Objective To observe the outcome of free TAAP flap in the reconstruction of defect after oral tumor radical resection.Methods From June,2010 to April,2015,12 patients with oral tumor underwent radical resection,including 4 cases of gingival carcinoma,3 cases of tongue carcinoma and 5 case of buccal cancer.The cause ranged from 2 to 12 months.The radical resection left defects with size ranged from 4.5 cm×3.5 cm to 6.0 cm× 4.5 cm which were reconstructed by free TAAP flaps with size ranged from 7.0 cm×4.0 cm to 12.0 cm×8.0 cm.The length of TAAP flap was (6.5±0.6) cm.The width of flap was (4.3±0.5) cm.And the thickness of flap was (1.1±0.3)cm.The length of pedicle was(8.4±0.2) cm.All the arteries of TAAP were anastomosed with superior thyroid arteries,while the venae comitans were anastomosed with superior thyroid venae or internal jugular venae.Results The perforators existed consistently.All 12 flaps survived uneventfully.The donor sites were closed directly in all cases.All patients were followed up for 14-38 months with satisfied esthetic and functional results in reconstructed tongue.No local recurrence happened.The shoulder function was not affected.Conclusion The TAAP flap has consistent blood supply,good color match and texture,while leaving minimal morbidity at donor site,is an ideal choice for buccal tumor reconstruction.

Objective: To investigate the application of free medial thigh chimeric myocutaneous perforator flap in the reconstruction of tongue defect after radical resection of tongue carcinoma. Methods: From June 2013 to November 2015, 17 cases with tongue carcinoma underwent radical resection and tongue and mouth floor defects after surgery were reconstructed with medial thigh chimeric myocutaneous perforator flaps at the same stage. These 17 cases included tongue carcinoma on lingual margin (n=9), ventral tongue (n=7) and mouth floor (n=1). Appearance and functional results were evaluated with follow-up. Results: Medial thigh chimeric myocutaneous perforator flap was (9.0±0.3) cm in length, (4.5±0.3) cm in width , and (1.8±0.4) cm in thickness. The length of pedicle was (7.4±0.6) cm. All of the 17 flaps survived uneventfully, and the donor sites were closed directly in all cases. All patients were followed up for 10-28 months with satisfied esthetic and functional results in reconstructed tongue. Aside from linear scar in the donor sites, the functions of thighs were not affected. No local recurrence occurred. Conclusion The free medial thigh chimeric myocutaneous perforator flap is an ideal choice to reconstruct the tongue and mouth floor defect after radical resection of tongue carcinoma.

Objective The aim of this study is to explore the hypoglycemic effect of active components of Anoectochilus roxburghii on zebrafish models. Methods Anoectochilus roxburghii components were extracted and separated into three groups: the alcohol extraction group, macromolecular polysaccharide group (≥ 5 ×103) and small molecular polysaccharide group (＜5×103). Zebrafish embryos were exposed to 2% glucose solution (2% Glu) at 24 h to imitate acute hyperglycemia phenotype, and then treated with the three Anoectochilus roxburghii components. Based on this high-glucose model, the zebrafish embryos at 72 h were collected to detect the whole tissue glucose value. Furthermore, semi-quantitative PCR and whole mount in situ hybridization were performed to detect the expression of mRNA levels of glycometabolism-related genes. Results An acute diabetic zebrafish model was induced by high glucose stress. In this model, some key factors during glycometabolism such as insulin, pck-1 and pdx-1 were significantly affected, while the alcohol extracts of Anoectochilus roxburghii obviously reversed these abnormalities induced by high glucose stress, even to normal levels. Conclusions The alcohol extracts of Anoectochilus roxburghii has obvious hypoglycemic effect on diabetic zebrafish model. Our result suggest that Anoectochilus roxburghii has a potential application in the hypoglycemic drug screening.

Objective To review outcome and experience in application of various forms of transverse rectus abdominis musculocutaneous flap in breast reconstruction and chest wall radiation ulcer repairment.Methods From January 2008 to February 2016,61 cases (included 58 female patients and 3 male patients) were admitted,the age ranged from 39 to 57 years old.Among these cases,37 cases received mastectomy and one-staged breast reconstructive operation and multiple chemotherapy preoperatively.The other 24 patients suffered from chest wall radiation ulcer,all occurred after mastectomy and radiotherapy,the course ranged from 12 to 56 months,all received long-time conservative therapy but the patient's condition worsened.Of those patients 8 cases suffered radioactive bone injury,involved clavicle,rib and sterum;3 cases suffered pleura injury;2 cases suffered lung injury;2 cases suffered brachial plexus injury and upper extremity lymphedema,resulted in upper extremity dysfunction.The patients were treated with pure pedicled transverse rectus abdominis musculocutaneous flap (TRAM) musculocutaneous flap in 31 cases,frec TRAM musculocutaneous flap in 3 cases,pedicled TRAM musculocutaneous flap plus superficial inferior epigastric vein anastomosis in 13 cases,and pedicled TRAM musculocutaneous flap combined with contralateral free deep inferior epigastric perforator (DIEP) flap in 14 cases.Results The area of flap for chest wall reconstruction ranged from 22 cm × 10 cm to 38 cm× 15 cm,the size of flap for breast reconstruction ranged from 16 cm × 10 cm to 22 cm× 13 cm.The donor site was closed directly in all cases.Distal part necrosis and fat liquefaction were noted in 3 cases used pure pedicled TRAM musculocutaneous flap,in 1 case the defect was closed directly after radical debridement,in other 2 cases free anterolateral thigh flap was applied after debridement.All other 58 flaps survived uneventfully.All patients were followed up for 12 -108 months with satisfied esthetic and functional results in reconstructed chest wall and breast.No local recurrence or ulcer happened.Only linear scar left in the donor sites,no hernia occurred.Conclusions Transverse rectus abdominis musculocutaneous flap is one of the first choice for breast reconstruction and chest wall radioactive ulcer.To ensure the operation success,it is efficient to apply different forms of transverse rectus abdominis musculocutaneous flap according to the flap size and blood supply.

OBJECTIVETo evaluate the effect of basal serum luteinizing hormone (LH) and luteinizing hormone/follicle-stimulating hormone (LH/FSH) ratio on the clinical outcomes of in vitro fertilization-embryo transfer (IVF-ET) in patients with polycystic ovary syndrome (PCOS).

METHODSA retrospective analysis was performed of 134 IVF cycles in patients with PCOS. The cycles were classified into 2 groups according to serum levels of LH and also into 2 groups according to LH/FSH ratio, namely group A1 (LH≤10 IU/L), group A2 (LH>10 IU/L), group B1 (LH/FSH ratio<2), and group B2 (LH/FSH ratio≥2). The clinical characteristics, embryological data and pregnancy outcomes were compared between the groups.

RESULTSPatients in group A2 showed significantly higher FSH, T level, and LH/FSH ratio with a greater number of oocytes retrieved than those in group A1, but the time for down-regulation, duration of stimulation, AFC, LH and LH/FSH on the first day of stimulation, embryological data and pregnancy outcomes did not differ significantly between the two groups. Compared with group B1, group B2 showed higher basal LH, E2 level on the day of HCG, more oocytes retrieved and lower dose of gonadotropins used, but the time for down-regulation, duration of stimulation, LH and LH/FSH on the first day of stimulation and pregnancy outcomes were comparable between the two groups.

CONCLUSIONA high basal LH level or a high LH/FSH ratio does not produce obvious deleterious effect on the clinical outcomes of IVF-ET in women with PCOS who take oral contraceptives for pretreatment before long GnRH-agonist protocol.
