Ginsenosides are the abundant secondary metabolites in American ginseng (Panax quinquefolium), it could be released into soil through root exudation and decomposition during plant growth. This study determined ginsenoside contents in American ginseng cultivated soil by HPLC. Three ginsenosides, Rb1, Rb2 and Rd, were detected in the rhizosphere soil of 3-4 years old American ginseng cultivated in Huairou District, Beijing, and their contents were 0.80-3.19 mg x kg(-1). Correspondingly, the contents of the three ginsenosides in soil solution were 4-16 mg x L(-1) at field water-holding capacity of 20%. According to the field soil test data, we designed the concentration of ginsenosides for bioassays (0.2-125 mg x L(-1) in solution or 0.2-125 mg x kg(-1) in soil). The results showed that radicle lengths of American ginseng were reduced by 6%-23% in solution containing 0.2-125 mg x L(-1) ginsenoside extract, and a significant difference was observed at concentration of 125 mg x L(-1) (P < 0.05). The shoot lengths of American ginseng were not significantly inhibited by 0.2-125 mg x L(-1) ginsenosides extractions. After 20 days of growth in nutrient solution amended with 25 mg x L(-1) ginsenosides extraction, plant height of 3-year-old American ginseng seedling was decreased by 28% compared to the control, and the biomass of aerial parts was also reduced by 50% (P < 0.05). However, the growth of newly-grown fibrous root was not significantly inhibited. Comparatively, when American ginseng embryos were cultivated into sterile or non-sterile soil, neither radicle lengths nor shoot lengths were significantly affected by 0.2-125 mg x kg(-1) ginsenoside extracts. In conclusion, ginsenosides showed autotoxic effect on growth of American ginseng radicle and adult seedling, however, this effect was weakened in field soil.

OBJECTIVETo explore the difference in the efficacy and effect mechanism of subcortical ischemic vascular disease (SIVD) complicated with depression between acupuncture and medication.

METHODSSixty patients were randomized-into an acupuncture group and a medication group, 30 cases in each one. In the acupuncture group, acupuncture was applied to Baihui (GV 20), Shuigou (GV 26), Fengfu (GV 16), Fengchi (GB 20) and the others, once a day, 6 times a week. The treatment of 4 weeks made one session and totally 2 sessions were required. In the medication group, nimodipine 30 mg, three times a day and fluoxetine 20 mg, once a day were prescribed for oral administration, for 8 weeks totally. Before treatment, at the end of the 4th week and at the end of the 8th week of treatment, cerebral blood flow velocity (CBFV) and solubility CD40 ligand (sCD40L) were determined respectively. The scores in Montreal cognitive assessment (MoCA) and Hamilton' s depression scale (HAMD) were evaluated in the two groups. The efficacies on cognitive function and depression symptoms were compared in the patients between the two groups. Results Compared with the outcome before treatment, mean blood flow velocity (Vm) of middle cerebral artery (MCA), anterior cerebral artery (ACA) and posterior cerebral artery (PCA) was increased significantly at the end of the 4th week of treatment in the two groups (all P<0.05). At the end of the 8th week, Vm was increased much significantly (all P<0.01). The differences were not significant in comparison between the two groups (all P>0.05). Compared with the expression before treatment, sCD40L was reduced significantly after treatment in the patients of the two groups (all P<0.01), but the differ- ence was not significant between the two groups (all P>0.05). Compared with that before treatment, MoCA score was increased significantly after treatment in the two groups (all P<0.01), HAMD score was reduced sig- nificantly (all P<0.01), the differences were not significant in comparison between the two groups (all P>0.05). The total effective rate of cognitive improvement was 86.7% (26/30) in the acupuncture group and was 80.0% (24/30) in the medication group, the differences were not significant in comparison of the two groups (P>0.05). The total effective rate of the improvement in depression was 93.3% (21/30) in the acupuncture group and was 86.7% (26/30) in the medication group, the differences were not significant in comparison of the two groups (P>0.05).

CONCLUSIONAcupuncture could significantly increases CBFV and reduces serum sCD40L expressions in the patients of SIVD complicated with depression, and significantly improves cognitive function and relieves depression symptoms. The efficacy of it is similar to that of western medication. The increase of serum sCD40L expression is possibly involved in the occurrence and development of SIVD. Reducing sCD40L expression contributes to the alleviation of damage induced by cerebral ischemia and reperfusion.

OBJECTIVETo explore the effect of Jingui Shenqi pill (JGSQP) with various concentrations at different time points on pituitary adrencorticotropic hormone (ACTH) gene expression level in Shen-Yang deficiency rats.

METHODSThe Shen-Yang deficiency rats were randomly divided into the model control group and the high, medium and low dosage of JGSQP groups. Reverse transcriptase polymerase chain reaction was used to observe the effect of JGSQP on the ACTH mRNA of pituitary tissue in rats treated at different time points (10 d, 20 d, 30 d).

RESULTSAs compared with that in the model group, the ACTH gene expression level was significantly higher in the high dose JGSQP group (P < 0.05), and the increment in the medium dosage group was significantly higher in comparing with that in the high and low dosage groups (P < 0.05 or P < 0.01).

CONCLUSIONThrough up-regulation on ACTH gene expression is possibly one of the mechanisms of JGSQP in treating Shen-Yang deficiency.

The present study is to elucidate the mechanisms underlying Gleevec-induced apoptosis of chronic myeloid leukemia (CML) K562 cells in vitro. The apoptotic cell death and cell cycle distribution after Gleevec treatment and the effect of PDCD4 siRNA on Gleevec-induced apoptosis of K562 cells were analyzed by flow cytometry. The effect of Gleevec on p-Crkl, caspase-3, PARP and PDCD4 protein levels, and the knockdown efficacy of PDCD4 siRNA were detected by Western blotting. The results showed that Gleevec dramatically suppressed the phosphorylation level of Crkl in a dose-dependent manner and induced significant apoptosis and G0/G1 cell cycle arrest of K562 cells in time- and dose-dependent manners. In addition, Gleevec activated caspase-3 and its downstream substrates PARP, and the caspase pan inhibitor Z-VAD-FMK (50 micromol x L(-1)) markedly reduced Gleevec-induced apoptosis from 47.97% +/- 10.56% to 31.05% +/- 9.206% (P < 0.05). Moreover, Gleevec significantly increased the protein expression of programmed cell death 4 (PDCD4). PDCD4 knockdown by siRNA reduced Gleevec-induced apoptosis from 46.97% +/- 14.32% to 42.8% +/- 11.43%. In summary, Gleevec induced apoptosis in K562 cells via caspase-3 activation.

· AIM: To investigate the role of intercellular adhesion molecule-1 (ICAM-1) in the graft rejection of rabbit penetrating keratoplasty (PKP).· METHODS: Sutures were used to produce corneal neovascularization (CNV) on New Zealand white rabbits to make PKP model. Graft mean survival time and rejection index were determined. The levels of sICAM-1 in serum and aqueous humor were dynamically determined by enzyme-linked immunosorbent assay (ELISA).Immunohistochemical technique was used on cornea to get the evidence of expression and distribution of ICAM-1.· RESULTS: Graft mean survival time is (12.4±1.3) days.The mean sICAM-1 levels in aqueous humor and serum in the control animals that did not undergo surgery were (16.6±3.6)ng/L and (95.2±6.3) ng/L respectively. Levels in aqueous humor and serum for the graft rejection group increased postoperatively, continued to increase to (53.9±19.2)ng/Land (378.8±30.6)ng/L, compared to those in the other group (P ＜0.01). ICAM-1 positive cells were found in the graft rejection group.· CONCLUSION: ICAM-1 plays a critical role in initiating and maintaining corneal graft rejection. Sequential determination of serum sICAM-1 after operation may be of value in the prediction and diagnosis of acute rejection.
