Background: There is still a risk of refracture of the contralateral hip after total hip replacement, to analyze the expression of C-reactive protein (CRP) and albumin (Alb) in elderly patients with contralateral hip refracture after total hip arthroplasty (THA), and to determine its correlation with the risk of post-surgery refracture and guide the prediction of the risk of contralateral hip fracture in the future.

Methods: The medical records of elderly patients who suffered hip fracture and underwent THA at our hospital between July 2016 and July 2019 were reviewed, and 224 eligible patients were finally enrolled. The patients were divided into the refracture group and the control group according to the incidence of contralateral hip refracture.

Repair of segmental bone defects is a challenge in orthopaedics. A bone substitute is a potential solution for this challenge, and angiogenesis and osteogenesis are critical to the performance of scaffold materials. For enhancing angiogenesis and osteogenesis activities of implanted scaffolds, Cu/Zn co-doped calcium phosphate scaffolds carrying GDF-5-release microspheres were prepared and implanted into surgically created critical-sized rabbit radial defects.

Resistance mechanism exploration has become an urgent need owing to the widespread trastuzumab resistance in gastric cancer. In this study, UHPLC-Q exactive MS/MS was carried out to characterize the metabolic profiles of human gastric cancer cell lines NCI N87, MKN45 (trastuzumab-sensitive) and NCI N87/R, MKN45/R (trastuzumab-resistant), respectively. Metabolic signatures and different metabolites were identified using multivariate in combination with univariate analysis.

Polyetheretherketone (PEEK) is a promising alternative for biomedical metallic implants in orthopedic and dental applications because its elastic modulus is similar to that of bone. However, PEEK is a bioinert material that cannot be integrated with host bone. Our previous study showed surface phosphonation enhanced the osteogenic activity of PEEK.

Overexpression of B7-H3 as an opportunity for targeted therapy in head and neck cancers.

Am J Transl Res

August 2019

Department of Otolaryngology, Head and Neck Surgery, West China Hospital, West China Medical School, Sichuan University Chengdu, Sichuan, P. R. China.

Head and neck cancers (HNCs) are the sixth most common type of cancer in the world. Despite the development of refined surgical techniques and precise targeted radiation, patients with HNCs have a dismal prognosis. Here, we examine the expression profile of B7-H3 in HNCs and verify whether B7-H3 can serve as a novel therapeutic target for HNCs via anti-B7-H3×CD3 bispecific antibodies (biAbs).

The purpose of this meta-analysis was to investigate the antidepressant effects of repetitive transcranial magnetic stimulation (rTMS) over the prefrontal cortex (PFC) of patients with Parkinson's disease (PD) and to determine the optimal rTMS parameters, such as the intensity, frequency and the delivered pattern of rTMS stimulation. EMBASE, PubMed, Web of Science, MEDLINE, and Cochrane data bases were researched for papers published before March 12, 2018. Studies investigating the anti-depression effects of rTMS over PFC in patients with PD were considered.

Septic acute kidney injury (AKI) characterized as acute infection and renal inflammation, still lacks of effective therapies. Isoliquiritigenin (ISL) as a small molecular from licorice, is able to inhibit the expression of HMGB1. However, the role and mechanism of ISL in septic AKI has not been investigated.

Tissue-engineered intervertebral discs (IVDs) have been proposed as a useful therapeutic strategy for the treatment of intervertebral disc degeneration (IDD). However, most studies have focused on fabrication and assessment of tissue-engineered IVDs in small animal models and the mechanical properties of the scaffolds are far below those of native human IVDs. The aim of this study was to produce a novel tissue-engineered IVD for IDD regeneration in the porcine lumbar spine.

Despite the great potential of numerous antioxidants for pharmacotherapy of diseases associated with inflammation and oxidative stress, many challenges remain for their clinical translation. Herein, a superoxidase dismutase/catalase-mimetic material based on Tempol and phenylboronic acid pinacol ester simultaneously conjugated β-cyclodextrin (abbreviated as TPCD), which is capable of eliminating a broad spectrum of reactive oxygen species (ROS), is reported. TPCD can be easily synthesized by sequentially conjugating two functional moieties onto a β-cyclodextrin scaffold.

Previous studies have reported excessive expression of apoptosis-antagonizing transcription factor (AATF) in various tumors, where it reinforces the generation and development of cancers and is linked to the clinical outcome. Nevertheless, the expression and influence of AATF in Wilms' tumor (WT) is largely unknown. Here, we discovered that AATF expression was markedly increased in WT tissues as compared to the surrounding normal tissues.

Research findings on the molecular mechanisms of epilepsy almost always originate from animal experiments, and the development of induced pluripotent stem cell (iPSC) technology allows the use of human cells with genetic defects for studying the molecular mechanisms of genetic epilepsy (GE) for the first time. With iPSC technology, terminally differentiated cells collected from GE patients with specific genetic etiologies can be differentiated into many relevant cell subtypes that carry all of the GE patient's genetic information. iPSCs have opened up a new research field involving the pathogenesis of GE.

Synthetic scaffolds with multifunctional properties, including angiogenesis and osteogenesis capacities, play an essential role in accelerating bone regeneration. In this study, various concentrations of Cu/Zn ions were incorporated into biphasic calcium phosphate (BCP) scaffolds, and then growth differentiation factor-5 (GDF-5)-loaded poly(lactide--glycolide) (PLGA) microspheres were attached onto the ion-doped scaffold. The results demonstrated that with increasing concentration of dopants, the scaffold surface gradually changed from smooth grain crystalline to rough microparticles, and further to a nanoflake film.
