Kambin and Gellmann in 1973 in the United States and Hijikata in Japanin 1977 individually preformed posterolateral percutaneous nucleotomy for the resection of the nucleus pulposus and release of compressed exiting nerve root, which is now spreading through the world and many surgeons are developing their skill but it needs experience and patience for successful outcomes. Along with advanced instruments now the surgery can be performed only giving a small skin incision of 8 - 10 mm and is as effective as the conventional method of surgery and open microdiscectomy surgery for the treatment of symptomatic lumbar disc herniation. In this review, we are explaining the technique of minimally invasive Percutaneous Transforaminal Endoscopic Discectomy surgery along its advantages and complications which can be encountered while performing this technique.展开更多

In addition, the metabolic characteristics of LDH and ZKGC treatment were investigated with a liquid-chromatography with time-of-flight mass spectrometer (LC/Q-TOF-MS)-based metabolomics study. Nucleus pulpous tissues from rat models were collected and analyzed by metabolomics.[Results] By metabolism network analysis, lipid metabolism was up-regulated in LDH rat models and the treatment with ZKGC significantly reversed the abnormal up-regulated lipid metabolism. Meanwhile, the treatment of ZKGC also regulated the markers of neuron autophagy and inflammatory response in serum.[Conclusions] These results indicated that a complex mechanism, including abnormal lipid metabolism, associates with the progress of LDH, and multiple pathways might be involved in ZKGC s therapeutic effects on LDH.展开更多

Gua Sha was performed from the 5 th day after the surgery, once every other day, 3 times for a course of treatment,and totally 3 courses. The thermal withdrawal latency was evaluated using the intelligent hot plate one day before the surgery, and on days 4(the day before the treatment), 10(the end of the firstcourse), 16(the end of the second course) and 22(the end of the third course). On days 4, 10, 16 and22, six rats in each group were picked randomly and their blood samples were drawn to assess the expression of interleukin-1β(IL-1β), interleukin-6(IL-6) and tumor necrosis factor-alpha(TNF-α).RESULTS: Compared to rats in the sham group, the application of nucleus pulposus to right L5 dorsal root ganglion induced prolonged thermal hyperalgesia, and up-regulated the expression of IL-1β,IL-6 and TNF-α in serum(P < 0.01). The therapy of Gua Sha attenuated thermal hyperalgesia potently,inhibited the expression of IL-1β, IL-6 and TNF-α in a time-dependent manner(P < 0.01). There were no significant differences in the thermal withdrawal latency and the expression of inflammatory cytokines between the sham and Gua Sha groups at the end of the treatment(P > 0.01).CONCLUSION: The current study showed that Gua Sha might alleviate thermal hyperalgesia in rats with lumbar disc herniation induced by autologous nucleus pulposus via inhibiting the expression of proinflammatory cytokins.展开更多

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.展开更多
