This paper introduced the concept of accumulation-dispersing method and its theoretical basis as well as clinical application in the treatment of gland diseases. With three diseases, which were the Sjogren’s syndrome, cystic hyperplasia of breast and benign prostatic hyperplasia, as clues, common characteristics from etiology, pathology and pathogenesis were elaborated from the anatomical features, pathological characteristics and meridian pathways for the gland diseases. The disease pathogenesis always belonged to“mass” and“knot” of traditional Chinese medicine (TCM). The detailed clinical applications were as follows. For the pattern of blood stasis, the treatment principle was to promote blood circulation and to resolve masses. For the pattern of phlegm, the treatment principle was to reduce phlegm and to resolve masses. For the pattern of heat, the treatment principle was to clear heat, to relieve toxin and to resolve masses. For patients of“tumor” or“phthisis”, the treatment principle was to strengthen vitalqi and to eliminate stagnation. Worm medicine should also be combined during accumulation-dispersing. This paper provided referential ideas and methods for TCM treatment of gland diseases.

Objective To summarize the experience in treating coronary artery fistula (CAF) by using Guglielmi detachable coils. Methods During the period from July 2009 to November 2014 at the Affiliated Changhai Hospital of Second Military Medical University, interventional treatment of CAF by using Guglielmi detachable coils was performed in 40 patients. The clinical data were retrospectively analyzed. The feasibility, safety and effectiveness of this technique were evaluated. Results Successful transcatheter closure of CAF with Guglielmi detachable coils was achieved in all 40 patients; the average Guglielmi detachable coils used in each patient was(2.33±1.38) coils. No procedure-related complications occurred. Intra-operative angiography showed that residual shunt completely disappeared in 12 patients (30%) and blood flow was significantly decreased in 28 patients (70%). All the patients were followed up for 1-65 months, neither complications such as recurrent bleeding and ischemia nor stenosis and occlusion of related arteries, or fistula cavity rupture occurred. Conclusion The use of Guglielmi detachable coil in interventional treatment of CAF is safe and effective, although its long-term effect needs to be further verified.

Objective To explore the molecular mechanisms of primary amenorrhea by using arrayCGH technology. Methods Ten patients with primary amenorrhea and 10 female volunteers with regular menstrual cycles as healthy controls were selected. All patients and control samples were analyzed by conventional chromosome analysis (G-banding technology) and array-CGH technology, respectively. ArrayCGH was performed using Affymetrix Cytogenetic 2. 7M arrays following the manufacturer's standard protocol. Results Both the patient group and control group analyzed by conventional G-banding karyotype technology showed a negative result with a normal female karyotype: 46, XX. The result of array-CGH analysis demonstrated a microdeletion of approximately 110 000 bp located at the end of the short arm of X chromosome [46, X, del (X) (p22. 33 )] were identified in 5 patients, which was not detected in the control group. All healthy control samples by array-CGH analysis showed no pathological DNA copy number variation. Conclusions Array-CGH technology can improve the diagnosis rate of chromosomal disease at the DNA level. It is necessary to provide array-CGH for higher resolution genetic analysis of idiopathic primary amenorrhea patient who can not be identified by conventional technology.
