Abstract
OBJECTIVE The aim of the study was to investigate the effect of lncRNA XIST on the proliferation and epithelial-mesenchymal transition (EMT) of retinoblastoma (RB) and its relevant mechanism. PATIENTS AND METHODS 60 RB patients who were treated in our hospital were collected. The expression of XIST in tissues and cells was detected by qRT-PCR, and the effect of XIST on the prognosis of RB cells was observed. Stable and transient over-expression and suppression vectors were established and transfected into RB cells WERI-RB1 and Y79. CCK-8, transwell, and flow cytometry were used to evaluate the proliferation, invasion, and apoptosis of transfected cells. Western Blot was used to detect apoptosis-related proteins and EMT-related proteins. Dual-Luciferase report was used to determine the relationship between XIST and miR-142-5p. RNA pull-down and RIP experiments were used to determine the relationship between XIST and miR-142-5p. RESULTS XIST was highly expressed in RB patients, which had a high diagnostic value. Patients with XIST high expression had a poor prognosis. After overexpression of XIST, the proliferation, invasion and EMT of cells increased, and apoptosis rate decreased, while inhibition of Ptv1 had the opposite effect. Dual-Luciferase report confirmed that XIST could target miR-142-5p. Functional analysis showed that the overexpression of miR-142-5p inhibited the proliferation, invasion and EMT of RB cells and promoted cell apoptosis. Rescue experiments showed that miR-142-5p could eliminate the inhibition of miR-142-5p on the proliferation, invasion, and EMT of RB cells by upregulating XIST expression. CONCLUSIONS Ptv1 can promote the proliferation, invasion, and EMT of RB cells by regulating miR-142-5p.

Abstract
Cementum, a specialized bony layer covering an entire molar root surface, anchors teeth into alveolar bone. Gli1, a key transcriptional activator in Hedgehog signaling, has been identified as a mesenchymal progenitor cell marker in various tissues, including the periodontal ligament (PDL). To address the mechanisms by which Gli1+ progenitor cells contribute to cementogenesis, we used the Gli1lacZ/+ knock-in line to mark Gli1+ progenitors and the Gli1CreERT2/+; R26RtdTomato/+ line (named Gli1Lin) to trace Gli1 progeny cells during cementogenesis. Our data unexpectedly displayed a biphasic feature of Gli1+ PDL progenitor cells and cementum growth: a negative relationship between Gli1+ progenitor cell number and cementogenesis but a positive correlation between Gli1-derived acellular and cellular cementoblast cell number and cementum growth. DTA-ablation of Gli1Lin cells led to a cementum hypoplasia, including a significant reduction of both acellular and cellular cementoblast cells. Gain-of-function studies (by constitutive stabilization of β-catenin in Gli1Lin cells) revealed a cementum hyperplasia. A loss of function (by conditional deletion of β-catenin in Gli1+ cells) resulted in a reduction of postnatal cementum growth. Together, our studies support a vital role of Gli1+ progenitor cells in contribution to both types of cementum, in which canonical Wnt/β-catenin signaling positively regulates the differentiation of Gli1+ progenitors to cementoblasts during cementogenesis.

Abstract
Predicted sea level fluctuations and sea level rise with climate change will lead to inundation of coastal and estuarine soils. Coastal wetlands usually contain large amounts of organic matter, which can be potential sources of greenhouse gas emissions (GHGs; CO2, CH4, N2O) during decomposition, but there are limited studies on the effects of sea level variation on GHGs in coastal wetlands. We measured the effect of brackish water inundation and wetting and drying cycles on GHG emissions from coastal wetland soil cores that supported four different vegetation types: Apium gravedens (AG), Leptospermum lanigerum (LL), Phragmites australis (PA) and Paspalum distichum (PD) from the estuarine floodplain of the Aire River in south-western Victoria, Australia. Intact soil cores were incubated under either dry, flooded, or a 14 day wet-dry cycle treatments for a total of 56 days at a constant temperature of 23 °C. CO2, CH4, and N2O fluxes were investigated in closed chambers and measured with gas chromatography. In the dry treatment, a positive correlation was found between soil organic carbon (SOC) and CO2 flux, and between SOC and CH4 flux. Higher SOC is indicative of higher amounts of soil organic matter (SOM) which acts as a source of substrate for microbes to produce CO2 or CH4 emissions under aerobic or anaerobic conditions. The NO2- and NO3- concentrations were positively correlated with N2O emissions in the wet-dry cycle treatment. NO2- and NO3- provide a supply of substrate for denitrification. The flooded treatment decreased cumulative CO2 emissions by 34%, 25% and 14% at the LL, PA, PD sites, respectively, and decreased cumulative N2O emissions by 42%, 39% and 43% at the AG, LL and PA sites, compared to the dry treatment. The wet-dry cycle treatment and dry treatment decreased cumulative CH4 emissions for all vegetation types compared to the flooded treatment. The redox potential (Eh) was negatively correlated with CH4 flux and positively correlated N2O flux at all sites. This study highlights the significance of sea level fluctuations when estimating GHG flux from coastal and estuarine floodplains which are highly vulnerable to inundation, and the role of SOC and mineral N as important drivers affecting GHG flux.

Abstract
OBJECTIVE Long non-coding RNAs (lncRNAs) play critical roles in tumour progression. However, the function of lncRNA small nucleolar RNA host gene 11 (SNHG11) in glioma has not been mentioned before. Our study aims to uncover the biological roles of SNHG11 in the progression of glioma and throw light for clinical treatment of glioma. MATERIALS AND METHODS The Gene Expression Profiling Interactive Analysis (GEPIA) dataset was used to analyze the SNHG11 expression between glioma and normal tissue, as well as survival benefit. The quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to detect SNHG11 and miR-154-5p expression. Celltiter-Glo, colony formation, and transwell assays were utilized to detect the influence of SNHG11 to the malignancy of U87 and U251 cells. The underlying pathways affected by SNHG11 were measured using Western blot. Furthermore, Luciferase reporter assay was applied to verify the interaction between SNHG11 and miR-154-5p. RESULTS SNHG11 was upregulated in glioblastoma tissues and five malignant glioma cell lines. SNHG11 expression was negatively correlated with overall survival of glioma patients. Moreover, silencing of SNHG11 could decrease glioma cell viability both in vitro and in vivo. Furthermore, the inhibition of SNHG11 suppressed proliferation, invasion and migration via regulating epithelial-mesenchymal transition (EMT). In addition, SNHG11 could bind miRNA-154-5p and negatively regulate its level. CONCLUSIONS SNHG11 functioned as an oncogene in glioma and promoted proliferation, invasion, and migration via EMT by sponging miR-154-5p. These findings provided a new therapeutic target for glioma.

Abstract
BACKGROUND Accurate and robust pathological image analysis for colorectal cancer (CRC) diagnosis is time-consuming and knowledge-intensive, but is essential for CRC patients' treatment. The current heavy workload of pathologists in clinics/hospitals may easily lead to unconscious misdiagnosis of CRC based on daily image analyses. METHODS Based on a state-of-the-art transfer-learned deep convolutional neural network in artificial intelligence (AI), we proposed a novel patch aggregation strategy for clinic CRC diagnosis using weakly labeled pathological whole-slide image (WSI) patches. This approach was trained and validated using an unprecedented and enormously large number of 170,099 patches, > 14,680 WSIs, from > 9631 subjects that covered diverse and representative clinical cases from multi-independent-sources across China, the USA, and Germany. RESULTS Our innovative AI tool consistently and nearly perfectly agreed with (average Kappa statistic 0.896) and even often better than most of the experienced expert pathologists when tested in diagnosing CRC WSIs from multicenters. The average area under the receiver operating characteristics curve (AUC) of AI was greater than that of the pathologists (0.988 vs 0.970) and achieved the best performance among the application of other AI methods to CRC diagnosis. Our AI-generated heatmap highlights the image regions of cancer tissue/cells. CONCLUSIONS This first-ever generalizable AI system can handle large amounts of WSIs consistently and robustly without potential bias due to fatigue commonly experienced by clinical pathologists. It will drastically alleviate the heavy clinical burden of daily pathology diagnosis and improve the treatment for CRC patients. This tool is generalizable to other cancer diagnosis based on image recognition.

Abstract
OBJECTIVE To explore the role of T-box 2 (TBX2) in esophageal squamous cell carcinomas (ESCC). PATIENTS AND METHODS Quantitative real-time polymerase chain reaction (PCR) and Western blot (WB) assays were used to detect the expression level of TBX2 in tissues and cells. Transwell assays were conducted for determination of cell invasion and migration. RESULTS The results suggested that the TBX2 was upregulated in ESCC tissues. Further, high expression of TBX2 expression was associated with tumor size, differentiation, distant metastasis, and TNM stage. In our in-vitro study, we decreased the expression of TBX2 in ESCC cells by transfection using LipofectamineTM 3000. The results from the transwell assay suggested that the downregulation of TBX2 could significantly suppress cell migration and invasion. Besides, WB results indicated that epithelial-mesenchymal transition (EMT)-related protein expressions were also changed after transfection. CONCLUSIONS TBX2, as an oncogene, could promote the progress of ESCC by affecting the transfer ability in tumor cells.

Abstract
This study was performed to assess the effect of correcting skeletal class II malocclusion based on the application of computer-assisted design and manufacturing (CAD/CAM) cutting and drilling guides accompanied with pre-bent titanium plates. Fifty patients with skeletal class II malocclusion were recruited into this prospective randomized controlled clinical trial and assigned to two groups. Patients underwent bilateral sagittal split ramus osteotomy directed by CAD/CAM cutting and drilling guides accompanied with pre-bent titanium plates (group A) or CAD/CAM splints (group B). Postoperative assessments were performed. Differences between the virtually simulated and postoperative models were measured. Patients in both groups had a satisfactory occlusion and appearance. More accurate repositioning of the proximal segment was found in group A than in group B when comparing linear and angular differences to reference planes; however, no significant difference was revealed for the distal segment. In conclusion, CAD/CAM cutting and drilling guides with pre-bent titanium plates can provide considerable surgical accuracy for the positional control of the proximal segments in bilateral sagittal split ramus osteotomy for the correction of skeletal class II deformities.

Abstract
Abstract
Background
In cirrhosis, frailty is associated with increased risk of morbidity and mortality, including an increased risk of hospitalization. While frailty is established as a prognostic marker in cirrhosis, its impact on the progression of cirrhosis, especially in earlier stages of disease, remains unclear.
Aims
To determine the relationship between frailty and risk of cirrhosis progression, mortality, and unplanned hospitalizations in patients with cirrhosis across the spectrum of disease.
Methods
Adult patients with cirrhosis from two centers in North America and one in India were included in this retrospective review of prospectively collected data. Frailty was measured at baseline using the Liver Frailty Index (LFI), comprising grip strength, chair stands, and balance testing. Progression of cirrhosis was defined by an increase from one ordinal stage to the next using the D’Amico classification. Factors associated with progression, mortality, and hospitalizations were evaluated using multivariate competing risk regression models, with transplant as a competing risk.

In total, 822 patients with cirrhosis were included. The median MELD score was 15.5 ± 6.0. Of these patients, 201 (24.5%), 488 (59.4%), and 133 (16.2%) were classified as frail, pre-frail, and robust, respectively. Over a median follow up time of 1.2 years, 60 (7.3%) patients developed progression of cirrhosis, 187 (22.7%) died, 233 (28.3%) underwent liver transplantation, and 342 (41.6%) were alive without cirrhosis progression or transplant. Adjusting for age, sex, and MELD at baseline, being frail was associated with an increased risk of progression to the next cirrhosis stage or to death as compared to being robust (HR 2.47, 95% CI 1.63–3.76, p<0.001). As a continuous variable, every increase in the LFI by 0.1 unit increased the risk of decompensation or death by 1.05-fold (95% CI 1.04–1.07, p<0.001). Similarly, patients who were frail were more likely to be hospitalized as compared to patients who were robust (HR 2.88, 95% CI 2.08–3.98, p<0.001).
Conclusions
Frailty was associated with an increased risk of cirrhosis progression or death, and hospitalization, independent of MELD at baseline. Future studies are needed to evaluate the possibility of slowing cirrhosis disease progression by reversing or preventing frailty.

Abstract
PURPOSE To evaluate the safety and efficacy of Cyberknife® (CK) for the treatment of primary or recurring thymic tumours. MATERIALS AND METHODS We retrospectively reviewed 12 patients (16 tumour lesions) with primary or recurring thymic tumours who were treated with CK between March 2008 and October 2017. Their data was stored in prospectively collected database. Kaplan-Meier method was used to calculate survival curves. RESULTS Five patients (41.7%), who had inoperable disease or refused surgery, were treated with CK initially, and 7 patients (58.3%) were treated with CK when they had recurrence diseases. The disease sites treated with CK were primary tumour site (5), regional lymph nodes (4), tumour bed (3), chest wall (2), pleura (1), and bone (1). The median target volume was 43.8 cm3 (range, 13.1-302.5cm3) for the 16 tumour lesions. The median follow-up time was 69.3 months (range, 9.7-124.8 months). The median survival time was 48.2 months, and the 5-year and 10-year OS rates were 68.2% and 45.5%, respectively. A high response rate for the tumour lesions irradiated with CK was obtained. Only one patient (8%) experienced in-field recurrence, and the 5-year local recurrence free survival was 90.9%. A case indicated that CK may induce the abscopal effect, which provides the potential to combine CK and immunotherapy. No severe radiation related toxicities were observed, and no treatment related death occurred. CONCLUSION CK treatment resulted in good outcomes, particularly local control, with minimal side effects, in highly selected patients with primary and recurring thymic tumours. More studies with larger sample are needed.

Abstract
Objectives: Giant cell arteritis (GCA) can manifest in cranial and/or extracranial arteries. We investigated the distribution of affected arteries on vascular ultrasound (VUS) among patients with new-onset or prior-onset GCA.Method: We retrospectively studied patients with either new-onset or prior-onset GCA and an abnormal VUS, from 2013 to 2017. Trained vascular technologists imaged the bilateral temporal arteries and carotid, axillary, and subclavian arteries. Vascular medicine physicians interpreted the images. Vasculitis-related abnormalities in individual vessels and their distribution (temporal artery, large artery, or both) were evaluated. Phi coefficients (φ) and Fisher's exact test were used to assess correlations among individual abnormal arteries.Results: Among 66 GCA patients, 28.8% had prior-onset GCA (median duration 17.8 months). Acute arteritis on VUS was observed in the majority of patients with both new-onset (72.3%) and prior-onset GCA (68.4%); the remainder had hyperechoic wall thickening without acute arteritis. Involvement of the temporal arteries only (45.5%) or large arteries only (34.8%) was more common than involvement of both (19.7%); this finding was similar in new-onset and prior-onset GCA. There were moderate positive correlations among temporal artery branches (φ = 0.51-0.58, p < 0.003) and among axillary and subclavian arteries (φ = 0.51-0.77, p < 0.003), and moderate negative correlations between abnormalities in the temporal and large arteries (φ = -0.46 to -0.58, p < 0.003).Conclusion: On VUS, vasculitis-related abnormalities in the temporal arteries only or large arteries only were more common than concurrent temporal and large artery abnormalities in patients with both new-onset GCA and prior-onset GCA.

Abstract
OBJECTIVE To explore the regulatory mechanism of lncRNA NORAD on proliferation and invasion of ovarian cancer cells through miR-199a-3p. PATIENTS AND METHODS Eighty-six ovarian cancer tissues and 86 tissues adjacent to cancer, human ovarian cancer cell lines SKOV3, HO-8910, A2780, OVCAR-3, and human normal ovarian epithelial cell line IOSE80 were collected. MiR-199a-3p-mimics, miR-199a-3p-inhibitor, miR-NC, si-NORAD, Sh-NORAD, and NC were transfected into HO-8910 and A2780 cells, the expression levels of lncRNA NORAD and miR-199a-3p in ovarian cancer tissues and cells were detected by qRT-PCR, and the expression levels of N-cadherin, E-cadherin, and vimentin in cells were detected by WB. Cell Counting Kit-8 (CCK-8), transwell, and cell scratch tests were used to detect proliferation, invasion, and migration of cells, and the relationship between lncRNA NORAD and miR-199a-3p was confirmed by the Dual-Luciferase reporter assay. RESULTS LncRNA NORAD was highly expressed and miR-199a-3p was lowly expressed in ovarian cancer, and the expression levels of LNCRNARAD and miR-199a-3p were negatively correlated. Cell experiments showed that inhibiting the expression of lncRNA NORAD or up-regulating the expression of miR-199a-3p could inhibit the proliferation, invasion, migration, and EMT of ovarian cancer cells, while up-regulating the expression of lncRNA NORAD or inhibiting the expression of miR-199a-3p could promote their proliferation, invasion, migration, and EMT. Dual-Luciferase reporter assay confirmed that there was a regulatory relationship between lncRNA NORAD and miR-199a-3p. CONCLUSIONS LncRNA NORAD was highly expressed in ovarian cancer tissues, while silencing lncRNA NORAD expression could inhibit the proliferation, invasion, migration, and EMT of ovarian cancer cells by regulating miR-199a-3p, which might be a new target for the diagnosis and treatment of ovarian cancer.

Abstract
The aim of this study was to explore the dynamic changes in characteristic serum metabolic markers and pathways during early sepsis in rats. By using cecal ligation and puncture (CLP), we made rat models of sepsis, which were randomly divided into 5 groups with 10 rats in each group: group A, group B, group C, group D, and group E. We collected 2 mL of arterial blood at 0, 6, 12, 24, and 48 hours from rats in group A-E respectively and isolated serum via centrifugation. Next, adopting metabolomics analysis methods, we screened for metabolites from the animal serum with statistically and biologically significant abundance changes, and used the KEGG database to analyze the respective metabolic pathways. In all, our findings reveal that D-glucosamine 6-phosphate, D-glucosamine phosphate, α-D-glucosamine 1-phosphate, D-glucosamine 1-phosphate, and 5-hydroxy isocyanate decline continuously from 12 hours, while L-phenylalanine, (S) -α-amino-β-phenylpropionic acid, 5-methoxy indole acetic acid salt, 5-methoxy indole acetic acid, goose deoxyglycolic acid salt, goose deoxyglycolic acid, and Chen's deoxygenated sugar alcohol started to decrease from 6 hours. Additionally, 3.2,3-Bis-O-(geranyl geranyl)-sn-glycerol- 1-phosphoric acid-L-serine levels rose continuously from 12 hours. We found 13 differentially regulated ions, primarily ones involved in pathways responsible for the metabolism of sugar, amino acids, and lipids, which are related to the disorder of energy metabolism. Our findings mark serum-derived D-glucosamine and its phosphorous derivatives as characteristic metabolic markers of sepsis in rats.

Abstract
ABSTRACT Ketosis can seriously impair cow performance. This study detected changes in prepartum blood metabolic parameters for predicting postpartum ketosis occurrence in dairy cows. Body condition score (BCS) was assessed before and after delivery. Blood samples of 63 cows were collected from 10 days before calving to 10 days after calving to measure metabolic parameters including β-hydroxybutyric acid (BHBA), non-esterified fatty acid (NEFA), glucose (GLU), total bilirubin (TBIL), direct bilirubin (DBIL), indirect bilirubin (IBIL), total protein (TP), albumin (ALB), globulin (GLO), alanine aminotransferase (ALT), and aspartate aminotransferase (AST). There was a postpartum subclinical ketosis incidence of 42.25%. Compared with prepartum, plasma, levels of BHBA, AST, and NEFA significantly increased postpartum, and prepartum AST (R=0.57) and NEFA (R=0.45) showed a significant positive correlation with ketosis postpartum. Plasma GLU level significantly decreased postpartum and was significantly negatively correlated with ketosis (R=-0.21). Receiver operating characteristic curve analysis revealed prepartum BSC < 2.88, and prepartum plasma AST > 68.0 U/L, GLU < 3.97mmol/L, NEFA > 0.27mmol/L, and BHBA > 0.43mmol/L, indicating a high risk of subclinical ketosis postpartum. These levels can be used as risk indicators to predict the occurrence of subclinical ketosis in postpartum cows.

Abstract
Furans represent one of the most important classes of intermediates in the conversion of non-edible lignocellulosic biomass into bio-based chemicals and fuels. At present, bio-furan derivatives are generally obtained from cellulose and hemicellulose fractions of biomass via the acid-catalyzed dehydration of their relative C6-C5 sugars and then converted into a wide range of products. Furfural (FUR) and 5-hydroxymethylfurfural (HMF) are surely the most used furan-based feedstocks since their chemical structure allows the preparation of various high-value-added chemicals. Among several well-established catalytic approaches, hydrogenation and oxygenation processes have been efficiently adopted for upgrading furans; however, harsh reaction conditions are generally required. In this review, we aim to discuss the conversion of biomass derived FUR and HMF through unconventional (transfer hydrogenation, photocatalytic and electrocatalytic) catalytic processes promoted by heterogeneous catalytic systems. The reaction conditions adopted, the chemical nature and the physico-chemical properties of the most employed heterogeneous systems in enhancing the catalytic activity and in driving the selectivity to desired products are presented and compared. At the same time, the latest results in the production of FUR and HMF through novel environmental friendly processes starting from lignocellulose as well as from wastes and by-products obtained in the processing of biomass are also overviewed.

Abstract
ABSTRACT The objective of this study was to investigate the influence of plasma pathological changes before timed artificial insemination (TAI) on pregnancy of cows. The contents of estrogen (E2), progesterone (P4), glucose (Glu), selenium (Se), brain-derived neurotrophic factor (BDNF), and histamine (HIS) in plasma of 48 Holstein cows were measured before TAI. According to the estrus detection, the cows were divided into estrus (E) and anestrus (A) groups. After pregnancy testing at 28 d after TAI, two groups of E and A were divided into positive pregnancy of E group (EP+), negative pregnancy of E group (EP-), positive pregnancy of A group (AP+), and negative pregnancy of A group (AP-). The contents of E2, P4, Glu, Se, BDNF and hIS significantly differed among the four groups (P<0.01). The ROC analysis was used to determine the risk of negative pregnancy test (-) after TAI was increased when plasma E2 was less than 46.45 pmol/L in cows before TAI. The changes in E2, P4,hIS, Glu, and BDNF in the blood of natural estrus and natural anestrus cows affected the pregnancy after TAI. the level of E2 in plasma may be used to assess the risk of negative pregnancy after TAI.

Abstract
To assess the correlation between thyroid function and glucolipid metabolism in type 1 diabetic adults. A retrospective analysis was conducted in 230 type 1 diabetic adults who were hospitalized in the Department of Endocrinology of Shandong Provincial Hospital Affiliated to Shandong University from January 2008 to January 2020. It showed that thyroid stimulating hormone(TSH) was significantly positively correlated with total cholesterol (TC) (r=0.239), triglycerides (TG) (r=0.166) and low-density lipoprotein cholesterol (LDL-C) (r=0.249), respectively (all P<0.05). Free triiodothyronine (FT3) was significantly negatively correlated with fasting plasma glucose (FPG) (r=-0.272), glycated hemoglobin (HbA1c) (r=-0.240), TC (r=-0.197) and LDL-C (r=-0.220), respectively (all P<0.05). Free thyroxine (FT4) was negatively correlated with TC (r=-0.171) and LDL-C (r=-0.170), respectively (all P<0.05). TC was an independent predictor of TSH, FT3 and FT4, FT3 and FT4 were independent predictors of HbA1c. TSH was an independent predictor of TC, TG and LDL-C. Thyroid function is closely related to glucolipid metabolism in type 1 diabetic adults.

Abstract
This study aims to evaluated the prognostic and predictive roles of DNA mismatch repair status in colon cancer patients treated with oxaliplatin-based chemotherapy. From 2005 to 2008, patients who underwent curative surgical resection for high-risk stage II or stage III colon cancer were recruited in this study. These patients had been received oxaliplatin-based chemotherapy. A total 324 patients were included (41.7% at stage II and 58.3% at stage III), and 59 patients (18.2%) exhibited mismatch repair-deficient (dMMR). The prognostic analysis revealed an increase in disease-free survival (DFS) for dMMR patients versus proficient MMR (pMMR) patients (81.4% versus 64.2%, P = 0.009), and overall survival (OS) (86.4% versus 69.1%, P = 0.004). Among the 82 patients who did not receive adjuvant therapy, the 5-year DFS was significantly higher in patients with dMMR (81.3%) than in patients with pMMR (49.7%, P = 0.040). In the multivariate models, dMMR was independently associated with improved DFS (HR = 2.171, 95% CI: 1.108 - 4.253, P = 0.024) and OS (HR = 2.521, 95% CI: 1.190 - 5.339, P = 0.016). In the predictive analysis, it was observed that the benefit of treatment significantly differed according to the DNA MMR status (P = 0.020). Compared with surgery alone, oxaliplatin-based adjuvant chemotherapy improved the 5-year DFS (69.9% versus 56.2%, P = 0.024) among patients with pMMR in the multivariable analysis (HR = 0.794, 95% CI = 0.646 - 0.976, P = 0.029). In contrast, the oxaliplatin-based chemotherapy in the group with dMMR had no benefit in DFS (83.1% versus 81.8%, HR 1.040, 95% CI: 0.276 - 3.922, P = 0.954). Patients with dMMR colon cancer are associated with improved survival rates, compared with pMMR colon cancer. MMR status is an independent prognostic biomarker for DFS in patients with high-risk stage II and stage III colon cancer. Oxaliplatin-based adjuvant chemotherapy mainly benefits patients with pMMR, but may not benefit patients with tumors exhibiting dMMR.

Abstract
BACKGROUND Subsequent to the implementation of the universal salt iodisation policy, China has all but eliminated the iodine deficiency disorders. However, pregnant women are still experiencing mild iodine deficiency. The present study explored factors that could relate to mild iodine deficiency in pregnant women. METHODS In total, 2400 pregnant women were enrolled using a multistage, stratified, random sampling method in Shanghai. Data were collected via a standardised questionnaire. The urine samples and household cooking salt samples were collected for the detection of urinary iodine and salt iodine concentrations. RESULTS The median urinary iodine concentration (MUIC) was 148.0 μg L-1 for all participants, and 155.0 μg L-1 , 151.0 μg L-1 and 139.6 μg L-1 in the first, second and third trimesters. The MUIC in the third trimester was significantly lower than that of the first trimester (P < 0.05). The usage rates of iodised salt and qualified-iodised salt were 71.5% and 59.4%, respectively. Iodine-related knowledge score composition ratio was significantly different between the high and low UIC groups (P < 0.05). Participants' MUIC increased significantly with the increases in iodine-related knowledge score (P < 0.001). The third trimester was a significant risk factor for high UIC, whereas high iodine-related knowledge score, actively learning dietary knowledge and having a habit of consuming iodine-rich food were significant protective factors for high UIC (P < 0.05). CONCLUSIONS Iodine level is adequate among pregnant women in Shanghai during the first and the second trimesters, although it is is insufficient in the third trimester. Good iodine-related knowledge, attitudes and behaviours are important for pregnant women with respect to maintaining adequate urinary iodine.

Abstract
Bromodomain containing protein 4 (BRD4) has been demonstrated to play critical roles in cellular proliferation and cell cycle progression. In this study, using the BRD4 inhibitor Fragment 9 as a lead compound, a series of imidazolopyridone derivatives were designed and tested for their inhibitory activity against BRD4 protein in vitro. Among them, HB100-A7 showed excellent BRD4(1) inhibitory activities with an IC50 value of 0.035 μM in amplified luminescent proximity homogeneous assay (Alphascreen). The result of MTT assay showed that HB100-A7 could suppress the proliferation of pancreatic cancer cells. In addition, flow cytometry further illustrated that HB100-A7 treatment resulted in G0/G1 phase arrest and promoted apoptosis of BxPc3 cells. Furthermore, the in vivo study found that HB100-A7 displayed significant tumor growth inhibition in a pancreatic mouse tumor model (Panc-02). Moreover, IHC staining suggested that HB100-A7 induce cell apoptosis in pancreatic cancer tumor tissue. Together, this study revealed, for the first time, HB100-A7 is a promising lead compound for further development as a new generation of small molecule inhibitors targeting the BRD4 protein.

Abstract
OBJECTIVE MicroRNAs have been implicated to play a crucial regulating role in human cancers. The study aims to explore the role and clinical significance of miR-497 in pancreatic ductal adenocarcinoma (PDAC). PATIENTS AND METHODS The relative expression of miR-497 in human PDAC tissue samples and adjacent normal tissues was measured using the quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Cell Counting Kit (CCK-8) assay, cell migration, and invasion assays were performed to detect cell proliferation and invasion ability. Downstream target gene was confirmed by using luciferase activity assays. QRT-PCR and Western blotting assays also were performed. RESULTS We found that miR-497 expression was significantly downregulated in PDAC tissues and cells. Lower miR-497 expression associated with lymph node metastasis and predicts a poor prognosis in PDAC patients. In in vitro assay, we demonstrated that miR-497 overexpression inhibited cell proliferation, migration, and invasion of PDAC. Furthermore, we demonstrated that HMGA2 was a direct target of miR-497 in PDAC cells. MiR-497 inhibited cell proliferation and invasion by regulating HMGA2 expression. CONCLUSIONS Our results indicated that miR-497 may serve as a predictor for PDAC and could be a novel target of PDAC treatment.

Abstract
INTRODUCTION AND OBJECTIVES Allergen-specific immunotherapy (ASIT) is the only allergic disease-modifying therapy available for children and adults, and recombinant allergens are an interesting approach to improve allergy diagnosis and ASIT. Tyrophagus putrescentiae is a common storage mite that produces potent allergens. The aim of this study was to express and characterize recombinant group 4 allergen protein of T. putrescentiae (Tyr p 4), and to further investigate allergenicity and potential epitopes of Tyr p 4. MATERIALS AND METHODS The cDNA encoding Tyr p 4 was generated by RT-PCR and subcloned into pET-28a(+) plasmid. The plasmid was then transformed into E. coli cells for expression. After purification by nickel affinity chromatography and identification by SDS-PAGE, recombinant Tyr p 4 protein was used for a skin prick test and an ELISA to determine the allergic response. RESULTS Study participants' allergic response rate to Tyr p 4 protein was 13.3% (16/120). Eight B-cell epitopes and three T-cell epitopes of Tyr p 4 were predicted. CONCLUSIONS Similar to group 4 allergens of other species of mite, allergenicity of Tyr p 4 is weak. The expression, characterization and epitope prediction of recombinant Tyr p 4 protein provide a foundation for further study of this allergen in the diagnosis and ASIT of storage mite allergy.
