Discontinuous Versus In-Continuity Neck Dissection in Squamous Cell Carcinoma of the Tongue and Floor of the Mouth: Comparing the Rates of Locoregional Recurrence.

Purpose: To date, consensus has not been reached on which treatment modality, that is, in-continuity neck dissection or discontinuous neck dissection, is more appropriate for managing patients with squamous cell carcinoma (SCC) of the tongue and floor of the mouth. This study aimed to perform a meta-analysis to compare discontinuous neck dissection with in-continuity neck dissection as a treatment modality for SCC of the tongue and floor of the mouth.

Materials And Methods: The PubMed, Web of Science, China National Knowledge Infrastructure, and Wanfang databases were searched for articles that compared discontinuous neck dissection with in-continuity neck dissection in SCC of the tongue and floor of the mouth until March 1, 2017.

A comparison of mandible preservation method and mandibulotomy approach in oral and oropharyngeal cancer: A meta-analysis.

Objective: This study aims to compare the prognoses outcomes of mandibular preservation method (MPM) and the mandibulotomy approach (MLA) in oral and oropharyngeal cancer (OOPC) patients.

Method: We searched PubMed, Web of Science, EMBASE, Chinese BioMedical Literature Database (CBM), Cochrane Library, and clinicaltrials.gov up to September 2016 to identify the studies that compared the prognoses of the MPM versus the MLA in OOPC patients.

Total and near-total lower lip reconstruction: 20 years experience.

Background: Reconstruction of total and near-total lower lip defects presents a formidable challenge for the reconstructive plastic surgeon. Many methods have been described, and each has its own advantages and disadvantages. The aim of this article is to discuss the selection of techniques and report our experience of total or near-total lower lip reconstruction.

Modified incision design for submental flap: an excellent design method for the reconstruction of a defect after head and neck tumor resection.

Background: The usage of submental flap is a good method for head and neck reconstruction, but it has some risk also, such as anatomical variations and surgical errors. In this article, we present a modified incision design for the submental flap.

Methods: We designed a modified submental flap incision method based on the overlap of the incision outline of the submental flap, platysma myocutaneous flap and infrahyoid myocutaneous flap.

Yu's flap for lower lip and reverse Yu's flap for upper lip reconstruction: 20 years experience.

Reconstruction of defects of the lip caused by cancer with its requirements of a complicated anatomical structure, important physiological function, and acceptable cosmetic result, is a challenge for oral and maxillofacial and plastic surgeons. A method that combines rotation and advancement flaps was described by Yu in 1989 for the reconstruction of defects of the lower lip. In our department between January 1992 and December 2012, 8 patients had reverse Yu flaps for the reconstruction of upper lip defects and 56 patients had classic Yu flaps for lower lip defects.

Vertical platysma myocutaneous flap that sacrifices the facial artery and vein.

Background: Platysma myocutaneous flap (PMF) is a generally used technique for defect reconstruction after an oral cancer resection. The aim of the study is to present our experience using vertical PMF that sacrificed the facial artery and vein for intraoral reconstruction.

Methods: A retrospective review of the medical records of 54 patients who underwent vertical PMF that sacrificed the facial artery and vein for intraoral reconstruction was performed.

The versatile application of cervicofacial and cervicothoracic rotation flaps in head and neck surgery.

Background: The large defects resulting from head and neck tumour surgeries present a reconstructive challenge to surgeons. Although numerous methods can be used, they all have their own limitations. In this paper, we present our experience with cervicofacial and cervicothoracic rotation flaps to help expand the awareness and application of this useful system of flaps.

Superficial cervical artery island flap for large soft-tissue reconstruction of occipital and parotid region after tumor resection.

The application of microvascular free flaps is the most widespread method currently used for the reconstruction of extensive defects after resection of head and neck tumor. But not all patients are suitable for a free-flap reconstruction. The pectoralis major flap and trapezius musculocutaneous flap are the most used pedicled flap in large head and neck reconstruction.

[Protecting action of acupuncture serum on calcium over-loaded neurons of the hippocampus in rats of ischemia-reperfusion].

Objective: To investigate the effect of acupuncture serum on Ca2+ content in the cultured nervous cells of hippocampus after ischemia-reperfusion, so as to probe into humoral factors in acupuncture treatment.

Methods: The neurons of the hippocampus from the new born rats were cultured for 9-11 days. Fluorescein-molecular probe Fluo-3 AM was used for staining of intracellular Ca2+.

[Expression of telomerase genes hTRTmRNA in oral squamous cell carcinomas].

Purpose: To investigate the expression of telomerase genes in oral squamous cell carcinomas(OSCC).

Methods: Telomerase genes hTRTmRNA in 65 cases of OSCC, 25 cases of epidermal cells with abnormal hyperplasia and 20 cases of normal oral mucosa were detected by in situ hybridization. The digoxin-labelled probe was targeted to reverse transcription domain.

[Acupuncture-serum decreases Ca2+ content in cultured rat myocardial cells].

Objective: To explore whether humoral factors play a role in the mechanisms of acupuncture.

Methods: Primary culture of myocardial cells of neonatal rats were carried out. Five days later, they were labeled by fluorescent molecular probe Fluo-3AM.

[Preliminary study on effect of acupuncture serum on Ca2+ content in cultured neurons of cerebral cortex].

Objective: To observe effect of serum of the rat after acupuncture on Ca2+ content of cultured nervous cells in vitro for exploring the role of humoral factors in acupuncture.

Methods: Neurons of the cerebral cortex from the new born rats were taken and were cultured in a medium, 7 - 10 days later, fluorescein-molecular probe Fluo-3AM was used for staining of intracellular Ca2+. The intracellular Ca2+ levels in the nervous cells cultured with the serum of the normal rats or the rats given acupuncture at "Baihui" (GV 20), "Zusanli" (ST 36), "Quchi" (LI 11) and "Sanyinjiao" (SP 6) for 2 weeks were determined by using a laser confocal microscope.

[Effect of acupuncture serum on intracellular Ca2+ concentration in cultured neurons].

Objective: To study the humoral factor of acupuncture in improving functional activities of the organism.

Methods: Neurons of the cerebral cortex from the new born rats were taken to be cultured in a strictly controlled medium. Seven to ten days later, fluorescein-molecular probe Fluo-3AM was used for staining intracellular Ca(2+).

[Gene expression differences between high and low metastatic cells of adenoid cystic carcinoma].

Objective: To investigate the complex differences between high metastatic and low metastatic cells of the Adenoid cystic Carcinoma.

Methods: Gene expression patterns were examined in high metastatic cell ACC-M strain and low metastatic ACC-2 strain with the method SSH (suppression subtractive hybridization).

Results: although extensive similarity was noted between the expression profiles, twelve genes were highly expressed of, in low metastatic cell ACC-2 tester, compared with driver, high metastatic cell ACC-M.
