RESUMEN

Rosalia funebris (RFUNE; Cerambycidae), the banded alder borer, is a longhorn beetle whose larvae feed on the wood of various economically and ecologically significant trees in western North America. Adults are short-lived and not known to consume plant material substantially. We sequenced, assembled and annotated the RFUNE genome using HiFi and RNASeq data. We documented genome architecture and gene content, focusing on genes putatively involved in plant feeding (phytophagy). Comparisons were made to the well-studied genome of the Asian longhorned beetle (AGLAB; Anoplophora glabripennis) and other Cerambycidae. The 814 Mb RFUNE genome assembly was distributed across 42 contigs, with an N50 of 30.18 Mb. Repetitive sequences comprised 60.27 % of the genome, and 99.0 % of expected single-copy orthologous genes were fully assembled. We identified 12657 genes, fewer than in the four other species studied, and 46.4 % fewer than for Aromia moschata (same subfamily as RFUNE). Of the 7258 orthogroups shared between RFUNE and AGLAB, 1461 had more copies in AGLAB and 1023 had more copies in RFUNE. We identified 240 genes in RFUNE that putatively arose via horizontal transfer events. The RFUNE genome encoded substantially fewer putative plant cell wall degrading enzymes than AGLAB, which may relate to the longer-lived plant-feeding adults of the latter species. The RFUNE genome provides new insights into cerambycid genome architecture and gene content and provides a new vantage point from which to study the evolution and genomic basis of phytophagy in beetles.

RESUMEN

The Diaprepes root weevil (DRW), Diaprepes abbreviatus, is a broadly polyphagous invasive pest of agriculture in the southern United States and the Caribbean. Its genome was sequenced, assembled, and annotated to study genomic correlates of specialized plant-feeding and invasiveness and to facilitate the development of new methods for DRW control. The 1.69 Gb D. abbreviatus genome assembly was distributed across 653 contigs, with an N50 of 7.8 Mb and the largest contig of 62 Mb. Most of the genome was comprised of repetitive sequences, with 66.17% in transposable elements, 5.75% in macrosatellites, and 2.06% in microsatellites. Most expected orthologous genes were present and fully assembled, with 99.5% of BUSCO genes present and 1.5% duplicated. One hundred and nine contigs (27.19 Mb) were identified as putative fragments of the X and Y sex chromosomes, and homology assessment with other beetle X chromosomes indicated a possible sex chromosome turnover event. Genome annotation identified 18,412 genes, including 43 putative horizontally transferred (HT) loci. Notably, 258 genes were identified from gene families known to encode plant cell wall degrading enzymes and invertases, including carbohydrate esterases, polysaccharide lyases, and glycoside hydrolases (GH). GH genes were unusually numerous, with 239 putative genes representing 19 GH families. Interestingly, several other beetle species with large numbers of GH genes are (like D. abbreviatus) successful invasive pests of agriculture or forestry.

RESUMEN

BACKGROUND: The phylogenetic position and classification of Athysanini are poorly defined, as it includes a large group of polyphyletic genera that have historically been assigned to it mainly because they still exhibit the most typical deltocephaline genitalic and external body characters but lack the distinctive characteristics that other tribes possess. The bamboo-feeding leafhopper genus Abrus belong to the tribe Athysanini of subfamily Deltocephalinae, which currently comprises 19 valid described species, and are limited to the Oriental and Palaearctic regions in China. Although the taxonomy of Abrus are well updated, the references on comparative mitogenomic analyses of Abrus species are only known for a single species. In this study, we sequenced and analyzed the complete mitochondrial genomes (mitogenomes) of Abrus daozhenensis Chen, Yang & Li, 2012 (16,391bp) and A. yunshanensis Chen, Yang & Li, 2012 (15,768bp) (Athysanini), and compared with published mitogenome sequence of A. expansivus Xing & Li, 2014 (15,904bp). RESULTS: These Abrus species shared highly conserved mitogenomes with similar gene order to that of the putative ancestral insect with 37 typical genes and a non-coding A + T-rich region. The nucleotide composition of these genomes is highly biased toward A + T nucleotides (76.2%, 76.3%, and 74.7%), AT-skews (0.091 to 0.095, and 0.095), negative GC-skews (- 0.138, - 0.161, and - 0.138), and codon usage. All 22 tRNA genes had typical cloverleaf secondary structures, except for trnS1 (AGN) which lacks the dihydrouridine arm, and distinctively trnG in the mitogenome of A. expansivus lacks the TψC arm. Phylogenetic analyses based on 13 PCGs, 2 rRNA genes, and 22 tRNA genes consistently recovered the monophyletic Opsiini, Penthimiini, Selenocephalini, Scaphoideini, and Athysanini (except Watanabella graminea, previously sequenced species as Chlorotettix nigromaculatus) based on limited available mitogenome sequence data of 37 species. CONCLUSION: At present, Abrus belongs to the tribe Athysanini based on both morphological and molecular datasets, which is strongly supported in present phylogenetic analyses in both BI and ML methods using the six concatenated datasets: amino acid sequences and nucleotides from different combinations of protein-coding genes (PCGs), ribosomal RNA (rRNAs), and transfer RNA (tRNAs). Phylogenetic trees reconstructed herein based on the BI and ML analyses consistently recovered monophylitic Athysanini, except Watanabella graminea (Athysanini) in Opsiini with high support values.

RESUMEN

Hypokalemia causes ectopic heartbeats, but the mechanisms underlying such cardiac arrhythmias are not understood. In reduced serum K+ concentrations that occur under hypokalemia, K2P1 two-pore domain K+ channels change ion selectivity and switch to conduct inward leak cation currents, which cause aberrant depolarization of resting potential and induce spontaneous action potential of human cardiomyocytes. K2P1 is expressed in the human heart but not in mouse hearts. We test the hypothesis that K2P1 leak cation channels contribute to ectopic heartbeats under hypokalemia, by analysis of transgenic mice, which conditionally express induced K2P1 specifically in hearts, mimicking K2P1 channels in the human heart. Conditional expression of induced K2P1 specifically in the heart of hypokalemic mice results in multiple types of ventricular ectopic beats including single and multiple ventricular premature beats as well as ventricular tachycardia and causes sudden death. In isolated mouse hearts that express induced K2P1, sustained ventricular fibrillation occurs rapidly after perfusion with low K+ concentration solutions that mimic hypokalemic conditions. These observed phenotypes occur rarely in control mice or in the hearts that lack K2P1 expression. K2P1-expressing mouse cardiomyocytes of transgenic mice much more frequently fire abnormal single and/or rhythmic spontaneous action potential in hypokalemic conditions, compared to wild type mouse cardiomyocytes without K2P1 expression. These findings confirm that K2P1 leak cation channels induce ventricular ectopic beats and sudden death of transgenic mice with hypokalemia and imply that K2P1 leak cation channels may play a critical role in human ectopic heartbeats under hypokalemia.

RESUMEN

Inocelliidae is one of the two extant families of the holometabolan order Raphidioptera (snakeflies), with the modern fauna represented by seven genera and 44 species. The evolutionary history of the family is little-known. Here we present the first phylogenetic and biogeographical analyses based on a worldwide sampling of taxa and datasets combined with morphological characters and mitochondrial genomes, aiming to investigate the intergeneric phylogeny and historical biogeography of Inocelliidae. The phylogenetic inference from the combined analysis of morphological and molecular data recovered the sister-group relationship between a clade of (Negha + Indianoinocellia) + Sininocellia and a clade of Fibla + the Inocellia clade (interiorly nested by Amurinocellia and Parainocellia). Amurinocellia stat.r. and Parainocellia stat.r. et emend.n. are relegated to subgeneric status within Inocellia, whereas a newly erected subgenus of Inocellia, Epinocellia subgen.n., accommodates the former Parainocellia burmana (U. Aspöck and H. Aspöck, 1968) plus a new species Inocellia (Epinocellia) weii sp.n. Further, the Inocellia crassicornis group constitutes the nominotypical subgenus Inocellia stat.n., but the Inocellia fulvostigmata group is paraphyletic. Diversification within Inocelliidae is distinguished by an Eocene divergence leading to extant genera and a Miocene radiation of species. A biogeographical scenario depicts how the diverse inocelliid fauna from East Asia could have originated from western North America via dispersal across the Beringia during the early Tertiary, and how the Miocene ancestors of Inocellia could have accomplished long-distance dispersals via the Tibet-Himalayan corridor or eastern Palaearctic to western Palaearctic. Our results shed new light specifically on the evolution of Inocelliidae and, in general, the Raphidioptera.

RESUMEN

BACKGROUND: Visfatin has been reported to be closely related to cardiovascular diseases associated with inflammation, but the correlation between visfatin and ventricular arrhythmia (VA) has not been discussed yet. The study aims to explore the association between serum visfatin concentrations and VA in patients. METHODS: Sixty-seven hospitalized patients diagnosed with VA and 131 control subjects were enrolled in this crosssectional study between May 20, 2017 and November 8, 2019. Classification of VA types was based on the presence of structural heart disease (SHD). The patients' blood samples were collected to examine their serum levels of visfatin. Results were analyzed using analysis of variance and t-test. Furthermore, binary logistic regression analysis was used to validate whether elevated visfatin was independently associated with VA. RESULTS: Compared with the controls (mean age, 64.2 ± 13.2 years; 71% of men), the patients with VA (68.2 ± 11.6 years, 58%) had higher serum levels of visfatin (1.80 ± 0.47 ng/mL versus 1.48 ± 0.41 ng/mL; p <0.001). After further grouping patients according to the presence of SHD, the serum levels of VA patients with SHD were the highest. Moreover, binary logistic regression analysis identified age (OR = 1.043; 95% CI, 1.015-1.072, p = 0.003), history of stroke (OR = 2.065; 95% CI, 1.450-5.696, p = 0.005), hsCRP (>10 mg/L) (OR = 4.123; 95% CI, 1.888-9.001, p < 0.001), and elevated visfatin level (>1.40 ng/L) (OR = 3.126; 95% CI, 1.544-6.328, p = 0.002) as independent risk factors with VA. DISCUSSION: Serum visfatin levels were significantly elevated in the patients with VA, and increased with the risk rating of VA.

RESUMEN

BACKGROUND AND AIM: The gut microbiota is associated with colorectal lesions in cases of precancer and colorectal cancer (CRC). However, there are apparent differences in studies on the gut microbiota in the pathogenic sequence from precancer to cancer. Here, we characterize the gut microbiota signatures of colorectal precancer and cancer and test their utility in detecting colorectal lesions in two independent Chinese cohorts. METHODS: Stool samples collected from patients with precancer and CRC were subjected to 16S ribosomal RNA gene sequencing and metagenomic shotgun sequencing analyses, which revealed the microbial signatures of the two disease stages. RESULTS: In comparison with healthy controls, lower microbial richness and diversity were observed in precancer and intensive interbacterial associations were found in CRC. We identified 41 bacteria that showed gradual increases while 12 bacteria showed gradual decreases at the genus level gradually during the development of CRC. Novel CRC-associated pathogenetic species were identified. Species units that contributed to altered microbial functions were identified in CRC patients and healthy controls. The microbial panel showed a comparable ability to fecal immunochemical test (FIT) in detecting CRC. However, the combination of microbes and FIT significantly improved the detection ability and sensitivity of colon lesions based on 18 genera. Microbial network analysis revealed a significant positive correlation among beneficial microbes and a negative correlation in detrimental phenotypes. CONCLUSIONS: Microbial dysbiosis was revealed in colorectal lesions. The combination of microbial markers and FIT improved the CRC detection ability, which might assist in the early diagnosis of CRC.

RESUMEN

Qualitative and quantitative analyses of derivatized phenols in Beijing and in Xinglong were performed from 2016 to 2017 using gas chromatography-mass spectrometry. The results showed substantially more severe pollution in Beijing. Of the 14 compounds detected, the total average concentration was 100 ng/m3 in Beijing, compared with 11.6 ng/m3 in Xinglong. More specifically, concentration of nitro-aromatic compounds (NACs) (81.9 ng/m3 in Beijing and 8.49 ng/m3 in Xinglong) was the highest, followed by aromatic acids (14.6 ng/m3 in Beijing and 2.42 ng/m3 in Xinglong) and aromatic aldehydes (3.62 ng/m3 in Beijing and 0.681 ng/m3 in Xinglong). In terms of seasonal variation, the highest concentrations were found for 4-nitrocatechol in winter in Beijing (79.1 ± 63.9 ng/m3) and 4-nitrophenol in winter in Xinglong (9.72 ± 8.94 ng/m3). The analysis also revealed diurnal variations across different seasons. Most compounds presented higher concentrations at night in winter because of the decreased boundary layer height and increased heating intensity. While some presented higher levels during the day, which attributed to the photo-oxidation process for summer and more biomass burning activities for autumn. Higher concentrations appeared in winter and autumn than in spring and summer, which resulted from more coal combustions and adverse meteorological conditions. The significant correlations among NACs indicated similar sources of pollution. Higher correlations presented within each subgroup than those between the subgroups. Good correlations between levoglucosan and nitrophenols, nitrocatechols, nitrosalicylic acids, with correlation coefficients (r) of 0.66, 0.69 and 0.69, respectively, indicating an important role of biomass burning among primary sources.

RESUMEN

PURPOSE: To determine the safety and efficacy of percutaneous lumbar discectomy (PLD) and percutaneous disc cementoplasty (PDCP) for painful lumbar disc herniation (LDH) in patients >60 years of age. MATERIALS AND METHODS: Sixteen older patients (mean age, 71.00 ± 6.24 years) with painful LDH were treated with PLD and PDCP. The outcome data (the Macnab criteria, visual analog scale score, and Oswestry disability index) were collected preoperatively; at 1 week postoperatively; at posttreatment months 1, 3, and 6; and every 6 months thereafter. In addition, treatment duration, injection volume of bone cement, length of hospital stay, and complications were assessed. RESULTS: Treatment was successful in all patients. The pain relief rate at the last follow-up was 87.5%. Six, 8, and 2 patients showed excellent, good, and fair results, respectively; no patient showed a poor result. The average visual analog scale for back and leg pain decreased from 6.75 ± 1.06 and 7.00 ± 0.89 before the procedure to 2.81 ± 1.60 and 2.87 ± 1.75 at 1 month, 2.79 ± 1.58 and 2.71 ± 1.64 at 6 months, and 2.90 ± 1.73 and 3.00 ± 1.76 at 1 year, respectively. The scores were 2.44 ± 1.63 and 2.44 ± 1.71, respectively, at the last follow-up. The Oswestry disability index also changed after the procedure, with significant differences between baseline scores and those at each follow-up (P < .001). The mean procedure duration, injection volume of bone cement, and length of hospital stay were 55.69 ± 5.86 minutes, 2.50 ± 0.63 mL, and 7.06 ± 2.41 days, respectively. There were no complications. CONCLUSIONS: The combination of PLD and PDCP is feasible, safe, and effective for older patients with painful LDH.

RESUMEN

BACKGROUND Worldwide, colorectal cancer is ranked as the third most prevalent cancer. The natural compound, pancratistatin, extracted from the spider lily, has previously been shown to target apoptosis in cancer cells lines. This study aimed to investigate the effects of pancratistatin in human colorectal cancer cells in vitro. MATERIAL AND METHODS Human colorectal cancer cell lines, including HTC-15 cells, were compared with a normal human colonic fibroblast cell line, CDD-18Co. Cells were treated with increasing doses of pancratistatin. The MTT assay was used to assess cell viability. Fluorescence microscopy using DAPI and Annexin-V/propidium iodide (PI) was used to detect cell apoptosis. Cell autophagy was detected by electron microscopy. Cell migration was evaluated using a wound healing assay, and Western blot determined the expression levels of cell cycle proteins. RESULTS Pancratistatin inhibited the growth of the colorectal cancer cells with an IC50 ranging from 15-25 µM, but had a limited effect in normal CCD-18Co cells, with an IC50 of >100 µM. Pancratistatin reduced HCT-15 cell migration. Growth inhibition due to pancratistatin was associated with morphological changes of HCT-15 cells and included autophagy and apoptosis, and increased expression the autophagic proteins, LC3II, beclin-1, and Bax. Pancratistatin induced arrest of HCT-15 cells at G2/M of the cell cycle and inhibited phosphorylation of cdc2/cyclin-dependent kinase 1 (CDK1) and Cdc25c and the expression of cyclin B1. CONCLUSIONS Pancratistatin inhibited the growth of colorectal cancer cells in vitro by inducing apoptosis, autophagy, and G2/M cell cycle arrest.

RESUMEN

Elemental carbon (EC) or black carbon (BC) in the atmosphere has a strong influence on both climate and human health. In this study, radiocarbon ((14)C) based source apportionment is used to distinguish between fossil fuel and biomass burning sources of EC isolated from aerosol filter samples collected in Beijing from June 2010 to May 2011. The (14)C results demonstrate that EC is consistently dominated by fossil-fuel combustion throughout the whole year with a mean contribution of 79% ± 6% (ranging from 70% to 91%), though EC has a higher mean and peak concentrations in the cold season. The seasonal molecular pattern of hopanes (i.e., a class of organic markers mainly emitted during the combustion of different fossil fuels) indicates that traffic-related emissions are the most important fossil source in the warm period and coal combustion emissions are significantly increased in the cold season. By combining (14)C based source apportionment results and picene (i.e., an organic marker for coal emissions) concentrations, relative contributions from coal (mainly from residential bituminous coal) and vehicle to EC in the cold period were estimated as 25 ± 4% and 50 ± 7%, respectively, whereas the coal combustion contribution was negligible or very small in the warm period.

RESUMEN

OBJECTIVE: To observe the inhibition of NK4 protein in the proliferation of human Raji lymphoma xenografts in nude mice, and to explore its molecular mechanism. METHODS: Models of human Raji lymphoma xenograft transfected with HGF gene were established by subcutaneous inoculation in nude mice. After establishment of the models, the mice received continuous NK4 protein via tail vein for 4 weeks, and the weight and tumor growth were monitored every week. After 8 weeks, the expression of HGF mRNA and c-Met mRNA of tumor tissues was measured by real-time fluorescent quantitation PCR. The apoptotic index (AI) and microvessel density (MVD) were evaluated by terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) and immunohistochemistry, respectively. RESULTS: The models of human Raji lymphoma xenograft were successfully established. Although the animal weights of all groups declined, especially in the groups with NK4 protein injection, there was no statistical significance (P > 0.05). The tumor volume in HGF gene transfected group was larger than those of the control groups (P < 0.01), and there was no statistical significance among the control groups (P > 0.05). However, the tumor volume of the NK4 protein injection group decreased significantly (P < 0.01). Expression of HGF mRNA and c-Met mRNA in HGF gene transfected group increased significantly after injection of NK4 protein (P < 0.01). AI in HGF gene transfected group (33.5% ± 12.3%) was significantly lower than that of control groups (89.1% ± 22.3% vs. 81.9% ± 27.0%, P < 0.05), but became significantly higher (119.1% ± 18.9%) after NK4 protein injection (P < 0.01). MVD in HGF gene transfected group (28.5 ± 2.0) was higher than that of control groups (12.2 ± 1.4, 13.8 ± 1.3, P < 0.01), although declined (15.5 ± 2.5) after NK4 protein injection (P < 0.01). CONCLUSIONS: NK4 protein suppresses significantly the growth of human Raji lymphoma xenografts transfected with HGF gene. The pathogenesis may be involved in promoting tumor cell apoptosis and restraining tumor angiogenesis through competitive interrupting HGF/Met signal pathway.

RESUMEN

ABSTRACT: Introduction: Previous studies have manifested that those sedatives acting on γ-aminobutyric acid A (GABAa) receptor could produce effective brain protection against regional and global ischemic stimulation. The present study was designed to investigate the effect of a novel GABAa receptor agonist, remimazolam postconditioning (RP) on cerebral outcome after global ischemic stimulation induced by cardiac arrest and resuscitation in swine. Methods: A total of 24 swine were used in this study, in which the animals were randomly divided into the following three groups: sham group (n = 6), cardiopulmonary resuscitation (CPR) group (n = 9), and CPR + RP group (n = 9). The experimental model was established by the procedure of 10 min of cardiac arrest and 5 min of CPR. Those resuscitated swine in the CPR + RP group received an intravenous infusion of 2.5 mg/kg of remimazolam within 60 min. Postresuscitation cerebral injury biomarkers and neurological function were evaluated for a total of 24 h. At 24 h after resuscitation, brain cortex was harvested to evaluate the severity of pathologic damage, including tissue inflammation, oxidative stress, apoptosis, and necroptosis. Results: Baseline characteristics and CPR outcomes were not significantly different between the CPR and CPR + RP groups. After resuscitation, significantly greater cerebral injury and neurological dysfunction were observed in the CPR and CPR + RP groups than in the sham group. However, remimazolam postconditioning significantly alleviated cerebral injury and improved neurological dysfunction after resuscitation when compared with the CPR group. At 24 h after resuscitation, tissue inflammation, oxidative stress, and cell apoptosis and necroptosis were significantly increased in the CPR and CPR + RP groups when compared with the sham group. Nevertheless, the severity of pathologic damage mentioned previously were significantly milder in those swine treated with the remimazolam when compared with the CPR group. Conclusions: In a swine model of cardiac arrest and resuscitation, the remimazolam administered after resuscitation significantly improved the markers of postresuscitation cerebral injury and therefore protected the brain against global ischemic stimulation.

RESUMEN

Raphidioptera (snakeflies) are a holometabolan order with the least species diversity but play a pivotal role in understanding the origin of complete metamorphosis. Here, we provide an annotated, chromosome-level reference genome assembly for an Asian endemic snakefly Mongoloraphidia duomilia (Yang, 1998) of the family Raphidiidae, assembled using PacBio HiFi and Hi-C data from female specimens. The resulting assembly is 653.56 Mb, of which 97.90% is anchored into 13 chromosomes. The scaffold N50 is 53.50 Mb, and BUSCO completeness is 97.80%. Repetitive elements comprise 64.31% of the genome (366.04 Mb). We identified 599 noncoding RNAs and predicted 11,141 protein-coding genes in the genome (97.70% BUSCO completeness). The new snakefly genome will facilitate comparison of genome architecture across Neuropterida and Holometabola and shed light on the ecological and evolutionary transitions between Neuropterida and Coleopterida.

RESUMEN

The phylogenetic relationships among the nymphalid subfamilies have largely been resolved using both morphological and molecular datasets, with the exception of a conflicting basal clade position for Libytheinae or Danainae that remains contentious between morphological and molecular studies. Several phylogenomic analyses have found that the danaine clade is sister to other nymphalid subfamilies; however, it largely depends on utilizing different molecular datasets, analysis methods, and taxon sampling. This study aimed to resolve the basal clade position and relationships among subfamilies and tribes of Nymphalinae by combining the most comprehensive available mitogenomic datasets with various analyses methods by incorporating a new Symbrenthia lilaea Hewitson sequence data. Phylogenetic relationships among 11 nymphalid subfamilies and the tribes of Nymphalinae were inferred by combining new and available mitogenomic sequence data from 80 ingroup and six outgroup species. The phylogenetic trees were reconstructed using maximum-likelihood (ML) and Bayesian inference (BI) methods based on five concatenated datasets: amino acid sequences and nucleotides from different combinations of protein-coding genes (PCGs), ribosomal RNA (rRNAs), and transfer RNA (tRNAs). Danainae is well-supported as the basal clade and sister to the remaining nymphalid subfamilies, except for the paraphyletic Libytheinae. Libytheinae was either recovered as a sister to the danaine clade followed by the satyrine clade or sister to the nymphaline + heliconiine clades, and is consistent with recent phylogenetic studies on Nymphalidae. The monophyletic Nymphalinae has been recovered in all analyses and resolves tribal-level relationships with high support values in both BI and ML analyses. We supported the monophyletic Nymphalini as a sister clade to Victorini, Melitaeini, and Kallimini + Junoniini with high supporting values in BI and ML analyses, which is consistent with previously published morphological and molecular studies.

RESUMEN

BACKGROUND AND PURPOSE: Endoscopic submucosal dissection (ESD) is a promising technique for superficial esophageal lesions. However, stricture is a frequent adverse complication. This study was performed to develop a precise and convenient score prediction model for esophageal strictures after ESD, and compare its efficacy with a previously published predictive model. METHODS: This study enrolled clinical data of patients who underwent esophageal ESD for superficial esophageal lesions. Possible risk factors for esophageal stricture were identified by univariate and multivariate logistic regression analysis. Then we developed a prediction model according to the Framingham system for the first time and presented a convenient table containing the risk probability for each patient. In addition, we validated our score model and the previously published model in our center. RESULTS: A total of 838 patients were enrolled in this study and 6 variables, including age, surgery time, location of the lesion, circumference of the lesion, longitudinal resection length, and depth of infiltration were comprised in the score model. The total score ranged from 0 to 16 points and the risk probability was presented in one concise table for each patient. Areas under receiver-operator characteristic curves for the prediction model were 0.715 in derivation group and 0.804 in validation group. CONCLUSION: We designed and validated a prediction score model for esophageal stricture after ESD, which can be applied conveniently to stratify the stricture risk after esophageal ESD and may facilitate appropriate clinical decision-making for these patients.

RESUMEN

Digital media can spread data and information. Its wide use not only enriches people's work and life but also brings high efficiency and convenience. However, due to different devices, different data quality, network stability, and other reasons, data quality is usually difficult to guarantee, so it is necessary to evaluate its perceptual integrity. In this paper, the group intelligence sensing technology in the sensor field and AWTC-TT optimization algorithm integrating blockchain technology are proposed to collect users' sensing data and build a model to discuss the complete performance. The experimental results show that (1) for the AWTC-TT algorithm, the processing time of 200 data tasks is less than 60 s; moreover, after optimization, the performance is efficient, which can effectively reduce the running time of data processing, and the performance loss is only 4%. (2) The perceptual quality of data was evaluated, the gain value of the first 0.4 is above 0.3, and the interference of abnormal data on integrity was explored. (3) The test results of the four integrality indexes of the model are good and the quality is stable. (4) The income value of CS2 is 5.8, and the income of distribution with the highest quality is the highest. Finally, the model constructed in this paper is mature, the experimental data and results are good, and the data perception integrity is discussed. The use of various fusion technologies can provide a reference for more subsequent research and application and lay a solid foundation.

RESUMEN

OBJECTIVE: To investigate the effect of transverse wrist crease perforator flap repair on sensory nerve function, survival of flap, hand function, hand appearance and satisfaction rate in patients with soft tissue defect of fingers. METHODS: This retrospective study was performed in 30 patients admitted to the Hand and Foot Microsurgery Department of our hospital between January 2018 and December 2020. These patients were divided into to the control group and the experimental group (15 patients for each group) according to the operative methods. Patients in the control group underwent abdominal flap repair, while patients in the experimental group received transverse wrist crease perforator flap repair. Intraoperative parameters, sensory nerve function, function of finger reconstruction, survival rate of skin flap, degree of scar contracture and flap bloatedness, DASH score, two-point discrimination and satisfaction rate were compared between the two groups. RESULTS: Compared with the control group, the operative time in the experiment group was obviously decreased (P<0.05). There was no difference in amount of bleeding between the two groups. The proportion of sensory nerve function grade S3+ and S4 in the experimental group was significantly increased in contrast to the control group (P<0.05). The total excellent and good rate in function of finger reconstruction in the experiment group was significantly higher than that in the control group, while no difference was found in the survival rate of skin flap and scar contracture between the two groups. Compared with the control group, DASH score, two-point discrimination distance, and degree of flap bloatedness in the experiment group were significantly reduced and the patients' satisfaction rate in the experiment group was remarkably increased (all P<0.05). CONCLUSION: Transverse wrist crease perforator flap repair plays a critical role in reducing operative time, improving sensory nerve function and recovery of hand function, and alleviating flap bloatedness. It is an optimal treatment for soft tissues defect of fingers.

RESUMEN

The raphidiopteran fauna of Xinjiang in northwestern China is poorly known, although it is near Central Asia where the diversity of this group is high. Herein we report a new species and a new Chinese record of the raphidiid genus Mongoloraphidia H. Aspck U. Aspck, 1968 from Xinjiang, namely Mongoloraphidia xinjiangana sp. nov. and Mongoloraphidia (Mongoloraphidia) kaszabi (H. Aspck U. Aspck, 1967), respectively. A key to the identification of the Mongoloraphidia species from China is provided.
