Abstract
OBJECTIVE There is no study comparing knee and spine osteoarthritis. The purpose of the study is to examine the effects of pain and disability on quality of life (QoL) and the factors affecting QoL in patients with knee osteoarthritis and spondylosis. METHODS This cross-sectional study included 114 patients with spondylosis and 126 patients with knee osteoarthritis. Demographic data were recorded. The visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Roland Morris Questionnaire (RMQ), and the Short Form Health Questionnaire (SF-36) were filled out. RESULTS Statistically, patients with spondylosis and knee osteoarthritis did not differ significantly in terms of gender, age, body mass index, number of concomitant conditions, marital status, years of schooling, pain scores, or SF-36 characteristics. SF-36 physical function, vitality, and mental health assessments were lower in women than men, while VAS scores were higher. There was no correlation between marital status, educational level, and QoL subscales. WOMAC and RMQ scores were negatively correlated with the SF-36 subscales. RMS scores were not related to mental health. CONCLUSIONS Spondylosis and knee osteoarthritis affect all subscales of QoL in the same way. The management of patients with spondylosis and knee osteoarthritis should focus on pain and functionality to improve QoL.

Quality of Life in Patients with Chronic Low Back Pain and Differences by Sex: A Longitudinal Study. J Pers Med 2024; 14:496. [PMID: 38793078 PMCID: PMC11121820 DOI: 10.3390/jpm14050496] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2024] [Revised: 05/04/2024] [Accepted: 05/06/2024] [Indexed: 05/26/2024] Open
Abstract
BACKGROUND The experience of chronic low back pain has a significant impact on the quality of life of affected people, resulting in difficulties in performing basic activities of daily living. AIM To study the perceived quality of life of people affected by chronic low back pain and the associated factors by sex. METHODS A prospective, longitudinal and observational design was used. RESULTS A total of 129 people (58.1% women) with chronic low back pain were studied. The mean pain intensity scores were of moderate severity (6.42 points), with a modest improvement at follow-up (6.17 points). Epidural nerve blocks were the most effective therapeutic intervention in reducing the intensity of pain. Participants described a negative perception of their health with regard to quality of life, with low scores for the two constructs both at baseline (health index, 0.444; perception of health, 38.76 points) and at follow-up (health index, 0.447; perception of health, 40.43 points). Participants had severe functional limitation scores (50.79 points). The results were significantly better among men. There was an inverse relationship between the average pain intensity (β = -0.304; p < 0.001), functional limitation (β = -0.466; p < 0.001) and mental health (β = -0.565; p < 0.001) and quality of life. CONCLUSIONS The chronification of low back pain complicates people's biopsychosocial adaptation to life. There is a longitudinal inverse association between pain and functional limitation and health-related quality of life.

[PMID: 38665996 PMCID: PMC11043534 DOI: 10.3389/fneur.2024.1368988] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Accepted: 03/13/2024] [Indexed: 04/28/2024] Open
Abstract
Objective Acupuncture, acknowledged as a potent non-pharmacological therapy, is frequently employed to alleviate pain. Despite its widespread use, there has been a lack of overarching bibliometric analysis of clinical research on acupuncture analgesia. We aimed to summarize current patterns, hotspots, and development trends in this field through bibliometric analysis. Methods This study evaluates academic publications retrieved from the Web of Science database (2010.01-2023.09) concerning acupuncture analgesia in clinical settings. All primary and secondary studies on humans were included. To track global developmental trends, we employed several software for analyzing annual publication volumes, countries/regions, institutions, authors, cited authors, journals, cited journals, references, and keywords and to draw collaborative networks and reference co-citation network maps. Results The final search encompassed 7,190 relevant studies, including 1,263 randomized controlled trials (RCTs) and 1,293 systematic reviews and meta-analyses. The results indicated a gradual increase in the number of annual publications on acupuncture analgesia in clinical practice. Among countries and institutions, China (2,139) and Chengdu University of Traditional Chinese Medicine (258) ranked first. Liang FR (89 articles) was the most prolific author, while MacPherson H (604) was the most cited author. MEDICINE (455) was the most productive journal, and Pain (2,473/0.20) ranked first in both the frequency and centrality of cited journals. Notably, the most frequently cited reference was a systematic review of individual patient data on acupuncture carried out for chronic pain that was published by Vickers Andrew J in 2012 (156). Burst analysis identified frontier research areas for 2010-2020, encompassing network meta-analysis, case reports, dry needling, lumbar disc herniation, cancer, post-herpetic neuralgia, insomnia, and bibliometric analysis. Conclusion This study outlines current trends and potential future research hotspots in clinical acupuncture analgesia over the past decade. Findings emphasize the necessity for enhanced international collaboration to improve research output and translation.

Abstract
Low-back pain is a common occupational hazard for industrial workers. Several studies show the advantages of using rigid and soft back-support passive exoskeletons and exosuits (exos) to reduce the low-back loading and risk of injury. However, benefits of using these exos have been shown to be task-specific. Therefore, in this study, we developed a benchmarking approach to assess exos for an industrial workplace at Hankamp Gears B.V. We assessed two rigid (Laevo Flex, Paexo back) and two soft (Auxivo Liftsuit 1.0, and Darwing Hakobelude) exos for tasks resembling the workplace. We measured the assistive moment provided by each exo and their respective influence on muscle activity as well as the user's perception of comfort and exertion. Ten participants performed four lifting tasks (Static hold, Asymmetric, Squat, and Stoop), while their electromyography and subjective measures were collected. The two rigid exos provided the largest assistance during the Dynamic tasks. Reductions in erector spinae activity were seen to be task-specific, with larger reductions for the two rigid exos. Overall, Laevo Flex offered a good balance between assistive moments, reductions in muscle activity, as well as user comfort and reductions in perceived exertion. Thus, we recommend benchmarking exos for intended use in the industrial workplace. This will hopefully result in a better adoption of the back-support exoskeletons in the workplace and help reduce low-back pain.

Abstract
INTRODUCTION Low back pain (LBP) is a musculoskeletal condition that affects many individuals. While physiotherapy and acupuncture are frequently used treatments, determining their specific contributions when used alongside integrated yoga and naturopathy (IYN) therapy for relieving chronic LBP symptoms and enhancing quality of life is important. METHODOLOGY In the present prospective randomized comparative trial, a total of 60 participants were divided into the following two groups: physiotherapy with IYN and acupuncture with IYN. The treatment duration was 10 days, and assessments were conducted both before (baseline) and after the intervention. Various assessment tools, such as the visual analog scale (VAS), Oswestry Disability Index (ODI), fingertip-to-floor test (FTF), State-Trait Anxiety Inventory (STAI), and Short Form 36 (SF-36), were utilized. The statistical analysis was performed using SPSS version 21.0 (Armonk, NY: IBM Corp). RESULTS The results revealed significant differences in VAS score, ODI, FTF score, STAI score, and SF-36 score between the physiotherapy and acupuncture groups (p<0.001). A t-test for the equality of means and a Mann-Whitney U test were used to compare the two groups; these tests revealed a significant difference in disability levels, range of motion, and state of anxiety. The acupuncture group showed a significant difference in the ODI (15.9 {12.6, 19.3}; p <0.001) and state anxiety (23.0 {20.0, 26.0}; p<0.001) compared to the physiotherapy ODI (22.4 {18.5, 26.4}) and state anxiety (27.5 {25.0, 30.0}). The physiotherapy group showed a significant difference in range of motion (7.7 {5.7, 9.7}; p<0.001) compared to the acupuncture group (11.6 {9.8, 13.5}). CONCLUSION The present study findings revealed that both physiotherapy and acupuncture, as interventions along with integrated yoga and naturopathy may be considered an effective treatment strategy for chronic LBP.

Abstract
The prevalence of intervertebral disc degeneration in the lumbar region resulting in low back pain is high. One of the treatment options is neurosurgery. Previous studies and systematic reviews demonstrate the need to identify factors that affect the health-related quality of life of patients undergoing surgery. This study aimed to analyze the sociodemographic and clinical factors that affect the quality of life of patients undergoing lumbar disc surgery. A group of 128 patients was assessed for eligibility and qualified by radiological examinations for lumbar disc surgery by a neurosurgeon in the outpatient clinic. Finally, 110 patients were studied and evaluated 24 h and 3 months after surgery. Health-related quality of life (36-Item Short Form Survey, SF-36), disability level (Oswestry Disability Index, ODI), and pain intensity (Visual Analogue Scale, VAS) were assessed. The mean pain intensity before surgery was 7.8 ± 2.3 pts and decreased significantly 24 h after surgery, with a mean score of 3.8 ± 2.4 pts (p = 0.0000). After three months, the increase in pain intensity was at 4.8 ± 2.4 pts, but the score was still significantly better than before surgery (p = 0.0024). The mean ODI score before surgery was 29.3 ± 8.4 pts (slight disability), and three months after surgery, there was an insignificant increase to a mean value of 31.5 ± 10.4 pts (p = 0.0834). There was a statistically significant increase in quality-of-life scores at three months after surgery in the following domains: physical functioning (8.7%; p = 0.0176), bodily pain (26.2%; p = 0.0000), vitality (5.8%; p = 0.0132) and mental health (6.2%; p = 0.0163), and a decrease in role limitations due to physical problems (3.8; p = 0.0013) and general health perception (6.7%; p = 0.0112). In conclusion, the surgical procedure plays an important role in improving the quality of life of patients operated on for intervertebral disc degeneration. It was effective in reducing the pain level, especially 24 h after surgery; however, surgery did not affect the disability level.

Abstract
Low back pain (LBP) is the leading cause of disability worldwide. Most LBP is non-specific or idiopathic, which is defined as symptoms of unknown origin without a clear specific cause or pathology. Current guidelines for clinical evaluation are based on ruling out underlying serious medical conditions, but not on addressing underlying potential contributors to pain. Although efforts have been made to identify subgroups within this population based on response to treatment, a comprehensive framework to guide assessment is still lacking. In this paper, we propose a model for a personalized mechanism-based assessment based on the available evidence that seeks to identify the underlying pathologies that may initiate and perpetuate central sensitization associated with chronic non-specific low back pain (nsLBP). We propose that central sensitization can have downstream effects on the "myofascial unit", defined as an integrated anatomical and functional structure that includes muscle fibers, fascia (including endomysium, perimysium and epimysium) and its associated innervations (free nerve endings, muscle spindles), lymphatics, and blood vessels. The tissue-level abnormalities can be perpetuated through a vicious cycle of neurogenic inflammation, impaired fascial gliding, and interstitial inflammatory stasis that manifest as the clinical findings for nsLBP. We postulate that our proposed model offers biological plausibility for the complex spectrum of clinical findings, including tissue-level abnormalities, biomechanical dysfunction and postural asymmetry, ecological and psychosocial factors, associated with nsLBP. The model suggests a multi-domain evaluation that is personalized, feasible and helps rule out specific causes for back pain guiding clinically relevant management. It may also provide a roadmap for future research to elucidate mechanisms underlying this ubiquitous and complex problem.

Abstract
Introduction Low back pain (LBP) knowledge questionnaire (LKQ) was developed by a Brazilian research group in 2009. It has been cross-culturally adapted to many languages with good reliability and validity. This work aimed to translate and validate the LKQ into a simplified Chinese version and to evaluate the self-efficacy in LBP among Chinese participants from China and Hungary. Methods A total of 431 people participated in this research, which lasted from September 2021 to June 2022 and was conducted on the Credamo online platform. The simplified Chinese LKQ (sC-LKQ) was generated through translation and cross-cultural adaptation guidelines. The participants were selected to fill out demographic questions, the sC-LKQ, and the Roland-Morris Disability Questionnaire (RMDQ). The reliability and validity of the data were evaluated using SPSS 28.0. Results The sC-LKQ showed good internal consistency (Cronbach's alpha was 0.79), and the intraclass correlation value was 0.85. There were five components in the questionnaire with good construct validity. The scores of RMDQ had negatively correlated with sC-LKQ. Conclusion In the Chinese population, the sC-LKQ demonstrated excellent psychometric qualities and could be used to evaluate self-efficacy in clinical practice and research.

Abstract
INTRODUCTION AND HYPOTHESIS This study aimed to evaluate the relationship between pelvic floor muscle (PFM) strength and low back pain (LBP) in women with and without non-specific low back pain (NSLBP) with similar demographic and physical characteristics. METHODS The study included 40 women (35.73±6.74 years) with NSLBP (with LBP group) and 32 women (34.59±5.93) without LBP (without LBP group). PFM strength with a perineometer, pain intensity with a Visual Analog Scale (VAS), quality of life with the Short Form-36 (SF-36), and perceptions of LBP and related disability with the Rolland Morris Disability Questionnaire (RMDQ) were evaluated. RESULTS There was no difference between the groups in terms of age, BMI, number of births (0, 1, and 2 births) and mode of delivery (vaginal/cesarean section) (p>0.05). There was a statistical difference between the groups in all parameters except SF-36 Emotional Role Limitation subscale (p<0.05). We found PFM strength an independent predictor of the RMDQ score, and RMDQ and VAS scores as independent predictors of SF-36 physical and mental components (p<0.05). CONCLUSIONS Decreased PFM strength in women causes non-specific mechanical low back pain and disability independent of age, BMI, and the number and type of delivery. Decreased PFM strength is a predictor of disability. Disability and pain are also independent predictors of decreased quality of life. PFM measurement should be prioritized when evaluating women with NSLBP. PFM strength may be a determinant of LBP.

Abstract
Background Both acute and persistent pain is associated with anxiety in clinical observations, but whether the underlying neural mechanisms differ is poorly understood. Methods We used formalin or complete Freund's adjuvant (CFA) to induce acute or persistent pain. Behavioral performance was assessed by the paw withdrawal threshold (PWT), open field (OF), and elevated plus maze (EPM) tests. C-Fos staining was used to identify the activated brain regions. Chemogenetic inhibition was further performed to examine the necessity of brain regions in behaviors. RNA sequencing (RNA-seq) was used to identify the transcriptomic changes. Results Both acute and persistent pain could lead to anxiety-like behavior in mice. The c-Fos expression indicates that the bed nucleus of the stria terminalis (BNST) is activated only in acute pain, whereas the medial prefrontal cortex (mPFC) is activated only in persistent pain. Chemogenetic manipulation reveals that the activation of the BNST excitatory neurons is required for acute pain-induced anxiety-like behaviors. In contrast, the activation of the prelimbic mPFC excitatory neurons is essential for persistent pain-induced anxiety-like behaviors. RNA-seq reveals that acute and persistent pain induces differential gene expression changes and protein-protein interaction networks in the BNST and prelimbic mPFC. The genes relevant to neuronal functions might underline the differential activation of the BNST and prelimbic mPFC in different pain models, and be involved in acute and persistent pain-related anxiety-like behaviors. Conclusion Distinct brain regions and gene expression patterns are involved in acute and persistent pain-related anxiety-like behaviors.

Clinical outcome measures reporting in randomized trials evaluating Tuina therapy for chronic nonspecific low back pain: A systematic review. Medicine (Baltimore) 2023; 102:e33628. [PMID: 37083789 PMCID: PMC10118339 DOI: 10.1097/md.0000000000033628] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Accepted: 04/05/2023] [Indexed: 04/22/2023] Open
Abstract
BACKGROUND Tuina has gained widespread attention and utilization for the management of chronic nonspecific low back pain (CNLBP). However, evidence-based guidance for choosing accurate and appropriate outcome measures of Tuina is lacking. The objective of this study is to systematically synthesize the existing outcome measures reported in randomized controlled trials (RCTs) evaluating Tuina therapy in CNLBP. METHODS Electronic literature searches were conducted in multiple English and Chinese databases from their inception to May 2022. RCTs were included if they involved clinical outcome measures in Tuina treatment for patients with CNLBP. Outcome instruments for each study were extracted and analyzed. Evidence from included studies were assessed using the Cochrane risk-of-bias tool. RESULTS Of the 735 identified articles, 17 articles with 1628 participants were included. Measurement domains in these RCTs were mainly reported in terms of pain (94%) and physical activity (71%), followed by safety (41%), Chinese medicine outcome (35%), and quality of life (12%). Moreover, several limitations with existing outcomes were reported, including lack of emphasis on the evaluation of quality of life, inadequate safety monitoring, as well as insufficient and vague Chinese medicine outcome measures. All trials were deemed to be of poor methodological quality. CONCLUSION Pain and physical disability were the most frequently studied outcome domains in CNLBP treated by Tuina therapy. More rigorous and high-quality trials with appropriately selected outcome measures are needed in the future.

Abstract
The purpose of the present study was to establish the association between self-efficacy, perception of disease, emotional regulation, and fatigue and the health-related quality of life in older adults living in the departments of Cesar and Atlántico in Colombia and who have been diagnosed with a chronic disease. The participants were 325 older adults of both sexes, with literacy and no presence of cognitive impairment in the Mini-Mental State Examination (MMSE); A non-probabilistic sampling was carried out. We used the MOS-SF-36 questionnaire, the Brief Illness Perception Questionnaire scale for measuring the perception of disease, the Stanford Patient Education Research Center’s Chronic Disease Self self-efficacy questionnaire for chronic patients, the Difficulties in Emotional Regulation Scale, and the Fatigue Severity Questionnaire as measurement instruments. The design was non-experimental cross-sectional with a correlational scope. The results indicate that self-efficacy, disease perception, emotional regulation and severity of fatigue are variables that could impact the physical function of quality of life, confirming that self-efficacy would work as a factor that decreases the probability that a participant score low on this dimension of quality of life. On the other hand, both the perception of the disease and the severity of fatigue were identified as factors that probably negatively influence quality of life.

Abstract
This study aimed to evaluate the impact of low back pain on the perceived health-related quality of life of children between 6 and 12 years of age. This is a cross-sectional study of three hundred seventy-seven students from three schools (two private and one public) located in the city of Botucatu, São Paulo. Data were collected using the Pediatric Quality of Life Inventory (PedsQL, version 4.0), a questionnaire comprising questions on personal background, sociodemographic and socioeconomic information, and a questionnaire about quality of life. Comparisons were made between groups with and without low back pain. The chi-squared test was used for analyzing categorical variables, and the non-parametric Mann–Whitney test was used for continuous variables. According to the findings obtained in this study, it was observed that low back pain in the last month was reported by 27.3% of the total participants. The perceived health-related quality of life was lower among individuals who had low back pain, and the scores of physical and emotional functioning domains were also lower in the presence of low back pain. The prevalence of low back pain among children and adolescents is relatively high. Furthermore, the repercussions of low back pain may lead to a lower overall perception of the health-related quality of life in this population and affect aspects of physical and emotional functioning.

Abstract
PURPOSE Both spondyloarthritis and chronic low back pain (CLBP) significantly impact health-related quality of life (HRQoL). It is important to clarify whether these disorders have different impacts on the several domains of HRQoL as different mechanisms may necessitate different treatment interventions. Moreover, the factors associated with HRQoL can inform more targeted group interventions to promote HRQoL. METHODS We used data from EpiReumaPt, a population-based survey conducted from September 2011 to December 2013. HRQoL was assessed with EuroQoL-5-Dimensions (EQ-5D). Spondyloarthritis was diagnosed by expert opinion (rheumatologist) and predefined criteria. CLBP was diagnosed if low back pain was present on the day of the interview and persisted for > 90 days. Univariable and multivariable linear regression analyses compared HRQoL among subjects with spondyloarthritis, CLBP, and no rheumatic diseases. Multivariable linear regression analyses evaluated HRQoL factors in spondyloarthritis and CLBP subjects. RESULTS We included 92 spondyloarthritis patients, 1376 CLBP patients, and 679 subjects without rheumatic diseases. HRQoL was similarly affected in spondyloarthritis and CLBP (ß = - 0.03, 95% CI [- 0.08; 0.03]) in all EQ5D dimensions. A much lower HRQoL was found in spondyloarthritis and CLBP patients compared with subjects without rheumatic diseases (ß = - 0.14, 95% CI [- 0.19; - 0.10]; ß = - 0.12, 95% CI [- 0.14; - 0.09], respectively). In spondyloarthritis subjects, multimorbidity and active disease were associated with worse HRQoL (ß = - 0.18; 95% CI [- 0.24; 0.03]; ß = - 0.13; 95% CI [- 0.29; - 0.05], respectively), and regular physical exercise was associated with better HRQoL (ß = 0.18; 95% CI [0.10; 0.30]). In CLBP subjects, multimorbidity (β = - 0.11; 95% CI [- 0.14; - 0.08]), obesity (β = - 0.04; 95% CI [- 0.08; - 0.01]), and low back pain intensity (β = - 0.02; 95% CI [- 0.03; - 0.02]) were associated with worse HRQoL, and regular physical exercise (β = 0.08; 95% CI [0.05; 0.11]) was significantly associated with better HRQoL. CONCLUSION Spondyloarthritis and CLBP subjects reported similar levels of impairment in the mental, physical, and social domains of HRQoL. Future health plans should address modifiable factors associated with HRQoL in these conditions to achieve better outcomes.

Abstract
Chronic low back pain, defined as low back pain lasting more than 3 months, is a globally prevalent health problem with significantly high medical and economic burden on individuals and the society. This study aimed to estimate the prevalence of chronic low back pain and examine its association with health outcomes including physical function, mental health, and quality of life among adult population in Singapore. Cross-sectional secondary data analysis was performed using baseline data of the 1941 adults (mean age: 52.6 years, range: 21-97 years) from a representative population health survey conducted in the Central region of Singapore. Those with self-reported chronic low back pain in past six months were identified. The Late-Life Function and Disability Instrument, Patient Health Questionnaire-9, and EQ-5D-5L were used to measure physical function and limitation, mental health, and health-related quality of life, respectively. Generalized Linear Regressions were used to examine the association of chronic low back pain with physical function, limitation, depressive symptoms, and health-related quality of life. There were 8.1% (n = 180) participants reporting having chronic low back pain in past six months, among whom 80.5% sought treatments at either primary care, specialist outpatient, or Traditional Chinese Medicine clinics. Individuals with chronic low back pain reported poorer physical function, more limitations in performing major life tasks and social activities, more depressive symptoms, and lower health-related quality of life (all p < 0.01), even after adjusting for socio-demographics, lifestyle factors, and number of morbidities. The prevalence of chronic low back pain was 8.1% among the study population. Chronic low back pain was associated with poorer physical function, more limitations and depressive symptoms, and lower health-related quality of life. The findings highlight the significant impact of chronic low back pain on physical function and limitation, mental health, and health-related quality of life in a general population. Increased awareness on prevention, early and proper management of low back pain, and rehabilitation policies are required to better tackle the burden of low back pain at the population level.

Abstract
BACKGROUND To observe the effects of vitamin D on the apoptotic human nucleus pulposus cells under tumor necrosis factor-α (TNF-α) treatment. METHODS The gene expression data was downloaded from the NCBI Gene Expression Omnibus (GEO) database ( https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE34095 ). Differentially expressed genes between degenerative disc and non-degenerative disc were performed by R software. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genome (KEGG) pathway enrichment analyses were performed using The Database for Annotation, Visualization and Integrated Discovery (DAVID). Then, the human nucleus pulposus tissue was harvested from 12 patients according to the modified Pfirrmann classification and human nucleus pulposus cells were obtained from digestion of herniated nucleus pulposus tissue. The collected nucleus pulposus cells were treated with different concentration of TNF-α, and cellular apoptosis was measured by flow cytometry. Then, human nucleus pulposus cells were divided into following groups: normal culture medium, TNF-α treated, TNF-α, and vitamin D-treated groups. Cellular apoptosis rate was quantified by flow cytometry. Protein expression of p-p65, p65, and IkBa was detected with western blot analysis. RESULTS A total of 536 differentially expressed genes were identified through bioinformatic analysis. KEGG pathway revealed that NF-kB signaling pathway was involved in the process of disc degeneration. In the NP cell cultures, vitamin D significantly increased cell proliferation potency. Furthermore, vitamin D inhibited TNF-α induced apoptosis of human nucleus pulposus cells. Vitamin D reduced the phospho-NF-κB/p65 expression in the TNF-α-treated NP cells. CONCLUSION Vitamin D can attenuate TNF-α-induced NP cells apoptosis through interfering with the NF-κB pathway.
