| 1 | Clinical applications of free medial tibial flap with posterior tibial artery for head and neck reconstruction after tumor resection显示文摘Tumor resection causes damage in the head and neck which creates problems in swallowing, chewing, articulation,and vision, all of which seriously affect patients' quality of life. In this work, we evaluated the application of a free medial tibial flap in reconstruction of head and neck defects after tumor resection. We discussed the anatomy,surgical technique, and the advantages and disadvantages of the flap. We found several benefits for the flap, such as,it is especially effective for the defects that require thin-layer epithelium to cover or the separated soft tissue defect;a two-team approach can be used because the donor site is far away from the head and neck; and the flap is easy to integrate because of the subcutaneous fat layer of the free medial tibial flap is thin and the flap is soft. Thus, the medial tibial flap could replace the forearm flap for certain applications. | Qi Zhong Jugao Fang Zhigang Huang Xiaohong Chen Lizhen Hou Yang Zhang Pingdong Li Hongzhi Ma Hongbo Xu | 2017 | Chinese Journal of Cancer Research2017，29，3： | 5 |
| 2 | Differential transcriptome analysis between Populus and its synthesized allotriploids driven by second-division restitution显示文摘In this report, we compared transcriptomic differences between a synthetic Populus section Tacamahaca triploid driven by second-division restitution and its parents using a high-throughput RNA-seq method. A total of 4,080 genes were differentially expressed between the high-growth vigor allotriploids(SDR-H) and their parents, and 719 genes were non-additively expressed in SDR-H. Differences in gene expression between the allotriploid and male parent were more signi ficant than those between the allotriploid and female parent, which may be caused by maternal effects. We observed3,559 differentially expressed genes(DEGs) between the SDR-H and male parent. Notably, the genes were mainly involved in metabolic process, cell proliferation, DNA methylation, cell division, and meristem and developmental growth. Among the1,056 DEGs between SDR-H and female parent, many genes were associated with metabolic process and carbon utilization.In addition, 1,789 DEGs between high- and low-growth vigor allotriploid were mainly associated with metabolic process,auxin poplar transport, and regulation of meristem growth.Our results indicated that the higher poplar ploidy level can generate extensive transcriptomic diversity compared with its parents. Overall, these results increased our understanding of the driving force for phenotypic variation and adaptation in allopolyploids driven by second-division restitution. | Shiping Cheng Zhen Huang Yun Li Ting Liao Yujing Suo Pingdong Zhang Jun Wang Xiangyang Kang | 2015 | Journal of Integrative Plant Biology2015，57，12： | 3 |

| 4 | Factors contributing to lymph node occult metastasis in supraglottic laryngeal carcinoma cT2-T4 N0M0 and metastasis predictive equation显示文摘Objective: To investigate factors that contribute to lymph node metastasis(LNM) from clinical cT2-T4 N0M0(cN0) supraglottic laryngeal carcinoma(SLC), and to predict the risk of occult metastasis before surgery.Methods: A total of 121 patients who received surgery were retrospectively analyzed. Relevant factors regarding cervical LNM were analyzed. Multivariate analyses were conducted to predict the region where the metastasis occurred and prognosis. Results: The overall metastatic rate of c N0 SLC was 28.1%. Metastatic rates were 15.4%, 32.5% and 35.7% for T2, T3 and T4, respectively. Metastatic rates for SLC levels II, III and IV were 19.6%, 17.2% and 3.6%, respectively. A regression equation was formulated to predict the probability of metastasis in cN0 SLC as follows: Pn=e(–3.874+0.749T3+1.154T4+1.935P1+1.750P2)/[1+e(–3.874+0.749T3+1.154T4+1.935P1+1.750P2)]. Approximately 0.2% of patients experienced LNM with no recurrence of laryngeal cancer. Comparison of the intergroup survival curves between patients with and without LNM indicated a statistically significant difference(P=0.029).Conclusions: Cervical lymph node metastatic rates tended to increase in tandem with T stage in patients with LNM in cN0 SLC, and neck dissection is advised for these patients. Moreover, cervical LNM in cN0 SLC showed a sequential pattern and may be predicted. | Hongzhi Ma Meng Lian Ling Feng Pingdong Li Lizhen Hou Xiaohong Chen Zhigang Huang Jugao Fang | 2014 | Chinese Journal of Cancer Research2014，26，6： | 1 |
