Objectives: To study the e ect of human P27KIP1 gene AVV virus combining with Chinese herb Pien Tze Huang on human osteosarcoma mice model. Methods: 40 standardized human osteosarcoma mice model were divided into 5 groups, treated with PBS, Paav-MCS, human P27KIP1 gene AVV virus, Chinese herb Pien Tze Huang or human P27KIP1 gene AVV virus combining with Chinese herb Pien Tze Huang in each di erent group. Results: ① Mice model of transplant human osteosarcoma were established successfully. ②Osteosarcoma were inhibited successfully by human P27KIP1 gene AVV virus, Chinese herb Pien Tze Huang or human P27KIP1 gene AVV virus combining with Chinese herb Pien Tze Huang. ③Mice model of transplant human osteosarcoma were active during observation. Conclusions: ①These results suggested that human P27KIP1 gene AVV virus, herb Pien Tze Huang and human P27KIP1 gene AVV virus combined with herb Pien Tze Huang were e ective on human osteosarcoma. ②Among them, the most e ective treatment was human P27KIP1 gene AVV virus combining with herb Pien Tze Huang. ③Chinese herb Pien Tze Huang was possible useful for life improvement of osteosarcoma patient.

Objective:To discuss the principle and effect of augmentation rhinoplasty with auricular cartilage and expanded polytetrafluoroethylene.Methods:From January 2018 to January 2020, 161 patients (10 males and 151 females; aged from 19 to 48 years, with an average of 26 years) underwent " auricular cartilage plus expanded polytetrafluoroethylene" augmentation rhinoplasty in Nanfang Hospital of Southern Medical University. The expended polytetrafluoroethylene was carved into a willow leaf shape (I Shape) to fill the nasal dorsum, and the cartilage taking from cymba concha was constructed into an arched bridge shape for the nasal tip shaping. Pre-operative and 1-year post-operative measurements nasal length, nasal height, nasal depth, nasal columella height, nasal tip width, nasofrontal angle, nasolabial angle, survey of satisfaction and complication rate 1-2 years after operation were taken. The statistical analysis of nasal morphological indicators and nasal aesthetic indicators were employed.Results:The nose shape of 161 patients was improved to varying degree. All morphological indicators were improved, and difference was statistically significant ( P<0.05). The nasofrontal angle reached the standard in 90 cases, accounting for 55.9%; The nasolabial angle reached the standard in 143 cases, accounting for 88.8%. 2 cases had prosthesis (ePTFE) deviation and were corrected by surgical repair; 1 case had prosthesis (ePTFE) rejection and was corrected by prosthesis (ePTFE) removal surgery. Conclusions:Corresponding to the anatomical characteristics of the external nose, the prosthesis material is designed and made to correspond to the dorsum shape of the nasal stent. The shape of the alar cartilage, the prefabricated arched bridge shape of the cymba concha cartilage are used to reconstruct the nasal tip, which can effectively elevate the nasal dorsum, improve the protruding degree and rotation degree of the nasal tip, and have good long-term support. The flexibility and activity of the nasal tip are similar to the biological nose.
