ABSTRACT
Objective To compare the timeliness, success and mortality rates between the modified carotid artery puncture method ( MCAPM) and standard suture method ( SSM) in the establishment of rat model of a middle cerebral ar?tery occlusion ( MCAO) . Methods Thirty?two male rats were randomly and equally assigned into MCAPM group and SSM group. The MCAO models were established by inserting a thread into the common carotid artery ( CCA) . 24 h after modeling, the rats of the two groups were evaluated with Bederson neurological scores, and the modeling success rate and mortality rate were analyzed. Results The suture insertion times, success rates and mortality rates of the MCAPM vs. SSM groups were (82?3 ±17?4) s versus (164?6 ± 22?0) s (P0?05), and 6?25% versus 18?75% (P>0?05). Conclusions MCAPM can be used to establish the rat model of MCAO due to its simplicity, mild wound and feasibility.
ABSTRACT
<p><b>OBJECTIVE</b>To compare the effective differences between deep needling and shallow needling at three acupoints around ear for subjective tinnitus.</p><p><b>METHODS</b>Fifty patients with subjective tinnitus were randomized divided into a deep needling group and a shallow needling group, 25 cases in each group. Twenty-two patients in the deep needling group and 20 patients in the shallow needling group were brought into statistic in the end. In the two groups, the three acupoints around ear and distal acupoints were both selected. The acupoints of the affected side such as Yifeng (TE 17), Tinghui (GB 2), Ermen (TE 21), Zhigou (TE 6), Zhongzhu (TE 3) and Hegu (LI 4) were adopted. Yifeng (TE 17), Tinghui (GB 2) and Ermen (TE 21) were acupunctured 30-38 mm in the deep needling group and 15-20 mm in the shallow needling group. The other acupoints were conventionally acupunctured in the two groups. The needles were retained for 30 min,once a day and five times a week for all patients. The treatment was continuously for 4 weeks in the two groups. Tinnitus handicap inventory (THI) scores, tinnitus grades and visual analogue scale (VAS) for tinnitus sound levels were observed before and after treatment, and the effects of the two groups were compared.</p><p><b>RESULTS</b>The total effective rate in the deep needling group was 59.1% (13/22), and it was better than 20.0% (4/20) in the shallow needling group (P < 0.05). In the deep needling, group, the THI score, tinnitus grade and the VAS score were improved than those before treatment (all P < 0.05). In the shallow needling group, the three above indices before and after treatment were not different in statistical significance (all P > 0.05). After treatment, all the three indices in the deep needling group were superior to those in the shallow needling group (all P < 0.05).</p><p><b>CONCLUSION</b>Acupuncture at the three acupoints around ear deeply could apparently improve tinnitus, and reduce tinnitus sound levels for subjective tinnitus. The effect is better than that by shallow needling at the three acupoints.</p>

@#Objective To explore the effects of cluster scalp acupuncture on the behavior and expression of bcl-2 in rats after acute cerebral infarction. Methods 72 male Wistar rats were randomly divided into sham operation group (A), model group (B) and cluster scalp acupuncture group (C), 24 rats in each group. According to time after cerebral infarction, each group was reassigned to 6 h, 24 h and 3 d subgroups, 8 rats in each subgroup. The acute cerebral infarction model was established with the middle cerebral artery occlusion. The effects of cluster scalp acupuncture on the behavior and expression of apoptosis-related gene bcl-2 in the rat brain tissues with acute cerebral infarction were tested at different time. Results 3 d after cerebral infarction, the score of neuronal function in group C was significantly lower than that of group B (P<0.01). The expression of bcl-2 in brain ischemic penumbra increased in group C at different time and reached its peak at 24 h. Compared with group B, there was a statistical difference (P<0.01). Conclusion Cluster scalp acupuncture can significantly reduce the neuronal function score of rats after acute cerebral infarction and then promote the recovery of movement function. The therapy can inhibit the apoptosis by increasing the expression of bcl-2 in penumbra zone of cerebral infarction.
ABSTRACT
@#Objective To explore the effect of cluster scalp acupuncture on pathological changes and the expression of nerve growth factor (NGF) and transforming growth factor (TGF) in rats after acute cerebral infarction.Methods30 male Wistar rats were randomly divided into the sham operation group (group A), model group (group B) and cluster scalp acupuncture group (group C) with 10 animals in each group. Animal model was made by the middle cerebral artery occlusion. The pathological changes and the expression of NGF and TGF in the brain tissues of rats were tested.ResultsOn the 7th day after operation, brain tissue of infarction area in the group B indicated significantly edema, neural cells decreased. Compared with the group B, the edema in the group C decreased and neural cells increased. At the same time, there were a few NGF and TGF expressions in hippocampus andcortex areas of the group A and group B, and there was no difference between the two groups ( P>0.05); but compared with the group A and group B, NGF and TGF in the group C increased significantly ( P<0.05, P<0.01).ConclusionCluster scalp acupuncture therapy can decrease edema, increase neural cells in infarction areas, as well as induce the expression of NGF and TGF in cortex and hippocampus.
ABSTRACT
Objective: To investigate the effect of scalp point-through-point acupuncture on 200 kDa neurofilament protein (NF-200) in rats with acute cerebral infarction and explore its mechanism on nerve plasticity in cerebral infarction rats. Methods: Healthy male Wistar rats were randomly allocated to sham operation (Group A), model (Group B) and acupuncture (Group C) groups. A rat middle cerebral artery occlusion (MCAO) model of cerebral ischemia was made. NF-200 mRNA was measured by reverse transcriptase polymerase chain reaction (RT-PCR) in each group on the 7th, 14th and 28th days. Results: The cerebral expression of NF-200 in group C was significantly different from those in groups A and B (P＜0.05); there was a significant difference between groups C and B or A at different time windows (P＜0.01),indicating that scalp point-through-point acupuncture could improve the cerebral expression of NF-200. Conclusion: Scalp point-through-point acupuncture can improve neural function,promote the recovery of limb function and increase the expression of NF-200 after cerebral ischemia, exerting a regulative effect on neuronal plasticity in the brain.
ABSTRACT
Objective: To evaluate the clinical efficacy of scalp penetrating technique plus rehabilitation therapy in treating acute cerebral hemorrhage. Methods: The patients were allocated randomly by computer into scalp acupuncture plus rehabilitation group (A),rehabilitation group (B) and Western medication control group (C).

The radioimmunoassay was adopted to determinate the content of ET and CGRP in plasma of patients.ResultsAfter treatment, contents of ET and CGRP of all patients were decreased significantly (P<0.01), but group A and group B had a significant difference compared with the group C (P<0.01), and there was also a significant difference between the group A and group B.ConclusionThe scalp point penetration combined with rehabilitation training can regulate the content of ET and CGRP in plasma and make them under a dynamic balance.
ABSTRACT
@#ObjectiveTo observe effects of rehabilitation training on behavior and sensory evoked potential of rats with acute cerebral infarction.Methods30 male Wistar rats were randomly divided into sham operation groups (group A), model group (group B), and rehabilitation group (group C). Animal model was made by blocking the middle cerebral artery (MCA). For each group, the Bederson Neural Function was scored and balancing wood, rotating bar, and net screen were tested at the 24 hours, 3rd day and 7th day after operation respectively. The sensory evoked potential (SEP) latency of each group was also tested right after operation and on the 7th day after operation.ResultsComparing with group A, Bederson Neural Function scores of groups B and C indicated significant differences at each time (P<0.01). The ability of grasping, walking and coordinating of all groups handicapped 24 hours after operation, however, with time continuing, every function of group A restored and that of group B or C improved partly, but showed significant difference compared with group A (P<0.01). On the 3rd day after operation, balancing wood test of group C was better than that of group B (P<0.05), on the 7th day after operation, except Bederson Neural Function scores, there were significant difference between groups C and B (P<0.01 or P<0.05). Right after operation, compared with group A, the SEP latency of group B and C showed significant difference (P<0.01), on the 7th day after operation, the SEP latency of group C improved significantly compared with itself right after operation (P<0.01).ConclusionThe rehabilitation training can improve the MCAO rats' ability of equilibrating,grasping and walking and adjust the abnormal latency of SEP after MCAO, and prevent the nerve cells from damage caused by ischemic trauma.
