[Treatment of senile lumbar spinal stenosis by unilateral approach and bilateral decompression with large channel endoscopy].

Objective: To evaluate clinical effect of unilateral approach and bilateral decompression via large channel endoscopic system for the treatment of lumbar spinal stenosis.

Methods: The clinical data of 32 patients with lumbar spinal tenosis treated by unilateral approach and bilateral decompression via large channel endoscopy from February 2018 to February 2019 were retrospectively analyzed. There were 18 males and 14 females, aged 65 to 84 years old with an average of (70.

Posterior percutaneous endoscopic versus traditional surgery for cervical disc herniation: A protocol for systematic review and meta analysis.

Background: Posterior percutaneous endoscopic cervical diskectomy (P-PECD) can be used posterior microdiscectomy for cervical disc herniation. But only some small sample sizes of clinical studies have evaluated the efficacy and safety of P-PECD. This study aim to evaluated the efficacy and safety of P-PECD compared with traditional open surgery.

[Transforaminal percutaneous endoscopic lumbar discectomy combined with anchorage technique of pedicle for the treatment of high prolapse free lumbar disc herniation].

Objective: To investigate the clinical effects of percutaneous spinal endoscopy (percutaneous endoscopy) in the treatment of high prolapse free lumbar disc herniation.

Methods: From May 2016 to June 2018, 24 patients with highly prolapse free lumbar disc herniation were enrolled in this study, including 11 males and 13 females, ranging in age from 48 to 72 years old, with an average of (59.5±7.

[Long non-coding RNA for metabolism of bone tissue].

The mechanism of metabolism of bone and cartilage are one of focus of orthopedic knowledge, and its clinical and basic study plays an important role in preventing and treating osteoporosis, degeneration of bone and joint, bone tumor. At present, the mechanism of metabolism of bone and cartilage studied from protein, signal pathway to mRNA transcription factor regulation. As a new regulatory factor for non-coding proteins, long non-coding RNA(LncRNA) participates in physiological and pathological process.
