Risk factors of neurologic complications after surgical resection of carotid body tumor / 中华普通外科杂志

Objective:To investigate risk factors of nerve injury after carotid body tumor resection.Methods:From 1991 to 2016, the clinical data of patients with neurologic complications after resection of carotid body tumor was retrospectively analyzed. Logistic regression analysis was used to investigate the risk factors of nerve injury.Results:A total of 132 patients with 142 tumors underwent surgery. 45 patients (46 sides) suffered nerve injury, including 4 strokes and 44 nerve injuries. After active rehabilitation, 18 cases were left with permanent nerve injury, and the 4 patients with strokes regained self-care ability. By multivariate regression analysis, high-lying tumors ( OR=4.345, P=0.005), Shamblin Ⅲ tumor ( OR=4.382, P=0.047) increase the risks of postoperative nerve injury. Resection of high-lying tumors carried a higher risk of developing permanent nerve injury ( OR=7.290, P=0.001). Conclusions:Neurologic complication could be alleviated by rehabilitation. Intraoperative abrupt rupture of carotid artery is the leading cause of stroke. Shamblin Ⅲ and high-lying tumor are the predictors of postoperative nerve injury.

Association between admission diagnosis and immunotherapy outcome in patients with autoimmune epilepsy / 中南大学学报(医学版)

To evaluate the impact of admission diagnosis on seizure outcome in patients with autoimmune epilepsy (AE).
 Methods: We conducted a retrospective study on 40 AE patients at Department of Neurology, Xiangya Hospital, Central South University from Jan. 1st, 2017 to Nov. 21st, 2018. According to their admission diagnosis, these patients were further assigned into 2 groups: An AE diagnosed group and an AE undiagnosed group. Demographic data, clinical characteristics, cerebrospinal fluid (CSF), electroencephalogram, and brain imaging were compared between the 2 groups. Favorable seizure outcome was defined as >50% reduction of seizure frequency at the first follow-up. The impact of admission diagnosis on seizure outcome of AE patients was analyzed.
 Results: The ages of 40 AE patients were (33.23±16.41) years, comprising 19 males and 21 females. No significant difference was found between the AE diagnosed group and the AE undiagnosed group in gender, age, central nervous system-specific Ab profile, CSF, and brain imaging. Duration of symptom onset to Ab detection was significantly longer in the AE undiagnosed group than that in the AE diagnosed group (P<0.01). Duration of symptom onset to immunotherapy was also significantly longer in the AE undiagnosed group than that in the AE diagnosed group (P<0.001). There were more patients with favorable seizure outcome in the AE diagnosed group than the AE undiagnosed group (P<0.05).
 Conclusion: Admission diagnosis for patients with AE is associated with seizure outcome after immunotherapy. For adult-onset epilepsy or epilepsy with unknown etiology, the diagnosis of AE should be considered. Early diagnosis of AE and prompt initiation of immunosuppressive treatment are crucial to increase the likelihood of achieving favorable seizure outcome.

Symmetry analysis of a 3D printed model of distal radius / 中华创伤骨科杂志

Objective To investigate whether a 3D printed model of the contrlateral healthy distal radius, especially its articular accuracy, helps anatomical reduction and precise reconstruction of the fractured distal radius. Methods The CT data of bilateral radii were collected from 15 normal volunteers ( 11 males and 4 females with an average age of 22. 8 years ) between November and December 2016. After 3D reconstruction of the bilateral distal 1/3 radii, solid 3D models of left radius were mirrored and generated by 3D printing. The data of right radii ( reference group ) were compared with the data of the solid 3D models of left radius acquired through a 3D scanner ( test group ) using deviation analysis. Results The maximum volume difference between the 3D printed model and the contralateral radius was 6. 86％. The average volume of the reference group was 19, 165. 82 ± 3, 250. 50 mm3 and that of the test group 19, 310. 65 ± 3, 305. 15 mm3, showing no statistically significant difference between the 2 groups ( t= -0. 941, P=0. 363 ) . The maximum surface area difference was 3. 84％ between the 2 groups. The average surface area of the reference group was 5, 075. 80 ± 549. 34 mm2 and that of the test group 5, 139. 43 ± 572. 48 mm2, showing a signifi-cant difference ( t= -2. 451, P=0. 028 ) . The 3D deviation analysis showed a mean positive deviation of 0. 37 ± 0. 10 mm and a mean negative deviation of 0. 30 ± 0. 07 mm. The maximum mean square root was 0. 65. The 3D deviation was distributed mainly within 1 mm interval, with a distribution frequency of 96. 27％. Conclusions A 3D printed model prepared by high precision equipment is accurate enough to guide reconstruction of distal radius fractures in adults. In the treatment of complex fractures of the distal radius, a 3D printed model of the contralateral healthy distal radius can be used as a reference to achieve anatomical reduction and precise reconstruction of the fractured distal radius.

Surface Coating of Polytetrafluoroethylene with Extracellular Matrix and Anti-CD34 Antibodies Facilitates Endothelialization and Inhibits Platelet Adhesion Under Sheer Stress

Expanded polytetrafluoroethylene (ePTFE) polymers do not support endothelialization because of nonconductive characteristics towards cellular attachment. Inner surface modification of the grafts can improve endothelialization and increase the long-term patency rate of the ePTFE vascular grafts. Here we reported a method of inner-surface modification of ePTFE vascular graft with extracellular matrix (ECM) and CD34 monoclonal antibodies (CD34 mAb) to stimulate the adhesion and proliferation of circulating endothelial progenitor cells on ePTFE graft to enhance graft endothelialization. The inner surface of ECM-coated ePTFE grafts were linked with CD34 mAb in the presence of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/N-hydroxysuccinimide (EDC/NHS) solution and the physicochemical properties, surface morphology, biocompatibility, and hemocompatibility of the grafts were studied. The hydrophilicity of CD34 mAb-coated graft inner surface was significantly improved. Fourier transform infrared spectroscopy analysis confirmed ECM and CD34 mAb cross-linking in the ePTFE vascular grafts with our method. Scanning electron microscopy analysis showed protein layer covering uniformly on the inner surface of the modified grafts. The cell-counting kit-8 (CCK-8) assay confirmed that the modified graft has no obvious cytotoxicity. The modified graft showed a low hemolytic rate (0.9%) in the direct contact hemolysis test, suggesting the modification improved hemocompatibility of biopolymers. The modification also decreased adhesion of platelets, while significantly increased the adhesion of endothelial cells on the grafts. We conclude that our method enables ePTFE polymers modification with ECM and CD34 mAb, facilitates endothelialization, and inhibits platelet adhesion on the grafts, thus may increase the long-term patency rate of the prosthetic bypass grafts.

Influence of Peanut Cultivars and Environmental Conditions on the Diversity and Community Composition of Pod Rot Soil Fungi in China

Peanut yield and quality are seriously affected by pod rot pathogens worldwide, especially in China in recent years. The goals of this study are to analyze the structure of fungal communities of peanut pod rot in soil in three peanut cultivars and the correlation of pod rot with environmental variables using 454 pyrosequencing. A total of 46,723 internal transcribed spacer high-quality sequences were obtained and grouped into 1,706 operational taxonomic units at the 97% similarity cut-off level. The coverage, rank abundance, and the Chao 1 and Shannon diversity indices of the operational taxonomic units were analyzed. Members of the phylum Ascomycota were dominant, such as Fusarium, Chaetomium, Alternaria, and Sordariomycetes, followed by Basidiomycota. The results of the heatmap and redundancy analysis revealed significant variation in the composition of the fungal community among the three cultivar samples. The environmental conditions in different peanut cultivars may also influence on the structure of the fungal community. The results of this study suggest that the causal agent of peanut pod rot may be more complex, and cultivars and environmental conditions are both important contributors to the community structure of peanut pod rot fungi.

Endovascular treatment of aortic lesions involving branch vessels with multi-layer bare stents / 中华外科杂志

Aortic lesions involving branch vessels have always been a great challenge for vascular surgeons. Endovascular repair are growing to take place of traditional open repair for less invasion and lower complication rates. Despite rapid developments in endovascular instruments have been achieved in the last decade, and endovascular techniques such as fenestration stents have been applied in the treatment of aortic lesions involving branch vessels. However, endovascular repairing aortic lesions involving branch vessels remains being restricted by rigorous indication selection as well as requirements of advanced experiences and sophisticated skills. Recently, several studies about treating aortic lesion involving branch vessels with multi-layer bare stents have been reported, the primary results were encouraging and brought new visions for the management of such disease. More approving clinical evidences about the safety and efficacy of multi-layer stents are anticipated.
