Potential molecular mechanism of the Xiexin capsule in the intervention of dyslipidemia based on bioinformatics and molecular docking.

Objective: bioinformatic methods and molecular docking technology were used to predict the active components, targets, and related biological pathways of the Xiexin capsule in the intervention for dyslipidemia, exploring its mechanism. Methods: the active components and targets of the Xiexin capsule were screened by the TCMSP (Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform )database. Genecards (The Human Gene Database), OMIM (Online Mendelian Inheritance in Man), PharmGkb (Pharmacogenomics Knowledge Base database), TTD (Therapeutic Target Database), and Drugbank platforms were used to search the disease targets of dyslipidemia.

LncRNA SNHG14 accelerates breast cancer progression through sponging miR-543 and regulating KLF7 expression.

Purpose: Dysregulation of long non-coding RNAs (lncRNAs) is being found to have relevance to human cancers, including breast cancer (BC). The aim of this study was to further explore the functional role and molecular mechanisms of small nucleolar RNA host gene 14 (SNHG14) on BC progression.

Methods: The expression levels of SNHG14, miR-543, and krüppel-like factor 7 (KLF7) mRNA were determined by quantitative real-time PCR.

[Poking reduction cannulated screw for the treatment of SandersⅡ calcaneal fracture].

Objective: To evaluate clinical effect of poking reduction cannulated screw based on Pingle orthopedic muscle-bone interoperability balance theory in treating Sanders Ⅱ calcaneal fracture.

Methods: From October 2014 to December 2017, 28 patients with Sanders Ⅱ calcaneal fracture were treated with poking reduction cannulated screw guided by Pingle orthopedic muscle-bone interoperability balance theory, including 20 males and 8 females, aged from 24 to 55 years old with an average of (37.2±3.

Therapeutic evaluation of acupoint stimulation with needle-scapelon on rat model of degenerative cervical intervertebral discs.

Cervical spondylosis (CS), which is resulted from degeneration of cervical intervertebral disc, is a common disease seriously threatening human health and quality of life. However, there is still no effective clinic strategies for the treatment of this disease. The acupoint stimulation with needle-scalpel is a widely used approach to treat orthopedic diseases.

Altered methylation of glucosylceramide synthase promoter regulates its expression and associates with acquired multidrug resistance in invasive ductal breast cancer.

Overexpression of glucosylceramide synthase (GCS) increases multidrug resistance (MDR) in many cancer cells. However, its mechanism is unknown. The aim of the present study is to detect the association of methylation at the GCS gene promoter with its expression and MDR in invasive ductal breast cancer.

[Effect of Acupotomy Lysis at Cervical Acupoints on Expression of Matrix Metalloproteinases and Tissue Inhibitor of Metalloproteinase 1 and Changes of Pulpiform Nucleus Ultrastructure in Rats with Degenerated Cervical Intervertebral Discs].

Objective: To observe the effect of acupotomy lysis at acupoints around the neck on expression of matrix metalloproteinase 1 (MMP-1), MMP-2 and tissue inhibitor of metalloproteinase 1 (TIMP-1) genes and ultrastructure of pulpiform nucleus in cervical intervertebral disc degeneration (IVDD) rats, so as to explore its mechanism underlying easing IVDD.

Methods: SD rats were randomly allocated to control (n = 15), model (n = 14), Jiaji (EX-B 2, n = 13), cervico-acupoint (n = 14) and medication groups (n = 14). The cervical IVDD model was established by using static-dynamic imbalance method.

[Effect of Acupotome Relaxing on Expression of Type I and II Collagens of Degenerative Cervical Inter- vertebral Discs in Rats].

Objective: To observe the effect of acupotome relaxing at cervical acupoints on type I and II collagens of degenerated cervical intervertebral discs in rats, so as to explore its potential mechanism underlying anti-degeneration of intervertebral discs.

Methods: Rats were randomly divided into control, model, Jiaji acupoints, cervical acupoints and medication groups (n = 15 in each group). The rat model of cervical intervertebral disc degeneration due to static-dynamic imbalance was made as previously specified.

How do I implement a more restrictive transfusion trigger of hemoglobin level of 7 g/dL at my hospital?

Background: The red blood cell (RBC) transfusion trigger is a major driver of transfusion practice and affects health care costs and in some instances patient outcomes. Reducing the transfusion threshold will decrease RBC utilization and hospital costs.

Study Design And Methods: The hospital transfusion committee, endorsed by the medical staff executive committee, developed an educational program for physicians, nurses, and blood bank staff focusing on the scientific basis for a transfusion trigger of hemoglobin (Hb) of 7 g/dL rather than 8 g/dL as well as a program to discourage the routine 2-unit RBC transfusion.

[Current research of the excessive lateral pressure syndrome of patellofemoral joint].

As modern medicine getting deeply to understand ever-detailed anatomy,structure and animal mechanics of the patellofemoral joint, excessive lateral pressure syndrome, a very common patellofemoral disorder, has been reacquainted by the clinicians. On account to the complexity and variety of the etiology and the mechanism of the pain, still, there are many difficulties and arguments on the exact description of the clinical symptoms and the establishment of a universally accepted diagnostic criteria. Accurately grasping different causes, pathomechanisms and developmental stages of the disease would be especially important.

Characterization of MHC/peptide complexes refolded by a one-step ion-exchange chromatography.

The current refolding process of MHC/peptide complexes is low-yield and time-consuming, thereby limiting the wide uses of MHC/peptide multimers. Here the heavy chain protein of MHC/peptide complex (H-2K(b)/TRP2(180-188)) was immobilized onto an ion-exchange chromatography column, and the β2m or TRP2(180-188)-fused β2m protein, which renatured previously in refolding buffer, was able to pass through the column for the gradient refolding. This strategy refolds, concentrates and purifies MHC/peptide complexes in a single integrated step, achieving a high level of process simplification and automation.

Killer artificial antigen-presenting cells deplete alloantigen-specific T cells in a murine model of alloskin transplantation.

FasL-expressing killer antigen-presenting cells (KAPCs) have the ability to delete antigen-specific T cells and, therefore, could potentially be used for the treatment of allograft rejection and autoimmunity; however, their cellular nature markedly limits their clinical use. Novel bead-based killer artificial antigen-presenting cells (KaAPCs), which are generated by coupling major histocompatibility complex (MHC) class I antigens together with the apoptosis-inducing anti-Fas monoclonal antibody (mAb) onto magnetic beads, have recently attracted more attention. KaAPCs have a number of advantages over KAPCs and are able to deplete specific T cells in cocultures.
