Circ_0020123, a New Circular RNA Biomarker for Deep Vein Thrombosis in Pregnant Women.

Background: Deep vein thrombosis (DVT) commonly occurs among vascular diseases globally, for which circular RNAs (circRNAs) are becoming a promising option by mediating functions of human umbilical vein endothelial cells (HUVECs). Therefore, this study focuses on whether circ_0020123 plays a role in HUVECs.

Methods: Pregnant women with DVT (n = 39) and without DVT (n = 39) were selected as the observation group and control group, respectively.

Temporary pacemaker protected transjugular intrahepatic portosystemic shunt in a patient with acute variceal bleeding and bradyarrhythmia: A case report.

Background: Esophagogastric varices are a common complication of cirrhosis with portal hypertension and endoscopic treatment has been recognized as a primary preventive and therapeutic option for such patients; however, it should be noted that bradyarrhythmia is regarded as one of the contraindications to endoscopic examination. Meanwhile, acute variceal bleeding may result in a high mortality rate in cirrhotic patients with portal hypertension accompanied by bradyarrhythmia. At present, there is an absence of reports concerning the treatment of such group of patients who underwent transjugular intrahepatic portosystemic shunt (TIPS).

Computed Tomography-Based Evaluation of Volume and Position Changes of the Target Region and Organs at Risk During Radiotherapy for Esophageal Cancer: A Pilot Study.

Objective: To analyze changes in volume and position of target regions and organs at risk (OARs) during radiotherapy for esophageal cancer patients.

Methods: Overall, 16 esophageal cancer patients who underwent radiotherapy, including 10 cases of intensity-modulated radiation therapy (IMRT) and six of three-dimensional conformal radiotherapy (3D-CRT), were enrolled. The prescription doses for the planning target volumes (PTVs) were as follows: PTV1, 64 Gy/32 fractions; and PTV2, 46 Gy/23 fractions.

[Principles of "ecological living water" to purify sewage and its application in black and smelly water treatment of Yangzhou].

To explore the fundamental way of black and odorous water treatment, based on the study of the purification function of natural water body and the analysis of root cause and direct cause of black and odorous water body, we elaborated the scientific connotation and ecological function of "ecological living water", and fully revealed the scientific principle and technical advantages of "ecological living water" for sewage treatment. "Ecological living water" was the original ecological water control in situ. Through the rapid water reaeration, the micro-ecosystem of living water was created.

Bone marrow-derived mesenchymal stem cell transplantation ameliorates oxidative stress and restores intestinal mucosal permeability in chemically induced colitis in mice.

Background: Ulcerative colitis (UC) can be viewed as an autoimmune disease. Bone marrow-derived mesenchymal stem cells (MSCs) with its regenerative, cellular multi-lineage and immunomodulatory abilities can influence the repair of damaged tissues in UC. This study investigated the effects of MSCs transplantation on the mice intestinal barrier in response to oxidative stress injury.

The Effect of Flattening Filter Free on Three-dimensional Conformal Radiation Therapy (3D-CRT), Intensity-Modulated Radiation Therapy (IMRT), and Volumetric Modulated Arc Therapy (VMAT) Plans for Metastatic Brain Tumors from Non-small Cell Lung Cancer.

Flattening filter free (FFF) may affect outcome measures of radiotherapy. The objective of this study is to compare the dosimetric parameters in three types of radiotherapy plans, three-dimensional conformal radiation therapy (3D-CRT), intensity-modulated radiation therapy (IMRT), and volumetric modulated arc therapy (VMAT), with or without the flattening filter (FF), developed for the treatment of metastatic brain tumors from non-small cell lung cancer (NSCLC). From July 2013 to October 2013, 3D-CRT, IMRT, and VMAT treatment plans were designed using 6 MV and 10 MV, with and without FF, for 10 patients with brain metastasis from NSCLC.

[Study of the Raman spectrum of CCl4 Fermi resonance].

Fermi resonance is a very common phenomenon in molecule vibration spectra, especially in polyatomic molecule with complex structure. Fermi resonance appears when a fundamental vibration frequency lies closely to an overtone or combination frequencies. One can observe two peaks coming from Fermi resonance and the energy transfer also occurs between the two peaks.

[The distribution feature of TCR Vbeta repertoire in peripheral blood T cells from patients with Ph(+) and Ph(-) CML].

To investigate the T cell distribution characters of TCR Vbeta repertoire in Ph(+) and Ph(-) CML. The 24 subfamilies of the TCR Vbeta genes were amplified in peripheral blood T cells from 13 patients with CML (Ph+ b3a2, 5 cases; Ph+ b2a2, 5 cases; Ph(-), 3 cases) by RT-PCR, to analyze the usage of Vbeta subfamilies in different CML patients. The results showed that the expression pattern of Vbeta repertoire was different in normal individuals and in patients with CML which only have part of Vbeta subfamily T cells.

[Study on clonal proliferation of TCR Vbeta subfamily T cells induced by AML-M(2a) cells in vivo and in vitro].

To observe the expression and clonal expansion of TCR Vbeta subfamily T cells induced by AML-M(2a) cells in vivo and in vitro, complementary determining region 3 (CDR3) of TCR beta with variable region genes was amplified by using RT-PCR in both peripheral blood mononuclear cells (PBMNC) and T cells from mixed lymphocyte and tumor culture (MLTC) from four AML-M(2a) patients. The positive products were further analyzed to identify the clonality of T cells by genescan. The results showed that the similarity distribution of TCR Vbeta subfamily T cells was found Vbeta in PBMNC and MLTC.
