Circulating miR-107 as a diagnostic biomarker of osteoporotic vertebral compression fracture increases bone formation in vitro and in vivo.

Aims: This study aimed to examine the key circulating microRNAs (miRNAs) in the plasma of patients with osteoporotic vertebral compression fracture and assess their potential role as diagnostic biomarkers and explore their function in vitro and in vivo.

Methods: Weighted gene co-expression network analysis (WGCNA) was applied to identify hub miRNAs for subsequent analysis. The candidate miRNAs were tested using plasma from 144 patients and the results were applied to construct receiver operating characteristic (ROC) curves to assess their diagnostic value.

Effect of Particle Size Ratios on the Physical and Chemical Properties of Surgical-Grade Calcium Sulfate Hemihydrate.

Objectives: To analyze the optimum particle size or formula ratio of surgical-grade calcium sulfate (CS) for appropriate compressive strength, setting time, and vitro degradation rate.

Methods: Three types of calcium sulfate hemihydrate (CSH) particles with diameters of 0-37.5 μm, 37.

Long-term Results Comparing Cervical Disc Arthroplasty to Anterior Cervical Discectomy and Fusion: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Objective: Whether cervical disc arthroplasty (CDA) is superior to anterior cervical discectomy and fusion (ACDF) remains controversial, especially in relation to long-term results. The present study aimed to evaluate the long-term safety and efficiency of CDA and ACDF for cervical disc disease.

Methods: We performed this study according to the Cochrane methodology.

Posterior Cervical Foraminotomy Via Full-Endoscopic Versus Microendoscopic Approach for Radiculopathy: A Systematic Review and Meta-analysis.

Background: Recently posterior cervical foraminotomy (PCF) performed using a minimally-invasive surgery (MIS) approach for cervical radiculopathy due to lateral disc herniation or osseous foraminal stenosis has gained popularity. As 2 dominating MIS techniques, whether FE-PCF or MI-PCF provides superior clinical outcomes remains controversial.

Objectives: To compare clinical success rate, overall incidence of complications and reoperation rate between full-endoscopic posterior cervical foraminotomy (FE-PCF) and microendoscopic posterior cervical foraminotomy (MI-PCF) for cervical radiculopathy.

[Application of enzyme-labeled probe in testing of transgenic plant].

Used alkaline-phosphatase-labeled DNA as a probe to examine the expression of foreign UidA gene in transgenic plants. Alkaline phosphatase coupled with polyethyleneimine (PEI) using P-benzoquine as the cross-linking reagent was covalently linked to single-stranded DNA via glutraldehyde. Such DNA-enzyme complexes were used as a probe for dot hybridization and Southern blot.

The comparison of twinning rates between urban and rural areas in China.

Based on the birth record data from the National Vital Statistics in the 1990 Census of China, the present study analyzed the differences between urban and rural areas on monozygotic (MZ) and dizygotic (DZ) twin rates by maternal age in 1989. The twins by zygosity were calculated with Weinberg's differential method. Results show that the MZ and DZ twinning rates in China were associated with maternal age and that there were substantial differences between urban and rural areas.
