Abstract
The rhaphidophorid subfamily Rhaphidophorinae, distributed from South Asian to Australia, comprises 7 extant genus and 160 species. In China, the subfamily are poorly understood. Based on the occurrence data and climate data, ecological niche model can be used as a tool for species discovery. Herein we predict the potential distribution of Chinese Rhaphidophorinae using MAXENT under R environment. The mean temperature of coldest quarter plays an important role in the distribution of true cave cricket in China. Our potential map suggested the main concentrated area of the subfamily's range is in Yunnan, while expanding to the east, there is an obviously geographical barrier in Guangxi. Considering the diversity of rhaphidophorids in China is not well known, we hope that the combining ecological niche model can serve as a guide to future survey expeditions in China.

Abstract
The study aimed to screen potential key genes, and their targeted miRNAs and transcription factors (TFs) that were related to diffuse large B-cell lymphoma (DLBCL), and explore potential therapeutic targets for the progression of DLBCL. Dataset GSE56315 extracted from human tonsils was downloaded from Gene Expression Omnibus. Limma package was used to identify differential expression genes (DEG) between DLBCL and normal human tonsils samples, and the function and pathway enrichment analyses were performed. Then, functional interaction (FI) networks analyses of DEGs were implemented, and modules were extracted. Additionally, DLBCL-related miRNAs were predicted based on miR2disease database. Thereafter, TF-target DEGs and miRNAs targeted genes were respectively obtained. Finally, the integrated network of TF-target-miRNA was constructed. A total of 4,495 DEGs were identified between DLBCL and NHT samples. Among them, 114 up-regulated DEGs were contained in 8 modules of FI network, while 189 down-regulated DEGs were contained in 12 sub-modules. In addition, most DEGs were enriched in the function of "DNA binding" and pathways of "chemokine signaling pathway", "phosphatidylinositol signaling system" and "RNA degradation". Moreover, 19 miRNAs related with DLBCL were downloaded from Mirwalk2. Furthermore, miRNAs of miR-21-5p, miR-155 and miR-17-5p, the TF of STAT1, and DEGs such as NUF2, CCR1, PIK3R1, SMC1A, FOXK1 and CNOT6L had high degrees in the integrated networks of TF-target-miRNA. DEGs like NUF2, CCR1, PIK3R1, SMC1A, FOXK1 and CNOT6L might be closely associated with the pathogenesis of DLBCL.

Abstract
This study aimed to determine the value of HA/HAase for detecting bladder cancer on the basis of preceding statistical performance. PubMed, Springer Link, Web of Science and Cochrane Library were systematically searched to identify potentially relevant published articles by using the key words: "bladder cancer or bladder tumor or bladder carcinoma", "hyaluronic acid or hyaluronan", "hyaluronidase or HAase". The methodological quality of each study was assessed by QUADAS-2. According to the inclusive and exclusive criteria, 8 articles were identified and methodologically analyzed by STATA 12.0 software package.The results showed that the pooled sensitivity of HA and HAase was 0.832 (95% confidence interval [CI]: 0.798, 0.861) and 0.834 (95% CI: 0.756, 0.891) respectively, the pooled specificity was 0.886 (95% CI: 0.852, 0.913) and 0.860 (95% CI: 0.801, 0.904), and the area under the summary ROC cure (AUC) was 0.90 (95% CI: 0.87, 0.92) and 0.91 (95% CI: 0.88, 0.93), respectively. Simultaneously the diagnostic accuracy of the combination of HA and HAase showed that the pooled sensitivity was 0.908 (95% CI: 0.879, 0.931), the pooled specificity was 0.825 (95% CI: 0.789, 0.856) and AUC was 0.94 (95% CI: 0.91, 0.95), indicating a relatively higher accuracy than HA and HAase alone. This meta-analysis strongly suggests that HA/HAase could be used as biomarkers for the diagnosis of bladder cancer.

Abstract
OBJECTIVES To analyze the characteristics of medical malpractices in orthopaedic surgeries, to explore principles and methods in medical legal identification, and to provide basic data for uniform medicolegal standard for the future medical identification. METHODS A retrospective analysis was conducted on 100 cases of medical malpractices in orthopaedic surgery, among the 364 cases archived in Medicolegal Expertise Center of Xi'an Jiaotong University during 2002-2015. RESULTS In the 100 cases of orthopedic medical malpractices, with 104 hospitals involved in, 95 cases were judged with medical errors and the other 9 cases with no error. The top 3 reasons for errors were (1) inadequate observation or estimation of diseases (27.9%), (2) intraoperative improper operation (17.3%), and (3) delayed or missed diagnosis and treatment (12.5%). The consequences of medical malpractices were mostly disability (61%), followed by prolonged diseases (31%) and death (8%). With regard to the causal relationship between medical errors and consequences, 95 cases (91.4%) were with causality and the other 9 cases (8.6%) with no causality. Specifically, 56 cases (53.9%) were with medical errors as the secondary causes accounting for 25% causative potency, and 20 cases (19.2%) were with medical errors as the major causes accounting for 75% causative potency. CONCLUSIONS It is pivotally important for determining the causative potency of medical errors to analyse the causes of damages in orthopaedic surgery and to distinguish subjective factors from objective ones of medical errors.

Singleton molecular species delimitation based on COI-5P barcode sequences revealed high cryptic/undescribed diversity for Chinese katydids (Orthoptera: Tettigoniidae). BMC Evol Biol 2019; 19:79. [PMID: 30871464 PMCID: PMC6419471 DOI: 10.1186/s12862-019-1404-5] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Accepted: 02/25/2019] [Indexed: 12/14/2022] Open
Abstract
Background DNA barcoding has been developed as a useful tool for species discrimination. Several sequence-based species delimitation methods, such as Barcode Index Number (BIN), REfined Single Linkage (RESL), Automatic Barcode Gap Discovery (ABGD), a Java program uses an explicit, determinate algorithm to define Molecular Operational Taxonomic Unit (jMOTU), Generalized Mixed Yule Coalescent (GMYC), and Bayesian implementation of the Poisson Tree Processes model (bPTP), were used. Our aim was to estimate Chinese katydid biodiversity using standard DNA barcode cytochrome c oxidase subunit I (COI-5P) sequences. Results Detection of a barcoding gap by similarity-based analyses and clustering-base analyses indicated that 131 identified morphological species (morphospecies) were assigned to 196 BINs and were divided into four categories: (i) MATCH (83/131 = 64.89%), morphospecies were a perfect match between morphospecies and BINs (including 61 concordant BINs and 22 singleton BINs); (ii) MERGE (14/131 = 10.69%), morphospecies shared its unique BIN with other species; (iii) SPLIT (33/131 = 25.19%, when 22 singleton species were excluded, it rose to 33/109 = 30.28%), morphospecies were placed in more than one BIN; (iv) MIXTURE (4/131 = 5.34%), morphospecies showed a more complex partition involving both a merge and a split. Neighbor-joining (NJ) analyses showed that nearly all BINs and most morphospecies formed monophyletic cluster with little variation. The molecular operational taxonomic units (MOTUs) were defined considering only the more inclusive clades found by at least four of seven species delimitation methods. Our results robustly supported 61 of 109 (55.96%) morphospecies represented by more than one specimen, 159 of 213 (74.65%) concordant BINs, and 3 of 8 (37.5%) discordant BINs. Conclusions Molecular species delimitation analyses generated a larger number of MOTUs compared with morphospecies. If these MOTU splits are proven to be true, Chinese katydids probably contain a seemingly large proportion of cryptic/undescribed taxa. Future amplification of additional molecular markers, particularly from the nuclear DNA, may be especially useful for specimens that were identified here as problematic taxa.

Abstract
BACKGROUND Black kidney transplant patients experience inferior outcomes compared with other ethnicities. Because scrutiny is required when immunosuppressant drugs are used in such at-risk populations, we report the first large-scale clinical efficacy data assessing prolonged-release tacrolimus (PR-T) in black de novo kidney transplant patients. METHODS AND MATERIALS We used logistic regression and proportionate hazards to compare a composite outcome measure (biopsy-proven acute rejection, graft loss, mortality, and loss to follow-up) in black and white patients in treatment groups longer than 24 weeks, from 3 large Phase III randomized controlled trials. Secondary endpoints included tacrolimus trough concentration, dose, and estimated glomerular filtration rate. RESULTS The study included 2162 patients whose treatments belonged to two categories (immediate-release tacrolimus: 77 black patients, 721 white patients; and PR-T: 87 black patients, 1277 white patients). Despite demographic factors generally predictive of worse outcomes, efficacy failure among black patients who received PR-T was non-inferior to that among white patients who received either therapy. Compared with immediate-release tacrolimus, black patients who received PR-T achieved stable tacrolimus concentrations 2.5 times faster (21 vs 56 days, P = .04), and more achieved stable target concentrations (76.7% vs 69.3%). Treatment-emergent adverse events were consistent with those reported separately in pivotal trials. CONCLUSIONS Overall, black patients who received PR-T achieved non-inferior outcomes compared to white patients, despite higher pretransplant risk among black patients. Moreover, PR-T improved the time to achieve, and the likelihood of reaching, stable therapeutic concentrations among black patients, suggesting that PR-T could improve the consistency of tacrolimus exposure in this patient population.

Abstract
The relationships among the Phlugiolopsis species are poorly understood. In this paper, three new subgenera are proposed and four new species are described from Yunnan, China. The microstructures of male stridulatory files are examined for selected species of Phlugiolopsis using scanning electron micrographs (SEM). Geometric morphometric study of the left tegmen for the genus Phlugiolopsis was carried out to demonstrate the effect of vicariance on species. Differences among species are minute, suggesting that the separation is recent. All examined specimens are deposited in the Museum of Hebei University (HBUM).

Abstract
Objective: To investigate whether there were differences between the three stains for eosinophil counting in nasal polyps. Method: Three serial sections of formalin-fxed, paraffn-embedded tissues of 23 cases of nasal polyps were stained with Congo red,Chromotrope 2R and conventional HE staining, respectively. The stained sections were converted to digital pathology using a digital slice scanner. The qualitative assessment of the staining results was made in terms of specificity, contrast and background staining. Eosinophils were quantitatively evaluated and statistically analyzed using the Image J Analysis System and GraphPad Prism 5 statistical software. Result: Congo red staining and Chromotrope 2R staining were more specific than conventional HE staining. Chromotrope 2R had the lowest background staining. The majority of Congo red staining (n=20) was lighter in the background than in the conventional HE, while a small number of cases (n=3) background staining slightly stronger. Both Congo red staining and Chromotrope 2R staining had statistically significant differences compared with conventional HE staining (P<0.05), but there was no significant difference between Congo red staining and Chromotrope 2R staining (P>0.05). Conclusion: Congo red staining and Chromotrope 2R staining are more suitable for accurate counting of eosinophils, and the use of these two methods contributes to the harmonization of eosinophil count criteria in the ECRSwNP definition.

Abstract
BACKGROUND AND PURPOSE Thrombus permeability assessed on conventional CTA is associated with neurologic outcome in patients with acute ischemic stroke. We aimed to investigate whether dynamic CTA can improve the accuracy of thrombus permeability assessment and its predictive value for outcome. MATERIALS AND METHODS We reviewed consecutive patients with acute ischemic stroke who had occlusion of the M1 segment of the middle artery cerebral artery and underwent pretreatment perfusion CT. Thrombus permeability, determined by thrombus attenuation increase (TAI), was assessed on 26-phase dynamic CTA derived from perfusion CT. TAImax was defined as the maximum TAI among phases; TAIpeak, as TAI of peak arterial phase; TAIcon, as TAI on phase 13. Good outcome was defined as a 3-month mRS score of ≤2. RESULTS One hundred four patients were enrolled in the final analysis. The median TAImax, TAIpeak, and TAIcon were 30.1 HU (interquartile range, 13.0-50.2 HU), 9.5 HU (interquartile range, -1.6-28.7 HU), and 6.6 HU (interquartile range, -5.1-24.4 HU), respectively. Multivariable regression analyses showed that TAImax (OR = 1.027; 95% CI, 1.007-1.048; P = .008), TAIpeak (OR = 1.029; 95% CI, 1.005-1.054; P = .020), and TAIcon (OR = 1.026; 95% CI, 1.002-1.051; P = .037) were independently associated with good outcome. The areas under the ROC curve of TAImax, TAIpeak, and TAIcon in predicting good outcome were 0.734, 0.701, and 0.658, respectively. CONCLUSIONS Thrombus permeability assessed on dynamic CTA could be a better predictor of outcome after reperfusion therapy than that assessed on conventional single-phase CTA.

Abstract
Objective: To investigate the occurrence and degree of radiation-induced injury in vagina after radical radiotherapy of cervical cancer. Methods: A total of 282 cases of patients with cervical cancer were collected from November 2016 to September 2017. All of the above patients underwent radical radiotherapy from 2008 to 2017 in the First Affiliated Hospital of Xi'an Jiaotong University. The patients' International Federation of Gynecology and Obstetrics (FIGO) staging (2009) , brachytherapy dose, whether receive synchronous chemotherapy or not, age and body mass index (BMI) for the occurrence and severity of vaginal radiation injury at different time periods were analyzed by cross-sectional survey method. The single factor would be analyzed by the method of Chi-square test and the multiple factors would be analyzed by logistic regression method to checkout. Results: Of the 282 patients, the incidence of radiation-injury in vaginal was 84.4% (238/282) , with the incidence rate of degree Ⅰ,Ⅱ and Ⅲ radiation injury were respectively 50.7% (143/282), 29.8% (84/282) and 3.9% (11/282; χ(2)=153.375, P<0.05) , and there was no degree Ⅳ. Until the end of the follow-up time, the incidence of radiation-induced injury in vaginal after completing the treatment within 1 year, 1-2 years,>2-<5 years and ≥5 years were respectively 80.0% (24/30) , 87.2% (102/117) , 88.2% (60/68) and 77.6% (52/67; χ(2)=4.231, P=0.238) . There were 30 cases be followed within 1 year after treatment, the incidence rate of degreeⅠ,Ⅱ and Ⅲ of radiation injury in vagina was 60.0% (18/30) , 20.0% (6/30) and 0, respectively (χ(2)=28.636, P<0.05). There were 117 cases be followed between 1-2 years after treatment, the incidence rate of degreeⅠ,Ⅱ and Ⅲ vaginal radiation-induced injury were 54.7% (64/117) , 29.9% (35/117) and 2.6% (3/117) , respectively (χ(2)=77.198, P<0.05) . There were 68 cases be followed between >2-<5 years after treatment, the incidence rate of degree Ⅰ,Ⅱ and Ⅲ vaginal radiation-induced injury were 51.5% (35/68) ,33.8% (23/68) and 2.9% (2/68) , respectively (χ(2)=39.525, P<0.05) . There were 67 cases be followed ≥5 years after treatment, the incidence rate of degree Ⅰ,Ⅱ and Ⅲ vaginal radiation injury were 38.8% (26/67) , 29.9% (20/67) and 9.0% (6/67) , respectively (χ(2)=16.395, P<0.05) . The single-factor analysis result indicated that the brachytherapy dose had an obvious effect on vaginal radiation-induced injury (χ(2)=5.344, P=0.021) ; however, other factors, such as age, BMI, FIGO stages and synchronous chemotherapy, had no obvious effect on vaginal radiation-induced injury (all P>0.05) . The multifactor analysis indicated that the brachytherapy dose was an independent factor affecting the occurrence of vaginal radiation-induced injury (P=0.043) . Conclusion: After the radical radiotherapy of cervical cancer, the vaginal radiation-induced injury is associated with the dose of brachytherapy.

Abstract
BACKGROUND AND PURPOSE The multisegment clot sign has been observed at the site of large-artery occlusion in patients with acute ischemic stroke. This study aimed to assess its occurrence rate and relationship with stroke etiologies in patients with acute intracranial large-artery occlusion. MATERIALS AND METHODS We included consecutive patients with acute ischemic stroke who had acute intracranial large-artery occlusion and underwent perfusion CT within 8 hours after stroke onset. The multisegment clot sign was assessed on dynamic CT angiography derived from perfusion CT. The stroke etiologies were defined by the international Trial of Org 10172 in Acute Stroke Treatment criteria. Poisson regression analyses and diagnostic testing were used to investigate the relationship between the multisegment clot sign and stroke etiologies. RESULTS Finally, 194 patients with intracranial large-artery occlusion were enrolled. According to the Trial of Org 10172 in Acute Stroke Treatment criteria, 110 (56.7%) patients were diagnosed with cardioembolism; 43 (22.2%), with large-artery atherosclerosis; and 41 (21.1%), with undetermined etiology. The multisegment clot sign was found in 74 (38%) patients. Poisson regression analysis showed that the presence of the multisegment clot sign was significantly higher in patients with cardioembolism than in those with large-artery atherosclerosis (52.7% versus 9.3%; prevalence ratio, 1.53; 95% confidence interval, 1.03-2.90; P = .037). For determined etiologies, the sensitivity, specificity, and positive and negative predictive values of the multisegment clot sign for predicting cardioembolism were 52.7%, 90.7%, 93.5%, and 42.9%, respectively. CONCLUSIONS The presence of the multisegment clot sign on dynamic CTA specifically indicates intracranial large-artery occlusion caused by an embolism from a cardiac source, which may be useful for acute management and secondary prevention of stroke.

Abstract
Objective: To analyze the relationship between clinicopathologic characteristics of pseudomyxoma peritonei (PMP) and its prognosis. Methods: Fifty-two cases of PMP collected from 2012 to 2017 at Beijing Shijitan Hospital, Capital Medical University were reviewed using the diagnostic criteria of WHO 2010. The histopathologic features, including original location, neural invasion and calcification were observed; and the relationship with prognosis was analyzed. Immunohistochemical staining for CK7, CK20 and CDX2 was performed on all cases. ER, PR, and p16 were additionally performed on those without clear origin. Results: Patients' mean age was 52.0 years, and included 29 males and 23 females. Thirty-two cases were derived from appendix; among them, 23 were low grade and 29 were high grade. Signet ring-cells, neural invasion and calcification were detected in 15, 12 and 9 cases respectively. Neural invasion was associated with adverse prognosis (P=0.025) and signet ring cell morphology (P<0.01). Prognosis was not related to gender, age, original location or grade. Conclusion: Neural invasion is not uncommon in PMP and predicts a bad prognosis.

Abstract
BACKGROUND AND PURPOSE Previous studies showed conflicting results concerning the value of CBF maps obtained from arterial spin-labeling MR imaging in grading gliomas. This study was performed to investigate the effectiveness of CBF maps derived from 3D pseudocontinuous arterial spin-labeling in preoperatively assessing the grade, cellular proliferation, and prognosis of gliomas. MATERIALS AND METHODS Fifty-eight patients with pathologically confirmed gliomas underwent preoperative 3D pseudocontinuous arterial spin-labeling. The receiver operating characteristic curves for parameters to distinguish high-grade gliomas from low-grade gliomas were generated. Pearson correlation analysis was used to assess the correlation among parameters. Survival analysis was conducted with Cox regression. RESULTS Both maximum CBF and maximum relative CBF were significantly higher in high-grade gliomas than in low-grade gliomas (P < .001). The areas under the curve for maximum CBF and maximum relative CBF in distinguishing high-grade gliomas from low-grade gliomas were 0.828 and 0.863, respectively. Both maximum CBF and maximum relative CBF had no correlation with the Ki-67 index in all subjects and had a moderate negative correlation with the Ki-67 index in glioblastomas (r = -0.475, -0.534, respectively). After adjustment for age, a higher maximum CBF (P = .008) and higher maximum relative CBF (P = .005) were associated with worse progression-free survival in gliomas, while a higher maximum relative CBF (P = .033) was associated with better overall survival in glioblastomas. CONCLUSIONS 3D pseudocontinuous arterial spin-labeling-derived CBF maps are effective in preoperative evaluation of gliomas. Although gliomas with a higher blood flow are more malignant, glioblastomas with a lower blood flow are likely to be more aggressive.
