Anticipatory anxiety is a negative emotion that arises when individuals encounter potential threats or uncertainties in the future. It is the core symptom of a variety of anxiety disorders, and is closely associated with the occurrence, severity, treatment outcome, and prognosis of anxiety disorders, which has garnered a growing amount of focus in clinical practice. Nevertheless, scientific research on anticipatory anxiety continues to face obstacles such as unclear pathological mechanisms, the absence of simple and consistent self-assessment tools, and effective interventions. To improve understanding of the role of anticipatory anxiety in the diagnosis and treatment of anxiety disorders, this study reviews pertinent domestic and international literature, and briefly introduces the concept, assessment and measurement, activation paradigm, pathological mechanisms, and interventions of anticipatory anxiety.

Objective:This study aims to explore the intervention effects of five different intelligent rehabilitation technologies, namely immersive virtual reality (imVR), non-fully immersive virtual reality (Nf-imVR), augmented reality, brain-computer interface (BCI), and rehabilitation robot (RT), on the upper limb function and activities of daily living of stroke patients with upper limb dysfunction.Methods:A computer-based search was conducted in PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure, and Wanfang Databases for randomized controlled trials (RCT) on the intervention effects of different intelligent rehabilitation technologies on stroke patients with upper limb dysfunction. Manual search and other retrieval methods were also supplemented. The retrieval time limit was from the establishment of the databases to May 31, 2024. Data were extracted and the methodological quality was evaluated, and a network Meta-analysis was performed using Stata 17.0 software.Results:A total of 34 articals were included, involving 1 926 patients, and the studies included five intelligent rehabilitation technologies. The control groups all received dose-matched conventional physical training. The results of the network Meta-analysis showed that, compared with the dose-matched conventional physical training, in terms of improving upper limb function, the BCI had the best effect, followed by imVR, RT, Nf-imVR, and augmented reality in sequence; in terms of improving activities of daily living, the BCI still had the best effect, followed by imVR, RT, augmented reality, and Nf-imVR in sequence. The clustering ranking of upper limb function and activities of daily living was BCI >imVR > RT > Nf-imVR > augmented reality in turn.Conclusions:Intelligent rehabilitation technologies have advantages in improving the upper limb function and activities of daily living of stroke patients with upper limb dysfunction, and the BCI has obvious advantages.

Objective:To evaluate the effect of an obstetric artificial intelligence (AI) assistant combined with a family-centered health education model on maternal self-care ability, comfort status, and spousal caregiving ability.Methods:This prospective, single-center, parallel randomized controlled trial used 1∶1 randomization and was conducted as a superiority trial. Postpartum mothers and their spouses admitted to family-style single rooms at the Third Affiliated Hospital of Guangzhou Medical University between October 2024 and April 2025 were enrolled and randomly assigned to control or intervention groups using a random number table. The control group received conventional health education, while the intervention group received conventional health education plus the AI-assisted family-centered model. Interventions were administered at 2 hours, 6 hours, and 24 hours postpartum, and before discharge. Outcomes included maternal self-care ability, comfort status, and spousal caregiving ability, which were assessed at 2 hours postpartum and before discharge. Data were analyzed using independent and paired t-tests and Chi square tests. Results:Of the 88 mother-spouse dyads initially recruited, four were excluded due to mother-infant separation (e.g., neonatal jaundice), leaving 84 dyads (42 per group). After the intervention, the intervention group showed significantly higher maternal self-care ability scores [(192.81±13.80) vs. (181.00±21.41) scores, t=3.00], higher maternal comfort scores [(104.43±7.52) vs. (96.00±14.29) scores, t=3.38], and better spousal caregiving ability [(6.07±3.13) vs. (9.50±5.02) scores, t=－3.76] compared to the control group (all P<0.05). Conclusion:The obstetric AI assistant combined with a family-centered health education model significantly improved maternal self-care ability and comfort status, as well as spousal caregiving ability.

Objective To explore the effect of transcranial direct current stimulation(tDCS)in rehabilitation of swallowing function in stroke patients.Methods A total of 86 stroke patients diagnosed and treated in Affiliated Rehabilitation Hospital of Zhejiang Chinese Medical University from December 2022 to December 2023 were selected as study objects,and they were divided into observation group and control group according to random number table method,with 43 cases in each group.The control group received routine rehabilitation programs,while the observation group received tDCS therapy on the basis of control group.The swallowing function,actual swallowing process and quality of life of two groups were compared before and after intervention.Results After the intervention,standardized swallowing assessment scores of observation group were significantly lower than those of control group(P＜0.05).The scores of oral and pharyngeal phases of observation group were higher than those of control group(P＜0.05),and there was no significant difference in esophageal phase score between two groups(P＞0.05).The quality of life score of observation group was significantly higher than that of control group(P＜0.05).Conclusion tDCS can improve the swallowing function of stroke patients and improve the quality of life,which is worthy of clinical application.

Objective:To explore the role of chemokine CX3CL1/CX3CR1 in intraperitoneal metastasis of ovarian cancer in nude mice.Methods:Fifty SPF SD female nude mice were selected and randomly divided into normal group ( n=10) , ovarian cancer model group ( n=20) and CX3CL1 group ( n=20) by random number table method. Ovarian cancer model was not established in normal group, and ovarian cancer model was established in both ovarian cancer model group and CX3CL1 group. CX3CL1 group was given intraperitoneal injection of 20 μl CX3CL1 with a concentration of 10 ng/μl to observe the survival status of nude mice. Tumor mass, tumor volume, tumor inhibition rate, ascites rate and peritoneal metastasis rate were recorded. The pathological morphology of ovarian tissue was examined by HE staining, the expression of CX3CL1/CX3CR1 in ovarian tissue was detected by Western blotting, and the correlation between the expression of CX3CL1/CX3CR1 and peritoneal metastasis rate was analyzed by point two-column correlation. Results:During the administration, the mental state, activity, food and water intake of nude mice in the normal group were good with sensitive responses. The nude mice in the ovarian cancer model group showed signs of mental fatigue, reduced activity, less food and water intake, delayed response, as well as and a hard and gradually enlarged abdomen. The mental state, activity, food and water intake of nude mice in CX3CL1 group were better than those in ovarian cancer model group, and the abdominal hardness volume was smaller compared with that in ovarian cancer model group. The survival time of normal group, ovarian cancer model group and CX3CL1 group were (14.00±0.00) , (9.24±0.67) and (12.05±0.82) d, respectively, with a statistically significant difference ( F=22.27, P<0.001) . Further pair-to-pair comparisons showed that the normal group had the longest survival time, followed by the CX3CL1 group and the ovarian cancer model group (all P<0.05) . The tumor mass of ovarian cancer model group and CX3CL1 group was (1.31±0.21) and (0.62±0.13) g, respectively, with a statistically significant difference ( t=12.49, P<0.001) . The tumor volumes were (130.47±13.45) and (70.02±7.52) mm 3, respectively, with a statistically significant difference ( t=17.54, P<0.001) . The tumor suppression rates were (0.00±0.00) % and (48.96±4.74) %, respectively, with a statistically significant difference ( t=46.19, P<0.001) , the ascites rates were 60.00% (12/20) and 25.00% (5/20) , respectively, with a statistically significant difference ( χ2=5.01, P=0.025) . The abdominal metastasis rates were 80.00% (16/20) and 50.00% (10/20) , respectively, with a statistically significant difference ( χ2=3.96, P=0.047) . The results of HE staining showed that in the normal group, the ovarian tissue structure was complete, the follicles and oocytes developed normally with good shape, and no cancerous cells were found. The ovarian structure of the ovarian cancer model group was obviously destroyed, and a large number of cancerous cells could be seen. The nucleolus were deeply stained and the number increased. Compared with the ovarian cancer model group, the pathological structure was significantly improved, and the number of cancer cells was significantly decreased in the CX3CL1 group. The CX3CL1 protein relative expression levels in normal group, ovarian cancer model group and CX3CL1 group were 2.05±0.22, 1.33±0.11 and 2.41±0.24, respectively, with a statistically significant difference ( F=9.26, P<0.001) . The CX3CR1 protein relative expression levels were 1.99±0.21, 1.34±0.14, 2.73±0.31, respectively, with a statistically significant difference ( F=8.14, P<0.001) . Further pair-to-pair comparisons showed that compared with the normal group, the relative expression levels of CX3CL1 and CX3CR1 protein in ovarian cancer model group were significantly decreased, and the relative expression levels of CX3CL1 and CX3CR1 protein were higher in CX3CL1 group (all P<0.05) . Compared with ovarian cancer model group, the relative expression levels of CX3CL1 and CX3CR1 protein in ovarian tissue of CX3CL1 group were significantly increased (both P<0.05) . Correlation analysis showed that CX3CL1 and CX3CR1 expressions were negatively correlated with peritoneal metastasis rate ( r=-0.50, P=0.024; r=-0.58, P=0.012) . Conclusions:The expression of chemokine CX3CL1/CX3CR1 is down-regulated in ovarian cancer, and CX3CL1/CX3CR1 expression is negatively correlated with peritoneal metastasis of ovarian cancer. Activation of CX3CL1/CX3CR1 can significantly inhibit peritoneal metastasis of ovarian cancer.
