Treatment of senile lumbar spinal stenosis by unilateral approach and bilateral decompression with large channel endoscopy / 中国骨伤

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 (70.6± 8.4) years. The course of disease was from 1 to 12 years. All 32 cases were accompanied by numbness or pain in the lower limbs, of which 28 cases were accompanied by intermittent claudication. Narrow segments were L@*RESULTS@#All the patients were followed up for 12-24 (17.68±2.43) months and all operations were successfully completed with the operation time of 70-160(85.64±11.94) min. Spinal dural tear occurred in 1 case during the operation, and sensory disturbance in the other side of lower limb in a short period of time occurred in 2 cases, all improved after corresponding treatment. Postoperative imaging showed that the spinal canal was significantly enlarged and the nerve root was fully released. Before operation and 3 days, 3 months, 1 year after operation, VAS scores of low back pain were 4.62 ±1.41, 2.73 ±1.35, 1.21 ±1.17, 1.11 ±0.34, respectively;VAS scores of leg pain were 6.83 ± 1.71, 3.10±1.50, 1.08±0.19, 0.89±0.24, respectively. VAS scores of low back pain and leg pain each time point after operation were obvious improved (@*CONCLUSION@#It is a safe and effective way to treat lumbar spinal stenosis with unilateral approach and bilateral decompression via large channel endoscopic system. It has the advantages of sufficient decompression, less trauma, fast recovery, high safety and low incidence of postoperative complications. It can minimize the damage to the stable structure of the lumbar spine and is an ideal minimally invasive operation for the treatment of lumbar spinal stenosis.

Transforaminal percutaneous endoscopic lumbar discectomy combined with anchorage technique of pedicle for the treatment of high prolapse free lumbar disc herniation / 中国骨伤

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±7.2) years old. There were 1 case of L, 5 cases of L, 18 cases of L. The course of disease ranged from 8 to 26 months, with an average of (16.2±6.3) months. All the patients were subjected to local infiltration anesthesia. The clinical outcomes were evaluated by visual analog scale (VAS) for leg pain, low backpain and Oswestry Disability Index (ODI) at preoperative, first day after operation and 6 month after surgery. All data were statisticed by SPSS 22.0.@*RESULTS@#All the patients were followed up, and the duration ranged from 12 to 24 months, with a mean of (17.5±5.3) months. The average operation time was(69.8±14.2) minutes. One patient had cerebrospinal fluid leakage, which improved after supine rest. VAS scores of lower back pain were 6.36±1.27, 3.94±1.03, 1.62±0.87, 0.44±0.27, 0.37±0.29. VAS scores of leg pain were 8.28±1.74, 3.16±1.24, 2.83±1.13, 0.83±0.31, 0.46±0.31, and the differences were statistically significant (<0.05). The ODI were (48.79±9.83)%, (36.51±11.24)%, (21.05±6.35)%, (9.83±4.62)% and (7.24±4.72)% 1 day before and 1 weeks, 3 months, 6 months and 1 year after the operation, respectively. One year after the operation, the modified Macnab evaluation system was used to evaluate the clinical efficacy of the patients, 19 patients got an excellent result, 3 good, 2 fair and 0 poor.@*CONCLUSION@#Percutaneous endoscopic pedicle anchoring technique for the treatment of high prolapse free lumbar disc herniation can effectively improve the clinical symptoms of patients, and has the advantages of less trauma, less bleeding, rapid recovery, complete removal of the nucleus pulposus, and less pain of patients, etc., its clinical efficacy is accurate, operability is strong, it is worth promoting in the clinical use.

Long non-coding RNA for metabolism of bone tissue / 中国骨伤

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. In recent years, a large number of researche showed that LncRNA plays an important role in metabolism of bone and cartilage, and proved LncRNA participates in development and conversion of bone metabolism. With the exposure of function chennel and target of LncRNA, the key role of LncRNA in bone metabolism were proved constantly. The paper concluded biological characteristics of LncRNA, function and target spot of LncRNA in bone and cratilage metabolism, and in further state gene regulatory mechanism of bone and cartilage metabolism, explore diagnosis and treatment, provide new thought and treatment target for bone metabolism.
