Abstract
In recent years, the consensus has confirmed the high lymph node metastasis rate of thyroid papillary cancer (PTC) and the characteristics of its sequential metastasis and intranodal metastasis. Guidelines for the diagnosis and management of thyroid nodules and differentiated thyroid cancer (second edition) proposed the concept of "selective lymph node dissection", a strategy that provides a promising outlook for endoscopic lateral neck dissection for PTC. Among various approaches, the transthoracic approach has been widely recognized for its simplicity, safety, feasibility, and wide range of indications. Years of practical exploration have shown that the four-zone seven-step selective dissection method through the transthoracic approach can achieve the same effect as open surgery without increasing the incidence of related complications. Therefore, for young patients with cosmetic needs, this operation has a very broad clinical prospective.

Abstract
The insulin growth factor 2 receptor (IGF2R) belongs to insulin growth factor (IGF) pathway and has been proposed as the tumor suppressor in many cancers. However, its role in bladder cancer is unknown. In the current study, we reported that IGF2R expression was decreased in bladder cancer tissues (p<0.05). Immunohistochemistry (IHC) and Cox regression analysis showed that low IGF2R expression was significantly associated with more advanced histological grade; high clinical stage; lymph node metastasis and poorer overall survival for patients with bladder cancer. Moreover, silencing IGF2R promoted cell proliferation of bladder cancer cells in vitro and in vivo (p<0.05). Furthermore, knockdown IGF2R resulted in higher phosphorylation level of AKT. The findings of this study indicated that IGF2R played a tumor suppressor role in bladder cancer. Downregulation IGF2R may promote tumor growth by activating AKT signaling pathway. IGF2R could be considered as a promising candidate for novel biomarker and therapeutic target for human bladder cancer.

Abstract
BACKGROUND Angiogenesis is a critical biological process essential for solid cancer growth and metastasis. It has been shown that microRNAs (miRNAs) play a vital role in a variety of biological processes in cancers. However, whether miR-130b is involved in prostate cancer angiogenesis remains ill-defined. METHODS We performed the miRNA microarray to analyze miRNA expression in human prostate cancer specimens. In vitro gain-of-function assays and loss-of-function assays were conducted to explore the potential functions of miR-130b in human prostate cancer cells. Correlation analysis and dual-luciferase reporter assay were performed to validate whether tumor necrosis factor-α (TNF-α) was a direct target of miR-130b. The Matrigel plug and tumor vascular imaging assays were performed to confirm the anti-angiogenic activity of miR-130b in nude mice. RESULTS We found that miR-130b was one of the miRNAs being most significantly downregulated. Subsequently, we found that miR-130b expression was markedly downregulated in human prostate cancer cell lines. Down-regulation of miR-130b in prostate cancer cells significantly promoted the proliferation, invasion and tubule formation of human umbilical vein endothelial cells (HUVECs), while ectopic expression of miR-130b blocked prostate cancer angiogenesis in vitro and in vivo. Mechanistic analyses indicated that tumor necrosis factor-α (TNF-α) was regulated by miR-130b directly. MiR-130b attenuated nuclear factor-κB (NF-κB) signaling and its downstream gene vascular endothelial growth factor-A (VEGFA) by directly inhibiting TNF-α expression. Additionally, subsequent investigations identified that the ectopic level of VEGFA markedly abrogated the anti-angiogenic effect induced by miR-130b. Interestingly, VEGFA could in turn decrease the expression of miR-130b, thus forming a negative feedback loop that drives the angiogenesis of prostate cancer. CONCLUSION These findings show that miR-130b/TNF-α/NF-κB/VEGFA feedback loop is significantly correlated with angiogenesis in prostate cancer and miR-130b could be regarded as potential therapeutic target for prostate cancer anti-angiogenesis treatment.

Abstract
Objective: To summarize the preliminary experience with transoral endoscopic thyroidectomy via vestibular approach (TOETVA). Methods: A total of 150 consecutive patients with thyroid disease underwent TOETVA from November 2014 to February 2017 at Department of Thyroid Surgery, the Second Affiliated Hospital of Zhejiang University School of Medicine. The patients were comprised of 138 females and 12 males. The mean age of the patients was (31.7±7.6) years (ranging from 15 to 51 years). There were 108 patients of differential thyroid carcinoma (T1 or T2 ≤3 cm, cN0 or cN1a, M0) and 42 patients of benign thyroid disease (solid nodule ≤6 cm). The criteria analyzed were clinicopathologic characteristics, types of operation, operation time, complications and results of follow-up. Results: Two cases were converted into open surgery due to an incredible unexpected tumor size and tracheal invasion, respectively. One hundred and three patients with papillary carcinoma underwent transoral central neck dissection (CND), with the mean operation time of (146±34) minutes for hemithyroidectomy with CND, and (187±36) minutes for total or near total thyroidectomy with CND. The mean number of lymph node yields was 8.2±4.7, and the lymph node metastasis rate was 41.7% (43/103). Regarding postoperative complications, transient hoarseness occurred in 3 patients, and permanent recurrent laryngeal nerve occurred in 2 patients. One patient had local infection or transient mental nerve palsy. Transient hypocalcemia occurred in 31.8% of 22 patients who underwent total, near-total, or subtotalthyroidectomy, and no permanent hypocalcemia was registered. Mean hospital stay after operation was (3.5±0.6) days (ranging from 2 to 5 days). Mean follow-up period was (11.5±7.8) months (ranging from 1 to 28 months), no recurrence or metastasis occurred. Conclusions: TOETVA is feasible and safe for strictly selective patients. It brings perfect cosmetic effect. Long-term follow-up and further study is needed to assess its curative effect.

Abstract
Objective: To evaluate the predictive accuracy of fine needle aspiration (FNA) and BRAF V600E mutation in distinguishing papillary thyroid carcinoma and other thyroid nodules. Methods: This retrospective cohort study included 93 patients with papillary thyroid carcinoma who treated at Department of Thyroid Surgery, the Second Affiliated Hospital of Zhejiang University, College of Medicine from September 2016 to May 2018. There were 21 males and 72 females with age of (43.2±11.3) years (range: 19 to 67 years). All the patients got the examinations of FNA and BRAF V600E mutation by Amplification Refractory Mutation System, and subsequently underwent thyroid surgeries. The results of cytopathology, frozen section and pathology were collected and analyzed. The predictive accuracy of FNA cytology and BRAF V600E mutation was calculated. Results: In the 93 collected cases, 91 were diagnosed as papillary thyroid carcinoma postoperation, and the accurate predictive rate was 97.8%. Subgroup analysis was performed according to Bethesda System, the predictive rates were: unsatisfactory (Ⅰ) 6/6, benign (Ⅱ) 0/0, atypia of undetermined significance or follicular lesion of undetermined significance (Ⅲ) 16/17, follicular neoplasm or suspicious for follicular neoplasm (Ⅳ) 97.2% (35/36), suspicious for malignancy (Ⅴ) 100% (28/28), and malignant (Ⅵ) 6/6, respectively. Conclusion: Thyroid nodules with BRAF V600E mutation can be strongly speculated as papillary thyroid carcinoma.
