Thyroidectomy Using the Lateral Cervical Small Incision Approach for Early Thyroid Cancer.

Objective: Surgical resection is the main treatment for thyroid cancer, but while traditional open thyroidectomy improves prognosis, it also results in poor cosmetic outcomes. Therefore, we devised the lateral cervical small incision approach to thyroidectomy and will evaluate its efficacy.

Methods: The clinicopathological data of 191 patients who underwent unilateral thyroidectomy and isthmusectomy for early thyroid cancer were collected retrospectively.

The role of microRNA-4723-5p regulated by c-myc in triple-negative breast cancer.

The aim of this study was to investigate the expression of miRNA regulated by c-myc and its mechanism in three negative breast cancer (TNBC). We constructed MDA-MB-231 cell line with low expression of c-myc by lentivirus short hairpin RNA (shRNA), analyzed the miRNA expression profile of MDA-MB-231 cell line with different expression levels of c-myc by high-throughput sequencing technology, obtained differential miRNA by bioinformatics analysis and statistical analysis, and verified hsa-mir-4723-5p by Quantitative Real-time polymerase chain reaction(QRT-PCR). The target gene of hsa-mir-4723-5p was analyzed by miRDB and miRWalk database.

[Prokaryotice expression of the NS1 gene of PPV and renaturation of the recombinant protein].

The antigen of NS1 gene of PPV was amplified by PCR, and the amplified fragments were cloned into the prokaryotic expression vector pGEX-4T-1. The insert position, the size and the frame were identified by PCR, restriction enzyme digestion and the sequence analysis of the recombinant plasmids. The sequence analysis results of pGEX-NS1-HN1 showed that the prokaryotic expression vector was successfully constructed.

[Construction of the eukaryotic expression vector with IL-2 gene and VP2 gene of PPV and research on immunogenicity].

To construct gene vaccine of PPV and to investigate the effects of interleukin 2 (IL-2) as an adjuvant on immune responses in mouse, the recombinant expression plasmid of pCIneo-IL2-VP2 was constructed and transfected into PK-15 cells by lipofectamine, the expressed product was detected by immunofluore assay. To study the immune effects of DNA vaccine in vitro and in vivo, mice were used as the animal model. The recombinant plasmid pCIneo-IL2-VP2, the control plasmid pCI-neo and the PPV live vaccine were immunized by intramuscular injection.
