To obtain ginsenoside Rg1 molecularly imprinted polymer (MIP) separating materials with high selectivity, enrichment and adsorption performance through directional separation of ginsenoside Rg1 and analogues. In this study, MIPs were respectively prepared by precipitation polymerization and surface imprinted polymerization. Their adsorption performances were compared. The results showed that ginsenoside Rg1 MIPs prepared by the above two methods had a high adsorption performance to template molecules, with the maximum apparent adsorbing capacity of up to 27.74, 46. 80 mg x g(-1), respectively. Moreover, MIPs prepared by surface imprinted polymerization showed higher adsorption capacity than that by precipitation polymerization. The experimental results indicated that as for ginsenoside Rg1 with higher polarity, MIPs prepared by surface imprinted polymerization showed higher selectivity and adsorption performance, which provides provide important reference for preparing imprinted polymers with good adsorption performance with active molecules with strong polarity.

Aim To evaluate the estrogen-like activity of Semen Descurainiae aqueous extracts (SD-ae), to deter-mine its effective chemical separation components and to study the mechanisms. Methods The estrogen-like ac-tivity of SD-ae and its effective chemical separation com-ponents were evaluated by the animal experiment, uterine weight test and cell experiment, namely E-SCREEN ex-periment. Estrogen receptor antagonist ICI182,780 inter-vention blocking experiment was carried out to detect the pathway of estrogen-like action; the HEK293 cells were co-transfected with the report gene carrier and the ERα, ERβ expression vector by cationic liposome, the report gene carrier was constructed via the estrogen-responsive component (ERE) and the report gene luciferase (Luc), then the estrogen-like signaling pathway was evaluated with standardized Luc activity; the expression of estrogen receptor ERα, ERβ and estrogen-induced gene PR mR-NA was detected by real-time fluorescence quantitative PCR. Results Compared with normal control, SD-ae low and high dose could significantly improve the uterine coefficient of immature female mice(P<0.05), and the oligosaccharides composition of Semen Descurainiae aque-ous extracts(SD-ae-Oli) and the polysaccharide composi-tion of Semen Descurainiae aqueous extracts(SD-ae-Pol) also significantly improved the uterine coefficient of im-mature female mice (P<0.01 or P<0.05); SD-ae, SD-ae-Oli and SD-ae-Pol had a significant proliferative effect on MCF-7 cells ( P <0.01 or P <0.05), while ICI182,780 intervened to block its proliferative effect. The reporter gene technology showed that the standardized Luc activities of SD-ae, SD-ae-Oli and SD-ae-Pol were significantly higher than those of the normal control when they were induced by ERβ respectively (P<0.01); and the SD-ae significantly increased the expression of ERβ mRNA in mouse uterus than the normal control, but no effect was found on the expression of ERα and PR mR- NA. Conclusions The estrogenic effect of SD-ae may be found at the first time, and its effective chemical sepa-ration components are SD-ae-Oli and SD-ae-Pol. Their estrogenic effects are mediated by ERβ. The molecular mechanism of the estrogenic effects is probably that SD-ae promotes the expression of ERβ mRNA.

In this paper, GLUT4 vesicles are observed in real-time under TIRF microscopy and a new three-dimensional single particle tracking algorithm according to the unique features of TIRF is put forward. Firstly a fluorescence correction procedure was processed to solve the problem of fluorescence bleaching over time and mobile vesicles were segmented by an adaptive background subtraction method. Kalman filtering was then introduced to track the granules so as to reduce the searching range and to avoid the disturbance of background noise and false targets. In the experiments the algorithm was applied in analyzing the long-distance movement of GLUT4 vesicles. The experimental results indicate that the algorithm has achieved robust tracking of the vesicles in the imaging plane and has effectively calculated the position in the direction orthogonal to the imaging plane.

OBJECTIVETo explore the therapeutic efficacy of combination of Compound Xuanju Capsule (CXC) and clomiphene citrate (CC) for ovulatory dysfunctional infertility (001) patients of Shen-yang deficiency syndrome (SYDS).
METHODSTotally 87 001 patients of SYDS were randomly assigned to 2 groups, the treatment group (44 cases, treated with CXC and CC) and the control group (43 cases, treated with CC alone). The post-treatment clinical symptoms, the cervical mucus, the endometrial thickness, the quality of follicles, the ovulation, and the pregnancy rate, and so on were observed.
RESULTSIn aspect of improving the patients' SYDS, the effective rate was 86.4% (38/44) in the treatment group and 25.6% (11/43) in the control group. It was better in the treatment group (P < 0.01). After treatment better effects on the cervical mucus, the endometrial thickness, and the pregnancy rate were obtained in the treatment group, showing statistical difference when compared with the control group (P < 0.05). There was no statistical difference in the rate of ovulation and mature follicular numbers between the two groups (P > 0.05).
CONCLUSIONCXC combined CC could ameliorate hypoestrinemia-like effects on the endometrium, increase the endometrial thickness, and be favorable to the pregnancy in treating ODI patients of SYDS.

The study was aimed to investigate the expression of Notch signal molecules in human lymphoma cells and its significance. Raji, Maver, Z138 and Jurkat cell lines were used in the study. RT-PCR was used to determine the expression of Notch signaling molecules in these lymphoma cells. Flow cytometry was used to detect the apoptosis and cell-cycle of the lymphoma cells induced by different concentrations of gamma secretase inhibitor DAPT. CCK-8 was used to detect the proliferation of the lymphoma cells treated by DAPT. The results showed that the expression of Notch molecules in the four cell lines was different. Notch1 and Notch2 were found to be expressed in the four lymphoma cell lines, Notch3 predominantly expressed in Jurkat cells, Notch4 only expressed in Raji cells weakly and Hes1 only expressed in Raji and Jurkat cells. Treatment with DAPT could increase the apoptosis ratio of Raji and Jurkat cells. Besides, DAPT could significantly inhibit the proliferation of Raji and Jurkat cells by inducing the cell cycle arrest in G(1) phase, but the effect of DAPT on Maver and Z138 cells was not obvious. The activity of Notch pathway could be inhibited by DAPT treatment through down-regulating the expression of Notch target gene Hes1. It is concluded that the abnormal expression and activation of Notch signal pathway play an important role in the proliferation of lymphoma cells. Notch may be likely a new target for the therapy of lymphoma.
