Abstract
Animal nutritionists continue to investigate new strategies to combat the challenge of methane emissions from ruminants. Medicinal plants (MPs) are known to be beneficial to animal health and exert functional roles in livestock due to their phytogenic compounds with antimicrobial, immunostimulatory, antioxidative, and anti-inflammatory activities. Some MP has been reported to be anti-methanogenic and can effectively lower ruminants' enteric methane emissions. This review overviews trends in MP utilization in ruminants, their bioactivity and their effectiveness in lowering enteric methane production. It highlights the MP regulatory mechanism and the gaps that must be critically addressed to improve its efficacy. MP could reduce enteric methane production by up to 8-50% by regulating the rumen fermentation pathway, directing hydrogen toward propionogenesis, and modifying rumen diversity, structure, and population of the methanogens and protozoa. Yet, factors such as palatability, extraction techniques, and economic implications must be further considered to exploit their potential fully.

Abstract
Three new furano-lactones, asperilactones A-C (1-3), and two known compounds silvaticol (4) and violaceic acid (5) were isolated from an ethanol extract of Aspergillus nidulans, a fungus isolated from the Annelida Whitmania pigra Whitman (Haemopidae). Their structures were elucidated by a combination of spectroscopy, ECD calculations, comparing optical rotation values, and single-crystal X-ray diffraction analyses. Asperilactone A (1) represented the first example of furano-lactone with an unusual 2-thia-6-oxabicyclo[3.3.0]octane ring system. Asperilactones A and B showed weak toxicity against the HL-60 and RKO.

Abstract
OBJECTIVE The semaphorins are membrane or secreted proteins first identified in neural development. Semaphorin 4D (Sema4D) is the first family member found to have immune properties. We evaluated the potential of Sema4D as a marker for rheumatoid arthritis (RA) disease activity, singly and in combination with other known biomarkers including rheumatoid factor (RF) and C-reactive protein (CRP). METHODS Three hundred and eleven RA patients were enrolled. The patients were divided into three groups based on their disease activity in 28 joints (DAS28): mild, moderate, and severe. The healthy group included 40 healthy individuals. SerumSema4D was measured by quantitative ELISA and the specificity and sensitivity of biomarkers were evaluated by generating a receiver operating characteristic (ROC) curve to analyze their diagnostic accuracy. RESULTS Serum Sema4D levels in the moderate and severe RA groups were elevated significantly above those of the controls (P < 0.01), while levels in the mild RA and control groups did not differ significantly (P > 0.05). The Sema4D cutoff threshold was 15.7 ng/ml when the DAS28 was applied as a reference. Compared to the erythrocyte sedimentation rate (ESR and CRP, Sema4D had the highest specificity (96.8%) and area under the curve (0.80) for diagnosing RA activity. The highest specificity (100%) for the biomarker combinations was obtained when Sema4D was combined with CRP and anti-CCP, the combination of the Sema4D combined with ESR and anti-CCP had the highest sensitivity (99.35%). According to this result, a new model for jointly calculating RA activity of Sema4D,anti-CCP and CRP was constructed. Meanwhile another model is established by using the method of multivariate analysis.Model comparison results showed the the multiple regression algorithm method fitted the patients' disease activity better. CONCLUSION The serum Sema 4D level effectively reflects moderate to severe RA activity. Sema4D levels can be used together with conventional RA biomarkers to increase the diagnostic power of RA activity. The multiple regression algorithm method is promising in disease activity calculation.

Abstract
OBJECTIVE To compare the efficiency of multiple etiological techniques for detection of Schistosoma japonicum infections in wild mice, so as to provide technical supports to assessment of schistosomiasis transmission risk. METHODS Wild mice were captured with baited traps at night in Oncomelania hupensis snail-infested settings in schistosomiasis-endemic foci of Anhui Province from October to November, 2022. S. japonicum infections were detected in wild mice using microscopy of mouse liver tissues, microscopy of mouse mesenteric tissues, microscopy of mouse liver tissue homogenates, miracidial hatching test of mouse liver tissue homogenates, Kato-Katz technique and miracidial hatching test of mouse stool samples alone and in combinations. Identification of S. japonicum eggs or miracidia by any of these six assays was defined as an infection. The sensitivity of six assays alone or in combinations was compared for detection of S. japonicum infections in wild mice. RESULTS A total of 1 703 wild mice were captured, with 366 wild mice detected positive for S. japonicum (21.49%). There were significant differences in the prevalence of S. japonicum infections in wild mice by six assays (Q = 529.33, P < 0.001) and in the sensitivity of six assays for detection of S. japonicum infections in wild mice (χ2 = 527.78, P < 0.001). In addition, the combination of microscopy of mouse liver tissues and mesenteric tissues, combination of microscopy of mouse liver tissues and liver tissue homogenates and combination of microscopy of mouse liver tissues, microscopy of mesenteric tissues, microscopy of liver tissue homogenates and Kato-Katz technique showed 86.61%, 87.16% and 97.27% sensitivities for detection of S. japonicum infections in wild mice, respectively. CONCLUSIONS Diverse etiological assays show various efficiencies for detection of S. japonicum infections in wild mice. Combination of microscopy of mouse liver tissues and microscopy of mesenteric tissues, and combination of microscopy of mouse liver tissues and microscopy of liver tissue homogenates are potential approaches for field detection of S. japonicum infections in wild mice.

Abstract
Removing excessively produced cytokines is of paramount significance in blood purification therapy for hypercytokinemia-associated diseases. In this study, we devised a conduit that is modified with nanobodies (Nb) and incorporates static mixers (Nb-SMC) to eliminate surplus cytokines from the bloodstream. The low-pressure-drop (LPD) static mixer, with each unit featuring two 90°-crossed blades, was strategically arranged in a tessellated pattern on the inner wall of the conduit to induce turbulent mixing effects during the flow of blood. This arrangement enhances mass transfer and molecular diffusion, thereby assisting in the identification and elimination of cytokines. By utilizing computational fluid dynamics (CFD) studies, the Nb-SMC was rationally designed and prepared, ensuring an optimal interval between two mixer units (H/G = 2.5). The resulting Nb-SMC exhibited a remarkable selective clearance of IL-17A, reaching up to 85 %. Additionally, the process of Nb immobilization could be adjusted to achieve the simultaneous removal of multiple cytokines from the bloodstream. Notably, our Nb-SMC displayed good blood compatibility without potential adverse effects on the composition of human blood. As the sole documented static mixer-integrated conduit capable of selectively eliminating cytokines at their physiological concentrations, it holds promise in the clinical potential for hypercytokinemia in high-risk patients. STATEMENT OF SIGNIFICANCE: High-efficient cytokines removal in critical care still remains a challenge. The conduit technique we proposed here is a brand-new strategy for cytokines removal in blood purification therapy. On the one hand, nanobody endows the conduit with specific recognition of cytokine, on the other hand, the build-in static mixer enhances the diffusion of antigenic cytokine to the ligand. The combination of these two has jointly achieved the efficient and specific removal of cytokine. This innovative material is the only reported artificial biomaterial capable of selectively eliminating multiple cytokines under conditions close to clinical practice. It has the potential to improve outcomes for patients with hypercytokinemia and reduce the risk of adverse events associated with current treatment modalities.

Abstract
BACKGROUND Gender disparity in authorship broadly persists in medical literature, little is known about female authorship within pulmonary medicine. METHODS A bibliometric analysis of publications from 2012 to 2021 in 12 journals with the highest impact in pulmonary medicine was conducted. Only original research and review articles were included. Names of the first and last authors were extracted and their genders were identified using the Gender-API web. Female authorship was described by overall distribution and distribution by country/region/continent and journal. We compared the article citations by gender combinations, evaluated the trend in female authorship, and forecasted when parity for first and last authorship would be reached. We also conducted a systematic review of female authorship in clinical medicine. RESULTS 14,875 articles were included, and the overall percentage of female first authors was higher than last authors (37.0% vs 22.2%, p<0.001). Asia had the lowest percentage of female first (27.6%) and last (15.2%) authors. The percentages of female first and last authors increased slightly over time, except for a rapid increase in the COVID-19 pandemic periods. Parity was predicted in 2046 for the first authors and 2059 for the last authors. Articles with male authors were cited more than articles with female authors. However, male-male collaborations significantly decreased, whereas female-female collaborations significantly increased. CONCLUSIONS Despite the slow improvement in female authorship over the past decade, there is still a substantial gender disparity in female first and last authorship in high-impact medical journals in pulmonary medicine.

Abstract
At present, vanadium-based cathodes for aqueous zinc-ion batteries (AZIBs) are limited by their slow reaction kinetics, poor electrical conductivity, and low capacity retention. To overcome these problems, here, we design a layered porous Mn0.18V2O5@C as the cathode material for AZIBs using a manganese-containing metal-organic framework as a template through a simple solvothermal method. Such an electrode delivers an excellent specific capacity (380 mA h g-1 at 0.1 A g-1) accompanied by superior cycling stability (about 85% capacity retention for 2000 cycles at 6 A g-1). The excellent electrochemical performance of Mn0.18V2O5@C is ascribed to the improved interface activity including smooth zinc ion transport, abundant ion reaction active sites and accelerated charge transfer resulting from the coordination of the porous structure, doped conductive carbon, and the stable channel structure derived from the pillar effect of doping manganese ions, preventing a premature collapse of the electrode structure. It is also revealed by structural evolution analysis that the residual zinc ions also combine with the original Mn0.18V2O5 to form a ZnxMnyV2O5 phase, which serves as an additional structural pillar and in the meantime, also participates in the following cycles. These favorable electrochemical results suggest that Mn0.18V2O5@C is a suitable cathode material for AZIBs.

Abstract
Nine new ergosteroids (1-9) and seven known ones (10-16) were isolated from Talaromyces adpressus. Their structures and absolute configurations were determined by the interpretation of NMR spectroscopic data, HRESIMS, ECD calculations, and single-crystal X-ray diffraction analyses. Structurally, compound 1 was an ergosteroid with two epoxy and a 3α-OH group at ring A, while compounds 8 and 9 had a contracted ring A with a peroxy bridge between C-3 and C-9, which were reported for the first time. Compounds 2-6, 9, 11, and 15 displayed cytotoxic activities with IC50 values ranging from 0.4 to 32 μM, and compound 7 exhibited an immunosuppressive effect against LPS-induced B lymphocyte proliferation with an IC50 value of 8.6 μM. The structure-activity relationships of these compounds are briefly discussed.

Abstract
Objective Although Leflunomide (LEF) is effective in treating rheumatoid arthritis (RA), there are still a considerable number of patients who respond poorly to LEF treatment. Till date, few LEF efficacy-predicting biomarkers have been identified. Herein, we explored and developed a DNA methylation-based predictive model for LEF-treated RA patient prognosis. Methods Two hundred forty-five RA patients were prospectively enrolled from four participating study centers. A whole-genome DNA methylation profiling was conducted to identify LEF-related response signatures via comparison of 40 samples using Illumina 850k methylation arrays. Furthermore, differentially methylated positions (DMPs) were validated in the 245 RA patients using a targeted bisulfite sequencing assay. Lastly, prognostic models were developed, which included clinical characteristics and DMPs scores, for the prediction of LEF treatment response using machine learning algorithms. Results We recognized a seven-DMP signature consisting of cg17330251, cg19814518, cg20124410, cg21109666, cg22572476, cg23403192, and cg24432675, which was effective in predicting RA patient's LEF response status. In the five machine learning algorithms, the support vector machine (SVM) algorithm provided the best predictive model, with the largest discriminative ability, accuracy, and stability. Lastly, the AUC of the complex model(the 7-DMP scores with the lymphocyte and the diagnostic age) was higher than the simple model (the seven-DMP signature, AUC:0.74 vs 0.73 in the test set). Conclusion In conclusion, we constructed a prognostic model integrating a 7-DMP scores with the clinical patient profile to predict responses to LEF treatment. Our model will be able to effectively guide clinicians in determining whether a patient is LEF treatment sensitive or not.

Abstract
Signal regulatory protein (SIRPα) is an immune inhibitory receptor expressed by myeloid cells to inhibit immune cell phagocytosis, migration, and activation. Despite the progress of SIRPα and CD47 antagonist antibodies to promote anti-cancer immunity, it is not yet known whether SIRPα receptor agonism could restrain excessive autoimmune tissue inflammation. Here, we report that neutrophil- and monocyte-associated genes including SIRPA are increased in inflamed tissue biopsies from patients with rheumatoid arthritis and inflammatory bowel diseases, and elevated SIRPA is associated with treatment-refractory ulcerative colitis. We next identify an agonistic anti-SIRPα antibody that exhibits potent anti-inflammatory effects in reducing neutrophil and monocyte chemotaxis and tissue infiltration. In preclinical models of arthritis and colitis, anti-SIRPα agonistic antibody ameliorates autoimmune joint inflammation and inflammatory colitis by reducing neutrophils and monocytes in tissues. Our work provides a proof of concept for SIRPα receptor agonism for suppressing excessive innate immune activation and chronic inflammatory disease treatment.

Abstract
Enterovirus A71 (EV-A71)-related hand, foot, and mouth disease (HFMD) imposes a substantial clinical burden in the Asia Pacific region. To inform policy on the introduction of the EV-A71 vaccine into the National Immunization Programme, we investigated the seroepidemiological characteristics of EV-A71 in two prospective cohorts of children in southern China conducted between 2013 and 2018. Our results show that maternal antibody titres declined rapidly in neonates, with over half becoming susceptible to EV-A71 at 1 month of age. Between 6 months and 2 years of age, over 80% of study participants were susceptible, while one third remained susceptible at 5 years old. The highest incidence of EV-A71 infections was observed in children aged 5-6 months. Our findings support EV-A71 vaccination before 6 months for birth cohorts in southern China, potentially with a one-time catch-up vaccination for children 6 months-5 years old. More regionally representative longitudinal seroepidemiological studies are needed to further validate these findings.

Abstract
BACKGROUND A major hand-foot-and-mouth disease (HFMD) pathogen, coxsackievirus A16 (CVA16), has predominated in several of the last 10 years and caused the largest number of HFMD outbreaks between 2011 and 2018 in China. We evaluated the efficacy of maternal anti-CVA16 antibody transfer via the placenta and explored the dynamics of maternal and natural infection-induced neutralizing antibodies in children. METHODS Two population-based longitudinal cohorts in southern China were studied during 2013-2018. Participants were enrolled in autumn 2013, including 2475 children aged 1-9 years old and 1066 mother-neonate pairs, and followed for 3 years. Blood/cord samples were collected for CVA16-neutralizing antibody detection. The maternal antibody transfer efficacy, age-specific seroprevalence, geometric mean titre (GMT) and immune response kinetics were estimated. RESULTS The average maternal antibody transfer ratio was 0.88 (95% CI 0.80-0.96). Transferred maternal antibody levels declined rapidly (half-life: 2.0 months, 95% CI 1.9-2.2 months). The GMT decayed below the positive threshold (8) by 1.5 months of age. Due to natural infections, it increased above 8 after 1.4 years and reached 32 by 5 years of age, thereafter dropping slightly. Although the average duration of maternal antibody-mediated protection was < 3 months, the duration extended to 6 months on average for mothers with titres ≥ 64. CONCLUSIONS Anti-CVA16 maternal antibodies are efficiently transferred to neonates, but their levels decline quickly. Children aged 0-5 years are the main susceptible population and should be protected by CVA16 vaccination, with the optimal vaccination time between 1.5 months and 1 year of age.

Abstract
OBJECTIVE To investigate the changing trends in the prevalence of schistosomiasis in Anhui Province from 2004 to 2020, so as to provide the evidence for formulating the schistosomiasis elimination strategy in the province. METHODS The epidemiological data of schistosomiasis in Anhui Province from 2004 to 2020 were collected, and the trends in the endemic status of schistosomiasis were analyzed using a Joinpoint regression model. The trends in the prevalence of Schistosoma japonicum infections in humans, bovines and Oncomelania hupensis were measured in Anhui Province from 2004 to 2020 using average annual percent change (AAPC), and the correlations among the changing trends in the prevalence of S. japonicum infections in humans, bovines and O. hupensis snail status were evaluated using Pearson correlation analysis. RESULTS The prevalence of S.japonicum human infections continued to decline in Anhui Province from 2004 to 2020, with an annual mean decline of 14.8% [AAPC = -14.8%, 95% confidential interval (CI): (-18.9%, -10.5%), P < 0.01]. The prevalence of S. japonicum infections continued to decline in bovines in Anhui Province from 2004 to 2015 [AAPC = -31.3%, 95%CI: (-35.1%, -27.2%), P < 0.01], and was 0 for 5 successive years from 2016 to 2020. During the period from 2004 to 2020, there was an annual mean decline of 0.7% in areas of snail habitats [AAPC = -0.7%, 95%CI: (-1.2%, 0.3%), P < 0.05] and an annual mean decline of 9.2% in the density of living snails [AAPC = -9.2%, 95%CI: (-18.3%, 1.0%), P = 0.08] in Anhui Province from 2004 to 2020, and an annual mean decline of 35.6% was found in the density of S. japonicum-infected snails [AAPC = -35.6%, 95%CI: (-49.2%, -18.3%), P < 0.01] from 2004 to 2012, with no infected snails detected in Anhui Province from 2013 to 2020. There were significant correlations in the prevalence of S. japonicum infections between humans and bovines (r = 0.959, P < 0.01), between the prevalence of S. japonicum human infections and the density of S. japonicum-infected snails (r = 0.823, P < 0.01) and between the prevalence of S. japonicum infections in bovines and the density of S. japonicum-infected snails (r = 0.902, P < 0.01). CONCLUSIONS The prevalence of S. japonicum infections appeared a decline in humans, bovines and O. hupensis in Anhui Province from 2004 to 2020, and significant correlations were found among the changing trends in the prevalence of S. japonicum human infections, the prevalence of S. japonicum bovine infections and the density of S. japonicum-infected O. hupensis snails. Because of a minor decline in the area of snail habitats and widespread distribution of O. hupensis, however, there is still a risk of schistosomiasis transmission, and precision control for schistosomiasis remains to be reinforced in Anhui Province.

Abstract
OBJECTIVE To investigate the prevalence of Schistosoma japonicum infection in wild mice in Shitai County, Anhui Province, so as to provide insights into precise control of the source of S. japonicum infections. METHODS Wild mice were captured using the trapping method for three successive nights at snail-infested settings from Jitan Village of Jitan Township, and Shiquan Village and Xibai Village of Dingxiang Township, Shitai County, Anhui Province in June and October, 2018. All trapped wild mice were sacrificed and liver and mesenteric vein specimens were collected for detection of S. japonicum eggs using microscopy, while the fecal samples in mouse intestines were collected for identification of S. japonicum infections using Kato-Katz technique. In addition, the population density of trapped wild mice was estimated and the prevalence of S. japonicum infection was calculated in trapped wild mice. RESULTS A total of 376 wild mice were trapped from three villages in Shitai County. The population density of trapped wild mice was 9.1% (376/4 124), and the prevalence of S. japonicum infection was 24.2% (91/376) in trapped wild mice. The highest prevalence of S. japonicum infection was detected in Shiquan Village of Dingxiang Township (30.1%), and the lowest prevalence was seen in Xibai Village of Dingxiang Township; however, there was no significant difference in the prevalence of S. japonicum infection in trapped wild mice among three villages (χ2= 4.111, P > 0.05). In addition, there was no significant difference in the prevalence of S. japonicum infection in wild mice captured between on June (26.8%, 34/127) and October (22.9%, 57/249) (χ2 = 0.690, P = 0.406). The trapped wild mice included 6 species, including Rattus norvegicus, Niviventer niviventer, R. losea, Apodemus agrarius, Mus musculus and N. coning, and the two highest prevalence of S. japonicum infection was detected in R. losea (34.9%, 22/63) and R. norvegicus (31.2%, 44/141). CONCLUSIONS The prevalence of S. japonicum infections is high in wild mice in Shitai County, and there is a natural focus of schistosomiasis transmission in Shitai County.

Abstract
Anti-integrins are therapeutically effective for inflammatory bowel disease, yet the relative contribution of α4β7 and αEβ7 to gut lymphocyte trafficking is not fully elucidated. Here, we evaluate the effect of α4β7 and αEβ7 blockade using a combination of murine models of gut trafficking and longitudinal gene expression analysis in etrolizumab-treated patients with Crohn's disease (CD). Dual blockade of α4β7 and αEβ7 reduces CD8+ T cell accumulation in the gut to a greater extent than blockade of either integrin alone. Anti-αEβ7 reduces epithelial:T cell interactions and promotes egress of activated T cells from the mucosa into lymphatics. Inflammatory gene expression is greater in human intestinal αEβ7+ T cells. Etrolizumab-treated patients with CD display a treatment-specific reduction in inflammatory and cytotoxic intraepithelial lymphocytes (IEL) genes. Concurrent blockade of α4β7 and αEβ7 promotes reduction of cytotoxic IELs and inflammatory T cells in the gut mucosa through a stepwise inhibition of intestinal tissue entry and retention.

Abstract
Nuclear factor erythroid 2-related factor 2 (NRF2) is aberrantly activated in about 93% of pancreatic cancers. Activated NRF2 regulates multiple downstream molecules involved in cancer cell metabolic reprogramming, translational control, and treatment resistance; however, targeting NRF2 for pancreatic cancer therapy remains largely unexplored. In this study, we used the online computational tool CellMinerTM to explore the NCI-60 drug databases for compounds with anticancer activities correlating most closely with the mRNA expression of NQO1, a marker for NRF2 pathway activity. Among the >100,000 compounds analyzed, NSC84167, termed herein as NRF2 synthetic lethality compound-01 (NSLC01), was one of the top hits (r = 0.71, P < 0.001) and selected for functional characterization. NSLC01 selectively inhibited the viabilities of four out of seven conventional pancreatic cancer cell lines and induced dramatic apoptosis in the cells with high NRF2 activation. The selective anticancer activity of NSLC01 was further validated with a panel of nine low-passage pancreatic patient-derived cell lines, and a significant reverse correlation between log(IC50) of NSLC01 and NQO1 expression was confirmed (r = -0.5563, P = 0.024). Notably, screening of a panel of nine patient-derived xenografts (PDXs) revealed six PDXs with high NQO1/NRF2 activation, and NSLC01 dramatically inhibited the viabilities and induced apoptosis in ex vivo cultures of PDX tumors. Consistent with the ex vivo results, NSLC01 inhibited the tumor growth of two NRF2-activated PDX models in vivo (P < 0.01, n = 7-8) but had no effects on the NRF2-low counterpart. To characterize the mechanism of action, we employed a metabolomic isotope tracer assay that demonstrated that NSLC01-mediated inhibition of de novo synthesis of multiple amino acids, including asparagine and methionine. Importantly, we further found that NSLC01 suppresses the eEF2K/eEF2 translation elongation cascade and protein translation of asparagine synthetase. In summary, this study identified a novel compound that selectively targets protein translation and induces synthetic lethal effects in NRF2-activated pancreatic cancers.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) tumors are characterized by a desmoplastic reaction resulting in dense deposition of collagen that is known to promote cancer progression. A central mediator of pro-tumorigenic collagen signaling is the receptor tyrosine kinase discoid domain receptor 1 (DDR1). DDR1 is a critical driver of a mesenchymal and invasive cancer cell PDAC phenotype. Previous studies have demonstrated that genetic or pharmacologic inhibition of DDR1 reduces PDAC tumorigenesis and metastasis. Here, we investigated whether DDR1 signaling has cancer cell non-autonomous effects that promote PDAC progression and metastasis. We demonstrate that collagen-induced DDR1 activation in cancer cells is a major stimulus for CXCL5 production, resulting in the recruitment of tumor-associated neutrophils (TANs), the formation of neutrophil extracellular traps (NETs) and subsequent cancer cell invasion and metastasis. Moreover, we have identified that collagen-induced CXCL5 production was mediated by a DDR1-PKCθ-SYK-NFkB signaling cascade. Together, these results highlight the critical contribution of collagen I-DDR1 interaction in the formation of an immune microenvironment that promotes PDAC metastasis.

Abstract
Abstract
Pancreatic ductal adenocarcinoma (PDAC) is almost uniformly fatal and characterized by early metastasis. Oncogenic KRAS mutations prevail in 95% of PDAC tumors and co-occur with genetic alterations in the TP53 tumor suppressor in nearly 70% of patients. Most p53 alterations are missense mutations that exhibit gain-of-function phenotypes that include increased invasiveness and metastasis. However, the extent of direct cooperation or synergism between KRAS effectors and mutant p53 remain undefined. To study how KRAS effectors and mutant p53 cooperate to drive PDAC development, we developed a novel somatic model that expresses mutant KRAS and p53 only in pancreas tumor cells, leaving the tumor microenvironment and immune system intact. PDAC genetically engineered mouse models (GEMMs) were generated by crossing a conditional oncogenic KRasG12D (K) allele with a conditional null p53 allele (Pfl) or a novel, conditional knock-in mutant p53R172H allele (Pwm) that selectively expresses mutant p53 in tumor cells while preserving wildtype p53 expression in all other animal cells. The incidence of metastatic lesions in the liver and lungs of KPwmC mice was over 2-fold greater (p=.03) relative to KPflC mice. Through orthogonal analyses of this model and human PDAC samples, we show that oncogenic KRAS effectors phosphorylate and activate cyclic AMP responsive element binding protein 1 (CREB1), allowing physical interactions with mutant p53 to transcriptionally upregulate the pro-metastatic transcription factor, FOXA1, which enhances β-catenin stabilization and activity. Targeting KRAS and mutant p53 cooperativity through pharmacologic inhibition of CREB1 dramatically dampens FOXA1 expression and PDAC metastasis. Our findings demonstrate a direct, mechanistic link between key oncogenic KRAS signaling elements and mutant p53 that result in a broad, multiplexed activation of cancer-associated transcriptional networks. Moreover, we identify CREB1 as a viable therapeutic strategy to undermine oncogenic KRAS and mutant p53 cooperation to mitigate PDAC metastasis.

Abstract
Abstract
Introduction: Pancreatic ductal adenocarcinoma (PDAC) is a systemic disease characterized by early metastasis involving numerous pro-metastatic pathways. However, dominant drivers of early PDAC cell dissemination and metastasis remain poorly defined. The non-canonical Wnt-PCP pathway has been shown to promote cancer cell motility predominantly through Wnt ligand-mediated activation of frizzled receptors that result in cytoskeleton rearrangements. As one of these Wnt ligands, Wnt11, has been previously implicated in metastasis, we tested if Wnt11 significantly affects PDAC metastasis in vivo.
Methods: LSL-KrasG12D/+, p53wmR172H/+, and p48-Cre alleles were crossed with and without a conditional Wnt11fl allele to generate cohorts of Wnt11 wildtype and knockout mice in the well-established KPC PDAC mouse model (KPwmC, n = 22; KPwmC-Wnt11fl/fl, n = 37). Both cohorts included mice with a conditional LSL-ROSA26-tdTomato reporter to identify and enumerate distant metastases. Mice were sacrificed when euthanasia criteria were met, and metastases were visualized via full organ fluorescence microscopy to identify tdTomato(+) signals. Liver and lung metastases were enumerated and measured through automated color range selection and manual counting. Metastases were classified by diameter as micrometastases (<100 uM), intermediate metastases (100-499 uM), or macrometastases (≥500 uM).
Results: Primary pancreatic tumors from KPwmC and KPwmC-Wnt11fl/fl mice were similar in histologic appearance without gross alterations in peritumoral stroma. There were no differences in median overall survival between KPwmC and KPwmC-Wnt11fl/fl mice (185 vs. 193 days, p = 0.92). Pulmonary micrometastatic disease in mice <170 days at euthanasia was significantly lower in KPwmC-Wnt11fl/fl mice relative to KPwmC mice (mean number of metastases 88.8 vs. 1780, respectively; p = 0.009). Moreover, while pulmonary metastases in KPwmC mice were diffuse and miliary, the lungs of KPwmC-Wnt11fl/fl mice contained only scant, scattered metastases. No significant differences were observed in the mean number of intermediate-sized (0.5 vs. 27.4, p = 0.17) or macrometastases (0.0 vs 1.6, p = 0.13). Differences in metastatic tumor size or burden were not observed in liver metastases between each cohort.
Conclusions: Wnt11 affects the pattern and latency of early metastasis to the lung but does not affect any stage of hepatic metastasis. The role of Wnt11 in PDAC metastasis is context dependent and may be related to factors inherent in the pre-metastatic niche.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is almost universally lethal. A critical unmet need exists to explore essential susceptibilities in PDAC and to identify druggable targets to improve PDAC treatment. KRAS mutations dominate the genetic landscape of PDAC and lead to activation of multiple downstream pathways and cellular processes. Here, we investigated the requirement of these pathways for tumor maintenance using an inducible KrasG12D -driven PDAC mouse model (iKras model), identifying that RAF-MEK-MAPK signaling is the major effector for oncogenic KRAS-mediated tumor maintenance. However, consistent with previous studies, MEK inhibition had minimal therapeutic effect as a single agent for PDAC in vitro and in vivo. Although MEK inhibition partially downregulated transcription of glycolysis genes, it failed to suppress glycolytic flux in PDAC cells, which is a major metabolic effector of oncogenic KRAS. Accordingly, an in vivo genetic screen identified multiple glycolysis genes as potential targets that may sensitize tumor cells to MEK inhibition. Inhibition of glucose metabolism with low-dose 2-deoxyglucose in combination with a MEK inhibitor induced apoptosis in KrasG12D -driven PDAC cells in vitro. The combination also inhibited xenograft PDAC tumor growth and prolonged overall survival in a genetically engineered PDAC mouse model. Molecular and metabolic analyses indicated that co-targeting glycolysis and MAPK signaling results in apoptosis via induction of lethal endoplasmic reticulum stress. Together, our work suggests that combined inhibition of glycolysis and the MAPK pathway may serve as an effective approach to target KRAS-driven PDAC. SIGNIFICANCE: This study demonstrates the critical role of glucose metabolism in resistance to MAPK inhibition in KRAS-driven pancreatic cancer, uncovering a potential therapeutic approach for treating this aggressive disease.

Abstract
Objective: To investigate the clinicopathological characteristics, differential diagnosis and prognosis of nodal nevi (NN). Methods: Eighteen cases of NN diagnosed at Fudan University Shanghai Cancer Center, Shanghai, China from 2009 to 2019 were collected. The clinicopathological characteristics and follow-up data were retrospectively analyzed. Histopathologic evaluation and immunohistochemical studies were carried out. The Vysis Melanoma FISH Probe Kit, combined with 9p21(CDKN2A) and 8q24(MYC) assays were performed in 2 cases. Results: There were 2 males and 16 females in the case series. The age of the patients ranged from 36 to 70 years (average 48.2 years). Fifteen cases located in axillary lymph nodes, 1 in inguinal lymph node, 1 in cervical lymph node, and 1 in external iliac lymph node. NN was found in only one lymph node in each case. Histologically, the nevus cell aggregates were found in capsule of lymph nodes in all cases. Nevus cells grew along the capsule into trabeculae in 8 cases, with 3 of them scattered in parenchyma. In one of these 8 cases, nevus cell aggregates massively occupied the parenchyma of the lymph node. The largest lesions in the 18 NN cases measured from 0.2 to 6.5 mm. All of the NN cases were classified as conventional nevi. The majority of the cases were composed of uniform nevus-like cells and identical to cutaneous pigmented nevi without atypia, necrosis, or mitosis. In the NN case that massively occupied parenchyma, some areas had abundant nevus cells and displayed atypical cytologic features, including increased nucleo-cytoplasmic ratio, small nucleoli, and occasional mitotic figures. Immunohistochemistry was performed in 13 cases. All of them were positive for S-100, SOX10, Melan A, and p16. HMB45 showed weak staining in rare cells of only one case out of 13 cases. Ki-67 labeling index <1% was found in all 13 cases. Additionally, the results of FISH assay were both negative. All patients were followed up for 13 to 129 months (median 31.5 months). Except that one patient died of the salivary gland carcinoma, the other patients all survived without tumor during the follow-up period. Conclusions: NN is a benign melanocytic lesion in lymph node. It is important to distinguish NN from metastatic melanoma when nevus cells occur in parenchyma and subcapsular sinus of lymph nodes, or show some atypical cytologic features. The morphology of bland nevus cells in capsule and trabeculae is a valuable clue. Besides, immunohistochemical profiling and FISH assay are helpful in the differential diagnosis.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is almost uniformly fatal and characterized by early metastasis. Oncogenic KRAS mutations prevail in 95% of PDAC tumors and co-occur with genetic alterations in the TP53 tumor suppressor in nearly 70% of patients. Most TP53 alterations are missense mutations that exhibit gain-of-function phenotypes that include increased invasiveness and metastasis, yet the extent of direct cooperation between KRAS effectors and mutant p53 remains largely undefined. We show that oncogenic KRAS effectors activate CREB1 to allow physical interactions with mutant p53 that hyperactivate multiple prometastatic transcriptional networks. Specifically, mutant p53 and CREB1 upregulate the prometastatic, pioneer transcription factor FOXA1, activating its transcriptional network while promoting WNT/β-catenin signaling, together driving PDAC metastasis. Pharmacologic CREB1 inhibition dramatically reduced FOXA1 and β-catenin expression and dampened PDAC metastasis, identifying a new therapeutic strategy to disrupt cooperation between oncogenic KRAS and mutant p53 to mitigate metastasis. SIGNIFICANCE: Oncogenic KRAS and mutant p53 are the most commonly mutated oncogene and tumor suppressor gene in human cancers, yet direct interactions between these genetic drivers remain undefined. We identified a cooperative node between oncogenic KRAS effectors and mutant p53 that can be therapeutically targeted to undermine cooperation and mitigate metastasis.This article is highlighted in the In This Issue feature, p. 1861.

Abstract
China has achieved high vaccination coverage under the Expanded Program on Immunization (EPI) in children 1-2 years of age. However, a knowledge gap exists regarding vaccination coverage and timeliness for children >2 years of age. As such, this study aimed to estimate coverage and timeliness for all EPI and selected non-EPI vaccines within a rural area of China. Immunization data for 5091 children, born between September 2003 and November 2015, were collected from vaccination cards obtained during sero-surveillance follow-up visits and/or from the Hunan immunization information system. For each dose of both EPI and non-EPI vaccines, vaccination coverage and timeliness were calculated, and temporal variations were examined across birth cohorts. We found coverage for EPI vaccines scheduled for <12 months was 97.1%-99.4%. However, for EPI vaccines scheduled at 6 years coverage was 44.4%-51.7%. The timeliness for EPI vaccines was generally poor, especially for EPI vaccines introduced after 2008 or scheduled for administration at ≥12 months, with a maximum of 35.4% of children vaccinated according to schedule. Despite this, we found increasing trends in vaccination coverage and improvements in timeliness for EPI vaccines. However, for non-EPI vaccines, we found only moderate increases, and in some cases decreases, in vaccination coverage. This study demonstrates the success and improvement of the Chinese immunization program, but also highlights some challenges to be addressed. We recommend that future changes in vaccine practice and policy should primarily focus on improving coverage and timeliness of vaccines introduced after 2008, and/or scheduled for administration ≥12 months.

Abstract
BACKGROUND Since 1997, epidemics of hand, foot, and mouth disease associated with enterovirus A71 (EV-A71) have affected children younger than 5 years in the Asia-Pacific region, including mainland China. EV-A71 vaccines have been licensed for use in children aged 6-71 months in China, but not for infants younger than 6 months. We aimed to assess the dynamics of maternal EV-A71 antibodies to inform choice of potential vaccination strategies to protect infants younger than 6 months, because they have a substantial burden of disease. METHODS We did a longitudinal cohort study with mother-neonate pairs in local hospitals in southern China during 2013-18. We collected cord blood from neonates and venous blood from mothers at delivery. We followed up and collected blood samples from the children at ages 2, 4, 6, 12, 24, and 36 months and tested for the presence of neutralising antibodies against EV-A71 with virus neutralisation assays. Seropositivity, or protective titre, was defined as a neutralisation antibody titre of 16 or higher. We estimated the seroprevalence, geometric mean titre (GMT), and transfer ratio of maternal antibodies. We used a binomial distribution to derive the 95% CIs of seroprevalence. Seropositivity between mothers and neonates was compared by use of an agreement (κ), while GMTs were compared by use of paired Student's t tests. FINDINGS Between Sept 20, 2013, and Oct 14, 2015, 1054 mothers with 1066 neonates were enrolled. The EV-A71 GMT was similar among pairs of neonates (22·7, 95% CI 20·8-24·9) and mothers (22·1, 95% CI 20·2-24·1; p=0·20). The mean transfer ratio of maternal antibodies was 1·03 (95% CI 0·98-1·08). Although 705 (66%) of 1066 neonates acquired protective concentrations of EV-A71 antibodies from mothers, these declined rapidly, with a half-life of 42 days (95% CI 40-44). The time to loss of protective immunity was extended to 5 months in neonates with mothers who had titres of 128 or higher. By age 30 months, 28% of children had become seropositive because of natural infection. INTERPRETATION EV-A71 maternal antibodies were efficiently transferred to neonates, but declined quickly to below the protective threshold, particularly among those whose mothers had low antibody titres. Our findings suggest that maternal vaccination could be explored to provide neonatal protection against EV-A71 through maternal antibodies. Catch-up vaccination between ages 6 months to 5 years could provide protection to the approximately 30-90% of children that have not had natural EV-A71 infection by that age.

Abstract
OBJECTIVE An increasing amount of evidence indicates that microRNAs (miRNAs) can be potential diagnostic and prognostic markers for various cancers. In this study, a novel miRNA, miR-1205, was identified in lung adenocarcinoma (LUAD). PATIENTS AND METHODS First, the expression of miR-1205 in tissues was determined and verified to be correlated with the prognosis of patients. Overexpression and knockdown in LUAD cells were chosen to evaluate the effect of miR-1205 on cell growth in vitro. Luciferase assays, Western blot and rescue assays were performed to screen and confirm potential targets of miR-1205. RESULTS We demonstrated that miR-1205 was down-regulated in the tissues of LUAD, and that miR-1205 may be a predictor of overall survival of LUAD. The overexpression of miR-1205 promoted cell proliferation and colony formation. Our results indicated that miR-1205 targeted APC2 directly, serving as a vital part in accelerating LUAD cell proliferation. CONCLUSIONS We showed that miR-1205 could promote LUAD cell growth by targeting APC2 protein expression and provided further proof of miR-1205 as a potential non-invasive biomarker and therapeutic target for LUAD.

Abstract
Abstract
Therapeutic approaches to treat inflammatory bowel diseases (IBD) include targeting integrins that mediate adhesion and migration of lymphocytes to the gastrointestinal (GI) tract. Etrolizumab is a humanized monoclonal antibody that selectively binds the β7 subunit of the heterodimeric integrins of α4β7 and αEβ7. The relative contribution of α4β7 and αEβ7 integrin family members to lymphocyte migration and retention in GI tractremains to be characterized. Here we applied single-cell technologies to healthy and IBD patient biopsies and found that αEβ7 is highly expressed in a subset of proinflammatory CD4+T cells and majority of cytotoxic intraepithelial CD8+T cells. In order to understand the role of αEβ7 in gut T cell accumulation, we used a photo-convertible reporter system to determine that concurrent inhibition of α4β7 and αEβ7 together led to a greater reduction of polyclonal or antigen specific T cell accumulation in the intestinal mucosa and epithelium compared to single blockade of either α4β7 or αEβ7. Further intra-vital two-photon microscopy and photo-specific labeling experiments revealed that blockade of αEβ7 reduces T cell interactions with basolateral epithelial surface, increases the migratory speed of activated T cells in the intestinal mucosa, and facilitates effector T cell egress from the intestinal mucosal through lymphatic vessels. Our data suggests co-blockade of α4β7 and αEβ7 together offers a superior inhibition of T cell accumulation in gastrointestinal tissues through a stepwise inhibition of T cell migration and subsequent tissue retention.

Abstract
Objective: The Chinese Anti-Cancer Association Genitourinary Cancer Committee Prostate Cancer Working Group released Consensus of prostate cancer (PCa) screening in 2017. This program aims to evaluate the methods and significance of prostate cancer precision screening in high risk population. Methods: A total of 2 159 eligible males enrolled from 13 community centers and 3 screening centers received PSA test from April 2017 to August 2018. Prostate-specific antigen (PSA) determination in serum with a cut-off of ≥4.0 ng/ml was the main screening test and indication for biopsy. The interviewer-administered questionnaire covered demographic characteristics and environmental exposure factors. The associations between these factors and prostate cancer risk were determined by multivariable unconditional logistic regression models. Results: Altogether, 271 cases (12.6%) had a confirmed PSA increase ≥ 4.0 μg/L (median 9.1, range 4.0-25.0). Subsequently, 57 subjects (21.0%) out of the 271 PSA-suspicious men underwent prostate biopsy, and 34 (59.6%) were confirmed as prostate cancer. Until now, the overall prostate cancer incidence in the first screening round was1.57%. There were no statistical differences in the distributions of PSA-suspicious and prostate cancer incidence between community centers and screening centers (P=0.578 and 0.735). Age (OR: 2.63; 95%CI: 1.84-3.75, P<0.001) and chronic prostatitis history (OR: 2.02; 95%CI: 1.55-2.63, P<0.001) were significantly associated with PSA level. After adjustment for these factors, older age (OR: 4.04; 95%CI: 1.71-9.59, P=0.002) and statins use (OR: 3.09; 95%CI: 1.25-7.69, P=0.015) were associated with an elevated risk of PCa. Conclusions: It is of substantial significance to screen prostate cancer in high risk population. Both community centers and screening centers methods are effective. Although largely underestimated, the incidence of PCa in the targeted Chinese population is higher than expected. Older men have a high risk of harboring PCa. Our study suggests a decreased risk of PCa in men with statins use. Prostate Cancer Precision Screening is promising to improve prostate cancer survival in China.

Abstract
OBJECTIVE miRNAs have been confirmed to be related to cell proliferation and apoptosis. In this study, we detected the potential effect of miR-448 on glioma cell proliferation and apoptosis. MATERIALS AND METHODS miR-448 and CTTN expression levels were detected in glioma cell lines with quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). Cells were transfected with miR-448 mimics and inhibitor by using lipofectamine 2000 respectively. The proliferative ability of transfected cells was detected via methyl thiazolyl tetrazolium (MTT) and cell counting kit-8 (CCK8) assays. Cell apoptosis and cell-cycle were tested using flow cytometry. The regulatory correlation between miR-448 and CTTN was explored by bioinformatics analysis and luciferase reporter assay. RESULTS Lower expression of miR-448 and higher level of CTTN were detected in glioma cells. MiR-448 could regulate cell proliferation, cell apoptosis, and cell cycle. CTTN was negatively regulated by miR-448. CONCLUSIONS miR-448 downregulates CTTN to inhibit cell proliferation and promote apoptosis in glioma, which indicates a potential therapeutic target of glioma.

Abstract
Background Hand, foot, and mouth disease (HFMD) represents a substantial disease burden in the Western Pacific region. We investigated the spectrum of causative enteroviruses of HFMD, and evaluated different clinical samples' diagnostic yield for enteroviruses. Methods We enrolled pediatric patients hospitalized for HFMD among 6 hospitals in Anhua County, Hunan Province, China between October 2013 and September 2016. Throat swabs and stool samples (or rectal swabs) were collected to detect the enterovirus serotypes by real-time reverse-transcription polymerase chain reaction (PCR) or nested PCR. Results Among the 2836 patients, only 1 developed severe illness. Seventeen serotypes were identified in 2401 patients (85%), with the most frequently detected being CV-A16 (29% [814]), CV-A6 (28% [784]), EV-A71 (17% [491]), CV-A10 (4% [114]), and CV-A4 (2% [53]). Children were younger in CV-A6, CV-A10, and CV-A4 infections (median, 12 months; interquartile range [IQR], 12-24 months) than EV-A71 and CV-A16 infections (median, 24 months; IQR, 12-36 months; P < .05). The predominant enterovirus serotype shifted between CV-A16 and CV-A6 during the 3 years. Stool had a higher diagnostic yield (89%) than rectal (77%) and throat swabs (74%). Detection rates reached 93% when testing stools followed by throat swabs if stools were negative, and 89% when testing rectal swabs followed by throat swabs if rectal swabs were negative. Conclusions Our results provide a virological benchmark for future surveillance and diagnostics. Continuous comprehensive virological surveillance is essential, especially after implementation of the EV-A71 vaccine in China, to monitor serotype replacement and the vaccine's impact.

Abstract
Despite advances in cancer therapeutics, pancreatic cancer remains difficult to treat and often develops resistance to chemotherapies. We have evaluated a bioavailable genistein analogue, AXP107-11 which has completed phase Ib clinical trial, as an approach to sensitize tumor cells to chemotherapy. Using organotypic cultures of 14 patient-derived xenografts (PDX) of pancreatic ductal adenocarcinoma, we found that addition of AXP107-11 indeed sensitized 57% of cases to gemcitabine treatment. Results were validated using PDX models in vivo. Further, RNA-Seq from responsive and unresponsive tumors proposed a 41-gene treatment-predictive signature. Functional and molecular assays were performed in cell lines and demonstrated that the effect was synergistic. Transcriptome analysis indicated activation of G-protein-coupled estrogen receptor (GPER1) as the main underlying mechanism of action, which was corroborated using GPER1-selective agonists and antagonists. GPER1 expression in pancreatic tumors was indicative of survival, and our study proposes that activation of GPER1 may constitute a new avenue for pancreatic cancer therapeutics.

Abstract
Objective: To study the operative method, special technique and curative effect of complete neuroendoscopic microvascular decompression(MVD) related to vertebrobasilar artery compression. Methods: Thirteen patients with functional cranial nerve disease caused by vertebrobasilar artery as direct or indirect responsible vessel accepted complete endoscopic MVD, including 11 patients with hemifacial spasm and 2 patients with trigeminal neuralgia. The procedure and curative effect of endoscopic surgery were analyzed retrospectively. Results: All procedures of complete neuroendoscopic MVD were successfully completed.Intraoperative observation by endoscope showed that 6 cases were oppressed directly by vertebral artery, 2 cases were oppressed directly by basilar artery, 5 cases were combined oppressed by displaced basilar artery and other vessels (1 case was superior cerebellar artery and 4 cases were anterior inferior cerebellar artery). During the operation, Teflon sheets was placed directly into the compression point in 2 cases, the "Pre-placed" technique was used to place Teflon sheets in 7 cases, and the "Set up bridge" technique was used to place Teflon sheets in 4 cases. Follow-up for 8-38 months,the symptoms disappeared completely in 12 cases and improved in 1 case. No deaths and severe complications occurred, such as postoperative bleeding, cerebellar infarction and intracranial infection. Conclusion: MVD related to vertebrobasilar artery compression can be performed by complete neuroendoscopic technique, which can achieve sufficient decompression effect and curative effect.Flexible use of the special technology of placing Teflon sheets by single-hand under endoscope, such as the "Pre-placed" and "Set up bridge" technique, is an important technical guarantee for the successful completion of endoscopic MVD.

Abstract
Objective: To investigate the short-term efficacy and adverse events of chemotherapy combined with androgen-deprivation therapy in high-volume metastatic hormone sensitive prostate cancer. Methods: From March 2015 to August 2017, 55 patients with high-volume metastatic hormone sensitive prostate cancer were enrolled at Department of Urology, Fudan University Shanghai Cancer Center receiving chemotherapy combined with androgen-deprivation therapy. The age was 65(8) years (M(Q(R))) (range: 46 to 79 years). Patients were enrolled in the study for continuous androgen-deprivation therapy (medical or surgical castration), combined with docetaxel 75 mg/m(2) intravenous injection on the first day, repeated every 21 days (6 cycles). Endpoints included overall survival, progression-free survival of prostate cancer, prostate specific antigen (PSA) response rate, and adverse events. Results: The follow-up time was 21.2(11.7) months. The PSA value before chemotherapy was 144.9(415.3) μg/L. The days in patients undergoing androgen deprivation therapy before chemotherapy was 14(23) days. Four patients (7.3%) presented 0 in Eastern Cooperative Oncology Group scoring system and 51 patients(92.7%) presented 1. Thirty-nine patients (70.9%) completed more than 6 cycles of combined chemotherapy, 17 patients (30.9%) showed PSA<0.2 μg/L at 6 months after treatment, and 14 patients (25.5%) showed PSA<0.2 μg/L at 12 months after treatment. Twenty-eight patients (50.9%) had grade 3 to 4 neutropenia and 1 patient (1.8%) developed infectious neutropenia and died. Nausea and vomit occurred in 16 patients (29.1%). Twelve patients (21.8%) underwent dose adjustment due to adverse events in blood system. Conclusions: The short-term effect was confirmed in high-volume metastatic hormone sensitive prostate cancer using chemotherapy combined androgen-deprivation therapy, and the long-term effect remains to be seen. Myelosuppression during chemotherapy requires close attention, and taking timely examination is recommended.

Abstract
AIMS This study evaluated the effects of a potential probiotic, Bacillus sp., on the growth, serum and hepatic triglyceride, histological features of liver tissues and colonic microflora in high-fat diet-induced obese mice. METHODS AND RESULTS Sixty male C57BL/6J mice were randomly divided into five groups: mice fed a low-fat diet (Cont), mice fed a high-fat diet (Hf), Hf and orally challenged with Bacillus subtilis (Bs), B. licheniformis (Bl) and a mixture of B. subtilis and B. licheniformis (Bls). Gavage feeding was provided at week 9 and the experiment was continued for 8 weeks. Treatment with B. licheniformis and a mixture of Bacillus sp. attenuated body weight gain at the end of study and enhanced glucose tolerance by sensitizing insulin action in the Hf-fed mice. Lower serum and hepatic triglyceride and epididymal fat weight were observed in Bl and Bls groups than that of Hf group. Lesser hepatic fat deposition was observed in the Bl and Bls groups than in the Hf group. High-throughput sequencing showed that Bacillus sp. supplementation dramatically changed the colonic bacterial community in obese mice. CONCLUSIONS Bacillus licheniformis reduced body weight and improved glucose tolerance, obesity and insulin resistance in Hf-fed mice by changing colonic microbiota composition. SIGNIFICANCE AND IMPACT OF THE STUDY Orally administration of Bacillus licheniformis may reduce body weight and decrease fat deposition by modulating colonic bacterial community in Hf model.

Abstract
Abstract
Canonical Wnt/β-catenin signaling is strongly associated with cancer development and metastasis, but non-canonical Wnt signaling and its role in pancreatic ductal adenocarcinoma (PDAC) metastasis is not well understood. Wnt11 is implicated in cancer cell motility through non-canonical Wnt signaling pathways, however, previously described mechanisms are diverse and tissue specific. We investigated Wnt11 expression and its effects on PDAC cell motility/invasion and correlated these with gene expression signatures generated through single cell RNA-sequencing of PDAC tumors. Expression of Wnt11 was confirmed by RT-qPCR in PDAC cell lines derived from genetically engineered mouse models (KPC) and PDAC patient derived xenografts. Wnt11 was overexpressed in three PDAC cell lines following transfection with Wnt11 cDNA cloned into a pcDNA3.1 backbone and confirmed by RT-qPCR and western blot. siRNAs targeting Wnt11 were used to silence Wnt11 in PDAC cell lines relative to non-targeting controls and confirmed by RT-qPCR. Transwell migration/invasion assays were performed in triplicate with matched MTT proliferation assays in 3 PDAC cell lines with stable Wnt11 overexpression and 3 PDAC cell lines following Wnt11 siRNA knockdown. For single cell transcriptomic analysis, single cell suspensions were generated from 14 unique patient PDAC tumors. 10x GemCode microfluidics technology was used to isolate single cells into gel-bead in emulsion (GEM) units and were individually barcoded, lysed and reverse-transcribed. Barcoded cDNA libraries were then amplified and underwent next-generation sequencing. PDAC cell subpopulations with >4-fold levels of Wnt11 expression relative to all sequenced cells were identified and compared to the remaining tumor cell population to develop differentially expressed gene profiles. Pathways analysis of this gene set was performed using ENRICHR. Single cell transcriptomic analysis of PDAC cells derived from 14 different PDAC patients confirmed strong Wnt11 expression in subpopulations of PDAC cells. Wnt11 overexpression resulted in a 3.2-fold increase in migration and invasion (p<0.001) and RNAi-mediated depletion of Wnt11 resulted in a 6.6-fold reduction in migration and invasion (p<0.001). In PDAC cell populations with increased (>4-fold) Wnt11 expression, ERICHR analysis using the NCI pathway interaction database revealed significant enrichment in β-integrin signaling (p<0.001, z = -1.16). Wnt11 is strongly expressed in subpopulations of human PDAC cells and significantly enhances PDAC cell motility and invasion. Ongoing tail vein injection experiments with Wnt11-null PDAC cell lines and Wnt11 wildtype controls will test the in vivo role of Wnt11 in PDAC metastasis. β-integrin signaling is associated with Wnt11 expression in human PDAC tumors and may be involved in PDAC cell motility and invasion.

Abstract
Abstract
Introduction: In pancreatic ductal adenocarcinoma (PDAC), mutations in KRAS and deletion or promoter methylation of the CDKN2A gene - resulting in deregulation of the p16/CDK4/CDK6/RB axis - each occur in over 90% of cases. Therefore, combination therapy approaches targeting KRAS effectors and CDK4/6 may be a promising treatment strategy in a majority of PDAC patients. Lerociclib (G1T38) is an oral and selective CDK4/6 inhibitor in clinical development as a potential backbone therapy for multiple combination regimens in cancer. Here, we used a powerful and reliable ex vivo drug screening platform, the live tissue sensitivity assay (LTSA), to evaluate the ability of lerociclib to synergize with inhibitors of KRAS effectors across a panel of 24 well-characterized PDAC patient-derived xenografts (PDXs).
Methods: PDX tumors were sectioned into uniform tissue slices at 200 µm thickness and arrayed in 96-well plates. For each PDX model, tumor tissue slices were treated with 0.3 µM, 1 µM, and 3 µM of lerociclib, alone and in combination with identical concentrations of a PI3K (pictilisib), mTOR (AZD2014), MEK (trametinib), ERK (ulixertinib), BRAF (vemurafenib) or EGFR (erlotinib) inhibitor for 72 hours. The viabilities of individual tissue slices were measured with PrestoBlue® reagent. A quantitative drug response analysis approach was implemented in which “responder” PDXs were defined as those exhibiting a statistically significant reduction in area under the dose-response curve (AUC) for the combination treatment compared to the most efficacious single agent. Statistical significance was defined as p < 0.05 using Student’s t-test.
Results: Treatment of 24 PDAC PDXs using the LTSA revealed a range of sensitivities to each inhibitor as a single agent. When KRAS effectors and CDK4/6 were inhibited in tandem, statistically significant (p < 0.05) enhancements of efficacy were observed when lerociclib was added to pictilisib (21% of PDX models tested), ulixertinib (15%), vemurafenib (10%), erlotinib (5%), trametinib (4%), or AZD2014 (4%). These ex vivo data narrowed the focus of follow-up in vivo work; studies of PDX models in mice treated with lerociclib +/- pictilisib or ulixertinib are ongoing to validate these results. Moreover, differential gene expression and mutational analysis for responders versus non-responders identified through the PDAC PDX LTSA platform are underway, to elucidate molecular factors that predict tumor response or enrich for populations that are sensitive to CDK4/6 and PI3K/ERK inhibitors.
Conclusion: The LTSA platform was used to evaluate drug combinations in viable, PDX tumor tissue. We found that lerociclib significantly enhances the response to PI3K or ERK inhibition in a substantial proportion of the tested PDAC PDXs as measured by AUC analysis in the LTSA platform, supporting future clinical evaluation of these combinations.

Abstract
Abstract
Loss of B cell tolerance and generation of autoreactive anti-nuclear antibodies are hallmarks of systemic lupus erythematosus and lupus nephritis. The mechanism of anti-nuclear immunoglobulin accumulation and clearance in lupus nephritis pathogenesis remains largely uncharacterized. Here, we show that innate immune activation in the NZB/W F1 mouse model and human lupus nephritis biopsies rapidly reduces expression of DNase1 (also called DNase I) in renal cortex proximal tubular cells. Unexpectedly, kidney DNase1 levels were no longer affected by TLR ligand agonism upon depletion of macrophages, indicating that local macrophage activation is required for the downmodulation of DNase1 in kidney epithelial cells. To overcome the loss of endogenous DNase1, we rationally designed a hyperactive actin-resistant variant of DNase1 with improved catalytic activity and acceptable in vivo pharmacokinetics. The engineered DNase1-Fc fusion protein ameliorates nephritis in a murine model of lupus and reduces immune complex deposition/complement fixation. Our data suggest that the loss of renal DNase1 through TLR signaling or other innate immune activation impairs clearance of autoreactive anti-nuclear immune complex deposits in the kidney to promote nephritis progression. While autoantibodies and autoreactive B cell activation are central to lupus pathogenesis, we hypothesize that renal cortical epithelial cells expressing high levels of DNase1 serve as gatekeepers to prevent detrimental nuclear immune complex deposition. Our findings provide a therapeutic rationale for using an engineered hyperactive actin-resistant DNase1-Fc for lupus nephritis.

Abstract
Objective: To investigate the efficacy of soft neuroendoscopic techniques in the treatment of chronic subdural hematoma (CSDH). Methods: A retrospective analysis of 201 cases of CSDH diagnosed and treated at Beijing Shijitan Hospital (CMU) from January 2006 to December 2017 was conducted. From January 2006 to December 2010, 126 cases of CSDH were treated with skull drilling and drainage (non-endoscopic group). From January 2011 to December 2017, 75 cases of CSDH were treated with soft neuroendoscopy (endoscopic group). The operation time of the non-endoscopic and endoscopic groups, the hematoma clearance rate on the first day after surgery, the time of the drainage tube, the length of hospital stay, the incidence of complications, mortality and recurrence rate were compared. Results: There were no deaths in both groups. The average operation time of the non-endoscopic group was 43 min, compared with the average operation time of the endoscopy group of 50 min, there was no significant difference (P>0.05). The average hematoma clearance rate on the first day after surgery in the endoscopy group (98.2%) was significantly higher than that in non-endoscopic group (87.3%) (P<0.01). The average time of drainage tube in the endoscopy group (23 h) was significantly shorter than that in the non-endoscopic group (50 h) (P<0.01). On the first postoperative day, the proportion of patients with mRS≤3 in the endoscopic group was significantly higher than that in the non-endoscopic group (P<0.01). At the time of discharge, the proportion of patients with mRS≤3 in the endoscopy group was also significantly higher than that in the non-endoscopic group, P<0.05. There was no significant difference in the average hospital stay between endoscopy group (7 d) and non-endoscopic group (8 d) (P>0.05). The postoperative complication rate in the endoscopy group was significantly lower than that in the non-endoscopic group (P<0.01). During 0.5-8 years of follow-up, the recurrence rate of CSDH in the endoscopic group (5.33%) was significantly lower than that in the non-endoscopic group (15.07%) (P<0.01). Conclusion: The application of visualization features of soft neuroendoscopy in the treatment of CSDH can significantly improve hematoma clearance, shorten the time of drainage tube, reduce postoperative complications and recurrence rate, and improve surgical outcomes.

Abstract
Objective: To investigate the value of prostate health index (PHI) in the diagnosis of prostate cancer in patients with total prostate specific antigen (tPSA) <20 μg/L. Methods: Totally 1 135 patients with tPSA<20 μg/L and prostate biopsy indications at Department of Urology, Fudan University Shanghai Cancer Center from March 2013 to April 2016 were enrolled in this study. They were tested for serum tPSA, free prostate specific antigen and prostate specific antigen isoform 2, from which PHI was calculated. Diagnostic efficacy of PHI and tPSA were evaluated using receiver operating characteristic (ROC) curve analysis. The detection rates of prostate cancer were calculated in different ranges of PHI. Subgroup analysis of 716 patients, who were aged 50 or above with tPSA in the range of 4 to 10 μg/L and digital rectal examination negative, was performed. Results: In the biopsied objects with tPSA<20 μg/L, PHI was significantly higher in prostate cancer patients than that in non-cancer patients (48.4(37.4) vs. 26.5(16.9), U=52 674.00, P=0.000), PHI was also significantly higher in high-grade prostate cancer patients than that of low-grade prostate cancer patients (44.5(30.8) vs. 56.4(42.5), U=23 314.00, P=0.000). The area under the curve (AUC) of PHI for diagnosing prostate cancer was significantly higher than that of tPSA (0.771 vs. 0.627, P=0.000). When PHI was in the range of <27, 27 to <36, 36 to <55 and ≥55, the probability of prostate cancer was 9.4% (95%CI: 7.0% to 12.2%), 16.3% (95%CI: 12.2% to 20.8%), 31.0% (95%CI: 25.9% to 37.3%) and 66.4% (95%CI: 58.9% to 74.2%), respectively. Subgroup analysis showed that the AUC of PHI in diagnosing prostate cancer was significantly higher than that of tPSA (0.764 vs. 0.569, P=0.000). When PHI was in the range of <27, 27 to <36, 36 to <55 and ≥55, the probability of prostate cancer was 8.1% (95%CI: 5.4% to 11.3%), 14.0% (95%CI: 9.1% to 19.9%), 30.8% (95%CI: 23.6% to 38.7%) and 78.8% (95%CI: 66.7% to 88.9%), respectively. Conclusion: PHI is superior to tPSA in the diagnosis of prostate cancer in Chinese men with tPSA<20 μg/L.

Abstract
Lumican is secreted by pancreatic stellate cells and inhibits cancer progression. Extracellular lumican inhibits cancer cell replication and restrains growth of early-stage pancreatic adenocarcinoma (PDAC) such that patients with tumors containing stromal lumican experience a three-fold longer survival after treatment. In the present study, patient tumor tissues, ex-vivo cultures of patient-derived xenografts (PDX), PDAC stellate and tumor cells were used to investigate whether hypoxia (1% O2) within the tumor microenvironment influences stromal lumican expression and secretion. We observed that hypoxia significantly reduced lumican expression and secretion from pancreatic stellate cells, but not cancer cells. Although hypoxia enhanced lactate dehydrogenase A (LDHA) expression and lactate secretion from all cells, neither hypoxia-induced nor exogenous lactate influenced lumican expression. Autophagy was induced by hypoxia in ex vivo cultures of PDX and pancreatic stellate cells, but not cancer cells cultured in 2D. Autophagic flux inhibitors, bafilomycin A1, chloroquine diphosphate salt, and ammonium chloride prevented hypoxia-mediated reduction in lumican expression in stellate cells. Furthermore, inhibition of AMP-regulated protein kinase (AMPK) phosphorylation or hypoxia-inducible factor (HIF)-1α expression within hypoxic stellate cells restored lumican expression levels. Hypoxia did not affect lumican mRNA expression, indicating that hypoxia-induced reduction of lumican occurs post-transcriptionally; in addition, AMPK inhibition prevented hypoxia-reduced phosphorylation of the mTOR/p70S6K/4EBP signaling pathway, a key contributor to protein synthesis. Taken together, these findings demonstrate that hypoxia reduces stromal lumican in PDAC through autophagy-mediated degradation and reduction in protein synthesis within pancreatic cancer stellate cells.

Abstract
BACKGROUND Hand, foot and mouth disease (HFMD) is spread widely across Asia, and the hospitalization burden is currently not well understood. Here, we estimated serotype-specific and age-specific hospitalization rates of HFMD in Southern China. METHODS We enrolled pediatric HFMD patients admitted to 3/3 county-level hospitals, and 3/23 township-level hospitals in Anhua county, Hunan (CN). Samples were collected to identify enterovirus serotypes by RT-PCRs between October 2013 and September 2016. Information on other eligible, but un-enrolled, patients were retrospectively collected from the same six hospitals. Monthly numbers of all-cause hospitalizations were collected from each of the 23 township-level hospitals to extrapolate hospitalizations associated with HFMD among these. RESULTS During the three years, an estimated 3,236 pediatric patients were hospitalized with lab-confirmed HFMD, and among these only one case was severe. The mean hospitalization rate was 660 (95% CI: 638-684) per 100,000 person-years for lab-confirmed HFMD, with higher rates among CV-A16 and CV-A6 associated HFMD (213 vs 209 per 100,000 person-years), and lower among EV-A71, CV-A10 and other enterovirus associated HFMD (134, 39 and 66 per 100,000 person-years respectively, p<0.001). Children aged 12-23 months had the highest hospitalization rates (3,594/100,000 person-years), followed by those aged 24-35 months (1,828/100,000 person-years) and 6-11 months (1,572/100,000 person-years). Compared with other serotypes, CV-A6-associated hospitalizations were evident at younger ages. CONCLUSIONS Our study indicates a substantial hospitalization burden associated with non-severe HFMD in a rural county in southern China. Future mitigation policies should take into account the disease burden identified, and optimize interventions for HFMD.

Abstract
Intestinal epithelial cells form a physical barrier that is tightly regulated to control intestinal permeability. Proinflammatory cytokines, such as TNF-α, increase epithelial permeability through disruption of epithelial junctions. The regulation of the epithelial barrier in inflammatory gastrointestinal disease remains to be fully characterized. In this article, we show that the human inflammatory bowel disease genetic susceptibility gene C1ORF106 plays a key role in regulating gut epithelial permeability. C1ORF106 directly interacts with cytohesins to maintain functional epithelial cell junctions. C1orf106-deficient mice are hypersensitive to TNF-α-induced increase in epithelial permeability, and this is associated with increased diarrhea. This study identifies C1ORF106 as an epithelial cell junction protein, and the loss of C1ORF106 augments TNF-α-induced intestinal epithelial leakage and diarrhea that may play a critical role in the development of inflammatory bowel disease.

Abstract
AIM Endothelial cell injury assumes a fundamental part in the pathogenesis of atherosclerosis, and endothelial cell autophagy has protective effects on the development of atherosclerosis, although the underlying molecular regulation mechanism is indistinct. This study aimed to investigate whether microRNA-214-3p (miR-214-3p) is involved in the endothelial cell autophagy regulation of atherosclerosis. METHODS We utilized ApoE-/- mice provided with a high-fat diet (HFD) as atherosclerosis model. We analysed the level of miR-214-3p and the levels of autophagy-related protein 5 (ATG5) and autophagy-related protein 12 (ATG12) in the purified CD31+ endothelial cells from mouse aorta. Bioinformatics analysis and a dual-luciferase reporter assay were performed to confirm the binding target of miR-214-3p. In vitro study, human umbilical vein endothelial cells (HUVECs) were transfected with miR-214-3p mimics/inhibitor and stimulated with 100 μg/mL oxidized low-density lipoprotein (ox-LDL) for 12 hours to initiate a stress-repairing autophagic process. RESULTS In mouse models, we identified an inverse correlation between miR-214-3p, ATG5 and ATG12. We observed that in young HUVECs, ox-LDL-initiated autophagy was repressed by miR-214-3p overexpression, as evaluated by autophagic protein analysis, microtubule-associated protein 1 light chain 3B-II (LC3B-II) immunofluorescence assay and transmission electron microscopy (TEM). Also, miR-214-3p promoted ox-LDL accumulation in HUVECs and THP-1 monocyte adhesion. Conversely, in old HUVECs, suppression of miR-214-3p preserved the ability to initiate a protective autophagy reaction to the ox-LDL stimulation. CONCLUSION miR-214-3p regulates ox-LDL-initiated autophagy in HUVECs by directly targeting the 3'UTR of ATG5 and may have a suitable role in the pathogenesis of atherosclerosis.
