Abstract
Background It is well established that discogenic low back pain (DLBP) is often caused by the inflammatory response during intervertebral disc degeneration (IDD). However, it remains unclear how inflammatory mediators such as Interleukin-6 (IL-6) are involved in discogenic pain caused by degeneration and intervertebral disc (IVD) metabolism. The purpose of this study is to study the relationship between IL-6 and Transmembrane protein 100 (TMEM100), and to analyze the different metabolites and metabolic pathways in various rat intervertebral discs by metabonomics. Methods We established a rat model of IDD-DLBP by disc punctures and PBS infusion to examine the rat pain behaviors. Intervertebral disc tissues were harvested for molecular biology experiments to explore the relationship between IL-6 and TMEM100. High-resolution mass spectrometry (HRMS) was performed for untargeted metabolomics, and nuclear magnetic resonance spectroscopy metabolomics (MRS) for differential metabolites and metabolic pathways. Results The results showed a significant decrease in vonFrey test, hot plate test and acetone test (P < 0.05). The expression of IL-6 and TMEM100 in DLBP model was significantly higher than that in sham control group and IDD discs without PBS infusion group (P < 0.05). There were 15 major contributing metabolites identified in the DLBP intervertebral discs through metabolomic studies, involving 6 major metabolic pathways. The main differential metabolites included nitric oxide (NO), ammonia, and lactic acid as the metabolic endpoints; and the differential metabolic pathways included the glycine-serine-threonine (Gly-Ser-Thr), which is gradually weakened with the progression of inflammation. Conclusion The change of TMEM100 expression mediated by il-6 is related to the Gly-Ser-Thr metabolic axis and plays an important role in the relief of discogenic pain.

Abstract
Lumbar disc herniation (LDH) is a commonly occurring disease, threatening human health and life quality. Lack of a gold standard of diagnosis has hindered the efficiency and efficacy of clinical therapy against LDH. Traditional Chinese medicine (TCM) has provided an experience-based but subjective diagnosis system for LDH, demanding objective evidence and explanation. In this study, we adopted a metabonomics approach using gas chromatography-mass spectrometry (GC-MS) to profile metabolic characteristics of LDH and its TCM subtypes. Plasma samples of 41 LDH patients and 25 healthy controls were collected. LDH patients were classified into two main subtypes, the reality syndrome and deficiency syndrome, according to TCM theory. By using multivariate statistical analysis and metabolism network analysis, we found diverse perturbations of metabolites in amino acid metabolism and carbohydrate metabolism, in which the amino acids (glutamic acid, aspartic acid, glycine, etc.) were up-regulated and a key carbohydrate metabolite (glucose 1-phosphate) was down-regulated. Few differences were found between the two TCM subtypes. Our findings reveal the metabolic disorders of LDH for the first time and demonstrate the feasibility of the metabonomics approach for LDH research but not for its TCM subtypes.

Abstract
STUDY DESIGN A retrospective study of spinal stenosis patients admitted to Assaf Harofeh Medical Center Orthopedic Departments. OBJECTIVE To assess any correlation between systemic disease and spinal stenosis. SUMMARY OF BACKGROUND DATA Lumbar stenosis is a common spinal disease with various etiologies. No findings have been reported correlating spinal stenosis incidence with background diseases, although diabetes mellitus (DM) has been found to play a role in intervertebral disc degeneration and spondylolisthesis. METHODS Hospitalization records of patients with spinal stenosis admitted to Assaf Harofeh Medical Center Orthopedic Departments between 1984 and 1993 were checked for background diseases, age, and sex. The data collected were statistically evaluated for any correlation between spinal stenosis and chronic diseases and compared with the data published by the "Israeli Bureau of Statistics" and Israel's largest Health Maintenance Organization's chronic disease survey. RESULTS Of 537 patients with spinal stenosis 57% (308) were males and (229) 43% females with an average age of 60+/-14 years. Diseases occurring with a high incidence were hypertension (HTN)-23.2% (compared with 7.8% in the general population), DM-13.6% (5.9%), ischemic heart disease (IHD)-11.9%, and hyperlipidemia-4.4%. Patients with spinal stenosis had no significant age and sex distribution difference compared with the general population and no such difference was found for patients suffering from HTN, IHD, or DM. Isolating the effect of DM on HTN and IHD revealed that HTN was a primary disease whereas IHD was secondary to DM with significant statistical validation (P=0.003). CONCLUSIONS To the best of our knowledge this is the first study linking spinal stenosis and DM or HTN. It was found that chronic diseases do not alter the natural age and sex distribution of spinal stenosis. The major question remaining concerns the biologic mechanism linking spinal stenosis and DM or HTN.

Abstract
Introduction. Various clinical conditions can cause low back pain, and in most cases it is of a degenerative origin. Degenerative disc disease is a common condition which affects young to middle-aged men and women equally. Changes in the mechanical properties of the disc lead to degenerative arthritis in the intervertebral joints, osteophytes, and narrowing the intervertebral foramen or the spinal canal. Pathophysiology. Degenerative cascade, described by Kirkaldy-Willis, is the widely accepted pathophysiologic model describing the degenerative process as it affects the lumbar spine in 3 phases. Diagnosis. There are two forms of low back pain secondary to degenerative disc disease: a) lumbalgia and b) lumbar radiculopathy. Limitation of movement, problems with balance, pain, loss of reflexes in the extremities, muscle weakness, loss of sensation or other signs of neurological damage can be found on physical examination. For accurate diagnosis, it is often necessary to combine clinical examination and sophisticated technology. Treatment. Coservative treatment consists of rest, physical therapy, pharmacological therapy and injection therapy. Physical rehabilitation with active patient participation is a key approach to treatment of patients with discogenic pain. Physical therapy, occupational therapy and kinesitherapy are important for improving muscle strength, endurance, and flexibility. Disc surgery is performed if surgical intervention is required. .

Abstract
Metabolite levels in cerebrospinal fluid from patients with lower back pain and/or sciatica caused by disc herniation or spinal stenosis were compared with levels in pain-free controls using proton magnetic resonance spectroscopy. Significant differences for several metabolites were found in patients with pain compared with controls. Most changes were found in the group with disc herniation, including reductions in glucose, alanine, and lactate, suggesting increased aerobic metabolism in this group. There was a significant reduction in the level of glucose in the group with spinal stenosis irrespective of whether the patients were compared with the whole control group (age-weighted) or with age-matched controls. Additionally, inositol and creatinine were reduced in patients with disc herniation. Inositol was also significantly reduced in the spinal stenosis group when age matched to controls. Insofar as the levels of pain recorded by the patients with lumbar pathology were similar in the two groups, it seems more likely that the reductions in metabolite levels recorded in the group with disc herniations are related to disc pathology rather than the perception of pain. However, the possibility that pain perception contributes to the metabolic changes cannot be excluded.

Abstract
Degenerative disease of the spine is one of the most common clinical entities and affects the intervertebral discs, including opposing vertebral endplates, the intervertebral posterior joints and the ligaments. The most severe primary spinal degenerative changes are found in the lower cervical and lumbar spine regions. The spine contains three different types of joints, each of which presents its own pattern of degenerative disease: (i) cartilaginous joints, represented by the intervertebral disc or, more specifically, the functional unit defined as the 'vertebro-disc connection'; (ii) synovial joints, represented by the posterior intervertebral joints, sacro-iliac and costovertebral joints; (iii) fibrous joints, mainly found in the principal ligaments such as the posterior longitudinal ligament and the yellow ligaments. With regard to radicular pain, root compression alone does not fully account for root pain following disc-root conflict, but it is, nevertheless, considered to be the main cause of pain. We will try to explain that the origin of pain is multi-factorial and that inflammation probably predominates over merely mechanical mechanisms. To conclude, we will consider whether vertebral arthrosis can be construed as the body's decision to favour the spine's static function over its dynamic role when joint 'hypermobility' linked to chronic load in old age could cause severe structural damage to the bony vertebral structures. This hypothesis should also embrace a further concept: ageing of the spine is not merelychronological. Themostaccurate interpretation tha tcan account for similar degenerative phenomena encountered in the young is that of abnormal static and dynamic loading stress.
