Abstract
Atrial fibrillation (AF), the most prevalent type of sustained cardiac dysrhythmia globally, confers strikingly enhanced risks for cognitive dysfunction, stroke, chronic cardiac failure, and sudden cardiovascular demise. Aggregating studies underscore the crucial roles of inherited determinants in the occurrence and perpetuation of AF. However, due to conspicuous genetic heterogeneity, the inherited defects accounting for AF remain largely indefinite. Here, via whole-genome genotyping with genetic markers and a linkage assay in a family suffering from AF, a new AF-causative locus was located at human chromosome 7p14.2-p14.3, a ~4.89 cM (~4.43-Mb) interval between the markers D7S526 and D7S2250. An exome-wide sequencing assay unveiled that, at the defined locus, the mutation in the TBX20 gene, NM_001077653.2: c.695A>G; p.(His232Arg), was solely co-segregated with AF in the family. Additionally, a Sanger sequencing assay of TBX20 in another family suffering from AF uncovered a novel mutation, NM_001077653.2: c.862G>C; p.(Asp288His). Neither of the two mutations were observed in 600 unrelated control individuals. Functional investigations demonstrated that the two mutations both significantly reduced the transactivation of the target gene KCNH2 (a well-established AF-causing gene) and the ability to bind the promoter of KCNH2, while they had no effect on the nuclear distribution of TBX20. Conclusively, these findings reveal a new AF-causative locus at human chromosome 7p14.2-p14.3 and strongly indicate TBX20 as a novel AF-predisposing gene, shedding light on the mechanism underlying AF and suggesting clinical significance for the allele-specific treatment of AF patients.

Abstract
Objective: To investigate the lifespan of erythrocytes in megaloblastic anemia (MA) patients. Methods: A prospective cohort study analysis. Clinical data from 42 MA patients who were newly diagnosed at the Department of Hematology, Lanzhou University Second Hospital from January 2021 to August 2021 were analyzed, as were control data from 24 healthy volunteers acquired during the same period. The carbon monoxide breath test was used to measure erythrocyte lifespan, and correlations between erythrocyte lifespan and laboratory test indexes before and after treatment were calculated. Statistical analysis included the t-test and Pearson correlation. Results: The mean erythrocyte lifespan in the 42 newly diagnosed MA patients was (49.05±41.60) d, which was significantly shorter than that in the healthy control group [(104.13±42.62) d; t=5.13,P=0.001]. In a vitamin B12-deficient subset of MA patients the mean erythrocyte lifespan was (30.09±15.14) d, and in a folic acid-deficient subgroup it was (72.00±51.44) d, and the difference between these two MA subsets was significant (t=3.73, P=0.001). The mean erythrocyte lifespan after MA treatment was (101.28±33.02) d, which differed significantly from that before MA treatment (t=4.72, P=0.001). In MA patients erythrocyte lifespan was positively correlated with hemoglobin concentration (r=0.373), and negatively correlated with total bilirubin level (r=-0.425), indirect bilirubin level (r=-0.431), and lactate dehydrogenase level (r=-0.504) (all P<0.05). Conclusions: Erythrocyte lifespan was shortened in MA patients, and there was a significant difference between a vitamin B12-deficient group and a folic acid-deficient group. After treatment the erythrocyte lifespan can return to normal. Erythrocyte lifespan is expected to become an informative index for the diagnosis and treatment of MA.

Abstract
Objective: To explore the phonological processes in initial consonants of Putonghua-speaking children in Jiangsu urban areas. Methods: A status survey was applied. From December 2014 to September 2015, a stratified random sampling method was used to select 958 children aged 1 to 6 years with Putonghua as their mother tongue in the urban area of Nanjing, Changzhou, Yangzhou and Xuzhou to examine their phonological performance. Speech samples were collected by the method of picture naming. The children were divided into 9 age groups (1.5-<2.0, 2.0-<2.5, 2.5-<3.0, 2.5-<3.0, 3.0-<3.5, 3.5-<4.0, 4.0-<4.5, 5.0-<6.0, 6.0-<7.0 years). Descriptive analysis method was used to analyze the phonological processes in initial consonants at different age groups. Results: Among the 958 children, there were 482 boys and 476 girls. The age of the children was (3.8±1.4) years. The number of children in the 9 age groups (1.5-<2.0, 2.0-<2.5, 2.5-<3.0, 2.5-<3.0, 3.0-<3.5, 3.5-<4.0, 4.0-<4.5, 5.0-<6.0, 6.0-<7.0 years) is 100, 110, 110, 114, 114, 114, 111, 119, and 66, separately. The process of substitution was found in the speech of 701 children (73.2%), syllable structure simplification was found in 194 children (20.3%), distortion was found in 41 children (4.3%), and assimilation was found in 17 children (1.8%). Among these 4 types of processes, the occurrence of substitution was highest in all the age groups, ranging from 30.3% (20/66) to 94.5% (104/110). The occurrence of syllable structure simplification ranged from 27.3% (30/110) to 91.0% (91/100) in the age groups of 1.5-<3.0 years and 0.9% (1/114) to 7.9% (9/114) in the age groups of 3.0-<7.0 years. The occurrence of distortion ranged from 7.3% (8/110) to 19.1% (21/110) in the age groups of 1.5-<3.0 years and 0 (0/114) to 2.7% (3/111) in the age groups of 3.0-<7.0 years. The occurrence of assimilation was very low in all age groups, ranging from 0 (0/114) to 3.0% (3/100) among all age groups. For substitution, the occurrence order of mainly individual processes from high to low was listed as follows: retroflexion 35.4% (339/958), deretroflexion 31.6% (303/958), lateralization 27.9% (267/958), stopping 17.8% (171/958), backing 14.2% (136/958), palatalization 10.9% (104/958), fronting 10.6% (102/958), and nasalization 5.8% (56/958). From the 4.0-<4.5 years of age group onwards, the phonological processes in initial consonants all met suppression criteria (the occurrence of processes was reduced to<10%) except retroflexion, deretroflexion, and lateralization. Conclusions: The processes of syllable structure simplification and distortion mainly appears in the early stage of speech sound development, while substitution is the major form of phonological pattern in initial consonants found in developmental speech errors. By 4 years of age, phonological processes in initial consonants almost disappear. The remaining processes that persisted for a longer period of time are retroflexion, deretroflexion, and lateralization.

Abstract
BACKGROUND The aim of this study was to investigate the clinical characteristics of patients between active and inactive Takayasu's arteritis with pulmonary artery involvement (PTA) and to identify better markers of disease activity in these patients. METHODS Sixty-four PTA patients in Beijing Chao-yang hospital (2011 to 2021) were included. According to National Institutes of Health criteria, 29 patients were in active stage and 35 were in inactive stage. Their medical records were collected and analyzed. RESULTS Compared with inactive group, patients in active group were younger. More patients in active stage presented fever (41.38% vs 5.71%), chest pain (55.17% vs 20%), increased C-reactive protein (2.91 vs 0.46 mg/L), erythrocyte sedimentation rate (35.0 vs 9 mm/h), and platelet count (291 vs 221 × 109/L). Pulmonary artery wall thickening was more common in active group (51.72% vs 11.43%). These parameters were restored after treatment. The incidence of pulmonary hypertension was comparable between groups (34.48% vs 51.43%), but patients in active group had lower pulmonary vascular resistance (PVR) (361.0 vs 891.0 dyn·s·cm-5) and higher cardiac index (2.76 ± 0.72 vs 2.01 ± 0.58 L/min/m2). On multivariate logistic regression analysis, chest pain [odds ratio (OR) 9.37, 95%CI (1.98-44.38), P = 0.005], increased platelet count (>242.5 × 109/L) [OR 9.03, 95%CI (2.10-38.87), P = 0.003] and pulmonary artery wall thickening [OR 7.08, 95%CI (1.44-34.89), P = 0.016] were independently associated with disease activity. CONCLUSION Chest pain, increased platelet count, and pulmonary artery wall thickening are potential new indicators of disease activity in PTA. Patients in active stage may have lower PVR and better right heart function.

Abstract
BACKGROUND Rehabilitation nursing is considered an indispensable part of the cerebral infarction treatment system. The hospital–community–family trinity rehabilitation nursing model can provide continuous nursing services across hospitals, communities, and families for patients.
AIM To explore the application of a hospital–community–family rehabilitation nursing model combined with motor imagery therapy in patients with cerebral infarction.
METHODS From January 2021 to December 2021, 88 patients with cerebral infarction were divided into a study (n = 44) and a control (n = 44) group using a simple random number table. The control group received routine nursing and motor imagery therapy. The study group was given hospital–community–family trinity rehabilitation nursing based on the control group. Motor function (FMA), balance ability (BBS), activities of daily living (BI), quality of life (SS-QOL), activation status of the contralateral primary sensorimotor cortical area to the affected side, and nursing satisfaction were evaluated before and after intervention in both groups.
RESULTS Before intervention, FMA and BBS were similar (P > 0.05). After 6 months’ intervention, FMA and BBS were significantly higher in the study than in the control group (both P < 0.05). Before intervention, BI and SS-QOL scores were not different between the study and control group (P > 0.05). However, after 6 months’ intervention, BI and SS-QOL were higher in the study than in the control group (P < 0.05). Before intervention, activation frequency and volume were similar between the study and the control group (P > 0.05). After 6 months’ intervention, the activation frequency and volume were higher in the study than in the control group (P < 0.05). The reliability, empathy, reactivity, assurance, and tangibles scores for quality of nursing service were higher in the study than in the control group (P < 0.05).
CONCLUSION Combining a hospital–community–family trinity rehabilitation nursing model and motor imagery therapy enhances the motor function and balance ability of patients with cerebral infarction, improving their quality of life.

Abstract
Objective: To evaluate the safety and clinical efficacy of percutaneous mechanical thrombectomy (PMT) through ipsilateral calf venous access in the treatment of entire-limb acute deep vein thrombosis (DVT). Methods: From July 2017 to August 2020, the clinical data of patients with entire-limb acute DVT at Renji Hospital, School of Medicine, Shanghai Jiaotong University treated by AngioJet through ipsilateral calf venous access were analyzed retrospectively. All patients received rivaroxaban or warfarin anticoagulant therapy for at least 6 months after operation. Pressure gradient socks were given routinely after operation. All patients were followed up at 3, 6, 12 months and every year after operation. The primary end points were the 12-month primary patency rate and the incidence of post thrombotic syndrome (PTS). The secondary end points included the thrombus clearance rate, total complication rate, bleeding complication rate and the 12-month incidence of moderate to severe PTS. Results: A total of 31 patients were included in the study. The age ranged from 31 to 80 (63±14) years, including 16 males and 15 females, 23 left lower limb DVT and 8 right lower limb DVT. There were 15 cases treated through peroneal venous access, 6 cases through anterior tibial venous access and 10 cases through posterior tibial venous access. Moreover, 9 cases underwent combined catheter-directed thrombolysis, 25 cases underwent iliac vein percutaneous transluminal angioplasty (PTA), and 10 cases underwent iliac vein stenting. The thrombus clearance rate was grade Ⅱ in 19 cases (61.3%) and grade Ⅲ in 12 cases (38.7%). One patient (3.2%) with anterior tibial venous access developed hematoma at the puncture site, which was improved after pressure bandage, and there were no other bleeding and serious complications. All the 31 patients were followed up for at least 12 months, with an average follow-up period of (22±9) months. The 12-month primary patency rate was 77.4% (24/31). The 12-month incidence of PTS was 16.1% (5/31) and the incidence of moderate to severe PTS was 3.2% (1/31). Conclusions: PMT through ipsilateral calf venous access is safe and effective in the treatment of entire-limb acute DVT. Thrombus in the distal popliteal vein can be one-stage removed and the incidence of PTS is low. It is considered as the first choice of access for the endovascular treatment of entire-limb acute DVT.

Abstract
Background Atrial fibrillation (AF) is the most common form of clinical cardiac dysrhythmia responsible for thromboembolic cerebral stroke, congestive heart failure, and death. Aggregating evidence highlights the strong genetic basis of AF. Nevertheless, AF is of pronounced genetic heterogeneity, and in an overwhelming majority of patients, the genetic determinants underpinning AF remain elusive. Methods and Results By genome‐wide screening with polymorphic microsatellite markers and linkage analysis in a 4‐generation Chinese family affected with autosomal‐dominant AF, a novel locus for AF was mapped to chromosome 1q24.2–q25.1, a 3.20‐cM (≈4.19 Mbp) interval between markers D1S2851 and D1S218, with the greatest 2‐point logarithm of odds score of 4.8165 for the marker D1S452 at recombination fraction=0.00. Whole‐exome sequencing and bioinformatics analyses showed that within the mapping region, only the mutation in the paired related homeobox 1 (PRRX1) gene, NM_022716.4:c.319C>T;(p.Gln107*), cosegregated with AF in the family. In addition, sequencing analyses of PRRX1 in another cohort of 225 unrelated patients with AF revealed a new mutation, NM_022716.4:c.437G>T; (p.Arg146Ile), in a patient. The 2 mutations were absent in 908 control subjects. Biological analyses in HeLa cells demonstrated that the 2 mutants had significantly diminished transactivation on the target genes ISL1 and SHOX2 and markedly decreased ability to bind the promoters of ISL1 and SHOX2 (2 genes causally linked to AF), although with normal intracellular distribution. Conclusions This study first indicates that PRRX1 loss‐of‐function mutations predispose to AF, which provides novel insight into the molecular pathogenesis underpinning AF, implying potential implications for precisive prophylaxis and management of AF.

Abstract
PURPOSE The aim of this study was to explore the association of cardiac fibroblast activation with clinical parameters and cardiovascular magnetic resonance (CMR) imaging parameters in patients with chronic thromboembolic pulmonary hypertension (CTEPH). METHODS Thirteen CTEPH patients were prospectively enrolled. All of the patients underwent cardiac 68Gallium-labelled fibroblast activation protein inhibitor (68 Ga-FAPI-04)-positron emission tomography/computed tomography (PET/CT), right heart catheterisation, and echocardiography, and 11 of them additionally underwent CMR. Thirteen control subjects were selected to establish the normal range of cardiac 68 Ga-FAPI-04 uptake. Cardiac 68 Ga-FAPI-04 uptake higher than that in the blood pool was defined as abnormal. The global and segmental maximum standardised uptake values (SUVmax) of the right ventricle (RV) were measured and further expressed as target-to-background ratio (TBRRV) with left ventricular lateral wall activity as background. Late gadolinium enhancement (LGE) was visually evaluated, and native-T1 times, enhanced-T1 times, and extracellular volume (ECV) were quantitatively measured. RESULTS Ten CTEPH patients (77%) had abnormal 68 Ga-FAPI-04 uptake in RV, mainly located in the free wall, which was significantly higher than that in controls (TBRRV: 2.4 ± 0.9 vs 1.0 ± 0.1, P < 0.001). The TBRRV correlated positively with the thickness of RV wall (r = 0.815, P = 0.001) and inversely with RV fraction area change (RVFAC) (r = - 0.804, P = 0.001) and tricuspid annular plane systolic excursion (TAPSE) (r = - 0.678, P = 0.011). No correlation was found between 68 Ga-FAPI-04 activity and CMR imaging parameters. CONCLUSION Fibroblast activation in CTEPH, measured by 68 Ga-FAPI-04 imaging, is mainly localised in the RV free wall. Enhanced fibroblast activation reflects the thickening of the RV wall and decreased RV contractile function.

Abstract
OBJECTIVES A retrospective cohort study was designed to describe the clinical features and outcomes of pulmonary artery sarcoma (PAS). METHODS Twenty-two (22) consecutive patients diagnosed with PAS by pathological examination were enrolled and followed up until they died or until January 2020. The medical records were retrospectively reviewed to evaluate the clinical characteristics, image findings, and outcomes. RESULTS 1) Twenty-one (21, 95.5%) patients were firstly misdiagnosed. Dyspnoea was the most common presenting symptom (19 of 22, 86.4%). 2) Filling defects in the right pulmonary artery were seen in 17 patients (77.3%) with computed tomography pulmonary angiography or magnetic resonance pulmonary angiography. Among those patients, 14 underwent positron emission tomography-computed tomography detection and 13 (92.9%) were found to have increased uptake value in the pulmonary artery. 3) The median survival (from diagnosis to death or January 2020) of the total series was 11.6 months (range, 0.7-68.5 months). The estimated cumulative survival rates at 1, 2, and 3 years were 52.6%, 32.8%, and 19.7%, respectively. Patients who received surgery and/or chemo-radiotherapy treatment had a better survival rate compared with patients without treatment (the estimated cumulative survival rates at 1, 2, and 3 years were 60.3%, 39.1%, and 29.3%, respectively, vs 33.3%, 16.6%, and 0, accordingly) and better survival time (median survival 17.02 vs 3.16 months, respectively) (p=0.025). CONCLUSIONS Pulmonary artery sarcoma is easily misdiagnosed, as the symptoms and routine image detection are nonspecific. Positron emission tomography-computed tomography may be helpful in diagnosis. Surgery and/or chemo-radiotherapy offer a chance for better outcomes.

Abstract
AIMS To explore the value of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in the detection of active pulmonary artery (PA) lesions in patients with Takayasu's arteritis (TA). METHODS AND RESULTS Consecutive TA patients with PA involvement were prospectively recruited. Clinical activity was assessed according to the National Institutes of Health (NIH) criteria. CT pulmonary angiography (CTPA) or magnetic resonance pulmonary angiography was performed for evaluation of vascular structural characteristics, and mural thickening was considered as radiologically active. A vascular segment with 18F-FDG uptake ≥ liver was considered as PET-active. A total of 38 18F-FDG PET/CT scans were performed in 29 patients. In terms of disease activity, the sensitivity of 18F-FDG PET/CT did not significantly differ from radiological imaging (71.4% vs. 92.9%, P = 0.250), but 18F-FDG PET/CT had higher specificity (91.7% vs. 37.5%, P = 0.001) and accuracy (84.2% vs. 57.9%, P = 0.022). Although the majority of PET-active PA segments (54.9%) showed mural thickening, 14 PA segments with normal structure were also PET-active. 18F-FDG activity did not significantly differ between the PA and aorta in clinically active patients. In addition, 18F-FDG activity of the PA was positively correlated with inflammatory markers. Changes in 18F-FDG activity in PA during follow-up reflected therapeutic effects. CONCLUSION 18F-FDG PET/CT can effectively evaluate PA activity in TA patients, and its diagnostic performance is superior to radiological imaging. The 18F-FDG activity of PA shows a good correlation with clinical disease status and inflammatory markers and can be used to monitor therapeutic effects.

Abstract
Sclerotinia stem rot (SSR) of rapeseed (Brassica napus), caused by the soil-borne fungus Sclerotinia sclerotiorum, is one of the main diseases seriously affecting the yield and oil quality of infected rapeseed crops. The complexity of the inheritance of resistance and of the interaction mechanisms between rapeseed and S. sclerotiorum limits resistance gene identification and molecular breeding. In this review, the latest progress of research into resistance to SSR in B. napus is summarized from the following three directions: the pathogenesis mechanisms of S. sclerotiorum, the resistance mechanisms of B. napus toward S. sclerotiorum, and rapeseed breeding for resistance to SSR. This review aims to provide a theoretical basis and useful reference for analyzing the mechanism of the interaction between B. napus and S. sclerotiorum, searching for gene loci associated with the resistance response, and for achieving disease-resistance genetic manipulation and molecular design breeding in rapeseed.

Abstract
Reduced inflammation is one of the potential mechanisms underlying the cardioprotective efficacy of fish oil enriched with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Supplementation with fish oil has favorable effects on cardiometabolic profiles in Inner Mongolia patients with hypertension, but whether the cardiovascular benefits can be ascribed to reduced subclinical inflammation is unclear among this population. Seventy-seven middle-aged/elderly hypertensive volunteers were randomly assigned to receive either fish oil (FO, n = 38, 2 g day-1 EPA + DHA) or control corn oil (CO, n = 39) for 90 days. FA compositions in erythrocytes and C-reactive protein (CRP, mg L-1), interleukin-6 (IL-6, pg mL-1) and tumor necrosis factor-α (TNF-α, pg mL-1) concentrations in the plasma were measured before and after the 90-day supplementation, and the cardiometabolic risk was expressed as continuously distributed z-scores calculated by standardizing and then summing the individual cardiovascular risk factors. Significant reductions in the TNF-α (-1.87 ± 2.71 vs. -0.64 ± 2.62, p = 0.02) and CRP levels (-0.85 ± 2.49 vs. 0.56 ± 2.14, p = 0.01) were found in the FO group compared with the CO group, but not in the IL-6 levels (-0.66 ± 1.05 vs. -0.25 ± 0.94, p = 0.10). The decreases in the changes of TNF-α levels were positively correlated with the reductions in the cardiometabolic risk scores in the subjects supplemented with FO (r = 0.35, p = 0.02), but not in the control subjects supplemented with CO (r = 0.09, p = 0.54). FO supplementation increased the levels of EPA (p = 0.013), DHA (p = 0.040) and total n-3 FA (p = 0.035), and decreased the levels of 20:4n-6 (p = 0.041) and total n-6 FA (p = 0.011) and the ratio of n-6 to n-3 FA (p = 0.001), compared with the changes related to the CO group. The increases in the changes of erythrocyte total n-3 FA levels were inversely correlated with the concentrations of TNF-α (r = -0.34, p = 0.001) and CRP (r = -0.29, p = 0.020). The present findings suggest that fish oil supplementation may attenuate the proinflammatory reactions in hypertension, which might help promote the cardiometabolic benefits in this Inner Mongolia population.

Abstract
Atrial fibrillation (AF) represents the most frequent form of sustained cardiac rhythm disturbance, affecting approximately 1% of the general population worldwide, and confers a substantially enhanced risk of cerebral stroke, heart failure, and death. Increasing epidemiological studies have clearly demonstrated a strong genetic basis for AF, and variants in a wide range of genes, including those coding for ion channels, gap junction channels, cardiac structural proteins and transcription factors, have been identified to underlie AF. Nevertheless, the genetic pathogenesis of AF is complex and still far from completely understood. Here, whole-exome sequencing and bioinformatics analyses of a three-generation family with AF were performed, and after filtering variants by multiple metrics, we identified a heterozygous variant in the ISL1 gene (encoding a transcription factor critical for embryonic cardiogenesis and postnatal cardiac remodeling), NM_002202.2: c.481G > T; p.(Glu161*), which was validated by Sanger sequencing and segregated with autosome-dominant AF in the family with complete penetrance. The nonsense variant was absent from 284 unrelated healthy individuals used as controls. Functional assays with a dual-luciferase reporter assay system revealed that the truncating ISL1 protein lost transcriptional activation on the verified target genes MEF2C and NKX2-5. Additionally, the variant nullified the synergistic transactivation between ISL1 and TBX5 as well as GATA4, two other transcription factors that have been implicated in AF. The findings suggest ISL1 as a novel gene contributing to AF, which adds new insight to the genetic mechanisms underpinning AF, implying potential implications for genetic testing and risk stratification of the AF family members.

Abstract
Objective To establish a method for determination of escitalopram in biological samples by ultrasound-assisted ionic liquid-dispersive liquid-liquid microextraction combined with gas chromatography-tandem mass spectrometry (GC-MS/MS) and provide evidences for forensic determination of cases related to escitalopram. Methods The 1-hexyl-3-methylimidazolium hexafluorophosphate ([C6MIM][PF6]) was selected as an extract solvent to process biological samples. Ultrasound-assisted extraction was used on the samples. Then the samples were detected by GC-MS/MS. Results The linear range of escitalopram in blood and liver were 5.56-1 111.10 ng/mL and 0.025-5.00 mg/g, respectively. The correlation coefficient (r) were greater than 0.999, limit of detection (LOD) were 4.00 ng/mL and 2.00 μg/g, limit of quantitation (LOQ) were 14.00 ng/mL and 6.00 μg/g, respectively. The extraction recovery rates were all greater than 50%, the interday and intraday precision were less than 20%. Escitalopram was detected in blood and liver samples from the actual poisoning case by this method with a content of 1.26 μg/mL and 0.44 mg/g, respectively. Conclusion The ultrasound-assisted ionic liquid-dispersive liquid-liquid microextraction combined with GC-MS/MS is environment friendly, rapid, has good enriching effect and consumes less organic solvent and can be used for forensic determination of escitalopram related cases.

Abstract
Heat shock protein 90 (Hsp90) plays a very important role in facilitating the replication of many viruses. Until now, little has been known about the role of Hsp90 in Bombyx mori virus infection. In this study, we explored the role of BmHsp90 in B. mori nucleopolyhedrovirus (BmNPV) replication. We found that BmHsp90 inhibition by geldanamycin (GA) significantly reduced the BmNPV titre, the protein expression level of BmNPV nucleocapsid protein 39 (VP39) and the transcript level of BmNPV genes. Silencing the hsp90 gene in BmN cells by small interfering RNA suppressed BmNPV replication whereas overexpression of hsp90 promoted the replication of BmNPV. After inhibition of Hsp90, the expression of three key genes [signal transducing activator of transcription (stat), suppressor of cytokine signalling protein 2 (socs2), socs6] involved in the Janus kinase/STAT pathway significantly changed, with up-regulation of stat and down-regulation of socs2 and socs6. In addition, the expression of two antiapoptosis genes, BmNPV inhibitor of apoptosis protein1 (BmNPV-iap1) and Bmiap2, was greatly decreased in GA-treated cells, whereas their expression was significantly increased in hsp90-overexpressed silkworm larvae. Our results indicated that inhibition of Hsp90 can suppress BmNPV proliferation in B. mori. Our findings may provide new clues to elucidate the molecular mechanisms of silkworm-virus interactions.

Abstract
Objective: To study the prevalence of c-ros oncogene 1 fusion in lung adenocarcinoma and to evaluate its relationship with clinical characteristics. Methods: We retrospectively analyzed epidermal growth factor receptor (EGFR) mutation, anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 (ROS1) fusion in 1 482 patients with adenocarcinoma from March 2014 to January 2017 in the first affiliated hospital of Zhejiang University. Furthermore, ROS1 fusion positive patients diagnosed between February 2017 and December 2017 were also included in ROS1 positive group. The data of age, sex, smoking history, TNM stage and chest computed tomography were collected by Electronic Medical Record (EMR). The clinical data were compared by the chi-squared test or Mann-Whitney test. Results: Of these 1 482 patients,54 cases were diagnosed with ROS1 rearrangement, including 19 males and 35 females, while 73 cases were diagnosed with ALK rearrangement, including 28 males and 45 females, and 679 cases diagnosed with EGFR mutation including 293 males and 386 females. And there were 676 patients without driven genes mutation. The mean age in ROS1 fusion group (54±12) was lower than EGFR mutation group (60±11, z=-3.982, P<0.001) and WT group (62±10, z=-4.944, P<0.001). Female proportion in ROS1 fusion group (64.8%, 35/54) was higher than WT group (28.4%, 192/676, χ(2)=30.94, P<0.001). Non-smoker percentages in ROS1 fusion group (72.2%, 39/54) was significantly higher than WT group (38.0%,257/676, χ(2)=24.27, P<0.001). ROS1 fusion group was similar to ALK fusion group in sex, age and smoking history, and there were no significant difference in TNM stage among these groups. On chest CT, adenocarcinomas with ROS1 fusion were found to be more peripheral in location (71.4%, 20/28) and solid in density (75%, 21/28), usually with lobulated margins (75.0%, 21/28) and spiculated in contour (57.1%,16/28). Conclusion: In our study lung adenocarcinoma with c-ROS oncogene 1 fusion was a rare subtype lung cancer and was usually detected in young, never smoking, and female patients.

Abstract
To determine the value of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in differentiating malignancy of pulmonary artery (PA) from pulmonary thromboembolism (PTE) based on a larger number of cases by pooling our cases and those from the literature. Consecutive patients with a PA lesion who had undergone 18F-FDG PET/CT in our hospital were retrospectively reviewed. Moreover, PubMed, Embase, and Medline were searched for literature reporting individual maximum standardised uptake value (SUVmax) of the malignant PA lesion and/or PTE. 18F-FDG activity was compared between PA malignancy and PTE by pooling the data from literature and our patients. Receiver operating characteristic curve analysis was performed to determine the ability of SUVmax to differentiate PA malignancy from PTE. From our database, we identified 11 patients with pulmonary artery sarcoma (PAS), and nine cases of PTE. Fifty patients with a malignant PA lesion (40 cases of PAS and 10 cases of tumor embolism) and 22 subjects with PTE were extracted from the literature. In our cases, the SUVmax of PAS (11.1 ± 4.9, range: 5.5-19.9) was significantly higher than that of PTE (1.9 ± 0.6, range: 1.1-3.2; P < 0.001). There was no significant difference in the SUVmax between the literature data and our cases in malignant lesions or in PTE. Based on the pooled analysis of the literature data and our cases (61 cases of malignant lesions and 31 cases of PTE), the area under the curve for SUVmax to differentiate PA malignancy from PTE was 0.996 (95% CI: 0.989-1.000). At a cutoff value of 3.3, the sensitivity, specificity, and accuracy were 98.4%, 96.8%, and 97.8%, respectively. The 18F-FDG uptake value is an accurate index for determining PA malignancy.

Abstract
Seed germination rate and oil content can be regulated at theGDSL transcriptional level by eitherAtGDSL1 orBnGDSL1 inB. napus. Gly-Asp-Ser-Leu (GDSL)-motif lipases represent an important subfamily of lipolytic enzymes, which play important roles in lipid metabolism, seed development, abiotic stress, and pathogen defense. In the present study, two closely related GDSL-motif lipases, Brassica napus GDSL1 and Arabidopsis thaliana GDSL1, were characterized as functioning in regulating germination rate and seed oil content in B. napus. AtGDSL1 and BnGDSL1 overexpression lines showed an increased seed germination rate and improved seedling establishment compared with wild type. Meanwhile, the constitutive overexpression of AtGDSL1 and BnGDSL1 promoted lipid catabolism and decreased the seed oil content. While RNAi-mediated suppression of BnGDSL1 (Bngdsl1) in B. napus improved the seed oil content and decreased seed germination rate. Moreover, the Bngdsl1 transgenic seeds showed changes in the fatty acid (FA) composition, featuring an increase in C18:1 and a decrease in C18:2 and C18:3. The transcriptional levels of six related core enzymes involved in FA mobilization were all elevated in the AtGDSL1 and BnGDSL1 overexpression lines, but strongly suppressed in the Bngdsl1 transgenic line. These results suggest that improving the seed germination and seed oil content in B. napus could be achieved by regulating the GDSL transcriptional level.

Abstract
Whether n-3 fatty acid (FA) has hypotensive actions among Chinese adults remains inconclusive. Hypertensive patients from Inner Mongolia, China ( n = 126) were recruited to a double-blind, randomized controlled trial. We investigated the effects of n-3 FA supplements on blood pressure (BP, mm Hg), plasma concentrations of angiotensin II (Ang II, pg/mL), and nitric oxygen (NO, μmol/L), using fish oil ( n = 41, 4 capsules/day, equivalent to 2 g of eicosapentaenoic acid plus docosahexaenoic acid) and flaxseed oil ( n = 42, 4 capsules/day, equivalent to 2.5 g of α-linolenic acid). Comparing to the control group (corn oil, n = 43), the mean systolic BP (-4.52 ± 9.28 vs -1.51 ± 9.23, P = 0.040) and the plasma Ang II levels (-12.68 ± 10.87 vs -4.93 ± 9.08, P = 0.023) were significantly lowered in the fish oil group, whereas diastolic BP ( P = 0.285) and plasma NO levels ( P = 0.220) were not. Such findings suggest that marine-based n-3 FA has a hypotensive efficacy in Chinese hypertensive patients possibly through inhibiting Ang II-dependent vasoconstrictions.

Abstract
BACKGROUND To study the effective therapeutic concentration, drug application duration, irradiation duration and irradiation dosage of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) for treating vitiligo and observe its clinical efficacy. OBJECTIVE To assess the clinical efficacy of ALA-PDT for treating vitiligo. METHODS ALA with different drug concentrations, drug application durations, irradiation durations and irradiation dosages were adopted to treat skin lesions caused by vitiligo to determine the effective drug concentration, drug application duration, irradiation duration and irradiation dosage for treating three vitiligo volunteers and observe the therapeutic results. RESULTS The clinical trial suggested that ALA at a drug concentration of 1.5%, drug application duration for 3 hours, irradiation dosage of 80mw/cm2 and irradiation duration for 20 min was effective in treating vitiligo. Under these parameters, ALA-PDT was effective to the three vitiligo volunteers, with mild pain and feeling of burning but no other adverse reaction during treatment. STUDY LIMITATIONS Due to the small sample size in this study for the effectiveness of PDT in treating vitiligo and the potential variations in the efficacy for treating the disease at different areas, further studies shall be conducted for confirmation. CONCLUSIONS ALA with a drug concentration at 1.5%, drug application duration for 3 hours, irradiation dosage of 80 mw/cm2 and irradiation duration for 20 min is effective in treating vitiligo. Therefore, ALA-PDT is safe and effective in treating the disease, with minor adverse events, providing a new method for treating vitiligo in the future.

Abstract
Plasmid bearing adenovirus genome is generally constructed with the method of homologous recombination in E. coli BJ5183 strain. Here, we utilized Gibson gene assembly technique to generate infectious clone of fowl adenovirus 4 (FAdV-4). Primers flanked with partial inverted terminal repeat (ITR) sequence of FAdV-4 were synthesized to amplify a plasmid backbone containing kanamycin-resistant gene and pBR322 origin (KAN-ORI). DNA assembly was carried out by combining the KAN-ORI fragment, virus genomic DNA and DNA assembly master mix. E. coli competent cells were transformed with the assembled product, and plasmids (pKFAV4) were extracted and confirmed to contain viral genome by restriction analysis and sequencing. Virus was successfully rescued from linear pKFAV4-transfected chicken LMH cells. This approach was further verified in cloning of human adenovirus 5 genome. Our results indicated that DNA assembly technique simplified the construction of infectious clone of adenovirus, suggesting its possible application in virus traditional or reverse genetics.

Abstract
Take-all is a severe root disease of wheat worldwide that is caused by the soilborne fungal pathogen Gaeumannomyces graminis var. tritici (Ggt). In this study, 272 Bacillus isolates were screened for their antifungal activity in vitro to Ggt. Of the 128 strains that demonstrated an antagonistic action, 24 of these exhibited at least three of the four plant growth promotion parameters (i.e. indole acetic acid and siderophore production, inorganic phosphorus solubilization and organic phosphorus solubilization) that were tested in wheat plants. The most effective strain found was Bacillus subtilis Pnf-12; its disease reduction effect reached 69%. Pnf-12 also caused a significant improvement (P < 0·05) in the root and shoot weights of wheat plants, though their root length and shoot height were similar to the noninoculated treatment (P > 0·05). The mechanism for this disease control may be linked to the production of the antifungal lipopeptides surfactin, iturin and fengycin production, all of which were detected in the cell-free supernatant of Pnf-12. SIGNIFICANCE AND IMPACT OF THE STUDY Take-all, which is caused by the soilborne fungal pathogen Gaeumannomyces graminis var. tritici (Ggt), is one of the most widespread and devastating root diseases of wheat plants. This study focuses on a novel screening strategy of Bacillus isolates to evaluate their potential biological control capacity for suppressing wheat take-all. The joint assessment of antifungal activities, growth promotion factors and variety of antibiotic synthesis genes, in addition to greenhouse experiments, allowed for the identification and demonstration of the Bacillus isolate Pnf-12 as an effective disease control agent.

Abstract
Atrial fibrillation (AF), as the most common sustained cardiac arrhythmia, is associated with substantially increased morbidity and mortality. Aggregating evidence demonstrates that genetic defects play a crucial role in the pathogenesis of AF, especially in familial AF. Nevertheless, AF is of pronounced genetic heterogeneity, and in an overwhelming majority of cases the genetic determinants underlying AF remain elusive. In the current study, 162 unrelated patients with familial AF and 238 unrelated healthy individuals served as controls were recruited. The coding exons and splicing junction sites of the SHOX2 gene, which encodes a homeobox-containing transcription factor essential for proper development and function of the cardiac conduction system, were sequenced in all study participants. The functional effect of the mutant SHOX2 protein was characterized with a dual-luciferase reporter assay system. As a result, a novel heterozygous SHOX2 mutation, c.580C>T or p.R194X, was identified in an index patient, which was absent from the 476 control chromosomes. Genetic analysis of the proband's pedigree revealed that the nonsense mutation co-segregated with AF in the family with complete penetrance. Functional assays demonstrated that the mutant SHOX2 protein had no transcriptional activity compared with its wild-type counterpart. In conclusion, this is the first report on the association of SHOX2 loss-of-function mutation with enhanced susceptibility to familial AF, which provides novel insight into the molecular mechanism underpinning AF, suggesting potential implications for genetic counseling and individualized management of AF patients.

Abstract
OBJECTIVES To study the expression change of pro-brain natriuretic peptide (proBNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in sudden death of coronary atherosclerotic heart disease, and to explore its application in forensic diagnosis. METHODS Myocardial and blood samples were collected from normal control group, sudden death of coronary atherosclerotic heart disease group and single coronary stenosis group (20 cases in each group). The expression of proBNP in myocardial samples were detected by immunohistochemical staining and Western blotting, and that of BNP mRNA were detected by reverse transcription PCR (RT-PCR). The content of NT-proBNP in plasma were detected by ELISA. RESULTS Immunohistochemical staining showed positive expression of proBNP in both sudden death of coronary atherosclerotic heart disease group and single coronary stenosis group. There was no positive expression in normal control group. For sudden death of coronary atherosclerotic heart disease group and single coronary stenosis group, the relative expression of proBNP protein and BNP mRNA in myocardial tissue and the NT-proBNP content in plasma were higher than that of normal control group (P<0.05). The NT-proBNP content in plasma of sudden death of coronary atherosclerotic heart disease group was higher than that of single coronary stenosis group (P<0.05). CONCLUSIONS In myocardial ischemia condition, the higher expression of proBNP in cardiac muscle cell shows that the detection of NT-proBNP in plasma can be useful to differentially diagnose the degree of coronary atherosclerotic heart disease and determine whether the sudden death due to coronary atherosclerotic heart disease.

Abstract
Serum neutralizing antibodies to Ad5 and Ad41 in adults and children were titrated. Prevalence of NAb in children was associated with age and sanitary conditions. NAb titer distribution pattern was very different between Ad5 an Ad41. Ad41 vectored vaccine candidates might have a bright future.
Neutralizing antibody (NAb) can dampen the immunogenicity of adenovirus (Ad) vector-based vaccine. Vector systems based on human adenovirus type 41 (Ad41) have been constructed and used to develop recombinant vaccines. Here, we attempted to study the seroprevalence of NAbs to Ad5 and Ad41 among children and adults in Qinghai province, China. The positive rates (titer ⩾ 40) of Ad5 and Ad41 NAb in adults from Xining city were 75.7% and 94.7%, respectively. The moderate/high-positive rates (titer ⩾ 160) of NAb were quite close between the two viruses in adults (70.4% for Ad5 and 73.5% for Ad41). Age-dependent increase of NAb seroprevalence was observed for both viruses in children. NAb-positive rate of Ad41 reached 50% at 3.3–4.6 years of age for children from Chengxi district, Xining city, approximately 1.5 years earlier than that of Ad5 did. Interestingly, NAb level was also associated with sanitary conditions among young children. For Ad5, 8–15% children (0.2–3.0 years of age) from city or town, where the sanitations were relatively better, had moderate/high-positive NAb, while the same rate was 62% for children from villages. For Ad41, 22% children from city, 47% from town and 88% from villages possessed moderate/high-positive NAb. The possible influence of NAb titer distributions on the application of Ad41-vectored vaccines was discussed in detail. Our results suggested that children from places with poor sanitations should be included for comprehensive Ad NAb seroprevalence studies, and provided insights to the applications of Ad41 vectors.

Abstract
Background Circulating long-chain (LC) n-3 polyunsaturated fatty acid (PUFA) can provide objective measures that reflect both dietary consumption and relevant biological processes. Nevertheless, prospective cohort studies on circulating LC n-3 PUFA in relation to incidence of stroke have yielded inconsistent results. We therefore conducted a meta-analysis to quantitatively evaluate the association. Results A total of 2,836 stroke events occurred among 20,460 individuals aged 35–79 yr from 10 prospective cohort studies. Circulating LC n-3 PUFA was significantly associated with reduced risk of stroke (RR: 0.86; 95% CI: 0.76, 0.98; I2 = 0.00%), especially 22:5n-3 (RR: 0.74; 95% CI: 0.60, 0.92) and 22:6n-3 (RR: 0.78; 95% CI: 0.65, 0.94). The associations were more pronounced with ischemic stroke (RR: 0.81; 95% CI: 0.68, 0.96), but not with hemorrhagic stroke (RR: 0.95; 95% CI: 0.60, 1.49). A 1% increment of 22:5n-3 and 22:6n-3 proportions in circulating blood was associated with 25% (RR: 0.75; 95% CI: 0.64, 0.87) and 11% (RR: 0.89; 95% CI: 0.83, 0.95) reduced risk of stroke, respectively. Materials and Methods Pertinent studies were identified from Cochrane Library, PubMed and EMBASE database through June 2017. Multivariate-adjusted risk ratios (RRs) with 95% confidence interval (CI) for incident stroke when comparing the top with the bottom tertiles of baseline LC n-3 PUFA proportions in blood were pooled using a random-effect model. Conclusions Circulating LC n-3 PUFAs were linearly associated with reduced risk of stroke, especially 22:5n-3 and 22:6n-3. Such findings highlight the importance of circulating LC n-3 PUFA in the development of ischemic stroke.

Abstract
BACKGROUND Clinical and imaging manifestations are similar in pulmonary artery sarcomas (PAS) and thromboembolic diseases, especially central chronic pulmonary thromboembolism (CPTE). The feasibility of utilising clinical imaging tools such as computed tomography (CT) and magnetic resonance imaging (MRI) for differential diagnosis of PAS and CPTE has not been fully explored, especially MRI. METHODS Patients with PAS (n=18) and central CPTE (n=20) treated at our hospital between January 2013 and September 2016 were identified retrospectively. Computed tomography and MRI findings of pulmonary artery (PA) filling defects including the location, the involvement of pulmonary artery, morphology, signal intensities and enhancement in MRI, calcification, sizes of right atrium and ventricle, inner diameters of the pulmonary artery trunk and branches, and mediastinal collateral circulation in both groups were examined, and differences were analysed by Fisher exact test and independent sample t-test. RESULTS Compared to those of central CPTE, PAS lesions were in full shape or expansive growth (p<0.001), and the proximal end of the tumours was often bulging or lobulated (p<0.001). These lesions were aneurysm- or grape-like distally (p<0.01) with inhomogeneous enhancement (p<0.001). The MRI contrast enhancement pattern of PAS lesions were cloudy with inhomogeneous delayed enhancement and the time-density curves for some of the lesions increased gradually. CONCLUSION Computed tomographic and MR imaging manifestations may resemble PAS and central CPTE; however, some manifestations still have great value for the differential diagnosis of these two conditions, specifically the morphology and MRI enhancement patterns.

Abstract
BACKGROUND We aimed to explore the relation between the microstructural integrity of white matter using the technique of diffusion tensor imaging (DTI) and changes of cognition in leukoaraiosis (LA). METHODS Fifty patients with LA and 50 age- and gender-matched controls were recruited consecutively. The average values of mean diffusivity (MD) and fractional anisotropy (FA) were quantified both within white matter lesions (WMLs) and normal-appearing white matter (NAWM) from the regions of interest (ROIs). RESULTS We found significantly decreased FA and increased MD in WMLs at the 5 ROIs than that in NAWM and controls (p < 0.05). The values of FA in NAWM were significantly lower at centrum semiovale and posterior periventricular white matter than those of controls (p < 0.05). The values of MD in NAWM were significantly higher at the anterior periventricular white matter and corpus callosum than those of controls (p < 0.05). The values of FA in NAWM located at anterior periventricular white matter correlated inversely with the Z scores of executive function (r = -0.420, p = 0.028). CONCLUSIONS DTI may provide some important information about the cognitive dysfunction in patients with LA, which may largely attribute to the "disconnection" of cortico-subcortical pathways, with the evidence of reduced FA and increased MD.

Abstract
Uropathogenic Escherichia coli (UPEC), the primary uropathogen, adhere to and invade bladder epithelial cells (BECs) to establish a successful urinary tract infection (UTI). Emerging antibiotic resistance requires novel nonantibiotic strategies. Our previous study indicated that luteolin attenuated adhesive and invasive abilities as well as cytotoxicity of UPEC on T24 BECs through down-regulating UPEC virulence factors. The aims of this study were to investigate the possible function of the flavonoid luteolin and the mechanisms by which luteolin functions in UPEC-induced bladder infection. Firstly, obvious reduction of UPEC invasion but not adhesion were observed in luteolin-pretreated 5637 and T24 BECs sa well as mice bladder via colony counting. The luteolin-mediated suppression of UPEC invasion was linked to elevated levels of intracellular cAMP induced by inhibiting the activity of cAMP-phosphodiesterases (cAMP-PDEs), which resulting activation of protein kinase A, thereby negatively regulating Rac1-GTPase-mediated actin polymerization. Furthermore, p38 MAPK was primarily and ERK1/2 was partially involved in luteolin-mediated suppression of UPEC invasion and actin polymerization, as confirmed with chemical activators of p38 MAPK and ERK1/2. These data suggest that luteolin can protect bladder epithelial cells against UPEC invasion. Therefore, luteolin or luteolin-rich products as dietary supplement may be beneficial to control the UPEC-related bladder infections, and cAMP-PDEs may be a therapy target for UTIs treatment. © 2016 BioFactors, 42(6):674-685, 2016.

Abstract
OBJECTIVE To evaluate antibacterial and residual antimicrobial activities of five root canal irrigants including Qmix, MTAD(mixture of a tetracycline isomer, an acid, and a detergent), 0.2% cetrimide(CTR), 2% chlorhexidine(CHX) and 17% ethylene diaminetetraacetic acid(EDTA) and to find the most optimal final irrigants for using in root canal therapy. METHODS The standard enterococcus infection models were built up in 100 single rooted incisors with single canal. Totally 30 teeth were selected by using random number tablefor detecting the quality of the bacteria model. Crown-down technique with rotary ProTaper system was used to prepare the root canals. Then the teeth were randomly divided into seven groups of which five groups were irrigated with five different irrigants respectively, one group was irrigated with distilled water(distilled water group) and one group was no-irrigation group. Each tooth was sectioned into three parts: apical 1/3, middle 1/3 and coronal 1/3. After irrigation, specimenswere cultivated from day 0 to day 14. All statistical analyses were performed by means of SPSS 17.0 software. Chi-squared test was used to evaluate antibacterial activities. Generalized estimating equations was used to evaluate residual antimicrobial activities. RESULTS All samples rinsed with Qmix, MTAD, CTR, CHX were bacteria-free in 0 day. The samples rinsed with EDTA and distilled water had no bacteria in 7 coronal sections, 6 middle sections and 9 apical sections, respectively. The results of Qmix, MTAD, CTR and CHX groups showed significant difference when compared with that of distilled water, EDTA and control groups(P<0.05). Residual antimicrobial resultsin EDTA, distilled water, no-irrigation groups showed significant differences compared with that of Qmix, MTAD, CTR, CHX groups according to pairwise comparison(P<0.05) on day 1, 2 and 3. There was no significant difference between the other two groups(P>0.05). Antimicrobial properties on the coronal 1/3 and apical 1/3, middle 1/3 and apical 1/3 showed significant difference(P<0.05) while middle 1/3 and coronal 1/3 showed no significant difference(P>0.05). CONCLUSIONS Qmix, MTAD, CTR and CHX had an antimicrobial activity, but could not destroy Enterococcus faecalis completely. Antimicrobial activity in coronal 1/3 was better than in apical 1/3. Qmix, MTAD, CTR and CHX had a residual antimicrobial activity with various lasting times. The lasting time of residual antimicrobial activity was as follow: MTAD> CTR>Qmix>CHX. EDTA had no antibacterial and residual antimicrobial activities.

Abstract
OBJECTIVES To explore the value of mast cell tryptase and brain natriuretic peptide(BNP) in the differential diagnostic of sudden death due to hypersensitivity and coronary atherosclerotic heart disease. METHODS Totally 30 myocardial samples were collected from the autopsy cases in the Department of Forensic Pathology, Shanxi Medical University during 2010-2015. All samples were divided into three groups: death of craniocerebral injury group, sudden death of hypersensitivity group and sudden death of coronary atherosclerotic heart disease group, 10 cases in each group. Mast cell tryptase and BNP in myocardium were detected by immunofluorescence staining and Western Blotting. RESULTS Immunofluorescence staining showed that the positive staining mast cell tryptase appeared in myocardium of sudden death of hypersensitivity group and coronary atherosclerotic heart disease group. Among the three groups, the expression of mast cell tryptase showed significantly differences through pairwise comparison (P<0.05); The expression level of BNP in sudden death of coronary atherosclerotic heart disease group were significantly higher than the sudden death of hypersensitivity group and death of craniocerebral injury group (P<0.05). The difference of the expression level of BNP between the sudden death of hypersensitivity group and the death of craniocerebral injury group had no statistical significance (P>0.05). CONCLUSIONS The combined detection of the mast cell tryptase and BNP in myocardium is expected to provide help for the forensic differential diagnosis of sudden death due to hypersensitivity and coronary atherosclerotic heart disease.

Abstract
Petrochemical wastewater often contains high concentrations of phenol and sulfate that must be properly treated to meet discharge standards. This study acclimated anaerobic-activated sludge to treat saline phenolic wastewater with sulfate reduction and clarified the diversity and degradation mechanism of the microbial community. The active sludge in an upflow anaerobic sludge blanket (UASB) reactor could remove 90 % of phenol and maintain the effluent concentration of SO4 (2-) below 400 mg/L. Cloning and sequencing showed that Clostridium spp. and Desulfotomaculum spp. were major phenol-degrading bacteria. Phenol was probably degraded through the carboxylation pathway and sulfate reduction catalyzed by adenosine-5'-phosphosulfate (APS) reductase and dissimilatory sulfite reductase (DSR). A real-time polymerase chain reaction (RT-PCR) showed that as phenol concentration increased, the quantities of 16S rRNA gene, dsrB, and mcrA in the sludge all decreased. The relative abundance of dsrB dropped to 12.46 %, while that of mcrA increased to 56.18 %. The change in the electron flow ratio suggested that the chemical oxygen demand (COD) was removed mainly by sulfate-reducing bacteria under a phenol concentration of 420 mg/L, whereas it was removed mainly by methanogens above 630 mg/L.

Abstract
Background: No data on the incidence of pleural effusion (PE) in Chinese patients with pulmonary embolism are available to date. The aim of the current study was to investigate the frequency of PE in a Chinese population of patients with pulmonary embolism. Methods: This was a retrospective observational single-center study. All data of computed tomography pulmonary angiography (CTPA) performed over 6-year period on adult patients with clinically suspected pulmonary embolism were analyzed. Results: From January 2008 until December 2013, PE was identified in 423 of 3141 patients (13.5%) with clinically suspected pulmonary embolism who underwent CTPA. The incidence of PE in patients with pulmonary embolism (19.9%) was significantly higher than in those without embolism (9.4%) (P < 0.001). Majority of PEs in pulmonary embolism patients were small to moderate and were unilateral. The locations of emboli and the numbers of arteries involved, CT pulmonary obstruction index, and parenchymal abnormalities at CT were not associated with the development of PE. Conclusions: PEs are present in about one fifth of a Chinese population of patients with pulmonary embolism, which are usually small, unilateral, and unsuitable for diagnostic thoracentesis.

Abstract
Early rehabilitative therapy is important for patients with hypertensive cerebral hemorrhage to improve long-term function of the extremities. Vascular endothelial growth factor (VEGF) is closely associated with the pathogenesis of hypertension. To identify the markers contributing to the genetic susceptibility to hypertensive cerebellar hemorrhage (HCH) and rehabilitative treatment, we examined the potential association between HCH and 12 single nucleotide polymorphisms of the VEGF gene. Participants included 244 patients with HCH and 251 healthy controls from our rehabilitation department. The T allelic frequencies of the rs3025020 (intron 6) and rs3025039 (3'-UTR) polymorphisms were significantly higher in the patients with HCH than in the healthy controls (rs3025020 T allele: P = 0.0002, OR = 1.619, 95%CI = 1.256-2.088; rs3025039 T allele: P = 0.001, OR = 1.682, 95%CI = 1.246-2.270). Strong linkage disequilibrium was observed in three blocks (D' > 0.9), and significantly more C-G-C (rs3025020, rs3025030, and rs3025039) haplotypes (P = 0.001) were found in the controls in block 3. Significantly more T-G-C haplotypes were found in the patients with HCH (P = 0.046). Further genotype and clinical phenotype correlation study of the rs3025039 carriers showed that Fugl-Meyer and Barthel index scores were lower in the patients with the TT genotype relative to CT + CC genotypes (P < 0.01). These findings point to a role for VEGF polymorphism in HCH, and may be informative for future investigations on the pathogenesis of rehabilitative treatment.

Abstract
Brassica napus seed is a lipid storage organ containing approximately 40% oil, while its leaves contain many kinds of lipids for many biological roles, but the overall amounts are less than in seeds. Thus, lipid biosynthesis in the developing seeds and the leaves is strictly regulated which results the final difference of lipids. However, there are few reports about the molecular mechanism controlling the difference in lipid biosynthesis between developing seeds and leaves. In this study, we tried to uncover this mechanism by analyzing the transcriptome data for lipid biosynthesis. The transcriptome data were de novo assembled and a total of 47,216 unigenes were obtained, which had an N50 length and median of 1271 and 755 bp, respectively. Among these unigenes, 36,368 (about 77.02%) were annotated and there were 109 up-regulated unigenes and 72 down-regulated unigenes in the developing seeds lipid synthetic pathway after comparing with leaves. In the oleic acid pathway, 23 unigenes were up-regulated and four unigenes were down-regulated. During triacylglycerol (TAG) synthesis, the key unigenes were all up-regulated, such as phosphatidate phosphatase and diacylglycerol O-acyltransferase. During palmitic acid, palmitoleic acid, stearic acid, linoleic acid and linolenic acid synthesis in leaves, the unigenes were nearly all up-regulated, which indicated that the biosynthesis of these particular fatty acids were more important in leaves. In the developing seeds, almost all the unigenes in the ABI3VP1, RKD, CPP, E2F-DP, GRF, JUMONJI, MYB-related, PHD and REM transcript factor families were up-regulated, which helped us to discern the regulation mechanism underlying lipid biosynthesis. The differential up/down-regulation of the genes and TFs involved in lipid biosynthesis in developing seeds and leaves provided direct evidence that allowed us to map the network that regulates lipid biosynthesis, and the identification of new TFs that are up-regulated in developing seeds will help us to further elucidate the lipids biosynthesis pathway in developing seeds and leaves.

Abstract
Hypoxia inducible factor 2α (HIF-2α) can trigger the expression of several genes related to many aspects of tumor progress under hypoxia. As an independent factor, the role of HIF-2α is different from other hypoxia-mediated elements, including HIF-1α. Carbonic anhydrase (CA) were also regarded as important enzymes that involve in the tumor microenvironment pH. To find clinical-pathological features of breast cancer in plateau and explore the impact of CAIX, XII (CA-9, CA-12) and HIF-2α on patients with breast cancer. Clinical data were collected and summarized in 94 patients with breast cancer. The expression of HIF-2α, CA-9 and CA-12 were detected, using immunohistochemistry of specimens. The relation between expressions and clinical-pathology was analyzed. Under normoxia, hypoxia, and after being pretreated with the JNK inhibitor SP600125, HIF- 2α, CA-9 and CA-12 expressions were detected, and adhesion and invasion assays were performed in MCF-7 cells and HIF- 2α shRNA cells, respectively. There are higher expressions of HIF-2α in tumor classification 2 and clinical stage 2 (P < 0.05). High expression of CA-12 was observed in clinical stage 2 (P < 0.05). CA-9 expression is significantly correlated with CA-12 expression (r = 0.376, P = 0.0001). HIF-2α expression is not correlated with both CA-9 expression (P = 0.21) and CA-12 expression (P = 0.27). Breast cancer cells in vitro showed that HIF-2α, CA-9 or CA-12 had an increase expression under hypoxia (1% O2). CA-9 or CA-12 expression was observed in HIF-2α shRNA cells. JNK inhibitor SP 600125 reduced the HIF-2α expression and inhibited the adhesion and invasion of breast cancer cell. Slight inhibition effect on CA-9 and CA-12 expression was found. In conclusion, HIF-2α, CA-9 and CA-12 are important hypoxia responsive elements in breast cancer. HIF-2α was involved in metastasis and invasion of breast cancer cells under hypoxia, by the involvement of c-Jun NH2-terminal kinase (JNK) signal pathway. CA-9 and CA-12 may tend to be regulated by HIF-1α more often than by HIF-2α under hypoxia.

Abstract
The human adenovirus (HAdV) early protein E1B55K interacts with E4orf6 to form an E3 ubiquitin ligase complex, which plays key roles in virus replication. To illustrate the reason for the fastidiousness of HAdV-41 in 293 cells, interaction between heterotypic E1B55K and E4orf6 proteins was investigated. HAdV-5 E1B55K could interact with HAdV-41 E4orf6, and vice versa. To form E1B55K/E4orf6 E3 ubiquitin ligase, HAdV-41 E4orf6 recruited Cul2 while HAdV-5 E4orf6 interacted with Cul5. The ligase complex formed by HAdV-5 E1B55K and HAdV-41 E4orf6 could cause the degradation of p53 and Mre11. However, in E1-deleted HAdV-41-infected 293TE7 cells, which expressed HAdV-41 E1B55K, viral late mRNAs were exported from nucleus more efficiently and accumulated to a higher concentration in cytoplasm when compared with that in infected 293 cells. These results suggested that interaction between homotypic E1B55K and E4orf6 was indispensable for efficient export of viral late mRNAs.

Abstract
PURPOSE To explore the correlation of vascular risk factors for Alzheimer's disease (AD) in Chinese population. METHODS A total of 123 outpatients with probable AD followed up for 3 years were investigated. Severity of cognitive impairment and functional ability was assessed using Mini-Mental State Examination (MMSE) and modified activities of daily living (ADLs), respectively. The incidence of vascular risk factors was studied in patients with AD. RESULTS Univariate analysis showed significance difference in MMSE and ADL scores between patients with and without vascular risk factors (P < .05). Multiple regression analysis showed age, education, hyperhomocysteinemia, and hypertension were significant variables associated with annual MMSE, while there were no significant correlations between annual MMSE and sex, initial MMSE, diabetes, and so on. CONCLUSIONS Vascular risk factors are common comorbidities in patients with AD in China, with younger, better educated ones showing faster cognitive decline. Hypertension and hyperhomocysteinemia may also aggravate the progression, and it is important to prevent and treat patients with AD.

Abstract
A total of 288 crossbred (Duroc×Landrace×Yorkshire) growing pigs were used in two experiments to investigate the effects of adding β-mannanase to corn-soybean meal-based diets on pig performance and apparent total tract digestibility (ATTD). Both experiments lasted 28 d and were split into two phases namely 1 to 14 days (phase 1) and 15 to 28 days (phase 2). In Exp. 1,144 pigs weighing 23.60±1.59 kg BW were assigned to one of four corn-soybean meal-based diets containing 0, 200, 400 or 600 U/kg β-mannanase. Increasing the level of β-mannanase increased weight gain (quadratic effect; p<0.01) and feed efficiency (linear and quadratic effect; p<0.01) during the second phase and the overall experiment. However, performance was unaffected (p>0.05) by treatment during phase 1. Increasing the amount of β-mannanase in the diet improved (linear and quadratic effect; p<0.05) the ATTD of CP, NDF, ADF, calcium, and phosphorus during both phases. Based on the results of Exp. 1, the optimal supplementation level was determined to be 400 U/kg and this was the level that was applied in Exp. 2. In Exp. 2, 144 pigs weighing 23.50±1.86 kg BW were fed diets containing 0 or 400 U/kg of β-mannanase and 3,250 or 3,400 kcal/kg digestible energy (DE) in a 2×2 factorial design. β-Mannanase supplementation increased (p<0.01) weight gain and feed efficiency while the higher energy content increased (p<0.01) feed intake and feed efficiency during both phases and overall. Increased energy content and β-mannanase supplementation both increased (p<0.05) the ATTD of DM, CP, NDF, ADF, phosphorus, and GE during both phases. There were no significant interactions between energy level and β-mannanase for any performance or digestibility parameter. In conclusion, the β-mannanase used in the present experiment improved the performance of growing pigs fed diets based on corn and soybean. The mechanism through which the improvements were obtained appears to be related to improvements in ATTD.
