ABSTRACT
PURPOSE: To investigate the effect and underlying mechanism of Aceglutamide on motor dysfunction in rats after cerebral ischemia-reperfusion. METHODS: Adult male Sprague-Dawley rats were subjected to 2 h transient middle cerebral artery occlusion (MCAO). Aceglutamide or vehicle was intraperitoneally given to rats at 24 h after reperfusion and lasted for 14 days. Subsequently functional recovery was assessed and number of tyrosine hydroxylase (TH)-positive neurons in substantia nigra (SN) was analyzed. Tumor necrosis factor receptor-associated factor 1(TRAF1), P-Akt and Bcl-2/Bax were determined in mesencephalic tissue by Western blot method. PC12 cells and primary cultured mesencephalic neurons were employed to further investigate the mechanism of Aceglutamide. RESULTS: Aceglutamide treatment improved behavioral functions, reduced the infarction volume, and elevated the number of TH-positive neurons in the SN. Moreover, Aceglutamide significantly attenuated neuronal apoptosis in the SN. Meanwhile Aceglutamide treatment significantly inhibited the expression of TRAF1 and up-regulated the expression of P-Akt and Bcl-2/Bax ratio both in vitro and in vivo. CONCLUSIONS: Aceglutamide ameliorated motor dysfunction and delayed neuronal death in the SN after ischemia, which involved the inhibition of pro-apoptotic factor TRAF1 and activation of Akt/Bcl-2 signaling pathway. These data provided experimental information for applying Aceglutamide to ischemic stroke treatment.

OBJECTIVE: To explore the effective therapeutic method in the treatment of idiopathic sudden hearing loss (ISHL). METHODS: One hundred and eighty-eight cases of ISHL were randomized into a warming-promoting needling group (74 cases), a conventional acupuncture group (56 cases) and a medication group (58 cases). In the conventional acupuncture group, the conventional needling technique was applied to Baihui (GV 20), Fengchi (GB 20), Yifeng (TE 17), Tinggong (SI 19), Touqiaoyin (GB 11) and Zhigou (TE 6) on the affected side. The treatment was given 5 times each week. Totally, the treatment of 6 weeks was required. In the warming-promoting needling group, on the basic treatment as the conventional acupuncture group, the warming-promoting needling technique was applied to Fengchi (GB 20). In the medication group, the intravenous drop with salvia injectio and mecobalamin was prescribed, once per day, for 10 days totally. Meanwhile, Erlong Zuoci Wan was prescribed for oral administration, 8 pills each time, three times a day for 30 days continuously. RESULTS: All of the three therapeutic methods achieved the effect on ISHL. The total effective rate was 89.2% (66/74) in the warming-promoting needling group, which was better than 62.5% (35/56) in the conventional acupuncture group and 53.4% (31/58) in the medication group (both P<0.01). CONCLUSION: The warming-promoting needling techinque achieves the significant efficacy on ISHL. The hearing improvement is superior to that treated with either the conventional needling technique or medication.

OBJECTIVE: To observe the effect of acupuncture on intelligence quotient (IQ) in children with mental retardation (MR). METHODS: One hundred children with MR were randomly divided into an acupuncture group and a control group, 50 in each. There were 37 and 36 cases with complete data in the former and latter group respectively. Four-week treatment constituted a course, the comprehensive therapeutic effect of two groups was compared after 3 courses of treatment, and the influence of acupuncture on IQ was estimated. RESULTS: The total effective rate in the acupuncture group was 78.4%, better than 30.56% in the control group, the difference being significant (P < 0.01). Both groups were improved in IQ but the effect of the former group was better than that of the latter group (P < 0.05). CONCLUSION: Acupuncture can obviously improve IQ of children suffering from MR.

OBJECTIVE: To explore the mechanism of scalp catgut embedding for treatment of Parkinson's disease. METHODS: Parkinson's disease model rats were prepared, and randomly divided into a model group, scalp acupuncture group, medication group, with a control group set up. The scalp acupuncture group were treated with catgut embedding at "the chorea-trembling conroued area" lateral to "Baihui" (GV 20) and the medication group with intra-gastric perfusion of L-dopa suspension. After treatment for 30 days, behavior indexes were investigated and malondialdehyde (MDA) and nitric oxide (NO) contents and superoxide dismutase (SOD) activity in the brain were detected. RESULTS: MDA content in the brain of the model rats were significantly decreased (P < 0.01), NO level significantly increased (P < 0.05) by scalp catgut embedding, with no significant change of SOD activity (P > 0.05); and the behavior indexes and tissue and form of the brain had significant improvement. CONCLUSION: Scalp catgut embedding has regulative action on anti-oxidant enzyme system in the Parkinson's disease rats, has significant improvement of cells, tissues and form of the brain.
