Methods A total of 69 patients undergoing vertebral pulp extraction were randomized into acupuncture group ( n = 35) and control group ( n = 34). Patients of acupuncture group were treated with routine rehabilitation method and electroacupuncture (EA) stimulation on Zhìbiān (秩边 BL54) and Wěizhōng (委中 BL40), acupuncture on Shènshū ( 肾俞 BL23), Dàchángshū (大肠俞 BL25), BL54, BL40, Jiájǐ (夹脊 EX-B 2), Shàngliáo (上髎 BL31), etc., and cupping on BL40, with 15 days being a therapeutic course and for average 7. 36 courses. Patients of control group were treated with simple rehabilitation method. Functional recovery state was judged before and after surgery by using the standards of Japanese Orthopedic Association (JOA). Results The average recovery rates of 3 months, 6 months and one year after surgery were 49.93% ,90.31% and 95.08% separately in acupuncture group, and 26.24% ,63.42% and 71.36% successively in control group. The recovery rates of acupuncture group were significantly higher than those of control group at the same time-points (P〈0. 05). Conclusion Acupuncture has a definite effect on promoting post-operative functional recovery in LIDP patients undergoing vertebral pulp extraction and spinal fusion.展开更多

In observation group, body acupuncture was applied on Ahshi points of lumbar region, lumbar Jiájǐ (夹脊EX-B 2), Dàchángshú(大肠俞 BL 25), etc. and wrist-ankle acupuncture was applied on lower No. 4, 5 and 6 regions. In control group, simple body acupuncture was applied on the same points as observation group. Results The lumbar vertebral function and pain scale were improved in either group in comparison before and after treatment (P〈0.05). Concerning pain improvement, the total effective rate was 95.6% in observation group, which was superior to that (86.7%) in control group (P〈0.05). Concerning the improvement of lumbar vertebral function, the total effective rate was 90.0% in observation group and 93.3% in control group, without significant difference between two groups (P〉0.05). Conclusion Combined therapy of body acupuncture and wrist-ankle acupuncture demonstrates apparent analgesia in prolapse of lumbar intervertebral disc.展开更多

METHODS: The databases of PubMed, China Na- tional Knowledge Infrastructure (CNKI), Chinese Sci- entific Journals Database (VlP), Chinese Biomedical Literature Database (CBM) and Chinese Medical Ci- tation Index (CMCl) were searched up to January 30, 2012. Randomized controlled trials were select- ed to compare Duhuojisheng Tang with one ormore of the following treatments: traction, acu- puncture, massage, cupping and Western medical treatment. The quality-evaluating standard and the software RevMan 5.1 in Cochrane coordinative net were used to analyze the data. The effective index- es of the results were clinical curative rate, effective- ness of alleviating clinical symptoms and adverse reaction. RESULTS: Thirty-one randomized controlled trials of low quality, involving 3915 patients were system- atically evaluated. Statistical analyses showed that good curative effect was achieved in both the group using Duhuojisheng Tang alone and with combined therapies. CONCLUSION: Using Duhuojisheng Tang alone or combined with other therapies can effectively im- prove pain, leg-raising height and other clinical symptoms of patients with prolapse of lumbar in- tervertebral disc. Due to low methodological quali- ty of the articles, no exact recommendations can be made.展开更多

However,no appropriate animal model or objective evaluation index is available. This study aimed to investigate the features of intervertebral disc degeneration in aging process of rats. Methods:22-month-old Sprague-Dawley(SD) rats were used as spontaneously occurring intervertebral disc degeneration models and 6-month-old rats as young controls. Expression of collagen types II and X was measured by immunohistochemistry. Degenerations of intervertebral discs were scored according to Miyamoto's method. Numbers and areas of afferent vascular buds were measured. The thicknesses of non-calcified and calcified layers were measured and statistically analyzed. Results:There were less collagen type II expression and more collagen type X expression in the calcified layer of the cartilage endplates and nucleus pulposus in the rats of the aged group than in the young control. There were fewer and smaller afferent vascular buds in the rats of the aged group than in the young control group. The ratio of the non-calcified to the calcified layers in the rats of the aged group significantly decreased,compared with that of the young control group(P<0.01) . Conclusion:Rats can spontaneously establish intervertebral disc age-related degeneration. The expression of collagen types II and X,numbers and areas of afferent vascular buds,the ratio of the non-calcified to the calcified layers,and water and glycosaminoglycan contents in the nucleus pulposus are sensitive indexes of intervertebral disc degeneration.展开更多

文摘Aging is a pivotal risk factor for intervertebral disc degeneration(IVDD)and chronic low back pain(LBP).The restoration of aging nucleus pulposus cells(NPCs)to a youthful epigenetic state is crucial for IVDD treatment,but remains a formidable challenge.Here,we proposed a strategy to partially reprogram and reinstate youthful epigenetics of senescent NPCs by delivering a plasmid carrier that expressed pluripotency-associated genes(Oct4,Klf4 and Sox2)in Cavin2-modified exosomes(OKS@M-Exo)for treatment of IVDD and alleviating LBP.The functional OKS@M-Exo efficaciously alleviated senescence markers(p16^(INK4a),p21^(CIP1)and p53),reduced DNA damage and H4K20me3 expression,as well as restored proliferation ability and metabolic balance in senescent NPCs,as validated through in vitro experiments.In a rat model of IVDD,OKS@M-Exo maintained intervertebral disc height,nucleus pulposus hydration and tissue structure,effectively ameliorated IVDD via decreasing the senescence markers.Additionally,OKS@MExo reduced nociceptive behavior and downregulated nociception markers,indicating its efficiency in alleviating LBP.The transcriptome sequencing analysis also demonstrated that OKS@M-Exo could decrease the expression of age-related pathways and restore cell proliferation.Collectively,reprogramming by the OKS@M-Exo to restore youthful epigenetics of senescent NPCs may hold promise as a therapeutic platform to treat IVDD.

文摘Intervertebral disc degeneration is a major risk factor contributing to chronic low back and neck pain.While the etiological factors for disc degeneration vary,age is still one of the most important risk factors.Recent studies have shown the promising role of SIRT6 in mammalian aging and skeletal tissue health,however its role in the intervertebral disc health remains unexplored.We investigated the contribution of SIRT6 to disc health by studying the age-dependent spinal phenotype of mice with conditional deletion of Sirt6 in the disc(AcanCreERT2;Sirt6fl/fl).Histological studies showed a degenerative phenotype in knockout mice compared to Sirt6fl/fl control mice at 12 months,which became pronounced at 24 months.RNA-Seq analysis of NP and AF tissues,in vitro quantitative histone analysis,and RNA-seq with ATAC-seq multiomic studies revealed that SIRT6-loss resulted in changes in acetylation and methylation status of specific Histone 3 lysine residues and affected DNA accessibility and transcriptomic landscape.A decrease in autophagy and an increase in DNA damage were also noted in Sirt6-deficient cells.Further mechanistic insights revealed that loss of SIRT6 increased senescence and SASP burden in the disc characterized by increased p21,p19,γH2AX,IL-6,IL-1β,and TGF-βabundance.Taken together,our study highlights the contribution of SIRT6 in modulating DNA damage,autophagy,and cell senescence and its importance in maintaining disc health during aging,thereby underscoring it as a potential therapeutic target to treat intervertebral disc degeneration.

文摘Intervertebral disc degeneration(IVDD)is the primary contributor to a range of spinal diseases.Dynamin-related protein 1(Drp1)-mediated mitochondrial fission has recently been identified as a new cause of nucleus pulposus cell(NPC)death and IVDD,but the underlying mechanisms remain unclear.Although the effects of Drp1 phosphorylation in IVDD have been studied,it is currently unknown if small ubiquitin-like modifications(SUMOylation)of Drp1 regulate IVDD.This study aimed to investigate the functions and mechanisms of mitochondria-anchored protein ligase(MAPL),a mitochondrial SUMO E3 ligase,during IVDD progression.The expression of genes related to SUMOylation and mitochondrial dynamics in TNF-α-stimulated NPCs was analysed via RNA sequencing.

文摘Intervertebral disc degeneration(IDD)is a progressive and dynamic process in which the senescence-associated secretory phenotype(SASP)of nucleus pulposus cells(NPC)plays a significant role.While impaired chaperone-mediated autophagy(CMA)has been associated with inflammation and cellular senescence,its specific involvement in the self-perpetuating feedback loop of NPC senescence remains poorly understood.Through LAMP2A knockout in NPC,we identified a significant upregulation of DYRK1A,a core mediator of premature senescence in Down syndrome.Subsequent validation established DYRK1A as the critical driver of premature senescence in CMA-deficient NPC.Combinatorial transcription factor analysis revealed that under IL1B stimulation or CMA inhibition,elevated DYRK1A promoted FOXC1 phosphorylation and nuclear translocation,initiating transcriptional activation of cell cycle arrest.Intriguingly,CMA impairment concurrently enhanced glutamine metabolic flux in senescent NPC,thereby augmenting their survival fitness.Transcriptomic profiling demonstrated that CMA reactivation in senescent NPC facilitated fate transition from senescence to apoptosis,mediated by decreased glutamine flux via GLUL degradation.Therefore,CMA exerts protective effects against IDD by maintaining equilibrium between premature senescence and senolysis.This study elucidates CMA’s regulatory role in SASP-mediated senescence amplification circuits,providing novel therapeutic insights for IDD and other age-related pathologies.

文摘Intervertebral disc degeneration(IDD)results from an imbalance within the intervertebral disc,leading to alterations in extracellular matrix composition,loss of nucleus pulposus cells,increased oxidative stress,and inflammatory cascade.While IDD naturally progresses with age,some factors such as mechanical trauma,lifestyle choices,and genetic abnormalities can elevate the risk of symptomatic disease progression.Current treatments,including pharmacological and surgical interventions,fail to halt disease progression or restore IDD function.Although biological therapies have been evaluated,their effectiveness in reversing long-term disc degeneration remains inconsistent.Mesenchymal stem cellbased therapies have demonstrated potential for IDD regeneration but are hindered by biological limitations,ethical issues,etc.To date,mesenchymal stem cell-derived extracellular vesicles(EVs)have emerged as promising therapeutic agents for regeneration and anti-inflammation.Their therapeutic effects are attributed to several mechanisms,such as the induction of regenerative phenotype,apoptosis mitigation,and immunomodulation.In addition,the abundance of microRNAs within EVs play a crucial role in modulating the disc degeneration.Due to the problems in clinical use,however,the efficiency of the EVs should be overcome further by optimizing cell culture conditions,engineering them to deliver drugs and targeting molecules,etc.
文摘In healthy intervertebral discs(IVDs),nerves and blood vessels are present only in the outer annulus fibrosus,while in degenerative IVDs,a large amount of nerve and blood vessel tissue grows inward.Evidence supports that neurogenic inflammation produced by neuropeptides such as substance P and calcitonin gene related peptide released by the nociceptive nerve fibers innervating the IVDs plays a crucial role in the process of IVD degeneration.Recently,non-neuronal cells,including IVD cells and infiltrating immune cells,have emerged as important players in neurogenic inflammation.IVD cells and infiltrating immune cells express functional receptors for neuropeptides through which they receive signals from the nervous system.In return,IVD cells and immune cells produce neuropeptides and nerve growth factor,which stimulate nerve fibers.This communication generates a positive bidirectional feedback loop that can enhance the inflammatory response of the IVD.Recently emerging transient receptor potential channels have been recognized as contributors to neurogenic inflammation in the degenerative IVDs.These findings suggest that neurogenic inflammation involves complex pathophysiological interactions between sensory nerves and multiple cell types in the degenerative IVDs.Clarifying the mechanism of neurogenic inflammation in IVD degeneration may provide in-depth understanding of the pathology of discogenic low back pain.

文摘Intervertebral disc degeneration is a leading cause of lower back pain and is characterized by pathological processes such as nucleus pulposus cell apoptosis,extracellular matrix imbalance,and annulus fibrosus rupture.These pathological changes result in disc height loss and functional decline,potentially leading to disc herniation.This comprehensive review aimed to address the current challenges in intervertebral disc degeneration treatment by evaluating the regenerative potential of stem cell-based therapies,with a particular focus on emerging technologies such as exosomes and gene vector systems.Through mechanisms such as differentiation,paracrine effects,and immunomodulation,stem cells facilitate extracellular matrix repair and reduce nucleus pulposus cell apoptosis.Despite recent advancements,clinical applications are hindered by challenges such as hypoxic disc environments and immune rejection.By analyzing recent preclinical and clinical findings,this review provided insights into optimizing stem cell therapy to overcome these obstacles and highlighted future directions in the field.
文摘Lumbar intervertebral disc degeneration is thought to be the main cause of low back pain,although the mechanisms by which it occurs and leads to pain remain unclear.In healthy adult discs,vessels and nerves are present only in the outer layer of the annulus fibrosus and in the bony endplate.Animal models,and histological and biomechanical studies have shown that annulus tear or endplate injury is the initiating factor for painful disc degeneration.Injury to the disc triggers a local inflammatory repair response that activates nociceptors and promotes the synthesis of neuropeptides such as substance P and calcitonin generelated peptide,by dorsal root ganglion neurons.These neuropeptides are transported to injured discs and act as pro-inflammatory molecules,promoting the production of an“inflammatory soup”by inducing vasodilatation and plasma extravasation as well as by promoting the release of chemical mediators from disc cells and infiltrating immune cells,causing neurogenic inflammation that leads to progressive disc degeneration and discogenic pain.

文摘Degenerative spine pathologies,including intervertebral disc(IVD)degeneration,present a significant healthcare challenge due to their association with chronic pain and disability.This study explores an innovative approach to IVD regeneration utilizing 3D bioprinting technology,specifically visible light-based digital light processing,to fabricate tissue scaffolds that closely mimic the native architecture of the IVD.Utilizing a hybrid bioink composed of gelatin methacrylate(GelMA)and poly(ethylene glycol)diacrylate(PEGDA)at a 10%concentration,we achieved enhanced printing fidelity and mechanical properties suitable for load-bearing applications such as the IVD.Preconditioning rat bone marrow-derived mesenchymal stem cell spheroids with chondrogenic media before incorporating them into the GelMA-PEGDA scaffold further promoted the regenerative capabilities of this system.Our findings demonstrate that this bioprinted scaffold not only supports cell viability and integration but also contributes to the restoration of disc height in a rat caudal disc model without inducing adverse inflammatory responses.The study underscores the potential of combining advanced bioprinting techniques and cell preconditioning strategies to develop effective treatments for IVD degeneration and other musculoskeletal disorders,highlighting the need for further research into the dynamic interplay between cellular migration and the hydrogel matrix.

文摘Backgroud:Intervertebral disc degeneration(IDD)is one of the common degenerative diseases.Due to ethical constraints,it is difficult to obtain sufficient research on humans,so the use of an animal model of IDD is very important to clarify the pathogenesis and treatment mechanism of the disease.Methods:In this study,thirty 2-month-old mice were selected for operation to establish a coccygeal IDD model.The distal tail portion of the tail(beyond the 17th coccygeal vertebra)and a small piece of skin above the 8th coccygeal vertebra were excised,and the two incisions were brought together after flexion,and secured with sutures.The heights and signal intensities of the intervertebral discs(IVDs)were assessed using microcomputed tomography(μCT)and magnetic resonance imaging(MRI)at 0,6,12 weeks postoperatively.The overall tissue morphology,cell distribution and density,and extracellular matrix of the IVDs were also assessed using Hematoxylin and Eosin(HE),Safranin O-Fast Green and immunohistochemical staining.Results:All mice in the experimental group survived after the operation,and there were no complications such as wound infection,tail necrosis and suture shedding.The experimental results demonstrated that the suturing method can successfully initiate IDD.Different severity levels of IDD can be induced by controlling the bending angle of the IVDs within the tail loop;however,for consistency,histologic and imaging results should be obtained at the same bending angle and looping period.Conclusions:This IDD model is an effective method for studying the etiology and treatment of degenerative IVD disease.

文摘Background:Intervertebral disc degeneration(IVDD)is a multifaceted condition characterized by heterogeneity,wherein the balance between catabolism and anabolism in the extracellular matrix of nucleus pulposus(NP)cells plays a central role.Presently,the available treatments primarily focus on relieving symptoms associated with IVDD without offering an effective cure targeting its underlying pathophysiological processes.D-mannose(referred to as mannose)has demonstrated anti-catabolic properties in various diseases.Nevertheless,its therapeutic potential in IVDD has yet to be explored.Methods:The study began with optimizing the mannose concentration for restoring NP cells.Transcriptomic analyses were employed to identify the mediators influenced by mannose,with the thioredoxin-interacting protein(TXNIP)gene showing the most significant differences.Subsequently,small interfering RNA(siRNA)technology was used to demonstrate that TXNIP is the key gene through which mannose exerts its effects.Techniques such as colocalization analysis,molecular docking,and overexpression assays further confirmed the direct regulatory relationship between mannose and TXNIP.To elucidate the mechanism of action of mannose,metabolomics techniques were employed to pinpoint glutamine as a core metabolite affected by mannose.Next,various methods,including integrated omics data and the Gene Expression Omnibus(GEO)database,were used to validate the one-way pathway through which TXNIP regulates glutamine.Finally,the therapeutic effect of mannose on IVDD was validated,elucidating the mechanistic role of TXNIP in glutamine metabolism in both intradiscal and orally treated rats.Results:In both in vivo and in vitro experiments,it was discovered that mannose has potent efficacy in alleviating IVDD by inhibiting catabolism.From a mechanistic standpoint,it was shown that mannose exerts its anti-catabolic effects by directly targeting the transcription factor max-like protein X-interacting protein(MondoA),resulting in the upregulation of TXNIP.This upregulation,in turn,inhibits glutamine metabolism,ultimately accomplishing its anticatabolic effects by suppressing the mitogen-activated protein kinase(MAPK)pathway.More importantly,in vivo experiments have further demonstrated that compared with intradiscal injections,oral administration of mannose at safe concentrations can achieve effective therapeutic outcomes.Conclusions:In summary,through integrated multiomics analysis,including both in vivo and in vitro experiments,this study demonstrated that mannose primarily exerts its anti-catabolic effects on IVDD through the TXNIP-glutamine axis.These findings provide strong evidence supporting the potential of the use of mannose in clinical applications for alleviating IVDD.Compared to existing clinically invasive or pain-relieving therapies for IVDD,the oral administration of mannose has characteristics that are more advantageous for clinical IVDD treatment.

文摘Intervertebral disc degeneration is a degenerative disease where inflammation and immune responses play significant roles.Macrophages,as key immune cells,critically regulate inflammation through polarization into different phenotypes.In recent years,the role of macrophages in inflammation-related degenerative diseases,such as intervertebral disc degeneration,has been increasingly recognized.Macrophages construct the inflammatory microenvironment of the intervertebral disc and are involved in regulating intervertebral disc cell activities,extracellular matrix metabolism,intervertebral disc vascularization,and innervation,profoundly influencing the progression of disc degeneration.To gain a deeper understanding of the inflammatory microenvironment of intervertebral disc degeneration,this review will summarize the role of macrophages in the pathological process of intervertebral disc degeneration,analyze the regulatory mechanisms involving macrophages,and review therapeutic strategies targeting macrophage modulation for the treatment of intervertebral disc degeneration.These insights will be valuable for the treatment and research directions of intervertebral disc degeneration.

文摘Objective To observe the influence of acupuncture on the post-operative rehabilitation in patients undergoing vertebral pulp extraction due to lumbar intervertebral disc protrusion (LIDP) so as to evaluate its efficacy in the treatment of lumbago induced by LIDP. Methods A total of 69 patients undergoing vertebral pulp extraction were randomized into acupuncture group ( n = 35) and control group ( n = 34). Patients of acupuncture group were treated with routine rehabilitation method and electroacupuncture (EA) stimulation on Zhìbiān (秩边 BL54) and Wěizhōng (委中 BL40), acupuncture on Shènshū ( 肾俞 BL23), Dàchángshū (大肠俞 BL25), BL54, BL40, Jiájǐ (夹脊 EX-B 2), Shàngliáo (上髎 BL31), etc., and cupping on BL40, with 15 days being a therapeutic course and for average 7. 36 courses. Patients of control group were treated with simple rehabilitation method. Functional recovery state was judged before and after surgery by using the standards of Japanese Orthopedic Association (JOA). Results The average recovery rates of 3 months, 6 months and one year after surgery were 49.93% ,90.31% and 95.08% separately in acupuncture group, and 26.24% ,63.42% and 71.36% successively in control group. The recovery rates of acupuncture group were significantly higher than those of control group at the same time-points (P〈0. 05). Conclusion Acupuncture has a definite effect on promoting post-operative functional recovery in LIDP patients undergoing vertebral pulp extraction and spinal fusion.
文摘Objective:To provide anatomical datum for intrusive operations of lumbar intervertebral foramen,especially that using acupuncture-knife as intrusive tool.Methods:To dissect 10 antisepsis cadavers and observe the exposed blood vessels,ligaments,nerves and their adjacent relations in L1/2~L5/S1intervertebral foramen.Results:Lumbar intervertebral foramen exit zones were almost sealed by nerves and blood vessels.There were two zones with relatively no blood vessel and nerve(triangular working zones)located in the midpoint of the distance between two adjacent roots of transverse processus,and clung to lamina of vertebral arch,and they were also found upon the margo superior of the root of transverse processus,but the ascending lumbar vein or(and)the rami anastomoticus between the remi inferior of intervertebral vein and lumbar veins were observed in 12%triangular working zones upon the margo superior of root of transverse processus.Conclusions:"Triangular working zone"was relatively avascular zone.Pay attention to the possibilty of presence of blood vessels on the entrance passage of intrusive operations on lumbar side rear.The needlepoint should be pierced at the midpoint of the distance between two adjacent roots of transverse processus and cling to the outer edge of lamina of vertebral arch when doing the foraminal lumbar puncture.As lumbar intervertebral foramina exit zone was almost sealed by nerves and blood vessels,blind incising and debonding with acupuncture-knife in this area was relatively much more dangerous.
文摘Objective To observe the clinical effects of body acupuncture and wrist-ankle acupuncture on prolapse of lumbar intervertebral disc, Methods One hundred and eighty cases of prolapse of lumbar intervertebral disc were randomly divided into body acupuncture and wrist-ankle acupuncture group (observation group) and simple body acupuncture group (control group), 90 cases in each one. In observation group, body acupuncture was applied on Ahshi points of lumbar region, lumbar Jiájǐ (夹脊EX-B 2), Dàchángshú(大肠俞 BL 25), etc. and wrist-ankle acupuncture was applied on lower No. 4, 5 and 6 regions. In control group, simple body acupuncture was applied on the same points as observation group. Results The lumbar vertebral function and pain scale were improved in either group in comparison before and after treatment (P〈0.05). Concerning pain improvement, the total effective rate was 95.6% in observation group, which was superior to that (86.7%) in control group (P〈0.05). Concerning the improvement of lumbar vertebral function, the total effective rate was 90.0% in observation group and 93.3% in control group, without significant difference between two groups (P〉0.05). Conclusion Combined therapy of body acupuncture and wrist-ankle acupuncture demonstrates apparent analgesia in prolapse of lumbar intervertebral disc.

文摘OBJECTIVE: A systematic review of the literature was conducted to evaluate the curative effect and safety of Duhuojisheng Tang on prolapse of the lumbar intervertebral disc. METHODS: The databases of PubMed, China Na- tional Knowledge Infrastructure (CNKI), Chinese Sci- entific Journals Database (VlP), Chinese Biomedical Literature Database (CBM) and Chinese Medical Ci- tation Index (CMCl) were searched up to January 30, 2012. Randomized controlled trials were select- ed to compare Duhuojisheng Tang with one ormore of the following treatments: traction, acu- puncture, massage, cupping and Western medical treatment. The quality-evaluating standard and the software RevMan 5.1 in Cochrane coordinative net were used to analyze the data. The effective index- es of the results were clinical curative rate, effective- ness of alleviating clinical symptoms and adverse reaction. RESULTS: Thirty-one randomized controlled trials of low quality, involving 3915 patients were system- atically evaluated. Statistical analyses showed that good curative effect was achieved in both the group using Duhuojisheng Tang alone and with combined therapies. CONCLUSION: Using Duhuojisheng Tang alone or combined with other therapies can effectively im- prove pain, leg-raising height and other clinical symptoms of patients with prolapse of lumbar in- tervertebral disc. Due to low methodological quali- ty of the articles, no exact recommendations can be made.

文摘Objective:The age-related change is important part of degenerative disc disease. However,no appropriate animal model or objective evaluation index is available. This study aimed to investigate the features of intervertebral disc degeneration in aging process of rats. Methods:22-month-old Sprague-Dawley(SD) rats were used as spontaneously occurring intervertebral disc degeneration models and 6-month-old rats as young controls. Expression of collagen types II and X was measured by immunohistochemistry. Degenerations of intervertebral discs were scored according to Miyamoto's method. Numbers and areas of afferent vascular buds were measured. The thicknesses of non-calcified and calcified layers were measured and statistically analyzed. Results:There were less collagen type II expression and more collagen type X expression in the calcified layer of the cartilage endplates and nucleus pulposus in the rats of the aged group than in the young control. There were fewer and smaller afferent vascular buds in the rats of the aged group than in the young control group. The ratio of the non-calcified to the calcified layers in the rats of the aged group significantly decreased,compared with that of the young control group(P<0.01) . Conclusion:Rats can spontaneously establish intervertebral disc age-related degeneration. The expression of collagen types II and X,numbers and areas of afferent vascular buds,the ratio of the non-calcified to the calcified layers,and water and glycosaminoglycan contents in the nucleus pulposus are sensitive indexes of intervertebral disc degeneration.
