Objective To explore the effect of gastrodia elata on learning and memory abilities and synaptic transmission protein(P38,Ca2+ -CaMK Ⅱ α,CREB)expression of hippocampus in model rats with Alzheimer's disease(AD).Methods 24 adult Wistar rats were randomly divided into control group,test group and intervention group.A dose of Aβ1-40 was injected into the hippocampus of rats on test group and intervention group,the control rats were injected with normal saline.When the models were successful,the rats of control group and test groups were given with sodium carboxymethyl cellulose(50g/kg),the rats of intervention group were given with gastrodia elata powder( 50 g/kg),lasting 15 days,Morris water maze test was used for learning and memory abilities study.The expression of P38,Ca2+-CaMK Ⅱ α and CREB protein were detected by immunohistochemistry method.Results Behavioral tests showed the mean escape latencies and search time of test group were obviously increased than those of control group and intervention group,the percentage of search distance on test groups was less than that of control group and intervention group(P ＜ 0.01 ).Immunohistochemistry results showed P38,Ca2+- CaMK Ⅱ α and CREB positive cells and optical density in hippocampus CA1 on test group were less than those of control group and intervention group ( all P ＜ 0.01 ) ( P38:58.92 ± 10.82,0.208 ± 0.037 ; Ca2+-CaMK Ⅱ α:72.38 ± 14.67,0.174 ± 0.036 ; CREB:53.86 ±5.31,0.161 ±0.043 in test group;P38:87.32 ±9.56,0.371 ±0.046 ; Ca2+ -CaMK Ⅱ α:98.16 ± 16.29,0.283 ± 0.051 ; CREB:86.76 ± 7.73,0.356 ± 0.052 in intervention group; P38:102.54 ± 16.73,0.563 ± 0.078 ; Ca2 + -CaMK Ⅱ α:123.46 ± 17.65,0.436 ± 0.057 ; CREB:125.43 ±9.16,0.524 ± 0.057 in control group ).Conclusion Gastrodia elata can treat AD by increasing expression of P38,Ca2 + -CaMK Ⅱ α and CREB.

OBJECTIVETo observe the impacts on the muscle strength in the patients of stroke-induced acroparalysis treated with Xunjingcuiqi needling technique.

METHODSOne hundred patients were randomized into a Xunjingcuiqi group and a routine acupuncture group, 50 cases in each group. In the routine acupuncture group, the routine acupuncture technique was adopted at the main acupoints, such as Shangxing (GV 23), Baihui (GV 20), Dicang (ST 4), Quchi (LI 11), Huantiao (GB 30) and Zusanli (ST 36), etc. In Xunjingcuiqi group, on the basis of the routine acupuncture technique, Xunjingcuiqi needling technique (pricking technique was quickly applied with the filiform needle along the running course of meridian to promote the conduction of meridian qi) was added. For the patients being hard to feel the needling sensation and with the muscle strength of 0 to 1 degree, Dongzhencuiqi technique was supplemented at shu-stream points of yang meridians (after qi arrival, the needling manipulation with limb movement was given to promote the conduction of meridian qi). The treatment was given once every day in the two groups. Ten treatments made one session. Three sessions of treatment were required. At the end of each session treatment, the muscle strength and clinical efficacy were assessed.

RESULTSIn the 1st, 2nd and 3rd sessions of treatment, 20, 24 and 36 cases achieved the 3 to 5 degrees muscle strength in Xunjingcuiqi group, respectively; and 6, 10 and 15 cases achieved the 3 to 5 degrees muscle strength in the routine acupuncture group. The differences were significant statistically in comparison of the two groups (P < 0.01, P < 0.05). The markably effective rates were 60.0% (30/50), 64.0% (32/50) and 70.0% (35/50) after the 1st, 2nd and 3rd sessions of treatment in Xunjingcuiqi group, respectively; and those were 38.0% (19/50), 44.0% (22/50) and 46.0% (23/50) in the routine acupuncture group, respectively. The differences were significant in the 1st and 3rd sessions of treatment between the two groups (both P < 0.05).

CONCLUSIONXunjingcuiqi needling technique combined with routine acupuncture achieves the apparent superior efficacy on acroparalysis induced by ischemic stroke as compared with the simple routine acupuncture. Xunjingcuiqi needling technique obviously improves muscle strength and shortens the duration of sickness.

Lycii Cortex, a popular herb medicine in traditional Chinese medicine, is used to treat different inflammation-related diseases. The aim of our work is to find the key constituents inhibiting NF-kappaB, a key regulator of inflammation. In the investigations of cell-based in vitro assays of extracts, we found that both ethyl acetate extract and methanol extract of Lycii Cortex inhibited the TNF-alpha-induced activation of NF-kappaB. Through bioassay-guided fractionation, we identified 4 phenolic amides including trans-N-(p-coumaroyl) tyramine (1), trans-N-feruloyltyramine (2), trans-N-caffeoyltyramine (3), and dihydro-N-caffeoyltyramine (4). Four phenolic amides showed differently inhibitory activities on TNF-alpha-induced NF-kappaB activation. Trans-N-caffeoyltyramine (3) was identified as the key component with an IC50 of 18.41 micromol x L(-1). It was suggested that the hydroxyl group at C-3 in trans-N-caffeoyltyramine might be a key binding site and its C-7,8-double bond might play an important role on NF-kappaB inhibitory activities as the link of the conjugation of pi electrons leading to a partial planar conformation. It might be inferred that the biological activity of compound 3 is attributed to the structure of Michael reaction acceptor containing alpha, beta-unsaturated ketones and benzene along with hydroxyl group in o-diphenol.

Xuefu Zhuyu decoction (XFZYD) is a famous traditional Chinese medicine (TCM) formula, is widely used in the treatment of cardiovascular and cerebrovascular diseases in China over one hundred years. But its effect on antioxidant and drug-metabolizing enzymes are unknown. This study was to observe the effects of Xuefu Zhuyu decoction (XFZYD) on the activities of antioxidant and drug metabolism enzymes (DMEs) in liver of rats. Male SD rats, treated with XFZYD at the dosage of 3.51, 7.02 and 14.04 g x kg(-1) per day for 15 days, serum were collected, tissue fluid, cytosols and microsomes isolated from liver tissues were prepared by centrifugation according to the standard procedure, the activities of antioxidant enzymes and drug-Metabolizing Enzymes were determined by UV-V is spectrophotometer. In serum, the activities of AST was not significantly affected by the treatment with XFZYD, at the high- est dose, the levels of ALT, Cr and BUN were significantly decreased (P < 0.05). GPX were significantly increased at the dose of 7.02, 14.04 g x kg(-1) (P < 0.05), CAT were significantly increased at the highest dose (P < 0.05). T-SOD was not significantly af- fected by this treatment. In the liver tissue, GPX was significantly increased at the dose of 3.51, 7.02 g x kg(-1) (P < 0.05), GST, CAT and T-SOD were not significantly affected following this treatment. In cytosols, GST was significantly increased at the dose of 3.51 g x kg(-1) (P < 0.05), T-SOD was remarkable induced at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05). In microsomes, XFZYD had no significant effect on Cytochromeb5, NADPH-Cytochrome P450 reductase, CYP3A, CYP2E1 and UGT, XFZYD significantly in- duced GST at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05), and the level of GSH were significantly increased by XFZYD at the dose of 3.51, 7.02 and 14.04 g kg(-1) (P < 0.05). These findings suggest XFZYD can induce the activities of GPX, CAT, SOD, GST and increase GSH level in liver of rats, which indicate XFZYD may have detoxification and antioxidant functions.
