Correlation between blood glucose and cerebrospinal fluid glucose levels in patients with differences in glucose metabolism.

Objectives: We aimed to determine a method to identify normal cerebrospinal fluid (CSF) glucose levels by examining the correlation between blood and CSF glucose levels in patients with normal and abnormal glucose metabolism. Methods: One hundred ninety-five patients were divided into two groups according to their glucose metabolism. The glucose levels were obtained from CSF and fingertip blood at 6, 5, 4, 3, 2, 1, and 0 h before lumbar puncture. SPSS 22.0 software was used for the statistical analysis. Results: In both the normal and abnormal glucose metabolism groups, CSF glucose levels increased with blood glucose levels at 6, 5, 4, 3, 2, 1, and 0 h before lumbar puncture. In the normal glucose metabolism group, the CSF/blood glucose ratio range was 0.35-0.95 at 0-6 h before lumbar puncture, and the CSF/average blood glucose ratio range was 0.43-0.74. In the abnormal glucose metabolism group, the CSF/blood glucose ratio range was 0.25-1.2 at 0-6 h before lumbar puncture, and the CSF/average blood glucose ratio range was 0.33-0.78. Conclusion: The CSF glucose level is influenced by the blood glucose level 6 h before lumbar puncture. In patients with normal glucose metabolism, direct measurement of the CSF glucose level can be used to determine whether the CSF level is normal. However, in patients with abnormal or unclear glucose metabolism, the CSF/average blood glucose ratio should be used to determine whether the CSF glucose level is normal.

Objective:To summarize our experience in 13 cases of intestinal autotransplantation (IATx) after resection of lesions involving the roots of mesenteric vessels.Methods:The clinical data of 13 patients undergoing IATx in Xijing hospital were retrospectively analyzed. The etiology, surgical procedure and complications were analyzed. The patients were followed up by telephone and regular evaluations.Results:All 13 cases of IATx were successfully completed. For 12 patients who were diagnosed with tumors involving the mesenteric roots, the tumors were removed for cure intent avoiding massive intestinal resection. Pancreaticoduodenectomy was carried out simultaneously in 11 cases. The postoperative complication rate was 85% (11/13). The autograft was resected in 1 patient on the 1st postoperative day due to necrosis from mesenteric thrombosis, leading to short bowel syndrome. One-year survival was 69% (9/13). Among 4 deaths, 1 patient died of liver metastasis, and another died of liver and lung metastases. Five patients were alive 2 years postoperatively.Conclusion:IATx while-technically challenging, avoiding short small bowel syndrome in properly selected patients after resection of lesions especially benign ones involving the roots of mesenteric vessels that were traditionally considered to be "unresectable".

Metagenomic Next-Generation Sequencing for Diagnosis of Infectious Encephalitis and Meningitis: A Large, Prospective Case Series of 213 Patients.

Purpose: We assessed the performance of metagenomic next-generation sequencing (mNGS) in the diagnosis of infectious encephalitis and meningitis. Methods: This was a prospective multicenter study. Cerebrospinal fluid samples from patients with viral encephalitis and/or meningitis, tuberculous meningitis, bacterial meningitis, fungal meningitis, and non-central nervous system (CNS) infections were subjected to mNGS. Results: In total, 213 patients with infectious and non-infectious CNS diseases were finally enrolled from November 2016 to May 2019; the mNGS-positive detection rate of definite CNS infections was 57.0%. At a species-specific read number (SSRN) ≥2, mNGS performance in the diagnosis of definite viral encephalitis and/or meningitis was optimal (area under the curve [AUC] = 0.659, 95% confidence interval [CI] = 0.566-0.751); the positivity rate was 42.6%. At a genus-specific read number ≥1, mNGS performance in the diagnosis of tuberculous meningitis (definite or probable) was optimal (AUC=0.619, 95% CI=0.516-0.721); the positivity rate was 27.3%. At SSRNs ≥5 or 10, the diagnostic performance was optimal for definite bacterial meningitis (AUC=0.846, 95% CI = 0.711-0.981); the sensitivity was 73.3%. The sensitivities of mNGS (at SSRN ≥2) in the diagnosis of cryptococcal meningitis and cerebral aspergillosis were 76.92 and 80%, respectively. Conclusion: mNGS of cerebrospinal fluid effectively identifies pathogens causing infectious CNS diseases. mNGS should be used in conjunction with conventional microbiological testing.

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.

Alterations of White Matter Connectivity in Preschool Children with Autism Spectrum Disorder.

Purpose To investigate the topologic architecture of white matter connectivity networks in preschool-aged children with a diagnosis of autism spectrum disorder (ASD) versus typical development (TD). Materials and Methods Forty-two participants were enrolled, including 21 preschool children with ASD (14 male children and seven female children; mean age, 4.56 years ± 0.97 [standard deviation]) and 21 children with TD (11 males and 10 females; mean age, 5.13 years ± 0.82). The diagnosis of ASD was determined according to the Diagnostic and Statistical Manual of Mental Disorders Global Assessment of Functioning scores (mean score, 8.00 ± 0.50). All participants underwent diffusion-tensor imaging (DTI) and T2-weighted imaging on a 3-T magnetic resonance system. A graph theoretical analysis was applied to investigate the topologic organization of the brain network including global and local topologic parameters. Statistical analysis was then performed for the comparison between the groups. Results Compared with the TD group, children with ASD demonstrated shortened characteristic path length (t1 = 0.536, t2 = 0.534, t3 = 0.523, t4 = 0.510, and t5 = 0.501; P < .05) and increased global efficiency (t1 = 0.499, t2 = 0.497, t3 = 0.486, t4 = 0.473, and t5 = 0.465; P < .05) and clustering coefficient (t1 = 0.673, t2 = 0.750, t3 = 0.757, t4 = 0.738, and t5 = 0.741; P < .05). Significant increases in nodal efficiency were mainly found in left pallidum (0.037 vs 0.032, respectively; P < .01) and right caudate nucleus (0.037 vs 0.032, respectively; P < .01) of the basal ganglia network. Conclusion Significantly altered patterns of global and local brain network topography may underlie the abnormal brain development in preschool children with ASD compared with those who have TD. The identification of altered structural connectivity in basal ganglia and paralimbic-limbic networks may point toward potential imaging biomarkers for preschool-age patients with ASD. © RSNA, 2018.

Two de novo variations identified by massively parallel sequencing in 13 Chinese families with children diagnosed with autism spectrum disorder.

Autism spectrum disorder (ASD) is a genetically heterogeneous neurodevelopmental disorder characterized by impairments in social interaction and communication, and by restricted and repetitive behaviors. The genetic architecture of ASD has been elucidated, including chromosomal rearrangements, de novo or inherited rare variants, and copy number variants. However, the genetic mechanism of Chinese families with ASD children is explored rarely. To identify genetic pathogenesis, we performed massively parallel sequencing on 13 Chinese ASD trio families, and found two de novo variations. The novel de novo splice alteration c.664 + 2T > G in the DEAF1 gene and the novel de novo missense mutation c.95 C > T in the AADAT gene associated with ASD may be important clues for exploring the etiology of this disorder.

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.

The Management of Superior Mesenteric Artery Aneurysm: Experience with 16 Cases in a Single Center.

BACKGROUND: Superior mesenteric artery aneurysm (SMAA) represents a rare but potentially fatal condition. This study aimed to present the individual management protocol of SMAA in our center and to discuss a potential preliminary treatment algorithm. METHODS: SMAA patients treated in our center between January 2007 and December 2014 were retrospectively reviewed on January 2015. RESULTS: Sixteen patients with SMAA were identified, including 1 female and 15 males, with a mean age of 48.9 ± 12.9 years. Three patients (3/16, 18.8%) were treated by multiple overlapping bare stents and one (1/16, 6.3%) initially by a single bare stent. Two cases (2/16, 12.5%) were treated by a covered stent implantation, but one of those suffered from SMAA rupture 7 days later, whereas the other had inner-stent thrombosis one month after discharge and died from multiple organ-dysfunction syndrome. Nine patients (9/16, 56.2%) received conservative therapy, one of who received multiple overlapping bare stents implantations for persistent abdominal pain. One patient underwent open surgery. There were 2 major complications, with no death during hospitalization and 1 death during follow-up. CONCLUSIONS: SMAA treatment needs to be individually prescribed, based on clinical manifestation, anatomy, and etiology. Multiple overlapping bare stents are safe and effective in selective patients with SMAA, and covered stents should be used with caution to avoid covering proximal branches; open surgery should be reserved for patients with suspected intestinal necrosis.

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.

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.
