| 1 | Pathophysiology, diagnosis, and treatment of discogenic low back pain显示文摘Discogenic low back pain is a serious medical and social problem, and accounts for 26%-42% of the patients with chronic low back pain. Recent studies found that the pathologic features of discs obtained from the patients with discogenic low back pain were the formation of the zones of vascularized granulation tissue, with extensive innervation in fissures extending from the outer part of the annulus into the nucleus pulposus. Studies suggested that the degeneration of the painful disc might originate from the injury and subsequent repair of annulus fibrosus. Growth factors such as basic fibroblast growth factor, transforming growth factor β1, and connective tissue growth factor, macrophages and mast cells might play a key role in the repair of the injured annulus fibrosus and subsequent disc degeneration. Although there exist controversies about the role of discography as a diagnostic test, provocation discography still is the only available means by which to identify a painful disc. A recent study has classified discogenic low back pain into two types that were annular disruption-induced low back pain and internal endplate disruption-induced low back pain, which have been fully supported by clinical and theoretical bases. Current treatment options for discogenic back pain range from medicinal anti-inflammation strategy to invasive procedures including spine fusion and recently spinal arthroplasty. However, these treatments are limited to relieving symptoms, with no attempt to restore the disc's structure. Recently, there has been a growing interest in developing strategies that aim to repair or regenerate the degenerated disc biologically. | Bao-Gan Peng | 2013 | World Journal of Orthopedics2013，4，2： | 40 |
| 2 | Painful intervertebral disc degeneration and inflammation:from laboratory evidence to clinical interventions显示文摘Low back pain(LBP),as a leading cause of disability,is a common musculoskeletal disorder that results in major social and economic burdens.Recent research has identified inflammation and related signaling pathways as important factors in the onset and progression of disc degeneration,a significant contributor to LBP.Inflammatory mediators also play an indispensable role in discogenic LBP.The suppression of LBP is a primary goal of clinical practice but has not received enough attention in disc research studies.Here,an overview of the advances in inflammation-related pain in disc degeneration is provided,with a discussion on the role of inflammation in IVD degeneration and pain induction.Puncture models,mechanical models,and spontaneous models as the main animal models to study painful disc degeneration are discussed,and the underlying signaling pathways are summarized.Furthermore,potential drug candidates,either under laboratory investigation or undergoing clinical trials,to suppress discogenic LBP by eliminating inflammation are explored.We hope to attract more research interest to address inflammation and pain in IDD and contribute to promoting more translational research. | Feng-Juan Lyu Haowen Cui Hehai Pan Kenneth MC Cheung Xu Cao James C.Iatridis Zhaomin Zheng | 2021 | Bone Research2021，9，1： | 24 |
| 3 | Subchondral bone microenvironment in osteoarthritis and pain显示文摘Osteoarthritis comprises several joint disorders characterized by articular cartilage degeneration and persistent pain,causing disability and economic burden.The incidence of osteoarthritis is rapidly increasing worldwide due to aging and obesity trends.Basic and clinical research on osteoarthritis has been carried out for decades,but many questions remain unanswered.The exact role of subchondral bone during the initiation and progression osteoarthritis remains unclear.Accumulating evidence shows that subchondral bone lesions,including bone marrow edema and angiogenesis,develop earlier than cartilage degeneration.Clinical interventions targeting subchondral bone have shown therapeutic potential,while others targeting cartilage have yielded disappointing results.Abnormal subchondral bone remodeling,angiogenesis and sensory nerve innervation contribute directly or indirectly to cartilage destruction and pain.This review is about bone-cartilage crosstalk,the subchondral microenvironment and the critical role of both in osteoarthritis progression.It also provides an update on the pathogenesis of and interventions for osteoarthritis and future research targeting subchondral bone. | Yan Hu Xiao Chen Sicheng Wang Yingying Jing Jiacan Su | 2021 | Bone Research2021，9，3： | 24 |
| 4 | Melatonin alleviates intervertebral disc degeneration by disrupting the IL-1β/NF-κB-NLRP3 inflammasome positive feedback loop显示文摘The inflammatory response is induced by the overexpression of inflammatory cytokines, mainly interleukin(IL)-1β, and is one of the main causes of intervertebral disc degeneration(IVDD). NLR pyrin domain containing 3(NLRP3) inflammasome activation is an important source of IL-1β. As an anti-inflammatory neuroendocrine hormone, melatonin plays various roles in different pathophysiological conditions. However, its roles in IVDD are still not well understood and require more examination. First, we demonstrated that melatonin delayed the progression of IVDD and relieved IVDD-related low back pain in a rat needle puncture IVDD model;moreover, NLRP3 inflammasome activation(NLRP3, p20, and IL-1β levels) was significantly upregulated in severely degenerated human discs and a rat IVDD model. Subsequently, an IL-1β/NF-κB-NLRP3 inflammasome activation positive feedback loop was found in nucleus pulposus(NP) cells that were treated with IL-1β. In these cells, expression of NLRP3 and p20 was significantly increased, NF-κB signaling was involved in this regulation, and mitochondrial reactive oxygen species(mt ROS)production increased. Furthermore, we found that melatonin disrupted the IL-1β/NF-κB-NLRP3 inflammasome activation positive feedback loop in vitro and in vivo. Melatonin treatment decreased NLRP3, p20, and IL-1β levels by inhibiting NF-κB signaling and downregulating mt ROS production. Finally, we showed that melatonin mediated the disruption of the positive feedback loop of IL-1β in vivo. In this study, we showed for the first time that IL-1β promotes its own expression by upregulating NLRP3 inflammasome activation. Furthermore, melatonin disrupts the IL-1β positive feedback loop and may be a potential therapeutic agent for IVDD. | Fan Chen Guowei Jiang Hui Liu Zemin Li Yuxin Pei Hua Wang Hehai Pan Haowen Cui Jun Long Jianru Wang Zhaomin Zheng | 2020 | Bone Research2020，8，2： | 18 |
| 5 | NUTRITIONAL LIPID LIVER DISEASE OF GRASS CARP CTENOPHARYNGODON IDULLUS(C.et V.)显示文摘The inadequate nutrient content of pellet feeds widely used in recent years in China for grass carp forming led to lipid liver degeneration in the fish. The present studies show that the pathological features of lipid liver disease are anaemia and hepatic ceroidosis. Other clinical features are: the ratio of liver to body weight exceeds 3% and lipid content exceeds 5%. Extreme infiltration of hepaiocytes by lipid results in the following deteriorative effects: swelling of the liver cells, increase of lipid droplets in the cytoplasm and dislocation of the nucleus, loss of cytoplasm staining affinity, and increased activities of GOT and GPT in serum. Lipid liver degeneration of grass carp can be divided into three stages: 1) deposition of liver lipid; 2) lipid infiltration of hepatic parenchyma; 3) atrophy of liver nucleus. The causes of lipid liver degeneration are complicated, but the main cause is assumed to be an imbalance of nutrients in daily feed and the lack of some lipotropic substances. | 林鼎 毛永庆 蔡发盛 | 1990 | Chinese Journal of Oceanology and Limnology1990，8，4： | 16 |

| 7 | Lycium barbarum polysaccharides protected human retinal pigment epithelial cells against oxidative stressinduced apoptosis显示文摘AIM: To investigate the protective effect and its mechanism of lycium barbarum polysaccharides(LBP)against oxidative stress-induced apoptosis in human retinal pigment epithelial cells.METHODS: ARPE-19 cells, a human retinal pigment epithelial cell lines, were exposed to different concentrations of H2O2 for 24h, then cell viability was measured by Cell Counting Kit-8(CCK-8) assay to get the properly concentration of H2O2 which can induce half apoptosis of APRE-19. With different concentrations of LBP pretreatment, the ARPE-19 cells were then exposed to appropriate concentration of H2O2, cell apoptosis was detected by flow cytometric analysis. Expression levels of Bcl-2 and Bax were measured by real time quantitative polymerase chain reaction(RT-PCR) technique.RSULTS: LBP significantly reduced the H2O2-induced ARPE-19 cells' apoptosis. LBP inhibited the H2O2-induced down-regulation of Bcl-2 and up-regulation of Bax.CONCLUSION: LBP could protect ARPE-19 cells from H2O2-induced apoptosis. The Bcl-2 family had relationship with the protective effects of LBP. | Lian Liu Wei Lao Qing-Shan Ji Zhi-Hao Yang Guo-Cheng Yu Jing-Xiang Zhong | 2015 | International Journal of Ophthalmology(English edition)2015，8，1： | 15 |
| 8 | Genetically confirmed Wilson disease in a 9-month old boy with elevations of aminotransferases显示文摘Wilson disease (WD) is an autosomal recessive disorder of copper transport caused by alteration of the adenosine triphosphatase 7B gene. It is rare to diagnose WD below the age of three years. Molecular genetic testing is one of the most important diagnostic methods and may confirm the diagnosis in equivocal cases. We report a case of a 9-mo old boy with WD who presented as chronic hepatitis. Genetic analysis showed compound heterozygotes of p.G1186S and c.4006delA. | Joo Whee Kim Jong Hyun Kim Jeong Kee Seo Jae Sung Ko Ju Young Chang Hye Ran Yang Kyung Hoon Kang | 2013 | World Journal of Hepatology2013，5，3： | 11 |
| 9 | Why microglia kill neurons after neural disorders? The friendly fire hypothesis显示文摘Neuroinflammation plays a fundamental role on the pathophysiology of acute and chronic neural disorders.Microglia activation is a major event following central nervous system inflammation displaying different phenotypes with beneficial and detrimental actions(a Janus face).The reason for this apparent duality is unknown.We have previously shown that following experimental middle cerebral artery occlusion in the rat brain,microglia seem to support and impair adult neurogenesis in the same ischemic striatum.Based on these results,we raised the hypothesis that in the same pathologic environment,gradients of different ligands distributed over different anatomical niches might contribute to both detrimental and beneficial microglial phenotypes.These ligands(“danger signals”)are released by dying cells and bind to microglial receptors in their membranes.Activation of different microglial receptors induces downstream biochemical pathways culminating in a spectrum of microglial phenotypes like M1 and M2 and others.In this paper,we first review the immune functions of microglia and the role of toll-like receptors on the fight against infections.We then briefly revise the dual role of microglia after neural disorders.We then propose a novel hypothesis to explain the Janus face of microglia during the pathophysiology of central nervous system diseases:the“friendly fire hypothesis”.According to this idea“danger signals”or danger associated molecular patterns released by stressed,damaged and/or dying cells during stroke,trauma and other diseases might activate microglial pattern-recognition receptors(i.e.,toll like receptors)or other unidentified receptors normally activated by pathogens.This could activate the same genetic and biochemical machinery used by microglia to fight against pathogens even in the absence of infection.According to this notion,microglia may cause bystander neuronal damage with a kind of blind“friendly fire”,fighting against a non-existing infection during non-infectious disorders,like stroke and trauma.The“friendly fire hypothesis”is a novel proposal to explain why microglia may be detrimental and beneficial after acute and chronic neural disorders and may direct future investigations for developing of neuroprotective agents. | Walace Gomes-Leal | 2019 | Neural Regeneration Research2019，14，9： | 9 |

| 11 | Stabilization of heterochromatin by CLOCK promotes stem cell rejuvenation and cartilage regeneration显示文摘Accumulating evidence indicates an association between the circadian clock and the aging process.However,it remains elusive whether the deregulation of circadian clock proteins underlies stem cell aging and whether they are targetable for the alleviation of aging-associated syndromes.Here,we identified a transcription factor-independent role of CLOCK,a core component of the molecular circadian clock machinery,in counteracting human mesenchymal stem cell(hMSC)decay.CLOCK expression was decreased during hMSC aging.In addition,CLOCK deficiency accelerated hMSC senescence,whereas the overexpression of CLOCK,even as a transcriptionally inactive form,rejuvenated physiologically and pathologically aged hMSCs.Mechanistic studies revealed that CLOCK formed complexes with nuclear lamina proteins and KAP1,thus maintaining heterochromatin architecture and stabilizing repetitive genomic sequences.Finally,gene therapy with lentiviral vectors encoding CLOCK promoted cartilage regeneration and attenuated age-related articular degeneration in mice.These findings demonstrate a noncanonical role of CLOCK in stabilizing heterochromatin,promoting tissue regeneration,and mitigating aging-associated chronic diseases. | Chuqian Liang Zunpeng Liu Moshi Song Wei Li Zeming Wu Zehua Wang Qiaoran Wang Si Wang Kaowen Yan Liang Sun Tomoaki Hishida Yanning Cai Juan Carlos lzpisua Belmonte Pedro Guillen Piu Chan Qi Zhou Weiqi Zhang Jing Qu Guang-Hui Liu | 2021 | Cell Research2021，31，2： | 8 |
| 12 | Bevacizumab vs ranibizumab for neovascular age-related macular degeneration in Chinese patients显示文摘AIM: To compare the clinical efficacy of intravitreal injections of bevacizumab and ranibizumab for treating Chinese patients with neovascular age-related macular degeneration (AMD).METHODS: Among 60 Chinese patients with exudative AMD (60 eyes), 28 received intravitreal bevacizumab injections (1.25mg) and 32 received intravitreal ranibizumab injections (0.5mg), once a month for 3 months and were followed for a total of 6 months. Monthly optical coherence tomography (OCT) was used to determine whether the patients received additional treatments during the follow-up. We compared the baseline and 6 -month follow-up values of mean best-corrected visual acuity (BCVA) and central retinal thickness (CRT) in both groups of patients. We also compared the occurrence of adverse events.RESULTS: At the 6-month follow-up, the mean BCVA (logMAR) of the bevacizumab and ranibizumab treatment groups improved from the baseline measurements of 0.72 ±0.23 and 0.73 ±0.22 to 0.47 ±0.14 and 0.45 ±0.20, respectively (P <0.05 for both groups). However, the change was not significantly different between the two groups. As evaluated by OCT, CRT decreased from 366.71 ±34.72μm and 352 ±36.9μm at baseline to 250.86 ± 41.51μm and 243.22 ±41.38μm in the bevacizumab and ranibizumab groups, respectively (P <0.05 for both groups). However, the change was not significantly different between the two groups. There were no severe local adverse reactions or systemic adverse events.CONCLUSION:Intravitreal bevacizumab and ranibizumab have equivalent effects on BCVA and CRT and appeare safe over the short-term. | Jun Li Han Zhang Peng Sun Feng Gu Zhe-Li Liu | 2013 | International Journal of Ophthalmology(English edition)2013，6，2： | 8 |
| 13 | Insights of stem cell-based endogenous repair of intervertebral disc degeneration显示文摘Low back pain has become more prevalent in recent years,causing enormous economic burden for society and government.Common therapies used in clinics including conservative treatment and surgery can only relieve pain.Subsequent cell-based treatment such as mesenchymal stem cell transplantation poses problems such as short duration of therapeutic effect and tumorigenesis.Recently,the discovery and identification of stem cell niche and stem/progenitor cells in intervertebral disc bring increased attention to endogenous repair strategy.Therefore,we review the studies involving endogenous repair strategy and present the characteristics and current status of this treatment.Meanwhile,we also discuss the strategy and perspective of endogenous repair strategy in future. | Yang Liu Yan Li Li-Ping Nan Feng Wang Shi-Feng Zhou Xin-Min Feng Hao Liu Liang Zhang | 2020 | World Journal of Stem Cells2020，12，4： | 7 |
| 14 | Stem cells sources for intervertebral disc regeneration显示文摘Intervertebral disc regeneration field is rapidly growing since disc disorders represent a major health problem in industrialized countries with very few possible treatments.Indeed, current available therapies are symptomatic, and surgical procedures consist in disc removal and spinal fusion, which is not immune to regardable concerns about possible comorbidities, cost-effectiveness, secondary risks and long-lasting outcomes. This review paper aims to share recent advances in stem cell therapy for the treatment of intervertebral disc degeneration. In literature the potential use of different adult stem cells for intervertebral disc regeneration has already been reported. Bone marrow mesenchymal stromal/stem cells, adipose tissue derived stem cells, synovial stem cells, muscle-derived stem cells, olfactory neural stem cells, induced pluripotent stem cells, hematopoietic stem cells, disc stem cells, and embryonic stem cells have been studied for this purpose either in vitro or in vivo. Moreover, several engineered carriers(e.g., hydrogels), characterized by full biocompatibility and prompt biodegradation, have been designed and combined with different stem cell types in order to optimize the local and controlled delivery of cellular substrates in situ. The paper overviews the literature discussing the current status of our knowledge of the different stem cells types used as a cell-based therapy for disc regeneration. | Gianluca Vadalà Fabrizio Russo Luca Ambrosio Mattia Loppini Vincenzo Denaro | 2016 | World Journal of Stem Cells2016，8，5： | 7 |
| 15 | Predictors of visual outcome in eyes with choroidal neovascularization secondary to age related macular degeneration treated with intravitreal bevacizumab monotherapy显示文摘AIM:To evaluate the predictors of visual improvement in eyes with naive choroidal neovascularization secondary to age-related macular degeneration (CNV -AMD) treated with intravitreal bevacizumab (IVB) monotherapy. METHODS:Fifty eyes with naive CNV-AMD with pretreatment best-corrected visual acuity (BCVA) better than 20/200 and treated with IVB monotherapy were evaluated. Several variables including age, sex, pre-treatment BCVA, CNV type and lesion size on fluorescein angiogram as well as SD-OCT parameters including pre-treatment central macular thickness (CMT), inner-segment/outer-segment (IS/OS) junction integrity, and external limiting membrane (ELM) integrity were analyzed to predict visual outcome.RESULTS:On univariate regression, pretreatment ELM damage was associated with less visual improvement after treatment (P =0.0145). However, ELM damage predicted only 10% of the visual outcome. On multivariate regression, pretreatment BCVA, IS/OS junction, and ELM integrity on SD-OCT were the significant predictors for the treatment effect and together predicted 37% of visual improvement. CONCLUSION:Pretreatment BCVA, ELM and IS/OS junction integrity on SD-OCT are of significant value inpredicting the visual improvement in naive wet AMD patients treated with IVB monotherapy. | Jay Chhablani Jae SukKim William R Freeman Igor Kozak Hai-Yan Wang Lingyun Cheng | 2013 | International Journal of Ophthalmology(English edition)2013，6，1： | 6 |

| 17 | Diabetic retinopathy:neurovascular disease requiring neuroprotective and regenerative therapies显示文摘It is well known that diabetic retinopathy is a neurovascular disease that is accompanied by dysfunction of neurovascular units com posed of neurons,glial cells,and vascular cells(Antonetti et al.,2012;Figure1).Many studies have reported that the neuronal abnormalities,such as neuronal cell death,frequently precedes vascularabnormalities including neovascularization(Sohn et al.,2016).Neuronal cell death and axonal degeneration are irreversible changes under normal physiological conditions,and they are directly linked to the vision decrease. | Toshiyuki Oshitari | 2022 | Neural Regeneration Research2022，17，4： | 6 |
| 18 | Stromal cell-derived factor-1α promotes recruitment and differentiation of nucleus pulposus-derived stem cells显示文摘BACKGROUND Intervertebral disc(IVD) degeneration is a condition characterized by a reduction in the water and extracellular matrix content of the nucleus pulposus(NP) and is considered as one of the dominating contributing factors to low back pain. Recent evidence suggests that stromal cell-derived factor 1α(SDF-1α) and its receptor CX-C chemokine receptor type 4(CXCR4) direct the migration of stem cells associated with injury repair in different musculoskeletal tissues.AIM To investigate the effects of SDF-1α on recruitment and chondrogenic differentiation of nucleus pulposus-derived stem cells(NPSCs).METHODS We performed real-time RT-PCR and enzyme-linked immunosorbent assay to examine the expression of SDF-1α in nucleus pulposus cells after treatment with pro-inflammatory cytokines in vitro. An animal model of IVD degeneration was established using annular fibrosus puncture in rat coccygeal discs. Tissue samples were collected from normal control and degeneration groups.Differences in the expression of SDF-1α between the normal and degenerative IVDs were analyzed by immunohistochemistry. The migration capacity of NPSCs induced by SDF-1α was evaluated using wound healing and transwell migration assays. To determine the effect of SDF-1α on chondrogenic differentiation of NPSCs, we conducted cell micromass culture and examined the expression levels of Sox-9, aggrecan, and collagen II. Moreover, the roles of SDF-1/CXCR4 axis in the migration and chondrogenesis differentiation of NPSCs were analyzed by immunofluorescence, immunoblotting, and real-time RT-PCR.RESULTS SDF-1α was significantly upregulated in the native IVD cells cultured in vitro with pro-inflammatory cytokines, such as interleukin-1β and tumor necrosis factor-α, mimicking the degenerative settings. Immunohistochemical staining showed that the level of SDF-1α was also significantly higher in the degenerative group than in the normal group. SDF-1α enhanced the migration capacity of NPSCs in a dose-dependent manner. In addition, SDF-1α induced chondrogenic differentiation of NPSCs, as evidenced by the increased expression of chondrogenic markers using histological and immunoblotting analyses. Realtime RT-PCR, immunoblotting, and immunofluorescence showed that SDF-1αnot only increased CXCR4 expression but also stimulated translocation of CXCR4 from the cytoplasm to membrane, accompanied by cytoskeletal rearrangement.Furthermore, blocking CXCR4 with AMD3100 effectively suppressed the SDF-1α-induced migration and differentiation capacities of NPSCs.CONCLUSION These findings demonstrate that SDF-1α has the potential to enhance recruitment and chondrogenic differentiation of NPSCs via SDF-1/CXCR4 chemotaxis signals that contribute to IVD regeneration. | Jin-Wei Ying Tian-Yong Wen Shi-Shen Pei Ling-Hao Su Di-Ke Ruan | 2019 | World Journal of Stem Cells2019，11，3： | 6 |
| 19 | A macroscopic multi-mechanism based constitutive model for the thermo-mechanical cyclic degeneration of shape memory effect of NiTi shape memory alloy显示文摘A macroscopic based multi-mechanism constitutive model is constructed in the framework of irreversible thermodynamics to describe the degeneration of shape memory effect occurring in the thermo-mechanical cyclic deformation of NiTi shape memory alloys(SMAs). Three phases,austenite A, twinned martensite Mtand detwinned martensite M^d, as well as the phase transitions occurring between each pair of phases( A → M^t, M^t→ A, A → M^d,M^d→ A, and M^t→ M^d) are considered in the proposed model. Meanwhile, two kinds of inelastic deformation mechanisms, martensite transformation-induced plasticity and reorientation-induced plasticity, are used to explain the degeneration of shape memory effects of NiTi SMAs. The evolution equations of internal variables are proposed by attributing the degeneration of shape memory effect to the interaction between the three phases(A, M^t, and M^d) and plastic deformation. Finally, the capability of the proposed model is verified by comparing the predictions with the experimental results of NiTi SMAs. It is shown that the degeneration of shape memory effect and its dependence on the loading level can be reasonably described by the proposed model. | Chao Yu Guozheng Kang Qianhua Kan | 2017 | Acta Mechanica Sinica2017，33，3： | 6 |
