A study on the treatment of chloasma with moxibustion based on the theory of“Yang transforming Qi,and Yin shaping”

Background:“Yang Transforming Qi and Yin shaping”comes from“Plain Question Yin and Yang should be like the theory”.Chinese medicine believes that the imbalance of yin and yang is the cause of human diseases.One of the strengths of TCM in treating diseases is holistic regulation.The theory of“Yang transforming Qi,and Yin shaping”implies a strong holistic view.Chloasma,one of the common skin diseases,seriously affects the physical and mental health of patients due to its unclear etiology,difficult treatment and easy recurrence.The occurrence and development of chloasma are closely related to internal organs.This paper is based on the theory of internal meridian,“Yang transforming Qi,and Yin shaping”which attaches importance to the concept of“Yang Qi”,from a new understanding of the pathogenesis etiology of chloasma.Methods:The author believes that the incidence of the disease is the deficiency of Yang Qi,which can’t promote the movement of Qi and blood to nourish the face,resulting in tangible material condensation,so proposes that this disease needs to be promoted by Yang transforming Qi and warm to dissipate.Moxibustion belongs to the fire,and its warming effect can dissipate the tangible evil.Results:Combined with clinical practice and the theory of internal meridian,the author elaborated that moxibustion is one of the effective methods for treating chloasma,which provides a new way of thinking for the treatment of chloasma.Conclusion:“Yang Transforming Qi and Yin shaping”can be used to guide the treatment of chloasma.

The four stages of development： a historical prospective of external counterpulsation

There are four stages in medical device development.The beginning starts with some new understanding of physiological concepts which evolve into the formation of an innovative idea. The second stage is the technical development phase,from idea to the development of a design to technical reality. At this stage,capital funding and patent applications for the development are necessary but they are not considered here. The third stage is experimental and clinical studies,a data gathering phase to provide evidence of safety and effectiveness of the applications of the device.

INITIAL EXOERIENCE OF PACING LEAD EXTRACTION USING MECHANICAL AND LASER-ASSISTED DEVICE

Objective:To describe our experience on lead extraction in Hong Kong.Background:Pacing lead extraction is required when there is infection,lead fracture with protrudingfiagments and absence of venous access during lead replacement.Methods:We performedthe first lead extraction in Hong Kong using the Cook sheath on March 1995.Since 1996,Spectranetics laser sheath using Excimer Laser System(Model CVX-300)was used.Theprocedure was performed under general anesthesis(Cook sheath)or conscious sedation(Laserextraction).Results:Twenty patients with a total of 26 leads were extracted.The indicationsfor lead extraction were:I.Fracture retention wire of Aceufix lead(15 patients)2,Infectedpacing leads(4 patients).3.Venous access problem(1 patient).9 leads were extracted withthe Cook sheath,the remaining 17 leads by larer-assisted device.There were 20 atrial leadsand 6 ventricular leads from Telectrontics,Medtronic.Cordis and Intermedics,with thelongest irnplanted lead of 15 years.Snccessful extraction eas achieved in 24/26(93%)of leadsIn one patient,fracture of outer insulation of Accutix at the superior vena cava occurred afierusccessful removal of the lead from the atrium,and this requited venotomy for extraction.Failure of advancement of locking styler occurred in another patient with an uninfectedvetricular lead which was not extractde,There was no mortality nor any other majorcomplictaion,Re-implantation was performed at the same setting except for the 4 infectedcases Conelmslom:Lead extraction can be perfomned effectively and smfely with,either theCook or Lmser extraction method,the latter can be chieved without general anesthesia.Aslead extraction may be incteasingly used in the young patients to reduce the qumber ofhardwares inside the beart and for the purpose of schieving venous access,lends that areabandoned at the time of pacernaker change should be capped rather than cut to facilitate leadextraction in the futureA.
