Objective: To study the effect and mechanism of Rhodobryum giganteum (Schwaegr.) Par. 's anti-atherosclerotic effect. Methods:Vascular endothelial ceils were cultivated and the H2O2 were used to induce the oxidative stress injury of human umbilical vascular endothelial cells (HUVEC). Water extract of Rhodobryum giganteum (Schwaegr.) Par. Was added to cultivated HUVEC, and the activity of the cells was carefully determined by OD value with MTF method. The Griess Reagent was used to detect the NO concentration of different groups. At the same time, the NO fluorescence analysis probe, DAF-FM DA. (3-amino, 4-aminomethyl-2', 7'-difluorescein, diacetate), was used to determine the activity of NO synthase. Results:The most suitable stimulating concentration of H2O2 on HUVEC is 12.5 mmol· L-1. Water extract of Rhodobryum giganteum (Schwaegr.) Par. Was co-cultured with HUVEC damaged byH2O2 .The OD values indicate that 3.33,2.50 mg· mL-1 water extract groups increase activity of the cells significantly compared with the model group (P <0.05) ,and 3.33 mg·mL-1 is much better than 2.50 mg·mL-1 dose group. To determine the content of NO and NOS, the 2.50 mg·mL-1 dose has significant effect (P < 0.05). Conclusions: The H2O2 concentration of 12.5 mmol· L-1 could be used to establish the injured model of endothelial cell successfully. 2.50 and 3.33 mg·mL-1 water extract of Rhodobryum giganteum (Schwaegr.) Par. Have protective effect on ECV304 injured by H2O2. 2.50 mg· mL-1 water extract of Rhodobryurn giganteum (Schw aegr.) Par could increase the activity of NOS and promote the synthesis and secretion of NO.

Objective To study the effect of red cell and plasma protein parameters on progression, prognosis and recurrence of cerebral infarction. Methods Clinical data from 105 patients with cerebral infarction were analyzed. The pa?tients were divided into four paired groups:progressive stroke group and complete stroke group, short-term favorable progno?sis group and short-term unfavorable prognosis group, long-term favorable prognosis group and long-term unfavorable prog?nosis group, relapsed cerebral infarction group and not relapsed group by different criterion. The red cell and plasma protein parameters were compared between groups. Results There were significantly higher mean corpuscular volume(fL:85.92± 4.50 vs 83.79±4.64,t=2.164,P<0.05), red cell distribution width(fL:13.50±2.45 vs 11.90±2.90,t=2.694,P<0.01), globu?lin(g/L:27.46±4.33 vs 24.79±4.03,t=3.029,P<0.01)and lower albumin(g/L:39.00±3.86 vs 42.89±4.45,t=4.242,P<0.01)in progressive stroke group than those of complete stroke group. The elevated red cell distribution width, reduced albu?min were the risk factors of progressive stroke. In the short-term unfavorable prognosis group, red cell distribution width was significantly higher than that in short-term favorable prognosis group(fL:13.90 ± 2.45 vs 12.00 ± 2.12,t=2.905,P<0.01). The red cell distribution width was positively correlated with mRS scores assessed 3 months and 18 months after cerebral in?farction(P<0.01). Conclusion Progressive stroke rate increases in cerebral infarction patients with elevated red cell distri?bution and reduced albumin;Red cell distribution width has a certain reference value for forecasting the prognosis of cere?bral infarction .

OBJECTIVETo study the mechanism of reversal effect of Curcuma Wenyujin n-Butyl alcohol extract (CWNAE) on multiple drugs resistance (MDR) of SGC7901/VCR cells.
METHODSSGC7901/VCR cells were co-culured with different concentrations CWNAE (80, 40, and 20 μg/mL) and Verapamil (VP, 10 μg/mL) for 24 h, and then acted with Adriamycin (ADM) for 1, 2, and 4 h, respec- tively. SGC7901/VCR cells with no intervention were taken as the vehicle control group. SGC7901/VCR cells treated with ADM alone were taken as the control group. The effect of CWNAE on intracellular ADM concentration was detected by flow cytometry (FCM). Cells were treated as mentioned before without any intervention of ADM. SGC7901/VCR with no ADM intervention were taken as the control group. The effect of CWNAE on the expression of P-glycoprotein (P-gp), lung resistance protein (LRP), and glu- cosylceramide synthase (GCS) was studied by Western blot. The effect of CWNAE on the location and expression quantity of P-gp was further illustrated by immunohistochemistry (IHC).
RESULTSCompared with the ADM group, the expression ratio obviously increased in the W80, W40, W20, and VP10 groups with statistical difference (all P < 0.05). The comparative expression quantity of P-gp, GCS, and LRP in SGC7901/VCR cells was obviously higher than that of non-MDR with statistical difference (all P < 0.05). The expression quantity of P-gp and GCS could be obviously down-regulated by 80 and 40 μg/mL CWN- AE, and 10 μg/mL VP, with no effect on the expression of LRP. Results of IHC proved that P-gp was mainly expressed on the cytomembrane or in the plasma, and it was also expressed on the nuclear membrane. P-gp in different locations could all be down-regulated by CWNAE.
CONCLUSIONSCWNAE could reverse the MDR of SGC7901/VCR cell line probably by inhibiting the expression of P-gp and GCS. CWNAE had no effect on LRP that also highly expressed on SGC7901/VCR. So we supposed that CWNAE could become a potential drug to reverse MDR of highly expressed P-gp and GCS.

This study was aimed to establish a method for the rapid content determination of Ixerin Z and 11,13α-dihydroixerin Z in Ku-Die-Zi (KDZ) injection by UPLC-ESI-MS/MS. The separation was performed on a Waters ACQUITY BEH C18 column (2.1 mm × 50 mm, 1.7μm) by using a gradient elution with the mobile phase of acetonitrile-water at the flow rate of 0.4 mL·min-1. The column temperature was set at 40℃. Multi-reaction moni-toring (MRM) scanning was employed for quantification in ESI negative mode. The results showed that two sesquit-erpene lactones in KDZ injection were totally separated within 2 min. The linear range of Ixerin Z was 5.70-182.50 ng·mL-1, and the linear range of 11,13α-dihydroixerin Z was 4.60-131.25 ng·mL-1. The correlation coefficient r was more than 0.999 0. The recovery rates (n = 6) were 98.18% and 97.52%, with RSDs < 1.5%. The established method was successfully applied for simultaneous content determination of Ixerin Z and 11,13α-dihydroixerin Z in 6 batches of KDZ injection from 2 factories, which had some variations on the content determination results. It was concluded that the method was rapid, accurate and sensitive, which can be used for the content determination of two sesquiterpene lactones in KDZ injection.
