Objective To evaluate the clinical efficacy of Achillon,a novel guide for Achilles tendon suture produced by Newdeal Ltd in France,in the mini-invasive surgical treatment of acute Achilles tendon rupture. Methods Between December 2010 and March 2011,7 patients(7 feet) with acute Achilles tendon rupture were treated in our department.They were 5 males (5 feet) and 2 females (2 feet),with an average age of 34.2 years (range,21 to 53 years).The interval between injury and operation ranged from 1 to 11 days(3.8 days on average).A longitudinal incision approximately 2.0-3.5 cm in length was made around the ruptured Achilles tendon for minimally invasive repair after insertion of the Achillon.Postoperative rehabilitation was carried out. Results All the wounds healed at the first stage.All patients were followed up for 5 to 11 months, with an average of 7.2 months. All patients regained normal weight-bearing walking 3 months after operation without any re-rupture. According to the ankle-hindfoot scoring system of American Orthopaedic Foot and Ankle Society (AOFAS),they scored 93.2 points.By the visual analogue scale(VAS),they scored 1.2 points at the operation site. Conclusion The surgical treatment of acute Achilles tendon rupture with Achillon has advantages of mini-invasion,a low rate of incision problems and quick function recovery.

Objective:To explore the clinical characteristics and risk factors of severe and critical influenza in children.Methods:The clinical data of 214 inpatient children with severe and critical influenza hospitalized in the Second Affiliated Hospital & Yuying Children′s Hospital of Wenzhou Medical University from January 1, 2016 to December 31, 2019 were retrospectively collected. The clinical characteristics including age, gender, symptoms, signs, underlying diseases, C-reactive protein (CRP), treatment and outcome of children with severe and critical influenza were compared. Chi-Square test was used for statistical analysis. A binary logistic regression model was constructed to analyze the risk factors for critically ill influenza.Results:Of the 214 children, 153 were male (71.5%), 177(82.7%) were under 5 years old. There were 52 children with underlying diseases. Fever occurred in 207 cases. Among the 54 cases that had convulsion during the course of the disease, three developed acute necrotizing encephalopathy. The influenza subtype was mainly type A, accounting for 190(88.79%). A total of 42(19.6%) children were critically ill. The incidence of critical influenza in children with underlying diseases (61.9%, 26/42) was higher than that in severe influenza children (15.1%, 26/172), and the difference was statistically significant ( χ2=40.175, P<0.01). The incidence of critical influenza in children with CRP≥40 mg/L was higher than that of severe influenza in children with CRP ≥40 mg/L (33.3%(14/42) vs 9.3%(16/172)), and the difference was statistically significant ( χ2=16.173, P<0.01). Multivariate logistic regression showed that underlying diseases (odds ratio ( OR)=8.794, 95% confidence interval ( CI) 3.845-20.111) and CRP ≥40 mg/L ( OR=5.050, 95% CI 1.966-12.970) were risk factors for critical influenza. All severe cases were improved and discharged.Among the 42 critically ill children, seven children died. Conclusions:Among the severe and critical influenza in children, the majority of children are under five years old.Underlying diseases and CRP ≥40 mg/L are risk factors for critical influenza.

Background and purpose:Gestational trophoblastic neoplasm (GTN) is a spectrum of disease arising from trophoblastic cells, and the majority of patients with GTN have favorable outcome because of the sensi-tivity to chemotherapy. While the cure rate for high-risk patients is still 70% to 80% as a result of drug resistance and disease recurrence. This study aimed to evaluate the clinical characteristics and outcome of patients with high-risk GTN.Methods:The clinical records of patients with high-risk GTN treated in Obstetrics and Gynecology Hospital of Fudan University from Jan. 2003 to Jan. 2013 were analyzed and reviewed retrospectively from the aspect of different treatment.Results:Fifty-one patients with high-risk GTN were admitted to this hospital. Among 51 high-risk GTN patients, 46 patients were evaluated retrospectively and 5 patients were excluded for incomplete treatments. Of the 46 patients with high-risk GTN, 27 patients were treated by chemotherapy alone, 19 patients received chemotherapy and adjuvant surgical therapy. Forty-four patients received EMA-CO (VP-16+Act-D+MTX/VCR+CTX) as a ifrst-line chemotherapy, 81.82% (36/44) had complete remission and 8 patients developed resistance to EMA-CO. EMA-EP (VP-16+Act-D+MTX/VP-16+cisplatin) was used as second-line chemotherapy for the 8 patients resistant to EMA-CO, 6 patients (2 underwent adjuvant surgical therapy) achieved remission and 2 patients died as a result of drug-resistance and disease progression. For the remaining 2 patients, one was treated by 5-FU+KSM and pulmonary resection, and the other was treated by MTX for misdiagnosis as ectopic pregnancy and then converted to EMA-CO for the pathological diagnosis of choriocarcinoma after surgery. Both of them achieved complete remission. Ultimately, 95.65% (44/46)patients achieved complete remission. Among the 19 patients who underwent adjuvant surgical therapy, 94.70% (18/19) patients achieved complete remission after chemotherapy and adjuvant surgery, and the remaining one patient died of disease progression.Conclusion:Standard combination chemotherapy is crucial in the treatment of high-risk GTN. The role of adjuvant surgery in the management of high-risk GTN should not be underestimated.

Objective To retrospectively analyze whether the kyphosis exists after removal of the internal fixators for thoracolumabar vertebrae fractures. Methods A total of 18 patients (35-68 years old) with thoracolumabar vertebrae fractures (T11-L2 ) were fixed with short segment pedical screw. The fixators were removed one year postoperatively to observe the changes of the Cobb' s angle and trauma vertebra'height. Results All the patients were followed up for 6-24 months ( average 18.7 months),which showed no intraoperative or postoperative complication, breakage or loosening of the screws. Compared to the Cobb angle and the vertebra height before removal of the internal fixators, the average loss of the Cobb angle was 0.7° and that of the vertebra height was 0.8 mm six months after removal of the fixators, 1.9° and 1.1 mm respectively one year after removal of the fixators, and 2.4° and 1.3 mm respectively two years after removal of the fixators in 16 patients without osteoporosis (P >0. 05). Among two patients with osteoporosis, the average loss of the Cobb angle and the vertebra height was 6° and 8°respectively and 3 mm and 5 mm respectively six months after removal of the fixators; 13° and 17° respectively and 5 mm and 7 mm respectively one year after removal of the fixators; 15° and 19° respectively and 6 mm and 7.5 mm two years after removal of the fixators. Conclusions After the internal fixation for thoracolumbar vertebrae burst fractures, kyphosis develops mildly, with insignificant change of the vertebral height. While the kyphosis becomes worse after removal of the fixators for thoracolumbar vertebrae burst fractures in patients with osteoporosis.
