RESUMO

Asparaginase-associated pancreatitis (AAP) is a severe and potentially life-threatening drug-induced pancreas targeted toxicity in the combined chemotherapy of acute lymphoblastic leukemia among children and adolescents. The toxicological mechanism of AAP is not yet clear, and there are no effective preventive and treatment measures available clinically. Fibroblast growth factor 21 (FGF21) is a secretory hormone that regulates lipid, glucose, and energy metabolism balance. Acinar tissue is the main source of pancreatic FGF21 protein and plays an important role in maintaining pancreatic metabolic balance. In this study, we found that the decrease of FGF21 in pancreas is closely related to AAP. Pegaspargase (1 IU/g) induces widespread edema and inflammatory infiltration in the pancreas of rats/mice. The specific expression of FGF21 in the acinar tissue of AAP rats was significantly downregulated. Asparaginase caused dysregulation of the ATF4/ATF3/FGF21 axis in acinar tissue or cells, and thus mediated the decrease of FGF21. It greatly activated ATF3 in the acinar, which competed with ATF4 for the Fgf21 promoter, thereby inhibiting the expression of FGF21. Pharmacological replacement of FGF21 (1 mg/kg) or PERK inhibitors (GSK2656157, 25 mg/kg) can significantly mitigate the pancreatic tissue damage and reduce markers of inflammation associated with AAP, representing potential strategies for the prevention and treatment of AAP.

RESUMO

The topological phase transitions (TPT) of light refers to a topological evolution from one type of spin-orbit interaction to another, which has been recently found in beam scattering at optical interfaces and propagation in uniaxial crystals. In this work, the focusing of off-axis and partially masked circular-polarization Gaussian beams are investigated by using of a full-wave theory. Moreover, two different types of spin-orbit interactions (i.e., spin-dependent vortex generation and photonic spin-Hall effect) in the focusing system are unified from the perspective of TPT. It is demonstrated that as the off-axis distance or the masked area increases, a TPT phenomenon in the focused optical field takes place, evolving from the spin-dependent vortex generation to the spin-Hall shift of the beam centroids. The intrinsic mechanism is attributed to the cylindrical symmetry-breaking of the system. This symmetry-breaking induced TPT based on the method of vortex mode decomposition is further examined. The main difference between the TPT phenomenon observed here and that trigged by oblique incidence at optical interfaces or oblique propagation in uniaxial crystals is also uncovered. Our findings provide fruitful insights for understanding the spin-orbit interactions in optics, providing an opportunity for unifying the TPT phenomena in various spin-orbit photonics systems.

RESUMO

We employ a full-wave theory to systematically investigate two types of spin-orbit interactions and their topological phase transitions for various light beams (e.g., Laguerre-Gaussian, Bessel, and Bessel-Gaussian beams) at optical interfaces, and explore the influence of beam parameters on the spin-Hall shift. It is demonstrated that at small-angle incidence, the beam profile and spin-Hall shift are significantly affected by the beam parameters (e.g., waist radius, radial index, azimuthal index, and cone angle), whereas at large-angle incidence, only the azimuthal index has a salient influence on them. We further find that the Bessel beam and the Gaussian-modulated ones (i.e., Laguerre-Gaussian and Bessel-Gaussian beams) have similar topological phase transition phenomena but different shifts. Quantitative dependences of beam parameters, such as waist radius, radial index, azimuthal index, and cone angle, on the shift are also presented. Our findings offer alternative degrees of freedom in controlling the topological phase transitions of light, and suggest a valuable insight for exploring the applications of SOIs of diverse light fields.

RESUMO

Knowledge distillation (KD) is a well-established technique for compressing neural networks and has gained increasing attention in object detection tasks. However, typical object detection distillation methods use fixed-level semantic features for distillation, which might not be best for all training stages and samples. In this paper, a multilayer semantic feature adaptive distillation (MSFAD) method is proposed that uses a routing network composed of a teacher and a student detector, along with an agent network for decision making. Specifically, the inputs to the proxy network consist of the features output by the neck structures of the teacher and student detectors, and the output is a decision on which features to choose for distillation. The MSFAD method improves the distillation training process by enabling the student detector to automatically select valuable semantic-level features from the teacher detector. Experimental results demonstrated that the proposed method increased the mAP50 of YOLOv5s by 3.4% and the mAP50-90 by 3.3%. Additionally, YOLOv5n with only 1.9 M parameters achieved detection performance comparable to that of YOLOv5s.

RESUMO

BACKGROUND: Metal screws are the most widely used in treating syndesmotic injuries, but failure and the rigidity of the screws can threaten the success of the treatment and increase the cost of care. We have provided an alternative with an olive wire and external fixator(OWEF) used for syndesmotic fixation. METHODS: A retrospective longitudinal follow-up study was conducted. From February 2011 to January 2018, 58 of 72 patients with ankle fractures and associated syndesmotic disruption were treated with either screw or OWEF fixation. The costs, complications, and clinical outcomes using Olerud-Molander score and Visual Analog score in screw and OWEF fixation group were compared. RESULTS: We found the severity of the injury, BMI of the patients and the different fixation methods were determinants of the complications and clinical outcomes. But if no malreduction of the syndesmosis was present, no difference in clinical result was detected. CONCLUSION: The OWEF method appeared to be at least equally functional and effective to screw fixation while maintaining possible lower complication rate. LEVELS OF CLINICAL EVIDENCE: Level 3.

RESUMO

The current study aimed to establish simple and quick quality evaluation method of Chishao based on QAMS. Oxypaeoniflorin is used as a marker in the Chishao root. Based on it, the content of other components could be obtained by establishing the mathematical relationship. UPLC method was used to collect data, and the detection wavelengths were 230nm (benzoic acid, paeoniflorin), 263nm (hydroxy paeoniflorin) 274nm (gallic acid, paeoniflorin, catechin), respectively. The stationary phase was an Agilent ZORBAX SB-C18 and the mobile phase was acetonitrile -0.1% formic acid-water. The gradient elution method was adopted at the certain flow rate (0.3 mL/min). The column temperature set 40oC, and the injection volume was 1µL. Multiple reaction monitoring mode was selected for data collection. The linear ranges of benzoic acid, paeoniflorin, hydroxy-paeoniflorin, gallic acid, catechin and paeoniflorinhad good linearity (r ≥0.9995). The UPLC method was established to determine the content of paeoniflorin, benzoic acid, catechin, gallic acid, paeoniflorin, andhydroxy-paeoniflorin in Radix Paeoniae Rubra. In the current study, the method for the chemical components in Radix Paeoniae Rubra to provide the evaluation basis of medicinal effects.

RESUMO

This study investigated the association of genotype (CGG repeats in FMR1) and the health and well-being of 5,628 aging adults (mean age = 71) in a population-based study. Two groups were contrasted: aging parents who had adult children with developmental or mental health disabilities (n = 785; the high-stress parenting group) and aging parents of healthy children who did not have disabilities (n = 4843; the low-stress parenting group). There were significant curvilinear interaction effects between parenting stress group and CGG repeats for body mass index and indicators of health and functional limitations, and the results were suggestive of interactions for limitations in cognitive functioning. Parents who had adult children with disabilities and whose genotype was two standard deviations above or below the mean numbers of CGGs had poorer health and functional outcomes at age 71 than parents with average numbers of CGGs. In contrast, parents who had healthy adult children and who had similarly high or low numbers of CGG repeats had better health and functional outcomes than parents with average numbers of CGGs. This pattern of gene by environment interactions was consistent with differential susceptibility or the flip-flop phenomenon. This study illustrates how research that begins with a rare genetic condition (such as fragile X syndrome) can lead to insights about the general population and contributes to understanding of how genetic differences shape the way people respond to environments. © 2017 Wiley Periodicals, Inc.

RESUMO

PURPOSE: Meta-analysis was conducted to estimate whether MiTLIF could reduce the complication rate while maintaining the similar clinical result to that of open procedures. METHODS: A search of the literature was conducted on pubmed or EMBASE. A database including patient clinical information was created. A systematic review of eligible studies with multivariate regression analysis was performed to quantitatively review the correlation of VAS improvement rate and the performance of MiTLIF. RESULTS: Fourteen articles with a minimum of 12-month follow-up met our inclusion criteria. The hypothesis of homogeneity could be accepted. The fixed-effects model was used to calculate the summary risk ratio (odds ratio). In the pooled analysis, the summary risk ratio (odds ratio) in patients with MiTLIF against those with open procedure for fusion rate, complication rate and revision/readmission rate was 0.99 (p = 0.36), 1.15 (p = 0.5) and 2.59 (p = 0.003), respectively, suggesting that MiTLIF was a risk factor for revision/readmission. Multivariate regression analysis showed that the percentage of male patients and the length of surgery exert a significant impact on VAS improvement rate. The selection of MiTLF was not significant. CONCLUSION: Fusion rate and complication rate for both open and MiTLIF were similar. Moreover, the MiTLIF group tended to have a higher revision/readmission rate, which might be associated with the deep learning curve. Therefore, to achieve the level of surgical skill required of an MiTLIF surgeon, many years of training and experience are necessary. Otherwise, MiTLIF may yield unsatisfactory result upon patients.

RESUMO

OBJECTIVE: Chronic post surgical pain (CPSP) occurres frequently (from 10% to 50%) and has serious effects on the mood and activities of patients. This study was designed to evaluate the relationship between acute post surgical pain and chronic post surgical pain. METHODS: Electronic search databases included PubMed, EMBASE, Cochrane database and web of science. 9-stars Newcastle-Ottawa Scale was used to evaluate the quality of included studies. The odds ratio was used as a summary statistic index. Heterogeneity was assessed with I (2). RESULTS: We collected data from 4 case-control studies with or without chronic post surgical pain and compared those with patients who had acute post surgical pain or not. The age, sex was controlled as confounding factors. We collected 765 patients with chronic post surgical pain, of which 38.82% used to have acute post surgical pain. The risk ratio of patients with acute post surgical pain, as compared with no acute post surgical pain, was 3.10 for chronic post surgical pain (95% CI: 2.44, 3.96). CONCLUSION: Acute post surgical pain is a rick factor for chronic post surgical pain. We need to pay much attention to this phenomenon. However, more studies with high quality were still needed to confirm these findings.

RESUMO

Objective: To analyze the menstrual characteristics of endometrial carcinoma and investigate whether abnormal uterine bleeding in the perimenopausal period differs from postmenopausal bleeding. Methods: We conducted a retrospective analysis of 928 cases of endometrial carcinoma in patients admitted from January 2016 to December 2022. We gathered fundamental clinical data and analyzed distinct clinical risk factors between the perimenopausal and postmenopausal groups. Furthermore, we computed the statistical variances in menarche, regular menstrual cycles, and the duration of abnormal uterine bleeding. Results: Perimenopausal patients with endometrial carcinoma exhibit similar factors to postmenopausal patients, especially if they have a history of menstrual cycles lasting more than 30 years, hypertension, abnormal uterine bleeding for over 1 year, and a high risk of endometrial carcinoma. Early intervention for abnormal uterine bleeding during the perimenopausal stage can prevent up to 80% of women from developing endometrial carcinoma. Conclusion: Perimenopause women experiencing abnormal uterine bleeding should be mindful of the risk of endometrial carcinoma, as this awareness can substantially decrease the occurrence of the disease.

RESUMO

Phenotypic screening is a valuable tool to both understand and engineer complex biological systems. We demonstrate the functionality of this approach in the development of cell-free protein synthesis (CFPS) technology. Phenotypic screening identified numerous compounds that enhanced protein production in yeast lysate CFPS reactions. Notably, many of these were competitive ATP kinase inhibitors, with the exploitation of their inherent substrate promiscuity redirecting ATP flux towards heterologous protein expression. Chemoproteomic-guided strain engineering partially phenocopied drug effects, with a 30% increase in protein yield observed upon deletion of the ATP-consuming SSA1 component of the HSP70 chaperone. Moreover, drug-mediated metabolic rewiring coupled with template optimization generated the highest protein yields in yeast CFPS to date using a hitherto less efficient, but more cost-effective glucose energy regeneration system. Our approach highlights the utility of target-agnostic phenotypic screening and target identification to deconvolute cell-lysate complexity, adding to the expanding repertoire of strategies for improving CFPS.

RESUMO

Despite the improved survival rate among systemic lupus erythematosus (SLE) patients, there are many factors associated with the mortality of SLE. In the current study, death-related factors of patients associated with course of disease were surveyed. Retrospective study was used. Mortalities among these three groups (group A, B and C, the course of disease was ≤ 5 years, 5-10 years and > 10 years, respectively) were calculated and compared. Various factors related to mortality were analyzed. Male SLE patients died relatively more than female patients. The total mortality was 8.5 %. The mortalities were significant difference in group A, B and C which were 9.4, 4.8 and 8.9 %, respectively. The mortalities of group A and group C were significantly higher than that of group B, but there was no significant difference between mortalities of group A and group C. The most common death-related factor was infection, followed by involved disorders in renal, brain, multisystem, heart, etc. The mortalities resulted from neuropsychiatric systemic lupus erythematosus (NPSLE), pulmonary infection, involved digestive system and hematological system were significantly different between three groups. There was no difference between mortalities of group A and group C associated with pulmonary infection and NPSLE. Patients in group C died more than in group A from involved renal, heart, multisystem, etc, while group A had more patients than group C who died of pulmonary infection, involved hematological system. In conclusion, Male SLE patients have worse outcome than female patients. Infection and active SLE are not only contributors to the death of early stage patients, but also to that of later stage patients.

RESUMO

Variation in the FMR1 gene may affect aspects of cognition, such as executive function and memory. Environmental factors, such as stress, may also negatively impact cognitive functioning. Participants included 1,053 mothers of children with and without developmental disabilities. Participants completed self-report measures of executive function, memory, and stress (i.e., life events, parenting status), and provided DNA to determine CGG repeat length (ranging from 7 to 192 CGGs). Stress exposure significantly predicted greater self-reported difficulties in executive function and the likelihood of memory problems. Cubic CGG effects independently predicted executive function and memory difficulties, suggesting effects of both genetic variation and environmental stress exposure on cognitive functioning.

RESUMO

Higher education has been shown to have neuroprotective effects, reducing the risk of Alzheimer's and Parkinson's diseases, slowing the rate of age-related cognitive decline, and is associated with lower rates of early mortality. In the present study, the association between higher education, fragile X messenger ribonucleoprotein 1 (FMR1) cytosine-guanine-guanine (CGG) repeat number, and mortality before life expectancy was investigated in a population cohort of women born in 1939. The findings revealed a significant interaction between years of higher education and CGG repeat number. Counter to the study's hypothesis, the effects of higher education became more pronounced as the number of CGG repeats increased. There was no effect of years of higher education on early mortality for women who had 25 repeats, while each year of higher education decreased the hazard of early mortality by 8% for women who had 30 repeats. For women with 41 repeats, the hazard was decreased by 14% for each additional year of higher education. The interaction remained significant after controlling for IQ and family socioeconomic status (SES) measured during high school, as well as factors measured during adulthood (family, psychosocial, health, and financial factors). The results are interpreted in the context of differential sensitivity to the environment, a conceptualization that posits that some people are more reactive to both negative and positive environmental conditions. Expansions in CGG repeats have been shown in previous FMR1 research to manifest such a differential sensitivity pattern.

RESUMO

BACKGROUND/AIMS: Mucosa-associated T-lymphocyte (MAIT) cells that are selectively accumulated in the intestinal mucosa may be involved in immune regulation. MAIT cells are determined by their Vα7.2-Jα33 (human)/Vα19-Jα33 (mice) invariant chain. The encoding DNA sequences of Human Jα33 and mouse Jα33 are identical. In order to study the role of MAIT cells in IBD we produced anti-Jα33 antibody to detect MAIT cells in TNBS induced IBD models. METHODOLOGY: Colitis was induced by TNBS in male BALB/c mice. Jα33+MAIT cells from normal mice were transferred into TNBS induced mice as donors. Colitis severity was evaluated clinically and histologically, under the condition of transferred Jα33+MAIT cells. RESULTS: The mRNA and protein expression levels of MAIT aTCR in the colonic mucosa were decreased after TNBS administration; Jα33+MAIT cells were aggregated in spleen after TNBS administration. The disease activity index (DAI) which was determined by weight loss, stool consistency and intestinal bleeding, increased after TNBS administration. Transferred Jα33+MAIT cells significantly degrade the increase in the disease activity index scores. CONCLUSIONS: Taken together, the results indicated that the aggregation of Jα33+MAIT cells in intestinal mucosa improved TNBS-induced colitis. We conclude that Jα33+MAIT cells play a protective role in TNBS induced intestinal inflammation.

RESUMO

The primary goal of this study was to calculate the prevalence of the premutation of the FMR1 gene and of the "gray zone" using a population-based sample of older adults in Wisconsin (n = 6,747 samples screened). Compared with past research, prevalence was relatively high (1 in 151 females and 1 in 468 males for the premutation and 1 in 35 females and 1 in 42 males for the gray zone as defined by 45-54 CGG repeats). A secondary study goal was to describe characteristics of individuals found to have the premutation (n = 30, 7 males and 23 females). We found that premutation carriers had a significantly higher rate of divorce than controls, as well as higher rates of symptoms that might be indicative of fragile X-associated tremor ataxia syndrome (FXTAS; numbness, dizziness/faintness) and fragile X primary ovarian insufficiency (FXPOI; age at last menstrual period). Although not statistically significant, premutation carriers were twice as likely to have a child with disability.

RESUMO

The prognosis of various cardiovascular diseases eventually leads to heart failure (HF). An energy metabolism disorder of cardiomyocytes is important in explaining the molecular basis of HF; this will aid global research regarding treatment options for HF from the perspective of myocardial metabolism. There are many drugs to improve myocardial metabolism for the treatment of HF, including angiotensin receptor blocker-neprilysin inhibitor (ARNi) and sodium glucose cotransporter 2 (SGLT-2) inhibitors. Although Western medicine has made considerable progress in HF therapy, the morbidity and mortality of the disease remain high. Therefore, HF has attracted attention from researchers worldwide. In recent years, the application of traditional Chinese medicine (TCM) in HF treatment has been gradually accepted, and many studies have investigated the mechanism whereby TCM improves myocardial metabolism; the TCMs studied include Danshen yin, Fufang Danshen dripping pill, and Shenmai injection. This enables the clinical application of TCM in the treatment of HF by improving myocardial metabolism. We systematically reviewed the efficacy of TCM for improving myocardial metabolism during HF as well as the pharmacological effects of active TCM ingredients on the cardiovascular system and the potential mechanisms underlying their ability to improve myocardial metabolism. The results indicate that TCM may serve as a complementary and alternative approach for the prevention of HF. However, further rigorously designed randomized controlled trials are warranted to assess the effect of TCM on long-term hard endpoints in patients with cardiovascular disease.

RESUMO

OBJECTIVE: To investigate the new genetic variations of regulator of G-protein signalling 2 (RGS2) gene in Kazakh hypertensives. METHODS: Totally 94 Kazakh patients with essential hypertension were enrolled and genomic DNA was extracted from their peripheral blood leukocytes. All the exon regions and their flanking sequences of RGS2 were directly sequenced. RESULTS: We identified 13 variants including 5 common- single nucleotide polymorphisms with a minor allele frequency over 5%single nucleotide polymorphisms and 8 novel variations in 94 Kazakh hypertensives. Among these variations, 2 were in the introns and 7 in the promoter region. One subject had a G-to-C substitution at nucleotide 54 in exon 1, which lead to an amino acid substitution from K-to-N at position 18; another individual had an A-to-G substitution at nucleotide 2422 in exon 5, resulting in an amino acid from Y-to-C at position 178. Among eight common single nucleotide polymorphisms, -638A>G, -395G>C, 1891-1892TC I/D, and 2971G>C,and -43A>T and 2297A>G were in tight linkage disequilibrium with an r-square of more than 0.8, respectively. CONCLUSIONS: The variants and their frequencies in RGS2 gene in Kazakh hypertensives may have ethnic differences when compared with other populations. The frequencies of the mutations are low in this population, and whether they influence blood pressure regulation requires further functional experiments.

RESUMO

FMR1 CGG repeat length was assayed in 5499 research participants (2637 men and 2862 women) in the Wisconsin Longitudinal Study (WLS), a population-based cohort. Most past research has focused on clinically-ascertained individuals with expansions in CGG repeats, either those with fragile X syndrome (> 200 CGG repeats), the FMR1 premutation (55-200 repeats), or in the gray zone (variously defined as 45-54 or 41-54 repeats). In contrast, the WLS is a unique source of data that was obtained from an unselected cohort of individuals from the general population for whom FMR1 CGG repeat length was assayed. The WLS is a random sample of one-third of all high school seniors in the state of Wisconsin in 1957. The most recent round of data collection was in 2011; thus, the study spanned over 50 years. Saliva samples were obtained from 69% of surviving members of the cohort in 2008 and 2011, from which CGG repeats were assayed. With one exception, the CGG repeat length of all members of this cohort was below 100 (ranging from 7 to 84). The present study evaluated the genotype-phenotype associations of CGG repeat number and IQ, college graduation, age at menopause, number of biological children, having a child with intellectual or developmental disabilities, and the likelihood of experiencing an episode of depression during adulthood. Linear and curvilinear effects were probed. Although effect sizes were small, significant associations were found between CGG repeat length and high school IQ score, college graduation, number of biological children, age at menopause, and the likelihood of having an episode of depression. However, there was no significant association between repeat length and having a child diagnosed with an IDD condition. This study demonstrates a continuum of phenotype effects with FMR1 repeat lengths and illustrates how research inspired by a rare genetic condition (such as fragile X syndrome) can be used to probe genotype-phenotype associations in the general population.

RESUMO

PURPOSE: The aim of the research was to evaluate the efficacy and safety associated with Fuke Qianjin tablet combined with conventional therapy in the treatment of pelvic inflammatory diseases and associated complications (endometritis) using a meta-analysis approach. Patients and Methods. We searched 8 electronic databases up to December 31, 2019, including PubMed, the Cochrane Library, Embase, Web of Science, CNKI, WanFang, VIP, and SinoMed. Eligible studies were clinical trials of Fuke Qianjin tablet combined with conventional therapy used in the treatment of acute pelvic inflammatory disease, chronic pelvic inflammatory disease, and endometritis. The meta-analysis was performed using STATA15 software. RESULTS: A total of 125 RCTs (n = 14,494) were shortlisted for the meta-analysis, which included 23 trials for acute pelvic inflammatory disease, 69 trials for chronic pelvic inflammatory disease, and 33 trials for endometritis. The overall analysis illustrated Fuke Qianjin tablet combined with conventional therapy was significantly more efficacious than conventional therapy alone across all types of antibiotics treatment for acute pelvic inflammatory disease (OR = 5.57, 95% CI 4.09-7.58, Z = 10.90, p=0.001), chronic pelvic inflammatory disease (OR = 4.70, 95% CI 4.07-5.42, Z = 21.21, p=0.001) and endometritis (OR = 5.09, 95% CI 4.03-6.43; Z = 13.63, p=0.001) in both primary endpoints and secondary endpoints. There is also a trend that Fuke Qianjin tablet combined with conventional therapy has lower adverse reaction rates than conventional therapy alone. CONCLUSION: Fuke Qianjin tablet combined with conventional therapy showed better clinical efficacy in the treatment of acute pelvic inflammatory disease, chronic pelvic inflammatory disease, and endometritis. There were no obvious drug-related adverse reactions. Fuke Qianjin tablet presented advantages in shortening the remission time of clinical symptoms, reducing the concentration of serum inflammatory factors, improving endometrial thickness, menstruation, and reducing relapse rate.
