Informed consent in psychological counseling is the first step for clients to initiate the counseling process， and the degree and effectiveness of informed consent are important factors that determine the subsequent effectiveness and development of psychological counseling. By elaborating on the connotation and importance of informed consent in psychological counseling， the ethical dilemmas of the issue of informed consent in psychological counseling were classified and summarized. There were ethical dilemmas， such as the lack of consensus， procedural guarantee mechanisms， special clients procedures and informed consent principles， as well as non-standard informed consent procedures in online psychological counseling. The paper also proposed to clarify the explanatory obligations of counselors， strengthen procedural ethical constraints， formulate special norms for informed consent for special subjects， and enhance the ethical education and capacity building of psychological counselors.

ObjectiveTo explore the potential mechanism of Dingchuan Granule （定喘颗粒， DG） in the treatment of respiratory syncytial virus （RSV） pneumonia. MethodsA total of 60 male Sprague Dawley （SD） rats were randomly divided into control group， model group， ribavirin group， DG low-dose group， DG middle-dose group， and DG high-dose group， with 10 rats in each group. Except for the control group， rats were administrated with RSV via intranasal drip. After model establishment， the DG low-， middle-， and high-dose groups were administrated via oral gavage with DG at 3.47， 6.93， and 13.86 g/（kg·d） respectively， while the ribavirin group was administrated via oral gavage with ribavirin at 15.75 mg/（kg·d）. The drug was given once daily for one week. The rats in the control group and the model group were not given any drug， only subjected to the grasping action. Twenty-four hours after the last administration， the pathological changes of lung tissues were observed and scored using HE staining. The levels of serum inflammatory factors， including tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and interleukin-6 （IL-6）， were detected by colorimetry. The protein levels of nuclear factor （erythroid derived 2）-like 2 （Nrf2）， Kelch-like ECH-associated protein 1 （Keap1）， heme oxygenase 1 （HO-1）， and NAD（P）H quinone dehydrogenase 1 （NQO1） in lung tissues were measured by Western Blot. The RSV load as well as the gene expression levels of Nrf2， Keap1， HO-1， and NQO1 in lung tissues were determined by qRT-PCR. The level of reactive oxygen species （ROS） in rat lung tissues was detected using chemiluminescence. The levels of glutathione （GSH） and malondialdehyde （MDA） in rat lung tissues were measured by a microassay. ResultsCompared with the control group， other groups had significant increases in pathological score of lung tissue， RSV load， levels of ROS， MDA， serum TNF-α， IL-1β， and IL-6； decrease in GSH level， increases in expression level of Keap1 protein and its mRNA in lung tissue， and significant decrease in levels of Nrf2， HO-1， expression level of NQO1 protein and its mRNA （P＜0.05）. Compared with the model group， all the above-mentioned indicators in the DG low-， middle-， and high-dose groups and the ribavirin group were improved to varying degree （P＜0.05）. The levels of serum TNF-α， IL-1β， and IL-6 in rats of DG dose groups showed a dose-dependent pattern， the DG high-dose group exhibiting the best effect （P＜0.05）. The DG high-dose group was superior to the DG low- and middle-dose groups in reducing the levels of ROS and MDA， and increasing the level of GSH in lung tissues （P＜0.05）. The DG high-dose group and the ribavirin group had better effect than the DG middle-dose group in reducing the RSV load （P＜0.05）. The DG high-dose group was superior to the ribavirin group in improving the protein levels of Nrf2， Keap1， HO-1， and NQO1 （P＜0.05）. ConclusionDG could inhibit oxidative stress by regulating the Nrf2/Keap1/HO-1/NQO1 signaling pathway to improve pulmonary inflammation and treat RSV pneumonia， with the DG high-dose group showing the best effect.

Ketamine， a non-competitive N-methyl-D-aspartate （NMDA） receptor antagonist， has gained increasing attention for its rapid antidepressant effects in treatment-resistant depression （TRD） and suicidal ideation. Its mechanisms include NMDA receptor blockade， AMPA receptor activation， and upregulation of BDNF/mTOR signaling. Its enantiomers， esketamine and R-ketamine， as well as its metabolites， exhibit differences in efficacy and mechanisms. Intranasal esketamine has been approved in the Europe， United States， and China for TRD， demonstrating rapid efficacy in alleviating depressive symptoms and acute suicidal ideation. In contrast， R-ketamine demonstrates potential for longer-lasting effects and a improved safety profile. This review summarizes recent advances in the pharmacology， pharmacokinetics， and clinical applications of ketamine and its enantiomers in depressive disorders， bipolar disorder， substance use disorders， post-traumatic stress disorder and obsessive-compulsive disorder. Despite ketamine's multifaceted therapeutic potential， safety concerns such as dissociation， cognitive impairment， and abuse liability warrant continued attention.［Funded by Key Project of Natural Science Research for Universities of Anhui Provincial Education Department （number， 2023AH050647）； Anhui Provincial Department of Education Outstanding Young Talent Support Program Project 2022 （number， gxyqZD2022022）］

Objective To investigate the effect of FUNDC1 tyrosine phosphorylation site mutations on mitophagy in H9c2 myocardial cells by constructing tyrosine site mutant plasmids (Y11 and Y18) of the FUN14 domain-containing protein 1 (FUNDC1). Methods The mutant plasmids constructed by whole-gene synthesis were transfected into rat myocardial H9c2 cells and divided into five groups: empty plasmid group, FUNDC1 overexpression group, Y11 mutant group, Y18 mutant group, and Y11 combined with Y18 mutant group. The viability of H9c2 cells was assessed using the CCK-8 assay. Additionally, tetramethylrhodamine ethyl ester (TMRE) staining was utilized to detect mitochondrial membrane potential. The protein expression levels of FUNDC1, translocase of the outer mitochondrial membrane 20 (TOM20), and cytochrome c oxidase IV (COX IV) were detected by Western blot analysis. Confocal microscopy was used to evaluate transfection efficiency as well as the co-localization of mitochondria and lysosomes. Results The FUNDC1 overexpression, Y11, Y18, and Y11 combined with Y18 mutant plasmids were successfully constructed. After plasmid transfection, widespread GFP fluorescence expression was observed under confocal microscopy. Compared with the empty plasmid group, FUNDC1 protein expression levels were significantly increased in the FUNDC1 overexpression group, Y11 mutation group, Y18 mutation group, and Y11 combined with Y18 mutation group, while cell viability and mitochondrial membrane potential showed no significant changes. Compared to the empty plasmid group, cells transfected with Y18 and Y11 combined with Y18 mutant plasmids showed increased TOM20 and COX IV expression levels and decreased mitochondrial-lysosomal co-localization. Conclusion Transfection with FUNDC1 Y18 or Y11 combined with Y18 mutant plasmids inhibited mitophagy in H9c2 myocardial cells.

The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.

OBJECTIVES: To construct vocal recognition classification models using 6 machine learning algorithms and vocal emotional characteristics of individuals with subthreshold depression to facilitate early identification of subthreshold depression. METHODS: We collected voice data from both normal individuals and participants with subthreshold depression by asking them to read specifically chosen words and texts. From each voice sample, 384-dimensional vocal emotional feature variables were extracted, including energy feature, Meir frequency cepstrum coefficient, zero cross rate feature, sound probability feature, fundamental frequency feature, difference feature. The Recursive Feature Elimination (RFE) method was employed to select voice feature variables. Classification models were then built using the machine learning algorithms Adaptive Boosting (AdaBoost), Random Forest (RF), Linear Discriminant Analysis (LDA), Logistic Regression (LR), Lasso Regression (LRLasso), and Support Vector Machine (SVM), and the performance of these models was evaluated. To assess generalization capability of the models, we used real-world speech data to evaluate the best speech recognition classification model. RESULTS: The AdaBoost, RF, and LDA models achieved high prediction accuracies of 100%, 100%, and 93.3% on word-reading speech test set, respectively. In the text-reading speech test set, the accuracies of the AdaBoost, RF, and LDA models were 90%, 80%, and 90%, respectively, while the accuracies of the other 3 models were all below 80%. On real-world word-reading and text-reading speech data, the classification models using AdaBoost and Random Forest still achieved high predictive accuracies (91.7% and 80.6% for AdaBoost and 86.1% and 77.8% for Random, respectively). CONCLUSIONS Analyzing vocal emotional characteristics allows effective identification of individuals with subthreshold depression. The AdaBoost and RF models show excellent performance for classifying subthreshold depression individuals, and may thus potentially offer valuable assistance in the clinical and research settings.

Glucosidases are an indispensable class of enzymes in the sugar metabolism of organisms. To investigate the biological functions and expression patterns of α-glucosidases (AGLUs) and β-glucosidases (BGLUs), we identified the two family members in the genome of melon (Cucumis melo). The number, location on chromosomes, gene structure, subcellular localization, conserved motifs, and phylogenetic relationship of the two family members were analyzed. Based on the cis-acting elements in the promoter region and protein interaction models, their functions were preliminarily predicted. Furthermore, the gene expression of the two family members was determined by qRT-PCR. The results showed that the melon genome contained five AGLU family members on five chromosomes, and all of the five members were located in the extracellular matrix, with the amino acid sequence lengths ranging from 899 aa to 1 060 aa. The melon genome carried 18 BGLU family members on 8 chromosomes, and all the members were located in the cell membrane or cytoplasm, with the amino acid lengths ranging from 151 aa to 576 aa. The qRT-PCR results showed that the expression of about 50% of the genes was down-regulated upon cold stress. CmAGLU5 and CmBGLU7 may be key members of the two families, respectively, in response to cold stress. The expression of all members of the two families was up-regulated under abscisic acid (ABA), high salt, and drought stress. In the AGLU family, CmAGLU3 was the key gene in response to ABA and high salt stress, while CmAGLU4 was the key gene in response to drought stress. In the BGLU family, CmBGLU18 was the key gene in response to ABA, while CmBGLU6 was the key gene in response to high salt and drought stress.

In recent years, endovascular therapy has become the most important progress in the field of the treatment of acute ischemic stroke caused by large vessel occlusion. However, the vascular recanalization shown by imaging after endovascular treatment cannot fully translate into effective tissue reperfusion and functional outcome, a phenomenon known as "futile recanalization". Combined neuroprotective therapy after vascular recanalization is expected to reduce the occurrence of futile recanalization and improve the outcome of patients. This article briefly summarizes the main application progress of commonly used neuroprotective therapies in clinical practice (edaravone dexborneol, glucocorticoids, hypothermia, and remote ischemic conditioning). It explores the trend and direction of combining endovascular therapy and neuroprotective therapy for patients with acute ischemic stroke caused by large vessel occlusion, and provides further reference and suggestions for intervention measures after endovascular therapy.

AIM: To explore a more convenient and accurate method for evaluating the anterior chamber angle width based on the Van Herick method.METHODS:A total of 58 patients(69 eyes)with age-related cataract who visited our hospital between January and December 2021 were included. They were divided into the chamber angle width ≥1/2 corneal thickness(CT)group(44 eyes of 37 cases)and <1/2CT group(25 eyes of 21 cases)according to the Van Herick method. The central anterior chamber depths and the peripheral anterior chamber angle degrees were measured by ultrasound biomicroscopy.RESULTS: There were statistically significant differences in central anterior chamber depth between the two groups(2.64±0.27 mm vs. 2.23±0.29 mm, P<0.01), and the differences of chamber angle degrees of quadrants of superior, temporal, inferior and nasal compared between two groups were all statistically significant(P<0.01). The difference of chamber angle degrees of quadrants of superior and inferior in chamber angle width ≥1/2CT group was not statistically significant(P>0.05), while the differences of chamber angle degrees of other quadrants were all statistically significant(P<0.05). The differences of chamber angle degrees of quadrants of superior and nasal, temporal and the chamber angle degrees of quadrants of inferior and temporal were all statistically significant in chamber angle width <1/2CT group(P<0.05).CONCLUSION: In the overall evaluation of the anterior chamber angle, it would be more simple, fast and accurate when evaluating the temporal chamber angle width and inferior quadrant of chamber angle width by using the Van Herick method under silt lamp.
