Abstract
OBJECTIVE The objective of this article is to investigate whether the aberrant expression of collagen triple helix repeat containing-1 (CTHRC1) from patients with systemic lupus erythematosus (SLE) could contribute to the pathogenesis of lupus. METHODS We divided SLE patients into active groups (Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score ≥ 6) and inactive groups (SLEDAI score < 6). Serum concentrations of CTHRC1, interferon alpha, interleukin (IL)-28A and IL-28B were determined using an enzyme-linked immunosorbent assay in a group of 40 patients with SLE. Results were compared with those from 23 healthy controls. RESULTS Serum CTHRC1 protein levels were higher in patients with SLE compared with healthy controls. Patients with active disease displayed higher CTHRC1 levels compared with those with inactive disease as well. There was a positive association between serum CTHRC1 levels and SLEDAI and erythrocyte sedimentation rate, and a negative correlation with complement 3 and 4. Moreover, serum CTHRC1 levels were higher in SLE patients with arthritis and anemia compared with patients without the above-mentioned manifestations. CONCLUSIONS These findings indicate CTHRC1 probably plays an important part in the pathogenesis of SLE, and is positively associated with disease activity, while it also likely refers to the development of arthritis and anemia in SLE. Therefore, CTHRC1 may provide a novel research target and shed new light on the pathogenesis and therapy of SLE.

Abstract
Bemisia tabaci (Gennadius) is an important agricultural pest with a worldwide distribution. Although B. tabaci is known to have a unique haplodiploid reproductive strategy, its sex determination mechanism is largely unknown. In this study, we cloned the full-length sequence of B. tabaci doublesex (Btdsx) and found that Btdsx has 28 splicing isoforms. We found two new splicing isoforms of transformer 2 (Bttra2), which encode two proteins. We also confirmed that both genes lack sex-specific splicing isoforms. Real-time quantitative PCR analysis showed that the expression of Btdsx and Bttra2 is higher in males than in females. RNA interference of Bttra2 affected the expression of Btdsx and vice versa. Furthermore, silencing of Bttra2 or Btdsx caused malformation of the male genitalia (anal style). It did not affect the female phenotype, but reduced the expression of vitellogenin gene in females. These results indicate that Btdsx is associated with sex determination in B. tabaci and that Btdsx and Bttra2 affect each other and are important for male genitalia formation. In addition to increasing our understanding of the roles of dsx and tra2 in the sex determination of B. tabaci, the results will be useful for studies of sex determination in other haplodiploid species.

Abstract
UNLABELLED Genetic risk of low bone mineral density in women remains unclear. This study found that a large percentage of Caucasian women have a high genetic risk of osteoporosis, and genetic risk scores are significantly associated with BMD variation in a bone healthy sample of Caucasian women. INTRODUCTION We aimed to examine the distribution of risk alleles in an independent sample and to determine if such genetic components are associated with bone mineral density (BMD) variation in the sample. METHODS Existing genotype data of 1205 women in the cross-sectional Genomic Wide Scans for Female Osteoporosis Gene Study (GWSFO) were analyzed. Multi-loci genetic risk scores (GRSs) based on 62 BMD-associated single nucleotide polymorphisms (SNPs) were calculated. Regression analysis was employed to assess the association between GRSs and BMD. To examine the effect of SNPs clustered within key pathways associated with the development of osteoporosis, subtype weighted GRS specific to WNT signaling (6 SNPs), RANK-RANKL-OPG (3 SNPs), and mesenchymal stem differentiation (3 SNPs) were generated for analysis. RESULTS The unweighted GRS ranged from 48 to 80. One third of the women carried 66% risk alleles. After adjusting for age, height, and body weight, each unit increase of weighted GRS was associated with a decrease in BMD of 0.097 at femur (p < 0.0001) and 0.110 (p < 0.0001) at lumbar spine. The weighted GRS accounted for only 3.17-4.52% of BMD variance. The WNT signaling pathway GRS (6 SNPs) and the RANK-RANKL-OPG signaling pathway GRS (3 SNPs) both were significantly associated with decreased BMD at femur neck (p = 0.0004 and p = 0.0063, respectively) and lumbar spine (p < 0.0001 and p = 0.0001, respectively), while the mesenchymal stem cell differentiation pathway (3 SNPs) GRSs were associated only with the lumbar spine BMD (p = 0.045). CONCLUSIONS A substantially large percentage of healthy Caucasian women have a high genetic risk of osteoporosis. Weighted GRS was significantly associated with decreased BMD. The contribution of subtype GRS to the BMD variation differs by specific biological pathway and skeletal regions.

Abstract
Victoria (Nymphaeaceae), an annual or perennial aquatic plant genus, contains only two species: V. amazonica (Poepp.) J. C. Sowerby and V. cruziana A. D. Orb. Both species have large floating leaves and variable flower colour. Both Victoria species are night bloomers, which have white petals on the first blooming night that then turn pink or ruby red on the second blooming day. The mechanism of the colour change of Victoria petals during anthesis is still unclear. In this study, flavonoids in Victoria petals of both species were evaluated and quantified by high-performance liquid chromatography with photodiode array detection (HPLC-DAD) and by ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) for the first time. In total, 14 flavonoids were detected in Victoria petals, including 4 anthocyanins and 10 flavonols. The flavonoid compositions differed across the two species, resulting in different colours between the inner and outer petals. With increased anthocyanin content across blooming days, the colour of Victoria flowers changed over time. The results of this study will improve understanding of the chemical mechanism of colour formation and lay the foundation for selective colour breeding in Victoria.

Abstract
UNLABELLED Inconsistent findings in regard to association between thiazide diuretic use and the risk of fracture have been reported during the past decade. This updated meta-analysis, which pooled data from 11 qualified prospective designed studies, found that thiazides have a significant protective effect on fracture risk. INTRODUCTION An updated comprehensive meta-analysis examine the association between thiazide diuretic use and therisk of fracture is needed. METHODS Cohort studies regarding thiazide diuretic exposure and the risk of fracture, published from inception to May 1 2017, were identified through MEDLINE, EMBASE, SCOPUS, and the Cochrane Database of Systematic Reviews. The literature search, study selection, study appraisal, and data extraction were pre-defined in the protocol and were independently conducted by two investigators. Due to the heterogeneity of the original studies, a random effects model was used to pool the confounder-adjusted relative risk (RR). RESULTS Eleven eligible cohort studies involving 2,193,160 participants were included for analysis. Overall, thiazide diuretic users, as compared with non-users, had a significant 14% reduction in the risk of all fractures (relative risk [RR], 0.86; 95% confidence interval [CI], 0.80-0.93; p = 0.009) and an 18% reduction in the risk of hip fracture (RR, 0.82; 95%CI, 0.80-0.93; p = 0.009). However, the effect size associated with thiazide use became slightly weaker when the analysis was limited to only high-quality original studies (quality score > 8) (RR, 0.89; 95%CI, 0.80-0.99; p = 0.005), studies with a larger sample size (> 10,000) (RR, 0.90; 95%CI, 0.80-1.00; p = 0.002), and studies published after 2007 (RR, 0.92; 95%CI, 0.82-1.02; p = 0.001). CONCLUSION Our findings indicate that thiazide diuretic use may convey a decreased risk of fracture and as such, the protective effect of this class of medicine should be considered when prescribing thiazide diuretics in clinical practice.

Abstract
OBJECTIVE To explore the therapeutic effect of Bifidobacterium combined with early enteral nutrition in severe acute pancreatitis. PATIENTS AND METHODS A total of 60 patients with severe acute pancreatitis admitted from November 2012 to November 2016 were retrospectively analyzed. According to the different treatment methods, the patients were divided into Bifidobacterium combined with early enteral nutrition group (experiment group) and early enteral nutrition group (control group). Serum ALB (albumin), CRP (C-reactive protein), WBC (white blood cell count) and PCT (procalcitonin) levels in both groups were observed. The pain relief time, diet recovery time, length of stay, and hospitalization costs between the two groups, were compared. The APACHE (acute physiology and chronic health evaluation scoring system) II score and SOFA (sequential organ failure assessment) score before and after nutritional support were compared between the two groups. Adverse events and complications were observed as well. RESULTS 58 patients recovered and 2 died after treatment. Improvements in laboratory indicators such as ALB, CRP, WBC and PCT were much better in the experiment group than the control group (p<0.05). Both the length of days and hospitalization cost were lower in the experiment group than those of the control group (p=0.0029, p=0.0435). In the comparison of hospitalization symptoms, shorter pain relief time and diet recovery time were found in the experiment group than those in the control group (p=0.0003, p=0.0218). After the treatment, APACHE II score and SOFA score of the experiment group were also higher than the control group. No significant differences in adverse events and complications between the two groups were exerted (p>0.05). CONCLUSIONS Bifidobacterium combined with early enteral nutrition can improve the nutritional status of patients with severe acute pancreatitis in the acute stage, which also enhances the patient's immune capacity and the body's resistance to disease.

Abstract
A fundamental challenge for surface acoustic wave (SAW) temperature sensors is the detection of small temperature changes on non-planar, often curved, surfaces. In this work, we present a new design methodology for SAW devices based on flexible substrate and bimorph material/structures, which can maximize the temperature coefficient of frequency (TCF). We performed finite element analysis simulations and obtained theoretical TCF values for SAW sensors made of ZnO thin films (~5 μm thick) coated aluminum (Al) foil and Al plate substrates with thicknesses varied from 1 to 1600 μm. Based on the simulation results, SAW devices with selected Al foil or plate thicknesses were fabricated. The experimentally measured TCF values were in excellent agreements with the simulation results. A normalized wavelength parameter (e.g., the ratio between wavelength and sample thickness, λ/h) was applied to successfully describe changes in the TCF values, and the TCF readings of the ZnO/Al SAW devices showed dramatic increases when the normalized wavelength λ/h was larger than 1. Using this design approach, we obtained the highest reported TCF value of −760 ppm/K for a SAW device made of ZnO thin film coated on Al foils (50 μm thick), thereby enabling low cost temperature sensor applications to be realized on flexible substrates.

Abstract
UNLABELLED This meta-analysis pooled results from 23 qualifying individual cohort studies and found that depression was significantly associated with an increased risk of fractures and bone loss. INTRODUCTION The association between depression and risk of fracture remains controversial. We conducted a comprehensive meta-analysis to examine the effect of depression on the risk of osteoporotic fractures and bone loss. METHODS We searched databases and reviewed citations in relevant articles for eligible cohort studies. Two investigators independently conducted study selection, appraisal, and data abstraction through the use of a standardized protocol. Random effect models were used for meta-analysis. Cochrane Q and I2 statistics were used to assess heterogeneity. Funnel plots and rank correlation tests were used to evaluate publication bias. RESULTS Twenty-three studies were included for meta-analysis. In studies that reported hazard ratio (HR) as the outcome (nine studies [n = 309,862]), depression was associated with 26% increase in fracture risk (HR = 1.26, 95% CI, 1.10-1.43, p < 0.001). Studies that reported risk ratio (RR) as the outcome (seven studies [n = 64,975]) suggested that depression was associated with 39% increase in fracture risk (RR = 1.39, 95% CI, 1.19-1.62, p < 0.001). Among studies that reported hip bone mineral density (BMD) as an outcome (eight studies [n = 15,442]), depression was associated with a reduced mean annual bone loss rate of 0.35% (0.18-0.53%, p < 0.001). The increased risk of fracture and bone loss associated with depression was consistent in all meta-analysis having modified inclusion criteria and in different subgroup analyses as well. Significant heterogeneity was observed in the meta-analysis; however, no significant publication bias was detected. CONCLUSION Depression is associated with a significant increased risk in fracture and bone loss. Effective prevention may decrease such risk.

Abstract
Objective:To observe the survival and migration ability of CXCR4-BMSCs in guinea pig cochlea with gentamycin induced sensorineural hearing loss, and to explore whether SDF-1/CXCR4 axis can mediate bone marrow mesenchymal stem cells (BMSCs) to cochlear homing.Method:BMSCs were isolated and extracted from guinea pigs. A bone marrow mesenchymal stem cell line with overexpression of CXCR4 was established. The animal model of sensorineural deafness was established by intraperitoneal injection of gentamicin[100 mg/(kg·d)]in 50 healthy guinea pigs. The successful deafness animals were randomly divided into three groups(14 rats in each group): sterilizing water group, BMSCs transplantation group and CXCR4-BMSCs transplantation group.Auditory brainstem response(ABR) were performed at 2 weeks and 4 weeks respectively after the tansplantation through cochlear tympanic pathway. The directional homing of the implanted cells in the cochlea was traced by the frozen section fluorescence of the cochlear tissue.Result:The hearing thresholds of the three groups were (91.3±5.2),(90.7±4.8)and (90.9±5.6)dB (SPL) respectively. There was no significant difference among them(P>0.05). In sterile Water group, the hearing thresholds were(89.7±6.4)dB and (89.2±6.7)dB respectively when detected on 2 and 4 weeks after transplantation. There were no significant difference(P>0.05);In BMSCs group, the hearing thresholds were (88.6±5.3)dB(SPL) on 2 weeks and (78.4±7.3)dB(SPL) on 4 weeks after transplantation. In CXCR4-BMSCs group, the hearing thresholds were(75.3±7.8)dB(SPL) on 2 weeks and (62.1±8.4)dB(SPL) on 4 weeks after transplantation. The differences were statistically significant (PThe hearing threshold was (75.3±7.8)dB (SPL) at 2 weeks after operation. The hearing enhancement was about 15 dB, the hearing threshold was (62.1±8.4)dB(SPL) at 4 weeks, the difference was statistically significant(P<0.05).Fluorescence tracing showed that the number of CXCR4-BMSCs homing cells was significantly increased, and showed a cohort like arrangement.Conclusion:The SDF-1/CXCR4 axis plays an important role in the directional homing and differentiation of the cells into the cochlea, which can improve the hearing repair ability of guinea pigs induced by gentamicin induced sensorineural deafness.

Abstract
Collagen VI-related myopathy, caused by pathogenic variants in the genes encoding collagen VI, represents a clinical continuum from Ullrich congenital muscular dystrophy (UCMD) to Bethlem myopathy (BM). Clinical data of 60 probands and their family members were collected and muscle biopsies of 26 patients were analyzed. COL6A1, COL6A2 and COL6A3 exons were analyzed by direct sequencing or next generation sequencing (NGS). Sixty patients were characterized by delayed motor milestones, muscle weakness, skin and joint changes with 40 UCMD and 20 BM. Muscle with biopsies revealed dystrophic changes and showed completely deficiency of collagen VI or sarcolemma specific collagen VI deficiency. We identified 62 different pathogenic variants in these 60 patients, with 34 were first reported while 28 were previously known; 72 allelic pathogenic variants in COL6A1 (25/72, 34.7%), COL6A2 (33/72, 45.8%) and COL6A3 (14/72, 19.4%). We also found somatic mosaic variant in the parent of 1 proband by personal genome machine amplicon deep sequencing for mosaicism. Here we provide clinical, histological and genetic evidence of collagen VI-related myopathy in 60 Chinese patients. NGS is a valuable approach for diagnosis and accurate diagnosis provides useful information for genetic counseling of related families.

Copper is the most essential trace element in the animal body. Nano-sized copper particles have been widely used in a number of different animal species in modern medicinal practice. The present study was designed to examine the effect of dietary copper sulfate/(CuSO4) and nano copper supplementation on serum antioxidant capacity of weaning piglets. A total of 28 Duroc piglets (21 days, and weighing ~7 kg) were randomly divided into three equal groups. The control group (n=4) was administered with a normal standard diet; however the CuSO4 (n=12) and nano copper (n=12) groups were treated with 50, 100 and 200 mg/kg/day body weight, respectively. After 28 days, blood serum copper-zinc superoxide dismutase (CuZn-SOD), ceruloplasmin (CP), malondialdehyde (MDA), myeloperoxidase (MPO), total antioxidant capacity (T-AOC), peroxidase (POD), nitric oxide (NO), nitric oxide synthase (NOS), hydrogen peroxide (H2O2) and inhibition of hydroxyl radical (CIHR) were analyzed from all groups. The results indicated that nano copper supplementation has significant (P less than 0.05) effect on the serum antioxidant capability as compared to dietary CuSO4 group in weaned piglets. Nano-size copper 100 mg/kg/day supplementation was confirmed to improve the immunity level by strengthening the antioxidant capacity of weaning piglets. Dietary supplementation with 100 mg/kg body weight nano copper could be a potential substitute for weaned piglets.

Abstract
Whether a prolonged interval between neoadjuvant chemoradiotherapy (nCRT) and esophagectomy could benefits conditions such as rectal cancer, still remains unknown. We therefore performed the current study to evaluate the influence of the interval between nCRT and esophagectomy on the clinical outcomes in patients with esophageal cancer. PubMed and Embase were searched to identify eligible cohort studies. The primary outcome was five-year overall survival (OS), and secondary outcomes included the incidence of anastomotic complications, perioperative mortality, pathologic complete response (pCR) rate, positive circumferential resection margin (CRM) rate, and R0 resection rate. A random-effects model was used for all meta-analyses irrespective of heterogeneity. Ten cohort studies with 2383 patients were included. Overall, the pooled estimate revealed that the prolonged interval has no impact on five-year OS (odds ratio (OR) 0.87, 95% CI 0.66 to 1.14, P = 0.30), with low heterogeneity (PH = 0.78, I2 = 0%). However, it was associated with an increased risk of anastomotic complication (OR 1.71, 95% CI 1.15 to 2.54, P = 0.008), with no effect on perioperative mortality (OR 1.20, 95% CI 0.79 to 1.83, P = 0.40). Additionally, the prolonged interval failed to increase the pCR rate (OR 1.02, 95% CI 0.78 to 1.33, P = 0.89). Even worse, it was correlated with a decreased R0 resection rate (OR 0.60, 95% CI 0.41 to 0.88, P = 0.009) and increased positive CRM rate (OR 2.20, 95% CI 1.44 to 3.36, P < 0.001). This study suggests that the prolonged interval between nCRT and esophagectomy fails to result in better outcomes, and in fact, could worsen clinical outcomes, with increasing anastomotic complications, and undermine resection completeness. However, this conclusion should be treated with caution because of the limitations of retrospective cohort study and substantial clinical heterogeneity. (The study was registered at PRESPERO as CRD42016048210).

Abstract
Objective: To observe the clinical efficacy and safety of coil embolization of septal branch in the treatment of obstructive hypertrophic cardiomyopathy (HOCM). Methods: Eighteen patients with HOCM hospitalized in our department from September 2014 to October 2016 were enrolled in this study. There were 12 males and 6 females in this cohort and the age of patients ranged from 22 to 64 years old. Left ventricular outflow tract gradient (LVOTG) was derived from echocardiographic apical five-chamber view at pre-operation and at 48 hours and 6 months post operation. 24-hour Holter ECG examination was performed to assess the ventricular tachycardia, atrial fibrillation, atrioventricular block at 3 days and 6 months after the interventional operation. Routine ECG and creatine kinase-MB (CK-MB) examination were performed at pre-operation, at 6, 24 and 48 hours post operation. Cardiac troponin T (cTnT) was detected at pre-operation, at 24, 48 hours and 6 days post operation. The clinical symptoms (including chest tightness, chest pain, shortness of breath, syncope) and NYHA classification were assessed at 1, 6 months after the operation by telephone follow-up or outpatient clinic visit. Results: The average preoperative LVOTG detected by cardiac catheter was 103.6 (92.0, 115.0) mmHg (1 mmHg=0.133 kPa) , and the average LVOTG significantly reduced to 44.3 (41.6, 47.2) mmHg immediately after operation (P<0.01). The average ventricular septal thickness at 48 hours (19.2±3.1) mm and 6 months (17.8±2.8) mm after operation tended to be lower than the preoperative ventricular septal thickness ((20.4±3.5) mm, P>0.05). The echocardiographic derived average LVOTG at 48 hours and 6 months after operation was 42.9 (41.1, 45.5) and 39.1 (37.5, 41.0) mmHg, which were significant lower than the preoperative average LVOTG (94.3 (88.5, 101.8) mmHg, both P<0.01). LVOTG at 6 months after operation was significantly lower than that at 48 hours after the operation (P<0.05). The NYHA classification at 6 months after operation was significantly improved compared to pre-operation NYHA classification (P<0.01). During and after the operation, there was no complete atrioventricular block and ventricular tachycardia, no patient developed anterior wall and inferior myocardial infarction. Only one patient experienced transient left bundle branch block. During the 6 months following-up, there was no death, syncope, chest pain, palpitations, shortness of breath, paroxysmal dyspnea and/or lower extremity edema, ventricular tachycardia, atrioventricular block and atrial fibrillation, complete atrioventricular block and ventricular arrhythmia. Conclusion: The coil embolization of septal branch is effective and safe for the treatment of patients with HOCM.

Abstract
Rhinitis during pregnancy refers to the various causes of rhinitis during the pregnancy, such as allergic rhinitis, vasomotor rhinitis, drug rhinitis, etc. Patients could have symptom before pregnancy, during pregnancy or postpartum symptoms. Pregnancy rhinitis (PR) appear only in pregnancy, and the main clinical manifestations is nasal congestion and the symptom disappeared after pregnancy. There are some similarities between PR and rhinitis during pregnancy, but the clinical feature, treatment option and prognosis are different. PR can affect the quality of life throughout pregnancy, and may even lead to increased risk of OSAHS in women and a threat to maternal and baby's safety. This article will review the research progress of the pregnancy rhinitis.

Abstract
AIM The cardioprotective effects of sevoflurane postconditioning (SpostC) are eliminated under diabetic conditions, and the underlying mechanism for this phenomenon remains unclear. Many studies have demonstrated that the hypoxia-inducible factor-1 (HIF-1) signalling pathway in the myocardium is impaired under diabetic conditions. This study was to investigate whether deferoxamine (DFO)-induced activation of HIF-1 signalling pathway can restore the cardioprotective effects of SpostC in diabetic rats. METHODS A model of myocardial ischaemia/reperfusion (I/R) injury was induced via ligation of the left anterior descending artery. SpostC was conducted by administering 1.0 MAC sevoflurane. After inducing the I/R injury, the following parameters were measured: myocardial infarct size, cardiac function, myocardial ultrastructure, mitochondrial respiratory function, respiratory chain enzyme activity, rate of reactive oxygen species (ROS) generation, and protein expression of HIF-1α, vascular endothelial growth factor (VEGF), cleaved caspase-3, Bcl-2 and Bax. RESULTS After DFO activated HIF-1 in the impaired myocardium of diabetic rats, SpostC significantly upregulated the protein expression of HIF-1α and its downstream mediator VEGF. This improved myocardial mitochondrial respiratory function and respiratory chain enzyme activity and reduced ROS generation as well as the protein expression of cleaved caspase-3 and Bax. As a result, myocardial infarct size decreased, and cardiac function and mitochondrial ultrastructure improved. CONCLUSION This study demonstrates for the first time that abolishment of the cardioprotective effects of SpostC in diabetic rats is associated with impairment of the HIF-1 signalling pathway and that DFO can activate HIF-1 to restore these cardioprotective effects of SpostC in diabetic rats.

Abstract
Objective: To evaluate the incidence of chronic thromboembolic pulmonary hypertension (CTEPH) secondary to acute pulmonary thromboembolism (PTE) and the serum level of growth differentiation factor-15(GDF-15). Methods: Ninety-six acute PTE patients were recruited in the study. Clinical data, Wells score, blood gas analysis, D-dimmer level, GDF-15 level, atrial and ventricular sizes, pulmonary arterial systolic pressure (PASP) and pulmonary artery CT (CTPA) data were collected. Patients were followed up to evaluate the cardiac function (WHO class), ultrasonic cardiogram and CTPA to confirm the incidence of CTEPH. Results: Eighty-fivepatients were followed for 5 months to 58 months (average 26.5±14.7 months). The incidence of CTEPH was 12.9% (11/85). Between CTEPH patients and non-CTEPH patients, PASP, right atrial and ventricular sizes, and GDF-15in the acute stage were significantly different(P<0.05). According to binary logistic regression analysis, the incidence of CTEPH was correlated positively with acute PASP and the serum level of GDF-15. Conclusions: The incidence of CTEPH in acute PTE patients was 12.9% in this study. Acute PASP and higher level of GDF-15 are predictive factors for CTEPH secondary to acute PTE.

Abstract
Objective: To evaluate the diagnostic performance of galactomannan(GM)detection in serum and BALF for invasive pulmonary aspergillosis (IPA) in non-neutropenic hosts. Methods: A pospective study was performed for 1 356 non-neutropenic hosts admitted to the Department of Pulmonary and Critical Care Medicine of the First Affiliated Hospital of Wenzhou Medical University from September 2014 to October 2015. Serum GM test was performed for all, and BALF GM test for a proportion of the patients. The patients were divided into an IPA group and a non-IPA group. SPSS 20.0 was adopted for statistical analysis. Results: A total of 1 361 cases were enrolled, aging 18-96 years, with an average age of (64±15) years. There were 879 male and 477 female patients. Thirty-nine cases were diagnosed as IPA, accounting for 2.9%. For serum GM test, the sensitivity, specificity, PPV and NPV were 43.6%(17/39), 94.1%(1 239/1 317), 17.9%(17/95)and 98.3%(1 239/1 261)respectively. Ninety-six cases received serum and BALF GM tests at the same time. If the cut-off value of BALF GM test was 0.8, the sensitivity, specificity, PPV and NPV were 86.7%(13/15), 60.5%(49/81), 28.9%(13/45), 96.1%(49/51)respectively, but if the value was 1.0, the sensitivity, specificity, PPV and NPV were 86.7%(13/15), 74.1%(60/81), 38.2%(13/34), 96.8%(60/62)respectively. The ROC curve area of BALF GM, serum GM and the combined serum and BALF GM was 0.87, 0.75 and 0.90, respectively. Conclusions: The sensitivity of serum GM test in non-neutropenic hosts was low, but it had a high negative predictive value.The best BALF GM cut-off value was 1.0. The combined serum and BALF GM tests improved the diagnostic performance.

Abstract
Chimeric antigen receptor (CAR) T-cell immunotherapies have shown unprecedented success in treating leukemia but limited clinical efficacy in solid tumors. Here, we generated 1928zT2 and m28zT2, targeting CD19 and mesothelin, respectively, by introducing the Toll/interleukin-1 receptor domain of Toll-like receptor 2 (TLR2) to 1928z and m28z. T cells expressing 1928zT2 or m28zT2 showed improved expansion, persistency and effector function against CD19+ leukemia or mesothelin+ solid tumors respectively in vitro and in vivo. In a patient with relapsed B-cell acute lymphoblastic leukemia, a single dose of 5 × 104/kg 1928zT2 T cells resulted in robust expansion and leukemia eradication and led to complete remission. Hence, our results demonstrate that TLR2 signaling can contribute to the efficacy of CAR T cells. Further clinical trials are warranted to establish the safety and efficacy of this approach.

Abstract
Hepatitis E virus (HEV) infection has been associated with a wide range of extrahepatic manifestations, so this study was designed to examine the effect and role of HEV on structural and molecular changes in the testicular tissues of Mongolian gerbils experimentally infected with swine HEV. HEV RNA was first detected in testis at 14 days post-inoculation and reached a peak between 28 and 42 days later with viral load between 3.12 and 6.23 logs/g by PCR assays. Changes including vacuolation, sloughing of germ cells, formation of multinuclear giant cells, degeneration, necrosis of tubules and damaged blood-testis barrier were observed through transmission electron microscopy. HEV ORF2 antigen was detected in the sperm cell cytoplasm along with decrease in relative protein of zonula occludens-1 through immunohistochemistry. HEV ORF3 antigen and ZO-1 protein were detectable by Western blotting. Lower (P<.05) serum testosterone and higher (P<.05) blood urea nitrogen level was observed in inoculated Mongolian gerbils. Likewise, increased (P<.05) germ cell apoptosis rate was detected with significant increased expression of Fas-L and Fas in HEV-inoculated groups at each time points. Up-regulation (P<.05 or P<.01) in mRNA level of Fas-L, Fas, Bax, Bcl-2 and caspase-3 was observed in HEV RNA-positive testes. Our study demonstrated that after experimental inoculation, HEV can be detected in testis tissues and viral proteins produce structural and molecular changes that in turn disrupt the blood-testis barrier and induce germ cell apoptosis.

Abstract
The Daya Bay experiment has observed correlations between reactor core fuel evolution and changes in the reactor antineutrino flux and energy spectrum. Four antineutrino detectors in two experimental halls were used to identify 2.2 million inverse beta decays (IBDs) over 1230 days spanning multiple fuel cycles for each of six 2.9 GW_{th} reactor cores at the Daya Bay and Ling Ao nuclear power plants. Using detector data spanning effective ^{239}Pu fission fractions F_{239} from 0.25 to 0.35, Daya Bay measures an average IBD yield σ[over ¯]_{f} of (5.90±0.13)×10^{-43} cm^{2}/fission and a fuel-dependent variation in the IBD yield, dσ_{f}/dF_{239}, of (-1.86±0.18)×10^{-43} cm^{2}/fission. This observation rejects the hypothesis of a constant antineutrino flux as a function of the ^{239}Pu fission fraction at 10 standard deviations. The variation in IBD yield is found to be energy dependent, rejecting the hypothesis of a constant antineutrino energy spectrum at 5.1 standard deviations. While measurements of the evolution in the IBD spectrum show general agreement with predictions from recent reactor models, the measured evolution in total IBD yield disagrees with recent predictions at 3.1σ. This discrepancy indicates that an overall deficit in the measured flux with respect to predictions does not result from equal fractional deficits from the primary fission isotopes ^{235}U, ^{239}Pu, ^{238}U, and ^{241}Pu. Based on measured IBD yield variations, yields of (6.17±0.17) and (4.27±0.26)×10^{-43} cm^{2}/fission have been determined for the two dominant fission parent isotopes ^{235}U and ^{239}Pu. A 7.8% discrepancy between the observed and predicted ^{235}U yields suggests that this isotope may be the primary contributor to the reactor antineutrino anomaly.

Abstract
Objective: To observe the influence on spectacle independence, satisfaction and visual function after cataract surgery monovision with different ADD. Methods: Prospective clinical study. All patients were collected from the department of ophthalmology, Shanghai JiaoTong University Affiliated Sixth People's Hospital who were diagnosed as bilateral cataract from Oct. 2013 to Mar. 2015. This study comprised 64 cases (128 eyes). All consecutive patients scheduled to undergo bilateral cataract phacoemulsification and implantation of a monofocal AcrySof IQ IOL. The average age of patients was (65.4± 6.0) years old, ranged from 51 to 70 years. 28 males and 36 females. According to the different demands of spectacle independence and living habits of patients, all cases were divided into two groups: MV1 group (32 patients), whose near addition being 1.25-1.75 D and MV2 group (32 patients), whose near addition being 2.25-2.75 D. Parameters 6 months postoperatively included binocular uncorrected distance, intermediate, and near visual acuities, stereo vision and refractive states were analyzed. Parameters of spectacle independence, subjective visual symptoms and patient satisfaction according to visual function questionnaire were analyzed at the same time. T test was used to compare uncorrected visual acuity. Whitney U test was operated in stereo vision comparison. Chi-square test was applied in sex-distribution comparison and visual function questionnaire between two groups. Results: The uncorrected distance vision in MV1 group was (0.09±0.09), while it was (0.11±0.08) in MV2 group. The uncorrected intermediate vision in MV1 group was (0.27±0.25), and it was (0.30±0.22) in MV2 group. There were no significant difference between two groups in bilateral uncorrected distance vision (t=1.62, P=0.264, LogMAR), intermediate (t=- 0.23, P=0.876, LogMAR). However, there was significant difference between two groups in uncorrected near vision (t=2.38, P=0.021, LogMAR). It was (0.06±0.06) in MV1 group and (0.02±0.07) in MV2 group. Moreover, near stereo vision was better in MV1 group than MV2 group (Z=- 1.29, P=0.031). On the questionnaire, all patients in two groups had no significant difference in their daily lives discomfort (χ(2)=0.10, P=0.756). In MV2 group, there were 2 patients complained obstacles while walking stairs dimly. In MV1 group, there were 3 patients had to wear low degrees of presbyopic glasses when they were on near work. Percentage of patients spectacle independence was less than 90% in MV1 groups. In MV2 group, one case needed low degrees of myopic glasses when he was on intermediate computer work and playing table games. Conclusion: Different near addition has similar advantages to different patients on spectacle independence, satisfaction and visual function after cataract surgery.

Abstract
OBJECTIVE We screened and identified the differential expression of the methylation phenotype in the whole genome of colorectal laterally spreading tumor (LSTs). MATERIALS AND METHODS 3 tissue samples of colorectal polypoid adenomas (PAs), 3 tissue samples of LSTs and 3 tissue samples of colon cancer were analyzed with a high-density gene chip, and about 450,000 methylation sites were detected covering approximately 95% of the CpG islands. The Delta Data screening was taken through a cluster analysis of methylation phenotype differential expression. 50 tissue samples each of PAs patients, LSTs patients, and colorectal cancer patients were selected. Methylation-specific PCR (MSP) was used to detect RASSF1A and WIF-1 methylation levels. He RT-PCR method was used to detect the relative mRNA expression levels for methylation expression identification. RESULTS The degree of LST methylation was higher than that of PAs, and 1234 genes were found to have a lower expression when compared to colorectal cancer samples. 764 genes had a higher expression when compared to colorectal cancer, and 559 genes lower expression when compared to PAs. The average methylation level of LSTs was higher than that of PAs, and lower than that of colorectal cancer. The chromosomal location was taken on these 1234 genes, which were higher than that of PAs, and lower than that of colorectal cancer; 518 genes were located on chromosome No. 2 (41.98%), 236 on No. 5 (19.12%), 357 on No. 8 (28.93%), and 123 on No. 10 (9.97%). According to clustering analysis, DNA differentially methylated sites were mainly on genes of cell adhesion molecules regulation, signaling pathways, energy transduction, cell cycle and apoptosis. The positive rate of RASSF1A and WIF-1 methylation in the tissues of LSTs patients were higher than that of PAs, and lower than that of colorectal cancer; differences were statistically significant (p<0.05). The relative expression levels of RASSF1A and WIF-1mRNA in the tissues of LSTs patients were lower than that of PAs, higher than that of colorectal cancer, and the difference was statistically significant (p<0.05). CONCLUSIONS The administration of high-density gene chip technology has a good application value to screen the differential expression of LSTs gene methylation phenotype. Results are consistent with the identification results.

Abstract
This study aimed to test the diagnostic performance of a fully quantitative fibrosis assessment tool for liver fibrosis in patients with chronic hepatitis B (CHB), primary biliary cirrhosis (PBC) and non-alcoholic steatohepatitis (NASH). A total of 117 patients with liver fibrosis were included in this study, including 50 patients with CHB, 49 patients with PBC and 18 patients with NASH. All patients underwent liver biopsy (LB). Fibrosis stages were assessed by two experienced pathologists. Histopathological images of LB slices were processed by second harmonic generation (SHG)/two-photon excited fluorescence (TPEF) microscopy without staining, a system called qFibrosis (quantitative fibrosis) system. Altogether 101 quantitative features of the SHG/TPEF images were acquired. The parameters of aggregated collagen in portal, septal and fibrillar areas increased significantly with stages of liver fibrosis in PBC and CHB (P<0.05), but the same was not found for parameters of distributed collagen (P>0.05). There was a significant correlation between parameters of aggregated collagen in portal, septal and fibrillar areas and stages of liver fibrosis from CHB and PBC (P<0.05), but no correlation was found between the distributed collagen parameters and the stages of liver fibrosis from those patients (P>0.05). There was no significant correlation between NASH parameters and stages of fibrosis (P>0.05). For CHB and PBC patients, the highest correlation was between septal parameters and fibrosis stages, the second highest was between portal parameters and fibrosis stages and the lowest correlation was between fibrillar parameters and fibrosis stages. The correlation between the septal parameters of the PBC and stages is significantly higher than the parameters of the other two areas (P<0.05). The qFibrosis candidate parameters based on CHB were also applicable for quantitative analysis of liver fibrosis in PBC patients. Different parameters should be selected for liver fibrosis assessment in different stages of PBC compared with CHB.

Abstract
The prevention of chemotherapy‐induced nausea and vomiting was one of the most challenging supportive care issues in oncology, especially to highly emetogenic chemotherapy (HEC). A total of 645 patients were randomized into fosaprepitant group (fosaprepitant/placebo 150 mg d1 in combination with granisetron and dexamethasone) or aprepitant group (aprepitant/placebo 125 mg d1; 80 mg d2‐d3 plus granisetron and dexamethasone).The primary endpoint was the percentage of patients who had a complete response (CR) over the entire treatment course (0–120 hr, overall phase [OP]). It was assessed by using a non‐inferiority model, with a non‐inferiority margin of 10%. The difference of the CR rate was compared between two groups with chi‐square analysis. Six hundred and twenty‐six patients were included in the per protocol analysis. The percentage of patients with a CR in the fosaprepitant group was not inferior to that in the aprepitant group (90.85% versus 94.17%, p = .1302) during OP. Whether the cisplatin‐based chemotherapy or not, the CR rate of the fosaprepitant group was not inferior to that of the aprepitant group. Both regimens were well tolerated. The most common adverse event was constipation. Fosaprepitant provided effective and well‐tolerated control of nausea and vomiting associated with HEC in Chinese patients.

Abstract
Porcine deltacoronavirus (PDCoV) is a newly discovered coronavirus that causes diarrhoea, vomiting and dehydration in sucking and nursing piglets. It was first reported in Hong Kong in 2012 and has since been discovered in the United States, Canada, South Korea, mainland China, Thailand and Laos. PDCoV has been experimentally proved to lead to diarrhoea in swine and it was detected positive in pigs in Guangdong, southern China. In our study, 252 faecal and intestinal samples from sucking piglets and sows with diarrhoea were surveyed for common enteric viruses. We found a prevalence of PDCoV (21.8%), porcine epidemic diarrhoea virus (65.5%), transmissible gastroenteritis virus (0%), rotavirus group A (25.0%) and porcine kobuvirus (68.7%). We isolated 13 PDCoV strains and discovered that PDCoV infections were often co‐infections with kobuvirus rather than the commonly linked porcine epidemic diarrhoea virus. Phylogenetic analysis of S gene and N gene revealed that 11 of 13 PDCoV strains belonged to Chinese lineage. As for the left two strains, one single strain (CHN‐GD16‐05) belonged to American and Korean lineages while another strain (CHN‐GD16‐03) was similar to a Thai strain, but only in the S gene. This suggested a possible recombination event between the Thai and the newly described Chinese strain.

Abstract
AIM To explore the metabolic characteristic of autochthonous Saccharomyces cerevisiae strains in Chinese light-fragrant liquor fermentation. METHODS AND RESULTS Inter-delta amplification analysis was used to differentiate the S. cerevisiae strains at strain level. Twelve biotypes (I-XII) were identified among the 72 S. cerevisiae strains preselected. A comparison was conducted between solid-state fermentation (SSF) and submerged fermentation (SmF) with S. cerevisiae strains had different genotype, with a focus on the production of ethanol and the volatile compounds. The degree of ethanol ranged from 28·0 to 45·2 g l-1 in SmF and from 14·8 to 25·6 g kg-1 in SSF, and SSF was found to be more suitable for the production of ethanol with higher yield coefficient of all the S. cerevisiae strains. The metabolite profiles of each yeast strain showed obvious distinction in the two fermentations. The highest amounts of ethyl acetate in SmF and SSF were found in genotype VII (328·2 μg l-1 ) and genotype V (672 μg kg-1 ), respectively. In addition, the generation of some volatile compounds could be strictly related to the strain used. Compound β-damascenone was only detected in genotypes I, II, X and XII in the two fermentation processes. Furthermore, laboratory scale fermentations were clearly divided into SSF and SmF in hierarchical cluster analysis regardless of the inoculated yeast strains, indicating that the mode of fermentation was more important than the yeast strains inoculated. CONCLUSION The autochthonous S. cerevisiae strains in Chinese light-fragrant liquor vary considerably in terms of their volatiles profiles during SSF and SmF. SIGNIFICANCE AND IMPACT OF THE STUDY This work facilitates a better understanding of the fermentative mechanism in the SSF process for light-fragrant liquor production.

Abstract
Abstract
BACKGROUND: The addition of taxanes to anthracycline-based adjuvant chemotherapy has improved disease free survival (DFS) in women with high-risk early-stage breast cancer. Many studies have sought to optimize the dose intensity and density of these agents to produce improvements in outcome and tolerability. The purpose of this study was to assess the use of metronomic doxorubicin plus daily oral cyclophosphamide (AC) for 12 weeks followed by nab-paclitaxel (nP) for 12 weeks in this population. Those patients with Her2 positive disease were also given adjuvant trastuzumab.
METHODS: A non-randomized phase II clinical trial was designed to (1) test the DFS at 2 years compared to historical controls, (2) assess dose intensity delivered, (3) assess use of nP in the adjuvant setting, and (4) evaluate toxicities associated with the regimen. Overall survival (OS) was a secondary outcome. The dosing of A was 24mg/m2 IV qweek and C was 60mg/m2 oral daily; nP, 100mg/m2 IV qweek.
RESULTS: Sixty patients were enrolled on the study with a median follow-up of 6 years and a median age of 50 (range 30-69). 58% of patients had node positive disease. Receptor categories included hormone receptor positive (ER positive or PR positive) and HER2 negative (n=24; 40%); ER negative, PR negative, and HER2 negative (triple negative; n=19; 32%); or HER2 positive (n=17; 28%). DFS at 2 years was 93% (1 death, 3 recurrence) and at 6 years was 82%, comparable to historical controls. OS at 2 years and 6 years was 98% and 88%, respectively. Mean dose intensity was greater than 90% for AC and 88% for nP. Treatment was well-tolerated with the most common grade ≥3 toxicity being neutropenia and a 2% incidence of febrile neutropenia.

CONCLUSSIONS: Patients achieved similar DFS to that seen in historical controls with similar rates of adverse events. Since nP dosing was 100 mg/m2, even with 88% dose intensity, the delivered taxane dose is greater than standard weekly paclitaxel. Notably disease control was particularly impressive in the triple negative subtype, which has been shown to benefit from nP over standard paclitaxel in the neoadjuvant setting in the GeparSepto (GBG 69) trial. Metronomic AC followed by nP is a safe, effective option for delivery of adjuvant chemotherapy for high-risk patients.

Abstract
Objective: To identify the source and to comment on control program regarding an outbreak of paratyphoid A fever in a county, through field studies. Methods: Descriptive epidemiological methods were adopted to describe the epidemiological characteristics of the outbreak, which occurred in Yuanjiang county, Yunan province between 2010-2011, China. Case-control study with environmental investigation was performed to identify related risk factors and pathogens while isolation and susceptibility on the suspected pathogens were conducted. Subsequently, intervention and preventive measures were taken for the control of the outbreak. Results: A total of 600 cases were diagnosed and reported as paratyphoid fever A which spread over the whole Yuanjiang county, including 10 townships with different incidence rates. The disease was spatially clustered and the prevalence rates in these townships decreased with increasing distances from the polluted fields. Data from the case-control study discovered that consumption of raw vegetables was the main risk factor associated with this outbreak of paratyphoid fever (OR=65.3, P<0.001). Management of patients did not meet the requirements while feces and urine of the outpatients polluted the wastewater system in the city. Salmonella paratyphi A isolates were identified from the improperly disinfected wastewaters in hospitals and city systems, respectively. After the measures as prohibiting the planting of vegetables in contaminated fields and disinfection of hospital wastewater were taken, the outbreak subsided. Conclusions: Urban and hospital wastewater used for vegetables irrigation together with the tradition of eating uncooked vegetables seemed responsible for the outbreak of this paratyphoid fever. Intervention programs carried by the local government played a key role in controlling this large outbreak.
