【摘要】 目的 探讨肥胖人群减肥后体重急剧下降导致腹壁松弛行腹壁整形手术的疗效。 方法 2003年4月-2009年10月，24例减肥后体重下降导致腹壁松弛患者中男3例，女21例，年龄28~44岁，平均36岁。其中1例合并甲状腺功能亢进，1例合并糖尿病病史；20例均通过运动、控制饮食等方式致体重下降，4例接受胃减容手术后体重下降。体重下降稳定后至腹壁整形手术时间间隔2~4年，平均2.5年；减肥前至腹壁整形手术前体重下降37~67 kg，平均下降45 kg。手术采用屈髋位，切除松弛皮肤组织，收紧腹壁及腰部松弛组织，耻骨上沿皮瓣远端去表皮后与耻骨上沿骨膜缝合固定。所有患者随访5个月~2年。 结果 23例术后2周皮瓣完全成活，切口愈合良好，无切口感染；1例术后出现耻骨上切口约2 cm表皮裂开，换药2周后切口愈合，术后腹壁平整、对称，无皮下血肿发生。随访期间切口疤痕隐蔽，阴阜无上移，腹壁平坦、对称。 结论 该腹壁整形手术方式效果良好，术后并发症少，值得推广。From April 2003 to October 2009, 24 obese patients, including three males and 21 females, developed abdominal chalastodermia caused by weight loss. Their age ranged from 28 to 44 years old with an average age of 36 years. Among them, one had hyperthyroidism and one had a medical history of diabetes. Twenty patients lost weight by exercise and diet, while the other four lost weight through stomach reduction surgery. Time span from weight loss to abdominal plastic surgery was two to four years, averaging at 2.5 years. During the time from before weight loss until the surgery, weight loss ranged from 37-67 kg, averaging at 45 kg. The surgery adopted the position of bending hip. The loose skin was removed; abdominal wall and loose waist tissues were tightened; and the far end of flap without skin along the upper edge of pubis was sutured with the periosteum. All patients were followed up for a time ranged from five months to two years. Results Flaps survived within two weeks after the surgery, incision healed perfectly, and no infection occurred to the incision for all the patients except in one case, there was a 2 cm of skin fissure in the upper incision which was cured after two weeks of dressing. After the surgery, the abdominal wall was flat and symmetrical without subcutaneous hematoma. During the follow-up, scars were well hidden, mons pubis was not shifted upward, and the abdominal wall was flat and symmetrical. Conclusion The abdominal wall plastic surgery has a good clinical outcome with few complications, which is worth being popularized.

【摘要】 目的 探讨中成药参附注射液对大鼠深Ⅱ度烧伤创面愈合的影响。 方法 选用16只Sprague-Dawley（SD）大鼠，随机分为实验组、对照组，每组各8只，建立20%体表面积深Ⅱ度烫伤模型。烫伤后即刻及此后每天，实验组大鼠以参附注射液20 mL/kg腹腔注射给药，1次/d，连续给药5 d；对照组给予注射等剂量的生理盐水。分别于致伤后的7、14 d取创面组织块，光学显微镜观察成纤维细胞及胶原纤维生长情况，电子显微镜观察致伤后14 d成纤维细胞细胞器情况，分别计算烧伤后第7、14天两组的创面愈合率，并观察比较两组创面愈合的时间。 结果 所有选入实验的SD大鼠均存活至实验结束。实验组、对照组术后第7天创面愈合率分别为（36.34±2.55）%及（33.13±2.62）%，两组差异有统计学意义（t=2.486，P=0.027）；实验组、对照组术后第14天创面愈合率分别为（75.71±2.29）%及（72.36±2.85）%，两组差异有统计学意义（t=2.590，P=0.022）；实验组、对照组创面愈合时间分别为（20.88±1.36）、（22.94±2.16） d，两组差异有统计学意义（t=-2.286，P=0.0395）。伤后7、14 d创面组织块切片光学显微镜观察发现，实验组肉芽组织及胶原纤维较多，排列更有序，表皮基底细胞增殖活跃，炎症反应较轻；伤后14 d时电子显微镜观察发现，实验组成纤维细胞的细胞器更丰富，分泌胶原更多，实验组创面愈合情况优于对照组。 结论 腹腔注射参附注射液可以促进烧伤创面的愈合，其可能的机制为清除氧自由基，抗脂质过氧化。【Abstract】 Objective To explore the effect of Shenfu injection on promoting healing of deep partial-thickness burn wound in rats. Methods Sixteen Sprague-Dawley (SD) rats were randomly selected, and deep partial-thickness burn with 20% of the body surface was inflicted. The rats were randomly divided into experimental group and control group with eight in each group. Rats in the experimental group were treated with abdominal injection of Shenfu injection at a dose of 20 mL/(kg•d) for five days continually, and rats in the control group were treated with the same dose of 0.9% saline solution. The growth of granulation tissue and collagen fibers were evaluated under light microscope at the seventh and the fourteenth day. The growth of fibroblast was observed under transmission electron microscope at the fourteenth day. The cure rate of both groups of rats at the seventh and fourteenth day was calculated. Then we compared their healing time and the cure rate of the traumatic wound respectively. Results All rats had survived until wound healing. The cure rate at the seventh day for the experimental group and the control group was (36.34±2.55)% and (33.13±2.62)%, and their difference was statistical (t=2.486, P=0.027); At the fourteenth day, the cure rate was respectively (75.71±2.29)% and (72.36±2.85)% with a significant difference between each other (t=2.590, P=0.022). The healing time of the experimental group (20.88±1.36) was significantly shorter than that of the control group (22.9±2.16) (t=-2.286, P=0.040). At the seventh and fourteenth day, light microscope observation showed that the growth of granulation tissue and collagen fibers for rats in the experimental group were much more than that in the control group, the basale cell proliferation was more active, and inflammation was slighter. Through transmission electron microscope, we observed more fibroblast and collagen in the experimental group, which showed a better cure than the control group. Conclusion Shenfu injection can significantly promote wound healing of deep partial-thickness burn. It may possibly get this effect through anti-oxidation.
Objective To investigate and compare the effectiveness of perichondrial cutaneous graft (PCCG) of dorsal auricle for repairing defect after excision of melanocytic nevus in different parts of the face. Methods Between February 2008 and October 2012, 29 cases of facial melanocytic nevus were admitted. There were 11 males and 18 females, aged 3-25 years (median, 11 years). The locations were the upper eyelid in 5 cases, the nose in 15 cases, and the buccal region in 9 cases. The size of the nevi ranged from 1.2 cm × 1.0 cm to 4.0 cm × 2.2 cm. Defects after excision of nevi were repaired by PCCG of the dorsal auricle, which size ranged from 1.5 cm × 1.5 cm to 4.2 cm × 2.5 cm. The postoperative effectiveness was scored by patients according to color match, scar formation, and flatness of the reception site. The satisfaction evaluations were compared by the score among different parts. Results All the PCCG survived. All the patients were followed up 7-15 months (mean, 10 months). All the reception site had good color match and acceptable scar formation. The nasal part had good flatness, and the upper eyelid had poor flatness. Score comparison showed no significant difference in color match between 3 parts (P gt; 0.05). Nasal part had significantly less scar formation than buccal region and upper eyelid (P lt; 0.05), but no significant difference between buccal region and upper eyelid (P gt; 0.05). Nasal part and buccal region both had significantly better flatness than upper eyelid (P lt; 0.05), but no significant difference between nasal part and buccal region (P gt; 0.05). The overall evaluation score of nasal part and buccal region was significantly higher than that of the upper eyelid group (P lt; 0.05), and the score of the nasal part was significantly higher than that of the buccal region (P lt; 0.05). Conclusion PCCG of dorsal auricle has a good color match in repair of facial defect, especially in repair of nasal defect with good flatness and no obvious scar formation.
