Objective To explore the clinical efficacy of NEOVEIL in postoperative pulmonary air leakage of pulmonary bullae resection by video-assisted thoracic surgery. Methods We retrospectively analyzed clinical data of 37 cases received NEOVEIL combined with ATB45 in video-assisted thoracic surgery (the NEOVEIL group), and clinical data of 40 cases by ATB45 alone(the control group) . We compared postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary infection in the two groups. Results There was no postoperative mechanical ventilation,hemothorax and death. In the NEOVEIL group, the postoperative hospitalization time was 5 to 9 days, the postoperative keeping time of pleural cavity tubes 2 to 4 days, the postoperative pulmonary leakage time 0 to 2 days with 4 patients un-leakage, and 1 patients with pulmonary infection; whereas the postoperative hospitalization time was 6 to 10 days,the postoperative keeping time of pleural cavity tubes 3 to 6 days,the postoperative pulmonary leakage time 2 to 5 days and 8 patients with pulmonary infection in the control group. There was statistical significance in the postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary inflammation in two groups(P ＜ 0. 05). The incidence of pulmonary inflammation of the NEOVEIL group (2. 7%) was significantly lower than that of the control group(20. 0%)(x2 = 4. 02, P ＜ 0. 05). Conclusion The operative effectiveness of the NEOVEIL group is better than that of the control group. The NEOVEIL can prevent the postoperative pulmonary leakage.

Objective:To evaluate the precise guidance of intraoperative ultrasound for closed reduction and fixation with intramedullary titanium elastic nail (TEN) in the treatment of clavicle fractures.Methods:The data of 40 patients with fresh clavicle fracture were retrospectively analyzed who had undergone closed reduction and TEN fixation under precise guidance of intraoperative ultrasound at Department of Emergency Trauma, Shandong Wendeng Osteopathic Hospital from January 2017 to March 2019. They were 25 males and 15 females, aged from 25 to 68 years (average, 52.1 years), with 27 cases on the left side and 13 on the right. Reduction and fixation of the fracture was monitored during operation to avoid iatrogenic injuries to the subclavian brachial plexus nerve, subclavian artery and vein and thoracic cavity. The Neer scoring was used at the last follow-up to assess shoulder joint function and complications were recorded.Results:Closed reduction and TEN fixation was completed uneventfully in all the 40 patients under precise guidance of intraoperative ultrasound. The operation time ranged from 20 to 56 min, averaging 36 min; the blood loss from 10 to 35 mL, averaging 22 mL. No injury occurred to the subclavian brachial plexus, subclavian artery or vein, or thoracic cavity. The 40 patients were followed up for 4 to 6 months (average, 4.8 months). All fractures achieved bony union, with no displacement or breakage of internal fixation, or fracture malunion. At the last follow-up, the shoulder joint function was good, with Neer scores ranging from 85 to 95 points (average, 93.1 points).Conclusion:The precise guidance of intraoperative ultrasound improves surgical accuracy and safety, making the closed reduction and TEN fixation a safe and minimally invasive treatment for clavicle fractures.

Objective To explore the experience in the diagnosis and treatment of elastofibroma dorsi.Methods Clinical data of 19 cases of pathologically confirmed elastofibroma from October 2001 to October 2011 were reviewed.The clinical features,the specific radiological characteristics,the typical pathological alterations and the short-term and long-term effects were analyzed.Results All the lesions were located within the muscles in the subscapular region.There were 3 cases with bilateral lesions and 16 cases with unilateral lesions.Seven patients complained of local pain and feeling of foreign body when activated the upper limb,while 12 were asymptomatic.Except for the early 6 cases,accurate diagnosis was made in all the other 13 cases before the histological exams solely based on the physical examination and imaging findings.Marginal excision was done for all the cases:the diameters of the masses were between 3 centimeters to 10 centimeters.Fluid accumulation complications was found in 1 case and resolved by repeated paracentesis;errhysis complication,was found in 1 case and resolved by compression,applying hemostatics and blood transfusion.No recurrence was found during the follow-up period(6 months to 48 months).Conclusion Elastofibroma dorsi is usually found in the subscapular region in elderly women.The diagnosis can be made on the basis of unique imaging characteristics and physical examination before histological examine.Surgical marginal excision can achieve good short-term and long-term effects.

BACKGROUND:Some studies have shown that more copy number variations are present in early passage human induced pluripotent stem cells than later passage human human induced pluripotent stem cells, their parental somatic fibroblasts or human embryonic stem cells. OBJECTIVE:To investigate whether the reprogramming process itself compromises genomic stability and further explore the efficiency of induced pluripotent stem cellestablishment. METHODS:Using high-resolution Affymetrix CytoScan HD array, we compared copy number variations and loss of heterozygosity in early passage induced pluripotent stem cells with their fibroblast cellorigins from genetic epilepsy patients. RESULTS AND CONCLUSION:Compared with somatic fibroblasts from genetic epilepsy patient, there was no difference in the loss of heterozygosity between the two types of cells, but more copy number variations were present in early passage human induced pluripotent stem cells which were characterized as microduplication and involved oncogenic genes. Results demonstrate the dynamic nature of genomic abnormalities during reprogramming process and the necessity of frequent monitoring human induced pluripotent stem cells to assure their genomic stability and clinical safety.
