Carbon ion radiotherapy for recurrent ameloblastoma: A case report.

Ameloblastoma is a kind of benign, odontogenic tumor of epithelial origin, and surgery is mainstay treatment method; however, recurrence is common, and usually the treatment for recurrence is still surgery. We report on a patient of recurrent ameloblastoma treated with carbon ion radiation therapy and achieved a good efficacy. A 25-year-old female with relapse of an ameloblastoma was referred to the Wuwei Heavy Ion Center for carbon ion therapy.

Upregulation of miR-519 enhances radiosensitivity of esophageal squamous cell carcinoma trough targeting PI3K/AKT/mTOR signaling pathway.

Purpose: MicroRNA-519 (miR-519) has been previously reported to function as a tumor suppressor in several types of malignancies. This study aimed to probe the biological role of miR-519 in esophageal squamous cell carcinoma (ESCC).

Methods: qRT-PCR was utilized to test the miR-519 expression level in ESCC tissues and cells.

Cryptotanshinone inhibits lung cancer invasion via microRNA-133a/matrix metalloproteinase 14 regulation.

Cryptotanshinone inhibits the proliferative and colony formation abilities of human non-small cell lung cancer cells (NSCLCs). The present study reported that signal transducer and activator of transcription 3 is not the only target of cryptotanshinone during the inhibition of human NSCLCs. It was identified that cryptotanshinone upregulates the expression levels of microRNA (miR)-30d-5p, miR-126-3p, miR-133a, miR-338-3p and miR-451a, and downregulates miR-21-5p, miR-96-5p, miR-182-5p and miR-205-5p.

LINC00473/miR-374a-5p regulates esophageal squamous cell carcinoma via targeting SPIN1 to weaken the effect of radiotherapy.

Esophageal squamous cell carcinoma (ESCC) is the most prevalent type in esophageal cancers. Despite accumulating achievements in treatments of ESCC, patients still suffer from recurrence because of the treatment failures, one of the reasons for which is radioresistance. Therefore, it is a necessity to explore the molecular mechanism underlying ESCC radioresistance.

LBX2-AS1 is activated by ZEB1 and promotes the development of esophageal squamous cell carcinoma by interacting with HNRNPC to enhance the stability of ZEB1 and ZEB2 mRNAs.

Long non-coding RNAs (lncRNAs) are a group of transcripts, which can regulate the progression of esophageal squamous cell carcinoma (ESCC). According to the data of TCGA, Ladybird homeobox 2 antisense RNA 1 (LBX2-AS1) is a highly expressed lncRNA in ESCC samples. Herein, we chose it for further study.

Practice of cervical end-esophageal exteriorization in patients with severe intrathoracic anastomotic leakage after esophagectomy.

Objective: This study aimed to summarize the clinical experience of severe intrathoracic anastomotic leakage encountered in clinical practice by using cervical end-esophageal exteriorization.

Methods: We undertook a retrospective review of four patients who developed severe anastomotic leakage after subtotal esophagectomy at our department. Four patients with a life-threatening condition and failed conservative management were re-operated on from the original incision using an exteriorized cervical end-esophageal gastric conduit.
