Efficacy evaluation of Mongolian medical warm acupuncture for sciatica caused by lumbar disc herniation: a randomized, controlled, single-blind clinical trial.

OBJECTIVE: This study aimed to evaluate the short-term and long-term efficacy of Mongolian medical warm acupuncture for sciatica caused by lumbar disc herniation (LDH). PATIENTS AND METHODS: The patients diagnosed with sciatica caused by LDH were randomly divided into the warm acupuncture of the Mongolian medicine group (n = 42, warm acupuncture treatment), the sham acupuncture group (n = 38, sham acupuncture using blunt-tipped needles) and the conventional drug group (n = 40, ibuprofen sustained release capsule). All patients were treated for 4 weeks and followed up for 8 weeks. The visual analog scale for leg pain (VAS-LP), Mongolian medicine indicators (efficacy indicators), VAS for waist pain (VAS-WP) and the Mos 36-item short form health survey (SF-36) score were analyzed at baseline, after two-week treatment, after four-week treatment, at four-week follow-up and at eight-week follow-up. RESULTS: Warm acupuncture treatment significantly decreased the VAS-LP and VAS-WP scores of patients at treatment and follow-up (p < 0.05), and pain was improved compared to the conventional drug group and sham acupuncture group. The total effective rate was markedly higher in the warm acupuncture of the Mongolian medicine group compared with the conventional drug group at 8-week follow-up (p < 0.05), but sham acupuncture treatment resulted in no evident improvement in the Mongolian medicine indicators. Additionally, at treatment and follow-up, warm acupuncture of the Mongolian medicine group showed a significant increase in the physical function, physical role, body pain, and emotional and mental health role scores of the SF-36 survey compared with the sham acupuncture groups. CONCLUSIONS: Mongolian medical warm acupuncture effectively relieves leg and waist pain and improves the total therapeutic effect and the quality of daily life for patients with sciatica caused by LDH, with significant long-term efficacy. Our study provides a basis for warm acupuncture in the treatment of sciatica caused by LDH. Chinese Clinical Trial Registry ID: ChiCTR- INR-15007413.

Efficacy of Individualized Homeopathic Medicines in the Treatment of Sciatica Pain: Double-Blind, Randomized, Placebo-Controlled Trial.

Objectives: Sciatica is a debilitating condition that causes pain in its distribution or in the lumbosacral nerve root that is connected to it. Although there are claims that homeopathy can reduce sciatica pain, systematic scientific proof is currently lacking. The objective of the trial was to determine whether individualized homeopathic medicines (IHMs) were as effective as identical-looking placebos in treating sciatica pain. Design: This is a double-blind, randomized (1:1), two parallel arms, placebo-controlled trial. Setting: The study was conducted at Mahesh Bhattacharyya Homoeopathic Medical College and Hospital, Howrah, West Bengal, India. Subjects: Sixty participants with sciatica pain were included in this study. Interventions: Verum (n = 30; IHMs plus concomitant care) versus control (n = 30; placebos plus concomitant care). Outcome measures: Primary-Sciatica Bothersome Index (SBI) and Sciatica Frequency Index (SFI) scores and secondary-Roland Morris Pain and Disability Questionnaire (RMPDQ), Short Form McGill Pain Questionnaire (SF-MPQ), and Oswestry Low Back Pain Questionnaire (OLBPQ) scores: all of them were measured at baseline, and every month, up to 3 months. Results: Intention-to-treat sample (n = 60) was analyzed. Group differences were examined by two-way (split-half) repeated measure analysis of variance, primarily accounting for between groups and time interactions, and additionally, by unpaired t tests comparing the estimates obtained individually every month. The level of significance was set at p < 0.025 and <0.05 two tailed for the primary and secondary outcomes, respectively. Group differences could not achieve significance in SBI (p = 0.044), SFI (p = 0.080), and RMPDQ scores (p = 0.134), but were significant for SF-MPQ (p = 0.007) and OLBPQ (p = 0.036). Gnaphalium polycephalum (n = 6; 10%) was the most frequently prescribed medicine. No harm, serious adverse events, or intercurrent illnesses were recorded in either of the groups. Conclusions: The primary outcome failed to demonstrate evidently that homeopathy was effective beyond placebo, and the trial remained inconclusive. Independent replications are warranted to confirm the findings. Clinical Trial Registration Number: CTRI/2020/10/028617.

Mitigation of sciatica injury-induced neuropathic pain through active metabolites derived from medicinal plants.

Sciatica characterized by irritation, inflammation, and compression of the lower back nerve, is considered one of the most common back ailments globally. Currently, the therapeutic regimens for sciatica are experiencing a paradigm shift from the conventional pharmacological approach toward exploring potent phytochemicals from medicinal plants. There is a dire need to identify novel phytochemicals with anti-neuropathic potential. This review aimed to identify the potent phytochemicals from diverse medicinal plants capable of alleviating neuropathic pain associated with sciatica. This review describes the pathophysiology of sciatic nerve pain, its cellular mechanisms, and the pharmacological potential of various plants and phytochemicals using animal-based models of sciatic nerve injury-induced pain. Extensive searches across databases such as Medline, PubMed, Web of Science, Scopus, ScienceDirect, and Google Scholar were conducted. The findings highlights 39 families including Lamiaceae, Asteraceae, Fabaceae, and Apocyanaceae and Cucurbitaceae, effectively treating sciatic nerve injury-induced pain. Flavonoids made up 53% constituents, phenols and terpenoids made up 15%, alkaloids made up 13%, and glycosides made up 6% to be used in neuorpathic pain. Phytochemicals derived from various medicinal plants can serve as potential therapeutic targets for both acute and chronic sciatic injury-induced neuropathic pain.

Combined Rehabilitation with Alpha Lipoic Acid, Acetyl-L-Carnitine, Resveratrol, and Cholecalciferolin Discogenic Sciatica in Young People: A Randomized Clinical Trial.

Background and Objectives: In the Western world, back pain and sciatica are among the main causes of disability and absence from work with significant personal, social, and economic costs. This prospective observational study aims to evaluate the effectiveness of a rehabilitation program combined with the administration of Alpha Lipoic Acid, Acetyl-L-Carnitine, Resveratrol, and Cholecalciferol in the treatment of sciatica due to herniated discs in young patients in terms of pain resolution, postural alterations, taking painkillers, and quality of life. Materials and Methods: A prospective observational study was conducted on 128 patients with sciatica. We divided the sample into 3 groups: the Combo group, which received a combination of rehabilitation protocol and daily therapy with 600 mg Alpha Lipoic Acid, 1000 mg Acetyl-L-Carnitine, 50 mg Resveratrol, and 800 UI Cholecalciferol for 30 days; the Reha group, which received only a rehabilitation protocol; and the Supplement group, which received only oral supplementation with 600 mg Alpha Lipoic Acid, 1000 mg Acetyl-L-Carnitine, 50 mg Resveratrol, and 800 UI Cholecalciferol. Clinical assessments were made at the time of recruitment (T0), 30 days after the start of treatment (T1), and 60 days after the end of treatment (T2). The rating scales were as follows: the Numeric Rating Scale (NRS); the Oswestry Disability Questionnaire (ODQ); and the 36-item Short Form Health Survey (SF-36). All patients also underwent an instrumental stabilometric evaluation. Results: At T1, the Combo group showed statistically superior results compared to the other groups for pain (p < 0.05), disability (p < 0.05), and quality of life (p < 0.05). At T2, the Combo group showed statistically superior results compared to the other groups only for pain (p < 0.05) and quality of life (p < 0.05). From the analysis of the stabilometric evaluation data, we only observed a statistically significant improvement at T2 in the Combo group for the average X (p < 0.05) compared to the other groups. Conclusions: The combined treatment of rehabilitation and supplements with anti-inflammatory, pain-relieving, and antioxidant action is effective in the treatment of sciatica and can be useful in improving postural stability.

A systematic review of conservative and surgical treatments for deep gluteal syndrome.

BACKGROUND AND OBJECTIVE: Conservative and surgical treatments, are recommended as the primary treatment in the management of patients diagnosed with deep gluteal syndrome; but evidence supporting superiority of one treatment over another is lacking. The aim of this review is to systematically review the effectiveness of treatments. DATABASES AND DATA TREATMENT: MEDLINE, EMBASE, Web of Science, Scopus, AMED, Cochrane Library (Central Register of Controlled Trials), and PEDro were screened (to 24 July 2019). Risk of bias of trials and surgical case series were assessed using the Cochrane risk of bias tool and Joanna Briggs Institute Critical appraisal checklists, respectively. Outcomes were reductions in pain or disability. For each outcome, the minimum clinically important difference (MCID) was calculated. A narrative synthesis was performed. RESULTS: Out of 909 records, thirteen studies with 508 patients were included, eight RCTs with 336 patients and 5 case series with 172 patients. Conservative modalities were: infiltration into muscle of steroid, botulinum toxin, thiochilcoside and colchicine. There was one RCT and five case series of surgery. Only three trials reached an MCID in pain reduction for the intervention. The five surgical studies reached a before and after MCID. Only one study showed an MCID reduction in disability. The overall quality of evidence was low. CONCLUSION: Given the low quality of evidence, no single conservative treatment can be recommended over another. Clinicians should follow general guidelines on the management of back pain and sciatica for first line treatment, namely physiotherapy. Surgery may have a place for chronic cases.

Role and anti-inflammatory mechanisms of acupuncture and moxibustion therapy on pain relief through NOX-ROS-NLRP3 pathway in CCI rats models.

OBJECTIVE: To observe the effects of acupuncture and moxibustion therapy on pain relief in sciatica rats and to explore the mechanism of its anti-inflammatory effect. METHODS: SPF grade 4-6-week-old Kunming rats were randomly divided into 5 groups including a blank group, sham-operated group, model group, acupuncture, and moxibustion (AnM) group, and positive group. A total of 10 rats were included in each group. The model group, the AnM group, and the positive group were prepared by ligating the left sciatic nerve. AnM group was used for acupuncture and moxibustion therapy intervention, and the positive group was rendered to quick-acting sciatica pills once a day for 7 days (3 courses of treatment). The blank group, sham-operated group, and model group were not treated. The changes in thermal and mechanical pain thresholds were observed before and after the operation, and the morphological changes of the dorsal horn of the spinal cord in the lumbosacral region of the rats in each group were observed by HE staining after the courses of treatment finished. The contents of IL-1ß, IL-6, IL-18, and TNF-α were measured by ELISA and the expressions of NOX1, NOX2, NOX4, and NLRP3 genes were detected by RT-qPCR while the protein expressions of NOX1, NOX2, NOX4 and NLRP3 were analyzed by Western blotting. RESULTS: The AnM and positive group showed a significant increase in thermal and mechanical pain thresholds after treatment, while there was no significant change in the model group. As compared to the control group, the contents of IL- 1ß, IL-6, IL-18, and TNF-α, as well as the relative expressions of NOX1, NOX2, NOX4, and NLRP3 genes were significantly increased in the model group (P < 0.05 or P < 0.01). As compared to the model group, the contents of IL-1ß, IL-6, IL-18, and TNF-α, as well as the relative expressions of NOX1, NOX2, NOX4, and NLRP3 genes significantly decreased in the AnM and positive groups (P < 0.05 or P < 0.01). The pathological changes of inflammatory infiltration of tissue cells in the dorsal horn of the lumbosacral spinal cord were slowed in the AnM group. CONCLUSION: Acupuncture and moxibustion therapy have a positive effect on pain relief and anti-inflammatory effects in CCI sciatica rats, which may point to the regulation of NOX1, NOX2, NOX4, and NLRP3 expressions, and inhibition of ROS.

Outcome measures included post-treatment pain and clinical efficacy. Results: Canggui Tanxue Technique demonstrated significant pain reduction and improved functional restoration compared to the routine technique, as evidenced by significantly lower scores on the Visual Analogue Scale (VAS), Japanese Orthopaedic Association (JOA) scores, and Roland-Morris Disability Questionnaire (RDQ) scores (P < .05). Patients receiving acupuncture with Canggui Tanxue Technique exhibited significantly higher clinical efficacy compared to those receiving the routine technique (P < .05). Conclusion: Acupuncture with Canggui Tanxue Technique on the Huantiao point provides superior pain reduction and functional restoration for patients with sciatica caused by lumbar disc herniation compared to routine techniques. This approach offers high safety, potent efficiency, and better operability.

[Intervention effect of Tuina pressing and kneading the Huantiao (GB30) acupoint on NF-κB p65 protein at spinal cord dorsal horn in sciatica rats].

OBJECTIVE: To observe the analgesic effect of Tuina by pressing and kneading the Huantiao (GB30) acupoint on rats with chronic constriction injury (CCI) and to explore the analgesic mechanism of Tuina on sciatica rats. METHODS: Thirty-two SPF male SD rats weighing 180 to 220 g were randomly divided into fore groups:blank group (without any treatment), sham group (only exposed without sciatic nerve ligating), model group (sciatic nerve ligating) and Tuina group (manual intervention after lsciatic nerve ligating). The CCI model was prepared by ligating the right sciatic nerve of the rats, on the third day of modeling, the rats in the Tuina group were given pressing and kneading the Huantiao (GB30) point for 14 days, and the changes of paw withdrawal threshold(PWT), paw withdrawal latency(PWL) were measured before and on the 1st, 3rd, 7th, 10th, 14th and 17th days after modeling. The changes of sciatic functional index(SFI) were measured before and on the 1st and 17th day after modeling. The morphological changes of the sciatic nerve were observed by hematoxylin-eosin(HE) staining;and the differences in NF-κB protein expression in the right dorsal horn of the spinal cord of rats were detected. RESULTS: Following modeling, there was no significant difference in PWT, PWL and SFI between the blank group and the sham group (P>0.05), but the PWT, PWL and SFI of the model group and the Tuina group decreased significantly (P<0.01). After manual intervention, the pain threshold of rats in Tuina group increased. On the 8th day of manual intervention (the 10th day after modeling), PWT in Tuina group increased significantly compared with that in model group (P<0.01). On the 5th day of manual intervention (the 7th day after modeling), the PWL of the massage group was significantly higher than that of the model group (P<0.01). The pain threshold of rats in Tuina group continued to rise with the continuous manipulation intervention. After 14 days of manipulative intervention, the sciatic nerve function index of rats in the Tuina group increased significantly(P<0.01). Compared with the blank group and sham group, the myelinated nerve fibers of sciatic nerve in the model group were disordered and the density of axons and myelin sheath was uneven. Compared with the model group, the nerve fibers of rats in the Tuina group were gradually continuous and the axons and myelin sheath were more uniform than those in the model group. Compared with the blank group and sham group, the expression of NF-κB protein in the right spinal dorsal horn of the model group was significantly increased(P<0.01). Compared with the model group, the expression of NF-κB protein in the right spinal dorsal horn of rats in Tuina group decreased significantly(P<0.01). CONCLUSION: Pressing and kneading the Huantiao (GB30) point restores nerve fiber alignment;and improves the PWT、PWL and SFI in the CCI model by decreasing NF-κB p65 protein expression in the spinal dorsal horn. There fore, Tuina demmstrates an analgesic effect and improves the gait of rats with sciatica.

The effect of a topical formulation from Lawsonia inermis L. (henna) on pain intensity in patients with chronic sciatica: A randomized double-blind clinical trial.

ETHNOPHARMACOLOGICAL RELEVANCE: Chronic sciatica (CS) is a common condition of disability and pain. Lawsonia inermis L. (henna) is a medicinal plant that is commonly recommended in traditional Persian medicine textbooks for pain relief in patients with sciatica, particularly in the form of oil. AIM OF THE STUDY: This research was designed to investigate the efficacy of a topical formulation from henna on pain intensity in patients with CS. METHODS AND MATERIALS: In a randomized, double-blind clinical study, 81 patients were randomly allocated to three groups to receive the topical henna formulation (aqueous extract of henna in sesame oil), sesame oil, or placebo, three times daily, for four weeks. The patients were assessed by visual analog scale (VAS), 36-item short form health survey (SF-36), and Oswestry disability index (ODI). RESULTS: There was a significant decrease in mean VAS in henna oil compared to sesame oil (p = 0.004) and placebo (p = 0.004). Significant improvements in total SF-36 scores were observed in henna oil and sesame oil compared to placebo (p = 0.011 and p = 0.025, respectively). Furthermore, ODI significantly decreased in henna oil compared to sesame oil (p < 0.001) and placebo (p = 0.005). CONCLUSION: Henna oil seems to be an effective treatment to reduce pain intensity in patients with CS. Moreover, it improves quality of life and functional ability. Further randomized controlled trials with longer intervention periods are recommended to confirm this efficacy.

BACKGROUND: There are more and more clinical studies on the efficacy of warm acupuncture in treating sciatica, but the systematic review of the efficacy of warm acupuncture is still lacking. The objective of this study was to evaluate the efficacy and safety of warm acupuncture combined with conventional Western medicine in the treatment of sciatica. METHODS: The review was registered in the PROSPERO database (CRD42022379486) and was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. The following databases will be used to search the existing literature (from inception to January 2023): Web of Science, Embase, Cochrane Library, PubMed, Cumulative Index to Nursing and Allied Health Literature, Wanfang, Allied and Complementary Medicine Database, China Knowledge Network, and SPORT-Discus. Included studies are considered eligible if they met the population, intervention, comparator, outcomes, and study design criteria as follows: Population: patients with newly diagnosed sciatica; Intervention: warm acupuncture combined with conventional Western medicine; Comparator: Western medicine alone; Outcomes: total response rate, pain score and pain threshold, adverse events and recurrence rate. Study design: randomized controlled trials or non-randomized cohort studies. Review Manager (RevMan) V.5.3 will be used to perform statistical analyses and to generate forest plots. RESULTS: The review will add to the existing literature by showing compelling evidence and improved guidance in clinic settings.

α-Asarone attenuates chronic sciatica by inhibiting peripheral sensitization and promoting neural repair.

This study explored the therapeutic effect of α-asarone on chronic sciatica. Thirty-two Sprague-Dawley (SD) rats were divided into four groups: the sham group, chronic constriction injury (CCI) group, pregabalin group, and α-asarone group. Hot hyperalgesia was induced after the CCI operation, and α-asarone was found to relieve chronic neuralgia. Furthermore, α-asarone reduced IL1ß, IL6, TNF-α, CRP, and LPS levels and increased IL10 levels in serum. α-Asarone decreased the protein levels of TRPA1, TRPM8, and TRPV1-4 and the mRNA levels of TRPA1, TRPM8, TRPV1-4, IL1ß, and TNF-α in dorsal root ganglion neurons. In the sciatic nerve, α-asarone treatment reduced the number of inflammatory cells and promoted the proliferation of Schwann cells, favouring recovery of the nerve structure. In cellular experiments, LPS induced Schwann cell apoptosis via TLR4/p38MAPK signalling; α-asarone attenuated LPS-induced Schwann cell apoptosis by decreasing TLR4, p-p38MAPK, cleaved-caspase3, and cleaved-caspase7 levels and increasing Bcl-2 and Bcl-xl expression. Overall, these findings suggest that α-asarone relieves chronic sciatica by decreasing the levels of inflammatory factors, inhibiting peripheral sensitization, and favouring the repair of damaged nerves.

Cascade of decisions meet personal preferences in sciatica treatment decisions.

STUDY DESIGN: An in-depth interview study including patients, general practitioners, neurologists and neurosurgeons. OBJECTIVE: To gain insight in decision-making in sciatica care, by identifying patients' and physicians' preferences for treatment options, and the differences between and within both groups. SUMMARY OF BACKGROUND DATA: Sciatica is a self-limiting condition, which can be treated both conservatively and surgically. The value of both options has been disputed, and the care pathway is known for a substantial amount of practice variation. Most Dutch patients are taken care of by general practitioners before they are referred to hospital-based neurologists, who might refer to a neurosurgeon, who can perform a surgical intervention. Dutch sciatica care thus follows the principles of stepped care, and a cascade of decisions precedes surgery. Better understanding of the decision-making within this cascade might reveal opportunities to improve shared decision-making and to reduce unwarranted practice variation. METHODS: Interviews with 10 patients and 22 physicians were analysed thematically. RESULTS: While physicians were confident of their clinical diagnosis, patients preferred confirmation trough imaging to exclude other possible explanations. Furthermore, many patients showed reluctance towards the use of (strong) opioids, while all physicians favoured this and underlined the benefits of opioids in the management of sciatica complaints, to buy time and to allow patients to recover naturally. Finally, individual physicians differed strongly in their opinion on benefits and optimal timing of surgical treatment and epidural injections. CONCLUSIONS: Dutch sciatica care is characterised by a cascade of decisions preceding surgery. Preferences differ within and between patients and physicians, which adds to the practice variation. To improve decision-making, physicians and patients should invest not necessarily more in the exchange of options or preferences, but in making sure the other understands the rationale behind them.

Ischial osteochondroma as an unusual source of pregnancy-related sciatic pain: a case report.

BACKGROUND: While most cases of sciatica result from degenerative conditions of the low back, some cases result from conditions of the hip and pelvic region. Sciatica developing in relation to pregnancy or labor also presents unique considerations. CASE PRESENTATION: A 37-year-old African American woman with a history of hypertension and polycystic ovary syndrome presented to a chiropractor at a hospital-based outpatient clinic with a seven-week history of low back pain with radiation into the right lower extremity which began during labor. The chiropractor performed a brief trial of care, yet when the patient's symptoms worsened, ordered lumbar spine radiographs, followed by lumbar magnetic resonance imaging (MRI), which were both normal. The chiropractor then ordered hip radiographs, which were suggestive of ischial osteochondroma, and referred the patient to an orthopedic oncologist. MRI findings were compatible with an osteochondroma with associated adventitial bursitis and mass effect on the sciatic nerve. The patient initially chose conservative management with bursa aspiration and therapeutic injection. Despite initial relief, there was eventual return of symptoms. The patient elected to undergo surgical removal, with a positive outcome. CONCLUSION: The key distinguishing features that led to a diagnosis of osteochondroma in this case included attention to the patient-reported symptoms and history, worsening of symptoms despite conservative care, and lack of explanatory findings on lumbar imaging. This case highlights the benefit of evaluating the hip and pelvis when the clinical features of sciatica cannot be ascribed to a lumbar etiology. This case also illustrates the role of a chiropractor working in an integrative health system to facilitate timely imaging and referrals to resolve a challenging diagnosis.

Dexamethasone-Loaded Injectable In-situ Thermal Crosslinking Magnetic Responsive Hydrogel for the Physiochemical Stimulation of Acupoint to Suppress Pain in Sciatica Rats.

The physicochemical stimulation of acupoints is a widespread treatment strategy for different diseases, such as sciatica. Its efficacy is mainly based on the temporal and spatial modulation of the physicochemical properties of the acupoints. The existing therapies based on the stimulation of acupoints have certain disadvantages. Therefore, in this study, injectable dexamethasone (DXM)- and magnetic Fe3O4 nanoparticles-loaded chitosan/ß-glycerophosphate (CS/GP) thermal crosslinking hydrogels were prepared, thereby improving the performance of embedding materials. The sciatica rat models were established to compare the therapeutic effects of hydrogels and catgut. The DXM or Fe3O4-loaded CS/GP hydrogels were compared in terms of their gelation kinetics, release kinetics, magnetic responsiveness in-vitro, and biocompatibility as well as their analgesic effects on the chronic constriction injury of the sciatic nerve (CCI) rats in-vivo. The CS/GP/Fe3O4/DXM hydrogel showed comparable gelation kinetics and good magnetic responsiveness in-vitro. This hydrogel could relieve sciatica by reducing the expression levels of inflammatory factors in serum, inhibiting the p38MAPK (p38, mitogen-activated protein kinase) phosphorylation, and decreasing the expression level of the P2X4 receptor (P2X4R) in the spinal dorsal horn. In conclusion, the DXM or Fe3O4-loaded CS/GP hydrogels can be considered as a treatment option for the physiochemical stimulation therapy of acupoints to improve sciatica.

Ferulic acid alleviates sciatica by inhibiting peripheral sensitization through the RhoA/p38MAPK signalling pathway.

BACKGROUND: Nonsteroidal anti-inflammatory drugs are used to relieve sciatica, but their effects are not satisfactory. PURPOSE: This study aimed to explore the therapeutic effects of ferulic acid on sciatica. METHODS: Thirty-two SD rats were randomly divided into 4 groups, i.e., sham operation group, chronic constriction injury (CCI) group, mecobalamin group, and ferulic acid group. We conducted behavioural tests, ELISA, PCR, Western blots, and immunofluorescence analysis. Specific inhibitors were used in cell experiments to explore the related mechanisms. RESULTS: Thermal hyperalgesia was induced after CCI operation, and ferulic acid relieved thermal hyperalgesia. In addition, ferulic acid decreased the IL1ß, IL6, TNF-α, and CRP mRNA levels; the IBA-1, iNOS, IL1ß, RhoA, RhoA-GTP, COX2, Rock1, TRPV1, TRPA1, and p-p38MAPK levels in dorsal root ganglion (DRG) neurons; and the LPS, CRP, substance P (SP), and prostaglandin E2 (PGE2) levels in serum, and these levels were higher in the CCI group. In the cell experiments, LPS induced M1 polarization of GMI-R1 cells via the RhoA/Rock pathway. Ferulic acid attenuated LPS-induced M1 polarization by decreasing the levels of M1 polarization markers, including IL1ß, IL6, TNF-α, iNOS, and CD32, and increased M2 polarization by increasing the levels of M2 polarization markers, including CD206 and Arg-1. LPS treatment clearly increased the iNOS, IL1ß, RhoA, Rock1, Rock2 and p-p38 MAPK levels and reduced Arg-1 expression, and ferulic acid reversed these changes. CONCLUSION: Ferulic acid can inhibit peripheral sensitization by reducing the levels of inflammatory factors, TRPA1 and TRPV1 through the RhoA/p38 MAPK pathway to alleviate sciatica.

The effectiveness and safety of acupuncture treatment on sciatica: A systematic review and meta-analysis.

BACKGROUND: Sciatica results from primary or secondary damage to the sciatic nerve in the lumbar or gluteal region. The first option for sciatica is analgesics, but their therapeutic effect and safety in long-term use are questionable. On the other hand, acupuncture has recently been recognized as a complementary and alternative medicine (CAM) to conventional medicine, and studies on its effectiveness and safety have been actively conducted. OBJECTIVE: To systematically compare acupuncture with analgesics in terms of effect, safety, and durability in the treatment of sciatica METHODS: This review was performed in accordance with Cochrane Handbook for Systematic Reviews of Interventions Version 6.2. Four databases were searched for this review: Wangfang, the Korean Traditional Knowledge Portal (KTKP), PubMed, and EBSCOhost. The primary outcome measures in the review were total effective rate (TER), visual analog scale (VAS) score and pain threshold, and the secondary ones were adverse effects (AEs) and relapse rates. Risk ratio (RR) for TER and mean difference (MD) for VAS score and pain threshold were used as statistics for the meta-analysis of effectiveness, along with associated 95 % confidence intervals (CIs) and P-values. AEs and relapse rates were used for the safety and durability of the interventions. Version 2 of the Cochrane risk-of-bias assessment tool for randomized trials (RoB 2) was used for the methodological quality of randomized controlled trials (RCTs) included in the review. RESULTS: The synthesized TER of 28 RCTs involving 2707 participants was significantly higher in the acupuncture group compared to the analgesic group (RR [95 % CI] = 1.20 [1.16, 1.24], P < 0.001). The synthesized VAS score of 7 RCTs involving 589 participants was significantly reduced in the acupuncture group compared to the analgesic group (MD [95 % CI] = - 1.78 [- 2.44, - 1.12], P < 0.001). In 5 RCTs involving 311 participants, the synthesized pain threshold was significantly elevated in the acupuncture group compared to the analgesic group (MD [95 % CI] = 0.93 [0.64, 1.22], P < 0.001). Additionally, adverse effects (AEs) and relapse rates of RCTs in the review were lower in the acupuncture group compared to the analgesic group. CONCLUSION: In this systematic review, acupuncture treatment was significantly effective and safe compared to analgesics in sciatica. In the future, studies with a rigorous study design are required to increase the validity of the effectiveness and safety of acupuncture treatment for sciatica.

Ma's bamboo-based medicinal moxibustion therapy of low back pain in lumbar disc herniation: study protocol for a randomized controlled trial.

BACKGROUND: Lumbar disc herniation (LDH) is a common and frequently occurring disease in clinics. Low back pain and sciatica are the presenting symptoms of LDH. To some extent, it can be considered that measures with the capability to improve low back pain or sciatica have the potential to treat LDH. Ma's bamboo-based medicinal moxibustion therapy can effectively reduce the degree of low back pain and has been widely used. Studies of small sample size have seen significant improvement on pain relief. The aim of this trial is to evaluate the clinical efficacy and safety of Ma's bamboo-based medicinal moxibustion therapy in the treatment of LDH low back pain. METHODS/DESIGN: The trial is a multicenter, randomized, parallel-group, non-inferiority study. Three hundred and twelve patients will be randomly assigned to a Ma's bamboo-based medicinal moxibustion group (n=156) and an acupuncture group (n=156). Patients in each group will receive treatment every day, 6 times a week, 12 times in total. Follow-up will be conducted 14 days after treatment. The primary outcome will be the visual analog scale(VAS) at baseline, after 6 times of treatment, end of treatment, and follow-up. The secondary outcomes will include Oswestry disability indexes (ODI), modified Japanese Orthopaedic Association low back pain (M-JOA) score, serum ß-endorphin (ß-EP), and serum substance P (SP). ß-EP and SP, as well as safety evaluation indexes (routine blood, liver, and kidney function and electrocardiogram), will be measure at baseline and after the end of treatment. The number, nature, and severity of adverse events will be recorded. DISCUSSION: The results of the trial will compare the efficacy of low back pain in LDH between Ma's bamboo-based medicinal moxibustion group and the acupuncture group and will be expected to make a systematic and objective evaluation of the clinical efficacy and safety of Ma's bamboo-based medicinal moxibustion therapy.

Pediatric lumbar disc herniation: a report of two cases and review of the literature.

BACKGROUND: Lumbar disc herniation (LDH) is not a common condition in children. Most reports on pediatric LDH concern the outcomes of surgeries performed in children in whom nonsurgical treatment failed while the outcome of nonsurgical treatment of LDH in children was rarely reported. CASES PRESENTATION: Case 1: a 10-year-old girl presented with back pain and sciatica in her left leg for over 3 months. The physical examination revealed exacerbation of back pain by waist extension or flexion, and a positive Lasegue's sign was revealed in her left leg. Magnetic resonance imaging (MRI) revealed lumbar disc herniation at the L5/S1 level. She was diagnosed with LDH. After receiving nonsurgical treatment of traditional Chinese medicine (TCM) for 30 days, the girl had mild low back pain and sciatica and the symptoms had resolved completely at the 3-month follow-up. There was no recurrence within the following 2 years. MRI performed 30 months later revealed that the herniated disc did not shrink significantly. However, she was totally asymptomatic at the follow-up performed 30 months later. Case 2: a 13-year-old boy presented with sciatica in his left leg for over 3 months. The physical examination revealed that Lasegue's sign was positive in the left leg, the level of muscle strength in the left ankle plantar flexors was grade 4. MRI revealed a lumbar disc herniation at the L5/S1 level. He was diagnosed with LDH. The boy underwent 2 weeks of TCM treatment, and exhibited a favorable outcome: only mild pain was noticed in his left buttocks after walking for more than 15 min. He was asymptomatic at the 3-month follow-up and there was no recurrence within the next 3 years. MRI scan performed at 40 months later showed no significant resorption of the herniated disc. However, he was totally asymptomatic at the follow-up performed 40 months later. CONCLUSIONS: For the nonsurgical treatment of pediatric LDH, resorption of herniated discs is not necessary for favorable long-term outcomes, and children with symptomatic LDH may become asymptomatic without resorption.

Effects of Fu's subcutaneous needling on mitochondrial structure and function in rats with sciatica.

To observe the effects of Fu's subcutaneous needling (FSN) and acupuncture treatment on the mitochondrial structure and function of the skeletal muscle tissue of rats with sciatica. Forty Sprague-Dawley rats were divided into control, model, acupuncture, and FSN groups (10 each) according to a random number table. The control group was left untreated. Rats in the FSN group were treated with FSN once every 2 days for three times, respectively (days 1, 3, 5, and 7), to cooperate with reperfusion approach. The acupuncture group was treated at the same timeline as that of the FSN group. Changes in the mechanical pain threshold, mitochondrial ultrastructure, mitochondrial citrate synthase (CS) activities, mitochondrial respiratory chain complex II, and mitochondrial COX- I protein expression in the skeletal muscle of rats treated with different treatments were compared with those of the model group. The pain thresholds of the rats were remarkably higher after FSN treatment and acupuncture, and the pain threshold of the FSN group was higher than that of the acupuncture group. Compared with the control group, the mitochondria of the model group had a damaged ultrastructure, were arranged in a disorganized manner, accumulated under the basement membrane, and appeared vacuolated with autophagosomes. The state of mitochondria in the FSN group was close to that in the control group and was remarkably better than that in the acupuncture group. The activities of mitochondrial CS and respiratory chain complex II in the skeletal muscle of the treated rats decreased compared with the control group (p < 0.05), and their levels were better in the FSN group than in the acupuncture group (p < 0.05). FSN treatment for 1 week considerably improved the pain thresholds and improved the skeletal muscle mitochondrial ultrastructure and mitochondrial function in rats with sciatica.
