Abstract
Objective: To investigate the feasibility, efficacy and safety of semiconductor laser in situ fenestration of type A aortic dissection during thoracic endovascular aortic repair. Methods: The clinical data of 68 patients with type A aortic dissection treated by semiconductor laser in situ fenestration from June 2016 to January 2020 in Department of Vascular Surgery, Shanghai Ninth People's Hospital Affiliated to Shanghai Jiaotong University were analyzed retrospectively. Of the patients, 45 were male, 23 were female, the mean age was (52±14) years. The technical success rate and complication rates were assessed. Results: The technical success rate of 68 patients was 92.6% (63/68), only 5 patients failed due to the complex aortic arch type, 3 patients underwent chimney stent implantation, 2 patients underwent artificial vessel bypass. During the perioperative period, 1 patient died due to severe pulmonary infection, 4 patients developed neurological symptoms such as cerebral infarction after surgery, and the remaining patients had no related complications. Postoperative CTA follow-up indicated that the primary intercalation rupture was completely closed, and the main and branch stents were patency, 8 (8.8%) type Ⅰ leakage were occurred. Conclusion: It showed that in situ semiconductor laser fenestration is a feasible, effective and safe method to treat type A aortic dissection.

Abstract
Objective: To observe the effect of KLF3 on the expression of STAT3 in breast cancer cells, and to explore the potential mechanism of KLF3 affecting the movement, migration and invasion of breast cancer cells. Methods: Firstly, the expression of STAT3 was detected by Western blot, real-time fluorescent quantitative PCR, luciferase reporter system and chromatin immunoprecipitation in breast cancer cells. Secondly, the STAT3 promoter mutant was constructed. The plasmid further confirmed the effect of KLF3 on the activity of STAT3 promoter; the cell scratching test and Transwell method were used to detect the ability of cell movement, migration and invasion. Finally, animal experiments were conducted to verify the effect of knockdown of KLF3 on tumor metastasis in animals. Results: In breast cancer cells, knockdown of KLF3 promoted STAT3 protein expression. The mRNA level of STAT3 was increased by (3.58±0.65) fold after knockdown of KLF3 in MDA-MB-231 cells, while the mRNA level of STAT3 was increased by (2.28±0.19) fold after KLF3 knockdown in MCF-7 cells (P<0.001). KLF3 boundto the promoter region of STAT3. The transcriptional activity of STAT3 increased by (2.47±0.87) fold after knockdown of KLF3 in MDA-MB-231 cells, while the transcriptional activity of STAT3 increased by (2.63±0.65) fold after KLF3 knockdown in MCF-7 cells, P<0.01. KLF3 knockdown inhibitedthe movement,migrate and invade of breast cancer cells. Based on this, silence STAT3 partially reversed the function of KLF3. Knockdown of KLF3 promotedtumor metastasis in mice. Conclusions: KLF3 knockdown can promote the transcriptional activity of STAT3, which promotes the protein expression of the latter. KLF3 can affect the movement, migration and invasion of breast cancer cells through STAT3. KLF3 may be a potential target for the treatment of metastatic breast cancer.

Abstract
With the continuous development of endovascular surgery, thoracic endovascular aortic repair (TEVAR) has gradually replaced traditional open surgery and has become the preferred treatment strategy for Stanford type B aortic dissection. However, the disadvantage of the short proximal landing zone greatly limited the indication of TEVAR surgery and affected the prognosis. In recent years, many strategies such as hybrid surgery, in vitro fenestrated and branched aortic endo-graft, chimney technique, in-situ fenestration technique, etc., have been developed, which greatly broadens the TEVAR indication and improved the prognosis.

Abstract
Genetic manipulation using linear DNA was applied to the common wheat variety Xindong No. 26 via particle bombardment with the aim to improve bread-making quality of flour. Initially, 2 biolistic parameters, helium pressure and target distance, were optimized using plasmid pAHC25. We transformed wheat immature embryo scutella with the linear 1Dx5 gene without selectable markers. The highest transient β-glucuronidase expression was obtained when scuttles were bombarded at 1100 psi with a 9-cm target distance. Using the optimized parameters, the transformation of the common wheat variety Xindong No. 26 was carried out using the linear 1Dx5. Three transgenic plants were identified from 1003 transgenic plants, yielding a transformation frequency of 0.4%. A sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis confirmed that the 1Dx5 gene was expressed in 4 T1 seeds of the transgenic plants. These experiments indicate the possibility of obtaining marker-free transgenic wheat plants via particle bombardment using the minimal gene cassettes with the particle bombardment parameters.
