Objective To investigate the effect of acupuncture-rehabilitation therapy on cognitive function of vascular dementia (VaD) rats with type 2 diabetes mellitus (T2DM) and its mechanism. Methods Seventy-five healthy male SD rats were selected to establish T2DM models by peritoneal injection of streptozotocin. Twelve of them were randomly selected as the sham operation group, and the remaining 63 rats were continued to prepare VaD models. Among 63 VaD model rats, 48 were successfully established and randomly divided into the model group, treadmill training group, scalp acupuncture group and acupuncture-rehabilitation group, with 12 rats in each group. On the fifth day after the end of VaD preparation, rats in the acupuncture-rehabilitation group were given scalp acupuncture, and received treadmill training during needle retention; rats in the scalp acupuncture group were only treated with scalp acupuncture, and rats in the treadmill training group only received treadmill training. The rats in the sham operation group and the model group were not treated. Each group was randomly divided into 14 and 28 days of intervention, and we selected 6 rats at each time point; 14 days of intervention required 14 days of continuous treatment and 28 days of intervention required 28 days of continuous treatment. Morris water maze test was performed on the 14th and 28th days of intervention to detect learning and memory function. After the Morris water maze experiment, we injected excessive anesthesia into the abdominal cavity to kill the rats and decapitated to obtain their brains. The levels of superoxide orgotein dismutase (SOD), maleic dialdehyde (MDA), glutathione (GSH) and glutathione peroxidase (GSH-Px), which were related to oxidative stress, and acetylcholine (Ach) and acetylcholinesterase (AchE), which were related to cholinergic neurotransmitters, were determined by ELISA in one side of the hippocampus tissues. Nissl staining was performed on the other side of hippocampus tissues to observe the morphological changes of hippocampal neurons. Results The escape incubation period at 14 and 28 days of intervention in the model group was significantly longer than that in the sham group, and the number of crossing platform and the percentage of target quadrant residence time were significantly lower than those in the sham group (all P＜0. 05).The escape incubation period at 14 and 28 days of intervention in the treadmill training group, scalp acupuncture group and acupuncture-rehabilitation group were dramatically shorter than that in the model group, and the number of crossing platform and the percentage of target quadrant residence time were dramatically higher than that in the model group (all P＜0. 05). After 14 and 28 days of intervention, the escape incubation period of the acupuncture-rehabilitation group was significantly shorter than that of the treadmill training group and scalp acupuncture group, and the number of crossing platform and the percentage of target quadrant residence time were significantly higher than those of the treadmill training group and scalp acupuncture group (all P＜0. 05). The escape incubation period at 14 days of intervention in the treadmill training group, scalp acupuncture group and acupuncture-rehabilitation group were longer than that at 28 days of intervention, but the number of crossing platform and the percentage of residence time in target quadrant were notably lower than those at 28 days of intervention (all P＜0. 05). The content of SOD, GSH, GSH-Px, and Ach at 14 and 28 days of intervention in the model group was significantly lower than that in the sham group, and the content of MDA and AchE was significantly higher than that in the sham group (all P＜0. 05). The content of SOD, GSH, GSH-Px, and Ach at 14 and 28days of intervention in the treadmill training group, scalp acupuncture group and acupuncture-rehabilitation group was dramatically higher than that in model group, and the content of MDA and AchE was dramatically lower than that in the model group (all P＜0. 05). After 14 and 28 days of intervention, the content of SOD, GSH, GSH-Px, and Ach of the acupuncture-rehabilitation group was significantly higher than that of treadmill training group and scalp acupuncture group, and the content of MDA and AchE was significantly lower than that of the treadmill training group and scalp acupuncture group (all P＜0. 05). More Nissl bodies were found in CA1 region of hippocampus and arranged neatly in sham operation group. Compared with the sham operation group, the number of Nissl bodies in CA1 region of hippocampus of the model group significantly decreased and the neuron loss was obvious at 14 days after intervention. Compared with the model group, the number of Nissl bodies increased in the treadmill training group, scalp acupuncture group and acupuncture-rehabilitation group at 14 days after intervention, but the arrangement was slightly disordered. Compared with 14 days of intervention, the number of Nissl bodies in CA1 region of hippocampus of the treadmill training group, scalp acupuncture group and acupuncture-rehabilitation group notably increased after 28 days of intervention, and the arrangement was more orderly. Whether it was 14 days or 28 days, the number and uniformity of Nishi bodies in hippocampal CA1 region of acupuncture-rehabilitation group were better than those of the treadmill training group and scalp acupuncture group. Conclusion Acupuncture-rehabilitation therapy may improve the cognitive function of VaD rats with T2DM by reducing oxidative stress damage and regulating cholinergic transmitter release in hippocampus, and the longer treatment time, the better the therapeutic effect.

BACKGROUND: At present, it is considered that the volume of intervertebral bone graft is one of the factors affecting the intervertebral fusion rate, but the same volume of intervertebral bone graft leads to different release area of intervertebral bone graft and endplate due to individual differences, and the impact of release area of intervertebral bone graft and endplate on the intervertebral fusion rate is rarely analyzed. OBJECTIVE: To investigate the effect of area ratio of interbody autograft on intervertebral fusion rate during posterior lumbar interbody fusion. METHODS: Clinical data of 93 patients who underwent posterior lumbar interbody fusion in Department of Spinal Surgery, Affiliated Hospital of Southwest Medical University from January 2017 to December 2018 were retrospectively analyzed. The preoperative intervertebral space height, upper and lower endplate area, Oswestry disability index and visual analogue scale score, Cage size and the amount of autologous bone, and area of autologous bone graft (the area of autologous bone contacting the upper and lower endplates) were recorded, and the average value was calculated. According to the percentage of autogenous bone graft area in the total endplate area measured one week after operation, they were divided into group A (area ratio of interbody autograft < 16%), group B (16% ≤ area ratio of interbody autograft ≤ 24%) and group C (area ratio of interbody autograft > 24%). X-ray and CT examinations were performed at 6 and 12 months and the last follow-up. The direction of cage placement was observed in the three groups. The height of intervertebral space, the area ratio of intervertebral autograft bone graft, brantigan score, Oswestry disability index and visual analogue scale score were recorded at the follow-up. The measurement was performed by two spine surgeons, and repeated at an interval of one week to test inter observer and intra observer reliability. The effect of the area of autologous bone graft on the intervertebral fusion rate was compared and analyzed. RESULTS AND CONCLUSION: (1) The inter observer and intra observer reliabilities were 0.924 and 0.913, respectively. (2) All patients were followed up for more than 12 months. There were no significant differences in age, gender and surgical segment among the three groups (P > 0.05). There were no significant differences in preoperative intervertebral height, Oswestry disability index and visual analogue scale score among the three groups (P > 0.05). (3) There were 27 cases in group A, including 26 cases of oblique placement and 1 case of transverse placement, 32 cases in group B, including 2 cases of oblique placement and 30 cases of transverse placement, 34 cases in group C, 1 case of oblique placement and 33 cases of transverse placement. (4) There was no significant difference in the amount of intraoperative autologous bone extraction among the three groups (P > 0.05), and the average height of intervertebral space in group A was higher than that in group B and group C one week after operation (P=0.022, P=0.00). The area of autogenous bone graft in group A was smaller than that in group B and group C (P=0.000, P=0.000). (5) At 6 and 12 months after operation, the fusion rate in group A (70.4%, 88.9%) was lower than that in group B (84.4%, 100%) and group C (88.2%, 100%), and the Brantigan score in group A was lower than that in group B (P=0.027, P=0.020) and group C (P=0.018, P=0.001). (6) At the last follow-up, there was no significant difference in Oswestry disability index and visual analogue scale score among the three groups (P > 0.314). The height loss of intervertebral space in group A was greater than that in group B and group C (P=0.007, P=0.013). The increased area of intervertebral fusion in group A was lower than that in group B and group C (P=0.003, P=0.000). There was no significant difference in fusion rate and Brantigan score among groups A, B and C (P=0.902, P=0.712). (7) It is suggested that the percentage of an area ratio of interbody autograft in the total endplate area greater than or equal to 16% can effectively improve the interbody fusion rate and reduce the risk of late intervertebral space collapse.

The raw ingredients of the secondary reformer have been changed for the replacement of raw gas in an TCT-AMV ammonia plant. In order to evaluate t he effect of oxygen-rich ingredients change, a numerical simulation is conducted for the Kellogg burner of secondary reformer used in the factory. The results indicate that, when ingredients are changed, the high temperature region of the secondary reformer burner is shifted downward, the outlet temperature distortion increases and may cause the catalyst layer to be poisoned. Based on the analysis, some optimized design schemes are proposed for the new working conditions, and the burner works well in practice. The simulation results and optimized design scheme are verified. [ABSTRACT FROM AUTHOR]
