Bone cancer pain (BCP) is a type of ongoing or breakthrough pain caused by a primary bone tumor or bone metastasis. BCP impairs patients' quality of life. Depending upon clinical observations, the administration of centrally acting analgesic has been associated with the alleviation of pain symptoms BCP patients.

To explore the role of the ceRNA regulatory network in the immune microenvironment of bladder cancer, whole-transcriptome sequencing of bladder tumor and its peritumoral tissues from 38 bladder cancer patients, with a total of 63 samples, was performed to screen differentially expressed circ-, lnc-, mi-, and mRNAs to construct a circ/lnc-mi-mRNA regulatory network with pruning algorithms. We excavated a key immune-related gene to build the final ceRNA network as hsa-miR-107 sponged by hsa-circ-000211, AC108488.

He complained of dysuria and recurrent urinary retention and was initially diagnosed with benign prostatic hyperplasia. Accidentally, a dark-brown pigmented macula was found in the distal urethra at the end of transurethral prostatectomy when we exited the resectoscope, transurethral resection of the nidus and sent to pathological examination showed the characteristics of melanoma.

In this work, a batch of novel ternary hybrids (SiC@C-FeO), characterized by SiC nanowires core, carbon shell, and adhered FeO nanoparticles were controllably synthesized via surface carbonization of SiC followed by hydrothermal reaction. Carbon, which was derived from SiC with nanometer thickness, possesses an amorphous structure, while FeO nanoparticles are in a crystalline state. Simultaneously, the inducement of FeO nanoparticles can provide significant magnetic loss, which is well-tuned by changing the molar content of iron precursors (FeCl·6HO and FeCl·4HO).

Material And Methods: 126 patients with single segment thoracolumbar vertebral fracture were surgically treated with percutaneous pedicle screws through our novel hand-held retractor technique(group A) or conventional fluoroscopic method(group B), the operation time and fluoroscopy shot times were compared, and the accuracy of screw placement were assessed.
Results: There was no serious complications occurring during our study, such as infection, blood vessel injury, spinal cord or nerve root injury.
Aim: To introduce a visual surgical concept using a retrospective comparison of the outcomes between visualized percutaneous endoscopic lumbar discectomy (V-PELD) and conventional PELD techniques.
Material And Methods: Data from 61 patients in the conventional PELD group and 55 in the V-PELD group. Data included the duration of the operation, number of intraoperative radiation exposure events, and follow-up information for 24 months.
Background: Sufficient decompression of the nerve root canal is still regarded as the method of choice when operating on patients with lumbar disc herniation (LDH) with lumbar lateral recess stenosis; however, tissue-sparing procedures are becoming more popular. Endoscopic techniques offer advantages and the benefits of rehabilitation, which have become the standard in many surgical operations when operating on the spine. A significant issue has been the upgrading of instruments to provide enough bone resection under continuous visual control.

PTKO model mice were administered with 150, 300 or 450 mg/kg myrtol for 8 weeks. ELISA analysis was used to measure tumor necrosis factor-α, interleukin-6, malondialdehyde, superoxide dismutase, reactive oxygen species and TGF-β1 levels.

Objective: To explore the effectiveness percutaneous monoaxial screw combined with polyaxial pedical screw for treating thoracolumbar fracture by comparing with simple polyaxial pedicle screw fixation.
Methods: Between January 2012 and June 2014, 56 cases of thoracolumbar fractures were treated by percutaneous pedicle screw fixation, the clinical data were retrospectively analyzed. Of 56 cases, 30 were treated with percutaneous monoaxial screw combined with percutaneous polyaxial pedical screw fixation (group A), 26 patients with only percutaneous polyaxial pedicle screw fixation (group B).
Background: Application of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) is limited by long fluoroscopy time and a steep learning curve. Herein, MI-TLIF was modified using a trans-multifidus approach, assisted by microscope, termed MMI-TLIF, and the clinical outcomes of MMI-TLIF and open-TLIF were compared.
Methods: Forty-nine patients treated with MMI-TLIF were matched with 49 subjects who underwent open-TLIF.

Recently, the main therapy of medullary thyroid cancer (MTC) is surgical, but by which way there is a poor prognosis with a mean survival of only 5 years. In some cases, some researchers found that it is the medullary thyroid cancer stem cells (MTCSCs) that cause metastasis and recurrence. This study aimed to eradicate MTCSCs through administration of all-trans-retinoic acid (ATRA).
