Objective To evaluate the clinical effect of nanofat on superficial rhytides of face and neck and dark lower eyelids.Methods From September 2014 to January 2017,a total of 86 cases were collected in our hospital for voluntary nanofat transplantation on superficial rhytides and dark lower eyelids.This was a retrospective study,which included 18 cases of eye wrinkles,14 cases of forehead wrinkles,neck wrinkles in 14 cases,and 22 cases of dark lower eyelids.First of all,we harvested mircofat through liposuction,and then transformed mircofat to nanofat.At last,nanofat was grafted into intradermal layer of the skin with sharp needles.We took the standard photographs of the patients.After six months follow-up,doctors and patients evaluated the short term and long-term postoperative effect.Results No serious complications occurred in all patients.Postoperative evaluation of facial and neck superficial wrinkles showed that the satisfactory rate of doctors and patients after one month,was 85.9％and 84.3％,and after 6 months 87.5％ and 84.3％,respectively.Postoperative evaluation of dark lower eyelids showed that the satisfactory rate of doctors and patients after one month was 45.5％ and 36.4％,and after 6 months 81.8％ and 86.4％,respectively.Conclusions Nanofat can rectify the superficial rhytides of face and neck and dark lower eyelids in some patients.However,for some patients the effect is not satisfied.

Objective: To evaluate the application of the expanded free deltopectoral flap, pedicled with perforation of internal thoracic artery, in the repairment of middle to large facial skin and soft tissue defect. Methods: From June 2015 to December 2017, 11cases diagnosed with facial lesions were included in this study. The tissue defect of 10 cases were caused by burn, and 1 case by superficial tumor. In the first stage, the tissue expander was implanted into the internal thoracic artery supplying area. After the expander was fully expanded, the second surgery, i. e. the resection of facial lesion, was performed. The defect areas of patients, with the range of 9 cm×7 cm to 17 cm×10 cm, were repaired by expanded free deltopectoral flaps. Results: All flaps were survived, with no vascular crisis occurred. The size of flaps ranged from 10.0 cm×9.0 cm to 18.0 cm×11.5 cm. All the patients were satisfied with the outcomes, after 6 to 24 months follow-up. The color and texture of flaps was close to normal. The scars were acceptable. Conclusions The expanded free deltopectoral flap, pedicled with the perforator of internal thoracic artery, is a promising way to repair middle to large facial skin and soft tissue defect.

OBJECTIVE: To treat superficial hemangioma in children according to the local blood flow. METHODS: A total of 98 children with superficial hemangiomas admitted to our hospital from January 2005 to June 2009, and their clinical data were analyzed. RESULTS: According to the local blood flow velocity, 98 children were treated with injections or injection plus surgical treatment, respectively. Ninety-four children (95.9%) were cured. CONCLUSION Injection therapy is effective for children with superficial hemangioma, but we should arrange individualized treatment according to the local blood flow in children.

Objective: To compare the outcome of radiofrequency catheter ablation under local anesthesia/sedation (S) or general anesthesia(GA) in atrial fibrillation patients. Methods: Data of 498 patients with atrial fibrillation undergoing radiofrequency catheter ablation in our departmentfrom January 2014 to December 2015 were retrospectively analyzed. Two hundred and twenty patients assigned to the GA group, the other 278 patients to the S group. Patients were followed clinically every 3 months within one year after procedure. Immediate electrocardiogram was performed in patients with palpitation or choking sensation in chest. The end point of the study was recurrence of any atrial tachyarrhythmia lasting >30 seconds in device interrogation, 24-hour Holter monitoring or 12-lead electrocardiogram after a single procedure. After the ablation procedure, a blanking period of 3 months was allowed according to the guidelines. Procedure time, radiofrequency time, fluoroscopy time, the detection of paroxysmal supraventricular tachycardia, the success rate and the complications were compared between the two groups. Results: There was no difference in the baseline characteristics between the two groups, such as age, gender, BMI, complications, LVEF, LAD (all P>0.05). The duration of procedure ((117.8±51.7)minutes vs.(115.4±36.9)minutes, P=0.79), duration of fluoroscopy((12.5±11.2)minutes vs. (10.4±10.2)minutes, P=0.35), duration of radiofrequency((40.1±12.9)minutes vs. (48.6±44.3)minutes, P=0.48) were similar between the two groups (P>0.05). Compared with S group, discovery of the frequency of atrioventricular node reentrant tachycardia (AVNRT) was significantly lower in GA group (0 vs. 3.6%(10/278), P<0.01), but the difference disappeared with repeat electrophysiological examination when patients become conscious from GA(3.2%(7/220) vs. 3.6%(10/278), P=0.311). The difference of atrioventricular reentrant tachycardia (AVRT) was similar between the two groups(0.9%(2/220) vs. 0.7%(2/278), P=0.841). Compared with S group, reflection of vagus nerve was less in GA group (1.4%(3/220) vs. 8.6%(24/278), P=0.026). After following up of (356±92) days, freedom from atrial fibrillation/atrial flutter/atrial tachyarrhythmia was similar between the two groups(77.9%(162/208) vs. 79.9%(215/269), P=0.818). Conclusion General anesthesia is a promising method to atrial fibrillation ablation, in view of stable patient status and safety for the procedure. There is no difference in complications, recurrence of arrhythmia between the two groups, but detection rate of AVNRT is lower in GA group.

Objective: To analyze the recent postoperative and long-term postoperative complications of open-splenectomy and disconnection in patients with portal hypertension. Methods: There were 1 118 cases with portal hypertension who underwent open splenectomy and azygoportal disconnection from April 2010 to September 2015 at Department of Surgery, People′s Liberation Army 302 Hospital. Retrospective case investigation and telephone follow-up were conducted in October 2016. All patients had history of upper gastrointestinal bleeding before operation. Short-term complications after surgery were recorded including secondary laparotomy of postoperative abdominal hemostasis, severe infection, intake disorders, liver insufficiency, postoperative portal vein thrombosis and perioperative mortality. Long-term data including postoperative upper gastrointestinal rebleeding, postoperative survival rate and incidence of postoperative malignancy were recorded, too. GraphPad Prism 5 software for data survival analysis and charting. Results: Postoperative short-term complications in 1 118 patients included secondary laparotomy of postoperative abdominal hemostasis(1.8%, 21/1 118), severe infection(2.9%, 32/1 118), intake disorders(1.0%, 11/1 118), liver dysfunction (1.6%, 18/1 118), postoperative portal vein thrombosis(47.1%, 526/1 118)and perioperative mortality(0.5%, 5/1 118). After phone call following-up, 942 patients′ long-term data were completed including 1, 3, 5 years postoperative upper gastrointestinal rebleeding rate(4.4%, 12.1%, 17.2%), 1, 3, 5-year postoperative survival rate(97.0%, 93.5%, 90.3%); the incidence of postoperative malignant tumors in 1, 3 and 5 years were 1.7%, 4.4% and 6.2%. Conclusions Reasonable choosing of surgical indications and timing, proper performing the surgery process, effective conducting perioperative management of portal hypertension are directly related to the patient′s short-term prognosis after portal hypertension. Surgical intervention can reduce the rates of patients with upper gastrointestinal rebleeding, improve survival, and do not increase the incidence of malignant tumors.
