ABSTRACT

OBJECTIVE To study the improvement effect and mechanism of sanguinarine (SG) on inflammatory pain in rats with lumbar disc herniation (LDH) and its mechanism. METHODS LDH model rats were established and divided into model group, SG low-dose, medium-dose and high-dose groups (1.00, 2.50, 6.25 mg/kg), high-dose of SG+Anisomycin [mitogen-activated protein kinase (MAPK) activator] group (6.25 mg/kg SG+5 mg/kg Anisomycin), with 10 rats in each group. Another 10 rats were included as the control group. Each group was given corresponding drugs intraperitoneally, while the control group and model group were given an equal volume of normal saline intraperitoneally, once a day, for 7 consecutive days. The general situation and neurological changes of rats in each group were observed, and the pain threshold [including paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL)] of rats was determined; the histopathological changes of dorsal root ganglion (DRG) were observed in rats. The serum levels of inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β)] and pain factors [neuropeptide Y (NPY), 5-hydroxytryptamine (5-HT)] in rats were detected.The positive expressions of ionized-calcium binding adaptor molecule-1 (Iba-1) in spinal cord microglia and glial fibrillary acidic protein (GFAP) in astrocytes were observed. The expressions of proteins related to MAPK/extracellular signal-regulated kinase (ERK)/nuclear factor κB (NF-κB) signaling pathway, TNF-α and IL-1β proteins were detected in DRG tissue of rats. RESULTS Compared with the control group, the rats in the model group showed decreased appetite, hindlimb movement disorders, and disordered neuronal cell arrangement, the neurological score, the levels of TNF-α, IL-1β, NPY, the positive expressions of Iba-1 and GFAP, the phosphorylations of p38 MAPK, ERK1/2 and NF-κB p65, the protein expressions of TNF-α and IL-1β were significantly increased (P<0.05); PWMT, PWTL and the levels of 5-HT were significantly reduced (P<0.05). Compared with the model group, the rats of SG groups showed some relief in their mental appetite and hindlimb motor disorders, the intervertebral disc structure of DRG was restored, and the levels of the above quantitative indicators had significantly reversed (P<0.05). Anisomycin reversed the improvement effect of SG on inflammatory pain in LDH rats. CONCLUSIONS SG can improve inflammatory pain by inhibiting the activation of microglia in DRG tissue of LDH rats, reducing the release of inflammatory factors, and increasing pain threshold, and its mechanism of action may be related to the inhibition of MAPK/ERK/NF- κB signaling pathway.

ABSTRACT

Objective To compare the efficacy of percutaneous transforaminal approach and translaminar approach in the treatment of L5/S1 disc herniation(LDH)under endoscopic discectomy.Methods Adopted a retro-spective case-control study,and selected 62 cases of patients with L5/S1 LDH who were treated with percutaneous endoscopic surgery in the spine surgery department of our hospital from June 2020 to December 2022,and the transforaminal approach was used.(TELD)in 32 cases(TELD group),and interlaminar approach(IELD)in 30 cases(IELD group).The observation indicators included intraoperative fluoroscopy times,operation time,hospitaliza-tion days,hospitalization expenses,leg pain VAS score,ODI score,modified MacNab curative effect evaluation and complications.Results All 62 patients successfully completed the operation and follow-up,and no serious complications occurred.There were statistically significant differences in operation time,fluoroscopy times,and hospitalization expenses between the two groups(P<0.001),but there was no significant difference in hospitaliza-tion days between the two groups(P>0.05).The lower extremity VAS scores at the last follow-up and the last follow-up were significantly improved compared with those before operation(P<0.001),and the ODI scores of the two groups were significantly improved at 2 days,1 month and at the last follow-up(P<0.001).At the same time point,there was no statistical difference(P>0.05);there was no significant difference in the excellent and good rate of surgery between the two groups(P>0.05).11 patients with high iliac crest in the TELD group successfully completed the surgery.Conclusions Both the endoscopic surgery through the intervertebral foramen and the inter-laminar approach can achieve satisfactory results in the treatment of L5/S1 LDH.However,local anesthesia through the intervertebral foramen approach reduces hospitalization costs,and patients with high iliac crest can successfully complete the surgery by selecting a suitable puncture path.The translaminar approach has fewer fluoroscopy times and shorter surgical time,but there is a higher risk of dura mater and nerve damage,which requires careful opera-tion for beginners.

ABSTRACT

BACKGROUND:Endoscopic treatment of lumbar disc herniation has obvious advantages over traditional open surgery.Endoscopic surgery involves the implantation of a working cannula,which requires only partial bone removal,and there are no studies on the effects of two types of intraoperative foraminoplasty and laminoplasty on the mechanical properties of the local structure of the lumbar spine. OBJECTIVE:To compare the effect of foraminoplasty and laminoplasty on the biomechanical properties of disc and isthmus of the responsible segment. METHODS:The lumbosacral CT images of a healthy male volunteer were taken,and a finite element model M0 of the L3 to sacral vertebrae was established,on which the primary and secondary foraminoplasty models M1 and M2 of the L5/S1 and the laminoplasty model M3 were built.The same load was applied to compare the intervertebral motion range,disc Von Mises stress and equivalent stress characteristics of L5 vertebral isthmus with each model. RESULTS AND CONCLUSION:(1)Compared with M0,M1 and M2 motion range in L5/S1 segment did not change significantly in all directions;M2 overall motion range increased by 8.60%in flexion;M3 increased by 8.23%and 8.26%in L5/S1 right bending and right torsion,and 5.39%and 5.67%in overall motion range in flexion and right bending,with no significant changes in motion range in the rest of working conditions.(2)Compared with M0,M1 showed no significant change in the extremes of Von Mises stress at L5/S1 disc;M2 increased 11.06%,12.50%,18.32%,and 15.48%in flexion,extension,left torsion,and right torsion;M3 increased 12.22%,19.54%,10.05%,and 9.97%in flexion,extension,left torsion,and right torsion,and the rest working conditions and L4/5 disc maximum Von Mises stress did not change significantly.(3)Compared to M0,the maximum Von Mises stress in the left isthmus of L5 of M1 increased by 12.43%in left bending,18.38%,13.29%,13.62%,and 40.00%in the right isthmus in extension,right bending,left torsion,and right torsion.The maximum Von Mises stress in the left isthmus of L5 of M2 increased by 38.87%,42.63%,16.95%,and 19.35%,and that in the right isthmus increased by 12.58%,33.70%,12.92%,and 17.42%in flexion,extension,left bending,and left torsion.The maximum Von Mises stress in the left isthmus of L5 of M3 increased 67.07%,78.14%,32.33%,62.94%,and 89.99%in flexion,extension,left and right bending,and right torsion.(4)The results suggest that foraminoplasty and laminoplasty have a small effect on spinal motion range;there is a mild increase in the extreme values of disc Von Mises stress in the segments operated by interbody laminoplasty and secondary foraminoplasty;there is no significant change in the extreme values of disc Von Mises stress in adjacent segments,and there is a significant increase in the Von Mises stress in the ipsilateral isthmus operated by the interbody laminoplasty model.

ABSTRACT

BACKGROUND:One-hole split endoscope technique has been widely used in the treatment of lumbar degenerative diseases,but there is no relevant literature on the safety analysis of this technique in the treatment of upper lumbar disc herniation. OBJECTIVE:To observe the position relationship of nerve roots,intervertebral space and bone landmarks in the upper lumbar spine by three-dimensional lumbar CT reconstruction technology,and to provide a basis for the clinical operation of one-hole split endoscope surgery. METHODS:Twenty-six patients with upper lumbar disc herniation underwent a lumbar CT scan.Mimics 17.0 software was imported to measure the related imaging parameters of L1/2 to L3/4 segments:(1)Measurement of vertical distance:In coronal view,the distance(a)from the intersection point of the medial facet of the superior articular process and the superior endplate(N)to the apex of the articular process(S);in the coronal view,the distance(b)from the sagittal intersection(M)of N and the inferior endplate to the apex of the inferior articular process(X).(2)Measured horizontal distance:the distance(c)between the cross-section of N and the lower edge of the outlet nerve root(N2);distance(d)between the cross-section of N and the intersection point of neural tissue(N1);N1 to N2 distance(e);distance(f)between the cross-section of M and the lateral edge of the nerve tissue(M1);M to M cross-section and exit nerve root intersection(M2)distance(g);distance(h)from M1 to M2;distance(i)from M2 to N1;distance(j)from the posterior edge of the articular surface(R)to M2 in sagittal view of the superior articular process. RESULTS AND CONCLUSION:(1)With the decrease of the segment,the distances a and b gradually increased,and the distance j gradually decreased.There was no significant difference between L1/2 and L2/3 segments(P>0.05).(2)With the decrease of the segment,distance d first decreased and then increased;distance f gradually decreased;distances c,e,g,h and i gradually increased;and there was no significant difference between L2/3 and L3/4 segments(P>0.05).(3)Distance i was the shortest distance without pulling nerve roots in the natural state,and the area of the safety zone was between four points M1,M2,N1,and N2.The bone was removed to the upper and lower endplates by biting the bone downward and upward through S and X,respectively,to expose the intervertebral space,and the window of distance g to M2 could be opened outward to avoid injury of the outlet nerve roots.(4)In conclusion,the upper lumbar vertebrae have unique anatomical characteristics.Based on the relevant measurements of nerve roots,spinal dura and intervertebral space,the parameters of the one-hole split endoscope technique are more accurate and safe during operation.

ABSTRACT

BACKGROUND:Previous studies have shown the correlation between lumbosacral sagittal plane parameters and natural absorption of lumbar disc herniation.However,the lumbosacral sagittal plane parameters included lumbar lordosis angle,lumbosacral joint angle,sacral inclination angle and many other parameters.The effects of each parameter on the natural absorption of the herniated disc were different.In addition,there are few studies on the reabsorption of a specific segment of intervertebral disc herniation at present,and most of the measured data are obtained from digital radiography or CT,while the correlation between lumbosacral sagittal plane parameters measured from MRI and reabsorption after L5/S1 intervertebral disc herniation is rarely reported. OBJECTIVE:To study the corresponding changes of lumbar sagittal plane parameters after L5/S1 intervertebral disc herniation reabsorption and to screen out the lumbosacral sagittal plane parameters with the most significant changes during intervertebral disc reabsorption. METHODS:Totally 57 patients with lumbar disc herniation who had complete MRI image data were selected and met the diagnostic criteria for lumbar disc herniation and only received non-surgical treatment for reabsorption of L5/S1 protrusion segments.MRI measured the protrusion area of the maximum protrusion plane in the coronal plane,lumbosacral sagittal plane parameters[lumbar curvature index,lumbar lordosis(α),L5/S1 disc angle(β),intervertebral height measurement,lumbosacral joint angle,sacral platform angle,sacral inclination angle,and lower lumbar lordosis angle].Besides,lumbosacral sagittal plane parameters were ranked in the importance of variables by random forest model in R software,and then significant variables were fitted with multiple linear regression.The changes between parameters before and after treatment were analyzed and compared by paired sample t-test. RESULTS AND CONCLUSION:(1)A total of 57 patients with L5/S1 lumbar disc herniation were included in this study,and the symptoms and imaging features of the patients were significantly relieved to a large extent.(2)Before treatment,there were 4 cases of grade 1,29 cases of grade 2 and 24 cases of grade 3 according to the Classification of Michigan State University.After treatment,there were 48 cases of grade 1 and 9 cases of grade 2.(3)The random forest model suggested that intervertebral height,lumbar curve index,sacral inclination angle,and lower lumbar lordosis angle changed significantly in L5/S1 disc herniation reabsorption,and the order of their change significance was lumbar curve index>intervertebral space height>sacral inclination angle>lower lumbar lordosis angle.(4)Lumbar curve index,lumbar lordosis and sacral platform angle increased,with statistical significance(P<0.05).There were no significant differences in disc angle,intervertebral height,lower lumbar lordosis angle,sacral inclination angle or lumbosacral joint angle(P>0.05).(5)Lumbar curvature index was the most significant parameter of the lumbosacral sagittal plane in herniated disc reabsorption.In addition,lumbar curve index,sacral inclination angle,and lower lumbar lordosis angle are commonly used clinically to describe the change of lumbar curvature,suggesting that L5/S1 disc herniation reabsorption is correlated with the change of lumbar curvature.It is indicated that in the treatment of lumbar disc herniation,a clinical cure can be achieved by improving or restoring the disordered lumbar curvature.

ABSTRACT

BACKGROUND:Based on different algorithms of machine learning,how to carry out clinical research on lumbar disc herniation with the help of various algorithmic models has become a trend and hot spot in the development of intelligent medicine at present. OBJECTIVE:To review the characteristics of different algorithmic models of machine learning in the diagnosis and treatment of lumbar disc herniation,and summarize the respective advantages and application strategies of algorithmic models for the same purpose. METHODS:The computer searched PubMed,Web of Science,EMBASE,CNKI,WanFang,VIP and China Biomedical(CBM)databases to extract the relevant articles on machine learning in the diagnosis and treatment of lumbar disc herniation.Finally,96 articles were included for analysis. RESULTS AND CONCLUSION:(1)Different algorithm models of machine learning provide intelligent and accurate application strategies for clinical diagnosis and treatment of lumbar disc herniation.(2)Traditional statistical methods and decision trees in supervised learning are simple and efficient in exploring risk factors and establishing diagnostic and prognostic models.Support vector machine is suitable for small data sets with high-dimensional features.As a nonlinear classifier,it can be applied to the recognition,segmentation and classification of normal or degenerative intervertebral discs,and to establish diagnostic and prognostic models.Ensemble learning can make up for the shortcomings of a single model.It has the ability to deal with high-dimensional data and improve the precision and accuracy of clinical prediction models.Artificial neural network improves the learning ability of the model,and can be applied to intervertebral disc recognition,classification and making clinical prediction models.On the basis of the above uses,deep learning can also optimize images and assist surgical operations.It is the most widely used model with the best performance in the diagnosis and treatment of lumbar disc herniation.The clustering algorithm in unsupervised learning is mainly used for disc segmentation and classification of different herniated segments.However,the clinical application of semi-supervised learning is relatively less.(3)At present,machine learning has certain clinical advantages in the identification and segmentation of lumbar intervertebral discs,classification and grading of the degenerative intervertebral discs,automatic clinical diagnosis and classification,construction of the clinical predictive model and auxiliary operation.(4)In recent years,the research strategy of machine learning has changed to the neural network and deep learning,and the deep learning algorithm with stronger learning ability will be the key to realizing intelligent medical treatment in the future.

ABSTRACT

BACKGROUND:Pain mechanisms in patients with lumbar disc herniation are associated with inflammation,autophagy is closely related to intervertebral disc diseases and inflammatory response,and aberrant miR-206 expression can trigger skeletal diseases. OBJECTIVE:To investigate the mechanism of miR-206 on inflammation,analgesia and autophagy related proteins in nucleus pulposus in rats with lumbar disc herniation. METHODS:Sixty SPF male Sprague-Dawley rats were randomly divided into control group,model group,miR-206 mimics-NC group,miR-206 mimics group,miR-206 inhibitor-NC group and miR-206 inhibitor group.Animal models of lumbar disc herniation were established except for the control group.Ten days after modeling,miR-206 mimics-NC group,miR-206 mimics group,miR-206 inhibitor-NC group and miR-206 inhibitor group were injected with miR-206 mimics-NC(20 μmol/L,10 μL),miR-206 mimics(20 μmol/L,10 μL),miR-206 inhibitor-NC(20 μmol/L,10 μL)and miR-206 inhibitor(20 μmol/L,10 μL),respectively.Administration was given once a day for 4 continuous days.The control group and model group were injected with the same dose of normal saline.The paw withdrawal mechanical threshold of bilateral hind feet was measured by Von Frey filaments,and the paw withdrawal thermal latency of bilateral hind feet was measured by heat pain tester.The morphology of dorsal root ganglia was observed by hematoxylin-eosin staining.The expressions of inflammatory factors phospholipase A2,cyclooxygenase 2,prostaglandin E2,tumor necrosis factor α,and interleukin 1β in nucleus pulposus were detected by qPCR.The expressions of autophagy-related proteins LC3I and Beclin-1 were detected by western blot assay. RESULTS AND CONCLUSION:At 3,7,and 14 days after modeling,the paw withdrawal mechanical threshold and paw withdrawal thermal latency were both decreased in the model group compared with the control group,while the levels of phospholipase A2,cyclooxygenase 2,prostaglandin E2,tumor necrosis factor α,interleukin 1β,LC3I and Beclin-1 increased(P<0.05).The above indexes showed no significant changes in the miR-206 inhibitor-NC group and miR-206 mimics-NC group compared with the model group(P>0.05).Compared with the miR-206 mimics-NC group,the miR-206 mimics group had lower paw withdrawal mechanical threshold and paw withdrawal thermal latency and higher levels of phospholipase A2,cyclooxygenase 2,prostaglandin E2,tumor necrosis factor α,interleukin 1β,LC3I,and Beclin-1 levels(P<0.05).Compared with the miR-206 inhibitor-NC group,the rats in the miR-206 inhibitor group showed opposite changes in the above indicators,and there were significant differences between the two groups(P<0.05).To conclude,inhibition of miR-206 can significantly improve the level of inflammatory factors in nucleus pulposus of rats with lumbar disc herniation,increase pain threshold,and reduce autophagy.The mechanism is related to the inhibition of LC3I and Beclin-1 expression.

ABSTRACT

BACKGROUND:Platelet-rich plasma can promote the repair and regeneration of intervertebral disc tissue.Percutaneous transforaminal endoscopic discectomy is widely used in the treatment of lumbar disc herniation.In recent years,more and more scholars have focused on the combined treatment of lumbar disc herniation with the two techniques in order to achieve a better patient prognosis. OBJECTIVE:To investigate the clinical safety and effectiveness of percutaneous transforaminal endoscopic discectomy combined with platelet-rich plasma in the treatment of lumbar disc herniation. METHODS:The clinical data of 58 patients with lumbar disc herniation who met the inclusion and exclusion criteria at Sixth Medical Center of PLA General Hospital from June 2017 to May 2018 were retrospectively analyzed.Among them,29 patients underwent percutaneous transforaminal endoscopic discectomy combined with platelet-rich plasma(observation group),and the remaining 29 patients underwent percutaneous transforaminal endoscopic discectomy only(control group).Visual Analogue Scale score for back and leg pain,lumbar JOA score,and Oswestry Disability Index were evaluated preoperatively,at 3,6,and 12 months postoperatively,and at the last follow-up.Intervertebral space height,nucleus pulposus to cerebrospinal fluid signal strength ratio,and intervertebral disc Pfirrmann grading were measured preoperatively,at 6 and 12 months postoperatively,and at the last follow-up.The modified MacNab criteria were used to assess excellent and good rate of curative effect at the last follow-up. RESULTS AND CONCLUSION:(1)The Visual Analogue Scale score for back and leg pain,JOA score,and Oswestry Disability Index of the two groups postoperatively were significantly improved compared with those preoperatively(P<0.05).Visual Analogue Scale score and Oswestry Disability Index were lower in the observation group than those in the control group at 3 and 6 months postoperatively(P<0.05).The JOA score was higher in the observation group than that in the control group at 3 and 6 months postoperatively(P<0.05).(2)The nucleus pulposus to cerebrospinal fluid signal strength ratio was higher in the observation group than that in the control group at the last follow-up(P<0.05).Pfirrmann grading of the intervertebral discs was better in the observation group than that in the control group(P<0.05).The excellent and good rate was 93%in the observation group and 83%in the control group,and the difference was not statistically significant(P>0.05).(3)These findings indicate that percutaneous transforaminal endoscopic discectomy combined with platelet-rich plasma in the treatment of lumbar disc herniation has satisfactory clinical efficacy and can delay the degeneration of the intervertebral disc to a certain extent.

ABSTRACT

BACKGROUND:Studies have shown that insulin-like growth factor 1/platelet-derived growth factor has an inhibitory effect on fibroblast apoptosis.miR-141-3p in bone marrow stromal cells increases with age and has a relationship with the activation of inflammatory signaling pathways,suggesting that it may be a therapeutic target for lumbar disc herniation. OBJECTIVE:To explore the effects of miR-141-3p on dorsal root ganglion inflammation and lower limb pain in rats with lumbar disc herniation by regulating insulin-like growth factor 1/platelet-derived growth factor. METHODS:Fifty male Sprague-Dawley rats,SPF level,were randomly divided into normal group,model group,miR-NC group,miR-141-3p inhibitor group and miR-141-3p mimics group,with 10 rats in each group.Except for the normal group,animal models of lumbar disc herniation were established in rats by autologous nucleus pulposus transplantation.After successful modeling,rats in the miR-NC,miR-141-3p inhibitor and miR-141-3p mimics groups were injected intrathecally with 10 μL of 20 μmol/L miR-NC,miR-141-3p inhibitor,miR-141-3p mimics,once a day for 28 days,respectively,while those in the normal and model groups were injected with the same volume of saline at the same location at the same time.Paw withdrawal thermal latency threshold was used to evaluate lower limb pain in rats.The mRNA expression of miR-141-3p in dorsal root ganglion tissue was detected by real-time fluorescence quantitative PCR,the levels of inflammatory factors in dorsal root ganglion tissue were detected by ELISA,and the expression of insulin-like growth factor 1/platelet-derived growth factor in dorsal root ganglion tissue was detected by western blot.The correlation between miR-141-3p and insulin-like growth factor 1/platelet-derived growth factor was analyzed. RESULTS AND CONCLUSION:There were no significant differences in all indexes between the miR-NC group and the model group.Paw withdrawal thermal latency threshold was significantly lower in the model group than in the normal group(P<0.05),significantly lower in the miR-141-3p inhibitor group than the miR-NC group(P<0.05),and significantly higher in the miR-141-3p mimics group than in the miR-141-3p inhibitor group(P<0.05).The mRNA expression of miR-141-3p in dorsal root ganglion tissue was significantly lower in the model group than in the normal group(P<0.05),significantly lower in the miR-141-3p inhibitor group than in the miR-NC group(P<0.05),and significantly higher in the miR-141-3p mimics group than in the miR-141-3p inhibitor group(P<0.05).The levels of tumor necrosis factor α,interleukin 1β,and interleukin 1 in dorsal root ganglion tissue were significantly higher in the model group than in the normal group(P<0.05),significantly higher in the miR-141-3p inhibitor group than in the miR-NC group(P<0.05),and significantly lower in the miR-141-3p mimics group than in the miR-141-3p inhibitor group(P<0.05).The protein expressions of insulin-like growth factor 1 and platelet-derived growth factor in dorsal root ganglion tissue were significantly lower in the model group than in the normal group(P<0.05),significantly lower in the miR-141-3p inhibitor group than in the miR-NC group(P<0.05),and significantly higher in the miR-141-3p mimics group than in the miR-141-3p inhibitor group(P<0.05).The expressions of insulin-like growth factor 1 and platelet-derived growth factor showed a positive correlation with miR-141-3p(r=0.904,P<0.001;r=0.879,P<0.001).To conclude,miR-141-3p can significantly improve lower limb pain and inhibit inflammation in dorsal root ganglia in rats with lumbar disc herniation,and its mechanism may be related to the promotion of insulin-like growth factor 1/platelet-derived growth factor expression.

ABSTRACT

BACKGROUND:With the progress of minimally invasive procedures of the spine,endoscopic lumbar decompression has been widely used in the treatment of lumbar disc herniation.The indications of different endoscopic surgical approaches are different,and the decision of the specific operation plan needs to be combined with the actual situation and the choice of clinical surgeons. OBJECTIVE:To investigate the short-term effect in treatment of single-level lumbar disc herniation by percutaneous endoscopic visual trephine arthroplasty. METHODS:Ninety patients with single-level lumbar disc herniation admitted to Affiliated Hospital of Xuzhou Medical University from January 2019 to December 2021 who met the inclusion criteria were included in this study.According to different approaches of percutaneous endoscopic visual trephine arthroplasty,they were divided into transforaminal approach group(control group,n=48 cases)and translaminar approach group(trial group,n=42 cases).The general information of patients in the two groups was recorded,including sex,age,disease course,body mass index,incision length,operation time,intraoperative fluoroscopy times,length of hospital stay,and amount of blood loss.Visual analog scale score of pain and Japanese Orthopaedic Association score at different follow-up stages were assessed.The modified MacNab standard was used to evaluate the clinical outcome at the last follow-up,and the postoperative complications and recurrence rate were measured. RESULTS AND CONCLUSION:(1)The operation time and intraoperative fluoroscopy times of the trial group were less than those of the control group,and the difference was statistically significant(P<0.05).However,there were no significant differences in intraoperative blood loss,incision length,and hospital stay between the two groups(P>0.05).(2)There was no significant difference in visual analog scale score of pain and Japanese Orthopaedic Association score between the two groups before surgery(P>0.05).However,visual analog scale of pain and Japanese Orthopaedic Association score were significantly improved 1 week,3,6,and 12 months after surgery(P<0.05).(3)At the last follow-up,the good and good rate of modified MacNab standard was 94%in the control group and 95%in the trial group.(4)In the control group,one patient still felt back and leg pain after surgery,underwent open surgery,and recovered well after surgery without obvious sequelae.There were no postoperative complications or recurrent cases in the trial group.(5)It is concluded that both percutaneous transforaminal approach and interlaminar approach have good short-term clinical efficacy and high patient satisfaction in the treatment of single-level lumbar disc herniation,but the time of the interlaminar approach is shorter and has less intraoperative fluoroscopy times.

METHODS:(1)Network pharmacological analysis:We obtained the active ingredients and targets of Yougui Pill from TCMSP and other databases,collected genes related to lumbar disc herniation from GeneCards database,and took the intersection of the two for the topological analysis to derive the main active ingredients and core therapeutic targets.Gene ontology function analysis and Kyoto encyclopedia of genes and genomes pathway enrichment analysis were performed using R software.(2)Molecular docking:Autodock and Pymol software were utilized for the prediction of molecular binding energy of TCM active ingredients to core therapeutic targets.(3)Animal experiments:Eighteen Sprague-Dawley rats were randomly divided into a control group,a degeneration group and a Yougui Pill group,with 6 rats in each group.A rat model of intervertebral disc degeneration was prepared by fiber puncture method in the degeneration and Yougui Pill groups.At 2 weeks after modeling,Yougui Pill was given by gavage in the Yougui Pill group,once a day for 2 consecutive weeks.The level of tumor necrosis factor-α in serum was detected by the ELISA method,and morphological changes of the annulus fibrosus and nucleus pulposus cells were observed using hematoxylin-eosin staining. RESULTS AND CONCLUSION:There were 90 active ingredients and 64 targets,and the main active ingredients were found to be quercetin,kaempferol,β-carotene,soybean flavonoid,and 4'-O-methylnyasol.The core targets of Yougui Pill for the treatment of lumbar disc herniation were interleukin 6,tumor necrosis factor-α,AKT1,interleukin 1B,and vascular endothelial growth factor A.Enrichment analysis revealed that the intersecting genes might be expressed through the interleukin-17 signaling pathway,tumor necrosis factor signaling pathway,MAPK signaling pathway,PI3K-AKT signaling pathway,and other signaling pathways to improve intervertebral disc degeneration.The molecular docking test verified that quercetin,kaempferol,and β-carotene had strong binding ability to the core targets.Animal experiments showed that the level of serum tumor necrosis factor α in the degeneration group was higher than that in the control group(P<0.05),and the level of serum tumor necrosis factor α in the Yougui Pill group was lower than that in the degeneration group(P<0.05).Hematoxylin-eosin staining showed that the fibrous annulus of the intervertebral discs and the structure of the nucleus pulposus in the degeneration group were destroyed,and the number of nucleus pulposus cells was reduced;there was a tendency to reconstructing the fibrous annulus of the intervertebral discs in the Yougui Pill group,and the number of nucleus pulposus cells increased compared with the degeneration group.To conclude,Yougui Pill may treat lumbar disc herniation by improving disc degeneration through the effects of quercetin,kaempferol,beta-carotene and other key active ingredients on core targets such as tumor necrosis factor.

ABSTRACT

BACKGROUND:In the research on acupuncture treatment for lumbar disc herniation,most acupuncture treatments are performed under CT guidance or without guidance.The precise control of the target site and the effective acupuncture location are not clear. OBJECTIVE:To observe the clinical effects of acupuncture at Jiaji points under ultrasonic guidance in treating lumbar disc herniation. METHODS:A total of 70 cases of lumbar disc herniation,36 males and 34 females aged 18-65 years old,were selected from Chinese PLA General Hospital and Third Affiliated Hospital of Beijing University of Chinese Medicine.They were divided into trial group and control group by random number table method,with 35 cases in each group.The control group received acupuncture at Jiaji points.The trial group received acupuncture at Jiaji points under ultrasonic guidance.The patients were treated once on the day of treatment and 4,7 days after treatment.Visual analog scale score,Oswestry disability index,Japanese Orthopaedic Association score,and MOS 36-Item Short-Form Health Survey(SF-36)were evaluated before and after treatment. RESULTS AND CONCLUSION:(1)Compared with before treatment,the visual analog scale scores of both groups were decreased after treatment(P<0.01).Compared with the control group,the visual analog scale scores of the trial group were decreased on days 2,3,6,7 of treatment and 1,2 weeks after the end of treatment(P<0.05,P<0.01).(2)Compared with before treatment,Oswestry disability index after treatment was decreased in both groups(P<0.01).Compared with the control group,Oswestry disability index of the trial group was decreased from days 1 to 7 of treatment and 1,2 weeks after treatment(P<0.01).(3)Compared with before treatment,the Japanese Orthopaedic Association scores of both groups were increased after treatment(P<0.01).Compared with the control group,the Japanese Orthopaedic Association scores of the trial group were increased on days 3,7 of treatment and 1,2 weeks after treatment(P<0.05,P<0.01).(4)Compared with before treatment,SF-36 scores in both groups were increased after treatment(P<0.01).There was no significant difference in SF-36 scores between the two groups after treatment(P>0.05).(5)These results show that acupuncture at Jiaji points has curative effect on lumbar disc herniation,and ultrasonic guidance could improve the clinical curative effect of acupuncture at Jiaji points for lumbar disc herniation.

ABSTRACT

OBJECTIVE To investigate the effects and mechanism of Yiqi huoxue decoction (YQHX) on lumbar disc herniation in rats. METHODS Rats were randomly divided into sham operation group, model group, NF-κB inhibitor group (QNZ group, 1 mg/kg), YQHX group (9.1 g/kg) and combination group (YQHX+QNZ group, the same dose as each single drug group), with 10 rats in each group. Except for sham operation group, lumbar disc herniation model of rats was induced in other groups; administration groups were given QNZ intraperitoneally or/and YQHX intragastrically, once a day, for 8 consecutive weeks. The severity of intervertebral disc herniation was evaluated in each group; the pathological changes of intervertebral discs and the changes of autophagy of nucleus pulposus cells were all observed; the level of tumor necrosis factor-α (TNF-α) in serum, and the ratios of Bcl-2/adenovirus E1B interacting protein 3 (BNIP3) and Beclin-1 positive cells in intervertebral disctissues were detected; the phosphorylation of nuclear factor-κB (NF-κB) p65, the expressions of tumor necrosis factor receptor- associated factor-2 (TRAF-2), TRAF-3, BNIP3 and LC3B protein, and mRNA expressions of NF-κB p65, LC3B, p62,BNIP3 and Beclin-1 were determined. RESULTS Compared with model group, Pfirrmann grading score decreased significantly,the pathological injury of intervertebral disc tissue was relieved in YQHX group; the number of autophagosomes in nucleus pulposus cells increased; serum level of TNF-α and mRNA expression of p62 in intervertebral disc tissue decreased significantly; the ratios of BNIP3 and Beclin-1 positive cells, the phosphorylation of NF-κB p65, the expressions of TRAF-2, TRAF-3, BNIP3 and LC3B protein as well as the mRNA expressions of NF- κB p65, LC3B, BNIP3 and Beclin-1 decreased significantly in intervertebral disc tissues (P<0.05). The changes of above indexes in YQHX group were reversed partly in YQHX+QNZ group. CONCLUSIONS YQHX promotes the elevation of autophagy level of intervertebral discs, slows down the inflammatory response and the progression of lumbar disc herniation by activating the NF-κB signaling pathway.

ABSTRACT

ObjectiveTo evaluate the clinical effectiveness and safety of acupuncture with manipulation for lumbar disc herniation in remission period. MethodsOne hundred and four patients with lumbar disc herniation in remission were randomly divided into a treatment group and a control group, with 52 cases in each group. Treatment group applied acupuncture with manipulation of pointing, pulling, and shaking. Acupoints were selected as lumbar Jiaji (EX-B2, bilateral), Ashi point, Shenshu (BL 23, bilateral), Huantiao (GB 30, bilateral), Weizhong (BL 40, opposite side of the affected area), Chengshan (BL 57, opposite side of the affected area). The control group applied lumbar traction plus acupoint ultrasonic pulse penetration therapy (acupoints selection same as the treatment group); 20 minutes each time, 3 times a week, a total of 3 weeks for both groups. The primary outcome was the improvement rate of lumbar disc herniation symptoms and signs, which was calculated at 1 week of treatment, 3 weeks of treatment, 1 month follow-up, and 3 months follow-up, respectively; the secondary outcome were the Japanese Orthopaedic Association (JOA) scores, Visual Analogue Scale (VAS) scores, and Oswestry Disability Index (ODI) scores (including ODI total scores, sitting scores and standing scores), which were evaluated before treatment, 1 week of treatment, 3 weeks of treatment, 1 month follow-up, and 3 months follow-up; clinical effectiveness was assessed at 3 months follow-up; and the occurrence of adverse events in the participants, as well as blood routine, urine routine, stool routine, and electrocardiograms before and after the treatment were recorded to evaluate safety. ResultsTwo patients from each group fell out, and 50 patients of each group were included in the outcome analysis ultimately. The scores of lumbar disc herniation symptoms and signs improved more in the treatment group than in the control group at 1 week of treatment, 3 weeks of treatment, 1 month follow-up and 3 months follow-up (P<0.01). The JOA scores of participants in both groups at 1 week of treatment, 3 weeks of treatment, 1 month follow-up and 3 months follow-up were higher than those before treatment in the same group, and the VAS scores, ODI total scores, ODI sitting scores and standing scores were significantly lower than those before treatment in the same group (P<0.05), and the JOA scores of patients in the treatment group were higher than those of the control group at all time points, and the VAS scores, ODI total scores, ODI sitting scores and standing score were lower than those of the control group (P<0.05). At the 3 months follow-up, the excellent rate of the treatment group was 70.00% (35/50) better than that of the control group, which was 50.00% (25/50) (P<0.05). There were no abnormalities in blood, urine, stool routines and electrocardiograms before and after treatment in both groups, and no adverse events occurred. ConclusionAcupuncture with manipulation of pointing, pulling, and shaking for treating patients with lumbar disc herniation in remission has a better safety on pain relief and improving quality of life, and the effectiveness is better than lumbar traction plus acupoint ultrasonic pulse penetration therapy.
