Diagnostic features and therapeutic strategies for malignant paraganglioma in a patient: A case report.

Background: Paragangliomas and extra-adrenal pheochromocytomas are uncommon neuroendocrine tumors with ubiquitous distribution. Malignant paraganglioma is a relatively rare entity. We report the treatment and pathological characteristics of a patient with malignant paraganglioma, and summarize the latest advances in the treatment of malignant paraganglioma based on a literature review.

Effects of dietary Enteromorpha powder on reproduction-related hormones and genes during the late laying period of Zi geese.

Objective: The aim of this study was to investigate the effects of Enteromorpha powder supplementation on reproduction-related hormones and genes in the late laying period of Zi geese.

Methods: A total of 312 (1-year-old) Zi geese with similar laying rate were randomly divided into 2 groups with 6 replicates each, each with 21 female geese and 5 male geese. The control group was fed with a basal diet and the test group was fed with a diet containing 3% Enteromorpha powder.

Nomogram predicting overall survival of rectal squamous cell carcinomas patients based on the SEER database: A population-based STROBE cohort study.

We aimed to evaluate the prognostic value of clinical and pathologic factors in rectal squamous cell carcinomas (SCC) and to construct a nomogram for their outcome prediction.The study cohort was selected from Surveillance, Epidemiology, and End Results (SEER) program between January 2004 and December 2013. Univariate and multivariate analyses were performed using Cox proportional hazards regression model to evaluate the prognostic value of involved variables.

Identification of antioxidant activity of two new aromatic ring butyrolactone derivatives from Dictamnus dasycarpus Turcz.

The present study carried out a phytochemical investigation on the root barks of Dictamnus dasycarpus Turcz, leading to the isolation and characterization of two new aromatic ring butyrolactone derivatives, dasycarpusphenol acid A (1) and dasycarpusphenol acid B (2). Their structures were elucidated by using spectroscopic techniques and HR-FAB-MS. Compounds 1 and 2 exhibited antioxidant activity, with their IC values being 28.

ST3Gal III modulates breast cancer cell adhesion and invasion by altering the expression of invasion-related molecules.

Changes in the carbohydrate structure on the surface of tumor cells is an important feature of cancer metastasis. The specific role of sialic acids in the glycoconjugate terminal has not yet been clearly elucidated in these processes. Previously, we reported that α2,3-sialic acid residues in breast cancer are associated with metastatic potential.

[Effect of lupeol on migration and invasion of human breast cancer MDA-MB-231 cells and its mechanism].

In this study, we examined the inhibitory effects of lupeol, an extract of Euphorbia fischerana Steud, on human breast cancer MDA-MB-231 cells migration and invasion. Lupeol was found to inhibit the invasion of MDA-MB-231 in the cell adhesion assay, transwell test and wound healing assay. The expression of cyclooxygenase-2 (COX-2), matrix metalloproteinase-2 (MMP-2), -9 (MMP-9) and nuclear transcription factor-kappa B (NF-κB) p65 in breast cancer following treatment with different concentrations of lupeol was analyzed with Western blot.

[Therapeutic effects and mechanisms of Opuntia dillenii Haw on atherosclerosis of rats].

The research aimed to investigate the therapeutic effects and mechanisms of Opuntia dillenii Haw polysaccharide (OPS) on atherosclerosis of rats. First atherosclerotic rat models were established by high-fat and high-calcium diet. Thirty days later, the rats were treated with low dosage of OPS (0.

[Effect of ethyl gallate on invasion abilities and its mechanism of breast cancer MDA-MB-231 cells].

This study is to investigate the effect of ethyl gallate on invasion capabilities and its mechanism of breast cancer MDA-MB-231 cells. Using cell adhesion and transwell assay, separately, the effects of ethyl gallate on the invasion of MDA-MB-231 cells were measured. The Akt-NF-κB signal pathway protein expressions were analyzed with Western blot.

Low-dose cytarabine and aclarubicin combined with granulocyte colony-stimulating factor for the treatment of relapsed or primary refractory acute lymphocytic leukemia: a retrospective study of 25 Chinese patients.

Despite improvements in treatment, the prognosis of relapsed or primary refractory acute lymphocytic leukemia (ALL) remains poor, and outcomes are worse in older adults with the short first complete remission (CR). Attainment of the second CR by salvage therapy would improve the survival of these patients and may enable them to undergo curative treatment with allogeneic hematopoietic stem cell transplantation. The fact that there are diverse salvage protocols for these adult patients but without a striking CR-induction efficacy indicates that efforts are still needed to indentify new effective reinduction regimens.

Discrete water clusters in tetra-μ-cyanido-tetra-cyanidobis(1,4,7-triisopropyl-1,4,7-triaza-cyclo-nona-ne)dicopper(II)dinickel(II) tetra-hydrate.

The title tetra-cyanido-nickelate-copper complex, [Cu₂Ni₂(CN)₈(C₁₅H₃₃N₃)₂]·4H₂O, was synthesized by self-assembly using potassium tetracyanidonickelate(II) and dichlorido(1,4,7-triisopropyl-1,4,7-triazacyclononane)copper(II). The asymmetric unit contains half of a complex mol-ecule and two water mol-ecules. The entire complex has -1 symmetry and contains Ni(II) in a slightly distorted square-planar and Cu(II) in a square-pyramidal coordination environment.

Immunostimulatory activities of a low molecular weight antitumoral polysaccharide isolated from Agaricus blazei Murill (LMPAB) in Sarcoma 180 ascitic tumor-bearing mice.

LMPAB is a linear beta-(1-3)-glucan we isolated from polysaccharide extract of Agaricus blazei Murill (AbM). Effects of LMPAB on splenic natural killer (NK) cell activity, splenocyte proliferation, index of spleen and thymus, IFN-gamma expression in spleen and the concentration of IL-12, IL-18 and TNF-alpha in serum of S180 ascitic tumor-bearing mice were detected. The results showed that intraperitoneal injection of LMPAB (100 mg x kg(-1) x d(-1)) significantly increased the thymus index.
