Abstract
Objective: To explore the clinical application and efficacy of lateral upper arm free flap (LUAFF) for one-stage repairing of soft tissue defect after oral cancer surgery. Methods: This article was a retrospective analysis of clinical data of 46 patients receiving treatment of one-stage repairing of soft tissue defect with LUAFF after oral cancer surgery in Hunan Cancer Hospital, from June 2019 to June 2021. Among these cases, 40 were males, and 6 were females. The patients' ages were from 23 to 64 years old. The clinical data of patients were reviewed and outcomes were evaluated. SPSS 23.0 software was used for statistical analysis. Results: In the LUAFF of 46 patients, flap area ranged from 5.0 cm×3.5 cm to 15.0 cm×7.0 cm; the mean pedicle length was 8.15±1.42 cm; the mean artery diameter was 1.20±0.41 mm (range, 1.5 to 2.5 mm); the mean diameter of the largest veins was 2.15±0.52 mm; and the median number of perforators was 2.6 (range, 1 to 4). All donor sites were closed primarily. Two cases had arterial anastomosis thrombosis, but their flaps were successfully saved with urgent re-anastomosis of the vessels. The overall flap survival rate was 93.5%(43/46), with flap necroses after operation in three cases. No patient received tracheotomy. The average hospital stay time of patients after operation was 9.4 days. The follow-up time was 6-24 months, elbow and wrist movements on the operative side were normal, and the upper limb muscle strength was not affected. Conclusions: LUAFF is a suitable choice for the repairs of small-moderate tissue defects in oral cancer surgery, with consistent perforators in the flap, simple harvest method, concealed donor-site scar, and high survival rate.

Abstract
Glutaredoxins (GRXs) are small oxidoreductases that can modify target protein activities through control of the redox (reduction/oxidation) state by reducing or glutathionylating disulfide bridges. Although CC-type GRXs are plant specific and play important roles in many processes, the mechanisms by which they modulate the activity of target proteins in vivo are unknown. In this study, we show that a maize CC-type GRX, MALE STERILE CONVERTED ANTHER1 (MSCA1), acts redundantly with two paralogues, ZmGRX2 and ZmGRX5, to modify the redox state and the activity of its putative target, the TGA transcription factor FASCIATED EAR4 (FEA4) that acts as a negative regulator of inflorescence meristem development. We used CRISPR-Cas9 to create a GRX triple knockout, resulting in severe suppression of meristem, ear and tassel growth and reduced plant height. We further show that GRXs regulate the redox state, DNA accessibility and transcriptional activities of FEA4, which acts downstream of MSCA1 and its paralogues to control inflorescence development. Our findings reveal the function of GRXs in meristem development, and also provide direct evidence for GRX-mediated redox modification of target proteins in plants.

Abstract
Objective: To explore the classification and reconstruction strategy of defects in lateral face region after operation of malignant tumors. Methods: Eighteen cases with the reconstruction of complicated defects after resection of tumors in the region of lateral face from January 2015 to January 2018 in Hunan Cancer Hospital were retrospectively reviewed. There were 14 males and 4 females, aged from 32 to 68 years. According to the presence or absence of bony scaffold, complicated defects were divided into two main categories: soft tissue perforating defects and soft tissue defects combined with bony scaffold defects. All soft tissue perforating defects in 5 cases were repaired with free anterolateral femoral flaps. Among 13 cases with soft tissue plus bony scaffold defects, 3 were repaired with free fibular flaps, 6 with free fibular flaps combined with free anterolateral femoral flaps, and 4 with chimeric deep circumflex iliac artery perforator flaps combined with anterolateral femoral flaps. Results: All flaps survived well. Two patients complicated with fistula in floor of mouth, but the wound healed after dressing change. Transoral feeding was resumed within 2 weeks after surgery in all patients. One year follow-up evaluation showed that 14 cases had symmetrical face and 10 cases had mouth opening more than 3 transverse fingers. After 36-50 months of follow-up, 6 patients died, with an overall 3-year survival rate of 66.7%. Conclusion: The classification of defects with or without bony stent loss is conducive to the overall repair design, the recovery of facial contour stent, the effective fill of dead space and the maintain of residual occlusal relationship. Good reconstruction results require a multi flap combination of osteocutaneous and soft tissue flaps.

Abstract
Five patients with primary malignancies in the pterygopalatine fossa (PPF) and infra temporal fossa (ITF) were enrolled in this retrospective study between January 2012 and January 2018. After malignancies proven by biopsy and evaluation with CT and MRI scan, all patients received modified maxillary swing (MMS) approach for extirpation of malignant tumors in the PPF and ITF under general anesthesia. En bloc resection with wide surgical margins was successfully performed in all cases. Negative margins were observed in 4 cases and positive margins were found in one patient with adenoid cystic carcinoma who received postoperative radiotherapy. The most common complication was facial numbness. During the follow-up period (range 12 to 57 months), one patient suffered from recurrence while others did not. The advantages of MMS include wide surgical field, full exposure and easy manipulation. The MMS approach is expected to become an standard method for monobloc resection of malignancies in the PPF and ITF.

Abstract
SUMMARY Although medical therapy is still the mainstay of treatment for Parkinson's disease, the development of surgical precision and decreased morbidity have made stereotatic lesioning and deep brain stimulation more popular. Neurosurgical ablations include pallidotomy, thalamotomy, and, more recently, subthalamotomy. Because of concern over the high risk of side-effects resulting from bilateral ablative procedure, alternative approaches have been explored.With improved deep brain stimulation (DBS) technology, DBS has been successfully applied in the internal globus pallidus, ventral intermediate nucleus and subthalamic nucleus for Parkinson's disease. In addition, recent surgical approaches including biological neurorestorative technologies - surgical therapies with transplantation, gene therapy, and growth factor are all being discussed in this review. Although a great deal of work remains to be done for researchers, advances in surgical therapies for the treatment of Parkinson's disease are moving forward at an unprecedented pace, and, not surprisingly, would give PD patients more choices and hope.
