[Effect of acupuncture intervention on 14-3-3 expression in cerebral cortex of hypoxic-ischemic brain damage rats].

OBJECTIVE: To observe the effect of acupuncture therapy on 14-3-3, Bcl-2 and Bax expression levels in the cerebral cortex in neonatal rats with hypoxic-ischemic brain damage(HIBD). METHODS: Timed pregnant Sprague-Dawley rat dams were delivered either vaginally (normal group), or by C-section (sham-operation group) or by C-section with 5 min of global anoxia (anoxia group), with 8 rats in each group. The rat pups of the anoxia group were randomly divided into model group and acupuncture group (n =8). Acupuncture stimulation of "Naosanzhen" "Niesanzhen" and "Zhisanzhen" acupoints was given begin- ning from the 14th day after birth, once daily for 7 consecutive days. All rat pups were killed by decapitation on day 21 after birth, and then 14-3-3, Bcl-2 and Bax immunoactivity (expression) in the cerebral cortex were detected by immunohistochemistry. RESULTS: In comparison with the normal group, the expression level of cerebral cortical 14-3-3 was significantly decreased, and that of Bax remarkably increased in the model group (P<0. 01, P<0. 05). Compared to the model group, cortical 14-3-3 and Bcl-2 expression levels were markedly up-regulated in the acupuncture group (P<0.01, P<0.05). Compared to the normal group, cortical 14-3-3 expression level was obviously lower, but Bax expression level significantly higher in the sham-operation group (P<0. 05, P<0. 01). No significant differences were found between the model and normal groups in the expression levels of Bcl-2, and between the acupuncture and model groups in the expression levels of Bax (P>0. 05). CONCLUSION: Acupuncture intervention can increase the expression of 14-3-3 and Bcl-2 in the cerebral cortex in HIBD rats.

[Treatment of autism children: observation on efficacy of behavior training with retention of needles on head].

OBJECTIVE: To observe the effect difference of behavior training with head needling retention and behavior training after acupuncture for autism children. METHODS: Sixty qualified autism children were divided randomly into simultaneous head needling retention and behavior training group (trial group) and behavior training after acupuncture treatment group (control group) with 30 case in each group. Retention needles on the head with simultaneous behavior training was applied for the trial group. The main acupoints included Sishen Xue, Dingshen Sanxue (3 points for mental tranquilization), Nao Sanxue (3 points for the function of brain), Shou Zhisanxue (3 points for mental activities on hand) and Zozhi Sonxue (3 points for mental activities on foot). Other points were combined according to conditions of patients. Needles on the 4 extremities were withdrawn first after 30 minutes, needles on head were remained during behavior training. While behavior training was applied to the control group when acupuncture treatment was completely accomplished. Treatments were applied once a day to both groups. And 3 months was taken as one observation cycle. Estimation was made on therapeutic effect and developing level of autism children with CARS and PEP. RESULTS: The total effective rate of the trial group was 83.3% (25/30), better than 66.7% (20/30) of the control group (P < 0.05). The CARS scores of both groups declined after the treatment. And the score of trail group was lower than the control group (all P < 0.05). While the PEP scores of both groups increased, and the score of trail group was higher than the control group (all P < 0.05). The increasing level of scores of cognitive understanding and cognitive expression were all better than the control group (all P < 0.05). CONCLUSION: The effect of behavior training with head needle retention on autism children is better than behavior training after acupuncture treatment, especially in enhancing cognition understanding and cognition expression.
