[Objective] To observe imaging changes of Lumbar Intervertebral Disc Protrusion(LIDP)treated by Leverage Location manipulation.[Methods] 33 patients with lumbar intervertebral disc protrusion were observed(male=19,female=14),4 cases of expand type,25 cases of the outstanding type,4 cases of the free type.Using lever to observe the CT imaging of the cases.[Results]The 24 cases had no change in degree of Intervertebral Disc Protrusion while 9 cases had the changes.29 cases changed the compression relation between the nerve root and the lumbar intervertebral protrusion.Another 4 cases had nothing changed.[Conclusion] Leverage location manipulation has a little effect on changing the degree of the lumbar intervertebral protrusion,but can change compression relation between the nerve root and the lumbar intervertebral protrusion which proves that leverage location manipulation has effect on curing the LIDP.

Hypoxic-ischemic brain damage is a serious complication of perinatal asphyxia. Enriched environment is the living condi-tions for the promotion of feeling, cognition and behavior. Enriched environment may promote the repairing of hypoxic-ischemic brain dam-age in term of praxiology, morphology and molecular biology, that enriched environment may regulate the secretion and release of various factors, and enhance synaptic plasticity, induce neuron regeneration, inhibit its apoptosis, and result in ethological and morphological recov-ery.

Objective To investigate the effect of exercise preconditioning on serum level of tumor necrosis factor α (TNF-α), interleukin (IL) -1β and IL-6 in rats after cerebral ischemia-reperfusion (I/R). Methods 24 male Sprague-Dawley rats were randomly divided into exercise preconditioning group (n=8), model group (n=8) and sham group (n=8). The middle cerebral arteries were occluded for 120 min and re-perfused. All the rats were evaluated with neurological deficit score 2 hours, 24 hours after I/R. The serum levels of TNF-α, IL-1β and IL-6 was detected with enzyme-linked immunosorbent, and the pathology was observed with HE staining 24 hours after I/R. Results The neurological deficit score decreased in the exercise preconditioning group compared with that in the model group, as well as the serum TNF-α, IL-1β and IL-6 (P<0.05) 24 hours after I/R. The pathological damage and interstitial edema alleviated in cerebral ischemia cortical, and the degeneration and necrosis of the neurons in the ischemic area significantly reduced in the exercise preconditioning group. Conclusion Exercise preconditioning may inhibit inflammatory response in I/R rats to protect neurological function from impairment.

Objective To study the effect of cluster needling of scalp acupuncture combined with rehabilitation on neurological function and expression of basic fibroblast growth factor (bFGF) and angiostatin (AS) in rats after focal cerebral ischemia. Methods 90 male Sprague-Dawley rats were randomly divided into sham operation group, model group, acupuncture treatment group, rehabilitation treatment group and acupuncture and rehabilitation treatment group, each group was further divided into 3 days, 7 days and 14 days subgroups (n=6). Permanent cerebral ischemia rat model was established according to Longa's method. The model group and the sham operation group accepted no treatment, the acupuncture treatment group was treated by cluster needling of scalp acupuncture, the rehabilitation treatment group received the treadmill training, the acupuncture and rehabilitation treatment group was treated by acupuncture and rehabilitation therapy. 3 days, 7 days, 14 days after operation, the neural function was evaluated with the modified Neurological Severity Score (mNSS), the expression levels of bFGF and AS proteins were detected by Western blotting. Results Compared with the model group, the acupuncture treatment group and the rehabilitation treatment group, mNSS decreased, the expression of bFGF protein increased, and the expression of AS protein decreased in the acupuncture and rehabilitation treatment group 3 days, 7 days, 14 days after operation (P<0.05). Conclusion Acupuncture and rehabilitation therapy can reduce the neurological function defect in rats with focal cerebral ischemia, which may be related to the upregulation of bFGF protein expression and down-regulation of AS protein expression.

Objective To observe the effect of acupuncture plus rehabilitation on neurologic deficit and the expression of vascular endothelial growth factor (VEGF) protein in cortex on the infarction side in rats with focal cerebral infarction, and to explore the action mechanism of acupuncture plus rehabilitation in promoting the recovery of impaired function in rats.Method Ninety healthy male Sprague-Dawley (SD) rats were randomized into a model group, an acupuncture group, a rehabilitation group, an acupuncture-rehabilitation group, and a sham operation group, and the five groups were further divided into three subgroups, i.e. 3 d, 7 d, and 14 d subgroups, 6 rats in each subgroup. The modified Zea-Longa method was adopted to prepare the model of middle cerebral artery occlusion (MCAO) on theright side. Rats in the acupuncture group received simulant scalp-points cluster needling; the rehabilitation group was intervened by treadmill exercise; the acupuncture-rehabilitation group was intervened by scalp-points cluster needling plus treadmill exercise; the model group and sham operation group didn't receive any interventions. The modified Neurological Severity Score (mNSS) was adopted to evaluate the rat's neurologic deficit, and Western blotting was used to detect the expression of VEGF protein in cortex on the infarction side.Result Neurologic deficit wasn't found in rats in the sham operation group. After 3-day treatment, the mNSSs in the acupuncture group, rehabilitation group, and acupuncture-rehabilitation group were insignificantly different from the score in the model group (P>0.05), while the differences were statistically significant respectively after 7-day and 14-day treatment (P<0.05). Respectively after 7-day and 14-day treatment, the mNSS of the acupuncture-rehabilitation group was significantly lower than that in the acupuncture group and rehabilitation group (P<0.05); there was no significant difference in comparing the mNSS between the acupuncture group and rehabilitation group (P>0.05). After 3-day treatment, the expression of VEGF protein in each treatment group was insignificantly different from that in the model group (P>0.05), while the expression of VEGF protein in each treatment group was significantly higher than that in the model group respectively after 7-day and 14-day treatment (P<0.05). Respectively after 7-day and 14-day treatment, the expression of VEGF in the acupuncture-rehabilitation group was significantly different from that in the acupuncture group and rehabilitation group (P<0.05); there were no significant differences in comparing the expression of VEGF at each time point between the rehabilitation group and acupuncture group (P>0.05).Conclusion Scalp-points cluster needling and rehabilitation both can improve the neurologic function in rat models of focal cerebral infarction, and enhance the expression of VEGF protein in infarction cortex, and the integration of acupuncture and rehabilitation can achieve a better result; the action mechanism is possibly related to the high expression of VEGF which can better promote the reconstruction and regeneration of the vessels in cerebral infarction area.

Objective To investigate the effect of electroacupuncture or exercise preconditioning on neurological function after focal ce-rebral infarction in rats and the possible mechanism. Methods A total of 24 male Sprague-Dawley rats were randomly divided into model group (n=6), sham group (n=6), exercise preconditioning group (n=6) and electroacupuncture preconditioning group (n=6). The model group and the sham group did not accept any treatment, while the exercise preconditioning group and the electroacupuncture precondition-ing group accepted treadmill training and electroacupuncture for two weeks, respectively. Their middle cerebral arteries were occluded with modified Longa's approach, except the sham group that was ligated the same arteries but did not result in infarction. They were evaluated with Neurologic Severity Scores (NSS) 24 hours after modeling, and the laminin expression in the ischemic area was detected with Western blotting. Results There was no neurological deficit in the sham group. The NSS was lower in both preconditioning groups than in the model group (P<0.05), but was not significant different between preconditioning groups (P>0.05). The expression of laminin was the most in the sham group, and was more in both preconditioning groups than in the model group (P<0.05), but was not significant different between pre-conditioning groups (P>0.05). Conclusion Preconditioning with exercise or electroacupuncture can both reduce the neurological deficits in rats after focal cerebral infarction, which may associate with the protection of laminin from inhibition in early stage.

Objective To investigate the effect of electro-acupuncture pretreatment on content of interleukin (IL)-1βand IL-6 in serum and ischemic penumbra, and apoptosis in ischemic penumbra in rats after cerebral ischemia-reperfusion injury. Methods Thirty-six male Sprague-Dawley rats were randomly divided into sham group (n=12), model group (n=12), and electro-acupuncture pretreatment group (n=12). The middle cerebral arteries were occluded for 120 minutes and reperfused. Twenty-four hours after reperfusion, the level of IL-1βand IL-6 in serum and brain tissue was detected with enzyme-linked immunosorbent, and apoptosis of ischemic penumbra was detected with TU-NEL. Results The content of IL-1βand IL-6 in the serum and brain tissue, and the number of TUNEL-positive cells decreased in the elec-tro-acupuncture pretreatment group compared with that in the model group (P<0.01). Conclusion Electro-acupuncture pretreatment may in-hibit inflammatory response and apoptosis in cerebral ischemia-reperfusion injury.

Objective To explore the effect of acupuncture-rehabilitation therapy on neurological function and expression of Flt-1 and Flk-1, members of vascular endothelial growth factor receptors, after permanent focal cerebral ischemia in rats. Methods Ninety male Sprague-Dawley rats were divided into five groups, namely sham group, model group, acupuncture group, rehabilitation group and acupunc-ture-rehabilitation group, and each group was further divided into 3-day, 7-day and 14-day subgroups, equally. Their middle cerebral arteries were occluded except those of sham group. The sham and model groups accepted no treatment, while the acupuncture group accepted clus-ter needling of scalp acupuncture, the rehabilitation group accepted treadmill training, and the acupuncture-rehabilitation group accepted both acupuncture and treadmill training. They were assessed with modified Neurologic Severity Score (mNSS) 3, 7 and 14 days after model-ing, while the expression of Flt-1 and Flk-1 were determined with Western blotting. Results The mNSS score reduced in all the treatment groups (P<0.05) compared with that of the model group at every time point, and was the least in the acupuncture-rehabilitation group (P<0.05) 7 and 14 days after modeling among the treatment groups. Meanwhile, the expression of Flt-1 and Flk-1 protein increased in all the treatment groups (P<0.05), and was the most in the acupuncture-rehabilitation group (P<0.05). Conclusion Acupuncture-rehabilitation thera-py can promote the neurological function recovery in rat with permanent focal cerebral ischemia, which may be associated with the continu-ous inducement of Flt-1, Flk-1 protein expression in ischemic penumbra cortex.

Objective To investigate the effect of electroacupuncture (EA) pretreatment on neurological function, and the expression of Toll-like receptor 4 (TLR4) and nuclear factorκB (NF-κB) protein in ischemic penumbra after cerebral ischemia-reperfusion (CIR) injury. Methods A total of 36 male Sprague-Dawley rats were randomly divided into sham group (n=12), model group (n=12) and EA group (n=12). The later two groups were occluded their right middle cerebral arteries for two hours and reperfused. The EA group was pretreated with EA at Baihui (GV20) for two weeks before modeling. They were assessed with modified Neurological Severity Scores (mNSS), the injury in ischemic brain was detected with HE staining, and the expression of TLR4 and NF-κB protein in ischemic penumbra were detected with Western blotting, 24 hours after reperfusion. Results The score of mNSS decreased (P<0.05), the injury of brain tissue ameliorated, and the expression of TLR4 and NF-κB decreased in ischemic penumbra (P<0.05) in EA group compared with those in the model group. Conclu-sion EA pretreatment can reduce the injury and improve the neurological function in rats after CIR by down-regulating the expression of TLR4 and NF-κB protein in ischemic penumbra.

Objective To explore the effect of Taijiquan on motor function and depression in patients with post-stroke depression. Meth-ods From January to October, 2015, 60 stroke patients with depression were randomly divided into control group (n=30) and Taijiquan group (n=30). Both groups accepted routine rehabilitation, while Taijiquan group accepted another training of six actions from simplified Taijiquan. They were assessed with Fugl-Meyer Assessment (FMA), Barthel Index (BI) and Hamilton Depression Rating Scale (HAMD) be-fore, and four and eight weeks after treatment. Results The scores of FMA and BI increased more in Taijiquan group than in the control group after treatment (t>2.351, P<0.05), while the score of HAMD decreased more (t>2.169, P<0.05). Conclusion Taijiquan can relieve the depression and improve the motor and activities of daily living in patients with post-stroke depression.
