    Abstract Xing-Nao-Jing (XNJ) is a well-known injection that has been extensively applied in clinical treatment of stroke in China. However, the underlying mechanism of clinical administration of XNJ in stroke remains unclear. In this study, a systems pharmacology strategy based on pharmacokinetic and pharmacodynamics data was applied to analyze the pharmacological effect of XNJ on stroke. Sixteen active compounds were filtered from XNJ through Drug-likeness (DL) and Brain-blood-barrier (BBB) evaluations. Ninety-four potential targets of these active components were identified by SysDT and SEA. Biological process and pathway enrichment analyses of these targets demonstrated that XNJ exerted anti-stroke effects by biological processes and pathways, such as the response to oxidative stress, regulation of blood pressure, calcium signaling pathway, and apoptosis. Integrating the compound-target network and stroke-related PPI network, we found that Akt1, HIF-1α and ITGB2 may play key roles in the treatment of stroke. The experiments demonstrated that oxycurcumenol may prevent PC12 cells from oxidative stress-induced cell damage. Our study indicates that XNJ has an effect on stroke by protecting neuro cells from oxidative stress-induced cell damage via HIF1α, and the research strategy at the systems pharmacology level is feasible to reveal the mechanisms of novel lead compounds from natural products.

    Abstract An investigation was made on the coarse woody debris (CWD) in burned forestlands in Huzhong area of Great Xing' an Mountains. The loading capacity of CWD in the burned forestlands was 24.9-181.0 m3 x hm(-2), among which, snag and log occupied 24.3%-85.9% and 14.0%-75.7%, being 6.0-93.9 m3 x hm(-2) and 15.3-138.4 m3 x hm(-2), respectively. Significant differences were observed among burned forestlands and among years. The predominant DBH class of snag and log was 2.5-20 cm and 1.5-15 m, and the height of most snags and logs was 2.5-15 m and 5-20 cm, respectively. The loading capacity of CWD had no obvious change with the recovery of forest vegetation. The characteristics of CWD had a close relationship with pre-fire forest stand conditions and burn intensity.

    Abstract The coarse woody debris (CWD) loading capacity of main forest types and of different larch forest communities in Huzhong area of Great Xing'an Mountains was investigated, with its environmental gradient analyzed by Detrended Canonical Correspondence Analysis (DCCA). The CWD loading capacity varied significantly with forest type, being the highest (0.20 m3 x hm(-2)) in spruce forest (Picea koraiensis). Different larch forest (Larix gmelinii) communities had a CWD loading capacity from 0 to 0.28 m3 x hm(-2), with the highest in Pinus pumila-Larix gmelinii (0.28 m3 x hm(-2)) and the lowest in Sphagnum magellanicum-Ledum palustre-Larix gmelinii (0), but the differences were not significant. The CWD loading capacity across the study area was complicated, which might result from the complex interplay of affecting factors. The main factors affecting the spatial pattern of the CWD loading capacity were topographic factors (elevation and slope position) and stand structure (age, canopy cover, and others), and the interaction between topographic factors and stand structure expressed the spatial gradient of CWD loading capacity in Huzhong area of Great Xing' an Mountains.

    Abstract Objective: To study the mechanism of Ma Xing Shi Gan decoction on the cytokines of Th1/Th2 in a murine model of asthma.
    Methods: The murine model of asthma was induced by OVA. Various doses of Ma Xing Shi Gan decoction were orally administered to the mice respectively. The spleen cells were cultured 3 days for measurement of IFN-gamma, IL4 and IL-5 by ELISA. After 2 days' culture, the spleen cells were treated with Trizol for extraction of total RNA. The gene expression of T-bet, GATA-3 and STAT-6 were analyzed by RT-PCR.
    Results: After the treatment with Ma Xing Shi Gan decoction, the production of IL-4 and IL-5 and the gene expression of GATA-3, STAT-6 obviously decreased.
    Conclusion: Ma Xing Shi Gan decoction may modulate Thl/Th2 balance by suppressing the gene expression of GATA-3 and STAT-6 in vivo.

    Abstract A spatially explicit landscape model LANDIS was applied to simulate the long-term effects of Dendrolimus superans Bulter disturbance on the forest landscape in Huzhong Forest Bureau of Great Xing' an Mountains. The statistical software pakage APACK was used to calculate the distribution area of D. superans and representative tree species, the aggregation index reflecting the spatial pattern, and the average area of forest patchs. The dynamics of forest landscape in the study region was simulated under two scenarios, i.e., with and without D. superans disturbance for 300 years (from 1990 to 2290). In the region, the distribution area of D. superans showed a trend of increased first and decreased then. Under D. superans disturbance scenario, the distribution area and the average patch size of Larix gmelinii in 0-150 years and the aggregation index of L. gmelinii in 0-190 years, the distribution area and the average patch size of Betula platyphylla and its aggregation index in 80-190 years, as well as the distribution area, average patch size, and aggregation index of Pinus sylvestris var. mongolica were lower or slightly lower than those under no disturbance scenario. D. superans disturbance led to the fragmentation of forest landscape to some extent.
