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.

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.

Abstract
OBJECTIVE The aim of this study was to explore the promoting effect of long non-coding ribonucleic acid p21 (lncRNAp21) on the osteogenic differentiation of mesenchymal stem cells in the rat model of osteoporosis (OP) through the Wnt/β-catenin signaling pathway. MATERIALS AND METHODS A total of 30 healthy female rats were selected and randomly divided into three groups, including the lncRNAp21 group, OP model group (model group) and normal group. Rats in the lncRNAp21 group were given a certain quantity of lncRNAp21 inhibitors for gavage. Rats in the model group were regularly given 0.9% NaCl for gavage every day after the removal of bilateral ovaries. Meanwhile, rats in the normal group were fed normally without any changes. Bone mineral density (BMD) was measured after 12 weeks of modeling. The levels of procollagen type I N-terminal propeptide (PINP), serum estradiol (E2), osteocalcin (OC), bone alkaline phosphatase (BALP), C-terminal cross-linking telopeptide of type I collagen (CTX) and tartrate-resistant acid phosphatase 5b (TRACP-5b) in the bone and serum of rats were measured by enzyme-linked immunosorbent assay (ELISA). Besides, quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) and Western blotting were adopted to detect the mRNA and protein expressions of Wnt1 and β-catenin in bone tissues, respectively. RESULTS Compared with the normal group and lncRNAp21 group, the serum level of E2 in the model group decreased significantly (p<0.05). BMD and phosphorus (P) content in the model group were both markedly lower than those of the normal group and lncRNAp21 group. However, calcium (Ca) content was remarkably higher than that of the normal group and lncRNAp21 group (p<0.05). The serum levels of bone resorption markers (including TRACP-5b and CTX) in the model group were prominently higher than those of the normal group (p<0.05). However, the levels of the two markers in the lncRNAp21 group were significantly lower than the model group (p<0.05). Additionally, bone formation markers (including OC, PINP and BALP) in the serum of rats in the model group were notably higher than those in the normal group and lncRNAp21 group (p<0.05). QRT-PCR and Western blotting results revealed that the mRNA and protein expressions of Wnt1 and β-catenin in bone tissues of the model group were markedly lower than those of the normal group. However, the mRNA and protein expressions of Wnt1 and β-catenin in the lncRNAp21 group were remarkably higher than the model group (p<0.05). CONCLUSIONS Low expression of lncRNAp21 activates the Wnt/β-catenin signaling pathway by increasing E2 secretion, eventually stimulating bone formation and increasing osteogenic differentiation of mesenchymal stem cells in OP model rats.

Abstract
Perillaldehyde (PAE), a natural monoterpenoid agent extracted from Perilla frutescence, PAE has been reported to present various physiological capabilities, such as anti-inflammation, anti-oxidative and anti-fungal. In this study, we show that PAE exhibits strong antifungal activity against Candida albicans (C. albicans). C. albicans, a fungal pathogen with high incidence of antifungal resistance in clinical settings, is the major cause of oropharyngeal candidiasis (OPC). OPC is characterized by inflammatory immunological responses to fungal infections. Our in vitro results show PAE inhibited several virulence attributes of C. albicans including biofilm formation, yeast-to-hyphal transition and secreted aspartic proteinases (SAPs) gene expression. Using an experimental murine model of OPC, we found that PAE inhibited NLRP3 inflammasome assembly, reduced the excessive accumulation of ROS and prevented the p65 transfer in nuclear; processes all leading to reduced inflammation burden in the host. Together, this supports use PAE as a promising new agent to improve OPC.

Abstract
Background:Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of unknown etiology that affects mostly young women. Multiorgan complications and prolonged treatment significantly cause physical and mental stress in patients. Improving patients’ quality of life (QOL) in SLE treatment is essential. We examined the treatment effects on disease activity and QOL of SLE patients.Objectives:In recent years, lupus low disease activity state (LLDAS) has been proposed as a treatment target for SLE. Patients who achieve LLDAS have a low recurrence rate for lupus and a low risk of serious complications (1). The aim of this study is to investigate whether achieving LLDAS reduces not only recurrence rate and complications of SLE but also improves patients’ QOL.Methods:A total of 104 SLE patients were enrolled in our prospective SLE registry study (Juntendo, Multi-center, Prospective cohort for investigation of clinical course and outcome in SLE: JUMP) conducted at our institution. SLE was diagnosed using the American College of Rheumatology (ACR) 1982 criteria (revised in 1997). QOL was evaluated using the standard version of the 36-item short form health survey version 2 (SF36v2). Participants were divided into the LLDAS achievement and non-achievement groups, and the characteristics of each group including results of SF36v2 were examined.Results:This study included 104 SLE patients, 94 female and 10 male, and the average age and disease duration were 46.4±13.8 and 14.5±11.3 years, respectively. The average corticosteroid dose was 8.0±17.4 mg/day in terms of prednisolone, and anti-dsDNA antibody titer was 16.8±38.5 IU/ml. Of the 104 patients, 57 achieved LLDAS. The subscale’s standard scoring using SF36v2 for role physical (RP) was 78.9±24.0 and 64.6±27.6 (P<0.01), general health (GH) was 50.0±17.0 and 42.0±19.3 (P<0.05), vitality (VT) was 55.8±15.8 and 38.0±24.1 (P<0.01), social functioning (SF) was 82.0±20.7 and 66.5±26.3 (P<0.01), role emotional (RE) was 89.0±16.1 and 73.4±28.1 (P<0.01), and mental health (MH) was 72.4±15.9 and 58.3±21.8 (P<0.01) in the LLDAS achievement and non-achievement groups, respectively. Furthermore, scoring based on the national standard value in the LLDAS achievement group showed that two categories were >50. However, in the LLDAS non-achievement group, all categories were <50. In particular, RP, GH, VT, SF, RE, and MH of the LLDAS achievement group had significantly higher scores than the LLDAS non-achievement group (RP and GH: p<0.05 and VT, SF, RE and MH: p<0.01).Conclusion:Results of examining the association between LLDAS and QOL using SF36v2 in SLE patients showed that patients who achieved LLDAS had significantly better standard statistical scores in many subscale categories. Thus, LLDAS achievement as a treatment target for SLE patients greatly contributes to improving patients’ QOL.References:[1]Franklyn K, et al.

Abstract
Abstract
Introduction
The aim of this study was to develop a predicting model for the moderate-to-severe obstructive sleep apnea (OSA) by using advanced tree models.
Methods
We retrospectively investigated the medical records of patients who undertaken overnight polysomnography (PSG) at our sleep disorders center. We divided the data to a training set (70%) and a test set (30%), randomly. We made a random forest and a XGBoost model to predict the moderate-to-severe OSA (apnea hyponea index [AHI] ≥ 15/h) by using the training set, and then applied each models to the test set. To compare the fitness of the models, we used an accuracy, and an area under curve (AUC).
Results
Finally, 1,426 patients (AHI < 5:AHI ≥ 15= 464:962) were enrolled. The random forest model showed an accuracy of 0.79, and AUC of 0.82. In the random forest model, the sleep apnea scale of the sleep disorders questionnaire (SA-SDQ), age, neck circumference, male sex, body mass index (BMI), hypertension, and hyperlipidemia appeared in order of a variance importance. The XGBoost model showed an accuracy of 0.75 and AUC of 0.79.
Conclusion
The random forest model to predict moderate-to-severe OSA showed better performance compared to the XGBoost model. The further study for validation is required.

Abstract
Abstract
Introduction
The present study aimed to examine the association between chronotype, sleep duration, weekend catch-up sleep (CUS) duration, and depression among Korean high school students.
Methods
A total of 8,565 high school students who were analyzed from 15 nationwide districts in South Korea completed an online self-report questionnaire. Depressive mood was assessed using the Korean version of the Beck Depression Inventory. The following sleep characteristics were assessed: weekday and weekend sleep durations, weekend CUS duration, chronotype, perceived sufficiency of sleep, self-reported snoring and sleep apnea, daytime sleepiness, and sleep environment. Age, sex, body mass index, number of private classes, and proneness to internet addiction were also measured. Logistic regression analysis was conducted to compute odds ratios for the association between depression and sleep characteristics, after controlling for relevant covariates.
Results
The prevalence of depression (BDI ≥ 16) was 1,794 (20.9%). In the analyses of multivariate logistic regression, the late chronotype (odds ratio [OR], 1.71; 95% CI, 1.47-1.99), female (OR, 2.24; 95% CI, 1.99-2.53), underweight (OR, 1.27; 95% CI, 1.02-1.57) and obesity (OR, 1.41; 95% CI, 1.13-1.75), weekday sleep duration (OR, 0.86; 95% CI, 0.81-0.91), weekend CUS duration ≥ 2 hours (OR, 0.68; 95% CI, 0.55-0.85), ESS (OR, 1.08; 95% CI, 1.07-1.10), much (OR, 2.15; 95% CI, 1.63-2.84) and insufficient (OR, 1.71; 95% CI, 1.46-2.01) perceived sleep, snoring (OR, 1.27; 95% CI, 1.11-1.46) and witnessed apnea (OR, 2.10; 95% CI, 1.75-2.52), increased internet addiction (OR, 1.06; 95% CI, 1.05-1.06), high number of private education (OR, 0.76; 95% CI, 0.60-0.95), and poor sleep environment (OR, 1.86; 95% CI, 1.56-2.21) were associated with depression.
Conclusion
Eveningness preference, insufficient weekday sleep duration, short weekend CUS duration, and self-reported snoring and sleep apnea were associated with an increased risk for depression.

Abstract
Objective: To explore the effect of standardized surgical treatment and multidisciplinary treatment strategy on the treatment outcomes of gastric cancer patients. Methods: A single-center cohort study was carried out. Clinicopathological and long-term follow up data of primary gastric cancer patients were retrieved from the database of Surgical Gastric Cancer Patient Registry (SGCPR) in West China Hospital of Sichuan University. Finally, 4516 gastric cancer patients were included and were divided into three groups according to time periods (period 1 group: exploration stage of standardized surgical treatment, 2000 to 2006, 967 cases; period 2 group: application stage of standardized surgical treatment, 2007 to 2012, 1962 cases; period 3 group: optimization stage of standardized surgical treatment and application stage of multidisciplinary treatment strategy, 2013 to 2016, 1587 cases). Differences in clinical data, pathologic features, and prognosis were compared among 3 period groups. Follow-up information was updated to January 1, 2020. The overall follow-up rate was 88.9% (4016/4516) and median follow-up duration was 51.58 months. Survival curve was drawn by Kaplan-Meire method and compared with log-rank test. Univariate and multivariate analyses were performed by Cox proportional hazards model. Results: There were significant differences among period 1, period 2 and period 3 groups in the rates of D2/D2+ lymphadenectomy [14.4%(139/967) vs. 47.2%(927/1962) vs. 75.4%(1197/1587), χ(2)=907.210, P<0.001], in the ratio of proximal gastrectomy [19.8%(191/967) vs. 16.6%(325/1962) vs. 8.2%(130/1587), χ(2)=100.020, P<0.001], and in the median intraoperative blood loss (300 ml vs. 100 ml vs. 100 ml, H=1126.500, P<0.001). Besides, the increasing trend and significant difference were also observed in the median number of examined lymph nodes among period 1, period 2 and period 3 groups (14 vs. 26 vs. 30, H=987.100, P<0.001). Survival analysis showed that the 5-year overall survival rate was 55.3% in period 1, 55.2% in period 2 and 62.8% in period 3, and significant difference existed between period 3 and period 1 (P=0.004). The Cox proportional hazards model analysis showed that treatment period (period 3, HR=0.820, 95%CI: 0.708 to 0.950, P=0.008), postoperative chemotherapy (HR=0.696, 95%CI: 0.631 to 0.768, P<0.001) and mid-low gastric cancer (HR=0.884, 95%CI: 0.804 to 0.973, P=0.011) were good prognostic factors. Whereas old age (≥65 years, HR=1.189, 95%CI: 1.084 to 1.303, P<0.001), palliative resection (R1/R2, HR=1.538,95%CI: 1.333 to 1.776, P<0.001), large tumor size (≥5 cm, HR=1.377, 95%CI: 1.239 to 1.529, P<0.001), macroscopic type III to IV (HR=1.165, 95%CI: 1.063 to 1.277, P<0.001) and TNM stage II to IV(II/I:HR=1.801,95%CI:1.500~2.162,P<0.001;III/I:HR=3.588, 95%CI: 3.028~4.251, P<0.001; IV/I: HR=6.114, 95%CI: 4.973~7.516, P<0.001) were independent prognostic risk factors. Conclusion: Through the implementation of standardized surgical treatment technology and multidisciplinary treatment model, the quality of surgery treatment and overall survival increase, and prognosis of gastric cancer patients has been improved.

Abstract
INTRODUCTION Cancer patients receiving chemotherapy are a high risk of VTE, yet the importance of thromboprophylaxis for cancer patients that are at high risk of developing VTE is still controversial. AIM To calculate the benefits and harms of thromboprophylaxis, compared to placebo, in ambulatory high-risk cancer patients that are receiving chemotherapy. METHODS We searched PubMed, Embase, Web of Science, the Cochrane Library, Cochrane Central Register of Controlled Trials, Chinese Biomedical Literature Database, WANFANG Data, Chinese National Knowledge Infrastructure and Chinese Scientific Journal Database for randomized controlled trials (RCTs) describing benefits and harms of thromboprophylaxis. Statistical analysis was performed using Stata software (version 15.1). RESULTS We included six studies, which contained a total of 3240 cancer patients with thromboprophylaxis and 2874 cancer patients without thromboprophylaxis. Thromboprophylaxis was effective in high-risk patients with two points or higher (RR 0.51, 95% CI 0.36-0.71, I2 = 0.0%, P = 0.526). It was associated with an increase in bleeding events (RR 1.65, 95% CI 1.14-2.40, I2 = 0.0%, P = 0.498) and was mainly efficient in reducing the risk of pulmonary embolism (RR 0.56, 95% CI 0.33-0.96, I2 = 0.0%, P = 0.263). The risk of major (RR 1.85, 95% CI 0.87-3.94, I2 = 0.0%, P = 0.888) and non-major (RR 1.59, 95% CI 0.96-2.62, I2 = 16.3%, P = 0.303) bleeding showed no significant difference with or without thromboprophylaxis. There was no reduction in all-cause mortality with thromboprophylaxis (RR 0.95, 95% CI 0.78-1.18, I2 = 22.0%, P = 0.277). CONCLUSION Thromoboprophylaxis is effective and safe in cancer patients that are at high risk for developing VTE with chemotherapy.

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
Perillaldehyde (PAE), an essential oil in Perilla plants, serves as a safe flavor ingredient in foods, and shows an effectively antifungal activity. Reactive oxygen species (ROS) accumulation in Aspergillus flavus plays a critical role in initiating a metacaspase-dependent apoptosis. However, the reason for ROS accumulation in A. flavus is not yet clear. Using transcriptome sequencing of A. flavus treated with different concentrations of PAE, our data showed that the ROS accumulation might have been as a result of an inhibition of energy metabolism with less production of reducing power. By means of GO and KEGG enrichment analysis, we screened four key pathways, which were divided into two distinct groups: a downregulated group that was made up of the glycolysis and pentose phosphate pathway, and an upregulated group that consisted of MAPK signaling pathway and GSH metabolism pathway. The inhibition of dehydrogenase gene expression in two glycometabolism pathways might play a crucial role in antifungal mechanism of PAE. Also, in our present study, we systematically showed a gene interaction network of how genes of four subsets are effected by PAE stress on glycometabolism, oxidant damage repair, and cell cycle control. This research may contribute to explaining an intrinsic antifungal mechanism of PAE against A. flavus.

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.
