Methods Forty rats were randomized into normal control group and FS group. The normal control group was fed with conventional forage. FS group was fed with dry forage mixed with FS powder for 3 months, the preliminary dose of FS was 200 mgkg^(-1)d^(-1) and then increased progressively by l00 mgkg^(-1)d^(-1) to ensure over half of the rats having diarrhea, and the final dose was 2800 mgkg^(-1)d^(-1). The frequency and amplitude of colic slow wave were detected and the changes of myenteric plexus and ICC were observed by zinc iodide -osmic acid staining method.

Using whole-cell patch clamp recording, we observed multiple distinct ATPinduced currents in isolated DRG neurons of adult rats, each with unique desensitizing kinetics.β,γ-meATP, agonist of P2X1 receptor also induced fast inactivating and slowly desensitization current in small DRG neurons. PDBu, a selective agonist for PKC, decreased the P2X receptor-mediated inward currents in a dose-dependent manner, while SNP, nitric oxide donor, potentiated the ATP-evoked current through NO-cGMP pathway.

In other words, underground water is an essential water resource, accounting for 41%-83% of the total. Meanwhile, the formation of limestone soil is slower.(2) Guangxi is a typical karst region. A large difference is noticed in vegetation coverage between karst regions and non-karst regions. The average coverage of bush and forest communities is 14.81% and 12.13% in the karst regions, 1.92% and 31.3% in the non-karst regions.(3) The wide distribution of rocky desertification in Guizhou Province indicates the karst environment is strongly affected by carbonate rocks'properties.

The proposed robust road main direction detection method consists of initial main direction extraction based on the direction histogram of structure tensor and precise direction detection on vectorized edge image. Experiment results demonstrate its robustness and precise. The proposed Gibbs-sampling-based method models road network with marked point process and can effectively extract road network with initial configuration. However it is slow and still can not deal with single and isolated road segment. These problems can be solved by the real-time method. And experiments verify that the real-time method is fast during extracting road segment.
