[Vesselplasty for the treatment of spinal metastases complicated by posterior wall destruction of vertebral body].

Objective: To evaluate the early clinical efficacy and safety of vesselplasty for the treatment of spinal metastases complicated by posterior wall destruction of vertebral body.

Methods: The clinical data of 19 patients(21 segments) with spinal metastases complicated by posterior wall destruction of vertebral body treated from January 2016 to January 2017 were retrospectively analyzed. There were 15 males and 4 females, aged 40 to 85 years old with a mean of (66.

Variability of glomerular filtration rate estimation equations in elderly Chinese patients with chronic kidney disease.

Background: Chronic kidney disease (CKD) is recognized worldwide as a public health problem, and its prevalence increases as the population ages. However, the applicability of formulas for estimating the glomerular filtration rate (GFR) based on serum creatinine (SC) levels in elderly Chinese patients with CKD is limited.

Materials And Methods: Based on values obtained with the technetium-99m diethylenetriaminepentaacetic acid ((99m)Tc-DTPA) renal dynamic imaging method, 319 elderly Chinese patients with CKD were enrolled in this study.

How increased VEGF induces glomerular hyperpermeability: a potential signaling pathway of Rac1 activation.

Despite growing evidence for a pathogenic role of vascular endothelial growth factor (VEGF) in microvascular complications of diabetes, the underlying mechanism responsible for its detrimental effect remains unknown. In the current study, we hypothesized that some of the detrimental effects of VEGF on microvascular endothelial cells in the diabetic milieu stem from its aberrant signaling, which leads to perturbed tight junction assembly and increased endothelial permeability. Using an integrated in vitro approach, we investigated whether the effect of VEGF on endothelial cell permeability involves Rac1 GTPase activation and tight junction disassembly.

[Clinical control study of dialysates with different concentrations of calcium on blood pressure in patients under hemodialysis for prolonged period].

Objective: To investigate the changes in blood pressure in hemodialysis patients treated with low calcium dialysate or high calcium dialysate for long time.

Methods: Fifteen patients undergoing hemodialysis were enrolled in this study. High calcium dialysate (1.

[Clearance effect of different blood purification techniques on parathyroid hormone in renal function failure patients on maintenance hemodialysis].

Objective: To evaluate the effect of different blood purification techniques on serum parathyroid hormone (PTH) level in chronic hemodialysis (HD) patients with renal failure.

Methods: Ninety patients were randomly divided into three groups: absorption (AP) group, hemodiafiltration (HDF) group, and HD group. Patients in AP group received therapy with resin absorptive devices associated with HD, patients in HDF group received HDF, while patients in HD group received HD.

[Comparison of serum leptin clearance with different blood purification].

Objective: To compare the serum Leptin clearance efficiency with different blood purification treatment.

Methods: Thirty-one chronic end-stage renal failure hemodialysis (HD) patients (16 men, 15 women, mean age (54.0+/-11.
