BACKGROUND: There are few data comparing clinical outcomes of complex percutaneous coronary intervention (CPCI) when using biodegradable polymer drug-eluting stents (BP-DES) or second-generation durable polymer drug-eluting stents (DP-DES). The purpose of this study was to investigate the safety and efficacy of BP-DES and compare that with DP-DES in patients with and without CPCI during a 5-year follow-up. METHODS: Patients who exclusively underwent BP-DES or DP-DES implantation in 2013 at Fuwai Hospital were consecutively enrolled and stratified into two categories based on CPCI presence or absence. CPCI included at least one of the following features: unprotected left main lesion, ≥2 lesions treated, ≥2 stents implanted, total stent length >40 mm, moderate-to-severe calcified lesion, chronic total occlusion, or bifurcated target lesion. The primary endpoint was major adverse cardiac events (MACE) including all-cause death, recurrent myocardial infarction, and total coronary revascularization (target lesion revascularization, target vessel revascularization [TVR], and non-TVR) during the 5-year follow-up. The secondary endpoint was total coronary revascularization. RESULTS: Among the 7712 patients included, 4882 (63.3%) underwent CPCI. Compared with non-CPCI patients, CPCI patients had higher 2- and 5-year incidences of MACE and total coronary revascularization. Following multivariable adjustment including stent type, CPCI was an independent predictor of MACE (adjusted hazard ratio [aHR]: 1.151; 95% confidence interval [CI]: 1.017-1.303, P  = 0.026) and total coronary revascularization (aHR: 1.199; 95% CI: 1.037-1.388, P  = 0.014) at 5 years. The results were consistent at the 2-year endpoints. In patients with CPCI, BP-DES use was associated with significantly higher MACE rates at 5 years (aHR: 1.256; 95% CI: 1.078-1.462, P  = 0.003) and total coronary revascularization (aHR: 1.257; 95% CI: 1.052-1.502, P  = 0.012) compared with that of DP-DES, but there was a similar risk at 2 years. However, BP-DES had comparable safety and efficacy profiles including MACE and total coronary revascularization compared with DP-DES in patients with non-CPCI at 2 and 5 years. CONCLUSIONS Patients underwent CPCI remained at a higher risk of mid- to long-term adverse events regardless of the stent type. The effect of BP-DES compared with DP-DES on outcomes was similar in CPCI and non-CPCI patients at 2 years but had inconsistent effects at the 5-year clinical endpoints.

Objective:To analyze the indication and status of early use of analgesic, sedative and antiepileptic drugs of patients with traumatic brain injury (TBI) admitted to the neurological intensive care unit (NICU).Methods:A questionnaire covering hospital basic characteristics, prehospital and emergency care, inpatient treatment, neurocritical care and rehabilitation were used to survey NICU of 37 hospitals in 18 municipalities or provinces from the Chinese registry of the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) by Web or Email. The indications for admission to the NICU, categories and frequency of early use of analgesic and sedative drugs, and categories, frequency and indications of early use of antiepileptic drugs were analyzed.Results:Glasgow coma scale (GCS)≤8 points in patients with TBI and post-operation of TBI were the main indications for admission in 30 NICU (81.1%) and 24 NICU (64.9%), respectively. When admitting patients with a GCS of 9-12 points or 13-15 points, most NICU gave more considerations to the combined other risk factors. In terms of the early use of analgesics and sedatives, fentanyl was routinely used for analgesia (i.e., use frequency for 70%-100%) in 13 NICU (35.1%), and midazolam and alpha-2 agonists were routinely used for sedation in 24 NICU (64.9%) and 18 NICU (48.6%), respectively. Regarding the early use of antiepileptic drugs, sodium valproate was routinely used in 35 NICU (94.6%). Moreover, seizures within 2 hours after injury, penetrating TBI and cortical contusion were indications for routine application of antiepileptic drugs in 35 NICU (94.6%), 21 NICU (56.8%) and 20 NICU (54.1%), respectively.Conclusions:Severe TBI and post-operation of TBI are the main indications for admission to the NICU, while the combination of other risk factors will be considered when admitting patients with moderate or mild TBI. For TBI patients admitted to NICU, fentanyl, midazolam and sodium valproate are the most commonly used analgesic, sedative, and antiepileptic drugs in the early stage. Seizures within 2 hours after injury, penetrating TBI and cortical contusion are the main indications for antiepileptic drug use.

Objective:To explore the pathogenic genes, clinical characteristics and treatment follow-up of children with congenital long QT syndrome (LQTS).Methods:Clinical data of 20 cases diagnosed with congenital LQTS and underwent gene testing from April 15, 2011 to April 15, 2021 in Department of Pediatric Cardiology, Shandong Provincial Hospital Affiliated to Shandong University were retrospectively collected and analyzed using independent sample t-test and Fisher′ s exact probability method. Results:LQTS-related gene mutations were detected in all the 20 cases, and pathogenic or suspected pathogenic mutations were identified in 18 cases (90.0%). Five LQTS mutation genes were discovered, including KCNQ1, KCNH2, SCN5A, CACNA1C and AKAP9.Eighteen cases (90.0%) had positive symptoms, and 13 cases (65.0%) had definite inducements.The inducement of symptoms in children with LQTS type 1(LQT1) was related to exercise, the causes of syncope in LQT1 and Jervell-Lange-Nielsen syndrome type 1 (JLNS1) with complex heterozygous mutations were exercise or emotional agitation; the causes of syncope in LQTS type 2 (LQT2) were unrelated to exercise; severe exercise in LQTS type 3 (LQT3) resulted in symptoms; and seizure in LQTS type 8 (LQT8) was non-induced.The corrected QT(QTc) interval of 20 cases was (553.1±66.6) ms, with a range of 460-707 ms, among which 17 cases showed QTc≥480 ms.The electrocardiogram(ECG) manifestations of children with various types of LQTS were different.There was no significant difference in QTc between different genders, or between children with syncope and those without syncope (all P>0.05). The follow-up time was (3.4±2.3) years, ranging from 0 to 8.3 years.Seventeen children received treatment[beta blockers and implantable cardiovertor-defibrillator(ICD)] and 3 cases did not.By the end of the follow-up, 1 child died, 19 cases survived, and 2 cases of the surviving children lost consciousness. Conclusions:There is a high consistency between genetic diagnosis and clinical diagnosis of congenital LQTS.The positive rate of gene detection is 90.0%.The clinical manifestations and ECG characteristics vary with genotypes.Beta blockers are protective.ICD therapy can prevent sudden cardiac death when oral medication does not respond.

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.

Objective: To observe the safety and impact of short-term anticoagulant therapy on prognosis after selective percutaneous coronary intervention (PCI) in patients with coronary artery disease. Methods: From January 2013 to December 2013, 9 769 consecutive patients underwent selective PCI in Fuwai Hospital were retrospectively included in this study. Patients were divided into two groups, including non-post-PCI anticoagulant therapy group and low-dose and short-time post-PCI anticoagulant therapy group (enoxaparin 0.4 ml/12 h or fondaparinux 2.5 mg/day by subcutaneous injection for 2-3 days after PCI). All patients were evaluated at 30 days, 180 days and 12 months for major adverse coronary and cerebral events (MACCE) including all-cause death, myocardial infarction, revascularization and stroke as well as in-stent thrombosis and bleeding events. Data from 1 755 pairs of patients were analysis after propensity score matching. The clinical outcomes were compared between groups by using Kaplan-Meier survival analysis before and after propensity score matching. Multivariable Cox analysis was used to define the impact and determinants of post-PCI anticoagulation on clinical outcomes. Results: one thousand seven hundred and fifty-five (18.0%) patients didn′t receive post-PCI anticoagulation and 8 014 (82.0%) patients received post-PCI anticoagulation, 5 666 (58.0%) patients received enoxaparin and 2 348 (24.0%) patients received fondaparinux. Patients were younger and incidence of female patients was less, incidence of renal dysfunction and acute coronary syndrome were higher in low-dose and short-time post-PCI anticoagulant therapy group than in non-post-PCI anticoagulation group (all P<0.05). Similarly, patients with post-PCI anticoagulation were associated with more left main coronary artery lesion and branch lesion (P<0.05). Post-PCI anticoagulation patients were associated with less trans-femoral process, more drug-eluting stents implantation and less simple balloon dilatation (all P<0.05). Nine thousand seven hundred and seventeen (99.5%) patients completed 2 years follow up. Post-PCI anticoagulation patients had significantly lower 30-day all-cause death (0.05% (4 cases) vs. 0.46% (8 cases), P<0.001) and stroke (0 vs. 0.11% (2 cases), P=0.003), lower 180-day all-cause death (0.17% (14 cases) vs. 0.57% (10 cases), P=0.002), revascularization (2.07% (166 cases) vs. 3.71% (65 cases), P<0.001) and MACCE (3.49% (280 cases) vs. 5.47% (96 cases), P<0.001), lower 2-year revascularization (7.61% (610 cases) vs. 12.84% (225 cases), P<0.001) and MACCE (10.92 (875 cases) vs. 16.01% (281 cases), P<0.001). Multivariable Cox regression analysis showed that post-PCI anticoagulant therapy was an independent protective factor of 30-day (HR=0.17, 95%CI 0.05-0.62, P=0.007), 180-day all-cause death (HR=0.37, 95%CI 0.16-0.87, P=0.023) and MACCE (HR=0.74, 95%CI 0.58-0.94, P=0.013), 2-year MACCE (HR=0.71, 95%CI 0.62-0.81, P<0.001). After propensity score matching, post-PCI anticoagulation therapy remained as an independent protective factor of 30-day all-cause death (HR=0.11, 95%CI 0.01-0.92, P=0.042) and 2-year MACCE (HR=0.81, 95%CI 0.68-0.96, P=0.015). Conclusions Low-dose and short-time post-PCI anticoagulant therapy may decrease 30-day all-cause death, 180-day all-cause death and MACCE and 2-year MACCE, and meanwhile this option does not increase bleeding risk in patients underwent selective PCI.

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.

Objective: To evaluate the predictive value of GRACE discharge score on the long-term out-of-hospital coronary thrombotic events (CTE) after percutaneous coronary intervention (PCI) with drug-eluting stents. Methods: Present study was a prospective, observational, single center study. 10 724 consecutive patients underwent PCI in Fuwai Hospital between January and December 2013 were included, stents were implanted with conventional method. After PCI, patients were prescribed aspirin 100 mg once daily indefinitely, and either clopidogrel 75 mg once daily or ticagrelor 90 mg twice daily for at least 1 year. A total of 9 782 patients were included in the final analysis after excluding patients who did not undergo successful stent implantation, who were not discharged on dual anti-platelet therapy (DAPT), who only underwent bare-metal stents, who experienced in-hospital major bleeding, stent thrombosis, myocardial infarction (MI) or death,and who lost follow up. Clinical data were collected from all patients. 9 543 patients with complete baseline data were further analyzed for risk stratification and predictive value of GRACE discharge score. CTE was defined as stent thrombosis or spontaneous myocardial infarction. All patients were followed through Fuwai Hospital Follow-up Center, and evaluated either by phone, letter, or clinic visits or at 1, 6, 12 and 24 months after PCI. Risk stratification was performed according to the GRACE discharge score, and the predictive value of the GRACE discharge score was assessed using the receiver operating characteristic (ROC) curve. Results: After 2 years follow-up, there were 95 CTE among the 9 782 patients. The patients were divided into 2 groups according to the presence or absence of CTE: CTE group (95 cases) and no CTE group (9 687 cases). GRACE discharge score was significantly higher in CTE group than no CTE group (82.98±27.58 vs. 75.51±22.46, t=-2.57, P=0.012). According to risk stratification of GRACE discharge score, the patients were divided into low-risk (≤88) group (n=6 902), moderate-risk (89-118) (n=2 988) and high-risk (>118) (n=343) groups. As compared to the low-risk group, CTE risk in moderate- and high-risk groups was 1.59 times (HR 1.59, 95%CI 1.01-2.52, P=0.046) and 3.89 times higher (HR 3.89, 95%CI 1.98-7.65, P<0.001), respectively. Further analysis showed that the GRACE score had predictive value in the total cohort for CTE (area under the receiver operating characteristic (AUROC) 0.576, 95%CI 0.512-0.640, P=0.012) and in the acute coronary syndromes(ACS) subgroup for CTE: (AUROC 0.594, 95%CI 0.509-0.680, P=0.019), but not in the non-ACS subgroup: (AUROC 0.561, 95%CI 0.466-0.657, P=0.187). Conclusion GRACE discharge score can predict the long-term out-of-hospital CTE in patients undergoing PCI with drug-eluting stents and treated with DAPT, and patients can be stratified into the low-, moderate- and high-risk groups of CTE by the GRACE discharge score.

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/m², 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.

The issue on the acupuncture clinical service mode has been early proposed by the scholars. The acupuncture clinical service mode is still existed as the department of acupuncture in TCM hospital nowadays. But this pattern has brought the inconvenience and issues between physicians and patients. In the study, through reviewing briefly the history of acupuncture hospital since the foundation of the People's Republic of China, the authors explained why taking the Hospital of Acupuncture and Moxibustion, China Academy of Chinese Medical Sciences (CACMS) as the object. By integrating the relevant achievements of the scholars on the study of acupuncture hospital, the historical development of acupuncture-moxibustion hospital was reviewed. By comparing with the development mode of TCM hospital, the differences were generalized between the two hospitals in terms of the purpose of hospital establishment, the development mode of treatment, education and research, modernization mode, the relationship with western medicine and the hospital scale. It was analyzed by the authors that the development characteristics of acupuncture-moxibustion hospital were determined by the accidental and the inevitable factors. By the comprehensive analysis, the enlightenments to the future development of acupuncture-moxibustion hospital were explored.
