The isolation, structural characterization and anti-osteosarcoma activity of a water soluble polysaccharide from Agrimonia pilosa.

A homogenous polysaccharide (APP), with a molecular weight of 120 kDa, was isolated from the dried aerial parts of Agrimonia pilosa. Gas chromatography (GC) and GC-MS analysis revealed that APP has a backbone of 1,3-linked Glcp and 1,3, 6-linked Glcp, and branched with 1-linked Glcp terminal along the main chain in a relative ratio of 2:1:1. We investigated the response of human osteosarcoma U-2 OS cells to APP treatment.

Cable pin system versus K-wire tension band fixation for patella fractures in Chinese Han population: A meta-analysis.

This meta-analysis compared the therapeutic effect of cable pin system (CPS) with K-wire tension band (KTB) in the treatment of patella fractures among Chinese Han population. The databases of PubMed, Cochrane library, China National Knowledge Infrastructure (CNKI), Chinese WanFang and Chinese VIP were searched for studies on CPS versus KTB in the treatment of patella fractures among Chinese Han population. Literatures were screened according to the inclusion and exclusion criteria.

Bioinformatics analysis of fibroblasts exposed to TGF‑β at the early proliferation phase of wound repair.

The aim of the current study was to identify gene signatures during the early proliferation stage of wound repair and the effect of TGF‑β on fibroblasts and reveal their potential mechanisms. The gene expression profiles of GSE79621 and GSE27165 were obtained from GEO database. Differentially expressed genes (DEGs) were identified using Morpheus and co‑expressed DEGs were selected using Venn Diagram.

Is combined use of intravenous and intraarticular tranexamic acid superior to intravenous or intraarticular tranexamic acid alone in total knee arthroplasty? A meta-analysis of randomized controlled trials.

Background: Tranexamic acid (TXA) has been proven to be effective in reducing blood loss and transfusion rate after total knee arthroplasty (TKA) without increasing the risk of deep vein thrombosis (DVT) and pulmonary embolism (PE). Recently, an increasing number of studies have been interested in applying combined intravenous (IV) with intraarticular (IA) tranexamic acid in total knee arthroplasty. The purpose of this meta-analysis was to compare the blood loss and complications of combined TXA with IV TXA or IA TXA on TKA.

Intra-articular versus intravenous tranexamic acid application in total knee arthroplasty: a meta-analysis of randomized controlled trials.

Background: The purpose of this meta-analysis was to compare the blood loss and complications of intra-articular (IA) with intravenous (IV) tranexamic acid (TXA) for total knee arthroplasty (TKA).

Methods: A comprehensive search of studies was conducted to identify related articles in Pubmed, Embase, Cochrane central Register of Controlled Trials, springerLink, OVID and the Research published from January 1980 to September 2016. All studies that compared IA TXA with IV TXA application on TKA were included.

Z-plasty for severe gluteal muscle contracture in children.

Purpose: To review the records of 363 patients with severe gluteal muscle contracture to determine its mechanism, underlying pathology, and treatment outcome.

Methods: Records of 136 males and 227 females aged 5 to 18 (mean, 12.2) years who underwent Z-plasty for bilateral (n=347) or unilateral (n=16) severe gluteal muscle contracture were reviewed.

Treatment of chronic ulcer in diabetic rats with self assembling nanofiber gel encapsulated-polydeoxyribonucleotide.

Objective: This study aims to explore the treatment effects of chronic ulcer in diabetic rats with self assembling nanofiber gel encapsulated-polydeoxyribonucleotide.

Methods: Diabetic skin ulcer mouse model was established in this study. They were divided into control group, common wound group and infectious wound group.
