have been a focus of study to understand the role of this pathway in development and disease. These syndromes include Noonan syndrome (NS), NS with multiple lentigines (NSML), neu-rofibromatosis type 1 (NF1), Costello syndrome (CS), cardio-facio-cutaneous (CFC) syndrome, neurofibromatosis type 1-like syndrome (NFLS) and capillary malformation-arteriovenous malformation syndrome (CM-AVM). These disorders affect multiple systems, including the craniofacial complex. Although the crani-ofacial features have been well described and can aid in clinical diagnosis, the dental phenotypes have not been analysed in detail for each of the RASopathies. In this review, we summarize the clinical features of the RASopathies, highlighting the reported craniofacial and dental findings.

Abstract
Objective: Patients with acute coronary syndrome due to multivessel disease (MVD) were at the highest risk of adverse cardiovascular events. Neutrophil to lymphocyte ratio (NLR) was proposed as a marker of cardiovascular risk. Present study evaluated the independent predictive value of NLR for acute myocardial infarction (AMI) patients with MVD. Methods: AMI patients with MVD (n=1 433) underwent percutaneous coronary intervention (PCI) between January 2013 and December 2013 were followed up for 2 years. Patients were divided into 2 sub-groups based on an optimal cut off value of NLR to predict 2-year all-cause mortality. The primary endpoint was all-cause death. The secondary endpoint was long-term major adverse cardiovascular and cerebrovascular events (MACCE). Results: By receiver operating characteristics curve analysis, the optimal cut-off value of admission NLR to predict 2-year all-cause mortality was 3.39 (area under the curve 0.765, sensitivity 71%, specificity 73%). The high NLR group(n=396) had higher prevalence of prior myocardial infarction, prior PCI and intra-aortic balloon pump use (IABP)(P<0.01). Compared to the low NLR group (n=1 037), patients in the high NLR group were older, had higher level of neutrophil count and high-sensitivity C-reactive protein (hs-CRP) (P<0.001), but lower level of lymphocyte count, estimated glomerular filtration rate (eGFR) and ejection fraction (P<0.001). During the follow-up period, rate of long-term all-cause death was significantly higher in the high NLR group than in the low NLR group (5.1% (20/396) vs. 0.8% (8/1 037), P<0.001). Cardiac death (4.0% (16/396) vs. 0.7% (7/1 037), P<0.001) and MACCE (21.7% (86/396) vs. 12.6% (131/1 037), P<0.001) were also significantly higher in the high NLR group than in the low NLR group. Multivariate Cox analysis showed that NLR ≥ 3.39 was determined as an independent predictor of 2-year all-cause mortality (HR=3.23, 95%CI 1.38-7.54, P=0.007) and MACCE (HR=1.58, 95%CI 1.19-2.10, P=0.002) in this patient cohort after adjusting for other risk factors. Correlation analysis showed that the NLR was positively correlated with hs-CRP levels (r=0.241, P<0.001). Conclusion: Our study demonstrates that admission NLR ≥ 3.39 is an independent predictor of long term all cause death and MACCE in AMI patients with MVD post PCI.

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.
