[On connotation of Jin's three-needle technique].

Jin's three-needle technique is named after Professor JIN Rui. The connotation of Jin's three-needle technique is summarized by his followers through long-term teaching and clinical practice. His principle and method of point combination are based on syndrome differentiation of acupuncture. And his unique needling technique and treating principle of mental tranquilization also play an important role in his clinical practice.

[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.
