Abstract
Background
Despite the increased morbidity of ulcerative colitis (UC) in the developing countries, available treatments remain unsatisfactory. Therefore, it is urgent to discover more effective therapeutic strategies. Pulsatilla chinensis was widely used for the treatment of inflamed intestinal diseases including UC for thousands of years in China. However, it is unclear which compound in P. chinensis is responsible for the therapeutic effect. Our previous study reported that anemoside B4, the most abundant triterpenoid saponin isolated from P. chinensis, exerts anti-inflammatory and antioxidant effects.
Methods
Here, we used the 2, 4, 6-trinitrobenzene sulfonic acid (TNBS)-induced colitis rat model to evaluate the therapeutic effect of anemoside B4. Blood samples of colitis rat were collected for hematology analysis. The effects of anemoside B4 on inflammation-associated mediators were investigated by Enzyme-linked immunosorbent assay (ELISA) and hematoxylin and eosin staining (HE) staining. Cell proliferation or apoptosis was measured by immunofluorescence technique. The mechanisms of anemoside B4 was investigated using label-free quantitative proteomics. The level of proteins was quantified by western blotting. mRNA expression was quantified by quantitative real-time RT-PCR.
Results
The results showed that anemoside B4 ameliorated TNBS-induced colitis symptoms, including tissue damage, inflammatory cell infiltration, and pro-inflammatory cytokine production, apoptosis and slowed proliferation in the colon. Quantitative proteomic analyses discovered that 56 proteins were significantly altered by anemoside B4 in the TNBS-induced rats. These proteins were mainly clustered in tricarboxylic acid cycle (TCA) cycle and respiratory electron transport chain. Among the altered proteins, S100A9 is one of the most significantly downregulated proteins and associated with NF-κB and MAPK signaling pathways in the pathogenesis of UC. Further experiments revealed that anemoside B4 suppresses the expression of S100A9 and its downstream genes including TLR4, NF-κB, and p-JNK in colon. In vitro, S100A9 protein could active NF-κB signaling pathway in human intestinal epithelial Caco-2 cells. However, anemoside B4 could inhibit the NF-κB signaling pathway induced by S100A9 protein. Besides, it also inhibited active of NF-κB signaling pathway stimulated by LPS or IL-6.
Conclusions
Our results demonstrate that anemoside B4 prevents TNBS-induced colitis involved inhibiting the NF-κB signaling pathway through inactivating S100A9 suggesting that anemoside B4 is a promising therapeutic candidate for colitis.

Abstract
Background Despite the fact that the majority of gallstones formed in the gallbladder are mainly composed of cholesterol, as they are formed from cholesterol-supersaturated bile, there is still no consensus regarding the contribution of blood serum lipids in the pathogenesis of gallbladder stone disease (GSD). Here, we aimed to investigate the relationship between hypercholesterolemia and the risk of new-onset asymptomatic GSD, and to determine the prevalence of factors associated with new-onset asymptomatic GSD in patients with hypercholesterolemia.Methods In this case-control study, we enrolled 927 Chinese patients with new-onset asymptomatic gallstone disease and 845 healthy controls starting in August 2012. Patients were matched for age, gender, race, occupation, systolic blood pressure, diastolic blood pressure, and fasting blood glucose levels (FBG). Body mass index, nonalcoholic fatty liver disease (NAFLD) and serum lipids indexes were compared and the relationships between BMI, blood lipid and gallbladder stone hazards were examined by using logistic multivariate regression models.Results The result showed a significant higher morbidity with GSD in hypercholesterolemia than non-hypercholesterolemia patients (X2=17.211, P<0.001). Of hypercholesterolemia patients, LDL-c (OR=1.493, P=0.029) and NAFLD (OR=2.723, P=0.022) were significant risk factors for GSD, while male sex (OR=0.244, P=0.033), weight (OR=0.961, P=0.022), HDL-c (OR=0.305, P<0.001), and FBG (OR=0.687, P=0.034) significantly negatively correlated with GSD in univariate analysis. Multivariate logistic regression indicated weakly positive correlations with NAFLD (OR=3.284, P=0.054), and significant negative correlations with weight (OR=0.930, P=0.018), HDL-c (OR=0.144, P<0.001), and GSD. Conclusion Hypercholesterolemia acts as an independent risk factor for new-onset asymptomatic GSD, while obesity and NAFLD are synergistic factors. Interestingly, we are the first to report that elevated weight was inversely associated with GSD in patients with hypercholesterolemia.

Abstract
Background: Hypertension and overweight are both independent risk factors for cardiovascular disease，and being overweight can more likely to develop high blood pressure. Recent research has shown that ErbB3/HER3 played a considerable role in the development of cardiovascular disease. However, ErbB3 levels effects in the hypertensive overweight patients are unknown. This study aimed to assess the association between ErbB3 levels and hypertension with overweight in Chinese population. Methods: 128 Chinese adults aged 33-79 years, both sexes, underwent evaluation of height and weight, blood pressure, biochemical indicators and ErbB3 levels. Plasma ErbB3 levels was assessed by the Enzyme-linked immunosorbent assay (ELISA), and body mass index (BMI) was calculated as body weight divided by height squared. Participants were allocated in three groups according to blood pressure and BMI: healthy control group (CNT; n = 31; normotensive and nonoverweight), hypertension group (HT; n = 33; hypertension and nonoverweight) and hypertension with overweight group (HTO; n = 64; hypertension and overweight). A 2-tailed P<0.05 was defined to be statistically significant. Results: The difference in mean of ErbB3 levels in three groups was not significant, but had a linear decrease in males, in CNT (1.13±0.36), HT (1.03±0.36) and HTO (0.84±0.26) ng/ml, with P was 0.007. In drinking population, the ErbB3 was significantly reduced in the HTO group as compared with the CNT and HT groups (0.76±0.23 versus 1.18±0.37 and 1.20±0.30, respectively). ErbB3 levels was negatively correlated with DBP in males(r=-0.293, P=0.012), in smoking populations (r=-0.47, P=0.004) and drinking populations (r=-0.387, P=0.008). Besides, BMI in males and in drinking populations and UA in males presented negatively correlations with ErbB3 (p＜0.05). The multivariate conditional logistic regression showed that plasma ErbB3 levels was associated with reduced risk for HTO in males (OR 0.054; 95% CI: 0.007-0.412) and drink group(OR 0.002; 95% CI: 0.000-0.101). Conclusions：The apparent association between lower ErbB3 levels and overweight hypertensive patients suggested that ErbB3 may contribute to the pathogenesis to hypertension with overweight, with BMI, gender, and drinking all potentially modulating the process.Keywords: ErbB3; Hypertension; Overweight; Body mass index.

Abstract
Background: The emergency general surgery encompasses the care of critically ill patients, with a potentially high mortality if delayed. As some medical disciplines have reported a strong decrease of emergencies during the COVID-19 pandemic, remains the effect of the Lockdown on the general surgery emergencies unclear. Methods:This study is a retrospective, multicentre analysis of the general surgery emergency operations performed during the 2020 Lockdown and in the same period of 2019 in three centers covering the surgical care of the area Salzburg-North, Austria. Results: In total 165 emergency surgeries were performed in the study period of 2020 compared to 287 in Year 2019. This is a significant decrease of 122 (42.5%) emergency surgeries during the COVID-19 Lockdown (p=0.005). The average length of hospital stay in the 2019 was in median 4 days and was reduced to 3 days during the Lockdown. Appendectomy remained the most performed emergency surgery for the both periods but the operations count reduced to less than a half with 72 cases in 2019 and 33 cases in 2020 (p=0.118). Considering the ration of appendectomy vs all emergency surgeries, it represented 25 % in 2019 and 20% in 2020. The emergency colon surgery observed the strongest decrease of 75% from 17 cases in 2019 to 4 in 2020. In addition, the emergency abdominal wall hernia, cholecystectomies for acute cholecystitis, small surgeries and proctological emergencies recorded drops of 70%, 39%, 33% and 47% respectively. A strongest reduction in frequency of 6 of 13 main categories of emergency surgeries was reported from Center 1, which was the only COVID designed Center (“Hot” hospital) in the examined region.Conclusions:The emergency general surgery is an essential service that continues to run under any circumstances. Our data showed that the COVID-19 related restriction and the fear of being infected with COVID-19 in the hospital result in a significant decrease of the utilization of acute surgical care. Policies and modern alternatives are needed to ensure continued access to specialized services to prevent patients from harm.

Abstract
Background: Interactions between adipocyte and breast cancer (BC) cells have yet to be fully elucidated. Here we investigated the prognostic impact of marginal adipose tissue invasion in both luminal breast cancer (HR+/HER2-) and triple-negative breast cancer (TNBC) (HR-/HER2-). Methods: A total of 735 patients with early-stage invasive BC (1999-2014) were retrospectively registered. Median length of patient follow-up was 8.9 years. Survival curves were calculated using a Kaplan-Meier cumulative survival plot. The prognostic difference between two groups were assessed by the univariate Cox-proportional hazard regression model.Results: Patients with adipose tissue invasion (n = 614) had a significantly poorer prognosis than those without adipose tissue invasion (n = 121) in overall survival (OS) (hazard ratio, 2.1; 95% Confidence interval [CI], 1.1 to 4.0; P = 0.025). While a poorer prognosis was observed in TNBC (n = 137) than in luminal BC patients (n = 496) (hazard ratio, 0.45; 95% CI, 0.30 to 0.68, P < 0.001), this aggressive nature of TNBC was noted in node-positive disease (hazard ratio, 0.3; 95% CI, 0.18 to 0.5, P < 0.001) but not in node-negative disease (hazard ratio, 0.78; 95% CI, 0.39 to 1.55, P = 0.472), and also noted in adipose tissue invasion-positive patients (hazard ratio, 0.4; 95% CI, 0.26 to 0.6, P < 0.001) but not in adipose tissue invasion-negative patients (hazard ratio, 0.73; 95% CI, 0.16 to 3.24, P = 0.675). In addition, although patients suffering from TNBC with adipose tissue invasion had a poorer outcome than those without adipose tissue invasion (hazard ratio, 3.63; 95% CI, 1.11 to 11.84; P = 0.033), the difference was not observed in luminal BC (hazard ratio, 1.75; 95% CI, 0.64 to 4.82; P = 0.277). Conclusions: Adipose tissue invasion was correlated with poor survival in TNBC. Cancer cell invasion into local fat may be a first step on cancer progression and systemic disease in TNBC.

Published: September 2020

Abstract
Background
Long non-coding RNAs (LncRNAs) have emerged as important regulators in many physiological processes in plant. By high-throughput RNA-sequencing, many pathogen-associated lncRNAs were mapped in various plants, and some of them were proved to be involved in plant defense responses. The rice blast disease caused by Magnaporthe oryzae (M. oryzae ) is one of the most destructive diseases in rice. However, M. oryzae-induced lncRNAs in rice is yet to be studied.
Findings:
We investigated rice lncRNAs that were associated with the rice blast fungus. Totally 83 lncRNAs were up-regulated after blast fungus infection and 78 were down-regulated. Of them, the natural antisense transcripts (NATs) were the most abundant. The expression of some lncRNAs has similar pattern with their host genes or neighboring genes, suggesting a cis function of them in regulating gene transcription level. The deferentially expressed (DE) lncRNAs and genes co-expression analysis revealed some lncRNAs were associated with genes known to be involved in pathogen resistance, and these genes were enriched in terpenoid biosynthesis and defense response by Gene Ontology (GO) enrichment analysis. Interestingly, one of up-regulated DE-intronic RNA was derived from a jasmonate (JA) biosynthetic gene, lipoxygenase RLL (LOX-RLL). Levels of JAs were significantly increased after blast fungus infection. Given that JA is known to regulate blast resistance in rice, we suggested that lncRNA may be involved in JA-mediated rice resistance to blast fungus.
Conclusions
This study identified blast fungus-responsive lncRNAs in rice, which provides another layer of candidates that regulate rice and blast fungus interactions.

Published: September 2020

Abstract
Background: Osteoarthritis is the most common degenerative joint disease diagnosed in clinical practice. It is associated with significant socioeconomic burden and poor quality of life, a large proportion of which is due to knee osteoarthritis (KOA), mainly driven by total knee arthroplasty (TKA). As the difficulty of being detected early and deficiency of disease-modifying drug, the focus of KOA is shifting to disease prevention and the treatment to delay its rapid progression. Thus, the prognostic prediction models are called for, to stratify individuals to guide clinical decision making. The aim of our review is to identify and characterize reported multivariable prognostic models for KOA which concern about three clinical concerns: (1) the risk of developing KOA in general population; (2) the risk of receiving TKA in KOA patients; and (3) the outcome of TKA in KOA patients who plan to receive TKA.Methods: Studies will be identified by searching seven electronic databases. Title and abstract screening and full-text review will be accomplished by two independent reviewers. Data extraction instrument and critical appraisal instrument will be developed before formal assessment, and will be modified during a training phase in advance. Study reporting transparency, methodological quality, and risk of bias will be assessed according to Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) statement, CHecklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling Studies (CHARMS) and Prediction model Risk Of Bias ASsessment Tool (PROBAST). Prognostic prediction models will be summarized qualitatively. Quantitative metrics on predictive performance of these models will be synthesized with meta-analyses if appropriate.Discussion: Our systematic review will collate evidence from prognostic prediction models that can be used through the whole process of KOA. The review may identify models which are capable of allowing personalized preventative and therapeutic interventions to be precisely targeted at those individuals who are at the highest risk. To accomplish the prediction models to cross the translational gaps between an exploratory research method and a valued addition to precision medicine workflows, research recommendations relating to model development, validation or impact assessment will be made.Systematic review registration: PROSPERO (registered, waiting for assessment, ID 203543)

Abstract
BackgroundMesenchymal stem cells (MSCs), including adipose-derived mesenchymal stem cells (ADSCs), have been shown to attenuate organ damage in acute respiratory distress syndrome (ARDS) and sepsis; however, the underlying mechanisms have not been fully understood. In this study, we aimed to explore the potential roles and molecular mechanisms of action of ADSCs in histone-induced endothelial damage. MethodsMale C57BL/6N mice were intravenously injected with ADSCs, followed by histones or a vehicle. The mice in each group were assessed for survival, pulmonary vascular permeability, and histological changes. A co-culture model with primary human umbilical vein endothelial cells (HUVECs) exposed to histones was used to clarify the paracrine effect of ADSCs. Overexpression and inhibition of miR-126 ADSCs were also examined as causative factors for endothelial protection.ResultsThe administration of ADSCs markedly improved survival, inhibited histone-mediated lung hemorrhage and edema, and attenuated vascular hyper-permeability in mice. ADSCs were engrafted in the injured lung and attenuated histone-induced endothelial cell apoptosis. ADSCs showed endothelial protection (via a paracrine effect) and Akt phosphorylation in the histone-exposed HUVECs. Notably, increased Akt phosphorylation by ADSCs was mostly mediated by exosomes in histone-induced cytotoxicity and lung damage. Moreover, inhibition of miR-126, which is known to be present in exosomes, in ADSCs did not increase Akt phosphorylation in histone-exposed HUVECs. ConclusionADSC-derived exosomes may exert protective effects on endothelial cells via activation of the PI3K/Akt pathway.

Published: September 2020

Abstract
Background
The existences of soluble lignin, furfural and HMF in industrial pre-hydrolysis liquor (PHL) can inhibit its bioconversion into bioethanol and other bio-chemicals. Although various technologies have been carried out to remove these inhibitors, a undesirable sugars removal is also happened during the process. Hence, polystyrene divinylbenzene (PS-DVB) resin was used as adsorptive material to simultaneously remove fermentation inhibitors while retain sugars with higher yield for improving the fermentability of PHL after acid-hydrolysis (A-PHL) treatment. The fermentability of treated PHL was evaluated by the bioconversion into ethanol and xylosic acid (XA).
Results
Results showed that an highest xylose concentration (101.1 g/L) in PHL could be obtained by acid-hydrolysis at 100 oC for 80 min with 4% acid, while concentration of fermentation inhibitors (furfural, HMF and lignin) could also be significantly improved. After treating, not only 97% of lignin, 92% of furfural, and 97% of HMF were removed from solution, but also 96% of xylose was retained for subsequent fermentation. With resin treatment, the fermentability of A-PHL could be improved by 162–282% for ethanol production from A-PHL with 30–50 g/L xylose and by 18–828% for XA production from A-PHL with 90–150 g/L xylose.
Conclusions
These results confirmed that PS-DVB resin can remove inhibitors from PHL before producing value-added products by bioconversion. In addition, the work will ideally provide a concept by which pulping facilities could go about producing value-added chemicals from existing waste streams.
