Aim To prepare and identify monodonal sntibody (Mab) specific for Toaoplasma gondii tachyzoites. Method The Mab specific for Taxoplasma gondii tachyrzoite were prepared via bybridoma technique. Indirect ELISA was used to determine the activity of the Mab. Agarose double immuodiffusion test was performed to confirm subclass and SDS-PAGE & western blot were used to analysis rolecular weight of the antigen (s) recognized by the Mab. IFA was used to identify the epitope of Taxoplasma gondii tachyzoites. The protection and specificity of the Mab were snalysed at same time. The Mab was tesed in Mab-ELISA method to detect Taxoplasma gondii antigen. Results A Msb F7C8H12 specific for T. gondii was produced. It belongs to IgG1 subclass. Moleculsr weight of the sntigens recognized by the Mab was 16.5 and 24 kDa. IFA did not show fiuorescence in intact tachyzoite.Inhibition test showed that the inhibition rate was 50% when the concetration of the antigen was 40μg/ml.Afterthe RH strain tachyzoites were incubated with Mab ascites, mice were inected with the tachyzoites through peritoneum. The results showed that the mean dead time of mice were not delayed. T. gondii antigen mixed with PBS snd normal human serum was detected by Mab-ELISA, the sensitvity was 0.78 yg/ml and 1.5μg/ml respectively. When mice were infected with T. gondiiRH strain tachyzoites, 103/mouse p.i., circulating antigen could be detectedin 6 day and 8 day. Conchusion The Mab (F7C8H12) to T. gomdii tachyzoites is an excellent probe for studying T. gondii snd toxoplasmosis.

Objective To compare the perinipple round-block technique with the conventional periareolar round-block technique in areolar reduction operations.Methods A total of 37 patients who underwent areolar reduction operations in our department were randomly allocated into two groups:Group A (19 patients) received a conventional periareolar round-block technique,while group B (18 patients) through a new perinipple round-block technique.In the latter approach,an intraareolar donut of pigmented skin was deepithelialized,and the exposed areolar dermis was then telescoped inward and stretch-anchored to an imaginary circular line situated beneath the breast skin areola junction.The roundblock technique was then utilized to approximate the skin edges,resulting in a minimal scar,totally inconspicuous,confined to the immediate perinipple area.The operative time,perioperative complications,scars,absorption time of the skin folds,the sensation of the nipple-areolar complex and the patients' satisfaction were compared between the two groups.Results The mean operative time of group A and group B was 40.5 min and 45.8 min,respectively (P＜0.05).No perioperative complications were found in these two groups.No patient had experienced permanent nipple sensory changes.The skin folds absorption time of group A was 4.34 months,while the time of group B was 8.78 months (P＜0.01).The perinipple round-block technique produced a more inconspicuous scar with a better aesthetic results.Conclusions The traditional periareolar round-block technique leaves a sharply demarcated areola by a circular scar which has a totally unnatural and artificial look.As for the perinipple round-block technique,the incision as well as any residual cutaneous wrinkling or puckering is well concealed by the dome of the nipple and the areolar,but it needs a longer skin folds absorption time.

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 To explore the clinical effect of the modified rhytidectomy technique with hidden temporal and buccal incision.Methods 26 cases of aging face were collected.The operation was performed with modified preauricular incision which was the leading edge of the cartilage of helix and hair line.Preauricular remporal fascia was modified as suspended vertically and SMAS superficial to parotic gland was suspended vertically to nasolabial sulcus.Results All the patients reported fine rejuvenescent effects,the satisfaction rate was 100％ without any severe complications,such as scar,hair loss on temperal incision.Conclusions This surgical technique may maintain natural configuration of preauricular area,result in invisable incision scar with no obvious baldness,and avoid important nerves or vessel injury.

OBJECTIVETo evaluate the efficacy and risksof the treatment of facial acne scar with dermabrasion combined with Recell® technology.

METHODS30 patents with II or III degree facial acne scars were treated with dermabrasion and Recell® (skin active cell transplantation) technique in our department from October 2010 to October 2011. The affected area in the face was dermabraded with micro motor system. Then a small piece of razor-thickness skin graft was obtained and processed with Recell® kit. Several milliliterof autologous uncultured epidermal cell suspension was applied to the facial wound and covered with appropriate dressings.

RESULTSTheeffectiveness and risks of this treatment was evaluated with regard to wound healing time, postoperative complication rate, erythema period, etc. Wound healing time was shortened to 5-7 days. The erythema period was also observed shortened with this technique. Within the follow up period, no hyperpigmentation was reported in this case serial.

CONCLUSIONDermabrasion combined with Recell® (skin active cell transplantation) technology can provide a safety and effective treatment approach for patients with facial acne scars.

OBJECTIVETo investigate the feasibility of immediate breast and nipple-areola reconstruction after skin-sparing mastectomy.

METHODS24 patients who received skin-sparing mastectomy underwent immediate breast reconstruction with or without breast implants. The nipple-areola complex is also reconstructed with the skin paddle of the latissimus dorsi flap in one stage.

RESULTSAll the latissimus dorsi myocutaneous flaps survived completely. Partial necrosis happened in two reconstructed nipples which healed after dress changing. The follow-up period ranged from 6 to 12 months. 3 patients presented with capsular contracture (Baker I), with no necessary of surgical revision. The retraction rate of reconstructed nipples projection is 35.4% at 6 months postoperatively and 38.6% at 12 months postoperatively. 91.7% of patients were satisfied or very satisfied with the breast shape, while 83.3% were satisfied or very satisfied with the breast volume. All the patients considered the reconstructed nipple very good, while 91.6% were satisfied with the nipple projection. 91.7% considered immediate nipple reconstruction to be very important, and 8.3% considered it to be important. 66.7% considered the new breast could replace the breast they had lost, and 8.3% considered that it could not.

CONCLUSIONFor skin-sparing mastectomy, immediate breast and nipple reconstruction can achieve good aesthetic results.

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 evaluate the preliminary outcome of stable vitiligo treatment with ReCell(R )technique.Methods Six patients with stable vitiligo were treated with ReCell(R ) technique.In each patient,a thin razor-thickness cutaneous biopsy was harvested from uninvolved area near the vitiligo patches.It was then processed through the ReCell(R ) system and 1 ml autologous epidermal cell suspension was obtained.The lesion area was dermabraded using a diamond fraise wheel to the dermoepidermal junction.The cell suspension was then sprayed on the wound and covered with non-adhering dressings.Results The patients were followed up for 6 months.5 patients presented with repigmentaion in the treated area.There was no significant response in one patient who was diagnosed as systematic vitiligo.Conclusions The ReCell(R ) technique is an alternative treatment for stable vitiligo patients.The clinical outcome will be satisfactory when appropriate patients are selected.

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.
