Objective:A meta-analysis was performed to evaluate the difference of curative effect of Huoxue huayu Chinese medicine compound combined with intervertebral pore lens in the treatment of lumbar disc herniation.Methods:CNKI,VIP,CBM,PubMed and Web of Science were searched by computer and included in the clinical trial data about the treatment of lumbar disc herniation by the Huoxue huayu Chinese medicine compound and intervertebral pore lens.Data were extracted and Cochrane system was used to evaluate the quality of the study.Cochrane system in ReMan 5.1 was used to evaluate the publication bias and Stata 12.0 was used for meta analysis.Results:A total of 1039 patients were included in 16 articles,including 519 patients in the treatment group and 520 patients in the control group.The results showed that the total effective rate of the treatment group was higher than that of the control group(RR=1.20,95%CI(1.11,1.30),P<0.05);The excellent rate of the treatment group was higher than that of the control group(RR=1.20,95%CI(1.08,1.32),P<0.05);The JOA score of the treatment group was higher than that of the control group(MD=3.39,95%CI(1.90,4.87),P<0.00001);the VAS score of the treatment group was lower than that of the control group(MD=-1.13,95%CI(-1.84,-0.42),P=0.002);The ODI score of the treatment group was lower than that of the control group[MD=-3.34,95%CI(-4.49,-2.19),P<0.00001].Conclusion:Huoxue huayu Chinese medicine compound and intervertebral pore lens can improve the clinical effect and is worth popularizing.However,due to the poor quality of the literature,more high-quality double-blind randomized controlled trials with large samples are needed.

Early efficacy of endoscopic translaminar and intervertebral foraminal approaches in the treatment of lumbar disc herniation

Objective:To investigate the early efficacy of two approaches for lumbar disc herniation under spinal endoscopy.Methods:45 cases of lumbar disc herniation were divided into interlaminar approach(27 cases)and intervertebral foramen approach(18 cases)according to different surgical approaches.Postoperative pain visual analogue scale(VAS)was used.Japanese Orthopaedic Association(JOA)lumbar spine score(JOA)and modified Macnab criteria were used to evaluate the postoperative outcome.Results:(1)VAS score.There is no interaction effect between the access mode and the time factor(F=0.620,P=0.603).There were statistically significant differences in pain VAS scores between preoperative and postoperative time points,that is,there was a time effect(F=2157.488,P=0.000).The overall VAS scores of the two groups were compared,and the difference was not statistically significant,that is,there was no grouping effect(F=2.610,P=0.114).The VAS score of pain in both groups decreased with time,and the differences between the two groups were not statistically significant before surgery,at discharge,1 month after surgery and 3 months after surgery(t=0.067,P=0.947;t=1.415,P=0.164;t=0.564,P=0.575;t=0.442,P=0.660);JOA score.There is no interaction effect between the access mode and the time factor(F=1.296,P=0.280).The difference of JOA score between preoperative and postoperative time points was statistically significant,that is,there was a time effect(F=1464.830,P=0.000).JOA scores of the two groups showed an increasing trend with time,and the differences between the two groups were not statistically significant before surgery,at discharge,1 month after surgery and 3 months after surgery(t=0.067,P=0.947;t=1.415,P=0.164;t=0.564,P=0.575;t=0.442,P=0.660);(2)The improved Macnab standard was used to evaluate the excellent and good rate at 3 months after surgery.In the interlaminar group,12 cases were excellent,13 cases were good and 2 cases were fair.The excellent and good rate was 92.6%.In the intervertebral foramen group,7 cases were excellent,10 cases were good and 1 case was fair.The excellent and good rate was 94.4%.The overall excellent and good rate of the two groups was 93.3%.Conclusion:Both approaches can achieve satisfactory efficacy in the treatment of lumbar intervertebral disc herniation,which is worthy of clinical application.However,for beginners,l5-s1 lumbar disc herniation is more suitable for intervertebral disc approach,so as to achieve satisfactory efficacy.

Isolation of <i>Gemella morbillorum</i>in Herniated Intervertebral Disc Tissue in a Lumbar Discectomy Patient: A Case Report

Back pain associated with lumbar disc herniation is a common musculoskeletal disorder that leads to absence at work place worldwide. Studies have proven in addition to the traditional factors, microbes play a role in disc herniation causing chronic back pain. A 34-year-old male who has not involved in any traumatic work but has a family history of disc herniation presented with lower back pain and numbness in his right leg. He had previously undergone lumbar discectomy at L4/L5 ten years back. Magnetic Resonance Imaging (MRI) showed L5/S1 right para central disc herniation impinging on the right S1 and S2 nerve roots. Standard protocols for disinfection of instruments, external skin and all transport media were adhered. Skin scrapings, muscle biopsy and excised disc tissue were obtained for anaerobic and aerobic bacterial cultures. Anaerobic microbial cultures of excised disc tissue following lumbar discectomy showed Gram positive growth. Further anaerobic isolation carried out using RapID ANA ID kit confirmed the growth as Gemella morbillorum. In addition, neither of the control samples (muscle nor skin) had any anaerobic growth indicating the absence of contamination. Aerobic bacterial growth was not present in the skin, muscles and disc cultures. The study findings add to the available literature, on the role of microorganisms in lumbar disc herniation and future treatment regimens with antibiotics.

DISCUSSION OF MECHANISM ON LUMBAR DISC HERNIATION TREATED WITH BLOODLETTING ON W■IZH■NG(委中BL40)

Objective To observe the changes of sciatic nerve conduction velocity （SNCV） and interleukin-1α （IL-1α）, phospholipase A2 （PLA2） and prostaglandin E2 （PGE2） in neucleus pulposus tissue in experimental rabbits with lumbar disc herniation （LDH） ; and discuss the mechanism of LDH treated with bloodletting on Wěizhōng （委中 BL40）. Methods 40 normal named control group, LDH model group, BL40 group New Zealand rabbits were randomized into 4 groups, and comparative point group. The experimental LDH model was prepared by the self-made LDH animal pathological modeling device. Bloodletting on BL40 or on comparative point was applied for 7 days. BL-410 physiological signal recorder was used to record SNCV. Enzyme-linked immunosorbent assay （ELISA） and radioimmunology methods were used to determine the contents of IL-1α and PLA2 in neucleus pulposus tissue and PGE2 in serum. Results In BL40 group, SNCV was significantly increased after treatment comparing with that before treatment （P〈0. 01 ）, and the difference in SNCV value before and after treatment was significantly bigger than that in model group and comparative point group （P〈0.05）. Bloodletting on BL40 reduced the contents of IL-1α and PLA2 in neucleus pulposus tissue and serum PGE2 in LDH rabbits, which indicated significant difference or very significant results in the comparison with model and comparative point groups （P〈0.01 or 0. 05）. Conclusion Bloodletting speeded up rapidly SNCV and reduced the contents of inflammatory factors, i.e. IL-1α, PLA2 and serum PGE2 in LDH rabbits, which indicated that alleviation of local inflammatory reaction is probably one of the mechanisms on LDH treated by bloodletting on BL40.

Apparent diffusion coefficient in normal and abnormal pattern of intervertebral lumbar discs: initial experience

The aim of the present study was to compare the relationship of morphologically defined non-bulging/herni-ated, bulging and herniated intervertebral lumbar discs with quantitative apparent diffusion coefficient （ADC）. Thirty-two healthy volunteers and 28 patients with back pain or sciatica were examined by MRI. All intervertebral lumbar discs from L1 to S1 were classified according to morphological abnormality and degenerated grades. The ADC values of nucleus pulposus （NP） were measured and recorded. The significant differences about mean ADC values of NP were found between non-bulging/herniated discs and bulging discs as well as herniated discs （P 0.05）, whereas there were no significant differences in ADC values between bulging and herniated discs （P 0.05）. Moreover, statistically significant relationship was found in the mean ADC values of NP between ＂non-bulging/herniated and non-degenerated discs＂ and ＂non-bulging/herniated degenerated discs＂ as well as herniated discs （P 0.05）. Linear regression analysis between ADC value and disc level revealed an inverse correlation （r = -0.18）. The ADC map of the NP is a potentially useful tool for the quantitative assessment of componential and molecular alterations accompanied with lumbar disc abnormalities.

Comparison of microendoscopic discectomy and open discectomy for single-segment lumbar disc herniation

BACKGROUND Lumbar disc herniation is a common disease.Endoscopic treatment may have more advantages than traditional surgery.AIM To compare the clinical efficacy and safety of microendoscopic discectomy(MED)and open discectomy with lamina nucleus enucleation in the treatment of singlesegment lumbar intervertebral disc herniation.METHODS Ninety-six patients who were operated at our hospital were selected for this study.Patients with single-segment lumbar disc herniation were admitted to the hospital from March 2018 to March 2019 and were randomly divided into the observation group and the control group with 48 cases in each group.The former group underwent lumbar discectomy and the latter underwent laparotomy and nucleus pulpectomy.Surgical effects were compared between the two groups.RESULTS In terms of surgical indicators,the observation group had a longer operation time,shorter postoperative bedtime and hospital stay,less intraoperative blood loss,and smaller incision length than the control group(P<0.05).The excellent recovery rate did not differ significantly between the observation group(93.75%)and the control group(91.67%).Visual analogue scale pain scores were significantly lower in the observation group than in the control group at 1 d,3 d,1 mo,and 6 mo after surgery(P<0.05).The incidence of complications was significantly lower in the observation group than in the control group(6.25%vs 22.92%,P<0.05).CONCLUSION Both MED and open discectomy can effectively improve single-segment lumbar disc herniation,but MED is associated with less trauma,less bleeding,and a lower incidence of complications.

Clinical Outcome of Percutaneous Endoscopic Lumbar Surgery (PELS) in Treatment of Lumbar Disc Herniation

Lumbar disc herniation is a spinal problem seen in both young and old people causing pain in the back with pain and numbness in lower extremity leading to disability limiting daily activities. When conservative treatments are ineffective, then it is treated by surgeries, more recently with minimal invasive percutaneous endoscopic lumbar surgery (PELS). One of the mostly accepted PELS by spinal surgeons is percutaneous transforaminal endoscopic lumbar discectomy, which can be performed for any age. The main aim of this review was to evaluate clinical outcome and safety based on the Oswestry Disable Index (ODI), Visual Analog Scale (VAS) and MacNab criteria and complications of PELS surgery and its advantages in clinical basis.

The Clinical Outcomes of Transforaminal Percutaneous Endoscopic Discectomy in Treating Lumbar Disc Herniation: A Review

Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive technique started during the late 20th century. This process is done through microscopic view under local anesthesia. There is a growing but still insufficient evidence that lumbar EDS shows slightly better results in terms of minor tissue damage, shorter hospital stay, faster return to ordinary daily activities, and patient satisfaction. Recurrence rate still remains a matter of debate, and is related with the surgical skills of the surgeon. The complication rate seems to be similar in both of the techniques i.e., open and endoscopic. More randomized controlled trials, systematic reviews and meta-analysis are needed to clarify whether lumbar EDS can be considered comparable if not superior to standard open discectomy. In spite of lacking defined clinical evidence, lumbar EDS is without doubt a rapidly expanding PELD and its future developments are incredibly promising. Due to less complication rate this technique can be considered as a gold standard compared to the open discectomy. The surgeons still require more cadaveric practices for learning the curve and to approach the herniated disc area. The main objective of this review article is to show the clinical outcomes of the Transforaminal Percutaneous Endoscopic Discectomy in treating the lumbar disc herniation.

Results The total scores of general symptoms after four months and seven months of treatment were 15.30±5.66 and 19.08±4.57 respectively, which were much higher than the score of 7.42±2.20 before the treatment （both P〈0.01 ）, in addition, the score after seven months of treatment was higher than that after four months of treatment. The variation of scores in patients with different types after treatment was statistically significant （P〈0.05）, and the best effect can he seen in the blood stagnation type of patients with herniation of hnnbar intervertebral disc, then less the patients with liver and kidney deficiency type. Conclusion Electroacupuneture plus waist-strengthening exercises has a satisfactory therapeutic effect on herniation of lumbar intervertebral diste, the longer course of treatment is, the beffer therapeutic effect achieved.

A Study on Extension－Flexion Dynamic Lumbar Spine Radiographsin Patients with Lumbar Intervertebral Disc Herniation

The study has collected a set of clinical materials such as extension-flexion dynamic lum-bar spine radiographs and computerized x-ray tornography of lumbar spine and quantified physical exami-nation from 32 patients with lumbar intervertebral disc herniation, who had gone through a suocessful con-servative treatment. The collection was conducted twice before and after the treatment. With the help oft-test and linear correlation analysis, the study suggests that extensionflexion radiograph of lumbar spineis of important clinical significance in weighing the clinical state of an individual patient, especially forthose who receive conservative treatment. The study emphasizes that the biomechanical disturbance oflumbar spinal column may be from another important pathological element along with the irritation of thenerve root by herniated disc tissue in the pathomechanics of lumbar disc herniation. There is also somediscussion of the computerized X-ray tomography diagnosis in this study. Above all, the author provides anew angle of viewing the trouble by one of the soul principles of traditional Chinese medicine: concept ofholistics .

Autologous nucleus pulposus transplantation to lumbar 5 dorsal root ganglion after epineurium discission in rats： a modified model of non-compressive lumbar herniated intervertebral disc

Background Nucleus pulposus of intervertebral discs has proinflammatory characteristics that play a key role in neuropathic pain in lumbar herniated intervertebral disc. One of the most commonly used animal models （the traditional model） of non-compressive lumbar herniated intervertebral disc is created by L4-L5 hemilaminectomy and the application of autologous nucleus pulposus to cover the left L4 and L5 nerve roots in rats. However, such procedures have the disadvantages of excessive trauma and low success rate. We proposed a modified model of non-compressive lumbar herniated intervertebral disc in which only the left L5 dorsal root ganglion is exposed and transplanted with autologous nucleus pulposus following incision of epineurium. We aimed to compare the modified model with the traditional one with regard to trauma and success rate. Methods Thirty Sprague-Dawley male rats were randomized into three groups： sham operation group （n=6）, traditional group （n=12）, and modified group （n=12）. The amount of blood loss and operative time for each group were analyzed. The paw withdrawal threshold of the left hind limb to mechanical stimuli and paw withdrawal latency to heat stimuli were examined from the day before surgery to day 35 after surgery. Results Compared with the traditional group, the modified group had shorter operative time, smaller amount of blood loss, and higher success rate （91.7% versus 58.3%, P 〈0.05）. There was no decrease in paw withdrawal latency in any group. The sham operation group had no decrease in postoperative paw withdrawal threshold, whereas the modified and traditional groups had significant reduction in paw withdrawal threshold after surgery （mechanical hyperalgesia）. Conclusions Transplantation of nucleus pulposus onto the L5 dorsal root ganglion following incision of epineurium in rats established an improved animal model of non-compressive lumbar herniated intervertebral disc with less trauma and more stable pain ethology.
