The clinical classification method research of keloid / 中华整形外科杂志

<p><b>OBJECTIVE</b>To explore the clinical classification method of keloids and providing a thread for the treatment of keloids.</p><p><b>METHODS</b>To summarize the 600 cases of keloid patients we accepted and diagnosed from November 2004 to October 2012, and filling in keloid patients information sheet, recording the keloids form by photographs, analyzing the treatment, putting forward the classification method of keloids in clinic.</p><p><b>RESULTS</b>According to the position and quantity that keloids grow, the keloid patients are divided into four major categories:one in single site, one in each site, more than one in single site and more than one in each site; According to the area and thickness of keloids, the keloid single lesion is divided into four subclasses: type of small area and thin, type of small area and thick, type of large areas and thin,type of large areas and thick; According to the number of lesions, keloid multiple lesions is divided into two subgenera: isolated multiple and dispersion multiple, different kinds of keloids suit different methods of treatment.</p><p><b>CONCLUSION</b>The clinical classification method of keloids can be used to provide thought for the treatment of keloids, and have a good application value.</p>

Comparison of biological behavior between triple-negative breast cancer and non-triple- negative breast cancer / 南方医科大学学报

<p><b>OBJECTIVE</b>To summarize the epidemiological and biological features of triple-negative breast cancer (TNBC) and non-triple-negative breast cancer (non-TNBC) to provide reference for devising individualized therapy and making prognostic evaluation.</p><p><b>METHODS</b>The 5-year follow-up data were collected from 231 patients with pathologically established diagnosis of breast cancer treated in the Affiliated Hospital of Ningxia Medical University and Yinchuan People's Hospital between Jan. 2002 and Dec. 2004. The epidemiological and clinicopathological characteristics as well as the recurrence, metastasis and 5-year survival were compared between TNBC group and non-TNBC group.</p><p><b>RESULTS</b>TNBC accounted 17.3% of the total breast cancer cases enrolled in this study. The tumor size and rates of recurrence and metastasis (especially visceral metastasis) were significantly greater in TNBC group than in non-TNBC group (P<0.05). The TNBC patients showed significantly lower 3- and 5-year survival rates than the non-TNBC patients (P<0.05), and TNBC patients with positive lymph nodes in clinical stage II had also a lower 5-year survival (P<0.05). Cox regression model analysis identified the patients' age, primary tumor size, clinical stages and triple-negativity as the independent risk factors for breast cancer.</p><p><b>CONCLUSION</b>Compared to non-TNBC patients, patients with TNBC have higher rates of local recurrence and invasion, visceral metastasis and poorer prognosis, and a lower rate of 5-year survival. The triple negativity represents an independent factor for prognosis evaluation of breast cancer.</p>

Rhinoplasty in Chinese: management of lower dorsum and bulbous nasal tip / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Bulbous nasal tips and lower dorsa are common facial features in Chinese people, and surgery to reshape these is frequently requested. The use of silicone implants in rhinoplasty has been widely used in China for many years, but is not suitable for patients seeking Caucasian tip shapes. The creation of an excessively high tip supported only by a silicone implant inevitably leads to implant extrusion. Although many rhinoplasty techniques have been used in Caucasian patients, there is currently no suitable method for Chinese patients, whose anatomy differs from that of Caucasians. The present study was aimed to investigate the clinical outcome of a novel method of rhinoplasty in Chinese people.</p><p><b>METHODS</b>Eighty patients underwent rhinoplasty using our method between 2002 and 2006. We classified the patients into three types, according to the distance between tip defining points, and used different techniques accordingly. Furthermore, an innovative cartilage carving method and a tip fibro-fatty tissue flap were designed and combined with traditional techniques, such as insertion of silicone implant, cartilage grafts, suture techniques and cephalic trimming to reshape the nasal contours. The followup period was 10 - 60 months (average, 21 months).</p><p><b>RESULTS</b>Remarkable modifications in nasal contours were achieved. No complications developed in any of the 80 patients. Seventy-eight patients were satisfied with the results. The outcomes remained unchanged over time.</p><p><b>CONCLUSION</b>Our method is effective and suitable for the treatment of Chinese patients with lower dorsa and bulbous nasal tips.</p>

Latissimus dorsi transfer to restore thoracic malformation of Poland's syndrome / 中华外科杂志

<p><b>OBJECTIVE</b>To study the methods and points for attention of latissimus dorsi muscle flap transplantation to correct the thoracic malformation of Poland's syndrome.</p><p><b>METHODS</b>From 1995 to 2003, 10 patients were diagnosed of Poland's syndrome with absence of pectoris major muscle in all patients. The latissimus dorsi muscle flap was exposed and transferred through a vertical lateral thoracic cut and a short cut beneath the axillary fold. Reconstruction of the anterior axillary wall is one of the major goals to be achieved in this operation.</p><p><b>RESULTS</b>All of the latissimus dorsi muscle flaps survived. Satisfactory outcomes were achieved after 1-2 years of follow-up.</p><p><b>CONCLUSION</b>The latissimus dorsi muscle flap has a stable and reliable blood supply. It is an ideal muscle flap to restore the thoracic malformation of Poland's syndrome.</p>
