OBJECTIVE：To predict the pot ential target and mechanism of Xintong Changluo Method carrier-Compund Shensu Ⅱ couplet medicine of Bupleurum falcatum-Scutellaria baicalensis intervening in podocyte lesion ，and to provide reference for the development of sequential clinical and basic research of Xintong Changluo Method in the prevention and treatment of podocyte lesion. METHODS ：Based on TCMSP database ，chemical components and target protein of B. falcatum and S. baicalensis were retrieved，and Cytoscape 3.2.1 software was used to draw a “TCM-component-target”network. The targets related to podocyte lesion were searched from OMIM database ，DrugBank database and Digsee online text ，and the intersection genes of above targets and“B. falcatum -S. baicalensis ”target were obtained by Venny 2.1.0 online mapping tool. The protein-protein interaction （PPI） network was constructed by STRING database ，and the core targets were obtained by topology analysis of the network by using CytoNCA plug-in Cytospace 3.2.1 software. With the help of DAVID database ，the fu nction of Gene Ontology （GO）was annotated and KEGG pathway was enriched ；and the enrichment results were visualized through OmicShare Tools online mapping platform. RESULTS ：Based on retrieval results of TCMSP database，44 active components were obtained ，involving 13 com of B. falcatum and 32 of S. baicalensis ； stigmasterol is common component of B. falcatum and S. baicalensis Quercetin，kaempferol and wogonin were the compounds withmain potential targets. T he target proteins wi th high node degree were prostaglandin endoperoxide synthase 2（PTGS2），PTGS1， nuclear receptor coactivator 2 and heat shock protein 90α，which were associated with 37，30，25 and 25 active components respectively. Twenty genes were obtained from the interaction between “B. falcatum -S. baicalensis ”and podocyte lesion related targets，including PTGS2，VEGFA，MMP9，TNF and IL6. PPI network diagram of the above intersection genes contained 20 nodes and 110 lines，with MMP9，VEGFA，IL6 and other genes at the core. The results of GO analysis showed that a total of 154 biological information items were obtained （P＜0.05），including 139 biological process items ，8 cell composition items and 7 molecular function items. Among them ，biological processes mainly involved in the positive regulation of NO biosynthesis process ， inflammatory response ，immune response. Cell composition mainly involved in extracellular space ，extracellular region ，external side of plasma membrane ，etc.，and molecular function mainly involved in protein binding ，cytokine activity ，growth factor activity，etc. At the same time ，47 KEGG pathways were obtained （P＜0.05），mainly including cytokine-cytokine receptor interaction，rheumatoid arthritis ，malaria，cancer signaling pathways. CONCLUSIONS ：The active components of Compund Shensu Ⅱ couplet medicine of “B. falcatum -S. baicalensis ”may act on MMP9，VEGFA，IL6，TNF and other targets through cytokine-cytokine receptor interaction ，rheumatoid arthritis ，malaria，cancer signal pathway ，so as to play its intervention effect on podocyte lesion.

Sha （痧） is an acute infectious disease characterised by the appearance of rashes on the skin， caused by exposure to epidemic toxin and pestilent qi. Sha Zhang Yu Heng （《痧胀玉衡》） discussed the treatment principles and methods， and listed collateral bloodletting as one of the main treatments. Through organizing the articles and proved cases， we found that the author believes Sha （痧） is caused by epidemic pathogen， belonging to heat toxin with rapid changes， so timely treatment for qi and blood simultaneously could achieve the effect of transforming qi into defensive qi. Sha Zhang Yu Heng focuses on patient's position during treatmet， the material of the needle， the site of treatment， the quantum of stimulation and the operation of the contraindications and other essentials. According to the depth of the disease location， use traditional Chinese herbal medicine， scraping together to identify the root of the disease. In addition， diet suggestions for the prevention of the recrudescence of disease are also described in detail.
