To give the considerations on the syndrome differentiation and acupuncture treatment of diabetic peripheral neuropathy, generalize its pathogenesis and summarize treatment rules, this paper reviews and analyzed 52 articles on acupuncture treatment in recent years. It is believed that diabetic peripheral neuropathy is rooted from qi-yin deficiency and presented with blood stasis and collateral obstruction; many organs are affected, the liver, kidney,spleen and stomach in particular; the treatment principle concentrates on unblocking collaterals and regulating organs; treatment centers on limb acupoints, Back-Shu point and Front-Mu point;acupuncture treatment should be adopted early as possible and its clinical efficacy is rather good.

Objective To observe the abnormality of gray matter volume and density in patients undergoing postoperative delirium (POD).Methods Forty-seven cases of aged patients, 26 males and 21 females, aged 60-75 years, ASA physical status Ⅱ or Ⅲ, were selected.On the third day after operation, cognitive function estimation was performed.The patients were assigned into group POD and group C according to whether POD occurred and brain magnetic resonance imaging (MRI) scanning was implemented.The discrepancy in gray matter volume and density between the two groups were compared using voxel-based morphometry method (VBM).Correlation analysis was performed between the corresponding parameters in the regions where notable differences between the two groups existed and minimum mental state examination (MMSE) score were found.Results Global gray matter volume of group POD was notably lower than that of group C (P<0.01).Cerebrospinal fluid volume of group POD was significantly higher than that of group C (P<0.01).Gray matter volume of bilateral frontal gyrus and right parahippocampus was remarkably reduced in group POD (P<0.001).Gray matter density of bilateral hippocampus and right parahippocampus decreased significantly (P<0.001).Right parahippocampal gray matter volume was positively correlated with MMSE score in POD patients (P<0.05).Conclusion Structural abnormality in frontal regions, hippocampus and parahippocampus may play an important role in pathogenetic and developing process of POD.Gray matter volume in the right parahippocampus may be one of reference index for POD severity.

Objective To study the molecular mechanism of glutamate receptor-6 (GluR6) in the pathogenesis of epilepsy. Methods Seizure model of SD rats was induced by intraperitoneal injection of kainate (KA). Immunoprecipitation and immunoblotting were performed to examine the interactions of GluR6 and MLK3 with PSD95 at various time points after KA injection. The effect of Tat-GluR6-9c on the MLK3 phospharylation induced by kainate was observed with immunoblotting and immunohistochemistry. Results The assembly of GluR6 and MLK3 with PSD95 was induced after KA hippocampal CA3 region, and bagan to decrease one day later. Pretreatment after KA injection in CA3 region (P<0.05). Conclusion KA induces the assembly of the GluR6-PSD95-MLK3 signaling module and subsequently activates MLK3, which ultimately results in brain injury.
