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.

OBJECTIVETo compare therapeutic effects of acupuncture and embedding thread on depression and to probe the mechanism.

METHODSThirty-two adult SD rats, 16 females and 16 males, were randomly divided into a normal group, a model group, an acupuncture group and an embedding thread group, 8 rats in each group. Separated feeding, long-term unpredictable and middle stimulation stress were used for development of depression rat model. At the same time, the treatment groups were treated for 21 days. The changes of norepinephrine (NE), 5-hydoxytryptamine (5-HT) and dopamine (DA) contents in the brain were detected by high performance liquid chromatography-electrochemical detector.

RESULTSCompared with the normal group, 5-HT, NE and DA contents in the hypothalamus and hippocampus decreased significantly in the model group (P < 0.05, P < 0.01); compared with the model group, the contents of the central monoamine neurotransmitters increased in both the acupuncture group and the embedding thread group, but the embedding thread group had more obvious action in improvement of 5-HT and DA levels in the hypothalamus and DA level in the hippocampus than the acupuncture group with no significant difference between the two groups.

CONCLUSIONBoth acupuncture and embedding thread therapy are effective for the depression model rat. They play the therapeutic role through regulating central monoamine neurotransmitters.

OBJECTIVETo investigate the effects of hydroquinone (HQ) on expression of topoisomerase IIα (TOPOIIα) in human bone marrow mononuclear cells, and to explore the role and possible regulatory mechanism of TOPOIIα involved in toxicity of HQ to hematopoietic cells.

METHODSAfter human bone marrow mononuclear cells were exposed to 50 µmol/L HQ (used the cells which were exposed to sterile distilled water as control); the activity of TOPOII was measured by TOPOII assay kit; the expression levels of TOPOIIα mRNA and protein were detected by RT-PCR technique and Western blotting method respectively; the chromatin immunoprecipitation (ChIP) assay was carried out to study the possible mechanism of TOPOIIα expression changes.

RESULTS(1) The activity of TOPOII was inhibited obviously; the protein and mRNA expression of TOPOIIα were 0.017 ± 0.029 and 0.610 ± 0.128, significantly lower than that in the control with the significant difference (P < 0.01) after treated with HQ for 10 h; (2) The decreased content of TOPOIIα was associated with descended level of histone H4 acetylation than in the control, from 1.198 ± 0.056 to 0.324 ± 0.229, with the significant difference (P < 0.01), without accompanied descended level of histone H3 acetylation, from 1.253 ± 0.045 to 1.177 ± 0.025 (P > 0.05); (3) TOPOIIα mRNA expression decreased gradually after HQ processing, and the chemical modification (histone H4 acetylation) of TOPOIIα promoter happened prior to the mRNA expression.

CONCLUSIONHQ could repress the expression of TOPOIIα in human bone marrow mononuclear cells; the change of histone chemical modification plays an important role in the benzene's hematopoietic toxicity.

OBJECTIVETo provide reliable evidence of "J in three-needle therapy" for treatment of stroke.

METHODSMulti-central randomized controlled trials were adopted, 180 hemiplegia patients of ischemic stroke were randomly divided into a fin three-needle group (90 cases) and a routine acupuncture group (90 cases). Two groups were both treated with basic neurology therapies, and J in three-needle group was treated with J in three-needle therapy, three acupoints of tempora, hand and foot etc. were selected; the routine acupuncture group was treated with traditional acupuncture, Quchi (LI 11), Huantiao (GB 30), Futu (ST 32) etc. were selected. Both groups were treated with acupuncture for 5 weeks. The cognitive function score of functional comprehensive assessment scale (FCA), the scores of mini-mental state examination scale (MMSE) and modified Barthel index (BI) were compared before and after treatment between two groups. Results After treatment, the scores of FCA, MMSE and BI in both groups were significantly improved compared to those before treatment (P < 0.01, P < 0.05); the improvement of FCA score, MMSE score and BI score in the J in three-needle group were superior to those of the routine acupuncture group after treatment (P < 0.01, P < 0.05). The total effective rate of 85.4% in the J in three-needle group was superior to tohat of 70.0% in the routine acupuncture group (P < 0.05).

CONCLUSIONJ in three-needle acupuncture treatment can obviously improve the cognitive function and activity ability of daily life of hemiplegia patients after stroke, and the therapeutic effect of J in three-needle therapy is superior to that of traditional acupuncture treatment.
