Abstract
AIM To evaluate the clinical usefulness of quantitative dual-energy (DE) computed tomography (CT) iodine enhancement metrics combined with morphological CT features in distinguishing small-cell lung cancer (SCLC) from non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS One hundred and six untreated lung cancer patients who underwent DECT before biopsy or surgery were prospectively enrolled. Twenty-seven routine CT descriptors, including tumour location, size, shape, margin, enhancement heterogeneity, and internal and surrounding structures, and associated findings were assessed and DECT parameters were measured in all patients. Multiple logistic regression analyses were applied to identify independent predictors of SCLC. The area under the receiver operating characteristic curve was compared between CT features combined with DECT metrics and CT features alone for distinguishing SCLC from NSCLC. RESULTS Histology revealed NSCLC in 80 and SCLC in 26 patients. In univariate analysis, 12 morphological CT features and two DECT metrics differed significantly between NSCLC and SCLC. When DECT parameters were combined with CT features for multivariate analysis, the independent predictors of SCLC were large tumour size, central location, confluent mediastinal lymphadenopathy, homogeneous enhancement, absence of coarse spiculation, and lower iodine density and iodine ratio (all p<0.05). The area under the receiver operating characteristic curve was improved from 0.908 to 0.981 after adding DECT metrics compared with CT features alone (p=0.007). CONCLUSION The combination of DECT measures and CT morphological features can be used to distinguish SCLC from NSCLC, with higher diagnostic performance compared with CT morphological features alone.

Abstract
It is challenging to quantify the geometrically necessary dislocation (GND) density at the nanoscale using conventional electron backscatter diffraction due to its limited spatial resolution. To overcome this problem, in this study, the transmission Kikuchi diffraction (TKD) technique is used to measure lattice orientation and to calculate the corresponding nanoscale GND density. Using the TKD method, a variation of GND density from 6 × 1014 to 1016 m-2 has been measured in a welded super duplex stainless steel sample. The distribution of dislocation density is shown to be in good agreement with transmission electron microscope (TEM) result. Compared with dislocation measurements obtained by TEM, the TKD-GND method is revealed to be a relatively accurate, fast and accessible method.

Abstract
Objectives The aim of this study is to investigate the sex-specific aortic root anatomy in patients with bicuspid aortic valve (BAV). Patients and methods This retrospective study includes 73 consecutive patients with BAV who underwent CT evaluation before transcatheter aortic valve replacement (TAVR) between July 2013 and April 2017 in the Second Affiliated Hospital of Zhejiang University. Result The size of the annulus, diameter and height of the sinotubular junction (STJ), height of the coronary artery ostia, and dimension of the aorta were measured. Women had significantly smaller annulus parameters (mean diameter: 23.4 ± 1.8 vs. 26.1 ± 2.1 mm; area: 425.3 ± 59.4 vs. 527.4 ± 84.6 mm2; perimeter: 74.3 ± 5.2 vs. 83.2 ± 6.4 mm), and STJ diameter (29.7 ± 3.1 vs. 32.6 ± 4.5 mm) than men (p < 0.01 for all), even after adjustment for their smaller body surface area (BSA). Dimension of aorta and height of right coronary artery were also significantly smaller in women, although not when indexing for the BSA. The left ventricular ejection fraction of women is significantly higher than that of men before discharge (60.2 ± 9.7% vs. 53.7 ± 13.6%, p = 0.01). There were no differences between women and men in the all-cause 30-day and 1‑year mortality. Conclusion Women with BAV had smaller annulus and STJ diameter after indexing for BSA, reflecting a sex-specific difference. There were no differences in 30-day and 1‑year mortality between the two groups.

Abstract
Objective: To analyze the related factors of diabetic nephropathy in inpatients with type 1 diabetes mellitus (T1DM). Methods: A total of 300 patients with T1DM who were treated in the Department of Endocrinology of Anhui Provincial Hospital between 2014 and 2016 were analyzed retrospectively. All the patients were divided into two groups according to their urine albumin-to-creatinine ratio: non-diabetic nephropathy group (n=193) and diabetic nephropathy group (n=107). Multivariate logistic regression analysis was adopted to analyze the factors related to diabetic nephropathy in T1DM, including the age, diabetic duration, body mass index (BMI) and glycosylated hemoglobin (HbA1c) of the two groups. Results: Age, diabetes duration, HbA1c, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol, triglyceride and uric acid (UA) of diabetic nephropathy group were higher than those of non-diabetic nephropathy group (all P<0.05). The total bilirubin, hemoglobin (Hb) and albumin in non-diabetic nephropathy group were higher than those in diabetic nephropathy group (P<0.05). The proportion of women in diabetic nephropathy group was higher than non-diabetic nephropathy group (62.6% vs 42.0%, P=0.001). Multivariate logistic regression analysis showed that diabetes duration (OR=2.142, 95% CI: 1.011-4.539), HbA1c (OR=1.262, 95% CI: 1.090-1.462), DBP (OR=1.048, 95% CI: 1.001-1.096), UA (OR=1.005, 95% CI: 1.001-1.009) and Hb (OR=0.952, 95% CI: 0.929-0.975) were independent related factors for diabetic nephropathy. Conclusions: Positive controlling of blood pressure, blood glucose, hyperuricemia and correcting anemia may reduce the incidence of diabetic nephropathy in T1DM patients.

Abstract
Suppressor of cytokine signalling (SOCS) proteins are crucial negative regulators in many signalling pathways and are implicated in the pathogenesis of infectious diseases. The purpose of this study was to uncover possible associations of common polymorphisms within SOCS genes with infectious outcomes after traumatic injury. A total of 1087 trauma patients (Chongqing cohort 806 and Yunnan cohort 281) were recruited and followed-up for the development of infectious outcomes, such as sepsis and multiple organ dysfunction syndrome (MODS). Twelve selected single nucleotide polymorphisms (SNPs) were screened by pyrosequencing to determine their genotypes and associations with infectious complications. Among the 12 selected SNPs, only the cytokine-inducible Src homology (SH2) domain protein (CISH) promoter rs414171 polymorphism was found consistently to be associated statistically with the incidence of sepsis and MOD score in the two cohorts, despite analysing the SNPs independently or in combination. Further, patients with a T allele had significantly lower CISH expression and lower production of tumour necrosis factor (TNF)-α, but higher production of interleukin (IL)-10. Luciferase assay confirmed that the A→T variant in the rs414171 polymorphism inhibited the transcriptional activities of the CISH gene significantly. The CISH rs414171 polymorphism is associated significantly with susceptibility to sepsis and MODS in traumatic patients, which might prove to be a novel biomarker for indicating risk of infectious outcomes in critically injured patients.

Abstract
OBJECTIVE To investigate the effects of glucose metabolism, insulin resistance, and inflammatory factors on International Prostatic Symptom Score (IPSS) of patients with benign prostatic hyperplasia (BPH), to explore their correlations and evaluate the clinical significance. PATIENTS AND METHODS 90 patients with BPH were selected and divided into normal blood glucose group and abnormal blood glucose group. The changes of indexes related to prostate function, prostate volume (PV), prostate-specific antigen (PSA), and IPSS in two groups were evaluated. The fasting blood glucose (FBS), fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR) index and inflammatory factors interleukin-8 (IL-8) and cyclooxygenase 2 (COX-2) levels in expressed prostatic secretion (EPS) were compared. The correlations of glucose metabolism, insulin resistance and inflammatory factors with IPSS were analyzed by Logistic regression. The changes of these indexes after treatment of BPH were observed. RESULTS The FBS, FINS, HOMA-IR, and inflammatory factors IL-8 and COX-2 levels were significantly different between high IPSS group and low IPSS group of patients with BPH. Moreover, the PV and PSA were higher in high IPSS group than those in low IPSS group. The FBS, FINS and inflammatory factors IL-8 and COX-2 levels were positively correlated with IPSS (p<0.05). All the indexes above of BPH patients were decreased after treatment. CONCLUSIONS The FBS, FINS, and inflammatory factors IL-8 and COX-2 levels are closely correlated with IPSS, which can reflect the severity and prognosis of BPH. It can effectively postpone the progression of BPH by lowering blood glucose, improving insulin resistance, and controlling the expressions of inflammatory factors in serum through a healthy lifestyle and clinical comprehensive treatment.

Abstract
Xanthogranulomatous pyelonephritis (XGP) is an unusual form of chronic pyelonephritis in which the renal parenchyma is destroyed and replaced by lipid-laden foamy macrophages. It usually affects middle-aged women with a history of recurrent urinary tract infection, diabetes, or kidney stones. The inflammatory process is usually diffuse and can extend beyond the kidney. The rare focal forms may simulate primary renal tumours. The preoperative imaging diagnosis may be difficult. We reported five cases of XGP, The findings of ours were recorded including kidney size, shape, contour, the echogenecity of the renal parenchyma, the internal echoes of the dilate collecting system, the presence of perinephric fluid accumulation and obstruction. One of the 5 cases was a male patient, and the other four were female, with a mean age of 53 years. He affected kidneys of the 5 cases swelled in different degrees, and one of them was found with line-like anechoic fluid. Among the 5 cases, one kidney appeared as diffusely reducing of the parenchyma echogenicity, multiple hypoechoic areas, disappearance of corticomedullary differentiation and multiple hyperecho with shadow. A round cystic anechoic lesion was found in one kidney, with internal punctate echo and peripheral fluid. Ultrasonographic finding of 1 case was extremely hypoechoic lesion on the left kidney, protruding from the outline of the kidney, with the partial renal capsule discontinuous, the less clear boundary, and a little blood flow in it. Ultrasonographic demonstration of 2 cases was mild dilatation of the collecting system with irregular wall thickening and internal hypoechogenicity, and 1 case was solid lesion with less clear boundary to the pelvic wall and a small amount of blood flow signal, the another 1 case was showed floccule without internal blood flow. Three cases were caused by chronic obstruction verified by operation, of which one was staghorn calculi, one was poorly differentiated squamous cell carcinoma in the middle part of the ureter, and one was inflammatory stricture of upper ureteral. Through analysis of the above five cases and review of related literature, we explored diagnoses and management of the patients with XGP. Xanthogranulomatous pyelonephritis (XGP) is a rare chronic variant of pyelonephritis characterized by destruction of the renal parenchyma. Combining ultrasonographic features of XGP with clinical recurrent urinary infection and chronic obstruction, XGP can be included in the differentiation. The diagnosis of XGP suspected by ultrasound can be clarified by CT, MRI, contrast-enhanced ultrasound.

Abstract
OBJECTIVES This study aimed to examine how social development influenced life expectancy from a spatio-temporal perspective. STUDY DESIGN Data were taken from the China Statistical Yearbooks for 2001 and 2011, which presented results from 2000 to 2010, respectively. METHODS A geographically weighted regression method was performed. A total of 31 provinces were treated as units of our analysis, and four social development dimensions were extracted by exploratory factor analysis. RESULTS Generally speaking, healthcare and education development could significantly improve life expectancy. Between 2000 and 2010, the positive effects of social harmony and eco-environment development were gradually increasing. Spatially speaking, the enhancing effect of healthcare development on life expectancy generally declined from south to north China; the improving effect of education development generally declined from southwest China to northeast and northwest China. The geographical distributions of the effects of eco-environment and social harmony development on life expectancy were different between 2000 and 2010; the former declined from the eastern coast to west China in 2000 and declined from northwest to south China in 2010, while the latter first declined from north to southwest China in 2000 and then declined from southwest to northeast China in 2010. CONCLUSIONS Because the effects of various social development dimensions on life expectancy vary with time and space, it is necessary to improve certain aspects of social development in specific areas and social stages to efficiently improve life expectancy and population health.

Concordance between quantitative trait locus genotype as determined by the a posteriori granddaughter design and marker genotype was determined for 30 trait-by-chromosomal segment effects segregating in the US Holstein population with probabilities of <10-20 to accept the null hypotheses of no segregating gene affecting the trait within the chromosomal segment. Genotypes for 83 grandsires and 17,217 sons were determined by either complete sequence or imputation for 3,148,506 polymorphisms across the entire genome; 471 Holstein bulls had a complete genome sequence, including 64 of the grandsires. Complete concordance was obtained only for stature on chromosome 14 and daughter pregnancy rate on chromosome 18. For each quantitative trait locus, effects of the 30 polymorphisms with highest concordance scores for the analyzed trait were computed by stepwise regression for predicted transmitting abilities of 26,750 bulls with progeny test and imputed genotypes. Effects for stature on chromosome 11, daughter pregnancy rate on chromosome 18, and protein percentage on chromosome 20 met 3 criteria: complete or almost complete concordance, nominal significance of the polymorphism effect after correction for all other polymorphisms, and marker coefficient of determination >40% of total multiple-regression coefficient of determination for the 30 polymorphisms with highest concordance. An intronic variant marker on chromosome 5 at 93,945,738 bp explained 7% of variance for fat percentage and 74% of total multiple-marker regression variance but was concordant for only 24 of 30 families. The missense polymorphism Phe279Tyr in GHR at 31,909,478 bp on chromosome 20 was confirmed as the causative mutation for fat and protein concentration. For effect on fat percentage on chromosome 14, 12 additional missense polymorphisms were found that had almost complete concordance with the suggested causative polymorphism (missense mutation Ala232Glu in DGAT1). The only polymorphism found likely to improve predictive power for genomic evaluation of dairy cattle was on chromosome 15; that polymorphism had a frequency of 0.45 for the allele with economically positive effects on all production traits.

Abstract
We report on the depletion and power amplification of the driving laser pulse in a strongly driven laser wakefield accelerator. Simultaneous measurement of the transmitted pulse energy and temporal shape indicate an increase in peak power from 187±11 TW to a maximum of 318±12 TW after 13 mm of propagation in a plasma density of 0.9×10^{18} cm^{-3}. The power amplification is correlated with the injection and acceleration of electrons in the nonlinear wakefield. This process is modeled by including a localized redshift and subsequent group delay dispersion at the laser pulse front.

Abstract
BACKGROUND The effects of H4 R antagonists in preclinical asthma models support the study of antagonists of the H4 R in the treatment of asthma in humans. JNJ-39758979 is a potent and highly selective oral H4 R antagonist. OBJECTIVE We sought to evaluate the safety and efficacy of the H4 R-antagonist JNJ-39758979 in adult patients with uncontrolled asthma. METHODS One hundred and fifteen eligible patients were randomly assigned to JNJ-39758979 300 mg or placebo once daily for 12 weeks in this phase 2a, double-blind, multicenter, placebo-controlled study. Primary efficacy was assessed via week-12 change from baseline in pre-bronchodilator forced expiratory volume in 1 second (FEV1 ). Secondary efficacy assessments included patient-reported outcome (PRO) asthma assessments (Asthma Daily Diary data [AM and PM peak expiratory flow rate, number of puffs of albuterol/salbutamol, the presence of nocturnal awakenings and asthma symptom score]). RESULTS The study did not meet the primary end-point. However, nominally significant improvements in pre-bronchodilator FEV1 were observed with JNJ-39758979 versus placebo at week 12 in pre-specified subgroups with elevated exhaled nitric oxide, sputum eosinophils or blood eosinophils at baseline. Nominally significant improvements across PRO assessments were consistently observed in the overall population, as well as in eosinophilic subgroups. Safety, such as adverse event rates, was comparable between JNJ-39758979 and placebo. No serious adverse events were reported. No clinically relevant changes in laboratory values were observed. CONCLUSIONS AND CLINICAL RELEVANCE The findings suggest potential benefit of H4 R antagonists on lung function and asthma control in eosinophilic asthma patients and warrant further evaluation of this mechanism in asthma with eosinophilic inflammation. NCT00946569.

Abstract
AIM To evaluate the correlation between miRNA-375 and cell proliferation and apoptosis in glioma cancer cell. METHODS Collecting 30 cases of glioma cancer patients and 30 cases of cerebral infarction patients. The miRNA-375 and CTGF protein expressions were evaluated by ISH and IHC methods. In the cell experiment, the U87 cells were divided into 3 groups: NC group (the cells were treated with normal method); BL group (the cells were transfected with empty vector) and miRNA group (the cells were transfected with miRNA-375). The U87 cell proliferation and apoptosis rates and cell cycle of the different groups were measured by MTT and flow cytometry. The relative proteins (CTGF, EGFR, AKT, Erk and P21) expressions were measured by WB assay. RESULTS The miRNA-375 and CTGF expressions of glioma cancer tissues were significantly different compared with those of no-cancer tissues (p < 0.05, respectively). In the cell experiments, the cell proliferation of miRNA group was significantly decreased compared with that of NC group (p < 0.05); the cell apoptosis and G1 phase rate of miRNA group was significantly decreased compared with NC group (p < 0.05, respectively). Depending on the WB assay, the CTGF, EGFR, AKT, Erk and P21 proteins expressions of miRNA group were significantly different compared with proteins expressions of NC group (p < 0.05, respectively). CONCLUSION miRNA-375 over-expression suppresses glioma cancer cells development via CTGF-EGFR pathway (Fig. 3, Ref. 30).

Abstract
Head and neck squamous cell carcinoma (HNSCC) is the sixth common malignant tumors of whole body with a high incidence, which accounts for 90% of the head and neck malignant tumors. Previous studies have shown the risk factors, such as tobacco and alcohol, are related to the occurrence and development of HNSCC. However, recent studies have shown that the non-tobacco and non-alcohol related HNSCC increased year by year. At the same time, more and more studies have shown that HNSCC is related to the infection with human papilloma virus (HPV), and the occurrence and development of HPV-positive HNSCC has own characteristics in epidemiology, pathogenesis, treatment and prognosis. In this paper the research progress for HPV-positive HNSCC is reviewed.

Abstract
Objective: To evaluate the difference of plasma myeloperoxidase (MPO) level in different types of acute coronary syndrome (ACS) patients, and the value of baseline MPO level in predicting short-term and long-term outcomes in patients with ACS. Methods: The study cohort was derived from "the 12th Five-Year" National Science and Technology Support Program Project "Study on Comprehensive Intervention and Prognosis of Acute Coronary Syndrome" . We enrolled all hospitalized ACS patients who were enrolled in "the 12th Five-Year" cohort from January 1, 2011 to December 31, 2013. A total of 630 patients from 20 centers were enrolled. According to the diagnosis, the patients were divided into two groups: ST-segment elevation myocardial infarction (STEMI) group and non-ST-elevation acute coronary syndrome (NSTE-ACS) group. Plasma levels of MPO were measured by ELISA method. Cardiovascular events in the hospital were recorded. All patients were followed-up by telephone, follow-up ended December 31, 2015. The occurrence of major adverse cardiovascular events (MACE, defined as cardiac death, recurrent myocardial infarction, unscheduled coronary revascularization procedure and stroke) and all-cause death were recorded. Logistic regression analysis and Cox regression analysis were used to evaluate the predictive value of baseline MPO levels obtained during hospitalization and the long-term outcomes of ACS patients. Results: A total of 597 ACS patients were enrolled in final analysis. Level of plasma MPO in STEMI patients was significantly higher than that of NSTE-ACS patients (34.02(19.31, 67.87) μg/L vs. 27.25(16.69, 52.92) μg/L, P=0.028) . MPO was not related to the in-hospital cardiovascular events (OR=0.797, 95%CI 0.366-1.737, P=0.569). Follow up was completed in 476 patients, median follow-up time was 796 (32, 1 816) days. There were 23 all-cause deaths and 51 MACE. Plasma MPO level was not an independent predictor for all-cause death (HR=1.434, 95%CI 0.502-4.100, P=0.501) and MACE (HR=1.271, 95%CI 0.662-2.442, P=0.471). Conclusion: In hospitalized ACS patients, level of plasma MPO was significantly higher in STEMI patients than in NSTE-ACS patients, but MPO could not predict the short-term or long-term outcomes in patients with ACS.

Abstract
OBJECTIVE Talaromyces marneffei is an opportunistic infection with high morbidity among human immunodeficiency virus (HIV)/AIDS patients in Southeast Asia and southern China. Its effects on mortality in HIV/AIDS patients has not been clearly elucidated. METHODS We conducted a retrospective cohort study of hospitalized HIV-infected individuals at the Fourth People's Hospital of Nanning, Guangxi, China during 2012-2015. Kaplan-Meier analyses were used to calculate the cumulative mortality. Cox proportional hazard models and 1:1 propensity score matching (PSM) were used to evaluate the effects of T. marneffei infection on mortality of HIV/AIDS patients. RESULTS In total, 6791 HIV/AIDS patients were included, 1093 of them (16.1%) with documented T. marneffei co-infection. The mortality of T. marneffei-infected patients (25.0 per 100 person-months, 95% CI 21.5-26.7) was the highest among all AIDS-associated complications and was significantly higher than that of T. marneffei-uninfected HIV/AIDS patients (13.8 per 100 person-months, 95% CI 12.5-15.1; adjusted hazard ratio (AHR) 1.80, 95% CI 1.48-2.16). The results using PSM were similar (AHR 4.52 95% CI 2.43-8.42). The mortality of T. marneffei-infected patients was also significantly higher than that of patients without any complications. When stratified by demographic characteristics, T. marneffei infection has higher mortality risk in all stratifications. Co-infection with T. marneffei carries a higher mortality risk in patients at any CD4+ T-cell count. CONCLUSIONS Talaromyces marneffei infection is commonly found in hospitalized HIV/AIDS patients in southern China and was associated with a higher mortality rate than most HIV-associated complications. These results highlight the need for improved diagnosis, treatment and prevention of infection by this neglected fungal pathogen in southern China.

Abstract
Fires resulting from titanium combustion are complex and violent processes which can instantly burn a titanium alloy once ignited. The occurrence of titanium combustion is a disaster for aircraft. Accurate measurement of the ignition temperature of titanium alloys is of significance in preventing such fires and in investigating combustion-resistance properties. In this study, monochromatic temperature and emissivity measurement methods based on reflectivity detection were used to determine the ignition temperature of a titanium alloy. Experiments were carried out using a titanium burning apparatus. The temperatures of titanium in the oxidation stage before ignition and in the combustion stage during the ignition process were measured using wavelengths of 1050 nm and 940 nm, respectively. Experimental results showed that the ignition temperature of the titanium alloy could be measured by reflectivity detection and that measurement precision during thermal oxidation (500-900 °C) was ±1 °C. The temperature of the ignition process ranged between 1653 and 1857 °C, and the ignition temperature was around 1680 °C.

Abstract
OBJECTIVE To comprehensively examine the correlation between body mass index (BMI) and the risk of new-onset diabetes after kidney transplantation (NODAT). METHODS The electronic databases Pubmed, Embase, and Cochrane Library, updated in December 2016, were searched, and a literature review was conducted as well to identify relevant research studies. With the use of R 3.12 software, the association between BMI and NODAT risk was analyzed by means of a meta-analysis, with the mean differences (MDs) and their 95% confidence intervals (CIs) as effect indexes. Publication bias was assessed with the use of the Egger test. A sensitivity analysis was performed by excluding 1 study at a time. And the overall morbidity of NODAT was calculated. RESULTS In the meta-analysis, 55 eligible studies involving 15,458 kidney transplantation cases were included. After the heterogeneity test, the random-effects model was used to calculate the pooled results of the effect indexes. The results of the meta-analysis showed that BMI was an independent risk factor of NODAT (MD, 1.88; 95% CI, 1.48-2.27). No publication bias was found among the included studies (t = 0.3417; P = 0.7339). The sensitivity analysis revealed that the pooled MD did not reverse after ignoring 1 study at a time. In addition, the overall morbidity of NODAT was 21% (95% CI, 21%-23%). CONCLUSIONS Our results suggest that BMI is an independent risk factor for NODAT.

Abstract
Melasma is a common disorder of hyperpigmentation characterized by tan or brown macules and patches affecting sun-exposed areas, particularly the face. Melasma has been shown to have a significant impact on the quality of life and self-esteem of those affected. We interviewed six patients who were diagnosed with moderate-to-severe melasma with regard to the effect of their disorder on their self-esteem. All patients reported a significant negative effect on their quality of life and self-esteem. With successful therapy using a triple combination of cream and oral tranexamic acid to treat their melasma, all reported a marked improvement in self-esteem. Physicians who treat patients with melasma should be aware of its profound psychosocial effects and the improvement that successful melasma treatment can have on self-esteem.

Abstract
PURPOSE Pulmonary benign metastasizing leiomyoma (PBML), a rare condition of smooth muscle tumor, originates from women with a history of uterine leiomyoma (LM). Numerous genetic studies of uterine LM have been reported; however, there are few cytogenetic and molecular descriptions of PBML. Therefore, molecular subtyping is necessary to understand the pathogenesis of metastasizing sites. METHODS Driver gene exon-capture sequencing was performed on one patient's peripheral blood, paraffin samples from primary uterine LM, and lung metastasizing leiomyoma 8 years later. RESULTS The results showed that the same missense mutations of BLMH, LRP2, MED12, SMAD2, and UGT1A8 were concurrently mutated in the primary uterine LM and the PBML. Moreover, a splice mutation of PTEN (c.492+1G>A) was uniquely identified in the lung metastasis of the patient. CONCLUSION This study indicates that the metastatic lung lesions were derived from the same malignant cell clone of uterine LMs and later acquired the novel driver mutations in the evolution of the tumor. In addition, driver gene sequencing can discriminate somatic driver mutations as biological indicators of potential malignant leiomyoma and can identify pathogenic variation driver mutations, which could be used for individualized therapy.

Abstract
Abstract
Introduction.
Circulating tumor DNA analysis has the potential to transform the clinical management of patients with breast cancer. We assessed the accuracy of ultra-high sensitivity ctDNA testing in patients with advanced breast cancer.
Methods.
From a prospective tissue collection study, we identified 25 patients with a contemporaneous metastatic tissue biopsy and plasma for ctDNA testing. Tumour DNA from the metastatic tissue biopsy was sequenced with a validated clinical hybrid capture panel, while plasma cell free DNA was sequenced with AVENIO ctDNA technology – a molecular barcoded duplex sequencing based on CAPPseq technology. Sample collection is on-going and results from the full concordance series will be presented at the conference.
Results.
Circulating tumour DNA was detectable in 87% (20/23) of patients, with at least one variant from tissue sequencing identified in plasma. There was overall high agreement between tissue and plasma sequencing. The sensitivity of plasma testing for variants identified in tumour, positive percent agreement, was 75% (24/32). Plasma testing revealed a diversity of sub-clonal mutations including polyclonal ESR1, polyclonal FGFR2 and FGFR3 mutations, rare KRAS mutations, and TSC1 and MSH2 inactivating mutations.
Conclusions.
Circulating tumour DNA testing with molecular barcoded duplex sequencing offers high sensitivity for tumour variant detection. The extent of sub-clonal resistance mutations identified emphasises the genetic diversity of advanced breast cancer.

Abstract
Objective: To compare the diagnostic value of T2 weighted imaging (T2WI), diffusion-weighted imaging (DWI), and T2WI+ DWI magnetic resonance imaging (MRI) for staging of rectal cancers for improving the accuracy of tumor staging. Methods: From January 2011 to December 2013, 120 cases of rectal cancers proved by colonoscopy without receiving any anti-tumor treatment were enrolled retrospectively. The MRI data for these patients were divided into three groups, ie., T2WI, DWI and T2WI+ DWI, for evaluating the tumor stages. The results were compared with histopathologic findings. The sensitivity and specificity were calculated and compared with chi-square test. The nodal staging was predicted by using T2WI+ DWI. Results: The accuracy for prediction of tumor staging was 83.3%, 65.0% and 92.5% for T2WI, DWI, and T2WI+ DWI respectively. The specificity for evaluating T1 and T2 stage, and the sensitivity for evaluating T3 by DWI was significantly lower than those using T2WI and T2WI+ DWI in rectal cancers. The sensitivity for evaluation of T2 by DWI was lower than that using T2WI+ DWI (63.0% vs. 88.9%). The sensitivity for evaluation T2 and specificity for T3 by T2WI+ DWI was higher than thouse using T2WI only (88.9% vs. 51.9%, 94.0% vs. 72.0%). The accuracy for prediction of nodal staging by using T2WI+ DWI was 62.1% (72/116). Conclusions: T2WI is the key sequence for staging of rectal cancers. Although the diagnostic accuracy was not good by using DWI alone, the combination of T2WI and DWI can improve the accuracy significantly for tumor staging in rectal cancers, whereas the nodal staging was still a hard task for radiologists.

Citrus huanglongbing (HLB) or greening is a devastating disease of citrus worldwide and no effective control measure is currently available. Plant defense activators environmentally friendly compounds capable of inducing resistance against many plant pathogens. Earlier studies showed that foliar spray of plant defense inducers could slow down HLB disease progress. In this study, eight plant defense activators and three antibiotics were evaluated in three field trials for their effect to control HLB by trunk injection of young and mature sweet orange trees. Results showed that four trunk injections of several activators, including salicylic acid, oxalic acid, acibenzolar-S-methyl, and potassium phosphate, provided significant control of HLB by suppressing 'Candidatus Liberibacter asiaticus' titer and disease progress. Trunk injection of penicillin, streptomycin, and oxytetracycline hydrochloride resulted in excellent control of HLB. In general, antibiotics were more effective in reduction of 'Ca. L. asiaticus' titer and HLB symptom expressions than plant defense activators. These treatments also resulted in increased yield and better fruit quality. Injection of both salicylic acid and acibenzolar-S-methyl led to significant induction of pathogenesis-related (PR) genes PR-1 and PR-2 genes. Meanwhile, injection of either potassium phosphate or oxalic acid resulted in significant induction of PR-2 or PR-15 gene expression, respectively. These results suggested that HLB diseased trees remained inducible for systemic acquired resistance under field conditions. In summary, this study presents information regarding controlling HLB via trunk injection of plant defense activators and antibiotics, which helps citrus growers in decision making regarding developing an effective HLB management program.

Abstract
Fetal human liver cell fractions, which contain large numbers of hepatocyte progenitors, have high proliferation potential in vitro. To create an engineered liver tissue equivalent of a clinically significant size, however, repeated subcultivation and functional maturation are necessary in vitro. A commercially available human fetal liver cell fraction that was cultivated for some time in vitro has been reported to lose liver specific functions almost completely. We therefore investigated the effects of oncostatin M (OSM) and hepatocyte growth factor (HGF) in long-term three-dimensional (3D) culture using macroporous poly-L-lactic acid (PLLA) scaffolds on the restoration of such liver-specific functions of the fraction. 3D culture using PLLA scaffolds with OSM remarkably enhanced the albumin production and cytochrome P450 1A1/2 capacity with the culture time. HGF alone had no preferable effect on these functions even in 3D culture. Alpha-fetoprotein production was consistently suppressed in the 3D culture compared with that in monolayers. This suppression was not observed in the same types of culture of hepatocarcinoma Hep G2 cells. Despite these favorable observations on the 3D culture with OSM, the final attained functional levels at the 5th week were still over ten-times lower than those of Hep G2 cells when standardized with a cellular DNA amount. Although further improvement is needed for the complete functional restoration and maturation in vitro, these results demonstrate that a combination of 3D culture using PLLA scaffolds and OSM offers promising culture conditions for in vitro maturation of human hepatocyte progenitors.

Abstract
Objective: To evaluate the accommodative response of patients with intermittent exotropia (IXT) objectively, and study the changes of accommodative response of intermittent exotropia patients when maintaining binocular fusion. Methods: The prospective cohort study was used in this study. Twenty-four patients diagnosed with basic intermittent exotropia who visited the eye hospital of Wenzhou Medical University during October 2016 through January 2017 together with 24 normal volunteers were included, the 48 participants aged from 10 to 27 years old. The participants were divided into the case group and the control group. There were 11 males and 13 females in the case group, and 7 males and 17 females in the control group. The Open-filed autorefractor WAM-5500 (Grand Seiko, Japan) was used to measure the accommodative response of each eye under binocular and monocular viewing conditions at 5 m and 40 cm respectively. During the measurement, patients wore full correction spectacles to achieve distant best-corrected visual acuity of both eyes. The accommodative responses of each eye under binocular and monocular viewing conditions at distance or near between fellow eyes and groups were compared. Results: Under near fixation (40cm) binocular viewing conditions, the accommodative response of the fixating eye (-1.915±0.301)D was different from the deviating eye -1.649(-2.020, -0.304)D in the case group (Z=-3.714, P<0.001). Under near fixation monocular viewing conditions, the accommodative response of the fixating eye (-1.653±0.271)D was also different from the deviating eye -1.565 (-2.031, -0.667)D in the case group (Z=-2.971, P=0.003). During binocular viewing, the asymmetric value of the accommodative response between both eyes of the case group was 0.389(0.102, 1.458)D which was more significant than the normal controls' 0.155(0.009, 0.573)D (Z=-3.505, P<0.001), but during monocular viewing, there was no significant difference between the groups (Z=-1.908, P=0.056). Under near viewing conditions, the variation value of the fixating eyes of the case group was -0.228(-0.796, 0.382)D, which was greater than the variation value -0.086(-0.606, 0.628)D of the right eye of the normal controls, such difference is of statistical significance (Z=-2.279, P=0.023). Under distance viewing conditions, there was no significant difference in the accommodative response between fixating eyes and deviating eyes in case group neither during monocular viewing nor binocular viewing (t=-1.525, -1.729, P>0.05). Besides, the asymmetric values of accommodative response between groups were not significantly different (Z=-1.433, P=0.152. Z=-0.938, P=0.348). Under distance viewing conditions, the changes in accommodative response of each eye during both monocular viewing and binocular viewing were not significantly different between case group and normal controls (Z=-0.041, P=0.967. Z=-1.433, P=0.152). Conclusions: The accommodative responses of the fixating eye and deviating eye of patients with intermittent exotropia were asymmetric under near fixation binocular viewing conditions, and the accommodative response of the deviating eye tends to decrease. Besides, the change of accommodative response of the patients with intermittent exotropia when maintaining binocular fusion is more significant than that of the normal controls.

Abstract
This paper presents a method to evaluate radiation-tolerance without physical tests for a commercial off-the-shelf (COTS)-based monitoring device for high level radiation fields, such as those found in post-accident conditions in a nuclear power plant (NPP). This paper specifically describes the analysis of radiation environment in a severe accident, radiation damages in electronics, and the redundant solution used to prolong the life of the system, as well as the evaluation method for radiation protection and the analysis method of system reliability. As a case study, a wireless monitoring device with redundant and diversified channels is evaluated by using the developed method. The study results and system assessment data show that, under the given radiation condition, performance of the redundant device is more reliable and more robust than those non-redundant devices. The developed redundant wireless monitoring device is therefore able to apply in those conditions (up to 10 M Rad (Si)) during a severe accident in a NPP.

Abstract
In the presence of 5 mol% Pd(OAc)2, 1 equiv. of norbornene, and K2CO3, the reaction of 4-iodo-2-quinolones with tertiary o-bromobenzylic alcohols produced the desired benzopyran-fused 2-quinolones in moderate to high yields.
In the presence of 5 mol% Pd(OAc)2, 1 equiv. of norbornene, and K2CO3, the reaction of 4-iodo-2-quinolones with tertiary o-bromobenzylic alcohols produced the desired benzopyran-fused 2-quinolones in moderate to high yields. A Catellani-type mechanism involving vinylic C–H cleavage is proposed based on the results of control experiments and density functional theory calculations.

Abstract
BACKGROUND A new, recently issued national law and regulation in China conferred the responsibility of healthcare professionals in child maltreatment intervention. However, few studies have reported on the recognition and reporting of child maltreatment by healthcare professionals in China. The aim of this study was to assess healthcare professionals' knowledge, attitudes, and self-perceived behaviour in terms of identifying, assessing, and reporting child maltreatment cases in China. METHODS A cross-sectional survey of 877 healthcare professionals from four provinces was conducted using a structured questionnaire. RESULTS The respondents demonstrated insufficient knowledge on identifying potential child maltreatment cases. Over 30% of them were less than confident in the medical examination, evaluation, and treatment of child maltreatment cases, especially with regard to cases involving sexual abuse. Only 3.19% of respondents had ever received training on child maltreatment intervention, and as a result, lack of knowledge with regard to dealing with child maltreatment cases, referral procedures, and regulations was indicated to be the main cause of underreporting. CONCLUSIONS Healthcare professionals in China have insufficient knowledge, skills, and confidence when it comes to dealing with all aspects of child maltreatment. Although participants reported a positive attitude towards their role in detecting and reporting child maltreatment cases, there are obstacles that hinder them from doing so. Appropriate training courses should be developed to empower professionals with knowledge and skills, as well as increase their confidence in dealing with suspected child maltreatment cases.
