Abstract
A new alkaloid (3), together with three known compounds, were isolated from the Thespesia populnea endophytic fungus TM-Y1-1. Their structures were elucidated by extensive spectroscopic methods. The absolute configuration of compound 3 was determined for the first time by ECD calculation and DP4+ analysis. All compounds were evaluated for antimicrobial activity. The results showed that compounds 1 and 2 both exhibited moderate inhibitory activity against banana Colletotrichum gloeosporioides with MIC value of 31.25 μg/ml.

Abstract
Objective: To investigate the clinical application value of the modified Lee grading system (abbreviated as the modified system) in evaluating the degree of intervertebral foraminal stenosis(IFS) in patients with foraminal lumbar disc herniations(FLDH). Methods: MRI data of 83 patients with FLDH-IFS (34 patients in the operation group and 49 patients in the conservative group) in Yantai Affiliated Hospital of Binzhou Medical University and Yantai Yantaishan Hospital from March 2018 to February 2021 were retrospectively collected. There were 43 males and 40 females, ranged from 34 to 82 years old, with an average of (61±10) years. MRI images of selected patients were independently evaluated and recorded by two radiologists in a blind method, using both the Lee grading system (abbreviated as Lee system) and the modified system, respectively and each method was evaluated twice. The difference between the evaluation level of the two systems, and the agreement of observer assessments of the two systems were compared, and the correlation between the evaluation level of the two grading systems and the clinical treatment modalities was analyzed. Results: The percentage of nongrade 3 (grade 0-2) patients with effective conservative treatment according to the two grading systems was 94.6 % (139/147) and 64.2 % (170/265), respectively. The percentage of grade 3 patients requiring surgical treatment according to the two grading systems was 69.2 % (128/185) and 61.2 % (41/67), respectively. There was a statistically significant difference between the evaluation levels of the modified system and the Lee system (Z=-5.16, P=0.001). In the Lee system, the intra-observer observation consistency Kappa values of the two radiologists were 0.735 and 0.542, respectively, which were highly and moderately consistent; and the inter-observer observation consistency Kappa values were 0.426-0.521, which were moderate consistency. In the modified system, the intra-observer consistency Kappa values of the two radiologists were 0.900 and 0.921, respectively, and the consistency was almost completely consistent; and the inter-observer consistency Kappa values were 0.783-0.861, which were highly consistent or almost completely consistent. Lee system and clinical treatment modalities was correlative (rs=0.39,P<0.001), and modified system and clinical treatment modalities was correlative (rs=0.61,P<0.001). Conclusion: According to FLDH-IFS, the modified system can comprehensively and accurately grade, with high reliability and reproducibility. The evaluation level has a more significant correlation with clinical treatment modalities.

Abstract
Objective: To investigate the clinical and pathological features of salivary secretory carcinoma (SSC). Methods: Ten cases of SSC confirmed in the Department of Pathology,Capital Medical University School of Stomatology from January 2014 to December 2021 were retrospectively included, including 5 males and 5 females, with a median age of 46.5 years. The microscopic morphology, immunophenotype, special staining and clinical follow-up of 10 cases of salivary secretory carcinoma were observed. Ten patients were tested with S-100, vimentin, mammaglobin, Dog-1, p63 and Ki-67, 9 cases with cytokeratin (CK) 8/18, 8 with CK7, 6 with calponin, 5 with smooth muscle actin (SMA) and GCDFP15, 4 with CK5/6 and 1 with SOX10. The ETV6-NTRK3 fusion gene was detected by fluorescence in situ hybridization. Results: Seven of the 10 SSC were located in the parotid gland and 3 were located in the cheeks. Histomorphology showed solid, papillary-cystic, follicular, microcystic, and macrocystic types. In 7 cases, tumor cells were dominated by single arrangement type, while certain mixed arrangements existed in some areas. The cytoplasm of the tumor cells was rich in eosinophilic, fine granular or vacuolar shapes, and clear cytoplasm was seen in 2 cases. The nuclei were mostly oval-shaped vesicular nuclei, with nucleoli in the center. Immunohistochemistry showed CK7 (8/8) positive, CK8/18 (9/9) positive, S-100 (10/10) positive, vimentin (5/10) positive, (4/10) partially positive and (1/10) less partially positive, mammaglobin (7/10) positive, (1/10) partially positive and (2/10) some individual cells positive, Dog-1 (10/10) negative, CK5/6 (4/4) negative, p63 (7/10) negative and (3/10) partially positive, SMA (5/5) negative, calponin (6/6) negative, and Ki-67 index was 5%-20%. Secretions of 5 cases showed periodic acid-Schiff (PAS) and PAS with diastase (PAS-D) staining positive. All 10 cases showed ETV6-NTRK3 fusion positive. Six cases were successfully followed up for 32-91 months, of which 2 cases recurred after 28 and 74 months and underwent surgical resection again. All cases followed up are alive and disease-free. Conclusions: The salivary secretory carcinoma is a rare low-grade malignant tumor. In certain cases, morphology is atypical and mammaglobin is immunohistochemically positive in only individual tumor cells. Therefore, the diagnosis should be supported with morphology, immunohistochemical staining, and molecular feature preferably.

Abstract
1. The aim of this study was to explore the effects of acute heat stress on serum hormone levels and the expression of genes and proteins related to the unfolded protein response (UPR) pathway and apoptotic process in the liver of broilers.2. A total of 144 Arbor Acres broilers (35-d-old) were randomly allocated to 4 different environmental-controlled chambers for acute heat exposure. The temperature of the 4 environmental chambers was adjusted to 26°C (control), 29°C, 32°C, and 35°C within 1 h, respectively. The blood and liver samples were collected after 6 h of constant heat exposure at set temperatures.3. The results showed that 6 h of acute heat stress increased serum hormone levels and up-regulated the expression of heat shock protein. The endoplasmic reticulum (ER) stress markers, GRP78 and GRP94, in the liver of broilers were significantly upregulated at the mRNA and protein levels. The PERK, IRE1, and XBP1 genes, which are involved in the unfolded protein response signalling, were significantly up-regulated at the mRNA levels. However, other pro-apoptotic genes showed no significant changes in the liver of broiler chickens in all groups except for upregulation of the anti-apoptotic gene BCL-xl.4. The results suggested that broilers have tolerance to acute heat stress to a certain extent. The UPR activation can alleviate ER stress and further prevent apoptosis in the liver of broilers under short-term exposure to high ambient temperatures.

Abstract
Objective: To investigate the Helicobacter pylori (H. pylori) eradication rate and improvement of dyspepsia in patients who were newly diagnosed with H. pylori infection and dyspepsia and treated by bismuth-containing quadruple therapy followed by Jing-Hua-Wei-Kang(JHWK). Methods: Patients who were newly diagnosed with dyspepsia and H. pylori infection and treated in 16 medical centers in China between December 1, 2017 and September 30, 2019 were randomly divided into two groups. The experimental group received bismuth-containing quadruple therapy (esomeprazole+amoxicillin+furazolidone+colloidal bismuth pectin capsule, 14 days), followed by JHWK (30 days), and the course of treatment was 44 days in total. In the control group, the administration regimen was bismuth-containing quadruple therapy (esomeprazole+amoxicillin+furazolidone+colloidal bismuth pectin capsule, 14 days). The main outcome measure was H. pylori eradication rate, while the secondary outcome measures were dyspepsia symptom changes and adverse events during the treatment and the 1st month after treatment. Results: A total of 1 054 patients were included in the study. There were 522 cases enrolled in the experimental group, including 224(42.91%) men and 298(57.09%) women, and the age was 53(26, 73) years old; 532 cases enrolled in the control group, including 221(41.54%) men and 311(58.46%) women, and the age was 46(22, 71) years old. Based on PP analysis, it was found that the H. pylori eradication rate in the experimental group was significantly higher than those in the control group (93.85% vs 87.88%, P=0.001). In the group of all enrolled patients, the symptom dyspepsia after H. pylori eradication was significantly improved compared with that before treatment [4(4, 7) vs 15(10, 22), P<0.001], so was the superior and middle abdominal pain [1(1, 4) vs 4(1, 8), P<0.001], the postprandial fullness [1(1, 4) vs 4(4, 9), P<0.001], the early satiety [1(1, 1) vs 4(1, 4), P<0.001], and the heartburn [1(1, 1) vs 1(1, 4), P<0.001]. The symptom dyspepsia after treatment was significantly improved compared with that before treatment in the experimental, the control groups, the successful and the unsuccessful H. pylori eradication groups. The superior and middle abdominal pain after treatment was signifcantly improved than that before treatment [1(1, 2) vs 1(1, 4), P<0.001], so were the postprandial fullness [1(1, 3) vs 1(1, 4), P=0.002] and the dyspepsia[4(4, 7) VS 7(4, 10), P<0.001]. There was no statistically significant difference in the incidence of adverse events between the experimental group and the control group (1.34% vs 0.38%, P=0.09). Conclusions: Compared with bismuth-containing quadruple therapy, bismuth-containing quadruple therapy followed by JHWK significantly improves the H. pylori eradication rate without increasing the incidence of adverse events. H. pylori eradication therapy can improve symptoms of patients with H. pylori infection and dyspepsia.

Abstract
Objective: To investigate the impact of metabolic syndrome (MS) and its individual components on long-term prognosis of patients undergoing percutaneous coronary intervention(PCI). Methods: Patients who underwent PCI in Fuwai Hospital in 2013 were enrolled and divided to two groups: with MS and without MS. The primary endpoint of 2-year follow-up was major adverse cardiovascular events (MACE), including death, myocardial infarction, and repeat revascularization. Results: Of the 10 422 PCI patients, there were 5 656 (54.27%) without MS and 4 766 (45.73%) with MS. Patients in the MS group were younger, tended to be male and had more comorbidities. There were no significant differences between the two groups in the proportion of drug-coated stents and the success rate of interventional therapy. The 2-year follow-up showed that the incidence of MACE in the MS group was significantly higher than that in the MS-free group (12.0% vs 10.0%, P<0.001), which was mainly due to the significantly higher revascularization rate in the MS group than in the non-MS group (9.5% vs 7.9%, P=0.003). Cox's regression analysis showed that MS was an independent risk factor for MACE. In MS component analysis, abnormal glucose metabolism was an independent risk factor for MACE events. Conclusions: Among the patients undergoing PCI, the incidence of MACE in patients with MS is significantly higher than that in patients without MS, and MS was an independent risk factor for MACE. In addition, hyperglycemia is an independent predictor for MACE.

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 understand the status of child health services by primary medical institutions in less developed areas in Sichuan province and provide evidence for the development of health policy for poverty alleviation. Methods: Annual child health records in the primary medical institutions selected through multistage stratified sampling in 21 prefectures in Sichuan were extracted during 2014-2018. Field survey and telephone interview were used to evaluate the performance of child health services provided and the child guardian's satisfaction degree. Sample descriptive statistics, pair sample t-test, χ(2) test, trend χ(2) test, Pearson correlation analysis were used for statistical analysis. Results: Except child system management rate, the other indicators reflecting the status of child health service in less developed areas in Sichuan were on rise (P<0.05), and close to average level of whole province in 2018. Except child system management rate, the other indicators reflecting the status of child health management in less developed counties were lower than those in developed counties in Sichuan, most differences were significant (P<0.05). Except child health management rate of traditional Chinese medicine, the other indicators reflecting the status of child health management in less developed counties were higher than those in poverty-stricken counties in Sichuan, most differences were not significant (P≥0.05). Except child systematic management rate, the gap in indicators reflecting child health service status between less developed area and developed area was in reduction, some difference were significant (P<0.05). The child guardian satisfaction degree was associated with true child health management rates (r=0.947, P=0.015), and child health management rate of traditional Chinese medicine (r=0.996, P<0.001). Conclusions: Some achievements have been made in child health services provided by primary medical institutions in less developed areas in Sichuan. To achieve the 2020 poverty alleviation goal, it is necessary to take measures to increase input and improve service level.

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
Objective: To investigate the possible mechanism of doxycycline inhibiting paraquat-induced pulmonary fibrosis and provide a theoretical basis for its clinical application. Methods: Human lung fibroblast HFL1 cells were selected as the research object in the cell group. Divided into blank group, paraquat group, paraquat+doxycycline group. The expression of TGF-β1, a-SMA, Smad3 and Smad2 protein was detected by ELISA using 40 ml of paraquat 40 umol/L and 3 mg/L of oleic acid 10 mg/L. In the animal group, 120 healthy and clean SD rats were randomly divided into three groups: blank group, paraquat group, paraquat+doxycycline group. The expression of TGF-β1, a-SMA, Smad3 and Smad2 protein in lung tissue of mice at 1 day, 3 days, 7 days, 14 days and 21 days was detected by Elisa method. The expression of TGF-β1, a-SMA, Smad3 and Smad2 protein in lung tissue of 21-day mice was detected by Western Blotting. The pathological changes of lung tissue were observed by HE staining for 1 day, 3 days, 7 days, 14 days and 21 days. Results: In the cell group experiment, the expression of TGF-β1, a-SMA, Smad3 and Smad2 protein increased gradually with paraquat in the paraquat group, and the expression of TGF-β1, a-SMA, Smad3 and Smad2 protein was significantly higher than that in the blank group. The difference was statistically significant (P<0.05) . The expressions of TGF-β1, a-SMA, Smad3 and Smad2 in the paraquat+doxycycline group were significantly lower than those in the paraquat group, but still higher than the blank group, the difference was statistically significant (P<0.05) . Conclusion: Doxycycline inhibits paraquat-induced pulmonary fibrosis by inhibiting the expression of TGF-β1, a-SMA and Smad3, Smad2 proteins.

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
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.

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

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

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

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

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

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

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

Abstract
BACKGROUND A previous study provided evidence for a genetic association between PPP2CA on 5q31.1 and systemic lupus erythematosus (SLE) across multi-ancestral cohorts, but failed to find significant evidence for an association in the Han Chinese population. OBJECTIVES To explore the association between this locus and SLE using data from our previously published genome-wide association study (GWAS). METHODS Single-nucleotide polymorphisms (SNPs) rs7726414 and rs244689 (near TCF7 and PPP2CA in 5q31.1) were selected as candidate independent associations from a large-scale study in a Han Chinese population consisting of 1047 cases and 1205 controls. Subsequently, 3509 cases and 8246 controls were genotyped in two further replication studies. We then investigated the SNPs' associations with SLE subphenotypes and gene expression in peripheral blood mononuclear cells. RESULTS Highly significant associations with SLE in the Han Chinese population were detected for SNPs rs7726414 and rs244689 by combining the genotype data from our previous GWAS and two independent replication cohorts. Further conditional analyses indicated that these two SNPs contribute to disease susceptibility independently. A significant association with SLE, age at diagnosis < 20 years, was found for rs7726414 (P = 0·001). The expression levels of TCF7 and PPP2CA messenger RNA in patients with SLE were significantly decreased compared with those in healthy controls. CONCLUSIONS This study found evidence for multiple associations with SLE in 5q31.1 at genome-wide levels of significance for the first time in a Han Chinese population, in a combined genotype dataset. These findings suggest that variants in the 5q31.1 locus not only provide novel insights into the genetic architecture of SLE, but also contribute to the complex subphenotypes of SLE.

Abstract
Combinatorial metrology has evolved as a useful approach to rapidly determine the composition-structure-property relationships for solid solution systems in a far more efficient way than the traditional one composition at a time approach. The success of this method applied in thermoelectric (TE) research relies on screening tools to evaluate the TE properties for a combinatorial library. We report here on a thermoelectric screening tool capable of performing temperature dependent measurement of the Seebeck coefficient and electrical resistivity from 300 K to 800 K. The validity of the apparatus is demonstrated by screening the power factor of a filled skutterudite combinatorial film at room temperature and at elevated temperatures as well. The accuracy of the measurement is verified using the low temperature Seebeck coefficient Standard Reference Material (NIST SRM 3451) and a heavily doped SiGe specimen for high temperature comparison. Several important parameters, such as measurement atmosphere, film substrate, and probe configuration, are identified that directly affect the Seebeck coefficient measurement in this and other similar apparatus.

Abstract
We report a home-made combustion apparatus for study of pressure-dependent laminar premixed flames with tunable vacuum ultraviolet photoionization mass spectrometry. The instrument consists of a flame chamber, a photoionization chamber with a single-stage sampling system, an ion transfer/storage system, and an orthogonal-acceleration reflectron time-of-flight mass spectrometer. Preliminary results of fuel-rich C(2)H(4)/O(2)/Ar flames at pressures of 30, 150, and 760 Torr have been obtained with this instrument. Compared to previous instruments [T. A. Cool, A. McIlroy, F. Qi, P. R. Westmoreland, L. Poisson, D. S. Peterka, and M. Ahmed, Rev. Sci. Instrum. 76, 094102 (2005); F. Qi, R. Yang, B. Yang, C. Q. Huang, L. X. Wei, J. Wang, L. S. Sheng, and Y. W. Zhang, Rev. Sci. Instrum. 77, 084101 (2006)], performances of the new apparatus have higher mass resolution (~3500 at m/z = 40), better detection limit (<1 ppm), and broader dynamic range (better than 5 order of magnitude).

Abstract
The structural, electronic and magnetic properties of BiSb nanoribbons (BSNRs) with different widths and edge configurations are investigated via the first-principles pseudopotential method. It is found that the pristine BSNRs with armchair edges (ABSNRs) are semiconductors and the band gaps exhibit a width dependent odd-even oscillation. In contrast, the pristine BSNRs with zigzag edges (ZBSNRs) are found to be metallic. When all the edge atoms are passivated by hydrogen, both the ABSNRs and ZBSNRs become semiconducting and the corresponding band gaps decrease monotonically with the increasing width. If, however, the edge atoms are partially passivated, the ABSNRs can be either semiconducting or metallic. Moreover, local magnetism appears when all the edge Sb atoms are passivated and there are one or more unsaturated Bi atoms. Using the nonequilibrium Green's function (NEGF) approach, we find that all the investigated odd-numbered ABSNRs have almost the same peak value of the power factor around the Fermi level. This is not the case for the even-numbered ABSNRs, where the peaks are twice that of when they are n-type doped. Our calculations indicate that BSNRs can have a very high room temperature figure of merit (ZT value), which makes them very promising candidates for thermoelectric applications.

Abstract
BACKGROUND Allergic rhinitis (AR) is one of the most common diseases caused by the combined effects of intrinsic factors (susceptibility genes and immunological status) and the external environment. Analyses of ascendant family history of atopic disease suggest that AR and atopic dermatitis might share a similar genetic background. OBJECTIVE To conduct a case-control study in a Chinese Han population to evaluate the potential influence of single nucleotide polymorphisms (SNPs) at FLG, 5q22.1, 11q13.5, 14q11.2 and 20q13.33 on AR. METHODS Ten SNPs--rs11204971 and rs3126085 at FLG, rs10067777, rs7701890, rs13360927, and rs13361382 at 5q22.1, rs6010620 at 20q13.33, rs7936562 and rs7124842 at 11q13.5, and rs4982958 at 14q11.2 were genotyped in 363 cases and 668 controls using the Sequenom MassArray system. Data were analyzed with PLINK 1.07 software. RESULTS The T allele of rs4982958 at 14q11.2 was observed to be significantly associated with AR (P = .002, OR = 0.73, P(Bonferront) = .02). Genotype-based association testing revealed that the recessive model might provide the best fit for rs4982958 (P(Bonferroni) = .01). In subphenotype analyses, the rs4982958 T allele was also significantly associated with persistent AR (P = .01) and more than 2 positive skin prick tests (P = .038). CONCLUSION We identified a novel susceptibility locus 14q11.2 for AR that might bear candidate genes conferring susceptibility to AR and affecting disease phenotypes.

Abstract
Using (106±4)×10⁻⁶ ψ(3686) events accumulated with the BESIII detector at the BEPCII e⁺e⁻ collider, we present the first measurement of decays of χ(c1) to vector meson pairs φφ, ωω, and ωφ. The branching fractions are measured to be (4.4±0.3±0.5)×10⁻⁴, (6.0±0.3±0.7)×10⁻⁴, and (2.2±0.6±0.2)×10⁻⁵, for χ(c1)→φφ, ωω, and ωφ, respectively, which indicates that the hadron helicity selection rule is significantly violated in χ(cJ) decays. In addition, the measurement of χ(cJ)→ωφ provides the first indication of the rate of doubly OZI-suppressed χ(cJ) decay. Finally, we present improved measurements for the branching fractions of χ(c0) and χ(c2) to vector meson pairs.

Abstract
BACKGROUND Accumulating evidence indicates that psoriasis is associated with increased risk of overweight and obesity. However, few studies have investigated this relationship in Chinese Han population. OBJECTIVE The aim of this study was to explore the relationship between overweight/obesity and psoriasis and to evaluate the overweight/obesity effect on the clinical features of psoriasis in Chinese Han population. METHODS A hospital-based study was conducted, which involved in 4452 patients and 1166 controls of Chinese Han through epidemiological investigation. Controls used in the study were individuals without psoriasis from health examination centre, and other skin disease patients from outpatient department. RESULTS Compared with the control group, a significantly greater prevalence of overweight and obesity was observed in psoriasis patients. The estimated ORs were 1.301 (95% CI, 1.105-1.531) and 1.680 (95% CI, 1.134-2.491) respectively. The disease severity of psoriasis measured by psoriasis area and severity index (PASI) was statistically correlated with body mass index (BMI) (r = 0.184, P < 0.01). Moreover, a high proportion of overweight patients had affected hands or/and feet, buttocks, trunk, legs, arms and arthritis (P < 0.01). CONCLUSIONS Our study suggested that psoriatic patients have a higher prevalence of overweight and obesity compared with non-psoriatic patients in Chinese Han population. Overweight and obesity has different risk effect on severity and manifestations of psoriasis and might be useful for better evaluating psoriasis clinically.

Abstract
With a sample of (225.2±2.8)×10(6) J/ψ events registered in the BESIII detector, J/ψ→γπ(+)π(-)η(') is studied using two η(') decay modes: η(')→π(+)π(-)η and η(')→γρ(0). The X(1835), which was previously observed by BESII, is confirmed with a statistical significance that is larger than 20σ. In addition, in the π(+)π(-)η(') invariant-mass spectrum, the X(2120) and the X(2370), are observed with statistical significances larger than 7.2σ and 6.4σ, respectively. For the X(1835), the angular distribution of the radiative photon is consistent with expectations for a pseudoscalar.

Abstract
The decays ψ'→γπ(0), γη and γη' are studied using data collected with the BESIII detector at the BEPCII e(+)e(-) collider. The processes ψ'→γπ(0) and ψ'→γη are observed for the first time with signal significances of 4.6σ and 4.3σ, respectively. The branching fractions are determined to be B(ψ'→γπ(0))=(1.58±0.40±0.13)×10(-6), B(ψ'→γη)=(1.38±0.48±0.09)×10(-6), and B(ψ'→γη')=(126±3±8)×10(-6), where the first errors are statistical and the second ones systematic.

Abstract
The aim of this study is to investigate the relationship between thermochemotherapy-induced apoptosis and the expressions of the Bcl-2 and Bax proteins in maxillofacial squamous cell carcinomas. Fifteen patients with maxillofacial squamous cell carcinomas were treated with microwave hyperthermia (43 °C for 40 min) following the intravenous injection of pingyangmycin (Bleomycin A5 Hydrochloride for Injection) (8 mg). Subsequently, the tumors were surgically resected. The terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick-end labeling method was used to assess the apoptosis in the carcinoma cells, and immunohistochemistry was performed using the streptavidin-peroxidase method to determine the expression levels of the Bcl-2 and Bax proteins, and quantitative analysis was employed. The number of apoptotic cells increased markedly (P < 0.001). The protein expression of Bcl-2 was downregulated (P < 0.001), while that of Bax was markedly upregulated (P < 0.001). Thermochemotherapy induces apoptosis in maxillofacial squamous cell carcinoma cells by downregulating the protein expression of Bcl-2 and upregulating that of Bax.

Abstract
We present measurements of the charmonium state h(c)(1P(1)) made with 106x10(6) psi' events collected by BESIII at BEPCII. Clear signals are observed for psi'-->pi0 h(c) with and without the subsequent radiative decay h(c)-->gamma eta(c). First measurements of the absolute branching ratios B(psi'-->pi0 h(c)) = (8.4+/-1.3+/-1.0) x 10(-4) and B(h(c)-->gamma eta(c)) = (54.3+/-6.7+/-5.2)% are presented. A statistics-limited determination of the previously unmeasured h(c) width leads to an upper limit Gamma(h(c))<1.44 MeV (90% confidence). Measurements of M(h(c)) = 3525.40+/-0.13+/-0.18 MeV/c2 and B(psi'-->pi0 h(c)) x B(h(c)-->gamma eta(c)) = (4.58+/-0.40+/-0.50) x 10(-4) are consistent with previous results.

Abstract
Interactions of TBP-interacting protein (TIP26), TBP, and TFB from a hyperthermophilic archaeon Thermococcus kodakaraensis KOD1 with TATA-DNA were examined by electrophoretic mobility shift assay. Tk-TFB formed a ternary complex with Tk-TBP and TATA-DNA. Tk-TIP26 did not inhibit the formation of this ternary complex, but interacted with it to form a TIP26/TFB/TBP/DNA quaternary complex. This interaction is rather weak, and a large excess of Tk-TIP26 over Tk-TBP is required to fully convert the TFB/TBP/DNA ternary complex to the quaternary complex. However, determination of the concentration of Tk-TIP26 and Tk-TBP in KOD1 cells by Western blotting analysis indicated that the concentration of Tk-TIP26 is approximately ten times that of Tk-TBP, suggesting that the quaternary complex might also form in vivo.

Abstract
Tk-trpE and Tk-trpG, the genes that encode the two subunits of anthranilate synthase from the hyperthermophilic archaeon Thermococcus kodakaraensis KOD1, have been expressed independently in Escherichia coli. The anthranilate synthase complex (Tk-AS complex) was obtained by heat-treatment of the mixture of cell-free extracts containing each recombinant protein, Tk-TrpE (alpha subunit) and Tk-TrpG (beta subunit), at 85 degrees C for 10 min. Further purification of Tk-AS complex was carried out by anion-exchange chromatography followed by gel-filtration. Molecular mass estimations from gel-filtration chromatography indicated that Tk-AS complex was a heterodimer (alphabeta). The complex displayed both ammonia- and glutamine-dependent anthranilate synthase activities, and could not utilize asparagine as an ammonia donor. The optimal pH was pH 10.0 and the optimal temperature was 85 degrees C in both cases. Mg2+ was necessary for the anthranilate synthase activity. At 75 degrees C, the K(m) values of chorismate for ammonia- and glutamine-dependent activities were 13.8 and 3.4 microM, respectively. The K(m) value of Mg2+ was 20.5 microM. The K(m) values of glutamine and NH4Cl were 88 microM and 5.6 mM, respectively. Although Tk-TrpE displayed 47.6% similarity with TrpE of Salmonella typhimurium, conserved amino acid residues proven to be essential for inhibition of enzyme activity by L-tryptophan were not present in Tk-TrpE. Namely, residues corresponding to Glu39, Met293, and Cys465 in the enzyme from S. typhimurium were replaced by Arg28, Thr221, and Ala384 in Tk-TrpE. Nevertheless, significant inhibition by L-tryptophan was observed, with K(i) values of 5.25 and 74 microM for ammonia and glutamine-dependent activities, respectively. The inhibition was competitive with respect to chorismate. The results suggest that the amino acid residues involved in the feedback inhibition by L-tryptophan in the case of Tk-AS complex are distinct from previously reported anthranilate synthases.

Abstract
Pyridoxal 5'-phosphate-dependent tryptophan synthase catalyzes the last two reactions of tryptophan biosynthesis, and is comprised of two distinct subunits, alpha and beta. TktrpA and TktrpB, which encode the alpha subunit and beta subunit of tryptophan synthase from a hyperthermophilic archaeon, Thermococcus kodakaraensis KOD1, were independently expressed in Escherichia coli and their protein products were purified. Tryptophan synthase complex (Tk-TS complex), obtained by heat treatment of a mixture of the cell-free extracts containing each subunit, was also purified. Gel-filtration chromatography revealed that Tk-TrpA was a monomer (alpha), Tk-TrpB was a dimer (beta2), and Tk-TS complex was a tetramer (alpha2 beta2). The Tk-TS complex catalyzed the overall alphabeta reaction with a specific activity of 110 micromol Trp per micromol active site per min under its optimal conditions (80 degrees C, pH 8.5). Individual activity of the alpha and beta reactions of the Tk-TS complex were 8.5 micromol indole per micromol active site per min (70 degrees C, pH 7.0) and 119 micromol Trp per micromol active site per min (90 degrees C, pH 7.0), respectively. The low activity of the alpha reaction of the Tk-TS complex indicated that turnover of the beta reaction, namely the consumption of indole, was necessary for efficient progression of the alpha reaction. The alpha and beta reaction activities of independently purified Tk-TrpA and Tk-TrpB were 10-fold lower than the respective activities detected from the Tk-TS complex, indicating that during heat treatment, each subunit was necessary for the other to obtain a proper conformation for high enzyme activity. Tk-TrpA showed only trace activities at all temperatures examined (40-85 degrees C). Tk-TrpB also displayed low levels of activity at temperatures below 70 degrees C. However, Tk-TrpB activity increased at temperatures above 70 degrees C, and eventually at 100 degrees C, reached an equivalent level of activity with the beta reaction activity of Tk-TS complex. Taking into account the results of circular dichroism analyses of the three enzymes, a model is proposed which explains the relationship between structure and activity of the alpha and beta subunits with changes in temperature. This is the first report of an archaeal tryptophan synthase, and the first biochemical analysis of a thermostable tryptophan synthase at high temperature.

Abstract
A serial study of clinical and magnetic stimulation motor evoked potentials (MEP) was accomplished in 44 patients with the acute flaccid paralytic syndrome which occurred in Northern China in 1991. Control data were provided by 70 healthy subjects from the same area. The cases came from the same area where a so-called new "Chinese paralytic syndrome" had been reported. We found the clinical features of these 44 patients to be similar to those of classical Guillain-Barré. Prolongation of MEP latency at 2 sites or on 2 occasions was found in 36 patients of whom 26 showed obvious clinical and electrophysiological recovery within 4-8 weeks. Three cases showed reduced MEP amplitude with normal latency, but in 2 of them the amplitude recovered in 2-8 weeks. Only 2 cases had no response at all time. We think 41 patients (93.7%) had predominant nerve demyelination. The 3 other patients (6.8%) showed axonal degeneration which is within the range found in previous reports of classical Guillain-Barré. We conclude that the acute paralytic syndrome seen in the summer of 1991 in Northern China represents a classical Guillain-Barré syndrome with demyelination of motor and sensory fibers. There is no reason to consider any special nomenclature such as "Chinese paralytic syndrome" or "acute motor axonal neuropathy."

Abstract
N1, P2 and P300 potentials were studied in 20 cases of cerebral infarction and 47 healthy controls with standard technique of auditory event-related potentials. Healthy controls of both sexes, different ages, education levels and cognitive capacity did not show apparent differences in the latency of p300 (P greater than 0.05, respectively). The patient group, however, revealed significant (P less than 0.001) prolongation of latency of P300 (mean = 409.6 +/- 50 ms) as compared with 28 well matched healthy subjects (mean = 337.7 +/- 24 ms). Although there was some decline of amplitude of P300 in the patient group, the difference between the control and patient groups was not significant (P greater than 0.05). There was significant difference in the Cognitive Capacity Screening Examination findings between the control and patient groups (P less than 0.01), but it seemed that the evaluation of latency of cognition-related p300 might be more objective and sensitive (P less than 0.001).

Abstract
Fourteen cervical spondylitic myelopathy (CSM) patients were clinically diagnosed and proved by MRI and surgery. The results of 11 patients showed that 8 (72.7%) had motor evoked potential (MEP) abnormality with prolongation of central motor conduction time (CMCT) in 7, and absence of motor action potentials after C7 stimulation in one. Five of the 11 patients showed normal somatosensory evoked potentials (SEPs) along the same arm. The short term (2-4 weeks) follow-up study in 10 patients showed normalization of the prolonged CMCT in one and reappearance of MEPs with C7 stimulation in another. Non-invasive and painless magnetic transcranial stimulation of the motor pathways is useful in the assessment and management of CSM patients, and is better than electrical stimulation.

Abstract
Five patients from 3 families with Becker muscular dystrophy (BMD) were reported. The main clinical and laboratory findings were in common. Pairs of affected brothers are quite resembled each other. However, there are also some variations among different families. The disease occurred later in the first pair of brothers and was accompanied by macroglossia and red-green color blindness, while the second pair got the disease earlier, which was accompanied by heart impairment. It is interesting that both myogenic and neurogenic changes of EMG can be found in the same patient with BMD in our series.

Abstract
Brainstem auditory evoked potentials (BAEP) were studied on 38 optic myelitis (OM) and 16 of myelopathy with definite abnormal VEP. Forty-two normal subjects were studied for comparison. The results showed that BAEP were abnormal in 42% of the OM and 38% of the latter myelopathy groups. Among the abnormal BAEP 82% showed V wave abnormality, 32% prolongation in I-III or III-V interpeak latency or absence of III wave, and 59% with unilateral lesions. These findings would imply that the lesions were mostly on the white matter and small and localized in character which was compatible with the pathology of MS. 41% of BAEP abnormality in these two groups showed a lesion would be in the brainstem in almost half of these two types of disorders. OM would be most likely a clinical variant type of MS and not a unique disease.

Abstract
Four of 69 cases of small cell lung cancer (SCLC) showed evidence of Lambert-Eaton myasthenic Syndrome (LEMS) were studied neurologically and neurophysiologically in four years. The LEMS appearance were preceded that of SCLC in 3 cases for two years at most. Repeated stimulation of ulnar nerve examination showed diminished amplitude of initial response (0.2-0.9 mv); Amplitude of the response at 3 c/s stimulation for 3 sec was diminished 20-63%. (control 3% decreases-13% increases) but that at 20 c/s stimulation for 10 sec increased 200-800% increases. (control: 20% decreases-56% increases). These findings were important for diagnosis of LEMS. The abnormalities of neurotransmission seems to be due to inadequate release of acetyl choline from nerve terminals at abnormal active zone of Ca++ channels.
