Abstract Intrahepatic cholangiocarcinoma (ICC) is a rare but highly aggressive malignant tumor arising within the liver, with a 5-year survival rate of only 20–40% after surgery. The role of interleukin-8 (IL-8) in ICC progression remains elusive. A transcriptomic approach based on IL-8 stimulation first revealed significant upregulation of the prometastatic gene CD97 and key epithelial–mesenchymal transition (EMT) factors E-cadherin and vimentin. Immunohistochemistry of 125 ICC tissues confirmed the positive correlation between IL-8 and CD97. Multivariable Cox regression indicated that they are both independent predictors of ICC prognosis. Mechanistically, IL-8 treatment induced CD97 expression at 50 and 100 ng/ml in QBC-939 and QBE cells, respectively. Moreover, the induction of cell migration and invasion upon IL-8 treatment was attenuated by CD97 RNA interference, and the expression of EMT-associated genes was dramatically inhibited. To determine whether CXCR1 or CXCR2 are downstream effectors of IL-8, siCXCR2 was applied and shown to significantly attenuate the oncogenic effects of IL-8 by inhibiting the phosphorylation of PI3K/AKT. Finally, the induction of CD97 expression by the PI3K pathway was verified by treatment with the inhibitor LY294002. In vivo, the significant tumor growth and lung metastasis effects induced by intraperitoneal injection of IL-8 were greatly inhibited by silencing CD97 in nude mice. Collectively, the study presents a novel mechanism of the IL-8-CXCR2-PI3K/AKT axis in regulating CD97 expression, which leads to ICC metastasis mainly through EMT. The study may provide alternatives for targeting the tumor microenvironment in metastatic ICC.

Abstract With the increase in extremely low birth weight (ELBW) infants, their outcome attracted worldwide attention. However, in China, the related studies are rare. The hospitalized records of ELBW infants discharged from twenty-six neonatal intensive care units in Guangdong Province of China during 2008–2017 were analyzed. A total of 2575 ELBW infants were enrolled and the overall survival rate was 55.11%. From 2008 to 2017, the number of ELBW infants increased rapidly from 91 to 466, and the survival rate improved steadily from 41.76% to 62.02%. Increased survival is closely related to birth weight (BW), regional economic development, and specialized hospital. The incidence of complications was neonatal respiratory distress syndrome (85.2%), oxygen dependency at 28 days (63.7%), retinopathy of prematurity (39.3%), intraventricular hemorrhage (29.4%), necrotizing enterocolitis (12.0%), and periventricular leukomalacia (8.0%). Among the 1156 nonsurvivors, 90.0% of infants died during the neonatal period (≤ 28 days). A total of 768 ELBW infants died after treatment withdrawal, for reasons of economic and/or poor outcome. The number of ELBW infants is increasing in Guangdong Province of China, and the overall survival rate is improving steadily.

Medicine - Abstract
Chronic inflammatory arthritis (CIA) severely impacts quality of life in over 100 million people in China. In 2011, the European League Against Rheumatism (EULAR) developed recommendations for the role of nurses in the management of CIA. However, it remains unknown whether these recommendations could be fully implemented in China. Therefore, we aimed to solve the problem in this study. We conducted a nationwide cross-sectional study among 485 nurses in rheumatology and immunology departments based on an online questionnaire. The agreement of the recommendations by the subjects and the feasibility of the recommendations they believe were assessed by visual analogue scale (VAS). Our results showed that over 80% of the subjects agreed with each recommendation (VAS 5–10), and over 80% of the subjects considered the recommendations feasible (VAS 5–10). This study indicates that the EULAR recommendations can also be well implemented in China.

BACKGROUND AND AIMS: EGFR activation and PKM2 expression are instrumental in tumorigenesis. EGFR activation regulates PKM2 functions in a subcellular compartment-dependent manner and promotes gene transcription and tumor growth. In addition, PKM2 is upregulated in EGFR-induced pathways in glioma malignancies. However, we found that PKM2 could also regulate the activity of the EGF/EGFR signaling pathway in gastric cancer cells. We aimed to define the biological mechanisms for PKM2 in regulating the cell motility and invasion. METHODS: We employed stable transfection with short hairpin RNA to stably silence the expression of PKM2 in the BGC823, SGC7901 and AGS gastric cancer cell lines. The effects of PKM2 in vitro were determined by assessing cell migration and invasion. Immunohistochemical analysis was used to explore the relationship among PKM2 and other proteins. RESULTS: Our results indicate that the knockdown of PKM2 decreased the activity of E-cadherin and enhanced the EGF/EGFR signaling pathway in the gastric cell lines BGC823 and SGC7901 that were positive for E-cadherin expression. However, in the undifferentiated gastric carcinoma cell line AGS, which lacks E-cadherin expression, PKM2 promoted cell migration and invasion. Immunohistochemical analyses showed that the levels of E-cadherin expression, ERK1/2 phosphorylation, and cytoplasmic PKM2 expression were correlated with each other. CONCLUSION: PKM2 may play different roles in differently differentiated gastric cancer cell types, and this finding would be consistent with the previous clinical research. The results of our study reveal an important link between PKM2 and E-cadherin during EGFR-stimulated gastric cancer cell motility and invasion.

Background Acute myeloid leukemia (AML) is a myeloid neoplasm accounts for 7.6% of hematopoietic malignancies. AML is a complex disease, and understanding its pathophysiology is contributing to the improvement in the treatment and prognosis of AML. In this study, we assessed the expression profile and molecular functions of CCAAT enhancer binding protein gamma (CEBPG), a gene implicated in myeloid differentiation and AML progression. Methods shRNA mediated gene interference was used to down-regulate the expression of CEBPG in AML cell lines, and knockdown efficiency was detected by RT-qPCR and western blotting. The effect of knockdown on the growth of AML cell lines was evaluated by CCK-8. Western blotting was used to detect PARP cleavage, and flow cytometry were used to determine the effect of knockdown on apoptosis of AML cells. Genes and pathways affected by knockdown of CEBPG were identified by gene expression analysis using RNA-seq. One of the genes affected by knockdown of CEBPG was Eukaryotic translation initiation factor 4E binding protein 1 (EIF4EBP1), a known repressor of translation. Knockdown of EIF4EBP1 was used to assess its potential role in AML progression downstream of CEBPG. Results We explored the ChIP-Seq data of AML cell lines and non-AML hematopoietic cells, and found CEBPG was activated through its distal enhancer in AML cell lines. Using the public transcriptomic dataset, the Cancer Cell Line Encyclopedia (CCLE) and western blotting, we also found CEBPG was overexpressed in AML. Moreover, we observed that CEBPG promotes AML cell proliferation by activating EIF4EBP1, thus contributing to the progression of AML. These findings indicate that CEBPG could act as a potential therapeutic target for AML patients. Conclusion In summary, we systematically explored the molecular characteristics of CEBPG in AML and identified CEBPG as a potential therapeutic target for AML patients. Our findings provide novel insights into the pathophysiology of AML and indicate a key role for CEBPG in promoting AML progression.

BACKGROUND Foreign bodies stuck in the throat and esophagus can be discharged through the digestive tract. Esophageal-lodged foreign bodies can cause secondary injury or detrimental response, with hepatic abscess being one such, albeit rare, outcome. Review and discussion of the few case reports on such instances will help to improve the overall understanding of such conditions and aid in differential diagnosis to improve patient outcome. CASE SUMMARY A 51-year-old female patient with pre-existing diabetes visited our hospital following a 15-d experience of chills and fever. Both plain and enhanced magnetic resonance imaging and color Doppler ultrasound examination of the liver and gallbladder revealed a space-occupying lesion in the caudate lobe of the liver (7.8 cm × 6.0 cm × 5.0 cm). Initially, a malignant tumor was suspected, but differential diagnosis was unable to exclude the possibility of hepatic abscess. Conservative anti-infection therapy produced a less than ideal outcome. Additional examination by hepatobiliary imaging with computed tomography suggested a foreign body present in the upper abdomen and hepatic abscess, and subsequent endoscopy revealed a sinus tract in the anterior wall of the duodenal bulb. Therefore, surgery was performed to remove the object (fishbone) and drain the abscess. After a 2-wk uneventful recovery, the patient was discharged. The final diagnosis was foreign body-induced hepatic abscess of the caudate lobe. CONCLUSION Differential diagnosis is important for hepatic masses, and systematic examination and physician awareness can aid in diagnosing and curing such rare conditions.

Background Mounting evidence shows that microRNA-34a (miR-34a) is involved in cancer prognosis. Therefore, we summarize the predictive role of miR-34a for survival in patients with gastrointestinal cancers (GICs). Methods All eligible studies were found by searching PubMed, Web of Science and EMBASE, and survival results were extracted. Then, the hazard ratio (HR) with the corresponding 95% confidence interval (CI) was calculated to evaluate the prognostic role of miR-34a in GICs. The association between miR-34a expression and clinicopathological characteristics was estimated by odds ratios (ORs) and 95% CIs. Results A total of 20 studies were included in this meta-analysis. For overall survival (OS), lower miR-34a expression could probably predict poorer outcome in GICs, with a pooled HR of 1.86 (95% CI: 1.52–2.28, P P Conclusion This meta-analysis revealed that lower miR-34a expression is significantly connected with worse OS and DFS/PFS/RFS in GIC patients. In addition, the miR-34a expression level is relatively lower in patients with lymph node metastasis than in patients without lymph node metastasis, and decreased miR-34a expression levels are linked to poor tumour differentiation and late TNM stage. MiR-34a may become a new factor for the prognosis prediction and progression of GICs.

Epidemiological studies on the association of sulfur dioxide (SO2) with neural tube defects (NTDs) are lacking. The purpose of this study was to assess the aforementioned association through a population-based case–control study. This study involved 1457 NTDs cases and 7950 randomly selected healthy infants born in 14 cities in Liaoning province between 2010 and 2015. Ambient SO2 levels were acquired from 75 monitoring stations. The exposure assessment was based on the mean concentration of all stations in mother’s residential city. We used logistic regression models to assess the associations. In multivariable models adjusted for the confounding variables selected based on the 10 percent change-in-estimate method, we found that maternal SO2 exposure was positively associated with an increased risk of NTDs during the first month after conception (per 10 μg/m3 increase: adjusted odds ratio [aOR] = 1.02, 95% confidence interval [CI]: 1.00–1.04; highest versus lowest quartile: aOR = 2.55, 95% CI: 1.97–3.31) and the second month after conception (per 10 μg/m3 increase: aOR = 1.02, 95% CI: 1.00–1.04; highest versus lowest quartile: aOR=2.31, 95% CI: 1.77–3.00). For other exposure windows, positive associations also emerged in high- versus low-exposure analyses, except for the third month before conception; however, we could not further confirm significant findings from the continuous exposure analyses. Our study provides a new evidence that SO2 exposure may increase the risk of NTDs.

Bromodomain (BRD)-containing proteins are a class of epigenetic readers with unique recognition for N-acetyl-lysine in histones and functions of gene transcription and chromatin modification, known to be critical in various cancers. However, little is known about the roles of distinct BRD-containing protein genes in hepatocellular carcinoma (HCC). Most recently, we investigated the transcriptional and survival data of BRD1, BRD2, BRD3, BRD4, BRD7, BRD8, BRD9 in HCC patients through ONCOMINE, UALCAN, Human Protein Atlas, GEPIA, cBioPortal, STRING, TIMER databases. BRD1/2/3/4/7/8/9 were over-expressed in HCC and were significantly associated with clinical cancer stages and pathological tumor grades. High mRNA expressions of BRD4/8/9 were promising candidate biomarkers in HCC patients. The rate of sequence alternations in BRD1/2/3/4/7/8/9 was relatively high (52%) in HCC patients, and the genetic alternations were correlated with shorter overall survival and disease-free survival in HCC patients. Additionally, the mRNA expression levels of individual BRD genes were significantly positively associated with the immune infiltrating levels of B cells, CD8+ T cells, CD4+ T cells, macrophages, neutrophils, and dendritic cells. And the associations between BRD1/2/3/4/7/8/9 and diverse immune marker sets showed a significance. Overall, these results indicated that BRD4/8/9 could be potential prognostic markers and druggable epigenetic targets in HCC patients.

BackgroundCurrent literature describes limited and controversial evidence on the associations between maternal preconception and first trimester exposure to particulate matter with a diameter ≤10 µm (PM10) and the risk of oral cleft (OC).MethodsWe conducted a case–control study involving 3086 OC cases and 7950 controls, registered in the Maternal and Child Health Certificate Registry in Liaoning Province between 2010 and 2015. PM10 concentrations were obtained from the Environment Protection Bureau. The exposure windows included the 3 months before pregnancy, the first trimester and the individual months. Unconditional logistic regression model was performed to estimate the OR and 95% CI for the association between PM10 exposure and the risk of OC, cleft lip only (CLO), cleft palate only (CPO), and cleft lip and palate (CLP).ResultsMaternal PM10 exposure was positively associated with an increased risk for OC during the 3 months preconception (per 10 µg/m3 increment: OR=1.04, 95% CI 1.01 to 1.07; highest vs lowest quartile: OR=1.23, 95% CI 1.04 to 1.45) and the first trimester (per 10 µg/m3 increment: OR=1.05, 95% CI 1.02 to 1.08; highest vs lowest quartile: OR=1.37, 95% CI 1.15 to 1.64). Analyses based on individual months presented similar positive associations, particularly in the second month of pregnancy (OR=1.77, 95% CI 1.51 to 2.09) for highest versus lowest quartile. In the subtype analysis, stronger associations were observed for CLO, whereas there was negligible evidence for CPO and CLP. Sensitivity analyses using propensity score matching generated similar findings.ConclusionsOur study provides evidence that PM10 exposure during the 3 months preconception and the first trimester increases the risk of OC.

Background/Aims Pancreatic ductal adenocarcinoma (PDAC) is associated with high mortality, even after surgical resection. The existing predictive models for survival have limitations. This study aimed to develop better nomograms for predicting overall survival (OS) and cancer‐specific survival (CSS) in PDAC patients after surgery. Methods A total of 6323 PDAC patients were retrospectively recruited from the Surveillance, Epidemiology, and End Results (SEER) database and randomly allocated into training, validation, and test cohorts. Multivariate Cox regression analysis was conducted to identify significant independent factors for OS and CSS, which were used for construction of nomograms. The performance was evaluated, validated, and compared with that of the 8th edition AJCC staging system. Results Ten independent factors were significantly correlated with OS and CSS. The 1‐, 3‐, and 5‐year OS rates were 40%, 20%, and 15%, and 1‐, 3‐, and 5‐year CSS rates were 45%, 24%, and 19%, respectively. The nomograms were calibrated well, with c‐indexes of 0.640 for OS and 0.643 for CSS, respectively. Notably, relative to the 8th edition AJCC staging system, the nomograms were able to stratify each AJCC stage into three prognostic subgroups for more robust risk stratification. Furthermore, the nomograms achieved significant clinical validity, exhibiting wide threshold probabilities and high net benefit. Performance assessment also showed high predictive accuracy and reliability. Conclusions The predictive ability and reliability of the established nomograms have been validated, and therefore, these nomograms hold potential as novel approaches to predicting survival and assessing survival risks for PDAC patients after surgery., In the present study, we constructed and validated nomograms for predicting the 1‐, 3‐, and 5‐year OS and CSS rates after surgical resection of PDAC. The nomograms established in the present study showed good performance for the prediction of OS and CSS, which was superior to that of the existing, conventional AJCC staging system with an improved net benefit. Therefore, these nomograms hold promise as novel prognosis models for improving the prediction of individualized postoperative survival and improving the care of PDAC patients following surgical resection.

Background With the increase in extremely low birth weight (ELBW) infants, their outcomes received special attention. However, in China, studies of the outcomes of ELBW infants are rare. Methods The hospitalized records of ELBW infants discharged from twenty-six neonatal intensive care units were reviewed and analyzed. Results A total of 2575 ELBW infants were enrolled and the overall survival rate was 55.11%. From 2008 to 2017, the number of ELBW infants increased rapidly from 91 to 466, and the survival rate improved steadily from 41.76–62.02%. The survival rate rose with increasing BW, the ascending level of regional economic development and specialist hospitals. The incidence of complications was neonatal respiratory distress syndrome (85.2%), bronchopulmonary dysplasia (63.7%), retinopathy of prematurity (39.3%), intraventricular hemorrhage (29.4%), necrotizing enterocolitis (12.0%), and periventricular leukomalacia (8.0%). Among the 1156 nonsurvivors, 90.0% of infants died during the neonatal period (≤ 28 days), and the other died after the neonatal period. A total of 768 ELBW infants died after medical care withdrawal, with economic factors and expected outcome being important causes. Conclusion The number of ELBW infants is increasing in China, and the overall survival rate is still low but is improving steadily.

Background Gallbladder carcinoma (GBC) was the most common malignancy of biliary tract. Patients with malignancies frequently present with activated coagulation pathways, which might potentially related to tumor progression and prognosis. The purpose of the study was to investigate the clinical significance of preoperative serum fibrinogen levels and platelet counts in GBC patients. Methods The preoperative fasting serum fibrinogen levels and platelet counts of 58 patients with GBC were measured by AUV2700 automatic biochemical analyzer, as well as 60 patients with cholesterol polyps and 60 healthy volunteers. Kaplan–Meier survival analysis was applied to show the correction between fibrinogen levels and outcome after surgery. Results The fibrinogen levels of patients with GBC were significantly higher than healthy gallbladder and cholesterol polyp of gallbladder (p 0.05) in multivariate analysis. Conclusions The preoperative serum fibrinogen levels and platelet counts might be reliable biomarkers for the occurance of disease, tumor depth, lymph node metastasis, distant metastasis and advanced TNM stage in patients with GBC. The serum fibrinogen levels might be a prognostic factor to predict outcome for GBC patients suffering from surgery treatment. Anticoagulation therapy might be considered to control cancer progression in future studies.

Limited studies have focused on the impact of ambient air pollution on spina bifida. A population-based case-control study was conducted in Liaoning Province, China to assess the associations between maternal PM10 exposures in various exposure windows and spina bifida risk. Data on spina bifida cases born between 2010 and 2015 were available from the Maternal and Child Health Certificate Registry of Liaoning Province. Controls were a random sample of healthy livebirths without any birth defects delivered in the selected five cities during 2010–2015. Ambient air monitoring data for PM10 were obtained from 75 monitoring stations in Liaoning Province. The multivariable logistic regression models were established to calculate adjusted odds ratios (OR) and 95% confidence intervals (CI). We further performed sensitivity analyses by using three propensity score methods. A total of 749 spina bifida cases and 7,950 controls were included. After adjusting for potential confounders, spina bifida was associated with a 10 μg/m3 increment in PM10 during the first trimester of pregnancy (adjusted OR = 1.06, 95% CI: 1.00–1.12) and the 3 months before pregnancy (adjusted OR = 1.12, 95% CI: 1.06–1.19). The adjusted ORs in the final model for the highest vs. the lowest quartile were 1.51 (95% CI: 1.04–2.19) for PM10 during the first trimester of pregnancy and 2.01 (95% CI: 1.43–2.81) for PM10 during the 3 months before pregnancy. Positive associations were found between PM10 exposures during the single month exposure windows and spina bifida. Sensitivity analyses based on two propensity score methods largely reported similar positive associations. Our findings support the evidence that maternal PM10 exposure increases the risk of spina bifida in offspring. Further, validation with a prospective design and a more accurate exposure assessment is warranted.

As far as we know, there have been no studies exploring the association between maternal sulfur dioxide (SO2 ) exposure and the risk of hypospadias in offspring. We aimed to evaluate this association during the 3 months before conception and the first trimester. A population-based case-control study was conducted in male infants, consisting of 348 cases of hypospadias and 4023 controls. Maternal exposure to SO2 , particulate matter with aerodynamic diameters ≤10 μm (PM10 ), and nitrogen dioxide (NO2 ) was assessed by averaging the concentrations recorded at all stations in the mother's city of residence. Air pollutants were tested for multicollinearity using variance inflation factor analysis. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by multivariable logistic regression models. SO2 exposure during the 3 months before conception was significantly associated with the risk of hypospadias (highest tertile: OR = 7.40, 95% CI: 3.54-15.62). When focusing on shorter exposure windows, similar associations were observed for SO2 exposure in the first and second month before and the first month after conception. In conclusion, maternal exposure to SO2 during the 3 months before and the first and second months after conception may increase the risk of hypospadias in offspring.

Background: The potential association between maternal exposure to PM10 ranging from 3 months prior to conception to the end of the early trimester and the risk of anorectal atresia/stenosis in offspring have not been established. Thus, we determined the association in this study.Methods: We recruited 713 patients with anorectal atresia/stenosis and 7950 randomly selected healthy offspring from the Maternal and Child Health Certificate Registry of Liaoning Province and delivered between 1 January 2010 and 31 December 2015. Monthly PM10 concentrations were retrieved from the Environment Protection Bureau of each city in Liaoning Province. We established a multivariable logistic regression model to calculate the adjusted odds ratios (ORs) and 95% confidence intervals (CIs).Results: Maternal exposure to PM10 was associated with an increased risk for anorectal atresia/stenosis in offspring during the three months prior to conception (per 10 μg/m3 increment: OR = 1.15, 95% CI = 1.03–1.20; per SD [27 μg/m3] increment: OR = 1.33, 95% CI = 1.09–1.63) and the first trimester (per 10 μg/m3 increment: OR = 1.08, 95% CI = 1.00–1.17; per SD [28 μg/m3] increment: OR = 1.26, 95% CI = 1.01–1.57). Evaluation of the association with a shorter exposure window (1 month) revealed a positive association between anorectal atresia/stenosis and PM10 from the 3rd month prior to pregnancy to each month of the 1st trimester.Conclusion: Maternal exposure to PM10 three months prior to conception and during the 1st trimester was associated with and increased risk of anorectal atresia/stenosis in the offspring. Future perspective studies are needed to confirm our findings.

Purpose Primary hepatic angiosarcoma is a very rare and highly malignant tumor with poor prognosis. It is difficult to diagnose because of the lack of typical clinical features, and the treatment protocols for PHA are also not clear. Therefore, this study wants to find out the clinical characteristics and surgical treatments of primary hepatic angiosarcoma. Methods Among 8990 patients diagnosed with primary malignant tumor of the liver from January 2000 to December 2019 in our hospital, only four patients were diagnosed with primary hepatic angiosarcoma. The demographics, clinical manifestation, past history, serology test results, MRI features, pathology, treatment modality and prognosis of four patients were collected and analyzed. Results Three of four patients had no clinical symptoms, while one patient's symptom was abdominal pain. The levels of tumor markers of all four patients were within the normal reference range and serological tests were negative for hepatitis B and C virus. The MRI imaging findings of all four patients were mixed mass with highly disordered vascular characteristics. All four patients were misdiagnosed preoperatively. One patient who underwent hepatic lobectomy was still alive for about 18 months after surgery. One patient who underwent hepatic lobectomy has survived for only 6 months due to severe pneumonia. The other two patients who received transarterial chemoembolization survived 16 months and 11 months respectively. Conclusion The clinical symptoms of primary hepatic angiosarcoma are not typical, and primary hepatic angiosarcoma is easily misdiagnosed. The typical imaging manifestations are structural disorder and heterogeneous tumor. Hepatic lobectomy and transarterial chemoembolization may be important surgical treatments to improve the prognosis of patients.

Background/AimsPancreatic ductal adenocarcinoma (PDAC) can occur in different parts of the pancreas. This study aimed to identify clinicopathological characteristics independently correlated with the prognosis of PDAC of the pancreatic head/uncinate (PHC) or body-tail (PBTC), and to develop novel nomograms for predicting cancer-specific survival (CSS) according to different primary cancer locations.Methods1160 PDAC patients were retrospectively enrolled and assigned to training and test sets with each set divided into PHC and PBTC groups. Comparative analysis of clinicopathologic characteristics, survival analysis, and multivariate analysis were performed. Independent factors were identified and used for constructing nomograms. The performance of the nomograms was validated in the test set.ResultsPrimary tumor location was an independent risk factor for prognosis of PDAC after surgery. Specially, gender, fasting blood glucose, and preoperative cancer antigen 19-9 were significantly associated with prognosis of PHC, whereas age, body mass index, and lymph nodes were significantly correlated with the prognosis of PBTC. A significant difference in prognosis was found between PHC and PBTC in stage Ia and stage III. Three nomograms were established for predicting the prognosis for PDAC, PHC, and PBTC. Notably, these nomograms were calibrated modestly (c-indexes of 0.690 for PDAC, 0.669 for PHC, and 0.704 for PBTC), presented better accuracy and reliability than the 8th AJCC staging system, and achieved clinical validity.ConclusionsPHC and PBTC share the differential clinical-pathological characteristics and survival. The nomograms show good performance for predicting prognosis in PHC and PBTC. Therefore, these nomograms hold potential as novel approaches for predicting survival of PHC and PBTC patients after surgery.

Airway stenosis is a common problem in the neonatal intensive care unit (NICU) and pediatric intensive care unit (PICU). A tissue-engineered trachea is a new therapeutic method and a research hotspot. Successful vascularization is the key to the application of a tissue-engineered trachea. However, successful vascularization studies lack a complete description. In this study, it was assumed that rabbit bone marrow mesenchymal stem cells were obtained and induced by ascorbic acid to detect the tissue structure, ultrastructure, and gene expression of the extracellular matrix. A vascular endothelial cell culture medium was added in vitro to induce the vascularization of the stem cell sheet (SCS), and the immunohistochemistry and gene expression of vascular endothelial cell markers were detected. At the same time, vascular growth-related factors were added and detected during SCS construction. After the SCS and decellularized tracheal (DT) were constructed, a tetrandrine allograft was performed to observe its vascularization potential. We established the architecture and identified rabbit bone marrow mesenchymal stem cell membranes by 14 days of ascorbic acid, studied the role of a vascularized membrane in inducing bone marrow mesenchymal stem cells by in vitro ascorbic acid, and assessed the role of combining the stem cell membranes and noncellular tracheal scaffolds in vivo. Fourteen experiments confirmed that cell membranes promote angiogenesis at gene level. The results of 21-day in vitro experiments showed that the composite tissue-engineered trachea had strong angiogenesis. In vivo experiments show that a composite tissue-engineered trachea has strong potential for angiogenesis. It promotes the understanding of diseases of airway stenosis and tissue-engineered tracheal regeneration in newborns and small infants.

Background T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive disease with a high risk of induction failure and poor outcomes, with relapse due to drug resistance. Recent studies show that bromodomains and extra-terminal (BET) protein inhibitors are promising anti-cancer agents. ARV-825, comprising a BET inhibitor conjugated with cereblon ligand, was recently developed to attenuate the growth of multiple tumors in vitro and in vivo. However, the functional and molecular mechanisms of ARV-825 in T-ALL remain unclear. This study aimed to investigate the therapeutic efficacy and potential mechanism of ARV-825 in T-ALL. Methods Expression of the BRD4 were determined in pediatric T-ALL samples and differential gene expression after ARV-825 treatment was explored by RNA-seq and quantitative reverse transcription-polymerase chain reaction. T-ALL cell viability was measured by CCK8 assay after ARV-825 administration. Cell cycle was analyzed by propidium iodide (PI) staining and apoptosis was assessed by Annexin V/PI staining. BRD4, BRD3 and BRD2 proteins were detected by western blot in cells treated with ARV-825. The effect of ARV-825 on T-ALL cells was analyzed in vivo. The functional and molecular pathways involved in ARV-825 treatment of T-ALL were verified by western blot and chromatin immunoprecipitation (ChIP). Results BRD4 expression was higher in pediatric T-ALL samples compared with T-cells from healthy donors. High BRD4 expression indicated a poor outcome. ARV-825 suppressed cell proliferation in vitro by arresting the cell cycle and inducing apoptosis, with elevated poly-ADP ribose polymerase and cleaved caspase 3. BRD4, BRD3, and BRD2 were degraded in line with reduced cereblon expression in T-ALL cells. ARV-825 had a lower IC50 in T-ALL cells compared with JQ1, dBET1 and OTX015. ARV-825 perturbed the H3K27Ac-Myc pathway and reduced c-Myc protein levels in T-ALL cells according to RNA-seq and ChIP. In the T-ALL xenograft model, ARV-825 significantly reduced tumor growth and led to the dysregulation of Ki67 and cleaved caspase 3. Moreover, ARV-825 inhibited cell proliferation by depleting BET and c-Myc proteins in vitro and in vivo. Conclusions BRD4 indicates a poor prognosis in T-ALL. The BRD4 degrader ARV-825 can effectively suppress the proliferation and promote apoptosis of T-ALL cells via BET protein depletion and c-Myc inhibition, thus providing a new strategy for the treatment of T-ALL.

Background: Mounting evidence shows that microRNA-34a (miR-34a) is involved in cancer prognosis. Therefore, we summarize the predictive role of miR-34a for survival in patients with gastrointestinal cancers (GICs). Methods: All the eligible studies were searched by PubMed, Web of Science and EMBASE and survival results were extracted. Then, the hazard ratio (HR) with corresponding 95% confidence intervals (CIs) was calculated to evaluate the prognostic role of miR-34a in GICs. The association between miR-34a expression and clinicopathological characteristics was estimated by odds ratio (OR) and 95%CIs. Results: A total of 20 studies were included in this meta-analysis. For overall survival (OS), the lower miR-34a expression significantly predicted poorer outcome in GICs, with the pooled HR of 1.86 (95% CI: 1.52-2.28, P

Background: The minichromosome maintenance protein 10 (MCM10) is a replication licensing factor that initiates eukaryotic genome replication by interacting with CDC45-MCM2-7 complex, thereby mediating cellular proliferation. Recent studies have found that MCM10 is involved in tumorigenesis and cancer development. However, research on the role of MCM10 in hepatocellular carcinoma (HCC) is scarce.Methods: In this study, the transcriptional expression, prognostic efficacy and function of MCM10 in HCC were explored through the public dadabases and bioinformatic tools, including ONCOMINE, Kaplan-Meier plotter, cBioPortal, TIMER and GEPIA. Statistical significance was inferred at a P-value < 0.05.Results: It was found that MCM10 expression was commonly overexpressed in cancer specimens compared to match normal tissues. Up-regulation of MCM10 gene in HCC had a close relationship with patients’ survival time. A higher level of MCM10 expression was correlated with shorter overall survival (OS) and progression-free survival (PFS) in HCC patients, especially at early stages (grade 2 or stage 1+2). MCM10 was also demonstrated to be an independent negative predictor of OS and disease-free survival (DFS) in patients with HCC by multivariate Cox regression. Additionally, according to the levels of marker genes for different immune cells in HCC, MCM10 expression was markedly positively correlated with the numbers of tumor-infiltrating B cells, CD8+ T cells, CD4+ T cells, macrophages, neutrophils and dendritic cells, indicating its potential immunogenic role in HCC. Conclusions: MCM10 could be exploited as a potential independent prognostic indicator as well as therapeutic target for HCC patients.

Percutaneous ethanol injection is a well-known ablation therapy for hepatocellular carcinoma and is well-tolerated, inexpensive, and effective with few adverse events. In this study, another type of ethanol injection was introduced in the present study. Sixty two patients with hepatocellular carcinoma received 133 percutaneous peritumor ethanol injection treatments and the 15-year follow-up outcomes were analyzed through a collected database. The technical efficiency was 89.5% (119/133 treatments) after the first percutaneous peritumor ethanol injection procedure. However, after the second repeated percutaneous peritumor ethanol injection procedure, technical efficiency increased to 98.5% (131/133 treatments). The 1 year, 3 years, 5 years, 10 years, and 15 years rates of tumor recurrence were 12.9%, 50.0%, 59.7%, 74.2%, and 74.2%, respectively. Multivariate analysis demonstrated that diabetes, Child–Pugh class B, and tumor size greater than 2 cm were significantly related to tumor recurrence. The 1 year, 3 years, 5 years, 10 years, and 15 years rates of overall survival were 98.4%, 83.6%, 61.3%, 19.4%, and 0%, respectively. Multivariate analysis demonstrated that Child–Pugh class B, tumor size greater than 2 cm, and multiple tumors were significantly related to overall survival. Compared with other ablation methods (including peritumor ethanol injection), percutaneous peritumor ethanol injection can avoid tumor ruptures, reduce tumor proliferation and metastasis, and is suitable for the treatment of small tumors. In addition, when combined with other treatment methods, percutaneous peritumor ethanol injection can form a tumor metastatic isolation zone in advance and improve the comprehensive treatment effect.

Systemic inflammation and interactions with host-tumor are currently identified as a hallmark of cancer. The purpose of this study was to assess the prognostic value of preoperative modified Glasgow Prognostic Score (mGPS), systemic inflammation score (SIS) and "lymphocyte C-reactive protein score" (LCS) in gastric cancer (GC) patients.358 GC patients were enrolled in this retrospective study. Kaplan-Meier method, multivariate Cox regression analysis, time-dependent receiver operating characteristics analysis (ROC), concordance index (C-index), and Akaike information criterion (AIC) were applied for assessments of the prognostic values.Preoperative increased mGPS, SIS and LCS were all significantly linked with unfavorable overall survival using the Kaplan-Meier method (P 0.001). Multivariate analysis proved that SIS was the only independent indicator among these three scoring systems. At the 4th-month point postoperatively, the time-dependent ROC curves of SIS and LCS crossed the curve of mGPS and were consistently superior to that of mGPS thereafter. The model incorporating SIS had higher C-index and smaller AIC than did the model without SIS or the models with mGPS or LCS.Preoperative SIS exceeded both the mGPS and LCS and was the most clinically promising and feasible prognostic scoring system for GC patients.

Background There is no epidemiological evidence on the effects of maternal exposure to ambient particulate matter 10 μm or less in diameter (PM10) and anencephaly risk in offspring. Methods We conducted a population-based case-control study in Liaoning Province, China. The case group consisted of 663 cases with anencephaly and the control group consisted of 7950 healthy infants from the Maternal and Child Health Certificate Registry of Liaoning Province that were born between 2010 and 2015. Daily PM10 concentrations were obtained from 77 monitoring stations located within the study area. A multivariable logistic regression model was established to calculate the adjusted odds ratios (ORs) and 95% confidence intervals (CIs). Results Maternal PM10 exposure was significantly associated with an increased risk of anencephaly at three months before conception (highest versus lowest tertile: OR = 1.74, 95% CI: 1.29–2.34; per 10 μg/m3 increment: OR = 1.13, 95% CI: 1.06–1.20) and three months after conception (highest versus lowest tertile: OR = 1.93, 95% CI: 1.44–2.60; per 10 μg/m3 increment: OR = 1.01, 95% CI: 0.95–1.08). The evaluation of shorter exposure windows revealed similar associations for PM10 exposure from the third month before pregnancy to the third month after pregnancy. Conclusions Maternal PM10 exposure is positively associated with anencephaly risk during the critical period of neural system development.

The aim of this study was to assess the prevalence and trends of congenital hydrocephalus (CH) using a large population-based sample with cases retrieved from the Liaoning Birth Defects Registry, which included 14 cities, over a 10-year period. CH prevalence, percent change, average change, and contribution rates of each city were calculated. Statistical analysis was performed using a Poisson regression model. There was a total of 3008 CH cases among 3,248,954 live births during the observational period (9.26 cases/10,000 live births). On average, the prevalence of CH had significantly decreased by 11.84% each year (P < 0.01). The three leading cities with the highest prevalence of CH were Chaoyang (13.73/10,000), Huludao (13.18/10,000), and Fuxin (12.71/10,000), while Yingkou (6.06/10,000), Dalian (6.27/10,000), and Anshan (6.56/10,000) had the lowest prevalence. Notably, significantly decreasing trends were observed in 10 (71.4%) of these 14 cities. In addition, the cities of Fushun, Shenyang, and Dalian had contributed to more than one-third of the decreasing trend in Liaoning province. In conclusion, this study provides evidence of the decreasing prevalence of CH over a 10-year period (2006–2015) in Liaoning province. Preventative efforts should be strengthened to further reduce the risk of CH in these high prevalence areas.

Nitrogen oxide (NOx) is produced during combustion at high temperature, which is a major constituent of air pollutants. Recent studies suggested inconsistent results on the association between NOx exposure and cardiovascular-related malformations. We aimed to assess aforementioned association in pregnant women in the first trimester and cardiovascular-related malformations of infants. A systematic literature review identified studies for observational studies about NOx exposure and cardiovascular-related malformation in PubMed. Random-effect models were used to estimate summary odds ratio (SOR) and 95% confidence intervals (CIs) for aforementioned association. Finally, nine studies met the inclusion criteria. Overall, the SOR of cardiovascular-related malformation per 10 ppb increment in NOx and NO2 concentration was 1.01 (95% CI: 0.98–1.04; I2 = 38.6%, P=0.09) and 0.99 (95% CI: 0.95–1.04; I2 = 37.8%, P=0.13), respectively. Stratifying by study design, geographic locations, and confounded adjustments, the majority of strata showed negative results, which were consistent with the main findings. However, we found that exposure to NOx and NO2 in the first trimester increased the risk of coarctation of the aorta (COA) malformation by 13% and 19%, respectively. Our study provided limited evidence regarding the association between NOx exposure in the first trimester and cardiovascular-related malformations in infants.

The prognosis of patients with intrahepatic cholangiocarcinoma (ICC) is undefined among the different macroscopic types. This study evaluated the viability of the American Joint Committee on Cancer (AJCC) 8th edition staging classification for different macroscopic types. Utilizing the Surveillance, Epidemiology, and End Results (SEER) database, we enrolled a total of 2,679 eligible patients with an estimated 199 periductal infiltrating type of ICC (ICC-PI) patients and 2,480 mass-forming type of ICC (ICC-MF) patients. After conducting a multivariate Cox analysis, we found that the AJCC 8th edition staging system was suitable for ICC-MF patients but not for ICC-PI patients according to cancer-specific survival (CSS) and overall survival (OS). The main reason was the similar hazard ratio (HR) between the ICC-PI patients with stage I and stage II disease according to CSS (HR:0.969, P = 0.949) and OS (HR:0.832, P = 0.703). Moreover, we found that ICC-PI patients in AJCC stage I had a similar HR as ICC-MF patients in AJCC stage II according to CSS (HR: 1.208, P = 0.475) and OS (HR:1.206, P = 0.456). Therefore, we suggested that ICC-PI patients may be defined as T2, which is classified as stage II disease. This suggestion for the AJCC 8th edition staging system would be more suitable for different macroscopic types of ICC but requires further verification in prospective clinical trials.

Background Cross-border malaria transmission in China is a major component of Chinese imported malaria cases. Such cases mostly are travellers returning from malaria endemic countries in Africa. By investigating malaria infectious status among Chinese worker in Africa, this study analysed the malaria risk factors, in order to establish infectious forecast model. Methods Chinese returnees data from Africa were collected at Guangzhou Baiyun International Airport, Guangzhou, China between August 2015 and March 2016 and were included in the cross-sectional and retrospective survey. Results A total of 1492 respondents were included in the study with the majority consisting of junior middle school educated male. Most of them are manual and technical workers hired by companies, with average of 37.04 years of age. Overall malaria incidence rate of the population was 8.98% (134/1492), and there were no significant differences regarding age, gender, occupation, or team. Forecast model was developed on the basis of malaria risk factors including working country, local ecological environment type, work duration and intensity of mosquito bite prevention. Conclusions The survey suggested that malaria incidence was high among Chinese travellers who had worked in Africa countries of heavy malaria burden. Further research on the frequency and severity of clinical episodes among Chinese travellers having worked in Africa is needed.

We calculated the prevalence of spina bifida, percent and average change of time trends, and contribution rates of each city. Poisson regression model was used to find the line of best fit for spina bifida prevalence by year, with year as a continuous independent variable. From 2006 to 2015, a total of 2,029 spina bifida cases were identified from 3,248,954 live births (6.25/10,000 live births). We observed statistically significant decreasing trend of overall time trend (11.57% each year). Chaoyang, Fuxin, and Huludao were the top three leading cities, with 14.30/10,000 live births, 9.70/10,000 live births, and 9.20/10,000 live births, respectively. Inversely, the bottom three cities with lowest prevalence were Anshan (2.64/10,000 live births), Dandong (3.43/10,000 live births), and Dalian (3.45/10,000 live births). Of note, we observed significant decreasing trends in over half of these cities ( n = 8). In addition, the decreasing trend of overall time trend could be mainly attributed to cities of Shenyang, Fushun, and Jinzhou which accounted for nearly one third. In summary, our study suggested a decreasing time trend of spina bifida during the past decade in the Liaoning province. The findings of this study provide evidence that the nationwide folic acid supplement program has been an effective strategy to prevent spina bifida.

Background The number of studies on air pollution with birth defects as the primary outcome has increased dramatically over the past two decades, but the potential role of specific air pollutants in congenital limb anomalies remains unclear. Objectives To evaluate associations between preconception and first-trimester PM10 exposure and polydactyly and syndactyly in a population-based case-control study. Methods Polydactyly cases (n = 2605), syndactyly cases (n = 595), and controls without any birth defects (n = 7950) born between 2010 and 2015 were selected from the Maternal and Child Health Certificate Registry of Liaoning Province. The monthly mean PM10 concentrations were obtained from 75 air monitoring stations, and the exposure assessment was based on the mean concentration of all stations in mother's residential city. A multivariable logistic regression model was constructed to calculate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). Results PM10 exposure was positively associated with the risks of polydactyly (preconception: aORT3 vs. T1 = 1.95, 95% CI 1.56–2.45, aOR = 1.06, 95% CI 1.01–1.10 [per 10-μg/m3 increment]; first-trimester: aORT3 vs. T1 = 2.51, 95% CI 2.00–3.15) and syndactyly (preconception: aORT3 vs. T1 = 2.86, 95% CI 1.98–4.13, aOR = 1.11, 95% CI 1.03–1.20 [per 10-μg/m3 increment]; first-trimester: aORT3 vs. T1 = 3.10, 95% CI 2.11–4.56). Analyses based on single month exposure windows basically showed similar positive associations. Additionally, these findings were robust in sensitivity analyses and broadly consistent across subgroups. Conclusion Our study suggest that preconception and first-trimester PM10 exposures are related to increased risks of polydactyly and syndactyly.

Background The potential association between maternal exposure to ambient PM10 and offspring neural tube defects (NTDs) is a contentious issue. This study aims to evaluate the aforementioned association at a provincial level in China. Methods A total of 2736 cases and 7950 randomly selected healthy infants included in the Maternal and Child Health Certificate Registry of Liaoning Province and delivered between 2010 and 2015 were recruited. Daily PM10 concentrations were obtained from all available monitoring stations located within the study area. A multivariable logistic regression model was established to calculate the adjusted odds ratios (ORs) and 95% confidence intervals (CIs). Results PM10 exposure was significantly associated with the risk of NTDs during the three months preconception (per 10 μg/m3 increment: OR = 1.10, 95% CI 1.07–1.14; per standard deviation [27 μg/m3] increment: OR = 1.29, 95% CI 1.18–1.41; highest tertile: OR = 1.61, 95% CI 1.37–1.91) and the first trimester (highest tertile: OR = 1.57, 95% CI: 1.31–1.87). When focusing on shorter exposure windows, similar associations were observed for PM10 exposure from the third month before pregnancy to the third month after pregnancy. Sensitivity analyses using propensity score matching yielded consistent findings. Conclusions Maternal exposure to PM10 is positively associated with NTDs during the critical period of fetal neural tube development. However, due to the limitation of the exposure assessment as well as potential residual confounding, further research is warranted to confirm our findings.

Breast cancer is one of the most common cancers in women around the world. In Taiwan, the number of women suffering from breast cancer is increasing year by year. Furthermore, the incidence rate and mortality rate of breast cancer in women were ranked first and fourth, respectively, but its free screening rate had the lowest proportion of mammography examination usage. That statistic is due to the breasts being a very private part of the body and women being unlikely to get the screening done due to social perceptions and poor awareness of the disease. Therefore, the ideal timing for getting early treatment is often missed. This study was initiated to collect the perceptions of the general public about breast cancer screening by way of the comments and replies to any query or experience sharing left on different social media websites (PTT, Mobile01, and Facebook). Using the text mining technique to catch important features and connect them to different personalities of people, the identification model can be established by CART (Classification and Regression Tree) machine learning. The model will then be applied to explore the lifestyles and personalities of those people concerned about breast cancer screening so that different prevention and management policies can be proposed to meet their different needs. The study experiment example was based on gender identification to proceed with the model simulation and forecast accuracy.

Background: Chronic inflammatory arthritis(CIA) is considered the leading cause of disability that places severe limits on daily activity and quality of life for over 100 million Chinese. Nurse-led CIA management reveals tremendous benefits for CIA patients. European League Against Rheumatism(EULAR) developed the recommendations for the role of the nurse in the management of CIA in 2011, however, whether or not the recommendations could be fully implemented in China is unknown. Objectives: The aim was to test the EULAR recommendations among registered Chinese rheumatology nurses in terms of its agreement level, practicality, and adverse conditions to the implementation. Methods: We conducted an anonymous online questionnaire among registered clinical nurses in the department of rheumatology and immunology nationwide based on convenience sampling. The agreement and feasibility of the recommendations were assessed by visual analogue scale(VAS 0=total disagreement/completely infeasible, VAS 1–4=partial disagreement/partially infeasible, VAS 5–9=partial agreement/partially feasible, VAS 10=complete agreement/completely feasible). The respondents needed to select the reasons they agreed or disagreed and if they thought the recommendations were feasible or not. Results: 485 subjects were included, and 438 valid questionnaires were retrieved(valid recovery rate=90.3%). The subjects were from 49 national medical centers with the average age of 31.65±6.65. The average years of working experience were 6.41±5.438. With each and every piece of the recommendation, approximately 50% of the subjects completely agreed(VAS 10), about 40% partially agreed(VAS 5–9), under 10%(VAS 1–4) partially disagreed and around 1%(VAS 0) totally disagreed(shown in figure 1A). As for the feasibility, around 30% of the subjects thought the recommendations were fully feasible(VAS 10), about 50% considered partially feasible (VAS 5–9), 10% partially infeasible(VAS 1–4), and less than 1% totally infeasible(shown in figure 1B). Factors made the subjects disapprove of the recommendations include busy clinical loading(39.98%), lack of professional knowledge and nursing skills(25.7%), patients did not accept the extended role of nurses(17.35%). In the meantime, lack of working time(16.33%), shortage of professional nurses(12.74%), lack of training and education(10.59%), lack of professional knowledge(9.22%), attitude of patients toward nurses(8.28%), and lack of financial support(7.53%) were the reasons that made subjects think the recommendations infeasible in China. Figure 1 the agreement and feasibility analysis of the EULAR recommendations in China Conclusions: The role and tasks of nurses should be clearly described in the framework in China. Professional training and educational nursing programs at both basic and advanced levels need to be well developed with the aim of providing better care and bringing added value to patients at a lower cost.

Gallbladder cancer is an invasive cancer with a discouraging prognosis, and early detection and active intervention are of great value. To establish a more accurate and effective survival model to predict the prognosis of patients with non-metastatic gallbladder after surgical resection. A retrospective analysis was conducted in non-metastatic gallbladder cancer patients who were registered in the surveillance, epidemiology and end results database from 2010 to 2014. Univariate analysis and multivariate analysis were performed for the related factors that might affect the gallbladder cancer-specific survival. A prognostic gallbladder cancer-specific survival model was established using the nomogram tool. The discrimination test was measured by the c-index, and the conformance test was performed by a calibration curve. In all, 1422 patients with non-metastatic gallbladder cancer were identified. The prognostic factors include age, gender, lymph node dissection, postoperative chemotherapy, tumor size, histological grading, pT stage and pN stage. The gallbladder cancer-specific survival model was established based on the prognostic factors. The model’s c-index was 0.775, and the 7th AJCC staging c-index was 0.649. The calibration curves showed a good correlation between prediction and actual survival. This study established the gallbladder cancer-specific survival model successfully. Compared with the 7th AJCC stage, this model refined the contribution of the pT stage, pN stage and other related factors and was demonstrated to be more accurate and reliable. More importantly, this model may allow clinicians to screen patients with a poor prognosis for closer follow-up or adjuvant treatment.

The present study aimed to examine the functional and molecular effects of miR‑128 in epilepsy, in order to investigate its potential protective mechanisms. Firstly, miR‑128 expression in rats with lithium chloride‑induced epilepsy was demonstrated to be increased compared with the control rats. Subsequently, results from an in vitro epilepsy model demonstrated that overexpression of miR‑128 promoted nerve cell apoptosis, increased the protein expression of tumor protein p53, BCL2 associated X (Bax) and Cytochrome c, and enhanced caspase‑3/9 activity, whereas it suppressed the protein expression of sirtuin 1 (SIRT1). In addition, these alterations may be reversed by the downregulation of miR‑128. Furthermore, treatment with CAY10602, a SIRT1 agonist, reduced the effects of miR‑128 on nerve cells in vitro. Treatment with pifithrin‑β hydrobromide, a p53 inhibitor, was additionally able to mitigate the effects of miR‑128 in vitro. In conclusion, the present findings indicated that anti‑miR‑128 may exert neuroprotective effects in epilepsy, through the SIRT1/p53/Bax/Cytochrome c/caspase signaling pathway.

BACKGROUND Laparoscopic common bile duct exploration (LCBDE) has been verified to be a comparatively effective treatment approach for uncomplicated choledocholithiasis, and it has been previously proposed that the primary duct closure (PDC) technique, in which the bile duct can directly be sutured in only 1 step compared with the T-tube drainage (TTD), can be deemed a choice after LCBDE; however, the conventional TTD performance is controversial in the minimally invasive surgery era. On the basis of the above-mentioned point, this meta-analysis was conducted to assess the different effects between TTD and PDC after LCBDE. MATERIALS AND METHODS In PubMed, EMBASE, and the Cochrane Library, literature search was conducted to screen out randomized controlled trials (RCTs) to compare PDC with TTD. The analyzed outcome variables included overall morbidity, biliary-specific morbidity (retained stones, biliary leak, biliary peritonitis), other morbidities, operating time, postoperative hospital stay, reintervention (surgery, endoscopy/radiology), and median hospital expenses. RESULTS In this meta-analysis, there are 4 RCTs qualifying for inclusion, including 396 patients in all (222 in PDC and 214 in TTD). With respect to postoperative overall morbidity (P

Background Enterovirus 71 (EV-A71) shows a potential of rapid death, but the natural history of the infection is poorly known. This study aimed to examine the natural history of EV-A71 infection. Methods This was a prospective longitudinal observational study performed between January 1st and October 31st, 2012, at three hospitals in Guangdong, China. Subjects with positive EV-A71 RNA laboratory test results were included. Disease progression was documented with MRI, autopsies, and follow-up. Symptoms/signs with potential association with risk of death were analyzed. Results Among the 288 patients, neurologic symptoms and signs were observed (emotional movement disorders, dyskinesia, involuntary movements, autonomic dysfunction, and disturbance of consciousness). Some of them occurred as initial symptoms. Myoclonic jerks/tremors were observed among >50% of the patients; nearly 40% of patients presented fatigue and 25% were with vomiting. Twenty-eight patients (9.7%) presented poor peripheral perfusion within 53.4 ± 26.1 h; 23 patients (8.0%) presented pulmonary edema and/or hemorrhage within 62.9 ± 28.6 h. Seventeen (5.9%) patients were in a coma. Seven (2.4%) patients died within 62.9 ± 28.6 h. Seventy-seven survivors underwent head and spinal cord MRI and 37.7% (29/77) showed abnormalities. Two fatal cases showed neuronal necrosis, softening, perivascular cuffing, colloid, and neuronophagia phenomenon in the brainstem. Conclusions Patients with EV-A71 infection showed high complexity of symptoms and onset timing. Death risk may be indicated by autokinetic eyeball, eyeball ataxia, severe coma, respiratory rhythm abnormality, absent pharyngeal reflex, ultrahyperpyrexia, excessive tachycardia, pulmonary edema and/or hemorrhage, and refractory shock and ataxic respiration. Early assessment of these symptoms/signs is important for proper management.

Polycomb group (PcG) proteins Ring1B and EZH2, which have been characterized as catalyzing the two epigenetic modifications H2AK119 monoubiquitination (H2AK119Ub1) and H3K27 trimethylation (H3K27Me3), are well-known epigenetic silencers implicated in embryonic development and tumorigenesis. However, the status of polycomb-associated histone modifications and their clinical implications in pancreatic cancer remain unclear. Here, we performed immunohistochemistry on tissue microarrays (TMAs) containing 80 pairs of human pancreatic cancer specimens to assess the expression levels of Ring1B, H2AK119Ub1, EZH2, and H3K27Me3 in tumors. More than 50% of the tumor cells showed a high expression of H2AK119Ub1, Ring1B, and EZH2, whereas more than 50% of the tumor cells showed a low level of H3K27Me3. Different expression patterns of H2AK119Ub1 and H3K27Me3 in tumors were negatively correlated (r = -0.247, P = 0.027). Both H2AK119Ub1 and H3K27Me3 independently predicted the clinical prognosis. In particular, a combinatorial pattern of elevated H2AK119Ub1 and decreased H3K27Me3 in tumors was significantly correlated with a poorer prognosis. Furthermore, compared to the tumor, lymph node, metastasis (TNM) staging system, histone modifications can discriminate the survival difference more accurately, especially for patients with stage I or stage II tumors. Simultaneous silencing of Ring1B and EZH2 via shRNA depleted H2AK119Ub1 and H3K27Me3 in the pancreatic cancer cells PanC1 and AsPC1, enhanced HOX gene derepression, and inhibited tumor cell growth in vitro and in tumor xenograft models. These results demonstrated that H2AK119Ub1 and H3K27Me3 cooperate in tumors and are associated with the clinical prognosis in combinatorial patterns. We have proposed that epigenetic modifications may serve as discriminatory biomarkers for molecular staging of pancreatic cancer.

This study aims to investigate the roles of lncRNA ANRIL in epithelial-mesenchymal transition (EMT) by regulating the ATM-E2F1 signaling pathway in pancreatic cancer (PC). PC rat models were established and ANRIL overexpression and interference plasmids were transfected. The expression of ANRIL, EMT markers (E-cadherin, N-cadherin and Vimentin) and ATM-E2F1 signaling pathway-related proteins (ATM, E2F1, INK4A, INK4B and ARF) were detected. Small molecule drugs were applied to activate and inhibit the ATM-E2F1 signaling pathway. Transwell assay and the scratch test were adopted to detect cell invasion and migration abilities. ANRIL expression in the PC cells was higher than in normal pancreatic duct epithelial cells. In the PC rat models and PC cells, ANRIL interference promoted the expressions of INK4B, INK4A, ARF and E-cadherin, while reduced N-cadherin and Vimentin expression. Over-expressed ANRIL decreased the expression of INK4B, INK4A, ARF and E-cadherin, but raised N-cadherin and Vimentin expressions. By inhibiting the ATM-E2F1 signaling pathway in PC cells, E-cadherin expression increased but N-cadherin and Vimentin expressions decreased. After ANRIL was silenced or the ATM-E2F1 signaling pathway inhibited, PC cell migration and invasion abilities were decreased. In conclusion, over-expression of lncRNA ANRIL can promote EMT of PC cells by activating the ATM-E2F1 signaling pathway.

NAD(P)H:quinone oxidoreductase 1 (NQO1) is a phase II enzyme that participates in the detoxification of dopamine-derived quinone molecules and reactive oxygen species. Our prior work using a proteomic approach found that NQO1 protein levels were significantly decreased in stable hepatitis B virus (HBV)-producing hepatoma cells relative to the empty-vector-transfected controls. However, the mechanism and biological significance of the NQO1 suppression remain elusive. In this study we demonstrate that HBV X protein (HBx) induces epigenetic silencing of NQO1 in hepatoma cells through promoter hypermethylation via recruitment of DNA methyltransferase DNMT3A to the promoter region of the NQO1 gene. In HBV-related hepatocellular carcinoma (HCC) specimens, HBx expression was correlated negatively to NQO1 transcripts but positively to NQO1 promoter hypermethylation. Downregulation of NQO1 by HBx reduced intracellular glutathione levels, impaired mitochondrial function, and increased susceptibility of hepatoma cells to oxidative stress-induced cell injury. These results suggest a novel mechanism for HBV-mediated pathogenesis of chronic liver diseases, including HCC.

Geometric errors are seldom considered the generations of CMM dynamic errors. This paper presents the dynamic effects of the geometric errors of CMM in fast probing, and investigates the properties with Finite Elements Method (FEM). The FEM model was composed of CMM moving bridge and its guide way. Presuming CMM guide way as an ideal rigid geometry, then angular errors were generated by the rotations of guide way around a corresponding coordinate axis, while translation errors came from the translations of guide way. Thus the 6 geometric errors on each guide way were completely decoupling and the corresponding dynamic effects were studied respectively. Analyses show that the angular errors around Y and Z-axes, Y(x) and Z(x), can induce remarkable dynamic effects at probe tip, especially in a CMM with low stiffness air bearing.

To evaluate time trends of exomphalos prevalence using a large population-based study with cases identified by the Liaoning Birth Defects Registry including 14 cities over the course of a 10-year period. Exomphalos prevalence, percent change, annual percent change (APC), and contribution rates of each city were calculated. Additionally, epidemiological characteristics of this malformation were described. We observed 516 cases of exomphalos among 3,248,954 live births. Birth prevalence of exomphalos was 1.59 per 10,000 live births with non-significant change during the observational period (APC = −1.19%, P = 0.48). However, significantly decreasing trends were noticed in three cities: Fushun (APC = −9.15%, P = 0.03), Benxi (APC = −11.49%, P = 0.05), and Yingkou (APC = −16.47%, P = 0.04), contributing 62.77% of the decreasing trend of overall prevalence. The mean maternal age, gestational age, and birth weight was 28.4 years (standard deviation [SD], 6.1 years), 25.6 weeks (SD, 8.6 weeks), and 1236.2 gram (SD, 1164.4 gram). For time of diagnosis, 79.8% (n = 412) cases were diagnosed during pregnancy. In summary, the prevalence of exomphalos in Liaoning province did not change remarkably during 2006 to 2015. Future studies are warranted to investigate the risk factors and create prevention strategies for this disease.

Antibiotics as emerging environmental contaminants, are widely used in both human and veterinary medicines. A solid-state nanopore sensing method is reported in this article to detect Tetracycline, which is based on Tet-off and Tet-on systems. rtTA (reverse tetracycline-controlled trans-activator) and TRE (Tetracycline Responsive Element) could bind each other under the action of Tetracycline to form one complex. When the complex passes through nanopores with 8 ~ 9 nanometers in diameter, we could detect the concentrations of Tet from 2 ng/mL to 2000 ng/mL. According to the Logistic model, we could define three growth zones of Tetracycline for rtTA and TRE. The slow growth zone is 0–39.5 ng/mL. The rapid growth zone is 39.5−529.7 ng/mL. The saturated zone is > 529.7 ng/mL. Compared to the previous methods, the nanopore sensor could detect and quantify these different kinds of molecule at the single-molecule level.

To identify trends in the prevalence of gastroschisis on the basis of a large population-based observation study with cases identified by the Liaoning Birth Defects Registry including 14 cities over the course of a 10-year period. Data were obtained from the aforementioned registry which was maintained by the Liaoning Women and Children’s Health Hospital, a comprehensive care institution as well as being responsible for the women’s and children’s health care guidance in this province. Gastroschisis prevalence, percent change, annual percent change (APC), and contribution rates of each city were calculated. We observed 747 cases of gastroschisis among 3,248,954 live births, for a prevalence of 2.30 per 10,000 births. The gastroschisis prevalence significantly decreased by 12.63% per year in Liaoning Province. Although the decreasing trends were observed in all these 14 cities, significant results were only observed in Shenyang (APC = −16.31%), Tieling (APC = −20.23%), and Chaoyang (APC = −13.50%). Notably, Tieling, Shenyang, and Yingkou were the three major cities which contributed almost 37.17% of the decreasing trend of gastroschisis in Liaoning Province. In conclusion, our findings demonstrate that the prevalence of gastroschisis has been decreasing during the recent decade among 14 cities in Liaoning Province.

Objective : A major challenge in radiographic identification is the inconsistent orientation between clinical (ante-mortem, AM) and post-mortem (PM) radiographs. The objectivity and accuracy of radiological identification would be greatly enhanced by post-processing techniques that allow quantitative comparison of PM CT data in the same orientation as the AM CT data. Methods : We applied a post-processing technique to reposition a multislice computed tomography (MSCT) scan for spatial registration with a CT radiograph from the same patient. A second set of MSCT images from different individuals served as the non-matched control group. The consistency in radiographic positioning eliminated subjectivity in the comparison and identification process because the radiograph superposition provided objective evidence that confirmed the identification with fine detail. Results : A quantitative comparison with statistical validation was achieved by measuring a set of 14 landmarks from the images. Discrimination of identity based on logistic regression analysis of the earlier CT patient scans (the AM group) versus subsequent MSCT scans (the PM group) was objective and reliable. Conclusion : This quantitative comparison depends less on subjective judgment and the experience of the examiner, and so may meet legal standards.

This study focuses on providing diagnosis and treatment for xanthogranulomatous cholecystitis (XGC). Clinical data from 39 patients diagnosed with XGC by pathological examination between 2002 and 2010 were analyzed retrospectively. As a result, in this group of patients, the male to female ratio was 30:9 and the average age of XGC onset was 62.2 years. Clinical manifestation of the disease was similar to general cholecystitis and preoperative CT examination showed that there were only 4 XGC cases, while the others were possibly misdiagnosed. Intraoperative observations showed that all the patients had gallbladder wall thickening. This was associated with gallbladder stones in 37 patients (94.9 %), choledocholith in 11 patients (28.2 %), and Mirizzi syndrome in 5 patients (12.8 %). In this study, intraoperative frozen section pathology was conducted in 14 patients and no gallbladder cancer was found. Laparoscopic cholecystectomy was performed on 7 patients, of which two were transferred to laparotomy. Of the remaining 32 cases, 25 were subjected to open cholecystectomy, 3 to partial cholecystectomy, and 4 to the cholecystectomy and partial liver wedge resection. It was concluded that XGC is a unique type of cholecystitis with atypical clinical manifestations and is often difficult to diagnose preoperatively. Pathological examination is a key to diagnose XGC and cholecystectomy is the primary surgical treatment. In patients with choledochectasia or jaundice, for whom we cannot exclude calculus of common bile duct, common bile duct exploration should be considered. The prognosis of XGC appears to be good with the above approaches.
