Objective To explore the effect of the joint edaravone in early rehabilitation on the prognosis of patients with ischemic stroke.Methods The general branch of Kailuan group of patients with ischemic stroke who were conformed to the 1995 national conference on the 4th cerebrovascular diagnostic criteria with head CT or MRI imaging diagnosis,were collected from January 2012 to December 2014.A total of 324 cases were the first onset,who had been treated with conventional drugs,and were randomly divided into the observation group(edaravone associated with early rehabilitation)and the control group(early rehabilitation)with 162 cases in each group.Patients of the observation group were given venous application of edaravone and received the standardized rehabilitation treatment within 48 hours.The control group were given standard rebabilitation therapy at 2 weeks after attacked.NIHSS and MMSE scores of the two groups of patients were evaluated at the beginning of the rehabilitation course,4 weeks and 12 weeks of the treatments.Results There were no statistically significant difference and the clinial manifestations of the lesion site between the two groups of patients on admission.At the beginning of the rehabilitation,the NIHSS and MMSE score of control group were statistically significant different from that of observation group [NIHSS:(14.8 ±5.3)vs.(16.1 ±5.1),PNIHSS =0.049;MMSE:(15.9 ±6.3)vs.(14.2 ±6.2),PMMSE =0.041].The sec-ond and third evaluation were respectively conducted at 4 weeks[NIHSS:(10.1 ±6.3)vs.(8.2 ±5.7),MMSE:(17.7 ±5.5)vs.(20.9 ±5.9)]and 12 weeks[NIHSS:(6.6 ±4.9)vs.(4.7 ±3.6),MMSE:(21.0 ±4.8)vs. (24.6 ±4.9)].The results of the observation group were significantly better than the control group(P4W NIHSS =0.036,P4W MMSE =0.035;P12W NIHSS =0.006,P12W MMSE =0.003),and the differences were statistically significant. Conclusion Edaravone associated with early rehabilitation can obviously improve the prognosis of patients with ischemic stroke.

OBJECTIVE:To observe the clinical efficacy and safety of edaravone combined with early rehabilitation in the treat-ment of cerebral hemorrhage,and to provide clinical evidence for rehabilitation management and drug treatment of cerebral hemor-rhage patients. METHODS:168 patients with cerebral hemorrhage,collected from neurology department of our hospital during Jan. 2012 to Dec. 2014,were randomly divided into observation group and control group with 84 cases in each group. Both groups re-ceived routine treatment;observation group was additionally given edaravone intravenously on the basis of routine treatment,and be-gan to receive standardized rehabilitation treatment within 48 hours after the onset of symptom;control group began to receive stan-dardized rehabilitation treatment 2 weeks after the onset of symptom. NIHSS and MMSE score of 2 groups were conducted before re-habilitation treatment,and after 4 and 12 weeks of treatment. RESULTS:There was no statistically significant difference in lesion site and clinical manifestations between 2 groups on admission(P>0.05);both NIHSS and MMSE score of observation group were better than those of control group after 4 and 12 weeks of treatment,there was statistical significance(P<0.05). CONCLUSIONS:Edaravone associated with early rehabilitation can obviously improve the prognosis of patients with cerebral hemorrhage.

Objective: To observe the effects of electroacupuncture (EA) at Neiguan (PC6) on arrhythmia during acute myocardial ischemia-reperfusion and the expression of connexin 43 (Cx43) in rats. Methods: A total of 40 Sprague-Dawley male rats were used. Ten rats were randomly selected as the blank group, and the remaining 30 rats were randomly divided into a model group and an EA group, with 15 rats in each group. Before modeling, rats in the EA group received one session of EA intervention at bilateral Neiguan (PC6) for 30 min; the other groups were treated with the same grasping and anesthesia for 30 min without intervention. PowerLab physiological recorder was used to record electrocardiograph within 30 min of infarction. After the experiment, cardiac tissue and serum were collected from rats. Hematoxylin-eosin (HE) staining was used to observe the morphological changes of myocardial tissue in the ventricular infarction area of rats in each group. The expression of Cx43 protein in the myocardium of each group was detected by Western blotting (WB). Enzyme-linked immunosorbent assay (ELISA) was used to determine the activity of Na+-K+-ATPase in myocardial tissue and the serum content of endogenous digitalis-like factor (EDLF) in rats. Results: There was no statistical difference in arrhythmia score between the EA group and the model group, but the total duration and average duration of arrhythmia in the EA group were decreased (P<0.01). HE staining showed that compared with the blank group, myocardial cells in the model group were disorganized and seriously damaged. The pathological changes in the EA group were similar to those in the model group, but the damage was relatively minor. The results of WB showed that compared with the blank group, the Cx43 expression in myocardial tissue of the model group was decreased (P<0.01); compared with the model group, the Cx43 expression in the EA group was increased (P<0.01); compared with the blank group, the Na+-K+-ATPase activity in myocardial tissue of the model group was significantly decreased (P<0.01); compared with the model group, the Na+-K+-ATPase activity in the EA group was increased (P<0.01). ELISA results showed that compared with the blank group, the serum EDLF content in the model group was significantly increased (P<0.01); compared with the model group, the EDLF content in the EA group was decreased (P<0.01). Conclusion: EA at Neiguan (PC6) can delay and reduce the onset of arrhythmia during myocardial infarction in the rat model of myocardial ischemia-reperfusion. Its mechanism of action may be related to the regulation of the Cx43 expression in myocardial tissue, improvement of the activity of Na+-K+-ATPase in myocardial tissue, and increase in the content of serum EDLF.

OBJECTIVETo observe the effects of preventative moxibustion on adenosine monophosphate-activated protein kinase (AMPK) and mammalian target of rapamycin (mTOR) in myocardial tissue in rats with exhaustive exercise, and to explore the action mechanism of preventative moxibustion for myocardial injury by exhaustive exercise.

METHODSEighteen SD male rats were randomly divided into a blank group, an exhaustive exercise group and a moxibustion group, 6 rats in each one. Rats in the blank group were treated with immobilization for 5 min per day, without any intervention. Rats in the exhaustive exercise group were treated with no intervention in the first 10 days. Rats in the moxibustion group were treated with moxibustion at "Zusanli" (ST 36) and "Guanyuan" (CV 4), 5 cones for each acupoint, for 10 days.On 11th day, rats in the exhaustive exercise group and moxibustion group were sacrificed to collect sample after exhaustive swimming, and time of exhaustive exercise was recorded. HE staining was used to observe the inflammatory changes of myocardial tissue; colorimetric method was used to measure lactic dehydrogenase (LDH), activity of superoxide dismutase (SOD) and malonaldehyde (MDA); immune suppression method was used to measure the content of creatine kinase isoenzyme (CK-MB) in serum; Elisa method was used to measure the content of troponinT (cTnT) in serum; western blot method was applied to measure the content of AMPKα2 and mTOR in myocardial tissue.

RESULTSThe time of exhaustive exercise was (4 831.17±689.88) s in the moxibustion group, which was longer than (3 509.50±1 232.49) s in the exhaustive exercise group (<0.05); HE staining indicated structure of the myocardium was clear and inflammatory cell infiltration was reduced in the moxibustion group. Compared with the blank group, the contents of serum LDH, CK-MB, cTnT were increased in the exhaustive exercise group (all<0.05); MDA content was increased and SOD activity was decreased (both<0.05); the AMPK α2 content in myocardial tissue was increased and the mTOR content was decreased (both<0.05). Compared with the exhaustive exercise group, the contents of serum LDH, CK-MB, cTnT were reduced in the moxibustion group (all<0.05); MDA content was decreased and SOD activity was increased (both<0.05); the AMPKα2 content in myocardial tissue was increased, and the mTOR content was decreased (both<0.05); AMPKα2 and mTOR were negatively correlated (=-0.764,<0.05).

CONCLUSIONSPreventative moxibustion is likely to regulate the expression of AMPK and mTOR to induce signaling pathway to recover myocardial injury by exhaustive exercise.

OBJECTIVE: To investigate the difference of protective effect of electroacupuncture (EA) at different times pretreating myocardial ischemia-reperfusion injury (MIRI) and the protein expressions of ULK1 and Beclin-1 in myocardial tissue, so as to explore the relation of the difference and autophagic mechanism. METHODS: Sixty-three male SD rats were randomized into 7 groups, a sham group, a model group, an EA pretreating for 1 d (EA-1d) group, an EA pretreating for 2 d (EA-2d) group, an EA pretreating for 3 d (EA-3d) group, an EA pretreating for 4 d (EA-4d) group, an EA pretreating for 5 d (EA-5d) group, 9 rats in each group. All the rats in the pretreating groups were treated with EA 1-5 days before MIRI surgery. EA (2 Hz/100 Hz, 2 mA) was used at bilateral "Neiguan (PC 6)" for 20 min. All the rats except for those in the sham group was underwent left thoracotomy and ligation of the left anterior descending (LAD) coronary artery for 30 minutes followed by 4 hours of reperfusion to establish the MIRI model. The same operation was performed in the sham group except for the ligation of the LAD. Throughout the experiment, electrocardiogram was continuously monitored. The myocardial infarct sizes were assessed by Evans blue and triphenyltetrazolium chloride (TTC) staining. The serum concentrations of cardiac troponinⅠ(cTnⅠ) was detected by ELISA. The expressions of ULK1 and Beclin-1 in the heart tissues were analyze by Western blot. RESULTS: Compared with the sham group, the concentrations of cTnⅠ and the protein expressions of ULK1 and Beclin-1 increased in the model group (all <0.05). Compared with the model group, the infarct sizes decreased in the EA-1d, EA-2d, EA-3d, EA-4d and EA-5d groups (all <0.05), with less risk sizes in the EA-3d, EA-4d and EA-5d groups (all <0.05). The levels of cTnⅠin the EA-4d and EA-5d groups decreased ( both <0.05); the expressions of ULK1 protein decreased in the EA-1d, EA-2d, EA-3d, EA-4d and EA-5d groups (all <0.05); the expressions of Beclin-1 protein decreased in the EA-2d, EA-3d, EA-4d and EA-5d groups (all <0.05). The infarct sizes in the EA-4d and EA-5d groups were lower than that in the EA-1d group (both 0.05). The cTnⅠconcentration in the EA-4d group was less than that in the EA-1d group (<0.05). CONCLUSION Pretreatment with EA for 1-5 days can improve the infarct size in MIRI, with better effect of the pretreatment for 4-5 days. The cardioprotective effect may be related to the inhibition of autophagy. But the difference of the protective effects is not related to the protein expressions of ULK1 and Beclin-1.
