[Three-dimensional finite element analysis of lumbar disc herniation under different body positions].

Objective: To campare biomechanical effects of different postural compression techniques on three-dimensional model of lumbar disc herniation (LDH) by finite element analysis.

Methods: Lumbar CT image of a 48-year-old female patient with LDH (heighted 163 cm, weighted 53 kg) was collected. Mimics 20.

Association of serum fibroblast growth factor 19 levels with arteriosclerosis parameters assessed by arterial stiffness and atherogenic index of plasma in patients with type 2 diabetes.

Background: The role of serum fibroblast growth factor 19 (FGF19) in arteriosclerosis is not well known. In the present study, we aimed to explore whether serum FGF19 levels were related to arteriosclerosis parameters, including arterial stiffness and atherogenic index of plasma (AIP), in patients with type 2 diabetes (T2D).

Methods: A total of 200 patients with type 2 diabetes and 50 healthy controls were recruited for this study from Apr 2017 to Oct 2018.

Serum fibroblast growth factor 19 and endogenous islet beta cell function in type 2 diabetic patients.

Background: Fibroblast growth factor 19 (FGF19) takes part in maintaining the balance of glycolipids and may be involved in regulating the secretory activity of islet beta cells in patients with type 2 diabetes. This study aimed to evaluate the relationship between the levels of serum FGF19 and endogenous islet beta cell function in type 2 diabetic patients.

Methods: Samples were obtained from 271 subjects: 85 drug-naïve type 2 diabetes participants exclusively on lifestyle intervention (N-DM group), 122 type 2 diabetes subjects previously used medications (DM group) and 64 normal controls (NC group).

Minimally Invasive Versus Traditional Open Transforaminal Lumbar Interbody Fusion for the Treatment of Single-Level Spondylolisthesis Grades 1 and 2: A Systematic Review and Meta-Analysis.

Objective: To compare the clinical efficacy and safety between minimally invasive and traditional open transforaminal lumbar interbody fusion in the treatment of single-level spondylolisthesis grades 1 and 2.

Methods: This was a systematic review and meta-analysis. A comprehensive literature retrieval was performed in 3 electronic databases (PubMed, Embase, and Cochrane library).

[Prediction of fetal hypoxia by measuring middle cerebral and umbilical artery resistance index in fetuses with umbilical cord around the neck in late pregnancy].

Objective: To investigate the value of middle cerebral artery (MCA) and umbilical artery (UA) resistance index in predicting fetal hypoxia in fetuses with umbilical cord around the neck in late pregnancy.

Methods: Eighty normal fetuses between 38 and 40 weeks of gestation and 88 fetuses with umbilical cord around neck were measured for MCA and UA pulsatility index (PI), resistance index (RI) and the peak-systolic/diastolic ratio (S/D) by means of color Doppler ultrasonography, and the resistance index ratio was calculated. Fetuses with umbilical cord around neck were estimated according to the measured normograms for the presence of fetal hypoxia, and the results were evaluated by diagnostic test.
