STC is a kind of clinically common functional gastrointestinal disease.Its pathogenesis hasn't been completely clarified,and current diagnosis and treatment norms are certainly limited.In recent years,"Brain-Gut Axis"theory has unveiled the complex bidirectional regulation mechanism between brain and intestinal tract,rendering new perspective for the research and treatment of STC.TCM theory demonstrates that there is close connection between brain and gut,has formed abundant experience in discrimination and treatment of STC and formed unique diagnosis and treatment ideas.Based on the theory of"Brain-Gut Axis"and"excess syndrome is corresponding to Zhanyu,deficiency syndrome is corresponding to Zhengsheng"in the chapter on Yangming diseases in"Treatise on Febrile Diseases",this paper elaborates on the relationship between the"Brain-Gut Axis"and STC.Meanwhile,by combining the theory of"excess syndrome is corresponding to Zhanyu,deficiency syndrome is corresponding to Zhengsheng"with the"Brain-Gut Axis"theory,it analyzes the influence of the excess and deficiency of the Yangming meridian on the mental state as well as the regulatory mechanism of the"Brain-Gut Axis",and puts forward corresponding treatment methods according to different syndromes.By integrating the relevant provisions in"Treatise on Febrile Diseases"with the"Brain-Gut Axis"theory of modern medicine,this paper makes a preliminary exploration of the laws of differentiating and treating STC,aiming to provide a theoretical basis for promoting a more comprehensive understanding of the pathogenesis of STC and developing more effective treatment strategies.

Objective: Identification of the attachment site of phage PaP3 within the genome of Pseudo-monas aeruginosa PAS. Methods:The full genome of lysogenic bacteria was cleaved by Pst Ⅰ and produce a large fragment of more than 45 000 bp, which was subsequently digested by EcoR Ⅰ. Then the fragment containing DNA sequence of phage and bacteria was cloned into pFastBacTMHT A vector, and the result of sequencing indicated the right hybrid site attR. AttL was isolated by PCR on the base of integration mechanism. And then attP and attB were indentified according to the nucleotide sequences of attR and attB. Results:A sequence of 21 bp(5'-GGTCGTAGGTTCGAATCCTAC-3') was defined to be the core site of integration, which was located at t-RNAPro gene in the genome of phage PaP3 and t-RNALys gene in the genome of Pseudomonas aeruginosa PA3. The attP and attB flanked with a set of inverted repeat and direct repeat. Conclusion:The integrated site of PaP3 within the genome of PA3 was identified and characteriged, which could be of value in investigating the mechanism of integration and gene flow between different species in the natural world.
