Objective To summarize the recent development in the plastic and reconstructive surgery. Methods The related literaturewas reviewed and the main achievements in the field of plastic surgery were summarized. Results Plastic and reconstructive surgery was one ofthe quickly-developed fields in the world medicine, especially aesthetic plastic surgery. Reconstructive plastic surgery and aesthetic plastic surgery would be bined in the future. The “aesthetic hand surgery” was a very important branch of the hand surgery,so not only the function recovery of the hand deformities but also the aesthetic sculpture for the deformed hand should be emphasized. Evaluation on measurement of the facial paralysis reconstruction was a main part of the facial examination. The allotransplantation of the face became more developed. The anatomical research on the cutaneous perforator arteries, vascularisation of the biceps femorismuscle, and the gracilis perforator flap was well performedby the plastic surgeons.
目的:比较不同麻醉方法在腹腔镜妇科不孕检查及治疗术中的效果和安全性。方法:选择不孕拟在腹腔镜下行检查及治疗术的患者60例,随机分为三组,每组20人,分别进行连续硬膜外麻醉(简称EA组);静吸复合全身麻醉(简称GA组);连续硬膜外麻醉加静吸复合全身麻醉(简称EGA组),观察比较三种麻醉方法对患者呼吸,循环及麻醉效果的影响。结果:三种麻醉方法均可保证手术完成,EA组术中管理较为麻烦,GA组循环波动大,EGA组麻醉效果更好,各种药物用量减少,患者血液动力学更稳定,恢复快,管理更轻松。结论:连续硬膜外麻醉加静吸复合全身麻醉(EGA)可避免其它两种麻醉方式不足,各取长处,更适用于腹腔镜妇科不孕检查及治疗术麻醉。
Objective To assess clinical outcomes of valve-sparing aortic root replacement for patients with aortic root aneurysm.?Methods?From February 2001 to September 2010， sixty patients with aortic root aneurysm underwent valve-sparing aortic root replacement in Fu Wai Hospital. There were 44 male patients and 16 female patients with an average age of 37.2±13.0 years （ranging from 9-64 years）. Fifteen patients had aortic dissection， 10 patients had ascendingaorta aneurysm， 25 patients had Marfan syndrome， and 2 patients had bicuspid aortic valve. Aortic root reconstruction was performed in 53 patients and aortic valve reimplantation was performed in 7 patients. Preoperative and postoperative heart function and degree of aortic insufficiency （AI） were compared.?Results?Valve-sparing aortic root replacement was performed in all patients. There was no in-hospital death or severe postoperative complications in this group. The median duration of mechanical ventilation was 13 hours （ranging from 2 to 1 110 hours） ， while the mean intensive care unit stay was 2.7±2.5 days （ranging from 1 to 18 days） . Postoperative echocardiography showed AI degree was significantly reduced in all the patients. Only three patients had moderate to severe AI， and all the other patients had none or trivial AI. All the patients were followed up for 2-122 （61.5±35.9） months. During follow-up， 4 patients were lost， 9 patients died， and the overall survival rate was 83.9% （47/56）. Two patients underwent aortic valve replacement in the 13 th and 14 th postoperative month respectively because of severe AI. Heart function of 47 patients was significantly improved compared with their preoperative heart function. Thirty-five patients （74.4%）were in New York Heart Association （NYHA） functional classⅠ， and 8 patients （17.0%） were in class II. Forty patients （85.1%）were free from moderate or severe AI.?Conclusion Valve-sparing aortic root replacement has satisfactory long-term outcomes for patients with aortic root aneurysm， and valve-related complication rate is low.
OBJECTIVE: To investigate the expression and distribution of platelet derived growth factor receptor-beta(PDGFR-beta) in normal skin and keloid and to discuss its biological function in keloid formation. METHODS: 1. To detect the expression and distribution of PDGFR-beta in normal skin and keloid tissue by immunohistochemistry; 2. To detect the receptor expression in vitro by Flow cytometry (FCM); 3. To detect the subcellular distribution of receptor by Laser confocal microscope. RESULTS: 1. Immunohistochemistry showed that normal skin and keloid tissue were almost the same in expression but different in distribution of PDGFR-beta; 2. There was more expression of PDGFR-beta in normal fibroblasts than that in keloid fibroblasts in vitro by FCM; 3. Laser confocal microscope revealed that the PDGFR-beta concentrated on the surface of cell membrane in keloid fibroblasts, but in normal skin fibroblasts, the receptors were coagulated on the nuclear membrane and intranucleus. CONCLUSION: Compared with the fibroblasts in vivo, there was a difference of the PDGFR-beta expression in fibroblasts in vitro, more expression of PDGFR-beta in normal fibroblast than that in keloid fibroblast in vitro; and the subcellular distribution of PDGFR-beta was different in normal skin and keloid fibroblasts. The characteristics of the expression and distribution of PDGFR-beta in keloid may contribute to the formation of keloid.
