Global trend of nondrug and nonsedativehypnotic treatment forinsomnia: a bibliometric study.

OBJECTIVE: To present a bibliometric analysis of global scientific publications on the nondrug and nonsedative hypnotic treatment of insomnia with regard to influential institutions, publications, countries, research hotspots, trends, and frontiers. METHODS: A literature review was conducted by searching the Web of Science Core Collection (WoSCC) and China National Knowledge Infrastructure (CNKI) databases to identify all publications related to the nondrug and nonsedative hypnotic treatment of insomnia from 2000 to 2021. Eligible publications were reviewed, including annual publication increments, citation analyses, international collaborations, and keyword analyses. The data were analysed using CiteSpace (vers5.8.R3, 6.1.R2 and 6.1.6, College of Computing and Informatics, Philadelphia, PA, USA) and virtualized by knowledge maps. RESULTS：In total, 9832 publications were included in this analysis. The results from the WoSCC showed that the United States of America (Count = 2268, 40.33%), Stanford University (Count = 141, 2.51%), and the United States Department of Health and Human Services were the leading country, institute, and funding agency regarding the number of publications, respectively. 'Cognitive-behavioural therapy" was the most popular research topic generated from the cocited reference. The most frequently co-occurring keywords were insomnia, cognitive behavioural therapy, disorder, depression, quality of life, Meta-analysis, older adult, sleep, prevalence and efficacy, while keywords including clinical practice guideline, guideline, and Tai Chi remained popular after 2021. Circadian rhythm was the strongest research frontier for 2000-2021. In China, Chengdu University of Traditional Chinese Medicine (Count = 69, 4.79%) was the most productive institute in this field. The most frequently co-occurring keywords from Chinese literature were sleep disorder, sleep quality, acupuncture and moxibustion, Parkinson's disease, transcranial magnetic stimulation, health education, music therapy, chronic insomnia, quality of life, and nonmotor symptoms. Traditional Chinese medicine was the strongest research frontier for 2019-2021. CONCLUSION: This bibliometric study provides an exhaustive mapping encompassing pertinent institute, publications, influential articles, researchers and topics of the global trend of nondrug and nonsedative hypnotic treatment for insomnia. The results show that the research trend has shifted from primary studies on the efficacy and safety of nondrug and nonsedative hypnotic treatment for insomnia to comorbidity studies. Clinical practice guidelines will potentially become the research frontier for this field post-2021. The findings are important for researchers, clinicians, journal editors, and policy-makers working in the field of nondrug and nonsedative hypnotic treatment for insomnia to understand the strengths and potentials in the current studies and guide future clinical practice, research, and science policy.

Mxenes for membrane separation: from fabrication strategies to advanced applications.

Transition metal carbides/nitrides/carbonitrides, commonly referred to as MXenes, have gained widespread attention since their discovery in 2011 as a promising family of two-dimensional (2D) materials. Their impressive chemical, electrical, thermal, mechanical, and biological properties have fueled a surge in research focused on the synthesis and application of MXenes in various fields, including membrane-based separation. By engineering the materials and membrane structures, MXene-based membranes have demonstrated remarkable separation performance and added functionalities, such as antifouling and photocatalytic properties. In this review, we aim to have a timely and critical review of research on their fabrication strategy and performance in advanced molecular separation and ion exchange, beginning with a brief introduction of the preparation and physicochemical properties of MXenes. Finally, outlooks and future works are outlined with the aims to provide valuable insights and guidance for advancing membranes' applications in different separation domains.

Cardiac-specific deletion of BRG1 ameliorates ventricular arrhythmia in mice with myocardial infarction.

Malignant ventricular arrhythmia (VA) after myocardial infarction (MI) is mainly caused by myocardial electrophysiological remodeling. Brahma-related gene 1 (BRG1) is an ATPase catalytic subunit that belongs to a family of chromatin remodeling complexes called Switch/Sucrose Non-Fermentable Chromatin (SWI/SNF). BRG1 has been reported as a molecular chaperone, interacting with various transcription factors or proteins to regulate transcription in cardiac diseases. In this study, we investigated the potential role of BRG1 in ion channel remodeling and VA after ischemic infarction. Myocardial infarction (MI) mice were established by ligating the left anterior descending (LAD) coronary artery, and electrocardiogram (ECG) was monitored. Epicardial conduction of MI mouse heart was characterized in Langendorff-perfused hearts using epicardial optical voltage mapping. Patch-clamping analysis was conducted in single ventricular cardiomyocytes isolated from the mice. We showed that BRG1 expression in the border zone was progressively increased in the first week following MI. Cardiac-specific deletion of BRG1 by tail vein injection of AAV9-BRG1-shRNA significantly ameliorated susceptibility to electrical-induced VA and shortened QTc intervals in MI mice. BRG1 knockdown significantly enhanced conduction velocity (CV) and reversed the prolonged action potential duration in MI mouse heart. Moreover, BRG1 knockdown improved the decreased densities of Na+ current (INa) and transient outward potassium current (Ito), as well as the expression of Nav1.5 and Kv4.3 in the border zone of MI mouse hearts and in hypoxia-treated neonatal mouse ventricular cardiomyocytes. We revealed that MI increased the binding among BRG1, T-cell factor 4 (TCF4) and ß-catenin, forming a transcription complex, which suppressed the transcription activity of SCN5A and KCND3, thereby influencing the incidence of VA post-MI.

Effect of follicle-stimulating hormone and luteinizing hormone on apoptosis, autophagy, and the release and reception of some steroid hormones in yak granulosa cells through miR-23a/ASK1 axis.

Follicle-stimulating hormone (FSH), luteinizing hormone (LH), miR-23a, apoptosis signal-regulating kinase 1(ASK1)/c-Jun N-terminal kinase (JNK), autophagy and apoptosis play crucial roles in follicular development. However, their role in yak granulosa cells (GCs) remains unknown. Therefore, we examined the effect of miR-23a, ASK1, FSH, and LH on apoptosis, autophagy, and the release and reception of some steroid hormones in these cells. Our results showed that miR-23a overexpression significantly increased the abundance of Beclin1, the LC3II/I ratio, and the number of Ad-mRFP-GFP-LC3-labeled autophagosomes, and decreased p62 abundance. Additionally, Bax abundance and the number of terminal deoxynucleotidyl transferase deoxynucleotide triphosphate nick end labeling-positive cells were reduced, while Bcl2 expression was increased. Overexpression of miR-23a also significantly increased the abundance of estradiol receptor α (ER-α) and ß (ER-ß) and the concentrations of estradiol (E2), progesterone (P4) in yak GCs. Here, treating yak GCs with miR-23a decreased ASK1 expression, which regulates ASK1/JNK-mediated apoptosis, autophagy, E2 and P4 levels, and ER-α/ß abundance. In contrast, treatment of yak GCs with FSH (10 µg/mL) and LH (100 µg/mL) increased miR-23a abundance, regulating the subsequent effect on ASK1/JNK-mediated apoptosis, autophagy, ER-α/ß abundance, and E2 and P4 concentrations. In conclusion, miR-23a enhances autophagy in yak GCs, attenuates apoptosis, and increases ER-α/ß abundance and E2 and P4 concentrations by downregulating ASK1. Additionally, FSH and LH can regulate these effects of miR-23a by altering its expression. These results provide important insights that can inform the development of strategies to reduce abnormal follicular atresia and improve the reproductive rate of yaks.

Pangenome obtained by long-read sequencing of 11 genomes reveal hidden functional structural variants in pigs.

Long-read sequencing (LRS) facilitates both the genome assembly and the discovery of structural variants (SVs). Here, we built a graph-based pig pangenome by incorporating 11 LRS genomes with an average of 94.01% BUSCO completeness score, revealing 206-Mb novel sequences. We discovered 183,352 nonredundant SVs (63% novel), representing 12.12% of the reference genome. By genotyping SVs in an additional 196 short-read sequencing samples, we identified thousands of population stratified SVs. Particularly, we detected 7,568 Tibetan specific SVs, some of which demonstrate significant population differentiation between Tibetan and low-altitude pigs, which might be associated with the high-altitude hypoxia adaptation in Tibetan pigs. Further integrating functional genomic data, the most promising candidate genes within the SVs that might contribute to the high-altitude hypoxia adaptation were discovered. Overall, our study generates a benchmark pangenome resource for illustrating the important roles of SVs in adaptive evolution, domestication, and genetic improvement of agronomic traits in pigs.

Influencing factors for overweight and obesity in children with type 1 diabetes mellitus / 中华实用儿科临床杂志

Type 1 diabetes mellitus (T1DM) in children used to be manifested as emaciation, and overweight and obese children with T1DM are less observed.Therefore, these special population has not been concerned.However, in recent years, with the increase in the prevalence of T1DM in children, the rates of overweight and obese children with T1DM have on the rise.Overweight and obesity not only affect the growth and development of children, but also increases the risk of complications of T1DM that negatively affect the prognosis.Therefore, overweight and obesity have become a new problem in the long-term management of T1DM.This review aims to summarize the influencing factors for overweight and obesity in children with T1DM during follow-up, thus highlighting the management of the special population.This review provides reference for the monitoring of risk population of children with T1DM, timely performing clinical management and optimizing the therapeutic strategy of T1DM.

Clinical characteristics of hypersensitivity pneumonitis: non-fibrotic and fibrotic subtypes / 中华医学杂志(英文版)

BACKGROUND@#The presence of fibrosis is a criterion for subtype classification in the newly updated hypersensitivity pneumonitis (HP) guidelines. The present study aimed to summarize differences in clinical characteristics and prognosis of non-fibrotic hypersensitivity pneumonitis (NFHP) and fibrotic hypersensitivity pneumonitis (FHP) and explore factors associated with the presence of fibrosis.@*METHODS@#In this prospective cohort study, patients diagnosed with HP through a multidisciplinary discussion were enrolled. Collected data included demographic and clinical characteristics, laboratory findings, and radiologic and histopathological features. Logistic regression analyses were performed to explore factors related to the presence of fibrosis.@*RESULTS@#A total of 202 patients with HP were enrolled, including 87 (43.1%) NFHP patients and 115 (56.9%) FHP patients. Patients with FHP were older and more frequently presented with dyspnea, crackles, and digital clubbing than patients with NFHP. Serum levels of carcinoembryonic antigen, carbohydrate antigen 125, carbohydrate antigen 153, gastrin-releasing peptide precursor, squamous cell carcinoma antigen, and antigen cytokeratin 21-1, and count of bronchoalveolar lavage (BAL) eosinophils were higher in the FHP group than in the NFHP group. BAL lymphocytosis was present in both groups, but less pronounced in the FHP group. Multivariable regression analyses revealed that older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors for the development of FHP. Twelve patients developed adverse outcomes, with a median survival time of 12.5 months, all of whom had FHP.@*CONCLUSIONS@#Older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors associated with the development of FHP. Prognosis of patients with NFHP was better than that of patients with FHP. These results may provide insights into the mechanisms of fibrosis in HP.

Accuracy of Mean Value of Central Venous Pressure from Monitor Digital Display: Influence of Amplitude of Central Venous Pressure during Respiration / 中国医学科学杂志(英文版)

Background A simple measurement of central venous pressure (CVP)-mean by the digital monitor display has become increasingly popular. However, the agreement between CVP-mean and CVP-end (a standard method of CVP measurement by analyzing the waveform at end-expiration) is not well determined. This study was designed to identify the relationship between CVP-mean and CVP-end in critically ill patients and to introduce a new parameter of CVP amplitude (ΔCVP= CVPmax - CVPmin) during the respiratory period to identify the agreement/disagreement between CVP-mean and CVP-end.Methods In total, 291 patients were included in the study. CVP-mean and CVP-end were obtained simultaneously from each patient. CVP measurement difference (|CVP-mean - CVP-end|) was defined as the difference between CVP-mean and CVP-end. The ΔCVP was calculated as the difference between the peak (CVPmax) and the nadir value (CVPmin) during the respiratory cycle, which was automatically recorded on the monitor screen. Subjects with |CVP-mean - CVP-end|≥ 2 mmHg were divided into the inconsistent group, while subjects with |CVP-mean - CVP-end| < 2 mmHg were divided into the consistent group.Results ΔCVP was significantly higher in the inconsistent group [7.17(2.77) vs.5.24(2.18), P<0.001] than that in the consistent group. There was a significantly positive relationship between ΔCVP and |CVP-mean - CVP-end| (r=0.283, P <0.0001). Bland-Altman plot showed the bias was -0.61 mmHg with a wide 95% limit of agreement (-3.34, 2.10) of CVP-end and CVP-mean. The area under the receiver operating characteristic curves (AUC) of ΔCVP for predicting |CVP-mean - CVP-end| ≥ 2 mmHg was 0.709. With a high diagnostic specificity, using ΔCVP<3 to detect |CVP-mean - CVP-end| lower than 2mmHg (consistent measurement) resulted in a sensitivity of 22.37% and a specificity of 93.06%. Using ΔCVP>8 to detect |CVP-mean - CVP-end| >8 mmHg (inconsistent measurement) resulted in a sensitivity of 31.94% and a specificity of 91.32%.Conclusions CVP-end and CVP-mean have statistical discrepancies in specific clinical scenarios. ΔCVP during the respiratory period is related to the variation of the two CVP methods. A high ΔCVP indicates a poor agreement between these two methods, whereas a low ΔCVP indicates a good agreement between these two methods.

Study on the objectivity and biological mechanism of Psoralea corylifolia Linn.'s 'Great dryness damages the liver' / 药学学报

According to the theory of 'Xingben Dazao' of Psoralea corylifolia Linn. (BL), the susceptible syndromes and biomarkers of liver injury caused by BL were searched. Rat models of kidney-yin deficiency syndrome (M_yin) and kidney-yang deficiency syndrome (M_yang) were established, and all animal experimental operations and welfare following the provisions of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Traditional Chinese Medicine (No. YFYDW2020017). The results showed that BL significantly decreased the body weight, water intake, and urine weight of M_yin rats and increase the organ indexes of the liver, testis, adrenal gland, and spleen and the expression of alanine aminotransferase (ALT). Meantime, BL significantly increased the urine weight of M_yang rats and decreased the expression of ALT and aspartate aminotransferase (AST). Hematoxylin and eosin (HE) staining showed that BL could aggravate inflammatory infiltration of hepatocytes in rats with M_yin and alleviate liver injury in rats with M_yang. Metabolomics identified 17 BL co-regulated significant differential metabolic markers in M_yin and M_yang rats. Among them, 8 metabolites such as glutamine, quinolinate, biliverdin, and lactosylceramide showed opposite trends, mainly involving cysteine and methionine metabolism, tyrosine metabolism, tryptophan metabolism, purine metabolism, sphingolipid metabolism, glycerol phospholipid metabolism, glutamine metabolism, and other pathways. M_yin/M_yang may be the susceptible constitution of BL for liver damage or protection, which may be related to the regulation of amino acid metabolism and sphingolipid metabolism. The study can provide some experimental data support for the safe and accurate use of BL in the clinical practice of traditional Chinese medicine.

OBJECTIVE@#To investigate the effect of a water-soluble novel dihydroartemisinin dimer containing nitrogen atoms SM 1044 on the apoptosis of all-trans retinoic acid (ATRA) resistant acute promyelocytic leukemia (APL) NB4-R1 cells and its potential mechanism.@*METHODS@#The effects of SM 1044 on cell apoptosis, mitochondrial transmembrane potential, and the level of reactive oxygen species (ROS) were assessed by flow cytometry. Expressions of apoptosis-related proteins were determined by Western blot. The effects of SM 1044 on MAPK (ERK, JNK) signaling pathway, PML/RARα fusion protein, and expressions of apoptosis-related proteins were detected by Western blot.@*RESULTS@#SM 1044 could significantly induce apoptosis and the loss of mitochondrial transmembrane potential in NB4-R1 cells, and activate apoptosis-related proteins caspase-3, caspase-8, caspase-9 and poly (ADP-ribose) polymerase (PARP). SM 1044 could also induce NB4-R1 cells to produce ROS. Western blot showed that SM 1044 activated the phosphorylation of MAPK (ERK, JNK) signaling pathway and down-regulated the expression of PML/RARα fusion protein.@*CONCLUSION@#SM 1044 can induce apoptosis of ATRA resistant APL NB4-R1 cells, which may be related to ROS/ERK and ROS/JNK signaling pathway, and can also induce by down-regulating PML/RARα fusion protein.

Clinical and genetic analyses of Joubert syndrome in children / 中国当代儿科杂志

OBJECTIVES@#To study the clinical and genetic features of Joubert syndrome (JS) in children.@*METHODS@#A retrospective analysis was performed on the clinical data, genetic data, and follow-up data of 20 children who were diagnosed with JS in the Department of Children's Rehabilitation, the Third Affiliated Hospital of Zhengzhou University, from January 2017 to July 2022.@*RESULTS@#Among the 20 children with JS, there were 11 boys and 9 girls. The common clinical manifestations were developmental delay (20 children, 100%), abnormal eye movement (19 children, 95%), and hypotonia (16 children, 80%), followed by abnormal respiratory rhythm in 5 children (25%) and unusual facies (including prominent forehead, low-set ears, and triangular mouth) in 3 children (15%), and no limb deformity was observed. All 20 children (100%) had the typical "molar tooth sign" and "midline cleft syndrome" on head images, and 6 children (30%) had abnormal eye examination results. Genetic testing was performed on 7 children and revealed 6 pathogenic genes, i.e., the CPLANE1, RPGRIP1L, MKS1, CC2D2A, CEP120, and AHI1 genes.@*CONCLUSIONS@#For children with developmental delay, especially those with abnormal eye movement and hypotonia, it is recommended to perform a head imaging examination to determine the presence or absence of "molar tooth sign" and "midline cleft syndrome", so as to screen for JS to avoid missed diagnosis and misdiagnosis. There are many pathogenic genes for JS, and whole-exome sequencing can assist in the diagnosis of JS.

Association between cardiometabolic diseases and quality of life and the mediation effect of perceived stress / 中华心血管病杂志

Objective: To explore the association between cardiometabolic diseases (CMD) and quality of life, the association between CMD and perceived stress, and the mediation effect of perceived stress on the association between CMD and quality of life, and to provide evidence for the prevention and treatment of CMD and the improvement of quality of life in these patients. Methods: This is a cross-sectional study. Data were collected by the employees' physical examination of a company in Xi'an in 2021. Multiple linear regression models were used to analyze the association between the status of CMD (divided into three categories: no CMD, presence of one kind of CMD, and with≥2 kinds of CMD (≥2 kinds of CMD were defined as cardiometabolic multimorbidity (CMM)), quality of life, and perceived stress. Mediation analysis with a multi-categorical independent variable was conducted to determine the mediation effect of perceived stress on the association between CMD and quality of life. Results: Among all 4 272 participants, 1 457 (34.1%) participants had one kind of CMD and 677 (15.8%) participants had CMM. The average scores for quality of life and perceived stress were (57.5±15.7) and (16.9±7.9), respectively. Compared with participants without CMD, after adjusting for demographic and lifestyle factors, no statistically significant associations were observed between one kind of CMD and perceived stress or quality of life (both P>0.05). Perceived stress did not mediate the association between one kind of CMD and quality of life. However, participants with CMM had lower quality of life and higher perceived stress than participants without CMD. The relative total effect coefficient c (95%CI) and the relative direct effect coefficient c' (95%CI) between CMM and quality of life were -3.71 (-5.04--2.37) and -2.52 (-3.81--1.24) (both P<0.05), respectively. The relative indirect effect coefficient a2b (95%CI) of perceived stress on the association between CMM and quality of life was -1.18 (-1.62--0.77) (P<0.05). The mediation effect size was 31.8%. Conclusions: CMM is negatively associated with quality of life and positively associated with perceived stress. Perceived stress partially mediates the association between CMM and quality of life. Our results suggest that, in addition to preventing and treating CMM actively, efforts should be taken to relieve the perceived stress of people with CMM to improve their quality of life.

Clinical effect of Kangfuxin solution combined with lidocaine and gentamicin in the treatment of oral ulcer / 药学实践杂志

Objective To investigate the clinical efficacy of Kangfuxin solution combined with lidocaine and gentamicin in the treatment of oral ulcers. Method A total of 120 patients with oral ulcer admitted to Tongzhou District Maternity and Child Health Care Hospital of Beijing from May 2019 to July 2021 were selected and divided into observation group and control group randomly. 58 patients were treated with lidocaine as a control group and 62 patients in the observation group were treated with Kangfuxin solution combined with lidocaine and gentamicin. The clinical efficacy, including oral ulcer condition, visual analogue scale (VAS score) after 3d and 5d of treatment, inflammatory factor levels and adverse reactions were observed and compared between the two groups before and after treatment. Results The overall effective rate of the treatment group (95.12%) was higher than that of the control group (74.36%) and the difference was statistically significant (P<0.05). The ulcer area, ulcer healing time, and chewing improvement period were remarkably reduced compared with those in the control group (P<0.05). The VAS scores after 3d and 5d of treatment, the levels of tumor necrosis factor-α (TNF-α), C-reactive protein (CRP) and interleukin-6 (IL-6) between the two groups were statistically significant (P<0.05). There was no significant difference in the incidence of adverse reactions (3.22%) between the observation group and the control group (6.90%) (P>0.05). Conclusion Kangfuxin solution combined with lidocaine and gentamicin showed better curative effect on oral ulcer. This treatment regimen could effectively ameliorate various clinical symptoms of patients with oral ulcer, reduce patient pain and downregulate the levels of inflammatory factors, and help patients recover with high safety profile.

Expert Consensus on Acute Respiratory Failure in Critically Ill Cancer Patients (2023) / 中国医学科学杂志(英文版)

Objective This consensus aims to provide evidence-based recommendations on common questions in the diagnosis and treatment of acute respiratory failure (ARF) for critically ill cancer patients.Methods We developed six clinical questions using the PICO (Population, Intervention, Comparison, and Outcome) principle in diagnosis and treatment for critical ill cancer patients with ARF. Based on literature searching and meta-analyses, recommendations were devised. The GRADE (Grading of Recommendation Assessment, Development and Evaluation) method was applied to each question to reach consensus in the expert panel. Results The panel makes strong recommendations in favor of (1) metagenomic next-generation sequencing (mNGS) tests may aid clinicians in rapid diagnosis in critically ill cancer patients suspected of pulmonary infections; (2) extracorporeal membrane oxygenation (ECMO) therapy should not be used as a routine rescue therapy for acute respiratory distress syndrome in critically ill cancer patients but may benefit highly selected patients after multi-disciplinary consultations; (3) cancer patients who have received immune checkpoint inhibitor therapy have an increased incidence of pneumonitis compared with standard chemotherapy; (4) critically ill cancer patients who are on invasive mechanical ventilation and estimated to be extubated after 14 days may benefit from early tracheotomy; and (5) high-flow nasal oxygen and noninvasive ventilation therapy can be used as a first-line oxygen strategy for critically ill cancer patients with ARFs. A weak recommendation is: (6) for critically ill cancer patients with ARF caused by tumor compression, urgent chemotherapy may be considered as a rescue therapy only in patients determined to be potentially sensitive to the anticancer therapy after multidisciplinary consultations. Conclusions The recommendations based on the available evidence can guide diagnosis and treatment in critically ill cancer patients with acute respiratory failure and improve outcomes.

Impact of non-valvular atrial fibrillation on global cognitive function and executive function / 中华心血管病杂志

Objective: To explore the impact of non-valvular atrial fibrillation (AF) on the global cognitive function and executive function of patients without dementia, and to observe the differences between different types of AF. Methods: This research is a prospective and cross-sectional study. Non-dementia patients admitted to the department of neurology in the third people's hospital of Chengdu from July 2018 to July 2019 were included. Patients with non-valvular AF were included in the AF group and those with sinus rhythm were included in the control group. General clinical data and compared global cognitive function (mini-mental state examination (MMSE) and montreal cognitive assessment (MOCA)) and executive function (shape trails test (STT) and stroop color and word test (SCWT)) data were obtained and compared between 2 groups, and between different AF type groups. Results: A total of 386 participants were included, including 203 in AF group (52.6%), age was 68 (63, 71) years old, 119 were male (58.6%) and 183 in control group, age was 68 (63, 71) years old, 101 were male (55.2%). MMSE(28 (27, 29)) and MOCA (25 (22, 26)) scores were lower in AF group than those in control group (P<0.05), while STT-A time (84 (64, 140) s), STT-B time (248 (184, 351) s), STT time difference((159 (106, 245) s), SCWT-A time (50 (50, 50) s), SCWT-B time (55 (46, 63) s), SCWT-C time (100 (86, 120) s) and SCWT time interference (46 (34, 65) s) were higher than those in control group (P<0.05). Moreover, there was no difference in above indexes between paroxysmal AF and non-paroxysmal AF. Conclusion: The global cognitive function and executive function of patients with non-valvular AF are both decreased, while there is no obvious difference of the global cognitive function and executive function between paroxysmal AF and non-paroxysmal AF patients.

Efficacy of stimulating Mingmen (GV4) and Guanyuan (CV4) on kidney deficiency in rat model: laser irradiation traditional moxibustion.

OBJECTIVE: To investigate the effect of 10.6-µm laser moxibustion (LM) and traditional moxibustion (TM) on kidney deficiency (KYD) model rats. METHODS: Forty rats were randomly divided into normal, model, 10.6-µm LM, and TM groups. KYD was induced through intramuscular hydrocortisone injections. RESULTS: Hydrocortisone injections decreased the body weight, activity, and temperature and induced changes in the organ coefficients. Compared with the model group, TM and LM treatment prevented body weight loss and improved organ coefficients after treatment ( < 0.05), while the body weight remained lower compared to the normal group ( < 0.01). Additionally, LM and TM significantly increased the levels of urine 17-hydroxycorticosteroid (17-OHCS) compared with the model group ( < 0.01). The LM and TM groups showed a greater distance travelled across the central area, time spent in the central area, and 5-min total distance than the model group in the open field test ( < 0.01). The model group had the lowest anal or surface temperature ( < 0.05); there were no differences among the other three groups ( > 0.05). TM treatment increased the temperature of Mingmen (GV4) and Guanyuan (CV4) compared to the model group ( < 0.05, < 0.01). LM treatment increased Mingmen (GV4) temperature ( < 0.05), while there were no obvious differences in Guanyuan (CV4) temperature compared with the normal group before and after treatment ( > 0.05). There was a positive correlation between Mingmen (GV4)/Guanyuan (CV4) temperature and 17-OHCS levels. CONCLUSIONS: LM and TM treatment can improve KYD symptoms, and acupoint temperature changes may be an objective indicator of KYD.

Y-shaped DNA nanostructures assembled-spherical nucleic acids as target converters to activate CRISPR-Cas12a enabling sensitive ECL biosensing.

Considering the trans-cleavage capabilities, high-specificity and programmability, the CRISPR-Cas system has been recognized as a valuable platform to develop the next-generation diagnostic biosensors. However, due to the natural interaction with nucleic acids, current CRISPR-Cas-based detection mostly applies in nucleic acid analysis rather than non-nucleic acid analysis. By virtue of spherical nucleic acids (SNAs) with programmability and specificity, the Y-shaped DNA nanostructures assembled-SNAs (Y-SNAs) were rationally designed as target converters to achieve the quantitative activation of CRISPR-Cas12a, enabling a highly specific and sensitive electrochemiluminescence (ECL) determination of alpha-methylacyl-CoA racemase (AMACR), a high specific protein biomarker of prostate cancer. Significantly, the Y-shaped DNA nanostructures comprised of assisted DNA (A1), AMACR aptamer and DNA activator of CRISPR-Cas12a were loaded on Au nanoparticles modified Fe3O4 magnetic beads (Au@Fe3O4 MBs) to construct the robust Y-SNAs. In the presence of the target AMACR, the Y-SNAs as target converters could achieve quantitative activation of CRISPR-Cas12a by outputting the DNA activators with a linear relationship to the target. The amplified ECL signals were triggered by the release of the ferrocene-labeled quenching probes (QPs) on the electrode surface due to the trans-cleavage activity of CRISPR-Cas12a, thereby realizing the sensitive ECL determination of AMACR from 10 ng/mL to 100 µg/mL with the detection limit of 1.25 ng/mL. In general, this approach provides novel perspectives on how to design a universal ECL platform of the CRISPR-Cas system to detect the non-nucleic acid targets beyond the traditional methods.

Deep medullary veins and cerebral small vessel disease / 国际脑血管病杂志

Cerebral small vessel disease (CSVD) refers to a series of pathological, imaging and clinical syndrome caused by various etiologies affecting cerebral arterioles, venules and capillaries. The main imaging features of CSVD include white matter hyperintensities, cerebral microbleeds, lacunar cerebral infarction, enlarged perivascular space, and brain atrophy. Deep medullary veins (DMVs) are small parenchymal veins around the lateral ventricle, which participate in the venous return from deep white matter veins to subependymal veins. In recent years, more and more studies have shown that DMVs are closely associated with the occurrence and development of CSVD. This article reviews the role of DMVs in CSVD, and provides ideas for further exploring the pathogenesis and imaging markers of CSVD.

Inhibition of activated K-opioid receptor to myocardical hypertrophy induced by ET-1 in neonatal rats by extracellular signal-regulated kinase pathway / 中国药理学通报

Aim To investigate the inhibitory effect of kappa-opioid receptor(κ-OR)stimulation on extracellular signal-regulated kinase pathway on ET-1-induced cardiomyocyte hypertrophy in vitro cultured myocardial cells from neonatal rats.Methods Myocardial cells of neonatal rats were cultured in vitro.The hypertrophic myocytes were induced by ET-1(10 nmol·L-1)before κ-OR agonist U50488H(1 μmol·L-1)was administered.The antihypertrophic effect of κ-OR stimulation was observed in the presence of U0126(1μmol·L-1), Ro-31-8220(50 nmol·L-1)and PTX(5 mg·L-1).The cardiomyocytes volume was measured by computer photographalysis system.The relative expression of ERK1/2 was determined by Western blot.The morphological changes in cardiomyocytes were observed under an inverted phase contrast microscope.The expression of mRNA of atrial natriuretic peptide(ANP)was determined by RT-PCR.Results Compared with normal control group, ET-1 could induced cardiomyocyte hypertrophy.Compared with ET-1 model group, U50488H(1 μmol·L-1)could obviously inhibit ET-1-induced increase of the cardiomyocytes volume, expression of ANPmRNA and expression of ERK1/2, which was similar to U0126(1 μmol·L-1)and Ro-31-8220(50 nmol·L-1); however, the inhibitory effects of U50488H were partly lost when preincubated with U0126(1 μmol·L-1)and Ro-31-8220(50 nmol·L-1); the inhibitory effects of U50488H, U0126(1 μmol·L-1)and Ro-31-8220(50 nmol·L-1)were lost when preincubated with NOR-BNI.Conclusion The stimulation of kappa-opiod can inhibit myocardial hypertrophy induced by ET-1, which is possibly via attenuating ERK1/2.

Recommendations of diagnosis and treatment of adult-onset Still′s disease in China / 中华内科杂志

Adult-onset Still′s disease (AOSD) is a rare systemic autoinflammatory disorder. In China, standardized diagnosis and treatment for AOSD is insufficient. Based on the evidence from China and other countries, Chinese Rheumatology Association developed standardization of diagnosis and treatment of AOSD in China. The purpose is to standardize the methods for diagnosis of AOSD, treatment strategies, and reduce misdiagnosis, missed diagnosis and irreversible damage.
