Abstract
OBJECTIVE To explore the spatio-temporal characteristics of Oncomelania hupensis snails along the Danyang section of the Beijing-Hangzhou Grand Canal and the Danyang-Jintan-Liyang Canal, so as to provide scientific evidence for the dynamic assessment of the risk of snail spread in this region. METHODS O. hupensis snail status was collected in the plain regions with waterway networks in the study area from 2012 to 2017. The spatio-temporal variations of snail distribution were investigated along the Danyang section of the Beijing-Hangzhou Grand Canal and the Danyang-Jintan-Liyang Canal using buffer zone analysis, spatial autocorrelation, hotspot analysis and standard deviational ellipse with the geographical information system (GIS) tools. RESULTS The number of snail habitats showed a tendency towards a rise in the study area from 2012 to 2017, and snail habitats were predominantly distributed in the 1 000 m long buffer zone of the Danyang-Jintan-Liyang Canal, notably along the Jiuqu River at the junction between the Beijing-Hangzhou Grand Canal and the Danyang-Jintan-Liyang Canal. The distribution of snail habitats appeared spatial autocorrelations in 2014, 2016 and 2017, and the hotspot areas were mainly identified at the junction between the Danyang-Jintan-Liyang Canal and the Beijing-Hangzhou Grand Canal. In addition, the overall distribution of snail habitats was located in the northeastern-southwestern part of the study aera, and gradually shifted to the southern and northern parts with the time. CONCLUSIONS The spatial distribution of O. hupensis snails is complex along the Danyang section of the Beijing-Hangzhou Grand Canal and the Danyang-Jintan-Liyang Canal, and there is a risk of snail spread from the upper reaches to the lower reaches, where snail control needs to be intensified.

Abstract
Schistosomiasis was once heavily endemic in Jiangsu Province. Following the control efforts for several decades, schistosomiasis was almost eradicated in all endemic counties in Jiangsu Province in 1980, and transmission control was achieved in the province in 2011. According to the principle of "implementing the control measures with adaptation to local circumstances and guiding the control programs with classified interventions", an integrated strategy with emphasis on the management of both infectious sources and snails has been recently employed for schitsosomiasis control in Jiangsu Province. In addition, a sensitive and highly effective surveillance system has been built and the application of novel techniques and information construction has been intensified to effectively interrupt the transmission of schistosomiasis in the Province. Transmission interruption of schistosomiasis was achieved in all endemic counties in Jiangsu Province. The paper summarizes the endemic situation of schistosomiasis, progress of schistosomiasis control, and major schistosomiasis control measures implemented during the stage of transmission interruption in Jiangsu Province.

Abstract
OBJECTIVE To understand the status of grass-roots schistosomiasis control professionals in Jiangsu Province, so as to provide scientific evidence for the rational resource allocation and the improvement of capability building. METHODS A cross-sectional survey was conducted by telephone interview and e-mail among city- and county-level disease prevention and control institutions that undertook schistosomiasis control activities in Jiangsu Province, and the age, educational background, major, duration of working, professional title and professional capability were descriptively analyzed. RESULTS There were totally 274 fulltime schistosomiasis control professionals working at grass-roots institutions in Jiangsu Province, with a mean age of (43.19 ± 9.47) years. The least professionals were below 30 years of age (12.77%, 35/274), and the most professionals were aged from 41 to 50 years (36.86%, 101/274). Among the 274 professionals, 43.07% (118/274) had duration of working of less than 10 years, 62.04% (170/274) had a bachelor degree, and 40.88% (112/274) had the medium-level professional title. CONCLUSIONS A schistosomiasis control team with a relatively high academic degree and professional title has been built at the grassroot level in Jiangsu Province. However, capability building remains to be improved through the participation of more young professionals and professional training with adaptation to local conditions.

Abstract
OBJECTIVE TF-box and WD repeat domain-containing 7 (FBW7), a component of SCF ubiquitin ligase complex, usually acts as a tumor suppressor because it has an ability in the inhibition of cell proliferation. Nevertheless, the role of FBW7 in intervertebral disc degeneration (IDD) is not quite understood. MATERIALS AND METHODS The total protein and RNA were isolated from patients' disc tissues. WB was carried out to analyze the collagen II and FBW7 protein levels of different Pfirrmann grades disc degeneration. Reverse transcription-polymerase chain reaction (RT-PCR) was used to test the collagen II and FBW7 mRNA expression in these disc samples. NP cells were transfected with siRNA-FWB7 to downregulate the FBW7 expression. SiRNA-NC was used as the sham group. Cyclin E, E2F1, and E2F2 were analyzed with WB and RT-PCR. RESULTS In this study, different kinds of degenerated disc tissues were analyzed, and it was found that FBW7 was overexpressed in much severe degeneration condition, which was also proved by the IL-1β stimuli nucleus pulposus (NP) cells degeneration model in vitro. Interestingly, the results showed that FBW7 suppression could reverse the degeneration of NP cells. Furthermore, we found that FBW7 induced NP cell cycle arrest in the G1 phase of and inhibited cell proliferation by upregulating p27 expression in vitro. The overexpression of p27 resulted in the inhibition of cyclin E, which promotes cell proliferation. CONCLUSIONS Taken together, our study uncovered that FBW7 played an essential inhibitory role in NP cells proliferation, providing new insights that FBW7 may be a potential strategy for IDD treatments.

Abstract
BACKGROUND The objective of this study was to detect the expression and distribution characteristics of five proteins (the hypoxia-inducible factor 1alpha [HIF-1a], HIF-2a, vascular endothelial growth factor [VEGF], VEGF-2 receptor [VEGFR-2] and hypoxia-induced mitogenic factor [HIMF]) in kidney of Tibetan sheep, plain sheep and goat. The results will provide the basic information for the comparative study of sheep breeds living at different altitudes. MATERIALS AND METHODS The kidney tissues were collected from healthy adult Tibetan sheep, plain sheep and goats and made into paraffin sections. Histological characteristics were assessed by haematoxylin and eosin staining. Expressions of HIF-1a, HIF-2a, VEGF, VEGFR-2 and HIMF proteins were measured by immunohistochemical staining. RESULTS Immunohistochemistry results showed that the positive expression signals of HIF-1a, HIF-2a, VEGF and VEGFR-2 were detected in epithelial cells of renal tubules and collecting tubules, renal corpuscles in the kidneys of the three sheep breeds. Positive expression signals of HIMF were detected in epithelial cells of proximal tubules and distal tubules in Tibetan sheep and epithelial cells of distal tubules in goat. Immunostaining intensity of HIF-1a, HIF-2a, VEGF and VEGFR-2 proteins in Tibetan sheep was significantly higher than that in both plain sheep and goat (p < 0.05). Immunostaining intensity of HIMF in Tibetan sheep was higher than goat (p < 0.05). Positive expression signals of HIMF were not detected in plain sheep. CONCLUSIONS The expression and distribution characteristics of HIF-1a, HIF-2a, VEGF, VEGFR-2 and HIMF in the studied kidney tissues suggested that these proteins may be related to the physiological regulation of Tibetan sheep kidney in hypoxia environment, and therefore might be important regulating proteins for Tibetan sheep to adapt to high altitude hypoxia environment.

Abstract
OBJECTIVE To evaluate the value of a dynamic automatic identification system in routine miracidium hatching test with nylon gauzes. METHODS Different quantities of fresh Schistosoma japonicum eggs were added to bovine fecal samples and divided into the low-infection group, medium-infection group and high-infection group, while the bovine feces without S. japonicum eggs served as negative controls. The detection efficiency and accuracy were compared between the identification system and manual detection in different groups. RESULTS The identification system can automatically identify S. japonicum miracidium. The detection rate and efficiency of S. japonicum miracidium in bovine fecal samples were both higher by using the identification system than by manual detection. Notably in the low-infection group, the identification system had a significantly higher rate of detection of S. japonicum miracidium than manual detection (χ2 = 10.769, P = 0.002). The identification system completed the detection of bovine fecal samples in the field within 1 min. CONCLUSIONS The dynamic automatic identification system may effectively improve the detection efficiency and accuracy of routine miracidium hatching test with nylon gauzes, and it may replace manual detection to be used in the field schisotsomiasis examinations and related researches.

Abstract
OBJECTIVE To analyze and investigate the changing trend of the endemic situation of schistosomiasis in national surveillance sites of Jiangsu Province from 2011 to 2018, so as to provide scientific evidence for formulating strategies for schistosomiasis control. METHODS From 2011 to 2014, the national schistosomiasis surveillance sites were set in seven schistosomiasis endemic counties (cities, districts) across Jiangsu Province as according to the National Schistosomiasis Surveillance Scheme (2011 version), and from 2015 to 2018, the national surveillance sites were assigned in all 64 counties (cities, districts) endemic for schistosomiasis in Jiangsu Province according to the National Schistosomiasis Surveillance Scheme (2014 version). Schistosoma japonicum infections in local populations, mobile populations and livestock, and snail status were monitored in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and the monitoring data were statistically analyzed. RESULTS The sero-prevalence of S. japonicum infections was 1.50% to 4.61% among local populations in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and a higher sero-prevalence was seen in men than in women, with the sero-positives predominantly detected in local populations at ages of over 50 years. The positive rate of stool examinations was 0 to 0.14% among sero-positive local populations in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and no acute case was found in local populations during the study period. The sero-prevalence of S. japonicum infections was 0.46% to 15.97% among mobile populations in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and no egg-positives were identified. A total of 1 453 livestock were tested in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and no S. japonicum infections were detected. During the period from 2011 through 2018, snail survey was conducted in an area of 216 million m2 in the national schistosomiasis surveillance sites of Jiangsu Province, and 1 291.01 hm2 snail habitats were identified, with snail densities ranging from 0.01 to 0.47 snails/0.1 m2; however, no S. japonicum infections were identified in snails. CONCLUSIONS The overall endemic situation of schistosomiasis appears a tendency towards a decline in Jiangsu Province, and S. japonicum infection remains at a low level in both humans and livestock. No S. japonicum infection has been identified in local populations in Jiangsu Province since 2012. In the future, monitoring and management of imported sources of S. japonicum infections should be intensified in Jiangsu Province, and the capability building of passive surveillance of schistosomiasis should be improved in sentinel hospitals in national schistosomiasis surveillance sites of Jiangsu Province. In addition, the examination of schistosomiasis should be strengthened in mobile populations in Jiangsu Province, a sensitive and effective surveillance-response system for schistosomiasis is urgently needed.

Abstract
OBJECTIVE To investigate the spatio-temporal characteristics of Oncomelania hupensis snails along the Jiangsu section of the Yangtze River, so as to provide evidence for eliminating schistosomiasis and formulating precision control measures in Jiangsu Province. METHODS A total of 75 marshlands were randomly sampled from Nanjing, Zhenjiang and Yangzhou cities along the Jiangsu section of the Yangtze River basin, and the spatio-temporal distribution and changing patterns of O. hupensis snails were investigated using the spatial autocorrelation analysis, kernel density analysis and hotspot analysis during the period from 2015 through 2017. RESULTS There was a spatial autocorrelation in the mean snail density along the Jiangsu section of the Yangtze River basin during the period from 2015 through 2017. The number of living snails and the density of living snails showed an overall decline in Yangzhou City; however, both showed a slight increase in 2016. Kernel density analysis and hotspot analysis showed that the hotspots of living snails were located in the regions neighboring the marshlands at the Yangzhou-Zhenjiang boundary areas along the Jiangsu section of the Yangtze River basin. CONCLUSIONS There is a spatial autocorrelation in the snail distribution with hotspots along the Jiangsu section of the Yangtze River basin, and the surveillance of snails should not be neglected in the marshlands in Jiangsu Province.

Abstract
OBJECTIVE To assess the total factor productivity (TFP) of schistosomiasis control programs in Jiangsu Province, so as to provide insights into sustainable schistosomiasis control. METHODS The data envelopment analysis-Malmquist index method was employed to analyze the human resources and financial investments in schistosomiasis control programs from health sectors in each schistosomiasis-endemic city of Jiangsu Province from 2005 to 2015, and assess the outputs of each schistosomiasis control project. RESULTS The overall productive efficiency of schistosomiasis control programs in Jiangsu Province showed an increasing tendency, and the mean fluctuation of annual TFP was 2.3%. The comprehensive technical efficiency, including pure efficiency and scale efficiency, appeared a steady increase with minor fluctuations, and the mean fluctuation of annual comprehensive technical efficiency was 3.8%. The growth rate of technical progress fluctuated greatly from 2005 to 2011, and showed a steady increase from 2012 to 2015, which became a major contributor to the growth of TFP. A higher growth rate of TFP was seen in Huai ' an and Changzhou cities, which showed a greater comprehensive technical efficiency, and a large fluctuation was observed in the growth rate of technical progress in Yancheng, Nanjing, Huai ' an and Yangzhou cities. CONCLUSIONS There is a continuous improvement in the technical level of schistosomiasis control programs in Jiangsu Province, and technical application and supervision and management capacity also show a steady increase. In addition, the application of new techniques and new strategies contributes greatly to TFP growth. In the future, the investment into new techniques and new strategies should be increased to ensure the sustainable schistosomiasis control in Jiangsu Province.

Abstract
Abstract
Background
Cardiac fibrosis (CF) plays a critical role in the pathogenesis of heart failure (HF), predisposing to contractile dysfunction, myocardial stiffness and life-threatening arrhythmias. Early detection and intervention of myocardial fibrosis, therefore, can delay or prevent the progression of HF. Current diagnostic and treatment options for CF, however, are very limited.
Purpose
To test the hypothesis that circulating lncRNA expression signature can be a sensitive biomarker to diagnose and correlate with the extent of CF in human heart.
Methods
Plasma RNA samples from healthy control (n=23) and from patients with diffuse myocardial fibrosis documented by cardiac magnetic resonance (T1 mapping technique, n=16) were analyzed by RNA sequencing (RNASeq), followed by differential expression, gene ontology/pathway and receiver operating characteristic (ROC) curve analyses.
Results
RNASeq revealed that 439 mRNAs were differentially expressed in the plasma from patients with CF, compared to that from controls. Gene ontology analyses showed significant enrichment of these CF-linked genes in cytoskeleton organization, innate immune response, and MAPK-Erk signaling, cellular processes known to contribute to the development of CF. Further analyses showed that 84 plasma lncRNAs were dysregulated in patients with CF; 5 of the lncRNAs (ENSGehz746.10420265401.1, ENSGehz746.10420229124.6, ENSGehz746.10420281376.1, ENSGehz746.10420273275.1 and ENSGehz746.10420179818.13) showed concordant changes with their cis-mRNA (UBB, VIM, BCL2L1, PPP3R1 and PCBP1). Hierarchical clustering analyses demonstrated that the expression signature of plasma lncRNAs could distinguish patients with CF from control patients (classification accuracy 87%). The expression levels of plasma lncRNAs ENSGehz746.10420258017.1 and ENSGehz746.10420265401.1, in particular, were markedly downregulated in patients with myocardial fibrosis. ROC curve analyses showed that low expression levels of ENSGehz746.10420258017.1 and ENSGehz746.10420265401.1 were highly sensitive and specific to detect the presence of CF in human heart (AUC 0.9 for both lncRNAs, Figure).
LncRNA Predicts Cardiac Fibrosis
Conclusions
The present study revealed a circulating transcriptome signature that reflects the pathogenesis of CF. The expression profiles of circulating lncRNAs discriminated between patients with and without interstitial myocardial fibrosis. LncRNAs ENSGehz746.10420258017.1 and ENSGehz746.10420265401.1, in particular, are novel biomarkers with potential to facilitate clinical diagnosis of myocardial fibrosis.

Abstract
AIMS The concept of using specific dietary components to selectively modulate the gut microbiota to confer a health benefit, defined as prebiotics, originated in 1995. In 2018, a group of scientists met at the International Scientific Association for Probiotics and Prebiotics annual meeting in Singapore to discuss advances in the prebiotic field, focussing on issues affecting functionality, research methodology and geographical differences. METHODS AND RESULTS The discussion ranged from examining scientific literature supporting the efficacy of established prebiotics, to the prospects for establishing health benefits associated with novel compounds, isolated from different sources. CONCLUSIONS While many promising candidate prebiotics from across the globe have been highlighted in preliminary research, there are a limited number with both demonstrated mechanism of action and defined health benefits as required to meet the prebiotic definition. Prebiotics are part of a food industry with increasing market sales, yet there are great disparities in regulations in different countries. Identification and commercialization of new prebiotics with unique health benefits means that regulation must improve and remain up-to-date so as not to risk stifling research with potential health benefits for humans and other animals. SIGNIFICANCE AND IMPACT OF STUDY This summary of the workshop discussions indicates potential avenues for expanding the range of prebiotic substrates, delivery methods to enhance health benefits for the end consumer and guidance to better elucidate their activities in human studies.

Abstract
Objective: To investigate the cardiovascular magnetic resonance (CMR) imaging characteristics and influence factors of aortic insufficiency (AI) patients with myocardial fibrosis. Method: This retrospective study included 59 AI patients who received CMR and transthoracic echocardiography (TTE) examinations from June 2011 to February 2015. AI patients were divided into 2 groups: bicuspid aortic valve (BAV) group (n=30) and non-BAV group (n=29). Patients were also divided into late gadolinium enhancement (LGE) group (n=27) and non-LGE group (n=32). The baseline clinical characteristics were collected through electronic medical records. Hemodynamic parameters such as grade of AI, cardiac functional parameters and LGE mass fraction (LGE%) were measured by CMR post-processing analysis. Kappa test was used to assess the consistency of AI severity between CMR and TTE, and the multivariate logistic regression analysis was performed to evaluate influence factors of myocardial fibrosis in AI patients. Results: (1) 56 (94.9%) patients were male, and the mean age was (44.2±11.0) years old. There was no significant difference in age and gender, hypertension, hyperlipidemia, alcoholic consumption between BAV and non-BAV group (all P>0.05). There were a higher proportion of smoking history (P=0.008), a lower body mass index (BMI) (P=0.020) in the LGE group than in the non-LGE group. (2) The accuracy of CMR in diagnosis of BAV was 96.7% (29/30) compared to the gold standard. In the BAV group, 20 patients (66.7%) were with fusion of left and right cusp (L-R), 5 patients (16.7%) were with fusion of right and noncoronary cusp (R-N), 5 patients (16.7%) were with fusion of left and noncoronary cusp (L-N); patients with BAV had larger left ventricular end diastolic volume index (LVEDVi), left ventricular end systolic volume index (LVESVi), higher proportion of LGE and lower left ventricular ejection fraction (LVEF) than those in non-BAV group (all P<0.05). There were 19 patients with BAV in the LGE group, the cases of L-R, R-N, L-N were 10 (52.6%), 5 (26.3%), and 4 (21.1%), respectively. In the non-LGE group, patients with BAV of L-R, R-N, L-N were 10 (90.9%), 0, and 1 (9.1%), respectively. Patients with LGE had lower body surface area (BSA), LVEF and larger LVEDVi, LVESVi, left ventricular mass index (LVMi) and higher proportion of BAV compared patients without LGE. In addition, the proportion of moderate and severe AI patients was significantly higher in BAV group than in non-BAV group (P=0.009). (3) The consistency of CMR and TTE in evaluating the severity of AI patients: the agreement between TTE and CMR regarding AI severity was satisfactory (kappa value was 0.624, 95%CI 0.402-0.831, P<0.001). (4) The linear regression analysis demonstrated a negative correlation between LVEF and LGE% in BAV and non-BAV group (P<0.001). The multivariate logistic regression analysis showed that the presence of BAV was an independent risk factor of left ventricucar fibrosis (OR=5.050, 95%CI 1.220-20.908, P=0.025) after adjustment for LVEF, hypertension, LVEDVi and LVMi. Conclusion: Multi-parametric CMR provides a satisfactory noninvasive tool for estimation of myocardial fibrosis and ventricular remodeling in patients with AI, and BAV is an independent risk factor for myocardial fibrosis in patients with AI.

Abstract
Objective: To observe the histopathological features of different opportunistic infections and tumors of the intestinal mucosa in AIDS patients, and to explore the correlation between different lesions and CD4+ T lymphocyte levels. Methods: Colonic mucosal biopsy specimens of 263 patients with clinically diagnosed AIDS and abdominal pain, diarrhea, blood in the stool and other gastrointestinal symptoms were collected from Beijing Ditan Hospital from 2010 to 2018. There were 232 males and 31 females, with age range 10-81 (mean 40±13) years. HE staining, histochemical special staining, immunohistochemical staining, and in-situ hybridization were used to detect the expression of different opportunistic infection pathogens, tumors and CD4+ T lymphocytes. Peripheral blood was also taken for CD4+ T lymphocytes, CD8+ T lymphocytes, HIV viral load and routine indicators. Results: The cohort included 263 intestinal mucosal biopsy specimens. There were 175 cases (66.5%) of non-specific inflammation, and pathogens were detected in 41 cases (15.6%), including 20 cases(7.6%) of cytomegalovirus (CMV) infection, 12 cases (4.6%) of mycobacterial infection, eight cases (3.0%) of amoeba infestation, and one case (0.3%) of talaromycesmarneffei infection; there were also 41 (15.6%) neoplastic lesions including 25 cases (9.5%) of intraepithelial neoplasia, 10 cases (3.8%) of adenocarcinoma and squamous cell carcinoma, six cases (2.3%) of lymphoma; and six cases (2.3%) of ulcerative colitis. The peripheral blood CD4+T lymphocyte levels of patients with CMV, mycobacteria and talaromycesmarneffei were less than 200/μL; the peripheral blood CD4+ T lymphocyte level (P<0.01) and intestinal mucosa CD4+T lymphocytes (P<0.01) were all significantly lower than those in patients with non-specific inflammation. The peripheral red blood cells and hemoglobin levels of patients with CMV and mycobacterial infection (P<0.01), adenocarcinoma and squamous cell carcinoma (P<0.05) were significantly lower than those of non-specific inflammation patients. Conclusions: Pathologic examination of intestinal mucosa can identify specific infections and neoplastic lesions in AIDS patients; the most common lesions are non-specific inflammation, and CMV infection is the most common opportunistic infections; CMV, mycobacteria and talaromycesmarneffei infections are associated with decreased levels of CD4+ T lymphocytes in peripheral blood and intestinal mucosa; entamoeba histolytica infestation and non-HIV-related neoplastic lesions such as intraepithelial neoplasia, adenocarcinoma and squamous cell carcinoma are not associated with changes in AIDS immune function.

Abstract
Objective: To evaluate the clinical and cardiac magnetic resonance (CMR) features of apical hypertrophic cardiomyopathy (ApHCM) patients complicating with left ventricular apical aneurysm (LVAA). Methods: CMR confirmed 25 ApHCM patients complicating with LVAA from January 2010 to December 2017 in Fuwai hospital were included in this study, and the baseline clinical data and CMR characteristics were retrospectively analyzed. There were 14 pure ApHCM (hypertrophy limited at the apical segments) complicating with LVAA patients and 11 mixed ApHCM (predominantly apical hypertrophy along with thickening of contiguous non-apical left ventricular region) with LVAA patients. Results: In this patient cohort,age of 84% (21/25) patients ranged between 20-70 years old, and 68% (17/25) were male. There were 68% (17/25) patients with complaint of chest distress symptom, 56% (14/25) with complaint of chest pain, 32% (8/25) with complaint of palpitation,16% (4/25) with complaint of dyspnea, and 12% (3/25) presented as syncope. ST-T segment changes of electrocardiogram were observed in all patients, and giant negative T waves were detected in 80% patients (20/25). The rate of missed diagnosis by echocardiography for detecting ApHCM and LVAA was 16% (4/25) and 68% (17/25), respectively. CMR showed discrete thin-walled dyskinetic or akinetic segment of the most distal portion of the left ventricular chamber in ApHCM patients with LVAA. Transmural late gadolinium enhancement of the aneurysmal rim was detected in 76% (19/25) patients, and the maximum transverse dimension of aneurysm was bigger in patients with transmural late gadolinium enhancement than in patients without transmural late gadolinium enhancement ((22.0±10.8)mm vs. (11.7±4.0) mm, P=0.033). Conclusion: ApHCM with LVAA patients have distinct cardiac clinical features, and CMR is the most useful tool for the accurate and objective evaluation of this disease.
