地佐辛對(duì)糖尿病神經(jīng)病理性疼痛大鼠脊髓背角NMDA-2B受體表達(dá)的影響
[Abstract]:Objective: Diabetic peripheral neuropathy (DPN) pain is a type of neuropathic pain (NP), and DPN is one of the most common complications of diabetes. The morbidity of DPN is about 7.5% to 24%. The pathogenesis of DPN is very complicated. The central sensitization plays an important role in the production and maintenance of DPN, and the excitatory neurotransmitter glutamate and its receptor NMDA are involved in the occurrence of central sensitization. As a subunit of the NMDA receptor, NMDA-2B is especially important for the transmission of nociceptive signals. Therefore, the research on the NMDA receptor in recent years has been focused on the NMDA-2B subunit. As a novel and potent hybrid opioid receptor agonist-antagonist, Zorzin is characterized by strong analgesic effect and low adverse reaction, and has been widely used in clinic In this study, the effect of tramadol on DPN was found to be effective in the treatment of DPN, and the effect of DPN on DPN was not very clear. Type, and then give the ground Zusin to intervene. Changes in body weight, fasting blood glucose and 50% reduced foot response threshold (PWT) in three groups of rats were prepared by observing the normal group (Normal group), the diabetic neuropathic pain group (Control group), and the diabetic neuropathic pain model. Immunohistochemistry and RT-PCR were used to compare the expression of NMDA-2B receptor in the spinal dorsal horn of diabetic neuropathic pain rats. To study the effect of zocassin on the pain of diabetic patients with neuropathic pain and its potential role in the treatment of diabetic neuropathic pain Methods:80 healthy adult male SD rats, weighing 130 g ~ 150 g, were used in animal experiment of Hebei Medical University The model was prepared by randomly selecting 60 rats for intraperitoneal injection of STZ (50 mg/ kg). After a week of injection of STZ, the fasting blood glucose of 45 rats was 16.7 mol/ L (the success rate was 75%), and it was qualified. The PWT and PWT of the experimental rats were measured with von Frey Hairds two weeks after the injection of STZ for two weeks. Rat model. The remaining 20 rats were treated as normal control rats and the STZ abdomen was replaced with the same volume of saline. The rats were randomly divided into 2 groups,18 in each group: one group of Dzocine group and 2 weeks after the injection of STZ, and 2 weeks after the injection of STZ, the outer side of the thigh was injected intramuscularly by intramuscular injection of 2.52 mg/ kg, once a day, and the continuous muscle The meat was injected for 1 week; a group of diabetic neuropathic pain rats (Control group), with the same volume of physiological saline instead of Doxacin, the method was the same as above; in the normal group,18 groups were taken as the normal group (Normal group), and the same volume of physiological saline was used instead of the ground Zusin. The body weight, fasting blood glucose and PWT of each group were measured at 5 time points after injection of STZ (T0), the second week (T1), the third week (T2), the fifth week (T3) and the seventh week (T4), respectively. Three rats were used for immunohistochemical staining. After the anesthesia,4% paraformaldehyde solution was used for the fixation, and the spinal cord from the enlarged part of the thoracic waist of the rat was made into a wax block, and the immunohistochemical staining was performed to determine the immunopositive of the NMDA-2B receptor in the dorsal horn of the spinal cord of the rat. The number of nerve cells was measured; in the 3 rats, the spinal cord tissue was rapidly extracted at the enlargement of the thoracic and lumbar segment of the rat, and the m-2 B receptor was determined by means of the PT-PCR technique. RNA content. The analysis was performed using the SPSS17.0 statistical software, and the measurement data was level. The mean square standard deviation (x _% s) indicated that one-factor analysis of variance was used in the intra-group comparison, and t-test was used between the groups, and the difference between the groups was P0.05. difference Statistical significance. Results: The changes in body weight, fasting blood glucose and 50% contraction threshold of three groups of rats were compared with those of three groups: before the injection of STZ, the weight of three groups of rats, the fasting blood glucose and the PWT difference were not statistically significant; after the injection of STZ, the weight of the Dezocine group and the Control group in rats obviously, the fasting blood sugar is obviously increased, and P In the control group and Dezocine group, the weight of PWT in the control group and the Dezocine group was significantly higher than that of the control group (P0.05). There was no significant difference in the expression of NMDA-2B receptor in the spinal dorsal horn of the three groups (P0.05). Compared with the normal group, the number of NMDA-2B receptor-positive neurons in the two groups of the Dezocine group and the Control group was significantly higher than that of the normal group (P0.05). Results Compared with the control group, the number of NMDA-2B receptor-positive neurons in the Dezocine group was significantly lower at the time of T2 (P0.05), at the time of T3, T4. There was no significant difference in the expression of NMDA-2B receptor in Dezocine group (P0.05). Conclusion: Zusin can effectively relieve the pathological pain of diabetic neuropathic pain in rats.
