RESUMO

The acquisition and storage of the image data are important in the Chinese medicine resources survey, and it is important data and evidence for the process and the results. The image data of the Chinese medicinal materials' habitat, original plant or animal, processing in habitat, commodity form, the relative contents and workshop scenarios in the investigation are important for the compiling of the Color Atlas of National Chinese Medicine Resources, mapping the digital scattergram of the Chinese medicine resources, establishing the digital Chinese medicine plant herbarium and acquiring the documentary of the Chinese medicine resource survey. The content, procedures and methods of the video data collecting have been related and analyzed in this article to provide reference for the Chinese medicine resources survey.

RESUMO

This research aimed at studying the effects of irrigation and rhizome length on the survival of ratio, yield and quality of Glycyrrhiza uralensis in wild tending condition. Employed the split-block design to carry out the field experiment, sampled with the quadrat method to measured the relative growth indexes and to estimate the yield, used the HPLC (high performance liquid chromatog- raphy ) method to measure the glycyrrhizin in the rhizome and adventitious root of the G. uralensis in this study. The quantity of the adventitious roots and the survival ratio were increased significantly as the length of the rhizome increased (P < 0.01), but the length of the rhizome had no remarkable effect on the content of glycyrrhizin. The average content of the glycyrrhizin in the adventitious root and rhizome could reach 3.03% and 2.12% after 3-year wild tending, respectively, and this results indicated that the quality of the glycyrrhiza using this method was much better than that from cultured glycyrrhiza with the reproducing method of seeding. so using the rhizome as reproductive material to produce the glycyrrhiza under the wild tending condition could get the high quality glycyrrhiza quick- ly and steadily, this phenomenon could be explained by the Hypothesis of synthetic inertia of the medicinal components from the wild material of G. uralensis. But the maximum yield with this method was just more than 945 kg x hm(-2) in this study. So the further work of how to increase the yield in the practical application with the method found in this study need to be done in the next research.

RESUMO

BACKGROUND: Females with acute myocardial infarction (AMI) have a higher risk of adverse outcomes because of receiving less evidence-based medical care. Our aim was to investigate the gender disparity in early death after ST-elevation myocardial infarction (STEMI) in the current era. METHODS: A total of 1429 consecutive patients with STEMI in the Liaoning district were analyzed. We compared hospital care and cardiac event data by sex for in-patients with acute STEMI within 24 hours of symptom onset. RESULTS: In the emergency reperfusion group (n = 754), in-hospital mortality occurred in 4.2% of the males and 11.2% of the females (P = 0.001). In the non-emergency reperfusion group (n = 675), in-hospital mortality occurred in 13.0% of the males and 22.9% of the females (P = 0.001). Multivariate Logistic regression analysis revealed female sex as an independent risk factor of death for STEMI patients during hospitalization (OR = 1.691, P = 0.007). After controlling for patients who died within 24 hr after admission, female sex was no longer an independent risk factor (OR = 1.409, P = 0.259). CONCLUSION: Female sex was an independent risk factor for in-hospital mortality of STEMI patients, which is explained by an excess of very early deaths.

RESUMO

Apoptosis induced by tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) can be regulated by the epidermal growth factor (EGF) signaling pathway. In this study, recombinant adenoviral vectors that encode TRAIL gene from the hTERT/RGD promoter (AdTRAIL) was combined with drugs including gefitinib, elotinib, and cetuximab that inhibit EGFR and the EGF signaling pathway in non-small cell lung cancer (NSCLC) cell lines to investigate their antitumor activity. In vitro, compared to single reagent, AdTRAIL combined with EGFR inhibitors reduced proliferation and enhanced apoptosis in H460, A549, and SW1573 cell lines. Western blot results suggested that these effects were relative to up-regulation of pro-apoptosis protein BAX and down-regulation of p-AKT. In vivo, AdTRAIL combined with cetuximab resulted in a significant growth reduction in H460 xenografts without damage to the main organs of nude mice. Histological examination and TUNEL analyses of xenografts showed that cetuximab enhanced cell apoptosis induced by AdTRAIL. These results indicate that EGFR inhibitors enhanced AdTRAIL anti-tumor activity in NSCLC cell lines and that inhibiting the AKT pathway played an important role in this enhancement.
