Objective To observe the effects of secreted protein,acidic and rich in cysteine (SPARC) on the expression of TGF-β1 and collagen type Ⅰ in cultured human keloid fibroblasts by real-time fluorescence quantitative RT-PCR.Methods In vitro keloid fibroblasts were stimulated by different concentrations of recombinant human SPARC,and with the control group for comparison,real-time fluorescence quantitative RT-PCR to detect expression of TGFβ1 and collagen type Ⅰ.Results Compared with the control group,the expression of TGF-β1 and collagen type Ⅰ was significantly increased in the experimental group.Conclusions SPARC could enhance the expression of TGF-β1 and collagen type Ⅰ in keloid fibroblasts significantly.
2. Supra-auricular flap and stretch of scapha cartilage: a method of cryptotia′s treatment
Chinese Journal of Plastic Surgery 2018;34(9):732-734
Objective:
To explore a simple method of cryptotia correction with good effect.
Methods:
7 patients and 10 ears were operated on, using a supra-auricular V-Y flap. The auricular muscles′ adhesion with cartilage was sufficiently released, and the scapha cartilage was remodeled by a reverse suture. The flap was rotated to post-auricular to close the wound, and deepenen the auriculocephalic angle.
Results:
All patients′ ears nearly had a normal appearance and an obvious crus of helix. Patients could wear glasses or respirator easily, as their supra-auricular part was free from the skull. Our technique ensured all scars were hidden behind the ear or in the hair. No patients required revisional surgery.
Conclusions
This technique is a simple method , which has a good result , covert scar and low recurrence. We can use it for majority of patients with cryptotia.

Objective:
This study aimed to present our clinical experience using a novel method for autologus costal cartilage framework fabricationin fully expansion technique ear reconstruction without skin graft.
Methods:
During Steptember 2016 to Steptember 2017, autologus costal cartilage framework with expansion technique were performed for 63 patients with microtia. Autologous costal cartilage was stacked up to form the structure and height, the natural appearance of auriculocephalic angle was achieved at the same stage, so the second-stage elevation of ear and postauricular skin graft was unnecessary. The delicate structure of the reconstructed ear and ideal bilateral symmetry were achieved by the optimized cartilage stack-up.
Results:
Three patients out of total 63 patients had cartilage frame work exposure, and were treated with superficial temporal fascia transfer combined with skin graft. The rest 60 patients had satisfied results. Follow-up ranged from 8 months to 18 months and 12 months follow-up was on average. The novel frame work fabrication method was based on the sufficient full pre-expansion procedure. The ideal structure, bilateral symmetry, and excellent definition of the framework, as well as the natural dorsal appearance of the reconstructed auricular were achieved.
Conclusions
The cartilage " stack-up" method is essential for the full expansion without skin grafts ear reconstruction technique. The combination of the cartilage " stack-up" framework fabrication and full pre-expansion provide a well-defined, well-projected and bilateral symmetrical ear.

Objective:
To investigate the clinical effect of conjoint fascial sheath (CFS) suspension to correct the complications caused by the frontal muscle flap suspension and levator palpebrae superioris shortening in the treatment of severe blepharoptosis.
Methods:
From February 2017 to April 2018, 19 severe blepharoptosis patients (21 eyelids) were operated before by the frontal muscle flap suspension and levator plapebrae superioris shortening, and repaired through the technology of CFS suspension.
Results:
There were 19 cases, 17 cases operated by CFS suspension showed a good appearance and basically symmetrical of two eyes, and the other 2 cases obtained satisfactory results though reoperation. There were no complications of exposure keratitis, ectropion and infection occurred. Meantime the effect was satisfactory according to the follow-up ranging from 3 months to 12 months.
Conclusions
The application of conjoint fascial sheath (CFS) suspension shows a promising procedure in the treatment of severe blepharoptosis caused by the frontal muscle flap suspension and levator palpebrae superioris shortening.

Objective:
To evaluate the application of the expanded free deltopectoral flap, pedicled with perforation of internal thoracic artery, in the repairment of middle to large facial skin and soft tissue defect.
Methods:
From June 2015 to December 2017, 11cases diagnosed with facial lesions were included in this study. The tissue defect of 10 cases were caused by burn, and 1 case by superficial tumor. In the first stage, the tissue expander was implanted into the internal thoracic artery supplying area. After the expander was fully expanded, the second surgery, i. e. the resection of facial lesion, was performed. The defect areas of patients, with the range of 9 cm×7 cm to 17 cm×10 cm, were repaired by expanded free deltopectoral flaps.
Results:
All flaps were survived, with no vascular crisis occurred. The size of flaps ranged from 10.0 cm×9.0 cm to 18.0 cm×11.5 cm. All the patients were satisfied with the outcomes, after 6 to 24 months follow-up. The color and texture of flaps was close to normal. The scars were acceptable.
Conclusions
The expanded free deltopectoral flap, pedicled with the perforator of internal thoracic artery, is a promising way to repair middle to large facial skin and soft tissue defect.

Objective:
This study aimed to present our clinical experience of the utilization of remnant ear for the inferior part and lobule reconstruction in microtia patient with the fully pre-expansion ear reconstruction technique.
Methods:
During 2017.01—2018.12, 156 cases of unilateral ear reconstruction were performed. The operation was divided into three stages. Six months after the ear reconstruction, the third stage of the remnant ear utilization was performed. The surgery was planned according to the microtia classification and the remnant morphology.
Results:
All the patients had no complications. Follow-up period ranged from 7—24 months, and ten months on average. All the patients with typeⅠmicrotia had satisfying results of the inferior part and lobule reconstruction. Sixteen cases of types Ⅱand Ⅲ microtia patients had unfortunate outcomes, because the residual ears were too small to reconstruct the earlobe, and the incisure appeared when remnant and reconstructed ear was connected in cases of severe remnant malposition. The rest of patients were satisfied with the reconstruction.
Conclusions
The utilization of the remnant ear based on the types of microtia and the remnant morphology could achieve the satisfying result of reconstruction for most of the microtia patients.
