Objective To evaluate the clinical efficacy of the application of auricular composite tissue flap in treatment of nasal alar de-fect. Methods 43 cases of nasal defects patients were admitted to our hospital from January 2008 to March 2013, 23 cases of them were treated with auricular composite tissue flap transplantation, and the other 20 cases were given nasolabial sulcus flap transfer operation. All patients were followed-up for 6 to 12 months, and the rate of secondary surgery, proliferation of scar, and flap survival of the two groups were compared. Results Treatment of auricular composite tissue flap transplantation has more advantages in terms of the rate of secondary surgery, proliferation of scar, and flap survival, and the difference is of statistical significance (P<0. 05). And there is no obvious differ-ence in satisfaction degree of cosmetic outcomes. Conclusion Auricular composite tissue flap surgery has the advantages of simple opera-tion, good appearance and good efficacy.

Objective To discuss the clinical manifestation and treatment of the complications caused by injected polyacrylamde hydro-gel( PAAG) for breast augmentation. Methods This retrospective research was performed among 212 patients who undergoing breast aug-mentation with injected polyacrylamde hydrogel. The clinical manifestation and treatment outcome of the complications were analyzed and summarized,which is aim to search an effective treatment method. Results For the 212 patients,the main complications were breast multi-ple indurations (131 cases),fever (9 cases),infection (14 cases),breast pain (65 cases),PAAG displacement (28 cases) and secondary deformity or asymmetry (25 cases). 152 cases experienced one clinical symptom,the rest patients simultaneously undergone no less than two clinical symptoms. Patients were received open operation with periareolar incision ( surgery group) or vacuum absorption by needle ( aspira-tion group) for dislodging PAAG. No significant difference was found in wound healing,breast shape satisfaction and pain anesis between the two groups. Whilethe surgery group was better than the aspiration group in efficiency for taking out PAAG and the incidence of reoperation, with statistical significance. Conclusion A plenty of complications occurred after breast augmentation with injected polyacrylamde hydrogel, the method of open operation with periareolar incision is a better way for eliminating PAAG and treating the complications.

Objective To investigate the role of heat shock protein 70 (HSP70) in liver flbrosis in infants with biliary atresia (BA) and its impact on prognosis. Methods Fourty-six (46) cases of infants with BA undergoing elective Kasai surgery were selected. In the same period, 30 cases of children with choledochal cyst and 17 cases of children with portal vein cavernous transformation were selected. The expressions of HSP70 in liver tissues were detected using immunohistochemical staining. The liver flbrosis in children with BA was detected using Sirius red-saturated picric acid staining. The expressions of HSP70 proteins in different flbrotic liver tissues were detected by using double staining. All postoperative BA infants were followed up and ended at June 30, 2016.Results The proportion of high expression of HSP 70 proteins in BA infants were signiflcantly higher than that in children with choledochal cyst and vein cavernous transformation (P<0.05). Rank correlation analysis showed that the expressions of HSP70 in liver tissues were positively correlated with the degree of liver flbrosis (r=0.861,P<0.05). 15 patients died among 46 cases of BA infants. The survival rate in BA children with mild liver flbrosis was 82.4%, which was signiflcantly higher than 58.6% in the severe group (P<0.05). The survival rate in HSP70 protein low expression group was 85.0%, while in HSP70 protein high expression group was 53.8%. Kaplan-meier survival analysis showed that the median survival time in the HSP70 protein low expression group was (34.0±2.6) months, while in the HSP70 protein high expression group was (18.3±2.2) months, the difference was statistically signiflcant (χx2=4.765,P=0.029).Conclusions The expressions of HSP70 proteins in liver tissues in infants with BA were high and were positively correlated with the degree of hepatic flbrosis. It suggested the possible involvement of HSP70 in the process of liver fibrosis. The upregulated expressions of HSP70 often indicated poor prognosis in children. It could be used as determining biomarker for prognosis.
