Objective To investigate the combination of blepharoplasty with rhytidectomy for correction of the aging face. Methods In addition to conventional rhytidectomy, the operation included transection of lower orbicularis palpebrorum ligament ,excision of the herniated orbital fat, suspension of lower obicularis palpebuorum muscle. Results The method has produced a satisfied result in 25 cases since 1999. Conclusion On the base of conventional rhytidectomy, we transect the lower orbicularis palpebrorum ligament to elevate and stabilize the orbicularis muscle to the periosteum above the level of lateral canthus, which improves nasopalpebromalar groove and obtains more youthful appearance of the mid face.

Objective To investigate the possibility of using the results of breast ultrasound and Cohen-classification to determine the gynecomastia patients' subtype, and to evaluate the effectiveness of different surgical methods based on the classification. Methods In the past 3 years, 40 patients with gy-necomastia were treated in this hospital. The patients" age ranged from 18 to 50 years, with an average of 21.38. All the patients had the bilateral lesions, and their pathological diagnosis was gynecomastia. The mammary gland resected from each side weighted from 30 to 180 grams. The total fat volume liposucted ranged from 200 ml to 1 200 ml. As a routine, we performed breast ultrasound examination before the op-eration on each patient. According to the different echo, we marked the extent of breast gland on the chest walls and determine the Cohen classification of the patients. For breast tissue hyperplasia, we only resected the gland under the direction of the chest wall marks. For fat tissue hyperplasia, we just per-formed liposuction. For patients with mixed fat and gland hyperplasia, we combined these two methods rationally. If necessary, the procedures was repeated. Results With the help of breast ultrasound exami-nation, the operating procedure was more accurate and simple, as a result, our treatments had less injury and no severe complications. After a following-up of 6-36 months, satisfactory results were achieved, with normal male chest appearance and small obscure scar. Conclusions Male breast surgery is totally different from the females. The Cohen classification has been determined for each gynecomastia patient, based on the results of breast ultrasound examination, which helps choose the surgical methods and procedures and decrease surgical injuries and complications, with satisfactory results.

Objective To evaluate the method for vaginal treconstruction with muscle sparing verti-cle rectus abdominis myocutaneous flap(MS-VRAM flap). Methods From September 2006 to April 2008, MS-VRAM flaps were used for vaginal reconstruction in 9 patients (20 to 35 years old), ancl all ca-ses were congenital absence of vagina. Before operation, the inferior epigastrie arteries were detected by the Doppler and the flaps based on the perforators ranged from 6 cm×20 cm. MS-VRAM flaps were ele-vated and then transferred to reconstruct the vagina. Results All 9 cases of MS-VRAM flaps survived completely. No complications occurred at donor site of abdominal wall. With 2-12 months' follow-up, the patients were satisfied with the results. Conclusion Despite technical difficulties in elevating the MS-VRAM flap, the flap is a good choice for vaginal reconstruction.

Objective Thermal burns of the anterior chest disfigure the female breast, and the postburn breast deformity is a sequela of severe scar contraction of the burned chest. For deformities that affected the mammary development, museulocutaneous flaps were used. Here we introduce our experience in using the latissimus dorsi myocutaneous island flap in burned breast reconstruction. Methods During the past 7 years, 7 female patients with such deformities required reconstruction, the expanded or unex-panded latissimus dorsi musculocutaneous island flaps were used in the partial reconstruction of burned breast. In the mild deformities group (2 cases), unexpanded latissimus dorsi musculocutaneous island flaps were used. For patients with undeveloped mammary glands (5 cases), expanded latissimus dorsi musculocutaneous island flaps were used. Results The procedure was performed in 7 patients and all the flaps were alive, with significant improvement of breast appearance. The complication rate was low. There were no deformity and dysfuction in the donor site. Conclusions The technique has many advanta-ges: beautiful contour of breast, good blood supply of the flap, no donor site morbidity. It provides the plastic surgeon with an excellent, safe and consistently successful method for burned breast reconstrue-tion. This experience has led to development of surgical principles and techniques tailored to this particu-larly difficult problem.

Objective To investigate the mechanism of liposome PGE1 on the survival of the expanded flap.Methods The minipigs were set up as an animal model.They were divided into 2 groups.The expanded flaps (8 cm ×2 cm) were designed and elevated on the back of an minipig.An image analysis technology was used to evaluate the survival rate of the expanded flap,while realtimePCR technique was used to investigate the molecular mechanism.Results The survival area of the expanded flap in the Lipo PGE1 group was significantly enlarged (P＜0.01) compared with the control group.The VEGF,iNOS and Ang-1 gene expression decreased,but TGF-β1 gene expression increased.But there was no significant difference between two groups (P＞0.05).Conclusions The Lipo PGE1 could promote survival rate of the expanded flap,but the mechanism does not involve the regulation of VEGF,iNOS,Ang-1 and TGF-β1 gene expression.

Objective To investigate the classification and surgical management of patients with palpebral bags. Methods A total of 200 cases with palpebral bags who underwent surgical treatment between May 2003 to August 2008 were retrospectively analyzed. The palpebral bags were classified according to skin flaccidness, bulging of excessive orbital septum fat and tarsus relaxation. The postoperative cosmetic results were also assessed. Results Of the 200 treated cases, the postoperative cosmetic results were assessed as very satisfactory in 178 (89 % ) cases, as satisfactory in 18 (9 % ) cases, and as dissatisfactory in4 (2 % ) cases. Conclusion Patients with palpebral bags should be treated with different surgical methods according to their different types.

Objective To ummarized the clinical characteristics of lactic acidosis combined with hypoglycemic coma,diabetic ketoacidosis and hyperkalemia,so to improve the physician's treatment ability by summary the clinical feature of lactic acidosis combined with hypoglycemic coma,diabetic ketosis and hyperkalemia.Methods Analyzed the clinical characteristics and disease development of one case with lactic acidosis combined with hypoglycemic coma,diabetic ketoacidosis and hyperkalemia,and reviewed literature.Results The patient had hypoglycemia and acidosis at the same time due to taking phenformin and glibenclamide.After 2 days,the patient was better through correcting acidosis,intravenous fluid therapy,lowering blood potassium and controlling blood glucose.Conclusion Because acidosis caused the potassium transfer from intracellular to extracellular,the latter leads to hyperpotassemia,lactic acidosis caused by phenformin should be treated with intravenous fluid therapy,correcting acidosis.

Objective To evaluate the accuracy of Gallina nomogram in predicting seminal vesicle invasion (SVI) in prostate cancer.Methods From January 2009 to December 2011,89 patients with prostate carcinoma underwent open retropubic or laparoscopic radical prostatectomy.Complete data of preoperative serum prostate specific antigen (PSA),clinical stage,biopsy Gleason score,percentage of positive biopsy cores,pelvic MRI and pathological report of prostatectomy specimen were collected,and all the patients met the inclusion criteria of Gallina nomogram,2001 Partin tables and 2007 Partin tables.Postoperative pathological results were respectively compared with MRI and the incidence of SVI predicted by the three tools,and the sensitivity,specificity and accuracy of MRI in predicting SVI were calculated.The receiver operating characteristics curves were performed to test the predictive accuracy of SVI of each tool.Results The incidences of organ-confined disease,capsule invasion,SVI and lymph node metastasis were 58.4％,16.9％,22.5％,and 2.2％,respectively.The sensitivity,specificity and accuracy of MRI in predicting SVI was 45.0％ (9/20),71.0％ (49/69) and 65.2％ (58/89),respectively.The area under the curve (AUC) for SVI disease prediction of 2001 Partin tables,2007 Partin tables and Gallina nomogram was 0.712,0.711 and 0.801,respectively.Conclusions The sensitivity of MRI in predicting SVI is poor,the specificity and accuracy are common.All the predictive tools have a reasonable value for SVI (AUC ＞ 0.7),and Gallina nomogram is superior to two versions of Partin tables in predicting SVI.

Objective To summarize the clinical characteristics of 15 cases of Poland's syndrome and to explore the suitable treatment strategies. Methods A retrospective study of 15 adult patients with Poland's syndrome was conducted and the related literature was reviewed. According to the development of pectoralis muscles and breast, chest deformities were classified into 2 grades: mild and severe. Mild form was limited to absence of partial pectoralis major muscle, with variable hypoplasia of other minor components (such as the size of breast and the size and position of the nipple-areola complex), leading to a mild chest wall asymmetry. Severe form was characterized by absence or severe hypoplasia of the pectoralis major muscle and mammary gland with an evident chest wall asymmetry. Combined with gender, adult patients were divided into 4 types: female mild, female severe, male mild, and male severe. Each type had its own treatment strategies based on its anatomic features: silicone implant insertion for female mild type;latissimus dorsi muscular flap transposition and silicone implant insertion for female severe type;fat injection for male mild type;latissimus dorsi muscular flap transposition for male severe type of the patients. From 2003 to 2008, 15 adult cases were admitted to our ward, aged from 16 to 34 years.The case number of each type was 6, 6, 2 and 1, respectively. One severe female patients rejected any surgical interventions;the others were all treated as the above. Results Follow-up periods ranged from 6 months to 4 years. This series had got satisfactory results with good breast symmetry and natural texture. All the latissimus dorsi muscular flaps survived well. No postoperative complications, such as implant capsular contracture or implant displacement, were observed. Conclusion The manifestations of Poland's syndrome are extremely varied. This classification method is simple but useful, which could effectively direct the individualized treatment for the complete and adequate rehabilitation. Latissimus dorsi muscular flap, pedicled or free transplanted, pulsing silicone implant in females, are the first choices for severe chest deformations of this syndrome.

Objective To investigate the influence of the liposome PGE1 on the ischemia-reperfusion injury of the expanded flap.Methods The minipigs were set up as an animal model.They were divided into 2 groups.The expanded flaps (8 cm × 2 cm ) was designed and elevated on the back of the minipigs.An image analysis technology was used to evaluate the survival rate of the expanded flap,while a biochemistry method was used to detect the concentrations of malondialdehyde (MDA),myeloperoxidase (MPO) and microvessel density (MVD) in the tissue.Skin tempreture was measured after the drug administration.Results The survival area of the expanded flap in the Lipo PGE1 group was significantly enlarged (P＜0.05),compared with the control group.The MPO and MDA concen tration in the tissue was statistically different between two groups (P＜ 0.05),but there was no difference of the MVD concentration between two groups.The skin temperature was higher in the Lipo PGE1 group.Conclusions The Lipo PGE1 could promote survival rate in the expanded flap and protect it from ischemic injury.
