RATIONALE: Hepatic alveolar echinococcosis (HAE) is a potentially fatal and chronically progressive infestation that is caused by the multivesicular metacestode of Echinococcus multilocularis (EM). HAE behaves like a malignant tumor and has been referred to as "worm cancer." The main treatment method for HAE is surgical resection. PATIENT CONCERNS: We present a 41-year-old Tibetan alveolar echinococcosis (AE) patient with AE lesions invading the right liver lobe and retrohepatic inferior vena cava (RHIVC)...

To assess the safety and efficacy of enhanced recovery after surgery (ERAS) as compared with the traditional care in patients undergoing liver surgery and optimization of enhanced recovery programs.Literature, until August 2016, was searched to identify the comparative studies evaluating preoperative hospital stay time, complications, and C-reactive protein (CRP). Pooled odds ratios (OR) or weighted mean differences (WMDs) were calculated with either the fixed or random effect model.These studies included a total of 524 patients: 254 treated with ERAS and 270 with traditional care...

We use the Hill function to analyze the dynamics of Tc-99m 2 methoxy-isobutyl-isonitrile (Tc-MIBI) scintigraphy data and to examine the earlier lower extremity microvascular perfusion of diabetic patients without typical clinical symptoms and with the preserved normal ankle-brachial index (ABI).Eighty-eight participants (30 healthy control, 34 diabetic patients, and 24 diabetic patients with peripheral arterial disease [PAD]) were recruited and applied Tc-MIBI scintigraphy. Fourteen diabetic patients with PAD also underwent computed tomography angiography (CTA) examination and were performed endovascular interventions...

Follicular regulatory T (Tfr) cells differentiate from conventional regulatory T (Treg) cells and suppress excessive germinal center (GC) responses by acting on both GC B cells and T follicular helper (Tfh) cells. Here, we examined the impact of mTOR, a serine/threonine protein kinase that senses and integrates diverse environmental cues, on the differentiation and functional competency of Tfr cells in response to protein immunization or viral infection. By genetically deleting Rptor or Rictor, essential components for mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2), respectively, we found that mTORC1 but not mTORC2 is essential for Tfr differentiation...

Peroxisome proliferators activated receptors (PPARs) are closely related to human chronic disease, such as diabetes mellitus and the other metabolic diseases. In this study, a cell-based PPARs (PPAR α/β/γ) model was developed for the screening of PPARs agonists from Alismatis Rhizoma (AR). Firstly, 293T cells were transfected with the reconstructed plasmid pBind-PPAR (α, β, or γ)-LBD and reporter gene pGL4.35, and the known PPARs agonists were used as the positive control (fenofibrate for PPARα, L165041 for PPARβ, and rosiglitazone for PPARγ)...

At present, little is known about the influence of mesenchymal stem cell (MSC) transplantation on connexin43 (Cx43) and connexin45 (Cx45) remodeling in the ischemic heart. In this study, we investigated the effect of MSC transplantation on Cx43 and Cx45 remodeling in the ischemic heart. Wistar rats were subjected to left anterior descending artery ligation to induce myocardial infarction (MI) and then randomly allocated to receive an intramyocardial injection of PBS (MI group) or 5-azacytidine-induced MSCs (MSCs group)...

IDH1 R132H mutation is an important marker of survival in patients with gliomas. Although there are many changes of genes in tumour malignant progression, IDH1 R132H mutation status in glioma progression remained unclear. Here, an in-depth characterization of IDH1 R132H mutations were assessed by immunohistochemistry in 55 paired primary-recurrent astrocytomas tissues, including 5 paired primary pilocytic astrocytoma (pPA, WHO grade I), 35 paired primary low grade astrocytoma (pLGA, WHO grade II and III) and 15 paired primary high grade astrocytoma (pHGA/ Glioblastoma, WHO grade IV)...

This study examined the application of 64-slice spiral double-low computed tomography (CT) to evaluate the degree of coronary artery stenosis. We examined 45 patients with coronary heart disease by 64-slice spiral double-low CT and coronary angiography (CAG) to determine CT accuracy in evaluating coronary artery stenosis. Imaging analysis from 64-slice spiral double-low CT identified 199 segments with coronary stenosis from 45 patients, including 46 segments with mild stenosis, 38 with moderate stenosis and 115 with severe stenosis or artery occlusion...

Luteolin (3',4',5,7-tetrahydroxyflavone) is a common dietary flavonoid, which has been demonstrated to exert anticancer effects in multiple cancer models. However, the detailed mechanisms underlying the inhibitory effect of luteolin on glioblastoma cell metastasis remain poorly understood. The present study assessed the effects of luteolin in the U251MG and U87MG human glioblastoma cell lines. Luteolin treatment significantly inhibited glioblastoma cell migration, and this effect was associated with downregulated matrix metalloproteinase (MMP)-2, MMP-9 and upregulated tissue inhibitor of metalloproteinase (TIMP)-1 and TIMP-2...

Liver cancer primarily accounts for the majority of malignancies of the liver. MicroRNAs (miRNAs) are endogenous non-coding RNAs, which are important in tumorigenesis. Abnormal expression of microRNA-346 (miR-346) has been demonstrated in various types of human cancer, however, its expression and potential molecular mechanism in liver cancer remains to be elucidated. Expression levels of miR-346 in liver cancer cell lines were determined by quantitative polymerase chain reaction. The effect of miR-346 on proliferation was evaluated by an MTT assay; cell migration and invasion were evaluated by Transwell migration and invasion assays and target protein expression was determined by western blotting...

Premature leaf senescence occurs in the ultimate phase of the plant, and it occurs through a complex series of actions regulated by stress, hormones and genes. In this study, a proteomic analysis was performed to analyze the factors that could induce premature leaf senescence in two cotton cultivars. We successfully identified 443 differential abundant proteins (DAPs) from 7388 high-confidence proteins at four stages between non-premature senescence (NS) and premature senescence (PS), among which 158 proteins were over-accumulated, 238 proteins were down-accumulated at four stages, and 47 proteins displayed overlapped accumulation...

To study the effects of inducement on the expression of mouse embryonic stem cells SF1-G imprinted genes, Kcnq1 and Cdkn1c during the course of differentiation into islet-like cells in vitro. Mouse embryonic fibroblasts (MEFs) were isolated from pregnant mice embryos and fibroblast feeder cells were prepared by treating 3-5th generations MEFs with Mitomycin C. Moreover, mouse embryonic stem cells were induced to differentiate into islet-like cells directly. RT-PCR and Immunofluorescence staining were used to test the expression of islet cell-specific markers...

Arbuscular mycorrhizal (AM) fungi produce a recalcitrant glycoprotein, (glomalin-related soil protein (GRSP)), which can contribute to soil carbon sequestration. Here we made a first study to characterize the spatial distribution of GRSP fractions in a mangrove forest at Zhangjiang Estuary, Southeastern China and to explore potential contributions of GRSP to sediment organic carbon (SOC) in this forest. We identified GRSP fractions in surface sediments, as well as those at a depth of 50 cm. The contents of easily extractable GRSP (EE-GRSP), total GRSP (T-GRSP), GRSP in particulate organic matter (POM-GRSP) and GRSP in pore water (PW-GRSP) ranged between 1...

Plant SNF1-related protein kinase 2 (SnRK2) and protein phosphatase 2C (PP2C) family members are core components of the ABA signal transduction pathway. SnRK2 and PP2C proteins have been suggested to play crucial roles in fruit ripening and improving plant tolerance to drought stress, but supporting genetic information has been lacking in sweet cherry (Prunus avium L.). Here, we cloned six full-length SnRK2 genes and three full-length PP2C genes from sweet cherry cv. Hong Deng. Quantitative PCR analysis revealed that PacSnRK2...

BACKGROUND: Genistein is a natural isoflavone with many health benefits, including antitumour effects. Increased hypoxia-inducible factor 1 α (HIF-1α) levels and glycolysis in tumour cells are associated with an increased risk of mortality, cancer progression, and resistance to therapy. However, the effect of genistein on HIF-1α and glycolysis in hepatocellular carcinoma (HCC) is still unclear. METHODS: Cell viability, apoptosis rate, lactate production, and glucose uptake were measured in HCC cell lines with genistein incubation...
