[Effects of water and nitrogen coupling under furrow irrigation on tree growth, absorption and utilization of water and nitrogen of ].

We explored the coupling effects of water and nitrogen in furrow irrigation on the growth and absorption and utilization of water and nitrogen in young poplar trees (triploid ), under three irrigation levels (W, W, W; when the soil water potential of 40 cm under the ditch reaches -20, -33 and -45 kPa respectively, irrigate), four N application levels (N, N, N and N; the fertilization amount was 120, 190, 260 and 0 kg·hm·a), and natural conditions (CK). Based on the growth status of trees, the optimal combination of irrigation level and nitrogen application rate under furrow irrigation conditions was determined. The results showed that WN (high water and low fertilizer; soil water potential threshold for initiating irrigation was -20 kPa and N application rate was 120 kg·hm·a) had the strongest effect on the stand productivity, with a value of 33.

Efficacy and survival-associated factors with gefitinib combined with cisplatin and gemcitabine for advanced non- small cell lung cancer.

Objective: To analyze the efficacy and survival associated factors of gefitinib combined with cisplatin and gemcitabine for advanced non-small cell lung cancer.

Materials And Methods: A total of 57 patients with advanced non-small cell lung cancer (NSCLC), who received platinum-based chemotherapy regimens for more than 1 cycle, were treated with gefitinib combined with cisplatin and gemcitabine until disease progression. Efficacy, survival time and adverse reactions were observed.

[Progress of taxonomic study on Fritillaria (Liliaceae) medicinal plant].

In this review, we described the taxonomic study of the Fritillaria medicinal plant in the recent years. The taxonomic study of the Fritillaria medicinal plant was carried out from three main aspects: the traditional morphological character, the characteristic constituents of the plant and genotyping and species identification of Fritillaria by DNA chips. By comparison, we concluded that the DNA chip technology can provide a rapid, high throughput for genotyping and quality assurance of the plant species verification.

[Identification of Chinese medicine material of Fritillaria by themogravimetric/diffrential thermal analysis].

Objective: To provide a quick and simple method to identify different Chinese medicine material of Fritillaria.

Method: The thermograms and differential thermograms of nine Fritillaria powders were obtained by thermal analyzer.

Result: By analyzing the thermograms of nine Fritillaria powders, we concluded that the thermal stability of nine Fritillaria powders was much different each other due to the different geography origin.
