Abstract
Abstract
Background
With demographic and epidemiologic transitions, China has become home to the greatest number of obese individuals in the world. Effective policy intervention requires a contemporary assessment of obesity across broad socio-demographic subgroups.
Purpose
We aim to assess the prevalence of overall and abdominal obesity by socio-demographic characteristics and the associations of these characteristics with obesity in China.
Methods
Using the data of 2.7-million community-dwelling participants aged 35–75 years in the China PEACE Million Persons Project, a nationwide cross-sectional screening project from 2014 to 2018, we calculated the prevalence of overall and abdominal obesity based on national guideline definitions (body mass index ≥28 kg/m2, waist circumference ≥85/90 cm for women/men). We examined 12 available socio-demographic variables that are potentially associated with obesity, in addition to self-reported co-morbidities, and quantified the associations of these socio-demographic characteristics with obesity using multivariable mixed models.
Results
The prevalence of overall and abdominal obesity were 15.8% and 37.6% in women and 15.0% and 36.3% in men (Figure). Compared to individuals with normal weight, those with overall obesity had a higher prevalence of hypertension, dyslipidemia, and diabetes (in women: by 30.4, 16.1, and 6.0 percent points; in men, by 29.9, 31.2, and 5.8 percent points). A similar pattern was observed with abdominal obesity. In women, those aged 55–64 years constituted the largest age group with overall and abdominal obesity (33.7% and 35.0%), while in men, those aged 45–54 and 55–64 years constituted the largest age group with overall obesity (30.4%) and abdominal obesity (30.5%), respectively. Older women were at substantially higher risk for obesity (e.g., adjusted relative risk [95% CI] of women aged 65–75 vs. 35–44 years: 1.29 [1.27–1.31] for overall obesity and 1.76 [1.74–1.77] for abdominal obesity) while older men were not. Higher education was associated with lower risk in women (e.g., those with college or university education vs. less than primary school: 0.47 [0.46–0.48] for overall obesity and 0.61 [0.60–0.62] for abdominal obesity) but higher risk in men (1.07 [1.05–1.10] and 1.17 [1.16–1.19]). In both women and men, current smoking was associated with lower risk for obesity, and current drinking was associated with higher risk, but the magnitude of associations was smaller in women than men.
Conclusions
In China, over one in seven individuals meet criteria for overall obesity, and one in three for abdominal obesity. Wide variation exists across socio-demographic subgroups. The associations of age and education with obesity are significant and differ by sex. Understanding obesity in contemporary China has broad domestic policy implications and provides a valuable international reference.

Abstract
BACKGROUND The prognostic values of the AJCC staging system for gastric cancer (GC-AJCC), the AJCC staging system for gastric neuroendocrine tumours (NET-AJCC) and the European Neuroendocrine Tumor Society (ENETS) system for gastric neuroendocrine carcinoma and mixed adenoneuroendocrine carcinoma (MA)NEC remain controversial. METHODS Data on patients with (MA)NEC from 21 centres in China were analysed. Different staging systems were evaluated by performing Kaplan-Meier survival analysis and calculating the concordance index (C-index) and Akaike information criterion (AIC). Based on three existing systems, a modified staging system (mTNM) was developed. RESULTS A total of 871 patients were included. In the GC-AJCC system, an overlap was noticed for pT2 and pT3 categories. Patients with stage IIIC disease had a similar prognosis to those with stage IV disease. The pT categories of the NET-AJCC system had a lower C-index and higher AIC than those of the other systems. In the ENETS system, there was a low proportion (0·2 per cent) of patients with stage IIIA and a high proportion (67·6 per cent) of stage IIIB disease. The mTNM system adopted the NET-AJCC pT and GC-AJCC pN and pM definitions, and was developed based on the ENETS stage definitions. The proportion of patients in each stage was better distributed and the mTNM system showed improved prognostic performance in predicting overall and disease-free survival. CONCLUSION The mTNM system offers more accurate prognostic value for gastric (MA)NEC than the AJCC or ENETS staging systems.

Abstract
OBJECTIVE Recent studies have discovered a class of circular RNAs (circRNAs), which are dysregulated in various tumors and participate in the regulation of tumor progression. In our research, we aim to research the function of circ-SMAD7 in the progression of glioma. PATIENTS AND METHODS Circ-SMAD7 expression was detected by quantitative Real Time Polymerase Chain Reaction (qRT-PCR) in glioma tissue patients. Pearson's Chi-square test was used to determine the association of circ-SMAD7 expression with several clinicopathological factors. Besides, cell proliferation assay, cell cycle assay, transwell assay, and Matrigel assay were conducted to detect the function of circ-SMAD7 in glioma. In addition, the interaction between circ-SMAD7 and proliferating cell nuclear antigen (PCNA) in glioma was studied by performing qRT-PCR and Western blot assay. RESULTS Circ-SMAD7 expression was observed in glioma tissues when compared with adjacent samples. The expression of circ-SMAD7 was associated with patients' WHO stage and KPS score. Cell proliferation was inhibited and cell cycle was regulated after circ-SMAD7 was downregulated in glioma cells. Besides, cell migration and invasion were inhibited after circ-SMAD7 was downregulated in glioma cells. In addition, the mRNA and protein expression of PCNA was repressed after circ-SMAD7 was knocked down in glioma cells. Furthermore, PCNA expression level positively correlated to circ-SMAD7 expression level in glioma samples. CONCLUSIONS Our study suggests that circ-SMAD7 promotes proliferation and metastasis of glioma via upregulating PCNA. Circ-SMAD7/ PCNA might be a novel therapeutic strategy in glioma.

Abstract
OBJECTIVE Recently, long noncoding RNAs (lncRNAs) have caught more attention for their role in the progression of many diseases. Among them, lncRNA GAS5 (Growth Inhibition Specificity 5) was studied in this research to identify how it affects the progression of atrial fibrillation (AF). PATIENTS AND METHODS In 40 patients with AF and 30 patients with sinus rhythm (SR), the GAS5 expression of the right atrial appendage (RAA) tissues was detected by the quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Moreover, the cell proliferation assay was conducted in AC16 cells transfected with GAS5 inhibitor and mimics, respectively. Furthermore, the qRT-PCR was performed to uncover the mechanism. RESULTS In the research, the expression of GAS5 in RAA tissues was decreased significantly in AF patients than that in SR ones. Moreover, overexpression of GAS5 inhibited cell growth in AC16 cells, while knockdown of GAS5 promoted cell growth in AC16 cells. In addition, further experiments revealed that ALK5 was a target of GAS5 and its expression in AF tissues negatively correlated to GAS5 expression. CONCLUSIONS These results indicate that GAS5 could inhibit cell proliferation of AF via suppressing ALK5, which may offer a new vision for interpreting the mechanism of AF development.

Abstract
Antibody levels after hepatitis B virus (HBV) vaccination may be affected by suppression of the immune system due to cancer therapy. As such, childhood acute lymphocytic leukaemia (ALL) survivors are at risk of HBV infection due to immunosuppression secondary to chemotherapy. However, the hepatitis B surface antibody (HBsAb)-seropositive rate of childhood ALL survivors after chemotherapy is unknown, and the need to revaccinate HBsAb-seronegative ALL survivors is not appreciated in China. To assess the changes in HBsAb before and after chemotherapy, we retrospectively analyzed clinical data from 547 patients treated with the Chinese Children Leukaemia Group (CCLG)-ALL 2008 protocol from 1 April 2008 to 30 August 2019. The results revealed that 416 patients (76·1%) were HBsAb-seropositive at diagnosis, and at the time of the cessation of chemotherapy, 177 patients (32·4%) were HBsAb-seropositive and 370 patients (67·6%) were HBsAb-seronegative. Interestingly, 11 patients who were HBsAb-seronegative at diagnosis converted to seropositive at the time of the cessation of chemotherapy. HBsAb titres were decreased after chemotherapy (P < 0·0001). Further, patients with higher HBsAb titres at diagnosis were more likely to maintain protective antibody titres at the completion of chemotherapy (P < 0·0001). The loss of antibody was more remarkable in younger patients (≤ 10 years) both at diagnosis (P = 0·009) and at the completion of chemotherapy (P = 0·006). In summary, this study showed that 67·6% of patients were HBsAb-seronegative at the time of the cessation of chemotherapy, which indicates that ALL survivors are at high risk of HBV. As a result, HBV revaccination after chemotherapy should be highly valued in ALL survivors.

Abstract
Objective: To analyze the immunophenotype and cytogenetic characteristics of primary plasma cell leukemia (pPCL), and to evaluate the efficacy of bortezomib and hematopoietic stem cell transplantation as main treatment. Methods: A retrospective cohort study was conducted including 42 pPCL patients admitted to Peking University People's Hospital from January 1998 to March 2019. All patients were followed up until December 31, 2019. The immunophenotype and cytogenetic characteristics were compared with historical data of multiple myeloma (MM). Thirty-nine patients were divided into bortezomib-based group (29 cases) and non-bortezomib group (10 cases). All patients were also divided into hematopoietic stem cell transplantation (HSCT) group (15 cases) and non-HSCT group (24 cases).Chi-square test was used for efficacy comparison, and Kaplan-Meier method was used for univariate prognostic analysis. Cox proportional hazards model was used for multi-variant analysis. Results: pPCL accounted for 2.6% of the total patients with plasma cell diseases during the same period. There were 22 males and 20 females, with a median age of 50 (30-77) years old at diagnosis. In immunophenotype analysis, tumor cells in pPCL patients also expressed CD38, CD138, CD45, which was similar as patients with MM. However the expression of CXCR4 were more frequently seen in pPCL(73.1% vs. 34.7%, P= 0.000), while intensity of CD9 and CD200 was lower (40.7% vs. 62.5%, P =0.028, 33.3% vs. 58.0%, P=0.021).Overall response rate of bortezomib-based therapy was superior to non-bortezomib therapy (69.0% vs.50.0%). The median survival was 18.2 (0.2-95.7)months, and the 1-and 2-year survival rates were 61.9% and 37.4%, respectively. Multivariate prognostic analysis suggested that age (P= 0.027) and efficacy(P= 0.035)were significantly correlated with survival.HSCT resulted in superior survival compared with chemotherapy alone(26.8 vs. 8.1 months, P=0.021). Conclusions: Immunophenotypes and cytogenetic abnormalities in patients with pPCL are different from those with multiple myeloma. Bortezomib based regimens improve response rate and survival of pPCL. Hematopoietic stem cell transplantation also predicts survival benefits.

Abstract
Objective: To investigate the efficacy and safety of daratumumab in relapsed and refractory multiple myeloma (RRMM). Methods: The efficacy and adverse events (AEs) of daratumumab based regimens were retrospectively analyzed in 37 patients with RRMM from Peking University People's Hospital, Beijing Hospital and Fu Xing Hospital affiliated to Capital Medical University in China. The deadline for inclusion was December, 2019. Results: Among the 37 patients, 35 patients were available for response evaluation. The overall response rate (ORR) was 68.6%, which was better in patients receiving 16 mg/kg daratumumab than in those with fixed doses of 800 mg daratumumab [ORR: 78.3%(18/23) vs. 40.0%(4/10)]. The percentage of infusion related reactions of daratumumab was 27.0%(10/37). The most common hematological AEs were lymphocytopenia and thrombocytopenia, with the incidences of grade 3 or more severe 59.5%(22/37) and 43.2%(16/37) respectively. Pulmonary infections(37.8%, 14/37) were the most common non-hematological AEs. One patient with positive hepatitis B surface antigen (HBsAg) and two patients dependent on dialysis were safely treated with daratumumab. Conclusion: Daratumumab is highly effective in relapsed and refractory multiple myeloma. Adverse reactions are mild and well tolerable.

Abstract
The aim of this study was to compare the dynamic changes of egg selenium (Se) deposition and deposition efficiency and to evaluate the efficacy of selenium-enriched yeast (SY) in laying hens over the 84 d feeding period after SY supplementation. A total of one thousand one hundred fifty-two 30-wk-old, Hy-Line Brown hens were randomly assigned to 1 of 6 groups (192 laying hens per group) with 6 replicates of 32 birds each, fed a basal diet (without Se supplementation), basal diet with 0.3 mg/kg of Se from sodium selenite (SS) or basal diets with 0.1, 0.2, 0.3, or 0.4 mg/kg of Se from SY, respectively. The results showed that the Se concentrations in the eggs and breasts from hens fed a SY-supplemented diet were significantly higher than those from hens fed a SS-supplemented diet or a basal diet (P < 0.001). There was a positive linear and quadratic correlation between Se concentrations in the eggs from hens fed a SY-supplemented diet and dietary Se supplementation on days 28, 56, and 84 (r2 = 0.931, 0.932, 0.976, P < 0.001; r2 = 0.946, 0.935, 0.976, P < 0.001), respectively. The Se deposition efficiency in whole eggs from hens fed a basal or SY-supplemented diet weresignificantly higher than those in eggs from hens fed a SS-supplemented diet on days 28, 56, and 84 (P < 0.001), respectively. In addition, there was a positive linear and quadratic correlation between Se concentrations in the eggs from hens fed SY-supplemented diet (r2 = 0.655, 0.779, 0.874, 0.781, P < 0.001; r2 = 0.666, 0.863, 0.944, 0.781, P < 0.001) or SS-supplemented diet (r2 = 0.363, P = 0.002; r2 = 0.440, P = 0.002) and number of feeding days. In conclusion, the organic Se from SY has higher bioavailability and deposition efficiency of Se in whole eggs as compared with inorganic Se from SS. The Se concentrations and Se deposition efficiency in the eggs increased from hens fed a SS- or SY-supplemented diet but decreased from hens fed a basal diet with the extension of the experimental duration. The results indicate that the dietary Se supplementation from SY should be limited to a maximum of 0.1 mg Se/kg complete feed when the eggs and meat produced from hens fed a SY-supplemented diet are used as food for humans directly, whereas up to 0.4 mg/kg organic Se from SY can be used to supplement the diets for laying hens when the products are used as raw materials for producing Se-enriched food.

Abstract
Objective: To investigate the effects of microRNA-451 on proliferation, invasion and migration of multiple myeloma RPMI-8226 cells and its mechanism. Methods: RPMI-8226 cells cultured in vitro were divided into blank control group (untransfected), negative control (NC) group and miR-451 mimic transfected (miR-451) group. The expression of miR-451 was detected by real-time quantitative PCR (qRT-PCR), cell proliferation was detected by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) array and clone formation experiment, cell invasion and migration were detected by Transwell, and the expressions of c-Myc, MMP-2 and MMP-9 proteins were detected by western blot. The targeting relationship between miR-451 and c-Myc was detected by double luciferase reporter gene assay. Results: Compared to the blank control group, the expression level of miR-451 was increased (2.85±0.27 vs 1.02±0.06), while the cell survival rate [(47.28±3.15)% vs (93.65±6.52)%], cloning formation rate [(15.03±1.34)% vs (28.48±2.12)%], invasive cell number (86.65±5.58 vs 135.47±9.85), migrating cell number (106.36±6.48 vs 165.28±11.05) and the expression level of c-Myc(0.35±0.03 vs 0.66±0.05), MMP-2 (0.20±0.02 vs 0.48±0.03) and MMP-9 (0.28±0.03 vs 0.59±0.06) protein were significantly decreased in the miR-451 group (P<0.05). In the negative control group, the expression level of miR-451, cell viability, clone formation rate, invasive cell number, migrating cell number, c-Myc protein, MMP-2 protein and MMP-9 protein were 0.94±0.05, (95.16±5.04)%, (27.55±2.26)%, (128.96±8.32) and (158.65±8.76), 0.68±0.06, 0.51±0.03, 0.54±0.03, respectively. There were no significant differences between the blank control group and the NC group (P>0.05). Double luciferase reporter gene experiment confirmed that c-Myc was a potential target gene of miR-451. Conclusion: miR-451 can inhibit the proliferation, invasion and migration of RPMI-8226 cells by targeting c-Myc.

Abstract
AIM The present study examined the associations between night-time sleep duration, midday napping duration and bedtime, and fasting glucose levels, and whether or not such associations are dependent on gender and age. METHODS This study was a cross-sectional analysis of 172,901 adults aged≥40 years living in mainland China. Sleep duration was obtained by self-reports of bedtime at night, waking-up time the next morning and average napping duration at midday. Fasting plasma glucose (FPG)≥7.0mmol/L was defined as hyperglycaemia. Independent associations between night-time sleep duration, midday naptime duration and bedtime with hyperglycaemia were evaluated using regression models. RESULTS Compared with night-time sleep durations of 6-7.9h, both short (<6h) and long (≥8h) night-time sleep durations were significantly associated with an increased risk of hyperglycaemia in women [odds ratio (OR): 1.12, 95% confidence interval (CI): 1.01-1.29 and OR: 1.14, 95% CI: 1.08-1.21, respectively], and revealed a U-shaped distribution of risk in women and no significant association in men. Long midday nap durations (≥1h) were significantly but weakly associated with hyperglycaemia (OR: 1.04, 95% CI: 1.01-1.09) compared with no napping without interactions from gender or age, whereas the association between bedtime and fasting glucose levels did vary according to gender and age. CONCLUSION Night-time sleep duration, midday napping duration and bedtime were all independently associated with the risk of hyperglycaemia, and some of the associations between these sleep characteristics and hyperglycaemia were gender- and age-dependent.

Abstract
Background:WHO survey showed that the prevalence of anxiety and depression in Chinese population and Chinese patients with chronic diseases were between 3.1% - 4.2% and 3.1% - 7.3%, respectively. Ankylosing Spondylitis Disease Activity Score (ASDAS) and Hospital Anxiety and Depression Scale (HADS) are commonly used to evaluate AS patients’ disease activity and mental health. All those assessments were mainly performed by health professionals (HCPs) with paper questionnaire previously. SSDM is a novel smart disease management tool that allows patients to do self-assessments on ASDAS and HADS by mobile terminals.Objectives:To estimate the prevalence of anxiety and depression in Chinese patients with AS and to analyze the potential association between disease activity and mental health.Methods:Under the guidance and training by HCPs, AS patients downloaded SSDM and performed self-assessments bundle of ASDAS and HADS with SSDM. ASDAS<=1.3, 1.3-2.1, 2.1-3.5 and >3.5 are defined as inactive (IDA), moderate (MDA), high (HDA) and very high (VHDA) disease activity, respectively. ASDAS score <=1.3 represents inactive disease status and achievement of T2T. HADS score >=8 can be diagnosed with anxiety or depression.Results:From June 2016 to Jan 2020, 1,931 AS patients (1,118 male, 813 female) with a mean age of 34.09 ± 11.86 (12-82) years and the median disease duration of 2.61 years from 207 hospitals performed bundle self-assessments for 2,477 times in total. According to the HADS and ASDAS assessment results, the prevalence of anxiety and depression in all patients was 36.7% and 39.3% respectively, which was significantly higher than that in the WHO survey in Chinese population and chronic disease patients. The proportion of patients achieved and failed on T2T was 29% and 71%, respectively. The prevalence of anxiety (A) and depression (D) was 25% and 23% among T2T achievers; and 37% and 32% among T2T failures, respectively (pA<0.05, pD<0.05).According to ASDAS, in IDA, MDA, HDA and VHDA subgroups, the prevalence of anxiety and depression was 27%, 36%, 41%, 52% and 29%, 38%, 45%, 56%, respectively. The correlation coefficients of anxiety (A) and depression (D) with ASDAS were rA=0.9908 and rD=0.9964. It suggested that with the increase of disease activity, the proportion of AS patients with anxiety and depression increased significantly. (Figure 1)Figure 1.The prevalence of anxiety and depression according to ASDAS.Conclusion:The prevalence of anxiety and depression in AS patients was significantly higher than that in the WHO survey in Chinese population and chronic disease patients. Higher prevalence of anxiety and depression were associated with higher levels of disease activity. SSDM is an effective mobile interface to monitor and study entanglement of disease activity and mental health in AS patients, which build a foundation for proactive interventions in future.Acknowledgments:Smart system of disease management (SSDM) was developed by Shanghai Gothic Internet Technology Co., Ltd.Disclosure of Interests:None declared

Abstract
e16092 Background: It has been extremely challenging to identify suitable predictive or prognostic factors of anti-VEGF agents. Apatinib, a vascular endothelial growth factor receptor 2(VEGFR-2) inhibitor, showed promising efficacy in chemo-refractory metastatic colorectal cancer (mCRC) patients in a phase II trial. The aim of current study was to identify the potential predictive and prognostic factors of apatinib in this phase II trial. Methods: A total of 48 patients with mCRC who had failed from standard fluorouracil-containing chemotherapies were recruited in this prospective single-arm study. Apatinib at a 500mg dose was administered daily continuously. Clinical parameters, including patients background, biochemical parameters at baseline, tumor markers at baseline and day 28, and adverse events in initial 28 days were evaluated to identify predictive and prognostic factors. The median neutrophil/lymphocyte ratio (NLR) was adopted as a cutoff value to discriminate patients with low versus high NLR. Early tumor marker decrease was defined as an abnormal parameter with a decrease of > 10% by day 28. This study is registered with the Chinese Clinical Trial Registry, number ChiCTR1900020503. Results: Patients characteristics were not associated with differences in PFS and OS. Seven (14.6%) and 11 (22.9%) patients had initial normal CEA and CA19-9, respectively, and were excluded from the analysis of tumor markers. The median NLR were 4.1. In univariate analysis, low baseline NLR, early CA19-9 decrease, and the hand-foot syndrome (HFS) were associated with good progression-free survival (PFS) [NLR, HR 0.38 (95% CI 0.16–0.89), P = 0.027; CA19-9, HR 0.37 (95% CI 0.16-0.83), P = 0.016; HFS HR 0.23 (95% CI 0.08-0.68, P = 0.007); respectively]. Low baseline NLR and early CA19-9 decrease were also associated with good overall survival (OS) [NLR, HR 0.34 (95% CI 0.17–0.67), P = 0.002; CA19-9, HR 0.46 (95% CI 0.23-0.95), P = 0.035; respectively]. NLR and HFS retained a significant association with PFS [NLR, HR 0.36 (95% CI 0.15–0.84), P = 0.019; HFS, HR 0.25 (95% CI 0.08–0.77), P = 0.016; respectively] while only NLR retained a significant association with OS [NLR, HR 0.35 (95% CI 0.17–0.70), P = 0.019] in the multivariate analysis using the aforementioned factors. Conclusions: Clinical parameters including low baseline NLR, early CA19-9 decrease and HFS could be positive predictive factors of the efficacy of apatinib in mCRC. NLR could be the independent prognostic factor of OS in mCRC. Additional studies are warranted for further validation.

Abstract
Abstract
Background
Mental disorders are the leading cause of disabilities worldwide, with depression and anxiety among the most common ones, affecting up to 1/3 of the worldwide population at least once in their lifetime. In both preclinical models and clinical studies, gut microbiota has been associated with altered behavior and anxiety or depression, respectively.
Aims
To investigate 1) whether the microbial profiles of patients with generalized anxiety disorder (GAD) and major depression disorder (MDD) differ from those of healthy controls (HC), and 2) whether specific bacterial taxa associate with GAD or MDD.
Methods
118 patients with primary GAD (n=82, 83.3 % female) or MDD (n=36, 62.9 % female) and 99 matched HC (66.6 % female) were recruited through the Anxiety Treatment and Research Centre. Anxiety, depression and stress levels were assessed by DASS-21 questionnaire. Stool samples were collected anaerobically and analysed for 16S rRNA gene sequencing through Illumina technique. The data was divided in 4 groups: 1) mental health disorder (MHD) combining GAD and MDD, 2) GAD, 3) MDD, and 4) HC. The data was analyzed following the pipelines of dada2 and QIIME2. RandomForest plugin for QIIME2 was used to investigate predictive characteristics of MHD, GAD or MDD microbiota. SPSS software v.23 was used to perform Spearman correlations and logistic regressions between microbial taxa and clinical scores.
Results
The mean anxiety score was 16.2 (severe anxiety) for GAD patients and 9.8 (moderate anxiety) for MDD patients; the mean depression score was 19.2 (moderate depression) for MDD patients and 16.0 (moderate depression) for GAD patients, while healthy controls averaged only 1.5 (normal anxiety) and 1.7 (normal depression) for anxiety and depression, respectively. The microbiota profile of the MHD group was predictive of the patients’ disease state with an 83.3% accuracy. In particular, increased relative abundance of Bacteroides ovatus and Bacteroides spp. and decreased relative abundance of Dialister spp. (Veilonellaceae), Haemophilus parainfluenzae and Bifidobacterium adolescentis, were predictive of MHD. Neither the GAD or MDD group microbiota profiles alone were accurate in the prediction of the patients’ disease state. There was a positive correlation between the relative abundance of Bacteroides spp. and a negative correlation between the relative abundance of Clostridium sensu stricto spp. and Sutterella, and the clinical scores of combined MDH and HC groups.
Conclusions
Our data suggest that patients with mental health disorders have different microbiota profiles compared to healthy controls. We have identified specific bacterial signatures that will inform mechanistic studies in gnotobiotic mouse models to investigate further the role of microbiome in mental disorders.

Abstract
Abstract
Background
Increasing evidence suggests that gut microbiota play a key role in gastrointestinal (GI) tract function. We have previously shown that fecal microbiota transplantation diarrhea predominant IBS patients into germ-free mice induces faster GI transit, increased permeability and innate immune activation. However, it is unknown whether gut dysfunction is induced by microbiota from patients with chronic constipation.
Aims
Here, we investigated the role of the intestinal microbiota in the expression of severe slow transit constipation in a patient with previous C difficile infection and extensive antibiotic exposure.
Methods
Germ-free (GF) mice (14 weeks old) were gavaged with diluted fecal content from the patient with constipation (PA) or a sex and age-matched healthy control (HC). 12 weeks later, we assessed gut motility and GI transit using videofluoroscopy and a bead expulsion test.. We then investigated intestinal and colonic smooth muscle isometric contraction in vitro using electric field stimulation (EFS), and acetylcholine (Ach) release was assessed by superfusion using [3H] choline. Histological changes were evaluated by H&E and immunohistochemistry.
Results
Mice with PA microbiota had faster whole GI transit (score 18.9 ± 0.9 (N=9) than mice with HC microbiota (15.4 ± 1.0, N=10, p=0.032), with markers located mainly in the distal small bowel and cecum. However, bead expulsion from the colon was significantly longer in PA mice (420.8 s ± 124.6 s, N=9) than in HC mice (82.6 s ± 20.0 s, N=10, p=0.026). This delayed colonic transit was likely due to colonic retroperistalsis visualized videofluoroscopically by retrograde flow of barium in the right colon of PA mice. There was no difference between the two groups in small intestinal or colonic tissues in Ach release or contractility induced by carbachol or KCl,. EFS caused transient biphasic relaxation and contraction in small intestine and colon, with the colonic contraction being stronger in the PA group. Microscopic tissue analysis showed disruption of the interstitial cells of Cajal (ICC) network and increased lymphocyte infiltration in colonic mucosa and submucosa in PA mice.
Conclusions
These results indicate that the microbiota is a driver of delayed colonic transit in a patient whose constipation started following extensive antibiotic exposure for C. difficile infection. The observed dysmotility pattern was not due to lower muscle contractility but likely caused by immune mediated changes in the ICC network.

Abstract
Abstract
Background
Dysbiosis may be defined as a change in the microbial composition or function that results in altered host function. Defensins are antimicrobial peptides, are part of innate immunity, and are important in host defense and maintaining homeostasis. Dysbiosis is a putative mechanism underlying the expression of many functional GI disorders like Irritable Bowel Syndrome (IBS) for which no biomarkers exist. Previous studies have revealed increased β-defensin (β-Def) levels in IBS patients, most likely due to changes in the microbiota.
Aims
We examined the hypotheses that: 1) Changes in β-Def are dependent on the manner in which dysbiosis is induced, and that 2) the direction of the change in β-Def depends on how dysbiosis was induced.
Methods
We used 4 models of experimentally induced dysbiosis to determine changes in fecal β-Def and to characterize the microbiota composition before and during the induction of dysbiosis. We used: 1) an antimicrobial cocktail (AC) in water; 2) a high-fat/ high-sugar diet (HFHSD); 3) a high salt diet (HSD) that we previously showed to induce a pro-inflammatory microbiota; and 4) mild restraint stress (MRS). All studies were performed in C57/BL6 mice except studies using MRS that were performed in NIH Swiss mice. In the AC or dietary studies, we employed a one-week intervention preceded by one-week baseline and recovery periods. In MRS studies, mice comparisons were made between a control and a stressed group. Stool samples were collected every 24 hours and were assayed for fecal β-Def levels analysis by an ELISA and microbial composition by 16S gene profiling.
Results
Exposure to AC or dietary change, but not MRS, resulted in significant decreases in fecal β-Def. Additionally, bacterial composition and diversity profiles were different in all mice except MRS mice (control vs. MRS males: p=0.414; control vs. MRS females: p=0.96). In contrast, mice exposed to the HSD revealed a significant increase in β-Def during treatment compared to baseline in both males (p=0.025) and females (p= 0.0019). The AC mice showed the largest changes and significant correlations between changes in β-Def levels and bacterial diversity (males: p=0.013, r=0.6; females: p=0.007, r=0.6) and richness (males: p=0.0008, r=0.70; females: p=0.003, r=0.62). However, no significant correlations were found between specific bacteria and β-Def levels in the HFHSD group.
Conclusions
We conclude that directional changes in fecal β-Def levels are dependent on the manner in which dysbiosis is induced. The use of β-Def as a biomarker requires comparisons with baseline levels obtained during remission in order to identify dysbiosis presence in microbiota-associated chronic GI conditions like IBS. Such an approach will identify patient subgroups that may benefit from microbiota-directed therapies.

Abstract
Abstract
Background
Irritable bowel syndrome (IBS) is one of the most common conditions seen by gastroenterologists for which there is no effective cure. The pathophysiology of IBS is multifactorial and poorly understood, but the condition is characterized by chronic abdominal pain accompanied by altered bowel habits in the absence of an underlying structural abnormality. IBS is frequently associated with psychiatric co-morbidities such as anxiety and depression and has been considered a disorder of gut-brain communication. We previously developed a humanized mouse model of IBS with co-morbid anxiety (IBS+A) by colonizing germ-free mice with fecal microbiota of IBS+A patients.
Aims
To test the therapeutic potential of the probiotic yeast Saccharomyces boulardii CNCM I-745 (S. bou) in preventing the transfer of the IBS+A phenotype and investigated underlying mechanisms.
Methods
Germ-free Swiss-Webster mice were colonized with fecal microbiota from an IBS+A patient or from a healthy subject (controls) and after three weeks they were gavaged daily for two weeks with 3g/kg/day of the probiotic S. bou (Biocodex–France) or water. Behavior, intestinal motility and permeability were assessed at sacrifice. Potential mechanisms were assessed by microbiota 16S rRNA gene sequencing, gene expression by Nanostring Counter Gene Expression and indole quantification by absorption using Kovak’s reagent.
Results
IBS+A colonized mice developed 25% faster gastrointestinal transit (P<0.05) and had a 3-fold longer latency time in the step-down test (P<0.001), indicative of anxiety-like behaviour compared with controls. S. bou normalized gastrointestinal transit (P<0.05) and shortened by 50% the step-down latency (P<0.01), compared to water-treated mice. Microbiota of IBS+A colonized mice had higher abundance of Unc. Erysipelotrichaceae and Unc. Coriobacteriaceae, and lower abundance of Oscillospira, Weissela, and Fructubacillus. S. bou treatment prevented these changes and the microbiota was similar to controls. Predicted function analysis in S. bou treated mice suggested higher number of genes implicated in indole biosynthesis (P<0.05) and S. bou increased indole levels by 20% in vitro. Finally, Trpv1, a gene implicated in visceral hypersensitivity and anxiety, was increased by 2-fold in IBS+A colonized mice compared with controls (P<0.001), and this was reverted by 20% (P<0.05) by S. bou treatment.
Conclusions
Our data indicate that Saccharomyces boulardii CNCM I-745 supplementation improves the intestinal and behavioral phonotype that is induced by IBS+A microbiota in mice. Putative mechanisms include regulation of indole production by bacteria and regulation of host Trpv1 gene expression. The results prompt investigation of S. bou in IBS patients with co-morbid anxiety.

Abstract
Abstract
Background
Abdominal pain is a common complaint in patients with chronic gastrointestinal disorders. Its treatment is of limited efficacy as the pathophysiology is largely unknown. Accumulating evidence suggests that gut microbiota is an important determinant of gut function, including visceral sensitivity. Germ-free (GF) mice have been shown to have altered pain signaling, which normalizes after colonization. Sex also appears to play a key role in visceral sensitivity, as abdominal pain is diagnosed predominantly in female patients. Thus, both gut bacteria and sex are important in the regulation of gut nociception, but the underlying mechanisms remain poorly understood.
Aims
To investigate the role of gut microbiota and sex in abdominal pain.
Methods
We used primary cultures of sensory neurons from dorsal root ganglia (DRG) of female and male conventional mice (SPF) or germ-free (GF) mice, age 7–18 weeks. To study the visceral afferent activity in vitro, calcium mobilization in DRG sensory neurons was measured by inverted fluorescence microscope using a fluorescent calcium probe Fluo-4 (1mM). Two parameters were considered: i) percentage of responding neurons and ii) intensity of neuronal response. First, DRG sensory neurons were stimulated by a TRPV1 agonist capsaicin (12.5nM, 125nM and 1.25µM) or by an agonist mix of G-protein coupled receptors (GPCR: bradykinin, histamine and serotonin; 1µM, 10µM and 100µM). We next cultured Escherichia coli JM83 (E. coli) and Enterobacter aerogenes (E. aer) overnight in LB and LDMIIG medium, respectively. Bacterial supernatant of 1010 CFU/mL was diluted to 1% in Krebs Ringer solution to treat DRG neurons from GF/SPF mice and calcium mobilization was measured.
Results
The percentage of neurons responding to capsaicin and GPCR agonist was similar in SPF male and SPF female. In contrast, the intensity of the neuronal response was higher in SPF male compared to SPF female mice in response to capsaicin (125nM p<0.035 and 1.25µM p<0.038) but not in response to GPCR. The same trend was observed in GF mice. Neuronal activation induced by capsaicin or GPCR agonist was similar in SPF and GF mice. While bacterial supernatant from E. coli did not affect the activity of sensory neurons, the bacterial supernatant from E. aer induced changes in calcium mobilization in DRG neurons.
Conclusions
Our data suggest that at the level of DRG neurons from healthy mice, female sex and the absence of gut microbiota do not predispose to visceral hypersensitivity. In fact, the intensity of neuronal responses to capsaicin appear to be higher in DRGs from male mice. Furthermore, we show that metabolites from certain bacteria can activate sensory neurons. Thus, further studies are needed to investigate the role of gut microbiota and sex in visceral sensitivity

Abstract
AIMS Although comammox have been discovered in a variety of ecosystems, there are few studies in urban lakes. This paper attempted to confirm whether this ammonia-oxidizing microbe exists in urban lakes and to determine the factors influencing its existence. METHODS AND RESULTS This study investigated the diversity and abundance of comammox bacteria in sediments of a typical urban lake in China, and their ecological relationship with other ammonia-oxidizing micro-organisms. The phylogenetic analysis indicated that comammox clade A existed in the sediment of Lake Donghu, and the comammox bacteria co-existed with ammonia-oxidizing archaea (AOA), ammonia-oxidizing bacteria (AOB) and anaerobic ammonia-oxidizing (anammox) bacteria in the sediment of this lake. The abundances of the ammonia monooxygenase subunit A (amoA) genes for comammox, AOA, AOB and anammox 16S rRNA were 2·43 × 108 , 1·07 × 108 , 3·24 × 107 and 3·21 × 1011 copies per gram dry sediment respectively. Moreover, the amoA gene abundance of comammox was positively correlated with that of AOA and AOB. The redundancy analysis showed that the abundance of the comammox amoA gene was negatively correlated with the concentration of main indicators for nitrogen status in both the sediment and the water column, indicating that eutrophication may inhibit the growth of comammox bacteria. CONCLUSIONS Comammox bacteria play an important ecological role in the nitrogen cycle of urban lake sediments. SIGNIFICANCE AND IMPACT OF THE STUDY Our results indicated comammox bacteria were widespread in urban lakes and eutrophication may inhibit their growth.
