Abstract
Castration-resistant prostate cancer (CRPC) threatens the health of men in general and no effective therapeutics currently exists for the treatment of CRPC. It is therefore of great importance to find a novel molecule that can be a biomarker and a therapeutic target for CRPC. First, we found that the serum fibrinogen gamma (FGG) levels in patients with CRPC were significantly higher than those with localized prostate cancer (PCa) through iTRAQ proteomics and ELISA experiments. Immunohistochemistry, quantitative real-time polymerase chain reaction and western blot also showed an increase of FGG expression in CRPC tissues and cells. Then we proved the proliferation, invasion and migration ability of CRPC cells were significantly reduced after FGG knockdown. The number of apoptotic cells increased at least sixfold after FGG silencing, and was observed in conjunction with an upregulation of p53, caspase 3, clea-caspase 3, and Bax, and a downregulation of Bcl2 and survivin. FGG knockdown in DU145 cells resulted in smaller xenografts than control cells in a mouse model. and we established that FGG is modulated by IL-6 which was increased in CRPC patients via phosphorylation of STAT3. The data suggests that FGG may be a potential therapeutic target and prognostic marker for CRPC.

Abstract
Monoterpene Perillaldehyde (PAE) is a major component of the essential oil extracted from perilla plants (Perilla frutescens), which has been used as a leafy vegetable and a medicinal agent. PAE has gained a lot of attention in recent years because of its antifungal and other microbial activities and, human health benefits. PAE has also been used as food additives, perfume ingredients, and traditional medicine concoctions. Biological analyses of PAE have revealed that it has good antioxidant activities and can serve as organic fruit and food preservative. Animal studies indicated potent anticancer, anti-depressant, and anti-inflammatory effects of PAE. Also, PAE is certified "generally recognized as safe" (GRAS) and not mutagenic. However, moderation during usage is advisable, as minor adverse effects are associated with a very high dosage. Despite the newly reported findings, its properties have not been thoroughly summarized and reviewed. Also, clinical trials and official large-scale field applications of PAE in the agricultural sectors are yet to be reported. In this review, updated PAE research progress was provided, focusing on its antifungal and other antimicrobial properties and the mechanisms behind it, phytochemical profile, pharmacological effects, and safety concerns.HighlightsIsolation and recovery techniques of PAE from perilla plants have been developed and improved in recent years.PAE is a potential anti-oxidant and antifungal agent that can be widely used in the food industry.PAE can be developed into drug ingredients for pharmaceutical industries due to its anti-inflammatory, anti-cancer and anti-depressant activities.PAE can be safely used in human when low and moderate dosage is used.

Abstract
Since 2015 when the transmission of schistosomiasis was controlled in China, the country has been moving towards elimination of schistosomiasis, with the surveillance-response as the main interventions for schistosomiasis control. During the period of the 13th Five-Year Plan, the transmission of schistosomiasis had been interrupted in four provinces of Sichuan, Jiangsu, Yunnan and Hubei and the prevalence of schistosomiasis has been at the historically lowest level in China. As a consequence, the goal set in The 13th Five-Year National Schistosomiasis Control Program in China is almost achieved. However, there are multiple challenges during the stage moving towards elimination of schistosomiasis in China, including the widespread distribution of intermediate host snails and complicated snail habitats, many types of sources of Schistosoma japonicum infections and difficulty in management of bovines and sheep, unmet requirements for the current schistosomiasis control program with the currently available tools, and vulnerable control achievements. During the 14th Five-Year period, it is crucial to consolidate the schistosomiasis control achievements and gradually solve the above difficulties, and critical to provide the basis for achieving the ultimate goal of elimination of schistosomiasis in China. Based on the past experiences from the national schistosomiasis control program and the challenges for schistosomiasis elimination in China, an expert consensus has been reached pertaining to the objectives, control strategy and measures for The 14th Five-Year National Schistosomiasis Control Program in China, so as to provide insights in to the development of The 14th Five-Year National Schistosomiasis Control Program in China.

Abstract
Schistosomiasis was once endemic in 12 provinces (municipalities, autonomous regions) along and south of the Yangtze River basin, which seriously damages human health and hinders socioeconomic developments in China. Following the concerted efforts for 70 years, remarkable achievements have been gained in the national schistosomiasis control program of China. However, there are still multiple challenges for elimination of schistosomiasis in the country. This paper describes the current status of schistosomiasis and the challenges during the progress towards the elimination of schistosomiasis, and proposes the goals, key points and research priorities of schistosomiasis control in China during the 14th Five-Year Plan Period.

Abstract
Wolbachia-induced reproductive regulation in hosts has been used to control pest populations, but little is known about the molecular mechanism underlying Wolbachia regulation of host genes. Here, reproductive regulation by Wolbachia in the spider mite Tetranychus truncatus was studied at the molecular level. Infection with Wolbachia resulted in decreasing oviposition and cytoplasmic incompatibility in T. truncatus. Further RNA-seq revealed genes regulated by Wolbachia in T. truncatus. Real-time quantitative polymerase chain reaction (qPCR) showed that genes, including chorion protein S38-like and Rop were down-regulated by Wolbachia. RNA interference (RNAi) of chorion protein S38-like and Rop in Wolbachia-uninfected T. truncatus decreased oviposition, which was consistent with Wolbachia-induced oviposition decrease. Interestingly, suppressing Rop in Wolbachia-infected T. truncatus led to increased Wolbachia titres in eggs; however, this did not occur after RNAi of chorion protein S38-like. This is the first study to show that chorion protein S38-like and Rop facilitate Wolbachia-mediated changes in T. truncatus fertility. In addition, RNAi of Rop turned the body colour of Wolbachia-uninfected T. truncatus black, which indicates that the role of Rop is not limited to the reproductive regulation of T. truncatus.

Abstract
OBJECTIVE Non-small cell lung cancer (NSCLC) is one of the most common malignant tumors in the world and its 5-year survival rate is very low. Long non-coding RNA X-inactive specific transcript (lncRNA XIST) has been demonstrated to play vital roles in NSCLC, but the exact molecular mechanisms underlying NSCLC still need to be further explored. PATIENTS AND METHODS Quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) was performed to detect the expression of XIST, miR-212-3p and Casitas B-lineage proto-oncogene like 1 (CBLL1). Dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were conducted to analyze the relationship among XIST, miR-212-3p and CBLL1. Cell Counting Kit-8 (CCK-8) assay and transwell invasion assay were carried out to evaluate cell proliferation, migration and invasion, respectively. Western blot analysis was conducted to examine the protein expression of CBLL1, E-cadherin, N-cadherin and Vimentin. Murine xenograft assay was conducted to explore the role of XIST in vivo. RESULTS Expression levels of XIST and CBLL1 were markedly upregulated, while the miR-212-3p level was markedly downregulated in NSCLC tissues and cells. MiR-212-3p was identified as a direct target of XIST, and miR-212-3p was predicted to target CBLL1. XIST knockdown repressed NSCLC cell proliferation, migration, invasion and epithelial-mesenchymal transition (EMT) in vitro, and suppressed tumor growth in vivo, while miR-212-3p inhibition restored the effects. Furthermore, CBLL1 overexpression could abolish the effects of miR-212-3p overexpression on NSCLC cell proliferation, migration, invasion and EMT in vitro. CONCLUSIONS XIST was significantly decreased in NSCLC tissues and cells, and XIST knockdown suppressed the proliferation, migration, invasion and EMT of NSCLC cells by miR-212-3p/CBLL1 axis. These findings facilitated our understanding of lncRNA regulation in NSCLC.

Abstract
Sentinel lymph node (SLN) biopsy is typically offered to patients with primary cutaneous melanomas (PCMs) of ≥ 1 mm depth, but not all SLNs are positive using this cutoff. To ascertain whether positivity is genetically regulated, genetic analysis was performed using an augmented enrichment-based next-generation DNA and RNA sequencing assay in SLN-negative (Group 1, n = 8, mean depth 1.3 mm) and SLN-positive PCMs (controls, Group 2, n = 4, mean depth 1.4 mm). In Group 1, the mean number of mutations was 21 (range 3-48) with the most frequent mutations occurring in NF1 (75%) followed by TP53 (63%), CDKN2A and BRAF (38%), and NRAS (25%), while in Group 2, the ean number of mutations was 9.5 (range 5-18) with mutations in NRAS and BRAF being the most frequent (50%) followed by those in ATM, CDKN2A, CDKN2B, and NOTCH1 (25%). Increased frequency of NF1-inactivating mutations in Group 1 provides provocative early data that the presence of NF1 mutations might confer a less aggressive phenotype.

Abstract
As a pathogenic fungus, Aspergillus flavus can produce carcinogenic aflatoxins (AFs), which poses a great threat to crops and animals. Msb2, the signalling mucin protein, is a part of mitogen‐activated protein kinase (MAPK) pathway which contributes to a range of physiological processes. In this study, the roles of membrane mucin Msb2 were explored in A. flavus by the application of gene disruption. The deletion of msb2 gene (Δmsb2) caused defects in vegetative growth, sporulation and sclerotia formation when compared to WT and complement strain (Δmsb2C) in A. flavus. Using thin‐layer chromatography (TLC) and high‐performance liquid chromatography (HPLC) analysis, it was found that deletion of msb2 down‐regulated aflatoxin B1 (AFB1) synthesis and decreased the infection capacity of A. flavus. Consistently, Msb2 responds to cell wall stress and osmotic stress by positively regulating the phosphorylation of MAP kinase. Notably, Δmsb2 mutant exhibited cell wall defect, and it was more sensitive to inhibitor caspofungin when compared to WT and Δmsb2C. Taking together, these results revealed that Msb2 plays key roles in morphological development process, stresses adaptation, secondary metabolism and pathogenicity in fungus A. flavus.

Abstract
Abstract
Background
The ESC 0/1-hour algorithm using high sensitivity troponin (ESC 0/1-h) is a rapid triage protocol for diagnosing acute coronary syndrome, however the classification performance of the algorithm in the US population is uncertain. Further, evidence for the use of ESC 0/1-h in the long-term diagnosis of major adverse cardiovascular events (MACE) remains limited.
Purpose
To evaluate the performance of the ESC 0/1-h algorithm in diagnosing 90-day MACE in a diverse US cohort.
Methods
In this prospective, multicenter, observational cohort study, adult emergency department patients who were evaluated for suspected ACS were enrolled at eight sites in the US. Serial 1-hour blood samples were collected and high sensitivity troponin T (hs-cTnT) concentrations were measured in a central laboratory using the hs-cTnT assay. Primary outcome included major adverse cardiovascular events (MACE) within 90 (+30) days of enrollment. MACE defined as myocardial infarction (MI), cardiovascular or uncertain death, and coronary revascularization. Presence of MI and cardiovascular death were adjudicated by independent reviewers blinded to hs-cTnT results. Each participant was stratified to one of three risk groups as determined by ESC 0/1-h algorithm. Diagnostic classification performance metrics with exact confidence intervals (i.e. negative predictive value [NPV], positive predicted value [PPV], sensitivity, and specificity) were evaluated for each risk group where appropriate.
Results
Among 1430 eligible participants, 45.8% (655/1430) were women and 36.6% (524/1430) were African American with a mean age of 57.6±12.8 years. MACE at 90-days occurred in 15.5% (221/1430). ESC 0/1-h stratified 59.5% (851/1430) subjects in Rule-Out range and 13.0% (186/1430) subjects in Rule-In range. The Rule-Out criteria had an NPV and sensitivity for 90-day MACE of 96.8% (95% CI: 95.4–97.9%) and 87.8% (95% CI: 82.7–91.8%), respectively. For 90-day cardiovascular death or MI, Rule-Out criteria had an NPV of 98.2% (95% CI: 97.1–99.0%) and sensitivity was 92.4% (95% CI: 87.8–95.7%). The Rule-In criteria had a PPV of 60.8% (95% CI: 53.3–67.8%) for both outcomes. Rule-In criteria had a specificity for 90-day MACE and 90-day cardiovascular death or MI of 94.0% (95% CI: 92.5–95.2%) and 94.1% (95% CI: 92.6–95.3%), respectively. Among the 27.5% (393/1430) participants classified in neither risk groups, the prevalence of 90-day MACE was 20.6% (81/393) and the prevalence of 90-day cardiovascular death or MI was 17.8% (70/393)
Conclusion
In a prospective, multicenter, US cohort, the ESC 0/1-h algorithm was unable to achieve a sufficiently high NPV to safely exclude the diagnosis of MACE within 90 days after emergency department presentation. New hs-cTn algorithms specific to the US population may be warranted.

Abstract
This study investigated the impact of dietary fiber from sweet potato residue (SPDF) on the diversity of the gut microbiota. An in vitro batch culture system simulating the human gut was used to understand the prebiotic role of SPDF. The results showed that SPDF mediated a significant increase in the concentrations of Bifidobacterium and Lactobacillus, whereas induced a significant decrease of Enterobacillus, Clostridium perfringens and Bacteroides. The prebiotic index and Bifidobacterium/Enterobacillus value were also significantly increased in SPDF groups compared to those of the control group, suggesting that SPDF had prebiotic effects. Furthermore, to investigate the effects of SPDF on the intestinal microecosystem, diets containing different concentrations of SPDF were used to feed Wistar rats for 4 weeks. 16S rRNA gene sequencing, short chain fatty acid quantification and physiochemical property analysis in the rat feces were then conducted. The results showed that SPDF significantly increased the Bacteroidetes to Firmicutes ratio at the phylum level and the amount of Akkermansia was also increased at the genus level, which was confirmed by qRT-PCR. The production of propionate and butyrate in the rat feces of both 3% and 15% SPDF groups was higher than that in the control group, which was further confirmed by the decrease of pH. Additionally, SPDF supplementation in this study resulted in a higher villus height to fossa depth ratio, which indicated improved digestion and absorption in the GI tract. Our findings support the utilization of SPDF from sweet potato residue in the development of potentially prebiotic food products for improving intestinal health.

Abstract
OBJECTIVE To investigate the spatio-temporal distribution characteristics of Oncomelania hupensis snail habitats in three cities of Suzhou, Wuxi and Changzhou along the Taihu Lake region, so as to provide technical supports for establishing a sensitive and highly effective surveillance and forecast system for schistosomiasis. METHODS Snail distribution data were collected from Suzhou, Wuxi and Changzhou cities from 1950 to 2018, and the changing trend for snail habitats were described over years. In addition, the clusters of snail habitats were detected using Kernel density analysis and SaTScan space-time scan analysis. RESULTS The number of snail habitats appeared a single-peak distribution in Suzhou, Wuxi and Changzhou cities from 1950 to 2018, which peaked in 1970 and then declined rapidly. There were 62.68% of snail habitats eliminated within 10 years after identification, of which 38.24% were eliminated at the year of identification. Kernel density analysis and SaTScan space-time scan analysis revealed that high-density clusters of snail habitats were mainly distributed in Kunshan City, Wuzhong District and Xiangcheng District from 1970 to 1980, and in Yixing City in 1990; since then, the clusters gradually shrank, and overall appeared a move from northeast to west of Taihu Lake. A total of 4 new clusters were detected after 1970, as revealed by space-time scanning of snail habitats. In current snail habitats, emerging snail habitats are mainly identified in Huqiu District (Dongzhu Town), Wuzhong District (Guangfu Town), Taicang City (Shaxi Town) and Jintan District, and re-emerging snail habitats are scattered in 7 districts. CONCLUSIONS The distribution of snail habitats are spatio-temporal aggregation in Suzhou, Wuxi and Changzhou cities. The monitoring and prediction of emerging and re-emerging snail habitats are the key points in the future.

Abstract
OBJECTIVE To uncover the biological role of long non-coding RNA (lncRNA) MAGI2-AS3 in the progression of non-small cell lung carcinoma (NSCLC) and its molecular mechanism. PATIENTS AND METHODS LncRNA MAGI2-AS3 level in NSCLC tissues and cell lines was determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Chi-square test was conducted to analyze the correlation between MAGI2-AS3 level and pathological characteristics of NSCLC patients. Survival analysis was performed in NSCLC patients with high expression or low expression of MAGI2-AS3. In vitro influences of MAGI2-AS3 on viability and invasive ability of A549 and PC9 cells were evaluated. MicroRNA-23a-3p (miRNA-23a-3p), the target gene of MAGI2-AS3 was determined through the dual-luciferase reporter gene assay. In a similar way, the target gene of miRNA-23a-3p was identified. Finally, the regulatory effect of MAGI2-AS3/miRNA-23a-3p/PTEN (gene of phosphate and tension homology deleted on chromosome ten) axis on cellular behaviors of NSCLC cells was assessed. RESULTS LncRNA MAGI2-AS3 was downregulated in NSCLC tissues and cell lines. Its level was closely related to tumor size, Tumor Node Metastasis (TNM) stage and distant metastasis of NSCLC patients. The worse prognosis was identified in NSCLC patients with low expression of MAGI2-AS3 relative to those with a high expression. Overexpression of MAGI2-AS3 markedly attenuated viability and invasive ability of A549 and PC9 cells. MiRNA-23a-3p was verified to be the target gene of MAGI2-AS3, and furthermore, PTEN was the target of miRNA-23a-3p. Overexpression of miRNA-23a-3p could reverse the inhibited viability and invasion in NSCLC cells overexpressing MAGI2-AS3. CONCLUSIONS MAGI2-AS3 is downregulated in NSCLC. Overexpression of MAGI2-AS3 suppresses the proliferative and invasive abilities of NSCLC via miRNA-23a-3p/PTEN axis.

Transcriptome Sequencing Revealed an Inhibitory Mechanism of Aspergillus flavus Asexual Development and Aflatoxin Metabolism by Soy-Fermenting Non-Aflatoxigenic Aspergillus. Int J Mol Sci 2020; 21:E6994.

Abstract
Aflatoxins (AFs) have always been regarded as the most effective carcinogens, posing a great threat to agriculture, food safety, and human health. Aspergillus flavus is the major producer of aflatoxin contamination in crops. The prevention and control of A. flavus and aflatoxin continues to be a global problem. In this study, we demonstrated that the cell-free culture filtrate of Aspergillus oryzae and a non-aflatoxigenic A. flavus can effectively inhibit the production of AFB1 and the growth and reproduction of A. flavus, indicating that both of the non-aflatoxigenic Aspergillus strains secrete inhibitory compounds. Further transcriptome sequencing was performed to analyze the inhibitory mechanism of A. flavus treated with fermenting cultures, and the results revealed that genes involved in the AF biosynthesis pathway and other biosynthetic gene clusters were significantly downregulated, which might be caused by the reduced expression of specific regulators, such as AflS, FarB, and MtfA. The WGCNA results further revealed that genes involved in the TCA cycle and glycolysis were potentially involved in aflatoxin biosynthesis. Our comparative transcriptomics also revealed that two conidia transcriptional factors, brlA and abaA, were found to be significantly downregulated, which might lead to the downregulation of conidiation-specific genes, such as the conidial hydrophobins genes rodA and rodB. In summary, our research provides new insights for the molecular mechanism of controlling AF synthesis to control the proliferation of A. flavus and AF pollution.

Abstract
OBJECTIVE To establish a recombinase-aided isothermal amplification (RAA) assay for nucleic acid detection of Schistosoma mansoni. METHODS The 121 bp highly-repeated sequence of S. mansoni was selected as the target gene fragment to be detected. The primers and fluorescent probes were designed using the Amplfix software, and a fluorescent RAA assay was established and optimized. The fluorescent RAA assay was performed to detect gradient diluent recombinant plasmids containing target gene fragment and different concentrations of S. mansoni genomic DNA to determine the sensitivity, and this assay was applied to detect the genomic DNA of S. japonicum, S. haematobium, Ancylostoma duodenale and Clonorchis sinensis to evaluate the specificity. RESULTS A fluorescent RAA assay was successfully established, which was effective to amplify the specific gene fragments of S. mansoni within 20 min at 39 ℃. The minimum detectable limit of the fluorescent RAA assay was 10 copies/μL using recombinant plasmids as templates and 0.1 fg/μL using S. mansoni genomic DNA samples as templates. The fluorescent RAA assays were all negative for detecting the genomic DNA from S. japonicum, S. haematobium, A. duodenale and C. sinensis. CONCLUSIONS A novel fluorescent RAA assay is successfully established, which is simple, rapid, sensitive and specific to detect genomic DNA of S. mansoni.
