Perceptual decision making refers to the process by which individuals make choices and judgments based on sensory information, serving as a fundamental ability for human adaptation to complex environments. While traditional research has focused on perceptual decision making in isolated contexts, growing evidence highlights the profound influence of social contexts prevalent in real-world scenarios. As a crucial factor supporting individual survival and development, social context not only provides rich information sources but also shapes perceptual decision making through top-down processing mechanisms, prompting researchers to recognize the inherently social nature of human decisions. Empirical studies have demonstrated that social information, such as others’ choices or group norms, can systematically bias individuals’ perceptual decisions, often manifesting as conformity behaviors. Social influence can also facilitate performance under certain conditions, particularly when individuals can accurately identify and adopt high-quality social information. The impact of social context on perceptual decisions is modulated by a variety of external and internal factors, including group characteristics(e.g., group size, response consistency), attributes of peers (e.g., familiarity, social status, distinctions between human and artificial agents), as well as individual differences such as confidence, personality traits, and developmental stage. The motivations driving social influence encompass three primary mechanisms: improving decision accuracy through informational influence, gaining social acceptance through normative influence, and maintaining positive self-concept. Recent computational approaches have employed diverse theoretical frameworks to provide valuable insights into the cognitive mechanisms underlying social influence in perceptual decision making. Reinforcement learning models demonstrate how social feedback shapes future choices through reward-based updating. Bayesian inference frameworks describe how individuals integrate personal beliefs with social information based on their respective reliabilities, dynamically updating beliefs to optimize decisions under uncertainty. Drift diffusion models offer powerful tools to decompose social influence into distinct cognitive components, allowing researchers to differentiate between changes in perceptual processing and shifts in decision criteria. Collectively, these models establish a comprehensive methodological foundation for disentangling the multiple pathways by which social context shapes perceptual decisions. Neuroimaging and electrophysiological studies provide converging evidence that social context influences perceptual decision making through multi-level neural mechanisms. At early perceptual processing stages, social influence modulates sensory evidence accumulation in parietal cortex and directly alters primary visual cortex activity, while guiding selective attention to stimulus features consistent with social norms through attentional alignment mechanisms. At higher cognitive levels, the reward system (ventral striatum, ventromedial prefrontal cortex) is activated during group-consistent decisions; emotion-processing networks (anterior cingulate cortex, insula, amygdala) regulate experiences of social acceptance and rejection; and mentalizing-related brain regions (dorsomedial prefrontal cortex, temporoparietal junction) support inference of others’ mental states and social information integration. These neural circuits work synergistically to achieve top-down multi-level modulation of perceptual decision making. Understanding the mechanisms by which social context shapes perceptual decision making has broad theoretical and practical implications. These insights inform the optimization of collective decision-making, the design of socially adaptive human-computer interaction systems, and interventions for cognitive disorders such as autism spectrum disorder and anorexia nervosa. Future studies should combine computational modeling and neuroimaging approaches to systematically investigate the multi-level and dynamic nature of social influences on perceptual decision making.

OBJECTIVE To investigate the effects of esketamine for multimodal analgesia on opioid consumption and gastric motility in mechanically ventilated non-surgical intensive care unit (ICU) patients. METHODS Forty cases of mechanically ventilated non-surgical patients in the ICU of our hospital from February 1st, 2023 to July 31st, 2023 were selected and randomly divided into control group and esketamine (S-K) group using grouping method with opaque envelopes, with 20 cases in each group. Control group was given sufentanil, and S-K group was infused with Esketamine hydrochloride injection at a constant rate of 0.2 mg/(kg·h)+ sufentanil. The treatment period length, analgesic compliance rate, sedation level, analgesic and sedative consumption, and gastric motility indexes were compared between the two groups. RESULTS There was no statistically significant difference in the treatment period length, analgesic compliance rate, sedation level, or the consumption of propofol and midazolam between the two groups (P>0.05). The consumption of sufentanil in the S-K group was significantly less than control group (P< 0.05). Compared with 1 h after randomization, the antral contraction frequency, antral contraction amplitude and antral motility index of patients in the S-K group were significantly higher at 72 h after randomization and were significantly higher than control group (P<0.05). CONCLUSIONS Esketamine may reduce opioid consumption and improve gastric motility in mechanically ventilated non-surgical ICU patients while ensuring a level of analgesic sedation.

Influenza virus causes serious threat to human life and health. Due to the inherent high variability of influenza virus, clinically resistant mutant strains of currently approved anti-influenza virus drugs have emerged. Therefore, it is urgent to develop antiviral drugs with new targets or mechanisms of action. RNA-dependent RNA polymerase is directly responsible for viral RNA transcription and replication, and plays key roles in the viral life cycle, which is considered an important target of anti-influenza drug design. From the point of view of medicinal chemistry, this review summarizes current advances in diverse small-molecule inhibitors targeting influenza virus RNA-dependent RNA polymerase, hoping to provide valuable reference for development of novel antiviral drugs.

OBJECTIVE To investigate the effects and mechanism of Yiqi huoxue decoction (YQHX) on lumbar disc herniation in rats. METHODS Rats were randomly divided into sham operation group, model group, NF-κB inhibitor group (QNZ group, 1 mg/kg), YQHX group (9.1 g/kg) and combination group (YQHX+QNZ group, the same dose as each single drug group), with 10 rats in each group. Except for sham operation group, lumbar disc herniation model of rats was induced in other groups; administration groups were given QNZ intraperitoneally or/and YQHX intragastrically, once a day, for 8 consecutive weeks. The severity of intervertebral disc herniation was evaluated in each group; the pathological changes of intervertebral discs and the changes of autophagy of nucleus pulposus cells were all observed; the level of tumor necrosis factor-α (TNF-α) in serum, and the ratios of Bcl-2/adenovirus E1B interacting protein 3 (BNIP3) and Beclin-1 positive cells in intervertebral disctissues were detected; the phosphorylation of nuclear factor-κB (NF-κB) p65, the expressions of tumor necrosis factor receptor- associated factor-2 (TRAF-2), TRAF-3, BNIP3 and LC3B protein, and mRNA expressions of NF-κB p65, LC3B, p62,BNIP3 and Beclin-1 were determined. RESULTS Compared with model group, Pfirrmann grading score decreased significantly,the pathological injury of intervertebral disc tissue was relieved in YQHX group; the number of autophagosomes in nucleus pulposus cells increased; serum level of TNF-α and mRNA expression of p62 in intervertebral disc tissue decreased significantly; the ratios of BNIP3 and Beclin-1 positive cells, the phosphorylation of NF-κB p65, the expressions of TRAF-2, TRAF-3, BNIP3 and LC3B protein as well as the mRNA expressions of NF- κB p65, LC3B, BNIP3 and Beclin-1 decreased significantly in intervertebral disc tissues (P<0.05). The changes of above indexes in YQHX group were reversed partly in YQHX+QNZ group. CONCLUSIONS YQHX promotes the elevation of autophagy level of intervertebral discs, slows down the inflammatory response and the progression of lumbar disc herniation by activating the NF-κB signaling pathway.

Objective:To understand the current knowledge, attitude, and practice (KAP) on influenza and influenza vaccine among pregnant women in Suzhou and to analyze its influencing factors to provide technical support data for public health strategies for promoting influenza vaccination in pregnant women.Methods:A questionnaire was designed, and a stratified sampling method was used to conduct a face-to-face survey among pregnant women at different stages of pregnancy who received antenatal examinations at different levels of medical institutions in Suzhou, Jiangsu Province, in 2023. KAP status and influencing factors were analyzed by χ2 test and logistic regression analysis. Results:A total of 2 195 valid questionnaires were collected in this survey. The M( Q1, Q3) of knowledge about influenza and influenza vaccine among pregnant women in Suzhou was 7.60 (5.23, 9.80) points, and the score range was 0.20-14.71 points, the passing rate was 34.12%, the awareness rate of influenza vaccine was 57.45%, and the vaccination rate of influenza vaccine was 1.91% within one year before the survey. The willingness to receive influenza vaccine during pregnancy was only 3.57%. Multivariate analysis of influenza and influenza vaccine-related knowledge scores showed that the passing rate was positively correlated with education level and gestational age. In contrast, family income was negatively correlated with living in rural areas, working as migrant workers, and having no medical insurance. Multivariate analysis of vaccination intention showed that decreased effectiveness of influenza vaccine and increased adverse reactions decreased vaccination intention during pregnancy. Conclusions:The pregnant women in Suzhou pay more attention to influenza, and vaccination rates and intentions are generally low. Pregnant women with early and second trimester of pregnancy, low education, living in rural areas, working as migrant workers, and not purchasing medical insurance are the key groups to popularize the knowledge about influenza and influenza vaccine.

BackgroundThe depressive episode is one of the most prevalent mental illnesses worldwide. Relaxation therapy as a psychotherapy for depressive disorder has shown itself to be a viable tool, yet the existing research on relaxation therapy combined with sertraline in the treatment of depressive episodes in children and adolescents is severely limited. ObjectiveTo discuss the effect of relaxation therapy combined with sertraline on the new-onset depressive episodes in children and adolescents, and to provide references for the treatment of depressive episodes in children and adolescents. MethodsFrom January 1, 2019 to December 31, 2020, a sample of 422 children and adolescents with depressive episodes attending the Child Mental Health Department of Sichuan Mental Health Center and fulfilling the International Classification of Diseases, tenth edition (ICD-10) diagnostic criteria were enrolled, and they were classified into study group (n=208) and control group (n=214) using random number table method. All participants were offered sertraline, based on this, study group was assigned to relaxation therapy for 25~30 min per day, five days per week for a period of two weeks. Hamilton Depression Scale 24-item (HAMD-24) and Hamilton Anxiety Scale (HAMA) were applied at the enrollment, the end of 2 weeks of treatment and the end of the 2nd week after discharge. ResultsA total of 369 patients completed the study, including 185 in study group and 184 in control group. Analysis on HAMD-24 scores revealed a significant time effect, group effect and time×group interaction effect (F=813.279, 17.625, 8 994.905, P<0.01). Significant time effect, group effect, and time×group interaction effect were noted on HAMA scores (F=635.041, 10.716, 13 945.986, P<0.01). A reduction in HAMD-24 and HAMA scores was reported in study group at end of 2 weeks of treatment and end of the 2nd week after discharge compared with baseline (t=0.924, 0.359, P<0.01). At the end of the 2nd week after discharge, study group scored lower on HAMD-24 and HAMA compared to control group (t=0.210, 0.720, P<0.05). At the end of 2 weeks of treatment, study group resulted in greater improvements in depressive symptoms and anxiety symptoms than those of control group (95.14% vs. 66.30%, 89.18% vs. 71.74%, χ2=78.942, 22.526, P<0.05). The overall efficacy rate yielded no statistical difference between two groups at end of the 2nd week after discharge (P>0.05), and no statistical difference was found in the adverse reactions between the two groups (P>0.05). ConclusionCompared with sertraline alone, its combination with relaxation therapy may achieve a better short-term efficacy in the treatment of depressive episode in children and adolescents.

Chinese Journal of School Health 2024;45(12):1677-1680
Abstract
Prevention and control of myopia requires comprehensive measures. Based on the system established earlier, the system is revised and upgraded. The original system emphasizes comprehensive measures and proposes to focus on both the symptoms and root causes. These measures are summarized into six aspects, three address the root cause measures including health education, glasses optics and visual environment, and three address symptoms measures including eye exercises, physical therapy and drugs. The paper is comprehensively supplemented and analyzes the primary and the secondary, and promotes physical therapy from treating the symptoms to treat both the symptoms and the root causes. These improvement measures will help promote the prevention and control of myopia in children and adolescents.
