Abstract
Objective: To study the efficacy and safety of Balloon pulmonary angioplasty (BPA) for chronic thromboembolic pulmonary hypertension (CTEPH). Methods: Patients who were diagnosed CTEPH in China-Japan Friendship Hospital from Feb 2018 to Sep 2019 were evaluated. The ineligibility for pulmonary endarterectomy (PEA) and the indication for BPA were decided on the basis of a consensus among the multidisciplinary team for all CTEPH patients. 6-min walk distance (6MWD), the plasma level of N-terminal pro-brain natriuretic peptide (NT-proBNP), mixed venous oxygen saturation, mean pulmonary artery pressure (mPAP), cardiac index (CI) and pulmonary vascular resistance (PVR) were collected and analyzed before the first and the last BPA session. Results: A total of 67 BPA sessions were performed for 302 subsegmental pulmonary arteries in 25 inoperable CTEPH patients. 10 males (40.0%) and 15 females (60.0%), with the age of (57.8±7.1) years old. The median interval between CTEPH diagnosis and first BPA was 20.0 (9.0, 48.5) months. 18 patients were received more than 2 BPA sessions, the median follow-up time was 5.0 (3.5, 8.3) months. 6MWD, CI and the mixed venous oxygen saturation were significant improved after BPA [(425±74) vs (345±109) m, (1.99±0.45) vs (1.62±0.35) L·min(-1)·m(-2), (68.1%±6.5%) vs (61.2%±6.3%)](all P<0.05). The plasma level of NT-proBNP, mPAP and PVR were significantly decreased after BPA [259 (93, 739) vs 806 (148, 2 159) ng/L, (40.6±8.3) vs (47.3±10.7) mmHg (1 mmHg=0.133 kPa), (11.9±4.9) vs (17.2±6.5) WU (1 WU=80 dyn·s·cm(-5))](all P<0.05). Hemoptysis occurred in 5 sessions (7.5%) and reperfusion pulmonary edema (RPE) occurred in 2 sessions (1.5%), 1 patient needed non-invasive mechanical ventilation because of RPE, 1 patient died from right heart failure caused by hemoptysis during perioperative period. Conclusions: BPA can significantly improve the exercise tolerance and hemodynamic parameters for inoperable CTEPH patients, the risks of BPA are acceptable. BPA is an effective and relatively safe treatment for inoperable CTEPH patients.

Abstract
Objective: To investigate the clinical characteristics of patients with chronic thromboembolic pulmonary hypertension (CTEPH). Methods: CTEPH cases consecutively admitted into China-Japan Friendship Hospital from September 2015 to June 2019 were enrolled with prospective data collection. The medical histories, clinical characteristics, laboratory tests, imaging manifestation and hemodynamic parameters were analyzed. Patients were divided into high pulmonary vascular resistance (PVR) group and low PVR group according to the PVR level>1 000 dyn·s·cm(-5) or not, and clinical characteristics were compared between these two groups. Results: In the 148 cases of CTEPH, right heart catheterization was performed in 103 cases with mPAP (45.1±11.0) mmHg and PVR of (992±430) dyn·s·cm(-5). At diagnosis, 88 (59.5%) cases were in WHO functional class Ⅲ and 27 (18.2%) in class Ⅳ. Most common presenting symptoms were dyspnea (147, 99.3%), chest tightness (68, 45.9%), hemoptysis (42, 28.3%), syncope (30, 20.3%), and most common signs were P2 accentuation (95, 64.9%), edema (65, 43.9%), cyanosis (47, 31.8%), systolic murmur (44, 29.7%) and jugular vein distention (35, 23.6%). In 103 cases with right heart catheterization, 52 were in the low PVR group and 51 in high PVR group. Compared to the low PVR group, high PVR group patients had higher WHO functional class and more jugular vein distention (both P<0.05). In all the 148 cases, previous venous thromboembolism (VTE) was confirmed in 105 (70.9%) patients, with a higher prevalence of previous VTE in low PVR group than that in high PVR group (P<0.001). 30 (20.3%) patients had varicose veins of the lower extremities, and 21 (14.2%) had other thrombophilic disorders including antiphospholipid syndrome, protein C and S deficiency and antithrombin Ⅲ deficiency. Conclusions: Dyspnea, P2 accentuation and edema are the most common clinical presentation of CTEPH. Previous history of VTE is common in CTEPH patients with thrombophilia in some cases.

Abstract
Objective: To summarize the experience and effectivity of brain protection in 25 patients who suffered from chronic thromboembolic pulmonary hypertension (CTEPH) and received pulmonary thromboendarterectomy (PTE) under deep hypothermic circulatory arrest. Methods: Retrospective analysis of 25 PTE surgeries in our center from December 2016 to August 2018. All cases were completed underdeep hypothermic circulatory arrest. Standard brain protections were strictly executed, including: balanced and controlled extracorporeal circulation cooling, cerebral oxygen saturation (rSO(2)) monitoring, strictly control of circulatory arrest time, and etc. The neurological adverse events during the perioperative period were recorded and statistically analyzed, and the intelligence level and cognitive function of the patients were evaluated by MMSE scale and MoCA scale before surgery and discharge. Results: All the 25 patients successfully completed the surgery, and 1 patient (4%) died of postoperative infection. The mean pulmonary arterial pressure decreased from (52.9±16.7) mmHg before surgery to (23.6±8.1) mmHg immediately after surgery (t=10.01, P<0.01), and(20.7±7.9) mmHg at 3 months follow-up (t=10.73, P<0.01). Pulmonary vascular resistance decreased from 975.4 (788.6-1 292.8) dyn·s·cm(-5) to 376.1 (283.6-565.5) dyn·s·cm(-5) (Z=5.34, P<0.01). Neurological complications occurred in 3 patients during the perioperative period, including 2 patients with hypoxic encephalopathy, and 1 patient with cerebral hemorrhage. All 3 patients fully recovered before discharge. Univariate analysis showed that the duration of rSO(2)<40% and the maximum decrease rate of rSO(2) from baseline were significantly correlated with postoperative neurological damage. Multivariate analysis showed only time of rSO(2)<40% was significantly correlated with postoperative neurological damage. There was no significant difference in MMSE and MoCA score before and after surgery (P>0.05). Conclusions: Adequate brain protection measures are essential to reduce the neurological complications of PTE surgery. Real-time intraoperative monitoring of rSO(2) and strict control of circulatory arrest time can further reduce the occurrence of neurological damage.

Abstract
INTRODUCTION As the incidence of pediatric nephrolithiasis rises, understanding the efficacy and morbidity of surgical treatment options is critical. Currently, there are limited comparative data assessing shock wave lithotripsy (SWL) and ureteroscopy (URS) outcomes in children. OBJECTIVE The objective of this study was to compare stone clearance, 30-day emergency department visits, and the number of general anesthetics required per stone treatment for both modalities. STUDY DESIGN A multi-institutional retrospective review of children presenting for either URS or SWL between 2000 and 2017 was performed. Stone clearance, need for retreatment, the number of anesthetics, as well as the number and reason for emergency room visit were captured and compared between groups. Multivariate statistical analysis accounting for age, stone location, stone diameter, pre-intervention stent, and provider volume was performed for adjusted analysis. RESULTS A total of 84 SWL and 175 URS procedures were included. Complete stone clearance and rates of residual stone fragments <4 mm after final procedure for SWL were 77.0% and 90.8% and for URS were 78.5% and 91.7%, respectively. Retreatment rates for both procedures were not significantly different (17.9% SWL vs. 18.9% URS, P = 0.85). Children who underwent SWL had lower rates of emergency room visits for infections (0% vs. 5.1%, P = 0.03) and flank pain (3.6% vs. 10.9%, P = 0.05) and required fewer general anesthetics per treatment (1.2 vs. 2.0, P < 0.01) than those who underwent URS (Figure). DISCUSSION Stone clearance after both the initial and final treatments and need for repeat interventions were similar between surgical modalities. However, SWL carries less morbidity than URS. Specifically, patients who underwent SWL experienced lower rates of ED visits for urinary tract infection and for flank pain, parallel to conclusions in current comparative literature. In addition, SWL requires less general anesthetics (2.0 vs. 1.2), secondary to lower rates of ureteral stent placement and removal. Data on the potential risk of general anesthetics to neurodevelopment support thoughtful utilization of these medications. Limitations of this study include its retrospective nature and the prolonged 20-year time period over which data were collected. CONCLUSIONS When adjusting for confounders, SWL and URS achieve similar stone clearance. In the setting of equivalent efficacy, considerations regarding necessity of repeat interventions, morbidity of anesthesia, and complications should be integrated into clinical practice.

Abstract
Soil organisms represent the most biologically diverse community on land and govern the turnover of the largest organic matter pool in the terrestrial biosphere. The highly complex nature of these communities at local scales has traditionally obscured efforts to identify unifying patterns in global soil biodiversity and biogeochemistry. As a result, environmental covariates have generally been used as a proxy to represent the variation in soil community activity in global biogeochemical models. Yet over the past decade, broad-scale studies have begun to see past this local heterogeneity to identify unifying patterns in the biomass, diversity, and composition of certain soil groups across the globe. These unifying patterns provide new insights into the fundamental distribution and dynamics of organic matter on land.

Abstract
Background Expert groups have recommended incorporation of a geriatric assessment into clinical practice for older patients starting oncologic therapy. However, that practice is not standard primarily because of resource limitations. In the present study, we evaluated the effect on treatment decisions by oncologists in the community oncology setting of a brief geriatric assessment tool that estimates risk of toxicity. Methods This prospective longitudinal study in 5 community oncology practices in British Columbia involved patients 70 years of age and older starting a new cytotoxic chemotherapy regimen. Clinical personnel completed a brief validated geriatric assessment tool-the Cancer and Aging Research Group chemotherapy toxicity tool (carg-tt)-that estimates the risk of grade 3 or greater toxicity in older patients. Physicians were asked if the carg-tt changed their treatment plan or prompted extra supports. Patients were followed to assess the incidence of toxicity during treatment. Results The study enrolled 199 patients between July 2016 and February 2018. Mean age was 77 years. Treatment was palliative in 61.4% of the group. Compared with physician judgment, the carg-tt predicted higher rates of toxicity. In 5 patients, treatment was changed based on the carg-tt. In 38.5% of the patients, data from the tool prompted extra supports. Within the first 3 cycles of treatment, 21.3% of patients had experienced grade 3 or greater toxicity. Conclusions This study demonstrates that use of a brief geriatric assessment tool is possible in a broad community oncology practice. The tool modified the oncologist's supportive care plan for a significant number of older patients undertaking cytotoxic chemotherapy.

Abstract
BACKGROUND AND PURPOSE Fractional flow measured on 3D-TOF-MRA was proposed to quantify cerebral hemodynamic changes in patients with artery stenosis. We investigated the association between fractional flow and cerebral perfusion changes in patients with symptomatic MCA stenosis. MATERIALS AND METHODS This prospective study was approved by the institutional review board, and all participants provided written informed consent. From June 2015 to May 2018, four hundred twenty-nine patients with symptomatic intracranial arterial stenosis were consecutively recruited and underwent conventional brain MR imaging, 3D-TOF-MRA, and brain CTP. A total of 91 patients with unilateral M1 segment stenosis of the MCA and a stenosis degree of 50%∼99% were included in the analysis. Fractional flow was measured by comparing distal and proximal signal intensity changes across the stenosis on 3D-TOF-MRA. The cutoff value for fractional flow for discriminating between normal perfusion and hypoperfusion was obtained from the receiver operating characteristic curve. Associations between fractional flow and hypoperfusion were assessed using univariate and multivariate analyses. RESULTS The receiver operating characteristic curve showed a significant fractional flow threshold value at 0.90 (sensitivity, 70.1%; 95% CI, 55.9%-81.2%; specificity, 69.6%; 95% CI, 47.6%-84.1%). Participants with a fractional flow of ≤0.90 were independently associated with cerebral hypoperfusion downstream from the stenosis site (adjusted OR, 3.68; 95% CI, 1.63-11.62; P = .027). CONCLUSIONS Fractional flow measured on 3D-TOF-MRA may serve as a noninvasive and practical tool for determining the cerebral hypoperfusion in patents with symptomatic MCA stenosis.

Abstract
Objective: To analyze the clinical characteristics and explore the risk predictors on mortality in elderly patients with acute cholecystitis and cholangitis. Methods: We conducted a retrospective analysis of elderly patients hospitalized in the Second Medical Center of General Liberation Army Hospital for acute cholecystitis and cholangitis during 2000 to 2018. Clinical data and risk predictors on mortality were assessed. The patients were stratified into three groups based on age:Ⅰ (65-74 years old),Ⅱ (75-84 years old), and Ⅲ (≥85 years old). Logistic regression analysis was used to identify the predictors of mortality. Results: A total of 574 patients were finally enrolled with the mean age 87.6 years including 191 in group Ⅰ, 167 in group Ⅱ, and 216 in group Ⅲ. The main cause of acute cholecystitis and cholangitis was gallstone (76.3%),and the main symptom was abdominal pain (62.9%),followed by chills(62.5%),fever(59.8%),jaundice (47.2%) and septic shock(26.3%). Cholecystitis was the most common diagnosis in groups Ⅰ and Ⅱ,whereas it was cholangitis in group Ⅲ. Percutaneous transhepatic biliary/gallbladder drainage (PTBD/PTGD) and endoscopic retrograde cholangiopancreatography (ERCP) were administrated more frequently in groups Ⅲ. A total of 35 patients (6.1%) died during follow-up. Senior in age (OR=11.1),the Charlson comorbidity index (OR=19.5),cancers (OR=9.6),blood stream infections (OR=7.4),severity of cholecystitis and cholangitis (OR=4.2) were risk factors associated with mortality. Conclusions: Even in the elderly patients with acute cholecystitis and cholangitis,comorbidity is one of the main factors affecting clinical outcomes. Due to the poor performance, this group of population presents more severe disease and undergoes conservative treatment strategies.

Abstract
Objective: To evaluate the efficacy and safety of oral magnesium sulfate solution in split doses as bowel preparation in elderly patients undergoing colonoscopy. Methods: A total of 368 elderly patients undergoing colonoscopy were enrolled at PLA General Hospital. The patients were randomly divided into magnesium sulfate solution orally in split doses group (group A, n=178) and single dose group (group B, n=190). Parameters including general information, defecation frequency, Boston bowel preparation score (BBPS), detection rate of lesions and adverse reactions. Results: The frequency of defecations in group A was (7.6±1.4), more than that in group B (6.6±1.5) with statistical significance (P<0.05). The duration of bowel preparation in group A was (128.6±25.3) min, shorter than that of group B (165.4±29.7) min (P<0.05). The BBPS in group A was (8.09±0.67), better than that of group B (7.34±0.58) (P<0.05). The detection rates of intestinal polyps and micropolyps (diameter<0.5 cm) in group A were 73/178 (41.0%) and 51/178 (28.7%) respectively, compared with 58/190 (30.5%) and 37/190 (19.5%) in group B (both P<0.05). In group A, 8 patients reported adverse reactions as abdominal distension and discomfort. One patient had ST-T abnormality of electrocardiogram (ECG). No nausea or vomiting occurred, yet 2 cases needed enema for inadequate bowel preparation. Twenty-one cases in group B reported adverse events including 7 with nausea and vomiting. There were 13 patients treated with enema. Abnormal ECG was found in 4 patients in group B. The satisfaction rate of group A was 97.8%, higher than that of group B (91.6%) (P<0.05). Conclusions: The effect of bowel preparation of elderly patients with magnesium sulfate solution in split dose has a better tolerance, good cleaning effect and low incidence of adverse reactions. It is an ideal choice for the elderly to prepare colonoscopy.

Abstract
BACKGROUND The Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI) is a reliable outcome measure for cutaneous lupus erythematosus (CLE) in adults used in clinical trials. However, it has not been validated in children, limiting clinical trials for paediatric CLE. OBJECTIVES This study aimed to validate the CLASI in paediatrics. METHODS Eleven paediatric patients with CLE, six dermatologists and six rheumatologists participated. The physicians were trained to use the CLASI and Physician's Global Assessment (PGA), and individually rated all patients using both tools. Each physician reassessed two randomly selected patients. Within each physician group, the intraclass correlation coefficient (ICC) was calculated to assess the reliability of each measure. RESULTS CLASI activity scores demonstrated excellent inter- and intrarater reliability (ICC > 0·90), while the PGA activity scores had good inter-rater reliability (ICC 0·73-0·77) among both specialties. PGA activity scores showed excellent (ICC 0·89) and good intrarater reliability (ICC 0·76) for dermatologists and rheumatologists, respectively. Limitations of this study include the small sample size of patients and potential recall bias during the physician rerating session. CONCLUSIONS CLASI activity measurement showed excellent inter- and intrarater reliability in paediatric CLE and superiority over the PGA. These results demonstrate that the CLASI is a reliable and valid outcome instrument for paediatric CLE.

Abstract
BACKGROUND Routinely collected electronic health data obtained for administrative and clinical purposes are increasingly used to study atopic dermatitis (AD). Methods for identifying AD patients in routinely collected electronic health data differ, and it is unknown how this might affect study results. OBJECTIVES To evaluate how patients with AD have been identified in studies using routinely collected electronic health data, to determine whether these methods were validated and to estimate how the method for identifying patients with AD affected variability in prevalence estimates. METHODS We systematically searched PubMed, Embase and Web of Science for studies using routinely collected electronic health data that reported on AD as a primary outcome. Studies of localized AD and other types of dermatitis were excluded. The protocol for this review was registered in PROSPERO (CRD42016037968). RESULTS In total, 59 studies met eligibility criteria. Medical diagnosis codes for inclusion and exclusion, number of occasions of a code, type of provider associated with a code and prescription data were used to identify patients with AD. Only two studies described validation of their methods and no study reported on disease severity. Prevalence estimates ranged from 0·18% to 38·33% (median 4·91%) and up to threefold variation in prevalence was introduced by differences in the method for identifying patients with AD. CONCLUSIONS This systematic review highlights the need for clear reporting of methods for identifying patients with AD in routinely collected electronic health data to allow for meaningful interpretation and comparison of results.

Abstract
BACKGROUND AND PURPOSE Although flow diverters have been reported with favorable clinical and angiographic outcomes in various literatures, randomized trials determining their true effectiveness and safety are still in lack. The Parent Artery Reconstruction for Large or Giant Cerebral Aneurysms Using the Tubridge Flow Diverter (PARAT) trial was designed to evaluate the safety and efficacy of the Tubridge flow diverter in the treatment of large or giant aneurysms in comparison with Enterprise stent-assisted coiling. MATERIALS AND METHODS This prospective, multicenter, randomized trial was conducted at 12 hospitals throughout China. Enrolled adults with unruptured large/giant intracranial aneurysms were randomly assigned (1:1) to receive either Enterprise stent-assisted coiling or Tubridge flow diverter implantation. The primary end point was complete occlusion at 6-month follow-up, while secondary end points included technical success, mortality, target vessel-related stroke, aneurysm bleeding, in-stent stenosis, parent artery occlusion, and the frequency of all adverse events. RESULTS Among 185 enrolled subjects, 41 withdrew before procedure initiation. Overall, 82 subjects underwent Tubridge implantation, and 62 subjects were primarily treated with stent-assisted coiling. The results of 6-month follow-up imaging included complete occlusion rates of 75.34% versus 24.53% for the Tubridge and stent-assisted coiling groups, respectively, with a calculated common odds ratio of 9.4 (95% confidence interval, 4.14-21.38; P < .001). There was a higher, nonsignificant frequency of complications for Tubridge subjects. Multivariate analysis showed a decreased stroke rate at the primary investigational site, with a marginal P value (P = .051). CONCLUSIONS This trial showed an obviously higher rate of large and giant aneurysm obliteration with the Tubridge FD over Enterprise stent-assisted coiling. However, this higher obliteration rate came at the cost of a nonsignificantly higher rate of complications. Investigational site comparisons suggested that a learning curve for flow-diverter implantation should be recognized and factored into trial designs.

Abstract
Purpose Nuclear factor of activated T cells (NFAT) has been reported to be involved in the development of various types of cancer including adenocarcinoma of the breast. This research was the first to investigate NFAT protein expression in primary non-small cell lung cancer (NSCLC) tissues from Chinese patients. Methods NFAT protein expression was determined in 130 surgically resected primary NSCLC and matched normal tissues by immunohistochemical analysis. The association between NFAT expression and clinical categorical variables was further analyzed with the SPSS software. Results We found that NFAT expression was much higher in 85 tumor tissues (65.4%) and lower in 45 tumor tissues (34.6%) compared with the matched normal tissues. Further statistical analysis by the chi-square test showed that high expression of NFAT proteins was significantly associated with tumor differentiation (p=0.045), invasion (p=0.031), histology (p<0.0001), tumor size (p=0.038) and cigarette smoking history (p=0.024). However, there was no correlation between the expression of NFAT proteins and pTNM classification, and no difference in 5-year survival rate between patients with high or low expression of NFAT proteins. Multivariate logistic regression analysis for the correlation between NFAT protein expression levels and various characteristics showed a significant association with histology (p=0.008, OR=0.273). Conclusion Our results revealed that high NFAT expression was present in Chinese NSCLCs and that NFAT expression might be involved in the process of human lung cancer development.

Abstract
Severe fever with thrombocytopenia syndrome virus (SFTSV) is a newly identified Phlebovirus that causes severe fever with thrombocytopenia syndrome. Our study demonstrated that SFTSV NSs functioned as IFN antagonist mainly by suppressing TBK1/IKKε-IRF3 signaling pathway. NSs interacted with and relocalized TANK-binding kinase 1 (TBK1) into NSs-induced cytoplasmic structures and this interaction could effectively inhibit downstream phosphorylation and dimerization of interferon regulatory factor 3 (IRF3), resulting in the suppression of antiviral signaling and IFN induction. Functional sites of SFTSV NSs binding with TBK1 were then studied and results showed that NSs had lost their IFN-inhibiting activity after deleting the 25 amino acids in N-terminal. Furthermore, the mechanism of Rift Valley fever virus (RVFV) NSs blocking IFN-β response were also investigated. Preliminary results showed that RVFV NSs proteins could neither interact nor co-localize with TBK1 in cytoplasm, but suppressed its expression levels, phosphorylation and dimerization of IRF3 in the subsequent steps, resulting in inhibition of the IFN-β production. Altogether, our data demonstrated the probable mechanism used by SFTSV to inhibit IFN responses which was different from RVFV and pointed toward a novel mechanism for RVFV suppressing IFN responses.

Abstract
Evidence indicates that after brain injury, neurogenesis is enhanced in regions such as hippocampus, striatum, and cortex. To study the role of hypoxia-inducible factor-1 (HIF‑1α) and Wnt signaling in cerebral ischemia/hypoxia-induced proliferation of neural stem cells (NSCs), we investigated the proliferation of NSCs, expression of HIF‑1α, and activation of Wnt signaling under conditions of pathologic hypoxia in vitro. NSCs were isolated from 30-day-old Sprague-Dawley rats and subjected to 0.3% oxygen in a microaerophilic incubation system. Cell proliferation was evaluated by measuring the diameter of neurospheres and by bromodeoxyuridine incorporation assays. Real-time quantitative PCR and Western blotting were used to detect mRNA and protein levels of HIF-1α, β-catenin, and cyclin D1 in the NSCs. The results showed that hypoxia increased NSC proliferation and the levels of HIF-1α, β‑catenin, and cyclin D1 (p < 0.05). Blockade of the Wnt signaling pathway decreased hypoxia-induced NSC proliferation, whereas activation of this pathway increased hypoxia-induced NSC proliferation (p < 0.05). Knockdown of HIF-1α with HIF-1α siRNA decreased β‑catenin nuclear translocation and cyclin D1 expression, and inhibited proliferation of NSCs (p < 0.05). These findings indicate that pathologic hypoxia stimulates NSC proliferation by increasing expression of HIF-1α and activating the Wnt/β-catenin signaling pathway. The data suggest that Wnt/β-catenin signaling may play a key role in NSC proliferation under conditions of pathologic hypoxia.

Abstract
Oryza longistaminata originates from African wild rice and contains valuable traits conferring tolerance to biotic and abiotic stress. However, interspecific crosses between O. longistaminata and Oryza sativa cultivars are hindered by reproductive barriers. To dissect the mechanism of interspecific hybrid sterility, we developed a near-isogenic line (NIL) using indica variety RD23 as the recipient parent and O. longistaminata as the donor parent. Both pollen and embryo sac semi-sterility were observed in F1 hybrids between RD23 and NIL. Cytological analysis demonstrated that pollen abortion in F1 hybrids occurred at the early bi-nucleate stage due to a failure of the first mitosis in microspores. Partial embryo sacs in the F1 hybrids were defective during the functional megaspore formation stage. Most notably, nearly half of the male or female gametes were aborted in heterozygotes S40iS40l, regardless of their genotypes. Thus, S40 was indicated as a one-locus sporophytic sterility gene controlling both male and female fertility in hybrids between RD23 and O. longistaminata. A population of 16 802 plants derived from the hybrid RD23/NIL-S40 was developed to fine-map S40. Finally, the S40 locus was delimited to an 80-kb region on the short arm of chromosome 1 in terms with reference sequences of cv. 93-11. Eight open reading frames (ORFs) were localized in this region. On the basis of gene expression and genomic sequence analysis, ORF5 and ORF8 were identified as candidate genes for the S40 locus. These results are helpful in cloning the S40 gene and marker-assisted transferring of the corresponding neutral allele in rice breeding programs.

Abstract
OBJECTIVE This study sought to explore endothelial nitric oxide synthase (eNOS) expression in acute pulmonary thromboembolism (APE). MATERIALS AND METHODS eNOS expression in lung tissue and bone marrow-derived endothelial progenitor cells (BM-EPCs) from APE mouse models was assessed by immunohistochemistry and real-time PCR. A gene expression profile meta-analysis was performed on human venous thromboembolism (VTE) whole blood samples recorded in the Gene Expression Omnibus (GEO) repository. Significantly expressed genes were determined from the microarray data by unsupervised clustering and supervised classification. Selected sample data with significantly expressed genes were further analyzed by principal component analysis (PCA), followed by Bayesian probit regression. Key discriminate genes were further grouped and annotated using functional annotations and gene enrichments using the online Database for Annotation, Visualization and Integrated Discovery (DAVID) software (v. 6.7). RESULTS While eNOS expression was significantly higher, serum nitric oxide levels were significantly lower in APE mice (20.42 ± 2.15 μM) compared to controls (53.50 ± 5.69 μM, p<0.001). eNOS mRNA and protein levels were significantly upregulated in BM-EPCs from APE mice. GEO repository data reported 3,397 upregulated and 4,173 downregulated genes (including eNOS) in VTE patients. In this regression analysis, the significant principal component PC1 and PC2 (p<0.05) were useful in distinguishing the VTE classification. The coefficient value of eNOS was -0.47707 in PC1 and -0.08429 in PC2, which did have some proportions on these significantly discriminated components but did not contribute significantly to the VTE classification. Functional enrichment in terms of acetylation and phosphoproteins were high. CONCLUSIONS Our findings, therefore, suggest that expression of eNOS is significantly altered in APE and may be a potential peripheral blood biomarker. Modulation of eNOS expression may be used for APE treatment.

Abstract
Prostate cancer (Pca) is one of the most common types of cancer for elder men. Aberrant expression of epidermal growth factor receptor (EGFR) and EGFR downstream signaling have been known to contribute to disease progression in prostate cancer. EGF-stimulated EGFR is internalized and the process of endocytic degradation of EGFR mediates its signaling which is frequently dysregulated in many kinds of cancer. In the present study, we demonstrated that endophilin B1 expression was inhibited and EGFR expression was significantly increased in prostate cancer cell lines. We demonstrated that suppression of endophilin B1 increased EGFR levels via delaying EGFR internalization triggered by EGF and its intracellular degradation. Endophilin B1 decreased also sustained EGFR downstream signaling such as Erk1/2 phosphorylation in response to EGF stimulation and promoted prostate cancer cell proliferation which is EGF independent. Our data indicated that endophilin B1 mediated the biological function of EGFR in cancer cell proliferation through regulating the EGFR endocytic trafficking and downstream signaling.

Abstract
MicroRNAs (abbreviated miRNAs) have been demonstrated to be involved in tumorigenesis and cancer development and proposed as promising biomarkers in cancer diagnosis. Numerous studies have observed the aberrant expression of miRNAs in esophageal cancer. However, there are some discrepant results. Thus, we conducted this meta-analysis to identify the overall accuracy of miRNAs in the diagnosis of esophageal cancer. A comprehensive literature search was conducted in PubMed and other databases using combinations of key words. The summary receiver operator characteristic curves were plotted to assess the overall diagnostic performance of miRNAs. Chi-squared and I(2) tests were used to assess the heterogeneity between studies. Additionally, we conducted subgroup and sensitivity analyses to analyze the potential sources of heterogeneity. In total, 33 studies from 12 articles were available in this meta-analysis. The pooled sensitivity, specificity, positive and negative likelihood ratio (PLR, NLR) diagnostic odds ratio, and area under the curve were 0.80, 0.80, 4.0, 0.25, 16, and 0.87, respectively. Subgroup analyses based on the sample types (saliva-, serum- and plasma-based) showed no differences in the diagnostic accuracy of each subgroup. An independent meta-analysis of eight articles was conducted to evaluate the diagnostic accuracy of miRNAs in patients with esophageal squamous cell carcinoma, with a pooled sensitivity of 0.77, specificity of 0.83, PLR of 4.4, NLR of 0.27, diagnostic odds ratio of 16, and area under the curve of 0.87. In conclusion, this meta-analysis demonstrates the feasibility of using miRNAs as non-invasive biomarkers to discriminate esophageal cancer from healthy controls. However, further high-quality studies on more clearly defined esophageal cancer patient are needed to confirm our conclusion.
