Sweat pore serves as the central regulator for ascending， descending， exiting and entering of qi movement， the circulation of essence， blood， and body fluids， and the nourishment of zang-fu organs. Its proper function depends on maintaining smooth flow and avoiding stagnation. Cough variant asthma （CVA）， in traditional Chinese medicine， falls under the "wind cough" category. The dysfunction of sweat pores' opening， closing， ascending， and descending is integral to the pathogenesis of CVA. This article focused on the dynamic changes in sweat pores' dysfunction throughout the progression of CVA， categorized into three stages，i.e. loss of pivot function， blockage of sweat pores， and lack of nourishment. The treatment approach centers on "wind medicinal opening sweat pores"， so for the initial stage， the focus is on activating sweat pores and dispelling wind， diffusing the lungs and rectifying qi； for the progression stage， the strategy shifts to unblocking sweat pores and dispersing wind， clearing lung stagnation and resolving obstructions； for the resolution stage， the emphasis is on nourishing sweat pores and defending against wind， strengthening the lungs and consolidating the body's foundation. This approach provides a systematic approach to the clinical diagnosis and treatment of CVA.

Objective To observe on therapeutic effect of moxibustion combined with traditional Chinese medicine "Sihuang" powder for the treatment of PICC after mechanical Phlebitis. Methods The total 63 cases of PICC postoperative mechanical phlebitis were randomly divided into experimental group ( n=33 ) and control group ( n =30 ) , and the patients of experimental group was treated by external application of moxibustion combined with traditional Chinese medicine of"Si huang" powder, the control group received 50%magnesium sulfate wet compress, to observe the curative effect of two sets of mechanical phlebitis. Results A total of 29 cases were cured, 2 cases with effect, 1 cases improved and 1 case invalid in the experimental group;20 cases were cured, 4 cases with effect, 4 cases improved and 2 cases was invalid in the control group. There was a statistically significant difference between the two groups (Z =2. 007,P <0. 05). Conclusions The curative effect is significant about Moxibustion combined with Chinese medicine external application of "Si huang" powder for patients with mechanic phlebitis caused by PICC.
