Abstract Background: immunonutrition has been introduced and proposed to have positive modulating effects on inflammatory and immune responses in surgical patients. This meta-analysis aimed to assess whether perioperative enteral immunonutrition (EIN) can reduce postoperative complications or reduce inflammatory responses in esophageal cancer (EC) patients undergoing esophagectomy. Methods: PubMed, Embase, Web of science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of EIN before and/or after surgery in EC patients undergoing esophagectomy were identified. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. Results: ten RCTs involving 1,052 patients were included in the meta-analysis, including 573 patients in the EIN group and 479 patients in the enteral nutrition (EN) group. Overall, no significant difference was observed between the two groups in the incidence of postoperative pneumonia, surgical site infection, intra-abdominal abscess, septicemia, and urinary tract infection. No significant incidence of postoperative anastomotic leakage, acute respiratory distress syndrome (ARDS), and in-hospital mortality was found. Conclusions: perioperative enteral immunonutrition did not reduce the incidence of infectious complications and anastomotic leakage in EC patients undergoing esophagectomy, nor did it reduce postoperative CRP and IL-6, but did not increase in-hospital mortality.

Resumen Antecedentes: se ha introducido y propuesto la inmunonutrición para regular activamente la inflamación y la respuesta inmune en pacientes quirúrgicos. El presente metaanálisis fue diseñado para evaluar si la inmunonutrición enteral perioperatoria (EIN, por sus siglas en inglés) puede reducir las complicaciones postoperatorias o la inflamación en pacientes con cáncer de esófago (CE) sometidos a esofagectomía. Métodos: se realizó una búsqueda sistemática en las bases de datos de PubMed, Embase, Web of Science, EBSCO y Cochrane Library. Se evaluó el efecto de la EIN preoperatoria y/o postoperatoria en un ensayo aleatorizado controlado (RCT) en pacientes con cáncer de esófago sometidos a esofagectomía. Dos investigadores buscaron independientemente artículos, extrajeron datos y evaluaron la calidad de los artículos incluidos. Resultados: el metanálisis incluyó diez ensayos controlados aleatorios en los que participaron 1.052 pacientes, de los cuales 573 fueron incluidos en el grupo EIN y 479, en el grupo de nutrición enteral (NE). En general, no hubo diferencia significativa en la incidencia de neumonía postoperatoria, infección del sitio quirúrgico, absceso intraperitoneal, sepsis e infección del tracto urinario entre los dos grupos. No hubo diferencia significativa en la incidencia de fístula anastomótica postoperatoria, síndrome de distrés respiratorio agudo (SDRA) y mortalidad hospitalaria. Conclusión: la inmunonutrición enteral perioperatoria no puede reducir la incidencia de complicaciones infecciosas postoperatorias y fístulas anastomóticas, ni la PCR postoperatoria ni la IL-6. Pero no aumentó la mortalidad hospitalaria.

Abstract Backgroud Homocitrulline (Hcit), is involved in the pathological processes of some diseases. However, the role and function of Hcit (CBL) in human skin remains largely obscure. Objective To investigate the correlation of the level of Hcit in seborrheic keratosis, skin aging, and its clinical significance. Methods Immunohistochemistry was used to analyze the level of Hcit in skin lesions of seborrheic keratosis (SK), unaffected skin (distant 0.5 centimeters from SK lesion), and normal skin of healthy subjects in the control group. ELISA test was used to detect the serum level of CBL in SK patients and healthy subjects of different ages. Results Hcit was mainly localized in the nucleus of epidermal cells. In healthy control skin, the expression of Hcit increased with age and showed a positive correlation with age (the correlation coefficient was 0.806, p = 0.0002). The expressional level of Hcit in SK lesions was higher than that in healthy control skin (Z = −3.703, p = 0.0002). The serum level of CBL in healthy subjects and in SK patients increased with age (the correlation coefficient were 0.5763, p = 0.0032; 0.682, p = 0.004. respectively). The serum level of CBL in SK patients was higher than that in healthy subjects (Z = −2.19, p = 0.030). Study limitations The small serum sample size in the study. Conclusion The high expressional level of Hcit is correlated with seborrheic keratosis and skin aging. HCit may be one of the potential biomarkers of skin aging.

Abstract Objectives: The incidence of cerebellar Glioblastoma Multiforme (cGBM) is rare. Database like TCGA have not distinguish cGBM from GBM, our knowledge on cGBM gene expression characteristics is limited. The expression status of Oligodendrocyte Lineage Transcription factor 2 (OLIG2) and its clinical significance in cGBM is still unclear. Methods: The clinical data and tissue specimens of 73 cGBM patients were retrospectively studied. The association between OLIG2 expression level and the demographic characteristics of cGBM patients was identified by the Chi-Square test. The survival curves were drawn by Kaplan-Meier analysis. The independent prognostic factors was calculated according to Cox regression analysis. Results: The OLIG2 high expression was observed in about 57.5% (42/73) of the cGBM patients. Patients with high OLIG2 expression levels had a higher alive ratio at the end of follow-up (alive ratio: 70.6% vs. 29.4%, p = 0.04). The median survival time was 21 months and 13 months for high and low expression of OLIG2 (p < 0 .05). Univariate analysis and Multivariate analysis indicated that EOR (HR = 3.89, 95% CI 1.23−12.26, p = 0.02), low OLIG2 expression (HR = 5.26, 95% CI 1.13−24.59, p = 0.04), and without adjuvant therapy (HR = 4.95, 95% CI 1.22−20.00, p = 0.03) were independent risk factors for the OS of cGBM patients. Conclusion: High expression level of OLIG2 could be used as an independent favorable prognosis indicator in cGBM patients and be recognized as a characteristic biomarker of cGBM.

Abstract Flaxseed (Linum usitatissimum L.), one kind of common oilseeds, has many biologically active compounds including α-linolenic acid (ALA), lignan and dietary fiber. At present, the research of flaxseed is focused on biological and clinical studies of its compounds. However, the studies of flaxseed protein obtained generally from flaxseed cake, are relatively limited. As many other kinds of plant proteins, flaxseed protein presents many excellent functionalities which can be used for food applications. Many evidence have showed that flaxseed protein hydrolysates can provide health benefits to our body, such as anti-bacterial activity, antioxidant capacity and angiotensin-converting enzyme inhibition ability. Therefore, in order to make better use of flaxseed protein in foods, the extraction, functionalities and applications of flaxseed protein were reviewed in this paper. In addition, the preparation of flaxseed protein hydrolysates was discussed.

Abstract The miRNA-1180 anti-cancer effects in hepatocellular carcinoma cell were studied. 33 hepatocellular carcinoma patients were collected. In cancer and adjacent normal tissue from patients, TRAF1 protein and miR-1180 expression was determined by HE staining, IHC and RT-PCR methods. In the cell experiments, HepG2 cells were divided into three groups: NC group, BL group and miRNA group. The cells of NC group were un-treated; BL group were transfected with empty camer; miRNA group were transfixed with miRNA-1180. We determinates cell proliferation rate of difference groups, measuring the cell apoptosis rate and cell cycle of difference groups by flow cytometry, detected cell invasion and migration abilities of difference groups by transwell and wound healing assay and evaluating relative proteins expressions by WB assay. Compared with Normal liver tissue, cell infiltrations were significantly increased. miR-1180 was negative correlation with TRAF. The cell proliferation rate of miRNA group was significantly lower than that of NC group; The cell apoptosis and G1 phase rates were significantly difference among three groups; however, P53 and P21 protein expressions were significantly increased in miRNA groups. Over-expression miRNA-1180 had effect to inhibit HepG2 cell proliferation, invasion, migration and improve HepG2 cell apoptosis by regulation TRAF1/NF-κB signaling pathway.

Data about the feasibility and safety of thoracoscopic surgery under non-intubated anesthesia and regional block are limited. In this prospective study, 57 consecutive patients scheduled for thoracoscopic surgery were enrolled. Patients were sedated with dexmedetomidine and anesthetized with propofol and remifentanil. Ropivacaine was used for intercostal nerve and paravertebral block. Lidocaine was used for vagal block. The primary outcomes were mean arterial pressure (MAP), heart rate (HR), oxygen saturation, and end-tidal carbon dioxide partial pressure (ETCO2) at T0 (pre-anesthesia), T1 (immediately after laryngeal mask/nasopharyngeal airway placement), T2 (immediately after skin incision), T3 (10 min after opening the chest), T4 (end of surgery), and T5 (immediately after laryngeal mask/nasopharyngeal airway removal). One patient required conversion to intubation, 15 developed intraoperative hypotension, and two had hypoxemia. MAP at T0 and T5 was higher than at T1–T4; MAP at T3 was lower (P<0.05 vs other time points). HR at T0 and T5 was higher (P<0.05 vs other time points). ETCO2 at T2 and T3 was higher (P<0.05 vs other time points). Arterial pH, PCO2, and lactic acid at T1 differed from values at T0 and T2 (P<0.05). The Quality of Recovery-15 (QoR-15) score at 24 h was lower (P<0.05). One patient experienced dysphoria during recovery. Thoracoscopic surgery with regional block under direct thoracoscopic vision is a feasible and safe alternative to conventional surgery under general anesthesia, intubation, and one-lung ventilation.

Abstract Background: Abscisic acid-, stress-, and ripening-induced (ASR) genes are a class of plant specific transcription factors (TFs), which play important roles in plant development, growth and abiotic stress responses. The wheat ASRs have not been described in genome-wide yet. Methods: We predicted the transmembrane regions and subcellular localization using the TMHMM server, and Plant-mPLoc server and CELLO v2.5, respectively. Then the phylogeny tree was built by MEGA7. The exon–intron structures, conserved motifs and TFs binding sites were analyzed by GSDS, MEME program and PlantRegMap, respectively. Results: In wheat, 33ASR genes were identified through a genome-wide survey and classified into six groups. Phylogenetic analyses revealed that the TaASR proteins in the same group tightly clustered together, compared with those from other species. Duplication analysis indicated that the TaASR gene family has expanded mainly through tandem and segmental duplication events. Similar gene structures and conserved protein motifs of TaASRs in wheat were identified in the same groups. ASR genes contained various TF binding cites associated with the stress responses in the promoter region. Gene expression was generally associated with the expected group-specific expression pattern in five tissues, including grain, leaf, root, spike and stem, indicating the broad conservation of ASR genes function during wheat evolution. The qRT-PCR analysis revealed that several ASRs were up-regulated in response to NaCl and PEG stress. Conclusion: We identified ASR genes in wheat and found that gene duplication events are the main driving force for ASR gene evolution in wheat. The expression of wheat ASR genes was modulated in responses to multiple abiotic stresses, including drought/osmotic and salt stress. The results provided important information for further identifications of the functions of wheat ASR genes and candidate genes for high abiotic stress tolerant wheat breeding.

Abstract Rapeseed is one of important oil crops in China. Better understanding of the regulation network of main agronomic traits of rapeseed could improve the yielding of rapeseed. In this study, we obtained an influrescence mutant that showed a fusion phenotype, similar with the Arabidopsis clavata-like phenotype, so we named the mutant as Bnclavata-like (Bnclv-like). Phenotype analysis illustrated that abnormal development of the inflorescence meristem (IM) led to the fused-inflorescence phenotype. At the stage of protein abundance, major regulators in metabolic processes, ROS metabolism, and cytoskeleton formation were seen to be altered in this mutant. These results not only revealed the relationship between biological processes and inflorescence meristem development, but also suggest bioengineering strategies for the improved breeding and production of Brassica napus.

Abstract Background: Non-canonical Wnt pathways play important roles in liver fibrosis. Notum is a newly discovered inhibitor to Wnt proteins. This study was to investigate anti-fibrotic effects of Notum. Methods: 53 patients with hepatitis B virus (HBV) infection as well as a cell co-culture system of LX-2 and Hep AD38 cells were engaged in this study. Clinical, biological and virological data of each patient were analyzed. Cell viability was detected at different time points. mRNA and protein levels of NFATc1 (Nuclear factor of activated T-cells), Jnk, α-SMA, Col1A1 and TIMP-1 were detected both in LX-2 and liver tissue. Protein levels of NFATc1 and Jnk in liver tissue and their correlations with fibrosis score were analyzed. Results: Hepatitis B virus replication up-regulated Wnt5a induced NFATc1 and Jnk activity in Hep AD38. Notum suppressed NFATc1, Jnk and fibrosis genes expression, reduced cell viability in co-cultured LX-2 cells induced by HBV. Interestingly, Patients with HBV DNA > 5log copies/ml had higher mRNA levels of NFATc1 and fibrosis genes than patients with HBV DNA < 5log copies/ml. Most importantly, protein expressions of NFATc1 and pJnk have positive correlations with liver fibrosis scores in HBV-infected patients. Conclusions: Our data showed that Notum inhibited HBV-induced liver fibrosis through down-regulating Wnt 5a mediated non-canonical pathways. This study shed light on anti-fibrotic treatment.

Primary biliary cirrhosis (PBC) is a chronic and slowly progressive cholestatic liver disease of autoimmune etiology. A number of questions regarding its etiology are unclear. CD4+CD25+ regulatory T cells (Tregs) play a critical role in self-tolerance and, for unknown reasons, their relative number is reduced in PBC patients. B-cell-activating factor (BAFF) is a key survival factor during B-cell maturation and its concentration is increased in peripheral blood of PBC patients. It has been reported that activated B cells inhibit Treg cell proliferation and there are no BAFF receptors on Tregs. Therefore, we speculated that excessive BAFF may result in Treg reduction via B cells. To prove our hypothesis, we isolated Tregs and B cells from PBC and healthy donors. BAFF and IgM concentrations were then analyzed by ELISA and CD40, CD80, CD86, IL-10, and TGF-β expression in B cells and Tregs were measured by flow cytometry. BAFF up-regulated CD40, CD80, CD86, and IgM expression in B cells. However, BAFF had no direct effect on Treg cell apoptosis and cytokine secretion. Nonetheless, we observed that BAFF-activated B cells could induce Treg cell apoptosis and reduce IL-10 and TGF-β expression. We also showed that BAFF-activated CD4+ T cells had no effect on Treg apoptosis. Furthermore, we verified that bezafibrate, a hypolipidemic drug, can inhibit BAFF-induced Treg cell apoptosis. In conclusion, BAFF promotes Treg cell apoptosis and inhibits cytokine production by activating B cells in PBC patients. The results of this study suggest that inhibition of BAFF activation is a strategy for PBC treatment.

The biological functions of the BC047440 gene highly expressed by hepatocellular carcinoma (HCC) are unknown. The objective of this study was to reconstruct antisense eukaryotic expression vectors of the gene for inhibiting HepG2 cell proliferation and suppressing their xenograft tumorigenicity. The full-length BC047440 cDNA was cloned from human primary HCC by RT-PCR. BC047440 gene fragments were ligated with pMD18-T simple vectors and subsequent pcDNA3.1(+) plasmids to construct the recombinant antisense eukaryotic vector pcDNA3.1(+)BC047440AS. The endogenous BC047440 mRNA abundance in target gene-transfected, vector-transfected and naive HepG2 cells was semiquantitatively analyzed by RT-PCR and cell proliferation was measured by the MTT assay. Cell cycle distribution and apoptosis were profiled by flow cytometry. The in vivo xenograft experiment was performed on nude mice to examine the effects of antisense vector on tumorigenicity. BC047440 cDNA fragments were reversely inserted into pcDNA3.1(+) plasmids. The antisense vector significantly reduced the endogenous BC047440 mRNA abundance by 41% in HepG2 cells and inhibited their proliferation in vitro (P < 0.01). More cells were arrested by the antisense vector at the G1 phase in an apoptosis-independent manner (P = 0.014). Additionally, transfection with pcDNA3.1(+)BC047440AS significantly reduced the xenograft tumorigenicity in nude mice. As a novel cell cycle regulator associated with HCC, the BC047440 gene was involved in cell proliferation in vitro and xenograft tumorigenicity in vivo through apoptosis-independent mechanisms.

Most frequently reported Chinese renal biopsy data have originated from southeastern China. The present study analyzed the renal biopsy data from northeastern China. The records of 1550 consecutive native patients who were diagnosed with primary glomerular diseases (PGD) after renal biopsy at our hospital during 2005-2009 were used. These patients were divided into four age groups for stratified analysis: <15, 15-44, 45-59, and ≥60 years old. Among PGD, minimal change disease (MCD) was the most common histologically diagnosed disease (30.7%), followed by IgA nephropathy (IgAN), mesangial proliferative glomerulonephritis (MsPGN), membranous nephropathy (MN), membranoproliferative glomerulonephritis (MPGN), focal segmental glomerulosclerosis (FSGS), and endocapillary proliferative glomerulonephritis (EnPGN). MCD was the disease most frequently observed (43.7%) in the <15-year-old group. MsPGN was the most common disease in the elderly group (38.1%). MsPGN was more prevalent in females (27.8%), whereas MCD was more prevalent in males (35.3%). Primary glomerular diseases constituted the most commonly encountered group of diseases with a high prevalence of MCD, which predominantly affected males and young adults. The prevalence of MCD was high in northeastern China. Further study is necessary to expand the epidemiologic data available for renal disease in China.

Taurine has positive effects on bone metabolism. However, the effects of taurine on osteoblast apoptosis in vitro have not been reported. The aim of this study was to investigate the activity of taurine on apoptosis of mouse osteoblastic MC3T3-E1 cells. The data showed that 1, 5, 10, or 20 mM taurine resulted in 16.7, 34.2, 66.9, or 63.75% reduction of MC3T3-E1 cell apoptosis induced by the serum deprivation (serum-free α-MEM), respectively. Taurine (1, 5, or 10 mM) also reduced cytochrome c release and inhibited activation of caspase-3 and -9, which were measured using fluorogenic substrates for caspase-3/caspase-9, in serum-deprived MC3T3-E1 cells. Furthermore, taurine (10 mM) induced extracellular signal-regulated kinase (ERK) phosphorylation in MC3T3-E1 cells. Knockdown of the taurine transporter (TAUT) or treatment with the ERK-specific inhibitor PD98059 (10 μM) blocked the activation of ERK induced by taurine (10 mM) and abolished the anti-apoptotic effect of taurine (10 mM) in MC3T3-E1 cells. The present results demonstrate for the first time that taurine inhibits serum deprivation-induced osteoblast apoptosis via the TAUT/ERK signaling pathway.
