Association Between Daily Executive Function and Core Symptoms， Attention Deficit-Hyperactivity Symptoms in Children with Autism Spectrum Disorder / 中山大学学报(医学科学版)

ObjectiveTo explore the association between daily executive function and core symptoms， the symptoms of attention deficit hyperactivity disorder （ADHD） in children with autism spectrum disorder （ASD）， and the moderating effect of theory of mind and other cognitive abilities on this association. MethodsChildren aged 6-12 years with ASD were recruited， and 86 children were identified according to the inclusion and exclusion criteria. Wechsler Intelligence Test for Children， Fourth Edition （WISC-Ⅳ）， Strange Story Test （SST） and Behavior Rating Inventory of Executive Function （BRIEF） were used to evaluate children's cognitive ability. Swanson Nolan and Pelham-Version Ⅳ Scale （SNAP-Ⅳ）， Social Responsiveness Scale （SRS）， and Repetitive Behavior Scale-Revise （RBS-R） were used to assess the severity of ADHD symptoms， social impairment， and repetitive stereotyped behavior. Multiple linear regression was used to explore the association between daily executive function and ADHD symptoms， social impairment， repetitive stereotyped behaviors. ResultsAfter controlling for the score of strange stories， verbal comprehension index （VCI） and other factors， the full scale score and each index of BRIEF were positively correlated with full scale score of SNAP （b = 0.619-0.741， b’ = 0.637-0.755）， SRS （b = 0.928-1.200， b’ = 0.417-0.513） and RBS-R （b = 0.326-0.525， b’ = 0.339-0.520） in children with ASD （P< 0.05）， and the SNAP total score was more strongly correlated with the full scale BRIEF score and each index score （b’ = 0.637-0.755，P< 0.01）. In addition to daily executive function， strange stories score （b = -2.218- -1.839） and age （b = 3.181-4.037） were also the important factors affecting the social function of children with ASD （P< 0.01）. There were no moderating effects of strange stories score and age on the association between BRIEF score and full scale score of SNAP， SRS， and RBS-R（P> 0.05）. ConclusionThe deficits of daily executive function in school-aged ASD children are significantly associated with core symptoms and ADHD symptoms， and the association is independent of other cognitive domains， such as theory of mind and verbal comprehension intelligence quotient.

ZHANG Wei-hua's clinical experience of Zhenjing Anshen method in treatment of insomnia / 中国针灸

The paper summarizes professor ZHANG Wei-hua's clinical experience in treatment of insomnia with Zhenjing Anshen (calming-down the spirit) method. It is believed that insomnia results from the unstable spirit in pathogenesis of TCM. The basic therapeutic principle is regulating the spirit, in which, stabilizing the primary spirit and tranquilizing the heart spirit are emphasized. Main acupoints are Baihui (GV 20), Sishencong (EX-HN 1) and Yintang (GV 24+) to stabilize the primary spirit, located on the head; and Shenmen (HT 7) located on the wrist to calm-down the heart spirit, as well as Sanyinjiao (SP 6) and Yongquan (KI 1) in the lower extremities to benefit yin and balance yang, and then to house the spirit eventually. The needles are inserted in different depths and to various directions. The external application of herbal plaster is combined at Yongquan (KI 1) and the supplementary acupoints are selected in terms of syndrome differentiation. This therapy is simple in acupoint selection and very effective in treatment of insomnia.

Random sperm DNA fragmentation index is not associated with clinical outcomes in day-3 frozen embryo transfer / 亚洲男科学杂志(英文版)

Damage to sperm DNA was proposed to play an important role in embryonic development. Previous studies focused on outcomes after fresh embryo transfer, whereas this study investigated the influence of sperm DNA fragmentation index (DFI) on laboratory and clinical outcomes after frozen embryo transfer (FET). This retrospective study examined 381 couples using cleavage-stage FET. Sperm used for intracytoplasmic sperm injection (ICSI) or in vitro fertilization (IVF) underwent density gradient centrifugation and swim up processing. Sperm DFI had a negative correlation with sperm motility (r = -0.640, P < 0.01), sperm concentration (r = -0.289, P < 0.01), and fertilization rate of IVF cycles (r = -0.247, P < 0.01). Sperm DFI examined before and after density gradient centrifugation/swim up processing was markedly decreased after processing (17.1% vs 2.4%, P < 0.01; 65 randomly picked couples). Sperm progressive motility was significantly reduced in high DFI group compared with low DFI group for both IVF and ICSI (IVF: 46.9% ± 12.4% vs 38.5% ± 12.6%, respectively; ICSI: 37.6% ± 14.1% vs 22.3% ± 17.8%, respectively; both P < 0.01). The fertilization rate was significantly lower in high ( ≥25%) DFI group compared with low (<25%) DFI group using IVF (73.3% ± 23.9% vs 53.2% ± 33.6%, respectively; P < 0.01) but was equivalent in high and low DFI groups using ICSI. Embryonic development and clinical outcomes after FET were equivalent for low and high DFI groups using ICSI or IVF. In this study, sperm DFI did not provide sufficient information regarding embryo development or clinical outcomes for infertile couples using FET.

Application of "kindergarten effect" in radiotherapy for children with tumor aged 3-5 years / 中国当代儿科杂志

OBJECTIVES@#To study the clinical application effect of "kindergarten effect" in radiotherapy for children with tumor based on the psychology of preschool children aged 3-5 years.@*METHODS@#A total of 30 children, aged 3-5 years, who were admitted to the Department of Radiotherapy, Tianjin Medical University Cancer Institute and Hospital, from January 2020 to August 2021 were enrolled in this prospective study. The children were randomly divided into a control group and a test group, with 15 children in each group. The children in the test group were treated in "kindergarten mode", i.e., all children were treated together at a specified time and left together after all children completed treatment. Those in the control group were treated alternately with adult patients according to the treatment time based on the type of radiotherapy fixation device. The treatment compliance was evaluated for both groups, and the two groups were compared in terms of the setup errors in the superior-inferior (SI), left-right (LR), and anterior-posterior (AP) directions.@*RESULTS@#Compared with the control group, the test group showed a significantly shorter time for finishing the treatment (P<0.05) and a significantly lower proportion of children with treatment interruption (P<0.05). Compared with the control group, the test group showed smaller mean errors in the SI, LR and AP directions after image-guided radiotherapy, with significant differences in the mean errors in the SI and LR directions (P<0.05).@*CONCLUSIONS@#With the application of the "kindergarten effect", most children can actively cooperate in radiotherapy, and it can also improve the accuracy and repeatability of positioning and help to achieve the desired treatment outcome.

Introduction of a tool to assess Risk of Bias in Non-randomized Studies-of Environmental Exposure (ROBINS-E) / 中华流行病学杂志

This paper summaries the Risk of Bias in Non-randomized Studies-of Environmental Exposure (ROBINS-E), a tool for evaluating risk of bias about non-randomized studies of exposures (NRSE), and introduces the application of ROBINS-E in a published NRSE. According to the characteristics of NRSE, evaluation fields and signaling questions were designed in ROBINS-E to provide essential information about risk of bias for NRSE included in systematic reviews and GRADE. ROBINS-E is the tool in assessment of risk of bias in observational studies and quasi-randomized studies. Although the tool has been used in practice to some extent, but it still needs further improvement. Attention should be paid to its update and progress.

Study on the influencing factors in pupils' disequilibrium refractive development / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the influencing factors of disequilibrium refractive development in children aged 6-12 years old.METHODS: A total of 607 children with a mean age of 8.2±1.8 years old from two primary schools in Binhai New Area of Tianjin in December 2019 were selected by cluster sampling for optical biometry measurement(axial length and equivalent corneal power), cycloplegia refractive examination and questionnaire survey.RESULTS: The childrens'spherical equivalent was -0.11±1.63D, binocular spherical equivalent difference was -0.08±0.64D and absolute value of spherical equivalent difference was 0.41±0.49D. There were 56 children with anisometropia and 551 children without anisometropia. There was no difference in the absolute value of binocular corneal power difference between anisometropia and non-anisometropia group(0.30±0.34D vs 0.27±0.24D, P=0.430). But the absolute value of axial difference was significantly different(0.67±0.39mm vs 0.13±0.13mm, P=0.005). Multivariate linear regression analysis showed that weekly usage time of phones/computers, weekly close work hours, weekly visual fatigue times and habitual reading distance were the influencing factors of refractive imbalance development(the absolute value of binocular spherical equivalent difference). Habitual reading distance and handedness in writing are the influencing factors of the developmental bias of refractive imbalance(binocular spherical equivalent difference).CONCLUSION: Children aged 6-12 years old who spend more time on phones/computers, and have prolonged close work, more times of visual fatigue and close habitual reading distance may increase the degree of refractive imbalance. Children with right-handed handwriting and severe left or right head deviation have a deeper degree of myopia in the right eye than in the left eye.

Tenuifolin in Treatment of Dementia： A Review / 中国实验方剂学杂志

Tenuifolin， a main component in Polygalae Radix， is frequently used as an important indicator for quality control of Polygalae Radix and its processed products. Dementia is a serious and persistent cognitive disorder， and the number of dementia patients is increasing worldwide， which brings great economic burden and mental pressure to families and society. At present， cholinesterase inhibitor and other drugs can only alleviate the symptoms of dementia， and there are some toxic and side effects. It has been found that tenuifolin can significantly improve cognitive disorder， learning and memory and is expected to be a potential drug for treating dementia. Tenuifolin exerts protective effects on amyloid-β （Aβ） deposition， acetylcholine reduction， neuroinflammation， cellular oxidative damage and nerve cell apoptosis caused by neurodegenerative diseases via multiple mechanisms， and can be applied to various types of dementia. In addition， it can be quickly absorbed into the blood， mainly distributed in liver and kidney， and can enter into the brain through the blood-brain barrier. However， because of its large molecular mass and poor fat solubility， tenuifolin can be rapidly eliminated， generating some problems such as low oral absoBrbability and permeability of blood-brain barrier. Therefore， the information of chemistry， pharmacology， pharmacokinetics and toxicology of tenuifolin was summarized in this paper to provide reference and ideas for further research and application.

The myocardial protective effect of propofol on rats with experimental myocardial infarction and its mechanism / 生理学报

The aim of the present study was to investigate the protective effect of propofol on the experimental myocardial infarction in rats. The myocardial infarction model was established by ligating the anterior descending branch of left coronary artery in rats. Model rats were treated with propofol. Cardiac function was evaluated by echocardiography. Cardiac hemodynamic changes were detected by multiconductor biorecorder. Pathological changes in the infarcted myocardia were detected by HE staining. The expression levels of cardiac hypertrophy marker genes and fibrosis marker proteins were analyzed by real-time quantitative PCR and Western blot. The results showed that, compared with the sham surgery group, the model group exhibited larger infarct size (> 40%), impaired heart function, and significantly increased left ventricular end-diastolic pressure (LVEDP). Propofol reduced cardiac function impairment and decreased LVEDP in the model group. Propofol significantly reduced lung weight/body weight ratio, heart weight/body weight ratio, left ventricular weight/body weight ratio and left atrial weight/body weight ratio in the model group. Furthermore, after myocardial infarction, the administration of propofol significantly improved the diastolic strain rate, down-regulated the mRNA expression levels of myocardial hypertrophy markers, atrial natriuretic peptide and β-myosin heavy chain, and reversed the up-regulation of matrix metalloproteinase 2 (MMP2), MMP9 and tissue inhibitor of metalloproteinase-2 (TIMP-2) induced by myocardial infarction. These results suggest propofol can reduce adverse ventricular remodeling, cardiac dysfunction, myocardial hypertrophy and fibrosis after myocardial infarction, and has protective effect against the experimental myocardial infarction induced by coronary artery ligation in rats.

Mutation analysis and phenotypic investigation in patients with primary distal renal tubular acidosis / 中华肾脏病杂志

Objective:To analyze the gene variants in patients with primary distal renal tubular acidosis (dRTA), and explore the correlation between the genotype and phenotype.Methods:The Sanger direct sequencing or whole-exome sequencing was used to identify causal variants and the variation pathogenicity was evaluated according to 2015 American College of Medical Genetics and Genomics (ACMG) standards and guidelines in 44 dRTA patients (37 families) diagnosed in the Affiliated Qingdao Municipal Hospital of Qingdao University and the Affiliated Hospital of Qingdao University from April 2010 to September 2020. The clinical features of the patients were summarized, and the correlation between the genotype and phenotype was investigated.Results:Seven variants of SLC4A1 gene, 17 variants of ATP6V0A4 gene, and 15 variants of ATP6V1B1 gene were identified in 44 patients with dRTA, and of which 11 variants were new ones. According to ACMG guidelines, the pathogenic, likely pathogenic, benign variants among the 39 variants were 22, 16 and 1, respectively. Nine patients were autosomal dominant hereditary dRTA caused by SLC4A1 gene mutation, 4 patients with autosomal recessive hereditary dRTA complicated with Southeast Asian ovalocytosis and anemia were caused by SLC4A1 gene mutation, and 14 patients caused by ATP6V0A4 gene mutation and 8 patients caused by ATP6V1B1 gene mutation were autosomal recessive hereditary dRTA; Two children with dRTA were found to carry one monoallelic defect in ATP6V1B1, and no causal gene mutation was identified in 7 patients. One patient showed incomplete dRTA, and the other 43 patients showed complete dRTA. The prevalence of sensory neural hearing loss caused by ATP6V0A4 and ATP6V1B1 mutation were 2/14 and 6/10 respectively. The frequency of chronic kidney disease in adults, children and infants were 4/4, 2/4, and 1/36, separately. After the drug treatment based on potassium citrate and sodium citrate, the growth and development (28/40) and electrolyte disturbance (41/44) of most patients were significantly improved. Conclusions:The present study has identified 39 variants of SLC4A1, ATP6V0A4 and ATP6V1B1 genes in 44 patients with dRTA, including 11 novel ones. There is a close relationship between genotype and phenotype in dRTA patients and most patients' conditions were improved after proper treatment. This study enriches the human gene mutation database and provides valuable references for diagnosis, treatment and genetic counseling in patients with dRTA.

Comparison of the efficacy between open and arthroscopic Latarjet procedure in the treatment of anterior shoulder instability:a Meta-analysis / 中国骨伤

OBJECTIVE@#To compare the clinical efficacy between open and arthroscopic Latarjet procedure in the treatment of anterior shoulder instability by using Meta-analysis.@*METHODS@#Search PubMed, Medline, Embase, Cochrane, China National Knowledge Infrastructure(CNKI), Wanfang database, China Biological Literature system(CBM) and VIP database. Review all retrospective or prospective cohort studies and randomized controlled trials on open and arthroscopic Latarjet procedure for anterior shoulder instability. Binary variables (postoperative recurrence rate, incidence of intraoperative and postoperative complications) and continuousvariables [shoulder external rotation range of motion, Walch-Duplay score, Rowe score, WOSI score, postoperative visual analogue scale (VAS), postoperative anxiety degree and operation time] were selected for analysis. NOS bias risk assessment criteria (recommended by Cochrane collaboration Network) were used to evaluate the literature quality of retrospective or prospective cohort studies, and modified Jadad scale was used to evaluate the quality of randomized controlled trials. Literature screening, literature quality evaluation and data extraction were carried out independently by two observers. RevMan 5.3 software was used for Meta analysis.@*RESULTS@#(1)A total of 9 studies were included, including 8 retrospective cohort studies and 1 prospective cohort study. A total of 956 patients were included in this study, including open Latarjet procedure(@*CONCLUSION@#The arthroscopic Latarjet stabilisation shows satisfactory and comparable results to open procedure, and the postoperative recurrence and complication rates are low in both group. Both open and arthroscopic Latarjet procedure are reliable surgical procedures in the treatment of anteriorly shoulder instability. Arthroscopic procedure has longer learning curve than open procedure, the doctors may either choose arthroscopic or open Latarjet procedure based on personal skills and preference, as well as the patient's condition. However, all the literatures included in this study are cohort studies with low level of evidence. The research lack randomized controlled trials, and small sample size is small. In the future, randomized controlled studies with large sample size and high level of evidence are still needed to determine the efficacy difference between the two.

Comparative effectiveness and safety of 32 pharmacological interventions recommended by guidelines for coronavirus disease 2019: a systematic review and network meta-analysis combining 66 trials / 中华医学杂志(英文版)

BACKGROUND@#The global pandemic coronavirus disease 2019 (COVID-19) has become a major public health problem and presents an unprecedented challenge. However, no specific drugs were currently proven. This study aimed to evaluate the comparative efficacy and safety of pharmacological interventions in patients with COVID-19.@*METHODS@#Medline, Embase, the Cochrane Library, and clinicaltrials.gov were searched for randomized controlled trials (RCTs) in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)/SARS-CoV. Random-effects network meta-analysis within the Bayesian framework was performed, followed by the Grading of Recommendations Assessment, Development, and Evaluation system assessing the quality of evidence. The primary outcome of interest includes mortality, cure, viral negative conversion, and overall adverse events (OAEs). Odds ratio (OR) with 95% confidence interval (CI) was calculated as the measure of effect size.@*RESULTS@#Sixty-six RCTs with 19,095 patients were included, involving standard of care (SOC), eight different antiviral agents, six different antibiotics, high and low dose chloroquine (CQ_HD, CQ_LD), traditional Chinese medicine (TCM), corticosteroids (COR), and other treatments. Compared with SOC, a significant reduction of mortality was observed for TCM (OR = 0.34, 95% CI: 0.20-0.56, moderate quality) and COR (OR = 0.84, 95% CI: 0.75-0.96, low quality) with improved cure rate (OR = 2.16, 95% CI: 1.60-2.91, low quality for TCM; OR = 1.17, 95% CI: 1.05-1.30, low quality for COR). However, an increased risk of mortality was found for CQ_HD vs. SOC (OR = 3.20, 95% CI: 1.18-8.73, low quality). TCM was associated with decreased risk of OAE (OR = 0.52, 95% CI: 0.38-0.70, very low quality) but CQ_HD (OR = 2.51, 95% CI: 1.20-5.24) and interferons (IFN) (OR = 2.69, 95% CI: 1.02-7.08) vs. SOC with very low quality were associated with an increased risk.@*CONCLUSIONS@#COR and TCM may reduce mortality and increase cure rate with no increased risk of OAEs compared with standard care. CQ_HD might increase the risk of mortality. CQ, IFN, and other antiviral agents could increase the risk of OAEs. The current evidence is generally uncertain with low-quality and further high-quality trials are needed.

Myelodysplastic syndrome in a 30-year-old man with coronavirus disease 2019 (COVID-19): a diagnostic challenge

Background Myelodysplastic syndromes (MDS) mainly occur in the elderly but can rarely affect younger individuals too. The correct diagnosis relies on careful morphologic evaluation, cytogenetic/molecular results, and excluding reactive conditions mimicking MDS. We present the clinical, pathologic, cytogenetic, and molecular features of a case of MDS with excess blasts-2 (MDS-EB-2) in a 30-year-old male who was found to have pancytopenia during his hospitalization for coronavirus disease 2019 (COVID-19) and discuss the diagnostic challenges of MDS in patients with COVID-19. Case presentation A 30-year-old man presented to an outside hospital with fever, chills, weakness, coughing spells, dizziness and shortness of breath and was diagnosed with bilateral pneumonia due to COVID-19. At the outside hospital, he was found to be pancytopenic, and a subsequent bone marrow aspiration and biopsy raised concern for a COVID-19 induced hemophagocytic lymphohistiocytosis. In addition, MDS could not be ruled out. The patient was thus referred to our institute for further management. The patient's peripheral blood showed pancytopenia with occasional dysplastic neutrophils and a few teardrop cells. Given the diagnostic uncertainty, a bone marrow aspiration and a biopsy were repeated revealing a hypercellular bone marrow with erythroid hyperplasia, megakaryocytic hyperplasia, trilineage dysplasia, increased blasts (13%), many ring sideroblasts, and mild to moderate myelofibrosis, consistent with MDS-EB-2. Chromosomal analysis revealed isochromosome 14. Next generation sequencing demonstrated SF3B1 K700E mutation. Discussion and conclusion The diagnosis of MDS can be challenging, particularly in young patients. Cytopenia and myelodysplastic features have been reported in COVID-19 patients, making the diagnosis of MDS more elusive. A careful pathologic examination of the bone marrow with ancillary studies including flow cytometry, immunohistochemistry, and cytogenetic and molecular studies in combination with a thorough clinical evaluation, leads to the accurate diagnosis.

Research on the mechanism of high glucose affecting the apoptosis of schwann cells by Nox4 NADPH oxidase / 中国应用生理学杂志

OBJECTIVE@#To investigate the mechanism of high glucose affecting the apoptosis of schwann cells through Nox4 NADPH oxidase.@*METHODS@#The schwann cells of newborn Wistar rats were cultured in vitro. The cultured cells were divided into four groups: control group, high-glucose group, NOX4 siRNA group and control siRNA group (n=10). The WST-1 method was used to detect the cell vitality, and the DCFH-DA method was used to detect the contents of intracellular reactive oxygen free radicals (ROS). Nox4 and Caspase3 mRNA expressions were detected by real-time fluorescence quantitative RT-PCR. Nox4 and Caspase3 protein expressions were determined by Western blot.@*RESULTS@#High glucose culture up-regulated Nox4 mRNA and protein expressions of schwann cells, decreased activity of schwann cells, increased intracellular ROS content, and promoted apoptosis by increasing Caspase3 mRNA and protein expressions. NOX4 siRNA blocked the accumulation of ROS in the high glucose cultured schwann cells, and reduced the damage of glucose on cell viability, by inhibiting NOX4 gene expression. NOX4 siRNA also reduced cell apoptosis by down-regulating Caspase3 mRNA and protein expressions.@*CONCLUSION@#Nox4 was involved in the hyperglycemic-induced apoptosis of schwann cells through ROS. The regulation of Nox4 expression or function might be a new way to treat diabetic peripheral neuropathy.

The average time of follow-up was 13 months.</p><p><b>RESULTS</b>At the last follow-up, 66.0% (66/100) patients survived, 53.0% (53/100) patients survived without leukemia, 28.0% (28/100) patients relapsed and 34.0% (34/100) patients died, 44.1% patients of them died from infectious pulmonary complications. During transplantation, 65.0% of the patients were suffered from lung infection. The overall survival (OS) and disease-free survival (DFS) of all cases was 60.9% and 48.8%, respectively. The recurrence rate was significantly higher in non-remission (66.7%) than in CR (21.2%) patients (P < 0.05). The cumulative incidence of GVHD in HLA-mismatched transplantation was 60.8%, which was significantly higher than that of HLA-matched transplantation (38.8%) (P < 0.05).</p><p><b>CONCLUSION</b>Allo-HSCT can cure a significant proportion of leukemia patients, especially for those in CR status. Since the incidence of infectious pulmonary complications after allo-HSCT is still high, much more attention should be paid to it. The comprehensive prognosis of HLA-matched transplantation is better than the HLA-mis-matched transplantation.</p>
