With redox-sensitive fluorescene probes DCFH-DA and DHR123, the formation of cytosolic and intramitochondrial reactive oxygen species (ROS) inside immature rat cerebellar granule cells during the apoptosis induced by nitric oxide donor S-nitroso-N-acetyl-pennicillamine (SNAP) was monitored by laser confocal scanning microscopy. The cytosolic and intramitochondrial ROS increase significantly after 0.5 mmol/L SNAP treatment for 1 h. Pre-treatment with the nitric oxide scavenger hemoglobin can effectively inhibit the formation of cytosolic and intrarnitochondrial ROS and protect neurons from apoptosis. Adding glutathione can also protect neurons from apoptosis, and the cytotoxity of nitric oxide increases significantly while the synthesis of glutathione is inhibited. The results indicated that ROS might be involved in NO-induced apoptosis in neural cells and glutathione might be the endogenesis antioxidant to protect neurons from oxidative injury.

Objective To observe the effect of atropine in the treatment of bromiderosis with anhydrous alcohol injection. Methods Patients were randomly divided into two groups (A and B): the patients in Group A was injected with both anhydrous alcohol and atropine, and that in Group B was only injected with anhydrous alcohol. The effect of the operation was evaluated at 1, 3 and 6 months after the treatment. Results From August 2004 to January 2008, 72 patients were involved in this study. 37 cases were included in Group A, and 35 patients were included in Group B. The effective rate in the Group A was 83.78 %, and that in the Group B was 82.86 %. There was no statistical difference between these two groups. Conclusion Atropine has no effect on the treatment of axillary bromidrosis with anhydrous alcohol injection and it is, therefore, not necessarily included in the treatment.

Objective: To explore the clinical application of vascular augmentation of an extra-long latissimus dorsi flap through an intercostal artery in limb wound repair. Methods: Between January 2016 and December 2017, 5 patients with limb wounds were treated with the extra-long latissimus dorsi flaps. The vascular augmentation of the extra-long latissimus dorsi flap through the intercostal artery was applied during the operation. There were 4 males and 1 female, with an average age of 45.8 years (range, 43-59 years). The time from post-traumatic admission to flap repair was 7-25 days (mean, 12.3 days). The causes of injury included machine injury in 2 cases, traffic accident in 2 cases, and roller crush injury in 1 case. The wounds were located at the anterior of upper limb in 3 cases, the posterior of upper limb in 1 case, and the posterior of leg in 1 case. The size of wounds ranged from 26 cm×8 cm to 38 cm×10 cm. The size of the latissimus dorsi flap ranged from 36 cm×6 cm to 43 cm×7 cm. The size of the muscle flap ranged from 36 cm×10 cm to 43 cm×15 cm. The donor sites were closed directly. Results: The distal flap necrosis occurred in 1 case and healed after symptomatically treatment. The other flaps survived completely. The wounds and incisions at donor sites healed by first intention. All patients were followed up 8-18 months with an average of 14.9 months. At last follow-up, the flaps had satisfactory appearances, soft textures, and function of sweating. Conclusion: Application of vascular augmentation of the extra-long latissimus dorsi flap through the intercostal artery in repair of limb wound can reduce the incidence of distal flap necrosis and achieve satisfactory effectiveness.

Objective To explore the clinical application of antcrolateral thigh flap transplantation in repairing wound around the knee with descending genicular artery as the recipient vessel,when anterior or posterior tibial vessel could not be utilized.Methods From January,2015 to May,2017,free anterolateral thigh flaps obtained from anastomosis of descending genicular artery and great saphenous vein were transplanted to repair the skin soft tissue defect around the knee combined with tendon and bone exposure in 7 patients,after preoperative color Doppler sonography ultrasound (CDU) for precise positioning.There were 4 males and 3 females,with the flap area ranging from 18.0 cm×8.0 cm-38.0 cm×8.0 cm.All of the donor sites were sutured directly.Postoperative followedup was done termly.Results All the patients were followed-up for 6 to 14 months,with an average of 8.9 months.Typically,2 cases had large defect areas,with distal flap necrosis of 6.0 cm and 4.0 cm,respectively,which were resected and achieved secondary skin graft healing on the residual surface.Additionally,4 cases had completely survived flaps and achieved secondary skin graft healing on the residual surface.The remaining 1 case had completely survived flap,but the distal flap near the anteromedial tibia developed bone exposure as a result of the complicated osteomyelitis.As a result,the patient received gastrocnemius myocutaneous flap to repair the wound.Conclusion Anterolateral thigh flap transplantation in repairing skin soft tissue defect wound around the knee,with descending genicular artery as the recipient vessel,can achieve satisfactory clinical efficacy,which can serve as one choice for flap repair in wound around the knee.

Objective The combined application of X-ray photography and various ultrasound examination techniques to evaluate the clinical outcome of developmental dysplasia of the hip (DDH) in early diagnosis and treatment. Methods A retrospective analysis of the data of 296 hips in 148 infants with DDH risk factors from September 2017 to September 2018 was classified by Graf method. Harcke method was applied to evaluate the stabilities of the hips. Ottobock harnesses was used for treatment depending on the classification. Human position spica cast would be given if no efficacy was seen and Novick method was applied to observe the location of femoral head and acetabulum. X-rays were given to the infants underwent treatments when they were above 1 year old and the developments of the hips were evaluated. Results There were 207 type Ⅰ hips, 76 type Ⅱ hips, 3 type D hips, 6 type Ⅲ hips and 4 type Ⅳ hips as Graf classification at first examination. 248 hips were stable, 27 hips were relaxed, 5 hips were dislocated when compressed, 13 hips were reducible and 3 hips were irreducible as Harcke classification. 81 hips were treated in all. All the hips turned to be in normal range at age of 1 year. Conclusion The combination of X-ray scan and three ultrasound tools are effective to comprehensively assess the hip joint and precisely diagnose DDH, which may benefit more infants.

Objective To assess the clinical efficacy of perforators positioning technique in anterolateral thigh perforator sub lobe flap transplantation for reconstructing soft tissue defects of forearm or hand.Methods A retrospective case series study was performed to analyze 24 patients with forearm and hand soft tissue defects admitted from January 2013 to August 2017.There were 18 males and six females,aged 31-68 years (mean,52.3 years).The wound defect areas ranged from 11 cm × 10 cm to 18 cm× 14 cm.The anterolateral thigh sub lobe perforator flaps were used for repair.CT angiography (CTA) combined with color Doppler ultrasound (CDS) was used to determine the perforator position before operation.After the appropriate thigh side was selected according to the perforator position and the wound area,the lobed flaps were designed to ensure all the flaps for the stage I suture after the length was converted into width.All patients obtained stage Ⅱ repair,and the repair time was 5-29 days,with an average of 13 days.The accuracy of perforation positioning was observed during operation (the error was not more than 1 cm for accurate positioning).The flap survival and complications were recorded within 2 weeks after operation.Follow-up was performed using the seven indicators of flap function to evaluate the efficacy.Results The positioning accuracy rate was 99％.One case was seen necrosis about 2 cm at the proximal end of flap.Two cases had arterial crisis after flap operation and survived after active exploration.In two nonunion cases because of wound infection around the flap,one case was healed after dressing change,and another case was healed after debridement.The donor site of the flap obtained stage Ⅰ direct suture,and one case was seen obvious scar hyperplasia at the donor site.Flaps were made thinner in two patients with hand defects at the later stage.All 24 patients were followed up for 7-33 months,with an average of 18.3 months.According to the seven indexes of the flap function,the results were excellent in seven cases,good in 13,fair in three,and poor in onee,with an excellent and good rate of 83％.The flaps appeared soft with good color at the last follow-up.Conclusions In the treatment of soft tissue defects of forearm or hand using anterolateral thigh flap,conversion from length to width and direct suture of donor site can cover the wound well and reduce complications.Perforators positioning technique can facilitate precise preoperative planning and intraoperative accurate cutting.
