Bupleurum chinense used in the study were cultivated in the experimental fields of Gansu agricultural University for three years. The seeds of B. chinense were collected every 3 days 10 d after the blossom. The result showed that the 1 000-grain fresh weight reached the maximum 43 d after the blossom and then decreased rapidly, at the mature period the fresh weight of seeds were falling to the same level of the dry weight. The dynamic change of the grain dry matter accumulation showed as an S-shape curve, the rapid increase stage was 25-34 d following the flower, and the grain filling was ended 46 d after blossom. Grain filling rate was under the law "fast-slow-fast-slow". And there were two peaks of grain filling rate appeared, after reached the second peak 28 d after the flower the filling rate decreased rapidly and stayed steadily 43 d after flowering. The dehydration rate was also measured at its maximum 43 d following flower. The indexes of seeds all reached the top 52 days following the blossom, when the germination rate reached the peak (34.33%) and water content of seeds was near 10%. The rate of germination and the 1 000-graid weight of seed showed significant positive correlation, while the water content of seeds was found significant negatively correlation with germination percentage. So the best time for harvest should be 52 d after flowering (9 month), the seeds collected at that time showed both high quality and germination rate.

Objective To establish the ischemic precondition ([PC) model of PC12 cell line in vitro, and to explore the effect of nitric oxide (NO) on the IPC cerebral protection. Method PC12 cells were cultured and used for producing the model of ischemie precondition by the way of oxygen-glucose deprivation. Twenty dishes of cells were randomly divided into four groups (5 dishes for each group): control group, ischemic precondition group (IPC),non-ischemic precondition group (NIPC) and L-NAME treatment group (L-NAME). In control group, the cells were in-cubated with low glucose (<1 g/L) and2% FBS medium in normal oxygen; in IPC group, the cells were administrated with oxygen-glucose deprivation (OGD) for 6 hours, and then subjected with reperfuaion before OGD 15 hours; in NIPC group, the cells were treated the same as control group for 6 hours, and then subjected with reperfusion before OGD 15 hours; in L-NAME group, the cells received L-NAME (1 mmol/L) and cocultured for 30 minutes before OGD 6 hours, and then received the same treatment as the IPC group. To test whether the model was established, metabolic rate of MIT, LDH release were measured and the apoptosis rate was detected by flow cytometry following oxygen-glucose deprivation 15 hours. The activity of nitric oxide synthases (NOS) was as-sessed by biochemical assay. One-way ANOVA and LSD multiple comparison test were used to analyze differences among different groups, and P<0.05 was considered different. Results Compared with NIPC group, the metabolic rate of MTT increased (94.9%±35.1%, P<0.05), while LDH release and the cell apoptotic rate decreased significantly in IPC group (279.1%±28.1%, P<0.03). Compared with control group(100.0%± 13.5%),the activities of NOS increased both in NIPC and IPC groups (390.0%±14.6%, P<0.01;126.3% ±10.6%, P<0.01). Moreover, the apoptosis rates in each group (control group, IPC group, NIPC group and L-NAME group) were 5.90, 8.73, 38.62 and 11.73%,respectively. Conclusions IPC reduces the death and apoptosis rate of PC12 cell after oxygen-glucose deprivation injury. NO might be involved, but it is not the only factor.

Objective To investigate rite effects of loag-term exposure to low-level sevoflurane on reproductive function in mice.Method F0ny male ICR mice,aged 60 d,weighlag 20-25 g,were randomly divided into 4 groups(n=10 each):control group received no sevoflunme(C);group S1-3 were exposed to 0.003%.0.01% and 0.03% sevoflurane 2 h per day for 5 consecutive days per week for 8 weeks respectively. The mice were then sacrificed at the end of the 8 weeks.The testes and epididymis were emoved and sampled for determination of the activities of total lactic dehydregenase(LDH)and lactic dehydrogenase-X(LDH-X),and the motility rate,amount,and aberration rate of sperm.Testicular uhrastructure were observed by transmission electron microscopy.Results The sperm motifity nne were significantly lower.the sperm aberration rate higher and the activity of LDH-X lower in group S3 than in group C(P<0.05),but there was no significant difference in the above parametem between group SI and group S2(P>0.05).The pathology changed of testes occurred only in group S3 among the 3 groups.Conclusion Long-term exposure to 0.03% sevoflurane can result in the abnormality of the reproductive function in male mice but exposure to≤0.01%sevoflurane dose not.

OBJECTIVE To investigate the protective effects and mechanism of diterpene ginkgolides meglumine injection (DGMI) against oxidative stress induced by oxygen-glucose deprivation (OGD) in SH-SY5Y cells. METHODS SH-SY5Y cells were divided into five groups: normal control, model control (OGD group) and drug(25 mg · L- 1) administration groups including DGMI group, extract of ginkgo biloba leaves injection group (EGBLI) and lactones ginkgo biloba injection group (LGBI). The cells suffered from oxygen-glucose deprivation (OGD) for 4 h, followed by reoxygenation with drugs for 6 h. Then, cell viabilities were detect using CCK-8 assays, reactive oxygen species (ROS) levels using fluorescence probe DCFH-DA and superoxide dismutase (SOD) activities using WST-1 test. Western blotting was used to detected protein levels of hemeoxygenase-1(HO-1), NAD(P)H, quinone oxidore?ductase l (Nqo1), protein kinase B (Akt), phosphorylated Akt (p-Akt), nuclear factor-E2-related factor2 (Nrf2) and phosphorylated Nrf2 (p-Nrf2). The cells were induced by OGD for 4 h, followed by reoxygen?ation and DGMI for 1 h, combined with different concentrations of PI3K inhibitor (LY294002) (at the final concentration of 12.5, 25 and 50 μmol · L-1) before the protein levels of AKT, p-AKT, Nrf2 and p-Nrf2 were detected by Western blotting. RESULTS SH-SY5Y cells induced by OGD for 4 h resulted in an increase in ROS(P<0.01), but a decrease in cell viabilities(P<0.01), SOD activities(P<0.01), and antioxidant protein levels ( Akt, p-Akt, Nrf2, p-Nrf2, HO-1 and Nqo1) (P<0.01). Compared with OGD group, treatment with reoxygenation and drugs (DGMI,EGBLI and LGBI respectively) for 6 h resulted in a decrease in ROS (P<0.01), but an increase in cell viabilities, SOD activities and antioxidant protein levels of p-Nrf2, HO-1, Nqo1 and p-Akt(P<0.05,P<0.01). DGMI group showed the best efficiently. Moreover, after OGD for 4 h, compared with DGMI group, combining reoxygenation and DGMI with LY294002 for 1 h resulted in a concentration-dependent inhibition of the protein levels of p-AKT and p-Nrf2(P<0.01). CONCLUSION DGMI 25 mg · L-1 can inhibit oxidative stress in SH-SY5Y cells induced by OGD by increasing the activity and expression of Nrf2 through PI3K/Akt pathway, which may be one of the mechanisms by which DGMI protects neurons from stroke.

The paper aimed to evaluate the effects of lead stress on photosynthetic performance and ginsenoside content in ginseng (Panax ginseng). To accomplish this, three years old ginseng were cultivated in pot and in phytotron with different concentrations of lead, ranging from 0 to 1000 mg x kg(-1) soil for a whole growth period (about 150 days). The photosynthetic parameters in leaves and ginsenoside content in roots of ginseng were determined in green fruit stage and before withering stage, respectively. In comparison with the control, net photosynthetic rate and SPAD value in ginseng leaves cultivated with 100 and 250 mg x kg(-1) of lead changed insignificantly, however, ginseng supplied with 500 and 1 000 mg x kg(-1) of lead showed a noticeably decline in the net rate of photosynthesis and SPAD value (P < 0.05), the lowest net photosynthetic rate and SPAD value showed in the treatment supplied with 1 000 mg x kg(-1) of lead, with decline of 57.8%,11.0%, respectively. Total content of ginsenoside in ginseng roots cultivated with 100 mg x kg(-1) of lead showed insignificantly change compared to the control, but the content increased remarkably in treatments supplied with 250, 500, 1 000 mg x kg(-1) of lead (P < 0.05), and highest content appeared in these ginsengs exposed to 1000 mg x kg(-1) of lead. The net photosynthetic rate and SPAD value in leaves of ginseng both showed significantly negative linear correlations with lead stress level (P < 0.01), and significant positive linear correlations between total content of ginsenoside and lead concentration was also observed (P < 0.05). These results strongly indicate that exposing to high level of lead negatively affects photosynthetic performance in ginseng leaves, but benefits for accumulation of secondary metabolism (total content of ginsenoside) in ginseng root.
